[Overall configuration of cooking apparatus 1]
As shown in FIGS. 1 to 3, the cooking device 1 includes an operation device having a hook 2, a gantry 11, a handle-side support structure 12, a support structure 15 opposite to the handle, a handle 3, and the like. 10.
The kettle 2 has a bottomed shape and is open upward, and cooks the food to be cooked. The hook 2 includes a hook shaft 21 protruding in the right direction D21 and the left direction D22. The gantry 11 is provided on each of the right and left sides of the hook 2, and supports the hook 2 so that the hook 2 can rotate (tilt) around the horizontal direction D2 via the handle side support structure 12 and the support structure 15. .

  More specifically, the handle side support structure 12 is provided above the right gantry 11 and rotatably supports the right side of the hook 2 via the right hook shaft 21. In addition, the handle side support structure 12 supports the operating device 10. The support structure 15 is provided above the left gantry 11 and rotatably supports the left side of the hook 2 via a left hook shaft 21 (not shown).

  At the lower part of the gantry 11, legs (not shown) constituting the grounding part of the cooking device 1 are provided.

[Operation Device 10 of First Embodiment]
The operating device 10 is operated so as to give a predetermined movement (rotation = rotation about the lateral direction D2 = rotation as a center of rotation) to the hook 2 through the handle shaft 4 by the rotation of the handle 3. The operating device 10 includes a handle 3, a handle shaft 4, a worm wheel 22, a worm 41, a handle shaft support portion 13, and a handle lock mechanism 5.

  The right shuttle shaft 21 penetrates the handle side support structure 12 and protrudes to the right. The worm wheel 22 is provided on the shuttle shaft 21 on the right side of the handle side support structure 12.

  The handle 3 is turned by an operator when the shuttle 2 is rotated. That is, when the handle 3 is turned, the hook 2 rotates around the hook shaft 21. The handle 3 is arranged on the front side on the right side of the hook 2 in consideration of the workability of an operator standing in front of the hook 2. The rotation center (axial direction) of the handle 3 (and the handle shaft 4) is also the front-rear direction D1.

The handle shaft 4 is connected to the handle 3 and is a shaft member extending in the rear direction D11 from the handle 3 and rotates in conjunction with the rotation of the handle 3. Therefore, when the handle 3 is turned, the handle shaft 4 also rotates about the front-rear direction D1. The worm 41 is provided near the rear portion of the handle shaft 4.
The handle shaft support portion 13 is provided on each of the rear direction D11 side and the front direction D12 side of the worm 41 (provided with the worm 41 sandwiched in the front-rear direction D1). The handle shaft support portion 13 is provided on the right side of the upper portion of the handle side support structure 12.

  The worm 41 is screwed to the worm wheel 22. Therefore, when the handle 3 is turned, the shuttle 2 rotates via the handle shaft 4, the worm 41, the worm wheel 22, and the right shuttle shaft 21.

[Handle lock mechanism 5]
The handle lock mechanism 5 constitutes a part of the operating device 10, and as shown in FIGS. 4 and 5, the handle 3 (rotation) is locked (locked) or unlocked (locked). It is a mechanism that switches to a state where it is released and can rotate.
Only when a predetermined unlocking operation is performed, the handle lock mechanism 5 forms an unlocked state in which the rotation of the handle 3 is unlocked. It is comprised so that it may be in the state which can form the locked state which locks rotation. The restoring force appears due to the weight of the handle lock mechanism 5. Details of the locked state and the unlocked state will be described later.

  As shown in FIGS. 4 and 5, the handle lock mechanism 5 includes a collar portion 50, a regulating member 6, a release operation portion 7, a guide member 14, and a collar 42 (see FIGS. 1 to 3). Prepare.

  The flange portion 50 is a non-circular portion extending radially outward from the handle shaft 4 and is provided on the handle shaft 4 between the handle 3 and the front handle shaft support portion 13. The flange portion 50 is a polygon having a plurality of sets of substantially parallel opposite sides 51 and 51 when viewed in the axial direction D1 of the handle shaft 4. In the present embodiment, the flange portion 50 has a regular octagon shape. That is, the collar part 50 has four sets of opposite sides 51 and 51 which are completely parallel.

