The specific embodiment

Consult Fig. 1, fitness equipment 10 has a mat 12, a pair of handwheel 14 and a pair of stretchable elastic strip 16.Each root tensile bars 16 links to each other a handwheel 14 with mat 12.Tensile bars 16 has produced the resistance when stoping handwheel 14 to remove mat 12 motions.Therefore, the enhancing body resistance device is with the method that overcomes the resistance that tensile bars 16 produced, and does gymnastics.

Mat 12 has great rigidity, and its two ends still can keep its long and narrow shape after being subjected to the load that tensile bars 16 applies.Be not only when handwheel moves in the exercise process, require mat can stand the resistance of tensile bars and hold its shape, and be when fitness equipment 10 is used for doing various gymnastics, require mat can stand standing of operator or other thrust.For example, be Fig. 3 C, 3H, during with various gymnastics shown in the 3J, operator's pin will be pushed down mat 12, and will be with handwheel towards drawing away from the direction of mat or pushing away.Certainly mat still can have a flexural deformation, as long as in the process that does gymnastics, it can hold out against, and each outward force that operator's continuous motion is brought is just passable.Preferably this mat can allow one of operator to ride in the above when the gymnastics of being shown in Fig. 3 J, still can keep enough rigidity.As various common used materials such as the foamed plastic of plastics, sclerosis, metal, timber, perhaps their combined material all can be used to make mat.

The enhancing body resistance device also is provided with a winding mechanism, is used for regulating the length and the dynamics of the tensile bars 16 that links with mat 12.On mat 12, can tensile bars 16 and mat 12 be linked with a plurality of winding parts or other element.A kind of winding mechanism of demonstration is seen Fig. 1, on the pair of sidewalls 18 of mat 12, a perforate 20 is arranged respectively.A perforate 24 is arranged on the rear wall 22 of mat 12 in addition.Tensile bars 16 is passed the perforate 20 on the sidewall 18, passes the perforate 24 on the rear wall 22 again, is twined parts 26 by one and fastens.It is a kind of winding parts of clamp class, and the

part

28 and 30 of a pair of intussusception engagement is arranged.Perforate 32 and 34 on

part

28 and 30 is aligned.Twining has the spring will be with part 28 bullets from part 30 in the parts 26.After tensile bars 16 was filled in the perforate 32 and 34 of aligned, spring forced part 28 to block tensile bars 16, thereby is fastened reliably.By these perforate push-and-pull tensile bars 16, can regulate its length, and by twining the position that parts 26 are guaranteed tensile bars 16.Regulate the length of tensile bars 16, that is regulate the resistance of its tension.

Except the exemplary winding parts 26 shown in Figure 1A, obviously as seen, equally also can use the winding parts of other similar types, as long as it can fasten two tensile bars reliably, but also enough big volume to be arranged, make it can not pass perforate 24.

Fig. 2 has shown another kind of available winding mechanism.Illustrate the bottom surface 36 of the mat 12 of another kind of fitness equipment 10 ' of the present invention.The winding parts 38 that a pair of protrusion is arranged on mat 12, each winding parts 38 is made of stem stem 40 and back-up ring 42, shown in Fig. 2 A.Tensile bars 16 all can be imbedded in the perforate 24, yet is wrapped on the stem stem 40 that twines parts 38 bottoms, reaches required length up to tensile bars 16.

Use with a kind of winding mechanism and connect though more than narrated two tensile bars, two kinds of different winding mechanisms of enhancing body resistance device use also capable of being combined connect two tensile bars.

Fig. 4 has shown the another embodiment of the winding mechanism that the present invention proposes.Consult Fig. 4, fitness equipment 10 " the bottom surface of mat 12 a pair of pulling force wheel 70 and a pair of rotating axle 72 are arranged.Each pulling force wheel 70 is to be contained on the axle 72 with a turn 74.Every tensile bars 16 and a pulling force wheel 70 link.Each pulling force wheel 70 has the space between 76, two back-up rings 76 of a pair of back-up ring will be enough to hold tensile bars 16, and the pulling force that makes tensile bars 16 can be wrapped between the back-up ring 76 is taken turns on 70.Tensile bars 16 on two pulling force wheel 70, each twines naturally in the other direction.Therefore, when tensile bars 16 when pulling force wheel 70 is pulled out, or be to be wrapped on the pulling force wheel 70, two pulling force wheels 70 all are to rotate with opposite direction mutually.Between two pulling force wheels 70 damping block 78 is set, the back-up ring 76 of its surface and pulling force wheel 70 meshes frictionally.There is a tension spring 82 to make damping block 78 keep meshing, stops the rotation of pulling force wheel 70 with the friction of pulling force wheel 70.Damping block 78 has a slide block 84, just is arranged in the sulculus 86 on the mat 12.Slide block 84 can slide in sulculus 86, makes damping block 78 and pulling force wheel 70 mesh or disengagement.Fig. 4 A has shown the upper surface of mat 12, and the slide block 84 of protrusion can slide in sulculus 86.(for example: the floor), the promotion slide block just can make damping block 78 and pulling force wheel 70 mesh or throw off the user as long as mat 12 is placed on a plane.Except shown in this figure, can stop outside the exemplary mechanisms that pulling force wheel 70 rotates, also available other device, as: ratchet and routine gear mechanism.

