Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bent joint for a pipe cover provided for connection of a pipe cover of an air conditioner disposed along an outer wall surface of a building. The present invention relates to a pipe cover bent joint capable of taking out a built-in drain pipe at a corner portion.

[0002]

2. Description of the Related Art Conventionally, an L-shaped tubular body is divided into two in the radial direction to form a curved gutter-shaped main body member and a lid member, and a joint is provided at a divided edge portion of the two members. A bent joint for a pipe cover in which a thin wall portion for forming a through hole in which one side abuts a divided edge portion is provided at a protruding corner portion of a main body member and / or a lid member as disclosed in Japanese Utility Model Laid-Open No. 59-13792. Generally known.

[0003]

However, the above-mentioned bent joint for a pipe cover merely forms a thin-walled portion in an appropriate position of an L-shaped bent pipe body. Construction was very complicated, requiring special jigs.

The present invention has been devised in order to solve the above-mentioned drawbacks of the conventional product, and does not require a special jig and can be easily carried out by using a jig generally used in this kind of piping work. It is an object to provide a bent joint for a pipe cover in which a through hole can be formed.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been devised in view of the above, and has been made by dividing a pipe body bent into an L-shape into two parts in a radial direction, and forming a bent gutter-shaped main body member and a lid. Forming a member,
In a bent joint for a pipe cover, a thin wall portion for forming a through hole in which one side abuts the divided edge portion is provided at a protruding corner portion of the main body member and / or the lid member while providing a joint portion at the divided edge portion of the both members, At least on both sides of the thin portion, a slit groove thinner than the thin portion is formed, and a notch is formed at the divided edge side end of the slit groove, such as pliers or scissors generally used in piping work. A bent joint for a pipe cover, characterized in that a through hole can be easily formed with a jig by, for example, twisting.

It is preferable that the slit groove is formed so as to have a width such that a saw tooth can be inserted therein and along the peripheral edge of the thin portion, and the thin portion is formed at a flat corner portion of the main body member. Preferably, it is formed.

[0007]

The bent joint for a pipe cover according to the present invention has a thin slit formed on at least both sides of the thin part compared with the thin part, and a notch formed at an end of the slit groove on the divided edge side. Therefore, the through hole can be easily formed by cutting with pliers, cutting with scissors, or the like.

FIG. 1 is an exploded perspective view showing an embodiment of a bent joint for a pipe cover according to the present invention, and FIG. 2 is an exploded perspective view of a main body member of the same. It is a figure which shows a part expansion perspective view.

In the figures, A and B are a main body member and a lid member which are formed by dividing a pipe having a substantially octagonal cross section, which is bent into an L-shape, into two in the radial direction to form a trough. Are provided with joining portions 1 to be joined to each other, and each protruding corner portion 2 is formed in a planar shape.

In the figure, reference numeral 3 denotes a protruding corner portion 2 of the main body member A.
Are formed so that the upper side thereof abuts on the divided edge.

In the figure, reference numeral 4 denotes a slit groove formed in a U-shape along the periphery of the thin portion 3, which is formed to be thinner than the thin portion 3. , Code 5
Is a notch formed by a notch at the end of the slit groove 4 on the divided edge side.

In the drawing, reference numeral 6 denotes a main body member A and a lid member B.
Reference numeral 7 denotes a stopper provided for fixing a pipe cover (not shown).

[0013]

As is apparent from the above description, the bent joint for a pipe cover of the present invention has a thin slit formed on at least both sides of a thin portion as compared with the thin portion, and a divided edge side of the slit groove. Since it has a configuration in which a notch is formed at the end, without using a special jig such as a hole saw as in conventional products, a jig such as pliers or scissors generally used in plumbing work, The through-hole can be easily formed by screw cutting or the like.
