Description

The invention relates to a chimney attachment for a shisha, which is placed on a head of the shisha when in use.

A shisha, for example, is also called a water pipe or hookah. A chimney attachment is also called a heat management utensil, heat management device or smokebox.

From the DE 20 2013 012 125 U1 discloses a heat management utensil for hookahs with a bowl designed to hold glowing charcoal and conduct heat into tobacco. The hookah heat management tool rests on the bowl of the hookah with the plate in direct contact with the bowl of the hookah. The plate conducts heat from the charcoal or other heat source directly into the tobacco or other combustible material contained in the bowl, providing an optimal temperature to create smoke, which then flows into the inner tubes of the hookah through the water in the base and finally into the hose and finally to the user.

The problem is that such a chimney attachment only rests loosely on the head and can fall off it, e.g. if a user hits the water pipe. For example, glowing charcoal in the chimney attachment poses a danger to persons and property.

The object of the invention is to propose improvements in relation to a shisha.

The object of the invention is achieved by a chimney attachment according to claim 1. Preferred or advantageous embodiments of the invention and other categories of the invention result from the further claims, the following description and the attached figures.

The chimney attachment is one for a hookah head. The head is one for or for receiving incense to be smoked, in particular tobacco or the like, here referred to as “tobacco” for the sake of simplicity. The head is an "intended" head for the chimney attachment insofar as its dimensions to be expected, in particular a diameter range of possible heads of shishas, are known. The invention therefore assumes that such heads are known for which the chimney attachment is intended. The chimney attachment is therefore designed in particular to be placed on corresponding heads with such characteristics of hookahs. Viewed the other way around, it is assumed that, in addition to the chimney attachment according to the invention, a wide variety of other commercially available chimney attachments can also be placed on corresponding hookah heads. In this respect, the chimney attachment is similar to commercially available chimney attachments in that it can be used with corresponding shishas or heads, i.e. it can be placed on them and fulfills a corresponding functionality for operating the shisha (heating the smoke mechanism).

The chimney attachment includes a body. The base body is set up to accommodate fuel for heating the tobacco, in particular it contains a combustion chamber for this purpose. This applies to the operation of the shisha, i.e. when the chimney with hot fuel is placed on the head of the shisha. In particular, the base body contains a corresponding receptacle for the fuel, for example a floor, in particular in the form of a grid, a storage area, etc.

The base body can be placed on the head in a position of use or actually placed on during operation/use, for example a bottom of the chimney attachment is then placed on the head. In particular, the base body itself is placed or placed loosely on the head, i.e. the base body considered in isolation is not held on the head, except that it is supported by it. The usage position is also an intended usage position, e.g. this means that the base body is placed on the head in a specific orientation, e.g. with its bottom. The intended use position, properties, orientations such as "up, down" ... of the described components etc. always refer to the regular operation of the chimney attachment or the shisha, in particular an upright position of the shisha, if e.g. a main body of the shisha (water vessel etc.) is positioned in a correspondingly intended, e.g. upright position, for example standing on a floor or a table. As a result, their head is "up" and the chimney attachment is in turn placed "up" on their head.

The main body has a head direction. The head direction is a direction-oriented axis that runs in particular centrally through the base body. In the position of use of the chimney attachment on the head, the head direction is directed towards the head or towards a receiving area for the head, ie points from the base body to where the head is or should be located. In the following, for the sake of simplicity, the "head" is sometimes also spoken of when, strictly speaking (in the absence of the head), its up scope is meant. In particular, the direction of the head then runs vertically and through the head or its chimney and coincides with a central longitudinal axis of the head. The head direction is fixed to the base body and is therefore an orientation or directional property of it.

The mantel includes at least two arms. These extend away from the base body in the direction of the head. "In the direction of the head" means that these are parallel or oblique to the direction of the head; at least one larger, in particular the only directional component of the direction of extension of the arms points in the direction of the head, a smaller component or none runs transversely to the direction of the head. The arms can also extend in other ways, so the above statement then only applies to part of the arms.

