Description

Band assembly for hingedly connecting a wing of a door, window or the like to a frame

The invention relates to a band assembly for hingedly connecting a wing of a door, a window or the like, on a frame, comprising a frame hinge flap comprising a frame fastening part and with a wing hinge part comprising wing hinge tabs, wherein to provide the adjustment possibility of the wing in the frame, the frame attachment part and / or the wing attachment part are arranged to be displaceable relative to the respectively facing attachment surface on the wing or on the frame.

Such a band arrangement is known for example from DE 101 52 366 C5. It comprises a receiving piece which can be fixed in a hollow profile. In the receiving piece guide bores are provided, which continue in perforations in a mounting side forming the profile wall. On the fastening part of the hinge part support pins are provided, which are designed to be inserted into the guide holes and optionally spreadable, so that the determination of the hinge part can be done in the desired position by jamming the support pins in the guide holes. The adjustment of the hinge part relative to the attachment side for the purpose of adjusting the wing in the frame is a threaded element which is fixable on the fastening part in the adjustment direction and has an external thread which can be screwed into a complementary, provided in the receiving piece internal thread.

The disadvantage of this band assembly that it is expensive to manufacture because of the large number of components used. In addition, this band assembly includes no means for securing the wing in its closed position against unauthorized opening, for example by lifting the wing or by expelling the hinged joint between the two hinge tabs producing hinge pin.

The invention is therefore an object of the invention to provide a band assembly, on the one hand, an adjustment of the band portion relative to the mounting surface of a Frame or a wing allowed for the purpose of adjustment and cheaper than the known from DE 101 52 366 C5 known, on the other hand, a violent removal of a closed wing difficult.

This object is achieved by the reproduced in claim 1 band assembly.

In the band assembly of the present invention, the frame hinge flap including the frame attachment part and the wing hinge flap including the wing attachment part are respectively mountable on attachment surfaces of the frame and the wing respectively formed on a narrow side of the wing or the frame. According to the invention, the band arrangement comprises at least one guide member interacting with the frame attachment part and permitting a displacement of the frame band part in the frame plane and / or a guide member guidingly cooperating with the wing attachment part and permitting a displacement of the wing attachment part in the wing plane, so that an adjustment of the wing in the frame in the frame or wing level - also called horizontal adjustment - is possible. Furthermore, the band arrangement according to the invention comprises at least one adjusting device for displacing and fixing the frame fastening part in the frame plane or the wing fastening part in the wing plane, wherein the adjusting device may comprise an adjusting member having a threaded shank and a radial projection, wherein the threaded shaft with a complementary thread on the Frame and wings and the radial projection are engageable with a receptacle on the frame or Flügelbefestigungsteil.

In addition, for the purpose of securing the closed leaf, at least a part of the guide members is provided with a protruding head which, with the wing closed, projects into an opening provided on the respective other part - the frame or the wing. In this way, when the wing is closed on the opposite side of the head, a positive connection between the wing and the frame, so that removal of the wing even after the hinge joint connection between the two hinge tabs - for example by expelling the hinge pin - is not possible. The guide pins are preferably arranged such that the associated openings, in which they engage in the closed state of the wing, do not penetrate into the fastening part of the respective other hinge strap, so that it is not weakened.

In order to prevent the head from colliding with an edge of the opening during closing of the blade, in particular during an adjustment substantially out of the neutral position, it preferably has a shape tapering towards its free end.

Particularly preferred is a development of the band assembly according to the invention, in which the head comprises radial projections. As a result of this measure, undercut surfaces are formed on the head which, in the event of a tilting of the wing, act as a result of a violent attempt to break open with the edges of the openings and thus further make removal of the wing more difficult.

In order to improve the visual impression conveyed with a band arrangement according to the invention with the wing open, in a particularly preferred embodiment at least one closing element is provided, which releases the head as it enters the respective opening and closes it automatically when the head is displaced outwards. In addition to improving the mediated optical impression, this arrangement further reduces the risk of contaminants penetrating into the openings when the wing is open, which is of particular importance in particular for exterior doors.

The closing element can in principle be designed in any manner coupled to the movement of the wing. However, it is particularly preferred to equip the closing element with a flexible, attached to the frame or the wing, in the unloaded state each an opening overlapping tab, which is pushed aside by a penetrating head against a restoring force, since this embodiment is particularly simple and inexpensive to produce and mountable. The adjusting device may comprise an adjusting screw engaging in an undercut groove in the frame or wing mounting part. The latter has - particularly preferably - a flat cylindrical head, which engages in a cross-sectionally T-shaped groove which extends transversely to the adjustment direction, and a machine thread, which engages in a complementary, provided on the wing or the frame internal thread , When the adjusting screw is screwed in or out, the latter is entrained due to the positive connection between the adjusting screws and the respective fastening part until the desired position of the blade in the frame has been set. Experiments have shown that the self-locking of the adjusting screw achieved in such a band arrangement is sufficient to prevent an automatic turning of the adjusting screw, which would result in a misalignment of the wing in the frame.

