EP1712707A1 - Ladder for facilitating access to an open air swimming pool or for a container for liquids, granules or powders. - Google Patents

Abstract

The ladder has a part with a platform (4) and an upper hand rail (5), where the ladder is formed of two versions with the height of the platform (4) at 125cm and at 135cm. Plastic pins (2) with anti-slip patterns are fixed on a supporting structure. An axle of rotation is mounted on an outer side of a container for rotating an outer lower part of the ladder. Plastic supporting feet (3) are equipped with an end mounted telescopic lamp holder positioned in all the directions. A small plastic anti-slip platform is placed in an upper part of the uprights found above an upper edge of the container.

Description

The ladder, designed to be applied to pool / above-ground pool, open pit, containing liquids, granules or powders, has been studied and carried out to meet standards: -safety of use for users, facility installation and convenience for the use of accessories and appliances inside the basin (Fig.1 - Fig.2).

The load-bearing structure was made using two vertically mounted varnished metal tubes (part.1 Fig.1-2), on which are fixed, by steel screws, plastic plugs (part.2 Fig. 1-2) with a non-slip pattern at the top. To avoid user trauma and scratches due to friction, flathead screws with hexagon recessed, combined with a final flare on the upright, were used for this type of fixation.
To ensure adequate support of the uprights on the floor, a plastic support foot (part.3 Fig.1-2) is used inside and outside the pool / pool. a telescopic sleeve positioned in all directions, which allows a correct support on the laying plane, even if the surface is not perfectly flat.

In the upper part of the uprights above the upper edge of the basin was placed a small anti-slip plastic platform (part.4 Fig.1-2). This platform allows the user to stop climbing the ladder and start the descent on the opposite side in total safety, without having to perform unnatural movements or that involve the risk of instability or sliding steps .

In addition to fully meet the standards described, still in the upper final part of the uprights, were inserted and secured, thanks to metal screws, two other tubes that serve for the proper continuity of the uprights and form two side rails on the scale (part.5 Fig.1-2).

These solutions allow a safe use of the ladder for the user, with no possibility of continuity in the support of the feet on the ladder and the taking of hands on the uprights.

The standard of uniqueness of the scale is guaranteed by the axis of rotation (Fig.7) mounted on the outer side of the basin, which makes it possible to turn the outer lower part of the ladder towards the inside of the basin, by placing it vertically (Fig.4), and thus turning the part of the ladder comprising the platform and the upper guardrail (Fig.5), which is in the position of use inside the basin.

This device was realized thanks to the positioning of a metal support tube (part.6 Fig.1-2) connected by vices to two supporting columns of the pool / basin, so as to realize a solid anchoring frame for the scale. The scale must imperatively avoid being unstable during its use and during the phase of rotation of its portions (Fig.3-Fig.4 - Fig.5).

To this connecting tube were fixed the internal and external portions of the scale, using small nails with two metal tips, thus allowing the rotation of these portions, along the longitudinal axis of this connecting tube .

The scale, with this device of rotation is realized in two versions with the height of the platform to 125cm and 135cm, so as to adapt to the different versions of the swimming pools, which for their various capacities present different heights of the upper edge.

Claims (3)

Security of use
Use position with scale OPEN (Fig.3)
The particular typology of anchoring the ladder allows the attachment of the ladder to the struts of the pool / basin (Fig.7), to allow the realization of a rigid chassis. This frame avoids the possibility of falling from the user, due to the reversal of the ladder if it is subjected, during the use phase, to strong vertical and horizontal stresses.
The good stability of the ladder is also guaranteed, inside and outside the pool / pool, by a typology of ground support achieved through the use of plastic support feet, which increases the support surface, avoiding at the same time that the supports on the laying plan of the basin do not slide. Security to avoid the use of minors
Non-use position with CLOSED scale (Fig.4)
By turning up the lower part of the ladder placed on the outer side of the pool / pool, we have the possibility to put the ladder in a safe condition, making it impossible to access the children, which because of their small size could no longer climb the lower rungs.
This technical solution allows to prohibit access to the pool / pool, in case the adults responsible for controlling the children during the use of the pool / pool, are not present. Use of automatic devices and cleaners
Non-use position with ESCAMOTE scale (Fig.5 - Fig.6)
By rotating the part of the ladder in the swimming pool / basin outwards, the internal volume can be completely released, allowing the use of automatic devices for cleaning the water surface or for the various types of water. operations, which cause a stir, make the material contained can move and therefore without obstacles that make difficult or dangerous these operations.
