Appeal No. 96-3033
Application 08/139,574
Appellant’s invention pertains to a drop bolt system for
door security comprising a doorjamb restraint 24 mounted to a
doorjamb, and an elongate plate 22 rotatably mounted to the
doorjamb for receipt in a slot 36 in the doorjamb restraint to
block opening of a door. In a first embodiment, a latch 26 (see,
e.g., Figures 1 and 2) is mounted on the doorjamb restraint for
releasably engaging an upper edge of the elongate plate when the
plate is received in the slot 36 for preventing the plate from
being dislodged. Appealed claims 1-4, 7, 9, and 11 are directed
to the first embodiment. In a second embodiment, a pin 54 is
received in aligned holes in the elongate plate and the door when
the plate is received in the slot for preventing the plate from
being dislodged. Appealed claims 5, 6, 8 and 10 are directed to
the second embodiment.
Claim 1 is further illustrative of the appealed subject
matter and reads as follows:
1. A drop bolt system for door security comprising:
a. a doorjamb restraint mounted to a doorjamb and a
cripple underlying the doorjamb such that the restraint protrudes
