Floor mat for collecting process particles and grounding the electrostatic charge
View Patent ↗A conductive floor mat is disclosed for collecting process particles and grounding the electrostatic charge accumulated on operators who stand on the mat. The conductive floor mat includes a frame assembly, a plurality of parallel spaced ribs, a plurality of parallel spaced supports and grounding wires. The frame assembly includes four frame members and a bottom surface. At least one of the four frame members has an angled top surface. Both ends of the ribs and supports are mounted to the opposite of the frame members. The supports are perpendicularly fixed to the ribs for increasing the supporting capacity thereon. The grounding wires are extending from the frame assembly to discharge the electrostatic charge accumulated on the operators.
1. A conductive floor mat disposed on an upper surface of a floor for collecting process particles and grounding an electrostatic charge, which comprises:
a conductive frame assembly disposed on the upper surface of the floor, the conductive frame assembly including four frame members and a bottom surface, in which at least one of the four frame members has an angled top surface;
a top surface comprising a plurality of parallel spaced conductive ribs in which both ends of the conductive ribs are mounted to opposite sides of the conductive frame assembly; and
grounding wires extending from the frame assembly for discharging the electrostatic charge,
wherein two of the frame members comprise hollow areas, and said two frame members are oppositely disposed, and the conductive ribs are connected between said two frame members.
2. The conductive floor mat of claim 1 , wherein the top surface consists essentially of the plurality of parallel spaced conductive ribs.
3. The conductive floor mat of claim 1 , wherein the hollow areas are sealed.
4. A conductive floor mat for collecting process particles and grounding electrostatic charge comprising:
a conductive frame assembly comprising four frame members and a bottom surface, the bottom surface comprising a board connected between the four frame members;
a top surface consists essentially of a plurality of conductive ribs mounted in parallel between first and second of the frame members; and
grounding wires extending from the frame assembly.
5. The conductive floor mat of claim 4 , wherein the conductive ribs are mounted above the bottom surface of the conductive frame assembly to define a space therebetween.
6. The conductive floor mat of claim 5 , further comprising a plurality of rigid supports disposed in parallel between the bottom surface of the conductive frame assembly and the conductive ribs for increasing the supporting capacity of the conductive ribs.
7. The conductive floor mat of claim 6 , wherein the rigid supports are fixed to the conductive ribs.
8. The conductive floor mat of claim 4 , further comprising a fixing button, the fixing button comprising a hole, wherein the grounding wires pass through the hole of the fixing button.
