  As shown in FIG. 3, the gear member 35 is a cylindrical body, and includes a pinion gear 35 a provided in the circumferential direction at the outer end, and a fitting hole 35 b penetrating in the axial direction of the gear member 35. The tip of the transmission shaft 34 is fitted into the fitting hole 35b. In this way, the gear member 35 is integrally fixed to both ends of the transmission shaft 34. Since the pinion gears 35a provided in the pair of gear members 35 have the same number of teeth, they rotate in synchronization with each other.

  A pair of holding portions 21, 21 project from the portion of the tray 2 that faces the first groove 12 a. Each holding part 21 has a bearing hole 21a. A gear member 35 is rotatably inserted into the bearing hole 21a. As shown in FIG. 6, the pinion gear 35a at the tip of the gear member 35 meshes with the rack gear 31 of the first groove portion 12a. As the tray 2 moves up and down, the pinion gear 35 a moves up and down along the rack gear 31.

The guide protrusion 22 protrudes radially outward from the holding portion 21 and has a pair of tray-side facing surfaces 22a. The pair of tray-side facing surfaces 22a are provided on both the left and right sides of the guide protrusion 22 in the circumferential direction, and each extend in the vertical direction.

  As shown in FIGS. 5 and 7, the guide protrusion 22 is fitted to the rack member 15 disposed in the first groove 12a so as to be movable up and down. The pair of side walls 16, 16 of the rack member 15 have groove-side facing surfaces 16 a, 16 a that are located on the back side of the rack gear 31 and face each other in the circumferential direction of the accommodation space 10. The guide protrusion 22 of the tray 2 is inserted into the rack member 15 in the first groove 12a, and the tray-side facing surfaces 22a and 22a face the groove-side facing surfaces 16a and 16a. Each tray-side facing surface 22a, 22a faces each groove-side facing surface 16a, 16a and has a shape corresponding to the shape of the groove-side facing surfaces 16a, 16a. In the present embodiment, the groove facing surfaces 16a and 16a and the tray facing surfaces 22a and 22a are all flat surfaces extending in the vertical direction.

  As shown in FIG. 7, the guide protrusion 22 is sandwiched between the pair of groove-side facing surfaces 16a and 16a in a state of surface contact with the groove-side facing surfaces 16a and 16a in the pair of tray-side facing surfaces 22a. The pair of groove-side facing surfaces 16a and 16a receive a load applied to the tray 2 and maintain the tray 2 in the horizontal direction. When the tray 2 is moved in the vertical direction, the pinion gear 35a moves along the rack gear 31, and the tray-side facing surface 22a of the tray 2 slides on the groove-side facing surfaces 16a, 16a of the first groove portion 12a. Since the guide protrusions 22 are disposed in the first groove 12a in a state where the pair of tray-side facing surfaces 22a are in surface contact with the pair of groove-side facing surfaces 16a, the tray 2 is wobbled with respect to the holder body 1.

  As shown in FIGS. 3 and 7, a plate-like protrusion 23 is provided on the periphery of the tray 2 and immediately above the guide protrusion 22. The protrusion 23 is inserted into the first groove 12a together with the guide protrusion 22, and is sandwiched between the groove-side facing surfaces 16a and 16a of the first groove 12a. The protrusion 23 secures a certain gap between the peripheral edge of the tray 2 and the peripheral wall 11 of the holder body 1 to prevent the tray 2 from interfering with the peripheral wall 11. For this reason, the tray 2 can be smoothly moved up and down.

  As shown in FIGS. 2 and 3, the urging member 33 is a coil spring and is attached to the outside of a cylindrical collar 36 that passes through the transmission shaft 34. One end of the urging member 33 is fitted to a pin 34 b protruding from the transmission shaft 34, and the other end of the urging member 33 is connected to the lower surface of the tray 2. The urging member 33 urges the transmission shaft 34 in the direction in which the tray 2 moves upward. In the present embodiment, the urging member 33 urges the transmission shaft 34 in the clockwise rotation direction (clockwise direction). As the transmission shaft 34 rotates in the clockwise direction, the pinion gear 35 a moves upward while rotating along the rack gear 31. Thereby, the tray 2 is moved upward.

