Said door leaf (2) is connected to the frame via hinges (5), each having at least three hinge blades (8, 9) which a hinge bolt (4) traverses. Sliding rings (12) are preferably arranged in particular to rotate in unison with those end surfaces of the hinge blades which face each other. The design of said door is such that for the purpose of particularly simple manipulation for the required height displacement of the door leaf (2) in the frame (3), the door leaf (2) is formed to be displaceable in relation to the frame (3) by approximately up to the height of one flank fold of the door leaf in the region of the hinges (5) in the longitudinal direction of the bolt, and can be fastened, optionally in one of the displacement end positions, to pivot about the hinge bolts (4) without dismantling or altering the hinge parts (4, 8, 9).

Description

The invention relates to a door, in particular a fire door, with a frame and an optionally right or left hinged, with respect to a horizontal one In this respect, the central plane is approximately symmetrical on the long side areas and at least one of the broadside areas with one in the closed state that of the in Opening towards the wide side of the gap to the frame frame covering rebated door leaf, which is connected to the frame frame via hinges is, each of which at least three hinge straps penetrated by a hinge pin has, the band tab alternately seen in the longitudinal direction of the bolt connected to a longitudinal side area of the door leaf and a vertical bar of the frame frame are and on their mutually facing end faces preferably sliding rings, in particular non-rotatably arranged.

Doors of the type in question are known from DE-A-16 83 419 and are for the right-handed or left-hinged Installation as a whole consisting of door leaf and frame frame from one installation type to the other rotated by 180 °. The frame rebate on the bottom in the respective installation position removed, so that the bottom can just finish with the bottom side rail. at door leaf folded only on the long side, the door leaf sides of which run vertically in both installation positions are flat, the optional left-right installation poses no problems. there it is known to mount the handle set in adaptation to the chosen installation; the openings in the door leaf required for this are prefabricated. In such Doors, it is still commonplace that the lower hinge supports the axial load of the Door leaf takes up, while the upper hinge in this respect only management tasks occupies because an equal load of both hinges among those to be considered here Conditions technically not achievable. The hinge straps must therefore, the functions mentioned above are sufficient in both installation directions. Among the occurring loads are regular in the two connection areas between the Sliding rings on the door leaf side and the frame-side hinge bands are provided, which are designed to be resistant enough to reduce wear are. All hinge straps are so right and right for both directions left-hinged installation prepared.

If you want to use a door leaf for such a door, next to its longitudinal folds also formed with at least one broad-sided fold, preferably folded on all sides is, so that in both installation positions in addition to the longitudinal engagement gaps also the upper one of the door leaf to the frame frame are covered, then there is a protruding downward Rebate the door leaf beyond the bottom side rail. Therefore the Frame frame slightly larger than the door leaf, so that the door leaf in Frame frame can be moved in the vertical direction so that the protruding on the bottom There is space for the fold towards the floor.

The invention has for its object a door of the type mentioned with existing Hinge connections between the one long side of the door leaf and the a vertical frame spar for optional installation with left or right hinged Door leaf with regard to the required height adjustability of the door leaf in to make the frame frame particularly easy to handle.

This is achieved according to the invention in that the door leaf opposite the frame frame by up to the height of a broad-sided fold of the door leaf in the area of Hinges can be moved in the longitudinal direction of the bolt and without removing or converting of hinge parts optionally in one of the sliding end positions Hinge pin can be pivotally fixed.

In a first embodiment, this is achieved in that the middle hinge band each hinge by about its hinge straps up to the height of a wide-sided rebate of the door leaf with a corresponding free space is designed to be displaceable along the hinge pin and that on the hinge pin for fixing the required final displacement position laterally slidable, annular spacer is provided, the thickness corresponds to the free space and that for receiving the hinge pin a U-shaped Has inner profile and a circular segment-shaped outer profile, the segment ends run out in the free ends of the legs of the inner profile.

