DEVICE FOR TRANSMITTING A RESTRAINING FORCE DURING RUNNING TRAINING

Abstract

A device for transmitting a restraining force to the body of a runner during running training, including a strap to be wound around the body, and an element for connecting the strap to a tension cord transmitting the restraining force. The connection element engages behind the strap, and upon a body rotation of the runner, rolls and/or glides in the circumferential direction of the strap on the inner side of the strap facing the body.

Claims

1-11. (canceled)

12. A device for transmitting a restraining force to a body of a runner during running training, comprising: a strap to be wrapped around the body; and an element for connecting the strap to a tension cord that transmits the restraining force, wherein the connecting element engages behind the strap and, upon rotation of the body of the runner, rolls and/or slides in a circumferential direction of the strap over an inner side of the strap facing the body.

13. The device according to claim 12, wherein the strap is configured as a nondetachably closed ring.

14. The device according to claim 13, wherein the ring has ends that are not connected together.

15. The device according to claim 12, wherein the strap has, on its inner side of the strap facing the body of the runner has a surface that promotes gripping of the strap on the body.

16. The device according to claim 12, wherein the strap has a circumference greater than a circumference of the body of the runner.

17. The device according to claim 12, wherein the connecting element engages around the strap as an eye.

18. The device according to claim 12, wherein the connecting element is connected to the strap nondetachably in a form-fitting manner.

19. The device according to claim 12, wherein the connecting element has a roller that extends over substantially an entire width of the strap.

20. The device according to claim 19, wherein the roller extends of the entire width of the strap.

21. The device according to claim 19, wherein the connecting element has a metal core encapsulated with plastic material.

22. The device according to claim 19, wherein the connecting element is configured a plate with a cutout for the strap to pass through.

23. The device according to claim 22, wherein the roller is arranged within the cutout.

24. The device according to claim 22, wherein the cutout is closed all around.

25. The device according to claim 21, wherein the roller is rotatable about an axle pin welded to the metal core.

Description

[0015] The invention is explained further in the following text on the basis of an exemplary embodiment and the accompanying drawings which relate to this exemplary embodiment and in which:

[0016] FIG. 1 shows a device according to the invention in different working positions,

[0017] FIG. 2 shows a side view of a connecting piece used in the device in FIG. 1, and

[0018] FIG. 3 shows a plan view of the connecting piece in FIG. 2.

[0019] A device for transmitting a restraining force comprises a strap 1 and an element 2 via which the strap 1 is connectable to a tension cord 4 that exerts the restraining force along arrow 3. The tension cord 4 can be a constituent part of a restraining device (not shown), as is disclosed for example in the abovementioned application.

[0020] In the example shown, the strap 1 consists of a firm fabric made of plastics threads and has a width of 5 cm. As a result of overlapping ends being sewn together, the strap 1 is closed nondetachably to form a ring.

[0021] As can be seen in FIGS. 2 and 3, the connecting element 2 is configured substantially in a plate-like manner with a cutout 5 in the form of a rectangular eye opening for the strap 1 to pass through and a circular eye opening 6 for coupling the tension cord 4. A roller 7 mounted on an axle pin 8 so as to be able to rotate projects into the rectangular eye opening 5, the length of said roller 7 corresponding approximately to the width of the strap 1 in the example shown.

[0022] In the example shown, the connecting element 2 has a sheet steel core 9, illustrated by dashed lines, onto which a plastics coating is injection-molded. While the sheet steel core 9 is set back with respect to the outer plate rim and the edge of the rectangular eye opening, it projects right up to the circular eye opening 6.

[0023] The axle pin 8 is welded at its ends to the sheet steel core 9. As can be seen in FIG. 3, the plastics coating has a thickened portion 10 in these connecting regions.

[0024] In order to use the device, a training runner, for example, puts the strap 1 around their body 11 and couples the connecting piece 2, which is connected to the strap captively in a form-fitting manner in the example shown, for example with the aid of a snap hook 12 to the cord 4 of the restraining device. As a result of a tensile force exerted constantly along arrow 3 by the restraining device, the strap 1 rests frictionally against the body 11 without sliding down and the connecting element 2 is kept at a distance from the body 11.

[0025] During their running movement, the runner has to constantly overcome a restraining force, with the result that the achievable training effect can be enhanced. As FIG. 1b shows, the device allows a rotation of the body 11 along arrow 13 with a restraining load applied, wherein the roller 7 of the connecting piece 2 rolls in the strap circumferential direction along arrow 14 over the strap inner side.
