FR2751690A1 - Gate opener controller for domestic entrances - Google Patents

Abstract

The controller has one electronics unit (6) mounted on each respective gate leaf (3). Each unit has a geared electrical motor with connecting rods (10) attached to each gate leaf so the electrical motor can push the gate open or closed. Once the gate is closed, the force exerted by the gearing prevents the gate being pushed open. The electronics unit is controlled by an electronic card which is contained in a housing (5) and has receiver and decoder components which are used for a signal received via an antenna (7) from a handheld unit (8). Two batteries supply the components and a solar panel (9) ensures the batteries are charged.

Description

 The present invention relates to a gate maneuvering machine, using two reduction gearboxes with rods that can be, for example, used as a fence gate or private dwelling.

Thus, gates are known of which the leaf or opening, articulated in a conventional manner on hinges of vertical axis, is opened or closed using a automaton based on an articulated jack, by one of its ends, on the leaf itself, and by its other end on the pillar carrying the leaf. These gates have great disadvantages, in particular the fact that the jack always works in very bad conditions, in a direction making a small angle with the plane of the gate. The jack exerts very significant forces on a fixed joint, the position of which must moreover be determined with very great precision. We therefore often see the tearing of seals or a deterioration of the abutment
Portals are also known in which an electric motor makes it possible to rotate the axis of the portal itself. Such an installation requires the installation of the motorization in a pit under the axis of rotation of the leaf, resulting in extremely high installation costs.

 In all cases, it is necessary, to avoid breakdowns, to provide an electromechanical lock accessible from the outside, which increases the cost and makes the installation more vulnerable. the present invention proposes to remedy these drawbacks and to provide a gate automaton of reduced cost and of easy installation, and which also does not involve risks of deterioration of the leaf, of the pillar or of the installation itself .

 Thus, the device according to the invention can be installed easily by the individual himself, without requiring special knowledge.

Another object of the invention is to allow the gate to be locked in the closed position without having to resort to an electromechanical lock.

The subject of the invention is an automaton composed of an electronic unit, two motor reducers with portal operating rods using an electric motor and in which an electric motor reducer assembly, fixed to the rear of the pillar of each leaf, has a vertical outlet axis to which is fixed the end of a horizontal arm perpendicular to the axis, the other end of which is thus caused to traverse an arc of a circle, this other end being itself articulated to a link, itself hinged in one place of the leaf. The advantages and characteristics of the invention will appear on reading the following description, given by way of nonlimiting example, with reference to the drawings in which:
- Figure I shows the automat in a pillar gate assembly.

- Figure 2 shows a housing (6)
- Figure 3 shows the mechanical locking and unlocking of the assembly
- Figure 4 represents the points of attachment of the automat to the pillar
- Figure 5 shows the points of attachment of the automation to the leaf
- Figure 6 shows a brief description of the kinematics
- Figure 7 shows a summary description of the electronic part
- Figures 8 and 9 show the flowcharts for opening and closing the gate
The gear motor with connecting rods shown is intended to open the leaf 1 articulated on the pivot axis or hinge (2) fixed on a pillar (3) as shown in Figure 1.

 An internal stop in the gear motor determines the closed position of leaf 1.

 The portal link motor-reducers according to the invention are fixed against the rear face of the pillars (3) and contained, in part, in metal casings (6). The boltier (5) houses elements known per se, namely a conventional pocket transmitter (8), a receiver and a decoder making the electronic unit sensitive only to the code of the owner of the automaton tuned on the antenna (7) for receive the signal emitted, this set of management of the gearmotors with connecting rods is articulated around an electronic card (15) of two batteries supplying the low voltage current necessary to supply the components, electric gearmotors and a solar panel (9) to maintain the charge of the batteries.

The housings (6) are made of folded sheets and assembled by welding see figure (2). They are mounted on plates (16) by means of slides and fixed by screws. The plates (16) are mechanically welded parts on which a certain number of machining operations are carried out which are used to fix the automata to the pillars of the gate, to fix the motors, to adjust the stops and to the passageways of the axes connecting rod driven by two pinions Z1 and
Z2 ,.

 Locking is obtained here by aligning the 2 rods (10) and (11), that they do more than one, as for the jacks, this configuration develops a significant reaction R for a closing force F given as shown in figure (2). The low torque of the gearmotors with connecting rods (27 Nm) provides safety for stopping on obstacles and ensures reversibility for manual opening.

 In the event of a battery failure or the operation of the automatic device according to the invention, it is easy to open the gate from the inside by removing the links by exerting a small force in the direction D in order to be able to pivot the leaf around its axis as shown in figure (2).

 To open the leaf from the outside in the event of failure, it suffices to provide a passage P in the leaf so as to allow the introduction, by the latter, of a key or tool of suitable shape which comes to desalinate the rods as previously, see figure (2).

 One of the advantages of the invention is that it does not have a stop on the ground, they are integrated into each gear motor with rods, they are screwed in two lights by means of a domed head bolt with square collars called bolt "JAPY" (15) and cylinders (14) tapped then drilled in the normal way to ensure a strong tightening using a rod, which allows a simple and precise adjustment see figure (3).

One of the advantages of the invention is its simplicity of installation, in fact it is fixed to the post by four screws on the rear face of the mounting plate (16) of the gear motor as shown in FIG. 3 and by two screws on the leaf at the end of the rods (11) via the tab (12) as shown in figure (4). The electrical connection between the components of the PLC is supplied pre-wired.

The transmission of the movement is obtained by a set of pinions (Z1) linked to the link (10) and (Z2) mounted at the output of the gear motor see figure (5).

The torque limitation is given directly by the design of the low-voltage 12-volt DC, 27 Nm motor-reducer, to stop the leaf in its path if it comes into contact with an obstacle during an opening or closing cycle.

The electronic card has no settings which simplifies its installation and use. It is of semi-automatic type, can be controlled by a radio control, a video door entry unit, a key control, an alfa numeric keypad see diagram (6) in which A and E represent the opening relays, B and D are the closing relays, C the relay for the closing offset between the two leaves to avoid blocking depending on the type of leaf, F is the opening time,
G the closing time, H the time difference between the two leaves, I the directional remote control which supplies either during opening or closing depending on the cycle, J the installation protection fuse, K and L the connection of the moto- reducers, M the electromagnetic lock (optional), N the external control for opening or closing, O the possible control of the electromagnetic lock, the input of the PLC supply, Q the connection of the receiver (frequency 315 Mhz) and R the connection of the solar charger or other.

To avoid any incident, once an opening or closing cycle has started, the card does not take into account any false command manipulation, as shown on the opening and closing cycles in figure (7) and ( 8).
