AI Technical Summary

Technical Problem

Conventional morning glory devices require simultaneous manipulation of a string and a locking pin to adjust the elevation angle, which is difficult and physically demanding, and lack secure fixing of the angle, risking material displacement in strong winds.

Method used

A morning glory apparatus with a mounting base, diagonal members, and a brace member system that allows easy elevation angle adjustment using an engagement pin and locking grooves, and incorporates a blow-up prevention mechanism.

Benefits of technology

Enables single-person easy adjustment of the elevation angle and maintains it securely, preventing material displacement even in windy conditions.

Abstract

To provide a falling object protective apparatus allowing an elevation angle of surface material to be simply changed even for one personnel work.SOLUTION: An engaging pin 34 having a lateral shaft part projected at least with a length penetrating through a chin resting material connection member 32 in right and left directions is attached on a base end part of a chin resting material 24. A guide groove 36 extending in a vertical direction and capable of passing the shaft part of the engaging pin 34 is formed in a chin resting material connection plate 32a, and at a plurality of predetermined height positions in the guide groove 36, engaging grooves 38 for elevation angle adjustment extending obliquely forward and downward are formed to allow the shaft part of the engaging pin 34 to be engaged with an edge of a deep bottom part of each of the engaging pins 38 so as to correspond to movement of a position of the base end part of the chin resting material 24 in accordance with a plurality of predetermined elevation angles of a diagonal member 14. The engaging groove 38 is formed such that a sharp angle R1 made with a shaft line L1 along a front edge of the guide groove 36 and a contour line L2 of an upper edge of the engaging groove 38 is formed smaller than a sharp angle R2 made with the shaft line L1 along the front edge of the guide groove 36 and a contour line L3 of a lower edge of the engaging groove 38.SELECTED DRAWING: Figure 2
