Provision field
[0001] This patent of utility model belongs to the field of safety equipment and is a practical
and innovative object model of a lumbar back safety belt to upkeep the positioning
of workers who perform services in high places, whose technology disengage their side
rings, in order to disconnect the straps, on fixed structures, by means of an attached
rigging driven by a third person, in cases where the user is temporarily unable, and
to which the original constructive data had been provided, aiming at improving its
utilization and performance in relation to other models of abdominal belts for positioning
and support usually found on the market.
[0002] It shows a belt with disengageable rings in the distance, which overlaps the back
belt that integrates the safety belt in uneven-level services, thus it introduces
a new technology to these safety belts, without the need to drop the original belt
and further making it highly economical without compromising safety, increasing it
otherwise.
[0003] Such application also aims at presenting a model of overlapping lumbar belt with
low costs for your industrial feasibility, but allied to the requirements of robustness,
safety and utility convenience, which offers an additional option to the public sector
in the sister-airline market, which unlike the usual models of safety belts, offers
countless possibilities and benefits to its users, making it a model of great sector
market acceptance.
Provision history
[0004] The safety belts are built with sturdy polymer transverse strips horizontally, vertically
and in oblique, whose intersection points between these are equipped with coupling
rings to attach the workers to the latch and/or strap, in order to retain and provide
security to workers who perform services in high or uneven leveled places.
[0005] These are responsible for preventing falls and keep workers attached to the rope,
and are crucial to maintain the security and physical integrity of the staff. Performing
activities at heights without them is extremely dangerous, also taking into account
that it is illegal, and its use is mandatory.
Technique status default aspects
[0006] When the worker performs services in high places, in addition to the "Vertical Life
Rope", it uses a positioning or constraining strap.
[0007] Such ' Vertical Life Rope"consists of a vertical (steel or nylon) cable that has
one of its ends connected to an anchor point or retractable latch, and the other end
is connected to the safety belt or sliding latch.
[0008] Positioning or constraining straps are devices consisting of high-strength nylon
rope or polyester belt with forged steel carabiners. Strap's purpose is to secure
the safety belt to the structure.
[0009] By having an accident or sudden pain, the employee will be suspended by the life
rope and latch. In this case, the positioning strap fixed to the structure prevents
its rescue, i.e., due to the positioning strap being fixed to the structure, the worker
cannot be lowered onto the ground.
[0010] At this point the rescuer should climb up to the victim to loosen the belt strap,
and leave the him/her attached to the lifeline only for the rescue, which occurs on
ground.
[0011] We must agree this operation shows a great deal of upset to the rescuer, besides
presenting certain risks and delays in rescuing.
[0012] One evident drawback in the market is that technological innovations applied in safety
belts show fairly difficulty in entering public enterprises, as well as private companies.
[0013] This occurs due to these companies' and institutions' need to dispose of the old
safety belts, in order to exchange them for newer and more modern ones in a technological
point of view, and it is not always possible due to the laws in force, financial conditions
and other adverse factors.
[0014] This commercial condition or difficulty in deploying new technologies apply to the
introduction of new safety belts with disengageable rings, necessary condition and
technology to rescue workers at heights, when he/she is unconscious due to an unexpected
problem.
[0015] Therefore, the inventor has developed an overlaid safety belt with disengageable
rings, which is installed by overlapping the original air belt and eliminates the
need to discard air safety belts used by companies and public institutions referenced
above.
Provision summary
[0016] Due to the need to develop a safety device to apply in safety belts so to not discard
them, reinforcing them with new technologies, led the inventor, a person related to
the business, to create and develop this patent object "provision introduced in overlaid
safety belt with disengageable rings", which comprises a safety device that takes
a new technology and utility feature that can be applied to safety belts without the
need to exchange them for new ones, since it innovates with a support belt that overlaps
on the original belt by attaching into their side rings hip and lumbar area.
[0017] The new rings set on the original rings, due to the installation of a belt to the
part overlapping the original lumbar belt, on which it is settled, allows them to
be disengaged by pulling on a rigging attached to them, through a person who is away
from the user in cases involving accidents.
[0018] By disengaging the new threaded rings, the worker can be rescued more promptly and
without any risk to third parties, when there is a rescue operation.
[0019] We can understand the overlaid belt for the safety belt in question is extremely
simple in your constructiveness, therefore, it is easily feasible, however, it obtains
excellent practical and functional results, offering an innovative constructiveness
on the known models.
