Abstract

Training device with an elastic drawstring (30; 30 ') which is anchored to a frame (10; 10a, 10b) and on which a handle (32) for stretching the drawstring is arranged, characterized in that the drawstring (30; 30 ') is guided in meandering fashion in several mutually parallel strands from the handle (32) to the anchoring point via deflection rollers (20, 22) held on the frame.

Description

The invention relates to a training device with an elastic drawstring, which is anchored to a frame and to which a handle for stretching the tension band is arranged.

Out DE 20 2011 101 454 U1 is a training device of this kind is known, which can be used as a sports device as well as for physiotherapeutic purposes. The training effect results from the fact that the user has to overcome a force when stretching the drawstring, which increases progressively with increasing extension length of the drawstring.

There are also training devices are known in which a weight is suspended on a mostly guided by a pulley, non-elastic drawstring, so that the user lifts the weight when pulling the drawstring. In these devices, the force to be overcome is not progressive, but essentially independent of the extension length.

The object of the invention is to provide a compact training device in which the force curve can be better adjusted.

This object is achieved in that the drawstring is guided over the frame held pulleys meandering in several mutually substantially parallel strands of the handle to the anchor point.

Due to the meandering course of the drawstring is achieved that the total length of this drawstring can be a multiple of the dimensions of the frame. Since the deflection of the drawstring is done via rollers, it is still possible to stretch the drawstring uniformly over its entire length. The force that the user must overcome when pulling the drawstring is proportional to the ratio between the draw length and the total length of the drawstring in the relaxed state for a drawstring of given modulus of elasticity. If the drawstring is biased so that it already has some tension in the rest position of the handle, the force is also proportional to the bias. Due to the large in relation to the size of the frame overall length of the drawstring, the invention allows to set a force curve in which the force is indeed dependent on the extension length, but with less progression than conventional training devices with elastic drawstring. In this way can be achieved with a relatively compact device training effects that are not achievable with conventional devices so.

Advantageous embodiments of the invention are specified in the dependent claims.

In the following embodiments are explained in detail with reference to the drawing.

Show it:

1 a view of a training device according to a first embodiment of the invention;

2 a view of the training device after 1 in another setting position;

3 and 4 Training devices according to modified embodiments; and

5 a therapeutic training device on a hospital bed.

This in 1 shown exercise device has a rigid frame 10 with two parallel bars 12 . 14 on which in the example shown are vertical and at both ends by trusses 16 . 18 connected to each other.

At the opposite ends of the pole 12 are pulleys 20 rotatably mounted. Further pulleys 22 with slightly smaller diameter are evenly spaced on the trusses 16 and 18 stored.

A sleeve 24 is low-friction on the pole 12 slidable and help of a locking button 26 can be fixed in the desired height. On the sleeve 24 is another pulley 28 arranged.

An elastic drawstring 30 A handle on one end 32 is guided over the pulleys as follows: From the handle 32 runs the drawstring 30 over the pulley 28 on the sleeve 24 first to the upper pulley 20 At the rod 12 , From there, the drawstring runs down to the first pulley 22 at the lower crossbar 18 , then to the second of the pulleys 22 on the upper crossbar 16 and on to the third deflection roller 22 at the lower crossbar 18 , From there, the drawstring extends up to the fourth (last) pulley 22 on the upper crossbar 16 , Here the drawstring is moving back towards the front (ie, on the side of the handle 32 located) bar 12 diverted. About a "loose" role 34 the drawstring then runs to the third deflection roller 22 on the upper crossbar 16 where there is the second pulley 22 at the lower crossbar 18 is diverted. From there, the drawstring runs to the first deflection roller 22 on the upper crossbar 16 and on to the lower pulley 20 and finally back to the sleeve 24 to which the end of the drawstring is attached.

At the loose roll 34 is a tension rope 36 attached, that over the fourth pulley 22 at the lower crossbar 18 to a self-locking clamping fitting 40 At the rod 14 running. At this clamp fitting 40 is the tension cable 36 tensile strength held.

When a user grips the handle 32 captured and the elastic drawstring 30 can take off, the role 34 do not give in. Rather, this role works 34 as anchoring point, which is an elastic extension of the tension band 30 forces. The rotatability of the pulleys 20 . 22 and 28 however, ensures that the stretching of the drawstring 30 distributed evenly over its entire length. When the handle 32 is pulled to a certain extension length, so corresponds to the circumferential movement of the guide roller 28 the full extension length of the handle. The circumferential movement of the upper pulley 20 is somewhat smaller, because the drawstring 30 also on the strand between the pulleys 28 and 20 already stretching something. The same applies to the subsequent pulleys 22 , The smallest circumferential movement guides the deflection roller 20 at the bottom of the pole 12 out. The rotation of this roller corresponds to the elongation of the strand of the tension band, that of this lower pulley 20 back to the sleeve 24 runs.

