Problems solved by technology

[0010] Today it is increasingly felt that the prior art solutions only partially meet the need for using vehicles that are non-polluting, comfortable, safe, light in weight, easy to handle and especially capable of being operated with the smallest possible force, so that aging Humans can also use these vehicles

Embodiment Construction

[0027] Throughout the drawings, the same reference numbers are used to designate equivalent or functionally equivalent parts.

[0028] refer to Figure 1 to Figure 4 , the structure of the hand-propelled vehicle generally denoted by the reference number 11 comprises: a frame 13; a member 15 for controlling propulsion, which is associated with the frame 13 and arranged to be pushed by the driver's arm of the vehicle function to swing relative to the frame; the assembly 17, which is controlled by the control member 15, is used to convert reciprocating motion into circular motion; and the transmission assembly 19, which is used to transfer the The movement of the coupled drive shaft 21 is transmitted to a driven shaft 23 associated with a propulsion member, such as a wheel or a propeller, respectively, depending on whether the structure 11 is used for a land vehicle or a water vehicle.

[0029] According to the invention, the transmission assembly 19 comprises at least one trans...

Abstract

A hand propelled vehicle comprising a frame (13), a member (15) controlling the propulsion, associated with the frame (13) and arranged to oscillate relative to the frame due to the pushing action exerted by the arms of a vehicle driver, an assembly (17), controlled by said control member (15), for converting the reciprocating motion into a circular motion, and a transmission assembly (19) for transmitting the motion from a drive shaft (21) associated with said converting assembly to a driven shaft (23) associated with a propelling member, wherein said transmission assembly (19) includes at least one transmission shaft (25), perpendicular to the drive shaft (21) and the driven shaft (23) and kinematically connected to the drive shaft (21) and the driven shaft (23) through respective gears (27, 29).

Description

technical field [0001] The present invention relates to hand-propelled vehicles. [0002] More precisely, the invention relates to a vehicle whose propulsion is controlled by the force of the arm. Background technique [0003] To date, various types of vehicles capable of being operated by the force of the arms have been developed in order to meet the increasing market demand for pollution-free vehicles, as well as to meet the needs of people suffering from lower limb disabilities. [0004] GB 2 379 640 discloses, for example, a carrier for paraplegics having dual handles which control the rotation of a pair of rear wheels via a transmission assembly comprising a rod-crank linkage. [0005] US 3,895,825 discloses a two-wheeled vehicle in which a handle is provided which is associated with a swinging bar pivotally mounted on a tubular frame. The swing of the rod causes the rotation of the rear wheel through the transmission assembly including the rod-crank mechanism, and th...
