Description

Motor vehicle filling station.

In general, motor vehicle filling stations, at least as far as they dispense liquid, are underground Storage container for the fuels, from which the fuel is pumped over fixed lines is conveyed to tapping points, in which corresponding measuring devices are provided, through which the fuel is delivered via a movable line `` These dispensers '' or gas pumps are mostly on a small island about in located in the middle of the gas station so that the driver can drive his vehicle to the Have to drive up to this island for refueling and stop close to the gas pump. Often is However, it was due to the narrow entrances and exits and because of the in the middle of the, gas station standing island with the gas pumps ':' '.' '"..''''-', *. y., .. difficult to drive the vehicle bring it close to the gas pump and exit the narrow passage again, as the access to the pumps is by vehicles, which e at the adjacent pump refueled is blocked. This is especially important when several Types of fuel are handed over to an indifferent petrol station and has the consequence that petrol pumps often remain unused.

@ In a known embodiment of a motor vehicle filling station (see DasdeutscheGebrauchsmusterl843576) the display devices for the amount of fuel dispensed are not visible for the fuel attendant and the driver, rather, they are made visible by means of a television camera. With the well-known In practice, the fixed lines are practically not up to the level of the carriageway moved out. On the side of the roadway incßdaMh: 'take-up drums for the movable ones Dispensing lines are provided, which in turn are permanently laid in the area of the carriageway level Lines are connected. The end tips are connected to the movable lines Filling nozzles are hooked into lugs specially provided for this purpose, so that the result A row of bowls is created next to each other and to the side of the carriageway. This arrangement 'also has the' disadvantage 'described, that in the case of an unfavorable arrangement' " no other vehicles are refueled by one or two vehicles at the same time can. r ,,.

Proceeding from this prior art, the invention is based on the object of a motor vehicle filling station so ~ to train that seldt taking into account d; e's'-ç 'at motor vehicle filling stations ³The usual lack of space to park several vehicles at the same time - * ' can be refueled at all designated tapping points.

The invention relates to a motor vehicle filling station for liquid. Fuels with underground storage containers and pumps for conveying the fuel from the storage containers via fixed lines, appropriate measuring devices and movable lines in the fuel tank of the vehicle to be refueled, wherein the pumps and measuring devices assigned to the individual tapping points outside of the Roadway, for example underground, the display devices for the amount of fuel dispensed also outside the lane, but clearly visible to the gas station attendant and the Drivers are arranged.

The invention consists in the fact that the permanently installed lines up to to the connection point but the roadway, for example in the roof of the motor vehicle filling station, are up and at these connection points the movable dispensing lines in the Are connected in a manner that they are not in use in a manner known per se Rolled up into a few loops and with its tap in the gas station attendant's grasp Height, but hang down without obstructing through traffic, as well as if necessary can be pulled down in the tank position.

