The special couch frame according to the invention consists of a plurality of metal frame members, consisting of round, rear and intermediate lateral connecting parts. These metal links are flanged and the frame parts are designed so that cushioning material can be attached to them. The flanges are arranged so that the cushioning material can be applied in the plane of the flanges and clamping devices are used to attach the material to the flanges.

The stapling device used in the practice of the invention consists of U-shaped members that have the shape of channel sections. These links consist of one Base and side surfaces which are formed in one piece with the base. The side walls extend at an angle inwards relative to each other, creating a small opening is formed between the outer edges of the side walls. The size of this opening is less than the associated thickness of the Flange and the padding material associated with it. The opening formed between the side walls in the Plane of the base, but is approximately equal to or greater than the associated thickness of the flange and the associated one Upholstery material.

The brackets are made of plastic or other resilient material trained and suitable to be brought into a position to hold the padding material relative to the flanges. This will move the side walls out of their normal position

pressed to engage the cushioning material and d.en. in order to connected flanges to come.

The couch frame 10 shown in Figure 1 is suitable to accommodate a collapsible bed frame. The bed frame is shown in dashed lines at 12 and it is indicated that any suitable bed frame can be used »- ·

The couch frame consists of a front frame part 14, which extends transversely between the side frame parts 16. The rear Frame part 18 also extends transversely between the side frame parts.

As best seen in Figure 4, ₉ the front frame defines upper and lower flanges 20 and 22. This frame can be formed in one piece with a rib 24 for reinforcement _{or the like}

Side frames 16 each consist of an upper rail 26 _{g of} a middle rail 28 and a ground rail 30. The rear frame forms a top rail 32 and a transversely © rstreckende rail 34. An additional transversely extending bar 36 extends between the side frame members 16 "

As best seen in Figure 3, the headrail 26 defines downwardly extending flanges for each side frame member 38 and 40. The intermediate rail 28 forms downwardly extending Flanges 42, while the bottom rail 30 forms an inwardly extending flange 44.

Figure 5 shows the lower end of the rear frame rail. This rear frame rail forms an upward direction extending flange 46. The additional frame schsie forms an upwardly extending flange 48 as seen in FIG.

The frame members described are particularly suitable for attaching cushioning material. Looking at the front frame member 14, cushioning material 50 is provided therewith to extend from the top flange 20 entirely across the front of the surface of the frame member and then to lie in a position around the base flange 22. The material is suitably held in place on this frame member by clamping devices 52. As best seen in Figure 2, each bracket 52 defines a base 54 with opposing side walls 56 connected thereto. The clips are molded from a resilient material such as polyethylene, polypropylene or similar plastic material. The channel-like cross-section appears in its normal condition in FIGS. 2 and 4, the entry part 58 having a relatively narrow opening due to the angled arrangement of the side walls 50 =, the size of the opening 58 is smaller than that of the thickness of the connected cushioning material 50 that surrounds the associated flange is mounted, and to ensure a good fit zn _8, the size of the aperture may be equal to or less than the flange thickness to be alone.
