Abstract

The utility model relates to a frame of a chair, and particularly relates to a frame of a chair, which comprises a crossbeam, a foot stool and handrail frames, wherein the crossbeam is erected in the middle; the foot stool and the handrail frames are arranged at two sides; the chair foot stool mainly consists of a front stand bar and a rear stand bar; the top of each handrail frame is linear; each handrail frame is bent like an arc from the front end to the rear lower side; each handrail frame takes the shape of a hook wholly. When the hands hold the handrail, the palms naturally bend downwards. According to the frame of the chair, each handrail is crosswise bent from the front end to the rear lower side, so that the handrails are relatively in line with the human engineering; the design is free of corner angle edges, so that the safety and the reliability are provided; at the same time, the handrails are inclined toward the rear lower side, when sitting and rotating, people are not easy to touch the handrails to cause injures; each handrail frame is like a hook, so that the structure is simple, materials are saved and the appearance is elegant.

Description

A kind of chair frame

Technical field

The utility model relates to the framework of chair, in particular a kind of chair frame.

Background technology

Chair is the apparatus that people often use.The handrail pattern of existing chair is many, has plenty of and adopts a monoblock dividing plate as handrail, and this structural design is wasted material very much, and groups of people front sits up straight side again and turn, and shank is easily encountered handrail bottom, damages; The handrail that adopts in addition two orthogonal vertical bar plates to form, such handrail is saved material, but same meeting cause leg injury equally easy of monoblock iris type handrail; At present modal is the handrail of directly being made by a vertical bar plate, can save a large amount of materials, and side turns Shi Buhui and encounters handrail, but the front end of handrail has corner angle, even if handrail adopts arc design, still likely causes at any time people's bodily injury.The more employings of existing chair are directly directly installed on seating pad on chair pin in addition, and the main stress point of chair is the centre at chair, in the middle of chair, without any supporter, easily cause seating pad to damage.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple, elegant in appearance, and handrail design meets ergonomics, more safe and reliable chair frame.

For achieving the above object, technical solution of the present utility model is: a kind of chair frame, comprise the chair foot rest and the arm-rest frame that are erected at middle crossbeam and are arranged on both sides, described chair foot rest is mainly comprised of front support leg and rear leg, described arm-rest frame top linearly, by front end, to back lower place camber line, bent, whole arm-rest frame is hook solid.

Preferably, described crossbeam is hexagon steel pipe.

Preferably, described chair foot rest top is provided with the first securing member, and described arm-rest frame below is connected with the second securing member, and described the first securing member and the second securing member are to be removably fixed on crossbeam.

Preferably, the shape of described the first securing member and the second securing member is mated with crossbeam, and the first securing member and the second securing member are around embracing crossbeam.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: during hand steered firmly handrail, palm part can be bent downwardly by nature, handrail of the present utility model adopts and is bent to back lower place camber line by front end, more meet ergonomics, and without the design of corner angle limit, more safe and reliable; Simultaneously because it is the oblique back lower place, people sits up straight side while turning, and is difficult for encountering handrail and damages.Arm-rest frame integral body is hook solid, simple in structure, saving material, elegant in appearance.In the middle of the utility model, be provided with the crossbeam for support chair cushion, described crossbeam adopts hexagon steel pipe, and hexgonal structure is easily by force dispersion, and other structures of the impulse ratio can bear are large, increases the service life of cushion.

Accompanying drawing explanation

Fig. 1 is the utility model disassembled form structural representation;

Fig. 2 is that the utility model is specifically applied schematic diagram;

(in figure, identify: 1, crossbeam; 2, chair foot rest; 21, front support leg; 22, rear leg; 23, the first securing member; 3, arm-rest frame; 31, the second securing member; 4, bracing frame; 5, cushion; 6, backrest).

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

As shown in Figure 1, a kind of chair frame, comprise the chair foot rest 2 and the arm-rest frame 3 that are erected at middle crossbeam 1 and are arranged on both sides, described chair foot rest 2 is comprised of front support leg 21 and rear leg 22, described arm-rest frame 3 tops linearly, by front end, to back lower place camber line, bent, whole arm-rest frame 3 is hook solid, simple in structure, saving material, more elegant in appearance.Hand steered when handrail, palm portion all can habitually be bent downwardly, and steady of the present utility model crooked design for 3 hand gettings, in accordance with people's demand, meets ergonomics more; Handrail bending part adopts arc-shaped bend transition, is the design without corner angle limit, more safe and reliable; Because handrail front end is to back lower place camber line bending, there is certain distance handrail bottom from the front end of cushion, and people is sitting up straight side while turning, and can not bump bottom shank and handrail, damages.

As shown in Figure 1, 2, above chair foot rest 2, setting up crossbeam 1 can support chair cushion 5, and described crossbeam 1 adopts hexagon steel pipe, and hexgonal structure is easily by force dispersion, and other structures of the impulse ratio can bear are large, can increase the service life of cushion 6.For increasing support force, at crossbeam 1 mid portion, also fixedly mount two bracing frames 4, cushion 5 is by bolt lock above bracing frame 4, and backrest 6 also can be by bolt lock after bracing frame 4 in addition.

The utility model chair foot rest 2 is that the first securing member 23 by side disposed thereon is firmly fixed on crossbeam 1 around embracing.The first securing member 23 and crossbeam 11 form fit, can make it in conjunction with more firm, and preferred, the shape of the first securing member 23 is hexagonal.Wherein the first securing member 23 has been divided into two parts, and wherein a part is one-body molded with chair foot rest 2, and another part is to pin by bolt.Arm-rest frame 3 is that the second securing member 31 by arranging is thereunder fixed on crossbeam 1 around embracing, the second securing member 31 also with the form fit of crossbeam 1, therefore the shape of the second securing member 31 is also to adopt hexagon, two parts have been divided into equally, wherein a part is one-body molded with arm-rest frame 2, and another part is to be bolted.This design can reduce number of fitting parts, improves assembling speed, increases the firmness of chair; Because chair integral body is detachable, make to transport convenient.

Above-described, be only preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
