Abstract

An awning including a canvas shaft, a canvas wounded onto the canvas shaft, and a sleeve enclosing the canvas shaft. A stationary support means carries the sleeve. An arrangement for adjusting an inclination of the sleeve by rotation contains one lateral sleeve carrier which is connected to a respective lateral holder and which can be rotated relative to the holder about the awning-canvas-shaft axis. An actuating element, which can be moved serves for adjusting the inclination of the sleeve.

Description

The invention relates to an awning, with a sleeve which surrounds a roller tube whose cloth is retractable and extendable through a slot-like opening in the sleeve, with a stationary support device for the sleeve, from the lateral holders of the sleeve is held, and with a Device for adjusting the inclination of the sleeve by turning it around the cloth shaft axis.

In such known awnings the fabric shaft is enveloped by a surrounding sleeve. This protects the cloth from external environmental influences when the awning is retracted.

Through the slot-shaped opening, the cloth is extended or retracted.

Often it is desirable not extend the cloth horizontally out of the sleeve, but usually inclined in the direction of gravity downwards, for example. With a tilt angle of 30 °, 40 °, 50 ° or more degrees, depending on the customer.

Since the slot-like opening in the sleeve should be kept as narrow as possible, the cloth would touch an edge of the slot opening. If the slit opening were, for example, oriented such that the cloth could move out of the slit without any contact when it moved horizontally, this would strike over the lower slit edge if the cloth had an incline. Furthermore, the drop bar could not be approached completely at the dropout of the cloth to the slot opening.

It is therefore provided to make the sleeve rotatable about the fabric shaft axis, so that the slot-like opening can be aligned according to the desired angle of inclination (cf .. EP 0 593 389 A).

In a known construction, this adjustability is accomplished such that axially projecting laterally from the sleeve two diametrically opposed studs, which are displaceable in corresponding circumferential slots extending through a certain circumferential angle in the lateral holder. In the desired rotational position then the studs are determined by over-tightening from the outside in the axial direction adjusting nuts by jamming.

The adjustment angle range up to about 55 °.

During assembly, the procedure is such that after mounting the awning these adjusting nuts are released and the sleeve is rotated according to the wishes of the customer in the desired Ausfahrneigung the cloth and then the adjusting nuts are tightened again.

A disadvantage of this locking principle is that in the long run, the sleeve can rotate relative to the holder. When the awnings are extended, considerable forces are involved in wind gusts which, despite vigorous tightening of the adjusting screws, can lead to an adjustment of the inclination. Especially with very wide and very extensible awnings, the extended cloth surface offers a significant attack surface.

Another disadvantage is that all components of an awning are usually coated with materials that have a very smooth surface. This is done not only because of the visual impression, but also so that the awning exposed to the environmental influences not dirty by adhesion of dirt on rough surfaces gradually unsightly. These smooth surfaces favor a twisting of the sleeve when beating through gusts of wind.

If the customer changes his or her desire to adjust the inclination, it is imperative to remove lateral end caps in order to provide the necessary manipulations in the axial direction.

If the awning extends over the entire width of a balcony protruding from a house wall, manipulations are thus to be carried out laterally beyond the balcony, which represents a danger for the handling person and therefore should not be carried out by the customer himself.

Solutions have been sought to the effect that the adjustment so that viewed from the radial direction accordingly directed manipulations are possible for adjustment.

But then appropriate mechanisms must be provided to implement these manipulations in rotational movements of the sleeve.

However, it is an aspiration in cassette and tube awnings to make them as slim as possible and less bulky, so get away from the bulky box awnings and ultimately create a structure that is essentially shaped by the outer contour of the slender sleeve, or in cassette awnings, from the contour of the cassette, which additionally covers the arms, this usually being done by the drop profile of the drop bar.

It is an object of the present invention to provide an awning with a device for adjusting the inclination of the sleeve, which allows a simple and permanent adjustment of the inclination, and which does not build bulky.

According to the invention the object is achieved in that the device each has a lateral sleeve carrier, which is in communication with the respective lateral holder and the Cloth shaft axis is rotatable relative to the holder, that in the sleeve carrier is provided in a tangential direction to an imaginary turning circle slot opening in which a sliding block runs, that in the direction of the slot opening rectilinear actuator is provided, which is supported on the one hand on the sleeve carrier and on the other hand, on the sliding block, and that the sliding block further extends into a radially extending to the fabric shaft axis slot opening in the stationary holder and is supported in this.

