Abstract

A face-to-face recreational exercise bike and belongs to the field of fitness devices and is used for improving the leg function. Three telescopic links, two handrails, a connecting rod and four chain wheels, namely a first big chain wheel, a second big chain wheel, a first small chain wheel, a second small chain wheel, are fixed on a frame. The first small chain wheel and the second small chain wheel are mounted in a proper position and form an effective combination with the second big chain wheel. A chain forms a rotary loop through the two small chain wheels and the two big chain wheels. The second big chain wheel can reversely rotate through changing a surrounding mode of the chain on the big chain wheels and the small chain wheels. A hand brake can lead the chain wheels to rotate at a slow speed or stop. Both exercisers exert forces to tread pedal plates and simulate the action of riding a bicycle; and continuous rotation is realized through chain wheel combination, so that the exercisers continuously move legs and feet, thereby achieving the exercise purpose. Therefore, the face-to-face recreational exercise bike has remarkable effect on the improvement of lower limb function.

Description

Face-to-face leisure body-building vehicle

Technical field the utility model belongs to body-building apparatus.

Background technology is for the crowd of the body-building of having no time because of the busy often overtime work of working, or inhabitation building inconvenience crowd up and down etc., having been short of exercise for a long time causes motor tissue to ossify easily, poor blood circulation, the leg muscle atrophy, the training of therefore strengthening leg function is extremely important.But do not occur being specifically designed at this type of crowd the sports apparatus of leg exercises in the market as yet, the leg function that proposition Given this of the present utility model is strengthened the lower limb exercise crowd for needs improves significant.

The summary of the invention the purpose of this utility model provides a kind of sports apparatus that improves the shank illness that is specifically designed to.

Below structure of the present utility model and principle are described.This sports apparatus is made of frame, bottom bracket, covering, first expansion link, second expansion link, the 3rd expansion link, first seat, second seat, first handrail and connecting rod, second handrail and connecting rod, first pedal and connecting rod, crus secunda pedal and connecting rod, first sprocket wheel, second largest sprocket wheel, first minor sprocket, second minor sprocket, regulating wheel, chain, rim brake, brake cable, brake shoe, teapoy plate.Bottom bracket and frame are connected as a single entity, and three expansion links, two hinge wheels, two minor sprockets all are fixed on the frame.The expansion link bottom embeds frame inside, can adjust height within the specific limits.Two seats, two handrails and connecting rod, little table are separately fixed at three expansion link tops.First, second pedal is installed in respectively on first, second hinge wheel, and can keep with hinge wheel separately rotating synchronously respectively, and two pedals can freely rotate in connecting rod end separately.First, second minor sprocket becomes chain wheel set to close with second largest sprocket-shaped.Regulating wheel is drawn by first sprocket wheel.Chain forms and rotates the loop by two hinge wheels, two minor sprockets, regulating wheels.By change chain on large and small sprocket wheel around mode, can make second largest sprocket wheel to counter-rotation, form the backward rotation loop.Regulating wheel is adjusted the chain degree of tightness after being used for changing rotation loop direction.Covering is located at all sprocket wheels, chain outside, makes sprocket wheel, chain be in sports apparatus inside.Covering is easy to loading and unloading, change when conveniently needing chain around mode.Brake shoe is installed on the first sprocket wheel, and rim brake can make the sprocket rotation deceleration by brake cable or stop.Little table can be installed or unload as required.

The beneficial effects of the utility model are, adopt passive movement, drive the slow or rapid movement of shank by extraneous motion of mechanism, have a significant effect to improving, strengthen leg function.By changing the direction of motion, can carry out the leg exercises of positive and negative twocouese, realize with live at ordinary times in the opposite motion of habitual movement, reach better train on.Can place tea set, chess and card etc. on the little table, make the person taking exercise when taking exercises, carry out the amusement and recreation activity.

Description of drawings

Structure principle chart when accompanying drawing 1 becomes the forward rotation loop for the utility model is capable.

Structure principle chart when accompanying drawing 2 forms the backward rotation loop for the utility model.

The specific embodiment is following to be described structure of the present utility model and principle by the specific embodiment.

The utility model needs two people to use simultaneously, and two people lay respectively at the both sides of apparatus.During use, a people is sitting on first seat (7), holds first handrail (9), and pin is placed on first pedal (11); Another people is sitting on second seat (8), and hand steered second handrail (10), pin are placed on the crus secunda pedal (12).Temper both sides and firmly step on pedal, do imitation action by bike, by chain (18) drive first sprocket wheel (13), second largest sprocket wheel (14) rotates simultaneously.Chain (18) makes second largest sprocket wheel (14) to counter-rotation by first minor sprocket (15), second minor sprocket (16) and effective combination that second largest sprocket wheel (14) forms, and can making on both side, the opposite performs physical exercise with identical action.The in good time under-clad layer (3) that unloads in the exercise process, change chain (18) on the large and small sprocket wheel adjust around mode and by regulating wheel (17) chain (18) degree of tightness suitable after, the person taking exercise who is positioned on first seat (7) does same action, can realize crus secunda pedal (12) to counter-rotation, make the person taking exercise who is positioned on second seat (8) carry out with it the place ahead to opposite shank, foot motion.Little table (22) can be loaded onto or unload as required.By adjusting first expansion link (4), second expansion link (5) and the 3rd expansion link (6), can realize height respectively, use in order to the people who is fit to different heights to first seat (7), second seat (8), first handrail (9), second handrail (10) and little table (22).Rim brake (19), brake cable (20) and brake shoe (21) have been formed brake apparatus, take exercise if the person taking exercise thinks that velocity of rotation is too fast or wants to stop at once, can realize deceleration even stop the rotation of apparatus rapidly by rim brake (19).After adjusting the 3rd expansion link (6) height, can adjust brake cable (20) thereby the sensitivity of length assurance rim brake (19).In addition, this apparatus also comprises frame (1) and bottom bracket (2).The utility model is simple in structure, profile is small and exquisite, and whole apparatus length controlled is in one meter scope.
