Description

Technical Field

[0001] The present invention relates to a water channel cover for covering water channels such as agricultural water channels and side ditches with panel materials, and a water channel cover device using the same.

Background Art

[0002] For water channels parallel to roads, measures are taken to prevent bicycles traveling on the road and pedestrians passing on the road from accidentally falling into the water channel, or to prevent children from playing in the water channel. For example, side ditches with relatively narrow and shallow widths are often covered with concrete lids or gratings. In addition, when the width of the water channel is relatively wide, a protective fence is often installed at the boundary between the road and the water channel, or the water channel is often covered with a net or panel material.

[0003] When covering with a covering material such as a net or panel material, it is effective in preventing pedestrians and children from entering the water channel. However, when it is necessary for a manager or the like to enter the water channel, it is difficult to remove the covering material only at a predetermined location, and it is necessary to enter the water channel from the upstream side or the downstream side where the covering material is not covered.

[0004] For example, Patent Document 1 discloses a covering material for a side ditch for covering an upper open portion of a side ditch provided on a side portion of a road. A mesh surface body is used as a covering material main body, and the covering material main body is formed in an arch shape or a mountain shape in which the upper surface side is convex when viewed from the side ditch length direction in a state of covering the upper open portion of the side ditch, and one end of the mesh surface body is rotatably fixed by a hinge. A covering material for a side ditch has been proposed.

Mode for Carrying Out the Invention

[0015] Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

[0016] In the drawings, 10 is a support member, 20 is a shaft member attached to the support member 10, 30 is a panel member disposed between the support members 10, and 40 is a spacer disposed on the opposite side of the panel member 30 with respect to the support member 10.

[0017] FIG. 1 is a plan view showing an embodiment of a water channel cover according to the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is an enlarged cross-sectional view taken along line A-A of FIG. 1, FIG. 4 is an enlarged view of the vicinity of the support member 10 in FIG. 1, FIG. 5 is an enlarged end view taken along line B-B of FIG. 4, FIG. 6 is an enlarged end view taken along line C-C of FIG. 4, FIG. 7 is an enlarged cross-sectional view taken along line D-D of FIG. 4, and FIG. 8 is an enlarged cross-sectional view taken along line E-E of FIG. 2. The support members 10 are arranged in a pair on the left and right at intervals in the flow direction of the water channel W. As shown in FIG. 3, they have a bottom plate portion 11 installed between the side walls S, S of the water channel W and a vertical plate portion 12 standing upright upward from the bottom plate portion 11. Here, the left-right direction of the water channel cover 100 is the length direction of the water channel W, the front-back direction is the width direction of the water channel W and is the direction from one side wall S to the other side wall S, and the up-down direction is the depth direction of the water channel W. Hereinafter, the description will be made in this way.

[0018] A connecting member 13 is installed between the left and right support members 10. As shown in FIGS. 1 and 3, in this embodiment, the connecting member 13 is a square pipe material with a rectangular cross-section. One end in the longitudinal direction is fixed to the bottom plate portion 11 of one support member 10, and the other end is fixed to the bottom plate portion 11 of the other support member 10. In this embodiment, two are attached at intervals in the front-back direction. Thereby, the left and right support members 10, 10 are connected via the connecting member 13. In this embodiment, further, an intermediate member 14 is arranged in the left-right intermediate portion between the support members 10, 10 in the front-back direction, is installed between the side walls S, S, and is fixed to the two connecting members 13, 13.

[0019] Two position adjusting members 15 are attached to the bottom plate portion 11 at intervals in the front-back direction. As shown in FIGS. 3 and 6, the position adjusting member 15 is fixed to the upper surface of the bottom plate portion 11 and has an extending portion 15a whose one end side extends toward the bottom surface of the water channel W. The extending portion 15a can be attached to a position where it abuts against or is close to the side wall S in accordance with the width dimension of the water channel W. Thereby, the movement of the support member 10 in the front-back direction can be restricted regardless of the width of the water channel W.

