Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vertical gutter connector used to connect an eaves gutter and a vertical gutter.

[Conventional technology]

As shown in FIG. 5, the conventional vertical gutter connector includes an insert member 50 which is formed by providing a flange 52 at the upper end of a cylindrical body 51 that is fitted into a hole 101 formed in a bottom wall 102 of an eaves gutter 100. and a receiving member 60 having a flange 62 provided at the upper end of a cylindrical body 61 externally fitted to the cylindrical body 51 of the insert member 50,
Each cylindrical body 51, 61 of the insertion member 50 and the receiving member 60
They are screwed together via threads, whereby both members 50 and 60 are temporarily fixed to the eaves gutter 100. Then, they waited for the adhesive previously applied to the flanges 52, 62 of both members to dry.

Such a conventional vertical gutter connector is suitable for connecting the vertical gutter 110 to the wide eaves gutter 100.
That is, in the case of a wide eave gutter 100, it is possible to use a vertical gutter connector having a relatively large-diameter insertion member 50 depending on the width of the eaves gutter 100, so that the permissible flow rate of the vertical gutter connector can be sufficiently large. Is possible. However, in recent years, the wide eaves gutter 10 mentioned above has become
Narrow and tall eaves gutters with a capacity similar to that of 0 are now in widespread use, so using a threaded vertical gutter connector like the one described above reduces the diameter of the insert member 50. I just couldn't get it big enough. That is, the diameter of the hole 101 shown in FIG.
D ₁ needs to have a dimension corresponding to the sum of the diameter D ₂ of the insertion member 50 and twice the wall thickness T of the cylindrical body 51 including the thread. The bottom wall of the eaves gutter that can accommodate this must be wide enough to accommodate the flange 52. However, with eaves gutters that are narrow and tall, it may not be possible to create a hole with a diameter equivalent to D ₂ + _2T above in the bottom wall of the eaves gutter due to its narrow width. There is no choice but to use an insert member. However, if this is done, it may become impossible to secure an allowable flow rate commensurate with the capacity of the eaves gutter. Therefore, in the past, in order to ensure a sufficient allowable water flow rate, the lack of water flow from one vertical gutter connector was compensated for by placing vertical gutter connectors at multiple locations on the eaves gutter. was. However, in this case, the problem is that the number of vertical gutters increases, making them unsightly.

To solve this problem, a vertical gutter connector has been proposed in which the cylindrical body of the receiving member is immediately fitted externally in a sliding manner to the cylindrical body of the insertion member, instead of the conventional screw-fitting type. Ta. according to this,
Since it is no longer necessary to provide a thread on the cylindrical body of the insertion member, it is possible to increase the diameter of the cylindrical body by a dimension equivalent to twice the height H of the thread (see Figure 5), and that is all. Allowable flow rate can be increased. However, this has the following problem.

[Problem that the invention attempts to solve]

That is, the cylindrical body of the insertion member and the cylindrical body of the receiving member, as well as the bottom wall of the eaves gutter and each flange of the insertion member and the receiving member, are joined with a slow-drying adhesive (as is the case with the vertical gutter connector). (Quick-drying adhesives are not suitable for position adjustment, etc.), and it is necessary to ensure watertightness between them and to prevent the vertical gutter connector from separating from the eaves gutter. Once the fittings are temporarily attached, they must remain in place until the adhesive dries.

However, simply externally fitting the cylindrical body of the receiving member into the cylindrical body of the inserting member does not provide a sufficient temporary fixing effect, and the two members may become pushed out from each other over time. Further, due to variations in the molded dimensions of the insertion member and the receiving member and thermal expansion and contraction after molding, looseness may occur when the two members are fitted together. When such a situation occurs,
Gaps are created at various locations on the adhesive surface, and the adhesive is no longer able to exert sufficient adhesive strength.

This invention was developed in view of the above circumstances, and even if it is a sliding type vertical gutter connector, there will be no gap on the adhesive surface over time after it is temporarily attached to the eaves gutter, and the adhesive can be easily bonded with adhesive. It is an object of the present invention to provide a vertical gutter connector with increased strength.

[Means for solving problems]

In order to solve the above problems, the connector of the present invention includes an insert member having a flange at the upper end of a cylinder that is fitted into a hole made in the bottom wall of the eave gutter, and a flange attached to the cylindrical body of the insert member. It consists of a receiving member with a flange provided at the upper end of a cylindrical body to be fitted externally, a protrusion is provided on the inside of the cylindrical body of the receiving member, and a recessed hole having a width slightly smaller than the width of the protrusion. The gist is that the cylindrical body of the insertion member is provided in the shape of a notch extending upward from the lower end of the cylindrical body.

[Effect]

In the above means, when the cylindrical body of the insertion member and the cylindrical body of the receiving member are inserted and externally fitted, the protrusion provided inside the cylindrical body of the receiving member is inserted into the notch provided in the cylindrical body of the insertion member. It fits into a shaped recess.
Since the width of the recess is slightly smaller than the width of the protrusion, the protrusion fitted into the recess expands the cylindrical body of the insert member and presses it against the cylindrical body of the receiving member. Therefore, the insertion member and the receiving member are reliably fixed at the time of temporary fixing to the eaves gutter, and a situation where a gap occurs in the adhesive surface over time after being temporarily fixed to the eaves gutter is prevented.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 indicates an insertion member and 2 indicates a receiving member.

