Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a movable ceiling storage cabinet installed in a house or the like.

[Prior Art and Problems to be Solved by the Invention] Today, it is difficult to secure sufficient storage space in houses and the like, so effective use of dead space has been proposed. Therefore, one idea is to install a storage compartment in the ceiling where it does not get in the way of daily life, but in this case, it is necessary to prepare a ladder or stepladder each time you put things in, and also to climb up the ladder or stepladder while holding the items. This meant that loading and unloading items would be hard work, and there was also the risk of safety issues.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a movable ceiling storage that can eliminate these drawbacks. A storage rack equipped with an opening/closing door is configured to be raised and lowered by the telescopic operation of a suspension member suspended from the ceiling, and an extension limit position is set in advance between the ceiling and the storage rack, and A telescopic elevating guide member whose lower end side is connected to the storage rack is interposed to allow the storage rack to move up and down to a predetermined range exceeding the extension limit position, and the storage rack is further provided with The present invention is characterized by being provided with an opening/closing link mechanism that closes and opens the opening/closing door as the door moves up and down within a predetermined range exceeding .

According to the present invention, with this configuration, it is possible to take things in and out of the ceiling storage extremely safely and easily without using a ladder or a stepladder.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, 1 is a storage rack;
An opening 1a for putting things in and out is formed in the front surface of the holder, and the opening 1a is opened and closed by a door 3 whose upper end is hinged to the storage rack 1 via a hinge 2. It has become.

Reference numeral 4 denotes a drive device assembled to the bottom surface 1b of the storage rack 1, and the drive device 4 includes a pair of drive motors 5.
Gear wheels 5a and 6a, which rotate in forward and reverse directions when driven by a motor, are installed inside the gear wheels 6, respectively. Further, 7 and 8 are a pair of left and right wires, and each of the left and right wires 7.8 is formed by a so-called geared wire having spiral teeth on the outer periphery, and meshes with the gear wheels 5a, 6a. The storage rack 1 is suspended by being locked to the ceiling part 9 side. That is, the drive motor 5
．． 6, the left and right wires 7.8 are accommodated in the outer tubes 7a, 8a laid on the bottom surface 1b of the storage rack 1, or are fed out from the outer tubes 7a, 8a, thereby moving the left and right wires 7.8 into the storage rack 1. moves up and down, but the left wire 7 meshes with both gear wheels 5a, 6a from the rear side, and the right wire 8 meshes with both gear wheels 5a, 6a from the front side. This prevents an unbalanced load from acting on the gear wheels 5a, 6a, and also prevents an overload from acting on one of the drive motors 5.6.

Furthermore, 1o is a motor control unit incorporated in the drive device 4, and the motor control unit IQ receives power supply via a cord reel 12 that winds up a power cord 11 hanging from the ceiling 9. However, forward/reverse driving and stopping of the drive motor 5.6 is controlled by a lift operation switch (not shown).

This is performed based on signals from wire limit switches 13, 14, which detect the feeding limit positions of the left and right wires 7.8, respectively, as well as signals from an upper limit switch 15 and a lower limit switch 16. Note that 17 is a removable inspection lid that covers the drive bag @4 from below.

On the other hand, reference numeral 18 denotes a pair of left and right lifting guide members. Each lifting guide member 18 is constructed by interposing a telescopic pantograph-type link part 21 between upper and lower brackets 19 and 20. is fixed to the ceiling part 9, while the lower bracket 20 is connected to the storage rack 1 to provide a steady guide when the storage rack 1 goes up and down. is adjustable and is connected to the storage rack 1 in a relationship that allows the storage rack 1 to be moved up and down to a predetermined range exceeding the extension limit position. That is, in the long holes 19a and 20a of the upper and lower brackets 19.20 formed to guide the front link end 21a of the link part 21 so as to be able to move back and forth, there is a stopper that restricts the rearward movement of the front link end 21a at a selected position. 22, the extension limit position can be adjusted.Also, a plurality of elongated holes 20c are formed in the vertical direction in the connecting plate 20b extending downward from the lower bracket 20. By loosely fitting a plurality of supporting shafts 23 protruding from the side surface of the storage rack 1 into the elongated holes 20c, the storage rack 1 can be raised and lowered within a predetermined range exceeding the extension limit position of the lifting guide member 18. It has become.

Further, reference numeral 24 denotes an opening/closing link mechanism provided on the side surface of the storage rack 1, and a first link 25 constituting the opening/closing link mechanism 24 has an intermediate portion near the base end protruding from the side surface of the storage rack 1. The roller 25a provided at the tip of the third link 25 is supported by a guide rail 3a provided vertically on the rear surface of the door 3. They fit together so that they can be transferred freely.

