A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.

A retaining assembly to attach one or more mobile devices to a mobile object. The retaining assembly may include a mounting plate that attaches to the mobile object by way of a mounting bracket or scorecard clip-on. The mounting bracket provides dovetails for selecting engaging the mounting plate in different orientations. The mounting plate facilitates various magnetized components to removably attach to the mobile device. If the mobile device has a third-party extensible grip, a retaining ring may be employed to attach the mobile device or the extensible grip modified to one of the various magnetized components.

An improved joint is provided for modular furniture. The joint includes a dovetail shaped tab and a corresponding slot. The tab is held in the slot such that the tab is maintained in an elastically bent position while the item of modular furniture is in an assembled configuration. The tab and slot provides increased stiffness and rigidity to the piece of furniture while allowing the piece of furniture to be assembled without fasteners such as screws or nails.

An emblem assembly includes a body of a polymeric material. A polymeric material extending portion is homogeneously connected to the body. The extending portion has a dove-tail shaped connector outwardly and homogenously extending from the extending portion. The dove-tail shaped connector defines a V-shape having a first wing and a second wing. An attachment member includes a first recessed pocket receiving the first wing and a second recessed pocket receiving the second wing to frictionally couple the attachment member to the extending portion.

A drive train connector assembly includes a first connecting structure and a second connecting structure. The first connecting structure has an attachment protrusion with first and second edges. The first edge extends in a first direction. The second edge extends in a second direction. Both directions are perpendicular to the rotational axis. The first and second directions define a first acute angle therebetween. The second connecting structure defines recessed area. The attachment protrusion fits into the recessed area. The recessed area defines third and fourth edges. The third edge extends in a third direction and the fourth edge extends in a fourth direction. The third direction and the fourth direction define a second acute angle. With the attachment protrusion installed within the recessed area the first and third edges are parallel to one another and the second and fourth edges are parallel to one another.

Key threaded articles and systems that include key threads having a female lock and male key on a two-dimensional plane and in which the female lock envelops the male key when fully engaged and has a shape that creates lateral resistance to separation from the male key when the female lock fully engages the male key.

The present subject matter discloses a board coupling structure with a first board and a second board. The first board and the second board are respectively formed with strip-shaped ribs and strip-shaped grooves that can be interlocked with each other. The first board and the second board can only move relative to each other in the inserting direction. The strip-shaped rib has a constricted portion and a clamping portion. The advantage of the present subject matter is that the contact surface and biting degree of the connected boards are larger. The coupling structure is stable with improved waterproofing of the connection. Moreover, the boards do not need to be connected by connectors during assembling, which renders a fast and convenient assembly.

A bottle rack includes a panel that has a front surface and an opposing back surface, and support bars cantilevered from the panel and extending from the front surface. Each of the support bars has a linear bottle supporting portion that is positioned, and that is at an acute angle, relative to the front surface such that at least two of the support bars can support a bottle while forcing the bottle against the front surface. The rack may be a “label forward” rack. Additionally, the various joints, grooves, and slots used to join the support bars to the panel may also be used to join any the support bars and panels of any suitable bottle rack.

A mechanical connection interface for connecting and releasing optical components is disclosed. The mechanical connection interface includes a slide latch arrangement for securing an optical component such as a splice holder to a structure such as a tray.
