Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charger for a portable electronic device, and more particularly to a locking device for the charger for a portable electronic device which prevents the portable electronic device from falling during charging.

[0002]

2. Description of the Related Art A portable electronic device such as a mobile phone is equipped with a rechargeable battery and is used while appropriately charging the battery with a charger. This type of mobile phone and its charger are shown in FIG.
Will be explained.

In the mobile phone 1, an antenna 4 is erected on the upper end of a case 3 which is formed in an elongated box shape so that it can be easily held.
From the top to the bottom of the front surface 3a, the speaker 7, the display unit 5,
The operation button groups 6 and the like are sequentially arranged side by side, and it is possible to carry and carry out an operation call.

In the charger 2, a shallow horizontal pedestal 16 is formed with a concave portion 17 opening upward, and the lower end portion 3b of the case 3 is fitted into the concave portion 17 so that the portable telephone 1 can be carried. The telephone 1 is held in the upright state with the front surface 3a thereof facing forward. Further, in order to prevent the mobile phone 1 from toppling over during charging, a support portion 18 formed in a U-shape in a plan view is integrally provided at a predetermined height on the rear portion of the pedestal 16 so that the mobile phone 1 can be held. It is possible to contact the left and right side portions 3c of the telephone 1 and the rear portion 3d. Reference numeral 15 in the drawing is a battery holder for charging the battery alone.

When the mobile phone 1 is charged, the lower end portion 3b of the mobile phone 1 is recessed in the pedestal 16.
The left and right side portions 3c and the rear portion 3d are housed in the supporting portion 18, and the mobile phone 1 is placed vertically on the charger 2. Also during charging, the charger 2
When vibration or shock is applied to the mobile phone 1 and the mobile phone 1 sways in a vertically standing posture, the mobile phone 1 comes into contact with the supporting portion 18 to prevent the mobile phone 1 from tipping over on the left, right, and rear sides of the mobile phone 1. It has such a structure.

[0006]

However, in the above-mentioned conventional technique, the charger 2 is simply provided with the support portion 18 having a U-shape in plan view on the rear side of the receiving base 16. Therefore, when the mobile phone 1 leans forward during charging, it cannot be supported, and therefore the mobile phone 1 is likely to fall forward of the arrow. As a result, the mobile phone 1 may be detached from the charger 2 and the charging may be insufficient, or the mobile phone 1 may fall onto the floor and cause a failure.

Therefore, it is required to attach a lock device to the mobile phone 1 so as to prevent the mobile phone 1 from falling forward during charging. As a locking device, it is conceivable that the mobile phone 1 and the charger 2 are provided with a groove and a ridge that fits in the groove, and the mobile phone 1 is locked by fitting the groove into the ridge. However, since a high processing accuracy is required for fitting the groove and the protrusion, the cost is increased, and the operability when the mobile phone 1 is put in and out of the charger 2 may be deteriorated. There are problems such as

In view of the above situation, it is an object of the present invention to provide a lock device for a charger for a portable electronic device which is inexpensive and can lock the portable electronic device reliably.

[0009]

In order to achieve this object, a portable electronic device can be inserted into a portable electronic device housing formed by a concave portion opened upward and a supporting portion continuous with the concave portion. It is characterized in that a spring piece having a projection at its tip is provided on a wall surface adjacent to the storage portion of the support portion, and a concave portion engageable with the projection is formed on a side surface of the portable electronic device.

Therefore, when the mobile phone is placed upright on the charger during charging, the mobile phone is charged. Vibration and shock are applied to the charger and the like during charging, and even if the mobile phone sways due to its upright posture, the spring force of the spring piece holds it in the locked state.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing an example of an embodiment of a lock device for a charger for portable electronic equipment according to the present invention.

In the mobile phone 1, an antenna 4 is erected on the upper end of a case 3 which is formed in an elongated box shape so as to be easy to hold.
The speaker 7, the display unit 5, the operation buttons 6, the microphone 8 and the like are sequentially arranged from the top to the bottom of the front surface 3a, and it is possible to carry and carry out a call operation.

