Abstract

The utility model relates to a seat cushion. A flexible base cushion is formed by the connection of a plurality of cancellate net strips on the outer side of the top end of a circular covering seat and frame edges. The top end of the inner hole of the circular covering seat is inward and convexly provided with a downward chamfered micro arc edge, and the bottom of the inner hole of the circular covering seat is inward and convexly provided with a ring edge. An oblique arc groove is arranged on the edge ring of the outer top of the cylindrical base seat of the lower end of a mushroom-shaped bead body which is provided with a groove with a suitable depth. The base seat is embedded in the inner hole of the circular covering seat in the mode of rotation. The micro arc edge of the circular covering seat is clamped in the oblique arc slot of the bead body to form clamping position. The base seat of the bead body is blocked by the inward and convexly provided ring edge of the inner hole of the circular covering seat, and the practical effects of easy assembly, stable positioning and desquamation prevention are achieved.

Description

Cushion

The utility model relates to a kind of quick-mounting formula seat cushion; It reaches the practical function that assembling is easy, locate firm anticreep in the mode of embedding, blocking.

The major function of chair cushion is intended to prevent that the seat or the chair back from producing stained because of often sitting the pressure use, so that easy cleaning or renew not, and every placing the seat between person and chair tool, then can provide more comfortable seat sense and good gas permeability by chair cushion, make the long-time seat person of leaning on no longer include extremely hot hard to bear impression; So generally regarded with affection by the consumer, and be widely used in Indoor chair or automobile seat support covering use.

At present except concatenation type is arranged, outside the knockdown wooden pearl chair cushion, other has with the pearl body and all puts direct location mode at net strip base wad, please cooperate and consult Fig. 1, a kind of seat cushion neotectonics shown in 2, mainly plane and by the net 1 of the grid 12 that generally is square that net bar 11 constitutes in length and breadth by one, in this grid 12, insert cushion block 2, this cushion block 2 is corresponding up and down and generally is circular arc termination 21 for having, 22 bullhead structure, therebetween then for cooperating the neck 23 of grid 12 sizes, can select a

termination

21 or 22 arbitrarily and insert in the grid 12, and must any auxiliary object can directly not finish combination with pad.

But its structure still has several following disappearances to exist, because each is variant for the hardness that different glue materials are presented, because of reaching normal location, so the material of net 1 will have certain pliability, could make things convenient for, make easily cushion block 2 to be distributed on the net 1 with cushion block 2

terminations

21 or 22 prominent grids 12 more; Yet when net 1 provides cushion block 2 rapidly during the location with the texture of dead-soft, it relatively also causes cushion block 2 (pressing inequality to make the stressed cushion block 2 that makes of net 1 crimp deviate from grid 12 because of the sitting) phenomenon that easily comes off, and a firm polarization can't be arranged; Double end as for cushion block 2 becomes circular-arc, only has point-like to contact with seat, therefore, have different and produce nondirectional rocking when sitting pressure, so that 2 of cushion blocks becomes the inclination angle contact, and then crush the stern meat of human body; In addition, when cushion block 2 shuttles back and forth in grid 12, affect 11 one-tenth of peripheral net bars the pulling and draw in the same way not that constitutes grid 12, because net bar 11 is quite very thin, it is soft to fit, really be difficult to bear pull and draw and sit and press distortion stressed, so that produce the brashness of net bar 11, destroy the integrality of whole net 1, it serves to show that this conventional construction still remains to be improved.

In view of this, the purpose of this utility model is to provide a kind of seat cushion, and it reaches the practical function that assembling is easy, locate firm anticreep in the mode of embedding, blocking.

For achieving the above object, the seat cushion that the utility model provides is mainly put with architrave with several companies that justify the grid network bar that extends outside block set tops and is formed flexible base wad, this circle block set endoporus top is inwardly prominent sets the differential of the arc edge of cutting sth. askew, and the ring edge inwardly is equipped with in the bottom in the hole; Cylindrical base outside apical margin with mushroom shape pearl body lower end of suitable dark groove is equipped with oblique arc groove, base is embedded in the endoporus of round block set in the rotation mode of pressing down, so that the differential of the arc edge of base snaps in the interior blocking location that forms of the oblique arc groove of pearl body; Reach the practical function that assembling is easy, locate firm anticreep.

In addition, the ring edge inwardly is equipped with in the bottom in circle block set hole, so that mushroom shape pearl body base fended off by the ring edge, in case when terminating in the extrusion of seat cushion bottom and mushroom shape pearl body is pushed ejection.

By said structure, the utility model is made and pearl body assembling mode with the element of simplifying, and reaches the effect that reduces manufacturing cost, promotes the market competitiveness.

Base wad of the present utility model becomes the wide shape of plane formula contact with several circle block set bottom surfaces with chair tool surface, and the location that whole chair cushion is covered put on the chair tool is quite steady, can stop to cause the generation that crushes situation because of sitting the pressure inequality.

Now again with regard to architectural feature of the present utility model and operation etc., in the mode of conjunction with figs. explanation, detailed row record and narrate in after.

Fig. 1 is the floor map of conventional construction.

Fig. 2 is the combination dissected figure of conventional construction.

Fig. 3 is a three-dimensional assembly diagram of the present utility model.

Fig. 4 is a part three-dimensional exploded view of the present utility model.

Fig. 4 A is the stereo dissected figure of mushroom shape pearl body of the present utility model.

Fig. 4 B is a part combination dissected figure of the present utility model.

At first, see also shown in Fig. 3,4, the utility model is made up of flexible base wad 3 and several mushroom shape pearl bodies 4; Wherein, the company of the grid network bar 31 that is extended by several outsides, circle block set 32 tops puts with architrave 33 and forms this flexible base wad 3, and inside the dashing forward in these circle block set 32 endoporus tops set the differential of the arc edge 321 of cutting sth. askew, and the bottom inwardly is equipped with and is encircled edge 322 in the hole; Cylindrical base 41 outside apical margins of these mushroom shape pearl body 4 lower ends are provided with oblique arc groove 411, and there is suitable dark groove 412(the bottom shown in Fig. 4 A, 4B).

See also shown in Fig. 4 B, base 41 by mushroom shape pearl body 4 embeds in the endoporus of round block set 32 easily in the rotation mode that presses down, so that the differential of the arc edge 321 of circle block set 32 snaps in the oblique arc groove 411 interior blocking location that form of mushroom shape pearl body 4 bases 41, and mushroom shape pearl body 4 is all constituted seat cushion fast, easily admittedly on base wad 3, with the ring edge 322 of justifying bottom in block set 32 holes mushroom shape pearl body 4 bases 41 are fended off, in case when terminating in the extrusion of seat cushion bottom and mushroom shape pearl body 4 is pushed ejection; Reach the practical function that assembling is easy, locate firm anticreep.

In sum, the utility model is to improve the usability of known seat cushion, has firm, the easy practical effect in location really.
