Abstract

The system consists of a moving panel (1) equal in width to the vehicle it carries, equipped with guide ramps, a rocking shutter (5) and Teflon (RTM) rollers (8) driven by a motor (9). The movement of the panel is controlled by an infra-red cell (16) which also controls the opening and closing of the garage door, and a rocking contact switch (39). Other infra-red cells (6, 7) monitor the movement of the platform, while photoelectric cells in rubber buffers detect any obstacles. The whole system is controlled by a unit (17) with microswitches and electronic timers.

Description

 The present invention relates to a remote-controlled device for storing two vehicles in a small area enclosure. This device is characterized by a plate provided with two parallel and integral ramps.

The width between the ramps is equal to that of a vehicle. I1 moves laterally by means of "Teflon" rollers (registered trademark) placed under this plate. These castors are driven by a motor remote controlled by infrared cells. The control acts on the opening of the garage door and on the motor moving the tray. The device is completed by infrared detectors and timers which manage the movement of the platform.

When the vehicle is stored it leaves enough space to store another vehicle. An infrared receiver allows the exterior, to simultaneously control the opening of the door and the movement of the tray in front of the door in order to extract the vehicle or put it away.

 Many devices are known which have been constructed for storing vehicles in car parks.

 Let us recall, for example, the elevators making it possible to install vehicles at different levels, the pivoting plates intended to avoid repeated maneuvers of the driver responsible for storing the cars, and other similar systems used in large car parks.

Generally the object of these devices is to place the vehicles in conditions such that they become accessible to the user. These installations use devices most often constructed for car parks housing a large number of vehicles.

They require building-specific infrastructure. In addition, the already expensive infrastructure requires particularly complex installations with suitable foundations.

 The object of the present invention is to obviate these drawbacks by proposing an installation adapted to an already existing garage, such as for example the garage of a pavilion owned by individuals. The originality of the invention consists in being able to store two or three vehicles in a garage whose area is equal to the floor area of the vehicle. The invention also makes it possible to control simultaneously or after time delay, the opening of the garage door, the storage of the vehicle to place another vehicle, or even the movement of the plate carrying the vehicle to take it out. All these operations do not involve any modification to the existing layout of the garage.

 The invention known as a remote-controlled vehicle storage device in a small area enclosure is characterized in that it comprises a plate provided with guide, remote-controlled tilting flaps, rollers of material known by the name of "Teflon" (registered trademark ), motors with its drive, infrared transmitters and receivers, deflectors, a micromotor whose rotation is reversed by means of cams for movement displacement detectors, safety pushbuttons controlling the time delay, approach photocells, programmable timer, control cabinet, safety sensors, microswitches.

 Thus characterized, the present invention will be better understood thanks to the appended drawings which are presented for information only in a preferred embodiment, in particular in the general organization of the device.

 Figure 10 of the board 7/7 shows the electrical diagram installed in the control cabinet which has the function of calling the tray when you want to get out or put the vehicle away.

 In Figure 1 we have drawn the entire layout of the garage which, in the example, accommodates two cars. The garage is limited by four partitions (20) limiting a rectangular area equal to the floor area of two vehicles. It is closed by a remote-controlled tilting door (21). An infrared transmitter excites the photoelectric cell (16) which controls the opening of this door.

The control cabinet (17) under the action of the pulse of the photocell (16), actuates the opening or closing movement of the door and the supply of the motor (9) driving the plate (1).

Inside the garage, there is a rolling platform (1) whose width is equal to that of a vehicle. This plate mounted on "Teflon" (registered trademark) casters (8) moves from left to right and vice versa according to the geometry of the garage. The "Teflon" (registered trademark) rollers (8) are driven by a mechanism (10) constituted by a set of metal toothed pinions. This mechanism is driven by the electric motor (9) connected to the control cabinet (17). Its operation is remote controlled by means of photoelectric cells (36) arranged either on the plate (1) or on the walls (18) (19), probes (22)
stop pushbuttons (40) of the timing circuit (4). When the plate (1) is brought in front of the garage door, its movement is delayed by a motorized mechanism (4) programmed by a set of cams. These act on relay switches at level (3). The start of the timer programming is triggered by the tilting switch (39) fixed to the plate and connected to the control cabinet (17). This tilting contactor is triggered when the plate (1) moves from right to left, causing friction by tilting its arm when it meets the stop device (38) fixed to the wall. This movement creates an electrical impulse at the level of the control cabinet which triggers the start of the time delay.

