The footrest assembly includes a gear assembly, a first pedal and a second pedal. The first pedal and the second pedal move between an open configuration and a closed configuration, wherein in the open configuration, the first pedal and the second pedal form a footrest and in the closed configuration, the first pedal and the second pedal are moved toward one another to form a configuration that enables a user to easily exit the stylist chair. Also, the first pedal and the second pedal are coupled to the gear assembly so that when one of the first pedal and the second pedal moves, the other of the first pedal and the second pedal simultaneously moves.

## Background
FIELD
This application relates generally to a stylist chair and, more particularly, to an articulating footrest for a stylist chair.
BACKGROUND
Salon, stylist or barber's chairs are widely used by beauticians, stylists, barbers and other individuals for performing a service for a user seated in the chair. FIG. 1 illustrates a typical prior art stylist chair, which contains a chair 70′, a center bar 50′, and a footrest 10′. The footrest 10′ supports a user's feet while he or she is sitting in the chair 70′. However, the center bar 50′ and footrest 10′ together form a “T shape” that is unmovable. The shape and location of such a footrest 10′ can create a tripping hazard. For example, when disembarking from the chair, the user typically removes his/her feet from the footrest 10′ and sets each foot on the ground such that the individual's legs straddle the center bar 50′ and the feet are behind the footrest 10′. The individual must then spread his/her legs wider in order to step away from the chair 70′ without tripping on the footrest 10′. Older people, in particular, have greater difficulty maneuvering in such a manner. Thus, it would be desirable to provide an improved footrest assembly that can be easily manipulated so that it presents less of a tripping hazard and allows for a user to easily step away from a stylist chair.

It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended; any alterations and further modifications of the described or illustrated embodiments, and any further applications of the principles of the invention as illustrated therein, are contemplated as would normally occur to one skilled in the art to which the invention relates.
In the foregoing detailed description, the invention has been described with reference to specific embodiments. However, it can be appreciated that various modifications and changes can be made without departing from the scope of the invention.
FIGS. 2-10 illustrate a footrest assembly 10 according to a first embodiment. FIGS. 11-29 illustrate a footrest assembly 110 according to a second embodiment. In each embodiment, the footrest assembly includes a gear assembly, a first pedal and a second pedal. The first pedal and the second pedal move between an open configuration and a closed configuration. In the open configuration, the first pedal and the second pedal are moved away from one another to form a footrest. In the closed configuration, the first pedal and the second pedal are moved toward one another to form a configuration that enables a user to easily exit the stylist chair. Also, the gear assembly is a cooperating gear assembly, so that when one of the first pedal and the second pedal moves, the other of the first pedal and the second pedal simultaneously moves. Each the first embodiment and the second embodiment will now be described.
FIGS. 2-10 illustrate a footrest assembly 10 according to the first embodiment. The footrest assembly 10 can be coupled to a stylist chair 70 through a central bar 50, as shown in FIG. 2. Each the stylist chair 70 and central bar 50 can have any design or configuration known in the art. Likewise, the footrest assembly 10 can be attached to the central bar 50 using attachment mechanisms known in the art. The footrest assembly 10 has an open configuration and a closed configuration. In the open configuration, as shown in FIG. 3, the footrest assembly 10 forms a footrest that enables a user to rest his or her feet on when using the stylist chair 70. In the closed configuration, as shown in FIG. 4, the footrest assembly 10 closes enables a user to easily exit the stylist chair 70.
The footrest assembly 10 includes a first pedal 12a, a second pedal 12b and a gear assembly 14. The first pedal 12a and the second pedal 12b are each coupled to the gear assembly 14. The gear assembly 14 is a cooperating gear assembly that causes the first pedal 12a and the second pedal 12b to move simultaneously together and cooperate with one another. In other words, when one of the first pedal 12a or the second pedal 12b moves, the other of the first pedal 12a or the second pedal 12b simultaneously moves. In the first embodiment, the gear assembly 14 includes a first gear 14a and a second gear 14b. The first gear 14a is coupled to the first pedal 12a. Likewise, the second gear 14b is coupled to the second pedal 12b. The pedals 12a, 12b generally move forward and backward.
