Abstract

The knee chair has a seat (12) and a knee tank (14), on the underside of each a bottom support (24, 24 ') is mounted, both of which are interconnected via a yoke bar (16). The yoke bar (16) has on its underside a Bodenaufstandskufe (18), which has a to the two floor supports (24, 24 ') rising rocking curve, the pitching movements of the Jochbalkens (16) allows. The Bodenaufstandskufe (18) of the yoke bar (16) is based in the resting state of the kneeling chair (10) vertically below its center of gravity (S) on the bottom (23), wherein the two floor supports (24, 24 ') a distance (a) from the ground (23), the yaw movements of the Jochbalkens (16) allows.

Description

The invention relates to a kneeling chair with a bench and a knee bench, on the underside of each a floor support is attached, both of which are connected to each other via a yoke bar.

For longer sitting activities, for example at the desk or in front of a screen, not infrequently muscle tensions arise that cause pain or lead to malpractice and must be treated physiotherapeutically. As a precaution, doctors, health insurances and professional associations recommend more frequent breaks and gymnastic exercises.

From the utility models DE 87 10 133.5 . DE 87 14 918.4 and DE 20 2004 012 295 Rocking chairs are known which have two parallel yoke bars, which allow a pitching motion about the Querarchse, but not yaw movements about the longitudinal axis.

In the DE 38 04 399 A1 is an embodiment of a knee stool with a central yoke bar explained, the rocking curvature admittedly allows a pitching motion, the base surface but can be shaped so that a rocking in the lateral direction is possible. For this, however, the base must be provided with a three-dimensional curvature.

Out EP 2 762 039 B1 For example, a chair for relieving back complaints is known, which has a reclining backrest from which extend movable support elements which are to be arranged below the user's armpits.

The invention has for its object to provide a kneeling chair available that can be used in sedentary work and at the same time prevents the above problems at work by being designed so that poor posture can be avoided.

To solve this problem is used according to the invention, a kneeling chair of the initially outlined type, which is characterized in that the yoke bar on its underside has a Bodenaufstandskufe having a rising to the two floor supports rocking curvature, which allows pitching movements of the Jochbalkens, and that the Bodenaufstandskufe the yoke bar in the resting state of the kneeling chair vertically supported under the center of gravity on the ground, the two floor supports have a distance from the ground, which allows yawing movements of the yoke.

With such a knee chair is achieved that the person sitting on it with her knees on the knee tank so supported that it inevitably occupies an upright position in which the spine is approximately vertical and not curved. This is achieved by the person endeavoring to adjust the kneeling chair by the pitching motion around the center of gravity and to hold it in this position, which is essentially unconscious and inevitable.

Due to the additional yaw movements, d. H. Vibrations around the longitudinal axis, the kneeling chair with the person sitting or kneeling on it adjusts itself so that it only supports itself on the nearly punctiform contact surface of the runner of the yoke bar, so that rotational movements about the vertical axis are also possible.

According to a further feature of the invention, the bench and the knee bench are arranged inclined to each other, it is advantageous if the knee tank is adjustably attached to the yoke bar about a horizontal pivot axis, while the bottom support of the seat is fixedly mounted on the yoke bar.

The floor supports and the yoke beam may consist of plates, for example wooden panels, or of permanently connected pipe sections.

Further features and advantages of the invention will become apparent from the claims and from the following description of exemplary embodiments, which are illustrated in the drawing. In this show:

The in the 1 to 6 as well as kneeling chair 15 to 17 shown 10 according to the invention is composed of plates, in particular wood panels; a production of plates of another material, such as plastic, is also possible.

The kneeling chair 10 has a bench 12 and a knee bench fastened in front of it 14 , which are both inclined to each other. Not shown is the possibility of both the seat 12 as well as the knee tank 14 to be provided with a cushion pad. In the example of 7 to 14 are the bench 12 and the knee tank 14 mounted on a frame which is composed of firmly interconnected pipe sections.

The bench 12 is with the knee tank 14 over a yoke bar 16 connected in side view approximately the shape of a J sawed from a flat board or a metal plate ( 15 to 17 ) is milled. The yoke beam 16 has on its underside a Bodenaufstandskufe 18 which, according to the 2 and 15 at rest of the kneeling chair 10 under its focus S in a contact point 20 on the ground 23 supports, so that in 2 drawn vertical connecting line 22 for emphasis S a rotation axis for the knee chair 10 forms.

How the particular 2 and 6 or 15 to 17 show is at the bottom of the seat 12 a plate-shaped floor support 24 attached, which is designed so that they from the yoke beam 16 sticks out on both sides. A similar floor support 24 ' is below the knee tank 14 on both sides of the yoke bar 16 from. The two floor supports 24 . 24 ' have at rest the kneeling chair 10 a distance a of the order of about 1 cm from the ground 23 , so that also yaw movements of the Jochbalkens 16 are possible, ie laterally pivoting movements around the contact point 20 which is in the longitudinal axis of the kneeling chair 10 lies.

The figures further show that the knee tank 14 via a horizontal pivot axis 26 adjustable at the yoke bar 16 is attached. These are the plate-shaped knee tank 14 two parallel cheeks 28 down from the yoke beam 16 and at this by the pivot axis 26 are attached.

In 6 is made visible that the overall focus S ' of the system with the knee-chair 10 sitting person on the vertical connecting line 22 above the center of gravity S of the kneeling chair 10 and above the point of contact 20 of the yoke bar 16 which also causes a circular movement about the vertical axis 22 is possible. In addition, it enforces an upright posture of the person, so that muscle tension in the area of the spine and shoulders are avoided, while the hip circular movements around the vertical axis 22 can perform.

In the embodiments of the 7 to 14 form the ground supports 24 . 24 ' and the yoke bar 16 a frame 30 , which is composed of firmly interconnected pipe sections.

The 16 to 17 show another variant in which vertically below the center of gravity S at the yoke bar 16 a support wheel 32 With horizontal axis of rotation freely rotatable so that it is above the Bodenaufstandskufe 18 protrudes downwards. Below under the jockey wheel are more support wheels 32 ' stored with parallel axes.
