Description

  The present invention relates to a storage / removal device for storing and taking out articles in a high storage location.

  There is a device that lifts a heavy object from a low position to a high position, moves it to a stable position at a high place, and then lowers it from a high position to a low position convenient for movement when necessary. For example, the liftable storage device of Patent Document 1 is a liftable storage device for using an altitude space such as an upper space of a refrigerator or furniture, and maintains the posture of the inner box from the outer box using a parallel link. The box is structured to protrude forward and then move downward. A slide member is required to use a combination of rotation by the link mechanism and lateral movement by the groove cam.

The vehicle elevating device of Patent Document 2 is for getting on and off a wheelchair, connecting a support arm to a parallel link, further connecting a platform to the support arm, and rotating the parallel link with a hydraulic drive unit, The platform is moved forward and then moved downward. In order to sufficiently move the platform downward, the parallel link is rotated by that amount, so that there is a difficulty that the platform protrudes greatly forward due to the length of the link.
The transfer device disclosed in Patent Document 3 incorporates a movable frame body and a vertical rail into a horizontal rail of a fixed frame body in a pull-out manner so that the movable frame body can be lowered along the vertical rail at the pulled-out position. In this structure, when the movable frame is forward and downward, the second horizontal rail protrudes above the movable frame.

  The futon storage device of Patent Document 4 has a structure in which an arm that can be lifted and lowered forward is provided inside a closet. It is stated that it is not necessary for the worker to lean forward when placing a futon on a closet shelf (working at a high place) or lowering it from a shelf (working at a low place). It is not effective when divided into stages.

In Japan, there are many people who use futons for sleeping. Since the futon can be easily stored using a closet, the futon can be stored in the closet during the daytime to widen the living space and can be used for various purposes.
However, raising and lowering futons requires physical ability such as strength and flexion, so when you get older, it will be difficult to raise and lower daily because of the decline in physical strength. In addition, inns, etc., it is necessary to raise and lower a large number of futons every day. However, it is difficult to secure a workforce and the aging of employees is progressing, making it difficult to maintain the futon raising and lowering services. It's getting on.

JP-A-7-67726 Japanese Patent Laid-Open No. 7-61276 Japanese Patent Laid-Open No. 5-3808 Japanese Patent Laid-Open No. 6-154051

It is an object of the present invention to provide an apparatus that can be placed in a high storage place and can easily put in and out the stored goods with little effort.
In the structure of Patent Document 1, the number of parts is large and the cam is also expensive. The structure of Patent Document 2 is unsuitable for use in a small space because it protrudes forward.
Further, in the structure of Patent Document 3, the second horizontal rail protruding upward is extremely dangerous when taking in and out the stored items.
It should be noted that when handling futons as stored items, the high place storage and removal device is called a futon storage device, but such high place storage and removal device is in the living space, has no particular discomfort, is safe, And it must be able to be provided at low cost.

It is assumed that a frame to be fixed at a storage location located at a high place, a basket for loading stored items, a guide member, and a load reducing auxiliary device or driving device are provided.
A horizontal guide part is provided on the upper side of the frame side wall part, and a vertical guide part is provided on the front side. A wire or a chain is hung around the horizontal guide part and the vertical guide part via a driving pulley and a driven pulley, and a basket is coupled thereto. . The basket is sized to fit into the frame. The basket can be pulled out of the frame by hand or by driving the wire in a circulating manner, and can then be moved down the front surface of the frame. On the contrary, it is assumed that it can move from the lower side to the upper push-in upper position and can move into the frame.

The basket is supported by the frame by engaging an upper fulcrum and a lower fulcrum provided at the rear end of the upper side with the rail of the guide. At the same time, movement in the front-rear and up-down directions is guided.
An auxiliary device and a driving device for reducing the load are coupled to the wire. That is, in the case of a structure in which the basket is moved manually, the labor (load) of the moving operation is reduced by the auxiliary device connected to the drive pulley of the wire, and in the case of the structure in which the basket is automatically performed, the drive device is used.

