Abstract

The invention relates to an improved mechanism for umbrellas and parasols, of the type that is equipped with a set of fabric-support rods at the upper end of a pole, which can pivot under the action of a set of push rods. According to the invention, one end of each push rod is articulated to the corresponding fabric-support rod, in the central segment thereof approximately, while the other end of each push rod is articulated to a ring that can move along the length of the pole. The invention is essentially characterised in that the mechanism is equipped with safety rods comprising: one end which is articulated to a second moving ring that moves along the pole in a segment between the first ring to which the push rods are articulated and the position of the shafts used to articulate the fabric-support rods; and an opposing end which is articulated to the outer zone of the rods that support the protective fabric.

Description

Mecanismo para paraguas y sombrillas perfeccionado Mechanism for umbrellas and umbrellas perfected
DESCRIPCIÓN Descripción de Ia invención El objeto de Ia presente invención tal y como se expresa en el enunciado de esta memoria descriptiva consiste en un mecanismo para paraguas y sombrillas perfeccionado.DESCRIPTION Description of the invention The object of the present invention as expressed in the statement of this specification consists of a mechanism for improved umbrellas and umbrellas.
Hasta Ia fecha, se conoce el uso paraguas y sombrillas, fijos o telescópicos, automáticos y manuales, todos ellos compuestos por un mástil, de una cierta longitud, sobre el que se dispone una estructura de varillas articulada que soporta una tela, de manera que al desplegarse dicha estructura forma una cúpula de protección frente a Ia lluvia en el caso de los paraguas o contra el sol, en el caso de las sombrillas.To date, it is known to use umbrellas and umbrellas, fixed or telescopic, automatic and manual, all of them composed of a mast, of a certain length, on which an articulated rod structure that supports a fabric is arranged, so that when said structure unfolds, it forms a dome of protection against rain in the case of umbrellas or against the sun, in the case of umbrellas.
Básicamente, esa estructura comporta una un conjunto de varillas sustentadoras de Ia tela o lona, articuladas en el extremo superior del mástil y dispuestas en forma radial, las cuales pivotan sobre su eje por Ia acción de un conjunto de varillas de empuje que se articulan por un extremo a Ia varilla sustentadora de Ia tela correspondiente, a Ia cual se acopla en su tramo central aproximadamente, y por el contrario a un anillo desplazable a Io largo del mástil.Basically, this structure involves a set of support rods of the fabric or canvas, articulated at the upper end of the mast and arranged radially, which pivot on its axis by the action of a set of push rods that are articulated by an end to the support rod of the corresponding fabric, to which it is coupled in its central section approximately, and on the contrary to a movable ring along the mast.
El principal problema estos mecanismos aparece cuando el viento entra por Ia parte inferior del paraguas. Si Ia fuerza con Ia que sopla el viento es superior a Ia resistencia que oponen las varillas que soportan Ia tela, Ia cúpula de protección del paraguas se gira quedando en posición invertida. En tales casos el sistema de varillaje se desforma drásticamente o incluso se rompe por Io que el paraguas o Ia sombrilla quedan inutilizados.The main problem with these mechanisms appears when the wind enters the lower part of the umbrella. If the force with which the wind blows is greater than the resistance that the rods that support the fabric oppose, the umbrella protection dome is turned in an inverted position. In such cases, the linkage system is drastically deformed or even broken so that the umbrella or the umbrella is rendered useless.
El novedoso mecanismo para paraguas y sombrillas cuya protección se recava, esta compuesto por un mástil, en el que se dispone una estructura de varillas articulada que soporta una tela tal como en los diseños convencionales, a saber, varillas sustentadoras de Ia tela, varillas de empuje y anillo desplazable por el mástil. Esta estructura de varillas convencional es complementada por una tercera varilla de seguridad que se articula por uno de sus extremos a un segundo anillo móvil que se desplaza sobre el mástil sobre un tramo comprendido entre el primer anillo donde se articulan las varillas de empuje y el punto donde se articulan las varillas de soporte de Ia tela, mientras que por el extremo contrario se articula a Ia zona exterior de Ia varilla que soporta Ia tela protectora.The novel mechanism for umbrellas and umbrellas whose protection is collected is composed of a mast, in which an articulated rod structure is provided that supports a fabric such as in conventional designs, namely, support rods of the fabric, rods of thrust and ring movable by the mast. This conventional rod structure is complemented by a third safety rod that is articulated by one from its ends to a second mobile ring that moves over the mast on a section between the first ring where the push rods are articulated and the point where the support rods of the fabric are articulated, while at the opposite end it articulates the outer zone of the rod that supports the protective fabric.
De esta manera Ia varilla de seguridad se constituye como un tirante entre el mástil y el extremo exterior de Ia varilla que soporta Ia tela protectora, que tiende a mantener replegada hacia dentro Ia estructura del paraguas a pesar de que se ejerza una gran presión dinámica por un golpe de viento incidente en Ia zona interior del mismo. Descripciones de los dibujosIn this way, the safety rod is constituted as a tie between the mast and the outer end of the rod that supports the protective fabric, which tends to keep the umbrella structure folded in despite the fact that a great dynamic pressure is exerted by an incident wind blow in the inner zone thereof.

Descripción de un caso prácticoDescription of a case study
El novedoso mecanismo para paraguas y sombrillas esta compuesto por un mástil (1), dotado de una empuñadura (2) en su extremo inferior, que en su extremo superior comporta una un conjunto de varillas sustentadoras (3) de Ia tela o lona (4) dispuestas en forma radial, las cuales pivotan sobre su eje (5) por Ia acción de un conjunto de varillas de empuje (6) que se articulan por un extremo a Ia varilla sustentadora de Ia tela (4) y por el contrario a un anillo desplazable (7) a Io largo del mástil (1).The novel mechanism for umbrellas and umbrellas is composed of a mast (1), equipped with a handle (2) at its lower end, which at its upper end involves a set of support rods (3) of the fabric or canvas (4 ) arranged radially, which pivot on its axis (5) by the action of a set of push rods (6) that are articulated at one end to the support rod of the fabric (4) and by the contrary to a movable ring (7) along the length of the mast (1).
Complementando las anteriores, dispone a Ia vez de una varilla de seguridad (8) que se articula por uno de sus extremos a un segundo anillo móvil (9) que se desplaza sobre el mástil (1) sobre un tramo comprendido entre el primer anillo (7) donde se articulan las varillas de empuje (6) y el punto donde se sitúan los ejes que articulan las varillas de soporte de Ia tela (5), mientras que por el extremo contrario se articula a Ia zona exterior de Ia varilla (10) que soporta Ia tela protectora. Complementing the above, it also has a safety rod (8) that is articulated at one of its ends to a second mobile ring (9) that moves over the mast (1) on a section between the first ring ( 7) where the push rods (6) are articulated and the point where the axes that articulate the support rods of the fabric (5) are located, while at the opposite end it is articulated to the outer zone of the rod (10 ) that supports the protective fabric.
