Description

State of the art:

at movable furniture parts, for example, in movable in a furniture carcass furniture drawers Arrangements are known which comprise a light source to a To achieve lighting in or on the movable furniture part.

Object and advantages of the invention:

task The invention is novel light effects with light from a light source on a movable furniture part technically advantageous to achieve.

These Task is by the claims 1 and 10 solved. In the dependent claims Advantageous developments of the invention are shown.

First off you go the invention of a device for generating a lighting effect on a movable relative to a fixed furniture part furniture part with a light source, wherein the light source on the movable furniture part can be arranged. An essential aspect of the invention is that Coupling means are provided to a mechanical connection allow the device to the movable furniture part and light from the light source into a translucent wall portion of the movable furniture part couple. This can be used for movable furniture parts with a translucent, translucent or transparent wall section desired light effects on the movable furniture part achieve.

Especially This is advantageous in drawers or extracts, which a comparatively large Storage height to disposal put, z. B. with front heights of about 0.3 meters and more. In such movable furniture parts for example, are used by default Drawer or pull-out frames for excerpts with usual Storage height used, which in addition provided with an increase become. With the increase the drawer is provided with a section that functions a wall of the furniture part Fulfills. With this increase or the upwardly extended wall section can be placed in the drawer content against a lateral Protected from falling out or supported become. As a rule, the drawer frames are made of metal, plastic or wood. The type or material of the increase may differ from the relevant Differentiate drawer frames. The increase is in particular a separate one prefabricated part and can easily on a certain desired lighting effect be designed targeted, z. B. be at least partially translucent, so that light can be coupled effectively. With the appropriately enlightened increase can an excerpt or a drawer especially on both sides with an impressive luminosity be provided, what the valence the drawer under aesthetic Can significantly increase points of view.

About the Ankoppelmittel can also the device for generating the lighting effect stable or protected on the movable furniture part attached or attached. The coupling means are in particular designed so that the light source at different attachment points or in selectable Alignment is definable. Also, it can be an afterthought Replacement of the light source easily done.

in principle are different coupling possibilities the light possible, in particular, from different sides of the translucent wall section Light can be coupled. Optionally, one or more of several places light from one or more light source (s) in the translucent Wandungsabschnitt be coupled. In particular, light of two opposite Edge regions coupled into the respective translucent wall section become. The coupling agents can on existing sections on the movable furniture part be formed so that no additional elements are needed or can partly by additional on the movable furniture part be realized parts to be realized. The coupling means are in particular not or little noticeable on the movable furniture part integrated, in particular so that the light source and the device does not appear to produce the light effect. The relevant parts can z. B. housed in wells or covered.

The translucent wall portion of the movable furniture part can in principle be arbitrarily positioned or oriented, for. B. belong to a front part, side part, bottom part and / or back part of the movable furniture part. In this case, the translucent wall section and only partially z. B. semitransparent. The translucent wall portion may also be wholly or partially reflective over portions of light radiating out of the wall portion toward the outside or from the outside towards the interior of the wall portion. In addition, it is conceivable that the translucent wall portion is partially designed differently with respect to the light transmission behavior. For example, one side of the wall portion may be translucent and another side of the same wall portion may not be translucent. So z. B. radiate the movable furniture part only inward or outward light. Also, a radiation of light in a first region of the translucent Wan outside section and at the same time a radiation of light in a second region of the translucent wall portion inward is possible according to the invention.

Under Light is electromagnetic waves from the entire electromagnetic wave spectrum too understand, especially in a selectable or predetermined wavelength range. In particular, light is understood to mean a wavelength range whose electromagnetic waves for the human eye are perceptible.

advantageously, the coupling means are adapted to a connecting element of two converging, in particular angled converging Wall sections of the movable furniture part to form. To this Way you can the coupling means inconspicuous or without necessary additional Space on the movable furniture part be designed. Because for the stable attachment of the translucent wall section can a connecting element z. B. between a rear wall of movable furniture part and the translucent Turning section be required anyway, then used can be to realize the Ankoppelmittel or the light source including the supply line. The connecting elements can, for example End connections of two or more than two converging ones Be wall parts of the movable furniture part. For example, drawers can the connecting elements corner post in the area between a drawer side wall and a drawer back wall, or front connector in the area between a drawer side wall and a drawer front.

