Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter case for accommodating a motor-driven shutter body for winding and feeding a slat by an electric motor.

[0002]

2. Description of the Related Art Conventionally, shutters have been used to cover openings such as windows provided in buildings. As such a shutter, there is an electric shutter in which a slat is wound and fed by an electric motor as disclosed in Japanese Patent Application Laid-Open No. 8-199944. The shutter is provided with a shutter case for housing a shutter body including the above-mentioned slats, electric motors and the like.
Then, the shutter body is attached to the building while being housed in the shutter case. At this time, an electric wire for supplying electric power to the electric motor is connected to the electric motor, and the electric wire extends from the building side. Thereby, electric power is supplied to the electric motor from inside the building, and the slat can be automatically opened and closed by the electric motor.

[0003]

In mounting such a shutter on a building, an electric wire is connected to a motor of the shutter, and then the shutter is mounted. Here, a certain distance is required between the building and the shutter in order to perform the connection work of the electric wires, and accordingly, the electric wires also become longer. As a result, when the slat is wound up, the electric wire may interfere with the slat or the like and be entangled with the slat, and the shutter body may malfunction. For this reason, in order to prevent the wires from interfering with the slats, etc., move the wires to a position that does not interfere with the slats, such as corners inside the shutter case, with a slight gap between the building and the shutter case. After that, it is necessary to perform the mounting work of the shutter, and thus there is a problem that the mounting work of the shutter becomes troublesome.

[0004] It is an object of the present invention to provide a shutter case that facilitates the mounting operation.

[0005]

Referring to the drawings, the present invention relates to a shutter case 32 for accommodating an electric shutter body 31 for winding and feeding a slat 31A by an electric motor 31B. A partition member (for example, a partition plate 34) is provided to partition a space for accommodating an electric wire 33A for supplying electric power to the electric motor 31B and a space for accommodating the shutter main body 31. In the present invention, by providing the partition member, the electric wire does not interfere with the slats or the like, and the winding of the electric wire is prevented. For this reason, after connecting the electric wires, when attaching the shutter to the building, close the shutter to the building, with a slight gap left between the shutter case and the building, even if the electric wire is pushed into the inside of the shutter case casually Therefore, the electric wire is not caught. Thereby, the work of mounting the shutter can be easily performed.

[0006] In the above, it is preferable that the partition member (for example, the partition plate 34) is provided on the back side of the shutter case 32 and is provided so as to be recessed inward from the back side edge of the shutter case 32. By doing so, between the partition member and the back edge of the shutter case,
A sufficient space for accommodating the electric wires is ensured, and even if the accommodating space for the electric wires is ensured, it is not necessary to largely change the internal structure of the shutter case. For this reason, even if a partition member for preventing the electric wire from being caught is provided,
The manufacturing cost of the shutter does not increase significantly.

A partition member (for example, a partition plate 34)
It is preferable that the wire extends over a wider range than the reach of the electric wires 41 and 42. In this way, even when the wires are lengthened to facilitate the work of connecting the wires when attaching the shutter case, the partition member does not completely contact the shutter body and the wire is reliably prevented from getting caught. Therefore, the work of mounting the shutter is further facilitated.

Further, a partition member (for example, a partition plate 34)
Is preferably provided with a hooking member 34C for hooking the electric wires 41, 42. With this configuration, when the shutter is mounted, the electric wire is hung on the hook member, and the electric wire does not drip and does not protrude outside the shutter case. Therefore, even if the electric wire is long, the shutter mounting operation is easy. Will be able to do it.

At the ends of the electric wires 33A and 33B, one of connectors (for example, concave connectors 36 and 37) which are fitted into and recessed from each other is provided, and one of the connectors is connected to the electric wires 24A and 24B extending from the building side. It is preferable that electric power can be supplied to the electric motor 31B by fitting the other connector (for example, the convex connectors 26 and 27) provided at the end of the motor 31B. In this way, since the connection of the electric wire only needs to be made by mating one side of the connector with the other, the connection work can be performed in a short time, thereby shortening the time for mounting the shutter. It is possible to do.

24B and the electric wires 33A and 33B are connected to each other. Thereafter, when the shutter 30 is moved closer to the building unit 3A, the electric wires 41 and 42 are loosened as shown in FIG. 6B. Further, the shutter 30 is connected to the building unit 3A.
6C, a small gap is left between the shutter case 32 and the building unit 3A as shown in FIG. 6C. In this state, the electric wires 41 and 42 are connected inside the shutter case 32. It is folded in two on the hook member 34C and hooked. Subsequently, as shown in FIG. 6 (D), the shutter case 32 is brought into close contact with the ceiling beam 21B of the building unit 3A and attached to the same beam 21B, and the operation of attaching the shutter 30 is completed.

