Description

chair

The invention relates to a chair according to the preamble of patent claim 1.

A chair of the type mentioned is known from the document DE 90 11 246 Ul. This chair consists of a seat and a connected to the seat and pivotable about a pivot axis abutment element, which in a first pivot position as a backrest for a seated on the seat user and in a second pivot position as a support surface for a standing on the support surface user is designed usable. In this chair, the seat for the realization of the two pivot positions is divided centrally or slotted formed (see in particular protection claim 1 and Figure 3 in DE 90 11 246 Ul).

The invention has for its object to improve a chair of the type mentioned. In particular, a chair is to be created in which the two said pivotal positions are also feasible, but without the seat must be made slotted.

This object is achieved with a chair of the type mentioned by the features listed in the characterizing part of patent claim 1.

According to the invention, it is thus provided that the pivot axis of the abutment element is arranged above the seat surface. In other words, the solution according to the invention is characterized in particular by the fact that the pivot axis is no longer disposed below the seat and thus a division of the seat is unnecessary.

Other advantageous developments emerge from the dependent claims.

For the sake of completeness, reference is made to the more distant document DE 10 2013 110 674 B3, from which a chair with a pivotable backrest is also known. In this solution, a spherical therapy seat surface is arranged on the seat side facing away from the backrest, but - as the actual seat - also serves only for (slightly elevated) seats.

The chair according to the invention including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of a preferred embodiment.

As can be seen in particular in Figure 1, the chair according to the invention comprises a seat 1 and a connected to the seat 1 and pivotable about a pivot axis 2 abutment element 3, in a first pivot position as a backrest for a sitting on the seat 1 user and in a second pivot position is designed to be useful as a support surface for a user standing on the support surface in standing position.

Essential for the chair according to the invention is now that the pivot axis 2 of the abutment member 3 is disposed above the seat 1.

It is particularly preferably arranged on both sides of the seat 1 each one of the seat 1 at least to the pivot axis 2 reaching support element 4. In addition, it is particularly preferred that on both sides of the seat 1 each have an armrest 5 is arranged. Each armrest 5 is preferably arranged in each case pivotally on a seat surface facing away from the end of the support element 4.

Furthermore, it is particularly preferably provided that the abutment element 3 is arranged between carrier element facing away from the ends of the two armrests 5, in particular that the abutment element 3 about a horizontal axis of rotation. 6 is rotatably mounted between the two armrests 5 and, preferably, that the rotation axis 6 is arranged in each pivot position above the pivot axis 2.

More precisely, it is therefore preferable that the seat 1 is connected on two opposite sides, each with a Trägerlement 4, each having a pivot axis 2 at its seat surface facing away from the end. At each of the support elements 4 is an armrest 5, pivotally mounted about the pivot axis 2, attached. Furthermore, an abutment element 3 rotatable about an axis of rotation 6 is mounted between the two armrests, which can optionally serve as a backrest for a seated user or as a support surface for a standing user, depending on the pivoting position of the armrests 5 and the rotational position of the abutment element 3 The axis of rotation 6 is preferably designed to extend parallel to the pivot axis 2.

More specifically, in a particularly preferred embodiment of the chair according to the invention is provided that in a first configuration of the chair, which supports the regular sitting position of a user, the support elements 4 are carried out starting from the seat 1 vertically upwards to this, that the armrests 5 are again formed at a 90 ° angle to the support elements 4 and approximately parallel to the seat surface 1 and that the abutment element 3 is formed approximately at a 90 ° angle to the armrests 5.

In general, it is preferably provided that the seat surface 1 in the first pivoting position of the abutment element 3 has a front edge 1.1 facing away from the bearing element and an abutment element. element-facing trailing edge 1.2 and also that the pivot axis 2 seen in vertical projection or in orthogonal projection on the seat 1 closer to the front edge 1.1 is arranged as at the trailing edge 1.2.

