Description

The present invention relates to a hose joint that is mainly used in horticulture, agriculture, and cleaning at home and the like to connect a hose and another device to allow fluid to pass through.

A hose joint is another device that connects a hose to one end and supplies or receives a liquid such as another hose, water faucet, watering nozzle, or hose reel to the other end (hereinafter, simply "other device"). It is a hollow device that connects a hose to another device to allow fluid to pass through.
Devices used for watering such as these watering nozzles and hose reels are hereinafter referred to as "watering devices".
Further, in the hose joint, the side where the hose is connected is called the tip side, and the opposite direction is called the base end side.

As shown in FIG. 6, Patent Document 1 describes a hose connection with a joint body 24 having a tubular hose connecting pipe portion 24a that is connected to another device on the proximal end side and can be inscribed in the hose H on the distal end side. A claw member 25 arranged on the outer peripheral side of the pipe portion 24a and provided with a restraining claw 28a on the inner circumference capable of pressing the hose H in the radial direction, and arranged on the outer peripheral side of the hose connecting pipe portion 24a and the claw member 25. Then, the joint body 24 is fitted on the base end side so that the position of the joint body 24 can be adjusted deeply and shallowly in the pipe direction, and a reduced diameter opening 30a having a diameter larger than that of the hose H and a diameter smaller than that of the claw member 25 is provided on the tip side. A hose joint 21 with a lock nut 26 is described.

In this hose joint 21, the claw member 25 has a claw member stopper 29 fixed in the pipe direction to the lock nut 26 and a restraining claw 28a, and is movable and detached from the claw member stopper 29 in the pipe direction. It consisted of a claw member main body 28 that was attached so as not to be attached.
Further, the restraint claw 28a was formed on the tip side of the claw member 25 in the pipe direction, that is, on the hose attachment side of the hose joint 21.

In order to connect the hose H to the hose joint 21 of Patent Document 1, as shown in FIG. 6B, the lock nut 26 is arranged on the outer peripheral side of the joint body 24, and then the hose H is connected to the hose connecting pipe portion 24a. When the lock nut 26 is fitted to the joint body 24, the reduced diameter opening 30a of the lock nut 26 comes into contact with the restraining claw 28a from the tip side, and the restraining claw 28a is along the reduced diameter opening 30a. The hose H was elastically deformed inward in the radial direction, and the hose H could be strongly brought into close contact with the hose connecting pipe portion 24a.

When the hose H is removed from the state of being connected to the hose joint 21, as shown in FIG. 6A, the lock nut 26 is rotated to bring it into a shallow fitting state, so that the restraint claw 28a and the diameter reduction port 30a are formed. A gap is formed between the two, and the hose H is pulled to remove it from the hose connecting pipe portion 24a.
However, the restraint claw 28a is formed on the tip end side of the claw member main body 28, the reduced diameter opening 30a of the lock nut 26 is arranged on the tip end side of the restraint claw 28a, and the restraint claw 28a (claw member main body). Since 28) is movable in the pipe direction with respect to the lock nut 26, when the hose H is pulled out, the restraining claw 28a moves to the tip side together with the hose H by frictional force and hits the reduced diameter opening 30a again. In contact with the hose H, the hose H is pressed inward in the radial direction along the inclination of the reduced diameter opening portion 30a, which may make it difficult to remove the hose H.

Further, when the hose H is pressed against the hose connecting pipe portion 24a by the restraint claw 28a, the hose H may bulge outward in the radial direction on the tip side from the position. Therefore, in order to suppress the swelling of the hose H, the lock nut It was preferable to provide a long tubular hose retainer 30b on the tip side of the reduced diameter portion 30a of 26.

According to the first invention, if the claw member is fixed to the lock nut in the pipe direction so that the lock nut is in a shallow fitting state, the restraining claw is surely separated from the diameter reduction opening portion. The restraining claw is formed on the base end side of the claw member, and the joint body is provided with a reduced diameter opening portion having a diameter larger than that of the hose and a diameter smaller than that of the claw member, and the joint body and the lock nut are shallow. In the mated state, the reduced diameter opening is located closer to the base end than the restraining claw, so even if the restraining claw bends toward the tip side due to frictional force when the hose is pulled, the reduced diameter opening Rather away from the part, the hose can be easily removed. Further, in the deeply fitted state between the joint body and the lock nut, the restraining claw can press the hose along the reduced diameter opening portion, so that the fitted state between the joint body and the lock nut can be operated. You can easily press the hose just by doing so.

