Description

SLIDE TYPE COMPACT DISC CASE

Background of the Invention

The present invention relates to a compact disk storage case used for computer software or music storage in which a compact disk can be inserted through an opening at one face, more particularly, to a sliding type compact disk storage case where a compact disk is stored by inserting one face of the compact disk into a groove formed on one face of a slide lever and on a disk holding bar located inside the storage case, and where the compact disk is retrieved through the opening at one face of the storage case by sliding the slide lever.

The present invention allows an easy insertion/retrieval of compact disk (CD) without inflicting damages to the surface of compact disk where data is stored. The present invention also provides a convenient way for a long-term storage of compact disks where important data is stored. The present invention has resolved some of the most prominent problems associated with the conventional storage cases that include damaging of the hinged sections during an opening/closing of the cover and scratching of the surface due to the difficulty associated in detaching the compact disk from a central retaining hub.

In general, a number of different types of storage cases exist which allow insertion/retrieval of a compact disk at one face.

KR Pat. No. 97-8649 describes a compact disk storage case which accommodates two compact disks. The storage case comprise a front cover portion, a rear cover portion, a portable portion that contains supporting members for each supporting two disks at two opposing faces of the portable portion and a pivot coupling member for a pivotal installation of the portable portion between the cover portions near the edges of one of the cases. The case when closed has almost the same thickness as that of a single compact disc storage case. The front portion, rear portion and portable portion are pivotally connected along the edges of one of the cases. The pivot-coupling member comprises a first pivot-coupling member that connects the front portion and rear portion along the edges of one of the cases and a second pivot-coupling member that connects one of the cover portions to the portable portion. The pivot center line for the second pivot member is parallel to the edges of one of the cases and also adjacent to it. The front and rear cover portions are in such a form that when the case is closed, the cover portion completely closes the edges of the portable portion.

Since the side face size of the portable portion is smaller than the face size of the corresponding front and rear cover, the edges of the cover portion stretches beyond the edges of the portable portion when the case is closed. The front cover portion, rear cover portion and the first pivot portion comprise pivotally connected front portion and rear portion of the standard compact disk cases for single compact disk with a missing fixed disk portable portion.

However, in the above configuration, the protruding front cover portion when opened for retrieving the compact disk, characteristically lies parallel to the portable portion where the compact disk is located. As a result, there is no risk for the front cover portion to be dislocated from the groove or the pivot portion of the front cover portion to be damaged.

KR Utility Model. No. 152432 describes a compact disk insertion retrieval case which comprises a tray where compact disk is to be placed. The tray is inserted/retrieved by sliding through the insertion/retrieval case. The engaging portion and extraction portion of the trays are formed in terms of grooves. A spiked elastic piece is formed at the front portion underneath the tray and a spring is placed in a spring jig at the rear face. Finally, a foundation spring groove is formed at the rear end portion. The above compact disk insertion/retrieval case has a ' ' shaped cross sectional configuration and forms an extraction groove. At the side face and lower face, a dislocation protection groove and a foundation groove are formed and at the rear portion form a spring foundation groove.

At the front face and lower face, multi-step locking holes and multi-step locking teeth are formed along a straight line to form a overlapping layer in order to function. This configuration allows the tray to be inserted/retrieved within the external case and also allows compact disk to be engaged on the tray. However, this configuration is complicated and the smooth insertion/retrieval of the tray deteriorates when the elastic strength of the buffer spring is reduced. Also, when the front end of the tray is forcefully pulled, the spiked elastic piece could be damaged.

For the conventional compact insertion/retrieval cases, if the disk support tap which supports the punched hole at the center of compact disk is not formed according to the exact size, then compact disk could be damaged while forcefully being removed. This results in dislocation of compact disk and the loose movement within the case could cause some damage to the data stored in the compact disk.

Summary of the Invention

The present invention is designed to overcome the above problems of prior arts. The compact disc storage case comprises: a locking jaw which is formed at other face in opposition to one face of the square and is located at the lower section of said compact disc case; a lower case which comprises a pivot hooking jaw formed in opposition to the face where said locking jaw intersects; a upper case which comprises a slide guide perforated at the top and locked into a locking jaw formed in opposition to one and the other face of said lower case; a piece of dirt removing cloth attached at inside of an opening of said upper case for removing dirt during the time of insertion/retrieval; a locking groove which comprises a groove that locks into said pivot hooking jaw Hand formed on an inner face of said lower case ; a slide rail which protrudes from one face of said a locking groove; a slide lever which pushes a disk by sliding on said slide rail to enable the insertion/retrieval of the disk possible; teeth which are formed at the lower face of said slide lever in order to reduce the friction between said slide lever and said slide case; and a disk holding bar which is formed in parallel with said slide lever, supports one face of a compact disk and a disk insertion groove is formed in order to be able to slide. The present invention allows an easy insertion/retrieval of compact disk (CD) without inflicting damages to the surface of the compact disk where data is stored and also provides a convenient way for a long-term storage of compact disks where important data is stored. Also, the present invention has a simple configuration and while compact disk is being inserted/retrieved, the dirt removing cloth attached to the inside of the opening removes dirt on the surface of compact disk therefore providing a reliable compact disc storage case to users.

