TECHNICAL FIELD
The present technology is related to a support apparatus and associated methods of using same. In particular, the present technology is related to a reconfigurable support apparatus for a user obtaining a tattoo and a user applying a tattoo.
BACKGROUND
The popularity of tattoos has increased and inspired refinement in tattoo equipment and the sophistication of tattoos themselves. A typical tattoo studio has a variety of tools to apply tattoos to clients. For example, a tattoo artist may have a tattoo chair, a table, an arm stand, a footrest, etc. All of these pieces of furniture take up space, yet may be required in order to properly apply tattoos.
The furniture used by tattoo artists is often not specifically designed to be used to apply tattoos, but rather, are used for other applications, such as medical or beauty salon applications. Thus, prolonged use of the furniture for tattooing may be uncomfortable for both the tattoo artist and the client. For example, many tattoo artists use massage tables to apply tattoos to a client's back, shoulders, or legs. Because massage tables are not designed for the ergonomic needs of a tattoo artist, they may cause discomfort or health problems for the artist.
Moreover, commonly used furniture in tattooing may not be able to place the client in a position that naturally stretches the area of the skin that is going to receive the tattoo. In order to receive a high-quality tattoo, the skin needs to be stretched; otherwise, the tattoo may be applied incorrectly (e.g., the tattoo may be disfigured). In order to compensate, a tattoo artist typically manually stretches and holds the client's skin while the tattoo is applied. This is uncomfortable for the tattoo artist, the client, or both. Additionally, the artist may not stretch the skin in a way that it would naturally stretch, resulting in distortion of the tattoo. Accordingly, there is a need for an apparatus that can be used to comfortably position a client for tattooing.
SUMMARY
An exemplary embodiment is a support apparatus for supporting a user, such as a client receiving a tattoo or a tattoo artist applying a tattoo on a client. The support apparatus can rest upon a support surface (e.g., a floor) and can be configured to ergonomically support a user's upper body, including the user's chest, arms, chin, or other body parts, to help prevent, reduce, or limit muscle fatigue (e.g., muscle fatigue in the user's arms, shoulders, back, etc.), discomfort, and/or pain. The apparatus can be configured such that a client can be placed in an ergonomic position, for example, a position that is comfortable for the client, the tattoo artist, or both. For example, the apparatus can be reconfigurable to adjust between different positions, such as a bed position (e.g., a horizontal arrangement), a chair position (e.g., an arrangement for supporting the client in a sitting position by articulating certain sections of the apparatus relative to the floor), a straddling configuration (e.g., an artist or client can straddle the apparatus), or other positions.
In some embodiments, during a tattoo session, the tattoo artist can move sections of the apparatus to desired locations to facilitate applying the tattoo. For example, a headrest can be reconfigured between a head support configuration and a chin support configuration. In another example, a footrest can be reconfigured between different heights. In some embodiments, the support apparatus can be manually reconfigured by, for example, operating one or more locking mechanisms, manually rotating components (e.g., arm rests, sections of the chest support, etc.), or the like. In some embodiments, the support apparatus can be motorized. For example, headrests, footrests, chest supports, armrests, and other features can be motorized to automatically position components at desired positions using a controller. In some embodiments, the support apparatus can be both manually and automatically reconfigurable. For example, a user can manually set parts to desired positions. The user can also reconfigure the support apparatus automatically based on preset configurations defined, for example, by the user, the manufacturer, or the like.
In some cases, the user can lean forward against a padded chest support of the support apparatus. The chest support allows unrestricted movement of the user's arms on the front side of the chest support. For example, the user's chest can rest comfortably against the back side of the chest support while the user performs various tasks on the front side. The support apparatus can further include armrests or other support devices for supporting the user's shoulders, arms, or the like. For example, the arm rests can be positioned to support the user's arms while the user rests against the chest support.
In at least one exemplary embodiment, an apparatus can include arm sections, leg sections, a seat section, and a back section, some of which can be coupled to a frame. Each section can comfortably support and articulate different parts of a client's body during a tattoo session. For example, the arm sections can be raised, lowered, or angled in order to place the arms of a client in positions to comfortably support the arms while one or more tattoos are applied.

