Embodiment Construction

[0049] Hereinafter, embodiments of the present invention will be described according to the reference numerals in the drawings, but the present invention is not limited to the following embodiments. In the present invention, the term "the front end of the stretcher" means that when the stretcher is loaded on the ambulance, the front end will be close to the side of the ambulance. That is, the side on which the fixed caster is attached is called a front end part. Therefore, when the stretcher is unloaded from the ambulance and transported, the rear legs with rotatable casters are transported in the forward direction. In addition, the head side of the stretcher means the same side as the front end portion of the stretcher trolley, and the foot side of the stretcher means the side corresponding to the rear end portion of the stretcher trolley.

[0050] The stretcher trolley 100 of the present invention is as figure 1 As shown, there is a rectangular frame-shaped upper frame 11...

Abstract

A highly safe stretcher that can be moved up and down smoother and where a stopper mechanism is more reliable, so that the stretcher can be correctly handled by ambulance crews. A stretcher (100) has casters on front legs (15) and rear legs (17), an upper frame (11) on the upper part of which a stretcher body is placed, constant load springs (28, 29) in a slide mechanism for vertically varying the position of the upper frame (11), and mechanical lock mechanisms (32, 33) for stopping the upper frame at desired positions. The stretcher (100) further has a lock mechanism (31) for locking front leg-assisting frames (16), for supporting the front legs, so as not to slide, and has rear leg-assisting frames (18) for supporting the front legs (15), the front leg-assisting frames (16), and the rear legs (17). The stretcher (100) is characterized in that rollers (36) are provided between supporting portions of the lock mechanism (31) and of the rear leg-assisting frames (18) and a center rail (14). The rollers (36) smoothen the slide motion between the supporting portions and the center rail (14).

Description

technical field [0001] The invention relates to a stretcher trolley for transporting emergency patients and patients, and relates to a stretcher trolley and a stretcher loaded on the stretcher trolley. The stretcher trolley can quickly and stably place emergency patients and the stretchers on which the patients ride on the stretcher trolley, and firmly fix the stretchers. Background technique [0002] The stretcher cart loaded by the ambulance used to transport emergency patients can be loaded in the ambulance after the front and rear legs are folded. In particular, since it is an emergency device, its structure requires that its legs be folded so that it can be easily loaded into an ambulance and lifted off from the ambulance. Moreover, because it is used to transport critically ill patients or emergency patients, its structure requires that when the stretcher is loaded into the ambulance, the structure for folding the legs of the stretcher should be able to move smoothly ...
