Summary of the Invention

Problems to be Solved by the Invention

[0004] In the lid opening and closing assist device disclosed in Patent Document 1, it has a configuration in which a rod-shaped handle is attached to a rectangular plate material provided with a recessed portion, and the rod-shaped handle is grasped by hand, and the lid of the pot is opened by hooking the recessed portion on the knob of the lid and lifting it, and the lid is closed by covering the lid on the pot with the knob hooked on the recessed portion. However, in the operation of opening and closing the lid using the lid opening and closing assist device having such a configuration, the user has to perform an operation different from the operation when opening and closing the lid by holding the knob by hand without using the lid opening and closing assist device, and thus the user feels a sense of discomfort with the operation feeling.

[0005] This invention has been made in view of the above circumstances, and aims to provide a lid opening and closing assist device that enables users to open and close the lid of a cooking pot without feeling any discomfort. [Means for solving the problem]

[0006] The lid opening and closing assist device according to Invention 1 is A lid opening and closing aid for a cooking pot, wherein the knob is located approximately in the center of the lid and is formed in a T-shape such that, in a side view, the head of the knob is wider horizontally than the base of the knob, and the knob is projected upward from the top surface of the lid, and the aid is detachably attached to the knob by moving it in a horizontal direction, The aforementioned lid opening and closing assist device is, The upper part of the lid opening / closing assist device comprises a gripping portion for gripping the lid opening / closing assist device, It comprises a knob storage section located below the gripping section, in which the knob is housed inside the lid opening / closing assisting device, The knob storage section is, A side opening is provided on one surface of the outer peripheral side wall of the lid opening / closing assisting device that is substantially perpendicular to the direction mentioned above, and which extends to the lower end of the outer peripheral side wall, A lower opening is provided on the lower surface of the bottom wall of the lid opening / closing aid, and is in communication with the side opening, It has a space recessed from the side opening toward the central part of the lid opening / closing aid, The aforementioned space is A knob storage space includes a head storage space in which the knob head is stored and a base storage space in which the knob base is stored in the storage position of the knob, The knob passage space includes a head passage space through which the knob head can pass and a base passage space through which the knob base can pass, located between the side opening and the knob storage space. In the first viewing direction, the horizontal width of the head storage space is at least greater than the horizontal width of the base storage space.

[0007] Here, the horizontal direction can be, for example, the forward direction with the front of the lid opening / closing aid facing forward, and the plane substantially perpendicular to the direction can be the front of the lid opening / closing aid, and the view in the direction can be the front view of the lid opening / closing aid.

[0008] According to the above configuration, when the lid opening / closing assist device of the present invention is attached to the knob of a cooking pot lid by storing the knob in the knob storage space through the side opening, the device can cover the knob at approximately the same position, and the gripping portion of the lid opening / closing assist device is positioned above the knob. Therefore, the lid can be opened and closed by holding the gripping portion of the lid opening / closing assist device with the same force as when opening and closing the lid by holding the knob with one's hand. Consequently, with the lid opening / closing assist device of the present invention, there is little difference in the feel of opening and closing the lid compared to when the lid opening / closing assist device is not used, thus eliminating any discomfort the user may feel when opening and closing the lid.

[0009] Furthermore, when the lid opening / closing aid is attached to the knob on the lid, the gripping portion that makes up the upper part of the lid opening / closing aid is located above the knob, so the hand holding the gripping portion is less likely to come into contact with the lid. The knob storage space of the lid opening / closing aid has a horizontal width in the head storage space that is wider than the horizontal width in the base storage space, so the T-shaped knob can be held firmly, allowing the lid to be opened and closed stably.

[0010] The lid opening and closing assist device according to Invention 2 is, In the lid opening and closing assist device of the above invention 1, In the aforementioned first viewing direction, the horizontal width of the head passage space is set to be approximately the same as or larger than the horizontal width of the head storage space. In the aforementioned first viewing direction, the horizontal width of the base passage space can be set to be approximately the same as or larger than the horizontal width of the base storage space.

[0011] According to the above configuration, the lid opening / closing aid can be easily attached to the knob on the lid of the cooking pot from the side (horizontal direction), thereby improving the usability of the lid opening / closing aid.

[0012] The lid opening and closing assist device according to Invention 3 is In the lid opening and closing assist device of invention 1 or 2, The side walls of the base passage space and / or the side walls of the head passage space may be provided with protruding protrusions.

[0013] According to the above configuration, when the knob of the lid is stored in the knob storage space of the lid opening / closing assist tool and the lid is opened or closed, the protrusion prevents the knob of the lid opening / closing assist tool from coming loose, thereby improving the usability of the lid opening / closing assist tool.

