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

Description

[0001] 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.

[0002] 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 doors.

[0003] 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 down inside the runner guides, which are, in turn, firmly screwed to the surrounding walls. When the slats are placed in position one on top of another the aperture is closed and an "armoured" wall is formed.

[0004] To break into a building with this type of blind would only be possible after many hours of work with heavy house-breaking equipment and a great deal of noise would be made. It is even difficult to perforate with bullets from an ordinary fire-arm. The present type of roller blinds may easily be substituted by our new safety blinds by means of the application of special runner guides. It is only necessary to pull out the blind, 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 - (see appended drawings)

[0005] 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 (figure 5, no. 23). The runner guides come in two types:

1st type: Figure 2 - no. 1:

[0006] This model is completely inserted into the wall and is used for new buildings and wherever it is easy to insert.

2nd type: Figure 2 - no. 2:

[0007] 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 (figure 3, no. 3, figures 8 & 9). They also have grooves for anti-vibration fillets, figure 5, no. 24).

- The pins (figure 2, no. 4), which are inserted into the runner guides can be installed in two different ways:

[0008] - A - They are simultaneously anchored to the steel rods and to the slats of the blinds (figure 2).

[0009] 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.

[0010] The head of the pin is protected by an antifriction 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, 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) is then 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)(figure 4, no. 22) which blocks all the pieces.

[0011] - B - By anchoring the pins just to the metal rods. (fig's 10 - 15).

[0012] - The pin (no. 25) is inserted into the alignment dowel (no 26) and then soldered to the metal 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 inserted into the slat (no. 10). After the pin protudes part no. 26 is fixed and the pin head (no. 30) is applied and soldered.

[0013] This system can also be applied to metal sheet roll-down shutters used in shops and store- houses, 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 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), dowels (no. 7) and pressure blocks (no. 8), illustrated in 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 (figure 3, nos. 3, 12, - figures 8 - 9). - To reinforce 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 ensure that the blind stops gently against the lintel-(figure 1, nos. 17, 18, 19, 20, 21, figures 8 - 9). - When the blind slats have been assembled they are aligned vertically and placed into position by the fixing of special plugs (figure 2, no. 11; figure 10, no. 26).

[0014] Now the slat cavities are injected with polyurethane foam or another product, which makes the slats more compact, gives protection from the cold and heat and helps to isolate the rooms from noise - (figure 13, no. 32).

[0015] 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 (figures 2 & 3, no's 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 electric motor may br applied to the rolls whereon the blind is wound.
