Abstract
Abstract A portable parking indicator is provided which signals the driver of a vehicle that he has reached a predetermined parking position in a garage or other regularly assigned parking space. The signaling means can be a light bulb, whose source of power can be either a battery or line voltage, which is actuated by the vehicle bumper depressing a contact plate mounted pivotably upright on a vertically adjustable lever and closing an electrical contact positioned between the contact plate and the lever. The lever is mounted pivotably upright on a movable base and is connected to tension means which holds the lever in an upright position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A portable parking indicator device which is placed in a vehicle parking space comprising: (1) a base which is placed at a desired position in the parking space, (2) a vertically adjustable lever mounted pivotably upright on the base, (3) a pressure contact plate mounted pivotably upright on the lever and adjusted in height to come in contact with the most forward point of the vehicle, (4) an electrical contact positioned between the contact plate and the lever, (5) first tension means between the lever and contact plate to hold the face of the contact plate in an upright position and to keep the electrical contact open except when the forward point of the vehicle moves the contact plate to close the electrical contact, (6) second tension means mounted to exert tension on the lever to hold it in an upright position, (7) signaling means connected to an electrical source, and (8) an electrical circuit connecting the contact points and the signaling means.
Claim 2
Dependent Claim
163 words
A portable parking indicator device which is placed in a vehicle parking space comprising: (1) a base which is placed at a desired position in the parking space, (2) a vertically adjustable lever mounted pivotably upright on the base, (3) a pressure contact plate mounted pivotably upright on the lever and adjusted in height to come in contact with the most forward point of the vehicle, (4) an electrical contact positioned between the contact plate and the lever, (5) first tension means between the lever and contact plate to hold the face of the contact plate in an upright position and to keep the electrical contact open except when the forward point of the vehicle moves the contact plate to close the electrical contact, (6) second tension means mounted to exert tension on the lever to hold it in an upright position, (7) signaling means connected to an electrical source, and (8) an electrical circuit connecting the contact points and the signaling means.
Claim 3
Dependent Claim
42 words
The device of claim 1 wherein the electrical contact is a pair of electrical contact points, one point of the electrical contact points affixed to the contact plate and the second point affixed to the lever in juxtaposition to the first point.
Claim 4
Dependent Claim
52 words
The device of claim 2 wherein the first tension means comprises an adjustable stop mounted on the lever and extending between the lever and contact plate and a pressure spring mounted on the pivot of the contact plate, said spring holding the contact plate in an upright position against the adjustable stop.
Claim 5
Dependent Claim
44 words
The device of claim 3 wherein the second tension means comprises a fixed lever stop mounted on the base and a tension spring mounted forward of the lever, said spring exerting a tension on the lever to hold the lever against the fixed stop.
Claim 6
Dependent Claim
36 words
The device of claim 3 wherein the second tension means comprises a fixed lever stop mounted on the base and a coil spring mounted on the lever pivot to hold the lever against the fixed stop.
Claim 7
Dependent Claim
21 words
The device of claim 3 wherein the signaling means is a low-voltage light connected to a battery as the electrical source.
Claim 8
Dependent Claim
70 words
The device of claim 1 wherein the electrical contact and first tension means comprise an adjustable stop mounted on the lever and extending between the lever and contact plate, a line voltage spring switch having contact points therein affixed to the lever in a position such that the switch contact points remain open and the switch exerts tension to hold the contact plate against the adjustable stop on the lever.
Claim 9
Dependent Claim
47 words
The device of claim 7 wherein the signaling means comprises a relay having a low-voltage relay switch, low-voltage terminals and power source terminals connected to line voltage, and a light electrically connected at moment of contact to line voltage terminals by action of the low-voltage relay switch.