DETAILED DESCRIPTION OF TECHNOLOGY
FIGS. 1 and 2 are isometric views of a chair or support apparatus 100 (“apparatus 100”) in a chair configuration and in a bed configuration, respectively, in accordance with embodiments of the present technology. The apparatus 100 can be configured such that a user can be placed in an ergonomic position, for example, a position that is comfortable for the user, the tattoo artist, or both. For example, the apparatus 100 can be reconfigurable to adjust between different positions, such as the chair configuration of FIG. 1 (e.g., an arrangement for supporting the user in a sitting position by articulating certain sections of the apparatus relative to the floor), the bed configuration of FIG. 2 (e.g., a horizontal arrangement), or other configurations (e.g., arranged at an angle between the chair and bed configurations). In some embodiments, the apparatus can be manually moved between different configurations. During a tattoo session, the tattoo artist can move (e.g., manually or robotically) different sections of the apparatus to desired locations to facilitate applying a tattoo. In motorized embodiments, the apparatus can be electrically driven between different configurations using, for example, a controller. The controller can be operated by the user and/or the tattoo artist.
The apparatus 100 can include supporting padded sections, including leg sections 202 and 204, arm sections 208 and 210, seat section 206, back section 212, and headrest 220 flush with seat section 206, together forming a generally flat surface for a user to lie on when in the bed configuration. The back section 212 can be configured to be straddled by the user receiving the tattoo. In exemplary embodiments, the back section 212 can be formed into a variety of shapes in order to support a user's back in the bed and chair configurations, and to allow the user to straddle it. In some embodiments, the back section 212 has a generally cobra-hood-shaped design. In this exemplary embodiment, a proximal portion of the back section 212 (i.e., closer to the seat section 206) can be narrower than a distal portion of the back section 212 (i.e., farther from the seat section 206) in order to define leg openings 602, 604 configured to receive a user's legs when the user is straddling the back section 212. The leg openings 602, 604 can be formed by removing different types of shapes from the back section 212 such as, for example, plano-concave, incurvation-shaped, generally rectangular, generally circular, generally oval, or generally square cuts, or cuts defined by a tapering from the proximal end of the back section 212 to the distal end. In at least one exemplary embodiment, the back section 212 could be generally “T” or “Y” shaped or cobra-hood shaped.
The back section 212 can be rotatably coupled to, for example, a rear portion of the seat section 206. The coupling that attaches the proximal portion of the back section 212 can be used to reconfigure the apparatus 100 from the chair configuration (FIG. 1) to the bed configuration (shown in FIG. 2). For example, a user could rotate the back section 212 from the position illustrated in FIG. 1 to the position illustrated in FIG. 2 by rotating the back section 212 from a position in which the back section 212 is generally perpendicular (e.g., ±5% of perpendicular, ±2% of perpendicular, ±1% of perpendicular, etc.) to the seat section 206 (i.e., generally parallel to the frontal plane) to a position in which the back section 212 is flush with the seat section 206 (i.e., parallel to the transverse plane of FIG. 2).
The back section 212 can also include a bacteria-resistant fabric cushion filled with foam padding or the like. As is described in more detail below, the back section 212 can be operatively coupled to a hinge (not shown) via one or more bolts, screws, pins, buttons, nails, adhesives, etc. In an exemplary embodiment, the hinge can be L-shaped. In another exemplary embodiment, the back section 212 can be coupled to the seat section 206 via a hinge. In this manner, the back section 212 can be supported by the seat section 206.
In this exemplary embodiment, a support frame 122 is generally covered with the various sections 204, 206, 208, 210, 212. In some embodiments, the frame 122 can be integrated into one or more of the sections 204, 206, 208, 210, 212. FIG. 2 shows a first axis 252 parallel to both the midsagittal plane and the transverse plane. The first axis 252 is formed by the midsagittal plane cutting through the apparatus and separates the right from left side. Also shown is a second axis 250 parallel to both the frontal plane and the transverse plane. The second axis 250 is formed by the frontal plane cutting through the apparatus and separates the front from the back.
