Description

Foldable grill

The invention relates to a grill according to the preamble of claim 1.

Especially with grills that are used on a terrace or in the garden or that are to be taken along on trips, such as a camping grill, it is desirable to be able to fold the grill up so that it can be stored in a space-saving manner when not in use or when traveling.

For this purpose, a grill is known whose legs can be folded against each other, namely the legs on one side against the legs on the other side. The legs are made of square tubes and two legs belonging to one side are rigidly connected to each other by a horizontal strut, so that they form an H- shaped pivoting or folding unit. In the folded position, two square tubes forming the legs stand one above the other, which results in a considerable height of the grill when folded. In addition, when folded, the arrangement is rather unsightly because of the folded legs. Sinking the legs into the frame of the grill is not provided for in this design and is also hardly possible, since the frame would have to be made considerably high, which would result in the grill being much heavier.

which is also undesirable. In addition, the design of the legs in the form of square tubes also leads to a considerable weight of the grill.

The invention is based on the object of designing a grill device of the type described at the beginning in such a way that, while ensuring a low weight of the grill device, a small and practical arrangement is achieved in its folded state.

This object is achieved by the characterizing features ' ■' of claim 1.

In the design according to the invention, the legs consist of molded parts that are preferably open at the top when folded, which are thus shell-shaped and can be placed inside one another in the folded state. This achieves both the desired reduction in size and

in the folded state and an attractive design and a pleasant appearance of the grill are achieved. The desired weight reduction results from the elimination of walls of the U-, L- or bowl-shaped legs according to the invention (') 25.

The features contained in claims 3 to 8 lead to simple and practical designs, which also enable simple and inexpensive production. It is recommended that the legs be formed from sheet metal over as large an area as possible, as this significantly increases the section modulus of the legs. In addition, in a design according to claim 7, the legs form an underside closure for the frame when folded, so that a light load-bearing

or transportable grill is created, the interior of which is protected by the folded-in walls.

The designs according to claims 8 to 16 enable the grill to be closed at the top, whereby this side also provides protection against moisture or dirt or even a visual barrier.

As with the design of the legs, a box-shaped profile of the

lid or the lid parts, which allows for easy Ways to achieve a dimensionally stable design.

The design according to claim 12 improves the practicality of the grill, in particular when a frame with a rectangular cross-section is used and/or the lid or the lid parts form storage areas when opened.

The features contained in claim 13 significantly increase the strength of the legs or the lid or the parts in the edge area by additional stiffening. The latter is particularly important for the lower ends of the legs, where a stable design is desired.

In an embodiment according to claim 14, the associated wall of the frame can be used in a simple manner as a support for the lid or the lid parts in the essentially 180° opened state, so that the lid or the coverHeHe form work or storage surfaces without the need for special support of the lid or the lid parts.

3g By means of the features contained in claims 15 and 16

&iacgr;:; '! &udigr;&igr;

Feature?&pgr; 1is the securing of the relevant parts in the folded position guaranteed

An embodiment according to claim 17 leads to additional fastening options for barbecue cutlery or the like. -

(Gr111-H1Ifmittel), whereby recesses arranged on the upper edge of the frame for receiving grill skewers can be used to accommodate the fastening projections in the folded-in state of the lid or the lid part (claim 19). The fastening projections can also simultaneously form fastening latches which, with latch parts arranged movably on the frame, for example, (< e.g. pivotable latch pockets), enable the lid or the lid parts or the legs to be locked (claim 20).

The embodiments according to claims 22 and 23 result in a case-like arrangement in the folded state of the grill, in which the ember box is accommodated in a space-saving way and which can be easily and comfortably carried.

The solution features contained in claims 24 to 28 contribute to stabilizing the relevant sub-areas (25) of the grill, whereby weight can be saved by making the actual supporting parts of the grill weaker or thinner. This also saves material and weight. The stabilization is particularly recommended for

a material of the frame and/or legs or ,

of the lid or the cover parts made of less solid material. If aluminum is used, the weight of the grill can be further reduced. If brass is used for the fittings, the result is

3g is not only used in die-cast

fittings, but also a fundamentally stable arrangement, which is also characterized by a pleasant appearance.

