Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 394,061, filed on August 1, 2022, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] The present technology relates to support devices and associated methods of using the support devices. In particular, the present technology relates to a reconfigurable support device for a user obtaining a tattoo and a user applying a tattoo. Background Art

[0004] The popularity of tattoos has increased and has inspired improvements in tattoo equipment and the sophistication of the tattoos themselves. A typical tattoo studio has a variety of tools to apply a tattoo to a client. For example, a tattoo artist may have a tattoo chair, table, arm rest, footrest, etc. All of these furniture pieces take up space, but they may be necessary in order to properly apply a tattoo.

[0005] The furniture used by tattoo artists is usually not designed specifically for applying tattoos, but is used for other applications, such as medical or beauty salon applications. Therefore, using these furniture for tattooing for a long time may be uncomfortable for both the tattoo artist and the client. For example, many tattoo artists use massage tables to apply tattoos to the back, shoulders or legs of clients. Because massage tables are not designed for the ergonomic needs of tattoo artists, they may cause discomfort or health problems for the tattoo artist.

[0006] Furthermore, the furniture commonly used when tattooing may not position the client in a position that naturally stretches the area of ​​skin that will receive the tattoo. In order to obtain a high-quality tattoo, the skin needs to be stretched; otherwise, the tattoo may be incorrectly applied (e.g., the tattoo may be ruined). To compensate for this, tattoo artists typically manually stretch and hold the client's skin while applying the tattoo. This can be uncomfortable for the tattoo artist, the client, or both. Additionally, the tattoo artist may not be able to stretch the skin in a way that the skin would naturally stretch, resulting in deformation of the tattoo. Therefore, there is a need for a device that can be used to comfortably position a client for tattooing. Summary of the invention

[0007] An exemplary embodiment is a support device for supporting a user, such as a client receiving a tattoo or a tattoo artist applying a tattoo on a client. The support device can be placed on a support surface (e.g., a floor) and can be configured to support the user's upper body, including the user's chest, arms, chin, or other body parts, in an ergonomic manner 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 device can be configured so that the client can be placed in an ergonomic position, such as a comfortable position for the client, the tattoo artist, or both. For example, the device can be reconfigured to be adjusted between different positions, such as a bed position (e.g., a horizontal arrangement), a chair position (e.g., an arrangement for supporting a client in a seated position by articulating certain sections of the device relative to the floor), a straddle configuration (e.g., a tattoo artist or client can straddle the device), or other positions.

[0008] In some embodiments, during the tattoo process, the tattoo artist can move sections of the device to a desired position to facilitate the application of the tattoo. For example, the headrest can be reconfigured between a head support configuration and a chin support configuration. In another example, the footrest can be reconfigured between different heights. In some embodiments, the support device can be manually reconfigured by, for example, operating one or more locking mechanisms, manually rotating a component (e.g., an armrest, a section of a chest support, etc.). In some embodiments, the support device can be motorized. For example, the headrest, footrest, chest support, armrests, and other features can be motorized to automatically position the component at a desired position using a controller. In some embodiments, the support device can be manually reconfigured and automatically reconfigured. For example, a user can manually set a component to a desired position. The user can also automatically reconfigure the support device based on a preset configuration defined, for example, by a user, a manufacturer, etc.

[0009] In some cases, the user can lean forward against a padded chest support of the support device. The chest support allows the user's arms to move unrestricted 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 device can also include armrests or other support devices for supporting the user's shoulders, arms, etc. For example, the armrests can be positioned to support the user's arms when the user rests on the chest support.

[0010] In at least one exemplary embodiment, the device may include arm sections, leg sections, a seat section, and a back section, some of which may be coupled to a frame. Each section may comfortably support and engage a different part of a client's body during a tattooing procedure. For example, the arm section may be raised, lowered, or angled to place a client's arm in a position that comfortably supports the arm while one or more tattoos are applied.

