BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter socket used for connecting a vertical gutter.

[0002]

2. Description of the Related Art Generally, a gutter elbow is used to connect a vertical gutter to a gutter, or to connect a vertical gutter to a gutter. In this case, the bending angle between the vertical gutter and the gutter and the bending angle between the vertical gutter and the gutter are determined by the bending angle of the gutter elbow. However, since the types of gutter elbows classified by bending angle are limited, it is possible to set the inclination angle of the gutter or the gutter to a predetermined angle to correspond to the roof slope, etc. There may not be a curved angle gutter elbow.

Conventionally, in such a case, a socket formed with a predetermined bending angle between one connecting portion and the other connecting portion has been used in combination with a gutter elbow. That is, when the gutter elbow is combined with the socket, the directions of the gutter and the gutter are swung in a predetermined direction by the bending angle of the socket with respect to the axis of the connection part of the gutter elbow.

However, conventionally, since the types of sockets classified by the bending angle between the connecting portions are limited, the bending angle between the connecting gutters cannot always be set to a desired angle. Was left.
Further, if the number of types of sockets is increased so that the bending angle between the connected gutters can be set to a desired angle as much as possible, the number of types of dies must be increased, which significantly increases the manufacturing cost.

In view of the above problems, the present invention has an object to provide a rain gutter socket in which the bending angle between the connected gutters can be set to an arbitrary angle.

[0006]

In order to achieve the above object, in a gutter socket of the present invention, a first tubular body having a connecting portion at one end and a connecting portion at the other end is provided. ,
A second tubular body having a coupling portion coupled to the coupling portion of the first tubular body at one end and a connecting portion at the other end; and the coupling portion of the first tubular body and the first tubular body. The connecting portion of the two tubular bodies is formed so as to allow relative rotation of the first tubular body and the second tubular body in a direction in which the axis of the first tubular body and the axis of the second tubular body are broken. .. When the connecting portion of the first tubular body and the connecting portion of the second tubular body are formed in a substantially rectangular tube shape, the connecting portion of the first tubular body and the connecting portion of the second tubular body are joined together. Desirably, the parts are rotatably coupled to each other.

[0007]

In the socket for a rain gutter according to claim 1, the first tubular body and the second tubular body are relatively rotated in a direction in which the axis of the first tubular body and the axis of the second tubular body are broken. Therefore, the bending angle between the gutter connected to the connection part of the first tubular body and the gutter connected to the connection part of the second tubular body can be adjusted.

Further, in the rain gutter socket according to the second aspect of the present invention, since the connecting portion of the first tubular body and the connecting portion of the second tubular body are formed in a substantially rectangular tube shape, the connection between the rectangular gutters is made. It can be used for connection. In addition, since the connecting portion of the first tubular body and the connecting portion of the second tubular body are rotatably coupled, the connecting portion of the rectangular gutter and the connecting portion of the second tubular body which are connected to the connecting portion of the first tubular body are connected. When a bending angle is provided between the square gutters, the bending direction can also be adjusted.

In the figure, the socket S for the rain gutter of the present embodiment is represented by the first tubular body 1
And a second tubular body 2 and a locking ring 3.

The first tubular body 1 is provided with a connecting portion 11 at one end and a connecting portion 12 at the other end, and the connecting portion 11 has a square tubular shape corresponding to a square gutter. The connecting portion 12 is formed by changing the cross-sectional shape so that the opening end has a circular shape. In addition, at the opening end of the coupling portion 12, the recessed collar portion 1 formed in a spherical shape is formed.
21 is provided, and an annular groove 14 to which the O-ring 13 is attached is formed on the outer surface of the recessed flange portion 121.

The second tubular body 2 has a connecting portion 21 at one end and a connecting portion 22 at the other end. The connecting portion 22 has a square tubular shape corresponding to a square gutter. The connecting portion 21 is formed by changing the cross-sectional shape so that the opening end has a circular shape. Further, a bulging flange portion 211 formed in a spherical shape and a cylindrical portion 212 protruding from the tip of the bulging flange portion 211 are provided at the open end of the connecting portion 21, and Bulging collar part 211
Is in close contact with the recessed collar portion 121 of the first tubular body 1, and the cylindrical portion 212 is inserted into a round hole 122 provided in the center of the recessed collar portion 121. The cylindrical portion 212 of the second tubular body 2 is formed to have a smaller diameter than the round hole 122 of the first tubular body 1.

That is, the connecting portion 12 of the first tubular body 1 and the connecting portion 21 of the second tubular body 2 are rotatably connected to each other by being in contact with each other at their spherical surfaces, and at the same time, the first tubular body 1 is connected. Of the first tubular body 1 and the second tubular body 2 are allowed to rotate relative to each other in the direction in which the axial center of the first tubular body 1 and the axial center of the second tubular body 2 are broken, that is, in the joint structure of the universal joint. Is becoming In addition, the rotation is performed by the cylindrical portion 2 of the second tubular body 2.
12 is allowed within the range where it can move in the round hole 122 of the first tubular body 1. For example, when the cylindrical portion 212 is located at the center of the round hole 122, as shown in FIG.
When the axial center of the tubular body and the axial center of the second tubular body are coaxial with each other and the cylindrical portion 212 is displaced from the center of the round hole 122, as shown in FIG. The axis of the second tubular body is broken with respect to the axis of the body.

Further, locking projections 23 are formed at two symmetrical positions on the outer surface of the connecting portion 22 of the second tubular body 2. It should be noted that, when the connecting portion 22 is inserted into a gutter such as a gutter and connected, the locking projection 23 engages with a recess formed on the inner surface of the gutter to ensure a connection with the gutter. It is a thing.

The locking ring 3 is formed such that the outer diameter thereof is larger than the round hole 122 of the first tubular body 1 and smaller than the inner diameter of the coupling portion 12 of the first tubular body 1, and the second ring is formed.
It is fixed to the outer surface of the cylindrical portion 212 of the tubular body 2. Therefore, the locking ring 3 engages with the recessed flange portion 121 of the first tubular body 1 regardless of the angle of the axis of the second tubular body 2, so that the second tubular body 2 becomes the first tubular body 1. It prevents it from coming off.

Next, the operation of this embodiment will be described. The socket S of the present embodiment includes the axial center of the first tubular body 1 and the second tubular body 2.
Since it is possible to relatively rotate the first tubular body 1 and the second tubular body 2 in a direction in which the axis centers of the first tubular body 1 and the second tubular body 2 are connected to each other, It is possible to adjust the bending angle between the gutters connected to the connection portion 22 of.
