Description

FIELD OF THE INVENTION

This patent specification relates to the field of devices for opening and closing of a door. More specifically, this patent specification relates to a device governing the opening and closing of a door.

BACKGROUND

As a caregiver of an elderly person with an assistive walking device (commonly referred to as a walker), we asked what we could do to make her life easier. She requested an easier way for her to open and close the doors so that she could get through them by herself. We researched the most common reason for falls of the elderly and handicapped and found that trying to maneuver beyond a current level of functioning was a major problem. It was apparent that backing up, and one handed operation of an assistive walking device, (Walker, cane or crutches) is a very unsafe situation. Opening a door in a wheelchair is also a difficult maneuver and often requires unsafe reaching forward. Having doors for bedroom, bathroom, etc. open upon approach, and being able to continue in a forward motion and close without turning around, would greatly increase safety and convenience.

Prior art has only approached various permanently fixed door and frame mounted devices for various aspects of operating doors such as patent awarded to Albrecht in 1991, U.S. Pat. No. 5,040,331 A. None have addressed the need for remote controlled door operation and a single-point mounting system that is non-marring, semi-permanent door attachments in pivotal hinged doors. Many inventions, such as those disclosed in U.S. Pat. No. 5,727,348 filed by Arnel et al, address only the remote closing of a door. Many others, such as those disclosed in U.S. Pat. No. 5,881,497 filed by Borhardt et all and U.S. Pat. No. 5,930,954 filed by Hebda et al, address opening by fixed frame and door mounting devices, using mechanically mounted devices on both the door and doorframe or wall, as well as, using timing devices for closing. Other inventions, such as those disclosed in U.S. Pat. No. 6,553,717 filed by Stanley Works, use the traditional overhead two point mount to the top of the door and the doorframe as frequently seen in commercial door closing, again only allowing the operator to fully open or fully close the door. The most common patents found in this field are for the use of remote controlled door opening and closing for overhead garage door operation. There are many door closers that are single function such as disclosed in WO1998044230 A1 which is portable and can be operated from a remote location. These single function operators, however do not address the needs of a feeble person who would like to open their door partially, to let the dog in, and then close it again from a chair.

There are many known door opening devices used for opening and closing of swing doors wherein an operation device may be mounted in close proximity to the door frame and coupled to the swing door to control the operation of the door. In U.S. Pat. No. 4,727,679 awarded to Stanley works, and EP 1671292 A4 awarded to Sanidoor LLC., there are disclosed systems for automatically controlling the operation of a swing door which includes an electronic controller responsive to various input signals such that initiation of an opening sequence may be accomplished by conventional actuation means such as floor mats, hand wave detection, voice command or other conventional systems. After the door is opened, closing thereof occurs after a short delay rather than using input from the individual. This and other systems utilize a transmission system include pulley drive shafts, idler shafts, and linkage systems using a crank arm. Most of the prior art illustrate door openers used in industrial door opening devices which are commonly used at retail stores or other commercial areas and must operate from a 120 volt line source and effects only fully open or fully closed doors by actuation, command or timer.

There are also other systems, which provide remotely controlled, opening and closing of doors, windows or the like such as found in Tolson's U.S. Pat. No. 3,337,992. In this patent, a remote sensing device is utilized to actuate a mechanical door opening or closure system in response to various selected physical conditions or other criteria. This system includes programming means to control the overall operation of the system enabling various functions to be selectively achieved. The system is complicated and cumbersome to utilize effectively, and may be prone to breakdown and inefficient operation.

There is a great need for a device to increase the safety of temporarily or permanently handicapped individuals while navigating with assistive walking devices and wheelchairs, through doors and to provide free access of swing doors. To be an effective door opener/closer for this population the device should meet certain standards: 1) Scalable multi-door operation system. The system needs to be able to operate one door or up to six or more doors from a portable hand held or mountable remote control. 2) It is important that the remote control opening and closing device be easily installed, with a semi permanent system with no marring or drilling into the door, so as to enable retrofitting to an existing door. 3) Utilize a single point mounting system, rather than two points connected with an articulating arm, for ease of installation and flexibility to re-mount in any swing door location. 4) The handheld or mounted remote control device must be simple to use and easily operated by elderly and handicapped individuals. 5) The activating signals used should be of the frequency to prevent accidental opening or closing from occurring based upon signals generated from other remote devices. 6) the device must be easily opened and closed manually without adaptation, for emergency egress and convenience of non-handicapped access. 7) It is also desired that the opening and closing system be cost effective and convenient to use. None of the current art meets all these standards.

