  The main problem to be solved by the present invention is that, in a bed mattress constructed using this type of pocket coil or open coil, the coil construction can be easily combined with the outer material and the padding, and further separated. In addition, it is possible to rationally strengthen the combined state.

In order to achieve the above object, in the present invention, a bed mattress is provided with an assembly of pocket coils or open coils, and a border wire that borders a horizontal surface portion of the assembly having a rectangular outline. Bed mattress mainly composed of coil construction,
A clip for the border wire;
A retainer that clamps both or one of the flange-shaped dough connected to the edge of the outer surface covering the horizontal surface portion between the clip and the edge of the filling that is stored between the outer surface and the horizontal surface portion; Have
The clip has a horizontal portion in contact with the horizontal surface portion, and a vertical portion extending in a height direction from an outer end portion of the horizontal portion, and a bent portion between the horizontal portion and the vertical portion. A clamp part that receives the border wire inside by bending of the inner side of the bending part, and a head part at the protruding end of the vertical part,
The retainer was a channel-like body that received the head of the clip inside while elastically expanding the entrance.

The clip is coupled to the assembly side by fastening a border wire to the clamp part by the elastic deformation, and the edge of the flange-like dough and the filling between the head of the vertical portion of the clip and the retainer. The entrance of the retainer is elastically expanded from the state where the part is interposed, and the head is received in the retainer to be coupled to the flange-like dough and the filling side. The side is integrated. Such coupling can be appropriately performed without using a special tool or the like, and a mattress mainly composed of coil construction can be easily manufactured. In the use state of the mattress, the force in the direction of pulling the edge of the flange-shaped dough and the filling in the height direction is applied, but the head is formed at the protruding end of the vertical portion of the clip. Therefore, as the force is applied, the retainer can more firmly hold the flange-shaped dough and the edge of the filling with the head. In addition, the clip and the border wire are joined by a special tool by pulling the clip in the direction in which the border wire is pulled out from the clamp portion with the force that causes the elastic deformation of the clamp portion to the same extent as when the border wire is received. It can be canceled without using. In addition, when the clip is connected to the flange-shaped dough and the filling side, the head is pulled out of the retainer by pulling the retainer with a force generated by the retainer to the same extent as when the retainer receives the head. By doing so, it can be released without using a special tool. That is, the coil construction can be easily separated from the outer material and the padding, and the clip can be easily separated therefrom.

  In a preferred embodiment of the present invention, an angle formed between the lateral portion and the longitudinal portion on the inner side of the bent portion of the clip is a right angle or an acute angle slightly smaller than the right angle. One.

  In addition, it is preferable that a protruding portion is formed at a position in the middle of the clip in the left-right direction between the clamp portion and the head portion in the longitudinal portion of the clip. One of them. In this case, the flanged fabric and the edge of the filling can be firmly sandwiched between the retainer and the vertical portion of the clip in a state where the protrusion is positioned in the retainer, and the protrusion protrudes into the retainer. By sliding the retainer to the position where the part is not positioned, using the longitudinal part of the clip as a guide, it is possible to create a state in which the head can be easily pulled out from the retainer. Release can be made smoother.

  In the bed mattress according to the present invention, the coil construction and the outer material and the padding can be firmly coupled without using a special tool or the like by the two members of the clip and the retainer. This can be done easily without requiring special tools.

   Hereinafter, typical embodiments of the present invention will be described with reference to FIGS. The mattress for betting according to this embodiment is configured by gathering together a plurality of pocket coils P, P,..., That is, an aggregate Mb of such pocket coils P as a main body.

  Specifically, in this embodiment, as shown in FIG. 1, a plurality of pocket coils P, P... Are arranged in parallel to constitute the assembly Mb. The pocket coil P is stored in the pocket in a state where the compression coil spring Pa is compressed. In the illustrated example, the pocket coil P is continuously provided with a plurality of pockets containing the compression coil springs Pa in a state where the pockets are connected on the side of the compression coil spring Pa containing the adjacent pockets. Become. The pocket coil P is formed on the cylindrical fabric Pb while storing the compression coil springs Pa one by one in the cylindrical fabric Pb, typically a nonwoven fabric Pb made of synthetic resin fibers. On the other hand, it forms by forming the welding part (illustration is abbreviate | omitted) along the width direction, respectively on both sides of the compression coil spring Pa one by one. That is, the pocket coil P is divided into a plurality of spaces (i.e., a plurality of welded portions provided with a space between the welded portions adjacent to each other in the length direction with respect to the cylindrical cloth Pb (that is, One compression coil spring Pa is stored in each of the pockets. Typically, each compression coil spring Pa has the same size and shape, and each pocket has substantially the same size. The adjacent pockets are connected at the welded portion. Each compression coil spring Pa accommodated in each pocket has a spring winding axis along the width direction of the cylindrical fabric. In the example shown in FIG. 1, a plurality of pocket coils P, P... Configured as described above are arranged in parallel so that the spring winding central axis of the compression coil spring Pa is along the thickness direction of the mattress configured. The assembly Mb is formed by adhering adjacent pocket coils P to each other on their side surfaces.

