Description

Pressure cooker with detachable handle {A PRESSURE COOKER APPLIANCE WITH REMOVABLE HANDLES}

Pressure cookers for home use are already known, including lids designed to be locked to said container in an airtight manner by means of a container and an elastic gasket.

Instruments used under pressure require safety precautions, particularly with regard to the locking of the container and lid. As a result, there are various types of pressure cookers with different locking / unlocking systems.

Also known is a bayonet type pressure cooker comprising a container and a lid each formed with a lamp set of a lamp and a lamp of the container overlapping in a closed position to be locked in a position after being overlaid by a locking system, for example. . In a known total desorption autoclave, a lock is secured by the container and lid handles that are overlapped in a locked position to actuate the respective locking system between the container handle and the lid handle.

In general, instruments of the above manner are satisfactory, but there are problems related to the inconvenience of operating the instrument, a large volume that is difficult to handle, and a large space required for storing the instrument. Since the handle of the pressure cooker in this manner is an essential element for locking the pressure cooker, the handle of the container and the lid is permanently fixed to the container and the lid and cannot be removed or removed. In addition, as a result of the locking function performed by the handles, it is necessary to provide a relatively large handle, which makes the storage and operation of the instrument inconvenient.

Also known is a pressure cooker called a "manhole autoclave" which provides a substantially egg-shaped container in which a complementary lid is inserted therein in an airtight manner. In that type of pressure cooker, the lid is likewise secured on the vessel by locking and interaction with the vessel handle on the lid handle. Although generally smaller in size, such pressure cookers also suffer from inconvenience in handling and storage.

In addition, since such instruments are often handled during operation under pressure, it has never been considered to remove all or part of the handle.

In the general field of cooking utensils, it is known that frying pans or other pans are adapted to have a handle detachable by quick detachable tools.

The disclosed subject matter relates to the general technical field of pressure cookers for home use, as an appliance designed to cook food under pressure.

The disclosed invention relates to a pressure cooker comprising a container and a lid locked over the container by locking / unlocking means detachable from the handle means of the cooking utensil. The invention also relates to a mechanism comprising the container and the lid together with a set of handles and also to such a handle.

The object endowed with the present invention ultimately seeks to improve on the various disadvantages mentioned above and is particularly easy to handle and operate with a locking / unlocking means for locking and detaching the lid over the container, independent of the handle means for the instrument. It is to propose a new pressure cooker that can be made more reliable.

Another object of the present invention is to propose a new pressure cooker which is convenient for storage and particularly safe in operation.

Another object of the present invention is to propose a pressure cooker which is particularly simple to complete.

Another object of the present invention is to propose a pressure cooker which is particularly simple in design and production and inexpensive.

It is a unique object of the present invention to propose a new pressure cooker comprising a particularly simple detachable handle system which is applied to a pressure cooker having a totally detachable closure.

The object imparted to the invention is achieved by the pressure cooker comprising a lid which is locked onto the container by means of a locking / unlocking means independent of the handle means for the appliance together with the container, wherein the handle means are each combined with a first combination. And means for forming a second coupling means and adapted to be removably mounted on the container via quick coupling means coupled to the container and the handle means, wherein the first coupling means is adapted when the lid is locked onto the container. The handle means designed to be mounted on the first coupling means are securely locked onto the container in such a way that it cannot be separated from the first coupling means.

1 to 6 show a pressure cooker according to the invention, which comprises a container 1 which is generally made cylindrical by a method such as stamping an aluminum or stainless steel type metal material. The bottom 2 below the container 1 is firmly integrated by a method such as a hot press. The container 1 is defined by an outer wall 3 which rises approximately vertically from the bottom and at the top ends with a container edge 6 folded outward from the instrument.

The pressure cooker described below is preferably a pressure cooker having a total detection detachment closing portion. However, since the locking / unlocking means for locking or detaching the lid to the container is independent of the handle means for the appliance, it can be easily understood that the present invention can be applied to any type of pressure cooker for home use. have.

In a totally detachable pressure cooker, the folded edge 6 of the container 1 is provided with a series of radially projecting vessel lamps 5 at predetermined intervals. In the example shown in FIG. 2, the container 1 is provided with four container lamps 5 which are located at an angle of 90 degrees to the opposite side of the diameter.

The pressure cooker according to the invention also comprises a lid 7 which is designed to be immersed above the container 1 in an airtight manner by means of a sealing gasket 8. The lid 7 is also provided with a lid lamp and a lamp spacer 9. At the end of the lid lamp, the container 1 is provided with respective folded inwardly curved edges 9A which are formed to engage with each other by their shape in the container lamp 5 so that the lid is locked or unlocked. In such a case, the vessel lamp 5 and the lid lamp 9A have been filed by the applicant or by rotation locking means for securing the position of the lid 7 mutually to the vessel 1 but have not yet been disclosed. And other rotary locking means described in French patent applications FR-98 12258 and FR-98 12259. The assembly of the vessel lamp 5 with the rotary locking means and the lid lamp 9A forms a locking / releasing means of the pressure cooker.

The pressure cooker according to the invention is also provided with handle means 10, 11, for example handles formed by short handles and long handles, respectively.

In a first aspect of the invention, the handle means (10, 11) is attached to the container (1) to be detachable by a quick coupling means, each of the first coupling means constituting the quick coupling means is the container (1) ) Is integrated into the handle means. In this first feature, it is necessary to make the locking / releasing means for securing the rotational locking of the lid 7 above the container 1 independent of the handle means 10, 11 for the instrument.

