Campo técnico de la invención Technical field of the invention
La presente solicitud se relaciona con el campo de los muebles especialmente adaptados para niños y en particular proporciona una silla de enganche con un ajuste elástico de agarre. The present application relates to the field of furniture specially adapted for children and in particular provides a latch chair with an elastic grip fit.
Antecedentes de la invención Background of the invention
En el estado de la técnica, se conocen las sillas de enganche, que permiten sentar a un niño en el borde de una mesa. Estas sillas típicamente presentan dos brazos o porciones superiores y dos brazos o porciones inferiores que se acoplan a la superficie de la mesa. De esta manera, cuando se sienta al niño en la silla, el peso del menor ejerce una palanca que permite mantener la silla en su lugar. In the state of the art, coupling chairs are known, which allow a child to be seated on the edge of a table. These chairs typically have two upper arms or portions and two lower arms or portions that engage the table surface. In this way, when the child sits in the chair, the child's weight exerts a lever that keeps the chair in place.
Por ejemplo, el documento DE 3931549 describe una silla de enganche que se adapta a superficies de distinto espesor. Para esto, describe un armazón que posee una primera pieza en forma de U que define dos brazos superiores, un travesaño conectado a dichos dos brazos superiores y dos postes que se proyectan de manera vertical desde dichos brazos superiores. A fin de proporcionar la capacidad de adaptación, se disponen sendos resortes en dichos postes, que se conectan, a su vez, a correspondientes brazos inferiores. For example, DE 3931549 describes a harness saddle that adapts to surfaces of different thickness. For this, it describes a frame that has a first U-shaped piece that defines two upper arms, a crossbar connected to said two upper arms and two posts that project vertically from said upper arms. In order to provide the adaptability, two springs are arranged on said posts, which are connected, in turn, to corresponding lower arms.
Por otra parte, el documento US 4,586,746 describe una silla de enganche que posee un armazón formado por dos elementos en forma de U, cada uno que define un brazo superior y un brazo inferior, así como dos postes, cada uno que conecta verticalmente cada brazo superior con su correspondiente brazo inferior. La silla presenta, además, una superficie de asiento y una superficie de respaldo conectados a dichos elementos en forma de U. Esta silla presenta, además, dos elementos de sujeción que se deslizan a lo largo de dichos postes. Dichos elementos de sujeción pueden fijarse en su posición por medio de un mecanismo de cuña y resorte, que evita el movimiento hacia abajo de los elementos de sujeción. Dentro de los requerimientos normativos para su comercialización en Estados Unidos, se requiere que la silla soporte una serie de fuerzas, tanto en dirección longitudinal como vertical, sin ceder. Lo anterior, plantea un problema desde el punto de vista técnico que, sin embargo, no es resuelta por las sillas del estado de la técnica. En consecuencia, se requiere de una silla de tipo enganche que permita resolver el problema previamente explicitado. On the other hand, document US 4,586,746 describes a hitch chair that has a frame formed by two U-shaped elements, each one defining an upper arm and a lower arm, as well as two posts, each one vertically connecting each arm. upper arm with its corresponding lower arm. The chair also has a seat surface and a back surface connected to said U-shaped elements. This chair also has two fastening elements that slide along said posts. Said fasteners can be fixed in position by means of a wedge and spring mechanism, which prevents downward movement of the fasteners. Within the regulatory requirements for its commercialization in the United States, the chair is required to withstand a series of forces, both in longitudinal and vertical directions, without yielding. The foregoing raises a problem from the technical point of view that, however, is not solved by the chairs of the state of the art. Consequently, a hitch-type chair is required that allows solving the previously stated problem.

Descripción detallada de la invención Detailed description of the invention
En lo sucesivo, se describirá de manera detallada la silla de enganche (1 ) que es objeto de la presente solicitud, haciendo referencia para esto a las figuras que se acompañan. Hereinafter, the hooking saddle (1) that is the subject of the present application will be described in detail, making reference to the accompanying figures.
Tal como se ilustra en las figuras, el presente modelo de utilidad se refiere a una silla de enganche (1 ) que comprende, de manera esencial, un armazón (2) que posee dos brazos superiores (3a, 3b), dos brazos inferiores (4a, 4b), y sendos postes (5a, 5b) que conectan un brazo superior (3a, 3b) con su correspondiente brazo inferior (4a, 4b); una superficie de asiento (6) acoplada operativamente a dicho armazón (2); una superficie de respaldo (7) acoplada operativamente a dicho armazón (2); y dos elementos de tope (8a, 8b), cada uno conectado de manera deslizante a un poste (5a, 5b) correspondiente; en donde dichos elementos de tope (8a, 8b) se conectan de manera resiliente a dichos postes (5a, 5b), de forma tal que son empujados hacia dichos brazos superiores (3a, 3b). As illustrated in the figures, the present utility model refers to a latch chair (1) that essentially comprises a frame (2) that It has two upper arms (3a, 3b), two lower arms (4a, 4b), and two posts (5a, 5b) that connect an upper arm (3a, 3b) with its corresponding lower arm (4a, 4b); a seating surface (6) operatively coupled to said frame (2); a backing surface (7) operatively coupled to said frame (2); and two stop elements (8a, 8b), each slidingly connected to a corresponding post (5a, 5b); wherein said stop elements (8a, 8b) are resiliently connected to said posts (5a, 5b), in such a way that they are pushed towards said upper arms (3a, 3b).