The relatively large total length of the meandering guided tension band 30 allows the drawstring to the handle 32 extend relatively far, for example, a complete arm length or leg length of the user without the elastic restoring force of the drawstring has too strong a progression or even the yield strength of the drawstring is reached.

With the help of the role 34 and the tensioning cable 36 can the bias of the tension band 30 be set. If the preload is to be increased, simply pull on the free end of the tensioning cable 36 so that's the role 34 moved down and accordingly the tension of the drawstring 30 is increased. The tensioning rope 36 is due to the clamp fitting 40 automatically fixed in the new position.

On the drawstring 30 is near the handle 32 an attack 42 attached to the bearing block for the pulley 28 strikes and thus prevents the handle 32 due to the bias of the drawstring all the way to the pulley 28 is used.

If the pretension of the drawstring is to be reduced, then the tensioning cable becomes 36 just with a slight jerk from the clamp fitting 40 solved, so that the tensioned drawstring the role 34 Pull up until the tensioning cable in the desired position again on the clamping fitting 40 is fixed.

The height of the handle 32 can be adapted to the respective body size of the user. This is the locking button 26 the sleeve 24 Loosened, so that the sleeve along the rod 12 can be moved to the desired position. As both ends of the drawstring 30 are fixed to this sleeve, the total length of the tension band does not change, but the tension band moves only slightly on its meandering path over the pulleys.

2 shows the exerciser in a state in which the sleeve 24 and the handle 32 located at a slightly lower altitude. In addition, here is the role 34 in a slightly lower position, so that the tension band is more taut.

3 shows a training device according to a modified embodiment, with a drawstring 30 ' in the form of an endless belt. The sleeve 24 here has two pulleys 28 on, and on the handle 32 is another pulley 44 attached to the the endless drawstring 30 ' is diverted.

For a given extension length of the handle 32 Here is the drawstring stretched twice as strong, so that there is a higher progression than in the first embodiment. It is understood that the handle 32 rotatable on the bearing for the pulley 44 can be fixed so that it is relative to the pulley 44 to rotate about an axis perpendicular to its axis of rotation. In this way it can be avoided that unwanted torques are exerted on the user's hand.

4 shows a further embodiment in which at each end of the drawstring 30 a handle 32 is appropriate. The pulleys 28 are not arranged here on a sleeve, but with snap hooks 46 in eyelets 48 hung at different heights on the pole 12 are attached.

In the embodiments described here, the tension band 30 or 30 ' with the help of the role 34 and the tensioning cable 36 on the frame 10 anchored. Alternatively, the anchoring can also be done by the role 34 a sufficiently large weight attached and supported at an adjustable height. The extraction of the drawstring then causes first an elongation of the drawstring, with a corresponding progression of the restoring force, and then lifting the on the roll 34 hanging weight without further increase in the restoring force.

5 shows a training device according to an embodiment of the invention in combination with a hospital bed 48 , of which only a mattress 50 and a reclining headboard 52 are shown. This training device has two vertical racks 10a at the head and foot of the hospital bed 48 on, as well as two horizontal racks 10b holding the two vertical racks 10a connect together, once at the height of the mattress 50 and once something above the hospital bed.

In each of the racks 10a and 10b is an elastic drawstring 30 Guided meandering over pulleys, similar to the previous embodiments. Similar to in 3 The drawstring runs over a pulley on which the handle 32 is attached. However, the drawstrings are 30 In this example, no endless belts, but the two ends of each drawstring are anchored directly to the trusses of the respective frame. The positions of the handles 32 in the longitudinal direction of the respective frame can be similar to in 1 with pods 24 to adjust.

The training device after 5 allows one on the bedside 48 lying patients to perform a variety of therapeutic exercises in which he handles 32 pulls upwards or downwards or horizontally in a vertical direction to strengthen the arm or chest muscles. Likewise, the patient can handle 32 , the vertical frame 10a is assigned at the head end, with your feet off (or instead of the handle 32 a handle converted to a foot plate) to strengthen the leg muscles. The vertically extendable handles can also be operated with the legs (after the sleeves 24 moved to the foot).

This in 5 shown exercise equipment may be in the direction of the width of the hospital bed 48 be arranged centrally. Optionally, however, two similar training devices can be placed to the left and right of the bed, so that exercises with both arms and / or feet can be performed simultaneously.
