Description

[Technical field]

[0001] The present invention relates to a faucet. [Background technology]

[0002] Patent Document 1 describes a connection structure for a water faucet. As shown in Fig. 12, the faucet 100 has a wall-mounted stay 101 that is attached to a wall surface (not shown), and a faucet main body 102 that is attached to the wall-mounted stay 101. The faucet main body 102 has a faucet body 103 and a main body stay 104 that is attached to the faucet body 103. The main body stay 104 is attached to the wall-mounted stay 101, whereby the faucet 100 is fixed to the wall surface.

[0003] 12, the wall surface fixing stay 101 has a pair of left and right through-holes 101a. A water supply pipe K1 and a hot water supply pipe K2 are inserted into these through-holes 101a from the rear side of the wall surface.

[0004] 13, the wall surface fixing stay 101 has hook-shaped projections 105 protruding forward near the upper end on both the left and right sides. Also, a screw hole 101b is formed above the projections 105. The projections 105 have a base 105a protruding upward, a receiving portion 105b bent forward from the base 105a, and a fall prevention portion 105c bent further upward from the tip of the receiving portion 105b.

[0005] 13, the main body stay 104 has a pair of elongated holes 104a on both the left and right sides, and a pair of screw insertion holes 104b above the elongated holes 104a. When attaching the faucet main body 102 to the wall fixing stay 101, the long hole 104a of the main body stay 104 is engaged with the protrusion 105 of the wall fixing stay 101. Furthermore, a screw 106 is inserted into the screw insertion hole 104b of the main body stay 104, and the screw 106 is attached to the screw hole 101b of the wall fixing stay 101. This temporarily fixes the main body stay 104 to the wall fixing stay 101. In this state, the faucet body 103 of the faucet main body 102 is connected to the water supply pipe K1 and the hot water supply pipe K2. By temporarily fixing the main body stay 104 to the wall fixing stay 101 in advance, it is possible to prevent the faucet main body 102 from falling off when connecting the faucet body 103 to the water supply pipe K1 and the hot water supply pipe K2.

[0006] [Patent Document 1] JP 2006-328674 A Summary of the Invention [Problem to be solved by the invention]

[0007] Incidentally, in the faucet of Patent Document 1, the protrusion 105 of the wall-fixed stay 101 has a fall-prevention portion 105c that is bent upward. When engaging the long hole 104a of the main body stay 104 with this protrusion 105, the long hole 104a of the main body stay 104 needs to be engaged with the protrusion 105 of the wall-fixed stay 101 from a position slightly above. In other words, it is necessary to lift the faucet main body 102 to a slightly higher position relative to the wall-fixed stay 101, and then move the faucet main body 102 up and down so that the long hole 104a engages with the protrusion 105. This causes a problem in that the task of attaching the faucet main body 102 to the wall-fixed stay 101 is time-consuming. [Means for solving the problem]

[0008] The faucet of embodiment 1 is a faucet having a wall-fixing stay that is attached to a wall surface and a faucet body that is attached to the wall-fixing stay, wherein the wall-fixing stay and the faucet body have engaging portions that engage with each other in a convex-concave relationship, and the engaging portion is formed by engagement between a slit provided in a vertical wall of the wall-fixing stay and a horizontal wall of the faucet body, or by engagement between a horizontal wall of the wall-fixing stay and a slit provided in a vertical wall of the faucet body.

[0009] With this configuration, there is no need to lift the faucet body and move it up and down when engaging the horizontal wall with the slit in the vertical wall, so the work of attaching the faucet body to the wall-mounted stay can be carried out efficiently.

[0010] In the faucet of the second aspect, the slit extends horizontally. With this configuration, the faucet body can be engaged with the wall-mounted stay by moving the faucet body horizontally along the slit. This makes it possible to more efficiently attach the faucet body to the wall-mounted stay.

[0011] In a third aspect of the faucet of the first or second aspect, the faucet main body has a faucet body and a main body stay attached to the faucet body, and the engagement portion of the faucet main body is provided on the main body stay. With this configuration, the faucet main body can be attached to the wall surface fixing stay by engaging the wall surface fixing stay with the main body stay.

[0012] Aspect 4 is the faucet according to any one of Aspects 1 to 3, wherein the wall-fixed stay has a support portion that supports the faucet body from below while being in surface contact with the faucet body. With this configuration, the engagement between the wall-fixed stay and the faucet body at the engagement portion can be made more stable.

