Abstract

The invention relates to a gymnastic roll (1) having a lateral surface (4) and a longitudinal axis (A) in a region substantially circumferential with respect to the longitudinal axis (A) around the lateral surface (4) starting from the level of the lateral surface (4) in the radial direction to the longitudinal axis (A) extending towards recess (2) is present.

Description

The invention relates to a gymnastics roll according to the preamble of claim 1.

Various training devices have already been developed for a workout to strengthen the muscles. For example, in the fitness and rehabilitation area, as well as in a variety of sports, the exercises can be performed on specially designed equipment. The goal for many exercises is to strengthen the spinal muscles. The exercises are aimed primarily at strengthening the back, shoulder, arm and trunk muscles.

Pilates or yoga rollers, for example, which are already known for such training, offer versatile and individual exercise options. Such gymnastics rollers for balance and stabilization exercises usually have a dirt-repellent surface, are hygienic and skin-friendly. In addition, they offer versatile uses for training at home, in the gym or in physiotherapy. Even competitive athletes benefit from the outstanding features. The body is thus permanently stabilized.

From the publication DE 1 897 354 U is a training device in the form of a play, sports and gymnastics role of foam known. For balance exercises, the ends of the cylindrical roller are frusto-conical. This creates the opportunity to move standing on the role while also running curves. The actual cylinder is smooth and without further profiling. The end faces are arranged either at right angles to the central axis or have the shape of a spherical section.

Furthermore, from the document DE 1 870 906 U a Fußgymnastikrolle known, through which a better massage of the soles of the feet is achieved, and also the cleaning of the role is simplified. For this purpose, the role in the form of two- or multi-start spirals. Compared to other gymnastic rollers in cylindrical form, the spiral shape achieves an effective massage effect. The foot is exposed to a constantly changing surface and thus subjected to an acting on all sides pressure and stroke massage.

The object of the invention is to develop a gymnastic role of the known kind in order to use them in rehabilitation, therapy or fitness training can.

According to the invention this object is achieved with the features mentioned in claim 1. The other dependent claims relate to advantageous embodiments and further developments of the invention.

The invention includes a gymnastics roll having a lateral surface, in particular end faces and a longitudinal axis, wherein in a region substantially central with respect to the longitudinal axis, at least one recess extending around the lateral surface starting from the level of the lateral surface in the radial direction to the longitudinal axis is arranged or arranged . is available.

The invention is based on the idea of carrying out a gymnastic roll as a therapy or training device with a recess arranged essentially in the middle, in particular with respect to the longitudinal axis or the gymnastic roll. The term substantially centrally arranged recess in this context means that even a slight offset from the geometric Middle of the gymnastics role is conceivable, so as to train body parts in a suitable manner. A recess may also have asymmetrical shapes to best match the body.

This recess, for example in the form of a uniform circumferential recess, has the purpose not to burden certain parts of the body in the application. In other words, the recess is a return of the lateral surface in the radial direction inwards, whereby a reduced diameter or circumference is established in this region. If desired, a desired training effect also results from a more intensive application of force at the points where the body comes into contact with the lateral surface. Thus, the depth, the width and the shape of the recess are adapted to each other for the mechanical stresses occurring during the exercises, so that a treatment of local pain points is also possible.

In addition, the surface may be provided with additional knobs low height or a slightly wavy structure. Thus, the surface of the gymnastic role is much more slip-resistant and grippier than rollers with non-textured surfaces. Materials, such as foams, are particularly suitable for this because they are extremely hard-wearing and durable. The material must maintain its shape and damping properties even with frequent use. In addition, the material should be dirt and water repellent and can be cleaned well.

Thus, with the gymnastic role according to the invention a targeted training of many muscle parts possible, while other body parts, such as the area of the spine, have no contact with the lateral surface and are therefore relieved. In a common embodiment, the gymnastic role in an adapted to individual body parts round elongated Form be executed. All faces can be arranged at right angles to the lateral surface, bevelled or rounded.

A particular advantage of the invention is that the dimension of the gymnastic roll according to the invention is adapted to the nature of the exercises and the physique and thereby remain largely unimpaired body parts without force. Consequently, the gymnastic role is a training or therapy device with a recess for the mobilization of individual body areas, in particular for spinal protection.

