Description:FIELD OF THE INVENTION

[0001] The present invention relates to an assistive device for door handling and installation that is capable of assisting a user in door handling and its installing by providing a stable support to stabilize the door and then, maneuver the accommodated door in accordance to user required location where the door is required to be installed over door casing of an enclosure.

BACKGROUND OF THE INVENTION

[0002] Effective door handling and installation are essential for ensuring functionality, security, and aesthetic appeal in both residential and commercial settings. Proper handling begins with selecting doors that suit the architectural style and functional requirements of the space, considering factors such as material durability, insulation properties, and design coherence with the overall décor. Installation of the door involves precise measurement, alignment, and securing of hinges, handles, and locks to ensure smooth operation and reliable security. Attention to detail during installation prevents issues such as uneven swinging, gaps, or misalignment that can compromise functionality and energy efficiency. Professional installation techniques also contribute to the longevity of doors by minimizing wear and tear on hinges and frames. Overall, meticulous door handling and installation enhance the usability and visual appeal of spaces while providing essential security and privacy for occupants.

[0003] Traditionally available tools used for door handling and installation includes power drills, screwdrivers, levels, chisels, and hammers. Power drills are essential for drilling holes for hinges and locks, but they are often noisy and require careful handling to avoid damaging surfaces. Screwdrivers are necessary for driving screws into place but are time-consuming for large installations. Levels ensure doors are installed straight and plumb, but they may not account for uneven floors or walls, requiring additional adjustments. Chisels and hammers are used for mortising hinges and strike bars, respectively, but they demand skill to avoid splintering or damaging the door or frame. Despite these challenges, proper use of equipment ensures precise installation, enhancing functionality and longevity while maintaining the aesthetic integrity of doors in residential and commercial applications.

[0004] US2010236188A1 discloses a transport and installation system that serves the purpose of convenient moving doors from the delivery to the place of installation, positioning doors for ease of hinge installation and providing for horizontal, straight vertical and angular position of the doors with the door jam for installation of the hinge mountings. The new and unique air actuator utilizes a base, stationery vertical guides and removable attachment to a hand cart to solve the problem of handling these heavy unwieldly objects. Although US’188 relates to a door transport and installation system, however, the cited art fails in transporting the door in accordance to user specified location where the door is needed to be installed in order to assist the user in door installation.

[0005] JPH08338175A discloses a first vertical frame material is fitted to one side of a door main body in such a manner as to freely turn to form a frame door 4 by hinges. At this time, the first vertical frame material is brought into contact with the main body. First of all, the frame material is turned, and then a second vertical frame material is installed opposite to the other side of the main body. An upper frame material is fitted to the insides of the upper ends of the first and second vertical frame materials. Subsequently, both ends thereof are fixed by fixing hardwares to form a framed door. The framed door is inserted in an opening for a door and fixed to the inside of the opening. Thus, it is possible to pack up a door set in small bulk and eliminate the fear of damaging the door set during handling Though JP’175 relates to a door installation method and door set, however, the cited art has limitation in maneuver the door to location where the door is needed to be installed in order to assist the user in door installation.

[0006] Conventionally, many devices have been developed in order to install door, however the devices mentioned in the prior arts have limitations pertaining to gripping of a door and providing a stable support to stabilize the door and maneuver the door to the location where the door is needed to be installed.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of assisting a user in door installation over a door casing of an enclosure and grip the door in accordance to material type of the door, followed by maneuvering the door to the required location thereby assist the user in door installation.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0021] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0022] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0023] The present invention relates to an assistive device for door handling and installation that is capable of accommodating a door which is needed to be installed over a door casing of an enclosure and grip the door in accordance to material type of the door and maneuver the door to the required location thereby assist the user in door installation.

