Description

Lever Limiting Apparatus for faucet

The present invention relates to a lever limiting device of the faucet, and more particularly to a lever limiting device of the faucet capable of preventing burns due to sudden discharge of hot water by limiting the rotation angle of the lever for controlling the mixing amount of hot water and cold water. It is about.

In general, a faucet installed in a wash basin or a bathtub of a kitchen or a bathroom is configured to discharge the hot water or cold water, a mixture of hot water and cold water by adjusting the discharge amount of the mixed water and the mixed water according to a manipulation of the handle, and the hot water or The cartridge which controls the discharge amount of the mixed water of cold water and cold water, and mixed water is comprised.

Conventionally, such a cartridge has a lower plate 11 having a discharge port 11a through which mixed water is discharged and a plurality of inlets 11b through which cold water and hot water are introduced, as shown in FIG. 1. .

On the upper side of the lower plate 11, a lower disk 12 having passages 12a and 12b communicating with the discharge port 11a and the inlet 11b is seated inside the case 10.

A packing 13 is interposed between the lower disk 12 and the lower plate 11, and the hot disk and the hot water introduced through the inlet 11b and the passage 12b pass through the lower disk 12. An upper disk 14 having a communication path 14a for discharging to the 12a and the discharge port 11a is seated so as to be slidable.

The lower disk 12 is limited in rotation in the circumferential direction by a plurality of protrusions 11c protruding upward of the lower plate 11.

A seat cap 15 is coupled to an upper side of the upper disk 14, and a bush 16 inserted into an upper inner side of the case 10 is rotatably coupled to an upper side of the seat cap 15. The lever 17 is hinged to the inside of the bush 16 by a pin 17a so as to be pivotable at an angle in a forward and backward direction, and the lower end of the lever 17 is an upper end of the seat cap 15. It is configured to be coupled to and operate integrally.

On the upper side of the lever 17, the handle 18, which the user can operate forward, backward, left and right, is fastened by a screw 19.

Therefore, when the user operates the handle 18 in the forward and backward directions, the lever 17 is rotated around the pin 17a to slide the seat cap 15 and the upper disk 14 forward and backward. Accordingly, the amount of water introduced through the inlet 11b is determined as the amount of water discharged through the outlet 11a according to the degree in which the communication path 14a of the upper disk 14 communicates with the passage 12b.

When the handle 18 is rotated in the left and right directions, the bush 16 coupled to the lever 17 and the pin 17a and the seat cap 15 coupled to the front end of the lever 17 and the The upper disk 14 coupled with the seat cap 15 is rotated integrally, according to the degree of communication of the communication path 14a and the passage 12b communicated with the inlet port 11b of cold and hot water. The ratio of hot water is determined so that the mixed water is discharged through the passage 12a and the discharge port 11a.

However, such a conventional faucet is easy and convenient to control the amount of mixed water and the amount of discharged water mixed with a single lever, while in the case of the elderly or children who are not familiar with the operation of the lever, only hot water is used. If the lever is operated to be discharged, there is a risk of burns due to rapid discharge of hot water, and especially the danger of the group is increased in the case of a group living space or a large family, such as a hospital or kindergarten.

Therefore, the present invention is devised to solve the above-described problems of the prior art, and an object of the present invention is to limit the amount of rotation of the lever, in particular, the amount of discharge of hot water, to limit the amount of rotation of the lever in advance to prevent accidents such as burns. It is to provide a lever limiting device of the faucet that can be prevented in advance.

The lever limiting device of the faucet according to the present invention for achieving the above object, in the cartridge assembly having a case, a bush rotatably coupled to the inside of the case, and a lever hinged to the bush, the cartridge The upper side of the assembly is characterized in that the rotation limiting member for limiting the amount of rotation of the lever is detachably coupled.

Therefore, in the present invention, the amount of hot water discharged is limited by the rotation angle of the lever limited by the rotation limiting member detachably coupled to the upper side of the cartridge assembly, and thus, the hot water discharge is suddenly caused by immature operation or mishandling of the handle. The occurrence of safety accidents such as burns is prevented in advance.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Figure 2 is an exploded perspective view showing a cartridge applied to the lever limiting device of the faucet according to the present invention, Figure 3 is a coupling cross-sectional view showing a coupling state of the present invention, the same reference numerals and the same name for the same configuration as the conventional configuration. The detailed description thereof is omitted.

