  The outer diameter (lateral width) of the inner cage 2 is set to be smaller than the diameter of the hole 102a of the mass plate 102. Therefore, the inner car 2 can be taken in and out through the hole 102a. A large number of holes 2a are formed in the side portion 2b and the bottom portion 2c of the inner cage 2 throughout. The hole 2a captures large dust (such as fallen leaves).

  The outer car 3 is disposed so as to surround the inner car 2 with a gap Sb below the hole 102 a of the mass plate 102, and is fixed to the mass plate 102 using a plurality of suspension tools 5. The outer cage 3 is formed of a resin in a cylindrical shape and has an upper surface opened. A large number of holes 3a are formed in the side portion 3b and the bottom portion 3c of the outer cage 3 throughout. The hole 3a is for catching small dust (such as a cigarette filter) and is formed smaller than the hole 2a of the inner car 2.

  The rainwater filter 1 constructed as described above removes most of the dust from the rainwater R in the same manner as in the prior art. Explaining this, when it rains, as shown in FIG. 2, rainwater R enters the inner car 2 through the hole 13a of the lid 13 and the hole 102a of the mass plate 102 together with dust. Here, large dust A (fallen leaves, etc.) is captured in the hole 2a of the inner cage 2. Subsequently, dust (such as a cigarette filter: not shown) smaller than the hole 2a of the inner car 2 passes through the inner car 2 together with the rainwater R and enters the outer car 3, and is captured by the hole 3a of the outer car 3. The

  The rainwater R from which dust has been removed in this way passes through the outer basket 3 and enters the main body 12, passes through the horizontal filter 15, passes through the drainage port 14, and flows out from the drainage pipe 16. It is discharged to (not shown).

 In the rainwater filter 1 according to the present embodiment, a gap Sa is provided between the cars 2 and 3 and the mass plate 102. The height Sah of both the gaps Sa (see FIG. 1) is the space between the inner car 2 and the outer car 3 due to the rainwater R flowing from the holes 102a of the mass plate 102 when the large dust A overflowing from the upper end of the inner car 2 flows. It is set to a height that allows it to flow out into the water. In the present embodiment, this height is set to 20 mm to 50 mm, for example.

  Therefore, even if large garbage A such as fallen leaves overflows from the upper end of the inner car 2 as shown in FIG. 2, the garbage A is caused to flow out to the space between the inner car 2 and the outer car 3 using this gap Sa. Is possible. For this reason, the holes 102a of the mass plate 102 and the holes 13a of the lid 13 are not clogged immediately, so there is no need to frequently take out and clean the inner car 2. Therefore, the rainwater filter 1 according to the present embodiment can save labor in cleaning the inner basket 2.

  In the rainwater filter 1 according to the present embodiment, a space Sb is provided between the bottoms 2c and 3c of both the cars 2 and 3. For this reason, even if the bottom 2c of the inner basket 2 is clogged with the garbage A, the rain water R that has been stained from the inner basket 2 can be discharged from the bottom 3c of the outer basket 3 through this space Sb. As described above, in the rainwater filter 1 according to the present embodiment, it is possible to discharge the rainwater R from the bottom 3c of the outer cage 3 as compared with the case where the bottoms 2c and 3c of both the cages 2 and 3 are in contact with each other. Therefore, the drainage efficiency of rainwater R can be increased.

  Further, in the rainwater filter 1 according to the present embodiment, the hole 2a of the inner car 2 is formed larger than the hole 3a of the outer car 3, so that the hole 2a of the inner car can be prevented from being clogged with dust immediately. it can. Therefore, the rainwater filter 1 according to the present embodiment can suppress a decrease in the drainage efficiency of the rainwater R.

(Second Embodiment)
FIG. 3 is a schematic diagram showing a state before use of the rainwater filter 6 according to the second embodiment of the present invention. In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and different parts are mainly described. The rainwater filter 6 according to the present embodiment includes a mass plate 102, an inner cage 2, an outer cage 7, a plurality of hanging devices 4 for the inner cage 2, and a plurality of hanging tools 8 for the outer cage 7. It has.

  Both the cages 2 and 7 are formed in a cylindrical shape with resin. The upper end surface of the outer car 7 is set lower than the upper end surface of the inner car 2. Specifically, the upper end surface of the outer cage 7 is formed to be lower in height than the upper end surface of the outer cage 3 (see FIG. 1) of the first embodiment. A large number of holes 7a are formed in the side 7b and the bottom 7c of the outer cage 7 throughout. This hole 7a is the same as the hole 3a of the outer cage 3 of the first embodiment.

