Description

  The present invention relates to a storage system that is fixed to a wall, and more particularly to a storage system that has an elevating mechanism that is attached to a wall near the ceiling above the eye. In particular, it is suitable for storage requiring a light and large volume.

  Storage furniture is often placed on the floor. Increasing the amount of furniture that occupies the floor increases the storage capacity, but reduces the floor area and creates a sense of narrowness and pressure. For this reason, there are many pieces of furniture that are short from the waist down. This is because there is no furniture at the height of the line of sight and you can see the wall, so there is little sense of narrowness, but the amount of storage is reduced accordingly. There is also storage above the person's height, such as suspending top bags and shelves. The amount of storage increases accordingly, but since it is higher than the line of sight, it cannot be seen far away, and there are many cases where a platform is required, which is not convenient.

  Although a liftable storage shelf has been invented, it is large and complicated. A balance raising / lowering type storage shelf with a weight is conceivable. One is a system in which weights of the same weight as the stored shelves are coupled to both ends of the string via pulleys. This pulley is a pulley in which the pulley housing is fixed without moving the shaft, and is called a fixed pulley. According to this, a constant force can be obtained regardless of the amount of movement of the shelf. However, the height of the weight + the amount of movement of the weight is necessary. If a large amount of movement of the shelf is desired, the whole becomes large accordingly.

  A balance-type lift-type storage shelf with a weight, in which a pulley is attached so that the weight moves up and down as a moving pulley, and a movement amount of 4 is reduced, has been invented. A pulley utilizing the fact that a force that is n times the tension of the string on the pulley of the pulley is generated when the pulley casing is attached is called a moving pulley. A method of using the movable pulley will be described with reference to FIGS. 14 (b) and 14 (c). 14B and 14C correspond to n = 2 and n = 4, respectively. The number n of the strings pulling the pulley of the moving pulley becomes a multiple of the force, and at the same time, the moving amount of 1 / n of the string can be the moving amount of the weight connected to the moving pulley. As a result, a constant force can be obtained regardless of the amount of movement of the storage box 2, and at the same time, even when the amount of drawer of the storage box 2 is the total length L of the storage box 2, No worries about getting bigger. However, the weight required for this is increased by a factor of n, and the overall weight increases accordingly, and there is a concern that the load on the wall to which the weight is attached becomes too large.

  This will be described with reference to FIG. The storage system includes an outer box 1, a pair of storage boxes 2 a and 2 b, a gap 3, a weight 4, a moving pulley 5, a box string 6, a fixed pulley 8, and a slide rail 9. The outer box 1 has a downward opening 1a to which a slide rail 9 that can be pulled out downward is attached. The pair of storage boxes 2 a and 2 b are built in the outer box 1 and can be stably pulled down from the opening 1 a by the slide rail 9. A gap 3 is provided in a vertical method between the outer box 1 and the pair of storage boxes 2 a and 2 b, and a weight 4 is disposed in the gap 3. The weight 4 is connected to the housing of the movable pulley 5. A box string 6 is wound around the pulley of the movable pulley 5, and a pair of storage boxes 2 a and 2 b having box attachment portions 2 c and 2 d are attached to both ends of the box string 6. The box string 6 is guided to the moving pulley 5 by the fixed pulley 8 and reverses the direction of the force so that the force of the weight 4 applied to the moving pulley 5 and the force of the pair of storage boxes 2a and 2b are attracted to each other. FIG. 2A shows the dynamic state at this time. Assuming that the weights of the stored storage boxes 2a and 2b are W, respectively, the weight 4 is in a balanced state when the weight is 2W. FIG. 2 (b) shows the force relationship of the moving pulley.

  When only the storage box 2a is pulled downward from the state where both the storage boxes 2a and 2b are at the upper fulcrum, the storage box 2b maintains the position of the upper fulcrum, so the box string of the storage box 2b is fixed to the top plate of the outer box 1 It does not change mechanically. That is, when one storage box is pulled, the pulley of the movable pulley rotates and the weight is pulled up, and when one storage box is pulled out by the entire length L of the storage box, the weight is lifted by L / 2. The mechanical behavior is the same as that of the conventional (b) shown in FIG. The same applies to the case where the storage box 2a is returned to the upper fulcrum and the storage box 2b is pulled out, that is, the storage box 2 can be doubled and the storage amount can be doubled. In terms of the amount of storage, the weight of a conventional 1/2 weight is sufficient. At this time, even if the entire length L of the storage box 2a or the storage box 2b is pulled out, the moving amount of the weight 4 is L / 2, so if the height of the weight 4 is set to L / 2 or less, the moving amount of the weight 4 + the weight 4 Since the total height can be less than or equal to L, the height of the outer box 1 can be minimized. Moreover, as shown in FIG. 1, the dynamic structure except the storage box 2 can be collected on the back plate 1b of the outer box 1, and can be modularized.