The seat section 206 can include top and bottom portions separated by a plane generally parallel (e.g., ±5% of parallel, ±2% of parallel, etc.) to the transverse plane, forward and rearward portions separated by a plane parallel to the frontal plane, and left and right portions separated by a plane parallel to the midsagittal plane. The seat section 206 can include a bacteria-resistant fabric cushion filled with foam padding or the like. The bottom of the seat section 206 can be operatively coupled to the frame 122 via one or more bolts, screws, pins, buttons, nails, adhesives, etc.
The leg sections 202 and 204 can also be formed from bacteria-resistant fabric cushions filled with foam padding or the like. As described in more detail below, the leg sections 202 and 204 can be operatively coupled to the forward portion of the seat section 206 and/or to the frame 122. In an exemplary embodiment, the leg sections 202 and 204 can be coupled to rotatable assemblies that can independently rotate the leg sections 202 and 204 about an axis parallel to the second axis 250. The leg sections 202 and 204 can independently rotate from a position generally flush with the seat section 206 (e.g., FIG. 2) to a position generally perpendicular to the transverse plane (e.g., similar to the configuration shown in FIG. 1). In at least one embodiment, the leg sections 202 and 204 can also be rotated about a vertical axis (i.e., parallel to the frontal and midsagittal planes). In an exemplary embodiment, each leg section 202 and 204 can be independently rotated horizontally, vertically, or in other directions. In some embodiments, each leg section 202 and 204 has a one-piece design to provide a generally continuous support surface for the user's leg. The leg sections 202, 204 can be sufficiently long to extend along the user's leg, ankle, and foot. In some embodiments, the leg sections 202, 204 can be configured to couple to extenders or other components. This allows the apparatus 100 to receive additional components for flexibility in configuration.
As shown in FIG. 1, the leg openings 602, 604 can be configured to receive a majority of a user's legs when the user is straddling the back section 212. Leg supports 216, 218 of the seat section 206 can be positioned generally underneath the portions of the back section 212 defining the leg openings 602, 604. This allows the portions of the user's legs positioned immediately under the back section 212 to be supported comfortably by the leg supports 216, 218. The padded section 606 between the leg openings 602, 604 can be sufficiently narrow to allow the user to keep their legs generally parallel.
As shown in FIG. 2, the leg supports 216, 218 can be shaped to be compatible with the leg openings 602, 604 such that the back section 212 can be oriented generally parallel to the seat section 206 when the apparatus 100 is in the bed configuration. In an exemplary embodiment, the leg supports 216 and 218 can have a shape similar to the shape of the leg openings 602, 604 or can be cut out of the back section 212. For example, if the leg openings 602, 604 are square-like, the leg supports 216, 218 can be formed to be square-like. If the leg openings 602, 604 are plano-concave shaped, leg supports 216 and 218 can be formed to be plano-convex shaped. As shown in FIG. 2, the leg supports 216, 218 do not need to completely fill the leg openings 602, 604. The leg supports 216 and 218, for example, may only fill enough of the openings 602, 604 so that a user can lie flat on the apparatus 100 in the bed configuration. One or more footrest can be positioned directly below the ends of the leg supports 216 and 218 and are as discussed in connection with FIGS. 12A-15B.
The apparatus 100 can include motorized components for positioning various components. By way of example, the apparatus 100 can include a chest support assembly and motorized joints coupled to one or more of the various section 202, 204, 206, 208, 210, 212. The motorized joints can include one or more drive motors, solenoids, or other electronic components (e.g., sensors) and can robotically adjust the configuration of the apparatus 100. The apparatus 100 can include a controller that includes one or more memories, processors, processing units, input devices, keypads, switches, remotes, displays, screens, or combinations thereof. The controller can be in communication with components via wired connections, wireless connections, or both. The controller can be in communication with literary components via wired and/or wireless connections. The controller can be used to move (e.g., raise, lower, rotate, etc.), expand/contract, or otherwise alter a component. The apparatus 100 can receive power from an external power source, such as an AC outlet. In other embodiments, the apparatus 100 can have an internal power source, such as one or more batteries (e.g., rechargeable batteries), allowing the apparatus 100 to be used at a wide range of locations that may not have available power outlets. The power source can also used to power accessories, such as lights, tattoo gun, pumps, or the like.
