Various examples of embodiments of the systems, devices, and methods according to this invention will be described in detail, with reference to the following figures.
It should be understood that the drawings are not necessarily to scale. In certain instances, details that are not necessary to the understanding of the invention or render other details difficult to perceive may have been omitted. It should be understood, of course, that the invention is not necessarily limited to the particular embodiment illustrated herein.
Within the scope of this application, it is expressly intended that the various aspects, embodiments, examples, and alternatives set out in the preceding paragraphs, and the claims and/or the following description and drawings, and in particular the individual features thereof, may be taken independently or in any combination. That is, all embodiments and all features of any embodiment can be combined in any way and/or combination, unless such features are incompatible. The applicant reserves the right to change any originally filed claim or file any new claim accordingly, including the right to amend any originally filed claim to depend from and/or incorporate any feature of any other claim although not originally claimed in that manner.
One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
As shown, the first back support 15 and the second back support 20 are separately connected to the seat support structure 25 of the chair 10. In one example, the first back support 15 and the second back support 20 are interconnected to one another at a common point or axis. Additionally, the second back support 20 is not connected to the seat support structure 25 via the first back support 15, nor is the first back support 15 connected to the seat support structure 25 via the second back support 20. The result of this arrangement makes the first back support 15 and the second back support 20 independently movable. An example of this arrangement is disclosed in U.S. Pat. No. 11,641,944, which is incorporated herein by reference. Any additional support arms for additional back supports may also be coupled to the seat support structure 25 such that the additional support arms rotate about the same or similar pivot axis.
The first support arms 30 and the second support arm 35 are independently movable such that the first back support 15 and the second back support 20 can move independently relative to each other through a broad range of motion. That is, the first support arms 30 and the second support arm 35 allow independent forward and backward movement of each of the first back support 15 and the second back support 20 relative to a seat 40 of the chair 10 by adjusting the angle of the respective the first support arms 30 and the second support arm 35. In some examples, to enable the independent forward and backward movement of the first back support 15 and the second back support 20, the first support arms 30 are offset from a center of the first back support 15 and positioned on either side of the second back support 20 so that the first support arms 30 and the second support arm 35 do not interfere with one another when the first back support 15 and the second back support 20 are adjusted. For the shown example, the first support arms 30 and the second support arm 35 are also shaped (e.g., curved, angled, etc.) to allow independent movement through a broad range of angles without interference.
Alternatively, a single support arm may be used for the first back support 15 and two offset support arms may be used for the second back support 20 and positioned on either side of the single support arm. In other examples, one support arm may be used for each of the first back support 15 and the second back support 20 and one or both of the support arms may be curved in a way to prevent interference while also contacting a center portion of each of the back supports. In further alternative examples, each of the back supports may be coupled to the seat support structure using multiple support arms.
Additionally or alternatively, each of the first back support 15 and the second back support 20 may be independently height adjustable. The example first and second support arms may be extendible to adjust the height of the respective first and second back supports.
While the first back support 15 and the second back support 20 in
In some examples, additional back supports (e.g., a neck support) may be connected to the seat support structure 25 via one or more additional support arms. In even further examples, aspects of the invention can be used in a singular seat back support combination.
The illustrated construction of
The shown chair 10 has the base 45. The shown base 45 includes a leg assembly 60 including four legs 65 and the piston assembly 50. The piston assembly 50 is height adjustable. A caster 67 or coaster may be attached to the end of each leg 65.
The piston assembly 50 couples the base 45 to the seat 40 at the seat support structure 25. In the construction shown, the seat support structure 25 supports a seat pan 70 holding a cushion 72, receives the first support arms 30 and the second support arm 35 supporting the first back support 15 and the second back support 20, and includes the mechanisms to aid in adjusting the chair 10 including the first back support 15 and the second back support 20.
The seat support structure 25 and the second support arm 35 are shown in
On the other end of the second support arm 35, for the shown construction, is a support arm neck 80. The support arm neck 80 helps couple the second support arm 35 to the second back support 20.
Between the support arm base and the support arm neck is the support arm body 85 (may also be referred to as the support column). The support arm body 85 is an arcuate upright shaft that supports the overhead structure of the second back support 20 via the support arm neck 80.
