FIG. 4 is an external perspective view of a gas station using the hose processing mechanism of the oil supply apparatus according to the embodiment of the present invention.

In these figures, a refueling area 2 is provided on the front of a vertically long island 1 provided on the site of a gas station, and a measuring unit 4 stands upright on the island 1. A canopy 3 is provided above the refueling area 2, and a refueling hose processing case 21 constituting a hose processing mechanism 20 is suspended from the canopy 3.

The weighing unit 4 is formed in a narrow case shape as a whole, and its upper side is formed so as to project horizontally in the direction along the vertically long island 1. An apparatus 6 and a plurality of nozzle mounts 7 (for example, three locations on each side, a total of six locations) are provided. A refueling amount indicator 8 is provided above the measuring unit 4.

The oil supply hose processing case 21 is formed in an elongated box having a relatively narrow width, and is suspended from the canopy 3 so that its longitudinal direction is perpendicular to the vertically long island 1. At the end of the refueling hose processing case 21 on the island 1 far from the measuring unit 4, the underground is connected to the underground via a canopy 3 from the upper part of the refueling hose processing case 21 via a flowmeter (not shown), a refueling pump, or the like. An oil supply pipe 16 connected to an oil supply system communicating with the tank (for example, three kinds of oil, two each of three kinds of oil such as high octane gasoline, regular gasoline, light oil, etc., a total of six pipes) is provided. I have. These oil supply pipes 16
Is bent slightly toward the center (the weighing unit 4 side) in the lower part of the refueling hose processing case 21, and one end of the refueling hose 11 is connected via a swivel joint 15 fixed to each end. Have been. These refueling hoses 11 are composed of a short hose 11a and a long hose 11b, both of which are connected via an intermediate swivel joint 13 and a safety pipe joint 12, and a refueling nozzle 10 is provided at an end of the long hose 11b, respectively. It is connected. These refueling hoses 11 have long holes 17 formed in the lower part of the refueling hose processing case 21 along the longitudinal direction orthogonal to the island 1 (for example, six places necessary for suspending six refueling hoses 11). It is derived from and suspended. Each refueling nozzle 10 can be hung on a corresponding nozzle hanger 7 provided in the measuring unit 4.

On the upper side of the center of the hose processing case 21 (position above the weighing unit 4 on the island 1), corresponding retractors 23 are arranged. The leading end of the drawn wire 24 is connected to the corresponding intermediate swivel joint 13. That is, the wire 24 of the retractor 23 pulls the upper end of the oil supply hose 11 upward at the intermediate swivel joint 13 to urge it.
The lifting force of the retractor 23 is set to a force sufficient to support the weight of the refueling hose 11, and the safety fitting 12 separates when an unexpected force is applied to the refueling nozzle 10.

The operation of the hose processing mechanism of the oil supply device having the above configuration will be described. When the fuel is not initially supplied, as shown in a position A of FIG. 1, the intermediate swivel joint 13 is pulled up by the wire 24 of the retractor 23 to the position of the retractor 23 immediately above the measuring unit 3. Is located in a vertically suspended state substantially at the center of the hose processing case 21, and the refueling nozzle 1

Next, when lubricating the fuel supply port of the vehicle near the metering unit 4, when the fuel supply hose 11 is pulled by hand, the wire 24 connected to the intermediate swivel joint 13 resists the urging force of the retractor 23. The short hose 11a is slightly bent so that the oil supply hose 11 comes to the position B in FIG. 1 and the oil supply nozzle 10 can be brought close to the oil supply port to supply oil. When refueling is completed and the refueling nozzle 10 is hung on the nozzle hook 7, the wire 24 is retracted by the retractor 23, and the refueling hose 11 returns to the original position. When refueling the fuel supply port of the automobile farther from the metering unit 4, similarly, when the fuel supply hose 11 is pulled by hand, the wire 24 connected to the intermediate swivel joint 13 is connected.
Is pulled out, the refueling hose 11 moves to the position of C in FIG. 1, and the refueling nozzle 10 can be brought closer to the refueling port. At this time, the short hose 11a bends in a substantially inverted U-shape to facilitate feeding of the oil supply hose 11. When refueling is completed and the refueling nozzle 10 is returned to the nozzle hook 7, the intermediate swivel joint 13 is pulled up by the wire 24 of the retractor 23 and returns to the original position. When the short hose 11a and the long hose 11b are extended between the fixed swivel joint 15 and the refueling nozzle 10 as shown in a position D in FIG. 1, the refueling nozzle 10 can be moved to a farther position. If an excessive force is applied to the oil supply hose 11 during these operations, the safety pipe joint 12 is separated to prevent an unexpected force from being applied to the oil supply hose 11 and the hose processing case 21 and stop the oil outflow. I do.

The hose treatment mechanism of the oil supply device of the present invention does not require complicated parts such as a movable trolley and rails in the hose treatment case 21, so that the weight and cost can be reduced and the hose treatment can be easily performed. Become. Since the short hose 11a and the long hose 11b are connected via the intermediate swivel joint 13 and the safety pipe joint 12, breakage of the oil supply hose 11 and the hose processing case 21 and outflow of oil can be prevented.

In this embodiment, the hose processing case 2
Although the example in which 1 is hung from the canopy 3 has been described, it is also possible to erect a support and attach it to the upper part thereof. The oil supply pipe 16 and the oil supply hose 11 are connected to the swivel joint 15.
And the intermediate swivel joint 13 and the safety pipe joint 12 are interposed in the middle of the oil supply hose 11, but are connected by at least one or more swivel joints, and the safety pipe joint is provided in the middle of the oil supply hose 11. Is also good.
