Japanese Patent No. 4422604 JP 2002-191247 A JP 2004-16145 A JP, 2014-168400, A

As described above, in any of the conventional pet pads having the mat surrounded by the frame, the mat is made of the same material as the frame or a material softer than the frame. Therefore, for pets such as dogs with weak joints, there is a problem that it is difficult to walk on a soft mat and the joints are easily damaged. In addition, since the mat is partially dented according to the body pressure that is partially applied, partial force is applied to the lumbar bone and the like even in a sleeping state, and bed sores are likely to occur.

Therefore, it is an object of the present invention to provide a pet bed which is easy for a pet such as a dog to walk, does not damage joints, and has high walking stability.

The present inventor, as a result of extensive studies to solve the above problems, in a pet bed having a mat surrounded by a frame, by making the hardness of the mat harder than the frame, the pet's leg becomes a mat. The present invention has been completed based on the finding that it is possible to provide a pet bed having a high degree of walking stability, in which a pet can walk easily, joints are not easily damaged, and the depth of depression can be reduced.

Aspects of the present invention that solve the above problems include, but are not limited to:
(Aspect 1)
A pet bed comprising a frame having cushioning properties and a mat having cushioning properties surrounded by the frame,
The frame and the mat each have a height,
The height of the frame is higher than the height of the mat,
The mat has a fibrous structure made of thermoplastic resin fibers having an average fiber diameter of 0.01 to 5 mm,
A pet bed characterized in that, when the frame and the mat are compressed under the same pressure, the thickness of the mat compressed and reduced is smaller than the thickness of the frame compressed and reduced.

<Effect> A pet bed in which a cushioning mat that forms the bed floor is surrounded by a tall frame that has cushioning properties has a good feeling for pets, but in the case of a conventional pet bed, a mat is used. From the perspective of cushioning, the same material as or softer than that of the frame was used for the cushioning part, but the cushioning property (the soft elastic repulsion that receives the weight of the pet in a form that fits the pet's body) A mat that considers only strength) lacks hardness, which makes it difficult for pets to walk and has a problem in walking stability that the joints are easily damaged. In the bed of the present invention, unlike the conventional material, the mat is made of a material harder than the frame, so that the thickness of the mat that is compressed and reduced when the pet receives pressure during walking of the pet (sink depth). Since the frame body is smaller than the thickness (the depth of depression) that is compressed and reduced by the same pressure, the walking stability on the mat is enhanced, the pet can walk easily, and the joints are less likely to be damaged. In particular, in a structure in which the bed has a mat with a small thickness inside a tall frame, the mat is thin, and if the mat is soft, walking stability is further impaired. In addition, the walking stability can be improved, and the height of the frame can be reduced by the thickness of the mat, which makes it easier for the pet to straddle the frame. Is reduced.
By using a fiber structure composed of thermoplastic resin fibers having an average fiber diameter of 0.01 to 5 mm for the mat, the hardness of the mat can be increased, and further, the mat has cushioning properties and walking ability. It can have excellent hardness characteristics in both stability. Further, even when lying down, the entire surface of the mat sinks against the pressure that is partially applied, so that the body pressure is dispersed and bed sores are prevented.

(Aspect 2)
The pet bed according to aspect 1, wherein a thickness of the mat that is compressed and reduced when the frame and the mat are compressed at a pressure of 15 kPa is smaller than a thickness that the frame is compressed and reduced.
<Effect> If the pressure applied to the mat from the pet's leg when the pet walks is, for example, about 15 kPa (0.15 kgf/cm ² ) as the pressure applied to the mat by the four standard small dog legs. Since it was confirmed to be good, the hardness (hardness to sink) of the mat and the frame can be evaluated by comparing the compression reduction thicknesses of the mat and the frame when the pressure is applied. In the compression test based on the pressure of the four legs of the pet, the thickness of the mat that is compressed and reduced from the frame is small, so that the walking stability on the mat is enhanced for the pet, the pet easily walks, and the joints are damaged. It has a difficult effect.

(Aspect 3)
Aspect 1 or 2, wherein the mat has a plane direction and a thickness direction, and the fibrous structure is a fibrous structure which is bonded to an upper surface at an intersection of continuous fibers which does not include end portions of the continuous fibers. Pet bed.
<Effect> When the fiber structure having the cushioning property is joined to the upper surface at the intersection of the continuous fibers not including the end portions of the continuous fibers, the fibers are not biased in the mat, so that the foot It has the effect that it is hard to get caught and the compressibility does not change easily.It also reduces the discomfort caused by the contact of the end of the discontinuous fiber with the sole of the foot, and it does not easily disturb the walking balance. The feeling of discomfort caused by the parts coming into contact with the soles of the feet is reduced, and walking balance is less likely to be lost. Further, it has excellent dispersibility in body pressure, and the mat has a hardness characteristic that is excellent in both cushioning properties for a pet, particularly body pressure when a small dog lays down, and walking stability of the pet. it can.

(Aspect 4)
The pet bed according to any one of aspects 1 to 3, wherein the fibrous structure has a thickness of 3 mm or more when compressed at a pressure of 3.4 kPa.
<Effect> Since the cushioning properties of the mat are carried by the fiber structure, the thickness of the fiber structure when the fiber structure receives a pressure of about 3.4 kPa (35 gf/cm ² ) based on the body pressure when the pet, especially a small dog, lays down. Is 3 mm or more, the mat can have sufficient cushioning properties for a pet bed. Further, when the fibrous structure has a thickness of 3 mm or more when a load of about 3.4 kPa is applied, the mat further retains a cushioning reserve capacity against the load of the pet walking, thereby improving the walking stability of the pet. Can also be excellent.

