BRIEF SUMMARY OF THE INVENTION
Disclosed is a system and method for simply and efficiently improving on personal privacy, particularly in a portable or temporary format. The following summary of the invention is provided to facilitate an understanding of some of the technical features related to portable personal privacy screen, and is not intended to be a full description of the present invention. A full appreciation of the various aspects of the invention can be gained by taking the entire specification, claims, drawings, and abstract as a whole. The present invention is applicable to other screens for other purposes and in some instances to less portable implementations.
An embodiment of the present invention may include a flexible oblong perimeter frame closed with a covering configured to be bowed into an arch, and an arch-retaining system coupled to ends of the frame maintaining the frame.
An embodiment of the present invention may provide that the arch-retaining system include a pair of attachment structures disposed at ends of the frame and a strap having a pair of ends, each strap end including an engagement system complementary to the attachment structures to maintain an arched flexible frame in the arched configuration. Some implementations of this embodiment may allow a user to use the portable personal privacy screen in a “stand-alone” environment, such as in front of a fireplace, camp fire or other space where the user would like to establish a personal zone.
An embodiment of the present invention may provide that the arch-retaining include retainers that cooperate with the ends of an arched flexible frame and some other structure, such as mattresses of a bed. In some cases, a pair of these retainers may partially extend under a mattress while revealing a clip or holder structure beyond lateral edges of the mattress. Each clip or holder structure cooperatively engages an end of the arched flexible retainer and maintaining it in the arched configuration, like a canopy passing overhead a portion of the top surface of the mattress. The retainers may be retrofit retainers able to be added for virtually any sleeping system, or integrated into the sleeping system. Some implementations of this embodiment may allow a user to simply and easily remove and add the privacy screen (e.g., to make the bed and then re-install or other reason for removal and re-addition).
A portable screen, including an elongate flexible closed loop perimeter frame including a planar mode and a three dimensional (3D) mode with the frame configured for repeatable transitions between the modes, the frame defining a first end, a second end spaced apart from the first end by a first distance, and a body portion disposed between the ends wherein the ends define a plane for the modes, wherein the ends and the body portion are disposed within the plane in the planar mode and separated by the first distance, and wherein the ends are disposed within the plane while the body portion is disposed out of the plane in the 3D mode with the ends spaced apart a second distance in the 3D mode wherein the second distance is less than the first distance and wherein the frame includes a biasing arrangement to apply a biasing force to automatically bias a transition from the 3D mode to the planar mode whenever the frame is transitioned to the 3D mode from the planar mode; a flexible material covering the frame; and a retainer system selectively engageable with the ends to maintain the frame in the 3D mode against the biasing force as long as the ends are engaged; wherein the frame is configured to automatically transition to the planar mode from the 3D mode whenever the retainer system disengages from at least one of the ends.
A method for producing a privacy screen, including a) transitioning an elongate flexible closed loop perimeter frame from a planar mode to a three dimensional mode, the frame including the planar mode and the three dimensional (3D) mode with the frame configured for repeatable transitions between the modes, the frame defining a first end, a second end spaced apart from the first end by a first distance, and a body portion disposed between the ends wherein the ends define a plane for the modes, wherein the ends and the body portion are disposed within the plane in the planar mode and separated by the first distance, and wherein the ends are disposed within the plane while the body portion is disposed out of the plane in the 3D mode with the ends spaced apart a second distance in the 3D mode wherein the second distance is less than the first distance and wherein the frame includes a biasing arrangement to apply a biasing force to automatically bias a transition from the 3D mode to the planar mode whenever the frame is transitioned to the 3D mode from the planar mode and including a flexible material covering the frame; and b) securing the frame in the 3D mode using a retainer system selectively engageable with the ends to maintain the frame in the 3D mode against the biasing force as long as the ends are engaged; wherein the frame is configured to automatically transition to the planar mode from the 3D mode whenever the retainer system disengages from at least one of the ends.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention provide a system and method for simply and efficiently improving on personal privacy, particularly in a portable or temporary format. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements.
