The leg 38 is formed of a rubber-like elastic body such as synthetic rubber. The pedal body 26A is rotatable around the pivot 35. The pedal section 26 can be rotated by the user's foot pressing down from above to below. When the user releases the foot press, the pedal section 26 can be returned from below to its original upper position by the action of an elastic member 41 (spring) provided at the connection section 27.
[0022] The support structure 22 is integrally formed from a metal material such as steel. As shown in FIG. 7, the support structure 22 has a frame portion 42 formed with a diameter larger than that of the support frame 21 and having a substantially C-shaped cross section, a support shaft 28 passed through an upper through hole of the frame portion 42, an insertion portion 43 provided integrally with the frame portion 42 at the lower portion of the frame portion 42 and having a U-shaped cross section, a groove portion 44 provided at the lower portion of the insertion portion 43, a fixing piece 45 inserted into the groove portion 44 and fixed, and a pair of guide rails 46 with a substantially U-shaped cross section fixed to the outer side surface of the frame portion 42. The fixing piece 45 is formed in a flat plate shape and has a notch portion 45A in the center for passing the rod-shaped connecting portion 27 and the lower end of the elastic member 41. The fixing piece 45 can support the lower side of the elastic member 41 (spring) of the connecting portion 27. The fixing piece 45 can hold the lower end of the elastic member 41 by, for example, sandwiching it between the connection portion 27 and an edge portion that defines the notch portion 45A. The support shaft 28 is fixed to the frame portion 42 by fixing means such as a screw.
[0023] The insertion portion 43 is formed with a smaller diameter than the frame portion 42 and a U-shaped cross section, and can be inserted tightly inside the support frame 21. Therefore, by inserting the insertion portion 43 into the upper end portion of the frame portion 42, the support structure 22 is firmly fixed to the support frame 21.
[0024] The guide rail 46 is fixed at an angle to the longitudinal direction (vertical direction) of the frame portion 42. The guide rail 46 is fixed to the outside of the frame portion 42 by, for example, welding. The support structure 22 has a guide piece 47 in which a guide groove 47A for guiding the support pin 72 of the rod portion 32 is formed on the inside of the guide rail 46. The guide piece 47 is made of a low-friction resin such as polyacetal. The guide piece 47 is fitted into the inside of the guide rail 46 and fixed.
[0025] As shown in Fig. 8, the lever portion 31 has a crank-like (S-shaped) overall shape. The lever portion 31 has a lever body 31A, a pair of flat metal plates 39 covering both sides (front and back) of the lever body 31A, a hole portion 51 provided in the lever body 31A for passing the support shaft 28 through, an input portion 52 (first long hole portion) provided in the lever body 31A and connected to the other end of the connection portion 27, an action portion 53 (second long hole portion) provided in the lever body 31A and connected to the rod portion 32, and a slit portion 54 formed in the vicinity of the input portion 52. The lever portion 31 is rotatable around the support shaft 28. The metal plates 39 are formed of a metal material such as steel.
[0026] The lever body 31A is integrally molded from a low-friction resin such as polyacetal. The outer periphery 55 protrudes in the thickness direction from the lever body 31A and is formed to be at the same height as the surface formed by the metal plate 39. Therefore, even if the lever body 31A (outer periphery 55) comes into contact with a peripheral member, the generation of abnormal noise or the like between them during operation of the lever part 31 is prevented.
[0027] Hole 51 is provided at one end of lever 31. Hole 51 has cylindrical adapter parts 56 on both sides (front and back) that protrude so as to penetrate through a through hole formed in metal sheet 39. Adapter parts 56 are molded integrally with lever body 31A.
[0028] The input portion 52 is provided at approximately the middle of the lever portion 31. The through hole constituting the input portion 52 is divided by a slit portion 54 formed at the middle portion in the thickness direction of the lever portion 31. In addition, an edge portion 57 defining the inner peripheral surface of the input portion 52 protrudes from the lever main body 31A in the thickness direction and passes through a through hole formed in the metal plate 39. The edge portion 57 defining the inner peripheral surface of the input portion 52 is formed to be at the same height as the surface formed by the metal plate 39.
