Definitions

  • the present invention relates to a dismountable gymnastic device of the type of a horizontal bar.
  • the plug pin of the bow of the horizontal bar is merely vertically to be inserted at a preferred point of a room ceiling or the like by sliding into a holding part.
  • the holding part and the plug pin enter then, caused by the advantageous design.
  • Limited is the downward movement of the plug pin, by the bayonet connection yielding recesses extending in upward direction.
  • the own weight of.the bow of the horizontal bar retains the latter in its use position.
  • the bayonet closure connection stabilizes itself such that an automatic release thereof is impossible.
  • the release of the bayonet closure connection can take place only upon unloaded horizontal bar bow, which is then to be moved into the holding part in vertical direction and then performs a return rotation in the amount of the part angle. Thereafter the plug pin is removable from the holding part.
  • This prescribed simple coordination as dismounting brings about the advantage, that the gymnastic device is used more often. Due to the bow of the horizontal bar secured at the ceiling of the room. gymnastic exercises considering holding damages can be performed. Depending upon the length of the plug pin the height of the horizontally disposed rod of the bow of the horizontal bar can be determined, so that also children can perform on the latter some exercises.
  • the bayonet slots in the plug pin on the one hand and the bayonet closurepin crossing the bearing bore of a filling member disposed in the holding part housing, on the other hand, realize a simple structure of the gymnastic device of the present invention and thereby low production costs.
  • the bayonet closure pin in the upper ring of an axial pressure bearing disposed in the half-part housing a rotation of the bow of the horizontal bar can be performed about its axle formed by the plug pin.
  • the pressure bearing can be arranged by example between two rings, of which the lower one is compressible and the upper one is effective as a brake ring such, that upon loading the bow of the horizontal bar, due to the compressed lowering, by a slide axial displacement of the axial pressure bearing the free rotability of the upper ring is not interfered with by the brake ring.
  • the holding part housing is to be secured to a ceiling such, that the possible strains do not lead to a release of the holding part.
  • the holding part housing forms either a screw flange mounted on the ceiling or by wall anchors entering the ceiling or the like.
  • FIG. 1 is an elevation of the gymnastic device secured to the ceiling of a room in accordance with the first embodiment of the present invention
  • FIG. 2 is a top-plan view of the device as disclosed in FIG. 1;
  • FIG. 3 is a longitudinal section of a holding part equipped with a screw flange prior to the insertion of the plug;
  • FIG. 4 is a longitudinal section corresponding with the showing of FIG. 3, however with inserted plug pin;
  • FIG. 5 is a longitudinal section through the holding part housing disclosing a second embodiment with unloaded bow of the horizontal bar;
  • FIG. 6 is the holding part with an axial section of the holding part housing with loading of the bow of the horizontal bar;
  • FIG. 7 is an elevation of the holding part housing constituting an equipment for wall anchors:
  • FIG. 8 is a top plan view of the showing in FIG. 7;
  • FIG. 9 is a top plan view of a holding part housing to be inserted into the ceiling and equipped with wall anchors.
  • FIG. 10 is a top plan view of the showing in FIG. 9.
  • the dismountable gymnastics device has a holding part 2 to be secured to a ceiling l ofa room as well as a triangular bow 3 including a horizontal bar entering with the holding part 2 into a plug connection.
  • the bow 3 is designed such that one arm 4 is disposed horizontally. From the carrying point of the two other arms 5 and 6 extends a vertical plug pin 7 of tubular cross sections.
  • the plug-in pin 7 is equipped with diametrically oppositely disposed bayonet-slots extending from the free end of the plug pin axially to the latter.
  • a cross slot 9 follows in one direction, which cross slot continues into an upwardly directed bayonet closure escape recess 10.
  • the holding part housing 11 in accordance with the first embodiment, following FIGS. 1 to 4, carries a filling piece 12 consisting preferably of polyamide.
  • the latter is adjusted to the step-shaped arrangement of the holding part housing 11, such, that the filling piece 12 supports itself with its shoulder 12' on the step 11' of the housing II.
  • a bayonet pin 14 crossing its bearing bore 13.
  • the bearing bore 13 is flush with a bottom side opening 15 of the holding part housing 11 and is adjusted as to its diameter to about the plug pin 7.
  • the bow 3 of the horizontal bar is coordinated to the holding part 2 as follows:
  • the plug pin 7 is at first inserted into the bearing bore 13 of the filling piece 12 such. that the bayonet closure pin 14 can enter'into the bayonet slots 8.
  • the insert movement of the plug pin 7 is limited, if the bayonet closure pin 14 abuts the end edge 8' of the slots 8. Now the plug pin 7 can be rotated, whereby it enters into the cross slots 9. They limit the rotary movement.
  • the bayonet closure pin 14 grips into the upwardly directed bayonet closure escape slots 10 of the plug pin 7, the end edges 10' of which form an abutment for the downward movement of the plug pin 7, (see FIG. 4).
  • the bow of the horizontal bar can be turned into the desired plane.
  • the holding part housing in accordance with FIGS. 5 and 6 is designed in similar manner. Yet, in its inner side an axial pressure bearing is provided.
  • the lower ring 21 of this pressure bearing 20 supports itself on a compressible ring 22, while a brake ring 24 steps against the upper ring 23 ofthe pressure bearing 20. All rings disposed on top of each other have an opening corresponding with the cross section of the plug pin 7.
  • FIGS. 7 and 8 show a holding part housing 11 corresponding with the previously described embodiment, however, with the difference that for its securing wall anchors 27 are provided which originate in equal angular distribution on the periphery of the housing. Then the holding part housing 11 is covered on the upper side by a cap 28. For the purpose ofa good holding are the ends 27' of the wall anchor 27 form sprayed apart.
  • the holding part has a tubular housing 28, the opening 29 of which is crossed by the bayonet closure 14. From the jacket face of the housing 28 extend likewise wall anchors 27, so that the such formed housing could be inserted for its securing into a ceiling.
  • a dismountable gymnastic device formed as a horizontal bar, comprising a bow including a horizontal bar,
  • said bayonet-closure connection including escape recesses extending in upward direction
  • an axial-pressure bearing disposed in said housing and including an upper ring having an opening
  • a dismountable gymnastic device formed as a horizontal bar, comprising a bow including a horizontal bar.
  • said bayonet-closure connection including escape recesses extending in upward direction a bayonet-closure pin
  • said holding means including,
  • a braking ring rigidly mounted in saidhousing.
