DESCRIPTION
[0015] The present invention provides a different embodiment of the
disclosure of U.S. Pat. No. 6,899,203 issued on 31 May 2005 to
Golden et al., which patent is incorporated herein by reference.
This embodiment provides a more controlled release during operation
of the rope control apparatus.
[0016] FIG. 1 is an exploded diagram illustrating the manner in
which the components of the prior art rope management device of
U.S. Pat. No. 6,899,203 are assembled in relationship to each
other.
[0017] FIG. 2 is an exploded diagram illustrating the manner in
which components of the present invention are assembled in
relationship to each other in accordance with the present
invention. As illustrated, the major components include upper brake
30, lower brake 31, sideplates 60, 61, 80 and 81, handle 5a,
bushing 4a, 6a and 8b, roller disc 6c, bolt 8d with push pin 9b,
locknuts 7b, 7b' and 8c, washers 9b and 9b' and connective bolts 6b
and 6b'.
[0018] As indicated in FIG. 2 the components of the invention are
variously assembled as follows:
[0019] a first brake 30 has a first pivot hole 30a, a second pivot
hole 30b, and an attachment hole 3a configured to be linked to an
end of a rope;
[0020] a second brake 31 having a third pivot hole 31a and a fourth
pivot hole 31b;
[0021] a first sideplate 80 rotatably affixed at fifth hole 80a to
a first side of the brake 30 at the first pivot hole 30a by means
of bolt 6b and rotatably affixed at 8a to a first side of the brake
31 at a third pivot hole 31a by means of bushing 8b;
[0022] a second sideplate 81 rotatably affixed at a sixth hole 81a
to a first side of the brake 31 at the fourth pivot hole 31b and
rotatably affixed at 8c to a first side of the brake 30 at the
second pivot hole 30b by means of bolt/pin 8d;
[0023] a third sideplate 60 rotatably affixed at seventh hole 60a
to a second side of brake 31 at the fourth hole 31b by means of
bolt 6b' and to a second side of brake 30 at second hole 30b by
means of bolt 8d, bolt 8d continuing on through eighth hole 60b of
third sideplate 60 to terminate with lockwasher 8c;
[0024] a fourth sideplate 61 rotatably affixed at ninth hole 61b to
the second side of the brake 30 at the first hole 30a by means of
bolt 6b and rotatably affixed tenth hole 61c by means of a portion
of bolt 8d to the second side of the brake 31 at the third hole
31a;
[0025] roller disc 6c connected by means of bolt 6b through washer
9b and hole 61b;
[0026] handle 5a connected by means of bolt 6b' through washer 9b'
and hole 5b to seventh hole 60a of sideplate 60 and positioned to
cam off roller disc 6c; and
[0027] bushing 4a, which aids in the ascent mode when the operator
is pulling a rope through the apparatus of the invention, is
positioned between sideplates 61 and 80 and connected at eleventh
hole 61a to sideplate 61.
[0028] Bolt 8d has push pin 9b connected and positioned to aid in
providing braking pressure to the rope.
[0029] FIGS. 3A-3E are plan view diagrams illustrating various
components of the rope control device according to the present
invention. It is to be noted that the configurations of the
components may be somewhat different in the various views, however,
the function of the component is as described. FIG. 3A illustrates
upper brake 30 having attachment point hole 3a, hole 30b for
receiving bolt 8d therethrough, and first pivot hole 30a.
[0030] FIGS. 3B-3D illustrate attachment point hole 3a with various
positions of the side plates 80, 81 and 61. FIG. 3B shows the
attachment point 3a with the apparatus in the full open state with
the sideplates 80, 81 in the open view. Indicated in dotted lines
is the manner in which the rope passes under sideplates 80 and 81
and between brakes 30 and 31. Also indicated is the user attachment
point 3a, the user attached by carabiner. A second carabiner
attachment point is indicated as attached to sideplate 31 at hole
31a. FIG. 3C shows the attachment point 3a with the apparatus in
the full open position with the sideplates 80, 81 in the closed
position. FIG. 3D shows the attachment point 3a with the apparatus
in the full closed position with the sideplates 80, 81 in the
closed position.
[0031] FIGS. 4A and 4B illustrate ascender aid bushing 4a, FIG. 4A
showing sideplate 61 having bushing 4a connected as described above
in a manner to aid in providing easier accent of the user. FIG. 4B
illustrates bushing 4a with the rope control apparatus in the full
open position.
[0032] FIGS. 5A-5C illustrates cooperation of the handle 5a and the
roller/disc 6c to cam sideplates 60 and 61. FIG. 5A shows an
example configuration of the handle 5a with FIG. 5B illustrating
handle 5a in the full open position and FIG. 5C illustrating handle
5a in the full closed position. As shown in FIG. 2 handle 5a is
attached by a bolt 6b' through hole 5b of handle 5a and through
hole 60a of sideplate 60, and thence on through hole 31b of brake
31 and hole 81a of sideplate 81 to terminate in a lock washer.
Handle 5a is thus able to cam off of the bolt 6b' using roller/disc
6c, which allows variation of pressure on the rope by brakes 30 and
31 to thereby control the force needed to release bite on the rope.
This also allows for varied rope sizes. This arrangement, in
combination with the attachment point 3a provides for more
controlled release when descending.
[0033] FIGS. 6A-6C illustrate in exploded views (FIGS. 6A and 6B)
and in assembled plan view (FIG. 6C) a pair of bushings 6a that are
spacers and act as bearings both for handle 5a and roller/disc
6c.
[0034] Even though the handle 5a of FIG. 5A-5C is shown in FIG. 2
and described above, FIGS. 7A and 7B is illustrative of a
combination handle 7a and roller disc 7b embodiment that is also
exemplary of the present invention. Shown in FIG. 7A with the
apparatus of the invention in open view is the handle 7a and
roller/disk 7b positioned and cooperating to cam affixed
sideplates. As arranged, the handle 7a is able to cam in a manner
to increase or decrease bite on a portion of the rope thereby
providing controllable force to release clamping force on the rope,
and as well handle varied rope sizes. FIG. 7B illustrates the
handle 7a and roller/disk 7b with the apparatus in closed
position.
[0035] FIGS. 8A-8D illustrate channeled and slotted sideplates with
machined on washers. FIG. 8A illustrates sideplate 80 having
channel 8a for receiving non-attached bushing 8b with machined on
washers 8e and 8f. FIG. 8B illustrates captivated bushing 8b. FIG.
8C illustrates sideplate 81 having channel 8c for receiving
non-attached bolt/pin 8d and FIG. 8D illustrates attached bolt/pin
8d.
[0036] FIGS. 9A and 9B illustrate bolt 8d which includes push pin
9b and spring 9c, FIG. 9A being an exploded view showing assembly
of the components and FIG. 9B showing the components assembled.
Also shown in FIG. 9A is sideplate 81 having hole 9e for admitting
push pin 9a to protrude therethrough.
[0037] Although the present invention has been described with
reference to illustrated and described embodiments, other
modifications and embodiments can be devised by those skilled in
the art that that would fall within the spirit and scope of the
invention.