The arms are arranged concentrically to the direction of the head (in the sense that the direction of the head is an axis), i.e. around it, in particular they are arranged regularly around the direction of the head and/or in particular designed symmetrically to the direction of the head.

The arms are in a resting position. The resting position is when there is no other force (apart from gravity) exerted on the arms, e.g. they are freely extended in the air. The rest position is therefore that state of the chimney attachment in which it is not moved out of its rest position against the spring force.

The arms therefore enclose or delimit the head or—if this is not present—the recording area in which the head is to be placed as intended or in the position of use comes to rest. This applies both to the rest position and to the use position, when the head actually rests between the arms and therefore the head rests in the receiving area.

In at least one, in particular several, in particular all of the arms, at least a respective movement section of the arm can be moved out of the rest position, the direction of movement here being radially outward from the head direction (axis), i.e. away from it. The movement section can also take up the entire arm. The arm / chimney top reacts with a spring force that wants to return it to the rest position, i.e. radially inwards towards the head direction (axis). The spring force is thus directed towards the head direction (axis). The spring force thus brings about a return to the rest position when no external force acts on the arm or movement section. The statements made apply to the section of the arm that extends away from the base body in the direction of the head; other parts of the arm can perform other movements. This therefore applies to that area of the room with regard to the chimney attachment in which the head of the shisha is in a state of use/operation of the chimney attachment. As a result, the arms can therefore also be referred to as spring arms.

According to the invention, there is a chimney top with (spring) arms that enclose a head when placed on it. When placing the chimney top on the head, the arms or the movement sections are expanded radially outwards against the spring force, for example by hand. After releasing the arms, they spring radially inwards towards the head direction and thus back towards the head and are thus in contact with the head with a corresponding spring force. This results in at least one frictional connection between the arms and the head, so that the chimney attachment is held on the head by friction thanks to the arms. This at least makes it more difficult or even prevents the chimney attachment from falling off the head or the shisha. In particular, this increases the operational safety of the chimney attachment and the entire shisha in relation to hot fuel, e.g. glowing coal, which is in the chimney attachment.

The invention is based in particular on the intended use of the chimney attachment or operation of the shisha with the chimney attachment. In this operation, the shisha stands upright in particular, so that the head forms the top end of the shisha. The chimney attachment rests on top of the head and supplies it or the incense burner in the head with heat from above. The arms reach down from the chimney top, past the head, and clamp the head between them due to the essentially horizontal, radially inward-acting spring force.

In particular, all arms are made the same. In particular, the chimney cap contains exactly three arms. In particular, the chimney cap contains exactly two arms. The arms are arranged concentrically around the head direction (axis) in particular in a uniformly distributed manner in the circumferential direction.

In a preferred embodiment, the chimney attachment is dimensioned such that a smallest inscribed circle in a plane transverse to the direction of the head between the arms—when they are in the rest position—has a predeterminable or predetermined maximum diameter. Again, that area of the arms is addressed that extends away from the base body in the direction of the head, ie where a head of a shisha comes to rest during operation. The inscribed circle or inscribed circle is one in a plane transverse to the direction of the head (axis) running circle, which touches all arms from the inside. To find the smallest inscribed circle, the axial position on the head direction with the smallest inscribed circle diameter is searched.

The maximum diameter is in particular 3 cm or 3.5 cm or 4 cm or 4.5 cm or 5 cm or 5.5 cm or 6 cm. The invention is based on the assumption that the chimney attachment is only used for heads or shishas with those that have a diameter greater than the maximum diameter. This means that the arms always have to be deflected radially outwards from the rest position when they are placed on any of the heads in question, and it is thus always ensured that the arms actually press against the head due to the spring force in the attached state.

