Description

  The present invention relates to a garbage-removing cover for dredging that can prevent the inflow of dirt into the basket while ensuring a sufficient amount of rainwater drainage, and a mounting structure therefor.

  Conventionally, trash such as fallen leaves has come to the eaves of a house, is dropped by rainwater, is transported to the vicinity of the mouth or inside the tub, and is accumulated by humus, etc., which causes clogging of trash and drainage of rainwater There was a problem of inhibiting.

  In order to solve these problems, a dust-removing member 100 for preventing clogging of dust as shown in FIG. 11 is attached to the outlet of the eaves. This dust-removing member 100 is provided with a flange portion 102 on the outer periphery of the male cylindrical body portion 101, four frames 103 are erected from the flange portion, and a circular opening 104 is provided at the upper end. Is. The dust-removing member 100 is attached to the dropping port by dropping the male cylindrical portion 101 and screwing it into a female cylindrical portion (not shown) below the opening. (Patent Document 1)

  Since the dust-removing member 100 is firmly attached by being screwed into the female cylindrical portion below the drop opening, there is no fear of being blown away by a typhoon or the like, but there are the following problems.

  In other words, the dust removing member 100 must be able to be rotated inside the eaves when screwed into the female cylindrical portion on the lower side of the drop opening, so that it is limited to a small structure. Specifically, a small dust-removing member having a diameter of about 60 mm, a height of about 35 mm, and a distance between the frames 103 and 103 of about 30 mm is often used. For this reason, when the entire dust-removing member is covered with dust such as fallen leaves, the flow path is blocked, making it difficult to drain, and rainwater overflows from the eaves in heavy rain.

  Further, if the mutual distance between the frames 103 is reduced in order to prevent the inflow of dust into the basket, the opening area of the dust removal member 100 is further reduced and a sufficient amount of drainage cannot be secured. Therefore, there is a problem in that a considerable amount of dust passes through the dust-removing member 100 and flows into the bag, causing clogging of the dust. Such a dust removal member 100 through which dust easily passes is a siphon-type rainwater drainage device proposed by the present applicant, that is, a siphon tube (竪) having a small diameter is connected to a spout of a spear. It is unsuitable for a device that drains a large amount of rainwater due to the siphon action of the kite. If the dust-removing member 100 is attached to the outlet of this device, the thin kite will immediately clog the dust, and the rainwater There was a problem of overflowing from.

  Further, when dust becomes clogged and needs to be cleaned, there is also a problem that the dust removal member 100 described above is complicated to remove and to attach it to the outlet in a watertight manner.

  On the other hand, a fallen leaf prevention eaves auxiliary material 200 as shown in FIG. 12 is also used. The auxiliary material 200 for fallen leaf prevention eaves has a substantially U-shaped cross section and is mounted inside the eaves with the U-shaped opening facing down. A comb-like stopper 202 having a water mouth 201 and extending toward the bottom of the eaves is formed at the end in the longitudinal direction (see Patent Document 2). Although this fallen leaf prevention eaves auxiliary material 200 has the advantage of being lightweight and easy to remove, it has the following problems.

In other words, since the fallen leaf prevention eaves auxiliary material 200 is mounted so as to cover the eaves, if the water inlet 201 becomes clogged with garbage, it becomes difficult for rainwater to flow into the eaves, thereby serving as an eaves. There was a problem that it could not be fulfilled. In addition, the auxiliary material 200 is unstable to be attached to the eaves and there is a concern that the auxiliary material 200 may be blown away by a strong wind if the dimensions do not match the eaves.

  The present invention has been made in view of the above circumstances, and while ensuring a sufficient amount of drainage of rainwater, it prevents the inflow of dust into the cage, enhances detachability, and reduces labor such as construction and dust cleaning. An object of the present invention is to provide a versatile bag dust-removing cover that can be securely attached and reduced and a mounting structure for the same.

