(Fig. 3) is axially supported on the upper part of the base 6 via a hinge mechanism 16 (Fig. 4) with an axis, and lifts upward while holding the cover 5, As shown in Fig. 1, the base 6 and the wiring mechanism 2 are configured to be exposed.

A force is applied to the cover body 5 in the direction closed by the coil spring 10 (FIG. 3). When the hand holding the cover body 5 is released, the cover body 5 is opened by the biasing force of the coil spring 10 ( It returns to the covering position (FIG. 2) from FIG. By such a structure, the situation in which the cover body 5 remains open and water splashes on the wiring mechanism 2 is suppressed.

Moreover, the notch 5i is formed in the lower part of the cover body 5, and in the state in which the cover body 5 is in the cover | cover position, the wiring 3 is made by the said notch 5i and the lower end part of the base 6. The insertion hole of the is formed. A packing 8 is attached to this notch 5i to suppress water from entering.

Further, a frame-shaped packing 7 (FIG. 3) is mounted between the base 6 and the wall surface W, whereby water is prevented from entering between the base 6 and the wall surface W into the internal space. The wiring mechanism 2 is provided to protrude on the surface 6a of the base 6 in a state where a part is inserted into the substantially rectangular opening 6d formed in the center portion of the base 6.

The hinge mechanism 16 has the structure as shown in FIG. That is, the projection part 6b formed in the upper end part of the base 6 is inserted in the notch part 5c provided in the upper wall part 5b of the cover body 5, and these upper wall part 5b and the projection part 6b are inserted. The rotary shaft 9 is fitted so as to pass through the through holes 5d and 6c formed therein, so that the base 6 and the cover body 5 are rotated with the rotary shaft 9 as the center of rotation. Has been obtained in which the rotational motion becomes relatively relatively possible. The coil spring 10 is wound around this rotational movement shaft 9, and a force is applied in the direction in which the cover body 5 is closed with respect to the base 6 by the coil spring 10. In addition, in this embodiment, the coil spring 10 is arrange | positioned at the substantially center part of the horizontal direction of the base 6, and the fitting part of the notch part 5c and the projection part 6b is arrange | positioned so that it may be interposed from both left and right sides. .

In this type of spinning cover 1, it is difficult to completely prevent water from entering the interior space of the spinning cover 1 from the gap between the boundary of the cover 5 and the base 6. In particular, when the hinge mechanism 16 is provided above the spinning cover 1 as in the present embodiment, as shown in FIG. 6 and the like, the upper wall portion 5b (notch portion 5c) of the hinge mechanism 16. And a gap between the protrusion 6b is formed, and water may stay above the gap, and the water may enter the internal space through the gap between the base 6 and the cover 5 from above. . Therefore, in this embodiment, the inner wall 11 is interposed between the wiring mechanism 2 and the cover body 5, specifically, above and to the side of the wiring mechanism 2 on the surface 6a of the base 6. The inner wall 11 having a substantially C-shaped shape is provided in a planar view to prevent the water entering the spinning cover 1 and to drain the water away from the wiring mechanism 2. Moreover, the upper wall part 11a does not make a perfect flat surface, but is inclined gradually downward toward the side from the center part, and water discharge | release property is improved. In addition, the lower part of the inner wall 11 is cut out for the insertion of the wiring 3.

In addition, in this embodiment, another member (parts other than the cover wall 5 or the inner wall 11 of the base 6) located on the opposite side to the wiring mechanism 2 with respect to the inner wall 11 and the inner wall 11. To form gaps G1 (FIG. 4) and G2 (FIG. 5) of appropriate sizes, and to generate capillary phenomena in the gaps G1 and G2 so as to transfer water in the desired direction and to promote drainage. Doing.

Specifically, as shown in FIG. 4, between the upper wall portion 11a of the inner wall 11 and the upper wall portion 5b of the cover 5, the transverse direction along the wall surface W (in this embodiment, substantially horizontal direction). A strip-shaped gap G1 that extends in a square) is formed, and water is transferred in the transverse direction along the wall surface W. The size of the gap G1 is appropriately set according to the water repellency of the upper wall portions 5b and 11a, the amount of water entering the inner wall 11, and the like. Further, fine grooves or protrusions along the extending direction of the inner wall 11 may be provided on the upper surface of the upper wall portion 11a or the lower surface of the upper wall portion 5b to promote drainage along the extending direction of the gap G1. good. In addition, the water transferred to the gap G1 descends on the side wall portion 11c of the inner wall 11.

