Device for lifting objects such as wooden boards, planks and suchlike, has flexurally rigid strut with tie rod fitted to each end region and interconnected by upper ends, and angled guide sleeves on strut ends, serving as boring template

摘要

The device consists of a flexurally rigid strut(1) with a tie rod(3a,3b) fitted to each end region and interconnected by their upper ends, and with strut form an isosceles triangle. Angled guide sleeves(5a,5b) are installed on the ends of the strut and serve as a boring template. The longitudinal axes of the guide sleeves intersect at a point lying below or above the strut close to, or the projection of, its centre. Spikes(6a,6b) are fitted in the guide sleeves and after fitting protrude below the strut for angled fitting into holes inside the objects which are bored at an angle as a continuation of the guide sleeves.
