Technical field
[0001] The invention relates to a locking device of the type described in the claims.
Background
[0002] A moving element, a gate, door or window, for example, which can be swung, rotated
or displaced, often comprises a lock. The lock may consist of a striking plate, which
can be mounted in the frame, and a pin/latch which can be inserted in the striking
plate, thereby retaining the moving element. It is an advantage for the striking plate
to be adjustable so that the pin and striking plate can be adapted to the installation
and can engage without obstruction.
[0003] Such a device is disclosed in
US5118151, which shows a striking plate which, when 2 screws are loosened, can be adjusted
in the vertical direction. It will be an advantage, among other things, to provide
better adjustment facilities.
Summary
[0004] The object of the invention is to eliminate or reduce the disadvantages and deficiencies
of the art described and to provide further advantages. This is achieved by means
of the striking plate and adjusting elements described the examples and the claims.
[0005] In one example a striking plate is provided comprising a fist plate and a second
plate and adjustment means;
the first plate is provided with slots which enable it to be adjusted in a first direction;
the second plate is provided with serrations which allow gradual adjustment in a second
direction. For example, a striking plate can be provided which is flexible, strong,
reliable and easy to assemble. For example, one plate can be adjusted and continuously
afterwards adjusted to interact with the lock pin, whilst the other plate can be permanently
fastened.
[0006] In one example the striking plate comprises adjusting means. Adjusting means hold
together the second plate and the first plate. For example, the plates may be adjusted
in this manner, quickly assembled and retained with a small number of components.
[0007] In one example adjusting means hold together the second plate and the first plate
through holes and, which allow adjustment. For example, material is saved because
adjustment and retention are achieved with one and the same adjusting element. For
example, more efficient operation is achieved.
[0008] In one example the serrations in the second plate have a cross-section which passes
through the plate in a third direction. For example, good strength is achieved here
with compact dimensions.
[0009] In one example the second plate has adjusting holes which are partially created by
serrations. For example, the holes and the serrations are easily produced.
[0010] In one example the adjusting means interact with the slots in the first plate and
the serrations in the second plate. For example, the slots and serrations can be used
for achieving adjustment in two directions. For example, the two adjusting directions
may have different properties. For example, the adjusting means can be configured
for adjustment in two directions with stepless adjustment in a first direction and
gradual adjustment in a second direction.
[0011] In one example the adjusting means are sequential and, in operation, first allow
adjustment in a first direction and, in further operation, allow adjustment in both
a first and a second direction. For example, adjustment in a first direction can easily
be achieved without influencing the adjustment in a second direction.
[0012] In one example the first plate is a top plate and the second plate is a base plate,
where the base plate is configured to be secured permanently. For example, the first
plate is easily accessible for assembly and/or adjustment. For example, the second
plate can be permanently secured in a frame or on an interacting door (double door).
[0013] In one example slots are made in conjunction with holes in the first plate, and serrations
are made in conjunction with holes on the second plate. For example, the plates can
be adjusted and retained in this manner.
[0014] In one example the adjusting means are at least one adjusting element.
[0015] In one example the adjusting element interacts with the slots in the first plate
and the serrations in the second plate.
[0016] In one example the first plate has a hole with slots for receiving adjusting elements.
[0017] In one example the second plate has a hole with serrations for receiving adjusting
elements. For example, the striking plate can be assembled and adjusted quickly and
effectively.
[0018] In one example the first plate has at least one adjusting hole with slots.
[0019] In one example the second plate has at least one adjusting hole with serrations.
[0020] In one example an adjusting element is provided for the striking plate, comprising
- at least one actuating screw
- shoulders which allow stepless adjustment in a first direction
- serrations which allow gradual adjustment in a second direction. For example, a reliable
and strong component is obtained. For example, fast assembly and operation of adjustment
are achieved.
[0021] In one example an adjusting element is provided with shoulders which are 2 parallel
shoulders in a direction which allows adjustment in the first direction, and orthogonally
to it, 2 parallel sides with serrations which allow gradual adjustment in the second
direction. For example, fast, simple adjustment is achieved in one direction. For
example, strength is obtained in a second direction. For example, compact dimensions
are achieved.
[0022] In one example an adjusting element is provided in which the travel of the actuating
screw creates a first interval which allows adjustment in a first direction, whilst
adjustment in a second direction is locked and further travel creates a second interval,
which allows adjustment in both the first and the second direction. For example, simple,
fast actuation and adjustment in a first direction are achieved.
[0023] In one example a striking plate is used for a building component, in which the striking
plate can be adjusted.
[0024] In one example, adjusting elements are used for a building component in which the
striking plate can be adjusted.
[0025] In one example, adjusting means/adjusting elements are no higher than the thickness
of the plates of the striking plate, thereby providing a compact, low profile solution.
[0026] In one example, a striking plate with adjusting means is configured for adjustment
in at least 2 directions, where the adjusting means have at least 3 configurations:
- a clamped configuration in which the striking plate is unmovable.
- a first adjusting configuration, in which the striking plate can be adjusted in a
first direction.
- a second adjusting configuration in which the striking plate can be adjusted in both
a first direction and adjusted gradually in a second direction.
[0027] Exemplary embodiments of the invention can be combined with all the features and
examples mentioned. Generally speaking all designations of a unit should be interpreted
openly and understood as at least one unit/at least one occurrence, unless otherwise
explicitly indicated. Direction generally relates to an axis in which movement is
possible, and is not limited to a movement in one particular direction, unless otherwise
explicitly indicated.