[0028] Figure 1 and Figure 2 Isometric views of a chair or support device 100 ("device 100") in a chair configuration and a bed configuration, respectively, according to embodiments of the present technology. Device 100 can be configured so that a user can be placed in an ergonomic position, such as a position that is comfortable for the user, the tattoo artist, or both. For example, device 100 can be reconfigured to be used in different positions, such as Figure 1 a chair configuration (e.g., an arrangement for supporting a user in a seated position by articulating certain sections of the device relative to the floor), Figure 2 The device can be adjusted between a bed configuration (e.g., a horizontal arrangement) or other configurations (e.g., arranged at an angle between a chair configuration and a bed configuration). In some embodiments, the device can be manually moved between different configurations. During the tattoo process, the tattoo artist can move different sections of the device (e.g., manually or automatically) to the desired position to facilitate the application of the tattoo. In a motorized embodiment, the device 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.

[0029] The device 100 may include a support cushion section including leg sections 202 and 204, arm sections 208 and 210, a seat section 206, a back section 212, and a headrest 220 that is flush with the seat section 206 when in the bed configuration to form a generally flat surface for a user to lie on. The back section 212 may be configured to be straddled by a tattooed user. In an exemplary embodiment, the back section 212 may be formed into a variety of shapes to support the user's back and allow the user to straddle the back section 212 in the bed configuration and the chair configuration. In some embodiments, the back section 212 has a generally cobra-shaped design. In this exemplary embodiment, the proximal portion of the back section 212 (i.e., closer to the seat section 206) can be narrower than the distal portion of the back section 212 (i.e., farther from the seat section 206) so as to define leg openings 602, 604 that are configured to receive the legs of a user when the user sits astride 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, a flat concave, inward curved, generally rectangular, generally circular, generally oval, or generally square cutout, or a cutout defined by tapering from the proximal end to the distal end of the back section 212. In at least one exemplary embodiment, the back section 212 can be generally "T"-shaped or "Y"-shaped or cobra-shaped.

[0030] The back section 212 can be rotatably coupled to, for example, a rear portion of the seat section 206. A coupling member that attaches the proximal portion of the back section 212 can be used to move the apparatus 100 from a chair configuration ( Figure 1 ) is reconfigured into a bed configuration (in Figure 2 ). For example, the user may rotate the back section 212 from a position where the back section 212 is substantially perpendicular (e.g., ±5% of perpendicularity, ±2% of perpendicularity, ±1% of perpendicularity, etc.) to the seat section 206 (i.e., substantially parallel to the front plane) to a position where the back section 212 is flush with the seat section 206 (i.e., parallel to the front plane). Figure 2 to move the back section 212 from Figure 1 Rotate the position shown in the figure to Figure 2 The location shown in the figure.

[0031] The back section 212 may also include an antimicrobial fabric cushion filled with foam padding or the like. As described in more detail below, the back section 212 may be operatively coupled to a hinge (not shown) via one or more bolts, screws, pins, buttons, nails, adhesives, or the like. In an exemplary embodiment, the hinge may be L-shaped. In another exemplary embodiment, the back section 212 may be coupled to the seat section 206 via a hinge. In this manner, the back section 212 may be supported by the seat section 206.

[0032] In this exemplary embodiment, the support frame 122 is generally covered with each section 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. Figure 2 A first axis 252 is shown that is parallel to both the mid-sagittal plane and the transverse plane. The first axis 252 is formed by the mid-sagittal plane cutting through the device and separates the right side from the left side. A second axis 250 is also shown that is parallel to both the frontal plane and the transverse plane. The second axis 250 is formed by the frontal plane cutting through the device and separates the front from the back.

[0033] The seat section 206 may include a top portion and a bottom portion separated by a plane that is substantially parallel to the transverse plane (e.g., ±5% parallelism, ±2% parallelism, etc.), a front portion and a rear portion separated by a plane parallel to the frontal plane, and a left portion and a right portion separated by a plane parallel to the mid-sagittal plane. The seat section 206 may include an antimicrobial fabric cushion filled with foam padding, etc. The bottom of the seat section 206 may be operatively coupled to the frame 122 via one or more bolts, screws, pins, buttons, nails, adhesives, etc.