The spacer is in particular designed such that the distance between the legs of the U-shaped inner profile of the spacer little larger than that Diameter of the hinge pin is that the web-side transition between the Legs is formed as a semicircle, the center of the circle in the inserted state of the Spacer lies in the longitudinal axis of the hinge pin, and that the diameter of the circular segment-shaped outer profile, the center of the circle in the inserted state lies in the longitudinal axis of the hinge pin, larger than that of the adjacent Belt rolls or the slip rings used in them.

Furthermore, the design of the spacer is preferably such that at least one of the two end faces, preferably the lower one in the inserted state, the spacer is a segment of a circle seen in terms of its outer dimension Undercut is formed in the inserted state of the spacer the end face or sides of the adjacent band rolls facing this or the slide ring or rings arranged there under the load of the door leaf engages or intervenes so that the spacer slides out of its inserted position prevented by the intervention (s) with the neighboring sliding ring (s) is as soon as the door leaf is supported on the spacer.

In an even more preferred embodiment, the training is such that the Undercut or one of the undercuts of the spacer, preferably the one facing downwards in the operating state is provided with an intervention training is that with a counter training in the adjacent end face of the neighboring Belt roll or the sliding ring arranged there under the load of the door leaf in torsion-proof Intervention occurs, in particular in the form of two parallel symmetrical opposite shoulders in the area to the longitudinal axis of the hinge pin the undercut, on which two equally arranged edges of circular sections of the adjacent slide ring, with the shoulders in the undercut the spacer preferably to the opposite sides of the inner profile run parallel and the shoulders in the circular segment circumferential surface of the outer profile can leak if the spacer on its opposite Front also has an undercut. This will prevents the spacer from facing the frame-side hinge or its sliding ring can rotate so that the circumferential opening of the U-shaped Inner profile does not come into view of the beholder. The slide ring of each load-bearing frame-side band is - like all slide rings - torsion-proof connected to the band roll of the associated hinge band, in particular by that the sliding rings with stub provided on them in the tape rolls are pressed in. For reasons of wear, the sliding rings are preferred made of hardened material and / or the spacers made of sintered metal.

After choosing the type of installation, the door leaf is opened opposite the frame whose upper cross member is shifted and thereby fixed in this final displacement position, that the spacer in the resulting free space from the side pushes on the hinge pin, the one seen in the longitudinal direction of the pin Dimension practically fills the free space and, moreover, in terms of its shape According to the measures outlined, it can be taken so that it is in its insertion position do not leave it unintentionally and / or turn its direction to the frame underneath the occurring loads are not changed. This can result from the insertion position Spacer even when performing the shoulders effective against turning up to then do not remove its outer periphery when the spacer is attached to its two end faces directed in the longitudinal direction of the hinge pin with undercuts is provided because then the one that does not have the gradations is the lateral one Evasion of the spacer prevented by engagement of the associated ring. However, the execution of the shoulder is preferably not to the periphery, but rather only to the inner edge of the undercut, so that in the direction of the inner profile a protruding area of the edge between the circular segment External profile and the undercut on both sides of the gap between the legs remains of the inner profile, the lateral evasion of the spacer by attack prevented on the engaging slide ring. So that the spacer can only can be removed if the door leaf is raised in such a way that both the The following sliding ring of the hinge band is released as well as the spacer of the engagement between the shoulders and the straight edges of the slide ring the lower hinge band can be lifted. In this first embodiment becomes the middle hinge band of each hinge with its band tab preferably set on the door leaf.

It can be clearly seen that when the door is turned through 180 °, the same procedure is followed can be.

In a second embodiment, the hinge arrangement is made such that the middle hinge band of at least one, preferably the lowest, hinge in one, preferably in the hinge-side vertical frame spar, band pocket by about the height of a broad-sided fold of the door leaf in the longitudinal direction of the Hinge pin guided slidably and optionally in one of these displacement positions can be supported against the load of the door leaf.