These measures now have many significant benefits.

An actuator which moves tangentially to an imaginary turning circle can be actuated by an operator standing in front of the awning, so that no manipulations extending laterally beyond the awning are necessary any more.

A sliding block, which moves along a tangent, has, depending on the displacement along the tangent, a more or less large distance from the center of this imaginary turning circle, that is a variable distance from the axis of rotation of the canvas shaft. This radial mobility is now given by the fact that in the stationary holder corresponding radially extending slot openings are provided, in which the sliding block is supported.

With this basic principle, it is now possible to allow by a rectilinear adjustment of the actuator rotation of the sleeve carrier relative to the stationary holder by the sliding block along the slot opening is moved in a straight line by the actuator. The implementation of this linear movement in a rotational movement of the sleeve is characterized in that the sliding block is supported on the stationary holder. The necessary radial mobility, so the change in the radial distance of the sliding block of the rotation axis is simultaneously made possible in that this opening is formed in the stationary holder as a radial slot opening. By interaction of these basic components an extremely compact adjusting device is created, which is easy to use and does not disturb the appearance of the slender awning. The actuator, which rests on the sliding block, at the same time blocks the sleeve carrier from further inclinations, so that even very heavy and wide-spreading awnings are securely held in the tilt position.

In a further embodiment of the invention, it is provided to form two opposing such devices with respect to the fabric shaft axis, whose sliding blocks are in opposite directions.

This measure has the advantage that in addition to the inclination adjustment at the same time by the same components a high-impact protection can be accomplished.

The displaceable in the tangential slot opening sliding block is acted upon and adjusted from one side by the actuator. This means that it could move away from the actuator in the opposite direction, for example when it is pushed upward when the cloth is extended. In other words, the actuator rests supported in the direction of gravity on the sliding block.

By providing the second, approximately diametrically opposite equally formed device, an additional safety catch can now be accomplished. The fact that this device is diametrically opposite causes their actuator, which is rectilinearly adjustable from the same side as the other actuator, a blockage of the sliding block of the second device, which is opposite to the first sliding block, in the direction that leaves the other actuator.

In other words, one device serves to adjust the inclination, while the actuator of the other device blocks a beating in the opposite direction.

To adjust the inclination is basically only one of these devices mandatory, with the other is secured against beating.

Nevertheless, both devices are identical, but are arranged on two opposite sides of the axis of rotation.

Opposite means that these need not necessarily be exactly diametrically opposite, and it does not mean that the two slot openings must extend parallel, but the tangents can also form the legs of a V.

In a further embodiment of the invention, the actuator is designed as a screw which runs in a trained in the sleeve carrier thread.

This measure has the advantage that a stable actuator is provided by means of a screw, which is easy to handle. The necessary counterforce to the movable sliding block is absorbed by the thread. These components can be easily accommodated in the sleeve carrier, since this has in any case approximately the dimensions of the diameter of the sleeve. This thread can be cut into the body of the sleeve carrier, so that no laterally projecting construction measures are necessary.

In a further embodiment of the invention, the sliding block on a locking device over which the sleeve carrier and the lateral holder are clamped together.

This measure has the advantage that the position of the sliding block determined in the desired tilt position of the sleeve and thereby simultaneously sleeve carrier and side holder are clamped together.

This configuration can be chosen both when only one device is provided, then this acts at the same time as a high-impact protection, this configuration can also be provided when the two diametrically opposed slotted guides are provided, then this configuration serves as an additional locking device.

In a further embodiment of the invention, the locking device on an adjusting screw, which is received in a thread in the sliding block.

This measure has the advantage that can be determined by a structurally simple measure the sliding block.

In a further embodiment of the invention, a head of the adjusting screw and the sliding block each rest on shoulders in the oblong holes.

