Stools, chairs, and methods using the same
An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.
1. A support assembly comprising:
a base assembly configured to rest on a support surface; and
a chest support assembly coupled to the base assembly and including:
a chest support having a front side and a backside, wherein the backside of the chest support is configured to support a chest of a user facing the chest support, wherein the chest support is moveable from an inclined position to an upright position while the base assembly is supported by the support surface, and
at least one armrest rotatable about an axis of rotation between an upright stowed position and a deployed position, wherein the at least one armrest, in the deployed position, is located on the front side of the chest support to support the user's forearm while the user's chest contacts the backside of the chest support, wherein a support surface of the at least one armrest, in the upright stowed position, is flush with the backside of the chest support.
2. The support assembly of claim 1 , further comprising:
an elongated assembly connecting the base assembly to the chest support, and
at least one pivot that couples the chest support assembly to the base assembly.
3. The support assembly of claim 1 , wherein the at least one armrest is movable between an unextended configuration and an extended configuration.
4. The support assembly of claim 1 , wherein the chest support assembly has an unexpanded configuration and an expanded configuration, wherein the chest support assembly includes an upper chest support movable away from the chest support such that the upper chest support is spaced apart from the chest support in the expanded configuration.
5. The support assembly of claim 1 , further comprising an armrest positioner assembly defining a plurality of angular positions of the at least one armrest, and wherein the armrest positioner assembly has a locked state for holding the armrest stationary relative to the chest support and an unlocked state for allowing movement of the armrest relative to the chest support and between the angular positions.
6. The support assembly of claim 1 , wherein the chest support and the at least one armrest are dimensioned to overlay the chest of the user while the user leans forward against the chest support.
7. The support assembly of claim 1 , wherein the at least one armrest is at a vertical orientation when in the stowed position, and wherein the at least one armrest is at a horizontal orientation when in the deployed position.
8. The support assembly of claim 1 , wherein the at least one armrest is rotatable along an arc in a range from about 80 degrees to about 90 degrees.
9. The support assembly of claim 1 , wherein the chest support defines an armrest-receiving opening that receives the armrest when the armrest moves from the deployed position to the stowed position.
10. The support assembly of claim 1 , wherein the chest support assembly further includes a pivoting mechanism that in an unlocked state allows the chest support to rotate relative to the base assembly and in a locked state prevents rotation of the chest support relative to the base assembly.
11. The support assembly of claim 1 , further comprising a vertical lift mechanism having a locked state and an unlocked state, wherein the vertical lift mechanism in the unlocked state allows vertical movement of the chest support relative to the base assembly, and wherein the vertical lift mechanism in the locked state prevents vertical movement of the chest support relative to the base assembly.
12. The support assembly of claim 1 , wherein the chest support has a concave upper region positioned to be underneath the user's chin when the user's chest contacts and is centered with the backside of the chest support.
13. A support assembly, comprising:
a chest support configured to contact a user's chest; and
an armrest rotatably coupled to the chest support, an end of the armrest moves away from the chest support and the user's chest when the armrest rotates from a raised vertical position for supporting the user's chest to a lowered horizontal position for supporting the user's arm while the support assembly is supported by a horizontal support surface, wherein the armrest in an unexpanded state is configured to fit within an armrest-receiving portion of the chest support and in an expanded configuration is longer than the armrest-receiving portion.
14. The support assembly of claim 13 , wherein the chest support has a concave upper portion configured to be positioned underneath the user's chin when the user's chest is centered relative to and contacts the chest support.
15. The support assembly of claim 13 , further comprising an extension mechanism movable between an undeployed state in which the armrest is positioned within an armrest-receiving portion of the chest support and a deployed state in which the armrest is positioned outside of the armrest-receiving portion.
16. The support assembly of claim 13 , wherein the armrest is movable between a plurality of preset angular positions relative to the chest support.
17. The support assembly of claim 13 , further comprising a vertical adjustment mechanism operable to vertically move the chest support relative the support surface.
18. The support assembly of claim 13 , wherein the chest support is rotatable between a vertical orientation and a non-vertical orientation.
19. A support assembly, comprising:
a chest support positioned to contact a user's chest; and
an armrest with a support surface and movable relative to the chest support to move the support surface away from the user's upper body as the armrest moves from a first position toward a second position,
wherein when the armrest is in the first position, the support surface of the armrest is positioned to be substantially flat along the user's upper body and a chest support surface of the chest support and the support surface cooperate to define a substantially gapless contact region positioned to support the user's upper body,
wherein when the armrest is in the second position, the support surface is positioned to support the user's arm.
20. The support assembly of claim 19 , further comprising a pivoting mechanism having an unlocked state for allowing rotation of the chest support and a locked state for preventing rotation of the chest support.
21. A support assembly, comprising:
a base; and
a chest support assembly coupled to the base and including a chest support and armrests, wherein each armrest is movable between a raised position for being substantially flush with a chest support surface and a lowered position for supporting a user's arm located on a front side of the chest support, and wherein the chest support surface and the armrests in the raised position are configured to support the user's torso positioned against a backside of the chest support.
22. The support assembly of claim 21 , wherein the base includes a plurality of wheels.
