  The present invention relates to a hose joint that is mainly used for gardening, agriculture, and cleaning at home and the like, and connects a hose and another device to allow fluid to pass.

A hose coupling is connected to a hose at one end and another device such as another hose, a water tap, a watering nozzle, a hose reel, etc., or other device (hereinafter simply referred to as “other device”). A hollow device that allows fluid to pass between the hose and other devices.
Devices used for watering, such as these watering nozzles and hose reels, are hereinafter referred to as “watering devices”.
Moreover, the side which connects a hose in a hose coupling is called a front end side, and the reverse direction is called a base end side.

  As shown in FIG. 6, Patent Document 1 discloses a joint body 24 having a tubular hose connection 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, and a hose connection. A claw member 25 provided on the outer peripheral side of the pipe portion 24a and provided with a restraining claw 28a capable of pressing the hose H in the radial direction on the inner periphery, and arranged on the outer peripheral side of the hose connection pipe portion 24a and the claw member 25 The base end side is externally fitted to the joint main body 24 so that the position can be adjusted in a shallow and shallow position in the pipe direction. A hose coupling 21 having a lock nut 26 is described.

In the hose joint 21, the claw member 25 has a claw member stopper 29 fixed to the lock nut 26 in the pipe direction and a restraining claw 28 a and is movable in the pipe direction with respect to the claw member stopper 29 and detached. The claw member main body 28 is attached so as not to be removed.
Further, the restraining claw 28 a is formed on the distal end side in the tube direction of the claw member 25, that is, on the hose attachment side in the hose joint 21.

  In order to connect the hose H to the hose joint 21 of Patent Document 1, as shown in FIG. 6 (b), the lock nut 26 is disposed on the outer peripheral side of the joint body 24, and then the hose H is connected to the hose connection 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 suppression claw 28a from the front end side, and the suppression claw 28a extends along the reduced diameter opening 30a. As a result, the hose H can be strongly adhered to the hose connecting pipe portion 24a by elastic deformation inward in the radial direction.

When removing the hose H from the state where it is connected to the hose coupling 21, as shown in FIG. 6 (a), by rotating the lock nut 26 into a shallow fitting state, the restraining claw 28a and the reduced diameter opening 30a A gap is formed between them, and the hose H is pulled and removed from the hose connection pipe portion 24a.

The hose H is pressed inward in the radial direction along the inclination of the diameter-reduced opening 30a, and it may be difficult to remove the hose H.

  Further, when the hose H is pressed against the hose connection pipe portion 24a by the restraining claw 28a, the hose H may swell radially outward at the tip side from the position. It was preferable to provide a long cylindrical hose restrainer 30b on the tip side of the 26 diameter-reduced opening 30a.

  This invention is made | formed in order to solve the said problem, and makes it a subject to provide the hose coupling which can attach or detach a hose easily.

In the present invention, means for solving the above problems are as follows.
1st invention is a hose coupling which connects a hose and another apparatus and allows fluid to pass through, a joint main part which has a tubular hose connection pipe part which can be inscribed in the above-mentioned hose in the tip side, and the above-mentioned hose connection pipe part Arranged on the outer peripheral side of the hose, and provided on the inner periphery with a claw member provided with a detent claw capable of pressing the hose in the radial direction, on the outer peripheral tip side of the hose connecting pipe part and the claw member, A lock nut that fits in the pipe direction so that the position can be adjusted shallowly, and the claw member is fixed to the lock nut in the pipe direction, and the detent claw is formed on the proximal end side of the claw member, The joint body is provided with a diameter-reduced opening that is larger in diameter than the hose and smaller in diameter than the claw member. In a shallow fitting state of the joint body and the lock nut, the diameter-reduced opening is based on the restraining claw. Located on the end side The deep fitting state between the main body and the lock nut, characterized in that it is possible the suppression pawl presses the hose along the reduced 径口 unit.

  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 brought into a shallow fitting state, the restraining claw is surely separated from the reduced diameter opening. 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 smaller than that of the claw member, and the joint body and the lock nut are shallow. In the fitted state, since the diameter-reducing opening portion is located on the proximal end side with respect to the inhibition claw, even if the inhibition claw is bent toward the distal end side due to frictional force when the hose is pulled, the diameter-reducing opening is reduced. Rather, the hose can be easily removed. In addition, in the deep fitting state between the joint body and the lock nut, the restraining claw can press the hose along the reduced diameter opening portion, thereby operating the fitting state between the joint body and the lock nut. The hose can be easily pressed simply by doing.