(Aspect 5)
The pet bed according to any one of aspects 1 to 4, wherein a thickness of the mat that is compressed and reduced when the mat is compressed with a pressure of 15 kPa is 37 mm or less.
<Effect> Assuming that the pressure exerted on the mat from the pet's four legs when the pet walks is about 15 kPa (0.15 kgf/cm ² ) as the pressure exerted on the mat (fiber structure) by the small dog's four legs. When the thickness of the mat is 37 mm or less when the mat is compressed by receiving the pressure of 15 kPa (0.15 kgf/cm ² ) and the thickness is 37 mm or less, the depth that the pet's leg sinks when walking is small for the pet. Since it is small enough not to be a burden, it is possible to protect the pet's legs with excellent walking stability of the pet.

(Aspect 6)
Aspects 1 to 5, wherein the fibrous structure has a thickness that decreases when compressed at a pressure of 3.4 kPa within a range of 13 to 22 mm and a thickness that decreases when compressed at a pressure of 15 kPa is 35 mm or less. The pet bed according to any one of 1.
<Effect> When the thickness of the fibrous structure reduced when compressed at a pressure of 3.4 kPa is within the range of 13 to 22 mm, the fibrous structure has sufficient softness when subjected to the pressure when the pet lays down. If the fibrous structure has a thickness of 35 mm or less when compressed under the same pressure of 15 kPa as in the fifth aspect, the pet has a cushioning property that fits the body of the pet. Since the depth at which the legs sink is smaller than in the case of the fifth aspect, the walking stability of the pet is more excellent, and the legs of the pet can be protected.

(Aspect 7)
The fibrous structure has a surface layer on the upper surface side of the mat and an inner layer immediately below the surface layer, and the density of the surface layer is higher than the density of the inner layer. Bed for pets listed.
<Effect> Since the density of the surface layer of the fibrous structure in contact with the pet is higher than the internal density, the number of joints between fibers in the surface layer increases while maintaining the flexibility of the fibrous structure, and the pet joins the mat. Since the compressive load also entangles and disperses the fibers around the area in contact with the pet, the body pressure is highly dispersible, and it is possible to reduce the depression of the pet's whole body and legs when weight is applied. It

(Aspect 8)
The fibrous structure comprises a laminate of two fibrous structure layers including a layer containing no hollow fibers and a layer containing hollow fibers, and the fibrous structure layer containing no hollow fibers is provided on the upper surface side of the mat. The pet bed according to any one of aspects 1 to 7, which is arranged.
<Effect> The fiber structure is composed of a laminated body of two fiber structure layers including a layer containing no hollow fibers and a layer containing hollow fibers, and the fiber structure layer containing no hollow fibers is arranged on the upper surface side of the mat. If the upper surface side that contacts the pet has a soft cushioning property that fits the pet, the lower surface side that does not contact the pet increases the hardness (strength) by the hollow fiber structure layer. As a result, it is possible to reduce the sinking of the entire fibrous structure and to provide the pet with excellent compression stability for walking.

(Aspect 9)
The frame body uses a pressure plate which is chamfered (R10) at a corner of one plane of a disc having a diameter of 50 mm with a cross-sectional radius of 10 mm, and the chamfered side surface of the pressure plate is pressed against the frame body. 9. The pet bed according to any one of aspects 1 to 8, wherein a thickness of the frame body that is compressed and reduced when a load of 3.5 N is applied to the pressure plate is 10 mm or more.
<Effect> The hardness of the frame is 50 mm in diameter. One side of a flat plate is chamfered (R10) with a radius of 10 mm. When the frame body has a hardness (softness) of 10 mm or more when the frame body is compressed and reduced when a load of 3.5 N is applied to the pressure plate, the frame body is a pet, especially The hardness (softness) is suitable for pillows and backrests for small dogs.

(Aspect 10)
10. The pet bed according to any one of aspects 1 to 9, wherein the mat is removably fitted in the frame body and has a better moisture drying property than the frame body.
<Effect> The mat is removably fitted into the frame and has better moisture drying properties than the frame, so you can remove the mat that is easily soiled from the frame and wash only the mat, and the mat becomes dry. Being superior, it can reduce the time that the dog cannot use the bed due to washing and drying of the bed.

(Aspect 11)
The mat has a substantially rectangular shape in a plan view, the frame body surrounds the outer shape of the substantially rectangular shape of the mat, and has two substantially parallel long side portions and two substantially parallel short side portions, respectively. The pet bed according to any one of aspects 1 to 10, wherein one of the long sides has a frame height that is higher than the other three sides.
<Effect> Since pets such as dogs have the habit of sleeping along the wall, it is possible to use it as a back rest by adding a high part to the frame, and the two short shorts next to it that are lower than the back rest. The sides are used as pillows.

