Title:
ROTARY DECK PROVIDED WITH IMPACT-REDUCING FRONT BLOCK UNIT OF EMERGENCY VEHICLE TURN APPARATUS FOR MEDIAN STRIP
Document Type and Number:
WIPO Patent Application WO/2021/206245
Kind Code:
A1
Abstract:
The present invention relates to a rotary deck provided with an impact-reducing front block unit, of an emergency vehicle turn apparatus for a median strip. The objective of the present invention is to provide a rotary deck provided with a front block unit, the rotary deck constituting an emergency vehicle turn apparatus installed along a section of a median strip, in which, in the case of an emergency, each of the angle decks constituting the rotary deck are rotated symmetrically to the left and right sides, enabling, through the upper surface thereof, an emergency turn of a vehicle, and in a normal situation, the front block unit located under the lower portion of the angle decks is allowed to bounce off while rotating at an angle corresponding to a collision incidence angle when a vehicle collides, and thus, the rotary deck can reduce structural deformation of the emergency vehicle turn apparatus and the scattering amount of broken components, and also can reduce the impact transmitted to passengers. The constitution of the present invention is characterized by the rotary deck provided with the impact-reducing front block unit, of an emergency vehicle turn apparatus for a median strip, the rotary deck constituting the emergency vehicle turn apparatus installed at each section of a road median strip (100), wherein the rotary deck (1), which is configured such that a pair of symmetrically installed angle decks (12) are rotated in the case of an emergency by each hydraulic cylinder so as to come into contact with a paved road surface on the left and right sides, comprises a front block unit (2), which is coupled under the lower portion of each angle deck (12) by a link unit (3) and has a structure that functions as a median strip in a normal situation where the rotary deck is not in operation, and reduces the impact when a vehicle collides.
