7 Claims.

' My invention relates to door handles, and particularly to door handle constructions for automotive vehicles, and it is the object of the invention to provide such a locking handle construction possessing new and novel structure and arrangement of parts,' whereby the handle is positioned close to or flush with the outside of the body of the vehicle or the like when inlocked position and extended from the body when in 10 unlocked position, the handle being operable also from the'inside of the vehicle.

'Another importantobject of my invention is to provide a door handle structure of the type described which is simpler in construction and operation than existing types of door handle structures, and which has fewer and less costly parts, and which may be made with fewer manufatuuring operations, the machining and other steps required being of elementary and simple character, and the assembly of the parts being easy and capable of being quickly performed.

Other objects and advantages of my invention will be apparent from a reading of the'following description in connection with the drawings,

a preferred embodiment of my invention.

In the drawings:

Figure l is a general vertical transverse sectional view through an automobile door or the like showing the construction and arrangement of the embodiment of the invention.

Figure 2 is a transverse sectional elevational view taken approximately on the line 2--2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 is a view of the inward end of the handle per se.

Figure 5 is a transverse vertical sectional view through Figure 4 taken approximately on the line Referring in detail to the drawings, wherein like numerals refer to like parts throughout the 5 same, the numeral 5 gen rally designates a portion of a modern automobile body or door construction the outer panel of which is represented by the numeral '6 and the inner panel thereof by the numeral 7. As the door handle construction is to be provided to be capable of being withdrawn except through the inner panel '7, this is provided with a large opening 9 provided with an outturned flange 10. Seated against the outward side of the panel 7 and provided with an i outwardly offset annular or flange 11, is a stamp ing or casting 12 which is riveted or otherwise suitably secured as at 13 to the outward side'of the panel '7 about the opening 9 in the manner shown. Attached to the inward side of the annulus or flange 11 is the flange 14' on a casting wherein for purposes of illustration I have shown between the inner panel 7 and the'outer panel of the door.

A retaining plate 17 adapted to seat its edges in a groove 18 in the inward face of the casting l5,- has a plug formation 19 adapted to project into the inward end of a rotatable member 20 to be. described. Detachable fastening means 21 traversing the retaining plate and entering the casting permit easily removing the retaining plate 1'7 when desired. It will be observed that radially inwardly of the groove 18 the same side of the casting 15 is provided with another groove 22 for rotatably receiving-a flange ,23 on the .inward end of the rotatable member to be described.

In the outside panel there is provided a relatively smaller opening 24 provided with an inturned flange 25 similar to the flange on the' panel 7. A solid or otherwise suitably constructed block 26 has a groove to receive the flange 24. A portion 27 of the block 26 is reduced "and extends to the groove so as to position the outer end of the block 26 flush with the outside surface of the panel 6. Suitable mounting means 28 for the block are passed through the panel 6.

As seen in the drawings, the block 26. is generally circular in cross section and has'a beveled inwardly directed portion 29, onthe small end of i which is formed a cylindrical portion 30 which is axially counterbored to provide a deep groove 31 for rotatably receiving the outward end of the rotatable member 20 to be described. The cylindrical portion 30 of the block 26 is provided also with a shallow counterbore communicating with the groove 31, the bottom of which is indicated in dotted lines at 32. Centrally-of the block 26 and communicating with the counterbore is an axial bore 33 for rotatably and slidably receiving the generally cylindrical shank portion of the handle which is generally designated 34.

From the lower side of the rotatable member 20 there depends and is affixed a lever or arm 35 to which is pivotally connected .a forked end 36 on a generally horizontal link 3'7 which has at its other end an enlarged portion 38 provided with a longitudinal slot 39,'in which slot operates a pin 40 on a crank arm 41 mounted on .a pivot 42 operable by,a suitable handle or l'ever arm 43 adapted to be disposed so as to 'be operable fr m. the inside of the door. This mechanism is adapted to operate the unlocking mechanism of the device of the invention from the'inside of the door independently of the operation or position of the door handle 34, and without disturbing the door handle 34 when it is in the locked position.

