Definitions

  • the present invention relates to standing desks designed for use by people while standing and to techniques for reducing fatigue caused by standing for prolonged periods.
  • height-adjustable tables provide a heavy base of support that allow a user to alternate between standing and sitting positions to use the table.
  • the table can be lowered to a sitting level or raised to a standing level using an electronic controller or hand crank when desired.
  • Occupational studies have demonstrated short-term benefits associated with the use of height-adjustable tables when provided to workers in an office setting, including increased office productivity, reduced low back pain, and reduced absenteeism (Nerhood and Thompson, 1994).
  • height adjustable tables are provided to office workers, a majority of office work participants prefer the height adjustable table over a normal desk (Hedge and Ray, 2004). But these studies also show that the use of stand-up desks tends to rapidly decline after about a month—likely because people may not tolerate standing all day.
  • a dynamic standing desk comprising a work surface configured to move with planar motion parallel with the ground and with a range of movement that adjusts as a function of the size of a user of the desk.
  • a method of reducing lower musculoskeletal discomfort of a user of a standing desk comprising the step of oscillating a work surface of the desk with a range of movement based on a length of a limb of the user.
  • the standing desk may include one or more of the following features, either singly or any technically-feasible combination.
  • a dynamic standing desk may be provided with a table base and attached tabletop which is controlled electronically and moveable independently both in the X (left-right) and Y (anterior-posterior) directions.
  • the table base may be height-adjustable, controlled manually or electronically, so that it is moveable in the Z-direction (up-down).
  • Programmable continuous unidirectional or multidirectional XY movements or patterns of movements of the tabletop encourage or require a user of the desk to continuously take small steps in order to remain centered in front of the tabletop.
  • An optional in-cut or cutout in the tabletop allows for additional human user step cueing.
  • the tabletop is continuously or intermittently moveable and can be programmed with a predetermined rate of movement and range of movement in the X- and/or Y-directions or variable combinations of these. These parameters of tabletop movement can be input via a tabletop-mounted or remote Human Interface Device (HID).
  • Planar XY tabletop movement can be enabled by mounting the tabletop on independent support bases movable in the X and Y directions.
  • X and Y support base movement may be established through linear actuators directly moving the X and Y support bases, via rotary actuators moving the X and Y tabletop support bases by cogwheel or other directional switch transfer of rotary movement to linear movement, or other mechanisms of displacement.
  • the desk may include one or more controllers and electronic memory for collecting the user's stepping physical activity measurements either wired or wireless from body-attached accelerometers and other activity measurement devices.
  • the desk may be configured to provide visual feedback of the user's activity levels, such as via an electronic display.
  • the standing desk may be used with an anti-fatigue mat on which the user stands during use of the desk. Such a mat may be part of the dynamic standing desk itself or may be separately provided.
  • An optional desk-attached fall-prevention belt attachment system may also be provided.
  • Another available safety feature is the use of individualized start-up and use of the dynamic standing desk based on user-worn sensors, such as radiofrequency identification (RFID) tagging, and desk-mounted sensors that track the height of the table and will allow automatic shut-off once the individual users stops using the desk.
  • RFID radiofrequency identification
  • the tabletop of the desk can be vertically adjusted to the particular human user's individual height preference or preference to intermittent alternations between sitting and standing.
  • the dynamic standing desk may be an effective solution to combat sedentariness, the quick development of musculoskeletal discomfort when standing at a stationary height-adjustable workstation, and/or inactivity and prolonged sitting in populations with conditions that affect mobility or energy expenditure during physical activity and that generally benefit from low-intensity physical activity.

  • a dynamic standing desk capable of reducing musculoskeletal fatigue normally caused by prolonged standing.
  • the desk has a movable work surface that causes the user to repeatedly shift their body weight and alter their posture, thereby providing the health and productivity benefits of a standing position without the discomfort that normally sets in after standing for prolonged periods in a static posture.
  • FIG. 1 is an isometric view of an exemplary dynamic standing desk 10 , which includes a base 12 , a tabletop 14 (shown in cutaway view), and a coupling assembly 16 that movably couples the tabletop with the base.
