Description

The starting point of the invention is a grill with a height-adjustable ember tray. The invention further relates to a grill that can be assembled and stowed away in a space-saving manner after disassembly in a packaging state, as well as an ember pan for a charcoal grill.

Various grills are known from the prior art, which provide for height adjustment of a grill base, in particular a glow tray.

That's what the document says DE 93 08 061 U1 a grill with a height-adjustable grill floor (ember pan). The height is adjusted using eccentrics located under the grill base. The eccentrics are connected to a torsion bar that can be rotated using a lever. Other adjustable grills in which the height of the grill floor (ember pan) is adjustable are described in the documents DE 32 20 527 A1 , DE 298 00 683 U1 and DE 298 00 685 U1 described.

Furthermore, additional references are made to the publications DE 93 03 912 U1 , US 2019/0053661 A1 , US 10,219,653 B1 and DE 20 2013 004 305 U1 referred.

The publication DE 93 03 912 U1 discloses a grill with a heating unit held in a frame or frame and a food support supported at a vertical distance from the heating unit, the distance between the heating unit and the food support being adjustable in different ways, the height of the food support and/or the heating unit being at least one parallel guide gear having a handle is adjustable.

The invention is based on the object of providing a grill with an improved adjusting device for adjusting the height of a grill base, in particular an ember pan. The adjusting device should be designed to be smooth, reliable and lockable in an almost infinitely variable manner. In addition, the adjusting device should have a small space and material requirement.

Furthermore, the grill should be easy to assemble (assemble) and disassemble without tools, as well as being able to be stowed away to save space. In addition, the grill should provide a grill floor in the manner of an ember pan for a charcoal grill, which prevents the ember pan from warping due to the effects of heat.

The invention relates to a grill with a height-adjustable ember tray. The term ember pan refers to a pan for an electric gas grill equipped with a heating element or an ember pan for a charcoal grill. When we talk about the ember pan below, it can also be a grill base of an electric gas grill, so that the grill base and ember pan can be used synonymously.

In addition to the ember tray, the grill includes a frame, preferably consisting of four frame legs and four side parts, as well as a grate and an adjusting device for adjusting the height of the ember tray. The grate and the adjusting device for adjusting the height of the ember pan are arranged on or between the side parts.

In other words, the height of the ember pan can be adjusted using the adjusting device.

It is provided that on two opposite first sides of the grill, each within the grill formed by the first and second side parts, torsion bars are arranged horizontally mounted in the second side parts, which are connected to at least one ember pan pivot lever arranged below the ember pan, the torsion bars also are each connected to a torsion bar lever leading out of the first side parts of the grill, so that when at least one of the torsion bar levers pivots from a starting position of the torsion bar lever, a rotational movement of the respective torsion bar is caused about an axis of rotation. This simultaneously causes a pivoting movement of the ember pan pivoting lever carrying the ember pan, which raises or lowers the ember pan on the side of the actuated torsion bar lever.

According to the invention it is provided that each of the torsion bar levers is coupled outside of the grills formed by the first and second side parts with an adjusting lever arranged on the side of the first side parts and pivotable about a pivot axis, the adjusting levers being connected to one another via an adjusting rod which is located laterally on one of the second Side parts are arranged.

An actuation of the adjustment rod is transmitted from the starting position via the adjusting levers to the torsion bars, which raise and lower the ember pan pivot levers on both sides of the grill independently of one another, with the ember pan resting on the two ember pan pivot levers, and the ember pan is raised overall with the movement of the adjusting levers or is lowered, with the ember pan when the adjustment rod is in an inclined position in one direction or the other compared to an imaginary horizontal is arranged, is raised or lowered on one side.

According to the invention, an adjustment kinematics is thus formed, which are arranged inside and outside the side parts of the grill in the assembly of the grill, and which interact in such a way that easy and comfortable operation of the grill is possible, as explained in the description.

It is preferably provided that the respective torsion bar lever and the respective adjusting lever are connected to one another by means of a push-through connection, which transmits the pivoting movement of the respective adjusting lever to the respective torsion bar lever.