[0013] A fifth aspect is the faucet of the fourth aspect, wherein the wall-fixed stay has a pair of the engaging portions and a pair of the support portions at both left and right ends. With this configuration, the engagement between the wall-fixed stay and the faucet body at the engaging portions can be made more stable. Effect of the Invention

[0014] According to the faucet of the present invention, the work of attaching the faucet body to the wall fixing stay can be carried out efficiently. [Brief description of the drawings]

[0049] The front cover engaging member 12 has insertion holes (not shown) for mounting to a wall surface W at the longitudinal center and lower sides of both ends of the horizontal wall 12a and on the left-right inside of the lower end of the vertical wall 12b.

[0050] As shown in FIG. 2, the front cover engagement member 12 has a U-shaped periphery that is open downward and is defined by a horizontal wall 12a and a pair of vertical walls 12b. When the front cover 50 described later is attached to the main body stay 80, the rear end of the front cover 50 engages with the U-shaped peripheral edge of the front cover engagement member 12, thereby sealing the gap between the rear end of the front cover 50 and the wall surface W.

[0051] <Top cover> As shown in Fig. 2, the faucet 10 has a top cover 40 connected to a top cover stay 90. The top cover 40 has a top wall 41 that is a rectangular plate that is long in the left-right direction. The top cover 40 has hanging walls 42 that extend downward from each side of the top wall 41 along the thickness direction of the top wall 41. The hanging walls extending from the front end, rear end, right end, and left end of the top wall 41 are referred to as front hanging wall 42a, rear hanging wall 42b, right hanging wall 42c, and left hanging wall 42d, respectively.

[0052] The top wall 41 has four through holes 43 arranged along the left-right direction. These through holes 43 are used to insert the temperature adjustment handle 24, the flow rate adjustment handle 25, the faucet button 26, and the shower button 27 therethrough.

[0053] 9 and 10, the top cover 40 has a plurality of accommodating portions 45 for accommodating nuts (not shown) on the back surface of the top wall 41. A top cover stay 90 and a locking member 30 are attached to the top cover 40 by screwing a screw into the nut accommodated in the accommodating portion 45.

[0054] <Front cover> As shown in Fig. 2, the faucet 10 has a front cover 50 connected to the main body stay 80. The front cover 50 has a front wall 51 that is a rectangular plate that is long in the left-right direction. The front cover 50 has side walls 52 that extend rearward from both left and right ends of the front wall 51. The front cover 50 has a connecting wall 53 that connects the upper ends of the side walls 52 at the rear ends.

[0055] The front cover 50 has a horizontal wall 54 that protrudes further inward from the inner side of the side wall 52. The horizontal wall 54 has insertion holes 54a through which screws for attaching the front cover 50 to the main body stay 80 are inserted.

[0056] The front wall 51 of the front cover 50 has a notch 51a cut downward at the upper end on the right side in the left-right direction. This notch 51a is used for inserting the lever 34 of the locking member 30 from the inside to the outside of the front cover 50. By inserting the lever 34 through the notch 51a, it becomes possible to operate the lever 34 from the front side of the front cover 50.

[0057] <Undercover> As shown in Fig. 2, the faucet 10 has an undercover 55 connected to the main body stay 80. The undercover 55 has a rectangular plate-shaped bottom wall 56 that is long in the left-right direction. The undercover 55 has a notch 57 on the front side in the center in the left-right direction. This notch 57 is used to insert the discharge pipe 22 of the faucet main body 20.

[0058] The undercover 55 has three through holes 56a aligned in the left-right direction on the rear side in the front-rear direction. Of the three through holes 56a, the two through holes 56a on the left and right sides are used to expose the stopcock 21a (see FIG. 5) of the socket 21. Of the three through holes 56a, the central through hole 56a is used to insert the hose pipe 23.

[0059] The undercover 55 has a pair of insertion holes 56b on both the left and right sides sandwiching the notch 57. In addition, a pair of insertion holes 56b is also provided on both the left and right sides sandwiching the three through holes 56a. These insertion holes 56b are elongated holes that are long in the front-rear direction, and are used for inserting screws when attaching the undercover 55 to the main body stay 80.

[0060] The materials for the top cover 40, front cover 50, and under cover 55 as the faucet covers are not particularly limited, but if they are made of resin, it is preferable because the weight of the faucet 10 can be reduced.

[0061] The faucet 10 is made up of the above-mentioned components. There is no particular restriction on the procedure for assembling the components. After assembling the components, the components can be assembled by screwing a screw into the screw hole of each component. Alternatively, the components can be assembled by inserting a screw into the insertion hole of each component and then screwing the screw into the screw hole of another component.

[0062] <Action and Effects> The operation of this embodiment will be described. 3 and 5, when fixing the faucet 10 to a wall W, a wall fixing stay 60 is attached to the wall W in advance. Then, the faucet body 11 is connected to the water supply pipe K1 and the hot water supply pipe K2 on the wall W via the socket 21. Furthermore, a main body stay 80 is attached to the wall fixing stay 60.