According to the second invention, the restraint claw is elastically deformed in the radial direction by holding the restraint claw rotatably in the circumferential direction in a shallow mating state between the joint body and the lock nut.

It is sectional drawing of the conventional hose joint, (a) shows a shallow fitting state, (b) shows a deep fitting state.

Hereinafter, the hose joint according to the present invention will be described.
The hose joint 1 is a device that connects a hose and another device to allow fluid to pass through, and connects a hose to another hose as shown in FIG. 1 (a), as shown in FIG. 1 (b). As shown in FIG. 1 (c), the hose and the faucet are connected, the hose is attached to the watering nozzle 2 and connected to the hose as shown in FIG. 1 (c), and the hose H of the hose reel 3 and water are sprinkled as shown in FIG. A wide variety of things are included, such as those that connect to the nozzle 2.

Hereinafter, as an embodiment of the present invention, a hose joint 1 for connecting a hose and a faucet as shown in FIG. 1B will be described.
As shown in FIG. 2, the hose joint 1 has a joint body 4, a claw member 5, and a lock nut 6.
The joint body 4 of the hose joint 1 is a hollow member to which the hose H (see FIG. 5B) can be connected to the tip and the other end can be connected to another device (not shown). The fluid can be passed between the hose H and the other device.
Hereinafter, the side of the hose joint 1 to which the hose H is attached is referred to as the tip end side, and the opposite direction is referred to as the base end side.

As shown in FIGS. 2 and 5, a tubular hose connecting pipe portion 4a having an outer diameter that can be inscribed in the hose H is formed at the tip of the joint body 1. The inner peripheral surface of the hose connecting pipe portion 4a may be appropriately provided with ribs to reinforce it.
An outer cylinder 4b is provided around the outside of the hose connecting pipe portion 4a. A male screw portion 7a for screw connection to the lock nut 6 is formed on the outer peripheral surface of the outer cylinder 4b.

Further, at the tip of the outer cylinder 4b, a diameter-reduced opening portion 4c whose inner diameter gradually decreases toward the base end side is formed. The tip of the reduced diameter opening 4c has a larger diameter than the restraining claw 8a of the claw member 5 described later, and the base end of the reduced diameter opening 4c is formed to have a smaller diameter than the restraining claw 8a.

As shown in FIGS. 2 and 5, the claw member 5 is formed by integrally combining a substantially annular claw member main body 8 and a claw member stopper 9.
As shown in FIG. 3, the claw member main body 8 is a member that meanders up and down and is formed in an annular shape in a plan view. A restraining claw 8a is formed at the upper end portion of the hose joint 1 facing the base end side.
The restraint claw 8a is formed by projecting two upper and lower ridges inward in the radial direction from the inner peripheral surface of the claw member main body 8. Twelve restraining claws 8a are formed at equal intervals on the circumference.
Due to such a shape, the claw member main body 8 is easily elastically deformed in the radial direction, and the restraining claw 8a is also easy to swing in the radial direction.
The number of ridges of the restraint claws 8a that hold down the hose is not limited to one or more, but the molding of the restraint claws 8a requires undercutting on the mold, so it is necessary to remove the mold by forcibly removing the hose. If it exceeds the above, there is a risk that it will not be possible to forcibly remove the hose during molding, so 5 or less is particularly preferable. In the embodiment of the present invention, two ridges are provided.
Further, if the protruding length of the ridge of the restraint claw 8a in the radial direction is less than 0.2 mm, the hose holding force when pressing the hose H is weak, and the hose H may easily come off when water pressure is applied. Therefore, 0.2 mm or more is preferable, and 0.3 mm or more is particularly preferable. Further, if it exceeds 1.8 mm, the outer diameter of the restraint claw 8a needs to be increased accordingly, and the size of the device becomes large. Therefore, 1.8 mm or less is preferable, and 1.2 mm or less is particularly preferable. In the example, it was set to 0.5 mm.
If the length of the claw member main body 8 in the pipe direction (axial direction) is less than 3 mm, it becomes difficult to elastically deform in the radial direction, and when pressing the hose H, a force for pressing with the lock nut 6 is required, so that the length is 3 mm or more. Is preferable, and 6 mm or more is particularly preferable. Further, if it exceeds 20 mm, the size of the device becomes large and the amount of movement (operation amount) of the lock nut 6 required to provide an escape allowance when releasing the pressing of the hose H becomes large and the operability deteriorates. The following is preferable, and 15 mm or less is particularly preferable. In the example, it was set to 12.4 mm.
As the material of the claw member main body 8, an elastic resin is preferable, and a PP (polypropylene) resin is particularly preferable because of its excellent hinge characteristics. In the embodiment of the present invention, PP resin was adopted.

