9' Claims.

This invention relates to latch devices and refers particularly to latches of the type designed for use on glove compartment doors of automobiles and the like.

More specifically this invention is directed to the so-called push button type of latch wherein depression of a push button actuator retracts the latch proper.

Inasmuch as these latches are mounted on the instrument board panel of the automobile, it is desirable to have their push buttons match the other units on the board and the internal trimmin-g of the car. 7

To this end it is an object of this invention to provide a latch device so designed and constructed that the push button actuator may be snapped into place as one of the final operations on the assembly line.

More specifically, it is an object of this in vention to provide a latch device of the type described wherein the push button actuator con sisting of a push button formed of plastic ice-- terial and a metal pusher part by which the thrust of the button is transmitted to the latch per se carries a spring retainer by having apart thereof confined between the metal pusher part and the plastic button, and so mounts this re tainer that the mere insertion of the actuator into the bore of the latch body secures the actu ator in place and utilizes the spring tension of the retainer to hold the'parts against rattling.

Another object of this invention resides in the provision of means for retaining the push one ton actuator assembled with the body of the latch in a way enabling disassembly thereof;

Another object of this invention resides in the provision of a latch device of the character -de* scribed wherein a single spring serves to retain the actuator in place in a manner permitting the same to be snapped into the bore of the latch body and also guides the actuator for longitudinal motion.

A further object of this invention resides the provision of a push button actuator for latches of the type described which consists of a plastic button and a metal pusher formed as a simple die casting and secured to a stern on the button by staking the metal of the pusher into the soft plastic body of the button stem.

With the above and other objects in View which will appear as the description proceeds, this invention resides in the novel construction, ombihation and arrangement Of parts substantially as hereinafter described and more particularly Port through the medium of the stood that such changes in the precise ehibodi merit or the heiihdislo's'd invention may be made as home within the scope of-the claims;-

The accompanying drawing illustrates one- 7 complete example of the physical embodiment of the invention constructed accordingto the best modeso' far devised for the practical application'- of the princi les thereof; and in which? s Figure 1 is a sectional vievv througih part'ofan automobile glove comps 'fn'ent illustrating the latch device of this invention in place thereon; Figure 2 is a perspective viewer the compo-"- nent parts of the actuator of the latchdevice shown disassembled; and r r i Figure 3 is a cross-sectional view take'n through Figure 1 on the plane of thelihe 3+3 1 Referring now particularly to the accom any--- ing drawing in which like numerals designate hire-parts, the numeral 5 designates the-door or an automobile glove oor'ripartfnent or any other enclosure', 0 r

Mounted on the door is the latch device or this invention, indicated generally by the numeral 6 and which consistsof a body l, an ac tuator 8} alatch 9, and a retainer HI.-

The body 1 is cores "for" the reception of th actuator and is preferably a die casting with a flange II at its front end encircling the mouth of its bore. This flange is covered by-a sheet metalshell- I 2 to insure a heat external appeararms as the flange is exposed at the front face ofthe door; -I

The retainer I0 isin the form of a cup fittedover the inner'end oftheibody and secured there: to by a clamping screw l3. Tightening the screw draws the retainer down against the back of the" door to clamp the door between it and the flange II. The latch 9' isp'ivotally mounted in'a'siot M in the top'wall ofthe body; A spring l5 con fined between the inner end of the latch and a spring seat for-lined iii the bodvyieldingly urges the latch to an operative position engag'eable behind a-keeper l6 upon closure of the compar'tmerit door. h g i Disengagenlent of the latch from its keeper is effected by rocking the latch on its pivo'tal' suppush button actuator 8. 7

Inasmuch as it is desirable to have the latch device or" at least its push button, which is forhied of a colored plastic, harmonize with the trimming or the automobile on which it is used, the attachment of the actuator is deferred until the automobile arrives at the final trimming defined by the appended claims, it being underp int on the assembly 1mg,

At this point an actuator having a push button of the proper color is snapped into place. To this end the actuator consists of a button I! of any suitable plastic substance such as casein, a metal pusher l8 and a spring retainer IS.

The button i! has an outer cylindrical portion of a size to fit slidably in the mouth of the bore in which the actuator is received and a rearwardly projecting stem H. The opposite sides of the stem are cut away or grooved as at 22 for the reception of two spaced arms or jaws 23 on the metal pusher l8. The pusher I8 is preferably a die casting and besides its two arms or jaws 23 has a cylindrical" midsection 24 and an inverted T-shaped inner end 25 so shaped to accommodate the internal formation of the body and actively to engage the The outer end portion of the spring ref tainer yieldingly, projects laterally from the actuator at a forward angle, that is, towards the button, so that upon insertion of the actuator into the body bore the free end of the spring retainer snaps behind a shoulder 31 and against the undersurface of a wall 32 which closes the slot l4 forwardly of the latch 9.

The shoulder 31 and the wall 32 arepart of a sheet metal stamping held in place by the finishing shell l2. For a more complete disclosure of this stamping reference is made to Patent No. 2,208,003, issued to Edward N. Jacobi July; 16, 1940.

The wall 32, it is to be observed, has an opening 33 adjacent to the back of the flange l;l so that the actuator may be disassembled from the body providing, of course, that the latch device is not in its mounted position illustrated in Figure 1.

Attention is directed to the fact that retainer not only enables the actuator to be snapped into place and thereafter holds the actuator against disassembly, but it also guides the actuator for longitudinal motion and cooperates with the spring l5 to hold the parts against rattling.

From the foregoing description taken inconnection with the accompanying drawing, it will be readily apparent that this invention provides an exceptionally expedient manner of attaching the push button actuators of glove compartment door latches, and that it assures having thebutton of the actuator match the trimming of the automobile in which the latch is installed.
