  "abstract": "A pivoting leg assembly (10) for a sawhorse, the leg assembly comprising: a pair of pivotally movable leg members (40), the leg members movable between a storage position and operative position; a mounting body (50) for mounting the pair of leg members, the mounting body including a bridging member (70), a first support portion (80) having two first arms (82), and a second support portion (90) having two second arms (92); the bridging member extending between the two first arms; the second arms located within the first arms to form a gap between each respective first arm and second arm; wherein each leg member is pivotally mounted to at least one of the arms and sandwiched between a respective first arm and second arm within the gap.",
  "claims": [
    "1. A pivotal leg assembly for a sawhorse, the leg assembly comprising: a pair of pivotally movable leg members, said leg members movable between a storage position and operative position; a mounting body for mounting said pair of leg members, said mounting body including a bridging member, a first support portion having two first arms, and a second support portion having two second arms; said bridging member extending between said two first arms; said second arms located within said first arms to form a gap between each respective first arm and second arm; wherein each leg member is pivotally mounted to at least one of said arms and sandwiched between a respective first arm and second arm within the gap.",
    "2. The pivotal leg assembly of claim 1, wherein the bridging member, first support portion and second support portion are integrally formed.",
    "3. The pivotal leg assembly of claim 1, wherein the bridging member, first support portion and second support portion are separate units.",
    "4. The pivotal leg assembly of claim 3, wherein the bridging member is attached to the first support portion.",
    "5. The pivotal leg assembly of claim 4, wherein the bridging member comprises a bridging web having two forward extending plates.",
    "6. The pivotal leg assembly of claim 4, wherein the bridging member comprises a bridging plate.",
    "7. The pivotal leg assembly of claim 1, wherein the first support portion is a first support bracket.",
    "8. The pivotal leg assembly of claim 7, wherein the first support bracket comprises a first web having two first depending side plates.",
    "9. The pivotal leg assembly of claim 1, wherein the second support portion is a second support bracket.",
    "10. The pivotal leg assembly of claim 9, wherein the second support bracket comprises a second web having two second depending side plates.",
    "11. The pivotal leg assembly of claim 1, wherein each leg member is pivotally mounted to both of said arms.",
    "12. The pivotal leg assembly of claim 1, wherein each leg member abuts both of said arm members.",
    "13. The pivotal leg assembly of claim 1, wherein the width of the gap is commensurate in size with the width of the leg member.",
    "14. The pivotal leg assembly of claim 1, including a locking mechanism to lock the leg members in at least the operative position.",
    "15. The pivotal leg assembly of claim 14, wherein the locking mechanism may include an engagement member to engage the leg.",
    "16. The pivotal leg assembly of claim 15, wherein the engagement member is a pin, tab, or clasp.",
    "17. The pivotal leg assembly of claim 14, wherein the locking mechanism is attached to the bridging member.",
    "18. A sawhorse comprising a cross member attached to two pivotal leg assemblies, each pivotal leg assembly comprising: a pair of pivotally movable leg members, said leg members movable between a storage position and operative position; and a mounting body for mounting said pair of leg members, said mounting body including a bridging member; a first support portion having two first arms and a second support portion having two second arms; said bridging member extending between said two first arms; said second arms located within said first arms to form a gap between each respective first arm and second arm; wherein each leg member is pivotally mounted to at least one of said arms and sandwiched between a respective first arm and second arm within the gap.",
    "19. The sawhorse of claim 18, wherein each pair of legs are pivotally mounted to different points on each of the pivotal leg assemblies.",
    "20. The sawhorse of claim 18, wherein the cross member has a top surface with two depending side surfaces.",
    "21. The sawhorse of claim 18, wherein at least one slot is located within the top surface.",
    "22. The sawhorse of claim 18, wherein the cross member is a channel.",
    "23. The sawhorse of claim 18, wherein the cross member is a beam.",
    "24. The sawhorse of claim 18, wherein each pivotal leg assembly includes a locking mechanism to lock the leg members in at least the operative position.",
    "25. The sawhorse of claim 24, wherein the locking mechanism is operated from an end of the sawhorse.",
    "26. The sawhorse of claim 18, wherein the cross member forms at least part of the first support portion.",
    "27. A trestle comprising at least one board attached to two sawhorses, each sawhorse comprising a cross member attached to two pivotal leg assemblies, each pivotal leg assembly comprising: a pair of pivotally movable leg members, said leg members movable between a storage position and operative position; and a mounting body for mounting said pair of leg members, said mounting body including a bridging member; a first support portion having two first arms and a second support portion having two second arms; said bridging member extending between said two first arms; said second arms located within said first arms to form a gap between each respective first arm and second arm; wherein each leg member is pivotally mounted to at least one of said arms and sandwiched between a respective first arm and second arm within the gap.",
    "28. The trestle of claim 27, wherein the sawhorse has at least one slot located in the cross member to attach the board.",
    "29. The trestle of claim 27, wherein a plug is positioned within the slot to join the board to the sawhorse."
