【Example】 Next, one embodiment of the present invention will be described based on the drawings. In the drawing, 1 is the room A box-shaped storage rack installed on the ceiling 10 of the storage rack 1, with a An opening 1a is provided for taking things in and out, but the opening 1a is , so as to be opened and closed by a door 3 whose upper end is hinged to the storage rack 1 via a hinge 2. It's getting old. In addition, on the rear surface 1b of the storage rack, there are A fitting portion 1g is formed to fit vertically slidably into the guide rail 4 of the storage rack. The tool 1 can be moved up and down along a guide rail 4.

[0006] Reference numeral 5 denotes a drive device assembled to the bottom surface 1c of the storage rack, and the drive device 5 is The pair of elevating motors 6 and 7 are equipped with gears that rotate forward and backward as the motors are driven. Wheels 6a and 7a are interlocked and connected, respectively. Also, 8 and 9 are the same on the left and right. A pair of lifting wires, the left and right lifting wires 8 and 9 are provided with spiral teeth on their outer peripheries. It is formed from a so-called geared wire and is connected to both the gear wheels 6a and 7a. While meshing, the tips of the lifting wires 8 and 9 are connected to the ceiling surface 1d of the storage rack 1. A mounting bracket 10a is attached to the ceiling 10 side through the through holes 1e provided at both left and right ends. The structure is such that the storage rack 1 is suspended by being fixed to the storage rack 1 through the . That is, noboru As the lowering motors 6 and 7 are driven, the left and right lifting wires 8 and 9 are laid on the bottom surface 1c. accommodated in the provided outer tubes 8a, 9a, or the outer tubes 8a, By receiving the transfer action from 9a, the storage rack 1 is moved to the storage rack on the ceiling side. It is designed to move up and down between the storage position and the lowered take-out position, but the left side lift The gear wheel 8 meshes with both gear wheels 6a and 7a from the rear side, and also connects to the right side lifting wire. 9 meshes with both gear wheels 6a and 7a from the front side, which allows the gear wheels to This prevents unbalanced loads from acting on the wheels 6a and 7a, and also This prevents overload from acting on the motors 6 and 7.

[0007] Further, 11 is an opening/closing motor, and a gear is interlocked with the opening/closing motor 11. Left and right opening/closing wires 12 are engaged with the front and rear wheels 11a. this The opening/closing wire 12 is made of a geared wire like the lifting wires 8 and 9. The opening and closing motor 11 is driven in the forward and reverse directions, and the The tip of each opening/closing wire 12 is fed out and returned from the tube 12a. , left and right arms 1 whose tips are rotatably supported 13a at both left and right ends of the door 3; 3 are integrally connected to the proximal end portions of each. The arm 13 is connected to the storage rack 1 is slidably supported on both left and right sides 1f of the By feeding out and retracting the opening/closing wire 12, the front upper or rear lower The door 3 is opened and closed by sliding.

[0008] Furthermore, 19 is a control section incorporated in the drive device 5, and the control section 19 is , via a cord reel (not shown) that winds up the power cord hanging from the ceiling 10. The lift motors 6 and 7 and the opening/closing motor The forward/reverse drive control for 11 is as follows. In other words, the microcomputer The control unit 19 configured using a user includes a lifting operation switch 20 and a lowering operation switch 20. operation switch 21, stop operation switch 22, rack upper limit position detection switch 23, Rack lowering position detector 24, door open position detecting switch 25, door closing position detecting switch 26. Signals from various switches and setting devices such as rack lowering position setting device 27 are input. Based on these input signals, the lifting motors 6, 7, Outputs control commands to component devices such as the opening/closing motor 11, the acoustic speaker 28, and the illuminator 29. I'm starting to do that. In addition, the operation switches 20, 21, and 22 should be placed at appropriate positions on the frame. The rack upper limit position detection switch 23 is arranged on the ceiling surface 1d of the storage rack 1. When the storage rack 1 reaches the ceiling storage position, it is detected by contacting the ceiling 10. In addition, the rack lowering position detector 24 is configured to detect, for example, the lifting motor 6. It can be a motor rotation speed detector built into either one of , 7, and the door opening/closing position. Position detection switches 25 and 26 are provided on the guide rod 14, and The position setting device 27 is composed of something like a variable resistor, and is connected to the bottom surface 1c of the rack. It is set up so that it can be exposed to a wide range of conditions, and can be set freely. Furthermore, 1f is an inspection device detachably attached to the storage rack 1 to cover the drive device 5 from below. It's a lid.

[0009] These control procedures are, for example, as shown in the illustrated flowchart. wife The system starts when the power switch is turned on, and the initial settings are completed. Then, it is determined whether either the ascending or descending operation switches 20 and 21 have been operated. When the lift control switch 20 is turned on, the lift control is activated. When the subroutine is entered and the lowering operation switch 21 is turned on, the lowering operation switch 21 is turned on. The system now moves to the descending control subroutine. In addition, the stop operation switch 2 When 2 is operated, a stop signal is output with priority over both controls described later, and the drive is stopped. It is beginning to be stopped.

