Description

  The present invention relates to a shelf-lifting tableware storage that stores a large amount of tableware, for example, in a company or school cafeteria. In particular, shelf lifting tableware storage has the advantage that it can suppress deterioration of the shelf hanging wire, or can prevent protrusion and twisting when the shelf hanging wire loosens, and it is easy to disassemble and reassemble during maintenance etc. Related to storage.

First, the example of the present shelf raising / lowering tableware storage is demonstrated, referring FIG.11 and FIG.12.
FIG. 11: is a partial front view which shows typically the example of the shelf inside the present shelf raising / lowering tableware storage, and a shelf suspension wire, (A)-(D) shows the state at the time of lowering a shelf in time series. FIG.
FIG. 12 is an enlarged view showing details of a connection portion between a shelf and a shelf hanging wire inside the shelf elevating tableware storage shown in FIG. (A) is a front view, (B) is a side view showing a state before lowering the shelf, (C) is a side view showing a state in the middle of lowering the shelf, and (D) is lowering the shelf. It is a side view which shows the state after.

  The shelf T and the shelf suspension wire HW shown in FIG. The shelves T in this example are provided in a total of five levels (the lowest level T1 to the highest level T5). Each shelf T is arranged inside a storage (not shown). The lowermost shelf T1 and the second shelf T2 are fixed at predetermined intervals in the vertical direction inside the storage. The shelf suspension wire HW connects the four corners of the third shelf T3 and the fourth shelf T4, and the fourth shelf T4 and the uppermost shelf T5 vertically. The uppermost shelf T5 is connected to a winding / unwinding mechanism (lifting device) (not shown) via a lifting wire RW. As shown in FIG. 12, the end portion of each shelf suspension wire HW is fixed by crimping to the crimping portion C ′ of the clip C. The clip C is fixed to the left and right end surfaces of the shelves T3 to T5 with screws or the like.

  In the shelf suspended state shown in FIG. 11 (A), the tableware basket B containing the tableware D is disposed in the space between the shelves T1 to T5. As clearly shown in FIGS. 12A and 12B, in this shelf suspended state, the shelf suspension wire HW extends straight up and down. Here, as shown in FIG. 11B, in order to take out the tableware D3 (tableware basket B3) on the third shelf T3, first, the tableware basket on the second shelf T2 is taken out. Then, when the lifting wire RW is lowered, the shelves T3 to T5 are lowered together in a state where they are connected by the respective shelf hanging wires HW, and are stopped when the shelf T3 overlaps the shelf T2. At this time, the interval between the shelves T3 and T2 is, for example, about 70 mm. As described above, the shelves T1 and T2 are fixed and do not move. At this time, the height of the third shelf T3 is just high for human work.

  Furthermore, when it is desired to take out the tableware D4 (tableware basket B4) on the fourth shelf T4 (see FIG. 11C), or when it is desired to remove the tableware D5 on the top shelf T5 (FIG. 11D). In the same manner as in the case of the third shelf T3, the lifting wire is lowered after taking out the lower tableware basket. Thus, when the shelves T4 and T5 are lowered, as shown in FIGS. 12 (B) → (C) → (D), the shelf hanging wires HW connecting the shelves T3 and T4 and T4 and T5 are straight. It gradually relaxes in a loop from the state.

  Here, since the end W ′ of the shelf suspension wire HW is fixed by the crimping portion C ′ of the clip C, the upper shelf is overlapped with the lower shelf as shown in FIG. When it reaches, it bends sharply. Therefore, there is a problem that the end portion W ′ of the shelf suspension wire HW is likely to deteriorate as the lifting and lowering operation of the shelf is repeated. Alternatively, when the shelf hanging wire HW is slacked in a loop shape, the protruding direction of the slack portion (the middle portion between the clips C of the shelf hanging wire HW) is not regulated, so the protruding slack portion is complicatedly twisted. There were also problems such as tangling and getting caught inside the storage.

