[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable refueling device mounted on, for example, a cargo bed of an automobile, and more particularly to a door structure of a housing of a refueling machine.

[0002]

2. Description of the Related Art For example, as a device for delivering kerosene or the like to each home, there is a refueling device mounted on a car carrier. Such a lubricating device houses a lubricating mechanism such as a lubricating pump and a lubricating motor, a display, and a hose reel for winding a lubricating hose in a housing, and a front surface of the housing is provided with an opening so that the lubricating hose can be easily pulled out. It is formed.
In order to prevent mischief and protect the oil supply mechanism from sunlight, wind and rain, a door is attached to this opening so as to be freely opened and closed.

Conventionally, as this door mounting / closing structure, for example, a rod-shaped stopper used for a hood of an automobile by, for example, rotatably supporting an upper end of a door to a housing and pulling a lower end of the door upward from a near side. It is locked in the open position by the above.

[0004]

In such a door opening / closing structure, an operation for locking the door to the stopper is separately required, so that the workability is not good, and the opened door is located at the upper part of the housing, that is, the work. Will be located above the members,
It can get in the way.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fueling apparatus which solves the above-mentioned disadvantages of the prior art, can easily open and close the door with one touch, has good workability, and does not hinder the door when the door is opened.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a fueling apparatus in which a front surface of a housing of a fueling machine is formed in an opening and a door which can be opened and closed is provided in the opening. A lateral groove-shaped guide rail is provided in the upper part of the inner wall in the front-rear direction, and an arm mounting part having a support hole near the opening below the guide rail is provided. Along with a roller to be engaged, a protrusion serving as an arm insertion portion is provided below the roller, and the other end of the arm rotatably attached to the arm attachment portion is rotatably inserted into the arm insertion portion, The gist of the present invention is to provide a stopper at a position where the roller is moved beyond a position where the door is opened and the arm insertion portion has moved directly above the arm mounting portion.

[0007]

According to the present invention, the door can be opened by pushing the lower end of the door upward from the front and pushing it into the housing.
While the roller slides rearward along the guide rail, the arm insertion unit rotates together with the door via the arm while drawing an arc-shaped trajectory around the arm attachment unit. Further, the stopper prevents further movement at a position slightly lower than the uppermost point of the arc-shaped trajectory, so that the door is automatically locked to the housing at this position.

When the door is closed, if the door is turned downward while pulling out the door in the reverse operation, the arm insertion portion passes through the uppermost point of the arc-shaped trajectory by the pulling force. Is naturally released and closed. Since the door moves back and forth along the guide rail while rotating, the door does not protrude greatly in front of the opening when the door is opened and closed, and the space required for opening and closing the door is small. Further, since the guide rail and the arm are provided on both side surfaces, the guide rail and the arm can be supported by a large door.

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 longitudinal sectional side view showing an embodiment of a fueling device of the present invention, and FIG. 2 is a partially cutaway front view of the same. FIG.

The fueling device of the present invention is mounted on a carrier 2 of an automobile 1 such as a truck, for example, to deliver fuel such as kerosene to each household, and is connected to an oil storage tank 3 mounted on the carrier 2. 4 is led out into the housing 5 of the refueling machine. An oil supply pump 6 and a flow meter 7 are sequentially provided in the housing 5 in the middle of the oil supply pipe 4.

The tip of the oil supply pipe 4 was connected to an oil supply hose 8 wound around a hose reel 10. Further, a nozzle hook 11 for hooking the refueling nozzle 9 is formed outside the housing 5.

A front surface of the housing 5 is formed in the opening 12,
A partition wall 13 is erected behind the opening 12. The partition wall 13 is formed at a height that does not reach the ceiling surface in the housing 5 so that a space 14 exists between the partition wall 13 and the ceiling surface, and a notch portion is provided at a location corresponding to the hose reel 10. It is formed in the opening 15 for drawing out the refueling hose 8. Further, a guide roller 16 for smoothing the drawing of the oil supply hose 8 is arranged on the periphery of the drawing opening 15.

A display 17 for displaying refueling data such as the amount of refueling, a keyboard 18 for input, an operation switch 19 and the like are provided on the partition wall 13.

In the lubricating apparatus having such a configuration, as shown in FIG. 3, a lateral groove-shaped guide rail 20 is provided in the space 14 and near the opening 12 on both inner side walls of the housing 5. An arm mounting portion 21 having a support hole near the opening 12 is provided below the opening. Guide rail 20
Stoppers 20a and 20b are formed at the front and rear ends of the.

