Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a composite structure in which a unit frame body is removably connected to the outer periphery of a pine main body, which is formed by removably connecting rectangular unit pine bodies adjacent to each other. Regarding resin mats.

[Prior Art and Problems to be Solved] Conventionally, a plurality of unit mat bodies made of synthetic resin are provided with protruding connecting protrusions on the periphery in order to be placed in places of various sizes and shapes. Various types of mats are constructed by connecting them. In that case, in order to prevent the connecting protrusion from appearing on the outer peripheral edge of the mat and the unit mat members from warping, a unit frame made of synthetic resin can be detachably connected to the outer peripheral edge of the connected unit mat members. Sometimes I do. In this case, it goes without saying that the connection should be easy and reliable, and should have sufficient connection strength.

Japanese Utility Model Application Publication No. 58-64267 discloses that a rod-shaped upright portion 141 of an L-shaped mounting portion provided on a band-like frame is fitted into a fitting hole drilled in the peripheral edge of the mat main body. A configuration is disclosed in which the devices are attached and connected. However, since such a connection configuration is a so-called point-to-point connection, a large number of connection points are required for reliable connection, and the connection work requires time and effort. Moreover, the connection strength cannot be made very high.

In addition, among such connected mats, especially in damp places such as dishwashing areas, laundry areas, and the boundary between indoors and outdoors, water brought onto the mats by washing water or from shoes, umbrellas, etc. from outside can be used. In order to cut the
A large number of through holes may be provided in the top plate of the unit mat body. However, if such water accumulates on the mounting surface on the inside of the mat through the holes, the accumulated water may splash when the user steps on the mat, wetting or staining shoes, clothes, etc. This may cause some inconvenience. Further, such a connected mat may be washed using a detergent while being placed on a placing surface. In that case, if the drainage performance is poor, the removal of bubbles will also be poor and the cleaning work will not progress.

In order to drain water from the inside of the mat, there are measures such as letting water flow to the outside of the mat through the mounting surface of the unit frame located on the outer periphery, or opening a drainage hole in a part of the mat mounting surface. However, unless there is sufficient water flow between the inner parts of the unit mat members and between the inner parts of the unit mat members and the unit frame, effective drainage cannot be achieved. Furthermore, it is of course impossible to sacrifice the strength and rigidity of the pine for drainage.

Japanese Utility Model Publication No. 49-5865 discloses a method for improving water drainage by providing a cut in a part of the frame edge on the outer periphery of the bottom surface of a synthetic resin mat. However, this relates to a single mat body, and the connection mat is easy and reliable, has sufficient connection strength, and has sufficient water flow between the inner parts of the unit mats to be connected. No means have been shown to achieve this.

The present invention was developed in view of the above-mentioned problems existing in the prior art, and its purpose is to facilitate the connection between unit mat bodies and the connection between unit mat bodies and unit frames. Along with ensuring that
While ensuring sufficient strength and rigidity as a mat, it achieves a drainage effect by realizing sufficient water circulation between the inner parts of the connected unit mat bodies and between the unit mat bodies and the unit frame body. The purpose of the present invention is to provide a synthetic resin mat that can be

[Means for Solving the Problems] In order to achieve the above object, the synthetic resin mat of the present invention has a top plate portion 101 having a large number of through holes a, and a top plate portion 101 that is placed on the mounting surface 11. A rectangular unit mat body 1 made of synthetic resin having support parts 102 and 103 that are supported upward, and top plate parts 701, 702, 703, and the top plate parts 701, 702, 703 are placed thereon. An outer periphery of a mat main body, which has a unit frame 7 made of synthetic resin and has support parts 10 and 71 supported above a surface 11, and a plurality of unit mat bodies 1 are removably connected adjacent to each other. The mat is made of synthetic resin and has a unit frame 7 removably connected thereto, and a groove-shaped recess 92 is provided on a side of the unit frame 7 adjacent to the main body of the mat, parallel to that side and opening upward. It has a frame protrusion 9 constituting the four sides 3, 3', 5,
5' has a frame fitting part 6 that fits into the frame protrusion 9 of the unit frame 7 from above, and the unit mat body 1 has two adjacent sides 3, 3' at corresponding positions. A mat body fitting part 4 having a mat body protrusion 2 forming a groove-shaped recess 22 parallel to the sides 3 and 3' and opening upward, and fitting into the mat body protrusion 2 from above, The unit mat body 1 has two adjacent sides 5 and 5', and the unit frame body 7 has a housing part 8 on the side adjacent to the mat main body which can accommodate the mat body protrusion 2, and the frame The body protrusion 9 has a groove-shaped drainage portion 9 with a downward opening that communicates the inner side of the unit frame body 7 and the inner side of the unit mat body 1 at the bottom in contact with the mounting surface 11.
1, and the mat body protrusion 2 has a bottom portion in contact with the mounting surface 11, which communicates the inner side of the unit mat body 1 with the adjacent unit frame 7 or the inner side of the unit mat body 1. It has a groove-shaped draining portion 21 with a downward opening.

