Definitions

  • the present invention relates to a barrier for installation in a sewage pipe, the barrier preventing rats or other vermin from entering a sewage pipe system, said barrier comprising at least two shutters pivotally mounted on the barrier on a first and a second hinge, and a locking mechanism preventing vermin from entering the sewage pipe system.
  • the invention may be particularly, but not exclusively, advantageous for obtaining a barrier, which may be effective in preventing vermin from passing the barrier in at least one direction, since a locking system with at least two parts are mounted on the barrier, the locking mechanism preventing vermin from being able to open the shutters from the upstream direction, the locking mechanism being shaped and mounted on the barrier so that no vermin would not be able to unlock the locking mechanism and thereby would not be able to enter the pipe system, despite the tendency of vermin to tries assiduously to pass the barriers.
  • the invention may be particularly, but not exclusively, advantageous for obtaining a barrier, which may be more effective in preventing vermin from passing the barrier in at least one direction, since the parts of the locking mechanism may be exchangeable.
  • the parts of the locking mechanism are possibly existing in a variety of different shapes and dimensions, thereby possibly be exactly suitable for the specific sewage pipe system it is to be installed in.
  • the invention may be particularly, but not exclusively, advantageous for obtaining a barrier, which may be more reliable, such as not being blocked by organic solid matter and other solid matter in, e.g., a sewage flow, since the shutters and the locking mechanism in the barrier makes a sewage flow in a downstream direction possible, furthermore an edge of the first shutter is possibly smoother than a corresponding edge of the second shutter, whereby the first shutter therefore may be less likely to attract organic solid matter and other solid matter in, e.g., a sewage flow, since such solid matter is less likely to get attached to, such as stick to, the smoother edge.
  • the invention may be particularly, but not exclusively, advantageous for obtaining a barrier, which may be effective in preventing vermin from passing the barrier in at least one direction, since the barrier makes it possible to alter the orientation of the at least first shutter between a first orientation and a second orientation in the barrier, i.e. positioning the shutter in the one direction or the other direction in the barrier, results in the one and same barrier being applicable for sewage systems, nondependent on whether the vermin may enter one way or the opposite way according to a longitudinal extension of the barrier.
  • the at least first shutter may always be positioned so that the vermin is prevented from entering without the need for different barriers with differently positioned shutters, one barrier for each way of possible entering of the vermin.
  • a more reliable and efficient barrier may be achieved by having a very reliable and durable locking mechanism as a part of the barrier.
  • the locking mechanism making sure, that no vermin can pass the barrier in an upstream direction, simultaneously the barrier and the locking mechanism still allowing solid organic waste and other solid material to pass in the downstream direction.
  • the barrier with the locking mechanism thereby enable both effective blocking of rats and other vermin, and enabling a reduction of risk of blocking of the barrier.
  • a 'barrier' may be understood as is common in the art and described in, e.g., European patent application EP 1 826 326 A1 and/or EP 2 113 615 B1 .
  • the barrier may be installed as described in, e.g., European patent application EP 1 826 326 A1 which is hereby incorporated in their entirety.
  • the barrier may be positioned at least partially within a sewage pipe, such as partially within a sewage pipe and partially outside of a sewage pipe, such as partially in a well adjacent the sewage pipe, such as a completely inside a sewage pipe.
  • the barrier may be located in a downstream sewage pipe to let rodents escape from a well and further away from housings.
  • the barrier may also be used in an upstream sewage pipe so as to allow rats or other rodents to escape into a well and away from the upstream sewage pipe leading to, e.g. a housing.
  • 'vermin' may be understood as any animal similar sized with a rat and that lives or moves within sewage pipes systems. This may e.g. being any rodent or a like.
  • a 'pipe' may in general be understood to be any pipe, and in particular a sewage pipe, such as pipes for leading a sewage flow, such as any one of domestic sanitary, commercial, industrial, agricultural sewage flow and surface runoff.