  A speed buffer device 37 is provided at the bottom of the tray 2. The speed buffer device 37 includes a fixed portion 37a, a rotating portion 37b that is rotatable with respect to the fixed portion 37a, and a viscous liquid interposed between the fixed portion 37a and the rotating portion 37b. The fixing portion 37a of the speed buffer 37 is fixed to the mounting portion 24 protruding downward from the lower surface of the tray 2 with a screw (FIG. 2). A gear 37c is provided at the tip of the rotating portion 37b. A transmission gear 38 is inserted into the transmission shaft 34 and fixed integrally therewith.

  The transmission gear 38 meshes with the gear 37c of the speed buffer 37. When the transmission shaft 34 rotates, the transmission gear 38 rotates synchronously. When the transmission gear 38 rotates, the gear 37c of the speed buffer 37 is rotated. The gear 37c is subjected to resistance by the viscous liquid in the speed buffer 37, and a sudden change in the rotational speed is alleviated. The rotational speed of the gear 37c is relaxed, and a rapid speed change of the transmission shaft 34 is suppressed. When the transmission shaft 34 is about to increase its rotational speed abruptly by the biasing member 33, the rapid increase in rotational speed is alleviated by the speed buffer 37.

  As shown in FIG. 8, the operation unit 6 includes a knob 62, a case 63, a support shaft 64, and an operation rod 65. The operation portion 6 is disposed outside the peripheral wall 11 of the holder body 1 and in the vicinity of the second groove portion 12b (FIG. 4). The knob 62 includes a pressing portion 62a, a sliding portion 62b protruding from the pressing portion 62a, a fitting hole 62c formed in the sliding portion 62b and penetrating in the vertical direction, and play holes formed on both side surfaces of the sliding portion 62b. 62d. The knob 62 is disposed in an operation hole 11c formed in the peripheral wall 11 of the holder body 1 so as to be able to advance and retract (FIG. 5). The pressing portion 62a of the knob 62 is exposed to the accommodation space 10 side from the operation hole 11c, and the slide portion 62b is directed to the outside of the peripheral wall 11.

  The play hole 62d is a guide hole that is inclined upward in the direction away from the accommodation space 10 (outside in the radial direction of the holder body 1). The case 63 includes a cylindrical housing portion 63a into which the slide portion 62b of the knob 62 is inserted so as to be able to advance and retreat, an insertion hole 63b that penetrates the housing portion 63a in the vertical direction, and a flange portion 63c that spreads outside the housing portion 63a. Have. Long holes 63d extending in the vertical direction are formed on the side surfaces on both sides of the accommodating portion 63a. A spring 66 is interposed between the inner surface of the slide portion 62 b of the knob 62 and the inner surface of the housing portion 63 a of the case 63. The spring 66 is externally inserted into a spring holding portion 62 e that protrudes from the rear surface of the knob 62. By the spring 66, the knob 62 is urged in a direction to advance from the operation hole 11c of the holder body 1 toward the accommodation space 10 side.

  The operating rod 65 includes a long portion 65b, a connecting portion 65c having a narrow width on the upper side of the long portion 65b, and a support hole 65d provided in the connecting portion 65c. A thin cylindrical spring holding portion 65e is provided from the lower portion of the operation rod 65.

The return spring 67 is a compression coil spring, and is disposed between the outer peripheral edge of the bottom plate 8 of the holder body 1 and the lower portion of the operation rod 65, and urges the operation rod 65 upward.

  The balance of the urging force of the return spring 67 and the lock urging member 56 is such that the rocking force of the lock member 51 generated by the lock urging member 56 is smaller than the return force to the upper side of the regulating portion 61 generated by the return spring 67. Is set to

  In order to assemble the operation portion 6, the slide portion 62 b of the knob 62 is accommodated in the accommodation portion 63 a of the case 63. The connecting portion 65 c of the operation rod 65 is inserted into the insertion hole 63 b of the case 63. The support shaft 64 is inserted into the play hole 62d of the slide portion 62b, the elongated hole 63d of the accommodating portion 63a, and the support hole 65d of the operating rod 65. A retaining ring (not shown) is fitted to both ends of the support shaft 64 in order to prevent it from coming off. Thereby, the knob 62, the case 63, the operation rod 65, and the support shaft 64 are integrated, and the operation part 6 is obtained.

