Definitions

  • the invention relates to a mast foot bracket for a sailing surfer.
  • a slide rail is embedded in the deck of the surfboard, which runs in the longitudinal axis of the surfboard.
  • a slide block is slidably guided in this slide rail, in which the mast base is held.
  • the mast On space sheet courses, the mast is now moved backwards with the gliding block, since the windsurfer travels on a less gliding surface on this course and is much easier to control by shifting the pressure point to the center of the board; in In this case, the maneuverability of the surfboard improves because the effect is achieved as if you were riding a shorter board.
  • the sword is fully folded in here.
  • a locking device is attached to the slide block, which has a trigger button that can be actuated by the foot. If the surfer wants to change the mast position while driving, he must press the release button near the mast foot with his foot and then use the boom to move the mast bow or stern. It should be noted here, however, that the foot is removed from the release button, otherwise it moves along with the movement, which endangers the balance of the surfer.
  • the invention is further based on the object of finding a mast foot mount in which the force required to separate the mast and surfboard body can be individually adjusted with simple means, the mast foot being attached to a sliding block which is in a Slide rail runs, which is embedded in the deck of the surfboard.
  • a device is to be provided which enables the set separating force to be read effortlessly.
  • a movable latching element is arranged inside and parallel to the slide rail, which can engage at different positions with a corresponding counter-formation, which is attached to the slide block, in such a way that it is held stationary. The engagement can be released by moving this latching element.
  • a control device is arranged at the rear end of the slide rail, which comprises the foot-actuated release button and a coupling, by means of which this release button is connected to the locking element for moving it.
  • the release button is thus just before the Sword box of the surfboard, and that near the place where the surfer usually uses his foot.
  • the surfer can unlock the sliding block and then use the boom to move the mast in the desired direction.
  • the mast can be moved past locking positions without it engaging. If the release button is not pressed, the mast moves to the next stop position and then snaps into place.
  • the latching element can in turn have movable pawls which are pulled out of engagement with a rigid counter-formation in the sliding block by longitudinal movement.
  • the latching element is designed as a rod which has notches made on one side at the latching positions. It is now possible to form a rigid nose on the sliding block, which can be brought into engagement with the notches, and to laterally deflect the rod to release the engagement.
  • a pivotally mounted pawl is arranged on the sliding block, which is set up for locking engagement in any latching configuration.
  • the coupling is designed as a rotary drive for the latching rod by such an angle of rotation that the latching designs are rotated out of the engagement area of the pawl or a design on the latching bar presses the pawl out of engagement.
  • the rotatable mounting of the locking rod is easy to carry out, and the rotary drive of the locking rod can be brought about in a simple manner by actuating the release button.
  • the latching rod is arranged next to an inner wall of the slide rail, the latching formations facing away from this inner wall.
  • the locking rod can thus be made relatively thin. A deflection of the locking rod to such an extent that the locking is released automatically is not possible because the locking rod is previously supported against the inner wall of the slide rail.
  • the side surface of the sliding block facing the inner wall is preferably formed with a longitudinal groove which serves to receive and support the latching rod. It is therefore also not possible that the long, self-supporting locking rod vibrates due to rhythmic shocks such as wave shocks and thus releases itself from the rest, because the locking rod is in the immediate vicinity of the locking pawl in the sliding block on which the locking pawl is mounted supports.
  • a particularly simple and reliable solution is that the end of the locking rod is bent over to a drive crank, the free end of which engages in a recess which is formed on the underside of the release button, which in turn is guided in a vertical guide and is pushed up against the force of a spring.
  • the coupling therefore does not require a single separate part, but is only replaced by training the necessary parts.
  • the locking device is designed as a block, which is inserted as an end block in the rear end of the sliding guide.
  • This block is especially made as a plastic part preferably in die casting and has the vertical guide for the release button and a lateral groove in which the end of the locking rod is inserted.
  • a spring is attached between the slide rail and slide block, which prestresses the slide block to the rear. This spring balances the wind pressure that tends to move the sail and mast forward, and ensures that the mast can be easily moved in any direction with the boom at any time.
  • the hidden attachment of the strand spring is preferred, which is achieved in that it is attached to the bu g- sided end of the slide rail, and preferably on an end block inserted into this end, between a longitudinal groove in the slide block and the adjacent inner wall of the Is guided through the slide, is guided over a deflection roller attached to the rear end block and is then attached to the rear end of the slide block.
  • the strand spring is completely covered, has the length required for correct operation, but does not impair the effective use of the entire slide rail for the sliding movement of the slide block.
  • the strand spring holds the two end blocks of the slide rail firmly together, so that fastening elements for holding these end blocks can be dispensed with.