  The regulating member 6 is composed of a plate-like member. The restricting member 6 has a restricting groove portion 60 that penetrates in the front-rear direction D <b> 1 and can arrange the flange portion 50. The restriction groove 60 includes a flange rotation restricting portion 61, a flange rotation permitting portion 66, and an introduction edge 63.

  The collar part rotation restricting part 61 has a hole shape penetrating in the axial direction D1 in which the collar part 50 can be arranged, and regulates the rotation of the collar part 50 when the collar part 50 is arranged. The collar part rotation restricting part 61 has an opposing inner wall 62 in which a plurality of sets of substantially parallel opposite sides 51 in the collar part 50 can be arranged. In the state where the collar part 50 is disposed on the opposed inner wall 62 of the collar rotation restricting part 61, the distance between the opposed inner wall 62 and the opposite side 51 of the collar part 50 is narrow, and therefore the collar part 50 cannot rotate.

The collar part rotation permission part 66 has a hole shape penetrating in the axial direction D1 in which the collar part 50 can be disposed, and allows the collar part 50 to rotate when the collar part 50 is disposed. In the state where the collar part 50 is disposed in the collar part rotation permission part 66, the distance between the collar part rotation permission part 66 and the outer periphery of the collar part 50 is wide, and therefore the collar part 50 can rotate.
The introductory edge 63 is a part located at the boundary between the buttocks rotation restricting portion 61 and the buttocks rotation allowing portion 66, and is rounded convex toward the inside in a front view.

  Further, the left side wall of the regulating member 6 faces the guide member 14 (described later) in close proximity and functions as a guide wall portion 68. The lower right portion of the regulating member 6 faces a pressing portion 73 (details will be described later) of the release operation portion 7 and functions as a pressed portion 69. The pressed portion 69 is formed in an arc shape, and the inner end portion thereof is disposed at a position depending from the rotation center of the handle shaft 4. This facilitates the design of a configuration in which the pressed portion 69 is easily pressed by the pressing portion 73.

[Release Operation Unit 7 in First Embodiment]
The release operation unit 7 in the first embodiment is a part where a lock release operation is performed mainly by the hand or arm of the handle operator who operates the handle 3. The release handle 71, the fulcrum shaft 72, and the pressing unit 73. And a fulcrum shaft support portion 74 and a rotation restricting piece 75.
As shown in FIG. 4, the release handle 71 is a rod-like handle used at the time of unlocking operation, and is operated by the operator's hand or arm to rotate around the fulcrum shaft 72 as a rotation center. The release handle 71 includes a grip portion 711 to be gripped on the distal end side and a rotation base portion 712. The pressing portion 73 is made of a plate-shaped (square bar-shaped) member that is connected to the lower portion of the release handle 71. The release handle 71 extends substantially in the vertical direction D3 and is disposed on the left side of the restricting member 6. The pressing portion 73 extends in the right direction D <b> 21 and is disposed below the regulating member 6. The fulcrum shaft 72 functions as a fulcrum for the release handle 71 and the pressing portion 73 to be connected. As shown in FIGS. 2 and 3, the fulcrum shaft 72 is disposed on the left side of the handle-side support structure 12 in a plan view and extends in the axial direction D1 (front-rear direction D1).

  The upper part of the grip portion 711 of the release handle 71 is bent so as to be positioned in the space above the handle shaft 4. The upper space of the handle shaft 4 is generally a space that is not effectively utilized. In the present embodiment, the space above the handle shaft 4 is effectively utilized as an arrangement space above the grip portion 711 of the release handle 71. Also, as shown in FIG. 4, even in the unlocked state, the amount by which the grip portion 711 of the release handle 71 protrudes to the left side can be minimized (it can be accommodated in the space between the handle shaft 4 and the shuttle 2). Therefore, design changes such as expanding the space between the handle shaft 4 and the shuttle 2 can be suppressed.

