A WORKSTATION WITH MODULAR CONSTRUCTION

TECHNICAL FIELD

This document pertains generally, but not by way of limitation, to modular construction of workstations with height adjustable worksurface.

BACKGROUND

Computing workstations are widely used in different parts of a facility (e.g., production floor, assembly line, warehouse, hospital patient room, or the like). These workstations can be stationary (e.g., mounted on a wall, mounted on a pole, mounted on a table, or the like), or they can be mobile having a wheeled base. Some workstations can be powered using a built-in power system, others can be non-powered. Some workstations can have a CPU holder and at least one display mounting option, yet other workstations can be used with a notebook that does not require an additional display mount. Some workstations can require additional accessories (e.g., a printer, a locking drawer, one or more shelves, a tool holder, a scanner holder, or the like) depending on their use. Therefore, an easily configurable mobile workstation based on a common platform would be very desirable. The user of the workstation can build the workstation with desired capabilities using some standard building blocks.

DETAILED DESCRIPTION

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 present invention. Examples of constructions, materials, dimensions, and manufacturing processes are provided for selected elements, and all other elements employ that which is known to those of ordinary skill in the field of the invention. Those skilled in the art will recognize that many of the noted examples have a variety of suitable alternatives.

FIGS. 1 and 2 are a front and a rear perspective views of an example of a workstation 100, respectively. In some example configurations, the workstation 100 can include a wheeled base 30. A support column 20 can be coupled to the wheeled base 30 at a first end and a head unit assembly 10 can be coupled to the support column 20 proximate a second end. In some example configurations, the head unit assembly 10 can be slidingly engaged with the support column 20.

The support column 20 can have any shape. In some example configurations, the support column 20 can have a rectangular prism construction. The support column 20 can have front surface 25 and a rear surface 26 each having a width 21. The front surface 25 and the rear surface 26 can be coupled to each other via right and left sidewalls 23 with a depth 22. The width 21 and the depth 22 can be in a horizontal plane. The width 21 can be larger than the depth 22. The support column 20 can be elongated in a direction perpendicular to the horizontal plane formed by the width 21 and the depth 22. The elongated length of the support column 20 can form a height of the support column 20. The height of the support column 20 can be substantially larger than the width 21 and the depth 22. The front face 25, the rear face 26 and the sidewalls 23 can form an enclosed volume inside the support column 20. A height adjustment mechanism (e.g., the lift mechanism 372 of FIG. 29, or the linear actuator 380 of FIG. 30) can be located in the enclosed volume. In some example configurations, the head unit assembly 10 can be coupled to the lift mechanism. The lift mechanism can provide assistance for the user of the workstation 100 to adjust a distance between the base and the head unit assembly 10.

In some example configurations, the head unit assembly 10 can include a worksurface 13 and a keyboard tray 15. The keyboard tray 15 can be slidably engaged with the head unit assembly 10. The keyboard tray 15 can be stowed under the worksurface 13 when it is not in use, and it can slide forward away from the worksurface 13 to expose a keyboard (not shown) located on the keyboard tray 15.

In some example configurations, the workstation 100 can include a rack assembly 50 and a display mounting assembly 60. The rack assembly 50 can be coupled to the head unit assembly 10 proximate to its rear end, and the display mounting assembly 60 can be coupled to the rack assembly 50. In other configurations, the display mounting assembly 60 can be directly coupled to the head unit assembly 10 without a rack assembly.

In some example configurations, the display mounting assembly 60 can include a display mounting riser 62, and a tilt assembly 70. The tilt assembly 70 can be operationally coupled to the display mounting riser 62. One or more displays (e.g., the display 442 of FIG. 37) can be coupled to the display mounting riser 62 to position the one or more displays over the worksurface 13.

In some example configurations, an arm assembly 80 can be optionally coupled between the tilt assembly 70 and the display mounting riser 62. In other configurations, the tilt assembly 70 can be directly coupled to the display mounting riser 62. The arm assembly 80 can articulate in a horizontal plane to change an orientation (e.g., change a position or angle) of the tilt assembly 70 relative to the display mounting riser 62. In some example configurations, the tilt assembly 70 and the arm assembly 80 can translate in a vertical direction relative to the display mounting riser 62 to adjust a distance between the tilt assembly 70 and the worksurface 13. In an example, the arm assembly 80 can be similar to (and can incorporate components of) the arm assembly described in commonly assigned U.S. Patent U.S. Pat. No. 10,646,033 to Lindblad et al., entitled “HEIGHT ADJUSTABLE PLATFORMS AND ASSOCIATED MECHANISMS”, which is hereby incorporated by reference herein in its entirety.

The workstation 100 can further include a power system 90. The power system 90 can be located inside a power system housing 91. The power system housing 91 can be coupled to the wheeled base 30. One or more electrical components (e.g., a computer, a display, a printer, a scanner, or the like) can be coupled to the workstation 100. The power system 90 can be electrically connected to the one or more electrical components coupled to the workstation 100.

