Description
BACKGROUND OF THE INVENTION
The present invention relates to beauty shop equipment, and more
particularly to a tray-supporting device attachable to a beauty
shop chair having a central piston and upstanding base on which the
device is wholly supported for easy turning and convenient location
of the tray around the chair within easy reach of the beauty
operator working in the area adjacent to the chair.
A beauty shop customer or patron usually prefers to sit in the
chair facing a mirror so that she can watch the progress of the
work being done and indicate her desires relative thereto. Beauty
shop items, such as hair rollers, pins, shears, bottles of liquids,
etc., used by the beauty shop operator or worker are normally
carried in trays supported on carts or bases having caster wheels.
These tray supports are always getting in the way of the operator
as she moves about in the course of work, and often get knocked
over, creating a mess which has to be cleaned up. Further time and
effort are required to restore the items to sanitary working
condition. While broadening the wheelbase of the tray support
increases its stability, it also increases the amount of floor area
occupied thereby, with an even greater possibility of the operator
tripping thereover. Furthermore, the tray support is difficult to
wheel about, especially when there is a cushioned pad on the floor
on which the beauty operator stands.
In some shops, the trays are placed on a stationary table or bench
located adjacent to the chair, and the operator stands nearby,
swinging the chair as necessary during the progress of the work on
the patron. While this is somewhat of a solution to the problems
presented by the aforementioned wheel-type bases, the patron cannot
always watch the work which sometimes progresses contrary to the
desires of the patron, and results in work which must be redone or
else you have a dissatisfied customer. Moreover, in addition to the
effort required to swing the chair, the operator has to stand for
extended periods in substantially one spot, which is more tiring
than where there is opportunity to move about during the work.
However, when greater movement is involved, the operator is often
at a considerable distance from the tray when an item is needed.
Thus, when the operator is holding the customer's hair with one
hand an overly long reach is required by the other hand with a
greater chance of disturbing the hair or dropping the item, thus
adding to the time required for the job, and making the work more
fatiguing.
In view of the foregoing, it is clear that any device which would
not clutter up the work area and which serves to locate items
conveniently within reach of the operator as she moves about in the
course of work would minimize the danger to and improve the
efficiency of the beauty operator, thus benefiting the beauty shop
industry greatly.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a
tray-holding device of simple, inexpensive construction which is
easily movable and does not clutter the work area of a beauty
operator, yet serves to locate the tray conveniently within easy
reach of the operator, for the safety, comfort and efficiency of
the beauty operator.
Another object of the invention is to provide a device which
supports the tray for positioning along a path concentric with the
central axis of a beauty shop chair and at optimum level within
easy reach of a beauty operator working in the area around the
chair.
A further object of the invention is to provide a device which is
readily attachable to a hydraulic lift beauty shop chair, and
supports the tray for easy movement to various positions around the
chair conveniently within the reach of a beauty operator working in
the area adjacent to the chair, regardless of the height of the
chair.
These and other objects and advantages of the present invention are
achieved by the provision of a tray-supporting device attachable to
a hydraulic lift beauty shop chair having a central piston and an
upstanding base. The device includes a sleeve which is coaxially
fitted to the piston for free turning about the axis thereof and
rides on the upper end of the upstanding base. A bent piece of
tubing has an arm portion fixed to the sleeve and an upright post
spaced an optimum distance from the piston axis for disposition
over the area in which a beauty operator works during a beauty
operation. The post is movable along a path concentric with the
piston axis, and carries a tray, or trays, which can be located
conveniently for the operator. The trays are adjustable for
mounting at optimum levels and are free to turn on the post to
provide easy access to the contents thereof.

DESCRIPTION OF PREFERRED EMBODIMENT
Referring to FIG. 1, there is shown a beauty shop chair 8 and a
tray-supporting device 10 embodying the principles of the present
invention. Typically, the chair is of the hydraulic lift type
having an upstanding base 12 in which a vertically movable piston
14 is slidably fitted. The piston constitutes the sole central
support of a chair seat 16, having the usual backrest 18, armrests
20, and footrest 22, as shown in FIG. 2. The lower end of the base
12 is fixed to a broad floor plate 24, and its upper end 26 defines
a circular surface disposed in a horizontal plane. Pivotally
mounted on the base are the usual levers 28 and 30, operable in
well-known manner for raising and lowering the piston.
The device 10 includes a length of metal tubing 32 bent to the
curved configuration shown to provide an upright post 34, and a
laterally extending arm 36. The post supports a pair of trays 38,
and the arm is fixed to a sleeve 40. The sleeve surrounds the
piston 14, and is coaxially fitted thereto for free turning about
the axis A thereof, as shown in FIG. 3. The lower end of the sleeve
is in engagement with the upper end 26 of the base 12, and rides
thereon during turning. During turning of the sleeve, the post 34
generates a surface of revolution which is concentric with the axis
of the piston. Thus, the trays 38 move along a path concentric to
the piston axis.
The length of the arm 36 is chosen to place the post 34 at an
optimum distance beyond the chair to clear the lateral projections
thereof and locate the path of the trays over the floor area around
the chair in which the beauty operator moves about and works in
performing a beauty operation. Such work area is generally defined
by the usual cushioned pad 42, provided for the operator to stand
on and fragmentarily shown in FIG. 1. It is to be noted that the
trays are wholly supported by the chair, independently of the work
area defined by the pad, and therefore leave the area uncluttered.
It is also to be noted that the piston 14 can be raised and lowered
without disturbing the level of sleeve 40, whereby the level of the
trays 38 is maintained the same throughout the various positions of
the chair.
As better shown in FIG. 2, each of the trays 38 is formed with ribs
44 to provide compartments for holding hair rollers, pins, shears,
bottles of fluid, and other items. Each tray is also formed with a
central hub 46, through which the post 34 extends. Inviting
attention to FIG. 4, each tray is adapted to be maintained at
desired optimum level by a supporting collar 48. Each of the
collars is slidably adjustably fitted to the post 34, in underlying
relation to its tray, and is fixed to the post in desired position
of adjustment by a setscrew 50. Once the optimum level of a tray is
determined, such level is maintained throughout the various
positions of the tray around the chair. The hubs of the trays are
preferably journaled on the post 34 for easy turning of the trays
to avoid the requirement for a long reach and provide easy access
to the items contained in the trays.
The operation of the present invention is believed to be clearly
apparent and is briefly summarized at this point. Depending upon
the height of the beauty shop operator, the collars 48 are adjusted
to dispose the trays 38 at optimum level for the operator. With a
customer in the chair 8, the levers 28 and 30 are actuated, as
necessary, to dispose the customer at a convenient level for the
operator. The operator then works on the customer, moving about in
the work area as necessary, and pulling or pushing the post or a
tray to locate the trays conveniently for the work at hand. Where a
needed item is at the opposite end of the tray from the operator,
the tray is easily turned to provide access to the item without
need of stretching or overreaching. Should the operator
accidentally bump the trays, they merely move away, rather than
overturn or trip the operator.
In view of the foregoing, it is readily apparent that the device of
the present invention provides a tray support which leaves the work
area around a beauty shop chair relatively clear and uncluttered,
while providing for locating the trays at optimum level within
convenient reach of the beauty operator working in the area around
the chair, thus adding to the safety and efficiency of the
operator.
Although the invention has been shown and described in what is
conceived to be the most practical and preferred embodiment, it is
recognized that departures may be made therefrom, and that the
invention is not to be limited to the details disclosed herein, but
is to be accorded the full scope of the claims that follow. For
example, a split ring could be used in place of the sleeve and the
post could be fixedly connected to the arm rather than formed
integrally therewith.
