(1) When the lever is inserted through the cam, the hinge pin becomes an obstacle, and it is necessary to avoid interference between the lever and the hinge pin.
(2) Even in the case of (1) above, there is a problem that a thinner bearing portion is preferred.

  The present invention is a further improvement of the conventional binding tool as described above.

The present invention includes a bearing, a shaft fitted to the bearing, and a rotating member that rotates with respect to the bearing.
The rotating member includes a through-hole through which the shaft passes and a connecting hole in any direction perpendicular to the direction through which the through-hole passes.
The connecting member with the rotating member is inserted into the connecting hole, the portion of the connecting member that is inserted into the connecting hole is concave, and the shaft is inserted with the connecting member inserted into the connecting hole. When inserted through the through-hole, the member is a mechanism for attaching the member to the bearing in which the concave portion turns around the shaft.
For this reason, a bearing part can be made thin compared with the case where the hole which a shaft penetrates is provided in the connection member with a rotation member.

  The present invention is a member attaching mechanism to a cam in which the rotating member is preferably a cam.

  The invention of the present application includes a first binding member and a second binding member in a semi-ring shape in which the position of the base end portion is fixed and rotatable with respect to the cover body, and the front end portions can contact each other, and the first binding A first connecting member that is connected to the member, a second connecting member that is connected to the second binding member, and the first connecting member that is provided on the opposite side of the cover body with respect to the first connecting member and the second connecting member. And a cam for rotating at least one of the second connecting member, a bearing for restricting the rotating shaft of the cam to a predetermined position on the cover body, an operating means having a base end connected to the cam, and a first connecting member And a biasing means for biasing the second connecting member in a direction in which the front ends of the first binding member and the second binding member are separated from each other.

  The cam of the first binding tool has a cam surface formed at a predetermined angle, a shaft hole through which a hinge pin passes through the side surface of the cam and communicates with the other side surface, and is substantially perpendicular to the extending direction of the shaft hole. An operating means hole that is oriented in the direction and into which the proximal end portion of the operating means can be inserted and removed.

The hinge pin of the first binding tool is fitted to the bearing.
In the operating means of the first binding tool, the hinge pin can be inserted through the shaft hole in a state where the base end portion of the operating means is inserted in the hole for operating means, and is fitted to the inserted hinge pin. A concave portion is provided in which the hinge pin is recessed from the side wall side to the other side wall side of the operating means hole.
Thereby, compared with the case where the shaft hole which lets a hinge pin pass is provided in the base end part, the height of a base end part can be restrained, Therefore The height of a cam can also be restrained.
Specifically, when a shaft hole through which the hinge pin is passed is provided in the base end portion, the base end portion is raised to a certain height in order to surround the shaft hole in order to form the shaft hole. It will be necessary to make it the structure provided with. Therefore, in particular, when the operating means and the cam are separate parts, the cam is required to have a certain height in order to accommodate the base end portion of the operating means, as compared with the case where both are integrally formed. It will be.
Therefore, when closing a document with a binding tool or turning a document or the like bound with a binding tool, it is easy to cause a problem that the operation means or the cam becomes an obstacle.
However, as in the configuration of the present invention, instead of providing a shaft hole in the base end portion and letting the hinge pin pass therethrough, not only suppressing the height of the base end portion by providing a recess instead of the shaft hole, The height of the cam can be suppressed.
Therefore, it is possible to prevent the operation means and the cam from interfering when closing the document with the binding tool or turning the document or the like bound with the binding tool.

It is desirable that the concave portion of the first binding tool is provided along the length direction of the hinge pin and is configured in a substantially semicircular shape that matches the shape of the hinge pin.
Thereby, it is possible to easily insert the hinge pin into the cam in which the base end portion of the operation means is accommodated.

In the closed state where the first binding member and the front end of the second binding member are in contact with each other of the first binding tool, the side where the recess is not provided is close to the first connection member and the second connection member. It is desirable that the base end portion of the operating means is attached to the cam.
As a result, when the connecting member is pushed down, the urging force of the urging means becomes the strongest. Especially when the operating means is made of metal and the cam is made of resin, the side of the cam that contacts the connecting member is made Can be reinforced.
Moreover, the amount exposed above the binding tool can be reduced because the side where the thick concave portion is not provided on the connecting member side in the closed state comes. Therefore, when closing the document with the binding tool or turning the document bound with the binding tool, the operation means and the cam can be prevented from being obstructed, and the binding member can be made small. .

