Description

[0001] The present invention relates to an arrangement comprising at least a frame, a sash and a device for preventing the sash from closing according to the preamble of claim 1.

[0002] A device to prevent a sash from closing serves, among other things, as a pinch protection measure. It is intended to prevent the sash, which may preferably be part of a door or window, from closing if, for example, a child's hand or finger is caught in a gap between the sash and the frame.

[0003] These anti-pinch devices are often mandatory in public buildings, for example in daycare centers or hospitals.

[0004] Furthermore, anti-pinch devices are becoming increasingly popular, as they protect pets, such as cats, from being trapped when the window is tilted. With a tilted window, the problem can arise that the pet fits into the gap between the sash and frame at the top, but doesn't quite reach the top and slips down inside. This leads to entrapment from which the pet often cannot free itself.

[0005] Devices for preventing a door from closing are known in the art. A disadvantage of these known devices is that they often have to be mounted in a specific position on the frame or door leaf, for example, in an upper area. This results in inflexible mounting options. Furthermore, the devices can often only be used for either right- or left-hinged doors according to the relevant DIN standard. This increases production costs.

[0006] There are also known devices that prevent pets from getting trapped. These mesh covers are attached to the side of the device and fold out when the sash is tilted. This is visually unappealing and does not prevent the sash from closing. Therefore, to achieve optimal protection, two different devices must be installed.

[0007] In contrast, the present invention is based on the objective of creating an arrangement with a device that can be attached at any height to an arrangement on both the right and left sides and thereby provides protection against a wing slamming shut and an animal being trapped.

[0008] This problem is solved by the arrangement comprising at least a frame, a sash, and a device for preventing the sash from closing, wherein the device comprises a locking means and an actuating means, wherein the locking means is configured to be attached to the frame and, in the attached state, to prevent the sash from closing in a locking position and, in a release position, to allow the sash to close, wherein the actuating means is configured to trigger a movement of the locking means from the release position to the locking position, wherein the locking means, in the state attached to the frame, is pivotable about a pivot axis, the pivot axis of the locking means extending in a horizontal direction. Embodiments of the invention are specified in the dependent claims.

[0009] A door or window frame is typically installed in a wall opening. The frame lines the opening on three sides: vertically, to the left and right of the sash when installed with the sash closed, and horizontally, connecting the side panels above the sash. It usually consists of at least three sections. The locking mechanism can be attached to either the vertical or horizontal sections of the frame. This allows for flexible adaptation to specific needs. In a daycare center, for example, the locking mechanism can be attached to the upper part of the vertical frame or to the horizontal section to prevent children from reaching it.In a hospital, for example, the device could be installed in a lower section of the vertical frame to allow disabled people, such as wheelchair users, to reach it, preferably the locking mechanism. Furthermore, it is possible to install the locking mechanism at a height that prevents a pet from slipping into the downward-tapering gap between the sash and frame when the sash is tilted.

[0010] The locking device can be pivoted around a pivot axis to move from a release position to a locking position. The locking device is thus pivoted around its pivot axis. In a release position, the locking device is positioned such that it does not protrude from the frame and does not obstruct the sash. In a locking position, the locking device protrudes from the frame and thus prevents the sash from closing.

[0011] It may be provided that the pivot axis of the locking device runs orthogonally to the pivot axis of the sash. The pivot axis of the sash runs vertically through the hinges of the door or window. The pivot axis of the locking device runs orthogonally to the pivot axis of the locking device and parallel to the horizontal area of ​​the frame.

[0012] The actuating device may be designed to be attached to the sash. The actuating device is designed to trigger the movement of the locking device from a release position to a locking position. This triggering occurs the moment the sash is moved from a closed state to a tilted or rotated state.

[0013] Three different states can be distinguished in this arrangement. The first state is that the wing is closed. The second state is that the wing has been rotated to fully open the arrangement. The third state is that the wing has been tilted to partially open the arrangement.

[0014] If the actuator is attached to the sash, it automatically follows the sash's movement. The sash's movement is transmitted to the actuator, eliminating the need for a separate trigger to activate it. The actuator must be attached to the sash in such a way that, when the sash is closed, it rests against or is located near the locking mechanism.

[0015] It may be provided that the actuating device is a fitting already present on the wing, for example part of a mushroom head locking mechanism.

