Interchangeable umbrella handle. Patented in the German Empire on March 14, 1923.

The object of the invention is an interchangeable umbrella handle, which by conical Ring body is pressed onto the umbrella pole. Of the known such fastenings The object of the invention differs in that two nested Clamping sleeves are used that have one of these two on the outer end Bushes against each other shifting clamping nut and at the inner end with each other working, conical and ■ longitudinally slotted rings are provided.

■ The subject of the invention is in the drawing shown, namely show:

Fig. Ι the inner clamping sleeve,

Fig. 2 the outer clamping sleeve,

Fig. 3 the clamping nuts in view and plan view and

Fig. 4 shows a cross section through the exchangeable umbrella handle.

The removable umbrella handle conceals in its cavity the two clamping sleeves α and b, which encompass the end of the umbrella pole. Of these clamping bushes, the inner one (o) has on one

At the end a conical ring h widening towards the outside with longitudinal slots and at the other end a screw thread outside. The inside of the sleeve is smooth because it rests against the umbrella stick. The other sleeve b, on the other hand, is smooth on the outside, since it comes to rest in the cavity of the handle, and at one end has a corresponding hollow-conical ring shoulder g with longitudinal slots on the inside.

The other end of this sleeve sits loosely on a shoulder of the clamping nut c, the internal thread of which cooperates with the external thread of the inner sleeve α. The clamping sleeve α is drawn into the clamping sleeve b through this nut. When the clamping nut c is tightened, the cone h engages in the cone g , whereby the clamping bushing a denotes the umbrella pole and the clamping bushing b

so umbrella handle stuck.

In order to prevent the two bushings from rotating in the bore when tightening the clamping nut c , the clamping bushing α carries a guide screw d which runs in the recess e of the clamping bushing b . The head of the guide screw d protrudes somewhat into the groove / located in the bore of the handle.

When assembling the handle and stick, the first thing is to push them together Clamping bushes with clamping nuts loosely screwed on to the base inserted into the handle, then the handle is pushed onto the umbrella pole and the clamping nut is tightened by a few turns. handle and stick are then firmly connected to each other.

When producing the clamping nut c , the hole for the passage of the umbrella pole is only kept about 5 mm in diameter. Depending on the thickness of the umbrella pole, the opening is then drilled out accordingly.
