Door handles and doorknobs are commonplace throughout the home. Typical handles and knobs are rotatable to selectively release a door latch, allowing a user to open a door. In the context of door handles positioned on doors within a building (e.g., residential premises, such as a house, apartment, or the like), such door handles may be positioned on doors that separate rooms for privacy or passage purposes. This includes separation of bedrooms from common areas, bathrooms, and the like.
It is often the case that individuals move within premises at night or when overhead lights are turned off. In such cases, individuals may try to navigate through premises without turning overhead lights on, e.g., to avoid disturbing others at night, or simply due to inconvenience of a light switch location. In these cases, individuals may have trouble determining the exact location of a door or door handle, leading the individual to fumble in darkness in an attempt to locate the door handle and open the door, allowing the individual to move among rooms within the premises.
In general, the present disclosure relates to a handle. In example embodiments, a handle includes a handle body and a removable cartridge. In examples, the cartridge includes a light-emitting diode, a sensor, and a battery. The light-emitting diode illuminates based on conditions sensed by the sensor.
In a first aspect, a door handle is provided. The door handle includes a handle body operatively attachable to a spindle of a handleset. The handle body has a grippable portion and, when installed at a door, is rotatable to move a latch between an extended position and a retracted position. The door handle further includes a cartridge positioned within an interior cavity of the handle body. The electronics cartridge includes a sensor circuit, a light-emitting diode, a battery and a release button. The light-emitting diode is configured to illuminate based on conditions sensed by the sensor circuit. The electronics cartridge is removable from the interior cavity of the handle body when the release button is pressed.
In a second aspect, an electronics cartridge for a door handle is provided. The electronics cartridge comprises a sensor circuit, a light-emitting diode, a battery, and a release button. The light emitting diode is configured to illuminate based on conditions sensed by the sensor circuit. The electronics cartridge is configured to be insertable into an interior cavity of a handle body of the door handle and removable from the interior cavity of the handle body.
In a third aspect, a method for changing a battery of an illuminating door handle is provided. The method includes pressing a release button of an electronics cartridge, removing the electronics cartridge including a first battery from an interior cavity of a handle body of the illuminating door handle, replacing the first battery with a second battery, and inserting the electronics cartridge into the interior cavity of the handle body.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
The following drawings are illustrative of particular embodiments of the present disclosure and therefore do not limit the scope of the present disclosure. The drawings are not to scale and are intended for use in conjunction with the explanations in the following detailed description. Embodiments of the present disclosure will hereinafter be described in conjunction with the appended drawings, wherein like numerals denote like elements.
Various embodiments of the present invention will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the invention, which is limited only by the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments for the claimed invention.
As used herein, “handle” can mean any object used for opening doors, cabinets, drawers, or similar barriers, including handles and knobs. The term “including” as used herein should be read to mean “including, without limitation,” “including but not limited to,” or the like. The term “substantially” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art (and is not to be limited to a special or customized meaning), and furthermore refers without limitation to being largely but not necessarily wholly that which is specified.
As briefly described above, embodiments of the present invention are directed to a door handle. In example embodiments, a door handle may include a light-emitting diode (LED). The LED may provide illumination to the handle, the door to which the handle is attached, or both. By providing this illumination, individuals will be able to identify the exact location of the door or door handle in low-light conditions. Accordingly, individuals may more easily move among rooms without needing to turn on overhead lights.
In some example aspects, the handle includes an interior cavity within the body of the handle, which may house electrical components. These electrical components may include an LED and a battery. By including the electrical components in the interior cavity, the handle is rotatable without the risk of damaging the electrical components or the wires connecting the electrical components.
In some example aspects, the interior cavity houses additional electrical components. This may include some combination of sensors in connection with the LED, such as light sensors or motion sensors. By incorporating sensors into the handle, the LED may be selectively illuminated, reducing the amount of energy consumed by the handle and extending the time before a battery would need to be replaced.

In the example shown, the handle body 26 has an interior cavity 28. As discussed in further detail below, the interior cavity 28 may be used to house electrical components. In an embodiment, the electrical components include a battery. In alternative embodiments, the electrical components can additionally include at least one of an LED, a light sensor circuit, a printed circuit board, a controller, a motion sensor, and a wireless network interface. Additional electrical and non-electrical components may also be housed in the interior cavity 28.