As shown in FIG. 4, the claw member stopper 9 is a component formed in an annular shape having a diameter inscribed in the claw member main body 8, and 12 positioning protrusions 9a projecting outward in the radial direction are provided at equal intervals on the circumference. ing.
The positioning protrusion 9a penetrates a groove formed between the restraining claws 8a of the claw member main body 8 and is fixed to a lock nut 6 described later at the outer end.
Resin, metal, or the like can be used as the material of the claw member stopper 9, and resin is preferable because it is inexpensive. Among them, PP resin is particularly preferable because it is particularly inexpensive. In the embodiment of the present invention, PP resin was adopted.

To assemble the claw member 5, the positioning protrusion 9a of the claw member stopper 9 is fitted into a groove formed between the restraining claws 8a of the claw member main body 8, and the claw member stopper 9 is inside the claw member main body 8. Get in touch. At this time, the restraining claws 8a and the positioning protrusions 9a are alternately arranged in the circumferential direction of the claw member 5.
In the state where the claw member 5 is assembled, the restraint claw 8a is formed on substantially the entire circumference, but the claw member main body 8 is easily elastically deformed in the radial direction due to the gap between the restraint claws 8a, and each restraint member 5 is easily deformed. The claw 8a is likely to swing in the radial direction.
The number of deterrent claws 8a arranged in the circumferential direction may be one or a plurality, and is not limited. In the embodiment of the present invention, the number is 12.
When a plurality of restraint claws 8a are provided, it is preferable to arrange them at equal angle positions on the circumference in order to evenly tighten the entire circumference of the hose.
The claw member 5 is arranged on the outer peripheral side of the hose connecting pipe portion 4a in the hose joint 1.

As shown in FIGS. 2 and 5, the locknut 6 is attached to a tubular locknut main body 10 capable of covering the hose connecting pipe portion 4a and the outer peripheral side of the claw member 5, and a male screw portion 7a of the joint main body 4. The female screw portion 7b to be screwed is joined to the locknut screw portion 11 formed on the inner peripheral surface by ultrasonic welding.
The lock nut screw portion 11 is formed to have an outer diameter inscribed in the inner peripheral surface of the lock nut main body 10, and the base end portion is projected outward in the radial direction so that the base end portion cannot be inserted into the lock nut main body 10. By forming the nut, the mounting position in the pipe direction with respect to the lock nut main body 10 can be positioned.

By forming several grooves 10b extending in the pipe direction on the peripheral surface of the lock nut body 10, forming ridges 11a extending in the pipe direction on the outer peripheral surface of the lock nut screw portion, and inserting the ridges 11a into the grooves 10b. , The lock nut body and the lock nut screw portion can be positioned in the circumferential direction.
Further, since the ridge 11a protrudes from the peripheral surface of the lock nut screw portion, it serves as a non-slip during operation.
Further, the tip side of the lock nut body 10 has a small inner diameter, and a brim portion 10a having a diameter larger than that of the hose to be connected to the hose connecting pipe portion 4a and a diameter smaller than that of the restraining claw 8a of the claw member 5 is formed. Has been done.

As the material of the lock nut body 10 and the lock nut screw portion 11, a resin capable of ultrasonic welding is preferable. Among them, ABS (acrylonitrile, butadiene, styrene copolymer synthesis) resin is particularly preferable because it is particularly suitable for ultrasonic welding. In the embodiment of the present invention, ABS resin is used.

The lock nut body 10 and the lock nut screw portion 11 may be integrally molded from the beginning, but an undercut treatment of the mold is required.
By forming the lock nut 6 from the lock nut main body 10 and the lock nut screw portion 11, each component can be easily molded, and the lock nut 6 having a complicated shape can be formed.
Any fixing method such as welding or screw fixing may be used as the fixing method between the lock nut body 10 and the lock nut screw portion 11, but from the viewpoint of improving productivity, fixing by ultrasonic welding is particularly preferable. In the embodiment of the present invention, the inner peripheral surface of the lock nut body 10 and the outer peripheral surface of the lock nut screw portion 11 are fixed by ultrasonic welding.