As best shown in
The shown support structure 120 includes guides 195, 200 to help place the first side 125 of the illumination and control assembly 115 within the channel 110 of the trough 105. The illumination and control assembly 115 can be secured to the support arm body 85 by fasteners 205, 210. In the shown construction, the fasteners are screws received by apertures.
On the second side 130 of the support structure 120, the first compartment 155 and the second compartment 175 help to define channels or spaces 215, 220 for receiving illumination strips 225, 230. For the example shown, the illumination strips 225, 230 include light emitting diodes (LEDs), which can be multiple colors. As will be discussed further below, the control board 180 controls the illumination strips 225, 230 to prove a scene.
Covering the second side 130 and the illumination strips 225, 230, is a cover 235. In the shown construction, the cover 235 includes a diffuser to help defuse the light emanating from the illumination strips 225, 230. The cover 235 may also be referred to as a diffuser cover. The diffuser can be a layer coupled with a cover layer (e.g., a clear cover). Additionally or alternatively, the diffuser may be integrated within the cover 235.
Included with cover 235 is a power connector 240. For the shown illumination and control assembly 115, the power connector 240 includes a magnetic breakaway power connector. Also included at the power connector 240 is a power supply 250, as will be discussed below.
A block diagram for the electrical elements of the chair 10 is provide in
The BMS and conditioning circuit 255 includes a battery management system (BMS) to control charge and discharge to the batteries 160, 170. The BMS and conditioning circuit 255 also includes conditioning circuitry that provides one or more battery voltages to the LDO circuit 265 and the illumination strips 225, 230. The illumination strips 225, 230 are shown in
The chair 10 also includes a power button 270 that can wake up or cause the chair 10 to sleep. The power button 270 can also be used to provide a signal to the controller 260 (via the BMS and conditioning circuit 255) to initiate a programming event.
The LDO circuit 265 is a low dropout (LDO) voltage regulator that provides a steady voltage to the controller 260 from the BMS and conditioning circuit 255. The BMS and conditioning circuit 255 also provides one or more DC voltages to the illumination strips 225, 230.
A level shifter circuit 275 controls the voltage provided to the illumination strips 225, 230 based on control or command signals from the controller 260. For example, the level shifter circuit 275 controls a voltage or current provided to the illumination strips 225, 230 and possibly groups of LEDs in the illumination strips 225, 230. Through the use of the level shifter circuit 275, the illumination strips 225, 230 can provide basic effects such as dimming/brightness, color selection, and flashing or intermittence. The controller 260 can build upon the basic effects to provide more complex color scenes such as chasing, waterfall, profiles or color schemes, etc. While a controller 260 and level shifter circuit 275 are shown, other illumination driving techniques for controlling the illumination strips 225, 230 can be used in alterative to the embodiment shown as is known by one skilled in the art.
The tag connect 280 and the debug header 285 allow for communication with the controller 260 for programming, debugging, and acquiring data to and from the controller 260 via a wired connection.
An antenna 290 allows for the controller 260, and more broadly the chair 10, to wirelessly communicate with an external electronic device. The external electronic device can be a user smart device or a network node. An example network node is a wireless local area network provided by a Wi-Fi network node.
The chair includes an accelerometer 295 on the control board 180 in communication with the controller 260. The accelerometer 295 senses movement of the chair 10 and provides a signal to the controller based on sensed movements. For example, a chair 10 movement indicates a person is present and the illumination strips 225, 230 can light in response to the movement of the chair 10. As another example, as being within the trough 105, the accelerometer 295 can sense movement of the second support arm 35, thereby indicating a user has set in the chair 10. It is also envisioned that the accelerometer 295 can be placed elsewhere. Additionally or alternatively, additional accelerometers can be added to other locations of the chair 10 and in communication with the controller 260 via the expansion header 300, and/or other sensor types can be added to the chair 10 and in communication with the controller 260 via the expansion header 300.
For the example shown, the controller 260 includes a processor 305 and a memory 310. It is contemplated that the processor 305 and memory 310 may each be a single electronic device or formed from multiple devices.
