Definitions

  • Such dart target discs are generally known in practice. They are also referred to as darts or darts games.
  • a dart target of the type specified at the outset is intended to include the possibility of an automatic, preferably electrical, hit display.
  • the segments of prior art dartboard discs have pins which are provided on the back of the segments and which are connected in one piece to the segments. For each segment there are several pins integrally molded thereon. The rear ends of the pins come into contact with a printed circuit board arranged on the back of the dart when the corresponding segment is hit by a dart. A corresponding design of the circuit board is then through this contact automatic, electrical hit display possible. Difficulties can arise with the previously known dart target disks if a segment is hit not in the middle but near the edge. In this case, it is possible that the struck segment will tilt due to the eccentric load.
  • Each pin connected in one piece to the segment is in fact guided axially displaceably in a guide of the disk, so that an off-center force application can lead to tilting of the pins in the guides.
  • the pin or pins of the segment hit do not reach the circuit board, that is to say do not trigger any contact.
  • the frame is made of plastic.
  • the spokes and tires forming the frame then have a relatively large strength. This reduces the area remaining for the segments and thus the hit rate.
  • a dartboard according to the preamble of claim 1 is known from US-A-4057 251 or GB-A-2130 107.
  • the structure of these dart targets is made of plastic.
  • a spring-loaded segment is guided axially displaceably in each of the fields delimited by the frame.
  • dart target discs which, in accordance with the previous method of manufacture, consist of a material which is capable of receiving and releasably holding a dart arrow, for example plastic foam, felt, Cork or a mixture of these and compressed sisal fibers.
  • a material which is capable of receiving and releasably holding a dart arrow for example plastic foam, felt, Cork or a mixture of these and compressed sisal fibers.
  • radial and circular wires are defined, which - for example with U-shaped staples - on the compressed sisal fibers can be pinned.
  • a dart target is known, in which the target areas are separated from one another by partitions.
  • the partitions have a wedge edge on the front of the target.
  • the partitions can be made of flat material made of stainless steel.
  • removable inserts made of arrow-holding material are inserted from the rear of the target.
  • the object of the invention is to propose a dartboard disc of the type specified in the introduction, in which the segments are easy to assemble.
  • the spokes and / or tires consist of metal strips which are designed to be resilient so that the segments can be inserted or pressed in from the outside (arrow insertion side) of the dartboard.
  • the metal strips can be made with a relatively small thickness. This increases the area available for the segments. Due to their small thickness, the metal strips offer the chance to achieve a better hit rate compared to the previously known plastic frames.
  • the spokes and / or tires of the framework consisting of metal strips are designed to be elastically resilient, so that the segments can be inserted or pressed in from the outside (arrow insertion side) of the dartboard.
  • the segments can be used from the outside, that is to say from the operator side, since the metal strips of the scaffold spring slightly.
  • the projections or lugs forming stops can have an inlet slope.
  • the projections therefore have an inlet slope on their rear side, so that they can be inserted or pressed in from the outside.
  • the projections have a shoulder on their front side so that they are reliably held in the corresponding recesses. The projections are pressed against the corresponding recesses of the frame with the force of the spring loading of the pins.
  • the frame preferably consists of spokes extending in a radial direction in a radial direction from the center of the dartboard disc, which are connected by concentric, preferably circular tires.
  • the spokes can have recesses into which the tires can be inserted or inserted. It is advantageous if the recesses are punched slightly conically inwards, so that the tires are held in the recesses by friction. During assembly, all tires can then be pushed in and stuck at once.
  • the spokes and tires are preferably rounded on their front. This measure also increases the hit rate.
  • pins are axially displaceably mounted in the frame, the front of which rests against the rear of the segments, the pins being spring-loaded in such a way that they seek to move the segments forward. Due to the spring load, the segments in their rest position are pushed forward into the correct starting position and held there. When a dart hits a segment, that segment is moved backwards. As a result, the pins which rest against the back of the segments with their front side are also moved backwards, against the force of the spring load.
