Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a holding device for a refueling nozzle in a refueling system.

At a gas station, for example, a raised area (so-called island) with a flat upper surface of a certain width is set up on the ground surface, and a refueling machine is installed on top of it, so that cars parked on both sides of the long side of the island can be refueled. In order to achieve this, a single refueling machine usually has two refueling systems, each containing a nozzle and a hose.

In such a refueling machine, there is one refueling amount display on each side of the refueling machine corresponding to both long sides of the island.
We have already proposed a device that is equipped with a refueling hose for refueling, and when the hose is pulled toward either of the long sides of the 1% island, the display on that side returns to zero, making it possible to display the display. By the way.

The present invention provides a refueling nozzle holding device that can be suitably used to control the refueling system and display of the refueling device as described above.

A first aspect of the present invention is a refueling device having a retaining mechanism for retaining a refueling nozzle when refueling is not performed, in which the nozzle is detached from the retaining mechanism in an operating direction that is different from the operating direction in which the refueling nozzle is engaged to the retaining mechanism. It is characterized by being configured to allow

A second invention is a refueling device having a holding mechanism that engages and holds a refueling nozzle when not refueling, wherein the nozzle may be held l1w in at least two operating directions different from an operating direction that engages the refueling nozzle to the holding mechanism. The nozzle is characterized in that it also includes means for detecting the direction of the nozzle's detachment operation and generating a corresponding signal.

The illustrated embodiment will be described in detail below.

In Figure #11, 1 is an island raised on the ground surface G of Kanyuori, 2 is a refueling machine housing installed on the top of the island, and 5 is a wing on one side of both long sides of the island ¥1 on the top of housing 2. A similar oil supply amount display I13 is also arranged toward the other long side.

No. 4B is the underground oil storage tank (it is the oil pumping pipe on the display side, 5m and 51 are the pumps inserted into the pumping pipes 4m and 4'm, respectively).
``FB pumps 4 m, 4B pumps 5 m, 5
Flowmeters inserted on the secondary side of 1, 8mu and 8B are respectively flow meter tsums, transmitters that transmit enemy flow rate pulses corresponding to the measured flow rate of 7B, 9mu and 91 are refueling truck-su, 1
0m and loB are the oil supply nozzles. 4 pump pipes, 5 pumps, 7 flow needles, 9 fuel hoses, and 10 fuel nozzles constitute one oil supply system. Similarly, 41.51% 71%
911% 10M constitutes the oil supply system.

11m s 11m is a nozzle case arranged at the ends a12/m and 21B of both short sides of the island 10 in the upper part of the housing 2, and is a nozzle holder attached to the tip pipe of the refueling nozzle, and in the illustrated embodiment, the nozzle case 11mu,
111 and the corresponding nozzle holders 12 and 121 form a nozzle holding mechanism 13 and 13 m1, details of which will be described later.

Reference numeral 18 denotes a control unit which controls the display and the pump unit in accordance with the engagement of the nozzle with the 7th order holding mechanism or the disengagement therefrom in various S* or operating directions, as will be described later.

The second gI shows details of a simple embodiment of the nozzle holding mechanism. Since the nozzle holding mechanisms 13 and 131 are the same, they will be explained in common, and the suffix 1 will not be added to the reference numeral 1. The same applies to the refueling nozzle.

In the embodiments shown in Figures 2 to 7, the nozzle holder 12 is operated as follows. In other words, 14 is Howling Mercenary Il
! A bearing member fixed at 2' and having a through hole 14a, 15 a rotating shaft pivotally supported in the through hole 14a, 16 a swinging piece fixed within the shaft 11C and the housing 21, and lf at 1115. Howling 2 fixed outside support quartet,
16a is a radially protruding arm integral with the swinging piece 16, 19
Between the outer end of the arm 16a and the inner surface of the housing 112', a tension spring tensions the arm 16a so that the arm 16a is always at a position directly above (4111)
In this state, the support block F has grooves 17 and
It runs in a positional relationship with the swinging piece 16 so that it is held at an upper position in the -1 direction, and is identified to the rotation shaft 15.

The groove 17a is bored to the outer end (the right end in FIG. 2) of the pretquef. 21 is a detent spring whose one end 21a is screwed and fixed to the outer end surface of Block F with a screw 22#c, and the other end 21b is bent and inserted into the groove 17a (to the left in the figure). 0 10a is a protective frame for the lever 10b of the refueling nozzle 10, 10
0 is an engagement hole drilled in the rear side of the protective frame 10a of the oil supply nozzle (1 & - the bottom side of the protective frame 10a when the oil nozzle is held in an upright position with the cylinder tip facing upward as shown in FIG. 2). It is a protrusion.

As described above, while holding the refueling nozzle 10 in an upright position, insert the tip of one nozzle into the nozzle case 11, and use the protrusion 10c of the nozzle lever protection frame 10& to push the tip 21b of the leaf spring 21 of the support block 1f. The refueling nozzle is engaged with the holder 1113 by passing through it while tightening it and fitting the protrusion 10o into the groove 17a.