(Aspect 12)

(Pet bed)
As shown in FIGS. 1 to 3, a pet bed 1 according to an embodiment of the present invention has a rounded, substantially rectangular outer shape having a longitudinal direction L and a width direction W in a plan view. ing. In the present invention, the outer shape of the pet bed in plan view is not limited to the shape of such an embodiment, and an arbitrary shape (for example, according to the size or desired designability of the target pet (for example, A circle, an ellipse, a square, a triangle, a star, etc.) can be adopted. The size of the pet bed 1 can be appropriately set according to the size and type of the pet using the bed. For example, when the pet is a small dog or a medium-sized dog, the length in the longitudinal direction L is , 400 mm to 1400 mm, and the length in the width direction W is 250 mm to 1200 mm.

As shown in FIGS. 1 to 3, the pet bed 1 includes a frame-shaped frame body 2 along each side of a substantially rectangular shape having a longitudinal direction L, a width direction W, and a thickness direction T, and the frame body 2. And a mat 3 having a cushioning property and having a substantially rectangular parallelepiped shape.

As shown in FIGS. 1 to 3, the pet bed 1 has a main body portion 2S of the frame body 2 that is raised upward (height is high), and is surrounded by the main body portion 2S. The portion is configured as a recess 2R recessed to the back surface side. A mat 3 having a cushioning property is arranged on the back side of the bottom surface of the recess 2R so that the pet body can be supported on the bottom surface of the recess 2R while dispersing the body pressure of the pet. ing. Therefore, the pet can lie down on the recess 2R as a bed and rest in the recess 2R.

(Frame)
The main body portion 2S of the frame body 2 forms a peripheral portion of the bed 1 and surrounds the substantially rectangular recess 2R, and has a frame-like plan view shape along each side of the substantially rectangular shape. , Are joined by four corners where each side meets. The connecting portion of the four corners is a portion that connects the four sides and does not directly carry out the function of each side described below, but connects adjacent sides continuously (progressively). The connecting portion is formed so as to have the function of the adjacent side while taking over the function of the two connected sides.

As shown in FIG. 1, a frame in which one of the four sides forming the main body portion 2S forming the peripheral edge of the frame body 2 is relatively raised above the other side (that is, the height is high). It is formed as the body height portion 2B and can function as a backrest or the like of the pet lying in the recess 2R. On the other hand, three of the four sides forming the main body portion 2S are formed as a first frame lower portion 2P and a second frame lower portion 2E having a relatively lower height than the frame high portion 2B. The pet can easily move in and out of the recess 2R, and the pet lying in the recess 2R can function as a pillow on which the head can be placed. In particular, when the pet sleeps with its back on the frame body high portion 2B, which is one of the long sides of the rectangle, the first frame body lower portion 2P, which is the two rectangle short sides on both sides of the frame body high portion 2B, has the frame body height. It is lower in height than the portion 2B and is suitable for functioning as a pet pillow. In addition, of the four sides forming the main body portion 2S, one long side that is the frame body high portion 2B and the remaining one long side that is the first frame body lower portion 2P are the other long sides as a pet pillow. Can also function, but especially as a doorway for pets. Therefore, the heights of the two rectangular short sides are formed to be lower than the height of the frame body as the first frame body lower portion 2P, and the heights of the other rectangular long sides parallel to the frame body height portion 2B are set to the first frame body. It is preferable to form the second frame lower portion 2E lower than the height of the lower portion 2P to enhance the function as a doorway for pets.

The height of each part (each side) of the frame body 2 is usually the highest at the center position in the length direction and the width direction in plan view of each part, and is therefore represented by the height at the center position. It is possible to measure, but as the average height, measure the maximum height on the boundary line (3 places) that divides the part (here excluding the connecting part) into four equal parts in the length direction. However, the average value can also be used. The height of each part (each side) of the frame 2 is measured by placing a pressure plate at the measurement position of each part and measuring the height when a pressure of 51 Pa is applied in the vertical direction. Normally, the size of the pressure plate does not matter, but when the type of pressure plate is a problem depending on the measurement location, the pressure plate is chamfered (R10) with a radius of 10 mm at one flat surface of a disc having a diameter of 50 mm. Is used to measure the thickness when a load of 0.5 N is applied to this pressure plate, and the value is used as the thickness of the frame. In the bed 1 of this aspect, the bottom of the frame 2 is installed so as to be in direct contact with the place where the bed is installed, so the height of the frame 2 is substantially equal to the thickness of the frame, and the recess of the frame 2 is The depth of 2R is the depth obtained by subtracting the thickness of the mat 3 from the thickness (height) of the frame body.

However, leg portions may be provided at the bottom of the frame body 2 in consideration of air permeability and hygiene, and in that case, the height of the frame body 2 is the total height of the leg portions and the main body portion 2S of the frame body. Therefore, the thickness of the main body portion 2S of the frame body 2 does not match the height of the frame body 2. Also, the mat can be installed at a height such that the bottom of the mat does not match the bottom of the frame.

