FIELD OF THE INVENTION The present invention relates to storage of audio cassette tapes, and more particularly, to stackable cassette tape storage boxes.

The conventional stacked cassette tape storage box has a complicated shape consisting of at least four parts, which requires expensive equipment, resulting in higher cost of the product. Such a conventional tape storage box is a thin rectangular box suitable for storing a tape, and is opened and closed using elasticity of a spring around one corner thereof, and this storage box has a groove formed on a lower surface thereof. The protrusions protruding from the upper side of the other storage box are inserted into the storage box so that the storage boxes can be easily stacked.

However, in such a storage box, since the lower and upper surfaces of two adjacent storage boxes are arranged to be in contact with each other, it is difficult to fasten them together if the place where the storage box is not stabilized.

In other words, if the paired storage boxes are tilted or dropped, the stacked storage stacks are easily separated from each other.

In addition, each bin is a complex box model with drawers that fit directly into the bins with tapes built directly into them so that the top wall of one bin and the bottom wall of the other bin between the drawers and drawers in each bin when stacking the bins. Since the two walls are made to be located, not only the material is required but also the shape is complicated and the product is expensive.

In addition, in such a storage box, it is difficult to form a long groove in the lower surface of the storage box so that protrusions protruding from the upper surface of another storage box are difficult, and in order to form such a groove during the molding operation of the storage box, It requires long, narrow and relatively unstable fingers to work together, so the work must be precise as well as the mold itself, which leads to an increase in the manufacturing cost. Will not be precise.

Drawers in conventional storage boxes do not have the means to correctly hold the cassette in place, causing the cassette tape to rattling and swing up and down, which not only damages the tape itself, but also discomforts the user. The drawer, which is supported by a spring in it, is supported in the closed position by a spring latch formed on the outside of the drawer or a ball bearing in the groove, and is opened and closed by moving along the guide channel formed under the drawer. It is.

In addition, in the conventional tape storage box there is no means to fix the spring in the storage box or drawer, it takes a lot of time and money to install the spring, and if the drawer supported in the storage box is broken, the drawer is stored by the spring Since it is not fixed, the drawer is tipped out by the spring's restoring elasticity, which damages the tape.

In addition, means for interlocking the stacks and stacking the stacks are formed in the middle of the top and bottom of the stack, so that the effective area for attaching the label and the advertisement on the cross section divided into the front and the top and bottom of the drawer is extremely limited. do.

There was an improvement on the above-mentioned conventional storage box to form a track under the drawer to interact with the ball bearings installed under the storage box, which allows the spring to be fixed to the drawer for easy assembly and By changing the means of stacking, there was a space for maximum labeling.

However, these improved storage boxes also have irrational points, such as additional costs for installing ball bearings, complicated molds for use of hardened plastic materials, and no means for firmly supporting the cassette tapes in the drawers. When the track on which the ball bearing is seated is worn, there is a problem such that there is no means for preventing the drawer from being thrown out of the storage box by the elasticity of the spring holding the drawer.

On the other hand, the conventional storage box can not only be used in one case, but was not suitable in the case of a number of situations, in consideration of this point, the tape itself had to have a special structure according to the purpose of each case. In other words, the storage boxes that are interconnected and stacked are suitable for static environments such as homes, and the structure of several partitions is suitable for dynamic environments such as cars and boats. Although it is limited, of course, it is intended to be bonded to each other's purpose, but in general, since the tape storage box used at home can not be installed in a car or a boat, it is possible to take full advantage of this stacked feature and add portable storage. A new structure was required.

On the other hand, there was an automotive tape storage box in which the cassette tape of the car audio system was installed on the dashboard of the car, but this also had a complicated structure with several drawers and the tape was to be used elsewhere in the car. In this case, it is inconvenient to remove the tape from the drawer and move it to another storage box. Also, the automotive tape storage box acts as a thermal breaker and is detachably fixed to the dashboard. Problems such as becoming difficult are caused.

Accordingly, an object of the present invention is to provide a cassette tape storage box of a stacking type of stack which improves the problems described above.

The cassette tape storage box according to the present invention for achieving the above object has one base and two sidewalls extending upwardly from the base, a rear wall connected to the sidewall, parallel to the sidewall under the base A pair of extending first guides, a pair of second guides parallel to the first guides positioned inward to the top of the sidewalls, and a third guide that is coupled to the second guides to be detachably fixed to the storage box. On the other hand, it is provided with a lid which allows the second guide to bind with the first guide of the other storage box by separating from the storage box, and means for fastening the two storage boxes to be separated from each other.

The preferred embodiment of the means for fastening the two compartments to one another in such a manner as to be separable from each other is provided with an auxiliary snap fastening protrusion at the lower side of the base and the upper leading end of the rear, wherein the protrusion at the base portion is provided with a portion of the base. It is made of a resilient arm, and as the arm is bent, it is bound or separated from the auxiliary projection on the rear wall of the other storage box.

