[Industrial applications]

 The present invention relates to a sludge placed on a drainage ditch provided at the edge or bottom of a pool, a washing room, a bathroom, or the like.

[0002]

[Prior art]

 Heretofore, various types of drain member soot members for drainage have been already proposed. For example, in the structure shown in FIG. 7, a through hole is formed in the lower portion of each lattice rod, and a long rubber rod is connected to this through hole and an intermediate ring arranged between the lattice rods. This child member is convenient for storage because it can be rolled up as a whole, but if you want to replace the star rod, you must remove the rubber rod and intermediary ring that connect them. The replacement work is very troublesome.

In order to solve this, for example, Japanese Utility Model Laid-Open No. 59-38586 proposes a lattice stand such as a drainage groove. As described in the claims of the utility model of the above publication, this lattice base has "a large number of lattice rods formed in a substantially U-shaped cross section and a narrow groove in which the leg plates of these lattice rods intervene. A plurality of joints each having a substantially W-shaped cross section, which are formed and in which the recesses are formed in the narrow grooves so as to mate with the notches of the lattice rod, are provided. With this lattice base, when replacing a defective lattice rod, it is sufficient to remove the joint located in the vicinity thereof, so the above-mentioned problem disappears. However, in order to form this lattice base, it is necessary to prepare the lattice rods and the corresponding number of joint members, so that the manufacturing cost is high and it is troublesome to assemble the lattice base. Moreover, since this "lattice base" must connect "a large number of lattice rods", its manufacture is very troublesome.

For this reason, for example, as in “Synthetic resin mat” proposed in Japanese Utility Model Publication No. 1-41346, “a large number of columns are erected at equal intervals on the lower surface of the substrate and the entire upper surface of the substrate is In a synthetic resin mat in which a plurality of unit mats that are connected adjacent to each other with a slight gap between them are detachably connected, Between the adjacent rectangular partition mats 1 and 1, the end extending horizontally in the center of the void 7 from the upper part of the end 22 on the substrate side of one rectangular partition mat 1 hangs slightly below the lower end of the substrate 2. Unit mats 8 ... 8 formed by extending and extending the hanging lower end 61 in a U-shape and integrally connecting them at equal intervals by a plurality of connecting bands 6 ... It is considered to be "having." That is, in this "synthetic resin mat", a "square partition mat" is adopted in place of the "multi-lattice rod" described above, and a plurality of the square partition mats are connected by the connecting band 6. Yes, the above disadvantages of using "a large number of rods" have been eliminated.

However, as shown in FIG. 8, the synthetic resin mat disclosed in Japanese Utility Model Publication No. 1-41346 discloses that “the space between the adjacent square partition mats 1 and 1 is smaller. Substrate-side end 22 An end extending horizontally from the upper part to the center of the void 7 is hung slightly below the lower end of the substrate 2 and the hanging lower end 61 is raised in a U-shape to accommodate the corresponding substrate. Since it is necessary to integrally connect the plurality of connecting bands 6 ... 6 which are connected to the lower part of the side end portion 22 at equal intervals, it is possible to secure the flexibility between both the substrates 2 and 2. However, if, for example, one substrate 2 is to be replaced, the connecting band 6 must be cut, and not only the connection between the two substrates 2 and 2, but also the connection maintaining flexibility between them. It cannot be done.

[0006]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and the problem to be solved is the difficulty in manufacturing and assembling the conventional soot.

The object of the present invention is that the parts can be easily replaced if necessary and can be manufactured at low cost, and the work can be easily performed when assembling. It is to provide a drainage drainboard that can be used.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the means adopted by the present invention will be described with reference to FIGS. 1 to 5 corresponding to the embodiments. A drainage ditch saw having a large number of gaps 16 formed by integrally connecting a large number of rod-shaped main body parts 11 having anti-slip 15 to the surface thereof with a connecting part 12. The engaging portion 13 having the vertical through hole 13a and the engaging step portion 13b adjacent to the engaging portion 13 are integrally formed on the outer surface of the one rod-shaped main body portion 11 located on the outermost side. While being formed, the outer surface of the other rod-shaped main body portion 11 located on the outermost side is thinner than the thickness of the insertion hole 13a so as to be inserted into the insertion hole 13a of the other engaging portion 13 of the drain groove. The formed fitting piece 14 and this fitting piece 1 An engaging projection 14a that is integrally formed at the tip of the engaging step portion 13b and that is engaged with the engaging step portion 13b is integrally formed. It is a drainage drainboard 10 "that is characterized by doing so.

