Definitions
- the present invention describes a tobacco head made of metal for a water pipe, comprising a headrest, which is covered on an upper side of the headrest with a ventilation cover with a plurality of ventilation holes and on an underside of the headrest with a head flange with a plurality of head ventilation holes, and the use a stamping process or laser cutting process for producing a ventilation cover with ventilation holes, a head piece with ventilation openings, a head flange with head ventilation holes and edge recesses and a stand with engaging tabs, stand tabs and stand ventilation holes from sheet metal to create a tobacco bowl.
- a water pipe also known by the names shisha, hookah and nargile, is used to smoke commercially available, mostly flavored water pipe tobacco.
- the structure of a conventional water pipe corresponds in principle to that of a chemical washing bottle.
- the water pipe consists of at least four parts: a liquid container, also known as a bowl, vase or water bottle, a smoke column, a tobacco bowl and a hose with a mouthpiece.
- a liquid container also known as a bowl, vase or water bottle
- a smoke column a tobacco bowl and a hose with a mouthpiece.
- the tobacco head which is made of sheet metal as a multi-part heat control device and is available in various forms. In some regions, the head is also referred to as a pot or head.
- Tobacco bowls made of metal which have a headrest with a receiving space for receiving water pipe coal. These headrests come with several round covers Ventilation holes can be closed so that the embers can be supplied with oxygen and the charcoal can burn in a controlled manner.
- the known metallic tobacco bowls comprise a large number of individual, non-fixed individual parts and the tobacco bowls are detachably placed on the tobacco at a small distance.
- the glowing charcoal for the hookah lies in the receiving space of the tobacco head, with the tobacco head itself only being attached to the upper part of the smoke column.
- the well-known tobacco bowls are detachably connected to the hookah and can be easily removed, which can also happen undesirably. There are no safety precautions that ensure a securely closed tobacco head. Glowing charcoal can easily spill out and cause damage with simple manipulation or if the hookah falls over.
- the present invention has set itself the task of creating a metal tobacco head for a water pipe which is compact with few components and easy to produce and also prevents coal from falling out unintentionally and prevents unwanted access to the receiving space of the tobacco head.
- a double bayonet lock is designed here to solve the problem.
- FIG. 1 shows an exploded view of a tobacco bowl made of sheet metal, directly after manufacture, prior to secure assembly.
- FIG. 2a shows a perspective view of the tobacco head from above, with the components so far only being laid on and not yet connected in a secured manner by means of a first upper and second lower bayonet lock, while
- FIG. 2b shows a perspective view of the section from FIG. 2a from below, with a ventilation cover being releasably fixed to a headrest by means of a first bayonet lock and a head flange being releasably secured to a stand by means of a second lower bayonet lock.
- Figure 3a shows a perspective exploded view of a modified ventilation cover
- Figure 3b shows a perspective view of another head flange. Description
- a tobacco head 0 made of metal is presented here as a multi-part device with components connected in a detachably secured manner. The aim was to get by with fewer individual components than the state of the art and to ensure sufficiently safe storage of glowing coal.
- the tobacco head 0 comprises a ventilation cover 1, a headrest 2, a head flange 3 and a stand 4 along a longitudinal axis L. All components are made of sheet metal, preferably made of stainless steel with thicknesses greater than or equal to 1 mm . Optionally, the components are at least partially painted or powder-coated with paint or anti-corrosion protection. Missing parts of a smoke column of a water pipe are arranged below the tobacco head 0, with a tobacco, not shown, also being placed under the tobacco head 0 as a heat source.
- the ventilation cover 1 is preferably circular in shape as a rondelle and has a plurality of ventilation holes 10 . Here three grouped accumulations of individual ventilation holes 10 are cut out, which is only one possible design. Charcoal stored in the receiving space K of the headrest 2 is better supplied with oxygen through the ventilation holes 10 without charcoal being able to escape from the headrest 2 closed with the ventilation cover 1 .
- the ventilation cover 1 is detachably attached to an upper edge of the headrest 2 .
- several ventilation cover tabs 11 are formed on the outer edge of the ventilation cover 1, which are angled away from the cover plane D, which is shown in FIG.
- the head support 2 can be closed by a suitable arrangement of the ventilation cover tabs 11 .