BRIEF SUMMARY OF THE INVENTION

An automatic door opening and closing device is provided. The device may be configured to move a door in a first direction, move the door in a second direction, and to stop the movement of the door thereby enabling the device to open the door, close the door, or stop the door. In some embodiments, the device may include a housing which may contain a control unit. A motor may be in electronic communication with the control unit, and a wheel may be coupled to the motor so that the motor may be operable to rotate the wheel in a clockwise direction and in a counter clockwise direction. A chassis may be configured to couple the motor to a door so that the wheel is in contact with a ground surface 600 below the door. The motor may be operable to rotate the wheel clockwise across the ground surface to motivate the door in a first direction, and the motor may be operable to rotate the wheel counterclockwise across the ground surface to motivate the door in a second direction. By motivating the door in either the first direction or the second direction, the device may be configured to move the door into, out of, and between the open and closed positions.

In further embodiments, the wheel may be movably coupled to the chassis so that the wheel may move relative the door to which the device is coupled.

In further embodiments, the device may include or may be in communication with a remote control configured to generate a wireless signal. The control unit may then control the motor to rotate the wheel when the device receives the wireless signal from the remote control.

In yet further embodiments, the device may be in communication with a client device, such as a smart phone, that is configured to generate a wireless signal. The control unit may then control the motor to rotate the wheel when the device receives the wireless signal from the client device.

In still further embodiments, the device may include or may be in communication with a translator. A translator may receive a wireless signal from a client device and then output another wireless signal to the device to enable communication between the client device and the device if they operate on different frequencies or with different communication protocols. Upon receiving a wireless signal from the client device via a translator, the control unit may then control the motor to rotate the wheel when the radio module receives the wireless signal from the translator.

The present invention will now be described by example and through referencing the appended figures representing preferred and alternative embodiments. FIGS. 1-5 illustrate examples of an automatic door opening and closing device (“the device”) 100 according to various embodiments. In some embodiments, the device 100 may comprise a housing 11 which may contain a control unit 50. A motor 12 may be in electronic communication with the control unit 50, and a wheel 13 may be coupled to the motor 12 so that the motor 12 may be operable to rotate the wheel 13 in a clockwise direction and in a counter clockwise direction. A chassis 14 may be configured to couple the motor 12 to a door 500 (FIGS. 10 and 11) so that the wheel 13 is in contact with a ground surface 600 (FIG. 10). The motor 12 may be operable to rotate the wheel 13 clockwise across the ground surface 600 to motivate the door 500 in a first direction, and the motor 12 may be operable to rotate the wheel 13 counterclockwise across the ground surface 600 to motivate the door in a second direction. By motivating the door 500 in either the first direction or the second direction, the device 100 may be configured to move the door 500 into, out of, and between the open and closed positions.

A housing 11 may be configured in any shape or size to preferably cover one or more elements of the device 100 such as the motor 12 and the control unit 50. Generally, the housing 11 may be shaped to allow all or portions of the wheel 13 to extend past the bottom of the housing 11 so that the wheel 13 may be positioned proximate with the bottom of a door 500 and in contact with the ground surface 600 below the door 500. Optionally, a housing 11 may comprise a top wall 15, front wall 16, a first side wall 17, a second side wall 18, and/or a bottom wall 19. In some embodiments, a bottom wall 19, front wall 16, and/or any other portion of the housing 11 may comprise a wheel aperture 21 which may allow portions of the wheel 13 to extend through those portions of the housing 11. A housing 11 may be made from or comprise a substantially rigid material such as steel alloys, aluminum, any other type of metal or metal alloy, various types of hard plastics, such as polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC), polycarbonate, nylon, Poly(methyl methacrylate) (PMMA) also known as acrylic, melamine, hard rubbers, fiberglass, carbon fiber, resins, such as epoxy resin, wood, other plant based materials, or any other material including combinations of materials.

The device 100 may comprise one or more motors 12 which may be coupled to the wheel 13 and which may be operable to rotate the wheel 13 in a clockwise direction and in a counter clockwise direction. In some embodiments, the motor 12 may comprise a DC reversible motor with a shaft spindle 34 to which the wheel 13 may be coupled to provide the axis of rotation for the wheel 13.

