  "description": "陸上練習施設・体育室の走高跳区画を表す、横バー・二本の支柱・着地マットの一式。伸縮式に見える角形支柱、固定ノブと無番号目盛り、バー受けと両端キャップ、接地するT字脚、三分割の厚い積層マット、上面継ぎ目と側面取手を造形。全部を合わせて1点で、選手・競技場床は含みません。高さ調整・落下・反発などの動作はなく、競技規格・衝撃吸収・実用品安全性は未検証です。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）4.900 × 2.177 × 3.642 m、13,072三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A high-jump bar, twin-upright and landing-mat assembly for athletics practice facilities and gymnasium scenes. It has telescoping-looking square uprights, fixed knobs and unnumbered ticks, crossbar shelves/end sleeves, grounded T-feet, thick three-section layered mat, top seams and side handles. All parts count as one model; athletes and venue flooring are absent. Height adjustment, bar dropping and rebound behavior are absent; competitive specifications, impact absorption and real-equipment safety are unvalidated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 4.900 × 2.177 × 3.642 m; 13,072 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