Two fulcrum shaft support portions 74 are provided so as to be separated from each other in the front-rear direction D1 and connected to the handle side support structure 12 on the left side. The fulcrum shaft support portion 74 supports the fulcrum shaft 72 so as to be rotatable in two places apart from each other in the front-rear direction D1.
The rotation restricting piece 75 is disposed on the left side of the release handle 71 of the release operation unit 7 and restricts the release handle 71 from rotating too much counterclockwise during the unlocking operation. Specifically, when the release handle 71 rotates too far counterclockwise, the rotation base 712 of the release handle 71 comes into contact with the rotation restriction piece 75 (indicated by a two-dot chain line in FIG. 4). Cannot rotate further counterclockwise.

  The guide member 14 is disposed in the vicinity of the guide wall portion 68 formed of the left side wall of the regulating member 6. The guide member 14 is disposed in front of the handle side support structure 12 and connected to the handle side support structure 12.

  As shown in FIGS. 1 to 3, the collar 42 is coupled to the flange 50 so as to sandwich the flange 50 and the restriction groove 60 positioned in the restriction groove 60 of the restriction member 6 in the axial direction D <b> 1. Examples of the connection form between the collar 42 and the flange 50 include welding and bolt fastening. The collar 42 restricts the movement of the restricting member 6 in the axial direction D1 (front-rear direction D1). Further, the collar 42 covers most of the restriction groove portion 60 of the restriction member 6 (particularly, the collar portion rotation restriction portion 61). For the purpose of maintaining the unlocked state, the operator may perform an abnormal operation of pinching an object between the buttocks rotation restricting portion 61 and the buttocks 50. However, if the collar 42 covers most of the restriction groove 60, the abnormal operation can be suppressed.

[Locked state in the first embodiment]
In the first embodiment, the locked state is formed as follows. When the release handle 71 of the release operation unit 7 is not operated, as shown in FIG. 5A, the pressing unit 73 is spaced downward from the regulating member 6 and is not in contact (pressing) with the regulating member 6. . Therefore, the regulating member 6 tries to move downward most according to its own weight. When the collar part 50 is located in the collar part rotation regulation part 61, the regulation member 6 moves downward until the upper part of the collar part 50 contacts the collar part rotation regulation part 61. Further, as shown in FIG. 5B, when the collar portion 50 is positioned at the collar portion rotation permitting portion 66, the collar portion 50 is moved along the downward movement of the regulation member 6, and the collar portion 50 is regulated by the collar portion rotation regulating portion 61. Try to move on.

  Further, depending on the rotation position of the collar part 50 (that is, the rotational position of the handle 3 and the handle shaft 4), the collar part 50 located on the collar part rotation permission part 66 is caught and cannot move to the collar part rotation restricting part 61. There is a case. However, in that case, by turning the handle 3 a little to rotate the collar part 50, the collar part 50 can enter the collar part rotation restricting part 61. Can be arranged. In addition, since the rounded introduction edge 63 is provided, the flange 50 located in the flange rotation permitting portion 66 is not easily caught and easily moved to the flange rotation restricting portion 61.

  Further, when the restricting member 6 is caught by the flange portion 50 and is not completely lowered (the locked state is not formed), the handle 3 erroneously rotates due to any factor in this state. Even if it starts, the restriction | limiting member 6 falls below to the place which can be carried out naturally with dead weight with the introduction edge part 63 provided in the restriction | limiting member 6, and can form a locked state. In this way, even if the handle 3 is not intentionally operated, the locked state is naturally formed when the handle 3 starts to rotate again.

  In the locked state, the distance between the opposite side 51 of the flange 50 and the opposed inner wall 62 of the flange rotation restricting portion 61 is small. For this reason, the flange 50 can hardly rotate, and the handle 3 can hardly rotate via the flange 50 and the handle shaft 4. That is, the rotation of the handle 3 is locked. Since the locked state is maintained as long as the handle release operation by the operation of the release handle 71 is not performed, it is safe.

