Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a switch for opening and closing antifreeze faucets.

(Conventional technology) Water faucets are installed indoors to protect them from the cold, but since faucets are installed for each indoor water supply system, many are installed together under the floor. Therefore, many handles for opening and closing operations will also be placed indoors. By the way, since having this handle protruding from the floor would be a nuisance in daily life, the applicant filed the utility model registration application No. 1 in 1981.
In No. 16314 and Utility Model Application No. 16315 filed in 1959, they proposed an idea to position the handle on the floor. In the former case, the handle is housed inside the floor with the handle substantially flush with the floor surface, and the handle is made to protrude above the floor using spring pressure through a protruding means. The lid is opened and the handle is pulled up, so that the handle is exposed above the floor only when the faucet is opened or closed. The present invention relates to an improvement on the former method, but although the former method is convenient because the handle can be easily protruded with a fingertip, it has drawbacks such as a complicated and high cost means for protruding and storing the handle.

(Problems to be Solved by the Invention) The present invention aims to reduce costs by simplifying the structure of the protruding housing means of the handle, and to provide a less expensive antifreeze faucet switch.

(Means for Solving the Problems) The present invention has a handle projecting storage means having the following configuration. That is, the structure is such that an engager is engaged with the handle tube integral with the handle so that rotation can be freely transmitted and the engager can be slid up and down. A hollow shaft, which is rotatably fitted into the handle pipe and integrally raised and lowered, is removably engaged with the engager while being pressed upward with a spring while restricting protrusion, and the engager is pushed upward with a spring. The lower end of the joint is connected to a universal joint.

(Function) According to the above configuration, the handle protruding storage means is disposed at the center of the handle, so the switch itself becomes compact.

(Example) To explain the present invention based on an example, as shown in Fig. 1, an antifreeze water faucet c buried under the indoor floor is installed on a floor d via a telescopic connecting rod b. The antifreeze water faucet of the present invention is opened and closed by the switch a (hereinafter referred to as switch a), and when opening and closing, the handle 1 protrudes above the floor d, and when not in use, the handle 1 is It is pushed down and stored in case 2 of switch a. In detail, as shown in Fig. 2, the case 2 is fixed to the upper surface of the floor at the flange portion 3, a concave storage seat 4 is provided at the center of the upper part, a through hole 5 is provided at the center of the bottom surface of the seat 4, and a through hole 5 is provided at the bottom of the seat 4. holds a cylinder 6 having the required inner diameter. The handle 1 has a circular seat 7 dug in the center of the top surface,
A small hole 8 is formed through the center of the bottom of the seat 7, and the handle 1
A handle tube 9 made of a square pipe hangs down from the lower surface of the handle tube 9 with screws around the small hole 8, and a square shaft 26 having an engager 10 pinned to the lower end thereof is fitted into the handle tube 9. The engager 10 has a semi-circular groove 1 on the circumference of the shaft.
1 is provided around the periphery, and a round shaft 12 integrated with a square shaft 26 is provided at the bottom.
The seat plate 1 hangs down and is locked to the lower end of the cylinder 6.
3 in a slidable manner, and one end of a universal joint 14 is locked at the lower end. One end of the spring 15 is locked to the lower part of the engaging element 10, and the other end of the spring 15 is locked to the seat plate 13. A hollow shaft 16 that is rotatably fitted to the handle pipe 9 and integrally raised and lowered is guided into the through hole 5 with its upper end in close contact with the lower surface of the handle 1, has a flange 17 around its lower part, and has the other end attached to a seat plate. 1
One end of the spring 18 that is locked to the flange 1
7, a slit 20 consisting of a vertical groove is provided in the cylindrical elastic portion 19 as required from the lower surface to the lower end as shown in FIG. A constricted portion 21 is formed by bending the tip into a semicircular arc shape, and the constricted portion 21 is removably engaged with the groove 11 of the engaging element 10. Further, the head 23 of the push button 22 is mounted on the seat 7 in the center of the handle 1.
A leg 24 integral with the head 23 is inserted into the small hole 8 to prevent it from coming off, and the lower end of the leg 24 is made to correspond to the top of a square shaft 26 integral with the engaging element 10. In this case, the top surface of the head 23 of the push button 22 is aligned with the top surface of the case 2, and the bottom surface of the head 23 and the bottom surface of the seat 7 have a space 2 formed by a predetermined stroke.
5 is provided.

When opening and closing the antifreeze faucet with the above-described configuration, the handle 1 may be caused to protrude from the storage seat 4 of the case 2 by pushing down the push button 22. That is, by pressing the head 23 of the push button 22 with a fingertip, the leg 24 pushes down the engager 10 via the top of the square shaft 26, and as a result, the engager 10
A groove 11 provided around the shaft periphery of the hollow shaft 16 is a constricted portion 2 of the hollow shaft 16.
1 and the hollow shaft 16 is lifted upward by the spring 18, so that the handle 1 also protrudes upward from the storage seat 4. When the handle 1 is opened or closed, that is, when it is rotated in one direction, the handle tube 9 is also rotated, and the round shaft 12 is also rotated via the square shaft 26, and the rotation is transmitted to the universal joint 14 at the lower end of the connecting rod b. The antifreeze faucet c is opened and closed via the .

After the opening/closing operation of the antifreeze faucet c is completed, when the handle 1 is pushed down, the hollow shaft 16 also lowers together, and when the handle 1 is seated on the storage seat 4, the constricted portion 21 at the lower end of the hollow shaft 16 fits into the groove of the engager 10. 11 and is locked against the reaction force of the spring 18, and the engager 1
0 is restrained by a seat plate 13 that is secured to the lower end of the cylinder 6 via a universal joint 14 joined to the lower end of the round shaft 12, and its upward protrusion is restricted. Stored and kept. Furthermore, the present invention can also be used to open and close an anti-freeze faucet c buried outdoors as shown in FIG. In this case, the case 2 is attached to the wall surface e using the flange portion 3 and operated in the same manner as described above.

(Effects of the invention) Since the protruding storage means of the handle is constructed around the handle shaft, the case itself is compact and assembly is easy, reducing costs and providing an inexpensive switch.
