Description

Technical Field

[0001] The utility model relates to a cooker. More specifically, the utility model relates to a cooker with a rotatable handle, wherein the handle can be vertically rotated between a first working position and a second retracted position, and the cooker has a locking assembly, wherein the locking assembly is configured to rigidly lock the handle in a first locking position among the first working position and / or the second retracted position, and is also configured to allow the handle to rotate between the first working position and the second retracted position when the locking assembly is in a second unlocking position. Background Art

[0002] Typically, cookware (e.g., woks, frying pans, stockpots) are provided with handles that protrude from one side of the cookware body in a fixed manner. This makes it difficult to nest the cookware together and to store the cookware in a cupboard.

[0003] It is known in the art to provide a cooker with a rotatable or foldable handle, which can be rotated or folded to be placed along the circumference or periphery of the cooker, thereby reducing the physical space occupied by the cooker during storage. It is known that US Pat. No. 4,724,576 also provides a cooker with a rotatable handle, which can be rotated to be placed on the pot lid at an acute angle relative to the plane of the pot bottom for easy storage.

[0004] These handles generally include a locking assembly that allows the handle to be rotated and locked in either the operating position or the stowed position. However, it is often observed that the handle is not rigidly locked in each position, making the handle appear loose. This may be considered by some users as "poor quality". The looseness of the handle observed in the prior art is generally due to a loose fit of the components of the locking assembly, which is due to dimensional variations caused by manufacturing tolerances of the components.

[0005] Therefore, one object of the present invention is to provide a cooker with a rotatable handle provided with a locking assembly having a more rigid locking fit when the locking assembly is in the operating position and / or the stowed position.

[0006] Another object of the present invention is to provide a cookware set that can be easily nested together and has a reduced storage profile.

[0007] It is also an object of embodiments of the present invention to overcome at least one problem of the prior art, whether or not explicitly disclosed herein. Utility Model Content

[0008] According to a first aspect of the utility model, there is provided a cooker, comprising a body, the body having an outer wall, a bottom and a handle, the handle being vertically rotatable between a first working position and a second stowed position; in the first working position, the handle is oriented to extend away from the outer wall, and in the second stowed position, a major portion of the length of the handle is positioned to extend substantially parallel to the bottom or to lie horizontally on the body at a downward angle relative to the plane of the bottom; the handle has a proximal end and a distal end, the proximal end being rotatably fixed to the cooker via a connecting portion attached to one side of the cooker; wherein the handle includes a cavity therein, the cavity having a locking assembly, the distal end having a gripping member disposed thereon, the locking assembly including a locking member, the locking member being configured to move between a first locked position and a second unlocked position; wherein the proximal end of the locking member includes an upper surface at an acute angle relative to the plane of the handle, and the connecting portion includes a recess having an upper surface at an acute angle relative to the plane of the handle; wherein in the first locked position, the angled upper surface of the proximal end of the locking member engages a first contact point on the inclined upper surface of the connecting portion.

[0009] Advantageously, the locking assembly according to the first aspect of the utility model can enable the handle to be more rigidly fixed in the working position and / or the stowed position. Surprisingly, the inventors have observed that the locking assembly of the utility model still provides a rigid locking mechanism even when a manufacturing method with relatively high manufacturing tolerances is introduced in the various components of the cooker. Advantageously, this allows the use of a simpler and more cost-effective manufacturing process while still providing a handle with a rigid locked feel in the working and stowed positions. This may be considered by some users as a more expensive, higher quality product.

[0010] Furthermore, advantageously, the cookware of the present invention can be nested with a second, larger, similar cookware when the handle is in the stowed position because the handle is positioned substantially parallel to the bottom of the cookware or angled downward relative to the plane of the bottom. With the handle substantially parallel to the bottom or angled downward relative to the plane of the bottom, the handle does not contact the handle of the second, larger, similar cookware during nesting. Furthermore, by having the handle substantially parallel to the bottom or angled downward relative to the plane of the bottom in the stowed position, the overall footprint of the cookware is reduced, which improves storage convenience.

[0011] Preferably, the angled upper surface of the proximal end of the locking member rigidly engages a first contact point on the angled upper surface of the connecting portion.

