Description

Document file with punching function

The present invention relates to a document file for filing documents, and more particularly, to a structure of a document file configured to simultaneously perform punching and filing operations when filing documents.

Existing file piles used in many places where papers are handled are mostly piled documents simply punched with a punch punch at a predetermined interval using a separate punch.

In the case of using such a file file, a lot of inconveniences arise because of the need for a separate punch mechanism for punching for filing first. That is, in the state of punching the document first using the punch mechanism, there is a disadvantage that the hassle of filing on these files to be rewound.

In order to solve this disadvantage, many mechanisms having a punching function have been proposed. Such conventional mechanisms can be classified into several types, and for example, a separate punching mechanism is provided in a document file. As such, the use of a separate punching mechanism mounted on the filing file requires that the punching operation and the filing operation must be performed separately, so that the user must first punch the punching mechanism and then refile it. It is raised.

And another configuration is such that punching and filing are performed at the same time. However, in such a conventional configuration, when performing the operation for punching, a disadvantage arises in that the punching function is not performed smoothly because the punch and the punch ball do not perform relatively linear motion. For example, any one of the punch and the punching hole is fixed, and the punching operation is performed while the other side is rotating while the punched document is inserted therebetween. However, this point has been pointed out that the punch and the punch ball does not coincide exactly when the punching is made, this disadvantage is known to be due to the rotational movement of the punch mechanism.

In addition, although it has been suggested that the punching and piling can be substantially implemented together, the configuration thereof is complicated, and thus, the increase in the manufacturing cost and the reliability of the operation are problematic.

The present invention is to solve the problems according to the prior art as described above, to provide a document file configured to be performed at the same time punching and filing of the document.

According to another embodiment of the present invention, the punch member and the guide shaft which is fixed to the pile body upright; A punch assembly including a body accommodated in the guide shaft and moving up and down, and a punch hole part having a punch hole corresponding to the punch member and connected to an upper end of the body to be rotatable; Elastic means for elastically supporting the punch assembly upward; And a locking lever portion contacting the upper surface of the punch hole portion and a handle extending from the locking lever portion to be gripped by the user, and including an operating lever rotatably coupled to one side of the guide shaft; By rotating the handle, the locking lever portion is punched out while the punch body is moved downward, and the lower center of the locking lever portion is fastened in a state while stopping at a point past the vertical center of the guide shaft.

Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

First, Figure 1 is a side view showing the configuration of the first embodiment of the present invention, (a) shows the open state before filing the document, (b) shows the punching and filing state of the document is completed, that is, the closed state will be.

As shown in FIG. 1, the document pile according to the present invention includes a punch member 20 which is fixed upright to the pile body 10, a punch body 30 which moves up and down with respect to the punch member 20, and In addition, the punch body 30 is configured to include an operating lever 40 capable of vertically moving and maintaining a fastened state at a predetermined position.

The punch member 20 maintains the upright and fixed state to the pile body 10, and has a punching portion 22 for punching a document while being inserted into the punch hole 32 at the upper end thereof. The punching portion 22 is formed so that its upper surface is concavely formed, so as to serve as a blade for forming a predetermined punching hole in the document.

The punch body 30 is inserted into the guide shaft 34 fixed to the pile body 10 in a vertical state and configured to be slidable in the vertical direction, and formed in a portion corresponding to the punch member 20. The punch hole 32 is provided. The guide shaft 34 is in a state accommodated in the longitudinal guide hole 31 of the punch body 30, and serves to guide the punch body 30 to move up and down substantially. An elastic spring 36 is interposed between the pile body 10 and the punch body 30, so that the punch body 30 is elastically supported upward.

An operating lever 40 is rotatably coupled to an upper end of the guide shaft 34. The actuating lever 40 serves to lock the punch main body 30 which is elastically supported upward in a downward direction or to lock the punch main body 30 in a state where the bottom dead center is reached. It is.

The actuating lever 40 converts the punch body 30 into a straight downward motion by the rotational movement of the handle 42 while contacting the handle 42 and the upper surface of the punch body 30 that the user holds and manipulates. It consists of a lock lever 44. The handle 42 and the lock lever portion 44 have a predetermined fastening angle a.