  Such an assembly Mb has a rectangular outline formed by the upper horizontal plane part Mba having a quadrangular outline constituted by the upper ends of the collected pocket coils P and a square constituted by the lower ends of the collected pocket coils P. A thickness side surface portion between the upper and lower horizontal surface portions Mba, Mba, which is constituted by a lower horizontal surface portion Mba having a shape and a side surface of the pocket coil P positioned outside the collected pocket coils P. Mbb.

  The upper horizontal surface portion Mba and the lower horizontal surface portion Mba of the aggregate Mb are each edged by a border wire Ma. The border wire Ma is typically made of a metal wire, and has a quadrangular frame shape along the outline of the horizontal surface portion Mba. The border wire Ma is fastened to the pocket coil P located outside the pocket coil P constituting the assembly Mb by the metal ring R. That is, the open end of the metal ring R is pierced into the fabric Pb in a state where the border wire Ma is passed inside the C-shaped metal ring R, and one compression coil spring Pa is inserted into the metal ring R. The border wire Ma is attached to the assembly Mb by bending the metal ring R and closing the open portion of the metal ring R from the state where the portion is positioned. The assembly Mb and the border wire Ma attached to the assembly Mb in this way constitute a coil construction M that is the main body of the mattress.

  In the coil construction M, the upper and lower horizontal surface portions Mba and Mba of the aggregate Mb are each covered with a surface material Sa. Moreover, the filling Sb is stored between this surface material Sa and the horizontal surface part Mba of the assembly Mb. Further, the thickness side surface portion Mbb of the aggregate Mb is covered with a cloth called a border Sc. The upper edge portion of the border Sc is fixed to the edge portion of the upper surface material Sa, and the lower edge portion of the border Sc is fixed to the edge surface of the lower surface material (not shown) to form a mattress.

  The surface material Sa is also referred to as a panel or the like. In the illustrated example, the surface material Sa is configured by quilting. A flange-shaped cloth Sa 'is provided on the edge of the outer material Sa over the entire circumference. In the illustrated example, the flange-shaped cloth Sa ′ is integrated with the inner surface located on the horizontal surface portion Mba side of the surface material Sa, and this aggregate is formed when the horizontal surface portion Mba of the assembly Mb is covered with the surface material Sa. The thickness of the Mb is extended outward from the side surface portion Mbb.

The filling Sb typically has a mat shape, and a plastic foam material or a nonwoven fabric is used. In the illustrated example, one filling Sb is stored between the surface material Sa and the horizontal surface portion Mba of the assembly Mb, but two or more fillings Sb may be stored.

  The mattress according to this embodiment includes a clip 1 for the border wire Ma, a flange-shaped cloth Sa ′ connected to the edge of the surface material Sa covering the horizontal surface portion Mba between the clip 1 and the surface material Sa. It has the retainer 2 which clamps both or any one of the edge part of the filling Sb accommodated between the said horizontal surface part Mba.

  The clip 1 includes a lateral portion 10 that contacts the horizontal surface portion Mba, and a longitudinal portion 11 that extends in the height direction z from an outer end portion 10c of the lateral portion 10. A clamp portion 13 that receives the border wire Ma by elastic deformation is provided inside the bent portion 12 between the facing portion 11 and a head portion 11a at a protruding end portion of the vertically facing portion 11.

  On the other hand, the retainer 2 is a channel-like body that receives the head portion 11a of the clip 1 inside while elastically expanding the entrance 23.

The clip 1 is joined to the assembly Mb side by fastening the border wire Ma to the clamp portion 13 by the elastic deformation, and the clip 11 is connected to the head portion 11a of the longitudinal portion 11 of the clip 1 and the retainer 2. The flange-shaped fabric Sa ′ and the flange-shaped fabric Sa ′ are received by elastically expanding the entrance 23 of the retainer 2 from the state where the flange-shaped fabric Sa ′ and the edge of the filling Sb are interposed therebetween, while elastically expanding the entrance 11 of the retainer 2. It is combined with the filling Sb side, whereby the assembly Mb side, the flange-shaped cloth Sa ′ and the filling Sb side are integrated. Such coupling can be appropriately performed without using a special tool or the like, and a mattress mainly composed of the coil construction M can be easily manufactured.