FIG. la is an exploded view of the compact disk storage case that illustrates the construction of the present invention in detail, and FIG. lb is an illustration of the inside of a slide lever. FIG. 2a is an illustration of an example of the usage of the compact disk storage case, FIG. 2b is a cross section view of the part A in FIG. 2a and FIG. 2c is a cross section view of the part B in FIG. 2a. These figures illustrate the opening of an insertion groove that was formed to accommodate an easy insertion/retrieval. FIG. 2 is a cross section view of a disk-holding bar that can store two compact disks. Prior to a detailed explanation of the present invention with reference to the preferred embodiments, a brief introduction of GPPS, which is conventionally used as a base material for manufacturing the compact disk storage case in the present invention, will be provided.

GPPS is transparent, strong and can be manufactured by injection molding process. It also is an excellent heat resistant material that has a wide variety of applications including TV, VTR, home electric appliances, OA equipment, insulator, medical equipment, etc. GPPS is also used for special purposes such as coloring products with a variety of different colors through the Computer Color Matching method, protection for light and electric discharges. As illustrated in FIG. 1, the lower case 10 is transparent and comprises an opening l(2a) which is formed at a lower level than a flange 12 at the opposite face in order to allow the insertion/retrieval of a compact disk through the one face of a square. The two opposing faces as illustrated in FIG. lb, a locking jaw 13, which is protrusion molded with a sharp cone shape at the top and a wide at the bottom so as to easily accommodate an insertion locking without being easily detached, is formed to be connected to an upper locking jaw 24a of an upper case 20.

A slide case 100 is fixed to a pivot locking groove 100 by sliding into an opening l(2a) formed at one face of the lower case 10 as well as a pivot hooking jaw formed by a protrusion from the flange 12 in the opposite face. Here, the pivot is a cone shaped spike where the top forms a sphere and the groove at the opposing face is also a semi-sphere hence they are able to lock securely. This locking can also be easily detached by applying a force at one face while lifting it upwards. This type of locking method is commonly used in compact disk storage cases. In the conventional compact disk storage cases, this locking is used for the upper cover while it is used for fixing the lower case 10 and the slide case 100.

As illustrated in FIG. 2b, in order to remove the interference between one face of the lower case 10 and the locking jaw 13 formed at the opposite face, an avoidance groove 111 is formed at one face of the slide case 100 and below a disk holding bar 140 at the other face. The avoidance groove 111 is not limited to certain area but it forms an elongated short protruding part rather than a groove in order to accommodate an easy metal molding during the manufacturing process. Likewise, the locking jaw 13 is put in underneath the elongated short protruding part. The avoidance groove 111 which is formed underneath the disk insertion groove 141, is formed thick in order to accommodate a short protruding part at one side. Also, at one upper face of the slide case 100, a slide lever 130, which has an identical groove to the shape of the squarely protruding slide rail 120, is constructed in order to slide the slide rail 120. The shape of the slide lever 130 as shown in FIG. lb and FIG. 2a is a "π " shape which is spread out at right angle from a vertex and a slide button 131 is inserted on the upper section of the vertex that allows a sliding movement of the slide lever 130 and by constructing a short protruding part 22 which allows an easy access through the short protruding part formed at the rear end of a slide lever guide 21. Also, in order for a freer movement during sliding, two teeth 134' are formed beneath a slider 134 as well as one tooth beneath a compact disk pusher 135. Internally, a compression spring 132 and a ball 133 are installed in order to slide on the slide rail 120 through the rotation of the ball 133. The slide button 131 is fixed by the elastic force of the compression spring 132 located inside of a button stay groove 23 which is formed at the rear end of the short protruding part of the slide lever guide 21 which is perforated at one face of the upper case 20.

Also, at the time of retrieving a compact disk, if the short protruding part formed at the upper section of the slide button 131 which is supported by the button stay groove 23 is matched with the short protruding part of the slide lever guide 21 by pushing the upper section of the slide button 131 through the short protruding part 22, then the compact disk is retrieved from the direction of an opening 2 without exerting any pressure on the slide button 131. As shown in FIG. 2a, if the perforated hole at the center of the compact disk is exposed to the outside of the upper case 20, then the compact disk is removed by holding the periphery of the compact disk and the hole at the center.

In this instance, a dirt removing cloth which is attached to the inside of the opening 2(2b) wipes out the dirt on the surface of compact disk as the disk is being inserted/retrieved by the movement of the slide lever 20.

