The parallel movement within 3 is regulated.

  Note that an interphone monitor speaker is built in substantially the center of the flat surface portion 21, and an opening 21 c for sending sound from the monitor speaker to the outside is formed.

Further, in the cradle 20, the concave portion 22 is accommodated in the concave portion 22 from the side surface of the concave portion 22 on the flat surface portion 21 side (the side closer to the grip portion 12 of the handset 10 attached to the cradle 20). An engaging portion 24 for locking the earpiece portion 22 protrudes (see FIG. 2).

  The engaging portion 24 protrudes into the recess 22 by the elastic force of the spring 26 (see FIG. 3) biased in the protruding direction. When a force stronger than the urging force of the spring 26 is applied to the engaging portion 24 in the direction opposite to the protruding direction, the engaging portion 24 is configured to retreat in the direction opposite to the protruding direction. Thus, the engaging part 24 is configured to be able to advance and retract with respect to the recess. Similarly to the recess 22, an engagement portion 24 is provided for the recess 23.

In the present embodiment, the engaging portion 24 is housed in the holder 25 and is configured as a component (denoted as “engaging portion unit”) that is detachable from the cradle 20. FIG. 3A is a view showing the front surface of the engaging portion 24 accommodated in the holder 25 with a part of the holder 25 cut away. FIG.
FIG. 5B is a view showing the left side surface of the engaging portion 24 accommodated in the holder 25 with a part of the holder 25 cut away. FIG. 3C is a diagram illustrating the mounting of the engaging portion 24 accommodated in the holder 25 to the cradle 20.

  As shown in FIGS. 3A and 3B, the engaging portion 24 is accommodated in the holder 25 by inserting the rear end side thereof from an opening 25 a provided on the plane side of the holder 25. The rear end portion of the engaging portion 24 is attached to a spring (coil spring) 26 built in the holder 25.

  The spring 26 has an urging force in the extending direction and acts to push the engaging portion 24 out of the holder 25. However, locking pieces 24 a are formed on both side surfaces of the engaging portion 25, and stoppers 25 b that are in contact with the locking pieces 24 a are formed on the inner side surfaces of the holder 25. When each locking piece 24a comes into contact with the stopper 25b, the extension of the spring 26 is restricted, and the amount of protrusion (protrusion) of the engaging portion 24 from the holder 25 is restricted.

  The distal end portion of the engaging portion 24 is configured to protrude (protrude) out of the holder 25 in a contact state between each locking piece 24a and each stopper 25b. The front end of the engaging portion 24 is formed in a mountain shape including a flat surface 24 b formed on the front side of the engaging portion 24 and a flat surface 24 c formed on the back side of the engaging portion 25. Here, the angle formed by the plane 24b and the plane 24c is about 90 degrees. However, the angle formed by the planes 24b and 24c may be an acute angle.

  When a force stronger than the urging force is applied to the distal end portion of the engaging portion 24 in the direction opposite to the urging direction of the spring 26, the engaging portion 24 moves backward into the holder 24, and the distal end portion of the engaging portion 24. Is accommodated in the holder 25 to some extent.

  Further, continuous fitting grooves 25 c are formed on both side surfaces and the bottom surface of the holder 25. As shown in FIG. 3C, a notch 21a continuous with the recess 22 is formed at the boundary between the flat portion 21 and the recess 22 of the cradle 20, and the notch 21a includes A fitting piece 21b corresponding to the fitting groove 25c is formed.

  When the holder 25 is mounted on the cradle 20, the bottom surface of the holder 25 is slid from the concave portion 22 side to the flat portion 21 side toward the notch portion 21a, and the fitting grooves 25c on both side surfaces of the holder 25 are formed. It fits with the fitting piece 21b. Then, the holder 25 is pushed into the notch 21a until the fitting groove 25c on the bottom surface of the holder 25 is fitted with the fitting piece 21b.

  In this way, the holder 25 is mounted on the cradle 20, and the distal end portion of the engaging portion 25 protrudes toward the concave portion 22 (a state in which the holder 25 can advance and retract relative to the concave portion 22). At this time, the flat surface 24b of the front end portion is directed upward (opening side of the concave portion 22), and the flat surface 24c is directed downward (bottom surface side of the concave portion 22) (see FIG. 2). When removing the holder 25, the holder 25 can be easily removed by sliding the holder 25 toward the recess 22 side. With such a configuration, the engaging unit can be easily detached and replaced.

