Description

  The present invention relates to a cushion structure, a cushion, and a method for manufacturing the cushion.

  When a person sits on a chair or lies on a bed, a cushion may be laid on the chair or bed. As a material constituting the cushion used in such a case, a material having elasticity is widely used. As a material of the cushion laid on the chair, for example, a polyurethane foam, a material combining a plurality of urethane foams having different densities, a polyester foam, and the like are frequently used. Also, futon cotton, chemical fibers (for example, polyester fibers, polyurethane fibers, etc.) are frequently used for the bed.

In the cushion having the elastic force as described above, a cushion having a large sinking depth when a load is applied has been proposed (Patent Document 1). The thing of patent document 1 is provided with the some hole part 101 penetrated from the upper surface to the lower surface in the seat surface 102 of the cushion 100, as shown in FIG. This makes it easier to sink the cushion around the place where the load is applied, thereby improving the cushioning property (sitting comfort). In addition to the one described in Patent Document 1, there is a type in which a sinking depth is increased by making a lattice-shaped cut or the like in the seating surface of the cushion.
JP-T-2001-514912

  The thing of the said patent document 1 has the seat surface of the cushion connected continuously in the horizontal direction. For this reason, when a load is applied locally, the part to which the load is applied sinks, and the vicinity of this part and, in some cases, the cushion end are affected (the pressing force is transmitted) and the part sinks in a chain. There is a case. That is, even if the range where the load is applied is small, the sinking range may be wide.

  As described above, when the cushion sinks in a wide range, the portion to which the load is applied is affected by a pulling force from the surroundings. For this reason, there existed a problem that the site | part to which the load was loaded was hard to sink. Further, when the load is removed, there is a problem that it takes a long time to restore since the restoration over a wide range is required.

  In view of the above problems, the present invention provides a cushion structure, a cushion, and a cushion that can be easily restored when a load is applied with a simple configuration and when the load is removed. A manufacturing method is provided.

  The cushion structure of the present invention is provided between an outer frame portion made of a pair of elastic materials disposed substantially in parallel with a predetermined interval, and is provided between the outer frame portions to allow elastic approach and separation of the outer frame portion. An interior portion made of an elastic material, and the interior portion has a plurality of block pieces formed with slit holes that are enlarged by applying a tensile force in a direction away from each other between the pair of outer frame portions along the stretch direction. The block aggregate is provided along the direction orthogonal to the expansion / contraction direction, and adjacent block aggregates are disconnected along the direction orthogonal to the expansion / contraction direction.

  According to the cushion structure of the present invention, the outer frame portion can be expanded and contracted via the interior portion, and can be elastically approached and separated, so the width direction (dimension between outer frame portions) is arbitrarily set. Can be used. In addition, since the block aggregates adjacent to each other along the direction orthogonal to the expansion / contraction direction are disconnected, the block aggregates adjacent to each other along the direction orthogonal to the expansion / contraction direction exhibit independent cushioning properties. . As a result, when a load is applied to one block aggregate, other block aggregates that are not loaded are not affected, so only the block aggregate loaded can be submerged locally. In addition, when restoring, it is only necessary to restore the sunk block aggregate. Furthermore, since the block pieces are continuously arranged along the extending and contracting direction, the number of block pieces can be arbitrarily set.

  The said cushion structure can be made into the state which the clearance gap in the direction orthogonal to an expansion-contraction direction and an expansion-contraction direction closely_contact | adheres in a free state.

  The said block piece can be made into a rhombus in planar view in the tension | tensile_strength provision state.

  The thickness dimension of the joint portion between the block pieces adjacent to each other along the extension / contraction direction can be made smaller than the thickness dimension of the block pieces.

  In the cushion of the present invention, the cushion structure according to each of the above inventions is fixed to a bottom plate made of a rectangular plate-shaped member in a state where the pair of outer frame portions are separated from the free state.

  According to the cushion of the present invention, the cushion component can be fixed to the bottom plate in a state where the pair of outer frame portions are separated from the free state, and the state where the cushion component is pulled can be maintained.

  Moreover, the cushion structure body which concerns on each said invention can hold | maintain the other cushion of this invention to a mounting surface part in the state which spaced apart a pair of outer frame part from the free state.

  According to another cushion of the present invention, it is possible to maintain a state in which the cushion component is pulled, and it is possible to directly fix the cushion structure to a site where the cushion is used.

  The method of manufacturing a cushion according to the present invention includes a pair of elastic members arranged substantially in parallel with a predetermined interval, and an inner frame arranged between the outer frame portions to allow elastic approach and separation of the outer frame portions. A method of manufacturing a cushion including an interior portion made of an elastic material, wherein a plurality of vertical slits and horizontal slits are formed in a rectangular material, and then opposite outer side portions of the rectangular material are separated from each other By pulling in the direction and maintaining this tensioned state, the outer side portion becomes the outer frame portion, and a cushion in which the interior portion is formed between the outer frame portions is formed.

