2. Description of the Related Art In recent years, in addition to conventional electric appliances, the use of office automation equipment has increased in general households, and the wiring has been complicated, resulting in octopus wiring, which can be caught or broken during walking. There is a problem. Therefore, in order to solve these problems, a technique for housing the wiring under the floor has been proposed. For example, JP-A-9-125660 and JP-A-1-125660 have been proposed.
-283012, JP-A-8-239992 and the like describe various underfloor wiring structures. However, in each of these prior arts, there is a problem in that the work of providing a wiring path under the floor is complicated, and that it takes time and effort to cope with the increase in the number of wirings later.

[0003]

Further, as a known technique, as shown in the side sectional view of FIG. 4 of the present application, the floor receiving portion 11 of the floor supporting leg 1 and the floor material arranged on the foundation floor F. A technique is known in which a wiring duct 6 is provided between the wirings 5, the wiring 3 is housed in the wiring duct 6, and a wiring path is provided under the floor. However, in this method, since the floor material 5 is supported via the wiring duct 6, the work becomes complicated, and when the wiring duct 6 is added in order to cope with the increase in the wiring later, the height of the floor support leg 1 is increased. Since it is necessary to readjust and lay it, it takes a lot of work for construction. The present invention solves the above-mentioned problems, and it is possible to provide a wiring path under the floor by a simple operation, and even if a wiring duct is added later, an underfloor wiring pit that can be constructed with good workability is provided. The task is to provide.

[0004]

The present invention has been conceived to solve the above problems, and according to the present invention, a floor support leg for supporting a floor material and a wiring storage for storing wiring. And a top part of the floor support leg is a floor receiving part having a substantially rectangular shape in plan view, and a fixing part for fixing the wiring storing part is provided on a lower surface of the floor receiving part. An underfloor wiring pit is provided, which is continuously provided and has a locking piece for suspending and extending the wiring accommodating portion, which extends substantially at the center of four sides of the fixing portion. It

Although there is no particular limitation on the wiring housing portion, it is usually used as a wiring duct C.
Mold channels are preferably used. Moreover, you may provide the protrusion part for fixing a floor material in the four corners of the upper surface of a floor receiving part.
By inserting these protrusions into the insertion holes formed in the back surface of the floor material, the floor material and the floor receiving portion can be firmly fixed. Further, by using a plurality of the floor support legs and bridging the long wiring storage portions over them, the underfloor wiring pits can be linearly arranged. Alternatively, a plurality of floor supporting legs may be used to arrange long wiring accommodating portions vertically and horizontally, and the underfloor wiring pits may be arranged at a right angle.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will now be described in more detail with reference to the drawings. Figure 1
FIG. 3 is a perspective view showing a floor support leg 1 used in the underfloor wiring pit of the present invention. In FIG. 1, the floor support leg 1 arranged on the foundation floor F has a floor receiving portion 11 at its upper portion, and the wiring receiving portion 2 (see FIG. 2) is provided on the lower surface of the floor receiving portion 11.
The fixing portion 12 for fixing the is continuously provided. Fixed part 12
Is a hanging piece 121 which is formed by suspending and extending substantially the center of its four sides, and bending the end portion thereof at a substantially right angle to form a locking piece 121. The tip of the locking piece 121 is bent further upward, and wiring is stored. Part 2
It has a structure that locks.

FIG. 2A is a side sectional view taken along the line AA of FIG. 1, in which the wiring accommodating portion 2 is locked to the locking piece 121.
The state where it is fixed and the wiring 3 is housed is shown. In the present embodiment, a C-type channel is used as the wiring housing section 2. FIG. 2B is a side sectional view showing a state where the floor material 5 is placed on the floor receiving portion 11. In FIG. 2B, the floor material fixing protrusion 4 is inserted into an insertion hole 51 formed in the lower surface of the floor material 5 and plays a role of fixing the floor material 5 to the floor receiving portion 11.

FIG. 3 shows a state in which a long wiring accommodating portion 2 is bridged by using a plurality of floor supporting legs 1 configured as described above. As can be seen from FIG. 3, if the underfloor wiring pit of the present invention is used, it can be used as a conventional wiring duct such as a C-shaped channel in the locking piece 121 of the fixing portion 12 which is a component of the floor supporting leg 1 at a construction site. A wiring path can be provided under the floor simply by engaging and fixing the wiring storage portion 2 which is provided. Although the wiring pits are linearly provided in FIG. 3, the fixed portion 1 provided on the four sides of the floor receiving portion 11
By selecting and using 2, it is possible to bend not only the straight line shape but also the C-shaped channel at a right angle and bridge it, and it is possible to wire vertically and horizontally under the floor.

[0009]

As described above, the present invention is a wiring pit composed of a floor supporting leg for supporting a floor material and a wiring accommodating portion for accommodating wiring, the upper part of the floor supporting leg being substantially in plan view. A rectangular floor receiving portion is provided, and a fixing portion for fixing the wiring receiving portion is continuously provided on the lower surface of the floor receiving portion, and the wiring receiving portion is provided at substantially the center of four sides of the fixing portion. An underfloor wiring pit is characterized in that a locking piece for locking is extended downwardly. By configuring in this way,
A wiring path can be provided under the floor with a simple work, and even if a wiring duct is added later, workability can be improved.

Further, by using a plurality of the floor support legs and arranging a long wiring storage portion on them, the underfloor wiring pit can be linearly arranged. It is also possible to extend a long wiring storage section vertically and horizontally over the plurality of floor support legs and to arrange the underfloor wiring pits at a right angle. As described above, according to the underfloor wiring pit of the present invention, a simple method of providing a fixing portion for fixing the wiring storage portion to the floor support leg that supports the floor material can be performed easily without performing a large-scale work. It is possible to vertically and horizontally provide wiring paths under the floor, and it is possible to cope with an increase in wiring later by a simple work.
