## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cup holder in which a tray that holds a bottom part of a beverage container can be moved vertically.
2. Description of the Related Art
A cup holder is loaded in a vehicle interior of a vehicle. The cup holder accommodates a beverage container of various heights. The cup holder is designed to cause the bottom part of the beverage container to be vertically moved according to the height of the beverage container.
For example, in Japanese Unexamined Patent Publication No. 2010-215073, it is disclosed that, by providing a spring on the bottom plate, the bottom plate is vertically moved according to the load of the cup. In Japanese Unexamined Patent Publication No. 2007-196884, it is disclosed that, by inserting a screw shaft into a screw hole in the bottom plate, the screw shaft is rotated according to a moving amount of an operation member, and the bottom plate is vertically moved. In Japanese Unexamined Patent Publication No. 2003-48472, it is disclosed that a sidewall part has many latch claws whose recessed portions or protruded portions have substantially sawtooth shapes in a vertical cross section, and a latch piece that is formed on a bottom receiving part is detachably latched with a latch claw at an arbitrary height. In Japanese Unexamined Patent Publication No. 2002-362212, it is disclosed that a lock claw that is formed on the tray is detachable with any of two lock grooves that have different heights on the holder body.
SUMMARY OF THE INVENTION
As described above, there have been various mechanisms for adjusting the height of the tray of the cup holder. The inventor has developed a cup holder that can adjust the height of the tray by a new configuration.
The present invention has been made in view of the above situation, and an object of the invention is to provide a cup holder that can adjust the height of the tray.
(1) A cup holder according to the present invention includes a cylindrical holder body that has an accommodation space surrounded by a sidewall, a tray that is accommodated in the accommodation space and is held to be vertically movable between a first position and a second position whose perpendicular direction is different from that of the first position, and a height adjuster that causes the tray to be vertically moved and held at the first position or the second position. The height adjuster includes a lock member that is turnably held by the tray, a guide groove that is formed on a sidewall of the holder body and that enables the lock member to move in a perpendicular direction, a first latch recessed portion that is formed on a groove side surface which faces the guide groove on the sidewall of the holder body and that causes the tray to be held at the first position by latching the lock member, a second latch recessed portion which is formed at a portion of the groove side surface of the holder body and whose position in a perpendicular direction is different from that of the first latch recessed portion and which causes the tray to be held at the second position by latching the lock member, a latch energizing member that energizes the lock member to a latch direction for latching the lock member with the first latch recessed portion or the second latch recessed portion, an operation member that cancels latch of the lock member with the first latch recessed portion by causing the lock member to turn to a cancellation direction opposite to the latch direction when the tray is located at the first position, and a movement energizing member that energizes the tray from the first position toward the second position so as to vertically move the lock member of which latch with the first latch recessed portion has been canceled toward the second latch recessed portion through the guide groove.
The cup holder of the above configuration has the tray that is provided in the accommodation space of the holder body, and the height adjuster that adjusts the height of the tray. The lock member of the height adjuster is turnably provided on the tray, and the lock member also moves vertically following a vertical movement of the tray. The lock member is energized, by the latch energizing member, to the latch direction to be latched with the first latch recessed portion or the second latch recessed portion. While the lock member is being latched with the first latch recessed portion, the tray is being held at the first position. While the lock member is being latched with the second latch recessed portion, the tray is being held at the second position.
When the latch of the lock member with the first latch recessed portion is canceled by the operation member while the tray is being held at the first position, the tray is moved from the first position to the second position by the movement energizing member. Following this movement, the lock member that is provided on the tray moves toward the second latch recessed portion while being guided by the guide groove, and is latched with the second latch recessed portion. The tray is held at the second position.
When the latch of the lock member with the second latch recessed portion is canceled and also when load is applied to the direction from the second position to the first position while the tray is being held at the second position, the tray is moved from the second position to the first position. Following this movement, the lock member that is provided on the tray moves downward by being guided by the guide groove, and is latched with the first latch recessed portion. The tray is held at the first position.
As described above, according to the present invention, when the lock member is turned to the cancellation direction of canceling the latch with the first latch recessed portion by operating the operation member, the tray becomes able to be moved vertically, and the tray can be moved from the first position to the second position.
The height of the tray can be adjusted by a simple configuration.
