Description

[Detailed Description of the Invention] The present invention relates to a synthetic resin mat that is new and has great industrial applicability.

Conventionally, a suitable number of rectangular sectioned pine mats, each consisting of a large number of pillars erected at equal intervals on the lower surface of the substrate and grasses arranged in rows over the entire upper surface of the substrate, are connected adjacently with a slight gap between them. Synthetic resin mats are well known.

In the synthetic resin mat having such a structure, the adjacent rectangular section mats are connected by a plurality of connecting posts that are integrally erected between the back ends of the respective substrates, and the connecting posts are In the upper part, a groove is carved in the axial direction of the gap between the adjacent square section pine, which absorbs the expansion and contraction of the square section pine due to temperature changes due to seasonal changes and prevents deformation of the entire pine. It is also known to provide for winding of the mat.

However, the square section pine expansion/contraction absorption structure using the grooves of the connecting struts has a structural limit because the connecting struts themselves are made of synthetic resin and generate resistance to deformation. The expansion and contraction of such a square section pine, which has a large number of square sections, does not occur uniformly in one direction; in reality, it deforms not only horizontally but also vertically, and the deformation is different for each square section pine. Taking this into consideration, there is a great possibility that the expansion and contraction of the square section pine cannot be completely absorbed, and the entire pine will be bent, and in addition, the connecting struts will become weak due to the grooves carved on their top surfaces. In particular, when the adjacent square section mat contracts and the groove expands, strong stress concentration occurs at the bottom of the groove of the connecting strut, which may cause damage when stepped on by a shoe.

The object of the present invention is to completely eliminate the drawbacks of this type of pine described above by means of a new construction.

Next, the configuration of the present invention will be specifically explained with reference to the drawings showing one embodiment.

Reference numeral 1...1 is a rectangular section mat in which a large number of supports 3...3 are erected at equal intervals on the bottom surface of the substrate 2.
It has a known configuration in which grass blades 4...4 are arranged in rows over the entire upper surface, and the drawings show an embodiment in which the substrate 2 is constituted by a large number of crosspieces 21...21 in a lattice shape and a cross shape. Note that 5...5 are auxiliary supports that are erected on the periphery of the lower surface of each board 2.

6...6 is a plurality of connecting bands which form the essential part of the present invention, and are connected to the square section mats 1...
Adjacent rectangular section mats 1...1 in the case where a desired unit mat shape is constructed in which an appropriate number of mats 1 are arranged adjacently with some gaps 7...7 between them.
are integrally connected at equal intervals, and the substrate side end 22 of one of the adjacent square compartment mats 1, 1 having a gap 7 between them.
An end extending horizontally from the upper part to the center of the cavity 7 is slightly extended downwardly from the lower end of the substrate 2,
The hanging end 61 is raised in a U-shape and is connected to the lower part of the corresponding board side end 22, so that the square section mats 1...1 and the connecting band 6 shown above are connected to each other.
...6 is integrally molded from soft synthetic resin,
This constitutes the unit mat 8 in the present invention.

9...9 are known connecting cylinders protruding from two consecutive sides of the unit mat 8, and 10...10 are:
The synthetic resin mat of the present invention is a known connecting body that protrudes from the other two continuous sides of the unit mat 8 and can be inserted into and removed from the connecting tube 9. A plurality of these connecting tubes 9...
9 and connecting bodies 10...10 are connected in an appropriate shape.

In the inventive pine, the square section pine 1...
1 is connected by a connecting band 6...6 to form a unit mat 8
Since the connecting bands 6...6 have a bending structure as shown in FIG. Therefore, the expansion and contraction can be completely absorbed very easily and reliably, and there is no risk of the pine bending due to the insufficient expansion and contraction absorption of the square section pine, which is seen in conventional pine of this type. Not only does it have a special effect in that respect, but it can also completely overcome the problems associated with stress concentration or lack of strength of the connecting struts, as described above, in conventional mats that use connecting struts.
Coupled with the fact that it can be manufactured at a low cost, it has great industrial applicability.

In particular, each of the connecting bands 6...6 has one end extending horizontally from the upper part of the substrate side end 22 of one of the rectangular mats 1 to the center of the cavity 7 between the adjacent rectangular mats 1, 1. and the other end is the hanging end 6
1 in a U-shape and connected to the lower part of the corresponding board side end 22, and the connecting directions of both ends are perpendicular to each other, so that although the connecting bands 6...6 themselves are made of synthetic resin, Even if the direction and amount of deformation differ depending on each square section mat 1...1,
Unlike a device in which both ends are connected in one direction, it is possible to effectively absorb such deformation and minimize its influence.
