Abstract
Abstract A conveying tool comprises a funnel-shaped hopper and a tubular conveying part connected to the bottom of and hanging downward from the hopper, the conveying part comprising one unit section or a plurality of unit sections detachably connected end-to-end, each unit section comprising a pair of opposed and spaced-apart, rectangular main sheets and a pair of opposed rectangular side sheets with vertical edges secured to respective vertical edges of the main sheets thereby to form a tubular structure. The main sheets possess elasticity and flexibility and have, on the inner surfaces thereof, a large number of elastic projecting members, and the side sheets possess flexibility and are more pliable than the main sheets. Picked fruit dropped into the hopper are braked in their descent by the elastic projecting members and the inner wall surface of the conveying part and are thereby slowly lowered without damage to a container on the ground or on a vehicle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
A speed-slowing conveying tool for lowering fruit or the like from a high place to a lower place without damage thereto, said conveying tool comprising a hopper to be positioned at said high place and tubular conveying means connected at its upper end to the bottom of the hopper and extending downward toward said lower place, the conveying means comprising a pair of opposed and spaced-apart main sheets of rectangular planar shape with vertical edges and a pair of opposed side sheets of rectangular planar shape with vertical edges respectively secured to said vertical edges of the main sheets thereby to form a tubular structure, the main sheets possessing elasticity and flexibility and having on the inner surfaces thereof a large number of distributed elastic projecting members, the side sheets possessing flexibility and being more pliable than the main sheets.
Claim 2
Dependent Claim
140 words
A speed-slowing conveying tool for lowering fruit or the like from a high place to a lower place without damage thereto, said conveying tool comprising a hopper to be positioned at said high place and tubular conveying means connected at its upper end to the bottom of the hopper and extending downward toward said lower place, the conveying means comprising a pair of opposed and spaced-apart main sheets of rectangular planar shape with vertical edges and a pair of opposed side sheets of rectangular planar shape with vertical edges respectively secured to said vertical edges of the main sheets thereby to form a tubular structure, the main sheets possessing elasticity and flexibility and having on the inner surfaces thereof a large number of distributed elastic projecting members, the side sheets possessing flexibility and being more pliable than the main sheets.
Claim 3
Dependent Claim
