Abstract

Collapsible discs move towards or away from each other in embodiments of the disclosed technology by changing the angle of flanges which connect the two discs together. The flanges connect to each respective disc by way of one a fixed connection to one disc and a slidable connection to the other. The flanges slide into portals in the bottom disc and then extend along and into a hollow space therein the bottom disc. The flanges have a tip or multiple tips which is/are wider than a rest of an elongated length thereof which frictionally holds the flanges, and therefore, the discs in places until the discs are rotated causing the flanges to be pulled out from or pushed into the portals. This, in turn, causes the discs to move closer together or become further apart in embodiments of the disclosed technology.

Description

FIELD OF THE DISCLOSED TECHNOLOGY

The disclosed technology relates to accessories which collapse, and more specifically, those that do so with sliding arms.

SUMMARY OF THE DISCLOSED TECHNOLOGY

A set of collapsible discs include a top and bottom disc. A plurality of individual flexible flanges extends from the top disc through respective portals in the bottom disc. Each of the plurality of individual flexible flanges extends further or less far into the respective portals in the bottom disc when the top and bottom disc are rotated relative to one another.

A "disc" is defined as "a device with a substantially circular most elongated plane thereof." The directions "top" and "bottom" are relative and interchangeable for purposes of this disclosure. In some embodiments, there is a horizontal line or plane of symmetry between the top and bottom halves of the device.

A "living hinge" is defined as "a flexure bearing which is flexible (changeable angle) and connects two rigid elements together in a way in which the rigid pieces can repeatedly (1000+ times) bend relative to one another and remain connected." Living hinges of embodiments of the disclosed technology are formed from thinned plastic material between disc and a part of a rotating hinge. In some embodiments, a disc, living hinge, and rotating hinge are formed together in a single mold. In some embodiments, two of such single molds are formed and a pin joins the rotating hinges together to form the collapsible device.

A "sliding hinge" or to be "slidably hinged" is to rotates a flange by having the flange move parallel along a length of an inset, cutaway, cavity, or portal in a disc changing an angle of the flange relative to the disc or discs.

The "discs" of embodiments of the disclosed technology have top and bottom sides which are elliptical and/or circular and interior space between the top and bottom sides which is hollow, filled, or partially filled and partially hollow. The hollow sections can have multiple tracks with elliptical or circular openings therein where each flexible flange passes into. The flanges can be fixedly or hingedly attached (such as by way of a flexural hinge) to the top disc and slidably attached to the bottom disc such that the flanges can flex (are flexible) and are resilient (able to change shape but return or substantially return or be shaped into a pre-changed shape without causing permanent or structural damage thereto).

The flexible flanges have ends, such as bulbous ends, which flare out or are wider at parts then a body thereof. The body, a longest part thereof can have a continuous cross-sectional shape and area (e.g. circular) while the tip, end, or bulbous end are a part which has a wider cross-sectional area which remains or tapers into an extreme end of each respective flange. The wider portion has a larger or equal cross-section than a track within the bottom disc and can be somewhat compressible (defined as "forces pressing there-against are able to shrink the cross-sectional area and the device is resilient"). In this manner, in a resting condition, the flanges remain in place relative to the bottom disc and the discs remain in place relative to each other. Twisting or rotating motion of the discs is required, in embodiments of the disclosed technology, to move the discs closer/further together while causing the flanges to be more inserted/more removed from the bottom disc.

Each end is circumferentially abutted against a respective hollow track within the bottom disc in some embodiments of the disclosed technology. Each respective portal extends into a track which bends in a curvilinear manner until becoming parallel with a top and/or bottom side of the bottom disc in embodiments of the disclosed technology. The plurality of individual (separate/spaced apart from each other) flexible flanges can be equi-distant from each other, such as at 120 degree increments arranged in a circular or equilateral triangular configuration.

The portal of the bottom disc through which a flange enters can be elliptical and non-circular. The two discs can rotate with respect to each other which causes the flanges to rotate and further enter or leave respective portals and hollow tracks within the bottom disc in embodiments of the disclosed technology. When rotating in a first direction, the discs get closer together and the flanges push into the bottom disc more, while when rotating in a second direction which is opposite the first, the flanges pull out of the bottom disc more than they were previously and the discs become further apart in embodiments of the disclosed technology.

Any device or step to a method described in this disclosure can comprise or consist of that which it is a part of, or the parts which make up the device or step. The term "and/or" is inclusive of the items which it joins linguistically and each item by itself. "Substantially" is defined as "at least 95% of the term being described" and any device or aspect of a device or method described herein can be read as "comprising" or "consisting" thereof.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSED TECHNOLOGY

Embodiments of the disclosed technology will become more clear in view of the following description of the figures.

