Description

Knower Technology

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binder (also referred to as a file) for pressing a part of a file object such as a document in a stacked state so that the file object can be released. Background art

Light

In the binder, a plurality of holes are formed at one end of a file object such as a document, and the holes are filled with a hole for IJ.

There is a binder that can be filed without being opened. The present invention relates to the latter binder.

Conventional binders of this type include a cover, a base plate, a holding plate, a parallel link mechanism for connecting the holding plate to the base plate, a lever member, and a binder including a torsion panel connected to the parallel link mechanism and the lever member. Widely used for practical use. However, this binder can file a file object with a thickness of about 2.5 to 3 cm, but a structure that files thicker documents has not been put into practical use. Increasing the size of the parallel link mechanism, lever members, torsion springs, etc., makes it possible to file thick file objects, but increases the manufacturing cost and makes it unsuitable for finalizing thin file objects.

On the other hand, the inventor of the present application has proposed a file pressing tool that can file both thin and thick file objects as disclosed in Japanese Patent Application Laid-Open No. 2001-260582. The file pressing device is a cover, a base plate, a pressing plate, a pair of trapezoidal leg-shaped links connecting the base plate and the pressing plate, and a guide mechanism for guiding the lower ends of these links to be movable in the horizontal direction. A guide mechanism provided on the base plate, and a lock mechanism capable of locking the lower ends of the links so as not to move in the approaching direction and allowing the lower ends to move in the separating direction. When the file object is set and the pressing plate is manually pressed down and moved, the lower ends of the pair of links move in the phase separation direction and cannot move in the phase approach direction, so the pressed state is maintained. can do. this Since the file pressing device has a structure in which elastic force is generated by compressive deformation of the rubber plate fixed to the lower surface of the pressing plate, the width in which the elastic force can be varied is small, the rubber plate is easily deteriorated, and the pressed state is easily loosened. . In addition, there are problems such as a large number of parts, a long and large base plate and a guide mechanism, and high manufacturing costs. In addition, when a thin file object is filed first, the file object is likely to fall off. Is difficult.

SUMMARY OF THE INVENTION An object of the present invention is to provide a binder that can be used for thin and thick file objects without drilling holes and that can be manufactured at low cost with a small number of parts. To provide a binder capable of strongly pressing an object, to provide a binder capable of freely adjusting a pressing force for pressing a file object, and to provide a binder capable of pressing a file object by a simple operation. And to provide a binder that can make the entire file object thinner when the file object is thin, and make the entire file object thicker as the file object becomes thicker.

Disclosure of the invention

The present invention relates to a binder for pressing a part of a file object such as a document in a state where the file object is stacked in a releasable manner, wherein the binder is disposed so as to face at least a part of the base plate from above. And a guide member in a vertical position in which a lower end is connected to the base plate and rises from the base plate, and the elastic plate is moved up and down. A guide mechanism that guides the elastic plate so as to be able to move in a parallel direction in a direction, and the elastic plate cooperating with the guide mechanism so that the elastic plate does not move upward while the file object is pressed by elastically deforming the elastic plate. It is characterized by having a lock mechanism to lip.

When a file object such as a document is filed with this binder, the file object is set, and then the elastic plate is lowered via the guiding action of the guide mechanism with the lock mechanism unlocked. Press the file object to make the elastic plate elastically deformed. When the lock mechanism is activated in this state, the elastic plate The position where the elephant is pressed can be held, and the state where the file object is pressed by the elastic force of the elastic plate can be held. When removing the file object, the file mechanism can be removed by releasing the lock mechanism and moving the elastic plate upward to release the elastic deformation of the elastic plate. It is also possible to configure so that the elastic plate is lowered to press the file object without releasing the lock of the lock mechanism. With this binder, both thin and thick file objects can be filed without drilling holes in the finole object. Since the elastic plate is elastically deformed to generate an elastic force that presses the file object, the amount of elastic deformation of the elastic plate can be freely adjusted according to the thickness, weight and slipperiness of the file object. In addition, it is possible to reliably generate the elastic force required for filing.