[0020] The support member 10 has a shaft member 20 protruding toward the other support member 10. As shown in FIGS. 3 and 7, the shaft members 20 are cylindrical and are arranged in two in the front-rear direction with the opening direction being the left-right direction.

[0021] The panel member 30 is disposed between a pair of left and right support members 10, 10 to cover the upper opening of the water channel W so that pedestrians such as pedestrians and children cannot easily enter the water channel W. In this embodiment, the panel member 30 is a mesh panel in which the vertical members 31 and the horizontal members 32 are arranged in a lattice pattern, and in addition to the above-described intrusion prevention effect, the inside of the water channel W can be visually recognized from the outside of the water channel W.

[0022] The panel member 30 has body edges 33, 33 at both front and rear ends. The body edge 33 is cylindrical and a hollow portion 34 is formed along the left-right direction. In this embodiment, as shown in FIG. 7, both front and rear ends of the vertical member 31 are bent in an arc shape to form the body edge 33. The shaft member 20 of the support member 10 is inserted into the body edge 33.

[0023] As a result, the panel member 30 is fixed to the upper part of the opening of the water channel W, and pedestrians cannot easily enter the water channel W.

[0024] In the support member 10, a spacer 40 is disposed on the side opposite to the panel member 30. As shown in FIGS. 1 and 5, the spacer 40 is formed in a reverse U-shaped cross section including a top plate portion 41 formed in the front-rear direction and side plate portions 42 hanging down from both left and right ends of the top plate portion 41, and is installed between the side walls S, S.

[0025] Next, the relationship between the support member 10 and the shaft member 20 will be described. As shown in FIG. 4, the support member 10 and the shaft member 20 are fastened via a bolt member 51. In this embodiment, the shaft member 20 has a bottom, and the bottom portion 21 has an internal thread portion 21a penetrating in the left-right direction which is the thickness direction, and the vertical plate portion 12 of the support member 10 has a through hole 12a at a position corresponding to the internal thread portion 21a.

[0026] Since the shaft member 20 is inserted into the body edge 33 of the panel material 30, for example, if the bolt member 51 fastening the front shaft member 20 is removed, the shaft member 20 will come off from the vertical plate portion 12 of the support member 10 and the fixed state of the front body edge 33 will be released. As shown by the arrow in Fig. 3, the panel material 30 can be rotated about the rear shaft member 20. Thereby, the administrator can enter the water channel W through the upper opening of the opened water channel W by lifting the front side of the panel material 30.

[0027] The head 53 of the bolt member 51 is disposed between the left and right side plate portions 42 of the spacer 40. As shown in Fig. 8, the side plate portion 42 of the spacer 40 has a notch portion 42a cut out from the lower end at a position corresponding to the female screw portion 21a. Since the front and rear ends of the spacer 40 are open, it is possible to operate the head 53 with a jig through the opening.

[0028] Thereby, when the administrator needs to enter the water channel W or when the panel material 30 is damaged and needs to be replaced, the bolt member 51 can be removed to open and close the panel material 30 or remove the panel material 30. Since the head 53 of the bolt member 51 is difficult to be visually recognized by passers-by who are outsiders and it is not easy to remove the bolt member 51, it is possible to prevent passers-by from opening, closing or removing the panel material 30. Although it is preferable that the head 53 is covered by the top plate portion 41 of the spacer 40, this makes it difficult to operate the bolt member 51. Therefore, in this embodiment, the front and rear end portions of the top plate portion 41 are notched so that a part of the head 53 of the bolt member 51 can be visually recognized in plan view.