In the present invention, the handle means 10, 11 are thus formed with one or more removable handles suitable for being quickly mounted and removed from the container by the user while being securely locked in position on the container when engaged. Preferably, such removable handles are made to conform to the principles described in patent EP-0 769 263 or patent EP-0 906 742 by the applicant. Accordingly, the handles 10 and 11 are relatively translatable in the longitudinal direction in the handle proper 23 of the handle, so that the handle 21 and the other member 23 fixed relative to the handle proper 23 are fixed. Two clamped members 21, 22. The members 21, 22 are thus formed by quick coupling means integrated into the handle means 10, 11, which will be referred to later as second coupling means.

In the present invention, when the lid 7 is locked or in the locked position on the container 1, the detachable handle means 10, 11 are formed to be mounted on the first coupling means. ) Is firmly fixed to the container 1 by means of first coupling means fastened or fastened to the container 1 in such a way that it cannot be removed from the first coupling means.

Such mounting ensures that the handle means 10, 11 can not be separated even by chance when the lid is in the locked position on the container, making it particularly safe to operate and handle the pressure cooker according to the invention.

As clearly shown in FIGS. 3 to 6, the first coupling means is welded on the wall 3 in the case of the vessel being made of stainless steel, or the vessel 1 being made of aluminum, or the like. In this case it can be formed as a yoke (30) shaped yoke that can be riveted. In a preferred manner, the yoke 30 made of a metallic material may be provided with a mounting collar 31, such as a semicircle, defining a housing 32 that is open toward the top of the instrument, the housing 32 being A semi-circular side face 33 extending the mounting collar 31, a front face 34 extending the side face 33 while bending upwards outward, and an outer side of the wall 3 of the container 1. The range is determined by the plane.

Naturally, the relative shape of the surface components of the yoke 30 and the surface components of the members 21, 22, including the coupling means of the handle means 10, 11, are paired, providing accurate clamping. Combined in a way. In this mounting, the movable member 21 allows the front face 34 to be clamped between the movable member 21 and the fixing member 22 so that the grip means 10, 11 are fixed perpendicular to the side in the fixed position. It is inserted perpendicularly to a stable retention position in the housing 32 to ensure that it is secure.

The position of the yoke 30 forming the first connecting means makes the handle means 10, 11 inseparable, ie the handle means 10, 11 when the lid 7 is locked onto the container 1. It is selected to be non-removable from the housing 32. Preferably, such function is provided by the lid 7 itself when in the locked position of the lid corresponding to the engagement of the container lamp 5 with the lid lamp 9A. Naturally, such an arrangement is particularly convenient because it does not require any change of instrument shape.

Thus, with such a mounting, the lid 7 is provided with the first and second coupling means mutually connected when the handle means 10, 11 are mounted to the container 1 and the lid 7 is locked to the container 1. In order to prevent them from being coupled to each other, it comprises a vertical fixing means in accordance with the handle means (10, 11), or forms the form of such fixing means.

As shown in FIGS. 3-6, in a preferred use of yoke 30, the first coupling means 30 is at a distance d (shown in FIG. 4) from the upper edge 6 of the container 1. It is fixed to the wall 3 of the container 1. Thus the distance of d here determines the distance for removal of the handle means 10, 11 from the yoke 3. Such a spacing approximately coincident with the height of the moving member 21 first allows the member to be positioned vertically with respect to the housing 32 and engaged therein. Accordingly, it will be appreciated that the mutual position of the yoke 30 and the lid 7 when in the closed or locked position is to reduce the distance of d which prevents the removal of the handle that the lid 7 is located in the housing 32. .

Thus, in the case of a cookware formed by a pressure cooker comprising a total detection detachment closing system having a container lamp 5 and a lid lamp 9A, the locking means is provided with a lid lamp spacer (which reduces the distance d ). 9) and the gap for removing the grip means 11 from the yoke 30. In such a configuration, the yoke 30 and the handles 10, 11 are not mounted correspondingly to the vessel lamp 5. In other words, they are mounted in angular portions that are not vertically fitted to the vessel lamp 5.

In the example shown in FIG. 5, the lid 7 is in the unlocked position in which the lamp spacer 9 is not vertically aligned with the grip means 11 and the yoke 30. In this position, the grip means 11 are freely inserted into or detached from the housing 32 at the portion corresponding to the lid lamp 9A which extends between the lid lamp spacers 9 and is shorter in height than the lid lamp spacers 9. Can be. On the other hand, during the closing and locking, the lid lamp spacer 9 is brought into contact with the yoke 3, thereby reducing the distance of d and preventing the handle means 11 from being separated from the yoke 3.

For example, as shown in Figure 6 with the modified method, made to form a locking means as a separate part that is fixed to the lid, or even vertically to match the yoke 30 and the holding means (10,11), d It is possible to extend the lid 7, for example in the lamp 9A, in a manner to limit the distance of the. In the example shown in FIG. 6, the locking means is formed as part 40 extending the edge of the lid 7 approximately vertically. In another variant (not shown), the fastening means 40 is in the lamp 9A or lamp spacer 9 depending on the position of the yoke 30 relative to the welded plate or even the rod or vessel lamp 5. It may be formed by any equivalent means that fits the lid 7.

In a special variant as shown in FIG. 7, the height d when the handles 10, 11 are fixed in line with the vessel lamp 5 by making a vertical center projection 9B on and extending from the lid lamp 9. Can be reduced, thus avoiding the addition of additional parts. Such appliances have separable handles to facilitate storage due to the space saved, but the handles cannot be removed when the cookware is locked so that the pressure cooker can be obtained in a simple manner without affecting the overall safety of the appliance. do.

Such pressure cooker mechanisms can be sold with several types of detachable handles optionally formed by pairing short and long handles in sets so that the user can use the functions as desired at the moment he or she needs.

The industrial field of use of the present invention is in manufacturing pressure cooker appliances for home use.
