Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flushing tank for cold regions, and more particularly to a handle device capable of holding its float valve in an open state.

This type of flush tank generally includes a valve seat member with a hot water pipe fixed to the bottom of the tank, and a valve seat member that is pivotally connected to the valve seat member.
a float valve that cooperates with a valve seat of the valve seat member to configure a drain valve;
It consists of a handle device installed on the side wall of the tank and connected to a float valve via a chain. Water supplied through the ball tap is stored in a tank as cleaning water. Washing water for large or small washing can be discharged from the tank by turning the handle device clockwise or counterclockwise to lift the float valve from the valve seat member and open the valve.

Washing tanks used in cold regions are equipped with measures to prevent stored water from freezing. To prevent freezing, the water supply from the pole tap is shut off, the handle is held in the open position, and the float valve is closed. The device is kept raised so that the water stored in the tank is drained to the level of the valve seat member. A device described in Japanese Patent Publication No. 43-26915 is known as a device for holding a handle device in a valve open position. In this device, a recess is provided in the handle spindle supported by a bearing member fixed to the side wall of the tank, and when the handle spindle is rotated to the valve opening position, it engages with the recess in the handle spindle and moves the valve to the valve opening position. A spring loaded ball detent device is provided to keep the ball in place. The detent function of the ball detent device is influenced by adjusting the strength of the spring acting on the ball, and in cold weather the spring is activated so that the detent device always performs its detent function. However, with this configuration, each time the handle is operated, the ball detent device engages with the recess in the handle spindle, so the handle must be returned against the ball detent device, making it difficult to turn the handle. was there.

It is an object of the present invention to overcome the drawbacks of such conventional devices, and to enable the handle to be held in the open position by selectively activating the detent device when drainage is required to prevent freezing. An object of the present invention is to provide a handle device for a flush tank for cold regions.

According to the present invention, the handle device includes a bearing member with a flange fixed to a side wall of a tank, a handle spindle supported by the bearing member, a handle fixed to the spindle, and a flange of the bearing member. a recess provided in the valve opening position of the handle on the surface, and a detent device provided in the handle, the detent device comprising a push-button knock mechanism, a detent element cooperating with the recess, and a detent device. The present invention is characterized in that it has a spring disposed between the element and the knocking mechanism, and configured to increase or decrease the elastic force applied to the detent element in response to a knocking operation of the knocking mechanism. When the knocking mechanism is operated to increase the elastic force of the spring applied to the detent element, the detent element is strongly engaged with the recess in the flange surface to hold the handle in the valve open position. When releasing the knock mechanism, the spring force is reduced and the handle is free to return to its original position.

An example of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, a flush tank 1 has a valve seat member 3 with a hot water pipe fixed to its bottom 2 and connected to a flush pipe (not shown) extending from the toilet bowl, and a float valve 4 is connected to the valve seat member 3. The valve seat 5 is pivotally mounted to the valve seat member 5, and cooperates with the valve seat 6 of the valve seat member to form a drain valve. A flanged bearing member 8 is fixed to the side wall 7 of the tank, and a handle spindle 10 has a handle 9 fixed to one end.
is supported by a bearing member 8 so that it can rotate by a predetermined angle in the clockwise and counterclockwise directions. handle spindle 10
is equipped with a bent arm 11 at its rear end, and the float valve 4 is connected to this bent arm 11 via a chain 12.

Washing water supplied and stored in the tank 1 through a ball tap (not shown) is discharged from the tank for large or small washing by turning the handle 9 and pulling up the float valve 4.

A recess 14 is formed in the flange surface 13 of the bearing member 8 at the valve opening position of the handle 9 (see FIG. 2), and the handle 9 is provided with a detent device 1p. Detent device 1
5 has a push button type knock mechanism 16, and this knock mechanism is
The cylindrical receiver of the handle 9 has a sleeve 18 inserted into the mouth 17 and a protrusion 20 that engages with a plurality of deep spline grooves 19 provided at every other depth on its inner circumference, and A push button 22 that penetrates the hole 21 and protrudes to the outside.
and a spring receiving element 24 on the left side having a protrusion 23 that engages with the deep spline groove 19. The push button 22 has teeth 25 formed on its inner end surface with a peak at the center of the end surface of the protrusion, or the push button 24 has teeth 25 formed on the end surface of its protrusion 23.
An inclined surface 26 is formed which cooperates with the second tooth 25 . The sleeve 18 has a hole 27 having the same diameter as the deep spline groove 19, and a step 28 of the hole 27 has a sawtooth sloped surface 29 formed on its end face extending between adjacent spline grooves.

