Abstract
A cover for the cargo area of a vehicle includes two rails secured to opposite sides of the cargo area of the vehicle.
A cover material is bounded by four peripheral rails. Two of the rails have the same cross-section and are located on two sides of the cover material. The other two rails are of a different configuration and are located on other two sides of the cover. A
biasing member, such as a-torsion bar, is inserted into the ends of each of the rails secured to the vehicle bed. The opposite end of the torsion bar is located in and slides within a cylinder. The opposite end of the cylinder includes a slide member. The slide members are located in channels formed in two of the rails. In the closed position, latches engage the torsion bars and hold the cover in place. To open the cover, two of the latches are disengaged, thereby allowing the cover to rise in response to the force of the biasing members. The cover pivots about a hinge formed by the engagement of the secured latches with the torsion bars.

DETATTEn DESCRTPTION OF T~F P~F~RRED RMRODTM~TS
In Figures 1-4 it can be seen that the cover assembly of the present invention generally includes a pair of side rails 10 secured to the side rails of the cargo bed 20 of the vehicle, four support members 30, one extending from each end of side rails 10 and a cover 40.
Side rails 10 each include a first channel 11, a second channel 12 and a third ch~nn~l 13 (Figure 5). Channel 11 includes a side wall 14 with a slit 15 therein that defines a lip 16 extending from the base 17 of side rail 10. Channels 12 and 13 share a common side wall 18. Channel 12 further includes an outer wall l9a with a slit l9b therein. Channel 13 includes an outer wall l9c with a slit 19d therein Side rails 10 are preferably formed from metal, such as aluminum.
A plastic bearing member 50 having an inner contour corresponding approximately to the outer contour of walls 14, l9a, and l9c of side rail 10 is secured to side rail 10. This is accomplished by inserting a pair of ears or tabs 51 and 52 into channels 12 and 13 through slits l9b and l9d so as to engage outer walls l9a and l9c as shown. When the cover is opened from either of the sides of the cargo bed, it pivots on bearing member 50, as described below.
Side rails 10 are secured to the top rail of cargo bed 20 by a plurality of clamps 60 (Figures 5 and 6). Each clamp 60 generally includes a base portion 70, a top portion 80 and a lever 90. Base 70 includes a first arm 71, a second arm 72 disposed at CA 02238698 1998-0~-27 a generally 90~ angle to first arm 71, and a third arm 73 disposed at a generally 90~ angle to second arm 72 and parallel to first arm 71. First arm 71 terminates in a foot 71a. Third arm 73 t~rm;n~tes in a hook 74. A recess 75 is formed at the juncture of second arm 72 and third arm 73.
Top portion 80 includes a first arm 81 terminating in a foot 82 at one end thereof. The opposite end of arm 81 is integrally formed with a second arm 83 that extends at a generally right angle thereto. A hook portion 84 extends from first arm 81 near its juncture with second arm 83.
As shown in the cut-away portion of Figure 6, each lever 90 includes a base 91 that extends upwardly and rearwardly at an angle and transitions into a curved c~mm; ng surface 91a. Levers 90 further include a pair of opposing side walls 92, a rear wall 93 and an open front 94. Rear wall 93 does not extend the entire length of side walls 92 and leaves an opening 95 at the rear of lever 90.
To secure side rail 10 to cargo bed 20, base 17 of side rail 10 is positioned adjacent the top rail as shown. Arm 71 is then positioned beneath the top rail such that arm 72 extends into the vehicle cargo area. me front edge 91b of base 91 of lever 90 is positioned in recess 75. Second arm 83 of top portion 80 is inserted through lever 90 as shown such that it extends through opening 95 and hook 84 engages hook 74. Foot 82 of first arm 81 is positioned behind lip 16 such that first arm 81 extends through slot 15. Lever 90 is then pivoted upwardly to the position shown in Figure 5. As this occurs, second arm 83 rides along c~mm; ng CA 112238698 1998-115-27 ~' surface 9la and base 91 pushes second arm 83 away from third arm 73. This causes top portion 80 to pivot around the juncture of hooks 74 and 84 and produces a resultant downward and outward force on rail 10 along the area of contact between foot 71a and foot 82 with base 17.
