Description

[0001] The invention relates to a fitting arrangement for a window, a door or the like for actuating a parking brake with a locking element that can be driven by a drive rod and moved between two end positions, and with a transmission element that can be arranged in a rotationally fixed manner on an actuating shaft of the parking brake, wherein the locking element has a first coupling section and the transmission element has a second coupling section.

[0002] Such a fitting arrangement is known, for example, from WO 2005 / 080 723 A1.

[0003] Parking brakes for windows and doors are generally well known. They serve to hold the open sash in any position relative to the frame. The purpose is to activate the parking brake by turning the handle. To activate the parking brake, the actuating shaft must be rotated. The coupling sections convert the linear movement of the drive rod into a rotary movement of the actuating shaft. In the solution described above, the coupling sections are always engaged with each other. This greatly limits the travel of the drive rod.

[0004] The object of the present invention is therefore to further develop a fitting arrangement of the type mentioned at the outset in such a way that, on the one hand, the actuation of the parking brake is ensured and, on the other hand, the stroke of the drive rod is not limited by the parking brake.

[0005] This object is achieved according to the invention by a fitting arrangement for a window, a door or the like for actuating a parking brake, comprising a locking element that can be driven by a drive rod and moved between two end positions, and comprising a transmission element that can be arranged in a rotationally fixed manner on an actuating shaft of the parking brake, wherein the locking element has a first coupling section and the transmission element has a second coupling section, and wherein the coupling sections can be coupled to transmit the movement of the locking element to the transmission element and are decoupled in at least one end position of the locking element. Depending on the position of the locking element, the two coupling sections are thus coupled or decoupled. The locking element can therefore execute a greater stroke than in the prior art, or stroke compensation elements can be dispensed with.In particular, it can be provided that the parking brake is only actuated in a middle stroke range of the locking element.

[0006] Particular advantages arise when the coupling sections are each designed as a toothed arrangement. In particular, the coupling sections can be designed as a pinion section or a rack section. Coupling sections designed in this way can be easily engaged and disengaged with one another.

[0007] A particularly simple design is achieved when one of the coupling sections is designed as a tooth and the other coupling section as a tooth gap. For example, a tooth can be formed on the locking element and a tooth gap on the transmission element. During a movement of the locking element, for example upwards, the tooth can engage with the tooth gap and thereby carry the transmission element with it, thereby rotating the actuating shaft to activate the parking brake. If the locking element is subsequently moved further, the tooth disengages from the tooth gap.

[0008] The reliability of the parking brake can be improved if a reverse rotation lock is incorporated into the locking element, preventing accidental release of the parking brake. For example, the tooth that is no longer engaged with the tooth gap can interact with a stop on the transmission element, thus preventing the actuating shaft from rotating backward and subsequently releasing the parking brake. Only when the locking element is moved downward again and the tooth is engaged with the tooth gap is the transmission element, and thus the actuating shaft, permitted to move to release the parking brake.

[0009] Further advantages arise, particularly when the sash is closed, if a locking piece is provided into which the locking element can engage in a locking or braking position. This allows a sash, for example, to be locked to a frame in an upper corner area. Additionally, when the locking element is fully extended, the parking brake is activated. A sash is thus doubly secured. Furthermore, a locking pin can be arranged on the drive rod, which also engages a locking piece, thus creating an additional locking position.

[0010] It is particularly preferred if the locking element can execute a stroke of at least 15 mm, preferably at least 18 mm. This ensures that the locking element engages with a corresponding locking piece. Even a larger upper rebate gap between the sash and the fixed frame can be bridged by the locking element with such a stroke.

[0011] Furthermore, a housing may be provided in which the transmission element and / or the actuating shaft is / are mounted or can be mounted. The housing may, for example, be designed to be received in a fitting groove.

[0012] The assembly of the fitting assembly can be simplified if the housing is constructed in two parts. This allows the transmission element, if necessary, to be inserted into one housing part together with the actuating shaft and then secured in the housing by the second housing part.

[0013] The housing components can be locked together, allowing the housing to be assembled without tools.

[0014] The locking mechanism can be achieved particularly easily by making one housing part of metal and the other of plastic. The plastic part can be flexible, particularly elastic, so that locking can be achieved more easily. The metal housing part can have screw holes so that the housing part, and thus the entire housing, can be fixed to the wing.

[0015] A first guide element can be arranged on the locking element, and a second guide element can be arranged on the transmission element; these elements interact when the parking brake is released. In particular, this allows for central fixation, allowing the fitting to be mounted in the correct position on the sash. Furthermore, the interaction of the two guide elements can provide an anti-rotation feature. This prevents the actuating shaft from accidentally twisting and the parking brake from being accidentally activated. For example, a groove can be provided on the transmission element, and a web can be provided on the locking element, which is guided in the groove.