In addition, as shown in FIG. 5, the protruding wall portion 11b extending from the upper wall portion 11a and the upper wall portion 11a of the inner wall 11 in a direction away from the wall surface W and the upper abdomen portion 5b of the cover body 5. ), A gap G2 extending in a direction away from the wall surface W (in this embodiment, substantially horizontal direction) is formed, and water is transferred in a direction away from the wall surface W. The size of the gap G2 is appropriately set according to the water repellency of the upper wall portion 5b, the upper wall portion 11a, the protruding wall portion 11b, the amount of water entering the inner wall 11, and the like. Further, fine grooves or protrusions along the extending direction of the inner wall 11 are provided on the upper surface of the upper wall portion 11a, the upper surface of the protruding wall portion 11b, or the lower surface of the upper wall portion 5b to extend along the extending direction of the gap G1. The drainage may be promoted.

Here, in this embodiment, the tip of the protruding wall portion 11b is extended to the vicinity of the boundary between the upper wall portion 5b of the cover body 5 and the ceiling wall portion 5e of the outer expansion protrusion 17, and is provided in the gap G2. The water for conveying the water is lowered by flowing along the inner surface of the cover 5 (inner surface of the ceiling wall portion 5e). By doing in this way, water splashing to the wiring mechanism 2 can be suppressed more reliably, and the inner surface of the ceiling wall part 5e flows, and a drainage path can be ensured with a simple structure.

In addition, in this embodiment, the shape of the upper wall part 11a is formed asymmetrically. Fig. 7 is a front view showing the top wall portion 11a exaggerated in the up and down direction, but specifically, as shown in Fig. 7, the spinning cover 1 (base) is formed at the position M1 which becomes the convex vertex of the top wall portion 11a. The distance is shifted by the distance δ on the left side from the horizontal center M of (6)).

When water enters the upper wall portion 11a, water droplets may form on the upper wall portion 11a due to its surface tension. However, according to the left-right asymmetric structure of the present embodiment, the inclination of the upper surface of the upper wall portion 11a is inclined. Is different from right to left, the gravity of the water droplets on the upper wall portion 11a is broken by the gravity, and the water stays on the upper wall portion 11a due to the surface tension. The splashing of water can be suppressed.

In addition, the present embodiment intentionally provides a water leakage passage for easily entering the water from the outside of the spinning cover 1 onto the upper wall (11a), the amount of water entering the upper wall (11a) is asymmetrical left and right I am trying to.

Specifically, between the notch part 5c (upper part 5b) and the projection part 6b of the hinge mechanism 16 as a leak path at the position near the right side from the horizontal center part of the upper wall part 5b from the front. The notch 5h (FIG. 8) which connects the clearance gap and the inside of the spun cover 1 is formed, and as shown in FIG. 7 by increasing the inflow amount of water from this notch 5h, the water of the right side water is seen from the front. The amount of entry is increased compared to the left side.

By doing so, the left and right balance of the water droplets on the upper wall portion 11a is broken down by the left and right difference in the amount of water entered, and the water stays on the upper wall portion 11a due to the surface tension. In 2), water splashing can be suppressed from above.

In addition, in such a configuration, the inclined surface that is continuously inclined in a predetermined direction is formed on the upper wall portion 11a over a wider section at a position where more water enters, thereby promoting the flow of water by gravity and causing the water droplets to flow. It is desirable to suppress the formation more reliably.

In addition, in this embodiment, this notch 5h is formed only in the inner surface side of the cover body 5, and as shown in FIG. 6, it cannot prevent that apparently the notch 5h is formed. In addition, if the notch 5h is extended to the outer surface side of the cover body 5, there is a concern that irrationality such as dust entry or blockage may occur as long as the enlarged gap is exposed, but the notch 5h is covered as in the present embodiment. By leaving it on the inner surface of the sieve 5, this can be suppressed.