  The invention of the present application includes a semi-ring-shaped first binding member fixed to the cover body, a position of the base end portion that is constant and rotatable with respect to the cover body, and a distal end portion of the first binding member. A semi-ring-shaped second binding member that can be contacted, a second connection member that is connected to the second binding member, a cam that is provided on the opposite side of the cover body with respect to the second connection member, a rotation of the cam This is a second binding tool including a bearing that restricts the moving shaft to a predetermined position on the cover sheet, and an operation unit having a base end connected to the cam.

  The cam of the second binding tool has a cam surface formed at a predetermined angle, a shaft hole through which the hinge pin passes through the side surface of the cam and communicates with the other side surface, and is substantially perpendicular to the extending direction of the shaft hole. An operating means hole that is oriented in the direction and into which the proximal end portion of the operating means can be inserted and removed.

The hinge pin of the second binding tool is fitted to the bearing.
The operating means of the second binding tool is configured such that the hinge pin can be inserted through the shaft hole in a state where the base end portion of the operating means is inserted into the operating means hole, and is fitted to the inserted hinge pin. A concave portion is provided in which the hinge pin is recessed from the side wall side to the other side wall side of the operating means hole.
As a result, even with a so-called single-open binding tool, the height of the base end portion can be suppressed compared to the case where a shaft hole through which the hinge pin is passed is provided at the base end portion, and thus the height of the cam can also be suppressed. Can do.
Specifically, when a shaft hole through which the hinge pin is passed is provided in the base end portion, the base end portion is raised to a certain height in order to surround the shaft hole in order to form the shaft hole. It will be necessary to make it the structure provided with. Therefore, in particular, when the operating means and the cam are separate parts, the cam is required to have a certain height in order to accommodate the base end portion of the operating means, as compared with the case where both are integrally formed. It will be.
Therefore, when closing a document with a binding tool or turning a document or the like bound with a binding tool, it is easy to cause a problem that the operation means or the cam becomes an obstacle.
However, as in the configuration of the present invention, instead of providing a shaft hole in the base end portion and letting the hinge pin pass therethrough, not only suppressing the height of the base end portion by providing a recess instead of the shaft hole, The height of the cam can be suppressed.
Therefore, it is possible to prevent the operation means and the cam from interfering when closing the document with the binding tool or turning the document or the like bound with the binding tool.

Since each invention of the present application is configured as described above, the following effects can be obtained.
That is, the bearing portion can be made thinner than in the case where a hole through which the shaft passes is provided in the connecting member with the rotating member.

(1) Cover body 100
(2) Binding tool 200

(Cover body 100)
As shown in FIG. 1, the cover body 100 includes, for example, a back cover 101, a back cover 102 connected to the side edge of the back cover 101, and a front cover 103 connected to the side edge of the back cover 102. It is formed from the plate-shaped member.
However, the present invention is not limited to the case of being formed from a single plate-like member, and the back cover 101, the back cover 102, and the front cover 103 are made of different plate members, and are bonded to form the cover body 100. You may make it do.

(Binding tool 200)
The binding tool 200 binds a document or the like, and extends in the longitudinal direction of the spine cover 102 and is attached to the inside of the spine cover 102 via, for example, a rivet R, as shown in FIG.
In the present embodiment, the binding tool 200 is attached to the spine 102, but is not limited to the spine 102 and may be attached to the back cover 101 or the front cover 103.

As illustrated in FIGS. 2 and 3, the binding tool 200 includes the following units.
(1) Housing 210
(2) Binding members 220, 221
(3) Connecting member 230,231
(4) Energizing means 240
(5) Occlusion device 250

(Housing 210)
The housing 210 is made of, for example, a steel material or a resin material, and is formed to extend in the longitudinal direction of the spine cover 102 when the binding tool 200 is attached to the spine cover 102.