For example, Patent Literature 1 and Patent Literature 2 are known literature examples of this type of shelf elevating tableware storage.
The “shelf elevating tableware disinfection storage machine” disclosed in Patent Document 1 (Japanese Patent Laid-Open No. Hei 6-263213) includes a plurality of (in this example, four stages) shelf boards. Each shelf board is supported via a suspension member in the shelf frame of the storage machine. This suspension member mainly consists of a chain, and moves up and down by an elevating drive device installed in the storage machine. Each shelf board moves up and down in the shelf frame as the suspension member moves up and down. Elevating brackets are attached to the four corners of each shelf board. The metal fittings for raising and lowering are different in shape from the first to fourth shelf boards. The raising / lowering metal fittings of the uppermost (fourth) shelf are directly fixed to the suspension member. Holes with different shapes are formed in the metal fittings for raising and lowering the lower (third to first) shelf plates, and a suspension member is passed through these holes.

  On the other hand, four rod-shaped hanging fittings (locking members) corresponding to the lifting and lowering fittings of the respective shelf plates are incorporated in the hanging member at regular intervals. The fourth (uppermost) hanging bracket is fixed to the lifting bracket on the fourth shelf board. The third hanging bracket passes through the holes of the first-stage and second-stage shelves, and hits the third-stage shelves. The second hanging bracket passes through the hole of the lifting / lowering bracket of the first-stage shelf board, and hits and locks against the lifting / lowering bracket of the second-stage shelf board. The first (bottommost) hanging bracket hits the lifting bracket on the first shelf and is locked.

  In this storage machine, when the shelf plate is raised, the suspension brackets of the suspension members are respectively brought into contact with the corresponding holes of the lifting bracket and locked, so that each shelf plate is arranged at predetermined intervals. On the other hand, when the shelf is lowered, the suspension fitting of the suspension member passes through the hole of the lifting and lowering fitting of the lower shelf so that the suspension fitting is not bent between the shelf boards. However, in this storage machine, the lifting metal fittings at the four corners of each shelf plate and the hanging metal fittings (locking members) must be formed individually, which increases processing man-hours and processing costs. There is a drawback that the whole manufacturing cost increases.

  The “shelf elevating device” disclosed in Patent Document 2 (Japanese Patent Application Laid-Open No. 8-38267) includes a plurality of (in this example, four stages) shelf boards arranged in a shelf frame. Inside the shelf frame, rotatable screw shafts are provided at the four corners of each shelf board. The four corners of the uppermost shelf are attached to each screw shaft via screw nuts. The four corners of the lower (third to first) shelf are attached to each screw shaft via a thrust bearing. Each shelf board is connected by a connecting member. The connecting member includes a chain wire that is passed up and down between the screw nut and the thrust bearing of each shelf plate, and a spring that connects these chain wires in the lateral direction. Or the connection member can also use the X-shaped foldable stay attached between the screw nut and the thrust bearing of each shelf board. In the document 2, since this apparatus does not use a strong bracket or the like, it is said that there are advantages such as easy assembly, a simple structure, and a low apparatus price.

  In this apparatus, when raising each shelf board, each screw shaft is rotated in one direction (forward direction). Then, a screw nut moves up along each screw axis, and this raises the uppermost shelf. As the uppermost shelf rises, the lower (third to first) shelf connected to this via a connecting member rises sequentially. On the other hand, when lowering each shelf board, each screw shaft is rotated in the other direction (reverse direction) contrary to the above, and the uppermost shelf board is lowered. At this time, when the connecting member is a chain wire and a spring, the chain wire that has slackened as each shelf plate is lowered is attracted by the elasticity of the spring. For this reason, unlike the case described above with reference to FIGS. 11 and 12, there is no problem that the slack portion of the chain wire protrudes or is twisted in a complicated manner. Alternatively, when the connecting member is an X-shaped stay, a slack portion such as a chain wire does not occur in the first place, and thus the problem described with reference to FIGS. 11 and 12 does not occur.

  According to the apparatus of Patent Document 2, the problem described with reference to FIGS. 11 and 12 can be solved. However, this apparatus uses a screw shaft, a screw nut / thrust bearing, a connecting member, and the like as an elevating mechanism for the shelf board. Therefore, the structure is complicated as compared with the type described with reference to FIGS. 11 and 12, and the installation of the screw shafts on the four sides of the shelf plate increases the size of the entire apparatus and increases the manufacturing cost. . Alternatively, in the case of using an X-shaped stay as a connecting member in this apparatus, there is a drawback that it is difficult to disassemble and reassemble during maintenance or the like.

