Description

The invention relates to a fitting for a window, a door or the like, comprising drive rod means to be arranged in the rebate area of a casement, which can be moved by manual actuation in the longitudinal direction of the respective casement leg in order to adjust the fitting to the functional positions LOCKING LATCH, ROTATE, SPLIT TILT and, if necessary, TILT READINESS can, wherein on one and the same frame part fitting first engagement means assigned to the gap tilt position for a sash side, connecting rod-controlled engagement element and second engagement means associated with the locking state are provided. Such a fitting is known from EP-B1 51 309. Reference is made in particular to FIGS. 10, 11 and 12.

In the known fitting, one and the same sash-side engagement rod-controlled engagement element engages both in the engagement means assigned to the gap tilting position and in the engagement means assigned to the locking state.

From DE-A1 30 22 163 it is also known to use a sash-side, drive rod-controlled engagement element for gap tilting position and a further sash-side, drive rod-controlled engagement element for locking lock and to allow each of these engagement elements to interact with a separate frame part on the fitting, with separate fitting parts on each of these the engagement means are provided for the two engagement elements.

• a) einerseits die zweiten Eingriffsmittel an dem Beschlagteil in einer Richtung entsprechend einer Normalrichtung zur Blendrahmenebene verstellbar angeordnet sind und
• b) andererseits für die Schließverriegelung ein weiteres flügelrahmenseitiges treibstangengesteuertes Eingriffselement vorgesehen ist.

Furthermore, it is known from DE-A 27 53 262 to design fitting parts on the frame side so that alternatively different ones Wing frame-side, connecting rod-controlled engagement elements can interact with the frame part fitting part, wherein a first engagement means of the frame part fitting part is intended and suitable for cooperation with an engagement element which projects in the form of a locking block from a first connecting rod element perpendicular to its direction of movement, and a second engagement element of the frame part fitting part is designed to receive an engagement element which engages in the axial direction of a further drive rod element which extends orthogonally to the first-mentioned drive rod element and engages the latter. The latter engagement means is already designed so that the contact pressure can be changed when interacting with the associated engagement element. For this purpose, the latter engagement means can be adjusted with respect to the fitting part on the frame side, and in particular can be rotated. In contrast, it is proposed according to the invention in the case of a generic fitting according to EP-B1 51 309 that

• a) on the one hand the second engagement means are arranged on the fitting part in a direction corresponding to a normal direction to the frame level and
• b) on the other hand, a further drive rod-controlled engagement element is provided for the locking mechanism on the casement side.

According to the invention, one gains the advantage that even if one uses different sash-frame-side, connecting rod-movable engagement elements for the gap tilting position and for the locking mechanism, one fitting frame part on the frame side can be used to adjust the pressing action for the locking mechanism function position, this adjustment is simple can make a fitting part suitable for receiving an adjusting device and this without the fitting part as a whole vertically to have to adjust to the frame level. This means that the gap tilt position of the casement changes depending on its locking position. However, it was recognized that an exact mutual coordination of the locking locking position and the gap tilting position of the casement can be dispensed with, because the change in position of the engagement means for the locking locking state in the direction perpendicular to the frame level is relatively small, so that even with a small gap opening width, the position change Intervention means for the relative positional changes of the casement resulting in the locking position remain harmless in the locking position on the one hand and in the gap tilt position on the other hand.

The fitting according to the invention can be used in particular when the engagement element for engagement with the first engagement means assigned to the gap-tilt position is movable with a first drive rod element and the engagement element for the locking mechanism is movable with a second drive rod element which is essentially orthogonal to the first. In the following, the engagement element assigned to the gap tilt position is referred to as the first-mentioned engagement element and the engagement element assigned to the locking lock is referred to as the second-mentioned engagement element. The first-mentioned engagement element can be formed, for example, by an engagement block, which projects in a substantially orthogonal direction from the direction of movement of the first drive rod element, while the second-mentioned engagement element can be arranged in an extension of the second drive rod element.

The first-mentioned and the second-mentioned engagement element can, for example, be arranged on drive rod sections of a corner deflection. The first and that are preferred second drive rod element, regardless of whether they belong to a corner drive or not, attached to a pivot axis distant upper corner of the casement. In this case, the fitting part on the frame side can be arranged in particular on an upper frame member.

