Description

The invention relates to a training belt for strengthening the human trunk and arm muscles according to the preamble of claim 1.

From the prior art, it is known to use expanders to strengthen the trunk, arm and shoulder muscles of a human. These have two rubber-elastic tension elements interconnected handles, which can be grasped and pulled apart with the hands.

Furthermore, from the DE 20 2013 002 975 U1 a Armzug belt known in which a tension-train system with guide rollers and at least one guide roller is used, which is housed in a housing with at least one spring and at least one cord drum, which against the spring forces by at the ends of Cord attached handles can be rotated. Due to the size and the pulleys described Armzug belt is cumbersome to handle and is therefore not suitable to be worn unobtrusively under a jacket. In addition, the belt can be used due to its design and size while jogging only with greater restrictions, in addition to the leg muscles and the torso, arm and back muscles to train.

Accordingly, it is an object of the present invention to provide a training belt which avoids the disadvantages of the prior art and which can be carried during running training and used to train the arm and trunk muscles in addition to leg muscles.

This object is achieved by a training belt with the features of claim 1.

Further features of the invention are described in the subclaims.

According to the invention, a training belt for strengthening the trunk and arm muscles comprises a base body having a back portion and two opposing side portions projecting from the back portion, the ends thereof for fastening the training belt in the waist region of a human person via closure means, in particular one or more belt belts known from belts ago, are connected to each other. The training belt according to the invention is characterized in that it comprises an expandable tension member made of a rubber-elastic material having a first and a second end, which is fixable on the back portion and guided over the side portions. The guide can in this case, for example, via one or more attached to each of the side sections eyelets or sleeves. At the first end and at the second end of the expandable tension element, a first or second grip element, which can be gripped by the hands for expanding the tension element, is furthermore fastened in each case.

The use of the training belt according to the invention has the advantage that training of the trunk muscles during walking, walking and jogging can be done almost anywhere and at any time. This can be exercised by different exercises, which will be discussed further below, almost the entire trunk muscles of a human, especially in the area of the back / back muscles, which can be achieved in an advantageous manner an upright posture and a secure state. Another advantage of the invention is the fact that the complete additional training of the trunk and arm muscles in an upright posture while walking, Walkens and / or jogging can be done, resulting in a shortening of the training times, as the different muscle groups of the leg area as well as the upper body area can be trained simultaneously.

According to a further idea underlying the invention, the back section has an adjusting and fixing device, by means of which the length of an expansion section of the expandable tension element defined between the grip elements and the adjusting and fixing device can be changed. hereby results in the advantage that can be used as expandable traction elements comparatively inexpensive and preferably provided with a textile cover expander rubbers, in which the length of the Expansaionsabschnitte, ie the sections which extend from the adjusting and fixing device to the respective gripping elements, can be adapted to the respective arm length of a person exercising in a very short time. In addition, can be changed by the choice of cross-section and / or the rubber hardness of the expander rubbers preferably used, which are known to be offered in different configurations on the market, the required minimum force to expand the respectively used expandable tension element in a simple manner. This makes it possible for the training belt according to the invention to be adapted to the greatest possible extent flexibly and with little effort to the height and physical requirements of a person to be trained, in particular to the different basic muscle strength and arm length.

Another advantage is the fact that can be tracked by an appropriate choice of the length of the expansion sections in conjunction with a correspondingly chosen spring constant / hardness of the rubber material different physiological training goals, such as a targeted training of speed, the maximum force or strength endurance, as well as fat burning etc ..

In the preferred embodiment of the invention, the adjusting and fixing device has at least two deflecting elements, via which the expandable tension element can be guided to form loops of different loop length. This makes it possible that by forming one or more loops with more or less large loop lengths, the length of the expansion portions of the expandable tension member can be easily adapted in a short time to the respective arm lengths of the exercising person.

According to another idea on which the invention is based, a change in the length of the expansion sections can advantageously be obtained particularly simply and quickly by clamping the expandable tension element preferably in the center or in the middle of the adjusting and fixing device by a clamping element is, which is preferably supported for this purpose on the base body, or is added to this. The clamping element can be formed, for example, by a constriction / clamping gap which is formed on the back portion of the main body, and which has a smaller width than the diameter of the expandable tension element, so that it can be pressed with the fingers from the outside into the clamping gap fix this in the desired position.

In the preferred embodiment of the invention, the deflecting elements are peg-shaped elements which are arranged on an intrinsically rigid base plate, for example a plastic plate, along at least two rows at a distance from each other. The distance is in this case selected so that the expandable tension element can be passed between two pins, which, however, may also have a slightly smaller distance than the diameter of the tension element, ie that these also act as clamping elements which fix the expandable tension element in the region of the back portion , This results in the advantage that the formed loop-shaped sections, which lead to a shortening of the expansion sections relative to the maximum section length, can be reliably fixed to the inherently rigid base plate, so that falling out of the formed in the non-expanded position of the respective expansion sections of the expandable tension element loop-shaped portions of the tension element is reliably prevented.

