EP0653602A2 - Target for darts - Google Patents

Abstract

The dartboard comprises a disc divided by radial spokes (1) and concentric hoops for defining a number of fields, each incorporating a spring-loaded, axially displaced segment (4) and a contact plate (9) with contacts indicating a strike of the respective segment (4). The latter has at least one attached pin (11) brought into contact with the contact plate (9) upon its axial displacement in response to a strike, with a rubber mat (10) between the rear of the segment (4) and the surface of the contact plate (9). An adapter plate (12) fits between the rubber mat (10) and the rear of the segment (4) incorporating bores for each of the pins (11), guiding the axial movement of the latter.

Description

The invention relates to a dartboard according to the preamble of claim 1.

Such a dart target is known, for example, from the older, not prepublished EP-OS 03 54 305.

The object of the invention is to simplify and improve such a dart target.

According to a first proposal, this object is achieved by the features specified in the characterizing part of claim 1. The spokes and / or tires have a wedge-shaped outlet on their front facing the darts. The tip of the wedge points to the front, that is, to the front of the dartboard disc facing the throwing arrows. The spokes and / or tires are wedge-shaped in cross section. This reliably directs a dart hitting a spoke or a tire into one of the adjacent segments.

According to a further proposal, for which protection is sought independently, the object on which the invention is based is achieved in that the spokes and / or tires have inward-facing elevations on their rear sides facing away from the darts. These elevations are preferably spherical (or partially spherical). The thickenings at the rear end of the spokes or tires prevent the segments from falling out when the contact plate is folded away. So if the contact plate has to be folded away for the purpose of maintenance, the Segments do not fall out. The segments can still be replaced to the rear: by pressing the segments from the front, the ribs dodge to the side, and the segments can be removed to the rear for the purpose of replacement.

An advantageous further development of the second proposal is characterized by the features of the solution of the first proposal, that is to say in that the spokes and / or tires have a wedge-shaped outlet on their front side facing the darts.

Further advantageous developments are described in the subclaims.

According to an advantageous further development, the wedge-shaped outlet on the front of the spokes and / or tires is rounded towards the front, ie towards the side facing the darts.

The wedge-shaped outlet preferably has an overlap towards the segment. This reliably prevents the dart from jamming between the spoke or tire on the one hand and the segment on the other. In the case of previously known solutions, the segment could jam and there could be contact problems if a dart hits the air gap between the segment and the spoke or tire. This jamming is prevented by the wedge-shaped runout of the spoke or tire with a small overlap to the segment, so that the problem described does not occur. In this case, it has an advantageous effect if — the contact caps, which will be described in greater detail below — are present on the segments and prevent the segments from “wobbling”. The possibility of jamming an arrow in the air gap between the segment and the rib has been reduced the known solutions namely caused by the fact that the segments in the guides (spokes and tires) wobble. The segments are biased by the contact caps mentioned so that they cannot wobble.

The segments preferably have rear-facing pins, on each of which an elastic contact cap which triggers the hit contact is arranged. This has the advantage that the dart target does not require an elastic rubber mat. Such an elastic rubber mat, which causes the spring loading of the segments and which is relatively expensive, is present in the dart target according to the older, not previously published EP-OS 354 305.

The contact cap can have a further protruding area with which it is constantly supported next to the contact point on the contact plate, and a less protruding area which is spaced apart from the contact point in the rest position and which triggers the contact when hit. In this case too, contact is made directly on the contact plate without a rubber mat. In addition to the contact point, support is provided via the contact cap. The contact point is then contacted when an arrow hits. The dart segment can be removed from the back of the scaffold from the service side.

According to a further advantageous development, the contact cap has one or more elevations resting on the contact plate, preferably three elevations arranged in a triangle being present. The elevations can be spherical.

The contact cap preferably has a forward-facing one Groove that increases elasticity and spring action. The groove can be arranged next to the pin.

