Cord for innerspring

/ ~ \ The innovation relates to a cord for spring cores, the spiral springs of which are connected to a spring package secured in their position and on a furniture frame ο. Like. Carriers are attached. Cords for such innerspring have the task of deforming the innerspring itself by approximately parallel displacement of the upper turns of its spiral springs relative to the lower turns in such a way that outer regions of the turns of the spiral springs located along an edge contour are pulled forward to about the outer border of the furniture frame.

Previously known cords form a simple piece of thread that is attached to an upper turn of a displacement ( · Knotted towards the rear spiral spring, then over the

upper turn of the next front spiral spring away |: pulled and also · is knotted with this, after which the | Lacing thread pulled through to the front edge of the furniture frame in the displacement direction and after exercising the | storage-causing train on the furniture frame by staples o. The like. Is set.

. A. Lacing of innerspring with the help of such cords is extremely time-consuming and causes considerable costs.

by innovation the task is based on a string

to create that quickly and easily with a suitable Endwindurig a spiral spring of the spring core is connectable •.

To solve this problem, the cord is characterized by the features in the characterizing part of claim 1 specified features. With regard to further refinements, reference is made to claims 2 to 5.

to The cord for the innovation is extraordinary cheap to manufacture and by simply latching its hook on the desired turn of a spiral spring can be fixed, while at the same time ensuring that an unintentional detachment of the hook is excluded.

After the hook has latched in, the cord can be easily pulled through to the front edge of the furniture frame and be determined there in a known manner. The formation of the hook from plastic is not only here for reasons of low manufacturing costs, but also advantageous because with relative movements between the hook and the associated turn of the coil spring, as they are in use with such a spring core furniture are unavoidable, no noise is generated.

An embodiment of the subject of the innovation is illustrated in more detail in the drawing. In the drawing demonstrate:

Fig. 1 is a schematic side view of a

a furniture frame with attached spring core a lacing by means of a cord according to the innovation, and FIG. 2 shows a broken side view of the cord with his hook.

The cord 1 consists of a separating melt

~

divided section of an endless, cut length one behind the other with molded hook 2 provided plastic cord and accordingly has at its end shown in Fig. 2 a single hook 2, which in turn consists of plastic and is preferably directly molded or cast on. The thereby on

'' Hook 2 attached to the cord 1 has a pick-up

seat 3 for a turn 4 of a coil spring 5, the Forms part of a spring assembly 6. This receiving slot is provided at its entry end with a beveled intake surface 7 and also with a locking shoulder 8, of which the former facilitates the latching of the hook and the latter a releasing of the hook2 of one Prevented spiral spring winding.

1.5

The cord 1 is passed through the shaft part 9 of the hook 2 and ends immediately behind the head 10 of the hook 2, at this (as well as at its other) end it has a bead-shaped thickening 11, which is formed by the separating melting process, e.g. by means of a hot or glow wire.

Fig. 1 illustrates the spring assembly 6 in its deformed position by - lacing and leaves the course of the lacing thread 1 can be seen at its right-hand end 12 in FIG. 1 by fastening means (not shown) Is set on the frame 13 of a piece of furniture or the like.
