In order to supply electric power from a power supply device on the frame side to an electric device such as an electric lock attached to a door, the energizing metal fitting includes an energizing cable inserted into each of the frame side case and the door side case. However, it is fixed indirectly through a coil spring-shaped protection member for protecting the case or directly at the insertion portion of the case.

That is, since the frame-side case and the door-side case of the current-carrying bracket are integrally connected by the current-carrying cable, if the door-side case is attached to the door in advance, the frame-side case and the current-carrying cable Was hung on the door, and handling until the door was attached to the frame at the construction site was very obstructive and inconvenient.

Therefore, the conventional metal fittings cannot be attached to the door at the door manufacturing factory, and the work of attaching the metal fittings at the construction site must be performed.

The work of attaching the current-carrying metal fittings at the construction site not only results in extremely poor workability, but also a connector for connecting to the electric lock a when manufacturing the door D as shown in FIG. It is necessary to previously wire a predetermined length of an intermediate cable c for energization provided with a connector g for connecting b to an energizing metal fitting at one end at the other end.

[0007]

In this case, the frame-side case d and the door-side case e must be mounted after the door is mounted on the frame. A connector g must be provided to connect the power supply cable f passing through the door-side case e.

In other words, in the conventional energizing bracket, the frame-side case, the door-side case, and the energizing cable are integrated, and the frame-side case and the door-side case can be attached only after the door is attached to the frame. Therefore, there is a problem that the working efficiency is poor as described above, and there is a problem that the number of connecting parts by the connectors is increased, the reliability of energization is reduced, and the cost is increased due to an increase in the number of connectors.

[0009]

The door-side case can be attached to the frame at each of the frame-side cases, and the door-side wiring section provided with the equipment connector for the power supply cable is wired inside the door, and the power supply connector is connected. The provided frame-side wiring portion can be housed in the door-side case or the door, so that there is no need to limit the procedure of the mounting work as in the case of the conventional energizing metal fitting, and the door It can be attached to improve production, not only greatly improves workability,
An object of the present invention is to provide a current-carrying metal fitting that does not require wiring of an intermediate cable having connectors at both ends in a door as in the related art.

[0010]

According to the present invention, there is provided a current-carrying metal fitting comprising: a frame-side case attached to a part of a frame on a door hanging side; and a door-side case attached to a position facing the frame-side case. And an energizing cable that is inserted into the door side case and has an end provided with a device connector for connecting to an electric device and the other end provided with a power connector for connecting to a power cable from a power supply. When the door case is attached to the door, the wiring part of the power supply cable on the device connector side is wired inside the door, and the power supply connector side frame side wiring part inside the door side case or door. When the door is attached to the frame, the frame-side wiring portion of the energizing cable is pulled out from the door-side case or the door, and is inserted into the frame-side case attached to the frame and wired to the frame. It is characterized in that the.

[0011]

Since the frame-side case and the door-side case can be separately mounted at predetermined positions, the door-side case is mounted before the door is mounted on the frame, that is, at a door manufacturing factory, and the power supply cable is connected. The wiring portion on the door side provided with the device connector can be wired in the door, and the wiring portion on the frame side provided with the power supply connector can be stored in the door side case or the door.

Reference numeral 1 denotes a frame-side case which is buried and fixed to a portion of the frame W facing a door-side case, which will be described later, so that an energizing cable, which will be described later, is not cut from the case body 11 and a gap between the frame W and the door D. And a front plate 12 having a bulged hollow guard portion 12a for protecting the power supply cable and a hole 12b for inserting a power supply cable.

Before attaching the door D, the guard portion 12a is temporarily fixed to the case main body 11 by screws or the like in a state where the guard portion 12a is fitted inside the case main body 11.

The reason why the front plate 12 of the frame-side case 1 is temporarily fixed in an upside-down state is that the guard portion 12a which swells when the frame is handled becomes an obstacle until the door is attached to the frame, or the regular door 12 D cannot be installed to prevent dirt or damage during the work until the interior work of the building is completed. This is because there is no recess at the position facing the guard portion 12a, so that opening and closing of the temporary door is not hindered.

The frame-side case 1 may be attached when the door D is attached. However, since the frame-side case 1 is separated from the door-side case and the energizing cable to be described later, it is temporarily attached to the frame W by the above-described method so as not to be lost. It is preferable to fix them.