[Unlocked state in the first embodiment]
In the first embodiment, the unlocked state is formed as follows. As shown in FIG. 4, when the release handle 71 of the release operation unit 7 is operated and rotates counterclockwise, the pressing unit 73 also rotates counterclockwise about the fulcrum shaft 72. Accordingly, as shown in FIGS. 4 and 5B, the pressing portion 73 presses the pressed portion 69 at the lower right portion of the regulating member 6 from the lower right to the upper left. Thereby, the regulating member 6 tries to move to the upper left. However, a guide member 14 is disposed on the left side of the regulating member 6. Therefore, after the guide wall portion 68 formed of the left side wall of the restriction member 6 contacts the guide member 14, the restriction member 6 cannot move in the left direction D22. Therefore, the restricting member 6 moves in the upward direction D31 with the guide member 14 restricting the moving direction to the up and down direction D3. As a result, the collar part 50 located in the collar part rotation restricting part 61 moves to the collar part rotation permission part 66. Since the rotation of the flange portion 50 located in the flange rotation permission portion 66 is not restricted, the rotation of the handle 3 connected via the handle shaft 4 is also not restricted. That is, the lock of the handle 3 is released. Note that the pressing portion 73 does not contact the collar 42 in the unlocked state.

[Transition from the unlocked state to the locked state in the first embodiment]
In the first embodiment, the unlocked state is formed when the release handle 71 of the release operation unit 7 is operated and rotated counterclockwise. On the other hand, when it becomes unnecessary to release the lock, the release handle 71 of the release operation unit 7 is not operated. For example, when the operator rotates the release handle 71 clockwise, the collar part 50 arranged in the collar part rotation permission part 66 moves to the collar part rotation restricting part 61, and the locked state is formed again.

  By the way, it is possible that the operator forgets the operation of changing to the locked state. On the other hand, in the present embodiment, the restoring force appears due to the dead weight of the handle lock mechanism 5. For example, due to the weight of the restricting member 6 and the position of the center of gravity of the release handle 71, a restoring force that causes the release operation unit 7 to rotate clockwise appears. Therefore, the release operation unit 7 (particularly, the connected release handle 71 and the pressing unit 73) rotates clockwise even if there is no drive source due to electric power or the elastic force of the elastic member.

  Note that, as described above, when the collar portion 50 located on the collar rotation permission portion 66 is caught by the rotation position of the collar portion 50, the collar portion 50 is rotated by rotating the handle 3 a little to rotate the collar portion 50. It can arrange | position to the collar part rotation control part 61 (that is, a locked state is formed).

[Effects of First Embodiment]
According to the operating device 10 of the first embodiment, for example, the following effects are exhibited.
The operating device 10 according to the first embodiment includes a handle 3, a handle shaft 4 that interlocks with the rotation of the handle 3, and a handle lock mechanism 5 that locks the rotation of the handle 3. The handle lock mechanism 5 is operated so as to give a predetermined movement to the hook 2 via the handle, and the handle lock mechanism 5 unlocks the rotation of the handle 3 only when a predetermined lock release operation is performed. When the unlocked state is formed and the unlocking operation is stopped, the locked state in which the rotation of the handle 3 is locked can be formed by the spontaneous restoring force.

  Therefore, if the unlocking operation is intentionally performed, the hook 2 can be moved. On the other hand, by stopping the unlocking operation, the locked state can be formed without intentionally forming the locked state. Because it is safe. Since no electric power is used, the handle 3 can be locked without being affected by electrical malfunctions (energization failure, power failure, etc.).

  In the operating device 10 according to the first embodiment, the restoring force is expressed due to the weight of the handle lock mechanism 5. Therefore, the restoring force can be expressed and the locked state can be formed without using a mechanical drive source (such as an elastic member) for expressing the restoring force.

  In the operating device 10 of the first embodiment, the handle lock mechanism 5 includes a non-circular flange 50 extending radially outward from the handle shaft 4 and a restriction member 6 having a restriction groove 60 in which the flange 50 can be disposed. And the restriction groove portion 60 rotates the flange portion 50 when the flange portion 50 is disposed, and the flange rotation restriction portion 61 that restricts the rotation of the flange portion 50 when the flange portion 50 is disposed. And a collar rotation permission portion 66 to be permitted.

  Therefore, by changing the arrangement position of the flange portion 50 in the restriction groove portion 60, the rotation of the flange portion 50, that is, the restriction and allowance of the rotation of the handle 3 can be easily changed.

