Abstract

(57) [Summary] [Purpose] A book stand that holds a book open. [Structure] Hold the top and bottom of the open page with wire 5 and wire 6,
A mechanism for fixing 5 and 6 by the lever 8 pressed to one side by the force of repulsion to close the book to be caught in the hole of the corner receiving member 3 and releasing 5 and 6 from the book by removing the catch. Book stand with.

Description

[Detailed description of the invention]

[0001] Conventional bookshelves are left unopened when the book is open, but there are some parts such as the work clamp that is pushed out from the bottom. It is difficult to keep it open for reading.

[0002] The present invention is intended to hold the open state by pressing near the upper and lower edges of the central portion while avoiding the character surface, and to release the state and easily turn the page, take out the page, and the like.

An example will be described. The bottom of both sides of 1 supports 2, 2 is on the short side of 2 and 10 is on both sides of the short side, and 4 is inserted at both ends, respectively. ing. As shown in FIG. 2, 9 is passed through the 4 holes on the upper left and the lower side, and it rotates in conjunction with 2 as the axis, and 5 and 6 rotate in the direction of pressing 11.

As shown in FIG. 3, 12 in 4 has 13 ends in the same 4 holes, and the other end is wound at a right angle of 12 so that 12 always rotates in the forward direction. As shown in FIG. 4, 8 which is screwed into the threaded portion of 12 is also pressed against the inside of the front edge of the elongated hole of 3.

When holding 5 or 6 and pressing 11, move 8 upward from the long hole of 3 and move to the direction where the outer diameter becomes narrower, and then press down there. When the force is released, the repulsive force of 11 pulls 8 downward from the hole, but this step is caught in the hole and locked, and 5 and 6 are fixed.

When 8 is pushed to the front and the step is removed from the hole, the lock is released and 5 and 6 are lifted from 11. Open 5 and 6, turn the page, and take it out.

The lock position is adjusted by turning the screw 8 according to the thickness of 11. Depending on the size of 11, loosen 7 and move 5 in and out to adjust the point of pressing.
