Description

The present education is in the field of scaffolding and relates to a Steighilfesatz.

When working over the ground, ladders or scaffolding are used today. Ladders are regularly used by home improvement and small businesses. The ladders have the advantage of being easy to transport and set up. Scaffolding, however, are relatively expensive in the assembly. Scaffolding is regularly erected by corresponding specialist companies. In addition, it requires additional backups of the scaffold against falling.

The present invention is based on the problem of providing a device that facilitates working on the ground, which is easy to set up and also offers the greatest possible degree of adaptability to the practical requirements.

To solve this problem, with the present invention, a riser set comprising two joint conductors each having at least two conductor sections having rungs, and a joint arranged therebetween, and a bottom which can be fastened between the two joint conductors in an upright orientation thereof to form a framework.

The climbing attachment according to the invention has two known articular conductors. These have two conductor sections, each with two parallel extending spars and arranged therebetween, extending in the horizontal rungs. Between these two conductor sections a joint is provided. Accordingly, the articulated conductor of the conductor section can be extended to a relatively long conductor by pivoting the joint so that the two conductor sections are aligned in extension to one another. The ladder can be used for this purpose. It is also possible to form a ladder by pivoting the respective ladder sections, which stands without leaning against another object and carries a craftsman. By further pivoting of the conductor sections to each other they can be placed against each other, so that generates a relatively compact conductor with half the height of the swung ladder becomes. Sometimes such a ladder is necessary in order to work in confined spaces above the ground. The compact arrangement of the ladder sections also allows a space-saving storage of Steighilfesatzes.

The climbing attachment according to the invention comprises two of the articulated conductors described above. These articular conductors preferably have only one joint. It is also conceivable to use three or four articular conductors. However, the articulated conductor is preferred with a single joint and two equally long conductor sections.

The two articulating ladders of the climbing attachment can be set up in vertical orientation, parallel to each other in the vertical direction to form a scaffold. The individual articular conductors can in this case in the pivoted position of the conductor sections, i. be provided with maximum length, or with mutually parallel conductor sections. The climbing attachment has a bottom which extends in such an orientation of the mutual articular conductors between them and can couple them together to form a framework comprising the at least two joint conductors and the framework floor. This scaffold floor is in each case at the end on the rungs of the same height of the two articular conductors. This makes it possible to train the climbing attachment as a scaffold.

According to a preferred embodiment, which allows the creation of a scaffold, which can be erected cantilevered, the climbing attachment comprises transverse and diagonal struts, which can be attached to the mutual articular conductors. For this purpose, the sprouts of the joint conductors in a known per se inside hollow, for example, formed by a hollow rectangular or a hollow square profile. Through these hollow sprouts extend threaded rods that extend beyond the ladders in the longitudinal extent of the rungs on both sides. Nuts, preferably nuts that can be screwed by hand, such as wing nuts or thumbscrews, can be screwed onto the threaded studs of the threaded rods projecting above the ladders. These screws rest with the interposition of the attachment ends of the transverse and diagonal struts on the ladder and fix so these struts on the ladders. The diagonal braces prevent displacement of the parallel extending ladder in the manner of a parallelogram. The cross struts are on identical height of the ladder and thus ensure the position of the ladders to each other in the vertical.

The Steighilfesatz should have at two different levels cross struts, preferably in each case on both outer sides of the ladders. In a corresponding manner, a plurality of diagonal struts should be provided, preferably provided in the manner of a cross diagonal struts. This cross is preferably formed by diagonal struts which are struck on opposite sides on the ladders. The transverse or diagonal struts are preferably formed from hollow round profiles, which are each flattened end and provided with a bore for passing the threaded rod.

As a threaded rod every elongated structure is understood, which can be passed through the respective rungs and project beyond the rungs in the longitudinal direction each end. The thread does not have to be provided over the entire length of the threaded rod. A threaded rod in the sense of the present invention is also an elongated profile which has a threaded portion only at its end sides. This can be cut directly on the pole.

Preferably, the threaded rods are designed such that the attachment points can be mounted on at least one of the transverse struts and at least on one of the diagonal struts on the same threaded rod on the associated joint conductor. As a result, the possibility is created to mount a cross member at that point end to the ladder on which the end of a diagonal strut is fixed to the ladder. The development allows a relatively compact construction of the framework.

