Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a storage device that can utilize the space under the ceiling, that is, a storage device such as a shelf, a basket, or other storage means structured according to the purpose, which can be installed horizontally on the ceiling. The present invention relates to a storage device which is stored in a back space and can swing the storage means downward from the horizontal position to the vertical position and further pull it down to an appropriate height when taking out and taking out the stored items.

(Prior Art and its Problems) The storage device described above uses a swinging rail that can swing up and down between a horizontal position and a vertical position, and the storage means is attached to this swinging rail. The storage means, which is supported so as to be movable in the length direction of the swing rail, is pulled down vertically and is in a used state (when taking out and taking out stored items), and is stored in a horizontal position in, for example, an attic space. In order to facilitate the push-up storage operation, a biasing means for urging the swing rail to swing upward, and a storage means for pushing the swing rail against the swing rail are provided. A biasing means is required to bias the support to move toward the fulcrum.

If these two biasing means were provided independently, the number of parts would increase and the cost of the entire product would increase.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention provides a swing rail that can freely swing up and down between a horizontal position and a vertical position. A storage means is supported so as to be movable in the horizontal direction, and an automatic winding-up rotary body for lifting cables, which has one end locked to the storage means, is pivotally supported at an upper position near a fulcrum of the swing rail. At an intermediate position between the rotating body and the swinging rail in a horizontal position, there is a lifting cable guide that is guided by a fixed guide rail and movable in the direction of distance from and near the fulcrum of the swinging rail, and that guides the middle of the lifting cable. A movable body is provided, and the movable body and the swing rail are connected by a push/pull member,
The present invention proposes a storage device configured such that as the swing rail swings from a vertical position to a horizontal position, the movable body moves toward the free end of the swing rail.

(Operation of the Invention) When the storage means is used, the storage means supported by the swinging rail in a horizontal position is pulled down so as to change the swinging rail to a vertical position, and at the same time, the storage means is By pulling down the storage means also with respect to the rail, the storage means can be switched to a vertical position and can be pulled down to a required height. At this time, the movable body for guiding the lifting rope is
The lifting cable, which is stretched by the push-pull member, has reached a position near the fulcrum of the swing rail, and the lifting cable suspending the storage means is in a substantially vertical position.

When the storage means is returned to the horizontal position and raised upward from such a state, the storage means is pushed up against the swing rail in the vertical position. At this time, the winding force of the automatic winding rotary body acts upwardly on the storage means via the lifting rope, so that the storage means can be pushed up lightly. Next, when the storage means is pushed up together with the swing rail to return to the horizontal position, the push-pull member pushes the lifting cable guide movable body away from the swing rail fulcrum as the swing rail swings. Therefore, the direction of the lifting cable suspending the storage means changes from the vertical position to the diagonal direction suitable for lifting the swing rail (storage means) upward, and the winding force of the automatic winding rotor increases. acts to raise the swing rail (storage means) to a horizontal position via the lifting cable. Therefore, once the swing rail (storage means) is pushed diagonally upward to a certain extent, the swing rail (storage means) will be brought to a horizontal position by the winding force of the automatic winding rotor. It can be configured so that it can be lifted up.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

Reference numeral 1 denotes a storage box type storage means, in which a pair of left and right swing rails 2 are provided with support rollers 3a, 3b.
It is supported so as to be movable in the length direction of the swing rail 2 via the swing rail 2. Reference numeral 4 denotes an outer storage box installed in the attic space so that the lower open part is flush with the ceiling surface, and one end of the swing rail 2 is arranged concentrically with the left and right side walls 5 of the storage case. It is pivotably mounted on a horizontal support shaft 6 so as to be vertically swingable. Reference numeral 7 denotes a rotary body for automatically winding up the lifting rope 8, which is biased in the direction of winding up the lifting rope 8 by a built-in spring spring, and is attached to the left and right side walls 5 of the outer storage box 4 so as to rotate the lifting rope 8. It is pivotally supported at a position near and above the rail support shaft 6. The free end of the lifting cable 8 passes between a pair of guiding sheaves 10 provided on the movable body 9 for guiding the lifting cable, and is connected to the side where the swing rail support shaft 6 is located on both the left and right sides of the storage means 1. It is locked at a position near the opposite end via a rotatable locking tool 11.

The pair of left and right lifting cable guide movable bodies 9 are
Each of them is movably supported by a fixed guide rail 12 via a roller 13, and the fixed guide rail 12 is oscillated at an intermediate position between the oscillating rail 2 in a horizontal position and the automatic winding rotary body 7. It is fixed to the left and right side walls 5 of the storage outer case 4 with the end opposite to the side on which the moving rail support shaft 6 is located slightly inclined so that it is positioned upward. The pair of left and right lifting cable guide movable bodies 9 and the pair of left and right swing rails 2 located on the same side are interlocked and connected by push/pull members (links or rods) 14, respectively.