  • the groove for receiving the rubber strand is arranged approximately diametrically opposite the groove for receiving the locking rod with respect to the longitudinal axis; in this way, if there is any play, the strand spring is prevented from displacing the slide block in such a lateral direction that the engagement of the latch with the notches of the latch rod is endangered.
  • the slide block has a vertical bore for receiving the mast foot pin, the tip of which has an annular collar, with a stop for this in the bore and a locking element which is pressed into the bore and is flexible after overcoming a releasing force, which element rests on the stop Raised ring collar.
  • the mast base and thus the entire mast is fixed in its longitudinal direction, since the ring collar of the mast base is stuck between the stop and the locking element.
  • the locking element is flexible after overcoming an adjustable release force, so that it releases the collar and thus the mast foot pin in the event of an overload.
  • the safety fastening according to the invention largely requires the space available within the sliding block, so that this safety fastening could not be used together with the known latching device fitted in the sliding block, since there would otherwise be too long a sliding block for which the available sliding distance in the would no longer be sufficient.
  • the bore is designed as a through bore, the stop being formed by a pin parallel to the longitudinal axis and crossing the bore in the center, which in turn forms the pivot axis for the pawl, which is designed to engage in the locking notches of the locking rod.
  • this pin improves the bending stiffness of the sliding block, which is preferably made of plastic.
  • the locking element can be designed as a locking bolt movable radially to the bore, the direction of movement in the direction of the longitudinal axis of the surf boards is done.
  • the blocking element is a pin which is arranged transversely to the longitudinal axis and is displaceable in the direction thereof and which cuts the bore like a chord. This pin requires the shortest possible lengths, seen in the direction of the longitudinal axis, so that a short sliding block is possible.
  • the pin is supported on its side facing away from the bore on the end of a cap screw which is arranged essentially parallel to the longitudinal axis. This head screw is arranged with its head on the bow side and penetrates with sufficient play an end plate attached to the bow end of the sliding block.
  • the slide block On its shaft, i.e. inside the slide block, it has a compression spring which is supported on the one hand on a nut arranged at the free end of the shaft and on the other hand on the inside of the end plate.
  • the compression spring ensures that the cap screw is always flush with the side of the head facing the end plate and is therefore perpendicular to this end plate with its shaft. If this shaft is deflected transversely to its longitudinal direction, then it automatically returns to the above-mentioned starting position, the magnitude of the restoring force being dependent on the tension of the compression spring, i.e. how far the screw nut is screwed onto the shaft against the compression spring.
  • this nut is non-rotatable in a longitudinal guide, but is axially displaceable relative to the screw, so that one rotation of the screw from the outside is sufficient to increase or decrease the restoring force of the screw, depending on the direction of rotation.
  • a pointer is connected to the non-rotatable nut, which pointer is visible through a window in the top of the sliding block, with markings preferably being assigned to this window, so that the surfer can determine how large by looking at the sliding block the overload required to release the safety attachment is according to the setting.
  • the cap screw and thus also the pusher is arranged on the bow side from the hole for receiving the mast foot so that the pusher is located at a point which, during normal use of the surfboard, is outside the area of action of the foot of the user, especially since it is for the user is no reason in the foot M astsammlung to bring, as the release button for the latching device to move the sliding block is stationary on the rear-side end of the slide and the sword box.
  • the object of the invention is based on the beige added schematic drawing, for example, explained in more detail.
  • a mast foot bracket is shown, which can be attached as a finished assembly in the deck of a surfboard.
  • the mast foot bracket consists of a slide rail 1 with a U-shaped cross-section, in which the free ends of the two lateral legs are angled toward one another.
  • the slide rail 1 is formed from an extruded aluminum profile, which can optionally be pickled to improve the corrosion resistance.
  • a slide block 2 is inserted into the slide rail 1 from one of its ends, the outer contour of which is designed in accordance with the inner contour of the slide rail 1 in such a way that it has only little play, however is effortlessly slidable within the slide rail and is flush at its top with the outer upper edges of the slide rail (see Fig. 2).
  • the sliding block 2 is designed as a plastic part and is described in more detail in FIGS. 4 and 5.
  • the sliding block 2 carries a mast foot 3, which ends in a mast foot pin 4, which in turn is fastened in the sliding block 2.
  • the bow end (in Fig. 1 the left end) of the slide rail 1 is closed by a terminal block 5, which is made of plastic and is partially inserted into the slide rail 1. This part expands like a shoulder in such a way that the outer surfaces of the section protruding from the slide rail 1 are flush with their outer surfaces.
  • the end block 5 has on the port side, lower edge of a recess or longitudinal groove extending over its length, which is dimensioned such that it just allows the passage of a rubber cord 6.