[0014] The lid opening and closing assist device according to Invention 4 is In any one of the above inventions 1 to 3, a lid opening and closing assist device, The gripping portion may be configured to have at least a constricted portion having a horizontal width that is smaller than the horizontal width of the upper part of the gripping portion when viewed in a direction facing the one surface.

[0015] According to the above configuration, the constricted portion allows the user to firmly grip the lid opening and closing assist tool, enabling stable opening and closing of the lid and improving the usability of the lid opening and closing assist tool. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in Figs. 1(a)(b) and Fig. 2, the lid opening / closing assist tool 1 of the embodiment is a tool used to detachably attach this lid opening / closing assist tool 1 to the knob 3 of the lid 22 of the cooking pot 2 by moving it in one direction in the horizontal direction and to open and close the lid 22. By using this lid opening / closing assist tool 1, the lid 22 can be easily opened and closed without directly holding the knob 3 that has become hot during cooking by hand. In the present embodiment, the one direction in the horizontal direction is the forward direction with the front of the lid opening / closing assist tool 1 facing forward.

[0018] The cooking pot 2 comprises a pot body 21 formed in a bottomed cylindrical shape with an open top for holding food to be cooked, and a disc-shaped lid 22 that covers the open top of the pot body 21. The pot body 21 has handles 4 that protrude outward from the left and right positions on the upper part of the side surface. The lid 22 is located in the center and has a knob 3 that protrudes upward from the top surface of the lid 22. The knob 3 is composed of an upper knob head 31 and a lower knob base 32, and is formed in a roughly T-shape, with the knob head 31 being wider horizontally than the knob base 32 when viewed from the side (see Figure 2). In this embodiment of the knob 3, the knob head 31 has a disc shape, and the knob base 32 has a cylindrical shape with a reduced outer shape in the middle, as if the tips of two cones were joined together. Furthermore, the shape of the cooking pot 2 is not limited to a circle; any shape such as an oval, square, or other polygon can be selected. The shape of the knob 3 is also not limited to a circle; any shape such as a mushroom-shaped knob head 31 or a cylindrical knob base 32 can be selected. The overall shape of the knob 3 is also not limited to a circle; any shape such as an oval, square, or other polygon can be selected. In addition, the material of the pot body 21 and lid 22 can be metal, pottery, ceramic, etc., and the knob 3 can be metal, resin, ceramic, wood, etc.

[0019] As shown in Figures 3 and 4(a) to 4(e), the lid opening / closing aid 1 of the embodiment has an overall shape that is roughly cylindrical. The upper part of this roughly cylindrical shape constitutes a gripping part 5 for gripping the lid opening / closing aid 1 by hand, and the lower part located below the gripping part 5 constitutes a knob storage part 6 for storing the knob 3 of the lid 22 inside the lid opening / closing aid 1. The raw material for manufacturing the lid opening / closing aid 1 of the embodiment is phenolic resin, but other resins may be used, as well as metal, ceramic, wood, etc. It is preferable to use a raw material for the lid opening / closing aid 1 that has lower thermal conductivity than the knob 3. In this case, the lid opening / closing aid 1 will not become hot when attached to the hot knob 3. Furthermore, the shape of the lid opening / closing aid 1 is not limited to a roughly cylindrical shape, but may also be an elliptical prism, a polygonal prism such as a rectangular prism, etc. Furthermore, the lid opening / closing assist tool 1 may have different dimensions, such as width and height, and different shapes, between the upper part that constitutes the gripping part 5 and the lower part that constitutes the knob storage part 6.

[0020] The gripping portion 5 has a flange portion 51 formed on the upper part of the gripping portion 5 and a constricted portion 52 below the flange portion 51. The flange portion 51 is formed in a disc shape, and the constricted portion 52 is formed in a cylindrical shape. The diameter of the cylindrical constricted portion 52 is set to a smaller dimension than the diameter of the disc shape of the flange portion 51. The diameter of the constricted portion 52 and the diameter of the flange portion 51 are their respective widths in the horizontal direction.

[0021] The knob storage section 6 has a side opening 61 provided on the front surface (Figure 4(a)) of the outer peripheral side wall of the lid opening / closing assist device 1, a bottom opening 62 provided on the bottom surface (Figure 4(e)) of the bottom wall of the lid opening / closing assist device 1, and a space 7 recessed from the side opening 61 toward the central part of the lid opening / closing assist device 1. The front surface of the outer peripheral side wall of the lid opening / closing assist device 1 is a surface that is substantially perpendicular to one of the horizontal directions of the lid opening / closing assist device 1.

