摘要:
A module for making a modular ferry and/or a floating bridge including a floatation tank, where the floatation tank is made in the form of two floatation half-tanks hinged together around a hinged line between an opening position in which the two half-tanks are substantially aligned and form the floatation tank, and a closing position in which a half-tank is folded back upon the other half-tank such as a lid thus forming a container box able to enclose all or part of the elements for making the ferry or floating bridge
摘要:
A suspended load-bearing structure that is formed by pneumatic structural load-bearing elements comprising an elongate hollow body, compression bars, and traction elements. The hollow body is impinged upon by gases that are lighter than air. In a first embodiment, an individual suspended structural load-bearing element is used as a ridge beam of a large tent hall whose interior has no pillars. The roof is formed by a waterproof cover, the sides of which are stretched on pillars. The cover and the structural load-bearing element are anchored to the ground by means of anchoring ropes.

A fascine is formed by an assembly of inflatable elongate members (10, 11). There may be some members that are tubes (11) and others that are pipes (10) with the tubes (11) being of smaller diameter than the pipes (10) and forming a trackway above the pipes (10) when the fascine is deployed. The members have inflatable chambers and an inflation system (20) for inflating the chamber. The inflation system (20) is located within the chamber.
摘要:
Apparatus for launching inflatable fascines comprising a conveyor system to which uninflated fascines are attachable for delivery to a launching region and an inflator to effect inflation and launch of the fascines. The conveyor (2) comprises a number of rigid conveyor members (12), each of which constitutes a fascine support location. At each of the support locations a packaged fascine (24), comprising a deflated fascine (23) housed between a backing plate (25) and a frangible or hingeable containment member (26), is attachable. The packaged fascines (24) may also contain a reservoir of pressurized gas (32) for inflation purposes. The conveyor (2) is connected via drive wheels (9) to a motor (6) such that the support locations carrying the packaged fascines (24) are sequentially delivered to a fascine launching region (14).
摘要:
An inflatable floating bridge which can be rolled up or folded up when it is not inflated. The bridge comprises two spaced-apart inflatable air hoses at the sides of the bridge, the inflation of these air hoses by means of pressurized air resulting in the laying out of the bridge. When said hoses have been inflated, and the bridge thus has been rolled out, they constitute the buoyant longitudinal side supporting means of the bridge. Between said hoses there is provided a sheet constituting the bridgeway and having its longitudinal sides fluid-tight joined to one of each hose. On the sheet there are also provided load distributing means and spacing means for the distribution of load and for the spacing-apart of the hoses.

A lifesaving apparatus for use, for example, in rescuing a person who has fallen through the ice, includes a series of slats, flexibly connected to one another, forming a long flexible mat. One end of the mat is provided with an anchoring device, used to fix the end of the mat to the shore. The other end is provided with a flotation device, which may also serve as a core on which to roll the mat. The slats serve to spread the weight of the rescuer over the ice and the entire mat serves as a path to lead the endangered person to safety.
摘要:
Vehicle with depositable ramp for forming floating bridges or ferries having short drive-on ramps at both ends, one of which is coordinated with the end over which the depositable ramp is swung and is the depositable member for the depositable ramp connected in the swing position with the depositable ramp. Furthermore the drive-on ramp that is in the form of a depositable member has a shape that is adapted to the obliqueness of the depositable ramp, and the vehicle body has a deck which extends evenly throughout its entire length, where the drive-on ramp that is not a depositable element is foldable and in the unfolded condition corresponds to the form and size of the drive-on ramp that is the supporting member.
摘要:
An inflatable device is disclosed. The inflatable device includes an airtight inflatable mat. The airtight inflatable mat has a first surface member, a second surface member and at least one side member. A plurality of support structures is substantially evenly disposed internally within the airtight inflatable mat. Each support structure is generally parallel to each other and is coupled to the first surface member and the second surface member of the airtight inflatable mat. Furthermore, a plurality of fastening mechanisms is disposed on the at least one side member of the airtight inflatable mat. The fastening mechanisms are positioned on a plane substantially centrally located between the first surface member and the second surface member, and each fastening mechanism is configured for removably connecting with another fastening mechanism disposed on a side member of another airtight inflatable mat.

A retractable dock having a ramp, with first forward and aft sides, extending from a bulkhead toward water. The first aft side joins the bulkhead via a locking mechanism. All locking mechanisms allow rotation. The dock has an aft floating assembly with an aft bridge and second aft and forward sides. The second aft side joins the first forward side of the ramp via a second locking mechanism. The aft float assembly has an aft floating unit floating on water supporting the aft bridge. The aft floating unit joins the aft bridge by another locking mechanism. The second locking mechanism joins to the ramp and either the second aft side or aft floating unit. The dock has a forward floating assembly with a forward bridge joined to the aft bridge configured for extension and retraction. The forward floating assembly has a forward floating unit floating under the forward bridge supporting it.
摘要:
An amphibious vehicle which has elements, such as caissons, floats, and ramps, arranged on a self-propelled rolling base, oriented essentially parallel to a longitudinal axis of the rolling base, when the vehicle is in a folded configuration for movement on land, and which are deployed to form a track or bridge portion oriented transversely with respect to the longitudinal axis of the rolling base, when the vehicle, alone or with another vehicle of the same design, is used to form a floating bridge or ferry. The vehicle has a deployment device for deploying elements by pivoting of four groups of the elements around four vertical shafts spaced from one another, according to at least three different configurations, each group of elements including at least one caisson.
