Clinker, Toledo, Ohio Application December 5, 1936, Serial No. 114,408 3 Claims. This invention relates to door latches for vehi cles such as automobiles, but more particularly to door handle structures of the type in which the handle is adapted to be moved against the 5 side of the door in a position substantially flush with the outer surface of the door and an object is to produce a sturdy and reliable handle struc ture of thischaracter by which the handle in po~ sition of use is held against wabbling but which can begreadily and conveniently forced inwardly against the side of the door either by a person on the outside of the door or by a person inside of the vehicle extending his hand out through the window to engage the handle. 15 ' Another object is to provide a door handle structure of theabove character having the new and improved features of construction, arrange ment and operation hereinafter described and for purposes of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawing in which l Figure 1 is a perspective View of a door latch unit showing the new and improved handle as sembly connected thereto; Fig. 2 is an enlarged vertical sectional eleva tion ci a portion of an automobile door showing the handle structure mounted thereon; Fig. 3 is an enlarged fragmentary sectional ele vation of a portion of the handle structure show» 30 ing the handle parts in their outward position or in 'position of use; Fig. 4 is a composite perspective view of the to those skilled in this art and forms no part of the present invention. The roll back I6 is secured by a pin I1 to a squared o1“ non~circular shaft- |8 which extends through a similarly shaped opening in the head |9 of a tubular handle shaft 2U. In screw-thread ed engagement with the outer end of the handle shaft is a handle 2| which is held against un screwing by a screw 2 Ie. The handle 2| is adapt ed to be disposed in a socket 22 so that its outer surface is flush or substantially ilush with the outer side of a door D as shown in Fig. 2. It will be apparent that when the handle is not in use., it will lie snugly in its socket 22 so that the door can not be readily broken into and also» it is of 15 advantage when the automobile is in motion since it removes a projecting part which has, in the past, caused many serious injuries. In this in stance, the socket member 22 is a separate part, ñtting into an opening in the outside panel of '20 the door and is clamped in place by tongues 22a which engage the inside of such panel and a flange 22b on the outside thereof. ` Formed on the outer end of the roll back shaft I8 is a collar 23 and interposed between the co1 lar 23 and the handle 2| is a coil spring 24, which is compressed when the handle is in its inward or inoperative position and which urges the han dle outward to the position shown by the dotted lines in Fig. 2 and by full lines in Fig. 3, when 30 the handle shaft 2D is released. The handle shaft 20 telescopes with and has dog and its actuating member which is adapted bearing in a bearing sleeve 25 which is suitably to hold the handle shaft in its inward position, 35 and Fig. 5 is a sectional View on the line 5-5 of position andan enlargement '26 is'formed o-n the inner end oi’ the bearing sleeve 25. Formed Fig. 3, taken through the outer panel of the door showing the pocket or socket into which the han dle is forced. The illustrated embodiment of the invention 40 comprises a door latch having a case plate lil over which the bolt plate |I is suitably guided, the bolt plate having the usual latch nose I2 which extends through an opening in the case 45 plate flange I3. A spiral spring |4 has one end fixed to the case plate I0 and its opposite end bears against the bolt plate Il, urging the latter into latching position. Rising from the bolt plate is an arm I5 which is engageable by the usual 50 roll back I6 to enable the bolt to be retracted from the outside of the door as will be readily un derstood. Retraction of the bolt from the inside of the door is effected byremote control mecha secured to the door D to hold it in stationary in the enlargement is a socket 21 to receive a dog 28 which is slidable radially in the enlarge ment 26. Formed on the inner end of the han dle shaft 2D is an annular groove 29 into which the dog 28 is adapted to extend when the handle shaft is forced inwardly to its innermost position, thereby to hold the handle shaft in its .inward or inoperative position.