Abstract: A vehicle mounted securing system is described. A rack is secured to the vehicle. Oblong slots formed in the rack provide a variety of locations at which to secure items to the racks. Brackets, strap mounts and the like are easily and removably attached to the rack by specially shaped disks or pucks which fit within the contours of a slot. Items may be secured by one or more bracket-puck combinations inside or outside of the vehicle.

Abstract: A fastener assembly for securing two components to one another. The fastener assembly includes a barrel or pin that has a radially extending hole in the barrel. The pin also has a reduced diametrical portion on at least one end to form a shoulder and possibly on both ends. The pin is inserted into a hole formed into a hollow or sandwich component. The shoulder engages against a wall on the component to orient and secure the pin in the hole. A threaded fastener is then inserted transversely through the two components to engage in the radially extending hole. The threaded fastener is then rotated to secure the two components to one another.

Abstract: A two-piece locking nut assembly for securing a mantle to a head assembly of a cone crusher. The two-piece locking nut assembly includes an inner nut and an outer nut. The inner nut includes a set of axial bores that each receive a jackscrew. Once the locking nut assembly is in position on the head assembly, the series of jackscrews are tightened to exert a force on the mantle that is counteracted by forces through the inner nut and into the head to create a locking force between the locking nut assembly and the head assembly. The outer nut is turned along the inner nut to hold the locking nut assembly in place. Once the outer nut is moved into position, the jackscrews are removed such that the outer nut continues to apply the locking force between the mantle and the head through the locking nut assembly.

Abstract: A self-locking nut is described for securing components for spectacles, including a body with an internally-threaded through-hole extending along an axial direction, the body having at least one recess extending transversely to the axial direction and intersecting at least partly the threaded hole, the recess delimiting at least a first and a second portion of the body connected together and axially separated. The main parts of the sections of the threaded hole of the respective first and second portions are axially misaligned in relation to each other along the axial direction and arranged so as to return in substantially reciprocal alignment when the portions are screwed onto a threaded shank. Elastic deformation generated in the portions of the nut, as a result of the return to the aligned position of the threaded sections, being such as to increase the tightening action of the nut on the threaded shank.

Abstract: A locking threaded bolt is provided whose head has an inclined seat surface. The angle of the incline of the head seat surface is such that when the bolt is tightened to a predetermined torque within a threaded hole, the entire seat surface is in contact with the upper surface of an article to be fastened, and a shearing stress is applied to the shank of the bolt in a transverse direction. This shearing stress causes reduced clearance between the threads of the bolt and the threads of the threaded hole, thereby firmly locking the bolt in the hole and preventing loosening of the bolt.

Abstract: A seat adjustment mechanism for adjustably connecting a seat to a chair base is provided wherein a threaded spindle is secured to the seat and rotatably and axially movably received within a column member extending upwardly from the chair base. An adjusting nut is threadedly engaged with the spindle and supported within the column member by a bearing assembly, and which is upwardly urged by a compression spring such that the upper surface of the adjusting nut lockingly engages a downwardly facing engaging surface of a lock cap in the column member when the seat is unoccupied. By rotating the seat and the spindle secured thereto, vertical adjustment of the seat is provided. When the seat is occupied, the adjusting nut is moved downwardly by the spindle and against the bearing assembly to compress the spring and disengage the upper surface of the adjusting nut from the downwardly facing engaging surface. The seat and spindle then may be rotated without being vertically adjusted.