On the other hand, it is preferable that the arm does not bend when the drawer is closed and does not engage with the protrusion.

To separate the two lockers from each other, simply open the upper drawer and the locks will slide off.

Another preferred embodiment of the storage compartment is to form a guide channel on the upper side of the base adjacent to the sidewalls so that the storage compartment and the drawer slide together.

A preferred embodiment of the drawer is provided with a fastening arm which moves along a track formed in the base of the storage compartment when the drawer is closed and enters into the stop notch to fasten the drawer, the track of the base having a slope near the stop notch. And into the stop notch across the inclined portion of the fastening arm. On the other hand, the storage box is provided with an elastic means for pushing the drawer to the open position, the elastic means is a compression coil spring or a leaf spring or the like.

In another preferred form, when the drawer is opened, a number of blocks are formed on the back of the drawer so that the block stops on the base of the drawer in order to prevent it from being thrown out of the drawer by the spring's elasticity.

With the above structure, the base and the lid can be changed in various ways according to the situation, and even when the place of use of the tape can be used without changing the original storage box.

A preferred embodiment of the fastening means for fastening the drawer into the storage box may be a clasp mechanism provided on the front side of the drawer, which forms the storage box and the drawer in advance when forming the storage box.

As described above, the storage box is made by injection molding, preferably forming several wedges having an angle of 45 ° ± 10 ° so that these wedges form a guide channel and the wedge is a simple two mold used to make the storage box. Molding is possible.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a set of stacked cassette tape holders 11, wherein the tape holders 11 have one base 12 and two side walls 13 extending upwardly from the base 12 and the It consists of one back wall 14 connected to the side walls 13. The storage box 11 is provided with a plurality of drawers 15 to be opened and closed while sliding between an open position and a closed position, and a lid 16 that is detachable is attached to the upper side of the storage box 11 above the upper drawer. By removing the lid 16, the base 12 of another storage box is placed on one storage box 11, and several storage boxes can be stacked.

The base 12 portion is shown in detail in FIG. 2 and FIG. 3, and FIG. 2 shows the bottom of the base 12. The storage box 11 is injection molded using two divided molds. The bottom surface of the base 12 is formed with a plurality of protrusions 17 having an angle of about 45 ° ± 10 ° and spaced apart from each other, and the protrusions 17 are parallel to the sidewalls 13. ) To form the first guide. A pair of slides 19 are formed in the upper part of the side wall 13 and parallel to the channel 18 to form a second guide. The protrusions 17 and the slides 19 are integrally formed during the injection molding operation. It will be formed. The guide 20 formed on the upper surface of the base 12 is also formed during the injection molding operation, which is coupled with the slide 21 formed in the drawer 15, and the drawer slides in the storage box 11. To be installed.

One set of snap fastening protrusions 22 is provided on the bottom surface of the base 12 so that the base 12 is fastened to the upper end of the other cassette tape storage box, and the rear wall of the storage box 11 in the fastening protrusion 22. 14) Since the auxiliary protrusions 23 formed on the upper side are caught, these protrusions 22 and 23 form a means for fastening the two storage boxes to be separated from each other.

The fastening protrusion 22 is formed of an elastic arm constituting a part of the base 12, and the auxiliary protrusions 23 are formed as the channels 18 and the slides 19 formed in each storage box are relatively slid or bound. It is bent to bind or separate with. However, as will be described in detail later, when the drawer 15 is closed, the snap fastening protrusion 22 is not bent so as not to be separated from the auxiliary protrusion 23.

The front of the storage box (11) is provided with a protruding arm (24) surrounding both ends of the drawer (15), so that the drawer is securely and securely coupled when the drawer is fitted into the storage box (11).

A track 25 is formed in the center of the upper surface of the base 12, and the rigid and elastic fastening and guide arms 26 provided in the drawer 15 move along the track 25. The track 25 is for guiding the arm 26 when the drawer 15 is closed in the tape holder 11 so that the arm 26 enters the stop notch 27 to draw the drawer 15. To be locked in this closed position. On the other hand, a spring (not shown) is attached to the storage box 11 and the drawer 15 as an elastic means for holding the drawer toward the opening side, which spring serves to support the arm 26 in the stop notch 27. do.

In order to release the arm 26 in the locked state, the spring is compressed by applying a slight force to the outside of the drawer 15 and the arm 26 exits the stop notch 27 at the same time. The track 25 is given an angle which prevents the arm 26 from exiting through the same passage as when the arm 26 enters and guides the arm 26 toward the return passage 28. An inclination portion 29 is formed at the inlet of the return passage 28 near the stop notch 27 so that the arm 23 easily exits the notch 27 while the opposite end of the inclination portion is vertical. This prevents the arm 26 from returning to the stop notch 27 again. In other words, the track is such that once the force is applied to the drawer 15, the arm 26 is guided through only one passageway. Therefore, when the force applied to the front of the drawer 15 is released by the elasticity of the spring until the block 31 formed in the drawer 15 is caught by the stopper 30 formed in the base 15 ( By the action of pushing out of 11), the drawer 15 receives the elasticity of the spring so that it is no longer pushed out. A spring holding the drawer 15 outward is installed in a housing 32 which is formed in the inner central portion of the base 12, and the notch 27 when the arm 26 enters along the track 25. To prevent the phenomenon of entering into the return passage 28 without entering, the inclined portion is formed adjacent to the return passage 28 so that when the drawer 15 is closed, the arm 26 must be inclined to the track 25. It is only to enter the side.

