Abstract
The utility model discloses an auxiliary chair, comprising a chair frame, a seat plate and a lifting mechanism with a power device, wherein the seat plate comprises a front seat plate and a rear seat plate; the seat plate is arranged on the upper end face of the chair frame; the front seat plate is rotatably connected with the rear seat plate; one end of the lifting mechanism is rotatably connected with the chair frame; the other end of the lifting mechanism is rotatably connected with the front part of the front seat plate; the lifting mechanism controls the front seat plate and the rear seat plate of the auxiliary chair to lift; the front seat plate is rotatably connected with the rear seat plate; the front seat plate of the auxiliary chair takes the front part of the front seat plate as a center shaft and rotates from back to front when the lifting mechanism ascends; and the front seat plate of the auxiliary chair takes the front part of the front seat plate as the center shaft and rotates from front to back when the lifting mechanism descends. The front seat plate is tightly attached to the thigh and provides a support to the body when a person gets up and sits down, so that the body is not in a suspended stage in the get-up process; the user does not need to use waist force; and the chair provides the support in the vertical direction so as to keep the body in balance.
Description
Technical field
The utility model relates to the assistive device field, particularly relates to a kind of auxiliary chair.
Background technology
Chair is requisite a kind of apparatus during people live, and particularly for the old,weak,sick and disabled, has the chair that a kind of minimizing exerts oneself and is necessary.
General chair comprises chair frame, seat board and backrest, in use, have on the seat board of difference in height with people's buttocks in order to sit on height, need rhaeboscelia, health backward, shift downwards can cause center of gravity to leave the axis of support of leg, for departing from of balance center of gravity, people's cognition bends forward, and buttocks and thigh can be suspended in the air can not be stressed, until buttocks touches seat support.A buttocks and thigh length time in unsettled stage are also arranged when in like manner, standing up from chair.This unsettled stage needs the waist leg to exert oneself to support and the balance health, to the elderly or other people because of disease waist skelasthenia, or can't do a little actions, or fall down or disequilibrium in this process easily, thereby need others assisting in.
At present, the part auxiliary chair is also arranged, use external impetus to make seat support integral body certain angle that turns forward, allow use obtain an auxiliary power that makes progress forward in the stage of initially standing up, but the angle that seat support tilts is limited, thereby otherwise allows easily user's buttocks to the wrestling of gliding.The restriction of angle center of gravity is raise and amplitude forward very little, very little to the degree of the auxiliary degree of standing up, still have a long-time buttocks and unsettled stage of thigh, health can not get supporting.
Summary of the invention
Based on this, be necessary for buttocks and thigh length time unsettledly, the problem that health can not get supporting provides a kind of auxiliary chair.
A kind of auxiliary chair, comprise chair frame, described auxiliary chair also comprises seat board and with the elevating mechanism of power set, described seat board comprises fore beam and back seat plate, and described seat board is arranged at the upper surface of described chair frame, described fore beam and described back seat plate are rotationally connected, and an end and the described chair frame of described elevating mechanism are rotationally connected, and the other end of elevating mechanism and the front portion of described fore beam are rotationally connected.The described lifting that can control auxiliary chair fore beam and back seat plate with the elevating mechanism of power set, because fore beam is anterior fixing with the chair frame rotation, and its rear end and back seat plate are rotationally connected, so, when elevating mechanism rises, the auxiliary chair fore beam is axle centered by the fore beam front portion, by backward front rotation.When standing up, described fore beam is close to thigh, for health provides support, does not have the unsettled stage of health when standing up, so the user need not to use waist power, and the support of vertical direction is provided by seat support, and it is stable to keep one's balance.When sitting down, elevating mechanism descends, and described fore beam is axle centered by the fore beam front portion, and by rotating behind the forward direction, described fore beam is close to thigh, for health provides support, do not have the unsettled stage of health, so the user need not to use waist power.
Among embodiment, the anglec of rotation of described fore beam is 0 ~ 90 degree therein.The angle of described fore beam and horizontal direction is 0 when spending, and is the normality of auxiliary chair, and namely the people is sitting in the state on the auxiliary chair; The angle of described fore beam and horizontal direction is 90 when spending, the state of the complete egress of chair of thigh of behaving, rotatable 90 degree of fore beam have guaranteed that the people stands up fully or is subject to the support of fore beam from the whole process thigh of the state of sitting up straight of standing up to fully from sitting up straight, and does not need to use waist power.
Therein among embodiment, described auxiliary chair includes connecting rod, be provided with chute on the described back seat plate back side or the described chair frame, an end of described connecting rod and the described back seat plate back side are rotationally connected, and the chute on the other end of described connecting rod and the described chair frame is slidingly connected; Perhaps an end of described connecting rod and described chair frame are rotationally connected, and the chute at the other end of described connecting rod and the described back seat plate back side is slidingly connected.Be provided with chute at the described back seat plate back side or chair frame, connecting rod can slide a distance in chute, when fore beam during horizontal by certain angle, back seat plate can have corresponding rotation along with fore beam, the two ends of connecting rod connect respectively back seat plate and chair frame, play the effect of supporting back seat plate, make back seat plate all keep at an arbitrary position level.
Therein among embodiment, described elevating mechanism comprises push rod, drive rod and power transmission shaft, one end and the described chair frame of described push rod are rotationally connected, the other end of described push rod and described drive rod are rotationally connected, the two ends of described power transmission shaft are individually fixed on the described chair frame, and described fore beam all is fixedly connected with power transmission shaft with described drive rod.Drive rod drives the power transmission shaft motion, thereby the angle of fore beam is changed; When power transmission shaft can guarantee to be attached thereto two-part relative position and changes in the expectation scope, transferring power reliably; Can guarantee that being attached thereto two parts evenly turns round, therefore, can guarantee that auxiliary chair is stressed evenly, can unstability.
Among embodiment, described chair frame comprises front foot rest and rear leg therein, and described front foot rest is at least two montants of described fore beam front portion, and the two ends of described power transmission shaft are connected with the top of described montant respectively.Described power transmission shaft is fixed on the montant of front foot rest, can make the transmission effect best.
Among embodiment, be provided with connector on the described fore beam therein, described connector is fixedly connected with power transmission shaft.On described connector, be provided with keyway with corresponding power transmission shaft, can make the rotation of power transmission shaft drive fore beam, and transmission be effective.
