Abstract

An on-vehicle adaptor for a portable telephone which mounts a portable telephone so that the portable telephone is never disengaged unless a force larger than a certain level is applied thereto. The adaptor includes a case having a recess for receiving a swelled bottom of a large-capacity battery pack mounted to the portable telephone. The case has a pair of guides for guiding both sides of the portable telephone, a first projection adapted for engagement with a retaining slot formed in the portable telephone, and a second projection adapted for engagement with a retaining slot formed in the battery pack. The adaptor also includes a pair of ratchets adapted to enter and leave openings formed in the guides of the case, the ratchets each having a tapered portion whose thickness in the vertical direction is smaller at a front end thereof. Urging means are provided for urging the paired ratchets toward each other. The portable telephone is attached to the adaptor by engagement of the first and second projections with the associated retaining slots. Also disclosed is a portable telephone charger of a structure similar to that of the on-vehicle adaptor.

Claims

1. An adaptor for a portable radio apparatus adapted to mount the portable radio apparatus to a moving body, the portable radio apparatus having a battery pack attached thereto, said battery pack being either a large-capacity battery pack or a small-capacity battery pack adapted to be mounted selectively, said large-capacity battery pack having a swelled bottom, a retaining slot formed in the bottom of both the large-capacity battery pack and that of the small-capacity battery pack, and a retaining slot formed in one end of the portable radio apparatus, said adaptor for the portable radio apparatus comprising:

a case for mounting the portable radio apparatus thereto, said case having a recess formed in a top thereof for receiving the swelled bottom of said large-capacity battery pack, said case further having a pair of guides for guiding both sides of the portable radio apparatus, a first projection adapted for engagement with the retaining slot of the portable radio apparatus, and a second projection adapted for engagement with the retaining slot of the battery pack, with openings being formed opposedly to each other in inner surfaces of said paired guides;

a printed circuit board accommodated within said case, said printed circuit board having a charging circuit formed thereon;

a pair of ratchets adapted to enter and have the openings formed in said guides, said ratchets each having a tapered portion whose thickness in the vertical direction is smaller at a first end thereof;

urging means for urging said paired ratchets toward each other; and

a pair of charging terminals connected electrically to the charging circuit on said printed circuit board and projecting from the top of said case.

2. An adaptor for a portable radio apparatus according to claim 1, wherein said urging means comprises a pair of L-shaped ribs formed integrally with said ratchets respectively, said L-shaped ribs being disposed so that insides of the L-shape ribs are opposed to each other, a support plate for supporting said L-shaped ribs inside said case whereby said ribs are slidable with respect to the case, and a coil spring interposed between said L-shaped ribs.

3. An adaptor for a portable radio apparatus according to claim 1, wherein said urging means comprises a pair of coil springs accommodated within said paired guides of said case.

4. An adaptor for a portable radio apparatus according to claim 1, further having a pair of holes for mounting of a stand and a pair of holes for connection of other devices.

5. A charger for a portable radio apparatus capable of charging a battery pack, said battery pack being attached to the portable radio apparatus, said battery pack being either a large-capacity battery pack or a small-capacity battery pack adapted to be mounted selectively, said large-capacity battery pack having a swelled bottom, a retaining slot formed in the bottom of both the large-capacity battery pack and that of the small-capacity battery pack, and a retaining slot formed in one end of the portable radio apparatus, said charger for the portable radio apparatus comprising:

a case for mounting the portable radio apparatus thereto, said case having a recess formed in a top thereof for receiving the swelled bottom of said large-capacity battery pack, said case further having a pair of guides for guiding both sides of the portable radio apparatus, a first projection adapted for engagement with the retaining slot of the portable radio apparatus, and a second projection adapted for engagement with the retaining slot of the battery pack;

a printed circuit board accommodated within said case, said printed circuit board having a charging circuit formed thereon, and

a pair of charging terminals connected electrically to the charging circuit on said printed circuit board and projecting from the top of said case.

6. A charger for a portable radio apparatus according to claim 5, further having a pair of holes for mounting of a stand and a pair of holes for connection of other devices.

7. A coupling system for the coupling of a portable radio apparatus charger capable of charging a battery pack which is mounted to the portable radio apparatus and a battery pack charger capable of charging the battery pack which is mounted directly to said battery pack charger, said coupling system comprising:

a pair of first through holes formed in said portable radio apparatus charger;

a pair of second through holes formed in said battery pack charger; and

a pair of connecting rods inserted into said first and second through holes for integral coupling of said portable radio apparatus charger and said battery pack charger.

8. A coupling system according to claim 7, wherein each of said connection rods has an elastic engaging projection formed at one end thereof, an engaging key formed at an opposite end thereof, and a stopper formed at an intermediate part thereof;

each of said first through holes comprises a hole portion of a small diameter and a concave portion of a larger diameter;

each of said second through holes has a section of a key hole shape corresponding to said engaging key and has an engaging concave portion at one end thereof whereby when said connecting rods have each been inserted into said portable radio apparatus charger and said battery pack charger up to a position restricted by said stopper, said elastic engaging projection comes into engagement with said concave portion of a larger diameter, and said engaging key comes into engagement with said engaging concave portion.
