Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 and 2 show an example of a portable wireless device including a channel selection control device according to an embodiment of the present invention. The wireless device 1 includes a communication mechanism in which a casing 2 has a multi-channel function. And a microphone, a speaker, and the like, and an antenna 3 and a volume control knob 4 are provided on the upper wall 2a of the casing 2.

The multi-channel function is configured by a manually switchable rotary switch (not shown) built in the casing 2, and the rotary switch is rotated forward and backward between a start end S and a terminal end E. In order toward the normal rotation direction F, a leading channel (first channel No. 1) and a plurality of intermediate channels (in the example shown, channels No. 2 to No. 13) corresponding to a predetermined turning angle of the turning shaft 5; A number of channels including the end channel (channel No. 14 in the illustrated example) are provided.

Accordingly, in the example shown in the figure, the rotation shaft 5 has a start channel selection position CS (first first position) where the position of the start end S for starting rotation in the forward rotation direction F selects the first channel (channel No. 1). An intermediate channel selection position CM (first position C1) for selecting an intermediate channel (channel No2 to No13) at each predetermined rotation angle (in the illustrated example, every 20 degrees) in the forward rotation direction F. The second selection position C2 to the thirteenth selection position C13) are configured, and the position of the end E is set as the end channel selection position CE (the 14th selection position C14) for selecting the end channel (channel No. 14). Yes. However, the number of channels shown is merely an example and does not limit the present invention, and the channel selection position of the rotary shaft 5 does not necessarily include the positions of the start end S and end E as the start channel selection position CS and It is not necessary to match the end channel selection position CE.

As shown in FIG. 2, the rotating shaft 5 includes a protruding shaft portion 5a protruding from the upper wall portion 2a of the casing 2, and a knob 6 is provided on the protruding shaft portion 5a. The knob 6 is crowned by the protruding shaft portion 5a and fixed to the fitting portion 7 with a screw 6a, and is disposed at a predetermined upper position of the upper wall portion 2a of the casing 2 (see FIG. 5). 6 and the rotating shaft 5 are integrally rotated.

(Seat and control body and positioning means)
A seat portion 8 is provided on the upper wall portion 2a of the casing 2 so as to be located on the circumference of the projecting shaft portion 5a, and is rotatable between the seat portion 8 and the knob 6 around the projecting shaft portion 5a. A control body 9 slidable along the protruding shaft portion 5a is provided, and a control body is provided by interposing an elastic urging means 10 comprising a coil spring between the control body 9 and the knob 6. 9 is configured to urge and urge toward the seat portion 8.

As shown in FIGS. 3, 6 (A) and 7 (A), the seat portion 8 and the control body 9 are positioned on the concentric circumference of the rotating shaft 5, and are provided with a recess 11 that is detachable from each other. The convex portion 12 is provided, and the control body 9 is selectively set to the rest position P and the control position Q in the rotational direction by selectively locking the concave portion 11 and the convex portion 12 with respect to the rotational position of the control body 9. It is configured to be positioned and fixed to.

In the case of the illustrated embodiment, the seat portion 8 has a disk-shaped seat surface 13 raised on the circumference, and an annular wall 14 is provided so as to surround the periphery of the seat surface 13. The concave portion 11 is formed in the peripheral portion.

The control body 9 is formed in a disk shape having a central hole 15 extending therethrough, and a substantially annular leg seat 16 is provided around the bottom, and the convex portion 12 is provided so as to project from the outer periphery of the leg seat 16.

Therefore, by inserting the protruding shaft portion 5a through the center hole 9a, when the leg seat 16 of the control body 9 is placed on the seat surface 13, the concave portion 11 and the convex portion 12 are locked, and the control body 9 is fixed. Locks in a non-rotatable position at the position.

In the case of the illustrated embodiment, a large number of concave portions 11 are arranged at equal intervals in the circumferential direction, and a pair of convex portions 12, 12 that are simultaneously fitted into a pair of adjacent concave portions 11, 11 are provided. The intervals between the multiple recesses 11 are configured to correspond to the intervals between the channel selection positions C1 to C14 described above (equal intervals of 20 degrees in the figure). However, contrary to the configuration of the illustrated embodiment, a large number of convex portions 12 may be arranged at equal intervals in the circumferential direction, and at least one concave portion 11 may be fitted to the convex portion 12. .