Although a specific clamp is disclosed for securing rail 10 to the vehicle, it should be understood that numerous other clamping mech~n; ~m~ may be utilized. However, as will be discussed below, a biasing member that forms a component of the present invention is secured to rail 10. The tension in the biasing member tends to cause rail 10 to lift off of the top rail of the vehicle cargo area. Accordingly, a clamp must be used that has sufficient clamping strength to overcome this tendency of rail 10 to separate from the top rail of the vehicle. In the particular embodiment shown, this is accomplished by placing foot 82 farther back in ch~nnel 11 than would otherwise be needed if no biasing member were used. Note also that the particular embodiment of clamp 60 disclosed is a universal design in that it will accommodate the cargo area top rails of all presently available pick-up trucks.
Figure 7 shows a perspective view of a support member 30.
In the embodiment shown, support member 30 is a strut, however, various support members could be used. Support member 30 includes a biasing member 100. In the embodiment shown, biasing member 100 is a torsion bar. Torsion bar 100 is received in a cylinder 101.
Torsion bar 100 includes a first segment 102, a second segment 103 and a third segment 104. First segment 102 is disposed at a generally right angle to second segment 103 and lays in CA 02238698 1998-0~-27 substantially the same plane as second segment 103. Third segment 104 is disposed at a substantially right angle to second segment 103 and lies in a plane angled approximately 60~ from the plane in which second segment 103 lies.
Cylinder 101 includes a first open end 105a and a second end 105b with a slide 106 disposed thereon. Slide 106 (Figures 7-9) includes a cap 107 having an ear 107a extending therefrom.
Slide 106 further includes a body 108 configured to slide within a portion of the periphery of the rigid cover, as described below.
Body 108 includes, at one end thereof, a pair of arms 108a, each of which includes an opening 108b therein. Arms 108a are configured to straddle ear 107a as shown. A pin is then inserted through openings 108b and ear 107a to pivotally secure body 108 to cap 107.
Figure 10 shows a perspective end view of side rail 10 with support member 30 secured thereto. As can be seen in this figure, an end cap 110 having an opening 111 therein has been placed on the end of side rail 10. Second segment 103 of torsion bar 100 extends through opening 111 and into channel 11 of side rail 10. A blocking member 112 is located in channel 11, adjacent slot 15, behind wall 14 and lip 16. Blocking member 112 is secured in place by a fastener, such as a screw 113. Blocking member 112 includes an opening 114 into which first segment 102 of torsion bar 100 extends. Blocking member 112 and end cap 110 secure support member 30 to side rail 10 such that torsion bar 100 cannot move along the longitudinal axis of channel 11. Note, however, that torsion bar 100 can be rotated in the direction of the arrow ~R"
CA 02238698 1998-0~-27 such that third segment 104 is positioned as indicated by dashed lines in Figure 10.
Figure 11 is a cross-sectional and partial perspective view taken along line 11-11 in Figure 1. This view illustrates a cross-sectional view of the periphery of cover 40. In particular, Figure 11 illustrates rail 120 that extends along both sides of cover 40. Rail 120 includes a first channel 121, a second channel 122 and a third channel 123. Second ~.h~nnel 122 is bounded by base 124, first lip 125, second lip 126 and top wall 127. Top wall 127 includes a nib 128 extending therefrom. Rail 120 further includes a top wall 129 positioned above and spaced apart from top wall 127.
A cushion 130 is positioned between top wall 127 and cover material 140, adjacent nib 128. Cushion 130 is preferably a compressible material that expands in the position shown so as to press cover material 140 against the inner surface of top wall 129.
