Definitions

  • the invention relates to a articulated vehicle according to the preamble of claim 1.
  • the articulated vehicle is primarily designed as a floatable articulated vehicle, that is to say as a articulated boat.
  • a articulated vehicle is known from GB-A 1 096 359.
  • the hull In known boats, the hull is designed as an essentially rigid body, which follows the movements caused by the movements of the water as a whole, without deforming significantly. In cases where the carrying water has a very uneven surface and / or has a steep gradient and / or has a very limited extent perpendicular to the direction of travel, a boat with a rigid hull proves to be very bulky and less maneuverable, and the hull is partially exposed to high mechanical loads, for example because large parts of the boat sometimes protrude from the water.
  • An example in which such water conditions exist is white water rivers or streams, as well as corresponding artificial white water rides in amusement parks.
  • a floatable articulated vehicle which consists of individual members which can be bent against one another via swivel joints with horizontal axes.
  • the individual links consist of floating boxes with a bottom that can accommodate a payload.
  • Each articulated link consists of two differently constructed, interlocking mechanical engineering structures, each of which is arranged at one end of a vehicle link. In each case adjacent vehicle links are coupled together to form an articulated link by means of pins, so that the links, apart from their mutual rotatability about the horizontal axis of the articulated link, together form a rigidly connected unit.
  • the known articulated vehicle is a large ship for the transport of goods.
  • a device that is primarily intended for driving on snow and is intended to learn how to ski.
  • the device consists of an egg-shaped inflatable body which is connected to a bar shaped essentially like a ski.
  • the egg-shaped body is firmly connected to the ski bar.
  • the inflatable body is shaped so that a person can sit on it in the riding position and consists of several elements with different inflation pressures, so that folding zones form the joint-like areas.
  • the device does not have its own stability.
  • the device can also be used for driving on water, whereby it is used like a water ski.
  • an inflatable boat which consists of a plurality of frame-shaped tubular members abutting one another, all of which are inserted into a common outer skin made of a suitable fabric.
  • adjacent hose members are connected to one another by banding the adjacent hose member sections of both hose members. Despite this connection, there is a certain, relatively low mutual mobility between the adjacent hose members.
  • the invention has for its object to develop a articulated vehicle of the type mentioned, which is particularly suitable for navigating artificial whitewater rivers, which allows bending in the direction of travel of adjacent members in any degree of freedom and which is simple in its construction.
  • Figures 1 and 2 show the basic structure of a link vehicle according to the invention, in which the entire hull consists of a circumferential frame open in the vertical direction.
  • the frame parts attributable to the individual links 1 to 4 are designed as floating bodies, the cross section of which can have any shape, for example circular or rectangular.
  • the bow member 1 and the rear member 1 each consist of a single frame part 11 and 11 d bent by 180 °. Instead of this single frame part, these links 1 and 4 can of course be made up of different rigidly connected frame parts. It is also not necessary for all frame parts to be designed as floating bodies.
  • articulated links 13 The lateral frame parts of adjacent links are connected to one another via articulated links 13. These articulated links are arranged as elastically deformable intermediate pieces between the relatively rigid frame parts 11.
  • the frame parts belonging to a link can be connected to one another by transverse connectors 18, 19, 20 running perpendicular to the longitudinal direction of the boat.
  • These cross connectors can consist of a simple rod, such as the cross connectors designated 18, or they can also be designed as floating bodies, such as the cross connectors labeled 19.
  • the cross connectors clearly define the width of the boat.
  • the cross connectors are preferably at the ends in the longitudinal direction of the links, so that the individual links form a subframe with the largest possible opening area 23.
  • a common cross connector can also be used, which extends from one articulated link to the opposite one.
  • This cross connector common to two links can also be designed as a floating body, as is shown on the cross connector 20 in FIG.
  • the partial frames of the individual links thus represent essentially rigid bodies in FIGS. 1 and 2, which can be bent as desired in relation to one another.
  • Rigid, downwardly closed baskets from which the payload of the boat is received, can preferably be inserted into the passage surfaces 23 of these subframes. These can be baskets for people.
  • the baskets are then preferably provided with benches, as is explained in more detail in the exemplary embodiment according to FIGS. 3 to 5.
  • the depth of these baskets can be such that they are immersed in the water and contribute to the overall buoyancy of the boat.
  • the baskets are supported on the frame parts 11 and / or the cross connectors. If there are no cross connectors between the frame parts 11a to 11f, the baskets used can also be attached to the frame parts in such a way that the width of the boat is precisely determined by the baskets.
  • the articulated members 13 for example, foams with closed pores come into consideration, which are accommodated in flexible, waterproof casings.
  • the articulated members can also consist of inflatable chambers, the pressure of the gas enclosed in these chambers, normally air, being so dimensioned that these chambers are considerably softer and easier to deform than the essentially rigid frame parts. These chambers then form so-called air hinges.