In the preferred embodiment of the invention, it is further provided that on the opposite side of the adjustment and fixing device fastening means, in particular in the form of Velcro strips are attached to which cushion elements of different sizes and / or thickness can be releasably secured. This has the advantage that the training belt according to the invention can be flexibly adapted to different diameters and anatomical shapes of the hips of the waist region within a very short time.

According to another underlying idea of the invention, the grip elements are preferably rod-like and each have at one end a joint on which the associated free end of the expandable tension member angularly movable can be attached, or is attached. The first and second handle members may in the simplest case be rod-shaped wooden or plastic handles on which the hinge may be formed as a rotatable pin which extends through a slit-shaped recess in the handle member, and around which the first or second, preferably one Loop shaped end of the expandable tension member is guided around.

Although the gripping elements can also be embodied as closed handles, the above-described rod-shaped design has the advantage that the hand muscles can additionally be exercised by the angularly movable arrangement of the bar at the first and at the second end of the traction element. Thus, with an arrangement of the rod-like gripping elements at a 90 ° angle to the pulling direction of the expandable tension element only a small holding force by the fingers of the rod-like grip element embracing hand to apply, whereas when aligned in the longitudinal direction of the expandable tension member, a high grip force is required to To hold the rod-like handle member by hand in the expanded position of the tension member without the free end of the handle member slides out of the hand.

According to another idea underlying the invention, the expandable tension element may be guided on the first and on the second side section via a sliding guide, which preferably comprises a sliding surface attachable to the respective side section and a sliding body attachable to the tension element, which is moved along the sliding surface, if the respective one Expansion portion of the expandable tension member is moved over the convex curved due to the convex curve of the lateral waist region sliding surface. The sliding surface is preferably designed as a plastic surface, in particular as a plastic film, which may be, for example, a tear-resistant fabric film, for example provided with a Teflon lubricious coating plastic film or a plastic fabric film like a truck tarpaulin. This can either be releasably connected by means of a Velcro fastener or snaps with the associated side portion, or be glued or sewn onto this. Through the use of a respective sliding guide in the region of the first and second side section, there is the advantage that the service life of the expandable tension element guided over the first and second side sections is considerably increased, because of the Sliding a friction chafing of the expansion sections of the expandable tension element is effectively prevented.

In a further embodiment of the invention, which is particularly well suited for training the back arm and shoulder muscles, a back pull element for strengthening the back muscles and back arm and shoulder muscles of a person can be arranged on the first and on the second side section. This has in each case a further expandable tension element, which is preferably also designed as a known expander rubber, one end thereof on the associated side portion, for example, on a mounting lug thereof, and the other end is attached to a fastened to the upper arm of the exercising human arm loop. The attached to the respective arm loops and to the respective first and second side sections further expandable tension members made of rubber-elastic material have a substantially smaller length than the expandable tension member, the length is chosen so that the other expandable tension elements predominantly, or only then stretched be and generate a counter force when the associated expansion portion of the expandable tension element is relaxed in the backward movement of the respective arm.

For this purpose, the arm loops are preferably fastened in the region of the arm bends on the upper arm of the exercising person; and the further expandable tension members are connected via eyelets and hooks angularly movably connected to the associated first or second side portions and the respective arm loops.

In order to prevent the training belt according to the invention from slipping upwards during the training, especially in the case of the last-described embodiment of the invention in the rearward upward movement of the right or left arm, leg loops can additionally be fastened to the side sections of the main body, with the aid of which the main body expands the expandable tension element , or the other two expandable tension elements against an upward movement can be fixed. The provision of leg loops leads to the further advantage that during a movement of the first and second handle in the lateral direction in front of the body to the targeted Training the chest muscles twisting the training belt of the invention in the waist area can be reliably prevented.

The invention will be described below with reference to the drawings with reference to a preferred embodiment.

As in the Figures 1 - 3 1, a training belt 1 for strengthening the trunk and arm muscles 110, 120 of a human person 100 has a base body 2 which has a back section 4 and two opposing side sections 6a, 6b which are used to fasten the training belt 1 in the waist region 115 via closure means 10a, 10b in the form of a belt buckle 10a, 10b can be interconnected. As the representation of FIGS. 1 and 3 can continue to be removed, the training belt 1 of the invention further comprises an expandable tension member 12, which is preferably formed in one piece and consists of rubber-elastic material. The expandable tension element 12 hereby has a in Fig. 3 indicated first end 12.1 and second end 12.2, where respective handle elements 14.1 and 14.2 are fastened, which can be grasped by the exercising person after folding the training belt 1 according to the invention around the waist and closing it by means of the belt buckles 10a, 10b with the hands 130.

As based on the presentation of the Fig. 2 Furthermore, the training belt 1 according to the invention has at its back portion 4 an adjusting and fixing device 16 which comprises a plurality of preferably peg-shaped deflection elements 16.1, 16.2, around which the middle part of the tension element 12 can be guided in the form of loops. In this case, in order to fix the expandable tension element 12 in the region of the center during the alternating expansion of the two expansion sections 12a, 12b, two of the peg-shaped deflection elements 16a, 16b may be spaced apart from each other by a clearance which is smaller than the diameter of the cross-sectionally preferred circular expandable tension member 12 made of rubber-elastic material. In this way, the tension element 12 between the two peg-shaped elements 16a, 16b are frictionally clamped, so that the tension element 12 is clamped in the region of its center by the two clamping elements 16a, 16b on the back portion 4. The clamping ensures that the expandable tension member 12 does not slip relative to the spine portion upon alternately tensioning and relaxing the first and second expansion portions 12a, 12b, so that the restoring force of the rubber-elastic expansion portions required for the training is reliably provided.

