[0001] Cross - Reference to Related Applications

[0002] This patent application claims the benefit of priority of U.S. Provisional Patent Application No. 63 / 292,972, filed on Dec. 22, 2021, entitled "Adjustable And Stowable Workstation Assembly" (Attorney Docket No. 5983.469PRV), which is hereby incorporated herein by reference in its entirety. Technical Field

[0003] This document generally relates to, but is not limited to, workstations having a keyboard tray and a monitor mount coupled to a structure, and more particularly to an articulated arm assembly for adjusting the position of the workstation relative to the structure. Background Art

[0004] Workstations that house one or more electronic devices (e.g., one or more monitors, input devices, etc.) are commonly used in modern offices, hospitals, industrial facilities, or other locations. A workstation can include an articulated arm assembly, a work surface / keyboard tray assembly, and a monitor mount assembly. The workstation can be mounted on a structure (e.g., a wall, a desk, etc.). The arm assembly can provide height adjustment and / or articulation for the electronic devices coupled to the workstation. A user of the workstation can easily adjust the orientation of the electronic devices using the arm assembly to accommodate the user's changing posture throughout the day.

[0005] To reduce the space occupied by the workstation when not in use, the workstation can typically be stowed in an orientation where the arm assembly collapses near its mounting location on the structure, and the work surface / keyboard tray assembly folds toward the mounting location. When using the workstation, the monitor and input devices can be pulled away from the mounting location in an extended orientation. In the extended orientation, the workstation may be more accessible, and it can allow the user to interact with the user's environment (e.g., interact with a patient in a hospital ward, etc.). A workstation that can be easily maneuvered between a stowed orientation and an extended orientation will increase user satisfaction and will be adjusted more frequently to provide a more ergonomic positioning for the user.

[0031] Overview

[0032] The present disclosure describes a workstation having an articulated arm assembly for supporting one or more electronic devices, including but not limited to electronic displays, keyboards, laptops, and other computing devices, medical devices, scanners, etc. The workstation can be mounted on a structure including any fixed or mobile support surface (e.g., wall, desk, pole, cart, etc.). The articulated arm assembly can allow the workstation to translate between a series of positions between a stowed orientation and an extended orientation. Detailed Description

[0033] The following detailed description is exemplary in nature and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description provides some practical illustrations for implementing exemplary embodiments of the invention. Examples of construction, materials, dimensions, and manufacturing processes are provided for selected elements, and all other elements employ construction, materials, dimensions, and manufacturing processes known to those of ordinary skill in the art of the invention. Those skilled in the art will recognize that many of the examples mentioned have various suitable alternatives.

[0034] Figure 1-2 is an isometric view of a workstation 100 configured according to some examples of the present disclosure and including an arm assembly (e.g., Figure 1 arm assembly 110A) in a deployed orientation and a stowed orientation, respectively. One end of the arm assembly 110A may be coupled to a structure interface 112, and a mounting assembly 120A may be coupled to the other end of the arm assembly 110A. The arm assembly 110A may be configured to translate the mounting assembly 120A relative to the structure interface 112. In some example configurations, the arm assembly 110A may include a first arm 114 (e.g., a deployment arm) and a second arm 116 rotatably coupled to the first arm 114. The arm assembly 110A may translate the mounting assembly 120A relative to the structure interface 112. In some example configurations, the first arm 114 and the second arm 116 may be configured to cooperate to translate the mounting assembly horizontally between a deployed orientation and a stowed orientation. In some example configurations, the second arm 116 may be height adjustable. The second arm 116 may translate the mounting assembly vertically relative to the structure interface 112.

[0035] The structure interface 112 may be mounted on a fixed or movable structure (e.g., a wall, a desk, a cart, a pole, etc.). In some example configurations, the structure interface 112 may include an interface bracket. The interface bracket may be mounted directly on the structure. In other configurations, the structure interface 112 may include an interface assembly. The interface assembly may include one or more components for mounting the arm assembly 110A on the structure. For example, the interface assembly may include an interface bracket and a wall rail. The wall rail may be mounted on a wall, and the interface bracket may be coupled to the wall rail.

[0036] In some example configurations, the mounting assembly 120A may include a display interface 118 and a support tray (e.g., Figure 1-2of the support tray 122A). The display interface 118 and the support tray 122A can be rotatably coupled to the arm assembly 110A about a vertical axis 125. In some example configurations, rotation of the support tray 122A may cause the display interface 118 to rotate, while the display interface 118 is capable of rotating independently of the support tray 122A. The display interface 118 can further include a support post 124 and an angling assembly 126 coupled to the support post 124.

