Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clip wheel for holding sheets of office documents. More specifically, it is referred to as a clip device (hereinafter referred to as the clip device in this specification) in which two clipping portions that hold paper products, etc. are connected by two arms that intersect at the rear. ), and provides such a clip device that is easy to handle and does not cause imbalance in the clamping due to crossing of both arms on either the front or back clamping side of the clip.

In clipping devices, the protrusion of the straw on the front and back sides of the paper leaf at the clipping part is small, and the protrusion from the edge of the paper leaf on the spine is small and balanced. Good adhesion to the surface of the paper sheet is strongly desired from the viewpoint of eliminating trouble during handling and from the viewpoint of attracting attention. moreover,
This is also important in that it stabilizes the attachment of the clip, prevents it from slipping out, and enhances the clamping function.

Furthermore, the clip device is used casually in S* of office processing, and there is a strong demand for it to be able to be handled quickly. Therefore, it is inconvenient to have restrictions on the front and back sides when using the product, and it is important that it can be used on either side when picked up. Furthermore, in general, it is unavoidable that this type of clip device undergoes some deformation when it clamps a thick object, so such a deformed device is used as a conventional paper clip, etc. If you can't use it upside down, it takes a lot of effort to restore the deformation. From this point of view, it is essential that it can be used in good condition on either side.

The nuclide clipping device is in its normal state (not holding paper sheets).
It is possible to obtain perfect planar symmetry in this case, but in use it is necessary to cross the arms at the back.

Up until now, it has been the easiest thing to do, and all that has been done is to cross the arms back and forth by the thickness of the wire at the back.

However, a slight imbalance in the front-rear direction at this intersection is highly desired on the outer end sides of both arms. For this reason, when the chestnut is pushed toward the edge of the paper sheet, the outer end of one arm protrudes backward, resulting in an irregularly held state.

In addition, the contact at the intersection of both arms affects the degree of opening of the pinching section in the pinching direction, impairing the equal pinching force on the left and right sides, and also reducing the amount of force from the pinching section from the surface of the paper sheet. Unbalanced lifting tends to occur.

The object of the present invention is to provide a paper sheet that is perfectly balanced and in close contact with the front and back surfaces and edge surfaces of the paper sheet, regardless of whether the paper sheet is held between the front and back sides of the paper sheet, thereby exhibiting a good appearance and a stable sandwiching function. It is an object of the present invention to provide such a clip device that is easy to handle.

The present invention provides both base relief means in which a portion of each arm from the portion corresponding to the center of the clip to the outside of the proximal end of the other arm protrudes rearward by an amount approximately equal to the thickness of the center line. At the same time, a crossed relief means is provided in which at least a portion of at least one side of the base relief means on the center side of the clip is bent and tilted in a direction away from the other arm part, and two The clip device is characterized in that the imbalance caused by the crossing of both arms is eliminated.

In the clip device of the present invention, its planar shape is completely symmetrical both in the normal state and when it is clamped. In addition, when in use, there is no front or back side, and the proximal and outer end sides of both arms are in close contact with the edge of the paper sheet, making it easy to handle. You can get the part you want.

Therefore, it can be handled carelessly in the same way as conventional gem clips and the like, and a much more useful amount of iron can be obtained.

Other objects, effects, and features of the present invention will become apparent in the following description of embodiments. Clip 1 shown in Figures 1 to 3 (1, one round wire rod vertically (front and back)
It is made by bending so as to have a completely symmetrical planar shape with respect to the center line
It consists of three main parts: a back part 121 consisting of both arms that intersect at the rear thereof; and a suppressing part 13 bent inwardly and forward of the outer ends of both arms. The back support is made up of a connecting portion 15 extending on both sides perpendicular to the center line χ of the portion 11a, and both straight helical shaft portions 16 of equal length bent rearward from both ends of the connecting portion 15 at right angles. It is a hollow plane in the shape of a . The rear ends 11 of both torsion shafts 16 are bent inward at right angles.

The end portions, that is, the outer end portions 19 form two arm portions 18 that extend beyond the rear end portion 17 of the opposite helical shaft portion to a position where they protrude outward by a certain length. Here, the rear end 17 corresponds to the base end of the arm.

The arms 18 intersect during the pinching process to form a spine 12 that contacts the edge surface of the sheet. The outer end portions 19a of both arm portions 18 are bent further forward and inward as shown in the figure to form suppressing portions 13 protruding from both sides of the torsional shaft portion 1@. Both inward pressing ends 22 are connected to the mating torsion shaft 1.
It is located near 6.

Neutralize both arms 18 of the cough clip 10.

Specifically, from the part that intersects with the center line A base relief means 30 is provided, which is formed to provide relief. Furthermore, as is clear in FIG.
is being done. In this way, by the base release means 30 having the cross release means 40, the base end side and the outer end side of both arms of the user 1 are arranged alternately in a line without contacting at the back in a normal state. can be located. FIG. 3 shows the state in which they are being held, and as is clear from the figure, both base release means are mutually dodging the base ends of the other arm, and the crossing release means 40 is intersecting the intersecting part of both arms. Acts to avoid contact with other people.

The backing part 11 is a side facing the back side 24 of the sheet 14, and the pressing part 13 presses the front side 23 with its pressing end 22 in a balanced manner. It can be seen that the proximal end and outer end sides of both sets 1s are in close contact with the edge surface 25 of the paper sheet. No matter which side of the backing part 11 the suppressing part 13 is opened to, no contact occurs at the intersection of the arms. At least there is no strong contact that would lead to the imbalance described above. For this reason, the clip device according to the present invention can be used on either the front or back side, and regardless of the thickness of the clip.
However, there is no imbalance in the sandwiched portion. We would like to remind the reader that in this type of clip device, which is made exclusively for clamping thick materials, the outer end of the base release means does not necessarily have to be connected to the base end of the mating arm, as in the case of the clip 10 shown in \. It is easy to understand that there is no need to go beyond and go outside.
That is, in this case, although the upper and lower ends of the supporting arms normally overlap, when a thick object is held, this overlap separates and the problem of imbalance in the holding does not occur. By doing so, the rearwardly projecting portion of the back portion 12 is narrowed, and the length of the surface in contact with the edge surface is increased, which is advantageous in terms of the stability of the clip.

The scope of the claims includes such embodiments as equivalents or easily modified forms.

4-5 show other embodiments of the invention. In the explanation of the clip 10 shown here, parts that are similar to those in the previous example will be indicated with the same reference numerals in the figure, and the explanation will be omitted as much as possible and the parts that are different will be mainly explained. .

#In the clip 1o, the intersecting relief means 40 are formed only at the intersecting portions of the inner sides of both base relief means 3o. That is, only the portions of the base relief means 3o that are close to the center line X are locally bent toward the side away from the other side, forming intersecting relief means 40'.

The clip 10 also has the same balance and function as the previous clip 1o both in its normal state and when it is clamped. Further, the clip 10' has the advantage that the protrusion in the thickness direction (front and back direction) is not noticeable when holding a thin object, and it is also advantageous in processing.

In addition to this, the crossing relief means may have a shape in which one side leaf of the two base relief means is bent and tilted so as to be separated from the other side. It has been found that this alone can sufficiently avoid contact at the intersection of both arms and prevent the occurrence of imbalance.

As described above, according to the present invention, the drawbacks of the nuclide clipping device can be solved, and it is possible to obtain the nuclide clipping device which can snip paper sheets of various thicknesses in a snug manner and is easier to handle.
