Description

Detailed Description of the Invention

TECHNICAL FIELD The present invention relates to the general technical field of household pressure cookers manufactured for cooking food under pressure.

The present invention provides a ball and handle means (of the handle or knob type) for instruments.
A lid which is locked on the ball by locking / unlocking means independent of. The present invention also relates to an instrument that includes a ball and lid with a set of handles, and to such handles. PRIOR ART It is already known to manufacture domestic pressure cookers, such as pressure cookers including a bowl and a lid, which are made to lock onto the bowl in a gastight manner using a resilient gasket. Is.

Devices designed to operate under pressure, especially those that lock with a lid on the ball, require special consideration to ensure safety. As a result, there are various types of pressure cookers that differ primarily in locking / unlocking devices.

Thus, for example, a bayonet comprising a respective set of balls and lid lamps designed to be stacked in a closed position for the purpose of being locked in that position by a locking device, each having such a ball and lid. Type pressure cookers are known. In the popular bayonet type pressure cooker, since the respective lock devices are operated between the ball handle and the lid handle, the lock is reliably performed by using the ball and the lid handle so that they are stacked in the locked position. Be seen.

In general, a device of that type is satisfactory provided there are no obstacles to the handling of the device, such as the number of rooms required to store the device. The handle of that type of pressure cooker is an essential element for locking the pressure cooker, and the ball and lid handle is permanently mounted on the ball and lid and cannot be removed or tidyed 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 the instrument difficult to store, while also making them difficult to handle. Become.

Pressure cookers, referred to as “manhole pressure cookers”, are known as substantially oval-shaped cookware in which complementary shaped lids are inserted in an airtight manner. In that type of pressure cooker, the lid is similarly locked to the bowl in cooperation with the locking of the bowl handle on the lid handle. Although smaller in size than usual, such pressure cookers also present obstacles with respect to handling and storing them.

In addition, the removal of all or some of the handles has heretofore not been recognized, since such devices are often handled under pressure.

[0008] In the general field of home cookware, frying pans and other breads are known, which are suitably equipped with a handle that is removable using a quick coupling / disengaging device. SUMMARY OF THE INVENTION As a result, the object given to the present invention is to seek a remedy for the various disadvantages mentioned above, from a handle means for an instrument for locking the lid on the ball and removing it from the ball. The object is to propose a new pressure cooker with independent locking / unlocking means, which is easy to handle, in particular reliable in use and more compact. That is.

Another object of the present invention is to provide a novel pressure cooker which is particularly safe to operate and easy to store.

Another object of the present invention is to provide a novel pressure cooker which is particularly simplified.

Another object of the invention is to provide a novel pressure cooker, which is particularly simple and inexpensive to design and manufacture.

A new object of the invention is to provide a new pressure cooker including a device of a removable handle for particularly easy attachment to a pressure cooker with a bayonet pin.

The object given to the invention comprises a ball and a lid which is locked on the ball by a locking / unlocking means independent of the handle means for the instrument, the handle means comprising the ball and the handle means. Suitable for releasable attachment to the ball by means of a quick coupling means fixed to the first and second coupling means respectively, said first coupling means being adapted for locking the lid to the ball. , A pressure cooker method that is permanently attached to the bowl so that the handle means made to be mounted thereon cannot be removed from the first coupling means. 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. Figure 1
Figures 6 to 6 show a pressure cooker according to the invention. The pressure cooker comprises a generally cylindrical bowl 1 made by stamping a metallic material such as aluminum or stainless steel. The ball 1 comprises a bottom 2 formed under it, for example by hot pressing. The ball 1 is formed by an outer wall 3 which rises substantially vertically from the bottom and terminates at the apex in a ball edge 6 folded outward of the device.

The pressure cooker described in the following description is preferably a pressure cooker having a bayonet type closure. The present invention is applicable to any type of pressure cooker used at home, as the locking / unlocking means for locking and removing the lid on the bowl is independent of the handle means of the appliance. it can.

In the bayonet type pressure cooker, the folded edges 6 of the bowl 1 are formed at any regular spacing corresponding to a series of radially projecting ball ramps 5. In the embodiment shown in FIG. 2, the ball 1 has four ball ramps 5, which are diametrically opposed and are spaced apart by an angle of 90 degrees.

The pressure cooker of the present invention is also hermetically sealed using the sealing gasket 8 to make the ball 1
It includes a lid 7 designed for mounting on top. The lid 7 also includes a lid lamp and a lamp spacer 9. The lid ramp has a recessed edge 9 designed to cooperate with the shape of the ball ramp 5 that locks and unlocks the lid on the ball 1.
It is provided at the end of A. In that case, the ball lamp 5 and the lid lamp 9A may be rotation lock means for locking the position of the lid 7 in relation to the ball 1, or, for example, French by the same applicant, which has not been published when the present application was filed. National application F
It is associated with other forms of rotation locking means described in R98 11258 and FR98 12259. The assembly of the ball lamp 5 and the lid lamp 9A forms the locking / unlocking means of the pressure cooker with the rotation locking means.

The pressure cooker of the present invention comprises handle means 10, 11 forming, for example, a short handle and a long handle, respectively.

