Description

2264127 1 - A BOMBARDMENT-INHIBITING FACING The invention relates to a

bombardment-inhibiting facing of a surround of a door, a window or a wall element. The facing consists of security profiles which are arranged on the attack-endangered side of the fixed parts of the surround and which mutually overlap with their longitudinal edges. These cover both the surround and edge margins of the door, window or wall element.

In the case of a bombardment-inhibiting facing of this general type, which is known from German patent specification DE 37 11 936 C2, the security profiles are inserted into individual chambers in such a way that in each case two security profiles arranged in the same plane but in different chambers overlap with a security profile arranged in a different plane and in a further chamber. The chambers are formed by a common base profile and at least one closure profile. Whilst the base profile is connected to fixed parts of the surround, the closure profile can be superimposed perpendicular to its longitudinal extent onto the base profile.

The known facing makes it possible to fasten all the chambers, designed for the reception of the security profiles, by way of the base part thereof exclusively to fixed parts of a surround, so that swivvellable elements, such as door leaves and window casements are completely relieved of the weight of the chambers with the security profiles inserted therein. Also the number of profiles necessary for the formation of the chambers can be reduced in the individual profiles in each case form parts of several chambers. Finally, the detachability of the closure part of the chambers in the perpendicular direction to the longtidunal extent of the parts makes simple assembly possible, in which respect the facing can also be varied to form a different number of chambers.

HJO080293 - 2 The aforedescribed advantages presuppose, in the case of the known facing, the accommodation of the security profiles in chambers. However, the chambers themselves do not appreciably improve the bombardment-inhibiting effect and make the facing as a whole considerably more expensive.

Facings are also already generally known in which the accommodation of the security profiles in chambers is despenced with and the security profiles are, instead, fastened directly to limbs of outer and inner frames or leave or mullions. The above-described advantages of the facing known from DE 37 11 936 C2 are, however, not then achieved. For example in the case of a direct boarding over of the neighbouring limbs of an outer and inner frame or leaf with security profiles, between the mutually facing sides thereof a gap of specific width has to remain, which depends both upon the swivel radius and upon the thickness of the security profiles, so that the swivellability of the inner frame or leaf is ensured. To compensate for the weak point, arising therefrom of a bombardment-inhibiting facing, numerous solutions are already known, underlying which is the basic principle of avoiding a rectilinear gap course between security profiles and, instead, allowing the gap to extend more or less in a labyrith-like manner. Such overlaps can, however, only be effected in material thicknesses of the security prifiles which are smaller than the remaining thickness of the security profiles. Apart from that, intermeshing security profiles which are to be movable relative to one another require expensive and exacting manufacturing techniques and tight tolerances, and this also with respect to the positioning of the security profils on the surround.

An object of the invention is to design a facing, of the type described at the beginning hereof, in such a way that the security advantages, particularly by redson of an overlapping arrangement of several security profiles forming a profile combination in accordance with the construction HJO080293 - 3 known from DE 37 11 936 C2, are retained, but the manufacturing expenditure and complexity resulting by reason of an arrangement of the security profiles in chambers is avoided.

According to a first aspect, the invention provides a surround of a door, a window or a wall element having a bombardment- inhibiting facing consisting of security profiles which are arranged on the attack-endangered side of the fixed parts of the surround, which mutually overlap with their longitudinal edges and which cover both the surround and the edge region of the door, window or wall element, characterised in that per frame limb three security profiles are provided, two of which measured perpendicular to the plane of the door, window or wall element, respectively have a region of greater thickness and a region of smaller thickness annd are fastened to the surround in mirrorsymmetrical arrangement with neighbouring regions of smaller thickness, and in that parallel to the plane of the door, window or wall element the third security profile, which is substantially rectangular in cross-section, is inserted between the regions of greater thickness of the other security profiles so that as a whole a substantially rectangular cross-section is the result.

According to a second aspect, the invention provides a surround of a door, a window or a wall element having a bombardment-inhibiting facing consisting of security profiles which are arranged on the attackendanagered side of the fixed parts of the surround, which mutually overlap with their longitudinal edges and which cover both the surround and the edge region of the door, the window or the wall element, characterised in that per frame limb two security profiles are provided, which, measured perpendicular to the plane of the door, window or wall element, in each case have a region of greater thickness and a region of smaller thickness, in that the one security profile is fastened with its region of smaller thickness to HJO080293 - 4 the surround and in that the security profiles mutually overlap with their regions of smaller thickness in such a way that as a whole a substantially rectangular crosssection is the result.

