Tiltable table structure

Claim 2

Claim 3

Table structure according to claim 1 including two pairs of brackets associated with the respective legs, each pair of brackets being joined to each other by the pivot means, one of the brackets of each pair being affixed to the tabletop and the other brackets of said pairs being affixed to the legs.

Claim 4

Table structure according to claim 2 in which each of the legs is formed by two ovular tubes of different major and minor axes so that one of the tubes is slidable and telescoped within the other for setting the height of the tabletop.

Claim 5

Table structure according to claim 3 in which ovular tubes are affixed to the bottoms of the legs to form floor rails.

Claim 6

Table structure according to claim 4 including gliding components which are plugged into the open ends of the ovular tubes forming the floor rails.

Claim 7

Table structure comprising two substantially parallel, vertical legs, single intergrated a tabletop, means for coupling the tabletop to said legs to render said tabletop tiltable, said coupling means comprising two pairs of channel members respectively associated with said legs, one of the channel members of each pair being immovably fixed to its respective leg, the other respective channel member being pivotally movable about the fixed channel member and having two cams thereon, the two movable channel Members being affixed to the tabletop, two pairs of spring-loaded latching devices respectively corresponding to said two legs, each latching device having a lever and an associated biasing spring holding said lever to one of the cams, two of the levers, one corresponding to each leg, being separately manipulated over their associated cams to move the tabletop to one position, the other two levers being separately manipulated over their respective cams to move the tabletop to a different position.

Claim 8

Table structure comprising two substantially parallel, vertical legs, single intergrated a tabletop, means for coupling the tabletop to said legs to render said tabletop tiltable, said coupling means comprising two pairs of channel members respectively associated with said legs, one of the channel members of each pair being immovably fixed to its respective leg, the other respective channel member being pivotally movable about the fixed channel member and having two cams thereon, the two movable channel Members being affixed to the tabletop, two pairs of spring-loaded latching devices respectively corresponding to said two legs, each latching device having a lever and an associated biasing spring holding said lever to one of the cams, two of the levers, one corresponding to each leg, being separately manipulated over their associated cams to move the tabletop to one position, the other two levers being separately manipulated over their respective cams to move the tabletop to a different position.

Claim 9

Table structure according to claim 6 in which each of the legs is formed of two elliptical tubes of different dimensions so that one is telescopically slidable within the other for adjustment of the height of said tabletop.

Claim 10

Table structure according to claim 7 including two linear floor gliders affixed to the bottoms of the legs, each floor glider being elliptical in shape and arranged so that the major axis is vertical and the minor axis is horizontal.

Claim 11

Table structure according to claim 8 including a stretch bar positioned between, and affixed to, both legs, the stretch bar being elliptical in cross-section.

Claim 12

Table structure according to claim 5 including a hollow tube extending between, and affixed to, both legs.

Claim 13

Tiltable table structure comprising a tabletop, a two-legged base for the tabletop, means for adjusting the angular position of the tabletop relative to the base over an angle substantially equal to 90 degrees, said adjusting means including: a. Two pairs of first and second plate members, the members of each pair being pivoted to each other, the first members being affixed to the tabletop, the second members being affixed to the respective legs of the base; b. two pairs of latching devices respectively associated with the two legs of the base and positioned between the respective plate members, each latching device having a lever and a cam held under continuous pressure against the lever by a spring, each cam having first and second contours, two selected levers one from each of the two pairs of latching devices being together manipulated to move the respective first contours of said cams over the corresponding levers to move the tabletop to a predetermined position relative to the base, the other of the levers from each of the two pairs of latching devices being selectively manipulated together to move the respective second contours of said cams over the corresponding levers to return the tabletop to its original position.

Claim 14

Tiltable table structure comprising a tabletop, a two-legged base for the tabletop, means for adjusting the angular position of the tabletop relative to the base over an angle substantially equal to 90 degrees, said adjusting means including: a. Two pairs of first and second plate members, the members of each pair being pivoted to each other, the first members being affixed to the tabletop, the second members being affixed to the respective legs of the base; b. two pairs of latching devices respectively associated with the two legs of the base and positioned between the respective plate members, each latching device having a lever and a cam held under continuous pressure against the lever by a spring, each cam having first and second contours, two selected levers one from each of the two pairs of latching devices being together manipulated to move the respective first contours of said cams over the corresponding levers to move the tabletop to a predetermined position relative to the base, the other of the levers from each of the two pairs of latching devices being selectively manipulated together to move the respective second contours of said cams over the corresponding levers to return the tabletop to its original position.

Claim 15

Tiltable table structure according to claim 11 in which each leg of the base comprises two linear tubes which are non-circular in cross-section and are telescopically slidable one within the other, and means for fixing the relative heights of both legs.

Claim 16

Tiltable table structure according to claim 12 in which the non-circular tubes are elliptical in cross-section.

Claim 17

Tiltable table structure according to claim 13 in which the two legs also include elliptical glider members interposed between the bottoms of the respective legs and the floor to reduce friction in the movement of the table structure along the floor.