Next, the operation of the document file according to the first embodiment of the present invention configured as described above will be described.

In the state shown in (a) of FIG. 1, the document D to be inserted is inserted between the punch member 20 and the punch hole 32. When the handle 42 is rotated in the clockwise direction as shown in the drawing, the end of the locking lever 44 is pressed down by the punch body 30 in contact with the upper surface of the punch body 30. Therefore, while the punch body 30 moves downward, the spring 36 is compressed.

As the punch body 30 moves downward in this manner, the document D between the punch member 20 and the punch hole 32 is substantially punched out due to the downward movement of the punch body 30. After the punching is completed, the piling will be completed while descending along the punch member 20. At this time, the diameter of the punching portion 22 of the upper end of the punch member 20 is formed to be somewhat larger than the diameter of the shaft portion 24 of the lower portion thereof, so that the punched document D is smoothly downward. It would be possible to go down and file it. Through this operation, the document D is completed at the same time of punching and filing.

In the state shown in (b), that is, when the handle 42 is rotated to a substantially horizontal state, the lower center portion of the lock lever portion 44 is substantially left of the center line of the guide shaft 34. In this state, the lower end of the locking lever 44 is brought into contact with the stopper 37 formed on the upper surface of the punch body 30 to be stopped. Looking at this state in detail, since the elastic spring 36 is compressed, it has an elastic restoring force upward. However, the restoring force exerted upward by the elastic spring 36 acts as a force for pushing the lock lever portion 44 upward by the upper surface of the punch body 30, but substantially the lower end of the lock lever portion 44. Since the center part is moved to the left side rather than the center line of the guide shaft 34, the restoring force of the elastic spring 36 acts as a force which substantially adds the locking lever part to the left side, and the operating lever 40 Results in further pressing in a clockwise direction. Therefore, in the state in which the punching and piling is completed through the above process, the elastic spring 36 is to apply the force to the punch body 30 to maintain the fastening state so that the piling state is not dismantled.

And when filing another document in the state as shown in (b) of FIG. 1, or to take out the filing documents again, by rotating the handle 42 of the operating lever 40 counterclockwise (a) While being shown in the state, a predetermined space is secured between the punch hole 32 and the punch member 20 so that the document can be taken out again.

In the first embodiment of the present invention as described above, it can be seen that the rotational movement of the operating lever 40 is converted into a linear up and down movement of the punch body, so that punching and piling are performed together. The technical gist of the present invention is to maintain the state by applying the elastic restoring force in the direction in which the elastic spring 36 can maintain the clamping force, i.e., once it is in the fastened state. It can be seen.

In this embodiment, of course, other modifications are possible with respect to the rotational direction of the operation lever 40. For example, although the operating lever 40 shows an embodiment of operating in a clockwise direction in the drawing, it may be configured to rotate in a direction perpendicular to the ground.

Next, a second embodiment of the present invention will be described with reference to FIGS. 2 and 3. This embodiment uses the basic technical spirit of the above-described first embodiment, but is more specifically implemented.

As shown in FIG. 2, the document file according to the present embodiment has a frame 102 fixed to the file body 110 and a punch body 130 coupled up and down with respect to the frame 102. And, the operating lever 140 for controlling the vertical movement of the punch body 130.

The frame 102 is fixed to the pile body 110, and a plurality of guide shafts 134a, 134b, 134c, and 134d are fixed in an upright state. The punch body 130 is coupled to the guide shafts 134a, 134b, 134c, and 134d through the guide holes 131a, 131b, 131c, and 131d, which are formed in the up and down direction on the punch body 130. do. An elastic spring 136 is interposed between the frame 102 and the punch body 130 to elastically support the punch body 130 upward.

Next, with reference to Figure 3, looks at with respect to the operating lever 140 for moving the punch body 130 up and down. The operation lever 140 is composed of a handle 142 for the user to hold and manipulate, and a locking lever 144 for changing the rotational movement of the handle 142 to the vertical movement of the punch body 130.