FIG. 1 shows a translucent top and side perspective view of rotating and collapsible discs of embodiments of the disclosed technology. A top disc 10 and bottom disc 20 are spaced apart from each other in embodiments. At rest, the discs 10 and 20 are held in place relative to one another by way of a plurality of individual flexible, resilient, flanges 30. The flanges can each be substantially identical or be of different lengths and extend from and into a position which is equi-distant from a center point of a surface of the respective discs. The flanges 30 can also be equi-spaced from each other around a circle or at points of an equilateral triangle. In other embodiments, the flanges are unequally spaced from each other or from a center of a disc. The term "center" or "center-point", unless otherwise qualified, is defined as "at a center of an elongated top or bottom side of a disc." In this disclosure the terms "top" and "bottom" are relative to the direction of the paper in FIG. 3 where the top side of the sheet is the "top" side of the device, and each respective element within the device has a top and bottom side relative thereto. Thus, the top disc 10 is defined as being at the top side of the device and it's respective top side of the disc is the one which faces away from the respective bottom side of the top disc and away from the bottom disc 20 and so forth.

The flanges 30 can be fixedly and permanently (designed to remain connected and be irremovable without hindering functionality/effectiveness of the device as a whole) attached to the top disc 10 by way of an attachment 99. The attachment 99 can be by way of being procured in a single mold, printing, or construction or by way of a permanent fastening mechanism. The opposite end of the flanges 30 ends in a bulbous tip 32 or otherwise a tip which is defined by a part of the flange which has a cross-sectional area which is greater than that of a rest of the flange 30. The bulbous tip 32 can extend to end of the most elongated length of the flange 30 and be defined as such even if the extreme end is tapered, as shown.

FIG. 2 shows a bottom plan view of a bottom disc of the rotating and collapsible discs of FIG. 1. In this view the flanges 30 with tips 32 are shown being curvilinearly oriented and passing into respective elliptical portals 22 of the bottom disc 20. The elliptical portals can be non-circular or circular. A "non-circular" portal, for purposes of this disclosure, is one which has an eccentricity of at least 0.05.

FIG. 3 shows a side elevation view of the rotating and collapsible discs of FIG. 1 in an expanded condition. In the expanded condition the elongated length of the flanges 30 is most visible and outside of the bottom disc 20 with the bulbous tip 32 and only a small minority (less than 20%) of the flange length within the bottom disc 20.

FIG. 4 shows a side elevation view of the rotating and collapsible discs of FIG. 1 in a collapsing condition. Here, the flanges 30 are at least 40% inside of (surrounded by) the bottom disc 20 and more particularly, a hollow track 34. In this view, one can see the bulbous tip 32 abuts edges of the hollow track 34. The abutment can be on either side of the bulbous tip and/or circumferentially around all sides of the bulbous tip. The bulbous tip 32, as shown, is slightly compressed by the track 34. The friction between the tip 32 and track 34 prevents a respective flange 30 from moving within the track 34 when the discs 10 and 30 are at rest with respect to one another. Further, the friction in the track keeps the discs 10 and 30 at rest with respect to one another, but one can rotate the discs 10 and 30 with respect to one another to move the flanges 30 more in or out of the portal 22 and disc 30. Thus, by rotating the discs 10 and 30 in opposite directions from each other, one can either causes the flanges 30 to be further inserted or further removed from the disc 30 and the discs 10 and 30 to be moved closer or further way from each other as the flanges extend in a more vertical (top to bottom) or more horizontal (opposite of vertical) direction and become more curved with an inflection point moving up the flange(s) 30 as the discs are moved closer together.

FIG. 5 shows a side elevation view of the rotating and collapsible discs of FIG. 1 in a collapsed condition. Here, the majority or large majority (80%+) of each flange 30 is within the track 34 of the bottom disc 20 and the discs 10 and 30 are closest together.

FIG. 6 shows a solid top and side perspective view of rotating and collapsible discs of FIG. 1. FIG. 7 shows a bottom and side perspective view of rotating and collapsible discs of FIG. 6. FIG. 8 shows a first elevation view of the rotating and collapsible discs of FIG. 6. FIG. 9 shows a second elevation view of the rotating and collapsible discs of FIG. 6. FIG. 10 shows a third elevation view of the rotating and collapsible discs of FIG. 6. FIG. 11 shows a fourth elevation view of the rotating and collapsible discs of FIG. 6. These figures allow the viewer to see a completed version from the product from all sides. Note that the flanges are curvilinear and extend in a curvilinear manner into the portals of the bottom disc where, when pressed into the disc further, the flanges then extend horizontally across the disc in embodiments of the disclosed technology.

The covers can be identical or substantially identical where "substantially identical" is defined as having a same or substantially the same circular circumference of a most elongated or largest plane but having different depths and/or lips. For example, the top disc 10 can have a downward extending lip. That is, having different depths is still to be considered within the definition of "substantially" provided in the Summary of this disclosure.

Referring to all of the embodiments simultaneously, the devices can be procured out of two molds and flanges with a frictional end, slidable hinges, etc. The two molds can be identical or substantially identical (e.g. but for a lip or depth of a disc). Thus, a mold can be used to create a disc and flange together or separately with other such corresponding molds making up a bottom side thereof.

While the disclosed technology has been taught with specific reference to the above embodiments, a person having ordinary skill in the art will recognize that changes can be made in form and detail without departing from the spirit and the scope of the disclosed technology. The described embodiments are to be considered in all respects only as illustrative and not restrictive. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope. Combinations of any of the methods, systems, and devices described herein-above are also contemplated and within the scope of the disclosed technology.
