Description

The invention relates to a band for pivotally connecting a wing with a frame and in particular a door leaf with a door frame having at least one band part.

A disadvantage of such known bands is that they often do not provide a desirable high security against burglary or are expensive to manufacture or assembly or increase the burglary security affects the visual appearance of the band. In particular, the resistance of many known tapes against Durchtrennversuche a band part, for example with a hacksaw, is often not satisfactory.

The invention has set itself the task of creating a band which is improved in terms of at least one of the disadvantages mentioned.

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

The band according to the invention serves for the pivotable connection of a wing with a frame, in particular the pivotable connection of a door leaf with a door frame. It has at least one band part. Preferably, two hinge parts, namely a wing hinge part and a frame hinge part are provided. The Band preferably also includes a hinge pin, with which the two band parts are pivotally connected to each other. In the context of this document, the term "band part" therefore refers in particular to the leaf hinge part and / or the frame band part. The band part preferably comprises a band reel area in which the band bolt is mounted or fixed on the band part and more preferably a band area, by means of which the band part can be fixed to a wing or frame.

To increase the security against burglary, an insert is provided in the at least one band part. It can therefore be provided in the embodiment with two band parts in both band parts or only in one of the band parts an insert. This insert preferably acts only when the band part was cut through to the use. Damage to the band part up to the use is therefore accepted. Surprisingly, it has been found that even such a damaged band part still provides sufficient resistance to burglary or attempted break-up. In other words, the insert may be an accessory.

Preferably, the insert is harder than the rest of the band part. As a result, he offers for example Durchsägeversuchen increased resistance.

If the insert, as in an important embodiment, has a degree of freedom about its own axis, then the use of a penetration test can counteract particularly effective. Because it can be achieved that the use in a Durchtrennversuch, such as in a Durchsägeversuch "rotates", whereby a severance of the insert is avoided or very difficult.

Advantageously, the insert is rotationally symmetrical, so it is preferably a rotation body, in particular a cylinder or a cylindrical pin.

Advantageously, the band part has a bore, preferably an axial bore, and the insert is further preferably arranged in this bore. When drilling is preferably a blind hole.

If the insert has play in the band part or the band part bore, in particular a clearance fit, then the degree of freedom of the insert about its own axis can be produced particularly advantageously and easily.

Advantageously, the insert in the band part, or the band part bore, is arranged so as to be easily rotatable, preferably around its axis of rotation.

Arrangements are preferably made so that the friction of the insert is low upon rotation in the band member. In this way, co-rotation, driven by the cutting tool, as little resistance as possible. The friction reducing provisions may be the selection of a suitable fit (clearance fit) between the insert and the bore in the strap member, as well as lubrication of the insert.

If a securing element for - preferably axial - securing the insert is provided in the band part, then a removal of the insert from the band part and thus repeal the increase in burglary is difficult. In addition, it prevents that the insert is lost, which facilitates the handling of the hinge part during storage and assembly.

Advantageously, the securing element comprises a press-fit element, or is formed by a press-fit element. The press-fit element is preferably arranged in the same hinge part bore as the insert. In a conceivable embodiment in which the bore extends through the entire band part (throughbore), two securing elements or press-fit elements are preferably provided. In the preferred embodiment, in which the band-part bore is a blind hole, it is preferred to provide exactly one securing element or press-fit element. The Presspassungselement forms an interference fit with the bore, so in any case (tolerance distribution) larger than the bore.

Advantageously, the securing element comprises a ball or is formed by a ball. The securing element or the ball is preferably arranged in the same bore as the insert, particularly preferably with an interference fit. The spherical shape has the advantage that the securing element is easy to press in and hard to bring out, since a ball no attack surfaces, for example, offers a pair of pliers or the like.

The invention also relates to a band member having the above-mentioned features. It also relates to a door with a door leaf and a frame in which the wing is attached to the frame with a band according to the above-mentioned features.

The band according to the invention, not shown as a whole serves to attach a door leaf to a door frame. It is accessible from outside with the sash closed. The tape is therefore safety relevant to burglary attempts.