Reference numeral 2 denotes a door-side case which is buried and fixed at an end of the hanging side of the door D opposite to the frame-side case 1, similarly to the frame-side case 1, and includes a frame-side case body 21 and a front plate. 22

Reference numeral 3 denotes a device connector 31 for connecting to an electric device such as an electric lock R at one end, and a power connector for connecting to a power cable from a power supply device such as a control panel on the door frame side at the other end. A coil spring-shaped protection member 33 made of a steel wire or the like is provided on a portion where the door-side case 2 and the frame-side case 1 are hung. The power supply cable 3 is fixed to the door side case 2 and indirectly passes through the protection member 33.
It is fixed to.

In this embodiment, one end 34 of the protection member 33 is hung on the hanging portion 24 of the door-side case body 21, and then the front plate 22 is attached and fixed to the door-side case 2. However, this fixing method is not limited to the illustrated embodiment, but may be any method.

The protection member 33 prevents the current-carrying cable 3 from bending and breaking each time the door D is opened and closed by using the restoring force of the coil spring. This protective member 33 is not required if it has a restoring force that does not break even if it is broken.

Next, according to the above-described configuration of the present invention, a method of attaching the current-carrying metal fitting of the present invention and a specific usage thereof will be described with respect to the illustrated embodiment.

At the door manufacturing plant, as shown in FIG. 2, the door-side case 2 of the current-carrying fitting is attached to the door D, and the door-side wiring portion provided with the device connector 31 of the current-carrying cable 3 is wired inside the door. The connector 31 faces the notch DR for mounting the electric lock R formed on the door end side, and is temporarily fixed at this location.

At this time, the frame side wiring portion provided with the power supply connector 32 of the power supply cable 3 is housed in the door side case 2 or the door D as shown in FIGS. 3 (a) and 3 (b). .

On the other hand, as shown in FIGS. 4 and 5, the frame side case 1 is temporarily fixed to the frame W at a position corresponding to the door side case 2 attached to the door D.

The frame W is attached before the door is attached to the building, and the temporary door is attached to the frame W until the regular door D shown in FIG. 2 is attached.

When the building or interior work of the building is completed and the regular door D is mounted on the frame W, the temporary fixing of the frame-side case 1 is released, and the front plate 12 is moved so that the guard portion 12a is moved in the direction from which the door D is suspended. After the door D is attached so as to protrude, the frame-side wiring portion provided with the power supply connector 32 of the energizing cable 3 is pulled out from the door D or the door-side case 2 and the guard portion 12a as shown in FIG. Hole 12b and case body 1
1 through the opening 13 on the entire surface and into the frame side case 1,
The power supply connector 32 at the front end is connected to the connector of the power supply cable extending from the control panel on the frame side through the hole 14 provided at the rear end of the frame side case 1, and the device connector 31 at the other end is attached to the door top side. All the operations are completed by connecting to a connector of an electric device such as an electric lock R to be used.

[0028]

According to the present invention, since the frame-side case and the door-side case are separated from each other, the frame-side case and the door-side case are independently mounted on predetermined portions of the frame and the door. be able to.

Also, a door-side wiring portion provided with a connector for connecting to an electric lock of an energizing cable fixed to the door-side case is inserted through the door so as to face the vicinity of the electric lock mounting hole.

Pull out and connect to the power supply device on the frame side, so that the door and the frame are handled integrally like a current-carrying bracket that is integrally connected to the conventional frame side case and door side case, Or, it is not limited to installation at a construction site.

Since there is no restriction on the installation work at the construction site, the door-side case of the current-carrying metal fittings can be pre-installed on the door at the door manufacturing factory, which only significantly improves the workability. There is no need to provide an intermediate cable with connectors at both ends in the door, which was necessary to wire the electric lock to the door at the construction site as in the past. , And the cost can be reduced by reducing the number of connectors.

Further, the door-side case can be attached at the same time as the wiring of the power supply cable when the door is manufactured, and the frame-side case can be attached at any time before and after the door is attached. After the door is mounted, it is only necessary to pull out the current-carrying cable from the door-side case and connect it to the connector of the power cable extending from the control panel through the frame-side case, so that work efficiency can be improved.