As shown in FIG. 1, the engaging portion 24 accommodated in the holder 25 is provided not only for the concave portion 22 but also for the concave portion 23 (hereinafter referred to as the engaging portion 24 provided for the concave portion 22. In this case, it is expressed as “engagement portion 24A”, and when referring to the engagement portion 24 provided for the recess 23, it is expressed as “engagement portion 24B”). The configuration related to the engaging portion 24B provided to the recess 23 is the same as the configuration related to the engaging portion 24A.

That is, an engagement unit having the same configuration as that applied to the recess 22 is prepared for the recess 23. The flat portion 21 has a cutout portion 21 a and a fitting piece 21 b formed on the concave portion 22 side (a cutout portion and a fitting piece similar to those in FIG. 3C) between the concave portion 23 and the flat portion 21. Then, the engaging unit is mounted in the same manner in the notch 21a with respect to the recess 23. At this time, the protruding direction of the engaging portion 24A mounted to the recess 22 and the recess The direction of protrusion of the engaging portion 24 </ b> B attached to 23 is in the opposite direction.

Returning to FIG. 1, the outer peripheral surface (engagement portion 2) of the earpiece portion 13 of the handset 10 near the grip portion 12.
An engagement recess 17 that engages with the engagement portion 24A is formed at a position corresponding to 4A. On the other hand, an engagement recess 18 that engages with the engagement portion 24B is formed on the outer peripheral surface (position corresponding to the engagement portion 24B) of the transmitter / receiver 10 on the side close to the grip portion 12. Yes.

  Each of the engagement recesses 17 and 18 has an internal space that accommodates the distal end portion (mountain shape) of the engagement portion 24 as shown in FIG. 4 as an example of the configuration on the earpiece 13 side. In a state where the lower surface 13a (14a) of the earpiece part 13 (speaker part 14) is in contact with the bottom surface 22a (23a) of the concave part 22 (23), it is formed at a position for accommodating the tip of the engaging part 24 ing.

Each of the engagement recesses 17 and 18 has an opening having a length that is slightly longer than the length in the width direction and the length in the thickness direction of the engagement portion 24. Further, each of the engagement recesses 17 and 18 is a tip portion of the engagement portion 24 accommodated therein in a state where the earpiece 13 and the mouthpiece 14 are accommodated in the corresponding recesses 22 and 23, respectively. And an inner wall surface 17a (18a) that can be flush with the flat surface 24c (the flat surface on the bottom surface side of the recess).

  With the configuration described above, the operation when the handset 10 is placed (attached) on the cradle 20 and when the handset 10 is removed (detached) from the cradle 20 is as follows.

When the handset 10 is mounted on the cradle 20, the earpiece portion is formed with the lower surface 13 a of the earpiece portion 13 and the lower surface 14 a of the mouthpiece portion facing the bottom surfaces 22 a, 23 a of the concave portions 22, 23. 13 and the mouthpiece 14 are moved toward the corresponding bottom surfaces 22a and 23a so that the recesses 22 and 23 are accommodated in the recesses 22 and 23, respectively.

Such a direction that is substantially orthogonal to the advancing and retreating direction of the engaging portion 24 and the earpiece 13 and the mouthpiece 14 are directed toward the bottom surface of the recess (from the upper surface (plane) to the lower surface (back surface) of the cradle 20. Direction) is the mounting direction of the handset 10 with respect to the cradle 20.

  In the process of moving the earpiece 13 and the mouthpiece 14 in the mounting direction, the outer edges of the earpiece 13 and the lower surface 13a of the mouthpiece 14 on the side close to the grip portion 12 correspond to the corresponding portions. It comes into contact with the front end portion (plane 24b) of the joint portion 24.

