At present, known tricycle is the usefulness of riding instead of walk, and fitness equipment is the exercise usefulness that fixes, the two all need pay strength, all want holding time and space, and these aspects can be unified or take into account to a great extent, but the two is unrelated now.

Purpose of the present invention is exactly to realize unifying or taking into account of the two, on tricycle, realize integrating body-building, amusement, riding instead of walk, can be in the indoor body-building that fixes, amusement, can in moving, do body-building, amusement again or advance fast, and can other purposes of double as.

The object of the present invention is achieved like this:

One, structure: see accompanying drawing P2 Fig. 2, P3 Fig. 3.On tricycle two rear-wheel hubs, respectively be equipped with one and overlap independently ratchet 10,10 inner ring is fixed on the wheel hub and (wheel is housed) on the wheel hub, 10 outer ring is connected with twisted wire wheel 9, then better as directly ratchet outer ring and twisted wire wheel being made one, connecing axle 12 with wheel hub again connects left and right sides wheel hub by bearing pin (or square tenon), twisted wire wheel 9 is made two parts at width, a part is drawn after twining a few on wheel week after being used for articulating drag-line 14 in the direction of the clock, the connection of exit is decided on purposes, another part also by clockwise around to articulate on wheel week that chest expander 19 draws around rope.The twisted wire wheel and the structure of chest expander by combining around rope of this band ratchet, the reciprocal rotary oscillation that has constituted this car is put the cable-styled transmission mechanism of receipts, also is the break-in governor motion of chest expander spring force simultaneously.

Connect axle 12 two ends at wheel hub,, radial ball bearing 8a is housed by bearing block assembly 8, (bearing block assembly 8, comprising bearing block 8b, radial ball bearing 8a, following seat surface door 8c with two seat surfaces) 8 last seat surface and the vertical rod of vehicle frame 2 fix, be with chest expander peg 20 in the vertical rod, (locating by the gong silk that holds out against in the vertical rod) is used for hanging chest expander 19 and regulates its height, and the middle part of vertical rod is shaped on the card frame, be used to adorn seesaw, be shaped on raceway on the crossbeam of vehicle frame 2.Be used for pacifying and go into seat 6, the crossbeam middle part is shaped on pulley card frame, (back) and rocking chair card frame (preceding), and vehicle frame is anterior and leading, the front fork connection, front fork is connected with preceding control device assembly 5 with front-wheel 4 by front axle; Chair frame lever assembly 7 (being made up of chair frame lever 7a and screw locking back-up ring 7b) is equipped with by bearing in the middle part that connects axle 12 at wheel hub, 7 front end is stretched between vehicle frame two crossbeams, chair frame roll sleeve on the abutment chair 6 rolls across thereon, and 7 rear end is with left and right sides loop bar 16 respectively; On the following seat surface of bearing block assembly 8, pulley hack lever assembly 13 is housed (by pulley hack lever axle 13a by bearing block shelves lid 8c, bearing 13b, pulley hack lever 13c and peg 13d form), 13 rear end is shaped on pulley card frame, be used for for changing the outfit pulley 15 usefulness, pull bar chair 18 is equipped with at 13 middle part, by 18 in vehicle frame 2 vertical rods connection and locate, also can be used to articulate on 13 and serve as shelf behind the netting and use.When taking off pulley hack lever assembly 13 and loop bar 16, move on in the card frame of vehicle frame 2 vertical rods fixing, pin assembly 23 was (by pin frame 23a before front end connected, pin axle 23b, rubber roll sleeve 23c, foam roll sleeve and viscose glue fabric width 23d form), seesaw has just been formed after having articulated drag-line 14 in the rear end, can forward and reverse dress crank handle 3 on pulley 15, insert boosting-rod 22 at chair frame lever assembly 7 front end lever Guan Zhongke.Above structure and Position Design have guaranteed position and annexation by some member of conversion, just can obtain multiple driving, manipulation, body-building, entertainment way.

The brake of this car can be adopted the mode of stopping two steel rim of rear wheel, and the brake lever that connects with wire is contained on the tap figure part omitted.

The general location size of car is seen accompanying drawing P4 Fig. 4.P6 Fig. 7

Two, operation principle: the difference of at first looking purposes is determined the radical of chest expander spring and the size of initial pretightning force, after regulating, when clockwise pulling drag-line, the twisted wire wheel is clockwise, drive inner ring and rotate by ratchet outer ring, ratchet, inner ring is fixed on the wheel hub, thereby drive the wheel rotation, owing to being connected in same wheel hub, two wheel hubs connect on the axle 12 again, so as long as one of them twisted wire wheel is clockwise or two twisted wires wheel clockwise two wheels that all can drive of while change simultaneously, and two twisted wires wheel is because the effect of ratchet, not influence each other; The twisted wire wheel is in rotation process, chest expander is done forward to reel around rope, and the drag-line stroke is big more, and chest expander is also big more around Suo Hangcheng, be that the length that drag-line is drawn out equals the length that chest expander is reeled around rope, chest expander spring elongation, move the position to after, pulling force disappears, the twisted wire wheel is being with under the spring force effect and is being reversed, spring reset, its result makes drag-line by rolling-in again, and can not drive wheel hub during reverse changes.Draw, put once, finish a working cycles.The size that changes spring radical and initial pretightning force just can reach different purposes.

