Description

Patín de suspensión para toldos fruncibles.Suspension skate for awnings.

Object of the invention

La presente invención se refiere a un patín de los utilizados para el fruncido de toldos mediante desplazamiento de un número indeterminado de patines sobre guías laterales de las que dichos patines quedan suspendidos.The present invention relates to a skate of those used for the gathering of awnings by displacement of an indeterminate number of skates on side guides of the that these skates are suspended.

El objeto de la invención es conseguir un patín que, sin el menor menoscabo en sus prestaciones funcionales, adopte una estructuración notablemente simplificada y una mayor facilidad de montaje, con la consecuente y positiva repercusión que ello supone a nivel económico.The object of the invention is to obtain a skate that, without the slightest impairment in its functional benefits, adopt remarkably simplified structuring and greater ease of assembly, with the consequent and positive impact that this Assumes at the economic level.

Background of the invention

En el ámbito de los toldos extensibles existen básicamente dos tipos, uno en el que la lona o toldo propiamente dicho se recoge sobre un eje giratorio, y otro en el que la lona se frunce o repliega sobre sí misma en el seno de un marco rectangular y fijo.In the field of extensible awnings there are basically two types, one in which the canvas or awning itself said is collected on a rotating shaft, and another in which the canvas is gather or fold over itself within a rectangular frame and fixed.

De forma mas concreta en los toldos del segundo tipo de los citados al que pertenece el objeto de la invención, los largueros del citado marco, es decir aquellos orientados en el sentido de plegado/extensión del toldo se materializan en perfiles acanalados de embocadura estrangulada, en el seno de los cuales se deslizan patines rodantes unidos articuladamente a respectivos soportes que a su vez se fijan convenientemente a perfiles transversales debidamente solidarizados a la lona, de manera que el deslizamiento de estos patines hacia uno de los extremos del marco provoca el plegado o recogida del toldo, mientras que su desplazamiento en sentido contrario provoca la extensión del mismo.More specifically in the awnings of the second type of those cited to which the object of the invention belongs, the stringers of the mentioned frame, that is to say those oriented in the direction of folding / extension of the awning materialize in profiles strangled spout grooves, within which sliding roller skates jointly attached to respective brackets that in turn conveniently attach to profiles duly sympathetic to the canvas, so that the sliding of these skates towards one end of the frame causes the folding or collection of the awning, while its displacement in the opposite direction causes the extension of the same.

De forma mas concreta cada uno de estos patines está constituido mediante un eje metálico sobre el que están montadas con libertad de giro dos ruedas de plástico, entre las que se sitúa uno de los extremos de un brazo o bieleta también de plástico, convenientemente perforada al efecto, con una perforación en su otro extremo para el paso de un segundo eje, también metálico, montado sobre una pareja de orejetas de que está provisto el soporte también de plástico de fijación al perfil asociado a la lona.More specifically each of these skates it is constituted by a metallic axis on which they are two plastic wheels mounted with freedom of rotation, between which one of the ends of an arm or connecting rod is also located plastic, conveniently perforated for that purpose, with a perforation at its other end for the passage of a second axis, also metallic, mounted on a pair of lugs provided the support also of plastic fixing to the profile associated with the canvas.

Con independencia de la presencia en el patín de dos tipos de materiales distintos, metálico y plástico, su proceso de montaje resulta complejo por cuanto el primero de los ejes citados debe estar dotado de una cabeza en funciones de tope y debe ser sometido por su otro extremo a una expansión radial para retener una arandela también en funciones de tope, realizándose esta expansión radial una vez que las tres piezas de plástico que constituyen el eje, el brazo, la bieleta y las dos ruedas, han sido debidamente montadas. Un problema similar se produce a nivel del segundo eje.Regardless of the presence on the skate of two different types of materials, metallic and plastic, their process assembly is complex because the first of the axes cited must be provided with a head in functions of butt and must be subjected to radial expansion at its other end to retain a washer also in stop functions, performing this radial expansion once the three pieces of plastic that constitute the axle, the arm, the connecting rod and the two wheels, have been properly mounted. A similar problem occurs at the level of second axis

Todo ello encarece el patín, dificulta considerablemente su montaje y hace prácticamente imposible su reparación ante un fallo en cualquiera de sus componentes.All this makes the skate more expensive, makes it difficult its assembly considerably and it makes its repair before a failure in any of its components.

Description of the invention

El patín de suspensión para toldos fruncibles que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados.The suspension skid for awnings that the invention proposes resolves in a fully satisfactory manner the problem described above, in the different aspects commented.

Para ello y partiendo de una estructuración básica similar a la de un patín convencional, en cuanto a la existencia de un eje portaruedas, un brazo o bieleta que relaciona dicho eje con un segundo eje, y un soporte sobre el que está montado dicho segundo eje y que a su vez es fijable al perfil transversal correspondiente de la lona, la invención consiste en hacer ambos ejes monopieza, por un lado con la pareja de ruedas que constituyen el patín propiamente dicho y por otro con la pareja de orejetas correspondiente al soporte, de manera que se trata de piezas obtenidas integralmente en plástico, en una fase única de moldeo o inyección, que no requiere de ninguna operación complementaria posterior.To do this and based on a structuring basic similar to that of a conventional skate, as for the existence of a shaft holder, an arm or connecting rod that relates said axis with a second axis, and a support on which it is mounted said second axis and which in turn is fixable to the profile corresponding cross section of the canvas, the invention consists of make both axles one-piece, on the one hand with the pair of wheels that they constitute the skate proper and on the other with the couple of lugs corresponding to the support, so that it is parts obtained entirely in plastic, in a single phase of molding or injection, which does not require any operation complementary later.

