The present invention relates to an electrically operated elevating shelf for securing storage space by utilizing a high space near the ceiling.

[Background technology]

Conventionally, the lifting shelf body is housed in a shelf casing part that is open at the bottom so that it can be raised and lowered, and an electric lifting mechanism for raising and lowering the lifting shelf body is provided in the shelf casing part, and a wire hanging from the electric lifting mechanism is connected to the lifting shelf main body. It is hooked onto a movable pulley attached to the top surface, and the elevating shelf body can be raised and lowered by an electric lifting mechanism. There is an elevating shelf in which a switch is provided on the elevating shelf main body so that the elevating and lowering operations can be performed from a low position. However, in such an elevating shelf, it is not possible to provide a door on the front surface of the shelf casing. In other words, if a door is provided on the front side of the shelf casing, when the door is opened while the elevating shelf body is being lowered, the internal movable pulley and wires will be exposed, which not only looks bad but is also dangerous. Since a door cannot be provided, it is not possible to take in and take out the stored items in the elevating shelf when the elevating shelf is raised, and it is not possible to take in and take out stored items unless the elevating shelf is lowered , it was inconvenient.

[Purpose of invention]

The present invention was developed in view of the above-mentioned technical background, and its purpose is to enable quick loading and unloading of stored items even when the elevating shelf body is stored within the shelf casing. It is in.

[Disclosure of invention]