[0012] Preferably, the recess of the connecting portion is located at the underside of the connecting portion.

[0013] The inclined / angled upper surface of the recessed portion may have an angle of 5-25°, 6-24°, 7-23°, 8-23°, 9-22°, 10-20°, 11-19°, 12-18°, 13-18°, 14-18° or 15-17° relative to the plane of the handle.

[0014] Preferably, the inclined surface of the recessed portion may have an angle of 15-17° relative to the plane of the handle.

[0015] The upper surface of the proximal end of the locking member may have an angle of 5-25°, 6-24°, 7-23°, 8-23°, 9-22°, 10-20°, 11-19°, 12-18°, 13-18°, 14-18° or 15-17° relative to the plane of the handle.

[0016] Preferably, the angled upper surface of the proximal end of the locking member has an angle of 12-18°, 13-18°, 14-18° or 15-17° relative to the plane of the handle.

[0017] Preferably, the angle of the angled upper surface of the recessed portion is the same or similar to the angle of the angled upper surface of the proximal end of the locking member.

[0018] Advantageously, when the angle of the angled upper surface of the recessed portion is the same or similar to the angle of the angled upper surface of the proximal end of the connecting portion, the proximal end of the locking member can enter the recessed portion of the connecting portion until it engages the first contact point. At this point, the locking member will not be retracted by rotational, vertical or lateral movement of the handle. This provides a rigid "feel" to the handle, thereby improving the perceived quality of the cookware. In addition, when the angle of the angled upper surface of the recessed portion is the same or similar to the angle of the angled upper surface of the proximal end of the locking member, this ensures that the proximal end of the locking member always rigidly engages the first contact point even when the size and / or shape of the proximal end of the locking member and / or the recessed portion of the connecting portion changes.

[0019] The proximal end of the locking member is configured to move into the recess along a path parallel to the length of the handle.

[0020] In some embodiments, in the locked position, the locking member can engage a second contact point on the cavity surface.

[0021] Preferably, in the locked position, the locking member rigidly engages the second contact point on the cavity surface.

[0022] The second contact point may be located on a lower surface of the cavity.

[0023] In one embodiment, the second contact point is located on the proximal lower surface of the cavity.

[0024] In such embodiments, a lower surface of the proximal end of the locking member is configured to engage the second contact point.

[0025] Advantageously, the engagement of the locking member with the second contact point minimizes the bending forces applied to the proximal end of the locking member when in the locked position. This helps to reduce damage to the locking member and also contributes to the rigidity of the locking assembly.

[0026] In another embodiment, the locking member may engage a second contact point on the cavity surface and a third contact point on the cavity surface.

[0027] Preferably, the locking member rigidly engages the second contact point on the cavity surface and the third contact point on the cavity surface.

[0028] In one embodiment, the third contact point is located on the upper surface distal to the cavity.

[0029] In such embodiments, the locking member includes a protrusion on a distal upper surface thereof that is configured to engage the third contact point.

[0030] Advantageously, the positive engagement of the third contact point provides further rigidity to the handle and ensures that the handle is positively locked in the operative and / or stowed position even if dimensions of components of the locking assembly and / or the cookware vary due to manufacturing tolerances.

[0031] In another embodiment of the present invention, in the first locking position, the locking member engages a first contact point on the upper surface of the recessed portion on the lower side of the connecting portion, a second contact point on the proximal lower surface of the cavity, and a third contact point on the distal upper surface of the cavity.

[0032] Preferably, in the first locked position, the locking member rigidly engages a first contact point on the upper surface of the concave portion of the underside of the connecting portion, a second contact point on the proximal lower surface of the cavity, and a third contact point on the distal upper surface of the cavity.

[0033] The locking member may include a trigger located on a distal lower surface thereof. The trigger may be configured to move the locking member from a first locked position to a second unlocked position.

[0034] The locking assembly may further comprise resilient biasing means configured to bias the locking member in the first locking position.

[0035] Preferably, the resilient biasing means is located at the distal end of the cavity.

[0036] Preferably, the resilient biasing means is a coil spring.

[0037] The proximal end of the handle may be rotatably fixed to the connecting portion by a rotatable fixing device.

