Description

Technical Field

[0001] The present invention relates to an article holding device for holding articles such as bottles and cups. Background Art

[0002] Patent Document 1 discloses a cup holder as an example of an article holding device. The cup holder includes a base portion and an arm connected to the base portion via a spiral spring. The arm retracts into the base portion or protrudes from the base portion through an opening provided in the base portion.

[0003] The base portion includes a left side wall and a right side wall each formed with a guide groove. The above-mentioned opening is sandwiched between the left side wall and the right side wall. The guide grooves of the base portion extend obliquely downward such that the portion closer to the bottom of the base portion is farther away from the opening.

[0004] The arm includes a left side wall and a right side wall. The left side wall and the right side wall of the arm each have a shaft portion that fits into a corresponding guide groove. The shaft portion moving along the guide groove (i) retracts the arm from the opening of the base portion or (ii) protrudes the arm from the opening of the base portion.

[0005] The spiral spring biases the arm to protrude from the opening of the base portion. When a cup is placed in the cup holder, the pressing force of the cup overcomes the biasing force of the spiral spring and retracts the arm from the opening. When the cup is removed from the cup holder, the biasing force of the spiral spring causes the arm to protrude from the opening. Prior Art Documents Patent Documents

[0006] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2010-241181 Summary of the Invention Problems to be Solved by the Invention

[0007] As described above, the two shaft portions move along the two guide grooves to (i) protrude the arm from the opening or (ii) retract the arm from the opening. On the other hand, mounting the two shaft portions in the two guide grooves requires temporarily expanding the interval between the two guide grooves with a finger or the like. Although the long length of the two shaft portions suppresses the shaft portions from coming off the guide grooves, it requires a relatively large expansion of the interval between the two guide grooves. Therefore, in the above-mentioned article holding device, there is an urgent need to suppress the detachment of the shaft portions and reduce the load of mounting the shaft portions to the guide grooves. Means for Solving the Problems

[0008] According to one aspect of the present invention, there is provided an article holding device including: a holder having a storage portion configured to store an article; and an arm configured to enter the storage portion to hold the article and configured to exit the storage portion. Either the holder or the arm has a shaft portion, and the other of the holder and the arm has a guide portion. The guide portion includes an operation portion and a mounting portion. The mounting portion is connected to the operation portion and is bent with respect to the operation portion. When the shaft portion relatively moves along the operation portion, the arm enters or exits the storage portion. After the shaft portion moves along the mounting portion, the shaft portion moves in a direction bent toward the operation portion, and thus is received from the mounting portion into the operation portion.

[0009] According to one aspect of the present invention, there is provided an article holding device including: a holder having a storage portion, the holder being configured to store an article; an arm configured to enter the storage portion to hold the article and configured to exit the storage portion; and a biasing portion that biases the arm so that the arm enters the storage portion. Either the holder or the arm has a shaft portion, and the other of the holder and the arm has a guide portion. The guide portion has an opening portion that receives the shaft portion. When the shaft portion relatively moves along the guide portion, the arm enters or exits the storage portion. Either the holder or the arm is a contact member, and the contact member has a restricting portion. The restricting portion is disposed on a path of relative movement of the biasing portion with respect to the contact member. The restricting portion is configured to restrict displacement of the shaft portion from the opening portion by contacting the biasing portion even if the biasing portion is displaced with respect to the contact member.

[0011] [Article holding device 10] As Figure 1 shown, the article holding device 10 includes a holder 20 and an arm 30. The holder 20 includes a storage part 21, a shaft part 22, and a connecting part 23. In addition, for the sake of facilitating the description of the structure of the holder 20, Figure 1 two of the four arms 30 are omitted. Articles held by the article holding device 10 are cups having a cylindrical shape, a frustum shape, bottles having a cylindrical shape, a frustum shape, or a cylindrical shape with a thinner middle part, etc.

[0012] [Holder 20] The storage part 21 has a bottomed cylindrical shape extending in the vertical direction. The storage part 21 includes four openings 21P arranged at equal intervals in the circumferential direction of the storage part 21. The openings 21P extend downward from the upper edge part 21E of the storage part 21. The openings 21P are sandwiched by two support walls 21W protruding radially outward from the outer peripheral surface of the storage part 21. The two support walls 21W have a flat plate shape extending in the vertical direction and are arranged in the left-right direction. The shaft part 22 and the connecting part 23 are formed integrally with the two support walls 21W.

