Description

The present invention relates to a partition cover for a hole formed through a rainwater catch basin cover (including a manhole cover).

Patent Documents 1 and 2 describe a hole partition cover for preventing mosquitoes from entering and exiting through a plurality of holes formed in the lid of the rainwater catch basin, which serves as a drainage port and a handle opening, when the rainwater catch basin becomes a puddle in which mosquitoes breed. It is

However, in the case lid through-hole cover disclosed in Patent Document 1, only two components, the cover main body (metal mesh) (11) and its reinforcing plate (metal plate) (31), are sufficient. Even if there is an advantage, in the process before bending and hemming the reinforcing plate (metal plate) (31), the cage portion (13) and the collar portion (15) of the cover body (metal mesh) (11) must be removed. ) must be drawn, which increases the number of processes, resulting in high manufacturing costs.

The reinforcing plate (metal plate) (31) of the cover body (metal mesh) (11) has a donut shape in plan view, and both the cage reinforcing portion (33) and the flange reinforcing portion (35) are Since it has an arcuate surface, wrinkles occur on the arcuate surface when the former bending process and the latter hemming process are performed, making it difficult to process beautifully, and also inferior in safety during handling.

In addition, the size and shape of the hole that opens into the rainwater trough lid (the trough lid through-hole) varies depending on the manufacturer and material of the trough lid. The basket-shaped part (13) is U-shaped (semicircular) when viewed from either the longitudinal direction or the width direction (lateral direction). Since they are draw-formed so as to fit in with almost the same size (size) and shape, a wide variety of covers are available according to the size (size) and shape of the hole (through hole) (5) of the lid. Therefore, it is not possible to expect versatility or mass production effect.

On the other hand, in the "lid cover" disclosed in the above Patent Document 2, locking portions (33) formed by bending a single metal plate into V-shapes facing each other are connected to a handle hole (a hole in the lid) (13a). Even if there is an advantage that it can be attached to the opening edge of the handle hole (hole) (13a) in the lid (masu lid) (13) due to the elasticity generated when it is pushed in, the locking part (33) can be attached to its horizontal part (33a). ) at the center of the cover main body (metal plate) (32) by rivet (36), welding, adhesion, etc., and when connecting via the rivet (36), In order to prevent relative rotation between the engaging portion (metal plate) (33) and the cover main body (metal plate) (32), a detent portion (35) is formed by spot welding or the like around the rivet (36). They must be installed in a scattered distribution, resulting in high manufacturing costs.

Furthermore, since the cover main body (metal plate) (32) is made of so-called punching metal having a large number of through holes (32d) scatteredly distributed, the horizontal portion (33a) of the locking portion (metal plate) (33) ), the weight is unnecessarily increased, and it is difficult to distribute the openings of the through holes (32d) as a group of fine meshes such as a wire mesh. There is also a problem that the function as a mouth deteriorates.

The purpose of the present invention is to completely solve such problems. a metal cover body plate having

Consisting of two members, a mesh that can drain water but prevents mosquitoes from entering and a flat wire mesh that has the same rectangular planar shape as the cover body plate,

The above cover body plate is

a top plate surface having a rectangular or elliptical drainage hole punched out in the center of the top plate surface, which serves as a flange that engages the opening edge of the lid hole from above and communicates with the lid hole;

Only the central portion that is folded back from the peripheral edge of the top plate surface to the back side so as to sandwich the corresponding peripheral edge of the wire mesh and that occupies a certain length of parallel long sides at the peripheral edge of the top plate surface a left and right pair of backing support surfaces for the wire net, each continuously extending inward from the tip of the folded back sandwiching the peripheral edge of the wire net;

Both backing support surfaces are bent downward at a substantially right angle from the inwardly extending tip portions, and the bent portion of the fixed depth is used as a bent portion to project outward in opposite directions. A pair of left and right elastic insertion leg pieces shaped like a shape,

When both insertion leg pieces of the cover main body plate are inserted into the cover hole from above so as to be freely inserted and removed, the restoration expansion force caused by the inward contraction and deformation of the both insertion leg pieces presses against the inner wall surface of the cover hole or closes the cover hole. It is characterized in that it is determined to be locked to the lower edge of the opening.

