Abstract (en)
[origin: US5481943A] A safety device used in case of rupture of a rotary shaft for preventing the shaft from rotating and for preventing broken portions thereof from falling, includes at least one safety element placed so as to retain the shaft to prevent it from falling. The peripheral surface of the shaft and a facing surface of the safety element are provided with mating devices that cooperate to prevent the shaft from rotating when a portion of the shaft is retained by said safety element due to the shaft rupturing. The device is particularly suitable for use with a shaft that winds up lifting straps for a raisable curtain or that winds up the curtain itself.