[0029] The action portion 53 is provided at a position farther from the spindle 28 and the hole portion 51 through which the spindle 28 passes than the input portion 52. In other words, the action portion 53 is provided at the other end opposite to the one end of the lever portion 31. The action portion 53 has an oval cylindrical second adaptor portion 61 on both sides (front and back) that protrudes so as to penetrate a through hole formed in the metal plate 39. The second adaptor portion 61 is molded integrally with the lever main body 31A.

The elastic member 41 is formed of, for example, a compression coil spring.
[0031] The first fixing member 64 is formed of a screw and a nut, and is fixed to the long fixing hole 37 of the pedal portion 26. The insertion piece 65 can be inserted into the inside of the slit portion 54 of the lever portion 31. The second fixing member 66 is formed of a screw and a nut, and can fix the other end of the connection portion 27 to the input portion 52 of the lever portion 31.
[0032] The rod portion 32 can move forward and backward in the thickness direction of the lid body 23 at the first position P1 between a third position P3 where the rod portion 32 is retracted from the lid body 23 and a fourth position P4 where the rod portion 32 abuts against the lid body 23 from the inside and moves the lid body 23 from the first position P1 to the second position P2. As shown in FIG. 10, the rod portion 32 has a rod main body 32A formed by bending a long and thin metal plate into a U-shape, a cylindrical pin 67 that is passed through the action portion 53 of the lever portion 31 and fixed to the rod main body 32A by a screw or the like, a pair of rollers 68 rotatably provided at the tip of the rod main body 32A, a flange portion 71 provided on the base side of the rollers 68, and a support pin 72 that rotatably supports the rollers 68. The rod main body 32A is formed of a metal material such as steel.
[0033] The roller 68 can abut against the abutment portion 76 of the bracket 73 with its outer circumferential surface. The roller 68 is formed of a low-friction resin such as polyacetal. The flange portion 71 is provided on the base side of the roller 68 and is molded integrally with the roller 68. The flange portion 71 is formed in a flat plate shape with a diameter larger than that of the roller 68. When the cover body 23 and the second cover body 24 move in the lateral direction, the flange portion 71 engages with the bracket 73 which moves in the lateral direction in conjunction with the movement, and can prevent the bracket 73 from falling off the roller 68.
[0034] Each of the pair of lids 23 is formed in a flat plate shape from a metal material such as steel. As shown in Figs. 5 and 6, the lid 23 is provided so as to close the lower side of the opening 16. The lid 23 is rotatable between a first position P1 in which the opening 16 is closed and a second position P2 in which the opening 16 is opened. The lid 23 includes a lid body 23A, a pair of brackets 73 fixed to both sides of the lid body 23A, and a rotating shaft 74 that rotatably supports the lid body 23A and the bracket 73. The bracket 73 is fixed to the lid body 23A by screws, welding, or the like. The lid body 23A protrudes from the rotating shaft 34 toward the opening 16. The lid 23 and the second lid 24 open and close in an inward opening manner. Therefore, the lid body 23A is located inside the main body 12 when it is in the second position P2. The rotating shaft 74 is fixed to the main body 12 by welding, or the like.
[0035] Each of the pair of brackets 73 has a fixed portion 75 fixed to the lid 23, a contact portion 76 extending from the fixed portion 75 like an arm and against which the roller 68 of the rod portion 32 abuts, and a first fixed portion 77 provided at the tip of the contact portion 76 and fixed to the first end portion 33A of the link portion 33 by a screw, a pin, or the like. The contact portion 76 is provided on the opposite side to the lid body 23A. The contact portion 76 protrudes from the rotation shaft 74 by a dimension smaller than the dimension by which the lid body 23A protrudes from the rotation shaft 74. More specifically, the contact portion 76 is located in the vicinity of the rotation shaft 74.
