Description

Cushion pad

Technical Field

The present utility model relates to a mat in which a lying part is constituted by a plurality of elastic members.

Background

Conventionally, there has been proposed a mat including a lying portion in which components of a predetermined shape formed of elastic members are aligned on a horizontal plane.

For example, patent document 1 (hereinafter also referred to as prior art 1) proposes a mattress bed provided with: a peripheral wall portion provided along the inside of the edge portion of the bed main body; and a lying part configured by orderly arranging and filling a plurality of rectangular elastic cushion members having the same height as the peripheral wall part in a space enclosed by the peripheral wall part. The plurality of elastic cushion members in prior art 1 are closely aligned and filled inside the peripheral wall portion to such an extent that the adjacent elastic cushion members abut each other. The packed elastic cushion members are fixedly installed so as not to be moved by fixing the installation unit such as a face fastener provided at the bottom of the bed main body.

Patent document 2 (hereinafter also referred to as prior art 2) discloses a bedding including a plurality of modules having elastic force and a frame provided with a plurality of spaces partitioned into the same size as the modules. The space provided in the frame is partitioned by a partition member having a sufficiently small thickness, and adjacent modules are arranged substantially without any gap.

Patent document 3 (hereinafter also referred to as "prior art 3") discloses a cushioning member in which a plurality of elastic small modules made of a sponge-like soft material such as foamed polyurethane are aligned on a substrate surface. In prior art 3, engaging holes are formed in the upper surface of the substrate at equal intervals, and engaging pins capable of engaging with the engaging holes are provided on the bottom surface side of the elastic small module, so that the elastic small module is detachably aligned on the substrate surface by engaging the engaging pins with the engaging holes. Here, the following description is made: since the adjacent elastic subassemblies are arranged at predetermined intervals, the elastic subassemblies as a whole are formed with fine grooves in a checkerboard shape around the elastic subassemblies, and the elastic subassemblies can be displaced independently of each other. The checkerboard is a grid of a board (board) for a board game of japan, and is divided into areas equally spaced in the longitudinal and transverse directions.

Problems to be solved by the utility model

The above-described prior art has the following problems.

That is, with the prior art 1, there is no gap between adjacent elastic cushion members, and therefore it is difficult for each elastic cushion member to deform independently. Similarly, in the prior art 2, since the thickness of the partition provided in the interior of the frame is small, there is substantially no significant gap between adjacent components. As a result, it is also difficult for prior art 2 for each component to deform independently.

Therefore, when the user lies on the pad or the like, the body sinking effect due to the elastic deformation of the elastic member cannot be sufficiently utilized.

In addition, the prior art 1 has the following problems: since there is no gap between adjacent elastic cushion members, it is difficult to insert a finger between the elastic cushion members, and it is difficult to remove any particular elastic cushion member when it is necessary to remove it. In the prior art 2, this is also difficult to take out.

In contrast, in prior art 3, since the elastic small members are formed with fine grooves in a checkered pattern around the elastic small members as a whole, the elastic small members can be displaced independently of each other, and thus, the sinking effect of the body can be exhibited better in prior art 3 than in prior art 1 or prior art 2. However, it is known that the elastic small components can be displaced independently of each other in this way, which causes a new problem.

The above-described problem related to the prior art 3 will be described with reference to fig. 5. Fig. 5 is an explanatory view for explaining the problem of the conventional art 3, and fig. 5 (a) is a schematic side view of the head side of the conventional cushion 200, in which five cubes, i.e., elastic members, are arranged in the width direction via fine grooves. Note that, although the entire conventional mat 200 is not shown, the elastic members are aligned in the width direction and the longitudinal direction as in the conventional art 3, and the elastic members are described as having a structure in which fine grooves having a checkerboard shape and being equally spaced are formed between adjacent members. Fig. 5 (B) is simulated as follows: the elastic members 30x in the center in the width direction are deformed by the load of the head 410 of the user while the user lies on the conventional mat 200, and the members 30y, 30y adjacent to the members 30x in the width direction are also deformed elastically by the deformation of the members 30 x. Fig. 5 (C) shows a state in which the user's head 410 turns in the direction of the arrow shown in fig. 5 (B). When such movement of the load occurs, the load is applied to the module 30x in the right direction of the paper surface, and therefore the right side surface 301 of the module 30x is deformed so as to press into the right adjacent module 30 y. Similarly, the right side surface 302 of the module 30y is deformed so as to be pushed into the right adjacent module 30z, and the right side surface 303 of the module 30z is deformed in the outward direction by the pressure.