Also as shown in FIG. 2a, the upper surface of slide button 131, uneven tooth are formed to prevent an accidental slip from the hands and a tunnel type even tooth are formed on the lower section of the perpendicular part in order to slide the upper section of the slide rail 120 by maintaining a specific amount of gap for the purpose of removing interference. Internally, a disk insertion groove 141 is formed to support one face of a compact disk and a compact disk pusher 135 in the shape a stick is formed in the horizontal direction around the vertex in order to support the lower section of the compact disk by inserting into the disk insertion groove 141.

Also, in parallel with the slide rail 120, the disk insertion groove 141 is formed on the disk holding bar 140 located at the other side. This is identical to the embodiment 2 and 3 as will be explained later. In general, the compact disk to be inserted to the compact disk case 1 forms an empty space from about 3mm to 5mm away from the outer periphery of the compact disk where no data is stored and this the section where the compact disc makes a contact with the disk insertion groove 141 during a insertion therefore preventing the compact disk from a possible damage. Unlike a light quality GPPS that was used for manufacturing parts such as the slide lever 130, the material for the disk insertion groove 141 can be a light quality silicon substance usually glued to the handle part of a toothbrush. For an easy insertion of a compact disk into the disk insertion groove 141, the width of the disk insertion groove 141 is wider at the opening side 2 and gets increasingly smaller toward the end face and no gap exists at the end point of the disk insertion groove 141 where the insertion of the compact disk finishes in order to securely hold the compact disk as shown in FIG. 2c. Also, it is preferable for the insertion groove of the compact disk pusher 135 which spreads out perpendicularly from the slide rail 120 to allow no gap in order to securely hold the compact disk. Finally, after the opening 2(2b) of the upper case 20 is identically matched with the opening l(2a) of the lower case 10 and also a upper locking jaw 24a, formed on an inner face of the upper flange 24 that moves downward at both ends, is matched with a locking jaw of the lower case 10, then the mutual locking jaws as shown in FIG. 2 are cross locked and the fixation of the upper case 20 is completed. The assembly of the slide lever guide 21 and slide lever 20 which are perforated at one side of the upper section is omitted since it is already explained with regard to the action of slide button 131.

As shown in FIG. 2d, the user can optionally choose a disk holding bar with two disk insertion grooves in order to store two disks at a time since the slide lever 130 and disk holding bar 140 can be removed or attached at will.

The replacement method of the slide lever 130 and disk holding bar 140 will be briefly explained as below. Since the disk holding bar 140 is being inserted under the small protruding part of the lower case and securely fixed due to the pressure stemming from the locking between the lower case 10 and upper case 20 as shown in FIG. 2b, if the one face of the flange 24, located at the lower section of both sides of the upper case 20, are spreaded apart, then the upper locking jaw 24a also spreads apart and being separated. Consequently, if the upper case is separated then the slide lever 130 and disk holding bar 140 constrained from the lower case 10 and upper case 20 become free. The user can now replace the part that can accommodate two disks. [Embodiment 2]

FIG. 3 and FIG. 4 illustrate a compact disk storage case according to the second embodiment of the present invention. FIG. 3 is an exploded view of the second embodiment. FIG. 4a is a perspective view that shows the usage. FIG. 4b is a cross section view that illustrates the opening of a hinged door by one end of a slide lever and the installation of a hinge door that keep the disk insertion/retrieval part closed using the tensile force of a spring.

The second embodiment as described in the first embodiment, the main body of the compact disk storage case comprises a upper case 20, a lower case 10 and a slide case 100 as shown in FIG. 3. In the upper case 20, a pivot spike (not shown) is formed on the out skirts of two downward flanges 24 and a pivot groove 220a is formed at one end of a hinge bracket 220 located at the both ends of the hinge door in order to be rotatable. Inside of the hinge door 200, a spring bracket is formed to hook up one end of the spring 230 and the other end of the spring 230 is hooked up to a hook 250 which is protruding from the upper flange 24 of the upper case 20 in order to maintain the closed state of the hinge door 200 using the tensile force of the spring 230.

Also, the slide lever 130a has a square type groove in order to slide over the slide rail 120 and a compact disk pusher 135 is formed at perpendicular to a vertex where the slide button is located. Inside of the slider 134 and compact disk pusher 135 that slides over the slide rail 120, one or two compact disk insertion grooves 141 are formed which is identical to the first embodiment. The differences in the second embodiment includes a longer slider 134, the part in the front end, which is in contact with the hinge door 200 and pushes the upper face of the hinge door 200, gradually widens from a narrow start and the sliding rail 120 which is formed at a lower section is made to slide on the upper section.

The reason for pushing the upper section of the hinge door 200 is to induce a smooth movement by pushing with an angle wider than the extended part of the spring 230.

