## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to portable lighting devices and, more particularly, to hand held or mounted portable lighting devices.
2. Description of the Related Art
A large variety of portable lighting devices are known in the art and are used for a broad range of different functions. Many such portable lighting devices are designed to provide a signaling function wherein the activation of the lighting device is done to communicate information to another person or merely to enhance the visibility of the individual in possession of the portable lighting device.
The use of a portable, selectively actuable signaling light can be particularly advantageous for bicycle riders. The use of a light when riding a bicycle can greatly enhance the visibility of the rider, particularly in low light conditions, and thereby enhance the safety of the rider. While various portable lighting devices are known, including lighting devices adapted for use on bicycle, an improved lighting device is desirable.
SUMMARY OF THE INVENTION
The present invention provides an apparatus that can be worn on a user's hand and which includes a selectively activated light source. The device is well adapted for use by a cyclist, however, the device may also be used in a wide variety of other applications. The invention comprises, in one form thereof, an apparatus controllable by a hand of a user. The apparatus includes at least one article of apparel mountable on the hand of the user wherein the apparel is repositionable between a first configuration and a second configuration as the user's hand is repositioned between a first shape and a second shape. An electrical power source is provided. A light source is disposed on the apparel and emits light when energized by the electrical power source. Also located on the apparel is an electrical circuit that is operably coupled with the electrical power source and the light source and a flexure responsive circuit element that is coupled with the electrical circuit. The flexure responsive circuit element and apparel define a layered structure wherein movement of the apparel between the first configuration and the second configuration flexes the layered structure with the flexure responsive circuit element having a first shape when the apparel is in the first configuration and a second shape when the apparel is in the second configuration. Movement of the circuit element between the first and second shapes subjects the circuit element to a change in curvature and strain. The circuit element has a first set of operating characteristics within the electrical circuit when it is positioned in its first shape and a second set of operating characteristics when it is in its second shape. The energizing and de-energizing of the light source is responsive to the operating characteristics of the circuit element.
The invention comprises, in another form thereof, an apparatus controllable by a hand of a user. The apparatus includes at least one article of apparel mountable on the hand of the user wherein the apparel is repositionable between a first configuration and a second configuration as the user's hand is repositioned between a first shape and a second shape. An electrical power source is provided. A light source is disposed on the apparel and emits light when it is energized by the electrical power source. An electrical circuit is also disposed on the apparel and is operably coupled with the electrical power source and the light source whereby the light source is selectively energized by the electrical power source through the electrical circuit. Additionally, a control circuit is disposed on the apparel and operably coupled with the electrical circuit and a flexure responsive circuit element disposed on the apparel is operably coupled with the control circuit. The flexure responsive circuit element has a first shape when the apparel is in its first configuration and a second shape when the apparel is in its second configuration. The circuit element has a first set of operating characteristics within the electrical circuit when it is positioned in its first shape and a different, second set of operating characteristics when the circuit element is positioned in its second shape. The control circuit energizes and de-energizes the light source in response to the operating characteristics of the flexure responsive circuit element.
The control circuit may, optionally, be configured to define at least three modes of operation of the light source. These three modes of operation include: (a) an energized mode wherein said light source is continuously energized; (b) a de-energized mode wherein said light source is continuously de-energized; and (c) a flashing mode wherein said light source is repeatedly energized and de-energized. The mode of operation is determined by selectively flexing the flexure responsive circuit element between said first and second shapes of the circuit element.
The invention comprises, in yet another form thereof, a method of operating a light source. The method includes providing at least one article of apparel wherein the apparel is wearable by a user proximate a hand of the user. The apparel is repositionable between a first configuration and a second configuration as the user's hand is repositioned between a first shape and a second shape. The method also includes mounting the light source and a flexure responsive circuit element on the apparel. The flexure responsive circuit element has a first shape when the apparel is in its first configuration and a second shape when the apparel is in its second configuration. The circuit element has a first set of operating characteristics when positioned in the first shape and a different second set of operating characteristics when the circuit element is positioned in its second shape. The method further includes selectively energizing and de-energizing the light source in response to the operating characteristics of the circuit element.
An advantage of the present invention is that it provides a light source that can activated by a user merely by changing the shape of the user's hand, e.g., from a grasping shape to an outstretched shape. This allows a bicyclist to easily energize and de-energize the light source merely by releasing their grip on a handlebar and outstretching their hand to energize the light and subsequently regripping the handlebar to de-energize the light.

Although the exemplification set out herein illustrates embodiments of the invention, in several forms, the embodiments disclosed below are not intended to be exhaustive or to be construed as limiting the scope of the invention to the precise forms disclosed.
DETAILED DESCRIPTION OF THE INVENTION
An apparatus 20 in accordance with the present invention is illustrated in FIGS. 1 and 2. Apparatus 20 includes an article of apparel 22 that is mounted proximate a user's hand 24. In the illustrated example, article of apparel 22 is a glove that closely fits the user's hand 24 covering the hand 22 from a point near wrist 26 to the ends of fingers 30 and including the metacarpal region 28 between wrist 26 and fingers 30.