In the example shown, the handle 200 includes electrical components. The electrical components cooperate to selectively produce light that may illuminate the handle 200 and/or a door to which the handle 200 is mounted. In the depicted embodiment, the electrical components may include a battery 220 positioned within the interior cavity 204. The electrical components may further include, for example, an LED, as well as a light sensor circuit, and a printed circuit board (discussed in further detail below in conjunction with
As shown in
As discussed further below, in operation, when a light sensor circuit detects that the ambient light is below a set threshold, it may activate the LED for at least a period of time, causing the LED to turn on to emit light. This light is emitted through the at least semi-translucent cover 210 and may illuminate the handle 200 and/or the door. In further embodiments, the LED and the cover 210 may be configured such that substantially all of the cover 210 is illuminated by the LED. Additionally, a light filter may be included to change the color of the light projected or to project a pattern.
In the illustrated embodiment, the cover 210 extends out from the elongated portion of the handle body 202. With the LED housed in a compartment 212 in the cover 210, the LED can emit light in multiple directions, including toward the door and away from the door. The cover 210 is removable to allow access to the opening and any electrical components housed in the interior cavity 204. The cover 210 has an appendage 214 with an indentation 216 that slides into a second cavity 209 in the handle body 202 to interact with a bridge 207 across to an opening 208 of the second cavity 209. The appendage 214 is at least partially flexible, allowing it to recess into the second cavity 209 entirely beneath the bridge 207 as is slides along the second cavity 209. Once enough of the appendage 214 slides past the bridge 207 that the indentation 216 on the appendage 214 aligns with the bridge 207, the appendage 214 flexes back to its original orientation, engaging the bridge 207 in the indentation 216. The engagement between the bridge 207 and the indentation 216 removably attaches the cover 210 to the handle body 202. Applying pressure to the appendage 214 (e.g., downward force at the opening 208, and outward force away from the handle body 202 in a direction toward the end of the handle 200) may force it to recess back into the second cavity 209 entirely beneath the bridge 207, allowing the appendage 214 to slide along the length of the second cavity 209 so that the cover 210 may be removed. In alternative embodiments, different constructions of the cover 210 and/or handle body 202 may be used to attach the cover 210 to the handle body 202.

In the illustrated embodiment, the opening 406 to the interior cavity 404 is on multiple faces of the elongated portion of the handle body 402. The opening 406 to the interior cavity 404 may be on a face of the handle body 402 that faces toward a door (e.g., door 10) to which the handle 400 is attached and on a face on the end of the elongated portion of the handle body 402 away from the axis of rotation of the handle body 402. In this embodiment, light emitted from the LED shines through the cover 410 and can project onto the door. Light emitted from the LED can also shine through the cover 410 and out of the opening 406 on the face on the end of the elongated portion away from the axis of rotation of the handle body 402.

The screwing of the cover 510 to the handle body 502 can also be used to act as a switch that controls the operability of the electrical components 520 of the door handle 500. By screwing the cover 510 to a position such that the threads 511 of the cover 510 and the threads 505 of the opening 506 are engaged to attach the cover 510 to the handle body 502 without having the cover 510 screwed in entirely, the electrical connection between the battery 220 in the interior cavity 504 and the electrical components 520 in the compartment of the cover 510 may be disconnected, stopping operation of the electrical components 520 of the door handle 500. Additionally, different rotational positions of the cover 510 relative to the handle body 502 may initiate different functionality (e.g., controlling a color of light emitted, controlling an amount of time an LED remains active, and the like). In the example shown, a spring 521 biases the battery 220 toward the electrical components 520 to maintain electrical connection when the cover 510 is in place at the end of the handle body 502.

A light sensor circuit 802 controls a control element that opens and closes a connection to an LED 804. In an embodiment, the light sensor circuit 802 includes a photoresistor and the control element is a transistor 806. When photons of light hit the base of the photoresistor, the photoresistor produces an electrical signal. This signal causes the transistor 806 to trigger, closing the connection between the battery 220 and the LED 804, causing the LED 804 to emit light. In alternative embodiments, the light sensor circuit 802 and the control element can include additional or alternative elements that allow for similar function of the circuit 800 as a whole.

