NEW OLD UMBRELLA

Folding umbrella is much more comfortable, against this one can hardly argue. Meanwhile, to alter a simple umbrella in the transforming is not so difficult. First of all, the umbrella must be almost completely dismantled, that is, remove the cloth, remove the wire ring — joints of the spokes and struts. A pair of “needle — brace” parse should not be, it can be modified and assembled.

 

The revision is to shorten the spokes and brace (POS. 1). Coming to the Central rod of the umbrella ends of the spokes flattened and drilled holes the same diameter, and cut in pieces, and their opposite ends are bent as shown in POS. 1.

 

After modification of the ends of the spokes should be podkalit: heating red hot and cooling in water.

 

The next stage is the production of ten joints. You can cut them out of tinplate with a thickness of 0.5—0.8 mm (POS. 2) and bend the mandrel. Further, the hinges are fixed ia pin — crimped in a vise. Then, in the joint of the drilled hole of Ø 1,0—1,2 mm.

 

You will have to make ten half-spokes (POS. 3), the material for which is wire-type OVS Ø 2 mm. One end of each pawspice flattened and bent (Fig. 3) and drilled hole Ø 1-1,2 mm. Then the item is inserted into the hinge, where and is secured with axis — cut steel wire of appropriate diameter. Make sure that the backlash was minimal, otherwise, reworked umbrella will last a long time. The axis did not fall out of nests, it is necessary to rasclaat.

 

 

The Central rod of the umbrella is necessary to truncate (POS. 5) put on a pre-machined flange (POS. 4). Three rods (POS. 6) are inserted into the notches of the flange and secured it with a wire ring axis. Their purpose is to hold the umbrella in folded position. The recess flange is sealed a tube of porous rubber.

 

And the last — modified parts of the umbrella cover restored and painted the new parts. You can now proceed to final Assembly.

 

The spokes and struts are inserted in place and locked with a wire ring axis, the material of the dome thread is attached to the frame — the umbrella ready (POS. 7, 8).

 

For rework, it is desirable to use an umbrella with a gentle dome, as the upgrade makes the dome more prominent.