(2) Preferably, the operation member has a tapered portion that causes the lock member to turn to the cancellation direction when the operation member is operated. By operating the operation member, the tapered portion of the operation member causes the lock member to turn to the cancellation direction, and the latch of the lock member can be smoothly canceled.
(3) Preferably, the lock member has a protruded portion that is extended to an outer side in the radial direction, and the protruded portion holds the tray at the first position or the second position by being latched with the first latch recessed portion or the second latch recessed portion.
The protruded portion of the lock member is securely latched with the first latch recessed portion or the second latch recessed portion. The tray can be securely held at the first position or the second position.
(4) Preferably, the lock member has a plurality of the protruded portions laid out in the circumferential direction, and on the sidewall of the holder body, the guide groove, the first latch recessed portion, and the second latch recessed portion are respectively formed at positions opposite to the protruded portions.
When the plurality of protruded portions is laid out in the circumferential direction of the lock member, and when each protruded portion is latched with the first latch recessed portion or the second latch recessed portion, the tray can be stably held in the first latch recessed portion or second latch recessed portion in the holder body.
(5) Preferably, the lock member has an inclined portion that is brought into contact with the opening peripheral edge of the second latch recessed portion. With the inclined portion formed on the lock member, and by latching the inclined portion with the opening peripheral edge of the second latch recessed portion, when pressing load is applied to the tray, the latch of the lock member with the second latch recessed portion is canceled by detaching the lock member from the second latch recessed portion by using component force of the pressing load along the inclined portion. When the tray is further pressed in this state, the tray can be moved from the second position to the first position. Due to the simple configuration, the latch of the lock member with the second latch recessed portion can be canceled.
According to the cup holder of the present invention, when the latch of the lock member with the first latch recessed portion is canceled by operating the operation member, the lock member is vertically moved toward the second latch recessed portion along the guide groove. Therefore, the height of the tray can be adjusted.

A compression spring 9 is provided between the lower part of the working part 83 and a seat portion lit that is formed on the body part 11. When the operation member 8 is pressed downward, the compression spring 9 alleviates the movement of the operation member 8 to a lower direction.
Operation of the cup holder according to the present embodiment will be described. The cup holder 10 that is shown in FIG. 1 shows a state that the tray 2 is being held at the lower position (the first position). When the tray 2 is located at the lower position, the protruded portion 72 of the lock member 7 is being latched with the lower latch recessed portion 11m of the holder body 1 by the energizing force of the latch energizing member 6 in the clockwise direction (the latch direction) in FIG. 4, and the tray 2 is being held at the lower position.
As shown FIG. 1, when the operating part 81 of the operation member 8 is pressed downward, the working part 83 of the operation member 8 is moved to the lower direction. Based on the movement of the working part 83 to the lower direction, the tapered portion 84 is brought into contact with the protruded portion 72 of the lock member 7, so that the protruded portion 72 is turned to the counterclockwise direction (the cancellation direction) in FIG. 4 and the latch state of the lower latch recessed portion 11m of the holder body 1 is canceled. The tray 2 is always energized to the upper direction by the movement energizing member 5. Based on the detachment from the lower latch recessed portion 11m of the protruded portion 72, the lock member 7 having the protruded portion 72 is moved together with the tray 2 to the upper side along the guide groove 11j, by the upward energizing force of the movement energizing member 5 that is applied to the tray 2.
As shown in FIG. 7, when the protruded portion 72 of the lock member 7 is located at the upper latch recessed portion 11n, the protruded portion 72 of the lock member 7 is latched with the upper latch recessed portion 11n by the energizing force of the latch energizing member 6 in the clockwise direction (the latch direction) in FIG. 4, the energizing force always being applied to the lock member 7. The tray 2 is held at the upper position (the second position).
As shown in FIG. 8, an inclined portion 72a is formed on the lower surface of the protruded portion 72 (A in FIG. 8) of the lock member 7. While the protruded portion 72 is being latched with the upper latch recessed portion 11n, the inclined portion 72a of the protruded portion 72 is kept in contact with the lower edge of the opening of the upper latch recessed portion 11n. 
