Summary of the invention The present invention contemplates an apparatus case having substantially equal rectangularly-shaped halves pivotally joined at one end and preferably by a flexible hinge. The front half is provided with a recess sized to receive a cover panel hingedly mounted internally of the case and on the rear half. The cover panel is adapted to slide in a slot adjacent the recess in the front half and is cammed by shoulder means adjacent the slot so that the panel with the case in the closed position lies in the recess'which may have an opening, screen or some like element which it is desirous to protect during storage and transport. When the case is opened the halves moved to their open position the cover panel is cammed and guided by and in the slot until a latch on the end of the cover panel engages the shoulder and/or shoulders defining the slot and thus engaged the panel acts as and provides the means for supporting the front engaged one-half so as to hold the two halves in a predetermined open position. When desired, there may be formed in the back half a pivot socket in which there is mounted a leg member, the inner end of the mounted leg member is retained in the socket by a spring and the leg member is shaped so as to engage stop means adjacent the socket, the stop means providing limits to the movement of the leg member.

Referring now to the drawings in detail and in which like parts are designated with the same reference number, the exemplified case assembly as seen in FIG. 1

includes a base half 10 of a generally rectangular construction and having a pair of sides 11 and 12, a top end 13 and a bottom end 14. A back wall 16 extends from and is joined to the sides 11 and 12 and ends 13 and 14. A lip or receiving shoulder 18 is formed on the front or engaging edges of sides 11 and 12 and top end 13. In the present instance a handle 20 is molded as a part of the base half 10 and, as shown, extends upwardly from top end 13. The bottom end 14 is provided with a cut-out 21 or relief formed in its front edge. Disposed at a predetermined distance from the cut-out and at a selected distance from each other are a plurality of rivet receiving holes 22 adapted to mate with like holes formed in a leg portion of a flexible hinge 24 whose U-shaped portion is sized so as to fit in the cut-out 21 in the bottom end 14.

A top half 25 of a length and width similar to the base half 10 is, as exemplified, formed with a front wall 26, a bottom end 27, a left side 28, a top end 29 and a right side 30 (end 29 and side 30 are not seen in FIG. 1 but may be seen in FIGS. 2, 3 and 4). In the bottom end 27 a cut-out 32 or relief is formed in its front edge. Disposed at a predetermined distance from the cut-out 32 are a plurality of rivet receiving holes 33 adapted to mate with like holes formed in the other leg portion of the flexible hinge 24. This cut-out 32 is sized so as to accept and retain the hinge 24. Formed in the upper or top portion of the front wall 26 is a recess 34 which is joined to the wall 26 on three sides and at the upper portion is formed with a slot 36 for a purpose to be described below. The base half 10 and the top half 25 are assembled in a hinged relationship by means of the flexible hinge 24 and rivets 37 mounted in holes 32 and 33. Rivets 37 are seen in FIGS. 2, 3 and 4 and exemplify only the preferred means of mounting the hinge and the top and base half. Other means such as adhesive can also be employed to attach the leg portions of the hinge to the top and bottom half, it only being necessary that the two halves be maintained in a predetermined pivotal relationship. The halves 10 and 25 are assembled so that the receiving shoulder 18 of the half 10 engages and seats the front edge of sides 28 and 30 and top end 29.

It is to be noted that the interior surface of the back wall 16 of the base half 10 is shown with a molded frame 38 upon and within which may be mounted apparatus not shown. The upper or left hand portion of this frame, as seen in FIG. 1, is adapted to receive a U-bracket 40 which may be attached to the frame by means of screws 42 as seen in FIG. 4. In the extremities of the upwardly extending ear portions of the bracket 40 there are formed a pair of aligned pivot holes 43 which are adapted to receive and retain inwardly extending pins 44 which are mounted in ears 45 extending from and as a part of a cover panel 46. In the opposite end of panel 46 there is formed an engaging tongue 48 which will be more fully described below. Panel 46 is sized so as to lie within the recess 34.

