Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to two vertically arranged cells.
The present invention relates to an elevating and accommodating device in which the upper and lower positions of the two accommodating portions can be changed by raising and lowering the accommodating portions as needed.

[0002]

2. Description of the Related Art Hanging cabinets have been used to make effective use of high spaces, which tend to become dead spaces.
However, since the storage is high, it is not possible to freely take things in and out without using a step or the like. Recently, we support the storage units installed in high places such as hanging cabinets so that they can be raised and lowered.
A lifting / lowering storage device has been proposed and put into practical use, in which items are put in and taken out at a lower position and stored at an upper position. That is, as shown in FIG. 16, the storage unit 101 is supported by the support arm 102 configured as a parallel link, and the storage cabinet 1
It is the one that was made to be an interior for 03. Reference numeral 104 in the drawing denotes a workbench such as a kitchen device.

As a reference, Japanese Unexamined Patent Publication No. 7-148029
Japanese Patent Laid-Open No. 7-148031 and others.

However, in such an up-and-down storage device, there is a problem in that the cabinet 103 cannot be placed at a too high position because the height distance to be moved up and down is small.

Further, when the weight of the storage portion 101 increases due to the stored items, it is necessary to apply a large force to the operation for raising the storage portion 101, which is difficult for a weak woman or child to use.

FIG. 16 shows such an elevator storage device.
When installed on the upper part of the work table such as kitchen equipment like
Since the front side of the cabinet 103 of the storage unit 101 is in the lowered position, there is a problem that work cannot be performed on the work table 104 such as a sink when the storage unit 101 is lowered.

Therefore, the present inventor has newly proposed an elevating storage device as shown in the figure. That is, the lifting and lowering storage device shown in the figure arranges the two storage parts provided with the cooperation means for cooperating with each other up and down, and when the upper storage part is lowered by the rotation of about 180 degrees, the lower storage part is driven by the momentum. It is possible to raise and lower parts to switch the vertical position. Specifically, the first storage portion 111 and the second storage portion 112 arranged vertically are provided, and the storage portions are supported by supporting fulcrums 113, 1
A support member 116 that is rotatably supported by 14 to connect the respective storage units and that rotates around a rotation fulcrum 115 set between the support fulcrums 113 and 114, and a rotation fulcrum 115 that is horizontal in a direction perpendicular to its axis. The sliding support part 117 that supports the sliding part 117 so as to be movable in the direction and the roller 118 on the back part of the first storage part 111, and the back plate 119 of the cabinet 119.
The roller 118 is brought into contact with a. Reference numeral 120 is a handle provided in the storage section 112.

This lifting and lowering storage device allows a user to hold a handle 120.
Grip and pull out the storage part 112 to the front,
Support member 1 supporting 2 and being connected to the storage section 111
Since 16 rotates about the rotation fulcrum 115, the storage part 112 moves in the ascending direction and simultaneously moves the storage part 111 in the descending direction. Since the roller 118 provided on the back of the storage section 111 abuts the back plate 119a and does not allow the storage section 111 to project rearward during movement, the support member 116 slides the rotation fulcrum 115 on the sliding support section. It moves to the front through 117, and storage parts 111, 1
The replacement operation is completed while the interference of 12 is minimized.

As described above, the elevating and retracting device according to the present proposal enables a height distance for ascending / descending to be larger than that of the conventional device, and can be installed at a higher position.
Even when the weight of each storage unit increases, the force of the one storage unit to move downward can reduce the force of the other storage unit in the upward direction, making it easy for weak women, children, and the elderly to use. It has become possible to realize an elevator storage device. In addition, since there is no protrusion of the storage portion to the front of the storage box body due to the rotation of 180 degrees, there is an effect that it is possible to work on a work table such as a sink with the storage portion lowered. .

[0010]

However, even with such a lifting / lowering storage device, when the weight difference between the first and second storage portions is large, a large force is applied during the vertical movement of the storage portions. There was a demand for improvement in operability, such as the need for it and a sudden up-and-down movement.

