Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking container gripper for gripping a cooking container such as a pot, and more particularly, a cooking container gripper suitable for gripping a relatively shallow pot used when cooking ingredients for rice bowl dishes. Regarding tools.

As an apparatus for efficiently producing rice bowls such as katsudon and oyakodon on a commercial scale, for example, Patent Document 1 proposes a rice bowl processing machine. This rice bowl processing machine is a device that heats and cooks the ingredients of a rice bowl by heating from the lower side or the upper side of the pots or both while conveying a large number of pots arranged in parallel in a fixed direction. Ingredients, seasonings, etc. corresponding to the type of bowl are put into the pot at an appropriate position in the conveying process, and the cooking of the ingredients is completed when the pot just reaches the end of the conveying process. It is

The ingredients that have been cooked are then placed on top of the rice, etc., piled up in the bowl to form a bowl of rice. It is done manually. That is, the pot used in the rice bowl processing machine is provided with a handle so that the operator can easily hold it, as can be seen in the pot shown by number 26 in FIG. 8 of Patent Document 1. Hold the handle to lift and move the pot, and turn it over on the bowl filled with rice, etc., or shake it while tilting it at a large angle to transfer the cooked ingredients from the pot onto the rice. there is

However, if the pot has a handle, for example, when setting a large number of pots in a rice bowl processing machine, an extra space is required for the handle. In addition, the protruding handle is a major obstacle when cleaning or storing the pot after cooking.

However, there are many pots without handles, and some pot holders for pots without handles have been proposed. For example, Patent Literature 2 discloses a cooking handle provided with a clamping piece and a clamping piece at the tip of a pair of members whose tips are supported so that they can approach and separate like pliers. However, in this cooking handle, the holding piece and the holding piece have a special shape, and the cooking container is provided with a horizontal flange that spreads outward at the upper end of the container and a vertical flange that rises further upward from the horizontal flange. It is specialized for , and it is not something that can hold pots of any shape.

FIG. 1 of Patent Document 3 also discloses a pliers-type cooking container gripper as a prior art. In order to stably grip the cooking container using this gripping tool, one of the pair of support pieces is inserted in the depth direction of the cooking container. If the pot has a shallow bottom and the food to be cooked is filled up to the relatively upper part of the pot, the tip of the support piece comes into contact with the food to be cooked in the pot, which is sanitary. In addition to the problem of sexuality, there is the inconvenience of staining oneself. Furthermore, this cooking container gripper is mainly intended for gripping the cooking container when the cooking container is taken out of, for example, an oven range, etc., and it is assumed that the cooking container will be turned over or tilted and shaken greatly. It is not robust enough in terms of stability.

Japanese Patent No. 3725138 JP-A-2001-145578 Utility Model Registration No. 3099535

SUMMARY OF THE INVENTION The present invention has been made to overcome the drawbacks of the conventional cooking container gripper described above. To provide a cooking container gripper capable of maintaining a stable gripping state even when the cooking container is turned over while gripping the container, or even when the cooking container is tilted and shaken.

As a result of earnest research efforts to solve the above problems, the present inventor changed the conventional idea of gripping the cooking container by sandwiching it between the surfaces of a pair of gripping portions, and changed the pair of gripping portions. Depth at which the tip of the gripping tool is inserted into the cooking container by gripping the cooking container by sandwiching the cooking container between the linearly connected convex portions by drawing a circular arc. can be made shallow, and a stable gripping tool capable of sufficiently coping with inclination and reversal at a large angle can be realized, and the present invention has been completed.

That is, the present invention includes an inner abutment body having an outward convex portion linearly extending in an arc, an outer abutment body having an inward convex portion linearly extending in an arc, and the inner abutment body. a gripping position where the outer contact body is gripped with the outward convex portion and the inward convex portion being close to each other and the side wall of the cooking container, which is the object to be grasped, is sandwiched between the two convex portions; The object is to solve the above problems by providing a cooking vessel gripper having a support means for supporting the inwardly protruded portion so as to be relatively movable between a standby position in which the portion and the inward convex portion are spaced apart from each other.