The further developments according to claims 29 and 30 relate to improvements in the area of the ember box. A height adjustment is therefore particularly suitable because it can also be used to set the ember box so high that it is in the area of the frame iö, after which the legs can be folded up without interference.

' The fittings can be attached in a simple manner by rivets according to claim 34.

The invention is explained in more detail below using exemplary embodiments shown in drawings. It shows:

The grill device, generally designated 1, has a horizontally extending frame 2 of rectangular or square cross-section, which is formed by essentially vertically extending frame walls 3, and which, with a grill grate 4 placed on its upper side on brackets shown in outline, forms a grill table, the broad side of which is the operating side.

The grill has legs 5,6 that can be folded in or out, which are hinged to the underside of the frame 2 in the area of the narrow sides of the frame 2 and can therefore be folded in or out against each other. The legs 5,6 extend approximately over the entire width of the narrow sides, creating standing walls.

The legs 5,6 are U-shaped in horizontal cross-section and are preferably bent in one piece from a sheet metal panel or deep-drawn in a box or tub shape, with the hollow sides facing upwards in the unfolded position. The arrangement is such that the legs 5,6 are placed inside one another in a box or bowl shape when folded in.

This means that the inner leg 5 in the folded state has a greater width b than the width b of the outer leg 6 in the folded state, so that the 5 stiffening legs 9 extending transversely to the web walls 8, which can also be arranged at the lower and/or upper end of the legs 5,6 in the horizontal extension, lie next to one another in the folded state. It is easy to arrange the legs 5,6 in such a way that in the pivoted-in position they are at least partially sunk into the frame 2, or the leg 5 to be folded in first. This can be achieved in a simple way by the legs 5,6 being positioned between the web walls 3 of the frame 2, the width b,b being adjusted accordingly. In the present embodiment, the height h (Fig. 2) of the Ecine 5,6 is matched to the length of the broad side or operating side BS of the frame 2, so that in the folded-in position of the leg 6 to be swung in last, the underside of the frame 2 is essentially closed.

The lower end of the legs 5,6 can have a recess 11 in the middle, so that four feet 12 are formed at the lower corners of the legs 5,6.

In the standing position the legs 5,6 are slightly

inclined outwards. The web walls 8 of the legs 5,6 can be supported on the inner lower edge of the associated frame wall 3 of the frame 2. This can be done in a simple manner by appropriately measuring the distance c of the relevant pivot axis 7 from the associated narrow side. In the present embodiment, the legs 5,6 are supported in the standing position by two struts 13 arranged transversely to one another (only in

Fig· 6) on the back of the grill

1, which are releasably attached by screws or other fastening elements to the stiffening legs 9 and to the frame wall 3 of the frame 2 located above them.

The upper side of the frame 2 can be optionally closed by two cover parts 14,15, which also pivot about pivot axes 16 \ in the area of the narrow sides of the frame 2.

are pivotally attached to the frame, whereby the also t with angled or deep-drawn stiffening legs

17 cover parts 14, 15 made of sheet metal in the form of a box or shell are arranged between the associated, opposite frame walls 3 of the frame 2. This also makes it possible to arrange the cover parts 14, 15 optionally recessed in the frame 2 in the folded-in position. In the present embodiment, the cover parts 14, 15 protrude slightly from the upper edge of the frame 2 in the folded-in position, which can be seen in Fig. 2. The stiffening legs 17 point downwards so that the upper side of the cover parts 14, 15 is flat.

The pivot axes 16 also have a distance d from the narrow sides of the frame 2, which makes it possible -

^1st » ^the narrow-sided frame walls 3 as supports

18 for the cover plate 14,15, so that the cover plate 14,15 is supported in the horizontal, opened position. If the pivot axis^ 16 is arranged a distance e lower than the upper edge of the frame 2, then a recess 19 on the upper edges of the relevant frame walls 3 is required for the above-described support, as shown in Figs. 1 and 2. In the opened position, the cover plate 14,15 form a widening of the grill table or storage and work surfaces 2i, whereby the 1n of this

Position upward-pointing stiffening legs 17 form advantageous edge boundaries. The length 1 of the cover parts 14,15 corresponds approximately to half the length of the operating side BS of the frame 2, so that the free

Ends of the cover parts 14,15 in the folded state

while maintaining a small gap 22.

