Definitions

  • the present invention relates to a recessed in a predetermined liquid, in particular water, candle light, hereinafter abbreviated as underwater candle light, underwater light or simply referred to as candlelight.
  • candlelight for various applications are already known from the prior art, including so-called lanterns, in which the flame of the candle used is protected from extinction by excessive air movements (wind).
  • a candle is generally understood to mean a device which is designed for lighting and, after its lighting, for the permanent emission of light over a predetermined time.
  • it must therefore not be a wax candle or a tea light or the like, but it can also be an oil lamp or the like act.
  • An inventive, in a predetermined liquid (in particular: water, but it may also be another, non-combustible liquid) retractable candle light initially has a float. This is at a first end (hereinafter also referred to as upper end) open, as well as at an upper end opposite end (hereinafter also referred to as the lower end - above and below here refers to the position of the float relative to the earth's surface when beticians- or according to the invention arranging the float in a liquid-filled volume such as in an external vessel) closed.
  • the float can be designed in several parts so that a device -. the weight body described in more detail below - the float is intended to close another component of the float, so that the locked float is buoyant.
  • a hollow portion (light volume) is formed for receiving an external candle.
  • the floating body can be designed in several parts so that first the candle must be introduced into the hollow portion before the several items of the float to the liquid-tight closing of the same are assembled on its underside.
  • At least one gas supply shaft and at least one gas discharge shaft are formed separately, each leading from the hollow portion in the interior of the float to the upper, open end of the float (as described in more detail below, is located in the intended use of the candle light according to the invention this upper End then above the liquid level of the predetermined liquid).
  • Separated from each other here means according to the invention that the gas supply shaft and the gas discharge shaft are at least partially separated from each other fluid-tight, so in particular gas-tight. This can be done by suitable wall guides or appropriately shaped and positioned walls of the two shafts and corresponding Wall materials such as glass, be ensured.
  • the average density ⁇ s of the floating body is less than the average density ⁇ w of the predetermined liquid (especially water). It is preferred that the average density of the unit formed from the float and the candle in their initial state (ie, not yet lit) is less than the average density of the predetermined liquid.
  • the mean density of the floating body here means the sum of the masses of all components of the floating body divided by the volume enclosed by these components.
  • An essential basic idea of the present invention is therefore to use the Archimedean principle with the retractable candle light according to the invention, in particular with its float, ie the weight and volume ratios (ie the density ratios) of the individual components of the float on the one hand and the corresponding density ratios of the predetermined liquid on the other in such a way that the upper end of the sealed floating body remains above the liquid level after immersing it in the predetermined liquid and releasing it.
  • the weight of the external candle should also be taken into account, so the average density of the float, together with the weight of this candle, should be lower than the average density of the liquid.
  • the weight of the candle compared to the weight of the float or its components, negligible.
  • the average density of the float or all parts of the retractable candlelight must therefore be so much smaller than the average density of the liquid that the retractable candle light even with additional initial weight of the candle still bucks enough in the liquid.
  • the weight, volume, shape and density ratios of the individual components of the retractable candlelight or its floating body by suitable shaping and positioning of the individual components (in particular the two tubes and the weight body, see below) designed so that the focus the float preferably already without the inclusion of the external candle at its intended position in the inner, hollow portion of the float (but at least with candle held) in the lower half of the float.
  • This has the advantage that the retractable candlelight can be sunk in the predetermined liquid and (eg even after the entire candle has burnt down) does not tip over and does not fully run (by avoiding the ingress of liquid into the upper, open end of the float) and does not sink below the liquid surface.
  • the mean density of the floating body (preferably including the candle weight) is at least 1%, preferably at least 5%, preferably at least 10%, preferably at least 15%, preferably at least 25% smaller than the average density the predetermined liquid and / or as 1.0 kg / dm 3 (average density of water).
  • the mean density of the floating body is preferably between 0.9 kg / dm 3 and 0.99 kg / dm 3 .
  • the gas discharge shaft (or its light volume), for example by suitable wall guides, within the gas supply shaft (or its clear volume) out.
  • the gas discharge shaft is guided concentrically within the gas supply shaft, wherein the two shafts are preferably formed by one another, in cross-section circular, so cylindrical tubes (or their walls).
  • the gas supply shaft and the gas discharge shaft can basically have any desired cross-sectional shapes. Round pipes, rectangular pipes, triangular pipes, hexagonal pipes or even elliptical or oval pipes as shafts possible. If the two shafts are guided into one another as described above, then the cross-sectional shape of the two shafts does not have to be identical (but is preferably identical).
  • a plurality of gas supply or gas discharge shafts can also be provided.
  • a gas supply shaft within the same distance from each other a plurality of gas discharge ducts are guided.
  • several candles can be positioned below the gas discharge ducts so that in each case an associated candle is arranged below each gas discharge shaft.
