14 Claims.

The .invention relates to a catch which may be employed for holding together two separable members. Examples of such devices to which the catch may be specially adapted are vthe main body and cover of compacts, vanity cases, cigarette cases and the like. It will be understood, of course, that the invention is not limited to such specicv uses.

A purpose of the present invention is to provide a catch which may be simple in its construction and sure and easy of operation. The catch may be resiliently held in engaging position and may be released by pressure. Preferably the construction is such that it is made of` simple, readily available materials by a few steps and with the use of a few simple tools. The catch is provided with supporting or attaching means which aresimple and sure in operation and easy to install. Preferably the supporting or attaching means may be closely associated with the operating means so that the appearance of the device to which the catch is attached may be interfered with as little as possible.

Preferably no particular internal construction is required of the device to which the catch is applied. To this end the catch and its supporting and operating mechanism may be entirely attached to one wall of thereceptacle and operate without interfering with the inside arrangement of the receptacle and without requiring any lining or the like to be inserted in the receptacle for cooperation with the catch. When desired the mechanism associated with the catch may be so arranged as to form a covering for the inside of one wall of the receptacle. The catch and its supporting mechanism without alteration of dimensions may be inserted into receptacles of various sizes.

Preferably the catch and its supporting mechanism may be securely mounted in the receptacle without welding, soldering, riveting or similar fastening means which have generally been found necessary in the past.

In the accompanying drawing embodimentsv of the invention are illustrated. Fig. 1 is a diagrammatic side or front elevation of a closed receptacle to which the catch has been applied. Fig'. 2 is a fragmentary plan view of Fig. 1 with the cover removed. Fig. 3 is a fragmentary section on a larger scale on the line 3-3 of Fig. 1. Fig. 4 is a perspective View of one form of resilientl catch supporting mechanism. Fig. 5 is a perspective View of one form of catch. Figs. 6

and 7 are fragmentary perspective views of other forms or constructions of the catch supporting mechanism. Figs. 8 and 9 are perspective views of cooperating members making another form of catch Supporting mechanism. Fig. 10 is a plan view of one form of side-member of a receptacle to which the catch may be applied. Fig. 11 is a perspective view of another form which the catch and its supporting mechanism may take. Fig. 12 is a section on the line |2|2 of Fig. 11. Fig.

13 is a section similar to Fig. 12 of a somewhat modified form of catch.

A receptacle is shown consisting of a cover member 20 and a bottom member 2| to which the catch is shown as applied. As illustrated particularly in Fig. 3 the top member 2U may have an engaging lug 22 which may be engaged by the usual projecting lip 23 of the Acatch member 2li.` The lip 23 may be disengaged from the lug 22 by pressing on the catch operating mem-- ber 25 which extends through an aperture 26 in the front wall of the lower portion of the receptacle. It will be understood that the lower portion 2| may be a cover and the portion 2D the receptacle itself. Obviously the catch may be employed to hold together any two members and the catch may be mounted in either of the cooperating members. Supporting the catch 24 as illustrated in Figs. 1, 2, 3, 4 and 5 is a resilient band preferably of some sort of spring metal. rThis consists of a back portion 21 against which rests the catch 2li. The back portion 21 is continued into

end members

28 and 29 which are bent inwardly toward the center of the back member 21 but leaving between their ends a recess large enough to receive the operating member 25. The

end members

28 and 29 have at their ends outwardly turned

lugs

30 and 3| which normally lie beside the ends of the operating member 25. lin the face of the member 2| the opening 26 is of suitable size to receive the operating member 25 and may have enlargements 32 to receive the

lugs

30 and 3|. The catch member 24 is assembled with its

resilient support

21, 28 and 29 and the assembled structureis associated with the member 2| by inserting the operating member 25 and the lugs 3i! and 3| through the aperture 26. The

lugs

30 and 3| may now be turned outwardly as indicated in Fig. 2 to grasp the wall 2| and hold the structure in position on the wall.' In this position the back portion 21 will engage the catch 24 and tend to force it into latching position. Pressure on the operating member 25 will cause the resilient supporting

member

21, 28, 29 to give and allow the lip 23 to be moved inwardly far enough to release the lug 22. The latch `and its operating member have been shown in conventional form. They may be of any suitable shape or form such as oval, circular and the like, the rectangular construction illustrated not being essential to the invention.

The length of the

member

21, 28 and 29 and the height thereof may be of any suitable dimensions. In some instances it may be convenient to have the member 21 substantially the length of the supporting wall of the member 2| as illustom of the aperture 25 is immaterial.

trated in Fig. 2 and the height of the member 21 may conveniently be substantially the height of the section 2l in which the latch is supported. There may be an advantage in this construction as thus the member 2l may make a smooth side Wall to the receptacle section 2l but this is not essential to the invention. rThe back member 21 is shown as of the same Width as the

members

28 and 29 but this is not essential as they. may be of any suitable Width. The latch and its supporting mechanism may be made of a standard form and be applied to receptacles of various dimensions whether or not the member 2l covers the entire adjacent wall.

