In such a configuration, in a stored state, a portion below the top plate portion 5 of the movable body 4 is stored in the storage box 13. Further, in this storage state, the lower surface of the top plate portion 5 and the portion around the opening 11 in the floor plate 3 overlap each other, and when the top plate portion 5 is pushed downward, the top plate portion 5 The lower surface and the floor plate 3 are engaged with each other so that the movable body 4 does not sink below.

  As shown in FIGS. 4 to 6, the movable body 4 includes a frame 20, connector blocks 15 (15 a and 15 b), and a fixing member 24. In the movable body 4, the hinge portion 7 is connected to the frame 20, so that the movable body 4 is rotatably supported by the floor plate 3 via the hinge portion 7.

  The frame 20 includes a substantially rectangular top plate portion 5. The top plate portion 5 functions as a lid portion of the opening portion 11 of the floor plate 3 in the stored state. In addition, the top plate part 5 is good also as another shape (for example, disk shape etc.).

  A frame portion 21 is erected on the back surface of the front portion of the top plate portion 5. The frame portion 21 is opened downward, and the plurality of connector blocks 15 are fitted in the frame portion 21 side by side. The frame portion 21 allows the connector block 15 to be attached and detached from below. As the connector block 15, in addition to the power connector block 15a and the telephone connector block 15b shown in the figure, various types such as a LAN connector block and a dummy block as a simple spacer on which no connector is formed are prepared. Accordingly, it can be appropriately selected and fitted, and the arrangement can be changed as appropriate. Note that the front surfaces (plug fastening surfaces) 15a of the plurality of connector blocks 15 that are fitted in form a series of flat surfaces.

  Further, a pair of left and right side plate portions 22 are erected on the back surface of the side portion of the top plate portion 5 so as to cover and conceal the side surfaces of the connector block 15 fitted into the frame portion 21. And the rib 23 is constructed by the rear part and lower part of these pair of side-plate parts 22. FIG. These side plate portions 22 are integrated with the frame portion 21.

  The fixing member 24 presses the connector block 15 fitted in the frame portion 21 from below, and is detachably mounted on the lower end portion of the frame 20. The connector block 15 is held by the fixing member 24 and the frame portion 21. Specifically, the fixing member 24 includes a substantially columnar base portion 24a disposed adjacent to the lower side of the connector block 15, and a rib 23 extending rearward from both rear and lower corners of the base portion 24a and bent upward. A pair of arm portions 24b extending to the vicinity of the arm portion 24b, and a rib 24c constructed between the pair of arm portions 24b.

  Screw holes 24d are provided on both side surfaces of the base portion 24a, and a pair of left and right screws 25 are inserted through the through holes 22a formed in the lower ends of the side plate portions 22 of the frame 20 from the outside. The fixing member 24 can be attached to the frame 20 by being screwed into the screw hole 24d. In this structure, the heads 25 a of the pair of screws 25 are exposed to the side of the movable body 4. These screws 25 are arranged in a straight line so as to face each other with the head 25a facing outward. The axes of these screws 25 are parallel to the rotational axis of the movable body 4 (the axis of the shaft 8). Further, when the floor plate 3 is mounted on the floor 2, the heads 25 a of these screws 25 are hidden by the floor plate 3 in both the storage state and the protruding state. Specifically, at least a part of the head 25a of the screw 25 is positioned below the upper end of the opening 11 (the surface 3a of the floor plate 3) (FIG. 2). FIG. 2 shows an example in which the entire screw 25 is positioned below the upper end of the opening 11. As a result, the floor plate 3 prevents the driver from engaging the screw 25 from above the floor 2, thereby making it impossible to remove the screw 25.

  Further, stoppers 12 are provided on both side surfaces of the base portion 24a as protrusions protruding outward from the side plate portion 22 through a notch 22b provided at the lower end of the side plate portion 22 of the frame 20. These stoppers 12 are provided closer to the shaft 8 than the screws 25. In this structure, when the movable body 4 protrudes from the opening 11 of the floor plate 3 by the urging force of the torsion spring 9, the stopper 12 engages with the floor plate 3 so that the fixing member 24 has the screw 25. A force in the direction in which the arm portion 24b rotates downward (clockwise direction in FIG. 2) is applied. Therefore, in the present embodiment, a rib 22c as a restricting portion engaged with the rear end portion of the arm portion 24b from the shaft 8 side is formed so as to protrude from the inner surface of each side plate portion 22 of the frame 20. Accordingly, the rotation of the fixing member 24 by the force acting on the fixing member 24 when the stopper 12 is engaged with the floor plate 3 is restricted.

  On the other hand, a terminal block 26 for electrically connecting the connector block 15 and the underfloor wiring 14 is fixed to the back surface of the floor plate 3. In the present embodiment, the terminal block 26 is attached to the floor plate 3 via the bracket 27 at a position behind the connector block 15 in the housed state. Here, in this embodiment, the width of the terminal block 26 is made narrower than the width of the inner walls of the pair of side plate portions 22 of the movable body 4 so that the gaps 28 are formed on both sides of the terminal block 26 in the stored state. It is. By forming the gap 28 in this manner, the underfloor wiring 14 is sandwiched between the fixed terminal block 26 and the rotating side plate portion 22 when the movable body 4 moves from the protruding state to the retracted state. Can be suppressed. The terminal block 26 is electrically connected to any one of the plurality of connector blocks 15 (in this embodiment, the power connector block 15a). By connecting the underfloor wiring 14 to the terminal block 26, the terminal block 26 is connected to the terminal block 26. The connector block 15 (15a) and the underfloor wiring 14 can be electrically connected. It is preferable that the terminal block 26 is connected to a so-called high-power connector block 15 such as the power connector block 15a so as to more easily and surely secure the electrical system having a larger energization power. is there.

