Abstract
A fall detection/fall indicator device (20) that automatically senses when a user (14) of fall protection equipment, such as a fall harness (10), has experienced an arrested fall, the fall harness (10) having an electrical circuit (45) that is a closed circuit (46) in a first state and an open circuit (48) in a second state after an arrested fall, and an alert device (62) that is automatically responsive to the open circuit (48) to emit an alert/alarm to other personnel that an arrested fall has been experienced.
Claims25
A harness for arresting a user's fall, the harness comprising:
- a length of strap configured to secure the harness to a securing point
- a first electrical contact mounted on a first portion of the length of strap and a second electrical contact mounted on a second portion of the length of strap adjacent the first portion such that, when the harness is in a first configuration, the first electrical contact is electrically coupled to the second electrical contact to form a closed circuit and the length of the strap is in folded configuration, and, when the harness is in a second configuration, the first electrical contact is electrically decoupled from the second electrical contact to form an open circuit and the length of the strap is in unfolded configuration;
- and
- an alert device operably connected to the first electrical contact and second electrical contact and configured to provide an alert when the harness is transitioned from the first configuration to the second configuration.
A harness for arresting a user's fall, the harness comprising:
- a length of strap configured to secure the harness to a securing point
- a first electrical contact supported on a first portion of the length of strap and a second electrical contact supported on a second portion of the length of strap such that, in the first configuration, the first electrical contact is electrically coupled to the second electrical contact through an electrical coupling to form a closed circuit and, in the second configuration, the first electrical contact is electrically decoupled from the second electrical contact to form an open circuit;
- and
- an alert device operably connected to the first electrical contact and second electrical contact and configured to provide an alert when the harness is in one of the first configuration and the second configuration.
A harness for arresting a user's fall, the harness comprising:
- a length of strap configured to transition from a first conformation to a second conformation;
- a first electrical contact and a second electrical contact supported on the length of strap such that, in the first conformation, the first and second electrical contacts form a closed circuit and, in the second conformation, the first and second electrical contacts are electrically decoupled to form an open circuit;
- and
- an alert device operably connected to at least one of the first or second electrical contacts and configured to provide an alert when the length of strap is transitioned from the first conformation to the second conformation.
