Description

Electrically propelled chair

The utility model relates to a kind of chair, refers in particular to a kind of electrically propelled chair that cooperates various sitting postures of regulating.

General chair tool is on structural design, mainly comprise cushion and chair back two parts, and support cushion and constitute its basic framework with foot rest, according to this when the user is sitting on the chair tool, be able to the chair back user back is formed suitable support, even for giving more comfortable sitting posture, more there is the chair tool that its chair back is done the design of adjustable angle of inclination, making it must look user's demand does vertical to the angular range adjustment that is tending towards level, can when adopting vertical or lie low sitting posture, the user all can form good supporting to the user back with the chair back.

Design with this type of chair tool, no matter whether its chair back possesses adjustable angle of inclination usefulness, right its sitting posture can't change basically, all be to adopt that buttocks is seated at chair cushion and both legs are stretched down naturally and trampled ground or be positioned over the form that pin leans on, only its back must be suitable angle by putting according to the chair back form that tilts, and obtains comfortable sitting posture according to this; Under this situation, basically be still the state of genus " underfooting on the head " because of its sitting posture, and be unfavorable for that qi and blood circulates, sit down for a long time, be easy to cause dizzy and the phenomenon that shank is numb of head anoxic, especially for the elderly, more often stand up to take place the of short duration dizzy problem that causes crank, falls down suddenly because of sitting.

The purpose of this utility model is to provide a kind of adjustable tilt angle, particularly can cooperate foot to be higher than the electrically propelled chair of the sitting posture of head.

For achieving the above object, solution of the present utility model is: a kind of electrically propelled chair, comprise chair frame and supported on both sides foot rest, wherein:

This chair frame is the support body of making according to the human body sitting posture curve, coats in its appearance and is provided with elastic pad, sets up a camber guide rod separately in the cushion both sides of chair frame, in camber guide rod two ends near its with chair frame bond sites inboard and be equipped with suitable gag lever post;

This both sides foot rest is provided with the chute of the arc-curved shape attitude of corresponding chair frame camber guide rod in its medial surface, extends tank respectively in the nearly end positions of its chute, is arranged with banking stop and the pivot group has pulley in tank;

Utilize the camber guide rod of chair frame both sides to agree with respectively in the default chute of embedding supported on both sides foot rest medial surface planning, and with chute two ends banking stop to guide rod form suitably cover the folder spacing, and pulley and guide rod are obtained contacted sliding compliance, use the assembly of finishing chair frame and supported on both sides foot rest, and give the chair frame and get mat both sides camber guide rod and cooperate with the foot rest chute and obtain to face upward the modulation usefulness of form of inclining;

Before the foot rest of both sides, link the cross bar position in addition and be provided with one group of motor expansion link, and the expansion link rank of motor is tied on the bridge of the nearly rear side in chair frame cushion position, use to such an extent that the chair frame is formed suitable angle support;

When the motor expansion link is in the projection state, be keep the normal morphology of chair frame, and control when contracting in the motor expansion link, but then drawing chair frame under the cooperation of its guide rod and foot rest chute, form the adjustment of different angles or be handstand state, to satisfy different sitting posture demands;

Wherein this both sides foot rest generally is herringbone and supports form, or other firm support forms, and its medial surface chute can be the curved attitude of continuous arc according to the foot rest form then, or the bent ordered state planning of arc at interval;

Wherein this motor expansion link is located at the foot rest rear transverse rod, and its expansion link rank is tied in chair frame cushion side lever frame nearby.When its chair frame was in the sitting posture form, the motor expansion link was to be in the recessed shape attitude, and when the outside projection of motor expansion link, faces upward the handstand state of hypsokinesis before then the chair frame will be thereupon according to this.

Owing to adopted such scheme, the assembly relation of inclining is faced upward in the activity that the utility model utilizes the camber guide rod to obtain via chair frame and foot rest, cooperation motor control expansion link is pulled to the top of chair frame or is contracted and draw, make the chair frame must in the scope of its camber saddle, exercise the adjustment of different angles, different sitting posture demands applicable to the user, and it is the change of whole sitting posture on adjusting, but not the part that known chair tool only can be done to adjust at chair back angle of inclination changes, thereby must be according to user's demand the sitting posture of realizing standing upside down, make its foot can be higher than head, to reach the effect of qi and blood circulation and reinforcement physical function.

The utility model will be further described below in conjunction with description of drawings and embodiment.
