The present disclosure relates generally to a worktable, and more particularly, to a convertible, sturdy worktable that can be assembled and reassembled between an assembled use configuration and a storage configuration without the use of tools.
A convertible worktable is a worktable that can be disassembled and reassembled to provide a convenient working-surface that can be carried with the user to various locations. There are abundant examples of collapsible, convertible, foldable, and knock down worktables known in the art. In general, they tend to be quite specific in their purposes so that they may, for example, be limited in size for portability, or not require a great deal of stability or they may, as in the case of some knock down tables, be rather complicated with many parts and are intended to be assembled and left that way once they reach their destinations, and are not intended to be knocked down and reassembled on a regular basis.
Conventional solutions include a multi-purpose, convertible table, which can be used as a desk or a worktable, but it was not engineered to be completely dismantled or to be very sturdy for heavy use as it lacks support for the legs at the bottom. Also, there is a whole genre of worktables, or workbenches that are based on the sawhorse theme. It is evident that these types of worktables are not intended to replace the more rugged permanent, heavy-duty types of worktables, even though their usefulness and portability is evident.
Other examples of worktables which are referred to as knockdown worktables may have legs and/or tops or other parts that can be removed for shipping and assembly when they reach their destination, but after being reassembled at their destination, they are intended to remain in the assembled configuration permanently.
Therefore, there still exists a need for a convertible sturdy worktable that can be conveniently switched into an assembled use configuration and a compact storable configuration.
