Abstract
A tool (1) for inserting screwed, anchoring devices, with the tool being capable of being operated manually or automatically, comprises an elongated handle (12), a shaft (10) that extends between the ends of said handle with a tip end (14) that extends from the front end of the handle and a distal end (16) that lies in the rear end of the handle. The rear end of the shaft has a well (24) that extends along the centerline of the shaft, with the well being configured to receive a standard drill bit of the type that fits within the chuck of a power drill. The depth and wall thickness of the well (24) are such that the well allows a drill bit to enter the well to a depth so that there is ample surface area of the well interior wall in contact with the drill bit to absorb the torque applied to the tool by the power drill. The tip end (14) of the shaft may be configured to attach to one of the anchoring devices, or it may be configured with a well (27) for receiving any one of a number of screw bits that may be used with the tool to insert an anchor which has a head configuration that matches that of the screw bit. Anchoring devices suitable for use with this tool include screws, bolts, nuts, and socketed devices.

z1 zz 2. DESCRIPTION OF THE RELATED ART
23 Cordless, power drills have, in many 'instances, made significant z4 improvements in the efficiency with which many construction jobs can be completed.
zs Because of these improvements, their use in many construction trades have become zs very widespread in the past ten to fifteen years.
z~ Additionally, their use has tended to make those who use them more mobile in zs that they no longer have to be tethered by a drill's cord to a nearby power outlet. With 29 this increased mobility, construction workers often find it even more advantageous to 3o wear tool belts which allow them to carry greater numbers of tools on their belts so 31 that they don't have to make frequent trips back to a centralized tool box.
i Such tool belts will often include spaces for carrying a number of items for z attaching a wide assortment of screw-type anchors. These tools will typically include 3 various hand tools (e.g., screwdrivers, socket and Allen wrenches) and power tools 4 (e.g., cordless drill and appropriate drill bits), and can consume a significant portion of s the storage spaces available on a typical tool belt. Additionally, because of the size 6 differences between such tools, the smaller items (e.g., drill bits) can often be difficult 7 to find in a typical tool belt and are often at risk of being lost.
s The usefulness of such tool belts could be improved upon if there were some 9 way to consolidate some of these tools. This sort of logic has over the years led to the io invention of a large number of hand tools that have multiple, interchangeable tips i i which can be used on a wide range of anchors. For example, see USPN
6,374,711 to iz Anderson for a "50-In-1 Screwdriver and Socket Driver."
i3 Additionally, some attempts have been made to design various hand tools so is as to adapt them to be driven by attaching their distal ends to some form of an is auxiliary drive device, including a power drill. For example, for a tap wrench, see i6 USPN 3,738,768; for a screwdriver, see USPN 2,620,001 and 4,437,365, and for an m extension for a socket wrench, see USPN 5,950,507.
is As far as a consolidation of the various tools that might be carned in a tool belt, the concept of adapting a hand tool such that it might be driven by a power tool zo seems very appealing. However, the prior art applications (e.g., USPN
4,437,365) of zi this idea seem to not have met with much success, as one does not see such items in zz the marketplace or in use in the construction industry. This situation exists in spite of 23 the fact that the increased use of cordless drills would seem to make the use of such 24 tools more appealing.
zs One potential reason, that one does not see in the marketplace hand tools z6 adapted so that they are capable of being driven by power drills, is that such prior art a~ devices have always had certain limitations that greatly diminishes their usefulness.
zs For example, the screwdriver of USPN 2,620,001 as seen in FIG. 1, which was z9 intended to be driven only by a non-powered, handheld device, has the limitation that so if one were to try to drive it by a power drill, it could present a potential physical si danger to its user from its use. This danger exists because an anchor being driven by 1 such a device can be launched sideways due to the anchor being misaligned on its tip z and the high rate of angular rotation being applied by the drill.
s The screwdriver of USPN 4,437,365 has this same problem. Additionally, to a be driven by a power drill, it has the disadvantage of requiring the use of a special s coupling. This coupling ends up being just one more accessory with which a user s must keep up. See FIG. 2 from USPN 4,437,365.
7 Additionally, none of the prior art devices are very versatile. This is due to s their being designed so that they are able to work with only one type of anchor.
9 Additionally, they can only be used for inserting anchors, and not for removing them.
to Thus, despite this prior art, one finds that further improvements are needed to 11 make more versatile and useful the hand tools and cordless drill that the typical Iz construction worker carries in his/her tool belt. Such improvements should also help to is reduce the number of items that must be carried in a tool belt, while also helping to 14 make the user of such improved tools more efficient in the act of installing a wide is assortment of screw anchors.

