A method of mounting at least one spray gun assembly onto an arm of a line striper includes installing a first clamp onto the arm with the first clamp being connected to a first spray gun assembly and the first clamp having an opening. The first clamp is installed onto the arm by placing the arm within the opening of the first clamp without sliding the first clamp onto an end of the arm. The method also includes securing the arm of the line striper within the opening of the first clamp.

A line marking device (1) comprising a cart (2) with at least one steerable wheel (3) and at least two moving elements (4, 5). The steerable wheel (3) is rotatable around its axle (13) and pivotable such that the cart (2) is steered in a desired direction. The line marking device (1) comprises a GNSS receiver (7) or a robotic total station mounted on the cart (2). The line marking device (1) also comprises at least one spray nozzle (8), for marking a line, which is mounted on the cart and directed towards the ground below the line marking device (1). The device (1) comprises an interface mounted on the cart for a comparator to compare a detected location by the GNSS receiver (7) to a predetermined pattern. The cart (2) may comprise a motor (14) which is adapted to pivot the steerable wheel (3) towards an intended movement.

A display device for displaying a marking in the form of a distance to be kept between game equipment, in particular a football, and a participant on a playing field of a sports facility, includes a display device for projecting light beams representing the marking onto the playing field. The projected light beams display the distance to be kept, and can be projected at least in sections in the shape of a circle, for example at a distance of 9.15 m, around the game equipment on the playing field. The display device is jointly movable with a transport device that is movable above the sports facility.

A pre-visualization device (10) for movie, game, and other digital media creation, the pre-visualization device (10, comprising: one or more markers (13); a motion capture camera system (14); wherein the one or more marker(s) (13) is/are adapted to be physically located and moveable on a marker plane (12), wherein each marker (13) comprises means (13a) adapted to provide position data in relation to its position (P) on the plane (12), the position and possibly movement is captured using the motion capture camera system (14).

A pre-visualization device (10) for movie, game, and other digital media creation, the pre-visualization device (10, comprising: one or more markers (13); a motion capture camera system (14); wherein the one or more marker(s) (13) is/are adapted to be physically located and moveable on a marker plane (12), wherein each marker (13) comprises means (13a) adapted to provide position data in relation to its position (P) on the plane (12), the position and possibly movement is captured using the motion capture camera system (14).

A sports field marking assembly and method of marking creates a boundary reference point and field lines on a field or for coaching. The assembly provides a marker anchoring device that is loaded with field markers. The marker anchoring device comprises a translatable handle coupled to a spring-loaded piston that discharge the field markers into the surface of the sports field. Bristles couple to a rear end of the marker body for visibility above the surface of the field. A tape canister couples to the marker anchoring device to dispense a measuring tape. The measuring tape couples to the field markers, serving to delineate the boundaries and lines on the field. Multiple aligners anchor into the sports field to retain the measuring tape in the formed patterns. The aligners have collapsible and moveable guide posts that can be selectively raised to guide the measuring tape though the chosen guide posts.

A line stripe includes a frame, a mounting arm extending from the frame, a G-shaped clamp, a vertical bar, an extension bar, and a spray gun. The G-shaped clamp has an opening through which the mounting arm is able to extend and a fastener configured to secure the mounting arm within the opening. The opening allows the first clamp to be mounted and then secured on the mounting arm without relative sliding between the first clamp and the mounting arm. The vertical bar is attached to and extends from the clamp. The extension bar is attached to and extends from the vertical bar, and the spray gun is attachable to the extension bar. The clamp is configured to be installable upon and removable from the mounting bar without having to remove similar G-shaped clamps from the mounting bar.

Described herein is a modular skate system that includes at least one modular skate component comprising a major surface, a core comprising a body formed from a first material, an outer layer formed from a second material, the outer layer surrounding at least a portion of the core, wherein the first material is different from the second material, and wherein the major surface comprises the outer layer.