[0009]

[Function of the device]

 The action of the drainage ditch according to the present invention constructed as described above will be explained together with the mode of use thereof. First, this drainage ditch saw is made of, for example, polypropylene as shown in FIGS. The rod-shaped main body portions 11 are integrally formed as ones that are connected to each other by the connecting portions 12, so that the manufacturing is performed, for example, as shown in FIG. It is, of course, much easier than manufacturing one grid rod at a time.

Further, this drainage ditch saw 10 is capable of covering the drainage ditch or the drainage port having the area shown in FIG. 1 by one piece. If it has a smaller area, a part of the connecting portions 12 connecting the rod-shaped main body portions 11 may be cut so as to have an appropriate area before use. In the drainage drainboard saw 10 illustrated in the following embodiment, each rod-shaped main body 11 is connected by the three connecting portions 12, so the above cutting work only cuts the three connecting portions 12. It is very easy because it is completed in.

On the other hand, when the drainage groove is long, for example, as shown in FIG. 6, a plurality of drainage drainboard saws 10 are used by utilizing the respective engaging portions 13 and fitting pieces 14. The drainage ditch boards 10 may be connected as shown in (a) of FIG. 5, for example. That is, first, one drainage ditch saw 10 serving as a reference is placed on the drainage ditch or another flat place, and the engaging portion 13 formed on the side surface of one rod-shaped main body 11 is That is, the fitting piece 14 on the side of the drainage drainboard 10 is forcibly fitted. At this time, the fitting piece 14 is formed so as to expand slightly outward with respect to the rod-shaped main body portion 11, but the fitting piece 14 is formed to have elasticity, and Since the engaging protrusion 14a integrated with the tip is formed as a roundish one, the fitting piece 14 is engaged with the side surface of the rod-shaped main body 11 of the drainage ditch saw 10, which serves as a reference. It is automatically inserted into the insertion hole 13a of the joint portion 13.

The fitting piece 14 inserted into the insertion hole 13a of the engaging portion 13 returns to the expanded state by its own elastic force as shown in FIG. 5B. Since the engaging step portion 13b is formed on the side of the bar-shaped main body portion 11 facing this, the engaging projection 14a of the fitting piece 14 engages with the inside of the engaging step portion 13b and serves as a reference. The connection of another drainage drainboard saw 10 to the drainage drainage grid saw 10 is completed.

As described above, in the drainage drainboard saw 10 connected to the reference drainage drainboard saw 10, the connecting portion 12 is formed on the other outermost rod-shaped main body portion 11. Therefore, when it is desired to connect another drainage drainboard saw 10, the same operation / work as described above may be performed.

In the drain groove ditch saw 10 in which a plurality of rod-shaped main body portions 11 are connected by the connecting portion 12, since the lower surface thereof is a completely flat surface, if the drain groove is placed on a completely flat surface. If not, the drainage drainboard saw 10 may be considered to be somewhat rattled (so-called unsteady phenomenon), but such a problem does not occur so much. This is because each fitting piece 14 is formed thinner than the thickness of the insertion hole 13a, and even when the drain groove saws 10 are connected to each other, the fitting piece 14 and the insertion hole 13a are connected to each other. The reason is that there are a lot of free spaces, and the drainage drainboard saws 10 can be bent to each other in the connecting direction. In addition, since the rod-shaped main body portions 11 are partially connected by the connecting portion 12, so that the rod-shaped main body portions 11 are completely placed on the placement place by the deformation of the connection portions 12, It is also because there is almost no height difference in millimeters at the place where the drain is placed.