Various modifications to the preferred embodiment and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein.
DEFINITIONS
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this general inventive concept belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The following definitions apply to some of the aspects described with respect to some embodiments of the invention. These definitions may likewise be expanded upon herein.
As used herein, the term “or” includes “and/or” and the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
As used herein, the singular terms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an object can include multiple objects unless the context clearly dictates otherwise.
Also, as used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise. It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.
As used herein, the term “set” refers to a collection of one or more objects. Thus, for example, a set of objects can include a single object or multiple objects. Objects of a set also can be referred to as members of the set. Objects of a set can be the same or different. In some instances, objects of a set can share one or more common properties.
As used herein, the term “adjacent” refers to being near or adjoining. Adjacent objects can be spaced apart from one another or can be in actual or direct contact with one another. In some instances, adjacent objects can be coupled to one another or can be formed integrally with one another.
As used herein, the terms “connect,” “connected,” and “connecting” refer to a direct attachment or link. Connected objects have no or no substantial intermediary object or set of objects, as the context indicates.
As used herein, the terms “couple,” “coupled,” and “coupling” refer to an operational connection or linking. Coupled objects can be directly connected to one another or can be indirectly connected to one another, such as via an intermediary set of objects.
The use of the term “about” applies to all numeric values, whether or not explicitly indicated. This term generally refers to a range of numbers that one of ordinary skill in the art would consider as a reasonable amount of deviation to the recited numeric values (i.e., having the equivalent function or result). For example, this term can be construed as including a deviation of ±10 percent of the given numeric value provided such a deviation does not alter the end function or result of the value. Therefore, a value of about 1% can be construed to be a range from 0.9% to 1.1%.
As used herein, the terms “substantially” and “substantial” refer to a considerable degree or extent. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation, such as accounting for typical tolerance levels or variability of the embodiments described herein.
As used herein, the terms “optional” and “optionally” mean that the subsequently described event or circumstance may or may not occur and that the description includes instances where the event or circumstance occurs and instances in which it does not.
As used herein, the term “oblong” means a perimeter that is longer than it is wide. A preferred oblong perimeter is sometimes referred to as a “racetrack” defined by a pair of equal diameter semicircular discs joined to ends of a rectangle having a width equal to the diameter. Other oblong shapes may include a rectangle, oval, elliptical, or other perimeter shape. Preferably, but not required, is that the oblong have at least one axis of symmetry (e.g., a longitudinal axis extending along its length), and more preferred is to have two axes of symmetry (the longitudinal axis and a lateral axis perpendicular to the longitudinal axis extending across its width).
FIG. 1 illustrates an oblong flexible panel 100 in an un-arched or flat mode, FIG. 2 illustrates components of an embodiment of a portable personal privacy screen system 200 with oblong flexible panel 100 in an intermediate mode, which may be transitioning to or from the un-arched mode, and FIG. 3 illustrates configuration of portable personal privacy screen system 200 into a freestanding portable personal privacy screen with oblong flexible panel 100 in an arched or folded (“taco”) mode and retained by a strap 205 coupled to opposing ends of arched panel 100.
Panel 100 includes a frame 105 defining a hollow oblong perimeter. A covering 110 engages frame 105 and fills the hollow. The type of material used for frame 105 and covering 110 is variable but share the requirement that they be flexible and allow panel to be transitioned between the flat and arched modes. For example, frame 105 may include spring steel or fiberglass that will not experience plastic deformation when panel 100 is transitioned to the arched mode of FIG. 3. Additionally, frame 105 preferably is stiff enough to quickly transition back to the flat mode from the arched mode when the restraining system is released.
Similarly, covering 110 may include a wide variety of material as long as it has minimal if any influence on panel 100 transitioning between modes. For example, in some implementations, covering 110 may include tear-resistant polyester or other material that may be made transparent, semi-transparent, translucent, and opaque. A film, fabric, netting, or other material may be used. Preferably the material resists tearing and puncture or is easily replaced or repaired.
