The invention is capable of other embodiments and of being practiced or of being carried out in various ways.

[0024] To avoid crowding the drawings with reference numbers for different ends, sides, etc. of parts of the table, it will be presumed that one of ordinary skill will read this disclosure with the ordinary meaning of directional and positional terms in mind. Throughout this disclosure, for example, the terms “left,” “right,” “rear,” “front,” “forward,” and “rearward” are used from theperspective of an occupant or user at the table. Terms such as “top” and “bottom” are used with respect to the intended ordinary condition of the table. The term “above” means that one component is positioned higher than another without necessarily being in the same vertical plane. The term “vertically above” means that one component is higher than another thing and in the same vertical plane. “Below” means a component is lower than another component, whereas “vertically below” means that the component is lower and also within the same vertical plane as the other component.

[0025] FIG. 1 illustrates a table 10, or desk, to support computers, lights, and other accessories. The table 10 includes a worksurface 14, height adjustable legs 18 extending form the worksurface 14, and feet 22 coupled to ends of the legs 18 to support the table 10 on a floor or other surface. The illustrated table 10 is a height adjustable table configured to adjust the height of the worksurface 14 relative to the ground. As such, the legs 18 include a movable portion (e.g., a column) within a support and an actuator 24 (FIG. 8) that is operable to move the moveable portion relative to the support to adjust the height of the table 10. In other embodiments, the height of the worksurface 14 may be moveable in other ways. The illustrated table 10 includes two legs 18, but may alternatively include fewer or more legs, such as a single leg or four legs. Additionally, the worksurface 14 may have other configurations (e.g., shapes and / or sizes).

[0026] The table 10 also includes a control device 26 coupled to the worksurface 14 to adjust the height of the worksurface 14 and other features of the table 10. In the illustrated embodiment, the control device 26 is coupled to a bottom side of the worksurface 14 adjacent a front side where a user would generally sit when at the table 10. In other embodiments, the control device 26 may be coupled to the table 10 at other locations. For example, the control device 26 may be coupled to a top side of the worksurface 14, be positioned within the worksurface 14, coupled to one of the legs 18, or coupled elsewhere on the table 10.

[0027] With reference to FIGS. 2-4, the control device 26 includes a mount or frame 30, a user interface 34 supported by the frame 30, and a connector 38. The frame 30 includes a first portion 42 and a second portion 46 extending at an oblique angle to the first portion 42. The first portion 42 includes fastener openings 50 (FIG. 3) on a top side that are operable to receivefasteners to couple the control device 26 to the worksurface 14. The second portion 46 defines a cavity 54 (FIG. 4) to receive the user interface 34. The user interface 34 includes a display 58 that a user can interact with to control operation of the table 10. In the illustrated embodiment, the display 58 is generally rectangular. In other embodiment, the display 58 may be other shapes such as square, triangular, circular, etc. The connector 38 connects the user interface 34 to a power hub 62 (FIG. 8), both physically and electrically, to provide power to the user interface 34 and allow communication between the power hub 62 and the user interface 34.

[0028] With reference to FIG. 4, the user interface 34 includes a rotatable knob 66 or switch, a faceplate 70, an adhesive layer 74, a display screen 78, a positioning bracket 82, and a circuit board 86. The knob 66 includes a base 90 and a cap 94 supported by the base 90. In some embodiments, the base 90 and the cap 94 are formed as an integral component. In other embodiments, the base 90 and the cap 94 are formed as separate components. The base 90 may be made of a light-transmissive material, such a polycarbonate. As such, the base 90 may form a light pipe. The cap 94 includes a pattern of transparent portions 98 on a front side that allows light coming from within the cavity 54 of the frame 30 to extend through the transparent portions 98. In some embodiments, the transparent portions 98 may be openings that extend through the cap 94. In other embodiments, the transparent portions 98 may include a film such as glass or plastic to allow light to pass. Referring to FIG. 7, the pattern of transparent portions 98 may vary. For example, the pattern of transparent portions 98 may define a crosshair pattern, rings, logos, initials, etc. As such, the knob 66 and / or cap 94 may be interchangeable with other knobs 66 and / or caps with different patterns of transparent portions 98. In some embodiments, the cap 94 may be made through an additive manufacturing process such as 3D printing or the like. In further embodiments, the cap 94 may be made from a soft textured material such as thermoplastic polyurethane or the like.

