Abstract

The apparatus according to the invention for grilling or roasting food over a heat source, having at least one spit (4) for accommodating the food, has a frame (1) which encloses, at least in part, an opening plane. This frame (1) contains mounts (12) for the insertion of the spit (4) parallel to the opening plane of the frame (1), and formed on at least one side of the frame (1) is an all-round carry-along element (7) in which a carry-along plate (6), which is arranged on the spit (4), engages, and the movement of the carry-along element (7) thus causes the carry-along plate (6), and thus the spit (4), to rotate. It is thus readily possible for the spit (4) to be easily inserted into, and lifted out of, the mounts of the frame (1) without it having to be separately coupled to, or uncoupled from, a drive. It is also the case that the spit (4) is rotated automatically by the carry-along element (7) once it has been inserted into the frame (1). It is thus possible, on the one hand, for the food on the spit (4) to be grilled or roasted uniformly all the way round and, on the other hand, for the spit (4) to be removed from the heat source at any desired point in time simply by being lifted off.

Description

Device for grilling food

The present invention relates to a device for grilling food according to the preamble of claim 1 and a grill device according to the preamble of claim 14.

Usually grills have a horizontal or vertical hearth, which is operated either by coal or wood or gas burner has to generate the heat. In conventional open pan grills with horizontal hearth, a grill grate is arranged above the hearth, on which the food to be grilled is placed. In order to achieve the most regular possible heat effect on the food to be grilled, this must be turned regularly, also to prevent the food burns or even burns.

Often, the food to be cooked is also placed on a skewer, especially when the food to be cooked consists of a combination of several individual items to be cooked. When using small skewers, as they are often used for the portionwise, individual provision of grill food, which is located on the skewer grill food is also placed on the grill together with the skewer and regularly turned manually, for example, using a barbecue tongs. In this case, the problem usually occurs that by turning although the opposite sides of the food to be fried optimally roasted resp. can be grilled, the sides of the food, however, less the heat are exposed, and thus no completely homogeneous grill effect can be achieved.

For larger barbecue good individual long skewers are used, which can be used in side of the fireplace arranged shots. Such a skewer is usually used spanning the entire length of the hearth and can be rotated by hand, for example, with a arranged directly at one end of the skewer crank to grill the food. As another possibility, a motor, which is connected directly via a reduction gear with the skewer, are used to rotate the skewer regularly and a all-round regular roast resp. To ensure barbecue of the food. The disadvantage of this device is that the engine resp. the crank must be coupled to the skewer before the grilling process and must then be removed from this again before the grilled food can be further processed, for example, can be served. In particular, such a device is not suitable for the use of multiple skewers or for the use of small skewers with individually portioned grilled food.

The object of the present invention was to find a device that a simple, reliable grilling arranged on a skewer

Grill food allowed, with the skewer to easily position over the hearth and also to be removed again. This object is achieved according to the invention by a device having the features of claim 1. Further, preferred embodiments further result according to the invention from the features of the further claims 2 to 13.

The device according to the invention for grilling food to be grilled over a heat source with at least one skewer for holding the food to be grilled has a frame on which at least partially encloses an opening plane. In this context, recordings for inserting the skewer are formed parallel to the opening plane of the frame and it is formed on at least one side of the frame, a rotating driving element, in which a spit arranged driving plate engages and thus by the movement of the driving element driving plate and thus the skewer is put into a rotary motion. Thus, the spit can easily insert into the receptacles of the frame, respectively. lift it out again without having to be separately coupled or decoupled with a drive. The skewer is also rotated automatically after insertion into the frame of the driving element. Thus, on the one hand an all-round grilling of the grilled food mounted on the skewer can be achieved and on the other hand, the skewer can be easily removed by lifting and at any time from the heat source.

For example, the frame has at least one flat profile on which the entrainment element is arranged. The driving element is doing on one side of the flat profile arranged and is therefore easy to install and free access to the entrainment is guaranteed at all times.