[0013] One shaft part 22 is provided on each of the one support walls 21W. The two shaft parts 22 are arranged at the upper part of the support walls 21W so as to face each other with the opening 21P interposed therebetween. The shaft part 22 integrated with one support wall 21W extends toward the other support wall 21W. The two shaft parts 22 are arranged to face each other.

[0014] One connecting part 23 is provided on each of the two support walls 21W. The connecting part 23 is arranged at the middle in the vertical direction of the support walls 21W. The connecting part 23 connects the two support walls 21W. Each one connecting part 23 includes one holder stopper part 23A and a first restricting part 23B. The holder 20 having the first restricting part 23B is an example of an abutting member.

[0015] The cage stop portion 23A faces the inside of the housing portion 21. The cage stop portion 23A has a groove shape extending in the vertical direction. The cage stop portion 23A has a shape of a spring arm 42 that hooks the torsion spiral spring 40. The cage stop portion 23A and the first restriction portion 23B are arranged in the left-right direction in which the shaft portion 22 extends. The first restriction portion 23B has a groove shape extending in the vertical direction. The first restriction portion 23B has a shape that receives the spring arm 42 that rotates together with the arm 30.

[0016] [arm 30] As Figure 2 shown, the arm 30 includes a holding wall 31 and two guide walls 32. The holding wall 31 has a beak shape that protrudes radially inward of the housing portion 21 toward the inside of the housing portion 21. The protruding end of the holding wall 31 is the inner end 30T of the arm 30. The holding wall 31 is disposed between the two support walls 21W. The holding wall 31 includes a first holding inclined surface 31T and a second holding inclined surface 31B. The first holding inclined surface 31T extends from the upper end of the opening 21P toward the lower inside of the housing portion 21. The second holding inclined surface 31B extends from the lower end of the first holding inclined surface 31T toward the lower end of the opening 21P.

[0017] The two guide walls 32 have a flat plate shape that extends along the support wall 21W. The two guide walls 32 are disposed in a side-by-side manner in the left-right direction. The two guide walls 32 are integral with the holding wall 31. The two guide walls 32 are disposed between the two support walls 21W. The two guide walls 32 face each other with the holding wall 31 interposed therebetween.

[0018] The lower end portion of the guide wall 32 is provided with a stopper 32A. The stopper 32A protrudes toward the outside of the support wall 21W. The stopper 32A abuts against the outer end surface of the support wall 21W on the outside of the housing portion 21, thereby restricting the lower end portion of the arm 30 from entering the inside of the housing portion 21.

[0019] [Guide portion] As Figure 3 shown, the arm 30 includes a hooking wall 33. The hooking wall 33 has a flat plate shape that extends from the inner end 30T of the arm 30 toward the rear end. The hooking wall 33 is disposed at the middle in the vertical direction of the arm 30. The hooking wall 33 connects the two guide walls 32 between the two guide walls 32.

[0020] The rear end portion of the hooking wall 33 is provided with two arm stoppers 33A. The two arm stoppers 33A are recessed from the rear end of the arm 30 toward the inner end 30T. The two arm stoppers 33A are arranged in the left-right direction.

[0021] Return Figure 2, the torsion spiral spring 40 is an example of a biasing portion. The torsion spiral spring 40 is mounted on two shaft portions 22. The torsion spiral spring 40 includes a spiral portion 41 and two spring arms 42. In the extending direction of the shaft portion 22, the length of the spiral portion 41 is longer than the sum of the lengths of the two shaft portions 22. The two shaft portions 22 are inserted into the spiral portion 41 and are spaced apart in the extending direction of the shaft portion 22 within the spiral portion 41. The two spring arms 42 extend from both axial ends of the spiral portion 41 in the tangential direction of the spiral portion 41. One spring arm 42 is hooked on the cage stopper portion 23A. The other spring arm 42 is hooked on one arm stopper portion 33A.

[0022] The torsion spiral spring 40 biases the arm stopper portion 33A with respect to the cage stopper portion 23A so that, when viewed from the axial direction of the spiral portion 41, the angle formed by the two spring arms 42 is enlarged. Thus, the torsion spiral spring 40 biases the arm 30 so that the arm 30 enters the storage portion 21.

