Description

[0001] The invention relates to a locking device which serves as an anti-intrusion lock, in particular for retrofitting to a window or door. The invention correspondingly also relates to a window or door which has at least one or more such locking device(s) or to which at least one or more such locking device(s) is/are retrofitted.

[0002] DE 20 2010 004 837 U1 discloses a locking unit for retrofitting to windows and doors as an additional anti-intrusion protection. Figure 5 in DE 20 2010 004 837 U1 shows a window comprising a window frame and a window sash which is pivotably fixed to the window frame, wherein three locking devices are fixed to the frame and serve to prevent the window from being opened. Each of the locking devices has a bar which does not protrude into the opening pivot range of the window sash in a first rotational position relative to a mount and does protrude into the opening pivot range of the window sash in a second rotational position. The bar can be arrested in each of the first rotational position and second rotational position of the pivot lever. The window sash is blocked from pivoting open when the bar protrudes into the opening pivot range of the window sash. DE 20 2010 004 837 U1 discloses a locking device according to the preamble of Claim 1.

[0003] In the locking device of German utility model 20 2010 004 837, a square in a bolt which is formed integrally with the bar has a 90° countersink which a 90° tip of a threaded pin engages, thus preventing the bar from being able to be moved out of a retracted position into its extended position. The threaded pin has a specific inner profile, similar to that of a rim lock, in order to be able to loosen the threaded pin only by using a special tool. The special tool actually makes loosening the threaded pin more difficult. In view of the fact that burglars generally enter a building from the outside by prying open the window or door, the inner profile for the special tool only becomes relevant once the burglar is already in the building. The additional requirement for a special tool does not therefore appear to substantially increase the use of the device, but does raise costs. Moreover, the requirement for a special tool to open the locking device in order to open the window can even be dangerous, namely when fire breaks out in the building and people wish to escape into the open via the window. If the special tool is not available, or a fear response in the people fleeing the fire prevents them from using the special tool appropriately, this escape route through the window is blocked.

[0004] US 7,537,250 B1 shows a child-proof lock for drawers and doors which has a base body and a locking element which is pivotably arranged on the base body and can retract into a cavity in the base body in one of two rotational positions.

[0005] DE 20 2015 104 749 U1 discloses a security device for a window or door, comprising a base body which can be fixed to the door frame or window frame, and a blocking body which is rotatably mounted on the base body.

[0006] It is an object of the present invention to specify a cost-effective and secure alternative to the locking unit of DE 20 2010 004 837 U1.

[0007] The object is solved by the subject-matter of Claim 1. Advantageous further developments follow from the dependent claims, the description and the figures.

[0008] The socket of the locking device has a bore. A bore is understood to mean not necessarily only an aperture produced by means of a drilling method but also cylindrical apertures which can be produced in other ways. The bore serves to mount and guide a bolt, in particular a cylindrical bolt of a pivot lever. The socket is attached to a frame, in particular a window frame or door frame, such as for example adhered, for example using a suitable and preferably liquid or pasty adhesive or using a preferably double-sided adhesive tape, and/or screwed, such as for example by means of at least one screw which is firmly anchored in the frame by the thread of its shaft, wherein the socket is then enclosed, in particular clamped, between the frame and the screw head of the at least one screw, and/or by means of a rivet connection which comprises at least one rivet, and/or by means of a plug connection or latch connection or other suitable connection. The lower side of the socket can in particular have a contact surface which is designed and in particular embodied for fixing to the frame or sash. The contact surface can abut the frame if the socket or locking device is attached to the frame, or can abut the sash if the socket or locking device is attached to the sash. The bore and/or bolt, or its central axes, are arranged parallel to and at a distance from the contact surface. The socket, such as for example at least a fixing portion of the socket, can have at least one bore for the at least one screw or rivet, through which the shaft of the at least one screw or rivet extends.

Preferably, two screws or rivets and two bores for the screws or rivets can be provided for fixing the socket. The socket or locking device is attached to the side of the frame which points into the interior of the building. The window frame or door frame often or in most cases likewise opens towards the inside of the building. If the door sash or window sash pivots towards the outside of the building when opening, the socket can be attached to the door sash or window sash, and the frame can block the pivot lever and therefore block the window sash or door sash from pivoting open, thus enabling the window or door to be prevented from being pried open.

