Description

  The present invention relates to a double clip for bundling and pinching paper sheets.

  As a clamping tool for bundling paper sheets, a metal plate having elasticity is bent into a substantially isosceles triangle shape in a side view to form a clip body, and an open / close lever bent with a metal wire is attached to the metal plate in a undulating manner. Double clips are well known. This double clip has a simple structure and is easy to use. On the other hand, since the open / close lever is made of a thin metal wire, there is a drawback in that when the knob operation is performed, the abdomen of the finger is locally pressed to cause pain.

  Therefore, as a means for eliminating this drawback, there are proposals disclosed in, for example, Patent Document 1 and Patent Document 2 in which a pressing plate is supplementarily attached to the knob portion of the opening / closing lever to distribute the force applied to the fingertip. .

  Among them, the proposal of Patent Document 1 provides a wire receiving concave groove on the inner surface of one or both of two thin plates whose base end portions are connected so as to be openable and closable, and is also inserted into the inner surface of one of the two thin plates. The protrusion is formed on the other side with a receiving hole for the insertion protrusion so that they can be fitted to each other.

  Further, the proposal of Patent Document 2 is provided with a groove portion to be fitted on the peripheral edge portion of the pressing plate, and the height of one groove edge of the groove portion is made lower than the other height, and the lower groove edge is raised. It is fitted so as to be between the knobs of the open / close lever in the posture.

  However, the double clip according to the proposal of Patent Document 1 has a design restriction because the connecting portion of the two thin plates must be protruded outward from the side edge of the main body, and the aesthetic appearance is impaired. In addition, the insertion protrusion and the corresponding receiving hole are formed straight in the height direction and the depth direction, respectively. On the other hand, the two thin plates having these have a connecting part. Therefore, when the knob portion is reduced in size, the curvature becomes large and the fitting cannot be performed.

  In addition, the double clip according to the proposal of Patent Document 2 has a high groove edge that is firmly hooked to the knob when applying force in the direction to hold the open / close lever, but the holding plate does not come off. When trying to reverse the lever to the prone posture, a force is applied to the lower groove edge, so that there is a drawback that the holding plate easily comes off.

  The present invention has been made in view of the problems of the conventional double clip, and an object of the present invention is to provide a double clip including a pressing plate that is easily and reliably assembled to an opening / closing lever and does not come off unintentionally. There is.

In order to achieve such an object, the double clip of the present invention
A thin plate having elasticity is folded into a substantially isosceles triangle shape when viewed from the side to form a back plate and a pair of opposing holding plates respectively extending from both longitudinal edges of the back plate. A clip main body provided with a bearing portion and a tip edge clamping portion, and a knob portion, an arm portion, and a rotating shaft portion that is bent outward in the width direction are formed by bending a metal wire into a substantially Ω shape. An opening / closing lever that is elastically expandable / contractible in the axial direction of the rotating shaft portion, and in a double clip in which the rotating shaft portion on the opening / closing lever side is inserted in a undulating manner into the bearing portion on the clip body side,
Consists of a core part and two flange parts extending radially outward from both edges of the peripheral wall of the peripheral wall, and is opened and closed by fitting a knob to a groove part between the two flange parts A holding plate attached to the lever is formed, and a stopper portion for retaining the holding plate is formed between the knob portion and the arm portion of the opening and closing lever,
In a state before the opening / closing lever is attached to the clip body, the stopper plate can be elastically expanded outward in the width direction, so that a holding plate can be inserted into the knob portion.
In a state where the opening / closing lever is attached to the clip body, the stopper portion cannot be expanded, and the pressing plate is configured not to come off from the knob portion.

  By adopting such a configuration, the holding plate housed in the knob part region of the open / close lever has a knob part and a stopper part surrounding the periphery, and two flanges that extend from the core part and sandwich the knob part therebetween Depending on the part, it cannot be moved in both the radial direction and the thickness direction, and even if a strong force is applied, it will not come off while being firmly attached.

  Note that the opening / closing lever and / or the pressing plate may be provided with a detent means for preventing the pressing plate in the attached state from rotating in the circumferential direction.