[0034] The leg sections 202 and 204 may also be formed of an antimicrobial fabric cushion filled with foam padding or the like. As described in more detail below, the leg sections 202 and 204 may be operatively coupled to a front portion of the seat section 206 and / or the frame 122. In an exemplary embodiment, the leg sections 202 and 204 may be coupled to a rotatable assembly that allows the leg sections 202 and 204 to independently rotate about an axis parallel to the second axis 250. The leg sections 202 and 204 may be rotated from a position substantially flush with the seat section 206 (e.g., Figure 2 ) are independently rotated to a position approximately perpendicular to the transverse plane (e.g., similar to Figure 1). In at least one embodiment, the leg segments 202 and 204 can also rotate about a vertical axis (i.e., parallel to the frontal plane and the mid-sagittal plane). In an exemplary embodiment, each leg segment 202 and 204 can rotate independently horizontally, vertically, or in other directions. In some embodiments, each leg segment 202 and 204 has a one-piece design to provide a substantially continuous support surface for the user's legs. The leg segments 202, 204 can be long enough to extend along the user's legs, ankles, and feet. In some embodiments, the leg segments 202, 204 can be configured to be connected to an extender or other component. This allows the device 100 to accommodate additional components to have flexibility in configuration.

[0035] like Figure 1 , the leg openings 602, 604 can be configured to receive a majority of the user's legs when the user straddles the back section 212. The leg supports 216, 218 of the seat section 206 can be positioned generally below the portion of the back section 212 that defines the leg openings 602, 604. This allows the portion of the user's legs that is positioned directly below the back section 212 to be comfortably supported by the leg supports 216, 218. The pad section 606 between the leg openings 602, 604 can be narrow enough to allow the user to keep their legs generally parallel.

[0036] like Figure 2 As shown in , the leg supports 216, 218 can be shaped to be compatible with the leg openings 602, 604 so 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, the leg supports 216, 218 can be formed as square. If the leg openings 602, 604 are plano-concave, the leg supports 216 and 218 can be formed as plano-convex. As shown in FIG. Figure 2 As shown in FIG. 1 , the leg supports 216, 218 need not completely fill the leg openings 602, 604. For example, the leg supports 216 and 218 may only sufficiently fill the openings 602, 604 so that a user can lie flat on the device 100 in the bed configuration. One or more footrests may be positioned just below the ends of the leg supports 216 and 218, and as in combination FIG. 12A to FIG. 15B discussed.

[0037] The device 100 may include motorized components for positioning various components. By way of example, the device 100 may include a chest support assembly and a motorized joint connected to one or more of the sections 202, 204, 206, 208, 210, 212. The motorized joint may include one or more drive motors, solenoids, or other electronic components (e.g., sensors), and may automatically adjust the configuration of the device 100. The device 100 may include a controller including one or more memories, processors, processing units, input devices, keyboards, switches, remote controls, displays, screens, or combinations thereof. The controller may communicate with the components via a wired connection, a wireless connection, or both. The controller may communicate with the textual components via a wired connection and / or a wireless connection. The controller may be used to move the components (e.g., raise, lower, rotate, etc.), extend / retract, or otherwise change the components. The device 100 may receive power from an external power source, such as an AC outlet. In other embodiments, the device 100 may have an internal power source, such as one or more batteries (e.g., rechargeable batteries), to allow the device 100 to be used in a wide range of locations that may not have available power outlets. The power source may also be used to power accessories such as lights, tattoo guns, pumps, etc.

