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. As a result, the refueling range was limited to a circle centered on the base and the radius of the hose.

Therefore, by moving the base support of the refueling hose outside the case, the applicant developed a refueling device that could expand the reach of the nozzle valve at the tip, that is, the refueling range.
I filed an application for Publication No. 112514.

This involves creating a horizontal hole in the front or side of the refueling machine case, inserting the hose into the long hole, letting the hose slack inside the case, and fixing the base.
The hose is fixed in the middle to a moving piece that moves along the pore, keeping the exposed length of the hose constant.

In the case disclosed in JP-A-53-112514, the hose slack inside the case is U-shaped at the top and bottom, but since there are other devices inside the case, sufficient space cannot be secured. , 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 is connected via a joint to the refueling pipe that stands up in the upper part of the case, and the middle part of the refueling hose is further raised inside the case and curved into an inverted U-shape, and then the joint is connected. It is also conceivable that the joint portion be led out of the case through the joint, and that this joint portion slides along the case. (Akira Jitsuka
(Refer to No. 59-126900 and Japanese Utility Model Application Publication No. 59-143998.) In this way, by curving the hose into an inverted U-shape to ensure slack, the slack can be taken care of by stretching the entire case upward. This allows you 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 within the case also becomes longer.As a result, a case large enough to accommodate such a hose is required, and the case becomes larger. do.

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 curved inside the case and raised must be sufficiently long. It is difficult to make it long, and as a result, the sliding length of the hose becomes short, and the expansion of the refueling range becomes small.

In addition, Japanese Utility Model Application Publication No. 58-1000 shows a hose in which the movement of the hose is held by rollers, 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 the slack in the hose, and 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.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
When moving the base support of the refueling hose outside the case, the length of the refueling pipe or refueling hose inside the case required for movement can be ensured to provide a sufficient moving distance, and the case It is an object of the present invention to provide a refueling device that does not require a large-sized hose and can smoothly move a hose.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a refueling pump, a motor connected to the refueling pump, a flow meter,
The lower case houses the flow pulse oscillator attached to the flow meter and the control box containing the refueling control equipment, and the outer part houses the nozzle hook that houses the refueling amount display meter and has a nozzle switch that is activated by opening and disconnecting the nozzle valve. In a refueling system that is divided into an upper case formed in the upper case and a top case formed so as to protrude forward above the upper case, the refueling pipe that stands up on the side inside the top case from the upper case is connected to a fixed joint. Connect to the oil supply pipe for extension through the pipe and lead it horizontally into the inside of the top case, and connect to the end of the oil supply pipe for extension via a swivel joint so that it is located above and parallel to the oil supply pipe for extension. The other end of the hose is connected to one end of the hose, and the other end of the hose is made to protrude from an elongated hole extending almost the entire length in the width direction provided on the side of the top case. A guide rail connected to a refueling hose having a refueling nozzle through a joint and parallel to the elongated hole, and a roller projecting horizontally from the joint of the refueling hose are fitted into the groove of the guide rail. The gist of the present invention is that a lateral movement mechanism for the coupling of the refueling hose, which is comprised of a moving means, is provided on the outside of the top hose.

[Effect]

According to the present invention, the connection hose that connects the inner side of the case to the rising oil supply pipe and is bendably connected to the horizontally guided extending oil supply pipe with the swivel joint is connected to the connecting portion of the connection hose. A slight rotation of the swivel joint will cause the refueling hose connection outside the case to slide significantly. Therefore, the connection part of the refueling hose can be moved via the lateral movement mechanism with a small amount of force, and the rotation range of the rotating part of the moving mechanism inside this case is small, so the refueling hose can be moved efficiently. Can do slides.

〔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 1 is divided into a lower case 2, an upper case 3, and a top case 4 formed to protrude forward on the upper case 3. 5', making it a double type.

Inside the lower case 2, there is a fuel pump 6;
A motor 7 connected to the flowmeter 8, a flow rate pulse transmitter 9 attached to the flowmeter 8, and a control box 10 containing a refueling control device are housed inside the upper case 3, and a refueling amount indicator 11 and a refueling amount indicator 11, which will be described later, are housed inside the upper case 3. The nozzle switch 12 is stored.

