Abstract

PURPOSE:To make efficient sliding of an oil-feeding hose possible by a method wherein a connecting hose is joined in a way of being capable of bending in a top case with a swivel joint to an extension pipe for oil supply that is connected to an oil supply pipe erected inside the case and is extended horizontally. CONSTITUTION:One end of an oil supply pipe 13 is connected to an oil supply pipe 13' with a fixed joint 16 in a top case 4 and is extended to the center of the top case 4. One end of a strong wire-reinforced connecting hose 18 is connected to the end of the extended oil supply pipe 13' with a swivel joint 17 and the other end thereof is projected outside through a long slit 19 that is provided on the side of the case in a length extending over almost all of its breadthwise length, and is connected to the base of an oil-feeding hose 5 with a joint 20. With an arrangement as mentioned above, the connecting hose 18 becomes able to make horizontal swiveling in the top case around the fixed joint 16 on its one end, and thereby the joint 20 connecting the oil-feeding hose on the other end of the connecting hose 18 becomes able to make a wide-ranged movement, requiring less force for the movement and assuring easy and precise operation with less possibility of breakdown.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ground-fixed refueling device used at automobile gasoline refueling stations and the like.

[Conventional technology]

In such fixed refueling devices, the root of the refueling hose with 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 determined that
The refueling area was limited to a circle with the base as the center and the radius of the hose length.

Therefore, by moving the base support of the refueling hose outside the case, we have created a refueling device that can expand the reach of the nozzle valve at the tip, that is, the refueling range.
The applicant previously filed an application for JP-A-53-112514.

This is done by providing a horizontal hole in the front or side of the refueling machine case, inserting the hose through the hole, letting the hose slack in the case to fix the base, and attaching it to a movable piece that moves along the hole. The hose is fixed in the middle, keeping the exposed length of the hose constant.

In this Japanese Patent Application Publication No. 53-112514, the slack of the hose inside the case is U-shaped at the top and bottom.
Since there are other instruments inside the case, it is not possible to secure sufficient space, and it is not possible to take up a large amount of slack in this hose.

On the other hand, the root part of the refueling hose was connected via a joint to the refueling pipe raised in the upper part of the case, and the middle of the refueling hose was further raised inside the case to form an upside down U-shape.
It is also conceivable that it is led out of the case via a joint, and that this joint portion slides along the case. (Utility Model Application No. 59-126900, Utility Model Application No. 59-14
(Refer to Japanese Patent Publication No. 3998) In this way, by curving the hose into an inverted U-shape to ensure slack, the entire case can be stretched upward to secure storage space.

[Problem to be solved by the invention]

However, as the slide length becomes longer, the length of the hose that is curved into an inverted U-shape inside the case also becomes longer.
As a result, a case large enough to accommodate such a hose is required, resulting in an increase in the size of the case.

Furthermore, in any of these cases, if the position where the oil supply pipe rises into the case is close to the position where the hose leads out of the case, the length of the hose that is raised cleanly inside the case must be adjusted. It is difficult to keep it long enough, and as a result,
The sliding length of the hose is also short, and the expansion of the refueling range is only slight.

In addition, a hose in which the movement of the hose is held by rollers is shown in Japanese Utility Model Application Publication No. 58-1000, but in this case, the upper part of the case is extended horizontally, and the hose is moved by rollers inside the case. This is to ensure that the case is sagging, but it also has the disadvantage of increasing the size of the case. Furthermore, the elasticity of the slack in the hose housed in the case also prevents the movement of the rollers, making it impossible to expect smooth hose movement.

An object of the present invention is to eliminate the disadvantages of the conventional example, and to secure a sufficient length of the refueling pipe or refueling hose inside the case when moving the root support part of the refueling hose outside the case. It is possible to obtain a long travel distance, and
Therefore, it is an object of the present invention to provide a refueling device that does not require a large case and allows smooth movement of a hose.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a main body case of a refueling device that includes a refueling pump, a motor connected to the refueling pump, a flow meter, a refueling amount display meter that displays the amount of refueling, and a refueling hose having a nozzle valve at the tip. A top case is provided on the top that extends horizontally from the main body case, and a fuel supply pipe is set up from the main body case to the side inside the top case, and an extension fuel supply pipe is connected to the fuel supply pipe through a fixed joint inside the top case. one end of the connection hose is connected to the end of this extension oil supply pipe via a swivel joint, and the other end of the connection hose is connected horizontally to the end of the extension oil supply pipe through a widthwise elongated hole provided on the side of the top case. The main feature is that a lateral movement mechanism is provided on the side of the top case to connect to a joint located at the top case, connect a refueling hose to the joint, and move the joint parallel to the elongated hole. be.