Since the frame body 2 functions as a backrest or a pillow of the pet as described above, it is desirable that the frame body 2 has a predetermined cushioning property. In the present invention, the frame body 2 is formed softer than the mat 3 but the second frame of the frame body 2 is used. Since the lower body portion 2E mainly functions as an entrance/exit, in order to make it easier for the pet to walk when stepping on the frame body to move in and out of the bed, the body lower portion 2E and the lower frame body lower portion 2E are relatively moved. It is preferable to form it hard. Here, in order to measure the hardness of each part of the frame body, for example, in order to apply the same pressure, using a chamfered disk having the same diameter of 50 mm as that used for measuring the thickness of the frame body described above. , For example, measure the thickness that is compressed and reduced when compressed with a load of 3.5 N, or make the thickness that is compressed and reduced the same (for example, 10 mm) and measure the load applied to the pressure plate at that time. By measuring, it is possible to measure and compare. If the thickness that is compressed and reduced when a load of 3.5 N is applied using the above pressure plate is 10 mm or more, consider that the frame has sufficient cushioning properties as a pet pillow or backrest. You can On the contrary, the load at which the frame body is compressed and reduced in thickness to 10 mm when a load is applied using the above pressure plate is 3.5 N or less, further 3 N or less, 2 N or less, 1 N or less. In this case, the frame body has a cushioning property used as a pillow or backrest for pets.

When the hardness of the frame is measured using a pressure plate that is chamfered (R10) with a cross-sectional radius of 10 mm at one corner of one plane of a disk having a diameter of 50 mm, it is usually the position at the center of the longitudinal direction of each part and It may be measured at the center position in the width direction. However, if necessary, the hardness at the center on the boundary line (three places) that divides each part into four equal parts can be measured and corrected by the average value.

As shown in FIG. 3, the main body portion 2S of the frame body 2 is configured by covering the frame body cushion material 21 with the frame body cover 22.

The material forming the frame cushion material 21 is not particularly limited, and for example, a cushion material known in the art such as cotton (cotton) fiber, urethane foam, or foam beads can be adopted. The material forming the frame cover 22 is not particularly limited, and may be, for example, a cloth made of natural or synthetic fibers or a synthetic resin sheet. A sheet using a synthetic fiber such as polyester is preferably used in terms of excellent stain resistance and wiping-off property. A knitted or mesh-like sheet is preferably used as the sheet having excellent air permeability. The material forming the frame cover 22 may be the same material as the mat cover. In order to manufacture the frame body 2, for example, the frame body cushion material 21 formed in a predetermined shape may be covered with a frame body cover 22 and sewn, or the frame body cover formed in a predetermined shape may be manufactured. A frame body having a predetermined shape may be produced by putting the frame cushion material 21 in 22 and sewing.

Further, the main body portion 2S of the frame body is formed by combining a plurality of structures (for example, four substantially linear structures) even if the main body 2S of the frame is formed by an integral body having the above-mentioned frame-shaped structure. May be.

Further, in the concave portion 2R of the frame body surrounded by the main body portion 2S of the frame body, as shown in FIG. 2, the bottom portion 23 is a mesh-like cloth continuous from the back surface of the frame body 2 (for example, by a synthetic fiber). It is formed of a woven fabric or a knitted fabric, etc., and has air permeability so that moisture or the like does not collect in the mat 3 fitted in the recess 2R. The above mesh-shaped cloth may have a sufficient strength to support the mat 3, and thus the mesh may have a coarse roughness, but it is attached over the entire back surface of the frame portion. ..

Note that the pet bed of the present invention is not limited to such a structure, and for example, in the main body portion (peripheral portion) of the frame of the bed, two of the four sides (excluding the connecting portion) are provided. It may be formed as a high frame body having a high height (the average value of the heights at three places on the quadrant of the length as described above), or all four sides have the same height. May be. When the main body portion (peripheral portion) of the bed frame has a circular shape in plan view, a part of the circular peripheral portion may be formed as a high bed height portion.

(mat)
As shown in FIGS. 1 to 3, the mat 3 of the pet bed of the present embodiment is present in the recess 2R formed by the frame 2 of the bed 1 and is detachably fitted into the frame 2. There is.

As shown in FIG. 3, the mat 3 is a sheet having a substantially rectangular shape in a plan view. As shown in the cross-sectional view of FIG. 3, the mat 3 includes a fiber structure 31 inside and a mat cover 32 that covers the fiber structure 31. Become. The fibrous structure 31 is also a sheet having a substantially rectangular shape in a plan view, and can be inserted into and removed from the mat cover 32, for example, through an opening 33 provided on a side surface of the mat cover 32. The opening 33 is a zipper or a button. It can be formed so as to be openable and closable.

The pet bed mat 3 according to this aspect is characterized in that the thickness (the depth of depression) that is compressed and reduced from the frame body 2 when the same pressure is applied is small. The hardness of the mat can be evaluated by applying pressure using a flat plate as a pressure plate and measuring the pressure and the compression reduction thickness (sink depth). Since the mat 3 and the fibrous structure 31 are generally substantially sheet-shaped, the mat 3 and the fibers can be measured by using a flat plate (for example, 100 mm in diameter) having a certain area or more to measure the hardness characteristics. The hardness (compression characteristic) of the structure 31 can be accurately measured. Therefore, the hardness (difficulty of sinking) between the mat and the frame can be easily compared by measuring the frame with the same pressure plate.

