BEST MODE FOR CARRYING OUT THE INVENTION The bookstand of the present invention will be described below in more detail with reference to Examples. FIG. 1 is a perspective view showing a bookstand according to the first embodiment. FIG. 2 is a rear view showing the bookstand of this embodiment, and FIGS. 3 and 4 are AA sectional views and BB sectional views thereof.

The book stand of the present embodiment comprises a main body 1 for receiving the back side of books, a lower receiving portion 2 for receiving the lower part of the books, and an inclined support portion 5 for holding the inclined state of the main body. It is configured. The tilted support portion 5 of this embodiment is specifically realized by the leg portion 5 provided on the back surface 1b of the main body portion. Here, the leg portion 5 and the main body portion 1 are made of plastic or wood, and are preferably made of plastic for cost reduction and weight reduction. It is preferably made of wood.

In any case, the main body 1 has a substantially rectangular shape, and the lower receiving portion 2 is provided at the lower end of the front surface 1a.
A pair of protrusions 6 and 6 is formed in the center of the back surface 1b. As shown in FIG. 1C, a recessed hole 6a and a communication groove 6b extending downward from the recessed hole 6a are formed on the facing surfaces of the protruding portions 6 and 6. The width of the communication groove 6b is formed slightly smaller than the diameter of the recessed hole 6a.

The leg portion 5 is a substantially rectangular elongated plate shape, and its left and right widths are formed to be substantially the same as the distance between the protruding portions 6 and 6. A substantially circular insertion portion 5a that projects outward in the width direction is formed at the upper end of the leg portion 5.
The diameter of the insertion portion 5a is set to be slightly smaller than that of the recessed hole 6a and slightly larger than the width of the communication groove 6b. Therefore, when the insertion portion 5a is pushed into the recessed hole 6a using the communication groove 6b, the leg portion 5 is rotatably held by the main body portion 1. Also,
The upper end of the leg portion 5 is obliquely cut to form a contact portion 5b with the main body portion 1 (FIG. 3).

The lower receiving portion 2 is composed of a fastener which is installed in the center of the lower end of the main body surface 1a in the width direction and a restraining portion 3 which is rotatably held by the fastener. As shown in FIG. 1 (d), the fastener includes a base portion 4 of a substantially rectangular metal plate, a holding portion 4a formed into a bent cylindrical shape, and a locking portion formed at the bending end of the holding portion 4a. 4c and. In addition,
The locking portion 4c is formed so as to project in the inner peripheral direction as shown in the drawing. Further, the fastener having such a configuration is screwed to the main body 1 using the screw insertion holes 7 formed at the four corners of the base portion 4.

Specifically, the restraining portion 3 is formed by bending a metal round bar into a rectangular shape. The long side 3a on one side of the rectangle is inserted into the holding portion 4a of the fastener, and the long side 3b on the other side holds the open state of the book. A protrusion P is formed on a part of the one long side 3a.

The holding part 4a and the locking part 4c of the fastener are firmly holding a metal round bar to the extent that the restraining part 3 is allowed to rotate. Therefore, it becomes possible to fix the suppressing portion 3 at a desired position. However, when the restraining portion 3 is rotated until the restraining portion 3 and the fastener are formed into an L shape as a whole, the protrusion P of the restraining portion 3 comes into contact with the locking portion 4c of the fastener. Further rotation is blocked. Note that FIG.
(A) illustrates this limit state.

As described above, the contact between the projection P and the locking portion 4c ensures that the restraining portion 3 is fixed at the limit position, so that even a thick book having a hard cover can be securely held. It can be held in the lower receiving portion 2. Further, since the holding part 4a and the locking part 4c of the fastener firmly hold the metal round bar to the extent that the restraining part 3 is allowed to rotate, even a thick book can have any page. It is possible to fix with the open state. Further, since the lower receiving portion 2 is substantially composed of one round bar, when the book stand is stored, the projecting portion 3 is completely folded to minimize the protrusion. be able to.
