The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Structure of the present utility model is seen Fig. 1-shown in Figure 180, Undercarriage structure 10, fore-stock 11, after-poppet 12, cross bar portion 111,121, two ends 111a and 121a, straight-bar portion 112,122, buffer stopper 113, joint seat 13, underframe angle adjustment jack 131, back bracket angle adjustment jack 132, folding jack 133, seat portion 15, first latch 16, second latch 17, handle structure 20, lever 21, stationary pipes 22, fixing hole 22a, sleeving connecting rod 23, sleeve 231, adjust hole 23a, the 3rd latch 24, back bracket structure 30, microscler pole 31, bow 32, cushion 33, short strut 34, the headrest 35, pivoted pole 36, flexible member 37, bobbin 38, elastic threads 40, foot rest 50, backguy 60, ring portion 61
Referring to Fig. 1 to Fig. 3, back provided by the utility model extensional motion machine is to provide the user back to make extensional motion, and it is constituted with a Undercarriage structure 10, a handle structure 20 and a back bracket structure 30.
Wherein the combination of Fig. 6 the 3rd latch 24 makes lever 21 near seat portion 15, and the combination of Fig. 7 the 3rd latch 24 makes lever 21 medium from seat portion 15, and the combination of Fig. 8 the 3rd latch 24 makes lever near seat portion 15.This design can conveniently not be adjusted to the appropriate location simultaneously for the user is pushing.
When using the utility model, earlier referring to Fig. 4, user's buttocks is seated on the seat portion 15, the both hands branch is held two levers 21 in handle structure 20, the back back bracket structure 30 that reclines, and utilize and to pull the reaction force that pushes away or layback strength (shown in arrow among Fig. 4) is bestowed at foot-operated and back, make back bracket structure 30 rotate with stretching user back, referring to shown in Figure 5 with pivoting point.In this layback strength when cancellation, but because the restoring force that flexible member 37 provides and the labour-saving returns back to former sitting posture gesture shown in Figure 4.
In addition, the straight-bar portion 112 of fore-stock 11 has a buffer stopper 113, to keep out microscler pole 31 bottoms of back bracket structure 30.
Be the person's of being used height difference, and be provided with guiding mechanism at Undercarriage structure 10, it has mainly offered most underframe angle adjustment jacks 131 on joint seat 13, and can select to insert in those underframe angle adjustment jacks 131 with one first latch 16.Each underframe angle adjustment jack 131 can pass straight-bar portion 112 ends of fore-stock 11 after first latch 16 inserts, to adjust and fixedly the straight-bar portion 112 and the 122 relative opening angles of fore-stock 11 and after-poppet 12, use and adjust the high height of portion that rises, can be referring to comparison diagram 4, Fig. 9 and shown in Figure 10.Wherein the block position of Fig. 4 first latch 16 makes that joint seat 13 and ground gap are the highest, and Fig. 9 is then to medium, and Figure 10 is then to minimum.Open for providing Undercarriage structure 10 to adjust angles that (as shown in figure 10) has more firm contacting to earth property when big, be provided with a cushion block 18, when opening, contact to earth with cushion block 18 at straight-bar portion 112 downsides of fore-stock 11.
The person of advancing causes stretching angle difference, back bracket structure 30 can adjust it and stretches maximum angle for the person of being used back pliability is different.Mainly on joint seat 13, have most back bracket angle adjustment jacks 132, and can select to insert those back bracket angle adjustment jacks 132 with one second latch 17.Each back bracket angle adjustment jack 132 can be kept out the pivoted pole 36 of back bracket structure 30 after second mortise lock slotting 17 is gone into, with the angle of inclination of adjusting and limiting this back bracket structure, can compare Figure 11 and shown in Figure 12.Wherein the block position of Figure 11 second latch 17 makes that the angle of inclination of back bracket structure 30 is less, and the block position of second latch 17 makes that the angle of inclination of back bracket structure 30 is bigger among Figure 12.This is designed to prevent that excessive stretching from causing on the contrary that the user's is injured.
Smooth in order to reach extensional motion, at each short strut 34 of bow 32 both sides of back bracket structure 30, have a bobbin 38 in the cushion 33 of socket on it, it is to can be the plastic material manufacturing, makes cushion 33 to rotate relative to short strut 34.This design makes that when extensional motion the user back can should be cushion 33 rotations and adjust displacement automatically, reaches the effect at massage back simultaneously.
Referring to Figure 13, be the folding situation of the utility model.When folding, as long as earlier flexible member 37 is untied an end earlier, and first latch 16 is detached underframe angle adjustment jack 131, Undercarriage structure 10, handle structure 20 and 30 foldings of back bracket structure can be become position shown in Figure 13; And then, can reach fixedly folding situation with the folding jack 133 of first latch, 16 insertion joint seats 13 and the perforate of passing fore-stock 11, and convenient harvesting, reverse operating is deployable when treating next the use.
Back provided by the utility model extensional motion machine can be done some simple changes and can become the sports equipment at other position of health on its structure.
Referring to Figure 14, the utility model is designed to rotary type with seat portion 15, handle structure 20 then is arranged in the straight-bar portion 112 of foot rest structure 10 the place ahead fore-stocks 11, so change, the user can be got down on both kneels on this seat portion, both hands are gripped on lever 21, and rotatable waist and buttocks (shown in arrow among the figure), to reach waist stern motion machine.
Referring to Figure 15, similar shown in Figure 14, the utility model also can be further below the handle structure 20 of being located at the place ahead and one group of elastic threads 40 of 10 installings of Undercarriage structure, elastic threads 40 handle structure that provides 20 pressure are provided, then the user can be seated on the seat portion 15, utilize belly strength push-and-pull handle structure 20 (shown in arrows among the figure), to form an abdominal movement machine shape like boating.
Again as shown in figure 16, the utility model also can be provided with the high foot rest 50 that rises of a leading edge below seat portion 15, and the user is seated on the seat portion 15, and both feet are surely stepped in these foot rest 50 leading edges, then do not need handle structure, can make the back extensional motion.
And Figure 17 is another variation of Figure 16, mainly at seat portion 15 rears one group of backguy 60 is set, and the user is seated on the seat portion 15, and both feet are surely stepped in foot rest 50 leading edges, grips the ring portion 61 of backguy 60 ends again with hand, can form an arm myokinesis machine; So the utlity model has the effectiveness of multi-functional.
In addition, shown in Figure 180, it is identical to embodiment shown in Figure 3 with Fig. 1, but in the straight-bar portion 112 of support 11 before the foot rest structure 10, set up a stationary pipes 22, this design, system is selected before or after the lever 21 of handle structure 20 is installed on for the user, and this be that another kind of simple variation of the utility model designed.
Again, as Figure 15 and shown in Figure 17, the two ends of this elastic threads 40 system utilizes snap joint to link, and so, can carry out conversion different ring portion 61 or any equipment that grips with user's demand, is beneficial to user's operation.
To sum up institute is old, and back provided by the utility model extensional motion machine is the complete structure of novelty, and has possessed advantage such as adjustable, safe, easy folding, meets patent requirement fully, hence files an application in accordance with the law.
Most preferred embodiment of the present utility model is illustrated, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
