Abstract

PROBLEM TO BE SOLVED: To provide a cushion body having a further strengthened junction portion of a pedestal part to which an elastic support body connects, without impairing the characteristics of the elastic support body.SOLUTION: A cushion body 10 of the present invention includes: a pedestal part 2 having a surface; and a plurality of elastic support bodies 3 whose pressure receiving surface area for receiving loads almost reversibly changes on the basis of the size of the loads, with one end thereof adhered and fixed onto a surface 21 of the pedestal part 2 by an adhesive 4. In the pedestal part 2, at least a portion on a surface of the side to which the elastic bodies 3 are fixed, including a peripheral part thereof, are coated by a fibrous member 23 into which the adhesive 4 penetrates.

Description

  The present invention relates to a cushion body in which an elastic support body in which the area of a pressure-receiving surface that receives a load changes approximately reversibly depending on the magnitude of the load is bonded to a pedestal portion.

  Patent Document 1 discloses a mattress having a cushion body in which columnar members (elastic support bodies) are bonded to a pedestal portion at intervals. In Patent Document 2, a main body in which a columnar elastic body (elastic support) is inserted into a hole of an elastic foam in which a plurality of holes are formed is closed by a front surface member and a back surface member made of the elastic foam. A cushion body configured to be covered from both sides is disclosed.

  Since the mattress of Patent Document 1 is bonded using the anchor effect of the adhesive when the elastic support is bonded to the pedestal, the adhesive does not penetrate depending on the material of the pedestal, and the sufficient anchor effect May not be obtained. Further, even if a sufficient anchor effect is obtained, the pedestal portion is destroyed by the load in the surface direction (the direction in which the elastic support member is displaced laterally) to the elastic support member, and the elastic support member and It may come off from the pedestal together.

  Since the elastic support body of patent document 2 is covered with the elastic foam body, the characteristic of the elastic support body which has favorable cushioning properties may not fully be exhibited depending on the characteristic of an elastic foam body.

  The present invention has been made in view of the above situation, and should solve the problem of providing a cushion body in which the strength of the joint portion of the pedestal portion to which the elastic support body is joined is improved without impairing the characteristics of the elastic support body. Let it be an issue.

(1) The structural feature of the invention for solving the above problems is that the area of the pedestal having a surface and the pressure-receiving surface that receives the load changes substantially reversibly depending on the magnitude of the load, and the surface of the pedestal A plurality of elastic supports, one end of which is bonded and fixed with an adhesive, and
Have
The pedestal is a surface to which the elastic support is fixed, and at least a portion to which the elastic support is fixed and its peripheral part are covered with a fibrous member,
The adhesive is penetrating into the fibrous member.

  The above-described invention (1) can be added with the structure (2) and / or (3) described below.

  (2) The fibrous member is a cloth. The “cloth” may be “woven fabric” or “nonwoven fabric”.

  (3) The pedestal is a urethane foam.

  In the present invention, the pedestal is covered so that the fibrous member is positioned between the pedestal and the elastic support. Since the fibrous member is at least in a portion where the elastic support is fixed and its peripheral portion, the load applied to the elastic support is dispersed over a wide range of the pedestal through the fibrous member. That is, the load applied to the elastic support is distributed not only to the portion where the elastic support of the pedestal is bonded and fixed, but also to the entire portion covered with the fibrous member of the pedestal. Therefore, concentration of the load on the bonded portion between the elastic support and the pedestal portion can be prevented, the breakage of the pedestal portion of the bonded portion due to the load in the surface direction is suppressed, and the durability is improved. Further, since the adhesive for adhering / fixing the elastic support to the pedestal penetrates into the fibrous member, the adhesive strength of the elastic support is increased by the anchor effect.

It is a perspective view of the cushion body concerning an embodiment. It is a cross-sectional view of the cushion body according to the embodiment. It is a partial enlarged view of the cross section of the cushion body concerning an embodiment.

  Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the cushion body 10 includes a pedestal portion 2 formed of urethane or other elastic foam. The pedestal portion 2 has a rectangular plate shape, and an elastomer (elastic support) 3 is disposed on one side 21 thereof.

  As shown in FIGS. 2 and 3, the base portion 2 has a fabric laminate urethane 23 welded to one surface 241 of a base material 24 of urethane or other elastic foam. The fabric laminate urethane 23 is welded to the entire surface 21 of the pedestal 2, and the surface 21 of the pedestal 2 is the fabric laminate urethane 23.

  The fabric laminate urethane 23 has a composition different from that of the base material 24, and a fabric 232 as a fibrous member is fixed to one surface side 231a of the urethane 231 by frame lamination. The laminated fabric may be a woven fabric or a non-woven fabric. The size of the eyes on the fabric is not particularly limited, but it is desirable to have a size that allows the adhesive to penetrate easily. Then, it is desirable that the surface of the portion where the elastomer 3 is bonded to the pedestal portion 2 is so rough that the fibers are present at such a density that a large number of fibers can be juxtaposed. Furthermore, instead of the fabric, a plurality of fibers may be placed as they are. In particular, it is desirable from the viewpoint of stress dispersion that the fibers are arranged so that the orientation of the fibers is not a single direction but a plurality of directions. Therefore, it is preferable to employ the fabric as described above as the fibrous member.