Fig. 5 (D) simulates the following state: after the state of fig. 5 (C), the load on the head 410 of the user is removed. As shown in fig. 5 (D), the right side surface 303 of the right-side abutment-free block 30z returns to its original shape by self-restoring property. However, when a user turns over or the like, the elastic members 30x (side surfaces 301) and 30y (side surfaces 302) deformed so as to be forced into the adjacent members by applying a strong load in one direction may generate friction at the interface with the adjacent elastic members, and after removing the load, the elastic members may be maintained in a deformed state (hereinafter also referred to as a non-recovered state) without recovering to the original shape. In order to return to the flat state, the shape of the deformed elastic member must be restored by a manual operation, which is troublesome.

In addition, in the conventional art 3, since there is a gap between the elastic small components, the operation of taking out any specific elastic small component is easy. On the other hand, with prior art 3, there are the following problems related to insertion: when the elastic module is again installed in the space from which the specific elastic module has been taken out, it is difficult to align the engagement leg provided on the bottom surface of the elastic module with the engagement hole provided on the upper surface of the substrate, and it is difficult to insert the elastic module. In the case where the engagement leg is sufficiently hard, the above-described problem associated with insertion can be alleviated, but in this case, there is a risk that the engagement leg will come out of the engagement hole or a crack will occur at the root of the engagement leg when an operation such as turning over occurs on the cushioning member.

The present utility model has been made in view of the above problems. That is, the present utility model has an object of providing a mat in which a plurality of elastic members can be deformed independently of each other, and can be easily restored to an original shape naturally after such deformation is generated, and in which insertion and removal operations of specific elastic members can be easily performed at predetermined positions with respect to a lying part. The present utility model also relates to a method for providing a cushion, which involves providing the above-described excellent cushion, and has an object of providing a custom cushion to a user.

Means for solving the problems

The mat of the present utility model is characterized in that the mat comprises: a bottom layer cushion portion; a partition wall for partitioning the upper surface of the bottom mat portion into a plurality of partitions having a predetermined shape; and an elastic member inserted into the partition, wherein the height of the partition wall is 50% or less of the height of the elastic member, and the thickness of the partition wall is 1cm or more and 2cm or less.

In addition, a method of providing a mat according to the present utility model is characterized in that the mat includes: a bottom layer cushion portion; a partition wall for partitioning the upper surface of the bottom mat portion into a plurality of partitions having a predetermined shape; and an elastic member inserted into the partition, wherein the height of the partition is 50% or less of the height of the elastic member, and the thickness of the partition is 1cm or more and 2cm or less, wherein the mat collects personal information of a user, and wherein at least any one of the bottom mat portion, the partition, and the elastic member is selected from a plurality of specifications according to the personal information to constitute a personal mat, and wherein the personal mat is provided to the user.

Effects of the utility model

Since the elastic members constituting the mat of the present utility model are inserted and arranged in the partitions partitioned into the partition walls, the arrangement position can be easily maintained well, and the insertion work can be easily performed since the elastic members are provided to be inserted only into specific partitions.

In the present utility model, the partition wall is defined to have a significant thickness, and a sufficient gap is secured between adjacent elastic members. Therefore, the elastic member can be independently deformed when subjected to a load. In addition, the clearance is easily used to take out the determined elastic assembly.

Further, in the mat of the present utility model, since the height of the elastic members is at least twice the height of the partition wall, and the thickness of the partition wall is at least 1cm and at most 2cm, the elastic members are allowed to deform independently when they are subjected to load, and the occurrence of a non-return state after deformation is satisfactorily prevented.

First embodiment

A first embodiment of the present utility model will be described below with reference to fig. 1 to 3. Fig. 1 is a perspective view of a mat 100 according to a first embodiment of the present utility model, as seen from one end side in the longitudinal direction, in which a cover mat 50 provided on the upper surface side is folded to be approximately half in the width direction for easy visual recognition of an elastic unit 30. Fig. 2 is a sectional view taken along line II-II of the mat 100 shown in fig. 1, where (a) in fig. 2 shows a state in which the elastic members 30 are removed from the partitions 26, and (B) in fig. 2 shows a state in which the elastic members 30 are provided. Fig. 3 is an exploded perspective view of the mat 100.

First, the outline of the mat 100 will be described.

As shown in fig. 3, the mat 100 is configured as: the mat 100 has: a bottom mat portion 10; a partition wall 20 that partitions the upper surface of the underlying cushion portion 10 into a plurality of partitions 26 of a predetermined shape; and a resilient member 30 inserted into the partition 26. As shown in fig. 2 (B), in the mat 100, the height h1 of the partition wall 20 is 50% or less of the height h2 of the elastic members 30, and the thickness t1 of the partition wall 20 (see fig. 2 (a)) is set to be 1cm or more and 2cm or less.

In the mat 100 having this structure, the elastic members 30 inserted into the partitions 26 are well held by the partition walls 20, and the elastic members 30 are well prevented from being displaced and protruding from the partitions 26, so that the operation of inserting the elastic members 30 into the partitions 26 is easy. Further, since the thickness t1 of the partition wall 20 is 1cm or more and 2cm or less, the same degree of gap is formed between the adjacent elastic members 30, and the elastic members 30 are allowed to deform independently of each other when a load is applied, and the operation of removing a specific elastic member 30 is also facilitated.

