The patent to Szenay describes a carousel for storing and displaying compact disk albums or cases comprises one or more reels rotatably mounted on a turntable base where the reels include a central core and a pair of parallel spaced-apart disks having sets of parallel ribs disposed at equal angular positions around the core. The dimensions are such that the CD case readily fits between the pair of disks and are held upright by their engagement with the fibs formed on the disks. When a reel populated with a plurality of CD cases is placed on the base, it may be rotated so as to bring the cases into view for selection of a particular recording for play.
Generally, the prior patents illustrate various tape and disk holders, including: rotatable holders in a “tower” like shape with complex constructions and parts; holders for small audio cassette tapes no conducive to injection molding processes; holders that are small and portable that have various elements for actually “holding” items; various holders that do not rotate; and various merchandise display racks for usage in store and retail outfits.
Unlike the above, the present invention is a rotatable display system, including at least one rotatable display holder (“holder”). The holders are stackable for compact storage of large numbers of media items, as defined and used herein. The holder construction is cylindrical, with an axial center from which extends top and bottom disc-like surfaces, forming an open and accessible internal cylindrical volume. The internal volume is divided to realize media item compartments for insertion/extraction of media items, and empty compartments or openings on either side. The media-item compartments are preferably constructed so that its length (radial length) is less than the “insertion length,” or actual length of the media item, which supports that the user can readily grasp/insert, in a convenient and comfortable manner, any media item for storage and retrieval.
When used herein, or in the claims, media item should be understood to mean any type of rectangular object relating to media, such as containers holding computer-readable media such as CD's, or DVD's, or some combination of CD's and DVD's or VCR tapes, or boxes for VCR tapes, or some combination of VCR tapes, and DVD's or VCR and CD, or a combination of the three, or video games, hooks, etc., or some combination of any media item mentioned, or any media item known to those skilled in the art (hereinafter referred to broadly as “media items”).
The holders may include multiple sleeves or dividers to support definition the media-item compartments and open compartments to divide the internal volume. The dividers may be fixed in the slots or grooves, or may be slideable, or flexible, preferably a divider portions proximate outer portions of the holder construction. The dividers are preferably durable plastic material. Moreover, each holder of the rotatable display system rotates about its bottoms surface, which is constructed for stacking upon holder top surfaces. The media items are preferably stacked in the adjustable-sized compartments such that the user can easily read the title of each on the spine of the item. The holders may be constructed to include handles for carrying, and for stacking one upon another in order to store, and provide for the ready and convenient retrieval of the stored media items in an aesthetically pleasing manner.
As noted above, the present invention includes, among other things, a rotatable display system comprising rotatable display holders for storing media items such as VCR tapes, DVD's, video games, CD's, in compartments formed in an internal volume of the holders.
The rotatable display system includes one or more cylindrical rotatable display holders constructed in a preferably injection-molded design, for storing multi-media items. One feature of the inventive construction assures that a user may view the entire contents of a collection of multimedia items by spinning the holder, and easily and readily grasp or insert the media items into compartments within the holder, in a compact, elegant design.
The rotatable display holder (“holder”) is cylindrical with an axial center from which extends top and bottom disc-like surfaces. The construction forms an open and accessible internal cylindrical volume divided in such a way that there are compartments for insertion/extraction of stored media items, with openings or open compartments on either side. The compartments are preferably constructed so that the radial length of the media-item storage compartments is less than the “insertion length” of the media item. The inventive holder and rotatable holder systems provide that the user can readily grasp/insert, in a convenient and comfortable manner, any media item for storage and retrieval.
The holders may include multiple sleeves or dividers to support definition the media-item compartments and open compartments to divide the internal volume. The dividers may be fixed in the slots or grooves, or may be slideable, or flexible, preferably at divider portions proximate outer portions of the holder construction. The dividers are preferably durable plastic material, and are rotatable about their bottom surfaces. The bottom surfaces are constructed for stacking upon holder top surfaces. The holders may be constructed to include handles for carrying, and for stacking one upon another in order to store, and provide for the ready and convenient retrieval of the stored media items in an aesthetically pleasing manor.
When used herein, or in the claims, media item should be understood to mean any type of rectangular object relating to media, such as containers holding computer-readable media such as CD's, or DVD's, or some combination of CD's and DVD's, or VCR tapes, or boxes for VCR tapes, or some combination of VCR tapes, and DVD's, or VCR and CD, or a combination of the three, or video games, books, etc., or some combination of any media item mentioned, or any media item known to those skilled in the art (hereinafter referred to broadly as “media items”).
In one embodiment, the holder(s) are constructed as cylindrical structures (preferably injection-molded) that include an axial member defining a cylindrical central axis, from which round, substantially disc shape surfaces extend. An annular wall defining an inner dimension of the internal volume of the cylindrical structure is found at a distance R1 from the axial center.