  According to the second invention, the restraining claw is elastically deformed in the radial direction by holding the restraining claw rotatably in the circumferential direction in a shallow fitting state between the joint body and the lock nut. The escape allowance is facilitated, and the hose can be effectively pressed or removed with a small amount of operation.

It is sectional drawing of the hose coupling, (a) has shown the shallow fitting state, (b) has shown the deep fitting state. It is sectional drawing of the conventional hose coupling, (a) has shown the shallow fitting state, (b) has shown the deep fitting state.

Hereinafter, the hose coupling according to the present invention will be described.
The hose joint 1 is an instrument that connects a hose and another device to allow fluid to pass through, and connects the hose and another hose as shown in FIG. 1 (a), as shown in FIG. 1 (b). 1 to connect the hose and the faucet, as shown in FIG. 1 (c), attached to the watering nozzle 2 and connected to the hose, as shown in FIG. 1 (d), the hose H and watering of the hose reel 3 Various things, such as what connects with the nozzle 2, are included.

Below, the hose coupling 1 which connects a hose and a faucet like FIG.1 (b) is demonstrated as embodiment of this invention.
As shown in FIG. 2, the hose joint 1 includes 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 that can connect a hose H (see FIG. 5B) to the tip and connect the other end to another device (not shown). Thus, fluid can be passed between the hose H and another device.
Hereinafter, the side to which the hose H is attached in the hose joint 1 is referred to as a distal end side, and the opposite direction is referred to as a proximal end side.

As shown in FIGS. 2 and 5, an outer diameter tubular hose connection pipe portion 4 a that can be inscribed in the hose H is formed at the tip of the joint body 1. You may reinforce suitably by providing a rib in the inner peripheral surface of the hose connection pipe part 4a.
An outer cylinder 4b is provided around the hose connection pipe 4a. On the outer peripheral surface of the outer cylinder 4b, a male screw portion 7a for screw coupling to the lock nut 6 is formed.

  In addition, a reduced diameter opening portion 4c is formed at the distal end of the outer cylinder 4b so that the inner diameter gradually decreases toward the proximal end side. The distal end of the reduced diameter opening portion 4c has a larger diameter than a suppression claw 8a of the claw member 5 described later, and the proximal end of the reduced diameter opening portion 4c is formed to have a smaller diameter than the suppression 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 plan view. A restraining claw 8a is formed on the upper end portion of the hose joint 1 that is directed toward the proximal end side.
The restraining claw 8 a is formed by projecting two upper and lower ridges radially inward from the inner peripheral surface of the claw member main body 8. Twelve suppression claws 8a are formed at equal intervals on the circumference.
By adopting 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 protrusions of the restraining claw 8a that holds the hose may be one or more, but it is not limited. However, the molding of the restraining claw 8a requires under-cutting on the mold, so it is necessary to remove it by force. If it exceeds 1, there is a possibility that it cannot be forcibly removed for molding. In the embodiment of the present invention, two protrusions are provided.
Further, if the length of protrusion of the detent 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 restraining claw 8a needs to be increased accordingly, and the apparatus becomes larger, so 1.8 mm or less is preferable, and 1.2 mm or less is particularly preferable. In the example, it was 0.5 mm.
If the length of the claw member main body 8 in the tube direction (axial direction) is less than 3 mm, it is difficult to elastically deform in the radial direction, and when the hose H is pressed, the pressing force with the lock nut 6 is required. Is preferably 6 mm or more. In addition, if it exceeds 20 mm, the apparatus becomes large, and the moving amount (operating amount) of the lock nut 6 necessary for providing a clearance when releasing the pressing of the hose H becomes large and the operability deteriorates. The following is preferable, and especially 15 mm or less is preferable. In the example, it was 12.4 mm.
As the material of the claw member main body 8, a resin having elasticity is suitable, and a PP (polypropylene) resin is particularly preferred because it has excellent hinge characteristics. In the embodiment of the present invention, PP resin is employed.

As shown in FIG. 4, the claw member stopper 9 is a ring-shaped part inscribed in the claw member main body 8, and 12 positioning projections 9a projecting radially outward are provided at equal intervals on the circumference. ing.
The positioning protrusion 9a passes through 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, etc. can be used for the material of the nail | claw member stopper 9, and since it is cheap, resin is preferable. Among them, PP resin is particularly preferable because it is particularly inexpensive. In the embodiment of the present invention, PP resin is employed.