[0037] The angling assembly 126 can include a display interface bracket. The display interface bracket can be adapted to couple to an electronic display 105. The display interface 118 can be configured to hold the electronic display 105 above the support tray 122A, and the display interface 118 can be configured to change the orientation of the electronic display 105 relative to the support tray 122A (e.g., change the distance or angle of the electronic display 105 relative to the support tray 122A).

[0038] In some example configurations, the work surface 121 can be coupled to the support tray 122A. A user of the workstation 100 can place personal devices (e.g., paper, notebooks, calculators, one or more pens, etc.) on the work surface 121. In some example configurations, a keyboard can be placed on the work surface 121.

[0039] In other example configurations, a slide-out tray 128 (e.g., a keyboard tray) can be coupled to the support tray 122A, as Figure 2 shown. The slide-out tray 128 can be configured to hold an input device (e.g., a keyboard 106), and the input device can be placed on the slide-out tray 128. The slide-out tray 128 can translate between a retracted orientation and an extended orientation, in the retracted orientation, the keyboard 106 can be retracted beneath the work surface 121, and in the extended orientation, the slide-out tray 128 can be pulled out (e.g., to position the slide-out tray in front of the work surface 121) so that the keyboard 106 is accessible, as Figure 2 shown. In some example configurations, the slide-out tray 128 can be used as a drawer for storing personal items.

[0040] In some example configurations, a storage compartment 123 can be coupled to the support tray 122A, as Figure 1 shown. The storage compartment 123 can be a separate component and can be secured to the underside of the support tray 122A using one or more mechanical fasteners (screws, rivets, clamps, notches, latches, etc.). In other example configurations, the storage compartment 123 can be formed as part of the support tray 122A. The storage compartment 123 can be used to store one or more electronic components, including but not limited to a computer (e.g., a thick client, a thin client, or a zero client), a charging adapter, one or more cables, etc.

[0041] Figure 3 is a side view of workstation 100 configured according to an example of the present disclosure. Workstation 100 may include arm assembly 110B. Arm assembly 110B may include a single arm (e.g., height-adjustable arm 113), where the height-adjustable arm 113 may be similar to Figure 1 the second arm 116. Arm assembly 110B may have a first end 142 and a second end 144. The first end 142 of arm assembly 110B may be rotatably coupled to structure interface 112, and mounting assembly 120B may be rotatably coupled to the second end 144 of arm assembly 110B about vertical axis 125. Mounting assembly 120B may further include support tray 122B and display interface 118. In some example configurations, rotation of support tray 122A may cause display interface 118 to rotate, while display interface 118 is capable of rotating independently of support tray 122A.

[0042] Display interface 118 may be configured to hold electronic display 105 above support tray 122B. An input device (e.g., keyboard 106) may be located on support tray 122B. Arm assembly 110B may be used to change the orientation (e.g., vertical orientation, horizontal orientation, or both) of electronic display 105 and keyboard 106 relative to structure interface 112.

[0043] Figure 4A-4B is an exploded view of platform 210 and a partial view of arm assembly 110 configured according to some examples of the present disclosure. Platform 210 may be coupled to an end of arm assembly 110 (e.g., Figure 3 the second end 144 of arm assembly 110B). Platform 210 may be constructed in different configurations. In some example configurations, platform 210A may have a work surface 121 coupled to support tray 122A, as Figure 4A shown. A keyboard tray (e.g., Figure 2 the slide-out tray 128) may be coupled to support tray 122A below work surface 121. In other example configurations, platform 210B may be constructed without a work surface, as Figure 4B shown. The keyboard tray may be constructed as an integral part of support tray 122B. In any of these example configurations, interface component 320 may be coupled to the rear end of the platform near the center of platform 210. Interface component 320 may be configured to quickly couple platform 210 to arm assembly 110.

[0044] Figure 5 is platform 210 (e.g., Figure 4AIsometric view of the back end of the platform 210A). The interface component 320 may include an interface bracket 340 and a carrier block 350. The interface bracket 340 may be coupled to the first end 351 of the carrier block 350 (as Figure 8 shown), and the platform tilt hinge 325 may be located at the second end 352 of the carrier block 350 (as Figure 8 shown). The platform 210 may be rotatably coupled to the carrier block 350 at the platform tilt hinge 325. The interface bracket 340 may be adapted to releasably couple the carrier block 350 to the arm assembly 110.

[0045] Figure 6 Is a side perspective view of the platform 210 (e.g., Figure 4A the platform 210A) in a stowed orientation according to an example configuration of the present disclosure. The platform tilt hinge 325 may define a horizontal axis of rotation 356 (as Figure 8 shown). When the workstation is not in use, the platform 210 may rotate clockwise about the horizontal axis of rotation 356 toward the electronic display 105 to place the platform in a stowed orientation (as Figure 6 shown in). In the stowed orientation, the footprint of the workstation 100 can be reduced to save office space. When the workstation 100 is expected to be used by a user of the workstation, the platform 210 may rotate counterclockwise about the horizontal axis of rotation 356 away from the electronic display 105 to place the platform 210 in a use orientation.

