Description

[0001] The invention relates to a damper fitting with the features of the preamble of claim 1. Furthermore, the invention relates to a door or window arrangement with the features of the dependent claim.

[0002] A damper fitting and a door or window assembly equipped with it are known, for example, from EP 3 034 752 A1. The damper fitting described therein has a sash-side damper and a follower coupled to the damper, which is movable along a guide track and pivots downwards in an end position. On the frame side, a holder with an attached projection is provided, which can engage with the follower depending on the sash's position. The follower or the projection is spring-mounted perpendicular to the guide track to facilitate coupling between the projection and the follower. With this damper fitting, the projection and follower must be precisely aligned for reliable operation due to the spring-mounted mounting. The spring-mounted mounting also limits the maximum forces that can be transmitted.

[0003] The invention is based on the objective of providing a simple, robust damper fitting that does not require readjustment, using simple design means.

[0004] The invention solves this problem by means of a damper fitting with the features of claim 1.

[0005] The damper fitting is designed and / or intended for a door or window assembly comprising a frame and a sliding sash. The damper fitting includes a damping device (on the sash side) and a release element (on the frame side).

[0006] The damping device comprises a housing to which a (linear) damper is attached at one end. The damper has at the other end a retractable piston rod, the free end of which is coupled to a receiving unit.

[0007] The housing of the damping device has a housing section in which a base and two wall sections projecting from the base and opposing each other define a guide channel.

[0008] The receiving unit is slidably guided in the guide channel and can be moved between a ready position, in which the receiving unit is located at the end of the guide channel furthest from the damper (extended position), and a retracted position, in which the receiving unit is located near or at the end of the guide channel closest to the damper (retracted position). The damper exerts only a damping effect (via the piston rod on the receiving unit).

[0009] The receiving unit has a mechanism with two opposing clamping jaws, each pivotably mounted on the receiving unit, which can be actuated at least indirectly (directly or directly) by the release piece.

[0010] The mechanics of the receiving unit are arranged such that the clamping jaws are in a swung-out position when the receiving unit is in its ready position, in which the clamping jaws extend beyond the clear cross-section of the guide channel with rear-engaging sections (laterally, i.e. towards the wall sections) and engage the wall sections (at the end of the guide channel facing away from the damper) from the front.

[0011] This allows the receiving unit to be held at the end of the guide channel furthest from the damper. This prevents the receiving unit from shifting or being pulled into the retracted position. The release element can then, at least with a release section, move into or out of a receiving space between the clamping jaws.

[0012] The mechanics of the receiving unit are also designed in such a way that the clamping jaws can be pivoted into a pivoted position when actuated by the release piece, whereby the rear grip between the rear grip sections and the wall sections is released and the clamping jaws lie within the clear cross-section of the guide channel, so that the receiving unit can be moved into the retracted position.

[0013] In this way, with a door or window assembly equipped with the damper fitting, the sliding sash can be softly pushed or pulled shut (pushing or pulling is done by the user's muscle power, with the damper damping this movement). When the clamping jaws are in the pivoted position, at least the release section of the release mechanism can be trapped in the receiving area.

[0014] The proposed design of the damper fitting contributes to a structurally simple and robust construction. The damper fitting is easy to adjust, as the release element only needs to be positioned relative to the damping mechanism so that the release element and the clamping jaws interact, or more precisely, so that the release element can penetrate the receiving space between the clamping jaws. This can be easily accomplished when installing the damper fitting on a door or window assembly, making an adjustment perpendicular to the direction of movement (along the direction of gravity) unnecessary.

[0015] The damping device is designed in such a way that the receiving unit, when moved between its ready position and its retracted position, does not change its height relative to the base of the housing (position relative to the base along the vertical direction oriented orthogonally to the base). This contributes to a comparatively small footprint for the damping device.

[0016] The release mechanism can have a mounting section for attachment to the frame and a release section projecting from it. The release mechanism can have an overall T-shaped shape. The release section can have a circular or elliptical cross-section. The mounting section can have a cuboid shape with a through-hole at each end for attaching the release mechanism to the frame, e.g., by screwing it in.