The deflecting elements 16.1, 16.2 are preferably arranged in two separate rows, in order to be able to place a plurality of loops around the deflecting elements 16.1, 16.2, if desired, by means of which the length of the expansion sections 12a, 12b is correspondingly shortened.

As the representation of Figures 2 and 3 can still be removed, the peg-shaped deflecting elements 16.1, 16.2 are preferably added to an inherently rigid base plate 17, which may be, for example, a plastic plate on which the peg-shaped elements 16.1, 16.2 can be integrally formed, in particular by injection molding. Alternatively, it may be provided that to reduce the friction between the tension element 12 and the peg-shaped deflection elements 16.1, 16.2, over which the tension element 12 is guided, one or more of the deflection elements 16.1, 16.2 are designed as rotatable pins. These may include, for example, a fixed core connected to the base plate 17 and a sleeve rotatable on the core, which contacts the tension element 12.

The training belt 1 according to the invention also has on its side of the base body 2 opposite the adjusting and fixing device 16, i. On the back of the exercising human person 100 facing inside of the body 2 attachment means in the form of Velcro connection pads 18, by means of which cushion elements 20 different size and / or thickness can be attached to the inside of the body 2 to the training belt 1 according to the invention to adapt in a flexible way to different waist shapes and waist diameter.

As shown by Fig. 3 the grip elements 14.1, 14.2 in a further embodiment of the invention are rod-shaped and have at their ends in each case a joint 22 to which the respective free ends 12.1, 12.2 of the expandable tension member 12 can be fixed angularly movable, so that the rod-like grip elements 14.1, 14.2 either, as in Fig. 1 shown when expanding the tension member 12 with the arms in the forward direction directed or alternatively 90 ° upwards in an angled position (not shown) can be maintained.

As the representations of the FIGS. 1 and 2 can further be seen, the expandable tension member 12 is guided in the region of the first and second side portion 6a, 6b during clamping and relaxing the respective expansion portions 12a, 12b in the region of the first and second side portion 6a, 6b via a sliding guide, for example, one in the 6 and 6, or a sliding surface 26 fixed to the respective side section 6a, 6b, which is preferably a plastic film which may be provided with a friction-reducing coating over which the respective region of the first and second expansion sections 12a, 12b expand expandable tension member 12 slides. The metal eyelet is here in addition ensures that the respective expansion portion 12a, 12b of the expandable tension member 12 does not slip from the side portions 6a, 6b upon upward or downward movement of the arms. Furthermore, a sliding body 28, for example, a friction-reducing plastic sheath can be arranged on the tension element (12) itself, via which the respective expansion section 12a, 12b is supported on the sliding surface 26.

According to the presentation of the Figures 2 and 3 It may be provided in a particularly preferred embodiment of the invention that at the first and second side portion 6a, 6b, a back pull 30 for strengthening the back muscles and back arm and shoulder muscles 120, 125 of a human 100 is provided, each having a further expandable tension member 30a , 30b comprises a rubber-elastic material, but compared to the tension member 30 has a much smaller length. Here, each one ends of the other expandable tension elements 30a, 30b are attached to the associated side portion 6a, 6b, for example via carabiner hooks on unspecified further eyelets, whereas the other ends of the expandable further tension elements 30a, 30b on an arm loop 32 are attached angularly movable, which are attached to the right and left upper arm of an exercising person 100, as shown in the FIGS. 1 and 2 is indicated. The length of the further expandable tension elements 30a, 30b is in this case selected so that upon a backward movement of a respective arm beyond the vertical position, an expansion of the respective further rubber-elastic element is effected, as shown in FIG Fig. 2 for example, for the right arm and the further expandable tension element 30a is indicated. By contrast, during the forward movement of an arm, the associated further expandable tension element is preferably fully relaxed, so that the retraction force directed counter to the forward movement of the arm is produced exclusively by the associated expansion section 12a, 12b of the expandable tension element 12.

Finally, the training belt 1 according to the invention may optionally further be provided with leg loops 34a, 34b, which are preferably attached to corresponding eyelets or by means of Velcro fasteners or the like on the side sections 6a, 6b of the Base body 2 are releasably secured, so that this, as in Fig. 1 shown during training around the front hip area and the buttocks area around and thereby prevent twisting of the training belt 1 according to the invention in the alternating expansion of the respective expansion portions 12a, 12b of the expandable tension member 12.

The leg loops 34a, 34b described above also serve to generate a corresponding counterforce when using the back pull members 30, which counteracts a slipping up of the training belt 1 in a rear upward movement of the right or left arm.

The same applies to a lateral upward movement of the arms in the use of the back pull members 30 for training the upper shoulder and neck muscles, for which both arms are alternately or jointly moved away from the body in the upward direction.