While open, the internal volume is defined by the distance between surfaces (height), and the difference between the outer contained edge, at distance R2 from the axial center, and R1. Vertical dividers may be included between the inner faces of the top and bottom surfaces to extend radially from the axial center separating the internal volume into separate spaces or compartments to receive the media items. In this embodiment, the dividers may slide left or right to adjust the volume or shape of a compartment formed with the divider(s). This way media items may be easily inserted and removed. The dividers may extend from the axial center, to a position near, a position at, or a position in radial extension beyond the edge of the top, or bottom surfaces. The dividers may merely separate an outer portion of the distance from the radial center to the edge.
Alternatively, there may be an annular wall at a first radial dimension R1 of the holder (the dividers are not attached or formed to extend from the axial center), to which the dividers are attached, or formed as part of the structure by an injection-molding process, wherefore the dividers extend from R1 to an outer radial dimension R2 at the edge of the holder. The reader should note, however, that the dividers shown are situated in fixed slots, and have a fixed size, so must be quite flexible for sufficient comfortability for a user to move aside the divider with his/her fingers to grasp a media item placed therein. The invention contemplates that an empty compartment on at least one side of compartment should not contain a media item to allow for the intrusion into that compartment to facilitate placement and grasping.
The invention does not require the slots or grooves for insetting the dividers, but should be included in embodiments where the dividers are movable, for insertion into various slots or grooves to vary the size of the compartments, and empty compartments or openings. In this way the user can adjust the storage compartments to accommodate various-sized, and unconventionally-sized media items. Fixed media-item compartment size, or fixed number of compartments in a particular adjustable embodiment of the invention is not necessary as long as the dividers effectively and adjustably separate media items in the holder, and allow the user to effectively and efficiently, and comfortably grasp a stored media item, or insert an item for storage.
This arrangement provides that the individual dividers can slide into the upper and lower grooves, or tray be vacant from a groove giving the user even greater flexibility in defining his/her compartment sizes (volumes), particularly if attempting to store a non-standard size media item. Once a media item is inserted into a holder in a rotatable holder system, the user can easily read the title of each on the spine of the item. The compartments are flexible, not just for the ability to utilize or not utilize dividers in the slots or grooves, but the dividers themselves, because constructed with preferably flexible plastic, provide some “give” so that the user can easily place his or fingers round the media item. e.g., tape or DVD, etc., to conveniently pull the item from the holder.
In another embodiment, the holders may include dividers that are part of, and extend from surfaces in the holder construction. The “fixed” vertical dividers may or may not extend to full height of the compartment to be contiguous with the inside surface of the top cover, or any full length. There are limited only by their primary function, which is to divide the internal volume. As such, an aspect of the invention is to hold media items of different sizes, including CD's, DVD' movies and games, and VCR tapes, all of varying width and sizes. There is no set size, or set arrangement. The user can slide in all VCR tapes, or all CD's, or all DVD's (DVD movies, DVD games, DVD or CD computer software), or some combination thereof. The rotatable holder is perfect for a mish-mosh of various sized media items, because its inventive construction allows it to hold whatever is convenient, as long as it allows easy accessibility of the contents of the holder or holder system by merely spinning the rotatable holder (like a lazy Susan), but being able to readily grasp the media item. The holders are stackable, and may be placed in a cabinet wall unit or entertainment center.
The rotatable holder may be produced in several sizes. The holders can be stacked on top of one another to hold a large collection of tapes, DVD's and games. In addition, the rotatable holder may be motorized. The motorized rotatable holder system may be remotely control controlled. This allows the user to spin the holder to easily locate a particular item contained within. Finally, specialized cabinets may made for the rotatable holder, providing a compact means to hold a variety of items in an attractive manner.
Accordingly, it is an object of the invention to provide a rotatable system that includes rotatable display holders that effectively hold any media items in a space-saving manner, and which allows versatility in the user's storage arrangement, in view of stackability of the holders, in a light weight, a readily manufacturable plastic construction. The invention envisions that any divider used to divide internal volume into compartments is flexible, and slideable or movable about the surface or surfaces to realize adjustable compartment or slot sizes. That is, the holders may be made in one piece by injection molding, so costs are low and the rotatable holder system may be marketed at a very low price, and the stackable design.
Another object is to provide a system and holder that is manufactured of lightweight, relatively inexpensive material, functioning to keep manufacturing and shipping costs to a minimum, and each holder includes a handle. Preferable the handle is recessed into the top surface of the holder including the handle.
Furthermore, it is a goal of the present invention to provide a system or holder that is manufactured in any size, to contain any combination of media items in various numbers, for example, holders constructed in small and large sizes.