[0063] 3 shows only the faucet body 11 and the body stay 80 as the faucet main body 20, but in addition, a top cover 40, a front cover 50, and an under cover 55 may be attached as faucet covers. The under cover 55 may be removed so that an operator can perform work from below the faucet main body 20.

[0064] This will be explained in further detail below. As shown in Fig. 7, when the faucet body 11 is connected to the water supply pipe K1 and the hot water supply pipe K2 on the wall surface W, the main body stay 80 is moved horizontally rearward along the front-to-rear direction. Note that Fig. 7 shows only the main body stay 80 of the faucet body 20, and omits the faucet body 11. The wall surface W, the water supply pipe K1, and the hot water supply pipe K2 are also omitted.

[0065] 7 and 8, the main body stay 80 is moved horizontally backward so that the extension portion 82 of the main body stay 80 abuts on the third bent wall 63 of the wall surface fixing stay 60. Then, the screw hole 82c (see FIG. 6) of the extension portion 82 is positioned so as to overlap with the insertion hole 63a (see FIG. 6) of the third bent wall 63.

[0066] 8, the rear end of the extending portion 82 of the main body stay 80 is inserted into the slit 65 of the vertical wall of the wall-fixing stay 60 at a position where the screw hole 82c of the extending portion 82 overlaps with the insertion hole 63a of the third bent wall 63. In other words, the rear end of the extending portion 82 of the main body stay 80 engages with the slit 65 of the wall-fixing stay 60. In this state, the faucet body 11 is connected to the water supply pipe K1 and the hot water supply pipe K2 on the wall W via the socket 21.

[0067] Furthermore, the main body stay 80 is attached to the wall surface fixing stay 60 by inserting the screw 15 from below the insertion hole 63a of the third bent wall 63 and screwing it into the screw hole 82c of the extension portion 82.

[0068] By the above steps, the faucet 10 is fixed to the wall surface W. When removing the faucet 10 from the wall surface W, the above steps are performed in reverse order. The rear end of the extension portion 82 of the main body stay 80 and the slit 65 in the vertical wall of the wall-fixing stay 60 function as an engagement portion that engages with each other in a convex-concave relationship.

[0069] 7 and 8, the rear end of the extension 82 of the main body stay 80 engages with the slit 65 of the wall fixing stay 60, thereby preventing the faucet main body 20 from falling off during the installation of the faucet 10. That is, the main body stay 80 can be prevented from falling off the wall fixing stay 60 during the operation of connecting the faucet body 11 to the water supply pipe K1 and the hot water supply pipe K2 on the wall W. In addition, the main body stay 80 can also be prevented from falling off the wall fixing stay 60 during the operation of removing the faucet body 11 from the water supply pipe K1 and the hot water supply pipe K2 on the wall W.

[0070] 7 and 8, when the extending portion 82 of the main body stay 80 is in contact with the third bent wall 63 of the wall-fixed stay 60, the third bent wall 63 supports the extending portion 82 from below while being in surface contact with the extending portion 82. That is, the third bent wall 63 functions as a support portion that supports the faucet main body 20 from below while being in surface contact with the faucet main body 20. Since the support portion can support the main body stay 80 in a more stable state, it is possible to more suitably prevent the main body stay 80 from falling off the wall-fixed stay 60.

[0071] The effects of this embodiment will be described. (1) The wall-fixing stay 60 and the main body stay 80 have engaging portions that engage with each other in a convex-concave relationship, and the engaging portions are formed by the engagement between a slit 65 provided in the vertical wall of the wall-fixing stay 60 and an extension portion 82 of a horizontal wall 81 of the main body stay 80.

[0072] By moving the main body stay 80 horizontally backward, the extension 82 of the horizontal wall 81 can be engaged with the slit 65 of the vertical wall of the wall-fixed stay 60. When engaging the extension 82 of the horizontal wall 81 with the slit 65 of the vertical wall, there is no need to lift the faucet main body 20 and move it up and down. Generally, the faucet body 11 is made of metal and therefore tends to be heavy. Therefore, by not moving the faucet main body 20 with the faucet body 11 up and down, the work of attaching the faucet main body 20 to the wall-fixed stay 60 can be performed efficiently.

[0073] (2) The engaging portion of the faucet main body 20 is provided on the main body stay 80. That is, the extending portion 82 of the side wall 81 of the main body stay 80 functions as the engaging portion. Therefore, it is easier to form the engaging portion compared to an embodiment in which the engaging portion is provided on the faucet body 11.

