Description
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to a belt for use by lineman engaged in
climbing utility poles, or persons engaged in similar occupations;
and particularly to such a belt having means for preventing
downward sliding of the belt in the event the user loses his
foothold on the pole.
Most lineman's belts which are used at the present time consist of
a tool belt which encircles the body of the lineman, and which is
referred to hereafter as a body belt, and a safety belt which is
adapted to be secured thereto by means of snaps and which extends
about the pole to allow the lineman to lean outwardly with his feet
spurred to the pole to balance himself. In this position, the
lineman is supported at three points, namely the two spurs strapped
to each foot and the pole encircling strap, and this support allows
the lineman to lean away from the pole to allow working distance
from the pole so that he may reach out and perform such tasks as
are required. However, should the lineman lose the support of
either one or both of his foot spurs for any reason (and one common
reason is electric shock), the weight on the safety strap is
relaxed and the strap then loosely encircles the pole and allows
the lineman to drop. It has been found that such a drop is more apt
to kill a lineman while unconscious, but in any event such a drop
normally results in at least serious injury to the lineman.
Since the safety strap is maintained in position by tension, one
dangerous and likely condition occurs where the lineman while,
working on cross arms, insulators or the like, moves his body
inwardly toward the pole with a resulting slackening of the belt
allowing it to drop downwardly to a dangerous position without his
awareness of this situation. When he then leans back to again
tension the belt, he is overbalanced and may easily lose his
footing.
An object of this invention is to provide a lineman's belt which
will prevent or minimize any downward slipping of the belt in the
event of the loss of footing for any reason.
Another object of this invention is to provide an improved
lineman's belt having means for relatively closely gripping the
pole to obviate any inadvertent downward sliding of the belt, and
yet to permit the lineman to lean outwardly from the pole as
required to perform his usual tasks.
A further object of this invention is to provide an improved
lineman's belt having means for relatively tightly engaging the
pole during use, and also during ascent and descent, to prevent
downward slipping of the belt on the pole in the event of loss of
footing.
Still another object of this invention is to provide an improved
lineman's belt having means for relatively closely encircling the
pole, and having means for ready manipulation by the user to
facilitate ascent and descent of the pole.
These objects are accomplished in a lineman's belt which includes a
safety belt component for attachment to the body belt component.
The safety belt component includes an elongated strap having snap
hooks attached at each end for coupling to attachment rings or
loops of the body belt component, and a pole belt which is attached
to the safety strap for closely encircling the pole. Means are
provided for coupling the pole belt at its midlength point to the
safety strap at its midlength point, whereby the coupling means is
positioned at the far side of the pole in use. The pole belt has
buckle means for coupling its free ends at the front face of the
pole in use; and also has barb means attached to it along the
middle portion and being disposed to bite into the pole at the rear
and side faces relative to the user. Handle means may be provided
on the pole belt adjacent to its free ends to be grasped by the
user to manipulate the safety belt component particularly during
ascent and descent. Preferably the pole belt is hingedly coupled to
the safety strap.
The novel features and the advantages of the invention, as well as
additional objects thereof, will be understood more fully from the
following description when read in connection with the accompanying
drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The illustration of FIG. 1 illustrates all of the components and
parts of a lineman's safety belt according to the invention; the
principal components being the body belt 10 and the safety belt 20,
with the safety belt component including an auxiliary pole belt 30.
As best seen in FIG. 2, in broken lines, the body belt 10 includes
a belt portion 11 which encircles the users body and is buckled
tightly around his waist, and may include accessories for carrying
various types of tools and supplies which would be used by the
lineman for example. The body belt also includes side extensions 12
which carry loops or rings 13 at their ends to which the safety
belt component is attached.
As best seen in FIG. 2 the safety belt component consists of an
elongated strap 21 having a snap hook 22 securely attached at one
end and having a snap hook 23 secured to the other end, said other
end having adjustment means such as a looped end and a buckle 24
for adjusting the overall length of the safety strap.