As described above, the cooking vessel gripping tool of the present invention has an outward convex portion that is linearly connected in an arc drawn by the inner contact body, and an inward convex portion that is similarly linearly connected in an arc by the outer contact body. The side wall of the cooking container is sandwiched between and is gripped, and the outward convex part and the inward convex part are both convex parts that draw a circular arc and are continuous linearly, so the cooking container is characterized by this It is gripped by being sandwiched between the linear projections that draw a pair of upper and lower circular arcs.

In this specification, the terms "inside" and "outside" refer to being relatively inside or outside with respect to the arc drawn by the outward convex portion and the inward convex portion of the inner contact body and the outer contact body. Similarly, outward and inward refer to whether the inner contact body and the outer contact body are facing outward or inward from the circular arc drawn by the outward and inward convex portions of the inner contact body and the outer contact body. and In addition, when the cooking container is gripped, the inner contact body is positioned inside the side wall of the cooking container, and the outer contact body is positioned outside the side wall of the cooking container. It can be said that the outward convex portion is a convex portion that contacts the inner peripheral surface of the side wall of the cooking container when the cooking container is gripped, and the inward convex portion is a convex portion that contacts the outer peripheral surface.

Further, the expression that the outward convex portion or the inward convex portion draws a circular arc and is connected linearly means that the line connecting the vertices of the outward convex portion or the inward convex portion forms a circular arc. The apexes of the convex portion may form a continuous linear arc over the entire length of the arc, or there may be a convex portion (or its vertices) that draws the arc at one or more points in the entire length of the arc. Instead, the apexes of the projections may be discontinuous and connected linearly to form a circular arc.

The outward convex portion and the inward convex portion may be convex portions, and the cross-sectional shape of the convex portion is not particularly limited. preferable. Incidentally, the cross-sectional shape of the outward convex portion or the inward convex portion refers to the cross-sectional shape of the arc drawn by the outward convex portion or the inward convex portion when cut along a plane orthogonal to the circumferential direction at each position.

In the case where the outward convex portion and the inward convex portion are convex portions protruding in the shape of a circular arc or an elliptical arc in cross-sectional shape, even if the angle or position of sandwiching the target cooking vessel changes slightly, the convex portion can contact the wall surface of the cooking container, and in particular, when the target cooking container has a brim that spreads outward on the upper end of the side wall, the inward convex part Since it can contact not only the outer peripheral surface of the side wall of the cooking container but also the lower surface of the brim-shaped portion, there is an advantage that the target cooking container can be gripped more stably. The cross-sectional shape of the outward protrusion and the cross-sectional shape of the inward protrusion may be the same or different. In addition, the cross-sectional shapes of the outward convex portion and the inward convex portion may be the same over the entire length of the outward convex portion or the inward convex portion that are linearly connected in a circular arc, or convex portions with different cross-sectional shapes may be mixed. can be It should be noted that an elliptical arc is included in the arc when arcs are drawn and connected linearly.

In the cooking container gripper according to the present invention, when A _U is the central angle of the arc drawn by the outward convex portion, and A _L is the central angle of the arc drawn by the inward convex portion, both A _U and A _L are 30 degrees to 30 degrees. It is preferably in the range of 120 degrees, more preferably in the range of 40 to 110 degrees. Even if one or both of A _U and A _L are _less than 30 degrees, it does not mean that the cooking container cannot be _gripped . Since the portion and the inward convex portion can contact the side wall of the cooking container over a wide range in the circumferential direction of the side wall of the cooking container, the cooking container can be gripped more stably. In addition, even if one or both of _AU and _AL exceed 120 degrees, there is no particular problem in gripping the cooking container, but the inner contact body having the outward convex portion and the inward convex portion This is not preferable because the length of the outer abutment body having the portion becomes long, and the operability as a cooking container gripper may be deteriorated.

In the cooking container gripper according to the present invention, where AU is the central angle of the arc drawn by the outward projection, and _AL is the central angle of the arc drawn by the _inward projection, the relationship _AU ≤ _AL is satisfied. It is preferable that there is, and it is more preferable that there is a relationship of _AU < _AL . Even if there is a relationship of _AU > _AL , it does not mean that the cooking container cannot be gripped. It is preferable that the length of the circular arc drawn by the contacting inward convex portion is longer than the length of the circular arc drawn by the outward convex portion, since the cooking vessel can be operated more stably.

