This invention relates to holders for temporarily storing and displaying compact discs.
Compact discs are packaged, sold and stored in plastic Jewel boxes or cases made of plastic, paperboard, or a combination of plastic and paperboard. For long term storage, Jewel boxes containing the discs are stacked or filed in cabinets or stands positioned near the using apparatus, such as a computer workstation having a CD-ROM, or a stereo compact disc player. Maintaining the integrity and future unadulterated performance of the discs require that the information carrying surfaces of the discs not contact desk tops, tables, or other surfaces that may scratch the discs or from which or on which the discs may fall or be damaged. Users, however, have demonstrated an unwillingness to return the discs to their Jewel boxes after use, especially in situations where the contents of the disc may be performed again. Returning the discs to the correct Jewel boxes and correctly refiling the Jewel boxes is inconvenient and requires time that often is not available to the user. Removing discs from Jewel boxes also requires time and interruption. Users prefer to have the discs lying at their fingertips and are willing to sacrifice damage to the discs in return for rapid, easy access. Needs exist for holders for temporarily storing discs that are easy to use, that stably secure the discs and that prevent or limit surface contact with the encoded sides of the discs.
Existing storage and display holders do not provide for easy user identification and selection of the stored discs. The discs may be so deeply entrenched in the holder that visual identification is difficult. Additionally, by inserting a large percentage of the disc in the holder, the risk of scratching the recorded surfaces of the discs increases. Needs exist for storage and display stations that provide maximum visual access to the disc while still securely holding the discs in place.
Cost plays a major factor in consumer selection of storage and display devices. Consumers demand attractive items that are not only rugged and easily transportable but also that are reasonable in cost. Needs exist for storage and display stations that are appealing to consumers in both looks and price.
A one-piece molded transfer station offers a simple, quick and safe harbor for temporarily storing and displaying discs. The station is stable, provides the user with excellent visual identification of the displayed discs and is easy to use.
The present invention provides a safe means to store discs, when refiling the discs in Jewel boxes or catalogs is not appropriate. The station becomes a staging area for discs between use and storage and offers an attractive alternative to laying discs on a desk, table, cabinet or other surfaces. The present invention has applications in every instance where multiple discs are used, including parties and night clubs where disc jockeys continuously shuffle compact discs. The present invention is also economically attractive, as the station is manufactured from a one-piece mold.
Each station has a base that includes multiple rows pockets for receiving discs. The base preferably slopes upward from front to back and has curved front and back edges, thereby creating a "Grandstand" or stadium shaped station. Having that configuration, the discs extend progressively higher from front to back, thereby providing enhanced visual access to the identifying features of the discs. The rows of pockets are preferably staggered to permit better access and easier removal and insertion of a disc without contacting adjacent or surrounding discs. In one preferred embodiment, the station has four rows of pockets, with each row including four pockets. Preferably, the sides of the station have connectors, such as connecting feet, that permit identical stations to be connected to each side. That provides for multiple station assemblies and permits the user to create different size assemblies that are appropriate to meet situational requirements.
Multiple curved depressions extend from the front to the back in the upper surface of the base. The curved depressions extend through central regions of the rows of pockets and function to keep holder edges away from the recorded surfaces on the discs, to guide the discs into holding troughs and to permit horizontal movement of the discs once the discs have been slightly lifted.
The discs are securely held in generally vertical positions in the pockets. Each pocket has a generous lead-in for quick drop-off of a disc. At the bottom of the lead-in is a curved trough that is preferably about 0.045 inches deep. The lower portion of the disc sits in the trough. Although the sides of the trough contact the flat surfaces, or sides, of the disc, the trough never comes in contact with the information carrying or encoded region of the disc surface. The pockets are wider than the discs, thereby preventing interference and damage hazards associated with a tight fit. The walls and trough of each pocket may have reliefs for permitting the free flow of air or moisture out of the pockets.
Preferably, three small bumps are positioned in each trough for orienting the disc at an angle. Preferably, first and second bumps are positioned on the front surface of the trough and a third bump is positioned on the back surface of the trough between the first and second bumps. The curved trough makes the first and second front bumps higher than the third rear bump. That configuration urges an inserted disc to be tilted slightly backward, thereby providing the user with enhanced visual access to the identifying surface of the disc. The bumps ensure that the disc is consistently tilted backward and prevent forward tilting when the disc is touched or when the station is moved or bumped.
In a preferred embodiment, first and second bumps are positioned on either end of the front side of the trough and a third bump is positioned near the middle of the back side of the trough close to the bottom. The third bump pushes the lowest point of the disc forward. The first and second bumps push the front side, or encoded surface, of the disc backwards, thereby forcing the disc into a rearwardly-tilting position.
