U.S. Pat. No. 8,590,112 appears to disclose a cable tie having a head for receiving a tail for binding various objects wherein a head of an integral buckle is tilted so that the tail portion is more easily received. By employing a tilted head, of preferably 30 degrees, a 15-20% increase in performance over similar cables ties of the prior art has been achieved. In addition, a cable tie is provided that includes a bulged or coined portion. A leading edge of the band that is associated with the buckle also includes a bulged or coined portion. The bulged portions are preferably created by a coining process and facilitate binding mechanically the band to the buckle. In addition, a cable tie is provided wherein a head of the integral buckle is interconnected to the band via angled side walls. The angled side walls increase an opening in the buckle that receives the band such that during tensioning less energy is needed to tension the cable tie around, for example, a bundle of cables.
U.S. Pat. No. 8,276,244 appears to disclose an elastomeric releasable cable tie having a head and a strap extending from the head. The head includes an end wall, an inner wall and sidewalls. The end wall, inner wall and sidewalls define a channel that extends from an entrance end to an exit end of the head. The head also includes a hingeless wedge extending from the end wall into the channel for engaging the strap.
U.S. Pat. No. 7,464,442 appears to disclose a tie for the bundling of one or more articles. A deformable tie has an elongate strap including an elongate tail at one end and a locking head at the other end. The locking head includes a pair of holding tabs defining a passageway therethrough and slot spaced from the holding tabs having a raised wall. The tie is placed about the articles to be bundled. The tail is inserted through the passageway of the holding tabs in a first direction. The tail is then passed through the slot in the first direction. The tail is bent around the raised slot wall so as to extend in a second direction opposite the first direction. The tail is then passed through the passageway of the holding tab in the second direction and the tail is bent around the holding tab so as to extend back in the first direction.
U.S. Pat. No. 7,337,502 appears to disclose a fastening system that comprises an elongate strap body having a pair of opposed side portions and a top surface between the side portions. The fastening system also includes a plurality of spaced male protrusions extending therefrom the top surface of the elongate strap body a protrusion height. Each protrusion includes two faces and a protrusion axis, which is substantially perpendicular to the longitudinal axis. The fastening system comprises the ability to form a slit in the top surface of the strap body at almost any location. The slit may generally extend between the pair of side portions, substantially parallel to the protrusion axis and between adjacent male protrusions. The slit may also include end segments extending substantially parallel to the longitudinal axis of the elongate strap body, forming a “tongue.”
U.S. Pat. No. 6,745,439 appears to disclose a cable tie that includes an integral cable tie head and strap. The strap includes a first end forming a neck section, a free end opposite the first end, and an intermediate section between the first end and the free end, the intermediate section having a predetermined width B1 and thickness T1 defining a predetermined cross-sectional area. The cable tie head is secured to the neck area of the strap at the first end of the strap, the cable tie head having a width E that is wider than strap width B and including a strap accepting channel containing a locking device. The strap accepting channel is sized to receive the free end of the strap. The neck section has a width that transitions from a width of B to a width E′ that is substantially the same as width E and a thickness T2 that is thinner than T1, the neck section having a cross-sectional area that is at least substantially equal to the cross-sectional area of the intermediate section of the strap so as to have a tensile strength at least equal to a tensile strength of the intermediate section of the strap. The cable tie may be a bent neck type cable tie. Preferably, the neck section has at least one recessed channel defining the reduced thickness T2 and thickened side portions.
U.S. Pat. No. 6,185,792 appears to disclose a one-piece bi-directional cable tie for bundling articles having a tail at one end, a locking head at the other end and an elongate strap body therebetween that feature one or more fixed locking teeth opposite a deflectable locking pawl so as to provide ratcheting locking engagement with the two major surfaces of its strap body. The fixed teeth may provide symmetrical performance characteristics or may provide selectable performance characteristics depending on the direction of strap body insertion through the locking head. The locking head may facilitate wedging the strap body against the deflectable pawl. The deflectable pawl may include a chevron-shaped upper surface so as to provide an undercut surface for improved engagement with the locking teeth of the strap body.
