[0027]
As shown in FIG. 2, the stand 30 combines the front case 30a and the rear case 30b to support the hook plunger 40 so as to be swingable. On the inner wall surface of the front case 30a of the stand 30, a locking portion 44 and a cylindrical spring holding portion 46 for projectingly supporting the hook plunger 40 are formed so as to project.
[0028]
The spring holding portion 46 fits and holds the spring 45. As shown in FIG. 1, the spring 45 urges the projection 41 of the hook plunger 40 to spring, and the projection 41 is opened from the opening 36b to the case. Make it appearable on the outer surface.
Then, the stand 30 supports the support shaft 43 of the hook plunger 40 on a bearing of a locking portion 44 described later, and makes the hook plunger 40 spring-biased by a spring 45 fitted in the spring holding portion 46. The front case 30a and the rear case 30b are assembled together.
[0029]
As shown in FIG. 4, the hook plunger 40 is formed so that the support shaft 43 has a two-surface width W <b> 1 in which a pair of flat surfaces 43 a and 43 a are arranged to face each other.
On the other hand, the locking portion 44 that supports the hook plunger 40 communicates with the shaft hole 44a and the shaft hole 44a and has a groove width W2 that is substantially coincident with the two-surface width W1 of the support shaft 43 (specifically, the two-surface width). A bearing is formed by the insertion groove 44b having a width slightly larger than W1.
[0030]
Therefore, the support shaft 43 is inserted into the shaft hole 44a by being inserted into the insertion groove 44b while maintaining the posture of the hook plunger 40 so that the flat surfaces 43a and 43a face the wall surface of the insertion groove 44b. Can do.
In a state where the posture of the hook plunger 40 is maintained so that the support shaft 43 can be inserted into the insertion groove 44b, the spring 45 is compressed and deformed as shown in FIG.
[0031]
After the support shaft 43 is inserted into the shaft hole 44 a, when the hook plunger 40 is rotated by releasing the compression deformation of the spring 45, the protrusion 41 at the tip of the hook plunger 40 is brought into contact with the stand 30. Projecting from the outer surface of the case through the opening 36b.
[0032]
Further, as the hook plunger 40 rotates, as shown in FIG. 6, the support shaft 43 rotates so that the flat surfaces 43a and 43a facing the insertion groove 44b are removed from the insertion groove 44b. As a result, the shaft 43 has a shaft diameter larger than the groove width W2 of the insertion groove 44b positioned at the communicating portion with the insertion groove 44b, and cannot be removed from the shaft hole 44a.
[0033]
Therefore, even if the hook plunger 40 is not supported by hand, the hook 43 is temporarily held on the front case 30a side with the support shaft 43 fitted in the shaft hole 44a. Therefore, when the stand 30 is assembled, the rear case 30b can be attached and the cases can be joined together while the hook plunger 40 is temporarily held on the front case 30a.
[0034]
As shown in FIG. 1, the stand 30 is inserted into a not-shown insertion hole formed in the stand fitting portion 15 and the holding claw 33 formed in the bottom portion 31 is temporarily held in the base portion 11. It is fixed to the base part 11 and assembled integrally.
The telephone 1 is assembled by connecting the base unit 11 and the handset 2 with the handset cord 6.
[0035]
When the stand 30 is integrally provided, as shown in FIG. 7, the telephone 1 has a corner portion 36 that supports the handset 2 so as to protrude from the front upper portion of the stand 30.
A hook claw 38 for hooking the handset 2 protrudes from the upper surface 36a of the corner portion 36, and a projection 41 of the hook plunger 40 protrudes in close proximity to the hook claw 38.
[0036]
In the telephone 1 having the above configuration, as shown in FIG. 8, the handset 2 is securely supported by the stand 30 by hooking the locking hole 2g of the handset 2 to the hook claw 38. Since the protrusion 41 of the hook plunger 40 is disposed close to the hook claw 38, the handset 2 can be easily brought into contact with the protrusion 41 regardless of the attachment state thereof, and the protrusion 41 is placed in the stand 30. Can be pushed in.
[0037]
In addition, since the protrusion 41 is formed in a stepped shape equipped with a lower tip surface 2f around the receiving portion 2b of the handset 2 or two surfaces with which the jaw portion 2e comes into contact, as shown in FIG. However, even when the hook claw 38 is placed in the handset receiver in a halfway state where the hook claw 38 is not completely fitted into the insertion hole 2g, for example, the jaw 2e of the handset 2 abuts against the first surface 41a, or the handset The protrusion 41 can be pressed by the lower front end surface 2f around the second receiving portion 2b coming into contact with the second surface 41b.
That is, the handset 2 can press the protrusion 41 on either side thereof, and can always reliably disconnect the telephone line.
[0038]
Thus, since the protrusion 41 is equipped with two steps of a step shape, when the handset 2 is put on the handset receiver, the handset 2 comes into contact with any surface of the protrusion 41 and the hook plunger 40 is moved. It can be pushed into the stand 30.
[0039]
Further, as shown in FIG. 7, the handset 2 has a step even when it is locked to the handset receiver from either the horizontal direction (arrow a direction) or the vertical direction (arrow b direction) of the telephone body 10. The hook plunger 40 can be pushed into the stand 30 by abutting against the protrusion 41 provided with two shaped surfaces.
[0040]
Therefore, even if the handset 2 is locked to the hook claw 38 for receiving the handset from either the horizontal direction or the vertical direction of the stand 30, the protrusion 41 of the hook plunger 40 can be pressed by the handset 2. For this reason, when the handset 2 is put on the hook claw 38, the hook plunger 40 can be surely pushed into the stand 30 by the handset 2.
[0041]
According to the telephone 1 of the present embodiment, since the handset 2 is configured as a new type that is placed vertically with respect to the telephone main body 10, it can be formed compactly with a reduced width dimension compared to a conventional desktop type. At the same time, since the handset can be easily taken from either the left or right side of the telephone body, the handset is suitable for use as a personal computer terminal in parallel with a personal computer, for example.
[0042]
In the above embodiment, the hook plunger 40 is temporarily held by the front case 30a when the stand 30 is assembled. However, the present invention is not limited to this, and the hook plunger 40 is temporarily held by the rear case 30b. It can also be.
In the above embodiment, the handset 2 has been described as a type in which the handset 2 is placed vertically with respect to the telephone body 10. However, the present invention is not limited to such a form, and can be applied to a conventional wall-mounted type or a desktop type. Of course.
[0043]
【The invention's effect】
As described above, the telephone set according to the present invention is formed so that the support shaft of the hook plunger has a two-sided width, and the insertion groove of the bearing has a groove width substantially matching the two-sided width of the support shaft.
Thus, when the support shaft is inserted into the shaft hole through the insertion groove and rotated, the support shaft is prevented from coming out of the shaft hole, and the hook plunger is temporarily held. Therefore, even if the hook plunger is not pressed by hand, the cases can be joined together by supporting the spring-biased hook plunger, so that the assembling work can be easily performed.
[0044]
Further, since the protrusion of the hook plunger is disposed close to the hook claw of the handset receiver, the handset can be easily brought into contact with the protrusion when the handset receiver is put on and can press the protrusion reliably.
In addition, since the protrusion of the hook plunger is formed in a stepped shape equipped with the lower tip surface around the earpiece of the handset or the two surfaces with which the jaw comes into contact, when the handset is brought into contact with the hook plunger, The protrusion can be pressed on either side of the handset.
Therefore, the hook plunger can be surely pushed into the telephone body.
In addition, even when the handset is placed on the handset receiver in a halfway state, the protrusion can be pressed against either surface of the protrusion.
