DESCRIPCIÓN DESCRIPTION
DISPOSITIVO DE RODADURA PARA SILLAS CHAIR BEARING DEVICE
Objeto de la invención. Object of the invention.
La presente invención se refiere a un dispositivo de rodadura para sillas, que esta diseñado para facilitar el movimiento, desplazamiento y arrastre de las sillas convencionales del hogar, oficina, etc sin esfuerzos, ruidos molestos, y desgaste de las patas de las sillas o de los suelos especialmente de madera u otros materiales. The present invention relates to a rolling device for chairs, which is designed to facilitate the movement, displacement and drag of conventional chairs of the home, office, etc. without effort, annoying noise, and wear of the legs of the chairs or of floors especially of wood or other materials.
Campo de aplicación de la invención. Este dispositivo de rodadura es aplicable en el plano inferior de apoyo de las patas de las sillas, acoplado dentro de las patas, ya sea haciendo un orificio o de cualquier otra manera . Field of application of the invention. This rolling device is applicable in the lower plane of support of the legs of the chairs, coupled inside the legs, either making a hole or in any other way.
Antecedentes de la invención. Background of the invention.
Son numerosos los dispositivos que se utilizan para facilitar el movimiento o arrastre de sillas que normalmente están hechos con unas ruedas giratorias fijas que conforman los medios de apoyo de la silla con el suelo. Estos dispositivos tienen el inconveniente de que la silla no se puede quedar fija en el suelo porque siempre esta apoyada sobre las ruedas giratorias que facilitan que la silla se deslice con demasiada facilidad cuando se encuentra en uso lo que suele ser bastante molesto. Existen varios dispositivos de rodamientos flotantes parecidos que se utilizan para deslizar por ejemplo tableros, en cadenas de montaje pero que presentan los mismos inconvenientes que las ruedas giratorias fijas.
Descripción de la invención. There are numerous devices that are used to facilitate the movement or drag of chairs that are normally made with fixed swivel wheels that make up the support means of the chair with the floor. These devices have the disadvantage that the chair cannot be fixed on the floor because it is always resting on the swivel wheels that make it easy for the chair to slide too easily when it is in use, which is usually quite annoying. There are several similar floating bearing devices that are used to slide boards, for example, on assembly lines but which have the same drawbacks as fixed swivel wheels. Description of the invention
Este dispositivo de rodadura para sillas está compuesto de una carcasa cilindrica, una esfera, un separador y un muelle. This rolling device for chairs is composed of a cylindrical housing, a sphere, a separator and a spring.
La carcasa presenta una boca por la que emerge parcialmente la esfera que es deslazada hacia el exterior de la carcasa por la actuación del muelle sobre el separador que está situado por encima de la mencionada esfera. Cada silla llevará un dispositivo de rodadura en cada pata para su desplazamiento mediante la rodadura de las esferas. The housing has a mouth through which the sphere that is displaced towards the outside of the housing partially emerges from the action of the spring on the separator that is located above said sphere. Each chair will carry a rolling device on each leg for movement by rolling the spheres.
La finalidad de este dispositivo es que cuando una silla no está ocupada el muelle del mecanismo que presiona la bola contra el suelo provoca que la silla se eleve unos milímetros y que dicha silla quede apoyada sobre el suelo mediante las esferas de los dispositivos de rodadura permitiendo el giro de dichas esferas que la silla se deslice con gran facilidad y sin rozaduras ni ruidos molestos. Cuando la silla está ocupada o soporta cierto peso, por ejemplo el de una persona, los muelles de los mecanismos de rodadura se comprimen descendiendo el conjunto de la silla hasta que las patas de la misma tocan el suelo y las esferas se ocultan dentro del dispositivo correspondiente, quedando dicho dispositivo inhabilitado y la silla fija por el contacto de las patas con el suelo, sin movimientos inesperados o molestos, es decir como una silla normal y corriente. The purpose of this device is that when a chair is not occupied the spring of the mechanism that presses the ball against the ground causes the chair to rise a few millimeters and that said chair is supported on the ground by means of the spheres of the rolling devices allowing The rotation of these spheres makes the chair slide very easily and without scratches or annoying noises. When the chair is occupied or supports a certain weight, for example that of a person, the springs of the rolling mechanisms are compressed by lowering the whole chair until the legs of the chair touch the ground and the spheres are hidden inside the device corresponding, said device being disabled and the chair fixed by the contact of the legs with the floor, without unexpected or annoying movements, that is to say as a normal and current chair.
En el momento de levantarse de la silla ésta se eleva gracias a los dispositivos volviendo a quedar apoyada sobre el suelo por medio de las esferas de los dispositivos de rodadura lo que permite su movimiento y desplazamiento. Esto facilitará por ejemplo entrar y salir con la silla de una mesa con espacio ajustado, mover la silla para barrer, etc. At the time of getting up from the chair, it rises thanks to the devices once again resting on the ground by means of the spheres of the rolling devices, which allows their movement and movement. This will make it easier, for example, to enter and leave the chair at a table with tight space, move the chair to sweep, etc.
