Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a connection structure for eaves gutters.

(Prior art) Conventionally, in order to connect eaves gutters, an ear edge is formed on the circular upper edge of the eaves gutter, a gutter joint is also formed to match the shape of the eaves gutter, and an ear edge is formed on the circular upper edge. A holding part is provided, the eaves gutter is fitted into the gutter joint, the rim is fitted into the rim holding part, and the eave gutter and the gutter joint are joined using an adhesive.

In addition, as a method for connecting eaves gutters that does not use adhesive,
No. 9-3084 discloses that a notch is provided in advance in the edge holding part of the gutter joint, an eaves gutter is inserted into the gutter joint, and a cut and raised piece of the edge of the eaves gutter that corresponds to the notch is inserted into the notch. It is proposed to engage with

(Problem to be solved by the invention) However, in the former example above, in the case of the worst combination with the maximum and minimum dimensional errors between the eaves gutter body and the gutter joint, the fit is tight and the work is difficult. Furthermore, there were drawbacks such as the possibility of damage, and conversely, the fitting was loose and easy to come off.

In addition, in the latter example, since the notch of this joint has a structure that opens at the open edge of the ear, the cut-and-raised piece of the ear can easily come out of the notch due to deformation such as inward bending of the eaves gutter. It had the drawback that it easily came off.

The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and includes providing a retaining protrusion upright on the edge of the eave gutter body and forming a hook portion on the edge holding part of the gutter joint. To provide an eaves gutter connection structure capable of connecting an eaves gutter by removing and stopping it with a one-touch operation.

(Means for Solving the Problems) The present invention solves the above-mentioned problems by the configuration described in the claims of the utility model registration.

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

In FIG. 1, 1 and 1' are eave gutter bodies, and these two eave gutter 1 and 1' are connected by a gutter joint 2.

The eaves gutter bodies 1 and 1' have the same shape.

The eaves gutter main body 1 is made of a flexible material such as synthetic resin and has a U-shaped cross section, and has an ear edge 3 on the upper edge of the circle, and a retaining projection on the upper edge of the ear edge 3 near the connecting end. 4 are integrally erected.

As shown in FIG. 5, the engaging protrusions 4, 4' are constructed as separate parts from the eave gutter bodies 1, 1', and are removably attached to the holes 10 provided in the ear edges 3. You can do it like this.

Also, the gutter joint 2 has a U that is larger by the wall thickness of the eaves gutter bodies 1 and 1'.
It is formed in the shape of a short gutter with a letter-shaped cross section, and a C mark is placed on the upper edge of the circle.
Letter-shaped ear rim holding parts 5 are installed facing each other with the opening side facing inward, and two sets of hook parts 6° 6' are located near the center in the longitudinal direction of the ear rim holding parts 5. They are arranged symmetrically.

The hook portion 6 includes an insertion lower in which a notch is provided from the inner side end of the ear edge holding portion 5 to the outside of the gutter joint 2, and a central portion of the ear edge holding portion 5 that is bent from the insertion lower. It consists of a notch part 8 which is notched in the direction and the inner part is enlarged in the lower insertion direction.

The notch 8 forms a hook 9 that allows the locking protrusion 4 to move from the center of the ear edge holding part 5 to the longitudinal end, but prevents the locking projection 4 from moving in the opposite direction.

(Function) Next, the case where the eaves gutter bodies 1, 1' are connected to the gutter joint 2 will be explained.

First, as shown in Fig. 2, align the engagement protrusion 4 of the eaves gutter body 1 with the insertion lower of one of the hook parts 6 of the ear edge holding part 5 of the gutter joint 2, and then move the eaves gutter body 1 in the width direction. Expand outward and insert the engaging protrusion 4 deep into the insertion lower as shown in FIG. 3, and in this state slide the eaves gutter body 1 toward the center of the gutter joint 2 in the connection direction C.

As a result, the eaves gutter main body 1 is fitted and placed on the gutter joint 2, the ear edge 3 is fitted into the ear edge holding part 5, and the retaining protrusion 4
moves to the inner part of the notch 8 and engages with the hook 9 as shown in FIG.

The engagement between the engagement protrusion 4 and the hook 9 prevents the eaves gutter body 1 from being removed.

Next, the eave gutter body 1' is connected to the gutter joint 2 in the same manner.

(Effect of the invention) Since the connection structure of the eaves gutter of the present invention is configured as described above, the engaging protrusion of the eaves gutter body is symmetrical with respect to the longitudinal center of the ear edge holding part of the gutter joint. Since it engages with two sets of hooks, there is no need to forcefully fit the gutter joint by applying excessive force as in the past, and the connection can be made without any problems even when the dimensional error is at its maximum or minimum. The retaining protrusion of the eaves gutter main body is held in the notch part which is enlarged at the back following the insertion opening of the ear edge holding part of the gutter joint, and the eaves gutter main body is reliably prevented from being removed.

In addition, since the eaves gutter body can be expanded and slid to connect with a single touch, workability is good and work at high places can be performed easily.

Furthermore, even if the main body of the eaves gutter tries to deform inwardly, the retaining protrusion does not come off from the hook of the gutter joint, which has the effect of suppressing such deformation of the eaves gutter.