  • the pipes usually have a circular cross-sectional profile, but other profiles, e.g. elliptic cross-sectional profile, or with vertical sides and rounded bottom, are possible within the context of the present invention as the skilled person will understand.
  • the barrier may prevent vermin from passing the barrier in at least one direction, such as the second direction, such as an upstream direction. It may further be understood, that the barrier may not block rats or vermin from passing the barrier in the opposite direction, such as in the first direction, such as a downstream direction.
  • the barrier may be installed in a pipe so as to allow a flow of liquid in a first direction, such as a downstream direction, and so as to block rats or other vermin from passing the barrier in a second direction, such as an upstream direction. It may be understood, that the barrier may not necessarily block passage of rats or other vermin in a downstream direction.
  • 'first direction' is understood a direction of flow of sewage in the sewage pipe, such as a downstream direction. While a pipe in itself may be symmetrical and as such not have any specific flow direction, it is in general understood, that a pipe, such as a sewage pipe, has a primary direction of flow, such as a direction of flow. The direction of flow is the direction in which liquid typically flow through the pipe, such as due to gravity and/or pressure differences.
  • 'first direction' is understood at direction being parallel with a longitudinal direction of the sewage pipe in a direction being similar to a direction in which flow of sewage is allowed by the barrier, such as a downstream direction.
  • 'second direction' is understood a direction in which rats or vermin are blocked.
  • the second direction may be the upstream direction.
  • 'second direction' is understood a direction being parallel with a longitudinal direction of the sewage pipe in a direction being similar to a direction in which rats or other vermin are being prevented from passing the barrier, where the second direction is opposite to the first direction, such as the second direction being an upstream direction.
  • 'upstream direction' of a pipe is understood a direction opposite the flow direction in the pipe.
  • 'downstream direction' of a pipe is understood a direction of flow of liquid in the pipe.
  • a support structure' is understood a structural part of the barrier in from which the shutters may be pivotally suspended.
  • the support structure may be structurally fixed to the sewage pipe, such as fixed via other structural elements in the barrier, such as fixed in an upper portion of the sewage pipe (with respect to gravity).
  • a 'shutter' may be understood as is common in the art, such as described in, e.g., European patent application EP 1 826 326 A1 and/or EP 2 113 615 B1 .
  • a shutter may thus denote a structural element, such as a plate or a net or a set of bars, which may be pivotally suspended so as to facilitate barring an aperture in a first angular position and not barring the aperture in a second angular position.
  • first shutter' and 'second shutter' may be understood shutters which are placed relative to each other, so that in case the barrier is installed in a pipe so as to allow a flow of liquid in a first direction, such as a downstream direction, and so as to block rats or other vermin from passing the barrier in a second direction, such as an upstream direction, the first shutter is placed upstream relative to the second shutter.
  • the first shutter is the first shutter, which the water passes when flowing through the pipe, pass the barrier in a downstream direction, and a rat or other vermin trying to pass the barrier in an upstream direction will first face the second shutter.
  • the first shutter and the second shutter are arranged pivotably around each of their axes of rotation, e.g. at a first and a second hinge, respectively. They may be arranged so as to enable each of them to pivot independently from each other, although they may touch each other for certain combinations of angular values.
  • each shutter is, directly or indirectly, linked to the support structure, and each pivot around an axis of the hinge in, or on, the support structure.
  • the axis of rotation of the first shutter and/or the first locking mechanism may or may not be identical to an axis of rotation of the second shutter and/or the second locking mechanism.
  • first shutter and the second shutter are at different positions, and that these positions spaced apart along the first direction, such as along a direction parallel with the flow, the first shutter is placed at a first position with respect to the first direction, and the second shutter is placed at another position with respect to the first direction.
  • An advantage of having the shutters spaced apart may be, that a rat or vermin trying to open the second shutter (where the second shutter may be the shutter the rat or vermin is facing when trying to pass the barrier in an upstream direction) by rotating it from a first angular position towards another angular position, then the rat or other vermin may have difficulties in handling the partially opened second shutter when it furthermore has to open the first shutter which is placed further upstream.
