Description

DETAILED DESCRIPTION OF THE INVENTION The refueling device of the present invention has a large refueling range, is easy to operate because it can be moved to the side by holding the nozzle valve and refueled as it is, and has a vertically elongated case that accommodates the hose.
A hose with less damage, a good appearance, and no risk of the hose coming into contact with the ground or other objects, i.e., a hose with one end connected to a fuel supply pipe and a nozzle valve installed at the end of the pond.
It consists of an elastic support body that supports the hose in a U-shape, and a vertically elongated case with one side open that accommodates the hose in a U-shape.

A refueling device connects a hose with a nozzle valve at the tip to a refueling pipe located 1 to 1.5 feet above the ground.The hose is wound downward, so when refueling, the hose can be moved to the side by holding the nozzle valve. This causes the inconvenience that the wound part of the hose comes into contact with the ground or the car, causing damage.Also, since it is wound downward, there is a restriction on the length of the wound part, that is, the length of the hose, which limits the ability to refuel. The range is limited and the weight of the hose is on the hand holding the nozzle valve, so
In addition, the hose is exposed and protected from wind, rain,
There are drawbacks such as severe damage to the hose when exposed to sunlight.

In addition, a refueling device in which a hose with a nozzle valve at the tip is supported upward by an elastic support increases the refueling range, but if the hose is exposed, the hose may swing due to wind or rain. Disadvantages include that the hose is easily damaged, that it deteriorates when exposed to sunlight, and that it looks bad.

The refueling device of the present invention eliminates these inconveniences and drawbacks, and includes a hose 2 in which the end of the refueling pipe 1 is closed at the upper end of a case 22 at a height of 1 to 1.5 skins above the ground surface and connected to the refueling pipe. is supported upward in a rutted U-shape by an elastic support 3 such as a dovetail spring whose lower end is fixed to the case 22, and a cover 6 is placed around the helical spring. The length of the hose is approximately the same as the height of the oil fill hole, and the nozzle hook 5 is provided at the position where the nozzle valve 4 is located in its natural state by connecting the nozzle valve 4, and the hose 2 is left open on one side. It is housed in 23.

In addition, if the upright part of the hose is made into an inverted U-shape as shown in FIG. 2 and rests behind the vertically elongated case 22,
The curvature of the U-shaped part can be increased, so there is less damage to the hose, and even if the elastic support 3 becomes weaker due to use, there is less dust from exposing the hose from the vertical case, and the hose is not exposed to wind, rain, or sunlight. It never happens.

Next, how to use the hose 2 is explained. When it is inconvenient, the elasticity of the support body 3 allows the middle part of the hose 2 to be supported upward in a U-shape and housed in a vertically elongated case 23.

When refueling, hold the nozzle valve 4 placed at the level of the car tank's oil filler port, remove it from the nozzle hook 5, and move it to the side.The inverted U-shaped portion of the hose 2 will be pulled. As shown in the chain line in Figure 2, the vertically long case 23
Since the nozzle valve 4 moves without any trouble, insert the Akebono pipe into the oil filler port and pull the trigger to fill the oil.

After refueling, remove the nozzle valve 4 from the refueling port and move it to the position of the nozzle hook 5, and the middle part of the hose 2 will return to its position due to the elasticity of the support 3, and will return to the U-shape again and become vertically long. It is housed in a case 23.

Figures 5 and 6 show a hose 7 in which a steel wire 8 is placed in a U-shape, and its lower end is fixed and supported vertically.
Figures 9 and 8 show a structure in which a plurality of steel wires are formed into an inverted U-shape inside an elastic tube 9, a hose 11 is housed inside, and the lower end is fixed and supported vertically. A part of the hose 12 is formed thickly, a steel wire 14 is embedded in the thick part 13, this is shaped like a sardine U, and the lower end is fixed and supported vertically. The figure shows a glass fiber tube 15
The hose 16 is housed inside, and its lower end is fixed and supported vertically. FIG. 13 shows an elastic tube 17
is installed vertically, the hose 18 is housed inside the swivel joint 19, and the pair of swivel joints 19 are connected to the upper end in a U-shape.
A hose 21 is connected via a hose 20, and its lower end is fixed and supported vertically.

In the refueling device of this invention, the refueling hose is elastically supported upward in a sardine U-shape, so when refueling, if you hold the nozzle valve and move it to the side, the middle of the hose will extend in a straight line, and the nozzle valve will not be affected. It can be moved, and when the nozzle valve is returned to the nozzle hook, the middle part of the hose returns to its U-shaped position by means of an elastic support, making refueling operations easy.Furthermore, since the hose is supported upward, it can be easily refueled on the ground or in ponds. There is no risk of injury due to contact with objects, and since the inverted U-shaped part can be made larger, the length of the hose can be increased.
As a result, the refueling range can be expanded.

Up to 90% of vehicles receiving refueling park their tanks with their refueling ports facing the refueling machine, and 10% park with their refueling ports facing the opposite side. The nozzle valve can be easily refueled by moving the shortest distance to the refueling port and inserting it into the refueling port. This prevents the weight of the nozzle valve and hose from being added to the hands of the oiler.

When refueling is finished, the nozzle valve can be returned to the nozzle hook by the same operation, so no effort is required.

Furthermore, if a vehicle is parked with its refueling port facing the opposite side of the refueling machine, by moving the nozzle valve, the elastic hose can be extended and refueling can be performed without any problem.

Furthermore, since the U-shaped hose is housed in a vertical case with one side open, the hose is protected from wind, rain, and wind.
It is less exposed to sunlight, prevents hose deterioration, and looks good.〇〇
