Abstract

A wind-surf board possesses at least one safety release foot- retaining loop (50) which is fixed to the surface of the surf board (12) in the region in which the surfer stands, in a manner such that the surfer standing on the surf board (12) can place one foot in a foot-receiving space (13) situated under the foot-retaining loop (50), and in the event of disproportionately high stresses on the surfer's foot situated in the foot-receiving space (13), in a direction perpendicular and/or parallel to the board surface (39) of the surf board (12), the foot-retaining loop (50) yields so that the foot is released. According to the invention, the foot-retaining loop possesses at least one rigid bar member (40) which extends above the foot-receiving space (13), at least approximately perpendicular to the direction (42) of insertion of the foot, and is attached to a bearing (11) attached to the board surface (39) adjacent to the foot-receiving space (13) so that it can pivot outwards at least in and/or counter to the direction (42) of insertion against the force of a releasing spring (20). <IMAGE>

Description

The invention relates to a standing sail board with at least one safety release foot retention loop according to the preamble of patent claim 1.

In known standing sail boards, the safety release foot retention loops (EP-B-0 050 878, DE-C-29 45 235, DE-C-30 41 146) are flexible, so that the insertion of the foot into the loop can be problematic if the loop does not have its arched desired shape, but is flattened, for example during transport or by stepping on it, or is at least deformed in such a way that the foot space which is normally available is greatly reduced. It should be taken into account here that several pairs of loops are normally arranged on the surface of a sailing board, so that the surfer can also achieve various foot positions during sailing, which are necessary in different sailing positions and wind conditions.

The aim of the present invention is therefore to provide a standing sail board of the type mentioned at the beginning, in which the intended foot receiving space below the foot strap is always available in full size for the insertion of the foot without the safety trigger function in the event of a fall or other excessive foot stress.

To achieve this object, the invention provides the features of the characterizing part of patent claim 1.

The idea of the invention is therefore to be seen in the fact that at least the holding part of the foot holding loop which extends across the foot is stiff, i.e. is not inherently flexible, so that it can be used both during transport and e.g. when stepping on it always maintains the given straight or slightly curved shape. So that there is no injury to the standing glider due to the rigidity of the rod part or the rod parts themselves, these are resiliently arranged on board-fixed bearing blocks or on a board-fixed bearing block. At least a horizontal swiveling should be given in or against the direction of insertion of the foot.

The release spring or the release springs ensure that the rigid or rigid rod parts always remain in their desired position defining a foot receiving space, unless excessive release forces become effective. After the foot has been released, the trigger spring then either returns the rod parts automatically to their normal position, or this return takes place manually.

Advantageous embodiments of the invention are characterized by the subclaims.

According to claim 2 is triggered only by a pivoting possibility of the full bracket or the partial bracket around the vertical axis.

The measures according to claims 3 and 4 are provided in order to obtain at least a facilitated horizontal release even when the foot is subjected to excessive loads in the direction perpendicular to the board surface.

An advantageous embodiment of the invention is characterized by claim 5.

It is particularly preferred if, according to claim 6, there is also a possibility of triggering in that the foot is released in the event of excessive stresses which are perpendicular to the board surface. In a simplified embodiment, this triggering option can also be provided without the pivot triggering in the horizontal direction.

Advantageous practical embodiments of the invention are defined by claims 7 to 9.

If, according to claim 10, the pivot axis is inclined, a further pivot possibility about the mentioned transverse axis must also be provided.

Further developments of this embodiment are defined in claims 11 to 14.

Optionally, it can also be provided according to claim 15 that the rod parts open substantially horizontally on associated bearing blocks and are resiliently attached there about the desired axis upwards and / or forwards and / or backwards.

This can be achieved according to claim 16 by means of a single rod part 40, which is optionally made in one piece with a bracket part, or according to claim 17 with two preferably axially aligned, rod parts arranged opposite each other.

