A is provided with a refueling amount display 3 for displaying the refueling amount measured by the flow meter.

At the upper end of the side surface 2b of the refueling device main body 2, there is provided a joint 5 for connecting a pipe line connected to the pump and the refueling hose 4, and at an intermediate position of the side surface 2b of the refueling device main body 2, There is provided a nozzle storage section 7 in which an oil supply nozzle 6 connected to the end of the hose 4 is stored.

A hose storage section 8 is provided below the nozzle storage section 7 for storing the fuel supply hose 4 hanging down from the fuel supply nozzle 6. The nozzle housing 7 and the hose housing 8 are concave portions provided on the side surface 2b of the fueling device main body 2, and are surrounded by panels 7a and 8a, respectively, and the fueling nozzle 6 and the fueling hose 4 are connected to the side surface 2b of the fueling device main body 2. It is formed so as not to protrude from.

That is, the nozzle accommodating portion 7 is formed in the fueling device main body 2 from the side surface 2b, and the nozzle accommodating portion 7 is provided with a nozzle hook 9 for engaging the oiling nozzle 6. The side surface 2b on the side of the nozzle hook 9 (right side in FIG. 2).
, A hose regulating member 10 formed in a U-shape is attached. Therefore, the oil supply hose 4 hanging down from the joint 5 is connected to the nozzle stopper 9 by the hose restricting member 10.
It is regulated so as to be suspended at a more distant position, and hangs down so as not to hinder the removal and return operations of the refueling nozzle 6.

As shown in FIG. 3, the nozzle hook 9 comprises a pipe insertion portion 11 into which the discharge pipe 6a of the refueling nozzle 6 is inserted and a lever guard insertion portion 12 into which the lever guard 6b of the refueling nozzle 6 is inserted. Become. Pipe insertion part 11
In order to facilitate the insertion of the discharge pipe 6a, a margin is provided in the vertical and horizontal directions so that the discharge pipe 6a can be displaced. Further, the lever guard insertion portion 12 holds the lever guard 6b of the refueling nozzle 6 without looseness.
It has a holding groove 13 into which the lever guard 6b fits.

The holding groove 13 is provided with a lever guard 6 to prevent the operator from accidentally grasping the nozzle lever 6c of the refueling nozzle 6 and opening the main valve when refueling work.
b is manufactured so as to dive into the holding groove 13.

The nozzle hanger 9 is a bracket 15 rotatably supported on a shaft 14 fixed to the fueling apparatus main body 2.
And a pin 17 to which one end of a coil spring 16 is hooked. When the refueling nozzle 6 is hooked, it rotates to the nozzle storage position as shown by a broken line in FIG. During the refueling operation, the nozzle rotates to the nozzle removal / return position indicated by the solid line in FIG. The other end of the coil spring 16 is a pin 1
8 and urges the nozzle hook 9 to be held at the nozzle storage position or the nozzle removal / return position.

The pins 17 and 18 are provided in the nozzle housing 7.
Is provided at a lower end 19a of a support member 19 fixed to the fueling device main body 2 so as to extend downward from the top plate.

As shown in FIG. 4, at the time of refueling before or after refueling, with the refueling nozzle 6 hooked on the nozzle hook 9, the nozzle hook is held until the upper end of the bracket 15 contacts the inside of the side surface 2b. 9 is rotated in the A direction. That is,
When the operator returns the refueling nozzle 6 to the nozzle hook 9, the operator presses the refueling nozzle 6 in the Xa direction while holding the grip 6 d of the refueling nozzle 6 and pushes it into the nozzle housing 7.

The nozzle hook 9 is urged in the direction A by the tensile force of the coil spring 16 and is held at the nozzle storage position shown in FIG. As described above, since the nozzle hook 9 and the refueling nozzle 6 are housed in the nozzle housing portion 7, the nozzle hanger 9 and the refueling nozzle 6 are held so as not to protrude from the side surface 2 b of the fueling device main body 2. Thereby, the refueling hose 4 hanging down from the refueling nozzle 6
Is stored in the hose storage unit 8.

