3 Claims.

This invention pertains to catches adapted for use on metal furniture and the like for releasably holding the doors of cabinets, such as kitchen cabinets, bathroom cabinets and the like, in closed position.

Catches of this character are designed to be mounted in an opening formed in a metal wall of a door frame or cabinet face, and in many installationsV the cabinet structure is such that the depth inside the cabinet wall for the reception of the catch is quite restricted.

One of the purposes of my present invention i is to provide a catch of minimum longitudinal or depth dimensions so as to be capable of being mounted in cabinets or the like which are restricted in the depth of space available for such catches.

Another purpose of my invention is to provide a catch in which the holding jaws will be disposed entirely back of the face of the cabinet wall or frame, so that no portion of the jaws projects outwardly beyond the plane of the wall face.

A further feature of my invention resides in the structure of the clamping jaws which are so shaped and proportioned as to present a closure or barrier across the opening in which the catch is mounted, so that the opening appears to be entirely closed by the catch structure and the entrance of dust, dirt or other particles through the opening into the cabinetl is to a large degree prevented by such closure.

Another object of Vmy invention is to provide a` catch which is simple in construction, which can be easily manufactured, readily assembled and which can be mounted in operative position in a wall opening by simply projecting it through such opening to a point where it becomes automatically locked in position.

For the purpose of facilitating an understanding of my invention, I have illustrated on the accompanying drawings a preferred embodiment thereof.

Referring to the drawing,

Fig. 1 is a fragmental perspective view of a Fig. 4 is an elevation looking toward the right on the plane indicated by the line 4 4 in Fig. 3;

Fig. 5 is a sectional view on the line 5--5 of Fig. 3;

Fig. 6 is an elevation of the-catch inthe initial 2 Y stage of being mounted in the cabinet wall; and

Fig. 7 is a perspective view of one of the clamping jaws.

Referring to the drawing more in detail, reference character 8 indicates generally the door frame or the surrounding walls of a door opening in a sheet metal cabinet such as a kitchen cabinet or other storage cabinet, and 9 indicates the door of hollow sheet metal construction adapted to close the door opening. A strike II mounted on the inner face of the .door is adapted to project inwardly through the opposed cabinet wall in position to be engaged and held by my novel catch.

The catch consists, generally speaking, of a sheet metal body, a pair of sheet metal clamping and holding jaws, a pintle upon which said jaws are pivotally mounted, a spring by which said jaws are yieldably biased into holding and clamping position, and means whereby the body will be automatically locked in mounted position upon being projected into a suitably shaped opening in the cabinet wall.

The body of the catch, which is struck out from a sheet of metal possessing substantial resiliency, comprises a base I2 and a pair of side walls I3 and Id formed integrally with the base, so as to provide a body of substantially channel shape. The margins of the free edges of the side walls of the channel are bent outwardly in opposite directions to form the anges I5 and I6 which serve as abutments to limit the projection of the body through an opening in the wall in which the catch is mounted. The opening il in the wall 8 is preferably, as shown in the drawing, substantially rectangular in shape and of a size to permit the insertion of the body of the catch therethrough until further movement is obstructed by the abutment anges I5 and I6 previously described.

The side walls I3 and I4 are slitted to provide the tangs I8 and I9, respectively, which are normally, by reason of their resiliency, biased outwardly into the position illustrated in Fig. 5, from which it will be observed that when the catch body has been inserted through the opening Il in the wall 8 as far as is permitted by the abutment ilanges I5 and I6, the ends of the tangs I8 and I9 will at such time have passed through the opening Il and snapped outwardly into the position illustrated in Fig. 5 where their ends engage the inner face of the wall 8 and hold the body against withdrawal from the opening. An intermediate position of the parts during the mounting of the catch is shown in Fig. 6, from Figs. l and 2.

which it will be apparent that the only labor involved in the mounting is that reciuired to insert the body through the wall opening until such movement is limited by the flanges I5 and I6, in which position the body will be automatically locked against displacement by the tangs I8 and I9. The walls themselves diverge toward their outer end to snugly engage the sides of the Wall opening and thereby prevent rattling of the catch in the opening.

A pintle 2I extends between the side walls t3y and I4 of the body and upon this pintle there is pivotally mounted a pair of clamping and holding jaws indicated generally by reference characters 22 and 23. Each of these jaws is struck from sheet metal shaped to provide a U-shaped holding portion, the curved base 2li oi jaw 22 being adapted to perform the holding' function and the end portions of the inner leg being bent inwardly to provide a pair of disc-like arms 25 journaled upon the pintle 2|. There is one of these bearing portions at each end of the jaw, and these portions are arranged upon the pintle in the manner disclosed in Figs. 5 and 6. The other jaw 23 is similarly shaped and mounted through the disc-like arms 26 upon the pintle 2I in 0pposed relation to the jaw 22'. A spring 2 mounted upon the pintle has its ends engaged with the respective jaws 22 and 23, as best illustrated in Fig. 3, to bias the clamping portions of the jaws e ,Figs l and 2, and they are substantially centered for the reception of the strike between them by engagement of the shoulders 3@ and Bil" with the base i2 of the frame.

For the purpose of substantially closing the opening I'I in the cabinet wall the outer leg of the U of each jaw is of surficient length to extend .slightly beyond the sides oi the opening i'I when the jaws are in closed position, as illustrated in The outer leg 23 of jaw 22v and the corresponding leg 29 of jaw 2:3, therefore, .serve to form a closure for' the wall opening and prevent the entrance of dirt and foreign particles into the cabinet and at the same time, since they lie inside the plane of the outer face of the wall, no projecting ends are visible, the smooth ycontour thus presented contributing substantially to the smooth and finished appearance of the catch presented to the eye when in mounted position.

It should be apparent from the foregoing that I have provided a catch in which the portions of the clamping jaws engaged by the spring are disposed outwardly from rather than inwardly with respect to the pintle upon which the jaws are pivoted, thus decreasing the depth of the catch over those constructions in which the jaws project a substantial distance inwardly beyond the pintle. The catch is, therefore, of minimum .length and is capable of use in constructions wherein the space available for such a catch is very limited.

It-will also be apparent that the holding jaws of my improved catch are so constructed that they do not project outwardly beyond the body of the catch or outwardly beyond the wall in which the catch is mounted. Furthermore, these jaws are proportioned to substantially close the opening in the wall and prevent the entrance of foreign matter into the cabinet, as Well as presenting a smooth and attractive appearance on the face of the cabinet. The catch is of simple construction, consisting merely of a body, a pintle, a spring and a pair of jaws, and the whole assembly may be economically manufactured and Very quickly mounted in a cabinet wall by simply inserting it in. an. opening oi suitable size formed therein.

The structural details illustrated and described may obviously be varied within considerable limits without exceeding the scope of my invention as described in the following claims.

I claim:
