Description

Dispositivo de manipulación para camas Handling device for beds

OBJECT OF THE INVENTION

La presente invención se refiere a un dispositivo que ha sido especialmente concebido para facilitar la manipulación de camas, ya sean canapés de camas convencionales o para la manipulación de una cama nido, concretamente de la cama inferior. The present invention relates to a device that has been specially designed to facilitate the handling of beds, whether they are conventional bed couches or for the handling of a trundle bed, specifically of the lower bed.

Es también objeto de la invención proporcionar un dispositivo de fácil acceso y manipulación, que de forma suave, permita mover la cama de que se trate cuando el dispositivo se encuentre en situación operativa, mientras que en situación inoperante la cama quede perfectamente inmovilizada y estabilizada. It is also the object of the invention to provide an easy access and manipulation device that, in a smooth way, allows the bed in question to be moved when the device is in an operative situation, while in an inoperative situation the bed is perfectly immobilized and stabilized.

BACKGROUND OF THE INVENTION

En el ámbito de aplicación practica de la invención, por diferentes motivos, a veces es preciso movilizar el canapé de una cama, bien ya sea para llevar a cabo la limpieza del suelo, o por otros motivos que no vienen al caso, de manera que, la cama debe levantarse a pulso, con el consecuente riesgo de daño para la espalda del usuario. In the practical scope of the invention, for different reasons, it is sometimes necessary to mobilize the bed couch, either to carry out the floor cleaning, or for other reasons that are not relevant, so that , the bed must be raised freehand, with the consequent risk of damage to the user's back.

Tratando de obviar esta problemática, son conocidos mecanismos a base de ruedas, que en situación inoperante dichas ruedas permanecen escamoteadas, en orden a impedir que la cama se desplace accidentalmente, mientras que accionando un mecanismo, las ruedas emergen, facilitando el desplazamiento del canapé. Trying to obviate this problem, wheels-based mechanisms are known, which in an inoperative situation said wheels remain retracted, in order to prevent the bed from accidentally moving, while actuating a mechanism, the wheels emerge, facilitating the movement of the couch.

El problema que presentan este tipo de mecanismos, es que el acceso al mecanismo de accionamiento de los mismos es complicado, al situarse en el interior del canapé, a lo que hay que añadir la brusquedad que supone el escamoteo de las ruedas, debido al peso de la propia cama, ya que estos no disponen de medios de amortiguación para las ruedas. The problem presented by this type of mechanism is that access to the drive mechanism is complicated, as it is located inside the couch, to which we must add the roughness of the wheel slapping, due to the weight of the bed itself, since these do not have damping means for the wheels.

Esta problemática se da igualmente en el ámbito de las camas nido. This problem also occurs in the field of nest beds.

DESCRIPTION OF THE INVENTION

El dispositivo de manipulación que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, asegurando una perfecta estabilidad de la cama en cualquier posición seleccionada para la misma. The manipulation device that the invention proposes solves in a fully satisfactory manner the above-mentioned problem, ensuring a perfect stability of the bed in any position selected for it.

Para ello y de forma mas concreta, se ha previsto que la cama, carezca de ruedas en sus vértices anteriores, donde dispone de patas que cuando apoyan sobre el suelo impiden que la cama pueda moverse de forma aleatoria, con la particularidad de incorporar no obstante a nivel medio de su zona frontal una rueda verticalmente desplazable, de manera que cuando dicha rueda adopta una posición límite inferior la cama se levanta ligeramente, separándose sus patas anteriores del suelo y permitiendo una plena libertad de movimiento, mientras que cuando dicha rueda se retrae y adopta una posición limite superior, entonces la cama descansa sobre el suelo a través de las citadas patas, con lo que queda inmovilizada. For this and more specifically, it is expected that the bed, lacks wheels in its previous vertices, where it has legs that when they rest on the ground prevent the bed from moving randomly, with the particularity of incorporating however at the middle level of its frontal area a vertically movable wheel, so that when said wheel adopts a lower limit position the bed rises slightly, separating its front legs from the ground and allowing full freedom of movement, while when said wheel retracts and adopts an upper limit position, then the bed rests on the floor through the aforementioned legs, which is immobilized.

