Abstract: A trap for exterminating pests, preferably rats in sewers, said trap comprising: a trap housing and a bait mechanism. The trap also has a trigger mechanism capable of detecting the presence of a rat and releasing a killer mechanism when the rat is within the total range of the killer mechanism; and a trapper mechanism capable of detaining an animal. The trap may also convey a killed animal from a first position, in which discharge of the killed animal will not entail that it is conveyed away by water running through the sewer, to a second position, in which discharge of the killed rat will entail that it is conveyed away by water running through the sewer.

Abstract: 1. A trap for rodents, including in particular rats, said trap comprising: a housing; and a trapping chamber in which a passage extends from the side(s) of the housing. The trap further comprises two electric poles, of which the one electric pole is disposed outside the trapping chamber and a reservoir. The trap is moreover configured with a transport mechanism for the transport of the trapping chamber with rodent between a lower position in which the rodent is able to run into the trapping chamber and an upper position in which the trapping chamber is able to discharge a destroyed rodent into the reservoir. The trapping chamber and the electric poles comprise means to the effect that the electric poles can be caused to be situated close to each other within the trapping chamber.

Abstract: The invention relates to a trap for animals, in particular rats or mice, and for being arranged on a substantially horizontal face, where this meets a substantially vertical face. The trap comprises: a trap housing and a first flange and a second flange that are connected substantially at right angles to the effect that the trap can be arranged in two positions, where the substantially horizontal face meets the substantially vertical face. The flanges and the faces of the trap span, in both positions, a volume which is delimited such as to define a passage in which a rat or a mouse may move. The trap housing further comprises an inner passageway that a rat or a mouse may run into, said passageway extending from the one flange and into the trap housing. Inside the passageway there is a trigger mechanism and a killer mechanism.

Abstract: A rat trap (1) comprising a power supply (80) and means (3) for killing a rat and a first sensor adapted to detect the presence of a rat in the space within the reach of the killing means and where control means are arranged capable of receiving a signal from the first sensor, and being adapted for activating the killing means (3) to kill the rat when the presence of the rat is detected by the sensor according to the invention the trap further comprise a second sensor (85) for detecting light, and the control means is capable of receiving a signal from the second sensor (85) and being adapted for deactivating the killing means (3) or the first sensor for a period of time after the detection of light by the second sensor. Hereby it is possible to prevent accidents due to e.g. erroneous activation of the trap in case of ordinary localized work illumination, including e.g. also in daylight at ground level or in artificial work illumination at the bottom of a shaft.

Abstract: The invention relates to a fastener mechanism, optionally comprising a shield. The fastener mechanism is intended for use in preferably cylindrical cavities, such as sewers. It comprises adjustable engagement means for engagement with the inner sides of the cavity; and an activation unit for adjusting the engagement means to the effect that they can be adjusted between a first position in which they are in engagement with the inner sides of the cavity, and a second position in which the engagement means allow introduction of the fastener mechanism into the cavity.