The apparatus 100 can include one or more features, systems, devices, materials, methods, and techniques described in U.S. application Ser. No. 16/865,784, U.S. application Ser. No. 15/727,896, U.S. application Ser. No. 15/004,837, U.S. application Ser. No. 14/164,035, and U.S. application Ser. No. 12/876,953, all of which are hereby incorporated by reference in their entireties. The features, configurations, and common functionalities of the apparatus 100 can be selected based on the tattooing to be performed. Additionally, the apparatus 100 can be part of embodiments and/or include features discussed in connection with FIGS. 3-21. For example, the headrest 220 of FIGS. 1 and 2 can be replaced with, or in the form of, the headrest discussed in connection with FIGS. 6-15B and can include, or be used with, hinges discussed in connection with FIGS. 17-21. By way of another example, the apparatus 100 can include one or more footrests. By way of yet another example, the apparatus 100 can include features (e.g., actuator assemblies, controllers, control module, etc.) discussed in connection with FIGS. 3-5.
FIG. 3 is an enlarged rear view of a chair or support apparatus 300 (“apparatus 300”) with an actuator assembly 310 in accordance with embodiments of the present technology. FIG. 4 is an enlarged rear view of the apparatus 300 with an actuator cover 330. In the illustrated embodiment of FIG. 3, the actuator assembly 310 is coupled to the back section 212 and the seat section 206. The actuator assembly 310 can be operable to move the back section 212 between configurations (e.g., chair and bed configurations). The actuator assembly 310 can include one or more input devices (e.g., switches, toggles, etc.), one or more pistons (e.g., hydraulic pistons, pneumatic pistons, linear slides), one or more actuators, a controller, a power source (e.g., a rechargeable power source, batteries, etc.), or combinations thereof.
The apparatus 300 can also include a power/control module 340 (“control module 340”) operatively connected to the actuator assembly 310. The control module 340 can include a power strip 342, connection 344 with the actuator assembly 310, a power plug 350, and control inputs 360. The power strip 342 can include one or more plugs, ports (e.g., USB port, micro-USB port, etc.), and other electrical components. The number and configuration of the plugs can be selected based on the number of electrical components to be powered via the module 340. The control inputs 360 can include, without limitation, one or more dials, input pads, switches (e.g., illustrated reversing rocker switch), and other components for controlling operation of the actuator assembly 310, the apparatus 300, components powered by the apparatus 300, or the like. In some embodiments, the control module 340 is powered by connecting to an external power supply, such as an AC outlet. In other embodiments, the control module 340 can include one or more power sources, such as rechargeable batteries.
FIG. 4 is an enlarged rear view of components of the apparatus 300 with an actuator cover 330. The actuator cover 330 can cover and protect the actuator assembly 310. The actuator cover 330 can be removed to access internal components of the actuator assembly 310 for maintenance, cleaning, or the like. In some embodiments, the back section 212 includes a handle 370 for conveniently moving the apparatus 300 to different positions or configurations. Additionally, the handle 370 can be positioned above the leg openings 602, 604 to provide a convenient armrest for a user straddling the back section 212. The handle 370 can have a length 213 that is longer than each of the widths 605, 607 of the respective leg openings 604, 602, the combined widths 605, 607, and/or a width 609 of the straddlable portion 611. The handle 370 can hold the user's arms spaced apart from the user's legs for applying tattoos to the user's legs (e.g., front of the user's thighs). The handle 370 can include padding for comfort. In some embodiments, the handle 370 is positioned generally above the leg openings 602, 604 and/or user's thighs positioned in the openings 602, 604. In other embodiments, the handle 370 can be positioned at other locations and can include an adjuster (e.g., a motorized or manual adjuster) for adjusting the handle height and/or orientation (e.g., tilted orientation, horizontal orientation, etc.).
