The shape, diameter and drilling pitch of the group of nozzles 11e can be variously set within a range that can achieve the purpose of removing fallen leaves and the like clogged in the rain gutter. Will be described in the section of a method of removing fallen leaves and the like clogged in the rain gutter.

The tap water supply pipe 12 is formed, for example, as a cylindrical pipe member, and substantially coincides with the cylindrical vertical gutter 1 on the back surface (outer peripheral surface facing the house side) of the cylindrical vertical gutter 1. It is provided in an integrated state. Then, as described above, the upper end 12a of the tap water supply pipe 12 substantially communicates integrally with the communication opening 11d of the nozzle member 11, and further, as shown in FIG. A large-diameter fitting hole 12c for mounting the metal fitting 13 is formed.

As shown in FIG. 6, the hose connection fitting 13 is formed, for example, as a cylindrical pipe member (preferably a flexible pipe), and the upper end thereof is fitted with the tap water supply pipe 12. It has a fitting portion 13a formed in an outer shape that can be fitted tightly with the mating hole 12c, and further has a lower end, one end of which is attached to a household water tap (not shown). And a hose attaching / detaching portion 13b for detachably attaching the other end of the water guide hose. As the flexible water guide hose, an appropriate commercially available product (not shown) such as a rubber hose or a vinyl hose is used.

Connection method) and tap water supply pipe 1 for cylindrical downspout 1
As for the integration means (or fixing method) 2 and the like, known integration means such as integral molding, welding, welding, and adhesion are used.

[0038] Hereinafter, thus the case where the gutter of the configured illustrated embodiment is provided on the first floor of the roof R ₁ in the representative example, a method for removing such fallen leaves clogged in the gutter. First, the first floor and roof R ₁ of eaves gutter of the left and right that are arranged along the edge line 3, 3 ', for example, faucet cylindrical installed in an appropriate location of the house external wall W near (not shown) The downspout 1 is connected with the funnel 2 to assemble the rain gutter shown in the figure.

In this case, as for the assembling method or assembling procedure of each unitized member, a known assembling method or assembling procedure of a rain gutter is used. Then, in this state, the flat leaf dropping net 4 is attached to a predetermined position in the funnel 2, but in the illustrated example, it is attached by the following procedure or procedure.

(A) First, the flat leaf dropping net 4 is held in a substantially vertical position by holding one of the handles 4c of the flat leaf dropping net 4 in the state shown in FIG.
The flat leaf dropping net 4 is inserted into the funnel 2 from the space between the upper opening 2a of the funnel 2 and the left and right eaves gutters 3, 3 '.

(B) At this time, in the insertion process, the lower end of the flat fallen leaf net 4 is inserted into, for example, the lower space of the left eaves gutter 3 while tilting the fallen leaf fall prevention net 4. The end is placed on the net mounting base 2f formed on the left inclined side wall 2d.

(C) Then, while utilizing the flexibility of the frame 4a and the wire netting 4b of the flat leaf dropping net 4, the upper end is bent while the flat leaf dropping net 4 is bent. While passing through the space between the eaves gutters 3 and 3 '.

(D) Thereafter, the flat fallen leaf drop net 4 is stretched to the original plane posture, and one end is placed on the net mounting base 2f 'formed on the right inclined side wall 2d'. Further, the pair of grips 4c are erected so as to be in a state shown by a two-dot chain line in FIG. 2, FIG. 4, and FIG.

As a result, the flat leaf dropping net 4 is held in the funnel 2 by the net mounting bases 2f, 2f 'of the left and right inclined side walls 2d, 2d'. Since the handle 4c is locked to the lower surface of each of the ends 3 and 3 ', a large upward movement of the flat leaf dropping net 4 is suppressed. On the other hand, left and right eaves gutter 3, 3 '
Left and right curved leaf fall nets 5 for the upper open area of
The attachment of 5 'is performed, for example, according to the following procedure or procedure.

For example, a folded portion having an appropriate shape is formed in advance at both lower end edges of each of the curved falling leaf nets 5, 5 '. The lower edges of the curved leaf drop nets 5, 5 'are expanded by utilizing the elasticity of the curved leaf leaf nets 5, 5', and in this state, the lower edges of the curved leaf drop nets 5, 5 'are opened. The eaves gutters 3 and 3 'are attached to the left and right eaves gutters 3 and 3' so as to sandwich the upper edges of the eaves gutters 3 and 3 '. As a result, the curved falling leaf nets 5, 5 'are separated from each other by the frictional force caused by the elastic return force of each net 5, 5'.
It will be semi-fixed to the upper edge of 3 '.

Another example of the mounting method is as follows.
Left and right eaves gutters 3 and 3 'and left and right curved fallen leaf nets 5,
For example, a click stop mechanism or a spring fixing type semi-fixing mechanism, which is widely used for various mechanical devices, is provided between 5 ′ and 5 ′ so that these mechanisms can be detachably semi-fixed. I do. In this manner, when the flat leaf dropping net 4 and the left and right curved leaf dropping nets 5, 5 'are attached, the rain gutter of the illustrated example is completed.

When the flat fallen leaf net 4 is removed from the funnel 2 and the left and right curved leaf fall nets 5,
When the 5 'is removed from the left and right eaves gutters 3 and 3', they are removed by the reverse of the above-described procedures. Now, it is assumed that dead leaves from surrounding trees fall on the rain gutter in such a state.

In this case, the fallen leaves facing the eaves gutter 3, 3 '
It will fall on the curved leaf fall nets 5, 5 'covering the upper open areas of the eaves gutters 3, 3', for example, 4 to 5 mm.
Fallen leaves larger than the mesh size of the corners are temporarily deposited on the curved fallen leaf removing nets 5 and 5 ', but the fallen leaves are blown off when the wind blows, so that the appearance of the house is impaired. It doesn't matter.