The height h1 of the partition wall 20 in the present utility model is 50% or less of the height h2 of the elastic members 30, and thus, the cushion 100 is sufficiently allowed to deform independently of the elastic members 30 when subjected to a load, and the occurrence of a non-return state after deformation is satisfactorily prevented.

The details of the mat 100 will be further described below.

(bottom mat portion)

The underlying mat portion 10 is a flat plate-like structure provided on the lower side of the mat 100. In the present embodiment, the underlying cushion portion 10 is constituted by a sheet of a predetermined thickness. However, the structure of the underlying mat portion 10 is not limited to this, and may be any plate-like structure that can serve as a base of the mat 100, and may be, for example, a multilayer structure in which a plurality of sheets are stacked. Further, a bag-shaped fluid inclusion that can repeatedly supply and discharge fluid to and from the internal space can be used as the bottom layer cushion portion 10. As an example of the structure of the fluid bag body, an air cushion and the like are illustrated.

Structural members of the underlying cushion portion:

the members constituting the underlying cushion portion 10 are not particularly limited, but are preferably made of elastic members in view of light weight and capability of compressing the bundle. Here, the elastic member is a member capable of exhibiting self-restoring property that flexes under a load of a human body weight level and naturally returns to an initial shape when the load is removed. Specific examples of the elastic member include a foamed resin body, a fluid bag body capable of injecting exhaust gas into the interior, a spring bag body in which a spring is contained, and the like. Among them, the elastic member is preferably a foamed resin body in terms of a state in which the package is easily compressed and can be used without any effort after opening.

As the elastic member foaming resin body, polyurethane foam, polyethylene foam, polypropylene foam, polystyrene foam, and the like are exemplified, and among them, polyurethane foam is preferable from the viewpoints of light weight, elasticity, and self-recovery.

The thickness of the underlying mat portion 10 is not particularly limited, and is preferably adjusted in a range of 10mm to 100 mm.

(partition wall)

The mat 100 has partition walls 20, and the partition walls 20 partition the upper surface of the underlying mat portion 10 into a plurality of partitions 26 of a predetermined shape. Here, the partition 26 serves as a space for holding the elastic member 30. The elastic member 30 inserted and held in the partition 26 is supported by the partition wall 20 to a predetermined height of the side surface, and thus the stable feeling is good.

In the present embodiment, the partition wall bodies 22 arranged in the row direction and the partition wall bodies 22 arranged in the column direction are staggered in a lattice shape in a plan view, and the partition wall 20 is constituted by the partition wall outer edge portion 24 surrounding the outer edge in the circumferential direction. In the present embodiment, the partition 26 partitioned by the partition wall body 22 is square in plan view, and holds the elastic members 30 closely accommodated in the cubes of the partition 26.

Although not shown, the shape of the partition 26 in the present utility model is not limited to a square shape in a plan view, and includes various shapes. For example, the partition 26 may have a rectangular shape, a circular shape, an elliptical shape, a triangular shape, or any other arbitrary shape in plan view. In the present embodiment, the shape and size of the plurality of partitions 26 are uniform, but part or all of the plurality of partitions 26 may be different in shape and size.

In the present embodiment, the partition wall main body 22 is formed by arranging flat plate-like wall surfaces having a uniform thickness from the upper end to the lower end in a lattice shape, but the partition wall main body 22 may be formed to be thicker from the upper end toward the lower end as a modification not shown. In this case, the portion inserted into the partition 26 of the elastic member 30 may be configured such that the lower end portion thereof is tapered along the partition wall main body 22.

The method for manufacturing the partition wall 20 is not particularly limited, and for example, the partition wall 20 may be manufactured by forming the partition 26 by cutting out a predetermined position in the thickness direction using an elastic member having a single structure. In addition, a predetermined mold frame having convex portions corresponding to the partitions 26 may be prepared, and a foaming resin material such as a urethane foam material may be injected into the mold frame to form the partitions 26 as a plurality of concave portions, thereby manufacturing the partition walls 20. The partition 26 is a space partitioned by the partition wall body 22, and is a through hole in the present embodiment, but the partition 26 may be a bottomed non-through hole without departing from the gist of the present utility model.

As a modification not shown, for example, the partition wall 20 may be constituted by the partition wall main body 22 alone without the partition wall outer edge portion 24, and the frame body 40 may be designed to have a height larger than the thickness of the partition wall outer edge portion 24 alone, and the partition wall main body 22 may be provided in the frame of the frame body 40.

