Abstract
A device for storing compact disks comprising a base and a stack of supports installed on the base and placed one above the other. The supports have seats for compact disks, located one above the other. The device is made so that these seats can be pulled out from the stack by rotating the supports about an axis located outside these seats. The device has a retaining member connected with the base and located along said axis. The retaining member makes contact with the supports in their initial position, with the capability of resting, which restricts their rotation. The two supports that are immediately adjacent to each other make contact with parts of the retaining member and can stop, thereby restricting rotation of these supports in mutually opposite directions. Accordingly, the possibility of undesired pullout of adjacent supports from the stack following pullout of a compact disk is eliminated.

- Pertinent Art. The invention is a device for storing compact disks that is designed for storing flat articles, in particular optical media such as CDs, DVDs and/or Blue-ray disks.
- Prior Art. Devices for storing compact disks are known. The closest to the claimed invention are devices that provide compact disk storage in a horizontal position on flat supports—flat in the sense that their horizontal dimensions are much larger than their vertical dimensions—that are stacked (i.e., on top of each other) with upper supports resting on lower ones. The supports have holes on the axis located outside the seats for placement of compact disks. The seats can be pulled out from the stack when they rotate about a post placed in the holes. Examples are inventions U.S. Pat. Nos. 6,502,703, 6,193,061, 5,779,037, 5,232,275, 4,998,618, 5,344,028, 5,099,995, and 6,691,875. This design makes it possible to remove any compact disk from the stack without removing other compact disks. It has minimal horizontal dimensions so it does not need a lot of room on the support surface and does not take up a lot of space due to the small width of the supports. A common feature of these designs is that their lower supports carry the weight of their upper supports, so that there is friction proportional to this weight between the supports. Therefore, when one pulls out a support from the stack (i.e., “pull out the part of a support with the seat for a compact disk”), friction transfers the applied force to the adjacent supports, resulting in pulling the adjacent supports out from the stack. This creates an inconvenience for the user because the adjacent supports must be pushed back. To avoid this inconvenience, the devices use elastic members to retain the supports. For instance, in U.S. Pat. No. 5,697,684 the retaining member is a post that interacts with the supports by means of intermediate elastic members. Each member is rigidly connected with the post, and its protrusion makes contact with the groove on the post without restricting the rotation of the post. A shortcoming of this retention method is that the action of the retaining member on the supports does not preclude the likelihood of rotation and occurs on a small arm limited by the dimension of holes in the supports. In U.S. Pat. Nos. 2,429,290 and U.S. Pat. No. 5,813,740, retention is simpler and more reliable because the retaining member acts on elastic members of the supports that are moved away from the axis of rotation to opposite sides of the supports. Furthermore, in the last two example, as well as in U.S. Pat. Nos. 2,775,498, 3,392,868, 4,815,483, 5,099,995, 5,516,203, 5,524,976, 5,779,037, 6,626,306 and 7,370,758, because the supports stop against members of the devices, the supports are made so that they can rotate only in one direction from the initial position.
- U.S. Pat. No. 5,813,740 is the closest to the claimed design. In this device, the supports are placed horizontally, and the compact disk seats are pulled out from the stack by rotating the supports in the same direction while overcoming the resistance of the retaining member which acts on the supports' elastic members, and thus keeps the supports in the stack. The rotation of the supports in the opposite direction is limited because they stop against members of the devices. Thus, when a support is pulled out, the retaining member acting on the elastic members of the adjacent supports keeps them from rotating. To make this retention more reliable, the elastic member has a braking engagement with the retaining member. To disengage the elastic member, a user can bend the elastic member (pressing the member end with a finger). When the support is rotated back, the adjacent supports rest against members of the device and therefore remain in the stack. This design ensures reliable and accurate retention of the supports, but makes use of the device less convenient. Firstly, retaining the supports in the stack, by means of elastic members, and keeping them from rotating with the support that is being pulled out is not sufficiently reliable when the extent of engagement with the retaining members is low. It may also requires additional effort by the user to disengage the elastic member. Secondly, the user only has access to the supports on one side of the device—the side where the supports are pulled outward—as opposed to, for instance, the device in U.S. Pat. No. 5,697,684 in which the supports are not limited to rotating on one side.