The present invention makes it easy to move up and down,
Moreover, it is an object of the present invention to provide a highly safe lifting / lowering device.

[0012]

In order to solve the above-mentioned problems, an elevator storage device according to the present invention rotates a storage portion around a rotation fulcrum so as to move the storage portion between an upper position and a lower position substantially directly below the storage position. The storage unit elevating device for elevating and lowering is provided with a load adjusting mechanism.

By adjusting the balance of the load of the storage portion by the load adjusting mechanism, the storage portion can be moved up and down with a light operating force.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevating storage device according to claim 1 of the present invention is a storage part for rotating a storage part around a rotation fulcrum to elevate the storage part between an upper position and a lower position substantially directly below the storage part. The lifting device has a configuration in which a load adjusting mechanism is provided, and the load adjusting mechanism adjusts the balance of the load of the storage unit, so that the storage unit can be moved up and down with a light operating force.

According to a second aspect of the present invention, there is provided a lifting / lowering storage device having first and second storage portions, and by moving the second storage portion in conjunction with the movement of the first storage portion. , The first storage part and the second storage part are interchanged, and the load adjusting mechanism adjusts the load balance of the first and second storage parts substantially evenly, so that a light operating force is required. The first and second storage parts can be exchanged. In addition, it prevents a rapid up / down movement and can be used with confidence.

According to a third aspect of the present invention, in the lifting and lowering storage device, each storage part is supported by a predetermined support fulcrum to connect the first storage part and the second storage part, and between the support fulcrums.

It is configured to include a sliding support portion that supports the storage portion as much as possible, and guide means that moves one of the storage portions in a substantially vertical direction.

Then, the rotation fulcrum is horizontally moved in a direction perpendicular to its axis, and at this time, when one of the storage units is guided in a substantially vertical direction, the other storage unit rotates while horizontally moving and temporarily moves to the outside of the cabinet. After moving and returning to the inside of the cabinet again, the first and second storage parts can be inverted in the vertical arrangement at that position. With such an operation, the cabinet for accommodating each accommodating portion can be made extremely compact, so that the installability of the elevating and accommodating device becomes good.

According to the fifth aspect of the present invention, since the load adjusting mechanism is constructed by using the weight and only the weight is added, the lifting and lowering storage device can be provided at a relatively low cost.

According to a sixth aspect of the present invention, in the lifting and lowering storage device, the load adjusting mechanism includes a moving means for moving the weight between the support fulcrum side of the first storage part and the support fulcrum side of the second storage part. Since the structure is provided and the weight is simply moved between the first and second storage portions, the structure can be extremely simple.

According to a seventh aspect of the present invention, there is provided an elevating / storing device in which the weight moving operation parts are arranged at both the supporting fulcrum side of the first accommodating part and the supporting fulcrum side of the second accommodating part. When installing the lifting and lowering storage device at a high place such as under the ceiling, the weight can be moved at a position where the lower storage section can be easily reached, and when installing at a low place such as on the floor, the weight can be moved.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIGS. 1 to 7 show Embodiment 1 of the present invention.

First, the elevating mechanism used in the first embodiment will be described with reference to FIGS. FIG. 1 is a side sectional view of a lifting / lowering storage device according to a first embodiment of the present invention. FIG. 2 is a sectional view of the main part of the front of the lifting / lowering device in the same embodiment. FIG. 3 is a perspective view of the lifting and lowering storage device in the same embodiment except for the cabinet. FIG. 4 is a sectional view of an essential part of one of the lifting mechanisms as seen from the front. FIG. 5 (a)-
(G) is a side sectional view for explaining a replacement operation sequence of the lifting / lowering storage device in the embodiment.