  Here, the flat surface 24b is a slope inclined in the mounting direction. For this reason, the engaging portion 24 retreats into the holder 25 against the urging force of the spring 26 so as to slide on the outer edge portion with which the flat surface 24 b is in contact. And the front-end | tip of the engaging part 24 is guided to the corresponding engagement recessed part 17 (18), contacting the outer peripheral surface of the earpiece part 13 (speech mouth part 14).

Thereafter, when the lower surfaces 13a, 14a come into contact with the bottom surfaces 22a, 23a, the engaging portions 24A, 2
Engaging recesses 17 and 18 appear in the protruding direction of 4B. As a result, the tips of the engaging portions 24A and 24B protrude (inserted) into the engaging recesses 17 and 18, respectively. The flat surfaces 24c of the engagement portions 24A and 24B are in contact with the inner wall surfaces 17a and 18a of the engagement recesses 17 and 18, respectively.

Through such an action, the engagement portions 24A and 24B engage with the engagement recesses 17 and 18, respectively. As a result, the handset 10 is locked to the cradle 20. Each engaging portion 24A,
24B functions as a lock lever (stopper) that restricts the movement of the handset 10 in the direction opposite to the mounting direction (that is, the direction of separation). Even if the handset 10 vibrates due to movement of the moving body, the cradle 24B The transmitter / receiver 10 is prevented from falling off the cradle 20 regardless of the installation state of 20 (horizontal placement, diagonal placement, vertical placement).

  When the handset 10 is mounted, the flat surface 24c of the engaging portion 24A and the inner wall surface 17a are in contact with each other. As a result, the earpiece portion 13 is sandwiched between the flat surface 24c and the bottom surface 22a. Therefore, even if vibration occurs in the up-down direction of the cradle 20 (detachment direction: left-right direction of the paper surface of FIG. 4), the earpiece 13 is prevented from vibrating in that direction. Similarly, when the flat surface 24c of the engaging portion 24B and the inner wall surface 18a are in contact with each other, the mouthpiece portion 14 is sandwiched between the flat surface 24c and the bottom surface 23a. Therefore, even if vibration occurs in the vertical direction (detachment direction) of the cradle 20, the mouthpiece 13 is prevented from vibrating in that direction. Further, even if strong vibration is generated in the direction in which the handset 10 is attached / detached, this vibration is absorbed by the engagement portion 24A and the engagement portion 24B moving back and forth to some extent.

In addition, the handset 10 of the earpiece 13 and the mouthpiece 14 accommodated in the recesses 22 and 23 is provided.
The sliding movement in the short direction (the left-right direction in FIG. 1) is regulated by contact between the side surfaces of the engaging portions 24A and 24B and the corresponding inner surface of the engaging recess 17 or 18. Further, the slide movement of the earpiece 13 and the mouthpiece 14 accommodated in the recesses 22 and 23 in the longitudinal direction of the handset 10 (vertical direction in the drawing in FIG. 1) The mouth portion 14 is regulated by contacting the holder 25 with an inner peripheral surface orthogonal to the longitudinal direction of the transmitter / receiver 10 (the cradle 20) of the concave portions 22 and 23.

  With the configuration as described above, the handset 10 attached to the cradle 20 is not affected by the vibration associated with the movement of the moving body, regardless of the installation state of the cradle 20 (horizontal placement, diagonal placement, vertical placement). It is further prevented from falling off 20.

When removing the handset 10 from the cradle 20, the handset 10 is moved in the direction opposite to the mounting direction (the direction of detachment). Here, the handset 10 is slid in the front direction (upward on the paper surface in FIG. 1) or the rear surface (downward on the paper surface in FIG. 1) of the cradle 20 so that the engagement portion and the engagement recess are engaged. Even when the combined state is to be released, the movement to the state where the engaged state is released is restricted by contacting the inner peripheral surface of the recess provided in the moving direction or the holder 25.

  Even if the engagement state by one engagement portion is released due to the sliding movement in either the front direction or the back direction, the engagement state by the other engagement portion is not released. . For example, even if the engagement state between the engagement portion 24A and the engagement recess 17 is released by sliding the handset 10 mounted on the cradle 20 in the front direction, the engagement portion 24B is engaged. The engaged state with the joint recess 18 is not released.

