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.
Not only does the hose cause less damage, it looks good, and there is no risk of the hose coming into contact with the ground or other objects, but it also has a case protection member that prevents damage to not only the case but also the hose. A hose that is connected to a fuel supply pipe and has a nozzle valve at the other end, an elastic support that supports this hose in an inverted U shape, and an elastic support that supports the hose in an inverted U shape.
A refueling device comprising a vertically elongated case with one side open and accommodated in a letter-shaped state, in which a case protection member is provided on the open surface of the vertically elongated case.

A refueling device in which a hose with a nozzle valve at the tip is supported in an inverted U-shape by an elastic support has a wider refueling range, but if the hose is exposed, it may swing due to wind or rain. The hose is easily damaged, and furthermore, the hose deteriorates when exposed to sunlight and looks bad, and even if a case is provided, the case comes into contact with the elastic support, damaging the case and making it look bad.

This invention solves the above-mentioned inconvenience, and if we explain the drawing, the pipe end of the fuel supply pipe 1 is placed at a position of 1 to 1.5 m from the ground surface, and the base of the hose 2 is directed upward and is wound upward to provide elasticity. A helical spring 3 serving as a support body is wrapped around the hose 2 for elastic support, the hanging end of the hose 2 is placed at approximately the same height as the oil fill hole of an automobile tank, and a nozzle valve 4 is connected.

In the Kuzumaki spring 3, a spring 10 of medium elasticity is wound tightly around the base of the hose 2 and loosely around the top, and a spring 11 of lower elasticity than the upper end of the spring 10 is wound around the hose 2 in an inverted U shape. A strong spring 12 is wrapped around the outside of the tight part of the spring 10. Then, the base portion is fixed with bolts 13. In order to vary the elasticity of each part of the dovetail spring 3, springs with different elasticities may be used. The hose 2 is covered with a vertically elongated case 6 with an open front □, and rollers 7, which are case protection members, are installed along both sides of the hanging portion of the hose 2.
8 is provided, when the hose 2 is pulled out, the side of the hose 2 comes into contact with the roller 7 or 8, which rotates and does not generate much friction, making it easy to pull out and preventing damage to the hose 2 or the helical spring 3. The vertically long case 6 will not be damaged due to friction with the dovetail spring 3.

Next, let me explain how to use it. When it is inconvenient, the middle part of the hose 2 is wound upward and supported by the elasticity of the coiled spring 3.

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 state shown by the dotted line A in Fig. 2 is reached, and the nozzle valve 4 moves without any problem, so after inserting the fly tube into the oil filler port, the trigger is pulled to supply oil.

When refueling is finished, the nozzle valve 4 is removed from the refueling port and moved to the position of the nozzle hook 5, and the middle part of the hose 2 is returned to its position by the elasticity of the helical spring 3, returning to its upwardly wound shape. do.

By the way, since the elasticity of the helical spring 3 is greater near the base of the hose 2, the hose 2 does not bend from the base due to the weight of the upper part, and the elasticity is reduced closer to the top. Therefore, a small force is sufficient when pulling the hose 2.

In the refueling device of this invention, the refueling hose is elastically supported upward in an inverted 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 open. It can be moved without any trouble, and when the nozzle valve is returned to the nozzle hook, the middle part of the hose is restored to its U-shape by an elastic support, making refueling operations easy. There is no risk of damage due to contact with or other objects, and since the U-shaped part can be made larger, the length of the hose can be increased.
As a result, the refueling range can be expanded.

And since the hose is housed in a vertically long case with one side open, the hose is shaped like a sardine U.
Less exposure to sunlight, prevents hose deterioration,
It also looks good.

In addition, a case protection part is provided on the open surface, so not only the case but also the hose and the elastic support will not be damaged.In particular, it can buffer the impact to the case caused by the repositioning force due to the elasticity of the elastic support when the hose is stored. It is.

It is a diagram.