Thickness of the partition wall:

the thickness t1 of the partition wall 20 is set to be 1cm or more and 2cm or less. The thickness t1 of the partition wall 20 in the present utility model is the thickness of the upper end portion of the partition wall body 22 as seen in a plan view, and is equal to the distance between the elastic members 30 closely inserted into the partitions 26. In the present embodiment, the thickness of the partition wall is designed to be the same from the upper end portion to the lower end portion.

By setting the thickness t1 of the partition wall 20 to 1cm or more, the elastic members 30 inserted and provided in the partitions 26 are easily and firmly held, and the elastic members 30 can be sufficiently independently deformed. In addition, as described above, by securing the gap, the deformation of one elastic member 30 is less likely to affect the other elastic member 30, and when a load is applied to an arbitrary partition of the lying portion of the mat 100, the pressure of the load is less likely to be transmitted to the surrounding elastic members 30. Therefore, when two persons lie down in the mat 100, the vibration of the turn-over of one user is hard to be transmitted to the other user, and it is difficult to obstruct the sleep of the other user.

Further, by providing a gap of 1cm or more between adjacent elastic members 30, the air permeability of the mat 100 is good, and the inside of the mat 100 can be suppressed from becoming high humidity, and further, it is easy to insert a finger between the elastic members 30, so it is easy to grasp the elastic members 30 and take out the elastic members 30 held by the partition walls 20.

On the other hand, if the thickness t1 of the partition wall 20 exceeds 2cm, the user may feel uncomfortable when lying down on the mat 100, and if a load is applied, the elastic members 30 may deform excessively and sink independently, so that a good sleeping posture may not be achieved.

The thickness t1 of the partition wall 20 is determined in consideration of the relationship between the height of the elastic member 30 and the height of the partition wall 20. That is, it is important that the mat 100 is configured such that the height h1 of the partition wall 20 is 50% or less of the height h2 of the elastic members 30, and the thickness t1 of the partition wall 20 is defined to be 1cm or more and 2cm or less.

When the height h1 of the partition wall 20 exceeds 50% of the height h2 of the elastic member 30, the proportion of the elastic member 30 restricted by the partition wall 20 becomes excessive. As a result, in the case where the predetermined thickness t1 is secured, it is also difficult for the elastic member 30 to deform sufficiently independently, and it is difficult to achieve desired body pressure dispersion, and in addition, it may be difficult for the user to sufficiently feel the softness of the cushion 100. The height h1 of the partition wall 20 is preferably 40% or less, more preferably 35% or less of the height h2 of the elastic member 30 from the viewpoint of deforming the elastic member 30 more sufficiently independently.

In addition, when the elastic members 30 and the partition walls 20 are both formed of a foamed resin body such as polyurethane foam, the friction force between the members is high, so that it may be difficult to insert the elastic members 30 into the partition 26, and if the height h1 of the partition walls 20 is 35% or less of the height h2 of the elastic members 30, the insertion work is also easy, which is preferable.

When the height h1 of the partition wall 20 is too low with respect to the height h2 of the elastic member 30, the holding property of the elastic member 30 is insufficient, and there is a possibility that the arrangement state of the elastic member 30 becomes unstable. From the viewpoint of suppressing the occurrence of this problem, the height h1 of the partition wall 20 is preferably 15% or more, more preferably 20% or more, and even more preferably 25% or more, with respect to the height h2 of the elastic member 30.

As shown in fig. 2 (B), the height h1 of the partition wall 20 is a height from the upper surface of the underlying mat 10 to the upper end of the partition wall 20, and the height h2 of the elastic members 30 is a height from the upper surface of the underlying mat 10 to the upper end of the elastic members 30.

In the present embodiment, the plurality of elastic members 30 having the same height are used, but the present utility model is not limited thereto, and elastic members 30 having different heights may be used. In the manner in which the elastic members 30 having different heights are used as described above, the height h2 of the elastic member 30 is the most standard height of the elastic member 30, compared with the height h1 of the partition wall 20.

In the partition wall 20 including the partition wall outer edge portion 24, the width dimension of the partition wall outer edge portion 24 may be set to be larger than the width dimension of the frame body portion 40 described later in a range of 1cm to 2 cm. Accordingly, a gap of 1cm or more and 2cm or less is secured between the inner surface of the frame 40 and the elastic member 30 facing the inner surface of the frame 40, and therefore the elastic member 30 disposed adjacent to the frame 40 can be deformed independently on the side of the frame 40.

The members constituting the partition wall 20 are the same as the elastic members shown in the constituent members of the underlying cushion portion 10, and the above description is appropriately referred to, so that the detailed description thereof is omitted here. The member constituting the partition wall 20 is preferably a foamed resin body, and polyurethane foam is more preferred from the viewpoint of easy adjustment of the elasticity and hardness to a proper extent, easy production of the partition wall 26, and the like.

