Abstract

An assembly with a panel (6) , such as a door or a window, which is rotatable relative to a frame (5) and a security device comprises an opening (13) made in the frame or panel (6) and a projection (11) which is fixed at the other thereof and in the closed position of the panel extends into said opening (13). The assembly comprises at least one plate (2) with a positioning hole (7) into which the projection (11) fits, which plate is fixed to the panel or frame. The projection can have a widened base (12) which is hooked behind the plate (2). <IMAGE>

Description

The invention is related to a hinge set according to the preamble of claim 1.
Such a hinge set is disclosed in FR-A-964465. The lugs thereof are permanently connected to the corresponding leaf, such as by means of welding, riveting, pressing etcetera.
The disadvantage of this prior art set is that it cannot be applied for purposes wherein no lugs are required. Having regard to the fact that the lugs are permanently connected, they cannot be removed.
The object of the invention is to provide a hinge set of the type referred to before which is more flexible in use, and which allows the removal or application of lugs in question, dependent on practical circumstances.
This object is achieved in that at least one of the leaves has, at its side facing away from the other leaf, a recessed area around the auxiliary opening, in such a way that the lug with the widening can be hooked behind said at least one of the leave in the recessed area thereof at the side facing away from the other leaf.
The fitted position, i.e. the position in which one leaf of the hinge is fixed to a panel, and the other leaf to a frame, may be unsecured or secured, as desired. In the first case, the security lug is dispensed with, and in the second case it is simply inserted beforehand with the widening behind the leaf in question, and screwed down together with that leaf.
The hinge set can be in the form of a butt hinge or lift-off hinge. The advantage in that case is that the butt hinge or lift-off hinge is universal and that the security lug can be fitted at the same time without extra time and effort. Moreover, the lug fitted in this way is very stable; it is wedged firmly with its relatively large widening between the leaf and the frame. Another great advantage is that the lug is virtually impossible to remove; to remove it, the leaf would actually have to be detached completely, which is time-consuming and causes noticeable damage.
The pin preferably fits tightly into the auxiliary openings. Such a tight fit further benefits the stability.
In addition, the leaf provided with a recessed area can have at its side facing the other leaf an elevated area surrounding the auxiliary opening. In the closed position of the panel, said elevated area rests virtually against the other leaf. The advantage of this is that the gap between the two leaves is retained, even if the hinge pin is removed in an attempt at forcing. This means that the gap opposite, which lies near the panel closure or panel lock cannot easily be made larger, so that inserting a jemmy there becomes more difficult.
The leaves protect the underlying wood material of frame and panel from giving way as a result of the great forces exerted on the security lug during any attempt at forcing.
The invention will be explained in greater detail below with reference to a number of exemplary embodiments shown in the figures.
Figure 1 shows an assembly according to the invention, with a hinge.
Figure 2 shows a butt hinge according to the invention.
Figures 3 - 6 show alternative embodiments.
The butt hinge according to the invention shown in Figures 1 and 2 comprises two leaves 1, 2, which interact hingedly in the usual manner by means of hinge pin 3. The leaves 1, 2 are fixed by means of screws 4 respectively to a fixed part, such as a frame 5, and a moving part, such as a door, shutter, window and the like 6.
According to the invention, holes 7, 8 are provided in the leaves 1, 2. Hole 7 is situated in the centre of the dimpled part 9 of the leaves 1. It is also possible for both holes 7, 8 to be dimpled.
During the fitting of leaf 1 on the frame 5 the lug, which is indicated in its entirety by 11, is placed in the hole 7 of leaf 1 in such a way that its widened base 12 remains hooked behind said leaf. When the leaf 1 is being screwed down on the frame 5, the lug 11 with its base 12 is consequently sturdily wedged in position. Of course, the lug can also be fixed on the door or the window 6. It is clear that, if desired, the lug 11 could also be fixed in the recessed part 10 of the leaf 2.
The base 12 is a cylindrical shape which fits tightly into the correspondingly shaped recess 33 in the dimpled part.
In the closed position of the panel 6 the dimpled part 9 rests virtually against the opposite leaf 1. The result of this is that the gap 34 cannot be reduced, not even if the hinge pin 3 is removed. The gap 35 situated opposite consequently cannot be increased at the expense of gap 34 if any attempt at forcing is made (when hinge pin 3 is removed). This makes the insertion of, for example, a jemmy extremely difficult, so that forcing of the panel is tricky.
A hole 13 is made in door or window 6, concentrically relative to the hole 8 in the leaf 2, for accommodating the lug 11 in the closed position of door or window 6.
In the embodiment of Figure 3, a lug 14 which, in addition to a widened base 12, has an external screw thread 15 is used. This screw thread 15 fits into a corresponding threaded hole 16 in leaf 17 of a butt hinge.
In the embodiment of Figure 4, a lug 19 which is integral with a wood screw 20 is used. Said wood screw 20 is screwed into the panel or frame 21, while the lug 19 itself projects through a correspondingly shaped hole 22 in the leaf 23 of a butt hinge.
In Figure 5, a lug 24 which has a through-opening 25 with a step 26 is used. The head of the wood screw 27, which is screwed into panel or frame 28, rests on the step 26. The lug 24 is accommodated in the hole 22 of leaf 23 of a butt hinge.
In the embodiment of Figure 6, the lug 29 is in the form of a steel pin which is known per se, and is also called a burglarproof bolt. This pin 29 has a part with a number of barbed ribs 30, which part is driven into a previously drilled hole 31 in the frame or panel 32. The steel pin 29 projects through a hole 22 of the leaf 23 of a butt hinge.
In the embodiments of Figures 3 - 6, the security lug is also hooked with its base 12 behind the corresponding plate 17, 23 respectively.
The known pin 29 or burglarproof bolt works much better in this way: it is not only well protected against forcing attempts by the leaf 23, but is also retained well by it in the lateral direction.
In Figures 3 - 6, the other leaf (not shown) is provided with a corresponding hole, as shown in Figures 1 and 2, in which the lug 14, 19, 24, 29 is accommodated when the panel concerned is closed.