  Instead of reversing the direction of the force from the storage box 2, the force from the weight 4 may be reversed. As shown in FIG. 3, in order to use a fixed pulley, a weight string 7 is provided. The weight 4 is connected to the casing of the movable pulley 5 via the fixed pulley 8 by the weight string 7, and the direction of the force of the weight 4 is reversed. FIG. 4A shows the dynamic state at this time. FIG. 4B shows the force relationship of the moving pulley. As is clear from the comparison with the force relationship of the moving pulley in FIG. 2B, the entire figure is only turned 180 degrees. The balance of force is the same, and the operation of the storage box 2 is the same. That is, when one storage box is pulled, the pulley of the movable pulley rotates and the weight is pulled up, and when one storage box is pulled out by the entire length L of the storage box, the weight is lifted by L / 2.

  Only differences from the second embodiment will be described with reference to FIG. The gap 3 is a pair of gaps 3a and 3b, the weight 4 is a pair of weights 4a and 4b, and the weight string 7 is composed of a pair of weight strings 7a and 7b. A weight 4 a disposed in the gap 3 a is connected to one end of the weight string 7 a and is connected to the casing of the movable pulley 5 via the fixed pulley 8. Similarly, the weight 4b arranged in the gap 3b is connected to one end of the weight string 7b and connected to the housing of the movable pulley 5 via the fixed pulley 8. When the weight string 7a and the weight string 7b are coupled in the vicinity of the movable pulley 5, a weight string coupling portion 7c is provided, and the weights 4a and 4b are arranged to be attracted to each other by the weight string coupling portion 7c. FIG. 6 shows the dynamic state as described above. When the pair of storage boxes 2a and 2b are pulled out exclusively, as in the first embodiment, the pulley of the moving pulley 5 rotates and the moving pulley pulls up the weight. The dynamics when viewed with a moving pulley are the same as those in Example 2 as shown in FIG. That is, when one storage box is pulled out by the total length L of the storage box, the pair of weights is lifted by L / 2.

  As can be seen from FIG. 6 (a), the pair of weights 4a and 4b can be attracted to each other even before the pair of storage boxes 2a and 2b are attached. Thereby, even if there is no storage box 2a, 2b, since it balances only with the weights 4a, 4b, the storage box 2 can be made detachable easily. During the installation work, the storage box 2 can be removed for installation work, and nailing and screwing can be performed on the empty outer box 1 for easy handling. During use, the storage box can be removed for cleaning. Furthermore, since the weight 2W of the weight 4 can be distributed in two places, the volume of each weight 4a, 4b can be made small and thin, and it can be utilized even in a narrow gap. As shown in FIG. 4, the mechanical structure excluding the storage box 2 can be integrated into the back plate 1b and can be modularized.

  For example, the weight string coupling portion 7c may be connected via a connected ring as shown in FIG. That is, it only means that the weight string connecting portion 7c is mechanically connected, and a plurality of members are also included in the present invention.

  There is also a method in which the weight 4 and the moving pulley are paired. 8 and 9 will be described in comparison with the first embodiment. The gap 3, the weight 4, the moving pulley 5 and the box string 6 are respectively composed of a pair of gaps 3a and 3b, a pair of weights 4a and 4b, a pair of moving pulleys 5a and 5b, and a pair of box strings 6a and 6b. Box ends 6e and 2f are provided at both ends of the box string 6a, and box attachment portions 2g and 2h are provided at both ends of the box string 6b. A pair of space | gap 3a, 3b is a position of a pair of side wall which opposes. The box string 6a is wound around the pulley of the movable pulley 5a via the fixed pulley 8, has box attachment portions 2e and 2f at both ends, and is connected to the pair of storage boxes 2a and 2b. Similarly, the box string 6b is wound around the pulley of the movable pulley 5b via the fixed pulley 8, and has box attachment portions 2g and 2h at both ends and is connected to the pair of storage boxes 2a and 2b. Weights 4a and 4b are connected to the casings of the movable pulleys 5a and 5b, respectively. In order to couple the box string 6a and the box string 6b, a box string coupling part 6c is provided in the vicinity of the box mounting parts 2e and 2g of the storage box 2a, and a box string coupling part is disposed in the vicinity of the box mounting parts 2f and 2h of the storage box 2b. 6d is provided. The box string coupling portions 6c and 6d attract and balance the weights even when there is no storage box 2a or 2b. When one storage box is pulled, the pulleys of the pair of movable pulleys 5a and 5b rotate at the same time, the pair of weights 4a and 4b are pulled up at the same time, and when one storage box is pulled out by the total length L of the storage box, the weight is L Raised by / 2.