As shown in FIGS. 10 and 11, the housing 210 includes the following parts.
(1) Opening part 211
As shown in FIGS. 12 to 14, the opening portion 211 is provided by opening the lower surface side of the housing 210 facing the spine 102, and the housing 210 has a central portion in the short direction (left and right direction; Y direction) at the maximum. It is formed by having a curved shape so as to have a height (Z direction).
As a result, the housing 210 is not provided with the opening portion 211, and material can be saved as compared with the case where the housing 210 is formed in a cylindrical shape, and the housing 210 is closed because the lower surface side of the housing 210 is open. The operation of assembling the device 250 and the connecting members 230 and 231 can be simplified.

(2) Engagement piece 212
As shown in FIGS. 12 to 14, the engagement piece 212 cuts the side edge of the opening portion 211, and the engagement hole 213 is relatively inside the outer edge of the housing 210 (substantially Y). Direction) and the tip is bent outward (substantially in the -Z direction) and formed in a cross-sectional shape.
The engaging piece 212 is bent inward (substantially in the Y direction) from the state shown in FIG. 14 to the state shown in FIG. 15 when the connecting members 230 and 231 are assembled in the housing 210.

  As shown in FIG. 11, for example, two engagement pieces 212 are provided in the longitudinal direction of the housing 210.

Further, as shown in FIG. 13, the engagement piece 212 includes an engagement hole 213 into which the engagement protrusion 232 is inserted.
The engagement hole 213 is an example of a connecting member fixing portion, and a plurality of, for example, two, for example, two in the longitudinal direction (X direction) of the housing 210 is provided, and is configured in a rectangular shape, for example.
Thus, when the connecting members 230 and 231 are assembled to the housing 210, the connecting members 230 and 231 can be positioned by simply engaging the engaging protrusions 232 of the connecting members 230 and 231 with the engaging holes 213.
Further, by engaging the engagement protrusion 232 with the engagement hole 213, the binding members 220 and 221 are hooked to the notch 216 provided in the housing 210 so that the connecting members 230 and 231 move in the longitudinal direction of the binding tool 200. Regulate without relying on anything. As a result, the degree of freedom of the shape of the housing 210 can be increased, and the size of the housing 210 can be greatly reduced.
In addition, by engaging the engagement protrusion 232 with the engagement hole 213, the engagement protrusion 232 is more resistant to impact such as when the file 10 is dropped than when the binding members 220 and 221 are hooked on the notch 216 provided in the housing 210. can do.

  Note that not the engagement hole 213 but a notch into which the engagement protrusion 232 is inserted may be used. However, by forming the hole shape, the engagement is achieved even when the housing 210 is formed of a thin metal plate. There is an advantage that the strength of the piece 212 can be maintained.

  Further, the engagement hole 213 has a function as a hinge for rotating the connecting members 230 and 231 by engaging with the engagement protrusion 232.

(3) Bent piece 214
As shown in FIGS. 11 and 12, the bent piece 214 is formed by bending both side edges of the open portion 211 of the housing 210 inward.
Accordingly, the biasing means 240 can be held and the strength of the housing 210 can be increased.

In addition, it is not limited to the case where it is provided on one side edge of the bent piece 214, and may be provided on both side edges.
Thereby, the biasing means 240 can be easily assembled. Further, it is possible to make it difficult for the biasing means 240 to come off.

(5) Notch 216
As shown in FIGS. 2 and 3, the notch portion 216 is provided by notching the side edge of the housing 210 and for passing the binding members 220 and 221.
The notch 216 assists in positioning of the connecting members 230 and 231 when the connecting members 230 and 231 are assembled to the housing 210. Even after the connecting members 230 and 231 are assembled to the housing 210, the relative positioning is assisted so that the binding members 220 and 221 do not wobble.
It should be noted that the notch width of the notch 216 is desirably a width that contacts the binding members 220 and 221. As a result, the number of contact points between the connecting members 230 and 231 and the housing 210 increases. For example, when a great force is applied to the connecting members 230 and 231 such as when the binding tool 200 is dropped, the engaging holes 213 and the notches are formed in the housing 210. Since the force is distributed and transmitted through 216, the durability of the binding tool 200 can be made extremely high.

  The notch 216 is not limited to the case where the side edge of the housing 210 is notched and provided, and may be a hole. When the hole is used, there is an advantage that the strength of the housing 210 is increased. On the other hand, when the cutout shape is used as in this embodiment, there is an advantage that the binding members 220 and 221 can be easily passed at the time of assembly.