[0046] Figure 7 Is a rear isometric view of the platform 210 (e.g., Figure 4A the platform 210A). The platform 210 may have a front end 211 and a rear end 212 opposite the front end 211. In some example configurations, a recess 215 may be formed on the rear end 212 near the center of the platform (e.g., the recess 215 may be formed on the support tray 122A). The interface component 320 may be at least partially located inside the recess 215. One or more apertures 217 may be formed in the recess. The platform 210 may be coupled to the interface component 320 through one or more apertures 217.

[0047] Figure 8-9 Is an isometric view showing the interface component (e.g., Figure 5 the interface component 320) in a folded orientation and an extended orientation, respectively, according to an example configuration of the present disclosure. The interface component 320 may include a carrier block 350, an interface bracket 340, and a hinge bracket 360. In some example configurations, a slider 370 may be coupled to the upper surface 349 of the carrier block 350.

[0048] The hinge bracket 360 may have a hinge portion 361 and a flat portion 362. The hinge portion 361 may be rounded. The flat portion 362 may extend from the hinge portion 361 in a lateral direction. One or more threaded holes 364 may be formed in the flat portion 362. When the platform 210 is coupled to the interface assembly 320, one or more of the threaded holes 364 may overlap with one or more of the apertures 217. One or more mechanical fasteners (e.g., screws, rivets, etc.) may be inserted through one or more of the apertures 217 located on the support tray 122 and may engage with one or more of the threaded holes 364 located on the hinge bracket 360 to securely couple the support tray 122 to the hinge bracket 360.

[0049] The hinge bracket 360 may be rotatably coupled to the carrier block 350 at the platform tilt hinge 325. The hinge bracket 360 may be adapted to rotate between a folded orientation and an extended orientation. In the folded orientation, the hinge bracket 360 may be folded against the carrier block 350, as Figure 8 shown. In the folded orientation, the hinge bracket 360 may be placed in a downward orientation (e.g., substantially vertical) and may rest against the second end 352 of the carrier block 350. The hinge bracket 360 may rotate (e.g., rotate 90 degrees, etc.) from the folded orientation to the extended orientation in a clockwise direction about a horizontal axis of rotation 356. In the extended orientation, the hinge bracket 360 may be placed in a flat orientation (e.g., substantially horizontal), as Figure 9 shown. Since the support tray 122 is coupled to the hinge bracket 360, as the hinge bracket 360 rotates from the folded orientation to the extended orientation, the support tray 122 and thus the platform 210 may rotate with the hinge bracket 360 from the use orientation to the stowed orientation. The folded orientation of the hinge bracket 360 may correspond to the use orientation of the platform 210, and the extended orientation of the hinge bracket 360 may correspond to the stowed orientation of the platform 210.

[0050] Figure 10 is Figure 8 an isometric view of the carrier block 350. The carrier block 350 may have a first end 351 and a second end 352. A rear wall 353 may be built into the carrier block 350 near the first end 351. The carrier block 350 may further include a first side wall 354 and a second side wall 355. The first side wall 354 and the second side wall 355 may extend from the rear wall 353 in a lateral direction, from the first end 351 of the carrier block 350 to the second end 352. An upper surface 349 may be coupled to the first side wall 354, the second side wall 355, and the rear wall 353 near the upper end 348 of the carrier block 350. The second end 352 of the carrier block 350 and the lower end 347 opposite the upper end 348 may be open between the first side wall 354 and the second side wall 355.

[0051] In an example configuration, the first spacer 357 and the second spacer 358 can be coupled to the rear wall 353, as Figure 10 shown. The first spacer 357 and the second spacer 358 can extend from the rear wall 353 in a lateral direction toward the second end 352. The carrier block 350 can further include a first aperture 371 and a second aperture 372. The first aperture 371 and the second aperture 372 can be elongated apertures formed in the upper surface 349.

[0052] In an example configuration, a first through hole 344 and a second through hole 345 can be formed in the first side wall 354 and the second side wall 355, respectively. The first through hole 344 and the second through hole 345 can be located near the upper end 348 and near the second end 352. The first through hole 344 and the second through hole 345 can be coaxial. An axis passing through the centers of the first through hole 344 and the second through hole 345 can form a first rotation axis 3561, as Figure 10 shown.

[0053] Figure 11 is Figure 8 an isometric view of the hinge bracket 360. The hinge bracket 360 can have a hinge portion 361 and a flat portion 362. A first side wall 365 and a second side wall 366 can be formed on the hinge bracket 360. The first side wall 365 and the second side wall 366 can extend from the flat portion 362 in a lateral direction. The first side wall 365 and the second side wall 366 can be near the hinge portion 361. A first through hole 367 and a second through hole 368 can be formed in the first side wall 365 and the second side wall 366, respectively. The first through hole 367 and the second through hole 345 can be coaxial. An axis passing through the centers of the first through hole 344 and the second through hole 345 can form a second rotation axis 3562 of the hinge bracket 360, as Figure 11 shown.

