Definitions
- This application relates generally to ergonomic workplace environments, and more particularly, to an adjustable desk platform or desk.
- Sitting for long periods of time during the work day is generally not good for one's health and wellness. Medical studies show that sitting increases the rate of all-cause mortality, especially from cardiovascular disease, diabetes and obesity, for example. People who sit for most of the day are 50 percent more likely to die of heart attacks. Even if you exercise, the longer you sit the greater the chances you will die. Sitting shuts down the circulation of the fat-absorbing enzyme lipase, while standing up engages muscles and promotes the distribution of lipase, which prompts the body to process fat and cholesterol, independent of the amount of time spent exercising.
- Taking regular breaks from sitting for prolonged periods of time can have several positive outcomes. For example, standing can provide more energy during the work day. In addition, because standing burns more calories than sitting, standing can also result in weight loss without changes in diet or exercise. It is also harder to become more tired or lose focus when standing.

- supporting rod 61 can be connected with the primary pivot arm 31 of each pivot arm set 30, and reinforcement 62 can be connected with the secondary pivot arm 32 of each pivot arm set 30.
- the reinforcement member can fix the side-to-side distance between the pivot arms and add stability, avoiding side-to-side movement when lifting or lowering upper platform 10 from lower platform 20, and can make the adjustable platform operate smoothly.
- the user When in use, the user can place the adjustable desk platform on to a desktop, and may place items on the upper platform 10 as desired, such as, without limitation, a computer, documents, desk lamps, instruments, and supplies.
- the user can adjust the height between the upper platform 10 and the lower platform 20 according to their working posture and/or other needs.
- Figure 3 depicts the adjustable desk platform in a fully raised position.
- the user in order to lower the adjustable desk platform, the user can pull handle 42, which in turn displaces the first linkage 431, second linkage 432, and third linkage 433. This can, in turn, retract the anchor 41 and cause the anchor to withdrawal from the perforation(s) 3111 of the primary pivot arm 31.
- the pivot arm 31 is released from a substantially fixed position, allowing primary pivot arm 31 and secondary pivot arm 32 to move, consequently allowing the upper platform 10 to move with respect to the lower platform 20.
- the distance between upper platform 10 and lower platform 20 can be reduced, for example, to the fully lowered position shown in Figure 11 , or to some position between the fully raised position and the fully lowered position. This allows the distance between the upper platform 10 and lower platform 20 to be easily set and adjusted.
- the boss 321 slides within arc slot 211 of the upper mounting bracket 21, and accordingly, stretches or relaxes the compression spring 51 of the corresponding biasing mechanism 50.
- pivot point 54 leans against the bottom side of booster spring 53, when upper platform 10 and lower platform 20 are moved toward the fully lowered position, boss 321 can press laterally against the booster springs 53, thereby causing booster spring 53 to bend.
- the booster springs 53 can provide additional upward bias when the upper platform 10 is in or near the fully lowered position.
- the user when the user desires to increase the distance between the lower platform 20 and the upper platform 10, the user can pull the handle(s) of the locking set(s) 40 to impact locking set 40, springs 44, and anchors 41, causing anchors 41 to retract from the perforation 3111 and hole 111, releasing the primary and secondary pivot arms 31, 32 so the spacing between the upper platform 10 and the lower platform 20 can be increased.
- lowering the upper platform 10 causes the pivot arm sets 30 to pivot with respect to the upper mounting brackets 21.
- the resultant rotation of the secondary pivot arms 32 causes the respective bosses 321 to slide within the respective arc slots 211, thereby stretching the respective compression springs 51 of the biasing mechanisms 50, providing a measure of resistance against lowering of the upper platform 10.
- bosses 321 slowly pull away from the respective booster springs 53, and allows the booster springs 53 to retract to their natural, unbent state.
- Increasing the weight on upper platform 10 can increase the difficulty of raising the upper platform 10 from the lower platform 20. Due to the configuration of the biasing mechanism 50, booster spring 53, and pivot point 54, when upper platform 10 is raised from the lower platform 20, the elastic force of booster spring 53 and spring 51 can influence the boss 321 of each secondary pivot arm 32, causing secondary pivot arm 32 to generate an upward lifting force, reducing the amount of effort required from the user to raise the upper platform 10.
- the overall center of gravity of the adjustable desk platform can shift between lower platform 20 and upper platform 10, especially when various items are placed on top of upper platform 10. Because items located on the upper platform create additional weight, the overall center of gravity of the adjustable desk platform will quickly shift to the upper platform 10, and potentially make the adjustable desk platform unstable. Accordingly, the counterweight(s) 22 can increase the weight of lower platform 20, thereby helping to counterbalance the weight of the upper platform 10 when in the raised position and/or when weighted with items.
