The head piece (53) projecting from the face side (14) has a rear recess. A locking piece is provided in a recess (67) of the hinge section running parallel to the hinge axis (7). The locking piece grips behind the rear recess and arrests the head piece against being pulled out again from the recess (56).

Description

The invention relates to a volume of the type corresponding to the preamble of claim 1.

Such a band is the subject of DE-GM 93 15 327, which belongs to the prior art but is not prepublished. In this band, the spring-loaded pins are arranged perpendicular to the frame or wing surface. The hinge parts of the two hinge parts lie one above the other and are offset from the contact surface of the respective hinge part to the front, ie away from the fastening surface on the frame or the wing, so that a space remains behind the hinge part, through which access to the respective fastening part thereof inner side surface. A tool can be inserted through a hole in this area in the area of the tip of the spring-loaded pin which engages in the fastening part, with the aid of which the tip of the pin can be pushed back and the locking brought about by the pin can be released. The access for the tool, which in turn can be a pin with a beveled, wedge-like front end, is from the area of the shadow groove of the door or window, because the bore runs obliquely forward from the inner side surface of the fastening part away from the fastening surface got to.

The profile systems supplied by the individual manufacturers of the frame profiles for the fixed frame and the sash are quite different in their design and dimensions, so that the inner side face of the fastening part of the respective band part on the frame profiles at quite different locations, seen horizontally, too can come to lie. In some cases, when the inner side surface is far from the adjacent boundary of the shadow groove, the introduction of the release tool for the locking is difficult, if not impossible.

The same problem occurs if not a loosening tool for a spring-loaded pin, but a screw is passed through the oblique hole, which engages in a threaded hole in the cover of the relevant band part or in a T-piece, which has the head in a T- Groove sits on the back of the cover (DE-GM 72 12 721 and 72 13 133. Here too, depending on the position of the inner side surface of the fastening part, the screw head can be difficult to reach.

The invention has for its object to design a tape of the type in question so that it does not matter for the manufacture or for releasing the locking on the position of the tape relative to the profile system.

This object is achieved by the invention reproduced in claim 1.

The retaining pin is inserted into the recess of the hinge part parallel to the contact surface with the same movement, which leads to the engagement of the engagement arrangement on the other leg of the cover, and there provides the undercut on which the locking part, which can be inserted parallel to the hinge pin, into the hinge part is attacking. Access from the back of the band, which would have to take into account the position of the band in relation to the shadow groove, is not necessary. The cover is through the positive engagement of the locking piece on the retaining pin held positive and safe.

One holding pin is normally sufficient for each band part, but there could also be two or even more that could be engaged by the same locking piece.

The undercut is formed in the preferred embodiment according to claim 2 by a circumferential groove of the head part of the holding pin, because then it does not matter to a specific rotational position of the holding pin.

In particular, the undercut can be designed according to claim 3, which is particularly important in connection with the design of the locking piece according to claims 4 and 5, because namely the cylindrical pin nestles into the circumferential groove and there is an extensive contact and fixing zone. To increase the security of the fixing of the cover, the locking piece can have two cylindrical pins which engage on opposite sides in the circumferential groove of the holding pin.

An expedient development according to claim 7 provides for the locking piece to be formed by designing the cover cap for the hinge part, which is already present.

Even if the pins of the cover cap should fit snugly into the corresponding recesses and a removal of the cover that unlocks the cover is difficult, there is nevertheless an increase in security if the pins serving for the locking and engaging on the holding pin are separated from the cover cap and are formed as previously to be inserted, not falling out of themselves again, that is to say tightly seated in the recesses (claim 8).

In many cases, the hinge pins are arranged in the hinge part in a hinge pin sleeve which is arranged in a cylindrical bore of the hinge part and whose bore receiving the hinge pin is arranged eccentrically to its outer circumference. This results in the possibility of adjusting the hinge pin opposite the hinge part. To fix the hinge pin bushing in a certain rotational position, the hinge pin bushing has axially parallel recesses on the outer circumference, into which projections engage. These projections can be integrated in the cover cap in the manner set out in claim 9.