Preferably, the flat profile is designed as a hollow profile, which has at its upper edge a preferably extending over the entire length of the profile opening. Thus, advantageously, the driving element can be arranged in the interior of the flat profile, whereby it is laterally protected against unintentional access and pollution and direct heat influence. Nevertheless, through the opening, the driving disc of the skewer can enter from above into the driving element and be set in rotating motion by the latter.

For example, at least a part of the cream is formed by means of rods, wherein in this part existing recordings are formed by U-shaped bends of the rods. For example, the part of the frame provided with the driving element opposite frame part may be formed from rods or tubes. The recordings for the skewer can then be easily realized by upwardly open, U-shaped bends.

For example, the frame is made of metal to ensure a long life of the device and to allow easy production. Of course, other, heat-resistant materials for the construction of the frame are also suitable.

For example, the driving plate is arranged at an end region of the skewer centric to the longitudinal axis of the skewer and has radially outward on the circumference protruding teeth. The driving plate can thus be formed, for example, as a flat toothed disc with a central opening for the passage of the end of the rod of the skewer. The rod of the skewer is thereby positively or non-positively connected to the driving disc, so that the rotational movement of the driving disc is transmitted to the skewer. The driving plate can advantageously be made of metal, or of another heat-resistant material, such as a heat-resistant plastic.

For example, the spit at one end of a handle made of a heat-insulating material, preferably made of wood or heat-resistant plastic. The handle is advantageously formed at the same end as the driving plate. Thus, the handle can be connected directly to the driving disc and the rod of the skewer in a correspondingly formed receptacle of the handle form-fitting inserted. Thus, for example, a number of bars can already be equipped with grilled food, and in each case connected to the grilling bars with the handle and placed on the frame. Of course, the skewer can also be designed as a firmly connected unit of rod, driving disc and handle. For example, the driving element is designed as a chain or band, preferably as a profile band. If the driving element is formed from circulating endless chain, formed on the driving plate teeth can easily engage in the interstices of the chain links and a simple and reliable drive of the skewer is guaranteed. A chain made of metal is also sufficiently robust for use directly next to the heat source and not prone to contamination. Alternatively, the use of a heat-resistant plastic profile belt is conceivable, which is provided on its outer side with ribs. Between these ribs also the teeth of the driving disc of the skewer can intervene and thus the skewer are driven. It is also conceivable to use a simple band provided with a rough surface. The driving plate would then also be equipped with a high roughness having circumferential surface which is brought into friction when placing the skewer on the frame with the tape.

For example, the entrainment element is operatively connected to a hand crank or a drive, preferably an electrically operated motor, in order to be set in circulating motion. In order to automate the rotational movement of the skewer, the use of a motor for driving the driving element is advantageously provided. Thus, for example, an electric motor can be used, which is connected via a reduction gear with the driving element. Conceivable, of course, is the manual drive of the driving element via a hand crank.

For example, the entrainment element is arranged inside the frame. Thus, the driving element against unwanted resp. unintentional interference from outside shielded and largely protected against contamination. Only for the driving disc of the skewer an opening in the frame is provided so that it can be brought into connection with the driving element.

For example, the receptacles are formed in the frame for the skewer as U-shaped, upwardly open slots, which are arranged perpendicularly extending in the wall of the frame. Through the upward opening is the insertion resp. Lifting the skewer from the shot simply guaranteed. The lower, rounded end of the slot serves as a simple storage of

Spiesses, which can be twisted without much resistance around its axis. Such slots can be advantageously simple and inexpensive form in the context.

By way of example, at least three receptacles arranged at the same distance from each other are formed along one side of the frame, and corresponding receptacles are formed perpendicularly thereto on the opposite side of the frame. The corresponding pairs of receptacles thus form a two-point storage for each spit. This can advantageously be used at least three or more skewers parallel to each other over the fireplace. Thus, the device according to the invention is advantageously suitable for the use of smaller, individually provided with Grillgut different Grilldauer skewers. At the same time, every single skewer can be brought over the hearth or removed from it at any time and independently of the other skewers or the drive optimal grilling results can be achieved for each individual skewer.

