Abstract
Abstract Turners for communication carriers, especially for radio and television sets, having a number of switches which can be shifted from the off-position to the on-position against the action of a spring. The switches are retained in the on-position by stop members interconnected in such a manner that, when one switch is shifted to its on-position, all of the other switches are released for return into their off-position. The switches take the form of toggle switches comprising switch buttons rocking about a common axle and having a circular notched section provided concentrically with their axle of rotation.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
176 words
A tuner for communication carriers, in particular for radio and television sets, comprising a number of switches which may be shifted from their off-position to their on-position, first spring means operatively associated with the switches for returning the latter to their off-position, which switches are retained in the on-position by stop means engageable therewith, whereby, when one switch is shifted to its on-position, all of the other switches are released for return into their offposition, characterized in that the switches are toggle switches having switch buttons pivoting about a common axle and provided with stop notches along a circular section extending concentrically to said common axle, said stop notches being engageable by said stop means, each including a pawl having a nose, all of the pawls being mounted on a common rod extending in parallel to the common axle, said rod being rotatable about its longitudinal axis, and the rod being operatively connected with and loaded by a second spring means for pivotally moving the rod to retain the pawls in engagement with the stop notches.
Claim 2
Dependent Claim
176 words
A tuner for communication carriers, in particular for radio and television sets, comprising a number of switches which may be shifted from their off-position to their on-position, first spring means operatively associated with the switches for returning the latter to their off-position, which switches are retained in the on-position by stop means engageable therewith, whereby, when one switch is shifted to its on-position, all of the other switches are released for return into their offposition, characterized in that the switches are toggle switches having switch buttons pivoting about a common axle and provided with stop notches along a circular section extending concentrically to said common axle, said stop notches being engageable by said stop means, each including a pawl having a nose, all of the pawls being mounted on a common rod extending in parallel to the common axle, said rod being rotatable about its longitudinal axis, and the rod being operatively connected with and loaded by a second spring means for pivotally moving the rod to retain the pawls in engagement with the stop notches.
Claim 3
Dependent Claim
57 words
A tuner in accordance with claim 1, characterized in that the switches include the switch buttons operatively connected with the first spring means by pins and slots with contact slides which can be displaced relatively to the common axle of said switch buttons, and the first spring means includes return springs which act upon the contact slides.
Claim 4
Dependent Claim
54 words
A tuner in accordance with claim 1, characterized in that each switch includes a switch button operatively associated with at least one contact slide on the side thereof which can be displaced from a neutral position in opposite directions and which, while in a neutral position, keeps the switch button in a central off-position.
Claim 5
Dependent Claim
29 words
A tuner in accordance with claim 3, characterized in that two contact slides are assigned to each switch button and are arranged on both sides of the switch button.
Claim 6
Dependent Claim
62 words
A tuner in accordance with claim 4, characterized in that the contact slides are arranged between two neighboring switch buttons and are directly adjacent to each other and that they are provided with slots for drive pins disposed on the switch buttons, said slots being sufficiently spaced to ensure that they will not considerably overlap in any position of the contact slides.
Claim 7
Dependent Claim
59 words
A tuner in accordance with claim 1, characterized in that each of the switch buttons comprises a drum seated on the common axle and carrying a radially projecting wiper which extends through an opening in a case cover, and said cover having said openings through which certain sections of the drum, which may indicate the switch functions, are visible.
Claim 8
Dependent Claim
38 words
A tuner in accordance with claim 6, characterized in that a drum sector of the switch buttons corresponding to the angle of traverse of the switch button extends into the opening for the wiper provided in the cover.
Claim 9
Dependent Claim
60 words
A tuner in accordance with claim 6, characterized in that each drum is a hollow body comprising in its interior at least one concentrically supported dial cylinder carrying marks which are visible through a window disposed in the drum jacket, and being in engagement with a drive member which extends through an opening in the drum jacket opposite the wiper.
Claim 10
Dependent Claim
29 words
A tuner in accordance with claim 8, characterized in that the dial cylinder carries on its one end a toothed rim which is engaged by a slidable toothed rack.
Claim 11
Dependent Claim
44 words
A tuner in accordance with claim 8, characterized in that a potentiometer with a slider running on a threaded spindle means is arranged below the drum, and the drive member for the dial cylinder, in particular the toothed rack is connected with said slider.
Claim 12
Dependent Claim
81 words
A tuner in accordance with claim 10, characterized in that two dial cylinders each coupled to one potentiometer slider are arranged side-by-side within the drum, and the drum of the switch button comprises two openings which are arranged on both sides of the wiper and which are hidden by the case cover when the switch button occupies its central position, whereby each of said potentiometers may be selectively thrown into a circuit from their neutral position by actuating the switch button.
Claim 13
Dependent Claim
85 words
A tuner in accordance with claim 10, characterized in that the threaded spindle means may be coupled with a central tuning device and that their ends carry clutch members which may be displaced in the longitudinal direction of the spindles and which are retained out of engagement with a matching clutch member of the central tuning device by means of an associated contact slide, when the switch button is in its off-position, while being released for engagement when the contact slide occupies any other position.
Claim 14
Dependent Claim
19 words
A tuner in accordance with claim 10, wherein the drive member connected with said slider is the toothed rack.
