ANTI-BURGLARY SAFETY DEVICE FIXABLE TO ROLLER BLIND SLATS FOR WINDOWS AND DOORS

Abstract: The device makes a strong union between blind and wall by means of the application, to all kinds of roller blinds, of steel rods (6) with lateral pins (4), the heads of which are blocked inside the runner guides (1, 2), which are, in turn, strongly screwed into the surrounding walls.

Description: i D E S C R I P T I O N oT the Invention called ; H Anti-burglary aafet.y device fixable t roller blind slats for windows and doors " . Claasification : Section E Immobile constructions Class E.05 At present the various types of roller blinds for closing windows or doors just slide up and down by- means of side runner guides without actually being fixed to the walls; which means that.it is very easy for burgulars to break in. For the first time this invention achieves a strong union between blind, runner guides and walls, thus providing the best possible way of closing windows and doora. This takes place by means of the application of steel rods inside the slats; the ends of the steel rods are fixed into the side runner guides by means of special pins; the heads of these pins slide up and dourn inside the runner guides, W c are, in turn, firmly screwed to the surrounding walla. When the slats are placed in position one on top of another the aperture is closed and an "armoured" wall iβ formed. To break into a building with this type of blind would only be posaibla after many hours of work with heavy house-breaking equipment and a great deal of noise would be made. It is even difficult to per¬ forate with bullets from an ordinary fire-arm. The present type of roller blinds may easily be sub¬ stituted by our new safety blinds by means of the application of special runner guides. It is only necessary to pull out the blindj fix the special runner guides into the existing ones, screw them in and then insert the new blind. In new buildings the procedure is the same as that followed at the present. Working method - The special metal runner guides are fixed into the already existing ones or into specially prepared grooves by means of long screws placed at a distance of 15 cms. one from another, Table 3 f figure 5, no. 23. The runner guides come in two types: 1st type : Drawing Table 2 - figure 2 - no. 1, c5_i?^'i3£_? i i ! * ■ •__<" " - -___» afl .-_-_-_-_- i this model is completely inserted into the wall and la used for new buildings and wherever it is easy to insert, 2nd type : Drawing Table 2 - figure 2 - no. 2 - this model is used for insertion into metal U-type runner guides already fixed into the walls. - Both models have slots for bolts to block the rolling up of the blinds (Table 2, figure 3, nos; 3, 10, 12, Table 5, figures 8 & 9), They also have grooves for anti-vibration fillets (Table 3, figure 5, no. 24).- - The pins (Table 2, figure 2, no. 4), which are fixed into the runner guides can be installed in two different ways : -A- They are simultaneously anchored to tne steel rods and to the slats of the blind. Drawing Table 2, figure 2. A steel strap (no. 6) is inserted in the slat (no. 10) of the blind. The steel strap is the same length as the slat, it is curved and has a hole at each end; it is joined to the metal dowel no. 7; the pin no. 4 is inserted into the special hole. a asτπ ' uτs βHsiT ■ The head of the pin is protected by an anti-friction nylon bush (no. 5); the pressure block no. 8 is inserted into the small square hole no. 9. All these parts are then pushed inside the slat no. 10 until the opposite curved extremity of the metal strap no. 6 comes out on the other side of the slat. This operation is repeated, putting together the parts nos. 4, 5 f 6, 7| 8, on this side of the slat and everything is re-inserted in the slat so that the heads of the pins no. 4 protude to the same extent on both sides. On the inside of the slat the small metal block no. 8 isthen squashed by means of a punch; by doing this the metal block no, 8 becomes wider and a groove or slot is formed in the slat no. 10, (Table no. 3, figure no. 4, no, 22) which blocks all the pieces. -B- By anchoring the pins just to the metal rods. Drawing Tables 6-7-8. - The pin no. 25 i3 inserted into the alignment dow¬ el no. 26 and then soldered to the .αetal strap no. 28 at point no. 31. On the other side pin no. 29 is soldered without its head no. 30 so that it may be l inserted into the slat no. 10. After the pin pro- tudes part no. 26 is fixed and the pin head no. 30 is applied and soldered. This system can also be applied to metal sheet roll- down shutters used in shops and storehouses, simply ' by soldering the metal strap no. 28 and pins no. 25 directly onto the metal slats. This system can also be applied to grill-like roller blinds by soldering the pins, the heads of which are blocked and run up and down inside the lateral runner guides, to metal ' rods which are inserted into the parts of the blind -C- by directly anchoring the pins to the slats of the blinds with internal cavity. - Where the reinforcement of all the slats is superfluous, that is, where it is sufficent that k alternate slats be reinforced, it is possible for the slats to. be anchored to the side runner guides without the steel rods. - This is carried out with the use of pins no; 4, gowels no. 7 and pressure blocks no. 8, illustrated 5 in Table 2, figure 2, which are all, after being joined together, inserted into the slat no. 10 and then blocked by squashing with a punch as previously described in point -A-. - Bolts, blocking pins, alignment of the slats, filling of the slat cavities with synthetic resin or rubber cement :- - In order to ensure that the blinds cannot possibly be lifted, at the top and bottom and if necessary at other points, some of the slats have heavy bolts at both sides which penetrate into the side walls through the runner guides (drawings: Table 2, figure 3, nos. 3, 12, - Table .5, figures 8-9). - To re¬ inforce the blind even more against the possibility of it being pushed in from the outside the bottom slat has one or more bolts . which penetrate into the window sill or floor if it is a door. We have placed rubber buffers above the bolts in order to en¬ sure that the blind stops gently against the lintel- (drawings : Table 2, figure 1, nos, 17,18,19, 0,21, Table 5, figures 8-9). - When the blind slats have been assembled they are aligned vertically and placai into position by the fixing of special plugs (Table 2, figure 2, no. 11, Table 6, figure 10, no. 26). **s_j?=_*?=-?» Now the slat cavities are injected with polyouretan- ic foam or another product, wnich makes the slats more compact, gives protection from the cold and heat and helps to isolate the rooms from noise - (Table 7, figure 13, no; 3 )*- At this point the blind is rolled on to the normal rollers in the container above the window or door and is then inserted into the special runner guides- (Table 2, figures 2 & 3, nos, 1, 2). - As the blind is now heavier than before and to make it easier to lift the blind, any well-known reduction gear device or special eletric motor may applied to the rollers where the blind is wound round. • _.._s β τ τsβϊ*e * ι

