Description
本發明係涉及一種輪椅;特別是指一種藉由導引消隙結構而將操控桿方便輕易快速地拆離、組裝於輪椅之創新結構型態揭示者。The present invention relates to a wheelchair; in particular, to an innovative structure type revealer that conveniently and quickly detaches and assembles a joystick through a guide anti-backlash structure.
按,一般輪椅係可供身殘之使用者乘坐使用,但由於一般輪椅係為手動式輪椅,意指使用者必須自行推動輪體,或者藉由旁人的推動,才得以達到前進的目的,不僅使用上麻煩、費力,且亦對使用者來說,甚為費力。According to the general wheelchair is available for disabled users, but because the general wheelchair is a manual wheelchair, it means that the user must push the wheel body by himself or by the push of others to achieve the purpose of advancement, not only It is troublesome and laborious to use, and it is also laborious for users.
基於上述問題,後續遂有業界研發出一些可加裝於既有手動式輪椅上之輔助動力結構使其將手動式輪椅直接成為自走式之新型結構型態以為因應,係將手動式輪椅另外裝設一輔助動力結構,當殘障之使用者使用時,可藉由驅動輔助動力結構之馬達,而令輪椅前進,不僅可省去用手推輪椅之麻煩,且亦省力又方便,另外,使用者亦可利用把手控制輪體之方向,整體操作方式簡單方便。Based on the above problems, some auxiliary power structures that can be added to existing manual wheelchairs have been developed by the industry to make the manual wheelchairs a new type of self-propelled structure. In response, the manual wheelchairs are Equipped with an auxiliary power structure, when a disabled user uses it, the wheelchair can be driven forward by driving the motor of the auxiliary power structure, which not only saves the trouble of pushing the wheelchair by hand, but also saves labor and convenience. In addition, the use of The user can also use the handle to control the direction of the wheel body, and the overall operation mode is simple and convenient.
然而,綜觀目前具有輔助動力結構之輪椅,其輔助動 力結構大部分係具有一把手桿及一馬達,使其把手桿組設於該手動式輪椅前側並藉由馬達達成電力驅動,使其可轉變為自走控制式結構,並令使用者藉由控制把手桿達到控制輪椅轉向的操作。However, in a comprehensive overview of wheelchairs with auxiliary power structures, most of the auxiliary power structures have a handlebar and a motor. The handlebar set is located on the front side of the manual wheelchair and is electrically driven by the motor, which can be transformed into The self-propelled control structure allows the user to control the steering of the wheelchair by controlling the handlebar.
惟,習知手動式輪椅與把手桿其對於組接結構設計仍舊並不完善,仍有整體組構件繁多而存在組裝不便、費時之問題點;再者,為了快速且方便地將把手桿組裝在輪椅上,二者所對應的組接結構之間必須留設有一預定間隙,於組裝後,因所述預定間隙使得把手桿與輪椅之間並未緊密結合,容易造成不穩固、搖晃,進而有影響把手桿實際的操作感之虞。However, the conventional manual wheelchair and the handlebar are still incomplete for the design of the connection structure, and there are still a lot of overall assembly components, which are inconvenient and time-consuming to assembly. Furthermore, in order to quickly and easily assemble the handlebar on the On a wheelchair, a predetermined gap must be left between the corresponding assembly structures of the two. After assembly, the predetermined gap makes the handlebar and the wheelchair not tightly connected, which is likely to cause instability and shaking, and further It may affect the actual operation feeling of the handlebar.
此外,組設時,操控桿需遠離手動式輪椅一預定距離後,再將操控桿朝手動式輪椅車頭方向移動,而結合在一起,但是此組裝方式需要使用者伸長手臂才能操作,同時又要舉起具有相當重量的操作桿,據此除了造成使用者不容易且簡便地組裝之外,且直接面臨了手動式輪椅與把手桿之間無法輕易精準對位的問題。In addition, when assembling, the control lever needs to be away from the manual wheelchair a predetermined distance, and then the control lever is moved toward the front of the manual wheelchair and combined, but this assembly method requires the user to extend his arm to operate, and at the same time Lifting an operating lever with a considerable weight, in addition to making it difficult and easy for the user to assemble, also directly faces the problem that the manual wheelchair and the handlebar cannot be easily and accurately aligned.
因此仍有相當的發展改良空間存在,而這就是本創作所要進一步探討創新之處。Therefore, there is still considerable room for development and improvement, and this is what this creation wants to explore further.

Each of the anti-backlash positioning members 24 is made of a compressible material.
在本例中,各該消隙定位構件24係呈一圓型結構,供引導該卡接桿23精準對位而樞組於該限位凹部22之作用。如第7、8圖所示,在其他的實施方式中,各該消隙定位構件24的周緣其至少一部分係配合該限位凹部22而具有一凸弧段241,所述凸弧段241的兩端點242至該消隙定位構件24中心點所形成二切線243沿該凸弧段241所夾合角度係大於該凹弧段221的兩端點222至該限位凹部22中心點所形成二切線223沿該凹弧段221所夾合角度,而各該消隙定位構件24同樣地供引導該卡接桿23精準對位而樞組於該限位凹部22之作用。藉此,各該消隙定位構件24係呈一扇型結構。In this example, each of the anti-backlash positioning members 24 has a circular structure, which is used for guiding the clamping rods 23 to be accurately aligned and pivoted in the limiting recess 22. As shown in FIGS. 7 and 8, in other embodiments, at least a part of the periphery of each of the anti-backlash positioning members 24 has a convex arc segment 241 that cooperates with the limit recess 22, and the convex arc segment 241 has a convex arc segment 241. The two tangent lines 243 formed by the two end points 242 and the center point of the anti-backlash positioning member 24 are formed along the convex arc segment 241 at a greater angle than the two end points 222 of the concave arc segment 221 and the center point of the limit recess 22 The two tangent lines 223 are along the included angle of the concave arc segment 221, and each of the anti-backlash positioning members 24 is similarly provided for guiding the clamping rods 23 to be accurately aligned and pivoted to the limiting recess 22. Accordingly, each of the anti-backlash positioning members 24 has a fan-shaped structure.
此外,各該消隙定位構件24更設有一指示部(圖未示),用以供使用者判斷該卡接桿23對應樞組於該限位凹部22的方向及位置。In addition, each of the anti-backlash positioning members 24 is further provided with an indicating portion (not shown) for a user to judge the direction and position of the corresponding pivot group of the latching rod 23 on the limiting recessed portion 22.