[0036] Each of the pair of second lid bodies 24 is formed into a flat plate shape from a metal material such as steel. As shown in Figs. 5 and 6, the second lid body 24 is provided adjacent to the lid body 23 so as to close the upper side of the opening 16. The second lid body 24 is rotatable between a fifth position P5 where the opening 16 is closed and a sixth position P6 where the opening 16 is opened. The second lid body 24 is configured to have an area larger than the area of the lid body 23.
[0037] The second lid body 24 includes a second lid body main body 24A, a concealing portion 29 extending from the tip of the second lid body main body 24A toward the inside of the main body 12, a pair of second brackets 81 fixed to both sides of the second lid body main body 24A, and a second rotating shaft 78 that rotatably supports the second lid body main body 24A and the second bracket 81. The second rotating shaft 78 is fixed to the main body 12 by welding or the like. The second lid body 24 is rotatable around the second rotating shaft 78 provided on the opposite side of the rotating shaft 74 of the lid body 23 across the opening 16. The concealing portion 29 prevents the inside of the trash can 11 from being seen from between the lid body 23 and the second lid body 24. The concealing portion 29 also prevents the user's fingers or trash from getting caught in the second lid body 24.
[0038] Each of the pair of second brackets 81 is fixed to the second cover 24 by screws, welding, or the like. The second bracket 81 has a second fixing portion 82 that is fixed to the second end 33B of the link portion 33 by a screw, a pin, or the like.
[0039] The link portion 33 is provided in a pair on both sides of the lid body 23 and the second lid body 24. Each of the pair of link portions 33 has a first end portion 33A connected to the bracket 73 and a second end portion 33B connected to the second bracket 81. The link portion 33 connects the lid body 23 and the second lid body 24. The link portion 33 rotates the second lid body 24 between a fifth position P5 where the opening 16 is closed and a sixth position P6 where the opening 16 is opened, so as to move in conjunction with the movement of the lid body 23 from the first position P1 to the second position P2. In addition, at that time, the link portion 33 connects the lid body 23 and the second lid body 24 so that the rotation direction of the second lid body 24 from the fifth position P5 to the sixth position P6 is opposite to the rotation direction of the lid body 23 from the first position P1 to the second position P2. Therefore, the cover 23 and the second cover 24 can be opened and closed in a double door manner.
[0040] Next, an assembly method for the support structure 22 and the pedal portion 26 of the trash can 11 of this embodiment will be described. Prior to mounting the support structure 22, the frame 15 and the overhanging portion 18 are, for example, screwed or welded to the main body 12 of the trash can 11, and the lid 23, the second lid 24, and the link portion 33 are attached to the frame 15 by screwing or the like. In addition, the support frame 21 is fixed to the main body 12 and the overhanging portion 18 of the trash can 11 by welding or the like.
[0041] The pedal fixing part 25 is fixed to the lower part of the vertically extending part of the support frame 21 by means of screws or the like. The pedal part 26 is fixed to this pedal fixing part 25 by means of a pivot 35 (screw). Furthermore, the rod-shaped connecting part 27 is passed through the inside of the vertically extending part of the support frame 21. One end of the connecting part 27 is fixed to the pedal part 26 by means of a first fixing member 64.
[0042] Next, the support structure 22 is fixed to the upper end of the vertically extending portion of the support frame 21. At this time, the lever portion 31 and the rod portion 32 are attached to the support structure 22 in advance. Specifically, the lever portion 31 is attached to the support structure 22 by passing the support shaft 28 (screw) through the hole portion 51 of the lever portion 31. The rod portion 32 is attached to the guide rail 46 of the support structure 22. The roller 68, which is integrated with the flange portion 71, is attached to the rod portion 32 in advance via the support pin 72. When the rod portion 32 is attached to the guide rail 46, the support pin 72 is fitted into the guide groove 47A of the guide piece 47. This prevents the rod portion 32 from falling off the guide rail 46. Furthermore, the rod portion 32 is attached to the action portion 53 of the lever portion 31 via the pin 67 (screw). In this manner, with the lever portion 31 and the rod portion 32 attached to the support structure 22 in advance, the insertion portion 43 of the support structure 22 is inserted into the frame portion 42.
