Description

Double Clips with Plug-in Handle

The present invention relates to an office clip used for separating documents, and it is an object of the present invention to solve the protruding problem of the handle pin, which is the biggest disadvantage of the foldable clip known as a conventional double clip, and to insert the body and the grip member in a pivot- For a clip of a new structure changed in the method.

A general shape of a conventional office double clip is formed by bending a main body made of an isosceles triangle shape and a pivotally coupled portion to be engaged with the handle pin is formed at the tip of the upper and lower main bodies to press the paper .

The pivot joint portion formed at the front end of the main body has a hinge portion formed on the left and right sides to prevent both ends of the bent pin from being inserted and removed, and the middle portion is rounded in a shape similar to the hinge portion so as not to be caught when the paper is inserted.

However, in such a general clip structure, the edges of both ends of the hinge protrude from the cylindrical shape, but they are protruded, so that the paper tends to be easily torn.

Also, since the push handle pin has to act as a leverage, there is a problem that it is structurally protruded out. In order to alleviate the problem, the push handle pin may be rotated and stored. However, when the document is viewed or unfolded, the pin is hindered. That is, the handle pin is larger than the body, so that after binding the document, the document is caught by the pin every time the user turns over the document.

In some cases, the handle pin may be separated and stored, which is very troublesome to reassemble if necessary and may be lost.

In order to solve such a problem, various ideas have been proposed. In the 'foldable clip', a body having a triangular structure similar to a conventional double clip is constructed, and a conventional handle pin Instead, a " C "type insertion structure having a predetermined depth is formed on the upper and lower surfaces of the main body, and a plate member of an insertion type structure serving as a push plate instead of the handle pin is attached to both ends thereof. However, such a folding structure seems to be able to solve the grip problem of an existing clip at a glance. However, since the processing shape of the body and the member is complicated and the manufacturing cost is increased due to the various processing steps, The elasticity of the press plate, the angle of the connecting plate and the guide, and the distance between the fulcrum and the fulcrum of the lever, which are difficult to solve.

In the 'office clips', a joint part is formed so that the middle part of the handle pin is folded to solve this problem more realistically. In order to compensate for the lost lever function, the upper part of the pin directly connected to the main body hinge It is possible to make a fulcrum point by connecting horizontally. The design of this patent is a more advanced form than the previously cited technology, but still has similar problems. The addition of the process and cost increase due to the complicated shape of the clip, the fulcrum of the lever and the interval of the action point are too short, It has a downside.

Registration Utility Model 20-0246782, 'Office Flat Clip' is fundamentally improving the problem by changing the shape of the handle pin and the body fastening part from the hinge type to the rivet type detachable structure in order to solve the problems of the basic type clip structure. . In addition to the relatively complicated or sophisticated machining process, the handle pin is not fixed and it can be turned sideways to solve the inconvenience of the pin. There is still a room for improvement in terms of convenience and function since there is a disadvantage that addition of the process to the installation and pin can be moved to the left and right when the pin is pressed with the finger.

The conventional clamshell type clips have a relatively large force in order to press the handle pin in order to insert the document because the distance between the fulcrum, the action point, and the fulcrum is too long on the principle of the lever, Since the clip is protruded in the upward and downward directions with the document separated, it is difficult to store a plurality of documents or to handle them.

The present invention has been devised to solve such a problem. In particular, by changing the structure in which the hinge is formed at the paper grounding portion or the pressing portion at the front end of the main body, the shape and design of the paper grounding portion are made more diverse The present invention has been made in view of the above problems, and it is an object of the present invention to provide a clamshell clip having an improved structure.