Therefore, for example, when a worker performs a refueling operation near the refueling apparatus 1, the worker does not hit the nozzle hook 9, the refueling nozzle 6, or the refueling hose 4 hanging down from the refueling nozzle 6, and especially the automobile of the customer. Arrives at both the front side and the rear side of the refueling device 1, the worker moves back and forth between the front side and the rear side of the refueling device 1 through the side of the side surface 2 b of the fueling device main body 2. The hook 9 or the refueling nozzle 6 does not hinder the refueling operation. Further
When the fuel is not supplied, the nozzle hook 9 is hidden in the nozzle housing 7.
The oil supply hose 4 in this state.
Can be stored in the hose storage section 8, so that
The nozzle 6 and the oil supply hose 4 are in the nozzle housing 7 and the hose
Refueling nozzle stored in storage section 8 and hooked on nozzle hook 9
The movement of the worker is hindered by the chisel 6 and the refueling hose 4.
Is prevented.

The nozzle hook 9 and the refueling nozzle 6 are stored in the nozzle storing portion 7 of the refueling device main body 2 when the refueling station is closed, the refueling device is cleaned, and maintenance is performed. Can be performed. Moreover, since the nozzle hook 9 and the fueling nozzle 6 can be stored in the nozzle housing portion 7 of the fueling apparatus main body 2 even when the gas station is in business, the nozzle hook 9 which is used less frequently is used.
In addition, the refueling nozzle 6 can be protected.

When refueling, the user pulls out in the Xb direction while holding the grip 6d of the refueling nozzle 6 housed as shown in FIG. Thereby, the nozzle hook 9 rotates counterclockwise (direction B) about the shaft 14 to reach the nozzle removal / return position shown in FIG. At this time, the protrusion 20 protruding from the lower end of the nozzle hook 9 comes into contact with a stopper 21 provided on the side surface 2b of the fueling device main body 2, thereby restricting rotation in the counterclockwise direction (B direction). Further, the nozzle hook 9 is urged in the direction B by the tensile force of the coil spring 16, and is held at the nozzle removal / return position shown in FIG.

When the nozzle hook 9 is at the nozzle removal / return position, the grip 6d of the refueling nozzle 6 protrudes from the side surface 2b of the refueling device main body 2, so that the nozzle removal and nozzle returning work becomes easy. When the refueling nozzle 6 is removed from the nozzle hook 9 for refueling, the lever guard insertion portion 12 of the nozzle hook 9 protrudes from the side surface 2b of the refueling device main body 2. It does not get in the way.

As shown in FIG. 5, when the nozzle hook 9 is rotated to the nozzle storing position or the nozzle removing / returning position as described above, the coil spring 16 centered on the pin 18 when the total length of the coil spring 16 is constant. The rotation trajectory of the tip 16 is a curve like an arc a (a, b, c), and the actual rotation trajectory of the pin 17 about the shaft 14 is an arc b (a,
b ′, c ′). Thus pin 17
Since the shaft 14 which is the center of rotation of the coil spring 16 and the pin 18 which is the center of rotation of the coil spring 16 are displaced from each other, the tensile force of the coil spring 16 is maximized at the middle position b ′ of the arc b, and the nozzle storage position or It becomes minimum at the rotation positions a and c ′ of the pin 17 at the nozzle removal / return position.

Accordingly, the tensile force of the coil spring 16 acts in a toggle manner at the middle position b 'of the arc b, and when the pin 17 is at the position a, the nozzle hook 9 is urged in the direction A and the pin 17 is pushed. Is at the position c ′, the nozzle hook 9 is set to B
Bias in the direction. Therefore, when the nozzle hook 9 is at both the nozzle storage position and the nozzle removal / return position, the nozzle spring 9 is held at that position without rattling by the tensile force of the coil spring 16.

FIGS. 6 and 7 show a second embodiment of the present invention.

FIG. 6 shows a state where the nozzle hook 9 is held at the nozzle removal / return position, and FIG. 7 shows a state where the nozzle hook 9 is held at the nozzle storage position.