[0043] The insertion piece 65 at the other end of the connection part 27 is inserted into the slit part 54 of the lever part 31 positioned in the support structure 22. In this state, the second fixing member 66 is passed through the input part 52 of the lever part 31 and the through hole of the insertion piece 65 of the connection part 27 to fix the lever part 31 and the connection part 27. Furthermore, the fixing piece 45 is inserted into the groove part 44 of the support structure 22. At that time, the shaft part 62 of the connection part 27 is passed through the notch part 45A. As a result, the lower end of the elastic member 41 is supported by the fixing piece 45, and the pedal part 26 can be urged to be pulled up by the urging force of the elastic member 41. Similarly, the rod part 32 is held in the third position P3 retracted from the cover body 23 by the urging force of the elastic member 41. The above steps complete the assembly of the support structure 22 and the pedal part 26 to the main body 12.
[0044] Next, the operation of the trash can 11 of this embodiment will be described with reference to FIGS.
[0045] When the user depresses the pedal portion 26 from the initial position shown in FIG. 5 by stepping on it, the pedal portion 26 rotates downward as shown in FIG. 11. When the stepping angle is large, the leg portion 38 of the pedal portion 26 abuts against the floor surface, stopping the rotation of the pedal portion 26. As the pedal portion 26 rotates downward, the elastic member 41 is compressed and the connection portion 27 moves downward. As the connection portion 27 moves downward, tension from the connection portion 27 acts on the input portion 52 of the lever portion 31. This causes the lever portion 31 to rotate about the support shaft 28 from the seventh position P7 shown in FIG. 5 to the eighth position P8 shown in FIG. 11. As a result, the rod portion 32 connected to the action portion 53 of the lever portion 31 is pushed out from the third position P3 where it is retracted from the cover body 23 as shown in FIG. 5 in a direction approaching the cover body 23, and moves to the fourth position P4 where it abuts against the cover body 23 as shown in FIG. 11. At that time, the roller 68 located at the tip of the rod portion 32 abuts against the abutment portion 76 of the bracket 73 of the lid body 23. As the rod portion 32 advances, the abutment portion 76 is pushed forward, and the lid body 23 rotates around the rotation shaft 74. As a result, the lid body 23 moves from the first position P1 where the opening 16 is closed to the second position P2 where the opening 16 is opened. As the lid body 23 rotates from the first position P1 to the second position P2, the link portion 33 transmits this rotational force to the second lid body 24. That is, as the lid body 23 rotates, the link portion 33 is pushed upward while moving forward. Due to this movement of the link portion 33, the second bracket 81 rotates backward (inside the main body 12), and the second lid body 24 moves from the fifth position P5 where the opening 16 is closed as shown in FIG. 5 to the sixth position P6 where the opening 16 is opened by rotating toward the inside of the main body 12 as shown in FIG. 11. In this manner, the opening operation of the lid body 23 and the second lid body 24 performed by stepping on the pedal portion 26 is completed.
[0046] At this time, since the action part 53 is provided at a position farther from the support shaft 28 than the input part 52, the amount of operating force when advancing the rod part 32 via the action part 53 is reduced by the principle of leverage, and the distance that the action part 53 moves with rotation is lengthened, thereby ensuring a sufficient amount of advancement and retreat of the rod part 32. Also, since the abutment part 76 of the lid body 23 is provided near the rotation shaft 74, a sufficiently large rotation angle of the lid body main body 23A can be obtained by moving the abutment part 76 a small distance.
[0047] When the user releases the pedal portion 26, the repulsive force of the elastic member 41 lifts the connection portion 27 upward, and the pedal portion 26 also returns to the initial position. At the same time, the lever portion 31 returns from the eighth position P8 to the seventh position P7, and the rod portion 32 is accordingly moved backward from the fourth position P4 to the third position P3. The backward movement of the rod portion 32 causes the second cover body 24 to rotate from the sixth position P6 to the fifth position P5 due to its own weight. Accordingly, the link portion 33 transmits the rotational force of the second cover body 24 to the cover body 23, so that the cover body 23 returns from the second position P2 to the first position P1. In this way, by releasing the pedal portion 26, the cover body 23 and the second cover body 24 return to a state in which they close the opening 16.
