As shown in Figure 1, by common frame type wall 3 and with the bathroom 1 that separates mutually adjacent room 2 in, according to present embodiment, can a water tank 4 be installed in the anterior interlayer 5 and the inside between the rear portion interlayer 6 of frame type wall 3, said frame type wall then has only the spacing of 70mm.Thereby a flush toilet 8 is installed on the floor in bathroom 1 with the anterior interlayer 5 merga pass one cascading water pipe 9 that joins and is connected with water tank 4.

Fig. 2 illustrates how by two mounting brackets 11 water tank 4 to be installed between a pair of adjacent pillar 10 in the mode of decomposition diagram.(agent number: disclose the full details of above-mentioned mounting structure 251313), the disclosure of this application book is quoted from this with as a reference the applicant's common unsettled Australian patent application book PM2333 number.

The internal construction of water tank 4 such as Fig. 3 are to shown in Figure 6, and as shown in Figure 4, water tank 4 has one and is essentially the free end that common float support arm 14, one bell floaters 15 hang on this support arm.When water tank was in the level that soon is full of, the position of described float support arm was shown in solid line among Fig. 4.And when water tank 4 to small part became empty, the position of described float support arm was then by shown in the dotted line.In one position, back, float support arm 14 is opened has the inlet valve 16 that is essentially common structure, and this valve makes water enter the inside of water tank 4 by the outlet 17 of this inlet valve under the total linear pressure of water pipe.

Be provided with a socket 19 in the bottom of water tank 4, in this socket with cascading water pipe 9(Fig. 1) be connected and closed by a cascading water valve, this cascading water valve is a cascading water pipe 20 and a round rubber joint ring 21.(agent number: comprised whole detailed the saving of above-mentioned cascading water pipe 20 work in the disclosure 223402), this content is quoted from this with as a reference at the applicant's common unsettled Australian patent application book No. 54908/94 (being PL7178 in the past).

One detachable float 23 slidably is installed on the cascading water pipe 20, this float can be just like the upper position shown in the figure and once slide between the portion position, in said lower position, detachable float 23 can abut in two on the retainer 24 of cascading water pipe 20 both sides extension.

Utilize a pair of lock bolt support arm 25 float 23 can be stuck in upper position place shown in Figure 4, in Fig. 4, only shown one of front in the paired lock bolt support arm 25.Each lock bolt support arm 25 includes an inclined-plane 26 towards recess 27, and recess 27 then can engage with the respective flanges 28 on the float 23.

Latch arm is propped up 25 plates 29 that send by a pair of one-tenth integral body and is interconnected.In addition, lock bolt support arm 25 can be pivotable by a pair of minor axis 30, and said minor axis then extends to sleeve pipe 31(Fig. 3 that cascading water pipe 20 is passed respectively) front and rear.Minor axis 30 is extending between arm and the rear wall before sleeve pipe 31 and the water tank 4.The opening 32 of lock bolt support arm 25 by a keyhole is stuck on the minor axis 30 and can be pivotable around this minor axis.

Two L shaped supporting members 35 are positioned at the top of cascading water pipe 20.All have a perforate 36(Fig. 3 and a Fig. 5 who connects on the upper level part of each supporting member 35).The lower end of supporting member 35 vertical components then ends at a compound minor axis 37.

Each minor axis 37 is all supporting a C shape cascading water starting bar 38 in the mode of pivot.As shown in Figure 5, these two cascading water starting bars 38 have a pair of

support arm

39 and 40 respectively.Should be noted that distance between the support arm 39 is larger than the distance between the support arm 40 that is within support arm 39

scopes.Support arm

39 and 40 all can be engaged in flange 41(Fig. 3 of reverse extension), the relative cascading water pipe 20 of this flange extends along direction from front to back.

Be extruded with a hollow elastic bellows 43 between the horizontal component of the middle part of each cascading water starting bar 38 and each L shaped supporting member 35, this bellows is made by rubber or other elastic artificial elastomeric material.Corresponding air conduit 44 leads to the into inside of each bellows 43, and this air conduit couples together cascading water switch on corresponding cascading water starting bar 38 and two with corresponding one in the air pump 45.As shown in Figure 6, the cascading water switch is installed on the access lid 46 with air pump 45, and this access lid 46 covers on the access hole on the anterior interlayer 5 of frame type wall 3.

As shown in Figure 4, the cascading water switch of pushing the right side is with air pump 45, can make air enter to put in accordingly air conduit 44 in the bellows 43.Thereby this just can make corresponding cascading water bar 38 be pivotable and lift support arm 39.Flange 41 is lifted in this athletic meeting, thereby has also lifted cascading water pipe 20, therefore can carry out the cascading water operation.

Because right side cascading water starting bar 39 is to promote lock bolt support arm 25 along strengthening lock bolt support arm 25 with the direction that engages between the flange 28, so detachable float 23 still is stuck on the upper position shown in Fig. 4 solid line.As a result, can carry out cascading water completely, and when the water that is no longer left water tank 4 when cascading water pipe 20 descended because of own wt with the buoyancy supporting, the cascading water activity will stop.Because pushing cascading water switch 45 is relative very short processes, so this moment, support arm 39 turned back to the position of the level of being essentially already.

If push left side cascading water switch 45 momently, so, thereby the cascading water bar 38 in left side will be pivotable and lifts support arm 40 and promote cascading water pipe 20.Simultaneously, left side cascading water starting bar 28 pivot motion as shown in Figure 4 can make lock bolt support arm 25 be pivotable again, thereby detachable float 23 can make cascading water pipe 20 move down with the decline degree of water in the water tank.Thereby stay when making in the water tank that detachable float 23 is run into retainer 24 as enough water, cascading water pipe 20 can descend in advance, thereby ends the cascading water process in advance, therefore only carries out " half cascading water ".

When water tank was full of once again, detachable float 23 can rise, and flange 28 can ride on the inclined-plane 26 and stick into recess 27 once more until this flange 28.Thereby this will make lock bolt support arm 25 reset detachable float 23 is clamped in upper position, until the next operation that carries out left side cascading water switch 45.

The

support arm

39,40 and the lock bolt support arm 25 that should be noted that cascading water starting bar 38 all can be pivotable in the plane of perpendicular, and these are essentially anterior interlayer 5 and rear portion interlayer 6 that vertical plane then is parallel to frame type wall 3.In addition, above-mentioned starting bar and lock bolt support arm can be around also therefore being pivotable along the axle that the water tank fore-and-aft direction extends perpendicular to aforementioned plane.By the parts of aforementioned rotor motion are set in this structure, can obtain to be enough to carry out the length of appropriate exercise and the strength that will produce, simultaneously, above-mentioned whole device is installed in the very little space that is had between anterior interlayer 5 and the rear portion interlayer 6.

Best, cascading water pipe 20 is a hollow, and it plays a bleed off pipe.But, be applied in the septic tank at some, a bleed off pipe 48 independently also can be set.This bleed off pipe 48 tilts, thereby can directly not receive the water that enters water tank by inlet valve 16.

One embodiment of the present of invention below only have been described, concerning the expert of present technique, can have made multiple improvement to it without departing from the present invention.