  In the operating device 10 according to the first embodiment, the flange portion 50 is a polygon having a plurality of sets of substantially parallel opposite sides 51 when viewed in the axial direction D1 of the handle shaft 4, and the flange rotation restriction portion 61. Has opposing inner walls 62 on which a plurality of sets of substantially parallel opposite sides 51 can be arranged.

  Therefore, since there are a plurality of patterns in which the collar portion 50 is arranged on the collar rotation restricting portion 61, an operation of rotating the handle 3 and arranging the collar portion 50 on the collar rotation restricting portion 61 in the process of forming the locked state (that is, , Operation to form a locked state) is easy.

[Operation Device 10A of Second Embodiment]
Next, an operating device 10A according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a front view showing the behavior when the shuttle operating device 10A of the second embodiment transitions from the locked state of the handle to the unlocked state (corresponding to FIG. 4). FIG. 7 is a right side view showing a lower half of the release operation portion 7A in the operation device 10A for the shuttle according to the second embodiment in the locked state. FIG. 8 is a right side view showing the lower half of the release operation portion 7A in the shuttle operating device 10A of the second embodiment in the unlocked state.

  In the second embodiment, differences from the first embodiment will be mainly described. Therefore, detailed description of the same (or equivalent) configuration as in the first embodiment is omitted. Moreover, about the point which is not demonstrated especially in 2nd Embodiment, description of 1st Embodiment is applied or used suitably. In the second embodiment, the same effect as that of the first embodiment is achieved.

  In the first embodiment described above, the release operation unit 7 has the release handle 71 and is a part where the lock release operation is mainly performed by the hand or arm of the handle operator who operates the handle 3. In contrast, in the second embodiment, as shown in FIGS. 6 to 8, the release operation portion 7 </ b> A has a foot pedal 8, and a lock release operation can be performed by a handle operator's foot operating the handle 3. This is the part to be performed.

  The release operation unit 7A in the second embodiment includes a foot pedal 8 that moves when it is stepped on by a handle operator's foot, and a regulation member moving unit 9 that mechanically moves the regulation member 6 as the foot pedal 8 moves. And comprising. In the release operation portion 7A, when the foot pedal 8 is stepped on, the restricting member 6 is moved by the restricting member moving portion 9, and the collar portion 50 disposed in the collar portion rotation restricting portion 61 is disposed in the collar portion rotation permitting portion 66. It is configured to be.

  As shown in FIGS. 7 and 8, the foot pedal 8 includes a base portion 81, a footboard portion 82, a hinge portion 83, and a stopper portion 84. The base 81 is a base formed at the bottom of the foot pedal 8. The tread plate portion 82 is a plate-like portion that rotates within a predetermined range with respect to the base portion 81. The hinge part 83 connects the base part 81 and the foot board part 82 so that rotation is possible. The stopper portion 84 is disposed between the inner surface of the base portion 81 and the inner surface of the tread plate portion 82. The stopper portion 84 is a portion that, when the tread plate portion 82 is stepped on and approaches the base portion 81, the tread plate portion 82 abuts and prevents the tread plate portion 82 from further approaching the base portion 81. The stopper portion 84 may be configured to be adjustable in height. In that case, by adjusting the height of the stopper part 84, the position of the stopper part 84 in the vertical direction D3 where the tread board part 82 abuts, that is, the depth at which the tread board part 82 can be stepped on can be adjusted.

  As shown in FIGS. 6 to 8, the regulating member moving unit 9 includes a pressing unit 73, a rotation base 712, a fulcrum shaft 72, a force base 76, and a connecting rod structure 90 from the top. . The lower part of FIG. 6 is connected to the upper part of FIG. 7 or FIG. 8, but the direction of FIG. 6 is different from that of FIGS. 7 and 8 by 90 degrees. Since the pressing part 73, the rotation base part 712, and the fulcrum shaft 72 are the same as that of 1st Embodiment, description is abbreviate | omitted. The force point base portion 76 is a portion that is disposed on the opposite side (left direction D22) from the pressing portion 73 with the fulcrum shaft 72 interposed therebetween, and is configured integrally with the pressing portion 73.

