    Abstract: A securing device for securing a door panel and a complementary door frame housing a latch means in a closed configuration against forced entry. The securing device includes receiving means mounted on the length of the door frame and an engaging means mounted on the length of the door panel, wherein a portion of the engaging means is pivotable between a first configuration and a second configuration. In the second configuration the portion of the pivotable engaging means is nested within the receiving means thereby preventing the door from being forced open. The engaging means is moved between the first and second configurations by a latch engaging means which interconnects the pivotable portion of the engaging means with the latch.

    Abstract: The invention is concerned with a lock mechanism of the kind having a deadbolt (9) which is operable by either an inside actuator or an outside actuator. The inside actuator usually includes a turn knob or the like, and the outside actuator usually includes a key operated lock. The lock mechanism includes a gear train (8) through which each of the two actuators is drivably connected to the deadbolt (9). The gear train includes two drive gears (13, 14) which are independently rotatable about a common axis of rotation, and each is connected to a respective one of the two actuators so as to rotate in response to operation of that actuator. The gear train (8) also includes two driven gear (17, 18) which are united to form a single piece composite gear (16), and each driven gear (17, 18) is cooperable with a respective one of the two drive gears (13, 14). The composite gear (16) is connected to the deadbolt (9) so that the deadbolt (9) moves between operative and inoperative positions in response to rotation of the composite gear (16). Each actuator adopts a rest position when the deadbolt (9) is in the inoperative position, and neither drive gear (13, 14) cooperatively engages with the composite gear (16) when the respective actuator is in the rest position. Furthermore, the gear arrangement is such that the outside actuator turns through 360° to cause the deadbolt (9) to move from one of its positions to the other, whereas 180° rotation of the inside actuator is sufficient to effect the same degree of deadbolt movement

    Abstract translation: 本发明涉及具有可由内部致动器或外部致动器操作的锁死杆（9）的锁定机构。 内部致动器通常包括转动旋钮等，外部致动器通常包括钥匙操作的锁。 锁定机构包括齿轮系（8），两个致动器中的每个致动器可驱动地连接到锁死杆（9）。 齿轮系包括两个驱动齿轮（13,14），它们可以围绕共同的旋转轴线独立地旋转，并且每个驱动齿轮连接到两个致动器中的相应一个致动器，以便响应于该致动器的操作而旋转。 齿轮系（8）还包括两个从动齿轮（17,18），两个从动齿轮（17,18）联合形成单件复合齿轮（16），每个从动齿轮（17,18）可与两个驱动齿轮 （13,14）。 复合齿轮（16）连接到锁舌（9），使得锁舌（9）响应于复合齿轮（16）的旋转在操作位置和不工作位置之间移动。 当致动器处于非工作位置时，每个致动器采用静止位置，当相应致动器处于静止位置时，驱动齿轮（13,14）都不与复合齿轮（16）配合接合。 此外，齿轮装置使得外部致动器转过360°以使得止死螺栓（9）从其一个位置移动到另一个位置，而内部致动器的180°旋转足以实现相同程度的锁死 运动

    Abstract: An improved latch guarded door lock and frame system is provided. A recessed surface is provided in a hollow metal frame, and is dimensioned to accommodate a latch guard so that the external surfaces of the door, frame and latch guard are flush. The recessed surface of the frame behind the latch guard is further reinforced by employing a thicker wall than is used in the rest of the frame, and by welding a square metal tube into the recessed region. A medial metal support is also welded into the lock box cavity in order to prevent the lock box from collapsing under stress. The resulting door lock and frame system is less penetrable than prior systems, and provides greater security because the latch guard is less vulnerable to prying and because the frame and lock box are reinforced, thus less likely to collapse under stress.

    Abstract translation: 提供了一种改进的锁紧门锁和框架系统。 凹形表面设置在中空金属框架中，并且其尺寸设计成容纳闩锁防护件，使得门，框架和闩锁保护罩的外表面是齐平的。 通过使用比在框架的其余部分中使用的壁厚更厚的壁，并且通过将方形金属管焊接到凹陷区域中，框架后面的框架的凹陷表面被进一步加强。 内侧金属支架也焊接在锁箱内，以防止锁箱在应力下塌陷。 所产生的门锁和框架系统比以前的系统更不易穿透，并且由于闩锁防护装置较不易于撬动并且因为框架和锁箱被加强，因此在应力下不太可能崩溃，因此提供更大的安全性。
