Description

The invention relates to a hookah crown in which carbons for heating tobacco or other non-tobacco blends or smoking substances are deposited.

BACKGROUND OF THE INVENTION

The hookah body is fitted with a crown into which the tobacco is inserted and which, according to older solutions, overlaps with aluminum foil, into which several holes are made. Instead of tobacco, it is also possible to use various non-tobacco mixtures or smoking substances, for example, mineral stones impregnated with molasses or vaporizing pastes. Incandescent embers are placed on the aluminum foil surface, or an aluminum foil spiral is inserted between them to prevent tobacco burning and carbon extinguishing. In simpler solutions, perforated aluminum foil can be replaced by a metal sieve. More sophisticated aluminum foil replacements, crown shafts known under the acronym HMS (Heat Management System) or Heat Management Device are also used in the state of the art.

An exemplary HMS is described in US Patent 9237770. It is a duralumin shaft of a crown into which carbons are inserted. It consists of a circular base with six elongated vents at the circumference of the circular base and provided with protrusions on the underside to keep the circular base spaced from the top surface of the crown, allowing air to flow. Carbons are placed on this circular base. By means of three cross screws, the circular base is connected to three columns of the circular enclosure, whereby also three elongated vents for lateral heat dissipation and ventilation are formed between the circular enclosure and the circular base by means of protruding portions of the columns along the circumference of the circular base. The upper part of the circular enclosure is freely laid on the convex hatch, which hatch is formed by an outer upper fixed convex circular lid with a fixed handle, below which the inner lower convex circular lid is pivotably attached, with three regularly spaced equal circumferentially spaced the irregularly shaped openings and the upper lid are formed by three fixed covers connected to the annular ring of the upper lid and connected at its center, the remaining parts of the upper lid being open. The fixed top lid covers correspond in shape to the bottom lid openings so that the openings can be covered by turning the top lid, or on the other hand by turning the two lids relative to each other, it is possible that the bottom lid openings are partially or completely passable. Stoppers protrude downward from the lower lid to prevent the lid from sliding off the circular enclosure during horizontal movement. A silicone wrapped handle is firmly attached to the ring of the top lid. The relative rotation of the two lids allows ventilation and thermal regulation by adjusting the size of the through hole in the lower lid. In the case of a hatch that is loosely laid on a circular enclosure, it is possible to rotate the two lids with a handle. This hatch can be manually gripped by the handle at any time and removed freely.

The disadvantage of the described system is its low service life due to the use of a swivel joint between the upper and lower lid, which is stressed due to exposure to smoke, flue gas, high temperature, possibly poor drying during cleaning and poor access during cleaning. both parts. The disadvantage of this HMS without an integrated circular fence holder is the difficulty of handling the HMS during operation, which is heated by the influence of carbon, which is done by means of pliers. The disadvantage of using a simple circular base is the possible burning of tobacco. In an alternative prior art solution, the second handle may be attached to a circular fence. The disadvantage of using two handles, one on the hatch and the other in the circular enclosure, is that it is difficult to operate with one-handed crown shaft.

- 1 GB 2018 - 388 A3

The prior art crown handles are difficult to handle, especially when smoking, when the carbons are hot. Although the crown shaft cover is provided with a handle, if the user wants to remove the entire crown shaft from its own crown, it needs a pair of pliers and a great deal of skill for this purpose. Inadvertent handling can cause hot embers to spill onto the floor or even burn the user. It is therefore an object of the present invention to provide a hookah crown shaft that is easy and safe to handle without the need for specialized pliers.

SUMMARY OF THE INVENTION

The aforementioned drawbacks are solved by a hookah crown shaft comprising an inner space defined by a heating mat from its peripheral portion with an upwardly extending side wall and a removable hatch, wherein the crown heating mat comprises at least one lower air inlet opening; the wall comprises at least one side air-vent opening in the lower half thereof, and a removable hatch with a protruding handle is disposed on the side wall, wherein the crown shaft further comprises at least two detachable fixing means for securing the side wall cohesion with the hatch lifted by the handle.

In a preferred embodiment, the fixing means is a latch extending from the peripheral portion of the hatch and by its positioning a corresponding gripping element in the upper half or at the upper edge of the side wall, preferably the latches are evenly spaced around the hatch circumference and preferably protruding radially therefrom.

In a preferred embodiment, the retaining element is a stop with a stop, a groove, a blind end groove or a hook.

The fixing means, such as latches and notches with stops, basically form a mechanical lock between the side wall and the crown shaft lid, which makes it easy to handle the entire crown shaft only with the handle extending from the lid. The user can then remove the entire crown shaft from the crown with one hand as needed.

