Definitions

  • the present invention generally relates to tables and, in particular, to a light-weight table that may be adjustable in height and may have legs that can be moved between a extended or use position and a collapsed or storage position.
  • Conventional tables often include table tops constructed from wood, particle board or metal. Table tops constructed from wood, particle board or metal, however, are often relatively heavy and this may make the table awkward or difficult to move. Conventional table tops constructed from wood or metal are also relatively expensive and the table tops must generally be treated or finished before use. For example, table tops constructed from wood must generally be sanded and painted, and metal table tops must be formed into the desired shape and painted. In addition, these relatively heavy table tops increase the cost of transportation, shipping, and storage of the tables.
  • table tops can be constructed from relatively thin, light-weight materials.
  • these light-weight table tops frequently require reinforcing members or other structural parts such as brackets, support members and the like to strengthen the table top.
  • These additional parts may increase the strength of the table top, but these additional parts also increase the weight of the table.
  • these additional parts increase manufacturing costs and require additional time to assemble the table.
  • these additional parts may have sharp edges that can injure the user's arms or legs.
  • Known tables may also allow the height of the table to be adjusted to suit the needs of a particular user. For example, the length of the table legs may be increased or decreased by a telescoping assembly.
  • the assembly is relatively heavy.
  • conventional tables may use other mechanisms to allow the height of the table to be adjusted, but these devices are often relatively complex and require additional parts, which generally increases the amount of time required to manufacture the table and the costs to assemble the table.
  • These complex designs may also result in .tables that are relatively difficult for the consumer to use and these tables may require a substantial amount of time in order for the height of the table to be adjusted.
  • Another type of known table is a traditional card table in which each leg is pivotally connected to the table top by a brace and each leg individually folds against the table top. It is known to attempt to reduce the inconvenience of individually folding each of the legs against the table top by coupling two of the legs together by a long connecting rod. This may increase the stability of the table top and enable the user to simultaneously fold two legs into the collapsed position.
  • the long connecting rods may increase the cost of the table, reduce space under the table top, and the rods often easily break or become disconnected.
  • Conventional tables may also detachably connect the legs to the table top to allow the user to more easily collapse, move and store the table.
  • the detachable legs often create a table that is not sturdy or stable. Additionally, moving a table with this type of attachment when the legs are still attached is often difficult because the legs may undesirably detach.
  • These known types of table may include an attachment that mechanically secures the leg to the table top. These mechanical attachments, such as plastic or metal clips or brackets, often break or are otherwise damaged. Further, attachment of these devices to the table top may structurally weaken the table top, which may allow the table to unexpectedly fail.
  • attaching multiple separate attachment mechanisms to the table top by fasteners such as screws or bolts may undesirably weaken the table top.
  • Many conventional tables include four legs in order to support the table top above a surface such as the floor. The four separate legs, however, increase the weight of the table. In additional, the four legs require four separate attachment mechanisms to attach the legs to the table top, which increases the cost and complexity of the table. The four separate attachment mechanisms may also undesirably increase the weight of the table and require multiple mechanical fasteners such as screws and bolts to connect the attachment mechanisms to the table top.
  • One aspect of the present invention is a relatively small-sized table that is designed for use by a single person.
  • This type of table that is intended for use by an individual is referred to as a personal table, but it will be appreciated that more than one person could use the table if desired.

Surprisingly, the depressions 76 may increase the structural integrity of the structure despite forming disruptions in the continuity of bottom portion 18 of the table top 12, and less plastic can be used to make the structure even though the plurality of depressions are formed in the structure. The costs of manufacturing and transportation may be decreased because thinner plastic walls may be used to construct the table top 12, which may create a lighter weight table 10.
  • blow-molded structures when blow-molded structures are formed, a certain amount of time must elapse before the structure can be removed from the mold. Blow- molded structures with thicker walls require a longer cooling time than structures with thinner walls. The depressions 76, however, may allow table tops with thinner plastic walls to be constructed and that reduces the cooling time before the structure can be removed from the mold. Significantly, a reduced cycle time may increase the efficiency of manufacturing process. In addition, because less plastic is required, the cost of the table 10 may be reduced.