However, since the shape of the frame body 2 is not always flat on the upper surface and the width may not be large, for the purpose of comparing the hardness of the mat and the frame body, for example, one flat surface of a disc having a diameter of 50 mm is used. A chamfered (R10) pressure plate with a corner radius of 10 mm is used to press the chamfered surface of the pressure plate against the frame and mat, and the frame and mat are attached with the same load (pressure). It is possible to compare the thicknesses (sink depths) of the frame and the mat that are compressed and reduced when compressed. In this specification, when pressure is applied using the pressure plate, the bottom surface of the pressure plate is considered to be a circular plane having a diameter of 50 mm, the area (19.6 cm ² ) is calculated, and the applied load is The value obtained by dividing by the area is described as pressure. When the compression characteristics are measured using the chamfered pressure plate, the same pressure value as in the case of applying pressure using a circular flat plate having a diameter of 100 mm is used in the method for measuring the compression characteristics of the mat and the fiber structure described later. It should be noted that even when compressed, the actual pressure applied to the object to be measured is not the same, and as a result, the thickness reduced due to compression is not necessarily the same.

Using the chamfered pressure plate described above, the thickness of the mat compressed and reduced when compressed at a pressure of about 15 kPa is the thickness of the frame body compressed and reduced when compressed at the same pressure plate and the same pressure. If it is smaller, the mat is harder than the frame body (the compression reduction thickness is small) at the pressure corresponding to the pressure of the four legs of the pet, so that the walking stability of the pet bed can be excellent. The pressure of about 15 kPa is assumed to be the pressure of the standard four small dogs of a small dog applied to the mat. Therefore, compared with these pressures, the mat has a reduced compression thickness (depression) than the frame body. When the depth is small, walking stability is excellent for the pet.

In this hardness (compression) test under a pressure of about 15 kPa, the difference in thickness between the mat and the frame body when compressed and reduced is preferably 3 mm or more, and more preferably 5 mm or more, 8 mm or more, 10 mm or more. .. Further, depending on the types of the frame body and mat used, it may be further 12 mm or more, 15 mm or more, 18 mm or more, 20 mm or more, 25 mm or more, 30 mm or more.

When the pressure plate having the above chamfer is used and compressed at a pressure of about 15 kPa, the thickness of the mat is preferably 3 mm or more. When the pet walks on the mat, even if pressure is applied from the four legs, the minimum thickness remains in the mat, so that the mat can receive the pet's leg, and the depression of the pet's leg can be reduced, Useful in protecting the pet's legs. At the time of the above compression, the thickness of the mat is preferably 5 mm or more and 8 mm or more. Further, the remaining thickness can be 10 mm or more, 12 mm or more, and 15 mm or more, but it is not necessary to remain thicker than necessary.

The mat 3 of the pet bed according to the present embodiment uses a pressure plate which is chamfered (R10) with a cross-sectional radius of 10 mm at one flat surface of a disc having a diameter of 50 mm. The thickness by which the mat is compressed and reduced when the mat is compressed with a pressure of 15 kPa by pressing the surface may be larger than 37 mm, but is preferably 37 mm or less. When the compression reduction thickness is 37 mm or less, in a small dog having a standard weight corresponding to this pressure, the depth of depression of the pet's leg during walking is advantageously small to protect the pet's leg. This is because the walking stability of a small dog is excellent and it is preferable for protecting the legs of a pet. If the mat has a hardness satisfying the above conditions, even if the weight of the pet is smaller, the depression of the mat is smaller by the amount of the weight of the pet being smaller. It can be excellent in stability. The thickness of the mat that is compressed and reduced is more preferably 35 mm or less, and further preferably 32 mm or less, 30 mm or less, 27 mm or less, 25 mm or less, 24 mm or less from the viewpoint of pet protection. .. It should also be noted that the preferred value for the reduced compression thickness of this mat is related to the type of pet and the thickness and hardness characteristics of the mat.

As shown in the perspective view of FIG. 4(a) and the side view of FIG. 4(b), the fiber structure 31 of the present embodiment is composed of thermoplastic resin fibers, and has an average fiber diameter of 0.01 to It is 5 mm. By using a fiber structure composed of thermoplastic resin fibers having an average fiber diameter of 0.01 to 5 mm for the mat, the hardness of the mat can be increased, and further, the mat has cushioning properties and walking ability. It is also easy to have excellent hardness characteristics in both stability. The average fiber diameter is preferably 0.05 to 3 mm, more preferably 0.1 to 2 mm, 0.3 to 0.8 mm, and 0.4 to 0.6 mm. The strength and hardness of the fiber structure can be increased by configuring the fiber structure with thermoplastic resin fibers having a large average fiber diameter. Further, even if the same amount of thermoplastic resin fiber is used as the hollow fiber, the strength and hardness of the fiber structure can be increased. One preferable fiber structure is a network structure in which the intersections of polyester continuous fibers having an average fiber diameter of 0.4 to 0.6 mm are fused, and the density is 0.03 to 0.04 g/cm ³ (voids). The ratio is 95% or more) and the sheet has a thickness of 35 to 45 mm.

Here, the fiber diameter of the fibers forming the fiber structure can be measured as follows. First, a fiber having a predetermined length (for example, 5 mm) is cut out from any 10 points of the fiber structure to be measured, and the end portion of the cut out fiber is cut at a right angle to the extending direction of the fiber. The cut surface is photographed at a predetermined magnification, and the fiber diameter (mm) of the fiber is measured from the obtained cross-sectional photograph. For the fiber diameter, the average value of the fiber diameters of the 10 cut fibers is adopted.

It is preferable that the fibrous structure is a net-like structure in which fibrous materials of the thermoplastic resin are randomly entangled and joined to each other. As the thermoplastic resin fiber forming the fiber structure, for example, polyester resin, polyamide resin, polyether resin, polyolefin resin, or the like can be used. Non-hydrophilic thermoplastic resin fibers are preferred from the viewpoints of stain resistance, washability, dryability, and the like.