In a preferred embodiment, at least one, in particular at least exactly two, in particular several, in particular all, of the arms lying opposite one another with respect to the direction of the head has a fixing section. At least in the resting position of the arms--viewed in a plane transverse to the head direction (axis)--the fixing section partially surrounds the head direction. The fixing section therefore follows in particular the shape of a circular arc or a comparable shape, such as part of an ellipse, a polygon, etc. In particular, the fixing section extends over a circumferential area around the head direction (axis) of at least 10 or 20 or 30 or 45 or 60 or 90 or 120 degrees. This results in the particular advantage that even with a chimney top with exactly two arms, the arms and thus the chimney top are held securely on the head, since the arms then at least partially encompass the head with their fixing sections.

In a preferred embodiment, at least one, in particular several, in particular all, of the arms has at least one elastic section. The elastic section can also take up the entire arm. The movement section of the arm can be moved in that the elastic section can be elastically deformed against at least part of the spring force from a basic shape corresponding to the rest position. This means that the elastic section assumes or returns to its basic shape in the rest position (no external forces, see above). The "part of the spring force" is to be understood as follows: if several and thus other resilient elements are provided in the chimney attachment, which possibly cause a spring force, further parts of the spring force can also be generated by one or more of these other elements. If the elastic section is the only spring element in each case, the spring force is generated as a whole by the elastic section. The same also applies to the other embodiments explained below for generating a spring force. The elastic deformability therefore means that the elastic section reacts in a resilient manner when it is elastically deformed from its basic shape. Corresponding elastic sections lead to mechanically particularly uncomplicated arms or chimney tops.

In a preferred embodiment, at least one, in particular several, in particular all, of the arms has at least one rigid section which is non-deformable in the technical sense/in normal operation, ie rigid. Corresponding to the above, the entire arm can also be designed as a rigid section. The movement section of the arm can then be moved in that the rigid section is movably or movably mounted on the base body against at least part of the spring force (see above) out of the rest position (see above). In contrast to the above (elastic section), the rigid section is not deformed to generate the spring force, but rather moved as a rigid form relative to the base body.

In particular, the rigid section, in particular the entire arm, is mounted on the base body so that it can pivot about a pivot axis. In particular, the pivot axis runs transversely to the direction of the head and/or tangentially to a circle around the pivot axis, which runs transversely to the pivot axis. In particular, the chimney attachment contains at least one spring element that acts between the arm, in particular the rigid section, and the base body and generates at least part of the spring force. The spring element is in particular a helical spring, leaf spring, in particular a torsion spring or torsion spring or torsion spring.

In particular, at least one, in particular several, in particular all of the arms is resiliently mounted on the base body, in particular pivotably.

The embodiments with a rigid section lead to particularly durable chimney attachments that are particularly simple in terms of material.

In a preferred embodiment, at least one, in particular several, in particular all of the arms contains an active compound. The effective mass is in particular a concentrated element that is smaller (in particular at least a factor of 5, 10, 20 or 30) than the entire arm. In particular, it is an additional element attached to or molded onto the rest of the arm. The chimney attachment is set up so that, in the position of use, at least part of the spring force (see above) is absorbed by the force of gravity acting on the active mass is generated. The active mass is therefore in particular a mass part introduced in or on the arm specifically for this purpose, which in particular has more mass (in particular at least a factor of 2, 3, 4, 5 or 10) than the entire rest of the arm. The chimney attachment is set up in such a way that, in the position of use, the gravitational force acting on the active mass generates at least part of the spring force (see above), which in turn leads to a clamping force of the arm on the head. Thus, the chimney top is held at least partially on the head by gravity. In other words, a kind of deflection/gear is created in order to deflect a vertically acting gravitational attack on the active mass into a particularly horizontally acting spring force/clamping force of the arms on the head.

