Stowable table system

Claim 2

A stowable table system adapted for use in a vehicle seat, or the like, for pivotal movement of a table body about three substantially mutually perpendicular axes between a stowed position and a position of use, comprising: a table structure including said table body; a hinge element attached to said table structure including a spherical body spaced from said table structure and a stem interconnecting said spherical body and said table structure; a hinge mount securing said hinge element for movement with respect to said seat including a body containing an elongated internal bore, a fixed surface at one end of said bore for bearing engagement with one side of said spherical body, a resiliently biased movable surface in facing relation to said fixed surface for bearing engagement with the other side of said spherical body, an elongated guide slot substantially coextensive with said bore extending through said body to the exterior thereof and being sized to receive said stem for translatory and rotational motion, and limit means at opposite ends of said guide slot against which said stem is rotatable, one of said limit means being disposed at one end of said guide slot to angularly displace said table structure in a vertical plane to and from said stowed position and the other of said limit means being disposed at the other end of said guide slot to angularly displace said table structure in a horizontal plane to and from said position of use.

Claim 3

The stowable table system as recited in claim 1 in which said table structure includes a table base, and means on said table base for attaching said table body for translatory guided lateral movement.

Claim 4

The stowable table system as recited in claim 2 in which said means for attaching said table body to said table base for guided translatory lateral movement comprises at least one bearing bar fixedly secured to one of the members of said table structure and means on the other of said members engaging said at least one bearing bar for locked, sliding movement therealong.

Claim 5

The stowable table system as recited in claim 2 in which said means for attaching said table body to said table base for guided translatory movement comprises at least one bearing bar fixedly secured to one of the members of said table structure and means on the other of said members engaging said at least one bearing bar for locked, sliding movement therealong.

Claim 6

The stowable table structure as recited in claim 1 including angularly spaced limit stop means engageable with said table structure for restricting the extent of displacement of said table structure in said horizontal plane.

Claim 7

The stowable table system as recited in claim 1 including means for adjusting the bearing pressure on said spherical body comprising a bearing pad containing said movable surface and an axially movable retainer housing threadedly received in said bore for adjusting the position of said bearing pad with respect to said spherical body.

Claim 8

The stowable table system as recited in claim 1 in which said hinge mount limit means includes a pin extending transversely of said guide slot and operative to engage said stem for rotational movement.

Claim 9

For use in a chair having a seat and an armrest containing a compartment adapted to receive a table body in stowed position, a stowable table system, comprising: a table structure structure including said table body; a hinge element attached to said table structure including a spherical body spaced from said table structure and a stem interconnecting said spherical body to the underside of said table structure; and a hinge mount securing said hinge element for movement producing pivotal movement of said table body about three mutually perpendicular axes between a stowed position within said compartment and a position of use exteriorly thereof, said hinge mount including a body fixedly secured to said armrest and containing a vertically elongated bore having a fixed surface at the upper end thereof and a resiliently biased surface movable in said bore in facing relation to said fixed surface for bearingly engaging and retaining said spherical body for compound pivotal movement therein, an elongated guide slot substantially coextensive with said bore extending through said body to the exterior thereof and being sized to receive said stem for translatory and rotational motion, and limit means at opposite ends of said guide slot against which said stem is rotatable, one of said limit means being disposed at one end of said guide slot to displace said table structure in a vertical plane to and from a stowed position in said compartment and other of said limit means being disposed at the other end of said guide slot to angularly displace said table structure in a horizontal plane exteriorly of said compartment to and from said position of use.

Claim 10

For use in a chair having a seat and an armrest containing a compartment adapted to receive a table body in stowed position, a stowable table system, comprising: a table structure structure including said table body; a hinge element attached to said table structure including a spherical body spaced from said table structure and a stem interconnecting said spherical body to the underside of said table structure; and a hinge mount securing said hinge element for movement producing pivotal movement of said table body about three mutually perpendicular axes between a stowed position within said compartment and a position of use exteriorly thereof, said hinge mount including a body fixedly secured to said armrest and containing a vertically elongated bore having a fixed surface at the upper end thereof and a resiliently biased surface movable in said bore in facing relation to said fixed surface for bearingly engaging and retaining said spherical body for compound pivotal movement therein, an elongated guide slot substantially coextensive with said bore extending through said body to the exterior thereof and being sized to receive said stem for translatory and rotational motion, and limit means at opposite ends of said guide slot against which said stem is rotatable, one of said limit means being disposed at one end of said guide slot to displace said table structure in a vertical plane to and from a stowed position in said compartment and other of said limit means being disposed at the other end of said guide slot to angularly displace said table structure in a horizontal plane exteriorly of said compartment to and from said position of use.

Claim 11

The stowable table system as recited in claim 8 including angularly spaced limit stops on said armrest and engageable with said table structure for restricting the extent of angular displacement of said table structure in said horizontal plane.

Claim 12

The stowable table system as recited in claim 8 including means for adjusting the bearing pressure on said spherical body comprising a bearing pad containing said movable surface and an axially movable retainer housing threadedly received in said bore for adjusting the position of said bearing pad with respect to said spherical body.

Claim 13

The stowable table system as recited in claim 8 in which said hinge mount limit means includes a substantially horizontally disposed stud pin extending transversely of said guide slot and operative to engage said stem for rotational movement about a horizontal axis whereby said table structure is angularly displaced in a vertical plane to and from said stowed position in said compartment.
