Description

[0001] Suspending band for furniture [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resilient supporting band for furniture which is installed in a frame such as a bed, a sofa, a chair or the like to elastically support the upper mattress. More specifically, Since the first yarn and the second yarn are wound by being crossed in the X-shape to be caught by holding the yarn in the spiral direction twice instead of once, the length yarn does not lose the elasticity even after long use and the elastic restoring force and tensile strength are improved, And more particularly to a resilient supporting band for furniture having excellent supporting effect.

Generally, furniture such as a bed, a sofa, a chair, and the like has a structure in which a mattress is seated on an upper part of a frame formed of wood, steel, etc., and a supporting member is provided on the frame to support a lower part of the mattress.

The supporting member has a function of stably supporting the mattress and a function of dispersing a load acting on the mattress. The supporting member is made of a wood or metal plate which is supported with no elastic force against a load acting on the mattress, There is an elastic supporting band elastically supporting the load.

The support member formed of the wood or the metal plate absorbs the impact applied to the mattress only by the mattress itself because the support member is not provided with the shock absorbing function and the elastic support band absorbs the impact applied to the mattress first by the mattress, It is possible to provide a more comfortable feeling because it is absorbed secondarily by the support band.

The conventional elastic support band is manufactured by weaving a plurality of long-distance moving members located in parallel in the width direction by a connecting yarn and fixing both end portions on the frame top.

1, the yarn 5 'is spirally wound around the core 4' having elasticity as shown in FIG. 1 to support the core 4 '. Thus, when the core is stretched or returned, It is the role of the Lord.

However, since the conventional elastic supporting band is spirally wound with a single yarn 5 'on the outer side of the core 4', the force to catch it when the core is stretched or returned is weak. Therefore, The resilient force or the tensile strength gradually decreases and the impact applied to the mattress is not absorbed. In addition, the mattress can not be horizontally supported and sagging occurs, thereby deteriorating the quality and durability of the product.

Disclosure of Invention Technical Problem [8] The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide a yarn removing method for yarns, The first yarn and the second yarn are wound in an X-shaped crossing manner so that the elastic yarn does not lose elasticity even after long use, and the elastic restoring force and tensile strength are improved, thereby providing excellent elastic support effect.

According to the present invention, a plurality of lengthwise moving yarns in parallel are woven in a width direction by a connecting yarn, wherein two yarns are wound in a spiral direction outside the core member, the first yarn is wound in a leftward spiral direction , And the second yarn is wound in the right-hand spiral direction so that the first yarn and the second yarn are wound so as to cross each other in an X-shape from the inside and the outside.

The core material of the present invention is formed of an elastic rubber material having elasticity, and the first and second raw yarns are formed of a polypropylene yarn.

The resilient supporting band for furniture according to the present invention is formed by winding a long string of a band made by weaving a plurality of road moving pieces into a connecting yarn by winding the yarn outside the core in the spiral direction twice instead of once, And therefore, the elastic yarn does not lose its elasticity even after long use, and the elastic restoring force and tensile strength are improved to provide excellent elastic support effect.

As a result, the quality and durability of the furniture can be maintained for a long time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The resilient support band 2 for furniture according to the present invention is constructed such that a plurality of long-distance moving members 3 arranged in parallel as shown in Figs. 2 to 5 are woven in the width direction by the connecting yarns 6.

In particular, the lengthwise moving member 3 is configured to have an elastic supporting force and a restoring force, which are important functions of the band.

That is, the lengthwise moving unit 3 winds the two yarns in the spiral direction outside the core 4, the first yarn 5a is wound in the leftward spiral direction and the second yarn 5b is wound in the rightward spiral direction And the first yarn 5a and the second yarn 5b are wound so as to cross each other in an X-shape from the inside and the outside.

Preferably, the core 4 is formed of an elastic rubber material having elasticity, and the first and second yarns 5a and 5b are formed of polypropylene yarn. However, the first and second yarns 5a and 5b may be formed of various other materials to be.

As the unexplained reference numerals, 10 denotes a frame and 20 denotes a mattress.

Hereinafter, the operation and operation of the present invention will be described.

The elastic support band (2) for furniture according to the present invention is manufactured by weaving a plurality of lengthwise guides (3) arranged in parallel by a connecting yarn (6) in a width direction. The lengthwise guides (3) The first yarn 5a and the second yarn 5b formed of polypropylene yarn are wound in the spiral direction on the outer side of the yarn 4 instead of winding the single yarn in the spiral direction as in the conventional case.

The first yarn 5a is wound outside the core 4 in the left helical direction and the second yarn 5b is wound on the outer side of the core 4 outside the first yarn 5a Direction, and the first yarn 5a and the second yarn 5b are wound so as to cross each other in an X-shape from the inside and the outside.

The resilient supporting band 2 for furniture according to the present invention is installed on a frame 10 such as a bed, a sofa, a chair, or the like, so as to elastically support the upper mattress 20.

In this process, the resilient support band 2 for furniture according to the present invention is elastically supported effectively by the extension and retraction of the lengthwise moving member 3 against the load acting on the mattress 20.

At this time, since the outer side of the core 4 is helically wound and held in the shape of an X so that the first yarn 5a and the second yarn 5b intersect with each other, The elongation and returning operation of the lengthwise moving member 3 is smoothly performed as compared with the spiral winding.

That is, in the state where the first yarn 5a is spirally wound around the core member 4 and the second yarn 5b is wound on the outer side of the first yarn 5a, Shaped yarn in a spiral direction opposite to the direction in which the core yarn and the first yarn are wound together so as to firmly hold the core yarn and the first yarn firmly, Is smoothly performed.

Thus, the lengthwise moving member 3 is smoothly extended and retracted even after long use, and the restoring force and the tensile strength are improved more than the conventional ones without losing the elastic force against the load acting on the mattress 20, Is provided.

Therefore, the present invention is characterized in that a lengthwise movement of a band which is manufactured by weaving a plurality of long-distance moving yarns into a connecting yarn is formed by winding the yarn outside the core member twice, not once but in a spiral direction, wherein the first yarn and the second yarn cross each other in an X- Therefore, the elastic yarn does not lose the elasticity even after long use, and the elastic restoring force and tensile strength are improved, so that the elastic supporting effect is excellent and the quality of the furniture is improved.