- housings 23 of upper platform 10 and the housings 46 of locking set 40 can help protect the user's fingers or other foreign matter from being caught in the locking sets 40, the pivot arm sets 30, and/or inside of the biasing mechanisms 50. Housings 23 and housings 46 can also add to the aesthetic appearance of the adjustable desk platform.

Description
- This application relates generally to ergonomic workplace environments, and more particularly, to an adjustable desk platform or desk.
- Sitting for long periods of time during the work day is generally not good for one's health and wellness. Medical studies show that sitting increases the rate of all-cause mortality, especially from cardiovascular disease, diabetes and obesity, for example. People who sit for most of the day are 50 percent more likely to die of heart attacks. Even if you exercise, the longer you sit the greater the chances you will die. Sitting shuts down the circulation of the fat-absorbing enzyme lipase, while standing up engages muscles and promotes the distribution of lipase, which prompts the body to process fat and cholesterol, independent of the amount of time spent exercising.
- There are desks available to be used while standing, and even desks adapted for use while a user is on a treadmill. However, standing for very long periods of time to work is more tiring, dramatically increases the risks of carotid atherosclerosis because of the additional load on the circulatory system, and increases the risks of varicose veins.
- Taking regular breaks from sitting for prolonged periods of time can have several positive outcomes. For example, standing can provide more energy during the work day. In addition, because standing burns more calories than sitting, standing can also result in weight loss without changes in diet or exercise. It is also harder to become more tired or lose focus when standing.
- Because regular breaks from sitting are beneficial, and because many people during the work day want to remain productive while taking breaks from sitting, and because everyone will sit and stand for different lengths of time at different times during the day, there exists a need to create a work environment that is ergonomic for someone standing as well as sitting, and allows the transition to be easy, quick, and simple.

Eachsupport 52 andbooster spring 53 of biasingmechanism 50 is connected withlower platform 20.Arc slot 211 can be selectively connected with the respectivesecondary pivot arm 32 on the other side of the respective upper mountingbracket 21.Pivot point 54 can be located against the bottom side ofbooster spring 53, Eachbiasing mechanism 50 can be located between the respective upper mountingbracket 21 andhousing 23, thereby concealing thebiasing mechanism 50. - As shown in
Figure 4 ,reinforcement member 60 may extend between the left and right pivot arm sets 30. According to an embodiment, reinforcement member may include a supporting rod 61 and aseparate reinforcement 62, however, other single-member and multi-member embodiments are possible. According to an embodiment, supporting rod 61 can be connected with theprimary pivot arm 31 of each pivot arm set 30, andreinforcement 62 can be connected with thesecondary pivot arm 32 of each pivot arm set 30. According to embodiments, the reinforcement member can fix the side-to-side distance between the pivot arms and add stability, avoiding side-to-side movement when lifting or loweringupper platform 10 fromlower platform 20, and can make the adjustable platform operate smoothly. - When in use, the user can place the adjustable desk platform on to a desktop, and may place items on the
upper platform 10 as desired, such as, without limitation, a computer, documents, desk lamps, instruments, and supplies. The user can adjust the height between theupper platform 10 and thelower platform 20 according to their working posture and/or other needs. -
Figure 3 depicts the adjustable desk platform in a fully raised position. Referring toFigures 3 ,8-10 , and12 , in order to lower the adjustable desk platform, the user can pull handle 42, which in turn displaces thefirst linkage 431,second linkage 432, andthird linkage 433. This can, in turn, retract theanchor 41 and cause the anchor to withdrawal from the perforation(s) 3111 of theprimary pivot arm 31. As a result, thepivot arm 31 is released from a substantially fixed position, allowingprimary pivot arm 31 andsecondary pivot arm 32 to move, consequently allowing theupper platform 10 to move with respect to thelower platform 20. Accordingly, the distance betweenupper platform 10 andlower platform 20 can be reduced, for example, to the fully lowered position shown inFigure 11 , or to some position between the fully raised position and the fully lowered position. This allows the distance between theupper platform 10 andlower platform 20 to be easily set and adjusted. - As shown In