In this case, since the ring (eye end) at the end of the shelf hanging wire is rotatably fitted to the shaft protruding from the side of the shelf, the attachment / detachment of the connecting portion can be easily performed. . Therefore, for example, during maintenance, the shelf and the shelf suspension wire can be separated and cleaned to every corner. Or, if some of the shelves in multiple stages or some of the multiple shelves are deteriorated or damaged, only the deteriorated or damaged parts need to be replaced, and the entire shelves and shelves are replaced. You do n’t have to.

In the shelf raising / lowering tableware storage of this invention, it can have a means to prescribe | regulate the rotation direction of the connection part by the side of said shelf suspension wire.
By defining the rotation direction of the wire connecting portion using this means, the wire can be slackened in a desired direction, and the slackened wire can be stored in a desired space in the storage. Therefore, the possibility that the wire is bent or entangled in a complicated manner can be further reduced.

  According to the present invention, it is possible to suppress the deterioration of the shelf hanging wire, or to prevent the protruding and twisting when the shelf hanging wire is loosened, and to lift and lower the shelf having advantages such as easy disassembly and reassembly during maintenance. A tableware storage can be provided.

On the surface of the partition plate 15, there is provided an operation panel 15 </ b> P for operating the winding / unwinding mechanism 60 described in detail later.

  As shown in FIGS. 3 and 4, inner plates 17 (17 </ b> A and 17 </ b> B) are provided inside the left and right side walls 10 </ b> A of the main body 10. The central inner plate 17A is formed larger, and smaller inner plates 17B are arranged on both sides of the inner plate 17A. A gap 17S along the vertical direction is opened between the inner plate 17A and each inner plate 17B. Inside each gap 17S, shelf connecting portions 41 provided at the four corners of the shelf T are respectively arranged (details will be described later). As shown in FIG. 4, a space S exists between the left and right side walls 10 </ b> A and the left and right inner plates 17. This space S serves as a blower duct in the storage 1 when the blower 19 (see FIGS. 2 and 3) at the top of the main body 10 is operated, and a wire when a later-described shelf suspension wire 30 is loosened. Also serves as a placement space.

2 to 5 show the internal structure of the main body 10.
A shelf T (see FIG. 4) is arranged in the main body 10. The storage 1 of the present embodiment is provided with a total of eight shelves T (the lowest level T1 to the highest level T8) (see FIGS. 2, 3, and 5). The lowermost shelf T1 and the second shelf T2 (fixed shelf) are placed inside the left and right side walls 10A of the main body 10. Four corners of the third shelf T3 to the uppermost shelf T8 (moving shelf) are connected to the shelf suspension wire 30 (FIG. 6) at the connection portion X (wire connection portion 31 and shelf connection portion 41: see FIGS. 7 and 8). (See below). The uppermost shelf T8 is connected to the lifting wire 59. The lifting / lowering wire 59 is wound up / down by a winding / unwinding mechanism 60 (see FIG. 9), and the moving shelves T3 to T8 are moved up and down accordingly. The mechanism 60 is disposed on the upper inner plate 10B (see FIGS. 2 and 3) on the upper side inside the storage 1.

Hereinafter, the internal configuration of the main body 10 will be described in detail mainly with reference to FIGS. 4 to 9.
As shown in FIG. 4, the shelf T includes an outer peripheral frame 21 in which a vertical frame 22 along the front-rear direction and a horizontal frame 23 along the left-right direction are assembled into a rectangle. A plurality (11 in this example) of pipes 25 are installed between the lateral frames 23 of the outer peripheral frame 21. These pipes 25 are installed in parallel with each other at predetermined intervals. Of the eight shelves T1 to T8 in total, near the four corners of the movable shelves T3 to T8, the vertical frame 22 is provided with a shelf connecting portion 41 described later. A stopper 28 (see FIGS. 2 and 5) is provided on the uppermost moving shelf T8. The stopper 28 is for defining the maximum height of the tableware placed on the uppermost shelf T8. The stopper 28 is configured to touch an upper limit switch (not shown) when the uppermost movable shelf T8 is raised to the upper limit position or more due to a control trouble of the winding / unwinding mechanism 60 or the like. When the stopper 28 touches the upper limit switch, the hoisting / unwinding mechanism 60 stops and the moving shelves T3 to T8 stop.