In the figure, reference numeral 22 denotes a door for closing the upper part of the opening 12. A roller 23 for engaging with the guide rail 20 is provided on the upper side of the door 22. A protruding piece serving as the portion 24 is protruded, one end of the arm 25 is rotatably attached to the arm mounting portion 21, and the other end of the arm 25 is rotatably inserted into the arm insertion portion 24.

In the figure, reference numeral 26 denotes a lock provided inside the lower portion of the door 22, and reference numeral 27 denotes a locking piece for locking the lock, which is provided on the housing 5 side.

Next, usage and operation will be described. When the refueling device is not used, the door 22 is brought into contact with the roller 23 in contact with the stopper 20b at the front end of the guide rail 20, as shown in FIG.
Is suspended from the guide rail 20 by its own weight via the roller 23, and closes the upper part of the opening 12. In this case, the opening
Since the lower part of 12 is not closed by the door 22, it does not hinder the oil supply hose 8 which is constantly drawn from the hose reel 10 to the position of the nozzle hook 11.

Even if the door 22 is closed by its own weight, since the lock 26 is locked to the locking piece 27 at the lower part, even if vibrations and the like due to the running of the automobile 1 are transmitted to the door 22, it does not swing. Absent.

In order to open the door 22 at the time of refueling, first, the lock 26 is pivoted to be released from the locking piece 27 to release the locking, and the lower portion of the door 22 is held by hand, as shown by a chain line in FIG. This is turned upward from the front. With the upward rotation of the door 22, the arm insertion portion 24 integrally attached to the door 22 also rotates upward while drawing an arc-shaped trajectory, and the arm 25 moves around the arm attachment portion 21 as the door 22. And is pivoted upward as if pulled.

When the door 22 is pushed upward while being lifted, the roller 23 moves rearward along the guide rail 20 (see FIG. 4). When the arm insertion portion 24 is positioned on a vertical line of the arm mounting portion 21, the door 22 is pushed up to the highest position by the arm 25, and if the door 22 is further pushed in after passing through the highest point position, the door 22 is slightly At the lowered position, the roller 23 comes into contact with the stopper 20a as shown in FIG. 5, preventing further movement, and is locked at this position.

In this locked position, since the door 22 is at a position lower than the uppermost point as described above, it is not possible to stop at this position and move to the front unless a special force is applied to the door 22. Absent. Therefore, the door 22 is kept open as it is,
Further, since most of the door 22 is housed inside the housing 5, it does not hinder the work. Further, since the door 22 forms an eave on the upper side, it is possible to prevent rainwater or the like from being blown or the indicator from being viewed by direct sunlight.

In this state, the refueling nozzle 9 is detached from the nozzle hook 11, and the refueling hose 8 is drawn out from the hose reel 10.
The fuel pump 6 is driven to supply kerosene in the oil storage tank 3 to a kerosene container or the like. The refueling amount is measured by the flow meter 7 and displayed on the display 17.

When refueling is completed and the door 22 is closed, the roller 22 can be closed by pulling the front end of the door 22 forward as opposed to the above-described opening operation.
The arm 25 moves forward along the guide rail 20, and the arm insertion part 24 also moves forward along with this, so that the arm 25
Rotates forward about the arm mounting portion 21.

In this case, it is necessary to apply some force to the door 22 so as to move it upward while moving upward, until the arm insertion portion 24 reaches the uppermost point of the arc-shaped trajectory. After passing, the lock is released naturally, and after passing the uppermost point, the arm 25 rotates due to the weight of the door 22, and the door 22
22 moves in the closing direction. Instead of the stopper 20a, a stopper 28 may be provided so that the arm 25 is engaged at a position slightly lower than the vertical line as shown in FIG.

Although the above-described embodiment has been described as a portable lubricating apparatus, the present invention can be similarly applied to a lubricating apparatus which is fixedly installed on the site of a gas station and which has a door.

[0026]

As described above, the lubricating apparatus of the present invention
When the door is opened and closed manually, it can be pushed into or pulled out of the housing while rotating the door, so it can be easily opened with one touch, without any special operation. And the workability is good, and when the door is opened, the door does not protrude greatly in front of the opening and does not become an obstacle.