[0023] Return Figure 3 , the arm 30 is provided with one guiding portion 35 on each of the one guiding walls 32. The guiding portion 35 is a through groove that penetrates the guiding wall 32. The guiding portion 35 communicates the space outside the arm 30 with the space sandwiched by the two guiding walls 32. The groove width of the guiding portion 35 is sized for the shaft portion 22 to pass through and is sized such that the relative movement of the shaft portion 22 with respect to the guiding portion 35 is along the extending direction of the guiding portion 35.

[0024] The guiding portion 35 has an inverted L shape composed of an operating portion 35B and a mounting portion 35A. The mounting portion 35A is connected to the operating portion 35B by bending. The mounting portion 35A has a linear shape extending from the hook wall 33 toward the upper inner side of the storage portion 21. The operating portion 35B has a gentle arc shape. The operating portion 35B extends along the front-rear direction, which is the direction from the rear end of the arm 30 toward the inner end 30T. The outer end of the operating portion 35B is closed. The inner end of the operating portion 35B is a connecting portion 35B1 connected to the mounting portion 35A.

[0025] The mounting portion 35A includes a first end portion 35A1 and a second end portion 35A2. The first end portion 35A1 of the mounting portion 35A is connected to the connecting portion 35B1 of the operating portion 35B. The second end portion 35A2 opens downward. The hook wall 33 is provided with a through groove connected to the second end portion 35A2 of the mounting portion 35A. The second end portion 35A2 of the mounting portion 35A and the through groove of the hook wall 33 form an opening portion 36. The opening portion 36 extends along the extending direction of the shaft portion 22.

[0026] The opening 36 receives the shaft portion 22 into the guiding portion 35. The mounting portion 35A guides the shaft portion 22 to the operating portion 35B through the relative movement of the shaft portion 22 along the mounting portion 35A. The mounting portion 35A is connected to the operating portion 35B in such a manner that the movement of the shaft portion 22 along the mounting portion 35A bends toward the operating portion 35B. The operating portion 35B receives the shaft portion 22 from the connecting portion 35B1. The operating portion 35B moves the arm 30 forward and backward relative to the storage portion 21 through the relative movement of the shaft portion 22 along the operating portion 35B.

[0027] [Installation Operation] As Figure 4 shown in the lower left side of [], the operation of installing the arm 30 on the cage 20 first configures the arm 30 in a posture where it is reversed front and back and up and down, and inserts the guiding portion 35 and the inner end 30T of the holding wall 31 from below the connecting portion 23 toward the opening 21P.

[0028] Next, as Figure 4 shown in the upper left side of [], the arm 30 is configured in a posture where the front and back and up and down are matched, and the opening 36 of the arm 30 is arranged above the shaft portion 22. Next, after receiving the shaft portion 22 into the opening 36 of the arm 30, the shaft portion 22 is relatively moved along the mounting portion 35A from the second end portion 35A2 of the mounting portion 35A toward the first end portion 35A1. Then, the shaft portion 22 is relatively moved along the operating portion 35B from the connecting portion 35B1 of the operating portion 35B toward the outer end portion of the operating portion 35B.

[0029] Thereby, as Figure 4 shown on the right side of [], with the stopper 32A arranged outside the support wall 21W and the arm 30 arranged inside the connecting portion 23, the shaft portion 22 is arranged inside the operating portion 35B.

[0030] Next, starting from the state where the shaft portion 22 is arranged inside the operating portion 35B, the two shaft portions 22 are installed into the spiral portion 41 of the torsion spiral spring 40. At this time, one spring arm 42 is hooked on the cage stopper portion 23A and the other spring arm 42 is hooked on one arm stopper portion 33A.

[0031] Thereby, the arm stopper portion 33A is urged toward the inside of the storage portion 21 relative to the cage stopper portion 23A so that the arm 30 enters the storage portion 21. In addition, the shaft portion 22 is urged inside the operating portion 35B in such a manner that the shaft portion 22 faces the outer end portion of the operating portion 35B, that is, the shaft portion 22 is moved away from the connecting portion 35B1 of the operating portion 35B.