For this purpose, a support member is held displaceably, in particular on the belt pocket optionally on one of two in the longitudinal direction of the hinge pin on both sides of the support member provided support surfaces of the band tab of the middle hinge band attacks, in particular by edge areas of an opening in the band tab, preferably formed as from the edge of the hinge pin facing away from the hinge pin outgoing U-shaped recess on their mutually facing leg sides, are formed, the support member preferably being rotatable in the broad sides of the belt pocket mounted eccentric is formed, the eccentric surface facing away from the eccentric axis of rotation by - especially from outside the band pocket, for example a polygonal design of the eccentric shaft by means of an adapted key - Rotation optionally engages one or the other of the support surfaces, whereby preferably the eccentric surface curved around the eccentric axis of rotation in the form of a segment of a circle is formed and the support surfaces are also curved segment-shaped.

Furthermore, the design of this embodiment is preferably such that the Longitudinal displacement guidance of the band tab within the band pocket by at least an elongated hole engaging projection guide extending in the longitudinal direction of the hinge pin is formed between the belt tab and the belt pocket, in particular with a guide recess in the band tab and one engaging in it opposite the Belt pocket in the direction of displacement fixed projection, which preferably as part of a Inserting the hinge tab into the hinge pocket which becomes effective with one opposite the hinge box housing and thus the vertical frame spar Spring nose resiliently acted against the broad surface of the hinge tab as a projection is formed, which in the latched state has a surface pointing in the opposite direction of insertion the guide recess in the band tab, preferably in the form of one or more longitudinal slot recesses running in the longitudinal direction of the hinge pin, blocking engages behind.

The procedure is preferably such that the belt pocket is in the end region of the insertion section of the hinge flap, a receiving groove that preferably narrows in the direction of insertion for the leading edge of the hinge flap, which the hinge flap in the longitudinal direction of the hinge pin slidably leads, and into the broad sides of the hinge tab between receiving shaft walls open, one of which is resilient on the is applied to adjacent surface of the band tab and part of the snap closure has, in particular the locking lug, which in the engaged state in the opposite direction reaches behind the edge of the elongated hole recess in the band tab, the spring-loaded shaft wall as a single element next to the one used Band tabs inserted in the receiving groove and in this by a small Angle perpendicular to the broad band flap under the force of a spring element, in particular Helical compression spring or spring clip, is pivotable, which is preferred prestressed between the pivotable shaft wall and an adjacent housing wall is, or that the belt pocket in one piece from a sheet metal bent part trained tape pocket housing, which in particular as an individual part on the vertical Zargenholm is fixed, preferably over two of the housing in Struts bracing in the longitudinal direction, the resiliently pivotable Shaft wall in its end area facing away from the insertion gap for the band flap is integrally formed on the bent sheet metal part of the belt pocket housing and its resilient Exposure protruding into the insertion path of the hinge flap relates to the spring properties of the sheet material.

Also in this embodiment is due to a wide-sided fold of the door leaf Frame frame a little higher than the door leaf and the slots in the reach through their rag into the assigned hinge pocket correspondingly wider slots than the band tabs in the pocket and if necessary, their cover on the hinge side. In this embodiment, the middle The hinges of the hinges are preferably provided on the frame side, so that the Hinged pockets can be set inside the vertical frame which the door leaf is pivotally held. The assembly of the height-adjustable hinge is in the associated band pocket by a spring-elastic training Snap lock facilitates the, together with the formation of a receiving groove in the floor the belt pocket ensures the required longitudinal movement and at the same time one Dislocation of the hinge flap to the longitudinal direction of the hinge pin prevented. To For this purpose, the snap lock preferably works with two in the longitudinal direction of the Hinge pin offset locking lugs, each in an associated slot hole engages in the hinge flap, the slot opening the required Taking into account the displacement path between the displacement end positions of the hinge flap correspondingly longer than the same dimension of the engaging latch is. The displacement path between the displacement end positions for the optional Right and left-hinged installation is based on the height dimension of the wide-sided fold adapted to the door leaf, because of the engagement game between the above Cross frame spar and the upper edge of the door leaf box is preferably less than the height dimension of the broad-sided door leaf folds. The fixation of the shift end positions for the displacement movement of the door leaf in the higher trained Zargenfalz that the downwardly projecting door leaf fold with for the door leaf movement required distance above the lower frame spar freed from its stop frame for the right-left-hinged installation is preferred an eccentric, which is preferably in the overall U-shaped recess of the band tab engages so that the band flap is pushed with this recess over the eccentric can be, for the purpose of a simple operation from the outside with a Wrench or the like can be rotated. By training the Eccentric with a peripheral arcuate surface section for the attack the mutually opposite, correspondingly curved support surfaces in the leg area the recess of the hinge tab is achieved that the eccentric in the selected Position of engagement with one of the two support surfaces practically without lateral forces the raised Door leaf bears. The axis of rotation of the eccentric can also be compared to that Lay the support surfaces inside the U-shaped recess, creating a force component in the direction of the end of the U-leg, so that the band tab Support in the groove of the belt pocket and the eccentric against the ground this receiving groove cannot turn away tarnishing.