In the charger 2, a shallow horizontal pedestal 16 is formed with a concave portion 17 which opens upward, and the lower end portion 3b of the case 3 is fitted into the concave portion 17 so that the portable telephone 1 can be carried. The telephone 1 is held in the upright state with the front surface 3a thereof facing forward. Further, in order to prevent the mobile phone 1 from toppling over during charging, a support portion 18 formed in a U shape in a plan view is integrally provided at a rear portion of the pedestal 16 at a predetermined height. It is possible to contact the left and right side portions 3c of the mobile phone 1 and the rear portion 3d. In the figure, 15
Is a battery holder for charging the battery alone.

Further, a lock device 20 is provided to prevent the mobile phone 1 from falling forward while being charged. The lock device 20 will be described. Recesses 21 are provided in the left and right side portions 3c of the mobile phone 1, and the recess portions 21 are formed at the widest portion of the approximate center of the side portion 3c, and the portion is inclined downward with a small inclination. Has been done. Further, a spring piece 23 having a protrusion 22 at a tip 23a is formed in a cantilever shape at substantially the same height as the recesses 21 on the left and right side surfaces 18a of the support portion 18.

The spring piece 23 is formed by notching the side surface 18a so as to form a groove 24 having a concave cross section from the front opening 18b rearward, and connecting the base end 23b to the supporting portion 18. Thus, the spring piece 23 is provided integrally with the side surface 18a of the supporting portion 18 in the same lateral direction as the side surface 18a, and the spring piece 23 has a predetermined spring property that bends within the range of the groove 24. It will be a good thing.

With the mobile phone 1 fitted in the recess 17, the protrusion 22 can be engaged with the recess 21, and the state in which the protrusion 22 is engaged with the recess 21 is a locked state. . Therefore, at the time of locking, it suffices to apply a spring force by the spring piece 23 so that the protrusion 22 does not come off the recess 21, and the spring force moves when the mobile phone 1 is vibrated or shocked. The lock strength is set to the extent that restrains. Since the mobile phone 1 is portable and lightweight, the spring force of the spring piece 23 can be set weakly, and by making the bending amount of the spring piece 23 sufficiently large, it becomes possible even if the processing accuracy is low. Furthermore, troubles such as the charger 2 being lifted up together can be avoided.

Therefore, in the above structure, when the mobile phone 1 is charged, the mobile phone 1 is placed vertically on the charger 2 with the lower end portion 3b placed on the recess 17 of the receiving stand 16. When placed, the mobile phone 1 is charged,
The left and right side portions 3c and the rear portion 3d are housed in the support portion 18. At the same time, the protrusion 22 of the spring piece 23 of the lock device 20 engages with the recess 21 of the left and right side portions 3 c of the mobile phone 1.

Even if vibration or impact is applied to the charger 2 or the like during charging, the spring piece 23 is engaged with the mobile phone 1, so that the fall is prevented.

Since the spring piece 23 is provided integrally with the charger 2, an increase in the number of parts is avoided, and the spring piece 23 is flush with the side surface 18a of the support portion 18. It doesn't get in and out of.

Although the embodiment of the present invention has been described above, the present invention is not limited to this. For example, the spring piece 23
May be placed in the vertical or diagonal direction in addition to the horizontal direction,
Alternatively, it may be formed as a separate part.

[0022]

As described above, according to the present invention, the portable electronic device can be inserted into the portable electronic device housing formed by the concave portion opened upward and the supporting portion connected to the concave portion. Since the spring piece having the projection at the tip is provided on the wall surface adjacent to the storage portion, and the concave portion that can be engaged with the projection is formed on the side surface of the portable electronic device, it is possible to prevent the portable electronic device from falling forward. It can be surely prevented. Since it suffices to set the spring force of the spring piece to be weak, the processing accuracy may be low and the manufacturing cost is reduced.
