    Abstract: A safety structure for a cover device includes a base assembly and a cover assembly. The base assembly has a concave portion. The cover assembly is hinged to the base assembly and may cover the base assembly. The cover assembly has a cover body and a projection, which may elastically protrude out of and retract into the cover body, and may be fit into the concave portion for positioning. The projection is configured such that it may retract into the cover body to prevent an object from being hurt when the cover assembly is placed down and touches the object.

    Abstract: A track has walls which enclose a hollow interior and among these walls are two laterally directed flanges which are separated by a slot that opens downwardly out of the track for the full length of the track. The track contains trolleys having wheels which roll along flanges of the track and the trolleys carry hangers which depend through the slot in the track and are attached to a door or some other suspended device. One of the trolleys also carries a latching mechanism which engages a keeper located within the track to secure the trolleys and suspended device in a predetermined position along the track. The latching mechanism includes a latch bar which pivots on the trolley between engage and release position and a spring which urges the bar to its engage position--the position in which it will engage the keeper upon encountering the keeper. The latching mechanism also includes a release cord which depends from its latch bar through the slot in the track and, when pulled, causes the latch bar to pivot against the bias of the spring.

    Abstract translation: 轨道具有封闭中空内部的壁，并且在这些壁之中是两个横向定向的凸缘，其由在轨道的整个长度上向下向外打开的槽分隔开。 该轨道包含具有沿着轨道的凸缘滚动的轮子的手推车，并且手推车携带悬挂器，其依赖于轨道中的狭槽并且附接到门或一些其它悬挂装置。 手推车中的一个还具有闭锁机构，其接合位于轨道内的保持器，以将手推车和悬挂装置沿着轨道固定在预定位置。 闩锁机构包括在接合和释放位置之间在推车上枢转的闩锁杆和将杆推到其接合位置的弹簧 - 在遇到保持器时它将与保持器接合的位置。 闩锁机构还包括释放绳索，该释放绳索从其闩锁杆通过轨道中的狭槽，并且当被拉动时，使得闩锁克服弹簧的偏压枢转。

    Abstract: A drive mechanism comprises a support upon which a drive member is mounted for movement relative to a frame. The drive member comprises first and second elements which are relatively movable, the one of which may be mounted on the other. The elements are interconnected by a resilient member which transmits the drive therethrough, a drive input being coupled to a one element, a drive output to the other element. A detector generates a signal output responsive to relative movement of the elements which may serve to control a drive transmitted through the mechanism. In a preferred embodiment, the support is a rotatable screwed shaft and the first element a traveller thereon upon which the second element is slidably mounted, the elements being interconnected by helical springs.

    Abstract: An electromagnetic door holding device for a door closer of the type having a spring operated rotating spindle operatively connected by an arm to a slider mounted for reciprocal movement in a track usually secured to the door frame wherein the slider has a cam which when the door is swung to a fully opened position engages and is held by an electromagnet against movement relative to the slider when the door attempts to return to a closed position and which engages and moves a detent carried by the slider into engagement with detent engaging means in the track so as to prevent movement of the slider relative to the track and thus releaseably hold the door in the open position. The energizing of the electromagnet allows the spring to move the cam out of engagement with the detent and thus permit the slider to move and enable the door to move to a closed position.