[0032] [Function] As Figure 2As shown, one of the two spring arms 42 continuous with the spiral portion 41 is hooked on the cage stopper portion 23A. As Figure 5 shown, the other of the two spring arms 42 is hooked on the hooking wall 33. When no external force acts on the arm 30, the acting force of the torsion spiral spring 40 positions the first holding inclined surface 31T and the second holding inclined surface 31B inside the storage portion 21. The acting force of the torsion spiral spring 40 causes the shaft portion 22 to separate from the connecting portion 35B1 of the operating portion 35B and presses the shaft portion 22 against the outer end of the operating portion 35B.

[0033] When starting to store an article, a pressing force that presses down the arm 30 acts on the first holding inclined surface 31T from the article. The downward pressing force acting on the first holding inclined surface 31T causes the article to move downward relative to the first holding inclined surface 31T along the first holding inclined surface 31T.

[0034] At this time, the relative movement of the operating portion 35B with respect to the shaft portion 22 is restricted in the vertical direction. On the other hand, the relative movement of the operating portion 35B with respect to the shaft portion 22 is limited to (a) a leftward rotation about the shaft portion 22 and (b) a movement along the operating portion 35B that brings the connecting portion 35B1 closer to the shaft portion 22. (a) The rotation of the operating portion 35B and (b) the movement of the shaft portion 22 along the operating portion 35B are suppressed by the acting force of the torsion spiral spring 40. Therefore, if the downward pressing force acting on the first holding inclined surface 31T is greater than the acting force of the torsion spiral spring 40, then (a) the operating portion 35B rotates leftward or (b) the shaft portion 22 approaches the connecting portion 35B1. As a result, the arm 30 exits from the storage portion 21.

[0035] When starting to take out an article, a pressing force that pushes up the arm 30 acts on the second holding inclined surface 31B from the article. The upward pressing force acting on the second holding inclined surface 31B causes the article to move upward relative to the second holding inclined surface 31B along the second holding inclined surface 31B.

[0036] At this time, the relative movement of the operating portion 35B with respect to the shaft portion 22 is restricted in the vertical direction. On the other hand, the relative movement of the operating portion 35B with respect to the shaft portion 22 is limited to (a) a rightward rotation about the shaft portion 22 and (b) a movement along the operating portion 35B that brings the connecting portion 35B1 closer to the shaft portion 22. (a) The rotation of the operating portion 35B and (b) the movement of the shaft portion 22 along the operating portion 35B are suppressed by the acting force of the torsion spiral spring 40. Therefore, if the upward pressing force acting on the second holding inclined surface 31B is greater than the acting force of the torsion spiral spring 40, then (a) the operating portion 35B rotates rightward or (b) the shaft portion 22 approaches the connecting portion 35B1. As a result, the arm 30 exits from the storage portion 21.

[0037] In addition, when the coefficient of friction between the article and the holding wall 31 is large, the pressing force applied by the article to the holding wall 31 is easily converted into the rotation of the (a) operating portion 35B. When the coefficient of friction between the article and the holding wall 31 is small, the pressing force applied by the article to the holding wall 31 is easily converted into the movement of the (b) shaft portion 22 along the operating portion 35B.

[0038] As described above, the movement of the (b) shaft portion 22 along the operating portion 35B is accompanied by the movement of the spring arm 42 caused by the hooking wall 33 that overcomes the acting force of the torsion spiral spring 40. Moreover, the movement of the (b) shaft portion 22 along the operating portion 35B brings the shaft portion 22 closer to the connecting portion 35B1. When the coefficient of friction between the article and the holding wall 31 is large, the pressing force applied by the article to the holding wall 31 is easily converted into the movement of the (b) shaft portion 22 along the operating portion 35B. Therefore, it is easy to bring the shaft portion 22 closer to the connecting portion 35B1.

[0039] As Figure 6 shown, the cage 20 has a first restricting portion 23B of the connecting portion 23 on the path of the relative movement of the spring arm 42 with respect to the shaft portion 22. Therefore, the movement of the spring arm 42 caused by the hooking wall 33 is allowed until the spring arm 42 abuts against the first restricting portion 23B. Moreover, the movement of the spring arm 42 caused by the hooking wall 33 is stopped by the abutment of the spring arm 42 against the first restricting portion 23B. Thus, the movement of the (b) shaft portion 22 along the operating portion 35B stops before the shaft portion 22 reaches the connecting portion 35B1.

