Description
BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to a cord protector, and more
particularly to a cord protector capable of preventing collision
between combined rigid components to protect combined rigid
components and operating users, thereby increasing use safety.
Description of the Related Art
[0002] A "cord" is a kind of rope that can be resisted with pull
force, and the material of the cord is diversity. To pull heavy
weight early, the cord can be made of using steel wire and is so
called steel cable. Recently, applied chemistry is well developed,
and synthetic resin material resisting pull has been developed. The
material is applied to produce the cord for replacing the steel
cable. The cord made of using synthetic resin is normally called as
the synthetic cable having advantage of steel cable (pull
resistance) without defect of steel cable (including lightweight,
difficult wounding while swinging). This cord is gradually paid
attention and adopted. In the disclosure, the material of the
"cord" can, but not limited to, be steel cable, synthetic cable,
etc.
[0003] The obvious instance of using the cord is "power winch". The
"power winch" is a hoist power appliance of hoisting or laying down
heavy weights and also called as "hoist machine". Places of
mounting the power winch include high storied buildings' heavy
goods vertical lifting or jeeps, all-terrain vehicles that drag
other vehicles or self-help moving (out of danger).
[0004] There are two types of disposing the cord on the power
winch. The first type is shown in FIG. 1, a side is disposed with a
power source 11 (a motor for example), and its generated power is
transmitted by internal shaft core to drive a deceleration device
12 disposed at side neighbor or another side. The deceleration
device 12 drives a cable pulley 13 for rotating after undergoing
several levels of deceleration (planetary gear set for example) and
transmission effect so that the cord 14 wound on the cable pulley
13 can perform motion of positive rotation discharging or counter
revolution retracting. The cord 14 can be released or retracted
through a discharging hole 151 on a discharging seat 15. The
innermost end head of the cord 14 is combined with the cable pulley
13. When the cable pulley 13 rotates, the cord 14 can be wound on
the cable pulley 13. The outermost end head of the cord 14 is
stretched out of the discharging hole 151 of the discharging seat
15 and passes through a joining perforation 161 at a tail of a hook
head 16 by way of fixedly connecting a collar 17 so that the hook
head 16 locates at the front end of the cord 14. Therefore, while
hoisting, the cord 14 is continuously stretched out of the
discharging hole 151, and the hook head 16 at the front end
executes hooking motion.
[0005] A second type is shown in FIG. 2, it still provides power
through a power source 11, and a deceleration device 12 is driven
through internal transmission and further drives a cable pulley 13
for rotating through several series of slow down to allow the cord
14 wound on the cable pulley 13 to perform motion of positive
rotation discharging or counter rotation retracting. After the
outermost end head of the cord 14 also passes through a joining
perforation 161 at a tail end of a hook head 16, it is fixedly
connected by a collar 17. The difference between the second type
(shown in FIG. 2) and the first type (shown in FIG. 1) is that the
cord 14 in the second type is discharged or retracted by the
discharging hole 181 at the middle of a four-way roller set 18.
[0006] As shown in FIGS. 1, 2, the cord 14 can be stretched from
the discharging hole 151 of the discharging seat 15 and can be
stretched from the discharging hole 181 at the middle of the
four-way roller set 18. Assembling the discharging seat 15 or the
four-way roller set 18 on the power winch depends upon
manufactures.
[0007] To look for rigidity, the discharging seat 15 or the
four-way roller set 18 is made of metal material. For the same
reason, the hook head 16 must also have rigidity since it is used
for hoisting heavyweights. Therefore, the hook head 16 is also made
of metal material. The cord 15 must resist pull to have flexibility
and bending resistance. The cord 14 may be discharged by power
while stretching out. The cord may also be pulled by labor force
after turning off power. No matter the cord 14 is discharged by any
force, collision or impact phenomenon basically may not occur to
have extremely low risk. When the cord 14 is retracted on the cable
pulley 13 of the power winch, it must be pulled back at certain
speed through power. Finally, when the hook head 16 collide the
discharging seat 15 or the four-way roller set 18, power then is
stopped after sensing through upper limit switch or pressure switch
inside the machine. In a motion of retracting the cord 14, the hook
head 16 collides the discharging seat 15 or the four-way roller set
18 is taken for granted. In another word, collision is necessary to
completely retract the cord 14.
