Description

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

[0002] The invention discussed below relates to a device for displaying the positions of tee markers on the surface of a golf course. Hereinafter, the position of a tee marker displayed using the device according to the invention will be referred to as the marker position.

[0003] The teeing area is the area of ​​a golf course from which a golfer begins their round at the start of a hole. The teeing area is rectangular in shape and two club-lengths deep. Its front boundary is defined by the line between the foremost points of two tee markers placed by the tournament officials. The back area is defined by extending the lines from the outermost points of the tee markers two club-lengths backward.

[0004] Within the scope of the disclosure of the invention, a playing direction is defined as the direction in which the player hits the ball or in which direction the player hits or intends to hit the ball with a reasonable probability.

[0005] Research has revealed that a device intended to assist in placing tee markers on golf courses is known from DE 10 2005 203 510 A1. This is achieved by aligning the device with the direction of play and using lasers or poles to indicate the direction in which the tee markers should be positioned. Laser beams or poles are guided parallel to the ground above the surface, but this does not indicate a defined distance between the tee markers. This is only possible with telescopic or removable poles of a defined length. Since the distance between tee markers is typically about four to six meters, the device can only be practically transported between teeing areas with the telescopic poles retracted or removed. This means that the poles would have to be readjusted for each tee shot, which introduces inaccuracies.Aligning the tee markers with the direction of play is not possible with this device. This is probably the reason why this device is practically never used.

[0006] The device described in AT 507 753 A1, while related to golf, is not used for course preparation but rather as a training device that measures parameters of the golf swing. The device uses lights to mark the foot and ball position but is not suitable for positioning tee markers.

[0007] Patent applications DE 10 2007 030 989 A1, DE 297 16 316 U1, DE 10 2007 039 341 A1, DE 10 2007 039 342 A1 and US 3 936 197 A describe devices that use light or laser beams, but cannot be used as described for positioning tee markers. US 8 690 715 B2 discloses a lighting device for projecting field markings onto a playing field.

[0008] According to conventional wisdom, such field markings as, for example, in the Fig. Section 1 of US 8,690,715 B2 is clearly not usable for identifying a unique position. Therefore, US 8,690,715 B2 cannot be considered a document defining the state of the art.

[0009] US 11,161,028 B2 does not disclose a device for determining two points by guiding light beams from a high point to marking positions, wherein the principal axes of the light beams have similar or equal angles to the ground or to a horizontal axis. Unlike the patent application discussed below, the teaching of US 11,161,028 B2 is not limited to creating marking positions at equal or similar distances from the device.

[0010] US 2008 / 0254920A1 discloses the display of playing field markings. Like US 8690715B2, US 2008 / 0254920A1 does not constitute relevant prior art for the device according to the invention.

[0011] WO 2016 / 023 051 A1 reveals that a circle is projected onto the playing field. According to established doctrine, a circle is unsuitable for uniquely marking several individual marker positions on a playing field.

[0012] According to current technology, the placement of tee markers remains an unsatisfactorily solved problem. To a certain extent, the placement of tee markers is subject to the subjective judgment of the member of the tournament committee responsible for setting them, as this is the member who typically assesses the individual positions of the tee markers. The influence of this subjective judgment is partly due to the fact that technical aids are used only to a very limited degree.

[0013] The invention aims to position and, if necessary, align tee markers on golf courses with minimal effort and in a precise and reproducible manner. The method for positioning the tee markers should be as short as possible.

[0014] According to the invention, this is achieved by a device according to claim 1.

[0015] According to the invention, this is achieved by emitting several bundles of light rays through at least one light source, which bundles of light rays are directed from a high point spaced apart from the substrate onto the substrate, wherein several patterns are projected onto the substrate by individual bundles of light rays. where a single bundle of light rays marks a single marker position by a single pattern of the multiple patterns, where each bundle of light rays encompasses a principal axis, which main axis is oriented at an acute angle to the ground and / or to an imaginary horizontal axis, in which marking position a tee marker can be arranged.

