Including rectangular shape.

In the joint cover 10 of the present embodiment, the plane on the through hole 15 a side of the substantially elliptical tubular portion 15 is separated from the outer peripheral edge of the pedestal portion 16, and the convex curved surface portion of the substantially elliptical tubular portion 15 is the pedestal portion 16. An offset state in which the center of the long axis of the tubular portion 15 is shifted (offset) in the long axis direction of the tubular portion 15 from the center of the pedestal portion 16 in plan view (top view) so as to contact the outer peripheral edge (See FIGS. 3, 4C and 4E).
In the present embodiment, the upper end opening 15 b of the tubular portion 15 has the inner opening end 15 c located on the inner space side of the tubular portion 15, and when the projecting conduit portion 13 is included in the tubular portion 15, the projecting conduit The upper end in the axial direction of the portion 13 comes into contact with the inner opening end 15c at the end of storage. It should be noted that the upper end in the axial direction does not have to contact the inner opening end 15c when the protruding pipe portion 13 is enclosed. An annular rib that sandwiches and fixes the upper end portion of the projecting duct portion 13 in contact with the inner opening end 15c from the outside to the upper end surface of the inner space of the tubular portion 15 so as to surround the inner opening end 15c. 15d is provided to protrude toward the internal space.

In the present embodiment, the distance in the internal space of the tubular portion 15 between the inner opening end 15c of the tubular portion 15 and the upper surface of the flange portion 12 when the projecting conduit portion 13 is included in the tubular portion 15 is the projected tube. It becomes the inner surface height of the tubular portion 15 that encloses the passage portion 13.
In the present embodiment, the inner surface height h1 (see FIG. 5) of the tubular portion 15 is formed to be equal to or longer than the pipe length h2 (see FIG. 2) of the protruding conduit portion 13 of the joint 11, and the pedestal portion 16 is formed. The inner surface length a1 (see FIG. 5) along the bottom surface of the pipe 11 is equal to the outer surface length a2 along the bottom surface of the flange portion 12 of the pipe connecting portion 14 and the protruding pipe portion 13 in the pipe connecting portion 14 (FIG. 2). (See above) The outer surface length a <b> 2 is the entire length (longitudinal length) of the pipe connecting part 14 and the protruding pipe part 13 in a plan view (top view) of the joint 11.

  For this reason, the tubular part 15 of the present embodiment covers the tubular part 15 from above the pipe connecting part 13 and the protruding pipe part 14, and the protruding pipe part 13 and the pipe connecting part 14 of the joint 11 are connected to the tubular part. 15 can be housed and enclosed, and then the pipe connecting portion 14 can be protruded from the through hole 15a. If the protruding pipe part 13 and the pipe connecting part 14 of the joint 11 can be housed and contained in the tubular part 15, the tubular part 15 has a substantially elliptical shape in plan view (top view). The shape in plan view (top view) and the overall shape may be other shapes such as a circular shape, a quadrangular shape, and a triangular shape.

In the through hole 15 a of this embodiment, the opening diameter along the longitudinal axis direction of the tubular portion 15 is formed to be greater than or equal to the outer diameter length of the pipe connecting portion 14. The length of the through hole 15 a from the upper end of the inner surface of the tubular portion 15 to the upper end of the opening is substantially the same as the length from the upper end in the axial direction of the protruding pipe portion 13 of the joint 11 to the upper end of the pipe connecting portion 14. Is arranged. Furthermore, the opening diameter along the axial direction of the tubular portion 15 is, for example, a length obtained by combining the outer diameter a3 (see FIG. 2) of the pipe connecting portion 14 and the height h3 (see FIG. 2) from the bottom surface of the flange portion 12. More specifically, it is formed in a substantially elliptical shape with the axial direction of the tubular portion 15 as the major axis. The outer diameter a3 of the pipe connecting portion 14 is the cross-sectional length in the pipe axis direction of the pipe connecting portion 14 when the pipe connecting portion 14 protrudes at an elevation angle.
Thereby, when the tubular part 15 of this embodiment accommodates the protruding pipe part 13 and the pipe connecting part 14 of the joint 11 in the tubular part 15, the upper end of the protruding pipe part 13 is the inner surface of the tubular part 15. The pipe connecting portion 14 is positioned in the through hole 15a in a state of being positioned in the vicinity of the upper end of the inner surface including the state of being in contact with the upper end.

  The pedestal portion 16 of the present embodiment has a concave portion 16b that houses the flange portion 12 and has a similar shape to the flange portion 12 having the lower end opening 16a as an opening (see FIG. 5). The concave portion 16a of the pedestal portion 16 has a shape similar to that of the flange portion 12, that is, substantially the same as the disk shape that is the external shape of the flange portion 12, and can accommodate the entire flange portion 12. It is formed substantially the same or more. For this reason, the flange part 12 can be reliably accommodated in the recessed part 16a (refer FIG. 1). Note that the pedestal portion 16 is not limited to a similar shape to the flange portion 12 as long as the entire flange portion 12 can be accommodated, and the planar shape may be other shapes such as a rectangular shape or an elliptical shape.

