摘要:
A line striper (10) comprises a sprayer (22) secured to a frame (12), and a guided wheel assembly (30) rotatably mounted to the frame. The guided wheel assembly includes an adjustment disk (62) with screw notches (64) along its outer diameter, an alignment plate (42) coaxially surrounding and abutting the adjustment disk, alignment screws (56) threaded through the alignment plate to engage screw notches on the adjustment disk, and an antirotation lock. The screws set a rotational alignment of the alignment plate relative to the adjustment disk, and the adjustment disk is coupled via a spindle axle (58) to a guide wheel (28). The antirotation lock (52) engages a locking feature (72) on the alignment plate, thereby fixing the orientation of the guide wheel relative to the wheeled frame at an angle determined by the rotational alignment.
摘要:
An outdoor marking product comprising a chlorophyll-based agent for highlighting living greenery. The chlorophyll-based agent can be non-detrimental to the health of the living greenery. When viewed by a viewer at a minimum predefined viewing distance, the living greenery treated with the chlorophyll-based agent can be visibly distinguishable from and shinier than neighboring untreated living greenery. When the viewer is nearer than the minimum predefined viewing distance, the difference in shine and color between the treated living greenery and the untreated living greenery can be substantially unnoticeable.

The invention relates to a method for marking sports field by placing stripes of paint according to a predefined plan via a spraying nozzle on a level playing surface such as grass, gravel, ice, artificial grass or synthetic material field. A robot unit is provided that is configured to move along the stripes according to the predefined plan. The robot unit receives signals from a number of GPS sending units and continuously calculates its current position on the sports field, and uses the current position on the sports field to calculate a set of control signals to two or more movable elements for propulsion of the unit and for controlling the emission of paint. The invention also relates to a robot unit and use of a robot unit for marking fields.

The invention relates to a snow stake tip including: a body (3) extending in an axial direction (L); holding means (7) for resisting a force pulling in an axial direction (L) which are mounted in series around the body (3) between rings (9) that are also mounted in series; and a means (11) for clamping the holding means (7) and the rings (9) along the body (1). According to the invention, the holding means (7) include: a base, in which an opening for mounting series and one or more arms (19, 21) connected to the base are provided, and the rings (9) include an opening for mounting in series that is in communication with a cavity formed in the rings, said cavity receiving the base of the holding means (7) therein; notches that open into the cavity and enable the arms (19, 21) of the holding means (7) to extend relative to the rings (9); and means (41, 45) for rotationally locking the rings relative to one another, which are spaced apart within a single ring (9) vertically in the axial direction (L), such as to control the compression exerted by the clamping means (11) on the base of the holding means (7) between one ring (9) and the next (9) along the series.

The invention concerns an ice hockey rink formed from joined straight and curved sections of dasher board (1a, 1b) surrounding an ice arena, where each section of dasher board comprises a box-shaped base (3) and a sheet upper transparent protective part (4) of flexible plastic material, that standing upright has one lower edge (4a) inserted from above and captivated in a track (5) in the base. In order to achieve an ice hockey rink combination of stability and an energy-absorbing structure that is flexible during impacts and collisions with the dasher board without compromising on the requirement for free and unrestricted view of the ice for the spectators, the upper protective parts (4) of the sections of dasher board are provided with longitudinal stiffeners (13, 13') at their adjacent side edges, and the adjacent stiffeners (13, 13') are united to each other by means of connectors (16).
