In its broad aspect, the door catch of my invention com
prises a base provided With means for attachment to a
cabinet door frame or to other structural member. A
pair of ?exible arms extend outwardly ‘from the base in
the direction of the strike and terminate in opposed jaws
spaced to grip the strike releasably. Spring means then
are provided for applying resilient pressure primarily to
the jaw portions of the arms, thereby permitting lineal
adjustment of the catch as required to accommodate the
door strike when aligned, and also in various positions
of mis-alignment.
The door catch illustrated in FIGS. 1 and 2 is designed
tongue 62 and ?exible arms 64, 66 project outwardly
from the base. The arms are provided at their terminal
extremities with jaws 68, 70‘ formed with guiding surfaces
72, 74 respectively. These members preferably are
‘formed from an integral piece of plastic.
Spring pressure is brought to bear against jaws 68, 70
‘by means of a leaf spring 76 which may be pressed into
the plastic from the underside. It is to be noted particu
larly that this spring, like spring 45 of FIGS. 1 and 2,
?oats in its suspension so that pressure is exerted prin
cipally on the jaws without impairing the ?exibility of
arms 64, 66.
Accordingly it will be apparent that by the present in
vention I have provided a door catch which has manifold
for use with a strike member such as round headed screw 55 advantages. First, it includes but few parts and is easily

‘and inexpensively manufactured. Second, it compensates
able members, preferably on door 12, which the catch is
designed to anchor in position. The catch itself is mount
ed on the other such member, for example, on a cabinet
shelf or framing member 14.

The catch comprises a base 16 having an external re

located, inwardly extending tongue 20. Where the struc

Third, it can be installed easily and rapidly in a variety
of installation situations. Fourth, it is extremely durable
and has a long service life. Also, it is of attractive design
‘and appearance.
It is to be understood that the ‘form of my invention
