BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism for a hydrant handle, and more particularly to a lock mechanism for a hydrant handle that can be fixed at a predetermined operation position.

[0002]

2. Description of the Related Art Some water taps are provided with various operation handles, such as a switching handle for switching between shower and water discharge of a callan, and a temperature control handle for adjusting the temperature of water discharge.

[0003]

When a water tap provided with such an operation handle is used, it is not necessarily required that the operator is familiar with the operation method and functions of the operation handle. You may accidentally use the hydrant. For example, a child or an elderly person may accidentally use the switching handle and take hot water in a shower, even though the intention is to spout water from the callan. Therefore, in normal use, in addition to being able to operate the operation handle normally, a lock mechanism for the hydrant handle that prevents operation of the handle in a predetermined case is required.

[0004] In some cases, it is desired to hold the handle at a predetermined position without erroneous operation. For example, when it is necessary to continuously discharge a certain amount of hot water to prevent freezing in a cold region or to prevent the toilet from becoming dirty, the handle is prevented from being operated to a position other than the predetermined water discharging position. There is a need to. Further, when the water supply is not used for a certain period, it is necessary to keep the hydrant closed so as not to be used. In such cases, in particular,
There has been a need for a lock mechanism for the hydrant handle that prevents any operation of the handle except in a predetermined case. A problem to be solved by the present invention is to prevent an erroneous operation of a handle by fixing an operation position of a handle for operating a water tap as required. Another object is to prevent the steering wheel from being operated when it is not desired to operate the steering wheel.

[0005]

The above-mentioned invention is characterized in that a lock mechanism for fixing the handle to a predetermined operation position is provided on a hydrant handle for performing operations such as water discharge of a hydrant. Is what you do. A lock mechanism capable of completely fixing an operation handle at a predetermined operation position is provided. With this configuration, it is possible to prevent erroneous operation of the steering wheel operation and to prevent the steering wheel from being operated when it is not desired to operate the steering wheel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the hot and cold water mixing faucet 1 switches between shower sprinkling from a shower head (not shown) connected to the tip of the shower hose 3 and water spouting from a spout 4, and also performs spitting. Switching handle 10 and temperature adjusting handle 2 for adjusting the temperature of spouting water
0 are provided on the main body 2 of the hot and cold water mixing faucet 1 so that each operation can be performed by rotating the handle around the handle axis. Each of the handles 10 and 20 is provided with a lock mechanism 30 that disables and fixes a rotation operation of the handle. At the center of the front of the main body 2, a switching handle mounting portion 5 is provided. A switching handle 10 is fixed to a shaft 6 protruding from the center of the mounting portion 5 with screws (not shown). Further, the engagement portion 12 inside the switching handle 10 is fitted into the serration 7 around the shaft 6, and the shaft 6 and the switching handle 10 are fixed. By rotating the switching handle 10, the shaft 6 is rotated. A switching valve (not shown) is operated through the switch to switch between water discharge and water discharge / shower water spray.

Next, the details of the lock mechanism 30 will be described with reference to FIGS. 1 and 2, taking the lock mechanism 30 provided on the switching handle 10 as an example. The lock mechanism 30 includes a slide button 40, a slide button slide hole 11 provided in the switching handle 10, and a fixing notch 8 provided in the mounting portion 5 of the switching handle 10.
It is composed of

The slide button 40 includes an operation portion 41, an insertion portion 42 that is formed to rise from substantially the center of the back side of the operation portion 11 and is inserted through the slide hole 11, and an end of the insertion portion 42. In the longitudinal direction, the operation unit 4
1 comprises a fitting portion 43 protruding substantially in parallel with the fitting portion 43.
The operation unit 41 is provided in a substantially rectangular thin plate shape as a whole, and on the front side thereof, a large number of grooves 44 formed in a continuous manner in the short direction and formed in a wavy shape are slid in the longitudinal direction thereof. In this case, the finger is provided so that the finger does not slip easily from the slide button 40. The fitting portion 43 is provided in a substantially rectangular thin plate shape, and is provided continuously from an end of the insertion portion 42 almost in parallel with the operation portion 41.

The notch 8 is provided in the mounting portion 5 of the main body 2. The mounting portion 5 is formed so as to stand substantially cylindrically from the main body 2 toward the front side, and has an outer diameter slightly smaller than an inner diameter of the switching handle 10 formed in a bottomed cylindrical shape. Accordingly, the mounting portion 5 is provided so as to be insertable inside the switching handle 10. A notch 8 for fixing the switching handle 10 is provided at an end 9 on the front side of the mounting portion 5 and is cut out in a substantially rectangular shape.

Next, the operation of the switching handle 10 will be described. Normally, as shown in FIG. 2A, the slide button 40 of the lock mechanism 30 is located in the direction of the tip of the switching handle 10, whereby the fitting portion 43 is not engaged with the notch 8. . Therefore, the switching handle 10 can be rotated around its axis as shown in the figure, and the switching valve can be operated.

On the other hand, when the slide button 40 is slid toward the main body 2 as shown in FIG.
Is engaged with the notch 8 to disable the turning operation of the switching handle 10. In the present embodiment, the notch 8 is provided at a position where the switching handle 10 can stop water discharge.

Since the present embodiment is configured as described above, if the slide button 40 is positioned on the main body 2 side, the operation of the steering wheel becomes impossible, and the water discharge from the water discharge port 4 or the shower head is stopped. Switching handle 1
0 can be fixed. Therefore, there is no possibility of inadvertently discharging water from the water discharge port 4 or the shower head.

In the lock mechanism 30 described above, if an urging means for urging the slide button 40 in the notch 8 direction is provided, if necessary, the slide button 40 is slid against the urging force of the urging means. The handle can be operated. On the other hand, the handle 10, 20 can always be fixed by engaging the fitting portion 43 with the notch 8 by the urging force in the normal state. With such a configuration, it is possible to always prevent the handles 10 and 20 from being operated unless there is a clear intention to release the lock mechanism 30.

The lock mechanism 30 constructed as described above
Is not limited to being used for the switching handle 10. As shown in FIG. 1, a lock mechanism 30 can also be provided on the temperature adjusting handle 20 provided on the hot and cold water mixing faucet 2. Like the switching handle 10, the temperature adjustment handle 20 is operated by being rotated around an axis of a main body provided in a cylindrical shape. By providing the lock mechanism 30 on such a handle, water discharge at a desired temperature can always be obtained.

In the above-described embodiment, the lock mechanism 30 using the slide button 40 is employed. However, the present invention is not limited to this, and it is sufficient if the operation of the steering wheel is disabled. When the member is protruded into the handle by pushing the button, the handle is fixed by locking the notch 8 provided on the main body 2 side, and when the button is pressed again, the member is retracted and the fixed state of the handle is set. It may be such that it is released. In the present embodiment, the switching handle 10 for performing a rotating operation is provided.
Although the lock mechanism is provided on a handle such as the temperature control handle 20 or the like, the present invention is not limited to this, and can be widely used for a handle used by operations other than rotation, such as a lever handle.

If these lock mechanisms are provided with a key or the like, the operation of the handle can be prevented by locking the lock mechanism. For example, a water tap installed outdoors can be tampered with or stolen. Can be prevented.

[0017]

According to the present invention, the handle for operating the water tap is provided with a lock mechanism for disabling the handle operation as described above, so that erroneous operation of the handle and operation of the handle can be performed as necessary. It is possible to prevent the steering wheel from being operated when it is not desired.
