Claim 8

The computer stand of claim 1, wherein said computer tray comprises: a seat member; and four side walls extending perpendicularly with respect to said seat member about the periphery thereof to form an opening for receiving a computer.

Claim 9

A computer stand for a vehicle, comprising: a support member having an outer surface and having first and second annular openings formed therethrough near each end, said annular openings each having an internal diameter, said support member having first and second slots formed therein extending from an outer surface thereof into communication with each of said annular openings, and each of said slots allowing the internal diameter of each of the annular openings to be reduced by compression of the support member adjacent the slots; a channel formed through the support member generally transverse to the axis of each of the annular openings and communicating with the slots; first and second pins received in said first and second annular openings, respectively, each pin having an external diameter slightly less than the internal diameter of the respective annular opening in the uncompressed state, allowing free rotation thereof; a base rigidly connected with respect to one of said first and second pins, said base adapted for attachment in the vehicle; a computer tray rigidly connected with respect to the other of said first and second pins, said computer tray adapted for supporting a computer thereon; a tension rod extending through said channel and mounted at one end to said support member adjacent one of said slots; and a cam mechanism connected to the opposite end of said support member adjacent the other of said slots for exerting tension on the tension rod relative to the support member to compress the support member, thereby reducing the internal diameter of said annular openings and frictionally engaging the first and second pins to lock them against rotations, wherein said cam mechanism comprises a handle operative to cause frictional engagement between said annular opening and said first and second pins by a single motion of the clamp handle to a clamping position.

Claim 10

A computer stand for a vehicle, comprising: a support member having an outer surface and having first and second annular openings formed therethrough near each end, said annular openings each having an internal diameter, said support member having first and second slots formed therein extending from an outer surface thereof into communication with each of said annular openings, and each of said slots allowing the internal diameter of each of the annular openings to be reduced by compression of the support member adjacent the slots; a channel formed through the support member generally transverse to the axis of each of the annular openings and communicating with the slots; first and second pins received in said first and second annular openings, respectively, each pin having an external diameter slightly less than the internal diameter of the respective annular opening in the uncompressed state, allowing free rotation thereof; a base rigidly connected with respect to one of said first and second pins, said base adapted for attachment in the vehicle; a computer tray rigidly connected with respect to the other of said first and second pins, said computer tray adapted for supporting a computer thereon; a tension rod extending through said channel and mounted at one end to said support member adjacent one of said slots; and a cam mechanism connected to the opposite end of said support member adjacent the other of said slots for exerting tension on the tension rod relative to the support member to compress the support member, thereby reducing the internal diameter of said annular openings and frictionally engaging the first and second pins to lock them against rotations, wherein said cam mechanism comprises a handle operative to cause frictional engagement between said annular opening and said first and second pins by a single motion of the clamp handle to a clamping position.

Claim 11

The computer stand of claim 8, wherein said cam mechanism is configured so that said clamp handle projects angularly away from said support member when said cam mechanism is released.

Claim 12

The computer stand of claim 8, wherein said computer tray comprises an upper surface having a plurality of Velcro pieces secured thereon.

Claim 13

The computer stand of claim 8, wherein said computer tray comprises: a seat member; and four side walls extending perpendicularly with respect to said seat member about the periphery thereof to form an opening for receiving a computer.

Claim 14

An article stand for a vehicle, comprising: a base adapted for mounting in the vehicle; a support member having first and second ends, and pivotally mounted at said first end to said base; an article tray pivotally mounted to said second end of said support member; a locking mechanism operatively connected with respect to said first and second ends of said support member to simultaneously releasably lock pivotal motion of said support member both with respect to said base and said tray; and wherein said locking mechanism comprises a handle operative to clamp both pivotal motions by a single motion of the clamp handle to a clamping position.

Claim 15

An article stand for a vehicle, comprising: a base adapted for mounting in the vehicle; a support member having first and second ends, and pivotally mounted at said first end to said base; an article tray pivotally mounted to said second end of said support member; a locking mechanism operatively connected with respect to said first and second ends of said support member to simultaneously releasably lock pivotal motion of said support member both with respect to said base and said tray; and wherein said locking mechanism comprises a handle operative to clamp both pivotal motions by a single motion of the clamp handle to a clamping position.

Claim 16
