A conventional wiring device that is standardized as an interchangeable wiring device of a large rectangular hub type wiring device is used as the power outlet 31A. A connection frame 32 composed of an artificial resin is used to hold and connect the power outlet 31A to the connection bracket 33.

The connection bracket 33 is formed by subjecting the metal plate to press working. The connecting bracket 33 has a substantially U-shaped shape when viewed from the side. The connection bracket 33 includes a wiring device holding portion 33a having an opening 33b through which the front surface of the power socket 31A can be exposed. The connection frame 32 is connected to the rear side of the wiring device holding section 33a. The wiring device holding section 33a is inclined downward and rearward (to the left in Fig. 5B), so that the plug can be easily inserted into the power socket 31A. The abutting portion 33c which is in contact with the lower surface of the floor material 100 protrudes from the intermediate portion of the upper edge of the wiring device holding portion 33a in one direction (distal from the connecting hole 101 of the floor material 100). The fixing sections 33d and 33e project from opposite ends of the upper edge of the wiring device holding section 33a in the opposite direction (toward the connecting hole 101) with respect to the adjacent section 33c. The bracket connecting member 33f protrudes from the lower edge of the wiring device holding section 33a in the same direction as the abutting section 33c (refer to FIG. 5B), and the wire fixing member 34 is fixed to the bracket connecting member 33f by screws.

The three LAN sockets 31B, which respectively form the size of the unit module, are connected to the connection bracket 33 through the connection frame 32. The second wiring device block 3B has the same structure as the first wiring device block 3A except that the LAN socket 31B is provided as the wiring device. The same elements will be denoted by the same reference symbols and will not be described again.

The partition wall 6 is formed into a substantially U-shape by bending a metal plate. The partition wall 6 includes an intermediate portion 6a having an insertion hole 6b formed in a position corresponding to a screw hole of the fixing portion 33g of the connection bracket 33 of the first and second wiring device blocks 3A and 3B. When the fixing screw 6c is inserted into the insertion hole 6b and screw-fitted to the screw hole of the corresponding fixing portion 33g, the partition wall 6 is fixed to the individual connection bracket 33. The partition member 6 cooperates with the joint bracket 33 to define a space below the floor material 100, thereby forming a storage space for storing wires connected to the first and second wiring device blocks 3A and 3B.

Referring to Fig. 1, for example, the frame member 4 is formed to have a rectangular frame shape by aluminum die casting, and its four sides are substantially equal to each other. The frame member 4 has a rectangular opening 41 formed in a central region of the frame member 4. A support section 42 is formed in the periphery of the opening 41 to project inwardly from three sides (except for one side), wherein a portion of the covering member 5 is placed on the support section 42 immediately after closing the covering member 5. Four insertion holes 43a and 43b are formed in the support section 42 in positions corresponding to the screw holes 29a and 29b of the first and second top plate members 2A and 2B, into which the connection screws 44 are inserted. The covering member 5 is rotatable about an axis of rotation that is parallel to the side of the opening 41 where the periphery of the opening 41 is not formed. A shaft hole 45 that rotatably supports the shaft 51 of the cover member 5 is formed in the periphery of the opening 41 (only one shaft hole is shown in Fig. 1).

The covering member 5 includes a cover 50 which is formed into a rectangular plate shape by, for example, aluminum die casting. The shaft 51 projects from the opposite surface of the cover 50 on one end side. A recess 52 is formed in the edge of the cover 50, and a wire (not shown) connected to the first and second wiring device blocks 3A and 3B can pass through the recess 52, and one of the shafts 51 extends from the edge of the cover 50 Out. A wire access door 53 for opening the recess 52 is rotatably coupled to the cover 50. For example, the wire access door 53 is formed into a horizontally elongated rectangular plate shape by aluminum die casting. As shown in Fig. 12, a plurality of downwardly projecting strut segments 53a (e.g., three strut segments in this embodiment) are formed on the lower surface of the wire access door 53 in spaced relation to each other. Referring again to Fig. 1, a bushing 55 for protecting a wire (not shown) is held between the strut segments 53a which is inserted through the opening of the wire access door 53 and disposed below the floor.

In this regard, each of the strut segments 53a is formed in a triangular shape when viewed from the side, and includes a first side extending in the horizontal direction when the wire access door 53 is opened, and a second extending in the vertical direction when the wire access door 53 is closed. side. The intermediate pillar section 53a serves as a partition wall to isolate a high-current electric wire (for example, a power supply line connected to the power outlet 31A) and a low-current electric wire (for example, a communication line connected to the LAN outlet 31B). For example, if a high current wire is disposed on one side of the intermediate strut segment 53a, and if a low current wire is disposed on the other side of the intermediate strut segment 53a, the high current wire and the low current wire may be isolated by the intermediate strut segment 53a .

