Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fixing a hot and cold water mixing tap for fixing a hot and cold water mixing tap provided on a faucet mounting plate portion (hereinafter referred to as a face plate) of a kitchen sink, a wash basin, a bathtub or the like with a bolt. It is related to the mechanism.

[0002]

As a so-called stand-in type hot and cold water mixing tap provided on the face plate, a mixing tap body provided with a mixed hot and cold water discharge pipe has a mixing ratio of hot and cold water and a water discharge amount including still water. Although there is a lever provided with an adjustment function, in such a hot and cold water mixing tap, in addition to the water supply pipe connected to the hot and cold water mixing tap body and the hot water feeding pipe, it is hung downward from the hot and cold water mixing tap body. There is no fixing mechanism for the hot and cold water mixing tap, which is capable of securely installing the hot and cold water mixing tap main body to the upper surface of the face plate of the sink, for example, by fastening operation with the nut by using the bolt.

The present invention has been made in view of the above problems, and an object thereof is to facilitate a main body of a hot and cold water mixer on the upper surface of the face plate of a sink, for example, by using a bolt that is hung downward from the main body of the hot water mixer. It is an object of the present invention to provide a fixing mechanism for a hot and cold water mixing tap using a bolt that can be reliably installed by various operations.

[0004]

In order to achieve the above object, the present invention is directed to a bolt vertically extending from a main body of a hot and cold water mixer, and a faucet mounting plate portion for a sink, a wash bowl, a bathtub or the like of a kitchen. A through hole, a nut for screwing onto the outer peripheral surface of the bolt inserted in the through hole to fix the hot and cold water mixing tap body to the upper surface of the water tap mounting plate, and a part of the peripheral edge. It has a notched, substantially horseshoe shape, and has a through hole of a size that allows the bolt to be inserted and loosely fitted in a recess formed at an inward position apart from the notched portion, while a hot and cold water mixing plug is provided at a position near the notched portion. The water supply pipe and the hot water supply pipe are connected to the main body, and the bolt is inserted into the through hole and the insertion hole, and the hot and cold water mixing plug body is attached to the faucet mounting plate by fastening operation of the nut and the bolt. Install the faucet so that it is fixed to the upper surface of the part And a taper portion having an edge capable of being fitted in the valley of the bolt in a plan view substantially crescent-shaped and a mountain of the bolt at the periphery of the insertion hole of the mounting metal. A claw capable of abutting is formed, and a protrusion for preventing rotation is formed on a surface of the mounting bracket that abuts a lower surface of the faucet mounting plate portion.

That is, according to the present invention, a bolt is hung downward from a water supply pipe and a main body of a hot and cold water mixing plug connected to the hot water supply pipe, and a fastening operation of the bolt and the nut presses the lower surface of the faucet mounting plate portion. Since a horseshoe-shaped mounting bracket is provided,
When the fastening operation is completed, the anti-rotation projection formed on the mounting bracket abuts the lower surface of the faucet mounting plate portion, so that the mounting bracket can be prevented from rotating.

Further, an insertion hole having a size that allows the bolt to be inserted and loosely fitted is formed in the recess of the mounting member, and a peripheral portion of the insertion hole is provided with a substantially crescent-shaped tapered portion in plan view and a claw. Therefore, in the middle of the fastening operation, after inserting the bolt into the insertion hole of the mounting bracket and before screwing the nut onto the outer peripheral surface of the bolt, simply tilt the mounting bracket to remove the tapered portion from the bolt. In a state where it is fitted in the valley of and the claw is in contact with the crest of the bolt (the state where it is hooked),
The mounting bracket can be temporarily fixed. As a result, the mounting bracket can be prevented from falling from the bolt, and the installer can perform the nut tightening operation with one hand without having to worry about the mounting bracket falling.

Then, at the final stage of the fastening operation in which the water supply pipe and the hot water supply pipe are inserted through the insertion portion of the mounting bracket and the nut is tightened, the nut contacts the recess formed in the mounting bracket by the tightening operation. Upon contact, the mounting metal fittings, which have been temporarily fixed until then, move from the inclined state to the horizontal state, and the fitting of the tapered portion and the hooking of the claw on the outer peripheral surface of the bolt are released. Therefore, the bolt is loosely fitted in the insertion hole of the mounting bracket, and then the taper portion and the claw move on the outer peripheral surface of the bolt by the further tightening operation, and finally the protrusion for preventing rotation is locked. It can be brought into contact with the lower surface of the plug mounting plate portion.

For example, if at least one end surface of the nut is formed with an annular protrusion that abuts against the tapered portion, the protrusion for preventing rotation can not only prevent the attachment fitting from rotating but also prevent rotation. Since the annular projection can be brought into contact with the tapered portion formed in the recess of the mounting fitting in a state where the projection of the fitting is brought into contact with the lower surface of the faucet mounting plate portion, the rattling in the front-rear direction of the mounting fitting is prevented. Can be stopped,
The fixing of the body of the hot and cold water mixing tap to the upper surface of the water tap mounting plate can be made stronger.

When it abuts against the recess 11 that has been made, as shown in FIG. 8, the fitting 10 that has been temporarily fixed until then moves from the inclined state to the horizontal state, and the edge E of the taper portion 14 on the outer peripheral surface P of the bolt 4 is moved. And the hooking of the claw 15 are released. Therefore, the bolt 4 is loosely fitted in the insertion hole 12 of the mounting member 10, and then the tapered portion 14 and the claw 15 move on the outer peripheral surface P of the bolt 4 by a further tightening operation,
Finally, the rotation preventing protrusion 16 can be brought into contact with the lower surface N of the face plate 5.

Moreover, since the annular projections 17 are formed on both end surfaces 9a, 9b of the nut 9 so as to abut the tapered portion 14, the projections 16 not only prevent the mounting bracket 10 from rotating, but also prevent rotation. Since the annular projection 17 can be brought into contact with the taper portion 14 formed at the lowermost portion of the recess 11 of the mounting member 10 with the projection 16 for use in contact with the lower surface N of the face plate 5, the mounting member can be mounted. It is possible to prevent backlash in the front-back direction of 10, and the upper surface L of the face plate 5 of the hot and cold water mixing stopper body 1.
