Description

The The invention relates to a shaft bearing assembly comprising a a shaft or a shaft drive coupled bearing element, and an awning.

at Awnings, in particular in round sleeve and cassette awnings, The fabric shaft is on both sides of the side covers of the awning housing attached. On a side cover is usually a pivot bearing provided in the form of a pivot pin. At the other side cover is often a crank mechanism or one in the fabric shaft attached electric motor attached.

The Torque is transmitted to the side covers. this applies also for the vibrations and noises when or extending the awning. The bearings of the Cloth shaft are usually arranged centrally in the awning housing and rigidly connected to the side covers. For larger ones Awning widths depends on the fabric wave. The awning cloth touches the inside of the case respectively the cassettes and scrubs at the seams. Furthermore wrinkles form when winding the awning fabric. The awning cloth is mostly rolled up on grooved tubes, resulting in a jerky Run of the towels. leads. The engine noise of the motor arranged in the roller shaft causes vibrations, that of the cassette or the housing as a resonator be strengthened.

From the DE 20 2005 018 707 U1 is an awning, in particular Gelenkarmwnise, comprising a rotatably arranged in a housing arranged canvas shaft for winding and unwinding of a cloth roll. The cloth wrap is free in the vertical direction on an approximately horizontal housing bottom. There is provided a vertical movement of the cloth shaft enabling coupling means between the drive and the cloth shaft.

task the present invention is to provide a shaft bearing assembly, with the one-pointed support of the cloth shaft in the awning box prevents and reduces the rolling noise of an awning become.

According to the invention This object is achieved by a shaft bearing arrangement of the type mentioned in a particularly simple and surprising way achieved in that the bearing element along as as Bolt trained vertical guide movably arranged is. Due to the weight of the canvas shaft, the bearing element moves along the bolt when the winding diameter of one on the fabric shaft wound up cloth roll when unwinding or when rolling up increases. This can ensure that the cloth wrap over its entire length always rests in the awning box. Thereby The friction is distributed to all seams, as the cloth shaft in the middle can not sag anymore. The awning cloth is further spared, that less wrinkling Tends when it's on a straight wave rather than a sagging one Wave is wound up. The bearing element is preferably on the Bolt out and thereby secured against rotation.

at a preferred embodiment may be provided that the bolt is at an angle of ± 15 ° to the vertical is arranged. According to the invention is also a Bolt with an orientation slightly different from one exactly vertical arrangement of the bolt deviates, as a vertical guide considered.

Especially preferred in this context, if the bolt in different Angle to the vertical is fixed. This may cause the inclination the bolt so that the awning cloth with as possible low effort can be loaded and unloaded and Nevertheless, a sagging of the fabric shaft is prevented.

at an advantageous embodiment, the bearing element as a disc, preferably made of plastic and / or a sound-damping material, be educated. Also, the sound-absorbing material can be formed of plastic. By this measure can the propagation of vibrations of the canvas shaft can be reduced. Particularly preferred is an embodiment of the bearing element made of elastic plastic with a Shore hardness in the range 75-98 shore, preferably in the range of about 80-95 Shore.

A very good guidance and reliable mounting on the bolt results when the bearing element has a passage opening for the bolt. As a result, the bearing element is on guided the bolt.

Further Benefits arise when between the bearing element and stops Damping means are arranged. By damping means are Noise is muffled and becomes a particular Propagation of vibrations up to the housing of an awning prevented. The damping means can make noise of the drive, especially a tubular motor. The damping means can be made of latex foam or cellular rubber, elastic be and have a high resilience. Preferred is a Shore hardness in the range of about 20-45 Shore, preferably 25-40 Shore, for the cushioning agent. The stops can be the vertical movement of Limit wave.

advantageously, are the damping means between the bearing element and braced the attacks. This means that the damping means compresses to be built in. Therefore, they can be jolting movements cushion the bearing element. The lower damping means becomes even stronger when unwinding the awning compressed while the upper damping means a bit relaxed. When winding the awning fabric, the bearing element moved vertically upward so that the upper damping means is compressed while the lower damping means relaxed.

at an advantageous embodiment may be provided that the Damping means as an elastic ring, which is the bearing element surrounds, are trained. Such designed bearing elements can be made Tailored pipes or plate material by means of water jet cutting be cut out.

at an embodiment may be provided that the bolt is arranged on a stud holder. On the stud holder can the stops may be formed, on which the damping means issue.

at An embodiment of the invention can be provided that the Stud holder as a U-shaped bracket or side cover an awning box is formed. At a U-shaped Bracket, the bolt can be attached very easily. In addition, the bracket can easily on a side panel an awning housing, for example a cassette, be attached.

If the stud holder in a predetermined angular range in different Angle positions can be locked, can via the stud holder the orientation of the bolt can be set and fixed.

In the scope of the invention also includes an awning, comprising a wound up on a rotatable fabric shaft and unwound Awning fabric and a shaft bearing assembly described above for Storage of the cloth shaft. Experiments have shown that a vertical guide the cloth shaft reduces the friction in the awning box. At the same time the necessary force when rolling in and out is reduced and become Noise minimized.

The Seams of the awning can be spared, if plain bearings are provided in the area of the awning seams are.

Especially it is preferred if the wound on the shaft cloth wraps lies in a half-shell-shaped edition. The edition can be part of an awning box. This prevents that the canvas shaft bends. In the half-shell-shaped Edition can additionally slide bearings in the area be provided the awning seams.
