Description

Ground Power Outlet Cover Assembly

technical field

The invention relates to a ground power socket cover assembly.

Background technique

In offices or other places, ground sockets are located on the surface of the floor (for example, see paragraphs [0005]-[0011] and accompanying drawings 1-3 of Japanese Utility Model Application Publication No. H7-11828 (JP7-11828A)). Such a ground socket includes a ground box main body, a cover and a wire access door, in which a power socket, a telephone connection terminal, etc. An opening in the top surface of the ground box main body, the wire access door is connected to a cable exit hole formed by cutting along a portion of the edge of the cover on the side opposite the axis of the cover.

In this floor socket, when the cable is not connected to the floor socket, the wire passage door closes the cable outlet hole formed in the cover, thereby preventing garbage or dust from entering the floor box main body. To connect a cable to this floor socket, the cover is opened, the cable is connected to the power socket, and the cable access door remains open until the cover is closed. Then, the wire access door is fixed at a predetermined angle, thereby protecting the cables.

Referring to FIG. 2 , the frame member 4 is formed by, for example, aluminum die casting to have a rectangular frame-like shape having four sides of substantially equal length. The frame member 4 has a rectangular opening 41 formed in its central area. A support portion 42 on which a part of the cover member 5 is placed when the cover member 5 is closed is formed on a peripheral edge of the opening 41 to protrude inward from three sides except one. Four insertion holes 43 a and 43 b into which attachment screws 44 are inserted are formed in the support portion 42 at positions corresponding to the screw holes 29 a and 29 b of the first and second top plate members 2A and 2B. The cover member 5 is rotatable about a rotation axis parallel to the side of the peripheral edge of the opening 41 on which the support portion 42 is not formed. A shaft hole 45 for rotatably supporting a shaft 51 of the cover member 5 is formed at the peripheral edge of the opening 41 (only one shaft hole is shown in FIG. 2 ). In this embodiment, when the wire passage door 53 (to be explained below) is in an open state, the leg portion 53a provided on the wire passage door 53 is in contact with the support portion 42 (see FIG. 1 ), whereby the support portion 42 forms a second a support part.

The cover member 5 includes a cover main body 50 formed into a rectangular plate shape by, for example, aluminum die casting. A shaft 51 protrudes from the opposite side of one end of the cover plate 50 . A wire passage opening 52 through which wires (not shown) connected to the first and second wiring device groups 3A and 3B pass is formed at an edge of the cover main body 50 from which one of the shafts 51 protrudes. The support portions 50c are provided on two respective opposite sides of the peripheral edge of the wire passage opening 52, so that part of the wire passage door 53 can be supported on the support portions 50c. Further, horizontally elongated shaft holes 50 b into which a shaft 53 b serving as a rotation axis of the wire passage door 53 is inserted are formed on two respective opposite sides of the peripheral edge of the wire passage opening 52 . Two support portions (second support portions) 50 a on which portions of the wire passage door 53 are supported are provided in horizontal rows on the other side of the peripheral edge of the wire passage opening 52 . A recess is formed in one surface (upper surface in FIG. 2 ) of each support portion 50 a so that when the wire passage door 53 is in an open state, the corresponding edge of the wire passage door 53 (facing the cover main body 50 ) is placed in contact with the wire passage door 53 . The recesses are in contact.

A wire passage door 53 for openably closing the wire passage opening 52 is rotatably connected to the cover main body 50 . The wire passage door 53 is die-cast from, for example, aluminum in a horizontally elongated rectangular plate shape. Shafts 53 b protrude from respective opposite sides of an end portion (facing the cover main body 50 in FIG. 2 ) of the wire passage door 53 . The shaft 53 b is inserted into each shaft hole 50 b of the cover main body 50 and serves as a rotation axis of the wire passage door 53 . Legs 53 a (for example, three legs in FIG. 2 ) protrude downward from the lower surface of the wire passage door 53 and are spaced apart from each other at regular intervals. A stopper 53c and a stopper 53d are provided on each of the opposite left and right leg portions 53a. The stopper 53c limits the angle of rotation of the wire access door 53 when it is opened. When the wire passage door 53 is in the closed state, the stopper 53d contacts the rear surface of the cover main body 50, thereby preventing the wire passage door 53 from being lifted upward. As shown in FIG. 1, bushings 55 for protecting electric wires (not shown) inserted through the electric wire passage door 53 and provided under the floor are held between the legs 53a.

Each leg 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 passage door 53 is in the open state and a first side extending in the vertical direction when the wire passage door 53 is in the closed state. The second side of the extension. The central leg portion 53 a serves as a partition wall for isolating high-current wires such as power lines connected to the power outlet 31A from weak-current wires such as communication lines connected to the LAN outlet 31B. For example, if high current wires are provided on one side of the central leg 53a and if low current wires are provided on the other side of the central leg 53a, the high current wires can be separated from the low current wires by the central leg 53a.

