The handle main body 20 and the rotation operation portion 30 are formed by pressing a metal plate.

[0013] In the following description, the longitudinal direction of the handle 10 in the closed state is defined as the Y direction, the central axis direction of the cooker 50 to which the handle 10 is attached is defined as the Z direction, and the short-side direction, which is the width direction of the handle 10, is defined as the X direction. The X, Y, and Z directions are orthogonal to each other. Also, in the Y direction, with the handle 10 attached to the cooker 50, the side of the handle 10 closer to the cooker 50 is defined as the front side, and the side farther from the cooker 50 is defined as the rear side. Further, in the Z direction, the side from the rotation operation portion 30 toward the handle main body 20 is defined as the upper side, and the side from the handle main body 20 toward the rotation operation portion 30 is defined as the lower side. Also, the open state of the handle 10 is a state in which the rotation operation portion 30 and the handle main body 20 form a V shape as shown in FIG. 2, and the closed state of the handle 10 is a state in which the rotation operation portion 30 is in a straight line with the handle main body 20 as shown in FIG. 3.

[0014] The handle main body 20 has a shape that is long in the Y direction and is formed in a U shape when viewed from the Y direction. Specifically, the handle main body 20 includes a ceiling wall portion 21, two side wall portions 22, and two inclined wall portions 23. The ceiling wall portion 21 is in the shape of a rectangular plate that is long in the Y direction. The ceiling wall portion 21 is provided with an operation portion through hole 21a. The operation portion through hole 21a is located on the rear side of a hook through hole 23a, which will be described later. The operation portion through hole 21a is formed as an elongated hole that is long in the Y direction and is located on the front side of the center of the ceiling wall portion 21 in the X direction.

[0015] Each inclined wall portion 23 is located at both ends of the ceiling wall portion 21 in the X direction and connects the ceiling wall portion 21 and the side wall portion 22. Each inclined wall portion 23 inclines so as to proceed downward as it goes toward the outside in the X direction. Each inclined wall portion 23 has a hook through hole 23a. The hook through hole 23a is formed as a through hole at the front end portion of each inclined wall portion 23 in the Y direction. Each hook through hole 23a is formed as an elongated hole that is long in the Y direction and is formed over the entire area of the inclined wall portion 23 in the X direction. The two hook through holes 23a are arranged side by side in the X direction. The length of each hook through hole 23a in the Y direction is shorter than the length of the operation portion through hole 21a in the Y direction. The width length of each hook through hole 23a in the X direction is larger than the width length of the operation portion through hole 21a in the Y direction.

[0016] Each side wall portion 22 is connected to the lower end portion of each inclined wall portion 23 and extends in a direction orthogonal to the ceiling wall portion 21. Each side wall portion 22 includes a cooker receiving recess 22a, a slope side wall portion 22b, and a low side wall portion 22c. The slope side wall portion 22b is located on the front side of the center of the handle 10 in the Y direction. The slope side wall portion 22b has a substantially triangular shape in which the height in the Z direction increases as it goes forward.

[0017] The cooker receiving recess 22a is partitioned by the front end portion of the slope side wall portion 22b and the front lower side portion of the inclined wall portion 23, and has a substantially L-shaped plate shape that opens forward and downward.

[0018] As shown in FIG. 7, the cooker receiving recess 22a includes a contact portion 22d and a gap portion 22e. The contact portion 22d is located at the front lower end portion of the slope side wall portion 22b and contacts the outer surface 50o of the side wall portion 52 of the cooker 50 in a state where the handle 10 is attached to the cooker 50. The gap portion 22e is located above the contact portion 22d, and when the handle 10 is attached to the cooker 50, the upper edge portion 53 of the cooker 50 is located. The gap portion 22e is formed at the corner of the substantially L-shaped cooker receiving recess 22a. The gap portion 22e has a rectangular shape and is located below the hook passage hole 23a.