It is preferred that the adjusting levers are mounted on one end so that they can pivot about the pivot axis by means of an adjusting lever bearing in the first side parts of the grill.

Furthermore, it is preferably provided that the adjusting levers can be locked independently of one another at a predeterminable height in recesses which are arranged in first side parts of the frame by means of a locking pin arranged on the adjusting lever.

The adjusting levers are preferably adjustable independently of each other in a limiting slot by means of a limiting pin arranged on the adjusting lever, the limiting slots being arranged in the first side parts and having a certain slot length, so that the respective adjustment height is limited, since the limiting slots for the limiting pins engaging in the limiting slot each form an end stop.

Finally, it is preferably provided that two ember pan pivot levers are arranged on the respective torsion bar, which carry the ember pan, the ember pan pivot levers being connected to one another parallel to the torsion bar by means of a cross bar, whereby a U-shaped bracket is formed, each of which is arranged on one side below the ember pan and the ember tray is height-adjustable on one or both sides.

The side parts arranged opposite each other are of the same length and therefore belong together in pairs.

The adjusting device for adjusting the height of the ember pan therefore consists (essentially internal kinematics) of at least torsion bars, ember pan pivot levers and torsion bar levers.

According to the invention it is provided that the torsion bar arranged on two opposite sides of the grill is mounted horizontally in the first side parts.

The torsion bar is preferably mounted in the angled sections of the first, in particular short, side part.

Furthermore, it is provided that the respective torsion bar is connected to the at least one, preferably two, ember pan pivot levers which are arranged below the ember pan and can be pivoted upwards and downwards from the horizontal position, as well as to each torsion bar lever which leads out of the side of the grill.

Through the direct or indirect movement of the torsion bar lever leading out of the grill, the ember pan pivot levers, which can be pivoted up and down, can be moved.

When the torsion bar levers are pushed down, the ember pan pivot levers are raised and when the torsion bar levers are pushed up, the ember pan pivot levers are lowered.

This means that the ember pan resting on the end of the at least one ember pan pivot lever can be raised or lowered and the grill temperature on the grill grate can thus be varied in an advantageous manner.

Due to the torsion bars arranged on both sides with the at least one or the ember pan pivot levers arranged thereon, the height of the ember pan can advantageously be adjusted differently on both sides.

The adjusting device is advantageously of simple construction and requires little space, since the torsion bar is preferably arranged within the grill. Furthermore, the adjusting device is advantageously easy to operate and, in principle, infinitely variable. Different locking options can be provided.

In a preferred embodiment of the invention, it is provided that the torsion bar levers arranged on the torsion bar each extend counter to the direction of the ember pan pivot lever and are each movably connected to an adjusting lever mounted in the frame from the side parts by means of the push-through connection, as is explained in detail in the description.

The adjusting levers are preferably each mounted in a side part by means of an adjusting lever bearing, so that they are parallel to the first side part (in the assembled state) can be pivoted in a vertical direction.

Due to the pluggable connection of the torsion bar levers, which are led out laterally from the preferably shorter first side parts of the grill, with the adjusting levers stored there and arranged to the side of them, the torsion bar levers can each be moved with the adjusting levers (external kinematics). When the adjusting levers pivot, a pivoting movement of the respective torsion bar lever is caused, ultimately causing the ember pan to move up and down. Screws whose head is designed as a ball are preferably used as torsion bar levers.

To make it easier to operate the adjusting levers, they are preferably guided to the grill operator on the side parts. This advantageously simplifies the operation of the adjusting device and reduces the risk of burns.

In a further preferred embodiment of the invention it is provided that the adjusting levers arranged on both sides can be locked in recesses arranged in the side parts of the frame by means of a locking pin arranged thereon. This provides an advantageous, easy-to-use locking device for the adjusting device. Ultimately, the ember pan can advantageously be easily locked at the height that can be predetermined by operating the adjusting device.

Furthermore, it is provided that the adjusting levers (external kinematics) are connected to one another by an adjusting rod (external kinematics).

The connection of the adjusting levers via an adjustment rod of the external kinematics enables simple and convenient handling. This also ensures that the grill operator is at an operating distance from the grill.