In a preferred embodiment, at least one, in particular several, in particular all, of the arms is arranged radially on the outside of the base body in relation to the head direction (axis). As a result, given the dimensions/diameter of the base body, the arms are attached to the base body in the area or on or outside of this diameter and can thus also encompass the largest possible hookah heads. Viewed another way, given the arrangement of the arms (span, capacity for heads), the base body can be kept as small as possible. In addition, this opens up the following possibility in particular:

In a preferred embodiment, at least one, in particular several, in particular all, of the arms extend at least partially past the base body in the opposite direction to the head. The arms can also extend right next to the base body or past it or even protrude beyond it in the opposite direction to the head direction. This can also lead to optically particularly attractive arms in the form of “pinnacles”, “wings” or “thorns” projecting upwards in the position of use. In particular in combination with an articulated mounting of a rigid arm on the base body, this can lead to a lever character of the arm: In other words, by radially inward movement of an "upper" (opposite to the head direction beyond an articulated mounting) arm section / end of the arm in the direction of the head from Main body away projecting portion of the arm are moved radially outwards. This makes it particularly easy to overcome the spring force, e.g. by hand, in order to place the chimney attachment on a head with "open" arms. It is also particularly easy to remove the chimney top from the head, for example.

In a preferred embodiment, at least one, in particular several, in particular all, of the arms has an inner line pointing radially inward with respect to the direction of the head in all intended positions of use. "All intended positions of use" are in particular all possible pivot positions of pivotable arms or all positions of use of elastic arms that do not exceed the elastic limits (within which a complete return takes place). For heads of all sizes, which can thus be encompassed by the arms, there is always an inner line that runs radially inward with increasing distance from the base body (direction of the head).

This inner line offers—obviously depending on the head actually gripped—at least the possible possibility of gripping behind a possible radially inward recess of a head in the direction of the head in a form-fitting manner. The inner line has in particular at least one form-fitting section or contains it. The form-fitting section is in particular shaped concavely towards the head direction.

In other words, this results in a hook-like configuration of the arm, a projection on the arm, a curvature on the arm, etc. All of this can form a form fit with corresponding heads, which extend, for example, along their direction of extension (i.e. downwards in the operating position) from the Taper the head end away (i.e. in the position of use in the direction of the head away from the base body). The corresponding embodiment has the effect that, at least when using the chimney attachment with certain heads, there is an improved holding effect of the chimney attachment on the head, since in addition to the friction fit described above, there is also a form fit when the arms rest against the head when in use. The shape of the arms can, for example, be selected empirically in such a way that the most effective possible form fit results with a large number of common, customary, widespread heads and this effect can at least probably be achieved during operation. The form-fitting effect here is purely due to shaping in a radial plane with respect to the direction of the head. It is therefore merely an addition to a radially acting frictional connection. What is not meant by the "form fit" here is in any case a form-fit engagement of an arm in a counter-element on the head that is specially provided for this purpose / that is tailored to the arm.

In a preferred embodiment, at least one of the arms is designed in the form of a flat component, which extends flatly in a radial plane with respect to the direction of the head. This leads to radially particularly stiff and stable arms. Also, this can be too visually special attractive embodiments of arms in the form of "wings", "merlons" or "thorns".

The object of the invention is also achieved by a chimney set according to patent claim 11. This contains the chimney attachment according to the invention and a manipulator for handling the chimney attachment in all the intended operating states. "Intended operating states" are in particular a cold state (storage, preparation for operation) and a hot state. The latter describes the situation when hot fuel, for example glowing coal, is placed in the chimney attachment and this has reached its operating temperature of several 100 °C in particular. Since the chimney attachment can no longer be touched with bare hands, especially when it is hot, without burning oneself, the manipulator allows the chimney attachment to be handled at any time.

In a preferred embodiment, the manipulator and/or the chimney top each contain at least one magnetic element. The chimney set is set up so that for handling, i.e. in particular when the magnetic element / manipulator / chimney attachment is placed on the corresponding counterpart (manipulator or chimney attachment), a holding force between the chimney attachment and the manipulator is caused by the magnetic element. Particularly simple and visually appealing solutions of manipulator and/or chimney attachment can be realized with a corresponding magnetic element. A corresponding magnetic element or a corresponding chimney set is also particularly wear-free. If only one magnetic element is present, the respective counterpart (manipulator or chimney attachment) is then made of a corresponding material at least at one attack/acting position/area of the magnet, on which a magnetic force can be generated by the magnetic element.

