Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a faucet-connected water sprinkling device that is connected to a faucet and sprays water from the faucet in a shower-like manner.

(Prior Art) The present applicant proposed such a water sprinkling device for connection to a faucet in Utility Application No. 167455/1983.

(Problems to be Solved by the Invention) In conventional water sprinklers, a hollow connecting part that is attached to a faucet is directly connected to a hollow head that sprays water in a shower-like manner. For this reason, normal faucets are somewhat vertical.
Since it is tilted towards you, if you attach it to a faucet, it will tilt in the same direction as the faucet and spray water diagonally, which can cause water to splash out of the kitchen sink or washbasin. Furthermore, if the water flow from the faucet is reduced, the water may no longer come out in a shower, or even if a propeller is provided in the hollow head that can be rotated by the water flow, the propeller may not rotate.

For this reason, it is also known to connect the hollow connecting part and the hollow head with a rubber tube, metal flexible tube, etc., but these rubber tubes and metal flexible tubes have flexibility, but cannot be oriented in a specific direction. Since the hollow head cannot be fixed in place, it is necessary to hold the hollow head in your hand and keep it pointing in the specified direction in order to spray water in a specified direction, so washing can only be done with one hand. What's more, it hangs from the faucet and can get in the way of your work.

(Means for Solving the Problems) Therefore, the present invention provides a hollow connecting part that fits and attaches to a faucet, a hollow head that sprays water like a shower, and a bellows tube that connects the hollow connecting part and the hollow head. The chevron-shaped cross-sectional joints of each stage of the bellows tube are composed of a pair of annular walls whose outer peripheral edges are connected by a hinge, and the length of the slope of one annular wall is equal to the slope of the other annular wall. It is characterized by being shorter than its length.

(Function) By partially bringing the pair of annular walls of some nodes of the bellows tube into close contact with each other in the circumferential direction, the bellows tube can be bent and fixed in any direction, and the hollow head can be moved in any direction with respect to the faucet. can be directed to. Also, by overlapping the annular walls of all pairs of nodes of the bellows tube, the length of the bellows tube is shortened.

(Embodiment) In the illustrated embodiment, 1 is a faucet, 2 is a hollow connecting portion, 3 is a hollow head, and 4 is a bellows tube.

The hollow connecting portion 2 includes a connecting tube 6 integrally equipped with a tapered tube 5 whose diameter decreases downward from the inner periphery of the upper end.
and inner and outer rings 7, 8 which pinch the bellows tube 4 whose upper end is fitted onto the inner periphery of the connecting tube 6 from the inside and outside on the lower surface of the connecting tube 6; It consists of the inner and outer rings 7, 8 and a retaining ring 9 which holds the upper part of the bellows tube 4 against the connection tube 6 by fitting an annular projection on the inner circumference into an annular groove on the outer circumference of the connection tube 6. If necessary, the surfaces of the connecting tube 6, the upper end of the bellows tube, and the rings 7, 8, and 9 that come into contact with each other are bonded with adhesive. The inner ring 7 has fan-shaped water holes 7' divided by a plurality of spokes extending radially from the center, and resists the force applied from the surroundings by the spokes 7a, the outer ring 8, and the retaining ring 9.

Further, the hollow head 3 has a transparent shell 11 whose lower surface is open and has a depression 10 in the center of the upper surface, and the shell 11
It has a water sprinkling plate 13 having a large number of holes 12 whose outer peripheral edge is fixed by gluing or the like on the lower surface of the recess 10.
is equipped with a plurality of fan-shaped water holes 14 divided by a plurality of spokes extending radially from the center. In this embodiment, a shaft projects downward from the center of the recess 10 and a shaft projects upward from the center of the water spray plate 13, and both of the shafts are connected to the blades 15 having a twist.
The propeller 16 protrudes from above and below into the central cylindrical portion 16' of the propeller 16, which has a plurality of cylinders surrounding the propeller 16, and rotatably supports the propeller 16 within the hollow body.

