DETAILED DESCRIPTION OF THE INVENTION

[0063] The trap and/or monitoring box 100 according to the invention has a large inner compartment or cavity 105 compared to known trapping or monitoring constructions.

[0064] The large inner cavity appeals to rodents for hiding and nesting and incite rodents to explore the compartment. In general, a rodent trap and/or monitoring box 100 according to the invention is resting on a ground level surface, which ground level surface may be constituted of a material such as concrete, asphalt, pavement, soil, sand, gras or similar. Normally, a rodent trap and/or monitoring box 100 according to the invention is not constituted with a bottom at ground level, therefore a rodent may pass under or into the housing of the rodent trap and/or monitoring box 100 without experiencing a change in ground level surface, at least if the rodent travel at a certain path.

[0065] Normally, the rodent trap and/or monitoring box 100 comprises a housing constituted of one or more walls which are extending upward, and which may be extending substantially vertically to form a cavity 105. The cavity 105 may have an upward opening or top opening which opening is provided with a lid or cover 118, e.g. the cover may be part of a plant box or a garbage bin or ash tray or a storage room positioned above or on top of the cavity 105.

[0066] That the walls are “substantially” vertical means that wall(s) may be straight or curved or inclined but to some extend the walls extend in a vertical direction and form the inner cavity 105. Shape or inclination of the walls is not significant for the invention. The walls, and therefore the cavity 105, may have any cross-sectional form, e.g. circular or oval or polygonal such as rectangular or square.

[0067] In general, the walls of the housing may be constituted of any material e.g. a polymer such as PE e.g. HDPE, PVC, PP, PC, ABS or PLA, or wood e.g. hardwood such as oak, maple, or walnut, or softwood such as pine, spruce, beech or the like, or metal e.g. steel, iron, zinc, aluminum or the like. The housing may also have a decorative purpose in public space where e.g. the top or cover may comprise or be constituted of a plant box and/or the side walls may be covered with advertisements or messages.

[0068] A rodent trap and/or monitoring box 100 according to the invention may comprise a platform 112 inside the cavity 105 or forming the bottom of the cavity 105. The platform 112 is raised so much from the ground that a rodent such as a rat or a mouse, will have to choose whether to jump onto the platform or to pass below the platform. The platform 112 may be raised at least 2 cm above ground level, e.g. at least 3 or at least 4 or at least 5 cm or at least 7 cm or at least 10 cm above ground level. The position above ground level of the platform 112 may depend on which rodent in particular the box 100 is desired to target. The platform 112 may comprise an access opening 103 or at least an access edge or open side 103a facing an opening to ground level which access opening 103 or edge 103a gives a rodent access to the platform 112 from ground level. In general, the distance from the edge of the access opening 103 or the access edge 103a, to a wall of the housing, or to a trap positioned on the platform, at least at one position or along one edge, should be at least a body length of the type of rodent which the box 100 is determined to target. This distance d will allow the rodent to enter onto the platform 112 without meeting any obstacles and even the most cautious and timid rodents will dare to explore a horizontally open space.

[0069] A box 100 according to the invention is relatively large compared to ordinary rodent traps seen in the public area. A box 100 according to the invention will normally be large enough to have a function in the public room e.g. the box 100 may support one or more detachable plant boxes or containers, or the box 100 may comprise an upper compartment i.e. a compartment above the platform 112 which may be used to store e.g. tools for maintaining parks or roads, alternatively the rodent trap box 100 may support a bench surface or a sculpture or another feature having a functional purpose—practical or ornamental—in the public environment. The box 100 may comprise a top part having a functionality not related to trapping or housing rodents, or alternatively, the box 100 may comprise a top part providing the impression that it has another functionality and it may therefore not be perceived as a rodent trap or a rodent monitoring device.

[0070] In general, in respect of size, the inner cavity 105 of the box 100 may be at least 20 cm high, i.e. the inner cavity 105 extends 20 cm from ground level to a top surface of the inner cavity 105, or the inner cavity 105 is at least 30 cm high, or at least 40 cm high.

