Description

Description: [Industrial field of application] The present invention relates to a ground-fixing type fueling device used in a gasoline service station or the like.

[Conventional technology]

In such a fixed refueling device, the root of the refueling hose having a nozzle valve at the tip is usually fixed to the upper side of the case, and the length of the refueling hose outside the case must be within a certain length by law. Since it is set,
The refuelable range is limited to the circle centered on the root and having the radius of the hose length.

Therefore, if the base support part of the refueling case can be moved laterally, the support center of the hose can be changed by this amount and the refueling range can be expanded, but this is large because the refueling pipe or the refueling hose moves. An opening must be provided in the case. The opening serves as a place where dust or rain, snow, and insects that gather in the illuminator provided inside enter, which is not preferable for maintenance of the refueling device.

An object of the present invention is to solve the disadvantages of the conventional example, and to provide a refueling device capable of exhibiting dust-proof, snow-proof, and insect-proof effects by closing the lateral movement opening of the hose root without blocking the movement of the hose. It is in.

According to the present invention, however, the object of the present invention is to provide a refueling pump, a motor connected to the refueling pump, a lower case containing a flow meter, an upper case containing a refueling amount indicator, and a forward case above the upper case. In a fueling device partitioned into a protruding top case, a fueling pipe connected to a flow meter in the lower case is guided horizontally into the top case, and a hose is connected to the end of this fueling pipe through a swivel joint. Of one end of the hose is connected to the other end of the hose, and the fitting part is protruded from a long hole provided on the side part of the top case and extending over almost the entire width direction, and an oil supply hose having a nozzle valve is connected to the tip of the fitting part. However, the joint portion of the oil supply hose is held on a carriage that travels on a guide rail that is provided in parallel with the elongated hole, and one end of each of the two bellows bodies is fixed to both ends of the guide rail. The fixed front and rear ends of the carriage, telescopic each bellows body is accomplished by at any state of the extension is formed to a size which closes the long hole.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially cutaway front view showing an embodiment of a fuel supply device of the present invention, and FIG. 2 is a side view of the same. As an example, a ground-fixed fuel supply device 1 includes a lower case 2, an upper case 3, and It is divided into a top case 4 formed so as to project forward on the upper case 3, and the nozzle valve 15 is provided at the left and right ends.
A double type was provided by including refueling hoses 5 and 5 '.

In the lower case 2, a refueling pump 6, a motor 7 connected to the pump 6, a flow meter 8, a flow rate pulse transmitter 9 attached to the flow meter 8, and a control box 10 containing a refueling control device are stored. In addition, in the upper case 3, the refueling amount indicator 11,1
1'and a nozzle switch 12 described later are housed.

The pump 6 and the flowmeter 8 are sequentially arranged in the middle of an oil supply pipe 13 communicating with an underground tank (not shown).
Is erected in the connecting column 34 of the lower case 2 and the upper case 3 and in the upper case 3, and the end thereof is projected into the top case 4.

In the top case 4, the end of the oil supply pipe 13 is connected to a horizontal oil supply pipe 13 'through a fixed joint 16 and extends to the center of the case 4, and the lower end is attached to the end of the oil supply pipe 13'. One end of a solid hose 18 containing a wire is connected via a fixed swivel joint 17, and the other end of the oil supply hose 18 is projected outward from a long hole 19 provided in a side portion of the case 4 and extending over substantially the entire width direction. A joint portion 20 with the base of the oil supply hose 5 is connected to this projecting portion, and the joint portion 20 or its vicinity is supported by a horizontal movement mechanism 21 provided in the lateral direction of the side surface of the case 4.

There are various types of horizontal movement mechanism 21, and one example thereof is shown in FIG.
A guide rail 22 is formed by making the opening faces of 22a and 22b face each other, and a roller 23 with a bearing protruding laterally of the carriage 23 is provided.
Place a in the channel members 22a, 22b. On the other hand, the joint part
Reference numeral 20 denotes a downwardly bent elbow 24 that is connected to the end of the hose 18 and a swivel joint 25 that is fitted to the elbow 24 and is rotatable in the up and down direction on the way. The portion 20 was pierced and held rotatably. 20 in the figure
Reference symbols a and 20b denote flanges for preventing the joint portion 20 from coming off.

Although not shown, the elbow 24 and the swivel joint
The connecting angle with 25, that is, the horizontal protrusion angle of the lower part of the swivel joint 25 with respect to the elbow 24,
It is chosen to project maximally outward when it is located in the center of 22, while the refueling hose 18 has
The length used to maintain the curved state to some extent only when it is located at the end of 22, that is, longer than the longest linear distance between the swivel joint 17 and the guide rail 22 is used.