Moreover, in claim 2, both of the cover body plate and the wire mesh are made of stainless steel material.

In claim 3, the distance between the right and left sides of the insertion leg pieces of the cover main body plate facing each other at the lower ends is set to a narrow dimension equal to or less than the width of the opening of the lid hole,

Similarly, the distance between the right and left sides of the insertion leg pieces facing each other at the dogleg-shaped bent portion is set to be wider than the width of the opening of the lid hole.

In claim 4, the top plate surface of the cover body plate is formed with a rectangular bending ridge line for bending each of the insertion leg pieces downward at a substantially right angle from the extended ends of the backing supporting surfaces of the cover body plate for the wire mesh. Alternatively, it is characterized by extending a certain length in the front-rear direction in parallel at positions corresponding to both straight long sides of the drainage port punched and formed as an ellipse.

In claim 5, the fixed length extending in the front-rear direction of both insertion leg pieces of the cover body plate is set to be shorter than the opening length of the cover hole,

It is characterized in that the corner positions of the bottom ends of both the insertion leg pieces and the front and rear ends are each shaped as a circular arc surface.

Further, in claim 6, the contour shape of the drain hole punched and formed in the center of the top plate surface of the cover body plate has an elliptical shape as the body and a plurality of notches provided at the elliptical opening edge. It is characterized by displaying an overall appearance of a turtle with concave grooves on its head, tail and four legs.

According to the configuration of claim 1, unlike the "case lid through hole cover" of Patent Document 1 mentioned at the beginning, the wire mesh is flat, so the peripheral edge of the top plate surface of the metal cover main body plate is attached to the peripheral edge. Hemming may be performed so as to sandwich the metal mesh, and there is no need to draw the cage-shaped portion and collar portion of the wire net prior to the hemming.

In addition, since a metal plate cover main body (so-called punching metal) having a large number of scattered through holes like the "lid cover" of Patent Document 2 is not adopted, rivet caulking is required in addition to the hemming process described above. , welding, bonding, etc., there is no need to connect and integrate the engaging portion of a separate metal plate, and the lid hole partition cover can be easily manufactured, which is remarkably excellent in mass production efficiency.

In that case, the metal cover body plate has a rectangular planar top plate surface, and the peripheral edges (4 sides) of the top plate surface are folded back to form the same rectangular flat metal mesh peripheral edges (4 sides). Since the top plate is sandwiched between two sides, there is no possibility that the top plate surface will be wrinkled due to the hemming process, and a good trimmed state can be obtained.

In addition, a pair of left and right backing support surfaces for the wire net continue to extend inward from the tip of the folded back to the back side where the peripheral edge of the wire net is sandwiched on the top plate surface. Since the wire netting is supported from the back side (lower side) by the contact support surface, the cover body plate and the wire netting can be kept in a stable and firm assembly state, and the illegal deformation of the wire netting and the top plate surface are prevented. There is no risk of separation from

If the configuration of claim 2 is adopted, both the cover body plate and the wire mesh are less likely to rust, which helps to improve the durability.

In particular, if the structure of claim 3 is adopted, the cover main body plate can be easily and smoothly inserted into the lid hole from the lower ends of the elastic insertion leg pieces, and the inside of the lid hole can be easily and smoothly inserted. In the process of entering, the bending portions of the two insertion leg pieces facing each other in a dogleg shape naturally shrink and deform inward, and the restoring expansion force associated with the deformation elastically crimps the inner wall surface of the lid hole or the lid. Since it is engaged with the lower edge of the opening of the hole, the lid hole partition cover can be stably attached without rattling and floating, and both insertion leg pieces can be manually removed from the lid hole.