As shown in FIG. 3, one side end (the upper end of the locking lever 144) of the operating lever 140 is rotatably coupled to the upper end of the guide shaft 134a through the hinge shaft P. As shown in FIG. . And the lower end of the lock lever 144, that is, the lower end in contact with the punch body 130 is rotatably installed in the roller (R). The angle formed by the line connecting the roller R and the hinge axis P and the center line of the handle 142 is formed at an angle of more than 90 degrees, for example, 93 degrees. Accordingly, when the operation lever 140 is rotated in the clockwise direction, the roll roller R moves to the left side while making a rolling contact with the upper surface of the punch body 130. Due to this left movement, the punch body 130 is substantially lowered, and by this lowering, the punch hole 132 is lowered, and punching of the document by inserting the punch member (not shown in this embodiment) inside. This is done. Subsequently, when the operating lever 140 rotates or reaches a horizontal position, the center of the roller R is positioned slightly to the left of the center vertical line of the guide shaft 134a. Precisely, the line formed by the roller R and the hinge axis P is in a state rotated to the left by a 3 degree interval from the vertical center line of the guide shaft 134a. In this state, the rotation of the operating lever 140 is stopped, and the elastic spring 136 is in a compressed state, thereby pressing the punch body 130 upward. However, at this time, since the roller R provided at the lower end of the locking lever 144 is in a state of being passed from the center line of the guide shaft 134a to the left side, the upward elastic force of the elastic spring 136 is substantially the operating lever 140. This results in pressurizing the clockwise direction, whereby such a fastening state can be maintained.

And when the locking lever 144 of the operation lever 140 applies a downward force only on one side of the punch body 130, the punch body 130 to be moved downward in the left and right balance is lost balance, There is a fear that the operation becomes unstable. Therefore, in this embodiment, it is possible to provide a uniform downward force on the left and right sides of the punch body 130. As shown in FIG. 3, the connecting lever 152 is installed in the horizontal direction so as to be rotatable at the same center as the roller R installed at the lower end of the locking lever 144. The right end portion is rotatably connected to the interlock lever 153 which is rotatably connected to the guide shaft 134b. In addition, a roller (Ra) is installed at a rotational connection portion connecting the interlock lever 153 and the connection lever 152.

According to this configuration, it can be seen that the roller R and the roller Ra are simultaneously moved downward by the connecting lever 152 in the horizontal direction. Therefore, since the punch body 130 is moved downward by maintaining the balance between the left and right by the rollers R and rollers Ra provided at the lower end portions thereof, the punch body 130 is substantially smoothly up and down. You can move.

Next, another configuration example of the operation lever 140 will be described with reference to FIG. 4. This configuration example substantially constitutes the lock lever portion 144 of the operation lever 140 in the same manner as in the embodiment shown in FIG. 1, and the configuration of other parts is completely the same as in the second embodiment. Therefore, detailed description of the same components will be omitted, and will be described through the same reference numerals.

As shown, the operation lever 140 is rotatably coupled to the upper end of the guide shaft (131a) through the hinge shaft (P). The lock lever 144 is formed into a shape bent downward from the handle 142 of the operating lever 140, the lower end of the lock lever 144 is provided with a roller (R). In addition, the stopper 137 may prevent further rotation of the lock lever 144 at a position where the lower roller R of the lock lever 144 passes through the center vertical line of the guide shaft 131a. It is molded in the upper surface of 130).

Substantially, the operation of the document file according to this configuration example will be understood to be completely the same as the second embodiment, except that the locking lever 144 of the operating lever 140 in consideration of the convenience of the configuration of the second embodiment It only replaces the arc shape with the bending of the "L" shape.

Next, another embodiment of the operation lever 140 will be described based on FIG. 5. In this embodiment, when the operating lever 140 moves the punch body 130 downward in contact with the punch body 130 at the left and right sides, the connection lever 152 and the interlock lever 153 shown in FIG. Due to the complexity of the configuration, and so on, the embodiment is shown to be more simple. Also, other components will not be described in detail, and will be described with the same reference numerals.

As shown, according to the present embodiment, the operation lever 140 is hinged to the central portion of the punch body 130, and is configured to press the punch body 130 downward from the center. As shown in the figure, the frame 102 fixed to the pile body includes a plurality of guide shafts 134a and 134b including a guide shaft 134e which is fixed upright in the center portion. The operating lever 140 according to the present embodiment has substantially the same shape as the second embodiment, but differs in that it is hinged to the upper end of the guide shaft 134e at the center of the punch body 130. .

