[0001] The invention concerns a system for windows, doors and the like, comprising at least
one pawl, ratch and/or bolt and at least one striker plate adapted hereto, said pawl,
ratch and/or bolt is adapted for engagement in at least one recess in the striker
plate, said pawl, ratch and/or bolt during closing substantially having at least a
part of a front surface which has contact against or is placed at a short distance
to a first inner wall in the recess in the striker plate, see for example GB 2220700
A.
[0002] The invention further concerns a system for windows, doors and the like, comprising
a pasquil lock and at least one striker plate adapted hereto, said pasquil lock comprising
at least one pivotal pawl for engagement in at least one recess in the striker plate,
said pawl during closing substantially having at least a part of a front surface which
has contact against or is placed at a short distance to a first inner wall in the
recess in the striker plate.
[0003] The invention also concerns a pawl comprising one front and one rear surface substantially
parallel with each other, on which surfaces in the one end there is an axis of rotation
around which the pawl can turn.
[0004] For the closing of doors and windows, it is commonly known to use pawls, ratches
and/or bolts or pasquil locks with a striker plate adapted hereto, and where the pasquil
lock comprises two pawls disposed at equally great distance around and to a lock housing
for same which pawls by locking of the window make a turning movement into their pawl
guides down in the striker plate adapted hereto. Such a system provides for a positive
closing of a door/window, but has the drawback that when the window/door is closed,
it is possible by means of a crowbar or other tool to press this tool between the
fixed frame part and the movable part and thus get the pawl lifted out of engagement
with the striker plate.
[0005] The object of the present invention is thus to provide a system comprising a pawl,
ratch and/or bolt or pasquil lock whereby the risk of a break-in via the window or
the door is considerably reduced, in that the lock itself comprising striker plate,
pawl, ratch and/or bolt is configured in such a manner that it is difficult to force
these parts out of engagement with each other, and whereby the solution/burglar proofing
can be incorporated in already existing frames by an adaptation of the striker plate
and the pawl, ratch and/or bolt, and pasquil lock itself.
[0006] This object is achieved with a system of the kind disclosed in the introduction,
and also where the first inner wall comprises a first wall part and a second wall
part with a first and respectively second distance to the centre plane of the recess,
measured in relation to the first wall part, which first distance is less than the
second distance, and where the front surface of the pawl, ratch and/or bolt comprises
a pin/boss.
[0007] In the cases where the striker plate comprises at least two recesses disposed in
an axially-parallel manner with integrated level differences in the one wall, it is
also achieved that the window is secured against break-in while in the ventilation
position.
[0008] The way in which the system functions is thus that in the striker plate there is
provided an additional recess in that wall which faces towards the surface of the
pawl which it turns past during the closing. At its outer tip and facing towards the
recess in the wall of the striker plate, the pawl, ratch and/or bolt is provided with
a pin/boss which during the turning movement of the pawl, ratch and/or bolt is just
able to pass down into the striker plate as a consequence of the additional recess.
Relating to a pawl, ratch and/or bolt arrangement the movement is activated by a toothed
bar device, in that the pawl, ratch and/or bolt is going forward and backwards while
the pawl, ratch and/or bolt is making the said turning movement. When the pawl, ratch
and/or bolt or pasquil lock is thus in its locked position, this pin/boss has in its
turning movement moved past the recessed area and now lies below the level for that
part of the front surface of the striker plate which is not provided with the recess,
whereby the pin roughly speaking establishes a grip in its lower edge, and whereby
it is thus not possible or at least extremely difficult for the window/door to be
forced open.
[0009] By providing a system according to the invention and as disclosed in claim 3, the
most appropriate positioning of the pin/boss is achieved.
[0010] By providing a system according to the invention and as disclosed in claims 4 and
5, sensible dimensions and scaling of the size of the pin/boss are achieved.
[0011] By providing a system according to the invention and as disclosed in claim 6, a simple
method in which to provide the second wall part is achieved.
[0012] The invention also concerns a pawl as disclosed in the introduction, and also where
on the front surface and opposite the direction of rotation the pawl comprises a pin/boss.
This pawl can be expediently dimensioned and configured as disclosed in claim 8 and
9.
[0013] The invention will now be described in more detail with reference to the drawing,
where
- fig. 1
- shows a section through a frame with a striker plate and a window with pasquil lock
in the open position seen in two different situations,
- fig. 2
- shows the same as in fig. 1, but where the pasquil lock is locked down in the striker
plate,
- fig. 3
- shows a longitudinal section along the line III-III in fig. 2,
- fig. 4
- shows a detail view of striker plate and pawl seen in perspective from the rear,
- fig. 5
- shows the same as fig. 4 but seen from the front,
- fig. 6
- shows a second example embodiment of a striker plate according to the invention seen
in perspective.
[0014] Fig. 1 shows a system according to the invention placed in a window system comprising
a frame 20 in which the window 23 is placed, and where that part of the system 1 which
concerns the operation of the pasquil lock 2 is mounted. This can close against a
frame 19 in which the striker plate 3 is mounted. Fig. 1 shows two situations, i.e.
a position in which the window is open and stands at a certain distance from the frame
19, and a second situation where the window is closed almost fully against the frame
19, but without the pasquil lock 2 having been activated via its handle 15 for a closing
of the window, which does not take place until as shown in fig. 3, where the pawl
4 of the pasquil lock is in its closed position.