z1 There has been summarized above, rather broadly, the prior art that is related zz to the present invention in order that the context of the present invention may be better zs understood and appreciated.

s DESCRIPTION OF THE PREFERRED EMBODllVIENT
s Referring now to the drawings wherein are shown preferred embodiments and 6 wherein like reference numerals designate like elements throughout, there is shown in FIG. 3 a perspective view of an embodiment of the present invention in the form of an s improved tool (1) or screwdriver which has been modified so that it can easily be driven 9 by using a standard screwdriver drill bit (2) with a conventional, cordless power drill ~a (3).
m This improved screwdriver (1) includes a shaft (10) and a handle (12). The ~a shaft (10) has a tip end (14) and extends all the way through the handle so as to have a distal end (16) that is flush with the handle's rear end surface (18). The tip (14) Ia shown in FIG. 3 has a straight or knife edge (20) designed to engage a single slotted is head of a screw. However, it will be appreciated that the tip (14) may take other 16 forms such as, for example, that intended to engage the cross slot of a PHILLIPS head m screw. See FIG. 4 for illustrative examples of various types of screw heads 4 that i a can be driven by various embodiments of the present invention.
i9 This screwdriver's handle (12) may be provided with axially extending zo grooves (22) on its surface to enable the handle to be gripped conveniently by the zi user. These handles will usually be molded of plastic or other like material.
zz The distal end (16) of the shaft extension has a well (24) within it that is z3 configured to receive the end of a standard drill bit (2), such as any of those shown on z4 the right side of FIG. 4. The depth of this well is such that it can allow the bit to enter zs the well to a depth so that there is ample surface area of the well interior wall in zs contact with the drill bit to absorb with little deformation the larger torques applied z7 by a power drill. To aid in holding a drill bit, which is typically made of steel and is zs an iron containing material, in place within this well (24), the distal end (16) of the z9 shaft can be magnetized so that it will magnetically attract an iron containing drill bit.
3o If the shaft is of a magnetizable material, this can be accomplished by magnetizing 3i the shaft directly. If not, a suitably shaped magnet can be placed in proximity to the i shaft's distal end (16). Similarly, the tip end (14) of the shaft (10) can be magnetized z to aid in holding iron-containing screws or other anchors on the shaft's tip.
s The shaft of this embodiment of a screwdriver according to the present a invention has a tube-like screwguide (26) that encircles the shaft (10) in such a s manner that the shaft of the screwdriver (1) can rotate freely within this screwguide 6 (26) while the screwguide itself is held stationary. The screwguide (26) also can be 7 moved laterally on the shaft (10). This screwguide is used to guide screws into place s as the screwdriver (1) is powered by a drill.
9 To use this screwguide (26), one places a screw on the tip (14) of the shaft io (10) and then slides the screwguide forward to enclose the screw. One then places a i i hand on the outer surface of the screwguide (26) to hold it stationary, thereby iz stabilizing the position of both the screw and the screwdriver (1).
is When power it applied to the handle's distal end (16), the shaft (10) turns and i4 drives the screw forward as it is held in place by the screwguide (26) until it is fully is anchored in its desired location. This screwguide (26) is also seen to serve the safety i6 purpose of preventing a misaligned screw on the tip (14) of the screwdriver from m being thrown off line and possibly even launched sideways, so as to become a threat 1 s to those in the area, when a large amount of torque and a high rotation rate are applied i9 to the screw. If the tip end (14) of the shaft (10) has been magnetized, the choice of zo the material for the construction of the screwguide (26) will be made so that the zi screwguide is not attracted by the magnetic properties of the shaft's tip end (14).
zz To aide the further versatility of such a screwdriver, another preferred zs embodiment of the present invention consists of a screwdriver similar to that za described above, but having a tip end (14) that is configured so that it can as accommodate any one of a number of multiple ends or screw bits. For example, if the 26 tip end (14) has a hexagonal shaped well (27) in its tip, it can interchangeably z7 accommodate any of the screw drivers or drill bits (5) shown on the right hand side in za FIG. 4. To aid in holding such drivers in place, the tip end (14) would also be z9 magnetized. ' 3o To make it easy to keep up with various driver or drill bits (5), another si embodiment of the present invention has a handle which has slots (15) around the i perimeter of its front (17) face. These slots (15) are configured so as to accommodate z and allow one of the various driver bits to be inserted and stored within each of the s slots. See FIG. 6.