Fig. 1 shows a plan view of a sail board 12 with a bow 46, a stern 47, a mast foot receiving opening 48, a sword box 49 arranged behind it and eight foot straps 50, of which two are arranged in the longitudinal direction of the board on both sides of the sword box 49, four more, under one Angle of about 45 ° to the longitudinal direction of the board arranged behind the Sword box 49 are located, two in each case one behind the other on both sides of the board central longitudinal axis 51 and two one behind the other on the board longitudinal center axis 51 and extending in the longitudinal direction of the board are provided one behind the other in the rear area. The foot loops 50 shown are flexible in accordance with the prior art; the standing glider can step into one or two loops 50 with one foot or both feet with the foot from the side or obliquely from behind, so that it has a perfect foot hold on the sailing board.

Each of the foot straps 50 shown in FIG. 1 can be designed as described below with reference to the other figures.

In the following description, the same reference numbers always denote functionally corresponding components.

In the first embodiment according to FIGS. 1 to 6, a holding loop 50 consists of two rod parts 40 with their ends 44 arranged at a small distance opposite one another, above the foot receiving space 13, which are part of partial brackets 15 which - starting from the slightly bow-shaped curved downward, but essentially horizontally extending rod part 40 - are increasingly curved downwards, where they open into a neck 15 ', which are pivotally mounted about a vertical axis 16 on a bearing 11 fastened to the surface 39 of the sail board 12. The partial stirrups 15 extend - starting from the ends 44 - in opposite directions. The distance between the necks 15 'is chosen so that the foot receiving space 13 extending between them is sufficiently wide to accommodate the foot of the standing glider. The space between the board surface 39 and the rod parts 40 is corre sponding high enough to create sufficient space for the foot, even in the vertical direction.

The partial stirrups 15 have a stable metal core 15˝, which is coated with plastic 15 ‴ in particular to create a soft footrest surface.

The necks 15 'have a circular cylindrical and perpendicular to the board surface 39 standing, open at the top spring receiving space 23, which merges into a narrow bore 22 going downwards at the bottom. Through the lower bore 22 extends from below a perpendicular to the board surface 39 pivot shaft 24, which is part of the bearing 11 from a fitting 21 which is fixed on the board surface 39.

The pivot shaft 24 is provided in its upper region with an external thread 25, onto which a spring abutment screw 26 is screwed from above, the head of which just fits into the spring receiving space 23. Between the head of the spring abutment screw 26 and the bottom of the spring receiving space 23 extends a release spring 20 formed as a coil spring, which thus presses the necks 15 'and thus the partial bracket 15 in the region of the vertical axis 16 against the fittings 21.

On the top of the fittings 21 three somewhat hemispherical locking projections 18 are evenly distributed over the circumference, which in the normal position shown in FIGS. 2 and 4 in provided on the underside of the necks 15 ', complementary locking recesses 19 engage them, resulting in a total a rotary locking device 17 is formed.

The direction from which the foot is set into the loop 50 is denoted by 42 in FIG. 2.

The foot is inserted into the foot loop 50 in the direction of insertion 42 (FIG. 2) between the board surface 39 and the partial stirrups 15.

All edges of the individual components are rounded so that the canopy cannot injure or hurt anywhere. For this purpose, lateral recesses 52 are also provided in the necks according to the invention, which are adapted to the lateral shape of the set foot.

The mode of operation of the described embodiment is as follows:

If forces act on the partial bracket 15 in the direction of the arrows F in accordance with FIG. 3, the partial bracket 15 is pivoted in the relevant direction of rotation when the rotary locking device 17 is released. The locking projections 18 and the locking recesses 19 disengage, the necks 15 'according to FIG. 5 being removed somewhat from the fittings in the direction perpendicular to the board surface 39 (arrows F1 in FIG. 5).

The opposite pivoting of the two partial brackets 15 takes place e.g. then, when the foot of the standing glider assumes an inclined position within the foot receiving space 13 and, for example, twists somewhat during a backward fall.

The pivoting of the two partial brackets 15 can, however, also take place in an opposite direction to that shown in FIG. 3, so that a universal release of the foot is ensured in the most varied types of falls.

A particular advantage of the embodiment according to FIGS. 2 to 6 is that in the event of a backward fall where the foot of the surfer according to FIG. 5 exerts upward forces F2 on the partial bracket 15, the necks 15 'are under somewhat greater compression of the preloaded release spring 20 move upwards, whereupon the locking projections 18 and the locking recesses 19 more or less disengage. If, in addition to the vertical forces F2 according to FIG. 5, there is a small pivoting moment in the direction of arrows F (or in the opposite direction of arrows F) according to FIG. 3, the partial bracket 15 is triggered horizontally with considerably reduced forces. In other words, the pivoting of the partial brackets 15 about the vertical axis 16, which releases the foot, is made considerably easier if additionally upward forces F2 according to FIG. 5 act on the partial brackets 15.

