Abstract
Description
- The present invention refers to anti-intrusion protection devices for the openings of the doors or windows or shop-windows, particularly refers to an extensible grate to protect the opening of windows and doors.
- There are known modular grates notes for protecting doors and windows including a series of parallel vertical uprights and almost equally spaced fixed to at least a couple of transversal bars whose ends are provided with fixed protrusions fit to be inserted into the posts of the windows and doors to be protected.
- These kinds of grates can be extended by inserting, between the fixed protrusions and the ends of the transversal bars, extension modules constituted by vertical uprights fixed to transversal rods connectable to the corresponding horizontal bars so as to extend the grate.
- The main drawback of these kinds of grates or grilles consists in that said modular grille are so-called "fixed-type" and that is the transversal bars of each grate are rigidly fixed to the vertical posts of the related window or door. Although some of said grates could be hinged to a post, in every case the grate width is predetermined because the fitting of one or more extension modules in order to entirely cover the opening to be protected.
- There are also extensible grates that are constituted by a series of vertical uprights to which connecting transversal bars are constrained by means of, for instance, a system of levers for making, with the transversal bars, a four-bar linkage allowing the grate to be "packaged" close to the door or window posts. Such grates have an expensive realization cost because mobile and "packageable" and therefore necessarily strengthened by additional elements fit inside the vertical uprights and made of, especially the mobile transversal bars, very expensive material, such as for instance hardened steel and carbonitrided steel.
- From US-A-5 657 809 a grate with telescopically extensionable transversal bars is known.
- The main purpose of the present invention is to propose a grate allowing the on site change of its dimensions and therefore the fitting to the opening of the windows and the doors to be protected without making at the factory grates made to measure.
- Another object is to propose a grate provided with size regulations both in height and in width by virtue of the uprights and the extensible transversal bars allowing the right grate assembling guaranteeing the coincidence of the lock with the uprights although the opening posts may be out of alignment.
- Further object is to propose a grate of quite cheap and highly safe and reliable.

- With reference to figures from 1 to 6,
numeral 1 indicates an extensible grate with ledge to protect the window or door openings essentially includingtransversal bars 2,vertical uprights 3, at least one 4 of which is external, aclosure 5,locking members 5a, extension means 7 and twoextension elements 8. - The
grate 1 is constituted by two shutters closed and hinged to the shoulders of an opening 10 of the related window or door. In the following it will be principally described only one shutter because the two shutters are equal and positioned lined up in their closing condition C, with the exception of the presence of only oneclosure 5 in the case of close shutters and whose external uprights almost interfere. - Each shutter has two parallel
transversal bars 2 to which a plurality of parallel and equallyspaced uprights 3 are perpendicularly welded and whose number depends on the opening to protect, for instance varying from 2 to 8. - Each shutter of the
grate 1 is rotatably fixed to a shoulder of theopening 10 in correspondence of the ends of thetransversal bars 2 by means of afirst hinge 6. - With particular reference to the figures from 15 to 17, the extension means 7 associated to the end of each
transversal bar 2 hinged to the opening 10 include afirst block 12 that is interposed between the end of said bar and thefirst hinge 6 and is constituted by aninternal portion 12a slidably housed inside thetransversal bar 2 and by ahollow portion 12b external to said bar. - The
first block 12 is provided with a plurality of threadedholes 13, engaged bycorresponding grub screw 14 fit to space theinternal portion 12a from aplate 15 fixed inside thetransversal bar 2 for instance by means ofwelded joints 42 or rivets. - The
internal portion 12a of theblock 12 has a throughhole 16 crossed bylocking means 17, for instance a screw, whose threaded end is fit in a corresponding threaded hole of theplate 15 and whosehead 17a locks thehinge 6 against thehollow portion 12b in such a way to constrain this latter to a predefined distance from thetransversal bar 2. - The
hinge 6 is provided withprotrusions 18 lying on the surface of thehinge 6 in front of thehollow portion 12b of thefirst block 12 and fit in this latter in order to avoid the mutual rotation between the block and said hinge. - With particular reference to the figures from 12 to 14, in correspondence of the remaining end of each transversal bar the extension means 7 are constituted besides by a