a In addition to performing as a screwdriver, this device can easily be made to s perform as a nut or other type of driver by configuring the tip (14) of the shaft (10) so 6 that it can mate with various types of nuts, bolts or sockets. Again, the tip can be magnetized to aide in holding an anchor on the tip. Some of the types of drivers (7) s that can be used with this device are shown on the right side of FIG. 5, while shown 9 on the left side of are the various bolts, nuts, sockets (6), etc. that can be inserted with io these drivers.
i i For various low torque applications, it may be desirable to configure these iz devices so that they consist not of a single shaft which extends all the way thorough i3 the handle, but to insert into the end surface (18) of the handle (12) a metal insert (28) is which has within it an especially configured, magnetized well (24) for receiving a ~s standard drill bit. See FIG. 7.
is It should also be noted, that for some specialized applications, it may be i7 desirable to configure these devices so that they have a male shaft adapter (30) that is extends from the handle's end surface (18) rather than have the well (24), or female i9 adapter, at the distal end (16) of the shaft (12). In such an embodiment, this adapter zo (30) would be configured so that it could be directly accommodated and fit within the zi chuck of a standard electric drill. See FIG. 8.
zz In still other applications, it may be desirable to configure the present z3 invention into another embodiment in which the shaft does not extends all the way za thorough the handle. This embodiments has an insert (32) which has a well (33) that zs contains an especially configured, male, pop-out adapter (34). See FIG. 9.
The insert zs (32) also has a spring mechanism (36) which is operable by an extension (38) that z7 extends to a location (40) on the outer surface of the handle (12) and serves to make zs the adapter (34) interchangeable between a first and a second position. In its first 29 position, this adapter (34) extends from the handle (12), and in its second position, 3o the adapter is retracted into the insert (32). In its first position, this adapter is easily 3i fitted within the chuck of an electric drill, while in its second or retracted position, the adapter does not interfere with a user who wishes to grip the device by its handle and z use it, without the aid of an electric drill, to install a screw anchor.
s Another preferred embodiment of a driver device (1) having multiple tip a interchangeable capability is shown in FIG. 10. It consists of a shaft (42) and a s handle (44). The shaft (42) has front (46) and rear (48) ends. Each of these has an 6 especially configured well (50), (52).
7 The rear end well (52), as before, is configured to receive the end of a s standard drill bit (2), such as any of those shown on the right side of FIG.
4. The 9 depth of this well (52) is such that it can allow the bit to enter the well to a depth so io that there is ample surface area of the well interior wall in contact with the drill bit so i i as to absorb with little deformation the larger torques applied by a power drill. To aid iz in holding a drill bit in place within this well (52), the rear end (48) of the shaft can is be magnetized so that it will magnetically attract an iron containing drill bit.
is The front end well (50) is configured to receive the rear end (56) of any one of is a number of interchangeable shaft extensions (54). Again, the depth and wall is thickness of this well (50) is chosen so as to accommodate the expected torque to be i7 applied by the device. Both the front (58) and the rear (56) ends of these extensions is (54) are configured in the form of a driver head which is to be used to drive a specific i9 type of screw or anchor, such as those shown in FIG. 4. These ends will preferably be zo magnetized to aid in holding iron-containing screws or other anchors on either of the zi extension's tips.
22 For higher torque applications, a portion of length of the shaft extension (54) 23 Can have one or more ribs (60). With such an extension, the front well (50) would z4 then be configured so as to have matching slots (62) to accommodate the ribs (60) so zs that the extension (54) can still fit within the front well (50).
zs For even more versatility, an embodiment of the present invention is provided z~ with a two piece shaft, front (66) and rear (68), and a clutching mechanism (70) in the zs handle (72) which enables the tip (74) of the front shaft (66) to be rotated in either a z9 forward, for inserting a screw anchor, or a reverse, for withdrawing a screw anchor, so mode of operation. The rear shaft (68) has a well (76) in its rear end so that it can be 3i driven by the insertion of the bit of an electric drill. The front portion of this rear i shaft has a connecting end (73) that connects with the clutching mechanism (70) 2 which also connects with the rear portion (75) of the front shaft (66). This 3 embodiment is also provided with the ability to fit multiple types of bits into a well 4 (78) that exists on the tip (74) of the front shaft. It has storage slots (80) on the front s face (82) of the handle (72) for storage of the various bits that can be used with the 6 device. See FIG. 11.