It will be noted that the

members

28 and 29 lie closely adjacent the front Wall of the section 2l and the member 2l is separated slightly from them. 'I'his may be an advantageous construction depending somewhat upon the shape and size of the catch. There may be an advantage in eliminating wholly or partly this gap between the members 28 and. 29 and the member 21. One Way of accomplishing this is illustrated in Fig. 6 in which the member 2B is illustrated as lying substantially in Contact with the member 2l. In this instance the bend between 27 and 28, which is indicated by the numeral 33, is preferably not asharp bend but is curvilinear in outline. This may be desirable to avoid fracture or undue strain in the spring material. In Fig. 7 a similar result is accomplished by having the back member 2in flat and the iront member 28a flat, each being separate pieces. The members 2'!a and 28ix may be held together preferably toward their outer ends by any suitable means such as the rivet 33a illustrated.

In Figs. 8 and 9 is shown another arrangement in which the latch supporting mechanism consists of a back plate 3ft against which the catch may rest and which is provided with end lugs 35. The back member 3d is associated with a front membert which is provided with holes 3T. The member 34 will be of resilient material such as spring metal and the lugs 35 and the plate 36 may if desired be made of similar or any other suitable material. The plate 3% is provided with a central aperture 38 through which may be placed the operating member 25 for the latch 24. The plate 3ft may then be bent and the lugs 35 passed through the openings 37. This will hold the latch in place. Associated with the aperture 38 are lugs 30a and '3W at its ends. At the top and bottom oi the aperture 38 are indicated additional or alternative lugs 39 and fw. The assembled plates 34, 3e carrying the catch may then be associated with a plate 2ia of a section of a receptacle or the like such as illustrated in Fig. 10 in which the opening 26 is shown as provided With supplemental openings 32a at its ends and additional supplemental openings 321 at its top and bottom through which may pass the lugs 32a, 3ia, 39 and i9 and over which the lugs may be turned to hold the assembled structure in appropriate operative position. It is obvious that the position and number of the various lugs on the ends or top and bot- Any of the lugs desired may be omitted and the remaining lugs employed to hold the structure in proper position.

The catch 24 and the operating member25 may be made as a unit or they may be connected together in any suitable well knownmanner. In Figs. il .and l2 is illustrated a form in which the catch operating member and supportingmember maybe made of a single piece of metal. Thus the back member 2b of the supporting mechanism may have an integral rising portion 2lia on which may be formed the lip 23 of the catch. Opposite the lip 23 an extending portion of the member 21h may be turned at substantially right angles to the member 2'!b and turned back on itself as at 40, 4l. The end of the back member 2lb may be bent over on itself forming the front member 29a in which may be an aperture 42 Which may pass over the folded portion 40, 4| which thus becomes an operating member for the catch 24a. At the sides of the hole 42 may be formed lugs such vas v301 by which the catch and its supporting mechanism may be attached to the wall of the section 2|. In Fig. 1l it Will be noted that the lbackl member. 2lb ends Withthe .catch 24 and does. notI extend there-beyond, the resilient band being bent at one end only. This single end construction may be advantageous in some situations. It may save metaland allow ready, convenient support and. installation. A similar single end construction might be employed in connection with other forms of the catch supporting mechanismv illustrated.

In Fig. 13 is illustrated a form similar to Fig.-v 12 in which the catch. operating member consists of a single'member 40a the folded-back portion'M illustrated in Fig. l2 being omitted.

It will be noted that in the variousnconstructions illustrated the resilient member for `supporting thev catch is mounted at and throughv the hole through which passes the catch'operati-ng member.

solid and without its integrity broken or interfered with at any portion .other than the hole through which the operating member passes. No attachment is necessary at any other poi-nt. This not merely avoids holes in the wall but also climi# hates any necessity `for weldingv even, which in addition to its cost and difficultyof operation might interfere with the character of the..metal of the wall and make its proper ,decoration difficult.

It will be noted that the resilient supporting member is fastened at one offitsv ends through the hole and the catch rests against-.the'portion of the resilient-member.farthest removedfrom the attaching means along a linear line through the resilient mechanism. For instance it will be observedin Fig. 2 that thecatch 24 .rests against the member 21 at about-its middle. Pressure,

then, on the operating member 25 Will bring into play the entire resilience of the supporting member the tendency being not merely tolflex the mem-ber 21 but: also to flex the members-28 and 29 themselves. When desired the flexible member may be made relatively small but the 'elasticitydfue to the entire length of the membermay 4be employed.
