[0002]
[Prior art]
Conventionally, a shower head (water discharge head) that can be drawn out together with a flexible hose has a water discharge portion provided in a state of protruding on a mounting base such as a counter, and water provided in a state of protruding on the mounting base. 2. Description of the Related Art Shower faucet equipment having a stopper main body and having a hose connected to a shower head extending in a lower space of a mounting base and connected to the faucet main body is known.
[0003]
FIG. 4 shows an example.
In this figure, reference numeral 200 denotes a water discharge portion in the shower faucet equipment, which is provided in a state of standing on the upper surface of a counter 202 as an attachment base.
The water discharger 200 includes a shower head 204, a curved tubular holder 206 that holds the shower head 204, and a pedestal unit 214 for attaching them to the counter 202.
[0004]
The shower head 204 has a water discharge port 210 on the lower surface of the tip thereof, and performs rectified water discharge or shower water discharge from the water discharge port 210, and further on the front surface thereof from rectified water discharge to shower water discharge or vice versa. And an operation unit 212 for performing switching operation.
A flexible hose 208 is connected to the shower head 204, and the shower head 204 can be pulled out from the holder 206 together with the hose 208.
[0005]
The pedestal unit 214 is screwed into the upper surface of the counter 202, that is, the pedestal 216 seated on the mounting surface 218, the cylindrical member 220 inserted through the mounting hole 219 downward from the pedestal 216, and the external thread on the outer peripheral surface of the cylindrical member 220. The pedestal 216 and the tightening nut 222 are fixed to the counter 202 in a state of sandwiching the counter 202 from above and below through the triangular packing 224.
[0006]
The water discharger 200 has a slide tube 226 extending downward from the holder 206.
The slide tube 226 is a member that moves up and down together with the holder 206, and is inserted into the cylindrical member 220 of the pedestal unit 214 so as to slide up and down as shown in FIG.
Further, the hose 208 is movably inserted into the slide tube 226.
[0007]
227 is a faucet body attached to the counter 202 by a tightening nut 222 in a sealing state by a triangular packing 224 at a position separated from the water discharger 200 and in the attachment hole 228, and has a mixing part 230 and a handle 232. Yes.
[0008]
A supply pipe 234 supplies water and hot water to the faucet body 227. Water and hot water supplied through the supply pipe 234 are mixed by the faucet body 227 and flow out through the outflow pipe 236. Then, the mixed water is guided to the shower head 204 through a hose 208 connected to the outflow pipe 236.
[0009]
By the way, in order to make the water that has fallen on the upper surface of the counter 202, particularly in the vicinity of the water discharger 200, flow down to a water tank such as a wash bowl or a sink, a part of the counter 202 is inclined, and the water discharger 200 is made to the inclined part. Installation is done.
In this case, the water discharger 200 is attached in a state of being relatively inclined with respect to the attachment surface 218 of the counter 202. An example of a mounting structure for this purpose is shown in FIG.
[0010]
Here, a spacer 238 is provided on the back side of the counter 202, and the seating surface 242 of the spacer 238 and the seating surface 240 of the pedestal 216 correspond to the inclination angle of the counter 202 with respect to the axial centers of the spacer 238 and the pedestal 216, respectively. In the state where the inclined surfaces are inclined and the seating surfaces 242 and 240 are seated on the back surface 244 and the mounting surface 218 of the counter 202, the counter 202 is placed on both the front and back sides via the spacer 238 by the base 216 and the tightening nut 222. The pedestal unit 214 is attached, that is, the water discharger 200 is attached so as to be sandwiched therebetween.
[0011]
[Problems to be solved by the invention]
However, when the water discharger 200 is mounted in this manner, the tightening force between the external thread on the outer peripheral surface of the cylindrical member 220 and the tightening nut 222 does not act on the mounting surface 218 of the counter 202 in the direction perpendicular thereto. It will work in a relatively inclined direction.
For this reason, due to the tightening force, that is, due to the component force of the tightening force, a force acts to slide the base 216 and the spacer 238 in the direction indicated by the arrow in the drawing.
[0012]
Here, since the base 216 is pressed against the mounting surface 218 via the elastic packing 217, the sliding movement of the base 216 is suppressed to some extent by the large frictional force based on the elastic deformation of the packing 217, but the spacer 238 Is not interposed between the counter 202 and the back surface 244 of the counter 202. Therefore, the spacer 238 slides upward along the back surface 244 as indicated by the arrow due to the component force of the tightening force. The problem of moving will arise.
[0013]
Thus, if the spacer 238 causes such a sliding movement, a clamping force is generated on the slide tube 226, so that the slide tube 226 cannot slide up and down smoothly inside the cylindrical member 220. Inconvenience occurs.
That is, there arises a problem that the water discharger 200 cannot be smoothly moved up and down.
[0014]
Although the water discharge part of the shower faucet equipment has been described above as an example, the same problem can occur in mounting the water faucet body, and in common when mounting the water faucet pipe and water faucet body of a normal water faucet. It is a problem.
[0015]
[Means for Solving the Problems]
The water faucet mounting structure of the present invention has been devised to solve such problems.
Thus were those of claim 1, thereby translocating wear faucet device constituting the faucet equipment against inclined mounting surface of the counter or the like mounting base, water stopper device in the mounting hole of the mounting base in that state the a mounting structure of a faucet device for fixing with Rishime Me by the threaded fastener, formed integrally with the spacer portion having a horizontal clamp object surface to the rear surface of the mounting base, surface with該被fastening Further, the present invention is characterized in that the tightening force of the screw fastener is exerted on.
[0016]
According to a second aspect of the present invention, in the first aspect, the faucet device is a water discharger.
[0017]
According to a third aspect of the present invention, in the second aspect, the water discharge section includes a water discharge head that can be moved up and down together with a hose, and a holder that holds the water discharge head, and the inside of the cylindrical member fixed to the mounting base. And a slide tube inserted so as to be slidable up and down together with the water discharge head.
[0018]