This creates a seal between the upper surface of cover material 140 and the inner surface of top wall 129 and between cushion 130 and the upper surface of top wall 127 and helps keep the interior of the cargo area dry. Cushions 130 may be separate components placed between cover material 140 and rail 120. Alternatively, cushions 130 may be glued or otherwise secured to the underside of cover material 140. For example, cover material 140 could include a relatively rigid or stiff member with an outer covering wrapped around its edges. Cushions 130 could be placed on the underside of the rigid material and enclosed by the covering material.
Figure 12 is a cross-sectional and partial perspective view of rail 150 that extends along the front and rear of cover 40.
CA 02238698 1998-0~-27 Rail 150 includes a first channel 151, a second channel 152 and a third channel 153. Rear wall 154 of first channel 151 includes a slot 155 therein for receiving a seal 156. When cover 40 is lowered against the vehicle cargo bed, a seal 156 contacts the front and rear rails of the cargo bed and restricts the entry of moisture and debris. Second channel 152 is bounded by a base 152a, a first lip 152b, and a second lip 152c. Third channel 153 has a generally semicircular rear wall 153a and a vertically depending front wall 153b. A lip 153c extends into third channel 153 from vertically depending front wall 153b. Another wall 157 extends from vertically extending wall 153b and includes a nib 157a and recessed area 157b. Rail 150 further includes a top wall 158.
Cover material 140 is secured to rail 150 in the same manner as rail 120, as shown.
In one embodiment of the invention, cover 40 is rigid.
This may be accomplished in several ways. For example, cover material 140 can be a flexible material that is stretched taut between rails 120 and 150. Alternatively, cover material 140 may be a rigid material. As another alternative, if a sufficiently rigid material were used for cover 40, rails 120 and 150 could be completel-y eliminated.
Figures 13, 14 and 15 are, respectively, a top plan, and two side plan views of a corner piece 160 for securing rails 120 to rails 150. Corner piece 160 generally includes a body portion 161 with a first projection 161a, a second projection 161b, a third projection 161c, a fourth projection 161d and a fifth projection 161e extending from body 161 as shown. Projections 161a, 161b and CA 02238698 1998-0~-27 161c are configured so as to have the same general cross-sectional shape as channels 152, 153 and 154 of rail 150. In particular, second projection 161b includes a slot 161f therein for engaging lip 153c, as described below. Third projection 161c is a generally flat member configured to fit between walls 157 and 158 of peripheral rail 150. Fourth projection 161d is configured to fit within channel 123 of peripheral rails 120. Fifth projection 161e is similarly configured to fit within channel 122 of rails 120.
The corner piece 160 shown in Figures 15-17 is used to secure the passenger side rail 120 to rail 150 at the front of the cargo area.
An identical corner piece 160 is used to secure the passenger side rail 120 to rail 150 at the rear of the cargo area. In the corner piece 160 utilized to secure the driver side rail 120 to rail 150 at the front of the cargo area and the passenger side rail 120 to rail 150 at the rear of the cargo area, projections 161a-c are located on the face on which projections 161d and 161e are located in Figures 13-15, and projections 161d and 161e are located on the face of corner piece 160 on which projections 161a through 161c are shown.
Corner piece 160 further includes a channel 162 formed therein. When cover 40 is closed, torsion bars 100 rest within channel 162, as described below. A lock 163 extends through body 161 and operates a latch 164 disposed within body 161 adjacent channel 162. Latch 164, when closed, forms a hinge for pivoting cover 40 to the desired open position, as described below. If desired, a slot could be provided in each corner piece 160 to receive cover material 140 at the corners. Alternatively, cover CA 02238698 1998-0~-27 material 140 can be cut so as to mate with the outer surface of corner pieces 160 and be glued or otherwise sealed against the outer surface.