[0022] The side opening 61 extends to the lower end of the outer peripheral side wall of the lid opening / closing aid 1 and has a roughly T-shape that mimics the projected shape of the knob 3 in side view, and is set to a size larger than the knob 3. The side opening 61 serves as the entrance and exit for the knob 3 when attaching and detaching the lid opening / closing aid 1 to the knob 3. The bottom opening 62 has a roughly U-shape that opens on the front side of the outer peripheral side wall and communicates with the side opening 61, and serves as an opening to ensure the passage of the knob base 32 when attaching and detaching the lid opening / closing aid 1 to the knob 3, and is set to a size larger than the thickness of the knob base 32.

[0023] Referring also to Figures 5 and 6, the space 7 has a knob storage space 71 which comprises a head storage space 71A in which the knob head 31 is stored and a base storage space 71B in which the knob base 32 is stored, at the storage position of the knob 3 which is approximately in the center of the lid opening / closing aid 1, and a knob passage space 72 which comprises a head passage space 72A through which the knob head 31 can pass and a base passage space 72B through which the knob base 32 can pass, in the range from the side opening 61 to the knob storage space 71.

[0024] As shown in Figure 6, a side wall portion 60 is provided on the outer periphery of the head storage space 71A, forming a semicircular side wall that encloses a part of the head storage space 71A. On the outer side of the base passage space 72B, a pair of left and right arm portions 8a and 8b are provided, forming side walls on the left and right sides of the base passage space 72B in the horizontal direction. The portions behind this pair of arm portions 8a and 8b are connected in an arc shape that encloses the base storage space 71B. The outer periphery of the bottom opening 62 on the lower surface of the bottom wall of the lid opening / closing aid 1 is an inclined portion 82 (see Figures 4(a) and 4(e)) that slopes upward toward the bottom opening 62, following the conical shape of the knob base portion 32 of the knob 3. In addition, the bottom ends of the pair of arm portions 8a and 8b have notches 82A (see Figures 4(b) and 4(e)) that slope upward toward the tips.

[0025] The dimensions of the knob storage space 71 and the knob passage space 72 are set to be larger than the dimensions of the knob 3. Since the knob passage space 72 is a space formed continuously from the side opening 61, the shape and dimensions of the side opening 61 are set depending on the shape and dimensions of the knob passage space 72.

[0026] The head storage space 71A is a cylindrical space slightly larger than the knob head 31 so that the knob head 31 can be stored inside. The base storage space 71B is a cylindrical space slightly larger than the knob base 32 so that the knob base 32 can be stored inside. In a front view of the lid opening / closing aid 1, the horizontal width of the head storage space 71A is larger than the horizontal width of the base storage space 71B. Therefore, when the knob 3 is attached to the knob storage space 71 and the lid opening / closing aid 1 is lifted, the knob 3 will not fall out from the bottom wall of the lid opening / closing aid 1. In this embodiment, in a front view of the lid opening / closing aid 1, the horizontal width of the head passage space 72A is larger than the horizontal width of the base passage space 72B, however, the horizontal width of the base passage space 72B may be formed to be approximately the same size as the horizontal width of the head passage space 72A.

[0027] The head passage space 72A is a roughly arc-shaped space extending from the lateral opening portion of the side opening 61 to the head storage space 71A, as seen from the front of the lid opening / closing assist device 1, with the width and height of the lateral opening portion of the side opening 61. The base passage space 72B is a roughly rectangular space extending from the vertical opening portion to the base storage space 71B, as seen from the front of the lid opening / closing assist device 1, with the width and height of the vertical opening portion of the side opening 61.

[0028] In a front view of the lid opening / closing assist device 1, the horizontal width of the head passage space 72A and the horizontal width of the head storage space 71A are set to be larger than the width (diameter) of the knob head 31 of the target knob 3. In this embodiment, the horizontal width of the head passage space 72A is formed to be approximately the same as the horizontal width of the head storage space 71A, but the horizontal width of the head passage space 72A may be formed to be larger than the horizontal width of the head storage space 71A.

[0029] In a front view of the lid opening / closing assist device 1, the horizontal width of the base passage space 72B and the horizontal width of the base storage space 71B are set to be larger than the width (diameter) of the knob base 32 of the knob 3 in question. In this embodiment, the horizontal width of the base passage space 72B is formed to be approximately the same as the horizontal width of the base storage space 71B, but the horizontal width of the base passage space 72B may be formed to be larger than the horizontal width of the base storage space 71B.