A further advantageous development is characterized in that steel segments extending in the transverse direction are provided which protrude beyond the side walls of the segments and which are displaceably mounted to a limited extent in elongated holes in the spokes and / or tires. Here too, the elongated holes of the spokes and / or tires are arranged and dimensioned such that no contact is triggered in the rest position, but that a reliable hit display is guaranteed when a dart hits. The steel axes are preferably connected to the segments by an interference fit. The steel axles then rest reliably in the segments, but can also be removed again if necessary.

The elongated holes can be formed by the rear ends of the spokes or tires. The elongated holes then consist of the area between the rear ends of the spokes or tires and the contact plate or the rubber mat.

At the bearing points of the steel axles in the side walls of the segments, stiffening elevations or projections can be provided. These formations serve to stiffen the segments. This is particularly important if the dart is pulled out of the segment again, since very high forces may then be exerted on the segment and the bearing point of the steel axles in the segments and the spokes or tires. The formations serve to prevent the steel axes from being torn out.

The steel axles preferably protrude beyond the spokes and / or tires by less than the tolerance of the segments within the Fields. In this case the ends of the steel axes cannot interfere with the adjacent segment. For example, the tolerance of the segments within their fields is 0.2 mm. The axial projection of the steel axles over the spokes or tires can then be 0.1 mm, so that there is no impediment to the movement of the adjacent segment.

A contact frame can be connected to the steel axes, on which the pins for contacting the contact plate are preferably arranged in one piece. The contact frame can have approximately the shape of the segment. It is within the segment.

Snap connections for releasable locking with the steel axes can be provided on the contact frame. This allows the contact frame to be easily assembled and disassembled.

A rubber mat can be arranged between the pins and the contact plate. The contact frame can itself be elastic. On the back of the contact frame, in the area of the steel axes, pot-shaped elevations, which rest against the contact plate, can be provided, in the center of which there is a contact elevation which triggers the hit contact. In this case, a rubber mat is not necessary, since the required elasticity is created by the cup-shaped elevations and the contact elevations. According to a further embodiment of the invention, the segments preferably have rearward-facing pins in the vicinity of the steel axes, on each of which an elastic contact cap which triggers the hit contact is arranged. This contact cap can have a further protruding area with which it is constantly supported next to the contact point on the contact plate, and a less protruding area which is spaced apart from the contact point in the rest position and which triggers the contact when hit. Also in this case, the darts segment with its preferably pressed-in steel axles is in turn supported on the spokes or tires. Between the holes provided on the target area of the dart segment, pegs can be injection molded which carry the elastic cap, for example made of elastic, injection molded plastic. The contact is made directly on the contact plate without a rubber mat. In addition to the contact point, there is support via the elastic element of the dart segment or the contact cap. The contact point is then contacted when an arrow hits. The dart segment can be removed from the back of the scaffold from the service side.

According to a further embodiment, the steel axles carry resilient elements, which consist of a first resilient partial element, which rests against the contact plate next to the contact point under pretension in the rest position, and a second partial element, which is spaced apart from the contact point in the rest position and upon a hit triggers the contact. Here too, the dart segment can be removed to the rear, i.e. from the service side. A rubber mat is not required. Each resilient element consists of two sub-elements. The contact plate can be transparent. Another, preferably also transparent, plate can be located behind the contact plate. The arrangement and dimensions are such that a partial element of each spring element always bears against the back plate (contact plate) under a certain pretension. The sub-element lying directly next to it does not abut the contact plate. A system is only created when the segment is hit by a dart, so that the contact is triggered. The multi-layer contact plate (contact surface) is located between the back of the segments and the rear plate. The contacts are arranged in such a way that there are no contacts at the constantly loaded points, but rather there are are located above or below the second sub-elements, which are only pushed back when a hit occurs.

The second sub-element can also be elastic.

The resilient elements can be rotationally symmetrical.