[0038] Device 100 may include one or more features, systems, devices, materials, methods, and techniques described in U.S. Application Nos. 16 / 865,784, 15 / 727,896, 15 / 004,837, 14 / 164,035, and 12 / 876,953, all of which are incorporated herein by reference in their entirety. Features, configurations, and common functions of device 100 may be selected based on the tattoo to be performed. Additionally, device 100 may be part of an embodiment and / or may include a combination of Figures 3 to 21 The characteristic in question. For example, Figure 1 and Figure 2 The headrest 220 can be combined with Figures 6 to 15B The headrest in question replaces or can be combined with Figures 6 to 15B The headrest in question may include a combination of Figures 17 to 21 The hinge discussed above may be used with or in conjunction with the hinge discussed above. By way of another example, the device 100 may include one or more footrests. By way of yet another example, the device 100 may include a Figures 3 to 5 The features discussed (eg, actuator assembly, controller, control module, etc.).

[0039] Figure 3is an enlarged rear view of a chair or support device 300 ("device 300") having an actuator assembly 310 in accordance with an embodiment of the present technology. Figure 4 is an enlarged rear view of the device 300 with the actuator cover 330. Figure 3 In the illustrated embodiment, the actuator assembly 310 is coupled to the back section 212 and the seat section 206. The actuator assembly 310 is operable to move the back section 212 between various configurations (e.g., a chair configuration and a bed configuration). The actuator assembly 310 may include one or more input devices (e.g., switches, toggle keys, 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, a battery, etc.), or a combination thereof.

[0040] The device 300 may also include a power / control module 340 ("control module 340") operatively connected to the actuator assembly 310. The control module 340 may include a power strip 342, a connection 344 to the actuator assembly 310, a power plug 350, and a control input device 360. The power strip 342 may include one or more plugs, ports (e.g., USB ports, micro USB ports, etc.), and other electrical components. The number and configuration of the plugs may be selected based on the number of electrical components to be powered via the module 340. The control input device 360 ​​may include, but is not limited to, one or more dials, input pads, switches (e.g., the illustrated reverse rocker switch), and other components for controlling the operation of the actuator assembly 310, the device 300, components powered by the device 300, and 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 may include one or more power sources, such as a rechargeable battery.

[0041] Figure 43 is an enlarged rear view of components of the device 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 the internal components of the actuator assembly 310 for maintenance, cleaning, etc. In some embodiments, the back section 212 includes a handle 370 for conveniently moving the device 300 to different positions or configurations. In addition, 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 length 213 of the handle 370 can be longer than each of the widths 605, 607 of the corresponding leg openings 604, 602, the combination of the widths 605, 607, and / or the width 609 of the straddleable portion 611. The handle 370 can keep the user's arms spaced apart from the user's legs to apply a tattoo to the user's legs (e.g., the front of the user's thigh). For comfort, the handle 370 can include padding. In some embodiments, the handle 370 is positioned generally above the leg openings 602, 604 and / or the user's thigh 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 adjuster or a manual adjuster) for adjusting the height and / or orientation (e.g., an inclined orientation, a horizontal orientation, etc.) of the handle.

[0042] Figure 5 is a side view of the actuator assembly 310 in a generally flat 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 interfering with the positioning of the user's body. For example, as illustrated, the control module 340 can be positioned directly below the bottom of the seat section 206. The handle 370 can be padded and can extend downwardly beyond the actuator assembly 310 so that the handle 370 acts 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, the protrusion distance 383 of the handle 370 is aligned with the actuator assembly 310 (or Figure 4 The ratio of the protrusion distance 385 of the cover 330) is equal to or greater than 1.5, 2, 3, 4, or 5. The ratio of the protrusion distances of the actuator assembly 310 and the handle 370 and the configuration of the actuator assembly 310 and the handle 370 can be selected based on objects in the surrounding environment.

[0043] Figure 66 is a front view of a back section 620 with an integrated headrest 640 in an embodiment of the present technology. The headrest 640 can be a separate headrest including a movable upper portion 610 and a lower portion 612. The position of the joint 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 up or down to accommodate the user's body, such as in combination with Fig.10 discussed.

