Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a card case device used for storing cards used in book catalogs and the like.

As is well known, cards used for library catalogs are stored in a card case device, but if the number of cards is small, the cards will fall over in the drawer of the card case device, making it difficult to organize them in an orderly manner. There were cases where the stored cards were out of order.

Therefore, in a conventional card case device, a locking piece is pivoted to the card holding plate via a spring so that the card holding plate can be fixed at any position within the drawer, and this locking piece is locked to the drawer. It has been considered that the cards can be stored in an organized manner by being stopped, and the card holding plate can be slid by rotating the locking piece against the spring.

However, when inspecting the card, the card holding plate of this card case device must be slid by rotating the locking piece against a spring, which makes it difficult to slide the card holding plate smoothly. It had its drawbacks.

In addition, in conventional card case devices, if the drawer part is pulled out halfway, the drawer part can be rotated upwards relative to the case body, which has the disadvantage that the cards stored in the drawer part are bent. It was hot.

The present invention was developed in view of the above points, and the card holding plate slides smoothly, and the drawer body cannot be rotated upwards when the drawer is halfway out of the drawer relative to the case body, thereby preventing the cards from being bent. The main features of this device are a locking piece with a rotation angle regulating mechanism attached to the top plate to prevent the drawer from coming off, and a drawer and case. an engaging member that engages with each other to prevent the drawer from rotating upward during the drawer; a card holding plate that is slidably and non-removably mounted in the drawer; and the card holding plate. a locking rod that penetrates through the drawer body and is provided in such a way that it can be freely inserted into and removed from the drawer body, a pressing spring that is inserted between the card holding plate and the front plate of the drawer body, and between the front plate and the rear plate. The card case device is characterized by comprising a removable card holding rod extending through the card.

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

Fig. 1 is an exploded front view and longitudinal sectional view of the card case device, and Fig. 2 is a transverse sectional view.
Figure 3 is a - line sectional view of Figure 2, Figure 4 is a cross-sectional view of Figure 2.
FIG. 5 is a partially cutaway perspective view of the drawer body, and FIG. 6 is a perspective view showing a locking piece with a rotation angle regulating mechanism. In Figures 1 to 6, 1
1 is a card case device, which is constructed by inserting a drawer body 3 into and out of a case body 2.

A locking piece 4 with a rotation angle regulating mechanism is attached to the front side of the top plate 21 of the case body 2 to prevent the drawer body 3 from coming off. A locking rail 5 is attached to prevent the drawer from rotating upward during the drawer. That is, as shown in FIG. 6, one piece 41 of the locking piece 4 with rotation angle regulating mechanism is attached to the top plate 21, and the other piece 4 is attached to the top plate 21.
2 is rotatably supported on one piece 41, and locking steps 43, 4 are provided at the pivot portion between both pieces 41 and 42.
4 is formed, and one piece 41 is connected to the other piece 42 as the sixth piece.
When rotated 90 degrees clockwise in the figure, both locking step portions 43 and 44 abut against each other, and further rotation is restricted.

Further, as shown in FIG. 5, the drawer body 3 has a middle bottom 31a made of aluminum material, for example, and also has a front plate 32 and a front plate 32 at both front and rear ends of a gutter-like part 31 having guide protrusions 31b protruding from inside both walls. The rear plate 33 is attached, and a groove 31c for preventing the card from falling out is formed in the inner bottom 31a of the gutter-shaped portion 31, and the stopping position of the card pressing plate 7 is adjusted in accordance with the number of cards 6 at the bottom of this groove 31c. It has a hole 31d for
A locking hole 31e with which the locking rail 5 engages is formed at the bottom of the gutter-like portion 31, and a locking hole 31e is formed in the bottom of the gutter-like portion 31, and
A cylinder 8 is fitted into the inside of the front plate 32, and a first protrusion 32a protrudes from the back surface of the front plate 32, into which one end of a pressing spring 9 is fitted. A projecting piece 82 is provided in the cylinder 8 so as to form a keyhole 81 in the center thereof.

Furthermore, the card holding plate 7, which is non-removably but slidably mounted in the drawer body 3, is inserted into the card holding part 71 into the groove 3, as shown in FIGS. 1 to 4.
A retaining portion 72 that is inserted into the card holding portion 71 and the retaining portion 72 are connected to each other.
A through hole 73 is drilled through the through hole 7.
3 is provided with a locking rod 10 that fits into the hole 31d. Further, a hole 74 is formed in the card holding portion 71, through which the card holding rod 11 installed between the front plate 32 and the rear plate 33 passes, and on both sides, the hole 74 engages with the guide protrusion 31b. A second protrusion 72 into which the other end of the pressing spring 9 is fitted is formed in the retaining portion 72.
A is provided protrudingly.

Furthermore, the card holding rod 11 has a locking member 1 at one end thereof which engages with and disengages from the protrusion 82 of the cylinder 8.
11 are screwed together.

In the figure, 12 is a handle portion of the drawer body 3, and 13 is a heading storage portion.

In the card case device 1 thus constructed, the drawer body 3 is inserted into the case body 2 while being prevented from coming off. That is, when inserting the drawer body 3 into the case body 2, use the rear plate 33 of the drawer body 3 to push the other piece 42 of the locking piece 4 with rotation angle regulating mechanism and rotate it counterclockwise. The plate 33 is inserted and mounted by passing through the rotation range of the other piece 42. Even if an attempt is made to pull out the drawer body 3, the locking step 43 of one piece 41 hits the locking step 44 of the other piece 42, and the other piece 42 does not expand more than 90 degrees with respect to the one piece 41. As the rear plate 33 hits, the drawer body 3 is prevented from coming off. Further, by inserting the drawer body 3 into the case body 2, the locking rail 5 attached to the bottom plate 22 of the case body 2 is inserted into the locking hole 3 of the drawer body 3.
1e, the drawer body 3 will not rotate upward during the drawer. Further, the card holding plate 7 is configured such that the card holding plate 71 is slidably placed on the inner bottom 31a of the gutter-shaped portion 31, and the retaining portion 72 is pressed by the pressing spring 9. Since the card holding plate 7 slides within the gutter-like portion 31 very smoothly, the card 6 can be easily inspected.

As explained in detail above, the card case device of the present invention has the drawer body slidably engaged with the case body by the engaging member, and the drawer body is engaged with the case body with the rotation angle regulating mechanism. This is provided with a stopper that prevents the drawer from turning upward when it is halfway out of the drawer relative to the case body, and also prevents the drawer from being pulled out. be.