Incidentally, when the radius of curvature of the arc drawn by the outward convex portion is R _U and the radius of curvature of the arc drawn by the inward convex portion is R _L , R _U and R _L are the horizontal cross-sectional shapes of the side walls of the cooking container to be gripped. may be appropriately set according to the radius of curvature in . Since the outward convex portion contacts the inner peripheral surface of the side wall of the cooking container, and the inward convex portion contacts the outer peripheral surface of the side wall of the cooking container, _RU and _RL are usually such that _RU < _RL . in a relationship. There is no particular limit to the absolute size of _RU and _RL , and _RU and _RL are infinite when the horizontal cross-sectional shape is a square cooking container instead of a circular one. can be

In the cooking container gripper of the present invention, an inner contact body having an outward projection and an outer contact body having an inward projection are arranged such that the outward projection and the inward projection are adjacent to each other and the contact between the two projections is located between the two projections. support means for relatively movably supporting between a gripping position in which the side wall of the cooking container, which is an object to be gripped, is gripped, and a standby position in which the outward convex portion and the inward convex portion are separated from each other; ing. Such support means only needs to be able to support the inner contact body and the outer contact body so as to be relatively movable between the holding position and the standby position, and there are no particular restrictions on the structure or mechanism. no.

However, in a preferred aspect of the cooking vessel gripper according to the present invention, the support means supports the inner contact body and the outer contact body so as to be relatively rotatable around a common rotation axis. have the means. When the support means is of this type, the inner abutment body having the outward protrusion can be relatively moved to abut against the inner peripheral surface of the side wall of the cooking vessel from the top of the cooking vessel. Therefore, even when the cooking container is a shallow pan, there is an advantage that the outward protrusion is less likely to come into contact with the food stored in the cooking container.

In another preferred aspect of the cooking vessel gripper according to the present invention, the support means includes means for supporting the inner contact body and the outer contact body so as to be able to move in parallel relative to each other. ing. In the case where the support means is of this type, the inner contact member can be brought into contact with the inner circumferential surface of the side wall of the cooking vessel simply by relatively moving the inner contact member toward the outer contact member in parallel. Movement of the inner or outer abutment body from the standby position to the gripping position becomes compact, and even when the cooking container is positioned in a space with limited space in the vertical direction, the cooking container can be opened from the gap. The advantage is that the gripper can be inserted to grip the cooking vessel.

The support means described above may be operated manually, or may be connected to an appropriate actuator and operated by power from an appropriate power source such as an electric motor, an electromagnet, or fluid pressure. When the support means is operated by power from an appropriate power source, the operation can be controlled by an appropriate electrical signal or the like. It can be incorporated as an element into a cooking appliance or cooking system comprising a cooking vessel gripper according to the invention.

The cooking container targeted by the cooking container gripper of the present invention has a portion sandwiched between an outward convex portion linearly extending in an arc and an inward convex portion linearly extending in an arc. Any container may be used, and there are basically no particular restrictions on its shape, structure, or size. In the case of , the depth of insertion of the outward convex portion of the inner abutment body that abuts against the inner wall of the pan into the pan may be shallow, which is particularly suitable. In addition, the cooking container to be gripped may be a cooking container having a shape in which the upper end of the side wall rises vertically. In the case of a cooking container that is in the cooking container, the inward convex portion of the outer abutment body can be gripped by contacting not only the outer peripheral surface of the side wall but also the lower outer peripheral surface of the brim. This is preferable because it enables more stable gripping.

According to the cooking container gripper of the present invention, the cooking container is gripped by being sandwiched between the outward projections linearly extending in an arc and the inward projections linearly extending in the same arc. can be stably gripped, and even if the cooking container is turned over or shaken in a greatly inclined state, the grip is not unstable. In addition, according to the cooking container gripper of the present invention, since the depth of insertion of the outward protrusion into the cooking container may be shallow, even when gripping a pot with a relatively shallow bottom, the outward protrusion and the inner abutment are not required. The body is less likely to come into contact with the food to be cooked in the pan, which is sanitary and less dirty.