[0017] The linear damper can be designed as a pure piston damper (without a biasing force direction). The damper thus exerts only a damping effect and is therefore neither biased in the direction of retraction (towards the retracted position) nor against the direction of retraction (away from the retracted position). In other words, the damper merely counteracts a force applied, for example, to the receiving unit. Specifically, it can be a pure oil damper, a gas pressure damper, or a combination of both, a so-called damper with a separating piston. Closing (moving into the closed position) and / or opening (moving into at least a partially open position) a sash of the door or window assembly is done manually (by muscle power) by a user or operator.

[0018] As already indicated, in a preferred embodiment, the clamping jaws can be shaped and / or spaced apart from one another in such a way that they define or delimit a receiving space between them, at least for a release segment of the release element. Each clamping jaw has a distal end section (facing away from the receiving unit). When the clamping jaws are swung out (ready position of the receiving unit), the distal end sections define an opening between them to the receiving space, which is passable for the release segment. The release segment of the release element can then enter or exit the receiving space. When the clamping jaws are swung inward, the opening is reduced by the distal end sections to such an extent that the opening is not passable for the release segment of the release element. The release segment of the release element is then trapped in the receiving space.The release mechanism is then coupled to the receiving unit. This allows the sash of the door or window assembly to be pulled closed and pushed open.

[0019] The recording space can extend (orthogonal to the direction of movement of the recording unit) along the entire height of the clamping jaws, thus providing a large coupling area between the release section and the clamping jaws.

[0020] Optionally, a lead-in chamfer can be formed on the distal end sections of each clamping jaw. This lead-in chamfer facilitates the insertion of the release element into the receiving space between the clamping jaws, for example, when the release element and the insertion device are not precisely aligned. When the clamping jaws are in the swung-out position, the lead-in chamfers can form an angle with each other, which can be, for example, 20° to 70°.

[0021] Advantageously, the distal end sections can rest against each other when the clamping jaws are swivelled into position. This largely closes off the receiving space. Because the distal end sections rest against each other, they are stabilized relative to one another.

[0022] In a preferred embodiment, the distal end sections of the clamping jaws can each have incisions, separated from each other by an uncut section. On the clamping jaws, the incisions and uncut sections are positioned opposite each other such that, when the clamping jaws are pivoted, the uncut sections of one clamping jaw rest against or within the incisions of the other clamping jaw. In other words, when the clamping jaws are pivoted, the uncut sections of one clamping jaw engage with the incisions of the other clamping jaw. This increases the stability of the clamping jaws relative to each other in the pivoted position. Furthermore, this reduces the space required by the clamping jaws in the pivoted position, allowing the cross-section or width of the housing's guide channel to be kept comparatively small.

[0023] Specifically, the clamping jaws can each be pivotally mounted on the receiving unit or a receiving body of the receiving unit by means of a cylindrical pin. This creates a structurally simple and stable mounting of the clamping jaws. The cylindrical pins can be oriented parallel to each other (central longitudinal axes of the cylindrical pins parallel to each other). The central longitudinal axes of the cylindrical pins can be aligned orthogonally to the direction of movement of the receiving unit or to the central longitudinal direction of the guide channel.

[0024] Advantageously, the mechanism of the receiving unit can include a locking element which is slidably guided in a recess of the receiving unit (along the direction of movement) and pre-tensioned by a spring towards the clamping jaws. In the ready position of the receiving unit, the locking element engages with the clamping jaws such that the clamping jaws are locked in the pivoted position. Thus, the clamping jaws are securely locked in the pivoted position, and the force exerted on the receiving unit by the damper in the direction of retraction is reliably counteracted. Pivoting the clamping jaws into the pivoted position is blocked in the ready position of the receiving unit. The spring is, in particular, a compression spring, which can, for example, be designed as a helical spring.

[0025] Specifically, the locking element can have two locking openings, and the clamping jaws can each have a proximal end section (facing the receiving unit). In the ready position of the receiving unit, the proximal end sections engage at least partially in the locking openings. This is a structurally simple and robust design for securely locking the clamping jaws.

