Abstract
Abstract A movement sensitive alarm includes a tamper-proof enclosure. A movement sensitive electrical contact switch, in the form of an elongate vertical conductive cylindrical housing and a freely movable pendular member suspended therein, is provided in the enclosure. The pendular switch forms a series connected element of an alarm circuit which is enabled by means of an on-off switch connected in series with the pendular switch. When used on a bicycle, the enclosure may be pivotally mounted on the axle of one of the bicycle wheels and movable from a position above the wheel when the bicycle is in use to a locked position below the wheel when the bicycle is parked. The enclosure is provided with a planar wall or surface which permits the enclosure to abut against a level portion of ground and adjustment means are provided for leveling the enclosure when not on level ground to position the freely movable pendular member in a non-contacting condition with respect to the conductive cylindrical housing. When the bicycle is tilted or abruptly moved, a closed electrical connection is provided by the pendular member contacting the conductive cylindrical housing to close the alarm circuit. When the bicycle is in use, the planar surface or wall of the enclosure which abuts against the ground when the bicycle is parked serves as a supporting surface above a wheel for supporting books or the like.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
159 words
An alarm in combination with a bicycle comprising a tamperproof enclosure, said enclosure being elongate and provided with two substantially opposing surfaces, one of said surfaces being circularly curved to follow the contour of an adjoining bicycle wheel and the other of said opposing surfaces being planar and suitable for abutting against a flat portion of the ground when the bicycle is parked and said enclosure is disposed below the wheel, pendulum means including a freely movable pendular member arranged within said enclosure for providing an open electrical connection when said enclosure is stationary and disposed in a predetermined position and for providing a closed electrical connection when said enclosure is disturbed or moved from said predetermined position; and circuit means connected to said pendulum means for generating an alarm signal when said pendulum means exhibits a closed electrical connection, whereby an alarm condition is established when said enclosure is moved in any manner to disturb said pendulum means.
Claim 2
Dependent Claim
159 words
An alarm in combination with a bicycle comprising a tamperproof enclosure, said enclosure being elongate and provided with two substantially opposing surfaces, one of said surfaces being circularly curved to follow the contour of an adjoining bicycle wheel and the other of said opposing surfaces being planar and suitable for abutting against a flat portion of the ground when the bicycle is parked and said enclosure is disposed below the wheel, pendulum means including a freely movable pendular member arranged within said enclosure for providing an open electrical connection when said enclosure is stationary and disposed in a predetermined position and for providing a closed electrical connection when said enclosure is disturbed or moved from said predetermined position; and circuit means connected to said pendulum means for generating an alarm signal when said pendulum means exhibits a closed electrical connection, whereby an alarm condition is established when said enclosure is moved in any manner to disturb said pendulum means.
Claim 3
Dependent Claim
50 words
An alarm as defined in claim 1, wherein said enclosure includes a hingedly connected wall forming a door to provide access to the interior of said enclosure; and locking means for locking said door to close said enclosure and for unlocking said door to provide access to said enclosure interior.
Claim 4
Dependent Claim
55 words
An alarm as defined in claim 1, wherein said enclosure is pivotally mounted about the axle of a wheel of the bicycle, whereby said planar surface is movable from a downwardly facing position below the wheel when the bicycle is parked to an upwardly facing position above the wheel when the bicycle is in use.
Claim 5
Dependent Claim
65 words
An alarm as defined in claim 3, further comprising clamp means adapted to pass through the spokes of the whEel and releasably engageable with said enclosure in locking relation thereto for locking said enclosure below the wheel when the bicycle is parked, whereby said enclosure is prevented from being moved to the position above the wheel for the purpose of unauthorized riding of the bicycle.
Claim 6
Dependent Claim
126 words
An alarm as defined in claim 1, wherein said pendulum means comprises an elongate conductive cylindrical housing being mounted in said enclosure to position the same in a substantially vertical position when said enclosure is in said predetermined position, said member being elongate and conductive and at least partially extending through said conductive housing; and insulating support means provided at one end of said conductive housing for pivotally supporting said pendular member, whereby connection of said circuit means to said conductive housing and to said pendular member provides an open electrical connection when said pendular means extends through said conductive housing without contacting the latter and provides a closed electrical connection when said enclosure is disturbed or moved and said pendular member contacts said conductive housing.
Claim 7
Dependent Claim
33 words
An alarm as defined in claim 5, further comprising bearing means on said insulating support means for supporting said pendular member with minimal friction during free pendular movements thereof within said conductive housing.
Claim 8
Dependent Claim
90 words
An alarm as defined in claim 5, wherein said pendular member comprises an elongate rod of substantially uniform cross section, said rod being provided with an enlargement at each end thereof, said insulating support means comprising an apertured disc fixed transversely at one end of said conductive housing, said rod extending through the aperture in said disc, and said enlargements being dimensioned to prevent the latter from passage through said aperture, whereby suspension of said rod by one of said enlargements from said disc permits pendular movements of said rod.
Claim 9
Dependent Claim
34 words
An alarm as defined in claim 1, further comprising adjustment means on said enclosure for leveling said pendulum means to provide an open electrical connection when the bicycle is parked on non-level ground portion.
Claim 10
Dependent Claim
40 words
An alarm as defined in claim 1, wherein said circuit means includes latching means for continuing generation of an alarm signal when an enclosed electrical connection is exhibited by said pendulum means; and reset means for deenergizing said circuit means.
Claim 11
Dependent Claim
32 words
A bicycle alarm as defined in claim 1, further comprising manual switch means provided in parallel connection to said pendulum means for initiating said alarm signal generation independently of said pendulum means.
