Abstract: A system of fasteners and connectors that can be used as part of fashion items such as jewelry, leather goods and garments is provided. One or more fasteners can be used interchangeably with a range of connectors to accommodate various kinds of decorative and functional applications.

Abstract: Embodiments herein relate to the general art of connector links, and to the particular field of coupling links for coupling to one or more chain links. Particular embodiments include coupling links having a body with a central portion that has an aperture passing therethrough, a closed first end that is integral, and a second end that has an opening, and a retaining member in the form of a removable, deformable, or pivotable member that may selectively provide a closure to the opening. Other embodiments include retaining members on both ends of the coupling link.

Abstract: A tool-less chain coupling link has first and second body members releasably joined together. A first hinge pin is movably positioned within corresponding openings in the first and second body members. A first hinge pin keeper member is pivotally attached to the first body member and movably attached to the first hinge pin. A second hinge pin is movably positioned within other corresponding openings in the first and second body members. A second hinge pin keeper member is pivotally attached to the second body member and movably attached to the second hinge pin. The first and second hinge pin keeper members can be pivoted in a first direction to withdraw the first and second hinge pins, respectively, a sufficient distance to allow the first and second body members to be released from each other.

Abstract: A link for a chain, which is used in a linear actuator, comprises a base member and a plate pivotably mounted on the base member. An arm extends from the plate. A first connecting means is disposed on a distal end of the arm to connect the link with a first adjacent link. The plate has a protrusion for releasably engaging a second adjacent link. A second connecting means is disposed on the base member to connect the link with the second adjacent link.

Abstract: In a one-piece fastener, particularly for jewelry, which consists of two fastening members which are mounted at their one end for pivoting in a common axis of rotation and can be detachably connected at their other ends, one fastening member is constructed in the form of an inherently resilient double hook (2) with hook openings (8, 10) directed oppositely at each side of the tension axis (24) and the other fastening member is constructed in the form of a hinged locking means (1), the double hook being articulated on the hinged locking means (1) by one hook end being able to be frictionally secured in position on the hinged locking means (1) by its other end, through a detent (5) and a counter detent (7). Double hook (2) and hinged locking means (1) are pivotable through 360 degrees, crossing over and passing the detent, for the opening and closing of the fastener and are so constructed that a pivotal movement in one direction opens one hook opening (9) and closes the other (10) and vice versa.

Abstract: This invention relates to shackles.In more detail a shackle comprises a body component and a latch component wherein the latch component includes a latch arm hinged to the body component to form a closed loop therewith when latched, the latch arm having that end thereof remote from the hinge shaped for engagement with the body and to restrain opening from a latched position, a plunger housed within the body and movable against a biassing force between a first position in which the plunger extends into the latch arm to hold the latch arm in a latched position and a second position in which the plunger is withdrawn to permit opening of the latch arm, and wherein the body component includes a bore which communicates with an enlarged space, the bore serving, in use, to receive a stopper knot which prevents removal of the rope through the bore.

Abstract: In the depicted embodiment, the jib shackle comprises a two-section body having converging arms extending therefrom. The sections of the body are relatively rotatable, about the axis of the body, to move the converging limbs into and out of proximity with each other. When the limbs are put into proximity, they define a closed loop with the body, and when moved out of proximity, open the loop. Ends of the body are apertured to receive therethrough a line (rope, hawser, etc.) which may be knotted, within the loop, to prevent its withdrawal from the shackle. Ends of the limbs which are remote from the body have complementary configurations which cause such ends mutually to nest with each other, upon being closed upon each other, to define the surfaces of the loop with substantially no discontinuities or abrupt edges. The novel shackle is formed of rigid plastic, hence on shipboard use it will not mar or otherwise abuse wooden or fiberglass boat surfaces.

Abstract: A manipulatable structure that contains a series of linked units. Each unit contains a plurality of rhombic-shaped panels that are hinged along their oblique edges to create a collapsible enclosure that can be used to create two dimensional patterns when the panels are folded into one of two available common planes or any number of three dimensional structures when positioned between the two common planes. Each unit, in turn, is hinged to an adjacent unit along abutting oblique corners to create a chain that can be symmetrically formed by linking the units in a repeating linear pattern or asymmetrically formed by linking the units in a random fashion.

Abstract: A locking device for bracelets and necklaces having two ends, each provided with a chain link, includes a first plate and a second plate which are pivotably coupled together for movement about a common pivot axis between an opening and locking position. The plates each have an aperture formed therethrough aligned with the pivot axis through which one of the chain links may extend and the first plate has a hook-like end portion for receiving the other of the chain links. The second plate has an arcuate slot formed therein running in a concentric manner with respect to the pivot axis which defines an arched portion on an end portion of the second plate disposed distal to the pivot axis relative to another end portion thereof. The arched portion also runs concentrically with respect to the pivot axis and, in the locking position, is received through the other chain link received in the hook-like end portion of the first plate.

Abstract: An improved hoisting hook or becket including an upper body member having an eye in the upper portion for receiving a cable, hook or the like for lifting the becket and any load attached to it, the body having spaced apart openings near the bottom edge, a lower U-shaped shank member having ends which are in a common plane and having openings near each of the ends, the openings in the shank and body being substantially equidistant and a pair of links each having parallel side plates and parallel horizontal upper and lower pins, the lower pins of each link being received in the openings in the shank and the upper pin of one of the hooks being received in the first opening in the body so that the shank is pivotal relative to the body, the second opening in the body having open communication through the top of the body member and providing means so that the upper pin of the second link can be slidably moved into and out of the second opening, the dimensions of the body, shank, hook and links being arranged such t