[0048] In addition, the user can rotate the lid body 23 and the second lid body 24 by using his / her fingers or dust, without stepping on the pedal portion 26. That is, when the user does not step on the pedal portion 26, the rod portion 32 is held in the third position P3 retracted from the lid body 23, as shown in Figs. 5 and 12. Therefore, the lid body 23 and the second lid body 24, which moves in conjunction with the lid body 23 via the link portion 33, can be freely rotated from the first position P1 to the second position P2 (the second lid body 24 can also be rotated from the fifth position P5 to the sixth position P6) by being pushed in by the user's fingers or dust without receiving resistance from the rod portion 32. Therefore, even if the pedal portion 26 for stepping on is provided, the power transmission system 34 including the pedal portion 26, the connection portion 27, the lever portion 31, and the rod portion 32 does not become a load when the user opens and closes the lid body 23 without using the pedal portion 26. In this way, the user can rotate lid body 23 and second lid body 24 with a light force even when rotating them without using pedal portion 26. As described above, in both cases where lid body 23 and second lid body 24 are rotated using pedal portion 26 and where lid body 23 and second lid body 24 are rotated without using pedal portion 26, the amount of operating force required by the user to rotate lid body 23 and second lid body 24 is reduced, thereby realizing a user-friendly trash can 11.
[0049] According to this embodiment, the following can be said: The trash can 11 comprises a main body 12 having an opening 16, a lid 23 rotatable between a first position P1 in which the opening 16 is closed and a second position P2 in which the opening 16 is open, a foot-operated pedal section 26 for moving the lid 23 between the first position P1 and the second position P2, a connection section 27 connected at one end to the pedal section 26, and a lever section 31 rotatable about a support shaft 28, the other end of which is connected to the connection section 27 opposite to the one end. The lever portion 31 has an input portion 52 disposed in a position farther from the support shaft 28 than the input portion 52, and an action portion 53 disposed in a position farther from the support shaft 28 than the input portion 52, and a rod portion 32 connected to the action portion 53 and capable of advancing and retreating in accordance with the rotation of the lever portion 31 in the thickness direction of the lid body 23 located at the first position P1 between a third position P3 retracted from the lid body 23 and a fourth position P4 where the rod portion 32 abuts against the lid body 23 from the inside and moves the lid body 23 from the first position P1 to the second position P2.
[0050] According to this configuration, by stepping on the pedal portion 26, the lid body 23 can be moved between the first position P1 and the second position P2 without touching the lid body 23. This prevents the user from having to touch the lid body 23 to open or close the lid body 23, and prevents the spread of infectious diseases (e.g., coronavirus infection) due to contact. In addition, since the action portion 53 of the lever portion 31 is provided at a position farther away from the support shaft 28 than the input portion 52, the amount of movement of the action portion 53 can be increased when the lever portion 31 rotates around the support shaft 28 by the principle of leverage, and the amount of force required to move the rod portion 32 forward and backward at the action portion 53 can be reduced. This ensures a sufficient amount of forward and backward stroke of the rod portion 32, making it possible to sufficiently increase the angle of the second position P2 of the lid body 23 relative to the first position P1 of the lid body 23 and ensure a large opening and closing stroke of the lid body 23. In addition, the amount of force required to step on the pedal portion 26 can be reduced. These features improve the convenience of the user. Furthermore, when the rod portion 32 is in the third position P3 retracted from the lid body 23, the user can rotate the lid body 23 by hand as necessary. At that time, because the rod portion 32 is in the third position P3 retracted from the lid body 23, the structure of the rod portion 32, the lever portion 31, the connection portion 27, and the pedal portion 26 does not provide resistance to the user rotating the lid body 23 by hand. Therefore, the amount of operating force required to rotate the lid body 23 by hand can be reduced.