In the particular examples shown,
In an embodiment, a motion sensor is placed at just one of these possible locations 902-912. In alternative embodiments, the door handle includes multiple motion sensors which can be placed at a combination of the possible locations. In further embodiments, a motion sensor may be placed in a position not described above that allows for similar functionality.
In the depicted embodiment, the battery 220 provides power for the other electrical components. The controller 1002 controls the LED 1004 based on signals it receives from the other electrical components, including the light sensor circuit 1006, the motion sensor 1008, and a possible door sensor 1010. A signal from the light sensor circuit 1006 may cause the controller 1002 to transition the LED 1004 between an active state and an inactive state. The active state corresponds to a timing at which the controller 1002 may cause the LED 1004 to turn on to emit light. Additionally, a signal from the light sensor circuit 1006 indicating high or low levels of ambient light may cause the controller 1002 to change the brightness of the LED 1004. The controller 1002 may turn the LED 1004 on in response to a signal from the motion sensor 1008 indicating that a user is approaching the door handle. The controller 1002 may leave the LED 1004 on for as long as the motion sensor 1008 detects movement in a detection zone. Alternatively, the controller 1002 may leave the LED 1004 on for a preset amount of time after motion is detected. A signal from the door sensor 1010 indicating that the door is open may cause the controller to not turn on the LED 1004, even if other signals from other electrical components send signals that would normally cause the controller 1002 to turn on the LED.
Additionally, the controller 1002 may control the LED 1004 based on configured settings stored in the controller 1002. These settings may be received or changed through the wireless network interface 1012 or through a switch on the handle. These settings may cause the controller 1002 to adjust various characteristics of the light emitted by the LED 1004, including the color of the light, the intensity of the light, and the temperature of the light. The settings may also cause the controller 1002 to control the length of time that the LED 1004 emits light while the LED 1004 is in the active state. For example, the controller 1002 may include a timer that causes the LED 1004 to be on for a set amount of time while in the active state. A timer could also be used to cause the controller to turn the LED 1004 on at a certain time of day. The time of day at which the LED 1004 is turned on could be updated based on the time of year, with the LED 1004 being turned on at an earlier time of day when sunset is earlier in the day.
The controller 1002 may also control the LED 1004 based on various other conditions. For example, the controller 1002 may change color of the light emitted by the LED 1004 or may cause the LED 1004 to blink to indicate that a room is occupied or available. The controller 1002 may also cause the LED 1004 to change color or blink to indicate that the battery in the door handle is below a threshold amount of charge remaining.
The mobile device 1150 may display a graphical user interface through which a user may change a variety of settings for a door handle 1102a-n. The settings may apply to an individual door handle or multiple door handles associated with the user. These settings may change characteristics of the LED, including the duration of light emitted, the color of the light emitted, the intensity of the light emitted, and the temperature of the light emitted. The settings may also change the length of time that the LED emits light, either as a set length of time or by setting a time of day during which the LED is on. The settings may further turn the entire door handle system off, or they may turn off individual sensors included in the system. As the user changes settings in the graphical user interface, the mobile device 1150 sends the updated settings to the home automation controller 1104, either directly or through a user account associated with the door handles 1102a-n at remote server 1106. The home automation controller 1104 then pushes the updated settings to any door handle 1102a-n that had its settings changed.

In the example shown, the method 1200 includes the door handle receiving settings from a home automation system (step 1202). The door handle may be in communication with the home automation system via Bluetooth, Zigbee, Z-wave, or another low power wireless communication protocol. The settings received from the home automation system may be settings configured by a user, or they may be default settings. These settings may change characteristics of the LED, including the color of the light emitted, the intensity of the light emitted, and the temperature of the light emitted. The settings may also change the length of time that the LED emits light while the LED is in an active state, either as a set length of time or by setting a time of day during which the LED is on if the LED is in an active state. The settings may further turn the entire door handle system off, or they may turn off individual sensors included in the system.
In the example shown, the method 1200 includes a light sensor circuit in the door handle detecting ambient light levels (step 1204). The ambient light levels may be assessed relative to a particular threshold. Based on the determined light level, an LED of the door handle is selectively illuminated, based at least in part on the amount of ambient light detected (step 1206). If the amount of ambient light detected is below a threshold, the LED is put into the active state. If the amount of ambient light is above the threshold, the LED is put into the inactive state. The LED is operated according to the settings received from the home automation system (step 1208). That is, a controller at the door handle may determine to, based on particular settings, illuminate an LED for the entire period in which a particular light level is detected, or for only a portion of that time.
In some examples of the method 1200 certain steps may be excluded. For example, a controller may be preprogrammed with particular settings, and may not include a wireless communication interface. In such embodiments, no receipt of updated settings from a home automation system may occur. Rather, the preprogrammed settings may be used to assess times during which the LED is to be illuminated. Other configurations are possible as well.