As shown in FIG. 1, when the storage means 1 is in a horizontal position together with the swing rail 2 and is stored in the outer storage case 4, the push-pull member 14 lifts the cable guide movable body 9. Fix the guide rail 1
The locking tool 11 is pushed to the far side end with respect to the swing rail support shaft 6 of the second swing rail, and the locking tool 11 is located at a position substantially directly below the movable body 9 at this time. Further, as shown in FIG. 4, when the storage means 1 is in a vertical position together with the swing rail 2, the lifting cable guide movable body 9 is moved by the push/pull member 14 to support the swing rail of the fixed guide rail 12. It is pulled toward the end near the shaft 6, so that the lifting cable 8 between the guide sheave 10 of the movable body 9 and the locking tool 11 is in a vertical position substantially parallel to the swing rail 2. It is composed of

Although not shown, the storage means 1 has a swing rail support shaft 6 of the bottom plate 15 that is parallel to or flush with the ceiling surface when the storage means 1 is in the horizontal storage position shown in FIG. An operating handle is provided near the opposite end. This operating handle is preferably connected to the bottom plate 15 when not in use.
When a type that can be stored without protruding from the storage case is used, and an automatic locking means for locking the storage means 1 to the storage case 4 in the horizontal storage position is used, this locking means must be unlocked. It is desirable that the operating handle also serves as a lever.

In the storage device configured as described above, the automatic winding rotor acting on the lifting cable 8 moves the storage means 1 from the horizontal storage position as shown in FIG. 7 winding force,
That is, when pulled down against the lifting force, the storage means 1 swings downward together with the swing rail 2 around the support shaft 6. When the storage means 1 is pulled down from the horizontal storage position to the vertical position in this way, the push/pull member 14
moves the lifting cable guiding movable body 9 to the swinging rail support shaft 6
As the movable body 9 is pulled toward the side, the direction of the lifting cable 8, one end of which is locked to the storage means 1 via the guide sheave 10 of the movable body 9, changes to the swing rail 2 as the storage means 1 swings downward. The rotational force that causes the storage means 1 to swing upward around the swing rail support shaft 6 gradually decreases. Therefore, even if the lifting force acting on the lifting cable 8 is made sufficiently large so as to reliably hold the storage means 1 in the maximum loaded state with a specified weight of stored items stored in the storage means 1 in the horizontal storage position, As the storage means 1 approaches the vertical position, the storage means 1 can be swung to the vertical position with a smaller force.

As shown in FIG. 4, when the storage means 1 and the swing rail 2 are in a completely vertical position, the lifting cable 8 is also vertically oriented, and the upward swing rotational force acting on the storage means 1 is almost zero. becomes. In this state, the storage means 1 can be pulled vertically downward relative to the swing rail 2 against the lifting force acting on the lifting cable 8. The lifting force acting on the lifting cable 8 when in this vertical position is determined by whether the storage means 1 in the maximum load state can be pulled down with a slight pulling force as described above, or when the storage means 1 is moved at a slow speed. It can be set to a level that allows for natural descent.

When the storage means 1 is lowered to the vertical lower limit position as shown by the imaginary line in FIG. 4, the storage means 1
However, if a locking means that automatically locks the storage means 1 to the swing rail 2 at the vertical lower limit position is also used, the storage means 1 can be safely and easily moved vertically. Since it can be held at the lower limit position, even if the lifting force acting on the lifting cable 8 is increased, it is possible to safely take in and take out the stored items.

The work of returning storage means 1 to its original horizontal storage position is as follows:
It is sufficient to perform the procedure in the reverse order of the work of lowering the device to the vertical usage position described above. At this time, when the storage means 1 is raised to the upper movement limit position with respect to the swing rail 2, the rotational force that causes the storage means 1 to swing upward together with the swing rail 2 is almost zero. The means 1 must be swung upwards about the swiveling rail support shaft 6. Along with this upward swinging, the push-pull member 14 pushes the lifting cable guide movable body 9 away from the swinging rail support shaft 6, so the direction of the lifting cable 8 swings upward on the swinging rail 2. As the angle between the storage means 1 and
automatically swings back to the horizontal storage position.

Although a storage box-type storage means 1 is illustrated as an example, the storage means 1 is not limited thereto. For example, it is possible to use a structure that suits the purpose, such as a basket type or a structure equipped with a swing type support that automatically maintains a horizontal position regardless of the attitude of the storage means. Of course, the present invention is not limited to a storage means for storing stored items in and out. For example, it may be a device that permanently stores audio equipment such as a television or stereo (in this case, the casing of the audio equipment serves as the storage means).

(Effects of the Invention) As described above, according to the storage device of the present invention, the urging means for pulling up the storage means with respect to the vertically swinging rail and the urging means for swinging the vertically swinging rail upward. and by one lifting cable automatic winding rotor (in the example, a pair of left and right lifting cable automatic winding rotors are used to double the lifting force and to lift the storage means in a balanced manner on the left and right sides). It can be used for both purposes. Therefore, compared to the case where dedicated biasing means are provided, the number of parts is reduced and implementation can be made at low cost. Moreover, when the storage means is swung to a vertical position together with the swing rail, the lifting cable is oriented vertically or close to this, and almost no upward swing rotational force is applied to the storage means. The work of vertically lowering the storage means with respect to the swinging rail in the vertical position can be easily carried out without using a means for locking the swinging rail in the vertical position.

In addition, since a movable body for guiding the lifting cable is also used, even if the lifting cable automatic winding rotary body is disposed directly above the swing rail fulcrum and the overall structure is made low-volume, the details will be explained in the examples. As described above, the direction of the lifting cable can be automatically changed depending on the situation, and the lifting force acting on the lifting cable can be efficiently utilized for swinging the storage means to the horizontal storage position. Therefore, even a device with a relatively small winding force can be effectively used as a rotating body for automatically winding up a lifting cable.