The mounting means of the joint body 4 and the lock nut 6 is not limited to screw connection, and the position can be adjusted in the pipe direction, and the position can be fixed in at least two stages of a shallow fitting state and a deep fitting state. Fitting means may be employed.
The shallow fitting state is from the state in which the female threaded portion 7b of the lock nut 6 and the male threaded portion 7a of the joint body 4 have begun to fit to the state immediately before the restraining claw 8a comes into contact with the reduced diameter opening portion 4c. A state in which the lock nut 6 is tightened at a certain position is shown, and a deep fitting state means that the lock nut 6 is further tightened, the restraining claw 8a abuts on the reduced diameter opening 4c, and the diameter is along the reduced diameter opening 4c. It shows a state in which the hose H is elastically deformed inward in the direction and is strongly adhered to the hose connecting pipe portion 4a by pressing the hose H.
For example, a protrusion is projected from the inner peripheral surface of the lock nut 6, and a vertical groove extending in the pipe direction is carved on the outer peripheral surface of the outer cylinder 4b of the joint body 4, and the shallow position and the deep position of the vertical groove are respectively. By engraving a horizontal groove extending in the circumferential direction and sliding the protrusion in the vertical groove toward the pipe and rotating the lock nut 6 at the position of the horizontal groove, the protrusion enters the horizontal groove and is fixed in the pipe direction. You may be able to do it.

In order to assemble the hose joint 1 according to the embodiment of the present invention, as shown in FIGS. 5A and 5B, the claw member 5 is first inserted into the lock nut body 10, and then the lock nut screw portion 11 is inserted into the lock nut body 10. Attached to and fixed by ultrasonic welding. At this time, the positioning protrusion portion of the claw member stopper 9 is sandwiched between the lock nut screw portion 11 and the lock nut main body 10 and fixed in the pipe direction, but can freely rotate in the circumferential direction. The claw member 5 is oriented so that the restraining claw 8a is arranged on the base end side in the pipe direction of the hose connecting pipe portion 4a and the claw member stopper 9 is arranged on the tip end side in the pipe direction of the hose connecting pipe portion 4a.
At this time, the claw member main body 8 is sandwiched between the brim portion 10a of the lock nut main body 10 on the distal end side in the pipe direction and the positioning protrusion 9a of the claw member stopper 9 on the proximal end side in the pipe direction, thereby being sandwiched between the lock nut 6 and the lock nut 6. On the other hand, it is fixed in the pipe direction.

Next, the lock nut 6 is arranged on the outer peripheral side of the hose connecting pipe portion 4a and the claw member 5. At this time, the female threaded portion 7b of the lock nut 6 may be shallowly fitted to the male threaded portion 7a of the joint body 4, or the lock nut 6 may be simply arranged without fitting.

Next, the hose H is put on the hose connection pipe portion 4a and connected.
From this state, the locknut 6 is rotated to fit the male threaded portion 7a and the female threaded portion 7b to a deeply fitted state (FIG. 5 (b)), and the restraining claw 8a becomes the diameter reduction port of the joint body 4. It comes into contact with the portion 4c, elastically deforms inward in the radial direction along the diameter reduction port portion 4c, and presses the hose H so that it can be strongly adhered to the hose connecting pipe portion 4a.
In this way, the hose can be easily connected to the hose joint 1 simply by fitting the lock nut 6 and the joint body 4.

When the screw connection is loosened from the deep fitting state and the fitting state is shifted to the shallow fitting state (FIG. 5 (a)), the reduced diameter opening 4c is separated from the restraining claw 8a toward the proximal end side, and the restraining claw 8a returns to the original shape. Return. When the hose H is pulled in a state where the pressing of the restraint claw 8a on the hose H is released, the hose H can be removed from the hose connecting pipe portion 4a.
Unlike the conventional hose joint, the restraint claw 8a is formed on the base end side of the claw member 5, and the reduced diameter opening 4c is located on the base end side of the restraint claw 8a. Therefore, when the hose H is pulled. Even if the restraint claw 8a bends toward the tip side due to frictional force, the hose is rather moved away from the reduced diameter opening 4c, and the restraining claw 8a does not press the hose H along the reduced diameter opening 4c. H can be easily removed.

