Description

  The present invention relates to a cushion material and a chair, and more particularly to a cushion material capable of greatly expanding a load range in which a cushion effect can be obtained, and a chair using the cushion material.

  For example, cushion materials made of sponge, coil springs, etc. are widely used for chairs.

  The sponge as a cushioning material can adjust the flexibility of the cushion by changing its thickness, hardness, etc., while the coiled spring as a cushioning material can be changed by changing its length, hardness, etc. The flexibility can be adjusted.

  According to each of the cushion materials, a good cushion effect can be obtained within a predetermined load range, but there has been a problem that it is difficult to obtain a good cushion effect when an excessive load is applied.

  Accordingly, an object of the present invention is to provide a cushion material capable of greatly expanding a load range in which a cushion effect can be obtained, and a chair using the cushion material.

  The inventors of the present application have made intensive studies to obtain a cushion material capable of greatly expanding the load range in which the cushion effect can be obtained.

  As a result, a good cushion effect can be obtained if the rhombus wire mesh used in a fence or the like is configured to be bent in a loop shape in a direction perpendicular to the axis connecting the knitted portions and to apply a compressive load in the axial direction. The knowledge that the cushioning material which can expand a load range significantly can be obtained was acquired.

  The present invention has been made on the basis of the above findings, and is characterized by the following.

  According to the first aspect of the present invention, a rhombus wire mesh made of a plurality of wire rods knitted in a zigzag, knitted so that the mesh is a rhombus, is orthogonal to an axis line connecting the intersecting portions of the corrugation direction of the wire rod. It is characterized in that it is configured to be bent in a loop shape along the direction so that a compressive load is applied in the direction of the axis.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the rhombus wire mesh is bent into a cylindrical shape along a direction orthogonal to an axis connecting the intersecting portions. is there.

  The invention described in claim 3 is characterized in that, in the invention described in claim 2, the rhombus metal mesh is arranged concentrically.

  The invention according to claim 4 is characterized in that the cushion material according to any one of claims 1 to 3 is used.

  The invention according to claim 5 is characterized in that, in the invention according to claim 4, a seat portion is provided on the cushion material.

  The invention described in claim 6 is characterized in that, in the invention described in claim 4 or 5, the cushion material is placed on a base.

  According to the present invention, a rhombus wire mesh made of a plurality of wires bent in a zigzag, knitted so that the mesh becomes a rhombus, along a direction orthogonal to the axis connecting the intersections of the corrugation directions of the wires. When a compressive load is applied in the direction of the axis by bending it into a loop shape, a tensile force acts between the intersections of the adjacent wires, and this tensile force changes according to a wide load range and is compressed. When the load disappears, it will return to its original state.

  As a result, when the cushion material book of the present invention is used for, for example, a chair, the load range in which a good cushion effect can be obtained is significantly wider than that of the sponge or coil spring described above.

It is a perspective view which shows the cushion material of this invention. It is the elements on larger scale of FIG. It is a perspective view which shows another example of the cushioning material of this invention. It is a perspective view which shows the case where the cushion material of this invention is used for a chair. It is a front view which shows the case where the cushioning material of this invention is used for a chair. It is a front view which shows another example at the time of using the cushioning material of this invention for a chair.

  An embodiment of the cushion material of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a cushion material of the present invention, and FIG. 2 is a partially enlarged view of FIG.

  As shown in FIG. 1 and FIG. 2, the cushion material of the present invention is formed by corrugating the wire 1 with a rhombus wire mesh 2 formed of a plurality of wires 1 knitted in a zigzag shape. It consists of what was bent into the cylindrical shape along the direction orthogonal to the axis line 4 which connects the direction crossing part 3. FIG. The corrugating direction of the wire 1 is indicated by A in FIG.

  According to the cushion material of the present invention described above, when a compressive load is applied in the direction of the axis 4, a tensile force acts between the intersecting portions 3 of the adjacent wire materials 1, and this tensile force depends on a wide load range. When the compression load disappears, the original state is restored.

  As a result, by using the cushion material of the present invention for, for example, a chair, the load range in which a good cushion effect can be obtained is significantly wider than that of the sponge or coil spring described above.

  When the cushion effect needs to be further increased, as shown in FIG. 3, a plurality (three in this example) of rhombus metal mesh 2 may be arranged concentrically. In this case, the loop shape of the rhombus metal mesh 2 is not limited to a cylindrical shape. Further, the cushion effect can be adjusted by changing the material of the wire 1.

  When the cushion material of the present invention is used for a chair, as shown in FIGS. 4 and 5, a plate-like seat portion 5 is placed on top of the rhombus metal mesh 2.

  When the cushion material according to the present invention is used for a chair and the height of the diamond-shaped wire mesh 2 may be unstable, the diamond-shaped wire mesh 2 is placed on the base 6 as shown in FIG. Therefore, the height of the rhombus wire mesh 2 may be lowered.

  As described above, the cushion material of the present invention can be used as various cushioning members in addition to being used for a chair.

  As described above, according to the present invention, the rhombus wire mesh 2 composed of a plurality of wire rods 1 knitted in a zigzag shape, which is knitted so that the mesh is a rhombus, is connected to the intersecting portion 3 of the wire rod 1 in the wave direction. When a compressive load is applied in the direction of the axis 4 by bending it in a loop shape along the direction orthogonal to the axis 4 linking the two, a tensile force acts between the intersecting portions 3 of the adjacent wire rods 1. It changes according to a wide load range, and when there is no compressive load, it returns to its original state.

  As a result, by using the cushion material of the present invention for, for example, a chair, the load range in which a good cushion effect can be obtained is significantly wider than that of the sponge or coil spring described above.

  In addition, if the shape of the rhombus metal mesh 2 is a loop shape, it is not limited to a cylindrical shape, A square cylinder shape, an elliptic cylinder shape, etc. may be sufficient.