Claim 10 specifies an expedient arrangement of the rotary fixing pin.

The subject of claim 11 is another embodiment of the locking piece in the form of a spring rail, which has the advantage that it is tightly slidably arranged in the frame hinge part under spring tension and can not be lost and also, since it is made of steel, a special resistance to pulling out of the retaining pin when attempting to break open the cover by force.

The embodiment according to claim 12 serves to be able to insert the spring rail into the frame hinge part even before the strap is fastened, whereby it is captively caught by the spring action. When the fastening has been carried out, the cover plate with the retaining pin can be positioned in place because the notched areas are at the level of the retaining pin. Then, when the spring rail is pushed in completely, the central, non-notched area enters the circumferential groove of the retaining pin and lies behind the undercut formed there. The retaining pin can no longer be pulled out.

In order to increase the resistance when trying to pull out the holding pin by force, it is advisable to flare the area of the leg there by 180 °, so that the double tape thickness is available.

The design of the circumferential groove also serves to increase the holding force.

The holding pin can be fixed in any way in the cover part, for example pressed in or held by a cross pin. The safest and also technically The simplest embodiment, however, is to design the holding pin as a screw pin, which is screwed with its foot part into the end face of one leg of the cover (claim 15).

In Fig. 1, a fixed frame 1 and a sash 2 can be seen, which may for example consist of aluminum profiles and are only indicated schematically. They are pivotally connected to one another by a band 100. The hinge 100 comprises a frame hinge part 10 and a wing hinge part 20 which are pivotally connected to one another by a hinge pin 30 with a vertical hinge axis 7. Designations such as "horizontal", "vertical" etc. always refer to the installation position of the belt. As can be seen from FIG. 1, the wing hinge part 2O is supported on the frame hinge part 10 via a weight-transmitting and friction-reducing disk 41. The hinge pin 3O is mounted in the frame hinge part 1O in a non-rotating hinge pin bushing 4O and continues in the wing hinge part 2O and is held in a rotationally fixed manner therein.

The frame hinge part 10 comprises a fastening part 4 which bears against the front vertical flat fastening surface 3 of the fixed frame 1 and which accordingly has a rear flat contact surface 5 which bears against the fastening surface 3. A hinge part 6 is connected in one piece to the fastening part 4 and is horizontally offset with respect to the fastening part 4 and has a cylindrical recess 9 in which the hinge pin 30 is arranged in the eccentric hinge pin bushing 40, i.e. the cylindrical outer circumferential surface and the cylindrical inner circumferential surface of the hinge pin bushing 4O have axes offset laterally relative to one another by the amount of the eccentricity. Depending on the rotational position of the hinge pin bushing 4O, this can be adjusted. The hinge part 6 is also in front of the fastening part 4, i.e. away from the mounting surface 3, and stands in the middle with its back from the mounting surface 3 by the distance 8 (Fig. 2).

In the exemplary embodiment, the fastening part 4 has an approximately rectangular cross section with a flat one the contact surface 5 parallel front 11, against which a cover designated as a whole with 12 abuts with its flat back 13.

The parts 4, 6, on the one hand, and 12, on the other hand, are extruded from an aluminum material, the extrusion direction according to FIG. 3 running perpendicular to the plane of the drawing, so that the parts in the height direction (in the assembled state) have a constant cross section that is predetermined by the manufacture.

The cover 12 is formed in the exemplary embodiment as an angle piece with the legs 12 'and 12' '. The leg 12 ′ assigned to the front side 13 of the fastening part 4 has approximately the cross section of a right-angled triangle, one catheter of which forms the end face 14 of the cover 12 facing the hinge pin 30. The outer edge of the end face 14 engages under a projection 18 of the hinge part 6 or band part 10, so that the cover 12 is supported against being lifted off the front side 11 of the fastening part 4.