As shown in FIG. 1, the lifting mechanism 1 includes a support fulcrum P1 of the first storage section 2 and a support fulcrum P of the second storage section 3.
A support arm 4 serving as a support member for connecting between the two and the storage portions 2 and 3 is attached to both side plates of a cabinet 5 which accommodates the storage portions 2 and 3 in its upper and lower positions and has a front face opened, and the rotation fulcrum O of the support arm 4 is attached. And a first posture regulating means 7a for keeping the first storage part 2 in a constant horizontal posture regardless of the rotation angle.
And a second posture regulating means 7b for maintaining the horizontal posture of the second storage portion 3 and a guide means 8 for regulating the moving path of the second accommodating portion 3 when moving up and down. The guide 9a constituting the guide means 8 is attached to the back surface of the cabinet 5, and the guide 9a receives the guide rollers 9b provided above and below the back of the second storage unit 3 to prevent the front and rear movement thereof, and to store the guide roller 9b. Guide the part 3 so that it only moves vertically.

As shown in FIG. 2, the elevating mechanism 1 described above is provided as elevating mechanisms 1L and 1R at symmetrical positions, and the rotation fulcrums O of the supporting arms 4L and 4R are connected by a connecting shaft 10 to form left and right sides. The elevating mechanisms 1L and 1R are configured to operate in synchronization. As a result, the first and second storage units 2 and 3 are integrally supported on the left and right, and even if the load is unbalanced due to the bias of the stored items, the left and right movements do not occur. The difference between the two is eliminated.

The lift mechanism 1L shown in FIG. 4 will be further described as an example. The support arm 4L is connected by a connecting shaft 10 at an intermediate portion corresponding to the rotation fulcrum O thereof and is rotated to the inner surface 12 of the side plate of the cabinet by a horizontal moving shaft 11L. Movably supported,
The horizontal movement shaft 11L has rollers 13a, 1 arranged above and below it.
3b is inserted into the recesses formed in a U-shaped cross section above and below the sliding support portion 6L so that the sliding support portion 6L can be smoothly moved in the horizontal direction. A fixed pulley 14L is fixed to the tip of the horizontal moving shaft 11L concentrically with the rotation fulcrum O.

Support fulcrums P1 at both ends of the support arm 4L
A rotary pulley 16L and a rotary wheel 17L are concentrically and rotatably mounted on the shafts 15La and 15Lb fixed to the P2 position, respectively.
However, the second storage portion 3 is fixedly supported by the rotating wheel 17L at substantially central portions of the side plates 2L and 3L. The fixed pulley 14L and the rotary pulley 16L are set to have the same diameter dimension, and the timing belt 18 is stretched between them.
It constitutes the first attitude regulating means 7a.

Here, the storage units 2 and 3 by the lifting mechanism 1
The ascending / descending operation of will be described with reference to FIGS.

As shown in FIG. 5A, the cabinet 5
When the upper and lower positions of the first storage section 2 and the second storage section 3 stored in the above are switched, the operation handle A of the first storage section 2 having no guide roller 9b is pulled out to the front. Then, since the support fulcrum P1 of the first storage part 2 is rotated forward about the rotation fulcrum O of the support arm 4, the second storage part 3 tries to rotate the support fulcrum P2 backward. The second storage portion 3 side guides the guide roller 9b.
Since a vertical guide is received by being pressed and received a, the rotation fulcrum O of the support arm 4 is pushed horizontally in the sliding support portion 6 by the rotating motion of the support arm 4,
As shown in FIGS. 5 (b) to 5 (d), the second storage portion 3 is the first
It rises in the vertical direction with the rotation of the storage unit 2.

When the first storage section 2 is further rotated from the state shown in FIG. 5D, the rotation fulcrum O of the support arm 4 is pulled in the direction of returning to the original position, contrary to the above. As shown in (e) to (f), the first storage part 2 rotates and enters the lower part of the cabinet 5, and the second storage part 3 moves vertically. When it further rises and the first storage portion 2 enters the lower position where the second storage portion 3 was originally arranged as shown in FIG. 5 (g), the second storage portion 3 moves to the first storage position. The storage units 2 are moved to the upper position where they were originally arranged, and the arrangement positions of the first storage unit 2 and the second storage unit 3 are switched up and down.