[0015] The system thus comprises a striker plate 3 mounted in the frame 19, said striker
plate comprising a recess 5 which is mainly rectangular in shape, and with a first
inner/front wall 6 which the pawl slides against. This first inner wall 6 is produced
following known principles, but is modified so that preferably by milling-out or by
moulding of the product there is provided a difference in level in said wall, whereby
a first wall part 7 and a second wall part 8 appears, which first wall part 7 has
a first distance to the centre plane of the recess 5 measured parallel with and in
relation to the first wall part 7 and the second wall part 8, which has a second distance
which is greater in relation to this centre plane. The striker plate 3 can also comprise
a further recess 24 for additional locking of the system when the window is in the
ventilation position. The recess 24 is axially parallel with the recess 5 and can
comprise the same modified inner wall 6 as specified in claim 6.
[0016] During the locking as shown in fig. 2, in its turning movement the pawl 4 of the
pasquil lock 2 now slides down into the bottom area of the recess 5, which pawl 4
on its front surface and facing towards the first inner wall 6 has a pin/boss 13 which
is allowed passage in the recess as a consequence of the second wall part 8, which
can be compared substantially with a recess in the first inner wall. When the window
is thus locked, this pin/boss 13 lies laterally with this second wall part 8, i.e.
in the area under the first wall part 7, and where the pin 13, which is in the shape
of a hook which stands at right-angles on its surface, establishes a grip in the lower
edge of this wall part, whereby the forcing open of the window is made difficult and,
in the cases where this succeeds, there will be visible signs.
[0017] Fig. 3 shows a section through the construction shown in fig. 2, and where the system
1 is illustrated in its full configuration, comprising a handle 15 which activates
a lock casing 21 which, via known means, is connected to a drawrod/pasquil rod 18,
which in turn is engaged laterally to the lock casing 21 in at least two bridge areas
16 where a controlling of the pawls 4 takes place via a pawl guide 22 comprising a
recess 17 in which the turning axis 14 of the pawl 4 slides, at the same time that
a turning movement of the pawl 4 is effected by activation of the drawrod/pasquil
rod. With this activation, the pawl 4 turns down in the striker plate which is configured
for this purpose, in that it slides in the area corresponding to the second wall part
8 in the recess 5 in the striker plate 3. At its outermost tip and facing towards
the second wall part, the pawl 4 is configured with a pin which is dimensioned in
such a manner that this can slide freely into the area of the second wall part, and
when the pawl 4 is in its bottom position, this pin 13 has gripping engagement in
under the end edge of the first wall part. Both of the striker plates for each their
pawls 4 are mounted in the window frame 19, while the handle itself and lock casing
21 with pasquil bar 18 are mounted in the frame 20.
[0018] The detailed principles of the striker plate 3 and pawls 4 will be illustrated with
reference to fig. 4 and 5, in that here it will be seen that the pawl 4, which is
produced substantially following known principles, comprises a curved part with a
front surface 12 and a rear surface 26 which are plane parallel, and where at the
one end there is a pin 13 on each of these surfaces which serves as axis of rotation
14 which is in engagement with the recess 17 in the bridge 16, and where opposite
this there is provided a boss 13 which has a height of approx. 2 mm in relation to
the surface. The remaining dimensions, i.e. here the breadth and the length, do not
exceed the dimensions of the length of the second wall part 8 measured parallel with
the longitudinal axis of the centre plane 11 of the recess.
[0019] The striker plate 3 is similarly produced following known principles, but where in
the front wall, the first inner wall 6, a difference in level is provided so that
a first wall part 7 and a second wall part 8 are formed, where the difference in the
distance to the centre plane of the recess and to the first wall part 7 in relation
to the second wall part 8 is approx. 2-3 mm. The difference between the two distances
is thus substantially the same as the height of the pin/boss 13.
[0020] When the pawl 4 is closed, this will slide with its pin along the second wall part
and, when it is deepest down, its position will be lying under the first wall part
7.
[0021] Fig. 6 shows a second example embodiment of a striker plate 3, where this comprises
a recess 5 following known principles in the same manner as otherwise described above,
and where the wall of this is also provided with a difference in level in the first
inner wall 6 in the formation of a first wall part 7 and a second wall part 8. The
difference in level could also be formed by the welding of a mass on the first inner
wall 6, so that again there is provided a first wall part 7 and a second wall part
8. The advantage of effecting a milling-out to provide a difference in wall level
is that the system can thus make use of the known principles, in that in such a case
a milling-out is effected in the mounted striker plate, and where the pawl, which
is easy to replace, is replaced with the object of mounting the pawl with the unique
pin/boss 13 according to the invention.
[0022] As a second possibility, both the pawl and striker plate in an existing window system
can be replaced with a type according to the present invention, whereby the window
is upgraded in a simple manner. Moreover, the striker plate can be produced in fibre-reinforced
plastic material.