In some example configurations, a front T-slot 27 and a rear T-slot 28 can be formed on the front face 25 and the rear face 26 of the support column 20, respectively. The front T-slot 27 and the rear T-slot 28 can be useful to couple one or more accessories (e.g., a shelf, a drawer, or the like) to the support column 20 as illustrated in FIG. 34. In other configurations, the rear T-slot 28 can be used to couple the support column 20 to a structure (e.g., a wall) as illustrated in FIG. 11.

FIG. 3 is an exploded view of the workstation 100 of FIG. 1 according to an example configuration of the current disclosure. The workstation 100 can include one or more modules including, but not limited to, a wheeled base 30, a support column 20, a head unit assembly 10, a rack assembly 50, a display mounting riser 62, a tilt assembly 70, and a power system housing 91. The one or more modules can be coupled together to form the workstation 100.

FIG. 4 is a perspective view of the tilt assembly 70 of FIG. 3. The tilt assembly 70 can include a tilt mechanism 72, a connector bracket 73, and a display attachment bracket 74. The tilt mechanism 72 can be coupled to the connector bracket 73. The display attachment bracket 74 can be coupled to a display on one side and coupled to the tilt mechanism 72 on the other side. In some configurations, the display attachment bracket 74 can be removably coupled to the tilt mechanism 72.

The tilt assembly 70 can be operationally coupled to the display mounting riser 62 (e.g., the connector bracket 73 can be coupled to the arm assembly 80 of FIG. 1). The tilt mechanism 72 can be adapted to change an orientation (e.g., change an angle) of the display relative to the display mounting riser 62. The tilt assembly 70 can hold a single display over the workstation 100. In other example configurations, it can be desirable to attach two or more displays to the workstation 100 using two or more tilt assemblies as illustrated in FIG. 31.

FIG. 5 is a bow assembly 75 according to an example configuration of the current disclosure. The bow assembly 75 can include a bow 76, two or more tilt assemblies (e.g., a first tilt assembly 70A and a second tilt assembly 70B), and a handle assembly 77. In some configurations, the bow assembly 75 can be operationally coupled to the display mounting riser 62 (e.g., the bow 76 can be coupled to the arm assembly 80 of FIG. 1). In other configurations, the bow assembly 75 can be directly coupled to the display mounting riser 62. The bow assembly 75 can be useful to hold the two or more displays over the worksurface 13. Two or more displays can be coupled to the bow assembly 75 through the two or more tilt assemblies (70A and 70B). In an example configuration, the tilt assembly 70 and bow assembly 75 can be similar to (and can incorporate components of) the tilt and bow assemblies described in commonly assigned U.S. Patent U.S. Pat. No. 11,112,057 to Janechek et al., entitled “DISPLAY MOUNTING SYSTEM AND METHOD”, which is hereby incorporated by reference herein in its entirety.

FIG. 6 is a perspective view of a non-powered workstation 110 according to an example configuration of the current disclosure. The non-powered workstation 110 can include a wheeled base 30, a support column 20, and a head unit assembly 10. In this example configuration, the non-powered workstation 110 does not have a resident power system. An external power source can be used to provide electrical power to the one or more electronic components (e.g., laptop computer, printer, scanner, or the like) coupled to the non-powered workstation 110. An outlet strip with multiple power outlets (not shown) can be coupled to the non-powered workstation 110. The outlet strip can be connected to the external power source, and the one or more electronic components can be electrically connected to the outlet strip to receive electrical power.

FIG. 7 is an exploded view of a sub-assembly between the

wheeled base 30 and the support column 20 of FIG. 3. The wheeled base 30 can include a first base member 301 and a second base member 302. The second base member 302 can be parallel to and spaced apart from the first base member 301. The wheeled base 30 can further include a third base member 303. The third base member 303 can be elongated in a transverse direction to the first base member 301 and the second base member 302. The third base member 303 can be coupled to the first base member 301 in one end and coupled to the second base member 302 in the other end. The first base member 301, the second base member 302, and the third base member 303 can be made of a structural material such as aluminum casting, extrusion, sheet metal stamping, or the like.

A housing member 305 can be coupled to the third base member 303 as illustrated in FIG. 8 according to an example configuration of the current disclosure. The housing member 305 can include a first wall 311 and a second wall 312 opposite to the first wall 311. The first wall 311 and second wall 312 can be coupled to each other through a first side wall 313 and a second side wall 314 opposite to the first side wall 313. The housing member 305 can have a hollow section 317. An upper end 315 of the housing member 305 can be open between the first wall 311, the second wall 312, the first side wall 313 and the second side wall 314 to form the hollow section 317 inside the housing member 305. A lower end of the hollow section 317 can be closed by a base 316.