For example, the gasket 7 is formed into a rectangular frame shape by an artificial resin, and the gasket 7 is disposed between the first and second top plate members 2A and 2B and the frame member 4.

Next, the mounting sequence of the floor socket device according to the present embodiment will be explained with reference to Figs.

As shown in FIG. 11A, a recess is formed on one side of each floor material 100. When the floor material 100 is disposed end to end, the floor socket device 1 described above is disposed in a rectangular connecting hole 101 defined by a recess of the floor material.

As shown in Fig. 9A, the connecting screw 28 is first inserted into the insertion holes 26 and 27 of the first top plate member 2A, and is screw-fitted to the connecting bracket 33 of the first wiring device block 3A, whereby the first top plate member 2A is to be attached. It is temporarily assembled with the first wiring device block 3A.

Subsequently, in a state where the first top plate member 2A and the first wiring device block 3A are temporarily assembled together, the first wiring device block 3A is inserted through the connection hole 101 into the bottom side of the floor material 100. As shown in FIG. 9B, the first top plate member 2A is placed at the peripheral portion of the connection hole 101. Although not shown in FIGS. 9A-9E, the abutting section 25 of the first top plate member 2A is in contact with the end surface of the connecting hole 101 in the foregoing state, thereby determining the mounting position of the first top plate member 2A. For the sake of simplicity, one of the flooring materials 100 is not shown in Figure 9B. In this state, the connecting screw 28 is screwed to sandwich the floor material 100 between the first top plate member 2A and the first wiring device block 3A, whereby the first top plate member 2A and the first wiring device block 3A are temporarily suspended. Ground to the flooring material 100.

Next, in a state where the second top plate member 2B and the second wiring device block 3B are temporarily assembled together, the second wiring device block 3B is inserted into the bottom side of the floor material 100 through the connection hole 101. At this time, in a state where the joint portions 23a of the first and second top plate members 2A and 2B are joined to each other, and the joint portions 24a of the first and second top plate members 2A and 2B are engaged with each other, the second top plate member 2B is placed at the joint. The peripheral portion of the hole 101. In this state, the connecting screw 28 is screwed to sandwich the floor material 100 between the second top plate member 2B and the second wiring device block 3B, whereby the second top plate member 2B and the second wiring device block 3B are temporarily The floor material 100 is fixed to the floor material.

Thereafter, as shown in FIG. 9D, the partition member 6 is inserted into the connection hole 101. The fixing screw 6c is inserted into the insertion hole 6b of the partition member 6, and is screw-fitted to the screw hole of the fixing portion 33g, whereby the partition member 6 is fixed to the first and second wiring device blocks 3A and 3B.

Next, as shown in FIG. 10A, the carpet 103 is unfolded on the upper surface of the floor material 100. The spacer 7 is placed on the upper surfaces of the first and second top plate members 2A and 2B. The frame member 4 is disposed on the liner 7. Next, the connecting screw 44 is inserted into the insertion holes 43a and 43b of the frame member 4, and is screw-fitted into the corresponding screw holes 29a and 29b of the first and second top plate members 2A and 2B, thereby fixing the frame member 4 to First and second top plate members 2A and 2B. Finally, the covering member 5 is rotatably coupled to the frame member 4, thereby completing the installation of the floor socket device 1.

The sequence of connecting the electric wires to the floor outlet device 1 of the present embodiment will be explained with reference to Figs. 12A-12G. Fig. 12A shows that the cover 50 and the wire access door 53 are in a closed state. In this state, the cover 50 is kept closed by a holder device (not shown). The wire access door 53 also remains closed because the leg segments 53a can interfere with the support segments 42 of the frame member 4. If the opening/closing button 54 is slid in the opening direction in this state, the holding state provided by the holder device is released, and the cover plate 50 is provided by a leaf spring provided on the bottom side of the cover 50 (not shown) The partial pressure is slightly opened (refer to Fig. 12B). In this state, the cover 50 is moved in the opening direction (the direction indicated by the arrow D1 in Fig. 12C). In a state where the cover 50 is broadly opened, wiring is performed with respect to the power outlet 31A or the LAN socket 31B. In order to pull out the wire connected to the power outlet 31A or the LAN socket 31B, along the opening direction (Fig. The wire passage door 53 is rotated in the direction indicated by the arrow D2 in 12D. At this time, the rotation angle of the wire passage door 53 is restricted by the stopper (not shown). When the wire access door 53 is kept open, the cover 50 is moved in the closing direction (the direction indicated by the arrow D3 in Fig. 12E). The cover 50 is further moved in the closing direction (the direction indicated by D4 in Fig. 12F) against the biasing force of the leaf spring. When fully closed, the cover 50 is held closed by the retainer device. The strut section 53a of the wire access door 53 remains placed on the support section 42, and the wire access door 53 remains open (refer to Fig. 12G). The wires are pulled from the space between the adjacent pillar segments 53a to the outside. Since the wire access door 53 remains open, the wire cannot be crushed between the wire access door 53 and the floor material 100, even when the wire access door 53 is gradually lowered. This may protect the wires.