  FIG. 6 shows a shelf suspension wire 30 that connects the movable shelves T3 to T8. The shelf suspension wire 30 is made of stainless steel as an example. Wire connection portions 31 are provided at both ends of the shelf suspension wire 30. Each wire connection portion 31 includes a clip 33 and an eye end 35. The clip 33 has an inner hole 33a into which one end of the shelf hanging wire 30 is inserted on one end side (wire connection side), and a protrusion 33b on the other end side (eye end connection side). The eye end 35 is a ring-shaped member having a center hole 35a, and an engagement hole 35b is formed in a part of the side surface. The protrusion 33b of the clip 33 is engaged with the engagement hole 35b of the eye end 35, and both corners are welded and the like. The end of the shelf suspension wire 30 is inserted into the inner hole 33a of the clip 33, and the outside of the clip 33 is crimped by being crimped.

  7 and 8 show a configuration of the connection portion X (a state where the wire connection portion 31 provided on the shelf suspension wire 30 and the shelf connection portion 41 provided on the shelf T are connected). The shelf connecting portion 41 is provided on the side surface of the vertical frame 22 near the four corners of the outer peripheral frame 21 of the shelf T (see FIG. 4). The connection shaft 43 of the shelf connection portion 41 is a three-stage shaft, and includes an eye end mounting shaft portion 43a, a central angular shaft portion 43b, and a male screw shaft portion 43c. As shown in FIG. 7, the eye end mounting shaft portion 43 a and the central angular shaft portion 43 b protrude outward from the side surface of the vertical frame 22 (left side in FIG. 7A), and the male screw shaft portion 43 c It penetrates the side surface of the frame 22 and protrudes inward (the right side in FIG. 7A).

  The eye end attachment shaft portion 43a has a circular cross section, and the center hole 35a of the eye end 35 of the wire connection portion 31 is rotatably inserted. The axial length of the eye end mounting shaft portion 43a is at least twice the thickness of the eye end 35 (see FIG. 7A). The central angular shaft portion 43b has a square cross section (see FIG. 8), and is formed between the eye end mounting shaft portion 43a and the male screw shaft portion 43c. The male screw shaft 43c has a male screw cut on the outer peripheral surface. A nut 49 is fastened to the male screw shaft portion 43 c penetrating the side surface of the vertical frame 22 via a flat washer 47 and a spring washer 48.

  On the outer surface of the vertical frame 22, a U-shaped detent plate 51 (see FIG. 8) is fitted around the central angular shaft portion 43b. The detent plate 51 is fixed to the vertical frame 22 with rivets 52. The rotation prevention plate 51 prevents the central angular shaft portion 43b having a square cross section from rotating, thereby preventing the connection shaft 43 from rotating relative to the vertical frame 22 (that is, the shelf T). A resin plate 53 is disposed on the upper surface of the central angular shaft portion 43b. A spring 58 is disposed on the resin plate 53. The resin plate 53 and the spring 58 are pressed from above by the presser plate 55. Both plates 53 and 55 and the spring 58 are fixed to the central angular shaft portion 43 b with screws 56. The resin plate 53 contacts the edge of each gap 17S (see FIGS. 3 and 4) between the inner plates 17A and 17B. A C-ring 57 is detachably mounted near the end of the eye end mounting shaft 43a (see FIG. 7). The C-ring 57 prevents the eye end 35 from coming off from the end of the eye end mounting shaft 43a.

  As shown in FIG. 7B, the spring 58 has an annular fulcrum 58a through which the screw 56 passes. A spring arm portion 58b extends from the fulcrum portion 58a to the wire connecting portion 31 side (left side in FIG. 7B). The tip 58c of the spring arm portion 58b is slightly curved along a part of the outer peripheral surface of the clip 33. The spring arm portion 58b biases the clip 33 in the arrow α direction. 7B corresponds to the left rear connection portion X of the shelf T in FIG. The arrow α direction in FIG. 7B indicates the direction of the space S ′ shown in FIG. In the space S ′, two of the front side of the four corners of the shelf T are the rear side of the connection portion X, and two of the rear sides of the four corners of the shelf T are the front side of the connection portion X.

