Description

[Technical field]

[0001] The present invention relates to a connecting part for connecting a plurality of components. [Background technology]

[0002] In humanoid toys, etc., connecting parts are used to connect multiple parts to the movable parts. For example, Patent Document 1 discloses a humanoid toy that does not require assembly, in which a spherical connecting part with continuous unevenness on the entire outer circumference is covered by insert molding. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 09-313742 Summary of the Invention [Problem to be solved by the invention]

[0004] The spherical connecting part of Patent Document 1 is spherical, so even if the connecting part is angled, it will easily return to its original shape, which makes it difficult to display the humanoid toy in an angled pose and maintain it. Also, when the user assembles the connecting parts themselves, it can be difficult to achieve an angled pose at the connecting part if the assembly is not done properly.

[0005] The present invention provides a technique for forming connected parts capable of maintaining the relative positional relationship between connected parts. [Means for solving the problem]

[0006] A first aspect of the present invention is a connecting part comprising an axle part and a bearing part, wherein the axle part is an integral structure having an axle part, a first engagement part provided toward the axle part, and a pair of arms supporting the axle part from both ends of the axle part, all formed from the same first resin material, and the bearing part is a tubular part formed from a second resin material having a hardness different from that of the first resin material, the tubular part being provided on the outside of the axle part and positioned at both ends sandwiched between the pair of arms, the tubular part having at least one second engagement part formed on its outer surface with which the first engagement part can engage.

[0007] The first engagement portion may be a claw portion, and the second engagement portion may be a groove portion.

[0008] The second engagement portion may be a groove portion parallel to the axial direction of the shaft portion, and the first engagement portion may be a claw portion having a linear tip parallel to the axial direction of the shaft portion.

[0009] In addition, the bearing part may have a movable range limiting portion formed of the second resin material that abuts against the arm portion to limit the relative rotation range between the shaft part and the bearing part around the shaft portion as an axis, and the cylindrical portion and the movable range limiting portion may be of an integral structure.

[0010] The first resin material may have a harder hardness than the second resin material.

[0011] In addition, the shaft parts may include a first part and a second part formed from the first resin material, and the bearing parts may have an integral structure having a first cylindrical portion that is the cylindrical portion corresponding to the shaft portion of the first part and a second cylindrical portion that is the cylindrical portion corresponding to the shaft portion of the second part, both formed from the same second resin material.

[0012] The shaft portion of the first part and the shaft portion of the second part may have axial directions parallel to each other.

[0013] In addition, the shaft parts may include a first part, an intermediate part, and a second part formed of the first resin material, and the bearing parts may include a first bearing part and a second bearing part, the first bearing part being an integral structure having a tubular portion corresponding to the shaft portion of the first part and a tubular portion corresponding to the shaft portion of the intermediate part, both formed of the same second resin material, and the second bearing part being an integral structure having a tubular portion corresponding to the shaft portion of the intermediate part and a tubular portion corresponding to the shaft portion of the second part, both formed of the same second resin material.

[0014] Moreover, the shaft portion of the first part, the shaft portion of the intermediate part, and the shaft portion of the second part may have axial directions parallel to one another.

[0015] A second aspect of the present invention is an injection kit comprising a connecting part of the first aspect which is one of the assembly parts, the connecting part having the first engagement portion engaged with the second engagement portion, and a runner to which the shaft part and / or the bearing part constituting the connecting part are connected.

[0016] A third aspect of the present invention is a humanoid toy in which the connecting parts according to the first aspect are used in the joints. Effect of the Invention

[0017] According to the present invention, it is possible to provide connected parts that are capable of maintaining the relative positional relationship between connected parts. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] 1 is a diagram showing the front outline and arrangement of connecting parts of a humanoid toy 2 in an upright position as an example of this embodiment. The outline is shown by a dashed line.

[0020] The humanoid toy 2 is a toy that reproduces a character originally from a manga, anime, special effects movie, game, novel, etc. as a three-dimensional object. The humanoid toy 2 of this embodiment has a design imitating a humanoid robot weapon equipped with a weapon item 4. The humanoid toy 2 is a so-called plastic model, and is a toy that the user cuts out parts from an injection kit and assembles to complete it.