Figure 16 is a cross-sectional and partial plan view of the front driver's side corner of the cover assembly in the closed position. Note that end cap 110 is not shown. This view shows rail 150 secured to the left peripheral rail 120 by a corner piece 160. Cover material 140 and cushions 130 have been removed for clarity. In this view, it can be seen that projections 161a, 161b and 161c extend into rail 150. Similarly, projection 161d extends into channel 123 and projection 161e extends into channel 122 of rail 120. The corner pieces are fastened to rails 150 and 120 by inserting a screw or similar fastener through projections 161b and 161e and into rails 150 and 120 as shown. In the closed positioned, the curved juncture of segments 103 and 104 of torsion bar 100 lie within ch~nn~l 162 of corner piece 160. Slide 108 and cylinder 100 rest within channel 151 of rail 150. Latch 164, in the closed position, is positioned as shown beneath the juncture of segments 103 and 104 of torsion bar 100 to hold torsion bar 100 in place. When all four latches 164 are in the position shown, latches 164 hold the cover 40 in the closed position against the tension of torsion bars 100. Note also that the weight of cover 50 compresses bearing member 50 between rails 10 and 120, thus forming a seal to keep moisture out of the cargo area. Also, rails 10 do-not extend the entire length of the top rails of the cargo area in the embodiment shown. Accordingly, a foam, rubber or similar seal may be secured to the rail of the cargo area adjacent the ends of . CA 02238698 1998-0~-27 ~'' . .
rails 10 to seal any gap between corner pieces 160 and the top rails of the cargo area when the cover is closed.
To open the cover, the user first selects the side or end of the cargo bed from which access is desired. The user then inserts a key into locks 163 -in corner pieces 160 on that side or end and releases latches 164. When this occurs, the tension in the torsion bars 100 nested within those corner pieces 160 causes segments 104 to pivot upwardly. This in turn causes segments 104 to slide within cylinders 101 and cylinders 101 to pivot upwardly as well. As this occurs, slides 108 slide within channels 151 of rails 150. As cylinders 100 slide relative to segments 104 of torsion bars 100, support members 30 extend in length and raise cover 40 upwardly. While this occurs, the remaining latches 164 pivot about the juncture of segments 103 and 104 of the remaining two torsion bars 100 in channels 162 and act as a hinge to allow the cover to pivot upwardly. Thus, the cover begins to rise automatically when two of the locks 163 are released. Thus, the present invention permits the cover to be opened from which ever one of the sides or ends of the cargo bed the user desires.
Figure 17 shows a cross-sectional and partial plan view of the front, driver's side corner of the cover assembly of the present invention when the cover is being raised from the passenger side of the cargo bed of the vehicle. Note that channel 121 of the closed side pivots about bearing 50 on rail 10 and torsion bar 100 r~m~;n~ secured in corner piece 160. Although no shown, torsion bar 100 at the rear driver's side corner would likewise remain secured in its corner piece 160.

When opened in this manner, torsion bar 100 is released from corner piece 160 and channel 121 on the right rail 120 pivots about bearing 50 on the opposite side rail 10. Similarly, torsion bar 100 at the rear driver's side corner would be released from its corner piece 160.
If desired, the cover could be raised from the rear of the cargo bed by releasing locks 163 at both rear corners. The cover could be raised from the front by releasing both locks 163 at the front corners.
To remove cover 40 from the vehicle, all four latches 164 are disengaged from their respective torsion bars 100 and cover 40 is raised to a position above the cargo area. Cover 40 is then lifted such that torsion bars 100 slide completely out of cylinders 101. If desired, a safety lock or catch can be included to prevent inadvertent removal of cover 40. For example, a cord could be secured to rails 10 and rails 120 or 150 at each corner of the cargo area. The cords could also be connected to rails 10 and corner pieces 160. The length of the cords would be such that torsion bars 100 could not be completely removed from cylinders 101 without first disengaging the cords from either rails 10 or 120.
