Foldable table having movable strut-retainer

Abstract

The foldable table includes a table top having a track, a rack and a strut-retainer on its underside. The strut-retainer is slidable along the track until a key with which the strut-retainer is provided engages any one of the teeth of the rack at which time, the strut-retainer is immobilized. A strut extends from the strut-retainer to a leg assembly which is pivotally attached to the table top. The angle of the table top can be adjusted by sliding the strut-retainer along the track.

1 . A foldable table comprising: a table top; a strut-retainer movable relative to said table top; means for selectively immobilizing said strut-retainer relative to said table top; a leg assembly pivotal with respect to said table top; and a strut extending from said strut-retainer to said leg assembly for immobilizing said leg assembly relative to said table top upon said immobilization of said strut-retainer. 
     
     
         2 . The foldable table of  claim 1  wherein said immobilizing means is located beneath said table top such that said strut-retainer can be activated and deactivated while said table is unfolded and while said table top is in position to support objects placed thereon. 
     
     
         3 . The foldable table of  claim 1  further including a rack stationary relative to said strut-retainer, said immobilizing means including a key associated with said strut-retainer for selectively engaging said rack for immobilizing said strut-retainer. 
     
     
         4 . The foldable table of  claim 3  wherein said key is located beneath said table top such that said strut-retainer can be activated and deactivated while said table is unfolded and while said table top is in position to support objects placed thereon. 
     
     
         5 . The foldable table of  claim 2  wherein said rack has a plurality of teeth and said key is slidable relative to said teeth, said key having a protrusion which, upon sliding of said key, slides from a first position in which said protrusion is in a space between adjacent said teeth with resulting immobilization of said strut-retainer in said track to a second position in which said protrusion is out of said space and allows movement of said strut-retainer along in said track. 
     
     
         6 . The foldable table of  claim 2  wherein said table top has an upper surface and an underside, said underside having a track along which said strut-retainer moves. 
     
     
         7 . The foldable table of  claim 1  further including a foot assembly having a horizontal portion for supporting said table in an upright position; and leg extending means for selectively increasing the effective length of said leg assembly such that the distance between said table top and said horizontal portion is adjustable. 
     
     
         8 . A foldable table comprising: a table top having an upper surface and an underside, a track associated with said underside; a rack; a strut-retainer, said strut-retainer being movable along said track and having a key which is selectively engageable with said rack and which, when so engaged, preventing said strut-retainer from moving along said track; a leg assembly pivotal with respect to said table top; and a strut extending from said strut-retainer to said leg assembly for preventing pivoting of said leg assembly relative to said table top. 
     
     
         9 . The foldable table of  claim 8  wherein said key is located beneath said table top such that said strut-retainer can be activated and deactivated while said table is unfolded and while said table top is in position to support objects placed thereon. 
     
     
         10 . The foldable table of  claim 8  wherein said rack has a plurality of teeth and said key is slidable relative to said teeth, said key having a protrusion which, upon sliding of said key, slides from a first position in which said protrusion is in a space between adjacent said teeth with resulting immobilization of said strut-retainer in said track to a second position in which said protrusion is out of said space and allows movement of said strut-retainer along in said track. 
     
     
         11 . The foldable table of  claim 10  further including a foot assembly having a horizontal portion for supporting said table in an upright position; and leg extending means for selectively increasing the effective length of said leg