The external kinematics therefore include the adjusting levers and the adjusting rod, which connects the adjusting levers.

In a further preferred embodiment of the invention it is provided that the ember pan pivot levers of a torsion bar are advantageously connected to one another to form a U-shaped bracket, whereby the support of the ember pan for height adjustment of the ember pan is improved.

The invention further relates to a grill that is easy to assemble, disassemble and assemble.

The grill includes a frame, preferably consisting of four short frame legs for a table grill and four long frame legs for a stand grill, four side parts as well as a grate and an ember tray. The side parts arranged opposite each other are of the same length and therefore belong together in pairs. The design of the table grill and the stand grill or the completion of the table grill into a stand grill is explained in detail in the associated description.

According to the invention it is provided that the second side parts of the frame can each be suspended in corresponding receptacles of the first side parts of the frame. The first side parts of a rectangular grill are preferably the shorter side parts.

The longer side parts are hung, for example, with hooks, connecting pins or other connecting elements in the corresponding receptacles of the first side parts.

The legs of the frame can be inserted into the leg receptacles, which are each arranged on the underside of the first side parts, and locked there.

Furthermore, it is provided that the grate is placed on support sections arranged on the side parts, while the ember pan rests on the adjustable ember pan pivot levers.

The assembly of the main components of the grill can therefore be carried out easily and advantageously without tools.

According to a further preferred embodiment of the invention, a floor pan/ash pan arranged below the ember pan can be fastened to the side parts, in particular by means of snap fasteners.

Slot or elongated hole-like openings are advantageously provided in the side parts, which protrude into the snap fasteners provided for fastening the floor pan. The base pan is preferably attached to the longer side parts with the snap fasteners, which also serve as closure elements for storing the grill in the disassembled packaging state. The floor pan can therefore be attached in a simple manner.

Furthermore, it is provided that shielding plates can be hooked into the side parts on the inside of the side parts. The shielding plates advantageously reduce the heat radiation to the side parts and thus reduce heat losses and in particular the risk of burns.

According to a further preferred embodiment of the invention, it is provided that the legs of the frame and the leg receptacles are designed as an angle profile and/or carrying handles and/or frame connectors are arranged on or between the frame legs.

Frame legs designed as angle profiles are stable and inexpensive. Together with the corresponding leg holders, easy and quick assembly is advantageously possible. The frame connectors arranged between the frame legs can increase the stability of the grill. At the same time, shelves can be arranged on it, for example to keep grilled food warm. The carrying handles can be used advantageously for moving the grill and for hanging tools such as grill tongs.

In a further preferred embodiment of the invention, it is provided that the connections of the carrying handles and frame connectors to the frame legs are carried out by connecting pins each formed with an annular groove and locking plates that can be inserted into the annular grooves, the locking plates each being provided with recesses that are compatible with the annular groove. In this way, simple, quick and tool-free assembly and disassembly of the carrying handles and frame connectors is advantageously possible.

According to a further preferred embodiment of the invention, it is provided that the frame legs are connected to the leg receptacles using connecting pins with heads and keyhole openings arranged in the leg receptacles. Keyhole openings are openings that have a larger diameter and then an elongated hole with a smaller width. For assembly, the heads of the connecting pins are inserted into the larger diameter section of the keyhole opening and moved towards the narrower part of the keyhole opening so that the head prevents it from slipping out to the side. In this way, simple, quick and tool-free assembly and disassembly of the frame legs and, if necessary, other components attached in this way are advantageously possible.

According to a further preferred embodiment of the invention, it is provided that the individual parts are arranged within troughs of the grill that can be connected to closures. The lower pan is preferably the ash pan with the closures arranged on it.

The closures are designed as snap closures. The ember pan is located inside the ash pan. The storage tray serves as a cover and closure. Because all components of the grill are arranged within the case formed by the tubs and which can be closed with the snap fasteners, the complete grill can advantageously be transported and stored in a space-saving and clean manner.

