` PUSH BUTTON LATCH RELEASE DooR HANDLE Filed Jan. 21, 1952 INVENTUR. awa/d e/afffway @a ew United States Patent O PUSH BUTTON LATCH RELEASE DOOR HANDLE Gerald V. Jakeway, Grand Rapids, Mich., assignor to Keeler Brass Company, Grand Rapids, Mich., a corporation of Michigan Application January 21, 1952, Serial No. 267,477 10 Claims. (Cl. 292-3363) This invention relates to improvements in push button latch release door handles.

The main objects of this invention are:

First, `to provide a push button latch release door handle which is easy to operate, and one in which the push button is located and guarded so that it is very unlikely to become inoperative as the result of freezing or clogging.

Second, to provide a door handle of this type which may be readily embodied in attractive designs and for ready application to different door surface contours, such as automobile doors.

Further objects, and objects relating to the details and economies of the invention will appear from a description to follow. The invention is pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings in which Fig. l is a front elevational view with the handle mounted upon a door panel which is conventionally illustrated.

Fig. 2 is a bottom view of the handle.

Fig. 3 is an enlarged transverse section on a line corresponding to line 3 3 of Figs. l and 2, the handle being illustrated as mounted upon a door, and its operative relation to a catch release member being conventionally shown.

Fig. 4 is an enlarged fragmentary view on the line corresponding to line 4 4 of Fig. l.

Fig. 5 is a fragmentary view partially in section showing certain steps in assembling.

The embodiment of my invention illustrated in the accompanying drawings comprises a generally yoke-shaped body member 1 having an upwardly extending flange 2 on its inner edge. The front plate 3 is of generally curved section and is shaped to correspond to and complement the body member to provide a chamber 4 at least at one end of the handle. The front plate 3 is disposed with its outer edge 5 in edge abutting relation to the inner side of the body member and its inner edge 6 in lapping relation to the body member flange. These parts are formed as stampings. The nishing sheath 7 closely embraces the front plate and serves also as a connecting means for the body member and the front plate, it having inturned flanges 8 clampingly embracing the edges of the body member. The sheath may be chrome plated or otherwise suitably finished.

The body member has a slideway 9, for the push button 10 which is slotted at 11, to slideably receive the push button. In the embodiment illustrated the slideway is defined by the parallel slots i2. The tubular guide 13 for the plunger 14 is mounted in an opening 15 in the flange 2, as shown in Fig. 3, of the body member to project into the chamber 4. In the embodiment illustrated the guide is retained by means of annular upset portions 16 at each side of the flange 2. The plunger 14 is xedly secured as by welding, indicated at 141, to the inner side of the push button which is desirably cup-shaped as illustrated. The upper and lower ends of the slots 12 constitute stops for limiting the stroke of the push button, as is apparent by reference to Fig. 2.

For convenience in assembling the device the slideway 9 is transversely slit at 25 between the parallel slots l2 to permit deflection of the lower portion 26 as shown in Fig. 5. The push button is inserted through the resulting opening and welded to the plunger 14 after which the portion 26 is bent back into its normal horizontal position. The push button and plunger actuated thereby are retracted by means of thecoil spring 17 which is disposed to embrace the plunger, with its inner end in supported embracing engagement with the guide 13 and its outer end in thrust engagement with the inner side of the push button. The body member has a transverse offset 1S therein to accommodate the spring, this offset extending into the slideway.

ln Fig. 3 l conventionally show the plunger in operative relation to an actuated element 20 of a latch. 21 illustrates a door panel, and as many automobile door panels have curved surface portions, the embodiment of my invention illustrated is designed for mounting on a curved surface. To that end the body member is provided with threaded holes 22 adapted to receive attaching screws 23. The flange 2 is inclined to correspond generally to the inclination to the surface on which the handle is mounted so that when mounted the handle is in a horizontal position as is shown in Figs. l, 3, and 4. The yoke-shape of the handle provides a grip portion, the push button being at the end of this grip portion so that the push button may be manipulated with the thumb of a hand grasping the grip. The push button is disposed entirely on the under side of the handle so that it is guarded thereby and is not likely to become clogged by dirt or to freeze as water is not likely to reach it, but if water does reach the push button it drips away from the pushbutton and its slideway.

I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe other adaptations or embodiments which i contemplate, as l believe this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
