The present invention relates to the field of equipment and devices for the development and training of muscles or joints by force-acting resistance with or without measuring devices. The invention solves two problems, namely the problem of more faithful transmission of limb movement to the device / device for exercise, or transfer of movement of the device / device for training to the extremity, rehabilitation or diagnostics, and the problem of removing most of the unwanted load on the joint , rehabilitation or functional diagnostics.

Description

Technical field to which the invention relates

The invention belongs to the field of equipment and devices for the development and exercise of musculature or joints by applying force against resistance with or without a measuring device. According to the international patent classification, the invention is classified in A63B 21/00.

Technical problem

Exercise, functional diagnostics and rehabilitation can in principle be performed with two types of load, i.e. a free load (e.g. lifting weights or pulling a rope) where the load enables the movement of the limb or body in all directions or by moving the lever of the device/exercise device where the movement of the limb is limited by the given axis of rotation of the device or another form of guidance. When exercising or diagnosing using a lever, the limb can only be moved in the manner and in the direction in which the lever of such a device moves. When performing a movement with a free load, the limb moves along an arbitrary trajectory of the exerciser. However, during exercise, functional diagnostics or rehabilitation of limbs on devices and devices on which the user exercises so that his limb makes a semicircular movement of the lever of the device / device, or the device / device moves the limb of the user in a semicircle over the lever, the movements of the extremities on such devices are performed in the following manner that the lever that moves due to the force of the limb or the force produced by the device itself rotates around a certain axis formed by the point of attachment of the lever for the device/device for exercise, rehabilitation or diagnostics. In principle, the movement of the limb functions as a mechanical rotation around the joint, which forms a fixed point of fixation of the limb.

In this case, there are two axes of rotation, one represented by the axis of the lever of the device and the other represented by the axis formed by the joint of the limb that is attached to the lever. However, considering that the axis around which the limb rotates and the axis around which the lever of the device rotates do not necessarily pass through the same imaginary direction in space at all times, during the movement of the limb attached to the lever of the device, there is a gap where the point of contact between the limb and the lever of the device cannot describe the same curve in relation to the mentioned two axes of rotation. On the existing levers of such devices, given that they are fixed without the possibility of rotation at the point of receiving the extremity or the impossibility of sliding the receiving extremity parallel to the extremity, the user experiences a load in the extremity due to the mechanical law that every point that rotates around a certain axis tends to keep such movement in such a way that it is equidistant from the center of rotation. Such a way of moving reduces efficiency, affects the precision of measurements, and can lead to unnatural loads and thus to injuries.

State of the art

A search of the state of the art, specifically the PATENTOSCOPE and ESPACENET patent databases, shows that levers as parts of devices for exercise, training and functional diagnostics similar to the one that is the subject of the invention are not subject to patent protection nor are they in commercial use. Namely, it is a lever that ensures the most faithful monitoring of limb movements so far in relation to the measurement of power, speed and moment parameters, which represents a significant departure from the state of the art and previous knowledge about the possibilities of registering the actual moment of the limb muscles on registration devices, thereby increasing efficiency exercise and reducing the possibility of injuries.

Brief content of the essence of the invention

The subject invention relates to a lever with a slider that solves the primary problem of achieving the conditions of faithful measurement of movement parameters and strength of the limb, whether the limb performs isokinetic, isotonic, or isometric exercises, in a concentric or eccentric manner, or their combinations.

The secondary problem that is solved by this invention is the relief of the joint of the limb that is subjected to exercise / testing / diagnosis, because the grip of the lever adapts to the limb throughout the movement of the limb in such a way that it moves along the path along which the limb also moves. At the same time, there is no overcoming of resistance or strain as in a situation where the extremity moves in one path, and the reception of the extremity follows a close but completely different path.

A lever with a slider that is installed in devices and devices for exercise, rehabilitation and functional diagnostics of the extremities consists of:

- accepts on the shaft of the device or device on which it is installed,

- one or more slide guides,

- guide stops,

- a slide that consists of a slide support and a slide shaft attached to it, where the slide stop and the slide shaft key are located on the slide shaft, between which the limb grip is movably placed on the slide shaft;

where the slide is movably located on the slide guides by means of the slide support;

and where said lever with a slider enables the movement of the point of connection of the limb and the receiving limb around the axis of the joint of the limb.

The slide shaft key prevents the limb socket from falling off the slide shaft, while the slide stop ensures the necessary functional distance of the limb from the slide lever. Furthermore, the function of the slide shaft key is to prevent the extremity grip from rotating more than necessary about the slide shaft without making it difficult to use.

One or more slide guides are connected at one end to the holder on the shaft of the device or device on which the lever with the slide is installed, while at the other end the slide guides are embedded in the guide stop to ensure the rigidity of the slide guides and to prevent them from falling out sliders from the guides. It is preferable that the guides are profiled in such a way that they allow only linear movement of the slider along them and that their profile does not allow the slider to rotate around the axis of the guides. Furthermore, it is preferable that the lever with the slider contains two guides.

It is preferable that the axis of the slider is laid vertically in relation to the guides of the slider. Likewise, it is desirable that the limb holder can rotate around its axis and can slide to one side or the other in the direction of the axis of the slider axis, whereby the range of linear movement is determined by the position of the slider stop at one end and the limb holder key at the other end. Furthermore, it is preferable that the support on the shaft is made of a permanent and stable material such as metal, plastic or other material.

The shaft mount can be rounded, partially arched, or in any other design that reflects as faithfully as possible the parallelism with the line of the extremity, as suits the designer the most, while maintaining the functionality of the lever with a slide on the shaft of the device/exercise device. , rehabilitation or functional diagnostics.