second block 20 that is interposed between the end of thetransversal bar 2 and the external upright 4 and that has a first plurality of threadedholes 21, engaged bycorresponding grub screws 22 fit to space thesecond block 20 from astop 23 fixed inside thetransversal bar 2, for instance by means ofwelded joints 43. - Furthermore, the
second block 20 has a plurality of throughholes 24 crossed by the rod of clampingscrews 25 whose threaded ends engage corresponding threaded holes carried out in thestop 23 and whoseheads 25a mate theinner wall 4a of the external upright 4 so fixing this latter to the relatedtransversal bar 2. - It is advantageous to underline that the extension means 7 are telescopically associated to each
transversal bars 2 in such a way to adjust the width of thegrate 1 to theopening 10 to be protected. - With particular reference to the figures 9-11, to each end of an external upright 4 of a
grate 1 shutter is slidably fixed theextension element 8 that is internally provided with a bushing 8a crossed by thelocking members 5a and is fixed to the external upright 4 by screw means 28 passing through aslot 29 carried out in the side wall of said upright. - The
locking members 5a are connected to theclosing 5, housed inside the external upright 4. Each locking members includes arod 30, which is axially positioned inside the external upright 4, and which is fixed to aspacer 31 in correspondence of its end. - To the free end of said spacer is screwed a
headless screw 32 to whose remaining end is screwed apawl 33 having an axial excursion by screwing or unscrewing said screw. - The pawl. 33 is provided with an axial threaded
hole 34 in which agrub screw 35 is engaged having atip 35a directed toward thepawl 33 and inserted into the pawl head in order to avoid its rotation whit respect to theheadless screw 32. - The installation of the
grate 1 provides the adjustment of the width and height grate dimensions by using and adjusting the extension means 7, associated to the transversal bars, and the adjustment of theextension elements 8 housed in the external uprights. - The operator regulates the length of the
transversal bars 2 by rotating, screwing or unscrewing, thegrub screws 14 whose free ends mate theplate 15 and determine the distance between this latter and thefirst block 12. After the adjustment, theprotrusions 18 of thehinge 6 are inserted in thehollow portion 12b of thefirst block 12 and thescrew 17 is screwed to theplate 15 locking thehinge 6 to thetransversal bar 2 by compressing thehead 17a of thecrew 17 against said hinge which cannot rotate because of the engagement between theprotrusions 18 and the inside edge of thehollow portion 12b of thefirst block 12. - In the same way, the distance of the
second block 20 from thestop 23 is adjusted by screwing/unscrewing thegrub screws 22, while the lock of thetransversal bar 2 to the external upright 4 is made by clamping thescrews 25 whose head compresses an inside wall of the external upright 4 against thesecond block 20. - The access to the heads of the
screws 25 andgrub screws 22 is allowed by means ofcorresponding holes screws 25. - The adjustment of each
locking members 5a is done by previously screwing theheadless screw 32 into thespacer 31 and fixing, for instance by means of adhesive, and then screwing or unscrewing thepawl 33 on theheadless screw 32 so causing respectively the shortening or the extension of the end of therelative rod 30. - The clamping of the
grub screw 35 to the end of theheadless screw 32 effects the rotation lock of thepawl 33. - The operator provides therefore to adjust each
extension element 8 of the relative external upright 4 by positioning at desired height said extension element and fixing this latter to the upright by tightening thescrew 28. - In the preferred embodiment, the
grate 1 is constituted by a couple of shutters in which anexternal uprights 4 only has theclosing 5 provided with ahook 47 suitable for hooking the upright 4 of the other shutter. - A variant of the
grate 1 is shown in figures 4 and 5 and provides the use of across-bar 9, upper and/or lower, whose ends are fixed to the shoulders of theopening 10 to be protected, for instance by means of a couple ofwedges 46. Each of saidcross-bar 9 is positioned at the outside of thegrate 1, nearly parallelly to thetransversal bars 2 so that thepawl 33 of thelocking members 5a is engaged in a related hole of thecross-bar 9 in correspondence of a closing condition C of thegrate 1. - In the figures 3 and 5, two variants of the
grate 1 are shown which is constituted by a couple of shutters having the sameexternal uprights 4, that is provided with theextension element 8 and the locking means 5a so that it is possible to install the couple of shutters with theexternal uprights 4 spaced. Said grate variant provides the use of a couple ofclosings 5, without thehook 47. - In particular the figure 5 shows a combination of the two preceding variants.