The device 100 may comprise a chassis 14 which may be configured to couple the motor 12 to a door 500 (FIGS. 10 and 11) so that the wheel 13 is in contact with a ground surface 600 (FIG. 10). In some embodiments, the chassis 14 may be removably coupled to the door 500 with removable adhesive, removable adhesive tape, removable fasteners, such as hook and loop type or Velcro® fasteners, magnetic type fasteners, threaded type fasteners, sealable tongue and groove fasteners, snap fasteners, clip type fasteners, clasp type fasteners, ratchet type fasteners, or any other removable coupling method. In other embodiments, the chassis 14 may be bonded, riveted, or otherwise coupled to a door 500 in a substantially non-removable manner.

In some embodiments, a chassis 14 may be integrally formed with the housing 11. In other embodiments, a housing 11 may function as a chassis 14. In preferred embodiments, the chassis 14 may be coupled to a door 500 and one or more elements of the device 100 may be coupled to the chassis 14. A chassis 14 may be of any shape or size and preferably made from or comprise a substantially rigid material. In further preferred embodiments, one or more elements of the device 100, such as a motor 12, a wheel 13, and a transmission 22, may be movably coupled to the chassis 14 so that the elements may be movable relative to one or more portions of the chassis 14.

In preferred embodiments, the motor 12 and/or wheel 13 may be movably coupled to the chassis 14 as shown by FIG. 4 in which the wheel 13 is relatively closer to the top wall 15 and FIG. 5 in which the wheel 13 is relatively farther from the top wall 15. By being movably coupled to the chassis 14 the motor 12 and/or wheel 13 may be afforded amount of travel so that the motor 12 and/or wheel 13 may move relative to portions of the chassis 14 which are coupled to a door 500. A motor 12 and/or wheel 13 may be movably coupled to the chassis 14 with any type of movable linkages or suspension, preferably having a tensioner 28 which may be configured to tension one or more movable linkages and, therefore, the wheel 13 into contact with the floor surface 600 that is below the door 500 to which the device 100 is coupled.

In still further preferred embodiments, the chassis 14 may comprise a slide 24 and a channel 25, and the slide 24 may be movably coupled to or within a channel 25 so that the channel 25 and slide 24 may function as a movable linkage or suspension. The channel 25 may be coupled to the door 500 and one or more elements of the device 100, such as a motor 12, a wheel 13, and a transmission 22, may be coupled to the slide 24. Portions of the slide 24, such as a tongue 26, may be movably coupled within or to the channel 25 to allow the tongue 26 to slide generally up and down the channel 25 while the device 100 is coupled to a door 500. In this manner the wheel 13 may be allowed to travel up and down over carpet, rugs, pencils, small toys, and other small objects frequently found on the floors of buildings by being allowed a distance of travel provided by the distance the tongue 26 may slide generally up and down the channel 25. Optionally, the weight of the one or more elements of the device 100, such as a motor 12, a wheel 13, and a transmission 22, which are coupled to the slide 24 may serve to force the wheel 13 into contact with the ground surface 600 that is below the door 500 to which the device 100 is coupled.

In some embodiments, the device 100 may comprise a tensioner 28 which may be configured to tension the wheel 13 into contact with the floor surface 600 that is below the door 500 to which the device 100 is coupled. A tensioner 28 may comprise any object or mechanical arrangement which may be used to store mechanical energy and use that mechanical energy to tension the wheel 13 into contact with the floor surface 600 that is below the door 500 to which the device 100 is coupled. For example, a tensioner 28 may be coupled to the slide 24 and to the channel 25 and configured to tension portions of the slide 24 and the channel 25 away from each other so that a wheel 13 that is coupled to the slide 25 may be tensioned to or against the floor surface 600 that is below the door 500 to which the device 100 is coupled.

In some embodiments, a tensioner 28 may comprise any type of spring such as a Tension/extension spring, Compression spring, Constant-force spring, Torsion spring, Variable spring, Coil spring, Flat spring, Machined spring, Serpentine spring, Cantilever spring, Hairspring or balance spring, Leaf spring, V-spring, Belleville washer or Belleville spring, Gas spring or gas piston, Mainspring, Negator spring, Progressive rate coil springs, Spring washer, Torsion spring, Wave spring, Rubber band, bungee cord, or other non-metallic elastic material, or any other material or device.

