Abstract
Abstract A storable table utilizes a sliding T-shaped block member disposed within an elongated T-shaped passageway located within an elongated supporting member. The supporting member is secured to a supporting structure so as to have its passageway disposed in a horizontal position. An L-shaped bracket has one leg secured to the block slideably engaged within the passageway. The other end of the L-shaped block is fitted with a plurality of pin receiving receptacles, disposed outwardly from a shaft secured in the lowermost regions, adjacent the pin receiving receptacles and radially therewithin. A table has a lock secured to an undersurface thereof, such block supporting at least one pin extending outwardly and disposed having its axis parallel to the axis of the rod. Spring means are provided for engaging the pin within the pin-receiving receptacle, such that the table is disposed in any plane desired.

Claim 1
Independent Claim
351 words
A storable table comprising a longitudinal track fastened horizontally to a supporting vertical structure, a longitudinal slot extending the entire length of the lowermost surface of a cavity in said track, said cavity extending the length of said track, a slideable support member within said cavity substantially shorter than the entire length of said track, and L-shaped bracket having a leg depending vertically downwards from the lowermost surface of said slideable support member, a shelf member, detenting means to removeably detentingly engage said shelf member to said L-shaped bracket in a selected one of a plurality of positions wherein a lateral surface of said shelf member is disposed in one of a plurality of planes, biasing means for urgingly and disengageably engaging a portion of said detenting means in any of said plurality of postions including detenting means whereby said lateral surface of said shelf is free to rotate in any plane when said biasing means are overcome wherein said detenting means comprises a plurality of pins, said pins being secured to said shelf in uniform spaced apart relationship about a bolt circle, a plurality of pin receiving holes, said pin receiving holes located in said leg and spaced apart uniformly about another bolt circle, said bolt circle and said another bolt circle having the same diameter, wherein said biasing means comprise a rod, a helical spring, said helical spring being disposed about a first portion of said rod, a second portion of said rod being disposed engaged with said leg, a block, said block being disposed secured to said shelf, a third portion of said rod being disposed secured to said block whereby said spring urges an adjacent surface of said block towards an adjacent surface of said leg, wherein said second portion of said rod is slideably and rotationally engaged with said leg, wherein said plurality of pins includes four pins, each of said pins being disposed defining the four corners of a square and wherein said four pins engage all of said pin receiving holes when said block is detentingly engaged with said adjacent surface of said leg.
Claim 2
Dependent Claim
351 words
A storable table comprising a longitudinal track fastened horizontally to a supporting vertical structure, a longitudinal slot extending the entire length of the lowermost surface of a cavity in said track, said cavity extending the length of said track, a slideable support member within said cavity substantially shorter than the entire length of said track, and L-shaped bracket having a leg depending vertically downwards from the lowermost surface of said slideable support member, a shelf member, detenting means to removeably detentingly engage said shelf member to said L-shaped bracket in a selected one of a plurality of positions wherein a lateral surface of said shelf member is disposed in one of a plurality of planes, biasing means for urgingly and disengageably engaging a portion of said detenting means in any of said plurality of postions including detenting means whereby said lateral surface of said shelf is free to rotate in any plane when said biasing means are overcome wherein said detenting means comprises a plurality of pins, said pins being secured to said shelf in uniform spaced apart relationship about a bolt circle, a plurality of pin receiving holes, said pin receiving holes located in said leg and spaced apart uniformly about another bolt circle, said bolt circle and said another bolt circle having the same diameter, wherein said biasing means comprise a rod, a helical spring, said helical spring being disposed about a first portion of said rod, a second portion of said rod being disposed engaged with said leg, a block, said block being disposed secured to said shelf, a third portion of said rod being disposed secured to said block whereby said spring urges an adjacent surface of said block towards an adjacent surface of said leg, wherein said second portion of said rod is slideably and rotationally engaged with said leg, wherein said plurality of pins includes four pins, each of said pins being disposed defining the four corners of a square and wherein said four pins engage all of said pin receiving holes when said block is detentingly engaged with said adjacent surface of said leg.
Claim 3
Dependent Claim
20 words
