Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hose made of synthetic resin or the like provided with a rotatable joint. For details, install a rotatable joint at a key point or in the middle of a hose that temporarily disperses or transports water etc. while extending or hoisting and bending the hose each time it is used. The present invention relates to a device that prevents, reduces or eliminates the twisting that occurs in the hose, and prevents or prevents the hose from being blocked due to bending caused by the twist.

[0002]

[Prior Art]

 When water is sprayed or sent by a conventional hose, the hose often bends in an α-shape due to the twist generated in the hose, and the hose is often blocked. In particular, when the hose is flexible and long, or when it is rolled and stored in a ring shape when not in use, it is bent and blocked at a high frequency. Therefore, it had to be corrected each time, and it was not convenient to use.

[0003]

[Problems to be solved by the device]

 Since such blockage of the conventional hose is caused by the fining generated in the hose, it is necessary to prevent the honing from occurring in the hose or eliminate the fining generated in the hose.

[0004]

[Means for Solving the Problems]

 In order to deal with this, the hose body is required at a certain point (for example, near the connection with a faucet that is fixed when the hose is stretched, or near the outlet / spray port) or at regular intervals or at arbitrary intervals. A universal joint (B) will be installed in the middle to prevent, reduce or eliminate the twisting that occurs in the hose, which is the cause of bending and blockage.

[0005]

[Action]

 In the hose with a universal joint according to claim 1 (Fig. 1), by attaching the universal joint (B) to the hose, the hose main bodies (A) before and after the universal joint are individually and independently attached via the universal joint. It becomes possible to freely rotate (at least lateral rotation), and one or both of the hose before and after the rotary joint rotates according to the force of the twist generated in the hose by this = the force of lateral rotation. Hinelli is prevented, reduced or eliminated.

In the universal joint (= structure having an outer cylinder and an inner cylinder) provided in the hose of claim 1, the inner cylinder inserted into the outer cylinder slides (rotates) in the outer cylinder. Since the hose connected to the outer cylinder and the hose connected to the inner cylinder rotate through the sliding rotary part in response to the force of the fining generated in the hose, the hose connected to the hose is rotated. Hinelli is prevented, reduced or eliminated.

Of the universal joints according to claim 1, the universal joint (FIG. 2) having a structure in which the outer cylinder (1) and the inner cylinder (2) have a cylindrical shape can rotate only in a structure.

Further, among the universal joints according to claim 1, the universal joint having a structure in which the outer cylinder and the inner cylinder have a spherical shape or at least the inner cylinder has a spherical shape or a hemispherical shape is In addition, a certain amount of vertical rotation (rotation about an axis perpendicular to the extension direction of the hose = swinging / tilting in the extension direction of the hose; hereinafter the same) is also possible.

The universal joint according to claim 2 having a structure without the inner cylinder (see the example of FIG. 3) is inserted and connected to the mounting portion (7) of the hose side withdrawal stop in the outer cylinder. Since the hose side withdrawal stop (6) of the hose slides (rotates) in the mounting part of the hose side withdrawal stop, the hose before and after the hose connected to the outer cylinder (1) is twisted on the hose. The rotation of the hose through the sliding rotary part in response to the force of the hose prevents, reduces or eliminates the twist of the hose.

In the rotary joint of claim 2, the space for the hose side withdrawal stop mounting portion provided in the outer cylinder is U-shaped, V-shaped, W-shaped, or the like. For the hose connected to the hose, the hose on the hose side will be shaped to match the shape of this groove. And the universal joint of this structure can only rotate laterally.

Further, among the rotary joints according to claim 2, the hose side withdrawal stop provided in the outer cylinder has a spherical mounting space, and the hose connected to this has a hose side withdrawal stop shape. As long as it fits the diameter of the spherical space of the mounting portion for the hose side withdrawal stop, not only the spherical shape but also the hemispherical shape or the disk shape may be used. The universal joint having this structure is capable of not only horizontal rotation but also vertical rotation to some extent.

[0012] The condense leak-proof packing prevents the condensate from leaking out of the hose.

In the case of a universal joint that can only laterally rotate as in the case of paragraphs 0007 and 0010, the mounting angle of one of the hose connecting pipes provided in the outer cylinder or the inner cylinder is set to that of the cylinder. Slightly offset from the extension direction angle, or one of the hose connecting pipes shall be slightly bent (in the case of paragraph 0007), or the mounting angle (groove) of the hose side withdrawal stop provided in the outer cylinder. If it is slightly displaced from the transverse angle of the outer cylinder (in the case of paragraph 0010), it is easy for the hose's twisting force to be applied to the sliding rotating part, and smoother rotation should be obtained. Is.

The angling and bending of the hose connecting pipe have the usefulness of making the rod-like shape of the rotatable joint part into a dogleg shape when the hose is wound around the hose roller.