When the operating lever 140 rotates in the clockwise direction, the locking lever unit 144 rotates together, and the roller R installed at the lower end presses the punch body 130 downward. By this operation, the punch body 130 moves downward, and punching and filing of the document will be completed, and the fastening state after the filing is completed is the same as described in the embodiment of FIGS. 2 to 4.

Although the illustration of the punch member and the punch hole is omitted in the description of the above embodiment, it is substantially provided on the opposite side of the punch body 130, which is the same as that shown and described with reference to Figs. In the following description, the same components as those in the first embodiment will be denoted by the same reference numerals, and redundant description thereof will be omitted.

Next, a third embodiment of the present invention will be described with reference to FIG. This embodiment shows an example in which the operating lever is installed at the upper end of the punch body in the first embodiment shown in FIG. 1 so that the operating lever is installed at the lower portion of the punch body so as to reduce the overall height.

As shown in the figure, the punch body 30 having the punch hole 32 on one side is accommodated in the guide shaft 34 upright fixed to the pile body 10 (or a frame fixed to the pile body). It is possible to install. One end of the operation lever 40 is rotatably coupled to the connection lever 210 through the second hinge shaft Pb. The other end (upper end) of the connecting lever 210 is rotatably coupled to the upper end of the punch body 30 via a third hinge shaft Pc. In addition, the intermediate portion of the operation lever 40 is rotatably supported with the guide shaft 30 through the first hinge shaft Pa.

Referring to the operation of the present embodiment, when the document to be iron is inserted between the punch hole 32 and the punch member 20, when the operating lever 40 is rotated clockwise, the first hinge shaft Pa By means of the operating lever 40 to rotate around the connecting bearing 210 is also rotated in a clockwise direction around the third hinge axis (Pc). The punch body 30 is guided by the guide shaft 34 by the rotation operation of the third hinge shaft Pc, and moves downward. When the punch body 30 moves downward in this manner, the punch hole 32 moves downward toward the punch member 20, and the punching of the inserted document is completed, and the punch member 20 is continued by the downward operation. The upper end of the state is inserted into the punch hole (32).

In this state, when the central portion of the second hinge shaft Pb, which is the lower end of the connecting lever 210, is slightly beyond the center line of the guide shaft 34, clockwise of the operating lever 40 The rotation operation of is stopped. The stopping operation may be such that the upper end of the operating lever 40 hits the upper surface of the punch body 30 in which the punch hole 32 is formed, and stops, and the rotation is stopped by installing a separate stopper. It is also possible.

When the operation lever 40 is stopped in this way, the elastic spring 36 is in a compressed state, and has an elastic restoring force to lift the punch body 30 upward, but in practice, such an elastic restoring force moves the connecting lever 210 clockwise. Since it is a force to be pressed by, the operating lever 40 can be maintained in a locked state. In the case of taking out the file or filing a new document, if the operating lever 40 is operated in the reverse direction as described above, the operation will proceed in the reverse order as described above, and the state will be shown in (a).

Next, a fourth embodiment of the present invention will be described with reference to FIG. 7. This embodiment is similar to the first embodiment, but relates to an embodiment configured to more easily retrieve a document.

As shown, according to the present embodiment is characterized in that the punch hole 32 is formed to be rotatably supported by the hinge shaft (Pf) in the upper end of the punch body 30 Doing. Therefore, as shown in (a) in which the file pile is opened, the punch member 20 and the punch hole 31 can be opened at a larger angle, so that the documents already attached to the punch member 20 can be opened. This is particularly useful when taking out or reloading a larger amount of paper into the punch member 20.

As shown in (a) to (c), by rotating the operation lever 40 clockwise, the document D inserted between the punch hole 32 and the punch member 20 is punched out. Since the filing is exactly the same as in the first embodiment, detailed description is omitted.

Next, a fifth embodiment of the present invention will be described with reference to FIG. 8.

This embodiment shows a configuration example in which the third embodiment and the fourth embodiment are implemented together. The same reference numerals are used for the same components, and detailed descriptions of the same components and functions will be omitted.

