Description

[0001] The invention relates to a dartboard device according to the preamble of claim 1.

[0002] Darts is a throwing game in which darts, typically up to 15 cm long, are thrown at a circular target, the so-called dartboard, with a diameter of typically 34 cm. When a dart hits the target, a score is awarded based on the point of impact.

[0003] Electronic dartboards are also known for automatically recording and calculating the number of hits. These electronic dartboards typically consist of several target sections, an electrical circuit board, and electronic sensors. Each target section has several tabs located on its back. When a dart hits a target section, these tabs are pressed against a corresponding electrical sensor on the circuit board, triggering an electrical signal that determines the number of hits.

[0004] In this context, DE 197 01 781 C2 discloses a device for determining the point of impact of pointed darts on a target. The device comprises a light source located on one side of the target and an optical sensor device located on the opposite side, aligned with the light source. If an arrow hits the target and obscures the light source with its tip, the sensor device generates a measurement signal. An associated evaluation unit uses these measurement signals to determine the exact point of impact of the dart on the target.

[0005] DE 42 07 933 C2 describes a device for displaying and evaluating hits on targets. This device comprises a video camera for recording the target being shot at, a monitor at the shooter's stand for displaying the recorded images, an image analysis computer for evaluating the video data, and an image storage device that stores the complete image of the target after each shot.

[0006] DE 10 2017 113 575 A1 discloses a dartboard with automatic point counting, in which the hit position of darts is determined using image recording technology. For this purpose, at least two, preferably three image recording units are arranged in a plane with the board, whose recording areas overlap. A back plate serves as shielding and provides background images to improve hit evaluation. An evaluation module calculates the score of a dart from the coordinates determined in the images. The board is advantageously made of solid material and the entire assembly is integrated into a box with an opening. An additional mounting frame positions the image recording units precisely around the board. The use of a third image recording unit increases accuracy, especially with overlapping hits.An optional lighting module is mounted on the backplate to ensure better image quality. Scores can be displayed electronically and also transmitted over networks, allowing for remote darts competitions.

[0007] However, the well-known dartboards with automatic scoring have the disadvantage that they are comparatively expensive and complex to manufacture.

[0008] It is an object of the present invention to propose an improved dartboard device.

[0009] This object is achieved according to the invention by the dartboard device according to claim 1. Advantageous embodiments and further developments of the invention emerge from the dependent claims.

[0010] The invention relates to a dartboard device comprising a disc body, a ring body and spacer arms, wherein the disc body is designed to hold darts over their throwing tip.

[0011] According to the invention, a dartboard device is provided that is essentially constructed in three parts. It comprises the board body, which constitutes the actual dartboard. The board body advantageously has different target areas, each with different point values. Furthermore, due to its material or its specific design—for example, as a perforated board—the board body is designed to hold darts that hit the board body with their tip in the position where they hit the board body.

[0012] In other words, the disc body is functionally equivalent to a conventional dartboard.

[0013] According to the invention, it is now provided that the ring body has a plurality of ring elements which can be connected by means of snap-fit ​​connections, and / or that the spacer arms can be connected to the disc body by means of snap-fit ​​connections and / or that the spacer arms can be connected to the ring body by means of snap-fit ​​connections.

[0014] Such snap-fit ​​connections offer significant advantages in the assembly and handling of the dartboard device. In particular, they enable quick and tool-free connection of individual components, significantly reducing assembly time. Furthermore, snap-fit ​​connections also allow for easy disassembly if necessary, which significantly simplifies maintenance, cleaning, and component replacement.

[0015] A further advantage is that snap-fit ​​connections can better compensate for tolerances, which contributes to a robust and stable connection of the individual components.

[0016] In addition, they can be manufactured cost-effectively, for example through injection molding or 3D printing processes, which makes it possible to manufacture the dartboard device under economically attractive conditions.

[0017] Overall, the use of Snap-Fit connections helps to make the dartboard device user-friendly, easy to install and cost-effective.

[0018] According to a preferred embodiment of the invention, it is provided that the disc body has connection zones for connecting the spacer arms to the disc body.

[0019] These connection zones represent defined areas where the spacer arms can be reliably and precisely attached to the disc body.

[0020] This makes assembly easier and ensures precise positioning of the spacer arms, which improves the stability and accuracy of the entire dartboard assembly.

