Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a mounting shelf that can be newly installed on an existing desk.

[Conventional technology]

2. Description of the Related Art Conventionally, a desk has a drawer similar to a shelf, in which documents, books, etc. are stored. This is a desk with sleeves, but if that is not enough, a separately purchased shelf can be placed on or next to the desk.

Also, some steel desks have shelves attached to them as an option.
In that case, there is a hole in the side wall made of iron plate stretched between the front and rear legs of the desk, and the shelf has a hook that can be hung on the hole. , a shelf can be attached to the inside of the desk. This creates a desk with sleeves.

[The problem that the idea attempts to solve]

Recently, as office automation has progressed, the number of devices brought in has gradually increased, and the current situation is that offices everywhere are becoming cramped, and there is no space left for shelves to store documents. It's inconvenient, and I often end up with piles of documents on my desk.

As mentioned above, desks have traditionally been equipped with drawers, but even if documents are placed in the drawers, it takes time to search for them, so it would be very convenient if a shelf suitable for holding documents was installed.

Conventionally, even when a shelf was specially attached to a desk, it was attached to the missing part of the drawer when there was no drawer as a sleeve, so the amount of storage for documents etc. increased compared to a general desk. It didn't turn out to be a big deal.

Furthermore, if a drawer is placed on a desk, the space above it becomes cramped, which is inconvenient for doing office work.

In view of the above-mentioned circumstances, this idea was developed so that it can be attached to even armchair desks with drawers, and even though the number of shelves is increased compared to conventional desks, office work can still be carried out. The purpose of the present invention is to provide a mounting shelf that causes no inconvenience when holding and allows documents to be taken in and out easily.

[Means for solving the problem] In order to achieve the above-mentioned object, this invention arranges shelf boards between the substantially fan-shaped side panels, so that a large number of shelf openings are opened at the end faces of the fan-shaped opening sides. Assemble the shelf, and at the fan-shaped base end of the shelf protrude the main fastening piece that fixes it to the rear wall of the foot space of the desk, and it is pivoted so that it can swing up and down, and the tip of the shelf has a structure that expands and contracts on both sides. Flexible suspension springs are connected, and a secondary fixing piece is attached to the upper end of both suspension springs to be fixed to the inner upper part of the foot space, so that the shelf is always held upward by the suspension springs.

[Effect]

Since the desk mounting shelf was configured as shown above,
When installing this on a desk, place it in the foot space of the desk and fix the main fastening piece to the inside of the rear wall.
Fix the secondary fixing piece at the tip of the suspension spring to the upper end of the rear wall or ceiling surface.

Then, the shelf is suspended so as to be able to swing up and down about the support shaft of the main fastening piece, and is held upward by the suspension spring, so that it is in the stored state.

Since the shelf is approximately fan-shaped when viewed from the side, it has a large swing range, and when facing upward, it can move toward the back of the desk.
In other words, it is in a retracted position, so even if you sit on a chair and put your feet into the space inside the desk, your feet will not rest on the shelf unless you specifically try to touch it.

In this closed state, the shelf opening faces upward and faces the ceiling of the shelf, so when you put documents in or take them out,
Push down the tip of the shelf by hand against the elasticity of the hanging spring. The shelf opening now faces forward, so you can hold it with one hand while putting in and taking out documents with the other. In order to perform this operation, it is necessary to withdraw one's feet from the foot space of the desk, but this is extremely easy as one only has to move them while sitting on a chair.

Once you have finished putting in and taking out documents, you can take your hand off the shelf.
The shelf will be lifted up naturally due to the elasticity of the hanging spring,
Since it is retracted to the back, you can now pull up your chair and go to your desk.

In addition, in this state, since the shelf opening faces upward, the documents are held stably within the shelf so as not to fall out.

The function of the main and sub-fastening pieces that are fixed to the inside of the desk is not particularly important as long as they can be easily fixed. For example, by screwing,
It may also be by engagement between the hole and the hook.

However, these days, many office desks are made of steel, so it is possible to make use of that material and use magnets for the main and sub-fastening pieces. In the case of a magnet, it can be attached with a single touch operation, and it is also easy to remove.

〔Example〕

Next, an embodiment of this invention will be described based on the drawings.

The drawing shows one embodiment, and the desk mounting shelf L has a pair of main fastening pieces 2 on each shelf 1,
2 and suspension springs 3, 3 are attached, and sub-fastening pieces 4, 4 are attached to the tips of both suspension springs 3, 3.