According to a further preferred embodiment of the invention, it is provided that, for space-saving storage, the components have openings or recesses where the components placed opposite one another are provided with pins, hooks or other protruding elements. The protruding elements thus protrude into the openings and thus enable gaps between the components, such as in particular the frame legs, the side parts, the frame connectors and the shielding plates, to be avoided. Openings that are necessary or useful for the assembly and/or function of the grill are preferably used. By avoiding gaps between the components, the grill can be stored in a space-saving manner.

The invention further relates to an ember pan for a grill. According to the invention, expansion slots are arranged in the bottom surface element of the ember pan, with H-shaped slots offset from one another and one inside the other being arranged in a preferred of many possible embodiments. These slots advantageously serve to segment the bottom surface element of the ember pan and thus enable thermal expansion due to the glowing fuel, in particular the charcoal, and accordingly avoid curvatures in the bottom. At the same time, the slots serve to supply combustion air.

According to an advantageous development of the invention, it is provided that at least in two opposite corners of the ember pan, bores with slots extending radially therefrom are arranged, with angled ember pan holders designed with an insertion section being able to be inserted into the bores. The insertion section is accordingly designed to have slots corresponding to the bores. In order to secure the holders against slipping out, they are twisted slightly after insertion so that the orientation of the insertion sections no longer corresponds to the orientation of the slots. The holders thus advantageously enable the removal of a hot ember pan.

All figures show a grill 10 according to the invention or its individual parts in perspective views. In some illustrations the individual parts are only partially shown. Within all figures, the same reference numbers are used for the same components, although components that have already been presented may not be discussed again in each figure - based on the reference numbers.

In 1 a disassembled grill 10 packaged between a base pan 56 and a lid 52 is shown in the fully packaged assembled state. The fully assembled grill 10 is in the unpacked assembled state or in the state of use 17 shown.

At the in 17 The grill shown is a standing grill that can also be used as a table grill, as will be explained later.

Lid handles 54 are attached to the lid 52. The base pan 56 is releasably connected to the lid 52 by means of snap fasteners 50 attached to the side of the base pan 56. The space-savingly packaged Grill 10 is easy to transport and store.

The floor pan 56 also serves as an ash pan, as will become clear.

The 2 shows the in 1 Grill 10 shown and disassembled in an unpacking step with the lid 52 removed from the base pan 56 and the storage plate 60 removed. This makes a grate 20 and an adjusting rod 38 placed laterally in the base pan 56 as well as a storage plate 60 arranged between the cover 52 and the grate 20 visible.

After the unpacking step, removing the grid 20 and the storage tray 60 is how 3 shows the ember pan 22 underneath visible, with the ember pan 22 in 3 is arranged with its underside, which is formed in the state of use, facing upwards.

In a preferred embodiment of various possible embodiments, the ember pan 22 is provided with H-shaped slots that are offset from one another and project into one another, which serve as expansion slots 24. This prevents the ember pan 22 from warping and bulging when the glowing charcoal is in the ember pan 22.

In at least two or preferably in all four corners of the ember pan 22, as in 4 shown, holes are arranged with slots 90 extending therefrom. In 3 one of two ember tray holders 96 is shown, each of which has an insertion section 94 corresponding to the holes with the slots 90.

How 4 clarified, the insertion section 94 of the ember pan holder 96 can be inserted into the holes with slots 90 of the ember pan 22 and secured against slipping out by twisting.

This means that the ember pan holder 96 is locked in the hole with the slot 90 and thus in the ember pan 22. Since the holes with slots 90 extending therefrom are arranged directly in the corners of the ember pan 22, the ember pan holder 96 lies on the angled side sections of the ember pan 22 on. This ensures that the ember pan holder 96 is aligned perpendicular to the ember pan 22 above the insertion section 94.

Thus, a still hot ember pan 22 can advantageously be removed and moved by means of the two ember pan holders 96 when the grill 10 is in use.

In 5 is the base pan 56 of the grill 3 shown again with the components still inside, with the ember pan 22 having already been removed in a further unpacking step.

In the floor pan 56, two short side parts 12 are shown with their visible inside.