  • an associated candle In the middle of each individual candle or its flame can thus be within the same gas supply shaft each one of the respective candle associated gas discharge shaft.
  • several gas supply shafts can each be formed with a plurality of gas discharge shafts arranged therein as described above.
  • asymmetric arrangements of candles within a gas supply shaft or its cross section are also possible.
  • the gas discharge chute need not be concentric within the gas feed chute, but may also be positioned in an asymmetrical arrangement outside the center of the gas feed chute.
  • the float comprises an outer tube whose upper portion (eg over half the length or over two-thirds of the length of the tube) forms an outer wall of the gas supply shaft.
  • the float then further comprises an inner tube (preferably: concentrically guided) guided in this upper region of the outer tube within the outer tube.
  • the inner tube forms over the length of the upper region an inner wall of the gas supply shaft and an outer wall of the gas discharge shaft.
  • the interior of the lower portion of the outer tube (the upper and lower areas correspond to the Total length of the outer tube, so that the length of the lower portion, for example, half the length or one-third of the length of the outer tube corresponds) forms the hollow portion for receiving the external candle.
  • the free flow cross-sectional area q of the outer and the inner tube is in each case that cross-sectional area (viewed perpendicular to the tube longitudinal axis), can be guided over the gas in the form of air with unburned oxygen content from outside the upper end of the float within the same to the hollow portion (outer Pipe) or air with burned oxygen content, so the exhaust air of the candle, from the hollow portion inside the float over the upper end of the same (ie above the liquid level) can be removed (inner tube).
  • the inner and outer tubes may preferably be elongated cylindrical tubes having the lengths and diameters described below.
  • a weight body is provided which can be attached as part of the float to another component or part of this float so that the center of gravity of the float in total (ie including the weight body) in the lower half of the float, preferably in the region of the lower end thereof, comes to rest.
  • the weight of the weight body can be adjusted so that the distance of the center of gravity of the float to the upper end thereof is 0.9 times the total length of the float and the distance of the center of gravity from the lower end of the float is 0.1 times the total length of the float is.)
  • the center of gravity of the float calculated on the basis of all components thereof, ie in particular as a common center of gravity of the outer tube, the inner tube and the weight body.
  • the center of gravity of the float should be so far in the lower half of the same, that even after receiving the candle weight in the interior of the float in the hollow section to its intended position, the position of the common center of gravity of the float and candle still remains in the lower half of the float to prevent tilting of the retractable candlelight, ie during operation of the candlelight to ensure a stable swimming or hovering same with candle in the predetermined liquid.
  • the weight body can be designed for the sealing closing of the lower end of the float.
  • the weight body is positively and / or non-positively at an open lower end of the float (ie on another component thereof, in particular the outer tube) is introduced into the same.
  • the introduction can be done by inserting or even, by providing a thread by screwing.
  • the weight body may also have a suitable depression, e.g. a circumferential recess, in which a still open before insertion lower end of the float (ie in particular the outer tube thereof) can be positively and / or non-positively introduced.
  • a simple frictional insertion (clamping) is just as conceivable as a screwing on the basis of a thread.
  • the float in particular: the outer tube thereof elongated, that is, its average extent in the longitudinal direction (from top to bottom in the swimming operation of the invention) is greater than its average extent or its diameter perpendicular thereto.
  • the ratio L / D of the mean longitudinal extent or length L of the floating body to the mean transverse extent or to the mean diameter D of the floating body is preferably more than 2, preferably more than 3, preferably more than 5, preferably more than 10.
  • Longitudinal extent L of the float preferably between 0.2 m and 2 m, more preferably between 0.3 m and 1.0 m.
  • the mean transverse extent or the mean diameter D of the floating body is preferably between 0.03 m and 0.3 m, particularly preferably 0.05 m and 0.15 m.
  • the float in particular its outer tube, its inner tube and / or its weight body can / at least partially be formed of a transparent material (glass or transparent plastic, in particular acrylic glass).
  • a transparent material glass or transparent plastic, in particular acrylic glass.
  • both the inner and the outer tube of the float as well as the position of the inner tube within the outer tube fixing struts are formed entirely of the transparent material.
  • the weight body can also be formed at least partially, that is also completely as a metal body, preferably as a silicone-coated metal body.
  • the silicone sheath can serve the sealing closure between the weight body on the one hand and the inner wall of the outer tube on the other hand during insertion of the weight body in this tube.
  • the weight body and its seal to the inner wall of the outer tube may consist of a metal core with a silicone sheath.
  • the silicone sheath can be adjusted so that it can be used from below, ie from the lower end of the float in the outer tube and this liquid-tight seals (secure clamping of the weight body together with seal after insertion of the same into the outer tube).
  • the metal core can be tuned so that it the respective overall structure of the candle light, so all the components of the float including the external candle, after insertion into the predetermined liquid with the top edge about 1 to 2 cm above the liquid level holds.
