Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a gutter joint used for connecting gutters such as eaves gutters and guttering.

(Prior art) In a conventional gutter joint, a water stop rubber 03 is provided on the gutter connection surface 02 at both ends of the joint body 01 in the gutter connection direction, and the surface of this water stop rubber 03 has a water stop rubber 03 as shown in FIG. A plurality of protrusions 04, 04, 04 were provided in a direction orthogonal to the gutter connection direction, and these protrusions 04, 04, 04 were all formed at the same height.

(Problem to be solved by the invention) When connecting a gutter to a gutter joint, generally the gutter is connected so that the axial direction of the gutter matches the connection direction of the gutter joint. In some cases, the gutter is in a disadvantageous condition for performing detailed connection work, and during use, the gutter may sag due to changes in temperature, or may sag under the load of snow accumulation, etc., and it is difficult to maintain this condition. The axial direction of the gutter joint is often misaligned with respect to the connection direction of the gutter joint.

By the way, in such a conventional gutter joint, since the protrusions 04 of the water stop rubber 03 are all formed at the same height, the connection direction of the gutter joint and the gutter 0
When the axial direction of the protrusion 04 is aligned with the axial direction of the protrusion 04
Although all of the ridges are in close contact with the gutter 05 and exhibit sufficient water-stopping function, if the connection direction of the gutter joint and the axial direction of the gutter 05 are misaligned vertically or horizontally, the protrusion 0
The adhesion between Gutter 4 and Gutter 05 was drastically reduced, causing water leakage. Further, even when the connecting direction of the gutter joint and the axial direction of the gutter 05 match, excessive pressure may deform the protrusions of the water stop rubber at the corners of the gutter joint, creating a gap. In the best case, as shown in FIG. 10, the gutter 05 only maintains close contact with the single protrusion 04 disposed at the end.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problems. A joint main body is formed with the vertically installed side wall part, and a water stop rubber is provided on the gutter connection surface at both ends of the joint main body in the gutter connection direction, and a water stop rubber is provided on the surface of the water stop rubber in a direction perpendicular to the gutter connection direction. In a gutter joint in which a plurality of protrusions are provided in a direction, the protrusions are formed at stepwise different heights.

(Function) Therefore, first, when connecting a gutter to the gutter joint of the present invention, the connecting direction of the gutter joint and the axial direction of the gutter must be aligned so that the gutter is in close contact with all the protrusions of the water-stop rubber. and connect. In this way, the fact that the gutter and all of the protrusions formed at stepwise different heights are in close contact with each other means that the higher the protrusion, the stronger the force with which the protrusion is pressed down by the gutter. It is in a state of decline.

Next, if the axial direction of the gutter and the connecting direction of the gutter joint are misaligned, or if the gutter bends during use due to temperature changes or due to load from snow accumulation, etc. , the protrusion that had been pushed down rises up and follows the distance between the gutter and the gutter joint.

In this way, the protrusions of the water stop rubber follow the distance from the gutter, and strive to maintain close contact between the gutter joint and the gutter.

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

First, the configuration of the first embodiment shown in FIGS. 1 to 5 will be explained.

As shown in Fig. 1, the gutter joint A of this embodiment has the following features:
A straight joint that connects the eaves gutter B in a straight line,
It consists of a joint body 10 made of synthetic resin such as hard vinyl chloride resin or ABS resin, and a water stop rubber 20 made of rubber.

The joint body 10 is formed of a bottom portion 11 and side wall portions 12, 12 erected on both side edges of the bottom portion 11,
At the upper ends of the side walls 12, 12, ear receivers 13, 13 that fit into the ears of the eaves gutter B are formed over the entire length in the connection direction. In addition, this joint body 10
is the inner surface of both ends in the gutter connection direction (gutter connection surface) 14,
14 is connected to a gutter B such as an eaves gutter.

As shown in FIG.
4, and three protrusions 21, 22, 23 are provided in parallel on the surface thereof in a direction orthogonal to the gutter connection direction. These protrusions 21, 2
2 and 23 have two different heights, with the central protrusion 22 being higher than the other protrusions 21 and 23. In the following description, the front protrusion 21, the middle protrusion 22, and the inner protrusion 23 will be referred to.

