ITMS960004A1 - PORTABLE LADDER FOR SLOPES AND HIGH STANDING EVEN UNIQUE - Google Patents

Abstract

Monocular apparatus and optical-electronic virtual vision system that allows a simultaneous vision of an object not visible directly with one eye, leaving the other organ free for a vision of the surrounding reality. Virtual and simultaneously real vision device with separate images that allows the unconscious choice of one of the two visions under the effect of external stimuli. System obtained with television image transport technologies which, with monocular vision, allows simultaneous and selectable reading between two images (real and virtual).

Description

DESCRIPTION FOR INVENTIONS AND MODELS

Portable ladder for slopes! and also unique high support

. This artifact can? be used mainly by agricultural operators (pruners and fruit pickers), can? replace the ladder used for housework and can? be used by all operators who usually use the ladder for their work.

The traditional portable ladder? well known to all but has drawbacks such as:

1) it adapts badly to the ground;

2) can to give a support on the ground during the service;

3)? often difficult to find a stable support, especially on trees and the encumbrance area? too large resulting in breaking of small branches, buds or falling of fruit;

4) it has poor balance if it leans against an edge or poles etc. ; 5) even a small movement of the? operator can? cause complete imbalance with consequent falls.

The invention wants to solve the above mentioned drawbacks and therefore: 1) an easy adaptability? to the unevenness of the ground with maintenance delia verticality? of the tool;

2) during the service, if a point of support on the ground should yield the ladder, it follows the movement without losing the verticality? ;

3) can you? choose a single point of support at the top even on descending branches and away from the central stem, without affecting the fruits, buds or foliage;

4) with the final tip to ipsilon y, ap? Tilted forward you can? rest both on vertical surfaces and on edges or poles;

5) the movements of? operator are almost irrelevant to the stability? dell? tool that reacts uniquely resulting much more? sure of the traditional one.

L? Invention considers a different structure of the traditional ladder, it takes the form of two articulated support elements: a base, which receives the weight and adapts to the ground, and a? single vertical rod (bearing a system of pegs) which rests on the edge even only on one point. The base has a joint that allows you to orient the rod as you like and lock it to the base. desired angle and can? arrange all? course of the land even for steep slopes .L? vertical rod is placed, at the top, on one point or two using the Y-fork applied to the terminal. The terminal part of the? auction? extendable allowing you to use even more supports? tall on the same scale with very little bulk on the branches.

L? invention also offers the following options for greater stability? and use;

-1 Extension also differentiated of the tip;

-2 One or more? joints for use as a tripod;

-3 Tastes of safety at the ends? of the base;

-4 Mechanical actuator for the extension.

The project represented by the drawings (Plg. 1 - 2 - 3 - 4) constitutes the executive of the? invention in four possible heights? ; me. 3.30 / 4.30 / 5.50 i 6.90.

Describing fig. 1 drawn in scale 1: 20 we highlight:

a metal box base (1) 10 x 2 of suitable strength and weight cm long. 70 with central constraint (2) for fixing to the? vertical rod (6) that allows both freedom? to rotate second? angle a, and locking in the desired angular position. The base ? equipped with lateral stabilizers (3) and feet suitable for? support (4).

The rungs (5) are in non-slip aluminum with a diameter of 25 mm and an overall width of 40 cm. , which at the top narrows to 30 cm. ; are present up to the height of mi. 2.10 and each cm apart. 30, are they in solidarity with? central rod (6) and to the handrails (7) always in aluminum 0.5 x 35. L? central rod (6)? in aluminum box of suitable section (40 x 80) long mi. 2.10 measured from the joint (2) a! upper point (11). II tip (8) on extension (9)? in aluminum diameter 35 mm open with angle? of 60? tilted forward by 15? and of length equal to 25 cm. with classic terminal for support and for optional extension.

The extension (9) has a? 1 mi excursion. flows inside the? main auction (6) and d? maneuvered by a latch inside? main rod (6) operated by a crank (10) placed wings? height of 1 mi. off the ground . Point 13 highlights a possible articulation for use on a tripod.

Fig. 2 has the same type of staircase drawn on a scale of 1: 20 leaning against possible branches, with an overall height of m. 4.30 with base of cm. 90 resting on an inclined plane for degrees 7 with respect to? horizontal .

Figure 3 represents the same type of wake drawn on a scale of 1: 50 on a slope of 14 degrees having an overall height of ml. 5.50 and a base of ml. 1.10.

Figure 4 represents the same type of ladder drawn in scale 1: 50, simply leaning against a wall or eaves with the option of using extensions (1) on the final tip, length 6.90 m and base m. 1.30.

L? Does the invention work by solving the difficulties? of use of the traditional ladder, why? allows you to access with pi? safety, with lower temps, and with versatility? , to the high and higher areas? sides of trees, but also on balconies, roofs, poles, etc. .

Closure: INVENTION

The found so? conceived? susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept, furthermore all the details can be replaced with other technically equivalent ones.

Claims (1)

CLAIMS: -1 The portable ladder for pend? I? a? invention that considers a different structuring of the traditional scale,? concretized on two articulated support elements: a base that receives the weight and adapts to the ground and a? single vertical rod carrying a system of pegs, which leans up even on one point only. -2 Ladder according to the preceding claims which allows it to be used in almost all areas of the shaft by exploiting both the extension and the Y-shaped end and the articulated base. -3 Ladder according to the first claim which allows it to be transformed into a trestle even on very uneven ground. -4 Scale that according to the previous claims can? find a wide use also in the home. -5 Scale that can? be used by the world of! work that makes one? continuous use. -6 scale that using the new equilibrium system can? adapt to ideal solutions for specific work sectors, for civil and military services.