[0051] In this case, the lid body 23 comprises a rotation axis 74 that serves as the center of rotation when rotating between the first position P1 and the second position P2, a lid body main body 23A protruding from the rotation axis 74 toward the opening 16, and an abutment portion provided on the opposite side of the lid body main body 23A, protruding from the rotation axis 74 by a dimension smaller than the dimension by which the lid body main body 23A protrudes from the rotation axis 74, and against which the rod portion 32 or the second rod portion 91 abuts.
[0052] According to this configuration, by using the principle of leverage, not only can the stroke of the rod portion 32 (second rod portion 91 described in the second embodiment) required for rotation of the abutment portion 76 be minimized, but also the rotation stroke of the lid body main body 23A that rotates with the rotation of the abutment portion 76 can be maximized. This ensures a sufficient rotation stroke of the lid body main body 23A, and does not cause a situation in which the rotation angle of the lid body 23 is insufficient, making it difficult to use. This makes it possible to realize a trash can 11 that is easy for the user to use.
[0053] In this case, the abutment portion 76 is located near the rotation shaft 74. This configuration can minimize the protruding dimension of the abutment portion 76. This makes it possible to minimize the stroke of the rod portion 32 required for rotation of the abutment portion 76, and to maximize the rotation stroke of the lid body 23A that rotates in conjunction with the rotation of the abutment portion 76.
[0054] In this case, the rod portion 32 or the second rod portion 91 has a roller 68 at a position where it abuts against the abutment portion 76. If the dimension by which the abutment portion 76 protrudes from the rotation shaft 74 is reduced, the installation angle of the abutment portion 76 will change suddenly as the lid body 23 rotates. With the above configuration, even if the angle of the abutment portion 76 changes suddenly as the lid body 23 rotates, the force of the rod portion 32 (the second rod portion 91 described in the second embodiment) that presses the lid body 23 can be efficiently transmitted to the lid body 23 via the roller 68. This allows the rotational movement of the lid body 23, which rotates as the rod portion 32 advances and retreats, to be smooth.
[0055] In this case, when the lid body 23A is in the second position P2, it is located inside the main body 12. With this configuration, when the lid body 23 is in the second position P2, it is possible to rotate the lid body 23 toward the inside of the main body 12. This prevents the lid body 23 from interfering with the user's garbage disposal operation.
[0056] In this case, the device includes a second cover body 24 provided adjacent to the cover body 23, the second cover body 24 being rotatable around a second rotation axis 78 provided on the opposite side of the rotation axis 74 across the opening 16, and a link portion 33 that connects the cover body 23 and the second cover body 24 and rotates the second cover body 24 between a fifth position P5 in which the opening 16 is closed and a sixth position P6 in which the opening 16 is opened, so as to move in conjunction with the cover body 23 when it moves from the first position P1 to the second position P2, and the rotation direction from the fifth position P5 to the sixth position P6 is opposite to the rotation direction of the cover body 23 from the first position P1 to the second position P2.
[0057] According to this configuration, the second lid body 24 can be rotated in conjunction with the lid body 23. Also, the rotation direction of the second lid body 24 from the fifth position P5 to the sixth position P6 can be made to be the opposite direction to the rotation direction of the lid body 23 from the first position P1 to the second position P2, so that the lid body 23 and the second lid body 24 can be opened in a so-called double door manner. This allows the opening 16 to be opened sufficiently large when the lid body 23 and the second lid body 24 are opened, improving user convenience.
[0058] In the following embodiment, differences from the first embodiment will be mainly described, and illustrations or descriptions of parts common to the first embodiment will be omitted. [Second embodiment]
[0059] A trash can 11 of the second embodiment will be described with reference to Figs. 13 to 16. The shape of the lever portion 31 of the trash can 11 of the second embodiment is different from that of the first embodiment. Furthermore, the trash can 11 of the second embodiment does not have the rod portion 32, and has a second rod portion 91 that is integral with the lever portion 31 instead of the rod portion 32. The support structure 22 does not have the guide rail 46 and the guide piece 47. The fixed piece 45 is formed integrally with the support structure 22.