[0040] [Effect] As described above, according to the above-described embodiment, the following effects can be obtained. (1) In the installation operation, the shaft portion 22 received by the installation portion 35A moves along the installation portion 35A and enters the operating portion 35B connected to the installation portion 35A. The movement of the shaft portion 22 along the installation portion 35A is bent toward the operating portion 35B. Therefore, it is possible to suppress the detachment of the shaft portion 22 from the operating portion 35B and reduce the load of deforming the operating portion 35B when the shaft portion 22 is installed in the guiding portion 35.

[0041] (2) In the installation operation, the shaft portion 22 received by the guiding portion 35 enters the operating portion 35B through the opening portion 36 via the installation portion 35A. The opening portion 36 includes the second end portion 35A2 of the installation portion 35A. Therefore, it is easy for the operator to intuitively grasp the operation method of installing the shaft portion 22 in the guiding portion 35.

[0042] (3) The arm 30 is urged by the torsion spiral spring 40 so that the arm 30 enters the storage portion 21. Therefore, the holding suitable for the size and shape of the article can be achieved by the arm 30.

[0043] (4) Since the shaft portion 22 has both the function of guiding the forward and backward movement of the arm 30 and the function of supporting the torsion coil spring 40, the number of components of the cage 20 can also be reduced. (5) Since the movement of the spring arm 42 is restricted by the first restricting portion 23B, the relative movement of the shaft portion 22 with respect to the operating portion 35B is suppressed within a specified range. The relative movement of the shaft portion 22 with respect to the operating portion 35B being suppressed within a specified range stabilizes the movable range of the arm 30 with respect to the cage 20.

[0044] (6) In particular, since the relative movement of the shaft portion 22 with respect to the operating portion 35B is suppressed within a specified range that does not include the connecting portion 35B1, it is difficult for the shaft portion 22 that enters the operating portion 35B from the mounting portion 35A to return to the mounting portion 35A. Therefore, the reproducibility of the relative movement of the shaft portion 22 along the operating portion 35B is improved.

[0045] The above-described embodiment can also be modified and implemented as follows. [Modification Example 1: Restricting Portion] · The first restricting portion 23B may be arranged such that the first restricting portion 23B abuts against the spring arm 42 when the shaft portion 22 is in the middle of the operating portion 35B in the extending direction of the operating portion 35B. For example, the first restricting portion 23B may be arranged at a position closer to the inside of the accommodating portion 21 than the cage stopper portion 23A.

[0046] [Modification Example 2] · As Figure 7 shown, the arm 30 may also include an upper restricting portion 38 and a lower restricting portion 39. The upper restricting portion 38 and the lower restricting portion 39 are each an example of a second restricting portion. The upper restricting portion 38 and the lower restricting portion 39 are ribs integrally formed with the outer surface of the holding wall 31. The upper restricting portion 38 is arranged above the lower restricting portion 39. The upper restricting portion 38 strengthens the upper part of the holding wall 31. The lower restricting portion 39 is integral with the hooking wall 33. The lower restricting portion 39 strengthens the hooking wall 33.

[0047] The upper restricting portion 38 and the lower restricting portion 39 are away from the two guiding walls 32 and are arranged between the two guiding walls 32. The upper restricting portion 38 and the lower restricting portion 39 are spaced apart from the shaft portion 22 by a length in the extending direction of the shaft portion 22 from the guiding walls 32. In other words, the gap between the upper restricting portion 38 and the guiding wall 32 is sized to allow the shaft portion 22 to pass through in the extending direction of the shaft portion 22. The gap between the upper restricting portion 38 and the guiding wall 32 is sized to allow the shaft portion 22 to pass through in the extending direction of the shaft portion 22. Thereby, the upper restricting portion 38 and the lower restricting portion 39 allow the shaft portion 22 to be received into the guiding portion 35.

[0048] As Figure 8As shown, when viewed from a viewpoint facing the guide wall 32, the connecting portion 35B1 of the upper restricting portion 38 and the operating portion 35B overlap. When viewed from a viewpoint facing the guide wall 32, the lower restricting portion 39 and the mounting portion 35A overlap.