It It is further proposed that the device has a translucent wall section includes, in which light can be coupled and which an existing portion of the movable furniture part as a wall section can be arranged. So can movable furniture parts without translucent Wandungsabschnitt be provided with such a light in this to couple or the desired To achieve lighting effect. It is possible that the translucent wall section can be arranged above existing side walls or the translucent Wandungsabschnitt alone a side wall of the movable furniture part forms.

Prefers is the translucent Wall section formed with light-conducting properties. For example, it can be over the translucent Wandungsabschnitt light at one point coupled via coupling surfaces and the light is passed on to different places be where it's over outcoupling the translucent Wandungsabschnittes can escape again. The light pipe can inside the photoconductive element via total reflection or partial light reflection or partial light transmission respectively. Direction and intensity the exiting light and thus the light effect generated essentially by the light source or the embodiment of the translucent Wall section determined.

Of the translucent Wall section consists in particular of a silicate glass material and / or a polymeric material. With these materials, the translucent wall sections particularly stable or resistant and with an aesthetic sophisticated appearance. Also suitable These materials for light transmission or Lichtein- and Light extraction.

In a further advantageous embodiment of the subject invention is the translucent Wandungsabschnitt configured, in a drawer in a side Area between a front part of the drawer and a rearward part the drawers to be arranged. This area can be at high Drawers or extracts through appropriate additional Wall sections can be easily increased. Usually are Rear areas or front areas of the drawer higher than drawer, thereby an increase only the page areas is necessary.

Of the translucent Wandungsabschnitt is preferably plate-like. This is in view on the production of the Wandungsabschnitts and its attachment advantageous to existing portions of the movable furniture part.

Further It is suggested that a power supply for the light source and switching means to close and interrupting the power supply are present. So that can the light source will be powered, with an interruption the power supply optional is. With that you can desired Light effects, for example, only at certain times or in certain predetermined movement phases of the movable furniture part occur.

It is further proposed that the switching means are designed to switch the power supply of the light source depending on a movement state and / or a position of the movable furniture part. Thus, individually adapted to the lighting effect on the movable furniture part can be realized. In particular, in drawers with a translucent wall portion of this so with Light of the at least one light source are acted upon, that when removing the drawer, an indirect light is generated, for. B. is illuminated brightly inside, especially even milky white or colored. Thus, a diffuse light radiation can be generated, which can trigger a pleasant mood or effect in the viewer. The light effect is in particular tuned so that no illumination or active irradiation of the interior of the drawer takes place.

The Invention also relates a furniture part, which is movable relative to a stationary furniture part, in particular Drawer, being on the furniture part a device according to the above-explained Embodiment exists. This can be the advantages mentioned also for a corresponding furniture part realize.

Prefers is for receiving an end portion of a wall portion of movable furniture part a receiving element provided, in which integrates the light source is, in particular with power supply and switching means. Leave it z. B. subsequently Space-saving attachable or existing areas on the movable Furniture part or a wall portion of the movable furniture part for integrating the Use light source and the power supply with switching means. In order to is also an afterthought Attachment of the device for generating the light effect with light source, power supply and switching means readily possible.

Further It is proposed that the coupling means at one end a translucent Wall section adjacent to light in the wall section couple. The Ankoppelmittel can z. B. a corner connector, Corner post or an intermediate piece be what is in a corner area between the back wall and side area of the movable furniture part is positioned. In this part, the light source is advantageous storable, especially not visible or hidden, to light in the translucent Einkoppeln Wandungsabschnitt.

Further It is proposed that the translucent wall section itself in the rear area of the movable furniture part located. So can a rear wall section of the movable furniture part be supplied with light to produce a desired lighting effect there. This is preferred insofar as this part of the movable furniture part usually surrounded or partly covered by furniture carcase sections, so that less light from the outside the rear wall section can reach. Optionally, in a corner element of the furniture part both a light source for Lichteinkopplung in the rear translucent area as well as a light source for light coupling into the translucent side wall portion to get integrated.

Finally located in an advantageous embodiment of the subject invention the translucent Wall section in the front region of the movable furniture part. Thus, the optically particularly formative part of the movable furniture part, because both in the open as also visible in the closed state, advantageously illuminated or enlightened become.