According to this embodiment, the following effects can be obtained. That is, since the partition plate 34 is provided on the shutter case 32, even if the electric wires 41 and 42 are pushed into the shutter case 32 casually from a slight gap formed between the building unit 3A and the shutter case 32. The wires 41 and 42 do not interfere with the slats 31A and the like, and the wires 41 and 42 do not get caught. Thereby, the work of mounting the shutter 30 can be easily performed.

The partition plate 34 is connected to the shutter case 3
2 is provided on the back side of the inside so as to retreat inside the back side edge of the shutter case 32, so that there is enough space between the partition plate 34 and the back side edge of the shutter case 32 to store the electric wires 41 and 42. Space can be secured and electric wires 41 and 4
Even if the storage space of 2 is secured, the shutter case 32
There is no need for major changes in the internal structure. For this reason, even if the partition plate 34 for preventing the electric wires 41 and 42 from being involved is provided, the manufacturing cost of the shutter 30 does not significantly increase.

Further, since the hook 34C for hooking the electric wires 41 and 42 is formed on the partition plate 34, the shutter 30
When the shutter 30 is mounted on the building unit 3A, the wires 41, 42 do not hang down and protrude outside the shutter case 32 when the shutter 30 is mounted on the building unit 3A. , 42 can be easily installed even when the shutter 30 is long.

The electric wires 24A, 24B and the electric wire 33
A and 33B are connected by a connector connection in which one side and the other side of the connector are mated with each other, so that the connection work between the electric wires 24A and 24B and the electric wires 33A and 33B can be performed in a short time. It is possible to reduce the time required for the mounting work of the 30.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and also includes the following modifications.
For example, the shutter 30 is not limited to being installed on the building unit 3A provided on the first floor of the unit building 1, and may be installed on the building unit 3B provided on the second floor. At this time, as shown in FIG. 7, if the shutter 30 is arranged behind the eaves ceiling of the roof 5, the appearance of the unit-type building 1 is not impaired.

The method of connecting the electric wires is not limited to the case where the electric wires extending from the building side and the electric wires extending from the shutter side are connected by a connector or the like. A connecting terminal is formed on the shutter, and the connecting terminal is formed on the connecting terminal. An electric wire extending from the building side may be connected, or a connection terminal may be formed on the building side, and an electric wire extending from the shutter side may be connected to this connection terminal.

Further, as the partition plate 34, the locking member 3
4C may be omitted. However, if the locking member 34C is provided as in the above-described embodiment, the wires 41 and 42 are locked by the locking member 34C when the shutter 30 is mounted. It is preferable that the shutters 30 can be easily mounted even if the wires 41 and 42 are long, because the wires 41 and 42 do not hang down and protrude outside the shutter case 32.

Further, the partition plate 34 is not limited to the one having the length A for closing the entire opening formed on the back side of the shutter case 32, and may be a half of the above embodiment as shown in FIG. May have a length dimension A / 2. Here, assuming that the length of the wires 41 and 42 outside the partition plate 34 is L, the reachable range of the folded wires 41 and 42 is L / 2 from the base of the wires 41 and 42. ing. The length A / 2 of the partition plate 34 is larger than L / 2. That is, the size of the partition plate may be set according to the storage state of the electric wires 41 and 42, and may be wider than a reachable range of the electric wires 41 and 42. In other words, if the electric wire is folded three times or more, a smaller partition plate can be adopted. In short, the space for storing the electric wires and the space for storing the shutter main body may be separated so that the electric wires are not caught in the slats or the like, and the size of the partition plate 34 may be appropriately determined in implementation. However, as in the above embodiment, the length dimension of the partition plate 34 is
The length A is larger than the length L of the wires 41 and 42 outside the wire 4 and the wire 41 and 42 is extended to a wider range than the reachable range of the wires 41 and 42 even if the wires 41 and 42 are extended. This is preferable in that the wires 41 and 42 do not completely contact the shutter body 31.

The partition member is not limited to a plate-like partition plate, but may be a mesh-like partition plate.

Further, the building is not limited to the unit-type building 1 in which a plurality of box-shaped building units are combined, but also a panel-type prefabricated house in which a plurality of plate-shaped wall panels and floor panels are combined. It may be a general building made of a conventional method of joining columns, beams and beams at a construction site.
