Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a storage device used for purposes such as using the inside of a ceiling as a storage area.

[Background technology]

As shown in FIGS. 1 and 2, a ceiling storage device is provided with a rotatable opening/closing lid 4 that covers an opening 8 of a ceiling 7, and a storage box 1 accommodated in the opening 8. Developed by this applicant. In this case, the storage box 1 is the left and right gas springs 3, 3.
It is suspended from the opening/closing lid 4 via the lid so that it can be raised and lowered. The two gas springs 3, 3 each have an upper end 3a pivotally connected to the back surface of the storage box 1, and a lower end 3b pivotally connected to the opening/closing lid 4, so that the storage box changes its inclination as it expands and contracts. 1 can be raised and lowered.

However, after subsequent use, the following was discovered. In other words, this storage device used an expensive gas spring with a locking mechanism to stop the storage box at the desired position, but the left and right gas springs had an unbalanced expansion/contraction length and expansion/contraction speed. This means that it is difficult to keep the storage box level with just the gas spring.

[Purpose of invention]

In view of the above circumstances, the object of the present invention is to provide a storage device having a mechanism that allows the storage box to be fixed in any position when the storage box is raised or lowered without tilting.

[Disclosure of invention]

In order to achieve the above object, this invention is such that a storage box is suspended in a vertically movable manner from a plate suspended from a height via a gas spring acting in a linear direction, and the storage box is lifted and lowered by the plate. The storage box is guided by rails provided in the vertical direction on both the left and right sides of the body, and includes locking means for holding and fixing the storage box horizontally at a desired height position when going up and down. There are two latches arranged at equal heights on the back of the box, a spring that biases each latch horizontally in one direction, and a handle provided at the bottom of the storage box that moves the latches in the opposite direction to the spring biasing direction. The storage box is fixed at a desired position by inserting the latch into a hole formed at the same height on each side wall of the left and right rails. The gist is the storage device that is used. Hereinafter, this invention will be explained in detail based on drawings showing embodiments.

The basic structure of the entire storage device according to this invention is as shown in FIGS. 1 and 2.
Therefore, as shown in these figures, a box 9 is embedded in the ceiling 7 to form an opening 8, and an opening/closing lid 4 is rotatably attached to one side of the opening 8 via a hinge 6. There is.

As shown in FIGS. 1 and 2, the opening/closing lid 4 is connected via metal fittings 11 to gas springs 10 that are pivotally mounted on opposing sides of the ceiling opening 8. That is, the gas spring 10 is
The tip of the rod 12 is pivotally connected to the metal fitting 11. As a result, the opening/closing lid 4 is always biased in the direction of the opening 8 (in the direction of closing). Therefore, if you stop holding the opening/closing lid 4 in position after it has rotated from the opening 8, the rod 12
is contracted, and the opening/closing lid 4 is rotated in the direction of the opening 8.

As shown in the figure, a storage box 1 is attached to an opening/closing lid 4, which is a plate, via gas springs 3, 3. The two gas springs 3, 3 are arranged in a symmetrical eight-shape. By rotating the opening/closing lid 4, the storage box 1 can be moved in and out of the opening 8. Each gas spring 3 has one end 3
a is pivotally attached to a position close to the hinge 6 on the back surface of the storage box 1, and the other end 3b is pivotally attached to the opening/closing lid 4. As shown in the figure, the opening/closing lid 4 is provided with rails 5 on both left and right sides facing the back surface of the storage box 1. A roller 1a that fits into each of the rails 5 is provided on the back surface of the upper end of the storage box 1.
The rollers 1a are adapted to be guided by rolling on the rails 5 when the storage box 1 is raised and lowered.

When the storage box 1 is stored in the ceiling opening 8 or during the rotation of the opening/closing lid 4, the locking means 2 (described later) is locked at a fixed position near the hinge part.
Fixed by Each gas spring 3 is
When the storage box 1 is located at the top, the rod 3c is fully extended. Further, when the rod 3c is in a contracted state (a state in which the storage box 1 is lowered), it has a biasing force in the direction in which it extends.

The locking means 2 is constructed as follows. In other words, as shown in Figure 3, storage box 1
Two U-shaped support fittings 23 are fixed at equal height positions near the inner sides of both rails 5, 5 on the back surface. A hole 23a drilled in each vertical piece of the support fitting 23 and a spring 22 installed inside the support fitting 23.
A latch 21 is inserted into the hollow part of the holder. The spring 22 is located within the support fitting so that one end of the spring 22 is connected to the latch 21.
The latch 21 is fixed to the flange 21a, and the other end is fixed to the inner vertical piece of the support fitting, thereby constantly urging the latch 21 outward (towards the rail 5). In Figure 3, 23b
are screws that fasten the support fittings 23 to the storage box 1.

A latch 2 is installed at the same height on each side wall of the two rails 5, 5 arranged on the left and right sides of the opening/closing lid 4.
Several holes 5a into which the tips of the holes 5a can be inserted are formed. Therefore, by inserting the tip of the latch 21 into the hole 5a by the biasing force of the spring 22,
The storage box 1 is fixed in that position. Since the two latches 21, 21 are arranged at the same height,
When the latch 21 is secured, the storage box 1
will be stably fixed and held horizontally.

The end of the latch 21 opposite to the rail 5 side is pivoted to one end of the horizontal arm 24. Arm 2
The other end of 4 is pivoted to a rotating plate 25 which is rotatably pivoted at the center of the back surface of the storage box 1 at approximately the same horizontal position as the support fitting 23 . Rotating plate 2
5, one end of a vertical arm 26 connected to a drive handle 27 is also pivoted. Drive handle 27
is located at the lowest end of the storage box 1, and one end thereof is pivoted to the lower end of the vertical arm 26, as shown in FIG. The drive handle 27 is pivoted to the storage box 1 at a position closer to the arm 26 than the center thereof. By grasping the handle 27 and bringing it close to the fixed handle 28, the vertical arm 26 is pushed up and the rotating plate 25 is rotated. Then, the latch 21 is pulled back in the direction opposite to the biasing direction of the spring 22, and the latch 21 is released.

[Effect of idea]

Since this invention is configured as described above, when the storage box is raised or lowered, it can be placed in the desired position.
Moreover, it has the effect of fixing without tilting.