The simplest version is designed to be close to the tap at the extreme end of the tap the lower end of a beige Yvebel or a chain is attached, which over a piece in guide rings on the movable Dispensing line along to the drum of a spring balance near the connection of the stationary is guided and fastened to the movable nozzle, through which When the drum rotates in one direction, the dispensing line becomes several loops retractable and expandable when the drum is rotated in the other direction for refueling is. In another embodiment, the movable dispensing line is close to the connection on the stationary fuel line a rotatable, spring-loaded Drum for winding the dispensing line in one direction of rotation and for unwinding in standby position, in which the dispensing line for the gas station attendant. at handle height hangs down, provided when rotating in the other direction, furthermore the dispensing line against the pressure of a spiral spring arranged in the drum for refueling Can be pulled down by hand and after the refueling process again due to the spring force in the ready position can be wound back. In particular, it is provided that the drum in one at a corresponding height but the roadway arranged housing on one part a two-part shaft mounted in the side walls of the housing is that the shaft part carrying the drum is hollow and with its bore to the stationary fuel line via a seal and to the one on the drum attached inner end of the dispensing line is connected that the two shaft parts in alignment with each other and rotatable against each other, whereby the a shaft part at the inner end carries a gear and this with a second gear combs, which on a stub axle on one on the inner end of the other shaft part seated arm is stored and one on its side face facing this arm with a stopper on the arm cooperating stop pin carries, and that one Coil spring with their end on the second shaft part and with theirs the other end is attached to a spring housing connected to the drum, whereby when the second shaft part is rotated in one direction, for example by an electric motor drives the drum over the stopper resting against the stop pin and the consequent rolling gears are also rotatable and the on her wound dispensing line can be unwound in the standby position. At a Another advantageous embodiment is the drum on which the dispensing line in Rest position can be wound up via a slip clutch with a switchable electric gate connected to the dispensing line by rotating the drum by means of the electric motor Can be developed in one direction in the standby position and with a strong pull by hand on the tap this from the standby position due to the existing Slipping clutch can be pulled down in tank position. It is provided in particular that the drum on a partially hollow one mounted in the side walls of a housing Shaft is seated, the open end of which has a corresponding seal with the stationary Line is connected, while at the other end of the bore the inner end of the short behind it is connected to the tap attached to the drum that on the inner end of this shaft with a gear on a second shaft kSmmendes Gear sits and the second shaft at its other end is one part of a slip clutch carries, whose counterpart sits at one end of a third shaft, which in turn mechanically connected to the switchable electric motor via a spindle drive is, whereby when a pull on the dispensing line from the standby position to the tank position one coupling half can be rotated without the other coupling half moving rotates, and that a selector shaft with one with the gear on the second shaft meshing gear is provided at one end, through which three Cam disks can be rotated synchronously, with which three corresponding switches assigned cam followers interact, with these cam disks and their cam followers are arranged such that when the dispensing line is pulled down by hand the standby position in the tank position, the second curve runner in the recessed part its cam rests against this and thereby the motor itself when it is closed Main switch turns off, while both when the fuel dispenser is in the tank position About the first cam with its runner, which is responsible for the full winding of the Dispensing line on the drum from the standby position controls how about the third cam with its runner, which partially winds up the tapping line controls the assigned switch from the tank position to the standby position can be closed and thus when one of the corresponding main switches is closed the dispensing line in standby position or in one go completely on the Drum can be wound.

In the following the invention is based on the exemplary embodiments only illustrative drawing explained in detail; It shows: Fig. la a spherical View of a well-known motor vehicle filling station showing the obstruction of a smooth and quick refueling thanks to the petrol pumps fixed on an island power, 1b shows the same schematic view of an inventive Motor vehicle filling station to explain the essential advantages, FIG. 2 shows another Embodiment of the invention in the same representation as Fig. La and lb, wherein the passages as well as the positions of the dispensing lines, the actuation switch and indicators are shown, FIG. 3 the motor vehicle filling station according to FIG. 2 in schematic form Representation seen from the side, Fig. 4 is a schematic side view of the invention Dispensing line in the simplest embodiment, Fig. 5 the upper part of the object according to Fig. 4 for the representation of the contracted dispensing line, Fig. 6 a schematic Section through the drum and the associated devices for winding and Unwinding the dispensing line in another embodiment, FIG. 7 is a view the mechanism that causes the nozzle shown in FIG. 6 to be aimed down from the standby position into the refueling position by hand, FIG. 8 a section of the unit consisting of the leaf stopper and the drum, the wing stopper-removably engages in one of the recesses on the circumference of the drum and for locking the drum in the tank position of the dispensing line is vague, Fig. 9 shows a schematic representation of a further exemplary embodiment and FIG. lo different Cam positions between the cams and their rotors in the mechanism according to FIG. 9.

