Claims

1. A remote controller for televisions and/or video recorders/players, comprising a housing having an upper shell and a lower shell, said upper shell being provided with a plurality of different slots adapted to receive different sizes of push buttons, a printed circuit board with electronic parts disposed inside said housing, and a circular channel adjustment control and a volume adjustment control traversing respective slots on said upper shell, each of said circular channel and volume adjustment control being mounted pivotally to a respective cylindrical shaft on said upper shell of said housing apart from the printed circuit board, and each being provided with an opposing forward lug and rear lug protruding outwardly from a periphery thereof, the lugs oriented to selectively contact members of said printed circuit board when the respective circular channel and volume adjustment control is pivoted to signal changing the channel or volume and limiting the extent of the pivoting of the respective adjustment control.

2. The remote controller of claim 1 wherein each of said circular channel adjustment control and volume adjustment control are provided with a plurality of transverse ridges disposed at the periphery thereof.

3. The remote controller of claim 1 wherein said circular channel adjustment control and volume adjustment control are made of rubbery material.

4. The remote controller of claim 1, where the shaft is elongate and extends axially in a top plane of the upper shell of the housing.

5. The remote controller of claim 4, where the surface of the housing having the plurality of different slots is elongate and where each shaft is oriented with its longitudinal axis transverse to the longest dimension of the surface.

6. The remote controller of claim 4, where the circular channel adjustment control and volume adjustment control each protrude proud above all other buttons of the remote controller.

7. The remote controller of claim 1, where the circular channel adjustment and volume adjustment control have a circular profile and the lugs protrude from the circular profile.

8. The remote controller of claim 1, where the lugs each comprise black conductive disks that selectively contact respective ones of the contact members of the printed circuit board.

Description

(1) These and other objects and advantages will come to view and be understood upon a reading of the detailed description when taken in conjunction with the accompanying drawing hereof.

(2) FIG. 1 is a perspective view of the remote controller for televisions, video recorders/players according to the present utility model; and

(3) FIG. 2 is a partial sectional view when taken along line 2-2 of FIG. 1.

(4) Referring now to the several views of the drawing, wherein like reference numeral designates same part throughout. Shown is a utility model for a remote controller for televisions, video recorders/players and the like generally designated as reference numeral 10.

(5) Said remote controller 10 comprises an elongated generally flat housing 11 being defined by a pair of upper and lower shell 12 and 13. Said upper shell 12 is provided with a plurality of different kind of slots 14 adapted to receive different sizes of push buttons 15 intended for changing channels and for setting up different kinds of program activities, such as on/off button, mute button or for accessing the menu options.

(6) Inside a typical remote control, a printed circuit board (not shown) is provided. Said circuit board is a thin piece of fiber glass having a thin copper wires etched onto its surface. Electronic parts such as chips, transistors, etc. are also assembled on said printed circuit boards and are connected to said copper wires.

(7) The different push buttons 15 are made of thin rubbery material 16 and are each provided with black conductive disk 17 at the bottom thereof. Said black conductive disk 17 are spacedly disposed from the contact member 18 located on said printed circuit board, such that when the push button 15 is pressed downwardly, the black conductive disk 17 touches said contact member 18, thus is connected to the chip which senses the engagement of the particular button thereof. This step would produce a morse-code-line signal specific to that button. The transistors then amplify the signal and send them to a light emitting diode LED (not shown) which is usually located at one end of the housing 11, and translates said signal into infrared light that is received by the television/video recorder or player's sensor.

(8) As best seen in the drawing, the novel feature of this utility model is in the provision of a pair of individual circular channel and volume adjustment controls 19 and 19a made of rubbery material, and each traversing a pair of spaced apart rectangular slots 20 and 20a on said housing 11, and respectively connected pivotally along at their centers with extending shafts 21 secured to said housing 11. Each of said channel and volume adjustment controls 19 and 19a are defined by a circular rubber member having a plurality of transverse ridges 22 along the periphery thereof and a pair of opposing forward lug 23 and rear lug 24 protruding outwardly from the periphery thereof. Said forward lug 23 and rear lug 24 are each provided with black conductive disks 15 that communicate with their respective contact members 18 and 18a of said printed circuit board. By means of pushing the circular channel and volume adjustment control 19 and 19a, the forward lug 23 would push the front contact member 18 to change an existing channel to higher channels or increase volume of the television or video recorder/player and the like. The retraction of said channel and volume adjustment control 19 and 19a, the rear lug 24 would push the rear contact member 18a to adjust the program of the television to lower channels or decrease the volume thereof.

(9) While this invention has been particularly shown and described above, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope and spirit of the invention encompassed by the appended claims. For example, said circular rubber member may also be adapted to be used in all buttons of the remote control.
