JP 2001-37556 A

In the conventional configuration,
Since the buffer mechanism is an elastic body, when the link comes into contact with the stopper, there is a problem that repulsive vibration occurs, and the storage portion 2 and the storage object constituted by sheet metal parts and the like emit vibration noise.

  In addition, when the storage unit 2 is pulled out to the descending end in a state where no storage items are contained in the storage unit 2, the storage unit 2 such as a spring disposed in the base 1 is urged in the storage direction. The urging force by the urging means to be won has been overcome, and the storage portion 2 has returned to the rising end vigorously, resulting in increased repulsive vibration.

  The present invention solves the above-described conventional problems, and a sufficient shock-absorbing effect can be stably obtained during storage, and the storage part 2 and the storage object composed of sheet metal parts by repulsive vibration do not emit vibration noise. It is an object of the present invention to provide an elevating storage device.

  In order to solve the above-described conventional problems, the lifting storage device of the present invention includes a stopper that restricts the rack body to the storage position, and the stopper includes a speed damping mechanism.

  As a result, the impact when the rack body is stored in the elevating storage apparatus is attenuated by the stopper provided with the speed damping mechanism, and repulsive vibration is not caused when the rack body is stored.

  As is apparent from the above description, the lifting and lowering storage apparatus of the present invention shocks when the rack body is stored is buffered by a stopper having a speed damping mechanism, causing repulsive vibration when the rack body is stored. The user's operational feeling can be improved.

1st invention stores a rack body by contacting the side surface of the rear end side of a rack body, the raising / lowering support mechanism which consists of an arm which supports the said rack body so that raising / lowering is possible, the base which supports an raising / lowering support mechanism A stopper that regulates the position is provided, and the stopper is provided with a direct acting damper as a speed damping mechanism, so that the impact when storing the rack body in the lifting type storage device is caused by the stopper equipped with the direct acting damper. It is damped and does not cause repulsive vibration when the rack body is stored, and the operational feeling of the user can be improved. In particular, in the first invention, since the speed damping mechanism is a direct acting damper, it is possible to obtain a reliable impact damping effect, and no repulsive vibration occurs when the rack body is stored. Can be improved. In addition, since the first invention is provided with a switching mechanism capable of switching the position at which the direct acting damper of the stopper of the first invention acts, the weight of the rack body, the weight of the stored article, or the speed when the rack body is stored. The difference in impact force due to the difference can be adjusted by the switching mechanism. Further, according to the first aspect of the invention, the switching direction of the position by the switching mechanism is a substantially normal direction of the arm rotation.

In the second invention, in particular, the elevating support mechanism of the first invention is a parallel link, and at the retracted position of the rack body, the parallel link is inclined backward from the vertical posture, and the stopper is substantially vertical in the retracted direction. Alternatively, by adopting a configuration in which the direct acting damper works from a range behind the vertical, the effect of the direct acting damper during the storing operation can be sufficiently obtained.

In the third invention, in particular, the storage device of the first or second invention is arranged inside the cabinet having an opening on the front surface, so that the rack body can be moved up and down from the cabinet and stored. It is easy to put things in and out of the cabinet. Further, the direct acting damper does not cause repulsive vibration when the rack body is stored, and the operational feeling of the user can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
As shown in FIGS. 1 to 4, the elevating storage device of this example includes a cabinet 1, a rack body 2 incorporated in the cabinet 1, a front arm 4 that supports the rack body 2 so as to be raised and lowered from the cabinet 1, and a rear side. An elevating support mechanism 3 composed of an arm 5, a base 6 that supports the elevating support mechanism 3, and a stopper 7 that restricts the rack body 2 to the storage position of the cabinet 1 are fixed to the base 6 by holding means such as screws. The stopper 7 is provided with a speed damping mechanism 8. The speed damping mechanism 8 is composed of a linear motion damper 9 that obtains a damping action by the flow resistance of the orifice as a main constituent member.

  The elevating support mechanism 3 pivotally supports the base ends of the front arm 4 and the rear arm 5 with a base 6, and the free ends of the front arm 4 and the rear arm 5 are pivotally attached to the connecting plate 10. The connecting plate 10 is fixed to both side surfaces of the rack body 2.

  In the storage position of the cabinet 1 of the rack body 2, the rear end of the rear arm 5 is in contact with the speed damping mechanism 8 of the stopper 7.

  In addition, the elevating support mechanism 3 constituted by the parallel links tilts the parallel links backward from the vertical posture in the storage position of the rack body 2 in the cabinet 1 and the stoppers are substantially vertical in the storage direction. The speed damping mechanism works from the range behind the vertical.

