摘要： A knob-less horizontal-shift fire door lock includes a base including a longitudinal bar, an unlocked-state positioning member arranged in the longitudinal bar and having a positioning section; a latch pivoted to the base and having a free end elastically biased outside the base to engage a keeper on a door jamb; a push board pivoted in the base; and a handle bar slidably mounted on the longitudinal bar. The handle bar is biased by an elastic element to protrude outwards and moving a guide pin to slide in a guide groove of the positioning section. The handle bar is depressible toward the longitudinal bar to move the push board to drive the latch to retract into the base to achieve an unlocked state. The handle bar is further shiftable horizontally to cause the guide pin to slide into a horizontal groove of the positioning section for being secured in position.

摘要： A light-duty vehicle with an adjustable wheelbase includes a linkage assembly composed of at least one main rod, a movable support, at least one movable rod and at least one adjusting rod, at least one power source connected in the linkage assembly, a seat mounted on a connecting rod having one end pivotally connected to the movable rod, and a driving wheel set composed of at least one front wheel and at least one rear wheel. The rear wheel is rotatably connected to the adjusting rod, while an opposite end of the main rod is connected to a fixed rod, which is coupled to a front fork above the front wheel. Thereby, when the power source modifies the linkage assembly in posture, the wheelbase between the front wheel and the rear wheel is changed so that the seat is adjusted in posture and altitude.