[0029] FIG. 9 is a plan view showing an embodiment of a water channel cover device according to the present invention, and FIG. 10 is an enlarged end view taken along line F-F of FIG. 9. In a water channel W, a water channel cover device 200 is arranged in which water channel covers 100 sharing a spacer 40 are continuously arranged on the left and right with the spacer 40 arranged between panel members 30 fixed between left and right support members 10. Specifically, in adjacent support members 10 sandwiching the spacer 40, a bolt member 54 that passes through left and right side plate portions 42, 42 of the spacer 40 from a vertical plate portion 12 of one support member 10 and penetrates the vertical plate portion 12 of the other support member 10, and a nut member 55 screwed onto the bolt member 54 can connect the support members 10 to each other.

[0030] Thereby, an administrator can install the water channel cover device 200 according to the required length at a required location of the water channel W to suppress a passerby from entering the water channel W, and can open, close, or remove the panel member 30 at an arbitrary location of the water channel cover device 200.

[0031] As an example of a method for assembling the water channel cover device 200, a panel member 30 is attached between left and right support members 10 and installed in the water channel W, and the spacer 40 is arranged adjacent to the support member 10. Since the side plate portion 42 of the spacer 40 has a notch portion 42a as shown in FIG. 8, the spacer 40 can be arranged side by side with the support member 10 without interfering with the head portion 53 of the bolt member 51 protruding laterally from the vertical plate portion 12 in order to fix the shaft member 20. Thereby, after temporarily arranging the support member 10, the panel member 30, and the spacer 40, the connecting operation using the bolt member 54 described above can be performed, resulting in excellent workability.

[0032] As described above, the water channel cover 100 of the present embodiment is a water channel cover 100 that covers the upper opening of the water channel W, and includes a pair of left and right support members 10 installed at intervals in the water channel W, a shaft member 20 attached to both support members 10 at intervals in the front-rear direction and protruding toward the other support member 10, and a panel member 30 disposed between the support members 10 and covering the upper opening. The support member 10 has a spacer 40 having a top plate portion 41 and a side plate portion 42 on the side opposite to the panel member 30. The shaft member 20 is fixed to a bolt member 51 that penetrates the support member 10 from the side plate portion 42 of the spacer 40. The panel member 30 has body edges 33 at both front and rear ends, and the front and rear body edges 33 are respectively fitted to the shaft member 20.

[0033] Accordingly, when the administrator needs to enter the water channel W or when the panel member 30 is damaged and needs to be replaced, the administrator can operate and remove the bolt member 51 from the front-rear direction opening of the spacer 40 to open and close the panel member 30 or remove the panel member 30. In addition, since the bolt member 51 is difficult to be visually recognized by passersby, it is possible to prevent the panel member 30 from being opened and people from easily entering the water channel W.

[0034] Although not shown, as the form of the panel member 30, for example, a transparent resin plate may be used, or a form in which a large number of through holes are formed in the thickness direction of an opaque plate material may be used. In short, as long as the inside of the water channel W can be visually recognized and passersby and the like cannot easily enter the water channel W.

[0035] Figs. 11 to 13 are explanatory views showing a second embodiment of the water channel cover according to the present invention. Fig. 11 is a plan view, Fig. 12 is an enlarged cross-sectional view taken along line G-G of Fig. 11, and Fig. 13 is an enlarged view of the vicinity of the auxiliary shaft member of Fig. 12. Compared with the water channel cover 100 shown in Figs. 1 to 10, the water channel cover 300 according to the present embodiment is mainly different in the arrangement of the panel member 30 and the form of the support member 10. Therefore, the description will be centered on the differences from the water channel cover 100 shown in Figs. 1 to 10, and the same reference numerals will be given to the same components as those already described, and the description thereof will be omitted.

[0036] The left and right support members 10 each have an auxiliary support column 16 standing upright from the middle part in the front-rear direction thereof, and an upper plate portion 17 in the form of a vertical plate formed in the front-rear direction at the upper end of the auxiliary support column 16, and are formed in a substantially E shape in side view. And the upper plate portion 17 is provided with auxiliary shaft members 60 which are mounted at intervals in the front-rear direction and project toward the other upper plate portion 17. A connecting member 13 is installed between the left and right upper plate portions 17.

