Exemplary Method for Opening a Door Using a Motorized Door Opening Device
To most individuals, manually opening and closing of a door is relatively easy. However, for some individuals like elderly people or handicapped individuals, this task can be very challenging. A method for opening or closing a door using a motorized device that may assist elderly people or handicapped individuals is described. Reference is now made to
According to some exemplary embodiments, a motorized door opening device is configured to open a door when an activation signal, for example a wireless signal is received at 100. In some embodiments, when an activation signal is not received by the motorized door opening device, the door can be manually opened by a user, for example by applying a force against the door. In some embodiments when the door is opened manually, the motorized door opening device raises the wheel from the surface. Alternatively, when the door is opened manually, the motorized door opening device is activated and rotates the wheel on the surface. Optionally, when the door is opened manually, the motorized door opening device is not activated. In some embodiments, the wireless signal is transmitted by a user using a remote control, or a handheld device.

According to some exemplary embodiments, in response to the wireless signal the motorized door opening device lowers at least one wheel to the floor at 102. In some embodiments, the motorized door opening device waits to receive an additional signal from the user, before lowering the at least one wheel to the floor. In some embodiments, when the wheel is lowered, the motorized door opening device adjusts the pressure to be applied by the wheel on the floor.
According to some exemplary embodiments, when the wheel is in contact with the floor after receiving a wireless signal, the motorized door opening device starts to rotate the wheel at 104. In some embodiments, the motorized door opening device is configured to open and to close the door, for example by rotating the wheel in two opposite directions. In some embodiments wheel rotation time is predetermined and is in the range of 1-120 seconds. Alternatively, the wheel is rotated until the door reaches a desired opening degree. In some embodiments, the desired opening degree is predetermined and is in the range of 0.5-180° degrees. Optionally, the wheel is rotated until a signal indicating that the door has reached its desired opening degree is received.
Exemplary Device Operation Process
Reference is now made to
In some embodiments, wheel rotation time and/or wheel rotation speed are adjusted to reach the desired opening degree. In some embodiments, the desired opening degree is marked on the floor by a tag, for example an RFID tag, or a magnetic tag that will be identified by a sensor connected to the motorized door opening device, for example an RFID reader or a magnetic sensor, respectively. In some embodiments, the determined operation parameter values are stored in a memory circuitry of the motorized door opening device.
According to some exemplary embodiments, setup 108 comprises setting a parameter of the door opening device related to a door state, for example to a closed position and/or an open position of the door. In some embodiments, the parameter is adjusted by synchronizing a door state with the position of the device, for example an absolute position or a relative position of the device. In some embodiments, the position of the device is determined by setting the door in a desired state and pressing a button in a handheld device controlling the device or a button on the device itself.
In some embodiments, setup 108 comprises setting a parameter of the door opening device related to the opening direction of the door. In some embodiments, setup 108 comprises adjusting the device to operate with a self-closing door. In some embodiments, when operating with a self-closing door, the wheel is raised or is allowed to rotate freely on the surface to close the door.
According to some exemplary embodiments, setup 108 comprises adjusting the device to operate with a door that is connected to an intercom. In some embodiments, the intercom delivers signals to the door opening device, for example to open or to close the door. In some embodiments, the signals comprise wireless communication signals, for example sound. Alternatively or additionally, the door opening device transmits signals, for example wireless signals to the intercom. In some embodiments, the door opening device transmits signals to the intercom for example to unlock the door. In some embodiments, the door opening device transmits signals to the intercom to activate a speaker and/or a microphone of the intercom. In some embodiments, in setup 108, a pin code or a password of the intercom is inserted to a memory of the door opening device or to a memory of a software program controlling the door opening device.
According to some exemplary embodiments, once setup 108 is completed, the motorized door opening device operation mode is set to a standby mode at 110. In this mode, the device is ready for activation upon receiving an activation signal. In some embodiments, in standby mode, the door can be opened or closed manually without the need to activate the motorized door opening device. According to some exemplary embodiments, in a standby mode the device is configured to reduce the electric power delivered to high-energy consuming components, for example a motor and/or a wheel actuator. According to some exemplary embodiments, during standby mode the device is configured to receive an activation signal via a receiver circuitry of the device and then to shift into an active state. According to some exemplary embodiments, the received activation signal is a wireless signal, for example an infra-red signal or a Bluetooth signal, transmitted from a remote control or a mobile device.
