[1 First embodiment]
[1-1 Configuration of holding jig 1]
The holding jig 1 according to the first embodiment is configured to be able to hold the object M to be held. Although the object to be held M is not particularly limited, the container 101 is preferable. When the object to be held M is a container 101, the container 101 has a main body 102 with an open upper side and a flange 103 extending outward on the upper end (upper edge) side of the main body 102. I can give an example. In the container 101, an opening 104 of the main body 102 is formed inside the flange 103.

The holding jig 1 has an insertion part 2 through which the object M to be held is inserted, and a support part 3 that supports the object M on the outside of the insertion part 2. The holding jig 1 has a holding structure 4 that holds an object M to be held. The holding structure 4 has a structure including a support part 3 and an insertion part 2, and has two states: the object to be held M is inserted into the insertion part 2, and a predetermined part of the object to be held M is supported by the support part 3. It has a structure that allows

(Support part 3)
The support portion 3 is specified as a portion that supports the object M to be held. For example, in the examples shown in FIGS. 1, 2A, and 2B, the object M to be held is supported by a structural part in which the bridge members 5 are arranged in an annular manner, as will be described later. It is specified as an annular structural part in which the elements are arranged in a ring. The support portion 3 is formed outside the insertion portion 2 .

(Insertion part 2)
The insertion part 2 is defined as a space 106 around which the support part 3 is formed, and through which the object to be held M passes. In the example shown in FIG. 1, the space is specified as a space inside an annular structural portion in which the bridge members 5 are arranged annularly. The insertion portion 2 is specified as a space 106 through which the object to be held M passes inside the support portion 3 when the object to be held M is supported by the support portion 3 .

(Base plate 6)
The holding jig 1 is provided with a base plate 6 that supports the bridge member 5 from below. The base plate 6 is provided with a through hole 7. In the example of FIG. 1 , the through hole 7 is formed to penetrate the base plate 6 in the thickness direction of the base plate 6 and to allow the object M to be held to pass below the insertion portion 2 . The material of the base plate 6 is not particularly limited, such as metal, plastic, wood, glass, ceramic, etc., but from the viewpoint of excellent strength, the base plate 6 is preferably made of metal. In the examples shown in FIGS. 1, 2A, and 2B, the external contour of the base plate 6 has a tongue-like shape, but this is just an example, and it may have other shapes such as a rectangular shape or a circular shape. Good too. Further, although the base plate 6 has been described using an example in which the through hole 7 is provided, the shape of the base plate 6 is not limited to this. For example, the base plate 6 may be formed in the shape of a cut from the outside to the inside so that the object to be held M can pass therethrough, or it may have a structure other than this. Further, in this specification, the “direction toward the inside of the through hole 7” is an example of the direction toward the inside of the insertion portion 2, and the “direction toward the outside of the through hole 7” refers to the direction toward the outside of the insertion portion 2. This is an example of the direction toward.

(piece member 5)
In the holding jig 1, the plurality of piece members 5 are arranged in an annular shape. Here, "arranged in an annular manner" means arranged so as to surround the reference position when the thickness direction of the base plate 6 is taken as the line of sight direction and the center position CT of the through hole 7 is taken as the reference position. Indicates the current state. When arranged in an annular shape, if the direction away from the reference position (the direction that spreads outward from the reference position along the plane normal to the thickness direction of the base plate 6) is the line of sight, then the adjacent plural This includes cases in which the pieces 5 overlap, cases in which at least some adjacent pieces 5 are separated, and cases in which at least some adjacent pieces 5 are in contact with each other. shall be taken as a thing.

(Shape and layout of bridge member 5)
Although the shape of the bridge members 5 is not particularly limited, in the example of FIG. shape). The shape of the bridge member 5 shown in FIG. 2A ranges from a sector (large sector) to a concentric sector ( It is shaped like a small fan-shaped part. In this example, the bridge member 5 has a side surface (inner surface 12) closer to the insertion section 2, a side surface (outer surface 13) farther from the insertion section 2, and a side surface (lateral surface) facing the adjacent bridge member 5. 14), the inner surface 12 has a concave curved surface shape (in the example of FIG. 2A, an arcuate surface shape), the outer surface 13 has a convex curved surface shape (in the example of FIG. 2A, a circular arc surface shape), The lateral side surface 14 is formed into a flat surface shape.