In order to solve the above problems,

In a clamshell clip used to disassemble a document,

The elasticity is generated by bending a thin elongated elastic material composed of one body into a symmetrical shape of an upper and lower isosceles triangle, and when the push handle pin which is fastened to both the upper and lower sides is pressed, the upper and lower portions are opened / closed by the principle of the lever. ;

A guide groove formed in the central portion of the upper and lower symmetrical surfaces of the body by punching and fastened to the handle pin through a pair of grooves formed in the form of sliding latches parallel to the left and right sides;

And a pair of pull pins inserted in parallel in an eleven character shape through the guide groove. When the document is bound, the pull pins are upwardly projected so as to improve the gripping power of the fingers and serve as a force point of the lever. So that the clip is prevented from being caught when the handle pin is inserted downward into the guide groove or when the document is spread. The clamshell clip is a main means for solving the problem.

The present invention provides a foldable clip wherein the length of the handle pin is reduced to a length similar to the length of the main body in order to more effectively solve the above problems. In this case, the sliding latch, It is possible to easily open the pressing portion even with a smaller force in the member having the same elasticity as that of the conventional folding clips even though the distance between the folding portion serving as a fulcrum point and the length of the handle pin is reduced considerably So that it is possible to provide an office clip as a feature.

The use of the foldable clip of the present invention can considerably reduce the size of the push handle pin, thereby solving the problems involved in document browsing or document storage. As the hinge of the existing clip is removed from the folded portion of the end of the main body, It is possible to reduce the problem that the paper touches the edge of the hinge of the printer,

As described above, the conventional foldable clip has a hinge, which is a fastening part of the main body and the pull-tab, formed on the ground, so that the distance between the working point and the fulcrum of the lever in principle is long, The distance between the fulcrum and the action point is reduced to less than half of the length of the body and the length of the handle is reduced to less than half the length of the body. It is possible to obtain an effect of increasing the property.

In addition, since the manufacturing process is not increased or added to the conventional folder type clips, it is economical because there is no rising factor of the manufacturing cost.

Further, when the present invention is applied, the hinge structure, which can not be deformed, disappears, so that the shape of the ground portion can be processed into various shapes such as circular, elliptical, triangular, square, heart and wavy shapes. You can expect.

In the present invention, the handle member can be made using conventional metal pins as well as plate-like materials, thereby satisfying the user's taste in terms of design and convenience.

The first means for achieving the above object is a clip body made of an elastic elongated metal plate and having two or more bent portions 12 formed symmetrically with respect to a metal plate member 13 of a predetermined length, A grounding portion 15 for bending such that the pressing surfaces 14 are bent so as to come into contact with each other and then elastically contacting the end edges 15 of the both ends to fix the paper by elastic pressure when the paper is sandwiched therebetween, And a fastening part 30 formed by cutting and bending such that the knob member 20 or 40 is inserted between the elastic bending part 12 and the grounding part 15 to be horizontally moved And two separate knobs 20 or 40 for opening the grounding part are inserted into the fastening part 30 and are made to be able to protrude and be inserted as they move up and down It characterized.

The second means is an elastic bend symmetrically formed from the central portion of the main body to both ends so as to increase the elasticity of the grounding portion (15) at the distal end, and the symmetrical gap between the two bendable portions is the maximum insertion thickness The internal angle of the elastic bending portion 12 should be appropriately deformed so that the inner contact angle alpha of the two ends is less than 90 degrees. In order to maintain the elastic strength more effectively, Additional bends may also be formed. At this time, the position of the fulcrum to be contacted when the pulling member 20 lifts the fastening portion by the principle of the lever is formed on the outer surface of the elastic bending portion or the cut groove on the bending portion.

The third means is formed by bending a highly rigid fins or plates separated from the main body by a pull-tab, and is formed on the both sides of the pressing surface (14) of the main body by sliding or grooving the fastening portion (30) It is mounted on the sliding latch so that it can be repetitively easily inserted and retracted by manual pushing and pulling operation by user, and it should be made to act as a lever to lift the fastening part by the pressure of the finger when projecting.

