Description

Technical Field

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

Background Art

[0002] A cup holder, which is an example of an article holding device, includes a holder, a biasing portion, and an arm (see, for example, Patent Document 1). The holder includes a retractable opening and a bearing portion. The retractable opening of the holder allows the arm to retract and extend into the accommodating portion of the holder. The bearing portion of the holder is disposed below the retractable opening so as to protrude outward from the outer peripheral surface of the side wall toward the outside of the holder.

[0003] The lower end portion of the arm includes a shaft portion. The shaft portion pivotally supported by the bearing portion (i) withdraws the arm from the accommodating portion or (ii) allows the arm to enter the accommodating portion. The biasing portion biases the arm so as to cause the arm to enter the accommodating portion. When the cup is pushed toward the bottom of the holder, the pressing force exerted by the cup acts on the inclined surface of the arm. The pressing force acting on the inclined surface of the arm (i) withdraws the arm from the accommodating portion against the biasing force of the biasing portion so as to push out the inclined surface of the arm from the cup toward the outside of the holder. When the cup is pulled out of the holder, the biasing force of the biasing portion (ii) causes the arm to enter the accommodating portion.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Bottom covers made of silicone resin or ABS resin stabilize the bottle's position on the mounting surface. However, when a bottle with a bottom cover attached is placed in an item holding device, a large frictional force is generated between the bottom cover and the inclined surface of the arm. This frictional force between the bottle and the arm suppresses the relative movement of the bottle with respect to the inclined surface of the arm and makes it difficult to push the inclined surface of the arm out of the retraction opening. As a result, (i) the arm is prevented from exiting the storage area by excessive frictional force. [Means for solving the problem]

[0006] An article holding device for solving the above problems comprises a holder having a storage section that receives an article from above the storage section, and an arm which is a sliding contact surface that rotates around a shaft so that the upper part of the arm that contacts the article entering the storage section receives a downward external force from the article and retracts from the storage section, wherein the shaft is provided on either the holder or the arm, and a bearing is provided in addition to the member of the holder or the arm, the bearing is provided with a slot into which the shaft is inserted so that the rotation of the shaft relative to the slot and the translation of the shaft relative to the slot can be made by the external force, the slot has a shape in which the translation is suppressed by a biasing force and the upper part of the arm retracts as the shaft moves accompanied by the translation.

[0007] An article holding device for solving the above problems comprises: a holder having a storage section for receiving articles from above the storage section; and an arm having an upper arm portion extending downward inward from the storage section, the upper arm portion being a sliding contact surface that rotates around a shaft portion so as to receive a downward external force from the article entering the storage section and withdraw from the storage section; wherein the shaft portion is provided in either the holder or the arm, and a bearing portion is provided in addition to the member in the holder or the arm, the bearing portion has a slot extending downward outward from the storage section, and the slot into which the shaft portion is inserted is provided so as to enable the rotation of the shaft portion relative to the slot and the translation of the shaft portion relative to the slot by the external force, the slot is subjected to a biasing force which suppresses the translation and causes the upper arm portion to withdraw as the shaft portion moves accompanied by the translation.

[0008] According to each of the above article holding devices, a downward external force acting from the article on the upper part of the arm acts to push down the part of the upper part of the arm that is in contact with the article. In this case, if the coefficient of friction of the object is low, such as when the object is prone to sliding against the arm, the upper part of the arm is likely to slide against the object. Therefore, when the coefficient of friction of the object is low, the downward pressure of the object causes the upper part of the arm to rotate so that the part in contact with the object is displaced within the upper part of the arm. This causes the arm to retract from the housing.

[0009] On the other hand, when the coefficient of friction of an object is high, such as when the object is difficult to slide against the arm, the upper part of the arm is difficult to slide against the object. Therefore, when the coefficient of friction of the object is high, a downward external force moves the upper part of the arm so that the part in contact with the object is pushed down, while displacement of that part within the upper part of the arm is suppressed. At this time, the slot into which the shaft is inserted allows not only rotation of the shaft relative to the slot, but also translation of the shaft relative to the slot. Therefore, the downward external force includes translation in the movement of the shaft relative to the slot. As a result, even when the coefficient of friction of the object is high, the arm retracts from the housing. As a result, whether the coefficient of friction of the articles is low or high, the article holding device facilitates the storage of the articles.

