DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file binder for binding loose leaves and the like.

[0002]

2. Description of the Related Art Among various conventional binders, there is provided a binder comprising a fixed frame A and a rotating frame B as illustrated in FIG. FIG. 7 is a side view seen from the arrow D when the fixed frame A and the rotating frame B in FIG. 6 are combined, and FIG. 8 is a diagram showing the engagement state between the hook 5 and the hook 8 in FIG. It is sectional drawing when seen from EE. A ring-shaped binding claw 3 stands on the rotating frame B of the binder, and has a shaft 6. The shaft 6 is fitted in a bearing recess of a downwardly open bearing portion 7 provided in the fixed frame A, so that the rotating frame B rotates around the shaft 6 as shown in FIG. The loose leaf can be bound by closing the upper end of the short binding nail 2 standing on the fixed frame A. In order to ensure that the binding claw 3 abuts on the binding claw 2 in the bound state, the lever 1 provided with the hook 8 on the rotating frame B and the hook 5 on the fixed frame A at both ends of the binder. It is prepared. Both ends of the hook 8 of the rotating frame B face outward in the longitudinal direction of the binder, and the hooks 5 of the fixed frame A face inward in the longitudinal direction so as to engage with the hooks 8.

[0003] With the configuration including the hooks 5 and 8 as described above, the hook means of the binder has achieved its purpose. However, since the hooks 5 and 8 are slightly protruded in a direction perpendicular to the plane including the ring-shaped binding claws 2 and 3, the hook 5 is merely touched with the finger contact surface 7 by mistake. In some cases, the lock 8 was released from the hook 5 to release the lock.

Another conventional problem is that, as shown in FIG.
In this case, the binder becomes bulky and takes up space because of forming a ring shape.

[0005]

Therefore, in the present invention, these hook means are hooks projecting in a direction perpendicular to the longitudinal direction, and one of the hooks extends in the longitudinal direction by an appropriate length. Make the configuration that was made. The present invention also provides
Most of the binding claws provided on the rotating frame are formed so as to have a flat trapezoidal shape when viewed from the longitudinal direction, and the fixed frame is not provided with the binding claws. Is configured. Note that the fixed frame has a minimum number of fixed side binding nails, which is a minimum limit, so that the loose leaves do not fall off when the binding nails of the rotating frame are opened. It is shortened so that it has the same size and shape as other trapezoidal binding rings as a whole. More specifically, the binder of the present invention comprises a fixed frame, and a binder in which a rotating substrate is pivotally mounted along one edge extending in the longitudinal direction of the fixed frame. The binding nails are erected at intervals, and a finger support plate is provided at both ends of the rotating substrate, protruding in a direction orthogonal to the longitudinal direction, and the finger support plate has an upward hook. A stop member protrudes downward, holes are formed at both ends of the fixed frame body into which the locking member enters, and downward hooks with which the upward hooks are engaged are formed on the wall of the hole. The hooks of the hooks extend in such a manner that the hooks do not easily come off in the longitudinal direction, so that the hooks are locked from a direction perpendicular to the longitudinal direction, thereby making the hooks easy to use. Must be able to come off The features. The hole of the fixed frame has an enlarged portion at a position adjacent to the locking portion of the downward hook. To release the lock, the hooks can be removed only by pressing the finger support plate toward the enlarged portion of the hole and displacing both hooks sufficiently in the longitudinal direction. If the length in the longitudinal direction of the downward hook is extended to such a degree that it does not easily disengage even in the case of unexpected contact,
The hooks are not engaged or disengaged by just touching the finger contact surface, and the binder is not unexpectedly opened. More preferably, as described above, the locking means having such a structure is formed so that most of the binding claws provided on the rotating frame body have a flat trapezoidal shape when viewed from the longitudinal direction, and are fixed. The frame body is not provided with a binding nail, thereby forming an overall flat binder. Note that the fixed frame has a minimum number of fixed side binding nails, which is a minimum limit, so that the loose leaves do not fall off when the binding nails of the rotating frame are opened. It is shortened so that it has the same size and shape as the other trapezoidal binding nails as a whole. When such a flat binder is used, a flat leaf binder can be formed, and it can be suitably used as a binder for binding a hospital chart. Hereinafter, examples of the present invention will be described in detail.

[0006]

FIG. 1 is an overall plan view of a binder 10 according to the present invention. 2 to 5 are cross-sectional views of the binder binder 10 of FIG. 1 cut along lines AA, BB, and CC to open the binding nails of the binder. The closed state is indicated by a dashed line. The present invention will be described with reference to these drawings. The binder 10 includes a plurality of binding nails 2
A rotating frame body 20 having a cylindrical base portion 22 that stands up at a predetermined interval and finger resting plates 24 having hook means 23 at both ends thereof, and each of the plurality of binding claws 21 is inserted into an insertion hole 31. Frame comprising a housing 32 having a semi-cylindrical cross-section for receiving and holding the column base 22 from the back side and receiving and holding the same, and substrates 35 provided at both ends with locking holes 34 for locking the hook means 23. 30.

