高さ調整機構。(1) A mechanism for adjusting the height of the handle of a handcart, consisting of an upper part having a handle, and a lower bar part that overlaps the upper part and supports the upper part in a vertically slidable manner. The lock hole is made up of a plurality of lock holes formed in the wall of the lower bar portion and aligned in the vertical direction at predetermined intervals, and a communication passage that connects each of the lock holes located above and below with each other. The connecting passage has a width smaller than the width of the lock hole, and the connecting passage has a width that is smaller than the width of the lock hole, and the connecting passage has a width that is smaller than a width of the lock hole, and a wall of the upper rod portion that overlaps with a wall of the lower rod portion is provided in a direction perpendicular to the wall surface. The locking rod further includes a locking rod that is slidably attached and has a shaft that passes through the adjustment link, and the shaft of the locking rod has a width larger than the width of the communication passage and is engaged with the lock hole. and a small diameter portion having a width large enough to pass through the communication passage, and when the large diameter portion of the lock rod is located in the lock hole, the upper diameter portion A handle height adjustment mechanism for a handcart, wherein sliding is prohibited and when the small diameter portion of the lock rod is located within the adjustment hole series, sliding of the upper part is allowed. (2) The lock rod is always biased by a spring so that the large diameter portion of the lock rod slides back to the position within the adjustment hole series.
A handle height adjustment mechanism for a handcart as set forth in claim 1 of the utility model registration claim.