  As shown in FIG. 9, a restricting portion 61 is provided below the operation rod 65. The restricting portion 61 protrudes rearward from the lower portion of the operation rod 65. The lower surface of the restricting portion 61 has a tapered surface 61a that is inclined upward toward the tip. The operation rod 65 is disposed in the vicinity of the left groove portion of the second groove portion 12 b outside the peripheral wall 11 of the holder body 1.

  The left and right groove portions (in this embodiment, the left groove portion) of the second groove portion 12b are provided with an insertion hole 12c in the lower portion thereof. The insertion hole 12c is formed continuously to one side wall 13 and the back wall 14 of the side walls facing each other of the second groove portion 12b.

  The restricting unit 61 is configured to be displaced in the vertical direction by the operation of the operation unit 6. The locking portion 51a of the lock member 51 is in contact with the tapered surface 61a of the restricting portion 61 so as to be separated.

  The operation of the cup holder of this embodiment will be described. First, the case where the tray 2 is held at the lowest position will be described. A dotted line in FIG. 2 shows a state where the tray 2 is held at the lowest position. In this case, as shown in FIG. 9, the restricting portion 61 is disposed on the upper side of the engaging portion 51 a of the lock member 51 and the engaging portion 51 a is engaged with the restricting portion 61. The tray 2 is locked at the lowest position in the accommodation space 10.

  As shown in FIG. 8, when the pressing portion 62a of the knob 62 is pushed into the operation hole 11c, the knob 62 slides radially outward. The support shaft 64 is moved downward relative to the play hole 62 d provided in the knob 62. As the support shaft 64 moves downward, the operating rod 65 is moved downward, and the restricting portion 61 is moved downward. As shown in FIG. 9, the tapered surface 61 a of the restricting portion 61 pushes the locking portion 51 a of the lock member 51 toward the distal end side of the restricting portion 61. The lock member 51 rotates against the urging force of the lock urging member 56 toward the front end side of the restricting portion 61 (rearward direction in FIG. 9). The locking portion 51a of the lock member 51 is separated from the tapered surface 61a of the restricting portion 61 and is movable upward in the groove portion 12b. The locking part 51a moves upward in the second groove part 12b. That is, the pinion gear 35 a is rotated by the urging member 33 and moves upward along the rack gear 31. As shown in FIG. 2, the tray 2 is moved upward in the accommodation space 10.

  Here, as shown in FIG. 2, the pinion gear 35 a is connected to a transmission shaft provided with a speed buffer 37. A rapid change in the rotation of the pinion gear 35 a is suppressed by the speed buffer 37. For this reason, the pinion gear 35a rises while rotating at a low speed along the rack gear 31. The tray 2 moves up the storage space 10 at a low speed.

  As shown in FIG. 10, when the tray 2 is stopped at the uppermost position, the engaging portion 51a of the lock member 51 is engaged with the engagement hole formed in the side wall 13 of the second groove portion 12b by the urging force of the lock urging member 56. Inserted in 12h, the vertical movement of the lock member 51 is stopped. The engagement hole 12h corresponds to the upper engagement portion of the present invention. Thereby, the raising of the tray 2 is stopped, and the tray 2 remains at the uppermost position. At this time, as shown by the solid lines in FIGS. 1 and 2, the tray 2 is positioned at the same height as the upper wall 18 of the holder body 1. For this reason, the tray 2 is visually recognized integrally with the upper wall 18 of the holder main body 1, and the appearance is good.

  In the present embodiment, when the tray 2 is located at the uppermost position, the upper surface of the tray 2 is located at the same height as the upper wall 18 of the holder body 1, but the engagement provided in the second groove 12b By changing the height of the hole 12h up and down, the uppermost position of the tray 2 can be freely adjusted.