7 As to a further discussion of the manner of usage and operation of the present s invention, the same should be apparent from the above description.
Accordingly, no 9 further discussion relating to the manner of usage and operation will be provided.
io With respect to the above description then, it is to be realized that the n optimum dimensional relationships for the parts of the invention, to include iz variations in size, materials, shape, form, function and manner of operation, assembly i3 and use, are deemed readily apparent and obvious to one skilled in the art, and all i4 equivalent relationships to those illustrated in the drawings and described in the is specification are intended to be encompassed by the present invention.
i6 The foregoing is considered as illustrative only of the principles of the i7 invention. Further, since numerous modifications and changes will readily occur to is those skilled in the art, it is not desired to limit the invention to the exact construction i9 and operation shown and described, and accordingly, all suitable modifications and 2o equivalents may be resorted to, falling within the scope of the invention as hereinafter 2i set forth in the claims.
s The usefulness of such tool belts could be improved upon if there were some 9 way to consolidate some of these tools. This sort of logic has over the years led to the io invention of a large number of hand tools that have multiple, interchangeable tips i i which can be used on a wide range of anchors. For example, see USPN
6,374,711 to iz Anderson for a "50-In-1 Screwdriver and Socket Driver."
i3 Additionally, some attempts have been made to design various hand tools so is as to adapt them to be driven by attaching their distal ends to some form of an is auxiliary drive device, including a power drill. For example, for a tap wrench, see i6 USPN 3,738,768; for a screwdriver, see USPN 2,620,001 and 4,437,365, and for an m extension for a socket wrench, see USPN 5,950,507.
is As far as a consolidation of the various tools that might be carned in a tool belt, the concept of adapting a hand tool such that it might be driven by a power tool zo seems very appealing. However, the prior art applications (e.g., USPN
4,437,365) of zi this idea seem to not have met with much success, as one does not see such items in zz the marketplace or in use in the construction industry. This situation exists in spite of 23 the fact that the increased use of cordless drills would seem to make the use of such 24 tools more appealing.
zs One potential reason, that one does not see in the marketplace hand tools z6 adapted so that they are capable of being driven by power drills, is that such prior art a~ devices have always had certain limitations that greatly diminishes their usefulness.
zs For example, the screwdriver of USPN 2,620,001 as seen in FIG. 1, which was z9 intended to be driven only by a non-powered, handheld device, has the limitation that so if one were to try to drive it by a power drill, it could present a potential physical si danger to its user from its use. This danger exists because an anchor being driven by 1 such a device can be launched sideways due to the anchor being misaligned on its tip z and the high rate of angular rotation being applied by the drill.
s The screwdriver of USPN 4,437,365 has this same problem. Additionally, to a be driven by a power drill, it has the disadvantage of requiring the use of a special s coupling. This coupling ends up being just one more accessory with which a user s must keep up. See FIG. 2 from USPN 4,437,365.
7 Additionally, none of the prior art devices are very versatile. This is due to s their being designed so that they are able to work with only one type of anchor.
9 Additionally, they can only be used for inserting anchors, and not for removing them.
to Thus, despite this prior art, one finds that further improvements are needed to 11 make more versatile and useful the hand tools and cordless drill that the typical Iz construction worker carries in his/her tool belt. Such improvements should also help to is reduce the number of items that must be carried in a tool belt, while also helping to 14 make the user of such improved tools more efficient in the act of installing a wide is assortment of screw anchors.

to 1z is SUMMARY OF THE INVENTION
Is The present invention is generally directed to satisfying the need set forth above 19 and the problems identified with prior retractable, tape measures.
zo A preferred embodiment of the present invention is a tool for inserting screwed, z1 anchoring devices, with the tool capable of being operated manually or automatically.