If the configuration of claim 4 is adopted, the bending ridgeline for bending the two elastic insertion leg pieces downward at substantially a right angle is a straight (elliptical or rectangular) drain hole stamped on the surface of the top plate. Since the top plate of the cover main body plate is located at a position corresponding to both straight long sides and extends in parallel for a certain length in the front-rear direction, the top plate is supported by both backing support surfaces of the cover body plate against the wire mesh. There is no possibility that the drainage port on the surface will be narrowly restricted, and the drainage performance of the lid hole can be maintained normally.

Also, if the configuration of claim 5 is adopted, both insertion leg pieces of the cover main body plate can always be easily and reliably inserted into the inside of the cover hole, and furthermore, the lower tip and front and rear ends of both insertion leg pieces can be easily and reliably inserted into the lid hole. Since the corner positions of both ends are formed as circular arc surfaces, there is no danger of injuring fingers during insertion work into the lid hole or other handling.

Furthermore, if the configuration of claim 6 is adopted, the wire mesh that is in a state of partitioning the drainage hole punched and formed on the top plate surface of the cover body plate from the back side (lower side) may imply a tortoise shell. Together, based on the longevity symbol of the turtle, the durability of the product-lid hole partition cover can be impressed.

FIG. 4 is a plan view of the lid hole partition cover; FIG. 3 is a front view of FIG. 2; FIG. 3 is a side view of FIG. 2; 3 is a bottom view of FIG. 2; FIG. 3 is a cross-sectional view taken along line 6-6 of FIG. 2; FIG. 3 is a cross-sectional view taken along line 7-7 of FIG. 2; FIG. FIG. 4 is a front cross-sectional view showing the beginning of insertion of the lid hole partition cover into the rainwater catch basin lid. It is a front cross-sectional view similarly showing the state of use in which the insertion of the lid hole partition cover is completed.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is a plan view of a rainwater basin lid (M) to which the lid hole partition cover (A) of the embodiment is applied. A plurality of holes (10) are formed therethrough which function as handle openings for operation.

The cover hole (10) is generally rectangular or elliptical (oval) in plan view, and the length (Y) of the opening is 50 to 70 mm, and the width (X) is 19 to 70 mm. 26 mm. The rainwater catch lid (M) shown in the figure is a disk-shaped concrete product, but its planar shape is also square, and its material is not limited to concrete products, but also metal products and synthetic resin products.

The lid hole partition cover (A) according to the embodiment of the present invention comprises a metal cover body plate (B) having a rectangular planar shape larger than the lid hole (10) of the rainwater catch lid (M), and a From two members, a fine mesh (for example, 1 mm) that prevents mosquitoes from entering (passing through) and a flat wire mesh (11) having a rectangular planar shape with the same size as the cover body plate (B), FIGS. It is equipped with a structure that is assembled and integrated as follows.

That is, the metal cover body plate (B) of the lid hole partition cover (A) is preferably made of a stainless steel plate having a certain thickness (for example, 0.2 mm to 1.0 mm) or another rust-proof metal plate, It has a rectangular top plate surface (12) that serves as a flange that can be engaged with the opening edge of the lid hole (10) from above. Moreover, an elliptical or rectangular drainage port (13) communicating with the lid hole (10) is punched (cut out) in the center of the top plate surface (12).

In that case, in the illustrated example, the drainage port (13) is punched into an elliptical shape having substantially the same opening width (W) as the cover hole (10), and at the same time, the punched elliptical opening peripheral edge is formed. A pair of front and rear notch grooves (14) and (15) and a pair of front and rear notch grooves (16) and (17) symmetrical to each other are also punched out in a communicating open state, and the drain port (13 ) has an elliptical shape as the body, a large arc-shaped notch groove (14) on the front side as the head, and a V-shaped notch groove (15) on the rear side as the tail. It is designed to suggest the overall appearance of a turtle with four small arcuate grooves (16) and (17).

Since the turtle is a symbol of longevity and an auspicious creature, the appearance of its figure and shape can impress the excellent durability and unique design of the product-lid hole partition cover (A).

