Description

METHOD AND APPARATUS FOR CONTROLLING A BARRIER

TECHNICAL FIELD

This invention relates to barrier opening methods, devices and systems. More particularly, but not exclusively, the present invention relates to an apparatus and method of operating a door.

BACKGROUND ART

Conventional barriers, in particular doors, are required in buildings and outside areas to retain or control air conditions and temperatures in different areas and for noise insulation between rooms or areas, and to allow for persons or animals to pass through. A disadvantage with door with a handle is that it requires operating the handle by hand or otherwise to open the door. This can be difficult if a person or animal can not readily activate the handle to open the door. In the case of a person in a wheelchair, it can be considered inconvenient and cumbersome to regularly navigate through the door by activating the handle and pushing or pulling the door open.

Door openers for hanging and sliding doors for garage openings and sliding glass doors in commercial buildings are common. Many use drive train mechanisms to open and close such doors. Door openers for swinging doors are less common, partly due to the leverage required when opening a door, usually from the hinged side. Some designs incorporating cam levers and associated arms require considerable force and thus require large and sufficiently powerful actuators to open and close the door. The size of such actuators can be costly and the power drawn to operate such actuators can be expensive to run.

It is an object of the present invention to provide an apparatus and/or system and/or method of controlling the operation of a barrier which overcomes at least some of the abovementioned problems, or which provides the public with a useful choice. SUMMARY OF THE INVENTION

According to a broad aspect of the invention there is provided an apparatus for controlling the operation of a barrier, the apparatus including an actuator means, a control means, a drive means and a drive arm, the drive arm being elongate with a longitudinal axis being parallel with the direction of travel of the barrier, the actuator means being activated to generate a signal to the control means, the control means being configured and arranged to receive the signal and activate a drive means, the drive means being associated with the drive arm, in use, to exert a force against the drive arm to move the barrier in the direction of travel.

Preferably the drive arm is a rack having teeth aligned on one side of the arm, and the drive means is a motor having a shaft with a pinion attached thereto, the pinion being positionable, in use, to engage the teeth in the rack and rotate to move along the rack.

Preferably the rack is attachable to a fixed support means adjacent the barrier and the drive means is attachable to the barrier.

Desirably the apparatus further includes a housing to which the drive means is mounted, the housing being attached to the barrier, and having a rotatable guide wheel attached to the housing and being located adjacent the other side of the rack from the teeth to guide the movement of the rack.

Desirably the actuator means is any one or more of the group comprising of a movement sensor, an infrared beam, , a microwave beam, a contact switch, a remote control actuator and/or a push button. Additionally the actuator means is a remote control device adapted to activate a transmitter to send an activation signal to a receiver associated with the control means. Preferably the control means is microprocessor adapted to control the operation of the door.

Desirably the apparatus further includes a rotatable guide wheel located adjacent the other side of the rack from the teeth to aid in the free travelling of the drive arm.

According to a second broad aspect of the invention there is provided a computer program for operating the apparatus of the first broad aspect of the invention, the program including the steps of:

(i) initiating a set-up routine to check settings and configuration;

(ii) operating the apparatus in standby mode with the barrier in a predetermined first position; (iii) receiving an activation signal and activating barrier to move to its predetermined second position;

(iv) activating a predetermined count down cycle of the time for maintaining the barrier in the second position, and when reached; (v) activating the drive means to move the barrier toward the first position; and when reached (vi) resetting the program to step b.

Advantageously in step c. if resistance to the barrier opening is detected, activating the drive means to reverse the barrier to the first position and to reset the program to step b.

Preferably in step e. if resistance to the barrier closing is detected, activating the drive means to reverse the barrier to the second position and to reset the program to step c.

Preferably the computer program further includes the preliminary step of setting all the default or preferred barrier operation settings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to figures 1 to 3, an apparatus, generally referred to as 1, for operating a barrier according to preferred aspect of the invention, is illustrated.