Of course, according to the large number of drainage drainboard saws 10 that have been connected and placed as described above, the cleat 15 formed on the surface of the rod-shaped main body portion 11 of each drainage drainage grid saw 10 forms the gap 16. Since they are sandwiched and lined up on the drainage ditch, it is natural that they do not slip when walking on the drainage ditch saw 10. Moreover, it goes without saying that the drainage immediately flows from the gaps 16 into the drainage channels below.

As described above, when the plurality of drainage drainboard saws 10 are connected to each other by the engaging portions 13 and the fitting pieces 14, the engaging protrusions 14 a of the fitting pieces 14 engage with each other on the engaging portion 13 side. By engaging the stepped portion 13b, the vertical relative movement of each drainage ditch saw 10 is restricted, and the fitting piece 14 is inserted into the insertion hole 13a of each engaging portion 13. As a result, the lateral relative movement of the drain ditch boards 10 is restricted, and as a result, the drain ditch boards 10 are firmly connected to each other.

Further, the drainage ditch saws 10 thus connected to each other must be entirely removed from the drainage ditch, for example, when cleaning the inside of the drain ditch. All you have to do is wind along the direction. This is because each fitting piece 14 is formed to be thinner than the thickness of the insertion hole 13a, and even when the drain groove slats 10 are connected, the fitting piece 14 and the insertion hole 13a are not connected to each other. Since there is some free space between them and both drain grate drainboards 10 can be bent with respect to each other in the connecting direction, the drainage grate saws 10 connected to each other are It can be wound along the connecting direction.

When it becomes necessary to replace or remove the drainage ditch saw 10 that is connected and placed on the drainage ditch as described above, the process may be performed as shown in FIG. 4C, for example. That is, between the fitting piece 14 on the drain groove ditchboard 10 side to be removed and the rod-shaped main body 11 of another drainage gutter duckboard 10 adjacent thereto, a detachment plate 17 such as a metal finger is provided. The insertion protrusion 14a of the fitting piece 14 is disengaged from the engagement stepped portion 13b, so that the drain groove ditch saw 10 is pulled up at that time. If the same operation is performed on the other side of the drain ditch saw 10 to be removed, the drain ditch saw 10 is completely removed from the other drain ditch saws 10. Then, if another drain drainboard saw 10 is subjected to the work described above with reference to FIG. 5A, the drainage drainboard 10 can be easily replaced.

【Example】

 Next, the drainage drainboard saw 10 according to the present invention will be described with reference to the embodiment shown in the drawings. FIG. 1 is a bottom view of a lower portion of the drainage drainboard saw 10 according to the present invention from the illustrated center line. A top view is shown. The drainage ditch saw 10 is integrally molded of, for example, a synthetic resin material such as polypropylene, and as shown in FIG. 2, a plurality of rods (10 in this embodiment) having a substantially inverted U-shaped cross section are formed. A plurality of (three in the present embodiment) plate-like connecting portions 12 are connected to each other in a state where gaps 16 are formed at equal intervals. Thus, making each rod-shaped main body 11 substantially U-shaped in cross section and making each connecting portion 12 plate-shaped is a mold for integrally molding the drainage drainboard saw 10 with a synthetic resin material. It is important not only for facilitating molding, but also for ensuring a certain degree of elasticity of the entire drainage ditch saw 10.

Of the rod-shaped main body 11 as described above, the outer surface of one of the rod-shaped main body 11 located on the outermost side of the drainboard drainboard 10 (for example, the rightmost end in FIG. 1) is As shown in FIGS. 2, 3, and (a), and FIG. 5, a plurality of (two in the present embodiment) engaging portions each having an insertion hole 13a penetrating vertically and having a substantially U-shaped cross section. 13 is integrally formed. As shown in FIG. 5, the inner end portion of the engaging portion 13 on the insertion hole 13a side is so-called chamfered in order to guide the engaging protrusion 14a of the fitting piece 14 described later. . Further, as shown in FIGS. 3A and 5 on the outer surface of the rod-shaped main body portion 11 located in the vicinity of the engagement portion 13, that is, in the present embodiment, below the engagement portion 13 in the figure. An engaging stepped portion 13b for engaging the engaging projection 14a of the fitting piece 14 is formed, and the upper end portion of this engaging stepped portion 13b in this embodiment prevents the engaging projection 14a from engaging. To make it easier to perform, it is a step section at a substantially right angle.

