Rodent Entry Prevention Device

Abstract

The present invention relates to a device (1) for preventing entry of a rodent through a pipe comprising a jacket (2), a first gate plate (3) and a locking device (4), where the jacket (2) is adapted for mounting in the discharge pipe, where the first gate plate (3) is pivotally arranged inside the jacket (2), and where the locking device (4) is arranged in connection to the first gate plate (3), wherein a second gate plate (6) is pivotally arranged at a distance (X) from the first gate plate (3) inside the jacket (2) and connected to the first gate plate (3) by means of a connection assembly (8).

Description

FIELD OF THE INVENTION[0001]The present invention relates to a device for preventing entry of a rodent through a pipe comprising a jacket, a first gate plate and a locking device, where the jacket is adapted for mounting in the discharge pipe, where the first gate plate is pivotally arranged inside the jacket, and where the locking device is arranged in connection to the first gate plate.BACKGROUND OF THE INVENTION[0002]Through time rodents have tried and succeeded in invading the human habitation, as the survival instinct of the rodents makes them e.g. seek for food or better living conditions during cold seasons or famines.[0003]In developed areas e.g. cities with sewage systems, rodents and especially rats are a major problem, because they breed fast, spread hazardous human diseases, and destroy building constructions as they nest or invade a building.[0004]It is a fact that every major city has a growing population of rats, which typically live and breed in the cities sewage sys...

AI Technical Summary

Benefits of technology

[0010]Thus an object of the present invention is to provide a rodent entry prevention device, which significantly reduces the risk of rodents, especially rats, invading a building through any pipe installation and which at the same time allows unimpeded flow of water through the pipe installation.

Problems solved by technology

In developed areas e.g. cities with sewage systems, rodents and especially rats are a major problem, because they breed fast, spread hazardous human diseases, and destroy building constructions as they nest or invade a building.

The disadvantages of the aforementioned means are that when using e.g. poisons the rats sometimes die in unknown places of a building causing severe odour nuisances.

Furthermore, rats killed by poison can represent a health risk for a carnivore eating the rats, meaning that pet animals, like dogs and cats, are exposed, thus trapped or killed rats have to be disposed of.

Everyone of these rodent entry prevention devices prevent a number of rodents from invading a building, however studies of rats have shown that the animals are very persistent and inventive and try to circumvent the device.

As the rats are quick learners, they often succeed in doing so hence the usefulness of the device is significantly reduced.

Furthermore, another disadvantage of such devices is that they do not allow unimpeded flow through the pipe installation.

Thus the risk of clogging the pipe installation increases, and since the rats can swim, a water trap does not provide an efficient barrier to rats.
