200948651 九、發明說明： 【發明所屬之技術領域】 本發明係有關一種具有轉向直控式定止裝置之轉 輪，尤指一種操作者可利用單一方向踩踏的動作完成啟 動或解除的動作，在踩踏時，使其壓鈕連動推桿，藉推 桿推轉卡桿，使卡桿相對外殼形成二個伸縮定止的位 置，而可控制轉輪停車啟動及停車解除，藉以達到使用 ©方便及提升安全性之目的者。 【先前技術】 按習知手推車停車裝置的方法種類繁多，譬如有一 分別裝置於後輪兩侧的停車裝置，在此裝置上設有踩踏 板，並在踩踏板下方設有嵌齒，使踩下踏板時讓嵌齒嵌 入後輪上所叹置之齒部空缺，藉此停住後輪。但由於停 車的方式的操作係分左右兩側各別控制，故操作不便。 遇緊急狀況慌亂時，操作者常常無法立即反應將兩侧的 ©輪胎停住’而造成手推車晃動及旋轉。單邊各別停車裝 置的設計並非完全不適用於嬰兒手推車，目前仍有嬰兒 手推車使用此設計裝置，礙於環境的限制，此裝置多用 於緩慢行駛的嬰兒手推車或行駛於較為平穩路面的嬰兒 手推車等，仁對於行使速對較高或行驶於較陡山肖的斜坡 時’基於安全因素的考量，兩後輪同步停車及快速操作 就更為重要’目前亦有國家將單踩兩側同步停車的功能 列為產品設計之安全標準者，如英國。 200948651 已知或已揭露嬰兒手推車停車裝置，有些能滿足前 述功能者，如德國專利DE29818659U1，揭露了一種可以 同時煞住或是釋放兩個輪子的嬰兒車煞車裝置，此以煞 車裝置利用踩踏或是向上勾起一種可作直線往復運動的 凸板元件連動一管狀的煞車套管延著輪轴的軸向移動， 藉由煞車套管套住輪軸之花瓣形煞車鰭片的設計，提供 煞車或是釋放的功能，使用者必須透過下凸版的方式煞 車’欲解除煞車時則必須利用足尖將凸板向上挑起；而 ❹美國第5, 460,399號專利也揭露了一種具有相同功能的 煞車裝置，此一煞車裝置利用一種可以上下擺動的踏板 連動二根煞車桿’其中的踏板底部設置有一對彼此之間 保持有一夾角的斜面煞車時使用者必須藉由踩下踏板的 方式透過斜面將煞車桿同時推入輪浮之中，欲釋放煞車 時則同樣需要以足尖將踏板向上挑起；中華民國第 501506號專利揭露當使用者踩下踏板面啟動一煞車裝置 ❹進入一煞車作動狀態時，亦會帶動將連桿位置升起，連 桿會同時帶動另一組煞車裝置進入煞車作動狀態，以兩 組煞車裝置來箝制嬰兒車之輪子V更可以加強嬰兒車之 煞車效果;前揭三種已知技術具有相同的操作方式使 用者都是藉由踩下或是以足尖挑起踏板的方式完成煞車 或是解除煞車的操作，操作的方式雖然簡單，但是以足 尖挑起踏板的操作方式卻容易損害使用者的鞋面。 另外嬰兒手推車停車裝置裡的油壓力導弓丨裝置， 200948651 部分都是利用鋼索導引啟動和解除停車裝置，已知或已 揭露嬰兒手推車停車裝置，例如··美國第5, 713, 585號專 利案提出，此專利揭露了一種嬰兒車的安全煞車裝置， 此安全煞車裝置可以在使用者離開嬰兒車的位置時，限 制住輪子無法轉動，使用者若欲推嬰兒車時必須釋放停 車裝置方可使嬰兒車移動；此煞車裝置更包括有一個以 可移動之關係配置在嬰兒車扶手之停車握把，使用者必 ❹須握住此煞車握把像上施力才能使停車裝置脫離；前揭 已知技術的操作方式，使用者都是藉由鋼索導引停車裝 置方式完成煞車或是解除煞車的操作，操作的方式雖然 簡單’但是若使用者行走在陡坡時，則使握把的角度不 易於使用者啟動或解除煞車裝置，而導引裝置是使用鋼 索，則容易造成鋼索鬆脫，使啟動和解除停車裝置反應 遲緩，造成危險？ . 【發明内容】 © 本發明之主要目的，在於提供一種可解決習知手推 車的手動停車問題推車油壓停車系統。本發明之主要目 的，在於提供一種可解決習去0手推|的手動停車問題的 具有轉向直控式定止裝置之轉輪。其技術手段係包括具 有轉向直控式定止裝置之轉輪，其包括有一座體、一停 車開關組件及二受卡面1體固定於—具有橫伸輪抽的 輪架上，該輪軸供設置轉輪。該停車開關組件裝置在該 座艘上，其包括有一外殼、二推桿、二卡桿一壓紐、 200948651 -彈署及二第二彈簧。該外殼具有一左端、一右端， 該左端及該右端且與該輪轴之轴線平行的通 固第=内壁環佈有等間距的複數個第-凸條及複數 固第-凸條，母兩相鄰的該第一凸條及該第二凸條之間 2形成-沿著該通孔縱向延伸的導槽，該導槽一端為 端為開口’每—第—凸條及第二凸條的末端分 ’形成鋸齒狀而具有同向傾斜的一第一斜導面及一第二 ❹斜導面，該第-斜導面與該第：斜導面的—端以一陡隋 卡制面相接，並使該第—斜導面與該卡制面圍成一凹陷 的卡制部。二推桿可移動地以穿置在該外殼之該通孔 内’其周面分別設有凸緣，該凸緣供嵌人對應的該一導 槽’而可沿著該導槽來相對於該外殼做橫向移動使推 桿相對該外殼只可橫向移動而不可轉動，推桿一内端分 別位於該通孔之中段’一外端設有複數個沿著其軸線環 佈連續第-凹陷，每-該第一凹陷包括有具相反斜率且 ❹相朝向的一斜推面及一止擋面。該壓鈕可上下移動地自 該中段之S亥開槽穿入該通孔内，其頂端浮露在該外殼的 頂部，且其兩侧分別設有與該第一推桿及該第二推桿對 應的連動手段，藉由該壓鈕下移，經由該連動手段而使 。亥第一推柃及該第二推桿分別向該外殼的該左端及該右 端移動。每一該第一彈簧分別提供對應的該第一推桿及 該第二推桿朝向該通孔之該中段移動的彈力。卡桿可移 動及轉動地穿置於該通孔内，該卡桿外周面中段分別環 200948651 认有凸環，該凸環一端面環佈有複數個與該第一凹陷 相對應的第—凹陷’每—該第二凹陷包括有具相反斜率 且相朝向的一受推面及一受擋面，每一該受推面與一該 斜推面對應’每一該受擋面與一該止擋面對應，該凸環 的周面刀別％佈有複數個與該導槽或該卡制部對應的突 起卡鍵。每一該第二彈簧分別置設於該外殼與該第一卡 桿及該第一卡桿之間，分別提供對應的卡桿及推桿移動 ❹的彈力。受卡面與輪架上的輪軸同步旋轉，該受卡面上 认有至；一党抵部。藉由該壓鈕相對該外殼下移而以 該壓紐的該連動手段將該第一推桿及該第二推桿分別向 該外殼之該左端及該右端移動，以其斜推面與該卡鍵的 該受推面接觸’而可使該第一卡桿及該第二卡桿分別朝 向該外殼之該左端及該右端移動並做旋轉，而使該第一 卡杯及該第二卡桿之該卡鍵分別移至該第一導槽及該第 二導槽内而位於一第一位置，或使該卡鍵分別移至對應 ❹的該卡制部内而位於一第二位置，該第一位置為該第一 卡桿及該第二卡桿末端卡抵於對應一該受卡面之該受抵 部的位置，該第二位置為該第一卡桿及該第二卡桿末端 脫離卡抵該受抵部的位置。 . . _ _ . . . .. .... ... 【實施方式】 壹·本發明的基本結構特徵 請參看第1至6圖所示，本發明所實施之具有轉向 直控式定止裝置之轉輪，其包括有： 200948651 一座體（10)，其固定於一具有橫伸輪軸（11)的輪架 (12)上，該輪轴（11)供設置轉輪（13);

