1. Field of the Invention
The present invention relates generally to accessories for tool boxes and tool bags. Particularly, the present invention relates to lighting accessories for a tool carrier.
2. Description of the Prior Art
Persons engaged in repair and construction type work ordinarily have to use a variety of hand tools to perform tasks. The worker often stores tools in a tool carrier, such as a tool bag, bucket, or tool box. In some cases, the tool carrier is a soft-sided tool bag with a flat bottom and soft, resilient or somewhat rigid sidewall. This type of tool bag is similar in shape to a 5-gallon plastic bucket commonly used in construction.
When tools are crowded into a tool carrier, it is often difficult to see the contents near the bottom of the tool carrier. The geometry of the carrier and the tool carrier being filled with tools allows only small amounts of light to reach the bottom of the carrier. To make matters worse, some tool carriers have a dark-colored finish material that absorbs light and many hand tools have a black grip or black finish. For example, one tool carrier available in the marketplace is a vinyl tool bucket with a carrying strap equipped with a carabiner. The tool bucket is finished in black vinyl and the straps and hardware have a black finish. One variation of the bucket includes a flexible vinyl neck portion at the top of the bucket that can be drawn closed. With the bucket open, the black vinyl finish and depth of the bucket result in a very dark space at the bottom of the bucket where it is difficult to see contents.
One approach to address this problem has been for the user to illuminate the inside of the tool carrier with a hand-held flashlight or headlight. Another approach has been to position the tool carrier so that light enters the bucket and illuminates the inside of the carrier. Yet another approach has been to clip onto the rim of the tool carrier a battery-powered light source, such as one having a flexible neck that can reach into the tool carrier. With such a light, the user switches on the light as needed and positions the light source to direct light into the inside of the carrier.
Unfortunately, the lighting solutions of the prior art fail to adequately address the difficulties of lighting a tool carrier loaded with tools. In particular, ambient light entering a tool carrier from above often does not reach the contents at the bottom of the carrier because it is blocked by the carrier itself and by its contents. Also, due to the dark-colored finish materials, light does not reflect off of inside surfaces of the carrier to illuminate the bottom of the carrier. Further, the flexible sidewall of some tool carriers folds or collapses on itself during use to result in a serpentine path for light to reach the bottom of the carrier. When the carrier is finished in black or dark colors, the sidewall absorbs light rather than reflecting it towards the bottom of the tool carrier.
Thus, it is common that even a bright flashlight or headlight will not sufficiently illuminate a tool carrier so that a worker can find smaller parts or tools at the bottom of the carrier. Additionally, even when a flashlight or headlight does shine into the tool carrier, the light from the flashlight or headlight is often blocked when the user's hand or arm reaches into the tool carrier, resulting again in a poorly illuminated or non-illuminated area of the tool carrier.
Therefore, what is needed is a lighting apparatus that illuminates the tool carrier from the inside and is sufficiently rugged to be used in a tool carrier filled with hand tools and the like. Accordingly, it is an object of the present invention to provide a lighting apparatus that illuminates the inside of a tool carrier. The present invention achieves these and other objectives by providing a combination of a tool carrier and a lighting apparatus for the tool carrier.
One aspect of the invention is directed to the combination of a tool carrier and a lighting apparatus for the tool carrier. In one embodiment, the conduit is constructed for removable installation in the tool carrier. In other embodiments, the conduit is being fixedly secured in the tool carrier as a permanent part of the tool carrier.
In one embodiment, the tool carrier had a floor and one or more sidewall extending upwardly from the horizontal floor to a carrier mouth, rim, or opening. A conduit made of a translucent or transparent material defines a conduit path between a first conduit end and a second conduit end. The conduit has a conduit path sized and shaped to extend along an inside perimeter of or across the floor of the tool carrier. Light sources are disposed in the conduit and distributed along the conduit path. A power source retained by the tool carrier is electrically coupled to the light sources.
In one embodiment, the lighting apparatus is built into or connected to the tool carrier. For example, the tool carrier is tool bag made of a pliable material. The conduit includes a flexible portion attached to and extending along the tool carrier sidewall to protect electrical leads connecting the power source and the light sources. The conduit is removable in some embodiments.