  In a state where the shelf suspension wire 30 is stretched (a state where the movable shelves T3 to T8 are suspended), the wire tension exceeds the urging force of the spring 58, and the clip 33 of the wire connection portion 31 rises vertically. When the shelf suspension wire 30 is loosened and the wire connection portion 31 is rotated around the eye end attachment shaft portion 43a, the clip 33 receiving the urging force of the spring 58 is pushed in the direction of the arrow α and falls down. As described above, the spring 58 plays a role of defining the turning direction of the wire connecting portion 31. As described above, the rotation direction (arrow α direction) of the wire connecting portion 31 is the space S ′ direction in FIG. 4, and the slack hanging wire 30 is the space S (between the left and right side walls 10A and the left and right inner plates 17). Therefore, the possibility that each shelf hanging wire 30 is bent or entangled in a complicated manner can be reduced.

  As shown in FIG. 4, inside the storage 1, the connecting shaft 43 of each shelf connecting portion 41 has a central angular shaft portion 43 b inside each gap 17 </ b> S between the inner plates 17 </ b> A and 17 </ b> B (see FIGS. 3 and 4). The eye end attachment shaft 43a (and the shelf suspension wire 30 attached thereto) are arranged in the space S. When the movable shelves T3 to T8 move up and down, the resin plate 53 contacts the edge of each gap 17S between the inner plates 17A and 17B, and the movable shelves T3 to T8 are prevented from shaking. Each gap 17S serves as a movement guide when the movement shelves T3 to T8 move up and down.

  FIG. 9 schematically illustrates a winding / unwinding mechanism 60 that lifts or lowers the movable shelves T <b> 3 to T <b> 8 in the storage 1 by winding or unwinding the lifting wire 59. The mechanism 60 includes a pair of winding rollers 61 and 62 around which a lifting wire 59 is wound. These winding rollers 61 and 62 are fixed to both ends of the rotation center shaft 63, respectively. The rotation center shaft 63 is supported by a pair of support brackets 65. A bearing 67 is interposed between the rotation center shaft 63 and the support bracket 65. A sprocket 69 is fixed to the rotation center shaft 63 between the support brackets 65. An output shaft 73a of a geared motor 73 with a brake is connected to the sprocket 69 via an annular chain 71. Instead of using the sprocket 69 and the annular chain 71, a geared motor with a brake can be directly connected to the outside of the rotation center shaft 63, and the rotation center shaft 63 can be directly rotated by driving the motor.

  Two circumferential grooves (V-shaped grooves) are formed on the circumferential surfaces of the winding rollers 61 and 62, respectively. Lifting wires 59A and 59B are wound around the two circumferential grooves of the winding roller 61, and lifting wires 59C and 59D are wound around the two circumferential grooves of the winding roller 62, respectively. The end of the lifting wire 59A of the winding roller 61 and the end of the lifting wire 59C of the winding roller 62 are each drawn out directly downward. The end of the elevating wire 59B of the winding roller 61 and the end of the elevating wire 59D of the winding roller 62 are each pulled out in the lateral direction, wound around pulleys 75 and 76, and pulled out directly downward. A connecting fixture 59a (see FIGS. 2 and 5) is provided at each end of the four lifting wires 59A to 59D. The connecting portion X ′ in the uppermost movable shelf T8 has a connection fixture 59a of the lifting wire 59 fixed to the shelf connecting portion 41 and a wire connecting portion 31 of the shelf hanging wire 30 that connects the movable shelves T8 and T7. It differs from the other connection part X by the point attached rotatably.

  Sensors 77 and 78 for detecting loosening of the wire are arranged in the middle of drawing the lifting wire 59B of the winding roller 61 and the lifting wire 59D of the winding roller 62 in the lateral direction. These sensors 77 and 78 detect slack of the lifting wires 59B and 59D that occur when the moving shelves T3 to T8 are clogged or the wire is pulled out even after reaching the lower limit position. When the sensors 77 and 78 are activated, the rotational drive of the geared motor 73 with brake is stopped.