In a preferred embodiment, the manipulator and/or the chimney attachment contains a release device that interacts with the magnetic element. Actuation of these causes an increase in the distance between the magnetic element on the one hand and the chimney attachment and/or manipulator on the other hand. This creates a greater distance between the magnetic elements or between the magnetic element and the counterpart, the magnetic force decreases, the elements can be detached from one another, in particular they then detach themselves due to gravity when the elements are oriented appropriately to one another. This means that the manipulator and chimney attachment do not have to be pulled apart by hand to release the holding force caused by the magnetic element, but the corresponding release can be accomplished by actuating the release device. This also protects in particular from the need to touch the hot chimney attachment with your hand.

In a preferred embodiment, the manipulator and the chimney top each contain at least one form-fitting element that is coordinated with one another. A releasable form-fitting connection between the manipulator and the chimney attachment can be effected or effected in the coupled state by the form-fitting elements. In other words, the manipulator can positively attack the chimney top to enable handling. After handling, the form fit can be released so that the manipulator can be removed from the chimney attachment again. In this way, particularly simple chimney sets can be implemented.

The object of the invention is also achieved by a head assembly according to patent claim 15. This contains a chimney attachment according to the invention or a chimney set according to the invention. In any case, the header group also contains the header mentioned. The head is thus part of the head group, so that the chimney attachment can be specially tailored to this head, so that it can be held particularly well here, for example. Nevertheless, the chimney attachment can also be used on other heads.

The object of the invention is also achieved by a hookah according to patent claim 16. This contains a chimney attachment according to the invention or a chimney set according to the invention or the head group according to the invention.

The shisha and at least some of its possible embodiments and the respective advantages have already been explained in connection with the chimney attachment according to the invention.

As an alternative to the chimney attachment explained above, the object of the invention can also be solved by a cuff arrangement with a cuff for the base body and the at least two arms, the arms then being provided on the cuff. The cuff is in turn designed to be fastened to a base body by being guided around it all the way around. The base body is in particular a commercially available or customary chimney attachment, which, however, does not have the arms according to the invention. The subject matter of the invention is therefore also a collar for a base body of a chimney attachment without the base body itself. Otherwise, the above statements relating to the chimney attachment according to the invention also apply to the collar. In particular, all the above-described embodiments of the Chimney attachment also embodiments of the cuff assembly.

In particular, the cuff is set up for attachment to the base body in that it is designed to be elastic in order to enclose a base body after expansion and to press around it in a resilient manner. The cuff is made in particular from an expandable, heat-resistant material, in particular a silicone material.

In a preferred embodiment, the cuff is designed as an expandable, band-shaped ring, which is placed around a base body in the expanded state, so that it contracts after it is released and, due to its elasticity, is held tightly on the base body, stretching radially inward. For example, the sleeve is dimensioned in such a way that its dimensions, material properties, etc. are tailored to a selection of base bodies in the form of common, commercially available chimney attachments. For example, a diameter of an unstretched elastic cuff smaller than the smallest expected diameter of an intended selection of base bodies is selected and the extensibility is sufficient to be able to encompass base bodies with the largest expected diameters while always offering a secure hold.

1 shows a section of a shisha 2, of which, however, only the upper end, namely the head 4 is shown. "Up" refers here to the illustrated regular or intended operating position of the shisha 2 when it is perpendicular to a direction of gravity 6, ie upright, for example on a floor or a table. “Up” is then oriented counter to the direction of gravity 6 . The shisha 2 or the head 4 is built in the usual way. The head 4 therefore contains an internal chimney 8, which here runs perpendicularly in the direction of gravity 6, through which smoke (not shown) can be drawn. To generate the smoke 4 tobacco 12 is inserted in a cup 10 of the head. In order to smoke the tobacco 12, a chimney attachment 14 is placed on top of the head 4 or the hookah 2. The chimney attachment 14 contains a base body 16 with a combustion chamber 18, not explained in detail here, for receiving fuel 22, which is delimited by a floor 20 lying below. The bottom 20 forms a recording or recording device for fuel 22, here glowing charcoal. The heat of the fuel 22 radiated through the base 20 smokes the tobacco 12 during operation. The entire chimney attachment 14 and thus also the base body 16 is in a position of use GL by being placed on the head 4 of the hookah 2, which is vertical in the operating position, at the top or is attached.