The band has two band parts, namely a wing band part and a frame band part. The band part 1 shown in the figures may be the frame band part or the wing hinge part act. The two band parts are pivotally connected to each other by means of a hinge pin, also not shown. The belt part 1 shown has a belt reel area 6 and a flap area 7. In the tape reel region 6, the hinge pin, not shown, is mounted or fixed, and by means of the flap region 7, the hinge part 1 can be fastened to the door leaf or door frame. In this case, the attachment side 4 of the flap area 7 comes into contact with the wing or the frame in some areas. The flap area 7 has fastening bores 8, 8 ', which can be penetrated by fastening means, such as screws.

The band part 1 has a Sägesicherung. To increase the security against burglary, in particular to increase the resistance to sagging, an insert 2 is arranged in the hinge part 1.

The band part 1 has for this purpose a blind hole 3, in which the insert 2 is arranged. The blind hole 3 is arranged obliquely in the band part. The bore 3 and the insert 2 extend from the mounting side 4 of the strap part 1, which is not or hardly accessible in the mounted state of the strap part 1, to near the opposite side 5 of the strap part.

The bore 3 and the insert 2 extend through a connecting region 9 of the hinge part 1, which adjoins the belt roll region 6. In the exemplary embodiment shown, this connecting region 9 has a smaller thickness than the rest of the flap region 7, and is therefore particularly critical, inter alia for this reason, with regard to a severance test ( Fig. 2 ). The insert 2 extends through the entire region 9 and protects it reliably in this way.

The bore 3 and the insert 2 have a circular cross-section. The insert 2 is formed as a rotational body, namely as a cylindrical pin. The circular cross-section of the insert 2 has a diameter which is slightly smaller than the diameter of the bore 3. The insert 2 thus has radial play in the bore 3. The insert 2 can only be inserted or inserted into the blind hole 3. Anyway, he also has axial play. He can rotate freely about its axis of rotation A. The insert 2 points with others Words on a degree of freedom about its own axis A. A Durchtrennversuch, such as with a hacksaw, makes the band part 1 itself often no very much resistance. However, as soon as the saw blade has reached the insert 2, it rotates, driven by the saw blade. There is therefore no or only a very small relative movement between the saw blade and the insert. The saw blade therefore can not penetrate into the insert 2. The area of the band part 1 which has not yet been severed at this stage still forms a secure connection of the band roller area 6 with the area of the band area 7 ensuring the connection to the wing or frame.

The insert 2 may be made of a harder material, as the band part 1, such as hardened steel or hard metal. The axis of rotation A of the insert 2 is congruent with the axis F of the hole. 3

The blind hole 3 opens on the not in the assembled state of the hinge part 1 or difficult to access mounting side 4 of the hinge part 1. It is thus arranged so that the insert 2 can be achieved with the mounted band at best difficult. For these reasons, pulling out the insert 2 is difficult or prevented in a break-in attempt. The blind hole 3 may also be arranged such that, taking into account the length of the insert 2 in the axial extension of the bore 3 in the direction of the open side of the bore 3 no space to extract the insert by there further elements such as door or frame "are in the way".

To (further) increase the security against pulling out of the insert and to simplify the storage and installation of the band member may be disposed behind the insert 2, a securing element in the bore 3 (not shown). This can be formed as a press-fit element, more precisely as a ball. In the production of the tape, the insert 2 can then be introduced with clearance into the bore 3 and then the ball can be pressed behind this insert 2 in the bore 3. The ball is pressed in this embodiment only so far that the insert 2 also has some axial play and no interference affecting its rotation takes place clamping. The insert 2 is then captively arranged by the securing element in the band part 1 and the band part Can be handled like a hinge without use during storage and assembly.

The band part with insert may, at least in terms of its external dimensions, be shaped substantially like a conventional band part. Therefore, the band member can be mounted like a conventional band member and retrofitted into existing bands. Also it can be used in existing bands only in their burglar-resistant design.

The visual appearance of the tape is not affected by the increase in burglary security. The band is, at least in the assembled state, not visible from the outside, whether it has a band part with insert or a conventional band part, which can represent a security gain.

Among other things, since only the band portion may be modified on the band, the overhead to existing bands may be relatively low.
