    A one-way passage for animals and a game fence including the one-way passage Field of the invention The present invention relates to a one-way passage for animals comprising a first pole, asecond pole and a gate arranged between the first and second poles. The invention furtherrelates to a game fence including a first fence section, a second fence section, and a one-waypassage.
    Background of the invention lt is well known to user game fences to keep animals away from the traffic and trains. Thegame fences prevent wild animals from entering a road or railway, and avoid collisionsbetween the animals and cars driving on the road and trains on the railway. A problem is thatthere are always parts of the road which are not covered by the game fences, and then theanimals can sometimes enter the road despite the fences. The animals then gets upset andafraid and will run along the fence trying to find a passage to leave the road and enter the landon the other side ofthe fence. lfthe fences are provided with passages in the form ofopeningsin the fences, it is possible for the animals on the non-road side to enter the road through theopenings. There is a big safety problem today, both on roads and railways, namely that wildanimals end up on the wrong side of the fence installed to keep the animals away from thetraffic.
    Thus, the problem to be solved by the invention is how to let the animals on the wrong side(road side) of the fence through the fence and at the same time avoid that animals on theother side (land side) of the fence enter through the fence.
    Known solutions to this problem are openings in the fence, which are provided with hingedand spring biased gates on each side ofthe opening, which can only be rotated in one directionso that the animal can get out through the gate, but not back. This is a relatively sensitivesolution that requires some maintenance due to moving components, which are likely to jam.Since the elements of these gates are connected, there is no redundancy. lf the lower partsare restricted in their movement by snow or fouling, the gate will stop working.
    KR20110087370(A) discloses a one-way path structure provided to help wild animal to freelymove out of an entry prohibition region by opening a door in one direction. The one-way pathstructure comprises a fence, an induction pipe, and an opening and closing door. The fence iscomposed of a post and a net. The induction pipe is combined through the fence. Theinduction pipe is a tube type and has entrance and exit. The opening and closing door isinstalled inside the induction pipe and closes the path. The opening and closing door isinstalled to be opened toward in the exit direction.
    WO2004095915(A1) discloses a one-way gate for animals. The one-way gate comprises a firstgate element and a second gate element, which are moveable in one direction from a closed position to an open position. The one-way gate comprises locking means which are arrangedto prevent a movement of the first gate element from the closed position when the secondgate element is in the closed position. Thereby, it is nearly impossible for an animal to passthe one-way gate in the wrong direction.
    Another problem is that electrical lines for power transmission, such as power lines andoverhead contact lines, sometimes fall down on the game fence and by that power the gamefence.
    Obiect and summary of the invention lt is an object of the present invention to provide an improved one-way passage.
    This object is achieved by the one-way passage as defined in claim 1.
    The one-way passage comprises a first pole, a second pole and a gate arranged between thefirst and second poles. The gate comprises a plurality of elongated and flexible elementsarranged in parallel and extending from the first pole to the second pole. The flexibleelements are arranged successively along the length ofthe first pole. Each of the flexibleelements has a first end fixedly connected to the first pole, and a second end extending tothe second pole, and the second end of the flexible element bears against the second pole.The flexible elements are flexible in a direction orthogonal to longitudinal axes of the poles.The flexible elements are arranged individually flexible and by that individually movable inrelation to each other.
    The invention solves the problems of wild animals that are trapped between a road or railroadtracks, and a game fence. The invention makes it possible for the animals to pass through aself-closing gate. The one-way passage according to the invention is robust and durable, andthe need of maintenance is low compared to existing solutions. The one-way passageaccording to the invention has no movable mechanical parts, such as hinges. The one-waypassage according to the invention have few components (two poles and a number of flexibleelements) which are easy to replace if they are damaged. The one-way passage according tothe invention is cheap and easy to manufacture.
    The flexible elements are elongated and flexible. The flexible elements are, for example, barsor ribs. The flexible elements are made of a flexible material, such as wood, plastics, or fiberreinforced plastic. A suitable material is fiberglass reinforced plastic. The poles are suitablymade of wood. The flexible elements are arranged so they spring back when the animal haspassed through the passage.