[0026] In a preferred embodiment, the locking element can have an actuating section that extends between the clamping jaws and, at least in the ready position of the receiving unit, projects into the receiving space between the clamping jaws. This allows the locking element to be repositioned within the receiving unit by actuating the actuating section via the release section of the release element, thereby releasing the clamping jaws from the locking element. This contributes to a comparatively high reliability of the damper fitting during operation, as the clamping jaws only begin to release in the pivoted position when the release section is located in the receiving space between the clamping jaws and actuates the actuating section.

[0027] Advantageously, the locking element can have two collars, each of which outwardly defines one of the locking openings (each collar defines one locking opening). The collars each have an edge, preferably rounded, at their free end. The proximal end sections each have an outer flank, the outer flanks and the preferably rounded edges sliding against each other when the actuating section is actuated by means of the release section. This ensures that the release of the locking mechanism in the pivoted position and the transition from the pivoted position to the pivoted position do not occur abruptly, but rather gradually as a result of the sliding of the edges and the outer flanks. This contributes to a smooth movement of the sash of a door or window assembly.

[0028] The outer flanks of the proximal end sections can each have a straight section and a subsequent, in particular arc-shaped, curved section. The curved section is preferably located at the free end of the proximal end section. The straight section contributes to a large contact area with the collar of the locking element. The curved section contributes to a gradual transition from the pivoted-out position to the pivoted-in position.

[0029] Specifically, the collars of the locking element can each have a rounded outer flank. The proximal end sections of the clamping jaws each have an inner flank. The outer flanks of the locking element and the inner flanks of the proximal end sections of the clamping jaws slide against each other when the clamping jaws are moved from the pivoted position to the pivoted position by the release section of the release pin. This contributes to a smooth transition of the clamping jaws from the pivoted position to the pivoted position and prevents the components from jamming together. This prevents an abrupt disengagement of the damping device and release element, or more precisely, of the clamping jaws and release section, when the sash of a door or window assembly is slid open.

[0030] The contours described above (rounded edge, outer flank, outer flank, inner flank) do not have to be formed along the entire component carrying the respective contour, but can also be formed only over one or more sections of the respective components.

[0031] Advantageously, the rear gripping sections of the clamping jaws can each have a sliding surface, preferably convex, on their side facing the wall sections. This sliding surface is raised relative to a subsection adjoining the sliding surface inwards (towards the pivot axis of the clamping jaws). This provides precisely targeted sliding surfaces that facilitate a transition from the pivoted-out position to the pivoted-in position, as the sliding surfaces can slide from the end face of the wall sections to the inner surface of the wall sections and along the inner surface of the wall sections.

[0032] The housing of the damping device can be made of sheet steel, for example, as a laser-bent or stamped part. Regardless of the material, the housing can have a mounting tab with a through-hole at each end for attaching it to a sash of a door or window assembly, for example, by screwing it in place. Optionally, clamping tabs can be provided in a central section of the housing for (additional) securing of the damper. The damper can be screwed to the housing at its fixed end (the end furthest from the piston rod).

[0033] The receiving unit (its housing, so to speak) can have a receiving body to which the components of the receiving unit are attached and / or (possibly pivotably) mounted. The receiving body can be made of die-cast zinc, cast steel, or injection-molded plastic.

[0034] The locking element can be made of zinc die-casting or plastic injection molding. The clamping jaws can be made of stainless steel investment casting or plastic injection molding. The release element can be made of stainless steel investment casting.

[0035] The locking element can have a spring engagement section for holding or positioning the spring. This ensures reliable coupling between the spring and the locking element. The spring engagement section can have a cylindrical cross-section, allowing it to penetrate the eye of the spring.

[0036] The locking element can have two further collars extending parallel to the spring engagement section. These further collars can have an outer surface that forms part of an outer contour of the locking element or extends an outer contour of the locking element, with the locking element being guided by this outer contour in the recess for the locking element formed in the receiving unit. The further collars are preferably oriented away from the collars of the locking element already described above.

