Description

The invention relates to a device for training the muscles, in particular the leg muscles of a person lying down.

After diseases and fractures or even due to a disease-related long bedridden phase and associated muscle loss is often necessary to rebuild the leg muscles. However, these patients often have initial problems moving to stationary exercise equipment. Therefore, exercise equipment is desirable for use in a reclined position. With these patients can train in their early days in their bed, for example, in a rehabilitation clinic, without being laboriously transported to appropriate training equipment. In addition, this also eliminates the risk of transport-related accidents.

In the DE 2 226 980 A Such a training device is presented in which a translationally moving slider is held against by a flat spiral spring. This device has a number of disadvantages, in particular the complex structure and an associated costly production, in addition, the device is very large, heavy and thus unwieldy and not least an adjustment of the spring force is very difficult. Finally, a separate training of both legs is not possible.

In the DE 20 2010 000 355 U1 a training device is proposed, which is suspended by means of a bracket from above into the bed frame at the bed base and in which a foot plate with the weight of an arm located on the bracket with displaceable weight is applied as a counter force. The rotation and thus the force application point is above the bed frame. A disadvantage is also in this device that this is very difficult especially due to the counterweight and thus only conditionally portable, also limits the cantilevered weight arm freedom of movement around the bed and is an accident risk. A separate training both legs is not possible here. Last but not least, the force application point located above the bed frame leads disadvantageously to high leverage forces in the brackets.

The object of the present invention is to provide a training device for training the muscles, in particular the leg muscles of a person lying, which is simple and thus inexpensive to manufacture, small, lightweight, flexible and well adjusted to the needs of the patient.

According to the invention the object is achieved by a device having the features of claim 1, preferred embodiments of the invention are the subject of dependent claims.

The inventive device for muscle training a lying position has four important assemblies.

Mittels der Lösbarkeit wird erreicht, dass die Federkraft durch Wechsel der Federeinrichtung bzw. einzelner Federelemente schnell einstellbar ist. Hierzu ist der Wechsel ohne oder nur mit geringstem Werkzeugeinsatz möglich. Besonders bevorzugt sind hier Hakenverbindungen, eine Schraubverbindung d. h. ein Einschrauben der Federelemente in den Rahmen, eine Fixierung durch Magnetkraft oder auch ein Einrasten mittels Bajonettverschluss.

These are:

• - A fastening device for fastening the device to a solid object. This solid object is in most cases a bed, but can be any vertically arranged frame or plate-like structure. For the sake of simplicity, in the context of this application, the article to which it is attached will be referred to as bed foot.
• - One or two foot receiving devices, usually two will be provided so that a different and separate training of the two legs is possible.
• - A frame that connects the modules, which has a mounting side and an actuating side. On the attachment side, the frame is fastened by means of the fastening device, so that the frame is preferably positioned in the fastened state next to the bed foot. The actuation side is directed to the bed and from this side the foot receptacles are accessible.
• - A releasable spring means which applies the counterforce required for training, wherein the spring means may also consist of several spring elements. By means of the solubility is achieved that the spring force is quickly adjustable by changing the spring means or individual spring elements. For this purpose, the change is possible without or with minimal use of tools. Hook connections, a screw connection, ie a screwing in of the spring elements into the frame, a fixation by magnetic force or a latching by means of a bayonet lock, are particularly preferred here.

According to the invention, at least one foot receiving device, the frame and the spring device are connected to one another in such a way that a translational and / or a rotational relative movement between the frame and the foot receiving device is possible and the spring force of the spring device counteracts this relative movement.

Preferably, the fastening device has two laterally arranged rails, which serve to receive the bed foot. Thus, the device is pushed onto a bed foot. By positioning the frame at different heights different training requirements are possible. This is advantageously a very simple and effective attachment. It is particularly advantageous with this fastening device sliding the device in two positions possible. So you can postpone the device in a rotated position by 180 °, so both with the top and with the bottom first. Advantageously, an increased flexibility for the use of the device is made possible because, for example, in devices that allow a rotational movement, this is trainable both with pivot above and below. This can be different training goals z. B. be tracked to load the toe or heel area. Further preferably, the width of the rails is adjustable to allow adaptation to the width of the bed foot.

Particularly preferably, the rails have a clamping mechanism for fixing the device in a certain height. Thus, simply the height of the device on the bed can be individually tailored to the trainee.

In another preferred embodiment, the fastening device has hook elements with which the device from above on a frame-like structure, such as a bed frame is suspended. The hooks are used in particular to absorb the weight of the device and take hardly moments. Preferably, two supports are provided in the lower region of the frame, which bear against the bed foot, so that the device has a good support on the bed foot. The supports can have a flat or rod-shaped support to rest securely in lattice tube structures or the like.