The barrier can include a door, window or hatch or the like, such barrier being adapted to swing or pivot horizontally or vertically, or slide horizontally or vertically. In the non- limiting preferred embodiment herein described the barrier will be in the form of a swinging door. However, it will be appreciated that the apparatus 1 of the invention may have application in association with, for example, gates, doors, windows, cat flaps, animal stock control barriers. The apparatus 1, includes an actuator means 2 to provide a signal via a hard wire 3 or by wireless means such as radio frequency, to a control means 4 to operate a door 5. The actuator means 2 may include any form of suitable object or person sensing means and include, for example, an infrared or microwave beam, a movement or pressure sensor, a push button and/or a remote control device 6. The remote control device 6 can be carried by a person wishing to operate the door 5.

For the preferred embodiment described the actuator means is a movement sensor 2. The movement sensor 2 can be attached to a fixed support structure, such as on a wall above a door frame 7 or in any other suitable and desirable position for detecting or sensing purposes. The movement sensor 2 should detect when a person, animal or moving object is present in the sensing area adjacent either side of the door 5. It will be appreciated that separate movement sensors can be mounted above the door 5, or adjacent to or in proximity of the door 5, and/or be located on both sides of the door 5.

It will be appreciated that the invention is particularly advantageous in environments where objects are being led ahead of persons and the manual opening of a door, whether swinging or sliding, is inconvenient. For example, wheelchairs, baby prams or buggies, trolleys or moving hospital beds.

When the movement sensor 2 is triggered, it generates an activation signal sent via cable 3 to the control means 4. The control means 4 is configured and arranged to process signals from various sensors in the apparatus 1 and desirably includes a microprocessor programmed to control the operation of the door 5. The control means 4 is preferably programmed to time out for a predetermined period of time to ensure the door 5 is open for enough time to allow a person, animal or object to pass through, or for any other time out period required for the opening of the door 5. Further details on the operation of the control means 4 are described below with reference to figure 4. The door 5 is operated by a drive means 8 being associated with a drive arm 9, the drive means 8 exerting a force against the drive arm 9 to move the door 5 in the direction of travel, indicated by the arrow A in figure 3. The door 5 in this embodiment is a hinged swing door. In this embodiment the drive arm is in the form of an elongate and curved rack 9 with a longitudinal axis being parallel with the direction of travel of the door 5.

The drive means 8 is desirably in the form of a bi-directional motor. The motor 8 is mounted to a housing 10 that is preferably attached by fasteners to the door 5. Alternatively the housing 10 can be attached to a fixed support structure, for example, the door frame 7, and the rack 9 can be attached to a barrier or door 5.

The motor 8 is preferably a variable speed motor and is desirably self-sensing. The motor 8 is provided with a shaft 11 that extends above the housing 10. The motor shaft 11 can be adapted with a suitable drive member 12 in the form of a cog or pinion that engages the teeth 13 of the rack 9.

The rack 9 is advantageously guided by a guide means in the form of a rotatable guide wheel 14 that ensures the rack 9 engages the pinion 12 and aids in the free travelling of the rack 9. The rack 9 can be composed of any suitable and durable material and is desirably made of steel.

The rack 9 is attachable to a fixed support means in the form of a door frame 7. One end of the rack 9 is adapted with an aperture 15 to be pivotally attached by a pivot pin 16 to a bracket 17. The bracket 17 is desirably attached at a predetermined distance from the side of the door or hinged pivot point for the swing door 5. This is due to the arc in the rack 9 that is set at an angle substantially parallel to the swinging arc of the door 5. In this embodiment of the invention the centre of the bracket 17 is set at a distance of substantially about 16 centimetres from the pivot point or hinge pivot point of the swinging arc of the door 5. In this non-limiting embodiment two contact switches 18 and 19 are used to set the desired travelling distance between the closed position and the open position of the door 5. Contact switch 18 is positioned outside of the pinion 12 from the door 5 and is connected to the control means 4. A stop block 20 is removably attachable to the rack 9 and in this embodiment is preferably fastened through an aperture 21 in the rack 9. Other apertures 21 are located in a spaced apart arrangement along the distal end of the rack 9 to allow a user to set the maximum travelling distance of the pinion 12 along the rack 9 and hence the maximum opening of the door 5. It will be appreciated that the stop 20 can be moved to be set about other apertures 21, and that any desirable length of rack 9 or number of apertures can be provided in the rack 9.

