Figure 9 is a rear perspective view showing the sealing piece 20 locked in the open position Op relative to the base member 10. Note that the cover member 30 is not shown in Figures 4 through 9. Furthermore, elements with common functions may be given the same reference numeral or symbol.

[0010] As shown in Figure 1, the wiring cover 100 according to this embodiment is attached to the exterior surface of the exterior wall W of a building or the like. The wiring cover 100 can be used as an entry cover for small wire diameters (wire duct diameters) or as a service entrance cover for large wire diameters. The wiring cover 100 is attached to the exterior wall W in a watertight manner, covering the upper part of the base of the electric wire L exposed to the outside through the wiring hole H, and thus maintaining watertightness. Therefore, it is possible to prevent water such as rainwater from entering the building directly into the gap formed between the wiring hole H and the electric wire L, or from flowing along the surface of the exterior wall W.

[0011] In detail, the wiring cover 100 is positioned around the wiring hole H provided in the exterior wall W and includes a base member 10 that is fixed to the exterior wall W. This allows the cover member 30 to be attached via the base member 10 without directly attaching the cover member 30 to the exterior wall W. Thus, the base member 10 and the cover member 30 can reliably cover the space where the base portion of the electric wire L exposed from the exterior wall W is located.

[0012] As shown in Figures 3 to 9, the base member 10 has a frame portion 11 surrounding the electric wire L, a notch 12 through which the electric wire L can pass, and a sealing piece 20 that is fixed to the base member 10 and movable between a closed position Cl (see Figure 4 or Figure 5) and an open position Op (see Figure 8 or Figure 9) so as to be able to open and close the notch 12. The base member 10 has a through hole V in the center through which the electric wire L passes. The closed position Cl is the position in which the sealing piece 20 closes the notch 12 and is located below the through hole V. The open position Op is the position in which the sealing piece 20 retracts to open the notch 12 and is located below the base member 10. Preferably, the closed position Cl and the open position Op are on the same plane. This allows the sealing piece 20 to be moved parallel to the outer wall W or base member 10 and in a direction perpendicular to the extending direction of the electric wire L or wiring hole H, so as not to interfere with the routing of the electric wire L and the sealing piece 20 can open and close the notch 12. When the sealing piece 20 is in the closed position Cl, it is positioned to fill the space between the opposing notches 12. When the sealing piece 20 is in the open position Op, it is positioned to a position where it has retracted to a position where the electric wire L can pass between the opposing notches 12 (see Figure 8 or Figure 9). In this way, the sealing piece 20 can move between the closed position Cl and the open position Op so as to open and close the notch 12, so that the electric wire L remains protruding outwards from the outer wall W, the sealing piece 20 can be moved to the open position Op to pass the electric wire L through the notch 12, and the sealing piece 20 can be moved to the closed position Cl to attach the wiring cover 100 to the outer wall W. Furthermore, since the sealing piece 20 is movable while being anchored to the base member 10, the wiring cover 100 can be attached to the exterior wall W without the sealing piece 20 falling off the base member 10, even while the electric wire L is still protruding and extending outwards from the exterior wall W. Therefore, the wiring cover 100 is easy to attach to the exterior wall W and prevents the loss of the sealing piece 20.

[0013] The base member 10 includes a packing 40 interposed between the base member 10 and the outer wall W along the peripheral edge of the surface (rear surface) facing the outer wall W, and the packing 40 can form a watertight seal with the outer wall W. Accordingly, the root portion of the electric wire L exposed from the outer wall W can be covered in a watertightly sealed manner, and rainwater or the like can be prevented from entering the indoor space through the wiring through-hole H.

[0014] The base member 10 may have a window D that opens downward and allows the electric wire L to pass therethrough. The window D may be covered with a flexible partition plate having a cut. Accordingly, the electric wire L can be extended from the inner side to the outer side of the cover member 30, and entry of water such as rainwater into the interior of the wiring cover 100 from between the window D and the electric wire L can be suppressed.

[0015] The base member 10 has bolt holes 15 for inserting bolts for fixedly attaching the base member 10 to the outer wall W. Accordingly, the base member 10 can be directly attached to the outer wall W.

[0016] The cutout portion 12 of the base member 10 has a guide G (protrusion or groove) that allows the sealing piece 20 to move in the vertical direction, restricts the rearmost position in the front-rear direction, and enables positioning in the left-right direction. Accordingly, the sealing piece 20 can be positioned in the left-right direction and the front-rear direction with respect to the base member 10 while being movable in the vertical direction.

