| 摘要 |
A telescopic stick foldable in two portions (100), to be used for hiking, downhill skiing, cross country skiing, is made up of at least four tubular portions: an upper telescopic tubular part (200) provided with a grip (60), a first intermediate telescopic tubular part (300), a second intermediate telescopic tubular part (400), the telescopic parts sliding one in the other and fixable in position by locking elements, and a lower tubular part (500) terminating with a pointed end (1) connected to the second intermediate part adjacent to it. The lower tubular part (500) is restrained to the remaining parts by a rope (2) which traverses at least the second intermediate part (400), so that the stick can be folded in two parts, bringing the telescopic parts into a position of minimum extension and folding the lower part (500) on the others after having released it from the adjacent intermediate part. |

1. A foldable telescopic stick (100), comprising:
locking elements (10, 10′); at least four tubular portions including an upper telescopic tubular part (200) provided with a grip (60), a first intermediate telescopic tubular part (300), a second intermediate telescopic tubular part (400), and a lower tubular part (500), said upper, first intermediate, and second intermediate telescopic parts (200, 300, 400) being slidable one in the other and fixable in position by the locking elements (10, 10′), said upper, first intermediate, and second intermediate telescopic parts (200, 300, 400) being i) retractable into a telescopically closed position of minimum extension, and ii) extendable into a fully extended position of maximum extension, the lower tubular part (500) being releasably and foldably connected to said second intermediate telescopic part (400) wherein the lower tubular part is extended into a fully extended position, and released from and folded with the second intermediate telescopic parts into a folded condition, a pointed end (1) terminating the lower tubular part (500); a plug (4) located on an upper end of said first intermediate part (300), the plug including a hollow cylindrical seat; a rope (2) extending from said lower tubular part (500) and internally traversing at least said second intermediate part (400) and said plug (4), said rope (2) restraining said lower tubular part (500) to the first intermediate and second intermediate telescopic parts (300, 400) so that said stick (100), when in said telescopically closed position, folds into two parts only, the two parts consisting of i) the telescopically closed upper, first intermediate, and second intermediate telescopic parts (200, 300, 400) in the position of minimum extension, and ii) said lower part (500), with the telescopically closed upper, first intermediate, and second intermediate telescopic parts (200, 300, 400) in the position of minimum extension being located adjacent to and alongside the lower part (500), the lower part (500) being released from the adjacent intermediate part (400); and a shank (3) restraining said rope (2) to said first intermediate part (300), the shank (3) slidable along the rope (2) which goes to abut in the hollow cylindrical seat of the plug (4) located on the upper end of said first intermediate part (300). |
