A foldable table includes a seat secured to a chair, a shaft pivotally secured to the seat at a pivot axle and rotatable from a horizontal position to a vertical position, and a board pivotally secured to the shaft at a pivot pin and rotatable relative to the shaft to a horizontal working position. A casing is secured to the board and includes a hub for rotatably receiving the shaft. A plate is secured to the casing and has a curved slot for receiving a fastener extended from the shaft and for limiting the rotational movement of the shaft relative to the board and the casing.
A chair comprising a base structure (12) bearing a seat (14), a backrest (16) and a writing tablet (38) movable between a first lowered inoperative position and a raised operative position, in which in the first lowered inoperative position the tablet (38) is parallel to a vertical axis and is inclined relative to a vertical plane parallel to the longitudinal axis of the chair, so that two or more chairs of the same type can be approached longitudinally to each other with the tablets of two adjacent chairs partially superposed on each other. The writing tablet (38) is also provided with a second lowered inoperative position in which the tablet is inclined relative to a vertical axis and is inclined relative to said vertical plane parallel to the longitudinal axis of the chair, so that two or more chairs of the same type can also be superposed vertically on each other with the tablets of two adjacent chairs partially superposed on each other.
The invention relates to an armchair tablet hinge system. According to the invention, the tablet (1) is mounted to an armrest of the armchair by means of a support (4), said support containing a hollow shaft (5). The end of the hollow shaft is provided with a head (6) to which the tablet (1) is articulated by means of a cam-shaped element (7). In addition, rod (10) is housed in the aforementioned shaft (5) and is pushed against the cam-shaped element (7) by means of a spring (11). Moreover, the end of the rod (10) can be inserted into a notch (13) in the cam (7) in order provisionally to block the rotation of the tablet (1).
An apparatus for the ergonomic positioning of a computer pointing device comprising a generally planar support member, an armrest attachment member, an adjustable coupling for attaching the support member to the armrest attachment member, and a plurality of straps for mounting the armrest attachment member onto the armrest of a chair. The adjustable coupling provides for rotational positioning of the support member around an axis parallel to the user's line of sight to the monitor, tilt positioning of the support member around an axis perpendicular to the user's axial line of sight to the monitor, and lateral positioning of the support member relative to the armrest attachment member. The armrest attachment member has a generally U-shaped cross-section adapted to fit over the existing armrest of a chair, and the attachment straps, which have Velcro.TM. fasteners or the like, fasten the armrest attachment member securely onto the armrest.
A chair and tablet combination has a tablet movable from a generally horizontal, operative position above the seat and in front of the backrest to a vertical stored position beside the chair. The chair may have upright and reclined positions for the occupant, and the tablet remains stationary when the chair moves from one position to another.
A chair comprising a base structure (22) bearing a seat (32), backrest (36), and a writing table (42) which can be moved between a lowered, inoperative, position, and a raised, operative, position. In the aforesaid lowered, inoperative, position, the table (42) is inclined with respect to a vertical plane (A) parallel to the longitudinal plane of symmetry of the chair, in such a way that two or more chairs of the same type can be set longitudinally against one another, with the tables of two adjacent chairs partially overlapping one another.