[0037] The receiving body can have a spring retaining section that holds the spring at the end furthest from the locking element within the receiving unit or its receiving body. The spring retaining section has a spring section receiving chamber, preferably cylindrical, which is bounded by a wall, preferably circumferential. Independently of this, the receiving unit or its receiving body can have a bore at the end facing the piston rod of the damper, in which the piston rod is fastened. The piston rod can be fastened by a threaded connection (e.g., internal thread in the bore and external thread at the free end of the piston rod) or by a positive-locking connection (e.g., pin receptacle on the piston rod and insertable pin).

[0038] The aforementioned problem is also solved by a door or window arrangement with the features of the dependent claim. Regarding the advantages achievable thereby, reference is made to the relevant explanations concerning the damper fitting.

[0039] The door or window assembly comprises a (fixed) frame, a sash that is movable relative to the frame between an open and a closed position along a sliding direction, and a damper fitting with one or more of the aspects described above. The damper is arranged and, if necessary, attached to the sash, and the release mechanism is arranged and, if necessary, attached to the frame, with the damper and release mechanism facing each other.

[0040] "Facing each other" means that, depending on the position of the wing relative to the frame along the direction of movement, the release piece can be coupled to the damping device.

[0041] The release mechanism and the damping device are each arranged on an end face of the frame and the sash, respectively, which move relative to each other when the sash is moved along the direction of movement. Preferably, the release mechanism can be arranged on a lower (sash-facing) side of an upper frame cross member, and the damping device can be arranged on an upper (frame-facing) side of an upper sash cross member.

[0042] The sash can be a sliding sash or a lift / slide sash.

[0043] Preferably, the release element is attached to the frame along the direction of movement such that when the damping device, during the closing of the sash, encounters the release element or the release section of the release element with its clamping jaws, the sash is still open by a defined dimension s. In other words, in this position, the sash would still need to be moved by the defined dimension s to reach the closed position relative to the frame. The release element must then be positioned on the frame such that the travel w of the receiving unit between the ready position and the retracted position is greater than or equal to the defined dimension s (w ≥ s).

[0044] The measures discussed in connection with the damper fitting and / or those explained below can be used to further design the door or window arrangement.

[0045] The invention is explained in more detail below with reference to the figures, where identical or functionally identical elements are provided with identical reference numerals, possibly only once. The figures show: Fig. 1 a door or window arrangement with a damper fitting in a schematic front view; Fig. 2a-c the damper fitting made of Figure 1 in a side view ( Figure 2a ), a perspective top view ( Figure 2b ) and a sectioned and perspective partial view ( Figure 2c ); Fig.3a,bden damper fitting made of Figure 1 in a sectional and partial top view ( Figure 3a ) as well as in a cut and partial side view according to the section axis IIIb-IIIb in Figure 3a (Figure 3b ); Fig. 4a-8 shows the sequence of movements when the sash of the door or window assembly is pushed shut, based on several sectional and partial top views of the damper fitting. Figure 1; and Fig. 9a-11b the sequence of movements when sliding the wing open, based on several sectioned and partial top views of the damper fitting. Figure 1 .

[0046] Figure 1 shows a schematic front view of a door or window arrangement, which is collectively designated with the reference numeral 100.

[0047] The door or window assembly 100 has a (fixed) frame 102, which includes an optional lower frame cross member 104, an upper frame cross member 106, and two vertical frame members 108, 110. The lower frame cross member 104 is optional and can be omitted if the door or window assembly 100 is designed to be barrier-free (level threshold).

[0048] The door or window assembly 100 in the example also has a fixed panel 112, which is attached to the frame 102 and is immovable relative to the frame 102. The fixed panel 112 can have a glazed segment 114. Instead of the fixed panel 112, a movable sash can be provided (double-leaf elements; not shown). The damper fitting described below can be used with single-leaf or double-leaf elements.

[0049] The door or window assembly 100 also has a sash 116 that is movable relative to the frame 102 between an open position and a closed position along a sliding direction vr. The sash 116 has a lower sash cross member 118, an upper sash cross member 120, and two vertical sash mullions 122, 124. The sash 116 may have a glazed segment 117.

[0050] Furthermore, the door or window arrangement 100 has a damper fitting 10, wherein the damper fitting 10 has a sash-side damping device 12 and a frame-side release piece 14.