- Disclosure of Inventions. The objective of the invention is to make a device for storing compact disks more user-friendly by saving the time and effort the user needs to find and retrieve the desired disk in a stack of supports. This is done by preventing the supports adjacent to the support being pulled out from also being pulled out.
- The essence of the invention is expressed in the following combination of features:
-
- the device for storing compact disks comprises a base and a stack of supports;
- the stack of supports is installed on top of the base;
- the supports are placed on top of each another, with upper supports resting on lower ones;
- the supports have seats for compact disks;
- the device is made so that said seats can be pulled out from the stack by rotating the supports about the axis located outside the seats [the design features that make it possible to rotate the supports are not essential because they do not affect any technical result; this capability can be provided by links that limit the movement of the supports about the axis of rotation—either between the adjacent supports as in the example of the device embodiment shown below, or between the supports and the post placed in support holes that are concentric with said axis, i.e. traditionally, like in the above analogues];
- the device has a retaining member which is connected with the base, placed along said axis and makes contact with the supports in their initial position, with the capability of stopping, which limits said rotation; the nearest, i.e. the two adjacent supports, make contact with parts of the retaining member, with the capability of stopping, which limits the rotation of the supports in mutually opposite directions.
- Thus, due to this stopping, the adjacent supports can only rotate in mutually opposite directions from the initial position. Therefore, when a support is rotated from its initial position, the adjacent supports above and below it will stay in the stack despite the fact that they are acted upon by friction from the support being pulled out, which means that all other supports will also stay in the stack. The proposed solution, due to the stopping, prevents the supports adjacent to the support that is being pulled out from also being pulling out from the stack; however, the stopping does not prevent these supports from being pulled out when the pulled-out support is rotated back into the stack. On the contrary, in the above analogues where all supports are only capable of rotating in one direction from their initial position, the supports adjacent to the pulled-out support cannot be pulled out when the pulled-out support is rotated back because of the stopping at the device members, but these supports are not prevented from being pulled out when the support between them is pulled out.
- The technical result (positive effect) of the invention is the complete elimination of the capability of pulling out adjacent supports from the stack when the support between them is pulled out. From this result follows another technical result, namely, saving a user's effort and time needed to prevent undesired pullout of adjacent supports by holding them in or returning them back. This result is achieved because the rotating support does not impede said corrective actions because they are performed on the other side of the stack. The use of elastic members for additional retention of the supports reduces the likelihood of undesired pullout of adjacent supports in both solutions. If one compares the embodiments of the devices in U.S. Pat. Nos. 5,813,740 and 2,429,290, wherein the user is forced to directly act upon the elastic member to disengage it, the embodiment of the claimed invention described below wherein an elastic member is used to retain the support does not require such action. One can see another technical result, namely, saving a user's time and effort needed to pull out a compact disk from the device. This technical result is achieved because the need to act on the elastic member arises every time a support is pulled out, but there is less of a need for corrective action—the need only arises when the friction that pulls the adjacent supports exceeds the force of resistance of the elastic members. Since the supports are made with the capability of pulling out compact disk seats from the stack by rotating them in both directions, another technical result of the invention is the increased space for a user's access to the supports. Because of this, it is possible to place components of the supports designed for gripping or marking on both sides of the device, to make them larger and place them farther from one another so they do not interfere with each other. This will lead to another technical result, namely, reduced time for retrieving the required compact disk.
- In a preferred embodiment, at least one of the two supports adjacent to a support between them has a rest member protruding toward the second support with the capability of resting against it, which limits the movement of the two supports toward each other. When a support is pulled out from the stack, the adjacent support above it drops down into the space that has been freed and rests on the lower adjacent support. In the case where at least one of the two adjacent supports has a rest member protruding toward the second support, this member takes up part of the weight of the supports above, thus reducing the weight load on the pulled out support. The technical results are reduced friction between the pulled out support and the two adjacent supports, and reduced force to pull out the support. Another technical result is achieved when the pulled out support is returned to the stack, namely, a reduced likelihood that the supports adjacent to the support being rotated will be extended because the friction that might cause such extension is lower. In the preferred embodiment, said rest member of the support is made in the form of a rest shoulder that bounds the support on the side where it is pulled out from the stack.
- In the preferred embodiments, the edges of the rest shoulders that are farthest from the axis of rotation are capable of contact with the retaining member of the device; the rest shoulders of the supports are made protruding upward.
