DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long object which is attached to a duct having an open surface, and which supports a long object such as an electric wire accommodated in the duct in a longitudinal direction so as not to fall outside through the opening of the duct. Regarding support.

[0002]

2. Description of the Related Art In a building such as a building or a factory, as a method of mounting a large number of lighting fixtures at appropriate intervals, a duct or a raceway (hereinafter, collectively referred to as a duct) made of a channel steel has an opening. It is suspended downward from an upper structure such as a ceiling or a beam with hanging bolts or the like, and a plurality of lighting fixtures (for example, fluorescent lamps) are attached to the opening on the lower surface of the duct along the longitudinal direction of the duct to provide lighting. The electric wires connected to the equipment are housed in a duct, wired along the duct, and a lid is attached to the lower surface of the duct.

[0003] However, even if an attempt is made to place the electric wire in the duct with the opening of the duct facing downward and wire the wire, the wire hangs down from the opening and cannot be accommodated in the duct. For this reason, conventionally, as shown in FIG.
Was not allowed to hang down from the opening 3 on the lower side of the duct 2.

However, winding the vinyl tape 1 around the outer periphery of the duct 2 is troublesome, and the vinyl tape 1 must be removed before the lid 5 is attached to the opening side of the duct 2, which is extremely troublesome. It was hanging.

For this reason, conventionally, a plastic support 5 having two semicircular curved portions 5a and 5b as shown in FIG. 16 is previously provided in the duct 2 at appropriate intervals as shown in FIG. And the electric wire 4 is connected to the two curved portions 5.
The wires 4 are supported by being inserted in the direction of the arrow between the curved portions 5a and 5b while elastically deforming the open end portions 5a 'and 5b' of the a and 5b inward and housed inside the two curved portions 5a and 5b. It has also been suggested.

[0006]

However, FIG.
In the wire support 5 shown in FIGS. 6 and 17, the curved portions 5a and 5b are easily deformed so that the wire 4 can be easily pushed in, and the open ends 5a 'and 5b' of the curved portions 5a and 5b are directly supported by the duct 2. When the duct 2 is wide and the number of electric wires 4 to be stored is large, the strength of the support 5 is insufficient and the bent portions 5a and 5b
However, there was an inconvenience that it was deformed downward and sagged.

In addition, since the support 5 has a structure in which the electric wire 4 is housed inside the curved portions 5a and 5b, there is also a disadvantage that it is not possible to additionally mount the support 5 between two adjacent supports after wiring. .

An object of the present invention is to provide a long object support for holding a long object such as an electric wire, which solves these problems, so as not to fall out of a duct.

[0009]

In order to achieve the above-mentioned object, a first aspect of the present invention comprises a bottom plate, both side plates, and first and second lip portions projecting from the both side plates. A long object support attached to a duct having an opening between both lip portions and supporting a long object housed in the duct, wherein a contact portion on a distal end side inside the duct is provided. The first lip portion abuts on the first lip portion and the base portion abuts on the other second lip portion while the base portion abuts on the other second lip portion, and is accommodated in the duct in the longitudinal direction. A horizontal portion that prevents the long object from dropping out of the opening to the outside, and is integrally protruded from a base of the horizontal portion, and a tip portion abuts against the bottom plate of the duct and the bottom plate. An arm portion held between the second lip portions in an elastically deformed state, and a long object accommodated in a duct is placed in the horizontal direction. It is adapted to support in parts.

[0010] Because of this, the arm of the long object support is inserted through the opening of the duct 1 so that the distal end of the arm contacts the inner surface of the bottom plate of the duct, and the arm is elastically deformed and the horizontal portion is extended. The base of the abutment against the second lip of the duct, and the arm is clamped between the bottom plate of the duct and the second lip. The part is suspended between the first and second lip parts, and the long object is pressed against the contact part at the tip of the transverse part to push up the leading end of the transverse part to put the long object inside. When the long object is pushed into the duct, the long object is held by the horizontal portion between the first and second lip portions so as not to fall outside from the opening of the duct. Further, even when the long object is already stored in the duct, the arm member can be inserted between the long object and the side plate on the second lip portion side, and the long object support can be similarly attached to the duct.

According to the second aspect of the present invention, since the base portion of the horizontal portion is provided with an engaging portion that engages with the bent portion of the second lip portion of the duct, the mounting in the duct is easy. More sure.

According to a third aspect of the present invention, a step is provided at the abutting portion at the tip of the horizontal portion to abut on the bent portion of the first lip portion of the duct. Mounting becomes more reliable.

According to a fourth aspect of the present invention, since the wide portion is provided at the end of the horizontal portion, the long object is brought into contact with the bottom plate of the duct when the long object is pulled in a state of being stored in the duct. Because of the wide portion, the long object support is prevented from falling.