This makes it easy to adapt the door to the lower one depending on the type of installation "Threshold" reached without hinge straps having to be removed or the Hinge pin must be removed from its position.

This makes it easy to adapt the door to the lower one depending on the type of installation "Threshold" reached without hinge straps having to be removed or the Hinge pin must be removed from its position.

Figure 1a shows a view of the rebate side of the door 1 in one of the two optionally for the right and left hinged installation in the engaged state of the door leaf 2 in the associated, only partially indicated frame 3. With regard to its The horizontal center plane is the door leaf 2 in relation to the hinge straps on the door leaf side 8 of the hinges 5 are symmetrical; the same applies to those to be provided in the door leaf Recesses for receiving the according to the type of attack handle set to be implemented. The same applies to the frame 3 with respect to Hinge tab 9, only depending on the installation position in the floor area Removed rebate of the bottom side rail for a smooth passage becomes. The door leaf 2 is opposite the frame frame 3 in both installation positions moved upwards, whereby between the door leaf-side frame 8 and the below the frame-side hinge 9 there is a space 7 between the only indicated associated hinge pin 4, in which at least in each case hinge 5 located below uses a spacer 17, which will be explained in more detail later is. Compared to a conventional hinge, the middle hinge band is 8 with a clearance corresponding to the free space 7 on the hinge pin 4 displaceable, which is correspondingly longer or between the corresponding extends further apart hinge straps 9 on the frame side.

The vertical sectional view 1b shows the door leaf 2 from a box and one Cover which forms folds 16 projecting downwards and upwards, which are vertical extend broadly of the door leaf, folded accordingly and with a horizontal protruding section connected to the door leaf box - spot welded - is.

The horizontal section according to FIG. 1c shows that the trained in a known manner Door leaf is provided with longitudinal folds 15, which by folding the Cover plates are formed around laterally protruding folds of the door box. This Longitudinal folds 15 protrude further from the door case than the broad folds 16. The hinge bands 8 on the door leaf side are with their band tabs 10 in a known manner connected to the door leaf 2 and form to accommodate the only in terms of his Band rolls 14 provided along the longitudinal axis of the hinge pin 4.

The jumping representation according to FIG. 2 shows one of the hinges 5, which is on the door leaf side with the hinge band 10 to be fixed hinge 8 and the two on the frame side the hinge straps 9 to be fixed comprises 9, which is a one-piece frame-side Form a hinge band. The hinge straps are used after the middle hinge band 8 on the door leaf side between the frame-side hinge bands 9 of a common hinge pin, not shown, in a known manner penetrated. In the end faces of the hinge straps 8 facing each other and 9, slide rings 12 are arranged, each with a nozzle formed thereon 13 engage the associated band rollers 14 in a rotationally fixed manner and on the hinge pin are supported. The middle hinge band 8 is in the installed state between the hinge straps 9 along the hinge pin 4, not shown, by one Free space 7 (Figure 1a) slidable for lifting the door leaf in the respective Installation position is used, so that the downwardly projecting wide-sided fold of the door leaf ends above the floor, as mentioned in connection with FIG. 1a is.

