Problems solved by technology

[0002] The sad fact is that the number of accidents related to the use of ladders remains too high, resulting in serious injuries and in some cases fatal injuries
In most if not all cases, the cause of such accidents is that the ladder is not stable enough when leaning against a wall or similar structure

Embodiment Construction

[0031] exist figure 1 In , the ladder 10 is seen to be supported on the pit 16 or the like against the pit wall 20 . At the upper end of said wall 20 there is a floor edge 22 which rests on the adjacent floor surface 18 . The ladder 10 comprises two long handrails 12 in an upright - almost upright orientation in said support position. There are steps 14 on which someone can stand between the handrails 12 . The support brackets are not shown in this figure.

[0032] figure 2 The inventive ladder support bracket of the left hand handrail 12 mounted between two rungs 14 is shown. The support frame comprises a support shoulder 24 with a support surface 30 by means of which the ladder rests on the floor surface 18 securely fixed sideways. This is because the floor edge has grooves in the horizontal floor surface, and the supporting edge surface 32 of the bracket can be placed in the grooves to improve said fixation. In doing so, the ladder is also secured against tipping bac...

Abstract

A ladder support bracket has a support shoulder for creating a support contact with a complementary backup. The bracket includes at least one jaw for joining the bracket to an upstanding rail of a ladder, the jaw having also a retainer mechanism by means of which the bracket - when being attached to a rail of a ladder - can be brought into a clamping position attaching the bracket unmovably to the rail and a release position holding the bracket in a swivel connection relative to the rail and / or movably along at least a section of such rail.

Description

technical field [0001] The present invention relates to a ladder and more particularly to a safety device which can be safely positioned against an object such as a pit wall when propped up eg in an elevator shaft. Background technique [0002] It is an unfortunate fact that the number of accidents related to the use of ladders remains too high, resulting in serious injuries and in some cases fatal injuries. In most if not all cases, the cause of such accidents is that the ladder is not stable enough when leaning against a wall or similar structure. A number of different arrangements have been proposed for stabilizing the ladder in its position of use. For example, additional brackets at the rungs of ladders have been proposed to allow additional contact with the ground for added stability, and struts for contact with supporting walls have also been proposed. [0003] For this reason, the safety requirements for entering elevator shafts have been strengthened, which can be...