In a preferred embodiment, the side wall is cylindrical and the hatch without protruding latches is circular and by its size and shape fits into the inner space of the crown shaft defined by the cylindrical side wall and overlaps the inner space of the crown shaft, but the hatch is through its protruding latches overlapping the lateral wall , mounted on the side wall. Preferably, the hatch without latches and handle is slightly smaller than the circumferential shape of the side walls.

In a preferred embodiment, the side wall comprises at least two height different sets of receiving surfaces for receiving the hatch by means of latches, between which height levels of the individual sets of receiving surfaces are provided in the side wall ventilation openings and / or into the inner space of the crown shaft. By selecting a different height level for the hatch seating, the air access can be controlled because at each of the hatching heights the resulting open air access area is given by the ventilation openings and / or the cutouts and / or cut-outs below the hatch level. Thus, the upper edge of the side wall does not have to be a plane cut, but can be differently cut to produce different heights at the upper edge.

In a preferred embodiment, the cut-out with the top stop has an inlet portion open, a bottom surface, an end position for hanging the side wall on the latch extending from the hatch and a stop against sliding the latch out of the side wall so that of the stop and after the latch is lifted to the final position in the suspension cut-out, when the hatch is raised with the handle, each latch is restrained by the respective stop

-2GB 2018 - 388 A3 to prevent it from sliding out of the slot, the bottom of the stopper is located lower than the final position in the slot for hanging.

The latches serve both for placing the hatch on the side wall, but also as a means behind which the side wall with the other parts of the shaft is suspended at the end of the hinged position on the hatch, allowing safe movement of the hatch to the crown. For sliding the hatch on the side wall of the shaft onto the crown and subsequently ensuring safe handling of the whole shaft on the crown by means of a handle, the cut-out is preferably such that, when the hatch is mounted, at least the back or forward movement is approximately U, V or similar but in particular characterized in that it is executed first downwards, then describes the lower part of the stopper and subsequently moves upwards in the started horizontal - forward or reverse direction to the final suspension position. Thus, the hatch latch is inserted downwardly into the lowest point of the slot by approximately oblique or perpendicular movement, further describing the lowest point of the stop, for example by horizontal movement, and further moving to a higher end position for hanging higher than the lowest point of the stop. After raising the hatch to the final hanging position, the shaft can be transferred to the crown, and the mechanical securing of both parts is then based on the principle of gravity where the rest of the crown shaft is suspended by its weight on the hatch with handle and secured in this position against horizontal displacement towards sliding out of the cutout and undesirable separation of the lid from the side wall.

In a preferred embodiment, for evenly distributing the latch forces around the perimeter of the hatch, each half of the hatch comprises at least one latch at any imaginary halving of the hatch. If there are two latches, they are preferably 180 ° apart. In a preferred embodiment, the number of pawls and the corresponding number of pawls are three, wherein the pawls are equally spaced over a 120 ° circumference of the circular-shaped lid. This number and deployment ensures sufficient system stability. However, four or more latches are also possible.

In a preferred embodiment, the at least one height-different set of surfaces for receiving the lid on the side wall is simultaneously defined at one height level by the located lower surfaces of three equally spaced 120 ° cut-outs with a stop; and from the peripheral portion of the hatch, there are three latches spaced 120 ° apart, the receiving surface for receiving the latch extending from the hatch, and hence for accommodating the entire hatch, being formed by the bottom surface of the slot.

In a preferred embodiment, one of the latches continuously passes into a handle, which is preferably provided with a thermally insulating material. The latch is substantially extended by at least one times its length relative to the length of the other latches, and a handle of thermo-insulating material is attached to this portion so that it can be securely gripped by hand. The latch portion adjacent the hatch perimeter is exposed to be slid into the recess like other latches without a handle, and hence the handle with the thermo insulating material grip extends up to this exposed portion at a distance from the hatch, preferably given by the length of the other latches.

The side wall extending upwardly from the peripheral portion of the heating pad ensures that the carbons do not slide away from the surface of the heating pad. Furthermore, this side wall together with the hatch encloses a space in which the combustion rate, as described above, can be controlled by adjusting the size of the ventilation openings and the sidecut at the top of the side wall. The side wall is provided with at least one side opening in the lower half to provide air flow from the surroundings into the interior of the crown shaft where the air is heated and further flowing through the bottom opening or openings in the heating pad to the tobacco or other blend or smoking substance in the crown . The side openings in the lower half of the side wall are preferably arranged at the lower edge of the side wall near the heating pad. The location and overall surface area of these openings have an effect on the combustion process, therefore, they are preferably located in close proximity to the heating pad to improve the intake air flow around the vertical walls inside the positioned carbons, thereby avoiding extinction of the carbons being heated more uniformly from all sides. . In a preferred embodiment, three elongated side openings are provided at the lower edge of the side wall.

