A kind of chair of shock-absorbing
Technical field
The present invention relates to field of furniture, specifically refer to a kind of chair of shock-absorbing.
Background technology
Earthquake has brought uncertain disaster to the mankind's life, and we have temporarily gone back look-ahead not this disaster, so we will prevent in advance.In the time of a lot of, precipitate earthquake has been given us huge loss and injury, during coming earthquake, also has a lot of people to be caught unprepared, and psychology puts upon the full stretch, and does some too drastic things, and psychological stress just easily loses one's marbles, and the judgement thing just easily produces mistake.
Summary of the invention
To between sitting board of chair and bracing frame, hinge be set, seat can be lain down, the baffle plate of arc is set below seat, when seat is lain down, baffle plate will be along slideway to the top that is positioned at seat.
Technical scheme of the present invention
A kind of chair of shock-absorbing, it comprises: baffle plate (1), left chain wheel (2), left chute (3), right pulley (4), right rail (5), right hinge (6), left hinge (7), neckpillow (8), tie-bar (9), pedal (10), broadcast box (11), lamp (12), recording pen box (13).
Under the chair seat, bracing frame upper end in both sides arranges right hinge (6), left hinge (7), after baffle plate (1) camber is placed in backrest, baffle plate (1) the right and left connects respectively left chain wheel (2), right pulley (4), and backrest lower end and seat bracing frame lower end arrange respectively left chute (3), right rail (5).
Beneficial effect of the present invention
1, simple to operate during earthquake, effect is remarkable;
2, simple in structure, be difficult for having other type problem to cause normally using;
3, with low cost;
4, reduce the threat of earthquake to life.
The accompanying drawing explanation
Fig. 1 is the bright schematic diagram of this law;
Fig. 2 is schematic diagram of the present invention.
The specific embodiment
Under the chair seat, bracing frame upper end in both sides arranges right hinge (6), left hinge (7), after baffle plate (1) camber is placed in backrest and under seat, baffle plate (1) the right and left connects respectively left chain wheel (2), right pulley (4), and backrest lower end and seat bracing frame lower end arrange respectively left chute (3), right rail (5).Neckpillow (8) is connected in the backrest top, and tie-bar (9) is arranged on the symmetrical position of baffle plate (1) arc, and pedal (10) arranges the top of baffle plate (1), and broadcast box (11) and lamp (12) and recording pen box (13) are arranged on the below of baffle plate.
Below illustrate the effect of each parts.
Baffle plate (1), be applicable to harder thing, as steel plate, just can better prevent that some heavier things from dropping on baffle plate; Left chain wheel (2), move quickly into the top of chair easily; Left chute (3), make baffle plate (1) within certain working region; Right pulley (4), facilitate the top that moves quickly into chair of baffle plate (1); Right rail (5), make baffle plate (1) within certain working region; Right hinge (6), descend seat, and when running into earthquake, the muscle power of recumbency consumption is less than and is seated or the muscle power of couchant consumption; Left hinge (7), coordinate right hinge (6) that seat is descended, and when running into earthquake, recumbency consumes one's strength to be less than and is seated or couchant consuming one's strength; Neckpillow (8), make head have a fulcrum more comfortable when seat decline user overlies; Tie-bar (9), for the handle of supporting baffle (1) and this function of use; Pedal (10), when baffle plate is positioned at top, pedal, in pin head position, can be opened pedal, makes shank more comfortable; Broadcast box (11), can place broadcast, conveniently hears government or rescuer's message during earthquake; Lamp (12), throw light on, and can use battery and 5 volts of LED electricity-saving lamps of 2500 milliamperes, a joint; Recording pen box (13), place recording pen.
Below a kind of operation principle of chair of shock-absorbing:
When arising suddenly coming earthquake, race has little time, we just need to take some stringent effort, the user can sit on seat, two have pulled on tie-bar (9) and have moved, left chain wheel (2) and right pulley (4) are fixing respectively is obedient to left chute (3), right rail (5) makes to move on baffle plate (1), on seat is obedient to baffle plate (1) when moving radian moving down slowly, right hinge (6), left hinge (7) is along with the closure that moves down speed, move down into low side after seat to the bracing frame top under chair, head is supported by neckpillow (8), pedal (10) is with kicking the automatically vertical with ground level of lower inertia.
