Abstract: An automatic closure mechanism, particularly adapted for use with a toilet seat is described. The mechanism will automatically lower a toilet seat that has been rotated to a raised position after a time interval determined by the viscosity of a damper fluid in a dashpot of the mechanism. The mechanism is simply constructed and preferably integral with a rear edge of the toilet seat so that it provides a clean, neat appearance which is aesthetically pleasing and does not interfere with cleaning or maintenance of the toilet fixture. The mechanism includes a dry coil spring section and a hydraulic dashpot section. The dashpot includes a primary flap valve and a relief flap valve which permit the toilet seat to be raised with very little resistance and automatically returned to a lowered position after about 1-5 minutes, depending on the viscosity of the damper fluid in the dashpot. The automatic closure may be overridden to forcibly return the seat to the lowered position in an emergency situation without damage to the seat or the closure mechanism. The advantages include a simple, economic construction, a neat appearance, and a robust closure mechanism which cannot be damaged by a manual override of the closure damper.

Abstract translation: 描述了一种特别适用于马桶座圈的自动关闭机构。 该机构将在由机构的缓冲器中的阻尼器流体的粘度确定的时间间隔之后自动降低已经旋转到升高位置的马桶座。 该机构简单地构造并且优选地与马桶座的后边缘成一体，使得其提供了在美学上令人愉快的干净整洁的外观，并且不干扰马桶固定装置的清洁或维护。 该机构包括干式螺旋弹簧部分和液压缓冲器部分。 缓冲器包括主瓣和释放瓣阀，其允许马桶座圈以非常小的阻力升高，并且在约1-5分钟后自动返回到降低位置，这取决于缓冲器中的阻尼器流体的粘度。 自动关闭可以被覆盖，以在紧急情况下将座椅强制地返回到降低的位置，而不会损坏座椅或关闭机构。 这些优点包括简单，经济的结构，整洁的外观和坚固的闭合机构，其不会被闭合阻尼器的手动超控而损坏。