  • the inner tube can be firmly connected to the outer tube by means of thin connecting elements likewise made of glass, for example (transverse webs).
  • the length of the underwater light or its outer tube can be selected in a very large range. For example, the length can be 0.5 m, preferably lengths between 0.2 m and 2m are realized.
  • the assembly of the candlelight can be done as follows:
  • the external candle for example: tealight
  • the attachment of the float for example, consisting of the two tubes with cross braces
  • Substructure and attachment are firmly compressed (in particular: insertion of the weight body together with seal in the interior of the outer tube or in an alternative embodiment insertion of the outer tube in one in the upper side of the weight body, which has a larger cross-section than the outer tube formed Well) to substructure and essay, so in particular weight body and outer tube are sealed against each other, eg until the substructure is completely inserted in the outer tube and seals it.
  • the underwater light thereafter in any water vessel, or for example in a garden pond or in a lake, are used.
  • a candlestick in a manner not heretofore known (for example, there is an attractive contrast of fire apparently burning in the water).
  • the invention is made possible without additional use of electrical energy and in a simple technique.
  • FIG. 1 shows an inventive, retractable candle light 1 during operation, ie after introduction of the same, including the candle K therein in a filled with water W external vessel G in the form of a water-filled glass cylinder.
  • a centric positioning of the external candle (see below) in the outer tube 8 below the lower end of the inner tube 9 ensures that the above-described suction arises, is sucked in the air from the upper end 2o above the liquid level of the water W and the oxygen of the Air from the candle flame of the candle K is burned.
  • the exhaust air is continuously guided upwards again via the gas discharge shaft 6, which is formed centrally inside the outer peripheral gas supply shaft 5, and is discharged via the upper end 2o of the floating body 3. Continuous supply of the candle with the necessary atmospheric oxygen for a long-lasting burning is thus possible.
  • the length of the inner tube 9 is only two thirds of the length of the outer tube 8, but the two upper ends of these two tubes flush with the common upper end 2o of the float 3, ensures that within the lower third 8u of the outer tube 8 is a light volume (hollow portion 4) is formed, which is suitable both for receiving the sealing weight body 10 (third component of the floating body 3), as well as for receiving the external candle K.
  • the weight body 10 is also designed here as a cylinder, wherein the cylinder outer diameter is adapted to the inner diameter of the outer tube, that the weight body 10 along the axis of symmetry of the outer tube 8 and from the lower end 2u of the tube 8 forth in this tube 8 are frictionally inserted can.
  • the weight body 10 consists of an inner stainless steel cylinder which is completely covered by a silicone sheath.
  • the outer diameter of the silicone sheath of the weight body 10 is slightly larger than the inner diameter of the outer tube 8, so that a certain amount of force to insert the weight body 10 is necessary.
  • a light volume 4 having a free inner diameter corresponding to that of the outer tube 8 is formed over about two thirds of the length of the lower portion 8u along the axis of cylindrical symmetry.
  • This volume 4 serves to receive the external candle K placed on top of the weight body 10 and, in this state, together with the weight body 10, before sinking the candlelight into the outer vessel W filled with water W into the interior the outer tube 8 is inserted.
  • the volume (D / 2) 2 ⁇ ⁇ ⁇ L of the floating body 3 (or of the outer tube 8), in this case 6.25 ⁇ 50 ⁇ cm 3 on the one hand and the total weight of the floating body 3, that is the weight of the outer and the inner tube 8, 9 (determined by the density and volume of the glass walls used and the cross braces) and the weight body 10 and the weight of the candle K on the other hand are chosen here so that the average density ⁇ s of the floating body 3 (without the candle K) by 10% is lower than the average poet ⁇ w of displaced by the float 3 water W.
  • This deep position of the center of gravity ensures that the candle-filled candlelight 1 floats stable even after its sinking in the water tank G without additional brackets or the like, ie remains in the vertical or can not tip over. Entry of water through the upper opening 2o is thus prevented; the candlelight according to the invention floats stably in the external water vessel G until the candle K has burnt off.
  • FIG. 2 shown individual candle candles according to the invention 1 different length L are basically as in FIG. 1 candlelight 1 shown formed so that identical reference numerals describe identical components and only the differences are described below (outlined here is in particular the ratio of the two free cross-sectional areas q 8 / q 9 of the gas supply shaft 5 and 6 Gasabbowschachts).
  • a sealing closing of the outer tube 8 by means of the weight body 10 is realized here by the fact that the weight body 10 has a larger cross-sectional dimension than the outer diameter of the outer tube 8, wherein from the top of the weight body 10 ago a recess 11 in the form of a cylindrical cavity in the weight body 10 is inserted.
  • This cavity corresponds in its inner diameter approximately to the outer diameter of the outer tube 8, so that the latter can be inserted non-positively into the cavity (ie the recess 11) of the weight body 10.
  • the candle K is placed on the inner bottom of the recess 11 and lit.