In order to solve the above-mentioned problems, the garbage-removing cover for garbage according to the present invention is a dust-removing cover that covers the mouth of the garbage, and its four circumferential surfaces and upper surface are formed in a lattice shape that can prevent the passage of garbage. In addition, the lower lattice of the lattice-like four circumferential surfaces is divided by auxiliary bars, and the lower surface of the dust-removing cover is opened and has an opening area larger than the dropping port. To do.

In gutter waste except cover of the present invention, more preferred if the vertical bars of case child-like four circumferential surfaces protrude outward from the middle of the lateral beam. Further, it is also preferable that the grid-like four-sided auxiliary rail protrudes outward from the intermediate horizontal rail. Particularly 60～300Cm ² is the total open area of the grid-like four circumferential surfaces, the total open area of the grid-like upper surface 20～60Cm ^2, lattice-shaped waste except cover spaces between the vertical bars of the four circumferential surface is 5~15mm is Highly preferred.

  Further, according to the attachment structure of the garbage dust cover of the present invention, the above-mentioned garbage dust cover is put on the lid of the fence to cover the mouth, and the cover presser having the locking portions at both ends is removed from the garbage. It is placed on the cover, the locking portions at both ends are locked to the ears of the bag, and the bag dust-removing cover is pressed and fixed to the bottom surface of the bag with a cover pressing tool.

  In the mounting structure of the present invention, the cover presser is formed with a water passage opening corresponding to the lattice on the lattice-shaped upper surface of the garbage dust-removing cover, and the cover retainer so that the water passage overlaps with the lattice on the upper surface. Is preferably placed on the garbage-removing cover for dredging, and an engagement piece is projected downward from the edge of the water passage opening of the cover presser, and two adjacent adjoining lattice-shaped upper surfaces of the dust-removing cover for dredging More preferably, the mounting structure is such that the engaging piece is engaged with the crosspiece.

  Another attachment structure of the present invention is to cover the drop cover by covering the cover for dust with the above dust cover, and to the engaging claw provided around the drop opening of the dust cover. The horizontal crosspiece at the lower end is engaged from below, the engaging claw is positioned between the vertical crosspieces on the four circumferential surfaces, and the garbage dust-removing cover is fixed to the eaves.

The dust removal cover for garbage of the present invention is formed in a lattice shape whose four circumferential surfaces and upper surface can prevent the passage of dust, and since its lower surface is opened and has an opening area larger than the mouth of the garbage, this dust removal cover. When the cover is attached so as to completely cover the mouth of the eaves (eaves), it is possible to prevent dust such as fallen leaves from dropping into the stiffener from the mouth by the lattice-like four peripheral surfaces and the upper surface. The dust-removing cover with a large lower end opening attached so as to cover the drop opening is much larger than the conventional dust-removing member that is screwed together so that the lattice-shaped four-surface or upper-surface lattice All eyes are not blocked by dust, and even if some grids are blocked by dust, a sufficient amount of drainage can be secured through other grids. In addition, the large dust drain cover such as the dust cover of the present invention can prevent the inflow of dust into the rigid body by reducing the lattice, and in particular, it has a large amount of waste water and waste to the rigid body. It is ideal as a dust protection cover for siphon-type rainwater drainage systems, where inflow of water becomes a fatal problem. Moreover, since the lattice at the lower part of the lattice-like four-circumferential surface is divided by the auxiliary bars, it is possible to more reliably prevent the inflow of dust while ensuring a sufficient amount of rainwater drainage during heavy rain.

  In addition, a grid-like four-sided vertical rail that protrudes outward from the middle horizontal rail has a gap between the protruding vertical rail, the horizontal rail, and the dust even when the four-circular surface is covered with dust. As a result, rainwater flows in from the gap, so that drainage can be secured. Similarly, the drainage of rainwater can be ensured also by a grid-like auxiliary rail having four circumferential surfaces protruding outward from the intermediate horizontal rail.

In addition, the dust-removing cover in which the total opening area of the lattice-like four-circumference surface is 60 to 300 cm ² , the total opening area of the upper surface is 20 to 60 cm ² , and the distance between the vertical bars is about 5 to 15 mm, Since it is much larger than the dust-removing member, it is possible to drain a large amount of rain water even if it rains, and more reliably prevent the inflow of dust into the basket. Moreover, since the dust-removing cover of the above size can be attached to various eaves used at present, the versatility is high and the cost can be kept low.

