(A)-(D) are explanatory drawings which show roughly the mounting method of the said eccentric pipe cover.

  Embodiments of the present invention will be described below with reference to the drawings.

  The eccentric pipe cover 1 shown in FIGS. 1 (A) and (B) and FIGS. 2 (A) to (H) is located on the primary side (upstream side) of the two eccentric pipes 3 connected to the hot and cold water mixing faucet 2. It is for covering the eccentric pipe 3 to which hot water supply piping (not shown) is connected (refer FIG. 3 (A)-(J)).

  Specifically, the eccentric tube cover 1 has a hollow, substantially box-like shape with an open lower side, the front wall 4 is provided with a snap fit portion 5 opened downward, and the rear wall 6 has a lower end at the lower end. A hook portion 7 which protrudes in the lateral direction and a notch 8 which extends from the lower end of the back wall 6 and the tip side of the hook portion 7 to the upper side of the hook portion 7 are provided.

  The front wall 4 of this example has the left and right projecting portions 4A and 4B projecting forward, and the snap fit portion 5 is provided on the front surface of one of the projecting portions 4B. Then, the snap fit portion 5 is formed in a C shape (a major arc shape) opened downward, and the entire upper portion is integrated with the upper edge of the front wall 4 (protruding portion 4B). The locking portion 9 is configured to be easily elastically deformed apart from the other portion of the front wall 4.

  In the back wall 6 of this example, a portion corresponding to the back side of the protruding portion 4A protrudes more rearward than the other portions, and a hook portion 7 is provided on this protruding portion.

  In order to cover the eccentric pipe 3 with the eccentric pipe cover 1 configured as described above, the procedure shown in FIGS. 4 (A) to 4 (D) may be taken. In FIGS. 4A to 4D, the configurations of the eccentric pipe cover 1 and the eccentric pipe 3 are extremely simplified.

  That is, first, as shown in FIG. 4A, the upstream portion 3A of the eccentric tube 3 (this upstream portion may be part of the eccentric tube 3 or is connected to the upstream side of the eccentric tube 3 The side of the eccentric pipe cover 1 with respect to the eccentric pipe cover 1 may be a part of a member such as piping (here, the side indicates a direction substantially perpendicular to the axial direction of the upstream portion of the eccentric pipe 3) It is used in the meaning except the front and the back, for example, it makes it approach from the upper or lower), and makes the state where the upstream part 3A of the eccentric tube 3 extends over the inside and outside of the notch 8 (FIG. 4 (B) reference).

  Subsequently, as shown in FIGS. 4B and 4C, the upstream portion 3A of the eccentric tube 3 is directly above the hook portion 7 in the state shown in the back side of the notch 8 (FIG. 1B). Slide the eccentric tube cover 1 so that it is located in. As a result, the hook portion 7 is locked to the upstream portion 3A of the eccentric pipe 3.

  Furthermore, when the eccentric tube cover 1 is turned down while bringing the upstream portion 3A of the eccentric tube 3 into contact with the peripheral edge of the notch 8 (while pulling up to the upper side in the example shown in FIG. 4C) (upstream portion of the eccentric tube 3) The snap fit portion 5 is a downstream portion 3B of the eccentric tube 3 (this downstream portion may be part of the eccentric tube 3 or connected to the downstream side of the eccentric tube 3). Of the mixing faucet 1 etc.), whereby the mounting of the eccentric pipe cover 1 is completed (see FIG. 4 (D)). In addition, what is necessary is just to follow the above-mentioned reverse procedure, when you want to remove the eccentric pipe cover 1.

  In the eccentric tube cover 1 of the present example configured as described above, the mounting is completed simply by performing the operation of locking the hook portion 7 and the operation of locking the snap fit portion 5. It can be enhanced. Moreover, since the direction in which the hook portion 7 is locked to the upstream portion 3A of the eccentric tube 3 is different from the direction in which the snap fit portion 5 is locked to the downstream portion 3B of the eccentric tube 3, the eccentric tube cover No matter from which direction a force is applied to 1, the locking of the hook portion 7 and the locking of the snap fit portion 5 are not released at a stretch, and the safety can be enhanced accordingly. Furthermore, both the snap fit portion 5 and the hook portion 7 provided in the eccentric pipe cover 1 of the present embodiment may have a simple shape, and the structure can be simplified.

  The present invention is not limited to the above embodiment, and it is needless to say that the present invention can be modified in various ways without departing from the scope of the present invention. For example, the following modifications can be mentioned.

  In the above embodiment, since the eccentric pipe 3 is provided with the operation part 10 (see FIG. 3C) for flow rate adjustment, the opening 11 for exposing the operation part 10 is a protrusion of the front wall 4 Although provided in the portion 4A (see FIG. 1A), the position, the shape, and the like of the opening 11 can be appropriately changed according to the configuration of the operation portion 10.

  In the above embodiment, the snap fit portion 5 and the hook portion 7 are separated in the left and right direction in a front view, and the hook portion 7 protrudes toward the snap fit portion 5 in this left and right direction. The portion 7 may protrude in a direction away from the snap fit portion 5.

  In the above embodiment, the hook portion 7 is locked to the upstream portion 3A of the eccentric tube 3 and the snap fit portion 5 is locked to the downstream portion 3B of the eccentric tube 3. However, the present invention is not limited to this. 7 may be locked to the downstream portion 3B of the eccentric tube 3 and the snap fit portion 5 may be locked to the upstream portion 3A of the eccentric tube 3.

  In the above embodiment, of the two eccentric pipes 3 connected to the hot and cold water mixing faucet 2, the eccentric pipe 3 is covered to cover the eccentric pipe 3 to which the hot water supply pipe (not shown) is connected on its primary side (upstream side). Although the cover 1 is used, the eccentric pipe cover 1 may be used to cover the eccentric pipe 3 to which the water supply pipe is connected on the primary side.

  Needless to say, the above-described modifications may be combined as appropriate.
