Description

Files and file mechanisms

The present invention relates to a file that can be filed and a file mechanism by pressing the file object without forming a punch hole in the file object such as a document.

There are various types of files that can be filed by forming two or more punch holes on the left end of a document that is the object of the file using a two-hole punch, etc., and inserting a rod or ring member into the punch hole. Ring files are commercially available.

With this ring file etc., it is necessary to punch with a punch when filing a document, and finally a document with a thickness of about 3 to 5 cm is punched with several hundreds of drilling operations. It takes a lot of cost, and when you want to take out a desired document from among the documents already filed, it is often impossible to take out only the desired document. Many.

Thus, when filing using a punch hole, the cost accompanying filing becomes large and becomes a factor of productivity reduction. Moreover, catalogs, pamphlets, photographs, illustrations, maps, drawings, various important documents, trial evidence documents, etc. are often needed to file without punching holes.
As described above, a file that can file a thick document of about 3 cm or more without punching a hole has been craved for a long time, but has not yet been put into practical use.

As files that can be filed without punching holes in a file object, a lever file described in Patent Document 1 and a binder described in Patent Document 2 are known.
The lever file of Patent Document 1 has a structure in which a document or the like is fixed by the elastic force of a torsion spring, but the maximum thickness of the document that can be filed is about 20 mm.

The binder of Patent Document 2 was previously proposed by the inventors of the present application, but has not yet been put into practical use. The binder includes a base plate, two rod members, an elastic plate, and two lock members rotatably attached to the upper surface of the elastic plate, and the elastic plate has an opening hole through which the rod member is inserted. A cylindrical portion through which the rod member is inserted is formed in the elastic plate at the opening hole portion, and the elastic plate is guided through the cylindrical portion so as not to tilt.

A plurality of engaging teeth are formed in two rows on both front and rear side surfaces of the rod member, and the lock member has a pair of lock claws formed on both sides of the notch. When filing, the document is pressed through the elastic plate, each lock member is rotated, and the pair of lock claws are engaged with the engaging teeth on both the front and rear sides, thereby moving the elastic plate upward. Ban.

JP 2003-335087 A Japanese Patent No. 4415940

In the file of Patent Document 1, a large-sized strong torsion spring is required to make a file of a thick document or the like possible. Since a strong torsion spring is very expensive, the production cost is high. Become. In addition, there is a limit to fixing a thick document or the like because a narrow region at the left end portion of the document or the like is clamped. This file still has the same issues as below.

With a press-type file that files thick documents (for example, documents with a thickness of about 40 mm or more) such as the binder of Patent Document 2, documents are prevented from falling off only by the frictional force acting on the lower and upper surfaces of the document. I was trying. In addition, due to the characteristics of the file mechanism, there is a limit to increasing the pressing force, so that the frictional force for holding the document is insufficient, and it is difficult to prevent the document from falling off.

An object of the present invention is to provide a file and a file mechanism provided with a friction plate having a simple structure capable of strengthening a friction force acting on a file object.

The file of claim 1 is a file for filing a file object such as a document.
A cover member including a front cover, a back cover, and a back display; a base plate fixed to the inner surface of the back cover; a rod member extending perpendicularly to the base member from one end fixed to the base plate;
A pressing plate for pressing the file object toward the base member, the guide plate having a guide hole through which the rod member is inserted, and maintaining a posture orthogonal to the rod member with respect to the base plate A pressing plate that can be moved closer to and away from the rod member, a lock mechanism that locks the pressing plate in the length direction of the rod member with respect to the rod member, and the rod member that cannot move in a direction away from the spine. A friction plate having an engaging portion that engages with the rod member, the friction plate being sandwiched between the file objects in a state where the engaging portion is engaged with the rod member, and at least a frictional force that holds the file object. A friction plate capable of generating a part of the friction plate is provided.

According to the above configuration, in a state where the file object is filed by pressing the pressing plate, the friction plate is sandwiched between the file objects, and a frictional force is generated between the friction plate and the file object. Therefore, when the cover member is held by hand and the file object is suspended in a vertical posture, the file object is affected by the friction force acting from the base plate, the friction force acting from the pressing plate, and the friction acting from both sides of the friction plate. Since it is held by force, when the pressing force is constant and one friction plate is provided, the friction force for holding the file object can be approximately doubled. Further, when two friction plates are provided, the frictional force for holding the file object can be approximately tripled. In addition, when there is a margin in the holding frictional force, the pressing force pressed by the pressing plate can be reduced.

The file according to claim 2 is the invention according to claim 1, wherein the lock mechanism is formed on the side surface of the rod member at a predetermined pitch in the length direction of the rod member and is orthogonal to the length direction. An operating member mounted on the pressing plate so as to be movable in parallel with the engaging groove, and formed in parallel with the engaging groove and from a direction intersecting the engaging groove at an acute angle. An operating member having an engaging blade engageable with an engaging groove in the vicinity of the pressing plate; and a guide portion formed on the pressing plate, wherein the operating member has the engaging groove in the vicinity of the pressing plate; And a guide portion for guiding the operation member so as to move in a direction parallel to an acutely intersecting direction.