[0016] According to a further embodiment of the invention, a drive rod can be provided, and the locking element can be coupled to the drive rod without stroke compensation. This allows a direct coupling of the locking element and drive rod. No additional elements are required to achieve stroke compensation.

[0017] The scope of the invention also includes a window, a door or the like with a fitting arrangement according to the invention.

[0018] Further features and advantages of the invention will become apparent from the following description of exemplary embodiments of the invention with reference to the figures of the drawing, which illustrate details essential to the invention, as well as from the claims. The features shown therein are not necessarily to scale and are presented in such a way that the special features of the invention can be clearly seen. The various features can be implemented individually or in combinations in variants of the invention.

[0019] The schematic drawing shows embodiments of the invention in various stages of use and is explained in more detail in the following description.

[0020] They show: Fig. 1 is a perspective view of a window with an open sash and a fitting arrangement according to the invention; Fig. 2 is a partially exploded view of a first embodiment of the fitting arrangement according to the invention; Fig. 3 is a side view of the fitting arrangement according to the first embodiment; Fig. 4 is a sectional view along the line IV-IV of the Figure 3 ; Fig. 5a-d various locking positions to explain the activation of the parking brake; Fig. 6 a sectional view through a window with closed sash; Fig. 7 one of the Figure 2 corresponding representation of a second embodiment of the fitting arrangement according to the invention; Fig. 8 one of the Figure 3 corresponding representation of a second embodiment of the fitting arrangement; Fig. 9 a sectional view along the line IX-IX in the Figure 8 ; Fig.10a-cRepresentations to explain the second embodiment of the fitting arrangement; Fig. 11a two-part housing.

[0021] The Figure 1 shows a partial perspective view of a window 10 with a fixed frame 12 and a sash 14. The sash 14 is open in the position shown. In the open position shown, the sash 14 is secured by a parking brake 16. The parking brake 16 has a slider 18 that is movable relative to a guide 20 when the parking brake 16 is released. The slider 18 can be secured in different positions relative to the guide 20 via an actuating shaft 22 of a fitting arrangement 24. The slider 18 is coupled to the fixed frame 12 via a link 26.

[0022] The fitting assembly 24 has a gear 28, by which a rotary movement of an actuating handle (not shown), for example a handle, can be converted into a linear movement of a drive rod 30. The drive rod 30 is coupled to a locking element (not shown here), which can interact in the region of a housing 32 with a transmission element 34, which is connected in a rotationally fixed manner to the actuating shaft 22.

[0023] The Figure 2shows the fitting arrangement 24 in a partially exploded view. Here, the locking element 36 can be seen, which can be coupled to the drive rod 30 via a coupling section 31 and can be driven by it in the direction of the double arrow 38. A locking pin 40 is coupled to the locking element 36, which, in a closed position, also serves to lock the sash 14 to the frame 12. It can be seen that the transmission element 34 is mounted in the housing 32. The actuating shaft 22 has a flattened section 40, which allows a rotationally fixed arrangement of the transmission element 34 on the actuating shaft 22, wherein the transmission element 34 has a receptacle whose cross-section is adapted to the cross-section of the actuating shaft 22.

[0024] The Figure 3 shows a side view of the fitting arrangement 24. The elements described so far are indicated with corresponding reference numbers.

[0025] The Figure 4shows a sectional view along line IV-IV of the Figure 3 .

[0026] In the Figure 4 It can be seen that a coupling section 42 is arranged on the locking element 36, which in the illustrated embodiment is designed as a tooth. On the transmission element 34, in contrast, a coupling section 44 is arranged, which is designed as a tooth gap. The locking element 36 is in its lower end position. The coupling sections 42, 44 are spaced apart from one another and not coupled to one another. Furthermore, it can be seen that the actuating shaft 22 is received in the receptacle 46 of the transmission element 34, and the transmission element 34 is arranged on the actuating shaft 22 in a rotationally fixed manner.

[0027] The perspective representation of the Figure 5a essentially corresponds to the Figure 4The locking element 36 is in its lower end position. The coupling sections 42, 44 are not coupled to each other. If the drive rod 30 is actuated and the locking element 36 is moved upwards, as shown in the Figure 5b As can be seen, the coupling section 42 engages with the coupling section 44. The transmission element 34 is not yet rotated. If the drive rod 30 and thus the locking element 36 are moved further upwards, the transmission element 34 is carried along by the locking element 36 due to the coupling of the coupling sections 42, 44, so that the transmission element 34 and thus the actuating shaft 22 are rotated, see Figure 5c .