The spacer 17 can be inserted into this free space, perpendicular to the longitudinal axis of the hinge pin can be placed on this, for which the spacer 17 with a is provided in the longitudinal direction of the bolt U-shaped inner profile 18, the Leg 20 a little further than the diameter of the hinge pin from each other are spaced and the web-side transition 21 enclosing the bolt in Profile is semicircular. The spacer 17 has a segment of a circle Outer profile 19 on, insofar as a segment of a circle, as the mouth of the inner profile the circular wall interrupts. The spacer is on both in the longitudinal direction of the bolt seen end faces 22 and 23 provided with undercuts 24 in the the slide rings 12 engage so that in the loaded state of the hinge by the Door leaf a sliding of the spacer 17 from its inserted position on the hinge pin is prevented. Accordingly, the outer wall of the outer profile 19 of the Spacer 17 dimensioned radially larger than the radius of the slide rings in the inserted state 12. The face 23 pointing downward in the respective installed state formed undercut 24 is in diametrically opposite edge regions provided with shoulders 25, the circular segment-shaped outer edge interrupt the undercut in the form of a circular segment, as shown in FIGS. 2 and 3 a-c. The shoulders 25 run parallel to one another and to the inner sides the leg 20 of the U-shaped inner profile 18, with a larger one Distance than that between these inner thighs, so that from the shoulders 25 seen from each a ring segment-shaped elevation area between the outer edge area the undercut 24 and the outer circumference of the segment-shaped Outer profile 19 remains, which ends in the end regions of the legs 20. The slide rings 12 are on diametrically opposed outer peripheral areas Edges 26 provided by circular segment-shaped flats of the outer circumference the slide rings 12 are formed, which run parallel to each other and their distance from each other between the shoulders 25 of the spacer 17 such corresponds to that the edges 26 upon engagement of the respective slide ring 12 in the after engage undercut 24 between shoulders 25 in a rotationally locking manner. Since the slide rings are locked against rotation in their respective assigned unwindings 14, the spacer is thus held in a rotationally secure manner, specifically in the present case Example compared to the frame, because the middle hinge 8 preferred in this Embodiment is set on the door leaf 2. Since the other end face 22nd of the spacer 17 with an undercut 24 without shoulders peripherally in the form of a segment of a circle is circumferentially provided, with its in this undercut Turn the engaging slide ring 12 provided hinge band 8 on the door leaf side freely. The The rotational position of the spacer is determined by the position of the edges 26 of the slide ring concerned 12 and its non-rotatable engagement in the tape roll 14 of the associated Hinged belt 9 set such that the circumferential opening of the U-shaped Inner profile 18 facing the side rail so that this mouth by the user the door is not noticed.

Figures 3 a-c show the spacer 17 enlarged with the previously discussed details. Characterized in that the circular segment circumferential surface 27 of the outer contour 19 to the inside of the thighs reaching out in the ends of the thighs, the shoulders 25 thus the ring segment-shaped area between the circumferential surface 27 and the undercut 24 do not interrupt in this leg end area is the spacer already by this measure of lateral migration from the inserted position prevented. You could also shoulder 25 towards the ends of the legs continue, then the undercut located on the other end face 22 would have to 24 take on this task, which is why in the event of unintentional lifting of the door leaf this bracket of the spacer can already be lost. It should however, only a targeted lifting of the door leaf with the spacer 17 for separation the safe insertion position against migration and twisting, which is why the drawn execution is preferred.

The door according to Figures 1 a-c was regarding the hinge arrangement regarding their hinge band assignments on the first embodiment with end shift setting the door leaf opposite the frame frame using a spacer shown and drawn, in which preferably the middle hinge band 8th is assigned to the door leaf 2. The next is the middle one Hinged band 8 preferably assigned to the frame 3, because in the second Design of the hinge band tabs within a band pocket receiving them is displaceable in the end positions, which in the context of a hinge of the associated hinge is simpler than for two such hinge straps. This reorientation must be taken into account in the following explanations.

