Abstract
The utility model discloses a kind of seat support edge strip (1), offer the groove of strip, it is characterized in that, the cross section of described edge strip (1) is the rectangle of a side (2) indent, female parts forms limited mouth (3) at described side (2), is formed between accommodating area (4) at described rectangle inside.
Description
Technical field
The utility model relates to chair art, is specially a kind of seat support edge strip.
Background technology
Edge strip is generally placed in the both sides of seat support, and for providing support seat cloth and fix, it extends at seat support above-below direction, also can be used as the bracing frame of chair leg and backrest.
Authorization Notice No. is that the Chinese utility model patent of CN 202618986 U discloses a kind of seat support, wherein relate to a kind of side-strip structure, changing side-strip structure utilizes the bending part on edge strip top limit the projection on seat limit and fix, there is the simple advantage of structure, but because the projection on seat limit has larger activity space in the accommodating area of this edge strip inside, can there is relative displacement in seat support in use, fixed performance is not good, and cause the friction of seat and this edge strip thus, there is the hidden danger of seat edge wearing and tearing, use also uncomfortable.
Summary of the invention
The present invention will solve the problems of the technologies described above, thus provides a kind of seat support edge strip, and it has, and fixed performance is good, long service life, seat feel comfortable advantage.
The technical scheme that the present invention solves the problem is as follows:
A kind of seat support edge strip, offer the groove of strip, the cross section of described edge strip is the rectangle from a side indent, and described concave shape forms limited mouth at described cross section side, is formed between accommodating area at described cross-sectional interior.On between described accommodating area, the point-to-point transmission parallel with described side directions, distance is not less than the width of described limited mouth.
Described edge strip has the cross section that general frame is rectangle, the advantage of rectangle is to provide smooth and contact surface that is larger area for described edge strip and the thing be in contact with it are assorted, described thing is assorted can be chair leg, chair frame, seat, handrail also or use the people of thing to sit on or thing, make to take more comfortable, support more firm.For inserting the rod-like members being connected cloth seat between described accommodating area, between the cross sectional shape of described rod-like members and described accommodating area, cross sectional shape matches, prevent described rod-like members from deviating from from described edge strip, and further fixation is risen to described rod-like members.
Preferred as technique scheme, described edge strip is symmetrical about the perpendicular bisector of described side.
Symmetrical structure makes the center of gravity of described edge strip when fixing more steady, and when bearing the weight of occupant, stress distributes more even on described side-strip structure, thus adds ability to bear and the intensity of described edge strip.In addition, the easier machine-shaping of outward appearance symmetrical structure.
Preferred as technique scheme, between described edge strip accommodating area, the shape of cross section is circular arc.
Be conducive to the interior fully extension in described accommodating area of seat support cloth between the accommodating area of circular arc, cloth is better to the covering property of described rod-like members, and the distribution of stress on cloth is more even when stressed, is comparatively applicable to fabric easy to wear.
Preferred as technique scheme, between described edge strip accommodating area, the shape of cross section is positive n limit shape, 2<n<7.
To the larger seat material of intensity own, the shape between cross section accommodating area can be adopted to be the structure of positive n limit shape, the cross sectional shape of the rod-like members of its correspondence is also corresponding positive n limit shape.This structure makes relative displacement to occur between described rod-like members and described accommodating area, and fixed performance is more even better than cross sectional shape between described circular arc accommodating area.
Preferred as technique scheme, two rectangle corners of described edge strip cross section concave side are fillet.
Fillet is arranged in two of inner side edge matrix corners, is to prevent wedge angle from injuring human body in the mode of scraping or stinging, and also can prevent from cutting damage to seat cloth.
Preferred as technique scheme, the cross section side of described edge strip and the ratio of upper and lower edge lengths are 0.8/1-1.2/1.
Side and upper and lower length of side ratio will have a suitable scope, otherwise edge strip cross-sectional area is wide or long uses equal inconvenience.
Preferred as technique scheme, formed by deformation after ERW pressurized, the weld seam of described ERW is positioned at the inner edge between described accommodating area.
By weld seam as herein, be consider from two aspects, one is easy to process, and steel plate is after twisting, and the docking port that its symmetrical structure makes steel plate last and weld seam are positioned between described accommodating area just the most inwardly to be located; Another one aspect considers the stressing conditions of edge strip, take gravity load that people brings mainly by described edge strip upper below and side bear, the stress that between described accommodating area, the most inside place affords is minimum, consider that the intensity of commissure is comparatively weak, by weld seam as maximizing favourable factors and minimizing unfavourable ones to the full extent, improve the bulk life time of described edge strip herein.
In sum, the utility model has following beneficial effect:
Fixed performance is good: rectangular frame is better fitted seat miscellaneous part and take buttocks; The cross sectional shape of the accommodation space matched with described rod-like members cross sectional shape can fix seat preferably, can select between circular arc accommodating area and between regular polygon accommodating area depending on seat strength of materials size;
Long service life: symmetrical structure makes stress distribution even, position while welding is selected the most inwardly to locate meeting with stresses between minimum accommodating area, extends the service life of described edge strip;
Sit sense comfortable: the corners of suitable side and upper following ratio and matrix corner can make occupant obtain more comfortable ride experience.
