Description

The present invention relates to transparent casings, at least in sections, such as showcases or aquariums, with an electrical consumer that is on top of the device is arranged. Such electrical consumers can Case of showcases, for example lamps, sensors, such as temperature or humidity sensors or sensors from alarm systems or mini speakers, and in the case of aquariums, for example, illuminants, automatic feeders, Pumps, sensors or similar his.

The invention and the underlying problem is shown below using the example of showcases, especially all-glass showcases, discussed, but it is not limited to showcases. Showcases usually contain several disc-shaped Wall elements in their edge areas along connecting lines together are. At least one or more of the wall elements are transparent, to give an insight into the showcase.

Showcases in the ceiling area with ceiling lighting on a lamp whose supply with electric current over Lines are made from the bottom of the showcase up through the showcase respectively are. The showcases on the market with ceiling lighting receive the power supply via visible cables, via conductive angle rails, with which the wall elements are connected, or metal rods or Wire systems that all give a technical impression and such a desired one neutrality and reluctance with an elegant, high-quality all-glass showcase, for example made of white glass let miss. equally the signal line of an alarm sensor should be routed unobtrusively.

It is therefore the object of the present invention a housing to provide with electrical lines, in which the disruptive influences by Lines reduced or completely is avoided.

The task is solved by the housing according to the independent protection claim 1.

The housing according to the invention comprises at least one transparent Plate element and at least one electrical conductor, the at least one transparent plate element has a recess, their longitudinal direction extends essentially parallel to a main surface of the plate element, and wherein the electrical conductor at least in sections in the Recess runs.

In a further development of the invention includes that housing according to the invention at least a first transparent plate element and a second plate element, wherein the first plate element with an edge surface along a connecting line against an edge surface or a main area of the second plate element; and an electrical conductor which has at least one section which runs essentially parallel to the connecting line characterized that the first plate element has the recess along the edge surface, in which the at least a portion of the electrical conductor runs.

A plate element in the sense of the invention is essentially a body by two essentially parallel, for example plane-parallel, trending main areas and through several edge surfaces limited, the marginal surfaces the main areas limit and connect them together. The distance between the main surfaces is much less than the extension of the body in the Level of the main surfaces. The main areas can for example polygons, such as rectangles, trapezoids, parallelograms, Triangles, pentagons, Hexagons, etc. his.

In addition to plane-parallel main areas, the Plate elements also in one dimension or at least in sections arched in two dimensions his. Essentially parallel means that the main surfaces in limited sections can not be performed in parallel, for example, a magnifying lens to be realized in a transparent plate element.

A transparent plate element comprises as a material, for example glass, sapphire, or an organic Material such as plexiglass or similar

The housing can have a footprint for example any regular or irregular polygonal Have geometry, currently rectangles or squares, trapezoids, Parallelograms, triangles, pentagons, Hexagons or octagons are preferred. On the other hand, the base can also sections of arcs, include a full circle, an ellipse, or other curved lines. As side walls serving plate elements are each azimuth corresponding to one Section of the footprint aligned.

With a housing with a rectangular base, the Plate elements, for example the side walls, a front wall, a Back wall, the Bottom or a lid.

The plate elements can go along joined the connecting line, for example glued, or they can be held by other means be fixed in position to each other.

The electrical conductor comprises, for example, a metallic wire or rod with a round, semicircular or polygonal cross-section, the maximum cross-sectional diameter preferably being less than the distance between the main surfaces of a plate element. The electrical conductor comprises, for example, an uncoated, high-gloss nickel-plated or silver-plated brass wire or rod, for example not more than 1.5 mm in diameter, or high-gloss nickel-plated, high-gloss silver-plated copper wires or rods with a diameter of, for example, 0.8 mm or more, depending on the power requirement. Possibly. Multi-core cables can also be used with one, wherein the outer surface of the insulation material of the cable can also be provided with a reflective layer. Likewise, coloring the insulation material or the conductor surface should be considered if tinted transparent plate elements are used. For example, a continuous wire can be used as the conductor, or different sections of wires or rods can be used which are galvanically coupled to one another in a suitable manner. This can be done, for example, by soldering, welding, or connecting with a clamp or by a plug-in process.

The recess along the edge surface can have any shape, for example, a groove or groove can be guided in the edge surface, which is suitable for receiving the electrical conductor, or the recess can comprise a chamfer, which is located in the transition region between one of the edge surface and a main surface of the extends first plate member. The chamfer can be made planar at an angle of, for example, 45 ° to the edge surface and to the main surface, or the chamfer can have a fillet or an angle profile. The configuration of the cutout as a chamfer is advantageous in that a chamfer can be implemented inexpensively.
Possibly. a conductor can be used, the cross-sectional area of which is adapted to the shape of the recess, so that the conductor makes optimum use of the space in the recess.

The electrical conductor is preferred thus guided in the recess, that the Cross section of the electrical conductor is not above the level of through the Main area affected by chamfer protrudes.

According to another embodiment the recess can also be in a main surface of a Plate element run. In this case, the recess can, for example include a groove. Such an embodiment can, for example in a serving as a cover of a housing Plate element can be used, the recess e.g. in a central area of the main surface, for example to the center, guided is.