> The inner end vof the en largement 26 is socketed to receive a hub 30 of the roll back It and the central portion of the roll back I6 on one side is socketed to receive the head I9 of the handle shaft 20. The head |9 is provided with an annular beveled surface 3| for a purpose which will hereinafter appear. The dog 28 is formed with a T slot 3| to receive a T-shaped actuating member 32 on the sternV4 of which is disposed a coil spring 33. The stem of nism (not shown), connected to the outer end of the actuating member 32 extends outwardly from 55 the bolt plate. The above structure is well-known the socket 2l through a cover plate 34 and into 2 2,117,943 engagement with an operating slide 35, a nut 3B engages the outer end of the stem of the actuator 32 for retaining the same in position. Spaced longitudinally from the enlargement 25 is an enlargement 31 of the bearing sleeve 25. The enlargement 31 is provided with diametrioal ly opposed sockets 3S to receive balls 39 which are spring pressed by coil springs 40, the outer -ends of which bear against screw caps 4|. Nor 10 mally or when the handle shaft 2!! is in its in ward position, the balls 49 engage in an annular groove 42 formed on the outer side of the shaft 2U. When the dog 28 is released or movedaway from the shaft 2li to allow the spring 24 to force the 15 handle shaft outwardly, the outward movement is limited by the collar 23 which is engaged by the head i8 and when in that position, the balls 3S engage in the annular groove 29 as shown in Fig. 3. When in that position, it will be observed 20 that the handle shaft 2S has a substantial bear ing in the bearing sleeve 25, thereby preventing wabbling of the handle when in use. The spring pressed balls 3S assist in holding the handle shaft in its outward position and provide an anti-fric 25 tion bearing for the shaft. When it is desired, the handle can be readily pushed in towards the door D without any dif ficulty, the beveled surface 3! engages the dog 33 and cams it out of the vway to allow the handle 30 shaft to be pushed inwardly to its fullest extent and to the point that the dog 23 engages in the groove 29. In this position, the handle 2| is dis posed within the socket member 22 substantially as shown in Fig. 2. 35 Release of the dog 28 can be readily effected from either side of the door. A finger 43 pro jects through a slot 44 in the inside of the door. The finger 43 forms a part of the slide 35 so that by lifting or pushing upwardly on the finger 43, 40 the dog 28 will be lifted away from the handle shaft 2&3. Actuation of the dog from the outside of the door is effected by means of the key 45 which engages a cylinder lock 46 from which eX tends a spindle ill. The inner end of the spindle 45 extends into an opening 48 formed in the slide 35 and projecting from the inner end of the spindle 4'! is a lug 4.9 which is adapted to engage one side or the other of the opening 48 to move the slide 35 in one direction or the other. In this man 50 ner, the slide 35 may be readily released by turn ing of the key 45 to lift the dog out of engage ment with the handle shaft 20. The arrange ment should be such that the key 45 can not be withdrawn from the lock 46 until the projection 55 ¿lâ is moved to such position that the dog 28 can be actuated by the spring 33 to operative position. Numerous changes in details of construction, arrangement and operation may be effected with out departing from the spirit of the invention, especially as defined in the appended claims. What I claim is: l. A handle structure for a vehicle door latch comprising a stationary bearing sleeve, an axially movable tubular handle shaft fitting said bearing 65 sleeve, a handle on the outer end of said shaft, manually releasable means carried by said bear ing sleeve for holding said handle shaft in its inward position, said releasable means compris ing a spring presseddog and an annular groove in said handle vshaft to receive said dog, a latch operating shaft fitting inside' of said handle shaft, said operating shaft being rotatable with said handle shaft and enabling longitudinal move ment of the handle shaft relative thereto, spring means urging the handle shaft outwardly of said bearing sleeve, spring pressed bearing elements carried bysaid lbearing sleeve and engageable in saidrannular groove for holding said shaft in 10 its outwardpositio'n and being automatically re leasable upon an inward push on the handle, and stop means for limiting the outward movement of said handle shaft at such point as to enable said handle shaft to have substantial bearing in said bearing sleeve, thereby to prevent wabbling of the handle' when in‘use.