[Effect]

According to the present invention, the connection hose that connects the inner side of the case to the rising oil supply pipe inside the top case and is bendably connected to the extending oil supply pipe led horizontally by the fixed joint is connected to the connecting hose. The joint at the other end, which connects to the refueling hose outside the case, largely slides around the fixed joint at the other end.

Therefore, the joint part to the refueling hose can be moved via the lateral movement mechanism with a small force, and the refueling hose can be slid efficiently.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a partially cutaway front view showing an embodiment of the oil supply device of the present invention, Fig. 2 is a side view of the same, Fig. 3 is a longitudinal sectional side view of the main part, and Fig. 4 is a cross-sectional plan view of the same. In this embodiment, the ground-fixed refueling device l has a lower case 2 and an upper case 3 as its main body cases, and an end protruding forward and horizontally above the upper case 3 of the main case. It is divided into a top case 4 and has oil supply hoses 5.5' on the left and right sides, making it a double type.

In the lower case 2, a refueling pump 6, a motor 7 connected to the pump 6, a flow meter 8, a flow pulse transmitter 9 attached to the flow meter 8, and a control box lO containing a refueling control device are housed, In addition, there is a refueling amount indicator 1 inside the upper case 3.
1 and a nozzle switch 12 to be described later.

The pump 6 and the flow meter 8 are sequentially arranged in the middle of a fuel supply pipe 13 that communicates with an underground tank (not shown), and the fuel supply pipe 13 is connected inside the connecting column 30 between the lower case 2 and the upper case 3 and inside the upper case 3. In particular, inside the upper case 3, it is raised toward the side and its end protrudes into the top case 4.

Further, a nozzle hook 14 is formed on the outside of the upper case 3, and a nozzle switch 12 that is activated by removing the nozzle pulp hook 15 attached to the tip of the refueling hose 5, 5' is provided near the nozzle hook 14.
I placed it.

As shown in FIGS. 3 and 4, inside the top case 4, the end of the oil supply pipe 13 is connected to the oil supply pipe 13' via a fixed joint 16.
A connection hose 18 is connected to the oil supply pipe 13' and extends to the center of the case 4, and is connected to the end of the oil supply pipe 13' through a swivel joint 17 using a strong wire-containing hose.
One end of the connection hose 18 is connected to the case 4, and the other end of the connection hose 18 is connected to the case 4.
It is made to protrude outward from a long hole 19 provided on the side of the fuel supply hose 5 over almost its entire length, and is connected to the base of the oil supply hose 5 via a joint part 20.

The swivel joint 17 on the oil supply pipe 13' side is fixed by a fixing portion 28.

The joint portion 20 is rotatably connected to an upper joint 21a that is a first elbow, a lower joint 21b that is a second elbow that is attached at a certain angle to the joint 21a, and the joint 21b. Joint 21 which is the third elbow
It is composed of a crank-shaped combination with c.

On the other hand, on the outside of the case 4, a guide rail 22 made of channel members 22a and 22b with the opening surfaces of the grooves 22c facing each other is provided directly below and parallel to the elongated hole 19, and serves as a lateral movement mechanism for moving the carriage 23. The rollers 23a with bearings protruding laterally are connected to the channel members 22a, 22.
b into the groove 22c. Note that the rail 22a-1 of the channel member 22a on one side of the guide rail is the roller 2.
The width of the other channel member 22b is approximately the same as that of the other channel member 22b.
The rail 22b-1 is made wider than the roller 23a so that the cart 23 can move smoothly. The truck 23 has a hole in the center, and the joint part 20 is inserted through the hole.
Of these, the joint 21a or 21b was passed through and held rotatably.