The base body 16 has a head direction 24 which is fixed relative to the base body 16 and penetrates the base 20 centrally and perpendicularly. The head direction 24 describes or represents, on the one hand, an axis which, on the other hand, also has an orientation of the axis, namely away from the base body 16 or its bottom 20, in this case downwards. The head direction 14 thus points from the floor 20 away from the chimney attachment 14. Due to the position of use GL of the base body 16 on the head 4, the head direction 24 is aligned parallel to the direction of gravity 6. In the position of use GL shown, the head direction 24 penetrates the head 4 or its central chimney 8 vertically and centrally.

2 shows the arrangement 1 from "below", ie looking in the opposite direction to the direction of gravity 6. All four arms 26 are shown here.

The chimney attachment 14 contains a total of four arms 26, of which 1 only two are shown or visible. The arms 26 are fastened to the base body and extend away from the base body 16, here its bottom 20, in the direction of the head 24 (its orientation is important here). Regarding “in the direction of the head 24” the following can be said: Although the direction of extension of the respective arms 26 also runs at an angle to the direction of the head 24, the directional component of the direction of extension in the direction of the head 24 is decisive, because this is greater than the directional component of the extension of the arms transversely to the direction of the head 24 The arms 26 are (see 2 ) arranged concentrically around the head direction 24, ie they have the same radial distance to the head direction 24 and are each offset by 90° in the circumferential direction. The arms 26 have a respective rest position RL, which is shown in FIGS 1 and 2 is shown in dashed lines. The rest position RL is given when no external forces are acting on the arms 26 (gravity should not be considered here). The arms 26 would therefore assume the rest position RL in the present case if the chimney attachment 14 were not in contact with a head 4, but the arms 26 would extend without force and freely in the air.

The arms 26 delimit (particularly in the rest position RL, when no head 4 is present) a receiving area 27 for the head 4. As soon as the head 4 is actually present, it lies in the receiving area 27 as intended.

The arms 26 each have a movement section 28 which in this case corresponds to the entire arm 26 in each case. By the action of an external force, in this case manual bending of the arms 26 radially outwards (relative to the head direction 24), for example by a user when placing them on the head 4, the respective movement section 28 can be moved from the rest position RL against a spring force FK with respect to the head direction 24 are moved radially outwards. After removal of the external force, in this case releasing the arms 26, the arms 26 rest against the head 4 and reach the position of use GL shown here. The spring force FK now acts on or in the arms 26 and presses them radially inwards against the head 4. This creates a frictional connection between the arms 26 and the head 4, so that the entire chimney attachment 14 is securely on the head 4 thanks to the spring force FK held and thus protected against falling.

The chimney top 14 is dimensioned as follows: First, a smallest inscribed circle 30 in a transverse plane (here perpendicular to the plane of the paper) to the head direction 14 is determined, which can be inscribed between the arms 26 when they are in the rest position RL. This may have at most a predeterminable maximum diameter HD, here 3 cm, which is exactly the case here. Since the heads 4 of commercially available hookahs 2, for which the chimney attachment 14 is intended, each have an outer diameter of more than the maximum diameter, i.e. greater than 3 cm, it is ensured that with any of the intended heads 4 on which the chimney attachment 14 is placed , In the position of use GL, the arms 26 are moved radially outwards from their rest position RL and the spring force FK is thus present in order to generate the above-mentioned frictional connection.

In the present case, the spring force FK is generated as follows: The arms 26 have respective elastic sections 32 (marked hatched), which only take up part of the arm 26 here. The movement section 28 can be moved in that the elastic section 32 can be elastically deformed against the spring force FK from a basic shape GF (directed obliquely inwards here, corresponding to the rest position RL). This elastic deformation is necessary when placing the chimney top 14 on the head 4 in order to bend the arms 26 radially outwards. Due to the elastic properties of the elastic section 32, the spring force FK results as an elastic restoring force of the elastic section 32.

