Abstract

In order to exclude the risk of pinching or squeezing body parts when performing strength exercises, a rigid bearing bracket 2 for receiving a stop axis 3 and a swivel axis 4 is arranged on the joint of a force exercise device on an insertion tube, with a stop profile 5 on the swivel axis 4 provided stop 6 is guided, which is rigidly arranged on the pipe to be pivoted. The joint training can be used particularly advantageously in leg curlers.

Description

  • The invention relates to a joint for a power training device, in particular for leg curlers, in which a tube is pivotally mounted on an axis and corresponding stops are arranged to limit the pivoting movement.
  • In the known joints for exercise machines, the stops for limiting the pivoting movement of the bent tube are freely accessible, so that there is a risk of pinching or squeezing.
  • The invention has for its object to form a joint of the type shown so that the strength exercises can be carried out without the risk of pinching or crushing body parts.
  • This object is achieved in that a rigid bearing bracket for receiving a stop axis and a pivot on an insertion tube axis is arranged, a stop provided with stop profiles being guided on the swivel axis, which is rigidly arranged on the pipe to be pivoted, the stop being formed by two stop disks running parallel to one another and the bearing bracket being formed by two bearing bracket disks running parallel to one another .
  • In a preferred embodiment, the stop discs of the stop are guided between the bearing holder discs of the bearing holder. The stop profiles of the stop can be adapted to the circumference of the stop axis and lie against it. Expediently, two stop profiles are arranged at a distance from one another on each stop disc of the stop, the pivoting range of the stop being limited by the distance between the stop profiles.
  • Further expedient refinements of the invention are set out in the remaining claims.
  • The joint design according to the invention can advantageously be used in leg curlers where the stop alternately strikes the stop axis. However, it can also be used with other strength training devices. The risk of being pinched or crushed is eliminated by the arrangement of the protective cap and the clip-on cap.
  • An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
    • Fig. 1 shows a longitudinal section through a joint and
    • 2 shows a section along line AB of FIG. 1st
  • A bearing bracket 2 in the form of two bearing bracket disks running parallel to one another at a distance is rigidly arranged on an insertion tube 1. These bearing bracket disks run at right angles to the insertion tube 1 and serve to accommodate a stop axis 3 and a pivot axis 4, both axes 3, 4 being fixedly mounted. On the pivot axis 4, a stop 6 provided with stop profiles 5 is guided, which in turn is rigidly arranged on a leg curler tube 7 to be pivoted.
  • As can be seen from FIG. 2, the stop 6 is formed by two stop disks which run parallel and at a distance from one another and are guided between the bearing bracket disks of the bearing bracket 2. Each stop disk of the stop 6 has two stop profiles 5 which are arranged at a distance from one another. The pivoting range of the stop 6 and thus the pivoting range of the leg curler tube 7 is determined by this spacing of the stop profiles 5.
  • The stop 6 and the stop axis 3 are covered by a protective ring 8 which is attached to the leg curler tube 7. The protective ring 8 and the end face of the insertion tube 1 are covered by an outer protective cap 9.
  • The stop axis 3 and the pivot axis 4 are passed through the bearing bracket 2 and the front faces of the axes 3, 4, which are visible from the outside, are covered by a clip-on cap 10.
  • Reference number:
    • 1 insertion tube
    • 2 bearing bracket
    • 3 stop axis
    • 4 swivel axis
    • 5 stop profiling
    • 6 stop
    • 7 pipe
    • 8 guard ring
    • 9 outer protective cap
    • 10 cap
