AI Technical Summary
Technical Problem
Existing alarm devices for preventing falls from high-altitude work platforms are inadequate, as they may not detect foot extension beyond the edge reliably, can be damaged by operator weight, and are ineffective in noisy environments.
Method used
An alarm device with a foot-receiving member and a switch that detects when an audible and tactile alarm is triggered by foot extension, using a resilient elastic buffer to prevent damage from operator weight, and is designed for easy retrofitting to workbenches.
Benefits of technology
The device effectively prevents falls by detecting foot extension and triggering an alarm, reducing damage risk and ensuring alert perception in noisy conditions.

Abstract
The present invention provides an alarm device to prevent workers from falling from the work platform. [Solution] The work platform includes a fixed part (10a) provided at the end of the work platform, a switch device (12) housed in the fixed part, a foot rest member (11) positioned on the fixed part, and an alarm device (13) that emits an alarm signal when the switch device is switched from an OFF state to an ON state. The device is configured to be switched ON when the foot rest member (11) is subjected to a load and moves downward, and the switch device is pressed downward when the ON state is activated. The casing (35) of the switch device is supported by an elastic buffer (38) that is compressible and resilient. The device is configured to allow the switch device (12) to move downward when the foot rest member (11) is subjected to a load and moves downward, by compressing the elastic buffer.