Note that the coupling angle α between the joints 21a and 21b is the fourth
As shown by the dotted line in the figure, this truck 23 is connected to the guide rail 22.
The joint 21b is selected so that it protrudes outward to the maximum when it is located at the upper part of the nozzle hook 14 at approximately the center of the A length that maintains the curved state to some extent, ie, longer than the longest straight distance between the swivel joint 17 and the guide rail 22, is used.

Further, at the end of the guide rail 22, a stopper 24 for cushioning when the cart 23 comes into contact is formed using rubber or a spring, and the upper part of the guide rail 22 is covered with an eaves part 25 integrated with the case 4. Furthermore, the nozzle hook 14 is attached to the side of the case 4.
A hose guard 29 without corners was installed horizontally directly below the nozzle hook 14 using a metal half-ring so that it slightly protruded beyond the nozzle hook 14.

A semi-transparent part 26 is provided on the front surface of the case 4, and illuminators 27 and 27' such as fluorescent lamps are arranged inside the case 4.

By the way, although not shown in the drawings, since the refueling device 1 is of a double type, there is another set of the same mechanism as described above on the opposite side of the cases 2, 3.4 as a mechanism to be connected to the refueling hose 5'. Yes, and display meter 11.11' is fueling machine 1
It is provided on both the front and back sides.

Next, to explain how to use and operate, the connecting hose 18 inside the case 4 is rigid and exerts repulsive elastic force in a curved state, so the trolley 23 and the joint 20 held by it are always guided. It is located at one end of the rail 22, abutting a stopper 24.

To refuel, the nozzle valve 15 is removed from the nozzle hook 14 and inserted into the fuel filler port of the vehicle. At this time,
Since the truck 23 freely moves laterally on the guide rail 22, the joint part 20 also moves accordingly, and the oil supply area becomes an oval shape, making it possible to expand the oil supply area by that much more than before.

A signal from the nozzle switch 12 that is emitted when the nozzle valve 15 is removed is output to the motor 7 and the display meter 11 via the control equipment in the control box 10.
is returned to zero, and the pump driving motor 7 is driven to become ready for refueling. Therefore, when the nozzle valve 15 is opened, oil is refilled, and 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 oil amount is displayed on the display meter 11. be done.

In this way, the roots of the hoses 5 and 5' move freely along the sides of the case 4 for refueling, but when the trolley 23 is located in the center of the guide rail 22, the joint 21c moves along the side of the case 4 as described above. Since it protrudes outward to the maximum, hoses 5 and 5'
is separated from the side of case 4 by that amount, and nozzle hook 1
There is no risk of getting entangled with 4. Furthermore, when the trolley 23 and the joint part 20 are located at one end of the guide rail 22 and refueling is performed in front of the other end, if the middle of the refueling hose 5.5' tries to touch the corner of the nozzle hook 14, the hose Guard 2
9 to deflect it and prevent it from being damaged.

After refueling, if you apply the nozzle valve 15 to the nozzle hook 14, the output from the nozzle switch 12 will change, the motor 7 and pump 6 will stop, and the entire refueling operation will be completed. The trolley 23 and the joint 20 automatically move to either end of the guide rail 22 due to the elastic force of the connecting hose 18, whose one end is fixed to one side of the swivel joint 17, trying to extend from the curved state. It is possible to prevent the hose 55' from becoming kinked and obstructing the nozzle valve 15 from being unlatched.

Since the light from the illuminators 27, 27' brightly illuminates the front surface through the translucent portion 26, there is also an advertising effect that makes the refueling device l itself noticeable.

〔Effect of the invention〕

As described above, the refueling device of the present invention can secure a sufficient length of the connection hose required for movement within the top case above the main body case, and can obtain a sufficient travel distance of the refueling hose. There is no need to make the main body case large.

In addition, as a result of the connection hose turning horizontally around the fixed joint at one end of the top case, the joint at the other end of the connection hose to the refueling hose can be moved widely, resulting in large movements of the refueling hose. is obtained.

Furthermore, since this movement is carried out via a horizontal movement mechanism, only a small amount of force is required, and the operation can be performed easily and reliably with fewer failures.