The interior cavity 1304 may have an opening to allow access to the components stored within it. As discussed above with respect to door handles, the handle 1300 may also include an at least semi-translucent cover to substantially enclose the interior cavity and the components. The opening to the interior cavity and the at least semi-translucent cover may be on a face of the handle body 1302 that faces away from the front panel 1310, or they may be on a face of the handle body 1302 that faces toward the front panel 1310. The opening and the cover may additionally be on a face of the handle body 1302 that faces in a different direction.
As in previous embodiments, the electrical components associated with the handle 1300 cooperate to selectively produce light that may illuminate the handle 1300 and/or the front panel 1310. The electrical components may include an LED, a light sensor circuit, and a printed circuit board. In alternative embodiments, additional electrical components may be included. In embodiments, the printed circuit board is electrically connected to the other electrical components, and the power source provides power for the components. The light sensor circuit monitors for ambient light. When the light sensor circuit detects that the amount of ambient light is below a set threshold, it transitions the LED into an active state. While the LED is in the active state, the LED may turn on to emit light. This light is emitted through the at least semi-translucent cover and may illuminate the handle 1300 and/or the front panel 1310. In further embodiments, the LED and the cover may be configured such that substantially all of the cover is illuminated by the LED.

The handle 1400 has electrical components, as previously described. However, relative to those previous embodiments, in the example shown, the handle 1400 includes an at least semi-translucent cover (e.g., in place of cover 210, 310, 410, etc.), which has an at least semi-opaque decorative pattern 1424. When light from the LED is emitted through the cover, the decorative pattern 1424 is projected onto the door. In an alternative embodiment, a filter with an at least semi-opaque decorative pattern 1424 is used. When light from the LED is emitted through the filter, the decorative pattern 1424 is projected onto the door. In an embodiment, the filter is inserted between the LED and the cover. In an alternative embodiment, the filter is attached outside of the cover. Additionally, filters can be used to change the color of the light projected.

