DETAILED DESCRIPTION

Reference will now be made to a preferred embodiment, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that these embodiments are not intended to limit the scope of the invention. On the contrary, the invention is intended to cover alternatives, modifications, and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. As such, the description of the embodiments that follow are for purposes of illustration and not limitation.
FIG. 1 is a perspective view of a tub or spa structure 10 with a spa shell pillow 12, according to an embodiment of the present invention. The spa structure 10 may include a mounting surface 14 for coupling the spa shell pillow 12 onto the spa structure 10. In one embodiment, the mounting surface 14 may be recessed with respect to the surrounding region 16 of the spa structure 10. For example, the mounting surface 14 may be contoured inward so as to create a concavity for receiving a user's head.
A detailed structure of the spa shell pillow 12 is further illustrated in FIG. 2. The spa shell pillow 12 may be made from an elongated dense foam material 20 with a support frame 18. The spa shell pillow 12 may include a first engaging member 22 and a second engaging member 24 for receiving and engaging a first fastener 26 and a second fastener 28, respectively. The first 26 and the second fastener 28 being coupled to the mounting surface 14 using, for example, screws 30 and 32, to cooperatively mount the spa shell pillow 12 to the spa structure 10. The first 26 and second 28 fasteners may be cantilevered horseshoe fasteners that mate with the first 22 and second 24 engaging members.
The spa shell pillow 12 is preferably sized and shaped to receive and position the user's head 34. In one embodiment, the spa shell pillow 12 may be configured to arch in a bow-like fashion, leaving an air gap 36 in the middle between a first pillow base 35 and a second pillow base 37. When supporting the user's head 34′ the arched spa shell pillow 12 deflects, from a first position 38 to a second position 40, providing a perception of softness as it gives way in the middle to the shape of the user's head 34.
In one embodiment, the spa shell pillow 12 has an arched elongated body with a front surface and a back surface, the front surface receiving a user's head 34, the back surface having at least two pillow bases 35, 37 coupled to the mounting surface 14, the arched elongated body forming an air gap 36 between the at least two pillow bases 35, 37 to provide space for deflection of the arched elongated body when receiving the user's head.
As can be envisioned by a person skilled in the art, the spa shell pillow 12 may have various configurations included within the spirit and scope of the invention. For example, the spa shell pillow 12 may include at least one pillow base 35 with at least one engaging member 22 for receiving and engaging at least one fastener 26.
The spa shell pillow 12 may be adapted to injection molding or exothermic foam molding processes. The spa shell pillow 12 may be fabricated from various materials known in the art, including cross-linked polyethylene material, Ethyl Vinyl Acetate (EVA) foam, or the like. Preferably, the material used exhibits low-temperature properties, hydrolysis resistance, and/or fungus resistance, and is suitable for injection molding, blow molding, or extrusion.
While it is advantageous to integrally mold the spa shell pillow 12 as a unitary molded article to provide for easy manufacture and a pleasant soft feel, structures according to the invention could be fabricated of several individually molded or otherwise separately fabricated parts attached together by various conventional means. Thus, for example, support frame 18 may be fabricated in one step, for example, by molding or other processes, and elongated dense foam material 20 formed in a separate step and attached to the support frame 18 by bonding or other processes.
FIG. 3 is a perspective view of spa structure 10 for cooperating with the spa shell pillow 12 of FIG. 1. The spa structure 10 may include mounting surface 14 with first fastener 26 and second fastener 28. The first 26 and the second fastener 28 being coupled to the mounting surface 14 using, for example, screws 30 and 32. As illustrated in FIG. 2, the fasteners 26 and 28 may be positioned behind the spa shell pillow, as desired, to provide for appropriate concealment. FIG. 4 is a perspective view of fastener 26 coupled to the mounting surface 14, using one or more screws 32. As can be envisioned by a person skilled in the art, various mounting means may be used to couple the spa shell pillow 12 to the mounting surface 14. For example, the fastener 26 may be coupled to the mounting surface 14 by gluing or bonding. Another example may include gluing, bonding or attaching the spa shell pillow 12 directly to the mounting surface 14 without using fasteners.
The spa shell pillow 12 may have first engaging member 22 and second engaging member 24 formed from a cavity in first pillow base 35 and in second pillow base 37, respectively. In one embodiment, the first engaging member 22 and second engaging member 24 include a first lip and a second lip. The first lip and the second lip engage cantilevered arm 50 of fastener 26, 28, shown in FIG. 4.
In one embodiment, the spa shell pillow 12 may have a cutout on the back side. The cutout may decrease the thickness of the spa shell pillow 12 to allow further deflection of the spa shell pillow 12 when supporting the user's head 34. The cutout may also allow insertion of a light source (not shown) to provide backlight effects to the spa shell pillow 12.
While the apparatus and method have been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the disclosure need not be limited to the disclosed embodiments. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structures. The present disclosure includes any and all embodiments of the following claims.
