Description

Technology Field

[0001] The present invention relates to a cooking tool, and more specifically, to a cooking tool in which the head portion can be separated and replaced. Background Technology

[0002] Cooking tools such as spatulas and ladles, having been developed in the early stages of human history, have simple structures and typically feature long handles. While these long handles offer advantages in terms of hygiene and safety by allowing the user to maintain a certain distance from the food being cooked and the stove, they can also simultaneously act as a source of inconvenience in various ways.

[0003] For example, a long handle makes the cooking tool cumbersome in size and shape, making storage inconvenient. This is especially true when the cooking end of the handle takes the form of a ladle or spatula, which has a shape completely different from the handle itself.

[0004] In addition, it is necessary to disinfect cooking utensils for hygienic use, but with general cooking utensils, the long handle must be disinfected along with the cooking surface. If a user wishes to disinfect a cooking utensil in boiling water, they face the inconvenience of having to prepare a very large pot capable of containing both the handle and the cooking surface. This situation can be particularly inconvenient, considering that the handle does not get as dirty as the cooking surface and does not require the same level of cleanliness, so it does not need to be disinfected in the same way.

[0005] Conventional cooking utensils are made from various materials, and products made of stainless steel, silicone, nylon resin, and wood are available on the market. Depending on the material, each cooking utensil offers a different user experience, and consumers select and purchase products with the feel they prefer according to their individual tastes.

[0006] However, cooking utensils frequently come into contact with the surface of containers heated to high temperatures, such as frying pans and pots. If the cooking utensils are made of metal materials such as stainless steel, there is a high risk of damaging the coating applied to the surface of the container. Additionally, if the cooking utensils are made of materials such as synthetic resin, there is a risk that parts of the utensil may melt due to the heat applied during cooking, and even if their shape does not deform significantly, there is a risk that harmful substances, such as endocrine disruptors, may be mixed into the cooked food. Although there are synthetic resin materials that do not emit harmful substances even at high temperatures, using them may increase the manufacturing cost of the product.

[0007] To resolve the aforementioned inconveniences, cooking tools have been developed in which the head, corresponding to the cooking portion, is detachably configured to the handle. Such tools offer the advantage of convenient storage and cleaning. However, in cooking tools based on the prior art where the head is detachably attached to the handle, there is a problem in that food particles, seasonings, etc., easily penetrate the joint between the head and the handle. This compromises the hygiene of the tool and causes problems such as altering the taste of the food being cooked or handled with the tool. Furthermore, foreign substances penetrating the joint can interfere with a secure interlock or cause wear on the joint area, potentially loosening the connection between the head and the handle and causing the head to unintentionally detach from the handle, which could lead to serious safety accidents. The problem to be solved

[0008] Therefore, the present invention is derived to solve the aforementioned problems, and one aspect of the present invention is to provide a cooking tool having a detachable head that allows the handle shaft and the head to maintain a rigid connection.

[0009] Other objects of the present invention will become more apparent through the embodiments described below. means of solving the problem

[0010] A separable cooking tool according to one aspect of the present invention may include: a handle shaft extending along the longitudinal direction having a first coupling part having a coupling hole formed therein; a head coupled to the handle shaft having a second coupling part having a coupling hole formed therein, wherein the second coupling part overlaps with the first coupling part and the coupling hole of the second coupling part is aligned with the coupling hole of the first coupling part; a fixing pin inserted into the coupling hole of the first coupling part and the coupling hole of the second coupling part; and a clip that fixes the fixing pin so that the fixing pin does not detach from the coupling hole of the first coupling part and the coupling hole of the second coupling part. Here, either of the first coupling part and the second coupling part may be an outer coupling part having a sleeve shape, and the other of the first coupling part and the second coupling part may be an inner coupling part inserted into the inner side of the outer coupling part.

[0011] The detachable cooking tool according to the present invention may have one or more of the following embodiments. For example, the clip may have a curved shape including two clip ends and may apply an elastic force to the two clip ends in a direction toward each other.

[0012] With the fixing pin inserted to pass through both the coupling hole of the inner coupling part and the coupling hole of the outer coupling part, the end of the fixing pin may be located on the outside of the outer coupling part, and the clip end may be coupled to cover the end of the fixing pin.

[0013] Two coupling holes may be formed in the outer coupling portion, and when the fixing pin is inserted to pass through both the coupling hole of the inner coupling portion and the coupling hole of the outer coupling portion, both ends of the fixing pin may be located on the outer side of the outer coupling portion at different points. In a structure in which the fixing pin is inserted as described above, a stopper that cannot pass through the coupling hole of the outer coupling portion may be formed at one end of the fixing pin, and a locking groove configured to engage with the clip may be formed at the other end of the fixing pin.

[0014] The above fixing pin may form part of the clip. The clip may have a bent shape including two fixing pins and a connecting portion connecting the two fixing pins, and as the clip is joined in a transverse direction intersecting the longitudinal direction, each of the two fixing pins may be inserted in the transverse direction into the joining hole of the outer joining portion and the joining hole of the inner joining portion.

[0015] The clip may be coupled to the outer side of the outer coupling portion so as to be movable along the longitudinal direction. When the fixing pin is inserted to pass through both the coupling hole of the inner coupling portion and the coupling hole of the outer coupling portion, and the end of the fixing pin is configured to be located on the outer side of the outer coupling portion, the end of the fixing pin may be located on the outer side of the outer coupling portion, and a fixing groove may be formed on the inner side of the clip, extending along the longitudinal direction and having a width corresponding to the thickness of the end of the fixing pin.

[0016] The clip may include a support projection that protrudes in a direction intersecting the length direction.

[0017] The head may include a plurality of replacement heads. Each of the plurality of replacement heads may have the second coupling portion, and a selected replacement head among the plurality of replacement heads may be coupled to the handle shaft. Effects of the invention

[0018] According to the means for solving the problem of the present invention as described above, various effects including the following can be expected. However, the present invention is not required to exhibit all of the following effects to be valid.