[0029] With reference back to FIG. 4, the faceplate 70, the adhesive layer 74, and the positioning bracket 82 each include a circular opening 102 that receives the knob 66. The faceplate 70 is made from a transparent material such as glass, plastic or the like. The adhesive layer 74 is positioned between the positioning bracket 82 and the faceplate 70 and includes a second opening 106 that receives the display screen 78. The adhesive layer 74 includes an adhesive on both sides to couple the faceplate 70 to the positioning bracket 82. The adhesivelayer 74 also inhibits the faceplate 70 from contacting the display screen 78 and the positioning bracket 82 to prevent the positioning bracket 82 from scratching the faceplate 70 or the display screen 78. The positioning bracket 82 includes a recess 110 that receives and supports the display screen 78. In the illustrated embodiment, the display screen 78 is a 1.3 inch black / white organic light emitting diode (OLED) screen. In other embodiments, the display screen 78 may be other sizes and types of screens. For example, the display screen 78 may be an liquid crystal display (LCD) screen and / or a color screen. The display screen 78 is configured to display the height of the worksurface 14 relative to the ground. The display screen 78 is also configured to display other displays as will be discussed in more detail below. With reference to FIG. 3, an annular ring 114 of the base 90 is exposed between the faceplate 70 and the cap 94. The annular ring 114 allows light to pass from within the cavity 54 of the frame 30.

[0030] Referring to FIGS. 5 and 6, the circuit board 86 includes a rotary encoder 118 or a switch, a light source 122, and a controller 126 (FIG. 8). The rotary encoder 118 includes a base 130 coupled to the circuit board 86 and a stem 134 extending from the base 130. The stem 134 is coupled to the knob 66 for rotation therewith. The stem 134 and the knob 66 are operable to continuously rotate 360 degrees about a rotation axis 138 to adjust the height of the worksurface 14. The stem 134 and knob 66 are also depressible axially relative to the base 130 along the rotation axis 138. The rotary encoder 118 may include a disc with a plurality of detents. The detents provide haptic feedback (e.g., clicks) to a user as the user rotates the knob 66. Rotation of the knob 66 between adjacent detents define a first incremental amount of movement for the rotary encoder. In addition, rotation of the knob 66 between adjacent detents corresponds to a second incremental amount of change in the height of the worksurface 14. Meanwhile, rotation of the knob 66 between adjacent detents provides the user with haptic feedback for the incremental change of the worksurface 14. In the illustrated embodiment, the light source 122 is a red green blue (RGB) light emitting diode (LED) that can produce a broad spectrum of colors (e.g., red, blue, green, yellow, orange, etc.). In other embodiments, the light source 122 may be other types of LEDs or lights. The light emitted by the light source 122 extends through the light pipe and the transparent portions 98 of the knob 66 and is viewable by a user. In the illustrated embodiment, the circuit board 86 includes a single light source 122. In other embodiments, the circuit board 86 may include more than one light source. Further, the light source 122 is aseparate light source than any light the display screen may produce. The controller 126 is in electrical communication with the rotary encoder 1 18, the display screen 78, and the light source 122 as described below.

[0031] FIGS. 8 and 9 illustrate schematic views of a control system 142 to control operation of the table 10. The control system 142 includes the power hub 62, the user interface 34, a plurality of lights or light strips 146 that are supported on the table 10, a controller 150 for the light strips 146, and the actuator 24 (e.g., motor) for each of the legs 18. The controller 150 is electrically connected to the light strips 146 to control operation of the light strips 146. In some embodiments, the light strips 146 may be supported on a bottom side of the worksurface 14 to illuminate the area underneath the worksurface 14. In other embodiments, the light strips 146 may be supported along the legs 18 or the edges of the worksurface 14. In further embodiments, the light strips 146 may not be supported by the table 10, but may be located adjacent the table 10. The light strips 146 may include a plurality of RGB LEDs similar to the light source 122 discussed above. The plurality of LEDs may be arranged in a single row or in an array.

[0032] As mentioned above, the user interface 34 is electrically connected to the power hub 62 through the connector 38. Similarly, the controller 150 is electrically connected to the power hub 62 through a similar connector 38. In addition, each of the motors 24 of the legs 18 are connected to the power hub 62 through a connector 38. As such, the user interface 34, the controller 150, the power hub 62, and each of the motors 24 are in communication with each other. In other words, the user interface 34, the controller 150, the power hub 62, and each of the actuators 24 are configured to send signals between each other. In the illustrated embodiment, the power hub 62 is a local interconnect network (LIN) bus that receives power from an outside power source 154 (e.g., a battery or electrical wall outlet) through an AC / DC converter. In general, the controller 126 is configured to receive a user input from the rotary encoder 118 when the knob 66 is rotated or depressed and send a signal to the power hub 62. Depending on the input, the power hub 62 relays that signal to the actuators 24 to change the height of the worksurface 14 or to the controller 150 to change a parameter of the light strips 146 such as the color or brightness as will be described in more detail below.

