Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that the cloth shaft is provided in a cassette, the cassette being provided on its free vertical end face with a removal lid connected to the front free end of the hinged arm, the cassette being in an unrolled state. a device for adjusting the inclination angle of the hinge arm, a swing bearing for moving the hinge arm from a horizontal position in a stowed state to an inclined position in an extended state, and a releasable device for fixing the hinge arm in its inclined position. The present invention relates to a cassette type sunshade tilting hinge having a hinge arm and provided with a locking device.

In the case of this type of cassette sunshade, the fabric shaft and the sunshade are stored in a cassette that is closed on all sides. In this case, the vertical closure of the free end face of the cassette is formed by the removal lid. The removal lid is connected to the free end of the hinge arm and closes the cassette when the hinge arm is stowed. In order to achieve this complete closure, and to nevertheless be able to tilt the hinge arm of the sunshade horizontally during unrolling, the bearing of the hinge arm is fitted in the last phase of the oscillation. A rocking motion must be performed from an inclined position to a horizontal position. On the other hand, in the extended state, this rocking motion must be reliably prevented. As a result, the rolled-out sunshade is no longer affected by external forces, especially wind and vibrations around the swing wheel. For this purpose, known cassette sunshades use so-called wind damping devices of various constructions. This wind braking device essentially consists of a locking device. This locking device is engaged in the extended state,
Fix the hinge arm in its tilted position. Furthermore, in the case of a tilting hinge of a hinge arm type sunshade, it is necessary to be able to adjust the inclination angle in the extended state.

The problem on which the invention is based is therefore to provide a tilting hinge that is as simple as possible and therefore requires no maintenance and can be produced at low cost.

This tilting hinge should have adequate stability even under large forces and should allow reliable fixation, especially in the extended state. In this case, it should be possible to easily adjust the inclination from the front in each position.

This problem is solved according to the present invention, in which a locking rocking body is provided on a rocking bearing so as to be swingable around a rocking axis, and a bearing stand is supported on the locking rocking body so as to be rockable around a rocking axis. the bearing pedestal has a hole, the adjusting bolt passes through the hole perpendicularly to the second oscillating axis, and the inner end of the adjusting bolt with an external thread comprises:
engaged with a threaded base having a screw hole, the threaded base being swingably supported about a third pivot axis above the first pivot axis and inward of the second pivot axis; On the locking rocker,
a locking bolt is guided parallel to the pivot axis of the bearing base and the pivot axis of the threaded base, and the locking pin is movable towards and together with the abutment shoulder of each hinge arm; The free end of the locking pin extends towards the abutment shoulder, so that the locking pin slides in the final phase of the inward pivoting movement of the hinge arm and is formed between the locking pin and the adjusting bolt. The problem is resolved by releasing the locking device. By forming a locking device between the adjustment bolt for inclination adjustment and the lock rocking body that carries the hinge arm and is swingably supported, the adjustment bolt can be easily operated from the front at each position. Moreover, it can be operated even when the sunshade is only slightly extended. By means of a locking pin provided according to the invention, which can be actuated by the abutment shoulder of the hinge arm, the locking fixes the inclination in the extended state in a precisely definable phase of the inward swiveling movement. Disassembly of the device is possible. This allows the locking device to be released if necessary in order to insert the removal lid into the cassette, and in the case of movement in the opposite direction the locking takes place immediately when the removal lid leaves the cassette.

Claim 2 shows a structure of the locking device which is extremely simple and easy to manufacture. The adjustment bolt provided according to claim 3 allows precise fixing. The abutment shoulder operates the locking pin no matter what angle of oscillation the hinge arm is in. That is, the tilting hinge of the invention can be easily adapted to a given geometry, in particular to existing cassette dimensions. Claim 4.5 indicates the possibility of achieving a harmonic movement between the locking pin and the shade arm.

According to claim 6, it is advantageous if the locking pin is biased by a spring in the locking direction.

Other features, advantages and details of the invention emerge from the following description of a preferred embodiment, based on the figures.

The tilting hinge 1 shown in the figure is fixedly connected via a carrier 2 to a cassette 3 forming a closed housing. The cassette can be fixed to the external wall 5 of the building via a latching device.

A cloth shaft 6 is provided within the cassette 3 and is rotatably supported around a shaft 7. A sunshade cloth 8 is wrapped around the cloth shaft. The front end of the shade cloth 8 is provided with an edge strip 9. The edge strip engages the edge strip 10 of the removal Mll. The removal lid 11 covers the vertical free end surface of the cassette 3 in the stored state.

In this case, the molded projections 12, 13, 14 provide a sealing closure.

The removal lid 11 is connected to the 11+7 free end of the hinge arm 15 via a schematically illustrated pivot hinge 16 with a vertical pivot axis 17 . Hinge arm 1
The inner hinge arm portion of 5 is connected via a swing bearing 19 to a tilting hinge l that is tiltable about a swing axis 18 .