The housing 10 is advantageously adapted with lugs positioned to allow the contact switches 18, 19 and the pinion 12 to be repositioned to align with the flipside of the rack 9 in the alternative set up arrangement of the swing door 5 being opened from the other side of the door 5. That is, the hinges are mounted on the right side of the door and not the left side as shown in figures 2 and 3.

It will be seen then, in use, the pinion 12 will track along the teeth 13 of the rack 9 at a predetermined speed until the stop 20 triggers the switch 18. The signal generated will be processed by the control means 4 and the control means 4 will cause the motor 8 to stop operating.

The contact switch 19 is positioned such that when the door 5 is activated to close, at the point where the door has just closed, the bracket 17 will engage the switch 19 and the control means 4 will cut power to the motor 8.

The control means 4 is preferably microprocessor controlled in accordance with a second aspect of the invention. The microprocessor and other associated circuitry is mounted on a printed circuit board, as indicated by the numeral 4, and the printed circuit board is conveniently attached to the housing 10. The control means 4 and the motor 8 are powered by any suitable and available electrical power supply 28. It will be appreciated that the electrical power may be desirably supplied by a domestic or commercial power supply. Suitable transformers may be used as required and in this embodiment a mains cable 22 to the controller 4 is used. A suitable transformer 23 converting from mains A.C. power to D.C. power is used. Desirably a 12 volt D.C. power supply is used to power the apparatus 1.

The apparatus 1 can be retro-fitted to or constructed to be integral with a barrier. In this one embodiment the apparatus 1 is shown as a retro-fit in that the apparatus 1 can be attached to an existing swing door 5.

A dip switch 24 and an potentiometer 25 are provided to set the motor speed and the dwell time for the time the door 5 remains open. The motor 8 is set at the desired speed as it tracks along the rack 9. The motor 8 speed is variable, and the dip switch 24 is preferably used to select a desirable opening or closing speed. A slow default speed also exists and this speed is activated if or when an object or person obstructs the movement of the door 5. The dip switch 24 and the potentiometer 25 are associated with the control means 4 and are mounted on the printed circuit board onto which the controller is based.

A user selects a desired motor speed setting on the dip switch 24 by selecting the speed mode on the dip switch 24 and then adjusting the potentiometer 25 until the desired speed is selected. A user may ensure the speed is not adjusted by changing the setting on the dip switch 24 to "saved mode".

The dwell time settings can also be made by use of the dip switch 24 and the potentiometer 25. The dwell time is the time period to which the door 5 is kept open and can be at least 1 second. The dip switch 24 used in this embodiment can be set for a time period of up to 35 seconds although it will be appreciated that longer periods can be set according to an alternative embodiment of the invention. A user selects a desired dwell time by selecting the "dwell mode" on the dip switch 24 and then adjusting the potentiometer 25 until the desired dwell time is selected. A user may ensure the dwell time is not adjusted by changing the setting on the dip switch 24 to "saved mode".

It will be appreciated within the scope of the invention that the speed and dwell time parameters can be set locally or remotely. In an alternative embodiment it will be appreciated that the remote control device 6 can be adapted to allow a user to set the operating parameters of the apparatus 1 and communicate such commands via a transmitter in the device 6 to a receiver in the control means 4.

A cover 26 can be shaped to envelop the components of the apparatus 1 on the housing and attach to the housing also. An aperture 27 is in the cover 26 to allow the rack 9 to pass therethrough.

Referring now to figure 4, a flow chart of processing steps for controlling the operation of the door, is illustrated.

The control means 4 may be programmed by a suitable computer program to operate the apparatus 1 in accordance with an aspect of the invention.