The gasket 7 is formed into a rectangular frame-like shape by, for example, synthetic resin, and is provided between the first and second top plate members 2A and 2B and the frame member 4 .

The features of the floor power outlet cover assembly 8 of the present embodiment will now be described. Figure 1 is a bottom perspective view of the floor electrical outlet cover assembly 8 showing the cover body 50 and the wire access door 53 of the cover member 5 both closed. The wire passage door 53 is supported on support portions 50 a and 50 c provided on the cover main body 50 . The stopper 53d contacts the front end of the rear surface of the corresponding support portion 50c, thereby preventing the wire passage door 53 from being lifted upward. In this state, each shaft 53 b of the wire passage door 53 is disposed on the side (the right side in FIG. 1 ) of the corresponding shaft hole 50 b opposite to the opening side of the wire passage door 53 . In this embodiment, this position is referred to as the first position of the shaft 53b. After the cover main body 50 has been opened, if the wire passage door 53 is moved to the open side (left side in FIG. 1 ), the shaft 53b moves to the open side in the horizontally elongated shaft hole 50b, and the stopper 53d moves to their A position that does not contact the support portion 50c. As a result, the wire passage door 53 is allowed to be opened. In this embodiment, the open side within the shaft hole 50b is referred to as the second position of the shaft 53b. Thus, the shaft 53b of the wire access door 53 is movable within the shaft hole 50b between the first position and the second position.

FIG. 6B is a side sectional view of the floor power socket device 1 with the floor power socket cover assembly 8 of the present embodiment, which shows a state where the wire access door 53 is opened. In this state, the edge of the wire passage door 53 provided on the side opposite to the open side (the right side in FIG. 6B ) of the wire passage door 53 contacts the recess of the support portion 50 a provided on the cover main body 50 . Therefore, for example, even if an impact is applied to the wire passage door 53 from the open side (left side in FIG. 6B ), the impact is dispersed to the support portion 50a instead of concentrating the stress on the shaft 53b, thereby reducing the stress applied to the wire passage door 53. load on shaft 53b. In this embodiment, a recess formed in the support portion 50a constitutes a movement restricting portion.

Next, the installation sequence of the floor power outlet device 1 will be described with reference to FIGS. 10 and 11 .

As shown in FIG. 10A, the connecting screws 28 are first inserted into the insertion holes 26 and 27 of the first top plate member 2A, and are screw-fitted to the fixing portions 33d and 33e of the connecting bracket 33 of the first wiring device group 3A, whereby The first top plate member 2A and the first wiring device group 3A are temporarily assembled together.

After the first top plate member 2A and the first wiring device group 3A have been temporarily assembled together, the first wiring device group 3A is inserted into the bottom side of the flooring material 100 through the connection hole 101 . As shown in FIG. 10B , the first top plate member 2A is placed on the peripheral edge portion of the connection hole 101 . Although not shown in FIGS. 10A to 10E , the abutting portion 25 of the first top plate member 2A contacts the end face of the connection hole 101 in the aforementioned state, thereby determining the mounting position of the first top plate member 2A. For simplicity, only one of the two sides of the flooring material 100 is shown in FIG. 10B . In this state, the connecting screws 28 are tightened to sandwich the floor material 100 between the first top plate member 2A and the first wiring device group 3A, whereby the first top plate member 2A and the first wiring device group 3A are temporarily fixed to flooring material 100.

Thereafter, in a state in which the second top plate member 2B and the second wiring device group 3B have been temporarily assembled together, the second wiring device group 3B is inserted into the bottom side of the floor material 100 through the connection hole 101 . At this time, the second top plate member 2B is placed on the peripheral edge portion of the connecting hole 101, while the engaging portions 23a of the first and second top plate members 2A and 2B are engaged with each other and the engagement of the first and second top plate members 2A and 2B Portions 24a engage each other. In this state, the connecting screws 28 are tightened to sandwich the floor material 100 between the second top plate member 2B and the second wiring device group 3B, whereby the second top plate member 2B and the second wiring device group 3B are temporarily fixed to flooring material 100.

Subsequently, as shown in FIG. 10D , 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 screwed into the threaded hole of the fixing portion 33g, whereby the partition member 6 is fixed to the first and second wiring device groups 3A and 3B (see FIG. 10E ).

Next, as shown in FIG. 11A , a carpet 103 is laid on the upper surface of the flooring material 100 . The gasket 7 is placed on the upper surfaces of the first and second top plate members 2A and 2B. The frame member 4 is placed on the pad 7 . Thereafter, the attachment screws 44 are inserted into the insertion holes 43a and 43b of the frame member 4 and screw-fitted into the corresponding threaded holes 29a and 29b of the first and second top plate members 2A and 2B, whereby the frame member 4 is fixed to The first and second top plate members 2A and 2B. Finally, the cover member 5 is rotatably connected to the frame member 4, thereby completing the installation of the floor power outlet device 1 .

The sequence of connecting electric wires to the ground power outlet device 1 will be described with reference to FIGS. 12A to 12G .