In another embodiment, an openable sleeve is installed over an end portion of the conduit and defines a compartment sized to retain the power source. For example, the openable sleeve is connected between the first conduit end and the second conduit end. In one embodiment, the openable sleeve is made of neoprene rubber or other pliable material and includes a hook-and-loop closure for access to the power source.
In another embodiment, the conduit includes a sidewall conduit extending upward along the sidewall of the tool carrier and having a lower end portion connected to the conduit. Electrical leads extend through the sidewall conduit to the light sources.
In another embodiment, the conduit includes a lighting floor member joined or directly connected to the conduit and extending across the floor of the tool carrier. For example, the lighting floor member is made of a material sufficiently translucent to diffuse light transverse to the lighting floor member. At least some of the light sources direct light into a perimeter edge of the lighting floor member to illuminate the lighting floor member.
In one embodiment, the conduit is made of crosslinked polyethylene tubing with an outer diameter of about ½ inch. In one embodiment, the light sources are LEDs on a length of LED strip lighting.
In some embodiments, the floor of the tool carrier has a circular shape. For example, the tool carrier is a plastic tool bucket or cylindrical tool bag made of a pliable material.
In another embodiment, a switch is operable on the tool carrier sidewall and is electrically coupled between the light sources and the power source. In another embodiment, the switch is a sensor switch operable between an off condition and an on condition in response to a stimulus such as a vibration, a change in lighting intensity, a detected motion inside the tool carrier, and a change in conductance, resistance or other electrical property. In another embodiment, the switch includes a timer circuit causing the switch to remain in an on condition for a predetermined length of time after being changed to the on condition from an off condition.

In one embodiment, conduit 110 is a length of cross-linked polyethylene (“PEX”) tubing with a round cross-sectional shape, an inner diameter of about ⅜″ (˜9.5 mm) and an outer diameter of about ½″ (−12.7 mm). PEX tubing is durable to provide protection to light sources 150 disposed in the tubing from the impact of tools or other objects dropped into a tool carrier, such as a tool bag or tool box, where lighting apparatus 100 is placed. Other materials and cross-sectional shapes of conduit 110 are acceptable. Acceptable materials include, for example, plastic or rubber such as clear silicone rubber, translucent polypropylene, and clear PVC. Acceptable cross-sectional shapes include round, square, rectangular, D-shape, and other shapes that define pathway 111 within the conduit of sufficient size to receive light sources 150. The material and cross-sectional shape may be selected based on the flexibility, durability, shaping ability, and translucence sought for a particular use.
In some embodiments, conduit 110 is a two-part conduit with a first conduit portion (e.g., a U-shaped portion) and a second conduit portion (e.g., a flat or U-shaped second portion), where first conduit portion mates with and combines with the second conduit portion to form a closed or substantially closed conduit 110. Examples of a two-part conduit include those used for cable and wire management, such as a hinged, rectangular raceway conduit or a corner race conduit with an L-shaped portion and an arced cover portion that attaches to the L-shaped portion.
In one embodiment, conduit 110 is formed, bent, assembled, or otherwise shaped so that conduit path 112 substantially follows a perimeter of a tool carrier floor 302 (shown in
Power source 200 provides electrical power to light sources 150. Power source may be a battery, battery pack, solar panel, or other AC or DC power source appropriate for light sources 150. Power source 200 is electrically connected to light sources 150 by one or more wires 202. In one embodiment, power source 200 is a 12V power source provided by one or more batteries. In another embodiment, power source 200 is an inductive power supply connected by coupling to the plurality of light sources 150. Power source 200 may be located outside of conduit 110 or may be disposed inside conduit 110.
