The invention relates to a floating lantern, containing a cap for placing at least one light source or lighting means and connected to the base of the canopy covering the light source, the screen having a hole for connection with the base of the lantern, and the rest closed, in particular, generally spherical surface, and the area of contact between the light screen and the base of the lamp is provided by sealing or sealing element and a sealed area of contact between the base of the lantern and light screen in the working position is below the surface of the surrounding floating lantern fluid, and the floating lantern is connected, at least one passing below the liquid surface and are connected by an anchor or angerami there fixing element.

From US-A-5176552 already known floating lantern described above genus, containing the principal light source base and connected to it, covering the light source is a light box that has a hole for connection with the base of the lantern, and at the base of the lamp affects the fastening element, which Sankaran under the surface of the fluid surrounding the floating lantern. Because the area of contact between the base of the lantern and light screen in the working position, at least temporarily, may be neapolitanische water, in the area of contact between the base of the lantern and light screen provided by a gasket or sealing element.

In the working position on the floating water light and, in particular, spherical light screen are large lifting force, while in contrast, the base of the lamp, connected by an anchor through at least one fastening element may not emerge. These forces acting on the base of the lantern, on the one hand, and light screen, on the other hand, constantly load thus provided in the zone of contact between these parts of the lantern gasket that this can be eventually leaking.

Comparable floating lantern known from EP 0907865 B1, in particular from figure 3. Also with the help of such floating flashlight can illuminate bodies of water, and floating lantern can be provided anywhere in the pond, swimming in it.

The base of the lantern contains in this case the electric cable and configured to anchor.

Already made attempts anchoring pedestal lantern with restraint.

In these cases, however, it turned out that the wind or the waves, or other loads between the base of the lantern and light screen may force acting in the direction of separation of these two parts. Anchoring attempts at erati base, while lifting force or the force of the wind load light screen against this ankerwyke efforts. Because of this, there is a danger that over time in a sealed area of contact will occur leaks and the fluid or water will penetrate into the floating lantern. This can happen primarily when the seal is used as a gasket or sealing element and is constantly under pressure, gradually tired and its material will lose its elasticity or even rejected, or will spread under the action of compression.

Therefore, faced with the task of creating a floating lantern above-described kind, which, despite anchoring to the area of contact between the base of the lantern and light screen, not the effort or, at least, applied only a little effort.

To solve this task it is provided that the light screen effect, at least one connected with a floating lantern fastening element.

Since the fastening element from floating lantern, according to the invention, the effect on the luminous screen and not on the base of the lantern, holding effort to light the screen, and not to the base of the lantern, so provided on the luminous screen efforts can at least largely be perceived fastening element, i.e., not the place with the organisations between the light screen and the base of the lamp and thereby sealed area of contact. Thanks to this solution is therefore even possible to slightly pull the floating lantern under the water against its lifting force and therefore firmly of sankarit it, because then acting on the luminous screen of the lifting power of the load is not the connection with the base of the lantern, and directly fastening element or fastening elements. However, with a weakened first fastening element, which gives a floating lantern certain freedom of movement, effort, caused for example by wind or waves, perceived that the fastening element.

Light screen can have at least one docking location for fixing one or more acting as a pull element fastening elements, and the submerged end of the pull element or elements may be located anchor, cargo hook, loop, etc. Thus, the fastening element or fastening elements in the working position are not visible because they are in the most largely or even are almost completely under water.

Particularly favorable, if the circumference length of the screen there are several, for example three or four, fixing fixing or pulling elements, in particular at the same height, and/or evenly distributed around the circumference and when in the working position, at least, is one of these places fastening and/or at several places pinning effect the fastening element. Thus, the user has different possibilities of positioning and fixing the floating lantern on the water surface, such as a pond, etc. and it can also provide a certain freedom of movement.

It is possible that there is acting under the water on the fastening element or fastening elements load, the force of which, in particular, more lifting capacity floating lantern in the surrounding liquid. Thus, the floating lantern with the help of such goods is fixed by means of the fastening element or fastening elements, however, can change its position by changing the location of the cargo. Place (s) of restraint fixing (holding) light screen fasteners (fasteners) may be placed (located) on a plot of approximately spherical light screen, which in the working position is lower than the maximum horizontal diameter and, in particular, under water. The place or places of fastening are then plot the spherical light screen, which is compared with the maximum horizontal length is decreasing in size, so made, usually in the form of pickup elements, the fastening elements can be directly from a place of attaching stretched to the place Askerov is or shifted to it without having a location on the side surface of the light screen. When placed in operating position under water area almost not visible then not only these fasteners, but also places the dock.

The place or places of attachment to the surface of the light screen can be separated from the internal space of the light screen recess, groove, lugs, lug or hook. Thus, in this area, primarily in the manufacture for one, cannot access water from entering the light screen, so that the area of its fastening requires no special sealing means.

