Definitions

  • the present invention relates to a switch adapted to be used as a remote controlling switch for motor-driven rear view mirrors of a motor vehicle and, more particularly, to a switch which has switch elements composed of a pressure-sensitive electrically conductive rubber sheet.
  • Each of a pair of motor-driven rear view mirrors mounted on a door, a fender or the like, of a motor vehicle has two electric motors, etc. in its driving section, said electric motors, etc. being controlled by means of a switch inside the vehicle so as to adjust the direction of inclination, horizontal or vertical, of each mirror.
  • the switch for controlling the motor-driven rear view mirrors is required to have the functions of actuating each of said two electric motors of each mirror independently, and changing the polarity of electric power supply thereto. Also, the switch must be easy to fix in the instrument panel, etc.
  • a switch which, as disclosed in Japanese Utility Model Application No 56-71428 comprises a plurality of stationary contact elements each formed of a pair of printed circuit electrodes arranged around a specific central position on an insulating board, a pressure-sensitive electrically conductive rubber sheet forming switch elements together with said stationary contact elements and laminated on said contact elements, two sets of power source polarity changing switches composed of said switch elements, and operation buttons each having a pressing surface tiltably at said specific central position on said rubber sheet and including a constantly resettable trend for driving each switch element.
  • the button is tiltably operated in a desired direction to operate the corresponding switch element, thereby converting and controlling the angle of the mirror in the predetermined amount in elevational and lateral directions.
  • U.S. Patents Nos. 2,748,205 and 4,249,086, Japanese Utility Model Publication No. 41-7847 and Japanese Patent Laid Open No. 55-32334 disclose switches comprising a plurality of operation buttons or interceptor means.
  • Japanese Patent Laid Open No. 55-32334 discloses a switch wherein a rotary member and the engaging pawls of operation buttons form a means for preventing simultaneous operation of switch elements.
  • this switch has a common operation button arranged for a plurality of switch elements, individually operates the corresponding switch element by tilting one button in the desired direction, and converts and controls the angle of the motor-driven rear view mirror in elevational or lateral direction. Accordingly, the relationship between the elevational and lateral control directions and the operating positions is not sufficiently established, and it does not provide the good operability and good feeling of use.
  • said multi-position electrical switch comprising an insulating board, a plurality of stationary contact elements each formed of a pair of printed circuit electrodes and arranged around a specific central position on said board, a pressure-sensitive electrically conductive rubber sheet arranged on said stationary contact elements, said rubber sheet and contact elements forming switch elements, a plurality of operation buttons disposed on said rubber sheet, said buttons having constantly resettable trend, pressing surfaces for driving said switch elements and an engaging pawl projected toward said specific central position on said board, and a crown-shaped interceptor rotatably arranged at said specific central position and having a sawtoothed cam surface with teeth of a number different from that of said buttons which corresponds to said pawls at the end face thereof, wherein when a button is depreseed so that its pawl is introduced into the deepest part of the valley on the cam surface, said switch element is
  • a housing, 2 a printed board (an insulating board) which operates also as the bottom plate of the housing 1 as shown in Figs. 1 and 2.
  • a switch S 1 forming a switch for changing the polarity of a power supply and another switch S 2 for changing a motor driven rear view mirror.
  • the switch S 1 comprises, for example, six switch elements illustrated by A to F as shown in Fig. 15.
  • Each pair of printed circuit electrodes 3a and 4a to 3f and 4f, serving as stationary contact elements of the switch elements A to F, are printed around a specific central position 7 on the printed board 2 in a pectinated shape.
  • the printed circuit electrodes 3a and 4a to 3f and 4f are disposed to occupy the substantially square area around the specific central position 7 of the printed board 2 as a whole (Fig. 13).
  • This rubber sheet 5 is common to all the stationary contact elements.
  • the pressure-sensitive electrically conductive rubber sheet 5 is made of composite material which contains silicone rubber and metal particles. It is a material which is transferred from insulating state to conductive state in response to the pressure stimulus.
  • the six switch elements A to F are disposed planely on the printed board 2 and these switch elements A to F are connected by printed conductors 6 so as to form two sets of power supply polarity changing switches as connected as required. That is, in Fig. 15, the three switch elements A, B and E form one switch means for vertical adjustment to be described later and the three switch elements C, D and F form the other switch means for horizontal adjustment. The two switch elements E and F are commonly used with the switch for changing the polarity of both power supplies.
  • the arrangement of the switch elements Ato F on the printed board 2 is illustrated in Fig. 14.
  • Driving mechanism as follows is disposed over said switch elements A to F formed as described above.
  • a supporting plate. 21 as shown in Fig. 4 is disposed on the rubber sheet 5, and is fixed at its peripheral to the housing 1.
  • the supporting plate 21 is provided at its portions corresponding to the positions of said switch elements A to F with openings 21a into which pressing surfaces (described later) are loosely inserted.
  • the housing 1 is provided at its portion corresponding to said specific central position 7 on the inside with a projecting axial pin leas shown in Fig. 3, said housing 1 further having four trapezoidal openings 1a to 1d disposed with the axial pin 1e as the center of symmetry.