0010 The rise control subroutine is set as follows, for example. In other words, the door The door close position detection switch 26 detects whether or not 3 is closed, and the door is in the closed state. In other words, if it is determined that it is in an open state including half-open, the A closing drive control command is output to the motor 11, and a door closing position detection switch is output. 26 detects the door open state, the opening/closing motor 11 is driven to close. At this time, It is preferable to output a light-off command to the illuminator 29. In this way, the closing of door 3 is detected. When the upper limit position detection switch 23 detects the upper limit position of the lifting motors 6 and 7, A rise command is output until the Then, as storage rack 1 reaches its upper limit position, Drive stops.

[0011] Further, the descending control subroutine is set as follows, for example. In other words, The storage rack 1 is located at the position set by the rack lowering position setting device 27. A decision is made as to whether or not to do so. This judgment is based on the set value of the setting device 27 and the This is done by comparing and determining the detected value of the position detector 24. and setting position When it is determined that the location is higher than the The descending drive command is issued until the set value of the setting device 27 and the detected value of the detector 24 match. output and lower the storage rack 1 to the set lowering position. At this time, the sound It is preferable to consider safety by activating the voice organ 28 to alert the surroundings. Delicious. When storage rack 1 has been lowered to the set lowering position in this way, the opening/closing motor An open drive command is issued to the door open position detection switch 25 until the door open position detection switch 25 detects an open position. Powered. Then, when the door 3 is opened, a lighting command is output to the illuminator 29. Ru.

0012 In the embodiment of the present invention constructed as described above, the lowering operation is performed as described above. When the switch 21 is operated downward, the storage rack is moved as the lifting motors 6 and 7 are driven. 1 will be lowered to the appropriate position, and then adjust the timing to the end of the lowering of storage rack 1. The opening/closing motor 11 is driven to open the door 3. On the other hand, the operating switch for raising When the door 20 is raised, the opening/closing motor 11 is reversely driven to close the door 3, and then When the door 3 is closed, the lifting motors 6 and 7 are reversely driven to store the door. This will increase Luck 1.

[0013] In this way, in the present invention, in order to make effective use of dead space, the storage rack 1 Although the storage rack 1 is provided on the ceiling 10, the storage rack 1 can be lowered as needed. Moreover, the front door 3 will open automatically in the lowered position. . Therefore, when putting things in and out of ceiling storage, it is no longer necessary to use a ladder or stepladder every time. It is easy to use without the hassle of having to go up and down ladders or stepladders while carrying things. You can easily and safely take things in and out.

[0014] Moreover, in this device, the lowering position of the rack 1 is determined by the rack lowering position setting device 27. can be adjusted freely by setting the You can make people respond to your needs. This lowering position adjustment is performed by moving the storage rack 1 This is guaranteed by the structure in which it is suspended by lifting wires 6 and 7. Moreover, in this device, the guide rail 4 guides the user to move up and down. This prevents storage rack 1 from swinging sideways and allows for smooth lifting and lowering. Ru.

[0015] Also, the lifting wires 8 and 9 are connected to both gear wheels 6a and 7a, respectively. This prevents uneven loads from acting on the gear wheels 6a and 7a. It is also possible to avoid overloading one of the lifting motors 6 and 7. Then, only one of the lifting motors 6 and 7 stopped due to overload and the storage rack 1 was tilted. It is also possible to reliably prevent problems such as failure.

[0016] Furthermore, the drive device 5 is assembled on the bottom surface 1c of the storage rack 1 side, not on the ceiling part 10 side. Because it is attached, inspections, etc. can be done without the need for a ladder or stepladder. This can be done extremely easily from a low position by simply lowering the inspection lid and removing the inspection lid 1f. It also has excellent maintainability.

[0017] It should be noted that the present invention is of course not limited to the above-mentioned embodiment, and the lowered position of the door 3 This can also be done by moving the limit switch up and down according to the lowered position. can. Also, with this product, do not continue to press and operate the lowering operation switch. can be set so that it can be lowered beyond a set position, in this way By doing so, you can improve maintainability and also make it easier to put in and take out heavy items. This means that the storage rack 1 can be lowered close to the floor surface when doing so.

[0018]

[effect]

In summary, since the present invention is constructed as described above, the elevating drive means As the storage rack is driven, the storage rack lowers to the appropriate position, and then the storage rack finishes lowering. The opening/closing drive means is activated at the same timing to open the door. Therefore, Although a storage rack is installed in the ceiling to make effective use of dead space, , the storage rack can be lowered if necessary, and in the lowered position the front The door will open automatically. Therefore, when taking things in and out of the ceiling storage, , instead of preparing a ladder or stepladder one by one as in the past, or using a ladder or stepladder while holding an object. It is extremely easy and safe to take things in and out without the hassle of going up and down. I can do that.

[0019] Moreover, in this device, the lowering position of the rack is caused by the operation of the lifting drive means. It is determined by the amount of moving wire that is fed out, and therefore it is suitable for tall and short people. It is possible to adapt the system to the optimal state for each individual user. It becomes.