FIG. 5 is a side view of the actuator assembly 310 in a generally flat of bed configuration. The actuator assembly 310 (shown without a cover) can be generally parallel to the back section 212 and the seat section 206. The control module 340 can be positioned to avoid interference with positioning the user's body. For example, the control module 340 can be positioned directly underneath the bottom of the seat section 206 as illustrated. The handle 370 can be padded and can extend downwardly past the actuator assembly 310 so that the handle 370 serves as a stop. For example, the handle 370 can contact an object below the back section 212 to prevent contact between the actuator assembly 310 and the object. In some embodiments, a ratio of a protruding distance 383 of the handle 370 to a protruding distance 385 of the actuator assembly 310 (or cover 330 of FIG. 4) is equal to or greater than 1.5, 2, 3, 4, or 5. The ratio of protruding distances and configurations of the actuator assembly 310 and handle 370 can be selected based on the objects in the surrounding environment.
FIG. 6 is a front view of a back section 620 with an integrated headrest 640 in embodiments of the present technology. The headrest 640 can be a split headrest include a movable upper portion 610 and a lower portion 612. The position of the interface 650 between the upper portion 610 and the lower portion 612 can be selected based on the size of the user. The headrest 640 can be moved upwardly or downwardly to accommodate the user's body, as discussed in connection with FIG. 10.
The headrest 640 can include an optional opening 670 for placement of the user's face and/or the back of the user's head. The opening 670 can have a generally circular shape, oval shape, elliptical shape, teardrop shape, or other suitable shape for receiving at least a portion of the user's head. The opening 670 can be generally centered above a straddling portion 621 of the back section 212. This aligns the user's head with the support apparatus 300 for a comfortable posture.
The headrest 640 can have a generally continuous head-supporting edge 672 surrounding the opening 670. The head-supporting edge 672 can comfortably support the user's head. When the support apparatus 300 is in a bed configuration, the opening 670 can receive the back of the user's head while the user's back is against the back section 212. The opening 670 can receive the front of the user's head while the user straddles the back section 212. When the support apparatus 300 is in a bed configuration, the opening 670 can receive the user's face when the user lays face down. The opening 670 can receive the back of the user's head when the user lays face up. When the support apparatus 300 is in a chair configuration and the user straddles the back section 212 (e.g., the user's legs are positioned in openings 602, 604), the support apparatus 300 can support the user's chin. For example, a U-shaped, ergonomic chin rest channel 673 can be uncovered when the upper portion 610 is rotated rearwardly (e.g., away from an occupant of apparatus 300), and the user's chin can be positioned in the chin rest channel 673. The size, shape, configuration, and position of the opening 670 (including the chin rest channel 673) can be selected based on characteristics of the occupant. For example, the chin rest channel 673 can have a narrow form factor to provide a closer fit to support the user's chin, or can have a wide form factor to provide a loose fit and to support a wider range of users. A height of the U-shaped chin rest channel 673 can also be selected based on the desired support, such as by having the lower portion 612 cover or not cover the user's ears while the user's chin is positioned in the chin rest channel 673.
FIGS. 7 and 8 are side views of the headrest 640 in a head support configuration and in a chin support configuration, respectively. The headrest 640 is movable between multiple positions. FIG. 7 shows the headrest 640 at an upright, raised position in which the upper portion 610 extends across the chin support channel 673 (FIG. 6) and FIG. 8 shows the headrest 640 at lowered position.