In order to be able to ensure a perfect interaction of the sash-side fitting parts on the sash and frame part, in particular as a result of the sash frame being set, it is proposed that the fitting part on the frame side move freely in the direction of movement of a first connecting rod element and be adjustable by adjustment surfaces is, which are arranged on the one hand on the fitting part and on the other hand in a fixed assignment to the range of movement of the first-mentioned engagement element, such that they come into engagement when the sash frame approaches a closed position relative to the frame and bring the fitting part into a desired position. This idea is already known from EP 51 309 B1, namely from FIGS. 10 and 12 there. The realization of this principle is of great importance in particular if more than three functional positions, that is to say in particular locking lock, turning, splitting and tilting readiness of the drive rod system are provided and accordingly there are only relatively small position distances between the positions of the drive rod system corresponding to the individual functions. However, the application of this principle in the present invention is unusual because when engagement means are attached to the frame part on the frame part, which are assigned to two different engagement elements, particularly when these two engagement elements are carried by mutually orthogonally movable connecting rod elements, this is not readily expected can be that a target position brought about with respect to the one engagement element without difficulty also for the other Intervention element is valid. The adjustment surface fixedly assigned to the range of motion of the first-mentioned engagement element can be attached to a faceplate section, in particular a faceplate section, which is combined with an associated drive rod element to form a structural unit and defines the range of motion of the first engagement element through an elongated hole.

The adjustment surfaces can be formed by a pairing of an adjustment funnel and an adjustment bar, as is also known per se from EP-B1 51 309. Here, as there, the adjustment funnel can be attached to the fitting part on the frame and the adjustment bar can be fixedly assigned to the range of movement of the first-mentioned engagement element, for example by attachment to the associated cuff rail.

The second engagement means can be formed by a rotating body which is rotatably and fixably mounted in the fitting part on the frame side about an axis parallel to the direction of movement of the second drive rod element, wherein this rotating body can be designed with an inner circumferential engagement surface lying eccentrically to its axis of rotation. The inner circumferential engagement surface can in particular have a polygonal outline.

In order to ensure - in particular when adjusting the fitting part on the frame side in adaptation to the first-mentioned engagement element intended for the gap-tilting position and specifically an adjustment in the direction of movement of the first drive rod element, for example by the funnel effect mentioned above - for a suitable assignment of the second-mentioned engagement element and the inner circumferential engagement surface of the rotating body , it is provided that the cross-sectional extent of the inner circumferential engagement surface in the direction of movement of the regardless of the rotational position, the first drive rod element is substantially larger than the extent of the second engagement element in this direction.

The rotating body can be ascertainable, for example, by friction in the fitting part on the frame side.

In order to be able to easily adjust the rotating body, it is advisable to design the inner circumferential engagement surface in such a way that it can be rotated with a turning mandrel, for example in the form of a conventional Allen key.

In order to be able to make the fitting part on the frame side right / left usable, it is provided that it is symmetrically doubled with respect to its longitudinal center in the direction of movement of the first drive rod element. The axis of the rotating body can lie in the longitudinal center of the fitting part on the frame side.

The hardware concept according to the invention is particularly applicable to double-sash windows which have a primary sash frame which can be rotated about a vertical primary axis of rotation and a secondary sash frame which can be rotated about a vertical secondary axis of rotation, the primary sash frame being assigned a primary fitting part group and the secondary sash frame being assigned a secondary fitting part group and the primary fitting part group and the secondary fitting part group each having a second-mentioned engagement element for movement along a vertical primary wing frame leg remote from the primary axis of rotation or for movement along a secondary wing frame leg remote from the secondary axis of rotation. The fittings for such double-sash windows with such second-mentioned engagement elements are known per se, particularly where the two sash frames are to be connected to one another without a vertical intermediate strip fixed to the frame and therefore for this purpose Care must be taken to ensure that the secondary casement can be fixed to the window frame when the primary casement is open, regardless of the locking of the primary casement. The term primary sash is used in the sense that the primary sash should always be the sash that is first opened for rotation, while the secondary sash should be the one that can only be opened after the primary sash has been opened and is therefore opened less frequently and may also be closed and should remain locked when the primary casement is opened. In order to at least give the primary casement the possibility of a tilt-and-tilt position in such double-wing windows, it is proposed that at least the primary fitting part group, in addition to the states of the locking mechanism and the readiness to rotate, permit a state of tilt-tilt and, if appropriate, a state of readiness to tilt by corresponding movement of the associated drive rod system. In addition, in order to make the fitting as small as possible and easy to process, it is further proposed that the drive rod systems of the two fitting part groups be assigned a common, frame-side fitting part which, in addition to the first engagement means for a first-mentioned engagement element assigned to the gap-tilt position, at least the primary sash frame second Has engagement means for second-mentioned engagement elements of both fitting part groups. This can be achieved in particular in that the second engagement means of the common fitting part for the respective second-mentioned engagement elements of the two fitting part groups are arranged symmetrically doubled with respect to the longitudinal center of the common fitting part.

