Using a wheelchair with a stick, faced with the problem of movement in ice. After several trials, it was decided to streamline the stick. In its bottom I drilled a series of blind holes with a pitch of about 5 mm. In need of them put an l-shaped rod, the lower end of which extends slightly beyond the rubber tip of the stick, which is also slotted slit. To keep the rod in the groove cut in the tip, helps the clip from the metal strip. Over time statusisa rod moves down hole. V. TROFIMOV, Saint-Petersburg