The tilting hinge l has a locking rocker 20. This locking rocker has a generally rectangular body 21 surrounding a central recess 22. Arms 23 are formed protruding from both narrow width surfaces of the main body 21. These arms each have a swiveling bearing 2 about a first swiveling axis 81 relative to the holding member 25 of the carrier 2.
4 can be swung.

The carrier 2 and the holding element 25 are shown schematically in the figure and can themselves be constructed in any desired manner.

A bearing stand 2G is provided within the recess 22. This bearing stand 26 is supported by the main body 21 of the locking oscillating body 20 via a bearing pin 27 so as to be able to swing around the second oscillating axis Sl. The bearing pedestal 26 has a hole 27'.

An adjustment bolt 28 is engaged with this hole. The adjusting bolt 28 has on its outer surface a head 29 with a hexagonal hole 3a for inserting a cap screw key. The end of the adjustment bolt opposite the head 29 is reduced in size and has an external thread 31. 1 and 2 show the screwed-in state of the adjustment bolt.

The male screw 3I is engaged with a screw hole 32 of a threaded base 33. The threaded base 33 is mounted above the oscillating axis S by bolts 34, 35 which act as oscillating bearings.
It is supported on the carrier 2 so as to be able to swing around 3.

By operating the adjustment bolt 28, the inclination of the hinge arm 15 in the extended state is changed. In this case, the inclination can be easily adjusted from the front in all positions of use.

The adjusting bolt 28 is provided in its head part 36 with an external recess 37 in the form of an annular groove. In the area of this recess 37, a locking pin 40 is mounted in a guide 39 so as to be longitudinally movable in a direction perpendicular to the axis 41 of the adjusting bolt 28. This guide has a cylindrical hole 38.

One end 42 of the locking pin 40 is biased by a coil spring 43. A coil spring is mounted within the hole 38 and supported on the end wall 44 of the hole. The adjusting bolt 45 passes through the coil spring 43 and its head 46 overlies the hole 38 and its inner end engages in the threaded hole 47 of the locking pin 40. Therefore, by operating the adjustment bolt 45 using the head 46, the position of the locking pin 40 within the hole 38 can be adjusted. The locking bottle 40 also has an outer recess 48 in the form of an annular groove. The diameter d+ of the adjustment bolt 28 in the range of the side recess 37 and the diameter d+ of the locking pin 4G in the range of the fourth part 4B, or the longitudinal axis 1a4 of the adjustment bolt 28
1 and the longitudinal axis 49 of the locking pin 40 is determined as follows. That is, when the four parts 48 overlap the longitudinal axis 41 of the adjustment bolt 28? This, locking pin 4
0 is free to move in the direction of the longitudinal axis 41 of the adjusting bolt 28 and the body of the locking pin 40 passes through the recess 37 of the adjusting bolt 28, thereby creating a locking action, i.e., the locking pin 40 The member connected thereto is the longitudinal axis 41
It is set so that it does not move in any direction.

The free end 50 of the locking pin 40 is biased by the force of the coil spring 43 and comes into contact with the abutment shoulder 51 in the angular range α immediately after the start of drawing out or just before the end of the storage.

Outside this range, the end 50 and the abutment shoulder 51 do not come into contact.

The operating mode of the tilting hinge of the present invention will be explained based on FIG. 2.

The axis 5 of the hinge arm 15 when the sunshade is in the retracted state.

As the angle α increases, that is, as the hinge arm 15 advances, the locking pin 40 is moved by the coil spring 43.
2, the hinge arm 15 is pushed upwardly toward the abutting shoulder 5I of the hinge arm 15 in FIG. Thereby, after the predetermined angle is reached, the recess 48 of the locking pin 40 is inserted into the adjustment bolt 28.
reaches outside the range of the longitudinal axis 41 of the f1 tablet bottle 4
The small diameter outer circumferential surface of 0 engages with a recess 37 of the adjustment bolt 28 formed by an annular groove. This is because a locking action occurs after the extended state has progressed, that is, the locking pin 4
This means that the body of 0 acts in conjunction with the recess 37 as a locking device. As the hinge arm 15 continues to extend, the abutment shoulder 51 disengages the end 50 of the locking pin. However, the locking pin remains in its locked position due to the action of the coil spring 43 (see upper part of FIG. 2).

When retracting the awning, the process in reverse is repeated. As can be seen in particular from FIG. 2, the inclination setting can be easily effected from the front via the adjusting bolt 28, independently of the operating mode of the tilting hinge. The adjustment bolt 45 is

settings.

From the above description, it can be seen that the structure of the invention ensures that in the extended state forces generated, for example by gusts of wind, are counteracted and that the removal lid can be connected to the cassette without problems in the beginning or end phase of the extending or retracting movement. It turns out that it can be done.