  • This rubber cord 6 is provided outside the slide rail 1 with a thickening, which is formed by turning over and fastening the free end.
  • an actuating device 7 which, as a housing, comprises a housing block 8, which is formed in one piece from plastic and is partially inserted into the interior of the slide rail 1, the part of which protrudes beyond the end of the slide rail is dimensioned such that its outer surfaces are flush with those of the Override the slide rail.
  • the housing block 8 is on the inside of the slide rail lying part on the same side as the rubber cable 6 with a recess which is a little wider than the rubber cable 6.
  • a pulley 9 is rotatably mounted, over which the rubber cable 6 is guided for deflection.
  • the axis of rotation of the rope pulley 9 is designed as a pin which sits in a rotationally fixed manner in the two side legs of the slide rail 1 and the housing block 8 and thus ensures its fastening, while the rope pulley 9 is rotatably mounted on the pin 10.
  • the free end of the rubber cord 6 is connected to a hook 11 which can be hooked into a hook hole 12 (FIG. 2) in the rear end of the sliding block 2.
  • a hook hole 12 FIG. 2
  • the course of the rubber cord 6 is clearly visible from Fig. 1, and it can be seen that the rubber cord 6 seeks to pull the sliding block 2 rearward due to its spring action.
  • the end block 5 can be held in the slide rail 1 by means of fastening pins, but in principle it is sufficient to fasten the end block 5 by the spring tension which is exerted on it by the rubber cable 6 and which endeavors to pull it towards the bow end of the slide rail 1 .
  • a locking rod 13 is arranged near its starboard-side leg, which extends parallel to the slide rail 1 and is rotatably mounted in the end block 5 and in the housing block 8.
  • This locking rod 13 is made of round material and has milled notches 14 which face the sliding block 2 and which extend from mutually parallel and transverse to the slide rail 1 extending side surfaces are limited.
  • FIG. 2 shows a section along line II-II in FIG. 1, the lower run of the rubber cable 6 being shown in section, while the upper run and the hook 11 are omitted.
  • the sliding block 2 adjacent to the rubber cable 6 and the locking rod 13 each have a recess or longitudinal groove, which enables the free sliding movement of the sliding block 2 relative to the rubber cable 6 or the locking rod 13, but in particular this far fixes that no vibration amplitude can form in the area of the block, which would be suitable, for example, to impair the function of the mast foot bracket.
  • the mast foot pin 4 is only shown broken off.
  • the sliding block 2 has a transverse cut 15 (FIG. 5), in which a latch 16 is pivotably arranged about a pin 17.
  • the pin 17 is embedded in the lower part of the sliding block 2 and extends parallel to its longitudinal direction. As can be seen from Fig. 5, the pin 17 extends over the entire length of the sliding block 2 and not only exercises the function of an axis of rotation for the latch 16, but also the function of a stiffener for the entire plastic sliding block 2 and how To be described later, the function of a stop for the lower end of the mast foot 4.
  • the upper part of the detent pawl 16 is supported on a detent spring 18 which is guided in a spring bore 19 (FIG. 5).
  • the detent spring 18 presses the detent pawl 16 towards the detent rod 13, the detent 16 being shaped in such a way that it can fall into one of the notches 14 and with its surface facing the detent rod 13 snugly at the bottom of the respective notch 14 sits on.
  • Fig. 2 the locked position of the latch 16 is shown; thinks now in Fig. 2, the locking rod 13 rotated by at least 90 °, then it can be easily seen that the notch 14 is no longer facing the latch 16, but points up or down.
  • the locking pawl 16 is no longer seated on the base of the respective notch 14, but on the outer circumference of the locking rod 13.
  • the sliding block 2 can be moved effortlessly in the longitudinal direction of the sliding rail 1. If the locking rod 13 is now rotated back into its position shown in FIG. 2, the sliding block 2 continues to move until the locking pawl 16 engages in the next notch 14 and thus prevents further axial movement of the sliding block 2.
  • the mechanism by means of which the locking rod 13 can be rotated by at least 90 ° is designed as an actuating device 7, housed in the housing block 8 and shown in FIG. 3, which represents a section along line III-III in FIG. 1.
  • a vertical guide 20 in the form of a blind hole with a rectangular cross section is formed in the housing block 8 for the release button 21 with an equivalent cross section.
  • this vertical guide 20 is the Trigger button 21 to linear movements along the arrow shown and non-rotatably guided.
  • a return spring 22 is arranged between the bottom of the blind hole and the underside of the release button 21.
  • the release button 21 In its central area, but offset towards the underside, the release button 21 has a recess 23 which is designed as a through hole with a rectangular cross section.
