Description

[Detailed description of the invention] (a) Industrial application field The present application relates to a refueling device that is installed at a refueling station and supplies oil such as gasoline to automobiles.

(b) Prior art and its problems While automobiles have gradually become larger in recent years, the length of the refueling hose in the refueling device is regulated by law, and there is a limit to how long it can be made.

Therefore, a type of lubrication device in which the base of the hose moves horizontally, such as the one seen in 1982-1000, began to be used. To make refueling work more efficient, the distance the hose must travel is long, but
If it is too long, there is a risk that a car entering or exiting the hose may catch the dripping part of the hose when it is not refueling. Therefore, a method of using a spring as a means of pulling back the hose may be considered, but in this case, unless the spring is set sufficiently long compared to the distance to be pulled back, the change in the pulling back force will be large compared to the distance the hose is displaced. This makes it difficult to use.

(c) Structure and operation for solving the problem This application is proposed in view of the above problem, and relates to a structure that urges the hose to return toward the center of the rail when the hose is near the end of the rail. The structure consists of forming a horizontal straight elongated hole in the casing, which is installed at a predetermined height using a support member installed on an island on a dirt floor, and then laying a rail along this elongated hole. , on the other hand, in a device in which a downstream pipe line of a pump and a flow meter is led out from the elongated hole and is driven by a carrier that moves along the rail, both ends of the rail can be displaced only a certain distance along the rail. A regulating piece for restricting the movement of the carrier is provided, a spring is connected between the two regulating pieces to bias the distance between the two regulating pieces in a direction that reduces the distance between the two regulating pieces, and the carrier is arranged between the two regulating pieces. Even if the hose is pulled and the carrier is moved to the maximum extent, when refueling is completed and the pulling force is released, the hose will be pulled back toward the center of the rail by the biasing force of the spring.

(d) Embodiment 1 is a fuel supply system installed on an island I raised on a dirt floor G. At the bottom of the system is a lower housing 2 in which a pump flow meter (not shown) and a display are housed, and at the upper part there is a pump flow meter (not shown), which will be described later. An upper housing 3 is disposed in which a hose moving means for moving the hose is housed.

4 is housed within the cover 5 of the upper housing 3 and is installed horizontally with a rail having a hollow rectangular cross section.

C is a carrier, which consists of two plates P ₁ which sandwich a rail 4 and are connected by four stud bolts S,
P ₂ and four wheels H, each rotating around a bolt S and having a recess 6 that engages with the rail 4;
The carrier C is moved by the wheels H rolling on the upper and lower surfaces of the rail 4.

7 is a plate whose flange 8 is L-shaped.
This is a rotary pipe joint fixed to plate _P1 in a manner that passes through hole 9 of _P1 , and L-shaped pipe joints 10 and 11 are rotatably connected to joint 7 at both ends of joint 7, respectively. .

Reference numerals 12 and 13 denote cylindrical regulating pieces, which are arranged in elongated holes 14 and 15 formed at both ends of the rail 4, respectively, and both ends thereof protrude from the rail 4, and the plates P ₁ and P ₂ of the carrier C come into contact with each other. A certain length is ensured.

Reference numeral 16 denotes a single spring, which is disposed in the hollow part 4' of the rail 4, and its both ends are connected to the regulating pieces 12 and 16, respectively.
13, and normally urges the regulating pieces 12 and 13 toward each other.

17 and 18 are recesses formed in both plates P ₁ and P ₂ respectively, and in which the regulating pieces 12 and 13 abut;
9 and 19 are retaining rings for preventing the regulating pieces 12 and 13 from coming off; 20 and 21 are hoses; one end of the hose 20 is connected to the joint 11, the other end is connected to the refueling nozzle 22, and one end of the hose 21 is connected to the joint 10. The other end is connected to a pump device (not shown). 23 is an elongated hole formed in the direction of the lower surface rail 4 of the cover 5, through which the joint 7 passes.

In the above configuration, when the hose 20 is pulled to the end of the rail 4 in order to supply oil to a distant place as shown by the two-dot chain line in FIG.
moves along with the regulating piece 12 to the position indicated by the two-dot chain line at the right end in FIG. Since the regulating piece 12 is always urged in the direction of pulling each other by the regulating piece 13 and the spring 16, the carrier C will be further stretched against the urging of the spring 16, and the hose 20 will be stretched during refueling. There is always a force acting on it that pulls it back.

When refueling is completed and the tension on the hose 20 is released, the spring 16 contracts and the regulating piece 12 pulls the carrier C, that is, the hose 20, back to the left end of the elongated hole 14 shown by the two-dot chain line in FIG.

These effects are similar when the carrier C moves to the left end of the rail 4.

(E) Effect Since the configuration is as detailed above, when the hose is pulled, the hose moves a large distance, allowing refueling to a long distance, and when refueling is completed and the pulling force is released, the hose returns to a safe position. There is no risk of the hose being caught by a car when not refueling, and a single spring connects the regulating pieces at both ends that return the hose, which simplifies the structure with fewer parts and allows the use of longer springs. Therefore, it is possible to obtain an easy-to-use device in which the change in pullback force can be set small compared to the displacement distance of the hose.
