Patent application number | Description | Published |
20090078505 | Safety device - A safety device includes a locking mechanism connected to a first portion and a braking mechanism connected to a second portion. The locking mechanism includes at least one pawl and a biasing member urging the at least one pawl into an engaging position. The braking mechanism includes at least one tooth having an engaging surface, and the at least one pawl engages the engaging surface in the engaging position. The engaging position prevents rotation of the first portion in the first direction and allows rotation of the first portion in the second direction. A force of at least 250 pounds on the first portion allows the braking mechanism to rotate thereby allowing the first portion to rotate in the first direction. The braking mechanism is prevented from rotating when the force has been released from the first portion thereby preventing rotation of the first portion in the first direction. | 03-26-2009 |

20110094839 | ENERGY ABSORBER - An energy absorber comprises an intermediate portion interconnecting a first end and a second end. The intermediate portion and the first and second ends are on the same plane. The intermediate portion includes curved portions configured and arranged to deform and begin to straighten when subjected to a pre-determined load to absorb energy from the pre-determined load. Should a user fall, the energy absorber will deform (begin to straighten) to absorb energy from the fall. Optional pins prevent material from getting caught in the energy absorber, assist in stiffening the energy absorber, and assist in pre-stressing the energy absorber so that it will not open up when subjected to a load less than the pre-determined load. Optional tabs and slots or protrusions and notches prevent material from getting caught in the energy absorber. | 04-28-2011 |
