  Since it is a device in which all the functions that cause the two states of arm inclination and inversion are stored at the base of the arm, it does not require a complicated structure called a frame, and only one bottom plate and the present invention, or Only with the present invention provided with a bottom plate, a book stand function in which an arm sandwiches and supports a book is realized. The simplicity of this structure naturally has the effect of low cost, application in use and design with functional beauty.

BEST MODE FOR CARRYING OUT THE INVENTION

  As shown in FIGS. 1 and 2, a rotary shaft 2 of a cylindrical body is formed on one side of the bottom end of the base portion of the strip-shaped arm 1, and the inner circumference is substantially C (sea) with respect to the rotary shaft. The necessary number of rotation shafts 2 of the arm 1 are passed through the cylindrical bearing 3 opened in a shape, and are arranged like a comb tooth, and the rotation shaft is within the opening of the bearing. The arm 1 can be bent at a necessary angle inwardly with a slight distance in the upper end direction from the rotation shaft 2, and the lower surface of the bent base portion is connected to the inner peripheral bottom of the C-shaped bearing 3. All the arms are aligned in this direction, and the upper surface of the bent arm 1 comes into contact with the upper end of the opening of the C-shaped bearing 3 to stop the rotation. Further, the upper end of the arm 1 is bent slightly inward. Since the upper end of the arm does not get caught or damaged when the book is pressed, the design is also excellent.

As shown in FIG. 3, the C-shaped bearing 3 is fixed to the rear edge of the bottom plate 4 on which the book is erected with a strong adhesive or the like. Furthermore, a plurality of C-shaped bearings 3 can be extended in accordance with the length of the bottom plate.

As shown in FIG. 3, the arm of the book stand device attached to the bottom plate 4 is rotated by its own weight until the bottom surface of the rotation shaft 2 comes into contact with the inner bottom surface of the C (sea) bearing 3, and this direction (forward). Tilt to and stop.
In this way, all arms are aligned and tilted.

As shown in FIG. 6, when a book is inserted from the front on the bottom plate, the arm pushed by the book is rotated backward and inverted, and the books on both sides of the book are sandwiched and supported while being tilted. When the book is removed, the arm 1 follows the book and restores its inclination by its own weight, and immediately prevents the books on both sides from falling down. All books do not fall down, and the arm 1 is not damaged by the pressure of the books falling down.

If the two arms 1 coming to both ends of the bearing out of the necessary number of arms contained in the C (sea) bearing 3 are fixed in an inclined state, the both ends of the stored class can be supported. Further, the shaft holes 5 of the arms at both ends serve as bearings for supporting both ends of the shaft.

As shown in FIG. 4, the outer shape of the C-shaped bearing 3 is formed as a rectangular bar-shaped bearing 3 </ b> A without an opening.

As shown in FIG. 5, when the square bar bearing 3A is installed on the bottom plate, as in the first embodiment, the back of the square bar bearing is fixed to the back of a place where a bookcase or other book can be placed. A comb-like book stand function is obtained.

As shown in FIG. 6, the rear end portion of the bottom plate 4 is bent to form a cylindrical C (sea) bearing 3. The required number of rotation shafts 2 of the arms 1 are passed through the bearings 3.

As shown in FIG. 7, a shaft hole 5 is formed at the center point of the rotation shaft of the arm 1, and the required number of the rotation shafts 2 is passed through the shaft rod 6. The arms coming to both ends of the shaft rod are fixed to the bottom plate 4 in an inclined state. When a book is placed on the bottom plate of the book stand, the arm 1 is inverted with the shaft rod 6 as a fulcrum. At that time, the protruding portion 2A is formed at that position of the rotating shaft 4, and the protruding portion comes into contact with the bottom plate 4 so that the rotating shaft 2 stops rotating. A projecting portion in that state is formed on the rotating shaft. If necessary, lift the arms at both ends slightly from the bottom plate and fix them to the bottom plate. This is to prevent contact with the bottom plate during rotation of the intermediate arm.

As shown in FIG. 8, the required number of rotating shafts 2 according to claim 4 are passed through the shaft rod 6, and the two rotating shafts at both ends of the shaft rod are fixed to the bottom plate at a necessary distance from the bottom plate 4. A notch 7 is provided at the bottom of the rotating shaft 2 according to the rotation angle from the inclination of the arm 1 to its inverted position, and the upper end of the L bar 8 placed horizontally on the bottom plate 4 is placed in the notch. The arm 1 is tilted and stopped by the contact between the front edge 7A and the L bar front edge 8A of the rotary shaft chopping, and is inverted and stopped by the contact between the chopping rear edge 7B and the L bar rear edge 8B.

As shown in FIG. 9, the front edge 7A of the cut 7 of the rotating shaft 4 of Example 5 is placed on a square bar 9 provided horizontally on the bottom and stopped at a predetermined inclination, and the rear edge 7B of the cut is formed. Inverts and stops when in contact with the rear side edge 9B of the square bar. In this case, the rear edge 7B must be longer than the front edge 7A for nicking.

If the C (sea) -shaped or square bar-shaped bearing or the two arms at both ends of the shaft bar 6 are fixed in an inclined state, the books at both ends of the stored books can be fastened there.

If the shaft hole and the shaft rod are made into screw holes and screw rods, this will allow the necessary spacing between the arms and the arms, and the arms and arms will clog and come into contact with each other over the course of use. Eliminate the possibility of loss of function. It is possible to determine the arm interval by inserting inclusions in a simple shaft rod and fixing them.

  The rotation shafts of the fourth embodiment, the fifth embodiment, and the sixth embodiment are not limited to the cylindrical body. If two states of inclination and inversion can be exhibited, for example, a rod-like body may be provided with a shaft hole and a notch.