By assembling a box-shaped basket on a box-shaped frame, the maximum storage capacity of the storage area at a high place can be utilized.
Since the basket is linearly moved back and forth and up and down with respect to the box-shaped frame, the basket does not unnecessarily protrude to the front of the closet and can be used in a compact manner.
Since the frame and basket, the guide member, and the wire and auxiliary member or drive member can be used, the structure is simple and robust. Further, since an expensive member such as a cam is not required, it can be provided at a low cost.
Since an auxiliary device or a drive device that reduces the load is used to move the basket, the labor of raising and lowering the stored items is reduced.

First, the case where a drive device is used will be described.
FIG. 1 shows a state in which a futon storage device 3 according to an embodiment of the present invention is arranged in an upper stage 2 (storage place located at a high place) of the closet 1. In addition, normally, the futon storage device 3 has a width dimension that is almost half of the width of the upper part of the closet, because the futon is used without opening up the closet that closes the closet. Shall. Further, the futon storage device 3 is one of high place storage / removal devices using the stored items as futons.
The closet 1 is divided into an upper stage 2 and a lower stage 5 by a shelf 4. This is a normal close-in structure. The closet 1 is opened and closed by a reed 6 with a front face. Therefore, the maximum opening width of the closet 1 is the width of one ridge (usually about 900 mm). Reference numeral 7 is an upper rail, and reference numeral 8 is a lower rail (sill).

  The futon storage device 3 includes a frame 9, a basket 10, a guide member 12, and a drive device 13. The frame 9 is configured by assembling steel materials in a box shape, and the height, width, and depth are dimensions that fit in the upper stage of the closet 1. The upper and front sides of the frame 9 are open. The frame 9 is arranged in the upper stage of the closet 1 and is fixed in the closet 1 with the sticks 14 disposed on both sides of the rear part of the upper side. The basket 10 has a box-like structure formed by joining aluminum pipes, and the upper and front sides are also open. The basket 10 should be as light as possible, but strong enough to withstand the load of the futon. The height, width, and depth of the basket 10 are dimensions that fit into the frame 9.

  As shown in FIGS. 1 to 3 or FIGS. 4 to 6, the basket 10 is moved horizontally from the state in the frame 9 to the front of the frame 9, and further vertically moved downward from the front position. The structure can be moved from the lower position to the position that fits in the frame 9 by tracing the position and the reverse. A bottom plate 11 (FIG. 7) made of synthetic resin and made into a sawtooth shape is stretched on the bottom surface of the basket 10.

The guide member 12 is arranged on the left and right side wall portions 15 and 16 of the frame 9 with the same configuration but symmetrical arrangement (12a and 12b). Hereinafter, one guide member 12 will be described, and the other member is assumed to be arranged symmetrically on the left and right.
The guide member 12 includes an L-shaped substrate 17 and an L-shaped rail 18 formed by smoothly connecting a horizontal portion and a vertical portion. The substrate 17 is sturdy and formed of a steel plate having a thickness of about 6 mm. The rail 18 is fixed to the substrate 17 with the horizontal portion of the rail 18 aligned with the horizontal portion of the substrate 17 and the vertical portion of the rail 18 aligned with the vertical portion of the substrate 17. These constitute a guide member 12 having a horizontal guide portion 19 and a vertical guide portion 20 as a whole. The rail 18 is a sturdy one formed by bending a steel material having a U-shaped cross section, and the groove-shaped bottom wall is fixed to the substrate 17 with the open side of the U-shaped cross section directed to the side.