Referring now to the FIGS. 2 through and partly to FIG. 1, it is to be noted that the upper or left portion of the frame 38 has a molded portion adapted to receive and retain a leg 50. This leg has a straight lower portion 51 and a T-shaped upper portion 52 bent at an angle thereto with the lateral extending portions of the T adapted to rest in a V-receiving groove 54 molded in each side of the raised end portion of the frame 38. Intermediate these sides and extending between each of these' sides is a forward sloped shoulder member 56 and a rear shoulder member 58. These members are spaced so as to provide a passageway for the passing therethrough of the lower leg portion 51 of the leg 50. As reduced to practice, the outer surface of the sloped shoulder member 56 has this outer surface of the portion adjacent the passageway formed to provide a fortyfive degree inward and upward slope. In like manner, the outer surface of the shoulder member 58 has this outer surface of the portion adjacent the passageway formed to provide a forty-five degree inward and upward slope. A flat spring 60 is sized so as to be retained by shoulders 61 and 62 which, as exemplified, are formed by providing shut-offs from the outer or bottom side of the back wall 16. Spring 60 when mounted so as to be engaged by the shoulders 61 and 62, is adapted to engage the upper end of the T-shaped portion 52 of leg 50. A slide clip 63 is slidably mounted on and is retained by a suitably formed guideway 64 on the base half 10. This slide clip is adapted to engage a guideway tongue 65 carried by the top half 25.

Referring now to FIGS. 6 through 12, there is shown an alternate embodiment of a latch means molded in the case halves in which the latch includes a latch tongue molded on one half and a latch clasp is molded on a mating portion of the other half. In particular in FIGS. 6 through 9, a half 70 is provided which may, except for the latch, be exactly like half 10 or half 25. This half 70 is formed with a back wall 71 connected to a top end 72 having a recessed lip 73 formed in its outer edge. Intermediate the ends of the lip 73 there is formed a tongue 74 which is provided with a front surface 75 which is sloped upwardly and rearwardly until it reaches a determined point above the normal top surface of end 72. An upper slide surface on a stop block 76 continues to a shoulder or engaging surface 77 which extends from the top surface downwardly to the outer surface of end 72. In the present embodiment it is desirable to make the tongue deflectable out of the plane of the end 72 hence there is accordingly provided reliefs 78 and 79 at each end of the tongue 74. As reduced to practice, the half 70 is made of molded high-impact, high-heat resistant polystyrene and the tongue 74 is seven-eighths of an inch long with the reliefs 78 and 79 each being onesixteenth inch wide. The tongue at the point of juncture with end 72 as well as the general thickness of end 72 is about three-thirty seconds inch thick with the stop block portion 76 extending above the plane of end 72 for a distance of about five sixty-fourths inch. The reliefs 78 and 79 are sized so as to have the portion of the tongue extending forwardly of the connection to end 72 being of a distance of about one-quarter inch.

A clasp portion 80 is molded on the other or second half 81 which is addition to the back wall 82 and end 83 has a decorative retaining or receiving strip 84. This half 81, except for the latch change, may be exactly like the other half 10 or half 25 described above. On the underside of strip 84 there may be formed a receiving recess 58 sized so as to receive and retain lip 73. Intermediate the ends of the strip 84 is clasp portion 80 having a front slope 86 extending upwardly and outwardly to a determined point. An upper portion 87 extends rearwardly to about the rear edge of strip 84. A hollow or recess 88 formed by a shut-off extending inwardly from the rear of portion 80 provides a bar means for receiving and retaining tongue 74. A shoulder 90 formed at the front of the recess 88 is shaped so as to lie adjacent and engage shoulder 77 on the tongue 74. As with the tongue, it is desirable to provide means whereby the front portion of clasp 80 is deflectable upwardly so as to provide an easier means for the sliding of the bar 89 over the stop block 76. Shut-offs 91 and 92, as exemplified, extend inwardly from a point adjacent the outer edge of strip 84 and to a point about at the rear of recess 85. These shut-offs extend upwardly until their outer edges just meet the upper surface of strip 84. As reduced to practice, the half 81 is made of polystyrene in the manner of half 70 and back wall 82 and end 83 is about three thirty-seconds of an inch thick. Shut-offs 91 and 92 are made about one-sixteenth inches wide and about five-sixteenths deep and with strip 84 about three thirty-seconds inches thick the shut-offs will be of a like height. The recess 88 is made about one inch wide and at the formation of shoulder 90 is about three thirty-seconds thick so that shoulder 90 is about one sixty-fourth inches longer than stop block shoulder 77. The overall height of clasp 80 is about three-sixteenths inches and the length is about one and one-quarters inches while the width of the clasp is about thirteen-sixteenths inches at the bottom. .With the shut-offs 91 and 92 disposed so their upper outer edges coincide with the line forming the joining of clasp 80 and strip 84 the coinciding lines will provide a separation of clasp 80 and end 83 for that portion defined by shut-offs 91 and 92. The depth of the shutoffs can be lengthened or shortened and the width increased or decreased so as to provide a determined amount of attachment of the clasp to the half end to provide the desired amount of stiffness to the action of the clasp.

