Abstract
The utility model discloses an adjustable armchair, comprising a seat, a backrest and supporting legs, wherein an armrest support frame is arranged on each of two sides of the seat respectively, and an armrest is movably connected to each armrest support frame and one end away from the backrest through a rotating member. When arms of a user are in various working states, the armrests can be rotated to a proper angle, then the armrests are vertically rotated to a proper angle according to the height of a working surface, and the evacuation end of each armrest is laid on the working surface. Because the upper surface of each armrest adopts an arc design in which two ends are gentle and the middle is raised, when the armrest is laid on the working surface, a smooth transition slope is produced at the junction, and thus the comfort degree is not affected. The adjustable armrest can be attached to human arms in the working state, so that the adjustable armchair meets the requirement of ergonomics, and supports the human arms to relieve fatigue brought by long-time working. The armrests can also be adjusted to the conventional positions in an idle state or as required.
Description
Technical field
The utility model belongs to daily life technical field, is specifically related to a kind of adjustable armrest chair.
Background technology
As being the convenient chair being equipped with of working in routine work and social activities, the kind of office chair is more and more.Comfortable as much as possible in order to accomplish, most of office chair has all done a lot of designs on backrest.Such as rotatable backrest meets backrest design of human body waist sizes curve etc.High-grade chair also increases massage functions on backrest, to eliminate work fatigue.Instantly office chair can solve human body back work fatigue problem to a great extent, but but seldom pays close attention to the most direct working portion---the comfort level of arm.The fatigue that arm work produces for a long time can cause the fatigue of whole health, and in the time considering the comfortableness of other parts of health, the comfort level of arm has been left in the basket.
Utility model content
The purpose of this utility model is to provide a kind of adjustable armrest chair, solved in prior art, exist fix the arm can not human nature supporting under each duty and produce the problem of arm fatigue because of armrests.
The technical scheme that the utility model adopts is: comprise seat support, backrest and supporting leg, the both sides of seat support are respectively arranged with handrail bracing frame, on handrail bracing frame and away from one end of backrest, are connected with handrail by revolving part.
Feature of the present utility model is also,
Revolving part comprises the turnbarrel of hollow, turnbarrel comprises the first sleeve, the first sleeve is vertically welded with the second sleeve communicating with it, in the second sleeve, be provided with rotating shaft, rotating shaft is connected with the second quill, the other end of rotating shaft offers groove and stretches out outside the second sleeve, and in groove, axle is connected with swingle.
First set jacket casing is on handrail bracing frame, and swingle is fixed on handrail.
The upper surface of handrail is the arc of the mild intermediate projections in two ends.
The beneficial effects of the utility model are, have solved the fatigable problem of arm work that the handrail that exists in prior art fixedly causes.By handrail that can Arbitrary Rotation, the arm that can fit all the time under various duties, effectively supports arm, alleviates work fatigue.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of structure of adjustable armrest chair, as depicted in figs. 1 and 2, comprise seat support 4, backrest 5 and supporting leg 6, the both sides of seat support 4 are respectively arranged with handrail bracing frame 3, on handrail bracing frame 3 and away from one end of backrest 5, are connected with handrail 1 by revolving part 2.
As shown in Figure 3, revolving part 2 comprises the turnbarrel 9 of hollow, turnbarrel 9 comprises the first sleeve 10, the first sleeve 10 is vertically welded with the second sleeve 11 communicating with it, in the second sleeve 11, be provided with rotating shaft 8, rotating shaft 8 is connected with the second sleeve 11 axles, and the other end of rotating shaft 8 offers groove 12 and stretches out outside the second sleeve 11, and the interior axle of groove 12 is connected with swingle 7.The first sleeve 10 is enclosed within on handrail bracing frame 3, and swingle 7 is fixed on handrail 1.The upper surface of handrail 1 is the arc of the mild intermediate projections in two ends.
Swingle 7 can be realized the rotation of the degree of 180 in vertical direction around rotating shaft 8.Rotating shaft 8 can be realized the rotation of the degree of 360 in horizontal direction around turnbarrel 9.Swingle 7 is fixed on handrail 1, and the cannulated sleeve of turnbarrel 9 bottoms is enclosed within on the handrail bracing frame 3 matching with its diameter by interference fit.
The operation principle of this device is that handrail 1 and handrail bracing frame 3 link by revolving part 2, revolving part 2 internal rotating bars 7 are that axle is connected with rotating shaft 8 slotting out, and therefore swingle 7 can be realized the rotation of the degree of 180 in vertical arrows direction as shown in Figure 3 around rotating shaft 8.Same between rotating shaft 8 and turnbarrel 9 is that axle connects, and therefore rotating shaft 8 can be realized the rotation of the degree of 360 in the horizontal direction of arrow as shown in Figure 3 around turnbarrel 9.Swingle 7 is fixed on handrail 1, and the cannulated sleeve of turnbarrel 9 bottoms is on handrail bracing frame 3 that its diameter matches by interference fit cover.By the work of said structure, handrail 1 can regulate in horizontal direction vertical direction, realizes our desired state.
Its using method is, as shown in Figure 1, and in the time that people's arm is various duty, handrail 1 can be horizontally rotated to suitable angle, then according to the height of working face, handrail 1 vertical rotary, to proper angle, is shelved on one end of handrail 1 emptying on working face.Because the side of handrail 1 is the camber line design of the mild intermediate projections in two ends, so can produce in junction the slope seamlessly transitting in the time that handrail is shelved on working face, therefore can not affect comfort level.The arm that the handrail 1 regulating can be fitted under people's duty, meets the requirement of human engineering more, supports people's arm, the fatigue that alleviating works long hours brings.As shown in Figure 2, off position or while needing handrail 1 also can recall to rotine positioning.