The processor 305 can include a component or group of components that are configured to execute, implement, and/or perform any of the processes or functions described herein for the chair 10 or a form of instructions to carry out such processes or cause such processes to be performed. Examples of suitable processors include a microprocessor, a microcontroller, and other circuitry that can execute software/firmware. Further examples of suitable processors include, but are not limited to, a core processor, a central processing unit (CPU), a graphical processing unit (GPU), an array processor, a vector processor, a digital signal processor (DSP), a field-programmable gate array (FPGA), a programmable logic array (PLA), an application specific integrated circuit (ASIC), math co-processors, and programmable logic circuitry.
The memory 310 includes memory for storing one or more types of instructions and/or data. The memory 310 can be a component of the processor, can be operatively connected to the processor for use thereby, or a combination of both.
In one or more arrangements, the memory 310 can include various instructions stored thereon. For example, the memory 310 can store one or more modules. Modules can be or include computer-readable instructions that, when executed by the processor, cause the processor to perform the various functions disclosed for the module. While functions may be described herein for purposes of brevity, it is noted that the functions for the chair are performed by the processor 305 using the instructions stored on or included in the various modules. One or more programs or modules may be stored in the memory for execution by the processor 305.
The memory 310 can include volatile and/or non-volatile memory. Examples of suitable memory include RAM (Random Access Memory), flash memory, ROM (Read Only Memory), PROM (Programmable Read-Only Memory), EPROM (Erasable Programmable Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), registers, disks, drives, or any other suitable storage medium, or any combination thereof. The memory 310 can be a component of the processor 305, can be operatively connected to the processor 305 for use thereby, or a combination of both.
Some modules may be stored remotely and accessible by the processor 305 using, for instance, various communication devices and protocols. One or more programs or modules may be stored in the memory 310 for execution by the processor 305.
Before proceeding, it should be understood by somebody skilled in the art that the controller 260 can includes many additional conventional elements typically found in a control system. Further discussion regarding these components is not provided herein since the components are conventional and their operation are conventional.
The chair 10 can communicate wirelessly (e.g., via a radio 315 coupled to the antenna 290) with a sever 320 or a mobile electronic device 325. An example of a radio 315 includes a wireless local area network (WLAN) radio and/or a cellular radio. The radio 315 can be a standalone circuit element or can be part of the controller 260. With a WLAN radio, the controller 260 generally communicates over a short-range wireless communication network 330. With a cellular radio, the controller 260 generally communicates over a cellular communication network (e.g., 4G, LTE, 5G, etc.). In one implementation, the radio 315 includes a communication controller, and a transceiver for transmitting and receiving signals to and from the chair 10 via the antenna 290.
The mobile electronic device 325 can be wirelessly directly coupled to the chair 10 and, alternatively or additionally, either the chair 10 or the mobile electronic device 325 can be coupled to the network 330, which can include the Internet among numerous other networks. The mobile electronic device 325 can communicate wirelessly (e.g., via its radio) with the sever 325.
The mobile electronic device 325 executes an application (or app), which is stored in memory of the electronic device as is well known. An application or app includes, but is not limited to, a software application. Generally, apps are available through app stores such as Apple's iTunes®, Google's Play Store®, Microsoft's App Store™, Blackberry®, and so forth. Apps are usually run on mobile-based operating systems running on iPhones®, iPads®, Android® Phones, Android® Tablets, Apple TV®, Google TV®, and many other similar devices, but can also be run on other operating systems, such as an operating system for a desktop computer. Some example operations related to the app are provided herein. The descriptions of the operations relate to their functionality are in terms of the app. This is intended to mean that the app is stored in the memory of the mobile electronic device 325 and includes processor-executable instructions that, when executed on the processor, cause the processor to perform the functionality described (in combination with other portions of the memory, as well as various hardware components of the electronic device (such as the user interface or the radio, for example)).
In one example operation, the chair 10 can operate the illumination strips 225, 230 in response to the accelerometer 295 sensing movement and/or input from the power button 270. The control of the illumination strips 225, 230 can be based on a program or profile in the memory 310 of the controller 260. The profile can be stored in the memory 310 via the antenna 290 receiving the profile from the external electronic device (e.g., the smart device) 325.
