Description
ROTATING CONTROL APPARATUS
OF SAFE SEAT PLATE FOR TELEVISION RECEIVER
The invention is related to provide a control apparatus for rotating a safe seat plate of a television receiver, leftwardly and rightwardly.
Generally, a television receiver has been safely placed on a shelf or a properly fixed furniture, or mounted on a wall so as not to be rotated. When this television receiver could have been watched away from its front, it gave viewers much troubles to rotate the television receiver through manual works according to their watching position. Also, the rotation of the television receiver had not been easy.
Accordingly, the object of the invention is to provide a rotating control apparatus for facilitating television audiences to adjust the watching angle at their options.
The other object of the invention is to provide a rotating control apparatus for returning a television receiver to the original position, automatically, when the television receiver is not given audition.
According to the invention, a rotating control apparatus is provided with a safe seat plate including a fixing means and a rotating means mounted on the fixing means to be rotated leftwardly and rightwardly.
The rotating means is rotated leftwardly and rightwardlywithin an optional range, for example about 270 degree, according to the forward and rearward rotation of a motor based on the orders of audiences.
The rotation orders of a motor may be issued using a switch or a remote controller.
When the rotating means is rotated dependent upon the viewers' orders, a rotating direction of the rotating means is previously discriminated. Then television receiver is returned to the original position in the opposition to its rotated discriminating direction as soon as it is turned off. Thus, the television receivers are positioned toward the front during their non-use.
The invention will be described in detail below by the reference to the accompanying drawings, in which: Fig.l is a perspective view showing the positioning of a television receiver on a safe seat plate adapted to a rotating control apparatus according to the invention; Fig.2 is an exploded perspective view showing a safe seat plate adapted to a rotating control apparatus of the invention;

Fig.l is a perspective view illustrating the position of a television receiver on a safe plate adapted to a rotating control apparatus of the invention, Fig.2 is an exploded perspective view of a safe seat plate and Fig.3 is a view illustrating the rotation of a safe seat plate.
Fixing portion 1 is provided with rotating portion 2 moving leftwardly and rightwardly with television receiver 3 being positioned thereon, safely. A motor (not shown) and shaft 4 are mounted in the thickness portion of fixing portion 1 to rotate shaft 4 according to the operation of the motor. To the bottom surface of rotating portion 2 there is fixed supporting bar 5.
Supporting bar 5 is fixed to shaft 4 to rotate supporting bar 5.
Switches 6 and 7 are mounted on the top surface of fixing portion 1 to detect the leftward and rightward rotation of fixing portion 1. When rotating portion 2 is rotated leftwardly and rightwardly, both ends of supporting bar 5 can be contacted with switches 6 and 7 to turn on them. Also, switches 8 and 9 are mounted on the top surface of fixing portion 1 to detect the completion of the leftward and rightward rotations of rotating portion 2.
Fig.4 is a block diagram illustrating a rotating control apparatus according to the invention. Transmitting portion 10 sends commanding data of leftward and rightward rotations and turning on and off of television receiver 3 through ultraviolet light emitting diode 101 to amplifying/filtering portion 11.
Amplifying/filtering portion 11 receives the commanding data of ultraviolet light receiving diode 111 to amplify/filter them. The output signals from amplifying/filtering portion 11 are supplied to detecting portion 13 to detect only the data based on the output signal from reference signal outputting portion 19.
Serial/parallel shift register 14 shifts the data from detecting portion 14 from the serial state into the parallel state.
Reference value outputting portion 15 outputs the reference value of the commanding data corresponding to the leftward and rightward rotations and the turning on and off to comparing portion 15. Comparing portion 15 compares the output signals from serial/parallel shift register 14 with the output signals from reference value outputting portion 15 to output the leftward and rightward rotation signals and the turning on and off signals.
Motor control signal outputting portion 17 sends operation control control signals of motor M to motor operating portion 18 according to the rotating direction signals of television receiver 3 from rotation direction detecting portion 19 and the output signals from comparing portion 15. motor operating portion 18 operates motor M according to the output signals from motor M control signal outputting portion 17.
