Description

  The present invention relates to a structure for assembling a decorative cap to a screw fixing member for fixing a valve unit to a faucet body.

  Conventionally, a structure that fixes a valve unit containing a fixed valve body and a movable valve body to a faucet body by screwing a fixing nut (fixing member) into the faucet body side in a single lever faucet has been widely adopted. ing.

In this single lever faucet, the water discharge temperature is adjusted by rotating the lever handle in the left-right direction as viewed from the user.
In this case, it is necessary to clearly indicate to the user which temperature adjustment position the current handle position is, that is, at what temperature water discharge is performed.
Conventionally, the display for that is often given to the outer surface on the faucet body side, that is, the decorative surface.

  By the way, the single lever faucet can rotate a cylindrical portion that forms a part of the faucet body housing so that the water discharge pipe extends from the cylindrical portion, so that the water discharge pipe is within a predetermined angle range. Although there is something that can be rotated, if the above display is given on the outer surface of this cylindrical part, that is, the upper part of the decorative surface near the lever handle, the display itself rotates and moves due to the rotation of the water discharge pipe. It will change and cannot function as the original display.

  In such a case, a cosmetic cap that covers the exposed portion of the fixing nut to the outside from the outside and hides it inside is arranged at the upper position following the cylindrical portion, and is attached to the fixing nut. It is convenient to provide the above indication on the outer surface of the cap.

However, when the decorative cap is assembled to the fixing nut so as not to rotate, the fixing nut is rotated when fixing the valve unit to the faucet body, and is screwed to the faucet body side as much as possible, that is, the final screwing position is Since the position is not constant, the position of the display rotation direction cannot be determined.
Therefore, even if the decorative cap is assembled to the fixed nut, it is necessary to make it rotatable with respect to the fixed nut.
An example for this is disclosed in Patent Document 1 below.

In the one disclosed in Patent Document 1, a male spline portion is provided over the entire circumference on the side of the fixing nut, and a female spline portion is provided over the entire circumference on the side of the decorative cap, and their meshing positions are changed. Thus, the rotational direction position of the decorative cap relative to the fixing nut can be adjusted.
However, the one disclosed in Patent Document 1 has a problem that the rotational direction position of the decorative cap relative to the fixing nut cannot be finely adjusted.
In the one disclosed in Patent Document 1, the position of the makeup cap is limited to a position where the male spline portion and the female spline portion can mesh with each other, and one pitch of each meshing tooth of the male spline portion and the female spline portion. The delicate position adjustment of the cosmetic cap within the following range is not possible.

Depending on the faucet, the display position may have to be strictly determined according to the movable range of the handle. In such a case, in the method disclosed in Patent Document 1, the display position is set to a preset position. It cannot be positioned exactly.
In addition, in the one disclosed in Patent Document 1, the position in the rotational direction cannot be adjusted under the condition that the decorative cap is assembled to the fixed nut. To adjust the position, the decorative cap is once removed from the fixed nut. Above, the position in the rotational direction must be determined, and in that state, it must be re-assembled to the fixing nut, and there is a problem that the work for position adjustment is troublesome.
In addition, providing such spline portions on each of the fixing nut and the decorative cap increases the processing cost.

  As another prior art for the present invention, the following Patent Document 2 discloses a device attached to “a cap mounting structure in a mixed faucet”, in which an annular groove is formed in a faucet body (a faucet body). And attaching a split ring having a cut at a predetermined position in the circumferential direction, and fitting a protrusion on the inner surface of the decorative cap into an annular groove provided over the entire circumference of the split ring, The point which came to assemble is disclosed.

  However, the one disclosed in Patent Document 2 is different in that the face to which the decorative cap is attached via the split ring is not a fixing member such as a fixing nut as in the present invention, but a faucet body. The cap can be freely rotated with respect to the split ring in the assembled state, and the one disclosed in Patent Document 2 is different from the present invention in these respects.
