Abstract

PURPOSE:To provide a page-opening retainer of simple structure, easy to handle effectively, which forms no disorder on the lower face of a book and retain the page opening state when it is moved. CONSTITUTION:An upper leg piece 2a of a clip 2 is fixed in the posture which can operate the opening and closing the leg from a bar shaft crossing direction on one end 1a of a protruding bar 1 hung between pages so that the purpose of opening page can be achieved rationally by protruding the leg from the side of a page having the larger page opening energizing force to the opposite page.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open page holder.

[0002]

2. Description of the Related Art When reading a book, a device which can be attached to the book to hold a desired page in an open state and maintain the state even when the book is moved is disclosed in Japanese Utility Model Publication No. 62-26221.
No. 5,34,952, and the like.
In the former, the clip parts facing each other on both sides of the base hold the both sides of the book, and in the latter, the U-shaped frame is sandwiched in the groove between the pages.

[0003]

In the former one of those described in the prior art, it is said that the both sides of the book are held by the clip portions brought out from both ends of the lower receiving frame for supporting the book, so that it is versatile for any page thickness. However, there is a problem in that the irregularity of the lower surface of the book becomes inconvenient when a force such as writing is applied to some page.

In the latter case, even if mechanically considered from the principle of leverage, it is necessary to exert the page-breaking blocking force at the most disadvantageous site, so it is important to secure the sandwiching pressure and the clamping surface. However, it is difficult to make it possible to deal with books of all page thicknesses, and further, there is a problem that the lower surface of the book is irregular as in the former case.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to cope with the page thickness regardless of the page thickness. An object of the present invention is to provide a page-opening holder that is free from irregularities and that can be attached and remarkably easily.

[0006]

In order to achieve the above object, the page-opening retainer according to the present invention has an upper leg piece of a clip at one end of a projecting support bar which is bridged between pages. The posture is fixed so that the legs can be operated from the direction orthogonal to the rod axis. The fixing of the clip to the end of the projecting rod body is preferably a pivotal stop that is rotatable on the opposite side. The projecting rod body may have an anti-slip shoe provided on the lower surface of the end opposite to the clip mounting end. Furthermore, in addition to this, it is preferable that the projecting rod body is curved in the arch midway.

[0007]

In general, the projecting support rod is bridged between page breaks, and the upper and lower leg pieces of the clip pinch a predetermined number of pages on the side where the page thickness is thin and the closing page biasing force is strong, causing slippage at all. Form a fulcrum of a unique fulcrum. On the other hand, the opposite end secures a supporting point of the fulcrum on the page on the side where the page thickness is thick and the closing force is weak or hardly generated.

[0008] Thus, an extremely stable protrusion is formed here as if the supporting leg was extended from the side on which the person is about to fall. It is convenient that the clip can be rotated to the opposite side of the clip rod axis when the clip is mounted on the side where the clip is mounted, and the mounting side can be accommodated and the side projection can be eliminated.

If the anti-slip shoe is covered at the supporting point of the above-mentioned upper support, the treading is surely performed and the supporting ability is enhanced. Furthermore, in addition to this, when the midway of the protruding rod is bent into an arch, the opposing force of the rod shaft against the page closing force is elastically increased, and a very suitable protrusion is formed. .

[0010]

EXAMPLES Examples will be described with reference to the drawings. Figure 1
At one end 1 of the projecting support rod body 1 spanned between pages
The upper leg piece 2a of the clip 2 is fixed to a in a posture such that the upper leg piece 2a of the clip 2 can be operated to open and close the leg in a direction orthogonal to the rod axis of the protruding rod body 1. It is preferable in terms of feel that the fixing is performed by engraving a step on the end 1a and then assembling the end to make the surface flush.

Reference numeral 3 in the drawing denotes a non-slip shoe which is preferably mounted on the lower surface of the end 1b opposite to the end 1a. In FIG. 2, a clip 2 is a fulcrum rod body 1 at a pivot point 4.
It is recommended to fix it to and to rotate it to the opposite side of the rod axis. As shown in FIG. 3, when the clip opening operation arm 5 can be swung, as shown in FIG. It can be stored in the shape of a stick that does not project to the side, which is convenient for carrying. Further, as shown in FIG. 2 above, since the clip 2 can be freely arranged on both sides of the rod shaft, as shown in FIG. 4, in the case of the right-turning book 6, with a closed page with a thin page thickness. Although the clip 2 is attached to the right page side where the power is large (a), when the page turning progresses and the left and right are reversed, the clip 2 must be transferred to the left page side. If the orientation is not possible, there is no choice but to mount it on the upper side of the open page (b), but this is very troublesome. However, if the orientation can be changed, it will be possible to attach it to the lower side as before (c),
It is suitable.

Depending on the attachment of the anti-slip shoe 3,
The fixing force at both ends for the page opening of this product is both firm,
Although the open page holding force becomes stronger, the projecting support bar body 1 must endure the closing page biasing force, and in the case of the straight plate body, it may be bent halfway as shown in FIG. 5a. Therefore, as shown in FIG. 6, it is advisable to reinforce the middle of the projecting rod 1 by arching it in the arch 7. Then, since the arch 7 resists in proportion to the bending biasing force, a repulsive force rich in elasticity is generated and the open page is surely held (FIG. 5b).

However, it is good that the page contact surface of the lower leg of the clip 2 is free from page damage by bending.

[0014]

Since the present invention is configured as described above, it has the following effects. (1) It is easy to do because the mounting part (clip holding part) does not have to be the entire page thickness with one touch, but only a part of the upper layer. (2) Since it is effective with a total length of only 110 mm, it is compact and convenient for storage and transportation. (3) The lower surface of the book is not irregular during page opening, and the book is not tilted due to writing or the like and is excellent in usability. (4) No complicated mechanism or strong rigidity is required, and the product can be manufactured at low cost. (5) One end of the protrusion is a clip 2 for holding a predetermined number of pages, and the other end is an upright position on the page in a substantially lying position, which does not damage the paper at all and is easy for books.