In the present embodiment, the concave portion 16b of the pedestal portion 16 is provided with a plurality of projections 16c (in the present embodiment, three as an example) protruding toward the inside of the space on the inner wall surface (see FIGS. 4D and 5). The protrusion 16c is brought into a pressure contact state with the flange portion 12 of the joint 11 housed in the recess 16b, so that the pedestal portion 16 is not easily detached from the flange portion 12.
The joint cover 10 of the present embodiment is positioned in a plan view (top view) with the center of the long axis of the tubular portion 15 shifted (offset) from the center of the pedestal portion 16 in the long axis direction of the tubular portion 15. However, the inner surface length a1 (refer to FIG. 5) along the bottom surface of the pedestal portion 16, the outer surface length a2 (refer to FIG. 2) along the bottom surface of the flange portion 12 of the pipe connecting portion 14 and the protruding pipe portion 13, and Therefore, the joint cover 10 is designed to be the most compact.
That is, the offset amount of the tubular portion 15 is set such that the inner diameter of the concave portion 16a of the pedestal portion 16 is the inner diameter of the concave portion a4 (see FIG. 5). This corresponds to the difference from the position (see FIG. 5). In this embodiment, the projection length of the pipeline connecting portion 14 from the projection pipeline portion 13 is a5 (see FIG. 2), and the projection length a5 is to be exposed from the outer peripheral surface of the joint cover 10, It is offset so that at least the screwing portion (threaded portion) 14a within the protruding length a5 is exposed (see FIG. 1).
Further, the inner surface length a1 (see FIG. 5) of the tubular portion 15 is formed to be longer than the outer surface length a2 (see FIG. 2) of the pipe connecting portion 14 and the projecting pipe portion 13, but the inner surface length a1. And the outer surface length a2 are formed to be substantially the same (including a slightly larger length) that can accommodate the pipe connecting portion 14 and the protruding pipe portion 13, the tubular portion 15, that is, the joint cover 10 is The most compact can be formed. In this case, it can be installed without getting in the way even in a narrow place such as a toilet, and the fitting cover 10 can be improved.
In addition, the through hole 15a has an opening diameter along the axial direction of the tubular portion 15 such that the outer diameter a3 (see FIG. 2) of the pipe connecting portion 14 and the height h3 from the bottom surface of the flange portion 12 (see FIG. 2). The opening diameter along the axial direction of the tubular portion 15 is formed to be substantially the same (including a little larger) length than the total length of the outer diameter a3 and the height h3. In this case, the tubular portion 15, that is, the joint cover 10 can be formed most compactly.
In addition, the recess 16a of the pedestal portion 16 can accommodate the entire flange portion 12 and is formed to have substantially the same or larger size, but the recess 16a is substantially the same as the size of the flange portion 12 (slightly In the case of being formed in a larger size, the pedestal portion 16, that is, the joint cover 10 can be formed most compactly.
Further, when the annular rib 15d of the tubular portion 15 is formed to be substantially the same size (including a little larger) as the upper end portion of the protruding conduit portion 13, the tubular portion 15, that is, the joint cover 10 is most It can be formed compactly.

Next, a mounting procedure for mounting the joint cover 10 of the present embodiment having the above configuration to, for example, a joint 11 that functions as a toilet stop cock will be described.
As shown in FIGS. 6A to 6C, first, the joint cover 10 of the present embodiment is aligned so that the through hole 15 a faces the pipe connection portion 14 side, and protrudes on the floor surface F (on the surface). The joint 11 is put on the protruding pipe portion 13 (see FIG. 6A, arrow). As a result, the protruding pipe part 13 and the pipe connecting part 14 are inserted into the tubular part 15, and the pedestal part 16 is brought into contact with the upper surface of the flange part 12. The projecting end of the pipe connecting part 14 is positioned in the through hole 15a, and the entire projecting pipe part 13 and the pipe connecting part 14 can be accommodated and contained as they are (see FIG. 6B). At this time, the protruding duct portion 13 is located on the convex curved surface side that is the opposite side surface of the through hole 15a inside the tubular portion 15, and the operation portion 13a is displaced from the upper end opening 15b (FIG. 6B). reference).
The protruding pipe line portion 13 located on the convex curved surface side inside the tubular portion 15 is formed so that the joint cover 10 is formed most compactly, so that the protruding pipe line on the opposite side of the pipe connecting portion 14 of the joint 11. The outer peripheral surface (convex curved surface) side of the portion 13 comes into contact with the inner peripheral surface (convex curved surface) of the tubular portion 15. This contact state is made possible by the tubular portion 15 having a substantially elliptical shape with the center line direction of the through hole 15a as the major axis in plan view (top view) (see FIGS. 3 and 4). Become.