  Another method of manufacturing the cushion according to the present invention includes an outer frame portion made of a pair of elastic materials disposed substantially in parallel with a predetermined interval, and a pair of outer frame portions, and an interior of the outer frame portion. A method of manufacturing a cushion including an interior part made of an elastic material that allows elastic approaching / separation of a part, and a pair of outer vertical slits arranged substantially parallel to a predetermined interval in a rectangular material, The inner vertical slit disposed substantially parallel to the outer vertical slit between the pair of outer vertical slits, and the horizontal slit connecting the longitudinal intermediate portions of the pair of outer vertical slits via the inner vertical slit. A first slit assembly and a second slit assembly provided between adjacent first slit assemblies and having a slit substantially parallel to the vertical slit interposed between the vertical slits of the first slit assembly are formed. After the rectangular material phase By pulling the outer side portions facing away from each other and maintaining this tensioned state, the outer side portion becomes the outer frame portion, and a cushion is formed in which the interior portion is formed between the outer frame portions. Is.

  According to the cushion manufacturing method of the present invention, after forming a plurality of slits in a rectangular material, the opposing outer side portions of the rectangular material are pulled in directions away from each other, and the tensioned state is maintained. By doing so, the cushion can be configured.

  Since the cushion structure of the present invention can be used by arbitrarily setting the width direction (dimension between outer frame portions), when using this cushion structure for a cushion, the size and shape of the portion to be used Can be used in correspondence. For this reason, cushions of various sizes can be provided by one type of cushion structure, and the cost can be reduced for the user. In addition, the outer frame portion and the interior portion are made of an elastic material and have excellent cushioning properties. Also, since only the block aggregate loaded can be sunk locally, the part loaded is easy to sink, and when restoring, only this block aggregate needs to be restored. Easy to restore early. Furthermore, since the number of block pieces can be set arbitrarily, by increasing or decreasing the number of block pieces, the width direction (dimension between outer frame parts) can be set arbitrarily, and the outer frame part The amount of expansion and contraction can be adjusted. The block piece has a slit hole that expands by applying a tensile force in the direction in which the interior portion and the pair of outer frame portions are separated from each other. In addition, it exhibits elasticity, excellent deformability, and high quality cushioning properties.

  When the cushion structure is in a state where the cushion structure is in a free state and the gap in the direction perpendicular to the expansion / contraction direction is in close contact with the cushion structure, it is possible to reduce the size and improve the handleability.

  Since the block piece can be formed in a rhombus in a plan view in a state where a tensile force is applied, the seating surface of the cushion structure has a mesh shape. Thereby, even if an outer frame part is pulled, the ratio which a cushion constituent occupies for a seat surface can be made sufficient, and the function of the cushion constituted by this cushion constituent can be exhibited.

  If the thickness dimension of the joint portion between adjacent block pieces along the extension / contraction direction is made smaller than the thickness dimension of the block pieces, it becomes even easier to sink.

  The cushion formed by fixing the cushion structure according to each of the above inventions to a bottom plate made of a rectangular plate-shaped member can be stably placed on a use site such as a chair and is easy to carry. , The convenience can be improved. Moreover, the cushion formed by holding | maintaining the cushion structure which concerns on each said invention in a mounting surface part can be fixed stably, without shifting | deviating from a use site | part.

  According to the cushion manufacturing method of the present invention, the cushion according to the present invention can be formed easily and at low cost. In particular, cushions of various sizes and thicknesses can be easily manufactured by selecting the size and thickness of the rectangular material. Further, by changing the material of the rectangular material, it is possible to easily manufacture a cushion having different elasticity.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  As shown in FIG. 4, the cushion of the present invention is used by being placed on a seating surface of a chair 16 or the like. This cushion includes a cushion component 1 having elasticity, a bottom plate 2 that fixes the cushion component 1, and a cover 4 made of a cloth bag that surrounds the cushion component 1 and the bottom plate 2.

  The cushion structure 1 is made of elastic urethane, and as shown in FIGS. 1 and 2, a pair of outer frame portions 6a and 6b, and an interior portion 3 that is installed between the outer frame portions 6a and 6b, It has. The outer frame portions 6a and 6b have a rectangular flat plate shape, and one outer frame portion 6a and the other outer frame portion 6b are arranged substantially in parallel with a predetermined interval.