(elastic component)

The elastic members 30 are members constituting the lying portion of the mat 100, and are inserted into and held in the partitions 26 provided in the partition wall 20. Therefore, the size and shape of the partition 26 partitioned by the partition wall body 22 are designed to be the same as those of the portion of the partition 26 into which the elastic member 30 is inserted.

In the present utility model, the shape of the elastic members 30 is not particularly limited, and the elastic members 30 may be tightly inserted into the partitions 26, and a gap of the same extent as the thickness t1 of the partition wall 20 may be secured between adjacent elastic members 30. In the present embodiment, specifically, the elastic member 30 is a cube. If the elastic member 30 is a cube, any one of six faces may be disposed on the upper surface side, and if the one face is no longer in a good state due to wear or the like caused by use, any one of the remaining faces may be disposed on the upper surface side. In the case of a cube, the upper surface can be changed five times, so that the commodity life of the elastic unit 30 can be substantially prolonged and the economical efficiency can be achieved.

In order to sufficiently reflect the preference of the user, for example, the standard type of the elastic member 30 may be formed as a cube, and for this purpose, a type having a different height (either a higher height than the cube or a lower height than the cube, or both) may be formed by a rectangular parallelepiped.

The length of one side of the elastic member 30 as a cube is not particularly limited, but is preferably 10cm or more, more preferably 11cm or more, and even more preferably 12cm or more from the viewpoint of securing a sufficient deformation amount of the elastic member 30 when a load is applied and achieving good body pressure dispersion.

In addition, from the viewpoint that the weight is applied not through the surface but through the points (unit of modules) as in a general mat having a one-piece structure, and sinking according to the size of the weight is easily achieved, the length of one side of the cube is preferably 15cm or less, more preferably 14cm or less.

In the case of manufacturing the mattress 100 as a single-sized bedding, for example, if the elastic members 30 are cubes having one side of 10cm or more and 15cm or less, the width dimension of the frame portion 40 is about 7cm to 10cm and the gap between the adjacent elastic members 30 is ensured to be in the range of 1cm or more and 2cm or less, and 5 to 6 elastic members can be arranged in the width direction and 10 to 14 elastic members can be arranged in the length direction on the basis of this.

In addition, as described above, in the relation between the height h2 of the elastic member 30 and the height h1 of the partition wall 20, for example, when the height h2 of the elastic member 30 is 130mm, the height h1 of the partition wall 20 is 75mm or less, preferably 52mm or less, more preferably 45.5mm or less, and even more preferably 42mm or less. In this case, the height h1 of the partition wall 20 is preferably 19.5mm or more, more preferably 26mm or more, and still more preferably 32.5mm or more.

The members constituting the elastic unit 30 are the same as the elastic members shown in the constituent members of the underlying cushion portion 10, and the above description is appropriately referred to, so that the detailed description thereof is omitted here.

The elastic member constituting the elastic unit 30 is a member that can be used for the lying part of the mat, and can be appropriately selected from members that elastically deform under a load and exhibit self-recovery by removing the load. In view of the light weight, elasticity, self-recovery, ease of manufacture, cost, ease of disposal, and the like, the members constituting the elastic unit 30 are preferably made of the foamed resin body exemplified above, and among them, polyurethane foam is more preferred.

Since the elastic members 30 can be repeatedly inserted into and removed from the partitions 26, the members of the mat 100 can be handled as a set, and the members for replacement of the mat 100 can also be handled as individual products.

(frame portion)

The mat 100 of the present embodiment is provided with a frame portion 40, and the frame portion 40 is directly or indirectly raised upward from the outer edge portion of the underlying mat portion 10. The outer edge of the lying part formed by the plurality of elastic members 30 inserted and held in the partition 26 is surrounded in the circumferential direction when the frame body 40 is viewed in plan.

The height h3 of the frame body 40 exceeds the height h1 of the partition wall 20. This prevents the outermost elastic members 30 of the lying part from being separated in the outward direction of the mat 100, and also provides good stability due to the presence of the frame 40 when the mat 100 is moved or the like in a state where the mat 100 is spread. The height h3 of the frame 40 is a height from the upper surface of the underlying cushion 10 to the upper surface of the frame 40.

As shown in fig. 2 (B), in the present embodiment, the height h3 of the housing 40 is equal to the height h2 of the elastic member. This makes it possible to more sufficiently prevent the elastic members 30 located at the outermost side of the lying part from being separated along the outer side of the mat 100, and to form a significant height difference on the upper surface of the mat 100, so that it is preferable that the user is not uncomfortable.

The frame portion 40 in the present embodiment is continuous in the circumferential direction and has a zigzag shape. The method for manufacturing the frame 40 is not particularly limited, and the frame 40 may be integrally formed as a whole, or may be manufactured in a letter-like shape by joining a plurality of rod-like members. For example, two bar-shaped members for long sides and two bar-shaped members for short sides may be joined to form a square shape. The frame portion 40 is joined to and attached to the upper surface of the outer edge portion of the partition wall 20, and the outer side surfaces of both are designed to be the same surface.