[0010] In the article holding device described above, either the holder or the arm has a guide surface as a guide member, and the part of the holder and the arm other than the guide member has a guided part, the guided part moves along the guide surface due to the external force, and the guide member may link the movement of the shaft part relative to the slot to the movement of the guided part along the guide surface.

[0011] As described above, the shape of the slot allows for rotation and translation of the shaft. Movement of the shaft accompanied by translation can involve not only translation of the shaft, but also parallel translation and rotation of the shaft. In this respect, with the above configuration, the movement of the shaft relative to the slot is linked to the movement of the guided part along the guide surface. Therefore, even if the translation and rotation of the shaft are parallel, the amount of translation and rotation of the shaft is reproduced by the movement of the guided part along the guide surface. As a result, the item holding device can achieve reproducibility in the posture of the arm when it is withdrawn.

[0012] In the article holding device described above, the guide member is the holder, and the guide surface may extend from the outer peripheral surface of the housing portion toward the outside and downward of the housing portion. According to the above configuration, the movement of the guided portion along the guide surface of the holder is driven by a downward external force acting on the upper part of the arm. In this case, the guide surface of the holder extends outward and downward from the housing portion. Therefore, the movement of the guided portion along the guide surface, and consequently the translation and rotation of the shaft portion relative to the slot, are smoothly driven by the downward external force.

[0013] In the article holding device described above, the guided portion may be a projection extending from the side of the arm onto the guide surface. With the above configuration, since the guided portion is a projection extending from the side of the arm, it is easy to assemble the guided portion to the guide surface.

[0014] In the above-described article holding device, a biasing portion that is attached to the shaft portion and biases the arm inward may be provided, and the biasing portion may apply the biasing force to the shaft portion from a member having the slot.

[0015] According to the above configuration, the biasing portion that biases the arm inward also has a function of suppressing the translation of the shaft portion. Therefore, it is possible to reduce the number of members included in the article holding device as compared with a configuration in which members that bias the arm inward and members that suppress the translation of the shaft portion are provided separately.

[0016] In the above-described article holding device, the member having the bearing portion may include a mounting portion that is a passage for inserting the shaft portion into the slot from the outside of the member, and the mounting portion may extend in a direction different from the direction in which the slot extends.

[0017] According to the above configuration, the mounting portion for inserting the shaft portion into the slot extends in a direction different from the direction in which the slot extends. Therefore, it is possible to suppress the shaft portion from coming out of the slot. In the above-described article holding device, the mounting portion may include an opening through which the shaft portion passes at an end opposite to the end continuous with the slot.

[0018] According to the above configuration, the mounting portion for inserting the shaft portion into the slot includes an opening through which the shaft portion passes. Therefore, the operation of assembling the shaft portion into the slot becomes easy.

Advantages of the Invention

[0019] According to the article holding device of the present disclosure, the storage load of the article can be reduced.

MODE FOR CARRYING OUT THE INVENTION

[0021] [Article holding device 10] As shown in FIG. 1, the article holding device 10 includes a holder 20 and an arm 30. The holder 20 is an example of a guide member. The holder 20 includes a housing portion 21, a shaft portion 22, and a connecting portion 23. Note that, for the sake of convenience in explaining the structure of the holder 20, FIG. 1 omits two of the four arms 30. Articles held by the article holding device 10 are cups having a cylindrical or frustoconical shape, bottles having a cylindrical, frustoconical, or constricted cylindrical shape, and the like.

[0022] [Holder 20] The housing portion 21 has a bottomed cylindrical shape extending in the vertical direction. The holder 20 receives an article from above the housing portion 21. The housing portion 21 includes four advancing / retreating openings 21P equally arranged in the circumferential direction of the housing portion 21. The advancing / retreating openings 21P extend downward from the upper edge portion 21E of the housing portion 21. The advancing / retreating openings 21P are sandwiched between two support walls 21W protruding radially outward from the outer peripheral surface of the housing portion 21. The two support walls 21W have a flat plate shape extending in the vertical direction and are arranged side by side in the left-right direction. The shaft portion 22 and the connecting portion 23 are formed integrally with the two support walls 21W.

