US4190379A — Device for reserving individual parking areas

Claim 1

Independent Claim 321 words

A barrier device for preventing unauthorized use of a parking area and for preventing unauthorized removal of a vehicle lawfully occupying the parking area, said barrier device comprising: a generally U-shaped rigid barrier element including a horizontal member having extending from opposite ends thereof two parallel leg members; a flat plate including means for rigidly fixing said plate to a floor adjacent an entrance to a parking area; said flat plate including bearing means for rotatively supporting said barrier element; said barrier element being fixed to said flat plate with said horizontal member rotatively supported by said bearing means for rotation in opposite directions about the axis of said horizontal member between an inoperative position, whereat said leg members extend substantially parallel to said flat plate and the floor of the parking space, and an operative position, whereat said leg members extend substantially vertically to said flat plate and the floor of the parking space; stop means on said barrier element for cooperative abutment with said flat plate for limiting the extent of rotation of said barrier element with respect to said flat plate in at least one of said opposite directions and for thereby defining said operative position; locking means cooperable with said stop means and with said flat plate for preventing rotation of said barrier element from said operative position to said inoperative position; said horizontal member having a length sufficient to allow a vehicle to pass over said barrier element when said barrier element is in said inoperative position; and said leg members having a length such that, when said barrier element is in said operative position, the upper ends of said leg members reach a height which is below the level of a bumper of a vehicle but which is sufficient to contact the undercarriage or lower parts of the vehicle, thereby presenting a barrier to the movement of the vehicle into or from the parking area.

Claim 2

Dependent Claim 321 words

A barrier device for preventing unauthorized use of a parking area and for preventing unauthorized removal of a vehicle lawfully occupying the parking area, said barrier device comprising: a generally U-shaped rigid barrier element including a horizontal member having extending from opposite ends thereof two parallel leg members; a flat plate including means for rigidly fixing said plate to a floor adjacent an entrance to a parking area; said flat plate including bearing means for rotatively supporting said barrier element; said barrier element being fixed to said flat plate with said horizontal member rotatively supported by said bearing means for rotation in opposite directions about the axis of said horizontal member between an inoperative position, whereat said leg members extend substantially parallel to said flat plate and the floor of the parking space, and an operative position, whereat said leg members extend substantially vertically to said flat plate and the floor of the parking space; stop means on said barrier element for cooperative abutment with said flat plate for limiting the extent of rotation of said barrier element with respect to said flat plate in at least one of said opposite directions and for thereby defining said operative position; locking means cooperable with said stop means and with said flat plate for preventing rotation of said barrier element from said operative position to said inoperative position; said horizontal member having a length sufficient to allow a vehicle to pass over said barrier element when said barrier element is in said inoperative position; and said leg members having a length such that, when said barrier element is in said operative position, the upper ends of said leg members reach a height which is below the level of a bumper of a vehicle but which is sufficient to contact the undercarriage or lower parts of the vehicle, thereby presenting a barrier to the movement of the vehicle into or from the parking area.

Claim 3

Dependent Claim 55 words

A device as claimed in claim 1, wherein said stop means comprises a bracket integral with and extending outwardly from said horizontal member at a position such that, upon rotation of said barrier element from said inoperative position, said bracket will abut with said flat plate when said barrier element is in said operative position.

Claim 4

Dependent Claim 63 words

A device as claimed in claim 2, further comprising an opening in said bracket, and a lug extending upwardly from said flat plate at a position to extend through said opening when said barrier element is in said operative position, said lug having a hole therein, and wherein said locking means comprises a member insertable into said hole to abut with said bracket.

Claim 5

Dependent Claim 88 words

A device as claimed in claim 1, wherein said stop means comprises means for alternate abutment with first and second separate stop surfaces of said flat plate for limiting the extent of rotation of said barrier element with respect to said flat plate in both said opposiet directions and for thereby defining both said operative position and said inoperative position, and wherein said locking means comprises means for preventing rotation of said barrier element when said barrier element is in both said operative position and said inoperative position.

Claim 6

Dependent Claim 120 words

A device as claimed in claim 4, wherein said flat plate has an integral raised portion having extending therethrough an elongated channel, said horizontal member extending through said channel, said raised portion having extending therethrough a radially and circumferentially extending groove, said groove having circumferentially spaced opposite end surfaces which comprise said first and second separate stop surfaces, and said stop means comprises a yoke integral with and extending outwardly from said horizontal member and through said groove at a position such that said yoke will abut said first stop surface when said barrier element is in said inoperative position and such that said yoke will abut said second stop surface when said barrier element is in said operative position.

Claim 7

Dependent Claim 20 words

A device as claimed in claim 5, wherein said first and second stop surfaces are circumferentially spaced by approximately 90°.

Claim 8

Dependent Claim 87 words

A device as claimed in claim 5, wherein said yoke has a hole therethrough, the radial depth of said groove adjacent said first and second stop surfaces is such that said hole in said yoke is exterior of said raised portion, the radial depth of said groove intermediate said first and second stop surfaces is such that said hole in said yoke is within said groove, and wherein said locking means comprises a member insertable into said hole to abut with exterior surfaces of said raised portion.

Claim 9

Dependent Claim 33 words

A device as claimed in claim 5, wherein said bearing means comprises bearing members inserted into said channel, said bearing members having upper convex surfaces complementary to the contour of said horizontal member.
