A blow-molded plastic structure, such as a tabletop, may include an undercut. For example, the tabletop may include a frame receiving portion and a frame connecting structure with an undercut may be disposed in the frame receiving portion. A portion of the frame may contact or engage the frame connecting structure, such as the undercut, when the frame is connected to the tabletop. In an exemplary embodiment, a first side of the frame receiving portion may include a first frame connecting portion with an undercut and a second side of the frame receiving portion may include a second frame connecting portion with an undercut. The first frame connecting portion with an undercut may be disposed on an opposing surface from the second frame connecting portion with an undercut.

A plastic molded lip structure may extend along a perimeter of a planar element and may include an outer wall, an inner wall, structural portions, and protruded features. The outer wall may extend in a normal direction from the planar element. The inner wall may be disposed in an inward direction relative to the outer wall. The structural portions may be disposed along structural sections of the perimeter and may include first portions of the inner wall and of the outer wall. The first portions may be disposed parallel to the inner wall and separated from the first portions by a first distance along the structural sections. The protruded features may be interposed between two structural portions and an inner wall may be separated from second portions of the outer wall by a second distance that is greater than the first distance.

A structure, such as a tabletop, may be constructed from plastic, such as blow-molded. 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. A plurality of supports may be disposed in the inner surface of the lip, and a plurality of joints may be disposed in the inner surface of the lip. A joint may be disposed between adjacent supports. 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.

A method of producing an in-situ molded concrete object includes positioning a form on a substrate. The form can include a leg portion, a face portion, and a frangible portion. The frangible portion can connect the leg portion to the face portion. The method includes coupling the leg portion to the substrate to create a container open on at least one side. The method also includes pouring concrete into the container. The frangible portion can be fractured to separate the face portion from the leg portion.

A mobile color and style application device is disclosed. The device includes a base. The device further includes an adjustable tower coupled to the base. The adjustable tower including one or more tower locks configured to adjust a vertical height of the adjustable tower. The device further includes a plate coupled to the adjustable tower. The plate includes one or more tower locks configured to adjust a tilt angle of the plate. The device further includes one or more platforms. The one or more platforms are configured to couple to a portion of the plate via a quick-connect coupling mechanism. The one or more platforms include one or more cut-outs. The one or more cut-outs are configured to conform to a portion of at least one of a neck or a head of a user.

A table tennis apparatus including a table top made out of a fiberglass reinforced structural material (FRSM). The table tennis apparatus includes a pair of tables. Each table includes a table top having a three-layered composite panel made up of FRSM. The table top receives aluminum plates at its sides. Further, the table top receives mounting brackets at its bottom surface. The mounting brackets include male members that extend perpendicularly to the mounting brackets and fold over the mounting brackets. The table top rests at a height from the ground and allows its top surface to act as a playing surface for playing table tennis.

A hollow table top comprises a top plate and a bottom plate stacked together. The edge of the bottom surface of the table top is disposed with a metal frame. The edge of the top plate is disposed with a downwardly extending top plate side. The metal frame is disposed with a protruding portion in the horizontal direction extending out of the top plate side. The protruding portion protects the joint of the top plate and the bottom plate. The external edge of the table top has double-layer appearance.

A banquet table comprises a laminate tabletop with a high-pressure solid composite laminate of paper impregnated with resin. A hoop carries a perimeter of the tabletop and has a perimeter with a size and a shape substantially matching a size and a shape of a perimeter of the tabletop. Elongated runners carry an interior of the tabletop. Legs are coupled to the runners and extend to elevate the tabletop thereon. A polymer trim surrounds the perimeter of the hoop. The trim has a vertical height substantially the same as a vertical thickness of the hoop, with the tabletop extending above a height of the trim so that the tabletop has an exposed perimeter edge. The trim has a horizontal thickness extending laterally beyond the tabletop.

A plastic molded lip structure may extend along a perimeter of a planar element and may include an outer wall, an inner wall, structural portions, and protruded features. The outer wall may extend in a normal direction from the planar element. The inner wall may be disposed in an inward direction relative to the outer wall. The structural portions may be disposed along structural sections of the perimeter and may include first portions of the inner wall and of the outer wall. The first portions may be disposed parallel to the inner wall and separated from the first portions by a first distance along the structural sections. The protruded features may be interposed between two structural portions and an inner wall may be separated from second portions of the outer wall by a second distance that is greater than the first distance.
