A child enclosure including a hub member including a crank link, a substantially four bar articulated link operably connected to the crank link, a push rod connected to the substantially four bar articulated link so that linear movement of the crank link effects, through the substantially four bar articulated link, a linear driving motion of the push rod, and a slide wedge coupled to the push rod, the slide wedge includes a slider and a pivot surface biasing the slider transverse to the linear driving motion of the push rod, where the linear driving motion of the push rod extends and retracts the slider.

A vehicle steering assembly for controlling movement of a vehicle having independently rotatable left and right ground-engaging traction elements. The steering assembly comprises a steering handle coupled to the panel support structure and extending generally upwardly from the panel support structure. The steering handle comprises a laterally-extending crossmember and at least one upright extension member. The crossmember and the upright extension member are rigidly connected to one another so that shifting of the crossmember relative to the extension member is substantially prevented. The steering handle is shiftable in forward and rearward directions to thereby cause corresponding forward and rearward rotation of both of the left and right traction elements. The steering handle is rotatable in clockwise and counterclockwise directions to thereby cause a change in the relative speeds and directions of rotation of the left and right traction elements.

A driver assistance system enables brake and accelerator operation by an operation bar in a manner close to a sense of a driver of a vehicle, regardless of the degree of operation of the operation bar. Embodiments include an operation bar extending downward toward a vehicle floor panel from a manual operation area where a seated driver manually operates the operation bar, and whose lower portion is supported in a slidingly displaceable manner along an axial direction in a front-down, rear-up tilted state. The operation bar includes a brake actuation section, below the manual operation area, that actuates a brake mechanism by sliding displacement of the operation bar in a front-down direction; and an accelerator actuation section that actuates an acceleration mechanism by sliding displacement of the operation bar in a rear-up direction that is a reverse direction on the same axis from the sliding displacement in the front-down direction.

Proposed is an operation apparatus for a vehicle that improves visibility and interior aesthetics by appearing/disappearing mechanism of a button. The operation apparatus includes a panel, an operation module capable of moving, through an opening of the panel, between a first position and a second position spaced apart from each other in a front-back direction, a button placed on the operation module, a rotary link rotatably provided on an axis orthogonal to the front-back direction, a drive source for rotating the rotary link, and a cam mechanism having a guide path for inducing an angular motion of the rotary link and, thereby, moving the operation module to the first position or the second position.
