5 claims.
This invention relates to rotary control handles
and particularly is directed to improved mecha
nism for raising and lowering the windows of
automobiles or other vehicles, the object, gen
5 erally stated, being to provide an improved handle
which, when not in use, may be recessed within
the door to eliminate interference with the ve
hicle occupants, which provides a symmetrical
design of the fitting to render the same more at
10 tractive, and which generally is more advan
tageous than the rigid crank-arm arrangements
conventionally employed.
The invention consists in the novel construc
tion, adaptation, and combination of parts here
15 inafter described and claimed, the preferred em
bodiment being illustrated in the accompanying
drawing, whereinz-f
Figure 1 is an elevational view representing the
invention as applied to anV automobile door.
Fig. 2 is an enlarged’plan view of the invention;
Fig. 3 is a transverse vertical section taken on
the line 3_3 of Fig. 2.
Particularly as respects the drawing, the refer
25 ence numeral 5 represents an automobile door
provided with a window 6 supported for vertical
movement by means of well-known or suitable
lever or gear mechanism which, as indicated, in
cludes a shaft ’I supported for rotary movement
30 and protruding from the inner side of the door.
According to the present invention, the ñxed
angle crank-arm conventionally utilized to im
part rotary movement to said shaft is replaced
by a member Il] of a relative disk shape formed
35 with a centralf socket arranged to iit over a
squared extension 8 of the shaft 1, a screw II
securing the same. Provided by said disk mem
ber is a radial cavity I2 the function of which
is to house a handle I3 to normally locate the
40 latter in a recessed position flush or nearly so as
respects the surface of the disk member, said
handle being pivotally mounted by means of a
pin I4 carried by the disk member at the outer
limits of the cavity. The handle, as represented
45 by full and dotted lines in Fig. 3, is adapted for
movement from normal recessed to an'exposed
position lying at right angles to the plane of
movement of the disk member, and for yieldably
maintaining the handle in either of said selected
50 positions, the hub I5 of the handle desirably is
`formed with planed surfaces I5’ disposed to en
(c1. 'i4-#547i `
‘ ‘
matically return the handle to recessed position
following use of the same. The cavity I2, as in
dicated, is somewhat of a pear-shape to form
ñnger recesses laterally of the handle in facilitat
ing the withdrawal of the handle to its crank 5
forming position.
To aiîord an open chamber within which the
disk member is rotatably received, I provide a
plate element I'I which preferably is designed to
fit an annular recess I8 formed in the inner wall 10
of the vehicle door, the plate element about its
perimeter having a trim-forming flange I9 which
operates to vcover the edges of velour or other
upholstery 9 employed in surfacing the door.
The invention should be clear in its provision 15
of a window-control arrangement which, when
not in use, lies ilush with the surface of the door
in a manner to prevent the same from interfering
with the driver or other occupant of the vehicle
either when entering and leaving the vehicle or 20
while riding in the same.
Modifications of the invention will readiy ap
pear and it is my intention that the invention
shall be limited only as by expressed restrictions
in the hereto annexed claims.
operatively engaging the spindle for rotating the
latter, revolubly received in the wall chamber
and formed in its exposed surface with a re
cessed cavity which lies in radial relation to the
disk to locate the same between the center and 35
the perimeter of the disk, and a crank handle for
operating the disk pivotally received in the disk
vrecess with its pivotal axis outermost for move
ment from an inoperative position within the
cavity to an exposed operating position approxi
mately at right angles thereto.
2. The structure defined in claim 1 wherein the
disk is of single-thickness sheet metal construc
tion peripherally provided with a reinforcing
3. A control crank for a rotary spindle com
prising the combination of a disk member having
a central socket arranged to operatively engage
the spindle and formed to provide a relatively
pear-shaped cavity in the exposed surface of the
. same disposed radially of the disk to locate the
gage a .fixed spring I6 secured to the ñoor ofA cavity between the center and the perimeter of
Any suitable spring, replacing the the disk, a handle-supporting shank pivotally re
fixed spring I 6, might as readily be used in modi ceived in said cavity for movement from a nor
the cavity.
fying the construction where it is desired to auto
What I claim, is:
1. In combination, a rotary spindle, a wall
structure through which said spindle extends
formed with an exposed cylindrical chamber ly
ing in concentric relation tothe spindle, a disk, 30
mal recessed position relatively ñush with the
disk surface to an upstanding position relatively
at right angles to the plane of movement of the
disk, and a handle-forming member sleeved over
the shank for relative rotary movement, the piv
oted hub of said shank lying in the restricted
throat of the cavity and toward the perimeter of
the disk whereby the sleeve lies in the greater
expanded portion of the cavity and toward the
disk center, said expanded portion of the cavity
10 being of a width to permit the introduction of
the fingers of the operator at each side of the
sleeved handle for withdrawing the handle from
the cavity.
4. In combination with a rotary spindle having
ment from a normal recessed position at which
the same lies flush with the disk member and
with the surface of the Wall to an exposed oper
ating position at which the arm extends in par
allel Arelation to the axis of the disk member from 5
the perimeter of the latter, the length of said
arm being less than the radius of the disk.
5. Crank mechanism for a rotary spindle com
prising a single-thickness sheet metal disk
stamped to provide a central socket by which 10
the same is fitted over the spindle and a recessed
cavity lying between the spindle-ñtting hub and
15 its end projecting from a wall structure into. a
the perimeter of the disk, and a cranking arm
normally disposed to lie in recessed relation to
the disk within the cavity and pivotally coupled 15
recess formed therein, crank mechanism for the
spindle comprising a disk member revolubly Vre
ceived in the wall recess to lie in flush relation
to the surface of the wall, and a cranking arm
20 pivotally carried by the disk member for move
to the disk for movement from its recessed po
sition into an exposed operating position at
which the arm extends in parallel relation to the
axis of the disk from the perimeter of the latter.