Claims: C L A I S Definition of the object for wiiich protection is requested : "Anti-burglary safety device fixable to roller blind slats for windows and doors " At the present roller blinds for closing windows and doors slide through lateral runner guides without them being fixed to the surrounding walls. This system makes it very easy for burgulars to break into houses etc. The device invented has, as distinctive feature, the . application of steel rode to roller blinds, the extre= mities of which are fixed firmly to the side runner guides by pins, the heads of which, are closed and run up and down inside the runner guides, which are, in turn, firmly screwed to the surrounding walla. Therefore, protection is requested as follows, which is to be considered as a single unity of invention. 1.) The application, to the slats or parts of roller blinds for windows and doors, of steel rods.At each extremity the rods have pine with heads, which are inserted and fixed into the side runner guides, which 3 are screwed to the walls. 2,) The protection of the manuf cture and commercial!* zation of all the single essential parts of the nical device employed in the making of this ew' product. i These mechanical parts are now described hereunder, where we refer to the attached drawings : 1) - Metal gunner guide for holding and sliding the blinds up and down; this model is completely inserted into the wall (drawings: Table 2, figure 2, 5 no. 1, Table 4, figures 6-7 )• 2 ) Metal runner guide for holding and sliding the blinds up and down; this model is to be inserted in¬ to already existing runner guides (drawings: Table 2, figure 2, no. 2, Table 3, figures 4-5 ). 3_) Steel pin with head and stop-groove for fixing the blind slats to the runner guide with nylon anti¬ friction bush (drawings: Table 2, figure 2, nos^ 4, 5; Tables 3 - 4, figures 4, 5, 6, 7 ). 4) Strip of sheet steel curved at both ends, with 5 blocking holes, for reinforcing the blind slats internally (drawings: Table 2, figure 2, no. 6, to Tables3 - 4, figures 4, 5, 6, 7). 5) Metal dowel with relative expansion block (draw¬ ings: Table 2, figure 2, nos. 7, 8, 9, Table 3 - 4, figures 4, 5, 6, 7 ). 6) Bolt with applied spring and check-pin, hole and nylon bush for sliding by hand (Drawings: Table 2, figure 3, nos. 12, 13, 14, 15, 16, Table $ figures 8 - 9 ). 2.)
