Pool guard alarm apparatus
First Claim
1. A pool guard alarm apparatus, comprising:
- an alarm body, having a case to accommodate a circuit board and a battery for providing power source, the circuit board comprising several buttons and a sound member, the buttons protruding outward from the case for enabling an operator to key in a pass code and to bypass an alarm mode;
a relative triggering element, located on either of a gate and a doorframe at the entrance of an area around a pool; and
a triggering device, located on either of the gate and the doorframe, corresponding to the relative triggering element, the triggering device comprising a movable part which is elastic and retractable to change an engaging state with respect to the relative triggering element upon opening or closing of the gate, thereby producing a triggering signal to the circuit board, the circuit board when in the alarm mode activating the sound member to produce an alarm sound after a predetermined time,wherein the movable part of the triggering device is a movable conductive post driven by a conductive elastic member, a fixed conductive plate being provided on the sliding way of the movable conductive post, the fixed conductive plate and the movable conductive post being electrically connected to the circuit board respectively, the movable conductive post disengaging with the fixed conductive plate when the movable conductive post is against the relative triggering element, the movable conductive post urged by the conductive elastic member being in contact with the fixed conductive plate to produce a triggering signal when the movable conductive post is not against the relative triggering element.

Abstract
A pool guard alarm apparatus includes an alarm body, a triggering device and a relative triggering element. The alarm body accommodates a circuit board and a battery for providing a power source. The circuit board is provided with several buttons and a sound member. The buttons enable an authorized person to bypass the alarm mode. The triggering device located at the entrance to the pool has a movable part which is elastic to be against the relative triggering element. The moveable part will produce a triggering signal to the circuit board when the entrance is opened. The circuit board activates the sound member to produce an alarm sound after a predetermined time. The alarm sound is repeated after a period of time while in the alarm mode. When the entrance is then closed, the user must reset a pass code to activate the said alarm mode.