(6) Fixing part 217
As shown in FIGS. 2 and 3, the fixing portion 217 is provided at an end portion in the longitudinal direction (X direction) of the housing 210 and is configured in a planar shape so as to come into contact with the spine cover 102.
Further, as shown in FIGS. 2 and 3, the fixing portion 217 is provided with a hole 217 a for a rivet R for attaching the binding tool 200 to the spine cover 102.

The closing device installation port 218 includes a side plate 218a, a shaft hole 218b, and a shaft hole cover portion 218c.

The side plates 218a are an example of a first portion, and are configured as a pair of right and left in FIG. 4 with the free ends of the side plates 218b facing each other. As shown in FIGS. The center is cut in the longitudinal direction (X direction), and the cut portions are bent so as to face each other above the housing 210 (Z direction). The closing device 250 is provided so as to be sandwiched between the side plates 218a as shown in FIG.
As shown in FIG. 2 and FIG. 12, the housing 210 on the base end side of the side plate 218a is cut out in the left-right direction that is perpendicular to the side plate 218a, and cut out at the approximate center in the longitudinal direction (X direction) of the side plate 218a. The side plate piece portion 218d, which is an example of a second portion obtained by bending a part of the housing 210 downward (−Z direction), is provided, and the side plate piece portion 218d is provided with a shaft hole 218b, which is an example of a hole portion. .
Accordingly, the shaft hole 218b can be located near the surface of the housing 210 or inside the housing 210, and the binding tool 200 can be made thinner.

  Further, the side plate piece 218d has elasticity, and is an example of a rotating shaft of the cam 252 when the closing device 250 is installed in the housing 210 as shown in FIGS. 31 and 32 by using the elasticity. The free ends are bent in the left-right direction so as to be separated from each other by the hinge pin P, and after the hinge pin P has passed, it is restored so that the hinge pin P does not come out downward (in the −Z direction).

The shaft hole 218b functions as a bearing that restricts the rotation shaft of the cam 252 to a predetermined position in the cover body 100, and is provided in each of the side plate pieces 218d of the side plate 218a as shown in FIGS. 250 hinge pins P are passed through.
The shaft hole 218b is formed by bending the shaft hole cover portion 218c.
Thereby, the shaft hole 218b and the shaft hole cover part 218c can be formed efficiently.
The shaft hole 218b may be a dead-end hole that does not penetrate other than the through-hole.

The shaft hole cover portion 218c is an example of a third portion. As shown in FIGS. 2 and 32, the tip of the hinge pin P passed through the shaft hole 218b is opposite to the closing device 250 of the side plate 218a (blocking). Covering from the outside of the device installation port 218).
The shaft hole cover portion 218c is formed by bending a part of the side plate piece portion 218d opened when forming the shaft hole 218b in the same direction as the side plate piece portion 218d.
Thereby, the assembly can be facilitated as compared with the case where the shaft hole cover portion 218c is a separate part.
Specifically, the left and right sides and the lower side in FIG. 11 of the shaft hole 218b are cut, a part of the side plate cut out with the upper side as a hinge is lifted upward, and the distal end side is bent downward, thereby bending the distal end side. The inside is brought into contact with the tip of the hinge pin P.
Thereby, after inserting the hinge pin P into the shaft hole 218b, the closing of the hinge pin P can be prevented and the closing device 250 can be held without preventing the hinge pin P from being removed by caulking or the like.
In other words, when the hinge pin P is not retained by caulking or the like, there is a possibility that the hinge pin P may be pulled out due to an excessive load applied to the hinge pin P portion where force is applied when binding a document or the like. In addition, it is possible to solve the problem that it is necessary to use a tool or the like when caulking, and it takes time to assemble.
Further, by cutting the lower side, when the hinge pin P is inserted, the closing device 250 can be assembled from the opening portion 211 of the housing 210, and the work can be simplified.
In the present embodiment, the upper side is a hinge, but the left side may be a hinge, or the right side may be a hinge.

As shown in FIGS. 3 and 16, the raised portion 234 is at least one of the first connecting member 230 and the second connecting member 231, for example, the upper surface of a substantially central portion in the longitudinal direction (X direction) of the first connecting member 230. As shown in FIGS. 6 and 20, by bending at least one of the first connecting member 230 and the second connecting member 231, for example, the first connecting member 230 in a cross-sectional shape, as shown in FIGS. It is formed.