A detent element 3o that cooperates with the recess 14 provided in the flange surface 13 is slidably provided in the hole 27 of the sleeve 18, and a coil spring 31 is disposed between the detent element 3o and the spring receiving element 24. is located.

As shown in FIGS. 3 and 4, when the knock mechanism 16 is released, the inclined surface 26 of the protrusion 23 of the spring receiving element 24 located within the deep spline s19 pushes the push button 2.
The spring 3 engages with the tooth surface 25' of the tooth 25 of No. 2, and in this state, the spring 3
The impact force of 1 has been reduced. Pushing the push button 22 inward as shown in FIGS. 5 and 6 releases the detent element 30.
is pressed against the flange surface 13 via the spring 31, and the spring receiving element 24 is pushed inward by the push button 22 against the rebound of the spring 31 until the protrusion 23 escapes from the deep spline groove 19. will be moved to When the protrusion 23 disengages from the deep spline groove 19, the spring receiving element 24 is given a rotation so that its sloped surface 26 moves along the tooth flank 25' of the tooth 25 of the push button 22, and the sloped surface 26 18 onto the serrated inclined surface 29 of the stepped portion 28 of the hole 27. Then, since the inclined surface 26 of the protrusion 23 moves along the sawtooth inclined surface 29, rotation is given to the spring receiving element 24 again, and the protrusion 23 hits the abutting surface 32 of the stepped portion 28, forming a deep spline groove. It is held on the inclined surface 29 at a position facing the shallow spline groove 19 adjacent to the spline groove 19 (see FIGS. 7 and 8). The spring 31 is thus compressed between the spring receiving element 24 held in the forward position by the step 28 and the detent element 30;
This makes it possible to increase the elastic force of the spring 31 acting on the detent element 30.

When the knock mechanism 16 is operated prior to the valve opening operation, the detent element 30 is activated without turning the handle 9 to the valve opening position.
After a large elastic force of the spring 31, the handle 9 is engaged with the recess 14 of the flange surface 13 to lock or hold the handle 9 in the open position. Of course, the knock mechanism 16 may be activated after the handle 9 is turned to the valve opening position.

To release the knock mechanism 16, first push the push button 22 inward again. Then, the protruding part 20 of the push button 22 hits the inclined surface 26 of the protruding part 23 of the spring receiving element 24 at the tooth surface 25' of the end face thereof, and the protruding part 23 contacts the abutting surface 32 of the step part 28. Push inward against the action of spring 31 until it releases. When the protrusion 23 comes off the contact surface 32,
The inclined surface 26 moves along one toothed surface 25' of the tooth 25 on the end face of the push button 22 to rotate the spring receiving element 24, so that the inclined surface 26 of the protrusion 23 follows the serrated inclined surface 29 of the step 28.
Get on or move on. Then, the inclined surface 26 of the protruding portion 23 is aligned with the stepped portion 2.
8, the spring receiving element 24 is rotated again to a position where its protrusion 23 faces the deep spline groove 19. As a result, the protrusion 23 engages with the deep spline groove 19 under the action of the spring 31, causing the spring receiving element 24 to retreat, thereby reducing the elastic force of the spring 31 acting on the detent element 30 accordingly. . When the elastic force of the spring 31 is reduced, the detent action of the detent element 30 is released and the handle 9 returns to its original position.

Since the handle device according to the invention is configured as described above, when the pushbutton is pressed to activate the knocking mechanism, the elastic force of the spring can be increased and applied to the detent element, so that the detent element can be moved into the recess. When the pushbutton is pressed to release the knocking action of the knocking mechanism, the elastic force of the spring is reduced to release the lock by the detent element of the handle. can. Therefore, the handle can be locked to the open position or unlocked with one-touch operation, which is very convenient for use as a handle device for a water tank for cold regions.