In some implementations, covering 110 may be capable of supporting one or more patterns one or more of its surfaces (e.g., an obverse and a reverse or a front side and a back side, or the like). In some implementations, that pattern may be visible on one or both sides. For example, covering 110 that is semi-transparent may support a pattern visible when viewing either surface of panel 100. Covering 110 that is opaque may support different patterns on its two surfaces.
Panel 100, as illustrated, may be arched in either of two directions. As shown in FIG. 1, one direction includes moving ends of frame 105 “down” relative to moving a center portion “up”—this direction is further illustrated in FIG. 2 and FIG. 3. Panel 100 may in some cases also be arched in an opposite manner by transitioning the ends “up” relative to a motion of the center portion “down.” With covering 110 opaque, the user may determine which pattern is visible to which sets of viewers (e.g., a first set of viewers inside a privacy zone defined by the constructed portable personal privacy screen and another set of viewers outside this privacy zone).
Strap 205 cooperates with an attachment system 210 disposed at opposite ends of panel 100. The attachment system may include a buckle, a quick-release buckle, a snap, a tie down, a pin, or the like. Strap 205 includes a complementary coupler at each end that cooperates with attachment system 210 to releasably secure and retain panel 100 in the arched mode. In some implementations, a distance between the complementary couplers may be varied, which influences a degree of arching. That is, the longer this distance, the shallower is the arch. A steepest arch may be obtained when the ends of panel 100 in the arched mode are approximately perpendicular to strap 205.
Another factor influencing the degree of arching is a length of panel 100, which in turn is informed by a set of design goals which may include an age of a person intended for its use. An important dimension is a separation distance between ends of panel 100 in the arched mode. For many implementations, that distance should enable one or two intended users to comfortably lie side-by-side between the spaced-apart and retained ends of arched panel 100.
FIG. 4 illustrates an alternative embodiment for a portable personal privacy screen system 400 cooperatively configured using a sleeping system 405. Sleeping system at a minimum includes a sleep support 410 (e.g., a mattress) supported by a foundation 415 (e.g., a box spring). System 400 includes panel 100 and a retention system 420. In this case, use of a strap for retention system 420, while possible, would be unwieldly, therefore retention system includes a pair of retainers disposed between sleep support 410 and foundation 415. Each retainer 420 includes an engagement structure to capture and secure an end of panel 100 in the arched mode. FIG. 5 illustrates a close-up 500 of retainer 420 engaging an end of flexible panel 100. FIG. 6 illustrates installation of a pair of retainers 420 between sleep support 410 and foundation 415.
FIG. 7 illustrates a perspective view of retainer 420, FIG. 8 illustrates a top view of retainer 420, and FIG. 9 illustrates an end view of retainer 420. Retainer 420 may be configured as a U-shaped body 705 having a pair of free ends 710. At each end 710, a notch 715 and a hook 720 selectively and releasably engage ends of panel 100.
FIG. 10 illustrates an enhanced portable personal privacy screen system 1000 using system 400 as a base and further including one or more optional environment-influencing devices 1005 for use with an arched and retained panel 100. As illustrated, devices 1005 may include one or more curtains at a central lateral edge of arched panel 100 and/or a portable adjustable light that may clip on the central lateral edge. FIG. 11 illustrates a portable lighting system 1105 as an example of a type of environment-influencing devices. Other implementations may include additional or alternative devices, such as a sound or ambient noise device, a charging station for personal portable electronic devices, graphic display space, glow in the dark graphics (e.g., ultraviolet-responsive ink(s) or material(s)), a storage pouch such as for books, and the like. The glow in the dark may be implemented using luminescence, preferably fluorescence, and more preferably phosphorescence, examples of selectively-visible cold body radiation (e.g., provision of visible light without heating). In this context, the structure is selectively visible in that the illumination provided is not visible when a room or environment of the screen is illuminated (naturally or artificially). As the illumination dims, the glow in the dark structure becomes more visible but is not typically visible in fully illuminated environments. Some implementations may include structures having chemiluminescence in addition to or in lieu of the fluorescence or phosphorescence.