Three, duty explanation:

Can be divided into by the application target difference and to ride instead of walk, body-building, three kinds of states of amusement, by selecting the suitable spring radical and the size of initial pretightning force (initial pretightning force is regulated by the initial length that changes between chest expander two articulated ends), can adapt to the requirement of different conditions, as when riding car instead of walk, spring should only keep one softer, initial pretightning force is very little, and promptly drag-line is after taking up on the twisted wire wheel, and its exit is under situation about not being pulled, the spring of reeling with wheel should be in relaxation state substantially around rope, along with drag-line outwards spurs, just by inwardly rolling-in, its elastic force is as long as guarantee that the drag-line return is (during return around rope, the reverse idle running of ratchet, the power of need is little), and under body-building and amusement state, spring radical and initial pretightning force are then selected as required.

Move and fixing two states whether fixing can being divided into by car, only need docking station frame 11 on the following seat surface of bearing block assembly 8, make wheel liftoff, the body-building recreation under the state that can fix.

Press pulley 15, the different allocation positions of member on vehicle frame such as pulley hack lever assembly 13 and crank handle 3 be connected, can obtain multiple driving and body-building state, existing be illustrated by this.

1, P4 Fig. 4 is seen at pulley 15 the is changed the outfit rear portion of car, and at this moment, pulley 15 is in the pulley card frame that is contained on the pulley hack lever assembly 13, and loop bar 16 is enclosed within the chair frame lever assembly 7 rear end levers, has articulated drag-line 14 on 16.On the crossbeam of vehicle frame, put seat 6 and can carry out the general exercise, using method is, the people is sitting on the seat 6, and two legs are clamped the seat, and two hold handlebar, bipod protracts, after stepping on the residence face, dial backward and pedal ground, seat will move forward, chair frame roll sleeve is pressed on the chair frame lever 7 and rolls, make the lever front end downwards and the rear end upwarps, the pulling drag-line makes the wheel rotation, after putting in place to the seat reach, people's pin has also moved on to the rear side of health (in the moving process, the wheel actual people's of being subjected to pedal ground and lever upwarp the effect of these two kinds of power of pulling drag-line) at this moment, pedal ground more suddenly, lift leg pin is placed on the preceding control device 5, after pedal and make the seat return, then lever resets under spring tension and deadweight effect, and the reel reversing is tightened up drag-line again, repeat this process, obtain the whole body exercise in the walking.During fixing the exercise, only need on the following seat surface of bearing block assembly 8, connect the station frame, make wheel liftoff after, by selecting the spring force assurance.

2, pulley 15 is changed the outfit on the pulley yoke of vehicle frame forefront, see P5 Fig. 5, the drag-line exit is connected handle 21, or crank handle 3 received on the pulley, again drag-line 14 exits are received its lower end, can pull back, or crank handle backward, pedal the driving and the body-building of three kinds of modes of handle, at its lower end forward with pin, fix when taking exercise, can also draw forward, can do such as swimmer's land practice equipment with (both hands can alternately draw, can draw simultaneously, temper arm strength; The people lies prone downwards and bows, and two drag-lines are hung on the bipod, and curved shank can be made leg exercises, and during fixing the exercise, the Zhi Haozhan frame has been covered front-wheel with cleat).

3, pulley 15 is changed the outfit in the pulley card frame on the middle beam of vehicle frame 2, the drag-line exit still connects handle 21, P5 Fig. 6 or receive the lower end (this moment roller arm by chair frame lever assembly 7 seat 8 is spacing) that tuning is installed in the crank handle 3 on the pulley 15 can do the driving and the exercise of pedal drag-line and hand crank handle dual mode.During fixing the exercise, also can face upward as the people and lie in ground, two hands are upwards held handle, are spurred by the place ahead to head, back.Or drag-line hung on the pin, upwards lift the leg pulling; Or human body is perpendicular to wheel, faces upward or bows on ground, handle is enclosed within makes side draw on the pin.