The nozzle holder 9 has a bracket 15 rotatably supported on a shaft 14 similarly to the first embodiment, and is rotatably provided in the nozzle housing 7. And
It is held at its rotational position by an urging mechanism 24 composed of a coil spring 22 and a link 23.

One end of the coil spring 22 of the urging mechanism 24 is hooked on a pin 25 fixed to the inner wall of the nozzle housing 7, and the other end is a hook pin 23 provided on one end of a link 23.
a. The link 23 is rotatably supported by a shaft 26 fixed to the inner wall of the nozzle housing 7, and a connecting pin 23b is provided at the other end.

The link 23 has a connecting pin 23b connected to an upper portion of the nozzle hook 9, and rotates in accordance with the turning operation of the nozzle hook 9. Therefore, when the nozzle hook 9 is at the nozzle removal / return position, the urging mechanism 24 urges the link 23 counterclockwise when the locking pin 23a of the link 23 is located above the shaft 26. I do. As a result, the nozzle hook 9 is held in a state where the protrusion 20 at the lower end is in contact with the stopper 21 as shown in FIG.

However, when the nozzle hook 9 is in the nozzle storage position, the urging mechanism 24 moves the locking pin 2 of the link 23.
3a is located below the shaft 26 and urges the link 23 clockwise. As a result, the nozzle hook 9 is held in a state housed in the nozzle housing part 7 as shown in FIG.

Therefore, when no oil is supplied, as shown in FIG.
When the nozzle hook 9 is rotated in the direction A and pushed into the nozzle housing 7 with the refueling nozzle 6 hooked on the nozzle hook 9, the link (indicated by a broken line in FIG. 7) 23 is turned clockwise. Rotate. Therefore, the nozzle hook 9 is urged in the direction A by the tensile force of the coil spring 22 via the link 23, and is held at the nozzle storage position where the upper end of the bracket 15 contacts the inside of the side surface 2b.

As described above, since the nozzle hook 9 and the refueling nozzle 6 are housed in the nozzle housing part 7, they are held in a state where they do not protrude from the side surface 2b of the fueling apparatus main body 2. Therefore, for example, when an operator performs refueling work near the refueling device 1, the nozzle hook 9 or the refueling nozzle 6 does not hinder the refueling operation, thereby facilitating the refueling operation.

When refueling, the user pulls out in the Xb direction while holding the grip 6d of the refueling nozzle 6 housed as shown in FIG. As a result, the nozzle hook 9 rotates counterclockwise (direction B) about the shaft 14 to reach the nozzle removal / return position shown in FIG. At this time, since the link 23 rotates counterclockwise, the nozzle hook 9 is urged in the direction B by the tensile force of the coil spring 22 via the link 23. Further, the protrusion 20 projecting from the lower end of the nozzle hook 9 comes into contact with a stopper 21 provided on the side surface 2b of the oil supply device main body 2, and the rotation in the counterclockwise direction (B direction) is regulated.
Then, the nozzle hook 9 is held at the nozzle removal / return position shown in FIG. 6 by the tensile force of the coil spring 22.

As shown in FIG. 8, when the nozzle hook 9 is rotated, the rotation trajectory of the other end of the coil spring 22 when the length is constant becomes an arc C (a, b, c). Link 2
The rotation trajectory of the third retaining pin 23a is circular arc d (a, b ',
It becomes like c).

When the hook pin 23a of the link 23 passes through the point b ', the difference L between the arc C and the arc D becomes maximum, and the tensile force of the coil spring 22 becomes maximum. However,
When the locking pin 23a passes through the point b ', the locking pin 23
Since a, the shaft 26 and the pin 25 are located on a straight line, b ′
The point becomes the dead point of the link 23.

Accordingly, when the pin 23a is located above the point b ', the urging mechanism 24 urges the nozzle hook 9 in the direction B as shown in FIG. , The nozzle hook 9 as shown in FIG.
Is biased in the direction A to apply a spring force in a toggle manner at the point b ′.

FIGS. 9 to 11 show a third embodiment of the present invention.