An ember box 23 can be hung in the frame 2 in different height positions. For this purpose, brackets 24 with a rectangular or square peripheral shape are used with several horizontally extending rods 25 that are spaced apart, which ensure the height-adjustable arrangement of the ember box 23 by being held on support hooks 26 that protrude from the inside of the narrow frame walls 3 and are only shown in Fig. 4. The brackets 24 thus extend transversely to the operating side and are mounted on the ember box 23 so that they can pivot towards or away from each other, which makes it easy to hang and unhook the support hooks 26. In order to do this,

To enable this, there is a free space 27 between the grill grate 4 and the narrow side frame walls 3, through which the brackets 24 extend upwards from the ember box 23. In Fig. 4, the grill grate 4 is not shown for the sake of clarity ( 25).

On one of the two wide sides of the frame 2, preferably on the operating side BS, a support bracket 28 for carrying the grill in the folded position is attached, preferably in the middle position of the associated frame wall 3. This makes it possible to carry the grill 1 in a suitcase shape as shown in Fig. 3. To secure the legs 5,6 and/or the lid parts 14,15 in the folded position, various

Securing elements are possible. In Fig. 5 an advantageous Possibility shown with a safety element,

which can be formed in one piece on the associated leg 5, 6 or cover part 14, 15 or on the frame 2. This securing part is formed by a rounded, bulge-shaped bend 29, which is attached to the stiffening leg 17 of the cover part 15 as shown in Fig. 5. The securing is achieved here by friction of the bend 29 with the inner surface of the frame 2.

The embodiment according to Fig. 6 to 9, in which

a (iiut box 23 is not shown for reasons of simplification is basically the same as the one described above

Example of implementation. In the following, therefore, only

the design differences are described. 15

On at least one of the cover parts 14, 15, preferably on both, an attachment piece 31 is arranged, also preferably on the operating side B, which in the present embodiment is formed by a button- or mushroom-shaped hanger, which is attached to the stiffening leg 17 in approximately the middle position. Auxiliary parts for the grill, such as grill cutlery, can be hung on the attachment piece 31 in an easy-to-use manner when the grill is opened. In addition,

() 25 the attachment piece 31 represents a handle with which the relevant cover part 14, 15 can be opened and closed in a way that is easy to handle. Depending on the arrangement of the cover part 14, 15 in a more or less recessed position, a recess 32 is required on the upper edge of the frame 2, into which the attachment piece 31 can be inserted. Such a recess 32 can also be used to accommodate size splices (not shown), which are placed on the upper side of the frame and are secured in the recess 32 against slipping sideways. It is advantageous to also have a recess 32 on the rear wall of the frame.

3 a recess 32 is provided. In the present embodiment, there are three pairs of recesses 32, of which the two outer ones are provided with the attachment pieces

31 correspond to the cover parts 14,15 and the

additional central recess 33 serves solely to accommodate a barbecue skewer.

In the present embodiment, the attachment piece(s) 31 also serve to lock the cover parts 14,15 in the folded-in position. For this purpose, the front frame wall 3 is provided below the recesses

32, a hook-shaped latch 34 is rotatably attached, which can be rotated in such a way that its hook part 35 engages over the associated extension piece 31 and thereby preferably exerts a clamping pressure on the latter, whereby the latch is secured in this locking position. The cover parts 14, 15 are assigned supports (not shown) on the upper edge or on the inner sides of the frame 2, on which they rest in the folded-in position. Such a support can be the grill grate 4, or the supports 20 of the grill grate 4 shown in Fig. 1 and 4 and attached to the inner sides of the wide frame walls 3 can also serve to support the cover parts 14, 15 in the folded-in position.

