  • Patent number: 11930919
    Abstract: A structure constructed using a blow-molding process comprising a tabletop, a lip, a pair of blow points, and a continuous tack-off. The tabletop includes an upper surface, a lower surface, and a hollow interior portion disposed between the upper and lower surfaces. The lip extends downwardly relative to the lower surface. The lip includes an outer and an inner surface. The blow points are configured to receive a blow pin. The blow points include a first portion connected to the lower surface, a second portion connected to the inner surface, and a hollow interior portion in fluid communication with the hollow interior portion. The continuous tack-off is disposed between the tabletop and the lip and extends between the blow points. The continuous tack-off prevents fluid flow between the tabletop and the lip along the section of the lip.

  • Publication number: 20240008639
    Abstract: A structure, such as a tabletop, may be constructed from blow-molded plastic. The tabletop may include an upper surface, a lower surface, and a hollow interior portion disposed between the upper surface and the lower surface. A lip may extend downwardly relative to the lower surface of the tabletop, and the lip including an outer surface and an inner surface. One or more supports may be disposed in the inner surface of the lip, and one or more joints may be disposed in the inner surface of the lip. A joint may be disposed between adjacent supports, and a distal portion of the lip may include a compression edge. A lower portion of the supports may contact the compression edge, and/or a lower portion of the joints may contact the compression edge.

  • Patent number: 11160366
    Abstract: An embodiment includes a leg height adjustment mechanism that includes a first and second latch arms, a first and second retractors, and an activator. The latch arms each include an engagement structure. The retractors each include a sloped surface and a receiving structure. The receiving structure is engaged with one of the engagement structures of the first or the second latch arms. The first latch arm extends in a first lateral direction and the second latch arm extends a second lateral direction. The second retractor is separated from the first retractor in a second lateral direction that is opposite the first lateral direction. The activator includes angled lower surfaces that are positioned outwardly relative to the sloped surfaces.