Para ello la rueda está montada sobre el bastidor de la cama con carácter retráctil en sentido ascendente en contra de la tensión de un muelle, de manera que dicho muelle tiende a que dicha rueda adopte en todo momento la situación limite inferior para la misma, pero estableciéndose entre la rueda y el complementario soporte una leva accionada por una maneta, de forma que la basculación de dicha maneta trae consigo un giro del soporte de la rueda con respecto a la citada leva, y consecuentemente el bloqueo o desbloqueo de la misma. For this, the wheel is mounted on the bed frame with a retractable upward direction against the tension of a spring, so that said spring tends to have said wheel adopt the lower limit situation at all times, but being established between the wheel and the complementary support a cam driven by a lever, so that the tilting of said lever brings about a rotation of the wheel support with respect to said cam, and consequently the blocking or unlocking thereof.

La citada maneta actúa además como asidero que al proyectarse frontalmente con respecto al bastidor de la cama, facilita la manipulación de dicha cama inferior. Said handle also acts as a handle which, when projected frontally with respect to the bed frame, facilitates the manipulation of said lower bed.

PREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas puede observarse como el dispositivo que la invención propone, que como anteriormente se ha dicho está destinado a fijarse en la zona media del larguero (16) anterior de la cama, está constituido a partir de una placa (1), con tetones perforados (2) para su correcto posicionamiento y fijación al citado larguero de la cama, no representado, preferentemente con la colaboración de una chapa o protector superior (3), que a su vez quedará posicionado superiormente con respecto a tal larguero, incorporando dicha placa (1) un casquillo superior cilíndrico (4), que se cierra por su extremidad superior mediante una tapa (5) fijable con la colaboración de tornillos (6), alojándose en dicho casquillo (4) un resorte (7) que tiende permanentemente a proyectar hacia abajo a un disco (8), que juega en el interior del casquillo (4) de forma similar a un pistón y que cuenta inferiormente con un vástago In view of the aforementioned figures, it can be seen how the device proposed by the invention, which as mentioned above, is intended to be fixed in the middle area of the front beam (16) of the bed, is constituted from a plate (1 ), with perforated lugs (2) for its correct positioning and fixation to the mentioned bed stringer, not represented, preferably with the collaboration of a sheet or upper protector (3), which in turn will be positioned superiorly with respect to such stringer , said plate (1) incorporating a cylindrical upper bushing (4), which is closed at its upper end by means of a cover (5) that can be fixed with the collaboration of screws (6), said spring (7) being housed in said bushing (4). which permanently tends to project down to a disk (8), which plays inside the bushing (4) similar to a piston and which has a rod below

(9) que atraviesa la placa (1) y al que es solidaria una rueda (10), preferentemente de tipo auto-orientable. (9) which crosses the plate (1) and to which a wheel (10), preferably self-orientating type, is integral.

Inmediatamente por debajo del eje (9) soporte de la rueda (10) y con la colaboración de una contratuerca (11), se sitúa un brazo diametral (12) prolongado en una maneta (13) de accionamiento manual, a la vez que entre la placa base (1) y el brazo (12) se establece una leva (14), materializada en un cilindro provisto de una ranura diagonal o canal, capaz de recibir a dicho brazo (12), cuando brazo y placa (1) son paralelos, pero que bloquea el brazo en situación limite inferior para la rueda (10) cuando la maneta (13) bascula 90º y se sitúa perpendicularmente con respecto al canal de la leva (14). Immediately below the axle (9) wheel support (10) and with the collaboration of a locknut (11), a prolonged diametral arm (12) is placed on a manually operated handle (13), while entering the base plate (1) and the arm (12) a cam (14) is established, materialized in a cylinder provided with a diagonal groove or channel, capable of receiving said arm (12), when arm and plate (1) are parallel, but blocking the arm in a lower limit situation for the wheel (10) when the handle (13) tilts 90º and is positioned perpendicularly with respect to the cam channel (14).

