Abstract

The exercise device comprises two handles (1), which are enclosed with the right hand and left hand. Each handle has a rope drum (5), whose drum axle (15) is placed inside the enclosing hand and is aligned perpendicular to the inner surface of the hand. A rope (11) is wound on the rope drum, where a rope end is led out from the handle and is firmly connected mechanically with a predetermined position on the body, particularly torso, such that the winding of the rope by surmounting the initial load is required for the movement of the arm.

Description

The invention relates to a trimming device, which is designed to support the structure of the musculature of the human body, in particular the musculature of both shoulder areas and the areas of both arms - including the hands.

Trimming machines for exercising the musculature of the human body are known and used in various designs, including trim devices that can be used during jogging or walking or even when sitting or standing by persons, to the muscles of the upper body, in particular the shoulder area including the arms, to train.

A in this regard from the US 4,441,707 known isometric training belt is equipped with a hip belt, which serves as a guide for a non-stretchable, circulating around the user's waist rope. At the two ends of the rope is ever a handle for the hands of the user. The rope ends are alternately moved back and forth in response to swinging hand or arm movements, while the middle part of the rope is easily guided by the training belt around the hips. The resulting isometric muscle contractions cause voltage changes in the muscles involved, but no change in length, since the arm movements require little or no effort; the device is therefore only the extension of the exercise spectrum in a strength training.

Another trimmer is in the US 1,432,013 described. In this case, stretchable cables are fastened with one end to a hip belt, while at the other end handles for the user are arranged. Depending on mutually right and left forward hand or arm movements, the distances between the respective handle and the cable attachment to the girdle be increased, the cables must be stretched under force. Muscle development is promoted due to this effort.

A disadvantage of the latter device is that the stretchy ropes are naturally subject to wear, which has decreasing, ie non-uniform expansion forces result. In addition, the ropes have a certain length and are designed for certain tensile forces, making them suitable only for users who have a matching arm length or a training condition corresponding to the tensile forces. Such a trimming device can only be used to a limited extent for several users with different training conditions and different stamina.

A trimmer of other construction is from the US 5,618,249 A known. This consists of a hip belt on which a cable drum is provided in the back region for each arm or body side. Handles are attached to the cable ends leading out of the rope drums. In order for the cables to run from the user's body to his or her hands in certain directions, guide rods with guide rollers for the cables are also present in the back region of the hip belt. The preparation of such a trimmer is material and cost intensive, its handling is adversely affected due to the relatively large spatial structure and its weight.

Also in this device, depending on mutual hand or arm movements that increase the distance between the girdle and the handles, ropes unwound under the power of cable drums. In order for the muscles to exert tensile forces during unwinding, friction disks are provided in both cable drums, which complicate the cable extension. The friction is adjustable, so that too overcoming tensile forces are variable depending on the respective set friction. At the same time restoring forces are generated when removing the ropes, which provide each for the rewinding on the cable drums, as soon as the distance between the girdle and the handle in question is reduced. The winding is not slowed down by the friction discs.

Another trimmer is out of the US Pat. No. 6,309,328 B1 known. In this trimmer are within a housing which is provided on its outer side with a handle, a cable drum with a wound under tension rope and a device which complicates the unwinding of the rope by acting on the rope frictional force. A led out of the housing end of the rope can be attached to an object that rests relative to the trimmer, so that due to back and forth swinging hand or arm movements, the distance between the trimmer and object can be changed. When increasing distances in each case the braking force is to be overcome, and it is also a restoring force generated, which causes the subsequent reeling of the rope rewinding the cable drum. The winding is not slowed down by the friction device.

In both latter trim devices for generating and adjusting the pull-rope forces on the one hand and for generating the Restoring forces on the other hand separate devices present, which is disadvantageous due to the relatively large space structure and weight in terms of handling by the user.

Based on this prior art, the present invention seeks to provide a trimming device, which is used by both persons of different constitution and different condition as well as the disadvantages of the prior art in terms of handling by the user no longer has. Incidentally, in this trimming device, the leverage applied to the wrist should be further reduced.

