Jan. 12, 1965 G. RElTZEL BOX COVER SUPPORT Filed March 27 1963 INVENTOR.
GEO/3G RE/TZEL BY FIG. 5 a
Ar-ru vl-YS according to the invention is offered to This invention relates to a box cover support, and more particularly to an improved pivotal support for a box cover for facilitating release of the cover from its closed position. The boxand cover arrangement of the present invention may be used for practically any type of box United States Patent ferent' position of displacement of the cover relative to .155.225 H Patented Jan. 12, I955 FIG.5 is similar toFIG. 4, except that it shows a difthe box. I r
Referring to the drawings, FIG. 1 shows the upper por-' tion of a case 10, such'as a cigarette case, upon which a cover'or top 12 is supported. In order to hinge the cover 12 to the box 10, a pair of lugs 14, 16 extending from an edge of the box 10 and a pair of lugs 18, 20 extending from an edge of the cover 12 are provided, in spaced-apart relationship. The Iugs14, 16 on the box are disposed between the spaced-apart lugs 18, 20 on the cover 12. A
I 1 pin or shaft 22 slidably passed through the lugs hinges v the cover 12 to the box 10. The shaft 22 is maintained and is particularlyadaptable for use with a box used as I a carrying case for a package of cigarettes or as a jewelry I case.
It is a broad object of the invention to provide a novel and improved hinged box top or cover which is locked to the box by externally invisible locking, means and can be opened only by a mode of operation that is not apparent from the outside. Such concealed mechanism protects the contents of the box against pilfering by a person not familiar with the secret mode of operation, and also. has considerable entertainment value when a cigarette case a person with the suggestion to help himself. 7
A specific object of the invention is to..provide -a noveland improvedbox cover which can be conveniently locked and unlocked with one hand.
Another specific OlJjCCl'Of the invention is to provide a novel and improved box' cover which may be easily opened with one hand merely by sliding the cover in eitherone of two directions, and which may also be easily closed with one hand merely by pivoting the cover to its closed position. 1
Another specific object of the presentinvention is to provide a boxwith a hingedcover and a latch mechanism for the cover which is concealed from View when the cover is in a closed position, and: wherein the cover is sprung to the open position by sliding the cover to-one side relativetothebox. I v
' Another specific object is to provide a box witha hinged cover which may be sprung into the open position by pushing the cover parallel to itself in either one .of two directions. x I u Another specific object is to provide a box havinga simplified structure for pivotall'y supporting a cover such that the cover is automatically unlatched when it is slid to one side relative to the box.
Other objects and features of the invention will appear as thedescription of the particular physical embodiment selected to illustrate the invention progresses.
For a better understanding ,of the present invention,
to the left, as it is shown in FIG; 5.
reference should be had to the accompanying drawings,
otal support and latch structure of FIG. 1 with the cover in an open position;
FIG. 3 is an elevation in cross section of the box and cover of FIG. 1;
I FIGQ4 is a front view of the upper portion of the box of FIG. 1 with the cover, which is partly broken away,
in a closed position and displaced to one side of the box; and I 1 in position by providing means, such as enlarged heads, at each end of the shaft 22 which prevent the shaft 22 from slidingout of the lugs and also in reference to lugs 18, 20 once the hinge mechanism isassembled. The enlarged heads may be formed, for example, by peening over the ends of the shaft 22, as indicated by the numeral 24 in FIG. 2. One of the enlarged heads is, of course, made after the shaft 22 is inserted through the coaxial elongated openings of the lugs. The shaft may also be edly secured to one or both lugs 18 and 2d.
Carried on the shaft 22 between lugs 14, 18 and between lugs 16, 20 are coil springs 26 and 28 respectively. The ends of thesprings 26, 28 abut the sides of the respec- :tive lugs, and these springs are loosely mounted on shaft 22 so that they are 'free to be compressed and expanded as the distance between the respective lugs is decreased and increased. Since lugs 14, 16 are free to slide longi tudinally on'the' shaft, it is evident that with the abovedescribed construction, the cover 12 is free to move relative to the box 10 by sliding the cover 12 in a direction parallel to thelongitudinal axis of the shaft 22.
26 and 23 are matched, and the distances between thelugs 18, 14 and 16,20 are maintained substantially equal by the springs in the absence of an applied force F. Thus, in the absence of an applied force F, the cover will normally be maintained in an aligned position relative to the box such that the ends of the cover are coextensive with the ends of the box, as is best shown in'FIG. 2. In FIG. 2,
therefore, the springs. 26 and 28 are under slight compression, but the cover is maintained in an aligned position because the springs are matched.