The resilient elements can consist of rubber-like, elastic bodies, preferably of flexible plastic. The resilient elements can consist of two thickened areas with a smaller size or diameter area in between. The use of soft-elastic plastics is particularly advantageous since there are plastics of this type that can be injection molded and thus manufactured particularly easily. The elastic bodies sit on the steel axes that penetrate the segment and protrude from the sides of the segment so that they limit the movement of the segment to the front. An interference fit can be provided between the axes and the segments so that the axes can no longer shift later and possibly interfere with an adjacent segment. Formations for stiffening the segment can be provided on the side surfaces of the segments.

The following advantages can be achieved by the embodiment just described. The segment is preloaded even when the segment is idle. If the second sub-element is also designed to be resilient, the contact surface is protected. In addition, the pressure of an impacting arrow is then distributed over the total area of the two resilient partial elements. Another advantage is that the rubber mat is saved; the elasticity is created by the resilient elements. There are also significant advantages when it comes to assembly: each segment can be fully assembled and will only be then inserted into the scaffold. A complete pre-assembly of each segment is therefore possible before the final assembly on the scaffolding itself. This also has significant advantages in terms of maintenance: if a segment has to be removed, it can simply be removed. In previous solutions, it was necessary to remove at least two strips on the spokes or tires on the back of the scaffold. If the spring elements are used up, the segment can also be easily replaced.

A pre-tensioned segment in the frame is achieved by the pre-tensioning. A practical advantage results from the fact that after a hit the dart does not swing or flutter. In the previously known solutions, there is no pretension because the rubber mat required for the suspension or spring loading cannot be pretensioned there. On the one hand, a pre-tensioned rubber mat would be destroyed by the permanent load at the support points. On the other hand, a hit display would always appear with a pre-tensioned rubber mat. When using a rubber mat, it is not possible in practice to pretension the segments. The rubber mat is available over the whole area and in one piece for all segments and must therefore be designed with a certain minimum hardness (Shore hardness) in order to enable a reliable hit display at all. Accordingly, in the proposed solution, all segments are self-sufficient and equipped with separate elastic elements.

A further advantageous development is characterized by a rubber mat arranged between the contact plate and the back of the segments and an adapter plate arranged between the rubber mat and the back of the segments, which has clearances by the pins for contacting the contact plate are enforced and in which these pins are guided. An adapter plate is provided between the rubber mat and the spokes and tires, and thus also segments, which is distributed over the entire surface of the dartboard, which can also be referred to as a dartboard. The adapter plate has openings or clearances through which the dart segment is pushed through from the operator side, that is to say from the game side (from the front).

The adapter plate preferably has lateral projections with which it is supported on the spokes and / or tires of the frame. The adapter plate can be arranged at least partially at a distance from the rubber mat. Preferably, at least one wire bracket running parallel to the adapter plate on the rear of the adapter plate is provided, which penetrates an elongated hole of the pins. The segments are held to a limited extent by this wire bracket. The elongated holes are arranged and dimensioned such that there is a limited possibility of displacement for the segments. In the rest position, the pins of the segments rest on the rubber mat. The segments are moved towards the rubber mat by a hit, so that the pins can initiate contact on the contact plate through the rubber mat. Then the segments spring back again. The possibility of movement of the segments is limited by the elongated holes and the wire bracket engaging in them. The segments are therefore held by means of the wire bracket.

The wire brackets can be held by hooks provided on the adapter plate and receiving the wire brackets. The hooks preferably have a thickened front area, so that the wire bracket can be snapped into the hook in a detachable manner.

The pins can be integrally connected to the segments, preferably be molded onto them. But it is also possible that the pins are not in one piece with the segments and rest with their front on the back of the segments. The pins are then clamped between the segments and the rubber mat. Parts of the segment which are inserted and formed as ribs or pins or loosely axially displaceable pins thus serve as contactors.

