Definitions

  • the invention relates to a piece of furniture, in particular for the care and / or medical field, with an electromotive drive for adjusting one or more connected furniture parts and with at least one power supply cable with at least two wires.
  • the furniture in question is especially designed for nursing homes or hospitals, but can also be used in the private sector.
  • the electric motor drive including the power supply cables are supplied to a furniture manufacturer by the drive manufacturer as a subcontractor.
  • the furniture manufacturer must ensure proper installation, especially of the electrical cables.
  • the electrical cables are firmly installed within the furniture.
  • a strain relief for the cable is provided immediately before the connection of the power supply cable to the connection of the electric motor drive, so that the connections are not stressed. Since it often happens that, particularly in nursing homes, the furniture, preferably the bed, is moved in an impermissible manner by pulling the power supply cable, a further strain relief is provided in the edge region of the bed.
  • a coupling consisting of a socket and a plug is provided in this edge region, which would be separated when the cable was pulled.
  • the invention is based on the object of designing a piece of furniture of the type described in the introduction in such a way that the already extremely high level of security in the case of such furniture or electromotive drives is increased still further, and that in the event of damage to the furniture from the voltage source leading part of the power supply cable, the exchange is much easier.
  • a safety housing is fixed on a stationary component of the furniture and / or on the electromotive drive, and that the power supply cable leading to the electromotive drive is electrically conductively connected within the safety housing to a supply cable leading to the voltage source.
  • the safety housing divides the power cable into the power supply cable leading from the safety housing to the electric motor drive and into the supply cable leading from the voltage source to the safety housing. It can be assumed that the manufacturer of the furniture assembles the safety housing according to the regulations on a stationary component. If the supply cable lying outside the furniture is now damaged, only this cable has to be replaced. This is particularly simple since the security housing is expediently installed in the edge region of a piece of furniture, so that it is particularly easily accessible. Even if, for example, a bed is now moved by pulling on the supply cable, a separation would take place within the safety housing, so that the user does not have to work on the power supply cable or on the electric motor drive.
  • Security is further increased by arranging two screwed cable glands on the safety housing, the supply cable being fed through one screwed cable gland and the power supply cable through the other screwed cable gland.
  • the cable glands on the sides facing away from the safety housing are each equipped with a flexible anti-kink element, which can be designed, for example, in a spiral shape and forms an integral molded part with the cable glands.
  • the safety housing So that the safety housing is accessible, it is closed by a removable cover.
  • the cover is fixed in such a way that it can only be removed from the safety housing with a suitable tool, if necessary even with a special tool. This is to prevent, for example, sick or people in need of care from removing the cover.
  • a circumferential seal is expediently used so that the components located in the safety housing are adequately protected against moisture and the like.
  • at least two screw channels are provided in the walls of the security housing which are perpendicular to the lid and which are covered by the attached lid. It is then only possible to remove the safety housing from the component if the cover has been removed beforehand.
  • the fuse While in the previously known drives the fuse is located inside the housing or a closed chamber of the electric motor drive, so that the drive needs to be removed to change the fuse, the fuse can now be changed by opening the safety housing. As a result, the furniture can be adjusted again in a very short time by means of the electric motor drive.
  • the end of the supply cable facing away from the safety housing is equipped with a plug with at least two contact pins.
  • at least one fuse is installed in the plug. This can prevent the fuse in the safety housing and / or in the electric motor drive from responding if the supply cable is damaged. So that damage can be prevented, it is provided, for example, that the supply cable leading from the voltage source to the safety housing is provided on the outside with a coating or coloring in a luminous color.
  • a further embodiment provides that a switch is installed in the safety housing and / or in the power plug. In this case, for example, the electric motor drive could not be put into operation during periods of rest or at night.
  • This switch is in a particularly advantageous manner an automatically operating switch in the form that the power supply can be rebuilt when an operating button is pressed, so that the power supply is interrupted by a plurality of operating buttons when the operating button or the last operating button is released.
  • the connection to the power supply is opened by this remote control, which is analogously remote.
  • the automatically operating switch can be, for example, an electromechanical relay or a semiconductor switch. The great advantage is that the mains voltage no longer reaches the drive during long breaks in operation.
  • FIG. 1 shows the supply cable and the power supply cable with the interposed safety housing of the furniture according to the invention in a view.
  • the furniture is not shown.
  • This furniture is preferably a nursing bed or a hospital bed.
  • the supply cable 1, which can be connected to a voltage source, for example to a socket, a rechargeable battery or a battery, is guided into a safety housing 2, to which the power supply cable 3 leading to the electromotive drive is also connected.
  • a cable gland 7 is attached to each of two opposite sides.
  • Each cable gland 7 is followed by an anti-kink element 4 which, for example, can be integral with the cable gland 7.
  • the kink protection element 4 is flexible or elastic.
  • the free end of the supply cable 1 is equipped with a straight contour plug, which has two contact pins and is also equipped with a fuse 5.
  • the supply cable 1 is connected to the power supply cable 3 by clamping in a generally known form. At least one of the clamps inside the safety housing 2 is equipped with a fuse clamp. In addition, each end region of the supply cable 1 and the power supply cable 3 is equipped with a strain relief. Contrary to the illustration according to FIG. 1, the supply cable 1 lying outside the piece of furniture can be wound up in a spiral or a protective tube can be pulled over it.
  • the invention is not restricted to the exemplary embodiment shown. It is essential that the supply cable 1 and the power supply cable 3 are connected to one another in an electrically conductive manner within a security housing 2 that is permanently installed on a furniture component.

Abstract

La présente invention concerne un meuble utilisé de préférence dans le domaine des soins et/ou de la médecine, comportant un entraînement par moteur électrique servant au déplacement d'une ou de plusieurs parties de meubles, et comprenant un câble servant à l'alimentation électrique, ledit câble présentant au moins deux conducteurs. L'invention a pour objet d'améliorer la sécurité qui est déjà élevée pour des meubles de ce type dotés d'entraînements par moteur électrique, de faciliter sensiblement le remplacement en cas de détérioration de la partie du câble d'alimentation électrique, menant du meuble à la source de tension, ainsi que de garantir de manière simple que des meubles déjà livrés, équipés d'un entraînement par moteur électrique, peuvent être rééquipés. Selon l'invention, un boîtier de sécurité est fixé à une partie fixe du meuble et/ou à l'entraînement par moteur électrique. A l'intérieur de ce boîtier, le câble d'alimentation électrique (3) menant à l'entraînement par moteur électrique est connecté à un câble d'alimentation (1) menant à la source de tension. De préférence, deux fixations par vis (7) sont fixées au boîtier (2), lesdites fixations étant chacune associée à un élément anti-coudage flexible (4). Cet élément anti-coudage (4) a une forme spiralée et forme une seule pièce avec la fixation par vis (7). Le meuble de l'invention est de préférence un lit de malade ou de soins.