[0009] The locking device has a pivot lever which has a locking bar and a bolt which protrudes from the locking bar, extends into the bore and has a longitudinal axis. The locking bar can for example be cuboid-shaped or can have another suitable shape. The bolt, which is in particular cylindrical, extends into the bore and in particular completely through the bore, which can be configured as a transit bore, and is guided by the bore such that it can be rotated and axially moved. The bolt is joined - in particular glued and/or either pressed or screwed - to the locking bar, such that it is rotationally and axially fixed, as a separate part. A bolt which is joined to the locking bar has the advantage that the pivot lever can be produced more cheaply and that the bolt can for example be produced from a different material to the locking bar, thus enabling a material to be used for the bolt which has a greater strength than the locking bar. If the bolt is embodied in one piece with the locking bar, there can be a relatively significant notch effect in particular where the locking bar transitions into the bolt, whence it may be expected that the bolt will break at the transition to the locking bar if an attempt is made to open the locking device by force. It is generally preferable for the bolt and the locking member to be formed from different materials, such as for example metals or metal alloys or plastics. The locking bar can for example be produced from an aluminium material, i.e. aluminium or an aluminium alloy, or from a plastic, such as for example fibre-reinforced plastic, and the bolt can for example be produced from an iron material, such as for example steel.

[0010] The pivot lever can have a first rotational position about the longitudinal axis and a second rotational position about the longitudinal axis in relation to the socket. The elongated locking bar, the longitudinal direction or longitudinal axis of which is transverse or perpendicular to the longitudinal axis of the bolt, can for example be pivoted about the longitudinal axis by substantially 90° in the second rotational position as compared to the first rotational position. In each of the first rotational position and second rotational position, the pivot lever can be moved relative to the socket between a retracted position and an extended position, in particular along the longitudinal axis of the bolt. The bore can serve as a longitudinal guide for the bolt for this purpose. In its retracted position, which it can assume in the first rotational position and second rotational position, the pivot lever is blocked from rotating about the longitudinal axis of the bolt, in particular in both rotational directions, by the socket. In its extended position, the pivot lever can be rotated about the longitudinal axis of the bolt between the first rotational position and the second rotational position; in particular, the socket cannot prevent the pivot lever from rotating when it is in its extended position. The bore in particular serves as a rotary bearing for the bolt during the pivoting or rotating movement of the pivot lever.

[0011] The invention is characterised by a spring which is adapted so as to act between the socket and the pivot lever such that the pivot lever is held in its retracted position by the spring, in particular when the pivot lever is in its first rotational position or second rotational position. In other words, the spring presses the pivot lever into the retracted position. This prevents the pivot lever from being able to be moved out of the retracted position into the extended position, for example by shaking the window or door, since the spring holds the pivot lever in the retracted position. In addition, the pivot lever can however be released simply, by being moved out of the retracted position into the extended position counter to the spring or by compressing the spring. This enables the locking device to be released, in a simple way and without using a special tool, at a position situated on the inside of the window or door, in particular when someone wishes to open the window or door. Secure protection against intrusion from the outside is however still provided.

[0012] The spring acts as a compression spring and is configured as a helical or spiral coiled spring. The compression spring is pressured when the pivot lever is moved out of the retracted position into the extended position.

[0013] The spring is supported at its first end on the socket and at its second end on the bolt or on a part which is joined, axially fixed, to the bolt. The part which is joined at least axially fixed, such as for example a retaining ring or grooved ring or a screw, can be fixed to the bolt on which the second end of the spring is supported. The part which is joined axially fixed is attached in the region of the free end of the bolt, i.e. the end of the bolt which protrudes from the locking bar. The shaft of a screw can for example be screwed into the end-facing side of the end of the bolt, wherein the spring can be supported on the screw head of the screw.

[0014] The spring can surround a portion of the bolt. The socket can for example have a portion, such as for example a bearing portion, through which the bore extends continuously (as a transit bore), wherein the locking bar protrudes on one side of the portion of the socket, and a portion of the bolt protrudes on the other side of the portion of the socket, wherein said portion of the bolt is surrounded by the spring or is arranged within the spring.

[0015] The spring can in particular be arranged or configured such that it is tensed when the pivot lever is moved out of its retracted position into its extended position. The spring is correspondingly relieved when the pivot lever is moved out of its extended position into its retracted position.