The peripheral edge of the rectangular top plate surface (12) of the cover body plate (B) is folded back to the back side (lower side) by hemming so as to sandwich (wrap) the peripheral edge of the wire mesh (11) located correspondingly. ing. As the wire mesh (11), it is preferable to employ a stainless steel wire mesh that does not rust.

Moreover, of the four sides (periphery) bordering the top plate surface (12), the parallel long sides (both left and right sides) (12y) occupy a constant length (L) (45 mm in the example shown). Only the central part, as shown in FIGS. extended in the direction

Furthermore, the inwardly extended tips of both backing support surfaces (18) for the wire mesh (11) are drain holes (cutouts) formed by punching (cutting out) oval or rectangular shapes in the top plate surface (12). 13) at positions substantially corresponding to both long sides (13y) of 13), and then bent downward at a substantially right angle (θ) to form a pair of left and right elastic insertion leg pieces (19). It is in a state of being confronted as

(O--O) are bending ridges for bending the two elastic insertion leg pieces (19) from the inwardly extending ends of the two backing support surfaces (18), respectively, downward at substantially right angles (θ). , and extends in parallel in the front-rear direction for the same constant length (L) as the parallel long sides (both left and right sides) (12y) forming the central portion of the top plate surface (12).

In other words, both elastic insertion leg pieces (19) of the cover body plate (B) have a rectangular shape extending in the front-rear direction by the constant length (L) as shown in FIGS. In order to ensure safety in handling, the corner positions of the lower tip of the long side and the front and rear ends of both short sides are each shaped as an arc surface (20). The downward bent constant depth (Z) of the two elastic insertion legs (19) is, for example, 20-25 mm.

In addition, both elastic insertion leg pieces (19) having a constant depth (Z) are stretched outward in opposite directions, with the middle portion thereof as a bending portion (P) parallel to the bending ridge line (OO). The left and right mutual distance (D1) facing each other at the lower tip is a narrow dimension equal to or less than the opening width (X) of the lid hole (10) (for example, 25 mm). , so that it can be used by inserting it into the lid hole (10) easily and smoothly.

Similarly, the distance (D2) between the left and right sides of the bending portion (P) of both elastic insertion legs (19) facing each other is wider than the opening width (X) of the lid hole (10). With a size (for example, 30 mm), when both leg pieces (19) are inserted into the lid hole (10), the bent portion (P) in the dogleg shape is forcibly contracted and deformed, and the expansion force tries to restore it. It is set to be elastically crimped to the inner wall surface of the lid hole (10).

The lid hole partition cover (A) according to the embodiment of the present invention has the above-described configuration. The top plate surface (12) of the cover main body plate (B) is worked by applying the lower ends of both elastic insertion leg pieces (19) in FIG. 8 to the opening edge of the cover hole (10) By pressing downward with the fingers of a person or an appropriate tool and inserting both elastic insertion leg pieces (19), a dogleg-shaped bent portion (P) protruding from the middle portion of both leg pieces (19) is inserted. As shown in FIG. 9, it is elastically crimped to the inner wall surface of the lid hole (10) or elastically locked to the lower edge of the opening of the lid hole (10) by its restoring expansion force. will do. As a result, there is no risk of natural, unintentional loose movement, and a stable fixed state is maintained.

During use in such an attached state, rainwater flows into the rainwater basin through the drain port (13) of the cover body plate (B). A certain wire net (11) is provided with a mesh through which mosquitoes cannot enter (pass through), so there is no risk of mosquitoes entering or exiting through the wire net (11).

When removing the lid hole partition cover (A) from the lid hole (10), insert a screwdriver into the mutual gap between the top plate surface (12) of the cover body plate (B) and the trough lid (M). By inserting a spatula or other suitable tool and applying a so-called lever action, both elastic insertion leg pieces (19) are once lifted from the cover hole (10), and then the top plate surface (12) is lifted. Grab it and pull it out.

It should be noted that the strength of the repulsive force of both elastic insertion leg pieces (19) should be adjusted in advance according to the bending angle of the dogleg-shaped bent portion (P) of both leg pieces (19) and the degree of outward projection. can be done.