In the first aspect of the invention, the handle means 10, 11 are suitable for being removably attached to the ball 1 by means of a quick coupling means. It is respectively fixed to the ball 1 to form the first connecting means and to the handle means 10, 11 respectively to form the second connecting means which is fixed to the handle means. In this first aspect it is necessary for the locking / unlocking means to ensure a rotary lock of the lid 7 on the ball 1 which is independent of the handle means 10, 11 for the instrument.

In the present invention, thus, the handle means 10, 11 are securely locked in position on the ball when they are connected and are fast and surely mounted on the ball, depending on the user. Form one or more removable handles to be removed therefrom. Such a detachable handle is disclosed in Patent EP-0769.
263 or commonly-assigned patent application EP-0906742, made in accordance with the principles set forth therein. As such, 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. The other member 22 is fixed with respect to the handle proper 23. Thus, the members 21, 22 form a quick connecting means which is fixed to the handle means 10, 11 shown below as the second connecting means. In the present invention, when the lid 7 is locked in the locked position on the ball 1, the detachable handle means 10, 11 are fixed to the ball 1 first.
It is designed to be permanently fixed to the ball 1 using coupling means. The handle means 10, 11 are designed so that they cannot be removed from said first means and mounted on them.

Such a mounting does not allow the handle means 10, 11 to be reliably removed by accident if the lid is in the locked position on the ball, so the pressure cooker of the present invention is particularly easy to handle. And the operation becomes safe.

As clearly shown in FIGS. 3 to 6, the first coupling means can be formed, for example, by a welded yoke 30 when the ball 1 attached to the wall 3 is made of stainless steel. When the ball 1 is made of aluminum, it can be attached with rivets, for example. In a preferred manner only, the yoke 30 made of metallic material can be formed by a mounting collar 31, for example defined by a semi-circular dressing opening towards the top of the device. The housing 32 is bounded by a semi-circular side surface 33 which reaches the mounting collar 31, a front surface 34 which curves outwards towards the top and reaches the side surface 33, and by the outer surface of the wall 3 of the ball 1.

Originally, the shape of the surface member of the yoke 30 and the shape of the members 21, 22 constituting the connecting means for the handle means 10, 11 are each adapted and combined for optimal clamping. 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. This causes the handle means 10, 11 to be joined vertically and laterally in the fixed position.

The position of the yoke 30 forming the first coupling means is chosen such that the handle means 10, 11 are stationary. That is, when the lid 7 is locked on the ball 1,
The handle means 10, 11 cannot be removed from the housing 32. 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 with the lid lamp 9A. Of course,
Such a device is particularly simple since it does not require any modification in the design of the instrument.

Thus, in such an installation, the lid 7 comprises locking means having handle means 10, 11 which are set vertically when mounted on the ball 1 or when the lid 7 is locked on said ball 1. And a locking means for preventing the respective first and second coupling means from being disengaged.

As shown in FIGS. 3 to 6, in a preferred use of the yoke 30, the first coupling means 3
0 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 represents 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 it to be initially aligned vertically with the housing 32 and engaged therein. Thus, the relative position of the yoke 30 and the lid 7 in the closed or locked position requires the lid 7 to require a distance d, thus preventing movement of the handle in position within the housing 32. There must be.

Thus, in the case of a cookware formed by a pressure cooker including a bayonet type sealing device having a ball lamp 5 and a lid lamp 9A, the locking means may be a distance d (FIG. 5) and the yoke 30 to the handle means 11 It is formed by the lid lamp spacer 9 in which the clearance for removing 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 mounted vertically on the ball ramp 5 but mounted in the normal area.

In the example shown in FIG. 5, the lid 7 is in the unlocked position and the lamp spacer 9, which is positioned not vertically, is set on the handle means 11 and the yoke 30. In this position, the handle means 11 can be freely plugged in or removed from the housing 32 in the area extending between the lid lamp spacers 9, smaller in height than the lid lamp spacers 9 and corresponding to the lid lamps 9A. be able to. In contrast, when closed and locked, the lid lamp spacer 9 is set on the face of the yoke 30, which reduces the distance d and makes it impossible to remove the handle means 11 from the yoke 30.

As a variant, as shown for example in FIG. 6, it is possible to make the locking means in the form of separate parts which are fixed to the lid and reach the lid. That is, the lamp 9A
The yoke 30 and the handle means 10 and 11 are set vertically so as to limit the distance d by. In the example shown in FIG. 6, the locking means is formed by a portion 40 that extends substantially vertically to the edge of the lid 7. In another variant (not shown), the locking means 40 can be formed by means of welded plates, also by rods and also by equivalent means, which can be attached to the lid 7 by means of lamps 9A or lamp spacers 9. It can be made dependent on the position of the yoke 30 with respect to the ball ramp 5.

In the particular variant shown in FIG. 7, the addition of additional parts is avoided and the handle 10
, 11 are set on the ball lamp 5 by making them vertical, and the height d can be reduced when mounted in the central protrusion 9b extending from the lid lamp 9. Such a device makes it possible, in a simple way, to obtain said pressure cooker with a removable handle, 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.

Subsequent pressure cookers with a variety of removable handles in a set of short or long handles to fit such options will be sold. The user can use it according to his / her needs at that time. Occurrence of Industrial Applications Industrial applications of the present invention exist in the manufacture of pressure cookers for home use.