  • the boat hull shown in Fig. 4 in plan view consists of three links 1, 2, 3.
  • the frame parts 31 a to 31 d are designed as inflatable tubes, the two end frame parts 31 a and 31 c bent by 180 ° expediently into individual sections by bulkhead walls 32 are divided.
  • the articulated members 33a to 33d are also designed as inflatable chambers, and the same applies to the cross connectors 34 and 35.
  • the inflatable chambers forming the articulated members are provided with connecting pieces 36a to 36d provided for the cross connector.
  • the entire space delimited by the bulkhead walls 32a, 32b, 32c represents a single chamber.
  • Baskets 41-43 can be inserted into the partial frame opening formed by each link, which are shown in FIG. 3 and can be seen particularly well in the cross section according to FIG. 5.
  • the baskets lie on four sides on the longitudinal and transverse hoses and can be attached to the spar trimmings using rope ropes.
  • the bottom 53 of the baskets lies somewhat higher than the lower limit 54 of the hoses in order to avoid the baskets from touching the ground.
  • they also dive into water 55 and thus contribute to the buoyancy of the boat.
  • a grating 45 is arranged slightly above the bottom of the baskets, under which splash and rain water collects. Benches 44 are installed or can be used in the baskets.
  • Protective and rubbing strips 46 are arranged on the outer sides and on the underside of the longitudinal hoses.
  • the baskets are provided with a bulwark 47, which is pulled up at the two end baskets towards the ends to protect against splashing water and which expediently do not protrude horizontally over the hose in order to avoid hitting the bank walls when the boat is used in white water channels .
  • the air chambers 33a to 33d which form the articulated members (air joints), are only inflated with a relatively low pressure, they are very soft and easily deformable.
  • the other hose parts act as practically rigid bodies, so that the limbs of the boat can bend against one another via the joint chambers around axes which run essentially transversely through the joint chambers.
  • the joint chambers can easily bend against each other about vertical axes. To a certain extent, they can also be displaced parallel to one another perpendicular to the longitudinal axis of the boat.
  • the walls of the boat belonging to the articulated chambers are preferably produced from more flexible and crushable material than the other frame parts and cross connectors, which are also constructed as hose parts.
  • the boat shown in Figures 3 and 4 has a length of about 5 to 6 m and is designed for 6 people. It is understood that by adding additional links, the boat can be built significantly longer and for significantly more people.
  • the surfaces 51 of the baskets which are immersed in the water and which run in the longitudinal direction of the boat ensure that the boat is pressed into the place of the water flow (usually the middle of the channel) in which the greatest flow speed prevails.
  • the surfaces 52 of the baskets which are immersed in the water and run perpendicular to the longitudinal direction of the boat ensure that the longitudinal axis of the boat is in the direction of flow. This prevents the boat from crossing. This promotes a fast operation on commercial wild water rides.
  • the boat consists of two long, flexible (elastically deformable) floating bodies 61 arranged essentially in parallel, which are preferably designed as air hoses. These hoses are embedded in corresponding receiving openings of a rigid front part 62 and a rigid rear part 63 and are firmly connected to these parts.
  • rigid baskets can be inserted one after the other, which are placed on the floating bodies 61 and releasably attached to them. The attachment can take place, for example, with expanders 65, which comprise the floating body 61.
  • the individual members of the boat are formed by the baskets with the associated parts of the float 61.
  • the bow part 62 and the rear part 63 each represent a link. Thanks to the flexibility of the floating bodies, the links can bend towards each other and / or shift parallel to one another. The degree of bendability and mutual displaceability can be adjusted on the one hand by the degree of flexibility of the floating bodies and the distance between two adjacent baskets or basket and bow or rear part 62, 63. Benches 67 are again arranged in the baskets, as indicated in one of the baskets in FIG. 6 and can be seen better in the enlarged cross-sectional view according to FIG. 8. The basket shown in Fig. 8 is formed on the sides so that it encompasses the floating bodies 61 from three sides with a tolerance that is appropriate for mounting. An elastic rope 65 (expander) is then stretched over the downwardly open side.
  • the baskets 64 as well as the front part 62 and the rear part 63 are provided with protection and rubbing strips 66 both laterally and downwards.
  • the boat of FIGS. 6 to 8 is special. suitable for so-called shooting rides in artificial waterways. It is guided in a channel in which the boat is supported with the protective and rubbing strips shown.
  • Floatable articulated vehicles that is articulated boats, have been described above. It often happens with artificial wild water serbahnen, especially in the case of weft tracks, that the leading channel does not always carry enough water to keep the vehicle floating. Finally, closed rail systems are also conceivable that carry no water at all or only a small amount of water, which is used practically only for lubrication.
  • all or part of the articulations of the vehicle are provided on their underside with sliding surfaces with which the vehicle can be placed on a solid base, in which it is usually the bottom of a fairway or train leading the vehicle.