[0054] In an example configuration, the locking bracket 380 can be coupled to one of the first side wall 365 or the second side wall 366 of the hinge bracket 360 (e.g., coupled to the second side wall 366, as Figure 11 shown). In other example configurations, the locking bracket 380 can be formed as an integral part of the hinge bracket 360. The locking bracket 380 can include an inclined surface 382 and a recess 384.

[0055] Figure 12 is an isometric view of a spring assembly 390 according to an example configuration of the present disclosure. The spring assembly 390 can include one or more torsion springs (e.g., a first torsion spring 392 and a second torsion spring 395). The first torsion spring 392 and the second torsion spring 395 can be made of a known spring wire. The first torsion spring 392 and the second torsion spring 395 can be concentric.

[0056] In some example configurations, the spring wire can have a circular cross-section or a square cross-section. One or more coils of the spring wire can be wound in a circular orientation to form the body of a first torsion spring 392, as Figure 12 shown. The first torsion spring 392 can have a first leg 393 and a second leg 394. The first leg 393 and the second leg 394 of the first torsion spring can extend away from the body of the first torsion spring 392. Similarly, one or more coils of the spring wire can be wound in a circular orientation to form the body of a second torsion spring 395. The second torsion spring 395 can have a first leg 396 and a second leg 397. The first leg 396 and the second leg 397 of the second torsion spring 395 can extend away from the body of the second torsion spring 395. In some example configurations, the first leg 393 of the first torsion spring 392 and the first leg 396 of the second torsion spring 395 can be parallel to each other, and the second leg 394 of the first torsion spring 392 and the second leg 397 of the second torsion spring 395 can be parallel to each other.

[0057] The spring assembly 390 can further include a mandrel 398. The mandrel 398 can have a circular cross-section, and the mandrel 398 can have a through-hole 399 near the center. The mandrel 398 can be at least partially located inside the first torsion spring 392 and the second torsion spring 395. In some example configurations, a mechanical fastener 391 (e.g., a screw, a rivet, etc.) can be inserted through the through-hole 399 located at the center of the mandrel 398 to form a third rotation axis 3563 for the spring assembly 390, as Figure 12 shown.

[0058] Figure 13 is an isometric view of an interface assembly 320 according to an example configuration of the present disclosure. In the interface assembly 320, the hinge bracket 360 can be located between a first sidewall 354 and a second sidewall 355 of the carrier block 350, and the spring assembly 390 can be located between a first sidewall 365 and a second sidewall 366 of the hinge bracket 360. The first rotation axis 3561, the second rotation axis 3562, and the third rotation axis 3563 can coincide with each other to form a horizontal rotation axis 356 (as Figure 8As shown. In an example configuration, the first leg 393 of the first torsion spring 392 can rest against the first spacer 357, and the second leg 394 of the first torsion spring 392 can rest against the flat portion 362 of the hinge bracket 360. Similarly, the first leg 396 of the second torsion spring 395 can rest against the second spacer 358, and the second leg 397 of the second torsion spring 395 can rest against the flat portion 362 of the hinge bracket 360. The second leg 394 of the first torsion spring 392 and the second leg 397 of the second torsion spring 395 can apply a force to the flat portion 362 to bias the hinge bracket 360 toward the extended orientation (as Figure 9 shown). Since the platform 210 is coupled to the hinge bracket 360, the first torsion spring 392 and the second torsion spring 395 can bias the platform 210 to rotate in a clockwise direction toward the Figure 6 shown stowed orientation.

[0059] Figure 14 is an isometric view of an interface assembly 420 according to another example configuration of the present disclosure. The interface assembly 420 can include a carrier block 350 and a hinge bracket 460. The hinge bracket 460 can be rotatably coupled to the carrier block 350 about a horizontal axis of rotation 356, as previously described in connection with Figure 13 discussed.

[0060] The hinge bracket 460 can include a flat portion 462. In some example configurations, an adjustment assembly 400 can be coupled to the hinge bracket 460. The adjustment assembly 400 can include a retaining bracket 401 and an adjustment bracket 402. The retaining bracket 401 can be formed in a U-shaped configuration having a first side 403, a second side 404, and a base 405. The retaining bracket 401 can be coupled to the flat portion 462 of the hinge bracket 460. The base 405 of the retaining bracket 401 can be parallel to the flat portion 462 of the hinge bracket 460.