  On the other hand, the attachment structure of the garbage dust cover of the present invention does not need to be screwed and attached as in the conventional dust removal member, and the locking parts at both ends are locked to the ears of the basket (eaves). The dust removal cover can be easily attached simply by pressing and fixing the dust removal cover to the bottom surface with the cover presser, and the dust can be easily removed by unlocking the locking parts at both ends and removing the cover presser. You can remove the cover and clean the bag from the mouth. Therefore, the time required for the removal and removal of the dust cover and the cleaning of the bag is reduced and the labor is reduced. Since the hook part is used as the hooked part, and the hooking parts at both ends of the cover presser are locked to this ear part, it is not necessary to newly provide the hooked part in the bag, and the existing ear part can be used. By utilizing this, the locking portions at both ends of the cover presser can be easily and reliably locked, and there is no fear that the locking portions will come off from the ears naturally.

  Further, in the above mounting structure, the cover presser is provided with a water passage corresponding to the lattice on the lattice-shaped upper surface of the garbage dust-removing cover, and the cover retainer so that the water passage overlaps with the lattice on the upper surface. Since the rainwater can flow from the water inlet of the cover retainer through the grid on the top surface of the dust remover cover, the cover retainer is stacked on the upper surface of the dust remover cover. However, the amount of drainage will not decrease.

  Furthermore, an engagement piece protrudes downward from the edge of the water passage opening of the cover presser, and the above engagement piece is engaged with two adjacent bars on the lattice-like upper surface of the garbage dust cover. The mounting structure prevents the dust cover and the cover presser from being displaced relative to each other by the engagement of the engagement piece and the two crosspieces. This can be further improved.

  In addition, another mounting structure of the present invention can be mounted with one touch by simply putting the dust cover on the lid of the bag and pressing it down. Since it engages with the engaging claws provided in the surroundings from below, the dust removal cover does not come off upward, and the engagement claws are located between the vertical bars of the dust removal cover. Even when the dust cover is about to move, the engaging claw engages with the vertical beam and the movement is prevented. Therefore, even if a large amount of rainwater flows in the cage, there is no fear that the dust cover will be washed away.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a garbage dust cover according to an embodiment of the present invention, FIG. 2 is a schematic front view showing an installation structure of the garbage dust cover of the present invention, and FIG. 3 is a perspective view of the attachment structure. FIG. 4 is a cross-sectional view of the mounting structure, FIG. 5 is a perspective view of a cover presser used in the mounting structure, and FIG. 6 is a perspective view showing the cover presser placed on the dust-removing cover of the mounting structure. .

  A bag dust-removing cover 1 (hereinafter simply referred to as a cover 1) shown in FIG. 1 is integrally formed in a trapezoidal shape with a thermoplastic synthetic resin, and its planar shape is an oval shape. The four circumferential surfaces of the cover 1 are formed in a lattice shape by a large number of vertical bars 2 and three oval-shaped horizontal bars 3 and have a lattice size 4 that can prevent passage of dust such as fallen leaves. Are lined up in two rows. In addition, the oval upper surface of the cover 1 is also formed in a lattice shape with the crosspieces 5 in the longitudinal direction and a plurality of crosspieces 6 in the width direction, and lattices 7 having a size capable of preventing the passage of dust such as fallen leaves. It is arranged in two rows in the width direction. Note that four or more horizontal bars 3 on the four circumferential surfaces may be formed, and two or more bars 5 in the longitudinal direction of the upper surface may be formed.

  As shown in FIGS. 1 and 4, the oval lower surface of the cover 1 is opened to the whole, and the lower surface opening 8 has an opening area much larger than the opening 9 a of the eaves 9. ing. For this reason, when the cover 1 is put on the drop opening 9a of the flange 9, the drop opening 9a is surrounded by the cover 1 and completely covered.