[0016] A bundle of light rays with a principal axis is emitted by at least one light source, and this principal axis strikes the surface. A mark is drawn by the bundle of light rays striking the surface, and this mark defines the point of impact with sufficient accuracy. In contrast to prior art methods and devices, the light rays are oriented at an acute angle to the surface. This allows the orientation and distance of the mark position relative to the device, and in particular to the highest point, to be determined by the bundle of light rays. Likewise, multiple mark positions can be defined by using several bundles of light rays relative to each other. Typically, the device according to the invention can indicate two mark positions, each for setting a knock-off mark.

[0017] The acute angle alpha, the angle alpha of the first light ray to the surface, and the acute angle beta can be equal in magnitude. This can be the case, in particular, with a flat and horizontally extending surface.

[0018] The angles alpha and beta can be different.

[0019] The pattern may, for example, and therefore without limitation, have a dot shape, a cross shape, or any other shape known to a person skilled in the art, which shape allows for a sufficiently accurate marking of a point on a substrate according to the prior art.

[0020] The pattern can also include a directional indication. When using the cross shape as a pattern, one leg of the cross can have a longer leg length than the other legs.

[0021] The bundle of light rays can be directed through a lens to indicate the point or marker position. Furthermore, it is possible to indicate the point or marker position using multiple bundles, which together form a geometric shape such as a cross or a circle.

[0022] It is crucial that a main axis of a bundle of light rays passes through a high point spaced away from the ground, and that the light ray is directed at an acute angle towards the ground.

[0023] The principal axes, which pass through high points that are essentially equidistant from the ground in the vertical direction and arranged at a defined distance from each other, intersect the high points at similar distances when projected onto the ground. This is particularly the case if the ground is flat and extends horizontally. A person skilled in the art can compensate for different elevations of the high points relative to the ground or for a ground shape that deviates from the aforementioned ideal case by using different acute angles alpha and beta.

[0024] The device according to the invention can be characterized in that a light beam guiding element and / or light beam focusing element is arranged between the at least one light source and the substrate, and the light beam passes through the light beam guiding element or the light beam focusing element.

[0025] A light beam guiding element can, for example, be an element with a reflective surface. The light beam guiding element can change the direction of a light beam. It can also split a light beam.

[0026] The device according to the invention can be based on the use of laser light. A person skilled in the art can also provide for the use of other types of light, which types of light may require the use of light beam focusing elements in order to indicate the marking position with sufficient light intensity.

[0027] The device according to the invention can be characterized by the fact that A first light source emits a first bundle of light rays, and a second light source emits a second bundle of light rays.

[0028] Using multiple light sources to display a corresponding number of marker positions can have the advantage that no light beams emitted by the light sources need to be shared. The intensity displayed at each marker position can be higher when using multiple light sources than when using a single light source to display multiple marker positions.

[0029] The device according to the invention can be characterized by the fact that a single light source emits multiple bundles of light rays.

[0030] Providing a single light source has the disadvantage that the light rays emitted by the single light source are needed to display multiple Marking positions must be divided. This reduces the intensity of a marking position displayed on the background compared to using multiple light sources.

[0031] The device according to the invention can be characterized by the fact that the device includes a sighting device such as a rear and front sight, a rod, a beam of light or an optical sighting device, which sighting device allows the main axes to be aligned with the direction of play.

[0032] The alignment devices mentioned here as examples are known to those skilled in the art. They may also provide other alignment devices known according to the prior art. The alignment device allows the principal axis projected onto the surface to be aligned with the direction of play. Typically, the principal axis projected onto the surface is oriented at an angle of 90 degrees to the direction of play.

[0033] It is mentioned above that the pattern used to indicate the marking position includes a directional indication. Alignment of the device according to the invention results in alignment of the main axis. Since the By aligning the main axis oriented light beams to give them a defined pattern, an alignment of the direction indicated by the pattern can be achieved by aligning the device according to the invention.

[0034] The device according to the invention can be characterized by the fact that The sighting device is detachably arranged on the device.

[0035] The device according to the invention can be characterized by the fact that the highest point can be adjusted by means of a height adjustment device, which results in a marker position distance, which marker position distance between two The marking positions are measured, the vertical distance of the high point to the ground can be changed, and the height adjustment device can be operated manually and / or by a drive.

