Toilet seat apparatus

Abstract

A toilet seat apparatus includes a base portion adapted to be fixed on a toilet bowl, a main body portion detachably mounted on the base portion, a toilet seat rotatably supported by the main body portion, a guide groove formed at the base portion and extending in a backward and forward direction of the toilet bowl and having an opening portion at a front side thereof, and a pin provided at the main body portion, the pin being inserted into the guide groove for allowing the main body portion to slide relative to the base portion, rise from the base portion, and to detach from the base portion.

1 . A toilet seat apparatus comprising: 
 a base portion adapted to be fixed on a toilet bowl;    a main body portion detachably mounted on the base portion;    a toilet seat rotatably supported by the main body portion;    a guide groove formed at the base portion and extending in a backward and forward direction of the toilet bowl and having an opening portion at a front side thereof; and    a pin provided at the main body portion, the pin being inserted into the guide groove for allowing the main body portion to slide relative to the base portion, rise from the base portion, and to detach from the base portion.    
   
   
       2 . The toilet seat apparatus according to  claim 1 , wherein the pin is slidably and rotatably supported in the guide groove, and the main body portion is slidable along the guide groove with the pin and is rotatable with the pin relative to the base portion, and wherein the main body portion is detachable with the pin from the opening portion of the guide groove.  
   
   
       3 . The toilet seat apparatus according to  claim 1 , wherein the pin is inserted into the guide groove from the opening portion upon assembling the main body portion relative to the base portion.  
   
   
       4 . The toilet seat apparatus according to  claim 1 , wherein the toilet seat apparatus further comprises opening and closing means for allowing attaching and detaching operations of the main body portion relative to the base portion by opening the opening portion of the guide groove, and for restricting the attaching and detaching operations of the main body portion relative to the base portion by closing the opening portion of the guide groove.  
   
   
       5 . The toilet seat apparatus according to  claim 3 , wherein the opening and closing means includes a movable plate and a biasing means for biasing the movable plate to close the opening portion of the guide groove for restricting the attaching and detaching operations of the main body portion.  
   
   
       6 . The toilet seat apparatus according to  claim 1 , wherein the main body portion includes a washing mechanism therein.  
   
   
       7 . The toilet seat apparatus according to  claim 1 , wherein the toilet seat includes a heated toilet seat.  
   
   
       8 . The toilet seat apparatus according to  claim 1 , wherein the pin includes a substantially elliptical cross section, a major axis of which is wider than a width of the guide groove.  
   
   
       9 . The toilet seat apparatus according to  claim 1 , wherein the toilet seat apparatus further comprises a toilet cover rotatably supported by the main body portion.  
   
   
       10 . A method for assembling a toilet seat apparatus, the method comprising the steps of: 
 arranging a main body portion at a front side of an upper surface of a toilet bowl;    pushing the main body portion rearward of a base portion until a pin reaches a guide groove through an opening portion of the guide groove;    pushing the main body portion rearward of the base portion so that the pin slides along the guide groove to finally reach a closing portion of the guide groove; and    fixing the main body portion to the base portion.    
   
   
       11 . The method for assembling the toilet seat apparatus according to  claim 9 , the method further comprises the steps of fixing the base portion to the toilet bowl and rotatably assembling the toilet seat to the main body portion before arranging the main body portion at the front side of the upper surface of the toilet bowl.