According to a trimming device of the type mentioned above is equipped with two handles, one of which is designed to grip around with the right hand, the other for gripping with his left hand. In this case, each handle on a cable drum, the drum axis is - when using the trimming device - both within the encompassing hand and is aligned substantially perpendicular to the palm of the hand.

Furthermore, a cable is wound under pretension on each cable drum, led out of which a rope end of the handle and - when using the trimming device - with a predetermined position on the body of a user, preferably on Hull, mechanically firmly connected. Arm movements, which increase the distances between the handles and the attachment positions on the body, unwind the ropes by overcoming the bias, thereby requiring manual exercise supports the muscle structure.

This training can be performed when the occupant is at rest relative to their environment, for example, standing, but also on the move, such as jogging. The use can be done for sports training, but also in connection with rehabilitation and physiotherapy.

The trim device according to the invention is characterized inter alia by the fact that the axis of the respective cable drum is within the encompassing hand, wherein they are each aligned perpendicular to the palm, and the ropes immediately below the hand, namely below the edge of the hand, emerge from the handles and in the direction of the user's body. This provides a significant ergonomic advantage over the prior art since the distance between the exit position of the cable from the respective handle and wrist is minimized and thus minimizes the adverse leverage exerted by the pull-out force on the wrist is.

In a first preferred embodiment of the invention, the generation of the bias under which the ropes are wound on the cable drums is provided by means of spiral springs, which are also arranged inside the handles. The coil springs produce when unwinding the cables restoring forces, on the one hand correspond to the manually to be overcome pull-out forces, on the other hand cause the rope is rewound on the cable drum when reducing the distance between the respective handle and the attachment position of the rope on the body. The coil springs are functionally assigned to the cable drums so that their spring force counteracts the unwinding of the rope from the cable drum.

In a further preferred embodiment of the trimming device according to the invention means for varying the bias are provided under which the ropes are wound on the cable drums. These are, for example, designed as changing devices for the exchange of coil springs with different spring constants against each other. Alternatively or in addition thereto, adjusting devices may be provided which are designed to increase or decrease the preload. This can be done in a conventional manner with adjusting wheels on the handles, with which the bias of the coil spring is either continuously or progressively variable.

With a suitable choice of the coil springs, the spring force can be specified such that it is constant. This means that the force with which the rope is unwound from the rope drum is independent of the unwound rope length. Alternatively, however, the spring force can also be linearly increasing, so that the longer the unwound rope, the spring force and, accordingly, the extraction force necessary for unwinding increases all the more.

To achieve a constant spring force, the rope is wound on a conical drum. This cable drum preferably has rope grooves.

The outer shapes of the two handles are designed unequal in that one handgrip is ergonomically adapted to the left hand, the other handgrip is ergonomically adapted to the right hand. The relevant features by which both handles differ are mirror images. Such are, for example
the outlet openings for the ropes on the handles designed so that the rope exit direction is inclined in each case to the body.

In a particularly preferred embodiment, a plurality of different attachment positions on the trunk of the body are provided for the outgoing from the handles cable ends and provided for selection. This makes it possible to additionally vary the extension directions of the ropes from the handles. Are defined the attachment positions, for example, by means of a belt to be attached to the torso, preferably at the hip, or a belt system to be placed around the upper body. Belt or belt system have at the attachment positions coupling elements for the cable ends, while at the cable ends to corresponding coupling elements are provided, which allow easy to manufacture and also to be loosened connection and may be formed, for example in the form of a bayonet lock or a hook-eye connection ,

Optionally, the coupling of the trimming device according to the invention is provided with means for measuring characteristics that characterize the training state of the body or the musculature, such as Seilauszugskraft- and exercise time measurement and their link to determine the energy consumption, pulse rate measurement and / or measurement of body temperature. Thus, a monitoring and optimization of training can be made. In this context, devices for the visually perceptible display and / or for storing the determined results may also be present.

In a further advantageous embodiment, the handles of the trimming device according to the invention are provided with brackets to protect the back of the hand against impact injuries. Optionally, at least one of the handles with a light source can continue be equipped, preferably in the dark to emit a light signal and thus in the open to prevent collisions with oncoming persons.