[0023] Each support wall 21W is provided with one shaft portion 22. The two shaft portions 22 are positioned at the bottom of the support wall 21W so as to face each other across the reciprocating opening 21P. One shaft portion 22, which is integrated with one support wall 21W, extends toward the other support wall 21W. The two shaft portions 22 are positioned so as to face each other.

[0024] Each of the two support walls 21W is provided with one connecting section 23. The connecting sections 23 are located on the upper part of the support walls 21W. The connecting sections 23 connect the upper ends of the two support walls 21W. Each connecting section 23 has one guide surface 23A on each support wall 21W. The guide surface 23A is the upper end surface of the support wall 21W.

[0025] The guide surface 23A protrudes from the outer circumferential surface of the housing portion 21 toward the outside and downward of the housing portion 21. The two guide surfaces 23A are aligned in the left-right direction. The guide surface 23A is a flat surface with an inclination, where the part closer to the housing portion 21 is located higher. The guide surface 23A extends radially beyond the shaft portion 22 of the housing portion 21. The guided boss 32A of the arm 30 is in contact with the guide surface 23A from above.

[0026] [Arm 30] As shown in Figure 2, the arm 30 includes a retaining wall 31 and a locking wall 32. The retaining wall 31 has a beak-like shape that protrudes toward the interior of the housing 21. The protruding end of the retaining wall 31 is the inner end of the arm 30. The retaining wall 31 includes a first driven inclined surface 31T, which is an example of the upper part of the arm, and a second driven inclined surface 31B.

[0027] The surface of the first driven inclined surface 31T is a sliding contact surface that extends from the upper end of the retractable opening 21P toward the inside and downward of the housing 21. The first driven inclined surface 31T is located lower the further it is located inside the housing 21. The inclination of the first driven inclined surface 31T toward the inside and downward is greater the further it is located inside the housing 21. The first driven inclined surface 31T has an elliptical arc shape when viewed from the axial direction of the shaft portion 22. The first driven inclined surface 31T is positioned to contact the article entering the housing 21 and to receive a downward external force from the article.

[0028] The second driven inclined surface 31B extends from the lower end of the first driven inclined surface 31T toward the lower end of the retractable opening 21P. The second driven inclined surface 31B is positioned higher the further it is located inside the housing section 21. The inclination of the second driven inclined surface 31B toward the inside and upward is approximately constant in each part located inside the housing section 21.

[0029] The locking wall 32 has a flat plate shape that extends vertically to cover the retractable opening 21P. The locking wall 32 is integral with the retaining wall 31. The retaining wall 31 protrudes inward from the inner surface of the locking wall 32. The locking wall 32 is positioned to protrude around the retaining wall 31. The locking wall 32 abuts against the periphery of the retractable opening 21P within the outer surface of the housing 21 from the outside of the housing 21. As a result, the inward movement of the housing 21 in the arm 30 is restricted by the locking wall 32.

[0030] The upper end of the locking wall 32 is provided with a guided boss 32A. The side end face of the locking wall 32 is the side of the arm 30. The guided boss 32A protrudes from the side of the arm 30 toward the guide surface 23A. The guided boss 32A abuts the guide surface 23A from above outside the housing portion 21. As a result, downward movement of the arm 30 is restricted by the guide surface 23A.

[0031] As shown in Figure 3, the arm 30 is provided with two latching walls 33. The two latching walls 33 are arranged side by side in the left-right direction. The latching walls 33 have a flat plate shape that protrudes outward from the outer surface of the locking wall 32. The latching walls 33 are positioned midway in the vertical direction of the locking wall 32. The rear end of the latching wall 33 is provided with an arm stopper portion 33A. The arm stopper portion 33A is recessed inward from the rear end of the arm 30.

[0032] The arm 30 is equipped with two bearing portions 35. The bearing portions 35 are located below the guided boss 32A and the hooking wall 33. The arm 30 is equipped with one bearing portion 35 for each shaft portion 22.