- the head restraint 2 is designed as a pipe socket with a thickness of greater than or equal to 1 mm made of sheet metal. In the area of the upper edge, which faces the ventilation cover 1, several holding webs 20 are fastened or formed.
- a particularly simple manufacturing 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 head support 2 can also be provided with sheet metal cams which protrude and which act as holding webs 20 .
- the cylindrical wall of the head connector 2 encloses a receiving space K for coal, and a plurality of ventilation openings 21, preferably in the form of oblong holes, are distributed in the wall. A total of three of these ventilation openings 21 are provided here.
- the headrest 2 is firmly welded to the head flange 3, which is designed here as a rondelle.
- the head flange 3 thus closes the lower opening of the cylindrical wall of the head socket 2, the side of the receiving space K facing away from the ventilation cover 1.
- Several 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 coal can escape as a result.
- edge recesses 31 are cut out in the edge area of the head flange 3 , offset from the head ventilation holes 30 .
- the head flange 3 could be configured with a polygonal or elliptical cross-section instead of a roundel.
- an engraved marking 32 is arranged on the head flange 3, which can interact with a marking on the headrest 2, which is not shown.
- the stand 4 is also made of sheet metal and, like the other components, is preferably made with a stamping press, a cutting tool or by laser cutting. Several engagement tabs 40 are cut out in the edge area of the stand 4, which are bendable as indicated in FIG. 2a.
- a plurality of standing tabs 41 are formed on the stand 4, projecting radially away, which are bent over by 90° to stand plane S parallel to the longitudinal axis L before the tobacco head 0 is put into operation.
- the stand tabs 41 With the stand tabs 41, the stand 4 and thus the entire tobacco head 0 can be attached or screwed to the smoke column of the water pipe.
- Means that facilitate screwing, for example bores, can be arranged in at least one standing bracket 41 .
- Several stator ventilation holes 42 are cut out as through-holes in the stator plane S in the stator 4 as well.
- ventilation cover tabs 11 of the ventilation cover 1 interact with the several holding webs 20 on the wall of the head connector 2, these components forming a first upper bayonet lock.
- the ventilation cover tabs 11 must first be bent by 90° around the cover plane D. Corresponding incisions are provided on the ventilation cover flaps 11 on the cover side for this purpose.
- the ventilation cover tabs 11 then run, as indicated by dashed lines, on the outside along the headrest 2. In addition to bending by 90° to the cover plane D, the ventilation cover tabs 11 should be adapted in their course to the circumference of the headrest 2, which is shown in Figure 2b.
- FIG. 2a still shows the open state of the first bayonet lock.
- this first bayonet lock can only be manipulated intentionally and advisablely using a heat insulating means, for example an oven mitt. In the event of unintentional contact with the tobacco head 0, the first bayonet lock cannot be opened unintentionally.
- the head flange 3 is fastened to the stand 4 by means of a second lower bayonet lock, the edge recesses 31 and the engagement tabs 40 interacting.
- the engagement tabs 40 are guided through the edge recesses 31 in the fastened state and pushed over the edge of the head flange 3, so that the tobacco head 0 is closed by means of this second bayonet lock.
- the stand ventilation holes 42 and the head ventilation holes 30 are now aligned, so that air and heat can access the receiving space K during operation, which is indicated by dashed arrows.
- the stand ventilation holes 42 and the head ventilation holes 30 must be recessed in the stand 4 or head flange 3, respectively.
- the cylindrical wall of the head socket 2 can be designed with one or more circumferential beads in order to further increase stability.
- company logos or advertising images can be engraved on the outer surface of the headrest 2. The advantage here is that all components are first punched as flat parts or as pipe sockets, are provided with holes, retaining bars 20 are attached, the headrest 2 is welded to the head flange 3, tabs 11, 41 are bent and then using the first and second bayonet lock are connected, which greatly simplifies production.
- a ventilation cover handle 12 is provided, which is preferably welded to the ventilation cover 1' at attachment points 120. This ventilation cap handle 12 improves the overall user-friendliness of the tobacco head 0.
- FIG. 3b shows a slightly modified head flange 3' with head ventilation holes 30, these head ventilation holes 30 being in the form of oblong holes.
- the ventilation can be increased without affecting the stability.