Fig.s is a detailed circuit illustrating motor control signal outputting portion 17 and rotation direction detecting portion 19. Resistors 191 and 192 are connected in serial to power source B+. Two connecting points between resistors 191 and 192 each has switches 7 and 6 connected to clock port CK1 of flipflop 193 and clock port CK2 of flipflop 194. Flipflops 193 and 194 have input ports D1 and D2 feed-backed to their output ports Q1 and Q2, respectively. Flipflops 193 and 194 outputs leftward rotation detecting signal LDS and rightward rotation detecting signal RDS from their output ports Q1 and Q2, respectively. With it, rotation direction detecting portion 19 is established.
On-off signals ONF from comparing portion 16 are sent in common to any one of input ports of AND gates 1,1 and 172 while being supplied in common through inverter 173 to any one of input ports of AND gates 174 and 175. Leftward and rightward rotation signals from comparing portion 16 are respectively applied to other input ports of AND gates 171 and 172. The other input ports of AND gates 174 and 175 are respectively connected to receive any one of leftward rotation detecting signals LDS and rightward rotation detecting signals RDS.The output ports of AND gates 171 and 1,2 are respectively connected through switches 8 and 9 for detecting the completion of rightward and leftard rotations to any one of input ports of OR gates 176 and 177, while the other input ports of AND gates 176 and 177 are respectively coupled to the output ports of AND gates 174 and 175. OR gates 176 and 177 respectively outputs rightward rotation operating control signals
ROD and leftward rotation operating control signals LOD to motor operating portion 18. As to it, motor control signal outputting portion 17 is completed.
Comparing portion 16 outputs the high level signal of on-off signals ONF when the power turning on of television receiver 3 is ordered by users. While comparing portion 16 outputs the low level signal of on-off signals ONF when the power turning off of television receiver 3 is ordered b users. In other words, comparing portion 16 generates any one of rightward rotation signals RRO and leftward rotation signals LOD according to users' leftward and rightward orders.
According to the invention, transmitting portion 10 is operated by users to issue the orders corresponding to the power source turning on-off and the rotating directions of television receiver 3. At that time, transmitting portion 10 applies the commanding data signals corresponding to the power source turning on-off and the rotation of television receiver 3 to ultraviolet light emitting diode 101. Ultraviolet light emitting diode 101 is coupled with light receiving diode 102 to form a photocoupler.
Light receiving diode 102 is contained in amplifying/filtering portion 11. Amplifying/filtering portion 11 amplifies/filters the light receiving signals of light receiving diode 102 to output the data corresponding to the power source turning on-off and the rotation of television receiver 3. This data is inputted into data detecting portion 13.
Reference signal generating portion 12 generates the reference signal of 100 KHz to apply it to data detecting portion 13. Data detecting portion 13 exactly detects the data of the onoff and rotating commands from amplifying/filtering portion 11 based on the reference signals of reference signal generating portion 12. This data is converted into parallel data from serial data at serial/parallel shift register 14 to apply them to comparing portion 16.
On the other hand, reference value outputting portion 15 sends the data of the on-off and rotating commands to comparing portion 16. Comparing portion 16 compares the on-off and rotating commands with the output signals of serial/parallel shift register 14 to discriminate the users' orders as well as to output the discriminated signals.
Herein, comparing portion 16 applies rightward rotation signals PRO having the high level through rightward rotation completion detecting switch 8 and OR gate 1,6 to motor operating portion 18, when television receiver 3 is turned on. The operating control signal ROD from OR gate 176 forces motor operating portion 18 to rotate motor M rightwardly.
As motor M is rotated rightwardly, supporting bar 5 is rotated rightwardly with television receiver 3 being positioned on rotating portion 2. Then, when the right end of supporting bar presses rightward rotation detecting switch 6, the divided voltage of connecting points between resistors 191 and 192 is applied through rightward rotation detecting switch 6 to clock port CK2 of flipflop 194. Flipflop 194 outputs rightward rotation detecting signal RDS of the high level at one output port Q2 to
AND gate 175, but AND gate 175 receives the lower level signal inverted from on-off signal ONF of the high level at inverter 173 to be maintained in the disable state.
Continuously, supporting bar 5 is rotated rightwardly in maximum to presse rightward rotation completion detecting switch 8, so that rightward rotation completion detecting switch 8 may be opened. With television receiver 3 being rotated rightwardly in maximum, comparing portion 16 sends the rightward rotation signals RRO of the high level altogether with AND gate 172, but the high level signals are blocked at rightward rotation completion detecting switch 8 to force motor operating portion 18 to stop the further rightward rotation of motor M.
