Description

  The present invention relates to an operating lever mounting structure, and more particularly to an operating lever mounting structure that attaches to a faucet with a good looking operating lever for adjusting the water discharge flow rate by tilting.

  In recent years, as shown in Patent Document 1 below, a single-lever hot and cold water mixing tap with improved design has been used that enables adjustment of the flow rate and temperature of water discharged by tilting an operation lever provided at the top of the faucet body. Yes.

  FIG. 19 is a view for explaining the configuration of this type of conventional hot and cold water mixing plug 90. The operation lever 91 shown in FIG. 19 is provided with a flange 92 having a substantially spherical surface at the base thereof, and so-called a dome-shaped flange structure. By providing the flange 92, the flange 92 can be moved as the operation lever 91 is tilted to cover the faucet opening 93, and foreign matter can be prevented from entering the faucet.

Special table 2007-518033 gazette

  However, in the configuration shown in FIG. 19, since the flange 92 has a substantially spherical surface, a dome-shaped protrusion is formed at the base of the operation lever 91, which increases the height Hp of the hot and cold water mixing tap. Become. In addition, it looked bad and the faucet could not be freely designed.

  Further, in the conventional dome-shaped flange structure cover, the flange 92 provided on the operation lever 91 moves as the operation lever 91 is tilted, so that one end 92a of the cover corresponds to a member on the faucet body side such as the faucet cartridge 94. Therefore, it is necessary to limit the movable range of the operation lever 91.

  On the other hand, as shown in FIG. 20, when the width of the flange 92 is narrowed to widen the movable range of the operation lever 91 and the opening 93 is enlarged, the other end 92b of the flange 92 protrudes from the opening 93, and the hot and cold mixing plug 90 There is a problem that foreign matter is mixed in.

  In addition, since it is necessary to form a gap d between the flange 92 and the opening 93, water on the hand during use of the faucet passes through the surface of the flange 92 and passes through the gap between the opening 93 and the flange 92. The water faucet is unsanitary, and there is a concern that the water faucet malfunctions due to water or foreign matter accumulated inside the faucet.

  The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide an operation lever mounting structure capable of ensuring a sufficient movable range of the operation lever and making the faucet body compact. The issue is to provide.

In order to solve the above problems, the present invention provides:
Operation in a faucet having an operation lever for projecting outward from the faucet body through an opening provided on the outer surface of the faucet body and adjusting at least the water discharge flow rate of the water discharge pipe provided in the faucet body by tilting The lever mounting structure,
From the opening to the inside of the faucet body,
A decorative cover having a lever operation window that covers the opening and through which the operation lever is inserted;
A sliding surface forming member;
A substantially flat plate shape that has a lever through hole that is penetrated by the operation lever and is smaller than the lever operation window, and that slides along the sliding surface forming member while always covering the lever operation window as the operation lever is tilted. A sliding cover of
A pressing member that presses the sliding cover against the sliding surface forming member is provided in this order (Claim 1).

  According to the operation lever mounting structure having the above-described configuration, the decorative cover covers the opening, and the design can be applied to the faucet. In addition, the static friction resistance generated between the sliding surface forming member that contacts the back surface of the decorative cover and the sliding cover is kept low, and the sliding of the sliding cover with respect to the sliding surface forming member is good (sliding property). As a result, the operation lever can be tilted with a little force.

  The sliding cover slides along the sliding surface forming member in accordance with the tilting operation of the operating lever, and the lever operating window is covered with the sliding cover regardless of the position of the operating lever. In addition, since the sliding cover is not a dome shape but a substantially flat plate shape, the faucet body can be made compact accordingly, and the sliding cover does not hit the faucet cartridge etc. like the dome-shaped flange structure, The operating angle of the operating lever can be increased by enlarging the lever operating window. Furthermore, the movement (sliding) of the sliding cover accompanying the tilting of the operating lever is difficult to visually recognize from the outside through the lever operating window because the sliding cover is substantially flat, and thus the water during operation of the operating lever can be reduced. The appearance of the stopper is refined.

  Since the pressing member presses the sliding cover against the sliding surface forming member, the sliding cover and the sliding surface forming member are in close contact with each other, and dust and foreign matter are prevented from entering between them. Can be prevented from entering.

  The faucet may be a hot and cold water mixing tap, that is, a single lever type hot and cold water mixing tap. In this case, the water discharge flow rate and temperature of water discharged from the water discharge pipe can be adjusted by tilting the operation lever. What is necessary is just to set the inclination direction of an operation lever, and the shape of the said lever operation window can be made into substantially circular shape, for example. However, the faucet may be a single faucet, and in this case, the shape of the lever operation window may be a slit shape.

  The decorative cover may be a lid formed so as to be fitted into the opening of the faucet body. In this case, the decorative cover is made of metal or metal plating so as to match the material and design of the faucet body. It is preferable to form with a hard synthetic resin or earthenware so as to obtain a sense of unity with the faucet body. However, even if the decorative cover is a cover that covers the entire surface of the faucet, or a thin layer that is formed to cover the opening of the faucet body by metal plating or application, the faucet is designed. If it is.