[0044] The headrest 640 may include an optional opening 670 for placing the back of the user's face and / or the user's head. The opening 670 may have a generally circular shape, an oval shape, an elliptical shape, a teardrop shape, or other suitable shape for receiving at least a portion of the user's head. The opening 670 may be generally centered over the straddling portion 621 of the back section 212. This will align the user's head with the support device 300 for a comfortable posture.

[0045] The headrest 640 can have a substantially continuous head support edge 672 surrounding the opening 670. The head support edge 672 can comfortably support the user's head. When the support device 300 is in the bed configuration, the opening 670 can receive the back of the user's head when the user's back is against the back section 212. When the user sits astride the back section 212, the opening 670 can receive the front of the user's head. When the support device 300 is in the bed configuration, when the user lies face down, the opening 670 can receive the user's face. When the user lies face up, the opening 670 can receive the back of the user's head. When the support device 300 is in the chair configuration and the user sits astride the back section 212 (e.g., the user's legs are positioned in the openings 602, 604), the support device 300 can support the user's chin. For example, when the upper portion 610 is rotated rearward (e.g., away from an occupant of the device 300), the U-shaped ergonomic chin rest channel 673 can be uncovered 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 the characteristics of the occupant. For example, the chin rest channel 673 can have a narrower form factor to provide a tight fit to support the user's chin, or can have a wider form factor to provide a loose fit and support a wider range of users. The 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 when the user's chin is positioned in the chin rest channel 673.

[0046] Figure 7 and Figure 86. Side views of the headrest 640 in a head support configuration and a chin support configuration, respectively. The headrest 640 is movable between a plurality of positions. Figure 7 The upper portion 610 is shown extending across the chin rest channel 673 ( Figure 6 ) of the headrest 640 in an upright raised position, and Figure 8 The head restraint 640 is shown in a lowered position.

[0047] Reference Figure 7 , the upper part 610 is rotatably connected to the lower part 612 by, for example, one or more hinges 618, flexible connectors, or other components for permanently connecting the upper part 610 and the lower part 612 together. The lower part 612 may include one or more first couplers 680, and the upper part 610 may include one or more second couplers 682. The first coupler 680 and the second coupler 682 may include one or more magnets embedded (as shown for the second coupler 682) or attached to the surface (as shown for the first coupler 680). In some embodiments, both the first coupler 680 and the second coupler 682 are embedded in the headrest to have an aesthetically pleasing appearance. The coupler 682 may be a magnet, and the coupler 680 may be, for example, a magnet, a ferrous material, etc. In some embodiments, the couplers 682, 680 may be connected together using one or more fields, such as an electromagnetic field. In some embodiments, the first connector 680 and the second connector 682 can include other coupling features, such as Velcro, snaps, 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 allow the headrest 640 to move. The locking pin can be inserted into the hinge to lock the headrest 640 in a set position. U.S. Patent Nos. 8,651,569 and 9,375,088 disclose lockable hinges that can be incorporated into or coupled to the headrest 640, and in combination Figures 17 to 21 Some example hinges are discussed.

[0048] The headrest 640 may have a forward facing surface 661 formed by the upper portion 610 and the lower portion 612. Figure 7, the upper portion 610 can be aligned with the lower portion 612 and form a gapless joint 650. The upper portion 610 and the lower portion 612 can define a substantially continuous surface 661. In some embodiments, the upper portion 610 has a forward-facing surface 663 that is substantially flush with the front surface 665 of the lower portion 612, or is positioned along the same plane as the front surface 665 of the lower portion 612. The location and size 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.

[0049] like Figure 8 , the upper portion 610 can be rotated approximately 180 degrees about the hinge 618 to engage the rear side of the chin rest 612. This allows a user sitting astride the back section 620 to place their chin on the chin support 612. The chin rest 612 can be spaced apart from the handle 670 to allow the user to rest their arms on the handle 670, which can be padded. The first coupler 680 and the second coupler 682 can be removably attached to each other (e.g., by magnetism, Velcro attachment, etc.) to hold the upper portion 610 in place.