The band parts 10, 20 are fastened by means of fastening screws 15, which have a head and, in the exemplary embodiment, are designed as internal polygonal screws. They are screwed from the front through the fastening part 4 into threaded bushes or threaded parts, not shown, inside the profile forming the fixed frame 1, which sit from the inside against the back of the profile wall forming the fastening surface 3. So-called centering bushings 36, which surround the fastening screws 15 and engage both in the frame 1 and in the fastening part 4, serve to fix the frame hinge part 10 on the fixed frame 1 parallel to the fastening surface 3.

Normally, the leg 12 ′ of the cover 12 would be sufficient to cover the heads of the fastening screws 15. However, it would be possible to penetrate between the surfaces 11 and 13 from the left with a tool according to FIG. 2 and large destructive ones because of the large lever arm To exercise powers. For this reason, the cover 12 is pulled around the fastening part 4 and, with its other leg 12 ″ running essentially at right angles to the leg 12 ′, covers the outer side surface 19 of the fastening part 4. As a result, there is no deep gap between the cover that can be reached from the front 12 and the fastening part 4 given more. Near the free edge of the leg 12 ″ extends parallel to this an edge rib 22 which engages in a corresponding groove 23 of the fastening part 4. The elements 22, 23 form an engagement arrangement which can be brought into operation from the left by pushing on the cover according to FIGS. 1 to 3. The upper edge of the end face 14 engages under the projection 18 of the hinge part 6 by the same sliding movement.

However, in order to completely fix the cover 12, there is still a need to secure the cover 12 from being pulled out to the left in accordance with FIGS. 1 to 3 and to secure it in the vertical direction, i.e. 2 perpendicular to the plane of the drawing.

A holding pin, designated as a whole by 50, is used for this purpose, which is arranged with an axis perpendicular to the end face 14 in a recess 21 of the end face. The recess 21 is a threaded hole into which the holding pin 50 is screwed with its screw shaft 51 until it abuts the collar 52 (FIG. 4). The holding pin 50 has a head part 53 with which it protrudes from the end face 14. In this head part there is a circumferential groove 54, the cross section of which is a circular section in a plane passing through the axis of the holding pin. As can be seen from FIG. 4, the circle has its center at 55 slightly outside the circumference of the head part 53.

The head part 53 engages in a recess 56 in the form of a transverse bore in the part of the hinge part 6 opposite the end face 14, which extends from the outside to the cylindrical recess 9.

The hinge part 6 is covered on its free, lower end face according to FIG. 1 by a cover cap, designated as a whole by 60, which forms a locking piece and which has a plate-shaped cover part 61, which in plan corresponds to the outline of the hinge part 6, and cylindrical protruding from it vertically has parallel pins 62, which are located in the cover cap inserted in the manner shown in FIG. 1 with their upper end face 63 above the holding pin 50. The diameter of the cylindrical pin 62 corresponds to the diameter of the circular section which forms the cross section of the circumferential groove 54. The pins 62 are also at such a clear distance from one another that they just fit into the circumferential groove 54, as indicated in FIGS. 4 and 6.

As can be seen from FIGS. 1 and 5, the pins 62 are arranged laterally on the cover part 61, so that when they are inserted into corresponding cylindrical recesses 67 of the hinge part 6 parallel to the hinge axis 7 they just pass the hinge pin bushing 40. The insertion of the pin 62 into the recesses 67 is tight, so that the cover 60 is firmly seated on the hinge part 6. Between the pin 62 is a shorter, when the cover cap 60 is inserted the retaining pin 50 does not reach the rotary fixing pin 64, which projects somewhat radially into the interior of the recess 9 and engages in one of the axially parallel grooves or grooves 65 provided on the outer circumference of the hinge pin bushing, so that the hinge pin bushing 40 can then no longer rotate. The pins 62, 64, 62 are integrally connected to one another along axially parallel surface lines, so that the pin arrangement is given increased stability. There are several grooves 65 distributed over the circumference of the hinge pin bushing 40 so that it can be fixed in different rotational positions. In the middle, the cover cap 60 has a cylindrical projection 66, which sits against the underside of the hinge pin 30 and this in one holds certain altitude.