When using the winding mechanism of Fig. 4, preferably most of tensioning member 16 is wrapped in advance on each pulling force wheel 70.Slide block 84 is pushed away in sulculus 86 forward, and damping block 78 no longer meshes with pulling force wheel 70, and just can regulate the length of every tensile bars 16 this moment.Move back from separately pulling force wheel 70 and to pull out the tensile bars 16 that is wrapped in, just can make tensile bars 16 increase length.Equally, as shortening tensile bars 16,,, thereby make tensile bars 16 be wrapped on separately the wheel because turn 74 makes wheel turns as long as after damping block 78 is thrown off.The advantage of this winding mechanism is that the length and the tensile strength of every tensile bars 16 all can be regulated by each one.

Fig. 5 A～5D is the winding mechanism on the enhancing body resistance device, another available embodiment.Illustrate its structure and using method thereof in the mat bottom surface.From Fig. 5 A as seen, be provided with the winding parts 38 of a plurality of protrusions in the cavity of mat 12, the perforate that the inboard fixing tensile bars 16 in cavity two ends is passed mat 12 both sides separately links with handwheel, and the fitness equipment of this moment has been to use the tensile bars 16 of maximum length.This example is to be provided with five to twine parts 38, and the tensile bars 16 that may be adjusted to six kinds of different lengths is selected for use for the user.Fig. 5 D illustrates the winding method when having used shortest length tensile bars 16, and Fig. 5 B and Fig. 5 C illustrate the winding method of the third length and the 4th kind of length respectively, and surplus person can analogize.The characteristics of this winding mechanism are to use conveniently.

Available in addition scheme is that adjustable winding mechanism also can be contained on the handwheel, and tensile bars is adjusted to suitable length and dynamics.For example, tensioning member can be wrapped in the handle on the handwheel.

A pair of handwheel is arranged on the fitness equipment, and installing this has several benefits to handwheel.When doing exercises, they can separately move, shown in Fig. 3 B, 3D, 3M.Also but cocurrent and parallel moves apart mat, shown in Fig. 3 A, 3C, 3D, 3O, 3P.Also can singlely move, shown in Fig. 3 J, 3K.Thereby the user can isolate specific muscle groups and perform physical exercise, as those muscle groups on the half of body.

See Fig. 1 again, each handwheel 14 all has a handle 44 that is being supported by one wheel pairs 46.Handle should have the weight that sufficiently high rigidity can support operation person, and the most handy metal is made, and also available have enough other material of high rigidity and make, as plastics.The surface of handle will have concave and convex stripe, is beneficial to the operator and holds it with a firm grip.Wheel 46 also will have intensity and durable, can make with plastics, metal or other suitable material.The outer rim of wheel will be rolled at floor surface, should be more smooth, need to make with the material of can not scratch or damaging used surface.The rubber that can cover one deck band shape makes it have smooth, soft surface on this outer rim, can not damage the used surface of handwheel.The coupling each other of handle and wheel, allowing wheel is that rotate in the axle center with the handle.Habitual axle sleeve or bearing can be used for doing the coupling between handle and the wheel.When being easy to act as most handle and supporting operator's body weight, bearing still can make wheel smoothly rotate.Therefore, bearing arrangement can be used the ball class bearing.

In a word, handle and wheel must have enough rigidity, and are coupled together reliably with support operation person's body weight.To on equipment, can finish being used for several gymnastics of support operation person's body weight, shown in Fig. 3 A, 3B, 3O, 3P.