[0071] In general, a platform 112 may be placed inside the inner cavity 105 or constitute the bottom of the inner cavity 105 at a level above ground level and at a level below the top surface of the inner cavity 105, preferably the platform 112 is positioned at a raised level.

[0072] In general, the housing of the rodent trap and/or monitoring box 100 may comprise legs or wheels extending below the inner cavity 105 or below a platform 112, which legs or wheels or similar may support the walls of the housing at ground level. Alternatively, the walls of the housing may rest directly on the ground level.

[0073] A platform 112 may be fixed to the walls of the housing and carried by the housing, or the platform 112 may be movably mounted relative to the housing e.g. on elongated posts or walls or wheels allowing the platform 112 to be moved relative to the housing or stationary walls of the box 100 e.g. sideward by sliding or wheeling the platform 112 out of the housing or upward by lifting the platform 112 up.

[0074] The platform 112, i.e. the upper surface of the platform 112, should be large enough to allow a rodent to reside or stay on the platform 112, i.e. between the edge of the platform 112 constituting an entrance opening 103, 103a and either a wall e.g. forming part of the cavity 105 or a trap mechanism 114, the distance d should be at least the body length of the rodent, preferably longer. Such a minimum distance drain allows the rodent to enter upon the platform 112 and examine the space.

[0075] FIG. 1 discloses a first embodiment of a rodent trap and monitoring box 100 according to the invention, FIG. 1 shows a view where the top cover of the box is removed, and the viewer looks down into the cavity of the box or housing. This embodiment of the box 100 is configured to support one or more detachable plant boxes/containers which constitutes a top cover for the inner cavity 105 during operation. The box 100 comprises a plurality of connected platforms 112 positioned at a raised level and access openings 103 allowing rodents to enter up onto the platform 112 during operation. The first embodiment of the box 100 shown in FIG. 1 is rectangular comprising a front wall 108, a rear wall 110 and two side walls 104, 106. The front wall 108, the rear wall 110, and the sidewalls 104, 106 are securely connected together using one or more supports 124 and fasteners.

[0076] The platforms 112 are securely affixed to or positioned or formed at the raised level within the box 100 at the bottom or lower end of the cavity 105. The platforms 112 are configured to allow a user to deposit food as a means of attracting and capturing rodents, such as rats or mice. The relatively large platforms 112 are also configured to allow the user to deposit nesting material to attract rodents seeking a place to have their young. The platforms 112 may be made of a natural material such as wood or a wood product such as plywood. Rodents especially rats finds natural materials appealing and are more likely to enter a surface made of a natural material, however, the material should also have a relatively smooth surface as it might be necessary to clean the surface to remove food remains and/or dead rodents.

[0077] In general, a rodent trap box 100 may comprise a user access opening 115 allowing a user to access the cavity 105 or a platform 112 of the box 100. The user access opening 115 may extend over the complete top as shown in the first embodiment, or the user access opening 115 may be a partial opening in a side wall of the housing or extend over a complete side wall of the housing. Alternatively, the housing being constituted of walls and a top cover may stand directly on the ground (i.e. the housing has no bottom or only a partial bottom) and the housing may then be lifted or pivoted around a lower side of a wall to provide an access opening 115 to the inner cavity.

[0078] In general, the user access opening 115 may be closed by a cover during operation which cover can prevent unauthorized access to the inner cavity of the housing or box. The cover may be provided with a locking mechanism e.g. a locking mechanism which is to be opened by a key or a code which is only available to authorized personnel.

