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 strip-shaped rib can comprise at least one longitudinally extending arm and one more ore transversely extending arms. In particular, the one or more spaced apart transversely extending arms can increase the contact surface of the strip-shaped rib and the strip-shaped groove. Moreover, the connected boards do not need connectors. In addition, the board coupling structure can have a wide range of applications with a particular use in connecting two adjacent boards of a box.

Hard panels formed from a wood-based material and having a decorative layer for floor coverings are provided, at least on two opposite edges, with coupling devices made in one piece with the panels wherein similar panels may be coupled together to form a floor covering, wherein these coupling devices provide for an interlocking in a direction perpendicular to the plane of coupled panels, as well as in a direction perpendicular to the edges concerned and parallel to the plane of coupled panels. These coupling devices are constituted of a tongue and a groove. The top side of the tongue has a protrusion that cooperates with a meshing recess located in the lower side of the upper lip of the groove of the coupling devices, and a portion extending generally parallel with the plane of the panel to form a contact surface cooperating with the lower side of the upper lip of the groove.

A fastener for coupling together parts with a curved surface has a male member and a female member. The male element has an overall I-shape with a head portion, neck portion and a body portion. The body portion is adapted to be coupled with one of the curved part. The head portion includes an ear on each side. A first surface on the male member is arcuate along the body, neck and head portions. The female member includes a pocket with a pair of deflectable projections. The projections extend from opposing walls toward one another. The projections engage the male member along the neck portion between the head portion and body portion to retain the male member with the female member.

The invention relates to a panel designed for mechanical connection with at least one further, identical panel by means of pivoting, with a tongue and groove profile (6, 8) for fastening the panels (2, 4) at the same height with respect to one another, comprising a groove profile (6) with a short groove cheek (14), a groove bottom (16) and a long groove cheek (18) on at least one side of the panel and a tongue profile (8) corresponding to the groove profile (6) on at least one side of the panel, wherein the long groove cheek (18) has a greater thickness (M) at its free end (20) than in the region under the free end of the short groove cheek (14), and wherein in the assembled state the tongue and groove each have upper bearing faces (24a, 24b), which are inclined with respect to the surface (10) of the panel (2, 4), and lower bearing faces (26a, 26b) which are rounded, and with locking means (28a, 28b) for fastening the panels (2, 4) in the same plane with respect to one another, comprising a locking face (28b) on the tongue and a locking face (28a) on the groove, wherein the locking faces (28a, b) on the groove and on the tongue are arranged between the surfaces (10, 12) of the panels (2, 4) in the region of the free end (20) of the long groove cheek (18). To make it possible for the panels to be assembled without deformation and jamming, and thereby avoiding damage during the laying operation, provision is made for the height H of the locking faces (28a, 28b) not to be more than 20% of the maximum height M of the long groove cheek (18).

A light-emitting display system has an alignment mechanism to align or angle light-emitting tiles of the display. A first tile connects to a second tile by joining a first clamp portion on the first tile with a second clamp portion on the second tile. In an implementation, the alignment mechanism includes a replaceable angle adjustment insert that is inserted into at least one of the clamp portions, such as the first clamp portion. When the first and second clamp portions are joined, a surface of the second clamp portion presses against the insert and a desired angle between the first and second tile is formed. The insert can have any angle so that any desired angle can be formed between the first and second tiles.

A fastening device (3) for detachably fastening a medical instrument (2A-2E) to a holding structure (1) includes two crossbeams (4A, 4B), two longitudinal beams (5A, 5B) with a claw (6) for extending behind a holding surface (1A) of the holding structure. A guide (7-9) is provided, by which the crossbeams (4A, 4B) are moved in the direction of the claws (6) of the longitudinal beams during a motion of the longitudinal beams (5A, 5B) in relation to one another. A clamping structure (12) is provided for moving the longitudinal beams (5A, 5B) in relation to one another.
