The invention "relates to a frame for folding furniture and more particularly relates to a decorative hanger for use as the back or seat of a folding chair or Deck chairs.

There are already various folding furniture structures known in which tubular material as a support for the User is provided. In many cases the hose has been chosen from different colors around the frame to give a decorative appearance. For example, tubing was sometimes placed around the tubular frame. of different colors alternately wrapped around a different

to create a colored pattern.

In order to produce frames of this type *, however, a number of process steps were previously necessary in order to create the hoses different colors to be attached to the frame. It also took a fair amount of time to put the tubes in hers to be applied correctly in each position in order to obtain the desired color sample.

As a result, the invention has for its object to provide a frame with a multicolored pattern on the is made in a simple manner. The object of the invention is also to provide a frame with an attractive appearance for a folding piece of furniture to create »Furthermore, it is an object of the invention to create a multi-colored frame for a folding chair, which can be easily produced within a short time.

In short, according to the invention, a frame for folding furniture, for example chairs or deck chairs, is used created outdoors, the appearance of which is multicolored · The frame is made of a rigid frame, for example constructed in a tubular, U-shaped construction, around which a hose is wrapped in a series of turns so that that a surface for supporting a user is formed. The hose is extruded as a unitary, integral Material and includes a tube portion and a strand portion which are integrally formed. In addition, the Hose part has a larger diameter than the strand part and also has a surface of a different color than the surface of the strand part.

To assemble the frame, the tube of the multicolored piece of tubing is attached to the rigid U-shaped one at one end Frame attached and then wrapped around the frame in a series of turns. This will do the rest of the end of the hose is also attached to the frame.

The invention and advantageous details of the invention

Application are described below with reference to drawings of an exemplary embodiment explained in more detail.

Figure 7 is a section taken along line 7-7 of Figure 6 showing the extruded profile in cross section.

As FIGS. 1 and 2 show, the chair 10 is better known with " Leg construction 11 and also known armrest construction 12 executed. In addition, the Chair 10 has a seat 13 and a backrest 14, each on the leg structure 11 and on the armrest structure

12 are attached so that they can be folded together into a collapsed and an expanded position. The seat

13 and the backrest 14 are made in an identical manner, so that in the following, only the backrest is explained in more detail.

It can be seen from FIGS. 1, 3 and 4 that the backrest I4 consists of a frame which is U-shaped Frame 15t, for example, made of tubular aluminum construction and an extruded profile 16 which is shaped around the TJ Frame 15 wrapped around in a number of turns 17 is. The extruded profile 16 consists of a hose part 18 and a strand part 19 «These two parts 18 and 19 are integral along their length

009839/1276

to each other. In addition, the strand part 19 has smaller cross-sectional dimensions than the hose part 18, i.e. for example that the strand part has a smaller diameter than the hose part 18.

The extruded profile 16 is U-shaped, tubular Frame 15 by means of appropriate fasteners 20, for example a number of threaded screws attached. These threaded screws 20 extend through the ends of the extruded profile and also through intermediate sections of the profile 16 in Sohraub thread engagement with the U-shaped frame 15 · These threaded screws 20 can also be used with appropriate Washers or heads 21 - be provided so that a larger contact area with the material of the extruded profile 16 is created to tear off the extruded profile from the threaded screws 20 to prevent. The drawing shows that the ends of the extruded profile 16 at the inside of the U-shaped frame 15 are attached, while, the intermediate sections of the hose to the rear of the U-shaped Frame 15 attached to slfed.

With reference to Figures 1 and 1, it should be noted that the extruded profile 16 is made of a plastic, for example vinyl plastic, of a uniform color. In addition, the strand part 19 is provided with a coating 22 in a second color, which differs from the color of the extruded profile 16. This coating 22 is applied to the entire exposed surface of the strand part 19, so that the extruded profile is given a color effect in two tones .

In order to provide the extruded profile 16 with the coating 22 on the strand part 19, as shown in FIGS. 6 and 7, a Plastic compound for the injected product through an appropriate one Hose injection mold 23 (Figure 6) passed, which brings the mass to be processed into the desired shape. For example the extruded profile 16 becomes a hose part 18 '

009839/1276

with a circular cross-section and a strand part 19 with also shaped circular cross-section, with both parts 18 and 19 along a longitudinally extended surface area are intimately connected «At this point in the manufacturing process, the extruded profile has a overall uniform color β. Then the extruded one runs Profile 16 by a coating-applying arrangement 24 of known type within it, not shown here of the extruder where the paint coat 22 is applied around the strand portion

As Figure 5 shows, for the manufacture of the backrest frame, the extruded profile 16 attached to a En & e by means of a threaded screw 20 just ara -UF örmigen frame 15 and then shaped U-around frame 15 is wound, is to its lower area reaches " The extruded profile 16 is then cut off and likewise fastened to the U-shaped frame 15 by means of a further screw, for example. There is also the possibility of dimensioning the extruded profile to the required length from the start before it is wound around the U-shaped frame 15. As a further alternative, the extruded profile 16 can be wrapped over only part of the length of the U-shaped frame, while a second piece of extruded profile 16 is wrapped around the remainder of the U-shaped frame a plurality of screw-threaded screws 20 may be attached to intermediate portions of the extruded profile to hold the turns of the extruded profile in place on the U-shaped frame 15.

According to the invention there is thus a frame for folding furniture with a supporting surface in a two-tone color scheme created, which is made in a relatively simple manner. The supporting surface of the frame is made from an extruded profile comprising several parts, one part of which is made in one color "

009839/1276

and a second part is covered with a second color. For example, the larger part can be provided in a turquoise color, while the smaller strand part is a dark blue Color coating is given »The individual. Parts of the extruded profile too be provided in different shades or tones of the same color, for example with a helloli / eri part and a dark olive part.

According to the invention, a frame is also provided, which is easily assembled in such a way that it has a two-tone appearance »Da the extruded profile with uniform hose part and strand part in different Farben, all you need is the extruded profile in a one-step process around the tube-like, IT ~ shaped frame to be wrapped. In addition, precisely because of this one-step process, the position of the hose part remains in relation to the strand part always the same, so that no separation between the two parts can occur would disturb the aesthetic appearance of the chair having such a frame. The execution of the extruded Profile in two parts with different cross-sectional dimensions gives the supporting frame of the chair an even more attractive one Appearance without reducing the strength of the supporting surface. In this regard it should be noted that any load on .one or more turns of the extruded Profile is applied, is transmitted through both parts of each turn. This makes it possible that the increased Strength of the common surface between both parts part of the impact and loading stresses of the supporting ones Absorbs area.