Three holes 15 corresponding to the three holes in each row are also formed at the left end of the front cover 2B. For example, when filling a file object P with a thickness of about 2.5 cm or less, align the three holes 15 of the front cover 2B with the three holes 14a of the first row. , And three sets of screws 2 a (see Fig. 11) to connect the cover 1 Connect B. To file a file object P with a thickness of about 5 cm or less, bend it at the position of the bend 13 b, and put the three holes 1 4 b in the second row into the three Align holes 15 and connect with 3 setscrews 2a. To file a file object P with a thickness of about 7.5 cm or less, bend the bent part 13 c and place the front cover 2 B in the three holes 1 4 c of the third groove IJ. Align holes 15 and connect with three sets of screws 2a.

As shown in Figs. 1 and 4, the base plate 3 is made of a plated steel plate and a stainless steel plate, and has a length in the front-back direction of, for example, 10 to 12 cm, and a width in the left-right direction of, for example, 3 to 4 cm. It is fixed to the center of the left end of the back cover 10 in the front-rear direction by a plurality of rivets 16 (see FIG. 1).

As shown in FIGS. 1, 5, and 12 to 15, the elastic plate 4 is made of, for example, a steel panel having a thickness of 0.4 to 0.5 mm and has a length in the front-rear direction. For example, it is 10 to 12 cm, and the maximum width in the left-right direction is, for example, 4 to 6 cm. The elastic plate 4 includes a parallel plate 咅 117 parallel to the base plate 3, two inclined plates 咅 18 extending downward and rightward from the parallel plate portion 17, and a parallel plate portion 17 The inclined portion 18 has a bent portion 19 at the boundary between the inclined plate portion 18 and a curved portion 18a that is bent downward and convex at the right end of each inclined plate portion 18. The width in the front-rear direction of each inclined plate portion 18 is, for example, about 4 to 6 cm, and the height dimension from the parallel plate portion 17 to the lower surface of the curved portion 18 a is, for example, about 1.0 to 1.5 cm. It is. The elastic plate 4 mainly presses the file object P with an elastic force that elastically deforms (bends) the inclined plate portion 17 elastically. However, an elastic force due to the elastic radial deformation of the bent portion 19 is also generated.

As shown in FIGS. 1, 8 to 10, and 12 to 15, the guide mechanism 5 is a rod member 21 having two vertical postures as a guide member 20, Two rod members 21 arranged at a predetermined interval, and two cylindrical portions 23 extending upward from the elastic plate 4 at positions where the two rod members 21 penetrate the elastic plate 4. The outer member slidably fitted to the mouth member 21 without substantial play gap so as to be able to translate along the rod member 21 and not tilt relative to the mouth member 21 2 And two cylindrical portions 23. The rod member 21 is made of a metal (for example, steel or stainless steel) pipe material (for example, an outer diameter of 7 mm and an inner diameter of 5 mm). However, the rod member 21 may be made of a solid round bar. Each rod member 21 can be changed in height in three steps, for example, 3 cm, 5.5 cm, and 8.0 cm.

备 The rod member 21 has a connecting portion 24 that is connected to the base plate 3 so as to be able to be disconnected, and three rod members 21 a, 21 b, and 21 c having different lengths applicable as the rod members 21 are provided. One of the rod members 21 a, 21 b, 21 c having a length selected according to the thickness of the file object P is connected to the base plate 3. That is, there are provided two sets of six mouth members 21a, 21b, 21c that can be used, and any two rod members 21 of the same length are connected to the base plate 3. used. The remaining four rod members 21 that are not connected to the base plate 3 are housed in a synthetic resin bag and stored in a pocket (not shown) on the inner surface of the back cover 11.

The connecting portion 24 is formed of a screw hole formed at a lower end portion of the rod member 21. At a position where the two rod members 21 are connected to the base plate 3, the base plate 3 has a screw hole of the connecting portion 24. A screw hole 25 having the same diameter as the outside diameter of the screw is formed, and a circular hole concentric with the screw through hole 25 and substantially the same diameter as the head of the connecting screw 26 is formed on the back cover 10. ing. The mouth member 21 is fixed to the base plate 3 by connecting screws 26 so that the fixed angle can be removed. However, even in a state where the rod member 21 is fixed to the base plate 3, the rod member 21 can be turned about 90 degrees together with the connecting screw 26 against the frictional resistance. The cylindrical portion 23 is composed of a tubular member 22 (for example, about 5 to 10 mm in length) made of oka or stainless steel penetrated from below into the hole of the horizontal plate portion 17 of the elastic plate 4, and the cylindrical portion Neo 22 is a horizontal plate It has a flange 22a fixed to the lower surface of the portion 17 with a strong metal bonding adhesive (or welding or a screw), and a cylindrical portion 23 that rises vertically from the flange 22a. The flange 22a has a square shape, but may have a circular shape. However, if possible, the cylindrical portion 23 may be formed integrally with the parallel plate portion 17 of the elastic plate 4.

