Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair having an outer frame, a seat portion and a backrest portion, the seat portion being in a comfortable or reclining position from a basic position in which the seat portion does not project from the front edge of the outer frame at all or only slightly. In this comfortable or reclining position, the front end of the seat part projects from the front edge of the outer frame and the backrest part pivots to the rear end of the seat part at its lower end towards the rear end of the seat part. Therefore, when the seat part is displaced from the basic position to the comfortable or reclining position, the back part can also be displaced together, the back part being
The present invention relates to a device that can be forcibly displaced from a relatively steeply raised basic position to a comfortable or reclining position that is gently inclined with respect to the basic position.

[0002]

Such chairs are known in the prior art. To operate the chair to move it from the basic position to the comfortable or reclining position, the user moves the seat part forward from the basic position over the front edge of the outer frame by exerting a pressing force on the seat part with the hips. As a result, at the same time, the backrest portion is entrained so that the steep sitting position is shifted to a slightly inclined comfortable or reclining position. The backrest part is pivoted at its lower end to the rear end of the seat part, so that it can follow the movement of the seat part and can be swung around its pivot range. Furthermore, in the solutions known in the prior art, the backrest part is pivoted on the outer frame at approximately the center of its longitudinal dimension, so that it can be swung around this joint axis. The return movement from the comfortable or reclining position is likewise done by loading the seat part by the user's hips and displacing it towards the rear end of the outer frame, thereby simultaneously raising the back part.

The drawback of such a solution is the inability to install a chair close to the wall. This is because the rocking of the back part is no longer possible and thus the entire displacement movement of the chair can no longer act. When rocking the backrest from a steep sitting position to a gentle comfort or reclining position on the slope, the upper end of the backrest moves on an arc around the swing axis of the backrest, so the upper end of the backrest is In the comfortable or reclining position, it projects significantly from the rear end of the outer frame. As a result, such a chair can only be installed far away from walls and the like.

[0004]

Starting from this prior art, it is an object to provide a chair of the type mentioned at the beginning, which allows an otherwise wall-mounted installation with the same operating process and operating method. Is the basis of the present invention.

[0005]

In order to solve this problem, according to the present invention, the backrest portion has, in the second pivot range, a first straight line whose lower end is fixedly attached to the outer frame. It is forcibly guided by the guidance department.

With this construction, on the one hand, during the displacement of the seat part from the basic position to the comfortable or reclining position, the backrest part is entrained and thus its seat-side end is displaced into the front region of the outer frame. On the other hand, the second pivot range forcibly guided by the straight guide part causes the backrest to swing from a steep base position to a comfortable or reclining position with a gentle slope. Simultaneous swinging and moving movements allow the upper end of the backrest part to move slightly beyond the rear end of the outer frame in any case, so that it can be installed close to the wall of the chair without impairing its function.

It is preferably provided that the first linear guide consists of a rod or a tube.

Particularly preferably, the first linear guide comprises a rail of irregular cross section, in which a sliding part is guided, the sliding part carrying a joint pin forming a pivoting range. Are being considered as if.

In order to further improve the comfort or the comfort in the reclining position, the first straight guide part extends obliquely with respect to the horizontal plane so as to slightly descend toward the front end of the outer frame, Is being considered.

Particularly preferably, it is provided that the irregular cross-section rail is constructed as a C-shaped irregular cross-section.

A preferred detailed solution is to mount a first coupling pin on the rear end of the seat part, around which the fitting part at the lower end of the backrest part can be swung, The metal fitting portion is movably held along the first linear guide portion, or is swingable around a second joint pin pivotally attached to the outer frame at the other end, and the second joint is provided. The pin is provided closer to the rear end of the outer frame than the first joint pin.

Here, the mutual spacing of the two coupling pins is taken into account such that it is equal to or greater than the thickness of the backrest part.

More preferably, the rear end of the seat portion is pivotally attached to a second linear guide fixedly held by the outer frame, or the rear end of the seat portion has the other end of the outer frame. Pivotally attached to the second connecting piece, which is pivotally attached, such that the second connecting piece is oriented in the basic position substantially vertically or rearwardly with an inclination towards the backrest part. There is.

More preferably, a third linear guide portion is mounted below the seat portion and extends to near the front end of the seat portion,
It is guided by a guide portion attached to the front end of the outer frame.

It is possible here for the second and / or the third linear guide to consist of a tube or a rod.