[0020] Designed with an innovative drawing, it brings a harmonic set of a peculiar and,
above all, typical aspect, and besides the constructive aspect, the model stands out
due to its versatility and use convenience.

Detailed description of inclusion
[0022] According to the illustration in the figures above on how the related "provision
introduced in overlaid belt with disengageable rings", object of this patent, consists
of a vest-type safety belt accessory to protect and stabilize the user in services
performed at heights, whose technology comprises a belt that overlaps its original
(lower back) safety belt, in order to be able to release him from a distance, when
the user is unable to do so, therefore, allows it to be taken by a third person in
an innovative manner.
[0023] This overlaid belt has its ends connected to the original safety belt side rings
(on which the strap carabiners would be affixed) through the strips with Velcro fasteners
and it has two other rings equally positioned, however, able to be released along
with the strap (structural fixed back strap), if there is the need to rescue the user
who finds himself/herself in a risk situation and to be inoperable, in such heights,
without requiring the first rescuer to climb up the place to disconnect the strap
from the lumbar belt rings in order to lower the temporarily incapacitated (fainted)
worker down, sustained by a life rope, set to other safety belt anchorage points,
provided that they keep the user in totally safe conditions.
[0024] The overlaid belt can be manufactured in different ways and with different materials,
since it depends on its function, but it is usually made by a texture technique, using
strands of polyester, nylon, polyamide etc.
[0025] Operation of the overlapping safety belt.
[0026] The lumbar seat belt on which it attaches to a fixed strap in fixed structures is
a necessary option to equip such safety belts, usually set to other additional rings
and it focus on the comfort of a worker executing the service and how to ensure his/her
safety.
[0027] First, there was a time when this PPE was attached to the belt dorsal part and, on
the other hand, when Brazil began to carry out imports of more modern models, with
more anchor rings, industry began to modernize and provide more options for professionals,
as well as for imported safety belts.
[0028] More recently, it became obligatory to use front and rear double "Y" latch element,
along to the safety belt set, and thus offer more modern vest-type belts, which offer
several attachment or ring options for crimping, and not only on the dorsal area.
[0029] Knowing all the anchorage points means the user can choose the way it is most convenient
for
the function performance.
[0030] The overlaid safety belt with disengageable rings (1) includes a lumbar belt (2),
equipped with an elongated base strip (3), woven, produced with synthetic strands,
which is stitched in its center, another upper strip of smaller length, woven, containing
synthetic strands as well, which overlaps the original belt, in the same back abdominal
area.
[0031] In order to fix them to the side rings (18) of the safety belt (17), the base strap
(3) has a convergent hinged end at each end that gets fixed to that structure through
velcro-type couplings over which, after being folded, attaches and overlaps to a divergent
and opposed bluffed strip (15), fixed with velcro as well.
[0032] The upper strip (4) features an engagement fold (6) at each end, fixed to such structure
with reinforced stitching (7), preceded by a grommet (8), and along the upper strap
(4) it is attached under a lining (9), a double rigging (10), whose outer ends are
equipped with a metallic pin (11) and common ends hanging through a interspearse wheel
(12) set to the external center of the upper strip (4).
[0033] A double rigging (13) connected by a specific technique by respective engagement
folds (6) and, that finish across by the grommets (8), providing support and fixing
the respective allocated disengageable ring (14), each at the ends of the strip (4),
which can be disconnected after a manual pull by the common ends of double riggings
(10), showing a substantial length.
[0034] To provide a better finishing, a soft woven sleeve covers the upper strap (4) in
the metallic pin (11) crimping area of the rigging (10) and (13), where it gets overlapped
both crosswise, by a woven clamp equipped with velcro, which also involves the base
strap (3) and upper strap (4).
[0035] Therefore, this descriptive report depicts a new design of overlaid safety belts,
as it can be seen by analyses carried out and figures shown, numerous differences
over conventional models of individual safety equipment for the same purpose on the
market, as well as constructive and functional technical characteristics quite different
from those relevant to the state of the art.
[0036] By the advantages it offers, and still, for showing truly innovative features that
meet all the requirements as to innovation and originality in the genre, this "provision
introduced in overlaid safety belt with disengageable rings" gather the conditions
needed to merit a patent of utility model.