According to the above configuration, the wedge blade including the guide portion and the operation member can strongly engage the engagement blade of the operation member with the engagement groove of the side surface portion of the rod member. As a result, the pressing plate does not wobble, and it is possible to prevent a decrease in the pressing force for pressing the file object. Since the wedge mechanism including the guide portion and the operation member can be configured with a small thickness dimension in the length direction of the rod member, it is advantageous in securing a vertical width that can be filed.

Since the file mechanism according to claim 6 is obtained by removing the cover member from the file according to claim 1, the same effect as the file according to claim 1 is obtained.
For the configurations and functions and effects of the third to fifth aspects of the invention, refer to the examples.

As described above, according to the present invention, various effects can be obtained.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The file 1 of the present embodiment is a file for filing a file object such as a document (hereinafter referred to as a document S). The file 1 includes a cover member 2 including a cover 2a, a spine 2b, and a back display 2c, and two sets of file mechanisms 3 attached to the cover member 2. This file 1 is an example of mainly file A4 size document S, but it can also be applied to files that file documents S of various sizes other than A4 size. The cover member 2 is composed of a cardboard or synthetic resin plate member.

In the following description, as shown in FIG. 1, the file 1 is assumed to have a horizontal posture when a document is attached to and detached from the file 1, and arrows F, L, and R are described as being forward, left, and right, respectively.
As shown in FIGS. 1 to 4, the two file mechanisms 3 have the same structure, and are fixed to the front and rear of the left side portion of the inner surface of the back display 2c. The file mechanism 3 includes a metal base plate 4, a rod member 5 attached to the base plate 4, a pressing plate 7, a lock mechanism 8, a thin friction plate 17, and the like. However, the friction plate 17 is not shown in FIG.

The base plate 4 is made of, for example, a steel plate or stainless steel plate having a thickness of about 1.2 mm, and is fixed to the inner surface of the back cover 2c by rivets 4a or adhesion. The rod member 5 is a solid member made of an engineering plastic material (for example, POM), but may be made of a metal material.

The rod member 5 extends upward from the one end fixed to the base plate 4 perpendicularly to the base member 4. The length of the rod member 5 is, for example, 50 mm. One end portion of the rod member 5 is fixed to the base plate 4 with a vertical screw 5a. The cross-sectional shape of the rod member 5 is, for example, a square. The length of the rod member 5 is not limited to 50 mm, and can be set to an arbitrary length in the range of 20 mm to 100 mm.

The size of the cross section of the rod member 5 is, for example, 6 mm × 6 mm, but is not limited to this dimension, and is set to a size according to the length of the rod member 5.

The side surface of the rod member 5 is parallel to the front-rear direction or the left-right direction. In addition, the cross-sectional shape of the rod member 5 may be formed in various shapes other than the square (rectangle, circle, polygon, etc.), and may be configured by a hollow member instead of a solid member.

As shown in FIGS. 4 and 5, a plurality of horizontal and front-rear engaging grooves 9 are formed on the entire left side surface of the rod member 5 at a predetermined pitch (for example, 2 mm) in the vertical direction.
Each of the engaging grooves 9 is a V-shaped groove formed of a horizontal plane and an inclined surface 9a, and the inclined surface 9a is inclined so as to move to the left as it moves upward. The operation will be described later.

The receiving surface 11 capable of receiving the left end portion of the document S is formed on the side surface portion (right side surface portion) of the rod member 5 opposite to the spine 2b.

The pressing plate 7 is for pressing the document S toward the base member 4, has a guide hole 12 through which the rod member 5 is inserted, and maintains the posture orthogonal to the rod member 5. The base plate 3 is configured to be movable in parallel so as to approach and separate from the base plate 3. The pressing plate 7 is made of a metal (for example, stainless steel) pressing plate main body 7a and a plate made of a synthetic resin (but may be made of metal) fixed to the surface of a part (left side portion) of the pressing plate main body 7a. And a block member 7b.

The pressing plate body 7a has a length of, for example, 85 to 100 mm, a width of, for example, 20 to 30 mm, and a thickness of, for example, 1.2 mm. However, these numerical values are merely examples.
As shown in FIG. 4, the pressing plate main body 7a has a horizontal base end portion 7c, an inclined portion 7d inclined downward to the right, and a horizontal front end portion 7e on the front end side. It is formed so that it can be pressed. The pressing plate body 7a may be formed in a horizontal flat plate shape.
Anti-slip tape 14 is affixed to the lower surfaces of the inclined portion 7d and the tip portion 7e. In addition, it is desirable to affix an anti-slip tape on the upper surface of the base plate 4 and its vicinity.