  The decorative cover has a plate-like portion in which a lever operation window is formed, and a cylindrical portion provided continuously to the plate-like portion, and a groove ( In order to improve the appearance, it is preferable to provide the sliding surface forming member by avoiding the lever operating window so that the sliding surface forming member does not appear in the lever operating window. Moreover, you may stick a sliding surface formation member on the back surface side of a decorative cover using an adhesive agent etc.

  Like the decorative cover, the sliding cover has a substantially flat plate shape made of a hard synthetic resin, for example, metal or metal plated according to the material and design of the faucet body. This is preferable. The lever through hole is preferably a hole having a minimum size through which the base of the operation lever passes.

  The pressing member is preferably made of an elastic material. In this case, the sliding cover can be pressed against the sliding surface forming member using the elastic force of the pressing member, but a spring or the like can be used. The pressing member may be pressed against the sliding cover using the biasing means. Note that another sliding surface forming member may be interposed between the sliding cover and the pressing member.

  In the case where the sliding surface forming member is a sheet-like member made of polyacetal (Claim 2), the static friction resistance can be suppressed sufficiently low, so that the contact surface between the sliding surface forming member and the sliding cover is further increased. Adhering with a strong force can more reliably prevent dust and foreign matter from entering the faucet body.

Further, the operation lever mounting structure of the present invention projects outward from the faucet body through an opening provided on the outer surface of the faucet body, and at least reduces the water discharge flow rate of the water discharge pipe provided in the faucet body by tilting. An operation lever mounting structure in a faucet having an operation lever for adjusting,
From the opening to the inside of the faucet body,
A decorative cover having a lever operation window that covers the opening and through which the operation lever is inserted;
A substantially flat slide that has a lever through-hole that is penetrated by the operation lever and is smaller than the lever operation window and that slides along the decorative cover while always covering the lever operation window when the operation lever is tilted. A moving cover,
A pressing member that presses the sliding cover against the decorative cover may be provided in this order (Claim 3). In this case, since the sliding surface forming member is not separately provided, the configuration becomes simpler.

  The pressing member has a substantially C-ring shape having a notch that allows the outer periphery of the pressing member to be elastically deformed in the direction of diameter reduction, and has a tapered surface on the outer periphery. A guide portion having a taper receiving surface that comes into contact with the taper surface in a state in which the member is reduced in diameter is provided, and the pressing member has the taper receiving surface with respect to the taper surface as the diameter is increased from the reduced diameter state. If the guide is configured to slide toward the sliding cover side (Claim 4), the tapered surface of the substantially C-ring-shaped pressing member is tapered with the diameter slightly reduced. Since the pressing member is inserted into the guide portion so as to contact the surface and the guide of the taper receiving surface with respect to the tapered surface tries to move toward the sliding cover side, the sliding cover is brought into close contact with the sliding surface forming member. Yo It can continue to be biased in. Further, the pressing member can be detachably attached to the guide portion having the taper receiving surface by reducing the diameter, and the assembling property and the maintenance property are excellent.

  Holes for inserting a tool for elastically deforming the pressing member in the diameter reducing direction are preferably formed at both ends of the notch portion of the substantially C-ring-shaped pressing member. It is preferable that the elastic deformation part is formed with a narrow width. The material of the pressing member is preferably a synthetic resin having elasticity as a spring material.

  In the case where the pressing member has a male screw on the outer peripheral portion and a guide portion having a female screw into which the male screw is screwed is provided on the inner side of the opening (Claim 5), the guide portion is pushed against the female screw. The force for pressing the sliding cover against the sliding surface forming member can be adjusted by adjusting the screwing amount of the male screw of the contact member.

  A case in which a cylindrical member attached to the base of the operation lever so as to be movable in the axial direction thereof and an urging means for urging the cylindrical member in a direction in contact with the sliding cover are provided (Claim 6). Since the cylindrical member abuts on the sliding cover, the gap between the sliding cover and the operation lever can be covered, and the appearance is good. In addition, it is possible to more effectively prevent dust and foreign matter from entering the faucet.

  In particular, the lower end portion of the cylindrical member preferably has a spherical curved surface, and the peripheral wall of the lever through hole provided in the sliding cover preferably has a curved surface that comes into contact with the spherical curved surface of the operation lever. . In addition, it is preferable to arrange | position synthetic resin for keeping watertight as packing at the contact part of a cylindrical member and a lever through-hole.

  As described above, according to the present invention, it is possible to provide a mounting structure for an operation lever that can reduce the size of the faucet and prevent dust and foreign matter from entering the faucet and can provide a free design.

  In addition, when a tapered surface is provided on the outer peripheral portion of the pressing member and a guide portion having a tapered receiving surface is provided inside the opening, the watertight state between the sliding surface forming member and the sliding cover is reliably maintained. It is possible to improve the assembling property and the maintenance property.

  When a cylindrical member is provided at the base of the control lever, the gap between the sliding cover and the control lever connection can be filled, and the appearance will be better, and dust and foreign matter will enter the faucet more reliably. Can be prevented.