[0008] Based upon the inventor of the present invention conducting
researches and experiences in power winch for many years, the hook
head 16 colliding the discharging seat 15 or the four-way roller
set 18 has the following shortcomings:
1. Each rigidity impact between the hook head 16 ad the discharging
seat 15 or between the hook head 16 and the four-way roller set 18
certainly has damage inside both or on the surface. While reaching
a critical point, minor impact any one of the hook head 16, the
discharging seat 15 or the four-way roller set 18 is damaged or
broken to replace, and major impact industrial safety issue, such
as load shedding, may occur due to damage of the hook head 16. In
addition, any part may be damaged or fall to harm persons. The
foregoing accident may instantly happen and is difficult to take
action in early stage in advance. 2. The direct contact between the
hook head 16 and the discharging seat 15 or between the hook head
16 and the four-way roller set 18 regarding the power winch
disposed on the vehicle frequently generates continuous noise of
"kluck-kluck-kluck", thus affecting emotion of persons in vehicle
to generate tense and restlessness. It does not only influence
physical and mental health but also causes accidents. The frequent
rigid collision between the hook head 16 and the discharging seat
15 or between the hook head 16 and the four-way roller set 18 will
affect each component's completeness of the power winch.
Consequently, the mesh of internal gears of the power source 11
and/or the deceleration device 12 is sometimes not correct.
Sometimes, the accuracy of the brake may be affected. The cord 14
sometimes may loose or assembling among components is not
tight.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0029] The technical characteristics, contents, advantages and
effects of the present invention will be apparent with the detailed
description of a preferred embodiment accompanied with related
drawings as follows.
[0030] With reference to FIGS. 3-7 for a cord protector 2 according
to the embodiment of the present invention, the structure is formed
by co-assembling a first protection seat 21 and a second protection
seat 22, and the first protection seat 21 and the second protection
seat 22 are made of a flexible material that resists impact, such
as synthetic rubber, rubber doped with synthetic resin, etc.,
wherein an external side surface of the first protection seat 21 is
a circle arc cone having narrow front and wide rear condition while
inner side is a flattened shape. A bottom of the flattened inner
side is an opening 211. Two end inner sides of the opening 211 are
respectively recessed to form a joining cavity 212. The opening 211
is extended toward the top portion and enlarged and, while reaching
the top portion, divided by a cross bar 213 to form two through
grooves 214. The lateral cross-section of the cross bar 213 is a
triangular pyramid having narrow inside and wide outside condition.
An arc groove 215 obliquely disposed is formed on the inner side
wall of each through groove 214. Two ends at the flattened inner
side are respectively opened with a joining through groove 216
communicating toward outside.
[0031] An external side surface of the second protection seat 22 is
also a circle arc cone having narrow front and wide rear condition
while an inner side is also a flattened shape. A bottom of the
flattened inner side is an opening 221. Two end inner sides of the
opening 221 are respectively protruded to form joining protrusions
222. The opening 221 is formed with a set of arc grooves 225
obliquely disposed on the wall surface of the flattened inner side
after extending a small section toward the top portion. Two ends of
the flattened inner side are respectively disposed with a joining
through groove 226 communicating toward the outside, wherein the
opening 221 of the second protection seat 22 corresponds to the
opening 211 of the first protection seat 21. The position and size
of the joining protrusion 222 of the second protection seat 22
corresponds to the joining cavity 212 of the first protection seat
21. The arc groove 225 of the second protection seat 22 is
symmetric with the arc groove 215 of the first protection seat 21
by spacing an interval. The joining through groove 226 of the
second protection seat 22 corresponds to the joining through groove
216 of the first protection seat 21.
[0032] While in assembling, the flattened inner side of the second
protection seat 22 is pasted to the flattened inner side of the
first protection seat 21 to co-form a circle cone body having
narrow front and wide rear condition as shown in FIGS. 5, 6, 7. In
the process, the joining protrusion 222 of the second protection
seat 22, one by one exactly enters in the joining cavity 212 of the
first protection seat 21 for stay, and a circle opening is formed
by co-surrounding the opening 221 of the second protection seat 22
and the opening 211 of the first protection seat 21 as shown in
FIG. 6. At the same time, the cross bar 213 of the first protection
seat 21 exactly leans against the flattened inner side of the
second protection seat 22 as shown in FIG. 5. Moreover, the joining
through groove 216 of the first protection seat 21 correspondingly
penetrates through the joining through groove 226 of the second
protection seat 22. Accordingly, a set of male joining members 23
(screws for example) is joined with a set of female joining members
231 (nuts for example) after passing through the joining through
grooves 226, 216 so that the first protection seat 21 and the
second protection seat 22 are assembled to form a completely cord
protector 2.