In the short side parts 12 with the two angled side sections 15 there are axially rotatable torsion bars 30 (see above 7C ) stored. Ember pan pivot levers 32 designed as U-shaped brackets are fastened to the torsion bars 30 and are hereinafter referred to as ember pan pivot levers. The oppositely extending torsion bar levers 34, which are guided through the short side parts 12 in the assembled state, are preferably arranged in the middle of the torsion bars 30.

In a preferred embodiment of the invention, the torsion bar levers 34 are designed as lever axes with ball heads arranged at the ends.

The torsion bars 30, the ember pan pivot levers 32 and torsion bar levers 34 together form, as kinematic minimum components 30, 32, 34, an adjusting device according to the invention for adjusting the height of the ember pan 22, as also (compare in advance) in 12 is clearly visible.

A movement of one of the torsion bar levers 34 causes the ember pan 22 to be raised or lowered on each side of the ember pan 22, starting from an imaginary starting position (center position) of the torsion bar lever 34. According to the invention, each torsion bar lever 34 is connected to an adjusting lever 36 for simple and convenient operation is in turn connected to the adjusting rod 38, as will be explained below.

Above and below the short side parts 12 are according 5 So-called first frame connectors 74 are inserted in the floor pan 56.

The 6 shows an outside of the already in 5 shown short side part 12. The torsion bar lever 34, which is guided in the assembled state through a through opening 26 with a recess in the short side part 12, thus enables the torsion bar 30 arranged on the opposite side of the short side part 12 to be rotated from the outside of the grill 10 in a certain predetermined angle of rotation.

On the underside of the short side parts 12 there are short frame legs 17 which are used for a table grill without long frame legs 16. The short frame legs 17 are advantageously provided with leg receptacles, which are used to attach long frame legs 16 for a standing grill (compare in advance for clarity). 8th and 9 ) are trained and serve.

The 7A shows, in addition to the other components, in particular the adjusting lever 36 arranged on the outside of the short side part 12 in the assembled state in a side view. During assembly, the fork-shaped end of the adjusting lever 36 is inserted onto the pin of the adjusting lever bearing 48 and then pivoted parallel to the short side part 12, after which the ball head of the Torsion bar lever 34 is inserted through the push-through opening in the adjusting lever 36.

The 7B shows, in addition to the other components, the short side part 12 with torsion bar lever 34 and adjusting lever 36 with the adjusting rod 38 in a side view. The short side part 12 with the adjusting lever 36 is shown in a view obliquely from above, with the adjusting lever 36 with the adjusting rod 38 also being shown.

The 7C shows, in addition to the other components, an excerpt from the 7B in an enlarged view obliquely from above, with the torsion bar lever 34, the adjusting lever 36 and the adjusting rod 38 being shown, the components of the inner adjustment kinematics 30, 32, 34 according to the invention and the outer adjustment kinematics 36, 38 according to the invention and their push-through connection 37 being well connected can be seen.

Below are the 7A , 7B and 7C described in a synopsis.

As in 5 and 6 The torsion bar 30 is already shown (compare 7C ) a central component of the adjusting device 30, 32, 34 (internal kinematics) for adjusting the height of the ember tray 22.

When assembled, the torsion bar 30 is oriented horizontally parallel to the short side part 12 and is rotatably mounted in the angled side sections 15 of the short side part 12.

The axis of rotation 30A of the torsion bar 30 accordingly runs parallel to the short side part 12. The torsion bar lever 34 is firmly connected to the torsion bar 30 and is led out of the grill 10 through an opening in the short side part 12, the torsion bar lever 34 being arranged orthogonally oriented to the torsion bar 30 .

Furthermore, the torsion bar 30 is connected to the ember pan pivot levers 32, which are designed to form a U-shaped bracket. The ember pan pivot levers 32 are oriented essentially horizontally in the starting position (middle position) and extend in the opposite direction with respect to the torsion bar lever 34 and are arranged above the floor pan 56. The ember pan pivot levers 32 are also arranged orthogonally to the torsion bar 30.

The adjusting lever 36 (external kinematics), which is oriented parallel to the short side part 12, is mounted in an adjusting lever bearing 48 designed as a pin and a head, the adjusting lever bearing 48 being arranged in the short side part 12. A pivot axis 36A of the adjusting lever 36 runs orthogonally to the longitudinal axis in the longitudinal extension of the adjusting lever 36 and is designed as a U-shaped fork. Starting from the starting position, the adjusting lever 36 can pivot up and down in the vertical direction about the pivot axis 36A (see arrows in 7B) be moved.

