Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a gutter swivel elbow used as a joint for a gutter or a vertical gutter.

[Conventional technology]

Conventionally, this type of gutter free elbow was made by Jikosho.
Generally, a pipe made of large and small curved pipes fitted so as to be slidable and rotatable, as shown in Japanese Patent No. 57-11059, was used.

[Problem that the invention attempts to solve]

However, when adjusting the angle of such a gutter elbow, there is no problem because it can be freely selected depending on the fitting degree of the large and small bent pipes, but when adjusting the direction, since the fitted large and small bent pipes are rotated, It naturally had its limits.

This invention was devised to eliminate the drawbacks of the conventional products described above, and is intended to provide a flexible elbow for a gutter whose angle and direction can be easily selected according to the purpose.

[Means to solve the problem]

The flexible elbow for gutter of this invention was devised in view of the above, and has a square connecting part at one end where the front and rear walls bulge out in an arc shape, and a square connecting part at the other end where both side wall faces bulge out in an arc shape. a curved cylindrical pipe A having one end, and a connecting portion having a connecting portion to connect a square gutter at one end, and an arc-shaped connecting portion having opposing wall surfaces bulged in an arc shape to fit into the square connecting portion or the square connecting portion at the other end; Consisting of straight cylindrical bodies B, B, each having a rectangular connecting part and a connecting part fitted into the rectangular connecting part, one straight cylindrical body B is inserted into the curved cylindrical pipe A in the front and back direction, and the other straight cylindrical body B is moved in the lateral direction. The problem was solved by connecting each of them so that they could swing freely.

〔Example〕

The embodiments of this invention shown in the drawings will be explained in more detail below. Fig. 1 is a perspective view showing an embodiment of the gutter-use adjustable elbow of this invention, and Fig. 2 is an exploded perspective view of the same. , A in the figure is a curved cylindrical tube, which has a rectangular connecting part 1 at one end where the front and rear walls a, a bulge out in an arc shape, and a rectangular connecting part 2 at the other end where both side wall surfaces b, b bulge out in an arc shape. B and B are straight cylindrical bodies having a connecting part 3 to which a square gutter is connected at one end and the square connecting part 1 or the square connecting part 2 at the other end. It consists of a straight pipe having a connecting part 4 formed by bulging out the opposing wall surfaces c and c in an arc shape so as to be rotatably fitted into the pipe.
The curved cylindrical pipe A and the straight cylindrical body B are constructed by fitting the connecting part 4 into the rectangular connecting part 1 and the rectangular connecting part 2, so that one straight cylindrical body B is connected to the curved cylindrical pipe A in the front-rear direction, and the other straight cylindrical body is B are connected to each other so as to be swingable in the lateral direction.

In addition, numerals 5 and 6 in the figure are stoppers for the curved tube A and the straight tubes B and B, which are formed with protrusions and depressions that fit into each other at the axis of rotation. be.

[Effect of idea]

Since the flexible elbow for gutter of this invention has the above-mentioned configuration, when in use, the straight cylindrical body B fitted into the rectangular connection part 1 of the curved cylindrical pipe A can be rotated in the front and rear directions of the arrows, as shown in Fig. 1. On the other hand, the angle and direction can be easily adjusted by rotating the straight cylindrical body B fitted in the rectangular connecting part 2 of the curved cylindrical pipe A in the left and right directions of the arrow. Moreover, you can choose freely.

Claims (1)

[Scope of utility model registration request] A curved cylindrical pipe A having a rectangular connecting part at one end where the front and rear walls bulge out in an arc shape and a square connecting part at the other end where both side wall faces bulge out in an arc shape, and a connecting part to which a square gutter is to be connected at one end. It consists of a straight cylindrical body B, which has a connecting part formed by bulging out the opposing wall surface in an arc shape at the other end to fit into the square connecting part or the square connecting part, and the square connecting part and the square connecting part A swivel elbow for a gutter, in which one straight cylinder B is connected to a curved pipe A in a longitudinal direction and the other straight cylinder B is swingable in a horizontal direction by fitting a connecting part.
