The present invention relates to an operator platform for a construction machine and to a construction machine, particularly a road construction machine such as a road milling machine or a road paver, with an operator platform. The operator platform comprises an operator platform base, an operating panel and an operator seat, wherein an operating panel mount with a pivoting device is provided, by means of which the operating panel is pivotable about a vertical pivot axis between a first pivoting position and a second pivoting position. The operating panel mount comprises a height adjustment device which is configured such that the operating panel can be locked at different height positions independently of the pivoting positions.

In various embodiments, a drive system with a motor rotary actuator driven linkage and an override system is provided. The override system may be a manually actuated override system that, in response to a power loss or outage, is configured to disengage one or more links of drive system 100 from the electric motor rotary actuator, allowing the disengaged link to be moved and/or repositioned. Moreover, drive system 100 and, more specifically, the override system may be configured to restore normal operation to the disengaged link in response to power being restored (i.e., by reengaging the link).

A moving and locking device for a vehicle seat includes: a lower frame mounted on a bottom surface of a seat cushion; a plurality of wheels disposed underneath the lower frame in such a manner that the plurality of wheels roll on a floor panel; and a vacuum adsorption device disposed inside the lower frame and configured to be adsorbed on the floor panel by vacuum force. The vehicle seat is configured to be moved to the desired position through the rolling motion of the plurality of wheels, and configured to be locked at the desired position through vacuum adsorption of the vacuum adsorption device on the floor panel.

A multiple position convertible seat assembly for a boat includes three seat frames pivotally coupled to the boat and to each other to move from a first position as a seat, a second position as a lounge seat with leg support, and a third position forming another seat. In the third position, the seat includes a foldout cushion exposing a work surface.

A seat support structure for a working vehicle comprises a fixed plate, a parallel link mechanism, a supporting plate, a rotation shaft, a rotation plate, a seat, a rear upper shaft, and a rotation lock unit. The fixed plate is fixed on a vehicle body of the vehicle. The parallel link mechanism includes a front link and a rear link. The supporting plate is connected to the fixed plate via the parallel link mechanism. The rotation shaft is fixed on a center portion of the supporting plate. The rotation plate is rotatably supported on the rotation shaft. The seat is attached to the rotation plate. The rear upper shaft connects the rear link to the supporting plate. The rotation lock unit is provided on the rear upper shaft.

The present invention discloses a moving mechanism including a support; a driving device mounted on the support; a controller arranged on the support; two sets of moving assemblies respectively mounted at two ends of the support; wherein each of the moving assemblies includes a track and two synchronous wheels of different diameters arranged inside the track, such that the moving mechanism could be functioned and run freely over stairs, rugged road surface and all-terrain ground under the action of the driving device and the controller. The present invention also discloses electric vehicles and toys equipping the moving mechanism. The moving mechanism of the present invention overcomes shortcomings of conventional moving mechanisms by making use of a breakthrough composite structure of a half-wheel-half-track configuration in combination with an additional omni-directional wheel, whereby the moving mechanism and the electric vehicles and toys equipping the same are adaptable to different road surfaces and stairs of various angles, and also very convenient and reliable to use.
