28 Claims. (Cl. 292-—181)
This invention relates generally to door latches
for various types of door structures. The inven
tion is particularly, although not exclusively, use
ful in connection with latch devices adapted for
use in connection with the doors of automobiles
and other vehicles and contemplates the provision
of an improved door latch including a preferably
non-retractible latch bolt adapted to be installed

swinging bolt locking members are capable of
being simultaneously swung out of locking posi
tion by a kick-out or releasing member adapted
to be actuated to accomplish this purpose by
means of a push button control.

plurality of elevations and additional means con
trolled such as by a push button being provided
for shifting said devices.

Before explaining in detail the present inven
tion it is to be understood that the invention is
not limited in its application to the details of
construction and arrangement of parts illustrated
in the accompanying drawings, since the inven
tion is capable of other embodiments and of being
practiced or carried out in various ways. Also it is
i to be understood that the phraseolcgy or ter
minology employed herein is for the purpose of
description and not 'of limitation.
In the drawings there is illustrated, by way
of example, one embodiment of the present inven
