Description

Ladder construction structure snail.

Object of the invention

The model is referred to as the statement indicates to a structure for the construction of a spiral staircase in wood consisting of a single axis or vertical core with a helical or Solomonic style development formed by the succession of overlapping portions of parts or leftovers from the carpentry of said structure, with the added advantage that is made an important use of waste and that adopting a shape and a specific thickness a support column is created especially resistant and especially adaptable to successive wood contractions and the elastic effort to which they should respond by effect of wood flexibility and condition blown off the steps that are mounted on said column.

It is, according to the invention, a structure formed on a helical column of partial cores overlays that adopt a successive proportional form to the spine development due to overlap and shape insightful of said nuclei, intercalating between the steps and which in their case also constitute the core itself.

It will be understood as a spiral staircase, as exposed, those whose steps are located around a axis or "roller" on which they appear to rotate radially.

The nuclei are a fundamental part in the construction of this type of stairs and can be of different shapes and materials

They can be one-piece cores, usually in iron or wood or they may be partial cores that they are sandwiched between the steps, holding them.

Background of the invention

In the field of the state of the art the cores Partial wood can be in one piece, this being a technique widely used by almost all manufacturers, both in series, as artisans. For the manufacture of these cores should be used compact and dry wood, sometimes difficult to get and at rather high prices, or glue different thicknesses to get the desired measures. In the latter case there are to take good care of the gluing, because the longitudinal pressure at which these pieces are subjected, once the structure of the ladder, it could be your outburst.

These cores can have geometric figures very varied, from cylindrical to prismatic or various ornaments; but always with the common characteristic that its geometry is vertical. Of course, special work can be done that They would be complicated and expensive.

Description of the invention

To solve the exposed difficulties, the invention proposes to build the "roller" or partial vertical tree with helical development essentially integrated by cores compounds by superimposing pieces or fragments of wood approximately 4.5 - 3 cm thick, equivalent to the thickness of the wood of the steps, that is taking advantage of the remnants resulting from obtaining said steps, being several of said superimposed fragments those that integrate the separation between steps.

Another detail of the invention is that said pieces or fragments, remnants of the cuts of the steps are arranged stacked in staggered arrangement to seek development helical "curl" so that the resulting vertices, protrusions and leftovers are cut according to a tangential plane to the curve that marks the helical development of the "curl".

Another detail of the invention is that said pieces or fragments that are retal of said steps have a preference triangular or trapecial figure with through hole in the vertex of these pieces for integration into the corresponding heart of said "curl".

Depending on the development of the invention, advantageously obtain figures or bodies of varied geometry and easy handling; considerable use of wood and simple possibility of obtaining different figures.

With the invention it is equally possible to fight against a constructive inertia that, by force of repetition is already routine Hard and compact woods have to be used, for therefore, it is advisable to use the structuring form of the invention of core tightening to correct, with the passage of time and if necessary, slacks and cracks.

The solution is equally applicable to the construction of balusters, which when assembled by parts that can be interchangeable between them, allow combinations that offer varied aesthetics with a small number of basic pieces different.

Its main advantages are the ease of assembly, ease of adjustment and use of pieces, fragments, or remnants of wood, whose logical destiny is the fire.

A broader idea of the characteristics of the We will make the invention below, referring to the sheets of the drawings that are attached here, so somewhat schematic and only by way of example, representing the Preferred and vital details of the Model.

Preferred embodiment of the invention

In line with the previous representations for the construction of a spiral staircase as represented in Figures 6 and 7, the corresponding steps (1) are available, (2) of preferred triangular figure with arched end and vertex rounded with respective hole (4) for housing corresponding rigid axis (not shown) and of cores (3) cylindrical or cubic (6) separating and supporting said steps (1), (2) with the through hole (5) for said axis of rigidity; cores (3) and (6) that may be constituted of two symmetrical parts to close on said axis.

However, the solution proposed by the invention is constituted, to understand it based on the above, because the nuclei (9) are constituted by fragments, remnants or parts (10, 11, 12 ...) stacked, superimposed and staggered with respective matching hole (13) and with the result of an axis (a-b) oblique that delimits the cutting section of the remaining parts (14) (Fig. 5) of said fragments and that cutting them along the line delimited by the oblique axis (a-b) establish the continuity line (15) of the helical development of the "loop" (16) (Figs. 6 and 7).

Some fragments, according to the preferred idea of invention, which will have in the section equivalent to said "roller" (16), the triangular format of the steps (1, 2) of the vertex rounded with its corresponding hole (13) for the tree rigid, so that the profile will match the section of said steps (1, 2) at its junction with the cores (9).

Some fragments (10, 11, 12 ...) that will have the thickness of said steps (1-2) between 4.5-3 cm, since they are scrap leftovers from the cut of them in order to achieve an almost complete reuse of the wood used in the construction of the stairs giving it a aesthetic look whimsical, new and original.

Once nature is conveniently described of the invention is recorded for the appropriate purposes, that the same It is not limited to the exact details of this exhibition, but that on the contrary, it will introduce the modifications that are they consider appropriate, provided that the characteristics are not altered Essentials thereof, which are claimed below.