The outside of the elongated hole 19 projects from the case 4 and is covered with an eave portion 26 which also serves as a support for the channel member 22b.

As shown in FIG. 4, one end of the guide rail 22 and the other end fixed to the front and rear ends of the carriage 23 are provided with bellows bodies 31 and 31 'along the guide rail 22. The opening formed between the members 22a and 22b is covered. In this case, the bellows bodies 31 and 31 'are formed so that the bellows bodies 31 and 31' close the elongated holes in any state in which the bellows bodies 31 and 31 'expand and contract as the carriage 23 moves.

In addition, the nozzle hook 14 is formed on the outer side of the upper case 3,
Place the nozzle switch 12 that operates by hooking and unhooking the nozzle valve 15 attached to the tip of the refueling hose 5, 5 ′ in the vicinity of it,
A hose hooking prevention guard 28 was formed by directly mounting a metal semi-circular body with rounded corners directly below the nozzle hook 14 so as to slightly project from the side of the nozzle hook 14.

A semi-transparent portion 29 is provided on the front surface of the case 4, and an illuminator 30 such as a fluorescent lamp is provided in the case 4.

By the way, although illustration is omitted, since the refueling device 1 is of a double type, the same mechanism as described above should be connected to the refueling hose 5'on the opposite side of the cases 2, 3 and 4 as another set. In addition, display meters 11 and 11 'are provided on both front and back surfaces of the refueling machine 1.

Next, the usage and operation will be explained. Since the refueling hose 18 in the case 4 is rigid and exerts a repulsive elastic force in a curved state, the carriage 23 and the joint portion 20 held by the carriage 23 are provided.
Is always located at one end of the guide rail 22.

To refuel, the nozzle valve 15 is removed from the nozzle hook 14 and inserted into the fuel filler port of the automobile. At this time, the trolley 23
Since the guide rail 22 is freely laterally moved, the joint portion 20 is also moved accordingly, and the refueling area becomes an elliptical shape, so that the refueling area can be expanded by a corresponding amount.

In this way, when the hose 18 and the joint portion 20 move, one bellows body 31 located in the traveling direction of the carriage 23 is pushed by the carriage 23 as the carriage 23 moves as shown in FIG. When contracted, the other bellows body 31 'stretches by being pulled by the movement of the carriage 23, and always moves in mutually opposite directions to always block the opening without obstructing the movement of the carriage 23. Therefore, it is possible to prevent the dust and the insects that try to collect in the night illuminator 30 from entering the case 4 at the portion of the bellows body 31.

Nozzle switch issued when nozzle valve 15 is removed
The signal from 12 is output to the motor 7 and the indicator 11 via the control device in the control box 10. The indicator 11 is returned to zero and the pump driving motor 7 is driven to be in a refuelable state. Therefore, if the nozzle valve 15 is opened, refueling is performed, the flow rate signal measured by the flow meter 8 and converted into a signal by the pulse transmitter 9 is counted by the control device in the control box 10, and the refueling amount is displayed on the display meter 11. To be done.

When the carriage 23 and the joint portion 20 are at one end of the guide rail 22 and fuel is to be fed in front of the other end, the fuel supply hose 5,
When the middle of 5 ′ tries to touch the corner of the nozzle hook 14, the guard 38 first touches the hoses 5, 5 ′ to prevent them from being deflected and to be caught in the nozzle hook.

After refueling, if the nozzle valve 15 is applied to the nozzle hook 14, the output from the nozzle switch 12 changes, the motor 7 and the pump 6 are stopped, and the refueling operation is completed, but when the nozzle valve 15 is applied in this way, Cart 23 and joint 20
Is a hose 18 with one end fastened to one of the swivel fittings 17.
Since the elastic force that tends to extend from the bent state automatically shifts to either end of the guide rail 22, the hoses 5 and 5'will not be twisted and will not interfere with the hooking and unhooking of the nozzle valve 15.

Since the light of the illuminator 30 illuminates the front surface brightly through the semi-transparent portion 29, there is an advertising effect that makes the refueling device 1 stand out.

As described above, the refueling device of the present invention is configured such that the base part of the refueling hose can be moved laterally so as to widen the refueling area. Even if the hose moves to any position without obstructing the movement, the bellows body that expands and contracts with it can be almost completely closed at all times, which allows dust and insects that try to collect in the illuminator to enter the case. Can be prevented.