In the case of the configuration shown in FIG. 6A, the plurality of recesses 11 are provided with recesses 11a in the channel region arranged in a ring gear shape corresponding to the channel selection positions C1 to C14, the first channel selection position C1, and the end. A recess 11b outside the channel area formed between the channel selection positions C14 is included, and the position where the projection 12 is fitted to the recess 11b outside the channel area is the rest position of the control body 9 with respect to the rotation direction of the control body 9. P (see FIG. 6 (A)), and the position where the convex portion 12 is fitted in the concave portion selected from the concave portions 11a in the channel region is the control position Q (see FIG. 7 (A)) of the control body 9.

As shown in FIG. 5 (A), the control body 9 urged and urged by the urging and urging means 10 has an upper surface height in a state where the seat leg 16 is placed on the seat surface 13 of the seat portion 8. The lower end of the convex portion 12 indicated by the height position P <b> 1 is lower than the concave portion 11 having a level L <b> 1, and the convex portion 12 is fitted into the concave portion 11. In this state, a gap G is formed between the control body 9 and the knob 6. The gap G enables the control body 9 to be lifted, and when the lift is lifted, the convex portion 12 is detached from the concave portion 11. It is configured as follows. Accordingly, when the user picks up the control body 9 with the fingertip and lifts it against the bullet urging means 10, the convex portion 12 rises to the height position P2 as shown in FIG. The control body 9 can be rotated. Therefore, by rotating the control body 9, when the rest position P and the control position Q are selected and released from the fingertip after the selection, the control body 9 is lowered by the bullet urging means 10, and the convex portion 12 is moved. It is fixed so as not to rotate by being inserted into the predetermined recess 11.

In the case of the illustrated embodiment, as shown in FIG. 6 (A), the seat portion 8 is provided with a barrier 17 adjacent to the recess 11b outside the channel region, and as shown in FIG. The height level L2 is formed to be higher than the height level L1 of the recess 11. Therefore, when the control body 9 is lifted and rotated as shown in FIG. 5B, the rotation range of the control body 9 is limited by the convex portion 12 coming into contact with the barrier 17, and the limited rotation range. Only forward and backward rotation is possible. In the case of the illustrated example, the control body 9 can be rotated forward and backward with a rotation range between a position where the convex portion 12 is fitted into the concave portion 11a of the first channel selection position C1 and a position where the convex portion is fitted into the concave portion 11b outside the channel region. It is said that. By providing such a barrier 17, when the control body 9 is positioned and fixed at the rest position P, the control body 9 is automatically rotated only by rotating the control body 9 forward until the convex portion 12 contacts the barrier 17. Therefore, it is possible to stop at the rest position P and easily fix the positioning, so that the work is easy.

According to the illustrated embodiment, the control body 9 is moved to the rest position P by the configuration of the concave portion 11 and the convex portion 12 provided between the seat portion 8 and the control body 9 and the configuration enabling the control body 9 to move up and down. "Positioning means" for selectively positioning at the control position Q, "Locking means" for locking the control body 9 to the selected position of the positioning means so as not to rotate, and release of the locking means “Locking release means” is configured.

However, the positioning means, the locking means, and the locking release means of the present invention are not limited to the above, and for example, the control body 9 may be fitted according to each side of the polygon. It is also possible to insert a retractable pin into the selected hole. In short, the control body 9 can be rotated between the rest position P and the control position Q and can be selectively positioned. Any configuration that enables locking and unlocking may be used.

(Control body and knob and regulating means)
As shown in FIG. 4, a first stopper 18 is provided at the upper part of the control body 9, and a second stopper 19 is provided at the lower part of the knob 6. Both stoppers 18 and 19 are arranged on the circumference centering on the rotation shaft 5 and arranged so as to be able to contact each other, thereby constituting a restricting means 20 for restricting the rotation range of the knob 6.

As described above, when the control body 9 is rotated and the rest position P and the control position Q are selected, the first stopper 18 is accompanied and moved in the circumferential direction to be positioned at a predetermined position. On the other hand, the knob 6 rotates the rotation shaft 5 having a rotation range between the starting end S and the terminal end E. The knob 6 accompanies the knob 6 and moves in the circumferential direction. When the stopper 19 comes into contact with the first stopper 18, the rotation is prevented.

