The present invention relates to a multi-chamber support pillow and, more particularly, to a support pillow with a unique multi-chamber design for use by either side or back sleepers.
There are many types of pillows. There are pillows for infants, for children and for adults. There are pillows that have simple designs, and there are pillows with complex designs. More complicated designs include pillows with multiple internal compartments, such as shown in U.S. Pat. Nos. 6,988,286; 6,401,279; and 5,644,810, each of which is incorporated herein by reference. Other, more complicated designs also include pillows that include some sort of insert, such as shown in U.S. Pat. Nos. 6,151,733; 5,819,347; 4,959,880; and 4,799,275. Still other types of pillow designs, some more intricate than others, are shown in U.S. Pat. Nos. 6,317,908; 5,528,784; 4,606,088; 3,543,313; 2,500,974; 2,942,281 and 705,519. Numerous other pillow designs also exist.
Moreover, there are firm pillows, soft pillows, pillows designed specifically for back sleepers, and pillows designed specifically for side sleepers. Generally, there are pillows designed for every type of preference. However, while pillows of various designs are currently available and/or have been previously proposed, there still remains the need for a pillow that can be utilized more universally, that is, be suitable for use by persons with different types of sleep preferences.
In view of the foregoing, it is an object of the present invention to provide a so-called universal support pillow that is designed to be used by different types of sleepers.
It is a particular object of the present invention to provide a universal support pillow designed for use by both side sleepers and back sleepers.
To achieve the foregoing and other objects, the universal support pillow of the present invention includes a first chamber that defines a first side of the pillow and that has two outer filled compartments and an inner filled compartment (i.e., three baffles), and a second chamber that defines a second side of the pillow. The first chamber is designed to receive a head of a back sleeper, and the second chamber is designed to receive a head of a side sleeper. A closable opening is disposed between the first and second chambers and designed to receive a pillow insert therein (to provide a desired thickness/firmness, as described in the detailed description section below).
As an aspect of the present invention, the two outer compartments/baffles are substantially firmer than the inner compartment/baffle.
As another aspect of the present invention, the inner compartment/baffle is wider than the two outer compartments/baffles.
As a further aspect of the present invention, the second chamber provides a uniform surface on its exterior for the head of the side sleeper.
As an additional aspect of the present invention, each of the compartments of the first chamber and the second chamber are filled with filling materials that may be made of cotton, polyester, feathers, down, Lyocell down or a combination thereof.
As yet a further aspect of the present invention, the pillow insert has a shell with filling material disposed therein, and the pillow insert has a certain amount of thickness and firmness.
As a feature of this aspect, the pillow insert has a filling material that is different than the filling material of the first and second chambers of the pillow.
As yet another aspect of the present invention, two pillow inserts with different thicknesses or firmness levels are provided, and one of the two pillow inserts is received within the pillow's opening.
As a feature of this aspect, the two pillow inserts have different filling materials.
In accordance with a second embodiment of the present invention, the above-summarized universal support pillow is provided, but without the closable opening between the two chambers. In addition, select aspects and features summarized above (and others described below) may be applied to this second embodiment.
Further, and in accordance with the present invention, a method of using a pillow is provided and entails providing a pillow having the above-summarized features, placing by a user who is a back sleeper the second side of the pillow down on a sleeping surface (e.g., a bed), and placing a head of the user on the first side of the pillow, the head of the user being disposed on the inner filled compartment of the first chamber of the pillow, placing by a user who is a side sleeper the first side of the pillow down on a sleeping surface, and placing a head of the user who is a side sleeper on the second side of the pillow.
As an aspect of this method embodiment, the method includes inserting, by the user, within the closeable opening a pillow insert that has a shell and a filling material disposed within the shell.
As a feature of this aspect, the method includes selecting by the user one of two different pillow inserts, and then inserting within the closeable opening the selected pillow insert. The two different pillow inserts differ by the amount of their thickness and/or firmness.
Various other objects, advantages and features of the present invention will become readily apparent to those of ordinary skill in the art, and the novel features will be particularly pointed out in the appended claims.