In order to assemble the claw member 5, the positioning protrusion 9 a of the claw member stopper 9 is inserted into a groove formed between the restraining claw 8 a of the claw member main body 8, and the claw member stopper 9 is inserted into the claw member main body 8. Make contact. At this time, the restraining claw 8a and the positioning protrusion 9a are alternately arranged in the circumferential direction of the claw member 5.
In the state where the claw member 5 is assembled, the restraining claw 8a is formed on substantially the entire circumference. However, by providing a gap between the restraining claw 8a, the claw member main body 8 is easily elastically deformed in the radial direction, and each restraint is formed. The claw 8a is easy to swing in the radial direction.
The number of restraining claws 8a arranged in the circumferential direction may be one or more and is not limited. In the embodiment of the present invention, the number is 12.
In the case where a plurality of restraining claws 8a are provided, it is preferable to arrange them at equal angular positions on the circumference in order to evenly tighten the entire circumference of the hose.
The claw member 5 is disposed on the outer peripheral side of the hose connection pipe portion 4 a in the hose joint 1.

As shown in FIGS. 2 and 5, the lock nut 6 includes a cylindrical lock nut main body 10 that can cover the outer peripheral side of the hose connecting pipe portion 4 a and the claw member 5, and a male screw portion 7 a of the joint main body 4. A lock nut screw portion 11 having an inner peripheral surface formed with a female screw portion 7b to be screwed is joined 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 protrudes radially outward so that the base end portion cannot be inserted into the lock nut main body 10. By forming in this, the attachment position of the pipe direction with respect to the lock nut main body 10 can be positioned.

By forming several grooves 10b extending in the tube direction on the peripheral surface of the lock nut main body 10, and forming a protrusion 11a extending in the tube direction on the outer peripheral surface of the lock nut screw portion, the protrusion 11a is inserted into the groove 10b. The lock nut body and the lock nut threaded portion can be positioned in the circumferential direction.
Moreover, since the protrusion 11a protrudes from the surrounding surface of a lock nut screw part, it becomes a slip prevention at the time of operation.
Further, the inner diameter of the distal end side of the lock nut main body 10 is small, and a flange portion 10a having a diameter larger than that of the hose to be connected to the hose connection pipe portion 4a and smaller than that of the claw member 8a of the claw member 5 is formed. Has been.

  The material of the lock nut main body 10 and the lock nut screw portion 11 is preferably a resin capable of ultrasonic welding. 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 employed.

Although the lock nut main body 10 and the lock nut screw portion 11 may be integrally formed from the beginning, an undercut process for 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 part can be easily molded, and the lock nut 6 having a complicated shape can be formed.
The fixing method between the lock nut body 10 and the lock nut screw portion 11 may be any fixing method such as welding or screw fixing, 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 attachment means between the joint body 4 and the lock nut 6 is not limited to the screw connection, but can be adjusted in the pipe direction, and can be positioned at least in two stages of a shallow fitting state and a deep fitting state. You may employ | adopt a fitting means.
The shallow fitting state refers to a state from a state where the female screw portion 7b of the lock nut 6 and the male screw portion 7a of the joint body 4 start to be fitted to a state immediately before the restraining claw 8a is in contact with the reduced diameter opening portion 4c. The state where the lock nut 6 is tightened at a certain position is shown. The deep fitting state means that the lock nut 6 is further tightened and the detent claw 8a comes into contact with the reduced diameter opening 4c, and the diameter along the reduced diameter opening 4c. The state which elastically deformed inside the direction, pressed the hose H, and was made to closely_contact | adhere to the hose connection pipe part 4a is shown.
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 formed on the outer peripheral surface of the outer cylinder 4 b of the joint body 4, and each of a shallow position and a deep position of the vertical groove is provided. A horizontal groove extending in the circumferential direction is engraved, and the protrusion is slid in the pipe direction in the vertical groove, and by rotating the lock nut 6 at the position of the horizontal groove, the protrusion enters the horizontal groove and stops 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. 5 (a) and 5 (b), the claw member 5 is first put in the lock nut main body 10, and then the lock nut screw portion 11 is inserted into the lock nut main body 10 as shown in FIGS. And fixed by ultrasonic welding. At this time, the positioning protruding 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 disposed on the proximal end side in the tube direction of the hose connection tube portion 4a and the claw member stopper 9 is disposed on the distal end side in the tube direction of the hose connection tube portion 4a.
At this time, the claw member main body 8 is sandwiched between the flange portion 10a of the lock nut main body 10 on the distal end side in the tube direction and the positioning projecting portion 9a of the claw member stopper 9 on the proximal end side in the tube direction. On the other hand, it is fixed in the tube direction.