As shown in FIG. 1, FIG. 5 to FIG. 10, and FIG. 12 to FIG. A plurality of engagement teeth 30 formed at small intervals (for example, l mm) in the vertical direction on the surface layer of the rod member 21 over the entire length of the mouth member 21, and correspond to each rod member 21. Member 31 provided in the vicinity of the upper surface of the elastic plate 4 and having a lock claw 32 as well as a non-engagement position where the lock claw 32 does not engage with a position where it engages with the engagement teeth 30. And a lock member 31 whose position can be switched.

A plurality of engaging teeth 30 are formed in two rows on the front side and the rear side of the surface layer of the mouth member 21, and each lock member 31 is related to two rows of engaging teeth 30. It has a pair of lock claws 32 that can be combined. Each lock member 31 is made of, for example, a plate panel material to secure the strength of the lock claw 32. A pair of lock claws 32 is formed on both sides of the notch 33 formed at one end of each lock member 31, and the other end of each lock member 31 is turned horizontally to the bow unilateral plate 4. It is movably connected with rivets 34. Each lock member 31 is formed with a vertically raised operation section 35 for operating with a finger.

A pair of slits 36 for introducing a pair of lock claws 32 is formed in a portion of the cylindrical portion 23 near the upper surface of the elastic plate 4. With the mouth member 21 connected to the base plate 3, grasp the mouth member 21 with a finger and turn the mouth member 21 together with the connection screw 26 around its axis. Thereby, the two rows of engagement teeth 30 can be correctly oriented to the front side and the rear side.

The operation of the binder 1 will be described.

FIG. 1 shows a state in which the file object P is set and the elastic plate 4 has not been elastically deformed yet. When setting the file object P, the front end of the file object P almost coincides with the front end of the cover 1, and the bottom surface of the file object P is It is desirable to set it so that it is supported by the support surface. This is to reduce the load acting on the cover 2 when the binder 1 is stored in an upright posture. Therefore, the length of the cover 2 in the front-rear direction may be set to be approximately the same as the length of the A4 size / letter size, for example. When first setting the file object P on the binder 1, switching the two lock members 31 to the disengaged position allows the elastic plate 4 to move up and down. Ainore object P can be set. When releasing the file object P from the state of pressing the file object P with the binder 1 in order to set the file object P additionally, lower the horizontal plate 17 of the elastic plate 4 with the right hand as necessary. When the two lock members 31 are switched to the non-engagement position with the left hand while pressing, the parallel plate portion 17 of the elastic plate 4 moves upward, and the elastic deformation of the elastic plate 4 is eliminated. Since the plate 4 can be moved up and down, the file object P can be additionally set and filed. To set the file object P in the pressed state after setting, push the parallel plate portion 17 of the elastic plate 4 downward with your right hand while keeping the two lock members 31 switched to the non-associative position, and tilt The curved portion 18 a at the tip of the plate 18 is brought into contact with the file object P. Further, the right and left sides of the horizontal plate portion 17 of the individual plate 4 are strongly pressed down with the right hand, and the elastic plate 4 is appropriately elastically deformed according to the thickness of the file object P. 8 After the file object P is pressed in step a, the two lock members 31 are switched to the engagement positions with the left hand. At this time, the horizontal plate portion 17 of the elastic plate 4 maintains a horizontal position (a position orthogonal to the mouth member 21) by the guiding action of the guide mechanism 5, so that the bent portion 19 of the elastic plate 4 The inclined plate 18 elastically deforms radially. In a state where the two lock members 31 are switched to the engagement positions, the horizontal plate portion 17 of the elastic plate 4 is locked by the lock claw 32 engaged with the engagement teeth 30 so as not to move upward. The elastic deformation state of the elastic plate 4 is maintained, and the pressed state of the file object P is maintained. When the elastic plate 4 is elastically deformed, the curved portion 18a moves slightly to the right, but because of the curved shape, it is easy to slip on the file object P, and the file object P is not damaged. Absent.

