Abstract

The invention relates to a training device (1) for training the human body having the features mentioned in claim 1 and a training device having the features mentioned in the independent claim 12.

Description

The invention relates to a training device for training the human body, in particular the back.

BACKGROUND OF THE INVENTION

A wide variety of training devices for training the back muscles are known from the state of the art. Such devices are also referred to as "back trainers." Back trainers, to which reference is made below, comprise a frame with a hip support and calf supports. They allow a user to lean forward and, from this position, move the upper body up and down. The user's hips rest on the hip support, and the legs are anchored to the calf supports. While such back trainers allow training of the back muscles, they offer no other training functions and, in particular, do not allow stretching of the back or relieving strain on the spine.

A generic back trainer is from the DE 299 12 429 U1 Other training devices for training the back are available in the DE 10 2015 113 113 A1 , the WO 2015 / 107 458 A1 , the JP 3 174 189 U as well as the DE 60 2004 007 396 T2 revealed.

OBJECT OF THE INVENTION

It is an object of the present invention to provide a back trainer which enables the user to stretch and relieve the back in addition to training the back muscles.

This object is achieved according to the invention by the features specified in independent claims 1 and 12. Further embodiments of the invention emerge from the subclaims.

The following describes two models of back trainers with a cantilever arm, which have the same basic structure but differ in the type of their cantilever arm.

Model 1

• • ein Gestell mit Füßen;
• • eine Hüftstütze und
• • Wadenstützen.

According to the invention, a training device for training the human body and in particular the back muscles is proposed, which enables a user to place himself in a forward-leaning position and from this position to bend and stretch the upper body, wherein the training device comprises at least the following components:

• • a frame with feet;
• • a hip support and
• • Calf supports.

The training device according to the invention also has a cantilever arm that is pivotally mounted on the frame and has at least one handle. The cantilever arm is designed to run longitudinally, protrude forward from the frame, and is held and pivoted by the user as they move their upper body up and down. This applies forces to the user's upper body that stretch or extend the back.

The pivot axis of the boom arm is preferably a horizontal axis that runs transversely to the back trainer.

The at least one handle is preferably arranged in the region of the head or longitudinally in front of the head of the user.

In a preferred embodiment of the invention, a chest support is arranged on the boom arm. The handle is preferably positioned further away from the pivot axis of the boom arm than the chest support.

The extension arm preferably extends below the upper body or next to the upper body of a user in the longitudinal direction of the back trainer.

In a special embodiment, the boom arm can have arm pads to support the upper arms and/or the forearms.

According to a preferred embodiment of the invention, the cantilever arm is mounted on the frame in the area of the hip support. The mounting point or pivot axis of the cantilever arm is preferably located at a height of 50 cm to 110 cm above the floor.

In another variant of the back trainer, the extension arm is height-adjustable. The position of the hip support is preferably also adjustable. Two separate adjustment mechanisms can be provided for the height adjustment of the extension arm and the hip support. In a preferred embodiment of the invention, only a single adjustment mechanism is provided for both parts. The extension arm can, for example, be mounted on the adjustment mechanism of the hip support, so that both elements can be adjusted in height together.

The length of the entire boom arm, including any parts mounted thereon, is preferably at least 50 cm and in particular between 70 cm and 150 cm.

The boom arm is preferably designed to be length-adjustable. For this purpose, a conventional telescopic mechanism can be provided, for example.

According to a preferred embodiment of the invention, the distance of the chest support and/or the distance of the handlebar is adjustable relative to the pivot axis of the extension arm. For this purpose, the back trainer can again comprise separate adjustment mechanisms or a common adjustment mechanism for both elements.

Model 2

• • ein Gestell mit Füßen;
• • eine Hüftstütze und
• • Wadenstützen.

The present invention also relates to a training device for training the human body, in particular the back muscles, which enables a user to place himself in a forward-leaning position and from this position to bend and stretch the upper body, comprising:

• • a frame with feet;
• • a hip support and
• • Calf supports.

The training device according to the invention also comprises a boom arm mounted on the frame with several handles that are arranged longitudinally at different distances from the frame or mounting point of the boom arm.

The handles are preferably located longitudinally in front of the user's head. They are preferably positioned so far forward that the user can only reach them with essentially straight arms.

The boom arm can be rigidly connected to the frame, but it can also be pivoted.

In the second model of the back trainer described here, the extension arm is preferably mounted on the frame near the feet, just above the floor. The mounting point or pivot axis is preferably located at a height of 0 cm to 50 cm above the floor.

According to a preferred embodiment of the invention, the handles are arranged in pairs on the boom arm, with a first pair of handles being arranged further forward in the longitudinal direction and a second pair of handles being arranged further back.

A first pair of handles can also be arranged higher above the ground in the vertical direction than a second pair of handles. According to a preferred embodiment of the invention, the higher first pair of handles is preferably arranged further forward (farther away from the user) and the lower second pair of handles is arranged further back (closer to the user).

Technical features of the two models can be combined at any time if possible.
