Abstract
A ladder climbing safety clamp is claimed that may be easily operated by a worker with one hand while overcoming many potential safety hazards of prior devices. The safety clamp includes a body with a U-shaped cable sleeve. A channel is included on one side of the body to permit the introduction of the safety line in the cable sleeve. However, if the cable is too large to operate properly with the safety clamp, it will not fit through the channel, thereby helping to prevent inadvertent usage of the safety clamp with a cable of a diameter for which it is not intended. A gravity stop is also provided to prevent the safety clamp from being inadvertently installed in an upside-down position, since the safety clamp would not operate correctly in that position.
Claims16
A safety device adapted to be secured to a person working at an elevated level and having means to releasably engage an elongated safety carrier, such as a cable or rod, if the person falls, comprising:
- a housing having a first side and a second side;
- a sleeve fixed to said second side of said housing, whereby the elongated safety carrier to which the safety device is engaged passes through said sleeve;
- an arm protruding from and pivotally linked to said housing;
- a shoe, pivotally linked to said arm, for frictionally engaging the elongated safety carrier;
- a channel in said first side of said housing for receiving the elongated safety carrier within said sleeve;
- a lock pivotally attached to said housing for restricting the range of motion of said show, said lock being pivotable between a locked position and an unlocked position;
- and
- biasing means for biasing said lock to said locked position.
A safety device adapted to be secured to a person working at an elevated level and having means to releasably engage on elongated safety carrier, such as a cable or rod, if the person falls, comprising:
- a housing having a channel through a sidewall thereof for slidably receiving the elongated safety carrier;
- means for linking said housing to the person;
- means for releasably engaging the safety device in a fixed position relative to the elongated safety carrier;
- and
- means for restricting the range of motion of said means for releasably engaging the safety device movable between a locking position and an unlocking position;
- and
- means for biasing said motion restricting means to said locking position.
A safety device adapted to be secured to a person working at an elevated level and having means to releasably engage an elongated safety carrier, such as a cable or rod, if the person falls, comprising:
- a housing having a first side and a second side;
- a sleeve fixed to said second side of said housing, whereby the elongated safety carrier to which the safety device is engaged passes through said sleeve;
- an arm protruding from and pivotally linked to said housing;
- a shoe, pivotally linked to said arm, for frictionally engaging the elongated safety carrier;
- and
- means for preventing the safety device from being positioned upside down on the elongated safety carrier.
A safety device adapted to be secured to a person working at an elevated level and having means to releasably engage an elongated safety carrier, such as a cable or rod, if the person falls, comprising:
- a housing for slidably receiving the elongated safety carrier;
- means for linking said housing to the person;
- means for releasably engaging the safety device in a fixed position relative to the elongated safety carrier;
- and
- means for preventing the safety device from being positioned upside down on the elongated safety carrier.