The formation of handwheel 14 has also comprised the method that tensile bars 16 and handwheel 14 are fastened.For example shown in Figure 1, handwheel contains a yoke cover 50, and it has a pair of tail end 52, and each tail end 52 all has a perforate 54 to be enclosed within on the handle 44.This coupling method makes that yoke cover 50 and handle 44 each other can be free movable.Therefore, when yoke cover 50 and tensile bars 16 were maintained fixed and connect, handle 44 still turned.Tensile bars 16 is connected to the central authorities of yoke cover 50.Space between two tail ends 52 of yoke cover 50 is enough wide, makes yoke cover 50 form a loop-drive, allows operator's hand can pass this loop-drive and catches handle 44, and can not be subjected to the interference of yoke cover.

As the method for yoke cover is set among Fig. 1, several advantages are arranged.At first, handle 44 can freely be rotated with respect to yoke cover 50.Thereby when the resistance that is provided by tensile bars 16 was determined the position of yoke cover 50, the operator can do and relate to the gymnastics that handle 44 rotates.Yoke cover 50 resistances that also tensile bars 16 provided are assigned on the handwheel 14 equably.Therefore, tensile bars 16 can not twisted, otherwise can be subjected to a torsion on the handwheel 14 in the motion process that does gymnastics.This yoke cover also makes the operator do to comprise that handwheel moves apart the various gymnastics of mat.For example, the operator can do the gymnastics that biceps curls, shown in Fig. 3 e.

A pair of tensile bars 16 links up mat 12 and handwheel 14 mutually, and it provides and has stoped handwheel 14 to move apart the resistance of mat 12.Tensile bars 16 is telescopic, and it is to make with conventional material retractable, that motion is produced resistance.Preferably make with the highly elastic material of strip or tubulose.Also can select a kind of circle formula spring for use, it to be enclosed in during use a flexibility, in the telescopic overcoat, prevent that the operator from being crushed by spring.

Two tensile bars 16 can be separated, and also can be coupled to each other.As shown in Figure 1, this is separated into two parts to the single high elastic rubber pipe of tensile bars 16 usefulness and uses.Tensile bars length is adjustable, makes fitness equipment can regulate to such an extent that can adapt to various different operating persons' needs, and can adapt to various gymnastics provides the needs of resistance in various degree to handwheel.Regulate many methods of tensile bars length, narrated hereinbefore.

The using method of enhancing body resistance device is that handwheel is moved back and forth towards the mat direction, and Fig. 3 A～3P has shown all gymnastics that can do.At first, the operator should regulate the length of tensile bars 16 before doing gymnastics, and makes it that desired degree is provided, the dynamics that stops handwheel to move.Then, the operator is placed on the desired position of operator with mat, in case mat slides.For example, the operator is placed on its knee on the mat, sees Fig. 3 A; It is ridden on mat, see Fig. 3 H, 3J; Or its buttocks is placed on the mat, see Fig. 3 N; Or the operator is seated mat is placed on its front, sees Fig. 3 C; Or directly press it to drive below the body mat, see Fig. 3 B.Then, the operator moves apart mat 12 with handwheel 14.Do gymnastics is exactly to require the operator to overcome the resistance that tensile bars 16 is produced.The operator both can follow handwheel 14 floor and roll, and saw Fig. 3 A～3D; When upright, the operator can push back handwheel 14 or draw from mat again, sees Fig. 3 E～3L.The operator can also back and forth push away mat 12 with handwheel 14 with pin, sees Fig. 3 M, 3N.In this way, the operator can temper many different muscle cohorts, comprises the muscle of arm, chest abdomen, trunk, back and shank.

The present invention has the fitness equipment of pulley to compare with other, has great advantage.The enhancing body resistance device can be used for doing many various gymnastics.The operator can through commonly used it do those conventional gymnastics and come degrease, see Fig. 3 E～3L; Also can do those requirements has the gymnastics of pulley to come body-building, sees Fig. 3 A～3D.The enhancing body resistance device is easy to regulate, make the operator can be not only fast but also easily change the size of resistance that tensile bars produces.The enhancing body resistance device also can make the operator perform physical exercise to some muscle cohort separately, for example, once uses a handwheel.

Though above by above-mentioned specific embodiment the present invention has been made description, be construed as the present invention and can also do further change, this patent is intended to contain various variations, purposes or the improvement of carrying out according to principle of the present invention.Also contained with disclosed known arrangement or enforcement convention and departed to some extent, but still be subordinated to the scope of the technology of the present invention and application principle thereof.This patent has also been contained the scope of claims of the present invention.
