A table attaching construction for nursing chairs has longitudinally extending right- and left-hand table support frames, a table disposed on these table support frames, and right- and left-hand operating levers. The right- and left-hand operating levers are adapted to be turned between first locking and second release positions. When the operating levers are each in the first position, they are in engagement with the outer lateral portions and lower portions of the table support frames. When the operating levers are each in the second position, such engagement is canceled. The table attaching construction for nursing chairs further includes right- and left-hand slide members, and springs for urging these slide members to slide inwardly. Each slide member has an opening for the associated operating lever to extend vertically therethrough. Under the action of the springs, the wall surfaces of the openings in the slide members press the operating levers to maintain the latter in the first locking position. If an operating lever provided on one side of the table is turned to the second position and then, in this state, if the table is pushed to move toward the other side, then the engagement between the pair of operating levers and the pair of table support frames is canceled and the table can be removed by one hand only.

A table attaching construction for nursing chairs, comprising a table tray, longitudinally extending left- and right-hand table support frames (14, 15) on the left- and right-hand sides of a nursing chair, said table tray (17) being disposed on said left- and right-hand table support frames (14, 15)
A table attaching construction for nursing chairs, comprising a table tray, longitudinally extending left- and right-hand table support frames (14, 15) on the left- and right-hand sides of a nursing chair, said table tray (17) being disposed on said left- and right-hand table support frames (14, 15), left- and right-hand operating levers (18, 19), journal means (21) pivotally mounting said operating levers on the right- and left-hand sides of said table tray respectively, said operating levers being turnable between first locking positions and second release positions, said left- and right-hand operating levers (18, 19) being in engagement with the outer lateral portions and lower portions of the left- and right-hand table support frames when they are each in said first locking position, said engagement being cancelled when said left- and right-hand operating levers are each in the second release position, a left-hand slide member and a right-hand slide member (27) slidably arranged in said table (17), each slide member (27) having an opening (29) below said journal means (21), each operating lever (18, 19) passing through its respective opening in abutting engagement with its respective slide member for actuation of said left- and right-hand operating levers (18, 19) by the respective slide member, springs (30) arranged for urging said left-hand slide member and said right-hand slide member (27) into a locking position, whereby said abutting engagement of the wall surfaces of said openings (29) in said left- and right-hand slide members (27) with the respective operating lever normally maintains said left- and right-hand operating levers (18, 19) in said first locked position, and permits moving said operating levers into said second release position, said construction further comprising slide member operating means (31) for simultaneously sliding said left- and right-hand slide members outwardly into said release position, whereby the wall surfaces of the opening (29) in said left- and right-hand slide members turn said left- and right-hand operating levers (18, 19) into said second release position, and wherein said slide member operating means (31) comprise an operating button (32) slidably mounted in said table (17), and left- and right-hand pressing rods (35, 34) adapted to be displaced in response to a sliding movement of said operating button for pressing said left- and right-hand slide members outwardly, said journal means connecting said operating levers to said table tray in such a position that manually releasing one of said left-hand and right-hand operating levers (18, 19) individually permits sliding the other operating lever out of said locking position by a respective movement of said tray held in one hand, said operating button (32) individually releasing both operating levers simultaneously for the removal of said table with one hand only.
