BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin card ring for binding and binding a plurality of cards such as various cards.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional synthetic resin card ring, in which (A) is a perspective view and (B) is an explanatory side view seen from the side of the locking portions at both ends. is there. This conventional card ring 50 is made of synthetic resin such as polyethylene or polycarbonate, and has a ring-shaped ring body 51 having a projection 53 at one end 52 and a hole 55 at the other end 54. By fitting the protrusion 53 into the hole 55, the card ring 50
However, it is formed in a perfect annular shape, and various cards and the like can be bundled and bound. The protrusions 53 and the holes 55 provided at both ends serve as locking portions. More specifically, the binding method of the card is as shown in FIG.
In the state in which 2 and 54 are locked, a force is applied in the direction of arrow P in the direction of separation of the protrusion 53 and the hole 55 to separate the two, and then the direction of arrow Q in FIG. That is, a force is applied to the both ends 52, 54 in a direction separating them from each other,
It is possible to attach a plurality of cards to the ring main body 51 by widening the interval of 2 and 54 and inserting the end portion of the ring main body 51 into the punch hole of the card in this state, and then,
By fitting the projections 53 at both ends and the hole 55, a plurality of cards can be bundled and bound.

[0003]

In the above-mentioned conventional example, since the synthetic resin is used as the material, the ring main body 51 is deformed due to the flexibility or elasticity of the material. , Both ends 52, 54 of which can move in the directions of arrows P, Q in the figure.
Various cards are bound to the card ring by the shift of 2 and 54. However, in this conventional card ring, due to its material and its structure,
There is a first drawback in that when the both end portions 52 and 54 are deformed in the direction Q away from each other in the state of FIG. 5A, the distance between the both end portions 52 and 54 does not greatly expand. . Furthermore, because of the characteristics of the material, the two ends 52, 54 in the expanded state are in a state in which a force for returning to each other, that is, a force for approaching each other is always applied, There is also a drawback in that it is very difficult to attach a card by fitting a punch hole into the card at this end.

Therefore, in the present invention, a card ring made of a synthetic resin can be sufficiently expanded at both ends, and even in a state where both ends are expanded,
It provides a card ring that is not loaded with a force that causes both ends to approach each other.The problem in this case is that if both ends of the ring are disengaged, both ends of the card ring The spaces between the parts may be easily opened and separated, and the bound cards may fall off. The object of the present invention, however, is to take measures to prevent the ends of the ring from being separated from each other even if the ends of the ring are disengaged.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 4 show an embodiment of the present invention. FIG. 1 shows a first embodiment of the present invention, in which (A) is a perspective view thereof,
(B) is a side surface explanatory view seen from the side of the locking portions at both ends of the card ring 10.

The card ring 10 is entirely made of a synthetic resin such as polyethylene, polycarbonate, Duracon, ABS, etc., and its ring body is composed of two semicircular ring constituent parts 11 and 12, respectively. One end is pivotally attached by the shaft 13. Therefore, these ring constituent parts 11 and 12 can rotate in the direction of the arrow Q in the figure, whereby both end parts 14 and 1 can be rotated.
5 can be moved in a direction away from each other. The cross-sectional shapes of the ring constituent parts 11 and 12 are substantially circular, and the axially attached end parts 16 and 17 are flatly formed in a flat plate shape.

The structure of both end portions 14 and 15 constituting the locking portion of the card ring 10 is as follows. Both ends 1
4 and 15 have the same shape symmetrically. That is, the respective end portions are notched by an appropriate length in the longitudinal direction of the ring so that the cross section has a substantially semicircular shape, and joint surfaces 18 and 19 are formed. The protrusions 21 and 22 are formed on the
The holes 23 and 24 that fit into the 2 are respectively formed into the end portions 15 and 1
It is drilled in 4. At each end 14,15
The holes 23 and 24 are provided on the rear side of the protrusions 21 and 22.
positioned.

With this structure, the projection 21 provided on the one end 14 is fitted into the hole 23 formed on the other end 15, and the projection 22 provided on the other end 15.
Fits into the hole 24 formed in the one end 14,
Both ends 14 and 15 are locked to each other.