[0033] The controllers 126, 150 may be implemented as microprocessors. In other embodiments, the controllers 126, 150 may be implemented as microcontrollers (with memory on the same chip). In other embodiments, the controllers 126, 150 may be implemented using multiple processors. In addition, the controllers 126, 150 may be implemented partially or entirely as, for example, a field-programmable gate array, an application specific integrated circuit (ASIC), and the like, and the memory may not be needed or be modified accordingly. The memory may include non-transitory, computer readable memory that stores instructions that are received and executed by the controllers 126, 150 to carry out functionality of the table 10 described herein. The memory may include, for example, a program storage area and a data storage area. The program storage area may include combinations of different types of memory, such as read-only memory and random-access memory.

[0034] While using the table 10, a user may interact with the user interface 34 to adjust the height of the table 10 or parameters of the light source 122 and light strips 146. To change the height of the table 10, a user may rotate the knob 66 in a first direction (e.g., clockwise) to raise the height of the worksurface 14. Alternatively, a user may rotate the knob 66 in a second direction (e.g., counterclockwise) opposite the first direction to lower the worksurface 14. As the knob 66 is rotated, the detents provide haptic feedback to the user. Additionally, as the knob 66 is rotated between adjacent detents, the rotary encoder 118 communicates a signal to the controller 126 to raise or lower the worksurface 14 in a fine increment. For example, rotation of the knob 66 between adjacent detents increases or decreases the height of the table 10 by 0.1 inches, 1 centimeter, or 2 millimeters. In other words, rotation of the knob 66 between adjacent detents increases or decreases the height of the table an incremental amount. In other embodiments, the incremental amount may be within a range between 0.05 inches and 0.5 inches. Further, the incremental amount may be within a range between 0.1 inches and 0.25 inches. As the knob 66 is rotated between adjacent detents, the controller 126 sends a signal to the power hub 62 which then relays the signal to the actuators 24 of the legs 18 to raise or the lower the worksurface 14 the determined increment. Meanwhile, as the knob 66 is rotated between adjacent detents, the controller 126 communicates to the display screen 78 to change the height displayed on the display screen 78 in fine increments (e.g., change from 28.1 inches to 28.2 inches or from 713 millimeters to 716 millimeters). The user can rotate the knob 66 untilthe worksurface 14 is at a desired height or until the display screen 78 displays the desired height of the worksurface 14. In some embodiments, there may be a delay between when the user rotates the knob 66 and when the power hub 62 sends a signal to the motors 24 to lift the worksurface 14. In the illustrated embodiment, the worksurface 14 may be moved within a range from 24 to 35 inches or 610 to 889 millimeters. In other embodiments, the worksurface 14 may be moved within a range between 24 to 47 inches or 610 to 1194 millimeters.

[0035] FIGS. 10-14 illustrate the operation of the user interface 34 between the use of the knob 66 and the display screen 78. With reference to FIG. 10, rotating or depressing the knob 66 illuminates and turns on the display screen 78 which displays the current height of the table 10. A user can depress the knob 66 once to change the display screen 78 to a settings screen. Once in the setting screen, the user can rotate the knob 66 to move between a plurality of menu screens (e g., Al, Bl, Cl, DI). As shown, the plurality of menu screens includes a lighting screen Al, a preset screen Bl, a units screen Cl, and a home menu screen DI. Depressing the knob 66 while on one of the menu screens will move to an adjustment screen (e.g., A2, B2, C2) where a user can adjust the settings of the table 10. Depressing the knob 66 while on the lighting screen Al will change the display screen 78 to a first adjustment screen A2, depressing the knob 66 while on the presets screen Bl will change the display screen 78 to a second adjustment screen B2, depressing the knob 66 while on the units screen Cl will change the display screen 78 to a third adjustment screen C2, and depressing the knob 66 while on the home screen DI will change the display screen 78 back to display the height of the table 10.

