Title: Комплексна защитна система за подвижни работни площадки
Inventor: TSANKOV IVAN
IPC: F15B21/02
Filed: 2016-06-22
Abstract: Комплексната защитна система предотвратява опитите за ремонт от неоторизирани лица и неправилната експлоатация на подвижните работни площадки. Системата се състои от три подсистеми, управлявани от програмируем логически контролер (6). Първата подсистема следи за транспортното състояние на площадката чрез крайни изключватели (4), а чрез сензори за близост (3) - на стабилизатори. Втората подсистема забранява придвижването на шаси при работно състояние на машината, отчитано чрез задействане на някое от релетата за налягане (1) и/или някой от крайните изключватели (4), водещо до включване на електропневматичен клапан (11), задействащ спирачките на шасито и предотвратяващ движението му. Третата подсистема разрешава/забранява работата със стабилизаторите/рамената на работната площадка. При индикирано транспортно състояние на площадката, работният флуид се пренасочва към стабилизаторите посредством електрохидравличен разпределител (13). Стабилизацията е успешна, когато релетата за налягане (1) са задействани и сензор за наклон (10) индикира наклон на шасито до 10 градуса в двете оси, след което електрохидравличният разпределител (13) пренасочва работния флуид към площадката. В случай на аварийна ситуация, стоп бутони задействат електрохидравличния разпределител (12), прекъсващ главна хидравлична магистрала. 1 претенция, 1 фигура

IPC: A47C20/04
Filed: 2002-07-22
Abstract: A reclining element includes a pivotal backrest, a headrest, which is coupled in an articulated manner thereto, and optionally a footrest. These pivotal parts can be displaced by an electromotive adjusting device. The reclining element is so configured as to eliminate the need for the link lever fastened to the pivot shaft, whereby the forces required for adjusting can be transmitted by an appropriate kinematic system to the footrest or backrest. In order to raise the backrest, an articulated lever ( 20 ) is used, which is provided in the form of a toggle lever and which is connected to the adjusting element. A lever ( 20 a) of the articulated lever ( 20 ) is coupled to the adjusting element ( 18 ). The other lever ( 20 b) is coupled to the backrest ( 11 ) so that when the adjusting element travels out of the end position, the joint ( 21 ) executes a guided linear movement and a rotational movement that leads to a blocking of the articulated lever ( 20 ) in a particular blocking position. A preferred embodiment of the reclining element is a slatted frame.