The following detailed description, given by way of example and not intended to limit the present invention solely thereto, will best be appreciated in conjunction with the accompanying drawings, wherein like reference numerals denote like elements and parts, in which:
As is well known, back sleepers and side sleepers require pillows of different designs to properly support the user's neck and head while sleeping. Back sleepers typically generally require pillows that suitably support the sleeper's neck while cradling the head. These types of pillows, however, are often ill-suited for side sleepers who require an even sleeping surface for proper neck alignment.
The universal support pillow of the present invention, as described in detail below, provides a unique pillow well-suited for both back and side sleepers. In accordance with the present invention, the universal support pillow includes multiple, separate chambers with different characteristics designed for use by different types of sleepers. More particularly, and referring to
Bottom chamber 30 and each of the baffles 20A, 20B and 20C is filled with suitable filling material 14. Filling material 14 may be cotton, polyester, feathers, down, a combination of feathers and down, or other known filling material. Preferably, the filling material 14 is the filling material described in U.S. Pat. No. 7,074,242, generally referred to as Lyocell Down. U.S. Pat. No. 7,074,242 is owned by the assignee of the present invention and is incorporated herein by reference.
In accordance with the present invention, baffles 20A, 20B and 20C, which collectively form the pillow's top chamber 20, have characteristics particularly well-suited for back sleepers. Specifically, the outer baffles 20A and 20C are filled with suitable filling material 14 to be relatively firm as compared to the firmness of center baffle 20B, thus providing a multi-baffle design that properly supports a user's neck (via one of the firmer baffles 20A or 20C), while, at the same time, providing a softer support (i.e., baffle 20B) that gently cradles the head during sleeping or resting. This multi-baffle design of the present invention provides for improved neck alignment which, in turn, provides for reduced snoring. Moreover, to further accommodate the user's head, the width of the center baffle 20B is slightly greater than the width of the outer baffles 20A and 20C. In the exemplary design shown in
Also in accordance with the present invention, bottom chamber 30 is a single compartment filled with filling material 14 to provide a uniform sleeping surface that is particularly well-suited for side sleepers. Given both the multi-baffle top chamber 20 and the single, uniform bottom chamber 30, the universal support pillow of the present invention is reversible and designed for use by either a side sleeper or a back sleeper.
The universal support pillow further includes opening 40, as mentioned above, disposed between the pillow's top chamber 20 and the pillow's bottom chamber 30. In accordance with the present invention, one of a multiple number of types of “pillow inserts” 42 (shown in
As a particularly useful feature of the present invention, the end user may be provided with multiple types of pillow inserts and, depending on the user's desired pillow characteristics, the user selects one of those pillow inserts and inserts the selected pillow insert within mid-chamber 40. As an example, the user can select a relatively firm pillow insert for use one night, and select a relatively soft pillow insert for use another night. As a further example, the user can select a relatively thick pillow insert for use one night, and select a relatively thin pillow insert for use a different night. Thus, pillow inserts may have different firmness levels and/or different thicknesses and/or other different characteristics. If desired, the pillow may be utilized by different people at different times, wherein a pillow insert with one set of characteristics is selected for use by one person, and a different pillow insert with different characteristics is selected for use by a different person.
In accordance with the present invention, and as discussed above, the universal support pillow of the present invention advantageously is well-suited for both side and back sleepers. A back sleeper places the pillow with the bottom chamber down and places one's head on the multi-baffled top chamber. The multi-baffle top chamber design provides proper support of a user's neck, gently cradles the user's head for improved neck alignment, and provides for reduced snoring, among other benefits. A side sleeper places the pillow with the top chamber down and places one's head on the single compartment bottom chamber that provides for a uniform sleeping surface best-suited for side sleepers.
The universal support pillow of the present invention also, in certain embodiments, enables a user to select any one of a number of inserts to be placed within the insert opening of the pillow in order to provide characteristics most desired by the individual user. That user or other users of the universal support pillow of the present invention may, as desired, change the insert in order to modify the pillow's characteristics, as well as use the different sides of the pillow, as desired.
The present invention has been described in the context of a number of embodiments, and a number of variations thereof. It is to be understood, however, that other expedients known to those skilled in the art or disclosed herein may be employed without departing from the spirit of the invention. Therefore, it is intended that the appended claims be interpreted as including the embodiments described herein, the alternatives mentioned above, and all equivalents thereto.
This application claims priority to U.S. provisional patent application No. 61/043,852, filed Apr. 10, 2008, the disclosure of which is incorporated herein by reference.