[0016] In advantageous embodiments, the socket can have an axial abutment surface, in particular the portion of the socket which has the bore or through which the bore extends, wherein the axial abutment surface at least partially surrounds the bore and/or is substantially perpendicular to the centre axis of the bore which corresponds substantially to the longitudinal axis of the bore. The locking bar can have a complementary axial abutment surface which abuts the axial abutment surface when the pivot lever is in its retracted position and is moved away from the axial abutment surface when the pivot lever is moved into its extended position. The bolt, which is substantially perpendicular, i.e. normal, to the complementary axial abutment surface, extends from the complementary axial abutment surface cylindrically towards its free end. This enables the bolt and therefore also the bore to be produced simply. By contrast, DE 20 2010 004 837 U1 shows a bolt which has a portion exhibiting a circular cross-section and a portion exhibiting a square cross-section. The bolt in accordance with the invention does not have the square cross- section, such that the bolt in accordance with the invention can be produced more simply.

[0017] The socket can have a rotational abutment surface, wherein the rotational abutment surface is arranged such that it blocks the pivot lever from rotating about the longitudinal axis, by a first complementary rotational abutment surface of the locking bar abutting against the rotational abutment surface when the pivot lever is in its first rotational position, and a second complementary rotational abutment surface of the locking bar abutting against the rotational abutment surface when the pivot lever is in its second rotational position.

[0018] The rotational abutment surface of the socket can in particular be substantially perpendicular to the axial abutment surface. The first complementary rotational abutment surface can for example be substantially perpendicular to the second complementary rotational abutment surface. The first complementary rotational abutment surface and/or the second complementary rotational abutment surface can each be formed by a flank of the locking bar.

[0019] The locking device can for example have a locking element. A first variant of a locking element can be arranged on the portion of the socket which has the bore or through which the bore extends. The locking element can be moved back and forth between a locking position - in which the locking element engages the bolt, in particular a cavity such as for example an annular groove which is formed on the bolt, such that the bolt and therefore the pivot lever is or can be prevented from moving out of the retracted position into the extended position - and a release position in which the engagement between the locking element and the bolt is released, thus enabling the bolt and therefore the pivot lever to be moved along the longitudinal axis. The locking element can for example be a screw, such as for example a threaded pin configured in accordance with DE 20 2010 004 837 U1. Alternatively, however, the locking element can be a spring-elastically mounted pin which in order to be released relative to the socket can be spring-elastically withdrawn from its engagement with the bolt and, when released, can be moved back into the bore in which the bolt is mounted, in particular into the cavity in the bolt, by the spring-elastic bearing. This can secure against it being unintentionally released, in addition to the spring which acts on the pivot lever, while getting by without a special tool, thus improving the options for people to escape the interior of the building through the window, as compared to the device of DE 20 2010 004 837 U1.

[0020] A second variant of the locking element comprises a sleeve-shaped locking element which has a slot, in particular a continuous slot, along its longitudinal axis, thus enabling the locking element to be fitted onto the bolt, and in particular onto the spring which is applied to the bolt, by a movement transverse to the longitudinal axis. The locking element can in particular be slid over the portion of the bolt which protrudes out of the bore and which is arranged, on the portion of the socket which has the bore, on the side which lies opposite the locking bar. When fitted, the locking element can be supported on the socket on the one hand, and on the other hand on the bolt or on a part which is joined, axially fixed, to the bolt, such as for example the aforementioned retaining ring or grooved ring or screw. The locking element can thus prevent the pivot lever from moving out of the retracted position into the extended position, since the sleeve-shaped locking element preferably cannot be compressed in its longitudinal direction. This embodiment of the locking element also allows the locking element to be released without using a special tool, by simply removing it again laterally from the bolt.

[0021] The locking device described here, in particular the locking device configured in accordance with the preamble, can also be embodied without the aforementioned spring which acts on the pivot lever but with one or more of the following aspects: - the cylindrical bolt which protrudes from the complementary axial abutment surface; - the joining connection between the bolt and the locking bar; and - one of the locking elements described here.

[0022] In one development, the invention relates to a window or door which comprises a frame and a sash, in particular a door leaf or window sash, which is pivotably fixed to the frame, wherein at least one locking device of the type claimed here can be fixed to the frame, wherein the locking bar does not protrude into the opening pivot range of the sash when the pivot lever is in its first rotational position, thus enabling the sash to pivot open, and wherein the locking bar does protrude into the opening pivot range of the sash when the pivot lever is in its second rotational position, thus blocking the sash from pivoting open. The one or more locking devices are preferably arranged at the locations on the frame at which they can most efficiently prevent the window or door from being pried open. As already mentioned further above, the locking device can be fixed to the window sash or door sash, wherein the locking bar is pressed against the frame, thus blocking the window sash or door sash from pivoting open, when an attempt is made to pivot it open.