[0019] In a detachable cooking utensil according to some embodiments of the present invention, a fixing pin is inserted into a coupling hole of an inner coupling part and an outer coupling part to firmly connect the handle shaft and the head, and a clip can prevent the fixing pin from coming out of its position. This structure can increase user convenience by allowing the head to be firmly connected to the handle shaft when connection of the head is required, while allowing the user to easily detach the head when separation is required for cleaning, etc.

[0020] In addition, in a separable cooking tool according to some embodiments of the present invention, a clip can prevent foreign substances from entering the coupling hole. This can prevent food particles or other substances from causing bacterial growth in the coupling hole, and can prevent the coupling between the inner and outer coupling parts and the fixing pin from becoming loose or the contact area from wearing out due to foreign substances.

[0021] In addition, in a detachable cooking tool according to some embodiments of the present invention, the head may include a plurality of replacement heads, and the user may select a replacement head having a food contact portion of the desired shape and attach it to the handle shaft. This provides the advantage of being able to use various types of cooking tools while significantly reducing the space required to store these tools. Brief explanation of the drawing

[0027] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0028] FIGS. 1 and FIGS. 2 are an exemplary perspective view and an exploded perspective view illustrating a detachable cooking tool (1100) according to a first embodiment of the present invention, and FIG. 3 is an exemplary perspective view illustrating a clip (500) of the detachable cooking tool (1100). Referring to FIGS. 1 to 3, the detachable cooking tool (1100) according to the first embodiment of the present invention may largely include a handle shaft (100), a head (200), a fixing pin (300), and a clip (500).

[0029] The handle shaft (100) is a part that extends along the longitudinal direction and has an elongated shape, and corresponds to the part that the user holds in their hand when using the cooking tool (1100). The handle shaft (100) may include a handle body (110) and a first connecting part (120).

[0030] The handle body (110) may have an elongated shape as a main part of the handle shaft (100) and corresponds to the part that the user directly grips.

[0031] The first coupling portion (120) may be formed at the end of the handle body (110) and configured to be coupled to the second coupling portion (220) of the head (200). To this end, a first coupling hole (130) may be formed in the first coupling portion (120).

[0032] The head (200) can be used by being coupled to the end of the handle shaft (100) and corresponds to the part that comes into contact with food when the user cooks or handles food using the cooking tool (1100). The head (200) may basically include a food contact part (210) and a second coupling part (220).

[0033] The food contact portion (210) is a main part of the head (200) and may have a shape corresponding to various cooking tools. For example, the detachable cooking tool (1100) shown in FIG. 2 includes a plurality of heads (200a, 200b), and their food contact portions (210) each have a shape corresponding to a spatula and a ladle. In this way, when the detachable cooking tool (1100) includes a plurality of heads (200a, 200b), the head (200) may be described as including a plurality of replacement heads (200a, 200b). That is, the detachable cooking tool (1100) may include a plurality of replacement heads (200a, 200b). When the head (200) includes a plurality of replacement heads (200a, 200b), each replacement head (200a, 200b) may be formed with a different size and / or shape of the food contact portion (210), and the second coupling portion (220) may be formed with the same size and shape.

[0034] The second coupling portion (220) may be formed on one side of the food contact portion (210) and configured to be coupled to the first coupling portion (120) of the handle shaft (100). To this end, a second coupling hole (230) may be formed in the second coupling portion (220).

[0035] Of the first coupling part (120) provided on the handle shaft (100) and the second coupling part (220) provided on the head (200), one may form an outer coupling part and the other may form an inner coupling part. The outer coupling part may have a sleeve shape and an insertion space may be formed on the inside thereof, and the inner coupling part may be inserted into this insertion space. That is, in some embodiments of the present invention, the coupling part (120) provided on the handle shaft (100) may be implemented in the form of an outer coupling part and the coupling part (220) provided on the head (200) may be implemented in the form of an inner coupling part, whereas in some other embodiments of the present invention, the coupling part (220) provided on the head (200) may be implemented in the form of an outer coupling part and the coupling part (120) provided on the handle shaft (100) may be implemented in the form of an inner coupling part.

[0036] For example, in the examples illustrated in FIGS. 2, 4 and 6, the second coupling part (220) provided in the head (200) is implemented in the form of an outer coupling part, and the first coupling part (120) provided in the handle shaft (100) is implemented in the form of an inner coupling part. In these embodiments, the coupling part (220) of the head (200) has a sleeve shape so that an insertion space (250) is formed on the inside thereof, and the coupling part (120) of the handle shaft (100) may be configured as an inner coupling part having a cross-section and size corresponding to the insertion space (250) so that it can be inserted into the insertion space (250).

[0037] Conversely, in the example illustrated in FIG. 7, the first coupling part (120) provided on the handle shaft (100) is implemented in the form of an outer coupling part, and the second coupling part (220) provided on the head (200) is implemented in the form of an inner coupling part. In these embodiments, the coupling part (120) of the handle shaft (100) has a sleeve shape so that an insertion space (150) is formed on the inside thereof, and the coupling part (220) of the head (200) may be configured as an inner coupling part having a cross-section and size corresponding to the insertion space (150) so that it can be inserted into the insertion space (150).

[0038] Referring again to FIG. 2, the outer coupling part (220) (the second coupling part (220) provided on the head (200)) may have an insertion space (250) formed on its inner side and may have the shape of a sleeve. The depth and cross-section of the insertion space (250) may correspond to the length and cross-section of the inner coupling part (120) (the first coupling part (120) provided on the handle shaft (100)).

[0039] As illustrated in FIG. 2, it may be preferable for the insertion space (250) and the inner coupling part (120) to have a cross-section that is not circular. This allows the inner coupling part (120) to be inserted in a state where it is aligned relative to the outer coupling part (220), and also prevents the inner coupling part (120) from rotating arbitrarily while it is inserted into the insertion space (250).