[0033] [Bearing portion 35] Returning to Figure 2, the bearing portion 35 protrudes outward from the lower part of the locking wall 32. The bearing portion 35 has a planar wall shape perpendicular to the locking wall 32. The two bearing portions 35 are arranged to face each other. The two bearing portions 35 are connected to each other at the lower end of the arm 30. The bearing portion 35 includes an operating portion 35A and a mounting portion 35B. The operating portion 35A and the mounting portion 35B are through grooves that penetrate the bearing portion 35, respectively. The operating portion 35A is an example of a slot.

[0034] The operating part 35A and the mounting part 35B each connect the outer space of the arm 30 to the space between the two bearing parts 35. The groove widths of the operating part 35A and the mounting part 35B are sized to allow the shaft 22 to pass through. The groove widths of the operating part 35A and the mounting part 35B allow the rotation of the shaft 22 relative to the bearing parts 35. The groove width of the operating part 35A allows the translation of the shaft 22 relative to the operating part 35A. The groove width of the operating part 35A may also be sized to guide the translation of the shaft 22 along the direction in which the operating part 35A extends. The groove width of the mounting part 35B may also be sized to guide the translation of the shaft 22 relative to the mounting part 35B along the direction in which the mounting part 35B extends.

[0035] The actuation part 35A has a straight shape extending outward and downward from the outer surface of the locking wall 32. The actuation part 35A is located lower the further it is located outside the housing part 21. The outward and upward inclination of the actuation part 35A is approximately constant at each part located outside the housing part 21. The upper end of the actuation part 35A is closed. The lower end of the actuation part 35A is connected to the mounting part 35B. The mounting part 35B is a passage for the shaft part 22 that is connected to the lower end of the actuation part 35A.

[0036] The mounting portion 35B has a straight shape extending from the lower end of the operating portion 35A toward the housing portion 21. The vertical position of the mounting portion 35B is substantially constant at each part in the radial direction of the housing portion 21. The outer end of the mounting portion 35B is connected to the operating portion 35A. The inner end of the mounting portion 35B is an opening. The opening of the mounting portion 35B allows the shaft portion 22 to pass through from the outside of the arm 30 toward the mounting portion 35B. The operating portion 35A and the mounting portion 35B have an inverted L-shape, which bends at the outer end of the mounting portion 35B. The arm 30 has a partition wall between the two mounting portions 35B, extending upward from the bottom of the arm 30. The partition wall of the arm 30 has a width smaller than the distance between the two shaft portions 22 in the left-right direction.

[0037] The mounting portion 35B guides the shaft portion 22 to the operating portion 35A by the relative movement of the shaft portion 22 along the mounting portion 35B. The mounting portion 35B is connected to the operating portion 35A such that the relative movement of the shaft portion 22 along the mounting portion 35B bends toward the operating portion 35A. The operating portion 35A receives the shaft portion 22 from the mounting portion 35B. The operating portion 35A moves the housing portion 21 forward and backward in the arm 30 by the relative movement of the shaft portion 22 along the operating portion 35A.

[0038] As shown in Figure 4, the article holding device 10 is equipped with a torsion coil spring 40. The torsion coil spring 40 is an example of a biasing part. The torsion coil spring 40 is mounted on two shaft portions 22.

[0039] As shown in Figure 5, the torsion coil spring 40 comprises one coil section 41 and two spring arms 42. The shaft section 22 is inserted through the coil section 41. The length of the coil section 41 in the direction in which the shaft section 22 extends forms a gap between the two shaft sections 22. The coil section 41 abuts against the bulkhead of the arm 30 as the shaft section 22 moves along the mounting section 35B toward the opening of the mounting section 35B, thereby restricting the shaft section 22 from coming out of the mounting section 35B. The two spring arms 42 extend tangentially to the coil section 41 from both ends in the axial direction of the coil section 41. One spring arm 42 is hooked to the bottom surface of the holder 20 through the opening in the mounting section 35B of the arm 30. The other spring arm 42 is hooked to one arm stopper 33A.

