Reference numeral 19 denotes an interlocking connecting shaft for connecting the bases of the first rotating arms 14 facing left and right. The interlocking connecting shaft 19 is configured so that both the first rotating arms 14 rotate together.
[0022]
A storage rack 20 is usually stored in the storage cabinet 11, and includes a first storage portion 23 by a main body 21 and rack side plates 22 on both sides connected to the main body 21, and a space 24 above the lifting support unit 16 during storage. The first and second rotary arms 14 and 15 are bent to provide a second storage portion 25 that is wider than the first storage portion 23 and at least two storage portions. The main body 21 is configured in a planar shape from the front surface to the back surface of the bottom surface 26 of the first storage unit 23.
[0023]
27 is a shelf member made of a wire rod provided in the storage rack 20, and is configured to have the same height as the bottom surface 28 of the second storage portion 25. Further, a lower handle 29 is formed of a pipe or the like between the rack side plates 22, and a horizontal connection member 30 is formed of a pipe bent in a U shape that regulates the storage height of the second storage portion 25. The upper ends of the main body 21 and the rack side plate 22 are defined as the uppermost portion 31 of the storage rack 20.
[0024]
The distal ends of the first rotary arm 14 and the second rotary arm 15 pivotally supported by the elevating support unit 16 are pivotally supported by the support member 32 and support the rack side plate 22 constituting the wide second storage portion 25. By connecting to the member 32, a parallel link mechanism 33 having four sides is formed, and the storage rack 20 is supported to be movable up and down.
[0025]
Further, the first and second rotating arms 14 and 15 are provided with an inclination correcting means 34 for preventing the storage rack 20 from being inclined. As the inclination correcting means 34, the distance R1 between the pivot points of the first rotating arm 14 is configured to be several mm longer than the distance R2 between the pivot points of the second rotating arm 15. By slightly deforming the parallel link mechanism 33 in this manner, there is a gap at the pivotal support points of the first and second rotating arms 14 and 15 and the front of the storage rack 20 generated by the weight of the storage rack 20 and the stored items. It is intended to prevent inclination to the side.
[0026]
Further, inside the elevating support unit 16, either or both of the buffer means 35 and the urging means 36 that act in conjunction with the rotation of the second rotary arm 15, that is, the elevation of the storage rack 20, are configured. . Note that 37 is an openable / closable door provided in front of the storage cabinet 11, and 38 is a hinge for opening and closing (described only in FIG. 3).
[0027]
In the above configuration, when the storage rack 20 is lowered, if the user pulls down the storage rack 20 with the handle 29, the storage rack 20 is pivoted in the first and second rotations so that the lifting support unit 16 is rotatably supported. The parallel link mechanism 33 and the inclination correction means 34 formed by the arms 14 and 15 always rotate in an arc shape as indicated by the alternate long and short dash line in FIG. At this time, the buffer means 35 and the biasing means 36 act so that the storage rack 20 descends slowly. Further, it can be seen that the bottom surface 26 of the first storage portion 23 does not contact the interlocking connecting shaft 19 and the bottom plate 13 of the storage cabinet 11 as indicated by a two-dot chain line in FIG.
[0028]
Here, in the storage rack 20, the first and second rotary arms 14 and 15 that support the storage rack 20 are bent in a substantially S shape and a substantially L shape instead of being linear, and the first and second rotary arms. Since the support member 32 which pivotally supports 14 and 15 is connected to the second storage portion 25 and the distance between the pivot points (R1, R2) is large, it can be lowered greatly. That is, since the first and second rotating arms 14 and 15 that support the storage rack 20 are bent, the position where they come into contact with the bottom plate 13 of the storage cabinet 11 is considerably lower than that of the linear arm. The rack 20 can be lowered to a position where the uppermost portion 31 is lower than the position of the bottom plate 13 of the storage cabinet 11.
[0029]
In this embodiment, the storage rack 20 is configured by the stopper 17 so that the uppermost portion 31 stops at a height substantially equal to the height of the bottom plate 13 of the storage cabinet 11.
[0030]
Then, after the storage rack 20 is moved up and down after the storage rack 20 is placed in the maximum lowered position, when the storage rack 20 is pushed up again by holding the handle 29, the storage rack 20 has an arc shape as in the lowering. And is stopped and stored at a predetermined position by a stopper 17 in the storage cabinet 11. At this time, the urging means 36 acts so that the operating force when raising the storage rack 20 is reduced.
[0031]
Next, an installation example of the elevating storage device of the present invention will be described.
