Furthermore, such systems often include a soft sided bag for containing at least a safety cord, but the bag does not necessarily facilitate easy use during an emergency
Therefore, there is always room for improvement and especially for solving the above-mentioned problems

Embodiment Construction

[0024] refer to figure 1 with 2 , provides a descent system 10 for use with a rescue descent device (RDD) 12 to allow a user to safely descend from an elevated structure such as a high floor in a building, a drilling platform, a windmill platform or a utility tower. Although shown in a particular configuration, RDD 12 may be any suitable rescue or controlled descent device, many of which are known, one sold by Honeywell under the Miller SafEscape™ ELITE trademark, another example by DBI / Sala is sold under the trademark Rescuematic® Automatic Descent Controller.

[0025] Descending system 10 includes a safety line reel 14 for receiving a length of safety line 16 wrapped around reel 14 in a ready-to-deploy condition. Safety line reel 14 is mounted to rigid frame 20 for rotation about axis 22 to allow the length of safety line 16 to be unwound from reel 14 to RDD 12 as RDD 12 provides a controlled descent to a user tethered to safety line 16 . System 10 also includes a frict...

Abstract

The present invention provides a descent system including a safety rope reel for use with a rescue descent device, and more particularly provides a descent system for use with a rescue descent device (RDD) that allows a user to safely descend from an elevated structure, And it includes a safety line reel for receiving a length of safety line wrapped around the reel in a ready-to-deploy condition. The safety line reel is mounted to the rigid frame for rotation about an axis to allow the length of safety line to be unwound from the reel to the RDD as the RDD provides a controlled descent to a user tethered to the safety line. The system also includes a friction mechanism mounted to the rigid frame and engaged with at least one of the cord and the reel to generate a frictional load as the safety cord is unwound to the RDD to allow the safety cord to be unwound from the reel to the RDD in a controlled manner. RDD.

Description

technical field [0001] The present invention relates to a system utilizing a rescue descent device, also known as a controlled descent device, for emergency rescue to allow a user to safely descend from an elevated structure, the rescue descent device being configured to automatically apply force to a safety rope To provide a controlled descent of a user tethered to the safety line as the safety line passes through the descending device. Background technique [0002] One problem with conventional rescue descent systems of this type is that the relatively long and heavy length of safety line must first be cast from the user's position on an elevated structure, such as a tall building or tower, and the pair of falling safety lines located at People below the user's position pose a danger. This is particularly problematic in emergency situations such as fires where there could potentially be multiple deployments of Rescue Descent Devices (RDDs) within a very short period of ti...