Assembly and use The assembly of the base of the apparatus case is made by first mounting the leg 50 in position. As seen in FIGS.

1 and the leg 50 has its straight portion 51 brought through the passageway formed between shoulders 56 and 58 and with the bent T-shaped portion 52 inclined toward the bottom end 14. The leg 50 is advanced in the passageway until the lateral extending portions of the T engage and rest in each of the V-grooves 54. One end of the flat spring 60 is then brought under the shoulder 62 and through relief 66 whence the other end of the spring is able to be deflected downwardly toward shoulder 56 and after this spring end is deflected below the level of the shoulder 61 in the spring is moved toward and under the shoulder 61 until the spring is adjacent or is stopped by the wall portion 67 whereupon the spring is released with this one end of the spring now being retained by shoulder 61 and the other end being retained by shoulder 62. Thespring bowed by being bent from a flat plane is now biased so as to urge the leg into the V-groove 54. When so biased and the straight portion 51 of the leg is swung within the limits of shoulders 56 and 58 the upper end of portion 52 is cammed by the spring toward either the sloped shoulder 56 or 58. The cammed leg when re-- leased thus is urged into an open or closed position. As seen in FIG. 4, a recess 68 is formed in the back wall 16 and is sized so as to receive the straight portion 51 as it is moved toward and to wall 16. In FIGS. 2 and 3 we see the leg 50 with the straight portion 51 moved into the closed position. With the spring 60 engaging the T-end 52 this end is urged into and is maintained in the closed position by means of the spring 60 and the shoulder 58. To move the leg 50 to the open position of FIG. 4 the end of the straight portion 51 is grasped and, asindicated by the phantom line and arrows, the leg is swung until the T-shaped end 52 engages the sloped wall 56 (FIG. 5) whereupon the straight portion 51 is substantially at right angles to the back wall 16 and is in the open or support position and the leg is maintained in this position by spring 60 and wall 56.

After the leg 50 and spring 60 are assembled as above, the U-bracket 40 may be mounted on frame 38 by means of screws 42 whereupon the cover panel 46 may be mounted on the U-bracket. The upstanding legs of the U-bracket are caused to be sprung toward one another an amount sufiicient for the pins 44 to be inserted in the pivot holes 43 in the bracket. Upon insertion of the pins, the legs of the U-bracket are allowed to spring back to their normal position and the cover panel is now pivotally mounted to the base.

The flexible hinge 24 is attached to both the base half and the top half 25 by means of rivets 37 and after assembly the halves may be moved from the closed position of FIG. 3 to an open position of more than ninety degrees. To provide a determined limit to this opening swing movement the novel cover panel 46 is used. In the apparatus case as reduced to practice, there is provided a viewing screen 69 which may be adhesively mounted to the recess shoulder 34 formed in the front wall 26. Other means of attachment such as screws, rivets or staples may be used to attach screen 69 or the like to the shoulder 34. It is not even necessary that a screen 69 be provided as it is contemplated that the opening occupied by the screen 69 maybe used for other purposes in which it is desired that the opening be covered when the case is closed and open when the case is erected and opened as in FIG. 4. For this purpose'the cover panel 46 which is pivotally mounted on bracket 40 is used as a safety cover. The engaging tongue 48 of the panel is bent or molded so as to normally be slightly out of the plane of the panel 46. To insert the panel 46 into the desired relationship with the top half 25, the free end of the panel 46 is brought to the slot 36 and the tongue 48 is moved upwardly into the plane of the panel and the panel is brought through the slot in the top half 25 and after passing the slot the tongue is released. The case may now be closed to the position shown in FIG. 3. In the process of closing the case a shoulder 70 formed adjacent the slot engages the outer surface of the cover panel and acts as a cam to urge and maintain this cover panel 46 in the closed position wherein'it is caused to lie in and against the shouldered recess 34. It is also to be noted that asthe case is opened the panel 46 is cammed upwardly and outwardly by means of the right-hand edge of the slot 36 as viewed in FIG. 2. As seen in FIG. 2 the top half is shown as being about one-half open and the hinged panel 46 ashaving been swung to a nearly perpendicular position in respect to the front wall 26 of the top half 25. As the top half 25 continues to swing outwardly approaching the position of FIG. 4, the slot 36 guides the panel 46 until the tongue 48 reaches the recess shoulder 34 whereupon the innercam surface 71 on the tongue engages the shoulder 34 and the tongue is cammed upwardly an amount sufficient for the tongue to enter the slot 36. When the tongue moves to a point over the recess shoulder 34 the tongue by means of its residual bias moves downwardly into its normal position whereupon the outer stop block 72 on the tongue engages the outer surface of the shoulder 34 stopping the movement position'on a support surface indicated as by line 74; To close the case, the tongue 48 is lifted to disengage the' abutment surface'of cam 71 from shoulder 34 and the above process is reversed.

