Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chain gutter, and more specifically, an upper hook portion 2 and a lower hook portion 3 are provided at the bottom end of a hanger 1, and the upper and lower hook portions 2,
A substantially horizontal spiral portion is formed in the middle of the cylinder body 5, and a plurality of mounting fixing pieces are provided at different heights approximately at the vertical center of the cylinder body 5, and the hanger 1 is inserted into the cylinder body 5. Then, a certain mounting fixing piece 6 protruding from the cylinder body 5 is placed above the almost horizontal spiral portion 4 of the hanger 1, and another mounting fixing piece 6 is placed below the spiral portion 4. to form a chain element a,
This relates to a chain gutter characterized in that an upper hook part 2 of a lower chain element a is suspended from a lower hook part 3 of an upper chain element a.

In conventional gutter chains, as shown in Fig. 1, an inverted U-shaped upper hanger 2' and a U-shaped lower hanger 3' are separate members, and these upper and lower hangers 2', 3 Since the cylindrical body 5' is separately attached to the cylindrical body 5', the structure of the cylindrical body 5' becomes complicated, and there are also problems in terms of strength.

In addition, since the upper and lower hangers 2' and 3' are not straight, it is impossible to prevent rainwater from scattering, and it is necessary to take measures to prevent rainwater from scattering on the cylindrical body 5'.

The present invention was made in view of the shortcomings of the conventional example described above, and its purpose is to integrate the upper and lower suspenders into a single suspender, thereby simplifying the structure and improving strength. Moreover, it is an object of the present invention to provide a chain gutter which can also prevent rainwater from scattering with a hanger.

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

Reference numeral 1 designates a hanger, and the upper and lower ends of the hanger 1 are provided with an upper hook portion 2 and a lower hook portion 3, respectively, and an approximately horizontal spiral portion 4 is formed between the lower hook portions 2 and 3. be.

The spiral portion 4 may have a single turn as shown in FIG. 4, or may have multiple turns as shown in FIG.

It is preferable that the hanger 1 is formed by bending a single piece of steel wire, but if necessary, the steel wire may be bent or molded from synthetic resin.

Reference numeral 5 denotes a cylindrical body, and a mounting fixing piece 6 is provided protruding from the inner periphery of the approximately central portion of the cylindrical body 5 in the vertical direction.

The inner diameter of the mounting fixing piece 6 is smaller than the outer diameter of the spiral portion 4.

As shown in FIG. 3, the chain element a is constructed by inserting the hanger 1 into the cylindrical body 5 and locking the outer periphery of the spiral portion 4 to the fixing piece 6.

As shown in FIG. 3, the mounting/fixing piece 6 is provided with a plurality of mounting/fixing pieces 6 sectioned, each having a different height. 6 is placed under the spiral portion 4 so that the cylinder body 5 can be firmly fixed.

The complex gutter A, which is constructed by connecting these chain elements a to the top hook 2 and the bottom hook 3 vertically, is used by being suspended below the water collector 7. be.

As described above, the present invention provides an upper hook part and a lower hook part at the upper and lower ends of the hanger, respectively, and forms a substantially horizontal spiral part between the upper and lower hook parts, and inserts the hanger into the cylinder. The chain element is formed by locking the spiral part of the hanger to the mounting fixing piece protruding from the circumference, and the upper hook part of the lower chain element is suspended from the lower hook part of the upper chain element. The hanger is not separated into an upper hanger and a lower hanger as in the past, but is formed as a single piece, which simplifies the structure of the hanger and improves its strength, and the mounting fixing piece is locked to the spiral part. This has the advantage that the upper and lower parts of the hanger can be formed into a straight line rather than a U-shape, and the hanger can prevent rainwater from scattering.

In addition, a plurality of mounting fixing pieces are provided at approximately the vertical center of the cylinder at different heights, and a hanging piece is inserted into the cylinder and protrudes from the periphery of the cylinder. Since the hanger and the cylinder were placed on top of the almost horizontal spiral part, and the other mounting fixing piece was placed below the spiral part, the hanger and the cylinder were placed on top of the mounting fixing piece and the spiral part. The cylindrical body is firmly fixed by engagement with the hanger, and the cylindrical body does not float up against the hanger and shake, especially when a lifting force from the wind is applied.

Moreover, even though the cylinder body was prevented from floating up with respect to the hanger, the mounting fixing piece and the almost horizontal spiral part were located almost in the vertical center of the cylinder body, The curved shape required for locking does not protrude from the upper or lower part, and as a result, rainwater can be prevented from scattering.

Moreover, the elasticity of the spiral portion can absorb the impact applied to the chain gutter, which has the advantage of preventing the cylindrical body from cracking.
