Description

[Detailed Description of the Invention] This invention relates to an improvement in a so-called corner clip used when binding a plurality of pieces of document paper by gluing them together at a portion of a corner.

Conventionally, this type of clip has been popular, such as a type in which two clip members are pivotally connected to each other by a spring, or a type called a gem pin, etc.
In either case, multiple pieces of documents are simply glued together by the adhesive elasticity of the spring, so the clip itself or a part of the document can easily slip out due to a slight tensile force, making it difficult to securely hold the document. It is difficult and has a serious drawback that it is impossible to prevent misalignment and loss.

This idea was researched and developed to address the above-mentioned drawbacks, and when gluing multiple stacked documents, etc., the corners of the documents, etc. are folded together with the clip and enclosed within the clip. It is constructed so that it can be bonded in a fixed state, and maintains reliable adhesive strength without the risk of accidental movement and slipping out.
This corner clip has the feature of being easily reusable by being removably attached using the attraction force of a magnet, and the front adhesive piece is bendably attached to one side of the insertion piece. In addition, a back side adhesive piece is bendably connected to one side of the front side adhesive piece, and a magnetic adsorbent is attached to the insertion piece and the back side adhesive piece.

Next, the details of this invention will be explained based on the example diagrams.
Reference numeral 1 denotes a corner clip main body made of polypropylene and molded into a thin plate shape, which forms an insertion piece 2 in the form of a right-angled isosceles triangle, and is inserted into one equilateral side of the insertion piece 2 through a thin concave bent portion 3. The front adhesive piece 4, which is formed in the shape of a right isosceles triangle that is approximately the same shape and size as the piece 2, can be bent by positioning one of its equilateral sides so that the overall continuous shape resembles a right isosceles triangle. Further, on the oblique side of the front side adhesive piece 4, a back side adhesive piece 6 formed into a half-moon shape in this embodiment is attached via a thin and slightly wide concave bent part 5, and the right side thereof is In this embodiment, a magnetic adsorbent 7 such as a thin iron piece is adhesively attached to the back side of the insertion piece 2 of the corner clip main body 1, and a back side adhesive piece 6 A magnetic adsorbent 8 consisting of a permanent magnet having a strong magnetic force on the surface of
The corner clip is constructed by gluing and attaching.

In the above embodiment, the arrangement of the magnetic attracting bodies 7°8 can be freely selected, and the arrangement may be reversed. Instead of providing an iron piece on the other side, permanent magnets may be placed on both sides so that the positive and negative sides can be attracted to each other when used as a clip.

Furthermore, the material of the corner clip body and the shapes of the insertion piece 2, front side clamping piece 4, back side clamping piece 6, etc. can be freely selected as long as the desired bending operation and clipping function can be performed smoothly and reliably. For example, the shapes shown in FIGS. 8 to 10 may be used; however, the shapes shown in the embodiments may be
This is the most desirable from the point of view of function and aesthetics.

Next, to explain an example of the usage state based on the above embodiment, the insertion piece 2 of the clip is aligned and applied to the surface of the corner C of a piece of paper P such as a plurality of stacked documents, etc.
As shown in FIG. 4, fold the corner C of the paper strip P along the oblique side of the insertion piece toward you together with the clip, then fold the front side clamping piece 4 toward the corner side along the folded part 3, and then After inserting the corner between the insertion piece and the paper strip, fold the back side clamping piece 6 to the back side of the paper along the folded part 5, and the magnetic adsorbent 7 provided on the insertion piece 2 and the back side clamping piece By attracting the magnetic attracting member 8 provided at 6, the corner C of the folded piece of paper is strongly clamped between the insertion piece 2 and both the front and back adhesive pieces 4 and 6 in a state that it cannot be pulled out.

As mentioned above, according to this invention, unlike the conventional clip that simply clamps each piece of paper, the corner of each piece of paper can be inserted into the clip and held in a closed state. There is no risk of each piece of paper slipping out by accident, and it has the great advantage of significantly improving the function of the clip by reliably preventing the loss of the paper clips, and can be used repeatedly by attaching and detaching the attachment. In addition, there is no risk of damaging documents or other items enclosed in bags, etc., and it looks good during use without any discomfort, and is soft and pleasant to the touch compared to conventional products. It has a variety of unique features.