The punch hole portion 31 in which the punch hole 32 is formed is configured to be rotatably supported by the hinge axis Pf with respect to the punch body 30. And the configuration for moving the punch body 30 up and down, one end of the operating lever 40 is connected to the lower end of the connecting lever 210 by using a hinge axis (Pb) rotatably, the connecting lever 210 The upper end portion of the c) is rotatably connected using the punch hole 31 and the hinge shaft Pg. And the middle part of the operation lever 40 is rotatably connected to the guide shaft 34 by using the hinge axis (Pa).

Looking at the operation of the present embodiment briefly, in the state shown in (a) in the state in which the document to be inserted between the punch hole 32 and the punch member 20, the operating lever 40 in the clockwise direction Rotate Then, the punch hole portion 31 hinged through the connecting lever 210 is rotated in the clockwise direction as shown in (b). And when the operating lever 40 is further rotated in the state shown in (b), the connecting lever 210 hinged to the operating lever 40 is continuously rotated in the clockwise direction, substantially the punch body 30 Is guided by the guide shaft 34 and descends to the state shown in (c). In this process, the punch body 30 is lowered down so that the document D is punched and piled to be completely ironed on the punch member 20.

Next, a sixth embodiment of the present invention will be briefly described with reference to Figs. 9 and 10. As shown, the pile body 10 is provided with a punch mechanism P having various embodiments as described above, and a document D punched and piled by the punch mechanism P is shown. . According to the present embodiment, a stapler S is fixed to one side of the pile body 10. Normally, the stapler (S) is a tool frequently used for partially binding a document. In view of this, in the present invention, the stapler (S) is fixed to one side of the pile body (10). And it is preferable that the stapler S is provided in the space which is not substantially occupied by the said pile mechanism P and the document D. FIG. Therefore, in this embodiment, when the pile main body 10 is folded, it is fixed to the upper end of the center surface 10a which is a space which the said punch mechanism P does not occupy. The stapler S may be installed at the lower end of the central surface 10a.

Next, another embodiment of a punch member particularly advantageous for the present invention will be described based on FIG. In the above-described embodiment, the punch member 20 is formed to have a longer length than the conventional simple punch mechanism. This is essentially configured for filing punched documents. When the length of the punch member 20 is long, the most problematic problem is whether or not the punch hole 32 or 132 is matched. In other words, the punching member 20 and the punch hole 32 or 132 should be in perfect contact with each other so that the punching operation of the document can be performed smoothly.

Therefore, the assembly tolerance of the punch member 20 shown in the above embodiment becomes very strict. This is substantially the upper surface of the punch member 20 is formed in a concave shape, or when viewed from the cross-section is formed in a V-shape, the portion that substantially meets the punch hole 32 or 132 is the upper outer peripheral surface of the punch member 20 . Therefore, if the outer peripheral surface of the upper surface of the punch member and the inner circumferential surface of the punch hole 32 or 132 do not coincide exactly, the punch member 20 does not enter the inside of the punch hole 32 or 132 and the punching operation is not smooth.

In view of this point, the embodiment shown in FIG. 11 shows an embodiment configured to enter the punch hole from the central portion of the punch member 120. As shown, the punch member 120 according to the present embodiment, the mountain portion 122 protruded into a mountain shape from the center portion to the upper portion, and the inclined lower portion 124 formed to be inclined downward from the mountain portion 122 It is composed of Therefore, the outer peripheral surface of the upper surface of the punch member 120 gradually reaches the inner side of the punch hole 32 or 132 while reaching from the portion 120a adjacent to the peak portion 122 to the portion 120b adjacent to the inclined lower portion 124. In contact with the puncher, the punching work is performed.

And both sides of the mountain portion 122 is provided with both end portions 126 chamfered with a curved, it is configured so that the mountain portion 122 can be smoothly guided into the punch hole.

By such a configuration, the punch member 120 according to the present embodiment has a wider allowable tolerance range, so that the production and assembly of each part are excellent.

According to the present invention as described above, by operating the operating lever once in the state of inserting the document between the punch member and the punch hole, the punching and filing of the document is completed, it is understood that the state is completely ironed. Can be.

Therefore, according to the present invention, it can be seen that there is a convenience in use that can completely complete the filing of the document without requiring a separate punch mechanism.
