Description

TECHNICAL FIELD The present invention relates to a fueling machine in which a fueling hose is supported by a hose support.

[Prior Art] In a so-called stand-type refueling machine, the refueling hose is connected to the refueling machine at a position of about 1 to 1.5 m above the ground at the refueling station, so that the refueling hose hangs down in a U shape. For this reason, when the worker removes the oil supply nozzle that is hung on the nozzle, the weight of the oil supply hose hanging downward and the oil in the oil supply hose is applied, and it feels very heavy. Also, the refueling hose that hangs down rubs against the ground surface, so the refueling hose is easily damaged.

In order to solve these problems, the present applicant has previously disclosed an oil supply hose support device in which an oil supply hose is curved upward and elastically supported in Japanese Patent Application Laid-Open No. 52-30910. This known example will be described with reference to FIG. 4. The pipe end of the oil supply pipe 2 of the fueling machine 1 is placed at a position of about 1 to 1.5 m from the surface of the earth, and the hose 3 is bent upward and attached to the pipe end. Coil spring 4 and support tube 5 and inverted U-shaped coil spring 6
The hose 3 is supported by the hose support 7, and the end portion of the hose 3 is placed at substantially the same height as the height of the fueling hole of the tank of the automobile, and the fueling nozzle 8 is connected.

Therefore, when not in use, due to the elasticity of the hose support 7, the middle of the hose 3 is curved and supported upward.

When refueling, as shown in FIG. 4, when the refueling hole of the vehicle is away from the refueling machine 1, if the refueling nozzle 8 is held and moved to the side as it is, the hose support body 7 will bend while falling and the refueling nozzle 8 The hose support 7 moves smoothly to the oil supply hole, and the hose support 7 bears the weight of the oil supply nozzle and the oil supply hose. However, when the tank's fueling hole is located near the fueling machine 1 and the tank's fueling hole is located at a low position, the hose support 7 must be bent to force the fueling nozzle to reach the tank's fueling hole. Therefore, the lubrication operability is deteriorated and the spring 4
And 6 and the refueling hose 3 are damaged.

Other conventional techniques include, for example, JP-A-58-3099.
Japanese Patent No. 6 also discloses a fuel supply hose support device in which a fuel supply hose is curved upward and elastically supported. But,
This conventional technique has the same problem as the above-mentioned conventional technique. That is, when the oil supply hole of the vehicle tank is located near the oil supply machine and the position of the oil supply hole is low, the oil supply operability deteriorates and the coil spring and the oil supply hose are damaged.

In addition, Japanese Patent Publication No. 39-17589 and Japanese Patent Publication No. 45-3
The microfilms of Japanese Patent No. 1495 and Japanese Utility Model Application No. 53-141046 (Japanese Utility Model Application Laid-Open No. 55-57590) disclose a technique in which a hose support is made expandable and contractible. Since it is not intended to solve various problems in the case where the oil supply hole is located close to and the position of the oil supply hole is low, it is impossible to solve the above problems by these techniques.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems in the prior art, and an object of the present invention is to provide a fueling machine having good fueling operability which is not restricted by the position of a fueling hole.

[Configuration of the Invention] A fuel dispenser of the present invention is a fuel dispenser in which a fuel hose is supported by a hose support, wherein the hose support includes a lower coil spring fixed to an end of a fuel supply pipe of a fuel dispenser main body and the lower portion. An expandable telescopic tube fixed to the upper end of the spring and an inverted U-shaped upper spring attached to the upper end of the elastic tube are provided, and the upper spring is attached to the upper end of the elastic tube via a swivel joint. The expansion and contraction pipe is movably attached, and the expansion pipe is an outer pipe fixed to the inner periphery of the upper end of the lower spring, an inner pipe slidably inserted into the outer pipe from above, an outer pipe and an inner pipe. An inner pipe urging coil spring that is stretched between and urges the inner pipe in the extension direction,
A long hole is formed in the lower part of the inner pipe, and a pin protruding from the inner periphery of the upper part of the outer pipe is engaged with the long hole. It is constructed so that it can penetrate the pipe.