In some example configurations, the housing member 305 can have one or more guides 320 formed on the first wall 311 and the second wall 312. The one or more guides 320 can protrude out of the first wall 311 and second wall 312 into the hollow section 317, and they can be elongated from the base 316 towards the upper end 315 of the housing member 305. The one or more guides 320 can have varying height from the wall they are attached to (e.g., they can be higher proximate to the base 316 compared to their height proximate to the upper end 315 as illustrated in FIG. 8). The one or more guides 320 can be useful to locate the support column 20 relative to the housing member 305 during assembly (as illustrated in FIG. 7). One or more threaded holes 322 and one or more apertures 324 can be formed on the base 316. In some example configurations, the housing member 305 can be made of a structural material such as aluminum casting, extrusion, sheet metal stamping, or the like.

The housing member 305 can be coupled to the wheeled base 30 using one or more mechanical fasteners (e.g., screws, or the like, not shown). The one or more mechanical fasteners can be inserted through one or more apertures (not shown) located on the third base member 303 and threadingly engage with the housing member 305 (e.g., threadingly engage with the one or more threaded holes 322 located on the base 316). In other configurations, the housing member 305 can be formed as an integral part of the third base member 303.

In some example configurations, a block 210 can be coupled to the lower end of the support column 20 as illustrated in FIG. 9. The block 210 can have a first side 211 and a second side 212 opposite the first side 211. The first side 211 and the second side 212 of the block 210 can be joined by lateral sides. An outside profile of the block 210 can match an inside profile of the hollow section 317 of the housing member 305. The block 210 can be made of a structural material such as aluminum casting, sheet metal stamping, or the like.

In some example configurations, one or more channels 214 can be formed on the first side 211 and the second side 212 of the block 210. The one or more channels 214 can have varying depth (e.g., the one or more channels 214 can be deeper proximate to the lower end 216 of the block 210 as compared to the depth of the one or more channels 214 proximate an upper end 217 of the block 210 away from the lower end 216. The block 210 can further include one or more threaded holes 219 formed on the lower end 216.

The hollow section 317 of the housing member 305 can be configured to receive the block 210 during the sub-assembly of the support column 20 with the wheeled base 30 as illustrated in FIG. 7. The one or more guides 320 located on the housing member 305 can coincide with the one or more channels 214 formed on the block 210. The one or more channels 214 can be configured to receive the one or more guides 320.

The block 210 can be at least partially inserted into the housing member 305. One or more mechanical fasteners (e.g., screws, or the like, not shown) can be coupled to the housing member 305 (e.g., inserted through the one or more apertures 324 shown in FIG. 8) and threadingly engage with the one or more threaded holes 219 to securely fasten the support column 20 to the housing member 305. In other configurations, an autolocking feature (e.g., a detent, a hook, or the like, not shown) can be built into the housing member 305. The auto locking feature can secure the block 210 into the housing member 305 as the block 210 is inserted into the housing member 305. In yet other configurations, the autolocking feature can temporarily hold the block 210 and the housing member 305 together, and a mechanical fastener (not shown) in cooperation with the autolocking feature, can securely fasten the block 210 to the housing member 305.

In some example configurations, the wheeled base 30 can include one or more sliding or rolling members (e.g., casters, wheels, gliders, or the like). The sliding or rolling members (e.g., one or more wheels 304 of FIG. 6) can provide assistance to transfer a workstation (e.g., the non-powered workstation 110) within a facility. In some configurations, the one or more wheels 304 can include a wheel lock 306. The wheel lock 306 can be selectively activated by the user of the non-powered workstation 110 to prevent any unintentional movement of the wheeled base 30.

In some configurations, the support column 20 can include a movable bracket 220 as illustrated in FIG. 12. The movable bracket 220 can be located proximate an upper end of the support column 20. The movable bracket 220 can be slidingly engaged with the support column 20 to travel along at least a portion of the support column 20 in longitudinal direction. One or more arms (e.g., a first arm 221 and a second arm 222 of FIG. 7) can be coupled to the movable bracket 220. In some configurations, the one or more arms can be formed as integral parts of the movable bracket 220.

In some configurations of the workstation (e.g., the non-powered workstation 110), a first opening 201 and a second opening 202 can be formed on the front face 25 of the support column 20. The first opening 201 and the second opening 202 can be elongated in longitudinal direction along at least a portion of the support column 20. The first arm 221 and the second arm 222 can be inserted through the first opening 201 and the second opening 202, respectively, and they extend away from the front face 25 of the support column 20 in a transverse direction. The one or more arms (e.g., a first arm 221 and a second arm 222) can be used to couple the head unit assembly 10 to the movable bracket 220. The movable bracket 220 can be configured to translate along at least a portion of the support column 20 to provide height adjustment for the head unit assembly 10.