  A pivot shaft 11 that pivots the rear arm 5 and rotates in conjunction with the rear arm 5 protrudes into the base 6, and an interlocking rotating plate 12 is fixed to the pivot shaft 11 in the base 6. . A tension spring 15 is interposed between the spring hooking hole 13 at one end 12 a of the interlocking rotary plate 12 and the spring hooking hole 14 provided at the upper front end of the base 6, and provided at the other end 12 b of the interlocking rotary plate 12. A direct acting damper 18 is interposed between the support pin 16 and a support pin 17 provided at the upper rear end of the base 6.

  A rotary plate 19 is rotatably supported on the pivot shaft 11, and a tension spring is provided between a spring hook hole 20 at one end of the rotary plate 19 and a spring hook hole 21 provided at the upper rear portion of the base 6. 22 is interposed, and the urging force switching mechanism 23 switches the rotating plate 19 to or from the interlocking rotating plate 12.

  A pivot pin 24 is fixed to the base end portion of the front arm 4, and the pivot pin 24 is rotatably supported by a bearing portion 25 provided on the base 6.

  About the raising / lowering storage apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the rack body 2 is pulled out from the cabinet 1 to the lower front part, when the handle 26 at the lower end of the front end of the rack body 2 is pulled toward the front, the rack body 2 starts from the time when the parallel link is tilted forward from the vertical posture. The effect begins to be accelerated by the self-weight of the rack body 2 and the rotational moment by the stored items stored in the rack body 2, but in the reverse direction by the interlocking rotating plate 12 and the tension spring 15 so as to cancel the rotational moment. Since the dynamic moment acts and the rotational speed is suppressed by the direct acting damper 18, the rack body 2 slowly descends to the descending end.

  On the other hand, when the rack body 2 is raised and stored in the cabinet 1, the rotational moment due to the load of the rack body 2 and the stored item stored in the rack body 2 is offset by the urging force of the tension spring 15, and Since the movable damper 18 has almost no resistance when it is raised by the one-way mechanism, it can be raised and stored relatively lightly. When the rack body 2 is stored, an excessive impact load is generated as an adverse effect of being able to lift it lightly, but the rear arm 5 comes into contact with the speed damping mechanism 8 of the stopper 7, and the linear motion damper 9 of the speed damping mechanism 8 Due to the damping action due to the flow resistance of the orifice, an excessive impact load is absorbed, and the rack body 2 does not cause repulsive vibration.

  Further, when the rotating plate 19 is interlocked with the interlocking rotating plate 12 by the urging force switching mechanism 23, a rotational moment due to the load of the rack body 2 and the stored item stored in the rack body 2 is applied to the tension spring 15, and the rotating plate 19 It is offset by the biasing force of the tension spring 22 interposed between the spring hooking hole 20 at one end and the spring hooking hole 21 provided in the upper rear part of the base 6, and the direct acting damper 18 is raised by the one-way mechanism. Therefore, if the loads of the rack body 2 and the stored items stored in the rack body 2 are equal as compared to when the tension spring 15 is not interlocked, the load can be further raised and stored.

  As described above, in the present embodiment, the stopper 7 that restricts the rack body 2 to the storage position of the cabinet 1 is the speed damping mechanism 8 that includes the linear motion damper 9 that obtains a damping action by the flow resistance of the orifice. By doing so, the shock load at the time of storage is absorbed, and the rack body 2 does not cause repulsive vibration, so that uncomfortable feelings such as vibration sound of the rack body 2 and stored items can be reduced and the user's operational feeling can be improved. .

  Further, in the present embodiment, the lifting support mechanism 3 constituted by the parallel links is configured such that the parallel link is inclined backward from the vertical posture at the storage position in the cabinet 1 of the rack body 2, so that the rack body after storage. The rack body 2 can be prevented from inadvertently popping out of the cabinet 1 due to vibration or the like, and the stopper has a structure in which the parallel link is almost vertical in the retracted direction or the speed damping mechanism works from the range behind the vertical. The speed damping mechanism works in the middle of raising, so that it does not become a burden on the user, and the safety and the user's feeling of operation can be improved.

  Further, a stopper 7 for restricting the rack body 2 provided on the base 6 of the present embodiment to the storage position of the cabinet 1 is provided on the front arm 4 or the rear arm 5 of the lifting support mechanism 3 and the rack body 2 or the base 6 is provided. In particular, when the rack body 2 is pulled out of the cabinet 1, the front arm 4 or the rear arm 5 follows the rack body 2 to reach a position that can be reached by the user. Etc. can be easily performed.