For example, connecting elements are formed on the underside of the frame in order to connect to the top of a fire pan of the heating source, preferably positive and / or non-positive. Thus, for example, the frame may have downwardly projecting pins or cams, which laterally reach the inside of the fire pan and thus position the frame immovably or optionally adjustable over the fire pan. For cleaning purposes or other uses of the fire pan, the frame can also be easily removed from the fire pan, for example, to be lifted. So that this does not occur unintentionally, further locking elements may be provided, which must first be solved before the frame can be removed from the fire pan.

The object is further achieved according to the invention by a grill with a device according to the invention, with a grill pan and fireplace arranged therein, in which the frame is connected directly to the grill pan or formed directly through the upper edge of the grill pan. The frame of the device according to the invention can for example be connected directly to the hearth, for example screwed or welded. The frame can also be formed directly from the upper part of the fire pan itself and thus practically consist of one piece resp. be directly integrated in it. For example, in such a grill, the hearth has a grate for receiving solid fuel such as wood or charcoal and / or gas powered fuel jets at the bottom and / or side wall. Thus, the grill can be operated as a conventional charcoal grill or provided with a gas connection. Of course, the use of other heat sources is conceivable, such as electric heat sources, especially in fixed installed grills.

For example, the grill pan is connected to a stand device, wherein the stand device preferably has rollers or wheels. This makes it possible to operate the grill independently of the location, has an optimal working height and can also be easily set aside when not in use.

It is clear to a person skilled in the art that not only a carrier element can be arranged on one side of the frame, but, for example, two carrier elements can be arranged parallel to one another on two parallel side walls of the frame. For example, these driving elements may have different driving speeds, so that different by appropriate placement of the skewer with contact the driving plate for one or the other driving element

Rotation speeds of the skewers can be achieved. Embodiments of the present invention will be explained in more detail below with reference to figures. Show it

1 shows the apparent view of a device according to the invention, mounted on an open horizontal grill;

2 shows the apparent view of an alternative embodiment of a device according to the invention;

3 shows the partial view of a flat profile of a frame according to the invention, designed as a hollow profile;

4 shows the longitudinal section through an inventive skewer with driving disc.

Fig. 5 is the front view of the skewer of Figure 4; and FIG. 6 shows the partial view of the deflection region of a carrier element, designed in the form of a chain.

In FIG. 1, the view of an embodiment of a device according to the invention is shown purely schematically. The frame 1 is placed on a grill pan 2, so that the opening plane of the frame comes to lie directly over the hearth 3 of the grill pan. In frame 2 here is a skewer 4 for receiving the food (not shown) mounted horizontally rotatable. The grill pan 2 is for example part of a conventional, by means of charcoal or gas burners operated, provided with horizontal hearth 3 grilling device.

The skewer 4 consists essentially of a straight lance-like main body, one end of which has a point and at the other end a handle 5 is arranged. For example, this handle 5 is made of wood or other heat-resistant and insulating material, while the main body is advantageously made of metal. The spit 4 now points even further in the area of

Handle 5 a perpendicular to the longitudinal axis of the skewer 4 stationary drive plate 6. This drive plate 6 has, for example, according to a gear on its periphery teeth 6 ', which engage in correspondingly shaped openings of a driving element 7. The

Driving element 7 is formed here, for example in the form of a chain, in the sectional openings of the teeth 6 'of the drive plate 6 engage.

The driving element 7 is designed as a guided around two pulleys 9, endlessly rotating element. The

Driving element 7 can thus be set in motion, for example, by rotating a hand crank 8 arranged on the axis of one of the deflection rollers 9. Thus, the drive plate 6 is rotated and thus turned the skewer 4 with the food to be grilled.

