Description

The invention relates to a support device for holding a gaze and / or sun protection in a position taken along a predetermined by a tension cable of the gaze and / or sun protection movement path of the support device. The invention further relates to a gaze and / or sun protection device with such a support device

A glare and / or sun protection is usually formed by a pleated blind or a blind or a curtain and attached to a window or door frame. In this case, by means of rope tensioning devices, at least two cables are preferably tensioned between two opposite edges of the window or door frame, which serve for holding and / or guiding the gaze and / or sunscreen. The gaze and / or sun protection, for example the pleated or the blind or the curtain, is also preferably held in shape by limiting rails on two opposite edges of the gaze and / or sun protection in the cable tension direction.

There is a requirement to be able to move such a view and / or sun protection along the tensioned ropes and to be able to hold it in an assumed position on the tensioned ropes, in order to enable a shifting of the gaze and / or sun protection along the tensioned ropes. This requirement exists in particular if the gaze and / or sun protection does not cover or cover the entire window or door surface. A shift may be necessary or desired, for example, due to a changing position of the sun.

In order to meet these requirements, support devices are known in the prior art, the mechanical locking mechanisms, for example based on detent or clamp connections, have to keep the gaze and / or sunscreen in a set position. However, these support devices have the disadvantage that the locking mechanisms are often very expensive to use, and then the locking mechanism for moving the support device also has to be solved under some effort again. This is very time consuming for a user or operator of the gaze and / or sunscreen. In addition, the production of such, usually complex locking mechanism due to the large number of individual components is relatively expensive.

Out US 2013/0233500 A1 a support device is known in which the tensioning cable is tensioned between three deflection rollers, two deflection rollers being arranged on the right side and a deflection roller being arranged on the left side of a movement path of the support device predetermined by the tensioning cable. This support device has the disadvantage that the view and / or sun protection is not reliably held in a position assumed, since the voltage exerted by the pulleys on the tension cable tension is relatively low.

It is therefore an object of the invention to provide a new support device, in particular a support device which allows a simple shifting of a gaze and / or sun protection in a designated position and then holds the gaze and / or sunscreen reliable in this position. It is also an object to provide a gaze and / or sun protection device with such a support device.

This object is achieved with regard to the support device by the features of claim 1 and with respect to the gaze and / or sun protection device by the features of claim 13. Advantageous embodiments and further developments are specified in the respective dependent claims.

The support device according to the invention comprises a support body for attaching the support device to a goggle and / or sunshade, preferably on the boundary rails of a gaze and / or sunscreen, wherein the rope is or is guided on or through the support body. Furthermore, the support device comprises at least three rotatable deflection rollers for deflecting the rope on or in the support body, wherein the at least three deflection rollers are arranged on or in the support body, wherein at least two first deflection rollers are arranged at a provided first distance to the movement path, and at least one second deflection roller in a provided second distance is provided for the movement path.

The rope is such guided or guided around the pulleys that it is stretched between two first pulleys and a second pulley or is stretched so that it is pressed against the pulleys or is and the gaze and / or sun protection by this voltage in a provided position is held or durable.

According to the invention, the second distance to the movement path is greater than the first distance to the movement path and the second deflection roller is arranged along the movement path of the support device between the two first deflection rollers on the same side of the movement path.

The advantages of the invention are, in particular, that with the aid of the support device according to the invention, a gaze and / or sunshade can be reliably held in a well-held position in a simple manner, without having to actuate locking mechanisms in any way or other further manipulations are necessary. This makes the device particularly easy to handle. Characterized in that the second distance of the second deflection roller to the movement path is greater than the first distance of the first deflection roller to the movement path, and by the associated arrangement of first and second pulleys on the same side of the movement path, a voltage of the tensioning cable is effected, the support means and so that the gaze and / or sun protection reliably holds in a occupied position.

The first distance, on the other hand, preferably remains unchanged, ie the reduction or enlargement of the second distance simultaneously leads to a corresponding reduction or enlargement of the distance between the at least two first deflection rollers and the at least one second deflection roller.

An advantage of this development, for example, is that due to the variability of the second distance by the suspension of the suspension section an excessively strong adjustment of the cable tension is corrected by a user, so that even then a movement of the gaze and / or sunscreen is possible. Another advantage, for example, is that a weakening in the course of time cable tension is also at least partially corrected by the suspension of the suspension section.

Another advantage, for example, also be that is compressed by the suspension during a movement of the support device along the intended movement path of the suspension portion such that the second distance and - at the same first distance - thus the distance between the at least two first pulleys and the at least one second deflection roller and thus the tension of the rope between the deflection rollers is reduced in size such that a displacement of the support device along the intended movement path is facilitated.

This aforementioned development comprising suspension section and variable second distance thus brings with it in particular the advantage that the support device, in addition to holding the gaze and / or sunshade in an assumed position, also permits easy shifting of the gaze and / or sunshade from one position or in a different position, because the tension of the rope is reduced by the suspension as a whole or at least during a movement of the support device along the rope. This function also brings the device only by their design and without the need for further manipulation or the use of tools with it.

According to one embodiment of the invention, each deflection roller is mounted on an axle, wherein the axes of the at least two first deflection rollers are arranged outside of the suspension section on or in the support body and the axis of the at least one second deflection roller is arranged within the suspension section or on the suspension section.

Furthermore, it can be provided that the suspension portion is designed as a bellows, wherein the bellows forms a plurality of collapsible folds, wherein the folds are formed perpendicular to the suspension path.