[0036] With reference to FIG. 11, while the display screen 78 displays the first adjustment screen A2, rotation of the knob 66 cycles a selector icon 158 between a color slide icon 162, a brightness slide icon 166, a solid color icon 170, and a return icon 174. When the selector icon 158 is on the desired icon, a user may depress the knob 66 to adjust the setting. Rotation of the knob 66 after selecting the color slide icon 162 adjusts the colors of the light source 122 and the light strips 146. As the knob 66 is rotated, the rotary encoder 118 sends a signal to the controller 126 which sends a signal to the power hub 62. The power hub 62 then communicates that signal to the controller 150 of the light strips 146 to change the color of the light strips 146 based on the user input. In other embodiments, the controller 150 can be electrically connected to the user interface 34 allowing the controller 126 to send a signal to the controller 150 of the light strips146 to change the color of the light strips 146. Similarly, the controller 126 communicates the signal to the light source 122 to change the color of the light source 122 based on the user input. The light source 122 will then emit that color light through the transparent portions 98 of the knob 66 and the annular ring 114. The light source 122 and the light strips 146 may be changed between a wide array of colors on the color spectrum. In the illustrated embodiment, the light strips 146 and the light source 122 emit the same color. In other embodiments, the light strips 146 and the light source 122 may emit different colors. Rotation of the knob 66 after selecting the brightness slide icon 166 changes the brightness of the light strips 146 and the light source 122 in a similar manner as described above. Rotation of the knob 66 after selecting the solid color icon 170 cycles the light source 122 and the light strips 146 between a variety of preset colors (e.g., red, blue, green). After the desired setting of the light strips 146 and light source 122 is selected, a user can depress the knob 66 to save the setting and exit the first adjustment screen A2.

[0037] With reference to FIG. 12, while the display screen 78 displays the second adjustment screen B2, rotation of the knob 66 cycles the selector icon 158 between three preset icons (i.e., Pl, P2, P3) and the return icon 174. When the selector icon 158 is on any of the preset icons, depressing the knob 66 will change the display screen 78 to a save screen B3. While the save screen B3 is displayed, a user can rotate the selector icon 158 between “yes” and “no” icons. Depressing the knob 66 when on the “yes” icon will save the current height of the worksurface 14 as a preset setting that is selectable to a user as described below. The preset setting is then saved in the memory of the controller 126. In addition, depressing the knob 66 when on the “yes” icon or the “no” icon will return the display screen 78 back to the second adjustment screen B2.

[0038] Referring to FIG. 13, to select one of the preset settings a user can depress and hold the knob 66. After a duration of time (e.g., two seconds), one of the preset icons will appear on the display screen 78. If a user continues to depress the knob 66 for an additional predetermined duration of time (e.g., one second), another of the preset icons will appear on the display screen 78. As the user continues to depress the knob 66, the display screen 78 will cycle through all the preset icons. When a user is on a desired preset icon, releasing the knob 66 will change the display screen 78 to a prompter screen El . When the prompter screen El is displayed, the usercan rotate the knob 66 to cycle the selector icon 158 between an icon to choose the preset setting or cancel. If the user chooses the preset setting, the controller 126 of the user interface 34 will communicate to the motors 24 via the power hub 62 to adjust the height of the worksurface 14 to the selected preset setting. If the cancel icon is selected, the display screen 78 will return to the height display. If the knob 66 is depressed for an extended predetermined time period (e.g., ten seconds) the display screen 78 will display a reset screen Fl. Then, the user can cycle the selector icon 158 between “yes” and “no” icons to decide whether to reset the user interface 34 back to default settings.

[0039] Referring to FIG. 14, while the display screen 78 is on the third adjustment screen C2, rotation of the knob 66 cycles the selector icon 158 between two units icons and the return icon 174. A toggle 178 illustrates what the current displayed unit is set to. Depressing the knob 66 on one of the units icons will set the display screen 78 to display the height of the worksurface 14 in that unit. In the illustrated embodiment, the display screen 78 can display the height of the worksurface 14 in either inches or centimeters. After using the user interface 34, the display screen 78 will turn off after a predetermined time of inactivity.

[0040] Providing a height adjustable table with a user interface provides a user with controls for the height of the table. A user interface including a rotary encoder allows fine adjustments to the height of the table to personalize and customize the user’s experience. Similarly, the user interface allows a user to customize the color of light emitted by the table to the user’s preference. In some embodiments, the control system 142 may include a wireless communication device that communicates with a wireless communication device on an external device. For example, interacting with the user interface 34 may control the operation of external components such as external lights, external display screens or the like. In further embodiments, the user interface may be used with a fixed table that does not include height adjustable legs.
