Portable computer battery charging apparatus

Claim 2

Apparatus for charging a portable computer battery having a first end portion, and a second end portion longitudinally spaced apart from said first end portion and having disposed thereon a contact area through which electrical charging energy may be transmitted to the battery, said apparatus comprising: a battery support structure having a bottom side supportable on a generally horizontal surface, and a top wall upwardly spaced apart from said bottom side; an open-topped well structure depending from said top wall and having a generally vertically oriented first side wall, said well structure being configured and oriented to removably receive the second end portion of the battery and support the battery in a vertically tilted orientation in which a substantial longitudinal portion of the battery extends upwardly beyond said top wall and the weight of the battery maintains its second end portion in forcible frictional engagement with said first side wall of said well structure; and charging circuit means, carried by said battery support structure, for receiving electrical charging energy from a source thereof and transmitting the received charging energy to the battery, through its contact area, in response to receipt of the second battery end portion in said well structure.

Claim 3

The apparatus of claim 1 wherein: said first side wall of said well structure is vertically tilted at a relatively small angle, and said well structure has a side wall section opposing said first side wall and positioned and configured to be engaged by the well-received second battery end portion and act as a stop to limit the vertical tilt of the battery.

Claim 4

The apparatus of claim 2 wherein said relatively small angle is approximately 15°.

Claim 5

The apparatus of claim 2 wherein said side wall section of said well structure includes: a second, vertically extending side wall, and a horizontally spaced plurality of webs formed on said second side wall and projecting therefrom toward said first side wall.

Claim 6

The apparatus of claim 4 wherein: said webs have inner side edge surfaces which are generally vertically oriented, angled relative to said second side wall, and generally parallel to said first side wall.

Claim 7

The apparatus of claim 5 wherein: said inner side edges of said webs are upwardly sloped away from said first side wall at a slight angle.

Claim 8

The apparatus of claim 1 wherein: said charging structure is a hollow housing having a top portion containing said top wall, and a bottom portion removably connected to said top portion, and said charging circuit means include a power wiring board horizontally disposed within said bottom housing portion in a downwardly spaced apart relationship with said well structure.

Claim 9

The apparatus of claim 7 wherein: said well structure has a bottom end wall with an opening therein positioned to be aligned with the battery contact area when the second battery end portion is operatively received in said well structure, and said charging circuit means further include a resiliently deflectable metal clip member electrically connected to said power wiring board and protruding upwardly through said bottom end wall opening into the interior of said well structure.

Claim 10

Apparatus for charging a portable computer battery having a first end portion, and a second end portion longitudinally spaced apart from said first end portion and having disposed thereon a contact area through which electrical charging energy may be transmitted to the battery, said apparatus comprising: a hollow housing supportable on a generally horizontal surface and having a top wall; open-topped well means depending from said top wall within the interior of said housing and having a generally vertically oriented interior side surface, said well means being operative to removably receive the second end portion of the battery and support the battery in a vertically tilted orientation in which a substantial longitudinal portion of the battery extends upwardly beyond said top wall with the weight of the battery maintaining its second end portion in forcible frictional engagement with said interior side surface of said well means, said well means further having a bottom end wall with an opening therein positioned to be aligned with the battery contact area when the second battery end portion is operatively received in said well means; and charging circuit means, carried by said housing, for receiving electrical charging energy from a source thereof and transmitting the received charging energy to the battery in response to receipt of the second battery end portion in said well means, said charging means including an electrically conductive portion extending upwardly through said bottom end wall opening into the interior of said well means and engageable by the battery contact area when the second battery end portion is operatively received in said well means.

Claim 11

Apparatus for charging a portable computer battery having a first end portion, and a second end portion longitudinally spaced apart from said first end portion and having disposed thereon a contact area through which electrical charging energy may be transmitted to the battery, said apparatus comprising: a hollow housing supportable on a generally horizontal surface and having a top wall; open-topped well means depending from said top wall within the interior of said housing and having a generally vertically oriented interior side surface, said well means being operative to removably receive the second end portion of the battery and support the battery in a vertically tilted orientation in which a substantial longitudinal portion of the battery extends upwardly beyond said top wall with the weight of the battery maintaining its second end portion in forcible frictional engagement with said interior side surface of said well means, said well means further having a bottom end wall with an opening therein positioned to be aligned with the battery contact area when the second battery end portion is operatively received in said well means; and charging circuit means, carried by said housing, for receiving electrical charging energy from a source thereof and transmitting the received charging energy to the battery in response to receipt of the second battery end portion in said well means, said charging means including an electrically conductive portion extending upwardly through said bottom end wall opening into the interior of said well means and engageable by the battery contact area when the second battery end portion is operatively received in said well means.

Claim 12

The apparatus of claim 9 wherein said charging circuit means include: a power wiring board horizontally disposed within said housing beneath said well means, and said electrically conductive portion is a resiliently deflectable clip member electrically connected to said power wiring board.

Claim 13

The apparatus of claim 9 wherein: said well means are operative to support the battery at a vertically tilted angle of approximately 15°.

Claim 14

The apparatus of claim 9 wherein said well means have: a vertically tilted first side wall upon which said interior side surface is disposed, a generally vertical second side wall spaced apart from and facing said first side wall, and a horizontally spaced plurality of webs formed on said second side wall and projecting therefrom toward said first side wall, said webs being positioned to act as stops engageable by the second battery end portion to limit the vertical tilting of the battery.

Claim 15

The apparatus of claim 12 wherein: said webs have inner side edge surfaces which are generally vertically oriented, angled relative to said second side wall, and generally parallel to said first side wall.

Claim 16

The apparatus of claim 13 wherein: said inner side edges of said webs are upwardly sloped away from said first side wall at a slight angle.