  That is, the guide member 12 is an integral guide in which a horizontal guide part 19 is arranged on the upper side of the side wall part 15 in the frame 9, a vertical guide part 20 is arranged on the front side, and a horizontal guide function and a vertical guide function are continuously arranged. It is a member. The rail 18 further comprises an upper fulcrum rail 18a and a lower fulcrum rail 18b. The upper fulcrum rail 18a is provided on one surface of the substrate 17, the lower fulcrum rail 18b is provided on the other surface, and the upper fulcrum is provided on the horizontal portion. The rail 18a for the upper fulcrum is positioned above the rail 18b for the lower fulcrum, and the upper fulcrum rail 18a is positioned rearward of the rail 18b for the lower fulcrum in the vertical portion.

  On the other hand, a U-shaped reinforcing member 23 having a triangular shape that is long in the front-rear direction in a side view with a large rear vertical dimension is fixed to the rear end of the upper side of the left and right side wall portions 21, 22 of the basket 10. To do. An upper fulcrum roller 24 and a lower fulcrum roller 25 are provided inside the rear part of the reinforcing member 23 by shifting the upper fulcrum roller 24 upward and rearward with respect to the lower fulcrum roller 25 (FIG. 5). . Since the reinforcing member 23 is U-shaped in cross section, the U-shaped groove portion is arranged so as to cover the side wall portion 15 of the frame 9, and the upper fulcrum roller 24 on the inner surface of the rear end portion is placed in the U-shaped groove of the upper fulcrum rail 18a. The lower fulcrum roller 25 is engaged with the U-shaped groove of the lower fulcrum rail 18b to support the load of the basket 10 at this portion and to be movable by the roller. That is, the basket 10 is supported by the guide member 12 of the frame 9 at the rear end portion of the upper side of the left and right side wall portions 21 and 22.

  The shift distance between the upper fulcrum rail 18 a and the lower fulcrum rail 18 b in the horizontal guide portion 19 of the guide member 12 is substantially equal to the vertical distance between the upper fulcrum roller 24 and the lower fulcrum roller 25, and the vertical guide of the guide member 12. The shift interval between the upper fulcrum rail 18 a and the lower fulcrum rail 18 b in the portion 20 is substantially equal to the vertical distance between the upper fulcrum roller 24 and the lower fulcrum roller 25. As a result, the basket 10 is stored in the frame 9 (FIG. 1), moved horizontally along the guide member 12 and moved to the front of the frame 9 (FIG. 2), and then moved from that position to a position below the frame 9. And can move continuously. The reverse is also possible.

At this time, the upper fulcrum roller 24 rolls in contact with the upper groove wall and the front groove wall of the upper fulcrum rail 18a, and supports one of the loads due to the rotational moment of the basket 10 by the upper fulcrum roller 24. The fulcrum roller 25 rolls in contact with the lower groove wall and the rear groove wall of the lower fulcrum rail 18b, and supports the other load caused by the rotational moment of the basket 10.
The left and right side wall portions 15 and 16 of the frame 9 have a driving pulley 26 at the rear end portion of the horizontal guide portion 19, and driven pulleys 27 and 28 at the front end portion of the horizontal guide portion 19 and the lower end portion of the vertical guide portion 20, respectively. Are arranged, and a wire 29 is circulated around them (FIG. 3). Reference numeral 30 denotes an adjustment pulley.

  The rear end portion of the upper side of the basket 10 is coupled to the wire 29 (joint portion 31 FIG. 6), and the output shaft of the transmission gear 32 of the drive device 13 is coupled to the drive pulley 26. The transmission gear 32 is connected to a general-purpose DC motor 33. The drive of the motor 33 can be operated by a control device 35 having an operation unit 34 (FIG. 1). The drive pulley 26 is of a winding type, and can be circulated in either the forward or reverse direction by being driven by the motor 33.

  Therefore, when the motor 33 is driven in the forward direction from the operation portion 34, the basket 10 is moved along the guide member 12 along with the circulation of the wire 29, and is moved forward from the frame 9, that is, the press-up upper stage 2, and then moved downward. . By stopping the driving of the motor 33, the basket 10 can be stopped at an arbitrary position, and the position can be maintained by the lock function of the transmission gear 32. When the basket 10 moves horizontally, the reinforcing member 23 having a U-shaped cross section on the basket side moves while sandwiching the upper side of the substrate 17 to prevent the basket 10 from swinging left and right.

