Abstract

PROBLEM TO BE SOLVED: To obtain a document retaining mechanism capable of always holding a document by a predetermined pressing force without influence of the quantity of the document by so constituting as to prevent the removal of an insertion plate by engaging the plate of a retaining plate with the insertion hole of a support base from above and coupling the engaging protruding stripes with each other. SOLUTION: In the case of using the document retaining mechanism, a document P is placed in front of a support base 1, and the insertion plate 5 of a retaining plate 4 is inserted into an insertion hole 2 from above. Then, the flat plate part 8 of the plate 4 presses the document P by the elastic force of a material to hold the document P to a board 9. At this time, since engaging protruding stripes 3, 7 are engaged with each other, the plate 4 is not pulled out upward. Since the stripes 3, 7 are formed of a plurality of stages, the plate 4 is pressed down in response to the thickness of the document P to make it possible to set it by the optimum pressing force, and the document P can be effectively held. Since the part 8 is set lower than the imaginary board surface L, even if the document P is little, sufficient pressing force is obtained.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to adjust the pressing force according to the amount (thickness) of a document to be bound, and at the same time, to easily attach and detach the document so that the document can be widely applied to various filing tools. It relates to a holding mechanism.

[0002]

Conventionally, as a means for temporarily holding a document, there are a clipboard in which a binding tool is provided on one edge of a flat plate, a clip file in which a cover is provided by folding in two, and the like. The document holding mechanism used for these is
Generally called a clip, a spring is wound around a long side of a steel wire rod bent in a substantially rectangular shape in a compressed state, and the restoring force of the spring presses the document on the other side. there were. Therefore, as the amount of documents to be bound increases, the spring pressure increases, making it difficult to attach and detach the documents. On the contrary, if the amount of documents is extremely small, the documents may drop out. Further, due to its structure, it takes a lot of labor and cost to manufacture.

On the other hand, when storing and carrying a document, various case files formed in a box shape are widely used, but in the conventional case files, a binding tool or a fixing tool as a document pressing mechanism is used. Since it was not equipped with, the documents were loose inside when carried, and the documents were scattered around, or the edges of the documents were damaged. Further, even if a binding tool or the like is equipped, most of them use a binding rod and cannot be bound without forming a binding hole in a document.

If a clip such as that used for the above-mentioned paper clip is applied to these case files, the side peripheral wall of the case becomes an obstacle, and it is difficult to lift and open the clip urged by the spring. Moreover, it is difficult to insert the document horizontally from the opened clip, which is not suitable for attaching and detaching the document.

Further, since the above-mentioned various kinds of binding tools are usually fixedly attached to either one of the upper side portion or the left side portion of the board, let's hold the already bound document with a paper clip, fastener, stapler, or the like. Then, the binding tool interferes with the stapler and the like at the binding position, which is inconvenient.

In view of the above situation, the present invention is to provide a new document pressing mechanism as a document pressing mechanism for a binding device, which can always hold a document with a constant pressing force regardless of the amount of documents. At the same time, the purpose is to make it easy to attach and detach documents and change the holding position.

SUMMARY OF THE INVENTION According to the present invention, a document pressing mechanism is composed of a supporting base and a pressing plate, and an insertion hole having a plurality of engaging projections on the inner side surface is provided on the upper surface of the supporting base.
The holding plate has a sandwiching plate having a flat plate portion at the tip thereof extending from the upper end of an insertion plate having a plurality of stages of engagement ridges that engage with the engagement ridges on the side surface. The above-mentioned problems are solved by making it possible to insert into the insertion hole.

Further, the above problem is solved by using a means for setting the flat plate portion at the tip of the holding plate to be lower than the virtual substrate surface in a state where the insertion plate is inserted to the lowermost stage of the insertion hole. .

In the document pressing mechanism of the present invention having the above-mentioned structure, the flat plate portion at the tip of the holding plate presses the document only by inserting the insertion plate of the pressing plate into the insertion hole of the support base from above. At this time, the engaging projections are engaged with each other to prevent the insertion plate from coming off, and by adjusting the insertion depth of the insertion plate, an appropriate pressing force is applied according to the thickness of the document to be nipped. It can be set. Further, by setting the flat plate portion to be lower than the virtual substrate surface, it is possible to reliably obtain the pressing force even if the document is extremely small.

