Definitions

  • the invention relates to a stepladder, as used for example in swimming pool construction.
  • Such ladders initially run vertically upwards from the pool edge, are then bent towards the pool and then merge into a vertical section which ends in the water area via a further angled section.
  • the ladders are anchored at least in the area of the pool edge. In the water area they are often only against the pool wall.
  • the ladders - like any other ladder - consist of two side guide rails and at least one step connecting the guide rails.
  • the guide rails of known step ladders are in one piece and consist, for example, of steel, aluminum or plastic. This also applies to the steps, which are usually made in one piece with the corresponding sections of the guide rails.
  • step ladder also includes those ladders which are used, for example, in the household, in the craft sector or the like.
  • a disadvantage of the known swimming pool ladders is that - depending on the swimming pool size - different formats have to be provided. But the ladders are not only different in their height / length, for example depending on the water depth; the distance between the two vertical legs of the ladder also varies from case to case, depending on where the ladder can be attached to the pool edge, for example.
  • step ladders for example with handles, can only be made to order.
  • the object of the invention is to offer a step ladder, in particular for swimming pools, which enables simplified production and nevertheless - depending on the customer's request - can be individually adapted in size, shape and design.
  • the invention is based on the general idea of assembling the stepladder or its guide rails from discrete elements which - depending on the desired size, shape and number of steps - can be individually assembled and designed in such a way that they are mutually Allow formation of continuous guide rails with treads arranged between them.
  • the invention is based on the knowledge that this basic idea can be realized in a particularly simple and advantageous manner in that the individual segments are tubular and are designed with an axial through-hole, the segments of a guide rail arranged one behind the other being tensioned with one another via a rope connecting the segments , which runs through the axial through holes of the segments and is anchored at the end.
  • step ladder is composed of individual, discrete elements, any size and shape can be produced.
  • the stepladder runs exclusively linearly, its length can be varied very simply by assembling more and less segments into the corresponding guide rails.
  • additional transverse webs are preferably attached at the end between the guide rails in order to stiffen the ladder.
  • step ladders of the type mentioned above such as those used in swimming pool construction, ie step ladders with curved guide rails
  • the object according to the invention can be achieved in an analogous manner; it is then only necessary to form individual segments in a curved shape, preferably in the form of circular segments.
  • the stepladder is composed of a large number of individual segments according to the invention, overall it forms a more or less rigid system. This is achieved by the rope passed through the segments, that is tensioned at the ends of each guide rail under tensile load. In this way, the individual segments are lashed against each other, so that they then have a defined, largely stable shape.
  • An embodiment is particularly preferred in which adjacent segments of a guide rail are positively but releasably connected to one another.
  • the interlocking of the segments with each other increases the overall stability of the conductors.
  • each segment viewed in the direction of the through-hole, at one end with a recess which runs coaxially to the through-hole and at its opposite end with a projection which runs coaxially with the through-hole and whose cross-section is equal to or slightly smaller than that is the return.
  • the projection of one segment can be inserted into the recess of the adjacent segment, whereby the two are initially connected in a positive manner. If the guide rail is assembled in this way, the rope pulled through and braced at the end ensures that the geometry set in this way is retained even when the conductor is subjected to mechanical stress, for example by a person.
  • the conductor according to the invention has the further advantage that it has a certain intrinsic elasticity and, for example, can absorb mechanical stresses through a certain, reversible deformability when subjected to particularly high loads by a large or heavy person.
  • each segment should preferably have a circular cross section and be part of a cylindrical segment.
  • Cylindrical segments which - arranged one behind the other - complement each other to form a cylindrical guide rail, have the advantage that they can be easily gripped by hand and rule out the risk of injury from edges.
  • the invention further suggests that the projections of the segments - viewed in the axial direction of the through-hole - each have a greater length than the corresponding recesses. This has the consequence that the nested tubular segments have a certain distance from one another on the circumference, so that even in the event that a person grips the guide rails exactly in the region of adjacent segments, no pinching can occur if the segments, for example under high load, slightly deform each other.
  • each segment can also be designed in such a way that they taper slightly towards the inside of the segment, in this case the corresponding projections should also be slightly conical towards the free end, so that in any case a secure positive fit between adjacent segments is guaranteed.