4 and 5 and 6 show the drawer 15. FIG. 4 shows the upper side of the drawer 15, with a guide arm 26 in the center and one side of the spring in the center of the rear wall. A housing 33 is formed to cover the front end to form a mechanism that prevents the drawer from escaping from the storage box 11.

A slide 21 to which the guide 20 of the base 12 is fitted is formed near both side ends, and a stopper 30 to prevent the drawer 15 from escaping from the storage box 11 at one inner corner thereof. And a block 31 which interacts with the center, and the inclined hemispherical member 34 into which the spindle of the cassette is fitted at the centers of the left and right sides bisected by the center line is easy to attach and detach the cassette. . The rear side of the drawer 15 is provided with a flange 35 and an elastic pin 36 to hold the upper surface of the cassette to prevent up and down swings, while the elastic pin 36 prevents the cassette from mixing in the storage box.

FIG. 5 shows the back side of the drawer while FIG. 6 shows the side cross section of the drawer so that the front face 37 of the drawer 15 is suitable for attaching the label.

7 and 8 show the lid 16 of the tape storage box 11, the back of the lid 16 is shown in FIG. 7 to form a third guide along both ends of the lid 16. The guide channel 38 is formed so that the lid 16 can be detachably fixed to the storage box while being engaged with the slide 19 of the storage box 11 constituting the second guide. The guide channel 38 is formed in the tape holder 11 together with one wall formed by the projections 39 which are inclined at about 45 degrees with respect to the bottom of the channel 38 and formed at regular intervals. It has a cross-sectional shape similar to that of the channel 18, and a plurality of grooves 40 are formed at the rear side of the lid 16 so that the auxiliary protrusions 23 on the rear wall of the storage box 11 can be caught therein. The lid 16 is detachably fixed to the storage box (11).

In addition, a reinforcing web 41 is formed over the entire surface of the lid 16 to increase the bending strength of the lid and together with the guide channel 38 and the protrusion 39 and the groove 40 during injection molding. It is formed integrally.

8 shows a plan view of the lid and has a plane suitable for attaching a label label.

The storage box 11 according to the present invention having the structure as described above is assembled in the following manner.

First, the slide 21 of the drawer 15 is inserted into the guide 20 formed in the base 12 to join the base 12 and the drawer 15, and then the housing 32 and the drawer at the rear of the base. A spring (not shown) is inserted into the housing 33 on the rear side of the housing so that the drawer 15 is supported by the spring in the tape holder 11. The arm 26 of the drawer 15 fits into the track 25 and moves along it so that the arm 26 is positioned in the stop notch 27 when the drawer is closed and installed in the housings 32 and 33. Compressed spring is compressed. The lid 16 is coupled to the storage box 11 by inserting the slide 19 of the base 12 into the channel 38, and the auxiliary protrusion 23 of the storage box 11 in the groove 40 of the lid 16. ) Is fitted and detachably tightened.

In order to stack another storage box on one storage box 11, first, apply sufficient force to the lid 16 from which the lid 16 should be removed so that the auxiliary projection 23 can be released from the groove 40 and then slide. And 19 exits the guide channel 38. The slide 19 of one storage box is then slid to the channel 18 of the other storage box, with the snap binding protrusion 22 engaged with the auxiliary protrusion 23 so that both storage boxes are fully engaged. Slid in opposite directions.

Meanwhile, in order to separate the two storage boxes coupled to each other, the fastening protrusion 22 must be gently pushed up to separate the auxiliary protrusion 23. In this case, if the drawer 15 is closed, the fastening protrusion 22 is prevented from rising up because of the base of the drawer, thereby preventing the accident that the stacked storage boxes are accidentally separated.

In order to open the closed drawer 15, pressing the front of the drawer causes the spring 26 to be slightly compressed, releasing the arm 26 from the stop notch 27 and at the same time raising the top of the inclined portion 29. . The elasticity of the compressed spring then pushes the drawer outward so that the arm 26 follows the return passage 28 of the track 25 so that the drawer 15 does not escape out of the storage 11. While the stopper 30 and the block 31 are intended to interact, the spring is attached to both the storage 11 and the drawer 15.

The storage box according to the present invention as described above can be suitably adapted for carrying handles, suspenders, belts, or both cars and adhesives. It is a convenient cassette tape storage box that can be lifted and moved just as it is without the need for a storage box, or removal and re-carrying.