[0060] 13 to 16, the lever portion 31 has a lever body 31A having a U-shaped cross section, a hole portion 51 provided in the lever body 31A for passing the spindle 28 through, an input portion 52 (first elongated hole portion) provided in the lever body 31A and connected to the other end of the connection portion 27, and a second rod portion 91 provided integrally with the lever body 31A. The lever portion 31 is rotatable about the spindle 28.
[0061] Lever body 31A is formed of a metal material such as steel. A pair of input portions 52 are provided at approximately the middle portion of lever portion 31. A first long hole portion constituting input portion 52 extends obliquely with respect to the longitudinal direction L of lever body 31A.
[0062] The second rod portion 91 is rotatable with the rotation of the lever portion 31 between a third position P3 where the second rod portion 91 is retracted from the cover body 23 and a fourth position P4 where the second rod portion 91 abuts against the cover body 23 from the inside and moves the cover body 23 from the first position P1 to the second position P2. The second rod portion 91 extends in a direction intersecting with the longitudinal direction L of the lever main body 31A, and protrudes from the lever main body 31A toward the cover body 23. In other words, the second rod portion 91 extends in a direction intersecting with the direction connecting the support shaft 28 and the input portion 52.
[0063] 15, the second rod portion 91 has a rod body 91A formed by bending a long and thin metal plate into a U-shape, a pair of rollers 68 rotatably provided at the tip of the rod body 91A, a flange portion 71 provided at the base side of the rollers 68, and a support pin (not shown) for rotatably supporting the rollers 68. The rod body 91A is formed of a metal material such as steel. The structures of the rollers 68, flange portion 71, and support pins of this embodiment are similar to the structures of the rollers 68, flange portion 71, and support pins 72 of the first embodiment.
[0064] Next, the operation of the trash can 11 of this embodiment will be described with reference to FIGS.
[0065] When the user depresses the pedal portion 26 from the initial position shown in FIG. 13 by stepping on it, the pedal portion 26 rotates downward as shown in FIG. 14. If the angle of depression is large, the leg portion 38 of the pedal portion 26 abuts against the floor surface, stopping the rotation of the pedal portion 26. As the pedal portion 26 rotates downward, the elastic member 41 is compressed and the connection portion 27 moves downward. As the connection portion 27 moves downward, tension from the connection portion 27 acts on the input portion 52 of the lever portion 31. This causes the lever portion 31 to rotate about the support shaft 28 from the seventh position P7 shown in FIGS. 13 and 15 to the eighth position P8 shown in FIGS. 14 and 16. Accordingly, the second rod portion 91 integrated with the lever portion 31 is pushed from the third position P3 retracted from the lid body 23 as shown in Figs. 13 and 15 in a direction approaching the lid body 23, and rotates to the fourth position P4 abutting against the lid body 23 as shown in Figs. 14 and 16. At that time, the roller 68 located at the tip of the second rod portion 91 abuts against the abutment portion 76 of the bracket 73 of the lid body 23. As the second rod portion 91 advances, the abutment portion 76 is pushed forward, and accordingly the lid body 23 rotates about the rotation shaft 74. As a result, the lid body 23 moves from the first position P1 where the opening 16 is closed to the second position P2 where the opening 16 is opened. As the lid body 23 rotates from the first position P1 to the second position P2, the link portion 33 transmits this rotational force to the second lid body 24. That is, as the lid body 23 rotates, the link part 33 is pushed upward while moving forward. This movement of the link part 33 causes the second bracket 81 to rotate rearward (toward the inside of the main body 12), and the second lid body 24 moves from a fifth position P5 where the second lid body 24 closes the opening 16 as shown in Figures 13 and 15 to a sixth position P6 where the second lid body 24 rotates toward the inside of the main body 12 and opens the opening 16 as shown in Figures 14 and 16. In this manner, the opening operation of the lid body 23 and the second lid body 24 performed by stepping on the pedal part 26 is completed.