[Function] The rectangular unit mat body 1 has mat body protrusions 2 forming groove-shaped recesses 22 that are parallel to each side and open upward at positions corresponding to two adjacent sides 3 and 3'. Mat body fitting parts 4 that fit into the mat body protrusion 2 from above are provided at corresponding positions on the remaining two adjacent sides of the unit mat body 1. Since the fitting between the mat body protrusion 2 and the mat body fitting part 4 is, so to speak, a wire-to-wire connection, the number of connection points can be reduced and the work is easy. Therefore, among the sides of the unit mat body 1 placed on the mounting surface 11, the sides 3 and 3' having the mat body protrusions 2 (hereinafter referred to as protrusion side) are attached to the unit mat bodies to be connected. 1, the sides 5 and 5' without the mat body protrusion 2 (hereinafter referred to as
It is called a non-projecting edge. ) are adjacent to each other, and by fitting the mat body protrusion 2 and the mat body fitting part 4, the unit mat bodies 1 can be easily and reliably connected one after another as necessary to form the mat main body. can be formed.

On the side of the unit frame body 7 adjacent to the mat main body, there is a frame protrusion 9 constituting a groove-like recess 92 that is parallel to that side and opens upward, and on the four sides of the unit mat body 1, Since it has the frame fitting part 6 that fits into the frame protrusion 9 of the unit frame 7 from above, the frame fitting part 6 and the frame protrusion of the unit frame 7 on the outer peripheral edge of the mat main body are connected to each other. By fitting the parts 9 together, the main body of the mat and the unit frame 7 can be reliably connected, and a synthetic resin mat can be easily formed. Since the fitting in this case is also a connection between wires, the number of connection points can be reduced as well, and the work is easy.

In order to reliably connect the unit mat bodies 1 as described above, it is necessary that the length of the mat body protrusion 2 in the sides 3 and 3' direction is sufficient, and the unit mat bodies constituting the main body of the mat In order to reliably connect the unit frame 7 to the body 1, it is necessary that the length of the frame protrusion 9 in the side direction is sufficient.

Half of the outer peripheral edge of the main body of the mat is connected to the unit frame 7 at the non-projecting sides 5 and 5' of the unit mat body 1, and the remaining half is connected to the projecting side 3 of the unit mat body 1. , 3' are connected to the unit frame 7.

In the part of the adjacent line p where the projecting sides 3, 3' of the unit mat body 1 and the unit frame body 7 are adjacent, the frame fitting part 6 of the unit mat body 1 and the frame body of the unit frame body 7 are connected to each other. The protrusion 9 is fitted, and the mat body protrusion 2 of the unit mat body 1 is accommodated in the housing portion 8 of the unit frame body 7. Therefore, both the frame body protrusion 9 and the mat body protrusion 2 are located on this adjacent line p, and their proportion to the length of the adjacent line p becomes high. Therefore, this adjacent line p
It is difficult to achieve a sufficient draining effect by allowing water to flow between the inner part of the unit mat body 1 and the inner part of the unit frame body 7 using only the parts other than the frame body protrusion 9 and the mat body protrusion 2. be. For example, if downward opening cuts of sufficient size are provided on the protrusion sides 3, 3' of the unit mat body 1 and the side of the unit frame 7 along the adjacent line p, respectively, so as to face each other, Although it becomes possible for water to flow, there is a high possibility that the strength and rigidity of the mat will be insufficient. Moreover, in order to increase the reliability and connection strength of the connection between the unit mat body 1 and the unit frame body 7 and the connection between the unit mat bodies 1, the side length of the mat body protrusion 2 and the length of the frame body protrusion 9 are determined. If the length in the side direction is increased, the difficulty becomes even higher.

However, the frame body protrusion 9 and the mat body protrusion 2, which occupy a large proportion of the adjacent line p, have draining portions 91 and 21 at their bottoms that are in contact with the mounting surface 11, respectively. The space surrounded by the mounting surface 11 forms a so-called drainage tunnel that directly communicates the inner side of the unit mat body 1 and the inner side of the unit frame 7, so that the drain section 9
1 and 21, water can flow directly between the inner side of the unit mat body 1 and the inner side of the unit frame body 7, thereby achieving a sufficient water draining effect while maintaining the strength and rigidity of the mat. It becomes possible to list the following. Even when the length in the side direction of the mat body protrusion 2 and the length in the side direction of the frame body protrusion 9 are increased, the size of the draining portion can be increased accordingly to ensure a sufficient draining effect.