Instead of applying a force F to shift the cover 12 to the right, the force F may be applied to shift the cover In this case, the spring 28 will be compressed as the lug 2'0 approaches the lug 16, and'the spring' 26 will be allowed to expand as the lug 18 moves-away from the lugs 14. 3
From the foregoingdescription, therefore, it'can be seen that the cover will'normally maintain an aligned position on the box 10, but may be shifted in either direction by applying a correspondingly directed force to the cover The slidable mounting of the cover is utilized to unlatch the cover from the box. The cover 12 is normally held in a closed position, such as is shown in FIG. 3, by a latch mechanism, which may comprise, for example, a hook 30 on the box 10 and a catch 32 on the cover 12. The hook 30 and ca'tch32 are in registry and engage one another when the cover-'12 isgenerally aligned with the box 10; The width of the hook 30 and catch 32 are such that when the cover 12 is slid in either direction, as described above, the catch 32 will slide out of engagement with the hook 30, and the cover 12 will be sprung into an open'position by a spring 34 carried on the shaft 22 between the spaced lugs 14 and 16. One end 36 of the coil spring 34 extends outwardly to engage the cover 12, while the 'otherend 38' extends outwardly to engage the box 10, so that the coil spring serves as a torsion spring tending to urge the cover 12 toward an open position, as shown in FIG..1 The end 38 of the coil spring '34 may be secured to the box, as shown in FIG. 3, by embedding it in thematerial forming the box. The coil spring 34 is maintained in its axial position on the shaft 22 between the two lugs 14 and 16 a the cover is shifted so that the shaft 22 slides through .the stationary box lugs 14 and 16 and the coils of the spring 34, while the end36 of the springs slides on a face of the cover 12. The end. 36 of the spring 34 may slide, for example, on the inside face of the cover as the latter is shifted.
1 Once the cover 12 has sprung open and the force F is removed, the cover will, in its open position, automatically resume its aligned position relative to..the. box lib-because the matched spring. 26 and 28 will re-equalize the distances between the lugs'14, 18 and 16, 20. The' coil spring 34 will maintain the cover in its open position.
While in its open and aligned position, the cover may be snapped shut merely by pivoting it to its closed position without Sliding the cover relative to the box, as was the case when the cover was unlatched; The normal resiliency of the materials'used in making the various parts of the box and cover will allow the catch 32 to override the hook to snap shutto a closed position, asshown in 1 FIG. 3. To facilitate closing of the cover, the hook 30' and catch 32 vmay be provided with inclined surfaces 40 and 42, respectively, which engage and slideion each other as the cover is snapped to a'closed position.
As is evident, the entire locking, mechanism is completely concealed by the rim of: the cover when the same isclosed.
The parts of the box and cover may be made of anyv suitable materials. The box, for example, may be made of plastic sheet material covered with leather, or other decorative material, while a metal border member 44,
' made of brass, for example, may be secured to the box along the'upper edges thereof, The border member 44 may have'an inverted U-shaped; cross section such that the upper edge of the box may be accommodated in the member 44, as is shown in FIG. 3, thereby retaining the upper edges of the plastic. sheet and decorative material, while at the same time. increasing the rigidity of the box structure. The sides of the; border member 44 may be pressed onto the material of the box which it accommodates to assure a good connection therebetween. The lugs 14, 16
may be formed integral withthe border member by initial- 1y; providing fiat extension pieces ofthe border. member i and then bending them to form elongated cylinders,"as
shown in the drawings.
The cover -12 may be made entirely of metal, for example, with a portion covered With decorative material to match the decorative material of the. box, or alternatively,
the cover to its open position. To close the box, the cover,
may readily be snapped shut also with the thumb.
The invention hereinabove described maybe varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible embodiments of the same; The invention, therefore, is not to be restricted to the precise detailsof the structure shown and described. 7
What is claimed is: 1 1
l. A case comprising a bottom part open at oneend and having a pair of cars extending from one edge of the bottom part at'the open end thereof and a'closure part for closing-the'bottom part and having a pair-of ears extending from a corresponding edge of the'closeure' part,
the two ears of one pair being disposed between'the two" ears of the other pair in alignment therewith and spaced therefrom, a pintle extending through said earsto provide a hinge connection between the two parts'allowing for relative displacement thereof in the-direction-of said positions and disengageable when the parts are displaced out of said position, and a case opening coil spring disposed between the two intermediate ears, said opening spring encompassing .th'epintle and'abutting against the" bottom partand the closure part to bias'the latter into anopenposition, whereby upon closing of .the closure part 'againstthe. action of said opening spring, said latch means maintain the closure part in its closed position, and upon displacement of the closure part in reference to the bottom part in the direction of the pintleagainst the action of said positioning spring, the latch 'meansarereleased and said opening spring opens said closure part. i
2. Al case as set forth'in claim 1, wherein said latch means comprise'a hook member anda catch member, one ofsaid members being connected to said closure part and the otherof said members being connected to said bottom closure part to pivot about said pintle to an open position.
