1. Field of the Invention
In general, the present invention relates to the structure of collapsible tables. More particularly, the present invention relates to tables, where both the tabletop and the table legs are collapsible to form a compact folded table.
2. Prior Art Description
Many people like to carry a table to the beach or to a picnic. However, although many folding tables exist, few are light enough and small enough to justify the effort it takes to carry them long distances.
Many folding tables, such as card tables and banquet tables, have legs that fold for convenience of storage. These tables, although foldable, are heavy and are not intended to be carried by a single person across any significant distance. Lighter, smaller tables, such as food tray tables, do exist. However, many such folding tables only have legs that fold. The tops of the tables remain rigid. As a result, although the tables are lightweight, they are very bulky and cumbersome to carry.
A few prior art folding table designs do exist that are both lightweight for transport and have a folding tabletop. Of these prior art folding tables, most have tabletops that fold directly in half. Such prior art folding tables are exemplified by U.S. Pat. No. 3,074,770 to Sqob, entitled Camping Table.
Tables with tabletops that fold in half typically are manufactured with a handle at one end of the tabletop. As such, the folded tabletop dangles under the handle when the handle is held in a person's hand. Where this provides a means to carry the folding table, it is very difficult to carry such tables by holding the handle with an extended arm. If carried in such a manner, the half-folded table could easily contact the ground as it is being carried. This is especially true if the person carrying the folded table has a small stature. Consequently, the handles provided on such prior art tables are usually used only to lift and manipulate such tables. The handles serve little purpose in transporting the tables while walking. The folded table remains bulky and cumbersome to carry.
A need therefore exists for a table that is very lightweight and has both a tabletop and table legs that collapse into configurations that are far less than half their normal size. In this manner, the table can become small enough to comfortably transport by simply lifting and carrying the collapsed table with one hand. This need is met by the present invention as described and claimed below.
The present invention is a folding table assembly. The folding table has both a tabletop and legs that fold into smaller sizes. The tabletop has a main panel, a first side flap panel, and a second side flap panel. The first side flap panel and the second side flap panel are joined to the main panel with hinge connections. The hinge connections enable the first side flap panel and the second side flap panel to rotate from open positions that are coplanar with the main panel to folded positions that are under the main panel.
A plurality of folding legs are provided. The folding legs are coupled to the first side flap panel and the second side flap panel of the tabletop. The folding legs can move between extended positions, where the legs support the tabletop, and retracted positions, where the legs are folded flush against the first side flap panel and said second side flap panel. In this manner, the two side flap panels of the tabletop can fold under the main panel of the tabletop. The legs can fold flush against the side flap panels so that the legs are interposed between the main panel and the two side panels. This enables the table to fold into a very compact size that is easy to carry.
For a better understanding of the present invention, reference is made to the following description of an exemplary embodiment thereof, considered in conjunction with the accompanying drawings, in which:
Although the present invention folding table can be configured in many ways, only one exemplary embodiment of the folding table is illustrated. The embodiment selected sets forth the best mode contemplated for the invention. The illustrated embodiment, however, is merely exemplary and should not be considered a limitation when interpreting the scope of the appended claims.
Referring to
The two side flap panels 18, 19 interconnect with the main panel 16 using hinges 21. The hinges 21 enable the two side flap panels 18, 19 to rotate from an open position, where the side flap panels 18, 19 are coplanar with the wide main panel 16, to a closed position, where the side flap panels 18, 19 lay under the wide main panel 16. Each of the hinges 21 are made from two hinge projections 20, 22 that mechanically interconnect.
The wide main panel 16 has four corners 23, 24, 25, 26. Hinge projections 20 extend from the wide main panel 16 in each of the four corners 23, 24, 25, 26. The first side flap panel 18 has two inside corners 27, 28 that face the wide main panel 16. Likewise, the second side flap panel 19 has two inside corners 29, 30 that face the wide main panel 16. Hinge projections 22 extend from the side flap panels 18, 19 at the inwardly facing corners 27, 28, 29, 30. The main panel 16 and both the side flap panels 18, 19 are integrally molded with their plastic hinge protrusions 20, 22. The hinge protrusions 22 on the side flap panels 18, 19 mechanically interconnect with the hinge protrusions 20 on the wide main panel 16. This enables the side flap panels 18, 19 to fold between their open positions and folded positions.
As has been previously stated, when the side flap panels 18, 19 are in their open positions, the side flap panels 18, 19 are in the same plane as the main panel 16. The side flap panels 18, 19 and the main panel 16, therefore, present a single flat tabletop 12. The tabletop 12 can have any dimensions by varying the lengths and widths of the wide main panels 16 and the two side flap panels 18, 19. However, it is important that the length of the side flap panels 18, 19 be the same as the length of the wide main panel 16. Furthermore, it is important that the width of each of the side flap panels 18, 19 be equal to, or less than, half the width of the wide main panel 16.
The tabletop 12, when open, is supported by four separate leg assemblies 14. Each of the four leg assemblies 14 is comprised of two plastic parts. Those parts include an upper leg element 32 and a lower leg element 34. Both the upper leg element 32 and the lower leg element 34 are molded of plastic as separate parts. The upper leg element 32 and the lower leg element 34 are later joined to form a complete leg assembly 14. Each upper leg element 32 is molded with upper hinge projections 36 and lower hinge projections 38. The upper hinge projections 36 extend upwardly from the top corners of the upper leg element 32. Conversely, the lower hinge projections 38 extend downwardly from the lower corners of the upper leg element 32.
The lower leg element 34 has hinge pins 40 that extend laterally from the sides of the lower leg element 34 proximate its upper corners. The hinge pins 40 mechanically interconnect with the lower hinge projections 38 of the upper leg element 32. The result is a hinge connection between the upper leg element 32 and the lower leg element 34 that enables the lower leg element 34 to fold flush against the inside of the upper leg element 32. Furthermore, the hinge connection also enables the lower leg element 34 to linearly align with the upper leg element 32 to form a straight leg assembly 14.
Hinge pins 42 also extend from the long side edges of the side flap panels 18, 19. The upper hinge projections 36 of the upper leg elements 32 mechanically interconnect with the hinge pins 42. This forms a hinge connection between the side flap panels 18, 19 and the upper leg elements 32 of the leg assemblies 14.
Referring now to
A carry bag 46 is provided that is sized to receive the folded table assembly 10. The carry bag 34 has handle straps 48 that make the carrying of the table assembly 10 for long distances a comfortable endeavor. Since the entire table assembly 10 is made of molded plastic, the table assembly 10 is very lightweight. Furthermore, the table assembly 10 is capable of being repeatedly wet with ocean water or other moisture without concern of having metal parts corrode.
It will be understood that the embodiment of the present invention being illustrated is merely exemplary and that a person skilled in the art can make many variations to that embodiment. For example the length, width and height of the table assembly can be varied as desired. All such variations and alternate embodiments are intended to be included within the scope of the present invention.
This applications claims the priority of provisional patent application No. 61/485,780, entitled Lightweight Folding Table, filed May 13, 2011, the disclosure of which is incorporated by reference.