Figures 3 and8-11 , when the user moves theupper platform 10 andlower platform 20 to a desired height relative to each other, the user can release the handle(s) of locking set(s) 40. As a result, the retraction force ofsprings 44 of each locking set 40 can move thesecond linkage 432, causingfirst linkage 431 andthird linkage 433 to move sequentially, thereby causinganchors 41 to lock through the hole 111 of the lower mounting bracket and the correspondingperforations 3111 onprimary pivot arm 31. This, in turn, locks the position of theupper platform 20 relative to thelower platform 10. - As shown in
Figures 3 ,10 , and11 , as the primary andsecondary pivot arms bracket 21, theboss 321 slides withinarc slot 211 of the upper mountingbracket 21, and accordingly, stretches or relaxes thecompression spring 51 of thecorresponding biasing mechanism 50. Referring toFigure 11 , sincepivot point 54 leans against the bottom side ofbooster spring 53, whenupper platform 10 andlower platform 20 are moved toward the fully lowered position,boss 321 can press laterally against the booster springs 53, thereby causingbooster spring 53 to bend. Thus, according to the invention, the booster springs 53 can
provide additional upward bias when theupper platform 10 is in or near the fully lowered position. - As shown in
Figures 3 ,8, 9 , when the user desires to increase the distance between thelower platform 20 and theupper platform 10, the user can pull the handle(s) of the locking set(s) 40 to impact locking set 40, springs 44, and anchors 41, causinganchors 41 to retract from theperforation 3111 and hole 111, releasing the primary andsecondary pivot arms upper platform 10 and thelower platform 20 can be increased. - As shown in
Figures 3 ,10 , and11 , lowering theupper platform 10 causes the pivot arm sets 30 to pivot with respect to the upper mountingbrackets 21. The resultant rotation of thesecondary pivot arms 32 causes therespective bosses 321 to slide within therespective arc slots 211, thereby stretching the respective compression springs 51 of the biasingmechanisms 50, providing a measure of resistance against lowering of theupper platform 10. When the distance between theupper platform 10 and thelower platform 20 is gradually increased from the fully lowered position,bosses 321 slowly pull away from the respective booster springs 53, and allows the booster springs 53 to retract to their natural, unbent state. - Increasing the weight on upper platform 10 (e.g., by placing an item on the upper platform 10) can increase the difficulty of raising the
upper platform 10 from thelower platform 20. Due to the configuration of thebiasing mechanism 50,booster spring 53, andpivot point 54, whenupper platform 10 is raised from thelower platform 20, the elastic force ofbooster spring 53 andspring 51 can influence theboss 321 of eachsecondary pivot arm 32, causingsecondary pivot arm 32 to generate an upward lifting force, reducing the amount of effort required from the user to raise theupper platform 10. - When lifting
upper platform 10, the overall center of gravity of the adjustable desk platform can shift betweenlower platform 20 andupper platform 10, especially when various items are placed on top ofupper platform 10. Because items located on the upper platform create additional weight, the overall center of gravity of the adjustable desk platform will quickly shift to theupper platform 10, and potentially make the adjustable desk platform unstable. Accordingly, the counterweight(s) 22 can increase the weight oflower platform 20, thereby helping to counterbalance the weight of theupper platform 10 when in the raised position and/or when weighted with items. - According to embodiments, the
housings 23 ofupper platform 10 and the housings 46 of locking set 40 can help protect the user's fingers or other foreign matter from being caught in the locking sets 40, the pivot arm sets 30, and/or inside of the biasingmechanisms 50.Housings 23 and housings 46 can also add to the aesthetic appearance of the adjustable desk platform. - Referring to
Figures 1 and2 , the adjustable desk platform can include akeyboard tray 70. Thekeyboard tray 70 can be detachably connected withlower platform 20.Keyboard tray 70 includes atray portion 71 and one or more releasable joint component(s) 72. According to an embodiment, twojoint components 72 can be connected on opposed sides oftray portion 71. Thejoint components 72 can be slidably mounted on thelower platform 20. Additionally or alternatively, thejoint components 72 can be drilled in thehousing 23 oflower platform 20. The joint components are not limited to the embodiments show, and other connectors known in the art can be used as alternatives.
When desired, thekeyboard tray 70 can be attached tolower platform 20, and items can be placed on it, such as a keyboard. According to embodiments,tray 70 can be located at an adjustable distance from thelower platform 20.
Referring to an alternative embodiment shown inFigure 14 , thekeyboard tray 70A can be attached to the bottom side of theupper platform 10. For example, ajoint component 72A can connect thetray portion 71A to the underside of thelower platform 10. When in use,keyboard tray 70A may move up and down withupper platform 10, thereby making it more convenient to access items placed onkeyboard tray 70, such as a keyboard.
