发明名称 FOLDING SAWHORSE
摘要 FOLDING SAWHORSE A sawhorse has a T-shaped beam with two brackets secured to the beam adjacent its opposite ends. Legs are pivotally mounted on the brackets to pivot between extended positions projecting downwardly and sloping outwardly to the side and to the end of the beam and retracted positions lying along the underside of the top plate of the beam. The brackets are U-shaped sheet metal brackets that have support flanges at the top ends of their arms. The base of the bracket and the support flanges are connected to the vertical web of the main beam, while the top plate of the beam is also fastened to the support flanges. Locking pins are carried by the brackets to lock the legs in their extended and retracted positions. The pins are preferably adjustable.