The place or places of fastening may be located on a surface of the light screen in deepening this surface and completely drowned in this pit. Due to this, at the same time the fastening of the fastening element in this dock is well protected and is almost not visible even in the relatively clear liquid.

Spherical surface light screen below the zone of maximum horizontal diameter can move in a narrowing down in the working position of the surface in the form of a truncated cone, the lower edge of which is located an inlet for pressurized cap of the flashlight. Thus, in working position mostly under water zone floating lantern occurs conical or tapered shape, which mailspoolsent stability of a floating lantern in its floating position.

Place fixing for anchoring floating lantern can be located on a plot of luminous screen having a surface in the shape of a truncated cone. Place of fastening may be, therefore, are relatively close to the place of contact between the base of the lantern and light screen, so that when tensile efforts to consolidate these can occur minimally small or short arms of the lever.

Part of the base of the lantern, acting against the opening in the light screen outside, and in the working position down, may have a surface in the shape of a truncated cone or spherical, and it can generally continue with the shape of a truncated cone section of the light screen or Supplement in an elongated truncated cone or a cone. Thus, the lowest usually place the floating lantern occurs relatively evenly pointed or conically tapering shape, which accordingly provides a stable floating position, since the cap with a light source or lighting means relatively low shifts the center of gravity of the entire device and spontaneously takes care that the base of the lantern had more vertically below the midpoint of the length of the screen.

Made in the form of the pull element, the fastening element can represent what Eriko, cord, cable or chain, if necessary, the rod or rod.

First of all, when the combination of individual or several of the above signs and measures arises floating lantern, which can be Sankaran under water without the provision of this anchoring unwanted efforts on the area of the seal between the base of the lantern and light screen. Thus, it is possible to use arbitrary anerousis efforts depending on whether the floating lantern as stiff as possible to stay at his place or desirable whether a certain freedom of movement, in which the floating lantern can move on the surface in a limited area. This prevents that the retaining force exerted by the fastening element or elements on a floating lantern, will exert a force separation of the encapsulated area of contact between the base of the lantern and light screen.

Below is an example of carrying out the invention are described in more detail using the drawings. They partly schematically depict:

- figure 1 is a floating lantern in the working position, are connected by an anchor using connected by an anchor below the water surface of the fastener and the anchor on the bottom of the reservoir, on which it floats;

- 2 - the corresponding figure 1, where instead of an anchor of the anchoring element under water provided the station is located on the bottom of the reservoir load;

- 3 - the corresponding figures 1 and 2, where the retaining floating lantern fastening element below the surface of the water with his converts from a floating lamp end hanging from the noose;

- figure 4 is a vertical section consisting of a base and length of the screen, floating lantern, and the light source, for clarity, are not shown;

- 5 - the corresponding figure 4 cut length screen without pedestal lantern;

- 6 - the lower side of the light screen with views of the place of attaching one or more fasteners for anchoring the light of a lantern in the pond.

Indicated, in General, POS. 1 floating lantern contains a light source or lighting means, which for clarity is not shown. This source of light or is it the lighting means is arranged to accommodate the base 2 of the lamp as shown and described in EP 0907865 B1.

The base 2 of the lantern is made with the possibility of connection with covering the light source or illuminating means light screen 3, which is depicted in figure 1-4 and also approximately corresponds to the design in EP 0907865 B1.

Light screen 3 has a hole 4 with internal thread 4A (figure 5) for connection with a suitable to her male thread socket 2 of the lamp, as seen primarily in joint consideration figure 4 and 5. In the rest of the light screen 3 is accommodated and has a generally spherical surface. In zone 6, the contact between the light screen 3 and the base 2 of the lamp provided by the sealing by the sealing ring 5, which is made in the form of a ring of circular cross section, but may be performed as described in EP 0907865 B1. In any case, due to the threaded connection between the cap 2 and a lantern light screen 3 sealing element or o-ring 5 is pressed against the respective sealing surfaces, so that a sealed area 6 of contact between the cap 2 and a lantern light screen 3 in the working position can be located below the surface 7 surrounding the floating lantern 1 liquid and use, therefore, is practically not visible.

Figure 1-3 shows that in the light screen 3 in the working position is at least one running surface 7 of the liquid and connected by an anchor or ankaray there the fastening element 8. Exerted on the floating lantern 1 retention efforts of this fastening element 8 is transmitted, therefore, the light screen 3, and not on the base 2 of the lantern, so that even with increased effort sealed a place cannot be loaded in the sense of weakening the seal, and as the load increases, the pressure on the sealing ring or sealing element 5 may even be increased in the sense of improving the upl is titeling actions if, for example, a floating lantern 1 with increased force to pull a little deeper into the liquid, so that a particularly reliable and to position it in a certain place.

