Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eaves gutter joint, and its main purpose is to removably fit a bellows body into the joint body so that the bellows body can be replaced, and to make the bellows body replaceable. To provide an eaves gutter joint in which the flow of rainwater is not obstructed by the body.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

The joint body 1 has approximately the same shape as the eaves gutter 6, and is made of hard synthetic resin such as hard vinyl chloride resin.
An engagement hole 3 penetrating from the inside to the outside of the bottom portion 7 is formed approximately at the center in the longitudinal direction. On the other hand, the bellows body 2 is made of a soft synthetic resin such as soft vinyl chloride resin, and the ear portion 8
It has a cross section that is substantially the same as the joint body 1 except that it is not provided with, and is arranged along the inner surface of the joint body 1. A bellows part 9 is formed in the longitudinal center of the bellows body 2, and the bellows part 9 is arranged in a direction perpendicular to the longitudinal direction of the joint body 1.
It is stretchable in the longitudinal direction. On both longitudinal sides of the bellows part 9, sliding contact parts 10 are provided at the end of the eaves gutter, which are integral with the bellows part 9. Further, on the back surface of the bellows part 9, a protrusion 5 is provided which projects downward and is integral with the bellows body 2, and this protrusion 5 consists of a neck part 11 and a head part 4 which is larger than the engagement hole 3. This protrusion 5 is press-deformed and press-fitted from the inside of the engagement hole 3 of the joint body 1, and the periphery of the head 4 is locked to the outer periphery of the engagement hole 3 to connect the joint body 1 and the bellows body 2. It has been done. Therefore, when connecting the eaves gutter 6, insert the end of the eave gutter 6 from the longitudinal direction of the joint body 1, bring the tip of the eave gutter 6 into contact with the bellows part 9, and adjust the insertion length of the eave gutter 6. Adjust with the bellows part 9 and install the eaves gutter 6.
Concatenate. In the present invention, as described above, a bellows body made of soft synthetic resin and stretchable in the longitudinal direction of the eaves gutter is arranged and attached along the inner surface of the approximately central portion in the longitudinal direction of the joint body of the eaves gutter. Therefore, the ends of the eaves gutters inserted from both sides in the longitudinal direction of the joint body can be brought into contact with the bellows body, and the bellows body can be expanded and contracted to adjust the insertion length of the eaves gutters and connect the eaves gutters.
The insertion length of the eaves gutter can be adjusted, so even if there is a slight dimensional error in the length of the eaves gutter, it can be connected reliably, and the length of the eaves gutter will not change due to expansion or contraction after installation. In addition, an engagement hole is formed approximately in the longitudinal center of the joint body, and an engagement hole is formed on the outer peripheral surface of the bellows body made of soft synthetic resin to protrude integrally with the bellows body. By forming a protrusion with a head larger than the diameter of the engagement hole at the distal end thereof, and press-fitting the protrusion into the engagement hole, the head is locked to the outer periphery of the engagement hole and the joint body is closed. Since the bellows is fixed to the joint body, the joint body and the bellows body can be freely attached and detached, and the bellows body, which is prone to fatigue due to expansion and contraction, has the advantage of being replaceable.Moreover, the joint body and the bellows body can be firmly connected. This has the advantage that the bellows body will not easily come off from the joint body even if a relatively large external force is applied when inserting an eaves gutter.

In addition, a bellows body is arranged along the inner circumferential surface of the joint body, an engagement hole is formed approximately in the longitudinal center of the joint body, and a bellows body is provided integrally with the bellows body to protrude from the outer circumferential surface of the joint body. By forming a protrusion with a head larger than the diameter of the engagement hole at the tip and press-fitting the protrusion into the engagement hole, the head is locked to the outer periphery of the engagement hole and a bellows is formed on the joint body. Since it is fixed, there is no protrusion on the inner surface of the bellows body through which rainwater passes, and the flow of rainwater is not obstructed, which has the advantage that rainwater can flow smoothly from above the water to below the water. It is something. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of one embodiment of the present invention, FIG. 2 is a front view of the same, and FIG. 3 is a sectional view taken along line X-X'' of the same, in which 1 is a joint body; 2 is a bellows body, 3 is an engagement hole, 4 is a head, and 5 is a projection.

Claims (1)

[Claims] 1. A bellows body made of soft synthetic resin that can be freely expanded and contracted in the longitudinal direction of the eaves gutter is arranged along the inner circumferential surface of the eaves gutter at approximately the center in the longitudinal direction of the eaves gutter joint body. An engagement hole is formed in the bellows body, and a protrusion having a head larger than the diameter of the engagement hole is formed at the distal end of the bellows body, which projects integrally with the bellows body, and the protrusion is formed in the engagement hole. An eaves gutter joint characterized in that the bellows is fixed to the joint body by press-fitting the head part to the outer periphery of the engagement hole and fixing the bellows to the joint body.