[0028] In the Figure 5dA further end position of the locking element 36 is shown. This position corresponds to a braking position of the parking brake 16. The actuating shaft 22 is rotated to its maximum. The coupling section 42 is no longer completely located in the coupling section 44. These are at least partially decoupled. In contrast, the coupling section 42 represents a reverse rotation lock, since a stop 46 of the transmission element 34 is blocked by the coupling section 42. Furthermore, it can be seen that the locking element 36 projects with its free end 48 upwards beyond the housing 32, which can be arranged in the fitting part groove of the sash 14. The free end 48 of the locking element 36 can thus interact with a locking piece 50 arranged on the fixed frame 12, as shown in the Figure 6is shown. Accordingly, in an upper end position of the locking element 36, the free end 48 of the locking element 36 engages the locking piece 50 when the sash 14 is in a closed position. This provides additional locking of the sash 14 to the frame 12.

[0029] The parking brake is released in the reverse order of Figure 5a - 5d When the locking element 36 is retracted via the drive rod 30, the coupling section 42 moves into the coupling section 44 and then, upon further downward movement of the locking element 36, takes the transmission element 34 with it, so that the parking brake 16 is released. After the parking brake 16 is released, the locking element 36 is moved further downward, so that the coupling sections 42, 44 are decoupled. Due to the decoupling, it is possible to provide a greater stroke for the movement of the locking element 36 than in the prior art.

[0030] The Figure 7shows an alternative embodiment of a fitting assembly 124 according to the invention. The fitting assembly 124 also has the drive rod 30, which can be coupled to the coupling section 31 and is movable in the direction of the double arrow 38. A locking element 136 can be moved by the drive rod 30. The locking element 136 interacts with a transmission element 134 mounted in a housing 132. The actuating shaft 22 can be inserted into the transmission element 134, so that the transmission element 134 and the actuating shaft 22 are connected to one another in a rotationally fixed manner. A locking pin 40 can also be moved via the drive rod 30.

[0031] The Figure 8 shows a representation analogous to Figure 3 the fitting arrangement 124. Elements already described are entered with corresponding reference numbers.

[0032] The Figure 9 shows a sectional view along the line IX-IX of the Figure 8. Here, it can be seen that the locking element 136 also has a coupling section 42 designed as a tooth, which can interact with a coupling section 44 of the transmission element 134 designed as a tooth gap. The locking element 136 additionally has a guide element 150 designed as a projection, which is arranged centrally with respect to the width of the locking element 136. Furthermore, the guide element 150 is arranged at the top of the locking element 136. In the position shown, in which the coupling sections 42, 44 are not yet in engagement with one another, the guide element 150 projects into a corresponding guide element 152 of the transmission element 134, which guide element is designed as a groove. The guide element 152 is, in particular, slot-like or groove-like.The guide elements 150, 152 hold the transmission element 134 and thus the actuating shaft 22 in an assembly position, so that the transmission element 134 and the actuating shaft 22 are correctly oriented when the fitting assembly 124 is installed. When the fitting assembly 124 is installed, the interaction of the guide elements 150, 152 in the position shown ensures that the transmission element 134 cannot be accidentally rotated. The parking brake 16 is thus reliably held in an open position.

[0033] A corresponding position in a perspective view is shown in the Figure 10a shown. The coupling sections 42, 44 are not yet engaged with each other. The locking element 136 is in a lower end position. If the locking element 136 is moved, as shown in the Figure 10bis shown, is moved upwards, the guide elements 150, 152 are disengaged because the guide element 150 leaves the guide element 152 upwards. The transmission element 134 is thus released for a rotational movement, which is initiated by the interaction of the coupling sections 42, 44. If the locking element 136 is moved even further upwards, as shown in the Figure 10c As shown, the parking brake 16 is in a braking position. The coupling section 42 is outside the coupling section 44 and interacts with a stop 146, so that a reverse rotation lock is active. The free end 148 of the locking element 136 protrudes beyond the housing 132 far enough that the free end 148 can interact with a corresponding locking piece.

[0034] The Figure 11shows that the housing 132 is formed in two parts, namely with an upper housing part 133 and a lower housing part 131. The upper housing part 133 can be made of metal, while the lower housing part 131 can be made of plastic. The lower housing part 131 can be locked to the upper housing part 133. Before locking, the transmission element 134, which has an opening whose cross-section is adapted to the cross-section of the actuating shaft 22, can be inserted between the housing parts 131, 133. By locking the housing parts 131, 133, the transmission element 134 is reliably mounted in the housing 132.

[0035] The housing part 133 has screw openings 135 through which screws can be passed in order to fasten the housing 132 and thus the fitting arrangement 124 to the sash 14.
