Abstract

The invention concerns a stove-grill wherein the link between the body (2) and the bowl (3) is provided by several matching assemblies, angularly spaced about the camp stove vertical axis and consisting, on one of the elements, of projecting catches (13) and on the other element, slots (15) capable of being traversed by the catches (13) and provided with edges (14a) capable of co-operating with said catches such that, after the catches (13) have passed through their respective slots, the relative rotation of one element with respect to the other brings the catches (13) on an edge (14a) adjacent to the slot which it has traversed, while the support stand (10) consists of two pairs of identical legs (20) shorter in length than the bowl (3) inner dimension so as to be able to fit therein, and in each of said pairs, the upper connecting piece (18) of each of the legs (20) is shaped to be engaged in a cavity (17) of the body (2), equipped with locking means (22) which can be manually unlocked.

Description

SINGLE-BURNER GAS STOVE/GRILL The invention relates to a single-burner gas

stove/grill with a water bath for catching fat.

There is already known a stove/grill which comprises, connected securely and permanently together:

- a body comprising a burner, its means f or feeding it with burnable gas, and a control member, f or example a tap, - a stand, - and a water bath f or catching fat in the grill configuration.

The object of the present invention is to improve the ease of use of such a stove, and in particular the ease of cleaning it.

In accordance with the invention, as a main issue, means of removable connection are formed between the body and the bath.

This means that the bath can be detached easily from the rest of the stove and cleaned, for example in a conventional dishwasher.

As a preference, the connection between the body and the bath is provided by several complementary assemblies, spaced at angles around the vertical axis of the stove and composed, on one of the elements (body and bath) of protruding hooks and, on the other element, of cutouts through which the hooks can pass and which have edges that can interact with these hooks so that after the hooks have passed through their respective cutouts, a relative rotation of one element with respect to the other brings the hooks against an edge adjacent to the cutouts through which they have each passed.

As a pref erence, the stand is made up of two identical pairs of legs which have a length shorter than the interior dimension of the bath so that they can be stored therein, and, in each of the pairs, the upper end fitting of each of the legs is shaped to f it - 2 into a well in the body, which well is equipped with manually unlockable locking means.

It is clear from the foregoing that this stove/grill comprises legs and a removable bath which means that these can be cleaned very easily. As far as the legs are concerned, they can, once they have been removed, be placed in the bath to reduce the overall amount of space occupied by the stove and make it easier to store and to transport.

In one embodiment, the body is in the shape of a bowl with a central nipple projecting upward, and comprises, projecting from the horizontal bearing surface of this nipple, hooks facing radially outward, while the bath, which has a central chimney projecting upward from its bottom bearing on the nipple of the body, is secured to a ring attached against its bottom, the inner edge of said ring projecting radially into the chimney and comprising open-ended cutouts distributed in the same way as the hooks, and through which the latter can pass.

This device makes the operation of securing the bath to the body of the stove and detaching it therefrom very easy, and provides for a perfect connection between the two elements.

Advantageously, and in order to limit the relative rotation between the bath and the body, this bath comprises, in its bottom, a depression, the concave side of which faces downward and can fit over a projecting part of the body, this depression having edges whose spacing is determined to allow limited angular pivoting of the bath with respect to the body after the cutouts have been engaged over the hooks, this pivoting corresponding to the travel needed to lock the bath relative to the body.

other features and advantages will emerge from the description which follows with reference to the appended drawing which depicts, by way of example, one embodiment of this stove/grill; Figure 1 is an exploded perspective view showing the various components of the stove, Figure 2 is a perspective view showing, on an enlarged scale, the body of the stove and the bottom of 5 the bath, Figure 3 is a part view in section on III-III of Figure 2, showing, on an enlarged scale, the device f or locking one of the legs, Figure 4 is a plan view from above the bath, when it is placed over the body of the stove and not locked, Figure 5 is a part view in section on V-V of Figure 4 showing, on an enlarged scale, the means of connecting the bath to the body, Figure 6 is a view in part section of the stove when it is in the storage position.

As shown in Figure 1, this stove/grill is made up of a stove body 2 and of a bath 3, the upper edge of which can support a cross-shaped support 4 for a pan, or a grill 5. The body 2 comprises a burner 6, means of supplying burnable gas, and a tap or member for controlling the flow rate of burnable gas, the latter components not being depicted. The tap can be operated by a radial stem 7 fitted with a control knob. The gas- supply means, arranged in the lower part of the body 2, comprise means of coupling to a cartridge 9 (disposable container) or reservoir (refillable container) or alternatively any other source of pressurized burnable gas.

