Description

GERMAN

The subject of patent 866 080 is a screen that can be shortened and telescoped like a telescope Stick and roof pole parts, with main struts serving to support the roof frame and with Auxiliary struts that slide on one on the stick Auxiliary slides are hinged, and with hinged to the main struts:, for guidance on the inner Roof pole parts serving sliding sleeves that are attached to the inner ends of the outer roof pole parts sit, as well as with bulges on the inner roof pole parts, which the displacement of the sliding sleeves in the first part of the clamping movement counteract the unwanted pushing together of the roof poles when clamping to prevent as much as possible.

This braking effect requires relatively precise coordination. If it is too strong, he lets himself go It is difficult to push the umbrella together when shortening it, and it can happen when lengthening that the telescope parts are not pulled apart completely. If it is too weak, it does not fulfill their purpose.

Perfect coordination of the braking effect was possible with handmade umbrellas according to the patent 866 080 'can be easily reached, but made difficulties in series production. As a reason for this it finally turned out that the sheet metal sliding sleeves, if they were with the inner end of the outer roof pole piece and with the main strut when assembling by hand were riveted, experienced changes in shape, the extent of which differs from that expended during riveting Force depended and therefore scattered considerably.

This deficiency is remedied according to the invention in that the cooperating with the bulges Parts of the sliding sleeves consist of self-contained rings. Closed rings have a much higher strength than sleeves bent from sheet metal and accordingly slotted this strength is practically off the deformation during riveting, so that the degree of Braking effect only depends on the correct dimensioning of the width of the closed ring. This vastness but can easily be kept within tight tolerances in series production.

It is known, in the case of umbrellas that can be shortened, with roof poles consisting of three parts that can be pushed into one another to close the sliding sleeves at one end to form a ring. However, these umbrellas do not have any Bulges on the inner roof pole parts, which counteract the displacement of the sliding sleeves by braking. Therefore, the closed rings on the sliding sleeves do not have the same effect that the Invention aims.

The drawing illustrates an embodiment of the invention, namely shows

Fig. 1 schematically the frame of a shortenable umbrella,

FIG. 2 shows a longitudinal section through the mutually facing ends of the two roof pole parts in FIG slightly enlarged scale with omission of the strut,

3 shows a section along line IH-III in FIG. 2 in further enlarged scale,

Fig. 4 shows a section along the line IV-IV of Fig. 2 and

Fig. 5 is a view in the direction of arrow V.

The stick of the umbrella according to Fig. 1 consists of two telescoping parts 1 and 2, of which Part 1 carries the umbrella crown 3 and part 2 carries the handle 4. The means, the stick in the drawn drawn out Hold positions are not shown. A main slide 5 is movable along the stick. It can be in the lower position by a spring nose 6 and in the upper position by a spring nose 22 are blocked.

The roof poles of the umbrella consist of two telescoping parts 7 and 8, one of which Part 8 can be pushed into the hollow U-shaped part 7. Serve to guide the parts 7 and 8 together a ring 9 seated at the outer end of the part 7 and a sliding sleeve which is displaceable on the outside of the part 7 10. This sleeve has lateral extensions 11, between which a bent eye 12 of the outer roof pole part 8 protrudes. A rivet 13 connects the parts 10 and 8 to each other and is used for the articulation of Main struts 14, the inner ends of which are articulated to the main slide 5. Along the An auxiliary slide is movable on the 2nd floor. Auxiliary struts

16 are hinged on the one hand to the main struts 14 at 17 and on the other hand to the auxiliary slide 15. When the umbrella is relaxed and not shortened, the struts and roof poles lie close to the pole. Should he If the umbrella is opened, the main slide 5 is released and moved in the direction of the crown. Without special precautions, it can then it can happen that the roof frame does not open because of the main slide over the main struts 14 pressure exerted simply pushes the sliding sleeves 10 upwards along the roof pole parts 7. That work in the screen shown, as in patent 866 080, small projections or bulges 18 in the flanks of the inner roof pole part 7 opposite. These bulges keep the shift the sliding sleeves 10 temporarily open by braking and thus cause the roof frame to open. A sliding sleeve consisting of a stamped and bent sheet metal would be made from those specified at the beginning Reasons do not guarantee satisfactory results. The screen shown is therefore the sliding sleeve 10 at least at one end, but expediently at both, as more self-contained Ring 19 or 20 designed. Sleeves of this design can be mass-produced, for example Easily manufacture plastic with high accuracy. A hole 21 located in the ring part 20 is used to attach the cover. "> T - Γ PATENT CLAIM: Umbrella that can be shortened with telescope-like telescopic pole and roof pole parts, with serving to support the roof frame main struts and with auxiliary struts that on are hinged to an auxiliary slide that can be moved on the stick, and with hinged to the main struts, sliding sleeves that are used to guide the inner roof pole parts and sit on the inner ends of the outer roof pole parts, as well as bulges on the inner roof pole parts that allow the sliding sleeves to move counteract the first part of the clamping movement by braking, according to patent 866 080, characterized in that the parts of the cooperating with the bulges (18) Sliding sleeves (10) consist of self-contained rings (19 or 20) in a manner known per se.