Complementariamente se ha previsto que el brazo o bieleta presente sus dos orificios, para paso de los mencionados ejes, abiertos hacia bordes contrarios del propio brazo y con su embocadura ligeramente estrangulada, de manera que el acoplamiento de los ejes no se realiza de forma axial, como es convencional, sino de forma radial, quedando las citadas piezas debidamente unidas a través de una maniobra extraordinariamente rápida y sencilla, que permite además un posterior desmontaje, en caso de que sea necesario, sin mas que forzar levemente la estrangulación de dichas aberturas de los orificios en contra de la naturaleza elástica del material constitutivo del brazo o bieleta.In addition, it is planned that the arm or connecting rod present its two holes, to pass the mentioned axes, open towards opposite edges of the arm itself and with its slightly strangled mouthpiece, so that the coupling of the axes is not performed axially, as is conventional, but radially, leaving the aforementioned pieces properly united through an extraordinarily fast maneuver and simple, which also allows further disassembly, in case of that is necessary, without more than slightly straining the strangulation of said hole openings against nature elastic of the constituent material of the arm or link.

Preferred Embodiment of the Invention

A la vista de las figuras mencionadas y en particular de la figura 5, puede observarse como el patín que la invención propone está constituido mediante la combinación funcional de tres únicas piezas, todas ellas de material plástico y consecuentemente fácilmente obtenibles por moldeo.In view of the mentioned figures and in particular of figure 5, can be seen as the skate that the proposed invention is constituted by combining functional of only three pieces, all of them of plastic material and consequently easily obtainable by molding.

Una de estas piezas, la representada en detalle en la figura 1, consiste en una pareja de ruedas gemelas (1) relacionadas entre sí con carácter monopieza con la colaboración de un eje intermedio (2).One of these pieces, the one represented in detail in figure 1, it consists of a pair of twin wheels (1) related to each other with a single character with the collaboration of an intermediate shaft (2).

La segunda pieza consiste en un soporte materializado en una placa (3), alargada, dotada en uno de sus extremos de un orificio (4) para su fijación por atornillamiento al perfil asociado a la lona y no representado en los dibujos, y emergiendo con carácter monopieza de dicha placa (3) una pareja de orejetas (5), paralelas, también relacionadas con carácter monopieza mediante un eje (6), que en situación de montaje y como se observa en la figura 5 es paralelo al eje (2) anteriormente citado.The second piece consists of a support materialized on a plate (3), elongated, equipped with one of its ends of a hole (4) for fixing by screwing the profile associated with the canvas and not represented in the drawings, and emerging with a single piece of said plate (3) a pair of lugs (5), parallel, also related to character monopieza by means of an axis (6), that in situation of assembly and as it observed in figure 5 is parallel to the axis (2) above aforementioned.

Estas dos piezas representadas en las figuras (1 y 2), se relacionan entre sí mediante el brazo o bieleta (7) de las figuras 3 y 4, brazo con alojamientos (8-8') para los ejes (2 y 6) de las piezas que va a relacionar de forma articulada, pero estando estos alojamientos abiertos lateralmente, configurando ranuras inclinadas y contrapuestas (10), de configuración ligeramente divergente hacia su embocadura (11), como se observa en particular en la figura 4, contando con una ligera estrangulación (9) próxima a su fondo que delimita la zona de ubicación del correspondiente eje, a la que se accede a través de dichas ranuras inclinadas y contrapuestas (10), de manera que la anchura de las embocaduras (11) es ligeramente superior al diámetro de los ejes, con respecto a los que las estrangulaciones internas (9) están ligeramente infradimensionadas.These two pieces represented in the figures (1 and 2), are related to each other by means of the arm or connecting rod (7) of the Figures 3 and 4, arm with housings (8-8 ') for the axes (2 and 6) of the pieces to be related in a way articulated, but these housings being open laterally, configuring inclined and opposed grooves (10), of slightly divergent configuration towards its mouth (11), as it is observed in particular in figure 4, with a slight strangulation (9) near its bottom that delimits the zone of location of the corresponding axis, which is accessed through said inclined and opposed grooves (10), so that the width of the openings (11) is slightly larger than the diameter of the axes, with respect to which the internal strangulations (9) are slightly under-sized.

De esta manera el sobredimensionamiento de la embocadura de la ranura de acceso (10) y una acusada inclinación prevista para la misma confieren a la pieza (7) un aspecto de "S", hace que el acoplamiento de los ejes (2 y 6) resulte sumamente rápido y sencillo, debiendo ejercerse sobre ellos una cierta presión para sobrepasar la estrangulación (9) citada, que hace que se mantengan estables en sus definitivos alojamientos de trabajo (8-8'), de los que también son susceptibles de salir ante una eventual necesidad de desmontaje para sustitución de una cualquiera de las tres piezas citadas, que por cualquier causa pueda haber resultado dañada.In this way the oversize of the mouth of the access slot (10) and a sharp inclination provided for it give the piece (7) an aspect of "S", makes the coupling of the shafts (2 and 6) result extremely fast and simple, having to exercise on them a some pressure to overcome the throttling (9) mentioned, which makes them stay stable in their definitive accommodations of work (8-8 '), of which they are also susceptible to leave before a possible need for disassembly for replacement of any one of the three cited pieces, which for any cause may have been damaged.