  • a work surface 18 at the top side of the tabletop 14 is configured to move with planar motion parallel with the ground or floor i.e., in an x-y plane of FIG. 1 . This movement is with respect to the ground, the base 12 , and with a user standing at the desk 10 .
  • the planar motion has a range of movement that adjusts as a function of the size of the user of the desk 10 , as discussed in further detail below.
  • the work surface 18 of the tabletop 14 may be generally flat and designed to support items such as a desktop or laptop computer, computer monitor, video screen, and, at times, part of the weight of the user.
  • the illustrated tabletop 14 is generally rectangular with an optional vertical wall extending downward away from the work surface 18 at its perimeter. A cavity or recess is can thus be formed beneath the work surface 18 , which houses the coupling assembly 16 and/or other components. Other non-rectangular work surfaces are possible, such as more oval or shell-shape configurations.
  • the tabletop 14 may additionally include a cut-out 20 along its perimeter as a visual or tactile cue to the user as to where to stand when using the desk 10 .
  • the cut-out 20 can be made deeper into the tabletop 14 so that the user is partly surrounded by the work surface 18 .
  • the effective depth of the cut-out 20 is enhanced by extensions 22 in the y-direction (see FIG. 3 ). Deep cut-outs 20 and/or extensions 22 can provide movement cues to the user to prompt them to shift their weight away from a part of the tabletop 14 that has moved closer to the user during use.
  • the coupling assembly 16 includes a frame 24 , one or more first guide sets 26 , and one or more second guide sets 28 .
  • the illustrated frame 24 is rectangular with a symmetric cross-shape connecting its pairs of opposite sides.
  • One half of each of the guide sets 26 , 28 is rigidly mounted to the frame 24 .
  • Each of the first guide sets 26 includes a guide 34 and a follower 36 .
  • the guides 34 in this case are rails with a U-shaped channel and are rigidly mounted to the frame 24 .
  • the followers 36 are sliders rigidly mounted to the tabletop 14 with downward-facing protrusions complimentary in shape with the guide channels.
  • the first guide sets 26 thus provide a single linear degree of freedom of movement between the tabletop 14 and the frame 24 and restrict movement of the tabletop 14 relative to the frame 24 in other directions. In other words, the first guide sets 26 permit movement of the tabletop 14 with respect to the frame 24 in a first (x) direction and prevent relative movement of the tabletop 14 and frame 24 in a different second (y) direction.
  • one of the actuators 30 is configured to provide movement of the tabletop 14 with respect to the base 12 in the first (x) direction.
  • the illustrated actuator 30 is an electric motor rigidly mounted to the frame 24 with its axis of rotation oriented parallel with the y-axis. Rotational motion of the actuator 30 is converted to linear motion via a transmission, which in this case includes a pinion or worm gear mounted to the motor shaft and engaged with a toothed linear rack rigidly mounted to the tabletop 14 .
  • the other actuator 32 ( FIG. 2 ) is configured to provide movement of the frame 24 —and, thereby, the tabletop 14 —with respect to the base 12 in the second (y) direction.
  • the illustrated actuator 32 is an electric motor rigidly mounted to the base 12 with its axis of rotation oriented parallel with the z-axis. Rotational motion of the actuator 32 is converted to linear motion via a transmission, which in this case includes a pinion or worm gear mounted to the motor shaft and engaged with a toothed linear rack rigidly mounted to the frame 24 .
  • a transmission which in this case includes a pinion or worm gear mounted to the motor shaft and engaged with a toothed linear rack rigidly mounted to the frame 24 .
  • This configuration provides independently controllable movement of the work surface 18 in two perpendicular directions parallel with the ground, including simple mediolateral (left-to-right) movement, simple anteroposterior movement, and any combination of those movements, such as circular, elliptical, or oblique movement in an x-y plane.
  • the illustrated configuration also permits the x- and y-guide sets 26 , 28 to be located within the same layer of the stack-up of the coupling assembly 16 .
  • the weight of the tabletop 14 is borne by bearings 42 mounted along the base 12 .
