Description

My invention relates to one of a flow medium actuated display device.

In the case of conventional, pressure-medium-operated display devices, the movement of the individual »display elements either in the direction of the display positions or rather slowly away from them, so that these devices are not suitable for relatively high adjustment speeds, where a rapid sequence of signs or symbols on a scoreboard should be made visible »The proportionate

slow movement of the display elements is used in some Cases caused by the fact that the movement of the display elements in the one sighting takes place solely due to gravity, or that between the Walls of the display elements and the passages receiving these elements are provided a close match that delays the movement of the display elements.

The object of the invention is to provide an improved display device in which the individual display elements are arranged so that they move at very high speeds in their Anseigestellungen and out of these positions can be.

According to the invention, this object is achieved by that a display device with a base body with a number of passages in each of which a Display element between a retracted position and an advanced display position is slidably disposed; a corresponding number of each with a passage connected pipelines and control devices is provided, the via the pipelines selected display elements with pressurized Apply the flow medium and counter to the

Effect of a preload pressure that presses the display elements into their retracted position Advance display position

The pre-tensioning pressure generated by a flow medium with a pressure slightly above atmospheric pressure tries to move the display elements into their retracted positions. This bridge acts in a bit on the front ends of the passages of the display elements in verbis ^ tmg, located on the acseigeflache of the base body * so that no pressure is exerted on the rear areas of the display elements, these remain in te ⁵ Tr * i @ lgg € said position. Whether the force pushing the display elements into the closed position has to be overcome, the pressure exerted on the rear ends of the display elements must be pushed forward significantly greater than the pretensioning pressure exerted on the front ends of the display elements.

It has proven advantageous that between each display element and the associated passage Äpiel is provided so that on one side of the passage flow medium passed on the display element can get past to the other side of the passage «

The consequence of this is that the display elements on the back * slide out of the advanced display position from Preload pressure can be moved, while the opposite effect occurs when the higher pressure on the back of the selected, in the advanced Position to be displaced display elements is exercised · This is an inevitable and very fast Movement of the display elements from one position reached the other position

In the device according to the invention, each display element advantageously closes in full retracted position, the end of the associated drilling line substantially tightly in order to comply to ensure an adequate preload pressure acting on the front ends of the display elements This pressure can also be generated by a pressure directed in the opposite direction to the outflowing flow medium Devices are achieved that have an additional pressure medium that pressurizes the recesses may have a source

The display device shown in FIGS. 1 and 2 has a base body IO with a number of passages 11 arranged therein which run parallel to one another and are worked into the base body from the left side (FIG. 2). The ends of these passages lying on the right communicate with tubular connecting pieces 13 which are fastened in bores dos base body IO. Each connection piece is connected to a control unit 15 for the flow medium via a pipeline 14 . and a control device 20 · All emitters are connected to a common pressure medium source 21.

In each passage 11 a display element 22 is arranged tend same P, the "wipe in the axial Bichtung a rear retracted position shown on the right in FIG. 2 and a front, in P ₀ . 2 left display position shown is movable. The retracted position is determined by the abutment of the display element on the right side of the associated passage 11, while the display panel is determined by the inner surface of a transparent cover plate 23 which is sealingly placed on the hand 24 of the surface of the base body 10 on the left in FIG . This base body is provided with a recess 25 so that all the front ends of the passages communicate with one another. The cross-section of each indicator element is slightly smaller than the associated passage 11, "whereby there is little play between the walls of the passages and indicator element" so that pressurizing StromuogeaedluB can pass from one end of the passage 11 to the other end if there is a pressure differential between both ends of the passage.

As Fig. 1 shows, the passageways and display elements are arranged in such a way that in one direction offer elements and in the other, transverse direction, five elements are arranged parallel to one another on a display panel on which various characters and symbols are determined one after the other by advancing them Groups of display elements can be shown in their front display position and thus in contact with the transparent cover plate 23, while the other display elements are in their normal ^ retracted, invisible positions. 2 shows a certain group of display elements representing "$ 1® Count" 2 "moved into the display position. Many other alphabetic and / or numerical symbols can be created in HTML by advancing other selected groups of display elements 22 into the display position being represented.

An outflow connection 26 for the flow medium is provide with a laterally extended chamber 27, those in the lower left section of the body lies. The front end of chamber 2? is in communication with the recess 25, while the rear end