[0051] The damping device 12 is arranged on the sash 116 and the release piece 14 is arranged on the frame 102, with the damping device 12 and the release piece 14 facing each other. Depending on the position of the sash 116 relative to the frame 102, the release piece 14 can be coupled along the displacement direction vr of the damping device 12. In the example, the release piece 14 is arranged and attached to a lower side (facing the sash 116) of the upper frame cross member 106 of the frame 102. The damping device 12 is arranged and attached to an upper side (facing the frame 102) of the upper sash cross member 120 of the sash 116. Figure 1 (indicated at the points opened for illustration).

[0052] The sash 116 can be configured as a sliding sash or as a lift-and-slide sash. Using the handle 126, the sash 116 can be moved by an operator and locked or unlocked on the frame 102 by pivoting the handle 126 accordingly.

[0053] The construction of the damper fitting 10 is described in particular with reference to the Figures 2a to 3b described in more detail below.

[0054] The release element 14 has a mounting section 16, which is essentially cuboid in shape and has a passage 18 at both ends for attaching the release element 14 to the frame 102. A release section 20 extends from the mounting section 16 and, in this example, has a circular cross-section. The release element 14 is essentially T-shaped.

[0055] The damping device 12 has a housing 22, which has a mounting tab 23 at each end for attaching the retraction device 12 to the wing 116, e.g., by screwing it in place. A linear damper 24 is attached to one end of the housing 22 (retaining bolt 25). At the other end, the damper 24 has a retractable piston rod 26, which is neither preloaded in the retraction direction nor against the retraction direction (purely damping effect without a preloading force direction).

[0056] In this example, the housing 22 has optional clamping tabs 28 by means of which the damper 24 can be additionally fixed to the housing 22 at its end facing the piston rod 26. The housing 22 has a housing section 30 in which a base 31 and two opposing wall sections 32 projecting from the base 31 define a guide channel 33.

[0057] The piston rod 26 is coupled at its free end to a receiving unit 36. The receiving unit 36 ​​is slidably guided in the guide channel 33 and is positioned between a ready position, in which the receiving unit 36 ​​is located at the end of the guide channel 33 facing away from the damper 24 (see, for example, the figure shown in ... Fig.2b and 2c ) and can be moved into a retracted position in which the receiving unit 36 ​​is located near the end of the guide channel 33 facing the damper 24.

[0058] The receiving unit 36 ​​comprises a receiving body 37 and a mechanism 38. The mechanism 38 has two opposing clamping jaws 40, each pivotably mounted on the receiving unit 36, a locking element 42, and a spring 44 (see, for example, Figure 3). Fig.2c or 3a ).

[0059] In the example, the clamping jaws 40 are each pivotably mounted on the receiving unit 36 ​​or its receiving body 37 by means of a cylindrical pin 45 (see e.g. Fig. 2c or 3a The clamping jaws 40 define between themselves a receiving space 46 for the release section 20 of the release piece 14. The clamping jaws 40 are in a swung-out position (see figure). Fig.3a ) and pivotable into a swiveled position (see below). Fig. 7c or 8a).

[0060] The clamping jaws 40 each have a distal end section 47 and a proximal end section 48 (see figure). Fig.3a The distal end section 47 faces away from the receiving unit 36 ​​or its receiving body 37. The proximal end section 48 faces the receiving unit 36 ​​or its receiving body 37.

[0061] A leading-edge chamfer 49 is formed on each of the distal end sections 47 of the clamping jaws 40.

[0062] Incisions 50 are formed at the distal end sections 47 of the clamping jaws 40, each of which is separated from the other by an uncut section 51 (cf. Fig.2c and 3b ). On the clamping jaws 40, incisions 50 and uncut sections 51 are positioned opposite each other in such a way that, when the clamping jaws 40 are pivoted into the indentation position, the uncut sections 51 of one of the clamping jaws 40 abut against or within the incisions 50 of the other clamping jaw 40 (see, for example, Fig. 7c ).