  • the pins are not integrally connected to the segments. Rather, they are axially displaceably mounted in a corresponding guide of the scaffold. If a dart hits the center of the segment, the pins cannot tilt.
  • the segments preferably have stops which limit their forward movement.
  • the pins are stored.
  • the strips are preferably on the back of the scaffold. the metal straps attached. This makes assembly easier.
  • the rear sides of the pins are preferably flush with the rear side of the strips. In this way, the available space is used as much as possible.
  • the strips can contain wire springs that together cushion the axially displaceable pins against the segments.
  • the wire springs can be used in different places. It is crucial that the wire springs are supported on the one hand on the strips and on the other hand on the pins, so that the pins are preloaded in the direction of the segments. It is advantageous if a single spring is provided for a plurality of pins and for a plurality of segments, since the total number of wire springs can then be reduced, that is to say less than the total number of segments.
  • the wire springs can run along the spokes. However, it is also possible to arrange the wire springs along the tires. However, it is also possible to provide a separate wire spring for each pin.
  • pins in one piece these have molded springs, preferably leaf springs. This saves a separate component for the springs. Installation is also easier, since the pins are simply inserted into the corresponding guides of the scaffold or the strips. A single component then takes on both the function of the axial guidance and the function of the spring load.
  • the pins can have a hook-shaped receptacle in which a common elastic wire spring engages for several pins. In this case too, a single spring is used for several pins and possibly for several segments.
  • the back of the pins abut an elastic, preferably transparent mat, preferably made of rubber.
  • the rubber mat is designed so that on the one hand it ensures sufficient suspension of the pins and thus of the segments and on the other hand it ensures a reliable hit display.
  • the transparent rubber mat is also used for light transmission. This makes it possible, for example, to illuminate from behind, which may be desirable, for example, to illustrate the hit display.
  • the segments can have stops or lugs forming stops on their sides, which engage in corresponding recesses in the frame.
  • the projections and the recesses are designed or matched to one another in such a way that the segments in their rest position are flush with the front of the dartboard and that these segments can be moved so far to the rear that the pins can reliably contact the circuit board.
  • the recesses thus generally extend backwards by this required distance, while the projections in this direction are shorter by the required amount than the recesses. It is particularly advantageous in the case of larger or approximately square segments if a projection is provided at each corner of the segment. In the case of narrow or small segments, a projection is preferably provided in the middle of each narrow side of the segment. The projections are used for locking.
  • the pins can be angular in cross section, preferably rectangular, so that they take up as little space as possible.
  • one or more flexible printed circuit boards can be arranged to form the contact point.
  • the segments can have a plurality of holes.
  • the holes of the segments preferably have an inlet slope of preferably 45 ° on their outside (arrow insertion side). This increases the hit rate because the darts penetrate more reliably into one of the holes in the segments.
  • the segments can have a very narrow spray margin.
  • the segments have hook-shaped extensions which form stops and engage behind the framework.
  • This configuration makes it possible to dispense with the otherwise required projections on the sides of the segments and with the corresponding recesses in the frame. Instead of the projections on the sides of the segments, there are hook-shaped extensions on the segments that engage behind the framework. No recesses then have to be provided in the scaffold.
  • the dart disk shown in a detail in FIG. 1 consists of a framework that delimits a large number of fields between them, in each of which a spring-loaded segment (not shown in FIG. 1) is guided axially displaceably.
  • the framework consists of spokes 2, which extend in a radial direction in a radial direction from the center 1 of the dartboard disc, and which are connected by concentric and circular tires 3.
  • the tires are connected to one another at connection points 4 which lie in the area of a spoke.
  • Both the spokes and the tires are made of metal strips, which ensure a better hit rate due to their small thickness.
  • the metal strips are rounded on their front side (shown at the left in FIG. 1) in order to further increase the hit rate.
  • the spokes 2 have recesses 5 on their front side, into which the tires 3 can be inserted or inserted.
  • the cross-sectional shape the recesses 5 correspond to the tires 3.
  • the recesses 5 are slightly tapered inwards so that the tires 3 are held in the recesses 5 by friction.