[0019] As shown in FIGS. 2 and 3, the low side wall portion 22c is located behind the slope side wall portion 22b. The low side wall portion 22c is formed at the same height as the height of the rear end portion of the slope side wall portion 22b. The low side wall portion 22c is formed over a range extending from the rear end portion of the handle 10 to the front side of the center in the Y direction.

[0020] As shown in FIGS. 5 and 8(D), the slide plate 55 is configured to be slidable in the Y direction within the handle main body portion 20, and is configured to be able to press a hook portion 34, which will be described later, toward the contact portion 22d by being slid forward. The slide plate 55 has a rectangular plate shape that is long in the Y direction and is configured to be slidable on the lower surface of the ceiling wall portion 21. The thickness of the slide plate 55 is formed to be thinner than the thickness of the ceiling wall portion 21. The operation of the slide plate 55 will be described later.

[0021] The slide operation portion 58 is fixed to the slide plate 55 and is configured as a knob that can be slid in the Y direction by a user from the outside through the operation portion passage hole 21a. As shown in FIG. 8(F), the slide operation portion 58 includes a columnar shaft portion 58a that passes through the operation portion passage hole 21a, and disk-shaped disk portions 58b and 58c having a diameter larger than that of the shaft portion 58a and fixed to both end surfaces of the shaft portion 58a. The shaft portion 58a extends in a direction orthogonal to the ceiling wall portion 21 and passes through the through hole 55h of the slide plate 55 and the operation portion passage hole 21a. The disk portion 58b is located on the upper surface of the ceiling wall portion 21 and is pinched by a user's finger when being slid. The disk portion 58c is located on the lower surface of the slide plate 55 and holds the slide operation portion 58 in a state of preventing it from coming off the slide plate 55.

[0022] As shown in FIGS. 2 and 3, the rotation operation unit 30 is configured to be openable and closable by rotating with respect to the handle main body 20 about the rotation shaft portion 40. As shown in FIG. 4, the rotation operation unit 30 includes a bottom wall portion 31, two side wall portions 32, and two inclined wall portions 33. The bottom wall portion 31 has a rectangular plate shape that is long in the Y direction and faces the ceiling wall portion 21 when the handle 10 is in the closed state. A plurality of through holes 31h are formed in the bottom wall portion 31. The two through holes 31h are formed at positions separated in the Y direction. The through holes 31h are formed in a circular shape and discharge the water accumulated in the rotation operation unit 30 to the outside. Further, the through holes 31h can also be used as holes through which screws for attaching optional components pass.

[0023] Each inclined wall portion 33 is located at both ends in the X direction of the bottom wall portion 31 and connects the bottom wall portion 31 and the side wall portion 32. Each inclined wall portion 33 is inclined so as to go upward as it goes outward in the X direction. Each side wall portion 32 is connected to the upper end portion of each inclined wall portion 33 and extends in a direction orthogonal to the bottom wall portion 31. In the X direction, each side wall portion 32 is located inside the X direction by the thickness of the side wall portion 32 compared to each side wall portion 22.

[0024] Each side wall portion 32 includes a low side wall portion 32a, a slope side wall portion 32b, and a hook portion 34. The slope side wall portion 32b is located in front of the center in the Y direction of the handle 10. The slope side wall portion 32b is formed such that the height in the Z direction increases as it goes forward. A through hole 32c through which the rotation shaft portion 40 passes is formed in the slope side wall portion 32b. The through hole 32c is located above the low side wall portion 32a. The outer surface in the X direction of the slope side wall portion 32b is positioned so as to face the inner surface in the X direction of the slope side wall portion 22b.

[0025] The lower side wall portion 32a is located behind the slope side wall portion 32b. The lower side wall portion 32a is formed at the same height as the height of the rear end portion of the slope side wall portion 32b. The lower side wall portion 32a is formed over a range extending from the rear end portion of the handle 10 to the front side of the central portion in the Y direction.