Initially, in the state where the thickness of the file object P is small, a rod member 2 la with a length of 3 cm is used, but the thickness of the file object P increases and the height of the rod member 2 la increases. If it becomes insufficient, connect 5.5 cm long rod member 21b to base plate 3 instead of 3cm long rod member 21a and connect front cover 2B. Change the position and increase the width of the back force par 1 1. If the height of the rod member 21b becomes insufficient after that, replace the 5.5cm long rod member 21b with the 8cm long rod member 21c. While connecting to the board 3, the connecting position of the front cover 2B is changed, and the width of the back cover 11 is increased. The binder 1 has the following effects.

Since the file object P is pressed by the elastic force generated by the elastic radial deformation (bending deformation) of the elastic plate 4 composed of the panel panel, the file object P is formed by the elastic plate 4 composed of the panel panel having a simple structure. The required pressing force to file the file can be generated.

Binder 1 can be composed of a few simple structural parts such as force par 2, base plate 3, six rod members 21, one elastic plate 4, two cylindrical members 22 and two lock members 31. Since the guide mechanism 5 and the lock mechanism 6 each having a simple structure are employed, the entire structure of the binder 11 is simplified, the number of components is small, and the binder can be manufactured at low cost. Since the elastic plate 4 is configured to be elastically deformed by pushing the elastic plate 4 by hand, the elastic deformation amount of the elastic plate 4 depends on the thickness and weight of the file object and the slipperiness of the file object P. Can be adjusted to generate the required amount of pressing force. Therefore, when the thickness of the file object P is large, a large pressing force (for example, 6 to 10 kgf) can be generated by increasing the amount of elastic deformation of the elastic plate 4, and the file object P When P is not thick, the amount of elastic deformation of the elastic plate 4 can be reduced to generate a small pressing force (for example, 2 to 6 kgf).

When the thickness of the file object P is small, the rod member 21 having a small height can be used, and as the thickness of the file object P increases, the rod member 21 becomes larger in height. Since the width of the back cover 1 1 of the cover 2 can be changed according to the height of the rod member 21, the binder 1 is convenient to handle the binder 1 and easy to use.

Next, an example in which the binder of the embodiment is partially changed will be described. 1) If necessary, a low friction synthetic resin film may be adhered to the lower surface of the curved portion 18a. Alternatively, a slightly elastic cushion plate made of synthetic resin or rubber may be fixed to the lower surface of the curved portion 18a. Alternatively, a thin sheet made of a low-friction synthetic resin or metal is disposed on the lower surface of the curved portion 18a so as to be relatively movable in the left and right direction and attached to the inclined plate portion 18 so that the file object and the sheet material are It may be configured to generate a slip between them. Alternatively, a low-friction independent thin plate-shaped hard sheet may be arranged on the upper surface of the file object P. 2) When the file object P is pressed, when the inclined plate portions 18 of the elastic plate 4 are manually pressed one by one, the horizontal plate portion 17 is inclined in the front-rear direction. There is a possibility that an excessive bending moment acts on the member 21.

Therefore, as shown in Fig. 16, the horizontal plate part 17A of the elastic plate 4 is divided and the ends of the horizontal plate part 17A can be slid forward and backward through the elongated holes 17a. With rivets 17b. Alternatively, the ends of the divided horizontal plate portions are connected to each other with a rubber plate or a strong elastic woven fabric.

3) As shown in FIG. 17, instead of the two inclined plates 18 of the elastic plate 4, one continuous integral inclined plate 18A is formed. And, if necessary, three or four rod members 21 may be provided.

4) A metal plate (made of mild steel or stainless steel) integrally formed with two cylindrical portions 23 is placed on the upper surface of the horizontal plate portion 17 of the elastic plate 4, and the metal plate is bonded to the horizontal plate portion 17 with an adhesive. Secured by welding, rivets, or screws. Alternatively, as shown in FIG. 18, instead of the tubular member 22, the tubular member is constituted by a tubular body 22 A forming the tubular portion 23 and a nut 46. The cylindrical body 22A has a cylindrical leg portion 47 extending through the hole of the horizontal plate portion 17 of the elastic plate 4 and extending to the lower surface side. A nut 46 is externally screwed onto the leg portion 47. They are fixed to the horizontal plate 17. +

5) If the lock claw 3 2 of the lock member 3 1 is configured to be easily elastically deformed only upward, when the file object P is pressed, the lock plate 3 1 Can be pressed downward to press the file object P.