The shelf 1 is made of wood and is assembled by arranging a large number of shelf boards 6, 6, . . . between both side boards 5, 5. The side plates 5, 5 are substantially fan-shaped and are formed to gradually become wider from the base end to the distal end. Therefore, shelf boards 6, 6
The space between the shelves widens toward the tip in accordance with the fan shape, and the shelf openings 7, 7, . However, in order to prevent the distance between the shelf boards 6, 6 from changing drastically depending on the position, the side boards 6, 6 are not completely fan-shaped, but have their lower edges 8 inclined upward. Further, a handle 19 is attached to the lower surface of the tip.

Magnets 2a are used for both the left and right main fastening pieces 2, 2, and are incorporated into both ends of the fixed frame 9, so that the fixed frame 9 is swingably attached to the shelf 1.

The fixed frame 9 is made by connecting left and right magnet mounting boards 10, 10 with a bar 11, and for installation on the shelf 1, both magnet mounting boards 10, 10 are connected to each other by a bar 11.
A hole is provided in the center of the shelf 1, and a bearing hole 1 is provided at the base end of the shelf 1, into which a support shaft 13 is inserted between the side plates 5, 5.
4 and 14, the magnet assembly boards 10 and 10 are connected to the support shaft 13.

A coil spring is used for the suspension springs 3, 3, one end of which is connected near the tips of the side plates 5, 5, and a ring fitting 1 is attached to the outer surface of the side plates 5, 5 for connection.
6 and 16 are screwed together, and hanging springs 3 and 3 are hooked thereto.

Magnets are also used for the sub-fastening pieces 4, 4,
It is integrated into mounting boards 17, 17, and both mounting boards 17, 17 are integrally connected by a bar 18. By hooking and connecting the suspension springs 3, 3 to the bar 18, the sub-fastening pieces 4, 4 are attached to the ends of both suspension springs 3, 3.

As shown in FIG. 2, the magnets serving as the fastening pieces 2 and 4 are constructed by placing a magnet 2a inside a U-shaped iron plate 2b, and
The U-shaped legs of the iron plate 2b are configured so that they touch the steel plate surface of the desk so that the magnet acts strongly.

To attach the mounting shelf L to the desk D, insert the fixing frame 9 into the foot space S and insert it into the rear wall 2 of the desk D.
0, the main fastening pieces 2, 2 are fixed by the force of the magnet 2a, and then the sub-fastening pieces 4, 4 are applied above and fixed. Both fastening pieces 4, 4
are integrally connected by the bar 18, so
By holding the bar 18 by hand, both fastening pieces 4, 4 can be applied to the rear wall 20 at the same time.

Figures 3 and 4 show the state in which it is attached to the desk D and put away.If it is simply attached and put away, as seen in Fig. 4, it will be lifted up by the hanging spring 3 and the rear is the rear wall 2 of desk D
0, and the shelf opening 7 is close to the ceiling wall 21, but since the shelf 1 is approximately fan-shaped, the lower surface gradually becomes higher toward the front, creating a space S where you can fully put your feet under it. remains.

Fig. 3 (dotted chain line in Fig. 4) shows the state in which the shelf 1 is pushed down, which creates space S.
Although it is no longer possible to put one's feet into the desk D, the shelf opening 7 is open in front of the desk D, so documents, books, etc. can be taken in and out easily.

For the suspension spring 3, we simply used a coil spring, but we also used a telescoping arm (multiple links pinned together), and the telescoping arm stops expanding and contracting at its longest and shortest length by fitting the concave part and the convex part. If this is done, the shelf 1 will stop at the vertical position. In this way, the shelf 1 will be held in a constant raised state regardless of the weight of the documents and books, and even if you release your hand when lowering it, the shelf opening 7 will not allow you to put in and take out documents, etc. It will be easily held in the front-opening state.

[Effect of idea]

As explained above, according to this invention, not only can a shelf be attached to a desk with sleeves and drawers, but also the shelf is approximately fan-shaped and opens toward the shelf opening, so the shelf opening faces upward. When it is closed, there is no problem in inserting your feet into the desk, and you can use it like a normal desk. In addition, when putting in and taking out documents and books, the shelf opening can be opened forward by simply pushing down with your hand, and when you have finished putting in and taking out documents, etc., the elasticity of the hanging springs is automatically returned to the closed state, so the shelf opening can be opened to the front. It is also extremely easy to handle. Moreover, since it takes advantage of the previously unused space in the desk to put your feet in, it is especially useful for shelves and
It has the excellent effect of being extremely convenient for organizing documents and books in offices where there is not enough room to store office equipment.

Moreover, when the main and sub-fastening pieces are magnets, there is an effect that they can be easily attached to and removed from a steel desk.
