    • An invalid walker includes a means for locking at least one of the side frames in a hyperextended position. The walker includes a pair of U-shaped side frames whose front legs are connected by a cross brace member. Each of the rear legs of the side frames is connected to the cross brace member by a telescoping tubular device in which a first tube telescopes into and is received by a second tube. A pushbutton mechanism is housed inside the first tube and positioned within a first aperture in the first tube. The second tube includes a pair of locking apertures, one for locking the side frame in a first normal open position and the second for locking the side frame in a hyperextended position. The apparatus further includes a foot adjustment means for levelling the rubber foot of the hyperextended rear leg of the hyperextended side frame with the feet of the other three legs of the apparatus.
    • 无效的步行器包括用于将至少一个侧框锁定在过度延伸位置的装置。 助行器包括一对U形侧框架,其前腿通过横向支撑构件连接。 侧框架的每个后腿通过伸缩管状装置连接到横向支撑构件,其中第一管子伸入并被第二管接收。 按钮机构容纳在第一管内并且位于第一管中的第一孔内。 第二管包括一对锁定孔,一个锁定孔用于将侧框架锁定在第一正常打开位置,第二锁定孔用于将侧框架锁定在过伸位置。 该装置还包括脚部调节装置,用于使超伸出侧框架的超伸展后腿的橡胶脚与设备的另外三个腿的脚平齐。
