The invention relates to a method for forming an elongate cut-out (2), which has a varying transverse dimension in the longitudinal direction, in a workpiece (1), which is preferably composed of wood, wood materials, plastic, or the like at least in some segments, wherein the method comprises plunging a machining device into the workpiece (I), which machining device has an adjustable machining diameter; moving the machining device and the workpiece in relation to each other (II); adjusting the machining diameter of the machining device (III); and removing the machining device from the workpiece (IV).

Modular interlocking display systems including frames constructed from a plurality of modular frame elements. The modular frame elements each include a perimeter side equipped with a locking channel and interlocking mechanisms that allow frames to be joined together without the need of tools. Frames constructed from the modular frame elements include one or more display sides that are orthogonal from the perimeter sides and equipped to receive and hold silicone-edged display material flush to the display side. In some examples, display systems includes additional corner frame elements that allow frames to be secured at right angles, allowing display systems accommodate complex configurations. In some further examples, display systems include adjustable angle elements to allow display systems to position frame walls at arbitrary angles. In still further examples, display systems include adapter elements to allow display systems to integrate with third-party display systems.

A splicing metal plate has an elongated first connecting plate and an elongated second connecting plate, the edge of the first connecting plate is extended downwardly vertically with an accommodating portion with an opening, the edge of the second connecting plate extends downward vertically with an embedded portion, the accommodating portion and the embedded portion contact each other, the embedded portion is inserted into the accommodating portion; further comprising a front end cover and a rear end cover, the front end cover is connected to the front end of the first connecting plate and the second connecting plate, the rear end cover is connected to the rear end of the first connecting plate and the second connecting plate, the front end cover, the rear end cover, the first connecting plate and the second connecting plate surrounds and defines a groove structure with the bottom portion opening.

Disclosed is a connector that may include a first member and a second member. The first member may have a first fastening member and a first cavity, the second member may have a second fastening member and a second cavity, and the second fastening member may be engaged with the first fastening member. The insert may further include an insert in the first and second cavities.

A furniture assembly and/or a mechanical coupling system for coupling furniture parts together to form an assembled article of furniture. The furniture assembly may include first and second furniture parts, each of which includes a board or other structural member and a coupler. The first furniture part may include a male coupler attached to the board and the second furniture part may include a female coupler attached to the board. The male and female couplers may be coupled together to thereby couple the first and second furniture parts together to form the assembled article of furniture. The male and female couplers may include engagement features that facilitate the coupling of the furniture parts together and to prevent them from becoming detached during normal use of the assembled article of furniture.

A wall fastener system includes a structure-engaging insert configured to be secured to a structure. The structure-engaging insert includes a base plate and a protruding threaded connector extending outwardly from the base plate. The wall fastener system further includes a rail-engaging insert including a top plate and a protruding threaded connector extending from the top plate toward the structure. The protruding threaded connector of the rail-engaging insert is threadedly connected to the protruding threaded connector of the structure-engaging insert to selectively vary a spacing between the base plate and the top plate of the rail-engaging insert.