FIG. 10 illustrates exploded view of another example configuration of a workstation (e.g., a wall mounted workstation 120). The wall mounted workstation 120 can be coupled to a wall 1000. The wall mounted workstation 120 can have a housing member 325. The housing member 325 can have similar features of the housing member 305 of FIG. 8 (e.g., the one or more guides 320, the hollow section 317, the base 316, or the like). In some configurations, the housing member 325 can have one or more flanges 326. One or more apertures 327 can be formed on the one or more flanges 326. The housing member 325 can be coupled to the wall 1000. A mechanical fastener (e.g., a wall anchor, a screw, or the like, not shown) can be inserted through the one or more apertures 327 located on the one or more flanges 326 and engage with the wall 1000 to securely fasten the housing member 305 to the wall 1000.

The support column 20 can be coupled to the housing member 325 (e.g., the block 210 can be inserted into the housing member 325 as discussed in previous sections in relation to FIGS. 8-9) to position the support column 20 proximate to the wall 1000. The one or more modules described in this disclosure (e.g., the head unit assembly 10, the rack assembly 50, the display mounting assembly 60, and others) can be coupled to the support column 20 to form the wall mounted workstation 120. In some example configurations, a security bracket 329 can be coupled to the wall 1000 and engage with the support column 20 proximate to its upper end as illustrated in FIG. 10. The security bracket 329 can prevent any undesirable motion (e.g., vibration, tilting, or the like) of the wall mounted workstation 120 during use.

FIG. 11 illustrates yet another example configuration of a workstation 125. The workstation 125 can include a holding bracket 330. The holding bracket 330 can be used to couple the workstation 125 to a structure (e.g., a wall 1000). The holding bracket 330 can have a first face 331 and a second face 332 opposite the first face 331. The second face 332 can be located proximate the wall 1000, and in some configurations, the second face 332 can rest against the wall 1000. The holding bracket 330 can be secured to the wall 1000 using mechanical fasteners including, but not limited to, screws, anchors, or the like. The one or more T-slot inserts 335 can be coupled to the first face 331 of the holding bracket 330. The one or more T-slot inserts 335 can have a matching profile with the rear T-slot 28 located on the rear face 26 of the support column 20. The rear T-slot 28 can be configured to receive the one or more T-slot inserts 335.

The holding bracket can further include a stop surface 333. The stop surface 333 can be located proximate the lower end of the holding bracket 330. The stop surface 333 can extend out of the first face 331 of the holding bracket 330 in a transverse direction.

After the holding bracket 330 is coupled to the wall 1000, the support column 20 can be coupled to the holding bracket 330. The one or more T-slot inserts 335 can be inserted into the rear T-slot 28 starting from the lower end of the rear T-slot 28. The support column 20 can slide relative to the holding bracket towards the stop surface 333 until the support column 20 rests against the stop surface 333. The one or more modules of this disclosure (e.g., the head unit assembly 10, the rack assembly 50, the display mounting assembly 60, and others) can be coupled to the support column 20 to form the workstation 125.

FIG. 12 is a partial cross-sectional view of the support column 20. The upper end of the support column 20 is cut off to make the movable bracket 220 visible. In some example configurations, the movable bracket 220 can be formed in a U-shaped cross-section as illustrated in FIG. 13. The movable bracket 220 can have a base 223, a first arm 221 and a second arm 222. The first arm 221 and the second arm 222 can extend from the base 223 in a transverse direction. In some configurations, the first arm 221 and the second arm 222 can each have an upper portion 224 and a lower portion 225 (as illustrated in FIG. 13). In other configurations, the upper portion 224 and the lower portion 225 can be joined in one arm portion. In some configurations, the base 223 of the movable bracket 220 can be contained inside the support column 20. The base 223 can be coupled to a lift mechanism 372 located inside the support column 20 as illustrated in FIG. 29.

In some configurations, the first arm 221 and the second arm 222 can include one or more through holes 226. The one or more through holes 226 can be useful to attach one or more couplers (e.g., a first coupler 227A and a second coupler 227B) to the movable bracket 220 as illustrated in FIG. 12. In some example configurations, the first coupler 227A and the second coupled 227B can be identical.

FIGS. 14A-14B are a side view and a perspective view of a coupler 227 according to an example configuration of the current disclosure. The coupler 227 can include a base portion 230 and a raised portion 231. The base portion 230 can have a first surface 232 and a second surface 233 opposite the first surface 232. The base portion 230 can have a width and a height. The height can be larger than the width. The base portion 230 can be elongated from a first end 234 to a second end 235 in height direction.

The raised portion 231 can extend away from the first surface 232 in a transverse direction, and one or more tabs 236 can be formed on the second surface 233. The one or more tabs 236 can be used to key (e.g., locate, register, orient, or the like) the coupler 227 to the first arm 221 and the second arm 222.