At power up step a. in the computer program is with initialising a set up routine. A test cycle is run and the preferred settings for the apparatus 1 are established and a check of the contact switches and the sensors 2 operating are determined. Once the test cycle has completed the control means 4 moves to the standby mode of step b.

In step b. the door 5 will be in its predetermined start or first position which is generally when the door 5 is closed. The standby mode will be considered the default position for the door 5. Unless activated, the door 5 will remain closed. When the door 5 is activated by the actuator means 2, step c. in the program is initiated. In step c. the program commands the control means 4 to activate the motor 8 to drive the pinion 12 along the teeth 13 of the drive arm or rack 9 until it is stopped by the contact switch 18, at which time a feedback signal to the control means 4 will cause a command from the control means 4 to stop the motor 8 at the end of the rack 9 in a predetermined second position that is generally with the door 5 in a desirable open position.

The door 5 may be activated manually by being slightly pushed or pulled. The apparatus 1 is configured such that when the door 5 is closed and in standby mode in step b. the contact switch 19 is in contact with the bracket 17. By pushing or pulling the door the contact switch 19 state is changed and a signal is sent to the control means 4 to initiate step

The computer program is preferably loaded with default speed settings that can ensure that the door 5 slows down at it nears the contact switches 18, 19. This is desirable as the variable speed settings can reduce undue slamming of the door 5 and reduce the risk of jams in the door by reason of someone not being quick enough to pass through or move out of the path of the closing door 5.

If the opening of the door 5 is resisted by an obstruction or otherwise, a feedback signal is received by the control means 4 and step cc is initiated whereby the control means 4 commands the motor 8 speed to reverse pause and then continue to gently open for a predetermined time and reset the program to step b. in the standby mode.

If the door 5 is not resisted, or is again re-activated, as aforementioned step c. is repeated.

When the door 5 is stopped at the open position, step d. is commenced. A predetermined count down cycle or dwell time operates whereby the door 5 is kept open for as long as a user requires to pass through the door 5. Dwell times may be set by the dip switch 24 and adjusting the potentiometer 25 and may be any suitable period of time, commonly

1U between 1 to 35 seconds. When the time period has elapsed, step e. is commenced. Step e. is when the door 5 is activated to close and a control signal reverses the direction of the motor 8 to close the door 5.

When the door 5 is reclosed, the program moves to step f. in the process. At this point, when the contact switch 19 activates by being triggered by the bracket 17 closing the switch 19, the control means 4 sends a signal to stop the motor 8 and the program is reset to step b. in standby mode.

If the closing of the door 5 is resisted by an obstruction or otherwise, a feedback signal is received by the control means 4 and step ee is initiated whereby the control means 4 commands the motor 8 direction to reverse and to reset the program to step c. in the open door mode.

It will be appreciated that the invention has particular application where a barrier, for example a window or door, is difficult or inconvenient to open or close or where a window or door is required to be open at strict times. For example, a window or windows located at an out of reach location can be conveniently opened and closed as required by the remote control device 6.

The invention may be suitable for applications such as controlling windows and doors in animal or bird cages and compounds at a zoo where it is convenient, and in some cases safer, to activate doors or windows from a distance.

It will be further appreciated that the apparatus 1 may be adapted with door latch means or locking means to lock or unlock the door remotely.

It will also be appreciated that in the event that an electrical power cut or failure exists, the drive mechanism attachable to the drive arm can be manually overridden, thus allowing the door to be manually opened and closed. It will be further appreciated that an advantage with the invention is that it is a design that can be easily installed, particularly with a common swing door.

Wherein the aforegoing reference has been made to integers or components having known equivalents, then such equivalents are herein incorporated as if individually set forth. Accordingly, it will be appreciated that changes may be made to the above described embodiments of the invention without departing from the principles taught herein.

Additional advantages of the present invention will become apparent for those skilled in the art after considering the principles in particular form as discussed and illustrated. Thus, it will be understood that the invention is not limited to the particular embodiments described or illustrated, but is intended to cover all alterations or modifications which are within the scope of the appended claims.