- Another variant of the
grate 1, shown in the figures from 6 to 8, provides the use of asecond hinge 11 interposed between thefirst hinge 6 and the peripheral upright 4 in such a way to allow 1 the opening of thegrate 1 at around 180° beyond the shoulder of the opening 10 in order to open thegrate 1 above possible casings external to said grate. - The
second hinge 11 has afirst plate 11a having both a series ofprotrusion 40 fit to engage the inside edge of thetransversal bar 2 in order to avoid the rotation of thesecond hinge 11, and acentral hole 41 crossed by the rod of ascrew 36 fit to engage with a firstsmall plate 38 fixed inside saidtransversal bar 2, for instance by means of welded joints or rivets. - The
second hinge 11 further provides asecond plate 11b having twoholes 41 crossed by the rods ofrelated screws 37 whose ends are engaged with a secondsmall plate 39, fixed by means of welded joints or rivets, in order to lock thesecond plate 11b to thetransversal bar 2. - It is also advantageous underlining that the
grate 1 can have another variant constituted by a grate suitable to protect theopening 10 of a door in which, as shown in figure 18 for instance, thetransversal bars 2 are three instead of two and are equally spaced. - During the installation of the
grate 1, it is advantageous underlining that the operator can screw thegrub screw 35 with thetip 35a directed toward the cross-bar of theopening 10 so that, in correspondence of the closing condition C of thegrate 1 and the activation of theclosing 5, so activating the blocking means 5a, thetip 35a marks the precise point in which it is necessary to make the housing hole of thepawl 33. - It is important to underline that using said grate it is possible to adjust the grate dimensions and also to compensate the skews of the
opening 10 by means of the asymmetrical and suitable adjustment of each single extension mean 7 orextension element 8 or locking means 5a. - For instance the
second block 20 has an axial dimension of 35 mm and therelative grub screws - The
first block 12 has varying axial dimensions, for instance, from 30 to 80 mm with regard to theopening 10 to be protected. - A further variant, shown in figure 19, provides the use of the
single shutter grate 1 in which theclosing 5 has astop 50, constituted by aplate 51, provided with twoholes 56 to which ahollow block 52 is fixed, this latter having aslot 53, in which thehook 47 is engaged, in the closing condition C. - Said
stop 50 provides besides afurther hole 54 through which ascrew 55 passes for fixing theplate 51 to the shoulder of theopening 10. Afurther screw 55 passes through theslot 53 to cooperate for fixing theplate 51 so completely compressing the head of thescrews 55 against the edge of the corresponding holes 56. - The
stop 50 allows to maintain spaced theexternal upright 4 from the shoulder of theopening 10 for allowing an easier opening of said grate and an easier installation and for avoiding the possible friction of theupright 4 against the shoulder of said opening. - For all the variants of the grate above described, the grate operational adjustments are the same described for the preferred embodiment or for the variant suitable to protect the doors.
- The main advantage of the present invention is to provide a grate allowing the adjustment during the installation of its dimensions in width and height and therefore the fitting to the opening of the windows and the doors to be protected, without carrying out grates to measure.
- Further advantage is to provide a grate fit to be assembled so guaranteeing the coincidence of the lock with the uprights although the posts of the opening to be protected may be out of alignment.
- Further advantage of the present invention is to provide a grate having a simple realization, high reliability and safety and easy installation.