[0074] (3) The wall-fixed stay 60 has a support portion that supports the main body stay 80 from below while being in surface contact with the main body stay 80. Therefore, the main body stay 80 can be supported in a more stable state by the support portion, and therefore, the main body stay 80 can be more suitably prevented from falling off the wall-fixed stay 60.

[0075] (4) The wall-fixed stay 60 has a pair of engaging portions and a pair of supporting portions at both left and right ends thereof. This makes it possible to support the main body stay 80 in a more stable state and more effectively prevent the main body stay 80 from falling off the wall-fixed stay 60.

[0076] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0077] In the present embodiment, the rear end of the extension portion 82 of the main body stay 80 and the slit 65 in the vertical wall of the wall-fixed stay 60 function as an engagement portion that engages with each other in a convex-concave relationship, but this is not limited to this. The engagement portion may be configured by the engagement of a horizontal wall of the wall-fixed stay 60 and a slit provided in the vertical wall of the main body stay 80.

[0078] As shown in Fig. 11, for example, the wall-fixed stay 60 may have horizontal walls 66 bent forward and extending along the left-right and front-rear directions at the upper ends of both the left and right sides of the vertical wall 64. The main body stay 80 may have a vertical wall 87 extending along the up-down and front-rear directions at an extension 82 of the horizontal wall 81. This vertical wall 87 may have a slit 87a extending horizontally from the rear end toward the front. The engagement portion may be formed by engagement between the horizontal wall 66 of the wall-fixed stay 60 and the slit 87a of the vertical wall 87 of the main body stay 80.

[0079] In this embodiment, the slit 65 provided in the vertical wall of the wall-fixed stay 60 extends along the horizontal direction, but is not limited to this. It may extend along a direction slightly inclined with respect to the horizontal direction. For example, if the slit 65 extends diagonally upward toward the front, the engagement between the slit 65 and the extension portion 82 of the horizontal wall 81 of the main body stay 80 will be less likely to be released.

[0080] In the present embodiment, the extension 82 of the side wall 81 of the main body stay 80 functions as an engagement portion of the faucet main body 20, but this is not limited to the embodiment. The engagement portion of the faucet main body 20 may be provided on the faucet body 11 or the faucet cover. In other words, a side wall may be provided on the faucet body 11 or the faucet cover, and this side wall may be configured to engage with the slit 65 of the vertical wall of the wall-mounted stay 60.

[0081] In the present embodiment, the wall-fixed stay 60 has the slits 65 as a pair of engaging portions and the third bent walls 63 as a pair of supporting portions at both ends in the left-right direction, but is not limited to this aspect. The wall-fixed stay 60 may have the slits 65 as an engaging portion and the third bent wall 63 as a supporting portion only on one side in the left-right direction. The wall-fixed stay 60 may have the slits 65 as an engaging portion only on one side in the left-right direction and the third bent wall 63 as a supporting portion only on the other side in the left-right direction. In an aspect in which the third bent wall 63 is provided only on the other side in the left-right direction, the extension portion 82 of the main stay 80 abuts against the upper end portion of the second bent wall 62 on one side in the left-right direction of the wall-fixed stay 60 that does not have the third bent wall 63.

[0082] The third bent wall 63 may be omitted on both the left and right sides. In this case, the upper end of the second bent wall 62 may extend along the lower side of the slit 65 and support the extending portion 82 from below while being in line contact with the extending portion 82. In an embodiment in which the third bent wall 63 is omitted, a screw hole for attaching the main body stay 80 may be separately provided in the vertical wall 64 of the wall surface fixing stay 60, and the screw 15 may be fixed into this screw hole.

[0083] In the present embodiment, the length of the second bent wall 62 along the front-rear direction is longer than the length of the first bent wall 61 along the same direction, but this is not limited to this. The length of the second bent wall 62 along the front-rear direction may be equal to the length of the first bent wall 61 along the same direction, or may be shorter than the length of the first bent wall 61.

[0084] In this embodiment, the rear end of the extension portion 82 of the main body stay 80 extends linearly in the left-right direction, but is not limited to this. A slit extending forward in the front-rear direction may be formed in the rear end of the extension portion 82 of the main body stay 80. This slit may be configured to engage with the slit 65 of the wall-fixing stay 60. In other words, the slits may be configured to engage with each other.

[0085] In the present embodiment, the slit 65 of the wall-fixing stay 60 is provided between the first curved wall 61 and the second curved wall 62, but the present invention is not limited to this. For example, the vertical wall 64 of the wall-fixing stay 60 may be configured to be thick, and a slit may be formed along the thickness direction of the vertical wall 64. [Explanation of symbols]
