Sports or fitness equipment

The present invention relates to sports or gymnastics equipment comprising at least one roughly rod-shaped oscillating body which is articulated in one area on at least one base body of the equipment, further comprising at least one holding element provided in the lower area of the equipment with contact areas for the feet of a person on the equipment sitting person, the device is also designed so that the person training on this person can train in a sitting position.

A training device is known from EP 2 804 677 B1, in which two articulated levers are provided which can be moved towards and away from the person exercising, with the person exercising on the device in a sitting position and the Person places their feet on pads that are located in the foot area of the training device. In contrast to most well-known cross trainers, the gymnastic exercises on this device are not performed in a standing position, but in a sitting position. The exercises that are carried out on this training device are therefore primarily intended for training the arm muscles. However, in this known training device, the base body consists of a rectangular housing and the holding element comprises a horizontal base plate with two elongated inner edges that enclose the housing of the base body over its entire length and are connected to the base body with screws, so that when the base body is assembled and base plate are firmly connected and fixed in their position relative to each other. The training device is quite large overall and its concept is not designed to be dismantled by the user. Consequently, it is comparatively heavy and takes up a lot of space in a living room even when not in use when used in the private sector.

Based on the aforementioned prior art, the object of the present invention is to provide a training device with the features mentioned above, which also allows the user to use it in a sitting position, but which has a simpler structural design and is easy to disassemble and transportable and offers the user a more versatile range of uses during training. The solution to the above problem is provided by a sports and gymnastics device according to the invention of the type mentioned at the beginning with the features of claim 1.

According to the invention it is provided that the holder element can be positively and releasably connected to the base body and the at least one base body is arranged displaceably relative to the holder element along a longitudinal axis of the holder element.

The holding element can be connected to the base body, for example, via a tongue and groove connection, that is to say, for example, by simply pushing the holding element into a groove in the base body. This connection can be made very quickly and without tools and can be released by the user at any time with a simple movement. The holding element can be a flat board, for example, which is pushed into a correspondingly shaped and dimensioned groove in the base body. The base body can be a comparatively small, simple component which rests in the floor area and, in the case of the device according to the invention, essentially only has the task of forming a receptacle for one (lower) end of the approximately rod-shaped oscillating body, which is positioned at its lower end in the Base body is held and relative to this can be moved in an articulated manner. The connection between the base body and the oscillating body can also preferably be released without the use of tools, i.e. the lower end of the oscillating body can simply be pushed into the receptacle of the base body and is held in place during use by the User exerts pressure on the vibrating body from above. Thus, the sports or gymnastics device according to the invention consists of only a few components and can be easily dismantled and put away to save space when not in use or, for example, transported in a simple sports bag.

According to a preferred development of the invention, the holding element and the base body lie on the floor when in use and the distal end of the rod-shaped oscillating body seen from the user is articulated in a region near the floor of the base body.

The sports device according to the invention is preferably made of wood, and the joint of the sports device can be made of a metallic material.

Preferably, according to a further development of the invention, a joint that connects the base body and the oscillating body in an articulated manner is a ball joint and this ball joint has a first joint element, which is arranged on the base body of the sports device, in the form of a joint socket, and a second Joint element has in the form of a joint ball, which is arranged on the vibrating body of the sports device. here The device according to the invention differs further from the prior art, since the oscillating body can not only perform movements in one plane, but in any direction due to the ball joint. The articulated connection between the oscillating body and the base body is also not in the upper area of the base body, but near the ground, which means that the oscillating body can be made longer and the user has a longer lever when attacking the opposite (upper) end of the oscillating body when he uses the Oscillating body moves in its ball joint storage.

A ball joint also offers the advantage that the joint socket can have a locking device in order to prevent the joint connection from becoming unintentionally loose. This can be done by different configurations of the joint socket. For example, the joint socket can have a lock or a snap connection that prevents the joint ball from loosening by means of a form fit, force fit or a combination of these.