Esta nueva geometría de la silla de enganche (1 ) posee la ventaja de que permite proporcionar cuatro puntos de contacto por debajo de la superficie a la cual se acopla la silla, a saber, dos extremos libres de los brazos inferiores (4a, 4b) y dos elementos de tope (8a, 8b). Esto permite soportar mayores fuerzas en dirección perpendicular a dicha superficie. Adicionalmente, al existir un empuje de dichos elementos de tope (8a, 8b) hacia dichos brazos superiores (3a, 3b) se aumenta la fuerza de contacto, y por tanto el rozamiento, entre la silla de enganche (1 ) y la superficie a la cual se acopla la silla. Esto último, permite soportar mayores fuerzas en dirección paralela al plano de dicha superficie. This new geometry of the hooking chair (1) has the advantage that it allows to provide four points of contact below the surface to which the chair is attached, namely, two free ends of the lower arms (4a, 4b) and two stop elements (8a, 8b). This makes it possible to withstand greater forces in a direction perpendicular to said surface. Additionally, since there is a push of said stop elements (8a, 8b) towards said upper arms (3a, 3b), the contact force, and therefore the friction, between the coupling saddle (1) and the surface a is increased. which the chair is attached to. The latter makes it possible to withstand greater forces in a direction parallel to the plane of said surface.
En el contexto de la presente solicitud, los términos relativos tales como superior, inferior, arriba, abajo, izquierda, derecha, adelante, atrás, entre otros, deben entenderse como referidos a una persona sentada en la silla de enganche (1 ) cuando la misma se encuentra normalmente en uso. In the context of the present application, the relative terms such as upper, lower, up, down, left, right, forward, backward, among others, should be understood as referring to a person sitting on the hitch chair (1) when the it is normally in use.
En el contexto de la presente solicitud, debe entenderse brazos como elementos estructurales que se proyectan en alguna dirección particular, definiendo un extremo libre en la dirección de proyección. En la realización preferida de silla de enganche (1 ) que se ilustra en las figuras, sin que esto limite el alcance de la presente solicitud, tanto los brazos superiores (3a, 3b) como los brazos inferiores (4a, 4b) se proyectan sustancialmente hacia adelante de desde la superficie de respaldo (7) o desde la superficie de asiento (6), respectivamente. Sin embargo, en otras realizaciones preferidas, dicha dirección de proyección puede formar un ángulo con el plano definido por la superficie a la cual se acopla la silla de enganche (1 ) o un ángulo diferente de 90 grados con la vertical, sin que esto limite el alcance de la presente solicitud. Con respecto a los brazos superiores (3a, 3b), la forma, geometría y material de los mismos, así como la dirección de proyección de dichos brazos superiores (3a, 3b) no limitan el alcance de la presente solicitud. Por ejemplo, tal como se ilustra en las figuras y sin que esto limite el alcance de la presente solicitud, dichos brazos superiores (3a, 3b) presentan una forma cilindrica que posee un eje recto. Sin embargo, pueden proporcionarse elementos adicionales o cambios de dirección en porciones de dichos brazos superiores (3a, 3b) sin que esto limite el alcance de la presente solicitud. Por ejemplo, y sin que esto limite el alcance de la presente solicitud, cada uno de dichos brazos superiores (3a, 3b) puede presentar una funda (10a, 10b) fabricada de un material antideslizante en sus correspondientes extremos libres. La forma, longitud y material de dichas fundas (10a, 10b) no limitan el alcance de la presente solicitud. Por ejemplo, y sin que esto limite el alcance de la presente solicitud, dichas fundas (10a, 10b) pueden cubrir desde el extremo delantero hasta el punto de conexión con el correspondiente poste (5a, 5b) de cada brazo superior (3a, 3b). Por otra parte, dichas fundas (10a, 10b) pueden fabricarse de un material antideslizante que se selecciona del grupo formado por gomas y siliconas, sin que esto limite el alcance de la presente solicitud. In the context of the present application, arms are to be understood as structural elements projecting in some particular direction, defining a free end in the projection direction.