  The second groove portion 12b regulates the uppermost position of the tray 2 by engaging the engaging portion 51a of the lock member 51 in the engagement hole 12h, but the tray 12 is connected to the upper end 12f of the second groove portion 12b. The raising of the tray 2 can also be regulated by bringing the protrusions 23 protruding from the peripheral edge of the two into contact.

  As shown in FIGS. 2 and 6, the tray 2 located at the uppermost position is pushed downward. Then, the pinion gear 35 a moves downward along the rack gear 31 against the urging force of the urging member 33, and the tray 2 is moved below the accommodation space 10.

  As shown in FIG. 10, the locking portion 51a of the lock member 51 hits the upper end portion 61b of the restricting portion 61 protruding from the insertion hole 12c to the second groove portion 12b. A lower surface 51f of the locking portion 51a of the lock member 51 has a smooth taper shape. The urging force of the lock urging member 56 is smaller than the urging force of the return spring 67. For this reason, the locking portion 51 a of the lock member 51 gradually slides on the upper end portion 61 b of the restricting portion 61 and swings toward the distal end side of the restricting portion 61 as it descends. When the tray 2 is further moved downward, the locking portion 51 a of the lock member 51 is disengaged from the upper end portion 61 b of the restricting portion 61 and moves downward along the end surface of the leading end of the restricting portion 61. Located on the lower side. At this time, the lock member 51 abuts on the tapered surface 61 a of the restricting portion 61 while swinging toward the restricting portion 61 by the biasing force of the lock biasing member 56. Thereby, as shown by the dotted line in FIG. 10, the lock member 51 is locked to the restricting portion 61, and the tray 2 is held in the lower portion of the accommodation space 10.

  Although the restricting portion 61 is provided in the operation rod 65, the insertion hole 12c formed in the second groove portion 12b may be the restricting portion. When the insertion hole 12c is a restricting portion, the locking portion 51a of the lock member 51 is locked in the insertion hole 12c. When the operation part 6 is operated, the locking part 51a is pushed out from the insertion hole 12c by the operating rod 65, and the locking of the locking part 51a to the insertion hole 12c is released.

According to this embodiment, as shown in FIG. 2, the pinion gear 35a is rotatably supported on the tray 2. The pinion gear 35 a meshes with a rack gear 31 provided on the peripheral wall 11 of the holder body 1. The pinion gear 35 a moves upward while rotating on the rack gear 31 by the urging force of the urging member 33. The tray 2 supporting the pinion gear 35a is also moved upward.
When the tray 2 is pushed downward, the pinion gear 35 a is moved downward together with the tray 2 while rotating on the rack gear 31 against the urging force of the urging member 33.

  Here, the urging member 33 is provided on the tray 2. That is, the urging member 33 does not connect the holder body 1 and the tray 2 to suspend the tray 2 from the holder body 1. For this reason, in this embodiment, the urging member 33 does not restrict the rising position of the tray 2. Compared to the tray 2 of the cup holder 19 disclosed in Patent Document 1, the tray 2 of the present invention has a higher degree of freedom in the raising / lowering position and a higher degree of freedom in setting the uppermost position of the tray 2.

  The balance of the urging force of the return spring 67 and the lock urging member 56 is such that the rocking force of the lock member 51 generated by the lock urging member 56 is smaller than the return force to the upper side of the restricting portion 61 generated by the return spring 67.

(Fourth embodiment)
In the cup holder 19 of the present embodiment, as shown in FIGS. 25 and 26, the rack member 15 is arranged in the groove portion 12 in that the rack member 15 is arranged in the groove portion 12 while being biased upward. This is different from the first embodiment to be fitted.

As shown in FIG. 26, the rack member 15 has a guide hole 40 in the back wall 17. The guide holes 40 are provided at two locations on the back wall 17 in a shape extending in the vertical direction. The protrusion 41 of the back wall 14 of the groove 12 is inserted into the guide hole 40. The protrusion 41 protrudes radially inward from the back wall 14. When the protrusion 41 is inserted into the guide hole 40, the distal end surface is located radially outward from the inner peripheral surface of the back wall 17 of the rack member 15.
The rack member 15 is disposed in the groove 12 so as to be movable in the vertical direction in the groove 12 (or in a slidable state).