  • the illustrated coupling assembly 16 is merely illustrative and can be embodied in numerous variations, such as with the x- and y-directions switched, the guides and followers inverted, the uses of linear actuators and/or omission of transmission components, etc.
  • the desk of FIG. 3 is a variation of the desk of FIG. 2 in which the guide sets 26 , 28 are oriented with the U-shaped channels opening in the horizontal rather that the vertical direction.
  • Both the range of movement and the rate of movement of the work surface 18 relative to the ground are controllable and adjustable. More particularly, the range of movement of the work surface 18 is adjusted as a function of the size of the user of the desk 10 . It has been determined that particular amounts and rates of work surface movement relative to the user can reduce musculoskeletal discomfort enough to encourage the user to remain in the standing position longer than they otherwise would and to continue daily use of the standing desk for weeks or months longer than they otherwise would.
  • the “range of movement” of the work surface 18 or tabletop 14 is the extent of movement in an arbitrary direction in the XY plane before the work surface at least partially reverses direction. Generally speaking, the optimal ranges of movement are relatively greater for relatively tall users and relatively less for relatively short users.
  • the optimal ranges of movement are related to the length of one of the user's limbs.
  • the optimal ranges of movement of the work surface relative to the user is a function of the length (L) of a leg of the user or the average length of the legs of the user. This length (L) can be measured from the center of the hip joint to the heel of the user or from the anterior superior iliac spine to the medial malleolus.
  • the work surface 18 is configured to move relative to the user with a range of movement equal to an amount between 25% and 35% of the length (L) of the leg of the user. In another embodiment, the range of movement is equal to an amount between 55% and 65% of the length (L) of the leg of the user. In another embodiment, the range of movement is exclusive of amounts between 40% and 50% of the length (L) of the leg of the user.
  • the range of tabletop movement may be measured in the mediolateral (x) direction and/or the anteroposterior (y) direction.
  • the rate of movement of the work surface 18 with respect to the user may be in a range from 2 mm/sec to 10 mm/sec in any planar direction, or between 2 mm/sec and 7 mm/sec in the mediolateral (x) direction and/or the anteroposterior (y) direction.
  • the rate of movement in the mediolateral (x) direction and/or the anteroposterior (y) direction is between 6 mm/sec and 7 mm/sec.
  • the standing desk 10 may further include a controller 44 configured to receive information pertinent to the size of the user and to set the range of movement based on the received information.
  • the controller 44 can receive this information (e.g., length of user leg information) from a variety of sources, such as a human interface device (HID), a dial or switch, a sensor, a measurement device, a communication device such as a wireless transceiver, or from computer memory.
  • the standing desk 10 includes a sensor that determines the resonant frequency of an RFID tag carried by the user.
  • the controller 44 receives the information from the sensor, matches it to a known user stored in computer memory, and sets the range of movement based on the known leg length of that user.
  • a vision system is used to determine the leg length of the user with the controller subsequently receiving that information and using it to set the range of movement.
  • the leg length of the user is entered by the user or another person manually, such as via touch screen, keyboard, or dial setting, or by voice command, and the controller 44 receives the information and sets the range of movement accordingly.
  • the presence or absence of the user may also be determined by the controller with the actuators being deactivated in the absence of the user.
  • Other types of sensors such as motion or proximity sensors can be used to provide this safety function.
  • a tether or safety harness may also be used to attach the user to the desk or to a nearby structure for further safety.
  • FIG. 3 illustrates a user from behind while performing tasks at an exemplary dynamic standing desk 10 .
  • the user shifts their weight from left (a) to center (b) to right (c) while using the desk. While this may occur naturally when the user is at a static standing desk, the frequency of weight shifts and postural adjustments in that case may generally be based on discomfort; that is to say that the user shifts weight and changes posture to move from a posture that has already become uncomfortable to a different more comfortable posture. In other words, the frequency is too low or triggered too late to prevent the initial discomfort from being experienced. If the user shifts their weight more frequently—i.e., prior to discomfort setting in—the standing position is tolerable for extended periods of time.
  • the dynamic standing desk and the controlled movement of the work surface as a function of the size of the user forces the user to shift weight and change posture more frequently and from the beginning of desk use.