According to some exemplary embodiments, when the motorized door opening device is at standby mode 110, the control circuitry, for example CPU 202 or 236 is in a sleeping mode. In some embodiments, during sleeping mode the control circuitry does not receive electrical power or it receives electrical power for short time periods. In some embodiments, when an activation signal is received, for example activation signal 302, the control circuitry starts to receive electric power.
According to some exemplary embodiments, upon receiving an activation signal, the motorized door opening device operation mode changes from a standby mode to an active mode at 112. In some embodiments, in an active mode, the motorized door opening device operates according to at least one pre-installed operation program. In some embodiments, operation parameter values of the at least one pre-installed operation program were determined in setup 108 and stored in the device memory, for example a memory circuitry 221. According to some exemplary embodiments, in response to an activation signal, the motorized door opening device lowers at least one wheel to the floor until the desired pressure is applied by the wheel on the floor. According to some exemplary embodiments, the desired pressure is determined during setup 108, according to the desired friction level with the floor. In some embodiments, after lowering the wheel to the floor, a motor connected to the wheel starts to rotate the wheel on the floor in a direction that causes the door to open at 114. According to some exemplary embodiments, the door is opened until it reaches a desired opening degree, as determined during setup 108. Alternatively, the door is opened until the motor stops wheel rotation, according to a pre-determined rotation time. Optionally, the door is opened, until a stopping signal is received, for example when an obstacle is found in the door opening trajectory. According to some embodiments, the door is opened until a sensor on the device, for example a magnetic sensor senses a magnetic tag or a magnetic component attached to the floor marking the desired opening degree. In some embodiments, when the magnetic sensor senses the magnetic component attached to the floor, it signals the motorized door opening device to stop the door opening process, by stopping wheel rotation. Alternatively, the door opening process is stopped when an RFID reader component of the motorized door opening device senses an RFID tag attached to the floor. According to some embodiments, the door opening process is stopped either when wheel rotation time reaches a pre-determined value, or when a sensor on the motorized door opening device senses a marking on the floor indicating the desired opening degree.
According to some exemplary embodiments, after reaching a desired opening degree, the door stays in an open position for a predetermined time to allow a user to pass through the opened door. Then, in some embodiments the door is closed by the motorized door opening device or by a door closer device attached to the door. According to some exemplary embodiments, after the door is closed, the motorized door opening device operation state changes back to a standby mode. In some embodiments, after the door is closed, the control circuitry changes its operation mode into sleeping mode.

As used herein with reference to quantity or value, the term “about” means “within ±10% of”.
The terms “comprises”, “comprising”, “includes”, “including”, “has”, “having” and their conjugates mean “including but not limited to”.
The term “consisting of” means “including and limited to”.
The term “consisting essentially of” means that the composition, method or structure may include additional ingredients, steps and/or parts, but only if the additional ingredients, steps and/or parts do not materially alter the basic and novel characteristics of the claimed composition, method or structure.
As used herein, the singular forms “a”, “an” and “the” include plural references unless the context clearly dictates otherwise. For example, the term “a compound” or “at least one compound” may include a plurality of compounds, including mixtures thereof.
Throughout this application, embodiments of this invention may be presented with reference to a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range such as “from 1 to 6” should be considered to have specifically disclosed subranges such as “from 1 to 3”, “from 1 to 4”, “from 1 to 5”, “from 2 to 4”, “from 2 to 6”, “from 3 to 6”, etc.; as well as individual numbers within that range, for example, 1, 2, 3, 4, 5, and 6. This applies regardless of the breadth of the range.
Whenever a numerical range is indicated herein (for example “10-15”, “10 to 15”, or any pair of numbers linked by these another such range indication), it is meant to include any number (fractional or integral) within the indicated range limits, including the range limits, unless the context clearly dictates otherwise. The phrases “range/ranging/ranges between” a first indicate number and a second indicate number and “range/ranging/ranges from” a first indicate number “to”, “up to”, “until” or “through” (or another such range-indicating term) a second indicate number are used herein interchangeably and are meant to include the first and second indicated numbers and all the fractional and integral numbers therebetween.
Unless otherwise indicated, numbers used herein and any number ranges based thereon are approximations within the accuracy of reasonable measurement and rounding errors as understood by persons skilled in the art.
It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination or as suitable in any other described embodiment of the invention. Certain features described in the context of various embodiments are not to be considered essential features of those embodiments, unless the embodiment is inoperative without those elements.
Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
