Abstract

System constituted of a trampoline and a handle device, characterized in that the handle device can be fastened so as to be removed separately.

Description

Trampoline with removable grab handle

The invention relates to an arrangement of a

Trampoline and a handle device, which is completely disassembled.

Trampolines are out in the sports and leisure area

public prior use known. It is usually a device consisting of a frame on stilts, on which a jumping mat is resiliently mounted. In addition to use for acrobatic or athletic exercises and demonstrations on large, several meters in diameter

Trampolines have also established large trampolines as playground equipment for the garden; In addition, there are also numerous smaller variants (mini trampolines), which are suitable as a training device for home use.

It is also previously known to provide such a mini-trampoline with a handle device to provide the user with the use of the trampoline stop. These

Handle device can be designed in the form of a bracket, which projects beyond the edge or part of the jump surface. Embodiments are also known in which a single vertical rod is attached to the frame at the upper end of a horizontal handle is attached, which is designed as a straight T-piece or bent similar to a bicycle handlebar. The handlebar may in any case be slightly angled towards the surface of the jump in order to be more easily accessible when using the trampoline.

However, all of these handle variants have the problem that the attachment for the handle must necessarily be very stable to the tensile force occurring when used by the Endure user. Especially in the case of grip rods, which consist of a single pipe element, the burden of the occurring leverage at the attachment point is particularly large. Therefore, fasteners are known in which the handle bar or the handle bars or their recordings are firmly connected to the frame and / or the stilts, for example by welding. Although the handle can usually still be adjusted and disassembled to a limited extent, it always remains even after disassembly

Pipe intake or a junction back, which represents a risk of injury when you descend from the trampoline or even in case of accidental missteps and kicks, because body parts, especially toes, can get caught.

Object of the present invention is to provide a training device of the type mentioned, which offers full functionality and structural integrity with mounted handle, but also with disassembled handle without

Restrictions in functionality and product safety can be used.

First, some terms used in the invention are explained.

The term trampoline means in the context of this invention is always a mini-trampoline. It is a construction consisting of several stilts, on which a round or polygonal frame is mounted, on which, for example, coil springs, elastics or latex strands as resilient

Component used to attach a no or only slightly elastic jump cloth. Such trampolines are intended for home use and can be used in both

Outdoor as well as inside the building and in living rooms with regular ceiling height can be used as the bounce increases the cracks of the user only to a limited extent. The The jump surface has a diameter of half to about one and a half meters, the length of the stilts is usually between 20-50cm. The stilts are usually mounted so that they are orthogonal to the ground from the frame. The attachment to the frame or the outer radius of the

Frame ensures optimal stability.

In the context of this invention, moreover, only a trampoline with a handle device is mentioned. These

Handle device may be configured as a bracket, so that a user can grasp the crossbar, alternatively, a handle is possible in which a single rod rises vertically, at the end of which a T-handle or curved handles are approximately in the form of a bicycle handlebar. The grip parts that are intended to attack, can be gummed for a better grip or covered with leather, fabric or foam.

Usually, for reasons of product safety, the resilient components are covered with a cushion surface in such a way that, in the event of a misstep or jump, a user does not associate with the foot or individual toes in the suspension

can catch, resulting in uncontrolled falls and

Bone fractures can result.

For the same reason, the present invention proposes a solution to avoid that after disassembly of the

Handle device an open pipe or the like

protrudes. The invention is based on the idea to provide a completely removable mounting option for the handle device, which nevertheless the necessary

Stability offers.

In the context of this invention is provided a

Handle device, preferably in the embodiment by means a single vertical bar with final handle elements to use. However, this is not mandatory, conceivable is also the attachment of a bracket or a multi-part frame construction.

The arrangement according to the invention provides to mount the handle bar in such a way that a hollow tube with a certain diameter is mounted on a first stilt. The hollow tube preferably has one for reasons of stability

Outer diameter of 2.5 - 4 cm and a wall thickness of 0.6 - 1.5 mm, more preferably an outer diameter of 2.5 - 3.2 cm and a wall thickness of 0.6 - 1.1 mm. A round one

Cross-section is preferred here, but it is also the

Use of a square or polygonal tube

conceivable.