In the example of FIG. 2A, the plurality of bridge members 5 are formed in roughly the same shape, and the layout of the plurality of bridge members 5 is arranged in a circular shape as a whole. However, this is just an example, and for example, the layout of the plurality of bridge members 5 may have a shape close to a non-circular shape, such as a rectangle.

In FIG. 2A, the position of the bridge member 5 is the state in which the bridge member 5 is displaced in the direction toward the inside of the through hole 7 (inwardly displaced state). In the inwardly displaced state, the lateral side surfaces 14 of adjacent bridge members 5 are in contact with each other. The tapered shape of the bridge member 5 restricts the displacement of the movable bridge member 8 further inward from the position in the inwardly displaced state.

(Movable piece member 8)
At least some of the plurality of bridge members 5 are movable bridge members 8. The movable piece member 8 is disposed so as to be displaceable in at least one of a direction toward the inside of the through hole 7 and a direction toward the outside of the through hole 7 in a plan view of the base plate 6. This is the bridge member 5 (in a non-fixed state). In the example of FIG. 2A, all of the plurality of bridge members 5 are movable bridge members 8. Furthermore, in this example, the movable piece member 8 is movable in either direction of the direction toward the inside of the through hole 7 or the direction toward the outside of the through hole 7 .

The movable piece member 8 is movable in the surface direction of the base plate 6. Note that being able to move in the plane direction of the base plate 6 means that the movable piece member 8 can not only move along the plane direction, but also move in a direction slightly different from the plane direction. It shall be a concept that includes

(Stress loading mechanism 9)
The holding jig 1 has a stress loading mechanism 9. The stress loading mechanism 9 applies stress to the movable bridge member 8 in accordance with the displacement of the movable bridge member 8. For example, the stress loading mechanism 9 is composed of an elastic member 10. In the example of FIG. 2, the elastic member 10 is formed in an annular shape and is arranged to surround a plurality of piece members 5 arranged in an annular manner. The direction of expansion and contraction of the elastic member 10 is along the groove 11 of the bridge member 5. A groove 11 extending along the outer surface 13 is formed in the outer surface 13 of the bridge member 5, and the position of the groove 11 is generally the same for all of the plurality of bridge members 5. The elastic member 10 is arranged so as to pass inside each groove 11 of the plurality of groove 11 members. In the holding jig 1, in a natural state in which the object M to be held is not placed, the movable piece members 8 (all the piece members 5 in FIG. 2A) move toward the inside of the through hole 7 due to the restoring force of the elastic member 10. It is in a state where it is displaced (inwardly displaced state).

Note that in this specification, the state in which the movable bridge member 8 is displaced toward the outside of the through hole 7 is referred to as the outer displacement state, and the state in which the movable bridge member 8 is displaced toward the inside of the through hole 7 is referred to as an outer displacement state. This is called the inner displacement state.

(Elastic member 10)
The elastic member 10 is not particularly limited, and examples thereof include rubber and springs, but it is easy to specify the general directionality of the restoring force, and it is possible to apply stress to the bridge member 5 in a specific direction. A spring is preferable from the viewpoint of easily forming a state in which this occurs. The material of the elastic member 10 is not particularly limited, but from the viewpoint of strength, it is preferably metal.

(Displacement control of movable piece member 8 by stress loading mechanism 9)
The stress loading mechanism 9 may control the displacement of the movable bridge member 8 (the displacement of all the bridge members 5 in the first embodiment) as shown below. When the object to be held M is passed through the through hole 7, the object to be held M also passes through the insertion portion 2. When the size of the held object M (size in plan view) exceeds the insertion portion 2 in the inwardly displaced state, the held object M exerts a pressing force against the plurality of bridge members 5 in the direction toward the outside of the through hole 7. , and the bridge member 5 is displaced toward the outside of the through hole 7, as shown by broken lines in FIGS. 3A and 3B. At this time, the elastic member 10 expands (generates a restoring force), and the piece is moved from the elastic member 10 in accordance with the displacement (conditions such as the magnitude of displacement) of the movable piece member 8 in the direction toward the outside of the through hole 7. A restoring force is applied to the member 5. In the case of FIGS. 3A and 3B, the elastic member 10 tightens the support portion 3 from the outer surface 13 of the bridge member 5. When the object M to be held is the container 101 and the flange portion 103 as described above is present on the container 101, a state is formed in which the flange portion 103 is latched onto the upper surface side of the piece member 5, and the object to be held is A state in which M is supported by the piece member 5 of the holding jig 1 (a state in which it is supported by the support portion 3) is formed.

When the held object M is removed from the support section 3, the state in which the held object M is supported by the piece member 5 of the holding jig 1 is released. At this time, a case is formed in which the pressing force is removed, and the balance between the pressing force and restoring force (stress) is disrupted. That is, when the pressing force is removed, the stress loading mechanism 9 displaces the bridge member 5 in the direction toward the inside of the through hole 7 based on the action of the stress (restoring force) applied to the bridge member 5. .

[1-2 Action and effect]
According to the first embodiment, the size of the insertion portion 2 changes with the displacement of the bridge member 5, and the size of the support portion 3 can be changed. Even for a plurality of types of containers 101 of different sizes as objects to be held M, the container 101 and the upper surface of the piece member 5 can be brought into contact with the same holding jig 1, and the container 101 can be supported by the support section 3.

Furthermore, according to the holding jig 1 of the first embodiment, the sizes of the insertion part 2 and the support part 3 can be changed as the bridge member 5 is displaced, so that the size and shape of the main body part 102 of the container 101 can be changed. It is possible to deal with cases where there is fluctuation (shaking).

Next, a modification of the first embodiment will be described. Note that the modifications described below may be combined with each other as long as they do not contradict each other.

[1-3 Modification example]
(Modification 1)
In the holding jig 1 according to the first embodiment, as shown in FIGS. 4A, 4B, 4C, and 4D, the shape of the bridge member 5 is oriented from the top surface to the bottom surface (bottom surface) of the bridge member 5. When the direction is the line of sight direction, it may have a shape different from the "shape obtained by removing the fan shape from the fan shape" as shown in FIG. 2A and the like. This embodiment will be referred to as modification 1 of the first embodiment. 4A, FIG. 4B, FIG. 4C, and FIG. 4D are perspective views showing an example of the piece member 5 used in an example of the holding jig 110 according to the first modification of the first embodiment.

In FIGS. 4A, 4B, and 4C, the bridge member 5 has an inner surface 12, an outer surface 13, and a lateral surface 14, and the inner surface 12 is formed in a convex arc shape or a planar shape, respectively. .

In FIG. 4D, the lateral side surface 14 of the bridge member 5 is connected to the inner side surface 12, and the inner side surface 12 forms a convexly curved surface.

(Modification 2)
In the holding jig 1 according to the first embodiment, the plurality of bridge members 5 have the same shape and size in the example of FIG. 2A, but the shape and size of the plurality of bridge members 5 are the same. It doesn't have to be. For example, as shown in FIG. 5, when a combination of two bridge members 5 (a first bridge member 5a and a second bridge member 5b) is selected, the sizes of the two bridge members 5 are different. Plural types of bridge members 5 may be used so that combinations can be selected.

(Modification 3)
In the holding jig 1 according to the second modification of the first embodiment, in the example of the arrangement of the bridge members 5 shown in FIG. A case where the bridge member 5 is different from the bridge member 5 is illustrated. When a plurality of types of bridge members 5 are used, the arrangement of the bridge members 5 is not limited to the example shown in the second modification of the first embodiment. For example, as shown in FIG. 6, with the piece member 5 disposed at a predetermined position as a reference (selected piece member 5c), a piece that is away from the selected piece member 5c as a reference along the alignment direction A of the piece members 5 is The size of the piece member 5 becomes smaller as the member 5 increases, and when the size of the piece member 5 is reduced to a predetermined size, the piece member 5 further becomes further away from the selected piece member 5c, which has become smaller to the predetermined size. The sizes of the bridge members 5 may be approximately equal in the directions. Note that the alignment direction A (alignment direction) is the direction in which the line extends, assuming a line formed by connecting the center of the piece member 5 and the center of the piece member 5 adjacent to the piece member 5. show.

