13 Claims.

The invention relates generally to catches and more particularly to a catch for sheet-metal cabinets.

The general object of the invention is to provide a novel catch structure for the door of a sheet-metal cabinet, which is inexpensive to manufacture, and which is so constructed that the catch structure or parts thereof may be readily assembled on the door after the door is painted or finished, thus permitting the parts to be finished or painted differently from the door, without involving the care required if the assembly had to be made before finishing the door.

It is also an important object to provide a catch structure for the door of a sheet-metal cabinet, having the portions of the catch structure which are visible on the outer face of the door, including the manual operator, of such construction that they do not extend any substantial distance beyond the plane of the door, thus giving a pleasing appearance and providing a construction which will not readily be marred by being bumped.

Another object is to provide a novel catch structure for the door of a sheet-metal cabinet, which effectively holds the door closed, which is a spring type catch thus automatically locking the door by pushing it closed, and which is of simple construction.

Other objects and advantages will become apparent from the following description, taken in connection with the accompanying drawings, in which:

In the manufacture of sheet-metal cabinets such as so-called utility cabinets used in homes, it is necessary because of competition to keep the cost of such cabinets as low as possible. Thus the hardware that is placed on such cabinets must be of very inexpensive construction. Moreover, elaborate precautions cannot be taken to protect the cabinets in shipping because of the expense involved, and manufacturers have resorted merely to placing a paper bag o er the cabinets to protect them during such shipment. Thus any hardware on the cabinet which projects any substantial distance beyond the sides of the cabinet tends to cause the shipping envelope to be torn and the hardware to be damaged. It is therefore desirable to have all hardware placed substantially flush with the walls of the cabinet.

Since such cabinets are usually spray painted, it is desirable to install the hardware, or at least parts thereof, after the cabinet itself has been painted so that contrasting colors or finishes may be used. It is also desirable, particularly in the case of the catch used on cabinet doors, to make such catch so that it can be applied to the cabinet with a minimum of labor expense and Without requiring any special tools.

A typical construction for a cabinet of this character includes a door II! of flat sheet metal having its edge bent inwardly to provide a stiffening flange I I and then a portion bent at a right angle as at I2. The door frame, indicated at I3, is correspondingly bent inwardly to provide a flange I 4 paralleling flange I l on the door. The inner edge of the flange I4 is bent at a right angle, as at I5, to fit around the portion I2 on the door, and then is reversely bent upon itself as at I 6 to form a stiif rigid frame structure. Thus the flange I4 and the portions I5 and is form a structure in which the door snugly fits so that its plane is substantially flush with the plane of the door frame.

A catch structure embodying the features of the invention comprises generally a supporting member adapted to .be secured to the door, a latch member pivotally mounted on the supporting member, and a handle or operator for the latch member. In the form of the device shown in Figs. 1 to 5, inclusive, the supporting member and the latch member are adapted to be secured to the door prior to the painting thereof, and after such painting, the manual operator may be assembled therewith. Thus such structure permits the manual operator to be of a different 7 color or finish from that of the rest of the structure. The manual operator is adapted to be secured to the other parts in a very simple manner so that it may be done either at the factory before shipment, or the cabinet manufacturer may ship the manual operator detached from the cabinet so that the dealer or user may make such attachment.

In the form shown in Figs. 6 to 9, inclusive, the cabinet is adapted to be painted before any part of the catch structure is mounted thereon. Thus the supporting member may have a finish different from that of the cabinet, and also differing from the finish or color of the manual operator. In this case the catch structure as a whole is adapted to be secured to the cabinet by a very simple operation.

In the catch structure shown in Figs. 1 to 5, inclusive, the supporting member comprises a fiat plate 20 adapted to be secured to the rear face of the door I0, preferably by spot welding it thereto. The plate 20 is provided with a central inwardly dished portion 2| formed at its periphery to provide an outwardly projecting bead 22 adapted to fit within an aperture in the door Ill.

The supporting plate 20 extends toward the edge of the door and adjacent said edge is provided with means for pivotally supporting a latch member for movement in a plane perpendicular to the plane of the door. In the preferred form the means for supporting the latch member comprises a lug 23 formed by cutting a slit in the plate 20 and bending a portion at right angles to the plane of the door.

The latch member, indicated generally at 24, comprises a hook 25 adapted to engage the folded flange l6 of the door frame, and a leg 26 extending toward the lug 23 and pivotally secured thereto as by a rivet 21. The latch member 24 also has a portion 30 of generally arcuate form extending through an elongated slot 3| in the dished portion 2| of the supporting member, and an operator or handle, indicated generally at 32, is secured to the front end of the latch member. The catch is of the spring operated type and for this purpose a torsion spring 33 is wrapped around the pivot 21 and has one arm bearing against the rear face of the supporting member 20. The other arm of the torsion spring fits within a notch provided by cutting a pair of slits in the leg 26 of the latch member and bending a lug 34 formed by the slits at an angle, as shown in Figs. 4 and 5.