The present invention will be described in detail below with reference to the drawings, but it is needless to say that the present invention is not limited to the drawings.

FIG. 1 is a front view showing an example of a cooking container gripper according to the present invention. In FIG. 1, 1 is a cooking container gripper, 2 is a first operating arm, 2g is a grip portion of the first operating arm 2, 3 is a second operating arm, and 3g is a gripping portion of the second operating arm 3. As shown in FIG. 4 is a lock nut, 6 is an upper jaw provided at the tip of the first operating arm 2, 7 is a lower jaw provided at the tip of the second operating arm 3, and 8 is an inner contact attached to the upper jaw 6. Body, 9 is an outer abutment attached to the lower jaw 7, 10 is a washer.

FIG. 2 is a plan view of the cooking vessel gripper 1 shown in FIG. 1, and the same members are given the same reference numerals. In FIG. 2, 5 is a truss screw, the shaft portion of which passes through the first operating arm 2, the washer 10, and the second operating arm 3, and the lock nut 4 is attached to the tip portion. Thereby, the first operating arm 2 and the second operating arm 3 are relatively rotatably supported with the axis of the truss screw 5 as the rotation axis. The means for supporting the first operating arm 2 and the second operating arm 3 so as to be relatively rotatable about the rotation axis is not limited to the combination of the truss screw 5 and the lock nut 4. Of course, other appropriate means capable of rotatably supporting may be used.

FIG. 3 is a right side view of the cooking vessel gripper 1 shown in FIG. 1, and the same members are given the same reference numerals. As can be seen in FIG. 3, the grip portion 2g of the first operating arm 2 and the grip portion 3g of the second operating arm 3 each have a bulge and are shaped to be easy to grip.

As shown in FIGS. 1 to 3, each of the inner contact member 8 and the outer contact member 9 is formed of a round bar that is bent into an arc shape. The contact body 8 is fixed to the upper jaw 6 positioned at the tip of the first operating arm 2, and the outer contact body 9 is fixed to the lower jaw 7 positioned at the tip of the second operating arm 3, respectively.

FIG. 4 is a partially enlarged cross-sectional view of a part of the cooking container gripper 1 cut along the line X-X' of FIG. For convenience, part of the upper jaw 6 is shown in dashed lines. As described above, in the cooking container gripper 1 of this example, the inner contact body 8 and the outer contact body 9 are both formed of circular rods bent in an arc shape. Both are circular as shown in FIG.

In the circular cross-section of the inner contact body 8 shown in FIG. , is an inward projection β that protrudes toward the inner contact member 8 positioned inside. In this example, since both the inner contact body 8 and the outer contact body 9 have circular cross sections, both the outward convex part α and the inward convex part β are convex parts that protrude in an arc shape in cross-sectional shape. become.

The members constituting the inner contact body 8 and the outer contact body 9 are not limited to round bars, and may be bars having an elliptical cross section, hollow tubes having a circular cross section, or hollow tubes having an elliptical cross section. It may be an empty tube. Furthermore, it may be composed of an elongated member to which a rod or tube having a semi-circular or semi-elliptical cross section is attached. In addition, the inner contact body 8 and the outer contact body 9 do not have to have a uniform shape and structure over the entire length. It's okay to be Furthermore, the inner contact body 8 and the outer contact body 9 do not necessarily have the same shape, structure, and material, and may be composed of members with different shapes, structures, and materials.

In any case, the outward convex portion α and the inward convex portion β may be convex portions that protrude in cross-sectional shape, and desirably, convex portions that protrude in the shape of a circular arc or an elliptical arc in cross-sectional shape. Incidentally, as will be described later, the cross-sectional shape is the cross-sectional shape when the outward convex portion α and the inward convex portion β, which are linearly connected by drawing a circular arc, are cut along a plane orthogonal to the circumferential direction of the circular arc drawn by each. means.

