Description

Portable folding stool

The utility model is that a kind of being suitable for traveled or carried out the portable pocket faldstool that outdoor sports is used.

People travel outdoors or when carrying out the outdoor sports respite, total hope can find somewhere to squat at once, but often can not achieve one's goal, and therefore, people are going out often to like often being with a collapsible stool.So that can be seated rest at any time, but all now faldstool structures too greatly, too heavy, travel outdoors and carry very inconvenience, it is little, in light weight to lack a kind of volume, can be placed on the faldstool in the suit bag.

At the problems referred to above, the utility model has designed a kind of pocket faldstool of novel structure, and it has little, in light weight, stressed big, the convenient carrying of volume, struts and fold very nimble, very with practical value.

This pocket faldstool is made of soft cushion (1), upper rack posts (2), housing (4), force block (6), center-pole (9), body (10) and lower fulcrum bar (12), soft cushion (1) is fixed on the top of upper rack posts (2), the end in addition and the housing (4) of upper rack posts (2) flexibly connect, and upper rack posts (2) is that fulcrum can move with the steady pin (7) on the force block (6).Housing (4) can move by easy on and off outside body (10) and lower fulcrum bar (12).Fixedly connected with force block (6) with screw thread in the upper end of center-pole (9).Its lower end has screw thread and matches with the center screw of body (10).Center-pole (9) can freely stretch out body (10) or be contracted in body (10) central authorities.Lower fulcrum bar (12) is contained in the lower end of body (10), connects with bearing pin (11) interaction, can freely open or draw in.Pocket faldstool is under user mode, and its housing (4) is enclosed within outside the force block (6), and upper rack posts promptly struts automatically, makes soft cushion (1) become a plane.Center-pole (9) stretches out, and is fastened to each other with screw thread and body (10).Lower fulcrum bar (12) flare up stool pin can be sat the people; Under the folded state, center-pole (9) is contracted in body (10) and following support body (12) central authorities, and housing (4) is displaced downwardly to lower fulcrum bar (12) lower end, and upper rack posts (2) is that nature draws in and is integral.Because the novel structure that upper rack posts (2), housing (4), force block (6) and steady pin (7) are formed is to have used mechanics upper lever self-lock mechanism, upper rack posts is hinged together dexterously, forms a flexible freely and have the integral body of self-lock ability.Because of the FG arm greater than the EF arm.Housing after the people takes (4) and upper rack posts (2) can not glide.

Soft cushion (1) can be made into netted or be done by nylon cloth, cotton and become band or the monoblock cloth is made or inflatable packer by plastic ties or cotton cord.It makes the top in upper rack posts (2).Upper rack posts (2) is made by identical four or many strip metals bar, and bar central authorities have strip hole, and an end of bar has pin-and-hole, flexibly connects with pin (3) and housing (4), and extension spring (5) is housed makes the two tension.The profile of housing (4) can be done squarely or triangle, also can make polygon.Corresponding position on every limit has a pin-and-hole that protrudes.Flexibly connect with pin (3) and upper rack posts (2), the interior hole shape of frame should be consistent with the profile of force block (6), body (10) and lower fulcrum bar (12).The profile of force block (6) can be done squarely or circle, below the center have screw, fix with the screw thread of center-pole (9).Be equipped with on the force block (6) and bump button (14), this bumps button (14) body (10) is hooked when folding.Center-pole (9) is cylindrical, is made up of single-unit or telescopic more piece, and an end car has screw thread and force block (6) to fix, and other holds car that the coarse pitch multiple thread is arranged, and it has the multiple-threaded through hole of coarse pitch to match with the central car of body (10).When the profile of body (10) is done squarely, all have breach on four jiaos of its lower end, and be equipped with pin-and-hole, flexibly connect with bearing pin (11) and lower fulcrum bar (12), four lower fulcrum bars this moment (12) constitute the stool pin, when four poles were closed up, its profile was a square, was cylindrical hole in it, do when circular with the profile of placing center-pole (9), body (10), then its lower end folds and has three breach on 120 angles, and is equipped with lockhole, flexibly connects with bearing pin (11) and lower fulcrum bar (12).Be that three poles constitute the stool pin this moment, when closing up, is cylindrical inside and outside it, lower fulcrum bar (12) upper end has pin-and-hole, and tension spring (18) is housed, and it links to each other with body (10), lower fulcrum bar can be opened automatically, and button (15) is equipped with in one of them lower fulcrum bar lower end.When folding, housing (4) can be hooked.Pocket faldstool can be made by metal material or fiberglass or high-strength rigid plastics.

This pocket faldstool novel structure, it is in light weight, stressed big to have a volume little (one two joint of less than flashlight size when folding), characteristics such as is convenient to carry, and struts and fold very nimble.Be particularly suitable for travelling outdoors or use when carrying out outdoor sports.Simple in structure, easy to manufacture, with low cost.Support that by the going up of stool that upper rack posts, housing and force block three constitute the part primary structure is to have used the lever self-lock mechanism on the mechanics, upper rack posts is hinged together dexterously forms an integral body that has self-lock ability again capable of expansion and contraction, this overall structure is inverted, can become the support of telescopic type, utilize the support of this telescopic type can produce support series products such as tripod of new generation, music easel, microphone stand, clothes hanger, this series products volume is greatly reduced, weight saving is carried very convenient.

Below in conjunction with accompanying drawing the utility model is described in further detail:
