  Moreover, in the hanging door shelf described in Patent Document 2, when the elevating shelf is moved upward by the constant load spring, the elevating shelf is suddenly stopped at the rising end position, and an impact may occur.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a hanging cabinet that can alleviate the impact when the elevating shelf is moved to the rising end position and the lowering end position.

  In order to achieve the above object, a hanging cupboard according to the present invention is a hanging cupboard having a liftable shelf, and supports a cupboard body, and supports a shelf between a rising end position and a lowering end position with respect to the cupboard body. Operated by a relative movement between the movable frame and the driven rod, a movable frame attached to the cupboard body so as to be movable in the vertical direction, a driven rod attached to the movable frame so as to be movable in the vertical direction relative to the movable frame And a damper mechanism disposed between the movable frame and the driven rod, and the cupboard body is an upper side with which the driven rod abuts so as to define an upper limit position and a lower limit position of the driven rod with respect to each other. It has a limit part and a lower limit part, and the driven rod can move downward with respect to the driven rod when the movable frame is in the lift end position. The lower limit part is arranged so that the driven rod comes into contact with the movable frame while moving from the rising end position to the lowering end position, so that the driven rod comes into contact with the lower limit part, The movable frame moves downward with respect to the driven rod, and the downward movement of the movable frame with respect to the cupboard body is suppressed by the damper mechanism, and the movable rod is driven when the movable frame is at the lowering end position. The upper limit part is arranged so that the driven rod comes into contact with the movable frame while moving from the lowering end position to the rising end position. After coming into contact with the upper limit part, the movable frame moves upward with respect to the driven rod, and the upward movement of the movable frame relative to the cupboard body Dynamic is characterized in that it is suppressed by the damper mechanism.

  In the hanging cabinet configured as described above, when the shelf is lowered, the movable frame can be freely lowered with respect to the cabinet main body at a relatively high speed until the driven rod comes into contact with the lower limit portion. After the driven rod comes into contact with the lower limit portion, the driven rod cannot be lowered by the lower limit portion, so that the movable frame is lowered relative to the driven rod, and the damper mechanism operates. As a result, the descending speed of the movable frame with respect to the cupboard body is reduced, and the impact at the descending end position can be mitigated.

  Further, when the shelf is raised, the movable frame can be freely raised with respect to the cupboard body at a relatively high speed until the driven rod comes into contact with the upper limit portion. After the driven rod comes into contact with the upper limit portion, the driven rod cannot be raised by the upper limit portion, so the movable frame rises relative to the driven rod, and the damper mechanism operates. As a result, the rising speed of the movable frame relative to the cupboard body is reduced, and the impact at the rising end position can be mitigated.

  In the embodiment of the above-mentioned hanging cabinet, preferably, the driven rod has a head that abuts the upper limit portion and the lower limit portion at the upper end portion thereof.

  In the embodiment of the hanging cupboard, preferably, the driven rod has a rack, the movable frame has a pinion that engages with the rack, and the pinion is attached to the movable frame via a rotary damper. .

In the embodiment of the above-described hanging cabinet, preferably, the movable frame is biased upward .

The weight of the balance weight 23 is preferably substantially the same as the weight of the movable frame 3 and the shelf plate body 4, and more preferably, the movable frame 3 and the shelf plate body 4 can be lowered by their own weight. 3 and a slightly lighter weight than the shelf 4.

  FIG. 6 is a partial perspective view of the shelf board. As shown in FIG. 6, the shelf board body 4 has arms 40 provided on the left and right sides, and two plate bodies 41 attached to the left and right arms 40 so as to bridge the left and right arms 40. The base portion 40a of the arm 40 is rotatably attached to the lower end portion of the vertical frame structure 30a via a shaft body 42. Thereby, when the movable frame 3 is in the descending end position 3b, the shelf plate body 4 has a horizontal position 4a (see FIG. 1 (d) and FIG. 5) extending from the base portion 40a in the horizontal direction, and a vertical direction. It can be rotated between a standing position 4b (see FIG. 1A and FIG. 4) extending upward from the base 40a along the frame structure 30a. The shaft body 42 is preferably a rotary damper having a rotor portion and a stator portion. One of the rotor portion and the stator portion is fixed to the vertical frame structure 30 a of the movable frame 3, and the other is the shelf plate body 4. It is fixed to the arm 40. The center of gravity of the shelf plate body 4 is preferably located in front of the shaft body 42 so that the shelf plate body 4 rotates from the standing position 4b to the horizontal position 4b by its own weight.

  It is preferable that the left-right frame structure 30b on the lower side of the movable frame 3 functions as a stopper for the shelf board 4 at the horizontal position 4a. Further, the shelf plate body 4 can be held at the standing position 4b by a holding portion 6 described later.

  Further, the movable frame 3 prevents the movable frame 3 from rising when it is at the lowering end position 3b but the shelf plate body 4 is not moved to the standing position (see FIG. 2A). It has a lock body 80 for this purpose. 7 and 8 are side views of the shelf board and the lock body. 9 and 10 are cross-sectional views of the lock body.

  As shown in FIGS. 7 to 10, the lock body 80 has a vertically elongated shape having an upper end portion 81 and a lower end portion 82, and rotates to the vertical frame structure 30 a above the shelf plate body 4. It is attached in a possible manner and is arranged in a casing 34 that is elongated vertically. The front surface of the casing 34 constitutes a restricting portion 34a with which the shelf plate body 4 abuts in order to restrict the shelf plate body 4 from pivoting to the opposite side beyond the standing position 4b. The lock body 80 has a blocking position 80a (see FIGS. 7 and 9) in which an upper end portion 81 protrudes from a hole provided in the rear surface of the casing 34 and a lower end portion 82 protrudes from a hole provided in the front surface of the casing 34. The upper end portion 81 and the lower end portion 82 can pivot between the retracted positions 80b (see FIGS. 8 and 10) in which they are retracted into the casing 34. The upper end portion 81 of the lock body 80 at the blocking position 80a can be engaged with a blocking piece 25a provided on the cupboard body 2 so as to prevent the movable frame 3 from rising when the movable frame 3 is lifted. The lock body 80 is biased to the blocking position 80 a by a spring 84.

  The movable frame 3 is held at the lift end position 3 a by the latch assembly 5. FIG. 11 is a perspective view showing the latch assembly partially cut away.

  The latch assembly 5 is embedded in the bottom plate 2a of the cupboard body (see FIGS. 4 and 5). The latch assembly 5 includes a latch portion 50 and an operation slide portion 51 that are connected to each other, and a main body 52 that slidably holds the latch portion 50 and the operation slide portion 51. The latch portion 50 is slidable between a protruding position 50a (see FIG. 4) protruding from the bottom plate 2a into the installation space 1c and a retracted position 50b (see FIG. 5) to be drawn into the bottom plate 2a. Is biased to the protruding position 50a. When the latch portion 50 is in the projecting position 50a, the latch portion 50 extends below the projecting portion 30d of the lower left and right frame structure 30b in the ascending end position 3a (see FIGS. 4 and 5), and the movable frame. 3 can be prevented from descending. The lower surface of the tip of the latch portion 50 is rounded or inclined so that the latch portion 50 is pushed into the retracted position 50b by the movable frame 3 that has been lifted from the lowering end position 3b. The operation slide portion 51 has an operation surface 51a with which the fingertip comes into contact so that it can be pulled forward.

  Next, the holding unit 6 will be described in detail. FIG. 12 is a perspective view of the holding part with a part broken away. FIG. 13 is a perspective view showing only the driven rod of the holding portion. FIG. 14 is a partial cross-sectional perspective view of the holding portion. FIG. 15 is an enlarged perspective view showing a part of the driven rod of the holding portion and the latch case separately. 16-19 is a figure which shows operation | movement of a holding | maintenance part. 20 and 21 are views showing the operation of the latch body of the holding portion when lowered and when raised, respectively.

  As shown in FIG. 12, the holding | maintenance part 6 is integrated in the up-down direction frame structure 30a. The vertical frame structure 30a has a cylindrical shape with a rectangular cross section, and the latch case 32 of the holding unit 6 is fixed to an intermediate portion in the vertical direction. The latch case 32 accommodates a latch body 60 for holding the shelf plate body 4 in the upright position 4b so as to be slidable in the left-right direction A. The latch body 60 has a latch pin 60 c extending toward the shelf plate body 4 at the standing position 4. The latch body 60 has a gap between a projecting position 60a where the latch pin 60c passes through a hole provided in the vertical frame structure 30a and projects therefrom, and a retracted position 60b where the latch pin 60c is retracted into the vertical structure 30a. It is slidable and is biased to the protruding position 60a by a spring 32a (see FIG. 14). When the latch body 60 is in the protruding position 60a, the latch pin 60c extends into the hole 40b (see FIG. 20A) of the shelf board 4 in the standing position 4, thereby raising the shelf board 4 upright. Can be held in position. The tip of the latch pin 60c is likely to enter the hole 40d when the shelf board 4 moves from the horizontal position 4a to the standing position 4b, but the latch pin 60c does not move when the shelf board 4 moves from the standing position 4b to the horizontal position 4a. It is preferable to have a shape that is difficult to be removed from the hole 40d, for example, a hemispherical shape.