  By adopting such a configuration, there is an effect that it is possible to prevent the pressing plate assembled to the opening / closing lever from being twisted in the circumferential direction from the correct position.

  ADVANTAGE OF THE INVENTION According to this invention, the double clip which comprises the press plate which is assembled | attached to an opening-and-closing lever simply and reliably and cannot be removed carelessly can be provided.

  Hereinafter, although the embodiment of the double clip concerning the present invention is described based on a figure, it is not limited to this.

<< First Embodiment >>
1 to 4 show a first embodiment of a double clip according to the present invention, FIG. 1 (a) is a perspective view, and FIG. 4 (b) is a view seen from a position facing the surface of a pressing plate. FIG. 2 is a side view. FIG. 3 is an exploded perspective view. FIG. 4 is an explanatory view of the assembly process.

  In the figure, the double clip 10 includes a clip body 11 and a pair of opening / closing levers 15 and 15 and pressing plates 16 and 16, respectively.

  Of these, the clip main body 11 is made of a thin plate material excellent in elastic restoring force such as metal or synthetic resin, and a pair of plates extending from the back plate 12 and both end edges in the length direction thereof by bending the clip main body 11. Are formed in the shape of a substantially isosceles triangle in a side view. Further, both side portions in the width direction of the front end edges of the sandwiching plates 13 and 13 further extend in the forward direction (the direction opposite to the side on which the back plate 12 is disposed) and then outward (the direction in which they are separated from each other). It is rounded into a cylindrical shape to form tip edge sandwiching portions 13a and 13a. The leading edge holding portions 13a and 13a also serve as bearings for attaching the opening / closing lever 15 to the clip body 11 so that it can be raised and lowered. An insertion port 13b for insertion is provided. Similarly, the central portion of the front end edge of the holding plate 13 is also extended and then rounded outward (in the direction in which the front end portion is separated) into a substantially U shape, and the front end of the opening / closing lever 15 is placed inside the front end edge holding portion 13a. The guide part 13c for guiding to is formed.

  The structure of the clip body 11 is not different from that of the conventional double clip.

  Next, the opening / closing lever 15 is formed by bending a rigid and elastic metal wire, and a knob portion 15a that bulges in a substantially arc shape in the width direction, and extends from both ends of the knob portion 15a in the width direction. A pair of stopper portions 15b and 15b that are curved inwardly (in the direction in which they approach each other), further extending from the stopper portions 15b and 15b, and arm portions 15c and 15c that are gradually expanded outward in the width direction toward the tip; Rotating shaft portions 15d and 15d that are bent outwardly in the width direction from the distal ends of the arm portions 15c and 15c and extend respectively.

  The structure of the opening / closing lever 15 is different from that of the conventional double clip only in that a stopper plate 15b for retaining the holding plate is provided between the knob 15a and the arm 15c. is not.

  The pressing plate 16 is made of synthetic resin, and has a core portion 16a formed in a substantially short cylindrical shape and two substantially disk-shaped flange portions extending radially outward from both side edges of the peripheral wall. The two flange portions 16b and 16c and the peripheral wall of the core portion 16a form a groove portion 16d for inserting the knob portion.

  The double clip 10 according to the present embodiment having such a configuration is provided on the market by assembling the opening / closing lever 15 and the pressing plate 16 to the clip body 11 as follows. Hereinafter, the assembly process will be described with reference to the assembly process explanatory diagram shown in FIG. Here, the code is kept to the minimum necessary to avoid complication.

  First, as shown in FIG. 4A, the holding plate 16 is disposed between the left and right pivot shafts 15d and 15d of the opening / closing lever 15, and the left and right arm portions 15c of the opening / closing lever 16 are disposed in the groove 16d. It pushes in toward the knob | pick part 15a, making 15c fit.