  In the use state of the mattress, a force in a direction of pulling the edges of the flange-shaped dough Sa ′ and the filling Sb in the height direction z is applied. As the force is applied, the retainer 2 strengthens the edge of the flange-shaped cloth Sa ′ and the filling Sb that are formed between the head 11a as the force is applied. It can be made to pinch. That is, when such a force is applied, the retainer 2 is applied with a force in a direction around the head 11a in the direction indicated by the symbol F in FIGS. 3 and 4 with the head 11a as the center. Therefore, the clamping force between the head portion 11a and the retainer 2 on the outside of the vertical portion 11 can be increased as the above force is applied.

  Further, the clip 1 and the border wire Ma are coupled by pulling the clip 1 in the direction in which the border wire Ma is pulled out from the clamp portion 13 by the force that causes the elastic deformation of the clamp portion 13 to the same extent as when the border wire Ma is received. By doing so, it can be released without using a special tool. Further, the clip 1 is connected to the flange-shaped cloth Sa ′ and the filling Sb side by pulling the retainer 2 with a force that causes the retainer 2 to undergo the same elastic deformation as when the retainer 2 receives the head 11a. By removing the head 11a from the retainer 2, it can be released without using a special tool. That is, the coil construction M can be separated from the surface material Sa and the filling Sb, and the clip 1 can be easily separated therefrom.

  Typically, the coupling is performed using two or more clips 1 at each side of the border wire Ma having the rectangular frame shape. In the illustrated example, one retainer 2 is combined with one clip 1. Further, the dimension of the clip 1 in the left-right direction x (the direction along the length direction of the border wire Ma) is approximately twice the dimension of the retainer 2 in the left-right direction x. However, the size of the clip 1 in the left-right direction x may be further increased so that one clip 1 is combined with two or more retainers 2.

  In the example shown in the figure, both the horizontal portion 10 and the vertical portion 11 of the clip 1 have a plate shape. In addition, on the inner side of the bent portion 12 of the clip 1, the angle formed by the lateral portion 10 and the vertical portion 11 is an acute angle that is slightly smaller than a right angle. The outer side of the bent portion 12 is a rounded surface 12a, and the outer surface of the lateral portion 10 and the outer surface of the vertical portion 11 are continuous via the rounded surface 12a. Further, the inside of the bent portion 12 is also a rounded surface 12b. A rib-like portion 11b is formed on the inner surface side of the laterally facing portion 10 in the left-right direction x at a position between the bent portion 12 and the head portion 11a. The rib-like portion 11b is curved such that the side directed toward the bent portion 12 is the curved inner side. The distance between the protruding end 11c of the rib portion 11b and the inner surface of the lateral portion 10 is slightly smaller than the diameter of the border wire Ma, while being formed between the bent portion 12 and the rib portion 11b. The tubular space 13a to be formed is substantially equal to the diameter of the border wire Ma. In the illustrated example, the border wire Ma is placed in the space 13a from between the protruding end 11c of the rib-like portion 11b and the laterally facing portion 10 while causing the elastic deformation to widen the distance between the two. It comes to hold. That is, in the illustrated example, the clamp portion 13 is constituted by the bent portion 12 and the rib-like portion 11b.

  In the example shown in the drawing, the dimension of the lateral portion 10 in the inner and outer direction y is larger than the dimension of the longitudinal portion 11 in the height direction z. Further, the inner end portion 10a of the lateral portion 10 located inward of the border wire Ma is bent to form a rising portion 10b that protrudes toward the same side as the side from which the vertical portion 11 extends. Yes. The protruding dimension of the rising portion 10b is smaller than the dimension of the vertical portion 11 in the height direction z. The lateral portion 10 comes into contact with the horizontal surface portion Mba of the coil construction M at the rising portion 10b in a state where the border wire Ma is held by the clamp portion 13.

  In the illustrated example, the head portion 11a is one surface of a band plate-like body having a length in the left-right direction x of the clip 1, and the vertical portion 11 protrudes between the outer end and the inner end thereof. By connecting the end portions integrally, the protruding end portion is formed.

Further, in this embodiment, between the clamp portion 13 and the head portion 11a in the longitudinal portion 11 of the clip 1 and in the middle of the clip 1 in the left-right direction x, A protruding portion 11d is formed. In the illustrated example, the projecting portion 11d has one end integrally connected to the rib-shaped portion 11b constituting the clamp portion 13 and the other end integrally connected to the head portion 11a on the inner surface side of the vertical portion 11. It is constituted by the vertically oriented ribs 11e. Between the protruding end of the vertical rib 11e and the head 11a, that is, the inner end of the band plate-like body, an interval is formed which becomes an engagement margin 14 to be described later of the retainer 2.

