Abstract
A toggle bolt capable without disassembly or reassembly of cutting a mounting hole through a wall and being easily installed therein. The toggle bolt includes a generally tubular sleeve having an internally threaded collar pivotally mounted at a position along the longitudinal axis of the sleeve such that the sleeve includes a heavier portion between the collar and one end and a lighter portion between the collar and the opposite end. One of the sleeve ends has cutting teeth or other cutting configuration, and a slot is provided in the wall of the sleeve along the lighter portion thereof. A bolt is threaded into the collar and is disposable transversely of the sleeve during drilling of a mounting hole and is disposable via the slot coaxially of the sleeve for insertion of the sleeve through the mounting hole for anchoring therein.
Claims6
A toggle bolt comprising:
- a generally tubular sleeve having on an end thereof a toothed cutting configuration suitable for cutting a circular opening through a wall to which the toggle bolt is to be mounted;
- an internally threaded collar pivotally mounted in said sleeve at a position along the longitudinal axis of the sleeve providing a heavier portion between said collar and one end and a lighter portion between said collar and the opposite end of said sleeve;
- a slot provided in the wall of said sleeve extending longitudinally between said collar and said opposite end;
- a threaded bolt threadably mated with the collar and having a diameter less than the width of the slot and operative to pass through said slot into longitudinal generally coaxial alignment with said sleeve;
- and
- an opening through the wall of said sleeve confronting said collar permitting threading of said bolt through said collar and passage through said opening into generally transverse position with respect to the longitudinal axis of said sleeve;
- said threaded bolt being operative in a first position with the bolt extending transversely through the sleeve to provide first and second outwardly extending handles for manual rotation or reciprocation of said sleeve to cause said cutting configuration to cut a circular mounting opening through a wall, and after cutting of the mounting opening by said cutting configuration to be threaded out of said sleeve wall opening and pivoted through said slot into a second position in longitudinal generally coaxial alignment with said sleeve and operative to push said sleeve through the mounting opening in said wall.