  Since the weight is balanced even before the storage box is attached, the storage box can be easily attached and detached as in the fourth embodiment. The installation box can be removed for installation work, and installation work can be performed, and nailing and screwing can be performed on the empty outer box, making it easy to handle. Moreover, the storage box 2 can be removed and cleaned during actual use. Furthermore, since the weights of the weights can be distributed in two places, the volume of each weight can be made small and thin, and can be utilized even in a narrow gap. In addition, compared with Example 1 and 2nd form, the load to a pulley is half. In Example 4, the string force is half W / 2 in any pulley, and the load on the pulley is reduced accordingly, and a long life can be expected. Further, even if there is no one of the pair of storage boxes, as shown in FIG. 8, the weight strings are attracted to each other by the action of the box string coupling portions 6c and 6d, and even when there is only one storage box, it can operate as it is.

  The box string coupling portions 6c and 6d may be constituted by three strings and may be connected via a ring similar to that shown in FIG.

  FIG. 10 shows an embodiment in which a pair of storage boxes 2a and 2b are provided at the front and rear. Even in this case, the mechanical state is the same as that in FIG. That is, there are the same operations and effects as in the fourth embodiment.

  The module 13 shown in FIGS. 9 and 10 will be described with reference to FIG. FIG. 11 shows a state in which the module 13 is attached to the outer box 1. The four fixed pulleys 8 on both sides of the module 13 drive the strings that pull the pulleys of the movable pulleys 5a and 5b. Thereby, the direction of the moving pulleys 5a and 5b is changed by 90 degrees compared to the direction of the fixed pulley 8. In determining the thickness of the module 13, the thickness of the roller of the moving pulley is taken into consideration in addition to the strength of the module. 11 (a) and 11 (b), only the position of the fixed pulley 8 on the way is different. Symbol A indicates the position of the box mounting portion of the storage box. In FIG. 11A, the central symbol A of a pair of pulleys having a predetermined interval is shifted by the width of the storage box 2 on the back and front, and the position of the storage box 2 is as shown in FIG. It is. FIG. 11B shows an example in which the center symbol A of a pair of pulleys having a predetermined interval is arranged in the center on both the back and the front.

  FIG. 12 is a three-side view showing the relationship between the module and the pulley. By providing a mounting hole so that the position of the fixed pulley attached in the middle of the module 13 can be selected, it is possible to cope with both when using the fourth embodiment and when using the fifth embodiment. That is, the fixed pulley 8 can be attached to the position of FIG. 12 (a) or (b) as necessary.

  It is effective to allow the additional weight 4 to be added to the weight 4. For example, what is necessary is just to design so that when the additional weight 4 is added in the height direction, the upper limit of the weight 4 height limit is set. Further, the thickness may be set to be less than the upper limit of the thickness when the additional weight 4 is added in the thickness direction. There is also a method of magnetizing the weight 4 when adjusting the weight 4 in this way. That is, if the weight 4 is made of a ferromagnetic material such as iron and is magnetized, the added weight 4 is attracted and the one-touch weight 4 can be attached and detached.

  It is effective to attach a lower point holding mechanism or a brake mechanism in which the storage box 2 does not start unless a predetermined force is applied upward when the storage box 2 is fully pulled out. When a slide rail is used, a slide rail that originally has this function may be used, or a mechanism that performs this function may be provided.

  When closing, a soft closing type slide rail may be used that has a built-in mechanism in which the last stroke reduces the rail speed by a damper. Regarding the balance between the stored storage box 2 and the weight 4, the weight 4 is made slightly heavy. As a result, a force to always close the storage box 2 is applied, so that the speed is accelerated when it starts to close, but it is always gently closed at the end.

  The storage box 2 may be guided by a slide rail so that the storage box 2 is pulled out slightly diagonally. When the storage system of the present invention is installed in the space above the window, when the handle of the lock of the window is greatly extended forward, and the storage box 2 comes down directly below, the storage box 2 is Attach the slide rail so that it pulls out slightly forward instead of pulling it down. Thus, when the storage box 2 is pulled out, projections that can be an obstacle to the back wall can be avoided, and the present invention can be implemented.

  Although the present invention has been described with respect to operation with no power source, it may be combined with an electric machine. That is, when the storage box 2 is moved up and down by a motor and gears, the weight 4 and the storage box 2 are generally balanced, so that the motor torque can be reduced accordingly. Also, the motor and gears may be able to obtain a braking action.

  FIG. 13 shows a study diagram of a women's shoe storage system as an example of the storage system of the present invention. This is a shoe storage system specializing in lightweight women's shoes among shoes, and is installed in addition to existing shoe storage furniture. Is. Since many women's shoes are small and light, they are suitable for the storage system of the present invention. A plurality of storage systems of the present invention are used as modules. The entire storage box 2 of the present invention shown in FIG. 7 is used as three modules. The right two are used for boots, the middle two are used for women's shoes, and the left two are used for indoor wear such as slippers. This is a system study. As in this example, a plurality of modules can be freely combined to meet individual needs, and a flexible design is possible.
