Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a lattice-shaped mat used, for example, as an entrance mat or a gutter cover.

<Background of the invention> Conventionally, as this type of lattice-shaped mat, there is one in which a plurality of metal bars are arranged in parallel by forming or pultrusion and are connected together. However, in the case of forming bar material for this type of pine, each component such as a horizontal tread surface and a ground surface is formed in series on the top and bottom of a vertical support wall on one strip-shaped metal plate, and each component is The plates have the same thickness, so the strength and elasticity of each component cannot be changed. In addition, in the case of aluminum pultrusion, although the wall thickness of each component can be varied, it is not possible to provide elastic parts.

<Purpose of the invention> The object of the present invention is to provide a novel lattice-shaped pine that has an extremely simple configuration and allows the strength and elasticity of the pine surface and vertical support walls to be freely set according to the application.

<Structure and Effects of the Invention> In order to achieve the above object, this invention is a pine in which a plurality of bar members are arranged in parallel and integrally connected, and a flat receiver is provided on the upper part of the bar member over the entire length. A metal cover is fitted to this receiving part.

According to the above structure, this invention has a composite structure in which a metal cover is fitted to the flat receiving part of the upper part of the bar material, so the constituent material of the bar material is selected according to the application of the lattice pine, and the bar material is By adjusting the wall thickness of the material and the metal cover, the practical effect of achieving the purpose of the invention can be achieved.

<Description of Embodiments> The drawings show a lattice-shaped mat 1 according to the present invention.
The lattice-shaped mat 1 is formed by disposing a plurality of bar members 2 in parallel and connecting them together at two or more points along the entire length.

The bar material 2 is formed by forming a band-shaped metal plate such as a stainless steel plate, and has a supporting part 21 at the bottom with both ends folded and overlapped, and a supporting part 21 in which the central parts of the supporting parts 21 are bent upward and joined together. wall 2
2. A flat receiving part 23 is formed on the upper part of the support wall 22, which is bent outward from each other, and shaft holes 24 are provided in several places in the support wall 22, and a cylindrical space is formed in the shaft hole 24 portion of the adjacent bar material 2. A seat 3 is interposed therebetween, and a connecting shaft 4 passes through the seat 3 and is integrally connected thereto.

In the present invention, a separately formed metal cover 26 is fitted to the receiving part 23 of the bar material 2 to form a composite structure.
Similar to the bar material 2, the bar material 2 is made by applying a forming process to a band-shaped metal plate made of stainless steel, etc., and folding both edges downward to form an engagement groove in which the receiving portion 23 of the bar material 2 engages. It is engaged with and integrally connected to the receiving portion 23 of the material 2 from one end. The band-shaped metal plates constituting the bar material 2 and the cover 26 are used depending on the application of the lattice pine 1, for example, when a vertical static pressure load is applied to the pine surface, when a strong load due to sideslip is applied, or when no load is applied at all. If this does not work, one of the plates may be made thicker or both plates may be made to have the same thickness depending on the conditions.

FIG. 4 shows another embodiment of the bar material 2. In this embodiment, a forming process is applied to a band-shaped metal plate similar to the above-mentioned example, and the upper parts of the support walls 22 whose lower parts are folded and joined are bent forward and backward to form a flat receiving part 23. metal cover 26 similar to
are engaged. In this case, the weight of the mat can be reduced by simplifying the structure of the bar material 2.

FIG. 5 shows another embodiment of the bar material 2, in which the top and bottom of the vertical support wall 22 are bent to one side with the top and bottom facing each other.
Receiving parts 23, 23a are formed by bending the outer edges inward to protrude to the opposite side, and metal covers 26, 26a are engaged with the upper and lower receiving parts.

In the embodiment shown in FIG. 6, horizontal receiving parts 21 and 23 are integrally formed on the upper and lower sides of a vertical support wall 22, respectively, by extrusion molding the bar material 2 of aluminum or other metal material or synthetic resin material. Upper receiver part 2
3 is engaged with a metal cover 26 similar to the above example. In this example, depending on the pine that requires high rigidity or the pine that requires elasticity,
The bar material 2 is made of a metal material or a synthetic resin material.

In the embodiment shown in FIG. 7, the bar material 2 is formed by extrusion molding of aluminum or synthetic resin material as in the previous example, and a horizontal receiving part 23 is provided on the upper part of the vertical support wall 22. This receiving part 23 is located in the center of the upper surface of the
A smaller width receiving portion 23a is integrally formed, and a metal cover 26 is engaged with the receiving portion 23a. In this case, the bar material 2 is colored aluminum, and the metal cover 2 is
By making 6 a polished stainless steel plate, a lattice surface with a unique color can be obtained, which improves the luxury of the pine.

As described above, the present invention is a mat in which a plurality of bar materials 2 are arranged in parallel and integrally connected.
Since the flat receiving part 23 is formed on the upper part of the mat and the metal cover 26 is integrally engaged with the flat receiving part 23, the mat has a composite structure of the bar material 2 and the cover 26, so the structure of the bar material can be adjusted according to the application of the mat. By selecting the material and setting the wall thickness of the bar material 2 and the cover 26, it is possible to provide high rigidity to the pine surface and elasticity to the supporting wall, which simplifies the structure and has many practical effects. are doing.
