Abstract

A casual fitness chair is provided, which is a quadrangle structure composed of a seat board, a front bracket, a back bracket and an underframe. The quadrangle structure is provided with two sets of spring components along the inclined downward direction. The shaft of the shaft bushing under a foot framework is arranged in the two shaft bushings of the underframe. The empty casing outside the shaft bushing under the foot framework is provided with an empty casing lever. The empty casing lever is movably connected with the pull rod of the foot framework and is also connected with a chain bypassing a pulley block. The other end of the chain is connected with a pin roll which is at the middle and lower part of the front bracket. When the user opens and steps on the foot framework, the empty bushing lever rotates and draws the chain, and beside, the front bracket conquers the elasticity of the spring components, which makes the seat board moving around the front and the back shafts of the underframe and rotating to a low-front and high-back situation. When the user relaxes the force slowly, the chair is restored to the initial situation under the action of the spring components. The body-building purpose is achieved.

Description

Leisure body-building chair

But the present invention relates to the chair of body-building in a kind of leisure, belong to furniture and fitness equipment technical field.

Chair generally is used for leisure, can not do body building; And the general family of fitness equipment does not possess the condition of buying and placing, and the sports apparatus that has lacks permanent attraction again, has become a kind of foreign material that are stacked at the corner in the course of time.

The purpose of this invention is to provide a kind of leisure body-building chair, chair and fitness equipment are combined, make people's body-building easily in leisure.

The object of the present invention is achieved like this: chair seat board, fore-stock, after-poppet, underframe pass through axle, and axle sleeve connects, and forms a quadrilateral structure, and the preceding back lower place of going up in the quadrangle is to passing through bearing pin, and bearing is equipped with main, rear spring assembly; Step frame Lower shaft sleeve is sleeved in the axle that passes two underframe connecting shafts cover, step frame Lower shaft sleeve is set with the sky cover of rotatable certain angle outward, sky puts installs free cover lever, be movably connected with step frame pull bar before the empty cover lever, the back links to each other with the chain of walking around pulley assembly, the chain other end links to each other with fore-stock middle and lower part bearing pin, like this when foot pedal when the front lower place depresses, seat support, backrest overcome spring assembly active force, rearward before underframe, rear axle does to meet the rotation of human body requirement, seat support becomes front end low, the rear end height, the people's is big, shank is the posture of stretching substantially, as long as loosen exerting oneself of pin slightly, under the effect of spring assembly, chair just restores to the original state.

Owing to adopted such scheme,, become 45 degree angles approximately with fore-stock as long as the people who is sitting on the chair opens the step frame, with pin foot pedal is stepped on to the front lower place, stretched both feet, pin slowly loosens and firmly gets back to original position again then, so repeatedly, just play the effect of body-building.During not body-building, can with the folding and unfolding of step frame before fore-stock, have a style of one's own with chair.

The present invention is further illustrated below in conjunction with accompanying drawing:

Fig. 1 is the side view of leisure body-building chair.

Fig. 2 is the vertical view of Fig. 1 below underframe.

Fig. 3 is the front elevation of forward and backward support.

Fig. 4 is the expanded view of step frame.

In accompanying drawing 1, seat support 17 following center fixed have chair plate undersetting 16, are connected with rear spring assembly 14 front end bearing pins, and rear spring assembly 14 rear ends are connected with after-poppet middle part bearing pin; Forward and backward under the seat support respectively have two bearings 23,30.Pass forward and backward support Upper shaft sleeve 24 (Fig. 3) with axle, be fixed on forward and backward two

bearings

23,30 separately.The Lower shaft sleeve 22 (Fig. 3) of forward and backward support is set on underframe (preceding) rear axle 12, and four are equipped with bearing or axle sleeve, and chair seat board, fore-stock, after-poppet, underframe are formed mobilizable four limit type structures like this; Main spring assembly 10 front end bearing pins are connected fore-stock central post 13 tops, the lower end bearing pin is connected on the underframe bearing 31, and underframe (preceding) rear axle 12 is fixed with the underframe axle sleeve respectively, the axle two ends are set with axle head sheath 20 (Fig. 2), and the axle head sheath has foot pad ground connection 20 times; Step frame Lower shaft sleeve 26 (Fig. 4) is contained in the two underframe connecting shafts cover 21 with axle sleeve, carrying wheel 6 is divided in two underframe connecting shafts and overlaps 21 outsides, outer sky cover 25 (Fig. 4) that are set with rotatable certain angle of step frame Lower shaft sleeve 26 (Fig. 4), sky puts installs free cover lever 7 (Fig. 1), be movably connected with step frame pull bar 5 before the empty cover lever 7, empty cover lever rear end links to each other with the chain of walking around pulley assembly (rope or belt) 8, and the chain other end links to each other with the middle and lower part bearing pin of fore-stock column 13.The lower end of step frame upper arm 2 is connected with the axle that passes step frame ratchet 28, two step frame axle sleeves 3 (Fig. 4), step frame ratchet 28 (Fig. 4) is connected with axle, rotation step frame upper arm 2 under ratchet 27 effect of (below), can regulate the front and back position of foot pedal 29, to adapt to the needs of user's position.When depress foot pedal 29 to the front lower place, the empty cover of step frame pull bar 5 pullings lever 7 on the step frame, drive chair seat boards 17 and after-poppet by chain (rope or belt) 8 pulling fore-stocks and overcome elastic force main,

rear spring assembly

10,14 and make seat board 17 move into low early and high after posture backward around underframe (preceding) rear axle 12, pin loosens slightly slowly and then is returned to original position.Step frame upper arm 2 can be around middle axle sleeve 3 inside rotary foldings during not body-building, with the underarm folding and unfolding before fore-stock, the rear.

Underframe in the accompanying drawing 2 is an individual layer, and promptly axle head sheath 20 is enclosed within the two ends of underframe (preceding) rear axle 12, contacts with ground; Underframe (preceding) rear axle 12 can be a minor axis, and square tube (or the garden pipe) two ends of burn-on below two underframe connecting shafts covers, 21, two rear axle housings 32 long (about 500) put foot pad and contact with ground, are double-decker.

The chair on accompanying drawing 1 top has handrail, also can also can adorn rota-cline seat without handrail.