Detailed description
[0029] The locking device may be a striking plate. The striking plate has a first direction
which is marked in Fig. 1 by A, a second direction which is marked in Fig. 1 by B,
and a third direction which is marked in Fig. 1 by C. The opening direction of the
lock will typically be the second direction (B). Fig. 1 shows an example of a striking
plate comprising a base plate (1), which can be permanently secured through holes
(2). The base plate can, for example, be fastened to a frame or a resisting element,
such as a double door. A top plate (3), which has at least one opening for a locking
pin (5), is mounted on the base plate (1). The base plate (1) and top plate (3) can
be assembled by means of adjusting elements (6). The top plate (3) has a hole (4)
which enables the top plate (3) to be displaced relative to the base plate (1) when
adjusting element (6) are used. The top plate (3) can be adjusted independently of
the assembled base plate (1).
[0030] An example of a top plate is shown in Fig. 2. Here the top plate is formed from 2
connected plates, a first top plate 3a and a second top plate 3b. The hole (4) may
be of varying size in the 2 plates 3a and 3b so that slots (8) are created which can
interact with adjustment elements (6). The uppermost top plate 3a has overlapping
holes (4) which, in a second direction, are wider than the hole in the second top
plate 3b.
[0031] The second top plate 3b has holes (4) which, in a second direction, are narrower
than the hole in the uppermost top plate 3a.
[0032] The lower hole (4) in the top plate (3b) creates countersunk slots (8) for adjusting
elements (6). The lower hole (4) in the top plate creates slots (8) for adjusting
elements (6). Slots (8) can be created in connection with holes (4). In the top plate
(3) at least one hole (4) in the first top plate (3a) and/or second top plate (3b)
may be rectangular. The top plate can interact with a locking pin.
[0033] Adjusting element (6) can be fastened and actuated with a screw (7). The screw (7)
can interact with a thread in a block (not shown). The block (not shown) with a thread
for the screw (7) may be located on the rear of/underneath the base plate (1). The
block may be larger in at least one direction than holes (9) in the base plate (1).
The adjusting element allows adjustment in a first direction and in a second direction
by the actuation of a single screw (7). The travel of the screw (7) influences the
adjusting element (6), thereby creating an interval which allows adjustment in a first
direction, whilst a second direction is locked and further travel creates a second
interval which allows adjustment in both the first and second directions. Adjustment
may therefore be carried out in a first direction without influencing the adjustment
in the second direction.
[0034] An example of an adjusting element is shown in Fig. 3. The adjusting element (6)
has shoulders (12) which interact with the slots (8) of the top plate and allow adjustment
in a first direction. The adjustment in the first direction may be stepless. The adjusting
element has serrations 11 which interact with serrations (10) in the base plate/second
plate (1). The serrations (10) and (11) allow gradual adjustment in a second direction.
Serrations (10) can be created together with holes (9). The teeth of the serrations
are perpendicular to a second direction. The serrations are parallel with a third
direction. This provides, among other things, a reliable, strong adjusting facility.
In Fig. 4 the cross-section of the serrations in a third direction is V-shaped. The
cross-section of the serrations is constant in the third direction. The cross-section
of the serrations (10) passes through the base plate (1). The serrations (10) run
in a third direction (C). Serrations (10) form a hole (9) in the plate (1). Serrations
(10) bring about the creation of an adjusting hole. Generally speaking, other suitable
serrations, teeth or recesses are also conceivable.
[0035] The surface on the serrations (10) which interact with adjusting means may be parallel
with the first direction, thereby ensuring good resistance to forced opening. The
serration surfaces on serrations (10) and/or (11) which absorb the stress from forced
opening may be formed at right angles to the direction of opening. The teeth of the
serrations may be displaced against the direction of opening so that they are better
able to absorb the stress from forced opening. The teeth of the serrations may be
formed at right angles to the direction of opening. The serrations may act as barbs
against the direction of opening.
[0036] The screw (7) can be loosened and allow adjustment of the top plate in a first direction
within a first interval. The first interval is determined by the thickness of the
base plate and/or the height of the serrations. When the first interval is exceeded
and the screw (7) is located in a second interval, the adjusting element can be displaced
in a third direction so that the serrations do not interact, thereby allowing adjustment
of the top plate (3) in a second direction. The adjusting element (6) has a sequential
function which first allows adjustment in a first direction and then also allows adjustment
in a second direction. Adjustment in the second direction may take place gradually.
Adjustment in the first direction may take place stepless. Adjustment in the first
direction may also be gradual.
[0037] The slots in the top plate (3) may, for example, be formed by forming the top plate
from 2 pieces, but the top plate may also be in one piece and other manufacturing
methods may be used to produce slots. In one example the top plate has no serrations.
In one example the top plate and base plate are assembled in the reverse manner. In
one example the top plate can be assembled concealed underneath the base plate. In
one example the adjusting element has a thread for the screw (7). In one example the
slots (8) are created in the base plate and the serrations (10) in the top plate.
In one example a spring can be used to actuate the adjusting element in the third
direction. In one example slots (8) may also be provided with small teeth.
[0038] The examples described can be used separately or in possible combinations. The invention
has been described with several examples, but is not limited by them. The examples
of the invention may be varied and modified in a number of ways, thus all embodiments
