Push-button controlled TV channel selector

There are push button controlled television channel selectors are known in which By turning the push buttons used to select the individual channels, you can tune or fine-tune the relevant channel. · These channel selectors in accordance with the principles followed in the construction of radio receivers in the sail so built into the apparatus chassis that the Push buttons are accessible from the front of the receiver. As a result, the other sailing and switching organs, which are to be operated when operating the receiver, such as the volume, image tilt and brightness controls, the mains, the focus and tone shutter switches are grouped essentially according to technical or taste considerations, i. e. their control buttons are partly on the front or on the sides of the housing.

The firing system takes a different "path" and proposes, in the case of television channel selectors with push-button control, of the organs to be operated during the operation of the receiver, one control element and one switching element - such as volume control and network switch, image tilt control and focus switch, brightness control and tone switch - to sailor-switch combinations with push-button operation, the button of which corresponds to the push-button control of the channel

Selector accordingly when turning the controller and when moving to operate the switch, which together with the channel selector form a unified whole

Since in this way one control button is practically saved If the same button shape can also be selected for all buttons, this union of a channel selector stands out with one or more controller-switch combinations due to an extremely low space requirement and enables a architecturally favorable housing design, especially for asymmetrical ones Housing shapes · It is also used for fastening and mounting The necessary effort is significantly reduced, since a complete unit has to be installed instead of individual controllers and switches.

It is useful to combine the controller-switch combinations with a to equip optical display device · In order to make the switching status of the switch recognizable, all that is needed is a roller set at Moving the push button is rotated in the sense that in a viewing slot which the unit is covered by vomehin Plate, for example, a black area becomes visible instead of a white area. To identify the degree of adjustment of the Regulator can use a disc that participates in the rotation of the knob with a wedge that appears roughly black on a white background v / earth, which enters the viewing slot with increasing speed as the knob is turned. Both options can be used if necessary can also be combined so that both the switching status and the degree of adjustment can be displayed. The channel selector scale

In these cases one is called a thermometer scale with a execute IiTaI ze controlled by the pushbuttons of the channel selector, for their privacy protection, the display elements of the sailor switch combination ions form the extension.

The inflation and its details are given below the drawing explained in more detail for an embodiment.

Fig. 1 shows the complete unit in plan view,

Fig. 2 in side view.

In Fig »3 the unit is shown in the front view.

In the figures, Τ. · * T _g denotes the mutually actuating pushbuttons of the television channel selector, the pressing of which enables the individual channels to be selected and the rotation of which allows tuning or fine-tuning to be carried out in the relevant channel. In addition to these push buttons, three further push buttons T._, T ₁ - "T ₁₂ g ^leic ke ^r form are provided, each of which has a rotary _{glider R-" R 2} and a toggle switch ^ 10 ~ ^ 1 2 ^to £ ^eox * ^ine ^ ^is ^ · These controls and switches, which belong to the other organs to be operated during the operation of the television receiver, are combined into regulator-switch combinations with push-button operation, the knob of which corresponds to the push-button control of the channel selector when turning the controller and when moving the switch allowed to operate. The frame U of the channel selector forms its support, so that a uniform

The result is a whole, the buttons of which, in principle, are equally 'quiet to operate'

Each Hegler switch combination is equipped with an optical display device. The display devices are designed here as rollers W ₁₀ , W ₁₁ , W ₁₂ , which are rotated when the push buttons are moved in such a way that a plate P which covers the unit towards the front is held _{in a viewing slot T 10} , "V ₁₁ , V ₁₂ A black surface appears on a white surface · The IC channel display is similar. A wider roller W is used for this, which is controlled by the push buttons of the channel selector, so that a progressive marking is visible in a viewing slot V like a so-called thermometer scale The viewing slots T ₁₀ or T ₁ and V _{12 form} the extension of this viewing lock V, so that the uniformity of the structure is also preserved in this respect.

Claims (5)