[0061] The adjustment bracket 402 can be located between the first side 403 and the second side 404 of the retaining bracket 401. The adjustment bracket 402 can translate relative to the retaining bracket 401 in a path perpendicular to the base 405. An adjustment screw 406 can be coupled to the base 405 of the retaining bracket 401 and to the flat portion 462 of the hinge bracket 460. The adjustment screw can be perpendicular to the base 405. The adjustment screw 406 can be rotatably coupled to the retaining bracket 401. The adjustment screw 406 can have a screw head 407. The screw head 407 can be located near the base 405. A nut 408 can be fixedly attached to the adjustment screw 406 near the hinge bracket 460, as Figure 14 shown. The screw head 407 and the nut 408 can prevent the adjustment screw 406 from translating perpendicular to the base 405.

[0062] Threaded holes can be formed in the adjustment bracket 402. The threaded holes can be concentric with the adjustment screw 406. The adjustment screw 406 can be at least partially located inside the threaded holes in the adjustment bracket 402, and the adjustment screw 406 can be threadedly engaged with the adjustment bracket 402. The adjustment bracket 402 can be adapted to translate along the longitudinal direction of the adjustment screw 406 when the adjustment screw 406 rotates.

[0063] In an example configuration, the second leg 394 of the first torsion spring 392 and the second leg 397 of the second torsion spring 395 can rest against the adjustment bracket 402, as Figure 14 shown. Translating the adjustment bracket 402 by rotating the adjustment screw 406 can change the angle between the first and second legs of the first torsion spring 392 and the second torsion spring 395 (e.g., change the angle between the first leg 393 and the second leg 394 of the first torsion spring 392). The angle between the first and second legs of the torsion spring can be related to the spring tension.

[0064] By manipulating the adjustment assembly 400 (e.g., rotating the adjustment screw 406), a user of the workstation 100 can selectively adjust the tension of the first torsion spring 392 and the second torsion spring 395 (e.g., rotating the adjustment screw 406 in a clockwise direction can increase the tension, while rotating the adjustment screw 406 in a counterclockwise direction can decrease the tension). Increasing the tension of the torsion spring can apply an increased torque to the hinge bracket 360 in the clockwise direction to counteract the weight of the platform 210 (e.g., increasing the tension of the torsion spring to counteract a heavier platform weight or decreasing the tension of the torsion spring to counteract a lighter platform weight).

[0065] Figure 15-16 is Figure 9 a cross-sectional view of the interface assembly 320 of. The front section of the interface assembly 320 is removed to make the internal components visible. The interface assembly 320 can include a carrier block 350 and a hinge bracket 360, as Figure 9 shown. The carrier block can have a rear wall 353, an upper surface 349, a first side wall 354, and a second side wall 355, as Figure 10 shown. A first aperture 371 and a second aperture 372 can be formed in the upper surface 349. The first aperture 371 and the second aperture 372 can extend in a first direction 410. The first direction 410 can be perpendicular to the second side wall 355 and point away from the second side wall 355, as Figure 15 shown.

[0066] In some example configurations, the interface component can include a lock component 375. The lock component 375 can further include a slider 370. The slider 370 can be located near the upper surface 349. A mechanical fastener 411 (e.g., a screw, a pin, etc.) can be inserted through the first aperture 371 and coupled to the slider 370. A locking pin 412 can be inserted through the second aperture 372 and coupled to the slider 370. The slider 370 can translate relative to the carrier block 350 parallel to the first direction 410. The mechanical fastener 411 and the locking pin 412 respectively inserted through the first aperture 371 and the second aperture 372 can guide the slider 370 through their translation relative to the carrier block 350.

[0067] In some example configurations, the locking pin 412 can be formed in an L shape, as Figure 15 shown. The locking pin 412 can have a first end 413 and a second end 414. The first end 413 of the locking pin 412 can be coupled to the slider 370, and the second end 414 of the locking pin 412 can extend parallel to the first direction 410 (e.g., extend perpendicular to the second sidewall 355). The second end 414 of the locking pin 412 can be formed in a certain profile (e.g., circular, conical, etc.).

[0068] The interface component 320 can further include an energy storage member 416 (e.g., a tension spring, a torsion spring, a compression spring, etc.). The energy storage member 416 can be coupled between the locking pin 412 and the carrier block 350. The energy storage member 416 can bias the slider 370 in a second direction opposite to the first direction 410.

[0069] In the interface component 320, the second sidewall 366 of the hinge bracket 360 can be adjacent to the second sidewall 355 of the carrier block 350. A locking bracket 380 having an inclined surface 382 and a recess 384 can be coupled to the second sidewall 366 of the hinge bracket 360, as Figure 11 shown. When the hinge bracket 360 rotates relative to the carrier block 350 about the horizontal rotation axis 356, the inclined surface 382 and the recess 384 can translate in an arcuate path in front of 414.