The fibrous structure 31 is preferably a fibrous structure that is joined at the intersections of continuous fibers, especially a fibrous structure that is joined at the intersections of continuous fibers that do not include the ends of the continuous fibers on the upper surface. If the mat is a fibrous structure joined at the intersections of the continuous fibers, especially a net-like fibrous structure joined at the intersections of the continuous fibers not including the ends of the continuous fibers on the upper surface, Since it is not biased, it has the effect that the foot is hard to be caught and the compressibility is not easily changed, and the discomfort caused by the end of the discontinuous fiber contacting the sole of the foot is reduced, and it is difficult to lose the balance of walking. Also, the discomfort caused by the contact of the ends of the discontinuous fibers with the soles is reduced, and the balance of walking is less likely to be lost. Moreover, since the continuous fibers extend in the horizontal direction, the dispersibility in body pressure is excellent. In particular, when continuous fibers having a large fiber diameter and strength are twisted, entangled with each other, and are joined at the intersections, a net-like continuous fiber structure with high porosity is formed, and they are joined at the intersections. The reticulated continuous fibers act like an aggregate of springs and exhibit high resilience characteristics (compression bounce characteristics). When the continuous fibers constituting the fiber structure are joined at many intersections in the length direction and the degree of freedom in the length direction is small, a force in the thickness direction is received by elastic deformation in the thickness direction of the continuous fiber itself, The compression force of the entire fibrous structure can be increased. In addition, when the continuous fibers extend in the horizontal direction perpendicular to the thickness direction and are joined at the intersections, the pressure applied in the thickness direction of the fibrous structure is also received in the horizontal direction by the continuous fibers extending in the horizontal direction. , Horizontal pressure distribution occurs, resulting in a larger area of the mat receiving pressure from the pet's legs and less subsidence.

The fibrous structure 31 preferably has a thickness of 3 mm or more when subjected to a pressure of 3.4 kPa (35 gf/cm ³ ). In this aspect, the cushioning property of the mat is taken by the fibrous structure. If the thickness of the mat is 3 mm or more when it receives a pressure of about 3.4 kPa (35 gf/cm ² ) based on the body pressure of a pet, especially a small dog (body pressure when lying down), the mat is a sufficient cushion for a pet bed. Can have sex. Further, when the fibrous structure has a thickness of 3 mm or more when a load of about 3.4 kPa is applied, the mat further has an elastic (repulsive) surplus force against the pressure of the legs of a pet, especially a small dog when walking. By possessing it, the walking stability of the pet can be excellent. The fibrous structure 31 may have a thickness of 8 mm or more, 10 mm or more, and 15 mm or more when subjected to a pressure of 3.4 kPa. Furthermore, this thickness may be 20 mm or more. The upper limit of this thickness is not the thickness of the fibrous structure when it is subjected to a pressure of 3.4 kPa, but the thickness of the fibrous structure reduced by this compression is the thickness showing sufficient cushioning properties for a pet bed. It depends on whether or not. The thickness of the fibrous structure, which is reduced by compression when it receives a pressure of 3.4 kPa, is preferably 15 mm or more, more preferably 20 mm or more, in consideration of the body pressure when a pet, particularly a small dog is lying down. ..

In order to measure the thickness of the fibrous structure when it is subjected to a predetermined pressure, a pressure plate having a certain area or more (for example, a circle with a diameter of 100 mm) is pressed against the fibrous structure at a predetermined pressure, and the fibrous structure is pressed. The body thickness may be measured. However, in this thickness measurement, the thickness when the initial pressure of 51 Pa is applied is taken as the zero point.

Further, the fibrous structure preferably has a thickness that decreases when compressed at a pressure of 3.4 kPa within a range of 13 to 22 mm, and a thickness that decreases when compressed at a pressure of 15 kPa is 35 mm or less. When the fibrous structure has a thickness of 13 to 22 mm, which is reduced when compressed by a pressure of about 3.4 kPa based on the body pressure of a pet, particularly a small dog lying down, the fibrous structure becomes a pet. Has a soft cushioning property (sink depth) that fits. Further, when the fibrous structure has a thickness of 35 mm or less that is reduced when compressed by a pressure of about 15 kPa that is expected to be received from the legs of a pet, particularly a standard small dog, when the pet walks, Since the depression of the entire mat is small even at times, the walking stability of pets including the pet (including pets having a lighter weight than the pet) can be remarkably excellent. The fibrous structure having such compression (elasticity) characteristics includes the fiber material, fiber diameter, fiber length, selection and combination of solid fiber and hollow fiber, entanglement of fibers, porosity, density, laminated structure, etc. It can be created, obtained, and is practical by adjusting. The thickness that decreases when compressed at a pressure of about 15 kPa is more preferably 32 mm or less, and further preferably 30 mm or less, 27 mm or less, 25 mm or less, 24 mm or less from the viewpoint of pet protection. In one preferred embodiment, the fibrous structure has a thickness decreasing range of 15 to 18 mm when compressed at a pressure of 3.4 kPa, and a thickness decreasing range of 22 to 27 mm when compressed at a pressure of 10 kPa. And the thickness that decreases when compressed at a pressure of 15 kPa is 30 to 35 mm.

