Description

  The present invention relates to an office clip used to separate and bind documents, which improves the problem of handle pin protrusion, which is the biggest drawback of the folder clip commonly referred to as a conventional binding clip, to obtain a body and a handle member. This is a clip of a new structure in which the fastening method is changed from the pivot connection method to the insertion method.

  The general shape of the conventional business use binding clip is provided with a main body made in the shape of an isosceles triangle by bending, a pivot joint fastened with a handle pin is formed at the tip of the upper and lower main bodies, and paper It also serves as a role to push the

  The pivot joint formed at the front end of the body has a hinge formed on the left and right sides so that both ends of the bent pin are not inserted and separated, and the central part is not hooked when paper is inserted Rounding is applied to a shape similar to.

  However, in such a general clip structure, although the corners at both ends of the hinge are said to be processed into a round shape, since they are protruded, the paper is easily torn, and a plurality of document bindings are In the case of stacking, the problem of catching on the hinge often occurs.

  In addition, since the handle pin must play a role of lever, there is a problem that it is structurally protruded out and caught, and in order to alleviate the problem, it may be rotated downward and stored. If you view or spread the documents, they will get stuck on the pins and cause inconvenience. In other words, since the handle pin is larger than the body, there is a problem that the document is stuck on the pin every time the user shook the document after binding the document, and thus the document is not easily turned.

  Due to such inconvenience, in some cases, the handle pins are separately separated and stored, but there is a problem that it is very troublesome to rejoin when necessary, and it may be lost if mistaken there were.

  The conventional binding clip as described above is made of a simple structure to which the principle of leverage is applied, but the distance between the power point, the action point and the fulcrum is so long that the document is bound, Since the handle pin is unnecessarily protruded in the upper and lower directions, there are inconveniences in handling such as stacking and storing a large number of documents.

  The present invention has been invented to solve such problems, and in particular, by changing the structure in which the hinge is formed on the contact or compression portion of the paper at the end of the main body in the conventional method, The main object is to provide a binding clip with an improved structure that allows the shape and design of the abutment to be made more diverse.

In order to solve the above problems, the folder type binding clip of the present invention is
Elasticity is generated by symmetrical bending of an upper and lower isosceles triangle composed of one body, and thin and elongated elastic material is generated, and the lever principle is applied when pressing the holding handle pins fastened on both upper and lower sides A main body that operates while the upper and lower parts are opened and closed by
A guide groove which is cut by punching at the central portion of the upper and lower symmetry planes of the main body and is fastened to the handle pin via a pair of grooves formed in the shape of a sliding latch in parallel to the left and right;
A pair of handle pins inserted in parallel in the shape of 11 through the guide groove; and when binding a document, the handle pins are projected upward to improve the contact force of the finger and the role of the force point of the lever A binding clip characterized in that after the paper is placed in the clip, the handle pin is inserted downward into the guide groove for storage, or when the document is unfolded. As the main means for problem solution.

  The present invention provides a binding clip characterized in that the length of the handle pin is reduced to a degree similar to the length of the main body in order to solve the above-mentioned problems more effectively. The sliding latch, which acts as the point of action of the main body, is located at the upper end of the paper contact surface of the main body, so the distance from the bending portion of the main body, which plays the role of a fulcrum, is reduced Nevertheless, it is possible to provide a binding clip characterized in that the same elastic force as a conventional binding clip makes it possible to easily release the compression part with a smaller force.

  Using the folder-type binding clip of the present invention, the size of the pressing handle pin can be greatly reduced, and the problem of catching when viewing or storing the document can be solved, and the hinge of the conventional clip can By removing from the contact portion, it is possible to reduce the problem that the paper strikes the hinge end of the conventional folder clip and wrinkles or breaks.

  As described above, in the conventional binding clip, the hinge which can be said to be the fastening portion of the main body and the handle member is formed in the pressure contact portion, and the distance between the action point and the fulcrum is long according to the principle of leverage. The binding clip of the present invention has a shorter handle pin length than the conventional method, and in particular, is inserted inside when not in use, while the distance between the handle pin and the handle pin where the The convenience of use and storage is increased.

  In addition, since the number of manufacturing processes is hardly increased or added as compared with the conventional binding clip, there is no factor that increases the manufacturing cost, which is economical.

  In addition, when the present invention is applied, the hinge structure of the portion in contact with the paper disappears, so that the shape of the contact portion can be processed into various shapes such as circle, oval, triangle, square, heart shape, and wave shape. Can be expected to have an effect of increasing the commercial value rather than the design side.

  In the present invention, the handle member can be made using a plate-like material as well as the conventional common metal pin, and the user's preference can be satisfied in terms of design and convenience.