[0036] By setting the high points, the distance projected onto the ground between the high point projected onto the ground and the marking position on the ground is changed, while maintaining a constant acute angle.

[0037] The device according to the invention can be characterized by the fact that the acute angle can be adjusted by an angle adjustment device, so that the marking position distance can be adjusted by changing the acute angle of a main axis, the angle adjustment device can be operated manually and / or by a drive.

[0038] By changing the acute angle, the distance projected onto the ground between the high point and the marker position is changed, provided the elevation of the high point remains unchanged.

[0039] The user can adjust the acute angle and / or the height of the high point to change the distance projected onto the ground between the high point and the marker position.

[0040] The surface can be a flat and horizontally extending area. However, such a surface is not feasible in nature and therefore cannot be created on a golf course. The device disclosed herein can also be characterized by the fact that, by setting the elevation of the high point and / or by setting the acute angle, a surface deviating from the ideal shape is taken into account when displaying the marker positions. This can imply that the device according to the invention includes measuring systems for recording the geometric shape of the surface. Furthermore, the device according to the invention can include a processing unit for calculating the acute angle and / or the elevation of the high point, taking the shape of the surface into account.

[0041] The device according to the invention can be characterized by the fact that the device includes a display device, on which display device a change or value of the distance between the highest point and the ground and / or a change or value of the acute angle or the numerical value of the acute angle and / or The pattern spacing will be displayed.

[0042] The display device can show information for manually setting the required actuator. Furthermore, the display device can show the aforementioned information for documentation purposes.

[0043] The device according to the invention can be characterized by the fact that a lighting duration of at least one light source that can be controlled by a time control unit.

[0044] The device according to the invention can be characterized by the fact that which at least one light source, optionally the light beam guiding elements and optionally the light beam focusing elements are arranged on a carrier plate, which carrier plate is rotatably mounted to be locked around at least one horizontal axis, so that the high points and the marker positions are arranged in a plane extending vertically at an angle of 90 degrees to the direction of play.

[0045] A first horizontal axis can be arranged at a 90-degree angle to the direction of play and thus parallel to the main axis projected onto the surface. A second horizontal axis can be arranged at a 90-degree angle to the first horizontal axis.

[0046] The support plate can be mounted to pivot freely about the first axis and / or the second axis. A support plate whose center of gravity advantageously lies below at least one axis will be aligned by gravity. The support plate is thus gimbal-mounted.

[0047] This alignment due to gravity can occur about one or two axes, as is known in other devices according to the prior art. The device according to the invention can have locking means for blocking the rotational movement of the support plate about this axis or these axes. Furthermore, the bearing about the aforementioned axis can also include damping and / or resistance. Resistance, for example, prevents the support plate from being realigned as a result of environmental influences such as wind.

[0048] The device according to the invention can also be characterized in that the support plate is rigidly mounted to a further element such as a housing, which housing is rotatably mounted about at least one horizontal axis.

[0049] The device according to the invention can be characterized by the fact that a laser output device which serves as at least one light source and is cooled by a cooling medium.

[0050] According to established theory, laser light is characterized by a strong focusing and high intensity. For this reason, the use of laser light in the device according to the invention is advantageous. A person skilled in the art could also provide for other forms of light.

[0051] When using a light source different from the laser output device, the person skilled in the art may also provide for cooling this light source by means of a cooling medium.

[0052] The device according to the invention can be characterized by the fact that which at least one light source and, if applicable, the light beam guiding elements and, if applicable, the light beam focusing elements are arranged in a housing, which housing includes light outlet openings, which light outlet openings may be sealed with a transparent material.

[0053] The casing can be waterproof and / or airtight.

[0054] The device according to the invention can be characterized by the fact that The device includes at least one light source, which light source emits light of different colors, and between which colors the user can choose.

[0055] Providing laser light beams of different colors necessitates the use of multiple laser light output devices. The device according to the invention is characterized in that the respective laser light output device is selected along with the type of laser light to be output.