In a further advantageous embodiment, the distance between the exit position of the rope from the handle on the one hand and the pivot point within the wrist area on the other hand further reduced in a trimming device of the type mentioned that the cable outlet opening is no longer below the edge of the hand and not in a straight line Extension of the direction is arranged, in which the cable is unwound from the cable drum or wound up as a result of a restoring force on the cable drum, but the cable outlet opening is positioned laterally offset to this direction.

The distance between the exit position of the rope from the handle and the wrist area could be further reduced and thus the disadvantage of the pull-out force on the wrist leverage effect can be further reduced.

The lateral offset is achieved by deflection of the cable guide direction by means of rollers or sliders.

The reference numerals drawn in the figures have the same meaning each, even if they are not explicitly mentioned in the description of the embodiments for each figure.

In Fig. 1 a handle 1 of the trimming device according to the invention is shown. Fig. 1a shows a lateral interior view in a section through the in Fig. 1 b specified level AA. Fig. 1 b shows the front view overlooking the narrow side of the same handle. 1

How out Fig. 1a can be seen, the handle 1 by way of example of an upper housing part 2 and a lower housing part 3. Both housing parts 2, 3 enclose a cavity 4, in which a cable drum 5 is arranged. The outer contour is adapted from an ergonomic aspect of a gripping hand, wherein during use on the outer surface 6 of the handle 1 of the palm rests, while the outer surfaces 7 and 8 are enclosed with four fingers of the hand and the thumb can rest on the outer surface 9 or laterally on the outer surface 10 (see also FIG Fig. 1 b) ,

In Fig. 1 a and Fig. 1 b are arranged on the outer surface 6 arranged strip-shaped knobs 16, which give the surrounding fingers additional support.

On the cable drum 5, a cable 11 is wound under spring tension, which is led out through an opening in the upper housing part 2 from the handle 1 at one end, on which is provided with a coupling element 12 handle. To prepare for the use of the trimmer, the end of the rope on the handle 13 is manually pulled out of the handpiece 1 and fastened by means of the coupling element 13 on a belt 14 at the waist of the user (see. Fig. 2 ).

Fig. 2 shows an example of such arranged on the body of the user belt 14, which has only one attachment position 18 for the coupling element 12 and the handle 13 in this case. The attachment position 18 on the belt 14 determines the direction of the drawn-out rope 11 from the handle 1 to the body. This direction is defined by means of a coupling element which is formed corresponding to the coupling element 12 on the handle 13 and receives this. The

Connection of both coupling elements together is designed for example as a bayonet lock.

In further, likewise within the scope of the invention embodiments of the belt 14 may be provided with a plurality of such mounting positions 18, so that with the choice of different mounting positions 18, the cable extension direction can be varied. Included in the concept of the invention is the training and use of a wear on the upper body belt system instead of in Fig. 2 illustrated hip belt to increase the range of variation in selectable directions of extension. The number and arrangement of the attachment positions 18 are preferably carried out symmetrically to the body center and thereby assigned to the left hand and the right hand.

The handle 1 according to the invention is designed so that the cable drum 5 including its axis 15 is within the hand, which encloses the handle 1, which advantageously has the consequence that the rope 11 below the hand, namely directly on the hand edge, from the Handle 1 exits and runs in the direction of the body of the user.

With this technical solution deviating significantly from the prior art, it has been possible to achieve the distance a between the To reduce exit position of the cable 11 from the handle 1 and the wrist area to a minimum, and thus to minimize the force exerted by the pull forces on the wrist leverage, as is apparent from the Fig. 3 is apparent.

In Fig. 4a is already based Fig. 1 and Fig. 3 explained handle 1 shown again, and although uncut with a view towards the outer surface 8 (see. Fig. 1 ), here the handle 1 for the left hand.

Fig. 4b shows the same handle 1 in a section through the in Fig. 4a specified level BB. Illustrated here are exemplary embodiments of the cable drum 5 and a spring housing 20 in which a mechanically connected to the cable drum 5 coil spring is housed, which provides the pull-out force, which is applied manually to unwind the cable end of the cable drum 5. At the same time, the spiral spring generates the rewinding force, which rewinds the cable 11 onto the cable drum 5 as soon as the pull-out force decreases or becomes smaller than the restoring force. This is done in response to the arm movements which increase or decrease the distance between the handle 1 and the attachment positions 18 on the user's body. The thereby executed by the cable drum 5 rotational movements "R" are in the FIGS. 1 a and 3 shown.

