Title:
HINGE BOLT HAVING BEARING EMBEDDED THEREIN
Document Type and Number:
WIPO Patent Application WO/2014/112778
Kind Code:
A1
Abstract:
The present invention relates to a hinge bolt having a bearing embedded therein. The hinge bolt has a circular ring formed at the upper portion thereof and a screw thread formed at the lower portion thereof, wherein the circular ring has a through hole formed therein. The hinge bolt further includes: a bushing forcedly fitted in the ring and having a through hole formed therein; and a rotational bearing disposed in the busing, being rotatable relative to the busing, and having a through hole formed therein. The rotational bearing rotatably embedded in the ring of the hinge bolt can rotate together with an object to be fixed, when the object coupled with the ring shakes due to an external impact. Therefore, the rotational bearing can safely compensate for the external impact to prevent the object from being broken or damaged by the impact, which allows the product to be versatile. Further, the hinge bolt having the bearing embedded therein is simple to manufacture and thus may be competitively priced.