4, pulley hack lever assembly 13 is removed (seeing P6 Fig. 7) from following of bearing block assembly 8, on move on between two vertical rods of vehicle frame 2, be fixed on the vertical rod card frame, behind the loop bar 16 preceding lever 23 is inserted in 16 on its front end sleeve, with the Luo bolt the two is fixed, the rear end has articulated the exit of drag-line 14, pull bar chair 18 is installed on the loop bar 16 again, roll sleeve on the pull bar chair 18 will roll along loop bar 16, and the Luo bolt below it plays position-limiting action.Formed the seesaw car like this, the seesaw car has two kinds of usings method: one, make the amusement motor-tricycle, first regulating spring radical and initial pretightning force.Make the front end of seesaw seat obtain certain dynamics that upwarps, the size of initial pretightning force should guarantee that after pull bar chair 18 slides to the fulcrum place human body weight can not be depressed the lever front end.During action, the people is sitting on the pull bar chair, holds tap and draws forward, make the pull bar chair slide to front end, the center of gravity reach makes the seesaw rear end upwarp the pulling drag-line and turns a wheel, after running into vehicle frame to front end, two legs bending land, and pedal ground backward suddenly, health is swung back thereupon, seesaw is under the spring force effect, and front end upwarps, and makes pull bar chair 18 slide to the rear end again, move after the center of gravity, people's pin built on stilts can not depressed front end yet.In this process, when the seesaw front end is pressed down to the frame cross position, can remain on this position.People's pin is pedaled ground after repeatedly, to car certain speed is arranged after, the health of swinging back again makes the seesaw return.Its two, see that P6 Fig. 7 places pulley 15 correct position of the pulley card frame of vehicle frame 2 front portions, and connect crank handle 3.Hang a high-intensity tightrope in its lower end, the other end of rope is articulated on the same position of twisted wire wheel 9 around rope with chest expander, also need add certain initial pretightning force.Make seesaw that certain dynamics that upwarps be arranged.During action, the people is sitting on the pull bar chair, hold tap, before draw, make pull bar chair 18 slide to front end, the gravity of health is depressed the seesaw front end, and at this moment people's pin is placed on the pedal of crank handle 3 lower ends, but does not exert all one's strength, along with the seesaw rear end upwarps drag-line pulling wheel, the rotation of twisted wire wheel makes crank handle stay cord and chest expander reel around Suo Yiqi, and this moment, people's strength still was used in buttocks, and pin is only along with crank handle is swung backward, one runs into crossbeam until the seesaw front end, at this moment, begin to exert all one's strength with pin again and pedal the crank handle lower end forward, health is swung back naturally, the result of its comprehensive function, make on the one hand and move after rolling centre of body weight behind the pull bar chair, stay cord hauls the twisted wire wheel and reverses on the one hand, makes the drag-line band seesaw rear end return downwards again.Finish once circulation, indoor when doing this motion, should be with preceding control device assembly 5 accent faces dresses (making steamboat the place ahead) or uncomfortable at front axle, all with ratchet with the steamboat card earthward to increase weight capacity.

As take off pull bar chair 18 on seesaw, cover serves as the seat with canvas at two ends.Can make seesaw; As whole canvas or the netting of putting on seesaw, periphery is pulled on netting, and front end is fastened with rope band spacing on vehicle frame, with regard to children's's Cheng Liao shaking table; Seat 6 is tightly gone up divider, child can be placed on the seat again, come with pushing back movingly by the adult, make slide chair and use.

5, pulley 15 is installed in the suitable card chord position of vehicle frame 2 front portions, install left and right sides crank handle 3 at face of pulley, in the rocking chair card frame of vehicle frame 2 crossbeams, load onto rocking chair bearing 17a, again rocking chair seat 17b is inserted on the 17a pipe, tighten and hold out against Luo silk 17c, see P7 Fig. 8, prop station frame 11, choose spring radical and initial pretightning force, left and right sides drag-line 14 is articulated on the chair back cross bar of rocking chair, at this moment, after being pulled to, rocking chair leans against in the vertical rod of vehicle frame 2, then with the lower end of left and right sides crank handle 3 backward (upper end forward, divide with the direction of advance of car before and after) move on the whole crank handle axis position parallel with the predetermined axial location that arrives of rocking chair, with restricting or belt connects it with the brace that is connected the cross bar two ends under rocking chair 17 seats.During action, pin is placed on the suitable pedal in crank handle 3 lower ends, holds the handle of upper end, or emphatically with pulling, or use pedal emphatically, and the lower end of crank handle 3 is swung forward, drive rocking chair 17 by stay cord and swing (being that move toward one another is made with rocking chair in the crank handle upper end) forward.Chair back cross bar will be with drag-line 14, and twisted wire wheel is rotated, the elongation of being reeled of the spring on the left and right sides chest expander 19, after action puts in place (see P7 Fig. 8, position shown in the double dot dash line, the distance of pulling is random), stop firmly or during firmly less than spring force, rocking chair 17 and crank handle 3 are all with return.Arm, leg and belly are tempered in repetitive operation.Move when using, only need to hold on leading handlebar to get final product.

6, make disabled person's car and can adopt three kinds of type of drive.(1) in chair frame lever 7 front tube, inserts boosting-rod 22.(2) pulley 15 is fixed in the card after being positioned on vehicle frame 2 crossbeams, the following termination drag-line exit of dress crank handle 3,3 on the pulley.(3) pulley 15 is positioned in the suitable screens of card frame of vehicle frame 2 front portions, connects the drag-line exit with handle 21; All be with a palm to, a crank handle or handle.Disabled person's the both hands or the exercise of single leg then are same as the normal person.