Reference to Figure 2 will disclose the provision ofa horizontally movable door locking bolt generally designated 44 which has one end movable through an opening in the appropriate edge panel 45 of the door .or body structure of the vehicle. The numeral 46 generally designates a suitable flexiblymounted bolt end for engaging the stationary detent on the door jamb for locking the door. On the other end of the bolt 44 on the lower side thereof is a series of teeth 47 which is meshed with the teeth of a segmental [gear 48 secured or formed upon the rotatable member 20, whereby rotation of the member is rendered effective to extend and withdraw the bolt 44 for locking and unlocking purposes.

Referring particularly to Figure 1, it will be seen that the rotatable member 20 comprises a generally cylindrical tubular body whose outward and the plain outward end of the rotatable member is a removable housing 49 containing a radially inwardly spring-pressed releasable detent 50 which radially projects into the interior of the rotatable member and into one of the longitudinal,

diametrically opposed grooves 51, 52 which are located in a portion therein having a reduced bore, which grooves are, as seen in Figure 2, disposed in a vertical plane. By virtue of its position in the groove 51, the spring urged detent .50 acts in connection with the inward end of the shank portion of the handle 34 to maintain it yieldably against idle longitudinal sliding movement inwardly while-it is in the'extended position. A generally horizontal helical spring 53 disposed so as to act between the plug por-' tion 19 of the retaining plate 1'7 and the inward end of the shank portion of the handle 34 is provided for projecting the handle outwardly when the lock means of the handle 34 are in the unlocked position. It will be observed that a portionof the interior of the rotatable member 20 having an enlargedbore as indicated at 54 extends to the inward end thereof. I

Theform and construction of the handle 34 will now be described. It comprises a generally cylindrical shank portion 34 on the inward end of which is a pair of diametrically opposed lugs or projections 57, 58 adapted to be positioned in the grooves 51, 52, respectively, whereby to connect the door handle 34 with the rotatable member 20 for rotating the member 20 by means of turning the handle 34 when the handle 34 is in an inward position. It will be obvious that when the handle 34 is pushed inwardly to a position in which the lugs or projections 5'7, 58 clear the inward end of the grooves 51, 52 and enter the portion 54, the handle 34 will be free to rotate in and relative to the member 20, and conversely,

the rotatable member 20 will then be freely rotatable with respect to the handle 34 by 'means of the inside operator 43'independently of the handle 34 when it is in the locked position. When the handle 34 is in the extended unlocked position, it rotates with the tubular member 20 when the same is rotated by the inside operator. It will, be observed that lugs or projections 59 of a stationary character are disposed at the outward end of the shank 56 and at its juncture with the transverse hand grip 60, whereby when the handle 34 is in the fully inward position with its lugs 57, 58 freely rotatable in the interior portion 54 of the member 20, the lugs 59 will be engaged in recesses 61 formed in the outward face of the block 26, whereby the handle 34 will be locked against rotation while seated approximately flush with the exterior of the door.-

.The handle 34'is equipped with a lock construction generally designated 62, seen in dotted lines in Figure l, which has an arrangement whereby to project spreader bolts 64, upon manipulating the keys 63 which, when the handle is in the inward position extend radially so as to engage behind the inward end of the block 26 and in an annular space defined by the outward end of the portion of reduced diameter in the member 20 and the bottom of the counterbore which is indicated in dotted lines at 32. Within this space thespreader'bolts are confined in a relatively rotatable manner, whereby the handle 34 is locked against outward withdrawal, and because of the interengagement of the lugs 59 and the, recesses 61, which obtains in this disposition of the handle the handle is also held against relative rotation. This will produce a condition in which the hand grip 60 will be positioned very close to the outside of the body or door of the vehicle, a highly desirable feature where the development of stream line forms for vehicular bodies is considered.

Though I have shown and described herein a preferred embodiment of the invention, it is to be definitely understood that I do not desire to limit the application thereof to the constructionand arrangement of parts herein, but any change or changes may be made, consistent with the spirit of the invention and the scope of the subjoined claims.