The footrest assembly 10 also includes an optional housing 24 that covers at least a portion of the gear assembly 14. The housing 24 can have a variety of different configurations. As shown in FIG. 5, the housing 24 includes a front guard 16 and a bottom plate 18. The front guard 16 has a shape (such as a horseshoe shape) that generally matches the shape of the bottom plate 18, so the front guard 16 can rest on top of or around the periphery of bottom plate 18. The bottom plate 18 also includes a hole 22. Each the first gear 14a and the second gear 14b is positioned on top of the bottom plate 18. A fastening device 26 (such as a screw) extends through the hole 22 and into a corresponding hole (not shown) on the bottom of the first gear 14a. Thus, as shown in FIG. 6, the fastening device 26 secures the bottom plate 18 to the first gear 14a. Referring back to FIG. 5, the front guard 16 also has two openings 28a, 28b through which the first pedal 12a and the second pedal 12b can extend through. The front guard 16 is positioned around the gear assembly 14 so that the first pedal 12a extends through the opening 18a and the second pedal 12b extends through the opening 26b. 
The central bar 50 is also secured to the footrest assembly 10. Referring to FIG. 7, the central bar 50 can be secured to the first gear 14a and the second gear 14b. For example, the first gear 14a has a top hole 20a and the second gear 14b has a top hole 20b. The central bar 50 also has holes 56a, 56b. The hole 56a is configured to align with hole 20a and the hole 56b is configured to align with hole 20b. A pair of screws 58a, 58b extend through holes 56a, 56b into holes 20a, 20b to secure the central bar 50 to the first gear 14a and the second gear 14b. Once the central bar 50 is secured to the first gear 14a and the second gear 14b, the central bar 50, together with the housing 24, hides at least a portion of the gear assembly 14.
The first gear 14a and the second gear 14b are coupled to one another in a cooperating fashion, so that when one gear moves, the other gear simultaneously moves. As best shown in FIG. 8, the first gear 14a includes a plurality of teeth 34a and the second gear 14b also includes a plurality of teeth 34b. The plurality of teeth 34a of the first gear 14a engages with the plurality of teeth 34b of the second gear 14b to cause the first gear 14a and the second gear 14b to cooperate with one another. The plurality of teeth 34a, 34b can have any desired configuration that allows the first gear 14a and the second gear 14b to engage with and cooperate with one another. In this first embodiment, the plurality of teeth 34a includes three peaks 46a and four grooves 48a adjacent the peaks 46a and the plurality of teeth 34b includes four peaks 46b and three grooves 48b adjacent the peaks 46b. The three peaks 46a of the first plurality of teeth 34 mate with the three grooves 48b of the second plurality of teeth 34b. Likewise, the four peaks 46b of the second plurality of teeth 34b mate with the four grooves 48a of the first plurality of teeth 34a. Of course, any number of peak and groove combinations can be present on the plurality of teeth 34a, 34b to enable the first gear 14a and the second gear 14b to engage with one another.
The pedals 12a, 12b cooperate with one another through the gears 14a, 14b. Specifically, the first gear plurality of teeth 34a engages with the second gear plurality of teeth 34b so that as one of the first gear 14a or the second gear 14b is turned, the engaging plurality of teeth 34a, 34b causes the other of the first gear 14a or the second gear 14b to simultaneously turn. Specifically, when a user moves the first pedal 12a rearward (towards the stylist chair), the first gear 14a turns clockwise. The engaging plurality of teeth 34a, 34b causes the second gear 14b to turn counterclockwise simultaneously, also causing the second pedal 12b to move rearward simultaneously. Likewise, when a user moves the first pedal 12a forward (away from the stylist chair), the first gear 14a turns counterclockwise. The engaging plurality of teeth 34a, 34b causes the second gear 14b to turn clockwise simultaneously, also causing the second gear 14b to move forward simultaneously.
In other words, when a user moves the second pedal 12b rearward, the second gear 114b turns counterclockwise. The engaging plurality of teeth 34a, 34b causes the first gear 14a to turn clockwise simultaneously, also causing the first pedal 12a to move rearward simultaneously. Likewise, when a user moves the second pedal 12b forward, the second gear 114b turns clockwise. The engaging plurality of teeth 34a, 34b causes the first gear 114a to turn counterclockwise simultaneously, also causing the first gear 14a to move forward simultaneously. Thus, the first pedal 12a and the second pedal 12b always move rearward and forward together and simultaneously.
Additionally, the gears 14a, 14b include stops that hold them in place in either the open configuration or the closed configuration. These stops are perhaps best illustrated in FIGS. 9 and 10. FIG. 9 shows the gears 14a, 14b (and thus the pedals 12a, 12b) in a closed configuration and FIG. 10 shows the gears 14a, 14b (and thus the pedals 12a, 12b) in an open configuration. The first gear 14a includes a proximal edge 30a and a distal edge 32a. Likewise, the second gear 14b includes a proximal edge 30b and a distal edge 32b. 
