Document Type and Number:
WIPO Patent Application WO/2014/058111
Kind Code:
A1
Abstract:
The present invention relates to an elbow assembly structure allowing for omnidirectional angular adjustment that is not limited in terms of installation applications or of various installation sites, but has a wide range of use with respect to a bent site, and includes: a body (10) that is provided in one of "+," "ㅜ," "Y," and "L" shapes and has an inner space formed to be hollow; connection holes (20) that are formed to respectively extend from the body to sites that are independent in four directions and have inner portions thereof that communicate with the hollow body; and a number of connection members (30) that are provided in a symmetrical fan shape so as to form a curved path, and are fixedly coupled with each other in a sequential manner at respective end portions of the connection holes, and allow the curvature range of an area extending from the connection holes to vary. A lead-in projecting portion (35) is formed in an extending manner on one side of the connection member (30) so as to be introduced and interposed in the connection hole (20) or in an adjacent connection member, and "I" shaped inserting pieces (36) are arranged at regular intervals on the lead-in projecting portion. One or more "ㅌ" shaped fixing pieces (37 and 21) are formed in a projecting manner on the other side of the connection member and in the connection hole, the fixing piece being overlapped with the inserting piece (36) of the adjacent connection member through unidirectional rotation and being coupled in an inserted manner, so that a number of the connection members can be closely coupled with each other through mutual restriction of each of the inserting pieces and fixing pieces.
