JP5601680B2 - Elbow type piping cover - Google Patents

Description

  The present invention provides, for example, piping arrangement in a piping cover structure in which a plurality of types of piping covers covering piping such as refrigerant pipes and drain hoses are arranged along a piping arrangement route along a mounting surface such as a wall surface. The present invention relates to an elbow-type piping cover disposed at a bent portion of an installation route, and more particularly, to a technique for making the entire bending angle freely changeable in response to a change in the angle of a bent portion of a piping arrangement route.

  Conventionally, as this type of elbow-type piping cover, a certain range around a pivot point in which an outer half on one end side in the axial direction (piping arrangement direction) and an inner half on the other end side are formed between both members. There is a configuration in which the bending angle of the cover can be changed by the relative rotation of both within a certain range (see Patent Documents 1 and 2 below).

JP 2001-74276 A JP 9-166337 A

  However, in the above conventional technique, in order to prevent a gap from being formed between the outer half body and the inner half body regardless of the bending angle of the cover, the left and right side wall portions of the inner half body are connected to the pivot. Because it is necessary to configure the arcuate wall with a small radius around the fulcrum, when the range of change of the bend angle is widened, the inner side of the cover where the tip of the arcuate wall of the inner half serves as the piping storage space Will protrude to the side.

  Therefore, when widening the change range of the bend angle, in order to secure the pipe storage space, the connection part between the inner half and the outer half is the amount that the tip of the arcuate wall of the inner half projects into the pipe storage space. Therefore, there is a disadvantage that the manufacturing cost is increased and the appearance is unfavorable.

  Also, since the bending radius of the pipes to be stored must be changed as the bending angle is changed by turning the connecting portion between the inner half and the outer half, for example, the bending angle of the cover is increased. In some cases, the piping is bent with a small bending radius, which may cause inconveniences such as breakage of the piping and a decrease in the service life.

  The present invention has been made in view of the above-described actual situation, and the main problem is that the bending angle can be freely changed, and both the manufacturing cost and the appearance are excellent, and the piping to be stored is damaged. In addition, the present invention provides an elbow-type piping cover that is less prone to inconveniences such as reduced service life.

Engagement means capable of engaging the base member of the inner half and the base member of the outer half in a slidable manner within a certain range along the arcuate axis in the mounting posture with respect to the mounting surface; It is in the point provided.

  That is, according to the above configuration, the inner half base member and the outer half base member are desired by sliding movement within a certain range between the inner half base member and the outer half base member. It is possible to make the posture to reveal the piping covering posture of, through the mounting operation of both base members to the mounted surface, the placement operation of piping, the mounting operation of both lid members to both base members, Piping can be covered with a desired piping covering posture.

  That is, according to the above configuration, the entire bending angle is changed by sliding movement within a certain range between the base member of the inner half and the base member of the outer half, so even when the bending angle is increased, As in the prior art, it is possible to eliminate the inconvenience that the tip of the arcuate wall portion of the inner half projects into the pipe storage space, thereby making it possible to reduce the dimension in the width direction as much as possible, It can be excellent in both production cost and appearance.

  In addition, since the sliding movement of the base member of the inner half and the base member of the outer half is kept within a certain range by the engagement means, for example, both the base members are separated by a slide operation exceeding a certain amount. Can be effectively suppressed.

  Also, since the bending angle is changed in the form of changing the length of the arcuate axial center line in the axial direction intermediate portion, even when the bending angle is increased, the bending radius of the piping can be maintained as it is, Inconveniences such as breakage of piping caused by bending to a small bending radius and a decrease in service life can be reliably prevented.

It is in the point comprised from the connection means connected by.

  According to the above configuration, since both base members are attached to the surface to be mounted in a relative posture that reveals the piping covering posture that becomes the target bending angle, the two can be kept in a state where they are not separated by the connecting means. Accordingly, it is possible to facilitate the mounting operation of the base members on the mounting surface.

According to a third characteristic configuration of the present invention, the connecting means is provided along one of the one end side of the base member of the inner half body and the one end side of the base member of the outer half body along its axial line or a line parallel thereto. Extending slide guide holes,
Consists of a convex portion formed in a state of entering the slide guide hole in the mounting posture on the other end side of the base member of the inner half body and the other end side of the base member of the outer half body,
At the front end side of the convex portion, the base end side is inserted into the slide guide hole, and protrudes outward from the groove width of the slide guide hole on the front side of the slide guide hole to prevent the slide guide hole from coming off. An enlarged head for preventing slipping is formed.

  According to the above configuration, the slide movement of both base members can be guided by the engagement between the slide guide hole and the base end side of the convex portion, and the slide guide hole and the convex portion can be guided while having a simple structure. Both base members can be coupled by the action of preventing the expansion head from coming off.

According to a fourth characteristic configuration of the present invention, the inner width dimension on one end side of the base member of the outer half body is configured to be the same width or substantially the same width as the outer width dimension on one end side of the base member of the inner half body,

The expansion hole portion for use is formed in a state of being displaced from the expansion head in the mounting posture.

  That is, according to the above configuration, if the base member of the inner half body or the base member of the outer half body or both the base members are not elastically deformed, the both bases are allowed to pass through the enlarged head portion through the enlarged hole portion. Since the connection of the members cannot be released, for example, the problem that the connection of both the base members is unexpectedly released during the slide movement operation of both the base members is efficiently suppressed by using the structure of both the base members. can do.

  According to a fifth characteristic configuration of the present invention, when the base member of the inner half and the base member of the outer half are in a predetermined relative posture by the sliding operation in the engaged state by the engaging means, A positioning means for providing a posture holding force with respect to the relative posture is provided.