FIG. 1 shows a state in which both end portions 14 and 15 are locked.
As shown in FIG. 6B, when both end portions 14 and 15 are locked to each other, both end portions have a substantially circular cross section similar to the ring main body portion and are similar to the ring main body portion. It has an outer shape, and the projections 21 and 22 project from the outer peripheral surfaces of both ends. In this way, the projections 21 and 22 are formed in the hole 2
The reason why the protrusions 21 and 22 are formed to be long so as to protrude from the holes 3 and 24 is to prevent the fitting of the both from being easily disengaged, but the protrusions 21 and 22 do not protrude from the outer peripheral surface of the end portion. Needless to say, it may be formed in the above.

The two ring components 11 and 12 have one end 1 when the two ends 14 and 15 are separated from each other.
4 is displaced in the direction of arrow M, and the other end 15 is pivotally attached by the shaft portion 13 so as to be displaced in the direction of arrow N. The reason is that, when the both end portions 14 and 15 are locked to each other, the both end portions 14 and 15 must be deformed in the direction opposite to the directions of the arrows M and N to lock them. When both are locked, both ends 1
This is because 4 and 15 are maintained in a state in which a force is applied in the directions of arrows M and N, respectively, so that both end portions 14 and 15 are hard to come off.

The method of using the card ring of the present invention having such a structure is as follows. First, both end portions 1 shown in FIG.
In the locked state of 4 and 15, according to the direction of arrow D,
First, a force is applied in a direction (vertical direction in the drawing) in which the joint surfaces 18 and 19 of the both end portions 14 and 15 are separated from each other, so that the protrusions 21 and 22 are separated from the hole portions 23 and 24, and the both end portions 14 and 15 are locked. Is released, and thereafter, a force is applied in the direction in which the end surfaces of both end portions 14 and 15 are separated (lateral direction in the figure) to rotate the ring forming portions 11 and 12 about the shaft portion 13 of the shaft attachment portion. Then, the space between the both end portions 14 and 15 is expanded to an appropriate size. When the both ends 14, 15 are expanded, the both ends 14, 15 can be maintained as they are, and a force such that the both ends approach each other like a conventional card ring. Is never loaded.

In this state, various cards can be attached from the end of the ring. That is, a plurality of cards are attached to the card ring by inserting the end portion 14 or the end portion 15 of the card ring into the punch hole of the card. After installing the card, both ends 1
The projections 21 and 22 of Nos. 4 and 15 can be fitted into the corresponding holes 23 and 24, so that the both ends 14 and 15 can be securely locked, whereby various cards can be attached to the card ring 10. It can be bound. The removal of the bound card can be done by the reverse of the above procedure.

FIG. 2 shows that the projections 21 and 22 have the holes 2 at both ends 14 and 15 of the card ring according to the above embodiment.
3A and 3B are enlarged views of the locking portion in the state of being disengaged from 3, 24, (A) of which is an enlarged side view thereof, and (B) of which is an S-S enlarged sectional view of the previous figure (A). In this figure,
In the embodiment shown in FIG. 1, the ring component 11,
Protrusions 2 provided at each end 14 and 15 of 12
1 and 22 are separated from the holes 23 and 24, respectively, to show the separated state.
As described above, 4 is loaded in the direction of arrow M, while 15 of the ring forming portion 12 is loaded in the direction of arrow N, so that the protrusion 21 abuts the joint surface 19 and the protrusion 22. Is in contact with the joint surface 18.

Moreover, as can be seen from FIG. 2B, the projections 21 and 22 have a semicircular cross section, and the flat surface portion 2
Since the members 5 and 26 are configured to abut each other, when the protrusions are removed from the holes and the ring components 11 and 12 are rotated relative to each other, the state shown in FIG. Two
The flat portions 25 and 26 provided on the rear side of the vehicle 2 collide with each other. The collision of the projections 21 and 22 prevents the ring constituent parts 11 and 12 from rotating, so that the distal end parts 14 and 15 are prevented from rotating.
Is prevented from expanding from the state of FIG. When the card is attached or detached, by further applying a force in the direction opposite to the arrows M and N on the respective ring components 11 and 12 from the state of FIG. 2, the contact between the protrusions 21 and 22 is released. For the first time, the ring components 11 and 12 can be rotated about the shaft attachment portion, and both end portions 14 and 1 can be rotated.
It is possible to widen between the end faces of 5, allowing the card to be installed or removed.