The fibrous structure is preferably in the form of a sheet having a thickness of 20 to 80 mm. Since the fibrous structure having a cushioning property is in the form of a sheet having a thickness of 20 to 80 mm, the mat has a cushioning property that fits the pet body, especially a small dog as described above, and the matting property of the pet, and the pet's body. It is possible to easily realize that the hardness characteristics are excellent in both walking stability. The thickness of the fiber structure is preferably about 25 to 60 mm, more preferably about 30 to 50 mm and about 45 to 55 mm. The thickness of the fibrous structure is obtained by applying a flat plate having a diameter of 100 mm on the fibrous structure and applying a pressure of 51 N, and measuring the thickness at any three or more positions of the fibrous structure. Calculate the averaged value and use it as the thickness.

The fibrous structure is a fibrous structure in which continuous fibers of thermoplastic resin fibers having an average fiber diameter of 0.01 to 5 mm are bonded (especially fused) at the intersections thereof, whereby the above compression (elasticity) is achieved. It can function as a cushion with characteristics. A fiber structure composed of such continuous fibers has a reticulated structure, has the above-mentioned average fiber diameter and thickness, and has a porosity of 90% or more, so that the above preferable compression (elasticity) characteristics can be obtained. It is preferable for obtaining. This density of such fiber structure may be a ^{0.01~0.2g / cm 3, 0.01~0.1g / cm} 3, more 0.02~0.05g / ^cm 3, It is more preferably 0.03 to 0.04 g/cm ³ .

The porosity of the fibrous structure is occupied by the fibers of the fibrous structure by cutting out a sample with a thickness of 15 cm×15 cm from the fibrous structure to be measured and immersing the sample in an appropriate liquid. It is possible to measure the volume (fiber volume), divide the fiber volume by the apparent volume of the fiber structure, multiply by 100 to obtain the volume% of the fiber, and obtain the difference between the volume% and 100%. it can. When the liquid does not enter the hollow of the hollow fiber when immersed in the liquid, the density measured by the above method is considered to be the density of the hollow fiber. The apparent volume of the fiber structure is obtained by calculating from the external dimensions of the fiber structure (15 cm×15 cm×thickness in the above sample), and the method for measuring the thickness of the fiber structure has been described above. In addition, the porosity of the fiber structure can be roughly calculated from the density of the fiber structure and the density of the fibers. For example, if the density of 0.035 g / cm ^3, when the density of the fibers (polyester) and 1.35 g / cm ^3, the porosity is (1.35-0.035) in /1.35=97.4Pasento is there.

The density (apparent density) of the fiber structure can be determined as follows. First, a sample having a size of 15 cm×15 cm is cut out from the fibrous structure to be measured while keeping the thickness, and the mass (g) of the sample is measured. Next, the thickness (cm) of the sample cut out is measured, and the volume (cm ³ ) of the sample is calculated. Finally, the value of the density (apparent density) (g/cm ³ ) can be obtained by dividing the mass of the sample by the volume. The measurement of the thickness for measuring the density (apparent density) of the fiber structure is different from the measurement of the thickness of the bed frame and the mat, and is measured with a ruler without applying pressure. When the fibrous structure does not have a certain thickness, the measurement object is placed on a horizontal plane, and the height at any four positions (the distance from the horizontal plane to the top surface of the measurement object) is measured, The average value is adopted.

Although not limited, the fibrous structure has a surface layer 31S on the upper surface side and an inner layer 31C immediately below the surface layer as shown in FIG. 4B, and the density of the surface layer 31S is the inner layer 31C. Those having a density higher than that of are preferably used. The surface layer 31S is a layer containing fibers forming the surface of the fiber structure, and the thickness thereof may be, for example, 1 to 3 mm. The presence of the surface layer 31S and the inner layer 31C and the difference in their densities may be confirmed by visually observing that the fiber structures have a layer-like difference in fiber density from the upper surface toward the inner surface in the thickness direction. When the surface layer 31S of such a fibrous structure is used on the upper surface side of the mat, the density of the surface layer of the fibrous structure in contact with the pet is higher than the internal density, so that the flexibility of the fibrous structure is maintained and the surface is maintained. The number of joints between fibers in the layer increases, and the compressive load applied to the mat from the pet is also dispersed by entraining the fibers around the area in contact with the pet, so the body pressure dispersibility is high and the pet when weight is applied It is possible to reduce the subduction of the whole body and legs of the subject.

Further, the fibrous structure can be composed of a laminate of a plurality of fibrous structure layers having different hardness. When the fibrous structure is composed of a laminate of a plurality of fibrous structure layers having different hardnesses, a layer having a soft cushioning property that fits a pet and a layer having a hard cushioning property (repulsive force) and improving walking stability Since it can be combined with, there is an effect that a fibrous structure having both characteristics of soft cushioning property (fitting property) and hard cushioning property (walking stability) can be easily produced as a whole fibrous structure.

In particular, when the fibrous structure is a laminated body composed of a relatively soft layer 31U and a hard layer 31L as shown in FIG. 4C, the soft layer 31U receives the body pressure of the pet and the pet body. The hard layer 31L can be configured so as to have excellent cushioning properties for fitting with the above and to have excellent walking stability by reducing sinking of the mat. The relatively soft layer 31U and the hard layer 31L may be on either side, but in order to fit the pet's body, the soft layer 31U is preferably disposed on the upper surface side of the mat 3 in contact with the pet.