s DESCRIPTION OF THE PREFERRED EMBODllVIENT
s Referring now to the drawings wherein are shown preferred embodiments and 6 wherein like reference numerals designate like elements throughout, there is shown in FIG. 3 a perspective view of an embodiment of the present invention in the form of an s improved tool (1) or screwdriver which has been modified so that it can easily be driven 9 by using a standard screwdriver drill bit (2) with a conventional, cordless power drill ~a (3).
m This improved screwdriver (1) includes a shaft (10) and a handle (12). The ~a shaft (10) has a tip end (14) and extends all the way through the handle so as to have a distal end (16) that is flush with the handle's rear end surface (18). The tip (14) Ia shown in FIG. 3 has a straight or knife edge (20) designed to engage a single slotted is head of a screw. However, it will be appreciated that the tip (14) may take other 16 forms such as, for example, that intended to engage the cross slot of a PHILLIPS head m screw. See FIG. 4 for illustrative examples of various types of screw heads 4 that i a can be driven by various embodiments of the present invention.
i9 This screwdriver's handle (12) may be provided with axially extending zo grooves (22) on its surface to enable the handle to be gripped conveniently by the zi user. These handles will usually be molded of plastic or other like material.
zz The distal end (16) of the shaft extension has a well (24) within it that is z3 configured to receive the end of a standard drill bit (2), such as any of those shown on z4 the right side of FIG. 4. The depth of this well is such that it can allow the bit to enter zs the well to a depth so that there is ample surface area of the well interior wall in zs contact with the drill bit to absorb with little deformation the larger torques applied z7 by a power drill. To aid in holding a drill bit, which is typically made of steel and is zs an iron containing material, in place within this well (24), the distal end (16) of the z9 shaft can be magnetized so that it will magnetically attract an iron containing drill bit.
3o If the shaft is of a magnetizable material, this can be accomplished by magnetizing 3i the shaft directly. If not, a suitably shaped magnet can be placed in proximity to the i shaft's distal end (16). Similarly, the tip end (14) of the shaft (10) can be magnetized z to aid in holding iron-containing screws or other anchors on the shaft's tip.
s The shaft of this embodiment of a screwdriver according to the present a invention has a tube-like screwguide (26) that encircles the shaft (10) in such a s manner that the shaft of the screwdriver (1) can rotate freely within this screwguide 6 (26) while the screwguide itself is held stationary. The screwguide (26) also can be 7 moved laterally on the shaft (10). This screwguide is used to guide screws into place s as the screwdriver (1) is powered by a drill.
9 To use this screwguide (26), one places a screw on the tip (14) of the shaft io (10) and then slides the screwguide forward to enclose the screw. One then places a i i hand on the outer surface of the screwguide (26) to hold it stationary, thereby iz stabilizing the position of both the screw and the screwdriver (1).
is When power it applied to the handle's distal end (16), the shaft (10) turns and i4 drives the screw forward as it is held in place by the screwguide (26) until it is fully is anchored in its desired location. This screwguide (26) is also seen to serve the safety i6 purpose of preventing a misaligned screw on the tip (14) of the screwdriver from m being thrown off line and possibly even launched sideways, so as to become a threat 1 s to those in the area, when a large amount of torque and a high rotation rate are applied i9 to the screw. If the tip end (14) of the shaft (10) has been magnetized, the choice of zo the material for the construction of the screwguide (26) will be made so that the zi screwguide is not attracted by the magnetic properties of the shaft's tip end (14).
zz To aide the further versatility of such a screwdriver, another preferred zs embodiment of the present invention consists of a screwdriver similar to that za described above, but having a tip end (14) that is configured so that it can as accommodate any one of a number of multiple ends or screw bits. For example, if the 26 tip end (14) has a hexagonal shaped well (27) in its tip, it can interchangeably z7 accommodate any of the screw drivers or drill bits (5) shown on the right hand side in za FIG. 4. To aid in holding such drivers in place, the tip end (14) would also be z9 magnetized. ' 3o To make it easy to keep up with various driver or drill bits (5), another si embodiment of the present invention has a handle which has slots (15) around the i perimeter of its front (17) face. These slots (15) are configured so as to accommodate z and allow one of the various driver bits to be inserted and stored within each of the s slots. See FIG. 6.
a In addition to performing as a screwdriver, this device can easily be made to s perform as a nut or other type of driver by configuring the tip (14) of the shaft (10) so 6 that it can mate with various types of nuts, bolts or sockets. Again, the tip can be magnetized to aide in holding an anchor on the tip. Some of the types of drivers (7) s that can be used with this device are shown on the right side of FIG. 5, while shown 9 on the left side of are the various bolts, nuts, sockets (6), etc. that can be inserted with io these drivers.
i i For various low torque applications, it may be desirable to configure these iz devices so that they consist not of a single shaft which extends all the way thorough i3 the handle, but to insert into the end surface (18) of the handle (12) a metal insert (28) is which has within it an especially configured, magnetized well (24) for receiving a ~s standard drill bit. See FIG. 7.
is It should also be noted, that for some specialized applications, it may be i7 desirable to configure these devices so that they have a male shaft adapter (30) that is extends from the handle's end surface (18) rather than have the well (24), or female i9 adapter, at the distal end (16) of the shaft (12). In such an embodiment, this adapter zo (30) would be configured so that it could be directly accommodated and fit within the zi chuck of a standard electric drill. See FIG. 8.
zz In still other applications, it may be desirable to configure the present z3 invention into another embodiment in which the shaft does not extends all the way za thorough the handle. This embodiments has an insert (32) which has a well (33) that zs contains an especially configured, male, pop-out adapter (34). See FIG. 9.
