Description
TECHNICAL AREA

The present invention describes a tobacco head made of metal for a water pipe, comprising a headpiece covered on an upper side of the headpiece using a ventilation cover having a plurality of ventilation holes and on a lower side of the headpiece using a head flange having a plurality of head ventilation holes, as well as the use of a stamping process or laser cutting process to produce a ventilation cover having ventilation holes, a headpiece having ventilation openings, a head flange having head ventilation holes and edge recesses, and a stand having engagement tabs, stand tabs, and stand ventilation holes made of metal sheets to create a tobacco head.


PRIOR ART

A water pipe, also known under the names shisha, hookah, and nargile, is used to smoke standard, usually flavored water pipe tobacco. The structure of a conventional water pipe is corresponds in principle to that of a chemical washing bottle. The water pipe consists of at least four parts: a liquid container, also called a bowl, vase, or water bottle, a smoke column, a tobacco head, and a hose having a mouthpiece. What is of interest here is the tobacco head, which is produced as a multi-part heat regulation device from sheet metal and is available in various shapes. In some regions the head is also called a pot or bowl.


Tobacco heads made of metal are known, which have a headpiece having a receptacle space for receiving water pipe charcoal. These headpieces are designed to be closable using multiple lid rondels having ventilation holes, so that the coals can be supplied with oxygen and the water pipe charcoal can burn closed off in a controlled manner. The known metallic tobacco heads comprise a large number of individual parts that are not firmly connected and the tobacco head is detachably placed on the tobacco at a small distance. When in use, the glowing water pipe charcoal lies in the receptacle space of the tobacco head, wherein the tobacco head itself is only placed on the upper part of the smoke column. The known tobacco heads are detachably connected to the water pipe and can be easily removed, which can also happen unintentionally. There are no safety precautions taken to ensure a securely closed tobacco head. Glowing coals can easily escape and cause damage due to simple manipulation or if the water pipe falls over.


DESCRIPTION OF THE INVENTION

Disadvantages of tobacco heads for water pipes and water pipes equipped with them that are known from the prior art are intended to be eliminated by the present device.


The present invention has the object of providing a metal tobacco head for a water pipe, which is compact having few components and is easily producible and also provides a safeguard against the unwanted falling out of coals and prevents unwanted access to the receptacle space of the tobacco head.


Here a double bayonet closure is designed to achieve the object.


Variations of combinations of features or minor adaptations of the invention can be found in the detailed description, are shown in the figures, and are included in the dependent claims.

DESCRIPTION

Here a tobacco head 0 made of metal is presented as a multi-part device having detachable securely connected components. The goal was to manage with fewer individual components than the prior art and to ensure sufficiently safe storage of glowing coals. As can be seen in the exploded view in FIG. 1, the tobacco head 0 comprises, along a longitudinal axis L, a ventilation cover 1, a head piece 2, a head flange 3, and a stand 4. All components are made of sheet metal, preferably made of stainless steel having thicknesses greater than or equal to 1 mm. The components are optionally at least partially painted or powder-coated with paint or corrosion protection. Missing parts of a smoke column of a water pipe are arranged below the tobacco head 0, wherein a tobacco (not shown) is also placed under the tobacco head 0 as a heat source.


The ventilation cover 1 is preferably designed in a circular shape as a rondel and has a plurality of ventilation holes 10. Here three grouped collections of individual ventilation holes 10 are left out, which is only one possible design. Through the ventilation holes 10, coals stored in the receptacle space K of the headpiece 2 are better supplied with oxygen, without coals being able to escape from the headpiece 2 closed using the ventilation cover 1.


The ventilation cover 1 is detachably fastened on an upper edge of the headpiece 2. For this purpose, multiple ventilation cover tabs 11 are formed on the outer edge of the ventilation cover 1, which are angled from the cover plane D, as shown in FIG. 2. Even if the ventilation cover 1 were not designed as a rondel, but rather having a polygonal or elliptical cross section, the headpiece 2 can be closed by a suitable arrangement of the ventilation cover tabs 11.


The headpiece 2 is designed as a pipe socket having a thickness of greater than 1 mm made of a metal sheet. In the area of the upper edge, which faces toward the ventilation cover 1, multiple retaining webs 20 are attached or formed on. A particularly simple production option is the arrangement of through holes in which rods are fastened, which then form the holding webs 20. The sheet metal of the wall of the headpiece 2 can also be provided with sheet metal cams projecting away, which act as retaining webs 20. The cylindrical wall of the headpiece 2 encloses a receptacle space K for coals and multiple ventilation openings 21, preferably in the form of elongated holes, are arranged distributed in the wall. A total of three of these ventilation openings 21 are provided here.