Referring to FIG. 7, the upper portion 610 is rotatably coupled to the lower portion 612 by, for example, one or more hinges 618, flexible connectors, or other components for permanently coupling together the upper portion 610 and the lower portion 612. The lower portion 612 can include one or more first couplers 680, and the upper portion 610 can include one or more second couplers 682. The first and second couplers 680, 682 can comprise one or more magnets embedded (as shown for the second couplers 682) or attached to the surface (as shown for the first couplers 680). In some embodiments, both the first and second couplers 680, 682 are embedded in the headrest for an aesthetically pleasant appearance. The coupler 682 can be a magnet and the coupler 680 can be, for example, a magnet, a ferrous material, or the like. In some embodiments, the couplers 682, 680 can be coupled together using one or more fields, such as electromagnetic fields. In some embodiments, the first and second couplers 680, 682 can comprise other coupling features, such as Velcro, snap-ins, pins (e.g., lockable pins), retainers, buckles, etc. In some embodiments, the hinge 618 can include a locking mechanism to lock the headrest 640. For example, the hinge 618 can have a locking pin that can be removed to move the headrest 640. The locking pin can be inserted into the hinge to lock the headrest 640 at a set position. U.S. Pat. Nos. 8,651,569 and 9,375,088 disclose lockable hinges that can be incorporated into or coupled to the headrest 640, and some example hinges are discussed in connection with FIGS. 17-21.
The headrest 640 can have a forward-facing surface 661 formed by the upper and lower portions 610, 612. Referring to FIG. 7, the upper portion 610 can be aligned with the lower portion 612 and form a gapless interface 650. The upper and lower portions 610, 612 can define the generally continuous surface 661. In some embodiments, the upper portion 610 has a forward-facing surface 663 that is generally flush with or positioned along the same plane as the front surface 665 of the lower portion 612. The position and sizes of the surfaces 663, 665 can be selected based on the desired user support. The upper portion 610 can extend across and cover the entire length or depth D of the chin rest channel 673. For example, the upper portion 610 can extend across at least 90%, 95%, 98%, or 100% of the channel.
As shown in FIG. 8, the upper portion 610 can be rotated about the hinge 618 by approximately 180 degrees to interface with a rear side of the chin rest 612. This allows a user straddling the back section 620 to place their chin on the chin support 612. The chin rest 612 can be spaced apart from handle 670 to allow the user to rest their arms on the handle 670, which may be padded. The first and second couplers 680, 682 can removably attach to each other to keep the upper portion 610 in the rotated configuration shown in FIG. 8 (e.g., via magnetism, Velcro attachment, etc.). In some embodiments, the hinge 618 can be a locking hinge that can be locked to keep the headrest 640 in a desired configuration (e.g., the head support configuration of FIG. 7, the chin support configuration of FIG. 8) and unlocked to move the headrest 640 between various configurations. The first and second couplers 680, 682 and/or the locking hinge can be particularly beneficial when the apparatus 300 is in a bed configuration.
FIGS. 9 and 10 are front views of a back section 712 in a retracted or lowered position and in an extended or raised position, respectively. The description of the back sections discussed in connection with FIGS. 1-8 applies equally to the back section 712 unless indicated otherwise.
Referring to FIG. 9, the back section 712 can include an upper portion 714 and a lower portion 716. An adjustment assembly 720 can allow the upper portion 714 to be moved upwardly away from the lower portion 716, as shown in FIG. 10. This allows a user to adjust the height of the chin rest 612 relative to a seat section (not shown). The adjustability can be selected based on the ranges of sizes for occupants of the apparatus. In some embodiments, the adjustment assembly 720 can comprise rods that a person can manually raise or lower the upper portion 714 along. In some embodiments, the adjustment assembly 720 can comprise actuators that can be controlled via a controller, manual locking elements, pins, etc. In some embodiments, padding or blocks can be positioned on the seat section of the apparatus to elevate the user straddling the back section 712, allowing for further customization for desired comfort.
Referring now to FIG. 10, the user's chin can rest on a U-shaped chin-rest channel 713 while the user's forehead and upper face remain uncovered. The chin-rest channel 713 can help hold the user's head stationary to minimize or limit body movement and can be configured to contact the user's submental region, upper neck, cheeks, and/or lower face.