When the first storage portion 2 is pulled out from the state shown in FIG. 5 (g) and rotated in the opposite direction to the above operation, the second storage portion 2
The storage part 3 of FIG. 5 descends in the vertical direction, and (f) to (a) of FIG.
The reverse operation of can restore the original array position.

In the above-mentioned vertical replacement operation of the storage parts 2 and 3, since the first storage part 2 is supported by the support arm 4 on the support fulcrum P1 so as to be rotatable about one axis.
Due to the displacement of the center of gravity of the first storage unit 2 with respect to the support fulcrum P1 and the rotation operation of the first storage unit 2, the horizontal posture tends to tilt. Here, the rotary pulley 16 fixedly supported by the first storage unit 2 has a timing belt 18 stretched between the rotary pulley 16 and the fixed pulley 14 located at the rotation fulcrum O, and the rotary pulley 16 is rotationally interlocked in a slip-free manner. Now, the rotary pulley 16 and the fixed pulley 14 are set to have the same diameter, and the timing belt 18 has the same angle in the direction opposite to the direction in which the support angle of the support arm 4 changes due to the rotation of the first storage section 2. Only the first storage part 2 is rotated, and as a result, the first storage part 2 can always maintain its horizontal posture.

Next, a structure in which a load adjusting mechanism 19 is added to the above-described lifting mechanism will be described with reference to FIGS. 6 and 7.

FIG. 6 is a side sectional view of the lifting / lowering storage device in this embodiment. FIG. 7 is a side sectional view for explaining the replacement operation sequence in the embodiment. The load adjusting mechanism 19 is composed of a weight 22 which is a balance adjusting body and moving means 23a and 23b for moving the weight to balance the weight.
The structure of the support arm 4 will be described below. The support arm 4 is integrally formed with a casing 27 that houses the support arm 4. Both ends of the casing 27 are locking portions that rotatably hold the lead screw 20. 21a and 21b are provided, and bevel gears 24a and 24b are provided at both ends of the lead screw 20, respectively.
And bevel gears 25a, 25b at right angles to them.
And bevel gears 25a and 25b are fixed to rotary operation shafts 26a and 26b, respectively. A hexagonal head B serving as a weight moving operation portion is formed at the tips of the rotation operation shafts 26a and 26b, and the weight 22 is moved in parallel with the support arm 4 by rotating operation using a box driver or the like. I am able to do it. Here, the weight 22 is formed with a threaded portion 22s,
The bevel gear 2 is attached so as to mesh with the lead screw 20, and by rotating the rotary operation shaft 26a or 26b.
It is possible to transmit the weights 5a and 25b to the bevel gears 24a and 24b, rotate the lead screw 20, and slide the weight 22 in parallel with the support arm 4. Also lead screw 2
If the screw inclination of 0 is made gentle, the weight 22 is stopped and fixed at an arbitrary position and does not move during the lifting operation.

Here, for example, when the weight of the first storage portion 2 side becomes excessively heavier than that of the second storage portion 3 side, the weight 22 is slid toward the support fulcrum P2 of the second storage portion 3. It suffices to move the fulcrum on both sides of the rotation fulcrum O, and the lifting operation force can be reduced. Naturally, the balance operation can be performed in the same manner even when the weight settings of the storage units 2 and 3 are opposite to the above.

A space in which the lead screw 20 and the weight 22 slide is stored in a casing 27 which is integrated with the support arm 4, and a peep window 28 is provided at an important portion such as an end portion or a central portion of the casing 27. Has been formed. As a result, the movement space of the weight 22 is covered and made clean, and the role of a protective cover that prevents the weight 22 attached to the support arm 4 that rotates when the storage units 2 and 3 are moved up and down from directly contacting the user. Can be fulfilled. Also,
Since the viewing window 28 is provided at a key portion, it is possible to easily confirm at which position the weight 22 is held, and the balance can be easily adjusted.