  The winding / unwinding mechanism 60 can be operated by operating the operation panel 15P (see FIG. 1) of the main body 10. When the geared motor 73 with brake is driven to rotate in the forward direction, the sprocket 69 rotates in the forward direction via the annular chain 71. At the same time, the rotation center shaft 63 and the winding rollers 61 and 62 are also rotated in the forward direction. Rolled down. At this time, the moving shelves T3 to T8 descend. On the other hand, when the geared motor 73 with brake is driven to rotate reversely, the sprocket 69 is rotated reversely via the annular chain 71, and at the same time, the rotation center shaft 63 and the winding rollers 61 and 62 are also rotated reversely to move the lifting wires 59A to 59A. 59D is rolled up. At this time, the moving shelves T3 to T8 rise.

Next, the operation of the storage 1 of the present embodiment will be described.
FIG. 10 is an enlarged view showing details of a connection portion between the shelf inside the bookshelf elevating tableware storage and the shelf hanging wire. (A) is a front view, (B) is a side view showing a state before lowering the shelf, (C) is a side view showing a state in the middle of lowering the shelf, and (D) is lowering the shelf. It is a side view which shows the state after.
2 and FIG. 3, in the space between the shelves T1 to T8, a tableware basket containing tableware is arranged in the same manner as described above with reference to FIG. As clearly shown in FIGS. 10A and 10B, in this shelf suspended state, the shelf suspension wire 30 that connects between the lower-stage movable shelf and the upper-stage movable shelf extends straight up and down.

  Here, when moving the movable shelves T3 to T8 from the shelf suspended state, the operation panel 15P (see FIG. 1) on the surface of the partition plate 15 of the main body 10 is operated, and the geared with brake of the hoisting / unwinding mechanism 60 is operated. The motor 73 (see FIG. 9) is driven. When the motor 73 is driven and the lifting / lowering wire 59 is unwound from the winding rollers 61 and 62, the moving shelves T3 to T8 start to be integrally lowered while being connected by the shelf hanging wire 30, and then the moving shelf T3 is moved. It stops so as to overlap the upper surface of the fixed shelf T2. In the same manner, the moving shelves T4 to T8 are stopped so as to be sequentially overlapped.

  In the process in which the movable shelf T4 overlaps the upper surface of the movable shelf T3, the shelf suspension wire 30 connecting the movable shelves T3 and T4 is attached to the vertical frame 22 of the shelf T as shown in FIGS. It slackens to form an almost semicircular loop. Specifically, when the shelf suspension wire 30 is loosened, the wire connection portion 31 receiving the urging force of the spring 58 (see FIG. 7) is connected to the eye end mounting shaft of the connection shaft 43 of the shelf connection portion 41 when the shelf suspension wire 30 is loosened. It rotates to the side (space S 'side of FIG. 4) which falls in the horizontal direction around the part 43a. As the wire connection portion 31 rotates, the shelf suspension wire 30 gradually relaxes so as to form a substantially semicircular loop along the vertical frame 22 of the shelf T within the space S ′ of FIG. 4. Go. Hereinafter, even when the moving shelves T5 → T6 → T7 → T8 sequentially overlap the upper surface of the moving shelf T4, each shelf hanging wire 30 is also semicircle along the vertical frame 22 of the shelf T within the space S ′. Loosen like a loop.

  As described above, in the main storage 1, when the moving shelves T <b> 3 to T <b> 8 are lowered, the wire connection portion 31 of the shelf hanging wire 30 biased by the spring 58 rotates around the connection shaft 43 of the shelf connection portion 41. Then, it is loosened so as to form a semicircular loop within the space S ′ in the main body 10. Therefore, the shelf suspension wire 30 is not bent in a complicated manner and protrudes into the storage 1 and is not caught between the shelves T. Moreover, as shown in FIG.10 (D), when the wire connection part 31 of the shelf suspension wire 30 rotates, the edge part of the shelf suspension wire 30 is not bent at an acute angle, and an excessive force is not applied. Therefore, the possibility of deterioration or damage at the end of the shelf suspension wire 30 can be reduced.

