DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper clip for binding a sheet provided with a binding hole such as a loose leaf.

[0002]

2. Description of the Related Art In recent years, a binder type that can freely remove a paper provided with a plurality of binding holes, such as loose leaves, from students' notes has become mainstream. This is because, when lending and borrowing between friends or submitting a report to a teacher, it is easy to remove necessary pages and hand them over. At this time, the several sheets removed from the binder are often sandwiched and bound by a paper sandwich, and are often passed or returned as they are. Also, when carrying several sheets of paper before use, a paper clip is used. Conventionally, a paper pinch that sandwiches a sheet provided with a binding hole such as a loose leaf has a holding section that is urged by an urging member at one end side of a first holding plate and a second holding plate to sandwich the sheet. Has an operation unit for opening the holding unit side on the other end side,
A protrusion is provided between the holding portion on the first holding plate side and a connecting portion that supports the two holding plates, and a hole through which the protrusion passes is provided on the second holding plate side. There has been proposed an apparatus in which a holding portion of a plate sandwiches a sheet, and at the same time, a projection is inserted into a binding hole of the sheet so that the sheet does not fall off.

[0003]

However, in the above-described conventional paper sandwiching method, if the paper is used for general paper without binding holes such as copy paper or report paper, the projections hinder the paper from being sandwiched well. Not only is it impossible, but even if it can be sandwiched, it cannot be firmly sandwiched and it is easy to slip out. In addition, when used for paper provided with a binding hole such as an original loose leaf, the paper is sandwiched between the clamping portion of one clamping plate and the clamping portion of the other clamping plate, with the ends being the clamping portions. Therefore, when the paper pinch is lifted in a horizontal state, fluttering such as lifting of the edge side of the inserted paper with the both pinching portions as a fulcrum is likely to occur.

[0004] The present invention has been made in view of the above-mentioned conventional circumstances, and the object thereof is, of course, to be able to firmly sandwich a sheet provided with a binding hole such as a loose leaf without falling off. Another object of the present invention is to provide a paper pinch that can be used also as a general sheet without a binding hole and that causes little flapping of the sheet in the pinched state.

[0005]

According to a first aspect of the present invention, there is provided a holding means for holding a sheet at one end of a first holding plate and a second holding plate. In addition, in a paper clip having an operation unit for opening the clamping unit side on the other end side, a projection that can be inserted into a binding hole of a sheet is provided on the clamping unit side of the first clamping plate, The gist of the present invention is that an engagement portion is provided on the holding portion side of the two holding plates so that the projection portion engages in a free-running manner, and that the projection portion is configured to be able to turn upside down. In addition, the term “turning freely rotatable” means, for example, a state in which a shaft is formed at the base of the protrusion, and the protrusion is turned around the shaft as an axis. Claim 2 is a paper pinch having a holding portion for holding a sheet at one end of the first holding plate and the second holding plate, and having an operation portion for opening the holding portion at the other end. The gist of the invention is to provide a projection that can be inserted into a binding hole of a sheet on the holding portion side of the first holding plate, and that a recess is formed on the holding portion side of the second holding plate facing the projection.
The gist of the present invention is that the holding portion side of one of the holding plates is formed longer than the holding portion side of the other holding plate. The gist of the present invention is that a plurality of paper sandwiching main bodies are provided on one or both side surfaces of the two holding plates with connecting means which are detachably connected to each other. still,
The engagement means includes, for example, a dovetail formed on one side surface and a dovetail groove formed on the other side surface, or a convex portion formed on one side surface and a concave portion formed on the other side surface.

According to the above technical means, the paper clip of the present invention has the following effects. (Claim 1) When used for paper provided with a binding hole, the projection is raised, the projection is inserted into the binding hole of the paper, the paper is sandwiched, and the engagement portion is engaged with the projection in a free-running manner. In this case, the paper can be prevented from falling off, and when used for general paper without a binding hole, when the protrusion is turned upside down, the protrusion and the holding portion of the first holding plate are planarly arranged. Therefore, the sheet can be pinched so that the protrusion does not interfere. (Claim 2) In the case of using a sheet provided with a binding hole, inserting a projection into the binding hole to pinch the sheet so that the sheet does not fall out of the sheet pinch and to pinch a sheet without a binding hole. Then, the sheet is held between the holding portions of both holding plates, and the end of the sheet is released between the projection of the first holding plate and the recess of the second holding plate. (Claim 3) When the holding plate having the longer holding portion is used with the holding plate facing down, when the paper sandwich is lifted in a horizontal state, the edges of the inserted paper are held by the holding portions. Since the lower holding plate receives and supports the sheet from below in front of the holding portion in order to prevent the sheet from floating upward at the fulcrum, flapping of the sheet around the holding portion is prevented. (Claim 4) A plurality of paper sandwiching main bodies can be connected by a connecting means such as a dovetail groove or the like provided on one or both side surfaces of both holding plates.