[0040] The coupling hole (130) formed in the inner coupling portion (120) may be formed in a direction perpendicular to the longitudinal direction (the direction in which the handle body (110) extends). The coupling hole (130) may be formed in the form of a through hole penetrating the inner coupling portion (120) or in the form of a blind hole that is open to only one side. Depending on the material of the handle shaft (100), the inner coupling portion (120) may also be formed in a hollow form; in this case, the coupling hole (130) may penetrate the entire inner coupling portion (120) or penetrate only one side of the inner coupling portion (120).

[0041] The coupling hole (230) formed in the outer coupling part (220) may also be formed in a direction perpendicular to the longitudinal direction (the direction in which the handle body (110) is extended). The outer coupling part (220) may be implemented in the form of a sleeve, and two coupling holes (230) may be formed on both sides of the insertion space (250) by penetrating the entire outer coupling part (220), or only one coupling hole (230) may be formed on one side of the insertion space (250) by penetrating only one side of the outer coupling part (220).

[0042] The inner coupling part (120) can be inserted into the insertion space (250) such that the inner coupling part (120) overlaps with the outer coupling part (220) and the coupling hole (130) of the inner coupling part (120) is aligned with the coupling hole (230) of the outer coupling part (220). When the insertion space (250) and the inner coupling part (120) have a cross-section that is not circular, the inner coupling part (120) and the outer coupling part (220) overlap and the coupling hole (130) of the inner coupling part (120) is aligned with the coupling hole (230) of the outer coupling part (220) simply by inserting the inner coupling part (120) into the insertion space (250).

[0043] In one embodiment of the present invention, a mounting groove (240) may be formed on the outer surface of the outer coupling portion (120). The mounting groove (240) corresponds to the portion where the clip (500) is mounted, and may be formed with a shape and size corresponding to at least a portion of the clip (500). As shown in FIG. 2, a coupling hole (230) may be formed in the area where the mounting groove (240) is formed.

[0044] A fixing pin (300) is a component that is inserted into the coupling hole (130) of the first coupling part (120) and the coupling hole (230) of the second coupling part (220) to connect the first coupling part (120) and the second coupling part (220) to each other. The fixing pin (300) may correspond to, for example, a straight pin member (310), but may be implemented in a curved shape as needed. The pin member (310) may be manufactured in a simple shape having a circular cross-section as shown in FIG. 2. Of course, in some embodiments of the present invention, the pin member (310) may have a cross-section of a shape other than a circle. Also, while FIG. 2 depicts a detachable cooking tool (1100) including one fixing pin (300), the detachable cooking tool (1100) may include a plurality of fixing pins (300).

[0045] According to one embodiment of the present invention, the fixing pin (300) may be formed with a length such that the end (330) of the fixing pin (300) is positioned on the outside of the outer coupling part (220) while inserted into the coupling holes (130, 230) of the inner coupling part (120) and the outer coupling part (220).

[0046] For example, when a coupling hole (130) formed in the inner coupling part (120) penetrates the entire inner coupling part (120) and a coupling hole (230) formed in the outer coupling part (220) also penetrates the entire outer coupling part (220) so that two coupling holes (230) are formed on both sides of the insertion space (250), a fixing pin (300) is inserted to pass through both the coupling holes (130, 230) of the inner coupling part (120) and the outer coupling part (220), so that one end of the fixing pin (300) is located outside the coupling groove (230) on one side of the outer coupling part (220) and the other end of the fixing pin (300) is located outside the coupling groove (230) on the other side of the outer coupling part (220).

[0047] As another example, in the case where the coupling hole (130) formed in the inner coupling part (120) is a blind hole and is open only to one side of the inner coupling part (120), and the coupling hole (230) formed in the outer coupling part (220) is formed only to one side of the insertion space (250), the fixing pin (300) can be inserted into both the coupling holes (130, 230) of the inner coupling part (120) and the outer coupling part (220), so that one end of the fixing pin (300) is located inside the coupling groove (130) of the inner coupling part (120) and the other end of the fixing pin (300) is located outside the coupling groove (230) of the outer coupling part (220).

[0048] The end (330) of the fixing pin (300) does not necessarily have to be located on the outside of the outer coupling part (220) (i.e., outside the coupling hole (230)). However, even in this case, it may be advantageous to configure the end (330) of the fixing pin (300) to contact the clip (500) mounted on the outer coupling part (220).

[0049] The clip (500) fixes the fixing pin (300) so that the fixing pin (300) does not detach from the coupling hole (130, 230) of the inner coupling part (120) and the outer coupling part (220), while covering the coupling hole (230) of the outer coupling part (220) into which the fixing pin (300) is inserted to block foreign matter from entering the coupling hole (230).

[0050] The clip (500) illustrated in FIG. 2 is formed in a bent shape including two clip ends (520). The concept that the clip (500) has a bent shape encompasses not only the case where the clip (500) has a shape corresponding to a "C" as in FIG. 2, but also shapes including various bends and / or curves.

[0051] The clip (500) may have the form of, for example, a leaf spring or a plate spring, and may apply an elastic force to the two clip ends (520) in a direction toward each other. That is, the elastic force of the clip (500) may cause the clip ends (520) on both sides to be pressed toward each other around the connecting part (510).

[0052] With the fixing pin (300) inserted into the coupling holes (130, 230) of the inner coupling part (120) and the outer coupling part (220), the clip (500) can be mounted on the outer side of the outer coupling part (220), and in particular, can be mounted to cover the coupling hole (230) of the outer coupling part (220). In the example illustrated in FIG. 2, the clip (500) is mounted in a mounting groove (240) formed on the outer circumference of the outer coupling part (220). When the depth of the mounting groove (240) corresponds to the thickness of the clip (500), the outer surface of the clip (500) can be continuously connected to the outer surface of the outer coupling part (220) while the clip (500) is mounted.