  It is preferable that the interval between the vertical beam 2 and the vertical beam 2 on the lattice-shaped four-circumferential surface is set to about 5 to 15 mm. When the interval is larger than 15 mm, dust such as fallen leaves easily flows into the cover 1 together with rainwater. Conversely, when the interval is smaller than 5 mm, the lattice 4 on the four-circumference surface is reduced and the total opening area of the four-circumference surface is reduced. For this reason, the inflow of rainwater into the cover 1 is reduced, resulting in inconvenience that the drainage performance is lowered. Furthermore, the mutual space | interval of the vertical crosspiece 2 is 10-13 mm, and is set to the most preferable space | interval of 12 mm in this embodiment.

The size (length, width, height) of the cover 1 is not particularly limited as long as it is a size that can be accommodated in a general-purpose type eaves (eave eaves) 9, but the total opening area of the four circumferential surfaces is 60 to 300 cm. It is preferable to set to about ^2, and it is preferable to set the total opening area of the upper surface to about 20 to 60 cm ² . If the total opening area of the four peripheral surfaces and the upper surface is less than the above range, the amount of rainwater flowing into the cover 1 (in other words, the amount of drainage from the outlet 9a) is greatly reduced, and the drainage is insufficient during heavy rain. On the contrary, even if the total opening area of the four circumferential surfaces and the upper surface exceeds the above range, further improvement in drainage performance corresponding to that cannot be expected, and the cover 1 is simply enlarged. It is. Therefore, the height, length and width of the cover 1, the number and thickness of the vertical bars 2, the distance between the vertical bars 2, the thickness and distance of the horizontal bars 3, and the upper surface of the four circumferential surfaces and the upper surface are within the above-mentioned range. It is preferable to appropriately determine the number, thickness, and interval of the crosspieces 5 in the longitudinal direction and the number, thickness, and interval of the crosspieces 6 in the width direction.

  When the cover 1 is mounted on the drop opening 9a of the reed 9 as shown in FIG. 4, only rainwater and minute dust flowing through the reed 9 flow into the cover 1 and pass through the reed 12 from the drop 9a. Large dust such as fallen leaves is prevented from passing by the lattice-shaped four peripheral surfaces and the upper surface of the cover 1, so that the clogging of the basket 12 can be prevented. In addition, the cover 1 is much larger than the conventional dust-removing member that is screwed and attached, and the entire opening area of the lattice-shaped four-circumferential surface and the upper surface is large as described above, and all the lattices are dusty. Since there is no concern about being blocked by trash, even if some of the grids are blocked by dust, a large amount of rainwater flows into the cover 1 through the other grids to ensure a sufficient amount of drainage. be able to.

  As shown in FIGS. 2, 3, and 4, the attachment structure of the garbage dust-removing cover according to the present invention covers the above-described cover 1 on the dropping opening 9 a of the eaves 9 so as to surround the dropping opening 9 a. The cover 1 is completely covered and the cover 1 is pressed and fixed to the bottom surface 9b of the flange 9 with a cover presser 10 made of synthetic resin.

  As shown in FIG. 5, the cover presser 10 rises upward from the center horizontal presser plate 10a, left and right inclined plates 10b and 10c protruding obliquely upward from both sides thereof, and the tips of these inclined plates. End covers 10d and 10e are provided. At both ends of the cover presser 10, that is, at the upper ends of the end plates 10d and 10e, concave locking portions 10f and L-shaped locking portions 10g are provided. Is formed. The central holding plate 10a is formed with three water inlets 10h corresponding to the grids 7 on the upper surface of the cover 1 (water outlets having a size corresponding to the two grids 7 and 7 arranged on the left and right). Engagement pieces 10i and 10i are provided so as to project downward from both ends of the edge of each water passage 10h. The number of water passages 10h may be two or less or four or more, and the size of the water passages 10h may be a size corresponding to each lattice 7 on the upper surface of the cover 1.