The insert zs (32) also has a spring mechanism (36) which is operable by an extension (38) that z7 extends to a location (40) on the outer surface of the handle (12) and serves to make zs the adapter (34) interchangeable between a first and a second position. In its first 29 position, this adapter (34) extends from the handle (12), and in its second position, 3o the adapter is retracted into the insert (32). In its first position, this adapter is easily 3i fitted within the chuck of an electric drill, while in its second or retracted position, the adapter does not interfere with a user who wishes to grip the device by its handle and z use it, without the aid of an electric drill, to install a screw anchor.
s Another preferred embodiment of a driver device (1) having multiple tip a interchangeable capability is shown in FIG. 10. It consists of a shaft (42) and a s handle (44). The shaft (42) has front (46) and rear (48) ends. Each of these has an 6 especially configured well (50), (52).
7 The rear end well (52), as before, is configured to receive the end of a s standard drill bit (2), such as any of those shown on the right side of FIG.
4. The 9 depth of this well (52) is such that it can allow the bit to enter the well to a depth so io that there is ample surface area of the well interior wall in contact with the drill bit so i i as to absorb with little deformation the larger torques applied by a power drill. To aid iz in holding a drill bit in place within this well (52), the rear end (48) of the shaft can is be magnetized so that it will magnetically attract an iron containing drill bit.
is The front end well (50) is configured to receive the rear end (56) of any one of is a number of interchangeable shaft extensions (54). Again, the depth and wall is thickness of this well (50) is chosen so as to accommodate the expected torque to be i7 applied by the device. Both the front (58) and the rear (56) ends of these extensions is (54) are configured in the form of a driver head which is to be used to drive a specific i9 type of screw or anchor, such as those shown in FIG. 4. These ends will preferably be zo magnetized to aid in holding iron-containing screws or other anchors on either of the zi extension's tips.
22 For higher torque applications, a portion of length of the shaft extension (54) 23 Can have one or more ribs (60). With such an extension, the front well (50) would z4 then be configured so as to have matching slots (62) to accommodate the ribs (60) so zs that the extension (54) can still fit within the front well (50).
zs For even more versatility, an embodiment of the present invention is provided z~ with a two piece shaft, front (66) and rear (68), and a clutching mechanism (70) in the zs handle (72) which enables the tip (74) of the front shaft (66) to be rotated in either a z9 forward, for inserting a screw anchor, or a reverse, for withdrawing a screw anchor, so mode of operation. The rear shaft (68) has a well (76) in its rear end so that it can be 3i driven by the insertion of the bit of an electric drill. The front portion of this rear i shaft has a connecting end (73) that connects with the clutching mechanism (70) 2 which also connects with the rear portion (75) of the front shaft (66). This 3 embodiment is also provided with the ability to fit multiple types of bits into a well 4 (78) that exists on the tip (74) of the front shaft. It has storage slots (80) on the front s face (82) of the handle (72) for storage of the various bits that can be used with the 6 device. See FIG. 11.
7 As to a further discussion of the manner of usage and operation of the present s invention, the same should be apparent from the above description.
Accordingly, no 9 further discussion relating to the manner of usage and operation will be provided.
io With respect to the above description then, it is to be realized that the n optimum dimensional relationships for the parts of the invention, to include iz variations in size, materials, shape, form, function and manner of operation, assembly i3 and use, are deemed readily apparent and obvious to one skilled in the art, and all i4 equivalent relationships to those illustrated in the drawings and described in the is specification are intended to be encompassed by the present invention.
i6 The foregoing is considered as illustrative only of the principles of the i7 invention. Further, since numerous modifications and changes will readily occur to is those skilled in the art, it is not desired to limit the invention to the exact construction i9 and operation shown and described, and accordingly, all suitable modifications and 2o equivalents may be resorted to, falling within the scope of the invention as hereinafter 2i set forth in the claims.