As shown in FIG. 6 (A), when the control body 9 is positioned and fixed at the rest position P, the first stopper 18 is positioned at the retracted position V shown in FIG. 6 (B). In this state, as shown in FIGS. 6C and 6D, the second stopper 19 abuts against the first stopper 18 while rotating the knob 6 from the head channel selection position C1 to the tail channel selection position C14. do not do. Therefore, the knob 6 can be rotated in the forward and reverse directions within the rotation range between the first channel selection position C1 and the last channel selection position C14, thereby enabling switching and selection of all channels of the rotary switch. That is, the first stopper 18 is disposed at a position where it does not interfere with the second stopper 19 that moves together with the knob 6 that rotates between the head channel selection position C1 and the tail channel selection position C14.

As shown in FIG. 7A, when the control body 9 is positioned and fixed at the control position Q, for example, as shown in the figure, the convex portion 12 is provided with the concave portion 11a at the position corresponding to the eleventh intermediate channel selection position C11. When selected and inserted, the first stopper 18 is positioned at the restricting position W shown in FIG. In this state, as shown in FIGS. 7C and 7D, when the second stopper 19 rotates the knob 6 in the forward rotation direction F from the leading channel selection position C1, the knob 6 moves to the tenth intermediate position. When it is turned to the channel selection position C10, it comes into contact with the first stopper 18, thereby preventing the knob 6 from further turning. Accordingly, in this case, the knob 6 is not rotatable toward the eleventh and subsequent intermediate channel selection positions C11 to C14. That is, the knob 6 can be rotated forward and backward in a limited rotation range between the first channel selection position C1 and the predetermined intermediate channel selection position C10, and the channel of the rotary switch existing in the rotation range. Enables switching and selection.

In addition to the position shown in the figure, the control position Q of the control body 9 can be selected at any position by fitting the convex portion 12 into a desired concave portion 11a selected from the concave portion 11a in the channel region. For example, when the user wants only three channels from the first channel to the third channel of the rotary switch, the convex portion 12 is inserted into the concave portion 11a at the position corresponding to the fourth intermediate channel selection position C4. You can do it. In this case, the first stopper 18 is positioned at the restriction position W that receives the second stopper 19 when the knob 6 is rotated to the third intermediate channel selection position C3. As a result, the knob 6 can be rotated forward and backward only within a limited rotation range between the first head channel selection position C1 and the third intermediate channel selection position C3, and switching and selection of the three channels can be performed. to enable.

As described above, the control of the number of channels by the restricting means 20 includes the selected control position Q of the control body 9, the corresponding restricting position W of the first stopper 18, the number of channels of the rotary switch, and the rotating shaft 5. Channel switching angle and the correlation between conditions such as the movement range of the second stopper 19 provided on the knob 6 that rotates forward and backward between the first channel selection position CS and the last channel selection position CE. It should be understood that the present invention is not limited to the illustrated embodiments.

For example, the relationship between the concave portion 11 and the barrier 17 provided in the seat portion 8 and the convex portion 12 and the first stopper 18 provided in the control body 9 is as follows with respect to the channel selection positions C1 to C14 of the rotating shaft 5 illustrated. The position may be different in the circumferential direction. In short, the rest position P and the control position Q of the control body 9 can be selected and the control position Q can be selected according to a plurality of channels. If it is good. In this case, in the illustrated embodiment, the recesses 11a in the channel area are arranged up to the first channel selection position C1, but the minimum number of channels that can be limited is limited to, for example, 3 channels or 5 channels in advance ( That is, in the case of providing a product that cannot be limited to the number of channels less than that, it is not necessary to provide the concave portion 11a that is unnecessary.

Further, the relationship between the first stopper 18 and the second stopper 19 is basically configured such that when the knob 6 is rotated forward from the head channel selection position CS, the rotation is prevented at the desired intermediate channel selection position CM. If it is what you did. Therefore, in the case of the illustrated example, the first stopper 18 and the second stopper 19 are formed thick with respect to the rotation direction of the knob 6, but an arbitrary configuration such as a thin plate shape may be employed.