The climbing attachment according to the invention has, for example, a joint guide with seven rungs on each side of the joint. Such a joint conductor is referred to as 2 x 7 joint conductor. With such an articulated ladder a framework with a total height of about 4 m can be created. The ground is here regularly for safety reasons about 3 m above the ground; the overlying longitudinal portion of the respective articular conductors is used for the attachment of railing struts, which serve to secure a person standing on the ground. To increase the stability of such a scaffold formed by the two articular conductors is according to a further preferred embodiment proposed a support of the present invention, which projects beyond the framework in its transverse and longitudinal extent on the outside and having a widened foot. The foot is preferably articulated to the spar forming the post, preferably with the interposition of a length compensating means, for example a thread screwed into the post, which can be countered on the post. Via the supports, the upright framework can be additionally supported at points that are regularly outside the support points of the articular fibers. The bases of the articular conductors are usually formed by the spars on the outside by superior widened feet. These feet are located within a rectangular area, which are formed by the usually provided on each individual spar, outwardly projecting obliquely downwards in the longitudinal and transverse directions supports.

In order to provide the scaffolding with the best support possible, they are attached to the articulated ladder at a point usually 1 to 1 1/2 meters above the ground. For further stiffening and alignment of the supports is proposed according to a preferred embodiment of the present invention to provide spacer struts, each extending between a spar and the support and are fixed to these two parts. The spacer strut preferably extends beneath the third rung of the articulated conductor from the latter in the direction of the support. The spacer strut preferably extends in the horizontal at aufgeselltem scaffold.

The support and / or the spacer strut are releasably connected to the respective articular conductors in view of variable use of the two articular conductors of the riser assembly. For this purpose, according to a preferred embodiment of the invention, a clamp embracing the stile of the articulated conductor is proposed which has a fastening eye protruding from the stile for fastening the stanchion or the spacer strut. The clamp preferably has a U-segment encompassing the stile and projecting beyond it, and a clamping element detachably connectable to the U-segment with frictional and / or positive engagement of the stile. In this embodiment, the U-segment is pushed over the spar. The U-segment is dimensioned such that it holds the spar with little play, which is also designed as a rectangular profile. The clamping element is then releasably connected to the U-segment, for example via a screw or a quick-release closure. Here, the clamping element under the influence of the spar against the U-segment curious; excited. The clamping element is preferably held in a receiving slot formed by the U-segment and open on one side. This receiving slot allows the insertion of the clamping element after the introduction of the spar in the U-segment and allows a cost-effective and easy production of the clamp for fixing the spacer strut or the support. The clamping element has an insert slot to be inserted into the receiving slot and at its opposite end a corresponding to the mounting eye of the clamp trained eye for inserting a screw. By screwing U-segment and clamping element with positive retention of the clamping element on the U-segment of the spar of the ladder is clamped in the U-segment. The strut or the spacer strut are preferably attached to the clamp via the same screw.

According to a further preferred embodiment of the present invention, the bottom has two with the rungs of the articulated conductors detachably connectable floor support and a auflagbare on this bottom flap. The bottom supports are firmly connected to the bottom flap and preferably have recessed sprouts at the end, which at least partially surround a rung when the frame is mounted. To simplify the assembly of the scaffold floor carriers also have in the field of sprout shots insertion ramps, which depart from the U-shaped sprout mounts obliquely outwards and facilitate accurate positioning of the individual rungs in the sprout shots. The bottom supports may additionally have at their respective ends pivotable safety hooks which engage behind the corresponding rung when mounted scaffold and thus prevent inadvertent detachment of the bottom plate of the rung. In known manner, the bottom plate is regularly divided, with a fixedly connected to the respective bottom support segment and a swivel-mounted bottom flap, which allows a passage through the floor.

The railing struts which are already mentioned above and can be connected to the articulated conductors are preferably fastened to the articulated conductors in an identical manner as the transverse or diagonal struts. There are usually at least two provided on both sides from the outside of the articulated ladders railing struts provided. It has been found to be useful to provide at least two railing struts with chipped ends, particularly in the preferred embodiment of cheeks that surround the floor and between are the parallel extending joint conductors. The abgeschöpfte end of the railing struts is dimensioned such that there are approximately equal clearances between the cheek and the overlying railing strut or railing strut and the next higher railing strut.