3 shows in a view according to 2 an alternative chimney cap 14 placed on the head 4. This know an identical base body 16, but only two arms 26 on. These are basically the same as those from the 1 and 2 executed, ie also have elastic sections 32 on. In a modification to the above, however, the arms 26 here have a respective fixing section 34 (marked hatched in the figure) which, in the rest position RL (shown in broken lines) in a transverse plane (here the plane of the paper) to the head direction 14, partially encompasses the head direction 14. The fixing section 34 is also elastic here, which is why it rests or nestles against the outside of the head 4 in the position of use GL and thus ensures that the chimney attachment 14 is held securely on the head 4 even with only two arms 26 .

4 shows in a representation according to 1 an alternative head 4 and chimney top 14. The chimney top 14 has here again four (only three shown) arms 26, which correspond to the 1 , 2 evenly distributed concentrically around the head direction 24 are arranged around. The arms 26 do not have elastic sections 32 here, but rather rigid sections 36 which occupy the entire arm 26 here. The movement section 28 (shown hatched) is formed here by an end of the arm 26 pointing in the direction of the head 24 . The movement section 28 can be moved and brought radially outwards from the rest position RL (indicated by dashed lines) in that the rigid section 36 is movably mounted on the base body 16 . This takes place as a result of pivot mounting about a pivot axis 38. Here, too, the movement from the rest position RL shown in dashed lines requires work against a spring force FK. This is brought about here by a spring element 40, which is only indicated symbolically, here a torsion leg spring in the area of the pivot axis 38. This causes a torque DM of the arms 26 or the rigid sections 36 in relation to the base body 16. The torque DM causes the radially inward (regarding Head direction 24) acting spring force FK.

In the present case, each arm 26 also contains an active mass 42 , here an additional weight that is massive compared to the rest of the arm 26 . In the usage position GL, part of the spring force FK is generated by the gravitational force SK acting on the active mass 42 . This is because the force of gravity SK also generates part of the torque MD about the pivot axis 38, which amplifies the spring force FK generated by the spring element 40.

In this exemplary embodiment, all of the arms 26 are also arranged radially on the outside of the base body 16 in relation to the head direction 24 . They also not only extend away from the base body 16 in the direction of the head 24 but also past the base body 16 in the opposite direction to the direction of the head 24 , so that they protrude beyond the latter in the opposite direction to the direction of the head 24 .

The arms 26 also have an inner line 44 pointing radially inwards in every position of use GL (defined here by the mechanically possible pivot angle of the arms about the pivot axis 38). This engages behind an existing head 4 in the head direction 24 radially inward recess 45 of the head 4. In addition to the above-described frictional connection, this also creates a form fit between the arms 26 and the head 4, which allows the chimney attachment 14 to be lifted off the head 4 against the head direction 24 and tilting at the head 4 is further aggravated.

The arms 26 are also designed here as flat components, which extend flatly in respective radial planes away from the head direction 24 . In 4 the radial planes 46 run both perpendicularly to the plane of the page and in the plane of the page.

5 shows an alternative chimney top 14 in top view, which is from 4 corresponds, but is equipped here with three instead of four arms 26.

Can be seen in the 4 and 5 also permanently open ventilation openings 48 in the base body 16, which are designed here in the form of a crown for design reasons, as well as adjustable draw openings 50. The draw openings 50 can be closed by rotating a cover 52 of the base body 16 about the head direction 24 in relation to its lower part 54, in that no further details are given in FIG explained way the draft openings 50 in the lower part 54 by screens 51 (see 10 ) are not, partially or completely closed.

6 shows one of the arms 26 in the form of the wing-like flat components from FIGS 4 and 5 in detail, in particular its mount for the pivot axis 38 and the course of the inner line 44.

