Summary of the Invention

Problems to be Solved by the Invention

[0007] According to the present invention, since the lubrication motor is fixed by support members connected to the left and right support columns of the housing body, the amplitude of the pump unit when transporting the lubrication device can be kept small, thereby improving safety.

[0008] In the aforementioned refueling device, by providing a front panel that covers the front of the pump unit and the flow meter, a nozzle holder provided on the front panel for hanging the refueling nozzle, and a reinforcing member arranged on the back surface of the front panel to which the nozzle holder is fixed, the force applied to the front panel when hanging the refueling nozzle on the nozzle holder can be mitigated, thereby preventing damage to the front panel.

[0009] Furthermore, by riveting the side of the reinforcing member to the side of the front panel at two points, the linear force applied to the front panel can be received across a surface, preventing the front panel from deforming into a V-shape.

[0010] In the aforementioned refueling device, a lever attached to the front panel and rotated by a key, and a stopper attached to the main housing and engaging with the lever are provided, and the stopper prevents the lever from moving upward, thereby preventing the front panel from moving upward and detaching from the main housing.

[0011] Furthermore, by engaging the lever with the stopper on the left and right sides of the main housing from the center of rotation of the lever, the stopper does not put a load on the lever when only one side of the lock is opened, thereby preventing deformation of the lever.

[0012] Furthermore, the above-mentioned refueling device comprises a rain gutter formed on the left and right sides of the main housing and in contact with the front panel, a hole formed in the lower end of the front panel, a protrusion provided at the lower end of the main housing and inserted through the hole, and a projection provided at the lower end of the front panel and in contact with the rain gutter. This prevents the lower end of the front panel from entering inside the protrusion, prevents scratches on the front surface of the front panel, and improves ease of assembly. [Effects of the Invention]

[0013] As described above, the present invention provides a refueling device with a simple configuration that minimizes the amplitude of the pump unit when transporting the refueling device, and has features such as high safety. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0015] Next, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

[0016] FIG. 1 shows an embodiment of a fuel supply device according to the present invention. This fuel supply device 1 includes a fuel supply mechanism (see FIG. 2), a display 5, a fuel supply nozzle 6, etc. inside or on the surface of a housing main body 2. A safety joint 3 at the forefront of a fuel supply pipe is arranged at the upper part of the housing main body 2, and the space between the safety joint 3 and the fuel supply nozzle 6 is connected by a fuel supply hose 7. The back side of the fuel supply device 1 is configured in the same way as above.

[0017] The housing main body 2 includes a pair of columns 21 and 22 on the left and right, and a bed 20 for fixing to an island (not shown) at the lower part with an anchor bolt or the like. It also includes a lower case 23 for housing a fuel supply system and the like, an upper case 24 for housing the display 5 above the lower case 23, and a top case 25 to which the safety joint 3 is attached and on which a pipe for connecting the fuel supply hose 7 is arranged.

[0018] The fuel supply mechanism has the same configuration and operation as those provided in a conventional fuel supply device, and is composed of a fuel supply pump 12, a fuel supply motor 13, and a flow meter 14 shown in FIG. 2, and a fuel supply hose 7, a fuel supply nozzle 6, etc. shown in FIG. 1. This fuel supply mechanism is provided with, for example, three systems of high-octane gasoline, regular gasoline, and light oil on each of the front side and the back side of the fuel supply device 1.

[0019] [[ID=2,6]] A fuel supply hose 7 (see FIG. 1) is connected to the discharge port 14a of the flow meter 14 via a pipe 27. The fuel supply nozzle 6 attached to the tip of the fuel supply hose 7 is hung on a nozzle hook 16 formed on a front panel 15 provided on the front and back surfaces of the lower case

[0020] As shown in Figures 2 and 3, inside the lower case 23, oil supply pumps 12 for supplying different oil systems are mounted on a U-shaped base plate 26, and above each oil supply pump 12, a corresponding oil supply motor 13 is positioned. The base plate 26 is attached to the bed 20. These oil supply pumps 12, oil supply motors 13, and base plate 26 are integrated and unitized as a pump unit to facilitate assembly.