This measure has the advantage that, in turn, the captive holder, the displaceability and also the detectability of the sliding block is made possible by particularly simple and less bulky construction measures. Due to the fact that corresponding shoulders are cut in the oblong holes both on the side of the sleeve carrier and on the side of the holder, no measures are necessary which require laterally projecting structural measures over these components. These shoulders provide additional guides for both the screw and the sliding block. To enable the displacement, only this screw has to be loosened something and this then moves together with the sliding block when moving. By tightening the screw then the additional determination and the jamming of sleeve carrier is accomplished with lateral holder.

In a further embodiment of the invention, the sleeve carrier carries a arm bearing for awning arm.

This measure now has the considerable advantage that thereby the awning arm can extend in the respective inclination plane of the sleeve, since its inclination is automatically adjusted. This results in a particularly compact and slim-fitting cassette awning.

In a further embodiment of the invention, the lateral sleeve carrier and the lateral holder abut one another via a respective plate-shaped section which can be rotated relative to one another about the tube shaft axis relative to one another.

This measure has the advantage that stable base bodies are present through the plate-shaped sections, which lie against each other over a relatively large surface portion, but can slide past each other, so that laterally acting tilting forces are absorbed due to deflection of the canvas shaft due to gravity or due to the forces during extension can. By juxtaposing against each other then already relatively small clamping forces sufficient to prevent relative rotation of these two elements by gusts with extended awning.

In a further embodiment of the invention, the plate-shaped portions each have a central opening for receiving a journal of the cloth shaft.

This measure has the advantage that not only a centering but also the absorption of forces exerted by the cloth shaft journal can be evenly distributed to both elements.

In a further embodiment of the invention, one of the plate-shaped sections projects from a neck, which is received in the other plate-shaped section.

This measure has the advantage that not only a simple centered assembly by nesting these two plate-shaped Sections is possible, but that a correspondingly guided rotational movement in the tilt adjustment is possible through the neck.

In a further embodiment of the invention a plurality of radially aligned circumferentially offset by approximately 90 ° to each other arranged slot openings are provided in the holder.

This measure has the considerable advantage that one and the same holder can be used both for mounting on a vertical wall and hanging on a ceiling.

It is understood that the features mentioned above and those yet to be explained not only in the combinations given, but also in other combinations or alone, without departing from the scope of the present invention.

In FIGS. 1 and 2, the left outer end of awning provided with the reference numeral 10 in its entirety is shown.

The corresponding, not shown right outer end is designed to mirror image.

As can be seen in particular from FIG. 2, the awning 10 has a sleeve 12 which surrounds a cloth shaft 14 on which a cloth 16 is wound.

The cloth 16 is led out through a slot-like opening 18 of the sleeve 12 and retracted into this again.

For this purpose, as is known per se and need not be described here in detail, at the exit end of the cloth 16, a corresponding failure bar is provided which is in front of the slot-like Opening 18 comes to rest and over which the cloth 16 is withdrawn. The drop bar is then connected to a corresponding mechanism, for example, a known articulated arm, which accomplishes the raising movement in cooperation with a drive mechanism.

The drawing or winding this cloth 16 on the fabric shaft 14 is accomplished by the fabric shaft 14 is rotated about the fabric shaft axis 36, in the illustrated embodiment and in the view of Fig. 2 so to rotate the fabric shaft 14 counterclockwise.

These mechanisms are well known to those skilled in the art and therefore need not be further described in detail.

The awning 10 also has a carrying device 20.

As can be seen in particular from FIG. 2, this carrying device 20 has a lateral holder 22, which is fixedly connected to a holding rail 28 by way of two claws 24 and 26 protruding therefrom.

The support rail 28 is fixed in the illustrated embodiment on a vertical wall 30, for example, the outside of a building on a balcony to be shaded.

The lateral holder 22 has a plate-shaped portion 32 which has a central opening 34, the center of which lies in the cloth shaft axis 36.

In the plate-shaped portion 32 four radial slot openings 38, 39, 40 and 41 are provided. The four radial slot openings 38 to 41 are each arranged offset by 90 ° circumferentially to each other.

From the inside of each radial slot opening 38, 39, 40 and 41 jumps, seen from the outside, so the viewing direction of Fig. 2, inwardly before a shoulder, in which case only the shoulder 42 of the radial slot opening 38 is numbered, in the other same shoulders are provided.

The assembly of the carrying device 20 with the retaining rail 28 is a stationary, rigid and stable assembly.

