This invention relates to ergonomic workplace environments, and more particularly to an adjustable desktop platform.
Sitting for long periods of time during the work day is 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.
A primary advantage of the present invention is to provide an adjustable desktop platform that can transition between a lower operating position and an upper operating position quickly, easily and simply.
A related advantage of the present invention is to provide an adjustable desktop platform that can transition between a lower operating position and a variety of higher positions.
Another advantage of the present invention is to provide an adjustable desktop platform that can convert existing desktop workspaces to height-adjustable workspaces.
In accordance with a preferred embodiment of the present invention, an adjustable desktop workspace comprises a base having a lower platform; an upper platform; two pivoting arms mounted between the base and the upper platform, each pivoting arm further comprised of a front and rear bracket; and a locking lever on each arm for fixedly engaging the platform in an upright position.
In accordance with another preferred embodiment of the present invention, an adjustable desktop workspace comprises an upper and lower platform hingedly connected by a first and second arm assembly; the first and second assembly comprised of a front and rear member; the members each having a first end and a second end, wherein said first end is connected to the base, and wherein the second end is connected to said platform; the front member is operably engaged to the rear member by a biasing mechanism; and a lever for locking engagement of the first and second arm assembly in an upright position.
Other objects and advantages will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
The novel features believed to be characteristic of the invention are set forth in the appended claims and claims yet to be filed. However, the invention itself, as well as a preferred mode of use and further objectives and advantages thereof, will best be understood by reference to the following detailed description when read in conjunction with the accompanying Figures wherein:
Detailed description of the preferred embodiment is provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Various aspects of the invention may be inverted, or changed in reference to specific part shape and detail, part location, or part composition. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
This specification outlines the development of an ergonomic work environment to allow a user to work while sitting or standing, and to transition between the two positions easily, quickly and simply.
This invention uses an adjustable desktop platform along with a system of spring aided pivoting arms and a multi-positional, adjustable, locking mechanism to raise and lower the desktop platform to provide a work space at a level useable for someone in a sitting position, and transition to provide a work space useable for someone in a standing position. The invention includes counterweights, covers and supports for added safety.
Turning first to
In the lowered position, pivoting brackets 31 and 32 are in a generally horizontal position and desktop platform 25 is over base platform 25, whereas in the fully upright position, desktop platform 25 is raised with pivoting brackets 31 and 32 in the generally vertical position. In the fully upright position, desktop platform 25 is also moved forward closer to the user, relative to base platform 15. Because desktop platform 25 is designed to be used in a workspace environment, and would likely have computer equipment such as screen, keyboard and mouse thereon, the added forward weight is counterbalanced by counterweight 35 shown towards the far end of base platform 15. As will be appreciated, the specific weight of counterweight 35 can be modified to the particular environment design and may depend on the weight of the desktop, the length of the pivoting arms and the shape of the desktop platform, among other things.
As is shown in
Turning next to
Springs 34 are also included to assist the user in countering the weight of the desktop platform 25 and any material thereon, such as a computer, screen, keyboard and mouse, to allow for smooth, easy raising and lowering of the desktop platform. Springs 34 are shown in
For additional security and stability, there is also included a locking mechanism 50, which also secures desktop platform 25 at a variety of distances from base platform 15. This feature is accomplished by the series of holes 51 in each of forward pivoting brackets 31. The series of holes 51 interacts with the pins and brackets 55 as shown in detail in
Forward lateral stabilizing bar 72 and rear lateral stabilizing bar 75 or supports are also shown in
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the currently or later appended claims.