A further advantageous development is characterized by movable slides which are guided on the spokes and / or tires, which engage behind them in a U-shaped manner, and are connected to the sliders, preferably pressed into pins, the guide grooves of the spokes and / or tires and reach through the side walls of the segments, the guide grooves of the spokes and / or tires on the one hand and the segments on the other hand running in opposite directions in an L-shaped manner, so that the pins of the sliders can be inserted into the guide grooves of the spokes and / or tires and locked in place with the guide grooves. The dart segments and the steel spokes have so-called keyholes. The movable slides with the pressed pins are guided on the spokes or tires. The dart segments are inserted from the front into the fields between the spokes and tires and then locked in place via the movable slide and thus locked. They can be unlocked again by moving the slide in the opposite direction and removed towards the front.

The invention can be implemented particularly advantageously by means of spokes and tires made of steel or steel strips. Such steel strips ensure adequate stability of the entire scaffold. Furthermore, they can be made very narrow in cross section, so that the target area can be configured as large as possible.

From GB-OS 22 09 959 a dart target is known in which there are elastic elements on the back of the segments. These resilient elements are rotationally symmetrical and cup-shaped. They rest with their outer edge on the contact plate. When contacting, however, there is not only a deformation of the resilient elements, but also a displacement of the outer edge of the resilient element which bears against the contact plate. This outer edge of the resilient element, which effects the support, must therefore also move outward while overcoming friction.

1 to 3, a first embodiment is shown. The dartboard consists of a frame with spokes 1 and tires 2, which delimit a large number of fields 3 between them, in each of which a spring-loaded segment 4 is axially displaceable is led. The segment 4 has a target area 5 with a large number of holes 6 for receiving the dart, of which only a single hole is shown in FIGS. 2 and 3. 1 shows several, but not all, of the holes. Each hole 6 has a conical widening 7 on the side of the hit surface 5 to make it easier to pick up the dart.

The dart segment 4 is guided axially displaceably within its field 3 lying between the spokes 1 and the tires 2. The direction of the axial displacement is indicated by the double arrow a.

The dartboard consists of a carrier plate 8, a printed circuit board (contact plate) 9 thereon and a rubber mat 10 thereon. The contact plate 9 has contacts for displaying hits for each segment 4. Each segment 4 is at least one pin 11 for contacting the Contact plate 9 assigned to a hit.

Between the rubber mat 10 and the back of the segments 4, an adapter plate 12 is arranged which has clearances 13 which are penetrated by the pins 11 and in which the pins 11 are guided. The adapter plate 12 has lateral projections 14 with which it is supported on the spokes 1 or tires 2. The projections 14 are clamped between the rubber mat 10 and the rear ends of the spokes 1 or tires 2. The adapter plate 12 is arranged at a distance b from the rubber mat 10. On the back of the adapter plate 12 there is a wire bracket 15 running parallel to the latter, each of which penetrates an elongated hole 16 of each pin 11. On the adapter plate 12 hooks 17 are provided which receive the wire bracket 15. In the embodiment shown in FIGS. 1 to 3, the Pins 11 connected to the segments 4 in one piece or injection molded onto them.

The adapter plate 12 lies against the spoke 1 and against the rubber mat 10, as can be seen, for example, from FIG. 3. The spokes 1 and the tires 2 consist of steel strips. The pins 11 are molded onto the dart segment 4 as ribs. Their rear ends are designed as contactors 18. The clearances 16 ensure the mobility of the dart segment. For this purpose, they have an extension in the axial direction a. An expansion perpendicular to this axial direction is also provided for play-free reception. The ribs forming the pins 11 and molded onto the dart segment 4 are arranged between the holes 6. The contactors 18 are in the rest position of the segment 4 on the rubber mat 10. The separate adapter plate 12 has clearances 13 through which the elongated ribs 11 of the dart segment 4 pass. The wire bracket 15 is pushed through the clearances 16 in the segment ribs 4 and holds the segment 4 back on the adapter plate 12 when a dart is pulled out. The wire bracket 15 is held in its locked position by guide channels 19. The hooks 17 also serve this purpose. The adapter plate 12 has lateral projections 14 at suitable points and is supported with them on the steel spokes 1. The clearances 16 in the elongated ribs 11 of the segment 4 are so large (in the a direction) that the wire bracket 15 does not restrict the freedom of movement of the segment 4 required for contacting.

