Door guard with alarm device

摘要

A combination door lock and alarm consists of an adjustable shaft, two pads which are able to pivot, and an automatic alarm. The pads are provided with non-skid surfaces which ensure the stability of the device. The pivot feature of the pads allows quick set-up of the device without the need of extensive adjustment. A novel alarm actuating means is also disclosed, which consists of a spring clip in contact with a toggle switch. The use of the toggle switch allows for a continuous alarm signal, even after pressure is removed from the device. The alarm actuating means is activated by a spring loaded shaft, which will be pushed into the main shaft of the device as pressure is applied to the door. The spring clip is mounted on the outside of the spring loaded shaft and the movement of this shaft is what forces the clip to trip the toggle switch. The unit is designed to fit conveniently into a suitcase for travel and can be suspended from a door knob when not in use.