[0049] As Figure 9 shown, when viewed from a viewpoint facing the guide wall 32, the upper restricting portion 38 is arranged to restrict the helical portion 41 of the torsion coil spring 40 from passing through the connecting portion 35B1. When viewed from a viewpoint facing the guide wall 32, the lower restricting portion 39 is arranged to restrict the helical portion 41 of the torsion coil spring 40 from moving from the operating portion 35B to the mounting portion 35A.

[0050] As Figure 10 shown, in (b), as the shaft portion 22 moves along the operating portion 35B, the shaft portion 22 approaches the connecting portion 35B1 and the helical portion 41 approaches the connecting portion 35B1. In this regard, the arm 30 has the upper restricting portion 38 on the path of the relative movement of the helical portion 41 with respect to the arm 30. Therefore, the movement of the shaft portion 22 along the operating portion 35B is allowed until the helical portion 41 abuts against the upper restricting portion 38. Moreover, by the helical portion 41 abutting against the upper restricting portion 38, the movement of the shaft portion 22 along the operating portion 35B is suppressed.

[0051] Further, assuming that even if the arm 30 is further pressed so that the helical portion 41 returns to the mounting portion 35A beyond the upper restricting portion 38, the movement of the shaft portion 22 along the operating portion 35B is further suppressed by the helical portion 41 abutting against the lower restricting portion 39.

[0052] According to the above-described modification example 2, the following effects can be obtained. (7) The movement of the helical portion 41 is restricted by the upper restricting portion 38 and the lower restricting portion 39. Therefore, the relative movement of the shaft portion 22 with respect to the guiding portion 35 is restricted within a specified range. Restricting the relative movement of the shaft portion 22 with respect to the guiding portion 35 within a specified range stabilizes the movable range of the arm 30 with respect to the cage 20.

[0053] (8) In particular, since the relative movement of the shaft portion 22 with respect to the operating portion 35B is restricted within a specified range that does not include the connecting portion 35B1, it is difficult for the shaft portion 22 that enters the operating portion 35B from the mounting portion 35A to return to the mounting portion 35A. Further, even if the shaft portion 22 returns from the operating portion 35B to the mounting portion 35A, it is difficult for the shaft portion 22 to return to the opening 36. Therefore, the detachment of the arm 30 from the cage 20 is further suppressed.

[0054] [Modification Example 3] · The article holding device 10 may also omit at least one of the first restricting portion 23B, the upper restricting portion 38, and the lower restricting portion 39.

[0055] [Modification Example 4] · When the article holding device 10 includes at least one of the first restricting portion 23B, the upper restricting portion 38, and the lower restricting portion 39, the bending formed at the boundary between the mounting portion 35A and the operating portion 35B may also be omitted from the guiding portion 35 for the mounting portion 35A and the operating portion 35B.

[0056] According to the above Modification Example 4, even if the above (1) in which the shaft portion 22 bends toward the operating portion 35B based on the movement along the mounting portion 35A cannot be obtained, the effects of the above (5) to (8) can still be obtained.

[0057] [Modification Example 5: Shaft Portion 22] · The shaft portion 22 may be arranged at the lower part of the support wall 21W in the vertical direction, and the guiding portion 35 may be arranged at the lower part of the guiding wall 32 in the vertical direction. In addition, the stopper 32A may be arranged at the upper end of the guiding wall 32 or may be omitted from the guiding wall 32. At this time, the opening 36 may be arranged on the lower surface of the arm 30. Thus, the shaft portion 22 only needs to be configured to allow (a) the rotation of the guiding portion 35 around the shaft portion 22 and (b) the movement of the shaft portion 22 along the guiding portion 35, thereby withdrawing the arm 30 from the storage portion 21.

[0058] In addition, similar to Modification Example 4, when the article holding device 10 includes at least one of the first restricting portion 23B, the upper restricting portion 38, and the lower restricting portion 39, the bending formed at the boundary between the mounting portion 35A and the operating portion 35B may also be omitted from the guiding portion 35 for the mounting portion 35A and the operating portion 35B.

[0059] For example, the mounting portion 35A and the operating portion 35B may have a linear shape extending in the front-rear direction or may have an arc shape. Moreover, the opening 36 may be arranged on the inner surface of the holding wall 31 such as the second holding inclined surface 31B so as to open.