The lower end 22 of the pulling member is lowered to the grounding portion 15 of the main body and the upper end portion 20 of the pulling member 20 is pulled down to the grounding portion 15 of the main body, The length between the lower end portion of the knob member and the upper end portion 21 does not exceed 30% of the length from the end of the ground portion 15 of the main body to the upper end of the bent portion 12 so as not to protrude much outside the bend- The lower end (22) of the pulling member is hooked on the lower end (33) of the fastening portion when the pulling member is protruded, so that the end is bent or the jaw is formed so as not to be easily separated.

In order to achieve the above-mentioned object, the fifth means is a fastening portion 30 formed at the center upper end of the both side pressing surfaces 14 so as to be located above the intermediate point between the earthing portion and the elastic bending portion, that is, close to the elastic bending portion , It shall be processed in the form of a sliding groove or a latch so that the pull-tab can be moved up and down along the groove or the cylindrical hole by arranging parallel to the left and right eleven-side shapes with respect to the center point. At this time, the curved direction of the sliding groove or the latch may be selected upward or downward according to the fastening design, and the installation direction of the pivot may also be formed from the inside to the outside or from the outside to the inside. Further, in order to easily fit the knob member to the sliding groove or the sliding latch, the opening of the opening is left so that the knob member can be inserted when the knob is bent on the pressing surface, so that the knob member is moved from the hinge upper end portion 35 to the hinge lower end The hinge middle portion 34 or the hinge lower end 33 may be provided with a jaw so as to be easily inserted by elasticity when it is pushed to the hinge middle portion 34 at a constant pressure and to prevent the pull- The problem can be solved by installing.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

The most common shape of a conventional clamshell clip is as shown in Fig. 13, in which there is no significant change in the clip shape of the early clamshell, and various designs have been presented until recently. However, in terms of easiness of fabrication, Is still preferred.

The quality of clip products that are distributed at low cost can be said to be the most important item in the development of a new clip because it is difficult to practical use if the process and cost increase much compared to the existing products even if the function is good.

According to the various embodiments of the present invention, it is easy to recognize that the process steps and costs are much less than those of the conventional methods.

The embodiments shown in FIGS. 1 to 6 use pins as the pressing members, and there are slight differences in the outer shape and structure depending on the bending direction and the bending size of the sliding latches or the sliding grooves constituting the fastening portions of the main body. However, It can be confirmed that there is no significant difference.

1, the material is largely divided into two parts. The material is composed of a main body 10 made by bending a plate material such as a metal material having high elasticity, and a knob member 20 made of a material having a high strength . The main body 10 is bent again in the same direction at regular intervals with reference to the central portion 13 to form the elastic bending portion 12. The elastic bending portion 12 is tightly contacted with the main body 10 through the pressing surface 14 having a predetermined inclination angle, A pair of grounding portions 15 are formed by bending. The end of the grounding portion 15 may be slightly flattened or rounded to improve the grounding force when the paper is sandwiched. Further, in the conventional clip structure, this portion is always fixed to the pivot joint portion of the hinge type. However, in the present invention, since the fastening portion 30 of the pin is positioned at the center of the pressure portion 14, The room for changing the design of the product has been greatly expanded.

In the central part of the main body, two or more bent parts may be formed in order to impart an elastic force to the grounding part 15 at the end. Generally, two elastic bending parts 12 formed symmetrically on both sides provide sufficient elastic contact force. The bending portion may be additionally formed between the two central elastic portions. In this case, the contact angle alpha at which both ends of the grounding portion 15 meet is necessarily 90 degrees or less, preferably 60 degrees or less, which is advantageous because the grounding portion can be opened with a relatively small force.