FIGS. 4 a-c show a section of the belt pocket 30 Hinges 5 having vertical frame rails 6 with inserted into the band pocket 30 Band tab 10 of the middle hinge band 8 between two hinge bands 9, in a manner not shown on the also not shown Door leaf 2 are attached and the only when passing through only one its center line indicated hinge pin 4 in the usual way and without special distances in their sequence are pivotable against each other. The hinge plate 10 is seen within the longitudinal direction of the hinge pin made wider by about the space required to fit the door leaf 2 the hinge 5 so far that in the respective installation position right or left hinged the downwardly protruding wide fold of the door leaf 2 from the floor in is spaced as required. The left is the Band tab 10 within the band pocket 30 in a lower end shift position, in the middle representation in a neutral transition position of the shift distance and in the right representation in an upper end shift position. The right representation would therefore correspond to an installation position in which the conditions are as drawn. The left representation corresponds to the end position, the band flaps and Take the belt pocket towards each other when you have turned the installation position by 180 ° chooses. In this respect, the representations are only intended to recognize the displacement mechanism to let. The band tab 10 is guided in the direction of displacement by the fact that it with his the associated hinge tab 8 facing away from the front edge 54 in the base of a Recording groove 39 of the belt pocket 30, described below, on the one hand and via slot openings 44 and arranged in the region of the band box 30 one of the longitudinal side 45 engaging detents 43 on the other hand in the longitudinal direction of the hinge pin 4 is guided. The slot openings 44 are correspondingly longer than the area of engagement of the detents 43 around the displacement distance between their end positions, as shown in FIGS. 4 a-c. The band tab 10 has a U-shaped recess 43, in which receives an eccentric 31 when the band tab 10 is inserted into the band pocket 30, which is rotatable about an eccentric axis of rotation 33 and has an eccentric surface 32, seen in profile in the direction of the eccentric axis of rotation 33 around this circular segment is progressive. The eccentric axis of rotation 33 is rotatable between a shaft wall 41 of the belt pocket housing 37 and one resilient in the pocket pivotable shaft wall 40 of the belt pocket 30 in corresponding Bores held - Figure 6 - and on the end face of the end of the eccentric axis of rotation 33, which penetrates the bore in the shaft wall 41, with a multi-edged design 36 provided the attack of a wrench for turning the eccentric from outside the tape pocket 30 is used. Two on the eccentric axis of rotation 33 opposite leg wall areas of the U-shaped recess 34 of the band tab 10 support surfaces 35 are provided, which are in adaptation are curved on the course of the eccentric surface 32. On one of these support surfaces 35 engages the eccentric surface 32, depending on which end of shift position the eccentric 31 is rotated to match the installation position - Figures 4 a and 4 c -, while in a neutral central position the eccentric disengaged from the Support surfaces is - Figure 4 b -. In the respective engagement position - Figures 4 a and 4 c - is the engagement of the eccentric 31 in the respective support surface 35 even when freely rotatable Eccentric under the occurring load from the door leaf 2 practically without transverse forces and therefore stable.

