Detailed Description

Embodiments of the present invention will now be described with reference to the accompanying drawings.

Examples

Detailed description of the inventionas shown in fig. 1 to 6, a portable cylindrical stool comprises a soft seat cushion 1 and a support member provided thereunder. When the user uses the cylindrical stool, the person sits on the soft cushion 1, and the soft cushion 1 is supported by the support component.

Wherein the support assembly comprises a vertically arranged mounting tube 4. A support tube 3 which can move telescopically is sleeved in the installation tube 4. The lower end of the mounting tube 4 is hinged with a plurality of supporting foot plates 6 which swing towards the direction far away from the axis of the mounting tube 4. The upper end of the supporting tube 3 is hinged with a plurality of supporting plates 2 which swing towards the direction far away from the axis of the supporting tube 3. The upper end of the supporting plate 2 is connected with the soft cushion 1.

When the folding cylindrical stool is stored, the support tube 3 which is moved in the installation tube 4 in a telescopic manner can vertically contract the height of the whole cylindrical stool. Meanwhile, the hinged supporting foot plates 6 can contract inwards, and the horizontal unfolding area of the lower part of the whole cylindrical stool is reduced. In addition, the soft cushion 1 of articulated backup pad 2 cooperation, backup pad 2 can drive soft cushion 1 folding when inwards contracting and accomodate, reduces the level on whole cylinder stool upper portion and to the area that expandes. Through these structures, this cylinder bench can very convenient folding accomodate, reduces its required space greatly, and convenience of customers carries. Moreover, because the supporting tube 3 can vertically move in a telescopic manner, the user of the cylindrical bench can also adjust the height of the cushion by himself or herself according to the use requirement by adjusting the telescopic movement amount of the supporting tube 3. It is convenient to use, is suitable for the user crowd of various figures.

Simultaneously, down be equipped with a plurality of draw-in grooves 31 from last on the 3 outer walls of stay tube in proper order, be equipped with the opening on the installation pipe 4 lateral walls, be equipped with the activity fixture block 41 with draw-in groove 31 joint in the opening. The engagement between the engaging groove 31 and the movable engaging block 41 can be used to fix the support tube 3 and prevent the support tube 3 from moving in the mounting tube 4. Since the engaging slots 31 are disposed in a staggered manner around the axis of the supporting tube 3, the supporting tube 3 can be axially rotated and adjusted relative to the mounting tube 4 during actual use, thereby achieving the purpose of rotating the soft cushion 1. Meanwhile, by arranging the plurality of clamping grooves 31 with different heights, a user can select the clamping groove 31 with a proper height to be clamped with the movable clamping block 41 according to actual needs, and the purpose of adjusting the height of the cylindrical stool is achieved. In this embodiment, there are two kinds of the locking grooves 31, including a square groove provided on the outer side wall of the middle portion of the support tube 3 and an annular groove provided on the support tube 3 near the upper end/lower end.

And, one side of activity fixture block 41 is articulated with the opening edge through articulated rod 7, has cup jointed torsion spring 8 on the articulated rod 7, and torsion spring 8's both ends are connected with fixture block 41 and opening respectively. Through torsion spring 8, cooperation hinge rod 7, movable fixture block 41 can break out from the opening under the circumstances that has external force, and movable fixture block 41 can contract back in the opening automatically under the circumstances of no external force control. Through the structure, a user can conveniently switch the clamping groove 31 clamped with the movable clamping block 41, and the movable clamping block 41 does not need to be integrally taken down every time.

In this embodiment, in order to ensure the beauty of the outer wall of the installation tube 4 and to prevent the fixture block 41 from falling off. An elastic ring sleeve 9 which is arranged around the axis of the installation pipe 4 and can cover the through hole is arranged on the outer wall of the installation pipe.

In addition, a limiting pipe 5 capable of moving up and down is sleeved on the outer wall of the lower part of the installation pipe 4. The lower end of the limiting pipe 5 extends to the outer side of the supporting foot plate 6. The inner diameter of the lower part of the limiting pipe 5 is 1.1 to 1.5 times of the inner diameter of the upper part thereof. Through setting up spacing pipe 5 to adjust the vertical high position of spacing pipe 5, can effectively restrict the angle that opens of backup pad foot 6, avoid it to open the angle too big.

And, be equipped with the external screw thread on the outer wall of installation pipe 4 lower part, spacing 5 inner wall upper portions of pipe are equipped with the internal thread with installation pipe 4 outer wall screw-thread fit. Threaded fit's installation pipe 4 and spacing pipe 5 have guaranteed that spacing pipe 5 can be stable install on installation pipe 4, can not remove at will, and then support that the board foot 6 can be stable fix and open the angle, the bench use also more stable. Meanwhile, the up-and-down movement distance of the limiting pipe 5 can be conveniently controlled, and the effect of accurately adjusting the opening angle of the supporting plate feet 6 is achieved.

The supporting foot plate 6 is an arc-shaped plate with the same shape as the outer wall of the mounting pipe 41, and the outer wall of the supporting foot plate 6 is provided with an internal thread matched with the inner wall of the limiting pipe 5 in a threaded manner. When the folding cylindrical stool is stored, the limiting pipe 5 can be moved to the supporting foot plates 6 to gather the supporting foot plates 6 together. And, through with 6 outer wall screw-thread fit of supporting legs boards, can guarantee the stability of spacing pipe 5 on supporting legs board 6, can not appear droing.

In this embodiment, the sectional area of the supporting foot plate 6 is gradually reduced from top to bottom. Of course, in the actual assembly process, the supporting foot plate 6 may also be a supporting foot plate 6 with a fixed cross section, and the cross section is not necessarily required to be gradually reduced, and may be determined according to the actual design.

It should be noted that:

the upper end of the supporting foot plate 6 is hinged with the lower end of the mounting pipe 41 through a hinge rod 7. The hinged rod 7 is sleeved with a torsion spring 8. The two ends of the torsion spring 8 are respectively connected with the supporting foot plate 6 and the mounting tube 41. Through the cooperation of the hinge rod 7 and the torsion spring 8, the supporting foot plate 6 can obtain an opening force and automatically open without constraint. The foot plates 6 need not be manually broken apart when unfolding the device.

The axle center in the soft cushion 1 is provided with a mounting block 11. The side wall of the mounting block 11 is also provided with a plurality of framework plates 12, and the two ends of the framework plates are respectively hinged with the mounting block 11 and the support plate 2. The upper part of the mounting block 11 is detachably provided with a gland 13. The framework plate 12 can act like the umbrella ribs of an umbrella, and the structural strength of the soft cushion 1 is improved, so that the soft cushion can bear larger pressure. Meanwhile, the pressing cover 13 is provided to prevent the skeleton plate 12 from being excessively opened.

When the cylindrical stool in the embodiment is used, a user sits on the soft cushion 1 and has a stretching force, and can stretch in four directions. The cylindrical stool is a high stool when rising, and is a low stool when being adjusted downwards and lowest. When the cylindrical stool is stored, the size of the cylindrical stool is the same as that of a water cup, and the cylindrical stool is convenient to carry. The upper part and the lower part are unfolded to form the cylindrical stool, so that the use is convenient.

The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, and is intended to cover various modifications, equivalent combinations, which are made in accordance with the spirit of the present invention.
