    Abstract: Apparatus for adjusting the longitudinal and angular position of a work surface support leg. The leg passes through a channel in a cap held via a spring and pin to a base affixed to the work surface. The leg's angular position is adjusted by rotating the cap, which moves a tooth through a series of mating depressions. The longitudinal position is adjusted by moving the leg which has a series of notches that mate with a locking tooth in the cap. A knob interfaces with the cap via a rotary cam having high and low steps and a matching cam rider. The low step allows separation between the cap and base and the high step locks the cap to the base, thereby locking in the adjustment setting for the leg.

  • Publication number: 20030106474
    Abstract: A collapsible table has a table top, such as may be formed by blow molding, with a substantially planar top surface and a bottom surface opposite the top surface. Formed into the bottom surface of the table top are opposing first and second channels. Disposed within the first channel is a first pivot bar, and disposed within the second channel is a second pivot bar. The table includes opposing first and second frame members secured to the bottom surface of the table top. Disposed between and pivotally attached to the first and second frame members are opposing first and second leg assemblies which are movable between a use position and a storage position. To maintain the first leg assembly in the use position, the table has a first support assembly including a first brace structure and a first support bar. The first brace structure has a first central pivotal attachment point, and one or more first distal pivotal attachment points attached to the first leg assembly.

  • Patent number: 6374756
    Abstract: A folding table (2) of robust construction having a reinforced picture-frame edge and underside elongate chassis members (24, 26) running along the length thereof, the chassis member (26) pivotally supporting two pairs of legs (6) and opposed track elements (40, 46) associated with each pair of legs. The track elements (40, 46) accommodate followers (50) attached to opposite ends (52, 53) of a connecting element (52) to which are fixedly secured legs (56, 58) of a support frame (54), legs (56, 58) of which pivotally connect the connecting element (52) to the legs (6) so that movement of the followers (50) in the track elements causes movement of the pairs of legs (6) between a first inoperative position and a second operative position. Latching members (70) are provided to lock each pair of legs (6) in one or other of their inoperative and operative positions and damper members (90, 140) are provided on each leg (32, 36) to prevent rapid movement of legs (32, 36) between said positions.

  • Patent number: 6353530
    Abstract: A method for supporting a base of a laptop computer on a user's lap. The base may have a lower surface with two concave depressions that extend from a forward edge to a rear edge of the base. The depressions are spaced apart from one another and configured to receive a user's legs to support the weight of the laptop computer. In one embodiment, the depressions have roughness elements or a skid-resistant material. In another embodiment, support members extending outwardly from the base provide extra support for the base and/or further restrict motion of the base relative to the user's legs.

  • Patent number: 5983807
    Abstract: A lightweight, high strength folding table having a top assembly which includes a novel high strength, plastic reinforcing core. Pivotally connected to the top assembly are supporting legs. Interconnecting the supporting legs with the top assembly are novel folding leg mechanisms which include top assembly engaging links and leg engaging links pivotally connected both to the top assembly engaging links and also to the supporting legs. A locking rod extends between the top assembly engaging links, the end portion of which is slidably received within a slot formed in each of the leg engaging links. When the rod resides within the locking portion of the slot, the top assembly engaging links and the leg engaging links are locked against relative pivotal movement. However, when the locking rod is lifted slightly, the rod ends move into the channel portion of the slot permitting free pivotal movement of the cooperating links.

  • Patent number: 5974982
    Abstract: A fitting for a table leg of a folding table which can be folded in when the table is not in use, wherein the table leg is pivotally mounted in a bearing component attached underneath the table plate. In the position of use of the table, the table leg can be locked. A drop lever is pivotally mounted in the bearing component. When the table leg is folded out into the position of use of the table, the drop lever automatically as a result of gravity locks the table leg against a stop serving as an abutment and automatically unlocks the table leg when the table is placed in a stacking position.
