Description

The present invention relates to a retractable terminal for reserve access, in particular to a parking space or a passage any.

The same type of terminals that are currently on the market have installation difficulties, especially in parking areas existing because they require significant civil engineering. These structures depend on an external energy source, electric or pneumatic, which causes connection problems with digging trenches. The corresponding work is sometimes long and delicate; moreover they have well often resulting in deterioration of the immediate environment.

This type of terminal is for example described in the documents FR-A-2 722 216, US-A-5 476 338 or also EP-A-0 597 543; because of their design, these terminals have a high cost price to which must be added the costs installation.

Document DE-A-3 514 626 describes a retractable bollard subjected to the action of an electric motor to ensure its extraction from the well by vertical translation or its withdrawal inside the well. The electric motor engages a rack arranged on the side of the terminal: it is associated with remote control means and it is supplied by a battery whose charge is provided by solar energy, by means of photovoltaic cells arranged on the side.
Given the structure and positioning of its constituent elements, this terminal cannot function properly.

The present invention provides a retractable bollard at a cost of relatively low installed cost, the simple design of which limits the user fees, including maintenance.

This retractable terminal for reserving access to a parking lot or the like, arranged in a well, is made up of an erectile body closed at the top, disposed in said well and subjected to the action of an electric motorization to ensure its extraction outside. of the well by vertical translation or its withdrawal inside the well; this terminal also comprises - intrinsic means of energy production which consist of one or more photovoltaic cells ensuring, from solar energy, the charging of a battery connected to said motorization, and - control means to distance from said motorization, of the transmitter / receiver type.
According to the invention, a receptacle is arranged on the upper part of the erectile hollow body, for housing the photovoltaic cell or cells covered by a transparent protective plate, the dimensions and shapes of said erectile body being adapted to penetrate said well. receiving bounded by a ferrule, on the upper edge of which is positioned a seal which bears on the periphery of the outer surface of said erectile body. On the other hand, all of the energy control and management means, that is to say in particular the electric motorization, the battery and the receiver of the remote control means, are housed in the defined tight volume. by said ferrule, in the size of said erectile body.

According to another characteristic, the terminal includes an electronic card adapted to manage the work of the electric motor. This card is powered by the battery which is connected to the photovoltaic cells, and it is placed at the interface between the receiver of the remote control means and said motorization.

According to another particular feature, the retractable bollard includes a cap terminal which projects laterally beyond the size of the shell and which has a downward-facing peripheral return.

According to yet another feature, the transparent plate which protects the photovoltaic cells is locked on the terminal cap by means of a screwed glazing bead.

According to an additional characteristic, the erectile hollow body is surmounted by a bollard cap which extends inwards by an axis central fitted with a rack on which a pinion controlled by the electric motorization; the electronic card, the electric motorization, the energy receiver and accumulator are mounted on fixed support means fitted in the receiving well.

Still according to the invention, the retractable bollard has an internal barrel fixed with bottom. This barrel is placed in the receiving well, inside the size of the hollow body surmounted by the terminal cap; it serves as support for motorization, battery, electronic card and receiver radio.

According to an additional characteristic, the central support axis of rack is guided in a slide which is integral with the fixed shaft and which is fitted with interior sliding pads.

However, the invention will be further illustrated, without being in any way limited, by the following description of a particular embodiment, given solely by way of example and represented in the appended drawings in which:

• Figure 1 is a general view which shows the retractable terminal according to the present invention on a reserved parking space, in the erected position;
• Figure 2 is a sectional view of the terminal located in its receiving well, in the retracted position;
• Figure 3 shows the terminal seen from above;
• Figure 4 is a block diagram which illustrates the connection of the various terminal control members.

Figure 1 shows the retractable terminal 1 in the high position, that is to say prohibited access, on a parking space 2 reserved for disabled. This terminal 1 operates on solar energy through sensors 3 in the form of photovoltaic cells, As will be seen below, the energy captured is accumulated in a battery which powers a electric motorization controlling the erectile part uphill or downhill. This command is carried out remotely, via a radio transmitter / receiver system operated by the person (s) having authorization to access the reserved space.

Solar collectors and energy storage ensure autonomy total of the terminal.

Figures 2 and 3 show in detail the structure of the retractable bollard according to the invention.

This terminal 1 which has a generally cylindrical shape consists of a fixed part and an erectile and retractable mobile part; she is placed in a concrete well 4 which is arranged in the ground, and which is delimited by a cylindrical shell 5 made of PVC-like plastic material, serving as formwork lost.

The fixed part of the terminal is in the form of a cylindrical barrel 6 consisting of a ferrule 7 associated with a lower bottom plate 8. The barrel 6 is placed at the bottom of well 4 and its bottom plate 8 is fixed to it by through protruding threaded rods 10. There are 10 rods three, regularly distributed, embedded in the concrete mass which defines the bottom of well 4. They are fitted with nut / lock nut type systems 12 which allow the height positioning of the barrel 6 to be adjusted, in particular to maintain a sealing space between the bottom plate 8 and the mass concreted.

Barrel 6 is made of galvanized sheet steel: its diameter is less than that of the shell 5 and it extends over a height corresponding substantially to half the height of the well 4.

A central slide 13 in the form of a steel tube with rectangular section is secured to the internal face of the bottom plate 8, by means of brackets fixing 14. This slide 13 extends on the axis of the barrel 6, from its bottom 8 and practically up to the upper edge of the shell 5, at ground level.

The bottom plate 8 also serves as a support for a radio receiver 15 as well as an electronic card 16 whose function will be detailed later.

