DOORLOCK MECHANI SM Filed Feb. 17, 1930 9% ATTORNEY Patented Oct. 18, 1932 UNITED STATES PATENT OFFICE ROBERT N. SMITH, OF KANSAS CITY, MISSOURI, ASSIGNOR TO JAMES L. HOGIN, OF
KANSAS CITY, KANSAS noonnoox MECHANISM Application filed February 17, 1930.- Serial No. 428,981.
My invention relates to improvements in door lock mechanisms. It is well adapted for use in connection with automobile door locks.
One of the objects of my invention is to provide a novel mechanism for forcing the closed door of an automobile toward the open position, when the door handle is operated to retract the bolt, thus enabling a person in the car to easily open a close fitting door.
A further object of my invention is to provide a novel mechanism of the kind described, which is simple, cheap, durable, strong, not likely to get out of order, which is readily applicable to door locks of usual type, and which is eificient in its operation.
The novel features of my invention are hereinafter fully described and claimed.
In the accompanying drawing, which illustrates the preferred embodiment of my invention, and modifications thereof,
Fig. 1 is an elevation of one form of my improved mechanism, showing it applied to a lock of usual type, a part of the door and a portion of the door jamb being shown in vertical section.
Fig. 2 is a section on the line 2-2 of Fig. 1, the lock being shown in plan.
Fig. 3 is a section on the line 33 of Fig. 1.
Fig. 4 is a reduced elevation of a modification of the pull line supporting means, and a portion of a lock to which it is applied.
Fig. 5 is a reduced elevation of a modified arrangement of the pull line and parts connected therewith.
Similar reference characters similar parts in the different views.
1 designates a lock casing of usual type mounted on a car door 2, and having the usual bolt 3 retractible by an oscillative handle 4 from a recess 5 in a door jamb 6, and also retractible by means of an outer handle 7 the handle 4 being at the inner side of the door. By means, not shown the bolt may designate be withdrawn from the recess 5 by either handle independently of the other.
For pushing the door toward the open position, when the handle 4 is swung tothe right, as viewed in Fig. 1, to retract the bolt 3, there is fitted on the horizontal shaft of the handle 7 a collar 8 on which is oscillatively mounted a push member 9 having a finger 10, which is movable through a slot pro videdt-herefor in the casing 1 into engagement with a downwardly inclined strike surface 11 of a strike plate 12 mounted in a recess 13 which extends to the outer side of the ja-mb 6, Figs. 1, 2 and 3.
For swinging the push member 9 into such engagement with the strike plate 12, the push member has an arm 14 to which is connected flexible means, such as a wire or cable 15, as shown in Figs. 1, 2 and 4, or such as a chain 15, as shown in Fig. 5. Said flexible member 15 comprises a pull line which is attached to the handle 4. In the form shown in Figs. 1 and 2, the pull line 15 has running engagement with two pulleys 16 and 17 disposed at the right of the push member 9 and at theleft of the handle 4, as shown in Fig. 1.
WVhen the handle 4 is swung from the initial position shown in'solid lines in Fig. 1, to the position shown in dotted lines in said figure, it will first retract the bolt 3, and will, by means of the pull line 15, swing the push member from the position shown in solid lines in Fig. 1 to the position shown in dotted lines, in which last named position, the finger 10 will have had sliding engagement with the inclined surface 11, thus pushing the door 2 toward the open position.
I A close fittingdoor, thus partly opened, may be easily opened fromthe inside of the car. V
WVhen the handle 4 is swung back to the initial 'positionto permit. the bolt 3 to enter the recess 5, the push member 9 will be retracted to its initial position, shown in solid lines in Fig. 1 by a coil spring 18 one end of which is attached to the push member 9 above the fulcrum of the latter, and the other end of which is fastened to a pin 19 mounted in the casingl, Figs. 1 and 2.
In case the handle 4 is utilized, as in many instances, for locking the car door by being swung to the left of its initial position, shown in solid lines in Fig. 1, the flexible pull line 15 will slacken to permit such movement of the handle a without effecting any movement of or pressure on the push member 9. V
In the form shown in Fig. 4, in which the handle 4 swings to the left of the initial position, instead of to the right, as in Fig. 1-, to retract the bolt 3 from the recess 5 in the jamb, the pulleys 16 and 17 are disposed at the right of the handle 4, as is shown in Fig. 4. In other respects the construction and mode of operation is the same in the form shown in Fig. 4,, as in the form shown in Fig. 1.
In the modification, shown in Fig. 5, the
pull line 15', which may comprise a chain, as
shown, or which may be a flexible wire or cable, as in Fig. l, is extended directly from the arm 14 of the push member 9to the handle 4 to which it is attached. In this form the pulleys 16 and 17 are eliminated. The mode of operation is the same in the form shown in Fig. 5 as in the form shown in Fig. 1, with the exception of the elimination of the running connection with pulleys. 7
There is sufficient lost motion ofthe parts to enable the handle 4 to withdraw the bolt 3 from the recess 5, before the push 'inember engages the inclined surface 11 of the strike plate 12. I
I do not limit my invention to the structures shown and described, as other modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.
WVhat I claim is p 1. In a door lock, the combination Witha lock casing, abolt therein and a handle movable on said casing in opposite directions from an inactive initial position, of a door opening push member movable on said casing to and from a position in which'it is adapted to push against a jamb for opening the door, and a flexible pull line connecting said handle and said'push member which forces the latter to said pushing position when said handle is moved in one of said directions from said initial position, and which yields and does not operate said push member when said handleis moved in the other of said directions from said initial position.
2. In a door lock, the combinationwith lock casing, a bolt therein'and twohandles on said casing, one of sa1d handles being movable in opposite directions from an inactive initial-position, of a door opening push'member oscillative on the other of said handles and movable thereon to and from a position its