  As shown in FIGS. 25 and 26, a spring 42 is disposed below the rack member 15. The spring 42 is compressed and has an upper end fixed to the rack member 15 and a lower end fixed to the holder body 1. The upper end of the spring 42 is fixed to the lower end of the rack member 15. The lower end of the spring 42 is fixed to the bottom plate 8 of the holder body 1.

The spring 42 generates a biasing force that biases the rack member 15 upward. The biasing force of the spring 42 is smaller than the biasing force generated by the coil spring of the biasing member 33. The biasing force of the spring 42 is preferably 90% or less of the biasing force of the biasing member 33, and more preferably 75% or less.
The spring 42 biases the rack member 15 upward. That is, the spring 42 presses and holds the rack member 15 that is movable in the vertical direction within the groove portion 12.

  The operation of the cup holder 19 of this embodiment will be described. Operations that are not particularly mentioned are the same as those in the first embodiment.

  As shown in FIG. 26, the cup holder 19 of the present embodiment is stopped at the uppermost position when the tray 2 is pushed up by the coil spring of the urging member 33. At this time, the rack member 15 is pressed against the upper wall 18 by the spring 42. The rack member 15 and the gear member 35 have the same phase at both ends of the transmission shaft 34. In this case, as shown in FIG. 27, the transmission shaft 34 extends along the horizontal direction. Then, the tray 2 spreads along the horizontal direction at the same height as the upper wall 18 of the holder body 1 and has a good appearance.

  On the other hand, as shown in FIG. 28, when the rack member 15 and the gear member 35 are out of phase at both ends of the transmission shaft 34, the transmission shaft 34 is inclined. At this time, the tray 2 is also inclined, and the height of the upper wall 18 is shifted and the appearance is lowered.

  As shown in FIG. 28, the phase of the pinion gear 35 a of the gear member 35 is shifted at both ends of the transmission shaft 34. Specifically, in the transmission shaft 34, the right end 34R (right gear member 35R) in FIG. 28 is positioned below the left end 34L (left gear member 35L). In FIG. 28, the position of the right gear member 35R 'when there is no phase difference is indicated by a broken line.

The right rack member 15R and the left rack member 15L are pressed against the upper wall 18 by a spring 42 with a weak biasing force. In the state shown in FIG. 28, the transmission shaft 34 is acted on by a biasing force in the direction of pushing up the tray 2 by the coil spring of the biasing member 33. The tray 2 pushed up to the uppermost position is further restricted from moving upward by the holder body 1. At this time, the transmission shaft 34 continues to generate a biasing force in the direction of pushing up the tray 2.
The tray 2 restricts upward movement of the left end portion 34L (and the left gear member 35L) of the transmission shaft 34. The left end 34L (and the left gear member 35L) of the transmission shaft 34 is restricted from further rotation for upward movement.

On the other hand, a rotational force is also acting on the right end 34 </ b> R of the transmission shaft 34. The right end portion 34 </ b> R of the transmission shaft 34 is not subjected to a force that restricts rotation because the transmission shaft 34 is inclined. Specifically, the tray 2 is not in contact with the upper wall 18 of the holder body 1. In this case, the tray 2 can move until it comes into contact with the upper wall 18 of the holder body 1. In this state, the right end 34R (right gear member 35R) of the transmission shaft 34 is allowed to rotate further until the tray 2 contacts the upper wall 18 of the holder body 1.
As a result, the right end 34R (and the right gear member 35R) of the transmission shaft 34 is further rotated to push the tray 2 upward.

Then, the right end 34R of the transmission shaft 34 is rotated to push up the tray 2. When the right end 34R (and the right gear member 35R) rotates, the left end 34L (and the left gear member 15L) also rotates via the transmission shaft 34. Even if the left end 34L (and the left gear member 15L) tries to rotate, since the tray 2 is at the uppermost position, no further displacement of the tray 2 occurs.
At this time, the left end 34L (and the left gear member 15L) generates a force in a direction to lower the left rack member 15L downward by the rotation of the transmission shaft 34. The urging force of the spring 42 is applied to the left rack member 15L and is pressed against the upper wall 18. Since the urging force of the spring 42 is smaller than the urging force generated by the coil spring of the urging member 33, the left gear member 35L is pushed downward when the force generated by the rotation of the transmission shaft 34 becomes larger than the urging force of the spring 42. To change. As a result, as shown in FIG. 29, the left gear member 35L is pushed downward. The left end 34L is at a position corresponding to the uppermost position of the tray 2.

