Description
- This application is based on and claims priority under 35 U.S.C. § 119 to Japanese Patent Application 2005-093371, filed on Mar. 29, 2005, the entire content of which is incorporated herein by reference.
- This invention relates to a toilet seat apparatus, and more particularly to a toilet seat apparatus which is detachable from a toilet bowl.
- Conventionally, a toilet seat apparatus practically used is provided with a washing mechanism for spouting warm water for washing, and a heating mechanism for heating a toilet seat. Such conventional toilet seat apparatus generally includes a base portion provided at a rear side of an upper surface of a toilet bowl, a main body portion supported by the base portion, a toilet seat for seating, and a toilet cover for opening and closing an upper surface of the toilet bowl. The toilet seat and the toilet cover are rotatably supported at the main body portion. The toilet seat apparatus further includes a washing nozzle, a warm water tank, a heater, and a keep-warm portion if need arises. Recently, a toilet seat apparatus with a movable main body portion has been introduced. The movable main body portion of this type is movable for making a space between a toilet bowl main body and the main body portion of the toilet seat apparatus so that the cleaning can be easily made. One of the known washing toilet seat apparatuses including a lifting mechanism is disclosed in JPH9-316976A. More particularly, the disclosed toilet seat apparatus includes the lifting mechanism for lifting the main body portion in an outside direction, a lateral direction, a rear direction, or an upper direction of the toilet bowl. By means of the lifting mechanism, the quite heavy main body portion can be moved without difficulty and yet in a safe manner.
- With the configuration of the toilet seat apparatus disclosed in JPH9-316976A, the main body portion cannot be readily detached considering any possible falling of the main body portion and for improvement of safety. However, the main body portion may necessarily be detached for checking inside thereof or for draining water from the tank in order to prevent freeze in a condition where the toilet seat apparatus is not used for a long period of time. Under such circumstances, entire washing toilet seat is detached by loosening a fixing bolt and a nut, by which the base portion is fixed to the toilet bowl main body. Because detachment and reattachment of the main body portion may necessarily be performed within a limited space located below a lower tank at a rear side of the toilet bowl, the detachment and reattachment of the main body portion may occasionally be difficult and may require careful attention.
- A need thus exists for a toilet seat apparatus, which can detach a movable main body portion together with a toilet seat and a toilet cover from a base portion without difficulty in a safe manner.
- According to an aspect of the present invention, 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.
- According to an another aspect of the present invention, a method for assembling a toilet seat apparatus, the method includes the steps of arranging the main body portion at a front side of the upper surface of the toilet bowl, pushing the main body portion rearward of the base portion until the pin reaches the guide groove through the 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.
- The foregoing and additional features and characteristics of the present invention will become more apparent from the following detailed description considered with reference to the accompanying drawings, wherein:

- With the configuration of the toilet seat apparatus according to the embodiments of the present invention, the base portion is provided at the rear side of the upper surface of the toilet bowl for slidably and swingably supporting the main body portion. The base portion is fixed to the rear side of the upper surface of the toilet bowl by means of the fixing member such as the bolt, or the like. The base portion is formed with the guide groove arranged in the backward and forward direction of the toilet bowl for supporting the main body portion.
- With the configuration of the toilet seat apparatus according to the embodiments of the present invention, two guide grooves are arranged at both sides of the base portion, respectively. However, the present invention is not limited thereto. Alternatively, or in addition, a single guide groove may be arranged at the upper surface of the base portion. Further, alternatively, or in addition, more than two guide grooves may be arranged at the base portion. The guide groove may include a generally rectangular cross section. Alternatively, or in addition, an interior of the guide groove may be configured to be wider than an inlet portion of the guide groove for preventing the main body portion from being detached from the base portion. Because a length of the guide groove in the backward and forward direction is mostly equivalent to a stroke of the main body portion slidable along the guide groove, the present invention is applicable as long as the length of the guide groove is defined in view of convenience in cleaning. Further, the guide groove includes the opening portion at the front side thereof and the guide groove is thereby opened outward.
- The main body portion may include the washing mechanism therein. Further, the toilet seat may be the heated toilet seat. With the configuration of the toilet seat apparatus according to the embodiments of the present invention, the main body portion, which is a major member of the toilet seat apparatus, rotatably supports the toilet seat and the toilet cover. The toilet seat apparatus may be provided with the washing mechanism such as a washing nozzle, a warm water tank, or the like.

First, the base portion is fixed to the rear side of the upper surface of the toilet bowl by means of the fixing member. Next, the main body portion is arranged on the toilet bowl in such a manner that the pin is positioned in front of the opening portion located at a front side of the base portion. Then, the biasing means is released to open the opening portion, and the main body portion is pushed to move rearward. On this occasion, the pin is inserted into the guide groove through the opening portion, and the main body portion is thereby supported by the base portion. Then, the main body portion is further pushed rearward so that the pin slides along the guide groove to reach a rear side of the guide groove. On this occasion, the toilet seat apparatus becomes available by fixing the main body portion by means of the engaging mechanism.
- At the time of cleaning, the upper surface of the toilet bowl can be opened in order by sliding the main body portion by removing the engaging mechanism, by lifting the main body portion by swinging it at the given sliding position, and by rotating the toilet seat and the toilet cover. Further, because the opening portion is closed by mean of the biasing means, the main body portion is not detached from the base portion at the time of cleaning.
- According to the embodiments of the present invention, the main body portion of the toilet seat apparatus is detached from the base portion in accordance with the following order. First, the engaging mechanism is removed, and then the main body portion is pulled forward by sliding the pin along the guide groove. Next, the biasing means is released to open the opening portion, and the main body portion is further pulled and detached from the base portion by pulling the pin out of the opening portion. Accordingly, the attaching and detaching operations of the main body portion can be performed in a safe manner without lifting or raising the main body portion during the operation in a condition where the base portion is fixed at the toilet bowl.