As best shown in FIG. 9, the proximal edge 30a of the first gear 14a abuts the proximal edge 30b of the second gear 14b to position the first pedal 12a and the second pedal 12b in the closed configuration. When the proximal edges 30a, 30b abut together, they form a proximal junction 40 or stop. In this closed configuration, the first pedal 12a and the second pedal 12b are moved forward and toward one another so that they are adjacent to or even in contact with one another. This closed configuration enables a user to easily exit the stylist chair.
As best shown in FIG. 10, the distal edge 32a of the first gear 14a abuts the distal edge 32b of the second gear 14b to position the first pedal 12a and the second pedal 12b in the open configuration. When the distal edges 32a, 32b abut together, they form a distal junction 42 or stop. In this open configuration, the first pedal 12a and the second pedal 12b are moved rearward and away from one another so that they extend outward as a footrest. This open configuration provides a footrest that enables a user to rest his or her feet on when using the stylist chair.
During use, a user simply moves the pedals 12a, 12b rearward and forward between the open configuration and the closed configuration. As shown in FIG. 9, when a user moves the either the first pedal 12a or the second pedal 12b rearward towards the closed configuration, the interlocking plurality of teeth 34a, 34b allow for the gears 14a, 14b to turn until their proximal edges 30a, 30b abut one another at the proximal junction 40. The proximal junction 40 therefore serves as a stop that holds the pedals 12a, 12b in the closed configuration. Likewise, as shown in FIG. 10, when a user moves the either the first pedal 12a or the second pedal 12b forward towards the open configuration, the interlocking plurality of teeth 34a, 34b allow for the gears 14a, 14b to turn until their distal edges 32a, 32b abut one another at the distal junction 42. The distal junction 42 therefore serves as a stop that holds the pedals 12a, 12b in the open configuration.
FIGS. 11-26 illustrate a footrest assembly 110 according to a second embodiment. FIG. 2 shows a stylist chair 170 having a footrest assembly 110. The footrest assembly 110 is coupled to the stylist chair 170 via the central bar 150. Each the stylist chair 170 and central bar 150 can have any design or configuration known in the art. Likewise, the footrest assembly 110 can be attached to the central bar 150 using attachment mechanisms known in the art.
Like the footrest assembly 10 of the first embodiment, the footrest assembly 110 of the second embodiment is also movable between an open configuration and a closed configuration. FIG. 12 shows the footrest assembly 110 in a closed configuration. In the closed configuration, the footrest assembly 110 closes and enables a user to easily exit the stylist chair 170. FIG. 13 shows the footrest assembly 110 in an open configuration. In the open configuration, the footrest assembly 110 forms a footrest that enables a user to rest his or her feet on when using the stylist chair 170. FIGS. 14 and 15 show the footrest assembly 110 in a configuration that is in between the closed configuration shown in FIG. 12 and the open configuration shown in FIG. 13.
Generally, the footrest assembly 110 includes a gear assembly 114, a first pedal 112a and a second pedal 112b. Like the first embodiment, the first pedal 112a and the second pedal 112b are coupled to the gear assembly 114 and the gear assembly 114 is a cooperating gear assembly that causes the first pedal 112a and the second pedal 112b to move simultaneously together. The gear assembly 114 also includes a first gear 114a and a second gear 114. The first gear 114a is coupled to the first pedal 112a and the second gear 114b is coupled to the second pedal 112b. The pedals 112a, 112b generally move upward and downward between the closed configuration shown in FIG. 12 and the open configuration shown in FIG. 13.
Referring to FIGS. 12 through 15, the footrest assembly 110 also includes an optional housing 116 that surrounds at least a portion of the gear assembly 114. The housing 116 can have a variety of different configurations. In the second embodiment, the housing 116 is a two-piece structure and includes a first section 116a and a second section 116b. The sections 116a, 116b are assembled together to form the housing 116 that surrounds at least a portion of the gear assembly 114. Of course, the housing 116 can alternatively include a three-piece structure, four-piece structure and the like. The housing 116 can include openings 180a, 180b, which receive tubular portions of the central bar 150. Of course, other attachment mechanisms to the central bar 150 can be used instead.
As shown in FIGS. 16 and 17, the gear assembly 114 includes a first gear 114a and a second gear 114b. Each the first gear 114a and the second gear 114b includes a generally circular body 132a, 132b having an outer perimeter or circumference 134a, 134b. In some embodiments, the first gear 114a and the second gear 114b are mirror images of one another, although this is by no means required. At least a portion of the outer circumference 134a, 134b defines a plurality of teeth. In the illustrated embodiment, the entire outer circumference 134a, 134b defines the plurality of teeth.
