Definitions
- the invention relates to a sail board with a recess into which a tongue of the mast foot articulated to the mast can be inserted, with a recessed step being provided in a wall of the recess, below which, after the tongue is inserted, a step against it Spring force snaps in cams so that the tongue engages and can be pulled out of the recess after overcoming the spring force.
- mast foot is inserted with a tongue or a peg into a corresponding recess in the sailing board, so that it can be lifted by lifting the mast without overcoming and separated from the sailing board.
- mast base and sail board meet the requirement that the mast base should be able to be easily detached from the sail board in order to prevent body parts of the surfer from being dangerously trapped between the mast and the sail board.
- this loose connection often leads to an unwanted separation of mast and sail board, which makes handling the device more difficult when surfing.
- a mast foot for a sailing board according to the preamble of claim 1 is known, which is releasably locked in a sleeve of the board hull and has resiliently adjustable locking members, the resilience of the locking members being adjustable from the outside by means of a handle.
- a longitudinal adjustment of the mast base is not possible with this version.
- a mast foot holder which has a support member which is held in a carriage which is longitudinally displaceably guided in a slot in the board and can be locked in position.
- a longitudinal adjustment is also possible while surfing, but not a separation of the connection between mast foot and sail board in the event that body parts of the surfer are dangerously caught between mast and sail board.
- the object of the invention is therefore to provide a connection between mast foot and sail board, which ensures a separation of the two parts in the event of danger, avoids an unwanted falling apart of the two parts and is also longitudinally adjustable during surfing.
- the recess consists of a groove in the longitudinal direction of the board serving as a mast track, the length of which is greater than the width of the tongue, that the recessed step extends parallel to the upper side of the board over a longitudinal side wall of the groove and that in a longitudinal side wall the groove is arranged at right angles to the step and is provided for engaging a projection provided on the tongue and which can be pressed in against spring force.
- This configuration enables the mast base to be moved in the longitudinal direction of the board in accordance with the respective wind and water conditions, without having to put down the rig.
- the spring force is chosen so that on the one hand the tongue is pulled out of this holding recess when the mast falls down with the clamping of members of the surfer, but on the other hand the mast base is so firmly locked in the recess that it is during the usual surfing occurring loads there is no separation of mast foot and sail board.
- the mast foot is provided with a push button or a pedal for pressing in the projection.
- a preferred embodiment of the invention provides that a push button is provided which consists of a slider passing through the widened head piece of the mast foot in a transverse opening and in the direction of the recess, and that the slider is actuated from both sides of the mast foot at both ends is provided with thrust pieces which is held in the region of its central position by the resilient device which loads the protruding protrusion and releases the locking mechanism when it is moved therefrom.
- the extractable projection can consist of a spring wire, one end of which is attached to the tongue and which, in its latched position, lies so centrally between oppositely inclined wedge-shaped edges of the slide that it is lifted when it moves in one direction or the other.
- the slide can be connected to a strip with a V-shaped cutout, the flanks of which form the wedge-shaped edges.
- One end of the spring wire is expediently fastened in a lever which is pivotably mounted in the tongue and carries the latching cam which fixes the mast foot in the axial direction.
- only one spring wire is required to lock the mast base in both the axial and transverse directions.
- the sail board 1 is provided with a longitudinal groove-shaped depression 2, the length of which corresponds to the area in which the mast should be displaceable.
- a recessed step 3 running parallel to the top of the board is provided.
- the opposite flank is provided with locking grooves 31 which run at right angles to step 3.
- the mast base 5 has a substantially T-shaped cross section, the central web forming a tongue 6 which can be inserted into the groove 2 and which has a recess in which a lever 10 is pivotably mounted about a bearing pin 9 fastened in the lower region and which is provided with a locking cam 11.
- the locking cam 11 is formed by a step in the lever 10 and has an upper chamfered cam surface 12.
- the lever 10 is cranked in its upper region and provided with a leg 13 which runs approximately parallel to the tongue 6 and which projects into a recess 14 in the upper part of the mast base.
- the upper base of the mast base is also provided with a bore in which a compression spring 15 is arranged.
- the compression spring 15 is supported with one end on the leg 13 of the lever 10 and with its other end on an axially displaceable but non-rotatably guided spring plate 16, which is provided with a thread for an adjusting screw 17.
- the set screw 17 protrudes with its head 18 out of the narrowed end part of the bore and is supported against the inner annular end wall of this end part by a collar 20. By turning the adjusting screw 17, the bias of the spring 15 can be changed.
- the spring plate 16 is provided with an extension forming a pointer 21, which projects into a window 22 of the base of the mast base 5, the edges of which are designed as scales 23 for indicating the set spring force.