  • crank 24 The end of the locking rod 13 assigned to the actuating device 7 is bent over to form a crank 24, the end of which engages in the recess 23 such that when the release button is actuated in the arrow direction, the crank 24 carries out a pivoting movement in the arrow direction by approximately 90 °.
  • the housing block 8 has a groove 25 formed in the longitudinal direction of the slide rail 1, in which the locking rod 13 is rotatably arranged. Within the movement path of the crank 24, the housing block 8 is recessed in such a way that the movement sequence described can take place undisturbed.
  • the return spring 22 When assembling, the return spring 22 is first to be inserted into the housing block 8, then the release button 21 is to be placed on it and pressed down, and then the locking rod 13 with its crank 24 can be inserted laterally into the groove 25 or the recess 23.
  • the housing block 8 is inserted into the rear end of the slide rail 1, the cable pulley 9 is inserted and the pin 10 is driven in order to close all parts on the slide rail 1 fasten.
  • the mast base is also omitted.
  • the sliding block 2 has on its upper side a mast foot bore 26 into which the mast foot 4 can be inserted with only slight play.
  • This mast foot pin 4 is provided near its free end with an annular recess 27 which is bounded towards the end by a shoulder which projects in the radial direction and which delimits a collar 28.
  • the side of the collar 28 facing the free end of the mast foot pin 4 is chamfered or rounded.
  • the pin 17 already described penetrates the bore 26 diametrically and in the longitudinal direction of the sliding block 2 and forms the stop for the downward movement of the mast foot pin 4 into the bore 26.
  • a locking cylinder 29 is arranged transversely to the pin 17 and protrudes like a chord into the bore 26 on its bow side.
  • the locking cylinder 29 engages behind the collar 28 of the mast base 4. It is essential that the locking cylinder 29 projects into the bore 26 by a smaller amount than the dimension of the radius of the Lock cylinder 29 is.
  • the locking cylinder 29 is preferably formed from a ground steel pin.
  • a cavity 30 is formed on the bow side of the bore 26 and is closed on the end face of the sliding block 2 by an end plate 31.
  • the upper boundary wall for the cavity 30 has a central opening for the passage of a pusher 32, as well as an elongated hole 33 which runs parallel to the longitudinal axis of the sliding block 2 but is laterally offset in this respect.
  • the end plate 31 has an opening approximately at the level of the locking cylinder 29, which is penetrated by the shaft of a cap screw 34 with ample play.
  • the head of the cap screw 34 forms a radial collar adjacent to the shaft, with which it can lie flat against the end plate 31.
  • a square nut 35 is screwed onto the end of the cap screw 34, which is displaceable axially to the shaft in longitudinal guides (not shown in the drawing), but is prevented from rotating.

  • a compression spring 37 is arranged around the shaft of the screw 34 between the pointer part 36 and the inner surface of the end plate 31.
  • the free end of the shaft of the screw 34 is tapered or rounded and is supported against the locking cylinder 29, the central axis of the screw 34 preferably being a little below the central axis of the locking cylinder 29.
  • the force which is to be exerted for pulling out the mast foot pin 4 is directly dependent on the pressure force of the compression spring 37 and thus on the position of the square nut 35, which compresses the compression spring 37 more or less. If the release force is to be reduced, then the screw 34 must be turned counterclockwise, whereupon the nut 35 migrates to the tip of the shaft (assuming a right-hand thread). With opposite rotation, the nut 35 moves in the opposite direction and compresses the spring 37 more.
  • the respective position of the nut 35 and thus the trigger force set in each case can be read directly through the tip of the pointer part 36 in the elongated hole 33, the edge of which can preferably be provided with a scale.
  • the pusher part 32 Arranged between the screw and the upper end wall of the cavity 30 is the pusher part 32, which projects beyond the outer sides of the sliding block 2 and continues inwards into the cavity 30 in the direction of the bore 26. If pressure is exerted on the pusher 32, then it presses on the spring 37 and thus the shaft of the screw 34 in a radial direction thereof, as a result of which the latter is then deflected.
  • the locking cylinder 29 can then easily escape when the mast foot pin 4 is to be pulled out.
  • the mast foot holder shown it is embedded in the deck of a surfboard as shown in FIG. 1.
  • the surfer's foot is located next to or behind the actuating device 7 such that the trigger button 21 can be actuated with the toes.
  • the trigger button 21 is actuated, this rotates the locking rod 13 via the crank 24, which in turn pivots with one of its notches 14 out of engagement with the pawl 16. Now the sliding block 2 can be moved until the release button 21 is released. Then the sliding block 2 moves in the selected direction until the pawl 16 engages in the next notch 14. The sliding block is then fixed in its position.
