TH9545C3 - The improved folding column rocker section connects the top section and Mast bottom section - Google Patents

Abstract

DC60 (01/09/57) Improved folding column, the rocker section connects the top and bottom columns, consisting of the top (10) and the bottom (20) columns on the flange. The contact between each other is the pivot point, the upper column (10) and the lower column (20) are connected to the rocker shaft (17) for supporting the folding rotation. The contact flanges are composed of the top plate (11) and the bottom plate (21) larger than the diameter of the upper column (10) and the lower column ( 20) One section, the top pivot ring (11) and the lower keypad area (21), consists of the first pivot ring (31), second pivot ring (32), third pivot ring (33), and point ring. The fourth (34) pivot serves as the pivot section of the rocking. By assembling With the large mounting bolts (30) on the upper arm (22) and the lower arm (26) attached to the rocker shaft (17), they are connected to the body of the upper column (10) and the lower column ( 20) respectively in the manner in which degrees are made At least 20-80 degrees and the length. Equal to half or greater than the length of the rocker shaft (17) Improved folding mast section connects the top and bottom columns. It consists of the top section (10) and the bottom section (20) where the flanges are in contact with each other, the top section (10) and the bottom section (20) are connected to the rocker shaft ( 17) for supporting rotation and folding The spaced contact flanges consist of the top plate (11) and the bottom plate (21) with a larger center diameter than the upper pole body diameter (10) and The lower body of the column (20), one part of the upper pivot (11) and the lower pivot area (21), consists of the first pivot point (31) and the second pivot ring (32). The third (33) and the fourth (34) pivot loop act as the pivot point of the rocking part. By assembling With the large mounting bolts (30) on the upper arm (22) and the lower arm (26) attached to the rocker shaft (17), they are connected to the body of the upper column (10) and the lower column ( 20) respectively in the manner in which degrees are made At least 20-80 degrees in length. Equal to half or greater than the length of the rocker shaft (17)