Alternatively, both ends of the safety strap might have such
adjustment means.
The auxiliary pole belt includes a separate belt or strap 31 having
a suitable length to encircle the poles of intended use, with the
pole belt having coupling means such as a conventional belt buckle
for buckling or coupling the free ends around the pole in use.
It should be mentioned here that all of the belts or straps which
make up portions of the body belt component, the safety strap and
the pole belt are fabricated from suitable belting material which
may be high quality leather or suitable fabric belting material,
for example.
As best seen in FIGS. 2 and 3 the pole belt strap 31 is coupled at
a midlength point or area to the safety belt strap 21 at its
midlength point or area, by means of an elongated hinge strap 33
which overlies adjacent edges of the safety belt strap 21 and the
pole belt strap 31 and is secured thereto by stitching 34. Rivets
35 may be employed to secure the ends of the hinge strap to the
respective coupled straps. Preferably the adjacent edges of the
straps 21 and 31 are slightly spaced from each other, and the hinge
strap is fabricated of suitable material such as leather which will
permit flexing at the adjacent coupled edges. While this hinge
strap 33 is illustrated and described as a preferred form of
coupling between the safety strap and pole belt, it will be
understood that other suitable forms of coupling may be used.
Four elongated metal barbs 36 and 37 are fabricated from strap
metal for example, and have their upper ends secured to the pole
belt by means of rivets. The free ends of the barbs then project
downwardly from the pole belt, as best seen in FIG. 3, with the
free ends being formed into sharpened points and preferably being
bent inwardly relative to the plane of the pole belt strap to
encourage engagement with the pole surface. By way of example, two
of these barbs 36 are positioned at the midportion of the pole belt
which would normally be disposed at the far or rear face of the
pole relative to the user when in use. The two additional barbs 37,
as best seen in FIG. 2 are positioned toward the free ends of the
pole belt strap where they would normally be disposed along the
side faces of the pole relative to the user. In particular
applications it may be desirable that a lesser or a greater number
of barbs be mounted on the pole belt.
Also secured on the pole belt, as seen in FIG. 2, are a pair of
handles 38 preferably in the form of luggage type handle grips
which are positioned toward the free ends of the pole belt straps
so that they will be toward the near face of the pole in the use
condition. These handles, then, are in good position to enable the
lineman to lift the pole belt 30 and the attached safety belt strap
while ascending a pole, and also to manipulate the pole belt to
free the barbs and permit descent of the pole while retaining the
pole belt in the use condition for availability in the event of
loss of footing.
A particular feature of the above described hinge connection is
particularly illustrated in FIG. 5. This figure is intended to
illustrate the condition of portions of the safety belt component
relative to the rear face 40 of a utility pole when a lineman has
lost his footing. While the belt straps as above described are
flexible, they are relatively heavy and do have a certain
stiffness. When a lineman is hanging by his belt then the safety
strap 21 of the safety belt component will tend to assume the
position illustrated with its upper edge bearing against the face
of the pole and with its lower edge pulling away from the pole. The
coupling of the hinge strap 33 will then pull the upper edge of the
pole belt strap 31 away from the pole face with the hinge
connection then urging the lower edge of the strap 31 toward the
pole face encouraging the barbs 36 to dig into the pole face and
prevent sliding of the pole belt. This of course is the purpose of
applicant's lineman's belt assembly; and this particular hinge
arrangement enhances that purpose.
What has been described is a novel and useful improvement in a
lineman's belt which provides greatly increased safety and
protection for the user; and at the same time does not present such
a complex and cumbersome arrangement such as to discourage the use
of the safety feature by the lineman whose safety is intended to be
protected. This positive protection is not in evidence on any
lineman's safety belt being marketed or used today.
While the preferred embodiment of the invention has been
illustrated and described, it will be understood by those skilled
in the art that changes and modifications may be resorted to
without departing from the spirit and scope of the invention.