[0021] The humanoid toy 2 has multiple movable parts, and uses connecting parts 6 at one or multiple locations of the movable parts to connect the multiple parts in a manner that allows the relative angle between them to be variable. Where and how many connecting parts 6 are used can be appropriately determined according to the design of the humanoid toy 2. In the example of FIG. 1, they are used as part of the built-in frames of the elbow joints of both arms, the knee joints of both legs, and the six weapon items 4. Of course, depending on the design of the humanoid toy 2, the connecting parts 6 may be parts that are visible from the outside.

[0022] FIG. 2 is a diagram showing an example of an injection kit 8 of a connecting part 6. The injection kit 8 is included in the package of the humanoid toy 2. In the injection kit 8, multiple connecting parts 6 are integrally molded using gates and runners. The injection kit 8 is produced in one or multiple molding processes using multiple types of synthetic resin materials that make up the connecting parts 6.

[0023] Fig. 3 is a front view of the connecting part 6. Fig. 4 is a top view of the connecting part 6. Fig. 5 is a bottom view of the connecting part 6. The three orthogonal axes in the drawings including Figs. 3 to 5 are coordinate axes for indicating directions, and the origin of the coordinates is meaningless. The front direction is the positive Z-axis direction, the right direction as viewed from the positive front direction is the positive X-axis direction, and the upward direction as viewed from the positive front direction is the positive Y-axis direction.

[0024] The connecting part 6 is a movable part that connects a total of three connection target parts 9 (9a, 9b, ...) in such a way that the relative posture and relative position can be changed. The connecting part 6 is configured by connecting two shaft parts 10 (first shaft part 10a, second shaft part 10b), two bearing parts 20 (first bearing part 20a, second bearing part 20b), and one intermediate part 30 in series. The connection order, from the left when facing the front, is the first shaft part 10a, the first bearing part 20a, the intermediate part 30, the second bearing part 20b, and the second shaft part 10b.

[0025] The first axis part 10a and the second axis part 10b of the axis part 10 are components of the same shape but differ in their connecting positions and orientations. The first bearing part 20a and the second bearing part 20b, which are the bearing parts 20, are parts having the same shape but are connected at different positions and in different orientations.

[0026] The connecting part 6 is designed so that the axis of the first shaft part 10a and the first bearing part 20a and the axis of the second bearing part 20b and the second shaft part 10b are parallel to each other. Of course, a design in which these axes intersect is also possible.

[0027] FIG. 6 is a perspective view of the shaft part 10. As shown in FIG. The shaft part 10 is an integral structure having a shaft portion 11, a claw portion 13, an arm portion 15, and an attachment portion 17. The shaft part 10 is made of the same first resin material (for example, ABS (acrylonitrile butadiene styrene resin): a resin having a higher hardness than the second resin material) and is molded in the first injection when manufacturing the injection kit 8.

[0028] The attachment portion 17 is a portion for attaching a component to be connected to the shaft part 10 (in the example of FIG. 3, the first connection target part 9a for the first shaft part 10a, and the second connection target part 9b for the second shaft part 10b). In the example of FIG. 6, the attachment portion 17 is illustrated as having a hole in a plate-like portion, but may have other shapes.

[0029] A pair of arms 15 extend to the right from both the front and back ends of the mounting portion 17, and a cylindrical shaft portion 11 is formed between the pair of arms 15 in the front-to-rear direction (Z-axis direction).

[0030] A claw portion 13 is provided on the side surface of the attachment portion 17 facing the shaft portion 11 with its tip facing the shaft portion 11 .

[0031] The claw portion 13 is a first engagement portion provided toward the shaft portion 11, and has a linear tip that is parallel to the axial direction of the shaft portion 11. Specifically, the tip shape of the claw portion 13 is wedge-shaped tapering toward the shaft portion 11 when viewed in the XY cross section, and forms a linear shape that is parallel (or approximately parallel within a range that includes error) along the Z axis direction. Between the shaft portion 11 and the claw portion 13, there is a space in which the thick portion of the tube related to the cylindrical portion 21 of the bearing part 20 is positioned.

[0032] In addition, a movable range limiting surface 16 is formed on the right side of the arm portion 15, which abuts against the side in the X-axis direction of a first movable range limiting portion 26 (see Figure 7) of the bearing part 20 described later, and serves to limit the movable range of axial rotation between the shaft part 10 and the bearing part 20 (specifically, the range in which the mounting portion 17 of the shaft part 10 swings upward relative to the shaft portion 11).