In a particularly preferred embodiment, at least one foot receiving device has a toe and a heel region and is rotatably connected to the frame in one of the regions. The axis of rotation is largely parallel to the end face of the bed. In connection with the above-described rail fastener, the rotation axis can be easily changed by turning the bed device from the heel to the toe area and vice versa. The spring device may be formed in this embodiment as a peripherally arranged compression or tension spring. Preferably flat or cylindrical coil springs are used. The spring force can be done by removal and / or replacement of the spring elements with high or low spring force. The fixation of the springs is done by positive locking to at least one adjacent component.

As compression or tension springs also coil springs or elastomers can be used. The compression or tension springs are preferably placed in recordings, from which they are easily removed and thus easily exchanged for others. Advantageously, a simple adjustment of the resistance force is made possible by the possibility of replacing.

Preferably, the articulation of the foot receiving device (s) is releasably connected to the frame and so arranged horizontally displaceable on this. Thus, the foot receptacle (s) can be positioned individually for each patient.

In a further preferred embodiment, the spring device consists of several spring elements. These are cylindrical and have at their ends connecting elements for connection to the frame and a foot receiving device. As connecting elements all known possibilities are considered, hooks are preferred for hanging in frame or foot receiving device. In this embodiment, the frame has at least one area surrounding a foot receiving device. Wrapping here means that the area of the frame surrounds the foot receiving device mounted therein via the spring elements at least in a U-shape and the area of the frame is preferably rectangular, optionally open at the top. The foot receiving device is connected via at least three spring elements with the frame. The spring elements are here helical tension springs or elastomers or combinations thereof. Also possible is the use of a damping device within the coil spring.

Particularly preferably, the foot receiving device is connected via four spring elements to the frame, wherein each two spring elements are arranged on the longitudinal sides of the foot receiving device. By longitudinal sides of the foot receiving means are meant the lateral areas of the foot receiving means, not the toe or heel area.

Further, the bias of the spring elements by adjusting the width of the enclosing portion of the frame is preferred. For this purpose, preferably the respective outer strut (ie the left strut of the area for the left foot and the right strut of the area for the right foot) of the enclosing area is designed to be laterally displaceable. The displacement can be implemented, for example, by a threaded rod, which is anchored in the displaceable strut and supported in another strut. In an alternative embodiment, locking means are provided in the horizontal strut, in which the displaceable strut is to be fastened. Due to different lengths of the spring elements, the tread width is also adjustable.

The embodiment described above is particularly advantageous because of its simple structure and the large adjustment options. Thus, different spring elements can be used, whereby a very specific training of certain muscle groups is made possible.

In the embodiment described above, preferably, a horizontal change in position of the foot receiving device (s) with respect to the frame can be achieved by a displaceable arrangement of the vertical inner struts of the enclosing region.

In a further preferred embodiment, each foot receiving device seen in the direction of movement, two consecutively arranged carrier are provided, which are pivotally connected in the direction of movement with the frame. The two carriers are in turn pivotally connected in the direction of movement by a cross member, which is arranged parallel to the frame region between the carriers. Thus, the frame area between the carriers, the carrier and the cross member form a displaceable parallelogram, wherein the displacement counteracts the preferably obliquely arranged in the parallelogram spring means and each foot receiving device is connected to a carrier.

Preferably, the force to be applied by the exerciser and the maximum travel is adjustable by displacement of the foot receiving device on the carrier and thus a change in the length of the lever.

Particularly preferably, the coil springs on a sheath. This has hygienic advantages in hospital use such as requirements for wiping and disinfecting according to hygiene requirements. In addition there are the anti-pinch protection to prevent accidents and the fairing as an optical aspect.

Further preferably, the frame consists of hollow profiles. Such profiles are inexpensive, very readily available and offer good stability with low weight.

Also preferably, the frame is centrally collapsible between the foot receiving devices. Advantageously, the device is even easier to transport and store. The folding is preferably carried out in the direction that does not correspond to the direction of stress during training, so the device is not claimed during training in Klapprichtung.

Further preferably, the fastening means are releasably or hingedly attached to the frame to further reduce the pack size. The solubility can be done for example by means of coarse thread or a simple plug connection.

Preferably, the measuring device is a measuring device separately for each leg, are displayed with the duration and effectiveness of the workout. In this case, events are counted in which a certain adjustable travel of the foot receiving device was covered on the respective leg. Or, the force exerted on the foot-receiving device is measured. The measuring device may be a force sensor or a mechanical device that registers the achievement of a certain spring travel. Preferably, the measuring device is followed by an evaluation unit that processes the data of the measuring device electronically or mechanically.

Furthermore, the subject of the invention is a change system for different versions of the training device. It has a frame with fasteners or with shots for fasteners recordings for training sessions. The training units are arranged in a subframe that can be used in the frame. The connection between the subframe and frame can be effected by means of a tongue and groove connection, wherein the subframe is inserted, for example, from above into the frame, so that the tongue and groove connection engages.

Particularly preferably, the training units are executed with only one foot receiving device and the frame for receiving two subframes. It is thus possible to ensure a high degree of individuality during training with differently executed training units for each leg.