Figure 5 shows an enlarged section through the belt pocket 10 in their arrangement the vertical frame spar 6; the door leaf 2 is only hinted at. Protrudes into the band pocket the band tab 10 of the hinge band 8, as also shown in dashed lines, in a cutting plane that runs through one of the locking lugs 43. The Belt pocket 30 is formed in one piece with respect to its housing 37 as a bent sheet metal part and has an insertion gap 38 for the insertion of the band tab 10. The ligament 10 is inserted through this insertion gap 38 into the belt pocket and engages in this state with its front edge 54 in a receiving groove 39, which in a corresponding bulge of the belt pocket housing 37 is formed. In the receiving groove 39 opens the housing wall 41, along which one broad side of the inserted Hinge flap 10 runs approximately parallel while parallel to the other Broad side of the band tab 10 is a shaft wall 20 which is designed as a single element runs with the foot area adjacent to the front edge 54 of the band tab 10 is also inserted into the receiving groove 39, as can be seen in FIG. 5. The Receiving groove 39 is in the neighboring area of this shaft wall 40 towards the groove bottom narrowed, such that the band tab 10 with its leading edge area insofar as is held free of play in the receiving groove, while the one designed as an individual part Manhole wall 40 at a slight angle from the adjacent broadside of the belt tab 10 is pivotable against the force of a coil spring 46, that between the broad flap 10 facing away from the broadside of the shaft wall 40 and an opposite wall 52 of the belt pocket housing 37 - preferably biased - inserted. Two can also be seen in the spar direction such compression springs 46 may be arranged in parallel. The belt pocket housing 37 lies with of its housing side having the insertion gap 38 on the diaphragm section of the vertical Frame 6 with a helical compression spring running at right angles to it 46 supporting wall at the reveal distance of the spar 6 and is on this attached by tabs 51, as can be seen in Figure 6. The reveal section is with a longitudinal groove for a fire protection strip Mistake. The shaft wall 40 faces for ease of insertion of the band tab 10 has a bend 42. In the vicinity of this turn 42 a catch 43 is bent out of the shaft wall 40 in the direction of the band tab 10, the one facing away from the leading edge 54 in the inserted state of the band tab Surface 45 as the edge of an elongated hole recess 44 of the hinge plate 10 overlaps, as can be seen from FIG. 5 and in connection with FIGS. 4 a to 4 c has already been mentioned. Before inserting the band tab 10 is the Manhole wall 40 under the pressure of the helical compression spring (s) (46) in the insertion path of the flap 10 is pivoted, so that in the course of the insertion process of the band tab 10 first at the turn 42 and then with increasing pivoting of the Manhole wall 40 against the spring pressure on the inclined surfaces pointing in the direction of insertion 53 of the locking lugs 43 until this on the spring-loaded shaft wall 40 slide adjacent broad side of the tab 10 and in the final state of the Insert it into the slot recesses 44. Grips in this state the front edge 54 of the band tab 10 at the bottom of the receiving groove 39, and the The locking surface of the locking lug overlaps the surface 45 practically without play Edge region of the elongated hole recess 44, so that a play-free reception of the Hinge pin 10 with the exception of the displaceability in the longitudinal direction of the hinge pin 4 is given in the belt pocket 30.

Figure 6 shows a slightly different embodiment, in which the belt pocket housing 37 is composed of two housing parts 47 and 48, which in Pulling the housing with two oppositely projecting tabs 51 engage in the reveal section of the vertical beam 6, for example by spot welding. The spring-loaded shaft wall 40 is previously in terms of Outside contour indicated receiving groove 39 of the belt pocket housing 17 is used. Furthermore, the eccentric 31 with its eccentric axis of rotation 33, not shown, through the aligned to the eccentric central opening in the shaft wall 41 of the belt pocket housing 37 and the spring-loaded shaft wall 40 is passed in brought the installation position between these walls, here with one pointing downwards Collar guided in the bore of the shaft wall 40 and between the walls supported. The spring loading of the shaft wall 40 is here instead of Helical compression springs 26 caused by a band-shaped spring clip 49. The Manhole wall 40 is provided with two latching lugs spaced apart in the longitudinal direction of the bar 43 provided, in the locked state in two correspondingly arranged elongated holes 44 engage the hinge tab 10, whereby a snap lock and a part of the sliding guide between the sliding end positions of the hinge 10 is formed in the belt pocket 30, as has already been described. At the Inserting the band tab 10 of the hinge band 8 through the insertion slot 50 of the vertical strut 6 of the band flap passes through the shaft walls 40 and 41 formed insertion shaft. There is a positioning in the end of use as shown in Figure 5.

Figure 7 shows a preferred embodiment of the belt pocket 30 such that there the Shaft wall 40 resiliently pivotable in one piece with the remaining housing wall parts is designed in such a way that the lugs 43 in the insertion shaft for the band tab 10 protrude between the walls 40 and 41 and when inserting the band tab by resilient deformation of this housing wall part - Shaft wall 40 - dodge and when the end use position is reached engage in the slot recesses 44 under spring back, whereby the snap lock is formed as it was described in connection with Figure 5.
