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

2 is a perspective view showing a retractable bookstore according to the present invention. 2, the present invention comprises a stationary bookcase 10 and a movable bookcase 20 provided on one side of the stationary bookcase 10, and both the stationary bookcase 10 and the movable bookcase 20 A shelf in which a book is placed such as a normal multi-layer structure book shelf, a top plate and a bottom plate provided respectively above and below the shelf, and a back plate is selectively provided.

In the present invention, however, a side plate a is provided at a longitudinal end of a horizontal plate portion (hereinafter, referred to as a horizontal plate) composed of the upper plate, the bottom plate and the shelf, So that the storage space can be adjusted according to the amount of the storage space.

The stationary book shelf 10 is configured to accommodate the movable book shelf 20 in addition to its function as a book shelf. To this end, the stationary book shelf 10 is provided with a cutout 13 at one end in the longitudinal direction of the first horizontal plate 11, And one end in the longitudinal direction of the second horizontal board 21 which is a horizontal board of the movable book rack 20 is inserted into the cutout portion 13 so that the storage space on the shelf can be adjusted do.

The movable book shelf 20 is provided on the front and rear sides of the bottom plate 23 provided on the bottom plate and the front and rear sides of the second horizontal plate 21 to allow the second horizontal plate 21 to enter and exit the cut- A front roller 25 and a rear roller 27 are further included.

The bottom wheel 23 is provided on the bottom plate on the side opposite to the entrance side in terms of the nature of the entrance and exit of the second horizontal plate 21 into and out of the cutout section 13. As the size of the movable book shelf 20 increases, When the movable book shelf 20 protrudes from the stationary book shelf 10 in order to increase the load on the exit side of the second horizontal plate 21, .

3 is a front view showing an auxiliary support plate of a retractable book shelf according to the present invention. 2 and 3, the auxiliary support plate 24 is inserted into the receiving groove (not shown) on the inlet-side bottom plate so that the auxiliary plate 24 is not interfered with the cutout 13 when the cut- b to be accommodated in the receiving groove b so that the receiving groove b can be projected and retracted through the hinge member 25a '' 'or the like so that when the receiving groove b is exposed from the cutout 13, Thereby supporting the entrance side.

In this case, since the auxiliary support plate 24 may be unstable due to the rotation due to the hinge member 25a ''', the auxiliary support plate 24 may be provided on the outer side of the spring seating groove 24a and the hinge member, A U-shaped spring 24b inserted into the spring seating groove 24a when the support plate 24 rotates and protrudes is further provided, thereby preventing the above-described support instability.

The front roller 25 and the rear roller 27 are disposed inside the cutout 13 in a state where the front and back rollers 25 and 27 are provided at the entrance and exit sides of the second horizontal plate 21. In this case, The protruding end 14 is formed on one side of the movable book shelf 20 so that the movable shelf 20 is prevented from being detached from the fixed book shelf 10 by allowing the protruding end 14 to be engaged with the roller.
That is, a protruding end 14 is formed at one side of the opening 19 of the cutout 13 to prevent the front roller 25 from being separated from the fixed bookhelf 10, And the rear roller 27 is opened to the other side so as to be detached from the stationary book 10.

However, the present invention can be provided in the inner corner or for the user's convenience, as shown in FIG. 4, the movable book shelf 20 and the stationary book shelf 10 can be bent and arranged at an arbitrary angle in a connected state .

2, the front roller 25 is provided in a state where the rotation guide bracket 25a is bent in the shape of a letter A. The end of the rotation guide bracket 25a is connected to the second horizontal plate 21 through a hinge member, As shown in Fig. When the rear roller 27 is made to be able to be detached from the incising section 13 by omitting the protruding end 14 at the longitudinal end e at the other side of the opening 19 of the incision section 13, (20) and the stationary book shelf (10) can be arranged in a bent state with each other.
Specifically, the rotation guide bracket 25a includes a first member 25a 'extending from one side of the front roller 25 toward the rear roller 27 and a second member 25b' extending from the end of the first member 25a ' A second member 25a '' bent toward the second horizontal plate 21 and connected to an end of the second member 25a '' to the second horizontal plate 21, The book shelf 20 is constituted by a hinge member 25a '''rotatably coupled with the end of the second member 25a''.

In this case, the front roller 25 supports the entrance / exit side of the movable book shelf 20 only when the auxiliary support plate 24 is not provided. Therefore, as shown in FIG. 5, in order to strengthen the strength and rigidity, The reinforcing ribs c are formed inside the bending points of the first member 25a 'and the second member 25a''of the rotation guide bracket 25a Is formed. Also, since a large load may be applied to the rotation axis of the wheel, it is preferable that the reinforcement horizontal plate (d) is further provided at the hub portion of the wheel for protecting the wheel.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