Further, since it is not necessary to remove the lock nut 6 from the joint body 4 in order to remove the hose H, the claw member 5 is damaged or lost when the lock nut 6 is removed, and the claw member 5 is turned upside down when reassembled. It is possible to prevent the risk of reverse assembly.
In the hose joint 1, the lock nut 6 can be removed from the joint body 4 when the inside needs to be cleaned.
Even when the lock nut 6 is removed from the joint body 4, the claw member 5 does not come off from the lock nut 6. Therefore, the claw member 5 is damaged or lost when the lock nut 6 is removed, and the claw member 5 is reassembled when reassembled. The fear can be further prevented.

When you want to reattach the hose H from the shallow mating state, simply insert the hose H from the lock nut 6, cover the hose connection pipe portion 4a to connect, and operate the lock nut 6 to shift to the deep mating state. The hose H can be pressed by the restraint claw 8a to be strongly brought into close contact with the hose connecting pipe portion 4a.

In the embodiment of the present invention, the deep fitting state is preferably a state in which the male screw portion 7a and the female screw portion 7b are tightened to the root as much as possible and the hose H is completely attached. Further, in order to shift to the shallow fitting state, it is preferable to set the dimensions so that the joint body 4 and the lock nut 6 are separated from each other by 3 mm or more in the pipe direction (axial direction) from the deep fitting state. If it is less than 3 mm, it is difficult for the user to visually distinguish between the deep fitting state and the shallow fitting state, and the fitting state may change against the intention of the user. Further, if this dimension exceeds 20 mm, the size of the device becomes large and the amount of movement (operation amount) of the lock nut 6 for shifting to a shallow fitting state becomes large and the operability deteriorates. Therefore, the size should be 20 mm or less. It is preferable, and it is particularly preferable that it is 12 mm or less. In the embodiment of the present invention, it is set to 6 mm.

In the hose joint according to the embodiment of the present invention, if the claw member 5 is fixed to the lock nut 6 in the pipe direction and the lock nut 6 is brought into a shallow fitting state, the restraining claw 8a is surely reduced in diameter. In addition to being separated from the restraint claw 8a, the restraint claw 8a is formed on the proximal end side of the claw member 5, and the reduced diameter portion 4c is located on the proximal end side of the restraint claw 8a. Even if the restraining claw 8a bends toward the tip side due to frictional force, the hose is rather moved away from the reduced diameter opening 4c, and the restraining claw 8a does not press the hose H along the reduced diameter opening 4c. H can be easily removed.

Further, since the restraint claw 8a is formed on the base end side of the claw member 5, when the hose H is pressed by the restraint claw 8a, even if the hose H swells on the tip side from that position, other parts of the claw member 5 are formed. Therefore, the swelling of the hose H can be suppressed. Therefore, it is not necessary to provide the lock nut 6 with a long tubular hose retainer, the total length of the hose joint 1 can be shortened, and the material cost can be reduced.

Further, since the restraint claw 8a is formed on the base end side of the claw member 5, the position where the hose H is pressed by the restraint claw 8a is closer to the base end side than before, so that the hose connection pipe portion 4a is shorter than before. And the material cost can be reduced. Further, by making the hose connecting pipe portion 4a shorter than the conventional one, the contact area between the hose connecting pipe portion 4a and the hose H becomes smaller, so that the frictional force between the hose connecting pipe portion 4a and the hose H can also be reduced. , The hose H can be easily removed.

Further, since the claw member main body 8 is fixed to the lock nut 6 in the pipe direction, the claw member main body 8 moves as compared with the case where the claw member main body 8 is movable in the pipe direction with respect to the lock nut 6. Since the space for the hose joint 1 can be omitted, the total length of the hose joint 1 in the pipe direction can be shortened, and the material cost can be reduced.

In the embodiment of the present invention, the claw member 5 is fixed to the lock nut 6 by sandwiching the claw member stopper 9 between the lock nut main body 10 and the lock nut screw portion 11, but instead of this, the lock nut 10 A male screw portion that can be screwed to the female screw portion 7b may be formed on the outer periphery of the claw member stopper 9, and the claw member 5 may be fixed to the lock nut 6 by screw coupling.