As perhaps best shown in FIGS. 2-7, the device 100 may comprise a control unit 50 which may be in electronic communication with the motor 12, and the control unit 50 may be configured to control the speed, direction, and/or ability of motor 12 to rotate the wheel 13. In some embodiments and in the present example, the device 100 can be a digital device that, in terms of hardware architecture, comprises a control unit 50 which optionally includes a processor 51, input/output (I/O) interfaces 52, a radio module 53, a data store 54, and memory 55. It should be appreciated by those of ordinary skill in the art that FIG. 7 depicts the device 100 in an oversimplified manner, and a practical embodiment may include additional components or elements and suitably configured processing logic to support known or conventional operating features that are not described in detail herein. The components and elements (50, 51, 52, 53, 54, 55, 29, 12, and 59) are communicatively coupled via a local interface 58. The local interface 58 can be, for example but not limited to, one or more buses, circuit boards, or other wired connections or wireless connections, as is known in the art. The local interface 58 can have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, among many others, to enable communications. Further, the local interface 58 may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.

The processor 51 is a hardware device for executing software instructions. The processor 51 can be any custom made or commercially available processor, a central processing unit (CPU), an auxiliary processor among several processors associated with the control unit 50, a semiconductor-based microprocessor (in the form of a microchip or chip set), or generally any device for executing software instructions. When the processing unit 50 is in operation, the processor 51 is configured to execute software stored within the memory 55, to communicate data to and from the memory 55, and to generally control operations of the device 100 pursuant to the software instructions and/or from instructions received from a remote control 70, translator 80, or a client device 400. In an exemplary embodiment, the processor 51 may include a mobile optimized processor such as optimized for power consumption and mobile applications.

The I/O interfaces 52 can be used to by a user to provide input, such as which may be used to control the speed and direction of the wheel 13, to the device 100 or to receive information, such as power levels or operational status, from the device 100. The I/O interfaces 52 can also include, for example, buttons, knobs, switches, LED indicator lights, LED display, LCD display, a serial port, a parallel port, a small computer system interface (SCSI), an infrared (IR) interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, and the like.

A radio module 53 enables wireless communication to an external access device, such as to one or more remote controls 70, translators 80, other automatic door opening and closing devices 100, and client devices 400, or a network. In some embodiments, a radio module 53 may operate on with carrier frequencies such as are commonly used in commercially available RF modules, including those in the industrial, scientific and medical (ISM) radio bands such as 433.92 MHz, 915 MHz, and 2400 MHz and/or frequencies available for unlicensed use such as 315 MHz and 868 MHz. The radio module 53 may comply with a defined protocol for RF communications such as Zigbee, Bluetooth low energy, or Wi-Fi, or they may implement a proprietary protocol. Any number of suitable wireless data communication protocols, techniques, or methodologies can be supported by the radio module 53, including, without limitation: RF; IrDA (infrared); Bluetooth; ZigBee (and other variants of the IEEE 802.15 protocol); IEEE 802.11 (any variation); IEEE 802.16 (WiMAX or any other variation); Direct Sequence Spread Spectrum; Near-Field Communication (NFC); Frequency Hopping Spread Spectrum; Long Term Evolution (LTE); cellular/wireless/cordless telecommunication protocols (e.g. 3G/4G, etc.); wireless home network communication protocols; paging network protocols; magnetic induction; satellite data communication protocols; wireless hospital or health care facility network protocols such as those operating in the WMTS bands; GPRS; proprietary wireless data communication protocols such as variants of Wireless USB; and any other protocols for wireless communication.

An optional data store 54 may be used to store data. The data store 54 may include any of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, and the like)), nonvolatile memory elements (e.g., ROM, hard drive, tape, CDROM, and the like), and combinations thereof. Moreover, the data store 54 may incorporate electronic, magnetic, optical, and/or other types of storage media.

The memory 55 may include any of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)), nonvolatile memory elements (e.g., ROM, hard drive, etc.), and combinations thereof. Moreover, the memory 55 may incorporate electronic, magnetic, optical, and/or other types of storage media. Note that the memory 55 may have a distributed architecture, where various components are situated remotely from one another, but can be accessed by the processor 51. The software in memory 55 can include one or more software programs, each of which includes an ordered listing of executable instructions for implementing logical functions. In the example of FIG. 7, the software in the memory system 55 includes a suitable operating system (O/S) 56 and program(s) 57. The operating system 56 essentially controls the execution of input/output interface 52 functions, and provides scheduling, input-output control, file and data management, memory management, and communication control and related services. The operating system 56 may be, for example, LINUX (or another UNIX variant), Android (available from Google), Symbian OS, Microsoft Windows CE, Microsoft Windows 7 Mobile, iOS (available from Apple, Inc.), webOS (available from Hewlett Packard), Blackberry OS (Available from Research in Motion), and the like. The programs 57 may include various applications, add-ons, etc. configured to provide end user functionality with the device 100.