Although the present invention has been showed and described in detail, the same is to be taken by way of illustration only and not by way of limitation. Numerous changes can be made to the embodiment shown without departing from the scope of the CA 02238698 1998-0~-27 invention. For example, various latch and/or hinge mechanisms could be used in place of latch 164. Lock 163, could be completely eliminated. The various components, including rails 10, 120 and 150 and corner pieces 160, could be of configurations other than those shown. Accordingly, the present invention is to be limited only by the terms of the claims appended hereto.

DETATTEn DESCRTPTION OF T~F P~F~RRED RMRODTM~TS
In Figures 1-4 it can be seen that the cover assembly of the present invention generally includes a pair of side rails 10 secured to the side rails of the cargo bed 20 of the vehicle, four support members 30, one extending from each end of side rails 10 and a cover 40.
Side rails 10 each include a first channel 11, a second channel 12 and a third ch~nn~l 13 (Figure 5). Channel 11 includes a side wall 14 with a slit 15 therein that defines a lip 16 extending from the base 17 of side rail 10. Channels 12 and 13 share a common side wall 18. Channel 12 further includes an outer wall l9a with a slit l9b therein. Channel 13 includes an outer wall l9c with a slit 19d therein Side rails 10 are preferably formed from metal, such as aluminum.
A plastic bearing member 50 having an inner contour corresponding approximately to the outer contour of walls 14, l9a, and l9c of side rail 10 is secured to side rail 10. This is accomplished by inserting a pair of ears or tabs 51 and 52 into channels 12 and 13 through slits l9b and l9d so as to engage outer walls l9a and l9c as shown. When the cover is opened from either of the sides of the cargo bed, it pivots on bearing member 50, as described below.
Side rails 10 are secured to the top rail of cargo bed 20 by a plurality of clamps 60 (Figures 5 and 6). Each clamp 60 generally includes a base portion 70, a top portion 80 and a lever 90. Base 70 includes a first arm 71, a second arm 72 disposed at CA 02238698 1998-0~-27 a generally 90~ angle to first arm 71, and a third arm 73 disposed at a generally 90~ angle to second arm 72 and parallel to first arm 71. First arm 71 terminates in a foot 71a. Third arm 73 t~rm;n~tes in a hook 74. A recess 75 is formed at the juncture of second arm 72 and third arm 73.
Top portion 80 includes a first arm 81 terminating in a foot 82 at one end thereof. The opposite end of arm 81 is integrally formed with a second arm 83 that extends at a generally right angle thereto. A hook portion 84 extends from first arm 81 near its juncture with second arm 83.
As shown in the cut-away portion of Figure 6, each lever 90 includes a base 91 that extends upwardly and rearwardly at an angle and transitions into a curved c~mm; ng surface 91a. Levers 90 further include a pair of opposing side walls 92, a rear wall 93 and an open front 94. Rear wall 93 does not extend the entire length of side walls 92 and leaves an opening 95 at the rear of lever 90.
To secure side rail 10 to cargo bed 20, base 17 of side rail 10 is positioned adjacent the top rail as shown. Arm 71 is then positioned beneath the top rail such that arm 72 extends into the vehicle cargo area. me front edge 91b of base 91 of lever 90 is positioned in recess 75. Second arm 83 of top portion 80 is inserted through lever 90 as shown such that it extends through opening 95 and hook 84 engages hook 74. Foot 82 of first arm 81 is positioned behind lip 16 such that first arm 81 extends through slot 15. Lever 90 is then pivoted upwardly to the position shown in Figure 5. As this occurs, second arm 83 rides along c~mm; ng CA 112238698 1998-115-27 ~' surface 9la and base 91 pushes second arm 83 away from third arm 73. This causes top portion 80 to pivot around the juncture of hooks 74 and 84 and produces a resultant downward and outward force on rail 10 along the area of contact between foot 71a and foot 82 with base 17.