[0079] A user access opening 115 may comprise a side opening, which side access opening 115 may be closed by a cover or a door attached to a wall of the housing of the box 100 by a hinge, or the side access opening 115 may be closed by a cover being opened and closed by sliding a part, e.g. a platform, horizontally along guiding rails mounted inside the cavity 105 like a drawer. Also, the user access opening 115 may be a top opening which opening may be protected or closed by a top cover 118. A top cover 118 may be connected to a side wall of the housing of the box 100 by a hinge, consequently the top cover may be opened providing access to the cavity 105 by pivoting the top cover relative to the side wall where the hinge is attached, alternatively, a top cover may be constituted of a plate or a lid which may be lifted off when the user wants access to the inner cavity.

[0080] An automatic trapping device 114 may be securely affixed to a wall or to the platform 112 within the cavity 105 of the box 100 using one or more fasteners such as screws, nuts, or bolts. The automatic trapping device 114 may be configured to effectively trap or kill rodents including rats and mice. The presence of a trap is optional, but many users prefer to have rodents killed instead of solely having the rodent population monitored. However, the number of killed rodents adds information to the monitoring of the population, and the addition of a trapping device may therefore give a more complete picture of the rodent population.

[0081] The box 100 may comprise a camera 122. The camera 122 is positioned in such a way that it may monitor rodent activity e.g. below the platform 112 or e.g. to and/or from the platform 112 or e.g. on a platform 112. The presence of a camera is optional, the box or the platform may instead comprise sensors such as weight sensors which indicate when a rodent enters into the cavity or up onto a platform. However, a camera is a preferred indicator for rodent presence in the box as the camera will allow the user to see how the rodent behaves inside the box. A camera alone, or a camera in combination with a sensor such as a weight sensor, may be used for identification of rodents entering into the box.

[0082] In general, one or more detachable plant boxes/containers may be securely positioned on a top portion of the box 100, e.g. plant boxes/containers may be positioned partly lowered into an upward opening of the cavity 105 of the box 100.

[0083] FIG. 2 discloses the inside of the first embodiment of the box 100 from a different angle than FIG. 1 as FIG. 2 discloses the platform 112 inside the cavity 105 of the box 100 and a rail 117 supporting the housing of the box 100 at ground level. In an exemplary embodiment, the platform 112 is securely positioned to a wall at a raised level within the cavity 105 of the box 100. The platform 112 may be designed as feeding platform or it may be designed as appealing to a rodent for nest-building and hiding. A purpose directed design is obtained by choosing materials and shapes e.g. hides or openings which appeal to e.g. a particular rodent for a particular purpose.

[0084] FIG. 3 discloses a side view of the first embodiment of the box 100, and this view illustrates the position of an entrance opening or a hole 116 in a wall of the box 100. The entrance opening or hole 116 is positioned at ground level below the platform 112 at the front wall 108 and at the rear wall 110, normally an entrance opening 116 is open downwards and a rodent may enter into the box 100 while walking directly on the ground surface, i.e. the rodent will not experience a change in the surface when entering into the box 100, the rodent will instead experience an opportunity to hide as it enters below the platform 112.

[0085] The box 100 may comprise one or more entrances 116 at any one side or at all sides of the box 100. The entrance opening or hole 116 may be disposed along at least any one side or other sides of the box 100 for the rodents to enter at ground level. When a rodent has entered the box 100 and is hiding under the platform 112, the rodent will experience an opportunity to enter the platform 112 where the rodent may get into contact with the automatic trapping device 114 (shown in FIG. 1) or may be registered by a camera 122 or a different counting or registration mechanism.

[0086] The opportunity to enter a platform 112 may comprise a downward access opening 103 in the platform 112, and such an access opening 103 may have any shape or edge. E.g. the platform 112 is constituted of a frame work with many access openings 103, or the platform 112 is e.g. constituted of planks or boards positioned with a distance between them which distance forms an access opening 103, or the platform 112 may be constituted of a board provided with cut openings or the like. In the first embodiment of FIG. 1, the platform 112 is constituted of 3 boards placed with distance between neighboring boards together with plate mounted at one end of the box 100, the distance between two boards constitute a downward access opening 103 according to this embodiment.