[0017] The sealing piece 20 is held in place by friction due to the elastic force R of the frame 11, allowing it to slide freely within the notch 12. Specifically, the sealing piece 20 is capable of translational movement relative to the base member 10. The elastic force R of the frame 11 is determined by the overall rigidity of the base member 10 and acts laterally in the notch 12, facing each other from the left and right, as shown by the arrows in Figure 4. The frictional force in the sliding direction S acting on the sliding surface between the notch 12 and the sealing piece 20 due to the elastic force R of the frame 11 is greater than the force acting on the sealing piece 20 due to gravity, and is easily overcome by the force applied by the user directly to operate the sealing piece 20. Thus, since the sealing piece 20 is held in place by friction due to the elastic force R of the frame 11, allowing it to slide freely within the notch 12, the user can open and close the sealing piece 20 with light force and move and position the sealing piece 20 to the correct position (closed position Cl).

[0018] The sealing piece 20 has a bolt hole 24 for inserting a bolt for fixing and attaching the base member 10 to the outer wall W. The sealing piece 20 may optionally have a cover to close the bolt hole 24. This allows the sealing piece 20 to be attached directly to the outer wall W independently of the base member 10. Therefore, with the sealing piece 20 in the open position Op, the electric wire L is inserted into the through hole V of the base member 10 fixed to the outer wall W, and then, with the electric wire L in the through hole V, the sealing piece 20 is moved to the closed position Cl, allowing the sealing piece 20 to be attached to the outer wall W independently of the base member 10.

[0019] As shown in Figures 5 to 9, the sealing piece 20 has a mooring pin 21. The base member 10 has a mooring groove 13 for mooring the mooring pin 21. This allows the sealing piece 20 to move between a closed position Cl and an open position Op without falling off the base member 10, even while the electric wire L is still extending outwards from the exterior wall W. Thus, the loss of the sealing piece 20 can be avoided.

[0020] Specifically, the mooring pin 21 is a columnar body erected substantially vertically from the rear surface of the sealing piece 20. The mooring pin 21 has a cylindrical rod shaft erected from the rear surface of the sealing piece 20, and a head formed at the tip of the rod shaft, having an outer diameter larger than the shaft diameter of the rod shaft. This allows the rod shaft of the mooring pin 21 to pass through a mooring groove 13 formed in the base member 10, which has a width larger than the shaft diameter of the rod shaft, and the head of the mooring pin 21 to hook into a mooring groove 13, which has a width smaller than the outer diameter of the head. Thus, the sealing piece 20 can be moored to the base member 10 in the open position Op (away from the base member 10).

[0021] The mooring groove 13 has an insertion hole 131 through which the mooring pin 21 can be inserted, and a slit 132 that can guide the mooring pin 21, communicates with the insertion hole 131, and has a width greater than the minimum diameter of the mooring pin 21 but smaller than the maximum diameter of the mooring pin 21. This allows the head of the mooring pin 21 to be inserted into the insertion hole 131 to secure the sealing piece 20 to the base member 10, and allows the head of the mooring pin 21 to be hooked into the slit 132, which has a width greater than the shaft diameter (minimum diameter) of the rod axis of the mooring pin 21, and a width smaller than the outer diameter (maximum diameter) of the head.

[0022] The sealing piece 20 is biased by the base member 10 and has a snap claw 22 that can lock the sealing piece 20 in the closed position Cl. As a result, when the sealing piece 20 slides along the guide G (protrusion or groove) formed in the notch 12 of the base member 10 and reaches the closed position Cl, the snap claw 22 receives a strong elastic force R from the notch 12, causing it to bend and increasing the frictional force. The snap claw 22 then snaps into place with the notch 12 and, as appropriate, locks into a projection formed in the notch 12, thereby keeping the sealing piece 20 in the closed position Cl (see Figure 5, etc.).

[0023] Preferably, the sealing piece 20 has a pair of outwardly biased snap claws 22 at symmetrical positions. This allows the sealing piece 20 to be held in place by the notch 12, and the sealing piece 20 can be securely retained in the closed position Cl.

[0024] The cover member 30 covers the upper part of the electric wire L that passes through the wiring hole H, enclosing the space formed in front of the base member 10, and is attached to the base member 10. This ensures that the upper part of the electric wire L is reliably covered by the cover member 30 and the base member 10, and the cover member 30 can be attached to the exterior wall W via the base member 10.

[0025] The base member 10 and the cover member 30 are detachably fixed together by the fastening member 50. This allows the cover member 30 to be securely locked to the base member 10 after it has been fitted and attached.

