JPH06169514A - Cord cover and wiring protecting method for double floor - Google Patents

Abstract

PURPOSE:To protect cords by providing an opening by cutting a tubelike substance made of flexible material in the longitudinal direction continuously, and covering the cord peripheries at a site where the cord cover is drawn out from under a double floor onto the floor. CONSTITUTION:The figure shows a cord cover 1. And a tube 10 having a bellowslike protrusions and recessions 11 on its periphery is made using an elastomer such as flexible soft plastic or rubber, etc., as raw material. This tube 10 is freely bendable to some extent. An opening 12 is made by cutting the above-mentioned tube 10 in the longitudinal direction from end to end. The cut and torn surfaces 13 are slanted against the surface of the tube, and are made so as to lap over each other. Accordingly, it becomes possible to put cords in the tube by widening the cut and torn parts 13, and comply with the size of the cords to be put in.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord cover and a double floor wiring protection method.

[0002]

2. Description of the Related Art In the case of double-floor wiring, the cord itself is not covered, but the circumference of the wiring take-out hole of the floor board is covered with plastic to protect the wiring. When you want to take out the wiring from a desired place, the floor plate is cut out and the extraction hole is provided to take out the cord, but there is no appropriate method to protect the periphery of the notch, and the cord is attached to the notched steel plate. There was a problem of rubbing and scratching. Further, even when the cord is taken out from the take-out hole whose periphery is protected, there is a case where the cord is stepped on the taken place and the cord is forcibly bent. The present invention aims to overcome these drawbacks.

[0003]

DISCLOSURE OF THE INVENTION According to the present invention, a cord cover in which a tubular material made of a flexible material is continuously slit in the longitudinal direction to form an opening, and a cord cover is pulled out from below the double floor to the floor. So, it is to protect the cord by covering it.

[0004]

By doing so, the cord can be protected wherever it is needed. Also, if a cover with a certain thickness is used, even if a force such as stepping on it is applied, it protects it from being bent at a sharp angle as seen at the base of the plug of electrical equipment.

[0005]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows the cord cover 1. A flexible elastic elastomer such as plastic or rubber is used as a material, and a tube 10 having a bellows-like concavo-convex portion 11 is formed around the tube 10. This tube can be bent to some extent. Such a tube 10 is longitudinally cut end to end to form an opening 12. The cut surface 13 is formed to have a taper obliquely with respect to the surface of the tube so that the cut surfaces overlap each other. If formed in this way, the tear surface can be opened and the cord can be inserted therein, and the thickness of the cord to be inserted can be dealt with. The length of the tube is usually 5 to 20 cm, and the inner diameter is 10 to 10 cm, although not particularly specified.
It is generally 30Φ, and the wall thickness is generally 1 to 3 mm at a thin portion and 3 to 5 mm at a thick portion. If the whole is formed into a thick wall, the cushioning effect is large, but it is difficult to bend. Therefore, if formed into a bellows shape, the cushioning effect is large, and bending to some extent is possible, which is convenient.

When the cord cover 1 is constructed in this way,
As shown in FIG. 2, even when one end of the cord 2 is connected to the electronic device 3 and a large-sized connector 31 is attached to the other end, the cord cover 1 may be covered at any intermediate position. You can In the case where the cord 2 is pulled out from the underfloor 41 of the double floor through the notch 42 of the floor plate 4 onto the floor, it is possible to protect the portion corresponding to the notch 42 with the cord cover 1 as shown in FIG. is there.

In order to make the notch 42 invisible in the cord cover 1, a thin disk-shaped flange 14 is provided at one location around the cord cover 1 as shown in FIG. Good. If a small screw hole is opened in the flange 14, the cord cover 1 can be fixed to the floor surface by using a screw, which is convenient. When the cord 2 pulled out on the floor is to be installed along the floor surface, the cord cover 1 may be provided with a bent portion 15 having a crease, as shown in FIG. By attaching thin holding plates 16 on both sides of the floor, it is possible to fix the cord cover to the floor with screws 17 through the holding plates 16. Furthermore, in order to improve the stain between the cord and the cord cover, it is possible to attach a cushioning cushion sheet 18 to the inner surface of the cord cover 1 as shown in FIG.

[0008]

Since the present invention is constructed as described above, it has the following features. 1 By covering the cord cover, the cord does not rub against the notch of the floor plate and get scratched. 2 By covering the cord cover, the cord will not be bent suddenly and the wiring will not be damaged. Since the cord cover can be covered from the side even at the middle portion of the three cords, the cord cover can be attached at any place even when both ends cannot pass through the holes. The 4 cord cover is torn, and can cope with a certain difference in cord thickness. 5 By placing the cord cover with a bending tendency beforehand,
The code can be easily installed along the floor surface.