In Fig. 1, a corner deflection of an ON casement is designated by 10. The associated casement and the associated frame are not shown. It is sufficient to point out here that the sash frame can be rotated about an axis of rotation D relative to the frame and can be tilted about a tilt axis K. To form the turning axis D, an extension arm 12 is used, which is pivotally mounted in a pivot bearing S on the frame around the axis of rotation D and is rotatably and displaceably guided on the sash frame by a rotary sliding guide 14 and in parallel position by locking means (not shown) on the upper sash frame leg this can be determined. For the rotary operation, the extension arm 12 is fixed on the upper wing frame leg in a parallel position to the latter by means of a drive rod system. The drive rod system 16 comprises a drive rod element 16a, which is guided parallel to the upper wing frame leg on a faceplate 18 and a drive rod element 16b, which is slidably guided on a wing frame leg remote from the axis of rotation by means of a faceplate 20. The two drive rod elements 16a and 16b are connected by a flexible deflection element 10a of the corner deflection 10 for common movement.

For the tilting of the casement, the tilt axis K is formed by the corner bearing E and a tilt bearing 22. The tilting bearing 22 is switched off for the rotary operation about the axis of rotation D and is effective as a tilting bearing for the tilting operation. In tilting operation, the tilt opening width is limited by the rotary slide guide 14.

A frame part 24 is fastened to the frame, which is pivoted about an axis A-A for easier illustration by 90 ° with respect to its actual operating position.

An engagement block 26 is attached to the drive rod element 16a or a horizontal part 10al of the flexible deflection element 10a. This engagement block can be moved back and forth in the direction of movement of the drive rod element 16a along an arrow 28. The engaging element 26 is shown in a TILT READY position 26a, a SPLIT TILT position 26b, a ROTATE position 26c and a CLOSING LOCK position 26d. In the READY-TO-TAKE position 26a of the engagement element 26, the tilting bearing 22 is effective and forms the tilting axis K together with the corner bearing E. The engagement block 26 can be approached in this position 26a through an opening 30 in the fitting part 24 against a stop edge 32. When the locking block 26 stops against the stop edge 32, the casement is not completely closed. To tilt the casement, the opening arm 12 is released from its position relative to the upper casement leg, so that it can be tilted to a position which is determined by the interaction of the extension arm 12 with the rotary slide guide. In this state, the manual control handle 34 assigned to the drive rod system 16 assumes the position 34a according to FIG. 2.

1 that a vertical section of the flexible corner deflection element 10a is designated 10a2.

Furthermore, the following should also be pointed out: the manual actuation element is connected to the drive rod system in such a way that the positions of the manual actuation element 34, which can be formed, for example, by latching points in the pivot bearing which can be overcome, are precisely matched to the range of motion of the engagement element 26.

If the manual operating handle is pivoted through 45 ° into the position 34b according to FIG. 2, the drive rod system 16 is shifted; the drive rod element 16b moves upwards and the drive rod element 16a moves to the right, so that the engagement block 26 reaches the position 26b according to FIG. 1. During this transition of the engagement block 26 from the position 26a to the position 26b, it runs along the stop edge 32 and thus reaches a fork position between the stop edge 32 and a locking tab 36, which belongs to the fitting part 24. It has already been said above that the stop edge 32 does not allow the casement to be closed completely. The stop edge 32 also has this function when the engagement block 26 is forked in a position 26b between the stop edge 32 and the locking tabs 36 in an essentially immovable manner. The casement is then secured against complete closing and against further opening by the interaction of the stop edge 32 and the locking tab 36. One speaks of a SPALTKIPP position, in which between the The sash and the frame remain a small tilting gap, which allows a slight permanent ventilation of the respective room. It is understood that in this SPALTKIPP position, the tilt bearing 22 is still effective and the fixing of the extension arm 12 on the upper wing frame leg is still canceled.