  When the upper end surface of the outer car 7 is set lower than the upper end surface of the inner car 2 in this way, the height Sch of the gap Sc between the outer car 7 and the mass plate 102 is set to be smaller than that of the inner car 2 and the mass. It becomes larger than the height Sah of the gap Sa between the plate 102. Therefore, as shown in FIG. 4, even if large garbage A such as fallen leaves overflows from the upper end of the inner car 2, the garbage A is spilled into the space between the inner car 2 and the outer car 7 by the rainwater R. It becomes possible to pour into. Therefore, clogging of the holes 102a of the mass plate 102, clogging of the holes 13a of the lid 13, and clogging of the gaps Sa and Sc itself can be reliably suppressed. Therefore, the rainwater filter 6 according to the present embodiment is further reduced in the frequency of taking out the inner cage 2 as compared with the rainwater filter 1 according to the first embodiment, and further saves labor in cleaning the inner cage 2. it can.

  When the outer car 3 of the first embodiment is used, if the outer car 3 is attached to the mass plate 102 using the hanging tool 8 of the present embodiment, the upper end surface of the outer car 3 is attached to the inner car. 2 lower than the upper end surface.

(Third embodiment)
FIG. 5 is a schematic diagram showing a state before use of the rainwater filter 9 according to the third embodiment of the present invention. In the present embodiment, the same parts as those in the second embodiment are denoted by the same reference numerals, and different parts are mainly described. The rainwater filter 9 according to the present embodiment includes a mass plate 102, an inner car 2, an outer car 7, a plurality of hanger 91 for the inner car 2, and a plurality of hanger 92 for the outer car 7. It has.

  In the present embodiment, the plurality of suspension tools 91 and 92 are configured such that the suspension position of the inner car 2 and the suspension position of the outer car 7 can be adjusted up and down, respectively. This will be specifically described below.

  The hanging tool 91 for the inner car 2 includes two adjustment plates 93, two wires 94, and two fixing tools 96. The two adjustment plates 93 are attached to face the upper part of the side part 2b of the inner car 2. The adjustment plate 93 is provided with a plurality of holes 93a at intervals in the vertical direction. The fixture 96 is attached to the mass plate 102. The fixing device 96 is a screw type and includes a bolt 96a and a nut 96b.

  One end of the wire 94 is locked in the hole 93 a of the adjustment plate 93. The other end of the wire 94 is locked between the bolt 96a and the nut 96b of the fixture 96 through a through hole 102b provided outside the hole 102a of the mass plate 102. Therefore, by changing the position of the hole 93a of the adjustment plate 93 that locks one end of the wire 94, the hanging position of the inner car 2 can be adjusted up and down.

  The hanging device 92 for the outer car 7 includes two adjustment plates 93, two wires 95, and two fixing devices 96. The two adjustment plates 93 are attached to face the upper portion of the side portion 7 b of the outer cage 7.

  One end of the wire 95 is locked in the hole 93 a of the adjustment plate 93. The other end of the wire 95 is locked between the bolt 96a and the nut 96b of the fixture 96. Therefore, by changing the position of the hole 93a of the adjustment plate 93 that locks one end of the wire 95, the hanging position of the outer car 7 can be adjusted up and down.

  In addition, you may comprise the hanging tool of the inner cage | basket 2 from the wire 94 and the fixing tool 96, without using the adjustment plate 93. FIG. In this case, the other end of the wire 94 is locked in the hole 2a of the inner car 2. Similarly, the hanger of the outer car 7 may also be composed of the wire 95 and the fixture 96 without using the adjustment plate 93. In this case, the other end of the wire 95 is locked in the hole 7 a of the outer cage 7. Therefore, by changing the positions of the holes 2a and 7a up and down, the hanging positions of both the cars 2 and 7 can be adjusted up and down, respectively.

  When the hanging positions of the two cars 2 and 7 are adjusted up and down in this way, the heights Sah and Sch of the gaps Sa and Sc between the two cars 2 and 7 and the mass plate 102 are set so as to reduce the amount of dust in the rain. It can be changed freely according to the amount of inflow. For example, when the inflow amount of dust is large, the heights Sah and Sch of the gaps Sa and Sc are set larger than usual.

  Therefore, as shown in FIG. 6, even if large garbage A such as fallen leaves overflows from the upper end of the inner car 2, there is a margin between the garbage A and the hole 102a of the mass plate 102. By this, it becomes possible to easily drain the space between the inner car 2 and the outer car 7 and toward the inside of the main body 12. As a result, clogging of the holes 102a of the mass plate 102, clogging of the holes 13a of the lid 13, and clogging of the gaps Sa and Sc themselves can be more reliably suppressed. Therefore, the rainwater filter 9 according to the present embodiment can reliably save labor for cleaning the inner basket 2 regardless of the amount of inflow of dust.

  The inner car 22 is disposed with a gap Sd below the hole 102 a of the mass plate 102, and is detachably attached to the mass plate 102 using a plurality of hanging tools 4. The inner cage 22 is formed of a resin in a cylindrical shape and has an upper surface opened.

