Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water supply joint suitable for attachment to, for example, a washing machine.

In conventional water supply fittings, the connection part of the water supply hose is straight, so if there is a narrow distance between the water faucet and the sink or washbasin, the hose may come into contact and bend, causing excessive force to be applied to the connection part. However, there were problems with water leaking. In addition, when attaching and detaching the connections before and after use in such conditions, it is not easy to do so, and if the connection is not complete, it may come off during use, causing problems such as water overflowing. .

The purpose of the present invention is to prevent the hose fitting from bending or connecting when the water supply fitting is attached to a water faucet in a sink or washbasin, and when the space between the water tap and the tap is narrow, the end face of the hose fitting hits the washbasin with a conventional straight fitting. If excessive force is applied to the parts, there is a risk of problems such as water leakage or connection parts coming off. Therefore, an attempt is made to provide a joint that eliminates water leakage and disconnection and allows reliable connection.

In the present invention, a faucet support 1 is fixed to a faucet 2 with a stopper such as a set screw 3, a threaded portion 5 is formed on the outer periphery of the faucet support 1, and a fastener 7 is attached to the threaded portion. By screwing them together, the packing 6 is sandwiched between the upper end of the fastener 7 and the opening edge of the water faucet 2, and a tapered groove 9 is formed on the lower outer periphery of the fastener 7, forming an L-shape. A fitting coupling portion 17 including a slide ring 16 is provided at the upper end which is the open end of the connector 12 forming the
This fitting joint 17 is provided with a plurality of balls 10, a compression spring 15 that always urges the slide ring 16 to move upward, and an annular spring 14 that prevents the slide ring 16 from jumping out upward. By providing and attaching the upper end of the connector 12 to the lower part of the fastener 7, the ball 1 of the mating joint 17
0 engages with the tapered groove 9 to connect the fastener 7 and the connector 12, and the outer periphery of the right end, which is the other open end of the connector 12, has a taper similar to the tapered groove 9 of the fastener 7. A hose joint 20 in which a concave groove 9 is formed and a water supply hose 19 is fixed with a hose attachment part 18 is provided with a fitting joint part 17 that is removably connected to the other open end of the connector 12. Like the fitting connection part 17 provided at the upper end of the connector 12, the fitting connection part 17 is composed of a slide ring 16, a ball 10, a compression spring 15, and an annular spring 14, and has the same dimensional relationship. The water supply fitting is characterized by:

An embodiment of the water supply joint of the present invention will be described below with reference to the drawings. A faucet support 1 is fixed to a faucet 2 via a set screw 3, and a recess 4 and a threaded portion 5 are formed on the lower outer periphery of the faucet support 1. A fastener 7 is provided below the faucet support 1 with a packing 6 interposed at the opening edge of the faucet 2, has a hollow part, and has a protrusion 8 that engages with the recess 4 of the faucet support 1. is screwed and fixed by the screw 5 portion of the faucet support 1. In addition, a connector 1 is attached to the lower outer periphery of the fastener 7.
A fitting joint 17 formed at one open end of 2
A tapered groove 9 into which a ball 10 can be inserted is formed. The connector 12 is formed in an L shape,
The fitting joint portion 17 includes a plurality of balls 10 provided on the outer periphery of the fitting portion, a slide ring 16, a compression spring 15 attached to urge the slide ring 16 to always move upward, and a slide. It consists of an annular spring 14 attached to the annular groove 13 to prevent the ring 16 from popping upward. The fitting joint part 17 has a rubber seal 11 interposed on its inner periphery, and when it is attached to or detached from the fastener 7, the slide ring 16 is pressed down against the tension of the compression spring 15. ball 10
The position is maintained and fixed.

The outer periphery of the other open end of the connector 12 is formed to have exactly the same shape and dimensions as the part where the tapered groove 9 of the fastener 7 to which the fitting joint part 17 of the connector 12 can be detachably attached is formed. has been done. Then, connect the water supply hose 19 to the hose attachment part 18.
Connector 12 is attached to hose joint 20 fixed to
A fitting coupling part 17 having exactly the same shape and size as the fitting coupling part formed at the opening end of the opening is formed.
Therefore, the fitting connection portion 17 formed on the hose joint 20 can be directly fitted and connected to the fastener 7 and can also be fitted and connected to the connector 12.

Since the water supply joint of this embodiment is configured in this way, if there is a sufficient distance between the water faucet 2 and the sink or washbasin, the hose joint 20 can be directly attached to the fastener 7 and used. If the distance H between the lower end of the water faucet 1 and the upper surface of the sink 21 is small, the connector 12 can be attached between the fastener 7 and the hose joint 20. Therefore, when connecting the hose joint 20, no excessive force is applied to the hose joint 20, the operation of attaching and detaching is simple and easy, and the connection can be ensured without coming off during use or leaking water.

As described above, the present invention fixes the faucet support 1 to the faucet 2 with a stopper such as a set screw 3, forms a threaded portion 5 on the outer periphery of the faucet support 1, and forms the threaded portion 5 on the outer circumference of the faucet support 1. By screwing together the fastener 7, the packing 6 is sandwiched between the upper end of the fastener 7 and the opening edge of the faucet 2, and a tapered groove 9 is formed on the lower outer periphery of the fastener 7. A fitting joint 17 including a slide ring 16 is provided at the upper end, which is the open end of the L-shaped connector 12. A plurality of balls 10 are provided in the fitting joint 17, and the slide ring 16 is A compression spring 15 is provided that always urges the slide ring 16 to move upward, an annular spring 14 is provided that prevents the slide ring 16 from popping out upward, and the upper end of the connector 12 is attached to the lower part of the fastener 7 to ensure that the The ball 10 of the coupling portion 17 engages with the tapered groove 9 to connect the fastener 7 and the connector 12, and the outer periphery of the right end, which is the other open end of the connector 12, has a tapered recess of the fastener 7. A hose joint 20 in which a tapered groove 9 similar to the groove 9 is formed and a water supply hose 19 is fixed with a hose attachment part 18 has a fitting connection that is detachably connected to the other open end of the connector 12. Similar to the fitting coupling part 17 provided at the upper end of the connector 12, this fitting coupling part 17 is composed of a slide ring 16, a ball 10, a compression spring 15, and an annular spring 14, and has a dimensional relationship. There is also a water supply joint characterized in that it is also formed in the same manner.

According to this configuration, the following effects can be expected.

It can be easily used even in places where there is a narrow space between the water faucet and the washbasin, and since no undue force is applied to the hose joint, a secure connection can be made without any prying force.

The fasteners and hose joints can be easily attached and detached with one touch.

Since the fitting portion on the connector side and the fitting portion on the hose joint side have the same structure, productivity is high.