[0026] As shown in Figure 3, the base member 10 has base protrusions 14. The base protrusions 14 may be provided in pairs symmetrically on the front surface of the base member. The sealing piece 20 has sealing protrusions 23. The sealing protrusions 23 may be provided in pairs symmetrically on the front surface of the sealing piece 20. The cover member 30 has fitting grooves 31 that fit both the base protrusions 14 and the sealing protrusions 23. The fitting grooves 31 may be provided in pairs symmetrically on the rear surface of the cover member 30. The width of the fitting grooves 31 is the sum of the width of the base protrusions 14 and the width of the sealing protrusions 23. This allows the base member 10, the sealing piece 20, and the cover member 30 to be assembled without gaps, resulting in a stable structure without rattling. Thus, since the cover member 30 has a fitting groove 31 that fits both the base ridge 14 and the sealing ridge 23, the rigidity of the cover member 30, through the fitting groove 31, resists the outward reaction force (reaction force against the elastic force R) generated from the sealing piece 20 when it is in the closed position Cl, preventing the notch 12 of the base member 10 from expanding outward. Therefore, the elastic force R acting from the notch 12 of the base member 10 to the sealing piece 20 can be maintained, and the frictional force acting on the sliding surface between the notch 12 and the sealing piece 20 can be maintained. Thus, through the cooperation of the base member 10, the sealing piece 20, and the cover member 30, the sealing piece 20 can be securely held in the notch 12 so that it does not shift from the closed position Cl or fall out of the notch 12.

[0027] Preferably, the fitting groove 31 extends linearly along the vertical direction. This allows the cover member 30 to be easily attached by moving the cover member 30 vertically or in the front-to-back direction to align it with the assembly of the base member 10 and the sealing piece 20 at the portion where the base ridge 14 and the sealing ridge 23 overlap, while maintaining the function of sliding and translating the sealing piece 20 relative to the base member 10.

[0028] (How to install the wiring cover) The following describes an example of how to attach the wiring cover 100 to the exterior wall W.

[0029] (1) First, the sealing piece 20, which is anchored to the base member 10, is moved to the open position Op. Then, the electric wire L is passed through the notch 12 and the base member 10 is moved in parallel along the outer surface of the outer wall W from the outside to the inside. The base member 10, which has a packing 40 on its rear surface, is attached to the outer wall W so as to surround the wiring hole H through which the electric wire L is inserted. At this time, the frame portion 11 of the base member 10 is positioned so that it covers the area above the wiring hole H, i.e., above the electric wire L, and the notch 12 is positioned below the wiring hole H, i.e., below the electric wire L.

[0030] (2) Next, the sealing piece 20 is moved from the open position Op shown in Figures 8 and 9 so as to rotate around the anchoring pin 21 and placed on the guide G formed in the notch 12 as shown in Figures 6 and 7.

[0031] (3) The sealing piece 20 is slid upward along the guide G of the notch 12 to the closed position Cl shown in Figures 4 and 5.

[0032] (4) When the sealing piece 20 moves to the closed position Cl, the base ridge 14 and the sealing ridge 23 overlap, and the cover member 30 is attached to the assembly of the base member 10 and the sealing piece 20 by fitting that portion into the fitting groove 31 of the cover member 30.

[0033] (5) The cover member 30 is fixed to the base member 10 with bolts or the like as appropriate. The sealing piece 20 is fixed to the outer wall W with bolts or the like as appropriate.

[0034] In this way, the wiring cover 100 can be easily attached to the outer wall W surrounding the wiring hole H through which the electric wire L protrudes.

[0035] As described above, the wiring cover 100 according to the embodiment comprises a base member 10 that is arranged around a wiring hole H provided in the outer wall W and fixed to the outer wall W, and a cover member 30 that covers the top of the electric wire L, surrounds the space formed in front of the base member 10, and is attached to the base member 10. The base member 10 has a frame portion 11 that surrounds the electric wire L, a notch portion 12 through which the electric wire L can pass, and a sealing piece 20 that is fixed to the base member 10 and can move between a closed position Cl and an open position Op so that the notch portion 12 can be opened and closed. As a result, with the electric wire L still protruding outwards from the outer wall W, the sealing piece 20 can be moved to the open position Op to pass the electric wire L through the notch portion 12, and the sealing piece 20 can be moved to the closed position Cl to attach the wiring cover 100 to the outer wall W. Furthermore, since the sealing piece 20 is movable while being anchored to the base member 10, the wiring cover 100 can be attached to the exterior wall W without the sealing piece 20 falling off the base member 10, even while the electric wire L is still protruding and extending outwards from the exterior wall W. Therefore, the wiring cover 100 is easy to attach to the exterior wall W and prevents the loss of the sealing piece 20.

[0036] It should be noted that the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0037] Furthermore, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, without departing from the spirit of the present invention. Also, the above-described modifications may be combined as appropriate, without departing from the spirit of the present invention. [Explanation of Symbols]
