Este soporte al igual que otros dispositivos similares formados de acuerdo con la técnica anterior, está sujeto a tensiones combinadas de flexión y compresión de los elementos de que se compone. De éstos, el elemento interior, que es necesariamente de menores dimensiones, de forma que pueda colocarse dentro del elemento exterior, es el elemento que está sometido a las tensiones más críticas.This support just like other devices similar formed according to the prior art, is subject at combined bending and compression stresses of the elements of It is composed. Of these, the inner element, which is necessarily of smaller dimensions, so that it can be placed within the outer element, it is the element that is subject to The most critical tensions.
Se han desarrollado diversas alternativas para asegurarse de la resistencia del elemento interior.Various alternatives have been developed for ensure the resistance of the inner element.
La primera y más importante es la de hacer el elemento interior de un material diferente y más fuerte, aunque más pesado, que el material que se usa para la construcción del elemento exterior. Típicamente, el elemento exterior se hace de aleación de aluminio y el elemento interior se hace de acero. Además, es habitual hacer el elemento interior considerablemente más corto que el elemento exterior.The first and most important is to do the inner element of a different and stronger material, although more heavy, that the material used for the construction of the element Exterior. Typically, the outer element is made of alloy Aluminum and the inner element is made of steel. It is also usual to make the inner element considerably shorter than The outer element.
Aunque, por una parte, todas estas disposiciones favorecen la resistencia del soporte, aunque esté sometido a grandes cargas, por otra parte comprometen su peso, maniobrabilidad y adecuación a grandes ajustes longitudinales, así como su capacidad, como conjunto, para resistir cargas combinadas de tensión de flexión y compresión.Although, on the one hand, all these provisions they favor the resistance of the support, although it is subjected to large loads, on the other hand compromise its weight, maneuverability and adaptation to large longitudinal adjustments, as well as its ability, as a whole, to resist combined stress loads of flexion and compression.
En el documento EEUU 5388888 se describe un soporte telescópico que tiene las características contenidas en el preámbulo de la reivindicación principal.US 5388888 describes a telescopic stand that has the characteristics contained in the preamble of the main claim.
La principal tarea de la invención es proporcionar un soporte, particularmente para obras de edificación, que esté diseñado estructural y funcionalmente para superar las desventajas tratadas con referencia a la técnica anterior mencionada.The main task of the invention is provide support, particularly for building works, that is structurally and functionally designed to overcome disadvantages treated with reference to the prior art mentioned.
Un objeto importante de la presente invención es proporcionar un soporte telescópico en el cual se eviten los problemas de desgaste relacionados con el ajuste con tuercas anulares.An important object of the present invention is provide a telescopic stand in which the wear problems related to nut adjustment annular

Resultarán más claras las características y ventajas adicionales de la invención a partir de la descripción de una realización preferida, pero no exclusiva, de la misma, indicada a título de ejemplo no limitativo, haciendo referencia a los dibujos anexos, en los cuales:The characteristics will be clearer and additional advantages of the invention from the description of a preferred but not exclusive embodiment thereof, indicated by way of non-limiting example, referring to the drawings annexes, in which:
la Figura 1 muestra, en una vista en perspectiva, un soporte telescópico, particularmente para uso en edificación, con una estructura según la invención.Figure 1 shows, in a perspective view, a telescopic stand, particularly for building use, with a structure according to the invention.
la Figura 2 muestra, en corte longitudinal, una parte de un soporte según la invención; yFigure 2 shows, in longitudinal section, a part of a support according to the invention; Y
la Figura 3 muestra el soporte de los dibujos previos en corte transversal.Figure 3 shows the support of the drawings previous in cross section.
Haciendo referencia particular a los dibujos descritos anteriormente, se indica generalmente por 10 un soporte telescópico particularmente para obras de edificación, con una estructura según la invención.Making particular reference to the drawings described above, a support is generally indicated by 10 telescopic particularly for building works, with a structure according to the invention.
El soporte 10 comprende un elemento tubular interior 11, deslizable telescópicamente dentro de un elemento tubular exterior 12. Los elementos 11 y 12 están dotados en sus extremos de placas de soporte 13 conformadas.The support 10 comprises a tubular element interior 11, telescopically slidable within an element outer tubular 12. Elements 11 and 12 are provided in their ends of shaped support plates 13.
