The book shelf 100 of the present invention has a space for storing the book 50. The book shelf 100 has a space between the lower plate 102 and the upper plate 104, The two side plates 106 are vertically fixed. In general, the book 50 can be stored vertically standing, and the front side is opened so that the book 50 can be loaded into the inside of the bookcase 100. Although the figure shows that one lower plate 102 and the upper plate 104 are provided and two side plates 106 are provided on the left and right sides between the lower plate 102 and the upper plate 104, the space in which the book 50 can be inserted can be configured in multiple stages.

An insertion groove 102a is formed in the front surface of the lower plate 102. [ The insertion groove 102a extends to the center through the inside of the lower plate 102. [ A space is formed in the insertion groove 102a so that the rod button 108 can be moved in the front and rear direction and is open upward in the middle of the lower plate 102 to communicate with the space in which the book 50 is stored.

The rod button 108 moves forward and backward inside the insertion groove 102a and one end protrudes from the front of the lower plate 102. [ The user can push the bar button 108 protruding forwardly into the insertion groove 102a.

A toothed portion 108a is formed on the upper surface of the other end of the rod button 108. [ The toothed portion 108a is meshed with a toothed gear 112 which is formed with a serrated pitch in forward and backward directions and is rotatably fixed within the insertion groove 102a.

The toothed gear 112 is formed with teeth of a size and a shape coinciding with the toothed portion 108a on the surface. Accordingly, when the rod button 108 is moved, the toothed portion 108a moves horizontally to rotate the toothed gear 112 engaged with the toothed portion 108a.

A spring 110 is provided at the other end of the rod button 108. [ The spring 110 generates an elastic force to move the rod button 108 moving into the insertion groove 102a in the frontal direction of the bookcase 100. [ As a result, when the user presses and releases the bar button 108 by hand, the bar button 108 is moved by the spring 110 to return to the original position.

A sliding rod 114 is provided above the gear 112. On the underside of the sliding bar 114, a toothed portion 114a having the same size and shape as that formed on the surface of the toothed gear 112 is formed. As a result, as the toothed gear 112 rotates, the sliding plunger 114 horizontally moves forward or backward.

The lower end of the sliding bar 114 which is in contact with the toothed gear 112 is located inside the insertion groove 102a and the upper portion of the sliding bar 114 which is in contact with the back face of the book 50 is protruded outside the insertion groove 102a. Therefore, when the sliding stick 114 moves in the front direction, the book 50 which has been in contact with the sliding stick 114 moves toward the front direction and escapes to the outside of the bookcase 100.

That is, when the user pushes the bar button 108 while the book 50 is inserted into the bookcase 100, the bar button 108 slides in the backward direction. Then, the toothed gear 112 is rotated. And the toothed gear 112 slides the toothed sliding rod 114 upward in the front direction.

The toothed gear 112 is installed at a fixed position inside the lower plate 102, while the lower bar button 108 and the upper sliding pin 114 are installed to be movable back and forth. Therefore, when the rod button 108 is moved backward and the toothed gear 112 is rotated, the upper slide pin 114 moves forward as opposed to the rod button 108. [

As a result, the book 50 stored in the bookcase 100 comes out to the outside. It is preferable to store one book 50 in correspondence with one button so that the book 50 desired by the user can be moved forward. In some cases, multiple books 50 may be configured to be pulled out by one bar button 108.

When the user releases his / her hand from the bar button 108, the bar button 108 is slid in the front direction by the spring 110. As a result, the toothed gear 112 rotates in the opposite direction and the sliding rod 114 slides in the rear direction. The rod button 108 and the sliding plunger 114 return to their original positions.

FIG. 7 is a cross-sectional view showing the structure of the bar button and the rotating bar, and FIG. 8 is a sectional view showing the operation of pushing the book by pressing the bar button.

In the above-described embodiment, the rod button 108 rotates the toothed gear 112 and moves the upper slide pin 114. In this embodiment, the same operation is implemented using the rotating link arm 116 do.

The bar button 108 is slidably installed inside the insertion groove 102a as before. At the other end of the rod button 108, a spring 110 is installed in the same manner.

One end of the link arm 116 is rotatably mounted on the other end of the rod button 108 by a link rotation shaft 108b. And a rotary push rod 118 is installed above the rod button 108 so as to be slidable in the front-rear direction. One end and the other end of the link arm 116 are rotatably installed on the link rotation axis 108b of the bar button 108 and the link rotation axis 118a of the rotation stopper 118, respectively. The center of the link arm 116 is rotatably fixed at a predetermined position inside the insertion groove 102a.

As shown in Fig. 8, when the user presses one end of the bar button 108 by hand, the bar button 108 slides rearward. And the link arm 116 rotates about the central rotation axis as the rod button 108 moves. Once the link arm 116 fixed to the link rotational axis 108b of the rod button 108 rotates, the other end fixed to the link rotational axis 118a of the rotational push rod 118 is rotated in the opposite direction. As a result, the pivot 118 is moved in the front direction, pushing the book 50 out of the bookcase 100.
