SU93609A1 - Folding umbrella - Google Patents

Description

The subject of the invention is a folding umbrella with a telescopically sliding rod and three-piece V-shaped spokes, using a clip that freely engages the needle and is pivotally connected to a strut mounted on the movable umbrella sleeve.

In the known folding umbrellas of this type, the spokes are usually not easily and quickly moved apart when the umbrella is opened.

In the described folding umbrella, in order to facilitate the spreading of the spokes, traction is applied in the form of a cord attached at one end to the extreme pull-out part of the spoke, and the second through the crochet in the middle part of the spoke to the end of the upper part of the spoke.

FIG. 1 shows a view of a part of the folding umbrella in an opened state; in fig. 2 is the same when folded; in fig. 3 is an enlarged view of the details of the umbrella: view along arrow A in FIG. one; in fig. 4- view of the end of the bracket.

The umbrella stem consists of three tubes 1, 2, and 3 that are telescopically inserted into one another, which, after being pulled out, are automatically blocked by latches. At the upper end of the tube / rod still

washer 4 was reinforced, with which needles, having a V-profile and made telescopically sliding from three parts 5, 6 and 7, are hinged together.

A spacer 9 is pivotally attached to the movable m, ufte 8 of the umbrella, the other end of which is pivotally connected to the slider 10. To the latter, the middle part 6 of the spokes, having an eyelet at the end, is rigidly attached.

At the curved end 12 of the extreme extendable part 7 of the spokes, a cord 13 is fastened connecting the part 7 of the spokes through the eyelet 11 with the eyelet 12 at the end of the upper part 5 of the spokes.

approximately in the middle of the length of the strut 9 of the umbrella on the stand there is a hinged clip 15, having the form of a stud and the upper part 5 of the spokes freely covering its curved end 16. The bracket 15 is attracted to the strut 9 by the spring 17. The latter facilitates the automatic opening of the umbrella. When the umbrella is folded up (Fig. 2), all the springs 17 on the struts 9 are in the stretched state and, trying to shorten, push the movable clutch 8 upwards.

When opening the umbrella, all stem tubes are first pulled out. Then

the lower latch is released, and the coupling 8 under the action of the springs 17 rises, and the struts 9 extend the middle part 6 and the end part 7 of the girder, automatically opening the umbrella.

To lock the umbrella in the opened state, the protrusion 18 of the bracket 15, extending under the washer 4.

The umbrella is folded by moving the sleeve 8 down the umbrella stem and placing the spokes and the umbrella by hand.
