Abstract

A hand holdable light comprises: a light body having a forward portion, a light source proximate a forward end; and one or more switch actuators on the forward end for controlling the light source. The light is holdable by a hand in several ways wherein a finger or thumb is proximate an actuator. A battery assembly comprises: a battery housing for receiving and connecting a battery, an electrical switch on a first end of the battery housing; and a pattern of electrical contacts on a second end of the battery housing, wherein ones of the electrical contacts are connected to the battery.

Claims (51)

1 . A hand holdable light comprising:

a light body having a forward end and a rearward end defining a longitudinal direction therebetween, the light body having a forward portion proximate the forward end thereof and having a rearward portion proximate the rearward end thereof, the light body having a cavity for receiving a source of electrical power;

a light source proximate the forward end of the light body;

a first switch actuator on the forward portion of the light body;

a second switch actuator on the forward portion of the light body proximate to the first switch actuator, wherein the second switch actuator is actuatable by movement lateral to the longitudinal axis;

wherein the first and second switch actuators are closer to the forward end of the light body than to the rearward end thereof;

whereby the hand holdable light is holdable by a hand having a finger or a thumb proximate the first switch actuator and the second switch actuator.

2 . The hand holdable light of claim 1 wherein:

the first switch actuator is actuatable to energize and de-energize the light source; or

the second switch actuator is actuatable laterally to select an operating mode for the light source; or

the first switch actuator is actuatable to energize and de-energize the light source and the second switch actuator is actuatable laterally to select an operating mode for the light source.

3 . The hand holdable light of claim 1 wherein:

the second switch actuator includes a magnet; and

the hand holdable light includes a Hall-effect device or a magnetic reed switch that is responsive to the magnetic field of the magnet of the second switch actuator for selecting an operating mode for the light source.

4 . The hand holdable light of claim 1 wherein the second switch actuator is in line longitudinally with the first switch actuator and is closer to the forward end of the light body than is the first switch actuator.

5 . The hand holdable light of claim 1 wherein the light body has a longitudinal groove proximate to the first switch actuator.

6 . The hand holdable light of claim 1 wherein the light body:

includes a third actuator on the rearward end of the light body; or

includes a third actuator disposed in a transverse groove on the rearward end of the light body.

7 . The hand holdable light of claim 1 wherein the light body has a cover for covering an opening into the cavity of the light body for receiving a source of electrical power therein, wherein the source of electrical power includes an electrical switch on an end thereof that is proximate the cover when the source of electrical power is in the cavity of the light body, and wherein:

the cover has an opening through which the electrical switch of the source of electrical power is actuatable from external to the light body; or

the cover has a flexible seal covering the opening through which the electrical switch of the source of electrical power is actuatable from external to the light body.

8 . The hand holdable light of claim 1 wherein the light body defines one or more broad surfaces, the hand holdable light further having:

a pattern, a coating or a sheet material on the one or more broad surfaces;

wherein the pattern, coating or sheet material has a higher coefficient of friction than do the one or more broad surfaces when not patterned or covered.

9 . The hand holdable light of claim 1 wherein the light body has a cover for covering an opening into the cavity of the light body for receiving a source of electrical power therein, wherein the light body and the cover have respective complementary features providing a latch for retaining the cover in a closed position adjacent the opening of the light body.

10 . The hand holdable light of claim 9 wherein the cover is hinged at one end thereof and the latch is at the other end thereof, the latch including:

a loop or a clasp on the light body or light body for engaging a latch feature of the light body or cover for retaining the cover in a closed position adjacent the opening of the light body; or

a clasp wherein a single metal piece is formed and attached to the light body to provide the clasp and a clip.

11 . The hand holdable light of claim 9 , wherein the cover is hinged at one end thereof and the latch further comprises a loop, a clasp, a clip, a post or a screw for releasably retaining the cover in the closed position.

12 . The hand holdable light of claim 1 wherein the light body has a cover for covering an opening into the cavity of the light body for receiving a source of electrical power therein, wherein the cover includes a third switch actuator for selectively energizing the light source from the source of electrical power.

13 . The hand holdable light of claim 12 wherein the source of electrical power includes an electrical switch for selectively energizing the light source, and wherein the third switch actuator actuates the electrical switch of the source of electrical power.

14 . The hand holdable light of claim 1 :

wherein the source of electrical power includes a battery assembly having a symmetrical pattern of externally accessible electrical contacts on an end thereof that is proximate the forward end of the light body, and

wherein the light body includes at least two electrical contacts positioned for making respective electrical connections to predetermined ones of the symmetrical pattern of electrical contacts of the battery assembly when the battery assembly is in the cavity of the light body,

whereby proper electrical connections are made to the battery assembly irrespective of its orientation in the cavity of the light body.

15 . The hand holdable light of claim 1 , further comprising:

a battery assembly that may be inserted into the cavity in more than one possible orientation, the battery assembly further comprising electrical contacts positioned thereon symmetrically in relation to the longitudinal axis such that, for more than one orientation of insertion, the battery provides electrical power to the light source.

16 . A hand holdable light comprising:

a light body having a forward end and a rearward end defining a longitudinal direction therebetween, and having a cavity for receiving an electrical power source;

a light source proximate the forward end of the light body;

a first switch actuator on a forward portion of the light body;

a second switch actuator on the forward portion of the light body proximate to the first switch actuator, wherein the second switch actuator is actuatable by movement lateral to the longitudinal axis; and

an electrical power source that can be inserted into the cavity in more than one possible orientation, the electrical power source further comprising electrical contacts positioned thereon symmetrically in relation to the longitudinal axis such that, for more than one orientation of insertion, the electrical power source provides electrical power to the light source.

17 . A hand holdable light comprising:

a light body having a forward end and a rearward end defining a longitudinal direction therebetween, and having a cavity for receiving a source of electrical power;

a light source proximate the forward end of the light body;

a first switch actuator on a forward portion of the light body;

a second switch actuator on the forward portion of the light body proximate to the first switch actuator, wherein the second switch actuator is actuatable by movement lateral to the longitudinal axis;

the electrical power source having a symmetrical pattern of four electrical contacts evenly and symmetrically disposed around a circle and a fifth electrical contact at the center of the circle.

18 . The hand holdable light of claim 17 wherein the light body includes plural electrical contacts that are positioned for making respective electrical connections to the symmetrical pattern of electrical contacts of the electrical power source.
