6 Claims.

This invention relates to a mounting panel and fastener assembly for releasably mounting handles or other articles.

An object of this invention is the provision of novel mounting panel and fastener assembly by means of which a handle or other article may be quickly attached to or removed from the mounting panel with simple movements.

Another object of the invention is the provision of handle mounting means that is simple, that insures that a handle is positively maintained in a preselected relation with a panel when it is attached thereto, that is rugged, that requires a minimum of maintenance and that is relatively inexpensive to manufacture.

Another object of the invention is the provision of handle mounting means of the above character wherein a handle may be readily attached to and detached from one side of a door in the field as well as in the factory, and that does not require manipulation of threaded parts to efi'ect attachment of or removal of the handie from a door.

Other objects and advantages of the invention will become apparent from the following detailed description taken in connection with the accompanying drawings, in which- Figure 1 is a fragmentary perspective view showing a handle in a position to be attached to a door;

Fig. 2 is a perspective view of the back of the front panel of the door showing the construction of a leaf spring for holding the handle on the door;

Figs. 3 and 4 are sectional views showing different relative positions of the handle and the leaf spring as the handle is being attached to the door; and

-Figs. 5 and 6, similar to Figs. 2 and 4, show a modification of the invention.

Referring now to the drawings the invention is shown embodied in a handle and mounting therefor for use on an oven door |2 for a gas range or the like, not shown. It will be apparent however to those skilled in the art that the above construction may be used on many other types of equipment. In general, the oven door l2 includes an outer panel l3 and an inner panel M in spaced relation to the outer panel. The outer panel |3 preferably has its outer edges deformed to define a peripheral flange l8 receiving and supporting the inner panel l4. Suitable insulation I! is disposed betweenthe panels l4 and I3.

One aspect of the invention is the provision of a novel means for mounting a, handle H! on the door |2 so that it may be quickly and readily attached to or removed from the door I2 with a minimum of eifort and manipulation of parts. For this purpose the outer panel I3 is formed with spaced keyhole slots I3, each having an enlarged circular portion 2| and an elongated narrow portion 22 in communication with the circular portion. As shown in Figure 1 the elongated portions 22 extend outwardly from the same side of the circular portions 2| in a horizontal direction. The handle |8 may be of any suitable shape. In this instance the handle has a face 23 shaped to be flush with the outer surface of the panel I3 and a pair of screws 24 extending outwardly from the face 23 on opposite ends of the handle and spaced apart the same distance as the enlarged portions 2| of the keyhole slots. Each screw 24 is of such configuration that the head 26 may be inserted through the enlarged portion 2| of the keyhole slot l9 and the shank 21 of the screw may be received in the narrow portion 22 of the keyhole slot IS.

A leaf spring 28 is mounted in a cantilever manner at the rear of the panel l3 as best shown in Fig. 3 adjacent each keyhole slot l9. Each spring comprises a mounting portion 29, a bridging portion 3|, a central portion 32 and a free end portion 33. The bridging portion 29 is shaped to lie against the bottom wall 34 of a recess for the head of a screw 36 extending through one end of the slot 22 to secure the spring 28 to the panel l3. As shown, the mounting portion 29 has a hole for receiving the screw 36, defined in part by a pair of diametrically opposed tabs 3! deformed outwardly from the plane of the mounting portion 29. The tabs 31 are shaped to define a threaded connection to be ngaged by the screw 36. The central portion 28 of the leaf spring is spaced from the back of the panel l3 and the mounting portion 29 and is attached to the free end portion 33 and to the mounting portion 29 by the bridging portion 3|. Preferably the part of the central portion 32 adjacent the free end portion 33 is spaced farther from the panel than the part of the central portion adjacent the bridging portion 3|. Thus, as shown in Fig. 3, the central portion 32 is inclined outwardly from and at a relatively small angle to the back of the panel. The free end portion 33 is inclined from the central portion toward the back of the panel and its extreme end 35 terminates adjacent one side of the enlarged portion 2|. The central portion 32 and the free end portion 33 are formed with an elongated slot 38 extending lengthwise of the leaf spring and opening on the end of the free end portion 33. The shape of the leaf spring 28 is such that when the leaf spring is secured to the back of the panel the slot 38 is in registration with the slot 22. A tang M on the leaf spring is shaped to be inserted in the slot 22 to prevent rotation of the leaf spring and to assure alinement of the slot 38 with the elongated narrow portion 22 of the keyhole slot 19.

The handle 18 may be readily attached to the door l2. Thus, to attach the handle, the handle is brought into position such that the screws 24 are inserted in the enlarged portions 2| of the keyhole slots 19 on the panel [3. After both screws 24 have been inserted in the keyhole slots the handle :3 is moved laterally in the direction of the elongated narrow portions 22 of the slots. As the handle it is moved, as described, the shanks 21 of the screws 24 are received in the elongated portions 22 of the keyhole slots 19 and the heads 26 of the screws 24 engage the inclined free end portions 33. Lateral movement of the handle [8 is continued until the heads 26 of the screws 24 engage the central portions 32 of the leaf springs as shown in Fig. 3. During the lateral movement of the handle the inclined surfaces 33 serve as cams or guides to guide the heads or shoulders 26 to their proper location. As the handle moves from the position shown in Fig. 3 to the position shown in Fig. 4 each leaf spring 28 is stressed so that it tends to urge the heads 25 of the screws 24 away from the back of the panel and to urge the handle into tight engagement with the door i2. Because the part of the central portion 32 adjacent the free end portion 33 is spaced farther away from the back of the panel than the part of the central portion 3?. adjacent the bridging portion 3|, the interconnection between the central portion and the free end portion in effect defines a shoulder that must be cleared before the heads 26 can seat on the central portion 32. This shape of the central portion tends to lock the screw heads 26 in position on the central portions 32.

To remove the handle it the latter is moved from the position shown in Fig. 4 in the direction of the enlarged portion 2! of the keyhole slot to the position shown in Fig. 3 to clear the central portion 32 and free end portion 33. Due to the locking action of the leaf springs 28 a slightly greater force may have to be applied to, the handle l8 to initially disengage the heads 26 from the central portions 32. In this position of the handle the heads of the screw may be pulled through the enlarged portions 2| of the keyhole slot 59.

Figs. 5 and 6 show a modification of the invention and in this modification the leaf springs comprise a mounting portion 43, a central portion 44, a bridging portion 46,. a free end portion 4'! formed in the same general manner as that shown in the embodiment in Figs. 1-3 with the exception that the central portion 84 has a depressed portion 43 shaped to receive the head of a screw 9. With this construction when a handle 51 is in the position shown in Fig. 6 the heads of the screws are positively interlocked with the central portion 44 so that the parts cannot accidentally move relative to each other.

The above handle construction has many advantages. For example, the keyhole slots 19 may be formed in the panel 13 by a simple forming process and the leaf springs 22% may be formed by simple stamping processes. This construction has a minimum number of parts and consequently requires a minimum amount of time to efiect assembly or disassembly. Only one screw is required to secure each leaf spring in position and no manipulation of threaded parts is required to effect attachment and detachment .of a handle after the leaf springs have been assembled. The construction is positive in its action since a constant force is being applied to hold the handle in assembled relation.
