JP3041239U - Water Faucet with Saddle for Flexible Pipe - Google Patents

Abstract

(57) [Abstract] [Purpose] When the main pipe connected to the water faucet is a flexible pipe such as polyethylene pipe, the flexible pipe is crushed from the top and bottom by tightening with the saddle band and deformed to protrude from the saddle band. , It may cause cracks or water leakage. Therefore, a yoke body that can be opened and closed is attached to the saddle band, and the flexible tube is wrapped by the yoke body to prevent the flexible tube from protruding from the saddle band, but the outer surface of the flexible tube slips. Since it is an easy smooth surface, the grasped flexible tube will not be firmly fixed by rotating or shifting in the yoke body, and water leakage due to deviation of the water diversion port becomes a further problem. , Aim to solve this. [Structure] A protrusion 51 for gripping the outer surface of the flexible tube A inside,
A pair of auxiliary yokes 5a and 5b provided with 51 are arranged so as to face each other, and the auxiliary yokes are configured so as to be openable and closable with the mounting position on the lower saddle 4 as a fulcrum. A lower saddle in which a yoke body configured to contact the inside of the upper saddle 3 at the time of wearing is attached,
A saddle band consisting of an upper saddle with an attachment for the faucet was attached to the faucet.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a water faucet with a saddle for a flexible pipe, which is used when a water main pipe or a distribution pipe made of a flexible pipe such as a polyethylene pipe is branched into a branch pipe.

[0002]

[Prior art]

 Regarding the water faucet with a saddle for a flexible tube, an invention by the applicant of the present application as Japanese Patent Publication No. 60-44550 is patented and exists as a prior art. Was not applied.

[0003]

[Problems to be solved by the device]

 When branching from a main pipe such as a water distribution pipe to a branch pipe, connect the water dip to the main pipe side with a saddle band, but if the main pipe is made of cast iron and is not easily deformed, start from the top and bottom of the main pipe. It can be connected by sandwiching it in two halves and tightening it with bolts, but when the main pipe is a flexible pipe such as polyethylene pipe, the flexible pipe is crushed from the top and bottom by deformation and protrudes from the saddle band. , Causing cracks and water leakage.

Therefore, in the above invention, a yoke body that can be opened and closed is attached to the saddle band, and the flexible tube is wrapped with the yoke body to prevent the flexible tube from protruding from the saddle band. However, since the outer surface of the flexible tube is a smooth surface that is slippery, the grasped flexible tube will not rotate or move within the yoke body and will not be firmly fixed, and the Water leakage due to misalignment is a further problem.

In addition, there is also a problem in that when the water diversion port is attached to the main pipe side and then the water diversion port is punched from the upper portion, if the flexible pipe is not firmly fixed, proper perforation cannot be performed.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, a water faucet with a saddle for a flexible tube according to the present invention is provided with a pair of auxiliary yokes facing each other, and a pair of auxiliary yokes provided with a protrusion for gripping the outer surface of the flexible tube. Are configured to be openable and closable with the mounting position to the lower saddle as a fulcrum, and the upper saddles of the auxiliary yokes contact the inside of the upper saddle when tightened. And a saddle band consisting of an upper saddle with an attachment part for the faucet is attached to the faucet.

Further, the protrusion for holding the outer surface of the flexible tube is formed by bending the required outer edge portion of the auxiliary yoke to the inner side and making it stand up, and by bending the edge of the auxiliary yoke, the tip of the bent end is bent. The tip of the flexible tube is positively pushed into the outer surface of the flexible tube to fix the flexible tube to the inner surface of the auxiliary yoke, and if necessary, the protrusion is provided by a ridge that bends the inner surface of the auxiliary yoke. The flexible tube is fixedly held by the entire inner surface of the auxiliary yoke.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 is a main body of the water faucet, which has a branch valve built in and a lower end portion which is a mounting portion 2 to a saddle band which is screwed into a main body mounting screw hole 31 provided in an upper saddle 3. At the lower part of the attachment screw hole 31 of the upper saddle 3, a seal member 32 is installed which is located between the outer surface of the flexible pipe A which is the main pipe and keeps the lower periphery of the attachment screw hole 31 watertight. .

A lower saddle 4 has a pair of arc-shaped auxiliary yokes 5a and 5b, which are provided with protrusions 51, 51, ... It is arranged so that it can be opened and closed with the mounting shaft 53 as a fulcrum.

.. formed on the inner surface of the auxiliary yokes in a grid pattern as shown in FIG. 5 on the auxiliary yokes 5a, 5b. Alternatively, as shown in FIGS. 6 and 7, the protrusions 52, 52, ... Are formed vertically or horizontally side by side to correspond to the shape of the outer surface of the flexible tube A. The point-like projections may be scattered on the contact surface.

That is, when the upper saddle 3 is not provided, the lower ends of the auxiliary yokes 5a and 5b rotate around the mounting shaft 53 as a fulcrum, apart from the inner surface of the lower saddle, and the upper ends of the auxiliary yokes 5a and 5b expand to the open state. The flexible tube A is opened so as to be wider than the inner diameter so that the flexible tube A can be easily fitted.

Brackets 6a and 6b, which are pivotally mounted, are provided at both ends of the auxiliary yokes 5a and 5b, and the auxiliary yokes 5a and 5b are pivotally supported on the inner surface of the lower saddle 4 by a mounting shaft 53.

Therefore, when the flexible pipe A connecting the lower saddle 4 is brought into contact with the lower side of the flexible pipe A, the upper ends of the auxiliary yokes 5a and 5b are pushed open by the outer peripheral surface of the flexible pipe A, and the flexible pipe A is formed into a yoke body. It is received in 5 and fitted into the lower saddle 4.

When the flexible tube A is fitted into the lower saddle 4, the lower ends of the auxiliary yokes 5a and 5b are pushed down and the upper ends are closed, and the inner surfaces of the auxiliary yokes 5a and 5b provided with the projections 51, 51 ... Is brought into close contact with the outer peripheral surface of the flexible tube A.

After the flexible tube A is fitted into the lower saddle 4, the upper saddle 3 is faced and fitted into the flexible tube A, and the tightening bolts 7 are inserted into the bolt insertion holes 8 provided in the upper and lower saddles, respectively. When tightened, the saddle band is attached with the flexible tube A being clamped.

When the upper and lower saddles 3 and 4 are tightened, a gap remains between the flange portions 33 and 41 through which the bolt 7 is inserted, but the auxiliary yokes 5a and 5b close the gap and the flexible tube A is deformed. The upper and lower edges of each auxiliary yoke are in contact with the inside of the upper saddle so as to prevent them from protruding and the upper and lower saddles 3 and 4 are not dislocated and the flexible tube wrapped in the yoke body. It properly holds A from the outside of the yoke body.

After the flexible tube A is attached by the saddle band, the attachment part 2 of the water faucet body 1 is screwed and attached to the body mounting screw hole 31 provided in the upper saddle 3, and the body of the water faucet body 1 is attached. By piercing the outer surface of the flexible tube A that abuts the lower part of the mounting screw hole 31 from the upper part by the piercing machine, the water dip 1 from the flexible tube A of the main pipe to the diversion branch pipe is connected.

Since the present invention is configured as described above, the workability in attaching to the main pipe is extremely good, and after the attachment, the flexible pipe as the main pipe is firmly fixed.
