Abstract

The utility model relates to a stacked revolving chair which is a chair for daily life. Based on the existing stacking chair, a couple of plane rotation plates, or a clamping steel ball or a normalized universal bearing are added to a seat frame and a stacking base frame. Capable of being stacked and transported, the utility model has the functions of a revolving chair and is an ideal chair for people to use for work and rest.

Description

Stacked revolving chair

The utility model relates to family life articles for use, particularly seat.

In family, especially public places such as restaurant, the entertainment Room and small conference room all are extensive use of and pile up chair at present.Its characteristics are good than the rigidity of folding seat, are easy to moulding, can pile up when not using or in the transportation and deposit fortune, and the swivel chair that area occupied more generally can not fold is much smaller, but does not possess the rotatable function of swivel chair.In the prior art, patent document discloses collapsible swivel chair of many kinds and multifunction chair (CN87200697, CN88218399), the chair stool of its design all has collapsible, rotating characteristics, in order to solve the rotation problem, what have must manufacture and design a kind of nonstandard bearing, makes and be equipped with certain trouble, the axle sleeve that the central shaft that only depends on supporting that perhaps has inserts on the seat frame carries out, and rotary resistance is bigger.

The purpose of this utility model is exactly in order to solve the above-mentioned problems in the prior art, to provide a kind of manufacturing simple to people, rotating chair light and that can pile up, to satisfy the needs of people's life.

The utility model by can pile up underframe 1, seat framework 3, seat cushion 4 are formed, the A face that it is characterized in that having pair of planar swivel plate 2 to be separately fixed at and can pile up underframe 1 and the B face of a framework 3.Garden type groove is arranged on the plane swivel plate 2 one, clamping common steel ball 5, garden type step is perhaps arranged on the plane swivel plate 2 one, clamping standardized universal bearing, in order to bear gravity and rotation.Can pile up underframe 1 and seat being connected of framework 3, be the pivot hole by the pair of planar swivel plate, connects with regular screw threads, perhaps adopts riveted joint.

The utility model has solved the problem that chair can not rotate of piling up in use like this, compared with prior art, has both improved the resistance of rotation, has simplified making and mounting hardness again, is the desirable seat that people live, have a rest.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the schematic diagram of the utility model when piling up.

Fig. 3 is that the plane swivel plate is fixed on the schematic diagram that can pile up on the underframe.

Fig. 4 is the schematic diagram of the fixing present framework of plane swivel plate.

Fig. 5 is the side sectional view of plane swivel plate.

Fig. 6 be can pile up underframe with the seat framework the cutaway view that is connected.

At Fig. 1, Fig. 2, among Fig. 6, the utility model mainly is by piling up underframe 1, plane swivel plate 2, (the plane swivel plate is according to the steel ball that clamps or bearing decision geometry and size) steel ball 5, (perhaps standardized universal bearing, as single direction thrust ball bearing series) seat framework 3 composition, wherein on the seat framework seat cushion 4 is installed, it is an integral body that back of the body frame and seat frame can weld, and its M is slightly larger than N, so that pile up, these are all identical with the common chair design principle of piling up, Fig. 3 to Fig. 4 is that plane swivel plate 2 is fixed on the signal that can pile up on underframe 1 and the seat framework 3, and this fixing can be welding, also can be riveted joint.These two plane swivel plates, appearance and size can be different, but garden type groove or garden type step steel ball track must be identical, both can use the sheet stamping moulding, also machinable moulding.

From Fig. 5 to Fig. 6, if use plain ball 5, the section of the garden type groove on the swivel plate of plane is the garden camber, and its garden arc radius and steel ball radius match, if use standardized bearing, then are processed into step, locate in order to bearing.Like this utility model in use, the resistance of rotation improves, and has guaranteed the rigidity of axial support.Pivot have a through hole with screw rod 7 nuts 8 can pile up underframe 1 with the seat framework 3 be connected, simultaneously steel ball 5 some grains are clipped in the type groove of garden, mix up the gap of bearing, employing prevents the technology that nut unscrews, perhaps adopt riveted joint, the warp-wise displacement that these two kinds of forms can not limit in the time of can both overcoming the plane rotation.

Fig. 5 a, Fig. 5 b, Fig. 5 C are that the plane swivel plate is according to clamping several forms that steel ball or bearing adopt.Fig. 5 a is that plane swivel plate 2 adopts symmetry to clamp formula.Fig. 5 b is that the bicycle middle shaft bearing that plane swivel plate 2 adopts clamps form.Fig. 5 C is that the general bearing of plane swivel plate 2 accepted standardizations clamps form.

9 is standardized universal bearings among the figure, the 6th, and packing ring, φ are the motion locus of steel ball diameters.

Claims

1, Stacked revolving chair is by can piling up underframe 1, and seat framework 3, seat cushion 4 are formed, the A face that it is characterized in that having pair of planar swivel plate 2 to be separately fixed at and can pile up underframe 1 and the B face of seat framework 3.

2, Stacked revolving chair according to claim 1 is characterized in that piling up being connected of underframe 1 and seat framework 3, is the pivot hole by the pair of planar swivel plate, connects with regular screw threads, perhaps adopts riveted joint.

3, Stacked revolving chair according to claim 1 is characterized in that having on the plane swivel plate 2 garden shape groove one, is clamping common steel ball 5, and garden type step is perhaps arranged on the plane swivel plate 2 one, is clamping standardized universal bearing.
