Abstract

There is provided a molded hook and loop fastener having at least one hook and loop fastener member which includes a flat plate-shaped base material and a plurality of engaging elements erected on a first surface of the base material in a center region in a width direction thereof, and configured to be integrated with a cushion body upon foaming of the cushion body. A flexible sheet-shaped resin material infiltration-blocking member is fixed to right and left side edge portions of the first surface of the base material and arranged along a longitudinal direction. Right and left support members are erected on the inside of fixation portions of the resin material infiltration-blocking member with respect to the base material, to support the resin material infiltration-blocking member. An upper end of the resin material infiltration-blocking member is configured to protrude above an upper end location of the support members.

First claim

The invention claimed is:

1. A molded hook and loop fastener having at least one hook and loop fastener member which comprises a flat plate-shaped base material and a plurality of engaging elements erected on a first surface of the base material in a center region in a width direction thereof, and configured to be integrated with a cushion body upon foaming of the cushion body, the molded hook and loop fastener comprising:
a flexible sheet-shaped resin material infiltration-blocking member fixed to right and left side edge portions, in the width direction, of the first surface of the base material and arranged along a longitudinal direction of the base material; and
right and left support members erected along the longitudinal direction of the base material at locations which are located on the inside of fixation portions of the resin material infiltration-blocking member with respect to the base material in the width direction, and configured to support the resin material infiltration-blocking member,
wherein an upper end of the resin material infiltration-blocking member is configured to protrude above an upper end location of the support members.

2. The molded hook and loop fastener according to claim 1 ,
wherein the molded hook and loop fastener is constituted of one hook and loop fastener member, and
wherein the resin material infiltration-blocking member comprises right and left first frame portions continuously arranged over the entire length of the base material in the longitudinal direction and second frame portions arranged along the width direction of the hook and loop fastener member on both ends of the hook and loop fastener member in the longitudinal direction and configured to connect the right and left frame portions with each other.

3. The molded hook and loop fastener according to claim 2 , wherein the first frame portions and the second frame portions are integrally formed with each other, and the resin material infiltration-blocking member is constructed of a single member.

4. The molded hook and loop fastener according to claim 2 , wherein the resin material infiltration-blocking member comprises a rectangular opening portion surrounded by the first frame portions and the second frame portions, and
wherein a dimension of the opening portion in the width direction is set to be smaller than a dimension between outer surfaces of the right and left support members and also a dimension of the opening portion in the longitudinal direction is set to be smaller than a dimension of the hook and loop fastener member in the longitudinal direction.

5. The molded hook and loop fastener according to claim 1 , wherein the sheet-shaped resin material infiltration-blocking member has a tubular shape obtained by connecting side edge portions of the resin material infiltration-blocking member to each other and is fixed to the right and left side edge portions of the base material.

6. The molded hook and loop fastener according to claim 1 , wherein the molded hook and loop fastener comprises a plurality of hook and loop fastener members and a flexible connection member for connecting the plurality of hook and loop fastener members along the longitudinal direction, and
wherein the resin material infiltration-blocking member comprises right and left first frame portions continuously arranged in the longitudinal direction over the plurality of hook and loop fastener members and second frame portions arranged in the width direction of the hook and loop fastener members to bridge between the adjacent hook and loop fastener members and configured to connect the right and left first frame portions with each other.

7. The molded hook and loop fastener according to claim 6 , wherein the first frame portions and the second frame portions are integrally formed with each other, and the resin material infiltration-blocking member is constructed of a single member.

8. The molded hook and loop fastener according to claim 6 , wherein the sheet-shaped resin material infiltration-blocking member has a constant width dimension over the entire length thereof in the longitudinal direction and is configured to cover the plurality of hook and loop fastener members over the entire width of the hook and loop fastener members in the width direction.

9. The molded hook and loop fastener according to claim 6 , wherein the connection member is configured to connect center portions, in the width direction, of the plurality of hook and loop fastener members to each other on a lower surface of the resin material infiltration-blocking member.

10. The molded hook and loop fastener according to claim 1 , wherein the resin material infiltration-blocking member is configured to extend outward in the width direction beyond right and left end edges of the base material.

11. The molded hook and loop fastener according to claim 1 , wherein the resin material infiltration-blocking member is constructed of a non-woven fabric.

12. The molded hook and loop fastener according to claim 1 , wherein the right and left support members are constituted of wall members integrally formed with the base material and intermittently or continuously erected thereon along a front and rear direction so that an engaging element region constituted of a plurality of engaging elements is interposed therebetween.

13. A method of manufacturing a cushion body, wherein the molded hook and loop fastener according to claim 1 is closely contacted with a fastener mount surface of a mold so that the first surface of the base material faces the fastener mount surface, and then foaming is performed so that the molded hook and loop fastener is integrated with the cushion body.

14. The method of manufacturing the cushion body according to claim 13 , wherein the fastener mount surface of the mold is formed as a single surface, wherein the method comprises closely contacting the molded hook and loop fastener with the single surface.