The embodiment shown in FIGS. 4 to 6 corresponds essentially to that of FIGS. 1 to 3. The only difference is that the pins are not formed by ribs which are integrally connected to the segment, but by pins 20 which are not integral with the segments that with their front 21 rest against the back 22 of the segments 4. The ribs 11, in the clearances 16 of which the wire bracket 15 runs, thus end at a distance c in front of the rubber mat 10. The contact is therefore achieved by separate axially displaceable pressure pins 20. The pins 20 are guided in the adapter plate 12 and lie against the dart segment 4 and the rubber mat 10.

7 to 14 show a further embodiment, corresponding parts being provided with the same reference numerals, so that they do not have to be described again. In the segment 4, transverse steel axes 23, 24 are provided, which protrude beyond the side walls 25 of the segments 4 and which are mounted to be displaceable to a limited extent in elongated holes in the spokes 1. The steel axes 23, 24 are connected to the segments by an interference fit. At the bearing points of the steel axes 23, 24 in the side walls 25 of the segments 4, stiffening projections 26 are provided.

In the variants of FIGS. 7 to 10, the steel axes 23, 24 protrude into the adjacent fields 3. In the variants of FIGS. 11 to 14, the steel axes 23, 24 protrude the spokes 1 only by less than the tolerance of the segments 4 within the fields 3. The axis overhang over the spokes 1 can be 0.1 mm, for example, because the dart segment 4 has 0.2 mm tolerance to spokes 1 in each field 3 on each side.

Within the segment 4 there is a contact frame 27 which is connected to the steel axes 23, 24. The pins for contacting the contact plate 9 are located on the contact frame 27. In the exemplary embodiment in FIGS. 7 and 8, the pins 11 are connected to the contact frame 27 in one piece. Snap connections are provided on the contact frame 27 for releasable locking with the steel axes 23, 24. The snap connections exist from segments 28, 29 which extend over an angular range of more than 180 °. The opening directions of the snap connections 28 and 29 are offset by 90 °. The snap connection 28 points outwards, while the snap connection 29 points forward. The contact frame 27 is first latched from behind with its snap connection 28 on the steel axis 23. Subsequently, the contact frame 27 is pivoted clockwise around the steel axis 23 until the snap connection 29 also snaps into the associated steel axis 24. The rubber mat 10 is located between the pins 11 and the contact plate 9. The contact frame 27 is elastic.

The dart segment 4 rests on the steel spokes 1 with the steel axes 23, 24. The contact frame 27 is latched and releasably fastened to the steel axes 23 and 24 by the snap connections 28 and 29.

9 and 10 show a variant of the embodiment according to FIGS. 7 and 8. In the variant of FIGS. 9 and 10, the contact frame 27 is elastic; a rubber mat is therefore not necessary. The dart segment is then supported and reset next to the contact point. In the variant shown in FIGS. 9 and 10, on the back of the contact frame 27 there are provided pot-shaped elevations 30 which rest against the contact plate and in the middle of which there is a contact elevation 31 which triggers the hit contact. The contact elevation 31 is thus located in front of the contact point 32 of the contact plate 9. In the region of the pot-shaped elevations 30, the contact frame 27 also bears against the contact plate 9 when the segment 4 is in the non-operative position. The contact elevation 31 only triggers the hit contact when a dart hits.

11 and 12 show a variant of the embodiment according to 7 and 8. The only difference is that in FIGS. 11 and 12 the steel axes 23, 24 are shortened.

Similarly, the variant according to FIGS. 13 and 14 shows a modification of the embodiment according to FIGS. 9 and 10. The only difference again is that in the embodiment according to FIGS. 13 and 14 the steel axes 23 and 24 compared to the Variant of FIGS. 9 and 10 are shortened.