Further, the raised portion 234 is pushed down (relatively moved in the −Z direction) by the closing device 250 in the closed state of the binding tool 200, and the cam 252 in the closed state in which the tips of the binding members 220 and 221 are in contact with each other. This is to prevent rotation.
Specifically, as shown in FIGS. 6 and 7, when the binding tool 200 is in the closed state, the cam 252 of the closing device 250 comes into contact with the raised portion 234 and is pushed down, and the first connecting member 230, The second coupling member 231 coupled to the coupling member 230 by the connection piece 233 is rotated, and the closed state of the first binding member 220 and the second binding member 221 is maintained.

The raised portion 234 is configured to contact at least a straight line substantially parallel to the cam 252 and the rotation axis of the cam 252 in the closed state, and is connected to the second connecting member 231 as shown in FIG. An inclined surface 234a is provided so that the inner side of the binding tool 200 is higher and the outer side of the binding tool is lower, and the inclined surface contacts the cam in the closed state.
Specifically, in the opened state, the point contact is as shown in FIG. 33, and by operating the closing device 250, the first connecting member and the second connecting member are rotated. As shown in 34, it is formed to be in surface contact.
Accordingly, in the closed state, as shown in FIG. 7, the inner side of the binding tool 200 to which the first connecting member 230 and the second connecting member 231 are connected has a V-shaped cross section, which is inclined in the closed state. The surface 234a is parallel to the cam surface of the cam 252 constituting the closing device 250 and the back cover 102, and the contact area between the inclined surface 234a and the cam surface can be maximized, so that the cam 252 is stable. Thus, the closed state where the urging force of the urging means 240 is strongest can be easily held.
In addition, the problem that the cam surface of the cam 252 and the raised portion 234 tend to come into contact with each other at one point, and either or both of the cam 252 and the raised portion 234 are likely to wear can be solved. it can.

(Biasing means 240)
As shown in FIGS. 3 and 5, the urging means 240 is disposed in the opening portion 211 at the approximate center in the longitudinal direction of the housing 210, and as shown in FIG. 9, the first binding member 220 and the second binding member 221 are arranged. Is urged toward the housing 210 side (Z direction) so that the two are always open.
For example, the biasing means 240 is formed by bending a single steel wire as shown in FIGS.

  Specifically, as shown in FIG. 25, one steel wire is bent into a substantially M shape, one end portion is a first portion 241, the other end portion is a second portion 242, and the first portion. The width direction continuous from 241 is the third part 243, the width direction continuous from the second part 242 is the fourth part 244, and the center in the width direction continuous from the third part 243 and the fourth part 244 is the fifth part 245. Is formed. The fifth part 245 is formed by bending the third part 243 and the fourth part 244 so as to have a predetermined inclination (for example, about 30 degrees) as shown in FIG. 26, and gives an elastic force to the wire. ing.

Further, the third part 243 and the fourth part 244 are bent so that the fourth part 244 is longer.
As a result, as shown in FIG. 5, the raised portion 234 having a gap on the lower surface side is supported between the upper side and the lower side in the longitudinal direction and supported from the back side, so that the connecting members 230 and 231 are efficiently urged. be able to.
The biasing means 240 is not limited to a bent wire, and may be a leaf spring or a coil spring.

  As shown in FIGS. 5 and 7, the biasing means 240 includes a third portion 243 and a fourth portion 244, one of which is provided with a raised portion 234 among the bent piece 214 and the connecting members 230 and 231, for example, a first connecting member. 230, and after returning the first part 241 and the second part 242 so that they are substantially parallel to each other, as shown in FIG. The end portion is hooked to the hook portion 215 to be assembled to the housing 210.

The occlusion device 250 is installed in the occlusion device installation port 218 and resists the urging means 240 to rotate the first connecting member 230 and the second connecting member 231, and thereby the first binding member 220 and the second binding member. 221 is held in a closed state.