The case is normally retained in a closed position by means of a slide 63 moving on a guideway 64 formed on the base half 10 and engaging a guideway tongue 65 on.

the top half 25, the slide being of sufficient length to engage, at the lock position, both the guideway and guideway tongue and maintain the two portions in alignment. Other lock means such as a snap or latch can be used instead of the guideway means exemplified and described above.

The molded catch shown in FIGS. 6 through 12 and described above has both its members predisposed on their respective halves so that when the case is assembled the bringing fully together of the two halves results in an automatic locking of the two halves. The tongue 74 as it is brought into engagement with the clasp portion has the slope surface 75 engaging the front slope 86 sothat tongue 74 is deflected downwardly and clasp portion 80 is deflected upwardly. The total of the deflections being suflicient for the stop block 76 and the bar means 89 to pass each other'whereby the residual bias in each connecting portion is suflicient to urge the tongue 74 and clasp portion 80 to their normal positions shown in FIG. 9. To open the catch and the halves, the clasp portion 80 is grasped at the slope 86 and is urged upwardly by manipulation so as to cause the shoulder surfaces 77 and 90 to slide on each other until they become disengaged. It is to be noted that the extent of top end 72 and end 83 is such that their thickness renders them slightly defiectable hence any difiiculty in the disengagement of the latch is reduced by the ability to harmlessly and slightly deflect the ends 72 and 83 as the separation manipulation is made.

The terms up, down, top, bottom, right, left and similar terms are applicable to the apparatus as described in conjunction with the accompanying drawings and such terms are merely for the purpose of description and do not necessarily apply to a position in which the case may be constructed or used.

While this invention has been described in detail with respect to a preferred embodiment and an alternate latching means, it will be understood by those skilled in the art that various modifications may be made without departing from the spirit and scope of the invention, and it is intended to cover all such changes and modifications in the appended claims.

An apparatus case having halves hinged at one portion so that the case may be opened in a predetermined manner to expose those components mounted in the case so as to use and View said components, and when closed the halves of the case are adapted to shield and protect the components therein, said case comprising (1) a first half of generally rectangular construction having sides, ends and a wall extending from and connected to the sides and ends, (2) a second half of generally rectangular construction having sides, ends and a Wall extending from and connected to the sides and ends, the second half sized so as to mate with the first half when the halves are moved into a face-to-face relationship with each other, (3) a receiving shoulder formed on one of the halves and providing means for receiving, guiding and retaining the outer edges of the mating other half, (4) a hinge attached to one end of each of the halves and providing means for retaining said halves in a predetermined pivotal relationship to each other, (5) a recess formed in the wall of the first half, the recess being of a selected size and depth, (6) a cover plate hingedly mounted on the second half and movable therewith the cover plate adapted to slide in said slot, (7) shouldered sides defining the sides of the slot, a first shoulder providing a slide surface for the inner surface of the cover plate when the cover plate is in said slot, the second shoulder shaped and sized so that as the halves of the case are moved toward the closed position said second shoulder engages the outer surface of the cover panel and while engaging the cover panel acts as a cam to move the cover panel toward the first half so that as the halves are brought to the closed position this second shoulder engages the outer surface and cams the cover panel into the recess, (8) an engaging tongue formed on the unhinged end of the cover plate, the tongue deflectable in and out of the plane of the cover, the tongue having a residual bias adapted to urge and maintain the tongue out of the plane of the plate, (9) a protuberance formed on the tongue and having on its side disposed toward the hinged end of the cover plate a sloped cam surface providing a cam means and on its other side the protuberance has an abutment surface, (10) a stop block on the tongue, the block being disposed at a predetermined distance from the abutment surface so that when the cover plate is moved outwardly through the slot the camming surface of the protuberance is caused to engage the shouldered side of the slot to cam the tongue into the plane of the plate and as the protuberance passes the shouldered side the tongue, urged by its bias, moves toward the shouldered side so as to engage the shouldered side between the abutment surface and stop block whereupon the cover plate becomes fixed in relation to the first half and in this fixed position provides a support leg whereby the halves of the case in this open position are disposed in a preselected spaced relationship to each other, and (11) a means for latching the halves of the case so that in a latched and closed position the halves are maintained in a fixed position with their ends and sides in a face-toface relationship and means for releasing the latch so as to allow the halves to be pivotally moved to the open position.