On the other hand, in the present embodiment, as described above, the notch 5i formed in the lower portion of the cover 5 is attached with a packing 8 for suppressing the entry of water. This packing 8 is provided with the frame part 8a which fits in the notch 5i, and the wrinkle part 8b formed by the vertical and horizontal notch 8c inside the said frame part 8a. The sealing property is improved by deforming along the circumferential wall of the wiring 3 through which the wrinkle part 8b is inserted.

9, the plate-shaped rib 15 is provided in the position adjacent to the upper side (namely, inside of the cover body 5) of the packing 8 of the lower part of the cover body 5, and the packing 8 ) Is bent in the inward direction of the cover body 5 (inner space side of the spinning cover 1). As a result, it is possible to suppress the ingress of water from the outside along the packing 8 bent inwardly, and the ingress of water is also suppressed by the rib 15 itself. The rib 15 is provided with a notch 15a through which the wiring 3 is inserted. However, the direction of movement of the wiring 3 is regulated by the notch 15a. 3) is excessively bent, the notch 8c is widened, and the sealing property can be suppressed from deteriorating.

In addition, in this embodiment, as shown to FIG. 9 and FIG. 10, the engagement mechanism which engages the cover body 5 and the base 6 is provided adjacent to the notch 5i. Specifically, engagement projections 13 and 13 are provided at corner portions on the left and right sides of the base 6 side of the notch 5i, while the engagement recesses 14 and 13 corresponding to this are provided on the base 6. 14 is provided and these engaging projection 13 and the engaging recess 14 are comprised so that it may engage. The area adjacent to the notch 5i deteriorates the rigidity and tends to bend, and furthermore, the packing 8 tends to deform beyond the notch 5i. However, the provision of such a fastening mechanism suppresses the decrease in the rigidity of this part. can do. The gap between the engaging mechanisms can also be used as a discharge port for discharging water from the inside of the spinning cover 1.

In addition, in this embodiment, as shown in FIG. 10, the outer side expansion protrusion part 17 extended in the up-down direction which extended and protruded outward from the outer wall part 5a by predetermined width is formed in the horizontal direction center of the cover body 5, and is formed. It is. The outer inflation protrusion 17 extends upward and downward in the form of a strip of a predetermined width (about 1/3 of the width of the cover body 5) to the ceiling wall portion 5e and side wall portions 5f on both sides thereof. As a result, the cross section is formed in a substantially U shape. The ceiling wall portion 5e gradually rises from the upper edge of the outer wall portion 5a, and its height gradually increases in a parabolic shape from the upper portion to the lower portion through the central portion, and becomes substantially constant from the central portion to the lower portion. have. Moreover, the non-slip part 12 which consists of minute unevenness | corrugation (for example, stripe-shaped or point-shaped unevenness | corrugation) is provided in the surface of the side wall part 5f.

By this structure, the cover body 5 can be opened easily by lifting the outer expansion protrusion 17. In addition, the cover body 5 can be gripped more reliably only by the provision of the anti-slip part 12.

In addition, since the upper end portion of the ceiling wall portion 5e of the outer expansion protrusion 17 is close to the wall surface W, as shown in FIG. 5, the protruding wall portion 11b of the inner wall 11 at the upper end portion of the ceiling wall portion 5e. ) Can be easily approached to the upper end of the ceiling wall portion 5e, and the inner surface of the ceiling wall portion 5e can be secured as a drainage path. In addition, water is routed more reliably while transferring the water on the inner surface of the ceiling wall portion 5e by gently moving the ceiling wall portion 5e away from its upper end portion and away from the wall surface W side, that is, from the wiring mechanism 2 side. Splashing on the mechanism 2 can be suppressed.

According to the present embodiment described above, water is formed by forming the gaps G1 and G2 which are large enough to cause capillary phenomenon by the inner wall 11 and the member (upper wall portion 5b) different from the inner wall 11. Since it can convey in a desired direction, the wiring mechanism 2 can be protected from water by a simpler structure.

In addition, according to the present embodiment, water entering the inner wall 11 (upper wall portion 11a) is distributed and transported from the upper side of the wiring mechanism 2 in the transverse direction along the wall surface W and away from the wall surface W. Since it is possible to prevent water from splashing on the wiring mechanism 2 from above, it can be more surely suppressed.