[0070] The hinge bracket 360, and thus the locking bracket 380, can be rotatably coupled to the carrier block 350. As the hinge bracket 360 rotates from an extended orientation (as Figure 9 shown) to a folded orientation (as Figure 8As shown, the inclined surface 382 can contact the second end 414 of the locking pin 412 at a first rotation angle (e.g., 80 degrees of rotation relative to the extended orientation, etc.). As the locking bracket 380 continues to rotate with the hinge bracket 360, the inclined surface 382 can push the locking pin 412 and the slider 370 along the first direction 410 by stretching the energy storage member 416. When the hinge bracket 360 is placed in the folded orientation at a second rotation angle (e.g., 90 degrees of rotation relative to the extended orientation, etc.), the recess 384 can coincide with the second end 414 of the locking pin 412. In the folded orientation, the energy storage member 416 can pull the locking pin 412 and the slider 370 in a second direction opposite to the first direction 410, such that the second end 414 of the locking pin 412 can be inserted into the recess 384 to lock the hinge bracket 360 in the folded orientation, as Figure 16 shown.

[0071] In some example configurations, the slider 370 can have a tab 374. A user of the workstation 100 can interact with the tab 374 to push the slider 370 and the locking pin 412 along the first direction 410 to unlock the hinge bracket 360 (e.g., the second end 414 can move away from the recess 384 to separate from the locking bracket 380, as Figure 15 shown). Once the locking bracket 380 is unlocked, the user of the workstation 100 can rotate the hinge bracket 360 from the folded orientation to the extended orientation to place the platform 210 in the stowed orientation, as Figure 6 shown. One or more energy storage members (e.g., the first torsion spring 392 and the second torsion spring 395, etc.) can provide lift assistance to reduce the amount of force that a user may apply to rotate the platform 210 from the extended orientation to the stowed orientation.

[0072] In some example configurations, when the locking pin 412 separates from the locking bracket 380, one or more energy storage members (e.g., the first torsion spring 392 and the second torsion spring 395) may have a tension sufficient to counteract the weight of the platform 210 and automatically rotate the platform 210 at least partially from the extended orientation toward the stowed orientation. One or more torsion springs can apply a force to the hinge bracket 360 to rotate it from the folded orientation toward the extended orientation. When the user of the workstation 100 unlocks the hinge bracket 360 (e.g., pushes the slider 370 along the first direction 410 to separate the locking pin 412 from the locking bracket 380 by moving the second end 414 of the locking pin 412 away from the recess 384), the force applied by one or more torsion springs to the hinge bracket 360 can cause the hinge bracket 360 to automatically rotate to a third rotation angle (e.g., 85 degrees of rotation relative to the extended orientation, etc.). This initial automatic rotation can indicate to the user that the hinge bracket 360 has been unlocked and the platform 210 is ready to rotate to the stowed orientation.

[0073] Figure 17 isFigure 1 Side view of the second arm 116. The second arm 116 may include a first block 450, a second block 451, an upper link arm 455, and a lower link arm 456. One end of the upper link arm 455 may be rotatably coupled to the first block 450, and the other end may be rotatably coupled to the second block 451. One end of the lower link arm 456 may be rotatably coupled to the first block 450, and the other end may be rotatably coupled to the second block 451. The upper link arm 455 and the lower link arm 456 may be parallel to each other to form a parallel link mechanism. The upper link arm 455 and the lower link arm 456 may rotate relative to the first block 450 to adjust the vertical distance between the first block 450 and the second block 451. The upper link arm 455 and the lower link arm 456 may remain parallel during adjustment to keep the second block 451 flush in any position.

[0074] In some example configurations, the first block 450 may be used to mount the second arm 116 to a structure (e.g., mounted to the first arm 114, mounted to the structure interface 112, etc.). One or more components (e.g., the platform 210, the display interface 118, etc.) may be coupled to the second block 451. The second arm 116 may be configured to translate one or more components relative to the first block 450 when the upper link arm 455 and the lower link arm 456 rotate relative to 450.

[0075] Figure 18 is Figure 17 Cross-sectional view of the second arm. In some example configurations, the second arm 116 may include an arm balance mechanism 465 for providing lift assistance during height adjustment. The arm balance mechanism 465 may provide a lifting force to counteract at least a portion of the combined weight (e.g., the combined weight of the platform 210, the electronic display 105, etc.) attached to the second arm 116.

[0076] The arm balance mechanism 465 may include a energy storage member 466 (e.g., a compression spring, etc.). The energy storage member 466 may be coupled to the lower link arm 456. The energy storage member 466 may have a first end and a second end. A cam follower 467 may be coupled to the first end of the energy storage member 466, and a tension adjustment assembly 470 may be coupled to the second end of the energy storage member 466. The cam follower 467 may contact a cam 453 formed on the first block 450 during the entire rotation of the lower link arm 456 relative to the first block 450.

