Definitions
- the invention relates to a ladder with at least two bars and rungs arranged between them.
- the object of the invention is to achieve a substantial improvement in the stability of conductors with a simple safety device.
- the invention with which this problem is solved is characterized in that a support rod is fastened on both sides in the upper region of a pair of spars via a joint, the support rods for lateral support of the ladder in their extended position being individually telescopically adjustable in length on the ground and determined in the desired pull-out position can be locked.
- This safety device can be used for fixed ladders as well as free-standing ladders.
- FigJ a fixed ladder with two support rods
- FIG. 2 shows a partial view of the fixed ladder according to FIG.
- the 1 and 2 is designed as a fixed ladder.
- the bars are connected to rungs 2 in the usual way.
- the two ladder parts of the fixed ladder are articulated with a pivot 3.
- One of the ladders is preferably provided with an extendable ladder 4 according to double arrow A.
- In the upper spar area there is a joint 5 on each side of the spars 1, of which one support rod 6 protrudes laterally. These support rods 6 are telescopically extendable and fixable in the desired pull-out position.
- the bars are infinitely lockable with a quick release.
- the respective pull-out position of the support rods 7 can be fixed in a manner known per se by mutual rotation of the rod parts, by clamping sleeves or the like. However, it is also possible to provide a step-by-step locking through the cross pins penetrating the two tube parts.
- the lower end of the rod is advantageously provided with tips 6, which are intended for penetration into the ground.
- the joint 5 is movable in several planes, for example in the manner of a cardan joint or as a ball joint, and is connected to the support rods 7.
- the support rods 7 can be spread apart to a large extent in relation to the conductor level and can be secured to the floor by the tips 6.
- the support rods 7 When not in use, the support rods 7 can be inserted into openings in a cross strut 9 at the lower end of the conductor by holding means.
- the support rods can be used with fixed ladders as well as with free-standing ladders, including extension ladders if necessary. Since the support rods are telescopically variable in length, the spreading position can be easily adapted to the respective terrain. In the case of inclined terrain, the pull-out position of the two support rods 7 can also be different.
- the conductors provided with the support rods 7 mentioned result in a substantially increased stability and thus reduced risk of accidents.
- the safety device could be designed differently within the scope of the invention.
- spring-loaded clamps or the like could be provided for the holding means for fastening the support rods.
