DETAILED DESCRIPTION OF THE INVENTION

(17) The present application hereby incorporates by reference in its entirety U.S. Provisional Patent Application No. 62/706,068, on which this application is based.

(18) The present invention is a light 10 that mounts to the back of the hand 2, so as to free the hand 2 for other duties. The basic components of the light are a housing 12, a narrow beam lamp 14, a wide beam lamp 16, a band 18, power control 20, and a power source 22. The light 10 of the present invention is designed to be as unobtrusive as practical so that, when worn, it has minimal effect on the user while providing the desired functionality.

(19) When the light 10 is in use on the left hand, it is typically oriented as shown in FIGS. 6 and 15. Each face has a designation. The face from where the light emits is the front 26 and the opposite face is the back 28. The upper face is the top 30 and the opposite face is the bottom 32. The top 30 and bottom 32 are reversed if the user wears the light 10 on the right hand. The face toward the hand 2 is the inside 34 and the opposite face is the outside 36.

(20) The housing 12 is composed of a high-impact, lightweight, rigid material, such as a plastic, composite, or aluminum alloy. The size and shape of the housing 12 is determined, in part, by the size of the power source 20, described below. Optionally, the housing 12 is watertight.

(21) On the front 26 of the housing 12 are two openings 40, 42, one for the narrow beam lamp 14 and the other for the wide beam lamp 16. The line of alignment 48 of the lamps 14, 16 is generally parallel to the inside 34. Each lamp 14, 16 has one or more light-emitting diodes (LEDs) as a light source that emits light into a corresponding lens system 44, 46. The lenses of each lens system 44, 46 are chosen by methods well-known in the art to form a beam with the desired divergence, the angle at which the beam spreads out from the lamp opening 40, 42. For the narrow beam, the divergence is in the range of from 5° to 30°. For the wide beam, the divergence is in the range of from 45° to 100°.

(22) In one configuration, the beam divergence is fixed, that is, each lens system 44, 46 is fixed to form a beam divergence that cannot be adjusted. In another configuration, the beam divergence is adjustable. Typically, one lens of a compound lens is mounted in a rotating bezel that is manually rotated to adjust the divergence. The bezel can include detents so that the bezel does not rotate unintentionally.

(23) The power control 20 controls the luminosity of the lamps 14, 16 and can take a number of different forms. One configuration of the power control 20 is shown in FIG. 7. In this configuration, each lamp 14, 16 has a fixed luminosity. Preferably, the fixed luminosity is at least 500 lumens for the narrow beam, and at least 200 lumens for the wide beam. An on/off switch 140, 142 for each lamp 14, 16 merely feeds power from the power source 22 to the corresponding lamp 14, 16. The switches 140, 142 can be located on the top 30 and/or bottom 32 to allow for right-handed and left-handed operation.

(24) In a more versatile configuration of the power control 20, the luminosity of each lamp 14, 16 is fixed at one of several levels. A multi-position switch for each lamp 14, 16 merely feeds the right amount of power from the power source 22 to the corresponding lamp 14, 16, where there is an off position and two or more on positions. One position will typically be full luminosity and other position(s) will attenuate luminosity by some amount by, for example, ⅓ and ⅔. The switches can be located on the top 30 and/or bottom 32 to allow for right-handed and left-handed operation.

(25) More complicated configurations typically include an electronic controller 24, located within the housing 12, to control the operation of the light 10. The controller 24 takes as input the power source 22 and various controls, discussed below, and drives the lamps 14, 16. The configurations described above can be implemented with a controller 20.

(26) In one configuration, shown in FIGS. 8 and 9, the luminosity of each lamp 14, 16 is preset by a switch 146, 148 associated with each lamp 14, 16 and a master switch 150 implements the presets. More specifically, pushbuttons cycle through each of the luminosity levels of the lamps 14, 16 without turning them on. For example, the narrow beam lamp switch 146 cycles through high-low-strobe-off and the wide beam lamp switch 148 cycles through high-low-off. The lamp pushbuttons 146, 148 are on a panel on the top and/or bottom of the housing 12. Optionally, an indicator shows the setting for each of the lamps 14, 16. A master switch 150 on the top 30 and/or bottom 32 of the housing 12 applies power to the lamps 14, 16 using the pushbutton settings. The master switch 150 can be a pushbutton or a toggle switch.