Como se puede ver en la Figura 3, el elemento interior 11 está hecho de aleación de aluminio extrusionado y tiene, en sección transversal, una serie de corrugaciones recurrentes que se extienden prácticamente en forma continua longitudinalmente y distribuidas a intervalos regulares alrededor de su periferia interior y de su periferia exterior. Se aumenta así la sección transversal resistente que está sometida a esfuerzos de compresión, y también se logra una rigidización del elemento interior del soporte, lo cual aumenta su resistencia.As you can see in Figure 3, the element Interior 11 is made of extruded aluminum alloy and it has, in cross section, a series of corrugations recurring that extend virtually continuously longitudinally and distributed at regular intervals around its inner periphery and its outer periphery. This increases the resistant cross section that is subjected to stresses of compression, and stiffening of the element is also achieved inside the support, which increases its resistance.
Las corrugaciones tienen una forma aproximadamente sinuosidal con respecto a un círculo medio del elemento 11 y se forman, al menos en algunas de las aristas exteriores, partes de rosca de tornillo, de manera que constituyen una pluralidad de sectores roscados 17.Corrugations have a form approximately sinuosidal with respect to a middle circle of element 11 and are formed, at least in some of the edges outer, screw thread parts, so that they constitute a plurality of threaded sectors 17.
Las corrugaciones definen una pluralidad de primeras partes reentrantes 14 dispuestas circunferencialmente a intervalos de 45º y un perfil exterior que tiene entrantes longitudinales 15 que definen aristas o primeros salientes 16, también espaciados circunferencialmente con una separación de 45º.Corrugations define a plurality of first reentrant parts 14 arranged circumferentially to 45º intervals and an external profile that has incoming longitudinal 15 defining edges or first projections 16, also circumferentially spaced with a separation of 45º.
Alternativamente las corrugaciones exteriores pueden ser formadas por fresado y, en este caso, el elemento tubular interior está provisto inicialmente de una rosca externa continua que es subsiguientemente fresada para producir entrantes longitudinales 15 como se indica anteriormente.Alternatively outer corrugations they can be formed by milling and, in this case, the element Inner tubular is initially provided with an external thread continuous which is subsequently milled to produce starters Longitudinal 15 as indicated above.
El elemento tubular 12 exterior tiene una sección transversal conformada con un perfil interior que define segundos salientes y segundas partes reentrantes, 18 y 19 respectivamente.The outer tubular element 12 has a section cross shaped with an inner profile that defines seconds outgoing and second reentrant parts, 18 and 19 respectively.
Existe por tanto una serie de corrugaciones recurrentes que se extiende prácticamente en forma continua longitudinalmente y espaciadas a intervalos regulares alrededor de la circunferencia del elemento con una forma aproximadamente sinusoidal con respecto al círculo medio del elemento y con un perfil complementario al de las corrugaciones del elemento interior 11.There is therefore a series of corrugations recurring that extends virtually continuously longitudinally and spaced at regular intervals around the circumference of the element with a shape approximately sinusoidal with respect to the middle circle of the element and with a complementary profile to the corrugations of the inner element eleven.
Como puede verse en la figura 3, cuando el elemento interior 11 se ha colocado dentro del elemento exterior 12, los primeras salientes 16 del elemento interior 11 se colocan en las segundas partes reentrantes 19 del elemento exterior 12, de forma que el soporte 10 tiene una pluralidad de puntos de contacto entre los dos elementos tubulares 11 y 12 aun en la presencia de oscilaciones mínimas, asegurando un considerable aumento de la estabilidad de la estructura en comparación con los sistemas convencionales.As can be seen in Figure 3, when the inner element 11 has been placed inside the outer element 12, the first projections 16 of the inner element 11 are placed in the second reentrant parts 19 of the outer element 12, of such that the support 10 has a plurality of contact points between the two tubular elements 11 and 12 even in the presence of minimum oscillations, ensuring a considerable increase in the structure stability compared to systems conventional.
Un sector roscado del primer saliente 16 es eliminado, por ejemplo, por un proceso de aplanado mecánico, de forma que se produce una superficie 16a plana y ligeramente en entrante.A threaded section of the first shoulder 16 is removed, for example, by a mechanical flattening process, from so that a flat 16th surface is produced and slightly in incoming.