  As shown in FIGS. 13 and 14, the follower rod 70 for sliding the latch body 60 in the left-right direction A can be moved in the up-down direction B along the guide provided in the latch case 32. It is attached to the body 30a (that is, the movable frame 3). The driven rod 70 is elongated in the vertical direction, the upper end portion thereof, that is, the head 71 is positioned above the vertical frame structure 30a, and a rack 72 extending in the vertical direction is formed in the lower half portion. Yes. The rack 72 engages with a pinion 32b provided in the latch case 32, and a rotary damper 32c (not shown) is built in the pinion 32b. Thus, when the vertical frame structure 30a (movable frame 3) moves relative to the driven rod 70 in the vertical direction B, by rotating the pinion 32b engaged with the rack 72 and operating the rotary damper 32c, The vertical frame structure 30a is decelerated.

  The head 71 of the driven rod 70 extends in the horizontal direction and can contact the lower limit protrusion 21a provided on the guide portion 21 from above (see FIG. 18), and the upper portion provided on the guide portion 21. The limit protrusion 21b can be contacted from below (see FIG. 19). That is, the vertical movement range of the driven rod 70 with respect to the guide portion 21 (ie, the cupboard body 2) is regulated by the lower limit protrusion 21a and the upper limit protrusion 21b.

  As shown in FIG. 14, the driven rod 70 is disposed behind the latch body 60, and has an operation pin 73 extending toward the latch body 60 as shown in FIG. 15. The operating pin 73 is movable between a protruding position 73a protruding from the driven rod 70 and a retracted position 73b drawn into the driven rod 70, and is biased to the protruding position 73a by a spring (not shown). Yes. The operation pin 73 and the latch body 60 are provided when the vertical frame structure 30a (that is, the movable frame 3) is at the lift end position 3a and the head 71 of the driven rod 70 is in contact with the upper limit protrusion 21b. The latch body 60 is configured to be positioned below the operation pin 73. Further, the operating pin 73 and the latch body 60 are such that the vertical frame structure 30a (that is, the movable frame 3) is at the lowering end position 3b and the head 71 of the driven rod 70 is in contact with the lower limit protrusion 21a. The latch body 60 is configured to be positioned above the operation pin 73 when being in operation. Therefore, when the movable frame 3 descends, the latch body 60 moves from a position above the operation pin 73 to a position below it, and when the movable frame 3 rises, the latch body 60 moves from the operation pin 73. Move from the lower position to the upper position.

  The latch body 60 includes a lowering cam portion 61a that engages with the operation pin 73 when the vertical frame structure 30a (that is, the movable frame 3) is lowered, and the vertical frame structure 30a (that is, the movable frame 3). ) Has an upward cam portion 61d that engages with the operating pin 73 when the upper portion is lifted. The descending cam portion 61a is configured by a groove for receiving the operation pin 73 so that the latch body 60 moves from the protruding position 60a to the retracted position 60b. Specifically, the groove has a groove lower end 61b that is positioned and opened to receive the operating pin 73 when the latch body 60 is in the protruding position 60a, and an operating pin when the latch body 60 is in the retracted position 60b. The groove upper end 61c is positioned so as to release the groove, and the groove upper end 61c is curved between the groove lower end 61b and the groove upper end 61c. The ascending cam portion 61d is configured by a groove for receiving the operation pin 73 without moving the latch body 60 from the protruding position 60a. Specifically, the groove has a groove upper end 61e that is positioned and opened to receive the operating pin 73 when the latch body 60 is in the protruding position 60a, and the operating pin 73 is retracted from the protruding position 73a to the retracted position 73b. As it moves, it becomes shallower downward and disappears.

  The vertical position of the vertical frame structure 30a when the latch body 60 is retracted to the retracted position 60b, that is, the position of the lower limit protrusion 21a with which the driven rod 70 abuts is from the standing position 4b toward the horizontal position 4a. It is determined so that the moving shelf board 4 does not interfere with the cupboard body 2.

