Patented Mar. 23, 1937 UNITED STATES QUQl bu uuun PATENT OFFICE DOOR STOP FOR AUTOMOBILE DOORS Harvey D. Geyer, Dayton, Ohio, assignor to General Motors Corporation, Detroit, Mich, a corporation of Delaware This invention relates to door stops, especially for automobile body doors.

An object of this invention is to provide a resilient door stop which is but slightly flexible in a vertical direction so as to permit only a possibly desired slight vertical movement of the closed door, but which has a substantial flexibility in a horizontal direction so as to yield materially when the door is pressed thereagainst in closing.

Another object is to provide such a resilient door stop which yields in a fore and aft direction without sliding of surfaces upon each other and hence without squeaking or wear.

Another object is to provide such a door stop having an insulating resilient non-metallic cushion between the metallic keeper recess and the door jamb, which properly sustains the closed door against excessive vertical movement but nevertheless yields in other directions by a distortion of the resilient cushion without sliding of adjacent surfaces upon each other, whereby to eliminate squeaking noises at the junction of the closed door and door jamb fixed to the body.

An important feature of the invention is the simplicity and economy of manufacture of the assembly of parts whichprovides the above objects.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred embodiment of the present invention is clearly shown.

In the drawing:

Fig. 1 is a face view of the dovetail keeper' which is fixed to the vertical door jamb. The metal cover plate is shown broken away on the left side of the figure to better show the interior structure.

40 Fig. 2 is a section on line 2--2 of Fig.1.

Fig. 3 is a horizontal section showing the tapered male wedge plate on the door about to enter the tapered female keeper on the door jamb. The section through the keeper is taken on line 3-3 of Fig. 2.

Fig. 4 is a section on line 4-4 of Fig. 2.

Fig. 5 is a face view of the tapered male wedge plate.

Figs. 6, 7 and 8 are views of the metal keeper recess member, Fig. 6 being a face view, Fig. '7 a side elevation, and Fig. 8 an end view from the direction of arrow 8 of Fig. 6.

Similar reference characters refer to similar parts throughout the several views.

The keeper assembly as shown comprises an open top and open front pressed metal housing I!) having two apertured attachment ears ll thereon, a pressed metal keeper recess member l2 resiliently retained within housing I0 by two portions l3 of soft rubber, and two pairs of hollow metal rollers l4 individually embedded in the rubber I 3 and located between member l2 and the .ends of housing I0 as best shown in Fig. 1. The metal parts l0, l2 and M are bonded by vulcanization in situ to the rubber portions I3 by properly locating these metal parts in the vulcanizing mold as inserts. Thus keeper member l2 and metal rollers l4 are very securely but resiliently retained in place within housing H! in a highly simple and eflicient manner.

Preferably rollers l4 are spaced slightly from both the end Wall is of housing In and the metal flange l5 of keeper I2, so that there will be small intervening layers I! of rubber l3, as best shown in Fig. 2. Metal rollers l4 are thus completely isolated by soft rubber from other metal parts and are thus permitted to roll or turn upon their axes by internal distortion of rubber l3. Their function is to substantially limit the endwise resilient movement of keeper member l2 within housing H) and yet at the same time to permit relatively free in and out resilient movement of rubber while the four metal rollers I4 have a sort of rolling motion within the rubber even though they are entirely surrounded by the soft rubber. However rollers I4 materially limit the relative movement of keeper l2 to the right or left in Fig. 1 since these rollers then function as non-compressible reinforcements in the otherwise resilient end cushions l3. This latter restricted movement is the vertical resilient movement of keeper l2 when assembled upon the door jamb 20, as shown in Fig. 3, and obviously may be made as small as desired by reducingthe thickness of the rubber layers IT. The above described relatively free in and out movement of keeper i2 is caused by the wedge plate 2| fixed to the door 22 entering the tapered recess I2 in keeper l2 when the door is forced to closed position, and will be hereinafter termed the closing move- -ment of keeper I 2.

In order to render this closing movement of keeper I! more free and easy, a clearance space 25 is provided between housing Ill and the parts l2, l3' and I4 which move relatively thereto (see Fig. 2). Obviously this clearance space 25 also prevents noise or rattling by preventing contact between housing I and keeper I2 and rollers It at all times. A clearance space 26 between the rear wall 9 of housing I0 and the movable parts l2, I3 and I4 is made sufficiently large that these movable parts will not contact this rear wall 9 during any closing movement of keeper I2. These clearance spaces 25 and 26 are provided by suitable cores when the parts l0,- l2, I3 and M are assembled by being vulcanized in situ in a mold as described above. This keeper assembly is fixed to the door jamb 20 by two large end screws 21 extending through the ears H. A metal cover plate 30 encloses housing l0 and is fixed thereabove by screws 21 and may have a small front flange 29 fixed to the door jamb by two small screws 28. This cover plate 30 is cut away, as at 3|, to permit the door wedge plate 2| to enter the tapered recess I2 of keeper l2 and to clear same at all times.

In operation, when door 22 is forced or banged closed the wedge plate 2| first enters and abuts the tapered recess 12 in keeper l2, and thereafter the shock of closing the door is absorbed by the resilient closing movement of keeper I2 as described in detail above. The door is held closed by the usual latch or lock against the tendency of keeper l2 to spring outwardly again. When in closed position the swinging edge of the door is resiliently sustained against up or down movement by the restricted vertical movement of keeper l2 as described above. All rattling or squeaking door noises ordinarily occurring in automobile doors are prevented by the elimination of all sliding or other contact between relatively moving parts in the keeper assembly.

While the embodiment of the present invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

1. A door stop for automobile doors comprising a keeper assembly fixed to the door jamb for receiving a projection fixed to the door, said keeper assembly comprising: a fixed base, and a metal keeper resiliently supported upon said base by resilient rubber and having a relatively restricted vertical movement which is opposed by a direct said base which is opposed by shear in said supporting rubber.

2. A door stop for automobile doors comprising a keeper assembly fixed to the door jamb for receiving a lateral projection fixed to the door, said keeper assembly comprising: a fixed housing, and a rigid keeper resiliently supported within said housing by soft rubber vulcanized in situ to both said keeper and housing in such manner that the door-closing movement of said keeper is resisted by shear in said supporting soft rubber, said rubber having clearance at the back thereof to prevent direct compression of said rubber by the door-closing movement.

3. A door stop for automobile doors comprising a keeper assembly fixed to the door jamb for receiving a projection fixed to the door, said keeper assembly comprising: a fixed housing, and a rigid keeper resiliently supported within said housing by soft rubber vulcanized in situ to both said keeper and housing, and an insert in said soft rubber which restricts vertical movement but permits relatively free door-closing movement of said keeper.

4. A door stop for automobile doors comprising a keeper assembly fixed to the door jamb for receiving a projection fixed to the door, said keeper assembly comprising: a fixed housing, and a rigid keeper located within'but isolated from said housing by resilient rubber, and an insert in said rubber which restricts vertical movement but permits relatively free door-closing movement of said keeper.

5. A door stop bumper assembly for automobile doors, comprising: a housing adapted to be fixed to the door jamb, and a keeper member resiliently supported by said housing by a connection of soft rubber, said keeper member having a relatively restricted vertical movement and a relatively free door-closing movement relative to said housing, said soft rubber being so arranged that it resists door-closing movement only by shear in the rubber but resists vertical movement of said keeper by a direct compression on the rubber.
