Transitional slope rack of doorsill

Abstract

A transitional slope rack of a doorsill is characterized in that the outer contour of a cross section of the slope rack has a trapezoidal structure; the top, the bottom and the height of the trapezoidal structure form a rectangular inner contour; the lower side of the rectangular inner contour is an opening; closed structures with triangular cross sections are respectively formed on two sides of the rectangular inner contour; the top of the trapezoidal structure is slightly greater than the width of the doorsill; the height of the trapezoidal structure is slightly greater than the height of the doorsill; the length of the slope rack is not greater than that of the doorsill; and the opening of the open rectangular inner contour downwards sleeves the doorsill. The transitional slope rack of the doorsill has the advantages that objects with rollers can climb over the doorsill quite stably and easily, and the doorsill cannot be extruded or damaged.

Description

[0001] This application is a divisional application, and the filing date of the parent case is April 17, 2012; the application number of the parent case is 201210112880.2; the invention name of the parent case is "Transition Ramp for Threshold". technical field [0002] The invention relates to a threshold transition ramp, which is used for assisting objects with rollers to cross the threshold when entering and exiting. Background technique [0003] In order to prevent foreign objects from entering, thresholds are set under many doors, which also serve as an auxiliary defense. However, in many cases, the threshold also has a certain hindering effect. In the production workshop, some trolleys with rollers often come in and out, but the door of the workshop is set up with a threshold higher than the ground. Stable, the article on the trolley is easy to drop; If want to make the car body pass smoothly, then need manpower to lift and pass, caused a lot of inconveniences thus. ...

AI Technical Summary

Problems solved by technology

The support plate is installed directly under the pedal, without forming a closed structure, and is in direct line contact with the ground. Due to the lack of a base plate, it is easy to crush the ground

In addition, the pedal is rigidly supported by the support plate, which makes the span bridge poor in elasticity, so that the passing trolley vibrates greatly, and the hand-feeling vibration of the trolley is also relatively large.

[0005] What CN202012035U pursues is foldability. If it is changed to a hollow closed structure, the foldability can no longer be realized, which will deviate from the purpose of its invention