Further, the moving means 23a and 23b provided at both ends of the support arm 4 can adjust the balance at any of the upper and lower positions, and the cabinet 5 can be moved to the halfway position (c) of the cabinet 5 as well. The balance can be adjusted from the front.

(Embodiment 2) FIG. 8 is a side sectional view showing an elevating / lowering device according to Embodiment 2 of the present invention. The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted. Particularly, the lifting mechanism is the same as that of the first embodiment.

The second embodiment is different from the first embodiment in the load adjusting mechanism, and the weight 22 does not slide on the support arm 4 but rotates. That is, the weight 22 is supported by the tip of a weight support rod 28 that rotates about an axis D provided in the vicinity of the rotation fulcrum O on the support arm 4 as a fulcrum.
The support arm 4 can be moved to either the support fulcrum P1 side or the support fulcrum P2 side, and can be fixed by the catch 29 at this position. According to this, the moving mechanism of the weight becomes extremely simple, and the moving operation is performed by the weight 22.
Can be very fast, just flipping. By equipping the left and right support arms 4L and 4R with the moving mechanism of the weight 22 and arranging the weights 22 on the left and right in different directions, the weights can be equally distributed to the support fulcrums P1 and P2. .

(Embodiment 3) FIG. 9 is a side sectional view showing an elevating / lowering device according to Embodiment 3 of the present invention. The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted. Particularly, the lifting mechanism is the same as that of the first embodiment.

The third embodiment is different from the first embodiment in the load adjusting mechanism. The weight 22 does not slide on the support arm 4, but the first storage section 2 and the second storage section 3 are different from each other. It moves between.

Now, plate-shaped magnets 30a and 30b are attached to the bottom surface of the first storage section 2 located above and the ceiling surface of the second storage section 3 located below, respectively. A weight 22 made of iron is attracted to the magnet 30b on the side of the storage portion 3. Here, when the weight 22 is moved backward, the weight 22 separates from the magnet 30b and is attracted and moved to the magnet 30a on the first storage unit 2 side. If the weight 22 attracted to the magnet 30a is moved forward, the weight 22 can be returned to its original position in the same manner.

According to this, since the weight 22 can be adjusted in weight balance between the storage units 2 and 3 by making the vertical movement of the weight 22 the shortest distance, the moving mechanism of the weight 22 becomes extremely simple, and The moving operation can also be extremely labor-saving.

The same can be said even if the weight 22 is transferred between the bottom surface of the second storage portion 3 located above and the ceiling surface of the first storage portion 2 located below.

In FIG. 9, only one weight 22 is attached. However, if the weight 22 is made smaller and a plurality of weights are provided, fine weight adjustment can be performed.

(Embodiment 4) FIG. 10 is a sectional view showing an elevating and retracting device according to Embodiment 4 of the present invention. The same reference numerals as those in the first and third embodiments have the same structure, and the description thereof will be omitted. Particularly, the lifting mechanism is the same as that of the first embodiment.

The fourth embodiment is different from the third embodiment in the load adjusting mechanism, and includes the inner bottom surface of the cabinet 5 for accommodating the first and second accommodating portions 2 and 3 in the vertical arrangement position, and the first and second accommodating portions. Alternatively, the magnets 30a, 30b, and 30c are provided at positions where the second storage units 2 and 3 are arranged below, and the weight 22 moves between them, that is, between the storage unit bottom surfaces. According to this, the vertical movement distance of the weight 22 is small, and the moving operation can be easily performed by the simple weight moving mechanism.

In FIG. 10, the weight 22 is moved between the inner bottom surface of the cabinet 5 and the bottom of the storage section at the lower position, but the inner top surface of the cabinet 5 and the storage section at the upper position. It may be face to face. Further, it is the same that the weight 22 can be finely adjusted by providing a plurality of weights 22.