FIG. 3 is a partial plan view of still another embodiment of the card ring according to the present invention, showing the engaging portion as in the previous figure. Also in this embodiment, the configurations of the locking portions of the respective end portions 34 and 35 of the two ring constituent portions that form the ring main body portion are different from those in the above embodiment, and other configurations are the same as those in the above embodiment. It is similar to the form.

That is, these end portions 34, 35 have a semicircular cross section, and the joint surface 18 has two protrusions 2 downward.
1, 21 and two holes 23, 23 are provided, on the other hand,
Also on the joint surface 19, two protrusions 21, 21 and 2
Individual hole portions 23, 23 are provided, and respective end portions 34,
The projection 21 and the hole portion 23 provided on 35 are fitted to each other, and the both end portions 34 and 35 are locked.

In this embodiment, the first embodiment
Similar to the shape, the protrusion 21 is located behind the hole 23.
Due to its structure, the collision of the protrusions causes
It is possible to prevent the spread of both ends.

FIG. 4 shows a shaft mounting portion according to the first embodiment of the present invention shown in FIG. 1, in which (A) is a sectional view taken along line RR of FIG. 1 (A) and (B) thereof. ) Is a TT cross-sectional explanatory view of the previous figure (A). A shaft portion 13 is provided on one of the ring component portions 12 that form the ring main body portion, and a hole portion 2 is formed in the other ring component portion 11.
The shaft portion 13 is fitted to the shaft, and both ring component portions 11 and 12 are axially attached. The shaft portion 13 has a substantially circular cross-section, a large-diameter portion 13h is formed at the tip portion, and a slit 13s is formed on a longitudinal surface including the center of the shaft portion 13.

Further, protrusions 3 that engage with the slits 13s are provided at two locations on the inner peripheral surface of the hole 2. The presence of the protrusions 3 and 3 limits the rotation of the ring components 11 and 12. Due to the presence of the protrusions 3 and 3, the rotation of the ring components 11 and 12 is constantly prevented, and the ends of the ring components 11 and 12 can be prevented from expanding more than necessary. When attaching or detaching the card, regardless of the presence of these protrusions 3 and 3, since the card ring is made of synthetic resin, it is necessary to forcibly rotate the ring components 11 and 12. Since the distance between both end portions can be widened further, no trouble occurs.

The embodiment has been described above, but the form can be changed as follows. The shape of the card ring is an elliptical shape in addition to a substantially circular shape in a plan view.
It can be designed freely as desired, such as a triangle, a polygon, a semicircle, and a semi-oval, and the cross-sectional shape of the ring constituent part that constitutes it can be formed in any shape such as a substantially square shape other than a substantially circular shape. Good. Also in the structure of the shaft portion of the shaft attachment portion, in the first invention, the slit may not be provided in the central portion, or the slit is provided, but the projection that engages with this slit is provided. It is also possible to leave no part.

In any of the above embodiments, the ring forming portion is provided symmetrically, that is, the ring is divided into two equal parts, but the ring forming part is formed asymmetrically. You can also do it. That is, it is possible to reduce the length of one of the ring components.
The configuration of the end of the ring component can also be appropriately designed freely, and the number of protrusions provided at the end is also 1 or 2 within the range satisfying the conditions of the invention described in the claims. As described above, it can be arbitrarily set, and its position can also be freely set. On the other hand,
The holes may be provided in correspondence with the number and position of the protrusions. The joint surface between the end portions can also be configured by a flat surface that is a substantially horizontal surface or a curved surface as in the above embodiment, but the shape of this joint surface can also be freely designed as appropriate. Similarly, the cross-sectional shapes of the protrusions and the holes can be appropriately designed as desired, such as a substantially circular shape, a substantially semicircular shape, a substantially quadrangular shape, a substantially triangular shape, and the like.
