  • Patent number: 8083454
    Abstract: A U-shaped connector (10) for connecting together abutting or adjoining timber elements includes a stem portion extending between two kinked spike portions (14,16) with each spike portion (14,16) extending in a common direction from the stem portion. Each kinked spike portion (14,16) is comprised of four straight portions (15,18,20,22 and 17,19,21,23) of equal length joined end-to-end, with each straight portion extending at an angle to its adjacent portion. Distal ends (24,25) of each tip portion (22,23) are sharpened and splayed wider than the stem portion. On installation, the flexibility of connector (10) is sufficient to provide a compressive force to the abutting faces of the timbers being joined with the kinked spike portions (14,16) moving outwards away from each other so as to increase the connector's pull out resistance.

    Abstract: A staple (4) for a delicate material (22) comprises two flexible legs (46, 47) between a head portion (56) connecting the legs and an introduction end portion (57). Between the head and end portions is located a discontinuity portion (58) so that when the staple is pushed into the material (22), at least one of the legs (46, 47) inclines with respect to the head portion (45) and thus ensures good resistance to extraction. The two legs (46, 47) are bent (76, 77) inwardly in the discontinuity portion (58) of the whole assembly to diverge from one another upon fixing the staple to the delicate material.

  • Patent number: 5695524
    Abstract: A staple and stapler for injecting the staple in a manner so that the staple maintains a near constant width upon penetration of material to be joined and during staple closure/forming such that material perturbation and staple to staple spacing may be minimized. The staple has a rectilinear bridge part from which depend oppositely positioned side parts and from the side parts a pair of straight legs. In a preferred embodiment, the oppositely positioned side parts consist of a proximal arcuate section attached to the bridge part and an oppositely directed distal arcuate section attached to the legs. The legs may have sharpened points. Also disclosed is a stapler adapted to force the oppositely directed distal arcuate sections outward, in one embodiment, thereby forcing a reaction of the legs of the staple to face each other in linear alignment and form a closed staple.

  • Patent number: 5392978
    Abstract: An improved staple for use with an endoscopic stapler has arms which are curved toward each other such that the staple may be crimped so as to cause the arms to move toward each other and thereby lock the staple into place. This crimping action substantially mitigates the likelihood of the staple inadvertently pulling out. The staple also has an abutment bend formed therein to serve as a detent and thereby secure the staple within the jaws of an endoscopic stapler. An endoscopic stapler for effecting use of the improved staple is also disclosed. The endoscopic stapler generally comprises an elongate tubular section which may be inserted through an endoscopic incision into a human body; a handle portion having a trigger for effecting the stapling process; a pair of jaws disposed at the distal end of the elongate tube for positioning and crimping a staple in place; a feed mechanism for advancing a series of staples to the jaws; and a means for selectively adjusting the amount of crimp imparted to the staple.

  • Patent number: 4955898
    Abstract: A surgical staple has a base portion and a pair of leg portions respectively extending angularly from the opposite ends of the base portion. Each leg portion has at its distal end portion a first inclined surface and a second inclined surface extending from the first inclined surface to the distal end of said leg portion. The first and second inclined surfaces are inclined with respect to the axis of the leg portion. The angle between the first inclined surface and the axis of the leg portion is smaller than the angle between the second inclined surface and the axis of the leg portion. The second inclined surface terminates in a sharp edge at its distal end. For producing the surgical staple, a blade is moved toward each of the leg portions in inclined relation to the axis thereof to shear the leg portion, so that a smooth sheared surface and a coarse ruptured surface are formed on the distal end portion of the leg portion and arranged in this order toward the distal end of the leg portion.

  • Patent number: 4637194
    Abstract: An I-beam or joist is formed of a pair of horizontal, parallel wood chords connected together by a wood web. The lower chord is pre-stressed by holding it in compression during assembly of the chords and web. The chords are fastened to the web by U-shaped wire staples whose legs have bevels formed on their free ends which cause the legs to move towards each other and to cross the central axis of their respective staple as they longitudinally penetrate thewood during insertion through a chord and into the wood web. Further, plates are fastened upon the opposite faces of the web at the opposite ends of the web, thereby increasing the web thickness at the opposite ends of the beam to substantially increase the allowable shear stress limits of the beam.

  • Patent number: 4380414
    Abstract: An improved fastener is provided with retainer elements which are utilized to prevent undesired movement of the fastener relative to an associated member. In one embodiment of the invention, the retainer elements are resiliently deflectable spring fingers having free end portions which penetrate the associated member to prevent reverse rotation of the fastener, that is rotation of the fastener in a direction tending to loosen the fastener. When the threaded fastener is being rotated in a first direction to tighten it, the spring fingers are deflected into recesses formed in the fastener to prevent gouging or marking of the member. Upon the application of a force tending to loosen the fastener, the free end portions of the spring fingers penetrate the member and dig in to prevent loosening movement of the fastener. In another embodiment of the invention, the retainer elements cooperate with an associated member to prevent both axial and rotational movement of the fastener relative to the member.

  • Patent number: 4297064
    Abstract: A staple-nail fastener for nailing a ceiling support strip to a panel of wallboard which consists of a length of relatively hard steel wire bent into "U" shape to form long and short legs approximately parallel to one another, the long leg being approximately one-quarter inch to approximately three-eighths of an inch longer than the short leg. The long leg is chamfered to a sharp point, while the short leg presents a tip which is less sharp so that when the fastener is hammered into the strip the long leg readily penetrates the strip while the short leg resists penetration, serving as a fulcrum for the long leg to impart broadwise swinging movement thereto so that, as the long leg continues its penetrating movement, it regionally compresses the wallboard in the direction of the strip, until the short leg assumes a final position in which it lies flatly and snugly against the strip.