The thickness of the plate-like block member 7b is 4 to 6 mm, for example, and the plate-like block member 7b is fixed to the upper surface of the pressing plate body 7a by a plurality of screws or adhesion.
Since the guide hole 12 through which the rod member 5 is inserted has a predetermined vertical length (for example, 5 to 7 mm), the rod member 5 is formed so as to be inserted in a substantially orthogonal relationship with the pressing plate 7. That is, only a minute gap is left outside the rod member 5 in the guide hole 12.

4 to 8, the lock mechanism 8 can lock the pressing plate 7 with respect to the rod member 5 so that the pressing plate 7 cannot move in the direction opposite to the pressing direction by the pressing plate 7 (upward). That is, the lock mechanism 8 can be switched between a locked state in which the pressing plate 7 cannot move in a direction away from the base plate 4 and a released state in which the locked state is released.

The lock mechanism 8 is formed on the side surface of the rod member 5 at a predetermined pitch in the length direction of the rod member 5 and moves in parallel with the plurality of engagement grooves 9 orthogonal to the length direction and the pressing plate 7. An operating member 15 that is mounted on the pressing plate 7 so as to be able to engage with the engaging groove 9 in the vicinity of the pressing plate 7 from a direction that is formed parallel to the engaging groove 9 and intersects the engaging groove 9 at an acute angle. An operating member 15 having a mating engagement blade 15e, and a guide portion 16 formed on the pressing plate 7, wherein the operating member 15 intersects the engaging groove 9 near the pressing plate 7 at an acute angle. And a guide portion 16 for guiding the operation member 15 so as to move in the parallel direction.

The operation member 15 engages with the engagement groove 9 in the vicinity of the pressing plate 7 so as to be switchable between a lock position where the pressing plate 7 is locked and a release position where the pressing plate 7 is unlocked. 7 is attached. The guide portion 16 is formed on the pressing plate 7 so as to guide the operation member 15. The lock mechanism 8 includes a wedge mechanism as will be described later.

The guide portion 16 is formed in a trapezoidal hole extending horizontally between the pressing plate body 7a and the plate-like block member 7b on the left side of the right half of the first rod member 5 and on the right side of the second rod member 6. . The guide portion 16 is formed of a shallow groove that is recessed from below at the lower end portion of the plate-like block member 7b. The guide portion 16 includes an inclined guide surface 16a formed to guide the operation member 15 so as to move in a direction parallel to a direction that intersects the engagement groove 9 at an acute angle.

The operating member 15 is engaged with the guided groove 15a guided by the inclined guide surface 16a and the engaging groove 9 in a direction that is formed parallel to the engaging groove 9 and intersects the engaging groove 9 at an acute angle. It has a combination blade 15e. The operation member 15 is formed in a trapezoidal shape using a metal plate, and the operation member 15 is cut upward by a guided portion 15a guided by the inclined guide surface 16a, a right end side 15b facing in the front-rear direction. It has a raised and raised piece 15c that is raised, and an operation portion 15d that is bent upward at the front end.

The cut-and-raised piece 15c engages with the inclined groove 16b recessed upward from the guide portion 16 in the wall portion of the plate-like block member 7b, and the guided portion 15a is in contact with the inclined guide surface 16a. The operation member 15 is held and guided so as to move parallel to the inclined guide surface 16a. The right end side 15b is chamfered so that an engagement blade 15e (see FIG. 8) formed on a part of the right end side 15b of the operation member 15 is engaged with the engagement groove 9 in close contact.

In the state shown in FIGS. 5 and 6, the operating member 15 is moved forward as much as possible, the engaging blade 15e is disengaged from the engaging groove 9, and the operating member 15 is positioned at the release position. The unlocked state is movable in the length direction (vertical direction) of the rod member 5.
Next, in order to file the document S, the pressing plate 7 is strongly pressed downward with one hand or both hands, and the operation member 15 is moved backward to the state shown in FIGS. Thus, when the operating member 15 is moved backward as much as possible, the engagement blade 15e is strongly engaged with the engagement groove 9 by the wedge action to be in the locked position where the pressing plate 7 is locked so as not to move. At this time, since the engaging blade 15e slips along the inclined surface 9a and moves downward, and the pressing plate 7 also moves downward, the pressing force for pressing the document S can be strengthened.

When the lock state of the pressing plate 7 is released, the engaging blade 15e is detached from the engaging groove 9 by pulling the operating portion 15d of the operating member 15 forward and moving the operating member 15 obliquely forward. The operating member 15 is in the release position, and the pressing plate 7 is in the unlocked state.