[0033] FIG. 7 is a perspective view of the bearing part 20. As shown in FIG. The bearing part 20 is an integral structure having two cylindrical portions 21 (21a, 21b), groove portions 22 (22a, 22b, 22c), a large diameter portion 23, a first movable range limiting portion 26, and a second movable range limiting portion 27. The bearing part 20 is made of a second resin material having a different hardness from the first resin material (for example, PP (polypropylene) resin: a resin having a lower hardness than the first resin material), and is molded by a second injection when manufacturing the injection kit 8.

[0034] The two tubular parts 21 (first tubular part 21a, second tubular part 21b) are substantially cylindrical bodies provided on the outside of the shaft part 11 of the shaft part 10, with both ends sandwiched between the pair of arm parts 15. A plurality of grooves 22 (22a, 22b, ...) with which the claw parts 13 of the shaft part 10 can be engaged are formed on the outer circumferential surface of the tubular part 21 (first tubular part 21a, second tubular part 21b). The cylinder axes of the two tubular parts 21 are set parallel to each other.

[0035] The groove portion 22 is a second engagement portion with which the claw portion 13 (first engagement portion) can be engaged, and is provided parallel to the axial direction of the shaft portion 11 (including approximately parallel within a range that includes an error). Specifically, a movable range Am of the same radius is set on the outer circumferential surface of the cylindrical portion 21, and a V-shaped groove portion 22 is formed in the movable range Am. Specifically, a total of three groove portions 22 (22a, 22b, 22c) are formed at both ends of the movable range Am and in the middle. Among the groove portions 22, the groove portion 22c that is engaged with the claw portion 13 in the injection kit 8 state (see FIG. 2) has one of its side surfaces that forms a groove and also serves as a flat surface that constitutes the large diameter portion 23 that is larger than the radius of the movable range Am.

[0036] The first movable range limiting portion 26 is a protrusion formed from an intermediate position between the two cylindrical portions 21 toward the cylindrical axis direction (front-rear direction: Z-axis direction) of the cylindrical portions 21. The first movable range limiting portion 26 abuts against the arm portion 15 of the shaft part 10 to limit the relative rotation range between the shaft part 10 and the bearing part 20 about the shaft portion 11 as the axis center. Specifically, it serves to limit the swinging movement of the attachment portion 17 upward (positive direction of the Y-axis) relative to the shaft portion 11.

[0037] The second movable range limiting portion 27 is a convex portion formed downward (in the negative Y-axis direction) from the lower surface of the bearing part 20. The left and right side surfaces of the second movable range limiting portion 27 come into contact with the abdomen (lower surface) of the claw portion 13 of the shaft part 10, thereby limiting the downward swinging movement of the attachment portion 17 relative to the shaft portion 11.

[0038] The first cylindrical portion 21a of the first bearing part 20a is a portion corresponding to the shaft portion 11 of the first shaft part 10a. The second cylindrical portion 21b of the first bearing part 20a is a portion corresponding to the first shaft portion 31a of the intermediate part 30 (see FIG. 8). Moreover, the first cylindrical portion 21a of the second bearing part 20b is a portion corresponding to the shaft portion 11 of the second shaft part 10b. The second cylindrical portion 21b of the second bearing part 20b is a portion corresponding to the second shaft portion 31b of the intermediate part 30.

[0039] FIG. 8 is a perspective view of the intermediate part 30. The intermediate part 30 is a part that is connected to the first bearing part 20a and the second bearing part 20b, and is used to attach the third connection target part 9c (see FIG. 3). The intermediate part 30 is an integral structure having two shaft portions 31 (31a, 31b), two claw portions 33 (33a, 33b), an arm portion 35, and an attachment portion 37. The intermediate part 30 is made of the same first resin material (for example, ABS resin: harder than the second resin material), and is molded in the first injection when manufacturing the injection kit 8.

[0040] The attachment portion 37 is a portion for attaching a part (the third connection target part 9c in the example of FIG. 3) to be connected to the intermediate part 30. Here, the attachment portion 37 is illustrated as a hollow box body that protrudes upward from the upper surface of the plate portion, but may have other shapes. A pair of arms 35 extend from the ends of the front side (positive Z-axis direction) and back side (negative Z-axis direction) of the lower part of the mounting portion 37 to the left and right, respectively, and a cylindrical shaft portion 31 is formed in the front-to-rear direction between each pair of arms 35.

