JP-A-8-49268

  In the case of a mechanism for screwing a bolt or the like from the outer periphery of the decorative cover toward the shaft center, it is necessary to provide a bolt hole for inserting the bolt in the radial direction of the decorative cover. Therefore, the thickness of the decorative cover is at least the outer diameter of the bolt. It must be larger. For this reason, it is difficult to reduce the thickness of the decorative cover, and it is impossible to meet various design requirements. Further, even if the design is based on the premise that the decorative cover is provided with a bolt hole, or the design is such that the cover is provided on the bolt hole, a decrease in design is inevitable.

  On the other hand, in the faucet device described in Patent Document 1 (“faucet handle mounting structure”), the position where the fastening of the decorative cover is completed is the fixing position of the decorative cover, so the decorative cover is fixed in the rotation direction. The position cannot be determined freely. For this reason, if the decorative cover has a polygonal shape or an index is provided, each decorative cover cannot be fixed in an appropriate posture.

  The problem to be solved by the present invention is that it can be easily disassembled and assembled without using a tool, the decorative cover can be fixed at an arbitrary position in the rotation direction, and the decorative cover can be made thin. It is possible to provide a faucet device that can be improved in design.

The faucet device of the present invention is a faucet device provided with a flow rate adjusting valve that is installed on a predetermined installation surface and controls the amount of water discharged by the amount of rotation of an operation lever,
A valve case inserted and fixed in a mounting hole opened on the installation surface; a flow rate adjusting valve disposed in the valve case; an operation lever serrated to the flow rate adjusting valve via a connecting shaft; A holding member screwed to the valve case in a state where the connecting shaft portion of the operation lever is rotatably supported, and an axis direction of the holding member that is rotatable to the holding member to cover the upper end portion of the valve case And a makeup cover supported movably,
In the region where the decorative cover moves in the axial direction of the holding member,
An interlocking position in which the decorative cover and the holding member are engaged to transmit the rotation of the decorative cover to the holding member;
A movable position in which the decorative cover is rotatable away from the holding member and the valve case;
And a fixed position where the decorative cover is engaged with the valve case and the rotation of the decorative cover is restricted.

  With this configuration, by moving the decorative cover in the axial direction of the holding member, the decorative cover can be disposed at any one of the interlocking position, the movable position, and the fixed position. It is possible to rotate together, rotate only the decorative cover, or fix the decorative cover at an arbitrary position in the rotation direction.

  That is, when the decorative cover is moved in the axial direction of the holding member and disposed in the interlocking position, the decorative cover and the holding member are engaged and the holding member is rotated together with the decorative cover, so that the decorative cover is rotated. Thus, the holding member can be screwed into the valve case or loosened. Further, when the decorative cover is arranged at the movable position, the decorative cover can be rotated around the axis of the holding member without being restricted by other members, so the decorative cover is set in an arbitrary posture in the rotation direction. be able to. Furthermore, when the decorative cover is disposed at a fixed position, the decorative cover is fixed to the valve case so as not to rotate. Therefore, a bolt is screwed into the axial center of the holding member, or a screw is interposed between the decorative cover and the valve case. There is no need to provide a mechanism. Therefore, the faucet device of the present invention can be easily disassembled and assembled without using a tool, can fix the decorative cover at an arbitrary position in the rotational direction, and can also make the decorative cover thinner. And design properties can also be improved. Note that the operation lever and the connecting shaft portion constituting the faucet device of the present invention may be either an integral structure or a separate structure.

  In this case, it is preferable that the interlocking position, the movable position, and the fixed position are arranged in this order from the upper side to the lower side in the axial direction of the holding member. With such a configuration, these regions are arranged in accordance with the work sequence when assembling the faucet device, so that workability during assembly and disassembly is improved. Further, since the movable position is located between the interlocking position and the fixed position, each area can be clearly recognized even if the moving area of the decorative cover is narrowed, so that the compactness can be achieved. It is also possible to arrange the fixed position, the interlocking position, and the movable position in this order from the upper side to the lower side in the axial direction.

  Moreover, if the holding member is provided so that the position of the decorative cover is restricted at each of the interlocking position, the movable position, and the fixed position, the decorative cover is restricted at each of these positions. Therefore, the operability for the decorative cover is improved.

  On the other hand, it is desirable to pivotally support the decorative cover between the holding member and the connecting shaft portion of the operation lever. With such a configuration, the decorative cover can be pivotally supported in a stable state at all times, so that the decorative cover can be easily rotated and the holding member can be moved in the axial direction.

  Further, when the decorative cover is engaged with the holding member on the inner side and is engaged with the valve case on the outer side, the decorative cover is compared with the holding member when the decorative cover is engaged with the holding member and rotated together. Since a large rotational force can be applied, it can be firmly screwed to the valve case.

  Furthermore, if an auxiliary member that presses and fixes the holding member to the connecting shaft portion is provided, it is possible to prevent the play from occurring between the connecting shaft portion and the holding member.

  According to the present invention, it is easy to disassemble and assemble without using a tool, the decorative cover can be fixed at an arbitrary position in the rotation direction, the decorative cover can be thinned, and the design is improved. It is possible to provide a faucet device.
