Description

[Detailed description of the invention] The present invention has eave gutter ear fitting recesses on both sides of the gutter-like body to form the joint body, eave gutter connecting parts at both ends of the soft sheet body, and a bellows-like elastic part in the center. one eave gutter connection part of the joint inner layer body is fixed to the inner peripheral surface of one end side of the joint body, and the other eave gutter connection part is fixed to the other end side of the joint body. This relates to an eaves gutter joint that is slidably installed on the inner peripheral surface of the eaves gutter.

In this type of eaves gutter joint, both eaves gutter connection parts of the inner layer of the joint are fixed to the outer surface of the connecting ends of the eaves gutter, and both eave gutter ear fitting recesses of the gutter-like body are fitted into the eaves gutter ears, respectively. At the eaves gutter connection part on the fixed side, the connecting end of the eave gutter is fixed to the eaves gutter joint, and at the eaves gutter joint on the sliding side, the connecting end of the eave gutter is fixed to the eaves gutter joint. Since it is held in the gutter joint so that it can move forward and backward, both eaves gutters are connected so that they can expand and contract, and the expansion and contraction of the eaves gutters due to temperature changes is absorbed, so that the eaves gutters do not deform.

Therefore, in this type of eaves gutter joint, it is desirable that the eave gutter connection portion on the sliding side slide smoothly while being fixed to the outer surface of the connecting end of the eaves gutter.

The eaves gutter joint of this invention was devised in view of the above points,
That is, in the eaves gutter joint described above, the eaves gutter connection part on the fixed side of the joint inner layer is formed thicker than the eave gutter connection part on the sliding side, and both edges thereof are fitted with the eaves gutter ears of the gutter-like body. It is characterized by extending into the recess, so that the eaves gutter connection part on the sliding side slides smoothly while being fixed to the outer surface of the connection end of the eaves gutter, and the eave gutter connection part on the sliding side The eaves gutter connection end is more firmly fixed to the outer surface of the eaves gutter connection end.

Hereinafter, the present invention will be explained based on the drawings.

The eaves gutter joint A shown in FIG. , a bellows-like elastic part 5 is provided at both ends of the soft sheet body 3 at the center of the eaves gutter connection parts 4, 4 to form a joint inner layer body, and one of the eave gutter connection parts 4 of the joint inner layer body is provided.
is fixed to the inner circumferential surface of one end of the joint body a by adhesive or welding, etc., and the other eave gutter connection part 4' is slid onto the inner circumferential surface of the other end of the joint body a. The eaves gutter connection part 4 on the fixed side of the joint inner layer body is formed thicker than the eave gutter connection part 4' on the sliding side, and both sides of the eave gutter connection part 4 are made to be freely installed. It is characterized in that the edge extends into the eave gutter ear fitting recess 2 of the gutter-like body 1 to form an extended portion 6.

When the eaves and gutter openings are connected using the eaves and gutter joint A, the result will be as shown in FIGS. 2 and 3.

FIG. 2 shows the fixed side, and the eaves gutter connecting portion 4 of the joint inner layer is fixed to the outer surface of the connecting end of the eaves gutter opening with adhesive.

Since the eaves gutter connecting portion 4 is formed thicker than the other eaves gutter connecting portion 4', the connecting end of the eaves gutter opening is connected to the eaves gutter connecting portion 4.
It is firmly held and fixed by the joint body a via the joint body a.

FIG. 3 shows the movable side, and the eave gutter connecting portion 4' of the inner layer of the joint is fixed to the outer surface of the connecting end of the eave gutter opening with adhesive in the same way as on the fixed side.

However, the eaves gutter connecting portion 4' is thinner than the eaves gutter connecting portion 4 on the fixed side, and both side edges of the eaves gutter connecting portion 4 on the fixed side are inside the eaves gutter ear fitting recess 2 of the gutter-like body 1. Since the connecting end of the eaves gutter on the fixed side is firmly held and fixed, the connecting end of the eaves gutter on the sliding side is The part is held by the joint body a so that it can slide along with the eave gutter connection part 4' by the amount of expansion and contraction of the bellows-like extensible part 5.

Here, since the joint body a is pushed and expanded by the eaves gutter on the fixed side, the gutter-like body 1 is expanded on the sliding side.
A gap 7 is created between the inner surface of the eaves gutter connection part 4' and the outer surface of the eaves gutter connection part 4', and there is nothing between the inner surface of the eaves gutter ear fitting recess 2 and the outer surface of the eaves gutter ear part 8, and a large gap 9 is created. Therefore, the connecting end of the eaves gutter opening can slide smoothly together with the eaves gutter connecting part 4'; on the other hand, on the fixed side, it receives most of the holding force of the joint body a and is more firmly fixed. It will be done.

In the present invention, the joint body is made of hard synthetic resin, metal, etc., and the joint inner layer is made of hard synthetic resin, synthetic rubber, etc.

As mentioned above, the eaves gutter joint of the present invention has eave gutter ear fitting recesses provided on both sides of the gutter-like body to form the joint body, eave gutter connecting parts at both ends of the soft sheet body, and a bellows-shaped expandable part in the center. is provided as a joint inner layer body, one eaves gutter connection part of the joint inner layer body is fixed to the inner peripheral surface of one end side of the joint body, and the other eaves gutter connection part is fixed to the other end of the joint body. In the eaves gutter joint that is slidably installed on the inner circumferential surface of the inner layer of the joint, the eave gutter connection part on the fixed side of the joint inner layer is formed thicker than the eave gutter connection part on the sliding side, Since both edges of the gutter extend into the eaves gutter ear fitting recess of the gutter-like body, the eaves gutter connection part on the sliding side slides smoothly while being fixed to the outer surface of the connecting end of the eaves gutter. At the same time, the eaves gutter connecting end on the fixed side is more firmly fixed to the outer surface of the connecting end of the eaves gutter.
