Title:
COUPLING DEVICE FOR SAFETY HANDRAIL OR SIMILAR MEMBER IN PARALLEL
Document Type and Number:
Japanese Patent JP3501413
Kind Code:
B2
Abstract:
PURPOSE: To attain miniaturization and lightening and the reduction of cost by instantaneously joining two members extended in the horizontal direction by fixing working, by which the separation of the two members is made impossible, when an impulse in an extent having working on the separation of the two members is applied to at least one of the two members.
CONSTITUTION: When powerful horizontal stress to the space of the two members 31, 32 of a handrail 3 is applied to either one of the two members 31, 32 in relation to others, a tendon 10 penetrated to a block 6 instantaneously has working in the direction of the arrow F and the direction of the extension 102 suddenly. Divided truncated wedges 15 surrounding the tendon 10 in a truncated boring 14 are moved in the direction of a block 5, and the wedges 15 fix the tendon 10 onto the block 6 at that time. The tendon 10 is unified with the block 6, finally the handrail 3. Accordingly, the mutual spatial changes of the two members 31, 32 of the handrail 3 are made impossible.