[0077] Figure 19 is Figure 18An enlarged cross-sectional view of the tension adjustment assembly 470. The tension adjustment assembly 470 can be coupled to the lower link arm 456. The tension adjustment assembly 470 can include a first bevel gear 471 and a second bevel gear 472. The first bevel gear 471 can rotate about a first axis 473, and the second bevel gear can rotate about a second axis 474. The second axis 474 can be perpendicular to the first axis 473. The second bevel gear 472 can engage (e.g., interlock, connect, contact, etc.) with the first bevel gear 471 such that rotation of the first bevel gear 471 can cause rotation of the second bevel gear 472.

[0078] The tension adjustment assembly 470 can further include an adjustment screw 475 and an adjustment bracket 476. The adjustment screw 475 can be concentric with the second bevel gear 472. The adjustment screw 475 can be coupled to the second bevel gear 472 such that the adjustment screw 475 can be adapted to rotate in unison with the second bevel gear 472 about the second axis 474.

[0079] The adjustment bracket 476 can have a threaded hole 4761 near its center. The adjustment screw 475 can be at least partially located inside the threaded hole. The adjustment screw 475 can engage with the adjustment bracket 476 in a threaded manner. The adjustment bracket 476 can be configured to translate along the axial direction of the adjustment screw 475 (e.g., along the second axis 474) as the adjustment screw 475 rotates. The second end of the energy storage member 466 can be coupled to the adjustment bracket 476 (e.g., pressed against the adjustment bracket, etc.), as Figure 19 shown. The adjustment bracket 476 can be configured to change the tension (or compression amount) of the energy storage member 466 as the adjustment bracket translates along the second axis 474.

[0080] By rotating the lower link arm 456 relative to the first block 450, the height of the second block 451 relative to the first block 450 can be changed between a raised position and a lowered position. The energy storage member 466 can bias the second block 451 toward the raised position. During rotation of the second arm 116, the cam follower 467 can follow the cam profile of the cam 453 to further increase the tension (or compression amount) of the energy storage member 466. The cam profile of the cam 453 can be configured such that the lifting force provided by the arm balance mechanism 465 can be substantially constant throughout the rotation of the lower link arm 456 despite an increase in the tension (or compression amount) of the energy storage member 466.

[0081] Figure 20Is an exploded view of a tension adjustment assembly 470 configured according to an example of the present disclosure. A first bevel gear 471 may be formed on a first bevel gear shaft 480, and a second bevel gear 472 may be formed on a second bevel gear shaft 490. The first bevel gear shaft 480 may cooperate with the second bevel gear shaft 490 to drive an adjustment screw 475, which then translates an adjustment bracket 476 along a second axis 474 to increase the tension of a energy storage member 466.

[0082] The first bevel gear shaft 480 may have a first end 481 and a second end 482 opposite the first end 481. The first bevel gear 471 may be formed on the first bevel gear shaft 480 near the first end 481. In some configurations, the first bevel gear 471 may be formed as an integral part of the first bevel gear shaft 480. In other configurations, the first bevel gear 471 may be separately and fixedly attached to the first bevel gear shaft 480 during assembly.

[0083] The first bevel gear shaft 480 may be formed as four segments, including a first segment 483, a second segment 484, a third segment 485, and a fourth segment 486. The first segment 483 may extend from the first bevel gear 471 in one direction toward the first end 481. The first segment 483 may be formed with a circular cross-section and may have a first diameter. The second segment 484 may extend from the first bevel gear 471 in another direction toward the second end 482. The third segment 485 may extend from the second segment 484 toward the second end 482, and the fourth segment 486 may extend from the third segment 485 toward the second end 482. The second segment 484, the third segment 485, and the fourth segment 486 may be formed with circular cross-sections and may have a second diameter, a third diameter, and a fourth diameter, respectively. The third diameter of the third segment 485 may be less than the second diameter of the second segment 484 and the fourth diameter of the fourth segment 486. A first face 487 may be formed at the intersection between the second segment 484 and the third segment 485, and a second face 488 may be formed at the intersection between the third segment 485 and the fourth segment 486. The first face 487 and the second face 488 may extend from the third segment in a lateral direction. The third segment 485 may have a length 4851 between the first face 487 and the second face 488. A hexagonal recess 489 (as Figure 19 shown) may be formed at the second end 482 of the first bevel gear shaft 480.

[0084] The second bevel gear shaft 490 may have a first end 491 and a second end 492. The second bevel gear 472 may be formed on the second bevel gear shaft 490 near the first end 491. In some configurations, the second bevel gear 472 may be formed as an integral part of the second bevel gear shaft 490. In other configurations, the second bevel gear 472 may be separately and fixedly attached to the second bevel gear shaft 490 during assembly.