The first means for achieving the above object is a clip main body made of an elastic elongated metal plate, and two or more in a symmetrical manner with respect to the central portion 13 of the metal plate material of a fixed length. to form a bent portion 12, after the pressing surface 14 between bent to the shape of an isosceles triangle when viewed from the side is bent so as to contact, it causes these ends of the tip 15 elastically contact between these if Hasamikome paper is configured oppressive abutment 15 which can be fixed by the elastic pressure, insertion handle member (20 or 40) between these central bent portion 12 and the compression abutment 15 is, includes a fastening portion 30 made by incision and bending to allow horizontal movement, two separate the handle member for extending the compression abutment (20 or 40) is fastened portion Protrusions and insertions can be made by inserting in 30 and moving up and down It is characterized by being made.

Second means, as the elastic bent portions are symmetrically formed at opposite ends from the body middle part, or the two are formed in order to increase the elastic force of the compression abutment 15 of the terminal, the symmetric distance between the resilient bent portion is maintained by a width corresponding to maximum insertion thickness of the paper, the α inner contact angle of both end portions appropriately change the internal angle of the resilient bent portion 12 so as to be within 90 ° In order to maintain elastic strength more effectively, additional bends can be formed between both elastic bends. At this time, the position of the fulcrum with which the handle member 20 is brought up and brought into contact by lifting the fastening portion according to the lever principle is formed in the outer surface of the elastic bending portion or in the cut groove on the bending portion.

The third means is made by bending a rigid pin or plate separated from the main body as a handle member, and the sliding groove of the fastening portion 30 formed by cutting and bending on the pressing surfaces 14 on both sides of the main body or by being attached to the sliding latch, the user presses the manual operation by can be repeated easily inserted protrusion or pulling, at the time of projecting Ru is designed to be the role of lever to lift the fastening portion by the pressure of a finger.

The fourth means is a handle member of an appropriate size and shape that meets the object of the present invention, and the sliding operation lowers the lower end 22 of the handle member to the compression abutment portion 15 of the main body at the time of insertion. The length between the lower end of the handle member and the upper end 21 is less than the length between the end of the compression abutment 15 of the main body and the upper end 12 of the bending portion so that it does not protrude much outside the bending elastic portion of the main body it is desirable that no more than 30%, or lower end 22 of the handle member is bent tip of the pin so as not to easily detached caught the lower end 33 of the fastening portion, is caught by a step in the fastening portion formed when projecting the handle member It is characterized by being.

Fifth means, in order to achieve the above object, the fastening portion 30 which is formed at the center top end of each side of the pressure surface 14, above the intermediate position between the contact portion and the resilient bent portion, i.e. is installed in place of the near have positioned elastic bent portion, by arranging in parallel with 11 shaped on the right and left sides of the center point as a reference, so that the handle member is movable in place on the top and bottom along the bore of the groove or cylindrical It is processed into the form of sliding grooves or sliding latch on. At this time, the bending direction of the sliding groove or latch can be selected upward or downward depending on the design of the fastening, and the installation direction of the pivot may be formed from the inside toward the outside, or vice versa. It is also possible. Also, in order to easily attach the handle member to the sliding groove or sliding latch, when bending on the pressing surface, leave a gap in the opening to allow the handle member to be inserted, and hinge the handle member in the assembly process When it is pushed from the upper end portion 35 toward the lower end portion 33 of the hinge, it can be inserted easily by elasticity and in order to prevent the handle member from being detached from the fastening portion after mounting In addition, the problem can be solved by placing the step on the hinge middle portion 34 or the hinge lower end 33.

  An embodiment of the means for achieving the object of the present invention will be described more specifically with reference to the drawings as follows.

  The embodiment shown in FIGS. 1 to 6 uses a pin as a pressing member, and slightly deforms the outer shape and the structure according to the bending direction and bending size of the sliding latch or sliding groove constituting the fastening portion of the main body However, there is no big difference in the operation system.

  The material constituting the binding clip of the present invention is roughly divided into two parts, but a material such as a main body 10 made by bending a plate material such as a highly elastic metal material and a pin of a high strength metal material And the handle member 20 of FIG.

The main body 10 is bent in the same both directions at a fixed distance based on the body central portion 11 to form a central elastic portion 12 and passes through a pressure surface 14 which is sloped at a fixed inclination angle here, and then elastic. A pair of paper contact portions or pressure contact portions 15 which are in tight contact by force are formed by bending. The tip of the abutment 15 can be slightly flat or rounded to improve the abutment force when paper is inserted. Further, in the conventional clip structure, this portion is always fixed by the hinge-shaped pivot joint, but in the present invention, the position of the fastening portion 30 of the pin is changed to the center of the pressing surface 14. machining Ri is capable name has become possible to change the design of the product.