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

Next, the hose H is connected to the hose connecting pipe portion 4a.
When the lock nut 6 is rotated from this state and the male screw portion 7a and the female screw portion 7b are fitted to a deep fitting state (FIG. 5 (b)), the restraining claw 8a becomes the reduced diameter opening of the joint body 4. By abutting on the portion 4c, elastically deforming radially inward along the diameter-reducing port portion 4c, and pressing the hose H, the hose connecting pipe portion 4a can be strongly adhered.
Thus, the hose can be easily connected to the hose joint 1 simply by fitting the lock nut 6 and the joint body 4 together.

When the screw connection is loosened from the deep fitting state to shift to the shallow fitting state (FIG. 5A), the reduced diameter opening 4c moves away from the restraining claw 8a to the proximal end side, and the restraining claw 8a is restored to its original shape. Return. If the hose H is pulled in a state where the pressing of the restraining claw 8a to the hose H is released, the hose H can be removed from the hose connection pipe portion 4a.
Unlike the conventional hose joint, the restraining claw 8a is formed on the proximal end side of the claw member 5, and the reduced diameter opening portion 4c is located on the proximal end side from the restraining claw 8a. Therefore, when the hose H is pulled. Even if the restraining claw 8a bends to the distal end side due to the frictional force, the restraining claw 8a will rather move away from the reduced diameter opening 4c, and the restraining claw 8a will 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 direction of the claw member 5 is reversed when reassembling. This can 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, so that the claw member 5 is damaged or lost when the lock nut 6 is removed, and the reverse assembly when reassembling is performed. The fear can be further prevented.

  To reattach the hose H from the shallow fitting state, simply insert the hose H from the lock nut 6, connect it over the hose connection pipe 4 a, and operate the lock nut 6 to shift to the deep fitting state. The hose H can be pressed by the restraining claw 8a so that the hose connecting pipe portion 4a can be tightly adhered.

  In addition, in this embodiment of this invention, it is preferable that the deep fitting state is a state in which the male screw portion 7a and the female screw portion 7b are generally tightened to the root as much as possible and the mounting of the hose H is completed. 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 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 user's will. Further, if this dimension exceeds 20 mm, the apparatus becomes larger and the moving amount (operating amount) of the lock nut 6 for shifting to a shallow fitting state is increased and the operability is deteriorated. Particularly, it is particularly preferable that the thickness is 12 mm or less. In the embodiment of the present invention, it is 6 mm.

  In the hose joint according to the embodiment of the present invention, if the claw member 5 is fixed in the pipe direction with respect to the lock nut 6, the detent claw 8 a is surely connected to the reduced diameter port portion when the lock nut 6 is in a shallow fitting state. When the hose H is pulled, the restraining claw 8a is formed on the proximal end side of the claw member 5 and the reduced diameter opening portion 4c is located on the proximal end side of the restraining claw 8a. Even if the restraining claw 8a bends to the distal end side due to the frictional force, the restraining claw 8a will rather move away from the reduced diameter opening 4c, and the restraining claw 8a will not press the hose H along the reduced diameter opening 4c. H can be easily removed.

  Further, since the restraining claw 8a is formed on the proximal end side of the claw member 5, when the hose H is pressed by the restraining claw 8a, even if the hose H swells at the tip side from the position, Therefore, the hose H can be prevented from swelling. Therefore, there is no need to provide a long cylindrical hose restraint on the lock nut 6, the overall length of the hose joint 1 can be shortened, and the material cost can be reduced.

  Furthermore, since the restraining claw 8a is formed on the proximal end side of the claw member 5, the position at which the hose H is pressed by the restraining claw 8a is closer to the proximal end than the conventional one, so that the hose connecting pipe portion 4a is shorter than the conventional one. The material cost can be reduced. In addition, since the contact area between the hose connection pipe portion 4a and the hose H is reduced by shortening the hose connection pipe portion 4a as compared with the prior art, the frictional force between the hose connection pipe portion 4a and the hose H can also be reduced. The hose H can be easily removed.

  Further, by fixing the claw member main body 8 in the pipe direction with respect to the lock nut 6, the claw member main body 8 moves compared to 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 doing so 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. A male screw portion that can be screw-coupled 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 connection.