In the example shown, the electronics cartridge 1504 further includes a sensor 1508. The LED 1506 is configured to illuminate based on conditions sensed by the sensor 1508. In an embodiment, the sensor 1508 includes an ambient light sensor. In such an embodiment, the LED 1506 is configured to illuminate when the ambient light registered by the sensor 1508 is below a threshold—e.g., when it is sufficiently dark around the handle 1500. In some embodiments, the sensor 1508 includes a motion sensor. In such an embodiment, the LED 1506 is configured to illuminate when the sensor 1508 detects a user approaching the handle 1500. In further embodiments, the sensor 1508 includes both an ambient light sensor and a motion sensor. In these embodiments, the LED 1506 is configured to illuminate when a user approaches the handle 1500 and the ambient light is below a threshold. In the illustrated embodiment, the sensor 1508 is positioned on an end face 1534 of the handle 1500. In alternative embodiments, sensor 1508 may be positioned on different faces of the handle 1500. In some embodiments, in which the sensor 1508 includes an ambient light sensor and a motion sensor, the ambient light sensor may be positioned on a different face of the handle 1500 than the motion sensor.
In further embodiments, the electronics cartridge 1504 includes further electronic components. For example, the electronics cartridge 1504 may include a wireless network interface (e.g., as described above in connection with
The electronics cartridge 1504 includes a battery 220, which provides power to electronic components of the electronics cartridge 1504, including the LED 1506 and the sensor 1508. In the illustrated embodiment, the electronics cartridge 1504 includes one or more battery clips 1530, which retain the battery 220 in the electronics cartridge 1504. In examples, the battery clips 1530 help the battery 220 maintain an electrical connection with the electronics cartridge 1504 by substantially preventing the battery 220 from unintentionally moving. In an example embodiment, the battery 220 is an alkaline battery. In further examples, the battery 220 is a different type of battery, as described above. While the illustrated embodiment shows a single battery 220 in the electronics cartridge 1504, in alternative embodiments, the electronics cartridge 1504 may be configured to include multiple batteries.
In the illustrated embodiment, the electronics cartridge 1504 is insertable into the handle body 1502 in a longitudinal direction, e.g., from an end of the handle body 1502 in a direction toward a spindle-engaging portion of the handle body. As shown, the electronics cartridge 1504 includes ramps 1514 which engage with retaining notches 1512 on the handle body 1502 to maintain a connection between the electronics cartridge 1504 and the handle body 1502 (best shown in
The electronics cartridge 1504 further includes an edge 1536 which engages with a front wall 1522 on the outer face 1532 of the handle body 1502 to prevent the electronics cartridge 1504 from being inserted too far into the cavity 1528. The electronics cartridge 1504 may additionally or alternatively have a length such that a back end 1538 of the electronics cartridge 1504 engages an internal wall 1540 of the handle body 1502 to prevent the electronics cartridge 1504 from being inserted too far into the cavity 1528.
A release button 1510 can be pressed to separate the faces of the ramps 1514 from notches 1512, thereby disengaging a mechanical latching mechanism retaining the electronics cartridge 1504 within the handle body 1502. Upon releasing this latching mechanism, the electronics cartridge 1504 may be manually removed from the handle body 1502. The electronics cartridge 1504 can be removed, for example, to replace a battery 220. In an embodiment, the ramps 1514 are connected to, or integrally formed with, the release button 1510 such that pressing the release button 1510 moves the ramps 1514 into the cavity 1528, disengaging the ramps 1514 from the notches 1512. While the ramps 1514 are disengaged from the notches 1512, the electronics cartridge 1504 can slide along the length of the handle body 1502 out of the cavity 1528.
In some embodiments, the release button 1510 is coupled with a button spring 1518 (best shown in
In the illustrated embodiment, the release button 1510 is positioned such that an outer face 1524 of the release button 1510 is substantially flat, or coplanar, with an inner face 1542 of the handle body 1502 when the electronics cartridge 1504 is engaged with the handle body 1502. In an embodiment, the release button 1510 includes a tab 1526 that extends out from the interior cavity 1528 and past the inner face 1542 of the handle body 1502, allowing easier access to the release button 1510 (best shown in
In alternative embodiments, the release button 1510 may be smaller, such that the outer face 1524 of the release button 1510 does not extend out to be substantially flat with the inner face 1542 of the handle body 1502 and is instead positioned recessed from the inner face 1542 toward the main body of the electronics cartridge 1504. Other methods may additionally or alternatively be used to recess the outer face 1524 of the release button 1510 behind the inner face 1542 of the handle body 1502. For example, the button spring 1518 may be smaller such that the button spring 1518 does not bias the release button 1510 as far outward.
In an example, when the outer face 1524 of the release button 1510 is positioned behind the inner face 1542 of the handle body, a finger may be unable to press the release button 1510, and a tool may be necessary to press the release button 1510. By recessing the outer face 1524 of the release button 1510 behind the inner face 1542, the release button 1510 is less likely to be accidentally pressed, and the electronics cartridge 1504 is less likely to be accidentally removed from the handle body 1502. Security may additionally be increased as an unauthorized user may be prevented from removing the electronics cartridge 1504 if the unauthorized user does not have the tool to press the release button 1510.
In the illustrated embodiment, the electronics cartridge 1504 includes a cartridge spring 1516. The cartridge spring 1516 is positioned to bias the electronics cartridge 1504 in a direction opposite the direction of insertion of the electronics cartridge 1504 into the cavity 1528. In the example shown, the cartridge spring 1516 is compressed when the electronics cartridge 1504 is fully inserted into the handle body 1502. When the release button 1510 is pressed and the electronics cartridge 1504 can freely slide out of the cavity 1528, the cartridge spring 1516 applies a biasing force to separate the electronics cartridge 1504 in the direction opposite the insertion direction, thereby assisting in removing the electronics cartridge 1504 from the cavity 1528. The cartridge spring 1516 may additionally provide a force outwardly on the electronics cartridge 1504 while the electronics cartridge 1504 is inserted into the handle body 1502. The force may help the ramps 1514 maintain engagement with the notches 1512.
In an embodiment, the electronics cartridge 1504 includes a rib 1520 that rubs against the front wall 1522 of the handle body 1502 as the electronics cartridge 1504 is removed from the cavity 1528. The friction caused by the rib 1520 substantially prevents the biasing force imparted by the cartridge spring 1516 on electronics cartridge 1504 from entirely expelling the electronics cartridge out of the cavity 1528. Rather, the electronics cartridge 1504 may “pop” out from the handle body 1502 partially, allowing the user to subsequently slide the electronics cartridge a remaining amount out of the cavity 1528.
In the illustrated embodiment, the cartridge spring 1516 is included on the electronics cartridge 1504. In alternative embodiments, the cartridge spring 1516 is included in the handle body 1502. In some embodiments, the handle 1500 does not include the cartridge spring 1516. In such embodiments, a user pulls the electronics cartridge 1504 the entire way out of the cavity 1528.