By means of at least one weld seam 22, the headpiece 2 is firmly welded to the head flange 3, which is designed here as a rondel. In practice, it is better to use multiple weld seams 22 for safety reasons. The head flange 3 thus closes the lower opening of the cylindrical wall of the headpiece 2, the side of the receptacle space K facing away from the ventilation cover 1. Multiple head ventilation holes 30 are arranged in the head flange 3, which are distributed in the area of the edge and have such small diameters that no coals can escape through them. For the operative connection of the head flange 3 to the stand 4, edge recesses 31 are left out in the edge area of the head flange 3, offset from the head ventilation holes 30. The head flange 3 could also be designed here having a polygonal or elliptical cross section instead of a rondel. To simplify the alignment of the headpiece 2 relative to the head flange 3, a marking engraving 32 is arranged on the head flange 3, which can interact with a marking (not shown) on the headpiece 2.


The stand 4 is also produced from a metal sheet and, like the other components, is preferably produced using a punching press, a cutting tool, or by laser cutting. In the edge area of the stand 4, multiple engagement tabs 40 are cut out, which are bendable as indicated in FIG. 2a. To mount or fasten the tobacco head 0, multiple stand tabs 41 are formed protruding radially on the stand 4, which are bent over at 90° to the stand plane S parallel to the longitudinal axis L before the tobacco head 0 is put into operation. Using the stand tabs 41, the stand 4 and thus the entire tobacco head 0 can be fastened by being plugged or screwed onto the smoke column of the water pipe. Means that facilitate screwing, for example holes, can be arranged in at least one stand tab 41. Multiple stand ventilation holes 42 are also left out in the stand 4 as through holes in the stand plane S.


As shown in FIG. 2a, ventilation cover tabs 11 of the ventilation cover 1 in the assembled state of the tobacco head 0 interact with the multiple retaining webs 20 on the wall of the headpiece 2, wherein these components form a first upper bayonet closure. After the ventilation cover 1 has been produced, the ventilation cover tabs 11 first have to be bent by 90° around the cover plane D. For this purpose, corresponding cuts are provided on the ventilation cover tabs 11 on the cover side. The ventilation cover tabs 11 then extend, as indicated by dashed lines, along the outside of the headpiece 2. In addition to the bend by 90° in relation to the cover plane D, the course of the ventilation cover tabs 11 is to be adapted to the circumference of the headpiece 2, which is shown in FIG. 2b.


By rotating the headpiece 2 and ventilation cover 1 relative to one another, in the direction of the arrow shown in dashed lines on the cover plane D, the angled ventilation cover tabs 11 engage under the retaining webs 20, by which the first bayonet closure is formed. The angling of the ventilation cover tabs 11 is also used as a stop for the locking connection or closure of the first bayonet closure. FIG. 2a still shows the open state of the first bayonet closure.


Since the ventilation cover tabs 11 are angled and all components become hot in the usage state, this first bayonet closure can only be manipulated intentionally and advisably using a thermal insulating means, for example an oven mitt. In the event of unwanted contact with the tobacco head 0, the first bayonet closure cannot be opened inadvertently.


The head flange 3 is fastened on the stand 4 by means of a second lower bayonet closure, wherein the edge recesses 31 and the engagement tabs 40 interact. As can be seen in FIG. 2b, the engagement tabs 40 are guided in the fastened state through the edge recesses 31 and pushed over the edge of the head flange 3, so that a closure of the tobacco head 0 is achieved by means of this second bayonet closure. The stand ventilation holes 42 and the head ventilation holes 30 are now aligned, so that access for air and heat into the receptacle space K is achieved during operation, which is indicated by dashed arrows. For this purpose, the stand ventilation holes 42 and the head ventilation holes 30 each have to be left out accordingly in the stand 4 or head flange 3.


Optionally, the cylindrical wall of the headpiece 2 can be embodied having one or more circumferential beads to further increase stability. Optionally, company logos or advertising images can be engraved on the outer surface of the headpiece 2.


The advantage here is that all components are first stamped as flat parts or as pipe sockets, are provided with holes, holding webs 20 are fastened, the headpiece 2 is welded to the head flange 3, tabs 11, 41 are bent over and then connected by means of the first and second bayonet closure, which greatly simplifies production.


On the surface of the stand 4, pointing away from the headpiece 2, pressure points are optionally introduced, which are shown in dashed lines in FIG. 1. These pressing points allow better heat distribution to be achieved.


In an optimized version of the ventilation cover 1′ according to FIG. 3a, a ventilation cover handle 12 is provided, which is preferably welded to fastening points 120 on the ventilation cover 1′. This ventilation cover handle 12 improves the overall user-friendliness of the tobacco head 0.



FIG. 3b shows a slightly modified head flange 3′ having head ventilation holes 30, wherein these head ventilation holes 30 are designed as oblong holes. This allows ventilation to be increased without affecting stability.
