Definitions

  • 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.
  • this object is achieved 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 the like 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 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.
  • 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 groove which increases the elasticity and the spring action.
  • the groove can be arranged next to the pin.
  • spokes and / or tires have a wedge-shaped outlet on their front facing the darts.
  • the tip of the wedge in this case points forward, that is to say to the front of the dart target disc which faces the dart.
  • 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.
  • 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. It is advantageous here if — as described above in the first solution to the problem on which the invention is based — contact caps are present on the segments which prevent the segments from “wobbling”.
  • 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. If the contact plate has to be folded away for the purpose of maintenance, the segments cannot 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.
  • 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.
  • 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.
  • 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.
  • the ends of the steel axes cannot interfere with the adjacent segment.
  • 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.
  • pot-shaped elevations which abut the contact plate, can be provided in the center of the steel axes there is a contact survey that triggers the hit contact.
  • a rubber mat is not necessary, since the required elasticity is created by the cup-shaped elevations and the contact elevations.
  • 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.
  • the darts segment with its preferably pressed-in steel axles, is in turn supported on the spokes or tires.
  • 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.
  • the dart segment can be removed from the back of the scaffold from the service side.
  • 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.
  • 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, rather they are located above or below the second sub-elements, which are only pushed back when a hit is made.
  • 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. On the side surfaces of the segments, there may be stiffeners of the segment.
  • each segment can be fully assembled and is only then inserted into the scaffolding. 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.
  • there is no pretension because the rubber mat required for the suspension or spring loading cannot be pretensioned there.
  • a pre-tensioned rubber mat would be destroyed by the permanent load at the support points.
  • a hit display would always appear with a pre-tensioned rubber mat.
  • the rubber mat is namely all-over and in one piece for all segments and must therefore be carried out 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.
  • Another 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 which are penetrated by the pins for contacting the contact plate and in which these pins are led.
  • 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.
  • at least one wire bracket running parallel to the adapter plate is provided on the back of the adapter plate, each of which penetrates an elongated hole in 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 trigger a 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 connected in one piece to the segments, preferably 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.
  • 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.
  • 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, not only is the resilient elements deformed, but instead in addition, also a displacement of the outer edge of the resilient element abutting the contact plate. This outer edge of the resilient element, which effects the support, must therefore also move outward while overcoming friction.
  • 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 displaceably guided.
  • 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.
  • 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.
  • hooks 17 are provided which receive the wire bracket 15.
  • the pins 11 are connected in one piece to the segments 4 or are 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. Your 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.
  • FIGS. 4 to 6 corresponds essentially to that of FIGS. 1 to 3.
  • 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 which rest with their front side 21 on the rear side 22 of the segments 4.
  • 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.
  • 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 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.
  • 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 inward elevations 58 on their rear sides facing away from the darts 42, 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.