In this embodiment, as shown in FIGS. 3 and 27, the closing device 250 includes an operating lever 251 that is an example of a connecting member and an operating means with a rotating member, and a cam 252 that is an example of a rotating member. Consists of
By using the operation lever 251 and the cam 252 as separate parts, there is an advantage that the operation lever 251 and the cam 252 need not be integrally formed, and can be formed from different materials. That is, the operation lever 251 is formed of a metal material so that it can withstand the weight of the document bound to the binding tool 200, but the metal operation lever 251 has a thin hole through which the hinge pin P is passed. Using the cam 252 that is difficult to drill and easy to process, the closure device 250 can be easily manufactured.

As shown in FIGS. 3 and 27 to 29, the operation lever 251 is a metal bar that opens and closes the binding members 220 and 221, and includes a base end 251 a connected to the housing 210 and a distal end of the operation lever 251. It is composed of an inverted L-shaped operation end portion 251b provided with its side upright.
The operation means is not limited to the metal rod-shaped operation lever 251, and any operation means may be used as long as it has a shape capable of rotating the cam 252. For example, a seesaw-shaped swing lever may be used.

As shown in FIG. 3, FIG. 28 and FIG. 29, the hinge pin P can be inserted through the shaft hole 252c in the state where the base end portion 251a is inserted into the operation means hole portion 252b. A recessed portion 251c is provided so as to be fitted with the inserted hinge pin P so as to wrap around the hinge pin P from the side wall side of the operating means hole 252b to the other side wall side.
As a result, the height of the base end portion 251a can be suppressed as compared with the case where the shaft hole through which the hinge pin P is passed in the base end portion 251a, and thus the height of the cam 252 can also be suppressed.
Specifically, when the shaft hole through which the hinge pin P is passed is provided in the base end portion 251a, the base end portion 251a is provided to some extent in order to surround the shaft hole in order to form the shaft hole. It is necessary to have a configuration with a height of. Therefore, in particular, when the operation lever 251 and the cam 252 are separate parts, the cam 252 has a certain height to accommodate the base end 251a of the operation lever 251 compared to the case where both are integrally molded. Will be required.
Therefore, when the document is closed on the binding tool 200 or when the document or the like bound by the binding tool 200 is turned over, a problem that the closing device 250 becomes an obstacle tends to occur.
However, as in the configuration of the present invention, instead of providing a shaft hole in the base end portion 251a and letting the hinge pin P pass through, a height of the base end portion 251a is suppressed by providing a recess 251c instead of the shaft hole. In addition, the height of the cam 252 can be suppressed.
Therefore, the closing device 250 can be prevented from interfering when the document is closed with the binding tool 200 or when the document or the like bound with the binding tool 200 is turned.
Further, as shown in FIG. 6, the base end 251a is cammed so that the side where the recess 251c is not provided is close to the first connecting member 230 and the second connecting member 231 in the closed state. It is attached to 252.

Moreover, the amount exposed above the binding tool can be reduced because the side where the thick concave portion is not provided on the connecting member side in the closed state comes. Therefore, when closing the document with the binding tool or turning the document bound with the binding tool, the operation means and the cam can be prevented from being obstructed, and the binding member can be made small. .

As shown in FIGS. 3, 28, and 29, the recess 251 c is provided along the entire length (length direction) of the hinge pin P and has a substantially semicircular shape that matches the shape of the hinge pin P.
The concave portion 251c is not limited to a substantially semicircular shape, and may be any shape that matches the shape of the hinge pin P.

The cam 252 is provided at the base end 251a of the operation lever 251 as shown in FIGS. 3 and 27, and as shown in FIG. 30, the first connection member and the second connection according to the amount of operation of the operation lever 251. Rotating at least one of the members to adjust the degree of opening and closing of the binding members 220 and 221, a cam surface 252a formed at a predetermined angle, and a cylindrical hinge pin that passes through the side surface of the cam 252 and communicates with the other side surface The shaft hole 252c through which P passes and an example of a connecting hole, and is directed to one direction substantially perpendicular to the extending direction of the shaft hole 252c, and the hole for the operation means into which the base end 251a of the operation lever 251 can be inserted and removed Part 252b.
As a result, the cam 252 rotates around the hinge pin P connected to the closing device installation port 218 according to the operation amount of the operating lever 251, the cam surface hits the raised portion 234, pushes down the connecting members 230 and 231 and closes the binding members 220 and 221.