  On the other hand, in order to return the lowered moving shelves T3 to T8 to the suspended state shown in FIGS. 2 and 3, the operation panel 15P (see FIG. 1) on the surface of the partition plate 15 of the main body 10 is operated, and the hoisting and unwinding operations are performed. The geared motor 73 with a brake (see FIG. 9) of the mechanism 60 is driven in the opposite direction. Then, as the motor 73 is driven, the lifting / lowering wire 59 is wound around the winding rollers 61 and 62, and the movable shelves T3 to T8 start to rise integrally. At this time, the wire connection portion 31 of the shelf hanging wire 30 rises vertically around the eye end attachment shaft portion 43a of the connection shaft 43 of the shelf connection portion 41 against the biasing force of the spring 58 (see FIG. 7). It returns to the state extended straight from the substantially semicircular loop up and down (FIG. 10 (D)-> (C)-> (B)).

  In addition, the structure of the connection part X of a present Example becomes a structure which the eye end 35 of the wire connection part 31 fitted so that rotation with respect to the connection axis | shaft 43 of the shelf connection part 41 was possible. The wire connection part 31 can be easily attached / detached by attaching / detaching the C-ring 57 (see FIG. 7). Therefore, for example, during maintenance, the moving shelves T <b> 3 to T <b> 8 and the shelf hanging wire 30 can be separated to clean the interior of the storage 1 to every corner. Alternatively, when a part of the moving shelves T3 to T8 or a part of each shelf hanging wire 30 is deteriorated / damaged, only the deteriorated / damaged part needs to be replaced, and the entire shelf and the shelf hanging wire are exchanged. There is also an advantage that it is not necessary.

Next, another embodiment of the present invention will be described.
FIG. 13: is an enlarged view which shows the detail of the connection part of the shelf inside a shelf raising / lowering tableware storage and shelf hanging wire which concern on the other Example of this invention. (A) is a front view, (B) is a side view showing a state before lowering the shelf, (C) is a side view showing a state in the middle of lowering the shelf, and (D) is lowering the shelf. It is a side view which shows the state after standing.
A wire connecting portion 31 ′ at the lower end of the shelf hanging wire 30 shown in FIG. 13 includes a clip 33 and an eye end 35 ′. The clip 33 is the same as that shown in Fig. 6 and the like, but the eye end 35 'is different from that shown in Fig. 6 and the like in that an eccentric portion 35 "is formed. The wire connecting portion 31 at the upper end portion of 30 is the same as that of the above-described embodiment.

  The eccentric portion 35 ″ is formed so as to protrude from a part of the outer peripheral surface of the ring-shaped member. The shelf suspended state shown in FIGS. 13 (A) and 13 (B) (the lower shelf and the upper shelf) In the state in which the shelf suspension wire 30 that connects them extends straight up and down), the eccentric portion 35 ″ projects laterally to the space S ′ side in FIG. 4 (left side in FIG. 13B). 13 (B) to 13 (D), the center of gravity of the eccentric portion 35 ″ is indicated by the symbol G. The eccentric portion 35 ″ defines the rotational direction of the wire connecting portion 31 ′, and the shelf hanging wire It plays the role of loosening 30 in a desired direction (space S ′ direction in FIG. 4).

  Similarly to the case described above with reference to FIG. 10, when the movable shelves T3 to T8 are lowered from the shelf suspended state, the movable shelf T3 stops so as to overlap the upper surface of the fixed shelf T2, and then the movable shelves T4 to T8 are sequentially moved. Stop to overlap. In the process in which the upper shelf T overlaps the upper surface of the lower shelf T, if the tension of the shelf suspension wire 30 connecting these two shelves is loosened, the eye end 35 ′ of the wire connection portion 31 ′ has an eccentric portion 35 ″. 13 (B) → (C) → (D), the wire connecting portion 31 ′ rotates about 90 ° around the connecting shaft 43 counterclockwise in the figure. The shelf suspension wire 30 gradually loosens so as to form a substantially semicircular loop along the vertical frame 22 of the shelf T within the space S ′ (see FIG. 4).

  According to this embodiment, the rotational weight is applied to the eye end 35 ′ by the weight of the eccentric portion 35 ″, and the shelf suspension wire 30 can be loosened in a desired direction. It can be accommodated in a desired space (space S ′ in FIG. 4). When the eye end 35 ′ having the eccentric portion 35 ″ as described in the present embodiment is used, the spring 58 shown in FIG. be able to.