[0087] According to one embodiment, a camera 122 may be securely affixed inside the cavity 105 of the box 100. The camera 122 may be affixed to the inner surface of a wall of the box 100, e.g. at such a level that it is possible for the camera 122 to monitor rodents accessing the platform 112, or alternatively at such a level that it is possible for the camera to monitor rodents entering into the box 100 at ground level beyond the platform 112. Alternatively, other means for registration of rodent activity may be mounted inside the cavity 105, either together with a camera or without a camera.

[0088] If the box 100 is provided with a camera, the box 100 may be used to monitor rodent activity in an area, and if the box 100 is provided with a trap such as an automatic or electric trap or a mechanical trap, it may be used to trap and/or kill rodents in an area monitored by the box, the box 100 may comprise both a camera 122 for monitoring activity and a trap for killing or capturing rodents.

[0089] FIG. 4A-4C shows three different views of a second embodiment of a box according to the invention. The second embodiment comprises a closed box 100 having vertical walls. The four side walls 104, 106, 108, 110 and the top cover 118 are prepared from molded polymer. Entrance openings 116 extending in approximately half the length of opposed walls 108, 110 are positioned at ground level. The not shown inner cavity 105 is closed by a hinged top cover 118 which top cover 118 has an open position allowing access to the inner cavity by a user and a closed position preventing access to the inner cavity 105 by users and by-passers. The box 100 also comprises a locking mechanism 119 which prevents pivoting the top cover 118 away from the closed position and into an open position, the shown locking mechanism 119 may be secured by a padlock.

[0090] FIG. 4D shows a platform 112 which may be placed at a raised level inside the inner cavity 105 of the box 100 of the second embodiment. The outer perimeter of the platform 112 is fitted to the inner surfaces of the walls of the box 100. Further, the platform 112 comprises an access opening 103 allowing rodents to enter upon the platform 112 from ground level, the access opening 103 is cut out of the plate constituting the platform 112.

[0091] FIG. 5 shows a third embodiment of a box 100 according to the invention. The housing of the box 100 according to the third embodiment is rectangular comprising four upright or vertical walls and is provided with a plant box on top. Like the first embodiment, the third embodiment comprises a front wall 108, a rear wall 110 and two side walls 104, 106. The front wall 108, the rear wall 110, and the sidewalls 104, 106 are securely connected together forming a housing. A user access opening 115 is positioned at one end of the housing and appears when the side wall 106 of the housing is pulled away from the stationary walls 108, 104, 110 of the housing.

[0092] The third embodiment of the box 100 according to the invention is constructed to be positioned in the public domain and comprises a flower or plant box at an upper level, i.e. above the not disclosed inner cavity. The upper level is open to the public and people passing by may both see and touch what is the placed at this level. Beyond this upper level is a closed inner cavity 105 which in a horizontal plane is limited or defined by the inner surfaces of the four walls of the housing and which upward is limited by top cover which may be constituted by the bottom of the plant box and down ward is limited by the ground level surface. The lower end of the walls of the housing may be positioned directly on the ground level or may be raised up above ground level by legs extending from the lower end of the walls or by wheels position below the walls. At least the lower ends of the two walls 104 and 106 are provided entrance openings 116 at ground level allowing rodents to enter into the housing. A platform 112 is placed inside the inner cavity 105 at a level above ground level and the platform 112 is fixed to the side wall 106. When the side wall 106 is pulled away from the stationary walls 108, 104, 110 of the housing, the platform 112 is also pulled out in the open through the user access opening 115. At this open state, a user may clean a trap positioned on the platform 112 or place food or maintain a camera, etc.

[0093] The third embodiment of the box 100 is relatively large, the length of the housing may be around 1.2 m creating an inner cavity 105 of approximately the same length. The total height of the walls of the housing is around 60 cm, and the platform 112 is positioned around 10 cm above ground level, while the complete height of the inner cavity 105 is around 40 cm. An inner cavity of this size will primarily appeal to rats having a head and body length ranging from 15 to 28 cm.