Note that, the description of the elastic members shown in the constituent members of the underlying cushion portion 10 is appropriately referred to for the members constituting the frame portion 40, and therefore, the description thereof is omitted here.

(cover mat)

In the present embodiment, a cover mat 50 is provided for covering the lying part constituted by the plurality of elastic members 30. In the case where the user of the mat 100 has an uncomfortable feeling to the gap between the elastic members 30, the cover mat 50 can be used to cover so as to eliminate the uncomfortable feeling. In the case where the gap is used to with use, in order to properly remove the cover mat 50, as shown in fig. 1, the cover mat 50 is preferably handled as a separate body without being joined to the frame portion 40 or the like.

The thickness of the cover mat 50 can be appropriately designed by the members constituting the cover mat 50, and the like. For example, in the case where the cover mat 50 is made of a foamed resin such as polyurethane foam, the thickness of the cover mat 50 is preferably 1cm or more and 2.5cm or less, more preferably 1.5cm or more and 2.3mm or less, from the viewpoint of eliminating the uncomfortable feeling of the user to the elastic members 30 and sufficiently exhibiting the effect of dispersion of body pressure due to the plurality of elastic members 30 existing below the cover mat 50.

Note that, the members constituting the cover mat 50 are appropriately referred to above in the same manner as the elastic members shown in the members constituting the underlying mat portion 10, and thus detailed description thereof is omitted here.

(integral Structure of mat 100)

The underlying mat portion 50, the partition wall 20, and the frame body portion 40 are directly or indirectly laminated, joined, and fixed in this order, and can be integrally handled. In the present embodiment, the underlying cushion portion 50, the partition wall 20, and the frame body portion 40 are directly laminated to each other, but the present utility model does not prohibit lamination of any other layers on these boundary surfaces. In this regard, as described above, the cover mat 50 can be handled as a separate body, and the elastic unit 30 can be repeatedly inserted and removed.

The underlying cushion portion 50, the partition wall 20, and the elastic members 30 constituting the cushion 100 are each constituted by an elastic member. The members constituting these may be independent of each other, but the members are preferably unified into the same type because they are easy to discard. Among them, the underlying cushion portion 50, the partition wall 20, and the elastic members 30 are preferably composed of the same type of foamed resin body, and more preferably composed of polyurethane foam, from the viewpoint of easy manufacturing and easy adjustment of hardness and light weight. In addition, it is particularly preferable that the frame body 40 and the cover mat 50 are manufactured by using polyurethane foam together with the underlying mat 50, the partition wall 20, and the elastic members 30. As described above, the cushion 100 made of polyurethane foam has excellent shape recovery when the package is compressed and opened in a state of being rolled up in the longitudinal direction, and can be easily cut by scissors or the like when being discarded, and can be easily discarded as general garbage.

(hardness of each Structure)

The hardness of each structure of the mat 100 is not particularly limited, and can be adjusted in an appropriate range as a mat. In the present utility model, the hardness of each structure means 40% compression hardness (N) and can be measured in accordance with JIS K6400-2A method. In addition, more specifically, the hardness of the structure means the hardness of the members constituting the underlying cushion portion 10, the partition wall 20, the elastic members 30, the frame body portion 40, and the cover cushion 50.

Hereinafter, a description will be given of preferable hardness of each structure and a relative relationship between the hardness of each structure, with respect to a manner in which each structure constituting the cushion 100 is composed of a foamed resin body such as polyurethane foam.

Hardness of members constituting the underlying cushion portion:

the hardness of the members constituting the underlying mat portion 10 is preferably 150N or more and 270N or less, more preferably 170N or more and 250N or less, and still more preferably 190N or more and 230N or less, from the viewpoint of exhibiting moderate flexibility and stabilizing the entire support mat 100.

Hardness of members constituting the partition wall:

in order to sufficiently secure the holding property of the elastic member 30, it is desirable that the partition wall 20 has a moderately high hardness, and on the other hand, if the hardness is too high, the user may feel uncomfortable, so that moderate flexibility is required. Therefore, the hardness of the members constituting the partition wall 20 is preferably 200N to 350N, more preferably 250N to 330N, and even more preferably 270N to 310N.

Hardness of the members constituting the elastic assembly:

the hardness of the member constituting the elastic unit 30 may be determined by paying attention to the hardness of the member constituting the elastic unit 30 so as not to generate the feeling that the partition wall body 22 is touched by the body by being deformed excessively independently while showing good flexibility in view of the fact that the lying portion is constituted. Specifically, the hardness of the members constituting the elastic assembly 30 is preferably 50N or more and 200N or less, more preferably 60N or more and 180N or less, and still more preferably 70N or more and 170N or less.

