Definitions

  • a multi-control mechanism comprising in combination separate rotary control means having coaxial rotary adjusting shafts respectively and a switch means related to one of said rotary adjusting shafts which is axially slidable, said switch means being adapted to be operable in response to the sliding motion thereof.
  • the above said axially slidable rotary adjusting shaft has a clearance means and a universal joint means.
  • This invention relates to a multi-control mechanism, and more particularly to a tuning shaft mechanism in the case where an operating shaft is provided with a push-button switch in addition to a volume control or a tone controller, etc.
  • a radio receiver to be mounted on a car is provided with a knob for operation of a power source switch, a volume control or a hand-operated tuning shaft in addition to a group of push buttons for tuning.
  • the operating shaft is in many cases made dual and the operating knobs are usually disposed in combinations such as mainly the tuning shaft and the tone adjusting knob, the power source switch and the volume adjusting knob, and so forth.
  • This invention is to eliminate such a defective point as mentioned above by interlocking with a dual operating shaft a single shaft which is coupled to a tuner or the like so as to make three kinds of control operations controllable by a single knob provided at one place.
  • a first rotary adjust means which may be a volume control device comprising a rotary, variable resistor has an adjusting shaft which is coaxial with that of a second means which is axially and rotatably movable.
  • the second means may be a switch operated so as to be adapted to occupy a plurality of angular positions after for all of its axial positions.
  • a third rotary adjusting means which may be a tuner of a car radio set, is connected through its adjusting shaft to the second means shaft to be operated in response to the rotation of the latter.
  • a clearance means is provided between this second means shaft and the third means shaft.
  • at least one angle adjusting means consisting of a universal joint may be provided between said second means shaft and said third means shaft.
  • FIG. 1 is a perspective view showing a tuning shaft mechanism in disassembled form of this invention.
  • FIG. 2 is a perspective view showing the essential part in enlarged form of said mechanism.
  • reference numeral 1 is a mounting plate in which, for example, a rectangular mounting hole 1 is provided, and, in said mounting hole 1, for example, a mounting shaft 2 of a volume control 2 is inserted and fixed by a lock nut 2", said mounting shaft 2' being constructed'in dual shaft form.
  • a rotary shaft 3 of a volume control 2 is provided, and, inside said shaft 3, there is provided an operating shaft 4 for a push-button switch 5.
  • This switch 5 is formed integrally with the volume control 2 and is coupled to said operating shaft 4, so that the operating shaft 4 is pressed to slide axially to thereby operate the push-button switch 5.
  • the operating shaft 4 is mounted rotatably with respect to said rotary shaft 3 and is passed therethrough so that the terminal portion 4' thereof is positioned at the rear of the push-button switch 5 and coupled to a mounting hole 6' of a channel-shaped metal member 6.
  • This channel-shaped metal member 6 has bent sides 7 and 8 which are provided with slots 7 and 8 respectively. In these slots 7 and 8, aligned arms 9-9 of a coupling member 9" are inserted.
  • the coupling member 9" has aligned arms 10-10 extending transversely to arms 9-9 engaged in slots 12 and 13 provided in bent said 12' and 13' respectively of a separately provided channel-like metal member 1 1. This channel-like meta!
  • the channel-like metal member 11 and the channel-shaped metal member 6 are coupled by the arms 99 and l0l0 to form what is called a universal joint.
  • a shaft 14 which is further coupled to, as one example, a tuning operating shaft 16' of a tuner 16 through a coupling joint 15 which permits pivoting or folding of shaft 14 relative to the fixed shaft 16 in a horizontal direction as viewed in FIG. 1. Accordingly, shafts 2, 4 and 14 can be moved bodily as a unit in a plane containing the axes of all of the shafts because of the coupling joint 15 when unit 2" is loosened to permit such movement along the mounting hole 1.
  • the push-button switch 5 is operated by pressing the operating shaft 4 which is interlocked with said push-button switch 5.
  • This pushbutton switch 5 is constructed so that, when the operating shaft 4 is pressed, the switch mechanism is closed. Then, when the shaft 4 is released, the shaft 4 alone returns to its original condition, the closed-circuit condition of the switch mechanism being maintained as it is, and, when the shaft 4 is pressed again, the switch mechanism is converted to an open-circuit condition.
  • the operating shaft 4 when the operating shaft 4 is pressed, it slides axially inside the shaft 3 to change-over the pushbutton switch 5 and, at the same time, to move axially the channel-shaped metal member 6 fixed to the tenninal portion 4 of said shaft 4.
  • the arms 99 of the coupling member 9" are engaged in the slots 7 and 8 of said channel-shaped metal member 6 and the other arms 10l0 thereof are engaged in the slots 12 and 13 of the channel-like metal member 11, it follows that, with the movement of the channelshaped metal member 6, said coupling member arms 10-10 along the slots 12 and 13 of the channel-like metal member 11, the pressing action of the operating shaft 4 not extending to the channel-like metal member 1 1.
  • an axially slidable universal joint is coupled to the terminal of an operating shaft to which the push-button switch is coupled and, further, a rotary operating shaft for a tuner is also coupled to said joint, so that it is possible, with the dual shaft for operation, to effect control of the volume or tone quality and, at the same time, to carry out the operation of the power source switch and the tuner, or the like, that, in the case of an audio apparatus to be mounted on a car that is limited in space of installation, it is possible to utilize the front panel effectively, and that, even in the case where an audio apparatus such as car stereo or the like is provided together with a radio receiver, it is possible to provide change-over switch, etc. operating knobs for that purpose.
  • this invention makes it possible to improve the operation efficiency as compared with conventional one and exhibits very excellent effects in practical use.
  • a first rotary adjusting means having a first adjusting shaft; a second rotary adjusting means having a second adjusting shaft; a coupling joint interconnecting said first adjusting shaft with said second adjusting shaft so said first adjusting shaft can be moved axially in all the different possible rotary positions thereof without moving the second adjusting shaft in a corresponding axial direction
  • said coupling joint comprising a first channel-shaped member secured to said first operating shaft for axial and rotatable movement therewith and having slotted axially extending sides, a coupling member having a first pair of aligned arms engaged within the slots in the sides of said first channel-shaped member so as to be rotatably and axially moved therewith and a second pair of aligned arms extending in a direction transversely to said first pair of aligned arms, and a second channel-shaped member connected to said second adjusting shaft and having axially extending slotted sides which axially slidably receive in slots therein said second pair of aligned arms of said coup
  • a third rotary adjusting means having a third adjusting shaft, said third adjusting shaft being coaxially related with respect to said first adjusting shaft, and a third device constituting a volume control operated by rotation of said third adjusting shaft.
  • tuning unit is coupled to said second adjusting shaft through a joint which pennits said first and second adjusting shafts to be moved bodily together as a unit in a given plane direction containing the axes of the shafts.
