Definitions

  • the invention relates to a belt for rowing boats.
  • the rower or the rowing team When operating a rowing boat in the previously generally known manner, the rower or the rowing team must sit with their backs in the direction of travel in order to be able to use the physical strength optimally. This initially has the considerable disadvantage that the rower or the rowing team does not see where the boat is going. It is also not possible to observe the movements of other watercraft or swimmers in front of the bow with the ease necessary to avoid collisions. With a long, relatively stable boat, it may be enough to look around in the direction of travel depending on the traffic on the water. Recently, however, the relatively short, wide and therefore barely stable inflatable boats are becoming increasingly popular. These boats are particularly popular for recreation and physical activity on the water in heavy traffic with swimmers and other boats.
  • the rower's range of motion is much more important in a short inflatable boat than in a long sports boat. If such an inflatable boat is occupied by several people, e.g. with an adult and one or more children, the rower must sit directly behind the bow, while the rest of the crew only have the stern area. The safest middle part of the boat must remain free because it is needed as a space for the hands guiding the straps.
  • the invention is therefore based on the object of designing a belt for rowing boats so that the above-described conditions can be met.
  • the invention is based on a belt according to the preamble of claim 1.
  • the object is achieved according to the invention by the features given in the characterizing part of claims 1 to 13.
  • a preferred embodiment of the invention is characterized in claims 6 to 9. Other embodiments emerge from claims 10 and 11.
  • the belt shaft is divided in the area of its storage into a blade-side shaft part 1 and a handle-side shaft part 2.
  • Both shaft parts 1 and 2 can be rotated at their mutually facing ends with a joint piece 1a or 2a about the longitudinal axis and can be fixed in any position.
  • the joint pieces 1a and 2a are in turn each pivotably mounted in a joint capsule 5 about an axis 3 or 4 leading perpendicularly through the longitudinal axis of the shaft.
  • the mutually facing ends of the joint pieces 1a, 2a are each formed in the exemplary embodiment shown in FIGS. 1 and 2 as intermeshing dental arches 6 and 7.
  • the radius of the dental arch 6 on the blade-side joint piece 1a is smaller than the radius of the dental arch 7 on the handle-side joint piece 2a. This will help with the transfer movement of the handle-side shaft part 2 on the blade-side shaft part 1 achieves a translation such that with each movement related to the direction of travel the angle spanned by the blade-side shaft part 1 is greater than the angle spanned by the handle-side shaft part 2.
  • the joint capsule 5 consists of the capsule base 5a and the capsule cover 5b. These two parts are combined by two screws 3a and 4a, which also form the bearing axes 3 and 4 for the joint pieces 1a and 2a at the same time.
  • fixing pins 8, 9 are arranged in elevations 5c, 5d of the capsule base 5a perpendicular to the capsule parting plane, which engage in corresponding bores in the capsule cover 5b.
  • the capsule cover 5b rests on the elevations 5c and 5d of the capsule base 5a.
  • the capsule base 5a has a bearing pin 10, 11 on each side, the two bearing pins lying on a common axis 12 running parallel to the capsule parting plane and transverse to the belt longitudinal axis 16.
  • the strap is placed with the two trunnions 10, 11 in a corresponding bearing on the boat's edge.
  • the movements of the belt relating to the water surface run around the axis 12.
  • the movements related to the direction of travel run around the two axes 3 and 4. This enables all the necessary movements of the belt.
  • the shaft parts 1 and 2 of the belt are each connected to the joint pieces 1a and 2a by means of a tube clamp screw connection known per se with a screw sleeve 13, 14.
  • a tube clamp screw connection known per se with a screw sleeve 13, 14.
  • Such a connection enables a rotation around when the screw sleeve 13 or 14 is loosened the longitudinal axis of the relevant shaft part 1 or 2 relative to the adjoining joint piece 1a or 2a.
  • the inclination of the belt blade to the vertical can be set and fixed in the optimal position.
  • the belt according to the invention can also be driven in a oarlock like a normal belt.
  • the joint pieces 1a and 2a are fixed at an extended angle to one another by a locking bolt 15.
  • the locking bolt 15 can be easily removed and stored, for example, in the strap handle.
  • the belt which is stiff in this way, is simply placed in a belt oar with a joint piece 1a or 2a.
  • FIG. 3 shows another embodiment of the belt according to the invention.
  • the frictional connection between the two joint pieces 21 and 22 is not produced by dental arches, but in that the one joint piece 21 has a slot guide 21a in which the other joint piece 22 is guided with a guide pin 22a.
  • the slot guide is preferably arranged on the leaf-side joint piece 21.
  • the two joint pieces 31, 32 are connected to each other by a normal pin joint.
  • the blat t-side hinge piece 31 has a slot guide 33, it slides with the on the bearing pin. 3
  • the embodiment acc. 1 and 2 on the one hand and the embodiments according to. 3 and 4 on the other hand have different advantages, but also - compared to each other - different disadvantages:
  • the embodiment according to 1 and 2 is advantageous that the belt can be folded completely on the boat edge in the longitudinal direction.
  • Another advantage is that, with the position of the movement sector of the belt blade remaining the same, the position of the movement sector of the belt handle can be changed by displacing the dental arch 7 with respect to the dental arch 6.
  • the gear ratio given by the tooth arches 6 and 7 cannot be changed.
  • the gear ratio can be changed, for example, by providing several bores in each of the two joint pieces 21 and 22 for receiving the bearing axles 3 and 4 and selecting those bores which belong to one another as required together result in the desired gear ratio.
  • the frictional connection between the two joint pieces 31 and 32 is produced by a simple pin joint, one of the two joint pieces, preferably the leaf-side joint piece 31, having a slot guide with which it is guided on the bearing axis 3.