[0066] When the user releases the pedal portion 26, the connection portion 27 is lifted upward by the repulsive force of the elastic member 41, and the pedal portion 26 also returns to the initial position. At the same time, the lever portion 31 returns from the eighth position P8 to the seventh position P7, and the second rod portion 91 is accordingly moved backward from the fourth position P4 to the third position P3. The second rod portion 91 is moved backward, and the second cover body 24 rotates from the sixth position P6 to the fifth position P5 due to its own weight. The link portion 33 accordingly transmits the rotational force of the second cover body 24 to the cover body 23, so that the cover body 23 returns from the second position P2 to the first position P1. In this way, by releasing the pedal portion 26, the cover body 23 and the second cover body 24 return to a state in which the opening 16 is closed.
[0067] In addition, the user can rotate the lid body 23 and the second lid body 24 by using his / her fingers or dust, without stepping on the pedal portion 26. That is, when the user does not step on the pedal portion 26, the rod portion 32 is held in the third position P3 retracted from the lid body 23, as shown in Figs. 13 and 15. Therefore, the lid body 23 and the second lid body 24, which moves in conjunction with the lid body 23 via the link portion 33, can be freely rotated from the first position P1 to the second position P2 (the second lid body 24 can also be rotated from the fifth position P5 to the sixth position P6) by being pushed in by the user's fingers or dust without receiving resistance from the rod portion 32. Therefore, even if the pedal portion 26 for stepping on is provided, the power transmission system 34 including the pedal portion 26, the connection portion 27, and the lever portion 31 does not become a load when the user opens and closes the lid body 23 without using the pedal portion 26. In this way, the user can rotate lid body 23 and second lid body 24 with a light force even when rotating them without using pedal portion 26. As described above, in both cases where lid body 23 and second lid body 24 are rotated using pedal portion 26 and where lid body 23 and second lid body 24 are rotated without using pedal portion 26, the amount of operating force required by the user to rotate lid body 23 and second lid body 24 is reduced, thereby realizing a user-friendly trash can 11.
[0068] According to this embodiment, the following can be said: The trash can 11 includes a main body 12 having an opening 16, a lid body 23 rotatable between a first position P1 where the opening 16 is closed and a second position P2 where the opening 16 is open, a foot-operated pedal unit 26 for moving the lid body 23 between the first position P1 and the second position P2, a connection unit 27 connected at one end to the pedal unit 26, a lever unit 31 rotatable about a support shaft 28 and having an input unit 52 connected to the other end opposite to the one end of the connection unit 27, and a second rod unit 91 extending in a direction intersecting a direction connecting the support shaft 28 and the input unit 52, the second rod unit 91 rotating with the rotation of the lever unit 31 between a third position P3 where the lid body 23 is retracted and a fourth position P4 where the lid body 23 is abutted from the inside to move the lid body 23 from the first position P1 to the second position P2.
[0069] According to this configuration, the second rod portion 91 can be provided as a part of the lever portion 31. This allows the number of parts to be reduced compared to the first embodiment, and the manufacturing costs of the trash can to be reduced.
[0070] The above-described embodiment can be implemented with various substitutions and modifications. In the first embodiment, the abutment portion 76 and the rod portion 32 are formed separately, but the abutment portion 76 and the rod portion 32 may be formed integrally. In this case, when a user tries to open the lid body 23 with his / her hand or the trash itself, the lid body 23 receives resistance due to friction generated in the power transmission system 34, but the number of parts can be reduced. Similarly, in the second embodiment, the abutment portion 76 and the second rod portion 91 are formed separately, but the abutment portion 76 and the second rod portion 91 may be formed integrally. In this case, when a user tries to open the lid body 23 with his / her hand or the trash itself, the lid body 23 receives resistance due to friction generated in the power transmission system 34, but the number of parts can be reduced. In addition, the first and second embodiments can of course be combined appropriately to configure the invention as desired. [Explanation of symbols]
