Definitions

  • the present invention relates to a latching hook for a restraining device and a restraining device with a corresponding latching hook.
  • Sliding glass walls or similar sliding walls are used to open and close large building openings, such as a conservatory or a patio roof with side walls.
  • the sliding glass walls should be lockable in a closed position to prevent accidental opening and to provide some intrusion protection.
  • locking devices that block a sliding wall or a door leaf when closed.
  • Such locking devices are generally components that are visible from the outside and represent a weak point in terms of safety on the one hand and an aesthetic point on the other.
  • the DE 20 2013 000 236 U1 describes a locking device for a sliding door with a housing and a pivotably mounted locking hook, in which a recess with an upper longitudinal edge which is inclined to a longitudinal extension of the locking hook is formed, wherein the recess is penetrated by a pin, which in turn is longitudinally movable relative to the actuation of the locking hook is mounted to the housing on this.
  • the EP 2 476 828 A1 describes a locking device for a sliding sash of a sliding sash system, comprising a housing in which a locking hook is pivotably mounted, which is connected to an operating lever via which the locking hook can be moved into a locking and an unlocking position, with means in the housing for fixing the Locking hooks are arranged.
  • the present invention is based on the object of providing a burglar-resistant and easy-to-use mechanism for closing building openings with sliding walls.
  • the engagement of the latching hook with a counter-latching element in the event of manipulation or an attempt to break open, with an attempt being made to prize it open in the direction of the rail guide is advantageously designed to be self-reinforcing. Nevertheless, a simple actuation of the driver coupled to the hook in the vertical direction is sufficient to rotate the latching hook about the axis of rotation, the engagement being able to be released essentially without resistance and without a translational movement of the carriage.
  • the snap-in hook is therefore burglar-resistant at the same time and yet very easy and resistance-free to use.
  • the latching hook is coupled to a driver as an actuating element.
  • the driver can be fastened as a stud in a threaded hole made in the latching hook.
  • FIG. 1 1 shows a perspective view of a portion of a device 1 for closing building openings according to an embodiment.
  • the device 1 has a rail guide 2 as a base, on which a plurality of sliding walls are slidably arranged.
  • the embodiment shown is an example of sliding glass walls for opening and closing large building openings, such as a conservatory or a patio roof.
  • the device 1 can be transferred to other types of sliding walls or to other applications.
  • a carriage 4 is provided for displaceably guiding a first sliding wall 3 .
  • the carriage 4 is designed to be horizontally displaceable along the rail guide 2 , for example in the form of a roller carrier for a roller running on a rail 29 of the rail guide 2 .
  • Sliding walls of this type can be overlapped with one another by moving them in parallel in order to close the building opening open.
  • a carrier 5 is provided for horizontally force-transmitting entrainment of a second sliding wall 6 that can be displaced along the rail guide in parallel or on a second rail of the rail guide.
  • a horizontal force for displacement can also be applied to the driver 5 from the outside.
  • the driver 5 is coupled to the first sliding wall 3 here, for example. If the first sliding wall 3 is moved, it also takes the second sliding wall 6 with it through the driver 5 as soon as the driver reaches the second sliding wall 6, as in 2 recognizable and symbolized by the drawn movement arrows.
  • first sliding wall 3 is designed as a pedestrian leaf
  • second sliding wall 6 it would also be conceivable to anchor the second sliding wall 6 separately, so that the driver 5 acts as a stop.
  • a retaining device 7 for retaining the carriage 4 in a predetermined position along the rail guide 2 is provided on a foremost sliding wall, here the first sliding wall 3 .
  • the restraining device is thus able to slide 4 and thus the first sliding wall 3 to lock in a predetermined position, in particular in a position closing the building opening.
  • the driver 5 is additionally designed as an actuating part of the restraining device 7 that can be moved vertically relative to the carriage 4 . It is therefore force-transmitting in the horizontal direction, for example as in 2 designed to take along the second sliding wall 6, and movable in the vertical direction to actuate the retaining device 7, as indicated by the vertical double arrow in 1 symbolizes.
  • a driver 5 of a device 1 for closing building openings which is designed for horizontal force transmission, as a vertically movable actuating part of a retaining device 7, which is designed to retain a carriage 4 in a predetermined position along a rail guide 2 .
  • the driver 5 is formed, for example, with a central pin 21 which is coupled to the retaining device 7 so that it can move vertically.
  • a dampening casing 22 is provided around the pin 21, which also covers visible sections of the mechanism of the restraint device 7 to the outside.
  • the retaining device 7 has, for example, a movably mounted latching hook 8 which extends laterally beyond the sliding wall and which can be actuated by means of the driver 5 and is designed to engage with a stationary counter-latching element 9 .
  • the driver 5 is directly to the Coupled latching hook 8, but of course an indirect coupling would be conceivable.
  • the retaining device 7 By actuating the driver 5 in the vertical direction, the retaining device 7 can thus be detached from the counter-locking element.
