Description

[0001]
[Technical field]
The present invention relates to the general technical field of household pressure cookers manufactured for cooking food under pressure.
[0002]
The present invention includes a ball and a lid that is locked onto the ball by means of locking / unlocking that is independent of the handle means (handle or knob type) for the instrument. The present invention also relates to an instrument comprising a ball and lid with a set of handles and to such a handle.
[Conventional technology]
The manufacture of household pressure cookers, such as pressure cookers including balls and lids, that are made to lock onto the balls in an airtight manner using a resilient gasket is already known.
[0003]
Devices designed to operate under pressure, particularly those that lock with a lid on the ball, require special considerations to ensure safety. As a result, there are various types of pressure cookers that differ primarily in lock / unlock devices.
[0004]
Thus, for example, a bayonet type pressure cooker that includes a respective set of balls and lid lamps designed to be stacked in a closed position for the purpose of being locked in place by a locking device, each having such a ball and lid Instruments are known. In a popular bayonet type pressure cooker, each locking device is operated between the ball handle and the lid handle, so that the lock is securely performed by using the ball and the lid handle so that they are stacked in the locked position. Is called.
[0005]
In general, an appliance of that type is satisfactory if there are no obstacles to handling the appliance, the number of rooms required to store the appliance, and the like. The handle of that type of pressure cooker is an essential element for locking the pressure cooker, and the ball and lid handle are permanently mounted on the ball and lid and cannot be removed or tidied up. In addition, as a result of the locking function performed by the handle, it is necessary to provide a relatively large handle, which makes it difficult to store the instrument, while also making them difficult to handle Become.
[0006]
A pressure cooker, referred to as a “manhole pressure cooker”, is known as a substantially egg-shaped utensil in which a complementary shaped lid is inserted in a manner that seals inwardly. In that type of pressure cooker, the lid is similarly locked to the ball in cooperation with the ball handle lock on the lid handle. Although usually smaller in size, such pressure cookers also have obstacles related to the difficulty of handling and storing them.
[0007]
In addition, since such instruments are often handled under pressure, it has not been previously recognized to remove all or some of the handles.
[0008]
In the general field of home cooking utensils, frying pans and other pans are known, and they are suitably equipped with a handle that is detachable using a quick coupling / release device.

[Best Mode for Carrying Out the Invention]
The best mode of the present invention will be described in more detail with reference to the accompanying drawings. 1 to 6 show a pressure cooker according to the present invention. This pressure cooker includes a generally cylindrical ball 1 made, for example, by stamping a metal material such as aluminum or stainless steel. The ball 1 has a bottom 2 formed underneath, for example, by a hot press. The ball 1 is formed by an outer wall 3 that rises substantially vertically from the bottom and ends at the apex in a ball edge 6 that is folded out of the instrument.
[0014]
The pressure cooker described in the following description is preferably a pressure cooker having a bayonet type sealing device. The present invention is applicable to any type of pressure cooker used in the home because the locking / unlocking means for locking and removing the lid on the ball is independent of the handle means of the appliance. it can.
[0015]
In a bayonet type pressure cooker, the folded edges 6 of the ball 1 are formed at any regular interval corresponding to a series of radially projecting ball lamps 5. In the embodiment shown in FIG. 2, the ball 1 has four ball ramps 5 which are opposed along the diameter and are spaced apart by an angle of 90 degrees.
[0016]
The pressure cooker of the present invention also includes a lid 7 that is designed to be hermetically sealed using a sealing gasket 8 and mounted on the ball 1. The lid 7 also includes a lid lamp and a lamp spacer 9. The lid lamp is provided at the end of the indentation edge 9A designed to cooperate with the shape of the ball lamp 5 that locks and unlocks the lid on the ball 1. In that case, the ball lamp 5 and the lid lamp 9A may be rotational locking means for locking the position of the lid 7 relative to the ball 1 or, for example, French by the same unpublished applicant at the time this application was filed. In connection with other forms of rotational locking means described in national applications FR98 11258 and FR98 12259. The assembly of the ball lamp 5 and the lid lamp 9A forms a lock / unlock means for a pressure cooker having a rotation lock means.
[0017]
The pressure cooker according to the invention comprises, for example, handle means 10, 11 forming a short handle and a long handle, respectively.
[0018]
In the first aspect of the present invention, the handle means 10, 11 are suitable for being detachably attached to the ball 1 by a quick coupling means. It is fixed to the ball 1 respectively to form the first coupling means and fixed to the handle means 10, 11 to form the second coupling means fixed to the handle means. In this first feature, it is necessary for the locking / unlocking means to ensure the rotary lock of the lid 7 on the ball 1 independent of the handle means 10, 11 for the instrument.
[0019]
In the present invention, the handle means 10, 11 are thus securely locked in position on the ball when they are connected, and are reliably and quickly mounted on the ball and removed from it by the user. Forming one or more removable handles. Such a detachable handle is conveniently made according to the principles described in patent EP-0769263 or commonly assigned patent application EP-0906742. Thus, the handles 10, 11 include two clamp forming members 21, 22. The member 21 is movable longitudinally with respect to the handle proper 23 of the handle. Another member 22 is fixed with respect to the handle proper 23. Thus, the members 21 and 22 form a quick coupling means fixed to the handle means 10 and 11 shown below as the second coupling means. In the present invention, when the lid 7 is locked at the locked position on the ball 1, the detachable handle means 10, 11 are permanently attached to the ball 1 using the first coupling means firmly fixed to the ball 1. Designed to be fixed. The handle means 10, 11 are designed so that they cannot be removed from the first means and mounted thereon.
