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 lightweight beam structure includes a first and a second frame. The first frame includes an upper plate, two inner side plates downward bent and extended from two sides of the upper plate, two outer side plates upward bent and extended from two inner side plates respectively and two fixing plates bent and extended from two outer side plates respectively. Each outer side plate is formed outside each inner side plate. A groove is formed between each inner side plate and each outer side plate. The second frame is connected with the first frame and includes a top plate and two intermediate plates downward bent and extended from two sides of the top plate. Each intermediate plate is received in each groove. The top plate is formed over the upper plate. Therefore, the stability is maintained and the weight is reduced so that the material costs may be decreased.

Disclosed is an assembly-friendly table frame, which relates to the field of lift tables. The table frame includes an upright and a base stand mounted to the underside of the upright; one of the base stand or the upright is securely coupled with a connecting member, and the other thereof is provided with a locking bump; the connecting member includes an insert-fitting rail and a locking slot provided in the insert-fitting rail; the locking bump is sequentially inserted into the insert rail and slid to be snapped into the locking slot; the table frame further includes an ejector member configured to eject the locking bump out of the locking slot. Further disclosed is a table applying the table frame. An advantage of the present disclosure lies in enhancing convenience of assembly and disassembly between the upright and the base stand.

The disclosure is a beam structure for a leg stand of an electric table, which includes a first frame and a second frame. The first frame includes an inner bottom plate, an inner side plate and an inner embedding plate. The inner embedding plate is formed on outside of the inner side plate. The inner embedding plate includes an exposed section. The second frame is movably connected with the first frame. The second frame includes an outer bottom plate, an outer side plate and an outer connecting plate. The inner bottom plate is formed above the outer bottom plate. The inner side plate is formed on inside of the outer side plate. The inner embedding plate is correspondingly embedded in the outer connecting plate. The exposed section is exposed from the outer connecting plate.

A movable table assembly comprising a base portion and a table support each having angular connecting nub with an interior cavity to enable fastening inline with a support leg. The preferred assembly utilizes a base portion, a support leg, a table support, and a table. The base portion and table support being generally planar and having a first side and second side defined by an edge around a perimeter. The support leg coupled between the base portion and table support to generally provide a movable work surface, wherein the table and base portion are generally positioned parallel to a ground surface despite the angular connection.

The utility model relates to pieces of furniture, namely, to multifunctional tables that can be used both as a sports equipment for fitness classes and as a traditional coffee table. The fitness table contains a table top and legs. The outer surfaces of each of the legs are provided with grooves made with the possibility of placing a harness expander in them. The grooves of the adjacent legs are made mirror-symmetrically. The utility model allows you to expand the functionality of the device.

Panels are shown, which are provided with a mechanical locking system including a separate and flexible tongue allowing connection with a snap action. An outer edge part of the separate flexible tongue includes a guiding protrusion for disassembly of the panels and that is deformed during locking and/or unlocking.