Although a specific clamp is disclosed for securing rail 10 to the vehicle, it should be understood that numerous other clamping mech~n; ~m~ may be utilized. However, as will be discussed below, a biasing member that forms a component of the present invention is secured to rail 10. The tension in the biasing member tends to cause rail 10 to lift off of the top rail of the vehicle cargo area. Accordingly, a clamp must be used that has sufficient clamping strength to overcome this tendency of rail 10 to separate from the top rail of the vehicle. In the particular embodiment shown, this is accomplished by placing foot 82 farther back in ch~nnel 11 than would otherwise be needed if no biasing member were used. Note also that the particular embodiment of clamp 60 disclosed is a universal design in that it will accommodate the cargo area top rails of all presently available pick-up trucks.
Figure 7 shows a perspective view of a support member 30.
In the embodiment shown, support member 30 is a strut, however, various support members could be used. Support member 30 includes a biasing member 100. In the embodiment shown, biasing member 100 is a torsion bar. Torsion bar 100 is received in a cylinder 101.
Torsion bar 100 includes a first segment 102, a second segment 103 and a third segment 104. First segment 102 is disposed at a generally right angle to second segment 103 and lays in CA 02238698 1998-0~-27 substantially the same plane as second segment 103. Third segment 104 is disposed at a substantially right angle to second segment 103 and lies in a plane angled approximately 60~ from the plane in which second segment 103 lies.
Cylinder 101 includes a first open end 105a and a second end 105b with a slide 106 disposed thereon. Slide 106 (Figures 7-9) includes a cap 107 having an ear 107a extending therefrom.
Slide 106 further includes a body 108 configured to slide within a portion of the periphery of the rigid cover, as described below.
Body 108 includes, at one end thereof, a pair of arms 108a, each of which includes an opening 108b therein. Arms 108a are configured to straddle ear 107a as shown. A pin is then inserted through openings 108b and ear 107a to pivotally secure body 108 to cap 107.
Figure 10 shows a perspective end view of side rail 10 with support member 30 secured thereto. As can be seen in this figure, an end cap 110 having an opening 111 therein has been placed on the end of side rail 10. Second segment 103 of torsion bar 100 extends through opening 111 and into channel 11 of side rail 10. A blocking member 112 is located in channel 11, adjacent slot 15, behind wall 14 and lip 16. Blocking member 112 is secured in place by a fastener, such as a screw 113. Blocking member 112 includes an opening 114 into which first segment 102 of torsion bar 100 extends. Blocking member 112 and end cap 110 secure support member 30 to side rail 10 such that torsion bar 100 cannot move along the longitudinal axis of channel 11. Note, however, that torsion bar 100 can be rotated in the direction of the arrow ~R"
CA 02238698 1998-0~-27 such that third segment 104 is positioned as indicated by dashed lines in Figure 10.
Figure 11 is a cross-sectional and partial perspective view taken along line 11-11 in Figure 1. This view illustrates a cross-sectional view of the periphery of cover 40. In particular, Figure 11 illustrates rail 120 that extends along both sides of cover 40. Rail 120 includes a first channel 121, a second channel 122 and a third channel 123. Second ~.h~nnel 122 is bounded by base 124, first lip 125, second lip 126 and top wall 127. Top wall 127 includes a nib 128 extending therefrom. Rail 120 further includes a top wall 129 positioned above and spaced apart from top wall 127.
A cushion 130 is positioned between top wall 127 and cover material 140, adjacent nib 128. Cushion 130 is preferably a compressible material that expands in the position shown so as to press cover material 140 against the inner surface of top wall 129.
This creates a seal between the upper surface of cover material 140 and the inner surface of top wall 129 and between cushion 130 and the upper surface of top wall 127 and helps keep the interior of the cargo area dry. Cushions 130 may be separate components placed between cover material 140 and rail 120. Alternatively, cushions 130 may be glued or otherwise secured to the underside of cover material 140. For example, cover material 140 could include a relatively rigid or stiff member with an outer covering wrapped around its edges. Cushions 130 could be placed on the underside of the rigid material and enclosed by the covering material.
Figure 12 is a cross-sectional and partial perspective view of rail 150 that extends along the front and rear of cover 40.