The handle member 20 made of a rigid metal material or a rigid material capable of performing the same function is inserted into the eleven-shaped fastening portion 30 formed on both sides of the pressing surface 14 so as to be slidable upwardly and downwardly In order to form the fastening portion as shown in FIG. 1, it is possible to easily form the cut portion by cutting the H-shaped portion in the middle of the pressing portion 14 at a position rotated by 90 degrees and then rolling the cut portion to both sides. It is possible to easily mount the handle member by pushing it in the direction of the lower end portion 33 from the hinge upper end portion 35 of the sliding groove with an appropriate force. In this case, in order to prevent the pull-out member from being detached from the fastening portion during use, a fine separation preventing jaw 35 may be formed on the hinge center portion 34 or the lower end portion 33 of the sliding latch as shown in FIGS. 1 and 3, The problem can be solved by making a proper shape processing so that it can be used.

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

1, when the upper end of the pull member 20 is pulled up, the lower end 22 of the pull member is slid until the lower end 22 of the pull member comes into contact with the lower end 33 of the pull- The upper and lower portions 21 and 23 of the upper and lower knob members projected to the end are pressed and held by fingers to secure the ground interval as much as necessary for inserting the paper.

In the embodiment of FIG. 2, the cutting and bending of the fastening portion is similar to that of the embodiment of FIG. 1, but the bending of the sliding latch of the fastening portion and the position of the pulling member are formed in a top down manner. In order to smoothly move the pull-tab 20 without contacting the paper while the document is inserted, a space is provided between the document fold-up face and the pull-tab to secure the pull- Should be formed. 2, since the pins are concealed in the inside, there is an advantage that the problem of clipping between the clips when laminating the documents is reduced and the appearance is neat. However, compared with the embodiment of Fig. 1, .

FIG. 3 is a view showing a protruding step formed at the lower end of the hinge for preventing the pull-out of the pull-tab in the sliding latch of FIG. 2 described above.

The embodiment of FIG. 4 is one example in which the pull-tab is exposed upwardly as shown in FIG. 1. In order to form a fastening portion in the main body, the middle portion of the push portion 14 is not cut on both sides, And a 'C' -shaped incision is symmetrically formed on both sides of the pressing surface. Since the center portion of the central elastic portion is connected without being separated from the ground portion 15 at the lower side, a stronger elastic force can be maintained than in the embodiment of FIG. 1 or FIG. 2, so that when the size of the clip is relatively large and the area of the cut- This is the right approach.

5 and 6, in the manner as described above with reference to FIGS. 2 and 3, the handle member is provided in a top-down manner, or the inner surface of the pressing surface 14 is laid in an H- And a 'C' -shaped incision is formed symmetrically on both sides. As described above, it is possible to maintain a stronger elastic force than the embodiment of FIG. 2, which is suitable for a case where the size of the clip is relatively large and the area of the incision is sufficient.

In the present invention, not only a pin-shaped pull member but also a plate member-like pull member can be manufactured to have the same function. Several embodiments in which a plate member type pull member is applied from FIG. 7 to FIG. 10 are illustrated.

The structure of the main body can be fabricated in the same manner as the embodiments of FIGS. 1 to 6 described above, and is preferably folded into a flat support instead of a cylindrical sliding latch or hinge.

It is also possible to apply a material such as plastic as well as metal to the handle member, but it is necessary to consider the requirements such as processing process and cost. The advantage of replacing the handle member with the plate shape is that the contact feeling is improved and the clip can be used easily. Also, the texture similar to the body can be expressed from the design aspect, and it is possible to produce various colors according to consumers'

FIG. 7 shows an example of a clip designed to expose the plate-like pull member 40 in a bottom-up manner. The function and operation principle of the fastener of the main body can be sufficiently inferred from the description of the structures in FIGS. 1 and 2, . However, in the example of FIGS. 1 and 3, a pin-shaped material is used as the handle member, so that the folding shape of the sliding latch is also required to form a cylindrical hinge. However, in the case of using the plate- It is preferable to make the insertion groove.

In order to give the front pin material grip member 20 a role as a bent portion of the distal end portion 22 for preventing separation, the plate-like handle member 40 is provided with an appropriate engagement protrusion It is possible to prevent dislocation.