For this reason, in order to release the engaged state by the engaging portions 24A and 24B, the lower surfaces 13a, 1
The direction in which 4a is separated from the bottom surfaces 22a, 23a of the recesses 22, 23, that is, the direction of separation (FIG. 4).
It is required to move to (see).

Here, the flat surface 24c at the tip of each engaging portion 24A, 24B is a slope inclined in the disengagement direction. For this reason, each engaging part 24A, 24B does not restrict | limit the movement to the separation direction of the earpiece part 13 (speech mouth part 14) in which the plane 24c is engaged, but each receiving part which moves to a separation direction. The mouth portion 13 (the mouthpiece portion 14) is pushed in the retraction direction, and retreats into the holder 25 against the urging force of the spring 26. And each engaging part 24 and earpiece part 13 (speaker part 1
When the contact state with 4) is released, the locked state of the handset 10 is released. Then, each engaging part 24 returns to the original protruding state.

Thus, in the present embodiment, the front end portion of the engaging portion 24 has a flat surface 24c (which may be a substantially flat surface) inclined in a direction away from the bottom surface of the recess. Thereby, the engagement state of the engagement portion and the engagement recess is released without restricting the movement of the handset 10 in the separation direction. Therefore, the handset 10 can be easily detached from the cradle 20. In particular, it is a great advantage of this embodiment that the handset 10 can be easily detached from the cradle 20 with one hand.

  By the way, as shown in FIGS. 2 and 5, an opening 22b is formed in the bottom surface 22a of the recess 22, and from the opening 22b, according to the attachment / detachment of the handset 10 to the cradle 20, The knob 32 of the hook switch 31 for turning on / off the electronic circuit in the cradle 20 is configured to appear and disappear in the recess 22.

  Specifically, as shown in FIG. 5, the hook switch 31 has a planar rectangular knob 32 and an arm portion 33 coupled to the knob 32, and the arm portion 33 is located inside the cradle 20. , Extending in the longitudinal direction of the cradle 20. One end of the arm 33 is pivotally supported by a shaft 34 fixed in the short direction of the cradle 20. On the other hand, the other end of the arm portion 33 is connected to the knob 32. The hook switch 31 is integrally formed using a synthetic resin.

  The hook switch 31 is configured by the spring member 35 so that the knob 32 protrudes into the recess 22 when the handset 10 is not attached. The spring member 35 has a shape in which a coiled portion 38 is formed in the middle between the one end portion 36 and the other end portion 37 using a single metal wire. The coiled portion 38 is attached so as to surround the shaft 34. The one end portion 36 is fixed to the inner surface of the flat surface portion 21. The other end portion 37 supports a projection 39 provided in the width direction of the arm portion 33 (short direction of the cradle 20) from below (on the right side in FIG. 5). The other end portion 37 functions as a spring having an elastic force (restoring force). The other end portion 37 is configured not to be greatly bent by the vibration of the moving body.

  When the handset 10 is mounted on the cradle 20 (when the handset 10 is not used), the knob 32 is pushed against the lower surface 13 a of the earpiece 13. As a result, the other end 37 of the spring member 35 bends downward. Then, the hook switch 31 rotates in one direction with respect to the shaft 34, and the knob 32 retracts into the cradle 20. In this state, the electronic circuit in the cradle 20 is turned off.

  When the handset 10 is detached (during use), the force pushing the knob 32 is released, so that a restoring force acts on the other end 37 of the spring member 35 and lifts the protrusion 39. Then, the hook switch 31 rotates in the other direction with respect to the shaft 34, and the knob 32 is protruded into the recess 22 again. As a result, the electronic circuit in the cradle 20 is turned on.

  With such a configuration of the hook switch 31, the knob 32 of the hook switch 31 is rotated downward by the vibration accompanying the movement of the moving body when the handset 10 is used (when removed), and the electronic circuit is turned on. (The electronic circuit malfunctions) is prevented.

The embodiment described above can be modified as follows. For each recess 22, 23,
Although one engagement portion and an engagement recess are provided, a plurality of engagement portions and engagement recesses may be provided for each of the recesses 22 and 23. The position at which the engaging portion is provided is not limited to the side surface of the concave portion close to the flat surface portion 11 and may protrude from the other side surface.