Fig. 5 shows a perspective view of a handle 1, which is provided on its underside with a label "L", which assigns the handle 1 of the left hand. This marking is particularly helpful for the embodiments in which the two belonging to the trimming device handles 1 in details mirror images differ and thus the left or right hand are assigned. Thus, for example, the exit direction of the cable 11 is inclined out of the handle 1 to the body of the user, which reversed applies also to the handle 1, which is provided for the right hand.

In Fig. 6a a handle 1 of the trimming device according to the invention is shown according to a second embodiment in a lateral interior view. Fig. 6b shows the top view of the same handle 1 in a section through the in Fig. 6b specified level CC.

How out Fig. 6a can be seen, the handle 1 consists of an upper housing part 2 and a lower housing part 3. Both housing parts 2, 3 enclose a cavity 4, in which a cable drum 5 is arranged. The outer contour of the handle 1 is ergonomically adapted to a gripping hand, wherein the outer surface 6 of the palm lies against the outer surfaces 7 and 8 are enclosed with four fingers of the hand and the thumb on the outer surface 9 or laterally on the outer surface 10 (FIG. see. Fig. 6b ) can rest.

The cable drum 5 is thereby including its drum axis 15 within the handle 1 enclosing the palm.

On the cable drum 5, a cable 11 is wound under spring tension, one end of which is attached to the circumference of the cable drum 5, while the other end is led out through an introduced into the housing part 2 cable outlet opening 22 from the handle 1 (see. Fig. 6b ). At the lead out end of the rope is as out Figure 6b If the trimmer is to be used, the end of the rope is pulled out manually by means of the grip 13 from the handpiece 1 and by a coupling element 12 (see. Fig. 8a ) is fastened to a position resting relative to the handpiece 1, which position is for example at the hip of the user.

Out Fig. 6b exemplary embodiments of the cable drum 5 and a spring housing 20 can be seen. In the spring housing 20 is a mechanically connected to the cable drum 5 coil spring is housed, which provides the pull-out force, which is applied manually to unwind the cable end of the cable drum 5. At the same time, the spiral spring generates the rewinding force, which rewinds the cable 11 onto the cable drum 5 as soon as the pull-out force decreases or becomes smaller than the restoring force. This happens in response to the arm movements, which increase or decrease the distance between the handle 1 and the position at which the handle 13 is attached.

The in Fig. 7 belt 14 shown by way of example and arranged on the hip of the user has such a fastening position 18 for the grip 13. The attachment of the handle 13 to the belt 14 can be done for example by means of a known bayonet closure, wherein the coupling element 12 forms an element of the bayonet closure.

The attachment position 18 on the belt 14 determines the direction of the drawn-out rope 11 from the handle 1 to the user's body. In order to make this direction ergonomically optimal, the invention provides that the rope 11 centrally "M" in height of the handball of the hand exits the handle 1, which surrounds the handle 1, wherein the distance a between the exit position of the cable 11 from the Handle 1 on the one hand and the pivot point 23 within the wrist area 17 on the other hand (see. Fig. 6a ) is reduced to a minimum level and thereby also the force exerted by the pull-out force on the wrist leverage is reduced to a minimum.

Furthermore, here is essential to the invention that the cable outlet opening 22 on the handle 1 is not in rectilinear Extension of the direction is arranged, in which the cable 11 is unwound against bias of the cable drum 5 or wound up as a result of a restoring force on the cable drum 5, but is laterally offset to it, as in Figure 6b can be seen. With this lateral offset at the same time the possibility of contact between the rope 11 and the palm is reduced during use.