In the part of the adjacent line q where the non-projecting sides 5, 5' of the unit mat body 1 and the unit frame body 7 are adjacent, the frame fitting part 6 of the unit mat body 1 and the frame body of the unit frame body 7 are adjacent to each other. The protrusion 9 is fitted. The frame protrusion 9 that crosses this adjacent line q has a draining portion 91 at the bottom in contact with the mounting surface 11, and the draining portion 91 and the mounting surface 1
1 forms a drain tunnel that directly communicates the inner side of the unit mat body 1 and the inner side of the unit frame body 7, so that the drain section 91
Water can be directly circulated between the inner side of the unit mat body 1 and the inner side of the unit frame body 7 through the
This makes it possible to maintain sufficient strength and rigidity as a mat while also achieving a draining effect. Furthermore, even when the length of the frame protrusion 9 in the side direction is increased, the size of the draining portion can be increased accordingly to ensure a sufficient draining effect.

In the main body of the mat, the sides 3, 3' with protrusions and the sides 5, 5' without protrusions of the unit mat bodies 1 are adjacent to each other. In the portion of this adjacent line r, the mat body fitting part 4 and the mat body protrusion 2 are fitted. The mat body protrusion 2 that crosses this adjacent line r is located on the mounting surface 11.
It has a draining part 21 at the bottom in contact with the draining part 21, and the space surrounded by the draining part 21 and the mounting surface 11 forms a draining tunnel that directly communicates the inner parts of the adjacent unit mat bodies 1. Therefore, water can be directly circulated between the inner parts of the unit mat bodies 1 through the drainage part 21, thereby achieving a drainage effect while maintaining sufficient strength and rigidity as a mat. can. Further, even when the length of the mat body protrusion 2 in the side direction is increased, the size of the draining portion can be increased accordingly to ensure a sufficient draining effect.

As a specific example of the procedure, the unit matte body 1 is
Let us consider the case where a square pine main body is formed using two sheets.

In the example shown in FIG. 11, (a) mat body protrusion 2
Place the first unit mat body 1 on the mounting surface with the unit mat body 1 protruding forward and to the right, and (b) place the second and third unit mat bodies 1 on the front and right side of the first unit mat body 1. A unit mat body 1 is placed from above with the direction of the mat body protrusion 2 being in the same direction as the first unit mat body 1, and each mat body protrusion in the first unit mat body 1 is placed. In part 2, the second and third unit matte bodies 1
The respective mat body fitting parts 4 are fitted and connected.
(c) Next, place the fourth unit mat body 1 to the right front of the first unit mat body 1 so that the direction of the mat body protrusion 2 is the same as that of the first unit mat body 1. The mat body fitting portions 4 of the fourth unit mat body 1 are fitted into the respective mat body protrusions 2 of the second and third unit mat bodies 1. Connect to form a pine main body. (d) Next, the frame fitting portion 6 around the mat main body and the frame protrusion 9 of the unit frame 7 are fitted to connect the unit frame to the mat main body.

In the example shown in FIG. 12, (a) mat body protrusion 2
Place the first unit mat body 1 on the mounting surface with the unit mat body 1 protruding forward and to the right, and (b) place the first unit mat body 1 on the right side and the second unit mat body 1 on the right side. , the mat body protrusion 2 is placed from above in the same direction as the first unit mat body 1, and the mat body protrusion 2 on the right side of the first unit mat body 1 is placed.

A synthetic resin mat can be easily formed by reliably connecting the body 7 with the body 7.

(Draining effect) As shown in FIG. 10, in the part of the adjacent line p where the projecting sides 3, 3' of the unit mat body 1 and the unit frame 7 adjoin, the frame fitting part 6 and the frame protrusion 9 of the unit frame 7 fit together, and the mat body protrusion 2 is accommodated in the housing part 8 of the unit frame 7. and the mat body protrusion 2 are both located. The frame body protrusion 9 and the mat body protrusion 2, which occupy a large proportion of this adjacent line p, have draining portions 91 and 21 at their bottoms that are in contact with the mounting surface, respectively. It is possible to allow water to flow directly between the inner part of the unit mat body 1 and the inner part of the unit frame body 7 through the space surrounded by the surfaces, thereby preventing water from impairing the strength and rigidity of the mat. This makes it possible to achieve a sufficient draining effect without having to cut the size for draining.

At the part of the adjoining line q where the non-projecting sides 5, 5' of the unit mat body 1 and the unit frame 7 are adjacent, the frame fitting part 6 and the frame protrusion 9 of the unit frame 7 fit together. together,
The mat body fitting part 4 and the accommodating part 8 are opposed to each other. Water can flow between the inner side of the unit mat body 1 and the inner side of the unit frame body 7 through the mat body fitting part 4 and the housing part 8 which face each other across the adjoining line q, and Frame protrusion 9 crossing adjacent line q
Water can be directly circulated between the inner side of the unit mat body 1 and the inner side of the unit frame body 7 through the space surrounded by the draining part 91 and the mounting surface, which has a sufficient draining effect. can be mentioned.