Description of the Invention: [Technical Field] The present invention relates to a reel having a steering direct control type fixing device, and more particularly to an action that an operator can perform a start or release operation by stepping in a single direction. When stepping on the pedal, the push button is linked to the push rod, and the push rod is used to push the rod to make the rod form two telescopically fixed positions relative to the outer casing, and the runner can be controlled to start and stop the parking, thereby facilitating the use of For the purpose of improving safety. [Prior Art] There are various methods for the conventional trolley parking device, such as a parking device that is respectively disposed on both sides of the rear wheel, and a pedal is provided on the device, and a cog is provided under the pedal to make the pedal When the pedal is inserted, the cogs are embedded in the teeth of the rear wheel and the teeth are vacant, thereby stopping the rear wheel. However, since the operation of the parking mode is controlled by the left and right sides, the operation is inconvenient. In the event of an emergency panic, the operator often fails to react immediately by stopping the tires on both sides, causing the cart to shake and rotate. The design of the unilateral parking devices is not completely unsuitable for baby strollers. There are still baby strollers using this design device. Due to environmental constraints, this device is often used for slow moving baby strollers or baby strollers on smoother roads. Etc., when it comes to speeding up the slopes or driving on the slopes of the steeper slopes, 'based on safety factors, the two rear wheels are synchronized and the quick operation is more important. 'There are also countries that will step on both sides of the same parking. The functions are listed as safety standards for product design, such as the UK. 200948651 Known or disclosed baby stroller parking devices, some of which can meet the aforementioned functions, such as the German patent DE29818659U1, discloses a stroller brake device that can simultaneously hold or release two wheels, which is used by the brake device or Upwardly arranging a recoil element that can be linearly reciprocated to interlock a tubular brake casing to move axially along the axle, and to provide a brake by means of a bushing sleeve covering the petal-shaped brake fin of the axle The function of the release, the user must drive the car through the lower version of the way. When the vehicle is to be unloaded, the toe must be used to pick up the convex plate. The US Patent No. 5,460,399 also discloses a brake device having the same function. The brake device uses a pedal that can swing up and down to link two brake levers. The bottom of the