[0024] Referring to Figure 1, an isometric view of an assistive device for door handling and installation is illustrated, comprises of a pair of extendable U-shaped bodies 101 having an inverted L-shaped telescopic bar 102 attached on upper ends of each of the bodies 101, an artificial intelligence-based imaging unit 103 configured on the body 101 , a motorized omnidirectional wheel 104 attached with free-end of each of the bar, plurality of flaps 105 assembled on inner periphery of the body 101 and integrated with multiple motorized hinges 106, a pair of rectangular magnetic strips 107 configured on lateral sides of each of the bodies 101, and plurality of LED 108 (Light Emitting Diode) light configured on each of the body 101 .

[0025] The proposed device includes a pair of bodies 101 preferably in portable U-shape shape and extendable in nature incorporating various components associated with the device. The bodies 101 are developed to be to be installed underneath a door which is required to be installed over door casing of an enclosure. The upper ends of the bodies 101 are integrated with an inverted L-shaped telescopic bar, in such a manner that forms a M-shaped structure. The free-end of each of the bars are integrated with a motorized omnidirectional wheel 104 for maneuverability of the body 101 over ground surface. The bodies 101 are made up of any material selected from but not limited to metal or plastic that ensures rigidity of the bodies 101 for longevity of the device. The telescopic bar 102 are pneumatically powered by a pneumatic arrangement to provide extension/retraction pf the bar 102 in view of positioning the door as per requirement of the user.

[0026] The user is required to access and presses a switch button arranged on the bodies 101 to activate the device for associated processes of the device. The switch button when pressed by the user, opens up an electrical circuit and allows currents to flow for powering an associated microcontroller of the device for operating of all the linked components for performing their respective functions upon actuation.

[0027] The microcontroller, mentioned herein, is preferably an Arduino microcontroller. The Arduino microcontroller used herein controls the overall functionality of the components linked to it. The Arduino microcontroller is an open-source programming platform.

[0028] After the activation of the device, the microcontroller generates a command to activate an artificial intelligence-based imaging unit 103 integrated on one of the bodies 101 for capturing multiple images in a vicinity of the surroundings to detect exact location of the door. The imaging unit 103 incorporates a processor that is encrypted with an artificial intelligence protocol. The artificial intelligence protocol operates by following a set of predefined instructions to process data and perform tasks autonomously. Initially, data is collected and input into a database, which then employs protocol to analyze and interpret the captured images. The processor of the imaging unit 103 via the artificial intelligence protocol processes the captured images and sent the signal to the microcontroller.

[0029] Based upon the signal of the imaging unit 103, the microcontroller actuates a direct current (DC) motor associated with the wheels 104 to position the bodies 101 in proximity to the detected location of the door. The omnidirectional wheels 104 have small discs or rollers around the circumference of the wheel 104 that are powered by the associated motor, enabling the wheels 104 to move in required direction, which provide the base with the required maneuvering towards the door.

[0030] After positioning of the bodies 101 in proximity to the door, the user is then enabled to accommodate the door over the horizontal base of the U-shaped bodies 101. One of the bodies 101 is equipped with a sensing module which includes an ultrasonic sensor and a weight sensor corresponding to detection of dimensions and weight of the door, respectively.

[0031] The ultrasonic sensor of the sensing module detects dimensions and thickness of the door. The ultrasonic sensor disclosed herein, consists of an emitter and a receiver that acts as a transducer. The emitter emits ultrasonic sound waves towards door. Then, the radiation strike to the door and reflect back which are captured by the receiver. The signal is sent to the microcontroller. The microcontroller processes the received signal from the ultrasonic sensor and on the basis of time lapse in between the sent and received radiations, the microcontroller determines the dimensions and thickness of the door.

[0032] Synchronously, the weight sensor of the sensing module used herein is a kind of a transducer. The weight sensor depends on the conversion of a load into an electronic signal. The signal is a change in voltage or current otherwise a frequency on the basis of load and the signal is sent to the microcontroller for processing in order to monitor weight of the accommodated door.

