The invention discloses a stereoscopic garage. The stereoscopic garage is characterized in that four windlasses of a winch are driven to rotate by using a winch motor, and simultaneously four steel wire ropes are simultaneously wound and released, so that a lift car cannot rotate at random; a carriage is connected with a top seat of the lift car through a horizontal rotating device of the carriage, which is arranged below the top seat of the lift car; therefore, when the carriage rotates, a car carrying device arranged on a carriage base rotates together with the carriage, and the phenomenon that the car carrying device bumps a carriage pillar is avoided; when a trolley or a large vehicle for lifting or transversely moving the stereoscopic garage is started or stopped, the lift car swings due to the inertia of the lift car; and an axial flow fan of an inertia damping device of the lift car can be used for reducing the swing amplitude of the lift car. The car carrying device in the stereoscopic garage is formed by using a horizontal moving motor for driving walking wheel gears to rotate on walking racks, thus a mounting bracket and a supporting plate are driven to move horizontally; and a hydraulic jack on the mounting bracket is used for putting a car on the supporting plate on garage steps. As the center of gravity of the carriage is biased after the car is put on the supporting plate, the biased center of gravity can be adjusted by a center-of-gravity adjusting device.

The second transverse groove, provided in an area between the Chopart's joint and the Lisfranc joint, including the navicular bone where the arch of the foot is highest, is deeper than the first transverse groove, and is equal to or deeper than the third transverse groove. Therefore, the rest of the midsole is thin and it becomes easier for the shoe sole to flex, thereby facilitating the upward displacement of the area where the arch is highest. Thus, it is possible to suppress the lowering of the arch even if an exercise is continued over a long time. On the other hand, a flexion area including at least one third transverse groove is provided directly below the talus, and has a larger width than other transverse grooves. This makes it easier for the rear foot portion directly below the talus to flex, thereby facilitating the upward displacement of the area of the arch.

Planter systems allow for the raising, lowering, holding, locking and releasing of a planter on a vertical support structure. The planter assembly may include a carriage, to which one or more planters is attached.

A tether guided over a pulley may be retracted or extended by winding it around or unwinding it from a winch, cleat or windlass to causes the planter assembly to rise or descend. When raised to a locking height, the planter assembly causes a mechanical locking mechanism associated with the planter assembly to move into a locking position, securing the planter assembly to the vertical support. Further raising releases the locking mechanism. Attachable items such as banners, flags, hangers and the like may be coupled to the carriage. Optional irrigation supplies water to the planter assembly and/or surrounding terrain. The planter may be unitary or a plurality of assembled planter components or sections. Drain and cleanout ports facilitate draining and cleaning of the planter assembly. An optional waterfall embodiment includes a reservoir section with overflow ports to drain water into a lower reservoir at the base of the vertical support, from which a pump supplies the water back to the reservoir section of the planter assembly. A plurality of conduits for electrical, data and plumbing extend through the vertical support.
