Abstract: A movable sub-assembly (30) for accommodating and conveying at least one passenger, comprising a support (20), a cabin (22) and a guide (32) for rotationally guiding the cabin (22) relative to the support (20) about a reference axis (200) common to the support (20) and to the cabin (22), the reference axis (200) being horizontal when the movable sub-assembly (30) is in an operational state. The movable sub-assembly (30) is equipped with a stabilization system (36) comprising at least one toothed ring (38) rigidly connected to the support (20) and centered on the reference axis (200), at least one first gear (40) supported by the cabin (22) so as to mesh with the toothed ring (38), and drive means (42) capable of driving the first gear (40). The first gear (40) is supported by the cabin (22) so as to mesh with a zone of the toothed ring (38) that is located above the first gear (40).

Abstract: A mobile unit for transportation of at least one passenger comprises a car accommodating this passenger and an assembly device for fitting this car on a mobile support in rotary manner with respect to a substantially horizontal axis of rotation. The assembly device comprises a single first crown rigidly secured to the car and assembled by a bearing to a second crown performing securing to the mobile support.

Abstract: A motorized driving device drives the counterweight between balancing positions for balancing the cabin around a predetermined angular orientation of the cabin relative to the horizontal, by gravity of the whole formed by the cabin together with a possible load in this cabin.

Abstract: Manually portable structural apparatus comprising a rigid structural element configured to be releasably coupled to at least one other like rigid structural element. A bearer element having a substantially planar upper face extends between first and second elongate side beams, which each have a first connector arrangement at a first end thereof and a second connector arrangement at the second end thereof; the first and second connector arrangements providing a two-part releasable, mechanical, coupling arrangement. The first and second elongate side beams are configured to provide first and second side walls extending upwardly from the upper face of the bearer element. Use of a rigid structural element as part of a short gap crossing and as part of a stretcher. A rigid structural element in which the bearer element defines foot receiving apertures therethrough and use thereof as part of a ladder. A rigid structural element comprising carbon fibre.

Abstract: A mobile cabin for the reception and the transport of at least one passenger is to be mounted on a mobile support so as to rotate relative to a substantially horizontal axis of rotation. A motorized driving device drives the counterweight between balancing positions for balancing the cabin around a predetermined angular orientation of the cabin relative to the horizontal, by correcting the horizontal position of the center of gravity of the whole formed by the cabin together with a possible load in this cabin.