CA 02238698 1998-0~-27 Rail 150 includes a first channel 151, a second channel 152 and a third channel 153. Rear wall 154 of first channel 151 includes a slot 155 therein for receiving a seal 156. When cover 40 is lowered against the vehicle cargo bed, a seal 156 contacts the front and rear rails of the cargo bed and restricts the entry of moisture and debris. Second channel 152 is bounded by a base 152a, a first lip 152b, and a second lip 152c. Third channel 153 has a generally semicircular rear wall 153a and a vertically depending front wall 153b. A lip 153c extends into third channel 153 from vertically depending front wall 153b. Another wall 157 extends from vertically extending wall 153b and includes a nib 157a and recessed area 157b. Rail 150 further includes a top wall 158.
Cover material 140 is secured to rail 150 in the same manner as rail 120, as shown.
In one embodiment of the invention, cover 40 is rigid.
This may be accomplished in several ways. For example, cover material 140 can be a flexible material that is stretched taut between rails 120 and 150. Alternatively, cover material 140 may be a rigid material. As another alternative, if a sufficiently rigid material were used for cover 40, rails 120 and 150 could be completel-y eliminated.
Figures 13, 14 and 15 are, respectively, a top plan, and two side plan views of a corner piece 160 for securing rails 120 to rails 150. Corner piece 160 generally includes a body portion 161 with a first projection 161a, a second projection 161b, a third projection 161c, a fourth projection 161d and a fifth projection 161e extending from body 161 as shown. Projections 161a, 161b and CA 02238698 1998-0~-27 161c are configured so as to have the same general cross-sectional shape as channels 152, 153 and 154 of rail 150. In particular, second projection 161b includes a slot 161f therein for engaging lip 153c, as described below. Third projection 161c is a generally flat member configured to fit between walls 157 and 158 of peripheral rail 150. Fourth projection 161d is configured to fit within channel 123 of peripheral rails 120. Fifth projection 161e is similarly configured to fit within channel 122 of rails 120.
The corner piece 160 shown in Figures 15-17 is used to secure the passenger side rail 120 to rail 150 at the front of the cargo area.
An identical corner piece 160 is used to secure the passenger side rail 120 to rail 150 at the rear of the cargo area. In the corner piece 160 utilized to secure the driver side rail 120 to rail 150 at the front of the cargo area and the passenger side rail 120 to rail 150 at the rear of the cargo area, projections 161a-c are located on the face on which projections 161d and 161e are located in Figures 13-15, and projections 161d and 161e are located on the face of corner piece 160 on which projections 161a through 161c are shown.
Corner piece 160 further includes a channel 162 formed therein. When cover 40 is closed, torsion bars 100 rest within channel 162, as described below. A lock 163 extends through body 161 and operates a latch 164 disposed within body 161 adjacent channel 162. Latch 164, when closed, forms a hinge for pivoting cover 40 to the desired open position, as described below. If desired, a slot could be provided in each corner piece 160 to receive cover material 140 at the corners. Alternatively, cover CA 02238698 1998-0~-27 material 140 can be cut so as to mate with the outer surface of corner pieces 160 and be glued or otherwise sealed against the outer surface.