The tray (1) is equipped at the rear with rocking shutters (5) remote-controlled by the infrared cells. These rocking shutters are raised when the platform is stationary, they tilt when it is placed in front of the garage door to receive or deliver the vehicle
The tray is lined on these sides with a push button (40) which short-circuits the electrical supply to the drive motor (9) when said tray touches the wall (20). Rubber tubes (22), called feelers, also line these sides. These tubes (22) carry at their end a transmitter (6) and an infrared receiver (7) connected by two conductive cables. If, during the movement of the plate (1) the latter encounters an obstacle on the ground, these rubber tubes or feelers (22) are deformed. The electrical circuit connecting the receiver (6) and the infrared transmitter (7) is broken. The absence of a pulse to the control cabinet (17) stops the electrical supply to the motor (9) driving the plate.

 At the exit of the garage, a photoelectric cell (15) which emits infrared radiation on the deflector (13). When a vehicle enters or leaves the radiation is cut off. This cut is transmitted in the form of an electrical pulse to the control cabinet (17) to manage the timing and movement of the plate.

 Manual remote controls (11) and (12) fixed to the wall are connected to the control cabinet (17). They allow the movement of the plate (1) to be interrupted.

 The control cabinet (17) and the timing management can advantageously be replaced by an electronic controller which receives the information from all the cells. This electronic controller replaces it with the control cabinet (17) and on the basis of information from the control cells a frequency converter. The latter acts directly on the electronic power supply to the motor (9) to move the rolling platform (1).

 FIG. 2 shows the cam device installed at level (3) and (4) of the general installation with the photoelectric detection cells.

 The stepping motor (23) is supplied by a voltage of 24 volts taken from the control cabinet (17). Its movement drives the cams (26) and (25) by means of belt (32). These cams are responsible for timing.

All of the micromotor power supply driving the cams, as well as the photoelectric cells of the timing circuit are connected to the control cabinet (17) and by means of the terminal block (30). The stepping motor (23) has a low voltage power supply controlled by a series of microswitch type switches (27) (28). The powered stepper motor (23) drives the cams (26) and (25). The reversal of the direction of rotation of the motor is caused when the photocells (16) or (36) are energized. A general circuit breaker (29) protects this installation in the event of an anomaly
When the plate (1) moves to the left, the arm of the tilting contactor (39) strikes the angle device. driving the cam (26) and constituting the timing mechanism. This cam (Index 4 in FIG. 1) will make a rotation for about two hours keeping the switch closed (24) so as to power the rotation of the motor (23).

 When this cam (26) returns to its starting position, its stop (31) depresses the push button of the switch (24) and interrupts the supply of the motor (9) by means of the control cabinet ( 17).

 The speed of rotation of the cam (26) is a function of the delay time.

 Conversely, the cam (25) has not rotated and maintains the position of the switch (34) engaged at level (32) so that the stepping motor (23) remains energized. If the photoelectric cell (16) for controlling the opening of the garage door is excited, the cam (25) driven by the motor (23) will rotate for a certain duration. This time is necessary to ensure the movement of the plate (1) by the motor (9). The movement allows it to be positioned in front of the garage door to exit or load the vehicle on the platform.

 These same operations can be controlled by manual controls (11) and (12) fixed to the wall acting on the electrical supply of the device.

 There are shown in Figures 3, 4, 5, 6, of the board 3/6 different connections of the photoelectric cells used for the proper functioning of the entire device.

 In FIG. 3, the photoelectric cell (15) fixed to the wall at the front door emits radiation reflected at level (13). When the door cannot be closed, the infrared radiation from the photoelectric cell (15) is cut, emitting a perceived pulse across the terminals of the control cabinet (17). This interrupts the power supply used to operate the door.

Manual controls (35) are provided inside the garage to rearm the infrared device after the obstacle has been eliminated in front of the door.

