Description
- This is a Continuation-In-part patent application for applicant's former application Ser. No. 11/103,572, filed on Apr. 12, 2005.
- A conventional toilet generally includes a bowl and a tank in which water is received and a link mechanism is located in the tank so that when the user pivots a flush handle, the water in the tank enters and flushes the bowl via a valve seat which is normally sealed by a tank ball. The link mechanism includes a link which is directly connected with the flush handle and the tank ball can be lifted by the pivotal movement of the link. The valve seat is sealed again when water re-fills the tank again. There are several types of arrangements for the link and the flush handle. The angle between the link and the flush handle is varied in different areas. If the angle is not correctly set, the volume of the water e to flush the toilet might be affected. Therefore, the manufacturers have to manufacturer and assemble the link mechanism according to the requirements in different areas. This increases the cost of the manufacturers.

Besides, complicated machining processes are needed to make the desired shape of the parts. Obviously, the fabrication cost for the two link mechanisms of Berlovan (US 2005/0273919) and Chuang (U.S. Pat. No. 5,265,969) will be too high to be accepted by the customers.
- The present invention intends to provide an angle adjustable link mechanism which includes an adjustable assembly such that the angle of the link and the flush handle can be easily adjusted.
- The present invention relates to a link mechanism for toilets and the mechanism comprises a flush handle with a connection extension extending from a shaft thereof and an adjustable assembly has a first part and a second part which is rotatably connected to the first part. The connection extension is connected to the second part. A link has a first end connected to the first part and a second end of the link is connected to the tank ball. The position of the link can be set by rotating the second part relative to the first part.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

FIG. 1 is an exploded view to show the link mechanism of the present invention; -
FIG. 2 is a perspective of the link mechanism of the present invention; -
FIG. 3 is a cross sectional view to show the link mechanism of the present invention; -
FIG. 4 shows that the link is pivotable about the common shaft connecting the first and second part of the link mechanism of the present invention; -
FIG. 5 is an exploded view to show another embodiment of the link mechanism of the present invention, and -
FIG. 6 is a perspective of the link mechanism inFIG. 5 . - Referring to
FIGS. 1 to 3 , thelink mechanism 1 for toilets of the present invention comprises aflush handle 10 pivotably connected to a tank of the toilet (not shown) and a shaft extends through the wall of the tank and aconnection extension 11 extends from a shaft thereof. - An
adjustable assembly 22 is connected between theflush handle 10 and alink 21, and includes afirst part 221 and asecond part 222 which is rotatably connected to thefirst part 221. Thelink 21 includes afirst section 211 and asecond section 212 which is parallel to thefirst section 211. The first andsecond sections connection section 213 is connected between the first andsecond sections - The
first part 221 includes afirst connection member 2211 and a firstpivotable member 2212 which is connected to a side of thefirst connection member 2211. Thefirst connection member 2211 includes afirst slot 2213 in which a first end of thelink 21 is fixed therewith by extending apositioning member 30 through ahole 2214 defined in thefirst connection member 2211 and is connected with ahole 214 in thelink 21 in thefirst slot 2213. A second end of thelink 212 is connected to a tank ball (not shown) which seals a valve seat of the tank. - The
second part 222 includes asecond connection member 2221 and a secondpivotable member 2222 which is connected to a side of thesecond connection member 2221. Thesecond connection member 2221 includes asecond slot 2223 in which theconnection extension 11 is fixed therewith by extending another positioning member through ahole 2224 defined in thesecond connection member 2221 and contacting against theconnection extension 11. Acollar 2231 is mounted on a top of the secondpivotable member 2222 and thecommon axle 224 extends through thecollar 2231, the secondpivotable member 2222 and apassage 2215 in the firstpivotable member 2212 and is connected with anut 225. Atongue 2232 extends radially from thecollar 2231 and astud 2233 extends from an underside of thetongue 2232. Thestud 2233 is inserted in arecess 2217 defined in a top of thefirst connection member 2211. Thefirst connection member 2211 includes arack portion 2216 integrally formed on the side where the firstpivotable member 2212 is connected. Therack portion 2216 is formed axially in the side of thefirst connection member 2211 and the firstpivotable member 2212 is located beneath the rack portion. The secondpivotable member 2222 is a cylindrical member which includesteeth 2225 integrally defined in an outer periphery thereof so as to be directly engaged with therack portion 2216. Therefore, thefirst connection member 2211 is pivotable about thecommon axle 224 as shown inFIG. 4 to set the desired position of thelink 21. Theteeth 2225 of the secondpivotable member 2222 are located in the whole outer periphery of the cylindrical secondpivotable member 2222 so that the angular position between thefirst connection member 2211 and the secondpivotable member 2222 can be set as needed in almost every direction. The link mechanism can be used in different areas and meets requirements for different areas by adjusting the position of thelink 21. - Once the angular position between the first and
second connection members common axle 224 is secured by thenut 225 so that thefirst connection member 2211 and the secondpivotable member 2222 are set and do not rotate relative to each other. There is no extra element needed to set the relative position between the first andsecond connection members rack portion 2216 and theteeth 2225 is direct, strong and reliable. -