[0041] Of the two shaft portions 31, the first shaft portion 31a is a portion corresponding to the second cylindrical portion 21b of the first bearing part 20a. The second shaft portion 31b is a portion corresponding to the second cylindrical portion 21b of the second bearing part 20b. The axial directions of the first shaft portion 31a and the second shaft portion 31b are parallel to each other (including approximately parallel within a range that includes an error).

[0042] For each of the first shaft portion 31a and the second shaft portion 31b, a first claw portion 33a and a second claw portion 33b are provided on the side surface of the mounting portion 37 facing the shaft portion, with their tips facing the respective shaft portion 31. When viewed in the XY cross section, the tips are wedge-shaped, tapering toward the corresponding shaft portion 31. Between the shaft portion 31 and the claw portion 33, there is a space in which the thick portion of the tube related to the cylindrical portion 21 of the bearing part 20 is positioned.

[0043] On the other hand, when looking at the connecting part 6 as a whole (see Figures 3 to 5), the first shaft part 10a, the first bearing part 20a, the intermediate part 30, the second bearing part 20b, and the second shaft part 10b are molded in series in this order, and as a result, the rotation axes of the shafts and bearings of the connecting part 6 are all set to be parallel (approximately parallel within the range of error).

[0044] As described above, the shaft part 10 and the intermediate part 30 are made by the first injection molding using the first resin material, and the bearing part 20 is made by the second injection molding using the second resin material. Therefore, the shaft part 10 and the intermediate part 30 made by the first injection molding essentially function as insert parts for the second injection molding (meaning that they are integrally molded in a subsequent molding process in which a different part is made for the part made in the previous molding process).

[0045] 9 is an enlarged cross-sectional view of the periphery of the connection portion between the first shaft part 10a and the first bearing part 20a, in the state of the injection kit 8. The cross section is an XY cross section. In the connecting part 6 of the injection kit 8 (see FIG. 2), the cylindrical portion 21 of the bearing part 20 is formed on the outside of the shaft portion 11 of the shaft part 10. Similarly, the cylindrical portion 21 of the bearing part 20 is formed on the outside of the shaft portion 31 of the intermediate part 30. In addition, an arm portion 15 and an arm portion 35 are formed on the shaft ends of the shaft portion 11 and the shaft portion 31, respectively. In the connecting part 6 in the state of the injection kit 8, the claw portion 13 of the first shaft part 10a is formed in a state engaged with the groove portion 22c of the first bearing part 20a.

[0046] The relationship around the connection between the second shaft part 10b and the second bearing part 20b is the same as that in FIG. 9 except that the left and right directions are reversed, and therefore a description thereof will be omitted.

[0047] 9, the side surface in the X-axis direction of the first movable range limiting portion 26 of the first bearing part 20a (see FIG. 7) abuts against the side surface (movable range limiting surface 16; see FIG. 6) of the arm portion 15 of the first shaft part 10a, preventing clockwise rotation (see FIG. 3). Also, since the large diameter portion 23 is located on the clockwise side of the groove portion 22c, even if the user tries to rotate the first shaft part 10a in the clockwise direction around the shaft portion 11, the upper surface of the claw portion 13 abuts against the large diameter portion 23, preventing rotation.

[0048] Conversely, when the user tries to rotate the first shaft part 10a counterclockwise around the shaft portion 11, the claw portion 13 must overcome the groove of the groove portion 22c, so the user feels a firm sense of operation. Paradoxically, the state of FIG. 9 is firmly held.

[0049] When the claw portion 13 climbs over the groove of the groove portion 22c, it moves toward the adjacent groove portion 22b while sliding against the outer circumferential surface of the movable range Am (see FIG. 7). At this time, since the first resin material of the first shaft part 10a is harder than the second resin material of the first bearing part 20a, the claw portion 13 slides against the outer circumferential surface of the movable range Am while bending it while maintaining the tip shape of the wedge shape.