On the inside of the holder 22, a sleeve carrier 50 is arranged, as it can be seen in particular from FIG. 1.

The sleeve carrier 50 has an approximately circular contoured plate-shaped portion 52 which has a nose 54 in the failure direction of the cloth, which carries an arm bearing 56.

In the arm bearing 56, a pin 58 is shown, via which on the arm bearing 56, an arm, such as an articulated arm, can be attached. The arm, not shown here, is thus pivotable about the longitudinal axis of the pin 58.

In the embodiment as an articulated arm awning, the outer dropout of the lower arm of the articulated arm is connected to the aforementioned drop bar, which is attached to the outer dropout of the cloth 16.

In the plate-shaped portion 52 of the sleeve carrier 50, a central opening 60 is provided, which is surrounded by a protruding neck 62 from the side facing the holder 22.

This neck 62 is inserted in the assembled state in the central opening 34 of the holder 22 fits, as shown in particular in FIG. 2 can be seen. In this state, the outer peripheral side of the neck 62 fits snugly on the inner peripheral side of the central opening 34, so that centering of the two plate-shaped portions 32 and 52 about the central cloth shaft axis of rotation 36 has occurred.

The plate-shaped portion 52 of the sleeve carrier 50 is flat and lies flat against the corresponding inner side of the plate-shaped portion 32 of the holder 22, as can also be seen in FIG.

In the inside of the neck 62, two diametrically opposed axial grooves 64 and 65 are provided, which serve to suitably receive a correspondingly shaped laterally projecting, not shown axle journal of the cloth shaft 14. The flat abutting parts lie in a plane of rotation 66. On the inside of the sleeve carrier 50 drainage openings 68 are still provided, which serve to drain any accumulated condensate from the sleeve 12.

The sleeve 12 is now mounted on the inside of the sleeve carrier 50 so that it is with its front-side annular surface on the plate-shaped portion 52 and this approximately flush circumferentially closes, as shown in FIG. 2 can be seen. Corresponding openings and screws serve to secure the sleeve 12 in a predetermined position on the inside of the sleeve carrier 50.

As can be seen in particular from FIG. 1, an approximately tangential oblong hole opening 70 is provided in the sleeve carrier 50, which extends tangentially to an imaginary turning circle 71 indicated by dashed lines in FIG.

Seen from the inside of the sleeve carrier 50, ie in the viewing direction of FIG. 1, a circumferentially extending shoulder 72 projects from the inside of the slot opening 70 inwards.

On this shoulder 42 and in the slot opening 70 rests a sliding block 74th

The sliding block 74 is formed so that it can reciprocate along the tangential slot opening 70, but due to the shoulder 42 can not, as seen from the inside outward, axially pass through the elongated opening 70.

In the sliding block 74, an adjusting screw 76 is received, the head 78 of FIG. 2 can be seen.

The head 78 of the adjusting screw 76 is received in the radial slot opening 39 of the holder 22 and the bottom of the head 78 rests on the corresponding shoulder 42 in this slot opening 39th

The adjusting screw 76 is in the axial direction, ie parallel to the fabric shaft axis 36 in the sliding block 74 on or ausdrehbar.

This assembly in cooperation with the shoulders in the openings forms a locking device 80.

Namely, the set screw 76 is tightened, the two plate-shaped portions 32 and 52 are pulled together in the axial direction and clamped together.

To move the sliding block 74 along the tangential slot opening 70, an actuator 82 is provided, which is designed as a screw 84 which runs in a cut in the plate-shaped portion 52 thread 86 (see Fig. 2).

From the outside, a corresponding groove groove 88 is cut in the plate-shaped portion 52, in particular in the region of the nose 54, in which the actuator 86 rests.

The front side of the screw 54 thus rests on this side facing the approximately cuboid sliding block 74th

As can be seen from Figures 1 and 2, a second tangential slot opening 90 is provided, which is arranged approximately diametrically opposite to the first tangential slot opening 70, but otherwise formed the same. That is, this slot opening 90 has a shoulder 92 on which a sliding block 94 rests. Also, this sliding block 94 is provided with an adjusting screw 96, the head 98 is received in the radial slot opening 41, as the particular From Fig. 2 it can be seen. Again, from the interaction of sliding block 94, the head 98 of the screw 96 and the shoulders 92 and 42, a locking device 100 is created.