Particularly preferred is a development of the invention Bandanord- tion, in which for each adjusting screw a self-tapping external thread comprehensive threaded bush is provided, which has a complementary to the machine thread of the adjusting screw internal thread. The band assembly is then particularly flexible with respect to the adjustment, since the threaded bushing in frames or wings of different materials and types - for example, solid wood, metal or plastic hollow profile - can be introduced.

In the drawing - schematically - a preferred embodiment of a band assembly according to the invention is shown. Show it:

Figure 1 is a perspective view of this band assembly in the assembled state at 180 ° open wing.

Figure 2 is the same view of this band assembly in an exploded view.

Fig. 3 is a view of this band assembly of Figure 1 from above with the wing closed. Figure 4 is the same view as in Figure 3, but after an adjustment for the purpose of adjusting the wing in the frame.

Fig. 5 shows a section along section line V-V in Fig. 1 by the adjusting device and

Fig. 6, the band assembly in a Fig. 4 corresponding view, but at about 20 ° open wing.

In the drawing as a whole with 100 designated band assembly for hinge-joint connection of a wing 1 to a frame 2, wherein only portions of the wing and the frame profile 3, 4 are shown, comprising a frame fastening part 5 having frame hinge tabs 6 and a wing fastening part 7 comprehensive Wing hinge tabs 8. The frame and wing hinge tabs 7, 8 are hingedly connected to one another by means of a hinge pin 11, which passes through the hinge parts 9, 10 and is not shown in detail in the drawing.

In the embodiment of the band assembly shown in the drawing, the frame hinge tab 6 is screwed by means of two fastening screws 12 which pass through the frame attachment member 5 in holes 13, fixed to the frame profile 4. It is understood that instead of the fixed screwing alternatively or additionally an adjustable mounting of the frame hinge flap 6 may be provided in a manner as will be explained below using the example of attachment of the wing hinge flap 8 on the sash profile 3.

The adjustable in the wing plane - also horizontally adjustable - attachment of the wing hinge flap on the wing profile serve two guide members 14, each having a threaded extension 15, a subsequent to the threaded extension 15 cylindrical guide portion 16, a subsequent projecting radial projection 17 and a have head 18 tapering towards its free end. The length of the cylindrical guide portion 16 is made larger than the thickness of the blade fixing part 7, so that the wing hinge tab on the guide portion in the displacement direction V in Fig. 3 is displaceable, wherein the maximum adjustment is limited on the one hand by the radial projection 17, on the other hand by the mounting surface 19 of the airfoil 3. As can be seen in particular from FIGS. 3, 4 and 6, the frame profile 4 comprises for each guide member 14 a threaded bore 20, which is designed to be complementary to the threaded extension 15.

The displacement of the wing attachment part 7 relative to the mounting surface 19 is an adjusting device 21 shown in Fig. 5 It essentially comprises a threaded bushing 22 which has a self-tapping external thread 23 and is screwed into a bore 24 in the airfoil 3, so that their outer, in Fig. 5 above end face 25 terminates approximately with the mounting surface 19. From this front end face 25, over a part of its length, a threaded bore 27 having a machine internal thread 26 is incorporated into the threaded bushing 22, the lower end of which passes into an internal hexagon 28 for engagement of a rotary tooling for screwing the threaded bushing 22 into the bore 24.

In the threaded bore 27 a complementary external thread 29 having adjusting screw 30 is screwed over part of the length of its external thread 29. The outer end of the adjusting screw 30, shown in the drawing above, forms a flat-cylindrical head 31, which engages behind the undercut surfaces formed by a T-shaped groove 32, so that by screwing the adjusting screw 30 in and out, the wing fastening part 7 and thus the wing hinge flap 8 can be displaced perpendicular to the mounting surface 19.

In order to initiate the rotary actuation, an internal hexagon 33 is machined from the head 31 of the adjusting screw 30, with which a rotary tool, which is guided through a bore 34 (see Fig. 1) and not shown in the drawing, can be brought into engagement.

As can be seen in FIGS. 3 to 6, radial protrusions 35 are provided on the head 18 of each guide member 14 and are not shown in FIGS. 1 and 2 for the sake of clarity. The radial projections 35 lead to a hooking of the head 18 in an opening provided in the frame profile 4 opening 36, in which the head 18th the respective associated guide member 14 penetrates when the wing is tilted in an attempt to violently open in the frame.

Referring particularly to FIGS. 1 and 2, the guide members 14 and the associated openings 36 are arranged such that the latter does not extend through the frame attachment portion 5, thereby avoiding material weakening thereof.

Between the frame fastening part 5 and the facing side of the frame profile 4, a closing element 37 is clamped, which is formed from a flexible, such as spring or rubber-elastic material. It comprises each of an opening 36 associated tabs 38 which at least substantially close the associated opening 36 with the wing open, but have an elasticity that they are pivoted by a penetrating head 18 of a guide member 14 when closing the wing, overcoming the elastic force.
