When the device 10 is attached to the back or inside of
an inwardly opening door 11, as shown in FIGS. 6 and 7,
a plate 23 having upper and lower flanges is attached to
the door jamb 22 in a recess therein, and said plate 23
carries a knee member or hinge 24, 25, 26. One leaf 24
of said hinge is at one end pivotally secured to a vertical

pin 27 extending between said flanges, and the hinge is
spring-urged to swing away from the plate 23. A second
vertical pin 28 extends between said ñanges and is located
of the door when attached, and means for use in auto