Se ajusta la extensión del elemento interior 11 a partir del elemento exterior 12 por medios de fijación que pueden cerrar el deslizamiento relativo de los elementos en al menos una de las dos direcciones de deslizamiento. Se usa para esta finalidad una tuerca anular 20 encajada por acoplamiento de roscas macho-hembra en las partes de rosca interrumpida del elemento interior 11 y, en condiciones de uso se detiene a tope apoyándose en una placa de forma 21 fijada firmemente a la parte superior del elemento exterior 12.The extension of the inner element 11 is adjusted to from the outer element 12 by fixing means that can close the relative sliding of the elements in at least one of the two sliding directions. It is used for this purpose an annular nut 20 fitted by thread coupling male-female in the interrupted thread parts of the inner element 11 and, under conditions of use, stops fully leaning on a plate of form 21 firmly fixed to the part upper outer element 12.
La placa de forma 21 está hecha de metal tenaz para evitar problemas de desgaste de la superficie de apoyo entre la placa 21 y la tuerca anular 20 debidos al rozamiento mutuo durante las operaciones de extensión-ajuste.The form plate 21 is made of tough metal to avoid problems of wear of the support surface between the plate 21 and ring nut 20 due to mutual friction during extension-adjustment operations.
Al término del ajuste, el conjunto constituido por el elemento interior 11 y por la tuerca anular 20 es fijado en la posición deseada por un gancho elástico 22 que está articulado a la parte superior del elemento 12 y se encaja en una pestaña inferior 23 de la tuerca anular 20.At the end of the adjustment, the set constituted by the inner element 11 and by the ring nut 20 is fixed in the desired position by an elastic hook 22 that is articulated to the top of element 12 and fits into a tab bottom 23 of the ring nut 20.
Un fiador de seguridad 25, fijado en un orificio roscado 24 correspondiente en la superficie plana 16a del elemento interior 11, se extiende en la segunda parte reentrante 19a del elemento exterior 12.A safety catch 25, fixed in a hole corresponding thread 24 on the flat surface 16a of the element interior 11, extends into the second reentrant part 19a of the outer element 12.
Una placa 27 adecuada para formar un sujeción para el fiador 25 está fijada en la segunda parte reentrante 19a, en la vecindad del extremo superior del elemento exterior 12 por medio de tornillos 26.A plate 27 suitable for forming a fastener for the catch 25 is fixed in the second reentrant part 19a, in the vicinity of the upper end of the outer element 12 by screw means 26.
El fiador 25 y la placa 27 aseguran ambos que sea completamente imposible para el elemento interior 11 deslizarse saliendo del elemento exterior 12, asegurando de este modo la estabilidad del conjunto en su utilización.The latch 25 and plate 27 both ensure that it is completely impossible for the inner element 11 to slide leaving the outer element 12, thus ensuring the stability of the assembly in its use.
Ventajosamente, los elementos interior y exterior 11 y 12 pueden hacerse de aleación de aluminio o de otra aleación ligera.Advantageously, the interior and exterior elements 11 and 12 can be made of aluminum alloy or other alloy light
Se ha encontrado que la presente invención ha conducido en la práctica al logro de los objetos propuestos.It has been found that the present invention has led in practice to the achievement of the proposed objects.
Además, se proporciona una estructura de soporte que evita los problemas de desgaste relacionados con la operación de ajustar la extensión relativa de los elementos interior y exterior.In addition, a support structure is provided which avoids wear problems related to the operation of adjusting the relative extent of the interior elements and Exterior.
Adicionalmente, el soporte 10 resuelve el problema de deslizamiento del elemento interior 11 saliéndose del elemento exterior 12 así como los problemas de levantamiento con respecto a la estabilidad reducida en el caso de que el soporte 10 sea utilizado con el elemento 11 extendiéndose demasiado lejos del elemento exterior 12; las partes de los dos elementos tubulares que interactúan son así suficientes para asegurar el equilibrio y estabilidad del conjunto con respecto al eje vertical.Additionally, support 10 resolves the problem of sliding of the inner element 11 leaving the outer element 12 as well as lifting problems with with respect to the reduced stability in case the support 10 be used with element 11 extending too far from the outer element 12; the parts of the two tubular elements that interacting are thus sufficient to ensure balance and set stability with respect to the vertical axis.
La estructura es simple y económica.The structure is simple and economical.