(27) In another configuration, there is a single switch for each lamp 14, 16 that provides all the control for its associated lamp 14, 16. Each switch cycles through the settings for its associated lamp 14, 16. Optionally, there are duplicate sets of switches providing the same functions, one set on the top 30 and one on the bottom 32 to allow for right-handed and left-handed operation.

(28) Preferably, the color temperature of the lamps 14, 16 is at least 4000 K so that they illuminate objects more sharply.

(29) Power is supplied by a power source 22 that includes one or more internal batteries 154. In one configuration, the batteries 154 are rechargeable, and the appropriate recharging power is supplied through a socket. In the preferred configuration, the batteries 154 are replaceable through a hatch 156 in the bottom 32 of the housing 12. The replaceable batteries 154 can be rechargeable or not rechargeable. Replaceable batteries 154 permit the user to quickly replace them in the field.

(30) Preferably, the batteries 154 provide at least two hours of operation at the highest usage level.

(31) Optionally, a battery level indicator 170 shows the status of the battery 154. When the light 10 is off, indicator 170 can show the battery level. When the light 10 is on, the indicator 170 can show either the battery level or the approximate amount of time that the battery 154 can maintain the current usage level of the light.

(32) Replaceable batteries 154 are installed and removed through the hatch 156. The hatch 156 has a door 158 that is hinged at one end, as at 160, to swing away from the battery opening 162. The other end of the door 158 has a latch 164 to secure the door 158 closed, thereby securely retaining the batteries 154 in the housing 12. Optionally, the hatch 156 includes a watertight seal around the perimeter.

(33) The light 10 is mounted to the back of the hand 2 by the band 18, which includes a bracket 50 and a strap 52 that combine to encircle the hand 2. The bracket 50 is an elongated strip of lightweight material, such as a plastic or aluminum alloy, that is attached to the inside 34 of the housing 12. The bracket 50 is oriented such that it runs generally vertically across the housing inside 34. The bracket 50 is attached to the housing 12 by whatever means is appropriate and can be permanent or removable. In one configuration, the bracket 50 is attached by one or more screws 54 through holes 56 in the bracket 50 and into threaded holes 58 into the housing inside 34. If one screw 54 is used, as in FIG. 13, the bracket 50 can be rotated to adjust the lamps 14, 16 up and down relative to the back of the hand 2. Alternatively, if the bracket 50 is to be in a fixed position, optional features on the inside 34 prevent the bracket 50 from rotating relative to the housing 12. Alternatively, more than one screw 54 can be used to prevent the bracket 50 from rotating, as in FIG. 14.

(34) Optionally, the screws 54 are countersunk or otherwise recessed to keep from rubbing on the back of the hand 2 while in use. Alternatively, the screws 54 are covered by a softer material to isolate the screws 54 from the back of the hand 2.

(35) The light 10 optionally includes a mechanism for adjusting the location of the light 10 relative to the back of the hand 2. In an example of such a mechanism, the screw hole 56 in the bracket 50 is a slot, either vertical, horizontal, or both as a plus sign shape. When the screw 54 is loosened, it can be moved within the slot 56 to adjust the vertical or horizontal position of the light 10 on the hand 2.

(36) The light 10 optionally includes a mechanism for adjusting the distance of the light 10 relative to the back of the hand 2. In an example of such a mechanism, a spacer can be installed on the screw 54 between the housing 12 and the bracket 50. The thickness of the spacer determines the distance between the housing 12 and the back of the hand 2.

(37) The light 10 optionally includes a mechanism for adjusting the side-to-side angle of the light 10 relative to the back of the hand 2. In an example of such a mechanism, a wedge-shaped spacer can be installed on the screw 54 between the housing 12 and the bracket 50. When the thicker portion of the spacer is toward the front, the lamps 14, 16 are angled away from the back of the hand 2. When the thicker portion of the spacer is toward the back, the lamps 14, 16 are angled toward the back of the hand 2.

(38) A more flexible mechanism for adjusting the angle of the light 10 relative to the hand is a ball joint 100, shown in FIGS. 11 and 12. The ball joint 100 has a convex outer spherical bearing surface 102 on the inside 34 of the housing 12. A mating concave outer spherical bearing surface 104 is on a spacer 106 straddling the hole 52 in the bracket 50. A clevis pin 108 with a head 110 abutting the bracket 50 extends through the bracket hole 52 and a hole 112 in the spacer 106, though a hole 114 in the center of the outer convex spherical bearing surface 102, and through a hole 118 through the center of a truncated sphere 116. The surface of the sphere 116 is a convex inner spherical bearing surface 120 that abuts a concave inner spherical bearing surface 122 that is within and concentric with the concave outer spherical bearing surface 104. A C-clip 124 secures the clevis pin 108 with the C-clip 124 abutting the truncated surface 126 of the sphere 116. Alternatively, the truncated sphere hole 118 and the clevis pin 108 are threaded, and the clevis pin 108 is turned into the truncated sphere hole 118. In this configuration, the C-clip 124 is optional and the sphere 116 may or may not be truncated. The hole 114 in the center of the outer convex spherical bearing surface 102 is conical, as at 128.