[0030] The left and right side walls of the base passage space 72B are provided with a pair of protrusions 81a and 81b (see Figure 4(a)) projecting toward the opposing side wall. The pair of protrusions 81a and 81b are located near the base storage space 71B, but may be provided at any position within the range of the side walls of the base passage space 72B. The distance between the pair of protrusions 81a and 81b is set to be slightly larger than the diameter of the knob base 32. If the head passage space 72A has side walls on both sides, the protrusions 81a and 81b may be provided on these left and right side walls. In this case, the protrusions 81a and 81b may be provided on both or either the side walls of the base passage space 72B and the side walls of the head passage space 72A. The protrusion 81 may also be provided on only one of the left and right side walls.

[0031] In addition, on the top surface of the lid opening / closing assist tool 1 (the same as the upper surface of the upper part of the gripping part 5), there is a mark m (see FIGS. 3 and 4(d)) indicating the position on the front side of the lid opening / closing assist tool 1 provided with the side opening 61. In the present embodiment, as this mark m, characters are engraved, and the surface of the outer peripheral side wall corresponding to the front side in the top view of the lid opening / closing assist tool 1 in a direction where the characters can be read normally becomes the front of the lid opening / closing assist tool 1 provided with the side opening 61. Therefore, the user holds the gripping part 5 of the lid opening / closing assist tool 1 with the hand in a direction where the characters serving as the mark m can be read normally, and the orientation of the lid opening / closing assist tool 1 held in the hand naturally becomes an orientation where the front of the lid opening / closing assist tool 1 provided with the side opening 61 is located on the front side of the hand. In this state, if the lid opening / closing assist tool 1 is moved toward the knob 3 of the lid 22, the knob 3 can be easily attached to the knob storage space 71 through the side opening 61. Note that the mark m can be various characters such as "front", and in addition to characters, the mark m may also be a symbol such as an arrow, a figure, a pattern, a design, or the like.

[0032] Next, the usage method of the lid opening / closing assist tool 1 will be described. Referring to FIGS. 1(a)(b) and FIG. 2, when opening the lid 22 of the cooking pot 2, the user holds the gripping part 5 of the lid opening / closing assist tool 1 with the hand and moves the lid opening / closing assist tool 1 in a substantially horizontal direction toward the knob 3 of the lid 22. With respect to the knob 3, the lid opening / closing assist tool 1 is inserted from its side opening 61, the knob 3 is placed in the knob storage space 71, and the lid opening / closing assist tool 1 is attached to the knob 3. In this state, by moving the lid opening / closing assist tool 1 upward, the lid 22 can be lifted to open the lid 22 from the cooking pot 2 (see FIG. 5). When closing the lid 22, starting from the state where the lid opening / closing assist tool 1 attached to the knob 3 is held in the hand, the lid 22 of the cooking pot 2 can be closed by moving it downward so as to cover the upper opening part of the pot body 21. After closing the lid 22, the lid opening / closing assist tool 1 can be easily removed from the knob 3 by moving the lid opening / closing assist tool 1 in the horizontal direction (the opposite direction to the attachment time).

[0033] As described above, with the lid opening / closing assist device 1 of this embodiment, when the knob 3 of the lid 22 of the cooking pot 2 is placed in the knob storage space 71 through the side opening 61 and attached to the knob 3, the knob 3 can be covered at approximately the same position as the knob 3, and the gripping part 5 of the lid opening / closing assist device 1 is positioned above the knob 3 (see Figure 1(b)). Therefore, just as when opening and closing the lid 22 by holding the knob 3 with one's hand, the lid 22 can be opened and closed by holding the gripping part 5 of the lid opening / closing assist device 1 with one's hand. Accordingly, with the lid opening / closing assist device 1 of this embodiment, there is little difference in the feel of opening and closing the lid 22 compared to when opening and closing the lid 22 without using the lid opening / closing assist device 1, thus eliminating any discomfort the user may feel when opening and closing the lid 22.

[0034] Furthermore, for example, when opening and closing the lid 22 of the cooking pot 2 to check the progress of cooking, using an oven mitt would be cumbersome and time-consuming as the mitt had to be put on and taken off each time the lid 22 was opened or closed. However, with the lid opening and closing assist tool 1 of this embodiment, the user can simply hold the lid opening and closing assist tool 1 in their hand and attach it to the knob 3 of the lid 22, and operate it in the same way as when opening and closing the lid 22 by holding the knob 3 in their hand. This allows for easy and convenient opening and closing of the lid 22 without any confusion about the operation method. Moreover, even if a user sees this lid opening and closing assist tool 1 for the first time, they can intuitively understand how to use it and use it to open and close the lid 22.