One of the features of the construction herein disclosed is to provide a latch member which is firmly held in its locked position when the door is closed, and yet which will be readily moved to its unlocked position to pass the door frame as the door is pushed closed. To this end it is desirable to have the pivot 21 and the-latch member as close to the edge of the door as possible. Thus, as will be noted in Fig. 2, the pivot pin 21 is located closely adjacent to the angle formed by the front plane of the door and the rearwardly extending flange thereof. With this arrangement, the latch member tends to remain in its latched position when the door is closed since the point of contact of the hook portion 25 of the latch member is in line with the pivotal axis thereof so that there is no camming action tending to move the latch member to its unlocked position. When the door is moved toward the closed position and the latch member is thereby automatically retracted by contact with the door frame, passage of the latch member past the door frame is facilitated by virtue of the fact that the hook portion is provided with a receding edge 35 which engages the flange l5 of the door frame to the right of the pivot 21 so that the latch member is readily cammed toward its retracted position.

As mentioned above, one of the features of the invention is to provide a catch structure, the different parts of which may be readily painted or finished in different colors. In the present form,

since the supporting member 20 is secured to the door ID as by welding, this portion of the catch structure is painted at the same time the door is painted. However, it is desirable to have the handle 32 of a different color or finish and to this end the handle is made separate from the latch member 24 and may be readily attached thereto in a simple but permanent nianner.

As shown in Figs. 4 and 5, the front end of the portion 39 of the latch member is made in the form of an offset tongue 35. The portion 30 is also punched as at 36 to provide a lug 31 which is initially bent at right angles to the latch member. The handle 32 in its preferred form comprises a backing plate 40 having a disk shaped cover plate 4| secured thereto as by turning the edges of the latter over the backing plate. Secured to the backing plate 40 and extending rearwardly therefrom through the slot 3| is an arcuate attaching member or shank 42 adapted to be secured in face to face relation with the portion 30 of the latch member. The shank 42 is offset as at 43, and at the offset is provided with an aperture 44 through which the tongue 35 is inserted. The shank 42 at its rear end is provided with a notch 45 within which the lug 31 fits. Adjacent the notch 45 but spaced inwardly therefrom is a slot 46 into which the 111g 31 is bent.

From the foregoing, it will be noted that the attaching member 42 and the portion 30 of the latch member are thus rigidly secured together in face to face relation. It will also be noted that such attachment may be made after the supporting plate is mounted on the door, merely by inserting the attaching member through the slot 3| into proper relation with the portion 30 and then bending the lug 31 into place. Such bending may be readily accomplished merely by a pair of pliers. This makes it possible for the manufacturer of the cabinet to readily assemble the parts after the cabinet is painted, or it permits the handle 32 to be shipped detached from the cabinet so that the dealer or user may readily assemble it in place.

The latch member 24 is so dimensioned and the slot 3| in the inwardly dished portion of the supporting member is so placed as to locate the handle 32 eccentrically of the dished portion 2|. Thus to release the latch and pull the door open, the user merely inserts his fingers in the dished portion 2| underneath the handle 32 and pulls outwardly thereon so that such ,pull first releases the latch and then moves the door open. The handle 32 is also located substantially flush with the front face of the door. Thus there is nothing protruding beyond the face of the door to interfere with handling the cabinet in shipping or to become damaged by being struck.

The modified form shown in Figs. 6 to 9, inclusive, is constructed so that the catch structure as a whole may be secured to the door after the cabinet is painted. To this end the supporting member comprises an inwardly dished portion 50 having its periphery reversely turned to provide a bead The aperture in the door is of sufli-' cient diameter to receive the dished portion 51! but of less diameter than the head 5! so that the edge thereof abuts against the front face of the door, as shown at the righthand side of Fig. 6. The supporting member also has a portion extending through the door to support a latch member. In the present instance such portion comprises a lip 52 extending from the edge of the bead 5| through a notch 53 out in the margin of the aperture in the door. The lip 52 is bent to lie against the inner face of the door and to pivotally support the latch member. The margin of the aperture in the door is also provided with a pair of notches 5% generally opposite the notch 53 through which lugs 55 extend. from the bead 5i. After the supporting plate is put into position within the aperture of the door, these lugs 55 are bent against the inner face, thus holding the supporting plate rigidly in position on the door.

The latch member in the present instance is of generally the same form as shown in Figs. 1 to 5 and extends through a slot 59 out in the dished portion 50, but has the handle or operator, here indicated at 56, directly secured thereto. In assembling the latch member to the supporting member, a small lateral notch 5'! is cut in the dished portion to permit the passage therethrough of the lug on the latch member leg which supports the torsion spring. To limit the inward movement of the latch member; a small boss 58 is pressed laterally from the latch member so that it will engage the inwardly dished portion 50 to limit the inward movement of the latch member.

From the foregoing description of the construction shown in Figs. 6 to 9, inclusive, it will be noted that since the supporting member may be readily assembled on the door merely by inserting it into the aperture therein and bending over the lugs 55, the catch may be mounted on the door after the cabinet is painted. This also permits the handle, the supporting member, and the cabinet all to be of different colors or finishes.