In the drawing, the embodiment of a climbing attachment is shown, which is constructed in the embodiment in the form of a scaffold 1. The framework 1 comprises two conventional 2 × 7 articulated conductors 2, ie articulated conductors each having seven rungs on the two connected by a joint 3 conductor portions 4 of the joint conductors 2. At a height of about 3 m is a bottom 6, which is still in closer to described manner at height equal rungs 8 of the two joint conductors 2 is supported.

The vertically extending articulated ladders 2 are interconnected by struts. There are cross struts 10, which extend between height equal rungs 8 of the mutual articular conductors 2. Furthermore, diagonal struts 12 are provided, which extend between the mutual hinge ladders 2 and bridge a height difference corresponding to four rungs. The front struts 10, 12 in FIGS. 1 and 2 are identified by the reference symbol a; the struts 10, 12 mounted on the opposite rear side are identified by the reference symbol b.

The upper transverse struts 10a, 10b serve not only to stiffen the framework 1, but also to form railing struts 14, by means of which the standing surface formed above the base 6 is delimited in the longitudinal direction. Between the upper ground strut 14 and the bottom 6 there is a second railing strut 16 which includes topped ends 17. The ablation is such that the middle railing strut 16 between itself and a cheek 18 laterally delimiting the bottom 6 forms the same clearance as the upper railing strut 14.

Below the bottom 6, only one transverse strut 10 is provided as the rear cross strut 10b, approximately at half the height of the bottom 6. This is located approximately at a height of 3 m. The transverse strut 10 is arranged at about 1.50 m.
All struts 10, 12, 14, 16 are mounted on threaded rods on the articular conductors 2, which enforce the inside hollow rungs 8 and are countered on the outside against the respective articular conductors 2, for example by wing or toggle screws optionally with the interposition of washers. The cheeks 18 are on the outside of the articular conductors 2, project beyond the bottom 6 by about 15 cm and over the width of the articular conductors 2 passing threaded rods are screwed against each other. These threaded rods further penetrate receiving openings of frontal cheeks 20, which define the bottom 6 parallel to the articular conductors 2. In this way, the cheeks 18 are connected to the frontal cheeks 20 to a unit and easy to mount on the frame 1.

The bottom 6 has - as the side view of FIG. 6 can be seen - two extending at the longitudinal edge of the bottom floor support 22, which are formed by downwardly open U-profiles and on which a two-part base plate 24, 26 is screwed. The bottom plate 24 is fixedly connected to the floor beams 22. The other part of the bottom 6 is formed by a pivotable flap 26, which is connected on one side only hingedly connected to one of the bottom support 22 and rests on the opposite bottom support 22. The plates 24, 26 of the bottom 6 are surmounted on both sides by the floor supports 22. At this outstanding end of the bottom support 22 have downwardly open rung receptacles 28 whose width corresponds in longitudinal extension of the bottom support 22 in about the width of the rungs 8. At their inner end, the sprout receptacles 28 each have an insertion ramp 30, which tapers to the sprout receptacle 28. The sprout receptacle 28 is bounded on the outside by a web 32 formed by free cutting of the sprout receptacle 28 from the U-profile formed by the bottom support 22. Between each other opposed webs 32 of each individual floor support 22, a pivot armature 34 is provided, which is pivotally mounted on the bottom support 22 and a securing pin 36 is formed, which engages behind the received in the rung receptacle 28 rung 8.

Attached to the lower conductor section 4 of the respective articulated conductors 2 are supports 38 which project beyond the articulated conductors 2 in the longitudinal direction (cf., FIG. 2) and in the transverse direction (cf., FIG. 3). The supports 38 have at their free end in each case a widened foot 40, which is mounted pivotably about a joint relative to the elongated profile of the support 38. Each foot 40 is adjustable in height relative to this elongated profile, in the embodiment shown via an engaging in the profile threaded rod.