[0020]
In such attachment, since the handle means 10 and 11 cannot be reliably removed even if accidentally if the lid is in the locked position on the ball, the pressure cooker of the present invention is particularly easy to handle and operate. Become safe.
[0021]
As clearly shown in FIGS. 3 to 6, the first coupling means can be formed by, for example, a welded yoke 30 when the ball 1 attached to the wall 3 is made of stainless steel. When is made of aluminum, it can be attached, for example, with rivets. In a preferred manner only, the yoke 30 made of a metallic material can be formed by a mounting collar 31 defined, for example, by a semicircular covering that opens towards the top of the instrument. The housing 32 is delimited by a semicircular side surface 33 that reaches the mounting collar 31, by a front surface 34 that curves outwards and reaches the side surface 33 and by the outer surface of the wall 3 of the ball 1.
[0022]
Originally, the shape of the surface member of the yoke 30 and the shape of the members 21 and 22 constituting the coupling means for the handle means 10 and 11 are adapted and coupled so that an optimum clamping is performed. In this attachment, the movable member 21 can be inserted upright into the housing 32 at a stable stop position of the front surface 34 fixed between the movable member 21 and the fixed member 22. Thereby, the handle means 10, 11 are coupled vertically and laterally in a fixed position.
[0023]
The position of the yoke 30 forming the first coupling means is selected so that the handle means 10, 11 do not move. That is, the handle means 10 and 11 cannot be removed from the housing 32 when the lid 7 is locked onto the ball 1. Such a function is provided by the lid 7 itself when the lid 7 is in the locked position corresponding to the engagement of the ball lamp 5 having the lid lamp 9A. Of course, such a device is particularly simple since it does not require any improvement in the design of the instrument.
[0024]
Thus, in such attachment, the lid 7 includes locking means having handle means 10, 11 set vertically when attached to the ball 1 or first when the lid 7 is locked to the ball 1. And a locking means for preventing the second coupling means from being removed from each other.
[0025]
As shown in FIGS. 3 to 6, in a preferred use of the yoke 30, the first coupling means 30 is attached to the wall 3 of the ball 1 at a distance d (FIG. 4) from the top edge 6 of the ball 1. The distance d thus indicates the clearance for removing the handle means 10, 11 from the yoke 30. This clearance substantially corresponds to the height of the movable member 21 and allows the member to be first vertically aligned with and engaged with the housing 32. Thus, the relative position of the yoke 30 and the lid 7 at the end or locked position requires that the lid 7 requires a distance d, and therefore hinders the movement of the handle at a position within the housing 32. There must be.
[0026]
Thus, in the case of a cooking utensil formed by a pressure utensil including a bayonet type sealing device having a ball lamp 5 and a lid lamp 9A, the locking means is for removing the handle means 11 from the distance d (FIG. 5) and the yoke 30. Is formed by the lid lamp spacer 9 in which the clearance is reduced. In such a configuration, the yoke 30 and the handles 10 and 11 are attached to the ball lamp 5 without being aligned. That is, they are not set perpendicular to the ball lamp 5 but are attached to a normal area.
[0027]
In the example shown in FIG. 5, the lid 7 is in the unlocked position, and the lamp spacer 9 positioned not vertically is set to the handle means 11 and the yoke 30. In this position, the handle means 11 can be freely inserted or removed from the housing 32 in an area corresponding to the lid lamp 9A, which extends between the lid lamp spacers 9 and is smaller in height than the lid lamp spacer 9. be able to. In contrast, when closed and locked, the lid lamp spacer 9 is set on the surface of the yoke 30, thereby reducing the distance d and making it impossible to remove the handle means 11 from the yoke 30.
[0028]
For example, as shown in FIG. 6, as a modification, it is possible to make the locking means in the form of separate parts fixed to the lid and reaching the lid. That is, the yoke 30 and the handle means 10 and 11 are set vertically so as to limit the distance d by the lamp 9A. In the example shown in FIG. 6, the locking means is formed by a portion 40 that reaches the edge of the lid 7 substantially vertically. In another variant (not shown), the locking means 40 can be formed by a welded plate, also by a rod, by the same equivalent means and can be attached to the lid 7 with a lamp 9A or a lamp spacer 9. And can depend on the position of the yoke 30 with respect to the ball lamp 5.
[0029]
In the specific variant shown in FIG. 7, when additional parts are avoided and the handles 10, 11 are set to the ball lamp 5 by being vertical and are mounted in the central projection 9 b extending from the lid lamp 9 The height d can be reduced. Such a device can, in a simple manner, obtain said pressure cooker with a handle that can be removed, thereby facilitating its storage in the room and when the cooker is locked Since the handle cannot be removed, a truly safe instrument can be obtained without obstruction.
[0030]
Subsequent pressure cookers will be sold with a variety of detachable handles in a set of short or long handles that fit with such options. The user can use it according to the user's own needs at that time.
