Embodiment Construction

[0011] The ice rescue ladder provided by the present invention includes a flexible contact surface 3, a hard support surface 2, a pedal 1 and a movable hinge, wherein the hard support surface 2 has two groups, which are rectangular parallelepiped plates made of wood or plastic to support and expand the force bearing area; the flexible contact surface 3 is fixed on the bottom of the hard support surface 2 and is made of rubber or foam; there are multiple pedals 1, made of wood or plastic, fixed on the hard support surface 2, It is used for rescuers to stand and move; the ice rescue ladder has multiple sections, which are connected by movable hinges. The specific connection form of the living hinge connection is common sense, and will not be repeated here. When the present invention is used, the ice rescue ladder is erected on the ice surface, the flexible contact surface 3 is in contact with the ice surface, and rescuers can implement rescue by stepping on the pedal 1 .

Abstract

The invention discloses an ice rescue ladder, comprising a flexible interface, a plurality of hard supporting surfaces, a plurality of pedals and an active hinge; wherein, two group of hard supporting surfaces are cuboid sheets made of timber or plastic, supporting and widening force area; the flexible interface is fixed at the bottom of the hard supporting surface and is made of rubber or foam; a plurality of pedals made of timber or plastic are fixed on the hard supporting surface for rescuers standing or moving; the ice rescue ladder is multistage; the stages are flexibly hinged. The ice rescue ladder has the advantages that the ladder has simple structure and can enlarge the force area to the largest extent, avoiding ice breakage; since the ladder has considerable hardness and bearing capacity, rescuers will be safe and convenient to carry out rescue on the pedals; the rescue ladder greatly improving life-saving efficiency is suitable for ice rescue.

Description

technical field [0001] The invention relates to a life-saving ladder, especially a life-saving ladder used on ice. Background technique [0002] In the cold winter, rivers, lakes, ponds and other places will freeze. Every year there are deaths caused by falling into ice caves. Even if it is discovered in time and rescue is taken, it is very dangerous because of the lack of effective life-saving equipment. [0003] In the "air bridge" patent (application number: 200620058830.0) disclosed in Chinese Patent No. CN2905887, the bridge body is composed of an inner layer of mesh cloth forming a closed inner cavity and an outer layer of mesh cloth adhered to the outside of the inner layer. The body is provided with an air valve communicating with the inner cavity. The disadvantages of this patent are: the ice surface has a certain hardness and bearing capacity, and this patent is relatively soft as a whole, and people standing on it cannot effectively expand the force-bearing are...
