Description

[Detailed description of the invention] [Field of application and overview of the invention] The present invention relates to a drainboard for baths, and in particular relates to a drainboard having a structure in which a large number of strip-shaped bases of a constant width and length are connected in parallel. The connecting member that connects the base bodies to each other allows the entire body to not bend at the connecting portion, and moreover, it can be folded into a small size when being transported.

[Prior art and its problems] There is a grid plate constructed by connecting a plurality of strip-shaped plate members, which is disclosed in Japanese Utility Model Application Publication No. 48-29616. It has a structure in which engaging connecting plates are provided at the front and rear. In this case, since the connecting plate is only loosely fitted and engaged with the side wall of the base body, there is an advantage that the drainboard can be completed by connecting the base bodies manufactured in advance with the connecting plate. However, in this conventional method, since the fitting portion of the connecting plate can be bent within a certain range, there is a problem in that the entire drainboard does not form like a single plate in the connected state, making it difficult to use. Furthermore, there is a problem in that the substrates are unstable because they bend each other during use. Furthermore, although the bases can be bent within a certain range, since the bending range is narrow,
Another problem is that it cannot be folded during transportation.

The present invention has been made in view of this point, and is a ``slatted grid in which a plurality of elongated plate-shaped base bodies 1 are connected by a connecting means,'' in which the entire unfolded state is in a firm and uniform state. It becomes a plate shape,
The challenge is to make it foldable when transporting it.

[Technical Means] The technical means of the present invention taken to solve the above problem is as follows: ``The upper part of the side wall of the base body 1 and the side wall facing the adjacent base body 1 has an arc-shaped cross section and is open laterally. An engagement groove 13 is formed in the entire longitudinal direction of the base 1, and an engagement groove 14 that opens downward is formed in the lower part of the side wall in the entire longitudinal direction of the base 1. The connecting means interposed therebetween is a connecting bar 2 having a uniform cross section and a length that substantially matches that of the base body 1, and the cross-sectional shape of this connecting bar 2 has a size that matches the connecting interval between the base bodies 1, 1. The hollow main body portion 21 has a shape in which shaft portions 22, 22 protrude from both ends of the upper surface and engaging pieces 23, 23 protrude from both ends of the lower surface, and the shaft portion 22 and the engaging groove portion 13 are made a cylindrical pair. The mating piece 23 is inserted into the engaging groove portion 1
4 is engaged in a one-way manner to prevent it from coming off, the connecting bar 2 is made of an elastic material, and at least a pair of ribs 12, 12 are made to protrude from the back surface of each base body 1.

[Operation] The above technical means of the present invention operates as follows.

The mutually opposing side walls of the base bodies 1, 1 have their upper engaging grooves 13, 13 cylindrically coupled to the shaft portions 22, 22 protruding from both sides of the connecting bar 2, so that these portions are connected to each other in a manner that prevents them from coming off. Ru. On the other hand, the base 1,1
The lower portions of the mutually opposing side walls are one-way engaged with the engagement pieces 23, 23 protruding from both sides of the connecting bar 2 so that the engagement grooves 14, 14 are prevented from coming off. Further, the size of the main body portion 21 is made to match the connection interval between the base bodies 1, 1. Therefore, in this connected state, the bases 1, 1
Since the upper and lower parts of the mutually opposing side walls are connected in a manner that prevents them from coming off, these base bodies 1, 1 are connected in such a manner that they do not bend.

Furthermore, the connecting piece 2 is made of an elastic material, and the engaging piece 23 is one-way engaged with the engaging groove 14 that opens downward.
By bending downward, the engagement can be forcibly released. On the other hand, since the lower portions of the side walls of the base bodies 1 and 1 are in a cylindrical pair with the shaft portion 22, the engaging piece 23
By releasing the engagement, the base bodies 1, 1 can rotate about the shaft portion 22 as a fulcrum. Therefore, the base bodies 1, 1 can be folded together by the above operation.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

In the unfolded state, the base bodies 1 and 1 are connected to each other in an unfoldable state, so that when in use the drainboard is in an integrated state as a whole, which is convenient to use. Moreover, since the base bodies 1 and 1 can be folded together by releasing the engagement of the engagement pieces 23 as necessary, handling when carrying is easy.

The base bodies 1, 1 are connected to each other in an unfoldable state, and each base body 1 has a pair of ribs 12, 1 on the back surface.
2, the top surface of the drainboard becomes stable during use.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.

In this embodiment, as shown in FIG. 1, a configuration is adopted in which the slatted base bodies 1, 1 are connected by a connecting bar 2, and both are made of extrusion molded products.

As shown in FIG. 2, the surface of the slatted base 1 has an uneven rough surface 1 having a grain pattern, a polka dot pattern, etc.
1 is formed, and ribs 12, 12 extending in the longitudinal direction are provided protruding from the back surface.

Furthermore, a fitting part that fits with the connecting bar 2 is formed on the side surface, and this fitting part has a shaft groove part 13 that fits around a part of the connecting bar 2 in a paired state, and the other part of the connecting bar 2. It consists of an engagement groove part 14 that the part engages with.

The slatted base 1 is manufactured by cutting a long material made by extrusion molding into a certain size as shown in FIG. It has an uneven rough surface formed by pressing a predetermined roller 5 on the surface.

For this reason, a predetermined uneven rough surface is formed on the surface of the roller 5, and when this roller is pressed against the surface of the uncured material and the material is cured, it becomes a predetermined elongated material.

Next, the connecting bar 2 is formed so that its cross section is symmetrical as shown in FIG. 2, and has a hollow main body 2.
A shaft portion 22 and an engaging piece 23 protrude from both sides of the shaft portion 1 . In this device, the shaft portion 22 is located at the upper end of the main body portion 21, and the engagement piece 23 is located at the lower end of the main body portion 21. Further, these shaft portions 22, 22 are fitted into the shaft grooves 13 of the facing grating base 1, and the engaging pieces 23, 23 correspond to the engaging grooves 14 formed on the lower surface of the grating base 1.

In the above embodiment, the shaft portion 22 and the shaft groove portion 13
Since they are rotatably connected to each other, each slatted base body is connected to be foldable around this fitting portion. Therefore, when transporting or carrying it, it must be folded as shown in Figure 4.

When in use, this folded state is unfolded, and the already unfolded connecting portion engages with the engagement groove 14 of the grating base 1 where the engagement pieces 23, 23 face each other, as shown in FIG. On the other hand, the engaging pieces 23, 23 of the connecting bar 2 of the folding portion, which are in a free state due to unfolding, similarly engage and lock with the opposing engaging groove portions 14, 14.

In this unfolded state, that is, in the engaged lock state, both the upper shaft portion 22 and the lower engaging piece 23 of the connecting bar 2 are in a state where they are prevented from coming off in the connecting direction, so that the connecting portion is not bent. The unfolded state is firm and stable during use. Therefore, even when a person rides on the vehicle, there is no sense of instability caused by bending at the joints.

In addition, as in the illustrated embodiment, ribs 24 are formed on the lower surface of the connecting bar 2, and the ribs 12 and 1 of the slatted base 1 are
If it is set to the same height as 2, the above effect will be further improved.
