ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to battery pack removing device, and more particularly to a battery pack removing device which is used to mount a battery pack in or detach the same from a small radio terminal unit such as a portable telephone set.
FIGS. 8 and 9
show the relation between the body of a conventional portable telephone set and a conventional battery pack. More specifically,
FIG. 8
is a perspective view showing a battery pack
50
mounted in a portable telephone set body
10
, and
FIG. 9
is also a perspective view showing only the portable telephone set body
10
.
The battery pack
50
is mounted in the portable telephone set body
10
as follows: With the hooks of the battery pack
50
fitted in recesses formed in the bottom section of the portable telephone set body
10
, the battery pack
50
is pushed into the portable telephone set body
10
while being swung towards the latter
10
. As a result, the head section of the battery pack
50
is brought into contact with the sloped surface of the slide pawl
21
of the slide knob
20
of the telephone set body
10
, thus pushing down the slide pawl
21
. Hence, the slide pawl
21
of the slide knob
20
of the portable telephone set body
10
is engaged with a recess formed in the head section of the battery pack
50
. Thus, the battery pack
50
has been mounted in the portable telephone set body
10
. The portable telephone set body
10
has right and left side walls which are confronted with each other, and the inner surfaces thereof have protrusions
32
. On the other hand, the battery pack
50
has right and left side walls on which protrusions are formed, respectively, so that they are engaged with the protrusions
32
of the side walls of the portable telephone set body
10
, which prevents the play of the battery pack
50
with respect to the portable telephone set body
10
.
The portable telephone set body
10
has power source spring terminals
40
, and in correspondence to those terminals
40
the battery pack
50
has power source terminals. The power source terminals are brought into contact with power source spring terminals
40
, so that current is allowed to flow to the portable telephone set body
10
.
The battery pack
50
is detached from the portable telephone set body
10
as follows: The slide knob
20
of the portable telephone set body
10
is slid; that is, the slide pawl
21
is slid, thus disengaging from the battery pack
50
. The latter
50
is moved upwardly by the elastic force of the power source spring terminals
40
. Hence, by holding the protrusions
65
(which are formed on the outer surfaces of the right and left side walls of the battery pack) with the fingers, the battery pack
50
can be removed from the portable telephone set body.
In the case of Japanese Patent Application Publication No. 9-330687/(1997), 10-70595/(1998), or 10-144274/(1998), the battery pack is pushed upwardly with a push-up member or the like, so as to be removed from the portable telephone set body.
As was described above, the conventional battery pack
50
is pushed upwardly by the elastic force of the power source spring terminals
40
; however, the elastic force is not strong enough. Hence, in order to remove the battery pack
50
from the telephone set body
10
, it is necessary to use the protrusions
65
formed on the right and left side walls of the battery pack
50
; that is, it is necessary to hold the protrusions
65
with the fingers and to pull the battery pack
50
upwardly. Therefore, it is rather difficult to remove the battery pack
50
, and during the use of the portable telephone set those protrusions obstructs the operation of the portable telephone set. In addition, the protrusions spoil the external appearance of the portable telephone set as a whole.
As was described above, the battery pack may be pushed upwardly with the push-up member or the like. However, in this case, the portable telephone set is intricate in structure, and large in the number of manufacturing steps, and accordingly high in manufacturing cost, and difficult in miniaturization.
SUMMARY OF THE INVENTION
Accordingly, an object of the invention is to eliminate the above-described difficulties accompanying a conventional portable telephone set. More specifically, an object of the invention is to provide a battery pack removing device which is simple in structure and with which the battery pack is readily and positively mounted in or detached from the portable telephone set body.
In order to solve the above-described problems, a battery pack removing device is provided which, according to the invention, has a slide protrusion which is formed on an electronic device such as a portable telephone set. The slide protrusion is integral with a slide pawl which is engageable with a recess formed in the head section of a battery pack. When the slide pawl is slid, the slide protrusion is brought into contact with the protrusion formed on the back of the battery pack, so that the head section of the battery pack is forcibly pushed out of the electronic device, whereby the battery pack can be removed from the electronic device with ease.
With the battery pack removing device, the side protrusions are eliminated which are formed on the conventional battery pack to mount the latter in the electronic device or to detach the same from the latter. That is, the battery pack removing device is simple in structure. And yet the battery pack mounting or detaching operation can be positively achieved with ease.
According to the present invention, it is provided a battery pack removing device for removing from an electronic device a battery pack which has a recess in a head section thereof, and a hook formed in a bottom section thereof, and a back protrusion on the back of the head section, and which is separable from the electronic device; in which the electronic device includes: a bottom recess engageable with the hook, a slide pawl engageable with the recess in the head section of the battery pack, and a slide protrusion which is integral with the slide pawl, and which, when the slide pawl is slid, is slid and brought into contact with the back protrusion, thereby to forcibly push the head of the battery pack out of the electronic device.
With the device, the slide protrusion of the electronic device body pushes the back protrusion of the battery pack upwardly, so that the battery pack is positively pushed upwardly.
According to the present invention, it is provided a portable telephone comprises: a battery pack detachable from a portable telephone body, the battery pack including: a recess in a head section thereof; a hook formed in a bottom section thereof; and a back protrusion on the back of said head section, the portable telephone body includes: a bottom recess engageable with said hook; a slide pawl engageable with said recess in the head section of the battery pack; and a slide protrusion which is integral with the slide pawl, and which, when the slide pawl is slid, is slid and brought into contact with the back protrusion, thereby to forcibly push the head of the battery pack out of the electronic device.
With the device, the slide protrusion of the portable telephone set body pushes the back protrusion of the battery pack upwardly, so that the battery pack is positively pushed upwardly.
