Definitions

  • the invention relates to a shut-off device for a street gully, with an insert with an inlet opening and with a closure means provided on the insert.
  • shut-off devices are known for example from DE-PS 33 41 899 and DE-GM 89 07 817.9.
  • the closure means is designed as a rotary flap and is arranged essentially within the insert and held in the center by a pivot axis. The rotary flap is thereby pivoted with its two halves around the pivot axis when it is to be opened or closed. It is pivoted into the closed position so that it lies sealingly with its peripheral edge on the inside of the insert.
  • shut-off devices are widely used and work essentially satisfactorily, there is nevertheless a need for an improvement of the shut-off device, in particular for a reduction in the design and simplification of the construction.
  • the closing elements preferably consist of flaps.
  • the pivot axes of the closing elements are arranged in the region of the outlet opening of the insert and, in their closed position, the closing elements lie substantially flat and sealingly against the section or edge of the insert surrounding the outlet opening.
  • the pivot axes of the closing elements can run essentially parallel and / or can be arranged essentially horizontally.
  • each closing element is laterally offset from the center thereof and in particular are arranged on one side edge section.
  • it is achieved in a particularly simple constructive manner that the closing elements in their open position protrude essentially only in the direction away from the inlet opening of the inlet into the street gully.
  • the closing elements are essentially horizontal in their closed position and are held by a closing device in such a way that after loosening the closing device they only open due to the influence of gravity.
  • This arrangement is particularly advantageous in that no further aids are required to open the closure means, since the pivoting of the closing elements is simply triggered by the influence of gravity.
  • two locking elements are provided, the pivot axes of both locking elements coinciding to form a common pivot axis which is arranged essentially centrally on the insert.
  • the two closing elements can also be arranged symmetrically to the common pivot axis and can be of identical design.
  • the insert has the shape of a cylinder, the common pivot axis runs at right angles to the cylinder axis of use and the closing elements are formed from two substantially semicircular and disc-shaped flaps which are suspended with their straight side edge on the pivot axis.
  • a web can be attached to the insert adjacent to the common pivot axis, on which the two closing elements are in their closed position with their remaining part in sealing contact. With the aid of such a web, an effective sealing connection between the two closing elements is produced in a particularly simple manner.
  • the web can preferably consist of a substantially straight V or U profile open to the pivot axis and the closing elements with two spaced-apart side legs which are arranged on both sides of the pivot axis and against which the closing elements rest in their closed position.
  • the edges of the two side legs of the web and the edge or section of the insert surrounding the outlet opening can lie in a common plane, which also forms the closing plane of the two closing elements.
  • a further preferred embodiment of the invention is characterized in that a fixed lever arm is attached to each locking element, which extends beyond the pivot axis, and the locking device has a rotatable locking bolt with two essentially radially arranged side arms, which when the locking bolt rotates by one first into a second rotational position in contact with the lever arms of the closing elements in their open position and apply a pivoting movement to the lever arms, as a result of which the closing elements move into their closed position Position are pivoted, and overlap the lever arms in the second rotational position such that they form an abutment for the lever arms and thus prevent pivoting of the closing elements from their closed position.
  • the two lever arms are expediently arranged laterally offset with respect to the pivot axis of the two locking elements on both sides of the axis of rotation of the locking bolt.
  • the axis of rotation of the locking bolt should intersect the pivot axis of the locking elements essentially at right angles and each lever arm should have a first section attached at right angles to the associated locking element and a second section that adjoins it at right angles, essentially parallel to the locking element and extending beyond the pivot axis Have section with which a lever arm of the locking bolt can be brought into contact.
  • shut-off device Essential components of the exemplary embodiment of a shut-off device described below are the base ring shown in FIG. 1 and two flaps, of which flap 20 is shown by way of example in FIG. Further important components of the shut-off device can be seen in FIGS. 3 to 5, in which the embodiment of the shut-off device described below is shown in the assembled state.
