• the reference numeral 1 generally designates a mosquito net frame equipped with an alarm device according to the present invention.
• the frame 1 of the mosquito net 2 is constituted by a first and a second lateral posts 3, 4 and by an upper beam 5 inside which the screen 6 of the mosquito net 2 can be rolled up.
• the screen 6 is in fact wound, in an upward region, onto a roller which is provided with elastic roll-up means, not shown, and is connected, at the lower edge 6a, to a grip bar 7 which is adapted to pull the screen 6 vertically downward.
• the grip bar 7 moves between an upper position, which is raised and adjacent to the upper beam 5, and a lower position, which is lowered and adjacent to the bases 3a, 4a of the lateral posts 3, 4.
• the grip bar 7 is provided with two strips 8 which protrude from its profile, so that it can be easily moved with one's fingers, and has, along its lower edge 7a, a longitudinal brush 9 which is adapted to block to insects the gap that remains when the screen 6 of the mosquito net 2 is in the lowered position.
• Respective devices 10 for the detachable engagement of the grip bar 7 to said posts 3, 4 of the frame 1 are provided at the bases 3a, 4a.
• Two adjacent chambers 11, 12 are formed internally along each of the lateral posts 3, 4.
• the lateral edges 13 of the screen 6 can slide in the first chambers 11, while the second chambers 12 accommodate the elements that constitute the alarm device, generally designated by the reference numeral
• the second chamber 12 of the post 3 accommodates one or more emitter elements 15 which emit infrared optical beams and the second chamber 12 of the post 4 accommodates one or more receiver elements 16 which receive infrared optical beams.
• FIG. 3 illustrates the cross-sections of the first and second chambers 11 and 12 provided inside each post 3 and 4. Both the chambers 11 and 12 have a cross-section which is open at a shorter side 11a and 12a.
• the first chamber 11 is substantially rectangular and has two opposite brushes 18 which guide the screen 6 of the mosquito net 2 during its vertical sliding, and prevent the entry of foreign matter in the chamber 11.
• the brushes 18 are locked in opposite positions proximate to the open side 11a of the first chamber 11 by way of respective bases 18a inserted in seats 19 formed in the first chamber 11.
• Seats 19 are formed by respective longitudinal edges 20 which retain internally the bases 18a and prevent the escape of the brushes 18.
• the second chamber 12 has a contoured cross-section being open at one of its shorter sides, which is closed by a protective enclosure 21.
• the protective enclosure 21 is substantially C-shaped and can be fitted on, and removed from, the lateral posts 3 and 4 by snap action so as to allow rapid access to the elements contained in the chamber 12.
• the internal profile of the second chamber 12 is such as to define a first longitudinal guide 22 and a second longitudinal guide 23, which lie internally along the chamber 12.
• the guides 22 and 23 are arranged opposite and parallel to each other and transversely to the plane formed by the screen 6 of the mosquito net 2, being formed by longitudinal ribs 24 and 25.
• the guides 22, 23 accommodate the emitter elements 15 and the receiver elements 16 of the alarm device 14, which can be advantageously arranged in preset positions along the posts 3 and 4 and locked thereat by means of screws.
• the elements 15 and 16 respectively emit and receive infrared optical beams and are mushroom-shaped, so as to define a lower base 26 and an upper head 27 which are circular and are connected one another by a tubular portion 28. In this manner, the lower base 26 is accommodated in the first guides 22, while the upper head 27 is accommodated in the second guides 23.
• the elements 15 and 16 can also be accommodated in said guides 22 and 23 in the inverted position.
• the elements 15 and 16 are circuitally connected to electric batteries 17 which constitute the independent power supply of the alarm device 14.
• the batteries 17 are accommodated in compartments 29 located at the bases 3a and 4a of the two posts 3 and 4.
• Each compartment 29 is provided with an angular protective door 30 which in the closure position is arranged flush to the profile of the post 3 and 4 and does not alter its styling.
• Figure 2 illustrates a second embodiment of the present invention, in which the constructive details are designated by reference numerals increased by 100 with respect to those of the preceding embodiment.
• both the emitter elements and the receiver elements are accommodated in the post 103, while the lateral post 104, which is free and not occupied by the emitter or receiver elements, contains a band 130 of a material adapted to reflect the infrared optical beams produced by the emitter elements and to direct them toward the receiver elements.
• Figure 4 illustrates the detail of another embodiment, in which the constructive details are designated by reference numerals increased by 200 with respect to those of the first embodiment.
• each one of the lateral posts is constituted by the assembly of two separate profiled elements 232 and 233, each of which contains respectively the first and second chambers 211 and 212.
• the profiled elements 232 and 233 are joined by fixing screws 234 which ensure their stable coupling.
• the frame 1 according to the present invention and to above described embodiments thereof has three options for connection to the acoustic warning device.
• an acoustic warning device 300 is accommodated inside one post and connected by means of internal wires 301 to an emitter 302 for controlling the acoustic warning, which is also arranged inside the same post.
• Figure 8 illustrates an acoustic warning device 303, accommodated outside the frame 1 and connected by radio waves to the control emitter 304, which is internal to the post of the frame 1.
• Figure 9 illustrates an acoustic warning device 305, accommodated on the outside of the frame 1 and connected by means of internal and external wires 306a, 306b to the control emitter 307, which is arranged inside a post. It has thus been shown that the invention achieves the proposed aim and objects.