Actually, there is almost no need to stop the basket 10 in the middle of the horizontal movement in the close-up upper stage 2, and what is necessary is the middle of the vertical movement, and the futon is taken out from the basket 10 or loaded with the futon. In many cases, it is stopped at a height that is convenient for the operation (average of about 800 mm from the floor surface to the top surface of the futon loaded). For this reason, in this embodiment, the top surface of the futon loaded in the basket 10 is detected by the photosensors s1 and s2 (FIG. 1) attached to the frame 9, and the operation unit 34 and the control device 35 The basket 10 is automatically stopped so that the top surface is always at a position of 800 mm from the floor surface. When the futon is not loaded, it is stopped by detecting the surface of the bottom plate 11 of the basket 10.
The operation unit 34 includes “out”, “end”, “down”, and “up” buttons.

  When the “eject” button of the operation unit 34 is pressed, the motor 33 is driven to move the wire 29 in the forward direction, and the basket 10 stored in the upper presser foot 2 slides forward from the upper presser foot 2, Move down and stop at a position where you can easily take it out. For this reason, the labor of taking out the futon is greatly reduced. Further, when the upper futon loaded from the basket 10 is taken out, the top surface of the futon becomes the top surface of the next futon, so that the level is lowered. The basket 10 is rotated in the reverse direction, and the basket 10 is raised to a position where the top surface of the futon to be taken out is detected and stopped. That is, the loaded futon can always be easily taken out.

  When all the futons of the basket 10 are taken out, the “end” button of the operation unit 34 is pressed. Then, the control device 35 ignores the signals from the photosensors s 1 and s 2, reverses the motor 33, and stores the basket 10 in the frame 9. The position where the basket 10 is accommodated in the frame 9 is detected by a limit sensor s3 disposed at the rear end of the guide member 12.

  In order to store the futon in the closet 1, first, the “put out” button of the operation unit 34 is pressed, and the empty basket 10 is moved to the front of the closet 1 from the close upper stage 2. The basket 10 is stopped at a height convenient for placing the futon by the sensors s1, s2 and the control device 35. When a single futon is loaded and the level of the top of the futon rises, press the “lower” button on the operation unit 34 to automatically bring the top of the futon to a height convenient for loading the futon on it. Lower. When all the futons are loaded, the “suck” button of the operation unit 34 is pressed to place the frame 9 in the upper part of the closet 1. In this way, it is always possible to carry out the futon with a light effort.

  It is troublesome to lower the futon from the basket 10 located in front of the closet 1 or to operate the operation unit 34 every time it is loaded. Until the "" button is pressed, the top surface position of the futon may be automatically maintained at the height from the floor surface (800 mm in this embodiment) set according to the removal of the futon and stacking. .

  As another embodiment, the driving device 13 may be replaced with an auxiliary device that reduces the load, such as a balancer using a spring, instead of active driving by the motor 33. In this case, the basket 10 is moved manually, but the load when the basket 10 is moved vertically is reduced by the spring force, so that the basket 10 can be put in and out lightly. It can be used as a simple and inexpensive futon storage device.

The material constituting the basket 10 is not limited to an aluminum pipe but may be a resin pipe. In the case of using the motor 33, the means for moving and stopping the basket 10 and the mode of control are not limited to those described above. The height from the floor on which the basket is stopped may be adjusted according to the height of the operator.
The wire 29 is not limited as long as it is coupled to the rear end of the basket 10 and can circulate in the forward and reverse directions, and may be a rope, a belt, or a chain.
As described above, the futon storage device 3 has been specifically described as an embodiment of the high place storage / removal device. However, the high place storage device is not limited to this, and taking into account the overall dimensions and strength, It can be used for storing and taking out books, and for storing and taking out cargo in warehouses.
