Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lever handle for externally operating a valve element that opens and closes a flow path of a faucet body.

[Conventional technology]

BACKGROUND ART Conventionally, there is a valve element disposed inside a faucet body which is opened and closed using a lever handle, as described in Japanese Utility Model Publication No. 56-26134.

This is a single-lever handle type hot water mixing faucet, and the mixing amount and discharge flow rate of hot water can be adjusted by rotating the lever handle and tilting it in the front and rear directions.The lever handle is located halfway at the rear of the faucet body. The valve is pivotally mounted, and its tip engages the valve element to perform opening and closing operations.

Additionally, an opening is provided at the top of the faucet body for incorporating a valve element and other equipment into the faucet body;
A display cap with hot water and water markings on its surface is arranged to close this opening, and is fixed with a cap nut screwed onto the upper part of the faucet body.

[Problem that the invention attempts to solve]

However, as described above, in the conventional structure, the cap nut can be easily removed from the outside, so when the cap is installed for public use, there is a risk that the cap may be ripped off by tampering or the like.

When the cap nut and cap are removed from the faucet body, the internal valve mechanism is exposed, and foreign objects can get in and make the movable parts inoperable.Also, there is no indication when using the faucet, so it is difficult to adjust the lever handle properly. There is a problem in that it becomes unclear which operation to perform, and the user must immediately refill the cap or replace the entire faucet.

The purpose of the present invention is to provide a faucet device configured to engage a valve element inside the faucet body and open/close the valve element from the outside using a handle, in which an indicator cap indicating the operating direction of the handle, etc. cannot be removed from the outside;
The purpose is to maintain the operation and operation of faucets.

[Means to solve the problem]

The present invention includes a lever handle, a mounting base that fixes the base end of the lever handle and is connected to a valve element of a faucet body, and an indicator cap that is integrally fixed to the mounting base together with the lever handle, An annular portion is provided at the base end of the lever handle, and a protrusion having a linear planar shape is formed on a part of the inner periphery of the annular portion, and the mount is aligned with the protrusion 15 of the annular portion. A stepped portion is provided on the outer peripheral surface to receive this, and the upper and lower surfaces of the annular portion are overlapped and restrained by the display cap and the mounting base, respectively, and a fixing screw is screwed into the display cap from the back side of the mounting base. It is characterized by what it did.

With this configuration, the screws are contained within the mount and cannot be seen from the outside, so the display cap will not be peeled off unless the mount is removed from the faucet body. In addition, since the position of the lever handle in the turning direction is restricted by the protrusion formed on its inner circumference and the stepped part of the mounting base, the lever handle can be held in the correct position relative to the mounting base without having to pass a screw through the lever handle. Fixed.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a partially cutaway side view showing the application of the present invention to a single-lever type hot and cold water mixing faucet.

A valve element 3 is arranged inside the faucet body 1 and can be operated by operating a lever handle 2 to arbitrarily change the mixing ratio of hot water and water.A water discharge pipe 5 is provided at the lower end of the mixing chamber 4 through which the mixed water flows. They are connected so that they can rotate freely.

The upper end of the faucet main body 1 is open, and 6 is a cap-shaped mounting base that covers this opening from above and fixes the lever handle 2, and an operating arm 7 that engages with the valve element 3 on the lower surface thereof. It is stuck in place.

Reference numeral 8 denotes a display cap which is connected to the upper part of the mounting base 6 by screws 9, and has a display necessary for operating the lever handle 2 on its surface, and fixes the lever handle 2 between it and the mounting base 6.

2 is a top plan view of the mount 6, and FIG. 3 is a cross-sectional view taken along the - arrow in FIG. A concave portion A is formed. Further, the upper surface side is cut out so that two opposing sides are linear to form a stepped portion 10, and a linear vertical wall 11 of this stepped portion 10 functions as a rotation stopper for the lever handle 2. Further, reference numeral 12 indicates a screw hole through which the screw 9 is inserted from below in the concave portion A, and in this example, it is opened at three positions.

FIG. 4 is a plan view of the lever handle 2, which is made of a material different from that of the metal faucet body 1, and in this embodiment is made of polycarbonate.

The lever handle 2 has a handle part 13 for operation, and an annular part 14 that fits into the stepped part 10 of the mounting base 6. On the inner periphery of the annular part 14, linear protrusions 15 are provided on two opposing sides. has been established. This protrusion 15 fits into the stepped portion 10 of the mounting base 6 in an aligned state, and functions as a mechanism to prevent slippage when the lever handle 2 is rotated.

FIG. 5 is a cross-sectional view of the display cap 8, which is formed by extending downwardly a cylindrical portion 17 having a screw hole 16 into which the screw 9 is screwed. A stepped portion 18 that fits into the periphery is provided. Further, reference numeral 19 denotes a display recess formed on the surface, and the display body 8a is formed by filling colored epoxy resin into the recess 19 and hardening it.

The device for attaching the mount 6 that integrates the lever handle 2 and the display cap 8 to the faucet main body 1 is a fitting tube 20 for the arm 7 formed on the lower surface of the mount 6.
This is done by screwing in the fixing screw 21 from the outside.

That is, a notch 22 is provided on the back of the mounting base 6, the lever handle 2 is rotated as much as possible clockwise in FIG. 2. The structure allows the installation base 6 and display cap 8 to be attached to the faucet body 1 as a single unit.

In the above structure, the lever handle 2 has the mounting base 6 and the display cap 8 fitted into the annular part 14 from both upper and lower sides as shown in FIG. be done.

In this case, since the screw 9 is screwed into the concave portion A of the mounting base 6 from the lower surface side, the screw 9 is not exposed to the outside when it is attached to the faucet main body 1.

Therefore, once the lever handle 2 is attached to the faucet body 1 together with the mounting base 6 and the display cap 8, the display cap 8 and the lever handle 2 cannot be disassembled from the outside, thereby preventing theft.

[Effect of idea]

With this invention, the screws cannot be removed unless the mounting base is removed from the faucet body, so there is no possibility that the display cap or lever handle will be stolen, and it can be optimally used for public equipment.
In addition, the lever handle has its annular portion at its proximal end restrained and fixed by the mounting base and display cap, and its position is regulated by the protrusion and step.
Can be installed correctly on the mounting base. Furthermore,
Since the annular portion fits around the entire circumference of the mount, the operating force and reaction force of the lever handle are not concentrated at one point on the mount or the lever handle, reducing fatigue of the members and improving durability.