In each of the drawings, if the nozzle hook 9 is stored in the nozzle housing section 7 during refueling, it becomes difficult to return the refueling nozzle 6 to the nozzle hook 9. In this case, the worker pulls the nozzle hook 9 at the one end storage position in the Xb direction to move the nozzle hook 9 to the nozzle removal / return position, and then returns the refueling nozzle 6 to the nozzle hook 9, which is troublesome.

For this reason, in the present embodiment, a nozzle detecting plate 27 for detecting that the discharge pipe 6a of the refueling nozzle 6 has been inserted is provided behind the pipe insertion portion 11 of the nozzle hook 9. The nozzle detection plate 27 is provided at the pipe insertion portion 1.
1 has a shaft 28 rotatably supported on the side wall of the nozzle hook 9 and is urged in a counterclockwise direction by a spring force of a torsion spring 29 wound around the shaft 28. I have. Therefore, when the discharge pipe 6a of the refueling nozzle 6 is not inserted into the pipe insertion portion 11 of the nozzle hook 9, the nozzle detection plate 27 is held in a hanging state.

When the discharge pipe 6a of the refueling nozzle 6 is inserted into the pipe insertion portion 11 of the nozzle hook 9, the tip of the discharge pipe 6a contacts the nozzle detection plate 27, and rotates the nozzle detection plate 27 clockwise. Move. Therefore, when the nozzle detecting plate 27 rotates clockwise against the spring force of the torsion spring 29, the refueling nozzle 6 is
Can be detected.

One end of a shaft 28 provided integrally with the nozzle detection plate 27 protrudes to the side of the nozzle hook 9, and a hook 30 extending in the same direction as the nozzle detection plate 27 is provided at the end. It is provided integrally. Therefore, when the nozzle detection plate 27 is pressed by the discharge pipe 6a and rotates clockwise, the hook 30 also rotates in the same direction.

Reference numeral 31 denotes a rotation restricting member for restricting the rotation of the nozzle hook 9, which is fixed to the inner wall of the nozzle housing 7 so as to be located above the hook 30. The rotation restricting member 31 is a rod-shaped member, and is attached so as to extend obliquely in the vertical direction according to the rotation direction of the nozzle hook 9.

Therefore, when the fuel is not supplied, the discharge pipe 6a of the fuel supply nozzle 6 is connected to the nozzle hook 9 as shown in FIGS.
And the tip of the discharge pipe 6a rotates the nozzle detection plate 27 clockwise. Thus, in a state where the refueling nozzle 6 is hung on the nozzle hook 9,
When the nozzle hook 9 is rotated in the direction A and pushed into the nozzle housing 7, the nozzle hook 9 is urged in the direction A by the tensile force of the coil spring 16 and is held at the nozzle housing position.

At this time, since the hook 30 integrated with the nozzle detection plate 27 is also rotating clockwise, the hook 30 passes through without contacting the rotation restricting member 31 and
Is allowed to rotate to the nozzle storage position.

However, when the nozzle hook 9 is pressed into the nozzle housing 7 without returning the fuel nozzle 6 to the nozzle hook 9, the discharge pipe 6a of the fuel nozzle 6 is inserted into the pipe insertion portion 11 of the nozzle hook 9. As a result, the nozzle detection plate 27 is in a hanging state, and the hook 30 is also oriented in the same direction. Therefore, even if the nozzle hook 9 is pressed into the nozzle housing section 7 during refueling, the hook portion 30a of the hook 30 is moved to the rotation restricting member 31 when the nozzle hook 9 rotates to the position shown by the broken line in FIG. The rotation of the nozzle housing 7 into the nozzle housing 7 is prevented.

As described above, the hook 30 and the rotation restricting member 31
This prevents the empty nozzle hook 9 from retracting into the nozzle accommodating section 7 without the refueling nozzle 6 being returned, so that the nozzle returning operation after the refueling is completed can be easily performed.

In the above-described embodiment, the fuel supply device 1 in which one nozzle hook 9 is provided on the side surface 2b of the fuel supply device main body 2 has been described as an example. However, the present invention is not limited to this. It is needless to say that the present invention can be applied to an oil supply device having a configuration in which a plurality of nozzle hooks 9 are provided.