1, the two pins 62 engage in the circumferential groove 54 of the projecting head part 53 of the holding pin 50 and lock the holding pin 50 in its axial direction and thus also the cover 12 both in its slide-open direction parallel to that Front 11 as well as perpendicular to it in the direction of the hinge pin 30.

8 shows a cover cap 70 with pins 72, 72 which can be pushed tightly into the recesses 67 and which do not extend into the region of the holding pin 50. Rather, separate pins 62 ', 62' extend here, which bring about the locking and have been pushed tightly into the recesses 67 in front of the cover cap 70, so that they do not fall out by themselves. Length and insertion depth are dimensioned so that the holding pin 50 is reached in any case. The pins 62 ', 62' can also occupy the entire remaining height of the band part 10. They can consist of plastic or metal and can be designed, for example, as grooved pins. Since they are stuck in the recesses 67, the locking of the cover 12 is not released even if a burglar should succeed in removing the cover cap 70.

Another band 100 'is shown in FIGS. 9 to 15, in which the locking piece is formed by a spring rail 80.

The holding pin 50 'is again provided with a thread and has at its end facing the hinge pin 30 or the hinge pin bushing 40 a circumferential groove 73 with an outer, i.e. Flank 74 facing away from thread 51 and perpendicular to the axis of holding pin 50 '. A kind of screw head 78 is formed by the circumferential groove.

In the band part 10, a groove 75 of U-shaped cross section, which runs parallel to the axis of the recess 9 and runs through the height of the band part 10 and is open towards the recess 9, is attached to the recess for the band journal bushing 40. The groove 75 intersects the cross hole 56 in the band part 10. The mutually parallel legs 75 ', 75''or their line of symmetry 76 form an angle 77 with the axis of the holding pin 50', which in the exemplary embodiment is approximately 60 °.

In the groove 75 there is a spring rail 80 of the same, i.e. U-shaped cross section arranged, which can be pushed tightly into the groove 75 parallel to the axis of the hinge pin 30. The spring rail 80 is as high as the band part 10.

As can be seen particularly from FIG. 14, the one U-leg 80 'of the spring rail 80 is not complete, but only in the central region 82 about as long as the other leg 80' '. The central region 82 is located where the retaining pin 50 'is located when the spring rail 80 is pushed into the band part 10. 14, the areas 83 adjacent to the central area 82 on both sides in the longitudinal direction of the spring rail 80 are notched. The reason for this can be seen from FIGS. 12 and 13. In Fig. 12, the spring rail 80 is not fully inserted. At the height of the holding pin 50 'is the notched area 83, the edge of which does not reach the circumferential groove 73 of the holding pin 50', so that the holding pin 50 'can be pushed in and pulled out.

If, however, the spring rail 80 is pushed in completely (FIG. 13), the not-released area 82, which thus protrudes as far as the other leg 80 ″ (see FIG. 14), engages in the circumferential groove 73 and locks under contact on the flank 74 forming an undercut, the holding pin 50 ′ against being pulled out in the direction of the arrow 79 according to FIG. 10.

In order to increase the stability in the engagement area, the leg 80 'has a flange 81 in the central area 82 by 180 °, ie a double. This doubling, as can be seen from FIG. 10, extends somewhat into the bore 57 via the flank 75 ′ of the groove and engages behind the undercut 74 or the head 78 there, which has the same diameter as the threaded part 51. When stressed in the direction of arrow 79, the spring rail 8O is blocked against slipping out of the circumferential groove 73 in that the opposite leg 80 ″ lies with its edge 80 ″ ″ against the outer circumference of the hinge pin bush 40.

When the spring rail is fully inserted, it is covered from below by the cover cap 71 (FIG. 11), from above by the wing hinge part 20. When the wing hinge part 20 is fully open, the longitudinal groove 75 is accessible from the outside, so that the spring rail 80 can be inserted into the spring with a pin-like tool 12 can be brought into the position shown in which the holding pin 50 'can be pulled out with the cover 12. In order to be able to easily reach the spring rail 80 with the pin and also for the purpose of increasing the spring tension, small domes 84 protruding into the cross section are formed at the ends in the base of the U-shaped cross section of the spring rail 80.