  The elastomer 3 reversibly changes the area of the pressure-receiving surface that receives a load depending on the magnitude of the load, has elasticity (hardness) different from that of the pedestal 2, and one end 31 is bonded to the pedestal 2 by the adhesive 4. It is fixed. The elastomer 3 is a composite of a resin and oil obtained by impregnating an elastomer with oil.

  The adhesive 4 is not particularly limited. For example, a material obtained by dissolving almost the same material as that of the elastomer 3 with a solvent can be used, and when the material is fixed, the material is firmly bonded and fixed to the elastomer 3. Further, it may be composed only of the solvent without containing a solid content, and the material constituting the elastomer is dissolved by being brought into contact with the elastomer 3 to act as an adhesive. The adhesive 4 penetrates to the inside of the fabric laminate urethane 23 through the fabric 232 and is fixed in an anchor shape.

  The cushion body 10 of the present embodiment can use a configuration in which not only one elastomer 3 but also a plurality of the elastomers 3 are distributed in the spreading direction of the surface of the pedestal portion 2. At that time, it can be used as it is without being covered with other members, or can be used by covering the entire cushion body 10 with a cover member as required.

  As the cover member, a material having elasticity, flexibility, and stretchability that does not impair the characteristics of the elastomer 3 is desirable, like the base portion 2 and the elastic member 4. The cover member can be made of, for example, cloth, vinyl sheet, leather, soft urethane, or other elastic foam. As an example of use of the cushion body 10 of the embodiment, if there is one elastomer 3, a cushion for supporting an arm when using a mouse, a cushion, a mattress, a seat chair, The present invention is applicable to uses that require cushioning against external stress, such as pillows and back cushions.

  The cushion body of this embodiment can exhibit the following effects by having the above configuration. That is, in the cushion body 10 of the present embodiment, the fabric 232 covers the surface of the pedestal 2 so that the fabric 232 is positioned between the pedestal 2 and the elastomer 3. Since the fabric 232 is fixed not only to the portion to which the elastomer 3 is fixed, but also to the entire surface 21 of the pedestal 2, the load received by the elastomer 3 can be dispersed throughout the fabric 232 by the fibers of the fabric 232. it can.

  Since the fabric 232 is further laminated on the urethane 231, the load received by the elastomer 3 is received on the entire surface of the fabric laminate urethane 23, and local concentration of the load is prevented not only on the fabric laminate urethane 23 but also on the base material 24. can do. That is, the stress applied to the elastomer 3 is transmitted to the fibrous member before being transmitted to the pedestal portion 2. As a result, the applied stress can be dispersed over a wide range on the one surface side of the base material 24 (the pedestal portion 2) via the fibrous member, and as a result, the stress until the pedestal portion 2 is destroyed does not concentrate locally. become. Therefore, the strength of the bonded portion is improved.

  Moreover, since the adhesive 4 that bonds and fixes the elastomer 3 and the pedestal 2 penetrates the fabric 232 and the urethane 231, the adhesive strength of the elastomer 3 is strengthened by the anchor effect.

(Other embodiments)
The shape of the pedestal portion 2 is not particularly limited to a rectangular shape, and various shapes are possible along with the size according to the use of the cushion body 10. The shape of the elastomer 3 is not limited to a cylindrical shape such as an elliptical column or a polygonal column. Furthermore, the shape is not limited to a column shape, and a shape such as a cone shape or a truncated cone shape can also be adopted.

  Moreover, the arrangement | positioning and arrangement | positioning space | interval (pitch) of the elastomer 3 can be matched with the form to utilize. For example, if it is equally spaced over the entire pedestal portion 2, it can be arranged in a staggered manner.

  The cloth 232 may cover not only the one surface side 21 of the pedestal portion 2 but also all surfaces including the other surface side and the side surface side, or conversely, may cover only a part of the one surface side 21. When covering a part of the one side 21, the fabric as a fibrous member is sized so that the surface of the portion where the elastomer 3 is bonded to the pedestal portion 2 is generally covered or the surface is covered to the extent that it protrudes. 232 is disposed.

  In the embodiment described above, the form of the fabric laminate urethane 23 is used in order to dispose the fabric 232 as the fibrous member on the one surface side 21 of the pedestal portion 2. You may join to. Further, as a method of disposing the fabric 232 between the elastomer 3 and the pedestal 2, the surface of the elastomer 3 is replaced with the above-described method in which the fabric 232 is joined to the surface of the pedestal 2 and then the elastomer 3 is joined. It is also possible to bond the elastomer 3 (the one to which the cloth is bonded) so that the cloth contacts the pedestal portion 2 after the fibrous member such as the cloth is bonded.
