NL7811186A - Chair for coupling into row - has coupling pieces inside legs on one side and outside on other - Google Patents

Abstract

The chair can be coupled to others to form a row, its two legs at each side being joined to each other by a curved middle portion. Both the front and the rear legs are coupled to those of adjacent chairs. At one side the coupling pieces are fixed to the inside of the legs (3, 5), and at the other to the outside of them. The two ends of a coupling piece can be flattened and bent sideways in opposite directions.

Applicant: Hermanus Marinus Plechelmus Engelbertink, Peterskamplaan 2, Oldenzaal.

Short designation: Linkable seat *

The invention relates to a folding chair, of which the two legs arranged on the same side merge into one another by means of a curved middle part and wherein both the front legs 5 and both the rear legs are coupled by means of a connecting piece.

Such a connectable chair is widely known in an embodiment in which the legs arranged on one side each comprise a vertically oriented hook-shaped element and wherein the legs arranged on the other side each comprise a vertically oriented bend-shaped element, which both elements are arranged on the relevant legs such that when two chairs thus constructed are placed next to each other, the two hook-shaped elements of one chair fit into the can-shaped elements of the other chair. By placing several chairs of this type next to each other and coupling them together, a row of seats is created which meet safety requirements imposed by local fire regulations.

Such a chair has the drawback that the four hook-shaped or bus-shaped elements must be secured to the legs 25 in the correct place and in the correct position, since otherwise the chairs cannot be coupled. Such a careful installation of said elements requires a lot of manufacturing time and therefore results in a substantial Q price increase of such a chair.

The present invention contemplates said drawback to this% 2.

liftable seat.

According to the invention, in the connectable chair of the type described in the preamble, the two connecting pieces are fastened on one side on the inside and near the other side on the outside of the legs concerned.

The invention will now be explained in more detail with reference to two figures, of which Pig. 1. shows an exploded perspective view of a first embodiment of a connectable chair according to the invention)

Pig. 2. shows a detailed representation of elements involved in the coupling 13 of a pair according to the invention manufacturing the seats) and

Pig. 3. shows a top view of a second embodiment of a connectable chair according to the invention.

20 in fig. 1 shows a connectable chair, which is composed of a metal frame 1 with four legs 2-5 and a seat 6 to be fixed on this frame 1.

The seat can be made of various materials, such as wood and plastic. The legs 2 and 4 and 3 and 5 attached to the same side of the chair are connected to each other via a curved metal center part 7 and 8, respectively. It is advantageous to manufacture such an assembly of legs 2 and 4, respectively 3 and 5 with curved central part 7 and 8 as a whole from a tube.

The frame 1 further comprises two connecting pieces 9 and 10, one of which (9) couples the two front legs 2 and 3 together, and the other connecting piece 10 connects the two rear legs 4 and 5 together. In this case, it holds that one of the front connecting piece 9 is 78 1 118 0

end 11 is attached to the outside of one leg 3 and the other end 12 to the inside of the other leg 2. For the other connecting piece 10, they are fastened in the same way, so that the ends of the two connecting pieces 9 and 10 located on one side of the chair are fastened to the inside of the two legs 2 and 4, while both are attached to the other the ends of the connecting pieces 9 and 10 located on the side of the chair are attached to the outside of the legs 3 and 5, respectively. Such a construction can be advantageously obtained by using a hollow pipe piece as connecting piece 9 and 10, the two ends being flattened over a certain length and in the opposite direction.

J are staggered laterally so that one end can be attached to the inside of a chair leg and the other end to the outside of a chair leg #.

When two identically manufactured chairs are now placed next to each other, the assembly of legs 3 and 5, wherein the connecting pieces 9 and 10 are attached on the outside, can be placed over the adjacent (and belonging to the other chair) assembly of legs 13 and 14 (with the connection pieces; J pieces 15 and 16 attached on the inside), and then lowered again. This creates a coupling between two juxtaposed chairs, which complies with local fire brigade regulations for holding meetings and the like.

In order to make the chair thus obtained also stackable, it is desirable to make each assembly of legs 2 and 4 and 3 and 5 slightly bent apart, so that when the chairs are placed on top of each other, the legs come together. \ \ \ \ 4.

Their particular embodiment of elements, which are involved in a pairing of two chairs manufactured according to the invention, is shown in Pig, 2.5. Instead of flat ends, the connecting pieces (such as 9 and 10) are provided with double-bent ends with which these ends are profiled in accordance with the round shape of the legs 13 and 14 involved in the coupling. The profile-ring of the end should preferably be adapted to the applied shape (round, square, etc.) of the legs. .

In order to obtain an amphitheater-wise arrangement of a row of chairs, it is possible to make the bend part co-acting with the next chair somewhat larger in one end.

their second embodiment of a connectable chair according to the invention is in section in Pig. 3, wherein the connecting pieces 20 between the relevant legs are directed slightly from each other, such that of one such connecting piece 9 and 10, one end is fastened on the inside to a leg 3 and 5 and the other end is attached to the outside. the other leg 2 and 4 is attached.

Here, too, the stackability of such chairs can be obtained by making each assembly of legs 2 and 4 and 3 and 5 slightly bent apart.

The parts belonging to the frame 1 can be of any desired material and profile, and can be hollow or solid.
