Description

The invention relates to a hinge tab of a band for connecting a sash to a frame in a hinged manner about a hinge axis, with at least one mounting part that can be attached to the sash or to the frame, and with at least one hinge part that can be mounted on the mounting part. The invention also relates to a band which comprises such a band flap.

A band with such a band flap is from the WO 2007/028497 A1 known. The hinge parts and/or the mounting parts are designed in such a way that the hinge parts can be fastened to the mounting parts in different positions, so that the vertical distance of the hinge axis from the mounting parts can be changed. In this way, it is possible to adjust the sash perpendicular to the hinge axis, also referred to as “horizontal adjustment”. The disadvantage, however, is that an adjustment parallel to the hinge axis, also called "vertical adjustment", cannot be achieved with the hinge tab of this hinge.

From the publications DE 20 2012 104 137 U1 and WO 2008/003 372 A1 Band tabs of a band for the hinged connection of a sash to a frame are known according to the preamble of claim 1.

The invention is therefore based on the object of creating a hinge tab which is suitable for adjusting a sash in a frame in a direction parallel to the hinge axis and which enables improved mountability of a band comprising the hinge tab and a simplified hanging of a sash.

This object is achieved by a band flap with the features of claim 1 and by a band with the features of claim 7.

In the hinge tab according to the invention, one of the mounting part and the hinge part, in other words: either the mounting part or the hinge part, comprises an undercut groove with a longitudinal axis and a threaded hole that defines an axis of rotation, the longitudinal axis and the axis of rotation extending parallel to the hinge axis. There is an adjustment spindle screwed into the threaded hole with a front end designed as a support surface. In addition, the other of the mounting part and the hinge part, which does not have the undercut groove and the threaded hole, includes a projection engaging in the groove and a contact surface against which the support surface of the threaded spindle can be brought into contact. Due to these features, when the band tab is joined together, the support surface of the adjusting spindle lies against the contact surface. For a vertical adjustment of the sash in the frame, it is only necessary to move the threaded spindle in the direction of the axis of rotation using a rotary actuation, as this moves the hinge part parallel to the hinge axis. In addition to the particularly simple, vertical adjustability of the sash in the frame, the hinge tab according to the invention also offers the advantage that the hinge part can be attached to the mounting part by a simple displacement in the direction of the hinge axis, in that the projection is inserted into the groove in the direction of the longitudinal axis . The cost of joining the band part according to the invention and a band equipped with it is therefore low.

Particularly preferred is a variant of the invention in which the groove is provided in the mounting part and the projection on the hinge part. In this way, the distance between the axis of rotation of the threaded spindle and the hinge axis is maximized without increasing manufacturing or manufacturing costs Assembly effort would be involved. Maximizing the distance between the axis of rotation and the hinge axis is desirable, as this improves the accessibility of the threaded spindle, for example for the purpose of rotary operation.

Particularly preferably, the threaded hole is incorporated into the groove and extends from one end of the groove over at least part of its length. The internal thread of the threaded hole therefore does not extend over a full circle, but only over one or more circular arcs in which the cross section of the threaded hole does not lie within the cross section of the undercut groove. It has surprisingly been shown that the threaded spindle in such a hole regularly finds a sufficiently stable hold despite the lack of thread circumferential areas in order to be able to transfer holding forces introduced into the fastening part via the threaded spindle to the frame without causing damage.

Particularly preferred is a design of the hinge flap in which the contact surface of the hinge part is formed by a surface of the projection that extends transversely to the longitudinal axis. This preferred embodiment is characterized by a particularly low manufacturing effort.

The threaded spindle is - particularly preferably - designed as a stud screw. It preferably has means for attaching a turning tool, in particular an internal polygon or internal polygon, for example an internal hexagon or internal hexalobular or an internal twelve-edge or internal twelve-round. In the case of limited space, the design as an internal twelve-point or internal twelve-round is particularly preferred, since a corresponding turning tool can then be brought into engagement with the stud screw at an angular offset of 30 ° about the axis of rotation.

The hinge tab according to the invention comprises two mounting parts spaced apart from one another in the direction of the hinge axis and accordingly two hinge parts spaced apart from one another in the direction of the hinge axis. It is therefore a (at least) three-part band, in which another band flap with a further hinge part is provided, which engages in the distance formed between the two hinge parts and preferably at least almost completely bridges this. In this three-part hinge, the hinge flap with the two hinge parts is usually the frame hinge flap and the other hinge flap is the wing hinge flap.

