Description

The invention relates to a device for dispensing bait in a shaft structure, comprising a housing with a bait chamber and an opening through which a pest can enter the bait chamber. The invention further relates to an actuating tool for installing the device and to a system comprising the bait dispensing device and the actuating tool. To control pests, especially rodents like rats, in shafts, particularly sewage shafts, inspection shafts, or utility shafts, bait stations are used, which are positioned in the vertical shafts. Separate adapters, tension rings, or telescopic poles are typically used to position the bait stations. A disadvantage of the currently used systems is that the installation, inspection, and restocking of the bait stations generally require significant financial and operational effort. For example, when using adapters, shaft-specific adapters are necessary, such as those for different shaft diameters. Furthermore, installation and inspection usually require entering the shaft, which should be avoided for occupational safety reasons, particularly due to potential gas hazards or the risk of falling, or, if unavoidable, involves the use of complex safety equipment. Existing systems that are attached to climbing irons tend to be unstable or to detach during backflow events, especially surges of water. The object of the present invention was therefore to provide a device for dispensing bait that can be installed without entering the shaft and without additional attachments, while simultaneously ensuring high resistance to penetrating surge water. The problem is solved by a device for dispensing bait in a shaft structure, comprising a housing with a bait chamber and an opening through which a pest can enter the bait chamber, wherein a U-shaped recess for receiving a climbing iron is formed in the housing and the recess includes a support for the climbing iron, further comprising a fixing device adjustable by means of an adjusting device accessible from outside the housing, with which the climbing iron is pressed against the support in the mounted state. In the context of the present invention, a "shaft structure" is understood to be a shaft running at an angle of 60 to 90° to the horizontal, typically at an angle of 90°, particularly access shafts to supply or disposal channels, such as sewage pipes. These shaft structures generally contain rungs that serve as ladders for entering the respective channel. The design of the housing, with its U-shaped recess for receiving a rung, makes it possible to install the bait dispensing device within the shaft structure without additional components. Especially when installed in sewage channels, installation in an access shaft has the advantage that the bait chamber remains dry even with fluctuating water levels in the actual channel. The fixing device attaches the housing to the climbing iron, while the adjusting device serves to install the housing with an operating tool without the need to enter the shaft structure. The fixing device is designed so that the housing can be securely attached to the crampon and will not detach from the crampon even under external force, for example from splashing water. The fixing device can be any fixing device known to those skilled in the art that allows the housing to be fixed to the crampon by friction. Preferably, the fixing device comprises a plate that acts on the crampon from above, so that the crampon is clamped between the plate and the support on the housing when the device is mounted. In addition to friction-based fixing, positive-locking fixing is also possible. In this case, the plate and/or the support on the housing are shaped such that a recess in the shape of the crampon is formed, and the crampon is positively locked into the recess when the device is mounted. The fixing device preferably comprises a plate pivotable about an axis, the axis being mounted on the housing. When the device is mounted on the crampon, the pivotable plate is pressed down onto the crampon from above, so that the crampon is clamped between the support and the pivotable plate. It is further particularly advantageous if the pivotable plate is mounted such that an edge of the pivotable plate opposite the axis faces the opening of the recess for receiving the crampon. Such an alignment The swiveling plate has the advantage that when the swiveling plate is pressed against the climbing iron, not only is a first force component exerted in the direction of the support, but also a second force component acts perpendicular to it. This second force component pulls the housing towards the shaft wall, thus stabilizing the position of the device within the shaft structure. Particularly with climbing irons in the form of a U-shaped bar mounted in the shaft wall, it is further advantageous if the pivoting plate is mounted such that the edge of the pivoting axis opposite the main axis engages in the opening formed by the climbing iron and the sh