The plurality of teeth 134a, 134b can have any desired configuration that allows the first gear 14a and the second gear 14b to engage with and cooperate with one another. The plurality of teeth 134a, 134b generally includes alternating peaks 146a, 146b and grooves 148a, 148b. Each peak 146a peak on the first gear 114a has a size and shape that fits or mates within each groove 148b on the second gear 114b. Likewise, each peak 146b peak on the second gear 114b has a size and shape that fits or mates within each groove 148a on the first gear 114a. In the second embodiment, all of the peaks 146a, 146b are identical and all of the grooves 148a, 148b are identical, but this is by no means required. Any desired peak and groove configuration can be used to cause the plurality of teeth 134a, 134b to engage with each other.
The generally circular body 132a, 132b of each gear 114a, 114b also has an extending portion 138a, 138b that extends outward from the body 132a, 132b. The extending portion 138a, 138b also has a generally circular shape. In some embodiments, the extending portion 138a, 138b has the same size and shape of the generally circular body 132a, 132b but does not include the outer plurality of teeth 134a, 134b. Both the generally circular body 132a, 132b and the extending portion 138a, 138b include a central bore (not shown) that extends all the way through from a front of the circular body 132a, 132b to a rear of the extending portion 138a, 138b. 
An axle 136a, 136b extends through the central bore. The axle 136a, 136b has a generally circular body that is sized and shaped to extend through the central bore. More specifically, the axle 136a, 136b has a front end and a rear end, the front end being the portion that extends outward and frontward from the generally circular body 132a, 132b and the rear end being the portion that extends outward and rearward from the extending portion 136a, 136b. 
The first gear 114a is coupled to the first pedal 112a and the second gear 114b is coupled to the second pedal 112b. Referring to FIGS. 18 and 19, the pedal 112a, 112b includes a receiving hole 140a, 140b and a recess 142a, 142b. The receiving hole 140a, 140b extends through the recess 142a, 142b. In the second embodiment, the recess 142a, 142b is generally circular in shape and the receiving hole 140a, 140b has a shape that is smaller than the shape of the recess 142a, 142b. 
The axle 136a, 136b extends through the receiving hole 140a, 140b to secure the gear 114a, 114b to the pedal 112a, 112b. Generally, the gear 114a, 114b is inserted into the retaining hole 140a, 140b so that the rear end of the axle 136a, 136b extends through the retaining hole 140a, 140b. At the same time, the extending portion 138a, 138 fits nicely within the recesses 142a, 142b. As such, the recess 142a, 142b has a size and shape that matches the size and shape of the extending portion 136a, 136b so that the extending portion 136a, 136b can fit within the recessed portion 142a, 142b. This allows the pedals 112a, 112b to be coupled to the gears 114a, 114b. 
The pedals 112a, 112b cooperate with one another through the gears 114a, 114b. Specifically, the first gear plurality of teeth 134a engages with the second gear plurality of teeth 134b so that as one of the first gear 114a or the second gear 114b is turned, the engaging plurality of teeth 134a, 134b causes the other of the first gear 114a or the second gear 141b to simultaneously turn. Specifically, referring to FIGS. 20 through 22, when a user moves the first pedal 112a downward, the first gear 114a turns clockwise. The engaging plurality of teeth 134a, 134b causes the second gear 114b to turn counterclockwise simultaneously, also causing the second pedal 112b to move downward simultaneously. Likewise, when a user moves the first pedal 112a upward, the first gear 114a turns counterclockwise. The engaging plurality of teeth 134a, 134b causes the second gear 114b to turn clockwise simultaneously, also causing the second gear 114b to move upward simultaneously.
In other words, when a user moves the second pedal 112b downward, the second gear 114b turns counterclockwise. The engaging plurality of teeth 134a, 134b causes the first gear 114a to turn clockwise simultaneously, also causing the first pedal 112a to move downward simultaneously. Likewise, when a user moves the second pedal 112b upward, the second gear 114b turns clockwise. The engaging plurality of teeth 134a, 134b causes the first gear 114a to turn counterclockwise simultaneously, also causing the first gear 114a to move upward simultaneously. Thus, the first pedal 112a and the second pedal 112b always move upward and downward together and simultaneously.