    The flexible elements are flexible in a direction orthogonal to the poles so that an animalentering the gate is enabled to force the flexible elements to flex in a direction away from thesecond pole and by that allows the animal to pass through the gate, and the flexible elementsswings back when the animal has passed through the gate. The flexible elements are prevented from flexing in the opposite direction by the second pole and by that preventanimals from the outside ofthe passageway from passing through the gate.
    The flexible elements are individually flexible, which means that the each of the elements canbe bent independent of the other elements. Thus, the animals only need to bend a number ofelements corresponding to the height of the animal. A small animal then needs to bend fewerof the elements compared to a larger animal to be able to enter the gate. Accordingly, asmaller animal needs to apply less force than a larger animal. Thus, the gate is suitable forsmall as well as large animals.
    When the passage is used, the poles are arranged vertically, and the flexible elements arearranged horizontally. The flexible elements can only flex in one horizontal direction(outwards). The flexible elements are prevented from flexing in the opposite horizontaldirection by the second pole.
    Preferably, the number of flexible elements is at least 5, more preferably at least 10, and mostpreferably at least 15. The number of flexible elements and the distance between themdepends on the type and size of the animals. The distance between the flexible elementsshould be selected so that the animal will realize that it is possible to force the gate. Thedistance between the flexible elements may vary. For example, the distance between thelower elements can be shorter than the distance between the upper elements to avoid thatsmall animals can penetrate between the flexible elements and by that enter the road side ofthe gate.
    According to an embodiment ofthe invention, the flexible elements are made ofan electricallyinsulating material, such as plastics, to electrically insulate the game fence. Thus, powering ofgame fences due to fallen down power lines is avoided.
    According to an embodiment of the invention, the flexible elements are also flexible in adirection in parallel with longitudinal axes of the poles. Thus, the flexible elements can alsoflex downwards (in a vertical direction) due to the weight of the animal and by that the animalis prevented from getting stuck in the gate.
    According to an embodiment of the invention, the flexible elements and the second pole areprovided with means to form a back stop to prevent the flexible element to be moved in adirection towards and beyond the second pole. For example, the second end of the flexibleelements are provided with a hook that can hook into corresponding devices on the secondpole to form a backstop to prevent the flexible elements to be pressed backward over thesecond pole.
    According to an embodiment ofthe invention, the flexible elements are arranged so that theyhave a decreasing spring constant towards the second end. This embodiment enables theadjustment ofthe opening force while maintaining the strength of the flexible elements.
    According to an embodiment of the invention, the flexible elements are flexible ribs.
    According to an embodiment of the invention, the second pole is equipped with a silencingdevice which prevents that unpleasant noise occurs when the gate is shut after a passage ofan animal, or if the animal is investigating the flexible elements.
    According to an embodiment of the invention, the first pole is designed so that it can beadjusted in a vertical direction and rotated so that flexible elements abuts the second poleand to achieve a suitably force against the second pole.
    Another object ofthe present invention is to provide an improved game fence including a one-way gate. This object is achieved by a game fence as defined in claim 7.
    The game fence comprises a first fence section, a second fence section, and a one-waypassage according to the present invention arranged between the first and second fencesections.
    According to an embodiment of the invention, the first fence section is connected to the firstpole and a second fence section is connected to the second pole, and the first and secondfence sections are arranged at a distance from each and facing each other so that they form acorridor for guiding the animals towards the gate.
    According to an embodiment of the invention, the gate is skewed at an angle less than 90degrees in relation to the first and second fence section so that an output end of thepassageway is wedge-sha pe.
    The game fence has a first fence section including the first pole and a second fence sectionincluding the second pole, and an one-way passage formed between the first and secondfence sections, wherein the first and second fence sections are arranged at a distance fromeach other and opposite each other so that they partly overlap each other by that forming apassageway for guiding the animals towards the passage. The one-way passage comprises agate arranged between the first and second poles and having one side facing the passagewayand the other side facing away from the passageway.