[0026] As shown in FIGS. 4 and 7, the hook portions 34 are arranged to face each other in the X direction, and receive a force F1 (see FIG. 7) pushed by the slide plate 55, and sandwich the side wall portion 52 of the cooker 50 between them and the contact portion 22d of the handle main body portion 20. The hook portion 34 is located at the front end of the slope side wall portion 32b and is formed in a plate shape on the YZ plane. The hook portion 34 includes an arm portion 34a and a hook pressing portion 34b. The arm portion 34a has an L shape inverted in the Z direction. The arm portion 34a includes a first extending portion 341 extending in the Y direction from the front upper end of the slope side wall portion 32b, and a second extending portion 342 extending downward from the front end portion of the first extending portion 341. The upper end surface of the first extending portion 341 is a slide contact surface 343 on which the slide plate 55 slides. The slide contact surface 343 is inclined with respect to the Y direction so as to go upward as it advances forward. The inclination angle of the slide contact surface 343 increases as the rotation operation portion 30 opens with respect to the handle main body portion 20. Due to the inclination of the slide contact surface 343, as the slide plate 55 sliding forward slides on the slide contact surface 343, a force F1 that rotates the hook portion 34 in a direction approaching the inner surface 50i of the side wall portion 52 of the cooker 50 acts.

[0027] Each hook pressing portion 34b is configured to press the side wall portion 52 of the cooker 50 toward each contact portion 22d. The hook pressing portion 34b is connected to the rear end of the second extending portion 342 and is formed by being bent inward in the X direction with respect to the second extending portion 342. The hook pressing portion 34b is plate-shaped on the XZ plane, and in this example, is rectangular plate-shaped. The two hook pressing portions 34b are formed so as to be arranged with a gap in the X direction between the two arm portions 34a in the X direction. Each hook pressing portion 34b is located inside each contact portion 22d in the X direction.

[0028] As shown in FIGS. 2 and 4, the rotary shaft portion 40 enables the handle main body portion 20 and the rotation operation portion 30 to rotate relative to each other about a rotary shaft extending in the X direction. The rotary shaft portion 40 has a columnar shape that penetrates each slope side wall portion 22b, 32b.

[0029] Next, a method of attaching the handle 10 to the cooker 50 will be described. First, as shown in FIG. 2, the slide operation portion 58 is positioned at the rear end within the operation portion through hole 21a. In this state, the slide plate 55 does not contact the hook portion 34, and the rotation operation portion 30 can rotate about the rotary shaft portion 40 with respect to the handle main body portion 20. The handle 10 is set in a V-shaped open state. In this open state, as shown in FIG. 6, each contact portion 22d is brought close to or into contact with the outer surface 50o of the side wall portion 52 of the cooker 50, and the upper edge portion 53 of the cooker 50 is positioned within the gap portion 22e of the cooker receiving recess 22a. At this stage, a part of the arm portion 34a of the hook portion 34 protrudes from the operation portion through hole 21a. Then, as shown by the arrow A1 in FIG. 2, the rotation operation portion 30 is rotated toward the handle main body portion 20 about the rotary shaft portion 40 so that the angle of the rotation operation portion 30 with respect to the handle main body portion 20 becomes smaller. As a result, the rotation operation portion 30 is oriented along the handle main body portion 20, and the handle 10 is closed.