[0033] In accordance to the combined signal of the sensing module, the microcontroller synchronously actuates the bars and body 101 to extend in upward direction in such a manner for positioning apex of the structure at an optimum height.

[0034] The microcontroller actuates an air compressor and air valve associated with a pneumatic arrangement consisting of an air cylinder, air valve and piston which works in collaboration to aid in extension and retraction of the bar. The air valve allows entry/exit of compressed air from the compressor. Then, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the bar 102 and due to the increase in the air pressure, the piston extends. For the retraction of the piston, air is released from the cylinder to the air compressor via the valve. Thus, providing the required extension/retraction of the bar 102 for positioning apex of the structure at an optimum height. All the pneumatically operated components associated with the device comprises of the same type of pneumatic arrangement.

[0035] Simultaneously, the microcontroller actuates a motorized drawer arrangement integrated within the bodies 101 incorporating over the horizontal base of each of the bodies 101 such that extends/ retracts the length of the horizontal base as per detected thickness of the door, for gripping the door in a secured manner.

[0036] The drawer arrangement consists of a motor, hollow compartment and multiple compartments that are connected with sliders. After actuating by the microcontroller, an electric current pass through the motor of the drawer mechanism and energized the motor. The energized motor further actuates the compartments which are initially at the stowed condition to move in a successive manner within the hollow compartment and extends length of the compartments. Simultaneously, each of the compartments having a fixed groove track, wherein upon actuation of the slider, the motor of the slider gets energized and provides a movement to the compartment to move in a linear direction on the groove track of the successive compartment as directed by the microcontroller and extends length of the bodies 101.

[0037] The microcontroller then actuates a direct current (DC) motor associated with the wheels 104 to position the bodies 101 at an optimum distance from each other. The omnidirectional wheels 104 have small discs or rollers around the circumference of the wheel 104 that are powered by the associated motor, enabling the wheels 104 to move in required direction, which provide the bodies 101 with the required movement in view of holding the door in a secured manner.

[0038] A temperature sensor associated with the bodies 101 detects significant change in temperature of the surroundings. The temperature sensor used herein, is composed of two type of metal wire joint together when the sensor experiences a heat then a voltage is generated in the two terminal of the temperature sensor that is proportional to the temperature and the signal is sent to the microcontroller. The microcontroller calibrates the voltage in terms of temperature from the received signal of the temperature sensor in order to monitor the temperature of surroundings of the bodies 101.

[0039] In accordance to the monitored temperature of the surroundings, multiple motorized suctions units attached with the bodies 101 are activated by the microcontroller for gripping the door, in account for thermal expansion or contraction of materials. The suction unit comprises a suction cup that is designed to hold the door with the bodies 101 tightly and operates by creating a vacuum seal between the bodies 101 and with the associated suction cup. Upon actuation by the microcontroller, the unit uses a pump to evacuate air from the space between the suction cup and the door's surface, creating negative pressure. This pressure differential causes atmospheric pressure to push the door firmly against the suction cup, creating a strong grip. The seal is maintained as long as the vacuum remains intact, securely holding the door in place for carrying the door installation process.

[0040] After holding the door, the material of the door is detected by a capacitance sensor which is embedded on one of the bodies 101 works in sync with the imaging unit 103. The capacitive sensor detects the material type of the accommodated door by measuring changes in capacitance caused by the door's material properties. It consists of two electrodes separated by a dielectric material (air in this case). When the door is placed over the bodies 101, the dielectric constant of the material affects the capacitance between the electrodes. Different materials (such as wood, metal, or glass) have varying dielectric constants, altering the capacitance detected by the sensor which are processed by the microcontroller.

[0041] In case the detected material type of the door corresponds to wood, the microcontroller actuates plurality of flaps 105 (ranging in between from 4 to 6 in numbers) for providing stability to the accommodated door. The flaps 105 are arranged over inner periphery of the body 101 by means of multiple motorized hinges 106 (ranging in between from 4 to 6 in numbers).

