Definitions

  • the invention first relates to a rowing machine that can be placed on a sailing board (also called a surfboard), with a seat, with outrigger arms for the rowing device, with support feet, with a footrest and with a central central tube that runs in its longitudinal direction, the rowing machine with Help of the central tube is releasably attachable in the area of the sword recess.
  • a rowing machine according to the aforementioned preamble of claim 1 is known from the magazine "SURF", 1976, Issue 5, page 22.
  • an elaborate frame construction is provided, which is screwed to the central tube.
  • Such a rowing machine is heavy, which means that the overall center of gravity of a sail board provided with it is disadvantageously very high.
  • the object of the invention is to design a rowing machine according to the preamble of claim 1 and, if appropriate, associated parts in such a way that it obstructs the rower as little as possible when climbing and leaving the sailing board, or falling down, while having a light, simple construction which easy transport and assembly allowed.
  • the support feet, the footrest and the fastenings of the seat and the cantilever arms consist of cross tubes which are fastened to the central tube with retaining bushes pushed onto the central tube. Both the central tube and the cross tubes do not interfere with climbing on or leaving the sail board. If you voluntarily or involuntarily slip from the sitting position on the rowing machine into the water, there are no side frame parts in the way. In particular, the accident risks described at the beginning are avoided.
  • a rowing machine according to the invention is with rela tiv low cost. Its parts can be folded up in a very small space for transport (e.g. by car on a vacation trip). They are easy to assemble into the finished device.
  • the arrangement according to the invention allows the holding bushes to be moved continuously or in steps to the central tube and fixed in the desired position.
  • the aforementioned assembly and, if necessary, adjustment of the holding bushes can also be carried out by inexperienced laymen.
  • the rowing machine according to the invention is relatively light, since it requires far fewer parts than the previously known rowing machines. Nevertheless, the stability of the rowing machine does not suffer. Compared to the known prior art, a result that is more advantageous in practice is achieved with lower manufacturing costs.
  • FIG. 1 shows a top view of a rowing machine according to the invention with a sailing board
  • FIG. 2 shows the side view of FIG. 1
  • FIG. 3 shows a section along the line III-III in FIG. 1 on an enlarged scale
  • FIG. 4 shows a section along the line IV-IV in Figure 1, also on an enlarged scale
  • Figure 5 shows a section along the line VV in Figure 1 with a sword
  • Figures 6 to 9 in longitudinal or cross-section embodiments of the attachment of the rowing machine on the sail board.
  • a front cross tube 4 and a rear cross tube 5 are pushed onto the central tube 3 via holding bushes 4 ', 5'.
  • supports 6 are attached, preferably in the form of suction cups made of an elastic material. With this, the entire rowing machine is placed on the surface of the sailboard and held by the suction effect.
  • the central tube is attached to the sword recess (see the exemplary embodiments in FIGS. 5 to 7).
  • the rear cross tube 5, based on the direction of travel F when rowing, also serves as a footrest. A separate footrest board is therefore not necessary.
  • a block-like holding bush 9 is provided, which is provided with the cross tube or the cross tubes 10.
  • the cross tube or cross tubes 10 have openings 10 'for inserting and fastening the extension arms 8. A releasable attachment of the extension arms 8 is recommended in order to accommodate them during transport. If the extension arms 6 are omitted, and if necessary also the holding sleeve 9, the rowing machine according to the invention can also be used for paddling, the direction of travel then being reversed in accordance with number F '.
  • the cross tubes 10 with the openings 10 'can run exactly in the direction of the extension arms 8. It is an advantage of the invention that only one cantilever arm is required per side.
  • the seat 11 is held and fastened by one or two cross tubes 12 via retaining bushes 12 'also pushed onto the central tube 3.
  • the seat 11 is firmly attached to the cross tube (s), e.g. B. screwed.
  • the attachment can be detachable.
  • the cross tube 12 located in the direction of travel F in FIG. 1 can be provided with the support feet 6 as indicated by dashed lines. In this case, the front cross tube 4 is unnecessary and can be omitted.
