Description

The concealed board structural improvement of seat

Technical field

The utility model is the concealed board structural improvement about a kind of seat, is meant especially a kind ofly uprightly to stretch mode by track, and this mode can effectively be utilized collection space, and significantly increases the concealed board structural improvement of the seat of board usable floor area.

Background technology

As shown in Figures 1 and 2, for commonly using the seat perspective view of tool board, the seat of commonly using the tool board includes:

One seat 1, the hand steered seat 11 of these seat 1 one sides is a hollow body, and be provided with a hand steered lid 12 thereon, 11 of hand steered lid 12 and hand steered seats make its firm binding by a bonding pad 13, make hand steered lid 12 on hand steered seat 11, to overturn, and be provided with a groove 14 in the open front of hand steered seat 11 by bonding pad 13;

One board 2, a side of this board 2 is provided with a groove 21;

One pull handle 3, the front end of this pull handle 3 are provided with a pull handle hole 31, and rear end then level is penetrated with a hole 32, and on it and be provided with

several spacers

33,33 of this spacers keep a spacing;

One stator 4, a side of this stator 4 is provided with several breach 41, and in the side binding of breach 41 several hollow pipes 42 is arranged;

The hollow pipe 42 of stator 4 is placed the groove 21 of board 2, and make board 2 and stator 4 link mutually by locking part 43, simultaneously the hollow pipe 42 of stator 4 is inserted in spacer 33 spacings of pull handle 3, and make board 2 on pull handle 3, to overturn by the binding of latch 34, axle center hole 32 with pull handle 3 rear ends places in the groove 14 of hand steered seat 11 front ends again, and the binding by axle center latch 15, make pull handle 3 on hand steered seat 11, to overturn, and board 2 upsets are placed in the hand steered seat 11.

Shown in Fig. 3 A～C, for the enforcement action schematic diagram of the seat of commonly using the tool board, when the user manipulates, hand steered lid 12 is flipped open, and turn over turnback forward by the pull handle hole 31 of pull handle 3, board 2 is inwardly turned over turn 90 degrees again, to reach the purpose of use.

Though the seat of above-mentioned tool board can reach the effect of writing, but its board is to utilize the mode of axle center rotation to take out, the limited size that makes board is in radius of turn and hand steered seat size, make it can't reach best usable floor area, and when the user desires to take in board, not movable because of the pull handle hole, make in the process of placing board, to damage.

This shows that the above-mentioned article of commonly using still have many shortcomings, and demand urgently being improved.

The utility model applicant is urgently to think to be improved innovation in view of every shortcoming that the above-mentioned seat of commonly using the tool board exists, and after concentrating on studies through taking great pains to attain one's goal for many years, and successfully the concealed board structural improvement of this part seat is finished in research and development finally.