pedal is provided with a pair of inclined surfaces that are kept at an angle with each other. The user must simultaneously push the pedal through the inclined surface. Push into the float, when you want to release the brakes, you also need to lift the pedal up with the toe; The Patent No. 501506 discloses that when the user steps on the pedal surface to activate a brake device and enters a brake state, the position of the link will also be raised, and the link will simultaneously drive another set of brake devices into the brake state. By clamping the wheel V of the stroller with two sets of brake devices, the effect of the stroller can be enhanced. The three known techniques have the same operation mode. The user uses the method of stepping on or pushing the pedal by the toe. The operation of the brakes or the release of the brakes is simple, but the operation of picking up the pedals with the toes is likely to damage the upper of the user. In addition, the oil pressure guide bowing device in the baby stroller parking device, 200948651 part is the use of the cable to guide the start and release of the parking device, known or has revealed the baby stroller parking device, for example, US Patent No. 5, 713, 585 It is proposed that the patent discloses a safety brake device for a baby carriage. The safety brake device can restrict the rotation of the wheel when the user leaves the baby carriage, and the user must release the parking device if the user wants to push the baby carriage. The baby carriage is moved; the brake device further includes a parking grip disposed on the armrest of the baby carriage in a movable relationship, and the user does not need to hold the brake grip to apply force to disengage the parking device; According to the known operation mode, the user completes the operation of braking or unloading the vehicle by means of the cable guiding parking device. The operation mode is simple, but if the user walks on a steep slope, the angle of the grip is not easy. When the user activates or releases the brake device, and the guide device uses a steel cable, it is easy to cause the cable to loosen. And release the parking system slow to respond, dangerous? SUMMARY OF THE INVENTION The main object of the present invention is to provide a cart hydraulic parking system that can solve the manual parking problem of a conventional hand truck. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a reel having a steering direct control type stop device that can solve the manual parking problem of the conventional push. The technical means comprises a runner having a steering direct control type fixing device, comprising a body, a parking switch assembly and two receiving surface 1 fixed on a wheel frame having a transversely extending wheel, the axle is provided Set the wheel.