Further, according to the present embodiment, the left and right balance of the water droplets is broken down on the upper wall portion 11a by generating a left and right difference in the amount of water entering the inner wall 11 (upper wall portion 11a). It is possible to suppress water from remaining on the surface 11a by surface tension, and to prevent water from splashing on the wiring mechanism 2 from above.

Further, according to the present embodiment, the left and right balance of water droplets is broken down on the upper wall portion 11a by the left and right difference in the shape of the inner wall 11 (upper wall portion 11a) above the wiring mechanism 2, It is possible to suppress the water from remaining on the upper wall portion 11a by the surface tension, and to prevent the water from splashing on the wiring mechanism 2 from above.

Further, according to the present embodiment, the packing 8 is bent inwardly by the ribs 15 to prevent the gap between the wiring 3 and the gap between the wiring 3 and the gap. Water can be prevented from entering the interior space.

In addition, according to this embodiment, since the engaging mechanism for engaging the cover body 5 and the base 6 is provided adjacent to the notch 5i, the notch 5i and further the packing 8 are provided. It becomes difficult to deform | transform, and it can suppress that water enters into an internal space from the clearance gap between the packing 8 and the wiring 3.

Moreover, according to this embodiment, there exists an advantage that the cover body 5 becomes easy to grasp and it is easy to open and close as much as the outside expansion protrusion 17 can be used as a holding part. Moreover, the inside of the outer side expansion protrusion 17 which is substantially U-shaped in cross section becomes a groove | channel which discharges water downward, and can discharge water more reliably. In addition, it is preferable that the width of the outer expansion protrusion 17 be a suitable size that is easy to grasp.

In addition, according to the present embodiment, the cover body 5 can be more reliably grasped by the part provided with the anti-slip part 12 in the outer expansion protrusion 17. In particular, when the outer expansion protrusion 17 is provided and the cover 5 is made of a transparent material, the anti-slip 12 is formed on the side wall portion 5f of the outer expansion protrusion 17. Even if the transparency through the anti-slip part 12 is lowered, there is an advantage that it does not become an obstacle for visual observation as much as one can visually observe the internal connection state from the ceiling wall part 5e.

As mentioned above, although this invention was described about preferable embodiment, this invention is not limited to the said embodiment, A various deformation | transformation is possible.

For example, in the above embodiment, the case where the power supply outlet device is provided as the wiring mechanism is exemplified, but instead, it may be configured as a wiring mechanism for connecting a switch or other wiring.

Moreover, the shape of a spinning cover can also be variously modified. For example, in the said embodiment, although the cover body was made to be vertically open, it may be made to be horizontally open, and it can implement also when the wiring introduction position (position of the notch 5i) is set to other than lower center part.

In the above embodiment, a gap for transferring water by using capillary phenomenon is formed above the wiring mechanism, but the same gap may be formed in other parts such as the side and the bottom of the wiring mechanism.

In addition, it is good also as a water leak passage | path by widening a clearance gap in a hinge mechanism.

In addition, as in the base 6A shown in FIGS. 11A and 11B, an end wall portion 11d extending upward is provided at the end edge on the side far from the wall surface W of the upper wall portion 11a, and the image is over the end edge. You may suppress that water enters below the wall part 11a. Even with such a configuration, the spinning performance can be improved relatively easily without providing a packing or the like.

According to the present invention, since the water can be transported in the desired direction by forming a gap of the size that causes the capillary phenomenon by the inner wall and other members, the wiring mechanism is protected from the water by a simpler configuration. can do.

Further, according to the present invention, since water can be transported in the transverse direction along the wall surface from the upper side of the wiring mechanism, water can be prevented from splashing from the upper side on the wiring mechanism.

In addition, according to the present invention, since water can be transferred in a direction away from the wall surface at the upper side of the wiring apparatus, it is possible to suppress the splashing of water from the upper side on the wiring apparatus.

Further, according to the present invention, the left and right balance of water droplets is broken down on the inner wall above the wiring mechanism by the left and right difference of the quantity of water entered, and the water stays on the inner wall by surface tension, and the wiring mechanism is restrained from above. The splashing of water can be suppressed.

Further, according to the present invention, it is possible to prevent water from entering the wiring mechanism side beyond the end edge of the inner wall above the wiring mechanism by the end wall portion.