[0021] According to an alternatively preferred embodiment of the invention, the board body can be designed without the specific connection zones. In this case, the connection zones are preferably designed as independent elements of the dartboard device, which can, for example, be attached directly to a wall on which the board body is also arranged. The connection zones are then advantageously arranged at regular intervals radially around the board device. For example, the connection zones can be attached to the wall by means of adhesive or screws.

[0022] According to a particularly preferred embodiment of the invention, it is provided that the spacer arms can be connected to the disc body by means of snap-fit ​​connections.

[0023] The use of snap-fit ​​connections between the spacer arms and the board body allows for particularly quick, easy, and tool-free assembly and removal of the spacer arms from the board body. Furthermore, as already described, snap-fit ​​connections enable a reliable and stable attachment that can withstand a wide range of mechanical stresses during use. Overall, this connection technology improves the flexibility and user-friendliness of the dartboard device.

[0024] According to an alternative particularly preferred embodiment of the invention, it is provided that the spacer arms can be connected to the disc body by means of screw connections.

[0025] The use of screw connections provides a particularly stable and permanently secure attachment of the spacer arms to the board body. Screw connections also enable precise and secure fixation of the components, resulting in high mechanical precision and stability of the entire dartboard assembly.

[0026] According to a particularly preferred embodiment of the invention, it is provided that screw heads of the screw connections can be covered by means of cover elements, wherein the cover elements can be connected to the spacer arms or to the connection zones by means of snap-fit ​​connections.

[0027] These cover elements can be connected to the spacer arms or connection zones using snap-fit ​​connections. This enhances the visual appearance of the dartboard, as the screw heads are not visible. The cover elements also effectively protect the screw connections from dirt and moisture, thus increasing the service life of the components.

[0028] The snap-fit ​​connections also allow the cover elements to be easily attached and removed without additional tools.

[0029] According to a further preferred embodiment of the invention, it is provided that the disc body has a radial inner zone which is designed to hold the darts over their throwing tip, and a radial outer zone which has the connection zones.

[0030] The radial inner zone is specially designed to hold the darts securely above the dart tip. Thus, the radial inner zone essentially functions like a conventional dartboard.

[0031] The radial outer zone goes beyond the functionality of conventional dartboards and features the connection zones already described.

[0032] For example, the radial outer zone can have several struts connected to one another at a first end, with the described connection zones being arranged at the respective second end of the struts. In this embodiment, the radial outer zone can be arranged concentrically and axially behind the radial inner zone. In particular, the radial outer zone can have three interconnected struts in this case and thus correspondingly have three connection zones. The angular distance between any two connection zones is preferably 120°.

[0033] In an advantageous embodiment of the invention, the radial outer zone and the radial inner zone can be formed as two concentric, axially offset discs, wherein the radial outer zone receives and holds the radial inner zone.

[0034] In an alternative preferred embodiment, the disk having the radial outer zone projects beyond the disk having the radial inner zone only in the region of the connection zones. The connection zones are then advantageously formed as lugs that extend radially from the disk having the radial outer zone.

[0035] This results in the advantage that the radial inner zone can, for example, be designed as a conventional dartboard, which is arranged concentrically on the disc designed as the radial outer zone.

[0036] Since the disc designed as a radial outer zone projects radially beyond the disc designed as a radial inner zone, the connection zones are available radially outside the radial inner zone.

[0037] According to a further preferred embodiment of the invention, it is provided that the spacer arms each have at least two arm elements, wherein the arm elements can be connected to one another via snap-fit ​​connections.

[0038] The Snap-Fit connections enable quick, tool-free assembly and disassembly of the arm elements, making replacement processes much easier. Furthermore, this connection technology ensures a reliable and stable connection between the individual arm elements, improving the mechanical strength and overall stability of the dartboard.

[0039] According to a further preferred embodiment of the invention, it is provided that the spacer arms are extended in an axial direction beyond the ring body.

[0040] This allows for increased flexibility in attaching additional components or modules, such as optical image capture or lighting units. The axial extension of the spacer arms allows for optimal and precise positioning of such additional components.

[0041] Overall, this training allows for expanded and versatile use of the dartboard device, which increases its functionality.

[0042] According to a further preferred embodiment of the invention, it is provided that the spacer arms have a receptacle for connection to the ring body by means of the snap-fit ​​connection, wherein a tab is arranged in the receptacle which fixes the ring body axially.

[0043] The tab can, in particular, be partially inserted into the receptacle such that a portion of the tab protrudes from the receptacle and into a corresponding counter-receptacle in the annular body. This allows the annular body to be additionally held, in particular axially.