[0042] The motorized hinges 106 used herein, are piece of metal that joins the flaps 105 with bodies 101 together and allows the flaps 105 to be oriented by revolving along the longitudinal axis whose operation is governed by a DC motor, such that the hinges 106 position the flaps 105 on periphery of the door for stabilizing the door over the structure.

[0043] In case the microcontroller via the capacitance sensor detects the material type of the door to metallic material, the microcontroller energizes a pair of rectangular magnetic strips 107 which are configured on lateral sides of each of the bodies 101. The magnetic strips 107 consists of wire wound into a coil and a current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil. The magnetic field disappears when the current is turned off. The wire turns are wound around a magnetic core made from a ferromagnetic or ferromagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet, thereby the magnetic strips 107 grips the door in a secured manner.

[0044] Post stabilizing the door, the presence and exact location of door hinges 106 /latches over the door casing is detected by a LiDAR (Light Detection and ranging) sensor which is embedded on one of the bodies 101. The LiDAR sensor works in sync with the imaging unit 103. The LiDAR (Light detection and ranging) sensor emits a short laser pulse over the door casing where the door is needed to be installed and the laser further strikes to the hinges 106 /latches, creates a spot and reflects back which is captured by the LiDAR (Light detection and ranging) sensor. The signals are sent to the microcontroller for processing and on the basis of time lapse in between the sent and received laser pulse, the microcontroller determines position and location of the hinges 106 /latches.

[0045] In accordance to the detected location of the microcontroller regulates actuation of the wheels 104 for positioning and aligning the door in a manner to aid the user to install the door over the door casing.

[0046] The structure is equipped with a LDR (Light dependent resistor) for detecting intensity of light on the surroundings. The LDR comprises of a photodiode, wherein the photodiode is capable of measuring intensity of illuminance as when beam of light strikes the photodiode, then the photodiode have a tendency to loosen electrons causing an electric current to flow. More the intensity of light, stronger is the electric current generated by the sensor, such that the intensity of light in the surroundings is detected by the microcontroller.

[0047] In case the microcontroller detects the intensity of light with a threshold intensity of light needed to perform door installation operation, the microcontroller activates plurality of LED 108 (Light Emitting Diode) light (ranging in between from 4 to 6 in numbers). The LED 108 lights are integrated on both of the bodies 101 such that when activated illuminates the surrounding.

[0048] The LED 108 (Light Emitting Diode) light disclosed herein is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light is corresponding to the energy of the photons and is determined by the energy required for electrons to cross the band gap of the semiconductor thereby illuminates the surrounding which consequently improves the optimal intensity of light required to perform the operation for installation in the surroundings.

[0049] The present invention works best in the following manner, where the proposed invention includes the artificial intelligence-based imaging unit 103 detect exact location of the door, accordingly the microcontroller actuates the motorized omnidirectional wheel 104 for providing movement to the body 101 over ground surface in view of accommodating the door over horizontal base of the U-shaped body 101 . The sensing module detects dimensions and weight of the door, respectively, accordingly the microcontroller synchronously actuates the bars and body 101 to extend in upward direction for positioning apex of the structure at the optimum height, followed by actuation of the wheels 104 to positioning the bodies 101 at the optimum distance from each other, in view of holding the door in the secured manner.

[0050] In continuation, the capacitance sensor detects material type of the door and in case the material type of the door corresponds to wood, the microcontroller actuates plurality of flaps 105 and the motorized hinges 106 to provide tilting movement to the flaps 105 in order to position the flaps 105 on periphery of the door for stabilizing the door over the structure. In case material type of the door corresponds to metallic material, the microcontroller energizes the magnetic strips 107 for gripping the door in the secured manner. Then, the LiDAR (Light Detection and ranging) sensor detects presence and exact location of door hinges 106 /latches over the door casing, accordingly the microcontroller regulates actuation of the wheels 104 for positioning and aligning the door in the manner to aid the user to install the door over the door casing.