FIG. 5 is a view of the inner contact body ₈ as seen from the Z8 direction shown in FIG. As shown in FIG. 5, since the inner contact body 8 is arcuate, the outward projections α corresponding to the projections protruding toward the outer contact body 9 in each cross section of the inner contact body 8 also draw arcs. are connected linearly. L1 to L5 each represent a plane perpendicular to the circumferential direction of the arc drawn by the outward convex portion α at the position where each of them intersects with the outward convex portion α. The cut cross-section corresponds to the cross-section shown in FIG. The outward convex portion α exists as a convex portion protruding in a circular arc in cross-sectional shape.

6 is a view of the outer contact body ₉ as seen from the Z9 direction shown in FIG. 4, and corresponds to a plan view of the outer contact body 9. FIG. As shown in FIG. 6, since the outer contact member 9 is arc-shaped, the inward convex portion β corresponding to the convex portion that protrudes most toward the inner contact member 8 in each cross section of the outer contact member 9 is also arc-shaped. While drawing, they are connected in a line. In addition, P1 to P5 represent planes perpendicular to the circumferential direction of the arc drawn by the inward convex portion β at the positions where each of them intersects with the inward convex portion β. corresponds to the cross section shown in FIG. β exists as an arcuate projection in the cross-sectional shape.

5, _AL is the central angle of the arc drawn by the inward convex portion β, _RL is the radius of curvature of the arc drawn by the inward convex portion β, and in FIG. 6, _AU is the arc drawn by the outward convex portion α. and _RU is the radius of curvature of the arc drawn by the outward projection α. The central angle _AU of the outward convex portion α and the central angle _AL of the inward convex portion β are as long as the target cooking container can be gripped while being in contact with the inner or outer peripheral surface of the side wall of the cooking container. Any number of degrees may be acceptable, but both A _U and A _L are preferably within the range of 30 degrees to 120 degrees, and more preferably within the range of 40 degrees to 110 degrees. Moreover, from the viewpoint of more stably gripping the cooking container, _AU ≤ _AL is preferable, and _AU < _AL is more preferable.

Incidentally, the radius of curvature _{RU of the arc drawn by the outward convex portion α and the radius of curvature RL of} the arc drawn by the inward convex portion β may be appropriately set according to the diameter of the cooking container to be gripped. That is, the cooking container gripper 1 according to the present invention is normally configured such that the outward projection α is brought into contact with the inner peripheral surface of the cooking container side wall, and the inward projection β is brought into contact with the outer peripheral surface of the cooking container side wall. Since the side wall of the cooking container is held between αβ, the radius of curvature R _U of the arc drawn by the outward convex part α is equal to the thickness of the side wall of the cooking container. It is better to make it smaller than _L.

Next, using FIGS. 7 to 9, the usage state of the cooking vessel gripper 1 according to the present invention will be described.

FIG. 7 shows the cooking container gripper 1 in a standby position in which the distance between the first operation bowl 2 and the second operation bowl 3 is widened and the inner contact body 8 and the outer contact body 9 are separated from each other. showing. For convenience, only the inner abutment member 8 and the outer abutment member 9 are shown as cross-sectional views taken along line X-X' in FIG. M is a pan, which is a cooking vessel to be grasped, which has a relatively shallow bottom and has a brim t extending outward at the upper end of a side wall w.

8, the cooking vessel gripper 1 is brought closer to the pot M from the state shown in FIG. The inward convex portion β of the pot M is brought into contact with the outer peripheral surface of the side wall w of the pot M, and the outward convex portion α of the inner contact body 8 is brought into contact with the inner peripheral surface of the side wall w of the pot M to grip the pot M. state. In this state, the inner abutment body 8 and the outer abutment body 9 are such that the outward projection α and the inward projection β are close to each other, and the pot M is clamped with the side wall w of the pot M sandwiched between the two projections. It is in the gripping position to grip. In addition, since the inward convex portion β of the outer contact body 9 is a convex portion projecting in a circular arc shape in cross section, the apex of the inward convex portion β contacts the outer peripheral surface of the side wall w of the pan M. At the same time, another part of the inward projection β abuts on the lower surface of the brim-shaped portion t that spreads toward the outside of the pot M, so that the pot M can be stably gripped.