The raised portion 231 can be elongated between a lower end and an upper end where the lower end can be proximate to the first end 234 of the base portion 230 and the upper end can be proximate to the second end 235 of the base portion 230. The width of the raised portion 231 can vary between the lower end and the upper end (e.g., the width of the raised portion 231 at the lower end can be larger than the width of the raised portion 231 at the upper end as illustrated in FIG. 14B).

The raised portion 231 can be coupled to the first surface 232 on one end and a ridge 237 can be formed on the other end as illustrated in FIG. 14A. In some example configurations, a flange 238 can be formed on the raised portion 231 proximate to the lower end. The flange 238 can extend away from the raised portion 231. An aperture 239 can be formed on the flange 238, and one or more threaded holes 240 can be formed on the base portion 230.

FIG. 15 is a close-up perspective view of a coupler 227 (e.g., the first coupler 227A of FIG. 12) as attached to an arm (e.g., the first arm 221) of the movable bracket 220. The second surface 233 of the first coupler 227A can be in contact with the first arm 221. The one or more tabs 236 can locate (e.g., key, register, orient, or the like) the first coupler 227A relative to the first arm 221. One or more mechanical fasteners (e.g., screws, or the like, not shown) can be used to securely attach the first coupler 227A to the first arm 221. For example, the one or more mechanical fasteners (not shown) can be inserted through the one or more through holes 226 (shown in FIG. 13) located on the first arm 221, and threadingly engage with the one or more threaded holes 240 (shown in FIG. 14B) located on the first coupler 227A.

A first receiver 250A and a second receiver 250B can be coupled to the head unit assembly 10 proximate to the read end 12. The first receiver 250A and the second receiver 250B can be configured to receive the first coupler 227A and the second coupler 227B (shown in FIG. 12), respectively, to removably couple the head unit assembly 10 to the support column 20.

In some example configurations, one or more accessories 18 can be coupled to the head unit assembly 10. The one or more accessories 18 can include, but not limited to, cup holder, scanner holder, printer holder, or the like.

FIG. 17 is a close-up perspective view of a receiver (e.g., the second receiver 250B of FIG. 16). The second receiver 250B can have a receiver body 251 having a first surface 252, a second surface 253 opposite the first surface 252, and a third surface 254. The third surface 254 can be located on an end of the receiver body 251 and it can be oriented in a transverse direction to the first surface 252 and the second surface 253. The second receiver 250B can be an elongated component between a lower end 256 and an upper end 257.

A pocket 255 can be formed over the third surface 254. The pocket 255 can extend from the lower end 256 towards the upper end 257. In some example configurations, the pocket 255 can have a rectangular cross-section. In other configurations, the pocket 255 can have other cross-sections (e.g., elliptical, round, or the like). A threaded hole 258 can be formed on the lower end 256 of the second receiver 250B.

The pocket 255 can have a height, a width, and a depth. The height of the pocket 255 can extend from the lower end 256 towards the upper end 257 and the width can be in a transverse direction to the height. The depth of the pocket 255 can be perpendicular to the third surface 254. The depth of the pocket 255 can be configured to receive the ridge 237 of the coupler 227.

The receiver (e.g., the second receiver 250B) can further include a receiver opening 259 at an outer surface of the pocket 255. A lip 260 can be formed on at least a portion of an outer end of the receiver opening 259. The receiver opening 259 can be configured to receive the raised portion 231 of the coupler 227. The ridge 237 can be inserted into the pocket 255. The ridge 237 can be trapped behind the lip 260 when the coupler 227 is inserted into the receiver opening 259.

In some example configurations, the width of the pocket 255 and the receiver opening 259 can decrease in size as the pocket 255 extends from the lower end 256 towards the upper end 257.

In the assembled configuration of the head unit assembly 10 with the support column 20 (e.g., the first coupler 227A and the second coupler 227B can be inserted in to the first receiver 250A and the second receiver 250B, respectively), the aperture 239 located on the first coupler 227A and the second coupler 227B can be concentric with the threaded hole 258 located on the first receiver 250A and the second receiver 250B, respectively. A mechanical fastener (e.g., a screw, or the like, not shown) can be inserted through the apertures 239 and engage with the threaded holes 258 to secure the receiver on to the coupler (e.g., to secure the first receiver 250A on to the first coupler 227A, and to secure the second receiver 250B on to the second coupler 227B).

FIG. 18 is a front perspective view of the sub-assembly between the head unit assembly 10 and the support column 20. The head unit assembly 10 can include a first hook 261A, a second hook 261B, and a head unit chassis 265. The head unit chassis 265 can be coupled to the first hook 261A and the second hook 261B. The first hook 261A and the second hook 261B can be rotatingly coupled to the first receiver 250A and the second receiver 250B. One or both of the first hook 261A and the second hook 261B can be manipulated (e.g., rotated, pushed, pulled, or the like) relative to the first receiver 250A or the second receiver 250B, respectively, to level the head unit chassis 265 after it is coupled to the support column 20.