The plurality of elastic members 30 inserted into the plurality of partitions 26 may have uniform or different hardness, and for example, the plurality of elastic members 30 may include three or more elastic members 30 having different hardness. In the present embodiment, specifically, three kinds of elastic members (elastic members 30a, 30b, 30 c) having different hardness are used.

As described above, by configuring the lying part using three or more elastic members 30 having different hardness, it is possible to design a hard partition and a soft partition locally intentionally, and it is easy to change the parts. Therefore, the user can appropriately change the arrangement position of the elastic members 30 having different hardness, and can set the cushion 100 to be suitable for his/her own preference. As will be described later, the cushion 100 can be provided in a customized state by arranging the elastic members 30 having different degrees of hardness in advance while collecting personal information (height, weight, sleeping posture, etc.) of the user.

Since the hardness can be selected for each of the elastic members 30 arranged in this manner, the hardness can be adjusted by dots (unit of members) in the lying portion as a surface, and the preference of the user can be sufficiently reflected. In addition, when the user lies down, the body pressure to the lying part differs depending on each part such as the head, back, waist, hip, leg, etc., and therefore the elastic members 30 having different hardness are arranged in consideration of these body pressures, whereby it is possible to satisfactorily disperse the pressure and realize a desired sleeping posture.

For example, when the plurality of elastic members 30 in the mat 100 include members having three types of hardness, the hardness of the elastic member 30c having the lowest hardness is preferably set to a range of 50N or more and less than 100N, the hardness of the elastic member 30b having the middle hardness is preferably set to a range of 100N or more and less than 130N, and the hardness of the elastic member 30a having the highest hardness is preferably set to a range of 130N or more and 180N or less.

In addition, in the case where the plurality of elastic members 30 in the mat 100 include elastic members 30 having different hardness, the color tone of the elastic members 30 may be changed for each hardness. By differentiating the colors in this way, the hardness is clearly visible, and the arrangement can be changed more easily.

Hardness of members constituting the frame portion:

the frame portion 40 can function as a support cushion 100 in the same manner as the underlying cushion portion 10. Therefore, from the viewpoint of exhibiting moderate flexibility and stably supporting the entire mat 100, the hardness of the members constituting the frame portion 40 is preferably 150N or more and 270N or less, more preferably 170N or more and 250N or less, and still more preferably 190N or more and 230N or less. In the present embodiment, the same member (for example, polyurethane foam) as the underlying cushion portion 10 is used for the frame portion 40, and the hardness of the frame portion 40 and the underlying cushion portion 10 are unified.

Hardness of the components constituting the cover mat:

the hardness of the members constituting the cover mat 50 may be determined in consideration of the point of view of exhibiting excellent flexibility and transmitting body pressure to the elastic members 30 disposed therebelow via the cover mat 50. Specifically, the hardness of the cover mat 50 is preferably 100N or more and 200N or less, more preferably 110N or more and 180N or less, and still more preferably 120N or more and 170N or less. For example, the hardness of the cover mat 50 is preferably the same as the hardness of the highest-hardness elastic member 30a among the elastic members 30 having different hardness.

Adjustment of hardness of each structure:

the preferable hardness range of each mat 100 is as described above, but the hardness of each structure can be adjusted relatively to each other.

For example, in the present embodiment in which the plurality of elastic members 30 inserted into the plurality of partitions 26 include three or more elastic members 30 (30 a, 30b, 30 c) having different hardness, the underlying cushion portion 10, the partition wall 20, the frame body portion 40, and the elastic members 30 are described by taking as an example a configuration in which each of them is formed using a foamed resin such as polyurethane foam.

In this embodiment, the hardness C1 of the foamed resin body constituting the partition wall 20 and the hardness C2 of the foamed resin body constituting the elastic member 30a having the highest hardness among the three or more elastic members 30 (30 a, 30b, 30C) having different hardness may be adjusted to the relationship of the following formula (1). Thereby, the elastic member 30 can be tightly held by the partition wall 20 having a height of 50% or less of the height h2 of the elastic member 30.

[ 1]

Partition wall hardness C1 > elastic component hardness C2 … … (1)

In addition, from the viewpoint of providing more excellent comfort in sleeping, the partition wall hardness C1 satisfies the following formula (2) in addition to the above formula (1), and the hardness C2 of the foamed resin body constituting the elastic member 30a having the highest hardness is preferably adjusted to satisfy the following formula (3).

[ 2]

Partition wall hardness C1-350N … … (2) of 200N-or less

[ 3]

130N is less than or equal to the hardness C2 of the elastic component is less than or equal to 180N … … (3)

The balance between the hardness C3 of the foamed resin body constituting the underlying mat portion 10 and the hardness C4 of the foamed resin body constituting the frame portion 40 is preferably, for example, the following.

