Descent control device
First Claim
1. A descent control device for use with a rope, comprising:
- a frame comprising;
a first end, a second end, a first opening, a second opening, a third opening, and an internal cavity connecting said first opening, said second opening and said third opening, wherein said first opening and said second opening form a channel having a width and extending along a generally horizontal axis in a direction from said first opening to said second opening, said channel being adapted for receiving a rope;
a grip positioned between said second opening and said third opening in proximity to said second end of said frame, said grip extending away from said frame along a generally vertical axis; and
a means for attaching the descent control device to a user, wherein said means for attaching is in proximity to said first end of said frame generally across from said second opening near the horizontal axis through which said channel extends;
a handle rotatably mounted to said frame within said internal cavity and having a first end that extends from said frame in a direction generally parallel to the direction in which said grip extends, and a second end that forms an upper boundary to the channel formed by said first opening and said second opening such that said second end of said handle is adapted for modifying the width of said channel upon rotation of said first end of said handle; and
a cover pivotally mounted to said frame for maintaining the rope in said channel.

Abstract
A descent control device for use with a rope for controlling a user'"'"'s rate of descent down the rope. The device has a frame with a grip, three openings and an internal cavity connecting the openings, wherein two openings form a channel extending along a generally horizontal axis. The grip extends away from the frame along a generally vertical axis. A handle is rotatably mounted to the frame within the internal cavity and extends away from the frame in a direction generally parallel to the grip. One end of the handle is preferably Y-shaped and forms an upper boundary to the channel such that the end of the handle is adapted for modifying the width of the channel upon rotation of the handle. A cover is pivotally mounted to the frame for maintaining the rope in the channel.

16. A method for descending down a rope, comprising the steps of:
-
(a) securing the rope to an anchor point;
(b) threading the rope through a descent control device comprising;
a frame comprising;
a first end, a second end, a first opening, a second opening, a third opening, and an internal cavity connecting said first opening, said second opening and said third opening, wherein said first opening and said second opening form a channel having a width and extending along a generally horizontal axis in a direction from said first opening to said second opening, said channel being adapted for receiving a rope;
a grip positioned between said second opening and said third opening in proximity to said second end of said frame, said grip extending away from said frame along a generally vertical axis; and
a means for attaching the descent control device to a user, wherein said means for attaching is in proximity to said first end of said frame generally across from said second opening near the horizontal axis through which said channel extends;
a handle rotatably mounted to said frame within said internal cavity and having a first end that extends from said frame in a direction generally parallel to the direction in which said grip extends, and a second end that forms an upper boundary to the channel formed by said first opening and said second opening such that said second end of said handle is adapted for modifying the width of said channel upon rotation of said first end of said handle; and
a cover pivotally mounted to said frame for maintaining the rope in said channel;
(c) attaching the descent control device to a user; and
(d) controlling how fast the user descends down the rope by rotating the handle of the descent control device. - View Dependent Claims (17, 18, 19)
