20090092458 | SELF-DRILLING ANCHOR - An embodiment of the invention includes a self-drilling anchor. The self-drilling anchor includes a drill rod with a first end and a second end and a drill bit attached to the first end of the drill rod. The self-drilling anchor also includes an expansion shell located over the drill rod near the first end and adjacent to the drill bit and a rod sleeve located over the drill rod and adjacent to the expansion shell. | 04-09-2009 |
20100034611 | Self-Drilling Masonry Bolt - A self-drilling masonry bolt including a body portion having a bolt member and an outer sleeve portion, a head portion and a drilling tip whereby, the self-drilling masonry bolt provides a simple and effective means for securing an item to cement, wood or any other suitable material without the requirement of multiple tools. | 02-11-2010 |
20100303574 | ANCHOR FOR HOLLOW WALLS - An anchor for mounting to a hollow wall made of friable material comprises a proximal flanged end adapted to be engaged by a rotatable tool to rotate the anchor about a longitudinal axis thereof and to cause is to gradually engage the wall. The anchor also includes a distal end adapted to cut through the wall as the anchor is rotated, and a shank extending between the proximal and distal ends. The shank includes at least one expandable leg that is in a collapsed position thereof when the anchor is rotated to mount it to the wall and that is located distally beyond a non visible surface of the wall once the anchor has been mounted to the wall and is in a first position thereof. The wall anchor includes an outer thread that securely engages the wall. A threaded fastener, e.g. a screw, is adapted to be introduced in the anchor and to threadably engage the same distally of the leg such that sufficient rotation of the threaded fastener retracts the distal end towards the proximal end thereby causing the leg to displace to a laterally expanded position thereof and to engage the non visible surface of the wall. | 12-02-2010 |
20100316465 | METHOD OF ATTACHING SETTING AND USING A SELF-DRILLING ANCHOR SCREW WITH ONE TOOL - A unique self-drilling anchor screw is configured so that it can be set and used to secure a first object to a second object using only one tool to save time and effort. A nut of the screw engages a nut stop when turning in reverse, thereby driving rotation of the screw in reverse. The screw has a drill bit tip adapted for drilling a hole while turning in reverse. A hole is drilled using the drill bit tip while turning the nut in reverse with a socket wrench of the one tool. After drilling the hole, the nut is turned in the forward direction with the socket wrench to engage a sleeve member of the screw, which sets the screw in the second object. Then, the nut is further turned forward using the socket wrench to tighten the nut against the first object located between the nut and the second object. | 12-16-2010 |

20080292421 | Self-drilling wall anchor device - A wall anchor device includes an outer anchor sleeve having an outer peripheral lip, one or more peripheral flanges extended outwardly from the middle portion for engaging with a work piece, an insert engageable into the outer anchor sleeve and having an outer end for being driven by a tool, and a penetrating element attached to the insert to drill and move the anchor sleeve into the wall, the outer anchor sleeve may be expanded and engaged with the work piece, and the penetrating element includes one or more projections for centering the penetrating element relative to the work piece and for removing the drilled materials from or out of the work pieces. | 11-27-2008 |
20100003100 | Self-Drilling Anchor - A self-drilling anchor for use in a friable material or a semi-rigid material comprises a body having an axis, an axial bore adapted to receive a fastener, a proximal end, a drilling end, a proximal portion adjacent the proximal end having high threading having a crest diameter for engaging the friable or semi-rigid material, and a drilling portion adjacent the drilling end, an additional thread proximate the proximal end, the additional thread continuing between turns of the high threading, and a head at the proximal end having an outer diameter that is smaller than the crest diameter. The anchor additional thread is configured to engage either the friable material or, additionally, to firmly engage the semi-rigid material. | 01-07-2010 |
20100239384 | MOLLY BOLT - A molly bolt has a fastener, a sleeve and a tip. The fastener has a head and a shaft. The shaft is formed on and protrudes from the head and has a threaded segment. The sleeve is mounted around the shaft and has a fixing end, a rim, a compressing segment and an asymmetric structure. The fixing end is disposed adjacent to the head. The rim is formed around the fixing end. The compressing segment is formed from and protrudes from the fixing end. The asymmetric structure is a slot or multiple asymmetric slots respectively formed in the compressing segment. The tip is mounted on the connecting end of the fastener. The asymmetric structure causes asymmetric deformation preventing the molly bolt from loosening. | 09-23-2010 |
20110268527 | WALL ANCHOR - A wall anchor is provided and includes a nose cone structure including a body and a primary cone, which is rotatably coupled to the body and manually urgeable to penetrate a substrate, a detent assembly, disposed on the nose cone structure, which is engageable to maintain the primary cone in a first position and a trigger integrally coupled to the nose cone structure and actuatable to selectively disengage the detent assembly such that the primary cone is permissively rotatable about the body into a second position. | 11-03-2011 |

20080292422 | Self-drilling wall anchor device - A wall anchor device includes an outer anchor sleeve having an outer peripheral lip, one or more peripheral flanges extended outwardly from the middle portion for engaging with a wall member, an insert engageable into the outer anchor sleeve, and a penetrating element attached to the insert to drill the anchor sleeve into the wall and to form an aperture in the wall, the outer anchor sleeve may be expanded and engaged with the wall member, and the penetrating element includes a helical protrusion for engaging with the wall member and for evacuating a drilled or material into the aperture of the wall member and for solidly securing the wall anchor device to the wall member. | 11-27-2008 |
20080292423 | Self-drilling wall anchor device - A wall anchor device includes an outer anchor sleeve having an outer peripheral lip, one or more peripheral flanges extended outwardly from the middle portion for engaging with a work piece, an insert engageable into the outer anchor sleeve and having an outer end for being driven by a tool, and a penetrating element attached to the insert to drill and move the anchor sleeve into the wall, the outer anchor sleeve may be expanded and engaged with the work piece, and the penetrating element includes one or more projections for centering the penetrating element relative to the work piece and for preventing the penetrating element from being tilted relative to the work piece. | 11-27-2008 |
20090074533 | Self-drilling anchor - A self-drilling anchor is provided which includes an elongated tapered plastic body and anchor assembly. The body has an external helical threaded portion, a central clear bore for receiving the anchoring assembly, two diametrically opposed break-away slotted portions, and an axial driving flange concentrically positioned relative to the tapered body first end. The flange has inner and outer walls, a central clear aperture for receiving a screw driver, and at least two diametrically opposed notches for receiving a bladed driver for drilling the tapered body into a hollow wall. The anchoring assembly is centrally received in the clear bore, and includes an externally threaded screw, a collar, and at least two diametrically opposed separable arms. The collar is internally threaded for receiving the screw. The separable arms have spring loaded ends and pointed ends. The spring loaded ends are pivotally attached to the collar. The pointed ends of the separable arms form a disconnected pointed drilling tip when pivoted in a collapsed orientation, and an anchor supporting orientation when operated for separation, by rotation of the screw, through the break away slotted portions, for engagement of the separable arms with an inner surface of the hollow wall to be anchored. | 03-19-2009 |