 In Figure 4 of plate 3/7 we have drawn the safety device (22) mounted on the sides of the plate (1). This security controls the stopping of the motor (9) when an obstacle arises during the movement of the carriage.

 At each end of the rubber tube (22) an infrared transmitter (7) has been connected which is connected to a receiver (6) by means of conductive cables (37). These cables are embedded in these rubber tubes (22) called probes. When an obstacle arises, the cable connection between the infrared emitter (7) and the receiver (6) is broken. The photoelectric cell (36) is no longer supplied by the transmitter (7) and receiver (6) circuit.

 This break in transmission is perceived by the photoelectric cell (19) which is connected to the control cabinet (17) which interrupts the electrical supply to the drive motor (9) of the plate.

 FIGS. 5 and 6 show the connection of the cells (6) and (7) constituting the complement of the security system described above.

 The connection of the infrared emitters (7) and the receiver (6) is supplied with a voltage of 24 volts via the control cabinet (17). Figure 5 shows the device in operation. The transmitter (7) and the infrared receiver (6) cause the device to stop completely when the photoelectric cell (19) is no longer energized interrupting the power supply to the drive motor (9) at the control cabinet (17).

FIG. 7 shows the electric timing circuit controlled by the opening of the garage door. The entire circuit is connected to the control cabinet (17). When the door (21) opens it acts on two microswitch (42) (43) which provides an electrical impulse to the remote control switch (46) by acting on the load capacity (47)
The load capacity (47) connected to the electronic timing circuit (40) emits after a determined time an electrical pulse which controls the reversing switch (48). When the delay time has elapsed, the deactivated photocell (45) cuts off the power supply. Closing the door causes the opposite phenomenon until the microswitches (42) (43) interrupt the electrical supply to the plate (1). The manual switch (44) allows to interrupt the timer program which acts on the door opening or closing mechanism.

 There is shown in Figure 8 the diagram of the device triggering the fixed rocker switch on the wall of the garage indexed (38) on the board 1/7.

 This device consists of a brass angle (38) which pivots by an angle of 900 from point B to point A.

 This angle (38) is fixed to the wall (20) by means of a hinge (50) constituting a hinge. Point B of the angle iron is connected to the return spring (52) by means of a steel cable (54) which slides on two pulleys (53) fixed in the wall. The rubber stopper (51) allows the movement of the angle iron (38) to be damped when it returns to its central position (B) under the action of the return spring (52). This rubber stopper is located in height outside the fields of development of the plate.

 FIG. 9 of the board 6/7 shows the device of the indexed rocker switch (39) on the board 1/7. The rocker switch (39) is pivotable.

During the movement of the carriage, the contactor will meet the swivel brass angle (38) fixed to the wall. At this time the contactor (39) tilts, triggering an electrical pulse at the electronic relay (60). This pulse is transmitted to the control cabinet (17) by means of the connection box (61).

 The electrical pulse will trigger the timing mechanism described in Figure 2. When the rocker switch (39) exceeds the angles (38) it returns to its original position. The brass angle (38) resumes its function by means of the return spring (52). The metal axis (50), the slide (62) and the plastic frame (64) fix the angle (38) and keep it horizontal during its movement.

 Is shown in Figure 10 of the board 7/7 the electronic diagram intended to call the tray (1) when the photoelectric cell (16) perceives an infrared emission which controls the opening of the garage door (21) .

 The circuit is supplied with 220 V. at level (71) of the terminal block (30). This supply can be cut manually by means of the switch (68). The 220 V power supply is connected to the transformer (66) via the terminal block (30) and the control cabinet (17).

 This transformer provides electrical power at 220 v. the general timer (67) connected to the remote control switch (70). The timer (69) supplied with 24 V. connected to the photoelectric cell (73). This photoelectric cell is contiguous with the photoelectric cell (16). The microswitches or switches (72) are actuated by the movement of the plate (1) when the latter is placed in front of the garage door. This microswitch (72) causes an impulse at the level of the control cabinet (17) which triggers the remote control switch (70) to stop the supply of the motor (9) of the plate (1).