  Next, the operation and action of the hanging cupboard which is an embodiment of the present invention will be described.

  First, the case where the movable frame 3 and the shelf plate 4 housed in the shelf body 2 are moved to the descent end position 3b and the horizontal position 4a, respectively, will be described.

  In a state where the movable frame 3 is at the rising end position 3a and the shelf plate body 4 is held at the standing position 4b by the holding portion 6, the operation slide portion 51 is operated to move the latch portion 50 to the retracted position 50b. As a result, the movable frame 3 and the shelf board 4 move downward due to their own weight and are gradually accelerated.

  When the movable frame 3 is at the rising end position 3a and begins to descend from the rising position 3a (see FIG. 16), the latch body 60 is urged to the protruding position 60a. 4b. Accordingly, the shelf plate body 4 is prevented from rotating from the standing position 4b toward the horizontal position 4a.

  When the head 71 of the driven rod 70 contacts the lower limit protrusion 21a (see FIG. 17), the movement of the driven rod 70 relative to the cupboard body 2 is prevented. As a result, the vertical frame structure 30 a moves relative to the driven rod 70 downward. At this time, the rack 72 of the driven rod 70 rotates the pinion 32b, and the rotary damper 32c built in the pinion 32b operates. Therefore, after the head 71 of the driven rod 70 comes into contact with the lower limit protrusion 21a, the descending vertical frame component 30a, that is, the movable frame 3 and the shelf 4 is decelerated and the descent is completed. It descends to position 3b and stops (see FIG. 18).

  When the vertical frame structural body 30a moves downward relative to the driven rod 70, the groove lower end 61b of the lower cam member 61a of the latch body 60 receives the operating pin 73 of the driven rod 70 (FIG. a)). As the vertical frame structure 30a further descends, the operation pin 73 moves the latch body 60 to the retracted position 60b via the descending cam portion 61a (see FIG. 20B). When the vertical frame structure 30a is further lowered, the latch body 60 releases the operating pin 73 from the groove upper end 61c of the lowering cam portion 61a, and the latch body 60 is moved again to the protruding position 60a by the spring 32a. .

  When the latch body 60 is moved from the protruding position 60a to the retracted position 60b, the shelf board body 4 starts moving from the standing position 4b to the horizontal position 4a by its own weight. When the latch body 60 is moved again to the protruding position 60 a, the shelf plate body 4 is in a state of being released from the latch body 60. The shelf plate body 4 rotates to the horizontal position at a speed controlled by a rotary damper built in the shaft body 42.

  When the shelf plate body 4 rotates from the standing position 4b, the lock body 80 rotates from the retracted position 80b to the protruding position 80a (see FIG. 9). Thereby, the upper end part 81 of the lock body 80 and the blocking piece 25a of the cupboard body 2 are aligned in the vertical direction. Accordingly, it is possible to prevent the movable frame 3 from being raised without rotating the shelf plate body 4 to the standing position 4b.

  Next, the case where the movable frame 3 and the shelf board 4 are stored in the cupboard body 2 will be described.

  The shelf plate body 4 at the horizontal position 4a is rotated by hand to the standing position 4b. Since the tip of the latch pin 60 c is hemispherical, the shelf plate body 4 is held by the latch body 60 by pushing the shelf plate body 4. Thereby, the lower end portion 82 of the lock body 80 is pushed, the lock body moves from the protruding position 80a to the retracted position 80b, and the movable frame 3 can be raised.

  Next, when the movable frame 3 is lifted by hand, the driven rack 70 is also lifted from the lower limit protrusion 21a. The driven rack 70 tends to descend by its own weight toward the vertical frame structure 30a. However, the rack 72, the pinion 32b, and the rotary damper 32c built in the rack 72 become resistances, and are substantially separated from the vertical frame structure 30a. Lifted without relative movement.

  When the head 71 of the driven rod 70 comes into contact with the upper limit protrusion 21b (see FIG. 19), the movement of the driven rod 70 relative to the cupboard body 2 is prevented. As a result, the vertical frame structure 30a moves relative to the driven rod 70 upward. At this time, the rack 72 of the driven rod 70 rotates the pinion 32b, and the rotary damper 32c built in the pinion 32b operates. Therefore, after the head 71 of the driven rod 70 comes into contact with the upper limit protrusion 21a, the lifted vertical frame member 30a, that is, the movable frame 3 and the shelf 4 is decelerated and the lift end position 3a. (See FIG. 16). The movable frame 3 is held at the lift end position 3 a by the latch assembly 5.