[0060] · Either the holder 20 or the arm 30 may be a contact member, and the article holding device 10 may include a biasing portion. The biasing portion biases the arm 30 so that the arm 30 enters the storage portion 21. An example of the biasing portion is a torsion coil spring 40. The article holding device 10 may also include a restricting portion 39T arranged on the relative movement path of the biasing portion with respect to the contact member. The restricting portion 39T restricts the relative movement of the shaft portion 22 along the guiding portion 35 within a specified range by the contact between the biasing portion and the restricting portion 39T. The article holding device 10 may also omit the first restricting portion 23B, the upper restricting portion 38, and the lower restricting portion 39, and only include the restricting portion 39T.

[0061] For example, as Figure 11As shown, the guiding portion 35 may also be a single linear shape without bends, similar to Modification Example 4. That is, the mounting portion 35A and the operating portion 35B may have a single linear shape extending in the front-rear direction, or may have a single arc shape. The shaft portion 22 may also move from the mounting portion 35A to the operating portion 35B without bending at the boundary between the mounting portion 35A and the operating portion 35B along the guiding portion 35.

[0062] At this time, the opening 36 may also open on the inner side surface of the arm 30 so that the shaft portion 22 passes from the inner side surface of the arm 30 toward the rear. The two openings 36 through which the two shaft portions 22 pass are arranged along the extending direction of the shaft portion 22. The two openings 36 are separated by a restricting portion 39T. The two openings 36 sandwiching the restricting portion 39T allow the shaft portion 22 to pass through the guiding portion 35 from the opening 36 along the extending direction of the guiding portion 35, respectively. On the other hand, the restricting portion 39T sandwiched by the two openings 36 restricts the spiral portion 41 mounted on the two shaft portions 22 from moving closer to the front of the paper surface than the restricting portion 39T. The restricting portion 39T in contact with the spiral portion 41 restricts the relative movement of the shaft portion 22 mounted with the spiral portion 41 from disengaging from the opening 36 along the guiding portion 35.

[0063] Here, as Figure 12 shown, the shaft portion 22 is arranged at the lower part of the support wall 21W in the up-down direction, similar to Modification Example 5. The guiding portion 35 is arranged at the lower part of the guiding wall 32 in the up-down direction. The shaft portion 22 allows (a) the rotation of the guiding portion 35 centered on the shaft portion 22 and (b) the movement of the shaft portion 22 along the guiding portion 35, thereby causing the arm 30 to withdraw from the storage portion 21. In the case where the withdrawal of the arm 30 largely includes a translational component of the arm 30, (b) the movement of the shaft portion 22 along the guiding portion 35 causes the arm 30 to withdraw and brings the shaft portion 22 closer to the opening 36 to a large extent.

[0064] Regarding this point, the restricting portion 39T is arranged on the path of the relative movement of the spiral portion 41 with respect to the arm 30. The relative movement of the spiral portion 41 with respect to the arm 30 corresponds to the relative movement of the shaft portion 22 with respect to the guiding portion 35. That is, the restricting portion 39T restricts the relative movement of the shaft portion 22 along the guiding portion 35 within a specified range by the contact between the restricting portion 39T and the spiral portion 41. As a result, even if the guiding portion 35 has a linear shape, the contact between the restricting portion 39T and the spiral portion 41 inhibits the shaft portion 22 from disengaging from the guiding portion 35. As a result, even when the withdrawal of the arm 30 largely includes a translational component of the arm 30, the shaft portion 22 can be continuously held within the guiding portion 35.

[0065] [Modification Example 6: Guiding Portion 35] ·Alternatively, the cage may have a guiding portion 35, and the arm 30 may have a shaft portion 22. In this case, one torsion spiral spring 40 may be provided for each shaft portion 22. Even with this configuration, the effects according to the above (1) to (6) can be obtained.

[0066] [Modification Example 7] ·The mounting portion 35A may also be a bottomed groove that does not penetrate the guiding wall 32. The operating portion 35B may also be a bottomed groove that does not penetrate the guiding wall 32. In addition, the entire guiding portion 35 may be a bottomed groove that does not penetrate the guiding wall 32. The guiding portion 35 only needs to have the mounting portion 35A, and the mounting portion 35A receives the shaft portion 22 that requires deformation of the operating portion 35B in the reception of the operating portion 35B through the relative movement of the arm 30 with respect to the cage 20.