A typical use is the training of the spinal column in the upper back area, with which sets a therapeutic effect. The recess ensures, especially in the neck area, that there the spine is exposed to no or only a small load. The gymnastics role can therefore be used from rehabilitation to fitness and competitive sports.

Such a training device is an important starting point for the treatment of the neck area, in particular for physiotherapeutic and sports therapy use. Such devices also allow the combined training for the regeneration of other body parts.

In a preferred embodiment of the invention, the gymnastic roll may have a cylindrical shape. In particular, a circular cylindrical shape comes into consideration. The length of the roller along the longitudinal axis is preferably a multiple of the diameter.

Advantageously, the gymnastic roll may have a length of 30 to 50 cm, preferably 35 to 40 cm and a diameter of 10 to 20 cm, in particular for example 14.5 cm. The dimension of the roles is in the way adapted to the exercises or the body and also suitable for example for self-massage.

Advantageously, the gymnastic role can be performed solid. On the other hand, however, solid or rigid materials with a soft surface coating can also be considered. A massive gymnastics role is particularly stable and also allows circumferential central recesses to a greater depth in the radial direction.

Overall, however, any elastic material is suitable for use. In a preferred embodiment of the invention, the gymnastics role may consist of a closed-cell foam. The density of the foam can here z. B. be about 30, 45, 60 or 120 kg / m ³ .

Preferably, the gymnastic role consist of a cross-linked polyethylene flexible foam. Such materials are very easy to machine mechanically. This foam also desirably contains no halogenated hydrocarbons such as CFC or HCFC.

In a preferred embodiment of the invention, the recess, starting from the level of the lateral surface, in the radial direction by 2 to 5 cm, preferably 3 to 4 cm extend to the longitudinal axis. The absolute depth results for example from the body geometry in the shoulder and neck area of a person. The values given are to be understood as the maximum depth of the recess, the recess being adjusted to the actual body curvature.

Advantageously, the recess may extend in the region of the level of the lateral surface in the direction of the longitudinal axis by 2 to 5 cm, preferably 3 to 4 cm. The recess or recess can therefore in the region of the level of the lateral surface has a width of 2 to 5 cm, preferably 3 to 4 cm exhibit. The width depends on the body part, which should be exposed during training no or only a minimal load.

In a preferred embodiment, the recess may be formed as a rectangular groove. Such grooves are particularly easy to manufacture and, with sufficient depth of use, do not share common undesirable contact points with the body surface.

Further preferably, the cross-sectional area of the recess in the direction of the longitudinal axis may be substantially square. A recess of the same width as depth allows in particular the spine in the upper neck area free.

In a preferred embodiment of the invention, the recess may be formed as a circular groove. A round groove is, in addition to other symmetrical or asymmetric shapes, relatively easy to produce. In addition round grooves form approximately the counterpart to the spine geometry in the upper neck area. As a result, a rather smooth transition from the lateral surface starting to the deepest depression of the groove is created for a groove.

Further advantageous developments and refinements of the invention will become apparent from the embodiments described in principle below with reference to the drawings.

Fig. 1 schematically shows a perspective view of a gymnastics roll according to the invention 1. The gymnastics roll 1 has a cylindrical shape with its longitudinal axis A as the axis of symmetry and has perpendicular final outer end surfaces 3. The non-visible further outer end face is the same. Along the longitudinal axis A, the gymnastics roll 1 has a recess 2, which is caused by a recess in the otherwise cylindrical lateral surface 4. This results in inner end surfaces 6, which form flat surfaces in the radial direction in this embodiment and intersect the longitudinal axis A perpendicular.

As a detailed view shows Fig. 2 schematically shows a perspective view of a gymnastics roll 1 in the central region with circumferential rectangular recess 2. The lateral surface 4 shows in this central region an abrupt return to an inner core element 5. The inner end face 6 also has a vertical section with the surface of the core element 5th

As another exemplary embodiment shows Fig. 3 schematically a perspective view of a gymnastics roll 1 in the central area with circumferential groove as a recess 2. Here is no abrupt transition from the lateral surface 4 to the core element 5 instead. Such round grooves as recesses 2 are particularly suitable because they form the counterpart to the spine geometry in the upper neck area. As a result, the body geometry is mapped to the deepest depression of the groove. By such symmetrical or asymmetric shapes of the grooves and their width or depth, the force in this area can be adjusted in a targeted manner from zero to a desired low level during training. A force of zero means that there is no body contact with the recess.