The bellows tube 4 is provided with knots 17 having a multi-stage chevron-shaped cross section in the vertical direction. Two nodes adjacent to each other in the vertical direction are each articulated by a hinge 18, and each node 17 has a pair of outer peripheral edges articulated by a hinge 19 that bends in the opposite direction to the hinge 18. It consists of upper and lower annular walls 20 and 21. Both annular walls 20,
21 are each rigid, and in this embodiment, the length l of the slope of the upper annular wall 20 is shorter than the length L of the slope of the lower annular wall 21.

The lower end of the bellows tube 4 is fixed between a ring 4' fitted on its inner circumference and the inner circumferential slope of the recess 10 of the hollow head. Of course, these mutually contacting surfaces may be bonded with an adhesive if necessary.

Figure 1 shows the state where the bellows tube 4 is fully extended, and the third
The figure shows the bellows tube shortened to its minimum size. In either state, when the tapered cylinder 5 of the hollow connecting part 2 is attached to the outer periphery of the faucet 1 and water is discharged from the faucet, the water passes through the bellows cylinder 4 and enters the hollow head 3, and the water enters the water sprinkling plate 13. The water flows out from the small holes 12 in a shower shape, and the propeller 15 rotates in the hollow head, and the rotation can be seen from the outside.

In particular, when the bellows tube 4 is shortened, the reason why the bellows tube 4 is not extended by water pressure is that the joints 17 of each stage of the bellows tube having a chevron cross section are connected at their outer peripheral edges by the hinges 19, as described above. two rigid annular walls 2
This is because the length l of the slope of one of the annular walls 20 is shorter than the length L of the slope of the other annular wall 21.

In other words, with this configuration, when the bellows tube 4 is shortened, the length of the slope of the node 17 of each stage, which had been slanted outward and upward, is shortened, and in this embodiment, the upper annular wall 20 is inverted downwardly beyond the surface surrounded by the upper circumferential edge of the hinge 19 or the lower annular wall 21, and is inverted obliquely upward inward and closely folded onto the lower annular wall 21 having a longer slope. (Figure 3). Therefore, if the bellows hangs downward from the faucet 1 for a long time and gets in the way, the bellows tube 4 can be pushed upward by holding the hollow head to shorten the downward length of the bellows tube. The shortened bellows tube does not expand even when the water pressure from the faucet is applied to the water sprinkling plate of the hollow head. Also, to extend the shortened bellows tube, hold the hollow head and pull it downward.

In this way, by folding the nodes 17 of all stages of the bellows tube 4 over the entire circumference, the length of the bellows tube is reduced to the minimum, but the annular wall 20 of the nodes 17 of one or some of the steps , 21 can be fixed by folding only a part of the circumference as described above (Fig. 4), instead of the entire circumference, the bellows tube 4 can be swung in any direction and the You can also sprinkle water on it. For example, when the faucet 1 is tilted toward the front, the bellows can be slightly tilted backwards to level the sprinkler plate, and even if the amount of water that comes out of the faucet is small, it can be sprayed in a shower-like manner, and the propeller 16 can be rotated smoothly. Also, water can be sprayed in a specific direction. In this case, the bellows tube stands on its own in a bent state and does not deform even under water pressure, so unlike the case of rubber tubes or flexible metal tubes, there is no need to support it with your hands, so you can work with both hands.

In this embodiment, the length of the upper slope of the pair of annular walls 20 and 21 constituting the nodes of each stage of the bellows tube is shorter than that of the lower slope, and conversely, the length of the lower slope is shorter than that of the upper side. You can.

(Effects of the invention) According to the invention, it is possible to connect the faucet with a hollow connection part, and to shorten the extending bellows tube against water pressure so that it does not get in the way, or to bend it in a swinging manner to connect the hollow head to the faucet. It is possible to provide a faucet-connected watering device that can direct water in a predetermined direction.