The lateral offset is achieved by deflecting or changing the cable guide direction. How out Fig. 6b shows, the deflection by means of roller 24 or by means of slider 25 is made, both variants are shown here with respect to their positioning here only by way of example. Thus, the deflection is exclusively by means of rollers 24 or the deflection exclusively by means of sliders 25 as well within the scope of the invention as their example in Fig. 6b shown combined application. The slightly increased friction in the choice of sliders 25 in comparison to the deflection by means of rollers 24 is not disadvantageous because the trimming device is intended in any case intended for manual overcoming the pull-out force. The term slider 25 in the context of the invention is to be understood as meaning both a curved portion of the inner wall of the housing part 2 for this purpose, and a component with a curved contour which is manufactured separately and placed on the inner wall.

The direction of the lateral offset relative to the rectilinear extension of the unwinding and winding direction of the cable 11 from or to the cable drum 5 is defined as being in Fig. 6a perpendicular to the drawing plane and in Fig. 6b lies in the drawing plane.

Compared to previously known trim devices of this type, it has been possible with the invention to reduce the distance a between the exit position of the cable 11 from the handle 1 and the pivot point 23 of the wrist to a minimum and thus exerted by the pull-out force on the wrist leverage to minimize.

Fig. 8 shows the already based Fig. 6 explained handle 1 in exterior views, wherein Fig. 8a represents the handle 1 with a view of the outer surface 8, while Fig. 8b the side view, namely the view of the outer surface 6 shows. How out Fig. 8a and Fig. 8b can be seen, on the outer surfaces 6 and 7 strip-shaped knobs 16 are provided, which give the enclosing hand additional support.

As from the synopsis of Fig. 6b . Fig. 8a and Fig. 8b Furthermore, the cable 11 is passed for the purpose of lateral offset by a protuberance 26, which is worked on the outer surface 8. It is expressly on it that the representation is not to scale, that is, both the amount of lateral offset and the dimension of the protuberance 26 are appropriate to the physical conditions of the user, such as children or adult male or female persons.

In further, likewise within the scope of the invention embodiments of the belt 14 may be provided with a plurality of fastening positions 18, so that with the choice of different mounting positions 18, the cable extension direction is variable. Included in the concept of the invention is the training and use of a wear on the upper body belt system instead of in Fig. 7 shown hip belt to increase the range of different selectable cable pullout directions. The number and arrangement of the attachment positions 18 are preferably carried out symmetrically to the center of the body and thereby assigned to the left hand or the right hand or body side.

Fig. 9 shows a self-explanatory plan view of both handles of the trimming device according to the invention with markings 21 for the purpose of defined assignment to the left and right hand or body side of a user.

All mentioned in the foregoing description as well as the removable only from the drawings features are further components of the invention, even if they are not particularly highlighted and / or mentioned in the claims.

The invention is not limited to the embodiment, but in the context of the disclosure often variable. Thus, in a further preferred embodiment and use of the trimming device according to the invention, the left hand grip 1 and. the right hand grip 1 is arranged in each case on a glove 27, preferably integrated into the glove 27. This further embodiment of the invention is in FIG. 10 shown schematically, here by way of example a left glove.

In another, further preferred embodiment of the trim device according to the invention, the handle, the left handle or the right handle, respectively combined with a sports floor. For example, the sports floor can be a Nordic Walking floor, a fitness floor, an inline skating floor, a ski pole or another floor designed for sports purposes. Schematically, such an embodiment and use of the invention in variants in the FIGS. 11 to 13 shown.

In this variant of the invention and its use, the rope is not led out of the handle below the edge of the hand but directly above the hand of the user, who grasps the holding section 30.

In a further embodiment according to FIG. 12 the rope within the handle 29, in particular of the holding portion 30 is guided to the lower end portion of the handle 29 and deflected there, so that the rope 11 is also led out here below the hand edge of the user. In another, further embodiment, the in FIG. 13 is shown, the respective handle according to the invention is not arranged on or in the handle 29 of the sports stock 28, but provided directly below the handle 29 on the shaft 33 of the sports stock 28. In this embodiment, the handle according to the invention is arranged in a special housing 32, which at the same time has a fastening unit with which this special handle with its housing 32 on the shaft 33 can be fixed. Preferably, the attachment unit is such that the special Handle is optionally solvable. In this new handle, the rope 11 is led out in the upper region of the housing 32, so that it also moves immediately below the user's hand edge, so that the distance a to the pivot point 23 is minimal.