[0044] According to a further preferred embodiment of the invention, it is provided that axial ends of the spacer arms, which are remote from the disk unit, are designed to accommodate optical image capture modules.

[0045] This allows for precise and stable mounting of the optical modules, which can be used, for example, to automatically determine the position of the darts. Positioning them at the outer ends of the spacer arms also provides an unobstructed view of the dartboard, increasing the accuracy of image capture.

[0046] According to a further preferred embodiment of the invention, it is provided that the annular body has a circumferential LED strip on its radial inner side and / or has a plurality of LED elements.

[0047] These lighting elements ensure even and sufficient illumination of the dartboard, which also improves the detection accuracy of the optical image capture modules, if equipped. The placement of the LED lighting directly on the ring body also ensures good light distribution and reduces distracting shadows on the board surface. Furthermore, the illumination provided by the LED strip or LED elements increases visibility and thus the quality of play for players, especially in poor lighting conditions.

[0048] According to a further preferred embodiment of the invention, it is provided that the ring body has three ring elements, each forming a partial circle of 120°, or that the ring body has four ring elements, each forming a partial circle of 90°, or that the ring body has six ring elements, each forming a partial circle of 60°, or that the ring body has nine ring elements, each forming a partial circle of 40°, or that the ring body has twelve ring elements, each forming a partial circle of 30°.

[0049] All variants allow easy installation and ensure good stability of the ring body.

[0050] According to a further preferred embodiment of the invention, it is provided that the dartboard device has three spacer arms and three connection zones.

[0051] By using three spacer arms, the ring body is optimally aligned and evenly supported relative to the disc body, which also leads to good mechanical stability.

[0052] The uniform arrangement of the connection zones at an angular distance of approximately 120° each also enables simple and quick assembly and precise alignment of the components.

[0053] According to a further preferred embodiment of the invention, it is provided that the axial ends of the spacer arms each have a sleeve for shielding a detection area of ​​the optical image capture modules against glare, wherein the respective sleeve can be fastened to the axial ends by means of a bayonet lock.

[0054] By protecting the detection areas of the optical image acquisition modules from glare, the reliability and accuracy of image acquisition can be improved.

[0055] The bayonet mount allows for tool-free assembly and disassembly. Furthermore, a bayonet mount can also be manufactured using a 3D printing process, for example.

[0056] According to a further preferred embodiment of the invention, it is provided that the annular body is arranged in a plane parallel to the disc unit.

[0057] The parallel positioning facilitates the integration and adjustment of additional components, such as optical detection and lighting units.

[0058] According to a further preferred embodiment of the invention, it is provided that the dartboard device is designed such that the disc body and / or the plurality of ring elements and / or the arm elements and / or the cover elements and / or the connection zones and / or the sleeve and / or the tab can be produced by means of a 3D printing process.

[0059] This manufacturing method offers significant advantages in terms of the flexibility and cost-efficiency of the production process. In particular, 3D printing enables the simple and cost-effective production of complex component geometries that would be difficult or uneconomical using conventional manufacturing methods. Furthermore, this technology also allows for individual adaptations and modifications of the components to meet specific requirements.

[0060] A further advantage is that private users with their own 3D printer are able to produce the dartboard device cost-effectively.

[0061] Even a product with a typically low production run can still be made widely available, as it does not require a manufacturer to produce the dartboard device in series.

[0062] According to a further preferred embodiment of the invention, it is provided that the dartboard device further comprises optical image capture modules and an electronic arithmetic unit and is designed to detect a position of a dart on the board body by means of the image capture modules and to assign a point value to the position by means of the electronic arithmetic unit.

[0063] The dartboard device is thus capable of precisely detecting the exact position of a dart on the board using the image capture modules. The electronic calculation unit then automatically assigns the corresponding point value to this position. This combination of optical detection and electronic evaluation allows for quick, accurate, and reliable determination of hit positions and the associated point values. This eliminates the need for manual point counting, reducing errors and improving the flow of the game.

[0064] According to a particularly preferred embodiment of the invention, it is provided that the dartboard device is further designed to identify a color marking of a dart by means of the image capture modules and to add the point values ​​of darts each with a common color marking by means of the electronic arithmetic unit.

[0065] This feature of the dartboard device enables convenient and automatic scoring for different players or teams, as each player or team can be assigned a specific color marker. This eliminates the need for manual scoring, improving user-friendliness and reducing errors. This ensures a particularly smooth game flow, which is particularly advantageous in competitions.