  As described above, the cup holder 19 of the present embodiment is configured so that the tray 2 can be connected to the upper wall 18 of the holder body 1 even when the phases of the rack member 15 and the gear member 35 located on both sides of the transmission shaft 34 are shifted. It can be arranged at the same height and looks good. In particular, this effect can be exhibited when the phase shift between the rack member 15 and the gear member 35 is shorter than the tooth pitch of the pinion gear 35a or the rack gear 31.

In the cup holder 19 of this embodiment, the protrusion 41 and the guide hole 40 may be provided in opposite members, respectively. That is, the protrusion 41 may be provided in the rack member 15, and the guide hole 40 may be provided in the groove 12.
The number of the protrusions 41 and the guide holes 40 is not limited. It can be set to a number that can be guided along the moving direction of the rack member 15 that changes in the vertical direction.
In the guide hole 40, one protrusion 41 may be inserted, or two or more protrusions 41 may be inserted.

  The spring 42 is not limited as long as it can generate a biasing force that biases the rack member 15 upward. The upper end of the spring 42 may be fixed at a place other than the lower end of the rack member 15.

  The spring 42 may be a tension spring whose upper end is fixed to the upper wall 18 of the holder body 1 and whose lower end is fixed to the rack member 15.

  Furthermore, the spring 42 may be a member or a device other than the coil spring shown in FIG. Any member or device that can generate a biasing force that biases the rack member 15 upward may be used.

  In other words, the cup holder 19 of the present embodiment has a projection 41 in one of the rack member 15 and the groove 12 and a guide hole 40 into which the projection 41 is inserted in the other, and biases the rack member 15 upward.

A rack gear 31 is provided in the groove portion 12, and the pinion gear 35 a provided on the tray 2 moves on the rack gear 31. Here, when the pinion gear 35a is positioned at a height where the movable wall 71 exists, the side surface of the movable wall 71 cannot contact the pinion gear 35a to close the groove 12. When the pinion gear 35a is positioned below the movable wall 71, the movable wall 71 is not obstructed by the pinion gear 35a, and the movable wall 71 is urged by the wall urging member 75 to close the groove portion 12. By closing the groove 12, the movable wall 71 can form a wall surface that is flush with the fixed wall 11a. For this reason, the groove part 12 is not visible at all, and the appearance of the accommodation space 10 is improved.

  When the tray 2 is to be raised, the movable wall 71 is pushed to open the groove 12. As a result, the movable wall 71 moves backward from the groove 12, and the pinion gear 35a moves upward on the rack gear 31 to raise the tray 2.

(7) In the above (6), the tray 2 protrudes toward the groove portion 12 and comes into contact with the lower end of the movable wall 71 when the tray 2 is located at the lowest position (the outer peripheral surface of the gear member 35). Preferably it has an upper side 35p).
When the tray 2 is to be raised, the movable wall 71 is pushed in the direction in which the groove 12 opens. As a result, the movable wall 71 is retracted from the groove 12, the contact portion is detached from the movable wall 71, and the tray 2 can be raised.

  (8) In the above (6) or (7), the peripheral wall 11 has a pair of groove portions 12 at portions facing each other with the accommodation space 10 in between, and the peripheral wall 11 is divided into two sections by the pair of groove portions 12. It is preferable that the peripheral wall 11 of one division is comprised by the movable wall 71, and the peripheral wall 11 of the other division is comprised by the fixed wall 11a.

  A boundary portion between the movable wall 71 and the fixed wall 11 a becomes the groove portion 12. For this reason, when looking in the accommodation space 10, the movable wall 71 and the fixed wall 11a cannot be distinguished, and the boundary portion between the movable wall 71 and the fixed wall 11a is difficult to see. For this reason, the peripheral wall appears to be surrounded by one continuous wall, and looks good.