On the other hand, the outermost surface of the drainboard ditch saw 10, for example, the outer surface of the rod-shaped main body portion 11 located at the left end in FIG. 1, is shown in FIGS. 2, 3 (b) and 5. In addition, a fitting piece 14 to be engaged with the above-mentioned engaging portion 13 of the drainage drainboard saw 10 is integrally formed. As shown in the left end portion of FIG. 2 and (a) of FIG. 5, the fitting piece 14 has a substantially L-shaped tip (the lower end in the figure) that expands outward when no force is applied. As shown in FIGS. 5 (a) and 5 (b) in detail, the engaging projection 14a that engages with the engaging stepped portion 13b is integrally formed at the tip thereof. It is formed in the. As shown in FIGS. 1, 3B, and 4, the fitting piece 14 has a width that should be substantially entirely inserted into the insertion hole 13a of the engaging portion 13. The engaging projection 14a formed integrally with the tip of the same is also formed to have the same width. The width of the engaging stepped portion 13b on the side of the engaging portion 13 is substantially the same as the width of the engaging protrusion 14a, as shown in FIG.

Each fitting piece 14 is formed to be thinner than the thickness of the insertion hole 13a, as shown in detail in FIGS. As a result, even when the drain groove ditch saws 10 are connected by the fitting pieces 14, there is some free space between the fitting pieces 14 and the insertion holes 13a. Therefore, the drainage ditch saws 10 can be bent with respect to each other in the connecting direction. Therefore, the drainage ditch saws 10 connected to each other can be wound up along the connecting direction.

The engagement projection 14a formed at the tip of the fitting piece 14 has an insertion hole in the engagement portion 13 on the side of another drain groove ditch saw 10 as shown in FIG. Since it is forcibly inserted into 13a, its tip (lower end surface in the drawing in this embodiment) is formed to have a rounded shape. The engaging protrusion 14a is inserted into the insertion hole 13a of the engaging portion 13 and then engaged with the engaging step portion 13b side facing the engaging hole 13a. It is formed so as to project and have a substantially rectangular step.

The thickness of the fitting piece 14 in the present embodiment is, as shown in FIG. 5C, the thickness of the engaging projection 14 a provided on the tip of another fitting for the drain groove ditch saw 10. Since it is necessary to release the engagement with the engagement step portion 13b formed on the engagement portion 13 side, in order to secure a margin for that, it is thinner than the thickness of the insertion hole 13a on the engagement portion 13 side. It is formed so that.

[0025]

[Effect of device]

 As described above, according to the drainage drainboard saw 10 of the present invention, a plurality of rod-shaped main body portions 11 are integrally connected by the connection portion 12 to form a plate-shaped one having a predetermined gap 16. In addition to being integrally molded, the engaging portion 13 and the fitting piece 14 are integrally formed on the outer surface of the rod-shaped main body portion 11 located at both outer ends thereof, so that they can be partially replaced if necessary. It is of course possible to provide a child member for a drainage gutter that can be easily manufactured, can be manufactured at low cost, and can be easily performed in assembling.

Further, since the drainage ditch saw 10 has the fitting pieces 14 formed to be thinner than the thickness of the insertion hole 13a, even if the drainage ditch saws 10 are connected, Since there is some free space between the joint piece 14 and the insertion hole 13a, it is possible to perform winding along the connecting direction of the drainage ditch saws 10, and thereby cleaning is performed. It is easy to clean up and store the time.

Further, in this drainage drainboard saw 10, since each fitting piece 14 is formed thinner than the thickness of the insertion hole 13a, each drainage drainboard saw 10 can be bent with respect to its connecting direction. Therefore, even if it is placed on a drainage ditch that is not perfectly flat, so-called un-landing phenomenon does not occur and it can be placed in a stable state on the drainage ditch. is there.