  • FIG. 4 illustrates another embodiment of the standing desk 10 and is a bottom view of the tabletop 14 and coupling assembly 16 .
  • the first and second actuators 30 , 32 are linear.
  • the frame 24 is embodied by x-direction guide rails 34 and y-direction guide rails 38 , all of which move together.
  • the frame 24 moves in the x-direction only with respect to the tabletop 14 under the power of the first actuator. Independently, the frame 24 moves in the y-direction only with respect to the base 12 . Additional views are illustrated in FIGS. 5 and 6 .
  • Use of the dynamic standing desk may be referred to as a “step-and-work” auto-exercise or “step-and-treat” clinical rehabilitation and is a time- and cost-effective lifestyle modification to facilitate lower extremity or body weight shifting movements.
  • Targeted users are, but not limited to, office workers, fitness workers, or clinical rehabilitation patients, including those with metabolic or neurological disorders that affect gait and balance functions.
  • Users stand at the desk with an automatically moving tabletop that moves in the transverse plane (X-Y movements). The range of X-Y movements can be adjusted such that the tabletop moves away farther than practical physical arm length use when using, for example, a keyboard. Tabletop movement necessitates physical and bodyweight shifting adjustment steps by the user to stay centered in front of the work surface.
  • the dynamic standing desk will generate variable work surface movement parameters—i.e., from slow to fast in terms of rate of movement, from continuous to discontinuous work surface movement, and from smaller to larger ranges of displacements.
  • Relatively slow rates of movement will provide more smooth and slow stepping movements and will allow non-disrupted visual focus on an object on the desk, such as a display screen.
  • Slow rates of movement will also allow non-disrupted use of a small object on the desk, such as a computer mouse, and will not interfere with handwriting, for example.
  • Faster rates of movement and/or large ranges of movement of the work surface will increase the physical activity of the user.
  • Bidirectional or multidirectional displacements will induce weight-shifting stepping movements with truncal adjustments for the user.
  • the dynamic standing table will increase physical activity and mobility compared to the sitting position and prevent or slow down the development of musculoskeletal discomfort associated with prolonged static body positions.
  • the dynamic standing table can allow the user to maintain a stable eye-to-computer screen position and distance, which will allow continued fine oculomotor desktop activities. This may prevent cognitive cost and ocular strain effects while using a desktop computer or screens.
  • Advantages and features of the dynamic standing desk disclosed herein may include the programmable human use movable tabletop for office, personal, recreational, or clinical therapy uses.
  • Built-in physical activity monitoring functions and monitoring systems can provide the user's advantageous functions of losing weight, improving energy and fitness functions, improving mobility and balance, maintaining cognitive productivity, and preventing or reducing musculoskeletal and mental fatigue and stress symptoms.
  • a height-adjustable (e.g., electrical, hydraulic, or hand-cranked) table base may include, among other components, a moveable tabletop, a software-controlled programmable controller, a physical activity measurement device (e.g., user-mounted accelerometer), feedback device (e.g., electronic display or auditory information), and an optional tabletop cut-out or attached or cut-out physical cueing device.
  • Tabletop XY planar movement can be established by mounting the tabletop on independent support bases movable in the X and Y directions.
  • X and Y support base movement can established via linear actuators directly moving the X and Y support bases or rotary actuators or other motors moving the X and Y support bases by cogwheel transfer of the rotary movement to linear movement or other mechanisms of displacement.
  • the tabletop is continuously or intermittently moveable and positioned with a predetermined rate and range of X and/or Y movement. These parameters may be input via a tabletop-mounted or remote computer and/or controller containing human-user activated software selections.
  • the computer and/or controller may include an input/output assembly that can be mounted to the tabletop or controlled remotely via wireless control.
  • the computer may include components (e.g., numerical, light, voice, video-type or touch-screen buttons and displays) that enable the user to input control command to the actuator and/or actuator controller and to receive feedback regarding an exercise or use session (e.g., calories burned, distance traveled, heart rate, time elapsed, time remaining, limb and truncal movements, etc.).