- In a preferred embodiment that provides more accurate retention of supports by acting on them at the longest arm, the retaining member makes contact with the outside surfaces of the supports that are moved away from the axis of rotation in the direction of the compact disk seats.
- In other preferred embodiments, in order to additionally retain the supports in the initial position and reduce the likelihood of adjacent supports being pulling out from the stack when the support between them is rotated back to the stack, the supports have elastic members that make contact with the retention member in the initial position of the supports and can deform elastically when acted upon by the retaining member. One end of the elastic member is connected with other parts of the support, and its other free end protrudes from the connected end in the direction of its extension from the stack. In the initial position of that support in the stack it makes contact with the retaining member. The free end of the elastic member of the support has a shoulder that makes contact with the retention member on the side of said axis, with limited movement away from the axis. The elastic member of the support has two parts pulled out along each other from one end of the elastic member to the other and connected with each other only at these ends.
- In another preferred embodiment of the retention member, the supports have holes along said axis. The retaining member is placed into those holes, and is made as a post that has at least one longitudinal groove. The supports have radial protrusions directed inside the holes and placed in the groove with the ability to interact with the groove edges, wherein, in the initial position, the radial protrusions of the adjacent supports make contact with different edges of the same groove.
- In a preferred embodiment, in order to limit the rotation of the supports in the pulled-out position, the length of said groove in the circumferential direction, as well as a the dimension of the radial protrusion of the support in the same direction, are made so that the protrusion can rest against the second edge of the groove after the angle of rotation of the support is sufficient to pull out the compact disk from the support.
- In a preferred embodiment, the post has two grooves, and each support has two radial protrusions, each placed in one of the grooves.
- There are two other—alternative—versions for placement of the retention member that also provide a solution for the stated objective. In the first version, the retaining member makes contact with the outside surfaces of the supports when moved away from said axis in the opposite direction from the compact disk seats; in the second version, the supports have holes along said axis, the retaining member is placed into those holes, and said axis is located outside the holes.
- In preferred embodiments, in order to make using the device more convenient by reducing its space, the supports are made with the capability of placing compact disks in them on the same axis parallel to the supports axis of rotation. The retaining member has a longitudinal axis parallel to and placed in the same plane as said axes. The retaining member is made in the form of a round rod, and said axes are placed vertically.
- In preferred embodiments, in order to make the device more convenient for use by improving access to the supports, the supports have handles for gripping that are rigidly connected with the rest shoulders of the supports and protrude outward from the supports in at least two vertical rows, and in four vertical rows in a preferred embodiment. The handles are made in the form of plates and placed with their outward protruding edges tilted downward.
- Due to this stop, the possibility of undesired pullout of the adjacent supports from the stack following the pulled out support is eliminated.
- A device for storing compact disks, intended for storing flat articles, particularly optical media, comprising a base and a stack of supports installed on the base and placed one above the other, with upper supports resting on lower ones. The device eliminates the possibility of undesired pullout of adjacent supports from the stack following the pullout of a compact disk from the stack. The supports have seats for compact disks, located one above the other. The device is made with the possibility to pull out these seats from the stack by rotating the supports about an axis located outside these seats. The device has a retaining member connected with the base and located along said axis. A retaining member makes contact with the supports in their initial position, with the capability of resting, which restricts their rotation. Herein, the nearest supports, i.e., the two supports that are immediately adjacent to each other, make contact with parts of the retaining member with the capability to stop, which restricts rotation of these supports in mutually opposite directions.

