## Background
BACKGROUND
1. Field of the Invention
The present invention relates to pillows, more specifically to pillows with an internal pivotable frame.
2. Description of the Related Art
Lack of relaxation and sleep can be detrimental to an individual's health. Sleep deprivation can lead to decreased performance and alertness, memory and cognitive impairment, stress, automobile injury, or occupational injury. Sleep deprivation research is vast and ongoing but common causes include sleep disorders and environmental factors such as noise and light. Achieving deep sleep with a snoring partner or at noisy environment such as airport and hospital can be difficult. Individuals may have trouble finding a private place in order to block out surrounding sound and light, and may struggle to find sleep comfort while seated in a near upright position.
To alleviate sleeping problems while traveling, some consumers may use ear plugs or eye masks to block out disruptive sounds or lights, as well as portable, supportive neck pillows for upper-body comfort. Some neck pillows are preformed C-shaped cushions that wrap around the sides and back of a user's neck, to the extent that preforming allows the conformity to the neck, allowing the user to support their head in an upright fashion while seated upright. This may prevent neck cricks and pains due to slouching of the user's head while sleeping in an upright position. However, neck pillows do not offer adequate support or cushioning for the back portions of user's head, resulting in discomfort and the head resting backwards onto the neck pillow alone with no support from the seat. Compounding the issues related to current neck pillows and traveling environments is the presence of ambient noise and light. These environments can prevent some individuals from achieving deep sleep. Thus a need exists for a pillow which facilitates deep sleep while suboptimal environmental conditions.

The present invention is directed to a pillow 10 with an internal pivotable frame 20 whereby its user can selectively manipulate the pillow to cover a partial perimeter around its head 08. In exemplary use, the pillow 10 is manipulated from a generally open or state to a generally concave, enclosed state with the curvature conforming to a partial perimeter of the head 08 and covering the ears 04 prior to sleep in a bed or seat. FIG. 1 illustrates an embodiment of a pillow 10 with an internal pivotable frame 20 in an open relatively planar state. Illustrated are the accoutrements of a pillow and an internal pivotal frame 20.
In exemplary configuration, the pillow 10 is engaged to a user's head 08 and covers the ears 04 of the user in its enclosed state. Referring to FIGS. 4a and 4b, a representative user head 08 is shown. The head 08 has an approximate height of y′ from about the top of the head 08 to the neck. The head 08 presents a partial perimeter circumference of x′ spanning from about the first ear 04 to the back of the head 08 to the second ear 04. It should be understood that the height y′ and ear 04 to ear 04 partial perimeter can vary.
The interior of the pillow 10 includes a pivotable frame 20. FIGS. 3a and 3c show top views of pivotable frames 20 in an open state, while FIGS. 3b and 3d show top views of the corresponding pivotable frames 20 in their enclosed state, where it is curved about a point 28 to form a partial enclosure.
In one configuration, the pivotable frame 20 includes a unitary semi-rigid leg 26. The leg 26 is flexible substantially along its entire length. In exemplary configuration, the length x of the pivotable frame 20 is about the same as the target partial perimeter x′, with the length of the pillow 10 following the contour of the head 08 and the ends of the pivotable frame 20 causing pillow 10 contact with each of the ears 04. The leg 26 is composed of semi-rigid, selectively, flexible material such as metals, plastics, composites, or other suitable material.
In an alternate embodiment, the pivotable frame 20 includes a plurality of interconnected leg 26 and joint 22 sections. In exemplary configuration, the length x of the pivotable frame 20 is about the same as the target partial perimeter x′, with the length of the pillow 10 following the contour of the head 08 and the ends of the pivotable frame 20 causing pillow 10 contact with each of the ears 04. It is within the scope of this invention to vary the length of one or more legs 26 such that its length is at or less than a configured proportion of the total length of the interconnected leg 26 and joint 22 sections. For example, a leg 26 and joint 22 section length may be configured at less than 10% of the total length of the interconnected leg 26 and joint 22 sections, altering the degree of conformity to the head 08.
