No. 2,427,749, a connection point between an oil supply hose and an oil supply pipe is provided in a housing, and a pulley which moves up and down is provided in the housing. When the refueling hose is stored, the pulley is located below the housing, and when the refueling hose is pulled at the time of refueling, the pulley moves upward according to this, and only the amount stored in the housing Some oiling hoses are longer. Also, as seen in Japanese Patent Publication No. 54-19546, a hose reel is provided inside the housing, and the hose reel is wound around the middle of the oil supply hose and the oil supply hose is extended by the length of the winding.

[0004]

However, even if the lubricating hose is housed in the housing using a pulley, the height of the housing is limited to a position where the pulley can move. Therefore, the hose cannot be housed in the housing and sags on the island. There are inconveniences such as damage or dirty parts that are in contact. Also,
In order to wind up a long oil supply hose using only the hose reel, a large-diameter hose reel is required, and there is a disadvantage that the housing becomes large accordingly.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art, to increase the length of a fueling hose that can be housed in a housing, and to reduce the space for storing the fueling hose in the housing. To provide an oil supply hose storage mechanism that allows the oil supply hose to be smoothly fed out and wound without hindering the connection between the hose connected to the discharge side of the flow meter and the oil supply hose and the winding of the oil supply hose. is there.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a fueling hose storage mechanism in which an outlet of a fueling hose is provided at an upper part of a housing. A take-up reel guide member is provided, a swivel joint rotating side is attached to one side of the take-up reel, a square shaft guided by one guide member is attached to a fixed side of the swivel joint, and the other side of the take-up reel is mounted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a fueling hose storage mechanism of the present invention, and FIG. 2 is a longitudinal sectional side view showing an embodiment of a fueling hose storing mechanism of the present invention. As a fixed-type refueling system.

[0011] As will be understood from the general structure of the above-ground fixed oil supply device, as is well known, a housing 2 is erected on an island 1 installed on the ground and an underground oil storage tank (not shown) is provided in the housing 2. Start up the refueling pipe 3 that communicates,
An oil supply pump 4 connected to an oil supply motor (not shown) and a flow meter 6 connected to a flow rate pulse transmitter 5 are provided in the oil supply pipe 3, and an oil supply nozzle 7 is provided on the discharge side of the flow meter 6 at an end thereof. Connect the hose 8. In the figure, reference numeral 9 denotes a control device using a microcomputer or the like, which controls on / off of a refueling motor by an on / off signal from a nozzle switch 11 provided on a nozzle holder 10, and measures a refueling amount by a pulse signal from a flow rate pulse transmitter 5, This is displayed on the display 12.

In the lubricating apparatus having such a structure, a take-up reel 14 which is guided by a vertically extending guide member 13 at an opposing position and slides up and down is provided in the housing 2. One end of the take-up reel 14 is attached to the rotating side 15b of the swivel joint 15 and the fixed side of the swivel joint 15
15a is attached to a square shaft 20a guided by the guide member 13. The shaft 21 implanted at the other end of the take-up reel 14 is rotatably mounted on a square shaft 20b guided by the other guide member 13, and the inside of the spring 18 for winding up the oil supply hose is fixed to the shaft 21. The outside is fixed to a square shaft 20b via a mainspring case 19.

A hose 22 connected to the discharge side of the flow meter 6 is connected to the fixed side 15a of the swivel joint 15, and a middle of the oil supply hose 8 connected to the rotating side 15b is taken up by the take-up reel 14.
Then, it was raised upward, held substantially horizontally by guide rollers 16, and led out of the housing 2 through an outlet 17 formed in the housing 2. Note that the winding force of the mainspring 18 is formed to be greater than the force applied to the winding reel 14 when pulling up the oil supply hose 8 to pull up the lower winding reel 14.

Next, the operation will be described. At the time of non-refueling, the refueling hose 8 is moved by the winding force of the mainspring 18 to the take-up reel 14.
The take-up reel 14 is positioned at the lower end in contact with the stopper portion 13b of the guide member 13 by its own weight in a state where the take-up reel 14 is wound two to three times. In this case, since the take-up reel 14 is located below in the housing 2, the lubricating oil has a length corresponding to the difference in height between the outlet 17 formed at the top of the housing 2 and the take-up reel 14 at the lowered position. The hose 8 is drawn into the housing 2,
The sum of the retracted amount and the amount wound on the take-up reel 14 is the storage amount of the refueling hose 8.

When refueling, the refueling nozzle is
And pulling it toward the filler port of the vehicle, the pulling force is transmitted to the take-up reel 14 via the filler hose 8. In this case, the winding force of the oil supply hose 8 to the take-up reel 14 by the mainspring 18 is set to be larger than the force for pulling the oil supply hose 8 upward. The oil supply hose 8 is not fed out, and this force acts on the take-up reel 14, and the take-up reel 14 is pulled up along the guide member 13. As a result, the lubrication hose 8 is moved by the length of the take-up reel 14 sliding upward.
Is withdrawn from the outlet 17.

When the take-up reel 14 is in contact with the stopper 13a on the upper portion of the guide member 13 to prevent the take-up reel from being raised further, the pulling force of the oil supply hose 8 is directly transmitted to the oil supply hose 8 as it is. The oil supply hose 8 wound around the take-up reel 14 against the take-up force of 18 is pulled out. As described above, the lubrication hose 8 for the slide of the take-up reel 14 and the amount wound around the take-up reel 14
Is pulled out of the housing 2.

When the refueling is completed and the refueling nozzle 7 is returned to the nozzle hook 10, there is no longer any force to pull out from the outlet 17, so that the refueling hose 8 is wound around the winding reel 14 by the winding force of the mainspring 18. As it is turned, the take-up reel 14 descends to the stopper portion 13b by its own weight, and stores the oil supply hose 8 in the housing 2. The take-up reel 14 may slide upward after the oil supply hose 8 wound around the take-up reel 14 is pulled out first by weakening the force of the mainspring 18.

[0016]

As described above, the oil supply hose storage mechanism of the present invention winds the oil supply hose around the sliding reel, so that the storage amount of the oil supply hose is increased, and the storage space for the oil supply hose in the housing is also small. As a result, it is possible to reduce the size of the housing of the refueling machine and to prevent damage to the refueling hose and dirt. Further, the oil supply hose can be smoothly fed out and wound without hindering the connection between the hose connected to the discharge side of the flow meter and the oil supply hose and the winding of the oil supply hose.