[0038] The rotatable fixing means may comprise a bolt or a screw.

[0039] Preferably, the proximal end of the handle is fixed to the connecting part by means of a bolt.

[0040] The connecting portion may be attached to an outer wall of the cooker body.

[0083] In the description of the present application, it should be understood that the terms "top", "bottom", "inside", "outside", "up", "down", "front", "back", etc. indicating the directional position or position relationship are based on the directional position or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific directional position, be constructed and operated in a specific directional position, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0084] Figure 1 The cooker 1 shown in the figure has a generally cylindrical body 2 having a flat bottom 3 and a handle 4. The handle 4 is in a working position and the entire length of the handle extends away from the outer wall 5 of the body 2 at an upward angle relative to the plane of the bottom 3. The outer wall 5 of the body 2 and the bottom 3 form an open container.

[0085] Figure 2 Shows Figure 1 In the cooker 1, the handle 4 is in the stowed position. As shown in the figure, the full length of the handle 4 extends lying on the main body 2 and is parallel to the bottom 3.

[0086] like Figure 3 As shown, the proximal end of the handle 4 is rotatably fixed to the outer wall 5 of the main body 2 through a connecting portion 6. The handle 4 is rotatably connected to the connecting portion 6 through an axis bolt 7, which extends through the connecting portion 6 along a rotation axis that crosses the connecting portion 6. The axis bolt 7 allows the handle 4 to rotate vertically in a direction perpendicular to the main body 2 of the cooker 1.

[0087] The handle 4 includes a cavity 8 having a locking assembly located therein. The locking assembly includes a locking member 9 configured to move between a first locked position and a second unlocked position.

[0088] like Figure 3As shown, when the locking member 9 is in the first locking position, the angled upper surface 17 of the proximal end of the locking member 9 rigidly engages a first contact point 11 located on an acute angled upper surface 16 of a concave portion 10 of the connecting portion 6, and a second contact point 12 located on the proximal lower surface of the cavity 8. The lower surface 19 of the proximal end of the locking member 9 engages the second contact point 12. The distal end of the locking member 9 includes a protrusion 18, which engages a third contact point 13 located on the distal upper surface of the cavity 8 when the locking member 9 is in the first locking position.

[0089] The rigid engagement of the locking member 9 with the first, second and third contact points 11, 12, 13 prevents rotation of the handle 4 when a rotational force is applied. Advantageously, the rigid engagement of the locking member 9 with all three contact points 11, 12, 13 in the first locking position ensures that the handle 4 is rigidly fixed in the working position and / or the stowed position even when the individual components of the handle have varying dimensions due to manufacturing tolerances.

[0090] The locking assembly also includes a trigger 14 located on the underside of the handle 4, which is integral with the locking member 9. In use, the user can move the locking member 9 from the first locking position to the second unlocking position by pulling the trigger 14 in a direction toward the distal end of the handle 4.

[0091] The locking member 9 is resiliently biased to the first locking position by a spring 15 located at the distal end of the cavity 8 .

[0092] like Figure 4 As shown, when the locking member 9 is in the second unlocked position, the locking member 9 is retracted toward the distal end of the handle 4. In doing so, the proximal end of the locking member 9 is withdrawn from the recessed portion 10 of the connecting portion 6, and the proximal end of the locking member 9 does not rigidly engage the first, second and third contact points 11, 12, 13. When a rotational force is applied to the handle 4, the handle 4 can be freely rotated vertically to the stowed and / or working position.

[0093] like Figure 5 As shown, the upper surface 17 of the proximal end of the locking member 9 has an angle of about 17° relative to the plane of the handle 4. The upper surface 16 of the concave portion of the connecting portion 6 includes an acute surface 16 having an angle of about 17° relative to the plane of the handle 4. This ensures that the proximal end of the locking member 9 can enter the concave portion 10 of the connecting portion 6 until it rigidly engages the upper surface 16 of the concave portion at the first contact point 11.