The second tangential slot opening 90 is associated with an actuator 102 in the form of a screw 104, which runs in a cut in the body of the plate-shaped portion 52 thread 106. Again, a corresponding Kehlnut 108 is again provided on the outside of the sleeve carrier 50, in which the screw 104 is received.

The components in connection with the second tangential slot opening 90 in their entirety constitute a device 110 for adjusting the inclination of the sleeve 12.

The principle of tilt adjustment is to be described starting from the relative position between holder 22 and sleeve carrier 50, as shown in FIGS. 1 and 2.

In the relative position shown in Fig. 1 and 2, the inclination angle is 0 °, the cloth 16 is thus extended approximately horizontally.

The sliding block 94 in the second tangential slot opening 90 is located in its, in the illustration of FIG. 1 right outer sliding position, the screw 104 is screwed in at most far and is based on the sliding block 94 from.

The overturning moment of the arm received by the arm bearing 56 presses the screw 104 onto the sliding block 94.

If the screw 104 is now turned out, the sleeve carrier 50 rotates in the view of FIG. 1 counter to the direction of rotation about the fabric shaft axis 36, the nose 54 thus slopes downwards.

Relatively speaking, the sliding block 94 thereby moves to the left along the second tangential slot opening 90, as can be seen from the transition from FIG. 1 to FIG. 3.

At the same time, the sliding block 74 has moved from the apparent in Fig. 1 left outer position in the slot opening 70 corresponding to the right.

In Fig. 3 and accordingly in Fig. 4 screw 84 is shown already adjusted, but this can be done only at a later date.

From the transition from Fig. 1 to Fig. 3 it can be seen that the radial distance of the sliding block 94 with respect to the axis of rotation 36 has changed so that the radial distance in the position of Fig. 3 is smaller. Here he has approximated tangentially to the imaginary turning circle 71. The path difference or the relative radial movement is made possible by the fact that the sliding block 94 has moved in the radial direction along the radial slot opening 41, as can be seen by the transition from the position of Fig. 2 to Fig. 4. He has thus 41 can move radially inwardly along this slot opening.

If the screw 104 is rotated even further, the sleeve carrier 50 tilts further, as can be seen from the transition from FIG. 3 to FIG. 5, which is a transition from an angle of inclination of about 30 ° to an angle of inclination of about 60 ° equivalent.

From Fig. 5 it can be seen that the radial distance of the sliding block 94 has increased again from the fabric shaft axis 36, accordingly, in the transition from Fig. 4 to Fig. 6, the head 98 of the adjusting screw 96 of the sliding block 94 again radially after moved outside.

In Figures 5 and 6, the maximum inclination of the sleeve carrier 50 and thus the sleeve 12 is shown, which is approximately 60 ° from the horizontal in the illustrated embodiment. By correspondingly longer training but also a tilt angle can be achieved up to 90 °.

From the illustration of Fig. 5 it can be seen that now the sliding block 94 has arrived at the left end of the slot opening 90.

If the inclination is to remain in this position, the screw 84 is screwed in until it rests against the sliding block 94. This prevents a beating. When turning up, which would correspond to a transition from Fig. 3 to Fig. 1, the sliding block 74 would have to be able to move relatively to the left in the slot opening 70. This is then blocked when the screw 84 is screwed in so far that it rests against the sliding block 74.

Subsequently, the respective screws 76 and 96 are tightened.

If the inclination is to be reduced again from the position set in FIG. 5 or 6, the adjusting screws 76 and 96 are correspondingly released, the screw 104 is correspondingly screwed in and the screw 184 is turned off.

In the illustrated embodiment, the awning 10 is mounted so that the support rail 28 is mounted on a vertical wall 30th

If the retaining rail 28 is mounted on a ceiling, the cloth would then extend vertically from the position shown in FIGS. 1 and 2 and could then be "tilted" at most inward.

If then a corresponding inclination to the outside from the vertical are desired, the sleeve carrier 50 is offset by 90 ° attached to the holder 22, that is not, for example, as shown in Fig. 2, inserted into the radial slot openings 39 and 41, but to the 90 ° twisted slot openings 38 and 40th