The frame 1 is formed as a U-shaped part with two opposite, parallel side walls 10 and 11. At the upper edge of these side walls 10 and 11 are spaced from each other a number of U-shaped Slits formed as receptacles 12 for the skewer 4. These recordings 12 form the storage for the skewer 4, which can be easily inserted from above into these receptacles 12 and also easily lifted out of it. According to the number of shots 12 along the side walls 10 respectively. 11 several skewers 4 can be operated parallel to each other over the hearth 3. Each skewer 4 can be placed individually on the frame 1 at any time or removed therefrom. Advantageously, all used in the frame 4 skewers are put together on the driving element in rotation, so that the hearth 3 can act regularly from all sides on the attached to the skewers 4 Grillgut and allows a regular grilling of the food. Advantageously, instead of the hand-operated crank 8, an automatic drive device can also be used, for example an electrically operated motor with an integrated reduction gear.

FIG. 2 shows an alternative embodiment of a frame 1. The front side frame 10 is designed according to Figure 1 as a flat profile. At the front of the side frame 10, the driving element 7 is in turn arranged. Above the driving element 7, a series of U-shaped receptacles 12 are arranged for skewer 4, advantageously regularly spaced from each other. The remaining area of the frame 1 is from stab resp. tubular elements 13 formed. In this case, the receptacles 12 of the side frame 10 opposite receptacles by appropriate Bends 12 'of the side frame 10 opposite rod member 14 formed. As rod elements 13, for example, thin iron resp. Steel bars resp. tube are used, which are bent into the appropriate shape and welded together.

FIG. 3 shows a further embodiment of the side frame 10 of the frame 1 according to the invention in a partial detail. The side frame 10 is formed as an upwardly open hollow profile. The receptacles 12 are each formed by opposing U-shaped slots in both side walls of the side frame 10. The driving element 7 can now be arranged in the interior of the hollow profile and is thus at least laterally protected against unintentional access. The skewer 4 is now inserted into the receptacle 12 so that the driving plate 6 comes to lie between the two side walls of the side frame 10 and there protected in engagement with the driving element 7 passes.

FIG. 4 shows the longitudinal section through a skewer 4 designed according to the invention. The skewer 4 consists of a provided at its right end with a tip rod 15 which is inserted on the left side in a centrally arranged in the handle 5 opening. The rod 15 may either be releasably clamped only by frictional engagement in the handle 5 or be frictionally connected, for example by means of a pin or screw with the handle 5. The rod 15 may be a round or advantageously a square Cross-section, which facilitates, among other things, the attachment and fixing of Grillgut.

At the tip of the rod 15 facing side of the handle 5, the driving plate 6 is arranged against rotation. For this purpose, the driving plate 6 may be bolted to the handle 5, for example.

In Figure 5, the front view is shown on the spit 4, in which case in particular the formation of the toothing 6 'on the circumference of the driving plate 6 is particularly well visible. These teeth 6 'can engage in correspondingly formed openings of the driving element 7, whereby the driving plate 6 rotates upon displacement of the driving element 7 about the axis of the rod 15 of the skewer 4. FIG. 6 shows the plan view of the deflection region of FIG

Driving element 7 shown. The driving element 7 is designed here in the form of a link chain and is guided by a gear 16 as a guide wheel 9 and driven. The gear 16 may, as shown in Figure 1, for example, be formed by a crank 8 manually rotatable. Alternatively, however, a motorized drive can also be used, for example an electric motor provided with a reduction gear (not shown for the sake of clarity) which is operatively connected to the gear 16 either directly or via a further belt or chain.

A major advantage of the device according to the invention is that one or preferably several skewers, regardless of the drive at any time simply by hanging up the frame 4 can be arranged on the grill pan 2, and thereby automatically operatively connected to the driving element 7 to be manually operated or automatically rotated about its axis. If the corresponding grill food is optimally grilled, the corresponding skewer can be lifted without interruption of the drive of the grill pan 2.