In the above sequence, wiring can be performed by opening the cover 50. Next, the cover 50 can be closed while the wire access door 53 remains open. In the reverse order of the above sequence, the wire access door 53 can be switched from the open state to the closed state.

As described above, the floor socket device 1 of the present embodiment includes the first and second top plate members 2A and 2B, the first and second wiring device blocks 3A and 3B, the frame member 4, and the joint portions 23a, 23b, 24a, and 24b. The first and second top plate members 2A and 2B are disposed on the top side of the connection hole 101 of the floor material 100, and on the opposite side of the connection hole 101, wherein the connection hole 101 is disposed between the opposite side edges. The first and second wiring device blocks 3A and 3B are inserted into the connection hole 101 and are disposed on the bottom side of the floor material 100. The first and second wiring device blocks 3A and 3B are connected to the floor material by sandwiching the floor material 100 between the first and second wiring device blocks 3A and 3B and the first and second top plate members 2A and 2B. 100. The frame member 4 is provided to cover the first and second top plate members 2A and 2B, and the frame member 4 is fixed to the front surfaces of the first and second top plate members 2A and 2B by screws. The first and second top plate members 2A and 2B are joined to each other by the joint portions 23a, 23b, 24a, and 24b.

Since the first and second top plate members 2A and 2B provided on the opposite sides of the connection hole 101 are joined to each other by the joint portions 23a, 23b, 24a, and 24b, the first and second top plate members 2A and 2B are determined. relative position. Therefore, it is possible to reduce the screw hole 29a In alignment with 29b, the screw holes 29a and 29b are formed in the first and second top plate members 2A and 2B to fix the frame member 4 using screws. This makes it easy to perform the task of fixing the frame member 4 to the first and second top plate members 2A and 2B with screws, thereby improving the mounting convenience.

As shown in FIG. 10A, a curved surface is formed in the peripheral portion 104 of the connecting hole 101 on the lower surface of the floor material 100. When the floor material 100 is clamped between the first top plate member 2A and the first wiring device block 3A and between the second top plate member 2B and the second wiring device block 3B by screwing the connecting screw 28, the adjacent segment 33c is in contact with the peripheral portion 104 of the lower surface of the floor material 100. The tensile force thus acting in the direction indicated by the arrow in Fig. 10A is applied to the first and second top plate members 2A and 2B. In other words, a tensile force generating unit is provided which clamps the floor material 100 between the first top plate member 2A and the first wiring device block 3A by tightening the connecting screw 28, and the second top plate member 2B When being interposed between the second wiring device block 3B, a tensile force that is distant from each other is generated between the first and second top plate members 2A and 2B. In this regard, the tensile force generating unit is composed of a top plate member (first and second top plate members 2A and 2B), and an abutting portion 33c of the joint bracket 33, which cooperates with the abutting portion 33c of the joint bracket 33 to clamp A floor material 100 having a connection hole 101 having a peripheral portion of a curved surface shape is held.

Since the tensile force generating unit generates tensile forces apart from each other between the first and second top plate members 2A and 2B joined to each other, the relative positions of the first and second top plate members 2A and 2B are accurately determined, and further The misalignment of the screw holes 29a and 29b is reduced. This makes it easy to perform the task of fixing the frame member 4 to the first and second top plate members 2A and 2B with screws, thereby improving the mounting convenience.

In the present embodiment, as shown in FIG. 11B, the concave portion 102 having a height smaller than the remaining portion is formed in the peripheral portion of the connecting hole 101 on the upper surface of the floor material 100. The floor socket device 1 of the present embodiment preferably further includes a spacer 8 (for example, composed of an elastic material (for example, rubber or the like)), the spacer 8 is disposed in the recess 102, and is inserted in the first Between the second top plate members 2A and 2B and the floor material 100.

Therefore, even if there is a level difference on the upper surface of the floor material 100, the level difference (the recess 102) can be removed by the spacer 8. This helps stabilize the first and second The mounting of the top plate members 2A and 2B thereby stabilizes the mounting position and mounting strength of the first and second top plate members 2A and 2B. Due to the stability of the mounting position and the mounting strength of the first and second top plate members 2A and 2B, it is possible to increase the load capacity of the frame member 4 and the covering member 5, and to enhance the resistance against the person who is walking when the frame member 4 and the covering member 5 are walked. The durability of the running load applied under the time. The spacer 8 is preferably composed of an elastic material. The thickness of the spacer 8 is preferably equal to the depth of the recess 102.