Construction of the first hook 261A can be similar to the construction of the second hook 261B. Similarly, construction of the first receiver 250A can be similar to the second receiver 250B. For simplicity, the first hook 261A and the second hook 261B will be called the hook 261, and the first receiver 250A and the second receiver 250B will be called the receiver 250 in the following sections to explain their construction and interaction.

FIG. 19 is a perspective view of a hook 261 (e.g., the first hook 261A or the second hook 261B of FIG. 18) according to an example configuration of the current disclosure. The hook 261 can have a hook body 270. The hook body 270 can be elongated between a first end 271 and a second end 272. A first flange 273 and a second flange 274 can be coupled to the hook body 270 proximate to the second end 272. In some example configurations, the hook 261 can further include a third flange 275. The third flange 275 can be coupled to the hook body 270 proximate to the second end 272. The third flange 275 can be elongated in a transverse direction from the hook body 270.

A first threaded hole 276 and a second threaded hole 277 can be formed on the first flange 273 and the second flange 274, respectively. The hook 261 can further include a third threaded hole 278 and a fourth threaded hole 279 located proximate to the first end 271 of the hook 261. A first aperture 280 and a second aperture 281 formed on the hook body 270. The first aperture 280 and the second aperture 281 can be elongated holes formed on the hook body 270 proximate to the first end 271 and the second end 272, respectively.

The hook 261 can further include a groove 282 and an overhang 283. The groove 282 can be formed in a circular profile having a groove radius 284. The groove 282 can connect the overhang 283 with the hook body 270 to form a channel 285 proximate to the first end 271 of the hook 261. The channel 285 can be configured to receive at least a portion of the receiver 250.

FIG. 20 is a perspective view of a receiver 250 (e.g., the first receiver 250A or the second receiver 250B of FIG. 18). The receiver 250 can have a receiver body 251 having a lower end 256 and an upper end 257. A bead 290 can be formed on the receiver body 251 proximate to the upper end 257. The bead 290 can be formed in a circular profile having a bead radius 291. The bead radius 291 can be smaller than the groove radius 284. The bead 290 can be configured to fit inside the groove 282. One or more threaded holes (e.g., a fifth threaded hole 292, and a sixth threaded hole 293) can be formed on the receiver body 251.

FIGS. 21 and 22 are a close-up perspective view and a cross-sectional view, respectively, of the coupling between a hook 261 and a receiver 250 according to an example configuration of the current disclosure. The channel 285 formed between the hook body 270 and the overhang 283 can be configured to receive at least a portion of the receiver body 251. At least a portion of the receiver body 251 can be inserted into the channel 285 until a contact is established between the groove 282 and the bead 290. The hook 261 can be configured to rotate relative to the receiver 250 over an interface surface 294 between the groove 282 and the bead 290.

FIG. 23 is a cross-sectional view of the coupling between the hook 261 and the receiver 250. In some example configurations, a first set screw 295 and a second set screw 296 can threadingly engage with the first threaded hole 276 and the second threaded hole 277, respectively. The cross-section shown in FIG. 23 is the vertical cross-section passing through a centerline of the second set screw 296.

The first set screw 295 and the second set screw 296 can extend out of the rear face 286 of the first flange 273 and the rear face 287 of the second flange 274, respectively. The user of the workstation can rotate the first set screw 295 and the second set screw 296 to adjust the lengths of the extended sections of the first and the second set screws behind the rear faces of the first flange 273 and the second flange 274.

The tip (not shown) of the first set screw 295 and the tip 297 of the second set screw 296 can contact the first surface 252 of the receiver body 251. As the lengths of the extended sections of the first set screw 295 and the second set screw 296 increase, they can push the hook body 270 away from the receiver body 251, and thus, rotate the hook 261 around the bead 290 of the receiver 250 and change an angle of the hook 261 relative to the receiver 250. Therefore, one or both of the first set screw 295 and the second set screw 296 located on the first hook 261A and the second hook 261B can be rotated to change an angle of one or both of the first hook 261A and the second hook 261B to level (e.g., make horizontal, or the like) the head unit chassis 265.

FIG. 24 is a cross-sectional view of the coupling between the hook 261 and the receiver 250. In some example configurations, the workstation assembly can include a first screw 298 and a second screw 299. The first screw 298 can be inserted through the first aperture 280 and it can be threadingly engaged with the fifth threaded hole 292. The second screw 299 can be inserted through the second aperture 281 and it can be threadingly engaged with the sixth threaded hole 293. The cross-section shown in FIG. 24 is the vertical cross-section passing through a centerline of the first screw 298 and the second screw 299. The first aperture 280 and the second aperture 281 are elongated holes in vertical direction. The first aperture 280 and the second aperture 281 allow the angle of the hook body 270 change relative to the receiver body 251 by turning the set screws relative to the hook body 270 as discussed above. During the angle adjustment, the first screw 298 and the second screw 299 can be loosely connected to the receiver body 251. After the angle of the hook body 270 is changed to level the head unit chassis 265, the first screw 298 and the second screw 299 can be tightened to securely couple the hook 261 to the receiver 250.