[0050] When the claw portion 13 reaches the adjacent groove portion 22b, the tip of the claw portion 13 fits into the adjacent groove portion. At this time, the sliding resistance between the claw portion 13 and the outer circumferential surface of the movable range Am is suddenly released at the moment of fitting, so the user feels an appropriate click that the next groove portion has been reached. Then, as the fitting is completed, the claw portion 13 and the adjacent groove portion 22b are now firmly held.

[0051] 10 is an enlarged cross-sectional view of the periphery of the connection portion between the intermediate part 30 and the first bearing part 20a, in the state of the injection kit 8. The cross section is an XY cross section. In the connecting part 6 of the injection kit 8, the second cylindrical portion 21b of the first bearing part 20a is formed on the outer side of the first shaft portion 31a of the intermediate part 30. Also, an arm portion 35 is formed on the shaft end of the first shaft portion 31a. In the connecting part 6 in the state of the injection kit 8, the first claw portion 33a of the intermediate part 30 is formed in a state engaged with the groove portion 22c of the second cylindrical portion 21b of the first bearing part 20a.

[0052] The relationship around the connection between the second shaft portion 31b of the intermediate part 30 and the first cylindrical portion 21a of the second bearing part 20b is the same as that in FIG. 10 except that the left and right directions are reversed, so a description thereof will be omitted.

[0053] 9, around the connection part between the intermediate part 30 and the first bearing part 20a, and around the connection part between the intermediate part 30 and the second bearing part 20b, the effect of limiting the movable range, imparting a clicking sensation during operation, and firmly retaining the state due to the engagement between the claw part 33 and the groove part 22 is exhibited. Note that by forming the claw part 33 from the first resin material that is harder than the second resin material forming the groove part 22, the holding force and durability are increased, which is preferable.

[0054] Next, examples of how the connecting parts 6 can be used will be described. Fig. 11 is a front view of the connecting part 6 in the first usage mode, including a partially enlarged view showing an example of the positional relationship of engagement between the claw portion 13 of the first shaft part 10a and the groove portion 22 of the first bearing part 20a in this usage mode. Fig. 12 shows an example of the connecting part 6 of the armament item 4 in the first usage mode.

[0055] The connecting parts 6 in the injection kit 8 state have a linear appearance as a whole when viewed from the front. The armament item 4 has three exterior parts, broadly divided into a first exterior part 41, a second exterior part 42, and a third exterior part 43. The first exterior part 41 is the first connection target part 9a (see FIG. 3) for the armament item 4, and is attached to the attachment part 17 of the first axis part 10a. The second exterior part 42 is the second connection target part 9b (see FIG. 3) for the armament item 4, and is attached to the attachment part 17 of the second axis part 10b. The third exterior part 43 is the third connection target part 9c (see FIG. 3) for the armament item 4, and is attached to the attachment part 37 of the intermediate part 30. Therefore, by setting the connecting parts 6 to the first usage form, the armament item 4 has a linear style.

[0056] Fig. 13 is a front view of the connecting part 6 in the second usage mode, including a partially enlarged view showing an example of the positional relationship of engagement between the claw portion 13 of the first shaft part 10a and the groove portion 22 of the first bearing part 20a in this usage mode. Fig. 14 shows an example of the connecting part 6 of the armament item 4 in the second usage mode.

[0057] In the second usage form, the claw portion 13 of the first shaft part 10a engages with the middle groove portion 22b of the three groove portions 22 of the first cylindrical portion 21a of the first bearing part 20a. Also, in the intermediate part 30, the first claw portion 33a engages with the middle groove portion 22b of the three groove portions 22 of the second cylindrical portion 21b of the first bearing part 20a, and the second claw portion 33b engages with the middle groove portion 22b of the second cylindrical portion 21b of the second bearing part 20b. And the claw portion 13 of the second shaft part 10b engages with the middle groove portion 22b of the first cylindrical portion 21a of the second bearing part 20b.

[0058] Therefore, when the connecting parts 6 are viewed from the front, they have a shape bent at both ends that opens on the rear side. By using the connecting parts 6 in the second usage form, the weapon item 4 has a style bent at both ends, as shown in FIG.