  The interior part 3 is configured by arranging the block pieces 9 having a rhombus in a plan view in a direction along the pair of outer frame parts 6a and 6b and a direction along the direction orthogonal to the pair of outer frame parts 6a and 6b. A plurality of block pieces 9 (six in the illustrated example) are connected and arranged along the direction orthogonal to the outer frame part 6 via the joint part 17, and one block piece 9 is connected to the block piece 9. A block aggregate 10 is formed. A plurality of block assemblies 10 (four rows in the illustrated example) are formed along the outer frame portions 6a and 6b, and adjacent block assemblies 10 are not connected. The block piece 9 has a rhombus in plan view, and has an abacus shape having variable curved surface portions 13a, 13b, 13c, and 13d that expand from the both end surfaces 12a and 12b toward the center, and a slit hole 7 provided in the center portion. Have

  Therefore, between the end 12a of the block piece 9 in one block aggregate 10 and the end 12b facing the end 12a in the block piece 9 of the block aggregate 10 adjacent to the block aggregate 10. Thus, the first gap 14 is formed. Further, in the curved surface portion 13 a of the block piece 9 of one block aggregate 10, the curved surface portion 13 b of the block piece 9 adjacent thereto, and the block piece 9 of the block aggregate 10 adjacent to this block aggregate 10 A second gap 15 is formed by the curved surface portions 13c and 13d facing the curved surface portions 13a and 13b. Further, a third gap 8 is formed by the inner end surface of one outer frame portion 6a and the curved surface portions 13a and 13c of the respective block aggregates 10 adjacent to the outer frame portion 6a, and the other outer frame portion 6b. A third gap 8 is formed by the inner end face of each and the tapered faces 13b and 13d of the respective block assemblies 10 adjacent to the outer frame portion 6b. The first gap 14, the second gap 15, and the third gap 8 continuously form a gap 5 in a direction orthogonal to the outer frame portions 6 a and 6 b. As a result, the respective block aggregates 10 are independent from each other through the gap 5.

  The bottom plate 2 is a rectangular plate-shaped member made of urethane, and is fixed by bringing the upper surface of the bottom plate 2 and the lower surface of the cushion material 1 into contact with each other. In this case, the bottom plate 2 and the cushion material 1 are fixed with an adhesive, but may be fixed with a hook-and-loop fastener or the like.

  Next, a method for manufacturing the cushion will be described. First, as shown in FIG. 3, a first slit assembly 56 and a second slit assembly 57 are formed. The first slit aggregate 56 is an aggregate of the outer vertical slit 52, the inner vertical slit 55, and the horizontal slit 54. The second slit assembly 57 is an assembly of slits 53. That is, a pair of outer vertical slits 52 are formed in the rectangular material 50 so as to penetrate from the upper surface to the lower surface and are arranged substantially in parallel with a predetermined interval. Then, an inner vertical slit 55 is formed between the pair of outer vertical slits 52 and 52 so as to be substantially parallel to the outer vertical slit 52. A lateral slit 54 is formed to connect the intermediate portion in the longitudinal direction of the outer vertical slit 52 via the inner vertical slit 55. Further, the slit 53 is disposed between the adjacent first slit assemblies and is interposed between the vertical slits of the first slit assembly 56 to form a slit 53 substantially parallel to the vertical slit. Thus, the cushion structure 1 is formed by forming the first slit assembly 56 and the second slit assembly 57 in the rectangular material 50.

  The outer side 51 of the cushion structure 1 formed by the method as described above is pulled in a direction away from each other (direction perpendicular to the longitudinal slits 52 and 55 and the slit 53), and this tensioned state is maintained. In the state, the bottom plate and the lower surface of the rectangular material are fixed with an adhesive. In this case, the slits 52, 53, 54, 55 are enlarged, the first gap 14 is formed by the horizontal slit 54, the second gap 15 is formed by the inner vertical slit 55 and the horizontal slit 54, and the outer side A third gap is formed by the vertical slit 52 and the horizontal slit 54, and the slit hole 7 is formed by the slit 53 of the second slit assembly 57.

  Then, the cushion structure 1 and the bottom plate 2 are surrounded by a cover 4 made of cloth or the like.

  Thus, in the present invention, the cushion can be formed easily and at low cost. In particular, by selecting the size and thickness of the rectangular material 50, cushions of various sizes and thicknesses can be easily manufactured. Further, by changing the material of the rectangular material 50, it is possible to easily manufacture a cushion having different elasticity.