Alternatively or cumulatively, the joint socket can also have a depth that exceeds the diameter of the joint ball. As can be seen immediately, such an embodiment can be advantageously implemented on the piece of sports equipment if the oscillating rod or joint ball is held in the base body or in the joint socket purely by the force of gravity acting on the oscillating body. It is particularly advantageous for the piece of sports equipment if the depth of the joint socket exceeds the diameter of the joint ball by approximately one and a half times the diameter of the joint ball. In such an embodiment, the second joint element is a cylindrical bore. In order to avoid unintentional loosening of the articulated connection, a second articulated element designed as a cylindrical bore can also have a taper on the side facing the first articulated element, which is only slightly smaller than the diameter of the first articulated element.

Furthermore, it is advantageous for the sports device if the oscillating body has a rod-shaped base body and the first joint element and/or the second joint element is arranged coaxially to a longitudinal axis of the base body. In this respect, a piece of sports equipment is made available which offers the advantage that the oscillating body can also be used as a handle at the same time and can be used flexibly to the effect that the oscillating body can be gripped at any position on the base body. The use of an additional handle for the user is therefore obsolete. Since the sports equipment is also to be used to mobilize physically handicapped people, for example, the weight of the oscillating body is of secondary importance, but it is possible as an alternative or in addition to the aforementioned features to use the main body of the Oscillating body made of different materials, such as plastic or metal to run as a training goal, if desired, even a light weight training can.

As already explained above, it is advantageous for the sports device according to the invention to have several degrees of freedom of movement. In this respect, it is particularly advantageous if the joint has at least two axes of movement. The advantage results from the fact that a flexible movement sequence in several directions and different exercise variants are possible while using the sports equipment.

In addition to or as an alternative to the aforementioned features, the sports equipment can have a centering device and/or a locking device and/or a damping device in order to make the use of the sports equipment even more flexible. A centering device means a device by means of which an automatic return of the oscillating body to a central position is made possible. This can be done, for example, by using a number of springs, by means of which the oscillating body can be held in a middle position. The use of such a centering device also imposes a force on the oscillating body, which the user must overcome when using the sports equipment. In this respect, a centering device can also be used as a loading device. Alternatively or cumulatively, the oscillating body can also be locked in a predefined position or in a flexible position by means of a locking device. In this respect, a locking device can be a brake or a locking device. This makes it possible to carry out further exercises on the piece of sports equipment, in which it is necessary to fix the oscillating body. It is also possible to provide a damping device which combines the advantages of a locking device and a centering device in that a position of the oscillating body can be maintained and movement of the oscillating body is only possible with an application of force.

A preferred further development of the invention provides that the oscillating body has at least two sections which are arranged in an axial extension to one another and which can be connected to one another via a screw connection which can be detached if necessary without tools. This has the advantage that a longer oscillating body can be used, but this is formed from several sections that can be dismantled, so that the oscillating body can be disassembled into its sections by the user and the dismantled oscillating body has a shorter overall length, which makes it easier to transport is cheaper. For the screw connection, for example, use screws at the end of one section and a thread at the end of the other section of the rod-shaped oscillating body, so that the two sections can be screwed together by hand by one or rotates both sections about their axis. In the same way, the rod-shaped oscillating body can also be dismantled into three or more sections.

The base body and the holding element preferably have a non-positive connection. The base body preferably also has an approximately spherical envelope surface.

A preferred development of the invention provides that the holding element comprises two approximately plate-shaped support areas for the user's feet, which are arranged at a distance from one another on both sides of the base body and are each spaced apart from it can be connected in a form-fitting and detachable manner transversely to this strip of the holding element, wherein the plate-shaped support areas can be detachably connected to the holding element, preferably via a tongue and groove connection. It is advantageous that the two plate-shaped support areas can be connected to the holding element in the same way as the at least one base body, for example via a dovetail groove by simply sliding it on, so that both the two plate-shaped support areas and the base body can be attached to a simple strip or can push a board, which serves as a holding element.

A preferred further development of the present invention provides that there are at least two oscillating bodies which are spaced apart from one another and can be moved in an articulated manner independently of one another and which are each attached to a base body of the device assigned to the respective oscillating body. In this variant, therefore, two base bodies are used, both of which can be pushed onto the same, for example, strip-shaped holding element and are positioned at a distance from one another and are therefore arranged near the ground. Each of these base bodies can then accommodate a lower end of an oscillating body. The user can then, for example, perform exercises in which he moves one oscillating body forwards and the other oscillating body backwards, similar to a cross trainer, ie moves both oscillating bodies in opposite directions in order to activate the muscles in both arms.