In another preferred embodiment, a rearward tilt of the disc is accomplished by molding a straight trough with walls having a desired angle of slope. That is accomplished by rotating the station in the mold so that the pockets are molded in the direction of draw.
The transfer station apparatus for storing and displaying compact discs includes a disc-receiving base having a front edge, a back edge, a left edge and a right edge. A support extends downward from edges of the disc-receiving base. The support may include a front extending downward from the front edge of the disc-receiving base and a back extending downward from the back edge of the disc-receiving base. Pockets for receiving compact discs are positioned in the disc-receiving base. Each pocket includes a first lead-in wall extending inward and downward from the disc-receiving base toward a center of the pocket, a second lead-in wall extending inward and downward from the disc-receiving base toward the center of the pocket, and a trough connected to and positioned between bottoms of the first and second walls for receiving lower sides and edges of the disc. The trough has dimensions for contacting non-recorded flat peripheral surfaces of the disc.
The pockets are preferably arranged in rows extending between the back edge to the front edge of the transfer station. In one preferred embodiment, pockets are arranged in first and second rows, and the pockets are positioned in a staggered configuration. In another preferred embodiment, the pockets are arranged in first, second, third and fourth rows, and the rows are staggered such that the first and third rows and the second and fourth rows are generally at the same level.
Each pocket preferably has a width that is greater than a width of a standard compact disc.
In one preferred embodiment, each pocket includes multiple bumps extending inward from the first and second walls for orienting a compact disc at a backward-tilting angle. The multiple bumps preferably include three bumps, with the first bump extending inward from a left side of the first wall, the second bump extending inward from a right side of the first wall and the third bump extending inward from a middle portion of the second wall. The third bump is preferably positioned at a lower portion of the pocket such that the third bump pushes a lowest part of a compact disc forward when the disc is filly inserted in the pocket. The first and second bumps extend inward at a position above the third bump for pushing a front, nonrecorded side of the compact disc backwards.
In another embodiment of the present invention, each pocket is a generally straight slot having the first and second walls extending downward at an angle substantially parallel to one other.
Curved depressions extend from the front edge to the back edge of the station in the disc-receiving base of the station. The number of depressions preferably equals the number of rows, with a single depression extending through central regions of the pockets in each row.
In a preferred embodiment, the back of the station is higher than the front, thereby causing the disc-receiving base to slope downward from the back to the front. The front and the back are preferably curved, with the front and back edges of the disc-receiving base curved to follow the front and back. The curved depressions follow radii of the front and back edges of the disc-receiving surface.
Preferably, the holder further includes sides extending downward from side edges of the disc-receiving base. At least one connector is preferably positioned on at least one of the sides of the holder for connecting multiple holders together. In one preferred embodiment, the connector is an anti-skid foot.
In a preferred embodiment of the present invention, the front includes a first part that slopes outward and downward from the front edge of the base and a substantially vertical part extending downward from a lower edge of the first part. The back includes a first segment that slopes outward and downward from the back edge of the base and a substantially vertical segment extending downward from a bottom edge of the first segment. The side walls extend downward from side edges of the base, with each side wall joining outer edges of the front and back walls.
These and further and other objects and features of the invention are apparent in the disclosure, which includes the above and ongoing written specification, with the claims and the drawings.

FIG. 7 shows a preferred embodiment of a pocket having three bumps for orienting a disc in a rearwardly-tilting position.
FIG. 8 shows another preferred embodiment of the present invention including a disc-receiving base having four rows of pockets.
FIG. 9 is a front view of the transfer station of FIG. 8.
FIG. 10 is a plan view of the transfer station of FIG. 8.
Referring to the drawings and to FIGS. 1-10, a transfer station 1 includes a front 3, a back 5 and a disc-receiving base 7 extending between the front 3 and the back 5. The disc-receiving base 7 has rows 9 of pockets 11 for receiving and holding lower parts of compact discs. Each pocket 11 preferably has a width that is greater than a width of a standard disc. There are numerous possible options for the number of rows 9, the number of pockets 11 in each row 9 and the positioning of the pockets 11 and rows 9, and the embodiments provided are only exemplary and do not serve to limit the possible configurations for the present invention.
FIGS. 1-6 show one preferred embodiment of the transfer station 1. The disc-receiving base 7 has a front edge 13, a back edge 15 and a pair of side edges 17, 19. The disc-receiving base 7 slopes downward from back to front such that the back edge 15 is higher than the front edge 13. That enhances visual identification of the discs and reduces size of the holder, while maintaining effective disc separation. Two rows 9 of pockets 11 are positioned in the base 7.