(Embodiment 2)
Next, a second embodiment of the present invention will be described with reference to FIGS. Note that the same components as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only differences are described.

  In the first embodiment, the stopper 7 is fixed to the base 6 with a holding means such as a screw. However, in this embodiment, the base 6 is provided with a long hole 27 and the long hole 27 is provided with a stopper via a slide pin 28. 7 and a damper 9 are held so as to be movable. The elongated hole 27 is formed with a longitudinal surface in a direction substantially normal to the rotation of the rear arm 5 that rotates about the pivot shaft 11.

  The slide pin 28 is pivotally supported by the upper end portion of the link A29 in the base 6, the lower end portion of the link A29 is pivotally supported by the upper end portion of the link B30, and the link B30 is based on an elongated hole 31 formed between both end portions. A link B pin 32 fixed to the base 6 is held so as to be rotatable and movable within the range of the long hole 31. The lower end portion of the link B30 is pivotally supported by the distal end portion of the switching link 33 of the urging force switching mechanism 23.

  About the raising / lowering storage apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In FIG. 9, the urging force switching mechanism 23 shows a state where the rotating plate 19 is not interlocked and the urging force works only on the tension spring 15. At this time, the stopper 7 is held at a position close to the pivot shaft 11 of the elongated hole 27, and the speed damping mechanism 8 constituted by the damper 9 can also obtain the effect at the same position. Next, by moving the switching link 33 in the C1 direction, the urging force switching mechanism 23 is in a state in which the rotary plate 19 is interlocked so that the urging force is applied to the tension spring 22 in addition to the tension spring 15, and the stopper 7 is also linked. B and the link A move in the direction (E1) away from the pivot shaft 11 by the movement of the link A in the directions D1 and E1. When the rack body 2 is stored in this state, the urging force is in a state in which the tension spring 22 works in addition to the tension spring 15, so that there is an advantage that the urging force can be raised more lightly than the case of the tension spring 15 alone. However, as an adverse effect, an excessive impact load is generated. However, the stopper 7 is also moved in the direction (E1) away from the pivot shaft 11, and the distance between the operating point at which the rear arm 5 abuts on the speed damping mechanism 8 of the stopper 7 and the fulcrum (the pivot shaft 11) becomes longer. For this reason, the damping action by the direct acting damper 9 of the speed damping mechanism 8 is also strengthened. Therefore, an excessive impact load is absorbed, and the rack body 2 does not cause repulsive vibration.

  As described above, by adopting a configuration in which the biasing force switching mechanism 23 and the position switching mechanism of the speed damping mechanism 8 are interlocked, the switching of the biasing means is strong, the load in the rack body 2 is small, and the biasing means is reduced. Even if it moves vigorously in the winning storage direction, the position switching mechanism of the speed damping mechanism moves together and the damping mechanism moves to a position where the damping mechanism also works strongly, so that the rack body 2 can be operated by the user without causing repulsive vibration at the storage position. A feeling can be improved.

  In the present embodiment, the switching of the position of the speed damping mechanism is set to the direction substantially normal to the rotation of the rear arm 5 that rotates about the pivot shaft 11, but the switching direction of the position of the speed damping mechanism is the pivot axis. 11, the stroke of contact of the speed damping mechanism 8 with the rear arm 5 of the linear motion damper 9 changes as the rotational direction of the rear arm 5 that rotates about the center 11 changes, and the strength of the speed damping mechanism can be adjusted. The same effect as the embodiment can be obtained.

  Further, in the present embodiment, the urging force switching mechanism 23 and the position switching mechanism of the speed damping mechanism 8 are linked to each other, but a switching mechanism that can switch the position at which the speed damping mechanism 8 acts without interlocking is provided. Therefore, the speed damping mechanism 8 acts on the user or the manufacturing process because of the difference in the impact force when the rack body is stored due to the difference in the weight of the rack body and the assumed weight of the stored items such as the width of the cabinet 1. The position can be adjusted by an adjustment mechanism, and products according to product specifications can be produced without increasing the types of parts.

  As described above, in the elevating storage apparatus and elevating storage cabinet according to the present invention, the impact when the rack body is stored is buffered by the stopper having the speed damping mechanism, and repulsive vibration occurs when the rack body is stored. This makes it possible to improve the user's feeling of operation, so that it can be applied to applications such as storage in various places in a residence, product display stand in a store, etc., in addition to an elevator storage cabinet at a high place in a kitchen.