[0035] When the lid opening / closing assist device 1 is attached to the knob 3 of the lid 22, the gripping portion 5 that constitutes the upper part of the lid opening / closing assist device 1 is located above the knob 3, which has the advantageous effect of making it difficult for the hand holding the gripping portion 5 to move away from the lid 22 and come into contact with the lid 22. In addition, the knob storage space 71 of the lid opening / closing assist device 1 has a horizontal width in the head storage space 71A that is wider than the horizontal width in the base storage space 71B, so that the roughly T-shaped knob 3 can be firmly held, and the lid 22 can be opened and closed stably.

[0036] In the knob storage section 6, the horizontal width of the head passage space 72A is formed to be approximately the same as the horizontal width of the head storage space 71A, and the horizontal width of the base passage space 72B is formed to be approximately the same as the horizontal width of the base storage space 71B. This makes it easier to attach the lid opening / closing aid 1 to the knob 3 of the lid 22 of the cooking pot 2 from the side (horizontal direction), thereby improving the usability of the lid opening / closing aid 1. If the horizontal width of the head passage space 72A is formed to be larger than the horizontal width of the head storage space 71A, and the horizontal width of the base passage space 72B is formed to be larger than the horizontal width of the base storage space 71B, it becomes even easier to attach the lid opening / closing aid 1 to the knob 3.

[0037] Furthermore, in the knob storage section 6, the bottom of the tip end of the pair of arm sections 8a and 8b has a notch 82A (see Figure 4(b)) that slopes upward towards the tip. Since this notch 82A constitutes the bottom surface on the front side of the lid opening / closing aid 1, when attaching the lid opening / closing aid 1 to the knob 3, it is possible to easily attach the lid opening / closing aid 1 to the knob 3 even if the lid opening / closing aid 1 is angled downwards towards the knob 3.

[0038] The side wall of the base passage space 72B is provided with a pair of horizontally protruding protrusions 81a and 81b (see Figure 4(a)). This allows the knob 3 of the lid 22 to be stored in the knob storage space 71 of the lid opening / closing aid 1 and the lid 22 to be opened or closed, as the protrusions 81a and 81b prevent the knob 3 from coming out of the lid opening / closing aid 1, thereby improving the usability of the lid opening / closing aid 1. Furthermore, when the lid 22 is tilted while suspended in the air, the knob base 32 of the knob 3 comes into contact with the protrusions 81a and 81b, allowing the user to recognize the sensation and adjust to a stable holding position where the lid 22 is horizontal. The pair of protrusions 81a and 81b are located near the base storage space 71B, and the distance between the pair of protrusions 81a and 81b is set to be slightly larger than the diameter of the knob base 32. Therefore, when the knob base 32 of the knob 3 moves through the base passage space 72B, even if the knob base 32 hits the protrusions 81a and 81b, it is still possible to pass through. At this time, the user can feel a click when the knob base 32 hits the protrusions 81a and 81b, making it easier to recognize that the knob 3 has been placed in the knob storage space 71. In addition, since the protrusions 81a and 81b do not lock the knob 3 when it is placed in the knob storage space 71, the knob can be easily released from the knob 3 by sliding the lid opening / closing assist tool 1 while the lid 22 is placed on the pot body 21, making it easy to use.

[0039] The gripping portion 5 is provided with a constricted portion 52 having a horizontal width smaller than the horizontal width of the flange portion 51 at the top of the gripping portion 5. This allows the user to firmly grip the lid opening / closing aid 1 with the constricted portion 52, enabling stable opening and closing of the lid 22 and improving the usability of the lid opening / closing aid 1. The constricted portion 52 does not have a horizontal width smaller than the flange portion 51 around its entire circumference; instead, when the side opening 61 is viewed from the front, one of the left or right sides of the gripping portion 5, or either the right or left side, may be recessed. In this case, by aligning the fingers of the hand with the constricted portion 52, it becomes easier to position the side opening 61 facing forward, so that the side opening 61 faces the knob 3 of the lid 22, making it easier to attach the lid opening / closing aid 1 from the side (horizontal direction) and improving the usability of the lid opening / closing aid 1.

[0040] Furthermore, the present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims. For example, the side walls of the base passage space 72B and the side walls of the head passage space 72A may not have protrusions 81a and 81b. The top surface of the lid opening / closing aid 1 may not have a mark m. Furthermore, the lid opening / closing assist device 1 may be configured to be disassembled and assembled into a gripping portion 5 and a knob storage portion 6. [Explanation of Symbols]
