Description
This invention relates to a readily accessible multipurpose
beauticians tray and improved arm means for supporting and
elevating the tray for serviceable and feasible use and
complemental means through the medium of which a lower end of the
arm means is operatively connected with a component part of a
hydraulic chair structure such as is in widespread use in beauty
salons and equivalent establishments.
Plastic and equivalent dished trays which are popularly in use in
beauty salons are supportively perched atop the upper end of a
vertical standard which is a component part of a tripodal-type
stand, that is, a stand whose outer leg-ends are provided with
casters or the like, whereby the tray equipped stand can be pushed
and shoved around atop the floor, often in limited and crowded
quarters. These trays are used, as is known, for supporting
utensils, implements, hair rollers and other accessories which are
selectively usuable by the beautician. However, and as repeated
experience has shown, loose hair gets caught and tangled in the
rollable wheels of the stand in a manner that the stand is not
freely mobile. The floor space available to the beautician has to
be ample and in the course of daily activities, it is not unusual
for the stand to be accidentally toppled over. If follows that it
is an object of the present concept, generally stated, to attach,
that is, movably mount the tray on a convenient and accessible part
of the hydraulic or other type chair and to be able to utilize it
in the available space with freedom and certainty. Experience has
shown that the improved tray and supporting and mounting means
enables the user to expeditiously and conveniently cope with and
overcome spillage problems, to minimize the hair entanglement
difficulties, to arrange the tray so that it is always within reach
of the worker and to be able to move the tray to an out-of-the-way
position when it is not being used.
Briefly the invention, construed from a ready-to-use combination
standpoint, has to do with a chair structure of a type such as is
in widespread and common use in beautician salons and customer
serving establishments, more particularly, a chair embodying a
vertical pedestal with a holddown and floor mounting base at the
bottom and an elevated suitably designed chair at the top. The tray
used may be, and preferably is similar to deep dished trays which
are commonly used for diversified articles and implements. The tray
holder is characterized by a elevating and supporting arm, that is,
an arm which has an upper end portion and a lower end portion. The
tray is accessibly supported on the terminal end of the upper end
portion. Adapter means is operatively mounted on the lower end
portion of the arm and also operatively mounted, usually rotatably,
on a convenient part for example, the pedestal, of the chair
structure.
More specifically, the holder is characterized by a tubular or an
equivalent arm of requisite strength and height, that is, an arm
which is usually substantially L-shaped in side elevation and has a
lower horizontal end portion and an upper vertical portion, the
latter supporting the tray. The lower horizontal end portion is
connected to adapter means which is cooperatively supported on a
part of the chair structure, and said lower end portion is radial
as a general rule, to the vertical axis of the pedestal or
standard. The upper end portion assumes an outwardly offset locale
in a manner to swing freely in an orbital path around and free of
collision with any part of the chair. It follows that this type of
a holder or arm functions to support and swing the tray and enables
one to position it in an out-of-the-way place when not in use and
conveniently swung in a restricted path or working space, whereby
it is available for feasible and convenient use by the
beautician.
In carrying out a feasible and practical embodiment of the
invention the adapter means comprises an inner annulus or ring
which is channel-shaped in cross-section with the open side of the
channel facing outwardly and providing a raceway. This inner ring
is surrounded by a coplanar outer ring which is also channel-shaped
in cross-section and whose inner peripheral portion is provided
with circumferentially spaced anti-friction rollers. The raceway
provides a track and the rollers are confined and movable around in
the track whereby the outer ring can be aptly and successfully used
for angling the lower end of the L-shaped tray positioning arm.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout, and
in which:
FIG. 1 is a view in perspective showing a beauty salon-type chair
or chair structure, an elevated movably mounted article tray, the
elevating and supporting arm for the tray and the adapter means
operatively joining the arm to the chair structure;
FIG. 2 is an enlarged detail view taken on the plane of the
horizontal section line 2--2 of FIG. 1, looking in the direction of
the arrows and with parts appearing in section and elevation;
FIG. 3 is a sectional view taken approximately on the plane of the
irregular section line 3--3 of FIG. 2; and
FIG. 4 is a view similar to FIG. 3 showing a modified form of the
concept wherein the inner ring is secured by Z-shaped or equivalent
brackets to the base of the pedestal.