  The arm portions 15c and 15c are closer to each other as the knob portion 15a is approached, and stopper portions 15b and 15b that are narrower than each other than the diameter of the core portion 16a of the pressing plate 16 are located in front of the knob portion 15a. Is formed. Therefore, the presser plate 16 is not blocked by the stoppers 15b and 15b and cannot pass through the presser plate 16, but the open / close lever 15 is made of a metal wire having an elastic force. As shown in FIG. 4B, the gap between the stopper portions 15b and 15b is expanded in the width direction due to elastic deformation, and the press plate 16 is allowed to enter the knob portion 15a.

  As shown in FIG. 4C, when the holding plate 16 is accommodated in the area of the knob 15a, the arms 15c and 15c of the opening / closing lever 15 are now picked up as shown in FIG. Then, they are compressed in the direction approaching each other, that is, inward in the width direction, and the distal end portion is brought into contact with the insertion port 13b of the distal end edge clamping portion 13a provided in the clip body 11. Thereafter, when the pressing force is loosened, the rotating shaft portions 15d and 15d are fitted into the tip edge holding portion 13a by the elastic restoring force, and are assembled to the clip body 11 as shown in FIG. 4 (e). Become.

  When the opening / closing lever 15 is assembled to the clip main body 11, the pressing plate 16 is surrounded by the knob portion 15a and the stopper portion 15b on the opening / closing lever 15 side in the radial direction, and the movement in the thickness direction is two. It is blocked by the flange portions 16b and 16c. Therefore, even when a large force is applied when the opening / closing lever 15 is reversed or when the pressing plate 16 is clamped, the attached state is maintained and does not come off.

  The presser plate 16 is integrally molded of synthetic resin here. However, the present invention is not limited to this. For example, the flange portions 16b and 16c are metal thin discs, and the core portion 16a is formed of synthetic resin. It may be combined. Moreover, the whole may be a metal thing and what combined the synthetic resin and the synthetic resin may be used.

  As described above, according to the present invention, the pressing plate can be easily and reliably attached to the knob portion of the opening / closing lever. In addition, by reversing the above procedure, the pressing plate can be easily removed without requiring force and without performing difficult operations, so prepare pressing plates of various colors and shapes. It is possible to increase the added value as a novelty product by replacing it as needed.

<Modification 1 of the first embodiment>
5 and 6 show a first modification of the first embodiment, in which FIG. 5A is a perspective view, FIG. 5B is an enlarged cross-sectional view of the main part, and FIG. 6 is a use state in which the open / close lever is in a prone posture. FIG. In addition, in order to prevent complexity, in the following description, the same code | symbol is attached | subjected to the thing of the same structure, description is abbreviate | omitted, and only a changed part is demonstrated. The same applies to other embodiments.

  In the first modification, the pressing plate 16 has a recess 16e formed at the center of one surface of the core portion 16a (the side closer to the clip body 11 when the open / close lever 15 is in the standing posture). By doing so, the core portion 16a and the flange portions 16b and 16c have a uniform thickness as shown in the enlarged cross-sectional view of the main part in FIG. There is an advantage that defects such as easy cavities and surface depressions can be prevented.

  It should be noted that a magnet having substantially the same shape as that of the recess 16e may be filled in the recess 16e. By doing so, it becomes possible to adsorb and fix the double clip 10 to a steel wall, a desk or the like, and the usability is further improved. Incidentally, in this case, since the recess 16e is closed by fitting a magnet, the recess 16e can be formed on the side of the surface that contacts the finger.

  Further, the opening / closing lever 15 here is provided with a bent portion 15e at the center portion of the arm portion 15c, and the rear half portion of the arm (side closer to the knob portion 15a) is raised to the clip body 11 side by the thickness of the flange portion 16b. It is approaching. As a result, as shown in FIG. 6, the pressing plate 16 is less bulky when the open / close lever 15 is in the prone posture with the paper sheet S interposed therebetween.

<< Second Embodiment >>
7A and 7B show a second embodiment, in which FIG. 7A is a perspective view, FIG. 7B is a diagram viewed from a position facing the surface of the pressing plate, and FIG. In the figure, reference numeral 20 denotes a double clip, 26 denotes a pressing plate, and 26b and 26c denote two upper and lower flange portions.