6) As shown in Fig. 19, two elastic plates 4A are provided independently. In this case, in order to prevent the rotation of the elastic plate 4A, the rod member is formed of a pipe material having an oval cross section or a solid rod material, and the cylindrical portion 23A is formed of an oval cross section. If a plurality of engaging teeth are formed on flat surfaces on both side surfaces of the rod member, the size of the engaging teeth can be increased. When pressing an object, it is only necessary to press one elastic plate 4A at a time to deform it elastically, so that it is easy to use even for users with weak hand such as women and children.

7) As shown in FIG. 20, each of the rod members 21 is composed of a plurality of divided openings 21A which are releasably connected. The length of the split mouth 21A is about 1. 5 to 2 cm, a plurality of engaging teeth 30 are formed in two rows on the surface layer on both sides, and a connecting screw 26 at the lower end of the split port 21A or a split rod adjacent to the lower side. Screw holes 40 into which 21 A screw portions 41 are screwed are formed. At the upper end of the split opening 21A, a screw portion 41 to be screwed into the screw hole 40 of the opposing split rod 21A on the upper side is formed.

Alternatively, a split port 21 B as shown in FIG. 21 may be applied to the rod member 21. The split rod 21B is provided with two rows of engagement teeth 30, a fitting hole 42, and a fitting shaft portion 43 that can be fitted into the fitting hole 42 and releasably connected. Having. Two projections 44 are formed at the tip of the fitting shaft 43. The fitting hole 42 has two vertical grooves into which two convex portions 44 can be introduced, and two arc grooves extending approximately 90 degrees clockwise, for example, clockwise from the deep ends of the two vertical grooves. Have been. The split rod 21B can also be connected sequentially and extended upward. A screw hole into which the connecting screw 26 is screwed is formed in the lower part of the lowermost division opening 21 B connected to the base plate 3.

The above-mentioned split rods 21A and 21B are merely examples, and are not screw-type or top-to-bottom types, but split rods that are fitted from the side in the horizontal direction, or from the main horizontal direction. A split rod of a type that is rotated after fitting can also be adopted. Alternatively, it is also possible to employ a mouth member that can expand and contract in the vertical direction in telescopic.

8) The cylindrical portion 23 may have a structure extending downward from the horizontal plate portion 17 of the elastic plate 4. However, in this case, when the file object is thin, the cylinder portion easily hits the base plate.Therefore, the height of the cylinder portion 23 is set as small as possible, and the allowable elastic deformation width of the elastic plate 4 is set as large as possible. It is desirable to set it to

9) As a structure for connecting the front cover 2B to the connection cover, various connection means other than the set screw 2a can be adopted. Short screws and nuts, fasteners or clips may be used instead of the set screw 2a. Alternatively, steel tape or band is attached to each of the three rows of holes in the connecting cover 1 1 and a permanent magnet band is attached to the inner surface of the one row of holes in the front cover 2B. Alternatively, the front cover 2B may be connected by magnetic force. 10) The distance between the two rod members 21 is set equal to the distance between the two holes (for example, 8 cm) drilled with the two-hole piercing device, and the rod member 2 1 Is set to a size (for example, 5.8 mm) that can penetrate the above two holes. In such a case, if necessary, some file objects should be formed with two holes using a two-hole piercing tool, and those two holes should be filed through two mouth members 21. It may be.

1 1) If the thick file object P is strongly pressed and fixed for a long period of time, the elastic plate 4 may be set and the elastic force may be reduced. When the elastic force of the elastic plate 4 decreases, a thin leaf spring having a thickness of, for example, 0.1 mm is adhered to at least the inclined plate portion 18 of the elastic plate 4 so that the rigidity of the elastic plate 4 It is also possible to increase the moment and increase the elastic force. Alternatively, the elastic plate may be composed of two unfixed elastic plates. Alternatively, the elastic plate may be made of a FRP material in which high-strength synthetic resin fiber, carbon nanotube, or the like is incorporated.
