Structure of mechanism |
| Function |
The invention relates to a folding ping-pong table including a support, two flat boards mounted on the support and mobile between a raised position and a lowered position, the support including a central structure and, for each flat boards, two legs positioned at each end of the flat board relatively to the central structure, as well aas locking means and remote actuation means for simultaneous control of the locking means of a same flat board. Said table is characterized in that, for each flat board, the locking means are positioned so as to allow direct blocking of the angular position between a leg and the corresponding brace, in the raised position and in the lowered position.
The squab has a backlash, which allows to pull the seatback down and to have a lower squab position in retracted position than in standard use position. The retractable position is like, such as the seatback most voluminous parts (lumbar supports) take place in the squab hollowest parts.
The seatback is linked up to the floor by a back and an intermediate connecting rod whose axis forme a first deformable quadrilateral. The front and the back connecting rods are inclined in the opposite direction, and their axis form a trapezium. That increases the stability and the wheelbase of the vehicle.
No elements exceed the back in relation to the standard use position. |