In one of the embodiments of the subject invention, it is possible for the slider support to have one or more linear bearings that are installed for the best possible movement along the guides.

Also, the extremity support can have a built-in linear bearing with the aim of making it slide or rotate around the axis of the slide as well as possible.

Fixation of the limb in the limb holder can be performed in various ways - in the preferred version, a "velcro" tape is fixed at the two ends of the limb holder, while the tape, if the limb holder is from the front, secures the limb from the back and vice versa. Another possible method of fastening is the system used to fasten and adjust the length of the rope in the equipment of sailboats, such as the Cam Matic system developed by the company Harken.

This invention solves the mentioned problems in such a way that the extremity moves around the joint as its axis, and the point of connection of the extremity and the reception of the extremity of the device for rehabilitation, training and functional diagnostics, with regard to the realized elements of mobility, also moves around the axis of the joint, and not around the axis on which the lever of the device is attached. Therefore, the curves in space that describe the points of connection of the limb and the connection of the attachment of the limb, where one point is located on the limb and the other on the attachment of the limb, are identical. This results in the most faithful transfer of limb movements to the lever, and thus the most faithful representation of the measured characteristics of the musculature of the limbs.

On the other hand, the joint of the extremity is relieved by the pressure created on it by the lever that was fixed to the extremity. This ensures that the actual torque produced by the muscle of the limb is registered on the torque recording device.

The slider lever is primarily intended for use in highly sophisticated devices for training, rehabilitation and functional diagnostics, but it can also be used in other less sophisticated devices when the user wants to take advantage of this invention.

Thus, this invention can be applied to devices and devices for exercise, rehabilitation and functional diagnostics, such as, for example, devices manufactured by CON-TREX, BIODEX, CSMI, or ISOMED2000, and specifically deals with the problem of transferring limb musculature movements to the device in a way that minimizes the impact on the joints and bone system that support the muscles that exercise (or are the subject of rehabilitation or functional diagnostics).

A detailed description of at least one way of realizing the invention

The invention is realized in such a way that the attachment to the shaft (10), made by machining from a piece of steel plate, is permanently attached to the shaft of the exercise device, which is also the shaft of the servo motor, in a convenient way. The attachment to the shaft (10) is made rounded, partly in an arc, in a way that reflects the line of the lower limb as faithfully as possible, as shown in Figure 1, with the fact that the functionality of accepting the lever with a slider (30) on the shaft of the device / device is preserved during shaping. for exercise, rehabilitation or functional diagnostics.

At the lower end of the receiver, two round steel slide guides (12) with a high level of surface treatment are installed on the shaft (10), and they are firmly inserted at the lower end into the guide stop (14) made of steel, which forms the lever (30). The slider (35) is made by connecting the following machined steel elements with each other with a detachable connection, namely the slider support (16), the slider stop (18), the extremity receiver (20), the slider shaft key (22) and the slider shaft (24) at where the mentioned elements are interconnected in such a way that the slider support (16) is fixed to the slider shaft (24) on one side, the slider stop (18) is fixed to it, then the limb holder (20) that slides along the shaft is placed on the shaft of the slider and can rotate around it, with the free end of the slider being locked fixed with the slider shaft key (22). The assembled slide (35) is then placed on the slide guides (12), which are fixed from the bottom with a guide stop (14) so that the slide does not fall out of the slide guides. In doing so, the slide shaft (24) is firmly fixed vertically to the slide support, and the slide shaft key (22) is installed on the side of it that is further from the slide guides, while the slide stop (18) is installed on the side closer to the slide support. The slider (35) can be moved along the guides from the point of connection of the guide and is accepted on the shaft to the point of connection of the guide and the stop of the guides. The slider support (16) has built-in linear bearings, one for each slider guide.

The limb support (20) moves along the slider axis (24) linearly in the direction of the axis of the support support with the possibility of partial rotation around the axis of the support support, as far as the slide shaft key (22) allows. The extremity support has a built-in linear bearing with the aim of making it slide or rotate as well as possible around the axis of the support support.

Fixation of the extremity in the extremity support (20) is performed with a "Velcro" tape, whereby it is fixed at the two ends of the extremity support.

One way of using a lever with a slider is shown in Figure 2. The lever with a slider, shown in this case for exercise / rehabilitation of the left knee, is installed on the shaft (50) of the servomotor (40) or the actuator / dynamometer, which is an integral part of the device / device for training. At the same time, it can be fixed to the chair on which the person is sitting, or it can be a separate part of the device. The lower leg of the left leg is fixed in the limb holder.

In another possible embodiment used for training the lower leg of the right leg, the lever with the slider is mirrored to the lever with the slider for training the lower leg of the left leg.

In the third possible embodiment, for the purposes of training/rehabilitation of the pelvic muscles, a lever with a slider installed on the servomotor (40), while the exerciser is in a standing position for exercise, is attached to the upper part of the upper leg.

In the fourth possible version, when the exerciser lies on his stomach, the grip of the lever limb with the slider is fixed to the limb (lower leg) in such a way that it is always on the back side of the lower leg on the side where the exerciser has to overcome greater resistance.

In the fifth possible embodiment, the limb attachment can be attached laterally to the limb depending on the muscle group being exercised.

In other versions, a lever with a slider can be used in an appropriate way for the needs of rehabilitation / performing hand exercises, especially for people who do not have the ability to grasp (eg due to the loss of a hand, fingers, etc.).
