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

TECHNICAL AREA

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

STATE OF THE ART

For many purposes, such as the seating of large rooms, such as Conference and ballrooms, it is necessary that the chairs in a simple manner can be tidied up to save space and then set up again. To chairs are stackable vertically or horizontally.

A vertically stackable chair is e.g. known from DE 197 45 072 A1. This known chair has a leg frame, the laterally V-shaped tubes as legs, and a cross tube that the two side parts in their apices connects with each other. There are nubs on the underside of the cross tube provided, and on the leg ends sliding shoes. When stacking is the top one Chair with the nubs and the slide shoes on the lower chair.

The well-known chair is a less robust construction. Moreover, they tend Chairs when stacking to clamp, and therefore have to be very careful be placed on top of each other. The stacks tend to be unstable. Particularities, such as armrests or elements for chaining with other chairs to prevent panic, are not possible.

PRESENTATION OF THE INVENTION

It is therefore the object of the invention to provide a stackable chair design that on the one hand simple, robust and safe stacking possible but also special features such as armrests and panic protection can be provided, but nevertheless the chair is inexpensive to manufacture and is easy to assemble.

This object is achieved by a component with the features of claims 1 and of the subclaims solved.

The essence of the invention is the idea of a stackable chair with two over Truss-connected components in the form of "multifunctional nodes" equip, each comprising a cuboid base body, the Ends are chamfered, and the nose on its underside, and on its Has top grooves. This component holds the chair legs and the pins Traverses. When stacking, the oblique, centering ends of the Base the chair in the correct position so that the nose of the top Step into the grooves in the lower chair. This creates a stable fit one chair is reached on the other, even if the chairs are careless be placed on top of each other. The components of the invention, that is "multifunctional knots" can also armrests, possibly with Writing tablets, carry, or links for chaining with other chairs Panic protection.

WAYS OF CARRYING OUT THE INVENTION

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

With the component on the left side of the chair, the base body 1 can be seen, as well the front and rear leg pins 2 and 3. 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 into leg pins 2 and 3. The armrest 23 is in the front, not designated pocket of the component on the inserted the right side of the chair, the pocket 12 on the component on the left Corresponds to chair side. The other three pockets are unused. You can e.g. be closed with blind plugs.

2 shows the details of the component according to the invention. 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 Truss pins 4 and 5 are in the tubular shown in Figure 3 Trusses 19 and 20 inserted.

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

In Fig. 4 the chair already shown in Fig.1 is shown again, wherein - from Seen from the chair - the link 22 is shown at the left rear. This consists of a tab 24 with two pins 25, one of which is in the pocket 13 is inserted. The other pin 25 can then in the corresponding pocket of the neighboring chair.

The component according to the invention can e.g. are made of cast aluminum. It but can also be made of 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 by centering acting chamfered ends 6,7 of the base body 1 comes the upper chair always in the correct position so that the lugs 8, 9 of the upper chair into the engage corresponding grooves 10, 11 of the lower chair. This creates a very stable stack of chairs that is also very easy to take apart can be taken. The components are identical for both sides of the chair, and it A separate manufacturing, storage and assembly for left and right. This makes the chairs inexpensive to manufacture and easy to use can be installed quickly and easily with extras such as Armrests and interlinking elements can be equipped. In the pockets can e.g. seat numbers can also be used.