Next, the operation of the first embodiment will be explained.

When connecting a gutter B such as an eaves gutter to the gutter joint A, as shown in FIG.
Insert the end of gutter B so that it is in close contact with both 2 and 23, aligning the connection direction of gutter joint A with the axial direction of gutter B. The state in which the gutter B and the protrusions 21, 22, 23 are in close contact is the state in which the protrusions 21, 22, 23 are pressed by the gutter B, but the protrusions 22 inside are in contact with other Since it is formed higher than the protrusions 21 and 23, it is in a more crushed state as it falls down in the insertion direction.

Incidentally, even if the protrusion 22 is bent and deformed at the corner portion and a gap is created between the protrusion 22 and the gutter B, the protrusion 21 and 23 are in close contact with each other, so that this can be covered.

Next, if the axial direction of gutter B is connected with a slight deviation from the connection direction of gutter joint A, or if during use, gutter B may bend due to temperature changes or be subjected to loads due to snow accumulation, etc. Let me explain what happens when the product bends.

First, as shown in FIG. 4, when the end of the gutter B is lifted up using the protrusion 21 as a fulcrum,
The inner protrusion 22 rises as much as the gutter is separated. That is, even if the gutter B is separated from the inner protrusion 23, it remains in close contact with the inner protrusion 22 and the front protrusion 21.

Furthermore, as shown in FIG.
The inner protrusion 22 rises as much as the gutter is separated. That is, even if the gutter B is separated from the protrusion 21 at the front, it remains in close contact with the inner protrusion 22 and the inner protrusion 23.

In this way, when the gutter B is connected to the gutter joint A, it is in close contact with at least two of the three protrusions 21, 22, 23 formed on the water stop rubber 20. is retained. Moreover, since these protrusions are provided in a direction perpendicular to the gutter connection direction, water leakage can be reliably prevented.

Next, a second example will be described.

In describing the second embodiment, the same components as those in the first embodiment are given the same reference numerals and their explanations will be omitted.

As shown in FIG. 6, this gutter joint consists of three protrusions 31, 32,
33, the front protrusion 31 and the rear protrusion 33 are formed higher than the inner protrusion 32.

Therefore, when connecting gutter B to gutter joint A,
As shown in FIG. 7, when the front protrusion 31 and the back protrusion 33 are pushed down and brought into close contact with all the protrusions 31, 32, and 33, as shown in FIG. When the end lifts up using the protrusion 31 at the front as a fulcrum, the protrusion 33 at the back rises, so that the gutter B remains in close contact with the protrusion 31 at the front and the protrusion 33 at the back. However, as shown in FIG. 9, when the end of the gutter B is pushed down using the protrusion 33 at the back as a fulcrum, the protrusion 31 at the front rises, so that the end of the gutter B
Similarly, the state of close contact with the front protrusion 31 and the rear protrusion 33 is maintained.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes, etc. that do not depart from the gist of the present invention are included in the present invention. It can be done.

For example, in the embodiment, the water stop rubbers provided at both ends of the joint body were both provided on the inner surface of the joint body. and the other on the outer surface. Note that, as a matter of course, both may be provided on the outer surface of the joint body. In any case, the gutter will be connected tightly to the water stop rubber.

In addition, in the example, the application was applied to a straight joint that connects eaves gutters in a straight line, but it is also applicable to curved joints that connect eaves gutters in an L-shape, angle joints that connect eaves gutters and eaves gutters, and water-stop joints. It may also be applied to other gutter joints, such as joints with drain pipes (water collectors).

Further, in the embodiment, the number of protrusions of the water-stop rubber is three, but four or more protrusions may be formed. Also, the height may be formed into three levels: high, medium, and low.
Alternatively, each protrusion may be made different for each protrusion, and may be formed in even smaller stages.

(Effect of the idea) As explained above, when it comes to the gutter joint of the present invention, the end of the connected gutter lifts up and down and deviates from the connection direction of the gutter joint. Even if this happens, the protrusions of the water stop rubber can accommodate the deviation, so at least the minimum level of adhesion between the gutter and the water stop rubber can be ensured. That is, the effect of being able to prevent water leakage is obtained.