In the present embodiment, a high current wiring device (for example, a power outlet 31A) is connected to the first wiring device block 3A. A low current wiring device (for example, a LAN outlet 31B) is connected to the second wiring device block 3B.

As described above, the combination of the first top plate member 2A and the first wiring device block 3A, and the combination of the second top plate member 2B and the second wiring device block 3B can be connected to the floor material 100 independently of each other, regardless of which combination is connected first. . This may perform high current wiring tasks and low current wiring tasks independently of each other. When the high current wiring task is performed, it is not necessary to remove the second wiring device block 3B for low current use. Also, when the low current wiring task is performed, it is not necessary to remove the first wiring device block 3A for high current use. Therefore, the low current wiring task and the high current wiring task can be performed independently of each other. This provides the advantage of better operability.

In the present embodiment, the frame member 4 includes an opening 41 and a support portion, the opening 41 being substantially the same size as the connecting hole for rotatably supporting the covering member 5 in the outer edge portion of the opening 41 (the support) The portion is a shaft hole 45 for supporting the shaft 51 of the covering member 5, and the covering member 5 can openly close the opening 41. The screw holes 29a and 29b formed in the first and second top plate members 2A and 2B and used to fix the frame member 4 by screws are disposed such that the position of the support portion can be mounted relative to the first and second wiring device blocks 3A and 3B. Position and position. As shown in Fig. 8A, the distance L1 between the two screw holes 29a and 29a existing in the vicinity of the shaft 51 is larger than the distance L2 between the remaining two screw holes 29b and 29b. Therefore, when the rectangular frame-like frame member 4 is placed on the first and second top plate members 2A and 2B, the orientation of the frame member 4 is fixed to a specific direction.

This provides the advantage that the frame member 4 is not installed in the wrong direction.

In the present embodiment, the group of the first top board member 2A and the first wiring device block 3A The combination of the second top plate member 2B and the second wiring device block 3B is disposed on the opposite side of the connection hole 101 having a rectangular opening shape. The high current wiring device is connected to the first wiring device block 3A. The low current wiring device is connected to the second wiring device block 3B. The wire access door 53 is openably disposed in a region of the cover member 5 opposite to the first wiring device block 3A, and wires connected to the first and second wiring device blocks 3A and 3B can pass through the wire access door 53.

As described above, the frame member 4 cannot be installed in the wrong direction. Therefore, the wire access door 53 of the covering member 5 is disposed in the region of the covering member 5 opposite to the first wiring device block 3A. The high current wiring device is connected to the first wiring device block 3A. A wire having a diameter larger than a wire diameter connected to the low current wiring device is connected to the high current wiring device. Since the wire access door 53 is disposed in the region of the cover member 5 opposite to the first wiring device block 3A, the wire connected to the first wiring device block 3A can be withdrawn from the wire access door 53 without possibly being bent. This makes it easy to perform wiring work. Compared to the case where the wire is bent, the possibility of disconnection of the wire may be lowered, thereby improving safety. The low current wiring device is connected to the second wiring device block 3B. A wire having a smaller diameter than a wire connected to a high current wiring device is connected to the low current wiring device. The wires connected to the low current wiring device can be easily bent. Therefore, even if the wire access door 53 is disposed on one side of the second wiring device block 3B, the wiring work can be easily performed.

At least one of the first wiring device block 3A and the second wiring device block 3B preferably includes a wire holder for holding the wire to be disposed on the bottom side of the floor material 100 and connected to the first wiring device block 3A or Two wiring device block 3B. In the present embodiment, the wire fixing member 34 having the insertion hole 34a is connected to the connection bracket 33 of the first wiring device block 3A (refer to Figs. 4A and 4B) for passing the binding tape. The wire holder is composed of a wire fixing member 34.

Therefore, the electric wire connected to the first wiring device block 3A is fixed with respect to the first wiring device block 3A. Therefore, it is possible to prevent an excessive force applied to the terminal portion of the first wiring device block 3A due to a change in the position of the electric wire, and to prevent the electric wire from being forcibly bent and subjected to an excessive load. In the present embodiment, the wire holder is provided only in the first wiring device block 3A. However, the wire holder may be disposed in the second wiring device block 3B in.

Although the invention has been shown and described in terms of embodiments, the invention is not limited thereto. It will be appreciated by those skilled in the art that various changes and modifications can be made without departing from the scope of the invention as defined by the appended claims.