(Modification 4)
In the holding jig 1 according to the first embodiment, when the stress loading mechanism 9 includes the elastic member 10, the stress loading mechanism 9 is attached to each of the bridge members 5, as shown in FIGS. 7A and 7B. A plurality of elastic members 10 may be provided so that stress can be applied individually to the elastic members 10. Such a configuration will be referred to as modification 4 of the first embodiment. In the example shown in FIGS. 7A and 7B, the stress loading mechanism 9 includes a plurality of elastic members 10, and each elastic member 10 is configured to apply stress to each piece member 5. 7A and 7B are a plan view and a cross-sectional view showing an example of a holding jig 1 according to a fourth modification of the first embodiment. Note that when stress is applied individually to each of the bridge members 5 referred to herein, stress is applied only to the bridge member 5 (target bridge member 5) to which the elastic member 10 directly applies stress. The present invention is not limited to the case in which the stress from the elastic member 10 is applied to another piece member 5 via the target piece member 5.

(Stress loading mechanism 9)
In the example of the holding jig 1 shown in FIGS. 7A and 7B, the stress loading mechanism 9 includes a plurality of elastic members 10 and a receiving member 15.

(Receiving material 15)
The receiving member 15 forms a wall portion 16 on the outside of the bridge member 5. The receiving material 15 may be placed on the base plate 6. The receiving member 15 is in direct or indirect contact with (or has one end fixed to) one of the two ends of the elastic member 10 that are separated from each other in the direction of expansion and contraction of the elastic member 10 . This is a member that is subjected to restoring force due to expansion and contraction.

(Elastic member 10)
The elastic member 10 is arranged between the bridge member 5 (particularly the movable bridge member 8) and the wall portion 16 of the receiving member 15. As the elastic member 10, a spring or the like may be used as described in the first embodiment. In the example shown in FIGS. 7A and 7B, when the movable bridge member 8 is displaced in the direction toward the outside of the through hole 7, a restoring force is generated in the elastic member 10.

(Scope regulation structure 17)

The step 25 is formed to cross the upper surface of the bridge member 5 at a predetermined position between the upper end of the inner surface 12 and the upper end of the outer surface 13. The upper surface of the bridge member 5 is divided into a first portion 26 that is closer to the insertion portion 2 than the step 25 (closer to the inner surface 12) and a first portion 26 that is farther from the insertion portion 2 than the step 25 (outer). When the step 25 is divided into a second part 27 (the one closer to the side surface 13), the step 25 is arranged such that the first part 26 is located above the second part 27 in the vertical direction (the one closer to the insertion part 2). The upper surface of the bridge member 5 is formed so that the position of the upper surface of the bridge member 5 becomes higher.

Furthermore, in FIG. 11C, the lower surface of the covering plate 23 is located lower than the first portion 26 in the vertical direction.

(Scope regulation structure 17)
In the holding jig 1 as shown in FIG. 11C, the combination of the step 25 and the exposure hole 24 of the covering plate 23 can serve as the range regulating structure 17. The range regulating structure 17 is a structure that regulates the displacement range of the movable piece member 8, as described in the fourth modification of the first embodiment. In the holding jig 1 as shown in FIG. 11C, the lower surface of the covering plate 23 is located lower than the first portion 26 in the vertical direction. When the movable bridge member 8 is displaced outwardly, the position of the step 25 approaches the exposure hole 24 of the cover plate 23, and the movable bridge member 8 moves toward the position where the lower step 25 contacts the exposure hole 24 of the cover plate 23. Displacement toward the outside due to this is regulated. In FIG. 11C, the combination of the step 25 and the covering plate 23 restricts the displacement range of the movable bridge member 8 to within the range of the exposure hole 24. In FIG. The specific displacement range of the movable piece member 8 is determined according to the distance between the step 25 provided in the movable piece member 8 of the piece member 5 and the exposure hole 24.

