Detachable garden and terrace chair

The present invention relates to a demountable garden and terrace chair made of metal tube and tubular frame part with seat and back made of elastic material, with two fixed side frames and a front one Bridge with a firmly connected tubular frame seat part as well as a rear bridge with a firmly connected tubular frame back part are releasably connected to one another, the open ends of the tubular frame seat part with those of the tubular frame back parts are releasably connected.

Garden and patio chairs of the aforementioned type are on known. The dismantling of such garden and terrace chairs is used in particular that such a Chair packed in a special box in a very small space can be. A chair packed in such a small space can be conveniently transported by an end user, for example in a passenger car, and at the installation site can be easily assembled without a great deal of technical knowledge.

In the known garden and patio chairs of the aforementioned type, there are bridges over which the side frames can be detachably connected to each other, made of tubular profiles, whereby the required stability of the composite Chair is guaranteed, but this leads to still relatively high manufacturing costs, on the one hand due to the required material ineatz and on the other hand due to the fact that in the connection area between the bridges made of pipes and the side frames, special precautions must be taken to ensure that they are flawless To effect connection of the pipes to the side frames. Besides, it is, albeit primarily For optical reasons, it is necessary to equip the open head ends of the tubes with sealing caps.

The present invention is based on the object of providing a removable garden and patio chair of the generic type Kind to design so that both the required material input is reduced and the assembly work is simplified can without compromising the stability and stability of the chair.

The solution to this problem is, according to the invention, that the front and rear bridges are made of shaped sheet metal parts

130040/0379

exist, which are each deformed in the area of their head ends according to the cross-section of the side frame profiles and the side frame profiles in the connection area partially grip around and in its central area with an approximately right-angled support tab on which the pipes are attached by tubular frame seat part or tubular frame back part, are provided.

The use of shaped sheet metal parts for the detachable connection of the side frames with one another is compared to the previously known construction achieved a considerable saving in material without compromising the stability and stability of the assembled chair suffers, as each bridge is absolutely stable due to the bevelled support bracket and stable connecting part is created.

Since the bridges are deformed in their head end area in such a way that they partially encompass the side frame profiles, an absolutely secure and problem-free connection is also possible here.

In the further embodiment of the invention it is provided that each sheet metal part on the head side by means of a screw, which is screwed into a captive nut in the side frame is attached.

This means that only four screws are required to attach the two bridges.

Another idea of the invention is that on each sheet metal part above and below the screw connection Expressions are attached, which in corresponding recesses or holes in the side frame profiles intervention.

130040/0379

This simple manufacturing measure ensures that despite the use of only one screw for connecting a sheet metal part to a side frame profile, a high degree of lateral stability of the entire chair is guaranteed even under high loads.

Further features of the invention are the subject matter of further subclaims and emerge from the following description of the embodiment shown in the drawings. Show it:

The garden and terrace chair shown in Figi 1 consists essentially from the two side frames 1 and one

130040/0379

Tubular frame part 3, which, as particularly shown in FIG. 2 very clearly, consists of a tubular frame seat part 4 and a Tube frame back part 5 is formed.

The tubular frame seat part 4 is just like the tubular frame back part 5 with a transverse to the seat surface or to the backrest surface extending bridge 6 is provided, which is firmly connected to the tubular frame seat part 4 or tubular frame back part 5.

In FIGS. 1 and 2, for the sake of clarity, the representation of a seat and back part made of elastic Material that is attached to the tubular frame part 3 in the fully assembled garden and terrace chair has been omitted.

Each bridge 6 is designed as a sheet metal part and each deformed in the area of their head ends 7 according to the cross section of the side frame profiles 8, so that each one head end 7 of a bridge 6 partially engages around the side frame 1. This can be seen in particular from FIG. 7.

The bridges 6 are provided between their two head ends 7 with an approximately right-angled support tab 9, which on the one hand contributes to the stiffening of the bridges 6 and on the other hand a relatively large support and Mounting surface for the tubular frame seat part 4 or the Provide tubular frame back part 5.

In the area in which the tubular frame seat part 4 or the Tube frame back part 5 is attached to the bridges 6, the same are provided with bulges 10, the radius of which is the Corresponds to the radius of the pipe used for the aforementioned parts.

130040/0379

The bridges 6 are preferably connected to the tubular frame seat part 4 or the tubular frame back part 5 by welding.

The bridges 6 are connected to the side frames 1 by means of one provided in each head end area Screw 11 which are screwed into a nut 12 which is captively fixed in the side frame profiles 8.

The nuts 12 can be so-called press-fit nuts, but there is also the possibility of any To fix the nuts within the side frame profiles 8 so that they cannot be lost.

In the area where the nuts 12 in the side frame profiles 8 are arranged, the profiles are provided with an outwardly directed bulge 13 which is in an im Corresponding indentations 14 provided in the area of the head ends 7 of the bridges 6 engage,

To increase the lateral stability of the entire garden and terrace chair is provided above and below the screw connection at the head ends 7 of the bridges 6 the side frame profiles 8 to attach directional expressions 15, which in corresponding depressions or holes the side frame profiles 8 engage.

To increase the Eigensteifigke.it and strength are the Bridges 6 are provided with at least one bead 16 running in the longitudinal direction.

8 and 9 show that in the connecting area of the tubular frame seat part 4 and tubular frame back part 5, the respective tube ends are pushed into one another.

. 3011H2

In the illustrated embodiment, the ends of the tubular frame back part 5 are tapered so far that the same in the open ends of the tubular frame seat part 4 can be inserted. In each end of the tubular frame back part 5 a shaped spring 17 is arranged with an angled nose 18, the nose 18 through an opening 19 of the tubular frame back part 5 passes through. The nose 18 projects beyond the outer diameter of the tubular frame back part 5 and when the tubular frame seat part 4 and tubular frame back part 5 are pushed together, the aforementioned nose snaps into an on Tubular frame seat part 4 attached recess 20 a. This results in a further axial displacement of the tubular frame seat part 4 and the tubular frame back part 5 prevented relative to one another.