Device 1. To place acompact disk 10 into thedevice 1, a user can use one hand. To do this, he first secures thecompact disk 10 on asupport part 58 of the retainer on thecover 50. Then, the user selects ahandle support support 100. In this case, he can take a marker from acup 65 and write acompact disk 10 title or symbol on thehandle 110. Then, the user acts on thehandle 110 with his hand, directing force to his left. This force is transferred to amiddle ring 120 and anannular shoulder 140 ofsupport 100. The outer surface of themiddle ring 120 interacts with the inside surface of theannular shoulder 240 ofsupport 200 adjacent below, and the inner surface of theannular shoulder 140 interacts with the outer surface of the middle ring 420 ofsupport 400 adjacent above. As a result,support 100 starts rotating clockwise about axis L1. The side surface of anend bridge 173 of anelastic member 170 ofsupport 100 acts on apost-retainer 6. Because the radial component of this force is directed toward axis L1 of rotation of the support, theelastic member 170 ofsupport 100 bends in a horizontal plane, and its free end moves toward axis L1. In the process, the outer surface of the externalelastic part 171 of the elastic member is pressed against and slides along apost-retainer 6. In this, the force of friction fromsupport 100 acts on itsadjacent supports support 100 that is being pulled out and to rotate them clockwise too. The force is transferred to the rest bridges 276 that face thepost-retainer 6; they are located on the front ends of the rest shoulders 203 of thesesupports post-retainer 6. Because of this, supports 200 and 400 stay put. Assupport 100 rotates, free space is formed in its place. Under the weight of the supports located abovesupport 100, the upperadjacent support 400 moves down until the lower part of itsrest shoulder 203 rests against the upper part of therest shoulder 203 of the loweradjacent support 200. Thus, therest shoulder 203 ofsupport 200 takes on part of the weight of the first part of thestack 70. This reduces the load onsupport 100 that is being pulled out, and free space is formed under the upperadjacent support 400; the height of this space is equal to the height of the protruding upward part of therest shoulder 203 ofsupport 200. Further,support 100 rotates by an angle sufficient to remove thecompact disk 10 fromsupport 100. Side surfaces of theradial protrusions 151 ofsupport 100 rest against theedges 44 of the grooves of thepost 40 of thepost-cover 5, and this stops the rotation ofsupport 100. Then, the user takes thecompact disk 10 from asupport part 58 of acover retainer 50 and places it in its seat insupport 100, namely, on asupport pad 161, and retains it by placing its hole on aninner retention shoulder 162. When this is done, awide part 102 ofsupport 100 pulled out from thestack 70 is exposed to the action of the user's hand in the up-down direction, and the action of the weight of thecompact disk 10 and of its own weight. Each of these forces creates a moment on the arm equal to the distance from axis L1 to the line of its action. The sum of the moments of all these forces is counteracted by the moment from the action of the weight of the supports located above the support being pulled out from thestack 70 and of the reaction forces ofsupport 200 below it on the narrow part of the support being pulled out from thestack 70. If this counteraction is not enough to balance said sum of moments, for instance, when the support being pulled out is on the top of thestack 70 and the weight of the supports located below is not enough, the reaction forces of theupper hooks 241 of theadjacent support 200 below take effect. These forces act down on thelower hooks 131 ofsupport 100, keeping thenarrow part 101 ofsupport 100 from moving up. Further, by pushing thehandle 110 ofsupport 100 with his hand, the user rotatessupport 100 counterclockwise about axis L1, returning it back to thestack 70.Support 100 slides into thestack 70 and gets into said open space under theadjacent support 400 above, which rests against arest shoulder 203 of theadjacent support 200 below; therest shoulder 203 takes on part of the weight of the supports located abovesupport 100, and this reduces the friction force that impedes the sliding ofsupport 100 into thestack 70. Further, when sliding into thestack 70,support 100 acts, by means of friction forces, onadjacent supports stack 70. The action of the friction forces is transferred to theelastic members 270 ofsupports post-retainer 6 with their end bridges 273. The reaction of thepost-retainer 6 onsupports stack 70. Furthermore, the post-retainer 6 acts on the moving outside surface of theouter part 171 of theelastic member 170 ofsupport 100, sliding along it and bending theelastic member 170 in a horizontal plane. At the end of the return rotation ofsupport 100, theend bridge 173 of theelastic member 170 snaps behind thepost-retainer 6; acted upon by elastic forces, theelastic member 170 straightens, and itsstop 174 rests against thepost-retainer 6. - To remove the
compact disk 10 from thedevice 1, the user, as before, pulls out a support, for instance,support 100, using thehandle 110, and takes thecompact disk 10 with two fingers. Herein, the user can take thecompact disk 10 by its outer edge through theholes 106, or with one finger, for instance, his index finger. He can take thecompact disk 10 by the edge of its hole, and with the other finger, for instance, his thumb, he can take the compact disk by its outer edge. - The other supports—200, 300 or 400—comprise the same components as
support 100, which, when they interact with thepost 40 and the respective components of adjacent supports, work similarly to the components ofsupport 100. - The sequence of assembling device 1: assemble the