Whether the facing consists of three or only two security profiles depends on the specific circumstances of use. Thus, a three-part embodiment is particularly advisable when, for example, a mullion which is adjoined by two sash frames with one frame limb each, or the middle limb of a fixed double-door frame which is adjoined by two doors with one door-leaf frame each, are to be covered in a bombardment-inhibiting manner. If, on the other hand, merely the frame of a door or of a window with associated outer frame of fixed frame of an adjoining panel as wall element is to be covered in a bombardment-inhibiting manner, the facing can also be composed of only two security profiles.

In both embodiments the facing does not need a sheathing in the form of expensive/complex chambers, which in the known arrangement additionally have the disadvantage that -the masking profiles thereof, which are clipped from the attack-endangered side onto the base profiles of the chambers perpendicular to their longitudinal extent, can be dismantled relatively easily with the consequence that the security profiles can easily be removed in an unauthorised manner from the chambers. Indeed, if the masking profiles are subsequently remounted, such sabotage might remain undiscovered for an unlimited period of time.

In the case of the facing in accordance with the invention consisting of three security profiles, the two security profiles with respective regions of greater thickness and of smaller thickness can be fastened from the attack-endangered side onto the fixed parts of the surround, for example by screws, and the fastening means be effectively masked by being covered by the third security profile.

HJO080293 - 5 - In the case of the-facing in accordance with the invention having only two security profiles, one of these can likewise be fastened by screws from the attack-endangered side onto the fixed parts of the surround and masking of the fastening means in this case can be effected by covering with the second security profile.

If the facing consists of three security profiles, the third (central) security profile overlapping the first two security profiles can be adjoined in a particularly advantageous manner to the overlapped security profiles by having integrally formed laterally at the regions of greater thickness of the first two security profiles respective ledge-shaped projections which each engages over an edge strip of the substantialy rectangular third security profile.

The connection can be accomplished by having the width of the substantially rectangular third profile, less the width of its edge strips, no greater than the free distance between the ledge-shaped projections of the outer two security profiles. Bearing these dimension conditions in mind, the rectangular security profile can be inserted obliquely until an edge strip thereof lies completely under a ledgeshaped projection of one of the outer profiles, then be swivelled until it rests upon the opposite security profile and thereupon be displaced perpendicular to its longitudinal axis towards this until the ledgeshaped projections of both security profiles engage over the edge margins of the central rectangular security profile at both sides thereof.

The establishment of a desirable force-locking connection in a direction perpendicular to the plane of the surround, between the differently thick security profiles on the one hand and the rectangular security profile on the other hand can be further simplified by having, on at least one longitunial side of the substantially rectangular security HJO080293 - 6 profile, a longitudinal groove into which the ledge-shaped projection of one of the other security profiles engages.

To ensure a central arrangement of the rectuangular security profile bwtween the other two security profiles and to complete the force-locking connection in a direction parallel to the plane of the surround, after the insertion of the rectangular security profile in the aforedescribed manner, the depth of penetration of the ledge-shaped projection into a longitudinal groove of the substantially rectangular security profile limited by press pins which can be driven into bores formed perpendicularly to the side surfaces of a longitudinal groove provided in the region of the greatest thickness of the respective outer security profile.

If the profile combination of the facing consists of only two security profiles, these can be connected in a s imple manner by having, integrally formed laterally onto the region of the greatest thickness of the first security profile, which is fastened to a fixed part of the surround, at least one ledge-shaped projection which engages over an edge strip of the second security profile.

When the aforesaid feature is provided, the overlapping second security profile can be displaced in a direction perpendicular to its longitudinal extent and laterally in a plane parallel to the surround in such a way that at least one edge strip of the first security profile for its part overlaps a ledge-shaped projection of the second security profile.

Also the establishment of a desirable force-locking connection in a direction perpendicular to the plane of the surround, between the two security profiles can be further simplified by providing at least one longitudinal groove in the first security profile into which a ledgeshaped projection of the second security profile will engage.

1 HJO080293 - 7 - To complete the fo:tce-locking connection also in the direction parallel to the plane of the surround, a ledgeshaped projecton of the second security profile can be retained in the longitudinal groove, provided for this purpose, of the first security profile by pins which can be driven into bores formed perpendicular to the side surfaces of the groove.

In order to be able to screw the security profiles that are to be fastened to the fixed parts of the surround on from the attack-endangered side, without in so doing having to countersink the screw heads into the security profiles, which would be difficult to accomplish, the mutually overlapping security profiles may advantageously enclose a hollow space in which the heads of the screws can be positioned.

