A JIG FOR CRESCENT

摘要

The present invention relates to a jig for installing a crescent with a round mount. The present invention comprises: a contact curved surface (11) which has the same curved surface as the curved surface of a mount (2a); a pair of locking jaws (14′) which protrude from the both rear sides of the contact curved surface (11) and are able to prevent the mount (2a) from being inclined to one side and set an accurate mounting position when being in contact with the edge surface of a window frame; position setting protruding parts (12) which protrude inwards from both inner ends of the contact curved surface (11) and are able to be inserted into concave parts (21) formed on both outer circumference sides of the mount (2a); and an elastic bar (13) which controls the position setting protruding parts (12) in order to be easily attached to and detached from the concave parts (21) of the mount (2a). The present invention formed like the above has effects of: remarkably reducing manpower and time for an installation by rapidly and accurately installing a crescent (200) by the jig (100) when installing the crescent having the mount (2a) of a round shape on the window frame (F); enabling the reuse and recycling of the jig (100) as the jig (100) can be disassembled after the installation; and contributing to the high quality of the crescent and the maximization of marketability as the outer circumference surface of the mount (2a) can be manufactured in various round shapes.
