Description

Indoor and Outdoor Golf Putting Mat with Pressure-Controlled Variable Slope Function The embodiments of the present disclosure relate to a golf putting practice mat, and in particular to an indoor/outdoor golf putting mat equipped with a pressure-adjustable slope deformation function that allows the slope to be freely adjusted by air pressure and enables more natural slope changes and a rolling sensation similar to that of an actual green through a multi-layer structure. Generally, golf putting practice mats consist of an artificial turf layer and a rubber or EVA base layer, and are used simply to practice the ball's roll and impact feel on a flat surface. However, most of these existing products consist of fixed slopes or flat structures, which differ significantly from actual putting situations on the field. The putting greens on actual golf courses have subtle variations in slope and undulation depending on topographical factors, grass density, and moisture content. This natural change in gradient is closely related to judging the putting line, distance control, and ball speed control, and acts as a key factor in improving putting skills. Therefore, there has been a demand for technology capable of simulating the characteristics of such actual terrain even in practice mats. In the past, some products have attempted to use inflatable slopes or utilize manual mechanical supports at the bottom to raise only specific sections. However, this structure had the following limitations. First, since the lower air pockets or supports are formed as a single-layer structure, abrupt height differences occur between adjacent sections. As a result, unnatural movements such as "bouncing or rapid acceleration" occur when the ball rolls. In addition, because the deformation of the single-layer air pockets is inconsistent, some sections of the mat surface may lift or sag even under the same pressure. In addition, the air injection port is exposed to the outside, so damage to the pump or valve area is frequent, and the decrease in sealing performance due to repeated injection/exhaustion has been pointed out as a problem. Moreover, since most mats are designed for indoor use only, they are vulnerable to UV rays, temperature changes, and humidity, making them difficult to use for extended periods in outdoor environments. Accordingly, there is a growing need for a structure that can simulate the smooth undulations of actual fields, stably implement various slope shapes, and be used for extended periods even in external environments.
