FIELD OF THE INVENTION
This invention relates generally to apparatus for removing toxic fumes.
More specifically, the invention relates to an apparatus for use in
sculpturing finger nails, wherein means is provided for removing toxic
fumes from the work area.
DESCRIPTION OF THE PRIOR ART
Various methods and devices exist in the prior art for repairing broken
finger nails, and/or for applying false or artificial nails. One such
method which has gained substantial popularity is the application of
acrylic materials to form a sculpted nail. In some instances, these nails
are produced for later application to the fingers of a customer, but many
beauty salons and shops specializing in nail care construct the sculpted
nails directly on the fingers of a customer. The manufacture of such nails
requires the use of a number of toxic materials, including solvents and
hardeners and the like. In particular, such materials typically contain
ethyl methacrylate, which is a highly toxic material that can cause
hypotension, headaches, shortness of breath and nausea, and can even lead
to cardiac arrest.
Nail technicians typically work at a small table, with the customer seated
on one side and the technician seated on the other side. The customer's
fingernails are prepared with solvents and the sculpted nail is then built
up using acrylics. Multiple applications are usually made, each followed
by a drying period during which volatile components evaporate into the
atmosphere, and sanding to shape the nail. During this process, cotton
balls,tissues and other tools become saturated with the chemicals. As a
result, a substantial quantity of toxic fumes are introduced into the
atmosphere surrounding the work table, leading to potentially serious
consequences for both the nail technician and the customer. The problem is
particularly acute for the technician, who often performs nail sculpturing
services for many customers during the course of a day. In many shops
which have multiple work stations, toxic fumes can reach hazardous levels
throughout the shop, endangering all of the customers and employees in the
shop.
In an effort to alleviate these problems, exhaust fans and/or hoods have
been provided in some prior art facilities to vent the toxic fumes away
from the work area. However, these devices typically only reduce the
amount of toxic fumes in the atmosphere and do not eliminate them, since
they are not constructed to substantially enclose the work area and/or to
remove both the heavy and light components of the toxic fumes. In this
regard, it should be noted that materials used in the sculpting of nails
include components which are lighter than air and components which are
heavier than air. Consequently, a simple hood and exhaust fan will only
draw away the lighter components. Moreover, if the work area is not
enclosed, a substantial amount of fumes can escape the influence of the
exhaust fan.
Similar problems have been encountered in other professions, such as in the
fields of graphic arts, histopathology and manufacture of ceramic objects.
In PALMER, et al. (U.K. Pat. No. 778,321) an apparatus is disclosed for
removing the toxic dust and particles resulting from the fettling of
ceramic ware. In this apparatus, work is performed on a mesh platform 12,
through which dust and particles fall into a drawer 11. Lighter dust
particles are drawn through exhaust 20, 22. The platform work area is
enclosed on three sides by a wall 16, the exhaust outlet 21 and a hood 17.
The worker gains access to the work through the open side of the
apparatus. There is no thought or suggestion of two persons having access
to the work platform from opposite sides, or of using exhaust fan means to
draw both heavy and light components of toxic fumes from the work area, or
of providing reversible drawers, lighting means, etc.
The patent to GOLDMAN (U.S. Pat. No. 4,512,245) describes an apparatus
intended for use in histopathology or graphic arts, in which a curved pipe
15 has an intake 60 on one end thereof disposed closely above a work
station for drawing lighter than air fumes. Heavier than air fumes are
exhausted downwardly through the work platform itself. However, this
patent fails to suggest the unique combination of elements, including the
hood with openings on opposite sides for gaining access to the work
platform by a technician and a customer, or the light means, or the
reversible drawers, etc.
U.S. Pat. No. 4,359,060 to WALKER discloses an apparatus for dispensing
nail polish, in which pivoted brackets 31 and 33 are mounted on a
superstructure 12. The object of this patent is to provide a means for
enabling nail polish and remover to be dispensed without spilling the
polish and remover over rugs, clothes or furniture. There is not any
exhaust means or hood disclosed as contemplated in the present invention,
nor are there reversible drawers, light means, etc.
SUMMARY OF THE INVENTION
Accordingly, it is an object of this invention to provide an apparatus for
venting toxic fumes from the work area during sculpting of fingernails.
A more specific object is to provide an apparatus for collecting and
venting both heavier than air and lighter than air components from a work
area during sculpting of fingernails.
Another object is to provide a work station for sculpting fingernails, in
which a platform is provided for supporting the hand(s) of the person
whose nails are being sculpted, with vent means in the platform for
venting away heavier than air components of toxic fumes emitted during the
sculpting process, and in which a hood substantially encloses the area
above the platform for exhausting the lighter than air components.
A further object of the invention is to provide a work station for
sculpting fingernails, wherein a work platform is supported on a base or
pedestals including stacked drawers which are reversible in their pedestal
to change the work station form a right-hand configuration to a left-hand
configuration.