Referring toFigure 15 , themain pivot arm 31 and/orsecondary pivot arm 32 can be cladded with aprotector 80. According to an embodiment, theprotector 80 is made with EVA foam (ethylene - vinyl acetate copolymer), however other materials are possible.Protector 80 can help prevent jammed fingers due to an operator reaching between pivot arm sets 30 and upper mountingbrackets 21.
Referring toFigures 16 and17 , embodiments of the adjustable desk platform not according to the invention can include legs that support the adjustable desk platform above the ground. For example, the adjustable desk platform can include fourlegs 90 extending from its comers, as shown, however, more or less than four legs are possible. Thelegs 90 can be fixed in length, or alternatively, can be adjustable in length using structures known in the art. Thelegs 90 can allow the adjustable desk platform to be self-supported above the ground. Except for the provision of legs and the related structures, embodiments of the adjustable desk platform shown inFigures 16 and17 can be substantially the same as described in connection withFigures 1-15 . - Referring to
Figure 17 , the adjustable desk platform can include aframe member 91 that attaches, for example, to the upper mountingbrackets 21, lower platform (not shown), or other part of the adjustable desk platform. For example, fasteners such as bolts or rivets, welding, bonding, or other attachment techniques can be used. Thelegs 90 can in turn be attached to theframe member 91, for example, using fasteners such as bolts or rivets, welding, bonding, or other attachment techniques. As shown inFigure 17 , an embodiment can includeend caps 92 that extend into open ends of theframe member 91, however, other configurations are possible. Referring back toFigure 16 , embodiments can include acover portion 93 that extends over and conceals all or a portion of theframe member 91, thereby improving the safety and/or appearance of the adjustable desk platform. Although not shown, lateral supports can extend between one more pairs of thelegs 90. - Referring to
Figures 18-21 , another embodiment of the adjustable desk platform is shown. The embodiment ofFigures 18-21 is substantially the same as shown and described in connection withFigures 1-15 . For example, the adjustable desk platform ofFigures 18-21 can include the same or similar pivot arm sets 30, locking set(s) 40, biasing mechanism(s) 50, reinforcement member(s) 60, counterweight, legs, and/or other features of previously-described embodiments. Accordingly, only additions or differences from previous embodiments are described below.
Generally similar to the embodiment ofFigure 14 , the adjustable desk platform ofFigures 18-21 can include akeyboard tray 70A suspended below theupper platform 10. Thekeyboard tray 70A can be adapted to support a computer keyboard, mouse, tablet computer, or other device. For example, thekeyboard tray 70A can be substantially planar, and can have a size equal to, or greater than, a conventional computer keyboard. According to an embodiment, the surface area of thekeyboard tray 70A is between about one half and about one quarter of the surface area of the upper platform. According to an embodiment, the surface area of thekeyboard tray 70A is about one third of the surface area of theupper platform 10. In order to provide sufficient space for thekeyboard tray 70A, according to embodiments, the pivot arm sets 30 can be lengthened as compared to embodiments without the keyboard tray, for example, to increase distance between theupper platform 10 andlower platform 20. For example, the pivot arms sets 30 may be increased lengthwise by between about 2" (5.08 cm) and about 5" (12.7 cm) as compared to embodiments without the tray, more specifically, by about 3" (7.62 cm) to about 4" (10.16 cm). As best seen inFigures 18 and19 , thekeyboard tray 70A can be generally "T"-shaped, in that it can define a relativelynarrow portion 100 joined to a relativelywide portion 102 to define a "T" shape. Thenarrow portion 100 andwide portion 102 are shown separated by an imaginary dashed line inFigure 18 for illustration purposes only. The edge of theupper platform 10 adjacent thekeyboard tray 70A can also define arecess 104, such as a generally "U" shaped recess. The width of therecess 104 can be the same or similar to the width of thenarrow portion 100 of thekeyboard tray 70A. As
a result, thenarrow portion 100 of thekeyboard tray 70A can be positioned generally in registry with therecess 104, for example, for ergonomic reasons. - Referring to
Figures 18 and21 , first andsecond support members keyboard tray 70A to theupper platform 10. According to embodiments, the first andsecond support members U-shaped recess 104. Additionally or alternatively, the first andsecond support members narrow portion 100 of the T-shapedkeyboard tray 70A. According to this embodiment, thenarrow portion 100 of thekeyboard tray 70A can fit the keyboard, and thewide portion 102 of thekeyboard tray 70A can provide additional support for the user's hands or wrists, however, other uses are possible. One of ordinary skill in the art will understand based on this disclosure that theupper platform 10 andkeyboard tray 70A are not limited to the specific shapes and appearances shown inFigures 18-21 . - Still referring to