According to the invention, the hinge parts include a receptacle for a hinge bolt defining the hinge axis. In the simplest case, the hinge bolt is a cylindrical rod, which can be inserted and fixed in the direction of the hinge axis through the receptacles, which in the simplest case have a circular cross-section. The ability to assemble a band comprising a band tab according to the invention and also hanging a wing can be made considerably easier according to the invention in that the band bolt is designed to be divided into two longitudinal sections with ends facing one another in a plane running transversely to the hinge axis and the ends facing one another are in positive engagement when the band has been put together or the sash has been hung. If the hinge tab according to the invention is one of a three-part hinge, a sash can be hung in a simple manner by first attaching the lower of the two hinge parts to a mounting part and inserting one part of the two-part hinge bolt into the corresponding receptacle of the hinge part and is determined. The further hinge part bridging the distance between the two hinge parts can then be pushed onto an area of the lower section of the hinge bolt that protrudes from the lower hinge part, after which a wing attached to this further hinge part is first hooked in and thus positioned. The further, here upper section of the hinge bolt can then be inserted into the receptacle of the further hinge part and finally the upper hinge part can be mounted by sliding it onto the hinge bolt, bringing the extension and the undercut groove into engagement.

When the sash is hung, the support surface of the threaded spindle is supported on the contact surface of the projection. If the band having the band tab according to the invention is a three-part band, and the band tab according to the invention is attached to the frame and thus forms the frame band tab, at least the lower mounting part or the lower hinge part includes a threaded hole for the adjustment spindle, which extends from the lower end into the groove. In this embodiment, an adjustment of the wing in the vertical direction is possible in that the adjustment spindle, which is pressed with its support surface against the contact surface due to the weight of the wing, is turned further into the threaded hole or turned further out of it. If - as preferred - a corresponding threaded hole is also provided in the upper mounting part or the upper hinge part, the hinge tab according to the invention can be used for both right- and left-hinged sashes.

In a preferred embodiment of the hinge flap according to the invention, the mounting part has at least one fastening hole running transversely to the hinge axis for a fastening means, for example a fastening screw, an expansion dowel, a dowel pin, etc., for fastening to a wing or to a frame.

The exemplary embodiment of a band flap according to the invention shown in the drawing and designated as a whole by 100 (hereinafter referred to as “band flap 100”) is designed as a two-part band flap of a three-part band. The hinge tab is equally suitable for attachment to a frame or a sash; In practice, however, it is regularly mounted on the frame and is therefore also referred to as a “frame hinge part”.

The band tab 100 is part of a band for the hinged connection about a hinge axis S of a wing, not shown in the drawing, to a frame, also not shown in the drawing. The hinge tab 100 comprises a lower mounting part 1 and an upper mounting part 2. The mounting parts 1, 2 can be attached to a frame with fastening means 3, which in the illustrated embodiment include self-drilling screws 4 and dowel pins 5, in the direction of the hinge axis S by a distance A be attached.

The assembly parts 1, 2 each serve to assemble a hinge part 6, 7. Each of the hinge parts 6, 7 includes a hinge bolt receptacle 8, 9 which extends in the direction of the hinge axis S and which serves to receive a hinge bolt 10 defining the hinge axis S.

The hinge bolt 10 is divided into two longitudinal sections 11, 12 with mutually facing ends 13, 14 in a plane E running transversely to the hinge axis S. The mutually facing ends 13, 14 are in a form-fitting engagement, for which purpose the end 14 of the upper longitudinal section 11 in the drawing is designed as an external polygon, the end 13 of the lower section 12 in the drawing is designed as a complementary internal polygon.

In the in the Fig. 1 and 2 In the assembled state of the hinge parts 6, 7 shown, they have a distance B in the direction of the hinge axis S. In practice, this is bridged by a hinge part, not shown in the drawing, of a hinge tab which is rotatably mounted on the hinge bolt 10 about the hinge axis S and which is regularly provided for attachment to a wing and thus forms a wing hinge flap.

As in Fig. 3 to 5 , which is one of the assembly parts 1, 2, namely the in Fig. 1 and 2 As can be seen from the mounting part 1 shown below in various views, the mounting part 1 comprises an undercut groove 15 with a longitudinal axis L which extends parallel to the hinge axis S. The groove 15 is approximately C-shaped in cross section and has a groove opening 16 extending over the entire length of the mounting part 1.

