HANDCART
Document Type and Number:
Japanese Patent JP2020147189
Kind Code:
A
Abstract:
To provide a handcart capable of improving operability during a leg closing action, by allowing the leg closing action to be performed only by a single action that is independent from the pushing force of a user with respect to a handle support post part in use.SOLUTION: An upper end portion of each rear wheel leg portion 12 is rotatably supported at a middle portion of each front wheel leg portion 11, and lower end portions of both leg portions 11 and 12 are coupled by a middle-foldable coupling frame 3. A rising/lying frame 24 rotatably provided near the upper end portion of each rear wheel leg portion 12 can be converted into a lying position and a rising portion. The coupling arm 36 is rotatably coupled to the rising/lying frame 24 and the coupling arm 3. An expansion/contraction member 39 is provided between a front side link 32 and a rear side link 34 of each coupling frame 3. Each front wheel leg portion 11 and each rear wheel leg portion 12 are converted from a leg opening position to a leg closing position through the coupling arm 36 and the coupling frame 3 with the conversion action of the rising/lying frame 24 from the lying position to the rising position, and is maintained at both positions by the contraction force of the expansion/contraction member 39.SELECTED DRAWING: Figure 2