The hollow space for the positioning of the screw heads can be achieved in a simple manner by designing the security profies butting against the fixed parts of the surround in a step-shaped manner on their side remote from the surround.

Finally, in some embodiments of the invention the security profiles may be bonded to one another and/or the facing formed therefrom may be bonded to the fixed parts of the surround.

An exemplified embodiment of each of the two types of bombardmentinhibiting facings in accordance with the invention is shown in crosssection in the drawings, in which:

Fig. 1 shows a rebate profile arranged between two limbs of one swivellable door or window frame each; and Fig. 2 shows a rebate profile arranged next to a limb or a single swivellable door or window frame.

HJ0080293 - 8 - The bombardment-inhibiting facing is, in the two illustrated embodiments, designated by reference numerals 1 or 2 respectively. The facing 1 in Fig. 1 comprises three security profiles 3, 4 and 5, while the facing 2 in Fig. 2 comprises two security profiles 6 and 7.

In Fig. 1 each of the security profiles 3 and 4 have a region 13 of greater thickness and a region 8 of smaller thickness and they are screwed onto a fixed part 10 of the surround in mirror-symmetrical arrangement with the regions 8 directed towards one another by means of screws 9, the fixed part 10 being designed in conventional manner as a rebate profile. The security profiles 3 and 4 mask both the fixed part 10 and respective conventionally designed contiguous limbs 11 of the surround of panels or panes 12, shown in fragmented manner, of swivellale doors or windows, and also edge regions of these panels 12.

The security profiles 3 and 4 are fastened to the fixed part 10 in such a way that they define, with the regions 13, a free space. The rectangular security profile 5 is positioned in this space and retained therein by a respective ledge-shaped profjection 14 integrally formed laterally on each region 13 engaging over an edge strip 15 of the security profile 5.

To enlarge the free clearance upon the insertion of the security profile 5, the latter is provided on one longitudinal side with a groove 16, into which the projection 14 of the region 13 of the security profile 4 lying opposite to it can be laterally inserted until the edge strip 15 on the opposite longitudinal side of the security profile 5 engages behind the projection 14 integrally formed laterally on the region 13 of the security profile 3, by the security profile 5 being displaced perpendicular to its longitudinal extent, then parallel to the plans of the surround, into central position bewteen the security profiles 3 and 4.

HJO080293 - 9 - The security profie 5 is fixed in this central position by press pins 17 being driven at intervals along the length of the facing 17 into bores which have been formed perpendicular to side surfaces of a groove defining the projection 14 in the security profile 4.

As a result of a step-handed design of the regions 8 on their sides remote from the surround, a hollow space 18 is created on that side of the security profile 5 which faces the surround, in which heads 19 of the screws 9 can be positioned in order to make possible a flush bearing of the security profile 5 onto parts of the regions 8 of the security profiles 3 and 4.

In Fig. 2 the security profiles 6 and 7 likewise have, in each case, a region 24 or 25 of greater thickness and a region 21 or 23 of smaller thickness. In this respect, however, only the first security profile 6 is fastened in its region 21, by means of screws 22, to a fixed part 20, which is designed in conventionaly manner as a rebate profile. The region 23 of the second security profile 7 covers the region 21 of the first security profile 6. Since the region 24 of the security profile 6 protrudes away from the surround and the region 25 of the security profile 7 protrudes towards the surround, the facing 2 with mutual overlapping of the regions 21 and 23 is completed rectangularly by the two security profiles 6 and 7.

Respective ledge-shaped projections 26 and 27, which are integrally formed laterally on the regions 21 and 24 of the first security profile 6 engages over respective edge strips 28 and 29 of the regions 25 and 23 respectively of the second security profile 7, whereby the latter is connected, in the perpendicular direction to the surround, in a forcelocking manner to the first security profile 6.

The facing 2 covers both the fixed part 20 of the surround edge strips of panels 30 (shown fragmented) and the limbs 31 HJO080293 - 10 of the frame of said panel, which limbs 31 are designed in the conventional manner. The facing 2 is held together in a direction parallel to the surround in a force-locking manner, in this exemplified embodiment, by press pins 32 which can be driven into bores which are formed perpendicular to side surfaces of a longitudinal groove 33 defined by the projection 27 in the security profile 6.

As a result of a step-shaped design of the region 21 of the security profile 6 on its side remote from the surround, a hollow space 34 remains between the regions 21 and 23 of the security profiles 6 and 7 in which space the heads 35 of the screws 22 can be positioned, without frustrating the proper interengagement of the security profiles 6 and 7.