  • the base ring 2 shown in Figure 1 has a cylindrical shape and forms a frame or insert of the shut-off device.
  • the cylindrical base ring 2 is open at its two end faces, so that an inlet opening 4 is formed on one side and an outlet opening 6 is formed on the opposite side.
  • the base ring 2 is usually installed in the horizontal position shown in FIG. 1, in which the inlet opening 4 is located on the top side and the outlet opening 6 is located on the bottom side. In this installation position, the base ring 2 is also shown in the following FIGS. 3 to 5.
  • the base ring 2 is provided on the side of the inlet opening 4, that is to say on the top side, with a radially projecting, flange-like edge 7, which acts as a bearing serves for the base ring 2 in a street gully.
  • the base ring 2 is subdivided by a web 8 running through its center, which is fastened with its two ends to the inner wall of the base ring 2.
  • the web 8 consists of a straight, U-shaped profile open to the outlet opening 6 with two parallel side legs 9, 10 and a central part 12 connecting them.
  • the web 8 intersects the cylinder axis of the base ring 2 at a right angle, and the two side legs 9, 10 run symmetrically to the diameter of the base ring 2.
  • the free end faces 9a and 10a of the two side legs 9 and 10 of the web 8 lie together with the end face 2a of the outlet opening 6 Base ring 2 in a common plane that extends at right angles to the cylinder axis of the base ring 2.
  • a bore 14 is also formed, which is arranged coaxially to the cylinder axis of the base ring 2.
  • a retaining eye 16 is also provided in each case.
  • the two retaining eyes 16 are attached to the end face 2a surrounding the outlet opening 6, that is to say according to FIG. 1 on the underside, of the base ring 2 and lie diametrically opposite one another.
  • the retaining lugs 16 are each provided with a bore 18, the two bores 18 being aligned with one another and their common axis intersecting the cylinder axis of the base ring 2 and extending beyond or below the outlet opening 6.
  • the distance between the two tabs 26 and the distance between the one tab 26 and the outer end of the straight edge 24 at which it meets the semicircular edge 22 each correspond at least approximately to the length of a tab 26.
  • a lever arm 30 is attached to one surface of the flap 20, which, as can be seen from FIGS. 3 to 5, forms the side facing the base ring 2 in the closed position.
  • This lever arm 30 has a first section 30a, which is fastened at right angles to the flap 20, a second section 30b adjoining this first section 30a, which extends parallel to the flap 20 and at right angles to the common axis of the bores 28 beyond it , and a hook-shaped third section 30c adjoining the second section 30b, which is directed away at right angles from a plane spanned by the flap 20.
  • the function of the lever arm is explained in more detail below with reference to FIGS. 3 and 4.
  • FIGS. 3 to 5 now show the exemplary embodiment of a shut-off device described here in the completely assembled state.
  • Two identical flaps 20 and 21 are provided as the locking device, of which flap 20 has been described previously with reference to FIG. 2.
  • Both semicircular flaps are pivotally arranged at the outlet opening 6 of the base ring 2 such that they face each other with their straight edge 24 and are mounted together on a shaft 32 which is inserted with its ends into the bores 18 of the retaining eyes 16.
  • the straight edges 24 of the flaps 20, 21 lie opposite each other so that the tabs 26 interlock and the shaft 32 is inserted through the bores 28 of all tabs 26. Accordingly, the central axis of the cylindrical shaft 32 coincides with the common central axis of the bores 28 and forms the pivot axis 29 for both flaps 20 and 21.
  • both semicircular flaps 20 and 21 lie in a common plane and form a disc-shaped and circular closure.
  • the two flaps 20 and 21 each lie flat with the section adjoining the semicircular edge 22 on the end face 2a of the base ring 2 surrounding the outlet opening 6 and flat with the section adjacent to the straight edge 24 on the free end faces 9a and 10a of the web 8 , whereby an effective seal between the flaps 20, 21 on the one hand and the base ring 2 and the web 8 on the other hand and thus a closure of the base ring 2 is achieved.