    Brief description of the drawings The invention will now be explained more closely by the description of different embodimentsofthe invention and with reference to the appended figures.

    Fig. 2 shows an example of one-way passage for animals according to the invention.Fig. 3 shows part of the one-way passage in more details.
    Fig. 4 shows an example of a flexible element.
    Fig. 5 shows the flexible element when it is bent downwards.
    Fig. 6 shows a game fence according to a second embodiment ofthe invention.
    Detailed description of preferred embodiments of the invention Figure 1 shows a game fence comprising a first fence section 12, a second fence section 14,and a one-way passage for animals arranged between the first and second fence sections. Theone-way passage comprises a first pole 2, a second pole 3 and a gate 10 arranged betweenthe first and second poles.
    Figure 2 shows an example of one-way passage for animals according to the invention. Thegate 10 comprises a plurality of elongated and flexible elements 1 arranged in parallel andextending from the first pole 2 to the second pole 3. The flexible elements are arranged at adistance from each other along the length of the first pole 2. Each of the flexible elements 1has a first end 1a attached to the first pole 2, and a second end 1b bearing against the secondpole 3. The flexible element bear on the second pole at 5, as shown in figure 2. The flexibleelements can, for example, be directly attached to the first pole by means of screws, nails,rivets or bolts, or attached to a rail fixedly attached to the first pole. A lower part 6 of the firstand second poles is fasten in the ground.
    The second end 1b is not attached to the second pole 4, and can be moved away from thesecond pole when an animal pushes the element 1. The flexible elements are flexible in adirection orthogonal to the poles so that they can be bent away from the second pole. Theflexible elements are arranged individually flexible and by that they can be individually bent,as shown in figure 1. The flexible elements 1 are bent away from the second pole to an openpositon when they are pushed by an animal, to form an opening for the animal to passthrough. Only the pushed elements 1 are bent and moved to the open position, the otherflexible elements 1 remain in a closed position. Thus, the size of the opening is adapted to thesize ofthe animal.
    For example, the flexible elements 1 are flexible and spring back ribs. Suitably, the flexibleelements 1 are identical. The gate 10 comprises several identical flexible and spring backelements 1, fastened in the first pole 2. The flexible elements extend horizontally to thesecond pole 3, where they touch the side of the pole 3 facing away from the roadway orrailway tracks. Each flexible element 1 is individually secured to the first pole 2 and thereforeindividually openable. This means that smaller animals do not need to push all the flexibleelements to get through the gate. The individually openable elements also achieve that thefunction of the gate is unaffected by e.g. snow or vegetation which may prevent the lowerflexible elements from moving. The lowest flexible element can be mounted on a height thatenables and facilitates the removal of grass and brush adjacent to the gate without damagingthe gate. Since the opening of the gate depends on the inherent resiliency properties of theflexible elements 1 no moving parts are needed, and the lock is inherently self-closing. Theflexible elements abut a reverse side ofthe second pole 3, and thus cannot be opened towardsthe roadway or railway tracks.
    The gate is a robust and movements ofthe ground due to e.g. frost does not affect the functionof the gate. By manufacturing the flexible elements of an electrically insulating material, thegate will function as an insulator of the game fence at places where the risk of falling powerlines exists, especially at railway catenary and also where high-voltage lines cross the road or run in parallel to the road. The gate can thus be used for sectioning of game fencing thatcurrently takes place in another way.
    The invention is a self-closing one-way passage that can be fitted into an existing game fenceto allow wild animals, which happen to be on the wrong side of the fence, to cross the fenceand come back to their habitat. The device comprises of a number of similar flexible, spring-back elements, such as ribs, which are attached to a first pole and horizontally extending to asecond pole, which the flexible elements bear on, so that the elements can only be bent inone direction, and let the animal pass. To further ensure that the flexible elements are notbent past the second pole, hooks are mounted on the second pole and ribs. The invention isrobust and without any moving parts and with a redundancy in the function, the flexibleelements are individually secured to the first pole and not connected to each other. Becausethe flexible elements are made of an electrically insulating material, the gate will also functionas an insulating section of the fence.