According to a further embodiment the invention can be a lid or other wall element housing also have two coplanar plate elements, a first edge surface of the first plate element against a second edge surface of the second plate element abuts, and being at least the first edge surfaces has a recess, for example a chamfer.

The housing according to the invention can have several electrical ones Have conductors according to the previous described type led are. You can do this, for example several edge areas, each against a main surface or hit another edge surface, one Have recess, in each of which an electrical conductor is guided. Similarly, several conductors can be routed in one recess.

Of course, the various configurations of the cutouts according to the invention can be combined with one another as desired.
Insofar as the glass parts of a housing, such as the rear wall, side walls, lids and floors, usually have chamfers on all edges, which have the effect that the refraction effects of the glass, in particular the white glass, are enhanced, particularly when illuminated, a high-gloss wire inserted in wide chamfers is also not immediately distinguishable or recognizable from the glass due to their own light reflections. Taking advantage of the materials is one aspect of the invention. For glasses that are sandblasted, etched or satinized or screen-printed, matt nickel-plated wire is recommended. In the case of colored or lacquered glass, the wire or rod can be colored or colored accordingly.

With this type of power supply inside or outside a showcase through whichever parts and use of minimal illuminant will be a big one Problem of optics and aesthetics solved and as a result, essential further development of the know-how and the technology also achieved an increase in value.

The invention is now based on the Exemplary embodiments illustrated in the figures. It shows:

1 : A detailed perspective view of a first embodiment of the invention;

2 : A detailed perspective view of a second embodiment of the invention;

3a . b : a supervision of variants of a third embodiment of the invention;

4a-c : Overview of sectional views through different cut-out options.

In the 1 showcase shown in the cutouts is an example of a housing according to the invention. The showcase has a rectangular base with a base plate, which can optionally be made of glass, and four vertically arranged glass plates as walls, of which only one side wall in the drawing 1 and a back wall 2 are shown, the side wall 1 with a first edge surface against the rear wall 2 encounters. There is a glass lid on the upper edge of the glass plates 4 on the first plate-shaped lid half 4a and a second plate-shaped cover half 4b comprises, wherein the cover halves are arranged coplanar and abut against one another with their edge surfaces.

In this exemplary embodiment, the cutouts for guiding electrical lines are formed by chamfers. For this purpose, for example, the first edge surface of the side wall 1 as a recess in the showcase interior edge used a first chamfer that is sufficiently deep that a rod-shaped metallic conductor 5 can be performed in it. The cross section of the conductor preferably projects 5 not over the inner major surface of the side wall 1 inside the showcase.

Correspondingly, on the inner edge of the upper edge surface of the side wall 1 a second chamfer is provided in which a second rod-shaped metallic conductor is guided forward to the center of the side wall. The chamfer and the second conductor extend at least up to the connecting line between the two cover halves 4a and 4b , At least one of the edge surfaces of the cover halves has a chamfer on the lower edge along the connecting line in which a third metallic conductor 7a is guided, with the third metallic conductor 7a extends to a socket for a lamp on the underside of the lid in a central area of the lid. If a lamp with a large amount of heat, for example a halogen lamp, is provided, it may be expedient to provide a hole through the cover in order to allow the heat to escape. If LEDs are used, there is no need for a hole. The second wire for feeding the light source is routed analogously via chamfers in the edge surfaces of a second side wall, not shown here.

For connecting the showcase to a power supply are in the base plate with the vertically running conductors aligned holes provided through which the conductors from the Showcase led out and suitably to a supply source, for example a low voltage source.

For example, a rod-shaped conductor cannot sheathed silver-plated or high-gloss nickel-plated brass wires or copper wires of at most 1.5 mm or, if appropriate, also thinner wires or other inconspicuous, the Glass character adapted for materials suitable for sufficient flow of low-voltage current, be used.

The conductors can have any cross section have, for example, rectangular or circular or semicircular can be. Possibly. the cross-sectional shape of the conductor can be the shape of the recesses customized his. Insofar as the recess in this embodiment a chamfer of, for example, 45 ° would be a more suitable one Conductor cross section a right-angled isosceles triangle, so that the Head fills the recess optimally. The wires can, for example, be glued, et al UV glue on one plate or, if necessary, on both plates adjacent to it be attached. To guarantee a reliable galvanic coupling between the individual sections of the power line, So the first, second and third conductors are the adjacent ones Ladder, by spot welding or spot soldering connected with each other.

In the 2 Showcase shown essentially corresponds to the showcase 1 , however, it differs from this as follows. The lid 14 comprises a one-piece glass plate. Through the lid 14 is a vertical hole 11 guided, which is aligned with a chamfer-shaped recess which is formed on a side wall on the inner edge of the edge surface thereof, the side wall abutting the rear wall with the edge surface. There is a first rod-shaped conductor in the recess 15 led out through the hole 11 to the top of the lid 14 extends. From the hole 11 extends a first milled groove 12 in the top of the lid 14 to about a center line perpendicular to the first groove, the first groove 12 preferably parallel to under the first groove 12 extending side wall. The lid has a second groove along the middle line 13 on, the first groove 12 in the second groove 13 flows out, and the second groove 13 up to a hole 18 extends in which the socket for a lamp is arranged. In the first first groove 13 is a second leader 16 and the second groove 13 a third leader 17 guided, the conductors being galvanically connected to one another as before. The second wire of the power supply is analogous to the other side of the showcase.