[0053] FIG. 3 is a perspective view illustrating several shapes that a clip (500) of a detachable cooking tool (1100) according to a first embodiment of the present invention may take. A detachable cooking tool (1100) according to an embodiment of the present invention may include only one of the clips (500a to 500d) shown in FIG. 3, or it may include multiple clips (500a to 500d) shown in FIG. 3. When the detachable cooking tool (1100) includes a plurality of clips (500a to 500d), the user may select a preferred clip (500a to 500d) as needed and attach it to an outer coupling part (220).

[0054] The clip (500a) illustrated in FIG. 3(a) has a shape similar to the clip (500) illustrated in FIG. 2 and includes a connecting portion (510) and two clip ends (520) formed on both sides thereof. However, according to one embodiment of the present invention, a fixing groove (530) may be formed on the inner side of the clip ends (520) as shown in FIG. 3(a). The end (330) of a fixing pin (300) may be inserted into and fixed in the fixing groove (530).

[0055] According to the embodiment, the fixing groove (530) may be formed only on one clip end (520) or on both clip ends (520). For example, when the fixing pin (300) penetrates the entire inner coupling part (120) and the outer coupling part (220) so that both ends (330) are exposed on both sides of the outer coupling part (220), the fixing groove (530) may be formed on both clip ends (520) of the clip (500). When only one end (330) of the fixing pin (300) is located on the outside of the outer coupling part (220), the fixing groove (530) may be formed only on one clip end (520) of the clip (500).

[0056] The fixing groove (530) formed in the clip end (520) allows the clip (500) and the fixing pin (300) to be more firmly joined to each other. That is, the clip end (520) not only prevents the fixing pin (300) from coming off by applying force, but also prevents the fixing pin (300) from coming off the position where the clip (500) is mounted as a part of the fixing pin (300) is inserted into the fixing groove (530).

[0057] According to one embodiment of the present invention, as shown in FIG. 3(b), the clip (500b) may further include a support projection (550). The support projection (550) may protrude in a direction intersecting the longitudinal direction, but may protrude in a direction opposite to the direction in which the clip end (520) protrudes. Assuming that the detachable cooking tool (1100) is laid on a surface such as a kitchen counter, the clip (500b) may be mounted at a position corresponding to the bottom as in FIG. 2, and the support projection (550) may protrude downward from there. Thus, when the clip (500) is mounted, the support projection (550) acts as a support to support the head (200), thereby preventing the food contact portion (210) of the head (200) from being contaminated due to contact with the counter surface.

[0058] According to one embodiment of the present invention, a fixing pin (300) may form part of a clip (500). For example, as in the clip (500c) shown in FIG. 3 (c), the fixing pin (300) may protrude inward from the inner surface of the clip end (520). When a user attaches the clip (500c) to the outer coupling part (220), the user may apply force to the clip (500c) to spread the clip end (520), align the fixing pin (300) provided on the inner side of the clip end (520) with the coupling hole (130, 230) of the outer coupling part (220) and the inner coupling part (120), and then release the clip end (520) so that the fixing pin (300) is inserted into the coupling hole (130, 230). When using the clip (500c) shown in Fig. 3 (c), the fixing pin (300) is not separated from the clip (500c), so there is no risk of the fixing pin (300) being lost.

[0059] According to one embodiment of the present invention, as shown in FIG. 3 (d), two support protrusions (550) in the clip (500d) can be connected by a connecting part (552). Thus, the support protrusions (550) and the connecting part (552) can form a kind of loop. With the clip (500d) coupled to the outer coupling part (220), the user may have the support protrusions (550) face downward to act as a support so that the food contact part (210) of the head (200) does not come into contact with the kitchen counter surface, etc., or may use the support protrusions (550) and the connecting part (552) as a loop to hang it on a hook on a wall, etc. In this case, it may be advantageous to use a structure in which one of the fixing groove (530) and the fixing pin (300) is provided on each of the two clip ends (520) so that the clip (500) cannot easily detach.

[0060] In particular, as shown in FIG. 3(b), when the support projection (550) is not connected, the clip (500b) requires a connecting portion (510) to connect the clip ends (520) on both sides. However, as shown in FIG. 3(d), when the support projection (550) is connected by the connecting portion (552), the connecting portion (552) also connects the clip ends (520), so there is an advantage that the connecting portion (510) in the middle can be omitted. Since the connecting portion (552) is provided on the opposite side of the clip ends (520) instead of the connecting portion (510) in the middle, the distance that the clip ends (520) can move due to elastic deformation can be increased. In FIG. 3(d), a contact portion (522) is provided instead of the connecting portion (510), so that the clip (500) can maintain contact with the outer coupling portion (220) over a predetermined area.

[0061] The features included in the clips (500a to 500d) illustrated in FIG. 3 may be combined if compatible, even if they are not illustrated together in one drawing. For example, a clip (500) according to one embodiment of the present invention may be implemented in a form in which a fixing pin (300) is connected to a clip end (520) and may also include a support projection (550). As another example, a clip (500) according to one embodiment of the present invention may be implemented in a form in which a fixing pin (300) is connected to one clip end (520) and a fixing groove (530) is formed on the other clip end (520).

[0062] When the user intends to attach the head (200), which is separated from the detachable cooking tool (1100) illustrated in FIGS. 1 to 3, to the handle shaft (100), the user may insert the connecting part corresponding to the inner connecting part among the first connecting part (120) of the handle shaft (100) and the second connecting part (220) of the head (200) into the insertion space (250) corresponding to the connecting part of the outer connecting part. The user may insert the inner connecting part (120) into the sleeve-shaped outer connecting part (220) so that the first connecting hole (130) is aligned with the second connecting hole (230). As described above, the cross-section of the inner coupling part (120) may have a shape corresponding to the cross-section of the insertion space (250), and if the cross-sections are not circular, the coupling hole (130) of the inner coupling part (120) may naturally be aligned with the coupling hole (230) of the outer coupling part (220) as the inner coupling part (120) is inserted.

