The utility model can realize standing up smoothly without exerting great force on the legs, and is suitable for the elderly.
Description
Technical field
The utility model relates to a kind of furniture frame, relates in particular to a kind of the elderly's seat.
Background technology
The seat of existing common seat is level, and the people props health by leg power from chair immediately fully.Because the elderly's leg power deficiency causes dystasia.Because China has stepped into aging society, and the elderly is always in unheeded edge crowd, and therefore relevant the elderly's problem has become very important problem.Find by investigation, almost be not applicable to the seat special that the elderly uses on market; Therefore, need a seat that specially is suitable for the elderly's use of design badly.
The utility model content
The technical problem that the utility model solves is that the seat that provides a kind of the elderly of being suitable for to use, can realize without shank, very large strength just being stood smoothly.
In order to address the above problem, the utility model provides a kind of the elderly's seat, at least comprise combining seat, backrest, handrail and bearing together, described the elderly's seat also is provided with the seat height adjustment mechanism, described seat height adjustment mechanism is that two parallelogram four-bar linkages connect to form by cross bar, the inboard of described bearing side is fixed on described quadric chain base, and side is connected with described bearing side by returning spring; Described bearing side is provided with the first stopper slot, and described quadric chain side is provided with the first caging bolt, and described the first caging bolt can move in described the first stopper slot; Described seat is articulated in described quadric chain top margin, and described seat rear and front end is connected with described cross bar by spring, is used for limiting the angle of seat pitching.
Further, described backrest bottom is hinged with described bearing; Described bearing side is provided with the second stopper slot, and described backrest side is provided with the second caging bolt, and described the second caging bolt can move in described the second stopper slot.
Further, described handrail bottom is hinged with described bearing, and described bearing side is provided with the 3rd stopper slot, and described handrail side is provided with the 3rd caging bolt, and described the 3rd caging bolt can move in described the 3rd stopper slot.
Further, described returning spring is four, and left-right symmetry distributes; Described seat front springs is four, is extension spring, and spring left and right in rear end is respectively two, is extension spring.
Further, described the first stopper slot is four, and described the second stopper slot, the 3rd stopper slot are two, and left-right symmetry distributes.
The utility model has the advantages that:
By research the elderly's sitting posture custom, find out and cause the dysstatic basic reason of the elderly.Can realize without shank, very large strength just being stood smoothly.Utilize machine construction principle, but not use the electronic auxiliary force that is used as, simplify the structure of seat, weight reduction and production cost, reduce the power driven system fault rate, simple to operate, is applicable to the elderly and uses.

The specific embodiment
Hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that do not conflict, the embodiment in the application and the feature in embodiment be any combination mutually.
The utility model provides a kind of the elderly's seat as shown in accompanying drawing 1 to 2, at least comprise combining seat 1, backrest 2, handrail 3 and bearing 4 together, the elderly's seat also is provided with seat height adjustment mechanism 5, seat height adjustment mechanism 5 is that two parallelogram four-bar linkages connect to form by cross bar, the inboard of bearing 4 sides is fixed on the quadric chain base, and side is connected with bearing 4 sides by returning spring 61; Bearing 4 sides are provided with the first stopper slot 41, and the quadric chain side is provided with the first caging bolt 71, the first caging bolts 71 can be in the interior movement of the first stopper slot 41; Seat 1 is articulated in the quadric chain top margin, and seat 1 rear and front end is connected with cross bar by spring, is used for limiting the angle of seat 1 pitching.Backrest 2 bottoms and bearing 4 are hinged; Bearing 4 sides are provided with the second stopper slot 42, and backrest 2 sides are provided with the second caging bolt 72, the second caging bolts 72 can be in the interior movement of the second stopper slot 42.Handrail 3 bottoms and bearing 4 are hinged, and handrail 3 sides are provided with the 3rd stopper slot 43, and bearing 4 sides are provided with the 3rd caging bolt 73, the three caging bolts 73 can be in the interior movement of the 3rd stopper slot 43.Returning spring 61 is four, and left-right symmetry distributes; Seat 1 front springs 62 is four, is extension spring, and rear end spring 63 is four, is extension spring.The first stopper slot 41 is four, and the second stopper slot 42, the 3rd stopper slot 43 are two, and left-right symmetry distributes.
The state that do not stress, seat has certain inclination angle by extension spring, and the parallelogram sturcutre of fulcrum below is also in relaxation state, and the seat height is higher; As shown in Figure 3, due to center of gravity, at the fulcrum rear, when the people takes model in stress, seat can produce lever motion, produces certain angle, and connecting rod is compressing parallelogram four-bar linkage and starting distortion, and at this moment spring is tense situation; As shown in Figure 4, when the people will rise immediately, forward lean center of gravity reach, because the power that is applied to the extension spring that is positioned at rear reduces, the extension spring meeting produces reaction force, and parallelogram four-bar linkage also can be because extension spring restores to the original state, thereby be deformed into the form of conveniently standing up.Found through experiments, can be by lever motion and parallelogram principle, utilize people's position of centre of gravity in process that stands up to change to realize without shank, very large strength just to be stood smoothly.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