Insofar as the grooves are very complex to manufacture, one or both grooves with a conductor guided therein can be dispensed with for cost reasons. Instead, you can use flat brass strips or copper strips, which are as inconspicuous in size as possible and are sufficiently strong in the passage of current, as a connection between the rear rising conductor 15 and the bulb holder in the hole 18 or the third leader 17 on the lid 14 lead and attach for example by gluing.

If, in a different construction of the showcase, the two side walls are not butt-glued to the rear wall, but rather the rear wall and possibly also the glass cover plate between the side walls, then there are further options for guiding the supply lines and the necessary cutouts, as shown in FIG 3a and 3b to be explained.

The chamfers 23 . 33 to accommodate the vertical ladder 25 . 35 can namely both inside 33 as well as outside 23 right and left on the back wall 22 . 32 the showcase without having to drill holes for the ladder.

At the in 3b shown internal power supply runs a first conductor 35 inside over a chamfer 33 on the inner edge of the side edge surface of the rear wall 32 up from the display case floor, then over a bevel 37 on the lower edge of the side edge surface of the inner cover to the front up to about the middle of the edge surface, then in a recess on the underside of the cover up to a lamp 38 in the middle of the lid. The recess on the underside of the cover can be formed either by one or two chamfers on the connecting line between two cover halves or by a milled groove in a one-piece cover plate. If the illuminant comprises LED or cold light, this is a particularly simple and recommended way, since no heat build-up occurs and no ceiling hole is required. With halogen, the heat development must be taken into account, which can loosen a wire glued on the inside if it is too close. A hole may have to be drilled in the glass cover here.

If the power is only to be supplied externally, then as in 3a shown chamfering 23 . 27 on the back wall 22 outside and in between the side walls 21 inserted glass lid 24 attached on the top left and right. For the way to the lamp 28 In the middle of the lid there is a recess on the top of the lid, which, as before, can comprise a milled groove or a chamfer on the connecting line between two lid halves.

4a to c show an overview of some of the cutouts.

In 4a is a cross section through the lid 4 out 1 shown. A cover half has a chamfer on the lower edge of an edge surface, in which the conductor 7a is led.

In 4b , is a cover variant of the embodiment 3b shown in the ship. Both halves of the lid 34a . 34b have a chamfer on the lower edge of the abutting edge surfaces. This creates a larger recess in which the conductor is guided.

Finally shows 4c the variant 2 with a groove 13 in the top of the lid or the upper main surface of the lid 14 ,

For showcases where you have sections or completely want to do without holes, chamfer cuts and groove milling one instead of the wires only those already mentioned Metal strips. They are glued in the area of the rear wall / side wall connection to the outside the back wall up to the glass lid, and goes up to the middle of the lid to the center of the page and from there at right angles to the filament. So receives a practicable inexpensive and relatively inconspicuous supply line for one Ceiling lighting. Should this inconspicuous narrow streak disturb, one with sandblasting or etching technology a similar attach effective design element.

For the case that the showcase should be free-standing, or instead of with a door provided as a hood shape is completely closed, e.g. on a freestanding Pillar, the showcase and all exhibits are equivalent from all sides and without any optically distracting impairments consider. It has a ceiling lighting, with which the power supply can (almost) no longer recognize. Depending on the application, a Standard halogen lamp or such a greatly reduced socket and Technology cladding is used that almost only the illuminant halogen or LED lighting itself is visible.

To the philosophy of total reduction of To complete lighting are the smallest luminaries for halogen or LED lighting unfortunately not yet available on the market. The Connection of wire to the socket of the lamp and the porcelain socket the halogen lamps and the mostly very small but black or colored ones Socket of the LED lamps should not be visible. You receive as a privacy screen one in the size of the frame and the lamp or according to the design corresponding sleeve as a luminous body. she can Made of stainless steel, aluminum, suitable light metals / sheets or plastic in high-gloss, matt, powder-coated or colored and the like Shapes and design to match the handle, fitting and feet Claim to be made and are made to the continuous or two-part Glass plate glued from below with UV glue or with a magnetic ring held. In the case of a hole, this sleeve is in the glass cover below the recess for the power line so UV-glued in that it does not come into contact with the Gets power line. It can only go so far down that the technology, i.e. connection and socket, is just covered is and therefore the purpose of minimally visible metal processing or lamp holder fulfilled becomes. Depending on the requirements, this can be as small as possible also be designed so that they e.g. through two small tabs or another unremarkable Type of bracket is held on the top of the glass lid and doesn't fall down without having to be glued. In a porcelain socket, the halogen lamp is because of the heat a hole in the glass lid on the porcelain may be important to get one possible heat build-up to prevent. Likewise, with UV gluing the sleeve is a not warm and insert non-current-conducting spacers between the socket and the metal sleeve, to heat the sleeve to avoid.