Light screen 3 has figure 1-5, at least one seat 9 pin and 6 - even three places 9 fixing one or more fastening elements 8 made in this example in the form of a drawing element. At this location 9 fixing distributed around the circumference at the same height and evenly. Thus, at each location 9 pin or figure 1-3 at the selected location 9 consolidation can affect one fastening element 8, in particular, in the form of a drawing element.

On under water, drawn from the floating lantern 1 the end of the fastening element or elements or pulling elements 8 in figure 1 can be located anchor 10, figure 2 - cargo 11, and figure 3 is situated on the limit loop 12 than fixing or pulling element 8 may be fixed under water. While it can be relatively strongly stretched or suspended in a weakened form, in order to give a floating lantern 1 if necessary, on the surface 7 of the water a certain freedom of movement, so that it can change its position by wind or currents in a predetermined limited range.

Acting on the fastening element or elements 8 the waters of the th load 11 is thus suitable for the mass or of a magnitude, which exceeds the lifting force of the floating lantern 1 in the liquid. Thus, it is possible, however, to change the position of the load 11, and thereby the floating lantern 1, however, the floating lantern with its lifting force cannot carry the load and within the reservoir to be displaced in an undesirable manner under the influence of wind. The consumer has, however, compared to anchored in figure 3, however, the possibility of installing a floating lantern largely arbitrary location within the reservoir.

There is a possibility of pre-selecting and/or adjusting the length of the fastener, so as to make adjustment to the ponds of different depths and/or to give a floating lantern 1 more or less freedom to drift on the surface 7 of the water.

Place 9 of the fastening holding the light screen 3, and thereby the floating lantern 1 of the fastening element 8 is located on a plot of approximately spherical light screen 3, which in the working position figure 1-3 is lower than the maximum horizontal diameter and, in particular, under water. Practically designated 9 fixing are located directly next to the zone 6 contact with the base 2 of the lantern.

Figs.4-6 places 9 anchoring on the surface of the light screen 3 is made in the form separated from the internal space of the light screen 3 wall 3A of the recess or groove 1 with the property, there is a lug 14 on the ledge 15. Place 9 of the fastening is made, therefore, in one piece with the light screen 3. In this case, the docking location, namely, in the exemplary embodiment, the eyelet 14 is located on a surface of the light screen 3 in the recess 13 of this surface and is fully recessed in the recess or notch 13. Thus, by placing the fastening element 8 in the light screen 3 on its surface there is almost no ledge, though, in particular, below the surface 7 of the water would be possible also acting place 9 fastening.

Figure 4 and 5 shows that the spherical surface of the light screen 3 below the site of his greatest horizontal diameter enters tapering down in the working position of the surface in the form of a truncated cone, the lower end of which has an inlet opening 4 for sealed cap 2 of the lamp, i.e. the zone 6 of contact. Place 9 fixing for anchoring floating lantern 1 are located on this land the light of the lamp 3 having a surface in the shape of a truncated cone. This improves the transmission input effort and gives a floating lantern 1 in the process of swimming is also a better stability of its position in the liquid, even if the fastening element 8 is weakened and floating lantern can float relatively freely.

Part of the cap 2 of the lantern, acting against the opening 4 in vetovo screen 3 out, and in the working position down is in the sample surface in the shape of a truncated cone or a spherical surface, which basically continues the plot of the light of a lantern in the shape of a truncated cone, i.e. complements the luminous screen on its bottom side in an elongated truncated cone or a cone. Thus, the floating lantern 1 has a lower, conically tapering section, which stabilizes its basically a vertical floating position, which also contributes to the weight of the cap 2 of the lantern with the light source or illumination means.

Made in the form of the pull element, the fastening element 8 may be a rope, cord, cable or chain, if necessary, the rod or rod. An additional 1-3 still visible electrical cable 16, which provides lighting tool shock itself does not serve for anchoring. Due to the mounting element 8 can, on the contrary, to avoid this electrical cable 16 due to any movements or loads on floating lantern 1 was in turn exposed to tensile force.

Floating lamp 1 socket 2 for placement of the light source or lighting means and connected to the base 2 of the canopy covering the light source light screen 3 having an inlet 4 for connection with the base 2 of the lantern, and the rest closed, cha is in the surrounding area, mainly a spherical surface, contains in zone 6, the contact between the light screen 3 and the base 2 of the lamp seal, in particular a sealing element or o-ring 5, so that a sealed area 6, the contact may be in the operating position below the surface 7 of the liquid, which should float floating lantern 1. In order to fix the floating lantern 1 in such a fluid is stationary or only with a slight freedom of movement, in the light screen 3 in the working position is at least one passing below the surface 7 of the liquid and ankaray or connected by an anchor there the fastening element, so that when operating in this fastening element 8 the efforts of area 6, the contact is not loaded as it would be when mounted on the base 2 of the lantern.