In this variant, according to a preferred development, it is particularly advantageous if a clamping device is provided at the respective proximal end of each of the oscillating bodies. For this purpose, an elastic band can be used, for example, which is attached to the proximal end of the roughly rod-shaped oscillating body on which the user grips. Then, when the user moves the vibrating bodies, the elastic band attached to them is stretched by applying a tensile force, and the user has to apply this tensile force by holding the upper ends of the vibrating bodies moves, so that the arm muscles are more stressed and trained. If the user moves the two oscillating bodies in opposite directions, the result is an arm movement similar to that of a cross trainer.

In the variant of the invention described above, a slit can be made in the proximal end area of an oscillating body, for example, or a slit can be made in the end area of two oscillating bodies and a rubber band or the like can be inserted into such a slit, which is then stretched on two slit bodies when they move apart be moved away. If there is only one oscillating body, one end of such a rubber band can also be attached to a fixed object and then the rubber band can be stretched by articulated movement of one oscillating body relative to the fixed object.

Instead of attaching a jig to the two vibrating bodies, you can attach the jig to another device, such as a fixed wall, for example.

In order to ensure trouble-free movement of the oscillating body, the sports device according to the invention can be designed in such a way that the base body has a spherical envelope surface. In this respect, it is possible to move the oscillating body in all directions of movement without fearing a collision between the main body and the base body.

The present invention is described in more detail below using exemplary embodiments with reference to the accompanying drawings. show it

In the following, reference is initially made to FIG. 1, and on the basis of this the basic structure of an exemplary sports or gymnastics device according to the invention is explained in more detail. The sports equipment designated overall by the reference numeral 1 comprises an elongated holding element 11, which can be, for example, a flat wooden strip or a simple board, which is in a horizontal position near the ground or on the ground, i.e. usually on the floor of a room is placed. The elongate holding element can, as shown in FIG. It is thus possible for the person to put their feet on the holding element 11 and thus put a load on it and keep it on the ground. Furthermore, the sports device 1 comprises a base body 2, which has a dovetail-shaped groove 13 (see Figure 5), for example, on the underside, into which the holding element 11 can be pushed, so that in this way there is a form fit between the base body 2 and the holding element 11. The base body 2 is in the position of use, which is shown in Figure 1, approximately in the middle of the holding element 11, but is not fixed in the transverse direction relative to it, so that the base body 2 can in principle be moved in a guided movement on the holding element 11 can.

The sports device 1 also includes an elongated rod-shaped oscillating body 3, the lower end of which is articulated in a joint receptacle of the base body 2, so that a joint 4 is formed at the lower end of the oscillating body 3. This joint 4 is preferably a ball joint, i.e. a first joint element 5 at the lower end of the oscillating body 3 comprises a ball and the joint receptacle 6 for this ball 5 is located on the base body 2 and has, for example, the shape of a joint socket. In this way it is possible to move the oscillating body 3 in any direction, while its lower end is held with the ball 5 in the joint mount 6 of the base body 2 and thus cannot slip away. If the user takes the upper end area of the oscillating body 3 in his hand, he can move it in the direction of the movement axis marked with the arrows 9 in principle in the transverse direction or in the direction of the movement axis 8 marked with the arrows 8, i.e. towards him or away from you or in any other direction, with only the ball joint with ball 5 and joint socket 6 at the lower end of the rod-shaped oscillating body 3 being given as a fixed point. Further details can be found in FIG. 2, which shows the lower area of the oscillating body 3 in an enlarged view, with the base body 2 being shown here partially in section. It can be seen here that the oscillating body 3 consists of a rod-shaped base body 7 , at the lower end of which the ball 5 of the ball joint 4 is attached via an elongate connecting element 15 . It can also be seen that this ball 5 is accommodated in a part-spherical recess in the base body 2 . It can also be seen that the flat, elongated holding element 11 extends in the transverse direction through the base body 2 on its underside and thus on the bottom side, so that the ball joint 4 with the ball 5 is located above the holding element 11 .