In addition, in order to improve the contact feeling during the sliding operation for inserting and projecting the plate-like handle member, it is possible to improve the convenience of the operation by forming the concave-convex portion 45 like a circular ring pattern on the upper part.

7 and 8 illustrate an example of a top-down design in which the pull-tab 14 is mounted below the pull-tab 14 if the pull-tab is in a bottom-up, . As described above, it is necessary to secure space for the sliding operation of the pull-tab when the top-down type is installed in the plate-type type. (16) There is hardly any deformation of the pull-in portion due to the use of the clip and the problem of colliding the pull- This is an advantage.

FIG. 10 shows an embodiment in which insertion grooves 46 are additionally formed in the handle member so that the volume occupied by the members is reduced and the appearance is very neat.

There is an advantage that the sliding rail 391 of the fastening portion is inserted into the insertion groove 46 of the pulling member to increase the supporting force even if there is no separate support formed on the main body and the protruding portion 45 is provided on the touching portion, And the pattern is engraved to be engraved, you can get a clean and practical appearance. However, since it is difficult to realize such a shape by a general metal plate processing, it is necessary to use a high-strength plastic material satisfying strength and formability. In order to fasten the handle member of the clip shown in FIG. 10 to the main body, it can be easily attached by inserting it through the opening 19 in the middle of the bending elastic portion. In order to prevent the handle member from being detached during projection, It is possible to easily solve this problem by forming the separation preventing tacks 47 such as the partial enlargement of the torsion bar.

11 is a structure in which the pressing ground portion is curved inward in order to prevent the paper from being scratched or damaged by the end portion of the pin when inserting the pin type knob member and to secure a sufficient pin length at the time of insertion, There is an advantage that it can be longer. This method is equally applicable to the plate-like handle structure.

12 shows several embodiments of pin material grip members. The distal end 22 of the pull member may be shaped differently depending on the shape of the fastening portion of the main body. The direction of breaking of the distal end should be opposite to the opening direction of the sliding latch, that is, the direction of the pin insertion portion. So that it can be folded in the same direction due to the convenience of the process of attaching the glass member to the main body.

13A and 13B show that the protrusion of FIG. 13A prevents the tip portion 22 of the pin from being detached in the process of insertion and protrusion, by forming fine protrusions in order to prevent the detachment of the tab member from the sliding groove or the latch. And the protrusion 13b is a safety device for preventing the body 23 of the pin from being released to the opening of the sliding groove. Such a protrusion structure formed in the fastening portion is very effective in continuously and stably using the handle member since the gap is maintained by the force externally applied and the elasticity after the fitting, but maintained by the self-elastic force after the fitting.

13A, 13B and 13C show various structures of the plate-like handle member.

13A shows an example of a handle member of a side rail insertion type. When the slide rail 391 is inserted or inserted after being inserted due to the structure of the barbed hook 43 provided at the lower end, .

13 (b) is a plan view of the tabular pull tab applicable to clips as illustrated in FIGS. 7, 8, 9 and so on. In order to prevent the pull tab from separating from the pull tab, So that when it is inserted, it smoothly enters due to the elastic force of the material, and when the pull-tab is pulled, it is prevented from being separated due to the barbed structure. In this case, a slit 44 like a wedge groove may be formed at the lower end of the plate-like handle as shown in FIG. 13 (c) in order to facilitate insertion at the time of assembly.

As shown in the example of Fig. 13, by forming annular irregularities at the portion where the finger of the pull-tab is contacted, the contactability of the finger can be improved and the sliding operation can be performed well.

Fig. 14 shows a conventional double clip structure.

The detailed description and the principles of the present invention can be easily understood by referring to the specific embodiments illustrated in the drawings, which means that the spirit and scope of the present invention are not limited to the embodiments shown in the drawings, It is to be understood that this applies to all objects that can be modified or applied, including principles.