[0023] The invention has been described on the basis of several embodiments and developments. In the following, an embodiment of the invention is described on the basis of figures. The features thus disclosed, individually and in any combination of features, advantageously develop the invention. There is shown:

Figure 4 a sleeve-shaped locking element for fitting onto a bolt portion of the pivot lever which protrudes out of the socket; and

Figure 5 a window, to which several locking devices in accordance with the invention have been attached.

[0024] As can best be seen from Figure 2, the locking device 1 has a socket 10 and a pivot lever 20 which in an extended axial position relative to the socket 10 can be pivoted about the longitudinal axis L between at least a first rotational position and a second rotational position, such as for example by about 90°. The socket 10 has a bearing portion and two fixing portions which are arranged laterally alongside the bearing portion. Alternatively, one fixing portion or more than two fixing portions, such as for example three or four fixing portions, can be provided on the socket 10. Generally, at least one or at least two fixing portions is/are provided. The bearing portion has a cylindrical bore 11 which extends along the longitudinal axis L and extends fully from one side of the bearing portion to the other side of the bearing portion. Each of the fixing portions has one or at least one bore 28, such as for example two, three or more bores 28, in which a screw - in particular a screw head -is or can be accommodated such that it can be countersunk, wherein the screw serves to fix the locking device 1 or socket 10 to the frame 3 of a window 2 or door. The central axes of the bores 28 are arranged perpendicular to the longitudinal axis L, i.e. to the central axis of a bolt 22 or the central axis of the bore 11, and can for example - but need not necessarily - intersect the longitudinal axis L or the central axis of the bolt 22 or bore 11, i.e. the central axes of the bores 28 can be arranged at a distance from the longitudinal axis L. As an alternative to or in addition to the bores 28 as shown in Figures 1 to 3, one or more bores for accommodating a screw, in particular for accommodating the screw head such that it is countersunk, can be provided on the socket 10, wherein said screw serves to fix the locking device 1 or socket 10 to the frame 3 of a window 2 or door. This at least one bore and/or its central axis can be arranged perpendicular to and at a distance from the longitudinal axis L and/or parallel to the axial abutment surface 12 and/or the rotational abutment surface 13. The fixing portion is arranged and/or clamped between the frame 3 or sash 4 and the head of the screw, the shaft of which comprises a threaded portion which is anchored in the frame 3 or sash 4, when the socket 10 is fixed to the frame 3 or sash 4. The bores 28 are perpendicular, i.e. normal, to the contact surface of the socket 10 for the frame 3 or sash 4. The contact surface is designed and configured to abut the frame 3 or sash 4 when the socket 10 is fixed to the frame 3 or sash 4. The central axis of the bore 11, or the longitudinal axis L, extends parallel to and at a distance from the contact surface.

[0025] The pivot lever 20 has a locking bar 21 which in this example is cuboid-shaped and in which a cylindrical bolt 22 is anchored, in particular pressed or screwed and/or adhered, as a separate part. The bolt 22 is therefore anchored in the locking bar 21 such that it is rotationally and axially fixed. The locking bar 21 is designed and embodied to form an abutment for the sash 4 or frame 3, in order to prevent the sash 4 from pivoting open when the locking bar 21 is in its second rotational position. The bolt 22 extends through the (transit) bore 11 and protrudes out of the bearing portion on the side of the bearing portion which lies opposite the locking bar 21. A spiral coiled spring 23 which acts as a compression spring surrounds the bolt 22, in particular the portion of the bolt 22 which protrudes out of the bore 11. The shaft of a screw 24 is screwed into the end-facing side of the free end of the bolt 22. The spring 23 is supported at one end on the socket 10 and at the other end on the screw head. The tensed spring 23 presses the pivot lever 20 into the retracted position (Figures 1 and 3), wherein the pivot lever 20 can be moved out of the retracted position into the extended position along the longitudinal axis L by the tension in the spring 23. In the retracted position, a complementary axial abutment surface 25 - from which the bolt 22 protrudes perpendicularly and cylindrically -abuts an axial abutment surface 12 of the socket 10. The axial abutment surface 12 surrounds the bore 11 and/or the bore 11 extends through the axial abutment surface 12. The axial abutment surface 12 is arranged on the side of the bearing portion of the socket 10 which faces the locking bar 21. The socket 10, in particular one of its fixing portions, has a rotational abutment surface 13 which is roughly perpendicular to the axial abutment surface 12. The locking bar 21 has a first complementary rotational abutment surface 26, which is arranged parallel to and at a distance from the longitudinal axis L, and a second complementary rotational abutment surface 27 which is arranged parallel to and at a distance from the longitudinal axis L. The first complementary rotational abutment surface 26 and the second complementary rotational abutment surface 27 are arranged roughly perpendicular to each other.

