专利汇可以提供Lighted work mat专利检索,专利查询,专利分析的服务。并且A modular work mat for a vehicle including a base, a plurality of light sources embedded in the base, wiring connecting the light sources; wherein the wiring is operatively connectable to a power source. The light sources preferably are LEDs. The base includes a first layer of a first material and a second layer of a second material and the LEDs are embedded between the first and second layers. The mat is connected via a power cord to a power supply and when the power supply is activated, the LEDs emit light through the first layer of the base. The work mat is placed on a surface so that the emitted light is able to illuminate a portion of the undercarriage or the entire undercarriage. The mat may be positioned beneath a portion of the vehicle's undercarriage or the vehicle may be driven onto the mat.,下面是Lighted work mat专利的具体信息内容。
The invention claimed is:
1. Technical Field
This invention relates generally to work mats. Specifically, this invention is directed to work mat having a base in which a plurality of LED's are embedded, and where the mat is positionable on a surface beneath the undercarriage of a vehicle; and the LEDs are activate to illuminate the vehicle's undercarriage from below.
2. Background Information
Mechanics and people skilled in personally working on their own vehicles require adequate lighting to see clearly when they are working on a vehicle. If the mechanic is working on a vehicle's engine, it is possible to position a light source in a location that enables the mechanic to see. That light source may simply be overhead lights in the garage, a flashlight of some type, or a work light that is secured somehow onto the underside of the vehicle's hood or adjacent the part of the engine the mechanic is working on.
If, however, the mechanic is working on the vehicle's undercarriage and does not have access to a lighted work pit, the mechanic may need to lie on the ground, slide under the vehicle and use a flashlight to see. This, of course, causes issues because of the need to hold the flashlight. Additionally the light source is a point light source and thus casts shadows which interfere with the mechanic's ability to work properly.
There is therefore a need in the art for an improved light source for providing illumination for locations such as under the undercarriage of a vehicle.
The device of the present invention comprises a modular lighted work mat made up one or more substantially flat modular panels. Each panel includes a plurality of light-emitting diodes (LEDs) embedded in a base and spaced at intervals from each other. The lighted work mat is provided with wiring to connect the LEDs and the wiring is operatively connected to a power source. A switch is provided on the work mat to activate and deactivate the LEDs. Multiple lighted work mat panels are joined together along their edges by suitable fasteners so that the mat may be made to a desired size so as to provide lighting for the entire underside of a vehicle. Panels are added or removed to adjust the size of the lighted work mat for different vehicles. A ramp may be connected to one edge of the lighted work mat to enable a mechanic's creeper to roll onto and off of an upper surface of the lighted work mat.
A preferred embodiment of the invention, illustrated of the best mode in which Applicant contemplates applying the principles, is set forth in the following description and is shown in the drawings and is particularly and distinctly pointed out and set forth in the appended claims.
Similar numbers refer to similar parts throughout the drawings.

Referring now to
First layer 24 has first and second edges 24a, 24b (
First layer 24 preferably comprises a planar sheet of transparent or opaque material. First layer 24 preferably is a single solid sheet of material that extends substantially the entire length “L” (
Suitable materials for first layer 24 of the base include sheets of acrylic materials such as those sold under the trademark Plexiglas® fabricated by Arkema of Colombes, France, or gels that solidify into sheets of transparent or opaque material. The transparent or opaque nature of first layer 24 permits light 22 to pass through first layer 24 when switch 20 is activated, as will be hereinafter described. First layer 24 may be rigid or flexible in nature. The first layer 24 preferably is additionally of a sufficient strength and durability to withstand a mechanic's creeper or a vehicle rolling back and forth across the same multiple times.
Second layer 26 preferably is fabricated from materials such as rubber or plastic. Any other suitable material may be used without departing from the scope of the present invention. It will be understood that if second layer 26 is fabricated from plastic it may also be transparent or opaque so that light may shine therethrough. If this is the case then work mat 10 may be used with either of the first and second layers 24, 26 contacting surface 14.
Second layer 26 may also be rigid or flexible in nature and of sufficient strength and durability to support the weight of a mechanic and a mechanic's creeper, or a vehicle. Second layer 26 includes a generally horizontal, planar region 28 that is disposed substantially parallel to first layer 24 and extends for substantially the entire length “L” and width “W” of work mat 10. Second layer 26 further includes a plurality of rows of upstanding first walls 30 and a plurality of rows of upstanding second walls 32. First walls 30 and second walls extend outwardly from region 28 and generally at right angles thereto. Furthermore, the rows of first walls 30 are spaced a distance apart from each other and are generally parallel to each other. The first walls 30 preferably as also disposed generally at 45 degrees to first and second edges 26a, 26b and first and second ends 26c, 26d. The rows of second walls 32 are spaced a distance apart from each other and are disposed parallel to each other. The rows of second walls 32 intersect the rows of first walls 30. The rows of second walls 32 are disposed at right angles to the rows of first walls 30 and are oriented generally at 45 degrees to first and second edges 26a, 26b, and first and second ends 26c, 26d. Thus, the rows of first and second walls 30, 32 form a grid that extends outwardly from region 28. As indicated in
A plurality of compartments 34 is defined and bounded by portions of first layer 24, region 28 and pairs of adjacent first walls 30 and pairs of adjacent walls 32 in each of the mat shown in
In accordance with the present invention, work mat 10 includes a plurality of light sources which are embedded in the base. The light sources preferably are light emitting diodes (LEDs) 36. Each LED is located inside its own compartment 34 in the base. The wiring 15 extends through region 28 of second layer 26 and operatively connects the LEDs 36 to power cord 16. If first layer 24 is fabricated from a gel, the LEDs 36 will be installed on second layer 26 and connected to wiring 15 and the liquid gel material will be poured over second layer 26, covering the LEDs 36. Then, when the liquid gel material solidifies, the compartments 34 will be full of the solidified and hardened gel material and the LEDs 36 will be surrounded and covered by the solidified and hardened gel material. In either instance where first layer 24 is an acrylic sheet or a hardened gel layer, first layer 24 acts as a transparent shield for the LEDs 36.
Work mat 10 is used in the following manner. Vehicle 12 stands on surface 14. The mechanic will place second layer 26 of mat 10 on surface 14 and slide mat 10 underneath vehicle 12 in the manner represented by arrow “A” (
Referring to
Frame 154 preferably is a generally rectangular member that is made from a metal such as a heavy-duty steel. (It will be understood that frame 154 and therefore work mat 110 may be fabricated to any other desired shape. Frame 154 has a first edge 154a, a second edge 154b, a first end 154c and a second end 154d that are connected together to define and bound an interior cavity 158. One or more panels 152 are received in interior cavity 158 are engaged with frame 154. Each of the first and second edges 154a, 154b and first and second ends 154c, 154d of frame 154 is made from one or more metal bars. In
In accordance with a specific feature of the present invention, frame 154 includes a plurality of fastener members 160 which extend into cavity 158. Each fastener member 160 is configured to be received within a complementary recess 162 defined in one of panels 152. In a similar fashion, each panel 152 has a perimeter made up from pairs of spaced-apart opposing edges 152a, 152 (
