Windbreak device for balance

Abstract

A roll-top shield for weighing scales including a stationary hood 11 and a rotatable hood 12, both being made of a transparent material. Right and left side walls of the rotatable hood 12 are rotatably secured to right and left side wall of the stationary hood 11, respectively by means of pins 13a and 13b, respectively extending in the horizontal direction. By rotating the rotatable hood 12 over the stationary hood 11, an opening having a large size can be obtained, and a large or elongated article can be easily put on and off a weighing dish of a weighing device through the opening. When the rotatable hood is stopped at any desired position between a closed position and an open position without holding by hand, the opening having a desired size can be obtained, while both hands of a user are free.

Description

Technical field [0001] The present invention relates to a wind-proof device installed on an electronic scale or the like to block external air when accurately weighing items. Background technique [0002] In electronic scales that require precise weighing, in order to avoid the influence of wind pressure and turbulent airflow on the measurement accuracy, it is sometimes necessary to shield the outside air to some extent and enclose the object to be measured with a windshield. Less. [0003] In the past, various solutions have been proposed for the windshield of the scale. Generally, various technical solutions of box shape, vertical cylindrical shape, spherical shape and hemispherical shape have been well known. Among them, in the case of a box-shaped windshield, the opening is usually composed of two left and right sliding doors installed in the front, and the opening is opened by pulling one of the left and right sliding doors in the horizontal direction, which can carry items ...

AI Technical Summary

Problems solved by technology

[0004] However, in the case of a box-shaped windshield, since the area of ​​the opening of the object to be weighed is limited, even if it is the largest, it is only the size of one of the two sliding doors, so especially when the weighing volume is large or long. When the object to be measured is of a large size, it is often impossible for the object to enter and exit through the opening

[0005] In addition, in the case of vertical cylindrical and spherical windshields, it is difficult to secure a sufficient volume inside the windshield, and sometimes it is impossible to weigh large or long objects to be weighed.
