DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

(15) Referring now to the accompanying drawings, we will describe indicative applications of the trap for insects in order to show both its mode of operation and its beneficial features. The insect trap consists of a housing (1), FIG. 1, in which the power supply system (2), FIG. 1, and the circuit board (3) are mounted. The housing (1) is partially or completely made of suitable plastic, such as, for example, polyvinyl chloride, of metal or a combination thereof. The board (3) is powered by the power supply system (2) and generates the appropriate electric field. The field is a low current field of 2500V or even higher. The electric field is developed on a grid (4), made of suitable conductive materials. The integral grid (4) consists of three layers, where both the outer layer and the inner one have larger diametre holes, while the middle layer where the electric field is created has appropriate diametre holes to prevent insect passage.

(16) In an illustrative variant, the insect trap is fastened by using clamps (5), FIG. 2, which extend, either on one side of the housing (1), or on both, to fasten the trap on the door or window frame or in general on the opening to be mounted. At the bottom of the insect trap a collapsible screen (6) of any form is attached, which essentially prevents insect passage, but also allows users to enter and exit as desirable. In an alternative embodiment instead of a screen (6) any suitable curtain may be fitted, such as cabin curtains, air curtains or opening doors. Given that insects and especially mosquitoes are always trying to find the proper opening to enter a room, it is desirable that the holes of the screen (6) are smaller than the corresponding holes of the outer layers of the grid (4) so that they should be guided to it to pass through. The insect trap can be mounted even on existing screens (6).

(17) The insect trap can be mounted in the openings in other ways, too. It is therefore possible to create an insect trap of shorter length and consisting of two superimposed segments, FIG. 5. In this way it will be placed and supported in the frame only on one side, and when the user uses it he will deploy its superimposed segments, FIG. 6. In such a case the collapsible screen (6) will be placed in a second step and after the trap has been deployed.

(18) In another alternative variant of the invention, the insect trap may be of a sliding type, with one part of it inserting into the other, thereby making it smaller in size when closed. When the user wishes to use it, the user will slide it open, FIG. 7, to fully expand and cover the opening, and then place the screen (6) below it. This embodiment will be able to accommodate openings of different dimensions, since the deployment of the trap will be done to the extent necessary to cover the entire opening of the frame.

(19) In yet another alternative embodiment of the invention, the trap may be divided into four portions, FIG. 8, so that it collapses both upwards and to one side so that when closed it occupies one quarter of the total area. To do this, there are essentially four frames (11), each moving on drivers at the rear part thereof. Thus, the two frames (11) first deploy perpendicular to the ground, and then two more frames deploy in a superimposing manner to the first ones and parallel to the ground.

(20) Additionally, it is recommended to place a lamp (7) above or near the trap for insects to attract them. The lamp supply, preferably of low power consumption, can be made by the trap power supply, but can also be supplied separately. It goes without saying that, respectively, it may operate simultaneously with the trap or if it is desirable to operate independently of it.

(21) In a further alternative embodiment and additionally to the above, it is possible to place a tray (8), FIG. 3 at the bottom of the insect trap. This tray (8) contributes to the collection of insects killed by the field developed on the grid (4). Thus an insect that is killed in the field falls into the particular tray (8) and thus the user may collect all the insects at regular intervals and clean the tray (8). In an embodiment the tray (8) may be fully detachable, while in an alternative embodiment it may be simply opened on one side and allow the insects to be collected or absorbed by means of a broom. The tray (8) may further alternatively consist of two parts, of equal or different length, which are opened separately, FIG. 4.

(22) In a further alternative embodiment of the invention, the inventive insect trap may have a field intensity controller through which the field intensity is varied. This ensures that the trap will work as desirable, while not causing the usual, annoying noise from killing the insects that hit the grid (4).

(23) In another alternative embodiment, a battery (9) may be inserted inside the housing (1), ensuring that the trap operates even in the event of a power failure. This battery (9) will be able to operate in parallel with power from renewable sources, such as solar, using solar panels (12), as well as wind energy. This allows that the power supply is secured by the battery (9) when it is not possible to use renewables, the renewables charging the battery (9) when the trap is powered by them.

(24) In a further alternative embodiment of the invention the trap may be placed on exterior wall apertures by embedding it. In such a case, the trap operates without an additional screen (6), but has additional covers (10) on each side, FIG. 10, with internal insulation (16), that may be opened and which the user opens when the trap is to be used. This attracts mosquitoes that are killed by the electric field of the grid (4). This alternative could be used in areas such as camps and campings that are generally guarded. When the trap is not in use, the covers (10) remain closed and their insulation (16) contributes to the overall insulation of the building.

(25) In yet another alternative embodiment of the invention, the insect trap may have means for remotely activating and deactivating it using a remote control. Accordingly, in ways already known, it may be switched on and off, resulting in it not being constantly under voltage, and alternatively capable of communicating with state-of-the-art devices, such as phones and tablets, and activating by communicating with known technologies, such as WiFi and Bluetooth technology.

(26) In another variant of the invention, an array of multiple devices may be created to cover large openings, such as outdoor spaces or patios, which cannot be covered by one device. The trap array, FIG. 9, can be operated with a power supply system (2) and an electrical circuit board (3). The traps can be connected together using cables (13) and male and female plugs. In an alternative embodiment there may be only one power supply system (2), but each trap shall have its own circuit board (3).

(27) In another variant the insect trap may have a grid (4) externally on its side to further trap the insects. In fact, in cases where it is mounted in openings that have no overhead protection, it may have a cover (14), FIG. 11, which is supported by one or more brackets (15), which protect it from rain and generally weathering conditions. The cover (14) can be oval or any other suitable shape, enhancing the aesthetics of the device.

(28) In yet another variant the insect trap may be deployed in a sliding manner, FIG. 12, but the grid (4) is in the form of rolls (17), wrapped within the trap segments. The two grid rolls (17) deploy independently, one from bottom to top and the other from top to bottom, FIG. 13. The result of the above process is to create again a grid (4) in which the electric field is created.

(29) In a further embodiment of the device, the insect trap may have a processor (18), FIG. 1, and a transceiver (19), working with all known technologies, such as Bluetooth and Wifi, to communicate with advanced devices and transmit data on the number of insects killed by the trap grid (4). The measurement may be made by the change in the electric field of the grid (4), upon the impact of an insect. In this way a map and a picture of the insects and especially mosquitoes that are killed in areas where such traps are installed can be created electronically.

(30) It should be noted at this point that the invention was described with reference to illustrative examples of application, but not limited to. It is assumed that any change or modification in the shape, dimensions, morphology, materials used and components of construction and assembly, as long as they are not a new inventive step and do not contribute to the technical development of the already known, are considered embodied in the aims and intentions of the present invention.
