Rotation stabilising surfaces for darts

Abstract

The stabilizing surfaces of darts (flights) are designed to stabilize the darts in flight and enable accurate trajectory. If these stabilizing surfaces are damaged or bent, the geometry and aerodynamics are compromised, negatively impacting the dart's flight path. The invention achieves this by imparting a rotating motion around the longitudinal axis to a dart in flight. This rotation generates a gyroscopic effect, which stabilizes the flight path. The rotation facilitates better penetration of the dart into the target and reduces ricochets. Furthermore, the rotational movement allows the thrown darts to glide more smoothly past those already embedded in the dartboard. This rotational effect is achieved solely through deformation, without weakening the stabilizing surfaces with cuts or similar modifications.The deformations make the stabilizing surfaces stiffer, more dimensionally stable, and therefore more durable. The shape is created by bending the stabilizing surfaces (1) along the bending paths (2), thereby creating effective surfaces (3) that generate a rotational movement around the longitudinal axis during flight.

Description

[0001] The present invention relates to a novel stabilizing surface shape for darts.

[0002] Dart arrows are generally known.

[0003] They all have stabilizing surfaces attached to the rear of the shaft, which are called "flights".

[0004] Flights typically consist of four stabilizing surfaces that are connected and mounted parallel to the dart axis.

[0005] A special type is a dart shaft with integrated stabilizing surfaces. Here, the flight and the dart shaft are made from one piece (4) ( Fig. 9 ).

[0006] The stabilizing surfaces have the task of stabilizing the arrows in flight and enabling a targeted flight.

[0007] If the stabilizing surfaces have been damaged through use and improper handling, such as if the surfaces have become uneven or wavy, or if parts have broken off, this has an adverse effect on the flight path.

[0008] Drifting occurs when the geometry or aerodynamics are no longer optimal and the stabilizing surfaces exert an incorrect, steering force on the darts. This can cause the darts to drift in an unpredictable direction.

[0009] In online forums, there are discussions about whether darts with a rotating spin are better or worse. One user has attempted to create the spin by making incisions in the back of the stabilizing surfaces and bending them. However, this damages the stabilizing surfaces. Furthermore, the resulting deformation is too imprecise and uneven, making a consistently good throw nearly impossible.

[0010] Otherwise, no stabilizing surfaces for darts are known that generate a rotational movement solely through deformation.

[0011] The invention specified in claim 1 is based on the problem of designing the stabilizing surfaces in such a way that rotation around the longitudinal axis of the darts is possible in flight without damaging or weakening the stabilizing surfaces with cuts or similar.

[0012] This problem is solved by the features listed in the claims.

[0013] The invention achieves a rotating motion around the longitudinal axis of a dart in flight. This rotation creates a gyroscopic effect, which stabilizes the trajectory. As a result, the darts' flight path becomes more stable, they drift less, and the target is hit more accurately and precisely.

[0014] This is achieved without weakening the geometry of the stabilizing surfaces. Moreover, the modification makes the stabilizing surfaces stiffer, more dimensionally stable, and therefore more durable.

[0015] The rotation helps the dart penetrate the dartboard better and better counteracts a bounce-out.

[0016] The rotational movement allows the thrown darts to glide more smoothly past the darts already stuck on the dartboard.

[0017] This significantly reduces ricochets and severely deflected arrows.

[0018] Another advantage of clockwise rotation is that the screwed-together parts of a dart (5, 6, 7) hold together better.

[0019] This is caused by the inertial energy stored in the right-handed dart. When the dart tip (5) hits the dartboard, this rotation is abruptly stopped. However, the other parts of the dart (6) and (7), driven by inertia, continue to rotate clockwise. Thus, each hit also ensures that the individual parts do not loosen in the thread.

[0020] An advantageous embodiment of the invention

[0021] is described in claim 8.

[0022] The rotational movement now makes it possible to create darts that only have two stabilizing surfaces.

[0023] Without rotation, such an arrangement is never satisfactorily possible, as the stabilizing surfaces always have a tendency in an arbitrary direction and can very strongly negatively influence the flight path, making reasonable flight almost impossible.