FIG. 25 is a perspective view of the head unit assembly 10 according to an example configuration of the current disclosure.

The first seat 361 and the second seat 362 can be fixedly attached to the first base member 301 and the second base member 302, respectively, via various methods including, but not limited to, welding, fastening using screws, or the like. In other configurations, the first seat 361 and the second seat 362 can be formed as an integral part of the first base member 301 and the second base member 302, respectively. The first seat 361 and the second seat 362 can be useful to couple the power system housing 91 to the wheeled base 30.

The power system housing 91 can have a first side 363 and a second side 364 opposite the first side 363. A first limb 365 can be coupled to the first side 363, and a second limb 366 can be coupled to the second side 364. In the assembled configuration as illustrated in FIG. 1, the first limb 365 can overlap with the first seat 361, and the second limb 366 can overlap with the second seat 362. In some example configurations, the first limb 365 and the second limb 366 can be fixedly attached to the first seat 361 and the second seat 362, respectively, by means of one or more known mechanical fasteners (e.g., one or more screws, one or more detents, or the like, not shown). In other configurations, the power system housing 90 can be coupled to the wheeled base 30 using one or more lock mechanisms (e.g., one or more cam locks, one or more levers, or the like, as illustrated in FIGS. 42A-42B).

FIG. 29 illustrates a front view of the support column 20 of FIG. 1 according to an example configuration of the current disclosure. Portions of the support column 20 (e.g., a front face 25) have been hidden for clarity. The support column 20 can include a support column frame 370, a block 210, a movable bracket 220 and a lift mechanism 372. The block 210 can be coupled to the lower end of the support column frame 370. The block 210 can be useful to couple the support column 20 to a structure (e.g., a wheeled base, wall, or the like).

The lift mechanism 372 can be coupled between the support column frame 370 and the movable bracket 220. The lift mechanism 372 can assist the translation of the movable bracket 220 relative to the support column frame 370. In some example configurations, the lift mechanism 372 can include a weight counterbalance mechanism 373. The weight counterbalance mechanism 373 can be configured to lift at least a portion of the combined weights attached to the movable bracket 220.

The weight counterbalance mechanism 373 can include a wheel assembly 374. The wheel assembly 374 can be rotatingly coupled to the support column frame 370. The wheel assembly 374 can rotate relative to the support column frame 370 around a horizontal axis during the translation of the movable bracket 220. In some example configurations, the wheel assembly 374 can include a pulley 375 and a rotary cam 376 fixedly attached to the pulley.

In some example configurations, one or more tensile members 378 (e.g., a cable, a rope, or the like) can engage with the wheel assembly 374. Translation of the movable bracket 220 can activate (e.g., move, rotate, or the like) the one or more tensile members 378 and the wheel assembly 374. The one or more tensile members 378 can be coupled to a biasing member 379 (e.g., a spring, or the like). The biasing member 379 can be activated (e.g., stretched, expanded, retracted, compressed, or the like) when the movable bracket 220 translates relative to the support column frame 370. In an example, the lift mechanism 372 can be similar to (and can incorporate components of) the lift mechanism described in commonly assigned U.S. Pat. No. 11,071,377 to Lindblad et al., entitled “HEIGHT ADJUSTABLE PLATFORMS AND ASSOCIATED MECHANISMS”, which is hereby incorporated by reference herein in its entirety

FIG. 30 is front view of another example configuration of the current disclosure. Portions of the support column 20 (e.g., a front face 25) have been hidden for clarity. In some configurations, the support column 20 can include a linear actuator 380. The linear actuator 380 can be coupled between the support column frame 370 and the movable bracket 220. The linear actuator 380 can be used for adjusting a height of the movable bracket 220 relative to the support column frame 370. The linear actuator 380 can be coupled to an electric motor 381. In some example configurations, the electric motor can be housed inside the block 210. In other configurations, the electric motor 381 can be directly coupled to the support column frame 370. The electric motor 381 can drive the linear actuator 380.

One or more control buttons (not shown) can be used to activate the linear actuator 380. In some configurations, the one or more control buttons can be located on the head unit assembly 10 close to the handle 14 (e.g., proximate to a first handle member 391 of FIG. 32). In other configurations, the one or more control buttons can be located on a graphical user interface shown on a display 442 (shown in FIG. 37). The one or more control buttons can be operationally coupled to the electric motor 381. Once activated through the one or more control buttons, the electric motor 381 can drive the linear actuator 380 to adjust a height of the movable bracket 220.