[0040] The torsion coil spring 40 acts a biasing force to widen the angle formed by the two spring arms 42 when viewed from the axial direction of the coil portion 41. The torsion coil spring 40 biases the arm stopper portion 33A in the circumferential direction of the shaft portion 22, centered on the shaft portion 22. The arm stopper portion 33A, biased in the circumferential direction of the shaft portion 22, biases the arm 30 inward into the housing portion 21. As a result, the torsion coil spring 40 biases the arm 30 so that it enters the housing portion 21. The torsion coil spring 40 also biases the guided boss 32A toward the outer circumferential surface of the housing portion 21.

[0041] [Effect] As shown in Figure 6, the arm 30, biased inward within the housing 21, first brings the guided boss 32A into contact with the upper end of the guide surface 23A and the outer circumferential surface of the housing 21 before an article is placed in the housing 21. The arm 30, also biased inward within the housing 21, brings the locking wall 32 into contact with the outer circumferential surface of the housing 21. Thus, the movement of the arm 30 relative to the housing 21 is restricted by the guide surface 23A and the outer circumferential surface of the housing 21. The movement of the shaft 22 relative to the operating part 35A is also restricted by the guide surface 23A and the outer circumferential surface of the housing 21. The shaft 22 of the holder 20 is located at the lower part of the operating part 35A of the arm 30.

[0042] Next, when an article is placed in the storage section 21, the first driven inclined surface 31T that contacts the article receives a downward external force from the article. The downward external force acting on the first driven inclined surface 31T from the article acts to push down the portion of the first driven inclined surface 31T that is in contact with the article.

[0043] In this case, if the coefficient of friction of the article is small, such as when the article is prone to sliding against the first driven inclined surface 31T, the first driven inclined surface 31T is prone to sliding against the article. Therefore, when the coefficient of friction of the article is small, the first driven inclined surface 31T slides against the article against the biasing force of the torsion coil spring 40 so that the part that contacts the article is lower within the first driven inclined surface 31T. Furthermore, because the first driven inclined surface 31T slides against the article, an external force that pushes the article downward does not act in a way that pushes both the first driven inclined surface 31T and the article downward.

[0044] As a result, when the coefficient of friction of the article is small, the shaft 22 rotates within the actuation part 35A while maintaining its position relative to the actuation part 35A, as shown by the arrow in Figure 6. Then, the first driven inclined surface 31T slides against the article as it exits the housing part 21. The guided boss 32A of the arm 30 rotates around the shaft 22 and moves outward and upward from the upper end of the guide surface 23A.

[0045] On the other hand, when the coefficient of friction of an article is high, such as when the article is not likely to slip against the first driven inclined surface 31T, the first driven inclined surface 31T is not likely to slide against the article. Therefore, while the movement of the part that contacts the article is suppressed within the first driven inclined surface 31T, a downward external force moves the first driven inclined surface 31T together with the article so that the part is lowered against the biasing force of the torsion coil spring 40. At this time, the actuating part 35A into which the shaft portion 22 is inserted has a shape that allows not only rotation of the shaft portion 22 relative to the actuating part 35A, but also translation of the shaft portion 22 relative to the actuating part 35A.

[0046] As a result, when the coefficient of friction of the article is large, as shown by the arrow in Figure 7, the external force pushing the article downward causes the guided boss 32A to move outward and downward along the guide surface 23A, pushing down both the first driven inclined surface 31T and the article. Then, the first driven inclined surface 31T exits the housing section 21 while moving outward and downward in parallel with sliding against the article.

[0047] [effect] According to the above embodiment, the following effects can be obtained. (1) Whether the coefficient of friction of the articles is small or large, the article holding device 10 can smoothly accommodate the articles.

[0048] (2) The holder 20 links the rotation and translation of the shaft 22 relative to the operating part 35A with the movement of the guided boss 32A along the guide surface 23A. As a result, the amount of translation and rotation of the shaft 22 relative to the operating part 35A is reproduced by the movement of the guided boss 32A along the guide surface 23A. As a result, the article holding device 10 can achieve reproducibility in the posture of the arm 30 when withdrawn.