  Subsequently, the pedestal portion 16 on the upper surface of the flange portion 12 is moved laterally along the upper surface so as to penetrate the pipe connecting portion 14 from the through hole 15a (see FIG. 6B, arrow), and the concave portion of the pedestal portion 16 is obtained. The base 16 covers the entire surface of the flange 12 so that the flange 12 is positioned at 16a (see FIG. 6C). As a result, the projecting pipe line part 13 moves from the convex curved surface side inside the tubular part 15 to the through hole 15a side, and causes the entire screwed part 14a of the pipe line connecting part 14 to project from the through hole 15a. The upper end portion of the projecting duct portion 13 is located substantially directly below the rib 15d so that the portion 13a is located in the upper end opening 15b (see FIG. 6C). At this time, the pipe connection part 14 is located closer to the lower side of the through hole 15a, and there is a space above the pipe connection part 14 of the through hole 15a (see FIG. 6C).

  Subsequently, the joint cover 10 is pushed down substantially below (see the arrow in FIG. 6C) so that the flange portion 12 is inserted into the recess 16b of the pedestal portion 16, and substantially the entire flange portion 12 is stored in the recess 16b. To. As a result, the protruding pipe portion 13 inside the tubular portion 15 is in a fixed state in which the upper end portion is brought into contact with the inner opening end 15c and is sandwiched from the outside by the annular rib 15d, and is stored in the recess 16b. The protrusion 16c is brought into a press-contact state from the outside to the flange portion 12, and the pedestal portion 16 is fixed to the flange portion 12 (see FIG. 1). At this time, the pipe connection part 14 is located in the approximate center of the through-hole 15a, and the flange part 12 is entirely covered with the base part 16 (refer FIG. 1).

As a result, it protrudes on the floor surface F (on the surface), protrudes on the side surface of the protruding conduit portion 13 and the protruding conduit portion 13 having the flange portion 12 fixed to the floor surface F (surface). A joint cover 10 is attached to a joint 11 having a pipe connection part 14 communicating with the pipe part 13, and the joint 11 is covered with the joint cover 10 except for the pipe connection part 14. And the joint cover 10 are combined (see FIG. 1).
After the joint cover 10 is attached to the joint 11, a water supply hose (not shown) is screwed into the threaded portion 14 a of the pipe connecting portion 14, which is substantially entirely protruded from the through hole 15 a, using a nut, for example. By doing so, the pipe (not shown) arranged under the floor and the water storage tank (not shown) of the toilet unit are connected and communicated via the joint 11 to which the joint cover 10 is attached.

As described above, the joint cover 10 according to the present embodiment has a complicated shape made of a cylindrical member that intersects with the disk member, and the joint 11 that protrudes on the floor surface F (on the surface) is connected to one joint. The cover 10 can be attached to the joint 11 only by moving the joint 11 two times in the lateral direction and the downward direction after being put on the joint 11, and almost all of the joint 11 can be covered with a shape substantially matched to the joint shape. .
Therefore, the joint cover 10 according to the present embodiment has two parts as well as a conventional cover that covers the flange portion, in addition to the cover that covers the flange portion. The design is not preferable, the mounting is not troublesome, and the number of parts in the mounting operation is not increased with a small number of parts, so that most of the joint 11 can be covered.

Moreover, by attaching the joint cover 10 of the present embodiment to the joint 11, for example, it protrudes on the floor surface F (on the surface) on which the toilet unit is installed, and the floor surface F is easily visible to the toilet user. Since the arranged concave and convex joint 11 can be covered with a smooth curved surface shape, a design effect can be obtained and the appearance can be improved, and for example, when the cleaning tool is hit, it is scratched. Can be prevented. Further, the surface of the joint 11 is mainly made of a cast surface (roughened) and is difficult to wipe off during cleaning or the like. However, the presence of the joint cover 10 makes it difficult to get dirt and further improves the cleanability.
Note that, regardless of the joint 11 of the present embodiment, a general-purpose joint having various shapes and sizes can correspond to the pipe line length h2, the external length a2, the height h3 from the bottom surface, and the like. If the inner surface height h1 of the tubular portion 15, the inner surface length a1 along the bottom surface of the pedestal portion 16, the length from the upper end of the inner surface of the tubular portion 15 of the through hole 15 a to the upper end of the opening, etc. are adjusted, the corresponding joint cover 10 can be formed.

Further, if the joint cover 10 is formed of a flexible member such as a rubber member, a water supply hose connected to and communicated with the joint 11 is passed through the through hole 15a of the joint cover 10 in advance, and the water supply hose is connected to the joint 11. It is also possible to attach the joint cover 10 to the joint 11 from above the protruding pipe portion 13 by using flexibility after connecting / communicating to the pipe connecting portion 14.
Further, in this embodiment, the pipe connecting portion 14 is passed through the through hole 15a. However, the lower portion of the through hole 15a is cut out including the pedestal portion 16 as it is. It is good also as a through-hole which has a direction U-shaped opening surface. In this case, the pipe connection part 14 can be taken out from the through hole 15a without shifting the joint cover 10 covering the joint 11 to the side, and the tubular part 15 is not offset. good. Accordingly, the joint cover 10 can be attached to the joint 11 even after the water supply hose is connected to and communicated with the pipe connecting portion 14 of the joint 11.