  On the other hand, the retainer 2 has a shape having the same cross section along the inner and outer direction y at any position in the left-right direction x, and can be appropriately generated from synthetic resin by extrusion molding. .

  In the illustrated example, the retainer 2 includes a substrate 20, an outer rising portion 21 rising from the outer end of the substrate 20 on one surface side of the substrate 20, and an inner side rising from the inner end of the substrate 20 on the one surface side of the substrate 20. And a rising portion 22. Further, the protruding end of the outer rising portion 21 is formed with a claw portion 21a protruding toward the inner rising portion 22 side, and the protruding end of the inner rising portion 22 protrudes toward the outer rising portion 21 side. A claw portion 22a is formed. The distance between the outer rising portion 21 and the inner rising portion 22 is slightly larger than the dimension in the inner and outer direction y of the head portion 11a of the clip 1. On the other hand, the distance between the claw portions 21a and 22a is slightly smaller than the dimension in the inside / outside direction y of the head portion 11a of the clip 1, and the entrance 23 of the retainer 2 is between the claw portions 21a and 22a. It has become.

  The clamp portion 13 is arranged so that the lateral portion 10 of the clip 1 is in contact with the horizontal surface portion Mba of the assembly Mb and the longitudinal portion 11 is located outside the thickness side surface portion Mbb of the coil construction M. From the state in which the border wire Ma is held, the inlet 23 of the retainer 2 is applied to the outer surface portion of the head portion 11a with a predetermined force with both or either of the flanged fabric Sa ′ and the edge of the filling Sb in between. And the retainer 2 side is elastically deformed so as to widen the entrance 23, and the head 11a is received in the retainer 2 together with the flange-shaped cloth Sa 'and / or the edge of the filling Sb. It is like that. Then, by the elastic return of the retainer 2 at the receiving end position, the claw portion 21a of the outer rising portion 21 of the retainer 2 uses the outer end of the band plate-like body constituting the head portion 11a of the clip 1 as the engagement margin 14. While engaging, the claw portion 22a of the inner rising portion 22 of the retainer 2 has an engagement margin 14 between the inner end of the band plate-like body constituting the head portion 11a of the clip 1 and the protruding end of the vertical rib 11e. It is designed to engage with this. As a result, the assembly Mb side, the flange-shaped cloth Sa ′, and the filling Sb side are integrated via the clip 1. In the illustrated example, a ridge 24 extending in the left-right direction x is formed on the inner surface of the substrate 20 and immediately below the entrance 23, and the head 11a of the clip 1 is placed in the retainer 2 as described above. In this state, the ridge 24 is projected to the edge of the flange-shaped cloth Sa ′ and the filling Sb under the head 11a. In the example shown in the figure, the clip 1 is attached to the border wire Ma in a state where the edge of the sheeting Sd that is stuck to the horizontal surface portion Mba of the assembly Mb is stored in the clamp portion 13 of the clip 1. It is like that.

In a state where the mattress is used, when a force is applied to pull the edges of the flange-shaped fabric Sa ′ and the filling Sb in the height direction z, the retainer 2 has the head 11a in FIG. In FIG. 4, a force is applied to rotate around the head portion 11 a in the direction indicated by the symbol F, and the distance between the claw portion 21 a of the outer rising portion 21 of the retainer 2 and the outer end 11 a ′ of the head portion 11 a of the clip 1 is The flanged dough Sa ′ and the edge of the filling Sb are more firmly sandwiched between them.

  The head 11a is positioned in the retainer 2, but when the retainer 2 is slid in the left-right direction x using the vertical portion 11 of the clip 1 as a guide to a position where the vertical rib 11e as the protruding portion 11d is not positioned. Since a margin corresponding to the protruding dimension of the longitudinal rib 11e is generated between the head 11a and the retainer 2, the head 11a can be easily extracted from the retainer 2. In this way, from the state in which the retainer 2 is slid, the retainer 2 is pulled in a direction in which the head portion 11a is pulled out from the retainer 2, so that the entrance 23 is expanded again and the head portion 11a is pulled out from the retainer 2. Thus, the connection between the clip 1 and the flange-shaped dough Sa ′ and the filling Sb side can be smoothly released.

  By making the clip 1 and the retainer 2 into a plastic molded product, the elastic deformation characteristics can be easily and appropriately imparted to the portions that should have the elastic deformation characteristics.

  Of course, the present invention is not limited to the embodiments described above, but includes all embodiments that can achieve the object of the present invention.
