The first section incorporates a thickened zone (28) with an embedded supplementary screw fixture (30).

Description

The present invention relates to a roller belt for doors, windows and the like, having the features of the preamble of claim 1.

Such example from the US Pat. No. 6,430,876 B1 Known roll bands have a frame band fastened to a fixed frame, a wing band attachable to a wing frame. The frame band comprises at least a first axle receptacle and the wing band at least one bearing eye, in which a bolt for mutually pivotal connection can be introduced. To fasten the frame band, a hinge tab is integrally formed on the first axle receptacle whose one leg, which is matched to the contour of the frame, usually extends into the rebate space defined by the frame and sash frame. The leg has at least one fastening device for attaching the roller belt to the frame.

Due to a design-related large distance between the Falzraumseitigen attachment and the axle can occur in the region of the leg during pivoting of the wing, especially in doors with an electric door opener, large forces.

These forces can cause a lifting of the frame strip from the frame, whereby the frame band can be loaded so much that the hinge flap can be damaged in the region of the fastening device. As a result, damaged frame strips have, for example, plastic deformations of the hinge strap or even break points in the region of the fastening device.

To improve a power transmission from the axle in the frame reveals the DE 200 05 202 a band assembly having a substantially strip-shaped hinge flap in which, in addition, near a front wall of the fixed frame, a fastening means for connecting the hinge strap is provided with a fold-side wall of the frame.

By introducing the fastener in the hinge strap this is naturally weakened. Moreover, this connection technique can only be used for special profiles, such as e.g. Aluminum frames are used. In addition, a subsequent vertical adjustment of the frame band is no longer possible. Furthermore, a lever between the axle and the additional attachment means is only shortened.

The invention is therefore an object of the invention to provide a roller belt of the type mentioned that reliably prevented by technically simple means lifting the tape.

This object is achieved in a roller belt of the type mentioned in the present invention, that the frame band at least in the region between the first axle and the front wall of the fixed frame, having extending band reinforcement with securing means, which securing means comprises at least one fastening means and at least one first recess, at the edge of which the fastener connectable to the frame is supported, and which first recess is designed as a groove or slot, so to dimension is that this, a vertical adjustment of the roller belt by - on the roller belt (10) integrated height adjustment (52) is not limited.

In this case, the band reinforcement extends at least between the first axle receptacle and the front wall of the stationary frame. The securing device preferably runs parallel to or congruent with an imaginary connecting line which runs perpendicular to the front wall of the window frame and through the center of the axle receptacle. In a design-related predetermined distance of the first axle from the frame so the effective lever can be reduced to a minimum. In order to transmit the opposite on opening or closing of the casement, acting on the axle receiving torque, the roller belt is designed such that the securing device comprises at least one fastening means and at least a first recess, at the edge of the fastening means is supported. For this purpose, for example, the recess may be an opening with a suitable contour, such as a countersink, in which a part of a nail or bolt engages positively. Furthermore, it is provided in the roller belt, that the first recess and / or possibly the second recess is a slot. The roller belt can thereby be readjusted within certain limits even after mounting the safety device. Further, the roller belt is designed such that the first recess and / or possibly the second recess is formed in the form of a groove. Preferably, this groove extends approximately axially parallel to the bar or hinge strap. The groove is preferably open in the axial direction to the outside, so that through the opening attached to the frame attachment means can be inserted into the groove. In particular, for balancing the level between sash and fixed frame, the roller belt is designed such that it has a height adjustment. This height adjustment device may be any embodiment known in the art. Preferably, however, the height adjustment device is integrated in the frame band. The recess, the groove and / or the slot are to be dimensioned so that they can not limit the vertical adjustment by the height adjustment.

The roller belt can be developed such that the band reinforcement has at least one length of the bearing eye sweeping bar.

A strip-shaped embodiment of the band reinforcement, which preferably extends over the entire length of the axle and the bearing eye and is made in one piece with the hinge tab, stabilizes the frame band in addition. A weakening of the hinge, e.g. through holes, for introducing the safety device can be largely avoided.

A particularly advantageous embodiment of the roller belt provides that the edge reinforcement in the assembled state at least partially rests flat against the frame.

As a result, the band reinforcement or the strip provide flat contact with the frame near the axle receptacle. The torques occurring during pivoting of the wing part can thereby be transferred over a large area in the form of a uniform pressure load on the frame.

To create further connections between the frame and the axle, the roller belt is advantageously formed so that a second recess is arranged in the axial direction below or above the first recess.

By a targeted distribution of as many contact points between the axle and the frame, in particular a weakening of the latter can be reduced. An impressions of the frame by transferring restoring forces on the minimally weakened by the additionally introduced security elements frame is almost impossible.

Such a roll band according to the invention can advantageously be further developed such that the groove has a dovetail-shaped cross-section.

Fastening means with a countersunk head-like stop can thereby be supported almost completely on the envelope of the groove.

The roller belt can be configured such that the fastening means has a stop which comes into positive contact with the first recess.

Of course, the fastening means may also have any other geometric shapes for the stop. Such a stop, for example, have a round or hexagonal cross section, which extends as large as possible across the imaginary connecting line between the frame and axle.

A particular embodiment of the roller belt provides that the fastening means in addition with a head end Has at least one device which projects into the axle and into which a securing element engages.

The stop and the head end of the fastener may be listed in one piece, for example. By projecting the head end into the axle receptacle, an additional contact point for supporting the bolt can be created. Likewise, the head end projecting into the axle receptacle can serve as a band and / or bolt securing in order to design the roll band as burglar-resistant.

Advantageously, the roller belt is constructed such that the fastening means is a screw.

Such a fastener can be efficiently inserted into the frame and is relatively quickly replace, for example, if instead of a lightweight sash made of plastic, a fire door made of metal should be used.

In order to effect a connection of the roller belt with the frame easily and quickly, the roller belt can be designed such that the securing element can be introduced via the axle.

The securing element may for example be a lock nut, which is screwed via the axle to a previously introduced in the frame grub screw.

Advantageously, the roller belt is designed so that the securing element is an eccentric connection fitting. This connection fitting can be similar to a related furniture connector in the form of a round nut introduced into the axle and in connection with the projecting into the axle receiving head of the fuse element, similar to the screw-in for furniture, engage in the device.

The device may for example be a longitudinally extending to the securing element constriction. By means of a tool to be introduced into the connector, the eccentric connector can be adjusted so that it is displaced to latch it in the direction of the frame after engaging the Sicherungselemtens.

The roller belt according to the invention can be designed both as a two-part or three-piece roller belt. For this purpose, advantageously, the roller belt is designed such that the roller belt has a second axle receiving. The band reinforcement then naturally extends in the area between the second axle receptacle and the front wall of the frame. Of course, this also applies to the bar and / or recesses or the groove.

Advantageously, the roller belt is designed so that it is made of metal, plastic or a combination thereof. As a result, different materials can be used to save costs or weight on the one hand and increased mechanical load capacity of individual components of the roller belt on the other hand. Depending on the material used then can also be used for mass production suitable processing and processing machines.