Reference is made below to FIG. 3, in which an exemplary oscillating body 3 of a piece of sports equipment 1 according to the invention is shown in a dismantled state. So that the piece of sports equipment can be stored in a space-saving manner when not in use and can also be transported more easily, the oscillating body 3 here comprises an elongate base body 7, at one end of which is the ball 5 of the joint 4, and a likewise elongate extension section 18, which can be detachably connected to the base body 7 can connect, so that the extension portion 18 extends the base body 7. When not in use, the connection between the base body 7 and the extension section 18 can be released and the two individual parts can be accommodated in a space-saving manner. The connection between these two individual parts can be made, for example, via a threaded pin 19 at one end of the extension section 18, which can be screwed into a threaded hole at the upper end of the base body 7, which is opposite the lower end to which the ball 5 is attached. This connection via the threaded pin 19 can advantageously be designed in such a way that both sections of the oscillating body 3 can be separated by hand without the aid of a tool. At the other end of the extension section 18, as can be seen in Figure 3, there is a slot 20, in which a flat elastic band, such as a rubber band, can be inserted, for example, so that when the oscillating body 3 moves, this rubber band stretches and thus generates a higher force must raise to move the oscillating body articulated.

Further details of the present invention are explained below with reference to FIGS. FIG. 4 shows a plan view of the base body 2 with the joint element 6 which receives the ball 5 at the lower end of the oscillating body 3 in an articulated manner. The base body has an outer and inner side approximately spherical enveloping surface 12 which forms the joint socket 6 .

FIG. 5 shows a perspective side view of the base body 2, from which further details result. On the one hand you can see the groove of the dovetail connection 13 here the underside of the base body, which receives the holding element 11. It can also be seen that there are slot-shaped upwardly open grooves 14 in the enveloping body 12 of the base element 2 on the upper side, these being two grooves 14 which intersect at right angles in the middle of the base element 2 in the shape of a cross. These two grooves 14 are also open to the side. In the middle of the base element 2, the shape of the enveloping body 12 is such that there is a circular opening where the two grooves 14 intersect, so that the ball 5 at the end of the oscillating body 3 can be inserted from above into the opening and the joint socket can introduce. The grooves 14 make it possible for the oscillating body 3 to be guided downwards at very shallow angles without it hitting the wall of the base body 2 .

Reference is made to FIG. 6 below. This view shows the holding element 11, which is pushed into the base body 2 in the transverse direction, as well as two spaced-apart contact areas that are approximately parallel to one another and that each serve to enable the user to place his feet there. In this way, the user has a better abutment close to the ground for each of his feet, so that he can exert pressure with his feet there in order to keep the holding element 11 on the ground if he is subjected to tensile forces or lateral forces by the movement of the oscillating body 3 Base body 2 exerts. The two support areas 17 are preferably attached to the holding element 11 on the outside of the holding element 11 in a detachable manner, in a position in which they are both approximately the same distance from the central base body 2 . They can be displaceable in the transverse direction relative to the holding element, so that the user can select a position of the support areas 17 in which he can comfortably place his feet on the support areas 17 with the correct spacing when in a sitting position.

FIG. 7, to which reference is made below, shows an exemplary embodiment variant of a sports or gymnastics device according to the invention in a perspective side view. The special feature of this embodiment lies in the fact that instead of just one base body 2, which is positioned at a distance from one another, are pushed onto the elongated, strip-like, ground-level holding element 11 running in the transverse direction. A lower end of an oscillating body 3 is inserted into each of the two base bodies 2, so that each of the two oscillating bodies 3 can be moved in an articulated manner. The movement of the oscillating body is such that the joint at the lower end of the respective oscillating body 3 is located as a ball joint in the base body 2, while the user moves the upper end of the oscillating body in different directions. This variant offers the user even more training options because, for example, as shown in FIG use a cross trainer. In doing so, he pushes one oscillating body 3 forward with one arm, while at the same time pulling the other oscillating body 3 backwards with the other arm. In order to increase the forces to be applied when moving the oscillating body 3, according to a further variant of the invention, a connection can be provided between the upper ends of the oscillating body 3 in the form of an elastic band 16, so that when the upper ends of the oscillating body 3 move in opposite directions, the elastic Band is tensioned in each case and the user has to use more force to do so.