Yet another object of the invention is to provide a work station for
sculpting fingernails, in which a vented platform is provided for
supporting the hands of a person whose nails are being sculpted and a
vented hood is positioned over the platform for collecting and venting
both heavier than air and lighter than air toxic fumes form the work area,
respectively, the hood having low profile elongate slots for access of the
hands of the nail technician and the customer during the sculpting
process.
An even further object of the invention is to provide a work station for
sculpting nails, in which a transparent vented hood is supported above a
vented work platform, with low profile access slots on opposite sides of
the hood for enabling the nail technician and the customer to place their
hands over the work platform from opposite sides of the hood.
Yet another object of the invention is to provide a low maintenance vented
work station for sculpting nails, wherein toxic fumes are vented away from
the work area by an exhaust fan.
These and other objects and advantages of the invention are achieved by the
unique and simple apparatus discovered by applicant, wherein a work
platform is supported at its opposite ends on pedestals. One of the
pedestals comprises a stack of drawers which are reversible in the
pedestal to convert the work station for use by either a left-hand person
or a right-hand person. The platform is vented for removing heavier than
air fumes emitted during the nail sculpting process. A transparent hood is
mounted on the platform above the work area, completely enclosing the work
area except for a low profile slot on each side through which the hands of
a customer and a nail technician may be inserted for access to the work
platform. The hood is ventilated for drawing away lighter than air
components emitted during the sculpting process, and a light is positioned
in the hood to provide light to the work area. The exhaust means for
venting the toxic fumes away from the work area comprises a simple duct
system and exhaust fan, and does not include any filters or other
equipment requiring service or periodic replacement, thus rendering the
apparatus relatively maintenance free. The resulting work station is
exceptionally simple and inexpensive to manufacture and use, and provides
an environmentally safe means for performing nail sculpting services.
BRIEF DESCRIPTION OF THE DRAWINGS
The foregoing objects and advantages will become apparent from the
following detailed description and accompanying drawings, wherein like
reference characters designate like parts throughout the several views,
and wherein:
FIG. 1 is a top perspective view of the work station of the invention;
FIG. 2 is a front view in elevation of the work station, showing the drawer

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring more particularly to the drawings, the work station is indicated
generally at 10 and comprises a flat, rectangularly shaped work platform
11 supported at its opposite ends on pedestals 12 and 13. One of the
pedestals contains a stack of drawers 14 which are reversible in the
pedestal to convert the work station from use by a left-hand person as
shown in FIG. 1 to use by a right-hand person as shown in FIG. 2. The
drawers 14 are used for storing supplies, tools, and the like for use in
sculpting nails. In addition, the work platform includes an end portion 15
which remains unencumbered for holding various tools and materials used
during a nail sculpting process.
Slots 16 in the work platform communicate with a collector 17 concealed
within the work platform, and the collector is connected with an exhaust
duct 18 joined to a T-connector 19 at the side of the platform. The
T-connector is intended to be joined to an exhaust duct (not shown)
leading to a suitable fan means (not shown) for conveying heavier than air
fumes downwardly through the slots and outwardly through the ducts to a
site away from the work environment.
A transparent hood 20 is supported on the work platform and includes
opposite end walls 21 and 22, downwardly sloping top walls 23 and 24, and
a collector 25. Duct 26 is connected with the collector 25 and leads
through an elbow 27 and duct 28 to the T-connector 19, whereby lighter
than air fumes are trapped under the hood and are conveyed through the
ducts by the exhaust fan and away from the work area. As seen best in FIG.
4, the bottom edges of the end walls 21 and 22 are received in slots 29
and 30 formed in the top surface of the platform to stabilize the hood on
the platform and to ensure that the fumes are confined to the area under
the hood.
The bottom ends or edges of the top walls 23 and 24 are spaced closely
above the top of the platform to define low profile access slots 35 and
36, through which the hands of a nail technician and a customer can be
extended to rest on the work area of the platform above the slots.
The transparent panels of the hood can be made of any suitable material,
such as plastic or glass, and are joined at their mating edges by suitable
couplings, such as metal or plastic strips 37.
A light fixture, such as fluorescent light 40, is supported in the hood at
the top of the collector for providing adequate light to the work area,
and switches or controls 41 and 42 for operating the light and/or the
exhaust fan are mounted in the top of the platform on opposite sides
thereof for convenient access by the nail technician from either side of
the work station.
In use, a nail technician sits on one side of the platform and a customer
sits on the other side, with their hands inserted through the access slots
35 and 36. The transparent hood enables both the customer and the
technician to readily view the work, and at the same time substantially
all of the toxic fumes emitted during the sculpting process are captured
by the hood and vented away from the work area.
Although the invention has been described with reference to a particular
embodiment, it is to be understood that this embodiment is merely
illustrative of the application of the principles of the invention.
Numerous modifications may be made therein and other arrangements may be
devised without departing from the spirit and scope of the invention.