  • the individual segments can also be braced against one another with the aid of the rope in different ways. While it is usually sufficient to anchor the rope mechanically at one end of each guide rail, at least at the other end of each guide rail, a tensioning device should be provided for the rope, with which the rope can be placed under a predefinable tension in order to secure the individual segments against each other.
  • a tensioning device can consist, for example, of a receiving part fastened to the rope end with an internal thread which can be screwed onto a threaded screw fastened, for example, to the edge of the pool, which shortens the effective rope length between its anchoring points.
  • the rope can be, for example, a metal, preferably a steel rope.
  • plastic ropes are also known, in particular plastic ropes which are twisted from several fibers, which have an extremely high tensile strength and can accordingly be used in the context of the invention.
  • Cylindrical segments are generally used for the vertical sections of a ladder.
  • semicircular segments with angled end sections can also be arranged along the vertical section, which in turn then run coaxially with the adjacent cylindrical segments and are positively connected to them are.
  • the design of the segments as plastic parts is particularly advantageous. They can then be manufactured, for example, by injection molding or extrusion. Their shape and color scheme is practically unlimited.
  • the respective last segments at the corresponding end of the step ladder should be designed with a device for locking the ladder on the floor, ceiling or wall side.
  • the last segments can be designed with a circumferential flange that is screwed opposite the pool edge.
  • the treads running between the guide rails can be formed in one piece with the corresponding segments, but can also be positively suspended in them, for example.
  • the design according to the invention makes it possible, depending on the customer's request, to arrange any number of steps in any design between the guide rails.
  • the reference numeral 10 represents the edge of a swimming pool and 12 its wall.
  • the guide rails 14 each have a first section 14a, which extends vertically from the pool edge 10, an adjoining semicircular section 14b, an adjoining, further vertical section 14c and finally at the lower end a quarter-circle section 14d on, the free end of which rests loosely against the pool wall 12.
  • Each guide rail 14 consists of a multiplicity of segments 18.
  • the segments 18 of the sections 14a, 14c are of cylindrical design, while the segments 18 of the sections 14b, 14d are designed as curved cylinders.
  • Each segment 18 has a central through hole 20. With the exception of the end segments 18, which are connected to the pool edge 10 or abut against the Bekken wall 12, each segment 18 is formed at one end with a recess 22 and at its other end with a projection 24. The recess 22 and the projection 24 run coaxially with the respective through hole 20, as can best be seen in FIG.
  • the projections 24 When viewed in the direction of the through bore 20, the projections 24 have a greater height than the recesses 22.
  • FIG. 4 further shows that also in the radial direction - with respect to the through-channel 20 - adjacent segments 18 are at a distance from one another, because the projections 24 have a smaller diameter than the segments 18 as a whole.
  • the segments 18, adjacent to the pool wall 10 each have a circumferential flange 18 a at their free ends, which serves to fix the corresponding guide rails 14 on the edge of the pool 10 with the aid of screws 30.
  • Figures 1 and 2 also show that two steps 32 are arranged between the adjacent guide rails 14.
  • the treads 32 each run between two adjacent segments 18 of each guide rail and are formed in one piece with them.
  • FIG. 3 shows an exemplary embodiment of a device for tensioning the rope 28.
  • the cable 28 is formed at the end with a section 28a which has a circumferential thread 28b.
  • a nut 34 with a corresponding internal thread can be screwed onto the thread 28b.
  • the nut 34 is supported against the segment 18 by a washer 36 in the region of an enlarged section 38 of the segment 18.
  • the cable 28, which is anchored at the other end in the same way within the corresponding segment 18, can be tensioned.
  • step ladder according to FIGS. 1 to 4 can be varied within a wide range, in that the individual segments are given a different shape, are shorter or longer, additional steps are arranged between adjacent segments, or else altogether more segments are connected one behind the other, so that the guide rails 14 are longer overall.
  • the stepladder could, for example, also have the shape of a normal handicraft or household ladder, that is to say, for example — in the side view — be reversed in V-shape, with a holding member connecting the two ladder legs.
  • a ladder can be built up by folding it down at the later apex and subsequent tensioning of the pulling rope, but when the pulling rope is relieved it can be folded up almost at will and thus easily transported.