[0063] The locking element 42 is slidably guided in a recess 53 of the receiving unit 36 ​​or its receiving body 37 along the direction of displacement vr and is pre-tensioned in the direction of the clamping jaws 40 by means of the spring 44. The locking element 42 has an outer contour 54 extending in a straight line in this example, by means of which the locking element 42 is guided on a wall 55 of the recess 53 (see figure). Fig.3a). The locking element 42 is engaged with the clamping jaws 40 in the ready position of the receiving unit 36 ​​such that the clamping jaws 40 are locked in the swung-out position (cf. e.g. Fig.3a or Fig.4a ).

[0064] The locking element 42 has two locking openings 56. In the ready position of the receiving unit 36, the proximal end sections 48 of the clamping jaws 40 engage at least partially in the locking openings 56 (see figure). Fig.3a or Fig.4a ).

[0065] The locking element 42 has an actuating section 57 that extends between the clamping jaws 40 and, at least in the ready position of the receiving unit 36, projects into the receiving space 46 between the clamping jaws 40. The locking element 42 can thus be moved within the receiving unit 36 ​​by actuating the actuating section 57 using the release section 20 of the release piece 14, thereby releasing the clamping jaws 40 from the locking element 42 (see Figure 1). Fig.4b to Fig.5b ).

[0066] The locking element 42 has two collars 58, each of which limits one of the locking openings 56 to the outside (cf. Fig.3a and Fig.4a The collars 58 in the example each have a rounded edge 59 at their free end. In addition, the collars 58 each have a rounded outer flank 60, which in each case transitions into the straight outer contour 54 in the example.

[0067] The locking element 42 has a spring engagement section 61 for holding or positioning the spring 44, wherein the spring engagement section 61 in the example has a circular cross-section in order to penetrate into the eye of the spring 44 (see figure). Fig.4a The locking element 42 has two further collars 62 that extend parallel to the spring engagement section 61. The further collars 62 have an outer surface that forms part of the outer contour 54 of the locking element 42.

[0068] The receiving body 37 has a spring retaining section 63, with which the spring 44 is held at the end facing away from the locking element 42 in the receiving unit 36 ​​or its receiving body 37. The spring retaining section 63 has a spring section receiving chamber 64, which in this example is cylindrical and is bounded by a wall 65, preferably circumferential (see figure). Fig.4a ).

[0069] In the example, the receiving unit 36 ​​or its receiving body 37 has a bore 66 with an internal thread 67 at the end facing the piston rod 26 of the damper 24 (see figure). Fig.4a ), in which the piston rod 26 is fastened to the free end of the piston rod 26 by a corresponding external thread 68 (cf. Fig.2c Other coupling options are also conceivable, as described above.

[0070] The proximal end sections 48 each have an outer flank 69 and an inner flank 70, which meet at a point at the free end (cf. Fig.6a The outer flanks 69 in the example each have a straight section 71 and an arcuate section 72. The curved section 72 is located at the free end of the proximal end section 48.

[0071] The inner flank 70 of the proximal end sections 48 has an arc-shaped curved section 73 at the free end, which (away from the free end) transitions into a straight section 74 (cf. Fig.6a The curved section 73 of the inner flank 70 is larger than the curved section 72 of the outer flank 70. In the example, the curved section 73 of the inner flank 70 extends the same distance from the free end as the straight section 71 and the curved section 72 of the outer flank 70 combined.

[0072] The clamping jaws 40 have rear gripping sections 75 at the distal end sections 47, with which the clamping jaws 40, in their swung-out position, can grip the wall sections 32 from behind (cf. Fig.4bThe backhand sections 75 each have a convex sliding surface 76 on their side facing the wall sections 32. The sliding surfaces 76 are each raised to form a subsection 77 adjoining the sliding surface 76 to the inside.

[0073] The following refers to the Figures 4a to 8 The sequence of movements when closing the wing 116 is described.

[0074] Figure 4a Figure 1 shows the ready position of the receiving unit 36, in which the receiving unit 36 ​​is located at the end of the guide channel 33 facing away from the damper 24. The clamping jaws 40 are in a pivoted position, in which the clamping jaws 40 project beyond the clear cross-section of the guide channel 33 with rear-engaging sections 75 and engage the wall sections 32 from behind.

