Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a refueling device used at a refueling station in which a hose is movable in order to expand the refueling range.

(b) Prior Art In recent years, automobiles have become larger and the nozzle of the refueling device cannot reach them depending on where they are parked. This is because the length of the hose including the nozzle is stipulated by law to be within 3m. Attempts have been made to increase the distance by moving the parts horizontally. On the other hand, for safety reasons, refueling equipment is supposed to be installed on a raised area called an island, and if part of the refueling equipment case protrudes from the island, there is a risk of it being hit by a car passing by. It's hot and undesirable. Therefore, the dimensions of the refueling device case have become narrower than the width of this island, and the moving distance of the hose outlet has to be smaller than this dimension.

(c) Purpose The purpose of the present application is to further expand the refueling range by moving the hose lead-out part beyond the width of the island with a simple structure, and to obtain a refueling device that does not have the risk of being caught by a car. .

(d) Structure and operation The structure for achieving the above purpose includes a fixed rail that is supported horizontally at a predetermined height by a support member installed on an island on the earthen floor, and a fixed rail that covers the fixed rail. It has a fixed case with a notch formed along the fixed rail, while the pump,
In a device in which a downstream pipe line of a flowmeter is led out from the notch and this lead-out part is driven by a carrier that moves along the fixed rail, the carrier can be moved by sliding in the extension direction of the fixed rail. A movable rail disposed on the movable rail, a means for biasing the movable rail in a direction that reduces the combined growth of the fixed rail and the movable rail, and a movable case fixed to the tip of the movable rail, When the hose is pulled beyond the range of the fixed rail, the carrier is transferred to the movable rail and the movable rail is displaced along with the movable case, and when the pulling force is released, the movable rail and movable case return to their original positions.

(e) Embodiment 1 is a refueling device, which is installed on an island I raised on a dirt floor G, and a pump and a flow meter (both not shown) are installed at the bottom of a vertically extending column 3 serving as a supporting member. ), but there is a display section 4 in the middle that shows the amount of refueling, etc.
However, a hose moving device 5 is provided at the top.

Reference numeral 6 denotes a fixed rail fixed to the column 3 and having a rectangular cross section; 7 has an end 8 having the same external dimensions as the rail 6; and a fixed rail 7 that slides within the rail 6, which is slightly smaller than the inner dimension of the rail 6. This is a moving rail on which a sliding portion 9 is formed.

10 is a protrusion planted in the rail 6;
The rail 7 is fitted into an elongated hole 11 bored in the sliding portion 9 of the rail 7, and the rail 7 can slide on the rail 6 within the range of this elongated hole 11.

Reference numeral 12 denotes a spring, one end of which is hooked onto a shaft 13 spanning between opposing inner surfaces of the rail 7, and the other end of which is disposed at the end of the rail 6 opposite to the deployed end of the rail 7, and is connected to the rail 7. The other movable rail 7', which has the same structure and is not shown, is mounted at the same location so that both rails 7, 7' are pulled together, that is, both rails 7, 7' are pulled into the fixed rail 6, and the total length of the rail is shortest. It is strong.

Reference numeral 14 denotes a hose, one end of which is connected to a pipe extending from a flow meter (not shown), and the other end connected to a refueling nozzle 15.

16 is the carrier and rail 6 or rail 7
four rollers 17 that roll between the two, a base plate 18 to which the rollers 17 are attached, and a hose
The hose holder 19 holds the intermediate portion of the hose holder 19 and is swingable relative to the base plate 18.

A notch 21 through which the hose 14 passes is formed over the entire length of the lower surface of the column 3 in the direction along the rail 6.
A fixed case 22 is a movable case that covers the rail 6 fixed to the fixed case 22, and the inner dimension thereof is slightly larger than the outer dimension of the fixed case 20. A notch 23 is also formed in the part along the notch 21 of the fixed case 20, and a screw 24 is formed in the fixed case 22.
It is fastened to a flange plate 25 which is welded to the end face of the rail 7. Note that the moving case 22 and the moving case 22' have the same structure.

In the above configuration, as explained earlier, the rails 7 and 7' are pulled together by the spring 12, so when not refueling, the case 22 fastened to the rails 7 and 7' as shown in FIG. ，
The distance L between both ends of the island 22' is equal to or slightly shorter than the width l of the island I.

When refueling, when the hose 14 is pulled, the carrier 16 first contacts the flange plate 25, and when the hose 14 is further pulled, the sliding part 9 of the rail 7 is pulled out from the rail 6 against the elasticity of the spring 12, and the carrier 16 is pulled out from the rail 6 against the elasticity of the spring 12. 7 moves with the case 22, that is, the carrier 16 moves with it, so that the nozzle 15 has a longer reach. Refueling is performed in this state (the state shown by the two-dot chain line in Fig. 1 and the state shown in Fig. 4), and after the refueling is completed, the nozzle 15 is returned to the position shown in Fig. 1 to release the tension on the hose 14, and the elasticity of the spring 12 is Therefore, the sliding portion 9 of the rail 7 is pulled back into the rail 6 and returns to its original state (the solid line position in FIG. 1 and the state shown in FIG. 2).

In addition, in this embodiment, when refueling is carried out by extending the movable rail 7, the hose 14 must be constantly pulled against the elasticity of the spring 12. A click stop mechanism or the like may be provided at a plurality of locations so that the rails 6 and 7 are stopped at any position when the rail 7 is pulled out.
When the rail 7 is returned to its standby position during non-lubrication, the previous lock is released and the sliding part 9 of the rail 7 is automatically moved to the rail 6.
It is also possible to configure it so that it is pulled back inward. Further, the moving case 22 does not need to have a box shape that always maintains its regular shape, but can also have a bellows shape that can be expanded and contracted with one end fixed to the rail 7 and the other end fixed to the case 20.

(F) Effect As detailed above, since the moving rail moves with the moving case and is biased in the direction of shortening the overall length of the rail, the case that houses the carrier and rail when not refueling is used. Even if the outer dimensions of the case are set to be equal to or shorter than the width of the island for safety reasons, when the hose is pulled during refueling, the case will be extended along with the rail, expanding the refueling range, and when not refueling, it will return to its original size. Since it returns to its outer dimensions, there is no risk of an accident such as being caught by a car when passing by, and since the rail moves along with the case, a refueling device that is pleasing in appearance can be obtained.