Mounted on the backside of glove 22 is an electrical power source 32, wiring 34, electrical switch 36 and a light source 44. In the embodiment of FIGS. 1-3, electrical power source 32 takes the form of a rigid battery pack which receives conventional alkaline batteries and provides means for coupling wiring 34 to the batteries and light source 44 takes the form of an incandescent lamp having a filament. Battery 32, wiring 34 and light 44 can be mounted to glove 22 using adhesives, tape, stitching or other suitable means.
FIG. 3 provides a schematic representation of the device 20 illustrated in FIGS. 1 and 2. As can be understood with reference to FIGS. 1-3, wiring 34 and electrical switch 36 form an electrical circuit 35 that is located on glove 22 and which is operably coupled to both battery 32 and light source 44. This electrical circuit 35 defines a closed conductive path between battery 32 and light source 44 thereby energizing light source 44 when switch 36 is closed as depicted in FIG. 2. When the conductive path defined by electrical circuit 35 between battery 32 and light source 44 is opened by switch 36, as depicted in FIGS. 1 and 3, light source 44 is de-energized.
Switch 36 is a mechanically operated electrical switch which provides a flexure responsive circuit element in electrical circuit 35. In the embodiment of FIGS. 1-3, switch 36 opens and closes as the user's hand 24 is moved between a grasping shape 24a (FIG. 1) and a relatively outstretched shape 24b (FIG. 2). When the user's hand 24 is in a grasping shape 24a, such as when the user is grasping the handlebar of a bicycle, glove 22 is similarly positioned in a grasping configuration 22a (FIG. 1). When the user repositions his hand 24 in a relatively outstretched shape 24b, such as when the user is signaling a turn while riding a bicycle, glove 22 will be correspondingly repositioned in an outstretched configuration 22b (FIG. 2).
Electrical switch 36 is mounted on glove 22 at a position where it will be subject to flexure as the user's hand is moved between outstretched and grasping positions. Placement of switch 36 proximate one of the joints of the user's hand will subject electrical switch 36 to the desired flexure. For example, positioning switch 36 on a portion of glove 22 which envelopes one of the user's fingers 30 will generally subject switch 36 to a sufficient amount of flexure.
In the illustrated example, the entirety of switch 36, including patch 38, is positioned on a portion of glove 22 (i.e., that portion of glove 22 overlaid by patch 38 as seen in FIGS. 1 and 2), which envelopes a single finger 30 of the user. In the illustrated example switch 36 is mounted on that portion of glove 22 which envelopes the index finger of the user. Thus, the user can close and open switch 36 merely by flexing his or her index finger.
In the illustrated embodiment, switch 36 includes a flexible mounting patch 38 such as a relatively thick layer of polymeric material. Rigid electrical contacts 40 are secured to patch 38 at securement locations 42 by adhesives, tape, stitching or other suitable means. After securing contacts 40 to patch 38, patch 38 can be secured to glove 22 and wiring 34 can be conductively coupled to contacts 40. In its relaxed state, patch 38 will assume a generally planar shape and cause contacts 40 to engage providing a conductive path across switch 36. When patch 38 is stretched or bent, as shown in FIG. 1, contacts 40 will disengage thereby opening switch 36 and interrupting the conductive path. Alternative electrical switches may also be employed with the present invention. For example, conductors 40 could be located within an elastomeric tube to both prevent moisture from coming into contact with conductors 40 and provide a mounting structure for conductors 40.
With reference to FIGS. 1 and 2, it can be seen that switch 36 is mounted on glove 22 so that positioning glove 22 in a grasping configuration 22a places switch 36 in a shape 36a wherein switch 36 is open, and positioning glove 22 in an outstretched configuration 22b places switch 36 in a second shape 36b wherein switch 36 is closed. As used herein, a flexure responsive circuit element is a circuit element that responds to the flexing or stretching of the circuit element. For example, the illustrated electrical switch 36, which includes flexible mounting patch 38, and opens and closes in response to the flexing of patch 38 and thereby provides a flexure responsive circuit element. This allows the opening and closing of switch 36, and the resultant de-energizing and energizing of light 44, to be controlled by the user merely by changing the shape of the user's hand 24 which is located within glove 22 without requiring the direct manual manipulation of switch 36.
FIG. 4 provides a schematic diagram of a modified embodiment of the invention. In this embodiment, the light source is a light emitting diode (“LED”) 45 which is operably coupled with electrical power source 32 by electrical circuit 35. The embodiment of FIG. 4 also includes a flexure responsive circuit element 46. While the flexure responsive circuit element 46 in FIG. 4 could be a mechanically operable electrical switch similar to switch 36 in FIGS. 1-3, it may also take alternative forms.
