The frame 10 has a bar shape having a length extending from one end of the file cover to the other end. The frame 10 is preferably made of a synthetic resin material having elasticity such as plastic.

The frame 10 may be fixed or detachable to a cover of a file provided with a plurality of sheets inside a rigid cover, but the frame 10 may be used alone without being fixed to a cover such as a file.

The body portion 11 of the frame 10 is formed in a U shape having a downward convex curved surface or both side portions bent at substantially right angles and the ring mount rail 12 is provided on both side ends of the body portion 11 And is formed of a flat surface or a curved surface formed to extend inward. A space is formed between the body part 11 and the ring mount rail 12 so that the lower side of the slide bar 20 is slidably inserted.

A plurality of semicircular bookbinding rings (30) for cover and / or inlay fixing are arranged in the ring mount rail (12) at uniform or nonuniform intervals along the length direction. The bookbinding ring 30 has a substantially semicircular shape so that a circular ring shape is formed when the upper ends of the bookbinding rings 30 arranged on the ring mount rails 12 on both sides are in contact with each other. In this embodiment, the bookbinding ring 30 has a semicircular curvilinear shape. Alternatively, some of the sections may have a straight line shape, so that when the two bookbinding rings 30 are engaged with each other, There will be.

The slide bar 20 has a bar shape having a length corresponding to the length of the frame 10. A guide groove 22 is formed in both sides of the slide bar 20 along the longitudinal direction in which the ring mount rail 12 is movably inserted.

The slide bar 20 is slidably mounted on the frame 10 and is configured to slide the one end of the slide bar 20 by a user so as to vary the interval of the ring mount rails 12 of the frame 10 . To this end, concavo-convex portions are formed on the inner side of the pair of ring mount rails 12 and on the inside of the guide groove 22 which is in contact with the inner side end of the ring mount rail 12, The spacing of the ring mount rails 12 is widened and the spacing of the ring mount rails 12 is narrowed when the concave and convex portions are engaged.

In this embodiment, the concavo-convex portion includes a groove 42 recessed inwardly of the guide groove 22, a protrusion (not shown) protruding from the inner end of the ring mount rail 12 and formed in the groove 42 41).

Therefore, when the slide bar 20 is slid with respect to the frame 10, the guide groove 22 of the slide bar 20 is guided by the ring mount rail 12 to slide the slide bar 20, The groove 42 on the inner side of the guide groove 22 is detached from the projection 41 of the ring mount rail 12 and the ring mount rail 12 is pushed outwardly as shown in Figs. 5B and 6B, (12) and a binding ring (30) associated therewith.

As a result, the upper end of the bookbinding ring 30 can be opened and the book, note, cover and / or inlay of the book can be inserted or removed from the bookbinding ring 30.

In this state, when the slide bar 20 is moved in a direction opposite to the previous direction, the protrusion 41 of the ring mount rail 12 and the groove 42 of the slide bar 20 coincide with each other, The spacing between the ring mount rails 12 becomes narrower by inserting the guide grooves 41 into the grooves 42 and the upper ends of the bookbinding rings 30 elastically come into contact with each other.

The protrusions 41 and the grooves 42 may be formed in various shapes. For example, the shapes of the protrusions 41 and the grooves 42 may be various shapes such as hemispherical dome shape or S shape. Can be formed.

In the above-described embodiment, the concave-convex portion includes a projection 41 formed to protrude from the inner end of the ring mount rail 12, and a groove 42 formed in the guide groove 22 of the slide bar 20 7A and 7B, grooves 42 are recessed at the inner end of the ring mount rail 12 and protrusions 41 are formed on both sides of the slide bar 20 So that the concavo-convex portion can be formed.

It is preferable that a plurality of protrusions 41 and grooves 42 constituting the concave-convex portion are formed at predetermined intervals along the longitudinal direction of the ring mount rail 12 and the slide bar 20.

When the user pushes or pulls the slide bar 20 and performs the opening and closing operations of the bookbinding ring 30 as described above, when the user holds the slide bar 20 and easily operates the slide bar 20, The handle protrusion 25 can be formed at the end portion.

In order to prevent the slide bar 20 from being pulled out of the frame 10, a stopper projection 14 may be formed at the end of the ring mount rail 12 so that the end of the slide bar 20 is hooked.

Figs. 8 to 10B show another embodiment of the slide-opening type ring binder according to the present invention. The ring binder of this embodiment differs from the above-described embodiment in the form of the slide bar 20. Fig. The slide bar 20 of this embodiment is formed such that the guide groove 22 (see Figs. 3 and 4) is not formed and the upper end portion has a width corresponding to the width of the space 13 formed between the ring mount rails 12 And a groove 42 is formed on both sides of the upper end of the slide bar 20 to form a concave and convex portion by mating with the protrusion 41 of the ring mount rail 12. [

8, when the projections 41 of the ring mount rail 12 and the grooves 42 of the slide bar 20 are engaged with each other and the upper ends of the bookbinding rings 30 are in contact with each other, 9, the protrusion 41 of the ring mount rail 12 and the groove 42 of the slide bar 20 are shifted from each other and the ring mount rail 12 is slid, The projections 41 of the slide bar 20 contact both sides of the upper end of the slide bar 20, and the ring mount rails 12 are opened.

In this state, when the slide bar 20 is moved in a direction opposite to the previous direction, the protrusion 41 of the ring mount rail 12 and the groove 42 of the slide bar 20 coincide with each other, The ring mount rails 12 are resiliently restored as the guide rails 41 are inserted into the grooves 42 so that the gap between the ring mount rails 12 becomes narrow and the upper ends of the bookbinding rings 30 elastically come into contact with each other, It does not fall out.

Although a pair of ring mount rails 12 are formed on the upper side of the frame 10 at predetermined intervals in the above-described embodiment, as shown in yet another embodiment in Figs. 11 to 13, A pair of ring mount rails 12 spaced apart from each other in the longitudinal direction may be formed at a lower portion than the upper surface and the slide bar 20 slidably moves between the ring mount rails 12. A groove 42 is formed in the ring mount rail 12 and protrusions 41 are formed on both sides of the lower surface of the slide bar 20 to fit into the groove 42.

In this case, when the projections 41 and the grooves 42 are engaged with each other, both sides of the lower surface of the frame 10 are not subjected to the force externally, Both sides of the lower surface of the frame 1 are opened and the bookbinding ring 30 is pinched and abutted.
