Description

The handrail structure-improved

The utility model relates to a kind of armrest.

The structure of general large-scale chair tool is shown in first figure, it mostly is the office chair that president, general manager or the person in charge take, its volume is big and heavy than general middle-size and small-size office chair, again because its volume is comparatively huge, so size of the handrail that the office chair both sides are fixing, must arrange in pairs or groups with chair, just conform with whole ratio, so the common volume of the handrail that large-scale office chair adopted is comparatively large-scale; Therefore the dealer is in order to save the employed material of handrail and to alleviate the weight of handrail, upper side edge or front side edge 1 except the support hand position in handrail top or the place ahead, 2, still must keep conforming with outside the bigger and wide ratio, be positioned at fixing back side edge 3, lower side 4 with office chair seat cushion and backrest place, then be designed to comparatively narrow solid shape, its maximum purpose is exactly for above-mentioned saving material and weight reduction; Simultaneously again in order to simplify the trouble in the manufacturing, handrail integral body all is one-body molded usually, promptly go up, preceding 1,2 side be the one ejection formation with back,

lower side

3,4, and the while after, bury packing ring underground in the set fixing hole of

lower side

3,4.

, above-mentioned armrest has following disappearance in practical application:

1, between the upper side edge 1 of handrail, front side edge 2 and back side edge 3, the lower side 4

Ratio, seem disproportionate and can't obtain suitable collocation, cause and look

Not serious loftyly do not take in the feel, and lose its sense of equilibrium.

Though 2 dwindle the width ratio of back side edge 3 and lower side 4, because its

Be solid shape, and fail to reach veritably the order of saving material and weight reduction

, therefore when we pick up this handrail, still can feel suitable heavy.

3, because handrail integral body is one-body molded, so can't be with each side by not homochromy

Transfer or the unlike material sense, arranging in pairs or groups gives expression to its characteristic, so the dull milli that seems

No change, shortage texture.

For solving the every disappearance on the employed handrail of above-mentioned known chair tool, main purpose of the present utility model is to provide a kind of handrail structure-improved that can save material and weight reduction;

Another purpose of the present utility model is to provide a kind of handrail that can arrange in pairs or groups mutually with different tones, unlike material.

A purpose more of the present utility model is to provide the collocation of a kind of overall appearance ratio to coordinate, and can obtain to conform with the handrail structure-improved of the visual balance sense of optimal proportion.

The utility model is achieved in that a kind of handrail structure-improved, be seat cushion and backrest both sides side at the chair tool, be fixed together with lower side that corresponds to handrail and back side edge, and on handrail lower side and back side edge, be provided with at least one fixing fixing hole of using and imbedding packing ring, it is characterized in that: lower side and back side edge are thinner body of rod shape, and its formed lateral surface is low slightly than the face of vicinity, other establish one with down, the back side edge shell shape decorations that are corresponding moulding cover, under these decorations cover and are fixed in by connector, on the back side edge.

As the further improvement of such scheme, it is characterized in that adoring covering and be provided with the cup-shaped flange of class that can stretch in the fixing hole corresponding to the fixing hole place, connector passed through behind flange and the fixing hole and was fixed on the chair tool.

As the further improvement of such scheme, it is characterized in that following, the formed lateral surface degree of depth of back side edge, just in time equate with the shell thickness that decorations cover.

The utlity model has following advantage:

1, the design of following, the back side edge thin rod shape of handrail makes handrail can reach real

Save the purpose of material and weight reduction;

2, handrail and decorations cover the design of separate type, can make both can with different tones,

The unlike material sense is arranged in pairs or groups mutually, more increases the characteristic of handrail;

3, again, decorations cover because of being the design of shell shape formula, so do not influencing handrail heavily

Under the situation of amount, the size design of its width dimensions can make whole with handrail

The collocation of external sight ratio obtains to conform with the visual balance sense of optimal proportion.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1: the organigram of existing handrail;

Fig. 2: the perspective exploded view of the utility model structure;

Fig. 3: the covering of the utility model decorations combines fixedly cutaway view with handrail;

Fig. 4: enforcement situation schematic diagram of the present utility model.

Shown in second figure, lower side 51 and back side edge 52 that the seat cushion of the utility model handrail 5 and chair tool and backrest are fixing, be to be ratio with handrail 5 upper side edges to differ bigger thin body of rod shape, and on lower side 51 and back side edge 52, be provided with a plurality of fixing holes 50, simultaneously in each fixing hole 50, bury a packing ring 53 underground, and make the face of lower side 51 and back side edge 52 formed lateral surfaces and vicinity lower; In addition, if one with down, back side edge 51, the 52 shell shape decorations that are correspondingly-shaped cover 6, and the shell thickness that makes this decorations covering 6 equals down, the degree of depth of the lateral surface of back side edge 51,52, be order decorations cover 6 be covered in down, after the back side edge 51,52, just in time can make decorations cover 6 appearance and be adjacent to down, smooth the trimming of face of back side edge 51,52.

Above-mentioned decorations cover 6 with time, combine fixed form between the back side edge 51,52, please cooperate shown in second and third and four figure, be to cover 6 corresponding to each fixing hole 50 place following, back side edge 51,52 at decorations, hyperplasia has the flange part 61 that can stretch into the cup-shaped in the fixing hole 50, and makes the bottom surface of this flange part 61 be provided with a perforation 62 than minor diameter; So when decorations cover 6 cover son down, during back side edge 51,52, each flange part 61 on it just in time stretches in each fixing hole 50, and the bottom outside face that makes flange part 61 is closely against on the packing ring of being buried underground in the fixing hole 50 53, after successively passing through flange part 61 and fixing hole 50 with a screw 8 by the outside then, and be fixed on the seat and backrest of chair tool, cover with a gag 7 in the lateral surface of consolidating flange part 61 more at last, even so handrail 5 and decorations covering 6 are fixed on the chair tool together, and have integral aesthetic property.

Because the design of the thin body of rod shape of following, the back side edge 51,52 of above-mentioned handrail 5 reaches outside the purpose of real saving material handrail 5, can reach the purpose of weight reduction simultaneously again; And the design with handrail 5 and decorations cover 6 employing separate types so can make both arrange in pairs or groups mutually with the design of different tones or unlike material sense, more increases the characteristic that highlights handrail 5 different textures; In addition, decorations cover 6 because of being the design of shell shape formula, thus under the situation that can the weight of handrail integral body do not exerted an influence, the size of its width can with the overall appearance ratio of handrail, work conforms with the good collocation of optimal proportion visual balance sense.

In sum, the fixing limit of the utility model handrail is the design with thin body of rod shape, and cooperates the decorations that separate to cover combination, is to make handrail reach material-saving, loss of weight, can keep the size sense of equilibrium of outward appearance the best again, improve the disappearance that existing handrail uses.