  Further, the floor outlet device 1 includes a guide structure that regulates the routing path of the underfloor wiring 14 connected to the connector block 15.

  First, unevenness is formed on the rib 23, and this unevenness is used as a guide structure. In the present embodiment, substantially rectangular notches 23 a are formed at two locations adjacent to the pair of side plate portions 22 as the unevenness. By inserting the underfloor wiring 14 into the notch 23a, it is possible to restrict the wiring of the underfloor wiring 14 from the inside by the wall 23b on the inner side (side away from the side plate portion 22). When the underfloor wiring 14 is routed further inside, the underfloor wiring 14 may overlap with the terminal block 26, other underfloor wiring 14 and the like, which may hinder the movable body 4 from moving from the protruding state to the retracted state. However, such a situation can be suppressed by inserting the underfloor wiring 14 into the notch 23a.

  In the present embodiment, the arm portion 24b of the fixing member 24 is extended to a position facing the notch 23a, and the underfloor wiring 14 inserted through the notch 23a is sandwiched between the rib 23 and the edge 24e of the arm portion 24b. Like to do. Thereby, it can suppress more reliably that the underfloor wiring 14 remove | deviates from the notch 23a, and is wired inside it.

  In the present embodiment, the underfloor wiring 14 is routed in a state of being inserted through an elastic routing tube (for example, a resin tube or a rubber tube) 29 to enhance the protection of the underfloor wiring 14. Further, by holding the underfloor wiring 14 between the rib 23 and the arm portion 24b in a state of being inserted into the routing tube 29, there is an advantage that the stress generated in the underfloor wiring 14 due to the pressing by this holding can be reduced. . In addition, the wiring tube 29 insulates the underfloor wiring 14 particularly when a so-called high-power underfloor wiring 14 such as a power cable and a so-called low-power underfloor wiring 14 such as a LAN cable coexist. Can be made more reliable.

  Furthermore, in this embodiment, the shelf part 30 is formed in the inner wall of the side-plate part 22, and this shelf part 30 is used as a guide structure. In the present embodiment, the side plate portion 22 is bent inward from the rib 23 to the rear end portion and protrudes, and the shelf portion 30 substantially parallel to the top plate portion 5 is separated from the hinge portion 7 (hinge At a position below the portion 7). By doing so, it is possible to suppress the underfloor wiring 14 from being close to the hinge portion 7 and being sandwiched between the floor plate 3 and the movable body 4.

  As shown in FIG. 6, the placement surface 30a of the shelf 30 and the rear edge 23c of the notch 23a are formed at substantially the same position in the vertical direction, and the underfloor wiring 14 inserted through the notch 23a is more reliable. It is preferable that the cable is routed along the shelf 30.

  A method of connecting the underfloor wiring 14 to the connector block 15b (phone connector block 15b in this embodiment) that is not connected to the terminal block 26 in the connector block 15 will be described. When the connector block 15b and the fixing member 24 are attached to the frame 20, the movable body 4 is stored, the screws 25 are removed, the fixing member 24 is removed from the frame 20, and the connector block 15b is attached to the frame portion 21. Remove from the bottom. Of course, this operation is not required when the connector block 15b and the fixing member 24 are not attached to the frame 20 and are not assembled. In this way, the underfloor wiring 14 is connected to the connector block 15b not fitted in the frame portion 21. Then, the connector block 15 b to which the underfloor wiring 14 is connected is fitted into the frame portion 21 from below, and the fixing member 24 is attached to the frame 20 with screws 25. As described above, in this embodiment, when the underfloor wiring 14 is connected to the connector block 15b by fitting the connector block 15b into the frame portion 21 from below, the underfloor wiring 14 is passed through the opening 11 of the floor plate 3. Without being connected to the connector block 15b. Accordingly, the connection work between the underfloor wiring 14 and the connector block 15b can be facilitated as compared with the conventional floor outlet device.

  Further, in the present embodiment, when the floor plate 3 is mounted on the floor 2, the head 25a of the screw 25 is hidden by the floor plate 3 in both the storage state and the protruding state, thereby Even when the floor outlet device 1 is in a protruding state, the screw 25 is difficult to see from above the floor 2, so that the appearance can be improved and the floor plate 3 is attached to the head 25 a of the screw 25. Since the engagement from above is blocked and the screw 25 cannot be removed, the movable body 4 of the floor outlet device 1 installed on the floor 2 is prevented from being disassembled by a user or the like. be able to. Thereby, electric shock and electric leakage due to disassembly of the movable body 4 can be prevented. In this case, the aesthetics can be further improved by positioning the entire screw 25 below the upper end of the opening 11 and hiding the screw 25 by the floor plate 3.

  In this embodiment, a part of the floor plate 3 is located between the stopper 12 and the top plate portion 5. However, such a structure allows the movable body 4 with the fixed member 24 removed to be placed on the floor. This is realized by penetrating the opening 11 of the plate 3 from the upper side and attaching the fixing member 24 to the movable body 4 from the lower side of the floor plate 3. In this case, when the stopper 12 is engaged with the floor plate 3, a force is applied to the fixing member 24 to rotate the fixing member 24 around the screw 25. Since such rotation is regulated by the rib 22c, it is possible to prevent the position of the fixing member 24 from being shifted when the storage state is switched to the protruding state.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made to the above embodiments without departing from the scope of the invention.
