  However, the conventional wiring duct is used by cutting the wiring duct body to a desired length in advance when it is disposed along the ceiling surface, for example, the installation surface. In the corner portion, if the gap occurs at the end portion on the end cap side of the wiring duct and the corner portion of the ceiling surface, the design property is deteriorated because the gap cannot be filled. there were.

  Therefore, it is necessary to adjust the length strictly at the time of cutting the wiring duct body, and there is a possibility that the workability becomes complicated.

  The present invention has been made in view of the above points. When the wiring duct is disposed on the installation surface, the length of the wiring duct can be finely adjusted at the end in the longitudinal direction, and the fine adjustment is performed. An object of the present invention is to provide a wiring duct end adjusting member and a wiring duct that can be easily operated.

The wiring duct end adjusting member according to claim 1 includes an insertion coupling portion to be inserted into an opening at a longitudinal end portion of the wiring duct main body; a rectangular bottom portion, and a pair of side walls rising from both side portions in the longitudinal direction of the bottom portion preparative integrally includes said with outer surface bottom portion and by said pair of side walls is formed into a flat U-shaped cross section, the insertion coupling portion is disposed on the end of one side in the longitudinal direction, the other A main body provided with an opening at an end; and a closing plate that slides into and locks the opening of the main body and closes the opening; A wiring duct end adjusting member which is inserted and coupled to the opening of the longitudinal end of the wiring duct body so that the shape-shaped opening faces the installation surface side of the wiring duct body, the inner bottom surface of the body portion, Tokoro over the short direction A plurality of grooves formed at an interval, a pair of the inner surface of the side wall of the body portion is formed such that a plurality of recesses formed at the same interval and at least the predetermined distance, away from the particular interval as said recess A plurality of convex portions for guiding the closed plate, and the main body portion can be adjusted in length by being cut at any concave portion of the plurality of concave portions of the pair of side walls. It is characterized by that.

  In the present invention and each of the following inventions, each configuration is as follows unless otherwise specified.

  “At least the plurality of recesses formed at the same interval as the predetermined interval” means that the groove and the recess at the bottom of the main body are formed at substantially the same position, but deviation due to manufacturing errors is allowed. Is.

  According to the present invention, for example, when it is desired to arrange the end portion of the wiring duct at the corner of the ceiling surface that is the installation surface, first, the wiring duct body that is the main component of the wiring duct is first cut to a desired length. And it installs in the ceiling which is an installation surface in the state assumed that the feed-in box was attached to the one end side edge part in the longitudinal direction of the said wiring duct main body. At this time, if a relatively large gap is generated between the end of the wiring duct body opposite to the feed-in box and the corner of the ceiling, the gap is measured in advance.

  Next, the wiring duct main body is once removed from the ceiling, and the length of the end on the side opposite to the feed-in box side is adjusted using the wiring duct end adjusting member of the present invention.

That is, a plurality of grooves are formed at predetermined intervals on the bottom of the wiring duct end adjusting member. Therefore, it can be seen from the measurement result of the gap that the gap can be substantially filled with the wiring duct body disposed on the ceiling by cutting at which position of the plurality of grooves. Therefore, the bottom of the main body is made visible, and the location of the groove to be cut is specified among the plurality of bottom grooves.

  The protruding pieces provided on both sides of the closing plate are provided so that the width between the protruding pieces on the side opposite to the bottom side is larger than the width between the protruding pieces on the bottom side. It is preferable that the length between them is formed to be larger than the width between the recesses of the main body. This is because, if formed in this way, the closing plate can be easily locked by being press-fitted into the main body.

  According to the present invention, since the concave groove of the closing plate is guided by the convex portion of the main body portion, the closing plate is attached to the opening portion of the main body portion. It is press-fitted between the recesses.

According to the wiring duct according to claim 4, the wiring duct main body; the wiring duct end adjusting member according to any one of claims 1 to 3 provided at one end of the wiring duct main body in the longitudinal direction; A feed-in box provided at an end portion on the other side in the longitudinal direction of the wiring duct main body. According to the present invention, the present invention has the same operation as that of any one of the first to third aspects .

  According to the first aspect of the present invention, when the wiring duct is disposed on the installation surface, the length of the wiring duct can be finely adjusted by using the wiring duct end adjusting member at the end in the longitudinal direction. Therefore, the gap between the wiring duct and the installation surface can be substantially eliminated. Therefore, it is possible to provide a wiring duct that is excellent in design.

  In addition, the fine adjustment of the length of the wiring duct can be easily confirmed by using the groove at the bottom of the wiring duct end adjusting member and the concave portion of the side wall, so that the length adjustment work is not complicated. .

  According to the second aspect of the present invention, the installation operator of the wiring duct main body does not measure the cutting dimension of the main body again by using the dimension display portion of the wiring duct end adjusting member as a guide. Furthermore, in addition to the dimension display part, the guideline for dimension adjustment finer than the predetermined interval can be easily performed by the concave portion of the side wall, so that fine dimension adjustment can be easily realized.