  • all transverse tubes 4, 5, 10, 12 can be pushed onto the central tube 3 in the longitudinal direction of the central tube 3 into the desired position via their retaining bushes 4 ', 5', 9, 12 '.
  • the respective position can be locked in various ways, e.g. 1 according to FIG. 1 on the right by a plug pin 14, which in this example can be plugged through a bore in the holding bush 5 'and corresponding holes 15 in the central tube 3. This allows a gradual adjustment of the cross tube 5 and thus the footrest.
  • An analog adjustment is also possible with the other cross tubes or their holding bushes.
  • approaches 17 of the holding bush 9 there are recesses 18 for inserting one Screw, e.g. B.
  • a so-called Allen screw is provided, by means of which this retaining bush can be firmly clamped to the central tube 3.
  • An opening for accommodating an adjustment key for the Allen screw can be provided in the holding bushing 9, so that this key is always at hand.
  • the holding bushes can be injection molded from plastic. It is also possible to produce the cross tubes 4, 5, 10 and 12 entirely from plastic. But they could also consist of metal.
  • the central tube 3 and the openings of the holding bushes to be pushed over it can be round if a particularly simple shape is desired.
  • the cross sections of the central tube and the associated through openings 19 of the holding bushes can also have a non-circular profile, as shown in FIG. 3. This prevents the holding bushes and their transverse tubes from being rotated unintentionally about the longitudinal axis 3 ′ of the central tube 3. This is particularly recommended in the case of a clamping bracket of the parts mentioned on the central tube 3 according to the exemplary embodiment in FIG. 3, which enables the above-mentioned, stepless adjustability of these parts in the longitudinal direction.
  • cross-sectional profile of the central tube 3 shown in FIG. 3 is relatively easy to produce in terms of rolling technology without too much deformation work, since this shape is relatively little of the circular shape of a round one. Rohr deviates.
  • Fig. 4 shows that the oarlocks 7 can be rotatably attached to a plastic block 20, wherein the block 20 can be firmly pressed into the tube forming the extension arm 8 with an extension or pin 21.
  • a sail board equipped with a rowing machine according to the invention can be driven with or without a sword.
  • 5 shows an embodiment of a sword 22 which can be inserted from below with centering shoulders 23 into the sword recess 2, and which can be placed against the underside of the board with retaining strips 24.
  • the sword is held in this position by the means used to attach the central tube 3 to or in the sword recess 2.
  • This can be done according to the present embodiment in such a way that 3 holes 25 are provided in the central tube, through which an elastic band or rope 26 made of rubber, plastic or the like can be passed.
  • the tape is at one end through openings that z. B. have a so-called keyhole shape, passed in projections 27 of the centering projection 23 and held behind it by means of a knot or the like 28.
  • a bracket 29, z. B. a quick release.
  • an elastic rope 26 ' can also be pulled through the holes 25 and held on the top side by a quick-release fastener 29, it being on the underside of the board by a rubber or plastic tube 30 running in the longitudinal direction and covering the sword recess 2 from below passes that can not damage due to its elasticity G as board.
  • a cover 31 running in the longitudinal direction of the sword recess 2 and shown in cross section is provided, which fits into the sword recess with a projecting part 32, possibly carries a sword and is penetrated by a clamping screw 33 which has a hook-like end 34 overlaps the central tube 3.
  • the clamping screw could also penetrate the central tube 3 (not shown).
  • a screw thread with a screw nut 36 is provided at the other end 35 of the clamping screw.
  • the screw thread of the end 35 can be so long that this screw fastening can also be used on boards 1 of different thickness.
  • a tension screw connection would also be possible, which runs in the longitudinal direction of the sword recess and is effective (not shown).
  • the sword 37 can also be fastened in the recess in a different manner and held together with the central tube 3.
  • angles with horizontal legs 36 and legs 39 leading approximately vertically upwards according to number 41 are riveted on both sides.
  • the legs 38 serve to abut the underside of the board 1, while the legs 39 are bulged out to the side and thus form a centering within the sword recess 2.
