Definitions

  • the present invention concerns an anchoring means. More specifically, the present invention concerns an anchoring means of the expansion type. Still more specifically it concerns an expansion anchor which is variable in its overall length.
  • Expansion anchors of the type insertable in a bore or the like provided in masonry or other walls, and which is then radially expanded so as to frictionally engage the circumferential wall of the bore are well known.
  • Another object of the invention is to provide an ex pansion anchor whose axial length is selectively variable.
  • I provide, in an expansion anchor, an elongated sleeve having an annular first end portion, a slotted second end portion defining a plurality of tongues and being expandable in response to internal expanding stresses, an intermediate portion between said first and second end portions, and a weakened portion between said first end portion and said intermediate portion, said weakened portion being adapted to buckle outwardly in response to axial compressive stresses, and a combined expanding and shortening member adapted to initially expand said second end portion and to subsequently exert axial compressive stresses on said weakened portion whereby said weakened portion will buckle outwardly and the overall length of said sleeve will thereby be reduced.
  • the elongated sleeve which is preferably made from a resilient plastic material, such as a slow-aging polyamide, with an end portion which is insertable into a bore in a wall or the like, and a free end portionvwhich will be located outside the bore.
  • the end portion which is located outside the bore is axially slotted so that, when a screw shorter than the sleeve is being used, rotation of the screw in a sense which tends to insert the same deeper into the elongated sleeve, will cause axial compressive stresses to be brought to bear on the free end portion so that the same will buckle outwardly and thereby reduce the overall length of the sleeve. It will be seen that a short screw,
  • the expansion anchor according to the present invention thus is capable of automatically adapting itself to various screw lengths.
  • the inventive expansion anchor can also be used to secure corrugated covering materials, such as corrugated sheet materials, to a wall or a roof. It is essential that such materials do not leak and sealing of the openings for the fastening means used has always presented a problem. With the inventive construction the opening through which the expansion anchor sleeve is inserted in these corrugated materials is reliably sealed by tight engagement of the flange of the sleeve with the material.
  • FIG. 1 is a partly sectioned elevational view of an expansion anchor of the present invention, used to secure a corrugated material having a steep pitch of corrugation to a wall;
  • FIG. 2 is a view substantially similar to that of FIG. 1 and shows the inventive expansion anchor in use with a corrugated material having a lesser pitch of corrugation;
  • FIG. 3 is a partially sectioned elevational view of a portion of the inventive anchor showing how the flange of the sleeve acts as a seal for the inserting opening.
  • the elongated sleeve 1 is formed with an inner end portion 1a adapted to be inserted into a bore in a wall or the like.
  • the outer end, that is that end which will remain outside the bore, of the sleeve 1 is formed with a weakened portion 2.
  • the inner end portion 1a is axially slotted as indicated by reference numeral 3, these slots extending toward but short of the weakened portion 2.
  • the latter is also axially slotted toward but short of the inner portion 1a.
  • the formation of slots 3a in the portion 2 creates a plurality of elongated ribs 2a (see FIG. 2).
  • the sleeve is formed adjacent its free end with an annular free end portion 4 and in turn this end portion 4 is formed with a flange 5 extending transversely of the direction of elongation of sleeve 1. As shown in FIG. 3 the flange 5 will act as a sealing element to reliably prevent the entry of moisture through the insertion opening through which sleeve 1 extends.
  • Sleeve 1 is inserted into a bore 8 formed in a wall or the like 9.
  • the sleeve shown in FIG. 1 serves to secure a corrugated member 6 having a relatively steep pitch of corrugation to the wall 9.
  • the sleeve 1 is inserted through an opening 6 formed in the member 6 and extends into the bore 8 of wall 9.
  • a correspondingly long screw 7a is inserted into the sleeve 1. The screw 7 is then rotated in a threadengaging sense until its head 7 engages the flange 5 of sleeve 1.
  • the transverse flange 5 of sleeve 1 serves as a sealing element to seal the opening through which the expansion anchor sleeve is inserted. This is shown in FIG. 3 from which it will be plain that the head of screw 7 will so displace the flange 5 into contact with the underlying material that a tight seal is established.
  • an elongated sleeve having a peripherally continuous annular end portion at one end of said sleeve, a slotted second end portion at the other end of said sleeve defining a plurality of tongues and being expandable in response to internal expanding stresses, a peripherally continuous intermediate portion located adjacent to said second end portion but spaced from said first end portion, and a longitudinally extending weakened portion located between said first end portion and said intermediate portion, said weakened portion being adapted to buckle outwardly in response to axial compressive stresses whereby, when such stresses are exerted on said sleeve, said weakened portion will buckle outwardly and the overall length of said sleeve will thereby be reduced.
  • peripherally'continuous annular end portion is provided 1 with a flange extending transversely of the elongation of said sleeve; said combined expanding and shortening member having a head adapted to engage said flange subsequently to expansion of said second end portion by said member, and to exert said axial compressive stresses on said flange and thereby on said weakened portion.
  • said combined expanding and shortening member further having a stem integral with said head and adapted to extend through said sleeve and to engage said intermediate portion, said stem having a terminal portion spaced from said head and adapted to initially expand said slotted second end portion prior to engagement of said flange by said head.