[0033] The cord protector 2 is specifically designed to combine
with a cord 14 and to protect the cord 14. With reference to FIGS.
8, 9, before the cord protector 2 is not joined with the female
joining members 231 (nuts for examples) through the male joining
members 23 (screws for example), the collar 17 outside the cord 14
can be co-clamped by the opening 211 of the first protection seat
21 and the opening 221 of the second protection seat 22. The
outermost end head of the cord 14 revolves to fasten the cord 14
through the collar 17 after normally passing through a joining
perforation 161 at the tail end of a hook head 16, and the hook
head 16 is located at the front end of the cord 14. Accordingly,
the opening 211 of the first protection seat 21 and the opening 221
of the second protection seat 22 exactly co-clamp the collar 17. At
the same time, the cross bar 213 of the first protection seat 21
passes through a revolving combination place of the cord 14 so that
cord bodies of the cord 14 at two sides respectively enter in the
two through grooves 214 of the first protection seat 21 for stay
after revolving. If the cord body of the cord 14 is in larger wide
condition, it is co-supported and clamped by the arc groove 215 of
the first protection seat 21 and the arc groove 225 of the second
protection seat 22. After completing the motion of co-clamping the
collar 17 through the first protection seat 21 and the second
protection seat 22 and enabling the cross bar 213 of the first
protection seat 21 passing through the revolving combination place
of the cord 14, the male joining members 23 (screw for example) is
joined with the female joining members 231 (nut for example) such
that the first protection seat 21 and the second protection seat 22
are not only assembled as the completely cord protector 2 but also
combined with the cord 14 so as to protect the cord 14.
[0034] With references to FIGS. 8, 9, the cord protector 2
disclosed by the invention is combined with the revolving
combination place of the cord 14, and the outermost end of the cord
14 would pass through the joining perforation 161 at the tail end
of a hook head 16 to achieve combination. The cord 14 is also
combined on other appliances. Herein taking the cord 14 combined to
the "power winch" as an example, by comparing with two types of
installing cord on the conventional power winch shown in the
foregoing FIGS. 1, 2, with references to FIGS. 10, 11, FIG. 10 is
in contrast with the foregoing FIG. 1, the cord 14 performs a
motion of discharging or withdrawing via the cable entry 151 of a
discharging seat 15. However, the revolving combination place of
the cord 14 shown in FIG. 10 is further combined with the cord
protector 2 disclosed in the invention. The FIG. 11 is in contrast
with the foregoing FIG. 2, the cord 14 carries out a motion of
discharging or withdrawing via the cable entry 181 of a four-way
roller set 18. The revolving combination place of the cord 14 shown
in the FIG. 11 is also combined with the cord protector 2 disclosed
in the invention.
[0035] With references to FIGS. 10, 11, after the revolving
combination place of the cord 14 of the power winch is combined
with the cord protector 2 disclosed by the invention, finally the
cord protector 2 collides the discharging seat 15 or the four-way
roller set 18 when the cord 14 is withdrawn via power. Therefore,
loud noise generated from collision between metals in prior art has
been basically eliminated so as to have the following
efficacies:
[0036] 1. Since the cord protector 2 is made of flexible material
resisting impact, every impact force on the discharging seat 15 or
the four-way roller set 18 will be absorbed and buffered by the
cord protector 2 to protect any of the hook head 16, the
discharging seat 15 or the four-way roller set 18 so that
industrial safety issue can be prevented from occurring to protect
the operator.
[0037] 2. While retracting the cord 14, the cord protector 2 is
fastened between the hook head 16 and the discharging seat 15 or
between the hook head 16 and the four-way roller set 18 to avoid
direct contact between metals. Therefore, it can eliminate possibly
generated noise during vehicle idling such that emotion of persons
in vehicle will not be influenced.
[0038] 3. While retracting the cord 14, the cord protector 2 is
fastened between the hook head 16 and the discharging seat 15 or
between the hook head 16 and the four-way roller set 18 to avoid
direct contact between metals. Therefore, it can protect
completeness of each component of power winch and operation
accuracy.
[0039] The cord protector 2 disclosed by the present invention does
not only have novelty and non-obviousness but also has feature of
preventing collision between combined rigid components to protect
the combined rigid components and operating users so as to achieve
progressive effect of use safety and satisfies patentability.
[0040] While the present invention has been described by means of
specific embodiments, numerous modifications and variations could
be made thereto by those skilled in the art without departing from
the scope and spirit of the invention set forth in the claims.