As the laminated body composed of the relatively soft layer 31U and the hard layer 31L, a laminated body of two fiber structure layers having different fiber diameters and fiber densities of the fiber structure is used. A two-layer laminate of a fiber structure layer not containing it and a fiber structure layer containing hollow fibers can be used. When such a fibrous structure, particularly the latter, is used and a fibrous structure layer containing no hollow fibers is disposed on the upper surface side of the mat, the upper surface side in contact with the pet has a soft cushioning property that fits the pet. On the lower surface side that does not contact the pet, the hardness (strength) can be increased by the hollow fiber structure in the fibrous structure layer, so that the subduction of the entire fibrous structure is reduced and the walking stability of the pet is improved. It is preferable because it can have excellent compression characteristics.

(Example of fiber structure)
As one example of the fiber structure, a continuous solid fiber of polyester is entangled, and the intersection is a fiber structure in which the intersections are fused to each other, and the sheet has a size of 200 mm×200 mm and a thickness of 40 mm, and an average fiber diameter of 0.5 mm. The results of measuring the compression characteristics of the fiber structure (Sample 1) having a density of 35 kg/m ³ are shown below together with the measuring method.

Similarly, another example of the fiber structure is a fiber structure in which continuous fibers of polyester are entangled with each other and the intersections thereof are fused to each other, and the sheet has a size of 200 mm×200 mm and a thickness of 40 mm. It is a laminated body of 20 mm thick layers, one layer is composed of solid fibers with an average fiber diameter of 0.5 mm, the other layer is composed of hollow fibers with an average fiber diameter of 0.65 mm, and each layer has a density of 35 kg. Table 1 below shows the results of measuring the compression characteristics of the fiber structure having a density of /m ³ . However, the densities of the solid fibers and hollow fibers in this case are the densities calculated from the mass of the charged material, and the synthetic fibers of the same mass are used to produce solid fibers and hollow fibers with different average fiber diameters. Was used.

(Measuring method)
Using a pressure plate having a diameter of 100 mm, the thickness of the sample when an initial pressure of 51 Pa is applied is set to zero, and the pressure plate is compressed to 75% of the sample thickness at a pressure plate speed of 100 mm/min using the same pressure plate, and the same. The pressure plate was returned to the zero point at the pressure plate speed and pre-compressed. Then, the compression was started at the same pressure plate speed, and the pressure when compressed to 25% of the thickness of the sample was similarly compressed to 40%, 50%, 60%, 65%, 70%, 75% of the thickness. 25% compression hardness, 40% compression hardness, 50% compression hardness, 60% compression hardness, 65% compression hardness, 70% compression hardness, 75% compression hardness, 77 The compression hardness was set to 0.5%.

いずれの繊維構造体も、低圧領域での硬さは小さく、高圧領域での硬さの増加率が大きいという特徴を有するので、本発明のペット用ベッドのマットに用いるのに好適である。 (result)

Each of the fibrous structures is characterized by having a small hardness in the low pressure region and a large increase rate of hardness in the high pressure region, and is therefore suitable for use in the pet bed mat of the present invention.

In Sample 1 (solid fiber), the reduced thickness and compression rate when compressed at a pressure of 3.4 kPa were 19 mm and 48%, and the reduced thickness and compression rate when compressed at a pressure of 15 kPa were 32 mm and 80%, and in each case, the thickness remains 3 mm or more.

In Sample 2 (laminate), the thickness and compression rate reduced when compressed at a pressure of 3.4 kPa were 18 mm and 46%, and the thickness and compression rate reduced when compressed at a pressure of 15 kPa were 29 mm and 74%. %, and in each case, the thickness remains 3 mm or more.

Further, in the fiber structure having the same density, the fiber structure which is a laminated body of the layer of the solid fiber and the layer of the hollow fiber has a hardness in the low pressure region slightly lower than that of the fiber structure having only the solid fiber. It was shown to be more suitable as the mat of the pet bed of the present invention because it is extremely small and has a higher hardness in the high pressure region.

(Moisture drying)
A fibrous structure composed of thermoplastic fibers can be excellent in water-drying property, and is therefore suitable as a constituent material of a mat for a pet bed. In particular, when the fibrous structure is composed of thermoplastic fibers that are not hydrophilic, a mat that can be washed with water and has excellent dryness can be obtained.

When the mat which is excellent in washing and drying properties is detachably fitted to the frame, the mat which is easily soiled can be detached from the frame and only the mat can be washed, and the mat is excellent in drying property. Therefore, there is an advantage that it is possible to shorten the time when the dog cannot use the bed for washing and drying the bed.

Further, the mat cover constituting the mat can also be made of a material excellent in washing and drying properties. For example, when the mat cover is made of a fabric made of thermoplastic fiber, particularly when made of a net-like fabric, it is excellent in washing and drying properties, and also has excellent breathability and liquid permeability. It has excellent water resistance and liquid permeability, so even if liquid excrement such as urine leaks for the pet, the surface of the mat is hard to get wet, and the pet in contact with the mat does not easily get damp, so if the pet only feels good on the bed In addition, since the mat is excellent in washing and drying even when the mat is soiled, the feeling of use can be excellent for both the owner and the pet.