[0094] In use, when the trigger 14 is pulled toward the distal end of the handle 4, the locking member 9 moves from its first locking position in which it engages the first, second and third contact points 11, 12, 13 to a second unlocked position in which it does not engage the first, second and third contact points 11, 12, 13. This unlocks the handle 4 and allows the user to move the handle 4 between the working position and the stowed position when a rotational force is applied in a direction perpendicular to the body 2 of the cooker 1. When the handle 4 reaches the working and / or stowed position, the user can release the handle 4, which causes the locking member 9 to move from the second unlocked position to the first locked position by the expansion of the spring 15. This causes the locking member 9 to be pushed toward the proximal end of the handle 4 and into the recessed portion 10 of the connecting portion 6 until the upper surface 17 of the proximal end of the locking member 9 encounters resistance on the upper surface 16 of the recessed portion 10 of the connecting portion 6 at the first contact point 11. In this position, the lower surface 19 of the proximal end of the locking member 9 rigidly engages the second contact point 12, and the protrusion 18 on the distal end of the locking member 9 rigidly engages the third contact point 13. This prevents the handle 4 from rotating when a rotational force is applied in a direction perpendicular to the body 2 of the pan 1. Furthermore, when the locking member 9 is in the locked position, the handle 4 is rigidly fixed in the stowed and / or operative position and there is little movement of the handle 4 when a user applies vertical, rotational and lateral forces to the handle 4. This may be perceived by some users as higher quality and / or more expensive.

[0095] The cooking utensils described in the above embodiments can be a frying pan or other pots, for example, a boiling pot, a frying pan, a wok, etc.

[0096] like Figure 6 As shown, in order to improve the convenience of placement, the utility model has a set consisting of two pans. The main body 72 of the larger pan 71 has a greater depth and diameter than the main body 62 of the smaller pan 61.

[0097] The body 62 of the smaller pan 61 is positioned within the body 72 of the larger pan 71, and the handle 74 of the larger pan 71 and the handle 64 of the smaller pan 61 extend substantially parallel to their bottoms 63, 73 lying on the bodies 62, 72 of the pans 61, 71. The handle 74 of the larger pan 71 is aligned with and disposed above the handle 64 of the smaller pan 61.

[0098] To nest the pans, the bottom 63 of the smaller pan 61 is placed on the bottom 73 of the larger pan 71 with the handle 64 of the smaller pan 61 in the stowed position. The handle 74 of the larger pan 71 is then moved to the stowed position so that the handle 74 extends over the bodies 62, 72 of the pans 61, 71 and the handle 71 of the larger pan is aligned with and directly above the handle 64 of the smaller pan.

[0099] Similarly, if Figure 7 As shown, in order to improve the convenience of storage, more than one pot of the present invention can be nested. The body of the first pot 81 has a greater depth and diameter than the body of the second pot 71, and the body 71 of the second pot has a deeper depth and a larger diameter than the body of the third pot 61.

[0100] The body of the third pot 61 is positioned within the body of the second pot 71, and the body 71 of the second pot is positioned within the body of the first pot 81. The handle 84 of the first pot 81, the handle 74 of the second pot 71, and the handle 64 of the third pot 61 extend substantially parallel to their bottoms 63, 73, 83 lying on the bodies of the pots 62, 72, 82. The handle 84 of the first pot 81 is aligned with and arranged above the handle 74 of the second pot 71, and the handle 74 of the second pot 71 is aligned with and arranged above the handle 64 of the third pot 61.

[0101] To nest the pots, the bottom 63 of the smallest third pot 61 is placed on the bottom 73 of the larger second pot 71, with the handle 64 of the smaller third pot 61 in the stowed position. The handle 74 of the larger second pot 71 is then moved to the stowed position so that its handle 74 extends over its body 72 and the body 62 of the third pot, and the handle of the larger second pot 72 is aligned with the handle 64 of the smaller third pot 61 and is disposed directly above it. The bottom 73 of the larger second pot 71 is then placed on the bottom 83 of the largest first pot 81. The handle 84 of the largest first pot 81 is then moved to the stowed position so that its handle 84 extends over the bodies 62, 72, 82 of the respective pots 61, 71, 81, and the handle 84 of the largest first pot 81 is aligned with the handle 74 of the smaller second pot 71 and is disposed directly above it.

[0102] One or more embodiments have been described above by way of example only. Many variations are possible without departing from the scope of protection provided by the appended claims.