    The distance between the flexible elements may vary. For example, the distance between theflexible elements may vary between 0.08 and 0.35 m, and preferably between 0.1 m and 0.3m. For example, the distance between the lower elements can be shorter than the distancebetween the upper elements to avoid that small animals penetrate between the flexibleelements and by that enter the road side of the gate. For example, the distance between thelower flexible elements is between 0.08 m and 0.15 m and the distance between the upperflexible elements is between 0.25 m and 0.35 m.
    Figure 3 shows part ofthe one-way passage according to one embodiment ofthe invention inmore details. ln this embodiment, the flexible elements 1 and the second pole 3 are providedwith means to form a backstop to prevent the flexible element to be moved in a wrongdirection, i.e. in a direction towards and beyond the second pole, as shown in figure 3. Thesecond end of the flexible elements are provided with a hook 7 that can hook into acorresponding device 8 on the second pole 3 to form a backstop to prevent the flexibleelements to be pressed backward over the second pole. The second pole 3 can be equippedwith a silencing device 9, which prevents that unpleasant noise occurs when the gate is shutafter a passage of an animal, or ifthe animal is investigating the flexible elements.
    The length of the flexible elements is suitable between 2 - 3 m. The width of the flexibleelements may, for example, vary between 40 mm and 80 mm. The width of the flexibleelements may vary so that the width is decreasing towards the second end of the element toachieve a decreasing spring constant towards the second end. The thickness of the flexibleelements may, for example, vary between 5 mm and 15 mm. The thickness of the flexibleelements may vary so that the thickness is decreasing towards the second end of the elementto achieve a decreasing spring constant towards the second end.
    Figure 4 shows another example of a flexible element designed so that it has a decreasingspring constant towards the second end. ln this embodiment, the flexible element is tapering towards the second end. This embodiment enables the adjustment ofthe opening force whilemaintaining the strength ofthe flexible elements.
    Preferably, the flexible elements 1 are also flexible in a direction in parallel with longitudinalaxes of the poles. Thus, the flexible elements can also flex downwards (in a vertical direction)due to the weight ofthe animal and by that the animal is prevented from getting stuck in thegate, as shown in figure 5.
    Figure 6 shows a perspective view of a game fence according to a second embodiment of theinvention. A passageway is formed between two fence sections 20, 22. There is an openingbetween the two fence sections in one end ofthe passageway allowing an animal to enter thepassageway and a gate located in the other end of the passageway. The gate is made by aplurality of flexible elements arranged between two poles.
    The game fence includes a first fence section 20 attached to a first pole 2 and a second fencesection 22 attached to a second pole 3, and gate 10 formed between the first and secondfence sections, wherein the first and second fence sections are arranged at a distance fromeach other and opposite each other so that they face each other and partly overlap each otherby that forming a passageway for guiding the animals towards the passage. The one-waypassage comprises a gate arranged between the first and second poles and having one sidefacing the passageway and the other side facing away from the passageway. The gate 10 isskewed at an angle less than 90 degrees ln relation to the longitudinal axis of the first andsecond fence section so that an output end of the passageway is wedge-shaped. The gatecomprises a plurality of elongated and flexible elements arranged in parallel and extendingfrom the first pole to the second pole. Each of the flexible elements has a first end directlyfixedly attached to the first pole, or attached to a rail fixedly attached to the first pole, and asecond end extending beyond the second pole, so that the flexible element rests on thesecond pole on the outside of the passageway. The flexible elements are made flexible andresilient in a direction orthogonal to the poles (a horizontal direction) so that an animalentering the gate is enabled to force the flexible elements to bend in a direction away fromthe passageway and allows the animal to pass through the gate. When the animal has passedthrough the gate, the bent flexible elements swings back and by that prevent animals fromthe outside ofthe passageway from passing through the gate.
    The present invention is not limited to the embodiments disclosed but may be varied andmodified within the scope of the following claims. For example, the number of flexibleelements can vary, and the distance between the flexible elements can vary.