At the other end, the support 38 is connected via a clamp 42 releasably connected to one of the spars 44 of the articulated conductor 2. The spar 44 has a rectangular cross-sectional shape and the clamp 42 comprises a U-segment 46 embracing this spar 44. The clamp 42 also has a receiving slot 48 into which a clamping member formed with a counter slot can be inserted, which is on the opposite side of the clamp 42 can be mounted on the one there obliquely outgoing mounting leg 50 under clamping inclusion of the spar 44. The clamping element and the mounting leg 50 have for this purpose holes 52 through which a screw can be passed, which also passes through an eye, which is recessed at the mounting end of the support 38.

Another clip 54, also clamping the spar 44, is located between the second and third rung 8. This clip 54 holds a spacer strut 56 extending between the strut 44 and the strut 38 and connected to both parts.

The supports 38 enclose between them and the spars 44 in the transverse direction an angle α of about 20 ° (see Fig. 3). In the longitudinal direction (see Fig. 2), this included between the support 38 and the spar 44 angle γ is about 14 °. In the width direction, the pillars 38 increase the footprint by about twice, i. The distance of the feet 40 in the transverse direction is about twice as large as the distance of ladder feet 58, which are attached to the ends of a cross member 60 attached to the lower end of the respective articulated ladders 2. In the longitudinal direction results in an increase in the footprint through the supports 38 to about 2.20 m. In this direction, the framework 1 has a length of about 1.60 m.

On the cross member 60 of the articulated conductors 2 rollers 62 are also detachably mounted, via which the raised at the other end frame 2 can be moved by loosening the supports 38.

For mounting the embodiment shown in FIGS. 1 to 3, first, the articulated conductors 2 are completely unfolded, so that the conductor sections 4 are aligned in extension to each other. Thereafter, the threaded rods are inserted into the desired rungs 8 and the struts 10, 12, 14, 16 pushed at their respective ends formed eyes over the free ends of the threaded rods and fixed by gags, which are in threaded engagement with the threaded rods. Thereafter, the clamps 54 are pushed with their U-shaped segments 46 on the bars 44 and connected via the clamping elements with the bars 44. In a plane perpendicular to the longitudinal extent of the spars each movement of the clamp 42 is prevented by the closed U-segment 46. In a direction perpendicular thereto by frictional connection of the clamp 42 on the spar 44. If such a frictional connection between the spar 44 and the clamp 42 is not sufficient, the spar at the mounting location for the clamp 42 may have a bore into which an the clamp 52 engages trained pin. Such a positive retention of the clamp 42 in the longitudinal direction of the Holmes 44 is also to be preferred in terms of a positionally accurate positioning and mounting of the clamp.

After securing the support 38 and the clamp 54 and the spacer strut 56, the preassembled scaffold has sufficient stability. Now the bottom 6 can be mounted. For this purpose, the bottom support 22 are brought with their sprout shots 28 on the selected sprouts 8.

In Fig. 5, the embodiment is illustrated with a more compact structure. In this case, the conductor sections 4 of the respective hinge conductors 2 are parallel to each other and to each other. The scaffold 1 shown in Fig. 5 then has only half the height of the embodiment shown in FIGS. 1 to 4. On lying below the bottom 6 cross struts was omitted. There are only approximately at the level of the bottom 6 crossing diagonal struts 12 and railing struts 14, 16 bolted to the joint conductors 2. On the additional supports 38 can be omitted; in the same way was waived on the rollers 62.

By exchanging two diagonally opposite clamps 42, a predominantly one-sided support of the framework 1 can be achieved. Thus, it is possible, for example, to provide parallel outgoing supports on both sides of the framework. These can, for example, in a setting up of the scaffold 1 close to a house wall to the side facing away from the wall of the house and thus strengthen the framework reinforced against the only possible Umkipprichtung. On the opposite side of the scaffold 1 is secured by the house wall against tipping over. For this purpose, the patented climbing attachment may comprise further correspondingly adapted clamps 42 which, at the desired angle, comprise attachment legs 50 projecting from the spar 44. It is also possible to provide the supports 38 with a support to be made on one side on the mutual end faces of the frame 1 in non-parallel alignment with each other. It is also conceivable to provide on one side two clamps 42 engaging at different heights on an identical spar 44, on which supports of different lengths, for example supports 15 extending in parallel, are mounted.

If desired, the framework can also be constructed with A-shaped ladder swung out. In this embodiment, the stability with respect to the embodiment shown in Fig. 5, in particular in the longitudinal direction of the frame 1 is increased.
