  • Patent number: 4173802
    Abstract: A hinge arrangement for detachably connecting a lavatory seat and cover to a lavatory stool employs a holder secured to the stool and a pair of hinge pins each having a pair of brackets secured thereto, one pair for attachment to the seat and one to the cover. The holder has two pairs of resilient C-shaped clips, each pair being such that one of the hinge pins can be pushed into and pulled out of it. The axial spacing between the clips of each pair equals the sum of the axial length of the bearing portion of the pair of brackets retained by that pair of clips, to provide axial positioning of the brackets.
