Definitions

  • the present invention relates to an arrangement in a drainpipe comprising a funnel which, with an outlet portion, is connected to a lower portion of the drainpipe and in which an upper portion of the drainpipe discharges, the funnel being provided with a grid and a portion extending laterally outside the upper portion of the drainpipe.
  • the prior art arrangement provides no possibility for drawing-off the rainwater so that this can be collected for use on a later occasion.
  • the present invention has for its object to devise an arrangement of the type mentioned by way of introduction, the arrangement being further designed in such a manner as to permit simple collecting of rainwater.
  • the invention further relates to an arrangement which is simple and economical to manufacture and which may be expected to have a long service life.
  • the arrangement intimated by way of introduction is characterized in that the outlet portion or a portion of the arrangement disposed over the outlet portion is provideed with a shut-off valve; and that an outlet opening for rainwater is disposed above the level of the shut-off valve.
  • a suitable embodiment of the present invention is further characterized in that the shut-off valve is located beneath the grid.
  • shut-off valve is also disposed to be well protected from the effects of foreign matter by employment of the above-disclosed positioning.
  • the preferred embodiment is further also suitably characterized in that the grid is disposed to be accessible via the laterally projecting portion of the funnel.
  • Fig. 1 shows a vertical section through the arrangement according to the present invention, in a setting for drawing off rainwater
  • Fig. 2 is a section corresponding to the section of Fig. 1 , the arrangement according to the present invention having, however, been switched for normal operation.
  • the arrangement according to the present invention has an outlet portion 1 which consists of a substantially cylindrical pipe at whose upper end a circumferential shoulder 2 is disposed.
  • the outlet portion 1 may be passed down into an upper end portion of the lower portion of a drainpipe 3 which leads to a surface water drain.
  • connection between the outlet portion and the lower portion of the drainpipe 3 need not be of the type shown on the Drawing, but may be effected in any normal manner whatever which is acceptable for joining pipes.
  • An upper portion 4 of a drainpipe discharges at the upper end of the arrangement according to the present invention, and the arrow 5 intimates the flow direction of rainwater resulting from precipitation.
  • the arrangement according to the present invention is designed in such a manner that the upper and lower portions of the drainpipe, 4 and 3, respectively, are preferably coaxial with one another. Furthermore, the arrangement according to the present invention is provided with alignment members (not shown) which hold the upper portion 4 of the drainpipe in the correct position in relation to the arrangement according to the present invention and which also fix or at least support the upper portion 4 in the vertical direction as well.
  • That part of the arrangement according to the present invention which is located between the two drainpipe portions 3 and 4 may be described as a housing 6 whose shape at least partly corresponds to that of the cylinder.
  • the housing has a rear wall 7 which is approximately semi-cylindrical and which extends up to a diametric plane to the drainpipe which is substantially at right angles to the plane of the paper in Fig. 1.
  • the rear wall then merges into walls which are substantially parallel with one another and which, in a direction to the right in the Figures, merge into a front wall 8 which forms an upwardly open funnel 9.
  • this upwardly open funnel is generally oval in configuration and has, at least at the rear wall 7, a wall portion which is approximately semi-cylindrical and which connects about the lower discharge portion of the upper portion 4 of the drainpipe.
  • the configuration of the front portion of the upwardly open funnel 9 is immaterial according to the present invention, as long as its size is 5 sufficient to allow access with one hand to the area interiorly within the housing 6 between the upper and lower portions of the drainpipe 4 and 3, respectively.
  • a grid or mesh 10 which is I 0 shown on the Drawing by broken lines.
  • the grid may be substantially planar and of one-piece manufacture with the housing 6 and the remainder of the arrangement according to the present invention, but can also be loose and dismountable for simple cleaning.
  • the grid 10 slopes downwardly from the rear wall 7 and connects at its outer, lower end to the bottom wall of the 1 5 funnel 9. A greater grid area will hereby be obtained, despite the compact outer dimensions.
  • this shut-off valve which, in the closed position, blocks the outlet from the arrangement according to the present invention.
  • this shut-off valve consists of a rotary plate 11 which is rotatably secured in the wall of the outlet portion 1 by means of a rotary shaft 12.