[0066] This functionality can advantageously be provided in the form of a suitable software algorithm. For example, suitable software algorithms are available online as so-called freeware.

[0067] Preferably, the software algorithm is executed on a personal computer. The operating system can be Windows, Linux, or Mac.

[0068] Alternatively, the software algorithm can also be run on a so-called Raspberry Pi.

[0069] According to a further particularly preferred embodiment of the invention, it is provided that the dartboard device further comprises an optical output module and is designed to optically output summed point values ​​of darts each with a common color marking by means of the output module.

[0070] This feature provides players with an immediate and clear visual representation of their current scores, significantly improving game overview. The visual display allows players to easily read and track their scores at any time without relying on manual recording. This significantly increases convenience and ease of use and contributes to a smooth game flow. Especially in competitions or when playing in larger groups, this improves game organization and reduces the risk of scoring errors.

[0071] The invention is explained below by way of example with reference to embodiments shown in the figures.

[0072] They show: Fig. 1 shows, by way of example and schematically, a possible embodiment of a dartboard device according to the invention in a perspective view, Fig. 2 one of the spacer arms of the dartboard device of the Fig. 1 in a front oblique view, Fig. 3 the spacer arm of the Fig. 2 in a rear oblique view, Fig. 4 shows, by way of example and schematically, another possible embodiment of a dartboard device according to the invention, also in a perspective view, Fig. 5 one of the spacer arms of the dartboard device of the Fig. 4 in a front oblique view and Fig. 6 the spacer arm of the Fig. 5 in a rear oblique view.

[0073] Identical objects, functional units, and comparable components are designated by the same reference symbols throughout the figures. These objects, functional units, and comparable components are identical in terms of their technical features, unless explicitly or implicitly stated otherwise in the description.

[0074] Fig. 1 shows, by way of example and schematically, a possible embodiment of a dartboard device 100 according to the invention in a perspective view.

[0075] The dartboard device 100 of the Fig. 1 comprises a disc body 110, a ring body 120 and three spacer arms 130. The disc body 110 is designed to hold darts (not shown in Fig. 1) over the dartboard's throwing tip, thus functionally corresponding to a conventional dartboard. As can be seen, the ring body 120 is arranged in a plane parallel to the board body 110.

[0076] For example, the ring body 120 consists of a plurality of ring elements 121, which are each connected to one another by means of snap-fit ​​connections.

[0077] For example, the spacer arms 130 are also connected to the ring body 120 by means of snap-fit ​​connections.

[0078] The disc body 110, on the other hand, has connection zones 111 which enable screw connections 131 between feet 133 of the spacer arms 130 and the disc body 110.

[0079] As can be seen, the spacer arms 130 are arranged along an axial direction - in the example of the Fig. 1 upwards - extended beyond the ring body 120.

[0080] The axial ends 132 of the spacer arms 130, which face away from the disk unit 110, are also designed to accommodate optical image capture modules.

[0081] As can be seen further, the disc body 110 of the Fig. 1 is formed in two parts. The disc body 110 has a radial inner zone 112, which is designed to receive the darts via their throwing tip, and a radial outer zone 113, which has the connection zones.

[0082] For example, the ring body 120 has a circumferential LED strip on its radial inner side (not shown in Fig. 1). This allows the target body 110 to be illuminated, which allows for reliable detection of the area of ​​the target body 110 hit by a dart, particularly in poor lighting conditions.

[0083] The dartboard device 100 of the Fig. 1 is designed, for example, such that it can be largely manufactured using a 3D printing process. For example, the radial outer zone 113 of the disk body 110, the plurality of ring elements 121, the spacer arms 130, and the connection zones 111 are manufactured using the 3D printing process.

[0084] Furthermore, the dartboard device 100 comprises, for example, three optical image capture modules, which—as described—are arranged in the axial ends 132 of the spacer arms 130. The optical image capture modules are CCD cameras that enable color capture.

[0085] The dartboard device 100 also includes an electronic calculator (not shown in Fig. 1), which is designed to read camera data from the CCD cameras and, using the camera data, to detect the position of a dart on the target body 110. Furthermore, the electronic arithmetic unit is designed to assign a point value to each detected position of a dart. For example, the electronic arithmetic unit is a so-called personal computer.

[0086] Finally, the dartboard device 100 is also designed, for example, to use the image capture modules (not shown in Fig. 1) to identify a color marking of a dart and to add up the point values ​​of darts with the same color marking using the electronic calculator.

