Abstract
Abstract A vehicle parking aid and signaling device having a housing section which encloses an electrical circuit connected with an electric switch for opening and closing the circuit and the circuit operatively connected with a signaling light or buzzer. The switch is actuated by having a movable lever arm maintained in direct engagement with an expandable elastic bulb which is operatively connected with a deformable tubular member filled with a fluid and which causes the elastic bulb to expand momentarily and effect closing of the electrical circuit containing the signaling light or buzzer when a wheel of a vehicle moves over and compresses the deformable tubular member; thereby indicating when the vehicle has reached a predetermined position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
A vehicle parking guide and signaling device comprising; a housing section adapted to be supported in a parking area, said housing section enclosing an electrical circuit and switch means for opening and closing said circuit operatively connected with a signaling means, said switch means having a movable lever arm associated therewith, a switch actuating resilient expandable means comprising an elastic bulb being maintained in direct engagement with said lever arm within said housing section, and said elastic bulb operatively connected with an elongated fluid filled deformable tubular member adapted to expand said elastic bulb when said deformable tubular member is deformed and move said lever arm so as to effect closing of said electrical circuit.
Claim 2
Dependent Claim
115 words
A vehicle parking guide and signaling device comprising; a housing section adapted to be supported in a parking area, said housing section enclosing an electrical circuit and switch means for opening and closing said circuit operatively connected with a signaling means, said switch means having a movable lever arm associated therewith, a switch actuating resilient expandable means comprising an elastic bulb being maintained in direct engagement with said lever arm within said housing section, and said elastic bulb operatively connected with an elongated fluid filled deformable tubular member adapted to expand said elastic bulb when said deformable tubular member is deformed and move said lever arm so as to effect closing of said electrical circuit.
Claim 3
Dependent Claim
72 words
A signaling device as in claim 1, wherein one end of said deformable tubular member with said elastic bulb mounted thereon is fixedly held within said housing section by a bracket and said one end of said deformable tubular member has an end cap section mounted thereon which encloses a portion of said elastic bulb so that said bulb is adapted to expand toward said lever arm when said bulb is expanded.
Claim 4
Dependent Claim
18 words
A signaling device as in claim 2, wherein said end cap section is formed integrally with said bracket.
Claim 5
Dependent Claim
59 words
A signaling device as in claims 2 or 3, wherein said end cap section has a tongue-like portion which extends toward said lever arm causing said elastic bulb to expand essentially toward said lever arm when pressure is applied to said deformable fluid filled means; whereby maximum pressure is applied to said lever arm when said bulb is expanded.