  • a locking bolt 34 is rotatably mounted on the web 8.
  • the locking bolt 34 is inserted through the bore 14 in the central part 12 of the web 8 (see FIG. 1) and secured on the side facing the outlet opening 6 of the base ring 2 with a cylindrical notch pin 36.
  • the locking bolt 34 is arranged so that its axis of rotation coaxially coincides with the cylinder axis of the base ring 2 and the pivot axis 29 of the flaps 20, 21 intersects at right angles.
  • a square head 38 is provided, which extends beyond the inlet opening 4 of the base ring 2.
  • a suitable tool for rotating the locking bolt 34 can be plugged onto the square head 38.
  • two side arms 40, 41 are attached which are designed as straight pins and whose central axes coincide to form a common axis which intersects the axis of rotation of the locking bolt 34 at right angles.
  • the side arms 40, 41 cooperate with the lever arms 30 attached to the flaps 20, 21 in order to convert the rotary movement of the locking bolt 34 into a pivoting movement for closing the flaps 20, 21.
  • the lever arms 30, the locking bolt 34 and the side arms 40, 41 thus have the function of a locking device.
  • each lever arm 30 extends at right angles to the pivot axis 29 beyond it.
  • each lever arm 30 is laterally offset from a plane spanned by the axis of rotation of the locking bolt 34 and extending at right angles to the pivot axis 29 of the flaps 20, 21 at such a distance that during a pivoting movement of the associated flap 20 or 21 an obstruction with the locking bolt 34 is excluded and the lever arm 30 can thus move freely.
  • This arrangement results from the fact that the lever arm 30 in a sufficient Distance to the diameter intersecting the straight side edge 24 at right angles and the second section 30b runs parallel at that distance to this diameter, as can be seen in FIG.
  • the two lever arms 30 of the two flaps 20, 21 are accordingly arranged on different sides of the above-mentioned plane and thus of the locking bolt 34.
  • the locking bolt 34 assumes a first rotational position in which the side arms 40, 41 are essentially at right angles to the pivot axis 29, and the two lever arms 30 of the flaps 20 protrude , 21 with their second sections 30b up to the height of the side arms 40, 41, so that the hook-shaped third sections 30c of the lever arms 30 are located a little above the side arms 40, 41.
  • FIG. 4 shows, in the closed position of the flaps 20, 21, the second sections 30b of the lever arms 30 lie parallel to one another in a plane extending at right angles to the cylinder axis of the insert 2 or the axis of rotation of the locking bolt 34.
  • the base ring 2 shown in Figures 3 to 5
  • they are in a horizontal position. They are overlapped by the side arms 40, 41 and continue to abut against them, although excessive pressure from the side arms 40, 41 need not be exerted on the lever arms 30.
  • a lock against excessive closing is not necessary since the locking bolt 34 no longer has to develop any significant closing force in its second rotational position shown in FIG.
  • the position of the side arms 40, 41 on the locking bolt 34 and the dimensions of the lever arm 30 must of course be coordinated accordingly; ie the distances between the side arms 40, 41 and the outside of the second section 30b of the lever arm 30 facing away from the flap from the pivot axis 29 must correspond to one another.
  • sufficient space must be left between the side arms 40, 41 and the web 8 so that the lever arm 30 with its second section 30b can lie in between, as FIG. 4a clearly shows.
  • the location and length of the first section 30a and the thickness of the second section 30b of the lever arms 30 and / or the web 8 can be dimensioned such that the pivoting movement of the lever arms 30 is not hindered by the web 8.
  • FIG. 5 shows how the shut-off device described above is installed in a street gully 42.
  • the frame 44 of the street gully 42 has an inwardly projecting edge on which the base ring 2 rests with its flange-like edge 7 which projects outwards.
