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 system includes a first vehicle component and a second vehicle component. The first vehicle component includes a first panel, a T-shaped projection protruding from a mating surface of the first panel, and a locking projection protruding from the mating surface of the first panel. The second vehicle component includes a second panel and a pair of ramped ribs projecting from a non-mating surface of the second panel. The second panel defines a slot that extends through the non-mating surface thereof. The slot includes a first portion having a first width and a second portion having a second width that is less than the first width. The ramped ribs are disposed on opposite sides of the second portion of the slot. The first vehicle component is configured to be fastened to the second vehicle component and located relative to the second vehicle component.

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.

A lock and pin for the structural and fluid tight repair of cracks not amenable to high temperature repairs or synthetic material patches. Fluid tight pins and locks seal the crack while one or more locks prevent the crack from growing. These repairs need to endure the remaining life cycle of the machinery part while withstanding all the strain, pressure, heat and expansion and contraction of the part before the crack(s) were formed. Often these cracks evolved due to engineering design flaws that will require even greater strength from these areas than when new.

An external screw member includes a parallel screw portion and a tapered screw portion provided on a side further toward a tip end than the parallel screw portion, and a plurality of sets of step portion and a transition screw thread portion are provided on at least one of the parallel screw portion and the tapered screw portion, the step portion having a reduced thread height in a radial direction and the transition screw thread portion gradually increasing in diameter from the step portion in an anti-driving rotation direction so as to reach a thread height of a normal screw thread portion. A top portion of the transition screw thread portion is positioned at an offset toward a pressure side relative to a position of a regular screw pitch in a minimum diameter portion of the step portion, and transitions to the regular screw pitch in the anti-driving rotation direction.

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.

A system includes a first vehicle component and a second vehicle component. The first vehicle component includes a first panel, a T-shaped projection protruding from a mating surface of the first panel, and a locking projection protruding from the mating surface of the first panel. The second vehicle component includes a second panel and a pair of ramped ribs projecting from a non-mating surface of the second panel. The second panel defines a slot that extends through the non-mating surface thereof. The slot includes a first portion having a first width and a second portion having a second width that is less than the first width. The ramped ribs are disposed on opposite sides of the second portion of the slot. The first vehicle component is configured to be fastened to the second vehicle component and located relative to the second vehicle component.

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.