The known motor vehicle filling station shown in Figure la has three gas pumps X, Y, Z, which are on an island in the middle of the gas station. If one now assumes that vehicles A and B are refueling from gas pumps X and Y. a vehicle C cannot get near the tapping point Z to refuel to become. In the case of the motor vehicle filling station according to the invention shown in FIG. 1b, whose area is exactly as large as the motor vehicle filling station according to FIG. la, can the car C easily reach the tap Z, while the vehicles A and B, as there is enough space to get to the tap Z, at which the dispensing line can be pulled down. As in Figures 2 and 3 schematically is shown, are at an'erfindungsgemfiæsen motor vehicle filling station, for example four flexible dispensing lines P1, P2, P3 and P4-provided, each of which leads to a Roll or individual tight loops are wound and, if necessary, high on the tap can be pulled down into the desired tank position. For each of these dispensing lines are the corresponding actuation switches S1, S2, S3 and S4 as well as indicators ID1, ID ID3 and ID4 provided.

These switches, which are designed as pressure switches, for example can be toggle their corresponding Electric motors, which drive the corresponding hose reel to wind up or unwind the dispensing line. Each of the indicators ID1, ID2, ID3 and ID4 shows the data via the lines P1, P2, P3, respectively and P4.

These indicators are electrically connected to measuring devices, which are located anywhere else without obstruction to traffic. if the switch S. is operated to bring the dispensing line P into the tank position, is the indicator ID automatically to zero in preparation for the next refueling process posed. The electrical equipment for this purpose can be known per se Manner by any skilled person depending on the requirements and should for this reason are not explained in more detail here.

In Figures 4 and 5, the simplest designs are shown. This motor vehicle filling station has a cantilevered roof 11, which extends over the lane of the motor vehicle filling station, and in which one Fixed line 16 is installed, which from the underground, not shown Fuel container is guided upwards. At the sweetest end of this fixed one Line 16 is one end of a flexible, such as a hose line 17 connected. A customary spring compensation 21 is installed in the roof 11 whose drum a flexible cable or chain 22 is wound which through one or more, at appropriate distances from one another along the hose line 17 attached guide rings 23 runs through it. Near the tap is the furthest End 24 of this chain 22 or cable to the Hose line 17 attached. As FIG. 5 shows, there are several of this hose line 17 under the spring compensation 21 Loops pulled together so that the distance from the tap to the roadway is about 2 m is. If necessary, the gas station attendant can take hold of the tap and the hose 17 pull down against the force of a spring in the balance 21 to a vehicle refuel as shown in FIG. When he releases the tap 26, The spring winds the chain 22 back onto the drum of the spring balancer 21, whereby the hose line 17 is pulled together to form several loops, which can be grasped by a hook 25 under the spring compensation 21.

In the figures 6 to 8 another embodiment is shown, which one erected over the passage or lane of the motor vehicle filling station Support frame 1o1 has.

A housing 102 hangs down from this support frame lol, in which a drum 103 is mounted on a shaft lo4a, lo4b, the shaft lo4a, lo4b is fitted on or in the housing 102 in alignment therewith, so that the Shaft lo4a, lo4b in bearings 105a and 105b in the side walls of the housing lo2 are rotatable with respect to one another. One end of the shaft lo4a can be rotated into the Outer end of a permanently installed line 106 used, which is not shown underground fuel tank up to the support frame. This wave lo4a is hollow at its end facing the fixed line 106, so that it Cavity or blind hole forms an inlet line for a hose line 107, which is wound on the drum lo3. At the junction between the permanently installed line lo6 and the rotatable inlet part of the hose line 107 is preferably a seal in shape a sealing ring 108 provided. The hole ends approximately in the middle of the shaft lo4a, where it is in a Connecting line lo9 passes over, which is connected radially to this shaft lo4a and then leads to the hose line 107, the inner end of which leads to the drum lo3 any means, such as a bracket llo is attached.

The shaft lo4b runs to the other side of the housing 102 and carries on its end protruding from the housing 102 a chain wheel lo9a, over which a chain lo9c reads, which leads to a second sprocket lo9b on the output shaft an electric motor 111 leads. Preferably somewhere in between this Motor 111 and the input shaft lo4b a spindle drive is provided when the motor 111 is switched on via the switch, not shown, it rotates the shaft lo4b counterclockwise. The shaft enters lo4a near its inner end Gear 112, which meshes with a second gear 113, which on a short Shaft 114 is rotatably mounted, which is attached to a support arm 115, which in turn is rigidly connected to the other shaft lo4b. How particularly clear shown in Figure 7, a stopper 117 is rigidly attached to this arm 115, so that it rests against a stop pin 116 on a side surface of the gear 113 can strike. Normally, this pin 116 is due to the force of the spring 12o on stopper 117, as will be described in detail below.