  • the four angular positions defined above (v, w, x and z) is defined for the second shutter.
  • the first shutter and potentially other shutters within a barrier may also have different potential angular position, the angular positions for other shutters within the barrier may not necessarily be identical with the angular positions of the second shutter, but may potentially being relatively similar.
  • the second part of the locking mechanism forms a separate part from the the second shutter.
  • the first part of the locking mechanism being a blocking mechanism
  • the protrusion being the part of the blocking mechanism, which the corresponding protrusion of the second part of locking mechanism is arranged for engaging.
  • the second part of the locking mechanism being formed as a protrusion from the second shutter, said protrusion being an extension of the second shutter so that the second shutter and said protrusion is functioning as one mechanical coherent part, the protrusion preferable being a separate part composed with the second shutter, alternatively being a pre-manufactured part of the second shutter.
  • the parts of the locking mechanism are possible exchangeable so that the locking mechanism mounted in the barrier fit the exact dimension and slope of the sewage pipe system the barrier is installed in.
  • the second part of the locking mechanism forms an obstacle for the second shutter to rotate in a direction towards the upstream direction, as the said protrusion is engaging the support structure, the shape and size of the said protrusion thereby defining a first, closed position (v) when the barrier is undisturbed by vermin.
  • This embodiment of the invention is particularly, but not exclusively, advantageous in that the protrusion of the second shutter potentially can be formed in the exact dimension, so that the angle, defining the first closed (v), is the most optimal angle for stopping vermin opening the shutter and thereby preventing them from passing the barrier.
  • the second part of the locking mechanism comprises a form shaped as a hook.
  • a hook' may be understood that the protrusion is curved so as it forms a bend.
  • This embodiment of the invention is particularly, but not exclusively, advantageous in that a protrusion formed as a hook is very optimal for engagement with another component.
  • the said other component being the first part of the locking mechanism.
  • this embodiment of the invention is particularly, but not exclusively, advantageous in that a protrusion formed as a hook is very easily and relatively inexpensive to manufacture.
  • This embodiment of the invention is particularly, but not exclusively, advantageous in that by mounting the two shutters in a distance, so that it is certain, that the vermin cannot grab the first shutter from an upstream direction. Such distance thereby secure, that a vermin cannot unlock the locking mechanism by tipping the first shutter with its forelegs.
  • Many of the already existing vermin barriers on the market having two shutters inside the barrier have positioned the shutters in a distance so the vermin can unlock the locking system it selves, and thereby making the locking system more or less redundant.
  • the first shutter is arranged for acting as an opener of the second shutter, the first shutter rotating towards the downstream direction until engaging with the second shutter, thereby allowing the second shutter to rotate towards the downstream direction from a first, closed position (v) to a third, open position (w), so as to reduce damming of liquid in front of the barrier on the side facing the first shutter by allowing a flow of liquid passing in a downstream direction from the first shutter towards the second shutter.
  • This embodiment of the invention is particularly, but not exclusively, advantageous in that it enables a flow of liquid to open the barrier itself, so as dispensing with a need for actively opening the barrier for allowing a flow of liquid to pass the barrier.
  • the second part of the locking mechanism is capable of passing the first part of the locking mechanism so that the second shutter is rotatable to a first, closed position (v).
  • the barrier when a flow of liquid has opened the barrier in a downstream direction, the barrier can close it selves into a closed and locked position in a upstream direction, so that no vermin is allowed to pass the barrier.
  • the first shutter has a profile being smoother than a profile of the second shutter, preferably the second shutter has a profile being any one of: a toothed, a serrated, a notched or a pointy profile, and wherein the barrier is arranged to have reversible direction so that the definition of downstream and upstream direction can be reversed using the same barrier.
  • topographical features on the edge of the first shutter such as topographical features on the edge as observed from a direction away from the shutter where said direction is orthogonal to a plane of the shutter, may be larger and/or less smoothly than corresponding topographical features on the edge of the second shutter.