In the starting position, the torsion bar lever 34 is preferably oriented horizontally, so that the adjusting lever 36 can be plugged in to realize the push-through connection 37. The push-through connection 37 is realized in that the push-through opening is provided in the adjusting lever 36, through which the torsion bar lever 34 can be inserted with its ball head, so that the center of the ball head in the assembled state is arranged exactly in the middle of the adjusting lever 36.

According to the invention, the end of the torsion bar lever 34 leading into the adjusting lever 36, which is reversibly inserted into the push-through opening of the adjusting lever 36 during assembly, is designed as a ball head, with the axis of the torsion bar lever 34 resting in the push-through opening with little play in the assembled state.

The adjusting lever 36 is thus movably connected to the torsion bar lever 34 through the push-through connection 37. Accordingly, in the assembled state, when the adjusting lever 36 moves up and down about the adjusting lever bearing axis 48A of the adjusting lever bearing 48, the torsion bar lever 34 will be moved, although the longitudinal axis of the torsion bar lever 34 and the longitudinal axis of the adjusting lever 36 are arranged with different orientations in terms of their direction in the assembled state.

When using the adjusting lever 36, the fork-shaped end of the adjusting lever 36 slides or moves slightly in a linear direction relative to the adjusting lever bearing 48, that is, in the longitudinal direction of the adjusting lever 36.

According to the invention, the movement of the adjusting lever 36 moves the torsion bar lever 34 and thus also the torsion bar 30 with the ember pan pivot levers 32 or the U-shaped bracket attached to it, which thus also experiences the desired up and down movement.

The adjusting lever 36 or both adjusting levers 36 are each arranged on the side of the short side parts 12 and are preferably designed to be cranked at the ends and are each provided with a bore 39 on the side opposite the adjusting lever bearing 48, which serves to fasten the adjusting rod 38 on both sides (see 15 , 16 , 17 ).

In order to make the installation and operation of the height adjustment device of the ember tray 22 more comfortable enable, the adjusting levers 36 arranged on both sides of the short side parts 12 of the grill 10 are connected to one another by the adjusting rod 38 by means of a knurled screw 78 (see 7B , compare in advance too 13 and 17 ).

Starting from the starting position mentioned (middle position of the adjusting lever 36 and middle position of the ember pan 22), when the adjusting lever 36 or the adjusting rod 38 is depressed, it is ensured that the ember pan pivot lever 32, that is, the U-shaped bracket, and thus the ember pan 22 arranged thereon, are raised becomes.

To lower the ember pan 22, the adjusting rod 38 and thus the adjusting lever 36 are raised accordingly.

Since the ember pan 22 rests on the two ember pan pivot levers 32, in particular the U-shaped brackets, according to the invention it can be raised or lowered overall or raised or lowered on one side with the movement of the adjusting lever 36.

By means of the adjusting levers 36 arranged on both sides, different heights can advantageously be preset on both sides, with the adjusting rod 38 being arranged, for example, at an angle relative to an imaginary horizontal, which also causes the ember pan 22 in the grill 10 to be in an inclined position in one direction or the other is arranged.

In order to limit the range of motion of the adjusting lever 36, it is equipped with an inwardly projecting limiting pin 44 (see 7C ), which, when assembled, is located in an arcuate boundary slot 46 (see.) made in the short side part 12 7A , 7B) the short side parts 12 is movably arranged.

The length of the limiting slot 46 accordingly limits the mobility of the respective adjusting lever 36 upwards or downwards from the starting position.

In addition, in order to lock the adjusting lever 36 and thus the height of the ember pan 22 (not shown), it is provided that a locking pin 40, which also projects inwards, is arranged on the adjusting lever 36. The locking pin 40, which is designed with a tip, can be locked in recesses 42 which are inserted into the short side part 12 at short intervals.

