Abstract
A chair is provided with a seat and a base for securing the chair to the floor. A footrest secures to the seat, and a linking mechanism moves the footrest between an extended and a retracted position. The linking mechanism comprises a bracket that allows the footrest to pivotably mount thereto. A handle pivotably secures to the bracket and a first end of a first link. The second end of the first link pivotably secures to the first end of a second link, and the second end of the second link pivotably secures to an additional pivotable mount on the footrest. Movement of the handle moves the footrest between the extended and retracted positions.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a retractable footrest for a hairstyling chair. In particular, a retractable footrest that uses a linking mechanism to move between an extended and a retracted position.
Standard U-shaped footrests, of the type commonly attached to hairstyling chairs, are well known and in wide spread use. While the footrest is convenient and easy to use when a person is seated in a hairstyling chair, the footrest can make getting in and out of the chair difficult. Because the footrest typically is fixed in an extended position, it creates a barrier that prevents a person from getting close enough, to comfortably and safely enter and exit a traditional hairstyling chair.
Accordingly, a need exists for a hairstyling chair that includes a footrest that allows a person to more easily enter and exit the chair.
SUMMARY OF THE INVENTION
An object of the present invention comprises providing a retractable footrest for a chair.
These and other objects of the present invention will become apparent to those skilled in the art upon reference to the following specification, drawings, and claims.
The present invention intends to overcome the difficulties encountered heretofore. To that end, a chair is provided with a seat and a base for securing the chair to the floor. A footrest secures to the seat, and a linking mechanism moves the footrest between an extended and a retracted position.

DETAILED DESCRIPTION OF THE INVENTION
In the Figures,
FIGS. 1
a
and
1
b
show a footrest
10
from a top view and a side view. The Figures also show a linking mechanism
14
that includes a handle
12
, and various other components, which will be disclosed in detail herein.
FIG. 1
a
and
1
b
show the linking mechanism
14
in a position such that the footrest
10
is extended.
FIGS. 2
a
and
2
b
show the linking mechanism in a position with the footrest
10
retracted. In the retracted position, the footrest
10
is conveniently tucked below the seat portion of the chair (not shown). This allows a person to enter and exit the chair unhindered by the presence of the footrest. Once seated in the chair the handle
12
can be manipulated to extend the footrest to the positions shown in the
FIGS. 1
a
and
1
b.
In detail,
FIGS. 3
a
and
3
b
show that the linking mechanism
14
is secured to the underside of the chair with the mounting bracket marked Detail
1
shown in
FIG. 3
a
, and
FIG. 3
b
, and in greater detail in FIG.
8
. In order to fit the bracket to the bottom of a chair, a wedge or similar device may be needed to conform to the surface of the bottom of the chair.
FIG. 3
a
shows a portion of the invention from the top view, which shows that Detail
1
includes two boltholes
16
used to attach the linking mechanism
14
to the footrest
10
, and the chair. Detail
1
secures directly to Bracket
1
, which is shown in particular detail in
FIG. 3
b
. Bracket
1
contains a plurality of holes
16
designed to allow attachment of the components of the linking mechanism
14
, which allows the footrest
10
to pivot between the retracted position and the extended position.
In particular, the footrest
10
secures to Bracket
1
through a collar
18
which attaches through the bolthole
16
located in the upper left hand portion of Bracket
1
. The footrest
10
inserts into the collar
18
. Affixed to the collar
18
is Detail
3
. Detail
3
forms an ear or anchor that includes a bolthole that allows for securement of Link
2
. Further, Link
1
is secured to Bracket
1
at the bolthole
16
located in the lower left hand portion of Bracket
1
. At this point, the handle
12
secures to Link
1
, and Link
1
secures to Bracket
1
. Link
1
secures to Bracket
1
through an upwardly extending pin
17
that includes a flattened end to allow Link
1
to properly fit over the pin
17
and to be held in place. A handle
12
for triggering the mechanism
14
is secured to the pin
17
with a set screw (not shown). Link
1
and Link
2
are secured at the pivot point
19
shown best in
FIG. 3
b
, and can pivot relative to each other about that point
19
. A pin
15
serves as a stop for extension of the footrest
10
.
FIG. 3
b
shows the linking mechanism
14
in a position that extends the footrest
10
. In this position handle
12
is downwardly located, and Link
1
and Link
2
are fully extended pushing Detail
3
, collar
18
, and the footrest
10
captured therein, into the extended position.
FIG. 4
shows the linking mechanism
14
in the retracted position. In order to move between the extended position and the retracted position, handle
12
is moved upward in an arc. This causes Link
1
and Link
2
to pivot about point
1
which forces Detail
3
and the attached collar
18
with the footrest captured therein, to move downward. This places the footrest
10
in a position below the seat of the chair, and out of the way of the user. As can be seen from the Figures, the collar
18
is secured to Bracket
1
at bolthole
16
, located in the upper left hand portion of Bracket
1
, in such a manner that the collar
18
can pivot relative to Bracket
1
. Additionally, Link
1
is secured to the bolt hole
16
, located in the lower left hand portion of Bracket
1
, in such a manner to allow Link
1
to pivot relative to Bracket
1
upon movement of handle
12
.
The mechanism
14
ensures that the footrest
10
remains in the extended position by positioning the stop pin
15
at a point such that the pivot point
19
between Link
1
and Link
2
extends past center. Thus, downward pressure on the extended footrest
10
will force Link
1
and Link
2
into pin
15
. The footrest
10
can be further supported in the extended and retracted positions through the use of a compression spring, such that if the footrest is not fully extended or retracted the spring will bias the footrest
10
into one or the other of the two positions.
The foregoing description and drawings merely explain and illustrate the invention, and the invention is not limited thereto. Those skilled in the art that have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention. Merely listing the steps of the method in a certain order does not constitute any limitation on the order of the steps of the method, or how they are contemplated and expected based on the application of ordinary skill.