On the contrary, when users order the leftward rotation of television receiver 3, comparing portion 16 generates leftward rotation signals LRO of the high level to apply them to AND gate 12, so that AND gate 172 may output the high level signals. The high level signals considered to be rightward rotation control signals LOD are transferred through leftward rotation completion detecting switch 9 and OR gate 177 to motor operating portion 13.
Motor operating portion 18 operates motor M to be rotated leftwardly. Motor A rotates supporting bar 5 leftwardly with television receiver 3 being positioned on rotating portion 2.
As supporting bar 5 is rotated leftwardly, its end presses leftward rotation detecting switch 7, and flipflop 193 outputs leftward rotation detecting signals LDS of the high level at one output port Q1 to AND gate 174, but AND gate 174 receives the low level signals inverted at inverter 173 at the other input port to be maintained in the disable state, thereby outputting the low level signals.
With television receiver 3 being rotated leftwardly in maximum, supporting bar 5 makes leftward rotation detecting switch 9 opened. At that time, nevertheless users' leftward rotation orders motor operating portion 18 does not receive leftward rotation control signals LOD of the high level to be not able to operate motor A, furthermore.
That is to say, transmitting portion 10 is operated by users to order the leftward and rightward rotation of television receiver 3. Comparing portion 16 outputs rightward rotation signals RRO and leftwardly rotation signals LRO, selectively, to apply any one of rightward rotation control signals ROD and leftward rotation control signals LOD to motor operating portion 18. Motor operating portion 18 rotates motor M, rightwardly or leftwardly, to move television receiver 3 to users' desirable angle, while flipflops 194 and 193 output rihtward rotation detecting signals RDS and leftward rotation detecting signals
LOD, respectively.
On the other hand, when television receiver 3 is rotated rightwardly or leftwardly, and users order the power source turning off of television receiver 3, comparing portion 16 applies on-off signals ONF of the low level to AND gate 171 or 172. At that time, any one of AND gates 171 and 172 continues to output the low level signals, while inverter 173 receiving on-off signals ONF of the low level inverts the low level signals into the high level signals to input them into the corresponding gate of AND gates 174 and 175, thereby operating the corresponding gate.
Herein, in case that television receiver 3 is rotated rightwardly, and flipflop 194 outputs rightward rotation detecting signals RDS of the high level to AND gate 17, AND gate 175 sends the high level signals to OR gate 177. OR gate 177 apply leftward rotation control signals LOD to motor operating portion 18, so that motor operating portion 18 may rotate motor M, leftwardly, to return television receiver 3 to the original position facing to the front.
When the return of television receiver 3 is completed to be turned toward the front, and supporting bar 5 presses rightward rotation detecting switch 6, flipflop 194 inputs the low level signals at its output port Q1 to AND gate 175. And gate 175 sends the low level signals to OR gate 177. OR gate 177 inputs the low level signals into motor operating portion 18, so that the leftward rotation of motor M may be stopped.
When television receiver 3 is rotated lefcwardly, and flipflop 193 generates leftward rotation detecting signals LDS of the high level, motor operating portion 18 receives rightward rotation control signals ROD of the high level to rotate motor M rightwardly, thereby returning television receiver 3 to the original position facing to the front. In case that the return of television receiver 3 is completed by being rotated toward the front, leftward rotation detecting switch 7 is closed. Flipflop 193 outputs the low level signals at output port Q1 to block the transferring of rightward rotation control signals ROD to motor operating portion 18, so that the rightward rotation of motor M may be stopped.
Herein, it is noted that an embodiment of the invention can be constructed using a remote controller. Also, the invention will be provided with at least one power source switches cooperated with a rightward rotation commanding switch and a leftward rotation commanding switch and at least one switches connected with a power switch of a television receiver, so that it may issue rightward rotation control signals RRO and leftward rotation control signals LOD to control the rotation of a rotating portion based on the connection of at least to power source switches.
As explained above, it is known that the invention easily rotates a safe seat plate having a television receiver positioned thereon, so that the audition of a television receiver may be comfortably given.