Another embodiment is shown in FIGS. 15 to 17. Here, too, steel axes 23, 24, which extend in the transverse direction, are provided in the segments 4 and protrude beyond the side walls 25 of the segments 4 and are mounted to be displaceable to a limited extent in elongated holes in the spokes 1. In the vicinity of the steel axes 23, 24, the segments 4 have pins 33 pointing backwards, on each of which an elastic contact cap 34 which triggers the hit contact is arranged. Each contact cap 34 has a further projecting area 35, with which it is constantly supported next to the contact point 36 on the contact plate 9, and a less projecting area 37, which is spaced apart from the contact point 36 in the rest position and which triggers the contact when hit. The elastic cap (contact cap) 34 is attached to the pin 33. The contact cap 34 is supported next to the contact point 36 and presses the dart segment 4 away from the printed circuit board (contact plate). A rubber mat is therefore not required. The dart segment is constantly under tension. A thrown arrow, which strikes the dart segment, moves the dart segment 4 to the printed circuit board (contact plate) 9. Due to the lateral support of the contact cap 34 on its further projecting area 35, this elastic contact cap 34 is arched by the pin 33 and thus leads with its less projecting one Area 37 for contacting the contact point 36 on the contact plate 9. The contacting described by an elastic Contact cap 34 (without rubber mat) can be combined with all retention options for dart segments 4.

In contrast to the embodiment in FIGS. 15 to 17, the variant of FIGS. 18 to 20 has shortened steel axes 23, 24.

In the embodiment of FIGS. 21 to 29, steel axes 23, 24 are again provided which run in the transverse direction in the segments 4. As can be seen from FIG. 21, the steel axes 23 can be bent. The steel axes 23, 24 carry resilient elements 38, which consist of a first, resilient sub-element 39, which rests under prestress against the contact plate 9 next to the contact point 36 (FIG. 23), and a second sub-element 40, which is in the rest position is spaced from the contact point 36 and which triggers the contact upon a hit. In the exemplary embodiment, the second sub-element 40 is also elastic. Furthermore, the resilient elements 38 are rotationally symmetrical. They consist of rubber-like elastic bodies made of flexible plastic. The resilient elements 38 consist of two thickened areas 39, 40, namely the first partial element 39 and the second partial element 40, between which there is an area 41 with a smaller diameter. The resilient element 38 rests under prestress on the contact plate 9, namely at a distance from the contact point 36. When an arrow 42 hits a hole 6 in the segment 4, the second element 40 touches the contact plate 9 at the contact point 36. As can be seen from FIG. 22, the steel axis 23 rests on a trough-shaped depression 43 in the side wall 25 of the dart segment 4. At this bearing point, the steel axis 23 therefore has a certain possibility of displacement. When the arrow 42 is pulled out of the segment, the steel axis is supported on the edge 44 of the spoke 1. The segment 4 is retained in this way. The elastic roller 38 is supported with its large Diameter 39 next to the contact point 36 on the printed circuit board 9; it resiliently rests the dart segment 4 and keeps it under pressure. A thrown arrow 42 moves the dart segment 4 in the direction of the printed circuit board 9, as a result of which the large diameter 39 of the elastic roller 38 is compressed and the small diameter 40 touches the contact point 36 and leads to contact. 22 that only the steel axis 23 bears against the spoke 1, but not the segment 4 or its side wall 25.

In the variant of FIGS. 27 to 29, the steel axes 23, 24 are shortened compared to the embodiment of FIGS. 21 to 26.

