Abstract

The invention relates to a training device comprising two handles (2), between which a flywheel (6) is suspended on a rope (4). By twisting the rope and repeatedly pulling on the handles (2), the flywheel (6) is caused to rotate about the axis of rotation (10) thereof. The rope (4) is passed through two passages (8) through the flywheel (6). The passages (8) run obliquely with respect to the axis of rotation (10). The friction between the rope and a wall of the passages when the training device is in use is thereby increased and the flywheel (6) is prevented from sliding down the rope (4) when the training device is being used vertically.

Description

Trainer

Background technology

The present invention relates to a kind of trainer, this trainer has two grip element, and arranging betwixt has a rotary body, and said rotary body has two passages, can guide a rope that is connected with these grip element through said passage.Reverse said rope and can make said rotary body through repeatedly spurring rope around the rotation of its rotation.

The for example explanation in WO 2005/046805 of a kind of like this trainer.

Said rotary body constitutes flywheel usually, and its weight for example is about 100 grams.Through pulling times without number on grip, said flywheel is once all quickened in every pulling in the opposite direction.Owing to effect of inertia, produced the enough big power of the exercise purpose that can be used in selected muscle region thus.

The salient point of this trainer is that its simple formation also is application possibility very flexibly simultaneously with its compactedness.This trainer especially can also be used to mould selected muscle parts on therapeutic purposes.

At this, said trainer not only can be operated (promptly when rope in fact flatly extends) in the horizontal direction, and can handle on other direction in spaces arbitrarily, promptly for example operates obliquely or vertically.Yet said rotary body but can appear because its deadweight and problem on the grip element below sliding into along rope downwards under the situation about being vertically oriented.They are installed in the shoe on the rope or are installed in knot in the rope in addition and not too be applicable to and remedy this problem, because for example can produce interference when the routine replacement rope.

Summary of the invention

The present invention based on purpose be to prevent when vertically using under a kind of like this situation of trainer that said rotary body is to lower slider and guarantee high as far as possible comfort simultaneously.

According to the present invention, the trainer of the characteristic of this purpose through having claim 1 is realized.In this trainer, provide, passing these passages said rotary body, that said rope is directed passing therein is not as common, to be parallel to rotation, extends but favour said rotation.Therefore these passages have ground, an angle of inclination to pass usually (massiven) rotary body discoidal, especially entity from a side to relative side extension to said rotation.Therefore this passage also extends to a plane vertical with rotation simultaneously obliquely.

Consider that at this this embodiment the guiding function of passing the inclination of said rotary body has increased the friction between the wainscot wall area territory of said rope and passage, said rotary body to lower slider when having avoided vertical training position so at least to a large extent.A special advantage at the passage of this this tilted alignment is, even when for example changing rope, also can guide rope to pass without a doubt simply.So that rope is removed and to be reversed (Entdrillen) or when reversing, higher friction just appears under training condition preferably when the pulling rope during very little tensile load.Pass through the pulling force that applied because the uneven orientation of said access portal, when carrying out training and operation with the rope compressing on a wall zone.

Preferably, said rotary body constitutes the entity flywheel that solid material (Vollmaterial) is made, and especially typically weight is about 100 grams, for example in the scope of from 100 to 300 grams, preferably in the scope of about 175 grams.Said rotary body can be used metal, plastics or preferably constitute with hard rubber.The diameter of wheel is in typical several centimetres scope, for example in the scope between from 5 to 10cm, preferably in the scope of about 7.5cm.The thickness of flywheel is for example at several centimetres, especially about 2.5cm.

According to a useful embodiment, these passages extend to said rotation on its total length obliquely.This allows to introduce simply these passages, the through hole that for example is provided with obliquely through a said relatively rotation.Preferably, also extend through said rotary body point-blank at these these passages.

According to of the present invention one preferred embodiment, these passages cross one another in said rotary body.Substituting ground also might make these passages cross the middle part of said rotary body, does not but intersect each other.Preferably complementally propose, these subregions said rope, that be directed passing said rotary body cross one another similarly.Guarantee through this measure, even can prevent also that under minimum tensile load said rotary body is along said rope slip.Through the subregion that crosses one another of said rope, said rotary body just nearly all is supported in the spandrel zone (Zwickelbereich) that is made up of the said subregion that crosses one another.This embodiment can with simple mode through two as access portal and through hole intersected with each other and that run through is realized, these through holes are at the middle part, just cross one another in the inside that half the height is in said rotary body.These subregions of said rope are passed through and are contacted with each other in this crosspoint by each other in said crosspoint.

According to an effectively expansion proposition, under the situation of these passages that cross one another, these passage relative rotation axi lines are orientated with an angle of inclination, and preferably, this angle of inclination is between 15 degree and 60 degree.Especially in the scope of this angle of inclination between 30 degree and 50 degree.According to one preferred embodiment, this angle of inclination be about 45 the degree, thereby the angle between said two subregions of said rope be 90 the degree.Test shows, can prevent sliding stop especially effectively with such angle.

The replacement scheme of the passage that extends as orthoscopic penetratingly proposes according to a useful embodiment, and these passages have two at least to the part parts of said rotation with the different angles orientation.What this preferably proposed be; Each extends said two part parts and roughly meets at said rotary body middle part since orthoscopic ground on the direction that is tilting to said rotation, the said rotary body outside, thus make these part parts at said middle part with V font roughly, under a stable condition, constitute with a zone with rounding.