  • Operation buttons 22 to 25 are respectively inserted into the trapezoidal openings la to 1 d so that each of the operation buttons can be pushed in and automatically returns to its original position.
  • buttons 22 to 25 is provided on its side facing the rubber sheet (5) with two pressing surfaces 22a, 22b which project slightly as designated representatively of the buttons 22 in Figs. 5 to 7.
  • One pressing surface 22a of the two pressing surfaces corresponds to the switch element A, while the other pressing surface 22b corresponds to the switch element F.
  • the operation button 22 is provided with an engagement pawl 22c engaged toward the axial pin 1e, having a triangular section with its vertex facing downward (toward the rubber sheet side).
  • the button 22 further has a spring hole 22d at the intermediate between the two pressing surfaces 22a and 22b.
  • a helical spring 26 is disposed within the spring hole 22d and is compressed between the operation button 22 and the supporting plate 21 so as to provide the operation button 22 a tendency to return to its original position.
  • the pressing surfaces 22a and 22b of the operation button 22 are partially inserted into the openings 21a of the supporting plates 21 so that the pressing surfaces 22a and 22b are surely guided by the openings 21a when the operation button 22 is pushed.
  • the construction and arrangement of the other operation buttons 23 to 25 are the same as mentioned above.
  • the operation button 23 corresponds to the switch elements B and E.
  • the operation button 24 corresponds to the switch elements F and C.
  • the operation button 25 corresponds to the switch elements D and E.
  • the operation button 25 corresponds to the switch elements D and E. In this way, each of the operation buttons 22 to 25 corresponds to two switch elements.
  • a crown-shaped interceptor 27 having a sawtoothed cam surface 27a corresponding to the engagement pawls 22cto 25c is rotatably attached to the axial pin 1e in the specific central position 7.
  • the sawtoothed cam surface 27a has teeth, the number of which is different from the number (four) of the operation buttons 22 to 25, that is, the number (four) of the engagement pawls 22cto 25c.
  • the sectional crests forming the respective teeth are not formed at both sides in a symmetrical shape at the edge (crest part), but the crests formed in the range of 72° of the opening angle planely as shown in Fig.
  • the number of the teeth of the sawtoothed cam surface 27a is five in the illustrated example, but it is not limited thereto and may be three, seven, nine or any other number provided that the difference between the number of the teeth and the number of the operation button is an odd number.
  • the switch S 2 is for selectively connecting the above-mentioned switch S 1 with either the right-hand mirror R or the left-hand mirror L and is contructed as follows:
  • the switch S 2 comprises two circuits and six contacts. Contact patterns /, m and 14 a to 14d corresponding to the six contacts, are printed near one end (upper portion in Fig. 13) of the board 2.
  • a slide block 15, slidable right and left in Fig. 11 or 12, is disposed over the contact patterns /, m and 14a to 14d.
  • the slide block 15 is provided with movable contacts 16a and 16b corresponding to the contact patterns l, m and 14a to 14d.
  • a pair of push buttons 17a and 17b respectively corresponding to the right-hand mirror R and the left-hand mirror L are disposed on both sides of the slide block 15 in the direction of its slide.
  • the driving end of each push button is engaged with each of taper portions 15a and 15b formed on both ends of the slide block 15.
  • Numerals 18a and 18b represent balls for positioning the push buttons 17a and 17b.
  • Figs. 1 to 15 is a hybrid switch comprising said switch S 1 including the six switch elements A to F and said changeover switch 5 2 ,
  • Numeral 19 in Fig. 2 represents a connector for externally leading the contacts /, m and 14a to 14d in the changeover switch S 2 to the exterior (the mirrors R and L).
  • symbols M 1 , M 2 represent electric motors for horizontally and vertically driving the right-handed mirror R
  • M 3 , M 4 represent electric motors for vertically and horizontally driving the left-handed mirror L.
  • the engagement pawl 22c of the button 22 enters the deepest portion of a concave on the sawtoothed cam surface 27a (See Fig. 10) and the switch elements A and F are closed. Then, the electric motor M 1 rotates in such a direction to change the angle of the right-hand mirror R upward. Even if any of the other operation buttons 23 to 25 is pushed at this time, the engagement pawl 23c to 25c thereof is not allowed to enter the deepest portion of a concave on the sawtoothed cam surface 27a and therefore no other switch elements are closed.
  • the left-handed mirror L is controlled in the same way as described above.
  • buttons are independently arranged around the specific central position as a center, pressing surfaces and engagement pawls for driving the switch elements are provided at the respective buttons, a crown-shaped interceptor formed with a sawtoothed cam surface made of teeth of the number different from the number of the buttons is rotatably arranged at the specific central position corresponding to the engagement pawls, the buttons are pressed to operate the switch element when the pawl enters the deepest part of the concave on the cam surface, and the switch element is exlusively operated. Therefore, when this is applied as a switch for controlling the motor driven rear view mirror of a vehicle, the control object such as vertical and horizontal controls of the mirror can be clearly corresponded by 1:1 to the buttons. Consequently, the operability and using feeling can be remarkably improved. Since the outer profile can be formed in a flat, thin and small shape, the switch can be readily mounted in a relatively small space such as in an instrument panel of a vehicle.