With continued reference to FIGS. 20 through 22, the footrest assembly 110 also includes a biasing apparatus 182 that biases the footrest assembly 110 towards the closed configuration. The pedals 112a, 112b include top surfaces 124a, 124b and bottom surfaces 126a, 126b. The top surfaces 124a, 124b define a footrest surface. The bottom surface 126a of the first pedal 112a includes a recess 180 that houses the biasing apparatus 182. The recess 180 and the biasing apparatus 182 can have any desired shape or configuration that allows the biasing apparatus 182 to fit within and be retained by the recess 180. The biasing apparatus 182 can be a torsion spring that biases the first pedal 112a (and thus the second pedal 112b) upwards and towards the closed configuration shown in FIG. 20. In order to move the pedals 112a, 112b towards the open configuration shown in FIG. 22, a user must apply a generally downward force to one of the pedals 112a, 112b. This force goes against the biasing force of the biasing apparatus 182 to force the pedals 112a, 112b downward and towards the open configuration.
The footrest assembly 110 also includes a locking mechanism. Referring to FIGS. 23 and 24, the locking mechanism includes a lever 172 that locks and unlocks the pedals 112a, 112b in the open configuration. The lever 172 is coupled to the bottom surface 126a of the first pedal 112a. The lever 172 includes a front end 164 and a rear end 166. The frontend 164 includes a knob 190 for gripping by a user. The lever also includes a biasing apparatus 178 that biases the lever in a forward direction y. The biasing apparatus 178 can be a compression spring that pushes the lever forwardly in the direction y. The compression spring can have a size and shape that allows it to be positioned on the lever 172 so that it wraps around at least a portion of the front end 164. The knob 190 is also placed on the front end 164 so that it holds the compression spring in place on the front end 164. In some cases, the compression spring is secured to the knob 190 itself.
Referring to FIG. 25, the lever 172 also includes a bellow 174 that is positioned on the lever 172 so that it is in between the front end 164 and the rear end 166. The lever bellow 174 includes an engaging surface or shoulder 176. The bottom surface 126a of the first pedal 112a also includes a protrusion 184 that extends outward and downward from the bottom surface 126a. The protrusion 184 also includes an engaging surface or shoulder 186. The bellow engaging surface 176 is configured to slidably engage with the protrusion engaging surface 186. The surfaces 176, 186 can have any desired configuration that allows them to slidably engage with one another. In this second embodiment, the surfaces 176, 186 are slanted at angles that allow the surfaces 176, 186 to slide over one another. Typically, both surfaces 176, 186 will be slanted at the same angle. The protrusion 184 of the bottom surface 126a of the first pedal 112a also includes a receiving aperture 188 that is positioned above the engaging surface 186 and receives the bellow engaging surface 176. As such, the aperture 188 has a size and shape that allows for the bellow engaging surface 176 to insert thereinto. FIG. 26 best shows the receiving aperture 188 receiving the bellow engaging surface 176.
The overall operation of the footrest assembly 110 will now be described with reference to FIGS. 27 through 29. The default configuration of the footrest assembly 110 is the closed configuration shown in FIG. 27. Again, this is because the biasing apparatus 182 biases the first pedal 112a towards the closed configuration. When a user desires to use a footrest, he or she pushes downward on one of the pedals 112a, 112b. For example, a user may simply place a foot on a pedal 112a, 112b so that the weight of the foot forces the pedals 112a, 112b to move downward.
Referring to FIG. 28, as the first pedal 112a moves downward, the protrusion engaging surface 186 moves closer to the bellow engaging surface 176 until the surfaces 176, 186 contact one another. As the surfaces 176, 186 contact one another, the protrusion engaging surface 186 slides downward along the bellow engaging surface 176. This sliding engagement causes the bellow engaging surface 176 (and thus the lever 172) to move rearward against the biasing direction y.
The user continues to push downward on one of the pedals 112a, 112b (and the lever 172 continues to move rearward) until the bellow engaging surface 176 slides past the protrusion engaging surface 186 and reaches the receiving aperture 188. The bellow engaging surface 176 then snaps or otherwise locks into the receiving aperture 188, as shown in FIG. 29. The forward biasing of the lever 172 pushes the bellow engaging surface 176 into the receiving aperture 188 and thus locks the footrest assembly 110 in the open configuration. A user then uses the footrest assembly 110 to rest his or her feet while it is in this open configuration of FIG. 29.
When a user is done using the stylist chair and desires to exit the chair, he or she positions his or her hands on the lever knob 190 and pushes the lever 172 rearward against the forward biasing direction y. The lever is pushed rearward until the bellow engaging surface 176 moves out of and away from the receiving aperture 188. At this point, the biasing apparatus 182 of the first pedal 112a biases the pedals 112a, 112b upward and back the default closed configuration shown in FIG. 27. Thus, a user simply pushes the lever 172 rearward until the pedals 112a, 112b unlock from the open configuration of FIG. 29 and revert back to the closed configuration of FIG. 27.
