Description

[Detailed description of the invention] This invention relates to a chain gutter that hangs down from the eaves gutter or the entrance roof and drains rainwater.The purpose of the gutter chain is to ensure that it does not loosen even when the lower end is installed on the ground. Also, it is an object of the present invention to provide a chain gutter that is not easily swayed or rattled by wind or the like.

The present invention will be explained below based on the drawings.

The chain gutter shown in FIG. 1 is an embodiment of the present invention.

The chain gutter is constructed by connecting a plurality of chain gutter blocks a vertically as shown in FIG.

The chain gutter block a has six connecting arms 2, each upward and downward, projecting outwardly from a central part 1 of the chain gutter block a.
A locking portion 3 is provided at the tip of each connecting arm 2, the upper locking portion 3 is formed in a notched ring shape, and the lower locking portion 3 is formed in a ring shape.
It is made of highly elastic synthetic resin.

A plurality of the chain gutter blocks a are connected vertically by engaging each other with the upper locking part 3 and the lower locking part 3 of each connecting arm 2, as shown in FIG. This constitutes a chain gutter.

In the chain gutter, if the weight body 4 is connected to the lower end,
The chain gutter is stretched against the elasticity of the connecting arm 2 of each gutter block a, and the weight body 4 is installed on the ground 5, so that the length of the chain gutter is inevitably adjusted and does not slacken. In addition, since the connecting parts of each chain gutter block a are engaged at multiple points, the chain gutter does not easily swing, and each connecting part is locked in a tensioned state due to the elasticity of the connecting arm 2. Part 3
Since the two are engaged with each other, it is difficult to rattle, and since each connecting part is in a swollen state, it has excellent drainage ability.

In addition, in the chain gutter of the present invention, as shown in Fig. 3,
The chain gutter block a may be formed by vertically dividing the central part of the chain gutter block and fitting and fixing them to each other, and as shown in FIG. Connecting arms 2 protruding downward are connected to each other in pairs and are integrally formed into a bent rod shape, and the bent rod-shaped body 6 is converged at the central part 1 of the chain gutter block, and the convergence part, that is, the chain gutter block. The chain gutter block a may be formed by wrapping a metal ring-shaped piece 7 or the like around the block central portion 1 and integrating it.

Further, as in the embodiment shown in FIG. 5, if the upper locking portion 3 and the lower locking portion 3 of each chain gutter block a are formed so as to be engaged with each other in the circumferential direction, as shown in FIG. As shown in the figure, the chain gutter block a can be rotated to engage each of the locking parts 3 at the same time.

In addition, the connecting arm 2 of the chain gutter block a in the chain gutter of the present invention is
It only needs to be made of a highly elastic material, for example,
They may be made of metal or synthetic resin, and their number is not limited.

As mentioned above, the chain gutter of the present invention has a plurality of connecting arms made of a highly elastic material, each upward and downward, projecting outward from the center of the chain gutter block, and the tip of each connecting arm. A locking part is provided to form a chain gutter block, a plurality of the chain gutter blocks,
The locking portions of each connecting arm are engaged with each other to connect the top and bottom, and it is stretchable against the elasticity of the continuous arm, so it will not loosen even if the lower end is placed on the ground. In addition, since the connecting parts of the chain gutter blocks are engaged at multiple points, the chain gutter blocks are not easily swayed, and in each connecting part, the locking part 3 is pulled by the elasticity of the connecting arm. Because they engage with each other, they are less likely to rattle.