BEST MODE FOR CARRYING OUT THE INVENTION An example of an embodiment of a document pressing mechanism of the present invention will be described below with reference to the drawings. FIG.
In FIG. 1, reference numeral 1 denotes a support base, which is used by fixing it to an appropriate substrate, and a plurality of horizontal projections are formed on one side surface inside the insertion hole 2 provided on the upper surface of the support base 1. The engaging protrusion 3 made of a strip is provided. On the other hand, reference numeral 4 denotes a document pressing plate, which has, for example, a sandwiching plate 6 having a substantially S-shaped side view and a notched central portion, which extends from the upper end of the inserting plate 5 which can be inserted into the insertion hole 2. The lower part of one side surface of the insertion plate 5 is provided with an engagement projection 7 formed of a plurality of horizontally extending projections that engage with the engagement projection 3 provided in the insertion hole 2. . The support base 1 and the pressing plate 4 are
Are integrally molded from synthetic resin materials.

Further, as shown in FIG. 2 (A), the flat plate portion 8 provided at the tip of the holding plate 6 is shown by a dashed line in a state where the insertion plate 5 is inserted to the lowermost stage of the insertion hole 2. It is set to be lower than the substrate surface (L). Usually, as described below, by adjusting the insertion depth of the insertion plate 5 according to the amount (thickness) of the document, the elasticity of the clamping plate 6 provides an appropriate pressing force for clamping the document. This is because even if the number of documents is small, such as 2-3, by inserting the insertion plate 5 to the lowermost stage, it is possible to obtain a sufficient pressing force for holding a small amount of documents.

Next, a method of using the document pressing mechanism having the above structure will be described with reference to FIG. When the document (P) is placed in front of the support base 1 and the insertion plate 5 of the pressing plate 4 is inserted into the insertion hole 2 from above, the flat plate portion 8 of the pressing plate 4 contacts the upper surface of the document and the elastic force of the material causes the document to move. Is pressed and the document (P) is clamped between the substrate 9 and the substrate 9 with an appropriate pressure.
In this case, since the respective engaging projections 3 and 7 are engaged with each other, the pressing plate 4 does not easily come out upward. Further, since the engaging ridges 3 and 7 are each composed of a plurality of ridges, the optimum pressing force can be set by pushing down the holding plate 4 to an appropriate position according to the thickness of the document to be bound, and the document can be reliably fed. It can be sandwiched. Further, since the flat plate portion 8 is set lower than the virtual substrate surface (L), it is possible to obtain a sufficient pressing force for holding the document even if the document amount is small.

On the other hand, by picking up the flat plate portion 8 of the holding plate 6,
It is possible to easily pull out a part or all of the document by creating a slight gap between the document and the document. Further, by pulling up the entire holding plate 4 upward to disengage the engagement protrusions 3 and 7 from each other, the entire document can be easily taken out.

In the above embodiment, each of the engaging protrusions 3 and 7 is composed of a plurality of stages of protrusions, but the present invention is not limited to this, and the pressing force generated by the insertion of the insertion plate 5 is not limited to this. It suffices that a locking force that prevents the insertion plate 5 from slipping upward due to a reaction can be obtained and that the insertion depth of the pressing plate 4 can be arbitrarily set. Further, the holding plate 4 is shown by extending the holding plate 6 having a substantially S-shape in a side view, which is cut out at the central portion, but the notched portion at the central portion is not always necessary.

Next, FIG. 3 shows an example in which the document holding mechanism of the present invention is applied to a paper clip, in which a supporting base 1'is fixed to one side edge of a flat plate 10 and a holding plate 4 is attached thereto. It has been fitted. In order to increase the gripping force, if a suitable ridge 11 or the like is provided on the lower surface of the flat plate portion 8 or on the flat plate 10 at a position facing the flat plate portion 8, the frictional resistance is increased at that portion. , It is possible to reliably prevent the careless removal of documents.

FIG. 4 shows the case where the document pressing mechanism is applied to a box-shaped case file. The support base 1 "is provided inside the box 12 at two positions, the upper side and the left side. The holding plate 4 can be selectively fitted.
As a result, even a document (P) bound in advance by a stapler or the like can be easily stored and held without the binding portion interfering. In this case, since the holding plate 4 is inserted into the supporting base 1 ″ from above and holds the document (P) as it is, the side peripheral wall does not become an obstacle as in the conventional case, and the document can be attached and detached very easily. is there.

The document pressing mechanism according to the present invention is not limited to the above-described embodiments, but can be widely applied to various filing tools for binding documents for temporary storage or convenient carrying. It is a thing.

[0018]

As described above, the present invention, as a document pressing mechanism for a binding tool, has a special effect that it can always hold a document with a constant pressing force regardless of the amount (thickness) of the document to be bound. Is to have. In addition, because it is easy to attach and detach documents and change the holding position, it can be widely applied to various filing tools, and since it can be integrally molded with an elastic material, it can be manufactured very easily and at low cost, and it has many advantages. is there.