(39) The ball joint 100 includes a mechanism to retain the housing 12 in the desired position. In one configuration, the mechanism is merely a tight fit between components. In the case, the ball joint is hard to adjust, but stays where it is. In another configuration, a spring is installed on the clevis pin 108, for example, between the C-clip 124 and the truncated surface 126, that pulls the bearing surfaces together.

(40) Referring to FIG. 11, the ball joint 100 permits adjustment over three dimensions in roll (XY plane, rotation on the Z axis), pitch (YZ plane, rotation on the X axis with the light beams moving up and down), and yaw (XZ plane, rotation on the Y axis with the light beams moving side to side). In roll, the angle of motion is limited by several factors, including the height of the light 10 and the thickness of the spacer 106. In the present design, the angle of motion is approximately ±2°. In pitch, without stops, there is no limit; it can spin a full 360° around the bracket 50. To limit motion, stops on either the bracket 50 or the inside 34 of the housing 12 can keep the light 10 pointing forward. Typically, the pitch will be limited in a range at least ±10° up to ±20°. In yaw, the angle of motion is limited by several factors, including the length of the light 10, the thickness of the spacer 106, and how it is mounted on the user's hand 2. Typically, the yaw will have a minimum range of at least ±2° and up to ±10°.

(41) The bracket 50 extends beyond the sides of the housing 12. The ends of the bracket 50 are typically curved away from the housing 12, as at 70, so that it partially cups the back of the hand 2. Lateral strap slots 72 at the ends 74 of the bracket 50 hold the strap 52.

(42) The strap 52 is a strip of flexible material, such as a nylon, polyester, or polypropylene webbing. Optionally, the strap 52 is elastic. The strap 52 is attached to the bracket 50 by the strap slots 72. The strap 52 can be permanently or removably attached. A permanent attachment can be threading the end of the strap 52 through the strap slot 72, folding it over, and sewing the overlapping sections together.

(43) Another permanent attachment can be inserting the end of the strap 52 through the strap slot 72, and then looping the end of the strap 52 around the center bar of a ladder lock and sewing the overlapping sections together. The ladder lock is longer than the strap slot 72 and so cannot fit through the strap slot 72, thereby retaining the strap 52.

(44) A removable attachment permits replacing the strap 52 with one of a different length. Two contemplated removable attachments are shown in FIGS. 13 and 14. In FIG. 13, the end of the strap 52 is looped around the center bar 78 of a ladder lock 76 and the overlapping sections are sewn together, as at 80. The ladder lock 76 is shorter than the strap slot 72 and the combination ladder lock 76 and strap 52 is thinner than the strap slot 72, and so slips through the strap slot 72, as at 82. When the strap 52 is pulled, as when wearing, the ladder lock 76 sits flat against the bracket 50, as in FIG. 11, thereby retaining the strap 52.

(45) In FIG. 14, the end of the strap 52 is looped through a slot 84 of a toggle 82 and the overlapping sections are sewn together, as at 86. The toggle 82 is longer than the strap slot 72 and the combination toggle 82 and strap 52 is thinner than the strap slot 72. The toggle 82 slips through the strap slot 72 starting at its end 88. When the strap 52 is pulled, as when wearing, the edge 90 of the toggle 82 sits flat against the bracket 50, retaining the strap 52.

(46) The light 10 can be mounted to a duty belt or vest by any practical means. The light 10 can be stored in a pouch or attached by a quick release mechanism, such as taught in U.S. Pat. No. 11,064,796.

(47) When visibility dictates, the light 10 is removed from its storage and the non-shooting hand is slipped into the band 18. The light 10 is positioned so the inside 34 is adjacent to the back of the hand 2, as in FIG. 15. The light 10 frees the hand 2 to open a door, support the weapon, etc.

(48) Thus, it has been shown and described a hand mounted light. Since certain changes may be made in the present disclosure without departing from the scope of the present invention, it is intended that all matter described in the foregoing specification and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