The latching pin 40 is designed with a thread so that it can be adjusted so that the latching function in the circular arc-shaped recesses 42 (see 7A) is advantageous in the short side part 12.

Because the two adjusting levers 36 are connected to one another in the assembled state by means of the adjusting rod 38, they are arranged at a defined distance from one another, so that a defined pressure of the latching pins 40 in the recesses 42 can be realized.

The latching function is made possible by the flexibility of the side parts 12 and the adjusting lever 36. Likewise, the latching function can be realized by a spring (not shown) which is conveniently arranged on the latching pin 40.

The latching function is therefore a combination of positive and non-positive connection of the latching pin 40 with the recesses 42 in the side part 12.

The 8th shows the attachment of the floor pan 56 before attachment by means of the snap fasteners 50 of the recesses made in the long side part 14.

The angled design of the short side part 12 and, as a continuation, the short frame legs 17 (for the table grill) with the leg receptacles arranged therein for fastening the long frame legs 16 (for the standing grill), as with regard to the assembly in the Assembly state in the following 9 is shown.

The 9 shows the short side part 12 from the inside and from its underside. On the leg shots (in 9 only one leg holder is shown) of the short side part 12, each with a head connecting pins 70 are attached.

Openings designated as keyhole openings 80 are arranged in the long frame legs 16, corresponding to the connecting pins 70. The keyhole openings 80 each include a larger opening, such as a bore, and a smaller width slot extending radially from the bore. The width of the slot corresponds to the diameter of the connecting pin 70.

During assembly, the keyhole opening 80 arranged in the long frame leg 16 is basically inserted over the head onto the connecting pin 70 on the bore side and the long frame leg 16 is moved in this way (see below Arrow) that the connecting pin 70 reaches the area of the narrower slot. In this position, the head of the connecting pin 70 can no longer be released from the keyhole opening 80, so that a connection that is fixed after assembly and can be released again without tools can advantageously be formed, through which a table grill can be reversibly converted into a stand grill .

First, the lower keyhole opening 80 is pushed onto the lower connecting pin 70 (lower arrow), with this keyhole opening 80 being designed to be open downwards. Subsequently, the long frame leg 16 is rotated/pivoted to the right (upper arrow), so that the upper keyhole opening 80 can be pushed or has been pushed over the head of the upper connecting pin 70.

This means that the long frame leg 16 is connected to the leg holder of the short frame leg 17 of the short side part 12. Due to the inclined position of the frame legs 16 in the assembled state, which is achieved due to the connection designed in this way, it is avoided that the connection comes loose automatically. The solution shown advantageously enables tool-free and quick assembly and disassembly of the frame legs 16, 17 and at the same time a high level of stability of the grill 10.

The 10 shows two different locking plates 72, each with two recesses 73 for receiving a connecting pin 70 in an annular groove 71 (see 11 ).

Especially the one in 10 The lower locking plate 72 shown is intended to be used on the one hand as a second frame connector 76 and on the other hand serves as a support for the storage plate 60 (see 2 and in advance 17 ).

In 11 the connection of a carrying handle 58 to the frame legs 16 is shown.

The ends of the carrying handle 58 are each designed as connecting pins 70 provided with an annular groove and inserted through holes arranged in the frame legs 16.

To fix the carrying handle 58 in the frame legs 16, the recesses 73 of the locking plate 72 are inserted into the annular grooves 71 of the connecting pins 70 on the opposite side. The carrying handle 58 is thus secured against automatic loosening.

In 12 A partially assembled stand grill is shown. Ember pan 22 and grate 20 are not yet installed here. In the angled side sections 15 of the short side parts 12, the torsion bars 30 with the ember pan pivot levers 32 extending orthogonally inwards and the torsion bar levers 34 extending orthogonally outwards are arranged. Due to the movement of the torsion bar levers 34, the ember pan pivot levers 32, which are designed as U-shaped brackets, raise and lower, whereby the ember pan placed on it (in 12 not shown) can be varied in height.

The support sections 18 arranged on the top of the angled side sections 15 serve to support the grate 20.