As a result, even if the shaft lo4b and consequently the Arm 115 is rotated counterclockwise, the gear 113 is not rotated as the pin 116 presses against the stopper 117. As a result, it rolls the Gear 113 only depends on gear 112. The rotation of this gear 113 clockwise therefore rotates the gear 112 clockwise, which in turn the shaft lo4a and thus the drum 103 stuck on this shaft lo4a in a clockwise direction twisted so that the wound hose line 107 is released. and you free end sinks to a height in which it does not obstruct the vehicles, however can be taken by the gas station attendant.

By any suitable mechanism, such as a cam with an assigned curve runner, which operates a microswitch, the motor can be switched off, so that the drum 103 when the desired height is reached the tap is stopped. An electromagnetic brake is preferred provided, which is de-energized when the engine is switched off in this way, so that after-running of the drum due to inertia is effectively eliminated. If the hose line 107 by hand against the action of the aforementioned spring is pulled down, the drum 103 is rotated further in the same direction, whereby the gear 112 rotates clockwise in FIG. However, here the arm 115 cannot be rotated, since the shaft lo4b, which carries this arm, as a result the self-locking of the spindle drive between the shaft lo4b and the motor does not can be twisted. As a result, the gear 113 must be counterclockwise in Figure 7 are rotated to the gear 112 against the force of a spring 12o to twist. In this way, the pin attached to the side of the gear 113 becomes 116 pulled by the stopper 117. Before 'this twist counterclockwise he comes Pin 116 approximately on the other side of the stop 117 if the free end, d. H. so the tap on line 107 from the standby position was brought to the petrol station. During the rotation of the drum, the coil spring becomes 12o twisted together because you have one end on the now non-rotatable shaft'lo4b and the other end on the spring housing 121 and thus on the now rotating drum 103 is attached. Therefore, when the tap on line 107 is released, the drum becomes in the opposite direction as a result of the force stored in this spring 12o Twists direction and winds the line 107 on itself. To an 'undesirable This reverse rotation is preferred to prevent coiling of the hose as a result of the spring force by engaging a wing stopper 123 in one of the Outer surface of a drum 122, which is firmly mounted on this shaft lo4b, formed Prevents depressions. The wing stopper 123 easily comes out of the recess 124 lifted out, as is well known, when line 107 is suddenly released will. However, the spring 12o only serves to bring the line 107 into the standby position wind up while when the motor 111 is turned on in the reverse direction of rotation is, the line 107 is wound up further.

The indicator showing the amount of fuel dispensed can be reset to ZERO if the line 107 begins to lower, for example by the fact that the Microswitch is provided at any suitable point of the device. As soon the display device is reset to ZERO, the motor can purely Switch on the pump system automatically so that the fuel for the next refueling process is ready as soon as the tap is opened. This one Facilities are known to every person skilled in the art and adapted to the respective circumstances no further explanation of the electrical devices is required and circuits for these and other purposes.

In the case of the prescribed versions, the one at the extreme end the line lo7 seated tap against the force of the spring, which this hose line can wind back into the standby position, pulled into the tank position.

In the further exemplary embodiment to be described below is the pulling down of the free end of the line 107 from the standby position executed in tank position by a friction clutch, which with a spindle drive, which consists of a worm and a worm wheel, and three cams with Rotors and microswitch units instead of the support arm for the gear co-operating spiral spring, which the contact of the stopper on the stopper pin on the gear in the second embodiment according to Figure 6 to 8, interacts. In this third embodiment, which is explained in FIGS. 9 and 10, the line 107 from the tank position completely again in one go by the engine wound up.

