[Embodiment of device]

 Hereinafter, a specific configuration of the vertically movable floor outlet according to the present invention will be described in detail with reference to the illustrated embodiment. 1 is a sectional view showing an embodiment of a vertically movable floor outlet of the present invention, FIG. 2 is a plan view showing an example of a cable protection cylinder, and FIG. 3 is a sectional view taken along line AA of FIG. Is.

In the figure, reference numeral 1 denotes a floor plate in which a flange portion 3 is continuously provided on an upper peripheral edge of a tubular portion 2, and the tubular portion 2 is fitted into a mounting hole formed on a floor surface, and the flange portion 3 is attached thereto. It abuts and locks around the hole. Reference numeral 4 denotes an intermediate cylindrical body having a diameter that allows it to be inserted into the cylindrical portion 2 of the floor plate 1. Reference numeral 5 denotes an outlet attached to the inside of the middle tubular body 4 with its plug receiving surface facing sideways, and 6 denotes a lid fixed to the upper surface of the middle tubular body 4.

Reference numeral 7 denotes a spring receiving body fixed below the tubular portion 2 of the floor plate 1 and in an inward position, and 8 is recessed in the lower portion of the spring receiving body 7 and the middle tubular body 4. It is a coil spring elastically mounted between the spring receiving groove 9. Since the lower side of the coil spring 8 is fixed to the spring receiving body 7, the urging force of the coil spring 8 is directed to the upper side, and the middle tubular body 4 equipped with the outlet 5 is It is designed to project to the upper surface of the floor plate 1 by the elastic force of.

The middle tubular body 4 protruding from the upper surface of the floor plate 1 can be stored in the tubular portion 2 by pushing it into the tubular portion 2 of the floor plate 1 against the elastic force of the coil spring 8. It is like this. It should be noted that a locking mechanism is attached to the tubular portion 2 and the intermediate tubular body 4 so that the state in which the intermediate tubular body 4 is stored in the tubular portion 2 is maintained, and the central tubular body 2 projects from the upper surface of the floor plate 1. A locking mechanism is provided so that the tubular body 4 can maintain the protruding state, that is, it is not pushed down unexpectedly even when a downward load is applied to the middle tubular body 4, but this locking mechanism itself has been publicly known. Therefore, the illustration is omitted.

Next, reference numeral 10 in the drawing denotes a cable protection cylinder attached inside the cylindrical portion 2 of the floor plate 1 and at a position inside the winding formed by the coil spring 8. In the case of the illustrated embodiment, the cable protection cylinder 10 is formed by slidably fitting cylindrical bodies 11A, 11B and 11C having three stages with different diameters. Depending on the lengths of the tubular portion 2 and the middle tubular body 4, the number of steps may be two or four. It should be noted that the tubular bodies 11A, 11B, and 11C are fitted to the tubular bodies 11A, 11B, and 11C easily, and in order to provide a flexible state against an unexpected load applied in the radial direction during use, the tubular bodies 11A, 11B, and 11C have A vertical slit 17 is formed as shown in FIG.

The cable protection tubular body 10 extends along with the rise of the intermediate tubular body 4 due to the elastic force of the coil spring 8, and the intermediate tubular body 4 is placed in the tubular portion 2 of the floor plate 1. It is designed to shrink when stored. Therefore, in the illustrated embodiment, the flange portion 12 projecting from the lower end of the lowermost cylindrical body 11C is press-fitted into the groove 13 formed in the inner peripheral portion of the lower end of the spring receiving body 7, and the uppermost cylinder is The flange portion 14 extending to the upper end of the cylindrical body 11A is brought into contact with the upper surface of the step portion 15 formed inside the middle tubular body 4, so that the cable protection tubular body 10 moves up and down the middle tubular body 4. It expands and contracts in response to.

The vertically movable floor outlet of the present invention has the above-mentioned configuration, and the cable protection cylinder 10 has a large diameter when the middle cylinder 4 is stored in the cylindrical portion 2 of the floor plate 1. The medium-diameter tubular body 11B is housed in the tubular body 11A, and the small-diameter tubular body 11C is housed in the tubular body 11B, so that the tubular body 11B is contracted as a whole.

When the outlet 5 is used, a coin-like object is inserted in the narrow groove formed on the upper surface of the lid body 6 and the inner cylindrical body 4 is rotated in a predetermined direction. The locking mechanism is released and the middle cylinder body 4 instantly projects upward by the elastic force of the coil spring 8. At this time, in the cable protection cylinder 10, the flange portion 14 protruding from the uppermost cylindrical body 11A is brought into contact with the upper surface of the step portion 15 formed inside the middle cylindrical body 4, so that The cylinder body 4 is instantly expanded according to the ascending motion (FIG. 1).

Further, when the use of the outlet 5 is stopped and the inner cylindrical body 4 is stored, the lid 6 is rotated in a predetermined direction to release the locked state, and then the elastic force of the coil spring 8 is resisted. While the middle tubular body 4 is pushed down, the tubular bodies 11A, 11B, 11C of the cable protection tubular body 10 also contract accordingly. Therefore, the extra length of the cable 16 is not blocked by the cable protection cylinder 10 and is not sandwiched between the windings of the coil spring 8.
