Description
- This application claims the priority of Provisional Patent Application Ser. No. 61/626,963, filed on Oct. 6, 2011, and the priority of Provisional Patent Application Ser. No. 61/626,346 filed on Sep. 26, 2011.
- Not applicable.
- The present invention relates to portable and foldable workstations. The workstation is optionally useful as a chair or seating device, useful for outdoor activities. The present invention is in the technical field of furniture. More particularly, the present invention is in the technical field of workstations, foldable workstations, and all weather workstations. The workstation can optionally be reduced to a portable seating device by omitting a work-holding surface such as a table or tray portion.
- At the pace of technological change, there is a great demand for portable workstations and workstation devices. In particular, there is a need for portable workstations which can be folded so as to be readily portable, having a seat portion and a table portion for holding a book, electronic device, and papers, among other things. A number of workstation devices are known in the furniture and arts.
- Examples of prior art patents relating to portable devices having a seat can be found in U.S. Design Pat. No. Des. 338,345 issued to inventor Camp for a collapsible seat; U.S. Design Pat. No. Des. 474,041 issued to inventors Howard et al. for a portable folding chair; and U.S. Pat. No. 6,899,388 issued to inventor Enrique for a portable chair and cane with umbrella.
- It is a problem in the prior art to make workstation devices that would be portable and foldable, and easy to set up. Additionally, such workstation devices should be easy to collapse or fold, and should be easy to stow. Further, such workstation devices should have a work support tray, and should be stable in use, as well as lightweight.
- Outdoor folding chairs are also well known, particularly those with flexible fabric seats which are cot-like in operation. However, such outdoor folding chairs are not adapted to serve as portable workstations.
- None of the prior art devices are adapted to overcome the aforementioned deficiencies of the prior art. There is, therefore, a need in the prior art to provide a convenient, lightweight, portable workstation for outdoor use, having a support such as a shelf or table portion. Further, there is a need in the prior art to provide such a portable workstation which can be used outdoors and which therefore additionally includes a sheltering device or sheltering portion for providing shelter for the user from the elements found outdoors, including sun, snow, and rain.
- In view of the aforementioned deficiencies and needs in the prior art, and in addition to the foregoing, it is also a problem in the prior art to provide a lightweight, foldable, and easy to use workstation having an umbrella mounted on a movable support, to provide shelter from the elements while outdoors.
- It is a further problem in the art to provide a novel and useful construction of a foldable workstation device which overcomes the deficiencies of the prior art, including an improved construction, including improved pivot elements and ratchet joints for adjustable positioning of a sheltering device such as an umbrella.
- Further, it is a problem in the art to provide a convenient, lightweight, portable workstation which can be reduced to a chair by omission of a tray or table portion, while also having a sheltering device or portion for providing shelter for the user from the elements found outdoors, including sun, snow, and rain.
- From the foregoing, it is seen that it is a problem in the art to provide a device meeting the above requirements. According to the present invention, a device and process are provided which meets the aforementioned requirements and needs in the prior art. Specifically, the device according to the present invention provides a portable workstation having a seat and table or tray portion.
- The present invention relates to workstations, and particularly portable and foldable workstations. In addition, the workstation of the present invention is optionally useful as a cane, and has a cane head.
- Further, the workstation of the present invention can optionally be reduced to a portable seating device, specifically by omitting a work-holding surface such as a table or tray portion.
- In a preferred embodiment, the workstation includes a foldable seat and a foldable tray.
- The workstation of the present invention also includes an adjustable umbrella. The umbrella can be mounted to the cane head by a ratcheting mount so that it can be set at a number of different angles, so as to provide protection from the sun or rain. The umbrella can be folded easily when not in use.