[0087] Fig. 2 shows one of the spacer arms 130 of the dartboard device 100 of the Fig. 1 in a front oblique view.

[0088] The spacer arm 130 comprises a foot 133 which has four openings 135 for receiving screws (not shown in Fig. 2). By means of the screws and the openings 135, the spacer arm 130 can be removably arranged on a connection zone 110 of the disc body 110.

[0089] Also visible is sleeve 140, which is arranged in the axial end 132 of the spacer arm 130 facing away from the base 133. The sleeve 140 shields the detection area of ​​a CCD camera located behind it from stray light and glare, particularly from glare from the surrounding LED strip. The sleeve 140 is detachably connected to the spacer arm 130, for example, by means of a bayonet lock.

[0090] Also visible is a receiving element 134 for a snap-fit ​​connection, via which the spacer arm 130 can be connected to the ring body 120.

[0091] In the receiving element 134, for example, there is also a tab (not shown in Fig. 2), which additionally fixes and secures the ring body axially.

[0092] For example, a groove 141 is also arranged in the receiving element 134, which enables an orderly cable routing for the LED light strip through the receiving element 134 into the spacer arm 130.

[0093] For example, the spacer arm 130 is the Fig. 1 manufactured using a 3D printing process.

[0094] Fig. 3 shows the spacer arm 130 of the Fig. 2 in a rear oblique view.

[0095] Clearly visible in the rear oblique view is a cover 136 for closing an opening for the CCD camera.

[0096] Fig. 4 shows, by way of example and schematically, another possible embodiment of a dartboard device 100 according to the invention, also in a perspective view.

[0097] The dartboard device 100 of the Fig. 4 differs from the dartboard device 100 of Fig. 1 by the formation of the spacer arms 130.

[0098] The spacer arms 130 of the Fig. 4 have a comparatively slimmer design and in particular do not have visible openings 135 for receiving screws.

[0099] To connect the spacer arms 130 to the disc body 110, the connection zones 111 are also adapted to the modified shape of the spacer arms 130 of the Fig. 4 adapted accordingly. For example, the connection zones 111 have a pin element (not shown in Fig. 4) onto which the spacer arms 130 are attached.

[0100] An opening 138 of each spacer arm allows one or more screws, for example two screws (not shown in Fig. 4) which connects the spacer arm 130 attached to the pin element with the pin element of the respective connection zone 111.

[0101] The openings 138 are shown in the illustration of the Fig. 4 are each covered by a cover element 137.

[0102] Thus, the dartboard device 100 of the Fig. 4 no screw heads visible.

[0103] Fig. 5 shows one of the spacer arms 130 of the dartboard device 100 of the Fig. 4 in a front oblique view.

[0104] The spacer arm 130 comprises a foot 133, which, however, has no openings 135 for receiving screws. As a result, the shape of the spacer arm 130 of the Fig. 5 slimmer and than that of the spacer arm 130 of the Fig. 2. Overall, the distance arm 130 of the Fig. 5 more valuable.

[0105] Also visible here is the sleeve 140, which is arranged in the axial end 132 of the spacer arm 130 facing away from the foot 133.

[0106] Also visible is a receiving element 134 for the snap-fit ​​connection, via which the spacer arm 130 can be connected to the ring body 120.

[0107] For example, the spacer arm 130 is the Fig. 5 was manufactured using a 3D printing process.

[0108] Fig. 6 shows the spacer arm 130 of the Fig. 5 in a rear oblique view.

[0109] In the rear oblique view, not only the cover 136 for closing the opening for the CCD camera can be clearly seen, but also the cover element 137, which covers an opening 138.

[0110] The opening 135 serves to fix the spacer arm 130 by means of a screw to a pin element (not shown in Fig. 6). The pin element is a component of the connection zone 111, so that in this case too, the spacer arm 130 is ultimately connected to the connection zone 111 by means of a screw connection.

[0111] The cover element 137 is connected to the pin element by means of a snap-fit ​​connection, for example, and is thus held by it.

[0112] Fig. Figure 7 shows, by way of example, the tab 139 which is inserted in the opening 134 of the spacer arm 130 of the Fig. 5. The tab 139 serves to axially fix the ring body 120 to the spacer arm 130.

[0113] As can be seen, the tab 139 is arranged in the receptacle 134 such that a portion of the tab 139 is connected to the spacer arm 130 by means of a snap-fit ​​connection.

[0114] However, another portion of the tab 139 protrudes from the receptacle 134 and fixes the ring body 120 axially to the spacer arm 130.