Even if an attempt is made to remove the nozzle from this locked state using the weight t in the upright state (toward the right in the figure), the tip 21b of the detent spring 21 hits the protrusion 10o, making it impossible to remove the nozzle.

Note that 23 is a motor control switch attached to the bottom of the nozzle nurse 11, and its operating spring piece 23& is inserted into the nozzle case from the hole 11a on the bottom of the nozzle case 11. The switch 23 is actuated by pushing the sharpening spring piece 23a inserted into the pump, and the control unit 18 performs a predetermined operation, for example, deenergizes the pump starter 8, in response to the signal. When the nozzle is separated from the holding mechanism and the nozzle tip is removed from the nozzle case 11 as described later, the operating spring piece 23a and the switch 2
3 returns and the control unit 18 starts the desired operation, for example, the motor 6.

K for separating the nozzle 10 from the nozzle holding mechanism 13 is:
The nozzle is inserted into the nozzle case 11 from the above-mentioned fixed upright state, and the 6th Wi, '71st! Slightly rotate it in either direction (clockwise or counterclockwise). That is, the end 112' of the refueling machine howling 2
When refueling a car parked on the right (R) side of island 1, move the refueling nozzle to the right (R) side as shown in Figure 6.
When refueling a car parked to the left (-), 1 rotates slightly to the left (clockwise) as shown in Figure 1. In this case, 1, the support pushpiece 17 is moved to the right (clockwise) in the case of the former (Fig. 6) with the shaft 15 centered by the engagement between the protrusion 10o of the lever protection frame 10a of the nozzle and the groove 1fa. In the latter case (Fig. 7), it tilts to the left (counterclockwise).

Due to this movement, the rocking piece 16 fixed to the shaft 15 and therefore its protruding arm 16a are also supported and pulled. 7, the projecting arm 16a is actuated by selectively contacting the switch 24N or 24L provided on both sides of the protruding arm 16a, and the control unit activates the corresponding switch in response to a signal from the actuated switch. Display @ Return 3R or 3L to zero and prepare for refueling on that side. By rotating the nozzle and tilting the support pull 1f, the nozzle can be removed from the holding mechanism 13 without the protrusion 10o of the nozzle being disturbed by the support pull 1°.

In addition, 14 east and 141 are the protruding arms 16a of the swinging piece 16.
This stopper is used to prevent damage to the switches 24B and 24L due to excessive rotation.

As described above, the protrusion 10o is connected to the groove 1 of the support pull 1f.
As a result of the barbs 19 being disengaged from 7a, the swinging piece 16 and therefore the support pull 1f are returned to the upright position.

In short, either end w12 of the refueling machine housing
/, by rotating the refueling nozzle toward the side where the car stopped for refueling among both sides of the refueling machine howling and separating it from the holding mechanism, the display on that side returns to zero and the pump motor is turned off. It can be energized and refueled.

In this embodiment, the support block 27 is the refueling machine housing 2.
0111112' K remains constant.

The groove 27a on the upper surface of the support block 2f exists only in the part where the bent end 21b of the pulley 21 returns from the outer end face of the pull 27, and the inner part is located on both sides 1 of the groove.
Notches 27N and 27L are provided by cutting out 12 hood b, and a shallow depression 2 0 is provided on the bottom surface.

Furthermore, reed switches 2B are placed on the bottoms of the notches 2F λ and 2F L on both sides! L, 28L t-111 installed. 29 is an iron piece buried in the recess 2F0, and 10d is a magnet buried in the outer end surface of the protrusion 10o of the lever protection frame of the nozzle.

No. 811, the protrusion 100 presses and bends the bent end 21b of the spring 21 for preventing return, and the depression 270 of the support pull 2 is formed.
This shows the state in which it is fitted. In this state, the tip of the nozzle is inserted into the nozzle case 11 and held in an upright state. The magnet 10d of the protrusion 10o attracts the iron piece 29 of (recess 2)0 to prevent the nozzle from moving laterally due to inadvertent contact with the nozzle or hose, and forms a closed magnetic path to connect the leads on both sides. Switch 281% Prevents the operation of 28L.

To remove the nozzle, lift it up.

It corresponds to s514TJ and performs the same function.

Although the present invention has been described in detail above, it goes without saying that the present invention is not limited thereto. For example, the shapes of the nozzle case and the support splitter can be changed as appropriate. It is not necessary to hold the nozzle in the upright position of the carp; it may be held horizontally or diagonally. Further, the support splitter is not necessarily necessary, and the nozzle may be held by supporting the nozzle tip or other parts by gripping, wire, or other methods.

A means for detecting left and right rotation of the nozzle may also be provided at a location other than the support plate or its vicinity. Also, switch 241C1s ji! 4! l (28L
