BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering an opening and closing portion of a door provided with electrical equipment.

[0002]

2. Description of the Related Art A door arranged at one end of a support such as a wall with one end connected by a connecting tool such as a hinge,
It is provided so as to be rotatable with respect to the support.
When wiring an electric device such as an electric lock installed on the door, the electric wiring provided inside the support is laid between the support and the door, and the electric wiring is connected to the door. The inside is inserted and connected to the electric device. At this time, in order to enable the electric wiring to follow the opening and closing of the door, the support and the door have a degree of freedom in length.

FIG. 3 is a schematic view showing an electric wiring 33 between the support 32 and the door 31 in a state where the door 31 is opened.
As shown in FIG. 3, when the door 31 is open, the door 3
Since the support end surface 34 and the door end surface 35 are separated by the rotation of 1, the bending of the electric wiring 33 between the door 31 and the support 32 is reduced. On the other hand, the door 31
Is closed, the support end face 34 and the door end face 35
, The deflection of the electric wiring 33 becomes the largest.

[0004]

However, as described above, in the conventional configuration, when the door is open, the end surface of the support is separated from the end surface of the door by the rotation of the door. In, the electric wiring is exposed to the outside. For this reason, there is a problem in that the appearance is impaired. Therefore, a door structure including a cover that covers the exposed portion has been proposed. However, when this door structure is applied to a door to which wiring has already been applied, it is necessary to remove the door and attach a cover to the door and the support, and there is a problem that the installation work becomes large.

Accordingly, an object of the present invention is to provide a cover that can be attached to a door opening / closing section where electric wiring is already installed.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an electric wiring which is formed of a telescopic tubular body and is installed between a door and a support to which one end of the door is connected. With one end of the tubular body penetrated through the inside of the tubular body, one open end of the tubular body is fixed to the erection end of the electric wiring in the door, and the other open end of the tubular body is A cover fixed to a bridging end of the electric wiring in the body, wherein a single cut is provided from one open end to the other open end of the tubular body. The cuts are provided to accommodate the electrical wiring in the erected state when the cover is attached.

[0007]

The cover of the door opening / closing portion is provided with a cut from one opening of the tubular body to the other open end thereof so as to accommodate the installed electric wiring in the tubular body. Have been. For this reason, when this cover is attached to the door opening / closing portion in a state where the electric wiring is installed, the electric wiring is opened in a state where the cutout of the cylindrical body is opened and the cutout is penetrated into the inside of the cylindrical body. Then, by fixing the open end of the tubular body having closed this cut to the erection end of the electrical wiring in the door and its support, respectively, the electrical wiring laid on the door opening and closing part is a tubular body, That is, it is covered with a cover. Therefore, the cover is attached later to the door opening / closing section where the electric wiring is installed.

[0008]

1 and 2 are diagrams showing the construction of a cover of a door opening / closing section A according to the present invention. FIG. 1 is a partially cutaway view of a cover with a door 1 opened, and FIG. FIG. 2 is a schematic cross-sectional view showing a closed state of FIG. The cover of the door opening / closing part A according to the present invention includes a rectangular door 1, a support 2 having one end of the door 1 connected by a connector (not shown), and a bridge between the door 1 and the support 2. In the door opening / closing portion A formed of the electrical wiring B, the support body end face 3 which is a connecting portion between the door 1 and the support 2 is formed so as to cover the electrical wiring B (including the entire wiring tool, if any). It is provided between the door end surfaces 4. Examples of the support 2 include a wall and a wall frame incorporated in an opening of the wall. An opening 6 is provided on the support end face 3 and a door end face 4
Is provided with an opening 7, and an electric wiring B is extended from the support 2 to the door 1 through the opening 6 through the opening 7. The electric wiring B provided between the door 1 and the support 2 as described above has some slack (for example, a loop shape) so that it can follow the opening and closing of the door 1.

The cover 5 provided on the door opening / closing section A is attached so as to expand and contract following the opening and closing of the door 1. In this embodiment, a bellows-like tubular body is used as the cover 5 which can be extended and contracted in this way. The cover 5 has at least one cut a on one arbitrary surface from one open end to the other open end.

In the cover having the above configuration, one opening end of the tubular body is fixed to a bridged end of the electrical wire B in the door 1 in a state where the electric wiring B is penetrated inside the tubular body, The other open end is fixed to the bridging end of the electric wiring B on the support 2. Therefore, at the open ends on both sides of the cylindrical body forming the cover 5, the connection sides 8 and 9 for attaching the cover 5 to the door 1 and the support 2 secure the opening of the cylindrical body. Each is provided in a state where it has been done. In the fixed state as described above, a hollow storage portion O that can store a slack portion of the electric wiring B is provided inside the cover 5.

When the cover 5 is attached to the door opening / closing section A, the following is performed. First, the cut line a is opened, and the electric wiring B is housed inside the cylindrical body in a state where the electric wiring B penetrates both sides of the open end of the cylindrical body.
In a state where the electric wiring B is housed, the cut a is closed so that the inside of the tubular body cannot be seen from the cut a. Next, the connection side 8 at one open end of the cover 5 is
Then, the connection edge 9 at the other open end is fixed to the support 2.

In addition to the above mounting method, the following method may be adopted. First, with the gap a closed, the connection side 9 at one open end of the cover 5 is fixed to one of the door 1 and the support 2 (referred to as the support 2) in advance during wiring work. Next, after the electric wiring B is erected between the door 1 and the support 2 so as to pass through the inside of the cover 5, the connection side 8 at the other open end of the cover 5 is fixed to the door 1.

The cover 5 is made of a material which has sufficient durability for opening and closing doors daily and is flame-retardant.

[0014]

As described above, according to the cover of the door opening / closing part according to the present invention, the cut for accommodating the electric wiring installed between the door and its support is formed on one side of the cylindrical body. With the configuration provided from the opening end to the other opening end, it is possible to attach a cover that covers the electric wiring after the electric wiring is installed on the door opening / closing portion. Therefore, it is possible to install a cover that covers the electric wiring without performing a large-scale installation work such as modifying the structure of the door and the support at the door opening / closing section where the electric wiring is already installed.