[0032]
As shown in FIG. 3, the storage cabinet 11 is assumed to be a standard wall cabinet and adopts a height of 700 mm and a depth of 350 mm as outer dimensions. The standard installation height of the storage cabinet 11 is generally around 2300 mm from the floor surface 40 to the top plate 41 of the storage cabinet 11 due to the distance relationship with the floor cabinet 39 installed below the elevating storage device. . The total height (A) of the storage rack 20 and the horizontal connecting member 30 stored in the storage cabinet 11 is about 600 mm.
[0033]
When the height of the uppermost portion 31 of the storage rack 20 and the bottom plate 13 of the storage cabinet 11 are configured to be substantially the same at the maximum lowered position of the storage rack 20, the bottom surface of the first storage portion 23 extends from the bottom plate 13 of the storage cabinet 11. The distance (B) up to 26 is around 450 mm.
[0034]
Accordingly, the distance (C) from the floor surface 40 to the bottom surface 26 of the first storage unit 23 at the maximum lowered position of the storage rack 20 is about 1150 mm. Similarly, the distance (D) from the floor surface 40 to the horizontal connecting member 30 is about 1750 mm. At this time, the height of the bottom surface 28 and the shelf member 27 of the second storage unit 25 is about 1400 mm from the floor surface 40, and is equivalent to about 90% of the lines of adult women (excluding elderly people). It is configured.
[0035]
The height that can be taken in and out is approximately the height of the thumb with both arms raised, and can be the height to the finger joint. For adult women (excluding the elderly), the 10th percentile value obtained by subtracting the fingertip length (third finger length) from the height of the fingertip (upper extremity upper finger tip height) is 1800 mm. In the installation example of the apparatus, about 90% of adult women can reach the uppermost portion 31 of the storage rack 20 and reach the horizontal connecting member 30 and can take in and out the stored items, and the total storage capacity of the storage rack 20 is effective. It can be used for.
[0036]

A storage device can be provided.
[0037]
In addition, since the storage rack 20 includes the first storage portion 23 and the second storage portion 25 wider than the first storage portion 23, the storage capacity of the second storage portion 25 can be increased and storage efficiency can be further increased. Can be provided.
[0038]
Further, by providing the second storage portion 25 in the upper space 24 of the lifting support unit 16, it is possible to avoid contact with the lifting support unit 16 when the storage rack 20 is turned up and down as shown by a two-dot chain line in FIG. In addition, the width dimension of the second storage unit 25 can be maximized, and the space in the storage cabinet 11 can be fully utilized.
[0039]
In addition, since the bottom surface 28 of the second storage portion 25 and the shelf member 27 provided in the storage rack 20 are configured to have the same height, a flat surface is formed between the bottom surface 28 of the second storage portion 25 and the shelf member 27. It is possible to prevent the stored item from tilting or falling.
[0040]
Further, by making the bottom surface 26 of the first storage portion 23 planar from the front surface to the back surface portion, the storage performance of the corner portion is improved and the storage capacity can be expanded.
[0041]
In addition, the first rotary arm 14 is bent to avoid contact with the bottom plate 13 of the storage cabinet 11, and the distal end is bent again in the reverse direction, and the second rotary arm 15 is substantially S. By providing at least two rotating arms 14 and 15 that are bent in an approximately L shape to avoid contact with the U-shaped arm 14, the storage cabinet 20 may come into contact with the storage cabinet 11 when the storage rack 20 is raised or lowered. The rotating racks 14 and 15 do not interfere with each other, and the storage rack 20 can be lowered to a lower position than a simple linear arm.
[0043]
Further, since the tips of the first and second rotating arms 14 and 15 are pivotally supported by the support member 32, the two rotating arms 14 and 15 can be connected at a predetermined position as the lifting support unit 16, and the lifting support is supported. The transportability and workability of the unit 16 can be improved.
[0044]
Further, by connecting the support members 32 of the first and second rotary arms 14 and 15 to the second storage portion 25, the distance between the pivot points (R1 and R2) of the rotary arms 14 and 15 can be increased. A stable ascent and descent can be obtained, and a large arc can be rotated, and the bottom surface 26 of the first storage portion 23 can be easily formed into a planar shape from the front surface to the back surface as described above.
[0045]
Further, by providing the first and second rotating arms 14 and 15 with the inclination correcting means 34 for preventing the inclination of the storage rack 20, it is corrected that the storage rack 20 is inclined due to the weight of the storage rack 20 and the storage items. Thus, it is possible to prevent the stored items from moving and falling, and to give the user a sense of security in terms of appearance.