The file mechanism 3 is a thin friction plate 17 having an engagement portion 17 a that is engaged with the rod member 5 so as not to move away from the back cover 2 b, and the engagement portion 17 a is engaged with the rod member 5. In this state, one or a plurality of thin plate-like friction plates 17 that are sandwiched between the documents S and can generate at least a part of the frictional force that holds the documents S are provided.

As shown in FIG. 9, the friction plate 17 is a thin plate made of synthetic resin or cardboard having a thickness of about 1 mm, and both surfaces are non-smooth friction surfaces (rough surfaces).
A pair of ear portions 18 corresponding to the pair of rod members 5 are formed at the left end portion of the friction plate 17, and each ear portion 18 has an engagement hole as an engagement portion 17 a through which the rod member 5 can be inserted. 18a is formed. The friction plate 17 can be formed in an arbitrary shape and size including a region where the pressing force from the pressing plate 7 acts. The lateral width of the friction plate 17 in FIG. 9 is about 1/3 of the lateral width of the A4 size.

As shown in FIG. 3, the friction plate 17 is clamped between the documents S in a state where the pair of rod members 5 are inserted into the pair of engagement holes 18a. Then, when the spine 2b of the file 1 in which the document S is filed is positioned on the upper side, the cover 2a or the spine 2b is gripped by the hand and the document S is vertically hung down, the document S is acted from the pressing plate 7. The file mechanism 3 is held by the friction force acting, the friction force acting from the base plate 4, and the friction force acting from both surfaces of the friction plate 17.

The frictional force of each part is a force determined by the pressing force and the friction coefficient acting on the document S. However, if the friction coefficient is constant, a common pressing force acts on each part, so that one friction plate 17 is provided. As a result, the frictional force for holding the document S is approximately doubled. When the two friction plates 17 are provided in different thickness direction parts, the frictional force for holding the document S is approximately tripled, and when the three friction plates 17 are provided in different thickness direction parts. The frictional force for holding the document S is about four times.
In this way, by utilizing one or a plurality of friction plates 17, the frictional force for holding the document S can be greatly increased, and when there is a margin in the frictional force, the document S is pressed by the pressing plate 7. The force to do can be reduced.

Note that the shape of the engaging portion 17a of the friction plate 17 is not limited to the shape shown in FIG. 9, and may be formed as shown in FIGS. The engagement portion 17 a of the friction plate 17 </ b> A in FIG. 10 includes an engagement hook 19 that engages with the rod member 5. The engaging portion 17a of the friction plate 17B in FIG. 11 includes an ear portion 20 having an insertion hole 20a through which the rod member 5 is inserted. The rod member 5 can be introduced into the insertion hole 20a through the elastic bias of the ear portion 20.

12 is formed into a small rectangular plate including an elongated rectangular pressing area pressed by the pressing plate 7. The engaging portion 17 a is a wire that is fixed to the friction plate 17 </ b> C with a tape 22 and forms a hook portion 21 that can be engaged with the rod member 5. The end of the wire is fixed to the friction plate 17C with a tape material 22. In addition, the shape of the friction plate and the shape material of the engaging portion 17a can be freely set.

As shown in FIG. 13, in the state where the document S is strongly pressed by the pressing plate 7 and filed, the rod member 5 is elastically deformed into a gently curved shape by the bending moment acting from the pressing plate 7 and pressed against the document S. It is comprised so that the elastic force of a direction may act.

The operation and effect of the file 1 and the file mechanism 3 described above will be described.
In the file 1 and the file mechanism 3, the file S can be surely filed by a simple operation without punching the document S. Therefore, the time required for the work accompanying the filing of the document S can be greatly shortened. Further, when taking out the filed document S, only a desired document can be taken out with a simple operation. When browsing the document S that has been filed, if it is difficult to view the document S when pressed by the pressing plate 7, the document S can be taken out from the file and viewed. Since the hole is not made in the document S, the document S is not damaged.

In the lock mechanism 8, the wedge blade 15 e including the guide portion 16 and the operation member 15 can strongly engage the engagement blade 15 e of the operation member 15 with the engagement groove 9 on the side surface portion of the rod member 5. The pressing plate 7 does not wobble with respect to the rod member 5, and a decrease in pressing force for pressing the document S can be prevented. Since the wedge mechanism including the guide portion 16 and the operation member 15 can be configured to have a small thickness dimension in the length direction of the rod member 5, it is advantageous in securing a vertical width that can be filed.

Modification 1 (see FIG. 14)

When the pressing plate 7 is switched from this state to the unlocked state, the operating member 15B is moved to the left by pushing the operating portion 43, and the engaging blade 45 is detached from the engaging groove 9 to lock the operating member 15B. The release position is reached, and the pressing plate 7 is unlocked. Note that a resilient elastic member such as a rubber piece may be attached to the left gap 41a of the operation piece 43 in the standing groove 41, and the operation member 15B may be urged to the lock position.