  The outer diameter (lateral width) of the inner cage 22 is set to be smaller than the diameter of the hole 102 a of the mass plate 102. Therefore, the inner car 22 can be taken in and out through the hole 102a. A large number of holes 22a are formed in the side portion 22b and the bottom portion 22c of the inner cage 22 throughout. The hole 22a is the same as the hole 2a of the inner cage 2 in each of the above embodiments. In the present embodiment, the upper end 22d of the inner car 22 is cut obliquely downward from the side of the lid 13 close to the hole 13a.

  Therefore, as shown in FIG. 8, when large garbage A such as fallen leaves overflows from the upper end of the inner car 22, the garbage A is likely to fall, so that the garbage A is placed between the inner car 22 and the outer car 7. It is possible to easily pour out into the space and the main body 12. Therefore, clogging of the hole 102a of the mass plate 102, clogging of the hole 13a of the lid 13, and clogging of the gaps Sd and Sc itself can be reliably suppressed. Therefore, in the rainwater filter 21 of the present embodiment, the labor of cleaning the inner car 22 can be surely saved.

  Further, the upper end of the outer car 7 may be cut obliquely in the same manner as the inner car 22. In this case, it becomes possible to easily drop large garbage A such as fallen leaves in the outer basket 7 into the main body 12, and the outer basket 7 can be prevented from being clogged with the large garbage A, and the drainage efficiency of rainwater. Can be maintained in a high state.

  In the present embodiment, the heights of the inner car 22 and the outer car 7 are fixed. However, the heights of both the cars 22 and 7 using the lifting tools 91 and 92 described in the third embodiment. You may make it change.

(Fifth embodiment)
FIG. 9 is a perspective view of the rainwater filter 31 according to the fifth embodiment of the present invention. Note that in this embodiment, the same portions as those in the above embodiment are denoted by the same reference numerals, and different portions will be mainly described. The rainwater filter 31 according to the present embodiment includes a mass plate 102, an inner car 32, an outer car 33, two hanger 34 for the inner car 32, and four hanger 35 for the outer car 33. It has.

  The inner car 32 is disposed with a gap Sa below the hole 102a of the mass plate 102, and is detachably attached to the mass plate 102 using two suspensions 34.

  The inner car 32 is formed in a cylindrical shape and has an upper surface opened. More specifically, the side portion 32b of the inner cage 32 is formed by rounding a resin net into a cylindrical shape and connecting both ends with strings. The bottom 32c of the inner car 32 is formed of a resin net, as with the side 32b. The bottom portion 32c is attached to the lower end portion of the side portion 32b with a string or the like.

  Accordingly, in the inner car 32, the mesh forming the side portion 32b and the bottom portion 32c forms the hole 32a. This hole 32a captures large dust (such as fallen leaves) in the same manner as the hole in the inner cage described in the above embodiments.

  In addition, holding members 321 are mounted on the upper and lower ends of the side portion 32b. The holding member 321 is formed in a ring shape from a resin, and holds the shape of the inner car 32. Reinforcing members 322 are provided inside the holding members 321 as shown in FIG. The reinforcing member 322 is made of metal and is formed in a ring shape. FIG. 10 shows the upper holding member 321.

  Further, in FIG. 10, a pair of notches 321a and 321a are formed on the upper surface of the holding member 321 so as to face each other. Due to the notches 321a and 321a, a part of the reinforcing member 322 is exposed oppositely. Both ends of the handle 323 are hooked on the exposed portion. The handle 323 is formed in an inverted U shape with metal.

  Moreover, the two hanging tools 34 are each formed in a bowl shape by metal. Each hanging tool 34 is formed of a hook part 34a and a support part 34b. As shown in FIG. 9, the hook 34a is hooked and fixed to the peripheral edge of the hole 102a of the mass plate 102. As shown in FIG. 10, the lower end portion 34 c of the support portion 34 b is fixed to the outer surface of the upper holding member 321 (the outer surface of the inner car 32).

  Further, as shown in FIG. 11, the outer diameter (lateral width) of the inner car 32 is set smaller than the diameter of the hole 102 a of the mass plate 102. Thus, the operator can attach and detach the inner car 32 by holding the handle 323 and taking the inner car 32 out and through the hole 102a. At this time, the suspension members 34 and 34 are formed so that the support portions 34 b and 34 b abut on the inner peripheral surface of the hole 102 a of the mass plate 102. Therefore, the hanger 34, 34 and the hole 102a serve as a guide when the inner car 32 is taken in and out. Therefore, the rainwater filter 31 according to the present embodiment can smoothly take in and out the inner car 32.

  Furthermore, since the shape of the inner car 32 is always held by the holding member 321 and the reinforcing member 322, it is also possible to prevent deformation during taking in and out.