[0063] The user can insert a fixing pin (300) into the aligned coupling holes (130, 230). As the fixing pin (300) is inserted into both the coupling hole (130) of the inner coupling part (120) and the coupling hole (230) of the outer coupling part (220), the head (200) can be coupled to the handle shaft (100).

[0064] Next, the user can mount the clip (500) to the outer coupling part (220). The user can spread the clip end (520) by applying force in the opposite direction to the direction in which the clip (500) applies elastic force to the clip end (520), and mount the clip (500) to the outer coupling part (220) by positioning the clip end (520) on both sides of the outer coupling part (220) in this state. The mounted clip (500) can apply elastic force so that the clip end (520) faces inward, and the fixing pin (300) can be fixed in a state inserted into the coupling hole (130, 230) by this elastic force applied to the clip end (520). In addition, the clip (500) can shield the area of ​​the coupling hole (130, 230) to prevent foreign matter from entering into the coupling hole (130, 230). In some embodiments of the present invention, the head (200) may be supported by the support projection (550) of the clip (500) in a manner such as contacting the surface of a kitchen counter or hanging from a hook, thereby preventing the food contact portion (210) from being contaminated.

[0065] When the user wishes to separate the head (200) attached to the detachable cooking tool (1100) from the handle shaft (100), the user may proceed with the above process in reverse order. That is, the user may apply force to the clip (500) to spread the clip end (550) and separate the clip (500) from the outer coupling part (220), and then withdraw the fixing pin (300) from the coupling hole (130, 230). Since the fixing pin (300) is no longer located within the coupling hole (130, 230), the head (200) can be separated from the handle shaft (100). The user may wash or store the separated head (200) as needed. The user may also replace the separated head (200) with another replacement head as needed.

[0066] FIG. 4 illustrates an exemplary detachable cooking tool (1200) according to a second embodiment of the present invention, and FIG. 5 illustrates an exemplary fixing pin (300) and clip (500) of the detachable cooking tool (1200).

[0067] The separable cooking tool (1200) according to the second embodiment of the present invention has many common features with the separable cooking tool (1100) according to the first embodiment described above, and below, the differences of the separable cooking tool (1200) according to the second embodiment will be described in detail. Features described in relation to the first embodiment may be applied to the second embodiment, and likewise features described in relation to the second embodiment may be applied to the first embodiment. Some reference numbers mentioned in describing the second embodiment are intended to refer to components corresponding to the components to which the corresponding reference numbers are applied in the first embodiment.

[0068] In the separable cooking tool (1200) according to the second embodiment of the present invention, the structure of the connecting part (120, 220), the fixing pin (300), and the clip (500) is slightly different from that of the separable cooking tool (1100) according to the first embodiment described above in relation to FIGS. 1 to 3.

[0069] Referring to FIGS. 4 and 5, in a separable cooking tool (1200) according to an embodiment of the present invention, a coupling hole (130, 230) can penetrate the inner coupling part (120) and the outer coupling part (220) in an up-and-down direction. Here, the up-and-down direction is based on the assumption that the separable cooking tool (1200) is laid on a surface such as a kitchen counter. A fixing pin (300) can be inserted from above into the coupling hole (130, 230) penetrating in an up-and-down direction, and a clip (500) can be coupled to the lower part of the fixing pin (300) from below the outer coupling part (220).

[0070] FIG. 5 depicts a fixing pin (300) and a clip (500) of a separable cooking tool (1200) according to a second embodiment of the present invention, wherein in FIG. 5 (a), the clip (500) is separated from the fixing pin (300), and in FIG. 5 (b), the clip (500) is fastened to the fixing pin (300).

[0071] Referring to FIG. 5, in one embodiment of the present invention, the pin member (310) of the fixing pin (300) may have a cross-section that is not circular but extends longer in one direction. The pin member (310) may have, for example, a rectangular cross-section. For convenience of explanation, the direction in which the cross-section of the pin member (310) has a longer length is referred to as the "long side direction," and the direction in which the cross-section of the pin member (310) has a shorter length is referred to as the "short side direction," which is orthogonal to this direction within the same plane. The use of the terms "long side" and "short side" is intended to aid explanation and understanding, and the cross-section of the pin member (310) is not limited to a rectangular shape.

[0072] The pin member (310) is formed with a length greater than the diameter of the outer coupling part (220), so that the lower end of the pin member (310) passes through the coupling hole (230) of the outer coupling part (220) and is located on the outside of the outer coupling part (220).

[0073] A stopper (340) may be formed at one end of the fixing pin (300). The stopper (340) may be formed so as not to pass through the coupling hole (230) of the outer coupling part (220). For example, the stopper (340) may be formed with a dimension larger than the coupling hole (230) of the outer coupling part (220) in at least one direction.

[0074] A locking groove (350) may be formed at the other end of the fixing pin (300). The locking groove (350) may be formed at one or both ends based on the long side direction of the pin member (310), as depicted in FIG. 5 (a). Although the pin member (310) generally has a cross-section that extends longer along the long side direction, the length in the long side direction may correspond to the length in the short side direction in the portion where the locking groove (350) is formed.

[0075] In one embodiment of the present invention, the clip (500) may be coupled to the locking groove (350) of the fixing pin (300) to serve to fix the fixing pin (300). Referring to FIG. 5, in a separable cooking tool (1200) according to one embodiment of the present invention, the clip (500) may be implemented in a form in which an insertion hole (545) is formed in its main body (540). The insertion hole (545) may be formed in a shape corresponding to the cross-section of the pin member (310) so that the pin member (310) of the fixing pin (300) can pass through. While the main body (540) of the clip (500) itself may have various shapes, as long as the insertion hole (545) is extended in one direction corresponding to the pin member (310), there is an advantage that it becomes easier for the user to operate it if the main body (540) is also extended in the same direction.

[0076] A support projection (550) may be provided at the lower part of the main body (540). The length of the support projection (550) protruding downward from the main body (540) may be designed to be greater than the distance from the end of the pin member (310) to the locking groove (350) in the fixing pin (300).