U.S. Pat. No. 6,185,791 appears to disclose a releasable cable tie including a head, a tail, and an elongate strap body therebetween having plurality of teeth thereon. The head includes a passageway for receiving the tail and strap body and a slot formed in one sidewall which is in communication with the passageway, the strap body being insertable into the passageway in a locking direction for forming a loop to receive the objects to be bound. First and second shoulders are integrally attached to the first sidewall on opposite sides of the slot in opposing relation. The shoulders include first and second upwardly extending reinforcing extensions, respectively, which are each spaced a predetermined distance from the first sidewall so as to create an interstice between the extensions and first sidewall. A bridging member extends between the first and second shoulders. The head further includes a latch for releasably retaining the strap body within the head which is pivotally mounted on the bridging member and has at least one locking tooth complementary to each of the plurality of teeth on the strap body. The latch extends into the passageway through the slot such that the locking tooth engages a selected one of the plurality of teeth for substantially preventing movement of the strap body in a release direction. When the cable tie is under load in a locked position, the first and second reinforcing extensions deflect to engage the first sidewall for adding strength to the latch which enables the tie to withstand greater tensile forces. Because the latch is pivotal about the longitudinal axis of said bridging member, it may be pivoted to release the locking tooth from engagement with the selected one of plurality of teeth to permit the strap body to be moved in the release direction, the strap body being easily releasable from the head thereby allowing the tie to be reusable.
U.S. Pat. No. 5,836,053 appears to disclose a one-piece cable tie for forming a plurality of objects such as cables into a bundle that includes an elongated flexible strap having a top planar surface, a bottom planar surface, a first end and a second end. The strap further includes a plurality of transverse raised cross-members projecting up from the top planar surface, said raised cross-members being spaced along the length of the strap and defining therebetween a plurality of openings. A locking head is integrally formed to the first end of the strap. The locking head includes an outer end wall, an inner end wall and a pair of sidewalls which together define a generally rectangularly shaped strap accepting channel therebetween. A holding tab is disposed within the locking head and projects out from the inner end wall and into the strap accepting channel. The outer end wall is shaped to include an angled locking face. In use, after the second end of the strap has been inserted through the strap accepting channel and drawn tight around a bundle and the insertion force is thereafter relaxed, the stored pressure of the bundle by virtue of its configuration pivots said strap causing the rear surface of one of the raised ratchet teeth to abut against the angled locking face to lock the strap in place. At the same time, the holding tab engages with one of the openings in the strap to oppose deliberate release of the raised ratchet tooth from the locking face.
U.S. Pat. No. 4,958,414 appears to disclose a reusable tie-all or bundle fastener, which comprises a single strap, made of plastic material with a socket having a passageway therethrough at one end of the tie, and a tongue with ratchet teeth on the other end adapted to slip through the passageway in the socket. There is a locking pawl in the socket which is pivoted to the socket and which has a lever so that it can be raised to release the pawl from between the strap teeth when a loop is formed from the tie-all so as to release the tie. Two or more ties can be used in combination to form an enlarged loop.
U.S. Pat. No. 4,896,402 appears to disclose a clamping device in the form of a one-piece cable tie. The cable tie includes a band section having a free end for positioning about an object to be constrained, such as an electrical cable, and a buckle section through which the free end of the band section is inserted. In a preferred embodiment, the buckle section includes a first portion operatively connected to the band and terminating adjacent a slot. A second, raised portion of the buckle section is longitudinally or horizontally offset from the first portion. The second portion extends from a point adjacent the aforementioned slot to a free end. The width of the slot occupied by the band is greater when the band is loosely wrapped about the object constrained. The greater width of the slot when the band is loosely wrapped facilitates single or multiple wrappings of the object constrained. Any gaps between the band the object constrained are reduced by positioning only the first portion of the buckle section adjacent the object thereby improving clamping. Lips are also provided on the buckle section to accommodate positioning of the buckle section in a grooved area formed in the object being constrained. The cable tie is preferably made by a machining process in which buckle sections are alternately formed on opposing sides of a sheet of metal material to enhance the use of the material and avoid waste.
U.S. Pat. No. 4,287,644 appears to disclose a coil loop type cable tie of one-piece molded plastic construction having a flexible strap and a fastening head at one end thereof. The fastening head has a passageway running parallel to the strap and a hinged pawl extending into the passageway and having at least one tooth adapted to mesh with ratchet teeth on one side of the strap. The hinged pawl is connected to the fastening head by hinge which defines the closed end of a notch separating the hinged pawl from the rest of the fastening head. The notch opens onto a surface of the hinged pawl opposite to the surface on which its tooth or teeth are formed and preferably angles from its closed end to its open end generally toward the strap.
U.S. Pat. No. 3,660,869 appears to disclose an integral one-piece cable tie including an elongated flexible strap having a row of teeth thereon, a frame integral with one end of the strap and having an abutment wall and an end wall and an entry surface and an exit surface and a strap-receiving opening therethrough, a ledge on the end wall, and a pawl pivotally mounted on and integral with the ledge within the opening and having a set of teeth shaped complementary to the row of the teeth and defining with the end wall a strap-receiving throat disposed normal to the longitudinal axis of the strap as molded.