A threaded hole 18 is machined into the groove 15 from the lower end 17 of the groove 15. It defines an axis of rotation D, which runs parallel to the longitudinal axis L and therefore also parallel to the hinge axis S. The threaded hole 18 extends over a partial length T of the total length G of the groove 15.

As in Fig. 3 As can be seen, the internal thread 19 of the threaded bore 18 does not extend over a full circle, but only over three circular arcs 20, 20 ', 20", namely where the cross section of the threaded bore 18 does not lie within the cross section of the undercut groove 15.

The design of the hinge parts 6, 7 for the purpose of being able to be mounted on the mounting parts 1, 2 will now be discussed with reference to Figures 6 to 8 , which show the lower mounting part 1 and the lower hinge part 6, will be explained.

The lower hinge part 6 includes a projection 21 which extends over a part V of the total length W in the direction of the hinge axis S of the hinge part 6 (see Fig. 1 ). The projection 21 has an approximately T-shaped cross-section that is approximately complementary to the cross section of the undercut groove 15, so that the hinge part 6 can be displaced relative to the mounting part in the direction of the longitudinal axis L of the groove 15, but is mounted in a form-fitting manner on the mounting part 1 in other spatial directions is. The groove 15 and the projection 21 are adapted to one another in such a way that the hinge part 6 rests with contact surfaces 22, 22 'on counter-contact surfaces 23, 23' of the mounting part 1.

As in Fig. 1 can be seen, the upper end of the projection 21 is part of an upper end face 24 of the hinge part 6. Since the projection 21 only extends over a part V of the total length W of the hinge part 6, the end face 25 pointing away from the end face 24 jumps relative to the lower end face 26 of the hinge part 6 back. An adjusting spindle 27 screwed into the threaded hole 18 about the axis of rotation D engages in the free space created in this way. Its front end facing the end surface 25 is designed as a support surface 28, with which it rests against the end surface 25 in the assembled state, which thus forms a contact surface 29 for the support surface 28.

An assembly of a band formed with a band tab 100 according to the invention and a hinged fastening of a wing and its vertical adjustment can be carried out in a particularly simple manner. For this purpose, the lower mounting part 1 is first fastened, for example, to the frame by screwing in the screws 4, which extend through holes 30 in the mounting part 1 provided for this purpose. If the fastening was not already carried out with the adjusting spindle 27 screwed into the threaded hole 18, the adjusting spindle 27 is now screwed in. The projection 21 of the hinge part 6 is then adjusted accordingly Fig. 1 inserted from above into the undercut groove 15 and shifted downwards until the contact surface 29 rests on the support surface 28. If this has not already been done before, the lower longitudinal section 12 of the hinge bolt 10 is now inserted into the hinge bolt receptacle 8 and fixed. Since the longitudinal section 12 of the hinge bolt 10 protrudes beyond the upper end face 24 of the hinge part 6, a wing provided with a hinge tab (not shown in the drawing) can now be opened by pushing on a hinge part This band tab can be hung on the lower longitudinal section 12. A vertical adjustment of the sash can be carried out by rotating the adjusting spindle 27 about the axis of rotation D.

With the one in the Fig. 1 and 2 In the illustrated embodiment of a three-part band, an upper mounting part 2 and an upper hinge part 7 are also provided. The design of the mounting part 2 corresponds to the mounting part 1 described above, but is mounted rotated through 180° so that the threaded hole 18 is at the top. Accordingly, the upper hinge part 7 is also mounted on the mounting part 2 in the opposite direction. The hinge bolt receptacle 9 of the hinge part 7 stores the in Fig. 1 and 2 Longitudinal section 11 of the hinge bolt 10 shown above, the area of which protrudes downward from the hinge part 7 engages in the hinge part of the hinge tab, not shown in the drawing. The assembly of the hinge part 7 with the longitudinal section 11 can therefore be carried out in a simple manner by inserting the projection 21 of this hinge part into the groove 15 from above. The upper hinge part 7 then rests with its lower end face 31 on the hinge part, not shown in the drawing. The upper hinge part 7 can be assembled with the longitudinal section 11 of the hinge bolt 10 pre-assembled. It is also possible to first assemble the upper hinge part 7 and then insert the longitudinal section 11 from above through the hinge bolt receptacle 9.

An adjusting spindle 27 is not absolutely necessary on the assembly part 2 shown above. However, it can be provided to prevent the upper hinge part from being removed by moving it upwards without the need for further measures.

By providing a threaded hole 18 in the upper mounting part 2, a hinge tab according to the invention can be used for both left- and right-hinged sashes without any further changes.