- the tongue 6 and the lever 10 are fork-shaped in their lower region with a recess 24, 25 which is closed by the bearing pin 9. This configuration forms an eyelet in which a safety line can be attached.
- a rubber part 26 is attached to the base of the mast base 5, which forms the joint on all sides between the mast and the mast base.
- the width of the tongue 6 corresponds to the width of the groove-shaped recess 2, so that after the tongue has been inserted into the groove-shaped recess 2, the mast foot is fixed therein.
- the base of the mast foot 5 is supported with its lower sides 26, 27 on the surface of the sailing board.
- the leg 13 of the lever 10 is provided with an outwardly projecting button 28, by the actuation of which the latching of the cam 11 on the step 3 can be released.
- the locking mechanism securing the mast foot against displacement in the longitudinal direction of the board consists of a spring wire 30, one end of which is fastened in the tongue 6 and the other end of which is fastened in a push button 29 which is mounted in the base of the mast foot 5 so as to be longitudinally displaceable to a limited extent.
- the spring wire 30 is provided with an arcuate part which engages in the locking grooves 31 of the one flank of the groove 2.
- the push button 29 must be actuated.
- the push button 29 can also be replaced by a pedal which is expediently arranged on the base of the mast base 5 so that the surfer can actuate it with the foot during surfing and can move the mast in the desired manner.
- the spring wire 30 can also be fastened with its lower end to the lever 10, so that it also acts resiliently on the locking cam 11.
- the sail board 101 is provided with a longitudinal groove which forms the cutout 102 for holding and longitudinally displacing the mast base 103.
- a recessed step 104 running parallel to the top of the board is provided in a side wall of the recess 102.
- groove-shaped grooves 105 are provided at a distance from one another, which run in transverse planes perpendicular to the recess 102 and are inclined to the central plane of the recess 102 in such a way that they cut only the upper region of the side wall.
- the mast foot 103 has a substantially T-shaped cross section, the central web forming a tongue 106 which can be inserted into the cutout 102.
- the tongue consists of lateral and parallel webs 107, 108, which are connected at their lower end by a bearing pin 109, on which a lever 110 is pivotally mounted.
- the lever 110 is provided with a locking cam 111 formed by a step, which snaps behind the shoulder formed by the recessed step 104 after insertion into the recess 102 in the manner shown in FIG.
- the webs 107, 108 are fastened in the head part 112 of the mast foot forming a base.
- the head part 112 is essentially cuboid.
- the lever 110 is angled in the manner shown in FIG. 5 and carries on its upper angled leg 113 a push button 114 which passes through a side wall of the head part 112 in a recess so that it can be actuated from the outside.
- a spring wire 115 is fastened in a bore of the lever 110 in the manner shown in FIG. 5.
- the upper part of the bore is rounded in order to allow the spring wire 115 to bend freely.
- the spring wire 115 engages with pre-tension in the groove-shaped grooves 105 of the side wall of the recess 102. In this way, it serves both as a catch that prevents displacement of the mast foot 103 in the longitudinal direction of the sail board, and as a spring acting on the lever 110 that ensures the vertical catch of the mast foot 103.
- the head part 112 is provided with a breakthrough that completely penetrates it, in which the slide 116 is mounted so as to be longitudinally displaceable.
- the slider 116 is provided with a central web part 117, to which a strip made of steel 118 is screwed, which in the manner shown in FIG. 9 has a V-shaped cutout which forms a triangular opening with the web part 117.
- the upper end of the spring wire 115 engages at least partially through this triangular opening in such a way that when the slide 116 is moved in one direction or the other it comes into contact with one of the wedge-shaped flanks 119, 120 of the V-shaped recess and thereby is lifted out of the grooves 105.
- pushbuttons 121, 122 are fastened, on which pressure can be exerted, for example with the foot, to release the latching and to move the mast foot in the longitudinal direction.
- the upper end of the head part 112 is provided with an annular peripheral bead 124, which forms part of a universal joint connecting the mast to the mast foot 103, which has been described in more detail in PCT application WO-A-80/00117 from October 24, 1980 .
- a transverse bolt 125 is fastened in the head part 112 and serves to anchor a rubber band 126 which holds the mast base 103 together with a complementary connecting part of the mast.
- guide ribs 127, 128 are provided on the sail board 101, which are covered by guide grooves 129, 130 in the inserted state of the mast base, which are located on the underside of the head part 112 of the mast base.
- the guide ribs 127, 128 and the grooves 129, 130 ensure a tilt-free displacement of the mast base.