(Modification 9)
In the holding jig 1 according to the first embodiment, a length changing mechanism 28 may be provided as shown in FIGS. 12A and 12B. Such a configuration will be referred to as modification 9 of the first embodiment. 12A and 12B are a plan view and a sectional view showing an example of the holding jig 1 according to Modification 8 of the first embodiment.

(Length changing mechanism 28)
The length changing mechanism 28 changes the length of the bridge member 5 and the length of the bridge member 5 along the direction A in a plan view of the bridge member 5. Here, the alignment direction A of the piece members 5 is the direction in which the line extends, assuming a line formed by connecting the center of the piece member 5 and the center of the piece member 5 adjacent to the piece member 5. shall be indicated.

The length changing mechanism 28 changes the length of the bridge member 5 along the alignment direction A according to the distance between the bridge member 5 and the adjacent bridge member 5. In the example shown in FIGS. 12A and 12B, the length changing mechanism 28 has a structure in which an elastic member 10 is provided in a hole 30 provided in a partial piece 29, which will be described later.

(Part 29)
In the example of FIGS. 12A and 12B, at least a portion of the bridge member 5 has a plurality of partial pieces 29. The bridge member 5 provided with a length changing mechanism 28 has a plurality of partial pieces 29 . The partial piece 29 indicates a portion constituting the bridge member 5. In the example of FIGS. 12A and 12B, the bridge member 5 includes two partial pieces 29.

(Elastic member 10 provided in length changing mechanism 28)
In the bridge member 5 provided with the length changing mechanism 28, holes 30 are formed in the respective partial pieces 29 so as to face each other, and the elastic members 10 are provided in the holes 30. This elastic member 10 constitutes a length changing mechanism 28. The elastic member 10 is connected to the inner surface of the hole 30. When the bridge member 5 provided with the length changing mechanism 28 is in an inwardly displaced state, the elastic member 10 is in a contracted state, and as the bridge member 5 is displaced outwardly, the interval between the partial pieces 29 is reduced. The restoring force of the elastic member 10 acts to spread it. Then, by changing the interval between adjacent partial pieces 29, the length of the piece member 5 along the alignment direction A of the piece member 5 is changed.

In the example of FIGS. 12A and 12B, when the length changing mechanism 28 displaces the bridge member 5 in the direction toward the inside of the through hole 7, the restoring force of the elastic member 10 is applied to the partial piece 29. Note that the stress loading function is applied to the bridge member 5 when the bridge member 5 is displaced in the direction toward the outside of the through hole 7 (when the object M to be held is passed through the insertion section 2 and supported by the support section 3). , a pressing force is applied from the object to be held M, and a restoring force is applied from the elastic member 10. When displacing the bridge member 5 in the direction toward the outside of the through hole 7, the elastic member 10 of the length changing mechanism 28 adjusts the distance between adjacent pieces 29 due to the restoring force applied to the pieces 29. It can be expanded. When the object to be held M is removed, the bridge member 5 is displaced in the direction toward the inside of the through hole 7 due to the restoring force from the elastic member 10. Accordingly, the restoring force of the elastic member 10 is applied to the partial piece 29 (the elastic member 10 contracts).

In the example of FIGS. 12A and 12B, at least a part of the bridge member 5 includes a plurality of partial pieces 29 and a length changing mechanism 28, so that the bridge member 5 is moved in the direction toward the outside of the through hole 7. When the object to be held M is moved to (when the object M is passed through the insertion part 2 and supported by the support part 3), the interval between the adjacent piece members 5 can be reduced. This effect can be further enhanced when the bridge member 5 includes three or more partial pieces 29 and includes the length changing mechanism 28.

(Other examples of the number of partial pieces 29)
In the example of FIGS. 12A and 12B, at least a portion of the bridge member 5 includes two partial pieces 29, but as shown in FIGS. 13A and 13B, at least a portion of the bridge member 5 includes three partial pieces 29. The above partial piece 29 may also be provided. In FIGS. 13A and 13B, a case is illustrated in which each movable piece member 8 includes three partial pieces 29.
