127 Clamping Sleeve and Clamp Connection US11885635 2006-03-06 US20090162164A1 2009-06-25 Harald Bohl
A clamping stub 10—to detachably hold in place elongated construction components 30 at a support 20 which is fitted with at least one continuous, threaded hole 25—comprises a stub shank (12) which can be screwed into said hole and is fitted with an inside space 22 congruent with the component 30 that can be slid into it in close-fit manner. The stub shank 12 comprises an external thread 14 fitted with at least one axis-parallel slit 16. The nominal diameter of the external thread 14 equals that of the threaded hole 25. A head 15 of the stub shank 12 is fitted with shaped surfaces 26 on which a tool may be applied and by its flanged surface 24 exceeds the diameter of said external thread 14. The inside space 22 flaring toward its end 13 in particular in conical manner runs as far as into the head 15 or passes through it. Clamping stubs 10 devoid of a head and of which the shank length at most equals the thickness of the support 20 may be used for a tubular or flat-steel support 20 fitted with at least one continuous, threaded hole 25 subtending an angle to said support. The components to be affixed to said support may be railing bars, tubes/pipes or the like. Double clamping stubs 35 are appropriate for system connection and for further applications such as slide bearings, shaft-hub couplings shaft couplings and the like, wherein the invention offers the pronounced advantage of clamping force adjustability.

135 Nonrotating, self-centering anchor assembly for anchoring a bolt in a borehole US891069 1997-07-10 US5846041A 1998-12-08 John E. Bevan; Grant W. King
An expandable anchor assembly is provided for anchoring the threaded end portion of an elongated roof bolt in a borehole. The anchoring assembly includes a hollow outer sleeve in the form of a plurality of symmetrically arranged, longitudinal segmented wall portions with exterior gripping teeth and an inner expander sleeve in the form of a corresponding plurality of longitudinal wall portions symmetrically arranged about a central axis to define an inner threaded cylindrical section. The inner sleeve is captured within and moveable axially relative to the outer sleeve. As the threaded end portion of the elongated bolt is inserted into the inner threaded cylindrical section of the inner sleeve from the trailing end to the leading end thereof, the inner sleeve expands over and clamps around the threaded end portion of the elongated bolt. Thereafter, partial withdrawal of the elongated bolt from the borehole causes the inner sleeve to axially move relative to the outer sleeve from the leading end toward the trailing end of the outer sleeve in a wedging action to cause the outer sleeve to radially expand and force engagement of the gripping teeth against the sidewall of the borehole to thereby secure the expandable anchor assembly and therewith the threaded end portion of the elongated bolt within the borehole.
136 Machine screw US785687 1997-01-17 US5755543A 1998-05-26 James E. Culpen
An improved machine screw for engaging a correspondingly threaded aperture, comprising a threaded shank having a proximal portion and a distal portion. A head adapted to be rotated may be formed on a shank proximal end opposite the shank distal portion, such that the shank extends axially therefrom. The shank is deformable from a first position to a second position, for either (1) minimizing the contacting surface area between the shank and said aperture, and thereby allowing the machine screw to be easily insertable into said aperture, or (2) maximizing the contacting surface area between the shank and said aperture after the shank has been fully inserted into said aperture, and thereby making the hold between the screw and said aperture more secure. Such deformation of the screw occurs during its insertion into said aperture. It has been found that this deformation prevents screws of the present invention from seating improperly within threads of said aperture. Furthermore, the screw may be formed of a resilient material for allowing it to deform again as it is extracted from said aperture, and even to reform into its original shape after it has been thus extracted. The shank further includes an elongate, open-sided slot extending axially from the shank distal end toward the shank proximal end, for dividing at least a portion of the shank into at least two elongate shank legs.

138 Quick fastener US77760 1993-06-17 US5292217A 1994-03-08 John G. Korpi
Disclosed is a quick fastening quick releasing nut-and-bolt assembly in which the bolt has finger elements disposed along the bolt's longitudinal axis. The finger elements have sets of accurate thread segments matable with complimentary sets of radially inward facing arcuate thread segments on the inner diameter of a nut. The nut's inner diameter includes smooth semi-cylindrical surfaces circumferentially alternated with the nut's sets of thread segments. The nut has a central core body sliding upon radially inner surfaces of the finger elements so as to keep the finger elements in bearing relation with the nut's inner diameter. The assembly has a first, unlocked configuration in which the bolt's thread segments face the smooth surfaces on the nut's inner diameter. The assembly has a second, fastening configuration where the bolt's thread segments are engaged with the nut's thread segments.