However, in the case of fallen leaves smaller than the mesh size such as conifers, for example, a curved fallen leaf removing net 5,
It will enter the eaves gutter 3, 3 'through the mesh of 5'. On the other hand, the leaves falling toward the funnel 2 enter the funnel 2 from the upper opening 2a as they are, regardless of their size, and accumulate on the flat leaf dropping net 4, or leave the mesh of the flat leaf dropping net 4 as it is. Thus, it falls into the cylindrical downspout 1.

[0050] Then, when there is rain when it is in this state, the first floor of the rainwater on the roof R ₁ is taken together with the dust "mushy" and the eaves gutters 3, 3 of the left and right become a rain water ' To the funnel 2 → the cylindrical downspout 1 to the ground G.

At this time, the small leaves falling into the eaves gutters 3 and 3 'flow in the eaves gutters 3 and 3' together with the rainwater which has become "sloppy", and the left and right eaves gutter insertion openings 2e, 2
From the e ', it flows down into the funnel 2 and accumulates on the flat fallen leaf net 4 to block the rain gutter in the funnel 2.

Therefore, when such a phenomenon occurs, one end of a commercially available flexible water-conducting hose is connected to a faucet for domestic water supply, and the other end is connected to a hose attaching / detaching portion of a hose connection fitting 13. 13b and open the faucet stopper. In this case, it is desirable to fasten the outer periphery of the water guide hose with a tightening band.

With this operation, the tap water from the faucet flows into the tap water supply pipe 12 through the water supply hose and the hose connection fitting 13, and the communication opening 11 is formed by the water pressure of the tap water.
d, the nozzle member 11 rises to the position of the nozzle member 11, and further, gushes out from the group of nozzles 11 e of the nozzle member 11 toward the upper opening 2 a of the funnel 2 (in the direction of the arrow in FIGS. 1 and 2). . As a result, the tap water spouted vigorously blows out the fallen leaves and the like deposited on the flat leaf fall prevention net 4 from the upper opening 2a of the funnel 2 to the outside due to the spout pressure. This will eliminate the state of fallen leaves.

Therefore, it is desirable to set the direction of the nozzles 11e of the nozzle member 11 with respect to the upper opening 2a of the funnel 2 in such a direction that such a blowing action can be performed efficiently.

Also, in the case of this tap water blowing action, it is also conceivable that the flat leaf dropping net 4 rises upward from the net mounting bases 2f, 2f 'of the funnel 2 due to the jetting pressure.

However, in the present embodiment, the flat leaf drop guard is held until the grips 4c provided on both sides of the flat leaf fall net 4 come into contact with (engage) the lower ends of the eaves gutters 3, 3 '. The net 4 may float, but will not rise any further. In addition, a known detachable fixing mechanism is provided in advance on the side of the net mounting bases 2f, 2f ', and the flat leaf removing net 4 is moved to the net mounting bases 2f, 2f, 2
It may be configured to be fixed to f ′.

For example, as an example of a detachable fixing mechanism, for example, a simple hook fitting or latch is provided on the net mounting bases 2f, 2f ', and the hook fitting or latch is attached to, for example, a flat fallen leaf removing net 4. A mechanism that hooks on the frame 4a or the wire net 4b can be considered. By the way, the explanation so far has been that the eaves gutters 3 and 3 'on the first floor and the ground G and the eaves gutters 3 and 3' on the second floor and the ground G are all connected via the funnel 2. This is an example of a case in which they are directly connected by a dedicated cylindrical downspout 1.

However, in the case of rain gutters relating to the eaves gutters 3 and 3 'on the second floor, rainwater from the eaves gutters 3 and 3' on the second floor (53 in FIGS. Flow down to the eaves gutters 3 and 3 'on the floor (51 in FIGS. 14 and 15),
Thereafter, there is a case where the water is caused to flow down to the ground G using the cylindrical downspout 1 for the first floor. In such a case, for example, the configuration is as follows.

One example is the eaves gutter 3 on the second floor.
Forcible removal means 10 for exclusive use of fallen leaves such as fallen leaves dedicated to the second floor, to the cylindrical downspout 1 dedicated to the second floor for flowing down from the 3 ′ to the veranda 57 and the eaves gutters 3 and 3 ′ on the first floor via the funnel 2 dedicated to the second floor. And the hose attaching / detaching portion 13 of the forcibly removing means 10 for falling leaves and the like.
b, a water supply hose from a water tap (not shown) provided on the second floor is connected, and tap water from the water tap on the second floor is supplied to the second floor.
It is guided to the nozzle member 11 of the means for forcibly removing fallen leaves and the like dedicated to the floor, and is spouted from the nozzles (11e group).
The structure is such that the fallen leaves and the like accumulated on the flat plate-shaped fallen leaf net 4 are blown out from the upper opening 2a of the funnel 2 on the second floor by the jet pressure of the tap water.

As another example, as shown in FIG. 7, a connecting curved gutter 26 having, for example, a shape as shown in the figure is provided at the lower end of a cylindrical vertical gutter 21 dedicated to the second floor. The lower end of the gutter 26 is located on an eaves gutter (for example, 3 ') dedicated to the first floor.

Then, after being configured in such a state, 2
Tap water supply pipe 32 of means 30 for removing fallen leaves etc. exclusively for floors
The back of the cylindrical downspout 1 for the first floor (surface facing the house side)
Along with the tap water supply pipe 12 dedicated to the first floor, for example, integrally with the cylindrical downspout 1, and the tap water supply pipe 32 dedicated to the second floor is connected to the cylindrical vertical pipe for the first floor. 1 from the back of gutter 1
