Description

The invention relates to an individual attachment point for attachment to a climbing protection rail of a vertical ladder. The mobile attachment point has a bracket on which at least one fastening device and a stop lug are provided.

In order to prevent a user from falling off a ladder, a pedestal or the like, climbing protection systems are used. Permanently installed climbing protection systems typically consist of a guide rail, which is mounted on a ladder, and a safety gear, which is guided in the guide rail. The person to be secured carries a safety harness and is connected via a connecting means with the safety gear. The connecting means is attached to a stop point of the safety gear. In the event of a crash of the user, the safety gear is locked by a locking device on the guide rail and thus prevents the user from crashing.

In addition to these "follower" climbing protection systems, in which the attachment point is always moved along with the user via the catching device movable in the guide rail, it is sometimes necessary to attach temporary, fixed attachment points to a fall arrest system. Conventionally, an attachment of fixed attachment points is possible only by comparatively complicated screw fasteners.

A frequent displacement of fixed attachment points is uneconomical when the attachment and detachment of these attachment points requires the time-consuming use of appropriate tools. In such cases, there is a need for fixed attachment points that can be attached to an existing fall arrest system in a short amount of time.

The object of the present invention is therefore to provide a single point of attachment which can be mounted on an existing fall arrest system in a time-saving and effective manner.

According to the invention this object is achieved in a single point of attachment of the type mentioned by a device having the features of claim 1 of the present invention.

The single attachment point for attachment to a climbing protection rail of a vertical ladder has a bracket on which at least one fastening device and a stop lug are provided. The bracket has a first end, with which it can be suspended in a recess of the climbing protection rail.

The single point of attachment of the present invention offers the advantage that it can be attached without tools to an existing climbing protection device and also released again. The insertion and removal of the single attachment point of the present invention can thus be time-saving and effective.

In a preferred embodiment, the bracket of the single attachment point at its first end to a T-shaped projection which is angled at 90 ° relative to the bracket. The crossbar of the T-shaped projection of the bracket is dimensioned so that it can be inserted into the recess of the fall arrest rail, preferably a slot. The longitudinal beam of the T-shaped projection is dimensioned so that the inserted bracket is anchored by a rotation of 90 ° in the recess of the climbing protection rail.

The special anchoring by a rotation of the bracket by 90 ° increases the safety of the single attachment point. A release of the single stop point is possible only by a targeted opposite rotation of the bracket, so that an unintentional removal of the attachment point is almost impossible.

To increase the stability of the individual attachment point, the bracket is preferably shaped such that its second end rests on a rung of the vertical ladder when the first end of the bracket is suspended in the recess. Preferably, the second end of the bracket relative to the bracket is angled at 90 °.

Preferably, the second end of the bracket on a device with which it is secured against lateral slippage against the fall arrester rail. For example, the second end of the mounting bracket may have two fork-like arranged prongs, between which the fall arrester rail is located and thus prevent lateral slippage of the single attachment point.

Preferably, the single stop point, when the T-shaped portion of the bracket is inserted in the recess of the fall arrest rail, displaceable in the vertical direction. The second end of the mounting bracket is preferably angled stepwise, wherein the step surface of the second end rests on a rung of the uprights. The two fork-shaped prongs are also angled 90 ° relative to the step surface, so that the two prongs on the second end of the bracket include the fall arrest rail on both sides and engage behind a rung of the riser, so that a lateral slipping, as well as a forward tilting of the individual attachment point is prevented. The single stop point is in the recess of The climbing protection rail can be moved vertically in the vertical direction so that the two tines can be pushed behind a rung of the vertical ladder.

In a further preferred embodiment, the attachment eye of the single attachment point is rotatably mounted on the bracket.

The mobile attachment point is inserted with its first end, which has a T-profile, in a recess of a climbing protection rail and fixed by a rotational movement by preferably 90 ° to the climbing protection rail. To lock the second end of the single attachment point, which has two spaced-apart tines, trapped behind a rung of the climbing protection ladder.

The apparatus of the present invention will be explained in more detail with reference to the following figures. Show it:

1 Single point of attachment before attachment to the back of a fall protection rail;

2 Einzelanschlagpunkt whose T-shaped end is inserted into a rectangular slot of the fall arrester rail;

3 Rotation of the single stop point;

4 The single stop point is rotated by 90 ° and pushed to the upper end of the slot in the fall arrester rail;

5 The single stop point in the locked position seen from the back of the climbing ladder;

6 The single point of attack in the locked position seen from the front of the climbing ladder.

In 1 is a preferred embodiment of a single point of attachment 10 displayed. The single stop point 10 becomes without the use of tools on a fall protection rail 12 of the climbing protection system 14 attached. The climbing protection rail has recesses 16 , preferably oblong holes, in which the single attachment point 10 can be used. The single stop point 10 can z. B. be used together with the Söll GlideLoc ^® climbing protection system.

The single stop point 10 consists of a hanger 18 , which is angled at 90 ° at its first end (here: left end) and a T-shaped profile 20 having. The length and width of the crossbeam 22 of the T-shaped profile 20 is chosen so that this in a rectangular slot 16 in the climbing protection rail 12 of the climbing protection system 14 can be used. The second end (here: right end) of the temple 18 is stepped angled. A step surface 24 is opposite the temple 18 Angled at 90 °. From the step surface 24 extend two spaced prongs 26 , in turn, at an angle of 90 ° with respect to the step surface 24 are angled. The distance of the tines 26 is slightly larger than the width of the fall arrester rail 12 , On the temple 18 is a lifting eye 28 rotatably mounted. A person to be secured, wearing a safety harness can, via a connecting means with the stop lug 28 of the single stop point 10 get connected.

In the other figures is shown as the single point of attack 10 on the climbing protection rail 12 is attached. As in 2 is shown, the single stop point 10 first with the first end of the stirrup 18 on which the T-profile 20 located in a rectangular slot 16 the climbing protection rail 12 introduced. Subsequently, the hanger 18 turned 90 ° downwards so that the longitudinal axis of the mobile attachment point 10 parallel to the climbing protection rail 12 is oriented (see 3 and 4 ). As in 4 pictured, the hanger becomes 18 as far as possible pushed upwards, so that the longitudinal beam 30 of the T-profile 20 the upper end of the slot 16 the climbing protection rail 12 touched. In this position are the tines 26 just above a rung 32 the climbing ladder 34 , In this position, the bracket can 18 over the rung 32 the climbing ladder 34 be pivoted. After pivoting lies the lower contact surface 36 of the temple 18 at the back of the climbing protection rail 12 as the forks turn 26 on the opposite sides of the climbing protection rail 12 are located. Finally, the hanger 18 as in the 5 and 6 shown, pushed down, with the tines 26 then behind the rung 32 the climbing ladder 34 issue. The step surface 24 the second end of the temple 18 lies on the rung 32 and contributes to further stabilization of the single point of impact 10 at. As soon as the single stop point 10 in the final position, as in the 5 and 6 can be used for backup by a user.

To release the single stop point 10 this must only be raised so far that the tines 26 over the rung 32 can be swiveled forward again. Subsequently, the hanger 18 turned back 90 ° and the first end of the bracket 18 with the T-profile 20 out of the slot 16 the climbing protection rail 12 away. Because removing the single stop point 10 always lifting the strap 18 Required is an accidental removal of the single stop point 10 almost impossible. In particular, the individual attachment point can 10 do not solve in case of a fall of the person to be secured, as in a fall only a downward traction on the single stop point 10 acts.
