Description

This invention relates to road accessories.

The purpose of the invention is to improve ease of use by reducing windage and improving viewing conditions.

Fig, 1 shows an umbrella, a general view; in fig. 2 - umbrella shaft with handle, slit; in fig. 3 - umbrella with an additional dome, general view.

The umbrella contains a rod 1 with a handle 2, a system of spokes 3 with a protective dome 4, a sleeve 5 installed with the possibility of longitudinal movement along the rod 1, and supports 6, each of which is pivotally connected to the sleeve 5 and the corresponding needle 3. The umbrella is provided with a conductor 7 and a source of electric current 8 placed in the handle 2. The protective dome 4 is made of electrically conductive mesh material and connected by conductor 7 to an source of electric current 8. Rod 1 is made of electrically insulating material with a through channel 9 which eschen conductor 7 and the switch 10, configured as a za- abutting contact. In the electrical circuit connecting the protective dome 4 to the current source 8, a switch 11 is installed to change the polarity of turning on the dome 4.

In the closed position of the umbrella 8, the sleeve 5 interacts with the switch 10, opening the electrical circuit connecting the protective dome 4 to the current source 8. When the umbrella opens, the sleeve 5, moving along the rod 1, releases the closing contact of the switch 10, the circuit closes and the protective grid The dome 4 is connected to an electric charge. The electric field created by the charge of the protective dome 4 deflects the precipitating particles of the same charged particles. The required polarity of the charge of the grid of the protective dome 4 is provided by the switch 11.

According to FIG. 3 The umbrella has an additional dome 12, located under the protective dome 4, equidistant with it and made of electrical mesh material. The umbrella has two systems of spokes 3. The internal system of spokes 3 is connected by means of supports 13 to the sleeve 14, and the external system of spokes is connected to internal parts by means of tons 15. The dome 4 and additional dome 12 can be connected to one pole of the current source as well and to its opposite poles.

In the closed position of the umbrella, the electric circuit connecting the domes 4, 12 to the current source 10 is open, and they are not charged. When moving up the rod, the sleeve 14 by means of the supports 13 reveals the internal system of the spokes 3, which, being connected by the rods 15 with the external system of the spokes, opens the latter. In the extreme upper position, the sleeve 14, interacting with the switch 10, connects the domes 4, 12 to the current source 8 and is charged. Particles of precipitation that have passed through the grid cells of the dome 4 interact with the electric field of the dome 12. For example, when dome 4 and 12 are connected to opposite poles, precipitation particles that pass through dome 4 attract to the grid of dome 12 and flow down. The nets of the domes A and 12 are set with their cells displaced relative to each other by half the cell size, which increases the effectiveness of protection against precipitation, since the precipitation particles passing through the dome 4 are deflected by the electric field to the center of its cells and fall onto the grid domes 12. In case of neutral precipitations, it is advisable to message the dome 4 and 12 of the same charge, since