[0094] FIG. 6 shows a fourth embodiment of a box 100 according to the invention. The fourth embodiment comprises the same elements as the third embodiment. However, the platform 112 is supported by wheels 120 which makes it easier and smoother to pull the side wall 106 away from the stationary walls 108, 104, 110 of the housing. The platform 112 comprises a rodent access opening 103 positioned near one end of the platform 112 this position of the rodent access opening 103 provides ample space for a rodent to jump onto the platform 112 and explore the room. The platform 112 may be adapted to fit into the inner cavity 105 provided by the inner surfaces of the walls of the housing, however, the platform 112 may also be smaller allowing a rodent to enter the platform 112 not only by the rodent access opening 103 but also by one or more rodent access edges 103a.

[0095] FIG. 7 shows a fifth embodiment of a box 100 according to the invention. The housing of the box 100 according to the fifth embodiment is rectangular comprising four upright or vertical walls and is provided with a plant box comprising a trellis 121 extending upward above the housing. Beside the trellis, the fifth embodiment comprises the same elements as the third embodiment of FIG. 5. However, the housing is smaller, approximately half the length of third embodiment, i.e. the inner cavity is around 60-70 cm in length.

[0096] FIG. 8 shows a see-through view of the fifth embodiment which illustrates how the upward cover 118 of the inner cavity is constituting a closed bottom of the upward open plant box.

[0097] FIG. 9A-9D shows a sixth embodiment of a rodent trap and/or monitoring box 100 according to the invention.

[0098] FIG. 9A shows the sixth embodiment in a closed state i.e. a state where the inner cavity 105 is closed as the user access opening 115 is covered by a side wall 106. The side wall 106 comprises an entrance opening 116 which in the closed state is positioned at ground level. The opposite wall 104 may also comprise such an entrance opening 116.

[0099] FIG. 9B shows the sixth embodiment in a semi-open state. The side wall 106 constitute a cover for the user access opening 115 which user access opening 115 has been partly revealed in FIG. 9B. The two corner supports 124 to which the side walls 104 and 110 are fixed, comprises guiding rails in which the side wall 106 can slide up and down between a closed and an open position. When the cover constituted by the side wall 106 is positioned in the semi-open state, it is possible to see a stationary platform 112 being mounted on supports fixed to 2-3 walls of the housing.

[0100] A top cover 118 defining the upper limit of the inner cavity 105 can be seen just below the partly lifted cover/side wall 106.

[0101] FIG. 9C shows the sixth embodiment in a state where the cover/side wall 106 has been completely removed. This view further makes it possible to an end wall 123 of the plant box.

[0102] FIG. 9D shows a downward view at the support 124 between the stationary wall 108 and the movable cover/side wall 106. Close to this corner is a locking mechanism 119 positioned. One part of the locking mechanism 119 is fixed to a stationary part e.g. the wall 123 of the plant box while a second part of the locking mechanism is fixed to the movable part i.e. the cover/side wall 106. The locking mechanism 119 may lock the position of the cover/side wall 106 in at least two positions relative to the stationary parts of the box 100. Preferably, the locking mechanism 119 may also lock the cover/side wall 106 in a third position, e.g. the position shown in FIG. 9C, at which position the user access opening 115 allows for a user to clean or maintain traps or cameras positioned on the platform 112 or attached to the walls inside the inner cavity 105.

[0103] The box 100 is simple in structure, convenient to install/mount and use, high in sensitivity, environmentally friendly, and provides a high degree of safety, it is e.g. possible to prevent user access to the inner cavity of the box 100 by a padlock or other locking mechanism, a nice appearance, effective for trapping rodents, and has a high market prospect. The box 100 may be inexpensive or luxurious depending on the material chosen for construction, it is simple in design, reliable, and may be able to withstand harsh environments.
