"Gymnastics equipment, especially parallel bars"

The invention relates to gymnastics equipment, in particular a bar with a cross-sleeper Frame and with feet arranged on the latter as well as the floor which can be supported, in particular as swivel castors trained rolling elements.

In order to be able to transport an ingot relatively simply and easily, it is known between the ends of the sleepers downwardly protruding rigid feet to provide rollers which, if necessary, go down over the The base level of the feet can be adjusted. For this purpose, it is also known that the rollers are coaxial to be arranged height-adjustable to the column sleeves, where ^ ei eccentric actuators are provided.

However, this has the disadvantage that the roll holder extending into the column sleeves of the frame the adjustment stroke of the columns supporting the spars is reduced.

In addition, this known roller arrangement allows a total of only four rollers, which, however, result in high floor loads result, which as a result of the relatively high bar

weight to permanent deformation of the floor being able to lead.

In a further known from the operational practice bars are in the open channel below the Trough-shaped profiled cross sleepers several one behind the other in the longitudinal extent of the cross sleepers arranged rollers are provided, which are mounted in groups on a frame which is in the cross sleepers is held adjustable in height. This can reduce the floor load per unit area can be reduced, but this roller arrangement is relatively complicated, laborious and expensive.

The object of the invention is now to provide a piece of gymnastics equipment, in particular a bar as described in the preamble of the claim 1 specified type to improve so that while maintaining the prior art already achieved Advantage, namely the relatively lighter one. The gymnastics equipment can be transported with at least the same level of stability with simpler means and measures than previously lower floor loads from the rollers are attainable.

The solution to this problem is characterized in that the rolling elements over the cross sleeper underside are arranged constantly protruding downward, and that the feet protrude on the one hand downward beyond the base plane of the rolling elements and on the other hand, can be withdrawn upwards beyond the aforementioned base plane and can be releasably locked in the two end positions are trained.

With these measures you are now in the design, the number and the arrangement of the rolling elements almost completely independent of each other as well as relative to the frame.

It is now also possible depending on the weight of the gymnastics device and / or depending on the load capacity of the floor to arrange further rolling elements afterwards.

In addition, compared to the known gymnastics apparatus with roles combined into groups, there is no production and assembly of their liftable and lowerable chassis.

Witte 8224/83

It is beneficial in the sense of the task if on the end parts of the cross sleepers are at least approximately vertically directed straight guides, by means of which the feet are mounted so that they can be adjusted in height and that they are fixed to the frame as actuators, to the adjustment direction of the feet transverse axes limited rotatable and directly on the feet attacking eccentrics are provided.

B (? Each foot is preferably an adjusting device assigned.

For releasable locking of the foot end positions, it is advantageous if the feet over one of the Eccentric shaft striving and in the foot end positions to be placed on the frame lever, in particular over an eccentric handle can be locked.

A possibly preferred, possibly extensively applicable Design for releasably locking the feet in their end positions is that the Eccentrics are each arranged so that they can be rotated by more than 180 ° that they are in the upper foot end position

are rotatable and can be applied directly to stops in a rotation-limiting manner.

The foot brackets can be molded onto the cross sleepers.

A preferred one that is particularly favorable in terms of production technology Design for a gymnastics equipment frame with rib-shaped profiled cross-ties over its entire length is characterized in that in each downwardly open gutter end part of the cross sleepers a prefabricated, adapted to the channel profile Foot bracket is used and connected to the crossbar, preferably such that each foot bracket an in particular centrally arranged vertically directed, in particular cylindrical Has a bore into which a foot profiled according to the bore is inserted axially adjustable, also the foot bracket of one of the aforementioned Crossing the bore and, in particular, the transverse bore which is the same as that of the longitudinal extension of the cross-sleeper is penetrated, in which an externally actuatable shaft is mounted and the latter one The groove of the foot, which is open at the top, extends through ur <d in the area

the channel has an eccentric which can be placed against one of the channel flanks of the base in a rotationally limiting manner, and that the foot is attached to the eccentric.

Further advantageous designs of the foot brackets and feet that are conducive to the task are shown in the claims 9 to 12 disclosed.

An exemplary embodiment of the invention is shown in the drawings and is described below described in more detail.

In the center of each foot holder 4 is a vertical, cylindrical, which forms a straight line Bore 7 arranged, which is designed as a through hole.

In this bore 7 a cylindrical foot 8 is inserted axially adjustable with Schiebeeitz. Furthermore, the foot holder is of a horizontal transverse bore that crosses the bore 8 in the middle and is aligned with the longitudinal extension of the cross sleeper 9 penetrated into which a shaft 10 is inserted.

The shaft 10 extends through a groove 11 of the foot 8, which is open at the top, and has an integrally formed, smaller-diameter eccentric 12, which is used to limit rotation the shaft 10 by more than 180 ° and each slightly above the top and bottom dead center a flank part 13 of the channel projecting into the channel 11 can be placed.

This flank part 13 is slightly smaller in the axial direction than the eccentric 12, so that the dem Eccentric 12 facing end faces of the shaft 10 with

Can apply movement play to the flank part 13 and set the shaft 10 in the axial direction.

In addition, a diametrical and right-angled to the shaft 10 in the upper end of the foot directed groove 14, in which a rod 15 supported on the eccentric 12 is inserted, the end parts in the groove 14 by rivet-like inwardly bent parts 16 of the Groove flanks are set. In the outer end face of the shaft 10, an internal polygonal hole 17 is arranged in which to Actuation of the shaft 10 and thus of the foot 8, a handle 18 can be inserted rotatably and detachably, It is also possible to non-detachably fasten the handle 18 to the shaft, for example to mold it on.

The foot bracket 4 and the feet 8 are made of light metal to save weight, while the Shaft 10 with molded eccentric 12 made of steel.

In addition, the foot bracket 4 has open on the underside, the screws and their nuts receiving and that The dead weight of the foot brackets continues to decrease

To reduce the floor surface pressure, it is also possible, at the lower end part of each foot 8 to arrange a footplate with a larger area than the cross section of the foot 8, which is in the cross sleeper 2 withdrawn foot 8 engages in corresponding recesses of the foot bracket so that the base plate, not shown, is also flush with the underside of the cross sleeper 2.

The rod 15 is preferably supported by frictional engagement on the eccentric 12 to prevent an unintentional To complicate rotation of the shaft.

The invention can advantageously also be used, for example, in transportable balance beams.

In the grooves of the sleepers 2 are between the

Feet 8 a plurality of longitudinal rollers 19 directly supported on the cross sleepers are provided opposite the feet 8 retracted into the cross sleepers 2 protrude.