  The central part 11 of the body becomes bent like a bow in the heat treatment process and bending process, but the restoring force to return to a flat state generates a force to strongly press the paper, and both sides of the central part of the body In the case of the two concentrated elastic portions 12 formed symmetrically, the restoring force acts in the direction of more bending inward to increase the contact force of the paper. At this time, the contact angle α formed by the abutment portions 15 at both ends must be 90 ° or less at all times, preferably 30 to 80 ° in order to form a stable structure. is there.

  A handle member 20 made of a high strength metal wire or a rigid material that can perform the same function is inserted into the 11-shaped fastening portion 30 which is cut on the pressure surface 14 and formed side by side. In order to form the fastening portion as shown in FIG. 1, the H-shaped portion is cut into a shape rotated by 90 ° at the center upper portion of the pressing portion 14 and then both side surfaces are formed. It can be easily formed by rolling up the cutting part, and when inserting the handle member at the final stage of revision, it can be easily pushed in with the appropriate force in the direction of the lower end 33 at the hinge upper end 35 of the sliding groove. It is possible to wear. At this time, in order to prevent the handle member from being disengaged from the fastening portion during use, as shown in FIGS. 1 and 3, a fine separation preventing step 35 on the hinge central portion 34 or the lower end portion 33 of the sliding latch. The problem can be solved by making or performing appropriate shaping so that the same function can be performed.

  The structure of such a connection is equally applicable to the examples of the other drawings.

  When the paper is inserted and fixed by the folder type clip configured as shown in FIG. 1, when the upper end of the handle member 20 is pulled up, the lower end 22 of the handle member is slid until it contacts the lower end 33 of the fastening portion The gap between the abutments necessary for inserting the paper by holding the upper part (21, 23) of the upper and lower handle members projected to the end but protruding with the fingers. Will be secured.

  In the embodiment of FIG. 2, the incision and bending of the fastener is similar to the embodiment of FIG. 1, but with the flexure of the sliding latch of the fastener and the position of the handle member formed in a downward manner, the clip is There is an advantage that the deformation of the fastening portion can be reduced during use. However, when the document is inserted, a space in which the handle member is installed is required between the contact surface of the document and the fastening portion in order for the handle member 20 to be in sliding contact with the paper without sliding against each other. However, in order to solve this, a bend 16 must be formed on the upper side of the pressure abutment. The embodiment shown in FIG. 2 has the advantage that the pin is hidden inside, so that the problem of catching between clips when stacking documents is reduced and the appearance is also beautiful, but compared to the embodiment of FIG. There is a drawback that the shape processing of the incision portion is somewhat complicated.

  FIG. 3 shows the sliding latch of FIG. 2 having a step formed at the lower end of the hinge for preventing the detachment of the handle member.

  The embodiment of FIG. 4 is, as shown in FIG. 1, an example in which the handle member is exposed upward, and in order to form a fastening portion in the main body, as shown in FIG. In this method, the “U” -shaped incisions are formed symmetrically on both sides on the pressure surface at regular intervals, without cutting the middle between the two sides. Since the central portion of the central elastic portion is connected without being separated from the lower pressure contact portion 15, stronger elastic force can be maintained than in the embodiment of FIG. This method is suitable when the area is relatively large and the incision area is sufficient.

  The embodiments of FIGS. 5 and 6 are determined without the H-shape cut across the middle of the pressing surface 14 or the method in which the handle member is installed downward as in FIGS. 2 and 3 described above. In this method, "U" -shaped incisions are formed symmetrically on both sides on the pressing surface at intervals. As noted above, this method is more resilient than the embodiment of FIG. 2 and is suitable for relatively large clip sizes and sufficient incision area.

  FIG. 7 shows a structure in which the curved surface is processed inside the pressure contact portion. When the handle pin is inserted inside, the tip of the pin may scratch the paper or the contact portion of the paper may be damaged by the contact portion of the paper. This structure has the advantage of being able to secure more pin length when inserted.

  FIG. 8 shows an example in which a sliding latch is difficult to form inside due to the narrow width of the clip body, and as an example of a method of forming so as to project on the side, when paper is inserted like a conventional binding clip Since the surface is smooth, there is an advantage that damage to the paper can be prevented.

  FIG. 9 shows some embodiments of handle members made of pin material. The distal end 22 of the handle member is preferably slightly bent so as to prevent the handle member from being detached during use, and it is also possible to make the tip uneven as it is bent.

  Although the specific content and principle of the present invention can be briefly described through the specific examples illustrated in the drawings, this is only the embodiment in which the spirit and scope of the present invention are shown in the drawings. It is to be understood that no limitation is intended, and that the principles of the invention are to be applied to all objects embodied and modified or applied.