Another embodiment is shown in FIGS. 31 to 37. A movable, U-shaped slider 45 engages or engages behind the spoke 1. A pin 46 is pressed into the slider 45. The pin 46 engages on both sides of both guide grooves 47 of the spokes 1 and guide grooves 48 of the side walls 25 of the segments 4. The guide grooves 47 of the spokes 1 on the one hand and the guide grooves 48 of the segments 4 on the other hand run in opposite directions L-shaped, so that the pins 46 of the slider 45 inserted into the guide grooves 47 of the spokes 1 and can be locked with the guide grooves 48 of the segments 4. The latched position is shown in FIG. 30. The dart segments 4 are locked. 31 shows the position in which the U-shaped slides 45 are inserted with their pins 46 into the guide grooves 47 of the spokes 1. The dart segments can then be brought down into position past the pins 46. Subsequently, the slide 45 is pushed to the left, so that the locked position shown in FIG. 30 is reached. The guide grooves 47 of the spokes 1 are open at the bottom in order to be able to insert the slide (FIG. 31). Then the slider 45 is pushed all the way to the right (FIG. 31) around the segments 4 can be inserted into the corresponding fields from above or in front. Then the slide 25 is moved to the left so that the segments 4 are locked by the pins 46.

38 to 41 show another embodiment. The same parts are provided with the same reference numerals as in the previously described exemplary embodiments, so that they do not have to be described again in detail. Segments 4 are guided axially displaceably between the tires 2. The contact plate 9 is located on the rear side of the segments 4 and the tires 2 facing away from the darts 42; again the carrier plate 8 is arranged behind it.

The segments 4 have rearward-facing pins 33 (in the segment 4 shown on the left in FIG. 38, this pin 33 is omitted for the sake of the simplified drawing). An elastic contact cap 34 'which triggers the hit contact is arranged on the pin 33. The contact cap has three elevations 51 arranged in a triangle, with which it already bears against the contact plate 9 in the idle state with prestress. The contact to be triggered by the contact cap lies within the triangle formed by the elevations 51. 38 to 40, only two elevations 51 can be seen in each case, since the third lies in front of the drawing plane. The elevations 51 are spherical, more precisely part-spherical.

On its side facing the darts 42, the contact cap has a forward-facing groove 52, which is realized by a material recess. The groove 52 is approximately semicircular in cross section. It lies next to the pin 33 and increases the elasticity of the contact cap 34 '.

39, segment 4 shown on the right is in the rest position. It is slightly biased by the contact cap 34 '. The segment 4 shown on the left in FIG. 39 is moved backwards by the arrow 42 (in the drawing below), that is to say to the contact plate 9. The contact cap 34 'is deformed toward the contact plate 9, as indicated by the reference number 53. The contact cap 34 'creates the contact through this deformation.

The tires 2 each have a wedge-shaped outlet 54 on their front sides facing the darts 42, the wedge tip pointing forward, ie toward the darts 42. The wedge-shaped outlet 54 is rounded towards the front, as indicated by reference number 55. Furthermore, the wedge-shaped outlet 54 has an overlap towards segment 4. The distance D between the opposite outer corners of the wedge-shaped profile is therefore greater than the thickness d in the remaining area of the tires 2 (and also the spokes not shown in the drawings in FIGS. 38 to 40). The wedge-shaped overlaps 54 are so large that jamming of the dart 42 between the tires 2 (or the spokes) and the associated segment 4 is excluded. A movement of the segments 4 forward is prevented by the projections 14. Starting from the tips 56, the wedge-shaped outlets 44 are rounded inward toward the rear, as indicated by reference number 57.

The spokes 1 and the tires 2 have, on their rear sides facing away from the darts 42, inward elevations 58 which are spherical or partially spherical. These spherical elevations (thickenings) 58 at the rear (lower in the drawing) end of the spokes or tires prevent the segments from falling out when the contact plate 9 is folded away.

As can be seen in FIG. 40 on the basis of the segment 4 shown there on the left, the segments 4 cannot fall out to the rear (in the drawing of FIG. 40 below) even when the contact plate 9 is folded away. It is nevertheless possible to remove the segments: by pushing on the segments 4 from the dart side, the ribs (spokes 1 and tires 2) move sideways, and the segments 4 can be replaced.