[0067] For example, the two mounting portions 35A may have a structure in which the interval between the two mounting portions 35A becomes narrower toward the operating portion 35B in the extending direction of the shaft portion 22. The opening portion 36 may be the widest portion of the interval between the two mounting portions 35A and does not open at the edge of the arm 30.

[0068] [Modification Example 8] ·Alternatively, the mounting portion 35A may have a curved shape, and the operating portion 35B may have a linear shape extending in the tangential direction of the first end portion 35A1 of the mounting portion 35A.

[0069] [Modification Example 9] ·The mounting portion 35A may be connected to the middle of the operating portion 35B in the extending direction of the operating portion 35B. In other words, the connecting portion 35B1 may be arranged in the middle of the operating portion 35B in the extending direction of the operating portion 35B. Even with this configuration, the effects according to the above (1) to (5) can be obtained.

[0070] [Modification Example 10] ·The opening portion 36 may be constituted only by the second end portion 35A2 of the mounting portion 35A. The opening portion 36 only needs to have a length for receiving the shaft portion 22 in the extending direction of the shaft portion 22.

[0071] The following annexes the technical ideas derived from the above embodiments and modification examples. [Annex 1] An article holding device, characterized by comprising: a cage having a storage portion for storing an article; an arm that advances and retreats with respect to the storage portion to hold the article; and a biasing portion that biases the arm so that the arm enters the storage portion, either the cage or the arm has a shaft portion, The cage has a guiding portion other than the component in the arm. The relative movement of the shaft portion along the guiding portion causes the arm to move forward and backward. Either the cage or the arm is a contact member. The contact member has a restricting portion. The restricting portion is disposed on the path of the relative movement of the biasing portion with respect to the contact member, and the relative movement of the shaft portion along the guiding portion is restricted within a specified range by the contact between the biasing portion and the restricting portion.

[0072] According to the above-mentioned Note 1, during the displacement of the biasing portion that biases the arm toward the storage portion together with the movement of the arm, the restricting portion of the contact member contacts the biasing portion. The restricting portion that contacts the biasing portion restricts the displacement of the biasing portion with respect to the restricting portion, and further restricts the displacement of the shaft portion with respect to the guiding portion linked to this displacement within a specified range. Assuming that the guiding portion itself defines the displacement range of the shaft portion with respect to the guiding portion, the structure of the guiding portion is restricted to not only enable the relative movement of the shaft portion with respect to the guiding portion but also define the displacement range of the shaft portion. As a result, it is difficult to adopt a structure of the guiding portion suitable for the processing of the guiding portion or a structure of the guiding portion that suppresses the load when the shaft portion is mounted on the guiding portion. In this regard, according to the configuration of Note 1, the contact between the restricting portion and the biasing portion restricts the displacement of the shaft portion with respect to the guiding portion within a specified range, so that the design freedom of the guiding portion can be improved.

[0073] [Note 2] According to the article holding device described in Note 1, The biasing portion is a torsion helical spring having a spring arm. The torsion helical spring has a spring arm hooked to a stopper portion of the arm. The stopper portion allows the relative movement of the shaft portion with respect to the guiding portion by causing the spring arm to move relative to the shaft portion by an external force that withdraws the arm from the storage portion. The contact member is the cage having the shaft portion. The restricting portion is disposed on the path of the relative movement of the spring arm with respect to the shaft portion, and the displacement of the spring arm with respect to the shaft portion is restricted within a specified range by the contact between the spring arm and the restricting portion.

[0074] According to the above-mentioned Note 2, as shown in the example of the first restricting portion 23B, the movement of the spring arm is restricted by the restricting portion, so that the relative movement of the shaft portion with respect to the guiding portion can be suppressed within a specified range. [Note 3] According to the article holding device described in Note 1 or 2, The force - applying part is a torsion helical spring having a helical part mounted on the shaft part. The contact member is the arm having the guiding part. The restricting part is disposed on the path of the relative movement of the helical part with respect to the guiding part, and by the contact of the helical part with the restricting part, the displacement of the helical part with respect to the guiding part is restricted within a specified range.

[0075] According to the above - mentioned note 3, as shown in the examples of the upper - side restricting part 38 and the lower - side restricting part 39, the movement of the helical part is restricted by the restricting part, so that the relative movement of the shaft part with respect to the guiding part can be suppressed within a specified range.
