Abstract

PROBLEM TO BE SOLVED: To solve such the problem that, although a tricycle of two front wheels and a single rear wheel drive is a stable vehicle and is a stable vehicle which is free from falling down and does not need a stand, the tricycle can not cope with centrifugal force upon the turning.SOLUTION: The swing device is configured such that in the right and left wheels 4 move up and down in an opposed direction to each other like a weighing scale, and front connection holes on right and left ends of a T-shape connection bar 17 and rear connection holes on the upper side of forks 14 are penetrated by connection bolts. Both front wheels 4 are supported by the forks 14 and the connection bolts, the center of the T-shape connection bar 17 is supported by a central shaft, the central shaft is fixed to a front link 1 and the front wheels 4 are held on the middle of the vertical movement. The central shaft is fixed to the front link 1, and the front wheels 4 perform vertical movement respectively in accordance with right and left movement of the T-shape connection bar lower end by means of combination sliding between the T-shape connection bar lower end and a swing roller.

Description

Detailed Description of the Invention

本発明は前二輪、後輪駆動の三輪車の「スイング」装置にて関するもので、前リンク（１）と後リンク（２）が垂直の「リンクピン」（３）で結合され、一本の「リンク」となり、「リンクピン」の直角方向に左右に折れ曲がり、子供席（６）上の「ハンドル」（７）の操作で、前輪（４）が上下に天秤の様に交互に連動するものである。The present invention relates to a “swing” device for front two-wheel and rear-wheel drive tricycles, wherein the front link (1) and the rear link (2) are connected by a vertical “link pin” (3), "Link", which bends right and left in the direction perpendicular to the "link pin", and operates the "handle" (7) on the child seat (6) so that the front wheels (4) are interlocked alternately like a scale up and down It is.

三輪車は三点支持である為転倒する事はない乗り物であるが為め、「スイング」が出来ない乗り心地の悪い乗り物でもある。The tricycle is a three-point support vehicle that does not fall down, but it is also a poorly comfortable vehicle that cannot swing.

一般に三輪車とは前一輪車の自転車と、後二輪を組み合わせ、一本車体の三輪車で、後二輪は車体に固定される為、三点支持となり「スイング」の出来ない乗り物である。In general, a tricycle is a single-wheeled tricycle that combines a front unicycle bicycle and a rear two wheels, and the rear two wheels are fixed to the vehicle body.

後輪の単輪駆動でもあり、「カーブ」では不都合である。又運転者の後部に荷物席があり、子供の乗車は見張りが充分でない乗り物である。This is also a single-wheel drive for the rear wheels, which is inconvenient for “curves”. There is a luggage seat at the rear of the driver, and children's rides are vehicles that are not watched well.

従来の三輪車は一本の車体であり、旋回も小さく、無理である。A conventional tricycle is a single body, and turning is small and impossible.

Problems to be solved by the invention

（１）子供席の位置を前輪上部で横二名とする。
（２）「スイング」装置は個人差があり可変出来るものとする。
（３）「ハンドル」と連動し、前二輪が「天秤はかり」の様に左右反対に上下する。(1) The child seats will be located at the upper part of the front wheels.
(2) The “swing” device has individual differences and can be varied.
(3) In conjunction with the “handle”, the front two wheels move up and down oppositely like a “balance”.

Means to solve the problem

（１）前二輪とし、「ハンドル」（７）の前方で重心の低い横二名の子供席（６）を「前リンク」（１）上に固定する。
（２）前二輪は左右が連結され、「天秤はかり」の様に「ハンドル」（７）と連動し各々上下動が反対である事が求められる。
（３）「ハンドル」操作で旋回方向の内側の車体が低くなり、反対側は高く、傾斜し「スイング」する必要がある。
（４）「スイング」には個人差があり、必要でない方、又は大きく求められる方も無段で可変出来る事が望まれる。(1) The two front child wheels (6) having a low center of gravity in front of the "handle" (7) are fixed on the "front link" (1).
(2) The front two wheels are connected to the left and right, and like the “balance scale”, it is required to be linked to the “handle” (7) and to move in the opposite direction.
(3) When the “handle” is operated, the inner vehicle body in the turning direction is lowered, the opposite side is high, and it is necessary to incline and “swing”.
(4) “Swing” has individual differences, and it is desirable that the one that is not necessary or greatly required can be varied continuously.

