The present invention provides a foldable walker device, which includes: a front frame and a rear frame, wherein the front frame and the rear frame are pivotally connected to each other and can be folded and expanded relatively a seat plate arranged across the front frame and the rear frame and at least one linkage rod having a front end pivoted to the seat plate and a rear end pivoted to the rear frame. The walker device of the present invention is characterized in that the rear end of the seat plate is pulled and lifted to enable the rear end of the seat plate to tilt up, so that the linkage rod pivoted to the seat plate drives the rear frame to move forward thereby folding the walker device, reducing the space occupied by the walker device, and increasing the convenience of storing and conveying the walker device.本發明係提供一種可收折之助行裝置,包含有:一前架及一後架,該前架係與該後架相互樞接,並可相對收折及展開;一座板,跨設於該前架及該後架;至少一連桿,其前端樞設於該座板,其後端樞設於該後架。本發明之助行裝置係以拉抬該座板之後端,使該座板之後端向上翹起,令樞接於該座板之該連桿帶動該後架向前位移,而可使該助行裝置收折,縮小該助行裝置所佔據之空間,提升該助行裝置之收納及搬運之便利性。10‧‧‧可收折之助行裝置20‧‧‧前架22‧‧‧前側腳24‧‧‧上橫桿25‧‧‧下橫桿26‧‧‧前輪組27‧‧‧輪架29‧‧‧前輪30‧‧‧後架32‧‧‧後側腳36‧‧‧後輪40‧‧‧扶手架43‧‧‧立桿44‧‧‧插孔46‧‧‧背靠桿48‧‧‧握把端50‧‧‧組接件52‧‧‧通孔60‧‧‧座板61‧‧‧止滑面70‧‧‧連桿80‧‧‧折桿組82‧‧‧第一折桿84‧‧‧第二折桿86‧‧‧抵止件90‧‧‧煞車機構92‧‧‧煞車把手94‧‧‧煞車線96‧‧‧止動件