  • the moveable tabletop may include at least one top layer (e.g., the work surface layer) with or without a variable number of one to two or more support layers (e.g., the coupling assembly). Displacement of one layer relative to the base can include a sliding, gliding, wheeled, cogwheeled, or gear-based mechanical translation or rotation mechanism.
  • Variants of the dynamic standing table include an X-X′ oscillating tabletop capable of exclusive left-to-right bidirectional movement relative to the user, or a Y-Y′ oscillating tabletop capable of exclusive anterior-to-posterior bidirectional movement relative to the user.
  • the construction of an exclusively X-X′ or Y-Y′ oscillating tabletop will be simplified compared to a multi-directional moving tabletop, as they do not require the extra materials (e.g., actuators) and/or translation layer for the opposite direction.
  • the dynamic standing desk has been found to provide physical activity in users while at the same time reducing development of musculoskeletal discomfort and providing health benefits compared to regular height-adjustable standing desk use and sitting in healthy adults.
  • FIG. 7 is a chart illustrating total musculoskeletal discomfort, as rated by healthy adult participants, as a function of time in three different conditions: sitting, static standing at a desk, and standing at the dynamic standing desk.
  • each participant completed three 4-hour sessions, including the baseline sitting session first, followed by either a static desktop standing session or a dynamic desktop standing session. The third session was whichever of the static or dynamic sessions that had not yet been completed.
  • the dynamic standing desk may therefore be beneficial to populations that perform desktop work in prolonged sitting positions, such as office workers, and especially to those individuals who inherently stand rather statically and/or require cues to make postural adjustments to maximize physical activity.
  • Other populations that may benefit from the dynamic standing desk are those with conditions that affect mobility, and as such, tend to be inactive. In such patient populations, standing can have positive effects in terms of physical functioning, strength, and balance compared to the detrimental effects of sedentariness.
  • FIG. 11 is a chart illustrating total musculoskeletal discomfort, as rated by older adult diabetic participants, as a function of time in three different conditions: sitting, static standing at a desk, and standing at the dynamic standing desk.
  • each participant completed three 4-hour sessions, including the baseline sitting session first, followed by either a static desktop standing session or a dynamic desktop standing session.
  • the third session was whichever of the static or dynamic sessions that had not yet been completed. Oxygen consumption and overall movements by the test subjects progressively increased from sitting to static standing to dynamic standing desk use (p ⁇ 0.001).
  • the dynamic standing desk has also been shown to extend clinical effects of physical therapy in physically deconditioned persons afflicted with age or disease-related conditions affecting mobility, such as persons with Parkinson's disease.
  • a clinical rehabilitation dynamic standing desk may augment or extend the early clinical gain of physical therapy to serve as a post-physical therapy extension or supplementation that can be provided in the home of the person with the mobility condition with long-term sustained clinical benefits and without serious adverse effects.
  • data from a clinical trial in patients with Parkinson's disease who had gait and balance disturbances received 12 sessions of physical therapy, after which the patients improved on walking and balance control (functional mobility) measures, such as the Timed Up and Go (TUG) test and walking time at the time of completion of the therapy.
  • the patients were then randomized into one of two groups. One group used a dynamic standing desk at home after completion of physical therapy, while the other group use no desk at home (the usual care) for a 4-month post-physical therapy extension period. Clinical assessment was repeated at the end of the 4-month extension period and compared to assessments prior to and at the time of completion of the physical therapy.
  • the dynamic standing desk may thus provide one of more of the following benefits:
  • the terms “e.g.,” “for example,” “for instance,” “such as,” and “like,” and the verbs “comprising,” “having,” “including,” and their other verb forms, when used in conjunction with a listing of one or more components or other items, are each to be construed as open-ended, meaning that the listing is not to be considered as excluding other, additional components or items.
  • Other terms are to be construed using their broadest reasonable meaning unless they are used in a context that requires a different interpretation.
  • the term “and/or” is to be construed as an inclusive OR.
  • phrase “A, B, and/or C” is to be interpreted as covering all of the following: “A”; “B”; “C”; “A and B”; “A and C”; “B and C”; and “A, B, and C.”
