Description

Technical Field

[0001] The invention relates to a cooking utensil and accessories thereof similar to pots, cookers or containers, in particular to a folding handle of the cooking utensil. Background Art

[0002] Existing cooking utensils such as pots and pans primarily include a pot body, a connecting base mounted on the pot body, and a handle mounted on the connecting base. The handle is typically secured to the connecting base by bolts or other means, while the connecting base is typically welded or secured to the pot body, taking up a large amount of space and making it inconvenient to carry, store, and pack. To facilitate storage and portability when not in use, the handle is subsequently designed to be detachable. However, existing handle detachable structures are also relatively complex, with most having a switch button mounted on the handle and a complex elastic lock mechanism installed inside the handle. The switch button controls the connection and disconnection of the elastic lock from the pot body, making assembly cumbersome and inconvenient to replace damaged internal parts.

[0003] Chinese patent CN206473166U discloses a pot with a rotatable handle, comprising a pot body and a handle seat arranged on one side of the pot body, a pot handle being arranged on the handle seat, a fixed platform being provided, a rotating hole being provided at one end of the pot handle, which is rotatably matched with the fixed platform, a limiting structure being provided between the fixed platform and the pot handle, the fixed platform being provided with a groove, a button being provided in the groove, a clamping block being connected below the button, a spring being provided below the clamping block, a first clamping slot being provided in the groove which is matched with the clamping block, a second clamping slot being provided in the rotating hole of the pot handle which is matched with the clamping block, when the pot handle rotates, when the second clamping slot coincides with the first clamping slot, the clamping block enters the second clamping slot, the pot handle is unfolded and fixed, and is in a working state that can be held in hand; when the button is pressed, the clamping block is disengaged from the second clamping slot, and the pot handle can be rotated toward the upper surface of the pot body, a locking block is provided at the other end of the pot handle, and a locking groove is provided on the outer peripheral wall of the pot body, when the pot handle rotates to the pot surface, the locking block is inserted into the locking groove, and the pot handle is retracted onto the pot surface.

[0004] This technical solution allows the pot handle to be retracted onto the pot surface without being disassembled, solving the problem of the large space occupied by the fixed pot handle. However, since the pot handle is higher than the pot surface, this structure poses a challenge to the user's cooking habits. At the same time, the combination of this fixing platform and the rotating hole results in a large gap between the pot handle and the fixing platform, resulting in severe shaking and instability during use.

[0005] Chinese patent CN222549090U discloses a cooker and a cooker set, wherein the handle is vertically rotatable between a first working position and a second stowed position, wherein a cavity within the handle comprises a locking assembly, the locking assembly including a locking member, the proximal end of the locking member including an upper surface at an acute angle relative to the plane of the handle, and a connecting portion including a recessed portion 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 acute angled upper surface of the connecting portion, the recessed portion being located on the underside of the connecting portion and cooperating with the proximal end of the locking member. In short, the technical solution is to provide a recessed portion on the connecting portion and a protruding portion on the proximal end of the handle, wherein the protruding portion is inserted into the recessed portion when the handle is unfolded; and when the protruding portion is withdrawn from the recessed portion, the handle can be folded relative to the connecting portion.

[0006] The above technical solution eliminates the need to remove the handle when placing the cookware, utilizing the space inside the cookware by folding it. However, during use, the strength of the connection between the protrusion and the recess presents risks. In particular, if the material strength of the protrusion is insufficient, it is prone to breakage, which poses a safety hazard for the cookware. Furthermore, the connection between the protrusion and the recess must be very tight; otherwise, the gap will be too large, resulting in significant shaking during use. However, if the protrusion and the recess are tightly connected, it will be difficult to operate the protrusion to withdraw from the recess when the handle needs to be folded. Therefore, this technical solution cannot achieve both stability and ease of use.

[0007] The above-mentioned existing technology has very high requirements for manufacturing precision. As stated in the patent, the combination of the protrusion and the recess has high requirements for the angle of the joint surface. Otherwise, the protrusion will not easily enter the recess when the handle is unfolded, or the gap between the protrusion and the recess is too large, and shaking is inevitable during use. Summary of the Invention

[0008] The object of the present invention is to provide a foldable handle for a cooking utensil, which solves the shortcomings of existing foldable handles, such as excessively high requirements on material strength, inconvenient operation, and easy shaking during use.

[0009] To achieve the above object, the technical solution of the present invention is: A foldable handle for a cooking utensil, comprising a connecting member and a handle, the handle being rotatably connected to the connecting member, the handle having a stowed position folded above the connecting member and a working position extended relative to the connecting member; The connecting component includes a mounting seat, a pivot seat, and a clamping seat connected in sequence; the front end of the handle has extended pivot arms on both sides, and the pivot arms are rotatably connected to the pivot seat; the front end of the handle is provided with a mounting cavity, and a locking assembly is provided in the mounting cavity, and the locking assembly includes a locking piece, a driving piece, and an elastic piece; the driving piece is operated to drive the locking piece to extend out of the mounting cavity, and the elastic piece maintains the elastic force that drives the locking piece to return to the mounting cavity; The mounting cavity of the handle also includes a packaging plate, and the locking assembly is arranged in the space formed by the mounting cavity and the packaging plate; the packaging plate includes a vertical limit plate and a horizontal cover plate; The locking member includes a hook portion and a connecting portion; the connecting portion is connected to the driving member; the elastic member is compressed and arranged between the connecting portion and the limiting plate, and the two ends of the elastic member are respectively against or connected to the limiting plate and the connecting portion; When the connecting seat is engaged with the hook portion to form a mutually hooked state, the handle is locked with the connecting component and is in the working position; when the connecting seat is disengaged from the hook portion, the handle is folded on the upper part of the connecting component and is in the retracted position.