De acuerdo con esta estructuración, el funcionamiento del dispositivo es el siguiente: According to this structuring, the operation of the device is as follows:

En posición operante del mismo, la mostrada en las figuras 1 y 3, la maneta se sitúa paralelamente al larguero anterior de la cama, quedando sensiblemente escamoteada, y el brazo (12) de dicha maneta queda enfrentado a la acanaladura de la leva (14), de manera que el propio peso de la cama obliga a la rueda (10) a retraerse en contra del muelle (7), quedando la cama apoyada sobre el suelo a través de las patas anteriores de ese bastidor, con lo que dicha situación resulta estable. In its operative position, the one shown in figures 1 and 3, the handle is placed parallel to the front beam of the bed, being substantially retracted, and the arm (12) of said handle is facing the groove of the cam (14 ), so that the weight of the bed itself forces the wheel (10) to retract against the spring (7), with the bed resting on the floor through the front legs of that frame, so that this situation It is stable.

Cuando se desea extraer la cama, basta con hacer bascular 90º la maneta (13) para que el brazo (12) se encuentre con el plano inclinado (15) de la leva (14) y la cama se vea obligada a ascender, de manera que sus patas anteriores pierdan el apoyo sobre el suelo, quedando cargada dicha cama a nivel anterior sobre la rueda (10), posición en la que la maneta (13) se proyecta frontalmente hacia delante, tal como muestra la figura 2, actuando como asidero que permite el arrastre de la cama hasta cualquier punto deseado para la misma. When it is desired to remove the bed, it is enough to tilt the handle (13) by tilting the arm (12) with the inclined plane (15) of the cam (14) and the bed being forced to ascend, so that its anterior legs lose their support on the ground, said bed being loaded at the previous level on the wheel (10), position in which the handle (13) is projected frontally forward, as shown in Figure 2, acting as a handle which allows the drag of the bed to any desired point for it.

Tras seleccionar el nuevo posicionamiento de la cama, basta con bascular nuevamente la maneta (13) en sentido contrario, para que la leva (14) deje de retener al brazo (12) que pasa a quedar enfrentado a la acanaladura de la leva (14), con lo que la cama desciende por su propio peso, a la vez que la rueda (10) se retrae en contra de la tensión del muelle (7), quedando la cama apoyada sobre el suelo a través de sus patas anteriores y, consecuentemente, en una posición perfectamente estable. After selecting the new positioning of the bed, it is enough to tilt the handle (13) in the opposite direction again, so that the cam (14) stops retaining the arm (12) that happens to be facing the groove of the cam (14 ), so that the bed descends by its own weight, while the wheel (10) retracts against the tension of the spring (7), leaving the bed resting on the floor through its front legs and, consequently, in a perfectly stable position.

De acuerdo con una variante de realización, la mostrada en la figura 5, el vástago (9) puede prolongarse superiormente en un tramo (9’) que se remata redondeadamente, de manera que la tapa (5’) presentará una especial configuración, concretamente incorporará un cuello tubular (17) centrado, de menor altura que el casquillo (4), determinante de un orificio cilíndrico (18), formal y dimensionalmente adecuado para recibir en su seno al tramo (9’) del vástago (9), de manera que este cuello tubular (17) actué como elemento de guiado en el desplazamiento vertical del vástago (9), en contra de la tensión del resorte o muelle (7), asegurando la verticalidad del mismo, y consiguiendo con ello una perfecta estabilidad en dicha maniobra, que se traduce en una mayor suavidad de movimientos. According to a variant embodiment, the one shown in Figure 5, the rod (9) can be extended superiorly in a section (9 ') that is rounded off, so that the cover (5') will have a special configuration, specifically it will incorporate a centered tubular neck (17), of a lower height than the bushing (4), which determines a cylindrical orifice (18), formally and dimensionally suitable to receive in its bosom the section (9 ') of the rod (9), of so that this tubular neck (17) acts as a guiding element in the vertical displacement of the rod (9), against the tension of the spring or spring (7), ensuring its verticality, and thus achieving perfect stability in This maneuver, which translates into greater smoothness of movement.