  Since the cushion constituent body 1 of the present invention can be used by setting the width direction (dimension between outer frame portions) arbitrarily, when using the cushion constituent body 1 for a cushion, It can be used according to the shape. For this reason, cushions of various sizes can be provided by one type of cushion structure 1, and the cost can be reduced for the user. Moreover, the outer frame portion 1 and the interior portion 3 are made of an elastic material and are excellent in cushioning properties. In addition, since only the block aggregate 10 to which the load is applied can be sunk locally, the portion to which the load is applied is likely to sink, and when restoring, only the block aggregate 10 is restored. Good, easy to restore early. Furthermore, since the number of the block pieces 9 can be arbitrarily set, the width direction (dimension between the outer frame portions) can be arbitrarily set by increasing or decreasing the number of the block pieces 9 and the outer frame. The amount of expansion / contraction of the parts 6a and 6b can be adjusted. Since the block piece 9 is formed with a slit hole 7 that expands by applying a tensile force in the direction in which the interior portion 3 and the pair of outer frame portions 6a and 6b are separated from each other, the elasticity of the interior portion itself and the slit hole 7 are formed. As a result, excellent shrinkability and elasticity are exhibited, the deformability is excellent, and a high-quality cushioning property is exhibited. In the free state, the expansion / contraction direction and the gap in the direction orthogonal to the expansion / contraction direction are in close contact with each other, so that compactness can be achieved and handling properties can be improved.

  In the free state, the cushion structure is in a state in which the expansion / contraction direction and the gap in the direction orthogonal to the expansion / contraction direction are in close contact with each other, so that the compactness can be achieved and the handleability can be improved.

  Since the block piece 9 has a rhombic shape in a plan view when a tensile force is applied, the seating surface of the cushion structure 1 has a mesh shape. Thereby, even if the outer frame part 6 is pulled, the ratio of the cushion component 1 to the seating surface can be made sufficient, and the function of the cushion constituted by the cushion component 1 can be exhibited. it can.

  The cushion formed by fixing the cushion structure 1 according to each of the inventions to the bottom plate 2 made of a rectangular plate-like member can be stably placed on a use site such as a chair and is easy to carry. Therefore, convenience can be improved.

  As another embodiment, as shown in FIGS. 5 and 6, the thickness dimension of the joint portion 17 connecting the block pieces 9 is smaller than the thickness dimension of the block pieces 9.

  Next, a method for manufacturing the cushion will be described. In the same manner as in the above-described embodiment, the bottom side 2 and the lower surface of the rectangular material are bonded with an adhesive while pulling the outer side portions 51 of the cushion structure 1 in a direction away from each other and maintaining this tensioned state. Fix it. Thereafter, the thickness of the joint 17 is made smaller than the thickness of the block piece 9 by scraping the joint 17 from the upper surface. That is, by forming the notch 18 on the upper surface of the joint 17, the thickness of the joint 17 is made smaller than the thickness of the block piece 9.

  As described above, if the thickness dimension of the joint portion 17 between the block pieces 9 adjacent to each other in the expansion / contraction direction is smaller than the thickness dimension of the block pieces 9, it is more likely to sink.

  Furthermore, as another embodiment, although not shown, the cushion structure 1 according to each of the inventions can be held on the placement surface portion. That is, a string body is sewed to the corner portion of the cushion constituting body 1, and the string body is fixed to a protrusion provided in the vicinity of the placement surface portion. Thereby, the shape which pulled the cushion structure 1 can be hold | maintained, and it can fix directly to the site | part which uses a cushion. For this reason, the cushion structure 1 can be stably fixed without shifting from the use site.

  As mentioned above, although it demonstrated per embodiment of this invention, this invention is not limited to the said embodiment, A various deformation | transformation is possible, for example, as a shape of the cushion structure body 1, it is not restricted to a square, A rectangle Or rhombus. Moreover, it may be placed not only on the chair but also on a bed or the like. The material of the cushion component 1 is not limited to urethane, and various materials such as rubber sponge and polyolefin foam can be employed. Further, the outer vertical slit 52 and the inner vertical slit 55 may be different in size. As the material of the bottom plate 2, various materials such as plastic and wood can be adopted as long as the cushion component 1 can be fixed. The size of the bottom plate 2 does not necessarily coincide with the cushion component 1. In addition, it is possible to variously change the fixing position and the fixing location of the cushion component 1 and the bottom plate 2. When using the cushion according to the present invention, the cover 4 may be omitted. Furthermore, the cover 4 is not limited to the case where the seat surface is horizontal, and is used as a backrest so that the seat surface is vertical. May be. When forming the first slit assembly 56, the formation order of the outer vertical slit 52, the inner vertical slit 55, and the horizontal slit 54 can be arbitrarily set, and after forming the second slit 57 first, The first slit 56 may be formed. The cushion component 1 may be used by being laminated in multiple stages, and in this case, the thickness and direction of each cushion component 1 may be different.

  The thickness dimension of the joint portion 17 can be arbitrarily set. In other words, the depth of the notch 18 may be a notch that is close to the vicinity of the bottom plate 2. Further, all of the joint portion 17 may be cut out and the cutout portion 18 may not be provided. The cutout portion 18 may be cut out from the lower surface of the cushion structure 1 or may be cut out from both the upper surface and the lower surface. Furthermore, in the said embodiment, although the junction part 17 was shaved after adhering the cushion structure 1 to the baseplate 2, you may scrape the joint 17 before adhering the cushion structure 1 to the baseplate 2.