[0037] The support member 10 has front and rear shaft members 20 and two auxiliary shaft members 60 above the middle part in the front-rear direction. The front shaft member 20 and the auxiliary shaft member 60 on the front side of the support member 10 are fitted with two front and rear body edges 33, 33 of one panel material 30, and the auxiliary shaft member 60 and the shaft member 20 on the rear side of the support member 10 are fitted with two front and rear body edges 33, 33 of the other panel material 30. The two panel materials 30 are arranged in a mountain shape in side view.

[0038] Thereby, as shown by the arrow in FIG. 12, when the administrator removes the bolt member 51 fastening the front shaft member 20, one panel material 30 can be rotated about the front auxiliary shaft member 60. The other panel material 30 on the rear side can also be rotated in the same manner. Therefore, since only one of the front and rear panel materials 30, 30 can be opened and closed, compared with the water channel cover 100 shown in FIG. 1, the load of the opening and closing operation of the panel material 30 is reduced.

[0039] FIG. 14 is a plan view showing an embodiment of a water channel cover device 200 using the water channel cover 300. Similar to the water channel cover 100 shown in FIG. 7, by arranging a spacer 40 between the panel materials 30 fixed between the left and right support members 10 in the water channel W, a water channel cover device 200 in which the water channel covers 300 are continuously arranged in the left-right direction can be formed.

[0040] In addition, in FIG. 13, a part of the water channel cover 300 may be replaced with the water channel cover 100 to form a water channel cover device 200 using the water channel covers 100 and 300 in combination.

[0041] As described above, the water channel cover 300 of the present embodiment is a water channel cover 300 that covers the upper opening of the water channel W, and includes a pair of left and right support members 10 installed at intervals from the water channel W, and a panel member 30 disposed between the support members 10 and covering the upper opening. The support member 10 includes a shaft member 20 and an auxiliary shaft member 60 that are installed at intervals in the front-rear direction and project toward the other support member 10. A spacer 40 having a top plate portion 41 and a side plate portion 42 is disposed on the side opposite to the panel member 30 of the support member 10. The shaft member 20 is fastened to the support member 10 by a bolt member 51 that penetrates the support member 10 from the side plate portion 42 of the spacer 40. The panel member 30 includes body edges 33 disposed at intervals in the front-rear direction, and the front and rear body edges 33 are fitted to the shaft member 20 and the auxiliary shaft member 60.

[0042] Accordingly, when the administrator needs to enter the water channel W, if the bolt member 51 is removed from the front-rear opening of the spacer 40, the shaft member 20 will be disengaged from the support member 10, so that the panel member 30 can be opened and closed with the auxiliary shaft member 60 as the axis. On the other hand, since it is not easy for passers-by to visually recognize inside the opening of the spacer 40, it is not easy to remove the bolt member 51, and it is possible to prevent passers-by from easily entering the water channel W.

[0043] Further, in the water channel cover 300 of the present embodiment, the support member 10 has a shaft member 20 attached to the front and rear, and two auxiliary shaft members 60 are attached between the shaft members 20. The front and rear body edges 33 of one panel member 30 are fitted to the shaft member 20 and the auxiliary shaft member 60 on the front side of the support member 10, and the body edges 33 of the other panel member 30 are respectively fitted to the shaft member 20 and the auxiliary shaft member 60 on the rear side of the support member 10.

[0044] Accordingly, it becomes possible to open and close only one of the front and rear panel members 30, 30, so there is no need to open and close the panel member 30 in the front-rear direction, and the load of the opening and closing operation of the panel member 30 is reduced.

[0045] As described above, the fence of the present invention has been explained based on the embodiments. However, the present invention is not limited to these embodiments. Various modifications conceived by those skilled in the art without departing from the gist of the present invention are also included within the scope of the present invention.