-3 EN 2018 - 388 A3

The shape of the heating pad corresponds to the shape of the crown neck so that the heating pad rests on the crown neck and covers the entire crown. The hot air and smoke formed by the hot carbons in the crown shaft pass through the lower opening in the heating pad to the tobacco or other blend or smoking substance in the crown. In a preferred embodiment, the lower openings in the heating mat are more, for example, six elongated lower openings, which are spaced regularly in a circle at the outer edge of the heating mat as elongated vents.

The cover can advantageously be provided with at least one upper opening for the passage of air and faster glowing of the carbons. Due to the top opening located in the center of the hatch, air is also flowing through the top wall inside the embedded carbons, ensuring a better oxygen supply.

A removable circular hatch 6, see Fig. 4, is disposed on this side wall 4, with three latches 9 radially extending from its peripheral portion at 120 °, where one of the latches 9 continues to flow smoothly into a handle 8 embedded in a wooden handle 10 with thermally insulating properties. . The hatch 6 defines the inner space of the shaft 1 for the crown from above. The annular portion of the lid 6 is of such a diameter that it fits tightly into the cylindrical shape of the side wall 4, the latches 9 extending from the lid 6 then exceed the inner diameter of the cylindrical shape of the side wall 4 as shown in FIG.

In another exemplary embodiment, the handle 8 may be designed, for example, as an ear on the lid near the center of the lid or the like.

The fixing means for securing the consistency of the side wall 4 with the cover 6 when it is lifted by the handle 8 are, on the one hand, latches 9 and as their counterparts - retaining elements in the side wall 4 are cut-outs 11 with a stop.

In another exemplary embodiment, a hook is used as the retaining element, which is inverted so that it can hang on the latch 9 or latches 9 in another exemplary embodiment into a groove provided in the side wall 4. These grooves can be guided along a helical path or horizontal and only short, for example blind at one end.

At the upper edge of the side wall 4, against these latches 9, one set of three notches 11 with a stopper having lower faces 19 at one lower height level and a second set of three notches 11 with a stopper having lower surfaces 19 at one higher height level is provided, see Figs. 1, 2, 3, 8 and 9. These lower surfaces 19 are then the bearing surfaces for receiving the cover 6 by means of the latches 9. As can be seen from Fig. 10, these cut-outs have an inlet part 20 open from above, the end position 21 for hanging and are supplemented by a stop 12 against sliding of the latch 9 from the side wall 4. The lower part of the stop 12 is positioned lower than the end position 21 for hanging. Upon insertion of the latch 9 into the inlet portion of the slot 11, the latch 9 is guided and slid about the lower portion of the stop 12 and is further lifted to the final suspension position 21. After lifting the hatch 6 by means of the handle 8, each latch 9 is engaged by a corresponding stop 12, see FIG. 1, 9 and 10.

In an alternative exemplary embodiment, each of the three sets of slots 11 comprises two slots 11 regularly spaced around the periphery of the circular hatch 6 and correspondingly disposed by two latches 9 therein, three sets of slits 11 at three height levels being formed at the upper edge of the side wall 4. In another exemplary embodiment, a set of equally spaced four hooks and a corresponding set of four latches 9 on the circular hatch 6 are provided at the upper edge of the side wall 4.

The notch 11 with the stop has the shape of a bath, see. 1, in which the latch 9 is inserted downwardly, then guided approximately straight around the stop 12 and is subsequently lifted by moving in the started horizontal direction by raising the hatch 6 to the end position 21 for hanging.

In an alternative embodiment, the cut-out 11 is V-shaped or in another exemplary embodiment the cut-out end of the cut-out is stair-shaped in particular of the bottom surface 19 allowing multiple height positions in a single cut-out 11. The cut-out 11 may also describe an incomplete square, letter U and the like.

One latch 9 in this exemplary embodiment is substantially extended by at least about ten times its length relative to the length of the other latches 9, since this extension results in a handle 8 on which the thermo-insulating material - wooden shaft 10 is attached so that the handle 8 can be gripped by hand; made safe transfer of the shaft 1. to the crown. The portion representing the latch 9 adjacent to the hatch perimeter and adjacent to the handle 8 is exposed so that the latch 9 can be inserted into the slot 11 just like the other short latches 9 and hence the handle 8 with the wooden shaft 10 adjoins the exposed portions at a distance from the hatch. 6, given by the length of the other latches 9, see FIGS. 4 and 8.

