  • Patent number: 6195977
    Abstract: The watchband or jewelry bracelet with articulated links and flexible fittings comprises links (1, 2, 3, 4) articulated with each other. Each link comprises a lower part (6), side walls and upper shoulders (5) constituting a receptacle (7) in which a flexible fitting is to be mounted. At one end of each link, the side walls have a convex semicircular portion (11), and at the other end, they have a concave semicircular portion (10). At said other end, rings (8) having a thread (9) are mounted on the lower part (6) of the link and in the receptacle (7). The links are assembled together by screws (15, 16) cooperating with threads of the rings. The concave and convex semicircular portions are intended to cooperate with each other in this assembly position.

  • Patent number: 5592810
    Abstract: A stamped link and a method of forming the link. The link is a clevis link formed of a single piece of sheet metal and includes a generally planar main body portion, a curl portion proximate the rearward end of the link forming a first bearing surface defining a rearward pivot axis, longitudinal edge flange portions upstanding from the main body portion, side wall portions upstanding from the main body portion proximate the forward end of the link inboard of each edge flange portion and each having an upper edge generally at the level of the upper edge of the associated edge flange, a central ridge upstanding from the main body portion between the ends of the link and blending at its forward end in the side walls, and aligned apertures in each edge flange and its associated side wall proximate the forward end of the link forming a second bearing surface defining a forward pivot axis.

  • Patent number: 5533328
    Abstract: A link is formed by forming a bubble between the longitudinal side edges of the link extending from the forward end of the link to a location spaced from the rearward end of the link so as to form laterally spaced upwardly extending side walls proximate the forward end of the piece spaced inboard from the respective longitudinal side edges of the link, forming the rearward end of the link into a curl to form a first bearing surface defining the rearward pivot axis, bending the longitudinal side edges of the piece upwardly to form an edge flange positioned proximate the forward end of the link outboard of each side wall, removing the bubble proximate the forward end of the link while leaving the side walls intact so as to form the clevis configuration at the forward end of the link, and forming aligned holes in each edge flange and its associated side wall to form a second bearing surface defining the forward pivot axis.

  • Patent number: 5341634
    Abstract: An interlocking link chain for use in jewelry and other decorative items. The interlocking links can be assembled and disassembled by the wearer without special tools and without an unusual degree of dexterity. The wearer can assemble a chain of any length for use as a bracelet, a necklace, a belt, or other decorative items. Each link has a tab portion and a slot portion. Each link may also have a body portion which expresses an artistic or decorative motif. In some embodiments, the tab and the slot may be made an integral part of the decorative motif. The links are arranged in a linear chain so that the tab portion of each link interlocks with the slot portion of the adjacent link. The links are made in a generally planar configuration that lends itself to low cost manufacturing methods, such as sheet metal forming techniques or injection molding.

  • Patent number: 5069028
    Abstract: Each of the links consists of a lamina (1) in the form of a strip which, by way of transverse bends (P1, P2), forms a flat link which is closed by way of pairs of tongues (10) abutting halfway through the thickness of the link, said pairs of tongues being spaced apart; the strip has two openings (3) centrally which border an articulation crosspiece (5) which they themselves form, as well as a lateral articulation extension (7) which is aligned with said articulation crosspiece (5), and each link is articulated to that adjacent to it by means of the pairs of abutting tongues (10) which engage on said articulation crosspiece (5) and on said lateral articulation extension (7), in order that each link is thus staggered in relation to those adjacent to it.

  • Patent number: 4750325
    Abstract: A chain link having a pair of curved extremities and being generally in the shape of an elongated loop. The loop defines two sides which converge towards the middle of the link where the two sides are rigidly jointed together, as by a weld, thereby forming a pair of interior spaces progressively narrowing towards the middle. Such link is adapted for use in alternation with pin links in a chain designed to remove waste material in a livestock enclosure. A method of making the link is further disclosed.

  • Patent number: 4578941
    Abstract: An overload detection and safety arrangement for a load carrying link chain, including a fuse link having link plates connected by a fuse bar of a tensile strength less than the tensile strength of the remainder of the load carrying chain, the fuse link being laced into the remainder of the chain. The fuse bar is designed to break under predetermined overload conditions, but is positioned and arranged to carry normal tensile loads on the device. A safety link, offset from but substantially parallel to the line of tension through the fuse bar, connects the link plates. The safety link has a tensile strength greater than the tensile strength of the fuse bar and at least substantially equal to the tensile strength of the remainder of the chain, the safety link holding the load when the fuse bar breaks due to overload conditions.

  • Patent number: 4423591
    Abstract: This disclosure is directed to a link for a bracelet, wrist watchband or the like which is formed of one or more elements defining a body having opposite longitudinal and transverse edge portions, one of the longitudinal edge portions defining a transversely outwardly directed projection and the other of the longitudinal edge portions defining a recess generally aligned with and contour to the configuration of the projection. A slider is mounted for reciprocal sliding movement in a guide channel disposed transversely of the body and opening outwardly through one or both of the opposite longitudinal edge portions. A spring biases the slider in an outward direction.

  • Patent number: 4353459
    Abstract: An endless conveyor chain is a sequential assembly of block links formed of a polymeric material, interconnected by thin fleixble links of undulated shape, formed of either metallic or polymeric material, which are easily capable of flexing through their thicknesses, making it possible for the chain to negotiate lateral turns in the conveying run by producing edgewise flexure in the links. Large bearing stresses, which normally result in applications where chain joint lateral articulation occurs in nonlinear chain travel, are minimized or eliminated since the requisite lateral movement is allowed by flexure in the thin links away from the chain joints.

  • Patent number: 4122666
    Abstract: Each chain link is punched out of a plastic sheet. The link has a closed form with a central opening and is divided on a line at one end of the opening. The link ends at the dividing line have interengaging shapes preventing separation as long as the link ends remain in the same plane. The plastic material can be flexed to spread the link laterally of the faces in joining one link to another. A slot in each link at the opposite end from its dividing line receives an adjacent link to hold the interlocking ends thereof in the same plane to thus prevent separation. The links are variously shaped to achieve different decorative effects.