Thus, although in the embodiment according to FIGS. 2 to 6 it is not possible to swivel the partial bracket 15 upwards, the foot is nevertheless reliably released even in the case of excessive vertical forces, because in this way the side release forces are significantly reduced in the course and in the course of this of a fall, at least small additional forces always occur parallel to the board surface 39.

The head of the spring abutment screws 26 is accessible from above through the upper opening of the spring receiving space 28 and has a screwdriver slot 54 for the rotary adjustment. In this way, the bias of the release spring 20 and thus the release force of the partial bracket 15 can be adjusted.

The fittings 21 are fastened to the surface 39 of the sailing board 12 with screws 53 (FIGS. 2, 3).

2, 3, the partial stirrups 15 are relatively wide in plan view, so that a relatively large contact surface for the foot is available from below. 4 and 5, the partial stirrups 15 are comparatively thin in the vertical direction, however the existing thickness, in particular of the core 15 ', has the stability required for driving with the sail board 12.

2 to 6, the vertical axes 16 and the components assigned to them, in particular the pivot shaft 24, are perpendicular to the board surface 39, the vertical axes 16 and the parts assigned to them in the embodiment according to FIG. 7 have an angle of about 70 ° with the board surface 39, the vertical axes 16 being slightly tilted towards one another in the manner shown in FIG. 7. The fittings 21 and the necks 15 'accordingly have slightly inclined rotating surfaces 55, 56.

The embodiment of FIG. 7 has the advantage that the loop 50 formed by the fittings 21 and the partial bracket 15 takes a flatter course overall, so that a lower design in the area of the necks 15 'and thus a somewhat flatter transition into the board 12th can be achieved. In this way, excessive jumps between the board surface 39 and the partial stirrups 15 are avoided, which reduces the risk of injury to the standing glider.

8 to 12, the necks 15 'of the partial bracket 15 are provided with a spring piston receiving space 29 which is only open at the bottom and in which a spring piston 30 is vertically displaceable. Between the pot the spring piston 30 and the upper wall of the spring piston receiving space 29, the prestressed screw pressure release spring 20 is arranged.

On its underside, the piston has a cutting-shaped locking projection 18 which engages in a complementary locking recess 19 of a spherical projection 27, which extends from the board-fixed fitting 21 upwards to the locking projection 18 and from a pin part 27 'fastened in the fitting 21', an approximately hemispherical part 27 'arranged thereon and an all-round collar 21' above. The hemispherical part 27˝ extends from the peg-shaped part 27 'hemispherical upwards and opens into an upper flat surface in which the locking recess 19 is provided.

The collar 21 'engages behind a on the lower flat and parallel to the surface 39 of the surface of the neck 15' arranged perforated disc 28, the inner bore 57 complementary to the outer circumference of the hemispherical part 27 'in the normal position of the partial bracket 15 according to FIGS. 8 and 10 .

By the release spring 20, the cup-shaped spring piston 30 is pressed with the cutting-like locking projection 18 against the ball projection 27, whereupon due to the reaction force, the stop disc 28 from below on the collar 21 '(Fig. 10). In this way, the normal position of the partial bracket 15 shown in FIGS. 8 and 10 is brought about, in which the foot can be inserted into the foot receiving space (13) in the insertion direction 42 (FIG. 8).

The function of the exemplary embodiment according to FIGS. 8 to 13 is as follows:

When side release forces occur in the insertion direction 42 or in the opposite direction, the partial brackets 15 pivot analogously to the exemplary embodiment 2 to 6 in the direction of the arrows shown in FIG. 9, depending on the direction in which the partial brackets 15 are subjected to forces.

Since the ball projection 27 is non-rotatably fastened to the fitting 21, the latching projection 18 rotates out of the latching recess 19, for which it is necessary, however, that the spring piston 30 is guided in a non-rotatable manner in the spring piston receiving space 29. In the exemplary embodiment shown (FIG. 8), this is achieved in that both the spring piston receiving space 29 and the spring piston 30 have a square cross section.