[0049] (3) Because the guide surface 23A extends outward and downward from the housing portion 21, the movement of the guided boss 32A along the guide surface 23A, and consequently the translation and rotation of the shaft portion 22 relative to the operating portion 35A, are smoothly advanced by a downward external force.

[0050] (4) Since the guided boss 32A is a projection extending from the side of the arm 30, it is easy to assemble the guided boss 32A onto the guide surface 23A. (5) The torsion coil spring 40 that biases the arm 30 inward suppresses the translation of the shaft portion 22 relative to the operating portion 35A. Therefore, compared to a configuration in which a member that biases the arm 30 inward and a member that suppresses the translation of the shaft portion 22 are provided separately, it is possible to reduce the number of components that the article holding device 10 is equipped with.

[0051] (6) The mounting portion 35B for inserting the shaft portion 22 into the operating portion 35A extends in a direction different from the direction in which the operating portion 35A extends. This also helps to prevent the shaft portion 22 from coming off the operating portion 35A.

[0052] (7) The mounting portion 35B has an opening at the end opposite to the end connected to the operating portion 35A through which the shaft portion 22 passes. This makes it easier to assemble the shaft portion 22 to the operating portion 35A. In addition, the method for attaching the shaft portion 22 to the bearing portion 35 is easily grasped by the worker's intuition.

[0053] The above embodiment can also be implemented with the following modifications. [Guide member] The article holding device 10 may omit the guide portion from the holder 20 and provide a guided portion to the holder 20, and omit the guided portion from the arm 30 and provide a guide portion to the arm 30. For example, the arm 30 may have a guide surface 23A extending outward and downward, and the holder 20 may have a guided boss 32A protruding below the guide surface 23A. The article holding device 10 may then link the movement of the shaft portion 22 relative to the operating portion 35A to the relative movement of the guided boss 32A of the holder 20 along the guide surface 23A of the arm 30. In this case, one torsion coil spring 40 may be provided for each shaft portion 22.

[0054] The guide surface 23A may have an arc shape when viewed from the direction in which the shaft portion 22 extends. In this case, the guide surface 23A may also have a curved shape that protrudes downward. The article holding device 10 may omit at least one of the guide surface 23A and the guided boss 32A. In this case, the movement of the arm 30 relative to the housing 21 may be restricted by the movement of the shaft 22 relative to the operating part 35A.

[0055] [Bearing portion 35] The article holding device 10 may omit the shaft portion 22 from the holder 20 and provide a bearing portion 35 on the holder 20, and omit the bearing portion 35 from the arm 30 and provide a shaft portion 22 on the arm 30. For example, the support wall 21W of the holder 20 may have an operating portion 35A, and the arm 30 may have a shaft portion 22 that protrudes from the side toward the support wall 21W.

[0056] The operating part 35A may have a curved shape that extends outward and downward. In this case, the operating part 35A may also have a curved shape that protrudes downward. The mounting part 35B may have a linear shape that extends tangentially at the lower end of the operating part 35A.

[0057] The operating part 35A may have a linear shape extending parallel to the guide surface 23A. In this case, the movement of the shaft 22 with respect to the operating part 35A, accompanied by translation of the shaft 22, may be movement along the guide surface 23A and may be translation only, without rotation.

[0058] The mounting portion 35B may have a curved shape, and the operating portion 35A may have a linear shape extending tangentially at the end of the mounting portion 35B. The mounting portion 35B may be a bottomed groove that does not penetrate the locking wall 32. The operating portion 35A may be a bottomed groove that does not penetrate the locking wall 32. The mounting portion 35B may be connected to the operating portion 35A in the direction in which the operating portion 35A extends. Furthermore, the bearing portion 35 may omit the mounting portion 35B.

[0059] [Article holding device 10] The biasing force that suppresses the translation of the shaft portion 22 relative to the actuation portion 35A may be driven by a biasing member other than the torsion coil spring 40. For example, the article holding device 10 may include a coil spring 40 that biases the shaft portion 22 toward the lower end of the actuation portion 35A.

[0060] The first driven inclined surface 31T may have a straight shape that extends inward and downward when viewed from the direction in which the shaft portion 22 extends. [Explanation of Symbols]
