Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a synthetic resin mat that is used for bathrooms, shoe wipes, etc. and has an extremely efficient connecting structure of unit substrates.

[Conventional technology]

Regarding the mechanism for constructing one bathroom/shoe cloth mat body by removably connecting a plurality of synthetic resin unit boards by engaging portions provided on the side walls of the synthetic resin unit boards. , various types have been disclosed in the past.

Among them, the pine connecting device disclosed in Utility Model Application Publication No. 178984/1984 has one side edge of a rectangular flocked board.
A hook-shaped protrusion is provided with the hook on the outside and projects downward, and a protrusion that is slightly shorter than the hook-shaped protrusion is provided on the other side edge so as to protrude downward so as to be slightly inclined outward, so as to surround the protrusion. A rectangular tube slightly taller than the hook-shaped protrusion is attached to the lower surface of the flocking board, with one half of the tube protruding outside the board.

In this connection device, when the hook-shaped projection on one flocking board is pushed into the protrusion of the rectangular tube on the other flocking board from above, the projection is pushed and once bent inward, and when the hook-shaped projection is pushed all the way in, , it returns to its original state and its tip catches on the hook of the hook-shaped protrusion. The back side of the hook-shaped protrusion is supported by the square tube surrounding it and will not bend backwards, so the protrusion will not come off from the hook and both flocking plates will be connected reliably.

[Problem that the invention attempts to solve]

However, with the above-mentioned coupling device, the coupling/
When detachment is repeated, the protrusion that hooks onto the hook of the hook-shaped protrusion and maintains the connection is repeatedly deformed by being pushed, bending inward, and returning to its original shape each time. Become. Therefore, permanent deformation may occur, making it difficult to maintain the connection.

In addition, this coupling device has a protrusion that projects downward so as to be slightly inclined outward, and a rectangular tube is attached so as to surround the protrusion so that one half of the tube protrudes outside the plate. Since it has a very complicated shape, it is difficult to manufacture.

The present invention was developed in view of the shortcomings of the conventional mechanism as described above, and its purpose is to make it easy to connect mats together, and to ensure good connection during connection even if the mats are repeatedly connected and disconnected. To provide a synthetic resin mat which can be manufactured easily without having a complicated structure.

[Means for solving problems]

In order to achieve the above object, the synthetic resin mat of the present invention has an engaging protrusion having an L-shaped cross section on the first side wall of the synthetic resin unit board, and the engaging protrusion on the second side wall. an engaging recess that can be engaged and disengaged in the first side wall; a fitting hole is provided in a portion of the first side wall that faces the engaging protrusion; A pair of pressing protrusions are formed, and a fitting protrusion that can be fitted into the fitting hole when the engaging protrusion and the engaging recess are engaged is formed on the outer surface of the engaging recess. The fitting of the fitting protrusion into the fitting hole is maintained by pressing the back side of the fitting protrusion by the pair of pressing protrusions.

[Effect]

The engagement recess on the first synthetic resin unit board is engaged with the L-shaped engagement protrusion in cross section on the second synthetic resin unit board, and the fitting formed on the outer surface of the engagement recess is engaged. When the mating protrusion is fitted into the mating hole provided in the portion facing the engaging protrusion, the back side of the mating protrusion is pressed by the pair of pressing protrusions on the engaging protrusion. The fitting of the fitting protrusion into the fitting hole is maintained. Therefore, the connection between the two synthetic resin unit substrates is ensured by the engagement between the engagement recess and the engagement protrusion. The fitting protrusion does not simply fit into the fitting hole, but is pressed by the pressing protrusion to maintain its fit, so repeated engagement and disengagement caused permanent deformation in each part. Even in such cases, it is possible to reliably maintain the fit and secure the connection.

Furthermore, when the engagement recess and the engagement protrusion are engaged and disengaged, the engagement protrusion is pressed against the first side wall, and the pressing protrusion that presses the back side of the engagement protrusion is pressed against the first side wall. Since a pair of protrusions are formed at both ends facing the mating hole, the back side of the mating protrusion is not directly pressed, but the pressing protrusions are placed on both sides of the back side of the mating protrusion. The pressure will be applied by the section. Therefore, even though the fitting protrusion is pressed against the first side wall, it is possible to engage and disengage relatively smoothly.

[Example] An example of the synthetic resin mat of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a unit board made of synthetic resin and having a square shape. This synthetic resin unit substrate 1 is usually used by connecting a plurality of them adjacently, but it is also possible to use them singly.

Reference numeral 2 denotes a side wall of the synthetic resin unit board 1; 3 an engagement protrusion projecting from the side wall 2 and having a rectangular shape in front and an L-shape in cross section; the lower part of the side wall 2; A horizontal surface 31 extending further outward is bent upward to form a vertical surface 32, thereby forming the L-shaped cross section.

4, 4 is one side wall 2 facing the vertical surface 32;
The fitting holes 5, 5 and 5, 5 provided at symmetrical positions of the parts are two pairs of pressing holes formed at both ends of the vertical plane 32 facing the fitting holes 4 and 4, respectively. It is a useful protrusion.

6 is one of the square synthetic resin unit substrates 1;
As shown in FIG. 5, the lower part of the other side wall at a symmetrical position or adjacent to the side wall 2 at a position corresponding to the L-shaped engaging protrusion 3 is cut out in a rectangular shape as shown in FIG. An engaging recess 8 is formed having an inverted L-shaped cross section, with the side wall portion having the forming portion 7 serving as a vertical surface 81, and the edge portion of the plate surface of the substrate 1 connected to the vertical surface 81 serving as a horizontal surface 82. Thus, the engagement protrusions 3 and the engagement recesses 8 of the adjacent synthetic resin unit substrates 1, 1 can be freely engaged and disengaged.

Reference numerals 9 and 9 denote fitting portions formed in a vertical surface 81 which is an outer side surface of the engagement recess 8, and when the engagement protrusion 3 and the engagement recess 8 are engaged, the engagement protrusion It can be fitted into the fitting holes 4, 4 drilled in 3.

When the engagement protrusion 3 and the engagement recess 8 are engaged and the engagement protrusions 3, 3 are fitted into the fitting holes 4, 4, the pressing protrusions 5, 5 and 5, 5 lock the fitting together. is held,
The connection between the adjacent synthetic resin unit substrates 1, 1 is ensured by the engagement between the engagement recess 8 and the engagement protrusion 3.

In this embodiment, one engaging protrusion 3 and one engaging recess 8 are formed in the center of one side wall 2 and the other side wall 6, respectively, and the fitting holes 4, 4 have a rectangular shape. Although embodiments are shown, the present invention is of course not limited to these embodiments.

In addition, 10 is a supporting column part for draining water, 11 is a water draining part provided on the engaging protrusion 3, and 12 is a small hole for draining water.

[Effect of idea]

In the synthetic resin mat of the present invention, the fitting of the fitting protrusion into the fitting hole in the engagement of the engagement recess and the engagement protrusion in each of the plurality of mats is such that the back side of the fitting protrusion has one pair. Since it is held by being pressed by the pressing protrusion, it is possible to reliably maintain the fit and secure the connection even if each part is permanently deformed due to repeated engagement and disengagement. Moreover, since the pressing protrusion presses both sides of the back side of the mating protrusion, the mating protrusion can be engaged and disengaged relatively smoothly even though it is pressed against the side wall of the other mat. It is possible to do so. In short, the mats can be easily connected to each other, and even if the mats are repeatedly connected and detached, good connection can be ensured at the time of connection. Further, the structure is not complicated and can be manufactured relatively easily.
