Definitions

  • the invention relates to an ingot with bracing device, in which an adjusting device is provided between the two ingot supports of each of the two pairs of ingot supports and in which two rope devices are provided on the side next to each pair of ingot supports, one end of which is fastened to the ingot support and the other end of which is attacked on Floor is provided, with a compensating device being provided between one end of one of the cable devices and the floor.
  • the gymnastics bar according to the invention is solving this problem, characterized in that the compensating device is a tension spring device with a compression spring element having a progressive spring characteristic.
  • a tension spring element is not used because this proves to be too long, whereas a compression spring element, despite the relatively large desired spring travel, is quite short and correspondingly lightweight.
  • a bar spacing change can be effected in a greatly simplified manner by actuating only the two adjusting devices.
  • the creation of a spring element with a linear, constant spring characteristic is avoided.
  • the progressive spring characteristic normally given for a compression spring element does not prove to be disruptive, since experience has shown that the athletes, with a greater distance between the spars, want the tension to increase in tension. If the bar is loaded up to its elastic limit during gymnastics, then it does not become jerky hard because of the tension spring device, but is "softly" limited.
  • tension spring device is fixed or anchored at one end directly to the floor. A piece of rope between the tension spring device and the bottom is thus avoided, so that any swinging of the relatively weighty tension spring device is suppressed.
  • the compression spring element is a block made of elastically compressible plastic. This compression spring element is relatively light and builds relatively short.
  • the compression spring element block is provided with circumferential grooves.
  • the progressivity of the spring characteristic of the spring element is reduced by these groove-like structures. With a growing number of grooves and a growing groove cross-section, the progressiveness of the spring characteristic decreases. The spring characteristic is therefore adjustable.
  • the compression spring element is designed for a spring travel of 8 to 15 cm, preferably approximately 10 cm. With this design, the compression spring element is already somewhat compressed with the smallest spar spacing, i.e. under tension and the compression spring element is maximally compressed with the greatest spar spacing.
  • the gym bar according to the drawing has two horizontal bars (1), each of which is supported by two bar supports (2), only one of the two bar supports of each bar being shown in FIG. 1.
  • the bar supports (2) are each articulated at the bottom on the floor (3) and are provided with adjustment devices (4) at the top, near the upper end of the lower bar supports.
  • An adjusting device is provided between the two bar supports (2) of a pair of bar supports, which represents a spacer, the length of which can be changed by screws.
  • Each pair of bar supports is assigned two pulling cable devices (5) which engage at the upper ends of the bar supports (2), form an angle with one another and run down to the floor (3).
  • Each pull rope device has a rope, the two ends of which are fastened to the two bar supports and which form two pull rope sections (6) which form an angle with one another and which merge into one another in the case of a compensating device (7) designed as a roller.
  • One compensation device is anchored to the floor by means of a piece of rope (8).
  • the other compensation device is located at one end of a piece of rope (9), the other end of which acts on a tension spring device (10) which is articulated on the floor (3).
  • the tension spring device (10) comprises a sleeve (11) which receives a block-like, elongate, compression spring element (12) which is round in cross section and is closed with a screwed-on cap (13).
  • the cap (13) is articulated on the base (3) by means of sleeves (14).
  • the compression spring element (12) is provided with circumferential grooves (17) which are identical to one another and which may be at the same distance from one another.
  • the block-like compression spring element (12) consists, for example, of rubber or a suitable plastic.
  • the compression spring element consists, for example, of a cellular polyurethane elastomer, which is a slightly foamed product with a density of 200 to 650 kg / m3. It results from the reaction of polyhydroxyl components (Polyester or polyether) with diisocyanates and subsequent reaction with a "crosslinker".
  • polyhydroxyl components Polyhydroxyl components
  • NDI 1,5-naphthylene diisocyanate
  • the progressivity of the spring characteristic can be linear or increasing.
  • the spring device is pretensioned with a narrow beam spacing of 50 to 55 cm with a spring travel of 3 to 4 cm and exerts a force of 980 to 1960 N (100 to 200 kp). If the widest beam spacing is set from 105 to 110 cm, there is a spring travel of 10 to 12 cm with a force of 3920 to 5880 N (400 kp to 600 kp).