Figure 9 shows the mechanical relationships between the various elements in schematic view. Because the construction, the arrangement and the way of working of the elements other than the aforementioned are exactly the same as the previous one Execution, the illustration and explanation of these common parts is intended to Avoid unnecessary repetition.

The execution according to FIG. 9 has a drum 2o3 for winding a hose line 207, the drum 203 being fastened on a shaft 2o4, which is rotatably mounted in bearings in the side walls of the housing. on This shaft 2o4 also has a gear 212 which is connected to a second gear 213 combs, which in turn is firmly attached to a second shaft 2o4a. It should be noted that these waves 204 and 2o4a are not like waveslo4a and lo4b align with each other in the second execution. One end of the wave 2o4a is rigid. attached to one part of a friction clutch 253 while the other Part of this coupling is attached to the inner end of another shaft 2o4b, which is mechanically connected to a fourth shaft 204c, for example via a chain wheel 2o9a, a chain 2o9 and another chain wheel 2o9b. The wave 2o4c is rotated by a switchable electric motor 211 via a spindle drive 254, which a snail spindle and a worm wheel and a universal joint or the like. 255 has. Another gear 251 is provided, which with gear 213 ammt on the shaft 2o4a. This gear 251 is stuck on the Switching shaft of an electrical switch box 252, which contains three switches, who work with three cam followers FI) F2 and F3 (Fig. Lo), which on slide along corresponding cams C1, C2 and C3, these cams can be rotated synchronously by the selector shaft on which this gear 251 sits.

An explanation of the individual elements of this training except for the friction clutch 253 and the switch box 252 with its cams and the assigned curve switches C1, Fl, C2, F-2 and C3, F3 should be superfluous, since they have already been explained either in the description of the second version or can be obtained from FIG. 9 without further ado. The clutch 253 is as usual Slipping clutch formed, which the driving force from the motor 211 to the drum 2o3, but allows a mutual rotation of its two parts, if the shaft 2o4 is rotated in the opposite direction by the free The end of the line 2o7 pulled down from its standby position into the tank position will. This can be one of the two parts of this coupling together with the shaft 2o4a can be rotated without the other part of this coupling being rotated.

The cams shown in Figure lo are C1, C2 and C3 in each case provided for the rotation of the drum 203 when the motor is switched on 211 to stop, namely cI to stop the winding of the line 2o7 in the Completely wound layer P from the ready position P2, CS for stopping the reverse operation in the standby position P2 from the fully wound position P1 and C3 to stop this operation in the standby position P2 from the tank position P3.

The positions of the cams C1, C2, C3 with respect to their corresponding Curve runners F1, F2 and F3 are in the ruptured row P1 in Figure 10 for the case shown that the line 2o7 is completely wound. Like in the middle the top row can be seen, the curve runner F2 runs on the protruding one Part of the cam slide C2, the switch interacting with this cam follower closes the circuit for the motor. Therefore, if the main switch, not shown is closed, the motor starts up and releases line 2o7 so that it can can unwind in the standby position, in which your tap about 1.80 to 2 m above the ground, i.e. at a height that the gas station attendant can reach.

The positions of the cams C 11 C2 and C3 in this standby position P2 of the dispensing line 207 are shown in the middle row of FIG. In in the middle of this row you can see * that the curve runner F2 is just recessed into that Part of the cam C2 has entered from the raised part, whereby the with The switch that interacts with this curve bank is opened and, as a result, the motor is turned off.

When the tap at the extreme end of the line 207 is pulled down will be the drum and as a result all cams from the positions shown in the middle row to those in the bottom row twisted. On the right side of this bottom row you can see that the curve runner Il3 runs on the protruding part of the cam C2. Therefore, when the main switch, which can also be provided on the tap of line 2o7, closed is, the circuit for operating the motor is closed, so that this rotates in the opposite direction and winds up the hose line 2o7. When the free end or the tap on the line 207 is in the ready position arrives, cam C3 takes the one on the right side of the middle row position shown so that the line is pulled down by hand for refueling or can be completely wound up.
