摘要： A safety apparatus (1) comprises a left part (1) and a right part (20) which are mirror images of each other. The left part (1) comprises a frame (2) having an inner portion (10) with an upper hook (11) and a lower hook (12) for engaging a ladder in-between the ladder rungs. There is a cranked portion (13) in the frame (2), and an outer portion having an arm (15) and a brace (16) splayed out to the side. The arm 15 terminates in a ground-engaging foot (14). Thus, as viewed in plan, the left and right parts are splayed out as best viewed in Fig. 3. A tensioned elasticated rope support (3) has hooks (5, 6) at its ends, the hook (5) engaging the foot (14) and the foot (6) engaging a ladder L rung. An alternative frame (100) has an arm (104) extending at an angle to the plane of the inner end (101) and is bent downwardly so that its end forms a ground foot (105). This arrangement allows a single length of tube to form the inner portion S-shape, the bend for splaying out, the outer portion arm, and the ground-engaging foot. It is therefore of lightweight and high strength construction while being inexpensive to manufacture. The safety apparatus is very easily attached to a ladder. As the ladder 1 is being user there is excellent resistance to slipping and sliding of the ladder away from the wall because there are four ground- engaging feet. Also, there is much reduced risk of the ladder swaying to a side because of the fact that the parts 1 and 20 are splayed out.
摘要翻译：安全装置（1）包括彼此镜像的左侧部分（1）和右侧部分（20）。左侧部分（1）包括框架（2），该框架具有带有上钩（11）和下钩（12）的内部部分（10），用于接合阶梯之间的梯子。在框架（2）中具有曲柄部分（13），并且外部具有向侧面张开的臂（15）和支架（16）。臂15终止于地面接合脚（14）。因此，如在平面图中所看到的那样，左右部分如图3中最佳地看到的那样展开。张紧的松紧绳支撑件3在其端部具有钩子5，钩子5接合脚部（14）和脚（6）接合梯子L梯级。另一种框架（100）具有与内端（101）的平面成一定角度延伸的臂（104），并向下弯曲，使得其端部形成地脚（105）。这种布置允许单一长度的管形成内部S形，用于展开的弯曲部，外部部分臂和地面接合脚。因此它具有轻质和高强度的结构，同时制造成本低廉。安全装置很容易安装在梯子上。当梯子1正在使用时，由于有四个地面接合脚，所以梯子远离墙壁滑动和滑动的阻力非常好。此外，由于部件1和20张开的事实，梯子向侧面摇摆的风险大大降低。