[0059] Fig. 15 is a front view of the connecting part 6 in the third usage mode, and includes a partially enlarged view showing an example of the positional relationship of engagement between the second claw 33b of the intermediate part 30 and the groove 22 of the second cylindrical part 21b of the second bearing part 20b in this usage mode, and the positional relationship of engagement between the claw 13 of the second shaft part 10b and the groove 22 of the first cylindrical part 21a of the second bearing part 20b. Fig. 16 shows an example of the connecting part 6 of the armament item 4 in the third usage mode.

[0060] In the third usage mode, the relative position and orientation between the first shaft part 10a and the first bearing part 20a are the same as those in the first usage mode. The relative position and orientation between the first bearing part 20a and the intermediate part 30 are also the same as those in the first usage mode.

[0061] On the other hand, on the right side of the intermediate part 30, the second claw portion 33b engages with the bottommost groove portion 22a of the second cylindrical portion 21b of the second bearing part 20b. And the claw portion 13 of the second shaft part 10b engages with the groove portion 22a of the first cylindrical portion 21a of the second bearing part 20b.

[0062] Therefore, when the connecting part 6 is viewed from the front, the left side is linear and the right side is folded, centered around the intermediate part 30. By putting the connecting part 6 in the third usage form, as shown in Fig. 16, the weapon item 4 has a style in which the first exterior part 41 and the third exterior part 43 are aligned in a straight line, with the second exterior part 42 attached to the backside of them.

[0063] As described above, according to this embodiment, the shaft part 10 and the intermediate part 30 are molded in the first injection molding, and the bearing part 20 is molded by insert molding using the shaft part 10 and the intermediate part 30 as an insert part, and the connecting part 6 in a state in which the shaft part 10, the intermediate part 30, and the bearing part 20 are connected in advance is provided as an injection kit 8. The user only needs to cut out the connecting part 6 from the runner, and does not need to take the time to assemble the connecting part 6 itself. The fact that this assembly work can be omitted is a more useful point of this embodiment when a large number of connecting parts 6 of the same structure are required. In addition, since the shaft part 10, the intermediate part 30, and the bearing part 20 are connected in advance at the molding stage as described above, it can be said that the connecting part 6 itself is provided in a state with high precision compared to the case in which the user assembles the connecting part 6 by himself. More specifically, since there is less variation in the amount of engagement between the claw part and the groove part for each connecting part 6, the kit is provided in a state in which the holding force intended by the kit provider is easily exerted by the engagement between the claw part and the groove part. And, according to the connecting part 6, the relative positional relationship between the parts to be connected can be maintained more reliably than before.

[0064] It should be noted that the embodiments to which the present invention can be applied are not limited to the above examples, and additions, omissions, and modifications of components are possible as appropriate without departing from the spirit of the invention.

[0065] For example, the shape of a toy using the connecting parts 6 is not limited to the examples of the humanoid toy 2 and the weapon item 4. The connecting parts 6 can be applied to any toy that has a movable part in the same way.

[0066] In addition, it is also possible to reverse the convex and concave sides of the concave and convex relationships for any one or all of the following in the connecting part 6: 1) the concave and convex relationship between the claw portion 13 and the groove portion 22, 2) the concave and convex relationship between the first claw portion 33a and the groove portion 22, and 3) the concave and convex relationship between the second claw portion 33b and the groove portion 22. In other words, it is also possible to configure the first engaging portion of the shaft part 10 to be a groove portion, and the second engaging portion of the bearing part 20 to be a claw portion. In addition, the order of injection molding can also be changed as appropriate. For example, the bearing part 20 may be molded by a first injection molding using a first resin material, and the shaft part 10 and the intermediate part 30 may be molded by a second injection molding using a second resin material.

[0067] In the above embodiment, the connecting part 6 is exemplified as a quadruple-jointed movable part, but it can also be configured as a double-jointed movable part. Specifically, it is also possible to omit the intermediate part 30 and the second bearing part 20b from the connecting part 6 of the above embodiment, and engage the shaft part 11 of the second shaft part 10b with the second cylindrical part 21b of the first bearing part 20a.

[0068] Furthermore, the connecting part 6 can be a movable part with a single joint. Specifically, the intermediate part 30, the second bearing part 20b, and the second shaft part 10b are omitted from the connecting part 6 of the above embodiment. Also, the first bearing part 20a of the above embodiment can be configured such that the second cylindrical part 21b is replaced with the mounting part 17. [Explanation of symbols]