For legs 5,6 a similar locking mechanism is

Here, the last folding part is

In all embodiments, the frame 2 has a height H such that in the folded-in position of the cover plate 14, 15 and the legs 5, 6, the ember box 23 with its height k lies between the legs 5, 6 and the

IQ lid plate 14.15 or the grill grate 4

can be folded into the ember box 23, resulting in a packaging unit that is easy to handle. The arrangement is such that the brackets 24 also find space between the ember box 23 and the grill grate 4 or the lid parts 14, 15 when folded into the ember box 23.

In the embodiment according to Fig. 6 to 9, zones on individual parts of the grill device 1 that are subject to a higher

are subject to increased loads through fittings, the

can be placed on top or underneath. Such load zones are particularly in the area of the retaining bracket 28, in the area of the joints generally designated 38 and 39 for the cover parts 14, 15 and for the legs 5, 6 and/or at the support points of the legs 5, 6. The arrangement of the fittings makes it possible to make the associated walls of the cover parts 14, 15, the frame walls 3 and/or the legs 5, 6 thinner and thus save weight.

In the area of the joints 38,39, the frame walls 3 are reinforced at the corners of the frame 2 by reinforcement angle pieces 41 placed on the outside, on which the joints 38,39 are formed in that the joint axes 16 also pass through the angle pieces 41.

3g present embodiment, the joints 39

for the cover parts 14,15 are arranged on upwardly projecting projections 42 of the angle pieces 41, namely in such a way that the lower edge of the cover part 14,15 in the folded-in position is approximately flush with the upper edge of the frame 2 and/or the grill grate 4 1n. In such a configuration, the upper edge

43 of the narrow-sided frame walls 3 as supports 18

for the cover parts 14, 15 in their unfolded position, without the need for a recess 19 according to the embodiment according to Fig. 1 and 2. This means that in the embodiment according to Fig. 6 to 9 the cover parts 14, 15 cannot be lowered into the frame 2.

A further reinforcing angle piece 44 is provided in the attached position for the corners of the cover parts 14, 15 in the area of their joints 39. The angle piece

44 preferably has three reinforcing walls for the

to be reinforced (stiffening legs 17, cover wall 45), whereby the hinge axis 16 passes through the vertical reinforcement leg of the angle piece 44 adjacent to ^the projection 42. The detail VIII shows the arrangement with the cover part 14 folded in.

A similar or comparable reinforcing angle piece (25 46) is also provided on the free corners of the legs 5,6 in order to reinforce their corner areas, see detail VIV. These angle pieces 46, which reinforce the corners of the legs 5,6 preferably on three sides, are also preferably attached.
30

In the present embodiment, an additional stiffening in the area of the joints 39 and the free corners of the legs 5,6 consists in the stiffening legs 3g 17 running transversely to the operating side BS on the cover parts 14,15 and/or the longitudinal

· * t

The stiffening legs 9 extending from the base at the free ends of the legs 5 do not extend at right angles to the cover walls 45 or web walls 8 of the legs 5,6, but are curved. The angle pieces 44,46 are adapted accordingly, i.e. their respective walls are also curved.

A further reinforcement is provided in the area of the retaining bracket 28 in the form of a reinforcement plate 47, which is placed on the front frame wall 3 and to which the U-shaped retaining bracket 28 is attached.

All of the reinforcement parts described above can be riveted in a simple and advantageous manner, which is indicated in the drawing by the representation of rivet heads.

Another way to reduce the weight of the grill is to make essential individual parts out of aluminum. It is recommended to make the fittings 41, 44, 46 and 47 out of a stronger material, especially brass or bronze, which allows for a stable construction and at the same time improves the appearance of the grill 1 ( ) 25, especially if the other parts of the grill 1 are made in a dark or black color.

For similar reasons, in the present 3Q embodiment, the brackets 24 are also made of brass or bronze in their upper area, where they are gripped by the operator. For this purpose, the bracket 24 is made of two parts, whereby the upper U-shaped bracket part, designated 48 in Fig. 10, is made of brass 3g or bronze and in the area of the butt joint 49

15

the tenons or rivets are connected to the vertical rods 50 of the bracket 24.