（１）「前リンク」（１）の先端上部左右に二名の乗車出来る子供席（６）を横並びに「前リンク」（１）に固定し、後方上部に「ハンドル」（７）を固定する。
（２）子供席（６）下部後方左右に「ホーク支持金具」（１３）を固定し、「ホーク」（１４）には前輪（４）の車軸（５）を固定し、該「ホーク」（１４）は「ホークピン」（１５）で回動可能に支承し、前輪（４）は各々自在に上下動出来るものである。
（３）左右の「ホーク」（１４）上部には連結孔（１６）を設ける。
（４）Ｔ型連結棒（１７）の左右端には連結孔（１９）を設け該連結棒の中央軸受（２１）は「前リンク」（１）上に固定される中央軸（２０）に支持され回動可能である。
（５）左右の後連結孔（１９）の前方にはＴ型連結棒（１７）前連結孔（１６）が前後に一定の間隔で保持され、左右二本の「連結ボルト」（１８）を貫通させ、Ｔ型連結棒（１７）の下端（２４）を左右動することで、左右前輪（４）の上下動を可能とし、「スイング」が出来る。
（６）前リンク（１）と後ろリンク（２）がリンクピン」（３）で垂直に連結された場合、各「リンク」平面上を左右に折れ曲がるもので、三輪車の直進のときは両「リンク」の中心線は直線となり、旋回するときは「リンクピン」（３）で折れ曲がるものである
（７）「ハンドル」（７）の左右動で「リンクピン」（３）を中心に折れ曲がる運動となり、前リンク（１）に対し後ろリンク（２）の「リンクピン」（３）より前方に伸びる中心線と前リンク（１）の中心線は「リンクピン」（３）より前方に伸びる程、前リンク（１）との差は開き、大きくなる。
（８）後ろリンク（２）より「リンクピン」（３）より前方に伸びる事での前リンク（１）との開きの多少を「スイングローラー」（２２）と連結棒（１７）との結合による左右動を前輪（４）の左右の上下動とする「スイング」機構である。
（９）「スイングノブ」（１２）で「スイングローラー」（２２）の前後で車体全体が可変に傾斜する事が可能となる。
（１０）左右前輪（４）は三輪車の直進のときは該前輪の上下動は、中間位置で、前リンク（１）と後ろリンク（２）は直線状で、Ｔ型連結棒（１７）も選択図の１、の様に直線又は直角に位置される。
（１１）直進のとき「天秤はかり」の様に左右前輪（４）は、Ｔ型連結棒（１７）の連結孔（１６）と「フォーク」（１４）後連結孔（１９）が連結ボルト（１８）で連結され、左右前輪（４）は「天秤はかり」の様に平均を保って、子供席（６）及三輪車を保持するものであり、「ハンドル」（７）の操作で、左右前輪（４）は相反する上下動をする機構である。(1) The child seats (6) that can be used by two passengers are fixed to the front link (1) side by side and the "handle" (7) to the rear upper part. .
(2) Child seat (6) The “hawk support bracket” (13) is fixed to the lower left and right of the lower part of the child seat, and the axle (5) of the front wheel (4) is fixed to the “hawk” (14). 14) is supported by a “hawk pin” (15) so as to be rotatable, and the front wheels (4) can be freely moved up and down.
(3) A connecting hole (16) is provided above the left and right "hawks" (14).
(4) A connecting hole (19) is provided on the left and right ends of the T-shaped connecting rod (17), and the central bearing (21) of the connecting rod is attached to the central shaft (20) fixed on the "front link" (1). Supported and pivotable.
(5) In front of the left and right rear connection holes (19), a T-shaped connecting rod (17) and a front connection hole (16) are held back and forth at regular intervals, and two left and right "connection bolts" (18) are provided. By penetrating and moving the lower end (24) of the T-shaped connecting rod (17) to the left and right, the left and right front wheels (4) can be moved up and down, and "swing" can be performed.
(6) When the front link (1) and the rear link (2) are connected vertically by link pins (3), they will be bent left and right on each “link” plane. The center line of the “link” is a straight line, and when turning, the “link pin” (3) is bent. (7) The “handle” (7) is moved left and right to bend around the “link pin” (3). The center line extending forward from the “link pin” (3) of the rear link (2) relative to the front link (1) and the center line of the front link (1) extending forward from the “link pin” (3). The difference from the previous link (1) opens and increases.
(8) Connection of the "swing roller" (22) and the connecting rod (17) with the opening of the front link (1) extending forward from the "link pin" (3) from the rear link (2) This is a “swing” mechanism in which the left-right movement by the left-right movement of the front wheel (4) is the left-right movement.
(9) With the “swing knob” (12), the entire vehicle body can be variably tilted before and after the “swing roller” (22).
(10) When the left and right front wheels (4) are straight traveling of the tricycle, the vertical movement of the front wheels is at an intermediate position, the front link (1) and the rear link (2) are linear, and the T-shaped connecting rod (17) is also It is located in a straight line or at a right angle as shown in 1 in the selection diagram.
(11) When going straight, like the “balance scale”, the left and right front wheels (4) are connected to the connecting hole (16) of the T-shaped connecting rod (17) and the “fork” (14) and the rear connecting hole (19) is connected to the connecting bolt ( 18), the left and right front wheels (4) keep the average like a “balance scale” and hold the child seat (6) and the tricycle. By operating the “handle” (7), the left and right front wheels (4) is a mechanism that moves oppositely.

Claims

It is related to the “swing” device of front two-wheel and rear-wheel drive tricycles. The front wheel is held like a “balance” by operating the steering wheel, and the left and right wheels move up and down in the opposite direction. This is a “swing device” for a three-wheeled bicycle that tilts to the left and right, and the magnitude of the tilt is adjustable by individual differences.