[0077] When the user intends to attach the head (200), which is separated from the detachable cooking tool (1200) illustrated in FIGS. 4 and 5, to the handle shaft (100), the user may insert the connecting part corresponding to the inner connecting part among the first connecting part (120) of the handle shaft (100) and the second connecting part (220) of the head (200) into the insertion space (250) corresponding to the connecting part of the outer connecting part. The user may insert the inner connecting part (120) into the sleeve-shaped outer connecting part (220) so that the first connecting hole (130) is aligned with the second connecting hole (230).

[0078] The user can insert the pin member (310) of the fixing pin (300) into the aligned coupling holes (130, 230). Based on the state where the cooking tool (1200) is lying down, the fixing pin (300) can be inserted into the coupling holes (130, 230) from above. When the pin member (310) is inserted into the coupling hole (130) of the inner coupling part (120) and the coupling hole (230) of the outer coupling part (220), the stopper (340) formed at one end of the fixing pin (300) cannot pass through the coupling hole (230) of the outer coupling part (220), so it can be in close contact with the outer coupling part (220), and the lower part of the pin member (310) can be exposed outside the coupling hole (230) located below among the coupling holes (230) of the outer coupling part (220). A locking groove (350) is formed in the portion of the pin member (310) that is exposed outside the coupling hole (230).

[0079] Next, the user can mount the clip (500) in the locking groove (350) of the fixing pin (300). The user can position the clip (500) so that the exposed lower part of the pin member (310) passes through the insertion hole (545) of the clip (500). Since the insertion hole (545) of the clip (500) is formed in a shape corresponding to the cross-section of the pin member (310), the clip (500) must be mounted in a predetermined direction as shown in (a) of FIG. 5.

[0080] When the clip (500) is inserted into the pin member (310) and reaches the locking groove (350), the clip (500) can be closely attached to the outer surface of the outer coupling part (220). Subsequently, the user can rotate the clip (500) as shown in (b) of FIG. 5. Since the insertion hole (545) of the clip (500) is basically formed in a shape corresponding to the cross-section of the pin member (310), the clip (500) cannot be rotated in other parts, but at that position, the locking groove (350) is formed in the pin member (310), so the clip (500) can be rotated. When the clip (500) is rotated in this way, the fixing pin (300) can be fixed by the stopper (340) on one side and by the clip (500) on the other side. The lower end of the pin member (310) of the fixing pin (300) can pass through the insertion hole (545) and protrude below the main body (540) of the clip (500), but the lower end of the clip (500) has a support projection (550) so as not to cause inconvenience during use.

[0081] When the user wishes to separate the head (200) attached to the detachable cooking tool (1200) from the handle shaft (100), the user may proceed with the above process in reverse order. That is, the user may rotate the clip (500) so that the insertion hole (545) aligns with the cross-section of the pin member (310), and separate the clip (500) so that the lower part of the pin member (310) is withdrawn from the insertion hole (545). The user may then withdraw the fixing pin (300) from the coupling hole (130, 230). Since the fixing pin (300) is no longer located within the coupling hole (130, 230), the head (200) can be separated from the handle shaft (100). The user may wash or store the separated head (200) as needed. The user may also replace the separated head (200) with another replacement head as needed.

[0082] FIG. 6 is an exploded perspective view illustrating an exemplary separable cooking tool (1300) according to a third embodiment of the present invention.

[0083] The separable cooking tool (1300) according to the third embodiment of the present invention has many commonalities with the separable cooking tools (1100, 1200) according to the first and second embodiments described above, and the following description will focus on the differences of the separable cooking tool (1300) according to the third embodiment. Features described in relation to the first or second embodiment may be applied to the third embodiment, and likewise features described in relation to the third embodiment may be applied to the first and second embodiments. Some reference numbers mentioned in describing the third embodiment are intended to refer to components corresponding to the components to which the corresponding reference numbers are applied in the first and / or second embodiments.

[0084] In the detachable cooking tool (1300) according to the third embodiment of the present invention, the structure of the connecting part (120, 220), the fixing pin (300), and the clip (500) is slightly different from that of the detachable cooking tool (1100, 1200) according to the first and second embodiments described above.

[0085] Referring to FIG. 6, in a separable cooking tool (1300) according to one embodiment of the present invention, the coupling hole (130) of the inner coupling part (120) is formed in the shape of a groove formed on the outer surface of the inner coupling part (120). In a separable cooking tool (1300) according to a third embodiment of the present invention, the fixing pin (300) is formed as part of the clip (500), and the fixing pin (300) can be inserted in a tangential direction rather than a radial direction between the inner coupling part (120) and the outer coupling part (220).

[0086] In this embodiment, the fixing pin (300) may form part of the clip (500). As in the example illustrated in FIG. 6, the clip (500) may include two fixing pins (300) and a connecting part (510) connecting them to each other. Similar to the above-described embodiment, the clip (500) may apply an elastic force to the fixing pins (300) in a direction toward each other. However, in this embodiment, the clip (500) may be configured not to apply an elastic force.

[0087] The fixing pin (300) can be inserted in a tangential direction rather than a radial direction of the inner coupling part (120) and the outer coupling part (220). The thickness of the inner coupling part (120), the outer coupling part (220), and the fixing pin (300) can be formed with a sufficient thickness so that the fixing pin (300) can be inserted into both the coupling holes (130, 230) of the inner coupling part (120) and the outer coupling part (220).

[0088] When the user intends to attach the head (200), which is separated from the detachable cooking tool (1300) illustrated in FIG. 6, to the handle shaft (100), the user may insert the connecting part corresponding to the inner connecting part among the first connecting part (120) of the handle shaft (100) and the second connecting part (220) of the head (200) into the insertion space (250) corresponding to the connecting part of the outer connecting part. The user may place the inner connecting part (120) within the sleeve-shaped outer connecting part (220) so that the first connecting hole (130) is aligned with the second connecting hole (230).

