Description

Upper fixing type sink faucet {An Upper fixing type sink faucet}

The present invention breaks away from the conventional mounting method in which a person stretches out his or her hand in the narrow space below the sink and tightens and fixes the tightening nut to the extension pipe at the bottom of the faucet body, inserts an anti-rotation bracket into the faucet insertion hole at the bottom of the sink, and inserts an O-ring at the top of the sink. After screwing the extension tube at the bottom of the faucet body to the anti-rotation bracket from the upper side of the sink in a state where the anti-rotation bracket does not fall down, screw the faucet body in the direction toward the sink and finally tighten the nut to tighten the faucet. It is designed to be installed quickly and easily.

In general, a sink faucet is used by forming through-holes vertically on one side of a sink bowl of a sink and fixing a faucet body there. After inserting an extension tube formed at the bottom of the faucet body into the through-hole, It consists of a method of fixing by fastening a tightening nut.

On the other hand, most of the through-holes for installing the faucet in the sink are installed in the rear center or one corner of the sink bowl, so the depth of the sink bowl is deep and the wall of the sink bowl and sink are close, so the operator is squatting without using their hands or a tightening tool. Not only is it very inconvenient to completely fasten the tightening nut to the end, but if the tightening nut is not perfectly fastened, the fixed state of the faucet is loosened shortly after, resulting in a situation in which the faucet shakes.

Conventionally, in order to solve the above problems, that is, methods for simply and firmly fastening a faucet mounted on a sink or washbasin have been proposed, and Patent Documents 1 to 4 below are representative examples.

The 'faucet fixture' in Patent Document 1 is also intended to conveniently fix the faucet to a sink or washbasin, but this is a method of tightening using a cam-type fastener, and can be conveniently installed when there is relatively little space under the sink or washbasin. However, there is a problem in that it cannot be applied when the space between the sink bowl and the wall is narrow or the depth of the sink bowl is deep.

The 'sink faucet wrench' of Patent Document 2 was developed for tightening nuts in hard-to-reach areas, which is located in a narrow space such as a sink and makes it difficult to tighten and loosen the nut while the hose is installed in the center. It was developed to solve the problem, but there was a problem that compatibility was difficult when the specifications of sink faucets were different.

The 'fixture enabling faucet installation from the top' of Patent Document 3 is to provide easy and convenient assembly of the faucet when the faucet is mounted on a sink or washbasin. Installation of the faucet is easy because it is made in such a way that the faucet is fixed on the ring body by fastening the faucet on the ring body by inserting the faucet on the ring body and then fastening the no-bolt type key from the side after fixing the screw with the fastener placed on the lower side. However, there was a problem that the mounting structure of the faucet was not very sturdy, and the appearance was not neat.

In the 'faucet fixing structure' of Patent Document 4, an unthreaded extension is formed on the inner circumferential surface of the nut member upward, so that when the nut is screwed into the extension pipe of the faucet, the extension pipe can be fixed to the sink even if the nut member is rotated less. However, it is also difficult to firmly fix the faucet to the sink in a situation where the space is narrow because the nut must be firmly tightened from the bottom.

In addition, the above problem occurs not only in the sink but also in the washbasin in the bathroom.

In order to solve this problem, the present applicant has developed an 'upper clamping type sink faucet' as Patent Document 5, which still requires almost an operation of screwing a nut to the male threaded portion of the extension pipe of the faucet body at the bottom of the sink. Since the tightening work was supposed to be finished by turning the tightening ring at the top of the sink, there was still a hassle that the operator had to stretch his hand under the sink and tighten it while squatting uncomfortably to tighten the nut.

In addition, the present applicant has developed an 'upper fastening type sink faucet' with an improved structure in Patent Document 6, but the size of the faucet hole formed in the sink is not standardized and is large or small so that the elastic hook of the anti-rotation bracket is not caught. Since the faucet body is supported by the fastening action caused by the occurrence of a situation or the opening of the extension foot of the extension ring, there is a concern that a situation in which the bearing capacity is reduced in the process of use may occur.

The male screw ring is screwed and fixed to the female screw part of the lower part of the faucet body, and the tightening nut is combined with the key of the middle part of the extension pipe so that the male screw part of the lower part of the extension pipe is fastened to the female screw part formed in the anti-rotation bracket of the lower part of the sink. An upper tightening type sink faucet is provided in which the faucet body is fixed to the sink while the tightening nut is in close contact with the upper surface of the sink by additionally rotating the extension tube by tightening the tightening nut.

In a preferred embodiment, the anti-rotation bracket is composed of a plate body portion having a locking wing to prevent rotation by being caught on a corner portion of a sink or the like, and a protruding single pipe at an upper portion of the plate body portion.

According to the present invention, when installing a faucet in a sink or washbasin, the extension tube is added to the anti-rotation bracket simply by inserting the anti-rotation bracket from the bottom of the sink or washbasin insertion hole, inserting the faucet body into the bracket from the top, and then tightening the tightening nut. By screwing together, the tightening nut adheres to the upper surface of the sink or washbasin, allowing the faucet body to be firmly installed on the sink, etc., thus eliminating the inconvenience and hassle of having to tighten the tightening nut in an uncomfortable position in the narrow space below the sink. In addition, it has a useful effect of easily removing and inspecting or replacing the faucet when necessary.