(Embodiment 5) FIG. 11 is a sectional view showing an elevating and retracting device according to Embodiment 5 of the present invention. The same reference numerals as those in the first and third embodiments have the same structure, and the description thereof will be omitted. Particularly, the lifting mechanism is the same as that of the first embodiment.

The fifth embodiment is different from the third embodiment in the moving direction of the load adjusting mechanism and the weight. The weight 22 is mounted on the ceiling surface of the first storage section 2, and the slide rail 31 is provided.
This allows it to move horizontally in the front-rear direction and be fixed. Here, if the weight 22 is moved and fixed forward, the center of gravity of the first storage portion 2 side becomes far from the rotation fulcrum O, the rotational moment to descend and increase increases, and conversely if the weight 22 is moved and fixed backward. The rotational moment is reduced.

As described above, the weight balance between the storage units 2 and 3 can be adjusted by horizontally moving the weight 22 back and forth. In particular, since the weight 22 can be moved in the horizontal direction and does not need to be moved in the vertical direction, the force required for the moving operation is extremely small and the adjustment work can be performed easily.

If necessary, it is possible to equip the second storage section 3 with the same balance adjusting means as described above.

(Sixth Embodiment) Next, a sixth embodiment of the present invention which is different from the above-described first to fifth embodiments in the lifting mechanism will be described with reference to FIGS. The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

It is also installed in the storage part 3 of the
This is the point that the second posture regulating means 7b is constructed by multiplying a.

As for the operation of the above configuration, when the first storage portion 2 or the second storage portion 3 is rotated so as to be pulled out in the front or rear direction, the other storage portion connected by the support arm 4 is also rotated. Then, as shown in FIGS. 13 (a) to 13 (c), each of the storage units is rotated by 180 degrees, and the first storage unit 2
And the upper and lower positions of the second storage portion 3 are interchanged.

In the above construction, if the lower position is set to a position where it is easy to put in and take out stored items, the upper and lower positions of stored items which are difficult to put in and take out can be swung up and down to change the upper and lower positions. The point that it can be effectively used is the same as that of the above-described first to fifth embodiments, but this structure has an effect that the structure can be simplified because a sliding support portion is not required. In addition, each storage unit 2, 3
By providing the inlets and outlets on both sides, it is possible to take in and out from both the front surface and the rear surface, and further, since it can be freely rotated in a desired rotation direction, there is an advantage that the upper and lower exchange operation becomes easy. Further, when the load adjusting mechanism is adopted for the lifting mechanism, the weight moving operation part 23a provided at both ends of the support arm 4,
Since 23b can be operated at any position,
You can adjust the balance from up and down, front and back, anywhere,
It is even more convenient.

Although not shown, even if the balance adjusting means of each of the above-described Embodiments 2 to 5 is adopted in the lifting mechanism, the lifting and lowering operation device which is easy to perform the lifting and lowering operation and has high safety is provided. That is, the object of the present invention can be achieved.

(Embodiment 7) Next, an embodiment 7 of the present invention will be described which is different from the above embodiments 1 to 6 in the lifting mechanism.

First, the lifting mechanism used in the seventh embodiment will be described with reference to FIGS. 14 and 15.

The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted. Particularly, the load adjusting mechanism is the same as that of the first embodiment.

FIG. 14 is a side sectional view of the lifting / lowering device in this embodiment. Also, FIGS. 15 (a) to (c)
FIG. 4 is a side sectional view schematically showing the operation sequence of the lifting / lowering storage device in the present embodiment.

In FIG. 14, a first cabinet is provided in the cabinet 5.
The storage part 2 and the second storage part 3 are vertically arranged, and the support fulcrums P1 and P2 are connected and supported by the support arm 4, and the midpoint of the support arm 4 is supported by the cabinet 5.
