Abstract

The utility model belongs to the technical reconstruction for the structures of the saddle and the handle bar of a civil small tricycle. The saddle of the small tricycle is changed into seats (1), (2), and (3) which are respectively provided with a back rest and a damping device, and the original saddle is saved. The seats are fixed at the back lower part of the original saddle. A handle bar (7) and a front fork pipe are moved to the positions (4) and (9) backwards. The middle part of the original handle bar and a front fork pipe are reserved. The structure of the middle part of the utility model is that steering rods (6) and a universal joint (5) are connected to form a trapezoid or parallelogram mechanical linkage device which uses a front and a back handles (4) and (7) as the bottom, and uses two steering rods (6) as the waist. The direct steering of the original handle bar is changed into the indirect steering, which causes the persons in middle and old age to ride conveniently, safely, comfortably, and easily.

Description

Saddle steering gear for small tricycle specially adapted for middle and old aged person

The utility model belongs to the technological change to civilian kiddie car vehicle seat and handle bar structure.

The purpose of this utility model is the handicapped profit of middle-aged and old shanks, movement response is slow, and sliding, snow, rain, get on the bus, get off in the road, it is injured to fall down easily, rides for a long time easily to make big forearm and buttocks muscles fatigue impaired, for addressing the above problem the special the design that proposes.

The purpose of this utility model is achieved in that the seat that the vehicle seat of civilian little three-wheel is changed into backrest and shock absorption device, with former vehicle seat cancellation.Seat is installed in the appropriate location, the back lower place of former vehicle seat position.To move to appropriate location, former handlebar rear behind the handlebar (containing the front fork tube device), former handlebar keeps the centre portion of its front fork tube and handlebar.After move breeches pipe and former breeches pipe at vertical plane surface planted agent keeping parallelism, after move handlebar and link with former handlebar centre portion by deflecting bar and universal knot (or chain and horizontal sprocket wheel).Make former handlebar with after move handlebar and can turn to synchronously.Move handlebar after promptly rotating, former handlebar centre portion rotates thereupon in the same way.After being actually, moves said apparatus handlebar and former handlebar centre portion is the end, with two deflecting bars mechanical linkage that is the trapezoidal or parallelogram of waist.With original directly turn to become indirectly turn to.By the trapezoidal or parallelogram plane that front and back handle and deflecting bar form, can fix the optional position of the exposed portions serve of pipe in front and back.Plane after the displacement should be parallel with primary plane.Because of after move handlebar structure fully for after move the seat service, so they are indivisible integral body.

Existing little three-wheel is owing to vehicle seat position height, and the handlebar position is low, and it is very inconvenient that the elderly is got on or off the bus, and ride National People's Congress's forearm, waist, buttocks muscles are in tension always by bike the time.Ride for a long time and easily make muscular fatigue impaired.Center of gravity height in addition, shakiness is also dangerous.Improved little three-wheel, vehicle seat changes seat into, makes cyclist's arm, waist and buttocks comfortable.Seat moves down, and center of gravity also moves down.The people that rides gets on or off the bus and very makes things convenient for stability and safety.It is lower slightly to move the aspect ratio people's shoulder of riding behind the handlebar.The big forearm of both hands handle is comfortable.When riding, the elderly can loosen by whole-body muscle.Ride for a long time indefatigability, very safe ready.And can entrust my old man, and other article, being suitable for very much middle-aged and old enure healths, short distance shopping and short-distance tourism are ridden.The design's sample car is ridden through examination in a year and is reached design goal fully.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof:

This apparatus body is by seat and turn to handle to form.Seat is made up of damping spring (1) seat cushion (2) backrest (3).Turn to by after move and move that the former handlebar centre portion of breeches pipe (9) (7) is former forms pipe (13) former front fork tube (10) universal knot (or horizontal sprocket wheel) (5) deflecting bars (or chain) (6) moving behind the pipe (12) behind the handlebar (4).

Owing to move behind the seat (1) (2) (3), can only will move behind the handlebar for ease of steering operation, change and directly turn to turning to indirectly.Owing to front and back are positioned at pipe (13) (12) at the mid point of going to the bottom on the trapezoidal or parallelogram of front and back handle and two deflecting bar formation.Go to the bottom (4) so rotate, upper base (7) can be done to rotate in the same way synchronously with going to the bottom, and reaches the purpose that turns to indirectly.

Realization of the present utility model, because simple in structure, member is easy to processing, cost is low, does not have any technical barrier for maker.

Claims

1, the seat steering hardware of the little three-wheel of a kind of person in middle and old age, it is characterized in that seat is made up of shock absorption device (1) cushion (2) backrest (3), its position places the back lower place of the former vehicle seat of little three-wheel, turn to by after move the preceding handlebar tube of the former handlebar centre portion of the universal knot of handlebar (4) (5) (7) (13) rear bar pipe (12) front fork tube (10) back breeches pipe (9) deflecting bar (6) and form, after move handlebar and place former handlebar rear position.

2, press the seat steering hardware of the little three-wheel of the described a kind of person in middle and old age of claim 1, it is characterized in that turning to rear bar before coming down to is the end, two deflecting bars are the mechanical linkage of the trapezoidal or parallelogram of waist, and this trapezoidal or plane, parallelogram place can be fixed a pipe exposed portions serve optional position, (13) (12) in front and back.Plane after the displacement should be parallel with primary plane.

3, by claim (1), the little three-wheel seat of (2) described a kind of person in middle and old age steering hardware, handle is to be connected with universal knot by deflecting bar before and after it is characterized in that.