  • degree of smoothness it may be understood, to be smoothness on a length scale (such as 1 mm or 1 cm), which may be sensed by a rat or other rodent.
  • an edge may be less smooth by comprising pointy features, such as having any one of a saw-toothed profile, a toothed profile, a serrated profile and/or notched profile.
  • edges may differ in smoothness due to differences in quantitative measures, e.g., by differing in any one of amplitude (such as maximum height differences between maximum and minimum points of the profile), frequency and/or phase of teeth.
  • smoothness is to be understood to refer to a smoothness, which may be sensed by a rat or rodent upon touching said edge.
  • This embodiment of the invention is particularly, but not exclusively, advantageous in that the barrier can be used in any sewage pipe no matter how there downstream direction and upstream direction is defined, since the barrier is reversible.
  • this embodiment of the invention is particularly, but not exclusively, advantageous in that the second shutter is less likely to get dirty by contact with the solid matter.
  • this may be seen as an advantage when at least a part of an edge of the first shutter is smoother than a corresponding part of an edge of the second shutter, since the less smooth edge of the second shutter would then be relatively more likely to attract the solid matter, unless the - relatively smooth - first shutter is arranged for guiding the solid matter around the second shutter.
  • the invention also relates to a method for preventing vermin from passing through a pipe, such as a sewage pipe, preventing vermin from passing through a pipe in at least one direction in the pipe, at least in an upstream direction, said method comprising installing a barrier according to any of the preceding claims in the pipe.
  • FIG.1 shows a view of a barrier 100 suitable for installation at least partly in a sewage pipe and for allowing a sewage flow within the sewage pipe to pass the barrier in a first direction of the sewage pipe, the first direction being a downstream direction 106, and for preventing rats or other vermin (schematically shown above arrow 107) from passing the barrier in a second direction being opposite to the first direction upon installation of the barrier in the sewage pipe, the second direction being an upstream direction 107, said barrier comprising;
  • FIG. 1 furthermore shows that a profile, such as a second profile, of a part of an edge of the second shutter 103 is toothed, and that a profile, such as a first profile, of a part of an edge of the first shutter 102 is smooth.
  • support structure 101 is shown in FIG. 1 as the plate immediately above the shutters, but it may in general be understood to be at least a portion of the barrier 100, besides the respective shutters 102 and 103, on which the shutters are or may be mounted.
  • FIG. 2 shows an example of an inner portion 120 of a barrier 100 with a support element 101, a first hinge 108 and a second hinge 109, a first shutter 102 and a second shutter 103, and a locking mechanism with a first part 104 and a second part 105.
  • FIG. 2 furthermore shows an example of an inner portion 120 of a barrier 100, wherein the first hinge 108 is arranged with a larger vertical distance to the support structure 101 than the second hinge 109.

  • the second part of the locking mechanism 105 being a protrusion is in FIG. 2 shaped as a hook 105.
  • FIG. 4 shows a cross-section of an inner portion 120 of a barrier 100 in a configuration where a second shutter 103 is locked by a locking mechanism 104 and 105 being in a second closed position (x).
  • the position (x) defines the condition of the barrier 100 when it is disturbed by a vermin (not shown) tampering with the second shutter trying to pass the barrier.
  • FIG. 4 furthermore shows a an inner portion 120 of barrier 100, wherein a second part of the locking mechanism 105, is intended to engage with a first part of the locking mechanism 104, when the second shutter 103 is tampered to be opened by a vermin, when the engagement of the first 104 and second part 105 of the locking mechanism takes effect, the protrusion 105 of the second shutter 103 will encounter the blocking mechanism 102 on or near the first shutter 102 and thereby only make a limited rotation of the second shutter possible, the rotation being limited so that the second shutter 103 cannot be opened or passed by a vermin from the upstream direction 107, the locking mechanism thereby ensure the second shutter 103 being kept in a closed position, the position being a second, closed position (x).