As shown in FIG. 2, the pockets 11 are staggered and the end regions 21 of the pockets 11 preferably extend between end regions 21 of pockets 11 from the adjacent row. That allows for a smaller, more compact transfer station 1. A curved depression 23 extends through central regions 25 of each pocket 11. Preferably, a single curved depression 23 extends through each row 9 of pockets 11 from the back edge 15 to the front edge 13 of the base 7. In embodiments where the back edge 15 and front edge 13 of the base 7 are curved, the curved depressions 23 follow the radii of the front and back edges. The depressions avoid contact with recorded surfaces and speed insertion and removal of discs.
As shown in FIG. 2, the back 5 preferably extends downward and outward from the back edge 15 of the base 7 and the front 3 extends downward and outward from the front edge 13 of the base 7. That configuration improves the stability of the station 1.
FIGS. 3 and 4 show preferred shapes for the front 3 and back 5 of the station 1. The front 3 includes a first part 27 that slopes outward and downward from the front edge 13 of the base 7. The first part 27 has curved parts 29 corresponding in position to the location of the curved depressions 23. A substantially vertical part 31 extends downward from the lower edge 33 of the first part 27. The back 5 includes a first segment 35 that slopes outward and downward from the back edge 15 of the base 5. The first segment 35 also has curved regions 37 corresponding in position to the location of the curved depressions 23. A substantially vertical segment 39 extends downward from the bottom edge 41 of the first segment 35.
As shown in FIGS. 3 and 4, preferred embodiments of the station 1 have sides 43, 45 extending from and connecting to side edges of the base 7, the front 3 and the back 5. The sides 43, 45 are preferably generally vertical.
As shown in FIGS. 1 and 2, when the front edge 13 and back edge 15 of the base 7 are curved, the base 7 becomes progressively wider from front to back. The front 3 and back 5 of the station 1 follow that defined curvature, and the back 5 therefore spans slightly wider than the front 3. The sides 43, 45 angle slightly inward from back to front to join the back 5 of the station 1 to the front 3 and to follow along the side edges 17, 19 of the base 7.
Connectors 49 are positioned on the sides 43, 45 for connecting multiple stations together. In a preferred embodiment the connectors 49 are ant-skid feet that engage apertures in the side of an adjoining station. FIGS. 3 and 4 show a preferred embodiment of the present invention having two pairs 51, 53 of connectors positioned on each side, with the pairs on one side including multiple feet and the pairs on the opposite side including multiple apertures for receiving the feet. Other arrangements, numbers and kinds of connectors are envisioned as possible.
FIGS. 5 and 6 are cross-sectional views of the station of FIG. 2 taken across central regions 25 of the pockets 11 of the adjacent rows 9. Each pocket 11 has a first wall 55 extending inward and downward from the upper surface 57 of the disc-receiving base 7 towards the center of the pocket 11 and a second wall 59, opposite the first wall 55, that also extends inward and downward from the upper surface 57 of the disc-receiving base 7 towards the center of the pocket 11. A trough 61 is positioned between and connected to bottoms of the first wall 55 and second wall 59 of each pocket 11. The trough 61 preferably has dimensions for receiving lower sides and edges of a disc and for only contacting non-recorded surfaces of the disc.
As shown in FIG. 2, and more clearly in FIG. 7, each pocket 11 has multiple bumps extending inward for orienting the disc in a rearwardly-tilting position. In a preferred embodiment, the trough 61 of each pocket 11 has a single rear bump 63 and a pair of front bumps 65, 67. The rear bump 63 is positioned near the middle of the back wall 69 of the trough 61. The two front bumps 65, 67 are positioned on outer edges of the front wall 71 of the trough 61. The rear bump 63 is also preferably positioned deeper in the trough 61 than the pair of front bumps 65, 67. That arrangement allows for the rear bump 63 to push a lowest, nonrecorded edge adjacent the recorded surface of a disc forward and for the pair of front bumps 65, 67 to push the front, nonrecorded surface of the disc backwards, thereby slightly tilting the disc backwards.
In another preferred embodiment of the present invention, the pockets 11 are straight slots having that are molded at an angle of preferred tilt or inclination.
FIGS. 8-10 show another preferred embodiment of the present invention having a disc-receiving base 7 that has four rows of pockets 11 and curved depressions 23 extending through central regions 25 of each row 9 of pockets 11. The base 7 is generally parallel to the supporting surface. The front 3 extends outward and downward from the front edge 13 of the base 7 and the back 5 extends outward and downward from the back edge 15 of the base 7. Both the front 3 and the back 5 each include a large part 73 that extends from the front 13 and back 15 edges of the base 7, respectively, and a smaller, generally vertical footing 75.
As shown in FIGS. 8-10, the station 1 has no sides. The front 3 and back 5 are curved, and the curved depressions 23 follow the radii of curvature of the front 3 and back 5 of the station 1.
While the invention has been described with reference to specific embodiments, modifications and variations of the invention may be constructed without departing from the scope of the invention, which is defined in the following claims.