In the main body of the mat, the sides 3, 3' with protrusions and the sides 5, 5' without protrusions of the unit mat bodies 1 are adjacent to each other. In the portion of this adjacent line r, the mat body fitting part 4 and the mat body protrusion 2 are fitted, and the frame body fitting parts 6 are opposed to each other. Water can flow between the inner parts of adjacent unit mat bodies 1 through the frame fitting parts 6 facing each other across the adjacent line r, and the frame protrusion 9 crosses the adjacent line r. Water can be directly circulated between the inner parts of the unit mat bodies 1 through the space surrounded by the draining part 91 and the mounting surface, and a sufficient draining effect can be achieved.

As described above, water brought through the through hole a of the unit mat body 1, the through hole b of the unit frame body 7, etc. passes through the drainage parts 21, 91, etc., and flows between the inner parts of the unit mat body 1 and the unit mat body 1. and the inner side of the unit frame body 7, and flows from the drainage cavity 12 to the outside of the synthetic resin mat through the placement surface of the unit frame body 7, or flows to the outside of the synthetic resin mat. By flowing down to a drainage hole opened in a part of the surface, water is prevented from accumulating on the mounting surface on the inner side of the unit mat body 1 or the unit frame body 7.

Comparative Test The synthetic resin mat of this example and the drainage parts 21 and 9 in the mat body protrusion 2 and the frame body protrusion 9
The upper surface of both the example pine and the comparison pine with the same configuration except that 1 was blocked was washed with a detergent using a brush while placed on a concrete surface, and then rinsed with water. In the example mat, the foam ran out quickly, but in the comparative mat, the foam caused by the detergent did not disappear easily, and the rinsing process took a long time.

Through this comparative test, it was confirmed that the mats of the examples were able to quickly remove bubbles, allowing efficient rinsing after washing, and that they had good drainage performance as a cause of the rapid removal of bubbles. was completed.

[Effects of the invention] In the synthetic resin mat of the present invention, cuts for draining are provided at corresponding positions in the mat bodies, etc. to be connected, and for example, a rod-shaped upright part is provided on one side of the mat bodies, etc. to be connected, and the other side Instead of draining and connecting by providing a fitting hole to fit into the mat, a frame protrusion/mat having a draining part at the bottom of one of the unit mat bodies or the unit frame to be connected is used. By simply providing a body protrusion and a frame fitting part, a mat body fitting part, or a housing part on the other side, connection can be easily and reliably achieved, and at the same time, the strength and rigidity of the mat will not be impaired. This system simultaneously functions as a drainer while avoiding water leakage, and prevents water introduced through the through holes of the unit mat bodies from accumulating on the mounting surface inside the unit mat bodies.

That is, the rectangular unit mat body has mat body protrusions at corresponding positions on two adjacent sides, has mat body fitting parts at corresponding positions on the other two adjacent sides, and has mat body protrusions on each side. Since the mat body fitting part fits into the mat body protrusion from above, the unit mat bodies can be easily and reliably attached one after another as needed. They can be connected together to form a pine main body. Further, on the side of the unit frame adjacent to the mat main body, there is a frame protrusion that is parallel to that side and constitutes a groove-shaped recess that opens upward, and on the four sides of the unit frame, Since it has a frame fitting part that fits into the frame protrusion from above, it is possible to reliably connect the mat main body and the unit frame to easily form a synthetic resin mat. In either case, the connection between wires is achieved by fitting the protrusion that makes up the groove-shaped recess and the fitting part, so the connection can be made reliably with little effort, and it is also easy to increase the connection strength. It is.

In addition, the space surrounded by the draining parts and the mounting surface of the frame body protrusion and the mat body protrusion may directly connect the inner parts of the unit frame body and the unit mat body or the inner parts of the unit mat bodies to each other. Since a communicating drainage tunnel is formed and a drainage effect is achieved, it is avoided to provide drainage cuts, etc. on each side of the unit mat body or unit frame body to the extent that it may impair the strength and rigidity of the mat. be able to. In particular, for the part of the unit mat body where the side having the mat body protrusion and the unit frame adjoin, the mat body protrusion and the frame body protrusion, which account for a high proportion of the length of the adjacent line, are respectively drained. Because of this, it is possible to maintain the strength and rigidity of the pine while achieving a sufficient draining effect. Furthermore, even if the length of the pine body protrusion or the frame body protrusion is increased in the side direction to increase the reliability of the connection, the size of the draining part can be increased accordingly to ensure a sufficient draining effect. .