  • the latch hook 8 can be lifted out of the latch as shown in 2 shown.
  • FIG 3 shows a schematic sectional view of a restraint device 7 according to an embodiment.
  • the latching hook 8 has a bearing bore 10 which is designed to accommodate a rotary axis 10, which is symbolized here simply by a dash-dot line.
  • the axis of rotation 10 is vertical by an offset 15 (see 4 ) to a locking portion 26 of the locking hook 8 is arranged offset. The kinematic effect of this offset is discussed below in relation to 4 explained in more detail.
  • the locking hook 8 is mounted in the retaining device 7 so that it can rotate about the axis of rotation 10 and is spring-biased with a spring 12 in one direction of rotation. In this way, the latching hook 8 remains in the latched position shown without being actuated and can be rotated counter to the spring preload.
  • a threaded hole 11 is provided at an end of the latching hook opposite the latching section 26 , which is provided for coupling the driver 5 .
  • the driver 5 preferably has a screw bolt which can be screwed into the threaded bore 11 . If the driver 5 coupled to the latching hook at the threaded hole 11 is pressed vertically downwards against the spring preload of the spring 12, the latching extension of the latching hook 8 is lifted from the latching shown here with the counter-latching element 9.
  • FIG. 4 shows an individual representation of a latching hook 8 according to an embodiment.
  • the latching hook 8 has a bearing bore designed to accommodate a rotary axis 10 and arranged approximately centrally on the latching hook 8 .
  • a latching section 26 of the latching hook 8 shown here on the left is narrower than a bearing section 27 shown here on the right.
  • the latching hook 8 has an undercut 13, which is designed for positive engagement with the counter-latching element 9.
  • a sloping engagement edge 14 is provided for engagement with the counter-locking element 9 .
  • the gripping edge 14 has a special course which is oriented obliquely to a longitudinal axis of the latching hook 8, in particular at a predetermined angle ⁇ within the gripping edge 14 tangentially, preferably at right angles to the radius, to the axis of rotation 10.
  • the angle ⁇ can, for example, be in the range of 10° to 45°, in particular 25° to 35°, preferably about 30°, and is particularly dependent on the size of the offset 15 by which the axis of rotation 10 is vertically offset from the gripping edge 14 .
  • the contour of the latching extension is designed to be self-reinforcing in the event of an opening force being applied in the latched state due to the oblique course, so that a burglary-resistant engagement with a counter-latching element 9 can be implemented.
  • figure 5 shows a perspective view of a partially assembled restraint device 7 without driver 5.
  • the latching hook 8 is mounted in a receptacle 19 of the retaining device 7 by means of a rotary axis 10 embodied here by way of example as a round bolt pressed into the receptacle 19 .
  • the driver 5 preferably has a threaded bolt as the pin 21 , in particular designed as a stud bolt, which is fastened in the threaded bore 11 .
  • a vertical connecting link 20 is provided in the receptacle, in which the pin 21 is guided with play to compensate for the rotation.
  • the driver 5 coupled to the retaining device 7, here directly to the latching hook 8 can be actuated from the outside for a substantially vertical movement approximately at the height of the axis of rotation 10, on which a horizontal component is negligible at small angles of rotation.
  • driver 5 is hidden here.
  • FIG. 6 shows a carriage 4 with a restraint device 7 coupled thereto in the open state.
  • the carriage 4 therefore has a coupling section 18 for coupling the restraining device 7 for horizontal force transmission.
  • the receptacle 19 of the restraining device 7 has a corresponding coupling section 28 which can be hung in a form-fitting manner with the coupling section 18 of the carriage.
  • the latching hook 8 can be rotated about the axis of rotation 10 by a substantially vertical movement of the driver 5 and thus, as in the position shown, can be unlocked by lifting the latching extension of the latching hook 8 .
  • the damping casing 22 of the pin 21 screwed into the threaded bore 11 covers the link 20 in any position of the pin 21 from the outside and is invisible. The entire mechanism of the restraint device 7 is thus advantageously concealed from the outside and cannot be seen.
  • the illustrated locked state is assumed automatically, for example, by releasing the driver 5 by the spring preload of the spring 12, which pushes the driver 5 upwards and the locking hook 8 counterclockwise rotates so that the locking portion 26 is pressed down.
  • the locking hook 8 thus engages with a counter-locking edge 16 which is at the same height as the locking hook 8 .
  • the appropriate height of the counter-locking edge 16 is set with a vertical extension 17 of the counter-locking element 9 .
  • a method for producing a device 1 for closing building openings can thus be carried out as follows.
  • a first step of the method consists in providing a carriage 4 designed to displaceably guide a sliding wall 3, a driver 5 designed for horizontal force transmission, for example for displacing the sliding wall 3 or for taking along a parallel displaceable further sliding wall 6, and a retaining device 7 for retaining the carriage 4.
  • a further step comprises the coupling of the restraining device 7 to the carriage 4.