Furthermore, the hollow tube has an upper first and a lower second end. The lower second end is characterized in that it is flush with the first stilt on the ground. In this case, the hollow tubes at the lower second end of L-form assume to provide additional pressure stability against shocks from the trampoline central axis away.

Alternatively, the hollow tube can be closed at its lower second end by means of a rubber stopper to protect the soil from damage. In an alternative and equivalent design within the scope of this invention, the hollow tube is designed in several parts, wherein the various parts can be fixed to each other by means of plug connections or fastening means. As attachment for the parts of the hollow tube and the connection described below can be used.

The hollow tube and the first stilt must have at least two suitable devices in order to be reversibly connected to each other. This can be done by means of a

Plug connection done or by means of bolts and split pins, but preferably by means of bores and the connection by means of threaded screws and nuts.

In a preferred embodiment, the hollow tube at the upper first end via a bore with a thread for receiving a locking screw which orthogonal to

Central axis of the hollow tube is screwed.

The vertical handle also has an upper first end and a lower second end. The upper first end serves to receive the handle crossbar or the

Handle cross-catching.

The outer diameter of the vertical handle bar can the

Inner diameter of the hollow tube correspond, so it

completely plugged into this, alternatively, the

Outer diameter of the vertical handlebar but also the

Outer diameter of the hollow tube correspond, with a

Rejuvenation of the outer diameter of the vertical handle bar at the lower second end to the inner diameter of the hollow tube.

The vertical handle bar preferably has a plurality of recesses, hollows or holes, with the

Locking screw in the hollow tube correspond to allow a secure locking at different heights.

In a particularly preferred embodiment, the

Handle bar after the last recess or hole towards the vertical center axis of the trampoline jumping surface

angled to allow easy accessibility of the handle by the user. The angle of inclination is

preferably between 5-45 °, more preferably 5-25 °, more preferably 10-20 °.

The vertical handle bar may be in an alternative

Design also be designed such that the lock in the hollow tube only by means of a simple locking screw always takes place at the same level, but a

Height adjustment mechanism is provided which is adjustable via a further telescopic tube and a further adjusting screw. This alternative height adjustment may be located before the vertex of the angle or behind the vertex of the angle.

The horizontal handle can be screwed on separately

be designed for easier complete disassembly and better stowage.

The hollow tube can be attached to the first stilt either directly

be screwed, but is preferred

Stability reasons, the lock with the aid of a profile piece to ensure vertical torsional stability. The profile piece should preferably extend over a large part of the height of the stilt and on both sides over the entire length have vertical recesses for the stilt and the hollow tube. Also holes must be provided in the profile piece, which correspond to the holes in the first stilt and the hollow tube, which are suitable for receiving the fastening means.

In order to avoid a horizontal twisting of the stilt with the hollow tube, the invention provides that support elements are pulled in the form of cross braces from the first stilt to each clockwise and counterclockwise at least one other stilt. The cross struts are preferably designed as a tube strut, with pierced tabs at the ends. It is provided that these cross struts are fastened at a first end in each case together with the hollow rod to the first stilt and with the respective other end by means of a further fastening element,

preferably a threaded screw to be attached to the adjacent respectively further stilts. To a maximum To achieve torsional stability, it is advantageous to attach the struts with their respective first end to the lowermost bore of the hollow tube and with the respective second end as close as possible to the respective upper end of the respective other stilts, so close to the frame, so that exercise force when not use leads to a deformation over the length of the other stilts.

For the disassembled state of the handle device is further provided to cover or close the holes in the first stilt and in the other stilts by means of plastic or rubber stoppers.

In an inventively designed arrangement of a

Trampolins with GriffVorrichtung it is then possible to achieve the vertical and horizontal stabilization of the handle device with a simple assembly by means of the hollow tube and the profile piece and by means of at least two further cross braces.

Alternatively, the trampoline can also without handle bar without functional limitation and without sacrificing the

Product safety can be used because in the disassembled state only (reversible lockable) holes remain in the stilts.