[0016] It is important to clarify that, in addition to attaching the locking device to the frame and the operating device to the sash, a reversed attachment is also possible. A reversed attachment operates on the same principle. For the sake of clarity, the application explains the attachment of the locking device to the frame and the attachment of the operating device to the sash.

[0017] The actuating element may be designed to exert a magnetic force on the locking element. For this purpose, the actuating element may be a magnet or consist partly of a magnet. Correspondingly, the locking element may be made at least partially of a ferromagnetic material. When the wing is closed, if the actuating element is in contact with the locking element or in its immediate vicinity, the proximity being determined by the strength of the magnetic force, the actuating element exerts a force on the locking element. The locking element may consist at least partially of a ferromagnetic material, so that an attraction exists between the actuating element and the locking element. When the wing is rotated or tilted, the actuating element changes its position relative to the locking element compared to the closed state of the wing.This also changes the magnetic force acting on the locking device from the actuator. Due to this attraction, the locking device follows the actuator. The movement of the locking device is limited by its pivotable mounting on the frame. The locking device has only one degree of freedom: pivoting about its axis. This results in a change from the release position to the locking position of the locking device.

[0018] Beyond a certain point, determined by the dimensions of the locking device, the actuator no longer has direct or very close contact with it. The magnetic force then no longer acts on the locking device, or only to a limited extent. In addition to the magnetic force of the actuator, the force of gravity also acts on the locking device. Since the locking device moves in a circular path due to its pivoting axis, this causes the locking device to move independently into the locking position from the moment the actuator no longer has direct or close contact with it. This results in increased safety, as it prevents the locking device from failing to engage and thus prevents the protection from failing.

[0019] It is also possible for the actuating device to exert a spring force on the locking device. In addition to magnetic force, it is also conceivable that the movement of the locking device is triggered by a spring force. In this case, it is possible that the actuating device is pre-tensioned when the sash closes, and that the movement of the locking device is triggered by the release of this tension when the sash opens. It is also possible for the actuating device to be an integral part of the locking device.

[0020] The frame may be designed with a recess, in which the device is at least partially positioned when the sash is closed. The presence of a recess offers the advantage that the device can be installed almost invisibly between the sash and the frame. This is both aesthetically pleasing and a safety feature. Due to the device's low profile and its placement within the recess, it is protected from external forces.

[0021] The device may include a locking device, wherein the locking device is suitable and configured to hold the locking device in a horizontal position in the locking position. The locking device holds the locking device in a horizontal position. This offers the advantage that, when pivoted about the pivot axis of the locking device, it does not pivot beyond a defined point. It may be provided that the locking device is in a vertical position relative to a longitudinal direction of the locking device in the release position and in a horizontal position in the locking position.

[0022] It can be provided that the pivot axis of the locking device is offset from the center point of the locking device. This offers the advantage that the locking device does not pivot around a center point.

[0023] It may be provided that the blocking device is arranged in a vertical position parallel to the frame in a release position and, in a blocking position, projects at least partially beyond the frame in the direction of the wing in a horizontal position.

[0024] A projection beyond the frame towards the sash can preferably be achieved by offsetting the pivot axis of the locking device from its center point. This simply results in the outer radius of the locking device's outer edges not being identical for all edges. Therefore, the locking device can have a longer and a shorter side relative to the pivot axis. The longer side pivots towards the sash when moving from the release position to the locking position. The shorter side pivots within the frame, thus requiring less space.

[0025] It may be provided that the device is designed as a pinch guard, whereby in the blocking position of the blocking means a sufficiently large gap remains between the wing and the frame so as not to injure a human hand, while at the same time preventing an animal from slipping into the gap between the wing and the frame in a tilted position of the wing.

[0026] The locking device can be designed to be slidably mounted on the frame. A so-called floating mounting of the locking device allows for the transfer of large forces, which can occur when the sash closes unintentionally, to the locking device without causing damage. The forces are transferred to the frame via the locking device. Without the slidable mounting of the locking device, it is possible for the locking device to detach from the frame at its mounting point if the suddenly occurring forces become too great. A slidable mounting of the locking device, which may, for example, include a damping element, absorbs the force acting on the locking device.

[0027] Wing for a door or window, at least comprising an actuating means, wherein the actuating means is designed to trigger a movement of the blocking means from the release position to the blocking position.

