Abstract:
Provided is a hinge lock mechanism that reduces the cost and work load for production of a toilet or a toilet seat and a toilet seat cover. A hinge lock mechanism according to one embodiment is configured from a support column 16, a disk hook 15, and a second inner diameter part 20a2, 30a2. This hinge lock mechanism prevents a hinge device 10, 10' from slipping out of an attachment hole 20a, 30a into which a shaft part 14 thereof is inserted, the hinge device 10, 10'supporting a toilet seat and a toilet bowl in such a manner to allow these objects to be freely opened and closed and supporting a toilet seat cover and the toilet bowl in such a manner to allow these objects to be freely opened and closed. When the shaft part 14 is inserted into the attachment hole 20a, the shaft part 14 fits into a first inner diameter part 20a1 and the disk hook 15, which is provided at the leading end of the shaft part 14, is inserted into the second inner diameter part 20a2. At this time, because of the elasticity thereof, the disk hook 15 bends and elastically deforms to fit into the second inner diameter part 20a2. Consequently, the outer circumference of the disk hook is caught on the inner circumference of the second inner diameter part 20a2.