[Operation] According to the oil dispenser of the present invention having the above-mentioned configuration,
As a result of the inner tube being able to penetrate the outer tube within the range of the length of the long hole formed in the lower portion of the inner tube, the hose support is configured to be expandable and contractible. Therefore, when refueling at a low position near the refueling machine, when the refueling hose is pulled downward by the refueling nozzle, the inner pipe contracts against the tension of the inner pipe urging coil spring. That is, when the refueling hose is pulled downward by the refueling nozzle, the expansion tube contracts, and a part of the hose support body contracts. As a result, the hose support is prevented from being deformed into an unnatural shape, the refueling operability is improved, and damage to the hose support and the hose can be prevented.

When refueling for a low position near the refueling machine is completed, it is not necessary to pull the refueling hose downward, and the coil spring for urging the inner pipe is released from the contracted state against the tension. As a result, the coil spring for urging the inner tube expands, the inner tube is separated from the outer tube (the expandable tube is expanded), and the original state is restored.

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

In FIG. 1 and FIG. 2, the refueling machine 10 is provided with an elbow 11 of a refueling pipe at a height of about 1 to 1.5 m from the surface of the earth. It is fixed. The other end of the hose 13 extends upward and is supported by a hose support 14 fixed to the elbow 11, so that the end of the hose 13 is positioned at substantially the same height as an oil filling hole of a tank of an automobile (not shown). And the refueling nozzle 15 is connected.
The refueling machine 10 is provided with a nozzle hook 16 for storing the refueling nozzle 15 when the refueling nozzle 15 is not used. The hose support 14 includes a lower spring 17 formed of a coil spring fixed to the outer circumference of the upper end of the elbow 11, and a telescopic tube 18 fixed to the inner circumference of the upper end of the lower spring 17.
The swivel joint 19 provided at the upper end of the expandable tube 18 and an upper spring 20 formed of an inverted U-shaped coil spring fixed to the outer periphery of the swivel joint 19. It is slidably supported by.
The expansion and contraction tube 18 includes an outer tube 21 fixed to the inner periphery of the upper end of the lower spring 17, an inner tube 22 slidably inserted into the outer tube 21 from above, and an outer tube 21 and an inner tube 222. It is composed of a coil spring 23 stretched between them. Then, a pin 25 protruding from the inner periphery of the upper portion of the outer pipe 21 engages with the long hole 24 formed in the lower portion of the inner pipe 22, and the inner pipe 22 is urged by the coil spring 23 to form the long hole. Within the range of the length L of 24, the expandable tube 18 is capable of penetrating into the outer tube 21, that is, expandable.

Therefore, in operation, when the refueling nozzle 15 is not used,
The hose 13 is directed upward by the lower spring 17 of the hose support 14 and the expansion and contraction tube 18, and the middle of the hose 13 is wound and supported in an inverted U shape by the elasticity of the upper spring 20. When refueling, when the refueling hole of the vehicle is away from the refueling machine 10,
If the refueling nozzle 15 is detached from the nozzle hook 16 and moved to the side as it is, the lower spring 17 falls outward and the upper spring 20 slightly opens, like the conventional one shown in FIG. Since the support 14 bends and falls down, the refueling nozzle 15 moves smoothly to the refueling hole, so that the refueling operability is good. Further, when the oil supply hole is close to the oil supply machine 10, as shown in FIG. 3, the expansion tube 18 contracts against the tension of the spring 23 by pulling the hose 13 downward. As a result, the hose support 14 is kept in a natural inverted U-shape, so that the lubrication operability is good and the spring 2
0, 17 and hose 13 are not damaged. Since the expandable tube 18 and the upper spring 20 are connected via the swivel joint 19, the operability is good because the tube 18 can be freely rotated regardless of the direction of the oil supply hole.

〔The invention's effect〕

As described above, according to the present invention, since the hose support is configured to be expandable and contractable, it is possible to prevent the hose support from being deformed into an unnatural shape depending on the position of the oil supply hole, and as a result, the refueling operability is improved. It is good, and damage to the hose support and the hose can be prevented.