  Next, the outer car 33 will be described. As shown in FIG. 9, the outer car 33 is disposed with a gap Sc below the hole 102 a of the mass plate 102 so as to surround the inner car 32, and is attached to the mass plate 102 by using four suspension tools 35. It is fixed. A space Sb is provided between the bottom 33c of the outer car 33 and the bottom 32c of the inner car 32, as in the above embodiments.

  The outer cage 33 is formed in a cylindrical shape and has an upper surface opened. More specifically, the side portion 33b of the outer cage 33 is formed by rounding a resin net into a cylindrical shape and connecting both ends with strings. The bottom portion 33c of the outer cage 33 is formed of a resin net, similar to the side portion 33b. The bottom portion 33c is attached to the lower end portion of the side portion 33b with a string or the like.

  Therefore, in the outer cage 33, the meshes forming the side portion 33b and the bottom portion 33c form a hole 33a. The hole 33a captures small dust (such as a cigarette filter) similar to the hole of the outer car described in the above embodiments, and is formed smaller than the hole 32a of the inner car 32.

  In addition, holding members 331 are attached to the upper and lower ends of the side portion 33b. The holding member 331 is made of resin and is formed in a ring shape. The holding member 331 holds the shape of the outer car 33. Reinforcing members (not shown) are provided inside the holding members 331, respectively. This reinforcing member is made of metal and is formed in a ring shape.

  As shown in FIG. 12, the upper holding member 331 is formed by two upper and lower resin ring members 332 being stacked one above the other. Four attachment portions 333 are provided on the outer peripheral surface of the upper ring member 332. The four attachment portions 333 are arranged at equal intervals (cross direction) on the outer peripheral surface of the upper ring member 332. Each mounting portion 333 is formed so as to protrude laterally. Each attachment portion 333 is provided with an attachment hole (not shown) penetrating vertically.

  The four hanging tools 35 can adjust the vertical position of the outer car 33. Specifically, as shown in FIG. 9 and FIG. 12, each suspension tool 35 includes a support bar 35a and three nuts 35b.

  The support bar 35a extends vertically through a mounting hole (not shown) provided around the hole 102a of the mass plate 102 and a mounting hole (not shown) of the mounting portion 333 of the holding member 331. Has been. The support bar 35a is threaded.

  One of the three nuts 35b is fixed to the upper surface of the mass plate 102 by screwing into the upper end portion of the support bar 35a from above the mass plate 102 as shown in FIG. The remaining two nuts 35b are screwed to the support bar 35a so as to sandwich the mounting portion 333 as shown in FIG.

  In the four hanging tools 35 configured as described above, when adjusting the vertical position of the outer car 33, the two nuts 35b sandwiching the attachment portion 333 are loosened, and the support bar 35a and the attachment portion 333 are thus removed. Adjust the mounting position with the top and bottom. That is, in the rainwater filter 31 of the present embodiment, the height of the outer car 33 can be easily adjusted in a state where the position of the outer car 33 is lower than the inner car 32. In other words, the height Sch of the gap Sc between the outer car 33 and the mass plate 102 is easily adjusted in a state where it is larger than the height Sah of the gap Sa between the inner car 32 and the mass plate 102. Is possible.

  Therefore, even if the amount of inflow of dust is large, the height Sch of the gap Sc is increased by setting the position of the outer car 33 lower than usual, so that large dust such as fallen leaves overflowing from the upper end of the inner car 32 can be removed. The rainwater can surely flow out into the space between the inner car 32 and the outer car 33 and toward the inside of the main body 12. Therefore, clogging of the holes 102a of the mass plate 102, clogging of the holes 13a of the lid 13, and clogging of the gaps Sa and Sc itself can be reliably suppressed. Therefore, the rainwater filter 31 according to the present embodiment further reduces the frequency of taking out the inner car 32 as compared with the rainwater filter 6 according to the second embodiment, and further saves labor in cleaning the inner car 32. it can.

  In addition to the attachment portion 333 described in this embodiment, an attachment portion 433 as shown in FIG. The attachment portion 433 is made of resin and is fixed to a holding member 431 attached to the upper end portion of the outer car 33. And this attachment part 433 is provided with the attachment part 433a for outer cages, and the attachment part 433b for suspension tools.

  The outer car mounting portion 433a is formed in a U-shape. The outer car mounting portion 433a is disposed so as to sandwich the holding member 431 from the lower side to the left and right. The lifting tool mounting portion 433b is coupled to the upper end of the outer car mounting portion 433a and is disposed so as to be sandwiched from above and below the holding member 431 together with the lifting device mounting portion 433b. Moreover, the attachment part 433b for lifting implements is formed extending from the attachment part 433a for the outer car to the side. An attachment hole (not shown) is provided through the top end of the suspension attachment portion 433b so as to penetrate vertically.
