Definitions

  • the present invention relates to an improved safety harness restraining fixture.
  • the safety harness restraining fixture covered by this invention is simple in design and is applicable for use with all kinds of scaffolding, structures and suchlike, since it embodies a restrainer piece which is able to travel freely along a counterweighted rope or cable when there is no undue strain and accordingly no accident risk.
  • Said restrainer piece is also connected to a rope or cable to hold the person, but with an intermediate shock absorber assembly arranged so that in the event of operating, there is a sharp pull applied between the restrainer piece and the counterweighted rope, but not between this restrainer piece and the person who is held, and the safety harness becomes secured at a particular position on the counterweighted rope, and prevents the person from falling.
  • the improved safety harness restraining fixture is basically made up from the following components:
  • Restrainer piece (1) is capable of travelling along or becoming engaged upon a rope or cable (3)which is counterweighted at one of its ends (4), and secured at the other to the structure being built, the scaffolding or similar (5), whilst in a different area, said restrainer piece (1) is linked in space to the shock absorbing assembly (2), by means of which it secures the body of workman, likewise by means of rope or cable. See Figure 1.
  • restrainer piece (1) is capable of sliding along or becoming engaged upon a rope or cable (3) that is counterweighted at one of its ends (4), and secured at the other to the shock absorbing assembly (2), by means of which it is attached to the structure being built, the scaffolding or similar (5).
  • the restrainer piece (1) is linked, likewise by means of rope or cable, to the body or workman
  • the restrainer piece (1) possesses, in accordance with a practical construction thereof, a general asymmetrical "U" shape whose curved web is provided with a hole (11), whilst its lugs (12 and 13) each have enlargements (120 and 130 respectively) on their ends, and which enlargements are each provided with a hole (121 and 131 respectively) going through same, the width of which varies evenly and where one such hole (121) is located the other way about from the other (131).
  • the shock absorbing assembly (2) as illustrated in the practical construction depicted by Figure 5 is comprised of two pins, of which one is straight (20), and the other is "U" shaped (21), these being assembled upon a plate (25) in such a manner that pin (20) can travel and pin (21) is stationary.
  • Such attachment is accomplished by means of two sets of nuts (24), each screwed onto one of the threaded portions (211) of pin (21) securing same at either side of plate (25).
  • the straight pin (20) goes through a hole (251) located in the centre of the plate, and at one of its ends there is a lug provided with a hole (201), while at the other there is a threaded length (202), where in the former a cable or rope is placed to secure the person or workman, while upon the latter there is a nut (23) that holds a stop washer, between which stop washer and plate (25), a dampener spring (22) is fitted.
  • the freely swivelling linkage between the restrainer piece (1) and the shock absorbing assembly (2) is accomplished in this practical construction of the invention with a washer (6) placed in the hole (11) on the restrainer piece (1) and linked in turn to pin (21) in the shock absorbing assembly (2).
  • the shock absorbing assembly (2') illustrated in Figure 7 is comprised of two pins, of which one is straight (20') and the other shaped in the form of a "U" (21'), the tips of whose arms (25') are bent outwards in order to make a stop.
  • Pin (21') is fitted with a washer (26') that has holes at its centre and across its diameter which accommodate pins (21') and (20') respectively, this latter being secured with a nut (23') that holds a stop washer (26'), between which stop washer and bent tips (25'), a dampening spring (22') is fitted.
  • the freely swivelling linkage between the rope (3) and the shock absorbing assembly (2') is accomplished in this practical construction of the invention by means of threading said rope (3) through a hole (201') that is provided on the end of pin (20'). Said shock absorbing assembly (2') is then secured to the structure or scaffolding (5) by means of a ring (6).
  • the rope or cable (3) counterweighted at (4) and secured to the structure or scaffolding (5) is threaded through holes (121 and (131) in their wide sections, so that free travel is afforded in the direction shown by the counterweighted rope (3).