The 7 until 10 show cover 52 and base 54 in detail 5 , which are decorated in terms of design by a crown symbol in the form of the ventilation openings 48 and by a crown-shaped design of projections or elevations, which are not explained in detail, on the top and bottom of the base 20 of the chimney attachment 14 and lower part 54 . The draft openings 50 are formed here in that a wall surrounding the combustion chamber 18 is formed in the manner of a battlement by means of rectangular incisions (in relation to the position of use GL “from above”). The incisions between the battlements (wall sections) form the draft openings 50.

7 shows an alternative embodiment of the lower part 54 for a hatched portion 55a of the figure. Here the base 20 is designed without a circumferential depression. The floor 20 is therefore smooth or even up to the edge of the lower part. Alternatively or additionally, a projection on the bottom 20 (see also 9 ) are omitted. The only elements protruding downward from the base 20 in the position of use GL are then the crown-shaped extensions, which protrude from the base 20 to the receiving space (cup 10) for the tobacco 12.

8th shows a further alternative embodiment of the lower part 54 for a hatched portion 55b of the figure. A in the main part of 8th the "ash edge" shown is then omitted. Here, too, only the elevations, which are crown-shaped here, protrude upwards into the combustion chamber 18 .

In a further alternative embodiment, not shown, could in the 7 until 9 the draft openings 50 can also be formed in the form of openings in an annular wall surrounding the combustion chamber 18, which is flat at its upper edge (use position GL).

The same applies alternatively or additionally to the panels 51 in 10 . These could also be designed as fixed parts of a perforated ring wall, which protrudes downwards from the cover 51 (position of use GL). This annular wall could then also run flat at its lower edge.

By rotating the cover 52 and lower part 54, the openings in the annular walls can then be brought into alignment (open draft to the combustion chamber 18) or completely or partially (no or less draft)) closed by the respective wall sections of the other annular wall. This variant is in the 9 and 10 dashed only symbolically indicated.

11 shows a fireplace set 56, which according to the chimney attachment 14 1 (Shown symbolically) and a manipulator 58 contains. This allows manipulation or handling of the chimney attachment 14 in its operating conditions, especially when it is hot. The manipulator 58 is a handle that is not explained in detail and contains a magnetic element 60 on an inner pin 66. For the purpose of handling, the magnetic element 60 generates a force between the chimney attachment 14 and the manipulator 58, here by magnetic attraction of the chimney attachment 14 when it rests on it. The chimney attachment is then attached or held to the manipulator 58 in a magnetically detachable manner.

The manipulator 58 also contains a release device 62. In the present case, this is formed in that the magnetic element 60 is attached to the inner pin 66, which is surrounded by an outer sleeve 64. Both elements are axially displaceable relative to one another in the direction in which the inner pin 66 and outer sleeve 64 extend. To release the manipulator 58 from the chimney attachment 14, the outer sleeve 64 is advanced over a front end of the inner pin 60 on which the magnetic element 66 is located. As a result, the magnetic element 60 is lifted off the chimney top 14, the magnetic force decreases, and the chimney top 14 is detached from the manipulator 58, as in FIG 12 shown. The release is dashed and indicated by an arrow.

13 shows functionally symbolically (the number, position and orientation of form-fitting elements 68b on the manipulator 58 would have to be adjusted) an alternative manipulator 58 for the embodiments of the chimney attachment according to FIG 4 until 10 or with arms 26 according to 6 . Here the manipulator 58 and the chimney attachment 14 have positive-locking elements 68a, b that are coordinated with one another. The form-fitting element 68a is here a thickening at the (upper) end of the arms 26, the form-fitting element 68b is a T-shaped tapering slot in a manipulator body 70. By hooking / inserting the form-fitting elements 68a of the arms 26 into the form-fitting elements 68b or their tapered section creates a form fit and the chimney attachment 14 can be raised. The chimney attachment 14 is released from the manipulator 58 by releasing the form-fitting elements 68a from the form-fitting elements 68b in a correspondingly reverse manner.

In the figures, the head 4 and the chimney cap 14 each form a head assembly 72. The head assembly 72 may also include the head 4 and the chimney set 56.

Both the chimney attachment 14 and the entire chimney set 56 and the head group 72 can also be part of the shisha 2 .