  • This rotary shaft is suitably horizontal and runs along one diameter of the outlet portion 1.
  • the plate 11 is suitably circular in shape in order, with its periphery, to connect to the substantially cylindrically shaped outlet portion 1 and seal against the inner defining surface thereof.
  • the peripheral portion of the plate may be provided with a lip seal which is produced from an at least partly flexible and deformable material which can absorb tolerances and configurational discrepancies in both the plate and the outlet portion.
  • the plate 11 may be floatingly secured in the pivot shaft 12 so that it can, to some degree, move transversely of the outlet portion and thereby adapt to the inner defining surface of the outlet portion 1.
  • the surface cooperating with the periphery of the plate 11 can be provided with beads, projections or the like so that a snap lock is formed.
  • the arrangement according to the present invention is provided with an outlet opening 13 for rainwater. This implies that when the plate 12 is in the position illustrated in Fig. 1 (and hence substantially seals against the inner defining surface of the outlet portion 1 ), water will gather in the upwardly open funnel 9 and also in the housing 6 so that thereby water departs through the outlet opening 13.
  • the upwardly open funnel 9 should be relatively deep, at least one diameter of the drainpipe but preferably more so as thereby to impart sufficient pressure elevation to the water which is collected in the funnel in order to ensure departure of the water.
  • a deep funnel also reduces the risk of splashing. It is also possible to employ, on the upper side of the funnel 9 and around the upper portion 4 of the drainpipe, a sealing lid, with the result that rainwater can rise in the upper portion 4 of the drainpipe and thereby form a relatively high liquid column which imparts a substantially high pressure to the water departing through the outlet opening 13.
  • Fig. 2 shows the arrangement according to the present invention in a position in which the shut-off valve is open, and it will be apparent from the
  • the plate 11 or its pivot shaft 12 is connected to an operating arm 14 which supports a closure member 15 in the form of a conical or spherical disk or plug which, in the open position of the plate 11 , is located accommodated in a mouth portion 16 of that pipe 17 which forms the outlet opening 13, the mouth portion facing towards the funnel 9.
  • the design of the closure member 15 and the mouth portion 16 may suitably be at least partly complementary so that sealing surfaces are thereby created.
  • the closure member 15 is accommodated in the mouth portion 16 and seals this so that no water can depart through the outlet opening 13. Furthermore, any possible foreign matter accompanying the rainwater will hereby be prevented from access to the conduit which is connected to the outlet opening 13.
  • the operating arm 14 extends through the grid 10, more precisely through a slot-shaped narrow aperture through the grid.
  • the operating arm 14 and the closure member 15 are accessible for operating the plate 11 through the upwardly open funnel 9 in the same manner as the grid 10 is accessible for cleaning.
  • the above-described embodiment is advantageous as a result of its simple manufacture and operation. However, there is a minor risk that foreign matter accompanying the rainwater may possibly choke the outlet opening 13 when rainwater is to be collected. Consequently, it is assumed in one alternative embodiment according to the present invention that the outlet opening 13 is placed beneath the grid 10 so that thereby the protective function of the grid will also operate for that water which is drawn off via the outlet opening 13.
  • a counterpart to the pipe 17 may suitably be placed on the rear wall 7 of the housing 6 in the region slightly above the plate 11 in the closed position thereof.
  • the plate is provided with an operating arm for its pivotal movement, but in this embodiment, the pivoting takes place in the opposite direction between the open and closed position of the shut-off valve. In this embodiment, that arm which connects the plate 11 and the closure member 15 may be disposed entirely beneath the grid 10.
  • a handle which is disposed exteriorly on the outlet portion 1 and is secured on the shaft 12.
  • the plate covering the grid is pivoted about a horizontal shaft to a position where the grid is freely exposed upwardly.
  • the flap can be approximately vertical but can also be pivoted out at least partly so as to cover the lower defining wall in the funnel 9, so that thereby the outlet opening 13 is screened off from foreign matter.
  • a grid may be provided above the mouth of the pipe 17 so that foreign matter is prevented from penetrating.
  • the closure member 15 is provided with a number of projections which, in the closed position, extend down into apertures in the grid and seal them.