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 of 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.

In addition, a nozzle hook 14 is attached to the outside of the upper case 3.
A nozzle switch 12, which is operated by turning on and off a nozzle valve 15 attached to the tip of the oil supply hose 5, 5', is placed near the nozzle switch 12.

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, and extends to the center of the case 4. One end of a connecting hose 18 using a strong hose with wire is connected to the end of this extending oil supply pipe 13' via a swivel joint 17, and the other end of the connecting hose 18 is connected to the side of the case 4. It protrudes outward from an elongated hole 19 extending almost the entire length in the width direction, and is connected to the base of the refueling hose 5 via a joint part 20.

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

The joint portion 20 includes an upper joint 21a that is a first elbow and a lower joint 21 that is a second elbow that is attached at a certain angle to the joint 21a.
b and a joint 21c, which is a third elbow rotatably connected to the joint 21b, in a crank shape.

On the other hand, on the outside of the case 4, a channel member 22a,
A guide rail 22 is provided in which the opening surfaces of the grooves 22c are opposed to each other, and the rollers 23a with bearings protruding in the lateral direction of the cart 23 are connected to the channel member 2.
2a, 22b in the grooves 22c. Note that the rail 22a-1 of the channel member 22a on one side of the guide rail has approximately the same width as the roller 23a,
Rail 22b-1 of the other channel member 22b
is made larger than the width of 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
As shown by the dotted line in FIG. 4, the joint 21b is selected so that it protrudes outward to the maximum when the trolley 23 is located approximately at the center of the guide rail 22 and above the nozzle hook 14. The hose 18 has a length that maintains its curved state to some extent even when the cart 23 is located at the end of the guide rail 22, that is, it is longer than the longest straight distance between the swivel joint 17 and the guide rail 22.

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 a bottom part 25 that is integrated with the case 4. A hose guard 29 without corners is horizontally attached directly below the nozzle hook 14 on the side of the hose guard 29 using a metal half-ring so as to slightly protrude beyond the nozzle hook 14.

A semi-transparent part 26 is provided on the front surface of the case 4, and illuminators 27, 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, and 4 as a mechanism to be connected to the refueling hose 5'. In addition, indicators 11 and 11' are provided on both the front and back sides of the refueling machine 1.

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 portion 20 also moves accordingly, and the refueling area becomes oval, making it possible to widen the refueling area by that much more than in the past.

A signal emitted from the nozzle switch 12 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, and the display meter 11 returns to zero and the pump drive motor 7 is turned on. It is driven and 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 of the control box 10, and the oil supply amount is displayed on the display meter 11. be done.

In this way, the roots of the hoses 5 and 5' move freely on the sides of the case 4 for refueling, but the trolley 2
3 is located at the center of the guide rail 22, the joint 21c protrudes to the maximum outside of the case 4 as described above, so the hoses 5, 5' are separated from the side of the case 4 by that amount, and the nozzle hook 14 There is no risk of it getting tangled. 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 hoses 5, 5' tries to touch the corner of the nozzle hook 14, the hose Guard 29 deflects this and prevents damage.

After refueling, set the nozzle valve 15 to the nozzle hook 1.
4, the output from the nozzle switch 12 changes, the motor 7 and pump 6 stop, and the entire refueling operation is completed. The connecting hose 18 fixed on one side of the swivel joint 17 automatically moves to either end of the guide rail 22 due to the elastic force of the connecting hose 18 that tries to stretch from its curved state, so the hoses 5 and 5' are twisted and the nozzle It is possible to prevent the valve 15 from getting in the way of being attached or removed.

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 1 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 within the case required for movement, and can obtain a sufficient movement distance. There's no need to do that.

In addition, when moving the refueling hose, the connection hose that connects to the refueling hose that has the refueling nozzle above the case should be connected to the refueling pipe that extends inside the case by connecting its end into the case via a swivel joint. Since the connection hose can be connected and rotated horizontally, the connection hose can be moved horizontally by slightly rotating the connection part using the swivel joint of the moving mechanism.
Furthermore, since it is only necessary to move the rollers on the guide rails, only a small amount of force is required, and the operation can be performed easily and reliably with fewer failures.
