to a :, bev the JQapp articulation point of the outer roof rod section advising arm engages the sweeter roof rod section, with the articulated connection point between the control strut and the outer roof rod section being assigned a free junction located in the direction of the clan.

A corresponding design is the subject of an older one Registration of the applicant.

Such a structure leads to an economical, stable design of a generic sunshade that can be shortened with an inexpensive, reliable control of the outer roof pole section. The roof fabric tension itself also acts as a stabilizing factor, as it causes the control strut and its adjacent roof pole section to bulge. Due to the clearance taken into account in the handlebar parallelograin, a smaller actively controlled tilt angle is required in the opening or closing phase than is normally required for a stretched position. This results in a space-snarling flat position in the collapsed ^1st , shortened state and an optimally stabilized extended position in which the control strut and its neighbors

Roof pole section occupy a relatively large distance from one another.

The object of the invention is to design a generic screen with a simple, stable design so that the roof poles are stretched much earlier, before the roof fabric tension occurs and the rest of the time Opening movement of the slide is independent of the roof fabric tension and stabilizes the roof curvature causes corresponding bending deformation of the middle roof pole section.

This task is solved by the irr. Claim 1 specified invention.

The subclaims specify further favorable configurations of the solution according to the invention.

As a result of such a configuration, while maintaining the same basic components of a generic umbrella additionally achieved the essential advantage that the roof poles have already stepped into their extended position before the roofing material as a determining factor in the sense of the curvature »-

At the upper end of the umbrella shaft 1 sits the top plinth 7 which closes the crown crown. This appears as a "he. Cross-section of the umbrella frame determines the component pu?

Roof poles 8 are articulated in the area of diametrically opposed wings 7 'and 7' ^{1. The usual binding ring 7 1} ' ¹ , which represents the joint axes of the roof poles 8 and which is embedded in an annular groove 7' ¹ · 'of the plate 7, is used for this articulation.

A three-way division is also preferably used with regard to the roof poles 8. They consist of the crockery crown side Section 8a, the middle section Pb and the outer section 8c.

The two inner roof pole sections are Ra and 8b telescopic. To achieve this telescope: 'Idum the crown-side roof pole section 8a consists of U-

The canopy-side The end of this central roof rod section 8b engages via a pivot pin 9 on one on the section 8a displaceable bearing Io, while the other end of this roof rod section 8b has a pivot pin 11 with the outer roof pole section in connection stands.

The control ^{strut I 1} I and the middle roof rod section 8b form the longer links of a four-bar linkage I ₃ while the arm l6 and a section of the main slide strut 13 form the shorter links of this four-bar linkage.

The joint connection point between the control strut Ik and the outer roof rod section 8c has a clearance in the folding direction that goes beyond the usual joint play.

To allow entry of the flattened end of the control strut 1 * 1. This U-shaped configuration leads to pure stabilization of the pivot area and thus to a lateral support that favors the extended position of the connected parts, since the U-legs 22 form a kind of joint shoe over practically the entire length between pivot pin 11 and U-pivot pin 17. The remaining length of the U-legs 22 of the arm 19 is connected to a bushing 24 ^{, which receives the outer roof rod section} 8c and is firmly connected to it.

The opposite end of the control strut 14 is also more folding, taking into account Needs trained. The flattened one, the corresponding bearing eye for the pivot pin having the end protrudes into the U-space of the U-profile manufactured main slide ^ strut 13.

The auxiliary slide strut 19 is also made from a U-profile. One of these strivings takes one known opening aid 28. Your rebounding Klinkenkcpf 29 acts with a paste opening on Floor 1 together.

The main slide 12 is equipped with a pawl provided with a push button 3o, which is

engages the tensioned state of the umbrella in a detent of the umbrella pole.

If the umbrella is to be closed, starting from the open position according to FIG. 1, the main slide 12 is to be pulled in the direction of the umbrella handle 28 by actuating the pushbutton 30. Taking the auxiliary slide 18 with it, the main slide strut 13 finally rests against the pole 1 at a constantly changing, ie decreasing, angle to the pole axis zz. As a result, the control strut I ¹ I is moved in the direction of arrow b. This leads to a pivoting of the arm 16 about the pivot pin 11 of the central roof rod section 8b, so that the outer roof rod section 8c forcibly folds towards the central roof rod section 8b. The position in this regard is not shown again in particular in the drawing, since it results approximately from FIG. 3.

axis z-z, which approximation is partly due to the displacement of the main slide and to a certain extent Measure by embracing the entire bundle of poles is the shortening of the umbrella pole made by exerting a corresponding pressure force. There is one after that Position before, in which the main slide in the not shown annular space of the umbrella handle 27 retracted and the auxiliary slide 18 directly against the underside of the top plate 7 stepped. The main slide he strive 13 are tied to the umbrella stick 1. The docking of the sections 8c is possible in a close system.

To open the umbrella, the umbrella pole is first extended. After this, the position shown in FIG. 3 is approximately present. The clearance between the outer roof rod section 8c and the control strut 14 leads to the fact that the outer roof rod sections 8c, possibly supported by the roof fabric 32, advance into an unfolded position that facilitates the opening of the umbrella, in which the quadrangular joint I already has an opening that facilitates the opening of the umbrella Intermediate position: ^r mt.

With further displacement of the main slide 12 on the crane side, the control strut I ^ now effects the forced disengagement of the outer tach rod section 8c. This opening movement is further ^{facilitated by the opening aid 2 P} , which, under the effect of an intermediate stop of the auxiliary slide 18, brings about a preferred actuation of the roof poles. The roof bars 8 reach the intermediate position illustrated in FIG. 5. In this position, the outer roof bar section assumes a stretched position relative to the two inner roof bar sections 8a and 8b. In this position, the roofing material itself is still loosely on the roof poles 8 that support it. If the main slide 12 is shifted further on the crown side, the main slide strut, which is steeper to the pole axis zz, exerts a sustained tensile load on the control strut I ¹ J. This not only leads to the stretched alignment of the foldable roof bar section that is maintained under forced control, but also to an outward displacement of the bearing Io and clan.it of the central roof bar section hinged to it.

section 8b. This extension, which of course has different lengths in flat _{umbrellas 5,} brings the central roof pole section 8b into the ¹¹ foIbung position illustrated in FIG. The overall curvature of the roof pole is therefore not based exclusively on the tension of the roof covering material.

While the control strut I ¹ J is under permanent tensile load in this clamping position, the roof rod section 8b arching over it is under pressure load.

Since the length of the slot 21 is about the difference Al corresponds to between the distance A and the control strut length L, lies in the 3ffnungs- tzw. Intermediate closing phase (cf.? ir. 3; a smoothly steerable] C-arm square I.