[0010] A sliding hole for the driving member to move is provided on the upper surface of the mounting cavity at the front end of the handle, and the connecting portion of the locking member is box-shaped; the driving member includes an operating portion and an insertion portion, which are connected to each other, the operating portion protruding from the upper surface of the handle, the insertion portion extending into the mounting cavity through the sliding hole, and inserted into the connecting portion of the locking member, the driving member slides in the sliding hole to drive the locking and disengagement of the locking member and the card seat.

[0011] The cross section of the clamping seat is a right-angled trapezoid, and the contact surface between the clamping seat and the outer side of the hook portion of the locking piece is an inclined surface; The hook portion of the locking piece is hook-shaped, including a hook tip, a hook bend and a hook handle. The hook handle is connected to the connecting part. The hook bend is the space where the snap-in seat enters the locking piece and locks it. The outer side surface of the hook tip is an inclined surface, which is arranged opposite to the inclined surface of the snap-in seat, and the angles of the two inclined surfaces are the same; the contact surface between the hook bend and the snap-in seat is a plane, and when the snap-in seat enters the hook bend, it forms a hooked state with the hook portion.

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings, which are for illustrative purposes only and are not to be construed as limiting the present invention.

[0018] To more concisely illustrate this embodiment, some components well known to those skilled in the art but not relevant to the main content of this invention may be omitted from the drawings or descriptions. In addition, for ease of description, some components may be omitted, enlarged, or reduced in size in the drawings, but they do not represent the dimensions or entire structure of the actual product.

[0019] The present invention discloses a foldable handle for a cooking utensil, such as Figure 1-5 As shown, it includes a connecting part 1 and a handle 2, as shown in FIG. Figure 1 As shown, the connecting component 1 includes a mounting seat 11, a pivot seat 12 and a clamping seat 13, and the mounting seat 11 is fixedly connected to the cooking utensil; the handle 2 has extended pivot arms 21 on both sides of the front end, and the pivot arms 21 of the handle 2 are rotatably connected to the pivot seat 12 of the connecting component 1; Figure 3 and Figure 5 As shown, the handle 2 rotates between a stowed position folded above the connecting member 1 and a working position unfolded relative to the connecting member 1; ie, Figure 5 As shown, the handle 2 can be folded onto the upper surface of the cooking utensil.

[0020] like Figure 1 、 Figure 2 As shown, a mounting cavity 22 is provided at the front end of the handle 2 , and a locking assembly is provided in the mounting cavity 22 . The locking assembly includes a locking member 3 , a driving member 4 and an elastic member 5 .

[0021] like Figure 1-3 As shown, the mounting cavity 22 of the handle 2 also includes a packaging plate 6, and the locking assembly is arranged in the space formed by the mounting cavity 22 and the packaging plate 6; the packaging plate 6 includes a vertical limit plate 61 and a horizontal cover plate 62. Preferably, the limit plate 61 is connected to the cover plate 62 at a right angle.

[0022] The locking member 3 includes a hook portion 31 and a connecting portion 32; the connecting portion 32 is connected to the driving member 4; the elastic member 5 is compressed and arranged between the connecting portion 32 and the limiting plate 61, and the two ends of the elastic member 5 are respectively against or connected to the limiting plate 61 and the connecting portion 32.

[0023] The operating drive member 4 drives the locking member 3 to extend out of the installation cavity 22, so that the locking member 3 is disengaged from the clamping seat 13; since the elastic member 5 is arranged between the connecting portion 32 and the limiting plate 61 and remains in a compressed state, the elastic force that drives the locking member 3 to return to the installation cavity 22 is always maintained, which also makes the locking member 3 and the clamping seat 13 hooked and connected very firmly.

[0024] When the connecting seat 13 is engaged with the hook portion 31 to form a mutually hooked state, the handle 2 is locked with the connecting component 1 and the handle 2 is in the working position; when the connecting seat 13 is disengaged from the hook portion 31, the handle 2 is folded to the upper part of the connecting component 1 and the handle 2 is in the retracted position.

[0025] Furthermore, if Figure 1-4 As shown, the upper surface of the mounting cavity 22 at the front end of the handle 2 is provided with a sliding hole 23 for the movement of the driving member 4, and the connecting portion 32 of the locking member 3 is box-shaped. The box-shaped setting of the connecting portion 32 is used to match the space of the mounting cavity 22. The box-shaped setting prevents the locking member 3 from shaking left and right in the mounting cavity 22, which is a factor in maintaining the stability of the handle 2 when in use.