Also, if the retrieval of the compact disk is completed, the hinge door 200 is automatically closed by the tensile force of the spring 230 caused by pushing the slide lever 130a toward the rear end and proceeding with the steps described earlier in a reverse manner.

As shown in FIG. 4b, in order to re-insert the compact disk, the disk is inserted to an insertion groove 141 formed on an inner face of the slider 134 and compact disk pusher 135 after exposing the slider 134 by pushing the slider lever 130 upwards, and if the slide button 131 is released at the slide stay home 23 after pushing the compact disk through a narrow groove of a short protruding part 22 by pressing the compact disk near the short protruding part by way of pulling the slide button 131 backwards, then the compact disk is pushed upwards due to the elastic force of the spring 132 therefore it can be securely stored for a long time without inflicting any damage to its surface.

The second embodiment as described in the first embodiment, the slide lever 130a and disk holding bar 140 can be replaced if required and the user can optionally choose a disk holding bar with two disk insertion grooves in order to store two disks.

[Embodiment 3]

FIG. 5 and FIG. 6 illustrate a modified embodiment of the compact disk storage case described in the second embodiment. Unlike the slide button whose direction is facing upwards in the second embodiment, the modified one faces towards the side wall in order to easily accommodate a storage of compact disk storage cases on top of another.

As shown in FIG. 5, All the configurations are identical to the first and second embodiments except the slide button 131a which is modified to face one face rather than facing upwards and unlike the second embodiment, FIG. 5 and FIG 6b show that the ball 133 is removed and a groove is formed so as to insert a part of the spring 132 into the face of the slide lever 130a to prevent the spring 132 from sliding out of its place, and the slide button 131a is mounted outside of the spring 132 in order for the perforated slide guide 21 is supported by the slide stay home at the rear end through the compression force from the spring as described in the second embodiment. As described in FIG. 6, the appearance of slide button 131a shows that the slide button 131a is supported by the lower section of the slide guide 21 with an additional short protruding part unlike the second embodiment.

Also, since the slide button 131a is only supported by the spring 132, the spring

132 can be broken away from the groove or interfere with the movement of the slide button when the upper section is pushed upwards during a retrieval of a compact disc. If a fixed stopping jaw 131b is formed at the front face and rear face of the slide button

131a, the previously mentioned problem can be prevented.

As shown in FIG. 6c, using the previously mentioned method, without the inconvenience of picking out every single compact disk storage case in order to retrieve a particular compact disk stored in a multiple number of compact disk storage cases, any compact disk can be retrieved for an inspection by pushing the slide button 131a upwards while a multiple number of compact disk storage cases are still in a overlapped state.

The changes and modifications of the fixing method of the slide button 131, 131a as described in the second and third embodiments can be apparent to those skilled in the art.

For instance, as shown in FIG. 7a, the slide button 131a is formed by a protrusion from one face of the slide lever 130a, and a semi-circular cross section at the lower end is synchronized to move together with the slide lever 130a that slides over the sliding rail 120 while maintaining a specific gap with the slide case, and in the fourth embodiment for the fixation of the slide lever 130a at a right position a stationary plate spring 136 which forms a circular arc with a specific height is used for fixing the slide lever 130a.

As shown in FIG. 7a and FIG. 7b, the stationary plate spring 136 is divided by a fixed end 136b which is locked together by a dish head bolt and nut and a free end which is freely movable. A circular-arc with a specific height is formed between the fixed end and free end and a stopper spike 137 is formed at one face of the free end 136a in order to prevent an interference between one end of the stationary plate spring 136 and slide lever 130a due to the rotation of one end of the stationary plate spring 136.

Furthermore, the lower circular part of the slide button 131a presses the fixed plate spring 136 while passing above it when the slide lever 130a is pushed toward the opening 2 in order to insert/retrieve a compact disk, therefore, the slide button 131a comes to be supported firmly allowing no rocking motion. And the fixed plate spring 136 is restored to its initial state due to its elastic force after the slide button 131a passes above the fixed plate spring 136. The base material for the stationary plate spring 136 is C520P of JIS H3130 which is commonly used for the positive terminal (+) of a battery case in general home electrical appliances and it is preferable to use a bronze plate spring. The reason for selecting the above material is that the recovery characteristic of the metal based on its elastic property from a deformed state due to an action of the slide button to a original state is excellent therefore able to prevent a permanent deformation of the spring due to a repeated forward/reverse movement.

Finally, the compact disk storage case according to the present invention allows an easy insertion/retrieval of compact disks while inflicting no damage on the surface of the disks and the problem of frequent break-downs of the hinged sections during the opening/closing of the cover of the conventional cases is resolved therefore providing an effective means for storing compact disks for a long time.

The present invention also provides a compact disk storage case with a simple, practical and economical construction and the case can either be stored in an individual or bookshelf style.
