Spring core for upholstery and the like

The innovation relates to a rat-spring for upholstery and the like. DE-PS 1 155 218 i shows a spring core of this type, consisting of several, each | Rows of springs formed from a spring wire with alternately j right and left coiled coil springs, each of which consists of i head and foot coils and an intermediate coil body with two coils.

running spiral ά, .egen in the upper and lower boundary level of the spring core, in the amount of the two adjacent and interlocked legs of the to form the Head and foot coils specific parts of the springs and around! loop these interlocked legs. Through this arrangement the transverse helix is an inherently stiff, i.e. inflexible, spring core. In practice, however, there is a need after flexible innerspring as part of upholstery and the like, since beds are increasingly made up of two parts Base springs are used, the two parts of which are hinged together and for the purpose of adapting to the body shape of the user are infinitely pivotable against each other.

This is where the idea of innovation kicks in. The innovation is based on the task of making the spring cores flexible, so these can easily adapt to the shape of the two mutually pivotable parts of the spring base.

The innovation thus relates to a spring core for upholstery and the like, consisting of several rows of springs, each formed from a spring wire, with coiled springs alternately to the right and left, each of which consists of head and foot windings and an intermediate winding body with preferably two windings, whereby the parts of the coil springs intended to form the head and foot windings are U-shaped, the straight U-legs and the straight web are parallel to the longitudinal and transverse directions in the upper and lower boundary plane of the spring core, each opposite to the right and left-hand winding bodies are hooked into one another in the area of one of their two winding planes and the rows of springs are connected to one another via transverse and parallel coils. She ! is characterized in that the helix lie at the level of the hooking points and the hooking turns of the winding bodies wrap around in the hooking area. \

Due to the design according to the innovation, the spring core is extremely flexible in itself, so that it conforms to the shapes over a two-part spring base as a bed insert can easily follow.

An embodiment of the renewal proper spring \ core is still somewhat illustrated below based on the drawing j. In this show in a purely schematic way:!

Fig. 1 is an isometric partial representation of a spring row of the spring core according to the innovation,!

Fig. 2 is an isometric partial representation of two rows of springs in an exploded view of the Spring core according to the innovation,

Fig. 3 is a partial view of the spring core according to the innovation,

Fig. K shows a vertical section along the line

IV-IV and a top view of the arrangement! according to Fig. 3,

Fig. 5 is a partial representation of the spring core according to the innovation, the spring core on a multi-part bed frame is arranged, which consists of three hingedly connected Parts consists of which the two end parts are pivotable,

Fig. 1 of the drawing shows an isometric view of a row of springs from which the spring core is constructed is. Each row of springs consists of a single spring wire. Each row of feathers consists of alternating left and right coiled springs 1,2.

Each spring 1, 2 consists of head windings 1a and foot windings 1b or 2a, 2b and an intermediate winding body 3, 4. In the embodiment shown, has the winding body 3 or 4 has two turns 3a, 3b and 4a, 4b. However, the innovation is by no means restricted to this; much more more or less than two turns are also possible and conceivable.

As FIGS. 1 and 2 show, those for forming the head and foot windings 1a and 1b or 2a, 2b are the jump;

! springs 1, 2 certain parts are U-shaped, the straight U-legs 1c, 2c or 1d, 2d as well as the straight web 1e ^! and 2e lie parallel to the longitudinal and transverse directions in the upper and lower delimitation plane of the spring core.

i As can be seen from FIGS. 1 and 2, each

Opposite, right and left wound winding bodies 3, 4 hooked into one another in the area of one of their two winding planes. In FIGS. 1 and 2, the hooking points are denoted by 5 j and 6. By hooking, which in its effect ! is tantamount to a tangle, but is much easier to manufacture, the result is an interlocked row of springs, which : curl up and save without using a drum j lets. This means that the row of springs can be removed by machine and saves labor.

j The individual rows of springs are now

! spiral 7, S assembled and connected to one another. As in-! For example, FIG. 2 of the drawing clearly shows that the coils 7, which run transversely and are spaced apart from one another, are located or 8 at the level of the hooking points 5 and 6 and loop around the hooking turns 3b and 4b or 3a and 4a.

The transverse Wenael 7, 8 lying between the upper and lower delimitation plane of the spring core form hinge joints through which flexibility of the spring core is ensured to a certain extent, as shown in FIG. 6 , for example.

This flexibility allows the spring core to adapt to a spring base 9, which consists of the three parts 9a to 9c, wherein the head part 9a and the foot part 9c of this spring base 9 are articulated to the middle part 9b. Will the head part 9a and the foot part 9c brought into the position shown in Fig. 5 of the drawing, then the innerspring can Due to its flexibility, it can be easily adapted to the shape of the bed base. During the transfer of the The spring core from the position shown in Fig. 3 to the position shown in Fig. 5 is removed at the kink in the the upper boundary plane of the spring core lying two adjacent, straight U-legs 1c and 2c from each other, whereby a constraint-free kink is only possible.