[0026] The driving member 4 includes an operating part 41 and an insertion part 42, which are connected to each other. The operating part 41 protrudes from the upper surface of the handle 2, and the insertion part 42 extends into the installation cavity 22 through the sliding hole 23. The insertion part 42 is inserted into the connecting part 32 of the locking member 3. The driving member 4 slides in the sliding hole 23 to drive the locking and disengagement of the locking member 3 and the card seat 13.

[0027] like Figure 2-5 As shown, the cross section of the clamping seat 12 is a right-angled trapezoid, and the contact surface between the clamping seat 13 and the hook portion 31 of the locking member 3 is an inclined surface; Furthermore, if Figure 2 As shown, the hook portion 31 of the locking member 3 is hook-shaped and includes a hook tip 311, a hook bend 312, and a hook handle 313. The hook handle 313 is connected to the connecting portion 32. The hook bend 312 provides a space for the connector 13 to enter and lock the locking member 3. The outer surface of the hook tip 311, which contacts the connector 13, is also configured as an inclined surface, facing the inclined surface of the connector 13, and the two inclined surfaces have the same angle. When the handle 2 is extended to the working position, the inclined surface of the connector 13 serves as a guide for the hook tip 311 to slide, making the rotation of the handle 2 less laborious.

[0028] The contact surface between the hook bend 312 and the clamping seat 13 is a plane. When the clamping seat 13 enters the hook bend 312, the planes of the two coincide with each other, and the clamping seat 13 and the hook portion 31 form a stable mutual hook state. Under the combined action of the elastic force of the elastic member 5 and the gravity of the cooking utensil, the mutual hook between the two will become tighter and tighter, which is the main design point to ensure the stability of the handle 2 when in use.

[0029] A channel 24 for the hook handle 313 of the hook portion 31 to move is provided between the limiting plate 61 and the upper surface of the handle 2. The channel 24 is both a channel for the movement of the hook handle 313 and also has the function of limiting and supporting the upper and lower positions of the hook handle 313. The gap between the channel 24 and the hook handle 313 must be strictly controlled. This is one of the control factors to prevent the handle 2 from shaking up and down when in use.

[0030] Furthermore, an elastic member 5 is disposed below the hook handle 313 and between the stop plate 61 and the connecting portion 31 of the locking member 3. A return spring is typically used as the elastic member 5. The cover plate 62 of the packaging plate 6 is provided with screw holes, through which bolts are passed to secure the packaging plate 6 to the handle 2.

[0031] When handle 2 is Figure 5 The stowed position Figure 3 When turning the extended working position, turn to Figure 4 When the latch 31 is in the unlocked position, the outer side surface of the hook tip 311 contacts the inclined surface of the card seat 13, and the handle 2 is continuously rotated, and the hook tip 311 slides down along the inclined surface of the card seat 13, pulling the hook handle 313 from the channel 24 to extend in the direction of the connecting component 1 outside the installation cavity 22, and the elastic member 5 is squeezed and contracted. When the hook tip 311 slides to the end of the inclined surface of the card seat 13 and disengages from the card seat 13, the squeezing force on the elastic member 5 suddenly disappears, and the elastic member 5 opens instantly, driving the connecting portion 32 of the locking member 3 to reset into the installation cavity 22. In this way, the card seat 13 enters the hook bend 312 of the hook portion 31, and the card seat 13 and the hook portion 31 form a mutually hooked state, the handle 2 is locked with the connecting component 1, and the handle 2 is fixed as shown in FIG. Figure 3 The outer surface of the hook tip 311 of the hook portion 31 and the contact surface of the clamping seat 13 are designed to be inclined, making the handle 2 very convenient and labor-saving to unfold. The hook bend 312 coincides with the contact plane of the clamping seat 13, and the clamping seat 13 and the hook portion 31 form a stable mutual hook state. Under the elastic force of the elastic member 5 and the gravity of the cooking utensil, the mutual hook of the two will become increasingly tight, ensuring that the handle 2 is stable and does not shake when in use.

[0032] Of course, when handle 2 is turned to Figure 4 When the handle 2 is in the position shown, the operating portion 41 of the driving member 4 can be pushed with a finger to push the locking member 3 until the hook tip 311 thereof slides over the end of the inclined surface of the clamping seat 13. Then, the locking member 3 is reset into the mounting cavity 22 under the elastic force of the elastic member 5. The clamping seat 13 enters the hook bend 312 of the hook portion 31, and the handle 2 is fixed as shown. Figure 3 Expanded working position.

[0033] To make handle 2 Figure 3 The working position is rotated to Figure 5 To retract the handle 2 from the mounting cavity 22, the locking member 3 is moved toward the mounting cavity 22, and the locking member 3 is moved toward the mounting cavity 22. The locking member 3 is then .... Figure 5 In the stowed position shown, the handle 2 is folded over the upper part of the connecting part 1 and stowed.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application of the present invention should fall within the technical scope of the present invention.