By pivoting the manual control handle 34 into the position 34c, according to FIG. 2, the engagement block 26 reaches the position 26c of FIG. 1. In this position of the engagement block 26, which is based on a corresponding adjustment of the drive rod system 16, the engagement block is out of the range of the locking tab 36 so that the sash can be completely closed and, on the other hand, can be opened for rotation by rotating about the axis of rotation D. It must be assumed that the tilting bearing 22 has been released in the course of the displacement of the drive rod system and that the extension arm 12 has been fixed on the sash frame is. The casement can then be opened as far as the respective reveal of the window frame allows.

When the manual control handle 34 is finally pivoted through a further 90 ° into the position 34d according to FIG. 2, the engagement block 26 moves into the position 26d due to a further displacement of the drive rod system 16. The engagement block can then engage with a locking locking part of the upper frame, which is either attached separately from the fitting part 24 on the upper frame leg or in turn belongs to a part of the fitting part 24, as is shown in EP-B1 51 309 in FIG 12 is shown. The sash is then pressed tightly against the frame. However, this is only one way of locking the door. Another way of locking the lock, which is more important for the present invention, is as follows: ultimately by moving the manual control handle 34 from position 34a via positions 34b and 34c to position 34d, the tip of an engaging element 38 reaches positions 38a, 38b, 38c and 38d.

While in position 38c the tip of the engagement element 38 is still below the upper faceplate leg 10d of the corner deflection 10 and allows the wing frame to be opened and closed, in position 38d the tip of the engagement element 38 protrudes upward above the top faceplate leg 10d of the corner deflection 10 . Provided that the sash has been brought from the rotary operation setting according to the operating position 34c of the manual operating handle 34 into the closed position, the tip of the engagement element 38 engages in a hexagonal hole 40 of a rotating body 42 when the engagement element 38 changes from the position 38c to the position 38d. which is stiffly rotatably mounted in the frame part 24 fitting part. The tip of the engaging element 38 is chamfered in such a way that, in conjunction with a boundary edge 44a of the inner peripheral surface 44 of the hole 40, it causes the sash to be pressed against the frame, possibly with compression of a seal arranged between the sash and frame.

In order to adjust the sealing pressure according to the desired sealing effect and taking into account the dimensional deviations of the sash frame and frame as well as the installation tolerances of the fitting parts, the rotating body 42 can be rotated in the bearing bore of the fitting part 24 receiving it by means of an Allen key. Since the inner circumferential surface 44 is arranged eccentrically with respect to the axis of rotation of the rotating body 42 in the fitting part 24, different engagement surfaces 44a, 44a1 etc. come into engagement position for the engagement of the engagement element 38, so that the sealing pressure can be changed by shifting the engagement edges 44a, 44a1 in the direction of arrow N.

It depends on an exact setting of the fitting part 24 in the direction of arrow 46 with respect to the adjustment range of the engagement block 26. The adjustment range of the engagement block 26 is predetermined by an elongated hole in the upper faceplate leg 10d of the corner deflection 10. The two axially spaced ends of this elongated hole are shown and designated 48a and 48d. These two ends 48a and 48d define the range of motion of the engagement block 26. In order to be able to bring this range of motion and the positions 26a to 26d of the engagement block 26 which are fixed within this range of motion into a desired position in relation to the fitting part 24, the fitting part 24 is freely movable in the direction of the double arrow 46. An adjustment funnel 50 is attached to the fitting part 24. An adjustment strip 52 is attached to the upper horizontal faceplate part 10d of the corner deflection 10. When the sash frame approaches the frame, this adjustment bar 52 moves into the adjustment funnel 50 and in the process inevitably brings the fitting part 24 on the frame part into a desired position, ie into a position in which the movement range 48a to 48d of the engaging block 26 unambiguously to the position of the fitting part 24 is coordinated. If the engaging block 26 then assumes one of the positions 26a to 26c within its range of movement 48a to 48d, the respective position is clearly adapted to the shape and dimensioning of the fitting part 24 on the frame side, as in FIG. 1 by the vertical connecting lines between the block positions 26a to 26c and the fitting part 24 on the frame side. The displaceability of the frame part 24 fitting part is given by the fact that fastening screws 54 abut against stop sleeves, not shown in Fig. 1, when they are tightened before they the fitting part 24, through whose elongated holes 56 these stop sleeves pass, could jam against the frame.