FIG. 31 is a perspective view of a workstation 130 according to another example configuration of the current disclosure.

The first display mounting assembly 60A and the second display mounting assembly 60B can be useful to hold a first display (not shown) and a second display (not shown) above the worksurface 13. The first display and the second display can be similar to the display 442 (shown in FIG. 37). In some configurations, one or both of the first display mounting assembly 60A and the second display mounting assembly 60B can include a lift mechanism (e.g., similar to the second height adjustment mechanism 499 shown in FIG. 41) to adjust a position of the one or both of the first display and the second display relative to the worksurface 13. In other configurations, the first display mounting assembly 60A and the second display mounting assembly 60B can be stationary (e.g., a pole without a lift mechanism).

In some example configurations, the first display mounting assembly 60A and the second display mounting assembly 60B can be independent of each other. For example, the first display coupled to the first display mounting assembly 60A and the second display coupled to the second display mounting assembly 60B can be independently height adjustable. In other configurations, the first display mounting assembly 60A and the second display mounting assembly 60B can be coupled to each other using a crossbar (not shown). In this configuration, a height of two displays coupled to the first display mounting assembly 60A and the second display mounting assembly 60B can be adjusted simultaneously.

FIGS. 32-33 are an upper and a lower perspective views of the head unit assembly 10 of FIG. 1. The head unit assembly 10 can include a handle 14 coupled to a head unit chassis 265. The handle 14 can be used for dual purposes; (1) as a handle for transferring the workstation (e.g., the workstation 100 of FIG. 1) form a first place to a second place within a facility, and (2) as a bumper for protecting the workstation 100 against impact while transferring it through the facility (e.g., passing through doorways, or the like). The handle 14 can be made of known impact resistant, durable, soft engineering materials including, but not limited to, extruded aluminum, die cast aluminum, molded plastic, ABS, or the like.

In some example configurations, the handle 14 can have a first handle member 391 and a second handle member 392. The first handle member 391 can be located proximate to the front end 11 of the head unit assembly 10, and the second handle member 392 can be located proximate to the rear end 12 of the head unit assembly 10. The first handle member 391 and the second handle member 392 can be coupled to the head unit chassis 265 using one or more connectors 395 (for example, one or more connectors 395 can be located in each corner of the head unit chassis 265). The one or more connectors 395 can be coupled to the head unit chassis 265 and coupled to the first handle member 391 and the second handle member 392 to securely connect the handle 14 to the head unit chassis 265.

The handle 14 can further include a third handle member 393 and a fourth handle member 394. The third handle member 393 and the fourth handle member 394 can extend in a transverse direction to the first handle member 391 and the second handle member 392. The third handle member 393 can be located on one side of the head unit assembly 10 and the fourth handle member 394 can be located on the other side of the head unit assembly 10. A corner member 396 can be coupled to each end of the third handle member 393 and the fourth handle member 394. The corner members 396 can be used to couple the third handle member 393 and the fourth handle member 394 to the first handle member 391 and the second handle member 392 as illustrated in FIG. 32.

In some example configurations, the first handle member 391 and the second handle member 392 can be made longer than a width of the head unit chassis 265 to create a space 397 for attaching accessories to the sides of the head unit chassis 265 as illustrated in FIGS. 1-2. In other example configurations, the length of the first handle member 391 and the second handle member 392 can be close to a width of the head unit chassis 265 to reduce the overall footprint of the workstation (e.g., the workstation 100 of FIG. 1). In yet another example configuration, the first handle member 391 and the second handle member 392 can be made in adjustable lengths (e.g., a telescoping tubular structure, or the like). The user of the workstation 100 can adjust the lengths of the first handle member 391 and the second handle member 392 to create the space 397 for attaching various accessories to the head unit chassis 265.

The head unit assembly 10 can include one or more T-slot brackets 400. The one or more T-slot brackets 400 can be coupled to the one or both sides of the head unit chassis 265. The one or more T-slot brackets 400 can have an elongated structure extending between a first connector 395A and a second connector 395B. The one or more T-slot brackets 400 can have a first T-slot 404 formed on an outside surface 405 of the one or more T-slot brackets 400. The first T-slot 404 can extend at least a portion of a length of the one or more T-slot brackets 400 between the first connector 395A and the second connector 395B. The first T-slot 404 can be used to couple one or more accessories 18 to the head unit assembly 10 on the side of the worksurface 13 (e.g., outside the head unit chassis 265). In some configurations, a second T-slot 406 can be formed on an inner surface 407 of the one or more T-slot brackets 400. The second T-slot 406 can be used to couple accessories to the head unit assembly 10 under the worksurface 13 (e.g., inside the head unit chassis 265).

FIG. 34 is a rear perspective view of a workstation 140 according to an example configuration of the current disclosure.