In the present invention, an elevating shelf main body 2 is housed in a shelf casing part 1 that is open at the bottom so that it can be raised and lowered, a door 7 is provided at the front opening of the shelf casing part 1, and the elevating shelf main body 2 is moved up and down inside the shelf casing part 1. A wire 10 hanging from the electric lifting mechanism is hooked to a movable pulley 9 attached to the top surface of the lifting shelf main body 2, and the electric lifting mechanism, wire 10, and movable pulley 9 are connected to the shelf. This is characterized in that a telescopic bellows cover 32 for hiding from the front opening of the casing part 1 is provided between the top surface of the shelf casing part 1 and the top surface of the elevating shelf body 2. Since the front surface of the shelf casing part 1 is opened and the door 7 is provided there, even when the elevating shelf main body 2 is stored in the shelf casing part 1, opening the door 7 allows the elevating shelf main body 2 to open. By exposing the storage area, you can directly take in and take out stored items. Moreover, since the bellows cover 32 is provided between the upper surface of the elevating shelf body 2 and the top surface of the shelf casing, even if the door 7 is opened while the elevating shelf main body 2 is lowered, the electric elevating mechanism 3 The wire 10 and movable pulley 9 are not exposed, which not only maintains a good appearance, but also prevents accidents such as hands being caught when touching these internal mechanisms, resulting in high safety. It is something. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The shelf casing part 1 is constructed by hinged edges of a pair of openable/closeable doors 7 to the front surface of a box body 8 whose front and bottom surfaces are open. An electric lifting mechanism 3 is installed approximately at the center of the top surface of the shelf casing portion 1 .
On the other hand, a movable pulley 9 that can freely roll is attached to the upper surface of the elevating shelf main body 2. Therefore, the shelf casing part 1 can accommodate a lifting shelf main body 2, and the lifting shelf main body 2 has a movable pulley 9 suspended from a wire 10 hanging from an electric lifting mechanism 3. The elevating shelf main body 2 can be raised and lowered from the lower opening of the casing part 1. The electric lifting mechanism 3 has a structure as shown in FIGS. 6 and 7. That is, a pulley mounting plate 12 attached to one side of the housing 11 has an elongated hole 13 that is long in the vertical direction, and a buffer that can slide vertically along the elongated hole 13 is provided in the elongated hole 13. A shaft 14 is inserted, and the buffer shaft 14 is elastically pulled upward by a spring 15. Further, the pulley mounting plate 12 has a diagonally long oblique hole 16 bored in the diagonal direction, and the shaft 18 of the slack removing pulley 17 is slidably held by this oblique long hole 16. 18 is elastically pulled diagonally upward by a spring 19. In addition, on the other side inside the housing 11, a take-up pulley 23 is connected to the output shaft 22 of the deceleration mechanism 21 connected to the motor 20.
is installed. However, two wires 1
0 is fixed at one end to the buffer shaft 14, and the wire 10 is suspended downward, wound around a movable pulley 9 attached to the upper surface of the elevating shelf main body 2, and then returned to the housing 11. It is wound around a slack take-up pulley 17, and the other end is wound around a take-up pulley 13, respectively. However, motor 1
By driving the wire 10 and winding the wire 10 around the take-up pulley 13, the elevating shelf main body 2 can be raised via the movable pulley 9.
Conversely, by unwinding the wire 10 from the take-up pulley 13, the elevating shelf main body 2 can be lowered. Since the two wires 10 are used in parallel, even if one of the wires 10 is cut, the remaining wire 10 will support the lifting shelf body 2, resulting in the accident of the lifting shelf body 2 falling. There is no risk of causing this.
Further, one end of the wire 10 is fixed to a buffer shaft 14 that is urged upward by a spring 15, so when a downward impact is applied to the wire 10, the buffer shaft 14 moves downward against the elastic force of the spring 15. As a result, the impact applied to the wire 10 is buffered and the wire 10 is prevented from being cut. For example, it is effective in protecting against impact when the motor 11 is started or stopped, or against impact applied to the other wire 10 when one wire 10 is cut. In addition, the slack removing pulley 17 also has a spring 19.
Since the wire 10 is biased obliquely upward, the wire 10 is prevented from becoming slack. The lifting and lowering of the lifting shelf main body 2 is carried out by a switch 4 provided at the front lower part of the shelf casing part 1. By pressing this switch 4, the motor 11 is rotated and the lifting shelf main body 2 is moved up and down. It is designed to be raised and lowered. In addition, the elevating shelf body 2
When the lifting shelf body 2 rises to the upper limit and when the lifting shelf main body 2 descends to the lower limit, limit switches detect this and stop the motor 11, respectively. The elevating shelf main body 2 has a box shape with an open front, and the inside thereof is a storage space. In addition, a movable pulley 9 with two grooves is rotatably attached to the center of the upper surface of the top plate of the elevating shelf main body 2, and as shown in FIG. Two wires 10 hanging down in a shape are hung around a movable pulley 9, and the elevating shelf main body 2 is suspended by the wires 10 and the movable pulley 9. In addition, as shown in FIG. 1, slide rails 24 that are long in the vertical direction are provided on both sides and both sides of the rear surface of the elevating shelf body 2, and a support rail 25 is fixed at the same position in the shelf casing part 1. The four slide rails 29 and the support rails 25 are slidably engaged with each other so that the elevating shelf main body 2 is guided so as to move up and down smoothly. The lifting and lowering of the lifting shelf main body 2 is operated by a switch 4 attached to the lower surface of the lifting shelf main body 2, and this switch 4 and the electric lifting mechanism 3
A cord 6 connects the motor 20 or the electronic control section. A flexible arm 5 is provided between the upper surface of the elevating shelf body 2 and the top surface of the shelf casing portion 1, and the cord 6 is wired along the flexible arm 5. The bending/extending arm 5 has two bars 26 whose ends are rotatably connected to each other by a hinge connecting part 27, and one end of the bending/extending arm 5 is rotatably connected to the top surface of the shelf casing part 1 by a hinge fixing part 28. The other end is rotatably fixed to the upper surface of the elevating shelf main body 2 by a hinge fixing part 29.
Therefore, when the lifting shelf main body 2 goes up and down, the bending arm 5
is bent and extended from the hinge connecting portion 27 in a bifold shape. This bending/extending arm 5 is provided with an annular guide portion 30, and the cord 6 is routed along the bending/extending arm 5 by passing through this guide portion 30. The cord 6 is connected to the switch 4 through the
It is hidden by a cover 31. Therefore, when the elevating shelf main body 2 moves up and down, the cord 6 is folded so as to wrap around the bending/extending arm 5, so that it does not become loose and get caught in the movable pulley 9 or the like. Furthermore, the top surface of the shelf casing part 1 and the elevating shelf body 2
The space between the top surface and the top surface is covered by a bellows cover 32 which is U-shaped in plan view. Bellows cover 32
The bellows cover 32 expands and contracts vertically in a bellows shape, and the upper end of the bellows cover 32 is fixed to the top surface of the shelf casing part 1, and the lower end is fixed to the upper surface of the elevating shelf main body 2. When the shelf body 2 is raised and lowered, the bellows cover 32 expands and contracts as shown in FIGS. 3 and 4, and does not interfere with the raising and lowering of the lifting shelf main body 2. As shown in FIGS. 1 and 3, the front and both sides of the inside of the shelf casing 1 are covered by a bellows cover 32, and the movable pulley 9 and the like are hidden behind the bellows cover 32. Therefore, even when the door 7 is opened as shown in Fig. 1, only the bellows cover 32 is visible, and the internal mechanism is not visible, giving a good appearance and preventing injury from touching the internal mechanism. It is. Therefore, by raising the elevating shelf main body 2 and storing it in the shelf casing part 1, the stored items cannot be seen, and by lowering the elevating shelf main body 2, the stored items can be easily taken in and out. Furthermore, while the elevating shelf main body 2 is rising, the door 7 can be opened to allow storage items to be taken in and taken out. Note that this elevating shelf is not only for simply storing articles, but also includes an electrically elevating type elevating shelf used in the kitchen to store dishes and the like after washing.

[Effect of the idea]

As described above, in this invention, the front side of the shelf casing part is opened and a door is provided there, so even when the elevating shelf body is stored inside the shelf casing part,
By opening the door, the main body of the elevating shelf is exposed, and stored items can be taken in and out directly. Moreover, since a bellows cover is provided between the top surface of the elevating shelf body and the top surface of the shelf casing, even if the door is opened with the elevating shelf body lowered, the electric elevating mechanism, wires, and movable pulley will not be removed. Not only are the internal mechanisms kept in good condition without being exposed, but accidents such as getting your hand caught when touching these internal mechanisms can be prevented, resulting in high safety.