[0007] As described above, the rotating frame 20 has a cylindrical base 2 having a plurality of binding claws 21 that stand up at predetermined intervals.
2 and finger pads 24 provided at both ends thereof. The binding nail 21 has an "L" -shaped 21a and an "I"
There is a character shape 21b. A hook means 23 having an upward hook 23 ′ on the lower surface of the tip thereof
, A spring mounting part 25, a spring foot fixing part 26, and a finger contact surface 27. As shown in FIG. 4, the torsion spring 50 is attached to the spring mounting portion 25. Hook means 23
Is removed, the binder is opened by the action of the spring 50. When the binding claws 21a and 21b abut against each other, the upward hook 23 'penetrates into the engagement hole 34 at the reference numeral 53 and engages with the downward hook 33 provided in the engagement hole 34. As shown by the dashed line, in the closed state, the binding claw 21a has a substantially flat trapezoidal shape. On the other hand, the binding claws 21b are provided at only four places as shown in FIG. 1, and have recesses formed at their tips, and when closed, they come into contact with the upper ends of the columns 38 rising from the fixed frame 30 and the projections 40. Can be combined. These binding claws 2
1b and the support post 38 form a flat trapezoid having the same dimensions and shape as the other binding claws 21a as a whole. The support post 38 prevents the loose leaves from falling apart when the binding nail 21 is opened. Thus, as shown in FIG. 2, the binding nail has a height h which is much lower than that of the conventional ring-shaped binding nail, so that the overall thickness is reduced.

As shown in FIGS. 3 and 4, the fixed frame 30 is
Each of the plurality of binding claws 21 has an insertion hole 31 through which each of the plurality of binding claws 21 is inserted, and has a housing portion, that is, a bearing 32 for housing and holding the column base 22. At several places along the longitudinal direction of the storage part 32, the detents 41,
41 is formed, so that the column base 22 can be resiliently pushed into the accommodation portion 32 and held at the predetermined position shown in the figure during assembly. Further, the substrate 35 of the fixed frame 30 is shown in FIG.
As shown in the figure, a locking hole 34 having a downward hook 33 for locking to the upward hook 23 is provided at both ends. As can be seen from FIG. 4, the periphery of the upper surface of the locking hole 34 is thick. As can be seen from FIGS. 2 and 3, the substrate 35 has a concave portion 36 in which the tip of the L-shaped binding claw 21 a is accommodated, a support column 38 for supporting the tip of the I-shaped binding claw 21 b, and a plurality of mounting holes 39 (FIG. 1). A concave portion 28 is provided at the distal end of the I-shaped binding claw 21b, and engages with a protrusion 40 provided at the distal end of the support post 38 to limit the movement of the I-shaped binding claw 21b. The column 38 is used to prevent the loose leaf from coming off the fixed frame 30 when the binding nail 21 is opened.

FIG. 5 shows the locking hole 3 below the substrate 35 of FIG.
FIG. 4 is an enlarged plan view showing only 4 of FIG. The locking hole 34
As shown in the figure, it has an L-shape including an enlarged portion 52 and a narrow portion 53, and the downward hook 33 is provided on the hole wall surface on the 51 side of the narrow portion 53. The downward hook 33 is the upward hook 2
It extends for a distance d such that the engagement with 3 'does not easily come off. In order to release the engagement between the downward hook 33 and the upward hook 23 ', if the tip of the finger pad 24 is pushed in the direction of the arrow beyond the distance d to the reference numeral 52, the hooks slide and come off. On the other hand, the binding claws 21a and 21b
When the finger pad 24 is depressed so as to abut, the upward hook 23 ′ moves under the elasticity of the hook means 23 to the reference numeral 5.
The edge on one side enters the locking hole 34 while receiving a force outward, and resiliently engages with the downward hook 33.

[0010]

That is, the upward hooks and the downward hooks are arranged in the width direction of the fixed frame, while the finger pad is hard to extend in the width direction, so that it is hard to come off in that direction. Then, the finger pad easily bends and stretches in the longitudinal direction of the fixed frame, but by setting the engagement length d to a predetermined length, accidental detachment can be prevented. As described above, if the length of the downward hook extends in the longitudinal direction to such a degree that the hooks are not easily disengaged even in the case of unexpected contact, the hooks do not engage and disengage with each other just by touching the finger contact surface. There is no opening of the binder nail. Furthermore, since the binder of the present invention is generally flat and thin, it takes no space and is convenient for storage.

While the preferred embodiment of the invention has been illustrated and described, what is currently considered, those skilled in the art will appreciate that
It will be apparent that various changes and modifications can be made without departing from the spirit of the invention. All such changes and modifications are to be included in the spirit of the present invention.
