Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a metal wire gutter for protecting electric wires wired on a floor or a wall surface, and electric wires for communication.

(Prior Art) Conventionally, this type of gutter was molded with synthetic resin,
Since a harmful gas is generated at the time of fire, a gutter made of metal is required. And, as described in Japanese Utility Model Laid-Open No. 52-85196, for example, a line gutter formed of a conventional synthetic resin has a cross section having a bottom plate and side edges bent from both sides of the bottom plate. From an elongated U-shaped gutter body and a cover having a cover surface and side edges bent from both sides of the cover surface and fitted in the gutter body, the cross-section being substantially U-shaped. On the outer surface of the base of both side edge parts of the gutter body, continuous concave grooves are formed in the length direction, and at the lower ends of both outer edge parts of the cover, the groove grooves on both side edge parts of the gutter body are respectively formed. The structure in which the engaging ridges are formed is adopted.

(Problems to be solved by the device) However, if the wire gutter of the conventional structure described in Japanese Utility Model Laid-Open No. 52-85196 is molded from a metal material as it is, the fitting depth of both side edges of the cover is deep. Since the cover fits while expanding it, the side edges cannot be easily fitted, wiring workability is poor, and strength is maintained if the thickness of the gutter body and the cover are reduced to facilitate fitting. You have a problem that you cannot.

The present invention has been made in view of the above problems, and uses a metal wire gutter body and a metal cover that are safe and do not generate harmful gas during a fire unlike a synthetic resin. Provide a metal wire gutter that enables easy wiring work using the gutter body and a metal cover, and can be cut according to the wiring dimensions without being restricted by the cutting position of the wire gutter body and the cover. The purpose is to

(Means for Solving the Problem) The metal wire gutter of the present invention is a thin wire having a substantially U-shaped cross section formed of metal having a mounting surface portion and side edges bent from both sides of the mounting surface portion. It consists of a gutter body, a cover surface part, and an elongated cover having a substantially U-shaped cross section formed of metal, which has side edges bent from both sides of the cover surface part and is fitted to the wire gutter body. The outer side surfaces of both side edge portions of the gutter body are formed with a locking portion continuous in the longitudinal direction at an intermediate position in the height direction, and the tip ends of the both side edge portions are bent in a direction in which they approach each other. A fitting guide portion of the cover is formed, and engaging portions that engage with locking portions of both side edge portions of the gutter body are formed at intervals on inner surfaces of both side edges of the cover.

(Operation) In the metal wire gutter of the present invention, the wire gutter body is fixed with screws along the wire wiring position on the floor or wall surface, and the wire is placed between the side edges of the wire gutter body. Wire and fit the cover on the gutter body. At this time, the engaging portion is formed at the middle position in the height direction of the side edge portion that is bent from both sides of the gutter body, and even if the depth of the fitting of the cover is deep, the engaging portion of the cover engages with the engaging portion. Since the mating part can be easily engaged, and the tip side of this side edge part is formed with the cover fitting guide part which is bent in the direction toward each other, the electric wire does not come off from both side edge parts, and the wire gutter. There is no risk of damaging the wires by sandwiching them between the body and cover. Guided by this cover guide part, both side edges of the cover are fitted to both side edges of the gutter body, and the engaging part of the cover elastically engages with the locking part of the gutter body to make the cover line. It does not come off from the gutter body. Moreover, since the locking portion of the gutter body is continuous in the length direction, there is no restriction on the cutting position, and the engaging portion of the cover is engaged and held by the locking portion regardless of the cutting position. Furthermore, by forming the engaging portions at intervals, the formation is easy, and even if there is a deviation, the deviation from the locking portion can be absorbed, and the cover can be reliably attached to the gutter body.