As soon as the partial bracket 15 is pivoted through 90 ° about the vertical axis 16 (FIG. 12), the latching projection 18 is completely lifted out of the latching recess 19. At this stage, no restoring forces are transferred to the partial bracket 15.

However, before the locking projection 18 has completely emerged from the locking recess 19, restoring moments are exerted on the partial stirrups 15 via the inclined surfaces of the cutting edges, so that an automatic resetting can take place due to the pretensioning of the release spring 20. The desired triggering and restoring moments can thus be influenced by appropriate design of the inclined surfaces of the latching recess 19 and the latching projection 18.

If vertical forces F2 occur on the partial stirrups 15 according to FIG. 10, when the standing glider suffers a backward fall, for example, the partial stirrups can also move according to FIG. 13 about transverse axes 31 running transverse to the partial stirrup plane pivot upwards, the stop disc 28 pivots around the hemispherical part 27˝ of the spherical projection 27 and the spring piston 30 is displaced upwards under compression of the release spring 20. This creates a downward restoring moment, so that after the foot of the standing glider is released, the partial stirrups 15 are automatically pushed back into the position according to FIG. 10. The release spring 20 generates the required restoring torque via the spring piston 30 and the ball projection 27.

The embodiment according to FIGS. 8 to 13 is thus characterized by a further degree of freedom of movement of the partial bracket 15, the additional advantage of the embodiment according to FIGS. 2 to 6 remaining, according to the partial bracket 15 also with a certain lifting of the necks 15 ' the side release force is reduced.

The embodiment according to FIGS. 8 to 13 thus offers an even higher degree of safety in all conceivable falls of a standing glider whose foot is located in the foot receiving space 13 of a foot strap 50 according to the invention.

The embodiment of Fig. 14 to 16a works instead of helical compression springs with an elastic tension band as a release spring 20. This is housed in a downwardly open, upwardly closed spring receiving space 23 of the necks 15 'of the partial bracket 15, with the spring receiving space 23 slightly downward extends conically beyond the diameter of the release spring 20. The elastic tension band forming the release spring 20 has, for example, a circular cross section. It is attached at 58 and below at 59 with one end to the neck 15 'of the bracket 15 and with the lower end within a receiving opening 60 within the fitting 21, which in turn on the Surface 39 of the sail board 12 is fastened with screws 53. Around the receiving opening 60 in the upper region of the fitting 21, a locking recess 19 of square cross-section is provided, the inclined counter surface 32 'for correspondingly inclined side surfaces 32 of a locking projection 18, which is provided around the spring receiving space 23 at the lower end of the neck 15' and also has a square cross section.

In the normal position (Fig. 14, 15) pulls the release spring 20 elastic drawstring due to suitable bias the neck 15 'down against the fitting 21 so that the locking projection 18 comes to rest against the locking recess 19, namely by the oblique and flat, arranged on a square inclined side surfaces 32 firmly rest against the complementary inclined counter surfaces 32 '.

If the partial bracket 15 is now pivoted in the sense of one of the pivoting arrows of FIG. 14, the partial bracket 15 is pivoted about the vertical axis 16 when the triggering force is reached, and the latching projection 18 rises due to the relative tilting of the side surfaces 32 and the counter surfaces 32 ' 16 from the recess 19 more and more upwards. At the same time, a restoring moment is created which tries to pivot the partial bracket 15 back into its normal position.

As soon as the surfaces 32, 32 'are completely disengaged when swiveling (swivel angle of 45 °), the restoring torque is eliminated and the resetting must be done by hand.

According to FIG. 16 a, a height release is also possible by pivoting about the transverse axis 31 if excessive forces F2 (FIGS. 15, 17) act on the partial brackets in the area of the rod parts 40. 16a lifts out of the recess 19 only on one side, while the transverse axis 31 determining the pivoting movement is located on the opposite side due to the presence of the shoulder 61 (FIGS. 15, 16a).

17 to 19, the necks 15 'of the partial bracket 15 are gimbal-mounted on the board surface 39, for which purpose the fitting 21 has a transverse joint 31 which defines the transverse joint 62, from which, in the normal position, perpendicular to the board surface 39, a pivot pin 63 passes through a corresponding vertical bore 64 of the neck 15 'extends through, which has an outwardly radially projecting collar 65 which engages in an extension 66 of the bore 64.