[0024] The design with only two stabilizing surfaces offers further advantages.

[0025] With only two stabilizing surfaces, the darts already stuck in the dartboard cover a significantly smaller area than with standard darts that have four stabilizing surfaces. This makes it easier to position subsequent darts very close to the stuck darts without being significantly deflected or bouncing off them.

[0026] Two stabilizing surfaces are also easier and cheaper to produce because less material is used and manufacturing is significantly simpler than with four stabilizing surfaces.

[0027] Because they are also lighter, they can be made of a thicker material. This makes them more stable compared to four stabilizing surfaces without adding weight.

[0028] An embodiment of the invention is described with reference to the Figure 1 bis Figure 10 explained.

[0029] They show: Figure 1 Rotational stabilization surfaces in perspective, side and front view, Figure 2 The possible buckling paths and kinks at the stabilization surfaces, Figure 3 Stabilizing surfaces in perspective view, section view and various cross-sections, Figure 4 Stabilizing surfaces in side and front view, Figure 5 Stabilizing surfaces in side and front view and sectional view, Figure 6 Stabilizing surfaces in side and front view, Figure 7 Asymmetrical stabilizing surfaces in perspective and front view, Figure 8 Stabilizing surfaces in 4-, 3-, and 2-sheet versions. Front view. Figure 9 Dart shaft with integrated stabilizing surfaces, Figure 10 A dart.

[0030] The figures illustrate rotational stabilization surfaces for darts in terms of their structure, variability, and application.

[0031] The stabilizing surfaces (1) are bent along the bending paths (2, 2a, 2b) (21, 22, 23) ( Fig. 1 ) or as a sheet (24) ( Fig. 3 ) formed. Through the kinks (21, 22, 23) and arcs (24), the stabilizing surfaces (1) form a kind of propeller through the resulting effective surfaces (3) which generate a rotational movement around the longitudinal axis of the darts during flight.

[0032] The deformations in the form of kinks (21, 22, 23) and arcs (24) serve not only to generate rotation but also to stiffen the stabilizing surfaces (1), which thereby become stiffer, more dimensionally stable and more shock-resistant and last longer.

[0033] A bend (21, 22, 23) can be made along the bend path (2, 2a, 2b) ( Fig. 2 ) or be shaped like an arc (24) ( Fig. 3 ).

[0034] Depending on the positioning of the kinks (21, 22, 23) or arcs (24) on the kink paths (2, 2a, 2b) the effective area (3) can be varied ( Fig. 4 ).

[0035] By more or less deformations (21, 22, 23, 24) and more or less buckling angles (9) along the buckling paths (2, 2a, 2b) ( Fig. 5 The rotational effect can be increased or decreased.

[0036] Depending on the direction in which the bending or deformation occurs along the bending paths (2, 2a, 2b) ( Fig. 6 ) a rotational effect to the right or to the left is created on the longitudinal axis.

[0037] The stabilizing surfaces (1) are either all the same size and bent and shaped in the same way, or each stabilizing surface (1) has a different size and shape and is individually bent and shaped ( Fig. 7 ).

[0038] The kinks and bends can be placed anywhere and at any angle along the kink paths (2, 2a, 2b) on the stabilizing surfaces (1) ( Fig. 2 ).

[0039] This allows the effect and stability to be adjusted.

[0040] Depending on the positioning and quantity of the applied deformations (21, 22, 23, 24) on the stabilizing surfaces (1), the rotation and flight characteristics of the arrows can be influenced or adjusted.

[0041] The number of stabilizing surfaces (1) can be arbitrary ( Fig. 8 ).

[0042] Reducing the number of stabilization surfaces can result in cost reduction and less material consumption.

[0043] The invention is applicable to all existing products on the market.

[0044] Stabilisation surface forms and also those that will appear in the future.

[0045] All the modifications mentioned can also be made to dart shafts with integrated stabilizing surfaces (4) ( Fig. 9 ) are applied. Reference symbol list