Reference numeral 20 in the drawing denotes a cartridge assembly.

A plurality of outward protrusions 21 protrude from the outer circumferential surface of the case 10 constituting the cartridge assembly 20, and the bush 16 and the lever 17 of one side of the bush 16 are protruded. A locking projection 22 for limiting the amount of rotation is formed to protrude.

And, the upper surface of the case 10 has a reference protrusion 23 is formed to protrude, the reference protrusion 23 is a reference for determining the degree of limitation when limiting the amount of rotation of the lever 17.

On the other hand, the upper side of the case 10 is coupled to the rotation limiting member 30 for limiting the amount of rotation of the lever 17 and the bush (16).

The rotation limiting member 30 has a plurality of inward protrusions 31 coupled to the outward protrusions 21 protruding from the inner circumferential surface thereof, and the locking protrusions 30 to limit the amount of rotation of the lever 17 thereon. 22 is provided with a latching jaw 32 to be caught.

In addition, a display window 33 in which the reference protrusion 23 is positioned is formed at one side of the locking jaw 32 so as to know the degree of limitation of the lever 17, and is separated from the outside of the rotation limiting member 30. Alternatively, a plurality of grooves 34 are formed to prevent slippage or the like upon coupling.

The rotation limiting member 30 may vary an engagement angle according to the degree of rotation limitation of the lever 17. For example, when the reference protrusion 23 is coupled to the leftmost side of the display window 33, the lever 17 is rotated. The amount of rotation is limited to a minimum, and on the contrary, when the reference protrusion 23 is coupled to be located at the rightmost side of the display window 33, the amount of rotation of the lever 17 is limited to the maximum.

The lever limiting device of the faucet according to the embodiment of the present invention configured as described above is limited by the degree of rotation of the lever 17 by coupling the rotation limiting member 30 to the upper side of the cartridge assembly 20, thereby reducing the discharge amount of hot water. Will be limited.

That is, when the limiting degree of the lever 17 is reduced when the rotation restricting member 30 is coupled to the cartridge assembly 20, the reference protrusion 23 protruding thereon is positioned on the left side of the display window 33. When the rotation limiting member 30 is coupled and, on the contrary, the limiting degree of the lever 17 is to be increased, the rotation limiting member 30 may be coupled so that the reference protrusion 23 is positioned on the right side of the display window 33. .

When the pivot restricting member 30 is coupled to the upper side of the cartridge assembly 20 so that the reference protrusion 23 is positioned at an appropriate position of the display window 33, the outward protrusion 21 and the inward protrusion 31 are fixed to each other. State is maintained.

At this time, as shown in FIG. 4 (a), when the lever 17 is rotated from the neutral position of hot water and cold water to the hot water side as shown in FIG. When the locking projection 22 that is rotated after a predetermined angle is caught by the locking jaw 32 of the rotation limiting member 30, the rotation operation of the lever 17 is restricted.

Therefore, in this state, the hot water is discharged by a certain amount or more by the operation of the locking projections 22 caught by the locking step 32, and thus the hot water is suddenly discharged due to a mistake in the handle operation. As a result, safety accidents such as burns caused by rapid discharge of hot water are prevented.

In addition, when changing the discharge amount of hot water during use, if the rotation limiting member 30 is removed from the cartridge assembly 20 and the position of the reference protrusion 23 shown in the display window 33 is changed, it is often necessary to change the discharge amount of the hot water. It becomes possible.

In this embodiment, the outward protrusion 21 is formed above the case 10 of the cartridge assembly 20, but is not limited thereto. As illustrated in FIG. 5, the cover 40 may be disposed above the case 10. In the case of the cartridge assembly 20 coupled to the cover 40, the outward protrusion 21 may be formed to couple the rotation limiting member 30, of course.

As described above, according to the present invention, the rotation angle of the lever is limited by the rotation limiting member detachably coupled to the upper side of the cartridge assembly, thereby limiting the amount of hot water discharged, and thus, by the immature or mishandling of the handle. The occurrence of safety accidents such as burns caused by rapid hot water discharge is prevented in advance.