It can be seen from FIG. 1 that the width d of the engagement element 38 in the direction of movement of the drive rod element 16a or of the horizontal section 10a1 of the flexible deflection element 10a is substantially smaller than the width of the engagement surface 44a or 44a1. Therefore, the correct interaction of the engaging element 38 with the inner circumferential surface 44 of the rotating body 42 is ensured under all circumstances regardless of any dimensional deviations of the engaging element 38 with respect to the movement area 48a-48d of the other engaging element 26.

In Fig. 1, a fitting part 24 is shown, which is doubled symmetrically with respect to its longitudinal center LM. This has the advantage that the fitting part 24, as shown in FIG. 1, can be used for the right-hand stop according to FIG. 1, but also for the left-hand stop.

If this leads to difficulties with the fold design of the frame rebate, in which the fitting part 24 is preferably accommodated, the fitting part 24 on the frame side can also be shortened, as shown in FIG. 4. For example, 24 predetermined breaking points can be provided on the fitting part, for example at 58 and 58 ', which each allow different cuts for the left-hand and right-hand hinges.

3 shows details of the fitting part 24 in connection with an upper frame leg 60. Here one can see the stop sleeves 62 mentioned above, through which the screws 54 are passed. The stop sleeves 62 can be supported on the wing frame leg 60, while the screws 54 with engagement feet can be screwed, which can be inserted into a profile groove 64 of the upper frame leg 60 from one end or can also be screwed in like a bayonet. Otherwise, the arrangement of the fitting part 24 on the frame side in FIG. 3 corresponds to the design of the part 24 with the same designation according to FIG. 1.

The fitting part 124 according to FIG. 5 represents a modification compared to the embodiment 24 according to FIGS. 1 and 4. Analog parts are provided with the same reference numerals as there. It can be seen that in this embodiment two rotating bodies 142 and 142 'are provided on both sides of the longitudinal center LM. This fitting part 124 on the frame side is particularly suitable for a double casement window, as shown in FIG. 6. The double casement window 168 there comprises a window frame 170 and two casement frames 172 and 172 '. The sash 172 is referred to as the primary sash, the sash 172 'as the secondary sash. The sash 172 can be configured exactly as described with reference to FIG. 1. It can be rotated about a primary axis of rotation D and can be adjusted in exactly the same way to a tilt-ready state, a gap-tilting state, a rotating opening state and a closed locking state as indicated in FIG. 1 by the reference symbols 26a to 26d and in FIG. 2 by the reference symbols 34a to 34d. The design of the locking elements 26 and 38 can in turn be exactly as shown in FIG. 1. The wing frame 172 is called the primary wing frame because, because of a corresponding rollover bar that overlaps the secondary wing frame 172 ', it must always be opened first before the secondary wing frame 172' can be opened for rotation about the secondary axis of rotation D '. Often one can meet the ventilation needs simply by only turning the primary sash 172 about its axis of rotation D in the ROTATION OPEN position or also about its axis of tilt K in the TILT position or SPALTKIPP position brings, as has been described in detail in connection with FIG. 1.

The secondary casement 172 'must, if it is to remain in the locking state when the primary casement 172 is open, be provided with similar or identical engagement elements 38 at least at the top as described and drawn for the casement there in FIG. 1. If both sashes 172 and 172 'are now equipped with engagement elements of the type shown at 38 in FIG. 1, it is advisable to provide the two rotating bodies 142 and 142' shown in FIG. 5 for receiving the two engagement elements. These can now be attached to one and the same fitting part 124, namely immovable relative to one another in the longitudinal direction 146 of this fitting part. In this case, the large length of the engagement surfaces 144a proves to be particularly helpful. Although the fitting part 124 is namely adjusted in the direction of the double arrow 146 by the interaction of the adjustment bar 52 and the adjustment funnel 50 (see FIG. 1), the relatively large length of the engagement surface 144a in the rotating body 142 'allows undisturbed engagement between this rotating body 142 'and an engaging element associated with the secondary sash 172' of the type shown at 38 in FIG. 1.