-5 EN 2018 - 388 A3

The wooden shaft 10, see Fig. 1, was manufactured separately and a recess was inserted into which a handle 8 having a tree-like expanding shape was inserted by pressure, see Fig. 4. A hard heavy exotic wood type was used for the wooden shaft 10 Wenge. In an alternative less preferred embodiment, a sufficiently long grip has been used for gripping not wrapped with a layer of thermo-insulating material that is manipulable by hand or hand protected by thermo-insulating material, such as thermo-insulating rubber fingers, glove and the like.

In this exemplary embodiment, the side wall 4 is cylindrical and the lid 6 without protruding latches 9 has a circular shape and by its size and shape fits into the cylindrical side wall 4 and overlaps the inner space of the shaft 1 on the crown. which extend beyond the side wall 4, are mounted on the side wall 4. The lid 6 without the latches 9 and the handle 8 is slightly smaller than the circumferential shape of the side walls 4 so as to fit into them.

At the upper edge of the side wall 4, ventilation openings 13 are provided between the upper and lower hatch support height and below the hatch support height, and the specific sidecut and shaping of the upper side wall 4 to form slots / openings between the hatch and the side wall 1 and 8, which allow air to enter the interior of the crown shaft.

The area of the available ventilation openings 13 in the upper half of the side wall and the slots / openings formed between the cutouts / cuts / shaping of the upper edge of the side wall 4 and the stowage cover 6 is adjustable by the height-adjustable cover 6. see Fig. 8, wherein the lower surfaces 19 of the slots 11 serve as bearing surfaces for the hatch 6. However, the height positions of the bearing surfaces may, in other exemplary embodiments, be more or only one, and these bearing surfaces need not be provided at .

In this exemplary embodiment, six ribs 14 are equally spaced and protruding from a ring of 2 mm thin aluminum material on the top surface of the heating pad 2, and the annular ring is attached to the heating pad 2. The zebra 14 provides carbon storage at a distance from the heating pad 2 and the better air supply to the carbons. The ring is designed not to overlap the bottom openings 3 in the heating mat 2, in this embodiment, for example, that the ring mounted on the heating mat 2 comprises six equally spaced but slightly enlarged lower openings 3 and all lower openings 3 of the warm mat 2 are fully through . Zebra 14 are preferred, but need not be present at all, or their number and shape may be altered, replaced by a grid and other similar means.

The shape of the heating pad 2 corresponds to the shape for mounting on the circumferential shape of the neck of the crown 17 and at the periphery of the heating pad 2, six elongate lower openings 3 for air passage are regularly spaced. The heating pad 2 is supported by three legs 15 which ensure that the crown shaft 1 does not slide off the crown, see Fig. 2. These legs 15 are part of the side wall 4 and threaded through the specially formed holes in the heating pad 2 and the holes in the ring 2, 3 and 6. The heating mat 2 is preferably made of 2 mm thin aluminum sheet.

The circumferential shape of the lid 6 corresponds to the cylindrical shape of the side walls 4 and the circular shape of the heating pad 2 so that the lid 6, with its edge, abuts the side walls 4 of the shaft 1 and covers the inner space thereof. The cover 6 is provided with one upper opening 7 for air passage and faster glowing of the carbons 18, see Fig. 1. The material of the cover 6 is 1 mm thin stainless steel. However, there may be a plurality of openings, for example, they may also be perforated in a hatch, etc.

The side wall 4 is made of 1.5 mm thin stainless steel, made of a tube of 70 mm diameter.

In one exemplary embodiment, it protrudes perpendicularly from the heating mat 2, but in alternative

A3 of the exemplary embodiments may also be a widening or tapering shape or a curved shape. Advantageously, from the lower edge of the side wall 4, regularly spaced 3 [deg.] 3 legs 15 extend through specially formed holes in the heating pad 2 and in the ring with ribs 14. These legs 15 after tilting through said holes fold into the center of shaft 1 ° from the original direction. Further, from the lower edge of the side wall 4, folds 16 are passed through special holes in the heating mat 2 and in the rib ring 14 which hold the heating mat 2 and the rib ring 14 together, see Figs. 2, 3 and 7. Number of legs 15, folds 16 and corresponding apertures formed therefor may vary.