  Here, the fitting portion between the holding plate 26 and the knob portion 15a is only a total of three locations, that is, the vicinity of the opposing stopper portions 15b and 15b and the protruding end portion of the knob portion 15a.

  Thus, the knob portion 15a and the flange portions 26b and 26c of the pressing plate 26 do not need to be fitted over the whole, and in short, the fitting portion is disposed at an appropriate position so that the pressing plate 26 can be stably supported. If it was done.

  Further, as shown in FIG. 7C, the widths W <b> 1 and W <b> 2 of the flange portions 26 b and 26 c here are formed smaller than the diameter D of the metal wire constituting the opening / closing lever 15.

  Thus, even in the fitting portion, it is not necessary that the entire diameter of the knob portion 15a is completely fitted in the flange portions 26b and 26c. In short, the force that presses the holding plate 26 when the paper sheets are sandwiched. As long as each of the flange portions 26b and 26c has a length and thickness sufficient to withstand the force applied to the pressing plate 26 when the opening / closing lever 15 is reversed. It is desirable that the widths W1 and W2 of the flange portions 26b and 26c exceed the half (ie, radius) of the diameter D of the opening / closing lever 15. By doing so, even when a force is applied to the holding plate 26, there is no possibility that the knob portion 15a expands outward in the width direction due to the force, and the knob portion 15a receives and supports all the force. The effect that becomes possible.

  Here, the flange portions 26b and 26c have the same width and shape, and can be assembled without bending the front and back sides. However, the present invention is not limited to this, and each is different. Also good.

«Third embodiment»
8A and 8B show a third embodiment of the double clip according to the present invention, in which FIG. 8A is a perspective view and FIG. 8B is a view as seen from a position facing the surface of the pressing plate.

  In the figure, reference numeral 30 denotes a double clip, 36 denotes a pressing plate, 36a denotes a core portion, and 36b and 36c denote upper and lower flange portions, respectively.

  The flange portions 36b and 36c here are formed in a rectangular shape in plan view, and the core portion 36a is formed by projecting a detent projection 83 as a detent means from its peripheral wall in the radial direction.

  The anti-rotation portion 83 is provided so as to be positioned between the stopper portions 15b and 15b facing each other when the pressing plate 36 is incorporated in the knob portion 15a, and the pressing plate 36 rotates in the circumferential direction. This has the effect of preventing the inconvenience that the holding plate is twisted and the beauty is lost. Such a configuration is particularly effective when the shape of the pressing plate is a non-circular shape such as a rectangular shape in plan view as in this embodiment, but printing is performed on the surface of the pressing plate even if it is circular. It is effective in some cases.

<< Fourth Embodiment >>
FIG. 9 shows a fourth embodiment of the double clip according to the present invention, and is a view seen from a position facing the surface of the pressing plate. Reference numeral 40 denotes a double clip, 45 denotes an opening / closing lever, 45a denotes a knob, 46 denotes a pressing plate, 46a denotes a core portion, and 46b and 46c denote upper and lower flange portions, respectively.

  The flange portions 46b and 46c of the holding plate 46 here are formed in a heart shape in a plan view, and bend toward the inside of the knob portion area at the protruding end portion of the knob portion 45a as a detent means. An anti-rotation bent portion 84a is formed, and an anti-rotation concave portion 84b is formed inward in the radial direction at a position corresponding to the peripheral wall of the core portion 46a.

  As described above, the rotation preventing means may be provided on both the knob portion and the pressing plate, and may be effective by fitting them together.

  Further, as another detent means, for example, the elastic restoring force of the opening / closing lever is used, and when the opening / closing lever is assembled to the clip body, the peripheral wall of the pressing plate is strongly held by the stopper on the opening / closing lever side. It may also be one that plays a role of detent.

  As described above, the double clip according to the present invention is easy to use because the holding plate can be easily and reliably attached to the knob of the opening and closing lever, and the holding plate once attached is not inadvertently detached. It has the great advantage of being easy to handle.