To return the tray 2 to the lower position again, the bottom part 21 of the tray 2 is pressed downward. Downward pressing load is applied to the lock member 7 that is being held on the tray 2. When the downward pressing load has exceeded the upward energizing force of the movement energizing member 5 and further the component force in the direction along the inclined portion 72a of the downward pressing load has exceeded the component force in the direction along the inclined portion 72a of the latch energizing member 6, the protruded portion 72 of the lock member 7 is moved to the right direction (the cancellation direction) in FIG. 8 along the inclined portion 72a and is detached from the upper latch recessed portion 11n. The pressing load at the time of starting the protruded portion 72 to be moved to the cancellation direction is preferably larger than the mass of the beverage container. After the protruded portion 72 is detached from the upper latch recessed portion 11n, the protruded portion 72 is moved to the lower direction along the guide groove 11j, as shown by B in FIG. 8.
When the protruded portion 72 is moved downward to the position of the lower latch recessed portion 11m in the guide groove 11j, the lock member 7 is turned to the clockwise direction (the latch direction) in FIG. 4 by the energizing force of the latch energizing member 6, and the protruded portion 72 is latched with the lower latch recessed portion 11m as shown by C in FIG. 8. As a result, the tray 2 is held at the lower position.
As described above, when the lock member 7 is turned to the cancellation direction of canceling the latch of the protruded portion 72 with the lower latch recessed portion 11m or the upper latch recessed portion 11n by the operation of the operation member 8, the tray 2 is vertically movable and can be moved to the lower position or the upper position. The height of the tray 2 can be adjusted by a simple configuration.
The operation member 8 has the tapered portion 84 that causes the lock member 7 to be moved to the cancellation direction when the operation member 8 is operated. By the operation of the operation member 8, the tapered portion 84 of the operation member 8 causes the lock member 7 to be moved to the cancellation direction, and the latch of the lock member 7 can be canceled smoothly.
The lock member 7 has the protruded portion 72 that is extended to the outer side in the radial direction. The lock member 7 holds the tray 2 at the lower position or the upper position by having the protruded portion 72 latched with the lower latch recessed portion 11m or the upper latch recessed portion 11n. The protruded portion 72 of the lock member 7 is securely latched with the lower latch recessed portion 11m or the upper latch recessed portion 11n. The tray 2 can be securely held at the lower position or the upper position.
The lock member 7 has a plurality of protruded portions 72 laid out in the circumferential direction. On the sidewall 11d of the holder body 1, there are respectively formed the guide groove 11j, the lower latch recessed portion 11m, and the upper latch recessed portion 11n at positions opposite to the protruded portion 72. The plurality of protruded portions 72 is laid out in the circumferential direction of the lock member 7. The tray 2 can be stably held on the holder body 1, by having each protruded portion 72 latched with the lower latch recessed portion 11m or the upper latch recessed portion 11n. 
The damper device 15 that alleviates the moving speed of the tray 2 is provided on the holder body 1. When the latch of the lock member 7 with the lower latch recessed portion 11m is canceled, the tray 2 is raised by the movement energizing member 5. The rising speed of the tray 2 at this time is alleviated by the damper device 15, and a fall of the beverage container that is mounted on the tray 2 or a spill of the beverage can be prevented.
The operating part 81 of the operation member 8 is laid out to be able to advance and retreat in the hole part 14b that is formed on the flange portion 14 of the holder body 1. The operating part 81 can be easily operated.

Configurations of the second embodiment are similar to those of the first embodiment, except the configuration of the operation member 8.
As shown in FIG. 11, when the tray 2 is located at the lower position, the protruded portion 72 of the lock member 7 is being latched with the lower latch recessed portion 11m of the holder body 1. The rod member 87 of the operation member 8 is energized to the upper side by the compression spring 9. The supporting axis 88 that is inserted in the supporting hole 87a of the rod member 87 is located at the upper ends of the long holes 86d of the operation case 86, and is also located at the upper ends of the play holes 85c of the sliding part 85b of the operation knob 85.
When the operating part 85a of the operation knob 85 is pressed to the outer side in the radial direction, the operation knob 85 is moved to the outer side in the radial direction, as shown by a two-dot chain line in FIG. 11. The upper ends of the play holes 85c that are formed on the sliding part 85b of the operation knob 85 are located at the outer side in the radial direction, and are inclined to a lower direction toward the inner side in the radial direction. When the operation knob 85 is moved to the outer side in the radial direction, the supporting axis 88 located at the upper ends of the play holes 85c slides toward the lower direction which is the inner side in the radial direction of the play holes. Accordingly, the supporting axis 88 shifts in the long holes 86d of the operation case 86 from the upper ends toward the lower ends. The rod member 87 is moved to a lower direction.