The joint 62 is provided on a guide member 67 rounded at the top, on which the lower surface 68 of the neck 15 'can slide when pivoting about the transverse axis 31.

The resilient mutual bracing of the two partial brackets 15 'is brought about in the embodiment according to FIGS. 17 to 19 in that 40 horizontal spring receiving spaces 23 are provided in each of the approximately horizontally extending rod parts, which are open towards the ends 44 of the rod parts. Within the spring receiving spaces 23 is an elastic pulling band 20 forming the release spring 20, which is fastened at one end at 58 to the one partial bracket 15, then extends through the associated fault receiving space 23 over the gap between the ends 44 to the opposite partial bracket 15 and in whose Spring receiving space 23 extends to a fastening point 59, where it is firmly connected to the other partial bracket 15.

17 and 17a, the elastic tension band forming the release spring 20 in the present case has a flat shape corresponding to the shape of the flat rod parts 40.

In the case of horizontal pivoting movements according to FIG. 17a, the partial brackets 15 can pivot resiliently about the vertical axes 16, the prestressed elastic tension band 20 expanding and thus producing an elastic restoring force for the two partial brackets 15. As soon as the pivoting forces have ceased, the elastically prestressed tension band 20 pulls the two partial brackets 15 which interact with one another back into the normal position according to FIG. 17.

In the event of excessive vertical forces occurring in the direction of the arrows F2 (FIGS. 18, 19), the partial stirrups according to FIG. 19 can also pivot upward about the transverse axes 31, the elastic tension band 20 also expanding.

In all embodiments, where both the partial bracket 15 can be pivoted about a vertical axis 16 and about a transverse axis 31, combined pivoting movements about both axes are also conceivable, so that a combined yielding of the partial bracket 15 in various directions is also possible according to the invention.

As soon as the foot has come free from the foot receiving space 13, the partial stirrups 15 are also released from the release position according to FIG. 19 by the prestressed elastic tension band 20 pulled back into the normal position shown in FIG. 18.

The advantage of the embodiment of FIGS. 17 to 18 is that there is always a closed bracket, which, however, can enlarge or bend in the different directions without having to do without the rigid and rigid design of the partial bracket 15.

A cardan arrangement of the partial stirrups 15 on the board surface 39 is also realized in the embodiment according to FIGS. 20 to 23.

The neck 15 'of the partial bracket 15 is rotatably mounted here on a transverse joint 62 which determines the transverse axis 31 in the form of a flattened transverse pin, which in turn is formed on a pivot bearing block 69 which in turn is rotatably supported about the vertical axis 16 on the board-fixed fitting 21.

Within the partial bracket 15 'in the region of the necks 15' a spring piston receiving space 29 is provided, in which a cup-shaped, as well as the spring piston receiving space 29 slanted spring piston is arranged, which is pressed against the flat 70 of the transverse joint pin 62, by the as Helical compression spring trained trigger spring 20 which is housed biased within the spring piston receiving space 29. On the end of the spring 29 facing away from the flattened portion 70 acts a rotary cam 71 with a square cross section, which can be adjusted from outside by means of a screwdriver head 72 (FIG. 22) into different rotational positions within a circular bore 73. Depending on the rotational position of the rotary cam 71, the off Release spring 20 more or less biased, whereby the release force can be changed.

Furthermore, from each neck 15 'extends obliquely inwards to a locking projection 18 to a provided on the top of the fitting 21 locking recess 19, which is provided next to the pivot block 69, preferably on the side facing the foot receiving space 13.

The slope of the flat 70 and the spring piston receiving space 29 as well as the spring 20 and the direction of movement of the spring piston 30 is selected such that, according to FIG. 21, the spring piston 30 is supported in the direction of arrow F3 by being supported on the flat 70 (FIG. 21). exerts on the relevant partial bracket 15 that the locking projection 18 is pressed into the locking recess 19.

