Abstract: A magnetic closure with mutual interlock for bags, knapsacks, items of clothing and the like, comprising a female element and a male element with regions for accommodating magnetic elements for mutual coupling. A particularity consists in that there are provided, on the female element, guiding means for coupling to the male element and, on the male element, mechanical engagement elements which are adapted to contrast the mutual sliding of the male element and the female element.

Abstract: A clip device includes a first board with a T-shaped connection plate extending from a first surface thereof. The T-shaped connection plate includes a first plate extending vertically from the first surface of the first board and a second plate is connected on a top edge of the first plate. A second board has a groove defined in a first surface thereof and two receiving spaces are defined in the groove. The second plate is engaged with one of the two receiving spaces of the groove. Two flaps of a box are received in two sides of the clip device.

Abstract: A fastener includes a male fastening member having a springy hook plate and a retaining block and a stop block, and a female fastening member having a hook hole and a retaining hole and a recessed bearing portion. The retaining block and the stop block are forced into engagement with the retaining hole and the recessed bearing portion when hooking the springy hook in the hook hole. Turning the male fastening member outwards from the female fastening member to disengage the retaining block from the retaining hole enables the male fastening member to be separated from the female fastening member.

Abstract: An apparatus for securing articles to a vehicle-mounted rack. The apparatus includes at least one flexible strap associated with the rack. The strap is positionable around an article supported by the rack. A clamping buckle is adapted to receive and clamp onto the strap. A protective housing is adapted to receive and at least partially cover the buckle to protect the article and the vehicle from damage. In one embodiment, the strap may be attached to the housing to prevent the housing from being separated from the strap. In another embodiment, the housing may include one or more apertures to allow a user to operate the buckle when it is covered by the housing.

Abstract: A new self-mating mechanical fastener is disclosed, which comprises a base sheet and a multiplicity of parallel, narrowly spaced, elastically deformable ribs projecting from the base sheet. The ribs comprise a stem portion attached to and substantially upright from the base sheet and at least one flange attached to each side of the stem portion and spaced from the base sheet. At least the outer portions of the flanges desirably project toward the base sheet. The cross-sectional profile formed by the ribs is substantially uniform over the length of the ribs, but in the direction transverse to the ribs has a regularly repeated deviation from the profile that would be formed by a full population of equally spaced, identical, undivided, symmetric ribs.

Abstract: An article (10), has a first article portion (12), a second article portion (14), and a fastener (36). The fastener secures the first article portion to the second article portion and includes at least one first fastener component (70), which is attached to the first portion of the article. A cooperating, second fastener component (72) is mechanically interengageable with the first fastener component (70) and is attached to the second portion of the article (14). The first fastener component (70) includes a plurality of engagement members (56) having a first quantity of engageable stalk members (94).