  As the vertical frame structure 30a moves upward relative to the driven rod 70, the groove upper end 61e of the raising cam portion 61d of the latch body 60 receives the operation pin 73 of the driven rod 70 (FIG. a)). As the vertical frame structure 30a further rises, the groove of the ascending cam portion 61d becomes shallower, and the operating pin 73 is moved from the protruding position 73a to the retracted position 73b (see FIG. 21B). When the vertical frame structure 30a further rises, the latch body 60 releases the operating pin 73 and returns the operating pin 73 from the retracted position 73b to the protruding position 73a (see FIG. 21C). Therefore, the latch body 60 does not move from the protruding position 60a.

  In the above-described hanging cabinet 1, the movable frame 3 is accelerated until the movable frame 3 moves from the rising end position 3a to the lowering end position 3b, and then decelerated by the rotary damper 32c to the lowering end position 3b. Thereby, the impact when the movable frame 3 reaches the descent end position 3b can be reduced. Further, the movable frame 3 moves at the speed of lifting by hand until the movable frame 3 is moved from the descending end position 3b to the ascending end position 3a, and then decelerated by the rotary damper 32c to the ascending end position. Thereby, the impact when the movable frame 3 reaches the rising end position 3a can be reduced.

  Further, since the rotary damper 32c does not act until the movable frame 3 is raised and lowered, the movable frame 3 can be moved at a relatively high speed, compared with the case where the damper is acted on the entire rising and lowering. Thus, the switching time from the rising end position 3a to the lowering end position 3b and the switching time from the lowering end position 3b to the rising end position 3a can be shortened.

  In addition, by changing the position of the lower limit protrusion 21a and / or the upper limit protrusion 21b, the position of the movable frame 3 on which the rotary damper 32c acts can be easily adjusted.

  Since the shelf board 4 is stored in the cabinet body 2 at the upright position 4b, the hanging cabinet 1 cannot place an object on the shelf board 4 in the state of being stored in the cabinet body 2. . This has an advantage compared with the conventional hanging cabinet which has a raising / lowering shelf which can be moved up and down in the state which mounted the thing. Specifically, since an object cannot be placed on the shelf plate body 4, the weight of the movable frame 3 and the shelf plate body 4 when moving from the ascent end position 3a to the ascent end position 3b does not substantially change. . In addition, in a hanging door shelf having an elevating shelf that can be moved up and down while an object is placed, the shelf is biased upward in order to reduce the force to lift the shelf even when many objects are placed on the shelf. Therefore, extra force may be required when lowering the shelf. In addition, the lifting operation force changes depending on the weight of the load, which is inconvenient. On the other hand, in the above-described hanging cabinet 1, the weight of the movable frame 3 and the shelf plate body 4 can be designed so that they can be lowered by their own weight, and thereby the movable frame 3 is released by the latch assembly 5. Thus, the movable frame 3 and the shelf plate body 4 can be automatically and unfolded at the lowering end position 4b and the horizontal position without causing an impact.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims. Needless to say, these are also included within the scope of the present invention.

  In the above-described embodiment, it has been described that it is preferable that an object cannot be placed on the shelf plate body 4 stored in the cupboard body 2, but the movable frame 3 and the shelf plate body 4 are moved to the rising end position 3 a and the lowering end position. If the impact when moved to 3b can be relieved, the shelf plate body 4 may be configured to be stored in the cupboard body 2 with an object placed thereon.

  In the above embodiment, it has been described that it is preferable that the movable frame 3 and the shelf plate body 4 can be lowered by its own weight. However, the movable frame 3 and the shelf plate body 4 are moved to the rising end position 3a and the falling end position 3b. If the impact at the time can be reduced, they may be biased upward.

  In the above embodiment, the rotary damper 32c is used between the movable frame 3 and the driven rod 70. However, if there is a damper action due to the relative movement of the movable frame 3 and the driven rod 70, other types such as a gas damper are used. It may be a damper.

  As long as the shelf board 4 can be hold | maintained in the standing position 4b, the combination of the latch pin 60c of the vertical frame structure 30a and the hole 40b of the shelf board 4 may be another form.