  • a further step comprises the coupling of the driver 5 to the restraining device 7 as an actuating part of the restraining device 7 which can be moved vertically relative to the carriage 4.
  • the method can also include countersinking the counter-latching element 9 in a vertical side end profile 23 delimiting the device 1.
  • the counter-locking element 9 is anchored in the side end profile 23 in a form-fitting manner.
  • FIG. 8 shows a perspective view of the installation situation of a counter-locking element 9.
  • the locking hook 8 is arranged at a predetermined height relative to a rail 29 of the rail guide 5 . So that the counter-locking element 9 is arranged with its counter-locking edge 16 at the same height during assembly, the vertical extension 17 is also designed for contacting the rail 29 and its height is designed for the predetermined adjustment of the arrangement of the counter-locking edge 16 at the height of the locking hook 8.
  • the counter-locking element 9 is recognizable as being countersunk in a vertical side end profile 23 which laterally accommodates the first sliding wall 3 in a closed state and is anchored therein in a form-fitting manner.
  • the side end profile 23 has a receiving groove 25 for this purpose.
  • the counter-locking element 9 is inserted with the extension 17 downwards into the side closure profile 23 in the manner of a sliding block in a form-fitting manner until the extension 17 is completely accommodated therein.
  • the side end profile 23 is then placed on the rail guide 2 in the area of the first rail 29A.
  • the counter-locking element 9 is then moved downwards, in particular automatically by gravity, along the side end profile 23 until the extension 17 touches down on the rails 29 A and makes contact with them.
  • the counter-locking element 9 can then be fastened in the side end profile 23 by means of an additional fastening means, for example a clamping screw.
  • a manufacturing method can thus additionally include that the side end profile 23 is placed on a horizontal rail guide 2 guiding the carriage 4, with the latching hook 8 being arranged at a predetermined height relative to a rail 29 of the rail guide 2, and with the counter-latching element 9 having a Counter-locking edge 16 and a vertical extension 17 which is contacted for the predetermined adjustment of the arrangement of the counter-locking edge 16 at the height of the locking hook 8 with the rail 29.
  • the rail guide 5 has, purely by way of example, three parallel rails 29A, 29B, 29C.
  • the first sliding wall 3 with the carriage 4 and the retaining device 7 is arranged on the outermost rail 29A, which, for example, borders on the outside of a building (not shown here).
  • the rail profile 20 shows a typically rounded profile of the rails 29A, 29B, 29C, on which the rollers of the carriage 4 with a corresponding profile can run with little friction.
  • FIG. 9 shows a perspective overall view of a device 1 for closing a building opening 30 according to an embodiment.
  • three sliding walls namely the first sliding wall 3, and further or second sliding walls 6, 6' are arranged here between two lateral side end profiles 23, which can be attached to posts of a patio roof, for example, which are each on different rails at least on their underside 29 of a rail guide 2 run on their own slide 4. Additionally the sliding walls can also run on carriage 4 at the top.
  • the rail guide 2 is attached along the building opening 30 in which the carriages 4 of the sliding walls 2 are accommodated, so that the sliding walls 3, 6, 6' can be slid on the rail guide 2.
  • the sliding walls 3, 6, 6′ are dimensioned such that their height is equal to the height of the building opening 30 and their width is sufficient to completely close the building opening 30 with all the sliding walls 3, 6, 6′ arranged on the rail guide 2 by being arranged side by side .
  • the driver 5 can be designed in particular as a plastic stop with a damping plastic sheath.
  • Its pin can be designed as a stud bolt, in particular with a shoulder adjoining an external thread.
  • it can be an M5 thread with a 6 mm step.
  • the latching hook preferably has an undercut sloping by 30°, to which a bearing bore accommodating the axis of rotation 10 is offset upwards by the offset 15 .
  • the latching hook can be made of stainless steel.
  • the counter-locking element can in particular be designed as a die-cast closing piece which has an undercut that corresponds to the undercut of the locking hook, for example also with a 30° bevel so that the latching hook cannot be opened when it is inserted into the striker without external actuation and a burglar-resistant lock is provided.
  • the sliding wall 3 can have a guide rail accommodating the carriage 4 and the receptacle 19 of the retaining device 7 , in the case of a glass sliding wall in particular an H-rail, which is laterally closed off by the receptacle 19 .
  • the receptacle 19 of the retaining device 7 can in particular be embodied as an end part, also designed as a die-cast, into which the latching hook 8 is inserted laterally together with a spring cartridge that forms the spring 12 and is introduced into a bore below the latching hook 8 and fastened by pressing in a dowel pin that forms the axis of rotation 10 becomes.
  • the coupling section 18 of the carriage 4 and the coupling section 28 of the receptacle 19 can be designed as mutually corresponding barbs which provide a form-fitting, force-transmitting connection under tensile stress.
  • the carriage and the restraint device 7 can thus be introduced into the guide rail as a system which is clamped together and which, in the latched state, cannot be guided out of the guide rail even by pulling vigorously.