[0089] The user can mount the clip (500) on the outer coupling part (220) so that the fixing pin (300) is inserted into the aligned coupling hole (130, 230). As the clip (500) approaches the outer coupling part (220), the fixing pin (300), which forms part of the clip (500), can enter in a tangential direction of the outer coupling part (220) and be inserted into the coupling hole (130, 230). When the clip (500) applies elastic force to the fixing pin (300), the user can apply force to spread the fixing pin (300).

[0090] When the clip (500) is fully mounted, each fixing pin (300) can be inserted into the coupling hole (130, 230), and the connecting portion (510) between the fixing pins (300) can be in close contact with the outer coupling portion (220). At this time, the outer surface of the fixing pin (300) can be continuously connected to the outer surface of the outer coupling portion (220). The connecting portion (510) may be configured so that its outer surface is continuously connected to the outer surface of the outer coupling portion (220), or it may protrude further than the outer coupling portion (220) to serve the same function as the aforementioned support projection (550).

[0091] When the user wishes to separate the head (200) attached to the detachable cooking tool (1300) from the handle shaft (100), the user may proceed with the above process in reverse order. The user may pull the clip (500) to separate it from the outer coupling part (220), and as a result, the fixing pins (300) on both sides may naturally separate from the coupling holes (130, 230). Since the fixing pins (300) are no longer located within the coupling holes (130, 230), the head (200) may be separated from the handle shaft (100). The user may wash or store the separated head (200) as needed. The user may also replace the separated head (200) with another replacement head as needed.

[0092] FIG. 7 illustrates an exemplary detachable cooking tool (1400) according to a fourth embodiment of the present invention, and FIG. 8 illustrates an exemplary clip (500) of the detachable cooking tool (1400) according to a fourth embodiment of the present invention.

[0093] The separable cooking utensil (1400) according to the fourth embodiment of the present invention has many commonalities with the separable cooking utensils (1100 to 1300) according to the first to third embodiments described above, and the following description will focus on the differences of the separable cooking utensil (1400) according to the fourth embodiment. Features described in relation to the first, second, or third embodiments may be applied to the fourth embodiment, and likewise features described in relation to the fourth embodiment may be applied to the first, second, and third embodiments. Some reference numbers mentioned in describing the fourth embodiment are intended to refer to components corresponding to the components to which the corresponding reference numbers are applied in the previously presented embodiments.

[0094] The detachable cooking tool (1400) according to the fourth embodiment of the present invention has a structure in which a clip (500) is coupled to an outer coupling part (120) so that it can move along the longitudinal direction. For reference, in the example illustrated in FIG. 7, the first coupling part (120) provided on the handle shaft (100) corresponds to the outer coupling part and is implemented in the form of a sleeve having an insertion space (150) on the inside, and the second coupling part (220) provided on the head (2000) corresponds to the inner coupling part and is inserted into the insertion space (150). As described above, it will be obvious to a person of ordinary knowledge that either the first coupling part (120) of the handle shaft (100) or the second coupling part (220) of the head (200) can act as the outer coupling part and the other can act as the inner coupling part.

[0095] As illustrated in FIG. 7, the clip (500) may be configured to be movable along the longitudinal direction by being mounted on the outer circumference of the outer coupling portion (120). The clip (500) may have an annular cross-section that forms a completely closed curve, but may also be formed in an elastic, bent shape ("C" shape) as in the first embodiment. If the clip (500) is formed in a "C" shape, a mounting groove similar to the mounting groove (240) illustrated in FIG. 2 may be formed in the outer coupling portion (120).

[0096] FIG. 8 is a cross-sectional view exemplarily showing a clip (500) of a separable cooking tool (1400) according to a fourth embodiment of the present invention, in which the inner surface of the clip (500) is also depicted.

[0097] When the clip (500) is formed in an annular shape, the main body (560) of the clip (500) may have an inner diameter corresponding to the outer diameter of the outer coupling part (120). Although not shown in the drawing, a configuration for guiding the movement of the clip (500) relative to the outer coupling part (120) may be provided on the outer surface of the outer coupling part (120) and on the inner surface of the clip (500).

[0098] For example, a guide rail extending along the longitudinal direction may be formed on either the outer surface of the outer coupling part (120) or the inner surface of the clip body (560), and a guide groove extending along the longitudinal direction may be formed on the other. In FIGS. 7 and 8, a guide rail (190) is formed on the outer surface of the outer coupling part (120), and a guide groove (590) is formed on the inner surface of the clip body (560).

[0099] When the clip (500) is coupled to the outer coupling part (120), the guide rail can be inserted into the guide groove, and the clip (500) can only move along the guide rail or the guide groove. This structure can keep the clip (500) aligned in a predetermined orientation and can also limit the range of movement of the clip (500) on the outer coupling part (120).

[0100] According to one embodiment of the present invention, a fixing groove (570) may be formed on the inner surface of the clip body (560). Unlike the guide groove (590) described above, into which a separate guide rail (190) is inserted, the end (330) of the fixing pin (300) may be inserted into the fixing groove (570). That is, the fixing pin (300) may be configured such that its end (330) protrudes outside the coupling hole (130) of the outer coupling part (120) while the fixing pin (300) is fully inserted into the coupling hole (130, 230), and the end (330) of the fixing pin (300) exposed outside the coupling hole (130) may be inserted into the fixing groove (570) formed on the inner side of the clip (500). The fixing groove (570) may perform a similar function to the fixing groove (530) described above in relation to FIG. 3.