Figure 16 is a cross-sectional and partial plan view of the front driver's side corner of the cover assembly in the closed position. Note that end cap 110 is not shown. This view shows rail 150 secured to the left peripheral rail 120 by a corner piece 160. Cover material 140 and cushions 130 have been removed for clarity. In this view, it can be seen that projections 161a, 161b and 161c extend into rail 150. Similarly, projection 161d extends into channel 123 and projection 161e extends into channel 122 of rail 120. The corner pieces are fastened to rails 150 and 120 by inserting a screw or similar fastener through projections 161b and 161e and into rails 150 and 120 as shown. In the closed positioned, the curved juncture of segments 103 and 104 of torsion bar 100 lie within ch~nn~l 162 of corner piece 160. Slide 108 and cylinder 100 rest within channel 151 of rail 150. Latch 164, in the closed position, is positioned as shown beneath the juncture of segments 103 and 104 of torsion bar 100 to hold torsion bar 100 in place. When all four latches 164 are in the position shown, latches 164 hold the cover 40 in the closed position against the tension of torsion bars 100. Note also that the weight of cover 50 compresses bearing member 50 between rails 10 and 120, thus forming a seal to keep moisture out of the cargo area. Also, rails 10 do-not extend the entire length of the top rails of the cargo area in the embodiment shown. Accordingly, a foam, rubber or similar seal may be secured to the rail of the cargo area adjacent the ends of . CA 02238698 1998-0~-27 ~'' . .
rails 10 to seal any gap between corner pieces 160 and the top rails of the cargo area when the cover is closed.
To open the cover, the user first selects the side or end of the cargo bed from which access is desired. The user then inserts a key into locks 163 -in corner pieces 160 on that side or end and releases latches 164. When this occurs, the tension in the torsion bars 100 nested within those corner pieces 160 causes segments 104 to pivot upwardly. This in turn causes segments 104 to slide within cylinders 101 and cylinders 101 to pivot upwardly as well. As this occurs, slides 108 slide within channels 151 of rails 150. As cylinders 100 slide relative to segments 104 of torsion bars 100, support members 30 extend in length and raise cover 40 upwardly. While this occurs, the remaining latches 164 pivot about the juncture of segments 103 and 104 of the remaining two torsion bars 100 in channels 162 and act as a hinge to allow the cover to pivot upwardly. Thus, the cover begins to rise automatically when two of the locks 163 are released. Thus, the present invention permits the cover to be opened from which ever one of the sides or ends of the cargo bed the user desires.
Figure 17 shows a cross-sectional and partial plan view of the front, driver's side corner of the cover assembly of the present invention when the cover is being raised from the passenger side of the cargo bed of the vehicle. Note that channel 121 of the closed side pivots about bearing 50 on rail 10 and torsion bar 100 r~m~;n~ secured in corner piece 160. Although no shown, torsion bar 100 at the rear driver's side corner would likewise remain secured in its corner piece 160.
CA 02238698 1998-0~-27 Figure 18 shows a cross-sectional and partial plan view of the front, driver's side corner of the cover assembly of the present invention when the cover is being raised from the driver's side of the cargo bed of the vehicle. When opened in this manner, torsion bar 100 is released from corner piece 160 and channel 121 on the right rail 120 pivots about bearing 50 on the opposite side rail 10. Similarly, torsion bar 100 at the rear driver's side corner would be released from its corner piece 160.
If desired, the cover could be raised from the rear of the cargo bed by releasing locks 163 at both rear corners. The cover could be raised from the front by releasing both locks 163 at the front corners.
To remove cover 40 from the vehicle, all four latches 164 are disengaged from their respective torsion bars 100 and cover 40 is raised to a position above the cargo area. Cover 40 is then lifted such that torsion bars 100 slide completely out of cylinders 101. If desired, a safety lock or catch can be included to prevent inadvertent removal of cover 40. For example, a cord could be secured to rails 10 and rails 120 or 150 at each corner of the cargo area. The cords could also be connected to rails 10 and corner pieces 160. The length of the cords would be such that torsion bars 100 could not be completely removed from cylinders 101 without first disengaging the cords from either rails 10 or 120.
Although the present invention has been showed and described in detail, the same is to be taken by way of illustration only and not by way of limitation. Numerous changes can be made to the embodiment shown without departing from the scope of the CA 02238698 1998-0~-27 invention. For example, various latch and/or hinge mechanisms could be used in place of latch 164. Lock 163, could be completely eliminated. The various components, including rails 10, 120 and 150 and corner pieces 160, could be of configurations other than those shown. Accordingly, the present invention is to be limited only by the terms of the claims appended hereto.