Based on the downward movement of the working part 83, the tapered portion 84 is brought into contact with the protruded portion 72 of the lock member 7, and the latch state of the protruded portion 72 with the lower latch recessed portion 11m of the holder body 1 is canceled. The tray 2 is always energized to the upper direction by the movement energizing member 5. When the protruded portion 72 is detached from the lower latch recessed portion 11m, as shown in FIG. 12, the lock member 7 having the protruded portion 72 is moved to the upper side along the guide groove 11j, together with the tray 2, by the upward energizing force of the movement energizing member 5 that is applied to the tray 2.
The operating part 81 of the operation member 8 is laid out to be able to advance and retreat in the hole part 11u that is formed at the upper side of the sidewall 11d of the body part 11 of the holder body 1. When the beverage container is in the state of being accommodated in the accommodation space 11c, the operating part 81 is hidden by the beverage container, and it becomes difficult to operate the operating part 81. Therefore, when the beverage container is accommodated, erroneous operation of the operating part 81 does not occur and hence malfunction of the tray 2 can be prevented.
In the first and second embodiments, a tensile coil spring is used as the movement energizing member 5 that energizes the tray 2 from the lower position toward the upper position. However, other tension springs may be also used. Alternatively, a compression spring such as a compression coil spring may be used. When using the compression coil spring, it may be arranged such that the upper end of the compression coil spring is held at the seat portion that is formed at the lower end part of the pillar wall 23 of the tray 2 and that the lower end of the compression coil spring is latched with the seat portion which is protruded from the lower part of the sidewall 11d of the holder body 1.
In the first and second embodiments, in order to cancel the latch of the lock member 7 with the upper latch recessed portion 11n, the inclined portion 72a that is formed on the protruded portion 72 of the lock member 7 is latched with the opening peripheral edge of the upper latch recessed portion 11n (see FIG. 8). However, instead of this arrangement, there may be provided an operation member that cancels the latch of the lock member 7 with the upper latch recessed portion 11n by causing the lock member 7 to turn to the cancellation direction opposite to the latch direction when the tray 2 is located at the upper position. The configuration of this operation member can be similar to the configuration of the operation member 8 that cancels the latch with the lower latch recessed portion 11m of the lock member 7.
In the first and second embodiments, when the tray 2 is located at the lower position, the latch of the lock member 7 with the lower latch recessed portion 11m (the first latch recessed portion) is canceled by the operation of the operation member 8 so that the tray 2 is moved to the upper position by the upward energizing force of the movement energizing member 5. Alternatively, when the tray 2 is located at the upper position, the latch of the lock member 7 with the upper latch recessed portion 11n (the second latch recessed portion) may be canceled by the operation of the operation member 8 so that the tray 2 is moved to the lower direction by the downward energizing force of the movement energizing member 5.
Further, the lock member 7 is held by being interposed between the tray 2 and the holding member 78. However, the lock member 7 may be turnably held on the bottom part 21 of the tray 2 without using the holding member 78.
Although the latch energizing member 6 that energizes the lock member 7 to the latch direction is a torsion spring, a thin plate spring may be also used.
In the first and second embodiments, the damper device 15 is fixed to the holder body 1, and the rack 24 is formed on the pillar wall 23 of the tray 2. Alternatively, the damper device 15 may be fixed to the pillar wall 23, and the rack 24 may be formed at the outer surface side of the sidewall 11d of the holder body 1. Further, the damper device 15 may not be present. Although the pillar wall 23 is provided on the tray 2 and the guide groove 11j is covered from the outer side to prevent a small object from falling from the guide groove 11j to the outer side of the holder body 1, the pillar wall 23 may not be present.
The accommodation space 11c of the holder body 1 has one cylindrical part 11x, and a small space 11y for accommodating the knob adjacently to the cylindrical part 11x (FIG. 1). The accommodation space 11c is not limited to this configuration and may have a shape formed by only one cylindrical part 11x, or may have a shape formed by having two cylindrical parts 11x adjacently.
On the sidewall 11d of the body part 11 of the holder body 1, there may be provided in projection a supporting member to be able to advance and retreat to prevent the fall of the beverage container.
The cup holder according to the present embodiment is used as an indoor part of a vehicle. The cup holder according to the present embodiment can be also installed on a chair, furniture, and the like, without being limited to the interior part of a vehicle.