In this way, a pivoting of the partial bracket 15 about the vertical axis 16 is only possible after overcoming a predetermined triggering force, which is sufficient to lift the latching projection 18 out of the latching recess 19, the respective partial bracket 15 also pivoting somewhat about the transverse axis 31 and the spring 20 is compressed somewhat more by the flattened portion 70 and the spring piston 30. This effect is illustrated in FIG. 23, where the left partial bracket 15 is shown in a position pivoted about the vertical axis 16.

In the event of excessive vertical forces F2 (FIGS. 21, 22), the partial brackets 15 are pivoted directly about the transverse axis 31, the spring piston also being pushed back due to the effect of the flattened portion 70 and the trigger spring 20 being compressed. During this pivoting movement, the locking projection 18 also detaches from the locking recess 19.

The particular advantage of the embodiment according to FIGS. 20 to 23 is that the resilient return elements can be accommodated in a particularly compact and space-saving manner and that here too the release force of the height as well as the side release can be determined with a single spring.

24 to 26, the axis of rotation about which the partial brackets 15 can be pivoted is designed as an inclined axis 33 extending at an angle of 45 °, with correspondingly inclined rotating surfaces 36 being provided on the fittings 21, which are located in the region of a latching recess 19 with lateral oblique counter surfaces 32 '. The counter surfaces 32 'are arranged corresponding to a square. Opposite the rotating surface 36 is a counter-rotating surface 35 on the underside of the neck 15 ', which is formed on a locking projection 18 which has complementary oblique side surfaces 32 to the counter surfaces 32'.

A flexible tension member 37 anchored to the fitting 21 extends through a bore 74 of the fitting 21 running through 45 ° through a conically slightly tapering central counterbore 75 into a correspondingly inclined, enlarged spring piston receiving space, at the end of which there is a spring piston 30 with which the other End of the flexible tension member 37 is fixedly connected. The spring piston 30 can slide axially within the spring piston receiving space 29.

Extending between the bottom of the spring piston receiving space 29 and the spring piston 30 is a helical compression release spring 20 which is placed around the flexible tension member 37 and which is under a predetermined preload, as a result of which the rotating surfaces 35, 36 against one another and the detent projection 18 are pressed into the recess 19, the mutually complementary side or counter surfaces 32, 32 'come into firm engagement with each other.

When the partial bracket 15 is pivoted in the sense of one of the arrows in FIG. 24 against the triggering force determined by the release springs 20, the partial bracket 15 pivots about the inclined axis 33, the latching projections 18 being lifted out of the latching depressions 19 analogously to the embodiment according to FIGS 14 to 17 takes place.

At the same time, with excessive vertical forces in the direction of arrows F2, a pivoting movement about the transverse axis against the force of the more and more compressed release spring 20 is also possible (FIG. 26).

When swiveling up, the flexibility of the flexible tension member 37 in the sense of FIG. 26 is used.

Just as in the embodiment according to FIGS. 14 to 17, a flexible tension member 37 with the associated elements according to FIGS. 24 to 26 could also be used, the elastic tension band 20 of FIGS. 14 to 17 can also be used in the embodiment according to FIGS 25 to 26 can be used.

27 to 34, an embodiment is shown in which an inclined axis 33 is also provided for pivoting the partial bracket 15, for which purpose a spring piston 30 is arranged obliquely displaceably within a correspondingly inclined spring piston receiving space 29, which is located on a spring abutment nut 26 ' supports which is penetrated by the threaded part of a spring abutment screw 26˝. The spring abutment screw 26˝ can from an access opening 76 be adjusted to adjust the bias of the trigger spring 20.

The provided in the region of the neck 15 'spring piston 30 acts on the head of a spherical projection 27, which is formed analogously to the embodiment of FIGS. 8 to 13 and also acts accordingly. Instead of the cutting-like locking projection according to the embodiment mentioned above, knob-like locking projections 18 can also be provided on the ball projection 27, which engage in complementary locking recesses 19 on the bottom of the spring piston 30. Accordingly, the rotary locking device 17 could also be designed in the embodiment according to FIGS. 8 to 13.

The mode of action of the spherical projection 27 and the stop disk 28 and the elements interacting therewith in the exemplary embodiment according to FIGS. 27 to 30 corresponds to that of the parts of the exemplary embodiment according to FIGS. 8 to 13 which are identified by the same reference numbers.