  When such a cover presser 10 is placed on the upper surface of the cover 1, as shown in FIG. 6, the water passage openings 10 h of the cover presser 10 overlap with the lattices 7, 7 on the upper surface of the cover 1. Since the engagement pieces 10i and 10i are fitted into the lattices 7 and 7 and engage with the two adjacent bars 6 and 6 on the upper surface of the cover 1, the relative displacement between the cover 1 and the cover pressing tool 10 is increased. Can be prevented.

  In the mounting structure shown in FIGS. 2 to 4, the cover presser 10 is placed on the cover 1 that covers the drop opening 9 a of the flange 9, and the relative relationship between the cover 1 and the cover presser 10 is as described above. In addition to preventing misalignment, the hooks 9f, 10d projecting inwardly from the upper ends of both side walls of the flange 9 are used as locked parts, and the locking parts 10f, 10g at both ends of the cover presser 10 are used as the ears 9c, 9d. The cover 1 is fixedly attached to the bottom surface 9b of the flange 9 with a pressing plate 10a at the center of the cover pressing tool 10 and attached thereto. When the cover 1 is attached with the cover presser 10 in this way, the inclined plates 10b and 10c of the cover presser 10 serve as spring plates, and the cover 1 is strongly pressed by the presser plate 10a. Combined with the fact that the relative displacement from 10 is prevented by the engaging piece 10i, the cover 1 can be reliably fixed.

  Locked portions for locking the lock portions 10f and 10g at both ends of the cover 1 may be newly formed on the inner surfaces of both side walls of the flange 9, but the ear portions 9c and 9d are formed as in this embodiment. If it is used as a locked portion, it is not necessary to form new locked portions on the inner surfaces of both side walls of the flange 9, and the locking portions 10f and 10g at both ends of the cover presser can be locked easily and reliably. This is preferable.

  With the fixing structure as described above, it is not necessary to screw and attach the dust-removing member as in the prior art, and both ends of the cover presser 10 placed on the cover 9 with the cover 1 placed on the drop opening 9a. By simply locking the locking portions 10f and 10g to the ear portions 9c and 9d of the flange 9, the cover 1 can be easily and surely pressed and fixed to the bottom surface 9b of the flange 9 without being displaced. And if the latching parts 10f and 10g with respect to the ear | edge parts 9c and 9d are cancelled | released and the cover presser 10 is removed, the cover 1 can be removed easily and the scissors 12 can be cleaned from the drop opening 9a. it can. Accordingly, the time required for the work of detaching the cover 1 and the cleaning of the bag 12 is shortened and the labor is reduced, so that the maintenance becomes easy. Further, even if the cover presser 10 is stacked on the upper surface of the cover 1, rainwater can flow from the water inlet 10 h of the cover presser 10 through the lattice 7 on the upper surface of the cover 1, so that the amount of drainage does not decrease.

  In some cases, a conventional dust-removing member may be dropped and attached to the opening 9a, and the cover 1 may be put on the lid 9a and pressed and fixed with the cover presser 10. In this way, dust can be prevented from entering. There is an advantage that can be seriously blocked.

  FIG. 7 is a perspective view of a garbage dust cover according to another embodiment of the present invention.

  In this cover 1, vertical bars 2a on the four circumferential surfaces protrude outwardly from the intermediate horizontal bars 3 in a bow shape. Since the other configuration is the same as that of the cover 1 of FIG. 1 described above, the same reference numerals are given to the same portions in FIG.

  Such a cover 1 has a gap between the protruding vertical beam 2a, the horizontal beam 3 and the garbage even when the four peripheral surfaces are covered with dust such as fallen leaves, and rainwater flows from this gap. There is an advantage that can be secured.

  FIG. 8 is a perspective view of a garbage dust cover according to still another embodiment of the present invention.

  In this cover 1, each lattice 4 at the lower part of the four-circumferential surface is divided into left and right by a vertical auxiliary rail 2b, and the auxiliary rail 2b protrudes outwardly from the middle horizontal rail 3 in a bow shape. In addition, you may form the auxiliary crosspiece 2b sideways and the lattice 4 may be divided into 2 parts up and down. Since the other structure of this cover 1 is the same as that of the cover 1 of FIG. 1 mentioned above, the same code | symbol is attached | subjected to the same part in FIG. 8, and description is abbreviate | omitted.