[0030] Next, the slide operation unit 58 is slid forward within the operation unit through-hole 21a. As a result, as shown by arrow A2 in Fig. 6, the slide plate 55 moves forward, slides on the slide contact surface 343 which is the upper end surface of the hook portion 34, and pushes down the hook portion 34. Thereby, as shown in Fig. 7, the hook pressing portion 34b comes close to and contacts the inner surface 50i of the side wall portion 52 of the cooker 50. In this state, the side wall portion 52 of the cooker 50 is sandwiched between the hook pressing portion 34b and the contact portion 22d in the thickness direction, and the handle 10 is held by the cooker 50 in a held state. In this held state, the slide operation unit 58 is positioned slightly forward of the center of the operation unit through-hole 21a in the Y direction, and the front end portion of the slide plate 55 is positioned near the center of the slide contact surface 343. Also, in this held state, the slide plate 55 is held in a state where the rotation of the hook pressing portion 34b in the direction away from the side wall portion 52 is restricted through contact with the hook portion 34. Thereby, even if the user releases their hand from the handle 10, the held state of the handle 10 is maintained. The position of the front end portion of the slide plate 55 in the Y direction in the held state changes depending on the shape such as the thickness of the side wall portion 52 of the cooker 50. Specifically, as the side wall portion 52 becomes thinner, the slide operation unit 58 in the held state is positioned forward. In this way, regardless of the shape of the cooker 50, the handle 10 can be attached to the cooker 50. In the held state, it becomes possible to carry the cooker 50 while gripping the handle 10.

[0031] When removing the handle 10 from the cooker 50, the slide operation unit 58 is slid backward within the operation unit through-hole 21a. Along with this, the slide plate 55 moves backward and retracts from the slide contact surface 343. Thereby, it becomes possible to shift the handle 10 from the closed state to the open state. After making the handle 10 into the open state, the handle 10 is removed from the cooker 50. The description of the method for attaching and detaching the handle 10 to and from the cooker 50 ends here.

[0032] (Effect) According to the above-described embodiment, the following effects can be achieved. (1) The handle 10, which is an example of a detachable device, is configured to be detachable from the cooker 50, which is an example of an object to be attached. The handle 10 has a contact portion 22d that contacts the outer surface 50o, which is an example of the first surface of the cooker 50, in a state where the handle 10 is attached to the cooker 50, and a handle main body portion 20 that extends in the Y direction, which is an example of the extending direction. The handle 10 has a hook portion 34 that contacts the inner surface 50i, which is an example of the second surface, on the side opposite to the outer surface 50o of the cooker 50 in a state where the handle 10 is attached to the cooker 50. A rotation operation portion 30 configured to be rotatable with respect to the handle main body portion 20 about a rotation axis portion 40, which is a rotation axis extending in the X direction, which is an example of the width direction intersecting the Y direction. A slide plate 55, which is an example of a slide portion, is configured to be slidable in the Y direction with respect to the handle main body portion 20, and is held in a state where the slide contact surface 343 of the hook portion 34 is pressed so that the hook portion 34 is pressed against the inner surface 50i by sliding toward the hook portion 34 side. A slide operation portion 58 fixed to the slide plate 55 and slidably operated by the user is provided. The slide contact surface 343 is inclined with respect to the Y direction, and the slide plate 55 that has slid forward slides so that a force F1 is applied in a direction approaching the inner surface 50i with respect to the hook portion 34. The handle main body portion 20 includes a hook passage hole 23a through which a part of the hook portion 34 passes when the rotation operation portion 30 is opened so that the angle with respect to the handle main body portion 20 increases, and an operation portion passage hole 21a formed as a long hole extending in the Y direction through which the slide operation portion 58 passes and enabling the slide operation portion 58 to move in the Y direction with respect to the handle main body portion 20. According to this configuration, the handle 10 can be easily attached to and detached from the cooker 50 regardless of the shape (mainly thickness) of the cooker 50.

[0033] (2) The cooker 50 is made of metal and houses food and opens upward. The handle 10 is detachable from the upper end portion of the cooker 50 and is made of metal that can be gripped by the user in a state where it is attached to the upper end portion of the cooker 50. According to this configuration, the handle 10 can be easily attached to and detached from the cooker 50 regardless of the shape (mainly the thickness) of the cooker 50.

[0034] (3) The cooker handle set 1 includes a handle 10 and a cooker 50. According to this configuration, the handle 10 can be easily attached to and detached from the cooker 50 regardless of the shape (mainly the thickness) of the cooker 50.
