Stackable chair unit

The invention relates to a stackable, composed of at least one seat and of at least two leg side parts connected by a cross bar existing chair unit that can be connected to adjacent chair units.

In the case of chair units of the aforementioned known type, there is the Disadvantage that if these are connected to one another in a row if additional devices are required, which establish the connection from chair unit to chair unit.

The object of the invention is to create a chair unit that both stackable and can be connected to other chair units in a row without the need for additional devices.

The invention solves this problem in that the neighboring leg » Side parts of two chair units standing next to each other form-fit can be coupled to each other ·. '

A preferred embodiment of the invention is that on the one outside the first leg side part a downwardly open, in cross-section hood-like profile and on the other outside the second leg saddle part has a cross section which is slightly smaller than the free cross section of the hood-like profile of the first leg side part

dimensioned is »This makes it possible to use the side part of the leg with a larger Cross-section of one chair unit onto the "adjacent leg side part Smaller profile cross-section of a chair unit arranged next to it to be attached and in this way the form-fitting row connection to manufacture the chair units *

The cross section of the leg side parts can be U-shaped. Here you can the legs of the U-profile have a point that opens downwards Make angles.

According to a further embodiment, the cross-sectional profile can Leg side parts can also be designed arched.

Yet another embodiment provides an angled cross-section profile of the leg side panels.

The side parts of the legs expediently form an inverted " The chair units are stacked, especially when it comes to the shape of the body adapted backrest, made easier by the fact that the front chair leg the side of the legs is steeper than the back leg of the chair.

The stacking and convenience of the user are also provided by the Measure that the apex of the leg side parts are flattened on the top are.

The necessary stability of the chair unit is next to the leg parts produced by an angle profile that is open at the bottom, the di © leg » • connects side parts in the area of their crown; where in the stacked » State the lowest of the angle profile on the sit of the one below Chair unit rests »

The feet of the. Leg side part »are expediently made as pre-sucked tabs formed the profile.

The invention is illustrated, for example, in the drawing. "

Show it.

In Fig. 1 two chair units 1 a, 1 b are shown, each of which consists of one

pressed seat shell 2, which are fastened on a transverse web 3 · g

The crosspiece 3 consists of a downwardly open angle profile

the ends of which leg side parts 4a, 4b are attached. The leg side part form an inverted T in side view and are in the area of

The apex connected to the crosspiece.

The leg side part 4a consists of a profile that is open near the bottom like a hood and has feet 4c at the lower ends, which from are formed from the profile protruding tabs.

The leg side part 4a has a free cross section that is somewhat larger dimensioned as the cross section of the leg side part 4b on the other Outside of the chair unit, so that the leg side part 4a of the one Chair unit Ib on the leg side part 4b of the other chair unit la

attached and in this way positively connected to this can be. This positive connection is illustrated in FIG. 2, which shows that in a front view the leg side part 4b is completely covered over by the leg side part 4 *. In this way you can arbitrarily long rows of chair units are made.

In detail, Figures 3 and 4 clearly illustrate the type of formechlüeaigen coupling of the leg side parts 4a and 4b of adjacent ones Chair units.

It can be seen that the end faces of the crossbars 3 are attached to the outside of the leg of the U-shaped cross-section of the leg side parts 4a and 4b, for example by welding, in such a way that the inner surfaces of the crossbars with the sub-accounts of the angled legs The side parts of the legs are aligned · In this catfish, enough space is created upwards so that the side part 4b can reach into the apex area of the side part 4 & ^from below. In order to ensure sufficient play and greater comfort for the user, the leg side parts are flattened at 4d on the upper side of their vertex. The coupled position of the two leg side parts is shown in Flg. clearly recognizable, the non-visible edges of the covered leg side parts 4b being indicated by dashed lines

According to FIg * 5a let the. Cross-section of the side parts 4a and 4b formed from a right-angled ü. The interlocking interlocking of the two profiles and the inverted V-shape of the side parts make it possible to move or move several chair units »6a« connected to one another in a row _? without the chair units separating from each other

As a deviation from the cross-sectional shape according to FIG. 5a, the profile handles 5 "and 5b according to FIG. 5b are spread apart so that they follow one another Form an acute angle that opens on the outside

According to Fig. 5c, arcuate leg side parts 6a, 6b are provided.

5d shows, as the side parts, angle profiles 7a, 7b, which are in a positive lag · are arranged.

Finally, Pig illustrates. 6 stacked on top of each other · chair units

according to the invention, whereby it can be seen that the front chair legs 6a are steeper than the assigned rear chair legs 8b.

This configuration facilitates stacking, taking into account the Seat-back unit that is largely adapted to the shape of the body This includes what is not shown in the drawing for the sake of clarity.

is placed, the lower edges of the transverse webs 3 each on the top ^ of the seat of the chair unit below.

In a departure from the exemplary embodiment described, chair units are also conceivable in which several seats are supported by corresponding frames are connected with each other, but again with the stipulation that there Profile of the side leg part on one outside of such a chair unit is greater than the profile of the side leg part on the other Outside of such a chair unit so that it is possible to adapt to different · parts of halls with rows of chairs of different lengths from chair units with a different number of seats. It is also self-evident that in the same way "also Bench · can be designed.