It should not be excluded, however, that the two parts of the frame part 124 on the right and left of the longitudinal center shown in FIG. 5 independently of one another each by the adjustment funnel 150 and an adjustment funnel 150 'in cooperation with associated adjustment strips of the type shown in FIG. 1 adjustment bar 52 shown are adjusted. For example, the two halves of the fitting part 124 on the frame side, which are designated by 125 and 125 'in FIG. 5, can each be arranged on a common base plate so as to be displaceable, of course then a butt joint of sufficient size must be provided between the two halves 125 and 125 '. In this case, it is even conceivable to be able to bring each of the two casement frames 172 and 172 'optionally into one of the states of tilt range shaft, split tilt, readiness to turn and locking. As a rule, however, it is sufficient to design the sash 172 'only for rotary opening operation and to allow only the primary sash 172 the various states mentioned above. Between the two sash 172 and 172 'a frame leg fixed to the frame is preferably not attached. It is precisely for this reason that it is necessary to be able to lock the secondary wing frame 172 'in the CLOSED position by means of engagement elements in the manner of the engagement element 38 of FIG. 1.

The inclined edge, which can be seen in all the figures and is labeled 37 in FIG. 1, serves as the leading edge for the engagement block 26 when it comes from the OPENING position 26c to the SPALTKIPP position 26b. The casement is then inevitably lifted from the frame into the SPALTKIPP position.

10. A fitting according to claim 8 or claim 9, characterised in that the adjusting faces (50, 52) are formed of a pair consisting of an adjusting funnel (50) and an adjusting strip (52).
11. A fitting according to claim 10, characterised in that the adjusting funnel (50) is attached to the frame-side fitting portion (24) and the adjusting strip (52) is fixedly associated with the range of movement (48a-48d) of the first engagement member (26).
12. A fitting according to any one of claims 1 to 11, characterised in that the second engagement means (42) are formed of a rotary member (42), which is mounted in the frame-side fitting portion (24) so as to be fastenable and rotatable about an axis parallel to the direction of movement of the second connecting rod member (16b, 10a2) and in that this rotary member (42) comprises an internal circumference engagement face (44) lying eccentrically with respect to its axis of rotation.
13. A fitting according to claim 12, characterised in that the internal circumference engagement face (44) has a polygonal contour.
14. A fitting according to either one of claims 12 and 13, characterised in that the cross-sectional extension of the internal circumference engagement face (44a) is substantially greater in the direction of movement of the first push rod member (16a, 10a1), irrespective of the position of rotation, than the extension (d) of the second engagement member (38) in this direction.
15. A fitting according to any one of claims 12 to 14, characterised in that the rotary member (42) may be fastened in the frame-side fitting portion (24) by friction.
16. A fitting according to any one of claims 12 to 15, characterised in that the internal circumference engagement face (44) is constructed to engage with a cross-section corresponding to an arbor.
17. A fitting according to any one of claims 1 to 16, characterised in that the frame-side fitting portion (24) is symmetrically duplicated with respect to a longitudinal centre (LM) in the direction of movement of the first connecting rod member (16a, 10a1).
18. A fitting according to claim 17, characterised in that the axis of the rotary member (42) lies in the longitudinal centre (LM) of the frame-side fitting portion (24).
19. A fitting according to any one of claims 1 to 18 for use in double casement windows, which comprise a primary casement (172) rotatable about a vertical primary axis of rotation (D) and a secondary casement (172') rotatable about a vertical secondary axis of rotation (D'), a primary fitting portion group being associated with the primary casement (172) and a secondary fitting portion group being associated with the secondary casement (172'), and, in addition, the primary fitting portion group and the secondary fitting portion group each comprising a second engagement member (38) for movement along a vertical primary casement leg remote from the primary axis of rotation or for movement along a secondary casement leg remote from the secondary axis of rotation, characterised in that at least the primary fitting portion group provides, in addition to the close-and-lock and turn readiness states, a part-tilt state and optionally a tilt readiness state through appropriate movement of the respective push rod system and in that a common, frame-side fitting portion (124) with engagement means (142, 142') for the respective second engagement member (38) is associated with the push rod systems of the two fitting portion groups.
20. A fitting according to claim 19, characterised in that the two engagement means (142, 142') of the common fitting portion (124) are arranged near and symmetrically with respect to the longitudinal centre (LM) of the frame-side fitting portion (124) duplicated symmetrically with respect to the longitudinal centre.