[0028] Frame for a door or window, at least comprising a blocking means, wherein the blocking means is designed to be attached to the frame and, in the attached state, to prevent the closing of the sash in a blocking position and to allow the closing of the sash in a release position.

[0030] It is not necessary for an arrangement 1 according to the invention to have all the features described below. It is also possible for an arrangement 1 according to the invention to have only individual features of the embodiment described below.

[0031] In Fig. 1 Figure 1 shows the front view of an arrangement 1 according to the invention. Fig. 2 bis 4 Each shows a side view of arrangement 1 from different perspectives. Fig. 4 bis 6 show sectional views EE from Fig. 1 .

[0032] The arrangement 1 comprises a frame 2 and a sash 3. In the figures, the frame 2 and the sash 3 are shown as parts of a hinged door. The sash 3 of the hinged door is designed to pivot along a pivot axis defined by the hinges 6 of the hinged door. The hinged door shown in the figures is equipped with a tilt-and-turn mechanism. The tilt-and-turn mechanism allows the sash 3 to be both rotated and tilted. In addition to hinged doors, it is common for windows to have a sash 3 equipped with a tilt-and-turn mechanism. The functionality of the claimed arrangement 1 is identical for a window with a tilt-and-turn mechanism. The arrangement 1 can also be used on doors or windows that have only a rotation mechanism or only a tilt mechanism.

[0033] In the Fig. 2 Wing 3 is shown in a rotated position. In the Fig. 3 and 4Wing 3 is shown in a tilted position. Fig. 4 Arrangement 1 is shown with a closed wing 3. Fig. 5 shows arrangement 1 with a rotated wing 3 and Fig. 6 shows the arrangement with a tilted wing.

[0034] The arrangement 1 comprises at least one locking means 4 and one actuating means 5. The locking means 4 is designed to be attached to the frame 2 and, in the attached state, to prevent the closing of the sash 3 in a locking position and to allow the closing of the sash 3 in a release position. The actuating means 5 is designed to trigger a movement of the locking means 4 from the release position to the locking position. In the figures, the locking means 4 is attached to the frame 2 and is pivotable about a pivot axis that extends in a horizontal direction.

[0035] The Fig. 1 and 5Figure 1 shows arrangement 1 with a sash 3 in a closed position. The device for preventing the closing of the sash 3 is not activated. The blocking means 4 is arranged in a release position in a recess on the frame 2 and is therefore in Fig. 1 not visible.

[0036] The Fig. 2 and 6 Figure 1 shows arrangement 1 with a wing 3 in a rotated position. The device for preventing the closing of the wing 3 is activated. During the rotation of the wing 3, the actuating means 5 triggered the movement of the locking means 4. The locking means 4 is in a locking position.

[0037] The Fig. 3 , 4 and 7Figure 1 shows arrangement 1 with a wing 3 in a tilted position. The device for preventing the closing of the wing 3 is activated. The actuating means 5 triggered the movement of the locking means 4 during the rotation of the wing 3. The locking means 4 is in a locking position.

[0038] As in Fig. 7 As can be seen, the device can be mounted on both sides of the sash 3 or the frame 2. This is particularly advantageous if the device is intended to prevent pets from slipping inside. Mounting it on both sides protects the gap between the sash 3 and the frame 2 on both sides. If the device is only intended to prevent the sash 3 from being closed, it is sufficient to mount it on one side of the sash 3 or the frame 2.

[0039] In Fig. 4It is evident that the pivot axis of the locking device 4 is offset from the center point. The pivot axis of the locking device 4 lies at the pivotable mounting point 7 of the locking device 4 on the frame 2. This simply results in the outer radius of the outer edges of the locking device 4 not being identical for all edges. It is therefore possible that the locking device 4 has a longer and a shorter side with respect to the pivot axis. The longer side is pivoted towards the sash 3 when moving from the release position to the locking position. The shorter side pivots within the frame 2 and thus requires less space.

[0040] To close the sash 3 after it has been rotated or tilted, the locking device 4 is manually pivoted from the locking position to the release position. This is achieved by simply pivoting the locking device 4 into a vertical position, whereby the locking device 4 is pivoted about its mounting point 7. After pivoting into the release position, the mounting point 7 is located at the lower end of the locking device 4 when installed. The locking device may be designed to lock into place in the release position.