It is an additional goal of the invention to provide a system or holder that can include graphics thereon, as well as many colors thereon.
It is therefore an object of the invention to realize a rotatable display holder system includes one or more rotatable display holders constructed for stacking upon other rotatable display holders to store and display media items for easy access. The holders are preferably formed by injection molding by common materials to minimize cost. The holders may be formed as round, cylindrical housings, constructed with substantially flat upper and lower disc-like surfaces extending radially from the housing's axial center to create an open internal volume extending from an inner annular wall of the cylindrical housing at a distance R1 from the axial center to an outer edge of the cylindrical housing at a radial distance R2 from the axial center. R2 is determined so that a portion of intended media items extend from the edge of a compartment into which it is placed, and to define an outer boundary of the housing's annular internal volume.
A set of vertical dividers arranged on an inner face of at least one of the top and bottom disc-like surfaces, extending radially in a direction from the axial center to define boundaries of media-item storage compartments within the internal volume, and open compartments proximate each media storage compartment to facilitate grasping of media items stored in and partially extending from the storage compartments. The dividers are preferably flexible plastic, in order that they flex or slide with applied force by a user in order to access media items which may be stored therein.
It is another object of the invention to provide a rotatable holder that may be powered and remotely controlled, allowing the user to cause the holder to rotate to view all contents thereof.
Finally, it is an important goal of the present invention to provide media-item holders that can be easily stacked on top of one another, providing the user with a convenient means to store au entire collection of movies and games in a compact manner. Where the holders are injection molded, limitations may be imposed, but should not limit the breadth and scope of the inventions as claimed broadly. For example, the cylindrical housing, including dividers in whatever form and structure implemented to realize storage and non-storage spaces or compartments, is preferably formed as one structure, where rotate means is constructed separately to be attached to the housing for rotating operation.
The novel features which are considered characteristic for the invention will be set forth in the claims when submitted. The invention itself, however, both as to its construction and it method of operation, together with additional objects and advantages thereof, will be best understood from the description of the embodiments to be submitted when read and understood in connection with drawings relating thereto.
a) is another embodiment of a rotatable holder system of the present invention constructed to store exclusively DVD items, or containers sized accordingly, shown for the purposes of example only; and
b) is another embodiment of a rotatable holder system of the present invention to store exclusively VCR tapes, or containers, shown for the purposes of example only.
The single rotatable display holder is shown in the
As should be readily apparent, the inventive holder includes multiple open or non-occupied spaces or compartments (30) disposed between the media-item compartments to hold the media items, separated by a vertical dividers 19 of a set of vertical dividers positioned about one or both surfaces and extending radially with respect to the axial center. The reader should note that while the embodiment depicts dividers 19 in a functional form as shown as solid contiguous wall-like structures, any form of a divider, vertical, partial, or otherwise, which allows for fixed or adjustable separation of compartments within the internal or annular volume comprising the holder, as understood by the skilled artisan may be used without departing from the scope or spirit of the invention.
The designation of compartments 18, 22 and 26 for storing particular media items, such as VCR tape 20, DVD movie 24 and DVD game 28, separately with only one type media item, or a mixed fare of media items, are for example only. That is, compartments 18, 22 and 26 may be constructed to store all VCR tapes, or all DVD movies, or all DVD games, or any combination of the media items, and are only shown in the particular embodiments to give the reader a “feel” for the functional nature of the compartments, and the relationship between the open or non-occupiable compartments, and the media-item containing compartments. The only limitation for any storage compartment for use herein is that it have a length that is less than the media item, and preferably one inch less, and include open compartments or spaces on either side or the compartment defined by the divider or dividers, to allow the user finger space allotted thereby to easily and readily grasp same item.
The extra space provided between stored media items allows a user to conveniently place his or her fingers between the tapes or games to grab the same and pull them out of the compartments with ease. For that matter, the radial dimension which defines the radial length of the media-item compartment must always be less that the length of the media item intended for insertion and storage in said compartment, in order that some portion of the media-item extends or protrudes beyond the cylindrical edge of the internal housing volume, further facilitating easy and ready insertion and retrieval of media items.
When used herein, or in the claims, media item should be understood to mean any type of rectangular object relating to media, such as containers holding computer-readable media such as CD's, or DVD's, or some combination of CD's and DVD's, or VCR tapes, or boxes for VCR tapes, or some combination of VCR tapes, and DVD's, or VCR and CD, or a combination of the three, or video games, books, etc., or some combination of any media item mentioned, or any media item known to those skilled in the art (hereinafter referred to broadly as “media items”).