The embodiment of FIG. 4 also includes a control circuit 48 which may take the form of a printed circuit board. Control circuit 48 is operably coupled with electrical circuit 35 and flexure responsive circuit element 46 whereby control circuit 48 selectively energizes and de-energizes light source 45 in response to operating characteristics of the flexure responsive circuit element 46. For example, circuit element 46 may be a “strain gauge” or similar device wherein circuit element 46 experiences a change in resistance in response to a change in its shape due to the flexure of the item of apparel 22 on which element 46 is mounted. The resistance of circuit element 46 would then be sensed by control circuit 48 which would then selectively energize or de-energize LED 45 in response to this sensed resistance of the flexure responsive circuit element 46. Alternative flexure responsive circuit elements that may also be employed include an electronic transducer for measuring flexion disclosed by Cimmino in U.S. Pat. No. 6,725,729 B1 which is hereby expressly incorporated herein by reference.
The various forms of flexure responsive circuit element 46 all experience a change in operating characteristics when subjected to a change in shape. In other words, circuit element 46 can be mounted on patch 38 or other suitable location on glove 22 such that when glove 22 is in a grasping configuration 22a, circuit element 46 will have one shape with a corresponding set of operating characteristics and when glove 22 is in an outstretched configuration 22b, circuit element 46 will have a different shape and a different set of operating characteristics. Control circuit 48 will sense the changeable operating characteristic and energize and de-energize LED 45 in response to the sensed, changeable operating characteristic of circuit element 46.
It is only necessary for one of the operating characteristics of circuit element 46 to vary, provided that such characteristic can be sensed by control circuit 48. For example, switch 36 conducts electrical current across the switch when closed and prevents the flow of electrical current when it is open while a strain gauge and other similar device experiences a change in its electrical resistance when subjected to a change in strain caused by a change of shape.
The use of a control circuit 48 in combination with a flexure responsive circuit element 46 rather than the use of only an electrical switch 36 provides a greater range of options in the operation of the light source. For example, control circuit 48 can be configured to energize LED 45 in multiple different modes of operation such as (a) an energized mode wherein the light source is continuously energized; (b) a de-energized mode wherein the light source is continuously de-energized; and (c) a flashing mode wherein the light source is repeatedly energized and de-energized.
The mode of operation is determined by the selective and repeated repositioning apparel item 22 between the first and second configurations 22a and 22b. It would be possible simply to toggle through the different modes of operation with each change in configuration 22a, 22b, however, with three modes of operation, this would not provide a consistent mode of operation for either of the apparel configurations 22a, 22b. Another possible method would be to return to a de-energized mode when the apparel items 22 is in configuration 22a with the energized mode being the result of a single repositioning of apparel item 22 from configuration 22a to configuration 22b and the flashing mode of operation resulting from two quick repositionings from configuration 22a to configuration 22b, e.g., within 2 seconds. Various other methods of controlling the actuation of the different modes of operation could also be employed with the present invention.
It is further noted that while the illustrated item of apparel 22 is a single glove, other forms of apparel may be employed with the present invention. For example, battery 32 could be mounted on a wrist band with flexure responsive circuit element 46 and control circuit 48 being mounted on one finger band and LED 45 being mounted on a separate finger band with wiring forming electrical circuit 35 extending between the various bands.
FIGS. 5 and 6 illustrate an alternative flexure responsive circuit element 136 that may also be used with the present invention. Circuit element 136 is a mechanically operated electrical switch and could be substituted for the electrical switch 36 in apparatus 20 illustrated in FIGS. 1-3 and which would allow a user to operate apparatus 20 as described above with reference to FIGS. 1-3.
As seen in FIGS. 5 and 6, circuit element 136 has a flexible mounting patch 138 that is mounted on apparel layer 22 to form layered structure 142. Mounting patch 138 is positioned at the same location as patch 38 on the index finger portion of apparel 22. As seen in FIGS. 5 and 6, mounting patch 138 is slit at its midpoint. Rather than mounting contacts and wiring on the top of patch 138, electrical contacts 140 and wiring 34 are embedded within mounting patch 138.
When circuit element 136 is positioned as shown in FIG. 5, the two halves of patch 138 are in registration and contacts 140 are in conductive engagement and provide a conductive path across element 136 and thereby energizing light 44. The shape of element 136 depicted in FIG. 5 corresponds to an outstretched configuration 22b of apparel 22. Layered structure 142 is flexed as apparel 22 is moved from an outstretched configuration 22b to a grasping configuration 22a. Flexure responsive circuit element 136 experiences a change in curvature and strain as apparel 22 is moved between configurations 22a and 22b and the shape of circuit element 136 shown in FIG. 6 corresponds to a grasping configuration 22a of apparel 22. When layered structure 142 is flexed as apparel 22 is placed in the grasping configuration 22a, circuit element 136 is bent as shown in FIG. 6 thereby separating contacts 140, opening the conductive path of circuit 35 and de-energizing light 44.
While this invention has been described as having an exemplary design, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles.
