Title:
MANUFACTURE OF LEAF BASE WITH RING OPEN/CLOSURE MECHANISM OF DESK CALENDAR
Document Type and Number:
WIPO Patent Application WO/2010/053211
Kind Code:
A1
Abstract:
Month sheets, a triangle cardboard base, and a binding member of a conventional ring-bound desk calendar are integrally bound and manufactured. Every year such calendars are wastefully discarded separately or as a whole, and this discard is not friendly to the environment. Moreover, the calendars have a disadvantage that the leaves are not replaceable, their manufacturing cost at small lot production is high, and all defective calendars due to misbinding have to be discarded.
A novel desk calendar base is manufactured by means of fabricating three members, i.e., a set of calendar leaves having binding holes, a three-dimensional trapezoidal leaf base serving as a support, and a ring open/closure mechanism serving as a metal leaf hanger, and joining and fixing the open/closure mechanism to the top surface of the base using a screw. To bind the calendar leaves, the user opens and closes the rings with the open/closure mechanism at the top surface of the leaf base and binds the leaves by passing the rings through the holes of the calendar leaves.
In other words, the open/closure mechanism (hang binder) of the novel binder having a hanger portion is made, and a novel file hanger is manufactured by attaching the hang binder to the top surface of the trapezoidal base. As a result, the calendar can be regenerated every year by providing only replaceable calendar leaves to the durable base.