[0021] A flow meter 14 is positioned above the oil supply motor 13, and this flow meter 14 is attached to a beam plate 30 that forms the upper part of the lower case 23. The discharge port of the oil supply pump 12 is connected to the inlet of the corresponding flow meter 14 via piping 28. Piping 27 is connected to the discharge port of the flow meter 14, and the other end of piping 27 is led from the lower case 23 through the left and right support columns 21 and 22 to the top case 25.

[0022] Support members 29 for fixing the oil supply motor 13 with bolts B are connected to the left and right support columns 21 and 22 via brackets 31 to 33, etc. One of the features of the present invention is the inclusion of these support members 29. By fixing the oil supply motor 13 with the support members 29, the amplitude of the pump unit when transporting the oil supply device 1 can be kept small, preventing damage to the piping 28 and increasing safety during transport.

[0023] The front panel 15 shown in Figure 1 covers the front of the pump unit and flow meter 14, and, as shown in Figure 4, is equipped with a nozzle holder 16 for hanging the fuel nozzle 6 (see Figure 1). A reinforcing member 36 is provided horizontally on the back surface of the front panel 15, and the sides of both ends of this reinforcing member 36 are fastened to the sides of the front panel 15 at two points by rivets 37 and 38.

[0024] The reinforcing member 36 reduces the force applied to the front panel 15 when the fuel nozzle 6 is placed on the nozzle holder 16, thereby preventing damage to the front panel 15. Furthermore, by riveting the front panel 15 and the reinforcing member 36 in two places, the force applied linearly to the front panel 15 can be distributed across a surface, preventing the front panel 15 from deforming into a V-shape.

[0025] As shown in Figure 1, the front panel 15 is provided with keys 40 at the left and right upper ends, respectively, which are used when attaching or detaching the front panel 15 to the lower case 23. As shown in Figure 5, the keys 40 have plate-shaped levers 41. On the other hand, the lower case 23 is provided with a stopper 42 that engages with the levers 41, and the stopper 42 has an engagement hole 42a that is narrow at the top and wide at the bottom.

[0026] When attaching the front panel 15 to the lower case 23, from the state shown in Figure 5(a), the lever 41 of the key 40 is inserted into the engagement hole 42a of the stopper 42, and as shown in Figure 5(b), the lever 41 is positioned above the engagement hole 42a, thereby preventing the lever 41 from moving upward. This prevents the front panel 15 from moving upward and coming off the lower case 23.

[0027] Furthermore, conventionally, as shown in Figure 6(a), when only one side of the lock was opened, the lever 41P would come into contact with the stopper 42P fixed to the lower case 23P, and there was a risk that the lever 41P would be bent by the stopper 42P. In the present invention, by changing the shape and mounting method of the stopper 42 as described above, there is more room for the angle in which the front panel 15 can be opened than in the conventional invention. As a result, when the lever 41 comes into contact with the stopper 42, stress is not applied to the lever 41, and deformation of the lever 41 can be prevented.

[0028] Next, the procedure for attaching the front panel 15 to the bed 20 will be explained. Figure 6 shows the conventional method, in which, when attaching the front panel 55 to the bed 20, a hole (not shown) formed in the bottom of the front panel 55 was inserted into a protrusion 51 formed in the upper part of the bed 20. At that time, the lower end 55a of the front panel 55 would enter the inside of the protrusion 51, the front surface of the front panel 55 would come into contact with the protrusion 51, the protrusion 51 would scrape the paint on the front surface of the front panel 55, and the front surface of the front panel 55 would get scratched.

[0029] Therefore, in the present invention, as shown in Figure 7, a projection 15a is provided at the lower end of the front panel 15 that protrudes toward the rear. By lowering the front panel 15 while bringing the lower end of the front panel 15 into contact with the downpipe (downpipe) 52 connected to the side of the support column 22 (and support column 21), the lower end of the front panel 15 does not get inside the protrusion 51, and the hole 15b formed in the bottom of the front panel 15 is inserted into the protrusion 51, making it easy to attach the front panel 15 to the bed 20. This prevents the protrusion 51 from scraping the paint on the design surface of the front panel 15 and damaging the design surface, thereby improving ease of assembly.
