  • Patent number: 5741100
    Abstract: A fixing element has a shank having a rear end and a leading end, a holding element arranged on the rear end of clamping an article to a building component, at least one expansion region extending from the leading end in a longitudinal direction for part of a length of the shank. The expansion region is formed by a longitudinal slot with a base surface raising toward the leading end. A expansion member is inserted in the longitudinal slot. The base surface slopes upwardly and ends at an outer circumference of the shank at a distance from the leading end. The expansion member is formed as a wedge with a length substantially corresponding to a lenght of the longitudinal slot and lies on the base surface so as to be displaceable toward the leading end. The wedge has an outer surface provided with roof-shaped teeth which project beyond the shank at least by a part of a height of the teeth.

  • Patent number: 5664920
    Abstract: A fixing element has an expansion zone formed by a longitudinal slot having a trapezoidal cross-section and produced by stamping, and an expander member inserted in the longitudinal slot and displaceable therein. On the two sliding surfaces of the longitudinal slot arranged at an angle to one another the expander member rests with its two bearing surfaces, likewise arranged at an angle to one another. The external surface of the expander member provided with teeth of roof-shaped construction projects beyond the shank of the fixing element at least with a part of the height of the teeth. The expander member lying in the longitudinal slot so that it is easily displaceable allows subsequent expansion of the anchored fixing element in the event that the drilled hole widens as a result of cracks forming.

  • Patent number: 5562376
    Abstract: A nail-like fixing element has a shank having a rear end and a front end, and a retaining element provided at the rear end of the shank for clamping an article to a component. The shank has at least one expansion zone extending from the front end in a longitudinal direction of a part of a length of the shank and being formed by a free space. An expansion element is inserted in the free space. The space is formed as a U-shaped longitudinal slot with a base which slopes up toward the front end. The expansion element is formed as a wedge which is located in the longitudinal slot on the base so as to be displaceable towards the front end. The wedge has an outer face provided with teeth which project beyond the shank.

  • Patent number: 5344268
    Abstract: The anchor for anchoring in a drilled hole in concrete via a joining composition, includes a threaded bolt consisting of a straight shank portion having an expander cone at one end thereof to be inserted in the drilled hole and a threaded portion at the other end, the expander cone having an outer surface and an end face and widening toward the end face; an expandable sleeve arranged on the threaded bolt enclosing the expander cone and structured to be expanded by the expander cone and a plastic covering on the end face and the outer surface of the expander cone and an adjoining part of the straight shank portion. The complete plastic covering over the expander cone and the adjoining part of the straight shank portion ensures that the joining composition does not bond the expandable sleeve to the threaded bolt, thus hindering subsequent expansion of the expandable sleeve by the expander cone due to crack formation at the drilled hole.

  • Patent number: 5342157
    Abstract: An impact-type expansible plug for anchoring in a cylindrical drilled hole of a concrete part and the like has an expansion sleeve provided with at least one longitudinal slot and expandable in a drilled hole, and also has an expansion sleeve with a conically narrowing internal bore, and an expansion mandrel drivable into the conically narrowing internal bore of the expansion sleeve. The expansion sleeve has a forward end provided with an annular collar having a radially directed circumferential cutting edge, and also has a portion tapering toward the annular collar.

  • Patent number: 5328300
    Abstract: An anchoring means for anchoring by a bonding mass in a drilled hole in a concrete part or the like has a threaded bolt with a reduced portion and an expansion cone followed by a head part, forming at the same time a stop shoulder. Over the reduced portion and expansion cone is slipped an anchoring sleeve which is provided on its outer surface with a plurality of longitudinal grooves. By the longitudinal grooves and the elasticity of the anchoring sleeve consisting of plastics material, the possibility is obtained of compensating for the enlargement of the drilled hole when a crack forms, thus making it possible for the anchoring means to be used in the zone subject to tensile forces.

  • Patent number: 5314277
    Abstract: The expansible plug has an expander body at one end of a plug shank and an expansible sleeve which slids over the expander plug in operation. A sliding ring is often provided between the expander body and the expansible sleeve to improve the sliding properties of the expansible sleeve over the expander plug. To prevent slippage of the sliding ring off the expander plug, the sliding ring can be provided with an interlocking inner profile which engages in an outer thread or a plurality of annular steps on the outer surface of the expander body. The expansible plug can be used to attach objects to a masonry wall by inserting the expansible plug into a drilled blind hole with the expander body at the base of the hole and a fixing means which may include a threaded portion on the shank protruding from the hole.

  • Patent number: 5230595
    Abstract: The expansible plastic fixing plug consists of a plastic body provided with a slot beginning at the front end of the body and extending longitudinally over a portion of the length of the body in a plane passing longitudinally through the body. The plastic body is provided with a longitudinal bore starting from the rear end for insertion of a fixing screw having an outer diameter. The longitudinal bore has a cylindrical portion having an inner diameter corresponding approximately to the outer diameter of the fixing screw and a narrowing portion ending at the slot. To reduce the insertion resistance for the fixing screw the narrowing portion narrows in a direction at right angles to the plane in which the slot extends and has a width in the plane along its length approximately equal to the inner diameter of the cylindrical portion.

  • Patent number: 5193957
    Abstract: The fixing element for securing an article on a base material includes a shank having a shank portion for receiving an article to be fixed, a reduced diameter portion having opposite ends including a free end and an expander cone located at the free end; and an expansible resilient sleeve received on the reduced diameter portion and having at an end remote from the expander cone lugs which are bent inwards at one obtuse angle. The lugs have end surfaces facing a transition shoulder between the other end of the reduced diameter portion and the shank portion. The expansible resilient sleeve has a length greater than the length of the reduced diameter portion. The expandsible resilient sleeve also has, in an unstressed condition, a sleeve outer diameter larger than the shank portion diameter and a sleeve inner diameter larger than said reduced diameter portion diameter.