The insert member 1 includes a flange 12 provided at the upper end of a rectangular cylindrical body 11. The cylinder 11 in the illustrated example has a substantially rectangular cross section with narrow walls 11a formed at the four corners, and wide side walls 11b, 11b facing each other.
A notch-shaped recessed hole 13 is formed in the center of the housing from the lower end upward. The width of the recessed hole 13 becomes narrower as it goes upward, and the width near the upper end of the recessed hole 13 is slightly smaller (approximately 0.05 to 0.5 mm) than the width of the projection 23, which will be described later. The width of the lower end of the recessed hole 13 is slightly larger than the width of the protrusion 23. The width L ₁ of the flange 12 from the side walls 11b, 11b of the cylindrical body 11 is the same as that of the other side wall 11.
c, smaller than the output width L ₂ from 11c.

On the other hand, the receiving member 2 also has a flange 22 provided at the upper end of a rectangular cylindrical body 21. The cylindrical body 21 is configured to have the same shape as the cylindrical body 11 of the insert member 1 so that it can be externally fitted into the cylindrical body 11, and protrusions 23, 23 are provided on the inside of the cylindrical body 21.
In addition, the flange 22 is also inserted into the flange 12 of the insert member 1.
It is configured in the same shape.

Figures 2 and 3 show how to connect the above connector to the eaves gutter 100.
The vertical gutter 110 is shown connected to the connector. As is clear from the figure,
The cylindrical body 11 of the insertion member 1 is fitted into a hole 101 formed in the eaves gutter 100, and the cylindrical body 21 of the receiving member 2
is externally fitted to the cylindrical body 11 of the insert member 1, and the vertical gutter 1
10 is externally fitted onto the cylindrical body 21 of the receiving member 2. In this state, the bottom wall 102 of the eaves gutter 100 is connected to the flange 12 of the insert member 1 and the flange 2 of the receiving member 2.
2 and are pressed together. Further, the protrusion 23 is pushed into the vicinity of the upper end of the recessed hole 13 whose width dimension is smaller than that of the protrusion 23 . Accordingly, the cylindrical body 11 of the insertion member 1 is pushed apart laterally by the protrusion 23, and its side walls 11c, 11c are pressed against the cylindrical body 21 of the receiving member 2. Along with this pressure,
A force acts to warp the side walls 11b, 11b of the insertion member 1 inward, but if a collar 23a is provided at the tip of the protrusion 23 as shown, this collar 23a will engage with the inner surface of the side walls 11b, 11b. and the side wall 11b,
11b is prevented from warping.

Further, the flange 12 of the insert member 1 is attached to the eaves gutter 100 so that the narrow part matches the width direction of the eaves gutter 100.
is embedded in.

According to the above, by pressing the cylinder 11 of the insertion member 1 and the cylinder 21 of the receiving member 2, both members 1,
2 is securely fixed. This state is a temporary state. This kind of temporary fixing is necessary because adhesive has been applied to the cylindrical body 11 and flange 12 of the insertion member 1 and the cylindrical body 21 and flange 22 of the receiving member 2 in advance, and when this adhesive dries. This is because it takes time.

FIG. 4 shows a modification of the recessed hole 13. The recessed hole 13 in the same figure has a constricted part 13a in its upper part, and when the protrusion 23 is pushed into the recessed hole 13, it rides over the constricted part 13a and engages with the constricted part 13a. Due to the restoring force of the cylindrical body 11 that has been pushed and expanded, the protrusion 23 is pushed into the concave hole 13.
This is to prevent you from escaping.

[Effect of idea]

The present invention can be implemented as described above,
By simply slidingly inserting the cylindrical body of the insertion member and the cylindrical body of the receiving member, both members can be joined and the connector can be temporarily fixed to the eaves gutter. That is, when the concave hole formed in the cylindrical body of the inserting member is pushed into the protrusion provided on the cylindrical body of the receiving member, the cylindrical body of the inserting member is pushed and expanded by the protrusion, and the cylindrical body of the receiving member is pushed into the cylindrical body of the receiving member. pressed elastically. Therefore, both members are reliably fixed by pressing the respective cylindrical bodies together. Therefore, there will be no gap between the bonding surfaces during the temporary fixing period due to heat expansion and contraction or dimensional variations after molding the two parts, and the bonding strength of the adhesive will be increased, ensuring reliable watertightness. The above will also be valid.

In the above embodiment, the cylindrical bodies of the insertion member and the receiving member have a rectangular cross section and are connected to a square vertical gutter. It may also be possible to connect it to the gutter. The cylindrical body in this case may have a perfect circular cross-section or an oval cross-section, but in order to ensure a sufficient allowable flow rate, it is desirable to have an oval cross-section.