The body 2 is associated with a stand 10.

As shown in greater detail in Figure 2, the body 2 is in the shape of an annular bowl 2a from which there projects a central and circular nipple 2b with an upper bearing wall 2c. This wall has slots 12 passing through it, to allow air to the burner 6, and has upwardly projecting hooks 13. These hooks, of which there are three, are distributed at 1200 apart and face outward.

The bath 3 has a flat bottom 3a which can rest on the wall 2c of the body. As shown in Figure 6, this bottom is bordered, toward the outside, by an annular bowl 3b, the bearing ring 3c of which can come into contact with the peripheral edge of the bowl 2a of the body and, toward the inside, by a central chimney 3d which guides the secondary ventilation toward the burner, and allows the latter to pass. This chimney, projecting vertically upward from the bottom 3a of the bath, has an inside diameter which is larger than the diameter across which the hooks 13 are distributed, which hooks thus lie inside this chimney when the bath 3 is resting on the body 2. Fixed against the bottom 3a, for example by welding, is a ring 14 whose internal edge 14a, visible in Figure 2, projects into the chimney and has an inside diameter which allows it to pivot around the uprights 13a of the hooks 13, as shown in Figure 5. Likewise, the ring 14 has a thickness which allows it to fit with friction under the turned over parts 13b of the hooks. Passing through this ring are cutouts 15 which are open to the inside and have a width which slightly exceeds the width of the turned over parts 13b of the hooks 13. There are three of these cutouts 15, just as there are three hooks 13, and they are distributed at 1200 apart, so that they can f it over the hooks 13 when the bath 3 is placed on the body 2. To complete assembly between the bath and the body, all that is required is for the bath 3 to be turned relative to the body 2 so that the edge 14a adjoining the cutouts 15 passes under the hooks 13, providing a connection in terms of vertical translation between the bath 3 and the body 2.

Figure 4 shows that the annular bowl 3b formed in the bottom of the bath 3 has a depression 16. The latter, the concave side of which faces downward, is intended to fit over the protruding stem 7 of the tap.

When the bath 3 is f itted over the body 2, the spacing of the edges of the depression acts as a positive location means which makes it easier for the cutouts 15 to be made to coincide with the hooks 13 and which, as the bath 3 is rotated relative to the body 2, limits the locking travel by abutting, via one of its edges, against the stem 7.

Projecting upward from the bowl 2a of the body 2 are vertical wells 17 each capable of housing the upper end fitting 18 of each of the legs 20 which make up the stand 10, each end fitting being cylindrical with two opposed flats 19. Each well 17 therefore has a cross section that complements each end fitting 18.

As shown in greater detail in Figure 1, in each leg, the f lat 19 which faces outward has a groove 21 passing transversely across it. As the end fitting 18 of the leg is fitted into the corresponding well 17, this groove interacts with a catching tooth 22 formed on an elastic tab 23 forming one of the sides of the well and opposite the flat 19; cf. Figure 3.

In order to secure each pair of legs 20 to the body, all that is required is for the two end fittings 18 of each pair of legs to be fitted into the corresponding wells 17 until the catching teeth 22 clip into the grooves 21. To release the legs, each tab 23 needs to be moved away from the corresponding end fitting 18, this operation being assisted by the fact that the tab 23 is longer than the corresponding well 17.

Advantageously, in each pair, the legs 20 have a length which is shorter than the diametral dimension of the interior of the bath 3, which allows these legs to be placed in this bath, as shown in Figure 6, f or transporting the stove. This figure shows thatwhen they are in the bath 3, these legs do not impede the placing of the cross-shaped support 4 and of the grill 5.

When the bath is in the storage configuration, and as shown in Figure 6, the various components of the stove, other than the body 2 and the bath 3, are held together by a lid 24, the peripheral edge 24a of which fits with friction over the upper edge of the water - 6 bath 3, and at a height that allows it to fit over the grill 5 and the cross-shaped support 4.

When dismantled, this stove/grill forms a compact and self-contained assembly which can easily be stored and transported, for example in a bag or case, and comprises components which can be assembled and dismantled very easily, providing a perfect connection between these.
