EP1393656B1 - Connecting member for a stackable chair - Google Patents

Abstract

The part (1) of a stackable chair comprises a block-like central section with wedge-like end elements (6, 7), leg and transverse pins (2, 3; 4, 5), pockets (12, 13) and corresponding vertical protrusions (8, 9).

Description

The invention relates to the field of seating, in particular a component for a stackable chair for the multipurpose area.

STATE OF THE ART

For many purposes, such as the seating of large spaces, such as Conference and party halls, it is necessary that the chairs in a simple manner to save space and then be put up again. To Vertical or horizontal stackable chairs are common.

A vertically stackable chair is e.g. known from DE 197 45 072 A1. This Known chair has a leg frame, the side bent V-shaped tubes includes as legs, and a cross tube, the two side panels in their vertices connects with each other. At the bottom of the cross tube are support pads provided, and on the leg ends sliding shoes. When stacking is the upper Chair with cushions and sliding shoes on the lower chair.

The well-known chair is a little robust construction. Moreover, the tend Chairs when stacking for clamping, and must therefore very carefully be juxtaposed. The stacks tend to be unstable. Particularities, such as armrests or elements for concatenating with other chairs for panic protection, are not possible.

PRESENTATION OF THE INVENTION

It is therefore the object of the invention to provide a stackable chair so design that on the one hand a simple, robust and secure stacking possible On the other hand, there are also special features such as armrests and panic protection can be provided, but still the chair inexpensive to produce and easy to install.

This object is achieved by a component having the features of claim 1 and the dependent claims.

The core of the invention is the idea of having a stackable chair with two over Truss-connected components in the form of "multifunctional nodes" equip, each comprising a cuboid base body whose Ends are bevelled, and the nose at his bottom, and at his Has top grooves. This component holds over pin the chair legs and the Traverses. When stacking bring the oblique, centering acting ends of Base body the chair in the correct position, so that the noses of the upper Chair into the grooves of the lower chair. This will be a stable seat one chair on the other, even if the chairs are unsafe be put on top of each other. The components of the invention, ie the "multifunctional knot", can also armrests, possibly with Writing trays, carry, or links for linking with other chairs Panic protection.

WAYS FOR CARRYING OUT THE INVENTION

In Fig. 1 is a chair with a seat plate 16, a backrest support 17 and a Backrest 18 shown. The chair points on its two sides below the seat plate 16 each an inventive component, a "multifunctional Knot ", of the component on the right side of the chair only the rear, empty pocket 13, and the front pocket with the armrest 23 can be seen.

In the component on the left side of the chair, the base body 1 can be seen, as well the front and the rear leg journals 2 and 3, respectively. The base body 1 has the Ends 6 and 7, which are beveled sideways. There are also the noses 8 and 9, as well as the grooves 10 and 11. Furthermore, the pockets 12 and 13 shown.

As can be seen, the four chair legs are inserted in the leg pins 2 and 3. The armrest 23 is in the front, not designated pocket of the component on the the right side of the chair is inserted, that of the bag 12 in the component on the left Chair side corresponds. The other three bags are unused. You can e.g. closed with blind plugs.

In Figure 2, the component according to the invention is shown in its details. In addition to the details already described in Fig.1 here are also the Pads 14 and 15 shown, as well as the truss pins 4 and 5. Die Traverse pins 4 and 5 are in the illustrated in Figure 3, tubular Traverses 19 and 20 inserted.

In the assembled state, the seat plate 16 on the support lugs 14, 15, the e.g. made of rubber, screwed on.

In Fig. 4, the chair already shown in Figure 1 is shown again, wherein - from Chair ago seen - left behind the link 22 is shown. This consists of a tab 24 with two pins 25, one of which is in the bag 13 is inserted. The other pin 25 can then in the entspechende bag the neighboring chair are plugged.

The component according to the invention may e.g. Made of cast aluminum. It but also from a suitable plastic, for example glass fiber reinforced polyamide, with metallic inserts.

As can be seen, the chairs can be stacked without special care, they can be thrown into each other, so to speak, but through the centering acting bevelled ends 6,7 of the base body 1 comes the upper chair always in the right position, so that the noses 8, 9 of the upper chair in the corresponding grooves 10, 11 of the lower chair intervene. This creates a very sturdy stack of chairs, but also very easily apart again can be taken. The components are identical for both sides of the chair, and it therefore eliminates a separate manufacturing, storage and installation for left and right. Thus, the chairs are inexpensive to manufacture and easy to but you can still quickly and easily with extras such as Armrests and interlinking elements are equipped. In the pockets can z. B. seat numbers are used.