Said part part is also nonessential to be straight line.Substituting ground might these subregions be that crooked perhaps these passages constitute on the whole agley also.Said two passages are preferably correspondingly crooked to said rotation convex ground.Said in theory subregion also can deviate from said rotation to be pointed to, and for example spill ground is crooked perhaps angulately.

In order can simply rope to be introduced and to pass these passages and guarantee simultaneously higher friction be just arranged under very little tensile load, these passages have a diameter between 1.3 times to 3 times of rope diameter effectively.

High load capacity on rope, occurs because rope is reversed and remove when reversing in the zone that gets into these passages, so propose effectively, said passage just has the introducing gradient respectively at the entrance side and the outlet side of passage distolateral.At this effectively, these introducing gradients constitute to said rotation asymmetricly.

The specific embodiment

Trainer according to Fig. 1 has two grip element that constitute the belt collar 2, and stationary rope 4 on said grip element, and said rope passes a rotary body that constitutes flywheel 6 in two passages 8.Flywheel 6 through by solid material for example the entity of metal, hard rubber manufacturing constitute, this entity is only run through by these passages 8 that preferably constitute through hole.The belt collar 2 for example with a kind of textile material, with plastics or can also use other elastomeric material such as rubber manufacturing.As to the substituting of the belt collar 2, other grip element can also be set, for example ring, bar or the like.Yet the advantage that the belt collar 2 provides is; It provides high grasping comfortableness and especially all right expanding application scope; Its mode is for example: the belt collar 2 not only can be used grasped, but for example can also be placed on other the body part, for example on the pin or on the head.

The working method of said trainer is following:

At first come to reverse a little rope 4 through manual rotary flyweights 6.Then remove and reverse and make flywheel 6 around its rotation 10 rotations through spurring rope after the said belt collar 2 will reverse.So the rotation of flywheel 6 causes reversing in the opposite direction, this removes again and reverses through the pulling belt collar 2 again, or the like.Rotary speed according to being produced very high power and the moment of inertia possibly occur at this.

Can train different muscle regions with simple mode effectively with this simple trainer.Said trainer can worked on the orientation arbitrarily.Partly can also vertically or on the direction that tilts work.The problem that in such working method, exists is, flywheel 6 towards below the direction of the belt collar 2 on slide and no longer be arranged in the middle part.

For fear of this situation, what proposed is, arranges a plurality of passages 8 in the both sides of rotation 10, and these access needle are passed flywheel 6 obliquely to rotation 10 and extended.

According to first embodiment shown in Figure 2, these passages 8 pass the through hole of whole flywheel 6 with constituting orthoscopic, and these through holes cross one another at the middle part of flywheel 6, just on half height, cross one another.At this, the crosspoint is on rotation 10.

Guide a subregion 4A, the 4B of rope 4 respectively by these two passages 8.Equally also cross one another at this this two

subregion

4A, 4B, just equally also pass to orthoscopic flywheel 6.These two

subregion

4A, 4B are adjacent to each other on the crosspoint.

As can finely finding out in the cross-sectional view of Fig. 2, these two

subregion

4A, 4B constitute a kind of bag-like region territory or spandrel zone, and this zone is filled by the middleware 12 of central authorities of flywheel 6.These two

subregion

4A, 4B almost hold and engage this middleware 12.

These passages 8 have one to introduce the gradient 14 respectively at its entrance and exit place.These introducing gradients constitute in this embodiment asymmetricly and especially only are provided with to middleware 12.With only schematically expression different be that middleware 12 is whole in the zone of introducing the gradient to be that rounding ground constitutes, as much as possible little to the load of rope 4 with maintenance.

In order can easily to introduce rope 4 and to guarantee sufficiently high friction simultaneously, the diameter of passage 8 just its internal diameter (lichte Weite) is about 1.3 times to 2 times of rope diameter.For example the diameter of rope is 3mm and the diameter of passage 8 is about 5mm.

These passage 8 relative rotation axi lines 10 are arranged with an angle of inclination a obliquely.Said in this embodiment angle of inclination is about 45 degree.

In the vertical view of the flywheel with circular cross section 6, can find out the inlet of these passages 8 and the asymmetric embodiment of introducing the gradient 14, the said introducing gradient is only constituting on the side of rotation 10 orientations.Spacing between these two passages 8 is typically in 1 to 3cm scope.

In alternate embodiment shown in Figure 4, each is made up of corresponding passage 8 two

part part

8A, 8B, and two part parts are mutual is orientated angledly for this.These passages that constitute 8, directed toward each other tips make these passages 8 not cross one another apart from one another by opening angledly like this.With shown in the top of the horn end different be that they are preferably implemented on rounding ground, so that rope is not constituted (scharkantigen) turning point with sharp edges.

Last according to the configuration that a kind of continuous bend of these passages 8 is provided in the enforcement variant shown in Figure 5.Radius of curvature is constant in this embodiment.

With shown in implement variant different be that the subregion and the sort of combination that is parallel to the subregion of rotation 10 of crooked subregion and orthoscopic extension can also be arranged.
