Aspects of the disclosure relate to mechanical designs and apparatus. Specifically, aspects of the disclosure relate to furniture dollies.
Furniture is used every day. At times, a single piece of furniture is used for multiple purposes. A single piece of furniture can be used in various locations at separate times. Therefore, furniture is transported from one location to another location. Due to the weight and size of furniture, transporting furniture often becomes difficult. A furniture dolly assists in transporting furniture. A furniture dolly is a platform on wheels that holds and transports furniture. The furniture is placed on the dolly. The dolly can be wheeled from one location to another location. Often, a furniture dolly can transport multiple pieces of furniture simultaneously.
Conventionally, furniture dollies are designed to carry furniture having specific form factors. Accordingly, there are different furniture dollies for different furniture items. A chair dolly is designed transfer chairs. A seminar table dolly is designed to transfer seminar tables. However, a single furniture dolly cannot transport multiple types of furniture items. Conventional furniture dollies cannot even transfer furniture items of the same type having different form factors. Conventional furniture dollies are not designed to transport furniture of ranging widths, lengths, heights or weights other than the furniture for which the dolly was designed.
Furthermore, typical doorways measure 32-inches in width. At times, 18-inch-wide tables are placed side-by-side on a dolly. As such, the width of the dolly holding the side-by-side 18-inch tables is not less than 36-inches. Such a table-holding dolly is wider than a typical 32-inch-wide doorway. As such, a 36-inch-wide dolly is difficult, if not practically impossible, use for transporting the two 18-inch-wide tables in a side-by-side arrangement through many doorways.
Therefore, it would be desirable to create an adjustable multiple-purpose (“multi-purpose”) furniture dolly. Such an adjustable multi-purpose furniture dolly may hold multiple types of furniture. Such an adjustable multi-purpose dolly may also hold multiple 18-inch-wide tables in an arrangement with a width of 32 inches or less.
An adjustable multi-purpose dolly is provided. The multi-purpose dolly may be adjusted to transport different size furniture. Different size furniture may include furniture of a plurality of ranging size lengths, widths, heights and/or weights.
The multi-purpose dolly may include adjustable angle supports. Adjustable angle supports may hold furniture on an angle. As such, adjustable angle supports may enable furniture to be transported on an angle, thereby allowing more furniture to be transported at the same time.
For example, the dolly may hold 18-inch-wide tables. The angle supports may hold the tables at an angle. The angle may reduce the width of the multi-purpose dolly. As such, two stacks of 18-inch-wide tables may fit through a 32-inch doorway.
In some embodiments, the multi-purpose dolly may include removable support bars. The removable support bars may provide support for furniture in transit. The removable support bars may support furniture less than a predetermined length or width.
Aspects of the disclosure relate to a multiple-purpose (“multi-purpose”) dolly. Methods, apparatus, and systems for a multi-purpose dolly and its usage and creation are provided.

Tables may include stage tables, seminar tables, square tables, rectangular tables or any other suitable tables. The lengths and widths of the tables may vary.
The dimensions, including the length, width and height of the furniture may vary. Furniture stored and/or transported on the multi-purpose dolly may have a length of 60-inches, 72-inches, 96-inches or any other suitable length. The dolly may be adjusted to fit the length of the furniture. Furniture, such as tables may be 18-inches-wide or any other suitable width.