In other words, the roller 25a is configured to roll within the guide rail 3a as the first link 25 swings upward, thereby pushing the door 3 toward the open position. Furthermore, the opening/closing link mechanism 24 includes a second link 27, one end of which is pivotally connected to the base end of the first link 25, one end of which is pivotally connected to the other end of the second link 27, and an intermediate portion of which is housed. A third link 29 is pivotally supported by a pin 28 protruding from the side surface of the rack 1, and a fourth link 30 whose one end is pivotally connected to the other end of the third link 29 is provided. The other end of 30 is connected to the connecting plate 20b on the lifting guide member 18 side via a pin 31.
It is pivotally connected to. That is, when the storage rack 1 moves up and down within a predetermined range exceeding the extension limit position of the lifting guide member 18, a relative movement occurs between the storage rack 1 and the connecting plate 20b, and as a result, the fourth link 30 The opening/closing link mechanism 24 is operated by being pushed or pulled.

In an embodiment of the invention constructed as described.

When the lift operation switch is operated downward, the recess 9 in the ceiling 9
The storage rack 1 located inside the storage rack 1 is lowered by the wire 7.8 being fed out as the motor is driven, and in this state the door 3 is in the closed position and the support shaft 23 of the storage rack 1 is lowered.
is a connecting plate 20b to receive the load of the lifting guide member 18.
It comes into contact with the upper end of the elongated hole 20c. When the elevating guide member 18 reaches the pre-adjusted extension limit position, the elevating guide member 18 stops extending, while the storage rack 1 continues while the support shaft 23 moves downward through the elongated hole 20c of the connecting plate 20b. The lowering is continued by 20 seconds, and here the lifting guide member 18
A relative movement occurs between the storage rack 1 and the storage rack 1, and the door 3 is automatically opened by the opening/closing link mechanism 27.

On the other hand, when the lift operation switch is operated to raise, the drive motor 5.6 is driven in reverse to raise the storage rack 1. However, at the beginning of the lift, the lift guide member 18 does not contract and only the storage rack 1 rises. The opening/closing link mechanism 27 automatically closes the door 3 based on the relative movement between the lifting guide member 18 and the storage rack 1 caused by this.

As described above, in the present invention, although the storage rack 1 is provided on the ceiling part 9 in order to make effective use of dead space, the storage rack 1 can be lowered as necessary, and moreover, the storage rack 1 can be lowered as needed. Then the front door 3 will open automatically. Therefore, when taking things in and out of the ceiling storage, there is no need to prepare a ladder or stepladder each time, or go up and down a ladder or stepladder while holding the object, as in the conventional case.

This makes it extremely easy and safe to put things in.

Moreover, the lowering limit position of the storage rack 1 can be freely adjusted, and since the door 3 will automatically open and close at the adjusted lowering limit position, the items will always be placed in the optimal position regardless of the ceiling height. It can be put in and taken out, and as a result, it can be highly versatile without being restricted in its mounting location.

Furthermore, the wire 7.8 that suspends the storage rack 1 and the lifting guide member 18 that guides the storage rack 1 to keep it steady are housed in the storage rack 1 when it is raised to the ceiling 9. Even if a large lifting stroke is ensured, there is no problem such as the wire 7.8 or the lifting guide member 18 being exposed to the outside and becoming a hindrance or spoiling the appearance.

In addition, since the left and right wires 7.8 are meshed with both gear wheels 5a and 6a, respectively, the gear wheels 5a and 6a are meshed with each other.
, 6a can prevent unbalanced loads from acting on the drive motors 5. and 6a, thereby allowing smooth lifting.
It is also possible to prevent an overload from acting on the storage rack 1, thereby reliably preventing problems such as only one of the drive motors 5 and 6 stopping due to overload, causing the storage rack 1 to tilt.

Furthermore, since the drive device 4 is assembled to the bottom surface 1b of the storage rack 1 side rather than the ceiling part 9 side, inspections can be carried out by lowering the storage rack 1 and removing the inspection lid 17 without preparing a ladder or stepladder. This can be done extremely easily from a low position by simply removing the holder, making it easier to maintain.

[Operation and Effect] Since the present invention is constructed as described above, a storage rack is provided on the ceiling in order to effectively utilize dead space, but the storage rack can be raised and lowered freely. When it is suspended and in the lowered position, the front door opens and closes automatically. Therefore, you can easily and safely take things in and out from a low position without requiring a ladder or stepladder or having to do heavy labor such as climbing up and down a ladder or stepladder while holding things. As a result, workability and safety in the ceiling storage can be significantly improved.

Moreover, the opening/closing door of the storage rack is opened and closed based on the storage rack moving up and down within a predetermined range that exceeds the extension limit position of the elevation guide member, so by adjusting the extension limit position of the elevation guide member, the storage rack The lowering limit position can be set freely, and as a result, you can always put things in and take them out at the optimal position without being affected by the ceiling height. It can be made highly versatile.
