Abstract
Abstract An alarm device for mounting on vehicles comprising a switch and a plunger biased away from the switch, and an arm having the configuration of a backward S with the arm being pivotally mounted adjacent to the window of the vehicle, and the upper portion of the arm operatively engaged with the plunger and a lower portion being in abutting relationship with the window whereby the arm maintains the plunger in a depressed position when the window is closed and which is caused to pivot toward the window to release the plunger when the window is displaced from a closed position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
An alarm device for mounting adjacent the window of vehicles comprising a switch, a plunger biased away from the switch and an arm having the configuration of a backward S, said arm being pivotally mounted at an intermediate portion and having an upper surface in operative pressure engagement with the plunger and a lower surface adapted to abut a window of the vehicle when the window is in a closed position, said lower surface being curved downwardly and inwardly away from the window, whereby the arm maintains the plunger in a depressed position when the window is in a normally closed position and is caused to pivot toward the window to release the plunger when the window is displaced from the closed position.
Claim 2
Dependent Claim
123 words