[ 4]

The hardness C1 of the partition wall is greater than the hardness C3 of the bottom cushion part and is greater than or equal to the hardness C4 of the frame body part and is greater than the hardness C2 … … (4) of the elastic component

In the relation of the hardness of the above formulae (1) to (4), each member is preferably a foamed resin body, and more preferably a polyurethane foam.

Second embodiment

Next, a mat 120 according to a second embodiment of the present utility model will be described with reference to fig. 4. Fig. 4 is a partial plan view of the second embodiment of the present utility model, showing a state in which a user 400 lies.

The mat 120 of the second embodiment is constructed in the same manner as the mat 100 of the first embodiment except that the members constituting the elastic members 30 are all the same in hardness. Since all of the elastic members 30 have the same hardness and a proper gap is provided between adjacent elastic members 30, a comfortable mattress for sleeping can be provided that achieves excellent dispersion of body pressure.

In the present utility model, the elastic member 30 can be repeatedly inserted into and removed from the partition 26, and for example, as shown in fig. 2, the elastic member 30 at an arbitrary position can be removed and used as a lying part provided with a recess.

More specifically, as shown in FIG. 2, the elastic assembly 30 of the shoulder height of the user 400 can be removed to expose the partition 26 and place the shoulder and arm therein. In this sleeping posture, the arm rest can be easily performed for other users who are sleeping simultaneously, which is not shown. The use mode as described above can be implemented in the mat 100 according to the first embodiment.

Next, a method for providing a mat according to a third embodiment of the present utility model will be described. In this embodiment, a method of providing the mat 100 will be described with reference to fig. 1 to 3 as appropriate.

The mat 100 is provided by a mat providing method including: a bottom mat portion 10; a partition wall 20 that partitions the upper surface of the underlying cushion portion 10 into a plurality of partitions of a predetermined shape; and a resilient member 30 inserted into the partition 26. As described above, in the mat 100, the height of the partition wall 20 is 50% or less of the height of the elastic members 30, and the thickness of the partition wall 20 is 1cm or more and 2cm or less.

The provider of the mat 100 collects personal information of the user in advance, and based on the personal information, selects at least any one of the underlying mat portion 10, the partition wall 20, and the elastic members 30 from a plurality of specifications to constitute a personal mat and provide it to the user.

According to this providing method, the mat 100 can be provided in accordance with the preference, the body shape, and the like of the user. The importance of sleep is now widely understood, and the urgent desire to get more comfortable sleep is rising. According to the providing method of the present utility model, a mat matching personal information can be provided, and thus a user can easily obtain a customized mat suitable for himself.

Here, the personal information may be information reflecting personal preference, body shape, and the like in terms of sleep and rest. For example, personal information includes color, preference of the hardness of bedding, height, weight, main sleeping position, and the like.

For example, at least any one of the underlying cushion portion 10, the partition wall 20, and the elastic members 30 is set to a color that is preferred by the user based on personal information of the color, whereby the cushion 100 of a color tone that is customized by the user can be provided. In this case, for example, the plurality of elastic members 30 may be set to two or more different specifications, and the color of the lying part may be subjected to pattern processing by the plurality of colors.

Further, by confirming the preference of the hardness of the bedding in advance, at least any one of the underlying cushion portion 10, the partition wall 20, and the elastic members 30 is set to the hardness preferred by the user, and thus the individual preference is integrated to adjust the hardness of the entire cushion 100 to the content.

Further, the mat 100 having a lying part suitable for the hardness of the user can be provided by collecting personal information such as the height and weight of the user in advance. Hereinafter, an embodiment of the method for providing a mat according to the present utility model, including height and weight as personal information, will be described.

The method for providing the mat 100 according to the present embodiment is performed using the mat 100, and the plurality of elastic members 30 inserted into the plurality of zones 26 respectively include three or more elastic members 30 (30 a, 30b, 30 c) having different hardness with respect to the mat 100.

In the method of providing the mat 100, an information collection step of collecting personal information including the height and weight of the user who wishes to use the mat 100 is performed. The personal information further includes any information. Examples of the arbitrary information include a sleeping position of the user. Here, the sleeping posture means a sleeping posture (e.g., a supine posture, a lying posture, etc.) that the user likes.

Then, at least a mat base having the prepared underlying mat portion 10 and the partition wall 20 is prepared; in the information collecting step, based on the collected personal information, the pattern processing step of manufacturing the personal mat by disposing the three or more elastic members 30 (30 a, 30b, 30 c) having different hardness in the partition 26 is performed in a mode suitable for the user. The pattern suitable for the user means a pattern in which the dispersion of body pressure applied to the lying part based on the height, weight, and the like is analyzed and determined. The mode may be determined by the user of the mat 100, or a plurality of modes may be prepared in advance.

Further, as described above, the providing step of providing the completed personal mat to the user is performed. The providing step means a step of directly or indirectly transferring the personal mat to the user.