[0026] The rotational abutment surface 13 is arranged parallel to the longitudinal axis L and has a distance from the longitudinal axis L which is preferably only minimally larger than the first complementary rotational abutment surface 26 and the second complementary rotational abutment surface 27. The first complementary rotational abutment surface 26 and the second complementary rotational abutment surface 27 have roughly the same distance from the longitudinal axis L.

[0027] In Figure 1, which shows the pivot lever 20 in its first rotational position and in its retracted position, the rotational abutment surface 13 and the first complementary rotational abutment surface 26 point towards each other or lie opposite each other, wherein the surfaces 13, 26 can abut each other or there can be a slight gap between the surfaces 13, 26. When the elongated locking bar 21 is in its first rotational position, its longitudinal axis extends parallel or roughly parallel to the central axis of the bores 28, and when the elongated locking bar 21 is in its second rotational position, its longitudinal axis extends transverse or perpendicular to the central axis of the bores 28. When the elongated locking bar 21 is in its first rotational position, its longitudinal axis extends transverse or perpendicular to the central axis of the at least one bore which is provided, for accommodating the fixing screws, as an alternative to or in addition to the bores 28, and when the elongated locking bar 21 is in its second rotational position, its longitudinal axis extends parallel or roughly parallel to the central axis of said at least one alternatively or additionally provided bore. The socket 10, in particular the rotational abutment surface 13, prevents the pivot lever 20 from rotating about the longitudinal axis L relative to the socket 10, in particular by means of the first complementary rotational abutment surface 26, when the pivot lever 20 assumes its first rotational position and its retracted position. The position shown in Figure 1 is the position in which the window sash 4 (Figure 5) can be pivoted open.

[0028] In order to pivot the pivot lever 20 into the second rotational position (Figure 2), the pivot lever 20 is moved along the longitudinal axis L out of the retracted position into the extended position and, once in the extended position, pivoted about the longitudinal axis L relative to the socket 10, in this example by about 90°, into the second pivoted position.

[0029] The spring 23 presses the pivot lever 20 out of the extended position (Figure 2) back into the retracted position (Figure 3), wherein the pivot lever 20 is situated in its second rotational position. When the pivot lever 20 is in its second rotational position, the rotational abutment surface 13 and the second complementary rotational abutment surface 27 lie opposite each other or point towards each other, wherein the surfaces 13, 27 abut each other or are spaced from each other by a slight gap (Figure 3). The socket 10, in particular its rotational abutment surface 13, prevents the locking bar 21 from rotating, in particular by means of the second complementary rotational abutment surface 27, when the pivot lever 20 assumes the second rotational position in relation to the socket 10 and is in its retracted position. In the position shown in Figure 3, the locking bar 21 protrudes into the opening pivot range of the window sash 4, thus preventing the window sash 4 from pivoting open relative to the frame 3 (Figure 5). Alternatively, the locking bar 21 of the locking device which is fixed to the sash 4 engages behind the frame 3 and thus prevents the sash 4 from pivoting open.

[0030] Figure 4 shows a sleeve-shaped locking element which has a slot on one side which extends over the entire length of the sleeve-shaped locking element, wherein by means of the slot, the locking element can be laterally fitted, in particular snapped, onto the portion of the bolt 22 which protrudes out of the bearing portion. The locking element is then supported at one end on the socket 10, in particular the bearing portion, and at the other end on the screw head 24. This prevents the pivot lever 20 from being able to move along the longitudinal axis L out of the retracted position into the extended position. In order to move the pivot lever 20, the locking element is removed again beforehand.
