Description

The present invention relates to, for example, an eccentric pipe cover for covering an eccentric pipe connecting a hot water mixing faucet and a supply pipe on the primary side, and a hot water mixing faucet provided with the eccentric pipe cover.

If the eccentric pipe that connects the hot water mixing faucet and the hot water supply pipe on the primary side (upstream side) of the faucet is exposed, there is a risk of burns to a person who comes into contact with the eccentric pipe that has become hot due to the hot water flowing inside. Therefore, conventionally, the eccentric tube is covered with a cover (see Patent Document 1).

Japanese Patent No. 3107355

However, the above-mentioned conventional cover is only locked to the eccentric tube by the elastic leg, and if the elastic leg is relatively easily deformed, the cover will come off from the eccentric tube by some momentum and eccentricity. The tube may be exposed and the prevention of burns may be incomplete. On the contrary, if the elastic leg is relatively hard to be deformed, a large force is required to attach the cover to the eccentric tube, and the wearability is lowered.

The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide an eccentric tube cover having a simple structure and excellent detachability and safety, and a hot water mixing faucet provided with the eccentric tube cover. It is in.

In order to achieve the above object, the eccentric tube cover according to the present invention is a hollow eccentric tube cover whose lower part is open, and the front wall is provided with a snap-fit portion which is open downward, and the back wall is provided with a snap-fit portion. A hook portion that projects laterally and a notch portion that extends from the lower end of the back wall and the tip side of the hook portion to the upper side of the hook portion are provided (claim 1).

On the other hand, in order to achieve the above object, the hot water mixing faucet according to the present invention includes the eccentric tube cover according to claim 1 (claim 2).

According to the present invention, an eccentric tube cover having a simple structure but excellent detachability and safety, and a hot water mixing faucet provided with the eccentric tube cover can be obtained.

That is, in the eccentric tube cover of the invention according to each claim of the present application, the mounting is completed only by performing the operation of locking the hook portion and the operation of locking the snap fit portion, and the mounting property is improved. Can be done. Moreover, since the direction in which the hook portion is locked and the direction in which the snap fit portion is locked are different, the hook portion can be locked and snap-fitted regardless of the direction in which the force is applied to the eccentric tube cover. The locking of the part is not released at once, and the safety can be improved accordingly. Further, both the snap-fit portion and the hook portion provided on the eccentric tube cover of the present invention may have a simple shape, and the structure can be simplified.

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 1 (B) and 2 (A) to (H) is located on the primary side (upstream side) of the two eccentric pipes 3 connected to the hot water mixing faucet 2. This is for covering the eccentric pipe 3 to which the hot water supply pipe (not shown) is connected (see FIGS. 3A to 3J).

Specifically, the eccentric tube cover 1 has a substantially box shape that is hollow and has an open lower portion, the front wall 4 is provided with a snap-fit portion 5 that is open downward, and the back wall 6 is provided at the lower end. A hook portion 7 that projects laterally and a notch portion 8 that extends from the lower end of the back wall 6 and the front 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 protrusions 4A and 4B protruding forward on the left and right, and a snap-fit portion 5 is provided on the front surface of one of the protrusions 4B. The snap-fit portion 5 is formed in a C-shape (superior arc shape) that is open downward, and the entire upper portion is integrated with the upper edge of the front wall 4 (protruding portion 4B), while the left and right snap-fit portions 5 are integrated. The locking portion 9 is configured to be separated from other portions of the front wall 4 so as to be easily elastically deformed.

In the back wall 6 of this example, the portion corresponding to the back surface side of the protruding portion 4A protrudes rearward from the other portions, and the hook portion 7 is provided in this protruding portion.

In order to cover the eccentric tube 3 with the eccentric tube cover 1 having the above configuration, the procedure shown in FIGS. 4 (A) to 4 (D) may be performed. In FIGS. 4A to 4D, the configurations of the eccentric tube cover 1 and the eccentric tube 3 are shown in an extremely simplified manner.

That is, first, as shown in FIG. 4A, the upstream portion 3A of the eccentric tube 3 (this upstream portion may be a part of the eccentric tube 3 or is connected to the upstream side of the eccentric tube 3). The eccentric pipe cover 1 is laterally oriented with respect to a member such as a pipe (the side here refers to a direction substantially perpendicular to the axial direction of the upstream portion of the eccentric pipe 3). It is used in the sense of excluding the front and the rear, and may be approached from above or below, for example) so that the upstream portion 3A of the eccentric tube 3 extends inside and outside the notch portion 8 (FIG. 4 (B)). reference).

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

Further, when the eccentric tube cover 1 is tilted (upstream portion of the eccentric tube 3) while the upstream portion 3A of the eccentric tube 3 is brought into contact with the peripheral edge of the notch portion 8 (while being pulled upward in the example shown in FIG. 4C). The snap-fit portion 5 is connected to the downstream portion 3B of the eccentric tube 3 (this downstream portion may be a part of the eccentric tube 3 or is connected to the downstream side of the eccentric tube 3). It is locked to a member such as a hot water mixing faucet 1), which completes the attachment of the eccentric tube cover 1 (see FIG. 4 (D)). If you want to remove the eccentric tube cover 1, you can reverse the above procedure.

In the eccentric tube cover 1 of this example configured as described above, the mounting is completed only by performing the operation of locking the hook portion 7 and the operation of locking the snap fit portion 5, and the mounting property is improved. Can be enhanced. Moreover, since the direction in which the hook portion 7 is locked with respect to the upstream portion 3A of the eccentric tube 3 and the direction in which the snap-fit portion 5 is locked with respect to the downstream portion 3B of the eccentric tube 3 are different, the eccentric tube cover. Regardless of the direction in which the 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 once, and the safety can be improved accordingly. Further, both the snap-fit portion 5 and the hook portion 7 provided on the eccentric tube cover 1 of this example may have a simple shape, and the structure can be simplified.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be variously modified and implemented without departing from the gist of the present invention. For example, the following modification examples can be given.

In the above embodiment, since the eccentric tube 3 is provided with the operation unit 10 for adjusting the flow rate (see FIG. 3C), the opening 11 for exposing the operation unit 10 is projected from the front wall 4. Although it is provided in the portion 4A (see FIG. 1A), the position and shape 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 from each other in the left-right direction in the front view, and the hook portion 7 projects toward the snap-fit portion 5 in the left-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, and for example, the hook portion. 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 water mixing faucet 2, the eccentric pipe 3 to cover the eccentric pipe 3 to which the hot water supply pipe (not shown) is connected to the primary side (upstream side) thereof. 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 to the primary side thereof.

Needless to say, the above modified examples may be combined as appropriate.
