Flexing support in a spa
View Patent ↗Systems and techniques to provide a flexing support in a spa, such as a flexing spa headrest. In general, in one implementation, a system includes a surface defining a multi-level recess including a primary recess and secondary mounting recesses, and a pillow including a flexible concave pad and mounts that couple the flexible concave pad with the surface, the secondary mounting recesses receiving the mounts such that the flexible concave pad is suspended above the primary recess, a curved edge of the flexible concave pad contacts the surface, and the flexible concave pad mechanically flexes concavely between the mounts and about the curved edge when force is applied.
1. A system comprising:
a surface defining a multi-level recess including a primary recess and secondary mounting recesses; and
a pillow comprising a flexible concave pad and mounts that couple the flexible concave pad with the surface, the secondary mounting recesses receiving the mounts such that the flexible concave pad is suspended above the primary recess, a curved edge of the flexible concave pad contacts the surface, and the flexible concave pad mechanically flexes concavely between the mounts and about the curved edge when force is applied at or near the center line of the pillow.
2. The system of claim 1 , wherein the surface defines the primary recess having a curve that accommodates a large variety of head sizes and shapes.
3. The system of claim 1 , wherein the surface defines the primary recess having an overall angle that promotes correct posture and head positioning.
4. The system of claim 1 , wherein the flexible concave pad has a thin material cross section with a thickness of between 0.25 inches and 0.7 inches.
5. The system of claim 4 , wherein the thickness is between 0.4 inches and 0.6 inches.
6. The system of claim 4 , wherein the flexible concave pad comprises Urethane and Silicone.
7. The system of claim 4 , wherein the flexible concave pad comprises Ethylene Vinyl Acetate.
8. The system of claim 1 , wherein the surface defines the secondary mounting recesses as stepped recesses.
9. The system of claim 1 , wherein the mounts comprise flexible pins that couple with the flexible concave pad in a cantilevered fashion, each flexible pin comprising a flange and a boss, wherein the flange has a beveled side facing one of the secondary mounting recesses.
10. The system of claim 9 , wherein each flexible pin further comprises a surface defining a thread on a proximate end of the pin and a surface defining a slot on a distal end of the pin.
11. The system of claim 1 , further comprising a free-standing spa, wherein the surface comprises at least a portion of a spa shell of the free-standing spa.
12. The system of claim 1 , further comprising a spa and a housing that couples with a spa wall of the spa, wherein the surface comprises at least a portion of the housing.
13. The system of claim 12 , wherein the housing includes jets and pipes that feed the jets.
14. A spa comprising the system of claim 1 and further comprising a spa wall.
15. The spa of claim 14 , wherein the surface defines the primary recess having dimensions that accommodate a large variety of head sizes and shapes and that promote correct posture and head positioning.
16. The spa of claim 15 , wherein the mounts comprise flexible pins, including means for screwing the flexible pins into the flexible pad, and the flexible pad has a thin material cross section with a thickness of between 0.25 inches and 0.7 inches.
17. The spa of claim 16 , further comprising a housing that couples with the spa wall.
