Fastenerless ergonomic knee rest unitary construction chair
View Patent ↗A knee-rest economic chair is provided. The knee-rest economic chair is formed from a unitary construction, fastener-less assembly, wherein the chair provides an elevated posterior condition as an elevated knee rest for seated users. The chair may be assembled from a plurality of components all of which are formed from a planar blank of one material. The components have tabs and slots for joined adjacent components that results in a seat component spaced apart and elevated above a knee support component, positioned relative to each other in an elevated posterior position, wherein gravity secures the resulting tab-slot and slot-slot joints, making separate fasteners unnecessary.
1. A system for providing the components for assembling a knee-rest chair in a planar arrangement, comprising:
a planar blank of one material defining a plurality of components comprising:
two U-shaped upright components having coextensive distal portions and coextensive proximal portions, wherein the proximal portions extend farther from a base portion of each U-shaped upright component;
two intermediate components for spacing the two U-shaped upright components apart of the assembled knee-rest chair;
a seat component adapted to operatively engage the proximal portions of the assembled knee-rest chair;
a knee support component adapted to operatively engage the distal portions of the assembled knee-rest chair; and
a bottom component disposed between the two intermediate components and interconnecting said base portions of the assembled knee-rest chair.
2. The system of claim 1 , further comprising a plurality of tabs and/or slots on each of the plurality of components for operatively engaging each other for providing the assembled knee-rest chair without the use of separate fasteners.
3. The system of claim 1 , further comprising a plurality of wheels defined by the planar blank, wherein the two upright components provide two wheel portions for rotatably associating with the plurality of wheels of the assembled knee-rest chair.
4. The system of claim 1 , wherein the planar blank is made of only wood.
5. The system of claim 1 , wherein the planar blank is made of only plywood.
6. The system of claim 1 , wherein the planar blank is 48 by 48 inches square.
7. A system for providing the components for assembling a knee-rest chair in a planar arrangement, comprising:
a planar blank of one material defining a plurality of components comprising:
two U-shaped upright components having coextensive distal portions and coextensive proximal portions, wherein the proximal portions extend farther from a base portion of each U-shaped upright component;
two intermediate components for spacing the two U-shaped upright components apart of the assembled knee-rest chair;
a seat component adapted to operatively engage the proximal portions of the assembled knee-rest chair; and
a knee support component adapted to operatively engage the distal portions of the assembled knee-rest chair;
a plurality of tabs and/or slots on each of the plurality of components for operatively engaging each other for providing the assembled knee-rest chair without the use of separate fasteners;
a bottom component disposed between the two intermediate components and interconnecting said base portions of the assembled knee-rest chair; and
a plurality of wheels defined by the planar blank, wherein the two upright components provide two wheel portions for rotatably associating with the plurality of wheels of the assembled knee-rest chair.
8. The system of claim 7 , wherein the planar blank is made of only wood.
9. The system of claim 7 , wherein the planar blank is made of only plywood.
10. The system of claim 7 , wherein the planar blank is 48 by 48 inches square.
11. A system for providing the components for assembling a knee-rest chair in a planar arrangement, comprising:
a planar blank of one material defining a plurality of components comprising:
two U-shaped upright components having coextensive distal portions and coextensive proximal portions, wherein the proximal portions extend farther from a base portion of each U-shaped upright component;
two intermediate components for spacing the two U-shaped upright components apart of the assembled knee-rest chair;
a seat component adapted to operatively engage the proximal portions of the assembled knee-rest chair;
a knee support component adapted to operatively engage the distal portions of the assembled knee-rest chair; and
a plurality of wheels defined by the planar blank, wherein the two upright components provide two wheel portions for rotatably associating with the plurality of wheels of the assembled knee-rest chair.
12. The system of claim 11 , further comprising a plurality of tabs and/or slots on each of the plurality of components for operatively engaging each other for providing the assembled knee-rest chair without the use of separate fasteners.
13. The system of claim 11 , wherein the planar blank is made of only wood.
14. The system of claim 11 , wherein the planar blank is made of only plywood.
15. The system of claim 11 , wherein the planar blank is 48 by 48 inches square.