Optionally, a switch 210 is connected between power source 200 and light sources 150. Switch 210 may be, for example, a toggle, rocker, plunger, push-button or other mechanically-operated switch; a sensor-controlled switch that opens and closes a circuit in response to detecting motion, vibration, light, a particular sound (e.g., a voice command, series of claps, or other repeatable sound), or a change in conductance, resistance, or other electrical property; or other switch. In one embodiment, switch 210 includes timer circuitry (not shown) so that light sources 150 illuminate for a predetermined length of time in response to activation by the user and/or sensing a condition. Of course, timer circuitry may be separate from switch 210 and connected as part of a circuit with light sources 150 and power supply 200. In yet another embodiment, switch 210 is a rollerball plunger switch. For example, a rollerball plunger-type switch 210 is installed in floor 302 of tool carrier 300 (shown in
In one embodiment, for example, power source 200 is a battery pack that is attached to or retained in a pocket or pouch on a tool bag with switch 210 on the battery pack or attached to the tool bag. In another embodiment, power source 200 is a plurality of watch batteries contained in conduit 110 and connected to switch 210 including a sensor. For example, switch 210 opens and closes in response to the user opening the tool carrier 300 or accessing the interior of the tool carrier 300. In one embodiment, tool carrier 300 includes a conductive fabric 317 (shown in

Similar to the embodiment of
One embodiment of conduit 110 is optionally attached to, formed with, or otherwise includes a lighting floor member 155 that extends across a region enclosed or substantially enclosed by conduit 110. In some embodiments, lighting floor member 155 is attached to and extends across a top end portion 110d or bottom end portion 110e of conduit 110. When attached to top end portion 110d, lighting floor member 155 provides a protective cover plate; when attached to bottom end portion 110e, lighting floor member 155 provides a bottom plate that may function both as a tray to catch small objects as well as providing a protective surface for the tool bag. When attached to conduit 110 at a location between top end portion 110d and bottom end portion 110e, lighting floor member 155 can serve both of these purposes. Also, when attached to conduit 110 between top end portion 110d and bottom end portion 110e and made of a translucent material, lighting floor member 155 can be illuminated by light sources 150. Lighting floor member 155 additionally is useful to provide structural support to conduit 110 to maintain its shape.
In one embodiment, for example, lighting floor member 155 connects to bottom end portion 110e of conduit 110 and extends across the region enclosed by or substantially enclosed by conduit 110 as illustrated in

In another embodiment, union connector 250 is a T-shaped union that directs wires 202 from conduit 110 to a sidewall conduit 316 defined in sidewall 306 or attached to sidewall 306. For example sidewall conduit 316 is defined by a fabric strip stitched to sidewall 306 and extending partially or completely along sidewall 306 from floor 203 to rim 318 of tool carrier 300. In one embodiment, sidewall conduit 316 extends part way towards rim 318 to an opening (not shown) in sidewall 306 for wires 202 to connect to power supply 200 and/or switch 210 located on outside surface 310 of tool carrier 300.
In another embodiment, wires 202 exit conduit 110 or union connector 250 and travel along sidewall 306 to power supply 200 and/or switch 210. For example, wires 202 are protected by a cavity in sidewall 306, by a sidewall conduit 316 made of fabric or pliable material, or by being stitched to sidewall 306 between power source 200, switch 210, conductive fabric 317, and or other components as needed.
In use, embodiments of lighting apparatus 100 may be installed in tool carrier 300 to illuminate the bottom of the tool carrier. When lighting apparatus 100 is separate from tool carrier 300, the user installs lighting apparatus 100 in tool carrier with conduit 110 against floor 302 of tool carrier 300, such as extending along the perimeter 304 of floor 302 and abutting sidewall 306. In some embodiments, lighting apparatus 100 is installed in a temporary or removable fashion. In other embodiments, lighting apparatus 100 is permanently or semi-permanently installed in tool carrier 300, or provided in combination with tool carrier in a pre-assembled form, such as when wires 202, power source 200, switch 210, and/or other components are attached to, extend through, or are integrally connected with tool carrier 300. When switch 210 is provided, the user closes switch 210 to turn on light sources 150 and illuminate the interior of tool carrier 300. When conductive fabric 317 is provided, the user contacts conductive fabric 317 to close switch 210 and illuminate light sources 150. Power source 200 is charged, updated, or replaced as needed to provide electrical power to light sources 150.