In general, the holder may be manufactured in any of a variety of durable materials that accomplish the purposes of the invention. Preferably, the holders are constructed of a durable plastic material by an injection molding process, which is envisioned by the inventor hereby. The surfaces of the holder are designed to facilitate injection-mold production, by the inventions' simple, elegant design. Each of the compartments (18, 22, 26), or any other compartments to embody alternative embodiments to those shown and described herein are intended to be constructed with dimensions that qualify an intended media item to be stored in a particular component, including defining each media-item compartment width such that it will readily accept deposit of, and ready retrieval of, media items, e.g. VCR tapes, DVD movies, games, etc., using only gravity and an accurate fit widthwise and height wise.
That is, the holder designs stay within the scope and spirit of the inventions as claimed if the each media-item compartment is constructed to be vertically oriented, and preferably adjustable at its flexible opening to receive media items, and provide the user with an ability to read on the spines of media items inserted therein. Compartments (18) as shown are of a width approximately 1¼ inches, and of sufficient depth to allow portions of the VCR tapes inserted therein to extend beyond the periphery of the housing up to one (1) inch. A second compartment size for such embodiments (22, 26) is depicted having a width of approximately ¾ inches, an of a sufficient depth to allow portions of the DVD's and video games inserted therein to extend beyond the periphery of the housing, up to one (1) inch.
Because the bottom (14) of the holder (10) is equipped with a rotatable assembly (16), the entire housing may be easily rotated by the user to display all contents of the holder. Such rotatable assembly (16), in the embodiment shown, comprises multiple annular members which function to both engage the holder flat bottom surfaces or bases, and to allow the user to spin the holder freely either manually or automatically (if the rotatable assembly is motor driven). In a simpler form, the rotatable assembly may comprise a base member that the holder is positioned, whereby the holder is able to be spinned about its central axis by force from a users hand(s).
While as mentioned above, the media-item compartments in the example (18, 22, 26) are of sufficient depth to allow portions of the media items inserted therein to extend beyond the housing, they are also sufficiently spaced apart from one another to create spaces therebetween (30). Such spaces (30) allow the user to easily place the user's fingers around the media item to pull it from the holder. It should be noted that the rotatable holders (10) may be manufactured in a variety of sizes to hold varying quantities of media items. The
In the next embodiment, the holder (10) is large in nature and comprises compartments to hold 16 DVD's and 16 VCR tapes. For the purposes of example, this small embodiment may be of a diameter of approximately 20 inches, but may still be of a height of approximately 8½ inches. In another embodiment, the holder may be small in nature and designed to hold only VCR tapes, and in a fourth embodiment the holder may be large in nature and designed to contain only VCR tapes, such as a quantity of 30 total VCR movies. Likewise, in vet another embodiment, the holder may be small in nature and designed to hold only DVD's, and in still yet another embodiment, the holder may be large in nature and designed to contain only DVD's.
Importantly, in each of the above examples, the holders may be designed to be stackable atop one another and rotate. For example, as illustrated in
Similarly, users with collections that include a mix of media items, such as VCR tapes, DVD movies and DVD games, may stack different embodiments of the present invention atop one another, such that the user can store and display their entire multi-media collection through usage of the holders.
Moreover, unlike the holders of the prior art, the rotatable holder of the present invention can hold a mix of media items, such as VCR tapes and DVD's or games, saving a great deal of space for the user. In fact, the rotatable holder can the placed in a cabinet with shelves for VCR's or DVD players, as well as in a wall unit or entertainment center. Such cabinets may be specially manufactured for usage in conjunction with the holders of the present invention, such as by including sufficient width and height for several such holders to be placed therein.
Regarding further versatility of the present invention, the rotatable display holder for media item storage, such as VCR tapes, DVD's, and video games, may be motorized, as illustrated in
In addition, in an enhanced alternate version, the rotatable display holder with adjustable openings may be customized by a user and able to be adapted to a user's particular needs. Such may be accomplished by the user inserting dividers in the multiple, available slots to create compartments of a desired size. For that matter, rectangular sleeves may be arranged between dividers, defining a media-item compartment by the sleeve, and opening on both sides bounded by the dividers. Fixed vertical dividers may be implemented in the inventions by embodiment shown in
The grooves or other means for holding the dividers can be arranged in a spoke or radial pattern as shown in
b) depicts an embodiment of a rotatable holder as described herein. Further including a handle 11. Alternatively, the handle may be detachable, or recessed. To that end,
Therefore, in total, the present invention provides a unique means to conveniently store collections of a variety of movies and games in a compact and aesthetically pleasing manner that provides users with ready insertion and access to media items stored therein.
With regard to all descriptions and graphics, while the invention has been illustrated and described as embodied, it is not intended to be limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled it the art without departing in any way from the spirit of the invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can readily adapt it for various applications without omitting features that, from the standpoint of prior an, constitute essential characteristics of the generic or specific aspects of this invention. What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