[0075] When the clamping jaws 40 are swung outwards, the distal end sections 47 define an opening 78 between them leading to the receiving chamber 46, which is passable for the release section 20 of the release piece 14. The release section 20 of the release piece 14 is located in Figure 4a outside the recording space 46. The wing 116 or the damping device 12 have not yet reached the position of the release piece 14 or the release section 20 when being pushed closed relative to the frame 102.

[0076] In Figure 4b The wing 116 was moved a little further along the direction of travel towards the closed position. The release section 20 has passed the opening 78 and is now located in the receiving chamber 46 between the clamping jaws 40, with the release section 20 just coming into contact with the actuating section 57.

[0077] In Figure 4cThe wing 116 was pushed a little further, whereby the clamping jaws 40 were indirectly actuated by the release section 20. This occurs when the release section 20 actuates the actuating section 57 of the locking element 42, thereby displacing the locking element 42 against the force of the spring 44 in the receiving unit 36 ​​in order to release the clamping jaws 40 from the locking element 42.

[0078] The outer flanks 69 of the proximal end sections 48 and the rounded edges 59 of the collars 58 of the locking element 42 slide against each other when the actuating section 57 is actuated by means of the release section 20. Figure 4c the moment when the rounded edges 59 are each located at the transition from the straight section 71 to the curved section 72. Up to this moment, the clamping jaws 40 were only pivoted minimally about the cylindrical pin 45 forming their pivot axis.

[0079] In Figure 5a The sash 116 was pushed a little further, whereby the locking element 42 was displaced further against the force of the spring 44. The rounded edges 59 of the collars 58 of the locking element 42 now slide on the curved sections 72 of the outer flanks 69. As a result of the tensile force acting on the receiving unit 36 ​​by an operator (the operator moves the sash 116 towards the closed position), which seeks to move the receiving unit 36 ​​into the retracted position, and the pivoting movement of the clamping jaws 40 already partially released by the locking element 42, the clamping jaws 40 have already been pivoted by a certain angle.

[0080] In Figure 5bThe wing 116 was pushed a little further, whereby the locking element 42 was displaced by means of the release section 20 so far against the force of the spring 44 that the locking of the clamping jaws 40 relative to the locking element 42 is released. The proximal end sections 48 are located completely outside the locking openings 56 of the locking element 42. The release section 20 is now in contact with the concavely rounded inner contour 79 of the clamping jaws 40, which delimits the receiving space 46.

[0081] In Figure 5c It can be seen that the wing 116 was pushed a little further and the locking element 42 was moved further against the force of the spring 44 by means of the release section 20. The clamping jaws 40 were pivoted a little further.

[0082] The Figures 6a to 6cThe figures show the further sequence of movements. It can be seen that the wing 116 was pushed further inwards, with the release section 20 displacing the locking element 42 further against the force of the spring 44. The rear gripping sections 75 slide inwards with their convex sliding surfaces 76 along the end faces of the wall sections 32, and the clamping jaws 40 pivot further.

[0083] In Figure 7a The moment is shown when the convex sliding surfaces 76 are located at the edge 81 between the end face and the inner side of the wall sections 32. Figure 7b The sliding surfaces 76 have passed the edge 81.

[0084] Figure 7cFigure 1 shows the pivoted position of the clamping jaws 40. The rear grip between the rear grip sections 75 and the wall sections 32 is now released, and the clamping jaws 40 lie within the clear cross-section of the guide channel 33, so that the receiving unit 36 ​​can be moved into the retracted position by means of the damper 24. The release section 20 is trapped in the receiving space 46 in the pivoted position. When the clamping jaws 40 are pivoted, the opening 78 is reduced in size so that the release section 20 cannot pass through it. In this example, the clamping jaws 40 abut each other at their distal end sections 47, with the uncut sections 51 alternately engaging in the cuts 50, as explained above.

[0085] As in Figure 7cAs can be seen, the receiving body 37 of the receiving unit 36 ​​has a U-shaped opening 83 which allows the release section 20 to be moved within the receiving body 37 until the release section 20 rests against the closed end of the U-shaped opening 83 (in Fig.7c the case).

