Claims

[Claims for Utility Model Registration] 1. A seat; a base that can be slid freely; two U-shaped tubes that are pivotally connected to each other in a crosswise manner and are installed between the seat and the base; the ends are pivoted to the base, a central portion of the one U-shaped tube is pivotally supported to one side of the seat, and a central portion of the other U-shaped tube is pivoted to the base; a tube movably engaged with the lower surface of the opposite side of said sheet; two plates each having a knurled portion formed on their lower surface and mounted parallel to the lower surface of the opposite side of said sheet; two sliding members that are provided on the movable central portion and engage with the plate; a control member that is pivotally supported on the movable central portion and has an operating portion, an engaging portion located on the opposite side thereof, and two protrusions projecting upward; , a spring member installed between the sliding member and the engaging portion of the control member, the spring member being configured to rotate the control member in a direction in which the protrusion moves upward and engages with the knurled portion; a spring member biasing the control member; when the actuating portion of the control member is manually pressed, the control member rotates in the opposite direction against the biasing force of the spring member, and the protrusion engages the knurled portion; A walker with a height adjustment mechanism that allows it to be removed from the walker. 2. The walker according to claim 1, wherein the slide members are connected at predetermined intervals by rods, and one end of the spring member is fixed thereon. 3. Each plate includes a groove, and each slide member has an overhang extending to the groove, such that the slide member slides along the movable central portion while engaging the groove. A walker according to claim 1 of the constructed utility model registration claim.