In the 13A , 13B an area of the inside of the stand grill is shown in an enlarged view. The difference 13A and 13B is that in 13B A short shielding plate 64 is already arranged on the short side part 12 and a long shielding plate 66 is arranged on the long side part 14, which are located in 13A still in a position before assembly.

The shielding plates 64, 66 are fastened by means of connecting pins 70, which are connected to the side parts 12, 14.

The connecting pins 70 are provided with an annular groove into which the shielding plates 64, 66 provided with a keyhole opening 80 are hung, the principle being described in the description 9 is already described.

The keyhole openings 80 correspond to the connecting pins 70 and the annular grooves 71 arranged therein. The shielding plates 64, 66 with the keyhole openings can be plugged onto the connecting pins 70 and then moved towards the narrower part of the respective keyhole opening 80.

The shielding plates 64, 66 enable the largest part of the torsion bar 30 and the side parts 12, 14 to be protectively covered.

The 14A , 14B show the frame legs 16 with the locking plate 72 installed (compare 13B) and the second frame connectors 76.

Connecting pins 70 with annular grooves 71 are in turn attached to the second frame connector 76. Keyhole openings 80 corresponding to the connecting pins 70 with annular groove 71 are also made in the frame legs 16. The connecting pins 70 can each be inserted into the keyhole opening 80 with the annular grooves 71 and to the narrower part of the keyhole opening 80 be moved there. This advantageously creates a positive connection simply, quickly and without tools.

The long side parts 14 are connected to the short side parts 12 (compare 8th ) in the same way that has already been described several times. The second, long side parts 14 can be suspended by means of connecting pins 70 in keyhole openings which are arranged in the first side parts 12.

The 15 shows two frame legs 16 now with the second frame connector 76 installed (compare 14 ) and first frame connector 74. The first frame connector 74 is screwed onto the second frame connector 76 by means of a fastening screw 78, in particular with knurled screws. Due to the reduced distance, the cover 52 (see 17 ) can be arranged on the first frame connector 74 as a storage option when the stand grill is assembled.

In 16 will again refer to the short side parts 12, on which locking plates 72 and carrying handles 58 can also be arranged via connecting pins with annular groove 70 in openings provided for this purpose.

In 17 A fully assembled stand grill is shown in its assembled state.

The two adjusting levers 36 are also connected to one another by the adjusting rod 38 by means of fastening screws, in particular also knurled screws 78. By screwing the adjusting levers 36 to the adjusting rod 38, the positioning of the adjusting levers 36 is achieved parallel to the short side parts 12, with the contact pressure of the locking pins 40 in the recesses 42 (see in particular 7A , 7B and 7C ) is effected in the side parts 12 and is adjustable.

In contrast to this, 12 the grate 20, including the ember pan 22, the base pan 56 and the storage tray 60 are arranged, the ember pan 22 being partially covered by the grate 20. In the assembled state, as explained, the ember pan 22 rests below the grate 20 on the ember pan pivot levers 32.

Starting from a starting position, an actuation of the adjusting rod 38 can be transmitted via the adjusting levers 36 to the torsion bar 30, which independently raises and lowers the ember pan pivot levers 32, which are designed as brackets, on both sides of the grill 10, as is illustrated by the arrows on the adjusting rod 38 .

Pressing downwards, similar to operating a pedal, leads to the raising of the ember tray 22 and thus to accelerating the grilling process, while pulling upwards, similar to operating a pedal in the opposite direction, lowers the ember tray 22 on one or both sides so that intuitive, easy operation is achieved. The user can advantageously choose whether he wants to raise or lower one or both sides of the ember pan 22.

The lid 52 and the storage tray 60 serve, for example, as a shelf for tools and grilled food, with the trough-like lid 52 together with the base tray 56 (compare 11 and 12 ) advantageously serves as outer packaging for the grill 10, in particular the table grill and the stand grill.

Finally, in relation to 17 also mentioned that in the storage tray 60 (see also 2 ), that is, on its inside, according to 17 In the assembled state, instructions for assembly are arranged on its underside, it being preferred according to the invention that the instructions are either preferably lasered into the material of the storage tray 60 using a 3D laser engraving process or preferably as a digital print glued onto the inside -Foil is pasted.
