| 411032000 | Made up of plural expansible segments or sections | 11 |
| 20100272536 | DOUBLE COLLAR WEDGE ANCHOR - A solid masonry and hollow block fastening device that uses two expansion collars to secure a fastening thereof in varied masonry materials. In greater particularity, the two expansion collars are interconnected by a bridge of a unitary construction therewith in order to enhance the strength and holding power thereof when mounted on masonry material. | 10-28-2010 |
| 20110058915 | FASTENER ASSEMBLY - A fastener adapted to join a first component to a second component. The fastener includes a first connecting end adapted to engage a slot opening in the first component, and a second connecting end adapted for press-fit insertion into an opening in the second component. The first connecting end includes a raised edge collar defining a concave surface facing away from the second connecting end and an opposing platform surface disposed above the raised edge collar in spaced relation to the raised edge collar with a post member extending between the raised edge collar and the opposing platform surface. The first connecting end is adapted to hold the first component in sandwiched relation between the raised edge collar and the opposing platform surface. The raised edge collar includes a segmented perimeter wall including a plurality of cut-outs defining substantially independently flexible segments between the cut-outs. | 03-10-2011 |
| 20120087762 | FASTENER AND STRUCTURE FOR FASTENING A MEMBER TO BE FASTENED - To obtain a fastener, and a structure for fastening a member to be fastened, with which a sufficiently locked state can be maintained even when the male member is pushed from the back. | 04-12-2012 |
| 20130156525 | BLIND FASTENER - A blind fastener adapter for a conventional screw-threaded nut and screw comprises a collar and a segmented ring over the collar, the ring and collar having a tapered interface wherein relative axial movement results in a change of diameter of the ring. The adapter further includes a spring adapted to bias the collar and ring into mutual engagement; the collar and ring include means to prevent substantial relative angular movement thereof. The collar is adapted for engagement by a blind side head of the screw in use, and the ring is adapted for blind side engagement of the perimeter of a hole. | 06-20-2013 |
| 411033000 | Identical segments | 7 |
| 20080219797 | Rivet - The invention relates to a rivet for connecting parts, in particular aircraft components, penetrated by bores, comprising a sleeve part ( | 09-11-2008 |
| 20090214315 | Drop-in anchor for concrete structures - A radially expansible sleeve to provide part of a drop-in anchor for receipt in a bore formed in a concrete structure. The sleeve has arcuate protrusions with knife-like distal edges extending therearound. Upon radial expansion of the sleeve, the knife-like edges cut into the interior surface of the bore to anchor the sleeve in place. | 08-27-2009 |
| 20090324360 | CONNECTING MEMBER - A connecting member for two parts includes a first half ( | 12-31-2009 |
| 20100221085 | Monarch anchor - The Monarch anchor is a nut & bolt system specially designed to be pushed through a hole wide enough to allow the bolt with collapsed wings fitted at its back end through, but not wide enough to let the bolt with stretched wings slip back. It is designed to be firmly placed on the wall with the front end of the outer nut locked at the front surface of the wall by a flange and the stretched wings locked at the back surface of the wall. Thus it can act as a firm support on the wall when an item is bolted through the inner nut of the anchor. | 09-02-2010 |
| 20120195707 | Wall Anchor For a Screw - A wall anchor for a screw, including a longitudinal axis, a cylindrical head collar at one end, a cylindrical tail collar at an opposite end, and a plurality of plastically deformable substantially longitudinal bars which connect the head collar to the tail collar. The head and tail collars have internal passages for a threaded screw shaft. The head collar has a transverse flange for abutment with a screw head. The tail collar has a nut for engagement with a threaded screw shaft. The nut includes a stack of at least three rings arranged substantially transverse the axis upon an annular end face of the tail collar. An internal hole though each ring is substantially coaxial with the axis, and a side of each ring is connected to the tail collar by a web. An assembly of the wall anchor and screw, and a method of manufacturing are disclosed. | 08-02-2012 |
| 20150063943 | ELASTICALLY DEFORMABLE ALIGNMENT FASTENER AND SYSTEM - An elastically deformable alignment fastener has the form of a unitary object having a head portion and an integrally formed body portion. The body portion has an elastically deformable lobular hollow tube having a proximal end proximate the head portion and a distal end axially displaced from the head portion. The lobular hollow tube has an outer surface having one or more retention features oriented to provide a plurality of radially extending engagement surfaces along a length of the hollow tube. The head portion has a flange that circumscribes the proximal end of the lobular hollow tube. Portions of the elastically deformable lobular hollow tube when inserted into circular apertures of first and second components elastically deform to an elastically averaged final configuration that aligns the first and second components in four planar orthogonal directions. | 03-05-2015 |
| 20160091007 | REMOVABLE BLIND-HOLE WIDE-EXPANSION WEDGE FASTENER - A removable and selectively radially expandable fastener device includes a body and at least one expanding arm located on each end of the body. The at least one arm on each end of the body is selectively moveable radially in relation to a longitudinal axis of the body. Such movement can be manually activated by rotating a fastener or torsion member, thus moving a washer axially to rotate the at least one arm radially. | 03-31-2016 |