FIG. 9 is a top view of the cooking vessel gripper 1 in the state shown in FIG. 8, and for the sake of convenience, a part of the first operation bowl 2 and the second operation bowl 3 are omitted. As shown in FIG. 9, when the inner abutment body 8 and the outer abutment body 9 are in the gripping position, the outward convex part α and the inward convex part β, which are linearly connected in a circular arc, are formed on the side wall w of the pot M. It abuts linearly on the inner peripheral surface and the outer peripheral surface of the side wall w along the arc.

In this way, since the outward convex portion α and the inward convex portion β are convex portions that draw circular arcs and are linearly connected, the inner contact body 8 and the outer contact body 9 each have their own convex portions. Although the pot M is shallow in the depth direction, it contacts the side wall w of the pot M over a relatively wide range in the circumferential direction, so that the cooking vessel gripper 1 can grip the pot M stably. For this reason, for example, as indicated by an arrow in FIG. It is also possible to shake the pot M up to.

Moreover, when gripping the pan M, the cooking container gripper 1 is configured such that the outward convex portion α, which is linearly connected in an arc of the inner contacting body 8, is positioned extremely shallowly from the inner peripheral surface of the side wall w of the pan M. Since the pot is only brought into contact with the object to be cooked, even if the object to be cooked is stored in the pot M, there is little possibility that the inner contact member 8 or the outward protrusion α thereof will come into contact with the object to be cooked, which is extremely hygienic. target.

FIG. 10 is a view showing another example of the cooking container gripper according to the present invention, showing a modification of the outer contact body 9 and the inward convex portion β of the outer contact body 9. As shown in FIG. As shown in FIG. 10, in this example, the inward convex portion β is linearly connected by drawing an arc with a central angle _AL , but is not continuous over the entire arc, and is discontinuous and intermittent. It is different from the example described above in that it is targeted.

FIG. 11(A) is a slightly enlarged cross-sectional view of the outer abutment body 9 cut at the plane P3, P6, or P9 in FIG. As can be seen in FIG. 11A, the inward convex portion β exists as a convex portion having an arcuate cross-sectional shape at each position. FIG. 11B is a slightly enlarged view of the cross-sectional shape of the outer abutment body 9 cut at the plane P7 or P8 in FIG. 10, similarly. As can be seen in FIG. 11B, there is no projecting protrusion in the cross-sectional shape. The planes P6 to P9 are planes perpendicular to the circumferential direction of the outer contact member 9 or the inward convex portion β at each position, similarly to the plane P3 shown above.

In this way, the inward convex portion β does not need to exist continuously over the entire area of the arc it draws, and may exist intermittently. In the case where the inward convex portion β is intermittently connected linearly while drawing a circular arc, the outer abutment body 9 is formed by an amount corresponding to the absence of the material forming the inward convex portion β at the location where the inward convex portion β does not exist. has the advantage of being lighter. Although not shown, the above description of the outer contact body 9 and the inward convex portion β based on FIGS. This also applies to α.

FIG. 12 is a view showing still another example of the cooking container gripper according to the present invention, in which the inner contact body 8 and its outward projection α, and the outer contact body 9 and its inward projection are shown. β shows a modified example. As shown in FIG. 12, in this example, both the radius of curvature of the arc drawn by the outward protrusion α of the inner contact body 8 and the radius of curvature of the arc drawn by the inward protrusion β of the outer contact body 9 are It differs from the previous example in that it is infinite. That is, in this example, the outward convex portion α of the inner contact member 8 and the inward convex portion β of the outer contact member 9 are both circular arcs with an infinite radius of curvature, in other words, line segments. It is a convex portion that is drawn and connected in a linear fashion.

When the outward convex portion α of the inner contact member 8 and the inward convex portion β of the outer contact member 9 are connected linearly by drawing a line segment, a horizontal cross-sectional shape is formed between the two convex portions αβ. It is possible to pinch and grip the side walls of a rectangular cooking vessel such as a square or rectangle. In FIG. 12, the left and right outer sides are cross-sectional views of the outer contact body 9 and the inner contact body 8 cut at the planes P3 and L3, respectively. Since the body 8 and the outer abutment body 9 are formed of a round bar uniform in the longitudinal direction, the cross-sectional shape thereof is the same as that cut at the plane P3 or L3 regardless of the position of the cut. be. As shown in the figure, both the inward convex portion β and the outward convex portion α are convex portions protruding in an arc shape in cross-sectional shape.