Preferably, however, the second and / or the third linear guides consist of rails of irregular cross section, in which the sliding part is guided or which rail is guided in the sliding part. So, it is considered.

In order to improve the comfort of the user, it is taken into account that the second linear guide is directed slightly elevated towards the front end of the outer frame.

For the same reason, the third linear guide is taken into account such that it is oriented slightly elevated towards the front end of the seat part.

An advantageous and purposeful development is that the joint pin passes through the sliding part of the second rail of irregular cross-section and a fitting part which projects below the rear end of the seat part is pivotally attached to this joint pin. There is a point.

It is also considered that the joint pin passes through the sliding portion of the third irregular cross-section rail, and the metal fitting portion fixedly held by the outer frame is pivotally attached to the joint pin.

Furthermore, it can be considered that at least one of the linear guides has a terminal stop as a stroke limiting part.

A particularly preferred development is the first of the backrest part.
When the load is placed on the backrest part of the linear guide part of, the pivoting range is restrained by tightening, and when the load of the backrest part is removed, the pivoting range is movable along the first linear guide part. is there.

With this configuration, the chair can be adjusted only when the user applies a load to the seat by the buttocks and moves the seat forward or backward depending on the desired position of the chair. Can be However, when the user abuts the backrest, undesired adjustment of the chair is not possible, because the applied load causes the part movable along the first linear guide to be clamped in this linear guide. Only when the backrest has been unloaded by the user can the chair be adjusted and operated.

In the claims, even if only one suitable element (straight guide, etc.) is a problem, the present invention provides a plurality of suitable elements each attached to a side wall of the outer frame or to the outer frame. It is considered that it is provided in the raised portion or the back portion and the seat portion.

Embodiments of the invention are shown in the drawings and will be explained in more detail below.

The seat part 4 is displaceable from the basic position shown in FIG. 1 to the comfortable position according to FIG. 2 or the reclining position according to FIG. In the basic position, the seat part 4 projects completely or slightly from the front edge of the outer frame 2. At the reclining position, the front end of the seat portion 4 projects from the front edge of the outer frame 2. The backrest part 3 is pivotally attached at its lower end towards the rear end of the seat part 3 to the rear end of the seat part 4 (joint point 5), so that the seat part 4 moves from the basic position to the comfortable or reclining position. When displaced, the backrest part 3 is also carried.
At that time, the backrest portion 3 is forcibly displaced from the basic position according to FIG. 1 which is raised relatively steeply to the comfortable or reclining position according to FIG. 2 or FIG. It is more gentle with respect to the position.

In order to ensure that the ends of the backrest part 3 do not project too much in the comfortable or reclining position according to FIG. 2 or 3 than in the basic position according to FIG. 1, the backrest part 3 has a second end at its lower end. The first linear guide portion 7 fixedly attached to the outer frame 2 in the pivotal range of
Have been forcibly guided by.

The first straight guide 7 consists of an irregular cross-section rail which is embodied as a C-shaped irregular cross-section rail. In this rail of irregular cross-section, a sliding part 8 holding a joint pin forming a pivoting area 6 is guided.
The first straight guide portion 7 is inclined with respect to the horizontal plane so as to slightly descend toward the front end of the outer frame 2. A first joint pin is mounted at 5 at the rear end of the seat part 4 and a fitting part 9 at the lower end of the backrest part 3 can be swung around this joint pin. The fitting part 9 is further pivotable about a second joint pin joint pin (pivot area 6), which second joint pin is movably held along the first linear guide 7. There is. The second joint pin 6 is provided closer to the rear end of the outer frame 2 than the first joint pin 5. The mutual spacing of the two coupling pins 5, 6 is slightly larger than the thickness of the backrest part 3.

The rear end of the seat portion 4 is also forcibly guided in a swingable manner by the second linear guide portion 10 fixedly held by the outer frame 2.

A third straight guide portion 11 is mounted below the seat portion 4 and extends close to its front end, and is guided by a guide portion 12 fixedly attached to the front end of the outer frame 2. In the embodiment, the guide portion 12 is fixed to a cross member 13 that joins both side walls of the outer frame 2. A separate cross member 14 is also provided in the rear area of the chair for reinforcement. Outer frame 2
A metal plate 15 is attached to the side wall of the device, and an appropriate element is attached to the metal plate. The second or third linear guide part 10, 11 also comprises an irregular cross-section rail configured as a C-shaped irregular cross-section rail, in which the sliding part 1