  Such a cover 1 can more reliably prevent intrusion of dust by the lattice 4 divided into two by the auxiliary beam 2b while ensuring a sufficient amount of drainage of rainwater during heavy rain, and moreover, the auxiliary beam 2b. Because of the protrusion, even if the lower part of the lattice-like four-sided surface is covered with dust such as fallen leaves, rainwater flows in through the gaps created between the protruding auxiliary rail 2b, horizontal rail 3, vertical rail 2, and garbage There is an advantage that drainage can be secured.

  FIG. 9 is a cross-sectional view showing a structure for attaching a dust trash cover according to still another embodiment of the present invention, and FIG. 10 is a perspective view showing a spear opening portion with the dust proof cover removed.

  As shown in FIGS. 9 and 10, this attachment structure covers the drop opening 9 a by covering the drop-off dust cover 1 with the drop dust cover 1, and the engaging claws provided around the drop opening 9 a. 11 is engaged with the horizontal beam 3a at the lower end of the dust removal cover 1 from below, and the engagement claw 11 is positioned between the vertical beams 2 of the dust removal cover 1.

  A total of four engaging claws 11 are formed on each of two sides (two sides parallel to both side walls of the flange 9) of the rectangular flange portion 9e at the upper end of the drop opening 9a. The engaging claws 11 have a right triangle shape, and are formed to face each other so that the inclined surfaces 11a are outside. The distance between the upper ends of the inclined surfaces 11a, 11a of the opposing engaging claws 11, 11 is the same as or slightly narrower than the distance between the left and right horizontal rails 3a, 3a at the lower end of the dust protection cover 1. The distance between the lower ends of 11 a and 11 a is wider than the distance between the left and right horizontal rails 3 a and 3 a of the dust removal cover 1. Each of the engaging claws 11 is formed so as to protrude outward from the square flange portion 9e by a half, and the gap between the protruding engaging claws 11 and the bottom surface 9b of the flange 9, that is, the rectangular flange portion 9e. The horizontal rail 3a at the lower end of the dust removal cover 1 is fitted into a gap corresponding to the thickness t.

  In this mounting structure, the left and right horizontal rails 3a and 3a at the lower end of the dust-removing cover 1 are attached by pressing the dust-removing cover 1 over the drop opening 9a in which the engaging claws 11 are formed as described above. When it is lowered while expanding outward along the inclined surfaces 11a, 11a of the opposing engaging claws 11, 11, it passes over the engaging claws 11, 11 and reaches the bottom surface 9b of the flange 9, when The crosspieces 3a and 3a are elastically restored to the original state, the horizontal crosspieces 3a and 3a are fitted into the gaps between the engaging claws 11 and 11 and the bottom surface 9b of the flange 9, and the horizontal crosspieces 3a and 3a are engaged with the claws from below. 11 and 11, and the engaging claws 11 and 11 are positioned between the vertical bars 2 of the dust removal cover 1, and the dust removal cover 1 is attached.

  With such a mounting structure, the dust removal cover 1 can be attached with one touch by simply covering the drop opening 9a of the basket 9 with a single touch, and the dust removal cover covered on the drop opening 9a of the bowl 9 Since the left and right horizontal rails 3a, 3a at the lower end of 1 are engaged with the engaging claws 11, 11 facing each other from below, there is no fear that the dust removal cover 1 will come off and the vertical rails of the dust removal cover 1 Since the engaging claws 11 and 11 are positioned between the two, even if the dust-removing cover 1 is about to move, the engaging claws 11 and 11 are engaged with the vertical rail 2 to prevent the movement. Therefore, even if a large amount of rainwater flows through the basket 9, it can be securely attached so that the dust cover 1 does not come off and flow away.

  As mentioned above, although the typical embodiment was mentioned and the garbage dust cover of the present invention and its attachment structure were explained, the present invention is not limited only to these embodiments, for example, protruded in the above-mentioned bow shape.
