DOOR HANDLE Herbert H. Heeman, Lakewood, Ohio Application August 10, 1937, Serial No.. 158,382
This invention relates to automobile door handles and more particularly to a door handle having a cushioning structure incorporated therein so as to prevent damage to the bodies of adjacent automobiles when the door is swung open.
Due to the current extensive use of the automobile and the conjested conditions existing in automobile parking lots where it is necessary to park the vehicles parallel to each other, damage is vbeing done to automobile bodies by the door handles which project beyond the door in a man-- ner so as to dent or gouge the body of adjacent vehicles when the doors are swung open. It is among the objects of my invention to provide a door handle in which that portion of the handle which may come into contact with an adjacent vehicle is cushioned by rubber or like resilient material so as to prevent any damage to the vehicle body-contacted. It is a further object of my invention to provide a door-handle in accordance with the preceding object which is attractive in appearance and in which the cushioning material is so embedded or secured to the body of the door handle as to become a part thereof. It is a 25 further object of my invention to provide a door handle for an automobileor the like in which a metal body is recessed or cut away on its outer face so as to receive and anchor a cushion or bufier device. It is a further object of my invention to provide a door handle for an automobile or the, like in which .a unitary rubber cushioning device is vul canized within re-entrant portions of the metal body of the handle. 'It is also among the objects of my invention to provide a door 35 handle in which a sheet metal handle cover portion is slotted or cut away to receive a cushion or V buffer adapted to project beyond the outlines of thedoody of the handle. Further objects and advantages will appear from the following description and the appended drawing wherein: Figure 1 is an'elevation of a door handle of the locking type embodying my invention;
Figure 2 is a longitudinal view, partly in section of the handle of Figure l; i 5
Figure 3 is an elevation of a modified form or; door. handle provided with a bufler device in accordance with my invention; V I Figure 4 is a longitudinal sectional. view'of the handle of Figure 3; v
Figure 5 is a sectional view taken along the line 5-5 of Figure 3; v Figure '6 isan elevation of a further modification of a door handle constructed in accordance 55 withmy invention;
- Figure '7 is a view partly in section taken at right angles to the showing of Figure 6. I
I have achieved the objects and advantages outlined ab'ove by cutting away a portion of a conventional door handle and vulcanizing or cementing within said cut away portion a rubber cushion material which is proportioned to project beyond the outlines of the door handle so that as the door is swung open that portion of the handle normally contacting an adjacent vehicle is cushioned by the projecting rubber.
In Figures 1 and 2 I have shown an embodiment of my invention wherein a door handle 5 of the locking type is die-cast or otherwise formed in a manner to provide a longitudinal groove 6 on the outer face thereof and an annular groove I joining the same adjacent the door shaft end of the handle. The handle may be provided with the conventional cylinder lock 8 'and may otherwise conform in shape to the design adopted by the designer of the particular motor vehicle. A longitudinal strip of rubber 9 is arranged within the groove 6 and that end of the strip 9 adjacent the lock portion is given an annular form as at In to fit within the groove 1. Preferably the body of the handle 5 is die cast with re-entrant portions as at I2 to receive anchoring portions i4 integrally. formed with the rubber strip 9. 'The integrally formed cushioncomprising'portions 9 and I0 may be vulcanized, cemented or otherwise suitably secured to the bodyof the handle.
My inventipn is. also adapted to that type of door handle shown in Figure 3 wherein portions of the handle 2| project both forwardly and rearwardly from the door shaft 22. In this form of my invention I prefer to cut-a plurality of annular grooves 23 into the body of the handle adjacent the door shaft and join the annular grooves 23 by longitudinal veins or bores 24. The handle may then be placed in a suitable rubber mold and the cushioning device integrally molded and interlocked about the handle. The large disc-like end portion 25 is secured to the smaller annular rings 26 through the medium of the longitudinal portions 21. In thistype of handle it will be understood that the cushionlng device is so interlocked by" molding the same about the body of the vehicle that further securing means such as cementing or further vulcanization is unnecessary.
-.My invention is also suited to that type. of door handle shown in Figures 6 and '7 wherein the bent end of a rolled rod is covered by a rough stamping 3! which in turn is encased by a chromium or nickel-plated stamping 32. In this type of hanmay come in contact with an adjacent vehicle when the door is swung open by slotting the outer sheet metal covering 32 as at 33 and inserting therein a buffer 34. The buffer 34 is preferably provided with a flange 35 .bearing against the inner surface of the sheet or cover'" and the buffer in its entirety is held in place by the rough stamping 3i. the outer cover 32 prior to the clinch or interlock of the metal as at 36 the buffer is immovably fixed to the handle and will function substantially as in the embodiments previously described.
In compounding the rubber which forms the buffers or cushions for the door handles according to my invention, I prefer to add mineral rubber in suflicient quantities to produce a relatively hard rubber. Those skilled in the art of rubber compounding will appreciate that the cushion or buffer may consist of such materials and be cured in a manner that will result in a product hard enough to resist cutting and yet soft enough to prevent damage to any vehicle body finish which it may contact. Synthetic rubber having the characteristics desired may also be employed. It will also be understood by those skilled in the art that the cushioning material may have incorporated therein or may be covered by such pigments or coloring matter as will match or harmonize with the general color scheme of the automobile.
Although I have shown and described three embodiments of my invention in considerable detail, it will be appreciated that modifications may be made therein by those skilled in the art without departing from the scope of the invention as defined in the following claims.
1. A door handle having a rubber cushion about one end thereof and a plurality of spaced annular rubber cushions secured to each other and molded within the body of the handle.
2. A door handle having a plurality of annular grooves formed therein and a plurality of longitudinal bores connecting said grooves, an integrally formed rubber cushion device molded within said grooves and bores having portions thereof projecting through said grooves beyond the outline of the handle to cushion the same.
3. An automobile door handle comprising a portion bent with respect to the door handle shaft, a sheet metal stamping encasing the bent portion, a slot formed through one face of said stamping and a buffer member secured between said casing and said bent end with a portion thereof projecting through said slot and beyond the outline-of the casing, said butler member constituting a permanent part of the handle.
