Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to one seat surface, two front legs provided on the side surfaces of the seat surface, and two seat legs similarly provided on the side surfaces of the seat surface and extending above the seat surface. A chair with two back legs and an arm and backrest.

[0002]

BACKGROUND OF THE INVENTION The subject of the present invention is particularly chairs (furniture) used in restaurants, offices, conference rooms and leisure facilities. In this application, when cleaning the floor, the chair should be removed from the place of use as easily, quickly and as possible to save space.

There are many known chairs of this type. For example, DE-G8322356.8 (German utility model application No. 83 22 356.8) describes a garden sofa, but this chair, like many other known types, is basically made of steel pipe. Yes, and has a stackable structure.

A stackable series of chairs is described in DE-PS3.805.206 (German Patent No. 3.805.206) as another prior art, but this chair has a mechanical mechanism. The manufacturing cost is high due to this. That is true of many so-called camping chairs.

Further, since all the stackable chairs have to be mechanically deformed, it takes time and requires manpower when they are taken out of the place of use, especially when many chairs have to be removed. Therefore, there is a drawback in that the cost of the arrangement of chairs cannot be paid when only cleaning is required.

[0006] Other simple stacking chairs require rational fabrication and are constrained in shape to obtain the stacking function, and usually the armrest is omitted. It is usually uncomfortable to sit in, as it will end up. Also, the appearance is not very good.

An object of the present invention is to provide a chair which has been made under the above circumstances and which does not have the above problems.

[0008]

The arm and chair with a backrest according to the present invention has features as described in claims 1 to 11 of the "claims". The basic features of the chair making up this invention are, as described in the main claim ("Claim 1"), for example, the end of the bend forming the armrest can be quickly attached to a table board or other tableware. It should be possible to hang it, and thus to ensure that the necessary floor clearance is achieved, such as when cleaning the floor. The arms and the backrest are integrally formed and assembled, and this form provides a chair which is not only comfortable to sit on but also maintains the above-mentioned function and is aesthetically configured. For example, it is suitable for beer holes.

The basic feature of the present invention is that the protrusions on the inner edges of the arms and the backrest allow the chairs to be hung on a table board and also stacked, so that they are located outside the outer edge of the seat surface. In addition, it is arranged with an interval corresponding to the thickness of the chair legs. In the chair thus formed, the features described in claims 2 and below are the more specific configurations of the present invention.

The most comfortable structure for the user of the chair of the present invention is the wooden chair described in claims 2 and 3. However, the present invention is not limited to configurations made of this material. The trapezoidal joining piece may be made of plastic or metal, in which case the entire chair can be made of the same material.

In order to ensure a stackable form, the chair leg is separated from the seat edge, so that it is also possible to manufacture the above-mentioned connecting piece completely with the chair leg or the seat edge. Enter the range.

[0012]

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings (FIG. 1).

The drawing shows a chair with the basic features of the invention. The circular seating surface 5 shown here is constructed by fitting a plate into the ring,
The present invention is not limited to this aspect. Other bearing surfaces can be used as well, as long as they are dimensioned to achieve the features of the present invention. The rear leg 3 of the chair extends upward and has a slit in the upper part thereof, and the narrow side of the trapezoidal joining piece 2 is fitted into this slit. The wide side of the joining piece 2 is fitted into a slit (not shown in the drawing) on the side of the circular curved portion 1 forming the arm / back, and this portion is joined by "glue". It The curved portion 1 has a slope of at least 5 ° with respect to the seat surface 5 as shown in FIG. In that case, the end 4 of the curved portion 1 is determined to be positioned above the center of gravity of the chair so that the chair can be stably hung in the vertical direction when hooked on the table plate and hung.

In this state, for example, a plastic contact surface 7 is attached to the end 4 in order to prevent the table plate from being scratched.

In order to ensure the optimum stacking state of the chair of the present invention, the distance between the highest point of the backrest and the upper edge of the seat surface 5 is the distance between the lower edge of the seat surface 5 and the chair rising surface (lower end surface of the chair). Must be less than the spacing. In addition, the part where the vertical thickness of the arm / backrest is increased (thickened part)
Must be less than or at most the same as the thickness of the inset plate including the vertical bearing surface 5 thickness, ie the bearing surface 5 edge thickness.

In order to protect the chairs in the stacked state, the seating surface 5 or the edge of the connecting piece 6 is fitted from below with a suitable cushion not explicitly shown in the drawing.

In the chair manufactured according to the present invention, it is more preferable that the arms, the backrest, and the legs have an elliptical cross section.

All the features shown in the above description, the above-mentioned claims and the drawings may exist individually or freely combined with each other, and the basic technical idea of the present invention. Belong to.

[0019]

According to the present invention, since the chair according to the present invention is constructed and operates as described above, it is comfortable for the user to sit and can be easily removed from the place of use when cleaning the floor or the like. In addition, the original state can be easily restored. In addition, it can be beautiful in terms of aesthetics.

Moreover, since no mechanical mechanism is structurally provided, it can be provided at low cost.
