JPS5940494Y2 - Chain gutter - Google Patents

Description

[Detailed description of the invention] The present invention relates to a chain gutter, and more specifically, a core body 3 in which straight portions 1 and spiral spring portions 2 are alternately repeated at a constant pitch is suspended in the vertical direction, and the spring Spring part 2 around the outer periphery of part 2
This relates to a chain gutter formed by surrounding a cylindrical body 4 having approximately the same length as the cylindrical body 4 and locking a protrusion 5 provided on the inner periphery of the cylindrical body 4 to a spring portion 2.

Conventionally, the chain element 6 is composed of an upper hanger 7, a lower hanger 8, and a cylinder 4, and the upper hanger 7 of this chain element 6 is suspended from the lower hanger 7 of the chain element 6 above it. In this way, a chain gutter was constructed.

Therefore, it takes a lot of time to assemble and is structurally weak.
The drawback was that the length could not be adjusted up and down.

The present invention was developed in view of the drawbacks of the conventional examples mentioned above, and its purpose is to have a single core running through the entire body, which is strong, easy to assemble, and allows the spring part to expand and contract. To provide a chain gutter whose length can also be adjusted.

The present invention will be explained in detail below with reference to the accompanying drawings.

Reference numeral 3 denotes a vertically long core made of a curved metal wire such as a steel wire, in which a straight portion 1 and a spiral spring portion 2 are alternately provided at a constant pitch. It expands and contracts elastically.

Reference numeral 4 denotes a cylindrical body made of a thermoplastic synthetic resin such as hard polyvinyl chloride, and a protrusion 5 is provided on the inner periphery of the cylindrical body 4 .

The inner diameter of the projection 5 is smaller than the outer diameter of the spring portion 2.

Then, the core body 3 is inserted from the end into the cylinder body 4, which has approximately the same length as the spring part 2, and the cylinder body 4 is advanced along the spring part 2 while being screwed, until the spring part The cylinder body 4 is fitted so as to surround the outer periphery of the spring portion 2 by locking the protrusion 5 on the cylindrical body 4.
The cylinder body 4 is attached by rotating the cylinder body 4.
You can also adjust it up and down.

Further, since there is no need to turn the cylinder 4 in the straight portion 1 at this time, the cylinder 4 can be attached more easily than in the case of the core body 3 provided with a spring portion over the entire length.

In order to make it easier to turn and move the cylinder 4 in this manner, it is preferable to provide a plurality of projections 5 and to vary the height of each projection 5 in accordance with the pitch of the spring portions 2.

As shown in Figure 2, the upper end of this core body 3 is fixed to a water collector 9, and the lower end is fixed to a receiver 10 to prevent it from swinging. 2
Since the length can be adjusted by expanding and contracting, the chain gutter can be installed perfectly.

In another embodiment, the cylindrical body 4 may be divided into two parts, and the cylindrical body 4 may be assembled and attached with the spring portion 2 in between.

As described above, the strength of the gutter chain is increased because one core runs through the entire gutter chain, and since the core body has a spring part, the core body elastically expands and contracts at the spring part, and the gutter chain is strengthened. The length of the gutter can be adjusted, and the protrusion is locked to the spring part, and a cylindrical body equal to the length of the spring part is attached to the outer periphery of the spring part.
The spring part is hidden and only the straight part of the core body is visible, which gives an excellent appearance, and also has the advantage that this straight part can rectify rainwater and prevent rainwater from scattering.

In addition, you only need to pass the core through the cylinder, which has the advantage of reducing assembly effort and making assembly easier.The vertical position can be adjusted by turning the cylinder, and the cylinder can be attached to the core while rotating. In some cases, there is no need to turn the cylinder on straight sections, making installation easier.