  The connecting rod structure 90 is a rod-like structure in an overall view that connects the force point base portion 76 integral with the pressing portion 73 and the tread plate portion 82 of the foot pedal 8. The structure of the connecting rod structure 90 is such that the movement (particularly, the movement amount) of the foot pedal 8 due to depression of the foot pedal 8 is transmitted to the pressing portion 73 to move the pressing portion 73, and the locked state and the unlocked state are changed. If the transition can be realized, it is not limited. Note that the movement of the foot pedal 8 is not limited to a linear movement, and includes, for example, a curved movement, rotation, rotation, zigzag movement, and the like. In the present embodiment, the connecting rod structure 90 includes a force point connecting portion 91, a force point shaft 92, an upper rod-like portion 93, a turnbuckle 94, a lower rod-like portion 95, and a pedal connecting structure portion 96.

Since the restricting member moving part 9 in the second embodiment includes the turnbuckle 94, it is easy to change the total length of the restricting member moving part 9.

  In the second embodiment, a rotation restricting function is provided by the rotation base 712 coming into contact with the upper end of the rotation restricting piece 75, and this function is used as a guide for adjusting the turnbuckle 94. For example, the turnbuckle 94 is adjusted so that when the foot pedal 8 is stepped on, the rotation base portion 712 just hits the upper end of the rotation restricting piece 75.

  According to the release operation unit 7A in the second embodiment configured as described above, the locked state and the unlocked state can be changed as follows. In the following description, the description of the first embodiment is used to simplify the description as appropriate.

[Locked state in the second embodiment]
In the second embodiment, similarly to the case where the release handle 71 in the first embodiment is not operated, the restricting member 6 is moved downward and a locked state is formed (see also FIG. 5A). In the second embodiment, since the locked state is maintained unless a handle release operation is performed by depressing the foot pedal 8, it is safe.

[Unlocked state in the second embodiment]
In the second embodiment, the unlocked state is formed as follows. As shown in FIG. 7, the foot pedal 8 is stepped on from the state in which the foot plate portion 82 of the foot pedal 8 is positioned upward, as shown in FIG. 8, and the foot plate portion 82 rotates downward. When moved, the movement of the tread plate portion 82 is transmitted to the pressing portion 73 via the connecting rod structure 90 and the power point base portion 76. Thereby, the pressing part 73 and the rotation base part 712 rotate counterclockwise around the fulcrum shaft 72 as a rotation center. Accordingly, as shown in FIG. 6, the pressing portion 73 presses the pressed portion 69 at the lower right portion of the regulating member 6 from the lower right to the upper left. As a result, the regulating member 6 moves in the upward direction D31, and the handle 3 is unlocked as in the case where the handle release operation is performed by the operation of the release handle 71 in the first embodiment (FIG. 5 ( See also B)).

[Transition from the unlocked state to the locked state in the second embodiment]
In the second embodiment, when unlocking is no longer necessary in the unlocked state, the foot pedal 8 is not depressed. Thereby, the regulating member 6 and the pressing portion 73 move downward, while the power point base portion 76 and the connecting rod structure 90 move upward. Thereby, the footplate part 82 of the foot pedal 8 connected to the lower end part of the connecting rod structure 90 moves upward. Moreover, the collar part 50 arrange | positioned at the collar part rotation permission part 66 moves to the collar part rotation control part 61, and a locked state is formed again.

  By the way, it is possible that the operator forgets the operation of changing to the locked state. On the other hand, in the present embodiment, the restoring force appears due to the dead weight of the handle lock mechanism 5. For example, due to the dead weight of the regulating member 6 and the position of the center of gravity of the connecting rod structure 90, a restoring force that causes the pressing portion 73 of the release operation portion 7A and the force point base portion 76 integrated therewith to rotate clockwise appears. To do. Therefore, even if there is no drive source resulting from electric power or the elastic force of an elastic member, the pressing part 73 and the power point base part 76 of the release operation part 7A rotate clockwise. Along with this, the connecting rod structure 90 connected to the force point base portion 76 moves upward, and the footplate portion 82 of the foot pedal 8 connected thereto also moves upward.