In addition, it is preferably provided that each armrest 5 is formed from an angled flat material with a constant thickness, which is preferably provided with a padding surface 5.1. Similarly, the seat 1 can be formed from a pad 1.3 and a pad 1.3 receiving base element 1.4, wherein preferably the base member 1.4 and the two support members 4 are integrally formed and optionally the base member 1.4 and the two support members 4 of a flat material with a constant thickness are formed. Furthermore, the pivot axis 2 is preferably formed horizontally by both support member 4 extending and formed the abutment member 3 in a first rotational position as a backrest for a seated on the seat 1 user and in a second rotational position as a support surface for a supportive on the support surface standing user usable , To determine the rotational positions of the abutment member 3 also preferably two stops are provided on the armrests 5 and the abutment member 3. Likewise, two stops may be preferably attached to the armrests 5 and the support elements 4 for fixing the two pivotal positions of the armrests 5. In addition, according to a preferred embodiment of the chair according to the invention, the abutment element 3 is U-shaped, in particular concave on one side and convex on one side opposite this side. With regard to the structure of the chair below the seat 1 is preferably provided that there is a vertical support member 7 and at the lower end of a preferably five-armed base 8 is arranged, at the free ends of the base 8 chair rollers 9 are arranged and that the chair rollers 9 under load a Lowering the base 8 permitting and preferably designed to block. In addition, the foot 8 is preferably formed on the floor side with a coming under load with the floor in contact with stopper element 10. As can be seen, these measures serve that the chair according to the invention can not slip with appropriate load from above and from the side.

The vertical support member 7 may be formed adjustable in height. In addition, the upper part of the chair, from the seat surface 1, on the vertical support member 7, to be rotatable about its longitudinal axis. Also, the upper part of the chair (from the seat 1) - as shown in the figures - preferably designed so that it is resiliently tiltable with respect to the vertical support member 7 (not shown separately) that between seat 1 and vertical support member 7, a mechanism for Tilt adjustment is provided.

According to the invention, the claimed chair according to the above-mentioned general and specific embodiments and features can be preferably configured such that the user is able to take the following positions on or on the chair, among other things (and not limited thereto):

As shown in Figures 1, 3, 5 and 6, the abutment member 3 is in the first pivotal position near the trailing edge 1.2 the seat 1 is positioned. The armrests 5 are then aligned substantially horizontally.

In FIGS. 1 and 3, the abutment element 3 is rotated around its axis of rotation 6 in such a way that its main abutment surface is oriented approximately perpendicular to the seat surface 1 of the chair. The user can thus use the chair according to the invention in this position as a conventional chair, d. H. sit with the buttocks on the seat 1, lean against the main abutment surface with the back and rest with the arms on the armrests 5.

In contrast, in FIGS. 5 and 6, the abutment element 3 is rotated about its axis of rotation 6 in such a way that its main abutment surface is aligned approximately parallel to the seat surface 1. The user can sit in this case with his buttocks on the main abutment surface of the abutment member 3 and thus occupy a higher seat position compared to the seat 1. The user's feet are on the side of the trailing edge 1.2 of the seat 1.

In FIGS. 2 and 4, the abutment element 3 is positioned in the second pivoting position near the front edge 1.1 of the seat surface 1. The armrests 5 are then aligned approximately perpendicular. Depending on how the abutment element 3 is rotated about its axis of rotation 6 in this second pivoting position, the following three possibilities arise:

If the user stands, he can rest with his buttocks on the main abutment surface of the abutment member 3 and sit on this basically standing. When the user places his legs on the seat 1 with his legs so to speak, so that his knees are positioned at the front edge 1.1 and his feet at the rear edge 1.2 of the seat 1, he can rest his arms on the correspondingly rotated main abutment surface of the seat Support abutment element 3.

When the user pushes his legs through the opening defined between seat 1 and abutment element 3 and then sits with his buttocks on the seat 1, so that his feet are positioned on the side of the front edge 1.1 of the seat 1, he can with his arms on the correspondingly rotated main abutment surface of the abutment element 3 are supported.

The chair according to the invention thus works as follows:

For example, if the user of the chair wishes to change from a sitting to a standing position, he folds up the abutment element 3 about the pivot axis 2, turns the chair and can now lean against the abutment element 3 when standing.

In the illustrated embodiment, during this process, the U-shaped abutment element 3 can be rotated about the axis of rotation 6, so that the user is supported by the preferred side of the abutment element 3.

More specifically, the adjustment of the desired sitting or standing position by the user depending on the embodiment of the chair according to the invention by the pivoting of the abutment elements 3 about the pivot axis 2 and / or the rotation of the abutment member 3 about the axis of rotation 6 and / or the rotation of the chair itself, or its upper part (from the seat) about the longitudinal axis of the vertical support member 7 made around.
