The invention relates to a shortenable umbrella with telescopic ep pole and roof pole parts and. with main and hi-if struts V:. - ^ V _ "- ■ -"

There are shortenable umbrellas of the above-mentioned type known which are designed so that the umbrella crown is connected only to the upper ends of the inner roof pole parts and the outer roof pole parts which can be pushed in at the inner end via a hinge sleeve of one each with the Main slide connected longwall © are held. The auxiliary ss tr are here, led from the upper end of the stick part to about the middle of the main strut. With such a shortenable umbrella, the umbrella crown can be moved independently with respect to the end of the pole. · During locking the shield of-the prolong need "only the ^one roof rod parts to be pulled shortened position to the extended position This movement can look very _easy..

Obstacle. With a slight shifting movement of the main slide the roof pole parts are radially outwards because the auxiliary struts are at a fixed point, namely support the upper end of the stick.

The object of the invention is to provide the collapsible screen of the above mentioned type, i.e. the shortenable umbrella with the hover crown, with regard to the telescopic ability of the To further develop stick parts and the roof pole parts in essential points in order to handle the 'shortenable To improve the umbrella. With the telescopic frame / i mit_der The roof pole parts and floor parts are not floating crown telescoped at the same time, but one after the other. The roof pole parts are pulled apart first. When the frame is subsequently opened, the lower floor slides out the upper floor out. According to the invention it is provided here that the stick parts can be locked together in an intermediate position except in their end positions. Here, the intermediate lock should be arranged near the end position be in which the stick parts are completely pushed into one another. In this way it is achieved that when the umbrella is closed, the entire handle remains accessible and is not covered by the roof poles. The handling of opening and closing the umbrella with the floating crown is more comfortable and safer.

For pocket umbrella frames with floating crown, which are placed in the umbrella stand when closed sölleni there is the - 'danger - that the roof pole parts shorten unintentionally; the frame can be

provided to prevent this from happening. This can be done in the way happen that the massive, badger tang part just before the rare end facing the other badger tang part a widening and the U-shaped roof pole part to the Thighs has a narrowing. The U-shaped roof pole part can also be at two opposite points have outwardly pressed bulges over which the running hinge sleeve must be moved. The two Types of locking the roof pole parts have the advantage that the resilient properties of the roof pole or of the hinge can be used and the dimensional coordination does not require any particular accuracy interlocking roof pole parts achieved a braking point, by the safety of the screen slipping together when setting in an umbrella stand or the like. is prevented. ··.

With the shortened umbrella with floating crown it can happen that with very, tightly cut fabric covers opening of the frame in the last phase can be considerable Hand strength required until the slider is locked. In order to avoid these coincidences that occur when assembling the Umbrella, i.e. if the umbrella frame is provided with the fabric

The shortenable umbrella 1 with the floating crown has the telescopic pole parts 2 and 3 and the telescopic pole parts 2 and 3. removable roof pole parts 4 and 5. The inner 'roof rod members 5 are pivoted to a floating crown. 6 The main struts 7, which are hinged at their other ends to the slide 8, engage the inner ends of the outer retractable roof pole parts 4. Auxiliary struts 5 are also provided, one end of which is hinged to the cane crown 10, which is connected to the cane part 3. The other end of the auxiliary struts 9 is hinged to the main strut 7, for example over about 2/5 of the length of the main strut or also roughly in the middle of the strut length. . '

The two pole parts 2 and 3 can be locked in three different positions by a latching connection of a special kind. In position I, the stick parts and ~ 5 are locked together in the fully extended position. This locking is very secure and is released when the umbrella is closed when the slide 8 slides over the button 11 of a spring 12 located inside the stick 2 and pushes it back into the inside of the stick. At this moment the closing movement can take place under the influence of one; applying manual force push the inner tube 2 into the outer tube \ 3. The locking button 11 then finds a new locking point in position II. The total length of the stick resulting from this is chosen so that the entire handle remains free and is not covered by the ends of the rails Floor still pushed into the outer floor 'J> '. The rarity button 11. reaches position III on dana.ch

There must be sufficient holding force at the steep incline, since a folded umbrella frame is carried on the loop and must not slide apart too easily. The stick lock is only released in position I by fully pressing the button 11 inwards, which is carried out by a run-up surface IJ> in the slide. In positions II and III, the locking of the stick parts to one another can be released under the effect of a force exerted by the hand, for example a light blow. The diameter of the holes in the pole parts and the shape of the locking button 11 are matched to one another.

So that in the pocket umbrella frame with floating crown, the extended roof pole parts also remain in this extended state when the umbrella is placed on the floor, for example in an umbrella stand, the roof pole parts are locked to each other by means of a gooicnote device. In the embodiment of FIG. 5 - 7 is the outer roof rod part 4 which is designed as a solid rail, just before the end at which the main strut is hinged to 7 _x by means of a flattening a mutual bulge lA, the färmigen U-into the profile of the Roof pole part 5 can slide freely. The roof pole part 5 receives a narrowing 15 at a suitable point by notching the profile edges. When pulling out the roof pole parts 4 and 5, the bottleneck between 14 and 15 can be overcome by a not very great force. When parking a closed umbrella, however, this weak locking force is sufficient to slide the roof pole parts 4 and

to prevent. The main strut 7 is articulated in a known manner to the roof pole part 4, the hinge 16 being connected to the hinge sleeve VJ along the length of the. Roof pole part 5 ^Λ - can be pushed into place. ·

In the embodiment of FIG. 5, the U-shaped profile of the roof tangon part 5 is pressed outwards at two opposite points l8. When the umbrella is opened, the running hinge 17 is pushed over the covered area Io with a brief spring deflection. In this position, again a good holding force zwischen'den roof rod parts 4 and gives Ijoe-n predetermined position ^so: dai3 or the like of the screen at a Zusamrnenrutschen setting in an umbrella stand. will certainly be prevented. In both cases, the resilient figure of the U-shaped profile loop or the hinge is used. Such a locking device is simple and effective.

In the case of telescopic frames with a floating crown wire, the floating crown 6 is pressed against the stick crown 10 in the open and pushed together position. A fold of fabric on the screen cover can get between the contact surfaces of the beiuenjironen. Correspondingly, the top of the stick crown 10 is designed to be spherical in order to keep the contact surface as small as possible. In this way, a jammed fabric fold can be easily pulled out. four den.- The stick crown 10 is mounted in the associated stick j5 so that it can be moved lengthways. For this purpose, provided in the floor 10, a crown Längstc-HLI tE ^ ^ -ϊ d.urch which a pin 20 is ürrt overall 1, Oer both sides-in the V / anddng the tock is mounted partly S. The displacement can be about 10 to 20 mm. Due to the possibility of longitudinal displacement of the cane crown towards the cane part 3, the floating crown on the cane crown comes to rest earlier than inside the cane crown

is fixedly attached to the stick part 5. Through this the umbrella cover does not need to be overstressed in the tightening if this is for the umbrella frame TOO tightly tailored is. The umbrella can be lighter open .λ The displacement of the cane crown 10 is thereby. achieved that the auxiliary struts 9 have a corresponding force both in the direction of the displacement of the cane crown carry out the opening process of the umbrella. During the closing process of the umbrella, the stick crown is automatically shifted in the direction of the stick part 3.
