FIELD OF THE INVENTIONThe present invention relates to housekeeping accessories, and more specifically provides a pillowcase changing tool and a method of use.
BACKGROUND OF THE INVENTIONInserting pillows into pillowcases and removing pillowcases from pillows can be a time-consuming and frustrating event occurring in all types of institutions, such as hospitals and hotels, as well as individual residences. There have been attempts in the past to minimize this problem; however, previous devices tend to be bulky, awkward in use, and/or contain other limitations. An improved pillowcase changing tool is desired. Therefore, there is further need in this area, and more specifically a need for a device that can reduce resistance between a pillow and a pillowcase that makes changing pillowcases a difficult task. The present invention is directed to meeting those needs, among others.
SUMMARY OF THE INVENTIONThe present invention deals primarily with a pillowcase changing tool, generally including, in one embodiment, a pair of parallel X braces or expanders connected to each other by a pair of parallel base members. Each expander includes two slats connected at a middle pivot point. The expanders are positioned generally parallel to each other creating a slot for receipt of a pillow. The first base member extends between first proximal points of the expanders, and the second base member extends between second proximal points of the expanders. The separation distance of the base members controls the expansion of the expanders. Optionally, the spacing between the expanders is adjustable along the lengths of the base members.
Objects of certain preferred embodiments of the present invention will become apparent from the description, figures and claims herein.
DESCRIPTION OF THE FIGURES
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations, modifications, and further applications of the principles of the invention being contemplated as would normally occur to one skilled in the art to which the invention relates.
In accordance with an embodiment of the present invention, a pillowcase changing apparatus is provided. The apparatus includes a pair of parallel X brace expanders and a pair of parallel base members. Each of the expanders includes two slats connected at a middle pivot point. Additionally, each expander includes a first end and a second end. The first ends include first proximal points and second proximal points. The X brace expanders are positioned generally parallel to each other creating a slot for receipt of a pillow. The first base member extends between the first proximal point of each of the X brace expanders. The second base member extends between the second proximal point of each of the X brace expanders. In accordance with this embodiment, selective separation of said base members controls expansion of the expanders. In another embodiment, the spacing of the expanders is adjustable along the length of the base members.
To change a pillowcase using the pillowcase changing device, the X braces of the device are inserted between a pillowcase and a pillow maintained in the pillowcase with the second X brace on the opposite side of the pillow from the first X brace. The X braces are inserted to a position where top ends of the first and second X braces are positioned near inner corners of the pillowcase and the base members of the device are positioned near an opening of the pillowcase, with the pillowcase at least partially covering each of the X braces. The base members may be pre-spaced or selectively spaced after insertion so that the expanders have a width approximately that of the pillow. Thereafter, the pillowcase is removed from the pillow and the device, with the pillow being maintained in the device.
To put a pillowcase on a pillow using the device, a pillow is inserted and held between the X braces of the device. A pillowcase is placed over the pillow and the X braces, resulting in the device being positioned between the pillowcase and the pillow. Thereafter, the X braces are removed from between the pillowcase and the pillow.
Referring now to
In certain embodiments, slats 16 and 18, and slats 20 and 22, are pivotally connected with pivot bolts 24a and 26a, respectively, extending through holes in the slats. Alternatively, other methods of connecting the slats together can be used as would generally occur to one skilled in the art. Further, it should be appreciated that the X braces can be single, continuous members.
As shown in
The X braces are expandable and contractible relative to the midpoints along an x-axis to adjust for varying widths of pillows. Optionally, the spacing of the X braces is also adjustable along the lengths of the base members, along a y-axis, to adjust for varying thicknesses of pillows. In certain embodiments, the slats are flat bars, with a generally rectangular cross-section. In a preferred embodiment, edges 16a, 16b, 18a, 18b, 20a, 20b, 22a and 22b of slats 16, 18, 20 and 22 are rounded. The rounded edges of the X braces prevent material from getting caught on the edges during operation of the device. It should be appreciated that the slats can be generally cylindrically shaped with a circular cross-section, or shaped differently as would generally occur to one skilled in the art. In certain example embodiments, the slats measure 30 inches in length; however, it should be appreciated that the slats could be shorter or longer as would occur to one skilled in the art. Additionally, in another embodiment, the slats can telescopically extend to accommodate longer pillows.
In the illustrated embodiment, X braces 12 and 14, along with base members 50 and 52, create a slot 66 for receipt of a pillow. In certain embodiments, the slats are made from a flexible material to accommodate thicker pillows. Additionally, the endpoints can include rounded tips to aid in placement and removal of the pillowcase over the device. Alternatively, the endpoints can include pointed tips to aid in placement and removal of a pillowcase over the device.
Optionally, the slats can each be enhanced to include a gripping interior surface 60 to better maintain contact with a pillow positioned within device 10. Examples of such enhancement include treating the surfaces, texturing the surfaces, roughening the surfaces, and/or adding textured materials to the surfaces. In certain embodiments, the slats can each also be enhanced to include a smooth, slick exterior surface 62 to aid in placement and removal of a pillowcase over device 10. Examples of such enhancement include treating the surfaces and/or adding materials to the surfaces.
In the illustrated embodiment, base members 50 and 52 are elongate bars with a rectangular cross-section. The illustrated base members provide stability for device 10 when resting on the base members. However, it should be appreciated that the base members can be configured differently as would generally occur to one skilled in the art. As an example, the base members can have circular cross-sections. In the illustrated embodiment, base members 50 and 52 extend along a y-axis, the y-axis being substantially perpendicular to the x-axis, as shown in
In the embodiment illustrated in
Optionally, the base members can have two or more holes 70 to allow selective adjustment of the X braces along the base members corresponding to varying thicknesses of pillows. Providing numerous holes in the base members allows for adjustability of the X braces along the y-axis. Screws inserted through the base members into the support members secure the X braces to the base members. It should be appreciated that other hardware can be used to connect the X braces to the base members, such as quick release pins, clevis pins, hitch pins, and various types of other pieces as would generally occur to one skilled in the art.
In certain embodiments, support members 64 are connected to endpoints 28, 30, 36 and 38 of slats 16, 18, 20 and 22 with a pivot bolt 72 secured by a pin 73. Pivot bolt 72 allows for pivotal connection between the support members and the slats. Other pivot connection mechanisms can be used to connect the slats to the support or base members as would generally occur to one skilled in the art.
Regarding the connection of the X braces to the base members, in another embodiment, the endpoints, such as endpoints 28, 30, 36 and 38, are received in holes in the base members in a manner as to permit pivoting of the slats relative to the base members. In alternative embodiments, there are holes in the slats near the endpoints, with the base members received through the holes, as illustrated in
The primary components of devices 10 and 100, in certain example embodiments, are made of wood-based materials. However, it should be appreciated that the components of devices 10 and 100 can be made from various other alternative materials, such as plastic or metal, or other materials as would generally occur to one skilled in the art.
Referring generally to
To place a pillowcase on a pillow, device 10 can be stood upright, as shown in
Referring again to
Various alternative embodiments of the configuration and use of the device are contemplated. In one alternative embodiment, a handle or central crossbar is used to connect the base members. The handle can be used to move the base members closer together or farther apart and optionally to secure them at desired separations. In another embodiment, spring means can be used to bias the X braces either towards each other or away from each other to aid in the use of the device.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
