Title:
輪郭ブレーキ手段を有するスイベルアームを備えた下降装置
Document Type and Number:
Japanese Patent JP3176021
Kind Code:
U
Abstract:
The present invention relates to a lowering device (1), comprising a base part (2), a handle (3), a lifeline (4) and an attachment (7) for a rescue harness or a safety belt, wherein the base part (2) and the handle (3) are fixedly connected to each other, wherein the base part (2) comprises a first deflecting means (5) and a second deflecting means (6), that said first deflecting means (5) also constitutes a braking means located adjacent to an outlet opening (10) for the lifeline (4), that a first, incoming portion (4a) of the lifeline is adapted to run around said first deflecting means (5) while bearing against a contact surface (A) of said first deflecting means, that a second, outgoing portion (4b) of the lifeline is adapted to run around said second deflecting means (6) and further out through the outlet opening (10) while when under load it abuts in frictional engagement against the first, incoming portion (4a) of the lifeline along at least part of the length where the first lifeline bears against said contact surface (A), that a fulcrum (M) is formed in an abutment region between the two portions (4a, 4b) of the lifeline and the contact surface (A), that the handle (3) and the attachment (7) are positioned on either side of the first deflecting means (5) and adapted to rotate the base part (2) in a common rotational plane (P) about this fulcrum (M), that the attachment (7) comprises a swivel arm which is rotatably connected to the base part (2) on a pivot point (8) for rotation of the swivel arm in said rotational plane (P) and an attachment means (11) for said rescue harness or safety belt, wherein the swivel arm is designed to be brought into engagement with said second portion (4b) of the lifeline in the abutment region between the two portions (4a, 4b) of the lifeline and the contact surface (A) for producing a compressive force (F) against the lifeline, whereby the abutment contact between the two portions of the lifeline, and thereby the frictional force, can be increased.
