Abstract

DC60 (01/09/57) The improved folding mast's pivot point connecting the upper and lower mast sections consists of an upper mast (10) and a lower mast (20) whose contact flanges act as the folding pivot points. The upper mast (10) and lower mast (20) are connected to a pivot shaft (17) for folding support. The contact flanges consist of upper plates (11) and lower plates (21) with diameters larger than the diameter of the upper mast body (10) and lower mast body (20). Part of the upper plate (11) and lower plate (21) contain the first pivot ring (31), the second pivot ring (32), the third pivot ring (33), and the fourth pivot ring (34), which act as the pivot points. With the large locking bolt (30) on the upper arm (22) and lower arm (26) connected to the rocker shaft (17), it is connected to the body of the upper post (10) and lower post (20), respectively, in a manner that makes an angle of at least 20-80 degrees and has a length equal to or greater than half the length of the rocker shaft (17). The improved folding post, with the rocker section connecting the upper and lower posts, consists of the upper post (10) and the lower post (20) at the contact flange between them, which will be the folding pivot point. The upper post (10) and lower post (20) are connected to the rocker shaft (17) for support of the folding rotation. The contact flanges between the upper (11) and lower (21) plates, which have a diameter larger than the diameter of the upper (10) and lower (20) body sections, are located on the upper (11) and lower (21) plates. The first (31) and second (32) pivot rings, the third (33) and the fourth (34) pivot rings, serve as pivot points for the rocking section, attached to the large locking bolt (30) on the upper (22) and lower (26) arms. The rocking shaft (17) is connected to the upper (10) and lower (20) body sections, respectively, in a manner that makes at least 20-80 degrees. Its length is equal to or greater than half the length of the rocking shaft (17).

Claims (1)

1. The improved folding post with a rocking mechanism connecting the upper and lower post sections consists of an upper post (10) and a lower post (20). The contact flange between the upper post (10) and lower post (20) serves as the pivot point for folding the upper post (10) down. A portion of the upper post (10) and lower post (20) are connected to a rocking shaft (17) to support the folding of the upper post (10). The special feature is that The lower end of the upper pole (10) and the upper end of the lower pole (20) are comprised of the upper plate (11) and the lower plate (21), respectively. The upper plate (11) and the lower plate (21) serve as contact flanges between the upper pole (10) and the lower pole (20). The upper plate (11) and the lower plate (21) have diameters larger than the diameter of the upper pole body (10) and the diameter of the lower pole body (20), respectively. Part of the upper plate (11) contains the first pivot ring (31) and the second pivot ring (32), which serve as pivot points for the rocking section. Part of the lower plate (21) contains the third pivot ring (33) and the fourth pivot ring (34), which serve as pivot points for the rocking section. The first pivot ring (31), the second pivot ring (32), the third pivot ring (33), and the fourth pivot ring (34) It will be assembled with the large locking bolt (30).