It will be evident from FIG. 1 that the chair structure of the
construction shown is denoted generally by the numeral 6 and is
exemplary of a generally well known hydraulic type beauty salon
chair. The support means for the chair comprises a base 8 which is
circular and fastened on the floor 10 and which is axially provided
with a vertically and swivelly adjustable structure which is here
referred to as an adjustable pedestal 12 comprising a hydraulic
cylinder 14 mounted on the base, a piston 16 and an appropriate
chair 18 which is mounted atop the piston. Other details are
illustrated but need not be dwelled upon here.
The multi-purpose instrument and article tray is of appropriate
construction and it is denoted by the numeral 20. The invention can
be made as a part of the original chair at the time of sale or can
be characterized as an attachment which is susceptable of
installation on chairs which are currently being used. The
elevating support and holder for the tray is denoted at 22, and,
more specifically, comprises a tubular or an equivalent arm which
can be set forth as substantially L-shaped in side elevation. The
median bend or bent portion 24 serves to interconnect a horizontal
lower end portion 26 with a substantially vertical upper end
portion 28 to which a component part 30 of the tray is connected.
The terminal of the end portion is connected to a component part of
the chair 6 by way of novel means. The means which has been
successfully adopted for the result desired is characterized by an
assembly of coacting component parts. In the adaptation shown in
FIGS. 1-3 inclusive there is an inner ring 32 and a companion
concentric encompassing outer ring 34. The inner ring is made up of
a bottom annulus 36 (FIG. 3), a top annulus 38 and an intervening
annular web 40 and in actual practice the upper and lower edges of
the web can be provided with lugs which are fitted into holes
provided therefor and welded or otherwise anchored in place as
indicated generally at 41 in FIG. 2. These upper and lower annular
members 38 and 36 have offset portions 42 which coact in providing
a circular raceway for the anti-friction freely rotatable bearings
or rollers 44. These rollers are carried by a web portion 46 of the
outer ring 34 which is likewise in the form of an outwardly opening
channel. More specifically, the axles 48 of the wheels or rollers
42 are swivelly mounted on the web of the channel, as is evident in
FIGS. 2 and 3 in particular, and thus the assembly comprises an
inner channel or ring 32 and a concentric encompassing outer
channel ring 34, the inner ring having an endless raceway or track
for the wheels or rollers on the web of the outer ring 34. The
inner ring 32 can be made of half-sections which are butted
together as designated at 50 in FIG. 2. The outer ring is also made
up of semi-circular half-sections which have abutting flanges 52
which are bolted or otherwise connected at 54. By making the rings
in half-sections they can be assembled and fastened into place
expeditiously.
Two ways are shown whereby the inner ring can be attached to the
coacting column of the pedestal. One arrangement comprises
substantially U-shaped brackets 56 (FIG. 2), these brackets being
circumferentially spaced and provided with setscrews 58. This is to
say, the web 60 of each bracket is provided with upper and lower
setscrews which are secured to the outer peripheral surface of the
pedestal in the manner shown for instance in FIG. 3. The arm
portions of the brackets 56 are wedged into place between the upper
and lower annular members 36 and 38 as is evident from FIG. 3. A
U-shaped bracket or anchor member 62 is provided for fastening the
cooperating terminal end portion 64 of the lower arm portion 26 to
the channel of the outer ring 34 as brought out in FIGS. 1-3. More
specifically the terminal end portion 64 is bolted or otherwise
secured at 65 to the bracket at 65 and the bracket is suitably
anchored between the flanges in the channel (FIG. 3).
Another way whereby the inner ring can be mounted and which omits
the use of the U-brackets 56 is shown in FIG. 4. This modification
comprises circumferentially spaced substantially Z-shaped brackets
66. One end portion 68 is secured in place on the base as at 70 and
the upper end portion 72 is welded or otherwise connected to the
lower annular member of the inner ring 32 and the intermediate
portion 74 provides an elevating and spacing member for the dual
ring assembly. Inasmuch as the rings are the same as already
described they are referred to by like reference characters.
The purpose in showing two ways of attaching the rings is to bring
out the fact that the arm adapter means can be constructed in ways
other than illustrated and can be anchored and mounted in place in
keeping with the requirements of manufacturers and users.
It is submitted that the views of the drawings clearly show the
overall attachment and the component parts thereof which have been
found satisfactory for practical and successful use. Inasmuch as
the features and advantages have been set forth and the mode of
mounting and use is substantially self evident a more extended
description is deemed unnecessary.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention.
