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.
  • US 2013/0139736 A1 discloses an adjustable desktop workspace is disclosed having a base having a lower platform, an upper platform, and two pivoting arms mounted between the two. Each pivoting arm has a front and rear bracket. A locking lever on each arm fixedly engages the platform in an upright position at a variety of levels above the lower platform. There are also two stabilizing bars to limit side-to-side relative movement, and a biasing spring between the front and rear brackets to aide moving the upper platform.

  • Arc slot 211 can be selectively connected with the respective secondary pivot arm 32 on the other side of the respective upper mounting bracket 21.
  • Pivot point 54 can be located against the bottom side of booster spring 53,
  • Each biasing mechanism 50 can be located between the respective upper mounting bracket 21 and housing 23, thereby concealing the biasing mechanism 50.
  • reinforcement member 60 may extend between the left and right pivot arm sets 30.
  • reinforcement member may include a supporting rod 61 and a separate reinforcement 62, however, other single-member and multi-member embodiments are possible.
  • 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.

  • the keyboard tray 70 can be detachably connected with lower platform 20.
  • Keyboard tray 70 includes a tray portion 71 and one or more releasable joint component(s) 72.
  • two joint components 72 can be connected on opposed sides of tray portion 71.
  • the joint components 72 can be slidably mounted on the lower platform 20. Additionally or alternatively, the joint components 72 can be drilled in the housing 23 of lower platform 20.