[0086] In Figure 8 The figure shows that the receiving unit 36 ​​is moved in the guide channel 33 towards the retracted position (retracted position not shown). The closing movement of the sash 116, which, for example, was pushed or "bumped" towards the closed position by an operator, is thereby dampened. This prevents the sash 116 from closing too quickly and thus from impacting the frame hard.

[0087] In the Figures 4a to 8The release section 20 (on the right in each figure) rests against the actuating section 57 or against the inner contour 79 of the clamping jaws 40. With respect to the sash 116, this means that the force applied to the sash 116 (closing movement), for example by an operator, is sufficient to move the sash 116 into the closed position. Through the interaction of the retraction device 12 and the release piece 14, the closing movement of the sash 116 is dampened (the frame-fixed release section 20 rests against the actuating section 57 or against the closed end of the U-shaped opening 83, and the movement of the sash-fixed housing 22 of the retraction device 12 relative to the receiving unit 36 ​​is dampened).

[0088] The following refers to the Figures 9a to 11bThe sequence of movements when sliding the sash 116 is described. To slide the sash 116, for example, an operator moves it from the closed position towards the open position (in the figures, the sash-fixed housing 22 of the retraction device 12 is moved to the right relative to the frame-fixed release section 20).

[0089] In Figure 9a The wing 116 has already been pushed open so far that the receiving unit 36 ​​is close to the ready position. The clamping jaws 40 are in the pivoted position and the release section 20 is trapped in the receiving chamber 46. The release section 20 rests against the inner contour 79 of the clamping jaws 40, specifically at the distal end sections 47. In other words, by pushing open the wing 116 and the frame-fixed release section 20, the receiving unit 36 ​​is pulled towards the ready position.

[0090] In Figure 9bThe wing 116 was pushed open a little further, with the convex sliding surfaces 76 located at the edge 81 between the front face and the inside of the wall sections 32, and the release section 20 beginning to pivot the clamping jaws 40 by bearing against the distal end sections 47. The incisions 50 and the unincised sections 51 (cf. Fig.2c and 3b The actuating section 57 may still be in contact with the release section 20. The proximal end sections 48 are not yet in contact with the locking element 42. The pivoting movement of the clamping jaws 40 is not abrupt, but dampened due to the coupling of the receiving unit 36 ​​with the damper 24.

[0091] In Figure 9cThe wing 116 was pushed open a little further, whereby the clamping jaws 40 were pivoted further by means of the release section 20, and the convex sliding surfaces 76 are now located on the front face of the wall sections 32. The actuating section 57 is no longer in contact with the release section 20. The proximal end sections 48 are in contact with the rounded outer flank 60 of the locking element 42 via their inner flank 70, more precisely via the curved section 73, whereby these elements slide against each other when the clamping jaws 40 are pivoted open. This dampens the pivoting movement of the clamping jaws 40, thus preventing a sudden opening.

[0092] In Figure 10a and 10b It is shown that as a result of the further sliding of the wing 116, the clamping jaws 40 are pivoted further. In Figure 10aThe inner flanks 70, more precisely the curved section 73, have slid a little further on the rounded outer flanks 60 of the locking element 42. Figure 10b Figure 1 shows how the tip is in contact with the rounded edge 59 of the locking element 42 between the outer flank 69 and the inner flank 70.

[0093] In Figure 10c As a result of the continued pivoting movement of the clamping jaws 40, the outer flank 69, more precisely the arcuate section 72, is in contact with the rounded edge 59 of the locking element 42. The release section 20 cannot yet pass through the opening 78 between the clamping jaws 40. The proximal end sections 48 have already penetrated a certain distance into the locking openings 56.

[0094] In Figure 11aThe rounded edge 59 of the locking element 42 is in contact with the straight section 71 of the outer flank 69. The proximal end sections 48 have already penetrated a little further into the locking openings 56.

[0095] In Figure 11b The pivoting process of the clamping jaws 40 (pivoting out) is complete. The clamping jaws 40 are in their pivoted position. The proximal end sections 48 have each fully penetrated the locking openings 56. The release section 20 can now pass through the opening 78 between the clamping jaws 40. The receiving unit 36 ​​is now in the ready position.