FIG. 13 is a front partial cross-sectional view showing still another example of the cooking vessel gripper according to the present invention. In FIG. 13, 1 is a cooking container gripper, 6 is an upper jaw, 7 is a lower jaw, 8 is an inner contact body attached to the upper jaw 6, 9 is an outer contact body attached to the lower jaw 7, and α is an inner contact. The outward convex portion of the contact body 8 that draws a circular arc and continues linearly, and β is the inward convex portion of the outer contact body 9 that draws a circular arc and continues linearly. is.

Reference numeral 11 denotes a main body case of the cooking container gripper 1; 12, a lower cover covering the lower side of the main body case 11; is a sliding body slidably accommodated in the The tip of the body case 11 is provided with the aforementioned upper jaw 6 , and the tip of the sliding body 13 is provided with the aforementioned lower jaw 7 .

A lever 14 is rotatably connected to the lower cover 12 by a rotating shaft V at one end thereof. 15 ₁ and 15 ₂ are connecting rods, and the connecting rod 15 ₁ connects a turning fulcrum 16 ₁ provided inside the space S of the case body 11 and a turning fulcrum 16 ₂ provided on the lever 14 . The connecting rod _15-2 connects a turning fulcrum _16-2 provided _on the lever 14 and a turning fulcrum 16-3 provided at the rear end of the sliding body 13. As shown in FIG. Reference numeral H denotes a slide groove for a pivot point 162 provided on the lever 14. _The pivot point 162 is slidable within the slide groove H as indicated by the _two -way arrow in the figure. It is attached to the lever 14 . A spring 17 is arranged between the inside of the space S of the case body 11 and the rear end of the sliding member 13, and applies a tension to the sliding member ₁₃ to pull it back toward the rotation fulcrum 161. .

At the position shown in FIG. 13, the outward convex portion α and the inward convex portion β are separated from each other, and the inner contact body 8 and the outer contact body 9 are arranged such that the outward convex portion α and the inward convex portion β are separated from each other. It is in a separate standby position. In this state, the cooking container gripper 1 is brought close to a cooking container (not shown) to be gripped, and after the inner abutment body 8 is positioned inside the side wall of the cooking container, the lever 14 is moved toward the main body case 11 . , the pivot point ₁₆₂ attached to the lever ₁₄ is also pushed by the connecting rod 151 and slides in the slide groove H in the direction of the rotation axis V. As it moves, it pushes the sliding body 13 forward, that is, toward the inner contact body ₈ via the connecting rod 152 . As a result, the inward convex portion β of the outer abutment body 9 attached to the sliding body 13 comes close to the outward convex portion α of the inner abutment body 8 attached to the upper jaw 6. The cooking container is gripped with the side wall of the cooking container to be gripped sandwiched therebetween.

Thus, in the cooking container gripper 1 of this example, relative movement between the gripping position and the standby position of the inner contact body 8 and the outer contact body 9 is The support means, which is performed by relative parallel movement with respect to the abutment body 8 and supports the inner abutment body 8 and the outer abutment body 9 so as to be relatively movable between the holding position and the standby position, It is means for supporting the inner abutment body and the outer abutment body so as to be able to move in parallel relative to each other. When the supporting means for supporting the inner contacting body 8 and the outer contacting body 9 so as to be relatively movable between the gripping position and the standby position is a means for supporting them so as to be relatively movable in parallel. When moving from the standby position to the gripping position, the inner contact body 8 and/or the outer contact body 9 do not need to be largely rotated, so even in a place where the space between the upper and lower sides is limited, the target cooking can be performed. It is convenient because the container can be gripped.

As described above, according to the cooking container gripper of the present invention, the side wall of the cooking container is gripped between the outward convex portion and the inward convex portion, which are linearly connected in a circular arc. The range of contact with the side wall is large, and the cooking container can be stably gripped. In addition, since the cooking container can be gripped without inserting the distal end portion of the gripper deeply into the cooking container in the depth direction, it is possible to grip the cooking container satisfactorily in terms of hygiene. The industrial applicability of the cooking vessel gripper of the present invention is great.