[0101] In order for the end (330) of the fixing pin (300) to be inserted into the fixing groove (570), the fixing groove (570) may have a width corresponding to the thickness of the end (330) of the fixing pin (300). Additionally, the fixing groove (570) may extend from a predetermined position on the inner surface of the clip body (560) to the lower or upper part of the clip body (560) and open to the lower or upper part. In the case of the structure shown in FIGS. 7 and 8, the first coupling part (120) provided on the handle shaft (100) corresponds to the outer coupling part, and since the clip (500) is mounted by moving downward from the outside of the outer coupling part (120), the fixing groove (570) extends downward from a predetermined position of the clip body (560) as shown in FIG. 8 and opens to the lower part of the clip body (560). In some embodiments of the present invention, a second coupling portion (220) provided on the head (200) corresponds to an outer coupling portion, and the clip (500) may be mounted by moving upward from the outer side of the outer coupling portion (220). In this case, the fixing groove (570) may extend upward from a predetermined position of the clip body (560) and open to the upper part of the clip body (560).

[0102] Meanwhile, according to one embodiment of the present invention, the clip (500) may further include a locking projection (580) formed within the fixing groove (570). The locking projection (580) may protrude inward from within the fixing groove (570). The length of the protrusion of the locking projection (580) may be determined such that the innermost part of the locking projection (580) does not protrude further inward than the inner surface of the clip body (560). The position of the locking projection (580) may correspond to a position located at a distance from the end of the fixing groove (570) that corresponds to the diameter of the end (330) of the fixing pin (300). The fixing groove (570) and the locking projection (580) may serve to prevent the clip (500) from arbitrarily deviating from the locking position in which the fixing pin (300) is fixed.

[0103] When the user intends to attach the head (200), which is separated from the detachable cooking tool (1400) illustrated in FIGS. 7 and 8, to the handle shaft (100), the user may insert the connecting part corresponding to the inner connecting part among the first connecting part (120) of the handle shaft (100) and the second connecting part (220) of the head (200) into the insertion space (150) of the connecting part corresponding to the outer connecting part. The user may insert the inner connecting part (220) into the sleeve-shaped outer connecting part (120) so that the first connecting hole (130) is aligned with the second connecting hole (230). As described above, the cross-section of the inner coupling part (220) may have a shape corresponding to the cross-section of the insertion space (150), and if the cross-sections are not circular, the coupling hole (230) of the inner coupling part (220) may naturally be aligned with the coupling hole (130) of the outer coupling part (120) as the inner coupling part (220) is inserted.

[0104] The user can insert a fixing pin (300) into the aligned coupling holes (130, 230). As the fixing pin (300) is inserted into both the coupling hole (230) of the inner coupling part (220) and the coupling hole (130) of the outer coupling part (120), the head (200) can be coupled to the handle shaft (100).

[0105] Next, the user can mount the clip (500), and to do so, the clip (500) can be moved toward the fixing pin (300) on the outer coupling part (120). The user can move the clip (500) so that the end (330) of the fixing pin (300) exposed outside the coupling hole (130) is inserted into the fixing groove (570). When the outer coupling part (120) and the clip (500) are provided with a guide rail and a guide groove, the clip (500) can be maintained in an aligned state with respect to the end (330) of the fixing pin (300), and the user can mount the clip (500) in a locked position simply by moving the clip (500).

[0106] As the clip (500) moves to a locking position where the fixing pin (300) is located, the end (330) of the fixing pin (300) can be inserted into the fixing groove (570) inside the clip (500). That is, the end (330) of the fixing pin (300) can enter the fixing groove (570) through the open lower (or upper) portion of the fixing groove (570). If the clip (500) includes a locking projection (580), the end (330) of the fixing pin (300) comes into contact with the locking projection (580) and receives resistance applied by the locking projection (580). If the user applies a greater force, the clip (500) undergoes slight elastic deformation, and the end (330) of the fixing pin (300) can pass over the locking projection (580). In this state, the end (330) of the fixing pin (300) is positioned between the end of the fixing groove (570) and the locking projection (580), so the movement of the clip (500) is suppressed in all directions, and consequently, the clip (500) can maintain a firmly fixed state in the corresponding locking position.

[0107] When the user wishes to separate the head (200) attached to the detachable cooking tool (1400) from the handle shaft (100), the user may proceed with the above process in reverse order. That is, the user may apply force to the clip (500) so that the end (330) of the fixing pin (300) passes over the locking projection (580) again. When the clip (500) moves in the longitudinal direction and moves out of the locking position and no longer contacts the fixing pin (300), the user may withdraw the fixing pin (300) from the coupling hole (130, 230). Since the fixing pin (300) is no longer located within the coupling hole (130, 230), the head (200) can be separated from the handle shaft (100). The user may wash or store the separated head (200) as needed. The user may also replace the separated head (200) with another replacement head as needed.

[0108] In the separable cooking tools (1100 to 1400) according to the first to fourth embodiments of the present invention presented above, a fixing pin (300) is inserted into the coupling holes (130, 230) of the inner coupling part (120) and the outer coupling part (220) to firmly connect the handle shaft (100) and the head (200), and a clip (500) can prevent the fixing pin (300) from moving out of its position. This structure allows the head (200) to remain firmly connected to the handle shaft (100) when connection of the head (200) is required, while allowing the user to easily detach the head (200) when separation is required for cleaning, thereby increasing user convenience.

[0109] In addition, in the separable cooking tools (1100 to 1400) according to the first to fourth embodiments of the present invention, the fixing pin (300) and / or clip (500) can prevent foreign substances from entering the coupling hole (230) of the outer coupling part (220) into which the fixing pin (300) is inserted. This can prevent the phenomenon in which food or other substances cause bacterial growth in the coupling hole (230), and can prevent the coupling between the inner and outer coupling parts (120, 220) and the fixing pin (300) from becoming loose or the contact area from wearing out due to foreign substances.

[0110] In addition, in the detachable cooking tools (1100 to 1400) according to the first to fourth embodiments of the present invention, the head (200) may include a plurality of replacement heads (200a, 200b), and the user may select a replacement head (200a, 200b) having a food contact portion (210) of the desired shape and attach it to the handle shaft (100). This provides the advantage of being able to use various types of cooking tools while significantly reducing the space required to store these tools.

[0111] Although the present invention has been described above with reference to one embodiment, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as described in the following claims.