The particular advantage of the embodiment according to FIGS. 27 to 30 is that a pivoting movement can take place not only about the inclined axis 33, but also about a vertical axis 16 according to FIG. 28, by partially lifting the bottom of the spring piston 30 off the spherical projection 27 is pushed back against the force of the spring 20, similar to that illustrated in FIG. 30 for a height release.

In other words, the partial stirrups 15 can be deflected in all directions due to the rotationally symmetrical design of the spherical projection 27, so that there is a particularly safe possibility of triggering the foot of the standing glider.

Accordingly, the rotary locking device 17 with the locking projections 18 and the locking recesses 19 in the embodiment according to FIGS. 27 to 30 only has the purpose of ensuring the normal position of the partial brackets 15 according to FIGS. 27 and 29.

Instead, suitable guides could also be provided between the ball projection 27 and the stop disk 18, which on the one hand do not hinder the resilient deflection of the partial brackets 15 in any direction, but prevent rotation of the partial brackets 15 about the inclined axes 33.

31 to 34 show an embodiment in which, instead of two partial brackets 15, only a single full bracket 14 is used, which has the bar part 40, which runs approximately horizontally and parallel to the board surface 39, approximately in the middle above the foot receiving space 13 and which on the one side merges into a bracket part 41 resting on the board surface 39, while a neck 14 'is provided at the opposite end, in which there is a resilient triggering device analogous to the embodiment according to FIGS. 27 to 30.

32 shows a swiveling-out movement about a vertical axis 16, the spring piston 30 being partially lifted off the ball projection 27, but the rotary latch device 17 can also disengage. As in the previous embodiment, however, in the embodiment according to FIGS. 31 to 34, pivoting about the inclined axis 33 does not need to be possible because the specially provided resilient retaining device permits the full bracket 14 to be pivoted out in all directions. A height swing-out movement is shown in FIG. 34.

35, two straight rod parts 40, which are aligned with one another with respect to their longitudinal axis 43, are arranged with their free ends 44 opposite one another. In the end regions facing away from the ends 44, resilient return devices are again arranged analogously to the exemplary embodiments according to FIGS. 8 to 13 or 27 to 30 or 31 to 32, which, however, run horizontally in the present exemplary embodiment, with the ball projection 27 on board-fixed bearings 45 is attached parallel to the board surface 39.

As a result of this arrangement, the rod parts 40 can deflect resiliently both horizontally and upwards or downwards, rotations of the rod parts 40 about their longitudinal axes 43 not harming because, as said, they are rotationally symmetrical.

The pedestals 45 should be pulled to the foot receiving space 13 in the manner shown in such a way that there is a smooth transition to the rod parts 40 arranged above.

The pretensioning of the release spring 20 can be adjusted in that a knurled wheel 26 ist is arranged on the spring abutment screw 26˝ and can be actuated by an annular recess 77 in the outer circumference of the rod parts 40.

The embodiment according to FIG. 36 differs from that according to FIG. 35 only in that instead of the resilient return device according to FIGS. 8 to 13, such a one according to FIGS. 24 to 26 with a flexible tension member 37 is used. In this exemplary embodiment, however, the rotary latching device according to FIGS. 24 to 26 can be dispensed with.

In contrast to that according to FIG. 35, the embodiment according to FIG. 37 only works with a single rectilinear and rotationally symmetrical rod member 40, which is attached to the bearing 11 only on one side by means of a resilient return device analogous to FIG. 35.

The rod member 40 is longer corresponding to the width of the foot receiving space 13 and is opposite with its free end 44 a board-fixed bearing block 45.

Tripping is possible here both in the lateral and in the vertical direction. This embodiment is characterized by particular simplicity and a particularly small number of components. Here too, a resilient reset device analogous to FIG. 36 could be used.

Instead of arranging a bearing block 45 according to FIG. 37, it is also possible, according to FIG. 38, to have the rod part 40 merge into a bow-shaped part 41 which extends down to the board surface 39 and rests there or at a short distance from the board surface 39 ends. In this embodiment, however, a rotary locking device 17 must be provided between the rod part 40 and the bearing 11 in order to ensure proper alignment of the bracket part 41 relative to the longitudinal axis 43 of the rod part 40, similar to that necessary in the embodiment according to FIGS. 27 to 30 is. 38 is similar to that of FIGS. 31 to 34.
