Abstract
A retaining device is disclosed for attaching a chainsaw to a worker, working aloft. The retaining device provides a tear-away component between two sections of a lanyard. When the chainsaw is pinched in a falling limb, the slow, tearing motion of the tear-away component results in a minimal amount of impact force being exerted on a worker. In the event the tear-away component pulls apart entirely, the chainsaw is released from the worker and falls to the ground with the limb. The worker maintains his/her position within the structure. Alternatively, if the chainsaw is dropped by the worker, it will fall below the feet of the worker, allowing him/her to retrieve the chainsaw. A bystander below will not be hit by the falling chainsaw.
Claims17
A retaining device for attaching a mechanical tool or apparatus to a worker, said retaining device comprising:
- a first lanyard section having a distal end and a proximal end, said proximal end thereof having connection means for connecting to a worker;
- a second lanyard section having a distal end and a proximal end, said distal end thereof having attachment means for attaching to a mechanical device, said second lanyard section including a stretchable component comprising an elastic cord disposed within a hollow strap and said elastic cord being free to move within said hollow strap;
- and
- a separating and tear-away component intermediate said first and second lanyard sections, one end of said separating and tear-away component being fixedly attached to said distal end of said first lanyard section and the other end of said tear-away component being fixedly attached to said proximal end of said second lanyard section, said separating and tear-away component having means to gradually separate and tear, so that, when said first and second lanyard sections are caused to separate from each other, said tear-away component minimizes the force induced on the worker, reducing the potential of injury to the worker.
A retaining device for attaching a mechanical tool or apparatus to a worker, said retaining device comprising:
- a lanyard section having a distal end and a proximal end, said distal end thereof having connection means for connecting to a tool, said lanyard section including a stretchable component comprising an elastic cord disposed within a hollow strap and said elastic cord being free to move within said hollow strap;
- and
- a separating and tear-away component operatively connected to said proximal end of said lanyard section, said separating and tear away component having attachment means connected thereto for attaching said retaining device to a worker, said separating and tear-away component having means to gradually separate and tear, so that, when said worker and said at least one lanyard section are caused to separate from each other, said separating and tear-away component minimizes the shock of said separation, reducing the potential of injury to the worker.
