Problems solved by technology

Therefore, it is necessary to use an ejector such as a rotary ejector to form the protruding portion whose tip is convex and the concave portion whose inner portion is symmetrically convex around the protruding portion, making the metal mold structurally complicated. , thus increasing production costs
Although the number of sheets to be bound is increased by reducing the thickness of the ring in the radial direction, the protrusion and the recess must still be sized to ensure the joint length, which makes the end of the ring necessary thicker than the diameter of the protrusion and the recess, making it difficult to form thin rings

Embodiment Construction

[0033] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 (a) to (d) show a plastic binder in which the spine 12 is in the form of a thin plate. A plurality of 1 / 2 ring members 13 and 14 are fitted at the upper and lower edges of the longer rear side of the ridge at a constant interval. And the ridge portion 12 and the respective 1 / 2 ring members 13, 14 on the upper and lower edges are joined together via thin hinges to form an integral casting. The difference between the binding clip and the common binding clip is that the spine 12 does not adopt the form of a double hinge. This is because when the binding clip is not manual but mechanically bound, when the binding clip is adjusted before the end of the binding operation, A hinge device with an opening and closing ridge makes it difficult to clamp and maintain the ridge. An engagement member is provided at the end of the 1 / 2 ring member 13 in the upper row, and an engageme...

Abstract

A number of 1 / 2 ring parts (13 and 14) are arranged at constant intervals on both sides of the spine portion (12) of binders, and the spine portion (12) and the 1 / 2 ring parts (13 and 14) on both upper and lower sides are coupled together via thin hinges. As the spine portion (12) is not in double-split hinge structure, which is different from the case of conventional binders, it is ensured that the spine portion is held until the termination of the binding operation when a binding apparatus is used for causing a holding mechanism to clutch the spine portion of the binders so as to set the binders to face the back of sheets of loose-leaf paper and also causing an engaging mechanism to close and engage the 1 / 2 ring parts.

Description

[0001] This application is a divisional application of the application filed on October 29, 2004, the application number is 03809716.8, and the invention title is "binding folder and binding device". Technical field [0002] This application relates to a binding clip for binding loose-leaf paper. Background technique [0003] Plastic binding machines for binding loose-leaf paper and documents punched using a porous paper punch (for example, refer to JP-A-2000-289376) are known. The following will give a brief description of the above type of binding machine. Figures 20, 21, and 22 show a commonly used binding machine, which has a number of 1 / 2 ring members 3 and 4, and the 1 / 2 ring members 3 and 4 are fitted on both sides of the spine 2 at a constant interval, and are respectively A two-part hinge is formed by integral molding. As shown in the above figures, a protrusion 5 is formed at the end of each 1 / 2 ring member 3 in the above column. The protrusion 5 has a protrusion tip, an...