In its upper part, the barrel 6 receives an intermediate plate 17, of general circular shape, serving as a support for an electric motorization 18 and to an energy accumulator 19. The intermediate plate 17 is disposed parallel to the bottom plate 8; it is secured on the upper border of the barrel 6 by means of fixing brackets 20. An orifice is provided don the central part of the tray 17 to allow the passage of the slide 13.

The erectile organ of the terminal is constituted by a cylindrical hollow body 22 surmounted by a terminal cap 23. The hollow body 22 / cap assembly 23 is made in one piece, in polyester-like plastic material. The height of the hollow body 22 corresponds substantially to 2/3 of the depth of the well 4; its diameter is between the diameter of the barrel 6 and the diameter of the shell 5 to be able to insert and slide between them. Terminal cap 23a a generally cylindrical shape; it extends laterally beyond the size of the shell 5 and it includes a peripheral return 24 oriented down.

Terminal cap 23 is fitted to receive two panels solar 3 in the form of photovoltaic modules. The bottom of the receptacles 25 which accommodate the panels 3 has an opening for passage junction and regulation boxes 26, from which extend the cables (not shown) for connection to the energy accumulator 19. A central rib 27 which separates the two receptacles 25 makes it possible to stiffen the structure.

The solar panels 3 are protected by a transparent plate 28 held by a peripheral glazing bead 30, in aluminum for example, screwed into the terminal cap 23. The transparent protective plate 28 is preferably made of unbreakable material, such as lexon. On the inside, the terminal cap 23 has an axial slide 31 which fits into the fixed slide 13. The slide 31 consists of a section tube square secured to the internal face of the terminal cap 23 by means fixing brackets; its length corresponds substantially to the depth of the well 4. A longitudinal rack 32 is fixed by screws or by bonding to the slide 31. This rack 32, made of a synthetic material, such ertalon for example, ensures the up and down movement of the hollow body 22 associated with the terminal cap 23: it is driven by a reduction gear 33 in engagement with the motor pinion 34 of the motorization 18. The reduction gear pinion 33 passes through a light 35 arranged in the slide 13 to drive the slide 31 in translation. The movement of translation of the slide 31 is guided by sliding shoes 36 in polyethylene fixed by screws against the internal faces of the slide 13.

The upper edge of the ferrule 5 is fitted with a collar metal 37 square-shaped. The vertical wing of this flange 37 is secured by screw with the internal face of the ferrule 5; its horizontal wing or substantially horizontal extends externally, flat on the ground. Legs anchor 38 welded on this horizontal wing are embedded in the mass of concrete to complete the fixing. The vertical flange of the flange 37 extends in the upper part to receive a lip seal 39 which comes bear against the external face of the hollow body 22, over the entire periphery of the last.

In FIG. 2, the retractable bollard has been shown in position retracted with the return 24 of the terminal cap 23 practically in contact with the ground. In this position, we notice the seal 39 arranged in the connection angle of the hollow body 22 with the terminal cap 23. This peripheral seal 39 is in permanent contact with the hollow body 22, whatever the height position of the latter.

On the other hand, in the maximum extracted position, the lower level of the body hollow 22 remains located below the level of the intermediate plate 17. The barrel 6 and the hollow body 22 thus define a sealed internal chamber which protects from humidity all the control elements.

To perfect the operation of the various control devices, advantageously, the presence of an absorption system is provided humidity inside the barrel 6 or on the intermediate plate 17.

The operation of this solar terminal is managed by the card electronic 16 receiving movement commands by radio receiver 15 associated with a transmitter owned by the operator. In Figure 2, the map electronics 16 and radio receiver 15 are positioned in the barrel 6, on the bottom plate 8; if space permits, they can also be fixed on the intermediate plate 17.

According to a preferred embodiment, the two modules photovoltaic 3 are of the monocrystalline or polycrystalline silicon type; they ensure the charge of an accumulator 19 in the form of a 12-volt battery. The motorization used is a direct current electric motor 18 operating at a voltage of 12 volts adapted to the voltage delivered by the drums. The radio transmitter / receiver system consists of hardware classic remote control powered by 12 volts, it works on length wave. The electronic card 16 is adapted to operate with a 12 volt motor and to limit the value of the standby current as much as possible; this value can be located around 10 mA.

The connection between the various control members is illustrated in the block diagram in FIG. 4.
In this diagram, it can be seen that the electronic card 16 manages the rising or falling information of the terminal from the signal supplied by the radio receiver 15 controlled by the transmitter 42. The energy required to watch the whole and when the motorization 18 is started, it comes from the battery 19 charged by the solar collectors 3. The electronic card 16 is placed at the interface between the battery 19 and the electric motorization 18.

To perfect the operation, the terminal includes means which automatically stop the motorization in the high position and in the hump position. These means serve as limit switches; they consist of magnetic type sensors / detectors arranged on the slide 31 and on the slide 13 and which send their information directly to the management card 16. In FIG. 4, these detection means are referenced 43. In position maximum extract, the height of the terminal is of the order of 35 cm; in position reentry overflows a few cm, depending on the thickness of the hat 23.

It is also possible to provide an anti-obstacle security system 44 reversing the uphill operation as soon as the terminal cap 23 encounters an obstacle (for example a parked vehicle). These particular security means can be implemented by detection of the amperage of the motorization 18: if an obstacle blocks the terminal cap 23, this amperage increases and above a predetermined threshold the system detection address a movement reversal order via of the electronic card 16.

The detection of an obstacle under the perimeter of the bollard cap, in downward movement, causes the motorization 18 to stop immediately on electronic card order 16.

The reference signs inserted after the technical characteristics mentioned in the claims are intended only to limit the understanding of them and in no way limit their scope.