  • the areas of the links with which the link is supported when it is placed on the track are referred to as “bottom of the links”.
  • these areas also include obliquely extending areas of the links. Since the rigid sliding surfaces are individually provided for each link, the links can be bent and moved relative to one another.
  • the sliding surfaces can be designed in such a way that the underside of the baskets projecting downward is covered over a large area with lubricious material. Another possibility is to attach runners to these baskets or the frame parts, which in turn are covered with slidable material or consist massively of such material.
  • sliding surfaces can also be provided on the outer sides of the links, with which the vehicle is supported against a side wall of the leading channel when striking or resting.
  • the frame parts and / or the cross connectors can also be designed as floating bodies, so that the vehicle is also buoyant.
  • This amphibious embodiment has the advantage that the vehicle can be caught in a pool of water at the lower end of the track.
  • the frame parts and / or cross connectors from non-buoyant material, for. B. from simple spars or profile beams. Also, if immersion in water is not provided, the baskets need not be closed at the bottom.
  • the material of the sliding surfaces must be such that it has the lowest possible coefficient of friction on the material of the leading track.
  • special plastics come into consideration, e.g. B. Hostalen under the trade name «GUR».
  • the leading path forming the base can, for. B. made of steel or plastic.
  • FIGS. 9 to 11 show, in the same representation as FIGS. 3 to 5, a floatable articulated vehicle which differs from that of FIGS. 3 to 5 in that it is also on a solid base can be put on and is able to slide well on it.
  • the individual links 1-3 of the vehicle are provided with sliding surfaces, specifically with runners 73, 74 which run in the longitudinal direction of the links and which are attached to the flat underside of the baskets 41 to 43.
  • the surfaces of the runners touching the bottom of the channel 80 are covered with a highly slidable material 75, which is chosen so that the coefficient of friction with the material of the channel 80 is very small.
  • runners 76 with a slidable covering 75 are also attached to the frame parts, as is indicated in FIG. 11 for the frame part 31 b. Since the articulated vehicle can also strike the side walls 80a, 80b of the gutter when it is traveling through the gutter, in particular in curves, the limbs can also be provided with sliding surfaces on the sides. This sliding surface can be attached directly to the frame part, as is shown for the frame part 31 b in FIG. 11, where a runner 77 with slidable material 75 is arranged laterally on the frame part. These runners 77 with sliding surfaces are also shown for all six frame parts in FIG. 10.
  • FIGS. 12 to 14 show a similar articulated vehicle to that of FIGS. 6 to 8, the same reference numerals being used again for corresponding parts.
  • the way in which FIGS. 12 to 14 are represented also corresponds to that in FIGS. 6 to 8.
  • the bottom surfaces of the baskets 41 to 43a are covered with a highly slidable material 75.
  • front and rear frame parts 62, 61 front part and rear part.
  • the parts of the baskets or the individual links which protrude the most to the side can be covered with highly slidable material 75, as can be seen in FIGS. 13 and 14.
  • the two non-rigid frame parts 61 can also consist, for example, of non-floatable solid rubber rods instead of as floating bodies.
  • runners can be provided on the baskets, which in turn are coated with sliding material, as shown in FIGS. 9 to 11.
  • directly lubricious material can be applied to the surfaces of the baskets instead of the runners.
  • the basket must be extended so far down that its lower interface is lower than that of the frame parts.
  • the runners or the immediately applied lubricious material can extend over the full length of the limbs in the direction of travel or over part of this length. It must always be ensured that optimal relationships are created between the overall friction on the one hand and the contact pressure on the leading channel on the other.
  • the slidable surfaces touching the bottom or the side walls of the channel are drawn obliquely upwards on their front edge in the direction of travel, as is indicated, for example, by a in FIG. 9 or by b in FIG. 12.
  • FIG 15 shows in the same representation as Figure 14, an embodiment according to the invention with a different design of the sliding surfaces.
  • the sliding surface 101 here consists of a band running perpendicular to the longitudinal direction of the vehicle, which extends over the entire outer circumference (with the exception of the opening upwards) of the link.
  • the band is guided on an arch which is adapted to the arch 103 of the leading channel 80.
  • the band can either be designed as a self-supporting body or it must be provided with a support structure in the region of the transition zone 102.
  • the tape is made of highly slidable material or is covered with such material 75 on the outside.
  • the band can also be designed such that it only extends over the transition zones 102. In the longitudinal direction of the link, the band can extend over the entire length of the link or consist of several bands arranged at a distance from one another.
  • the lubricious material can be applied to the surfaces supporting it in any way.
  • screws, gluing or welding are possible.
  • the slidable surfaces can be provided with scales or grooves which, on the one hand, can have the purpose of preventing the vehicles from sliding backwards and / or, on the other hand, can be such that, in the presence of a water film in the leading groove, this water is more easily between the sliding surface and the groove bottom can build up a sliding film.