Fig. 12A shows the cover body 50 and the wire access door 53 in a closed state. In this state, the cover main body 50 is kept closed by the latch hook 56 (see FIG. 1 ) integrated with the open/close button 54 . The wire passage door 53 is also kept closed because the stopper 53d is locked to the front end of the rear surface of the corresponding support portion 50c.

If the opening/closing button 54 is slid in its opening direction, the locked state possibly produced by the locking hook 56 is released and the cover main body 50 is slightly opened by the biasing force of a leaf spring (not shown), which is provided on the bottom side of the cover body 50 (see FIG. 12B ). In this state, the cover main body 50 is moved in the opening direction (direction indicated by arrow D1 in FIG. 12C ). After the cover main body 50 is opened widely, the wiring of the power outlet 31A or the LAN outlet 31B is performed. In order to lead out the wires connected to the power outlet 31A or the LAN outlet 31B, the wire passage door 53 is pulled outward (direction indicated by arrow D2 in FIG. 12D ) and rotated in an opening direction (direction indicated by arrow D3 in FIG. 12D ) . The reason for pulling the wire passage door 53 outward is to move the stoppers 53d to the second position where they do not contact the support portion 50c, thus allowing the wire passage door 53 to rotate in the opening direction. At this time, the rotation angle of the wire passage door 53 is limited by the stopper 53c. With the wire passage door 53 in the open state, the cover main body 50 moves in the closing direction (the direction indicated by the arrow D4 in FIG. 12E ).

The cover body 50 is further moved in the closing direction (direction indicated by arrow D4 in FIG. 12F ) against the biasing force of the leaf spring. When fully closed, the cover body 50 is held in the closed state by the latch hook 56 . The leg portion 53a of the wire passage door 53 is held on the support portion 42 and the wire passage door 53 is held open (see FIG. 12G ). The electric wires are led to the outside through the space between the adjacent leg portions 53a. Since the wire passage door remains open, there is no possibility of wires being crushed between the wire passage door 53 and the floor material 100 even when the wire passage door 53 is lowered. This makes it possible to protect the wires. In addition, as shown in FIG. 6B , the edge of the wire passage door 53 provided on the side (facing the cover main body 50 ) opposite to the opening side of the wire passage door 53 is in contact with the recess of the support portion 50 a. Therefore, even if an impact is applied to the wire passage door 53 from the open side, the impact is dispersed to the support portion 50a, thereby preventing stress from being concentrated on the shaft 53b, thereby reducing the load applied to the shaft 53b.

In the above sequence, wiring can be performed by opening the cover main body 50 . Then, the cover main body 50 can be closed with the wire passage door 53 kept open. By performing the reverse sequence to the above sequence, the wire passage door 53 can be switched from the open state to the closed state.

As described above, the floor outlet cover assembly 8 of the present embodiment includes the frame member 4 and the cover member 5 . The cover member 5 includes a cover main body 50 having a wire passage opening 52 through which a power supply wire passes, and a wire passage door 53 rotatably supported by the cover main body 50 and openably closing the wire passage Opening 52 . The wire passage door 53 has a shaft 53b as a rotation axis of the wire passage door 53, and a leg 53a at least partially supported on the support portion 42 provided on the frame member 4 when the wire passage door 53 is in an open state. In addition, a stopper 53d is provided on the leg portion 53a and contacts the rear surface of the cover main body 50 and prevents the wire passage door 53 from being lifted upward. In addition, the shaft 53b is supported to be movable in a direction perpendicular to the shaft 53b between a first position at which the stopper 53d contacts the rear surface of the cover main body 50 and a second position at which In the second position, the stopper 53d does not contact the rear surface of the cover main body 50 .

When the shaft 53b of the wire passage door 53 is in the first position, in other words, when the wire passage door 53 closes the wire passage opening 52, the stopper 53d is in contact with the rear surface of the support portion 50c of the cover main body 50, thus preventing the wire passage door from opening. 53 is lifted upwards. As a result, there is no possibility of a person tripping over the wire passage door 53, thus improving safety.

In this embodiment, as shown in FIG. 1 , when the shaft 53b is in the first position, preferably, the stopper 53d contacts the end of the rear surface of each support portion 50c provided on the cover main body 50 .

The reason for this is because the movement distance of the shaft 53d from a position where the stopper 53d is in contact with the support portion 50c to another position where the stopper 53d is not in contact with the support portion 50c can be reduced.

In this embodiment, the cover main body 50 has a support portion 50a on which a part of the wire passage door 53 rests when the wire passage door 53 is in an open state. When the wire passage door 53 is in the open state, the support portion 50a contacts the edge of the wire passage door 53 opposite to its opening side, thereby preventing the wire passage door 53 from being moved to the side opposite to the opening side.

Therefore, even if an impact is applied to the wire passage door 53 from the open side, the support portion 50a absorbs the impact, thereby preventing stress from being concentrated on the shaft 53b, thereby reducing the load applied to the shaft 53b.
