Extension ladder

The innovation concerns είπε plug-in ladder, consisting made up of several snap-together single-spar plug-in links with risers arranged on both sides « Support and holding elements and '

Single-stem extension ladders of the type mentioned are general known. Such8 ladders are used, for example. to the Climbing wooden and concrete poles, bouie to climb tall trees. They are also used to repair or to repair electrical equipment Forstsrbsitsn sn BsurREn to carry out, bspüi. to the Limbing or for harvesting seeds.

When using such ladders in the areas of application mentioned, it is necessary to that the user is secured accordingly. So far this has been done by the user putting on a waist belt, the nine additional Has loop around the mast to be climbed bztj. Tree trunk is laid.

When climbing up or down, this loop has to be constantly moved, especially with tree trunks can be cumbersome because of the protruding Astan • ets or the like. Unevenness the loop cannot easily slip or be retightened. To remedy this is the task of the present Uen Innovation, i.e. a plug-in ladder should be created, or a plug-in ladder should be created at the beginning mentioned type to the effect that the security element for the user immediately Part of the ladder itself and that the security loop does not have to be pushed or tightened - Difficulty when using such a

liolm ladder represents more.

This task is with a ladder of the opening named type according to the innovation by the in the license plate of the main claim covered solved. Further training variants result from the sub-claims.

This innovative training makes the fall arrester, to which the safety belt is attached, for example by means of a detachable eyelet connection, directly even led to the ladder and can be due to

the formation of the plug-in links unhindered go through top and bottom, i.e. the user himself only has one safety connection to the ladder, uaa-but is absolutely harmless because the Whole EinhDlm extension ladder with its individual links in the known easy-going manner on the mast to be climbed or tree trunk is fixed and secured sufficiently by the support and holding elements.

The new single-stem extension ladder and its execution farms are described in more detail below with the aid of the graphic representation of exemplary embodiments explained.

The single-stile extension ladder is seen from the side according to Fig. 1, wherein the lower plug-in link, tiiie recognizable, is angled to the mast base, lüurzelstammausläufer or the like. To be able to bridge.

For the stalks 1 of the individual plug-in links 2 can According to FIGS. 2 to 6, the most varied of profiles are used, only being essential; that a guide rail 2 'or a guide channel 2 "with short retaining legs 5 results, on which the fall arrester 6 (Fig. 8) is attached, guided and can be held.

It is essential that the fall arrester 6 the respective connector area of two adjacent connectors 2 can pass unhindered.

According to Fig. *, 9 each plug link 2 is provided at the end 9 ¹ with a sufficiently long crossbar 12 and the other end with a correspondingly long plug pin 11 which is welded to the base web la of the U-profile or attached in a suitable manner.

The same applies to the profile according to FIG. 5, however represents a double profile, since the Crossbar 12 extends over the entire length of the plug-in link.

For example, according to FIG. 6, lo are the Plug-in connection elements to the outside and zuar in the form of sines attached to the outside of the base bridge la Socket pin 11 and sines sufficiently long StEckbügel 13 at the other end.

It is essential in all embodiments that the connecting element B 7, B (bzu. 11,12) either inside or outside of the flow area of the fall protection sleeve 6 on the connector area 17 are arranged so that the fall arrester ß ^ on its retaining lock IS dsr seat belt (not shown) attached for the user, also about the plug connection areas 17 glsitsn bzu. rollsn and thus over the entire length of the length can be moved unhindered.

The plug members 2 are provided in a known hleise FIG. 1.7 with supporting and holding elements and that jetdeilB is attached with two brackets supports 13, on which a Umschlingungsgurt IU für.den stem 18, which are lashed by one end to a ratchet closure 15 can.