14. An apparatus case as in claim 13 in which the second half of the case has mounted therein a leg movable in a pair of receiving grooves disposed above the wall in the second half, the leg having a straight lower portion and a T-sha-ped upper portion bent at a determined angle to the straight lower portion, the T-portion having a pair of lateral extending portions sized so as to lie in and be pivotally movable and retained in said receiving grooves, and in which, intermediate the receiving grooves, there is formed a forward shoulder member and a rear shoulder member with said shoulder members being spaced so as to provide a passageway for the retention and passing therethrough of the straight portion of the leg, the outer surface of the forward and rear shoulder members being sized, shaped and spaced so as to provide preselected stop positions for the open and closed limits of the movement of the leg, and a flat spring adapted to lie in and be retained by seating means provided in the second half, the spring as it is mounted, engaging an end of the leg and being bowed thereby so as to provide a bias to urge the lateral portions of the leg into the receiving groove and to cam the leg into the open and closed limits of operation.

15. An apparatus case as in claim 14 in which the forward and rear shoulder members adjacent the leg passageway have their portions adjacent the passageway formed with sloped surfaces adapted to engage the T shaped upper portion of the leg as it is moved to its limits of operation and in which the second half has its outer wall surface formed with a recess portion adapted to receive and retain the straight portion of the leg when the leg is moved to the closed position.

16. An apparatus case as in claim 15 in which the recess formed in the Wall of the first half is of rectangular shape and with the slot adjacent the recess being on the side of the recess that is opposite the hinged end, and in which the means for latching the halves of the case is a slide clip slidably mounted on and retained on a guideway provided on one of the halves and with the clip adapted to slide into engagement with and retain a guideway tongue provided on the other half, the slide clip and tongue, when in engagement, providing a means for retaining the halves of the case in a closed position and when the slide clip is moved into disengagement the halves are free to be swung to the open position.

17. An apparatus case as in claim 15 in which the means for latching the halves of the case includes a tongue formed on and attached to an end of one of the halves of the case, the attached portion being at only the longitudinal inner edge thereof and being sized and shaped so that the material forming this attaching portion is disposed to provide a bias whereby the tongue may be urged by an applied force to move from its normal plane and by this bias the tongue is caused to return to its normal plane when the force is removed, said tongue having a stop block portion sized and shaped so as to provide a sloped camming means and a shoulder portion, and in which on the other half of the case there is a clasp portion formed and disposed so as to engage the tongue when the halves are brought toward and into a closed relationship, the clasp portion being attached to an end of this half of the case so that the material forming the attaching portion is sized and shaped to provide a bias whereby the clasp portion may be urged by an applied force from its normal plane and by this bias the clasp portion is caused to return to its normal plane when the applied force is removed, said clasp portion having a slope engaging portion adapted to engage the sloped camrning means of the tongue and as the two halves are moved toward each other the engagement of the tongue and clasp portion cause a deflection of at least one of the engaging members and against the residual bias in the tongue and clasp portions so that the stop block and bar means are moved from their normal plane an amount sufficient for them to pass each other so that when the halves are moved into their full closed position the bias in the attaching portion of the deflected member urges the member to a position whereby the 12 bar means of the clasp portion is adjacent the shoulder of the tongue whereupon said latching means is in the closed position.