[0085] The second bevel gear shaft 490 can be formed into three sections, including a first section 493, a second section 494, and a third section 495. The first section 493 can extend from the second bevel gear 472 in one direction toward the first end 491. The first section 493 can be formed with a circular cross-section and can have a first diameter 4931. The second section 494 can extend from the second bevel gear 472 in another direction toward the second end 492. The third section 495 can extend from the second section 494 toward the second end 492. The second section 494 and the third section 495 can be formed with circular cross-sections and can have a second diameter and a third diameter, respectively. The third diameter of the third section 495 can be greater than the second diameter of the second section 494. A recess 496 (as Figure 19 shown) can be formed at the second end 492 of the second bevel gear shaft 490. The recess 496 can have any cross-section, including but not limited to a hexagon, a square, etc.

[0086] In some example configurations, the length 4851 of the third section 485 of the first bevel gear shaft 480 can be configured to receive the first diameter 4931 of the first section 493 of the second bevel gear shaft 490.

[0087] The adjustment screw 475 can have a first end 477 and a second end 478 opposite the first end 477. A boss 479 can be formed at the first end 477. The cross-section of the boss 479 can be formed into any shape, including but not limited to a hexagon, a square, etc. The cross-section of the boss 479 can match the cross-section of the recess 496 located on the second bevel gear shaft 490. In some configurations, the boss 479 can be inserted into the hexagonal recess 496 to couple the adjustment screw 475 to the second bevel gear shaft 490 such that the adjustment screw 475 can be configured to rotate with the second bevel gear shaft 490.

[0088] The adjustment screw 475 can extend from the boss 479 toward the second end to form a threaded shaft. The adjustment bracket 476 can be threadedly engaged with the adjustment screw 475 on the threaded shaft. The adjustment screw 475 can be flattened near the second end 478 to help prevent the adjustment bracket 476 from accidentally separating from the adjustment screw 475.

[0089] The first section 493 of the second bevel gear shaft 490 can be located near the third section 485 of the first bevel gear shaft 480. The length 4851 of the third section 485 can be configured (e.g., the length 4851 can be greater than the first diameter 4931 of the first section 493) such that the first section 493 can be received between the first face 487 and the second face 488. The first face 487 and the second face 488 can prevent the second bevel gear shaft 490 from translating in a direction parallel to the first axis 473.

[0090] Return reference Figure 20 , the hub 497 can be coupled to the adjustment screw 475 near the first end 477. The hub 497 can accommodate Figure 19 one or more thrust washers 498 as shown. In some configurations, the hub 497 can be formed as an integral part of the adjustment screw 475, or in other configurations, the hub 497 can be formed separately during assembly and coupled to the adjustment screw 475.

The bottom wall 503 can be coupled to the first side wall 501 and the second side wall 502. In some configurations, an inner wall 504 can be formed near the end of the lower link arm 456. The inner wall 504 can extend from the bottom wall 503 and can be coupled to the first side wall 501 and the second side wall 502. The inner wall 504 can extend in a lateral direction from the bottom wall 503 through at least a portion of the height of the first side wall 501 and the second side wall 502. A circular opening 505 can be formed near the center of the inner wall 504. The radius of the circular opening can match the radius of the second section 494 of the second bevel gear shaft 490.

[0092] The lower link arm 456 can further include one or more bosses 506 and apertures 507. The apertures 507 can be formed in the bottom wall 503 near the inner wall 504. The one or more bosses 506 and apertures 507 can be used to couple the tension adjustment assembly 470 to the lower link arm 456.

The distance between the first flange 513 and the second flange 514 can be configured to receive the second bevel gear 472. The third flange 515 can be adjacent to the second flange 514.

[0095] In some example configurations, the first flange 513, the second flange 514, and the third flange 515 can have a concave circular profile at their respective upper ends. The radius of the concave profile on the first flange 513 can match the radius of the first section 493 of the second bevel gear shaft 490. The radius of the concave profile on the second flange 514 can match the radius of the second section 494 of the second bevel gear shaft 490. The radius of the concave profile on the third flange 515 can match the radius of the third section 495 of the second bevel gear shaft 490.

The gear assembly 520 can include a housing 510, a first bevel gear shaft 480 having a first bevel gear 471, and a second bevel gear shaft 490 having a second bevel gear 472. The third section 485 and the fourth section 486 of the first bevel gear shaft 480 can be inserted into the central opening 511 of the housing 510. The second section 484 can extend outside the housing 510. In some configurations, the first face 487 can be located above the upper end 516 of the housing 510.

[0097] The second bevel gear shaft 490 can be inserted into the housing 510 such that the second bevel gear 472 can be located between the first flange 513 and the second flange 514.
