VEHICLE DOOR LATCH HANDLE STRUC
TURE
Lake E. 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.

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.
