Description

[Detailed description of the invention] This invention is a cabinet in which the top plate can be used as a table surface as it is, for example, by folding it into a cabinet.
An extension in which at least two decks hinged to each other so as to be freely unfoldable are folded and stored so as to be freely unfoldable, and the decks are pulled out and unfolded as necessary to form a table surface flush with the above-mentioned top plate. table, or
As shown in FIGS. 1 and 2, the cabinet a is formed to be extendable and has at least two decks hinged so as to be foldable or unfoldable, so that the cabinet a can be folded and stored or pulled out and unfolded. In the state shown in FIG. 1 in which cabinet a is stored and reduced in size, its own top plates c and c' are butted together on the same plane to form a table surface, and from this state cabinet a is extended. , pull out the storage deck S, b' from the opening, unfold it, and open the above top plate C.
This invention relates to a folding table such as a telescoping table that forms a large table surface that is flush with , c'.

There is a conventional folding table as shown in Fig. 3 which has a supplementary meaning to the top plate of the cabinet mentioned above. d and connect this to the cabinet) a.
It is constructed so that it can be stored or pulled out by sliding on an axis e fixed inside.

However, in the case of the above-mentioned configuration, the deck S, b' slides on the axis e in an inclined position from the storage position shown by the solid line in the figure, and then is pulled out to one side (leftward in the figure). Since it is unfolded, and when it is stored, it slides on the axis e in the opposite way to the above, a considerable space f for the sliding movement of the deck S and b' is used for the side wall a of the cabinet a. ′
If not set between the ends of the deck and the deck, b'
cannot be laid out and placed on the side wall a', and for this reason, the distance between the cabinets a and the length l of the deck b' must be made larger than necessary.

In other words, only small decks can be accommodated at certain intervals, and therefore, conventional tables have the disadvantage that the cabinet is large compared to the table surface area.

Therefore, the present invention is an improvement to solve the above-mentioned conventional drawbacks.At least two decks are folded and hinged so that they can be unfolded, and the central part of the lower deck is folded and stored inside the cabinet. In addition to being connected by links, a guide shaft is provided on the cabinet so that the upper deck is guided during storage and withdrawal, and the link and the lower deck are connected from a line connecting the center of the guide shaft and the pivot points of the link and cabinets 1 to 1. By setting and configuring the pivot point with the cabinet in the upper direction, it is possible to store a larger deck with respect to the cabinet.

The drawings showing the embodiments of the present invention will be described in detail below.
In FIG. 4, reference numeral 1 designates a cabinet I, which forms substantially the body of the table, and is provided with an opening 2 directed upward.

3.4 is a deck which can be mutually folded into two, like the conventional one, and whose ends are connected by a hinge 5 so that it can be unfolded into a flat plate.

Then, a bracket 3a is vertically attached to the back surface of the approximately central part of the lower deck 3 so that the decks 3 and 4 can be folded in half and stored approximately horizontally within the cabinet screws 1 to 1 as shown in the figure. In addition to connecting with a link 6, a guide shaft 7 is provided near the opening 2 of the cabinet 1 to guide the upper deck 4 when the decks 3 and 4 are stored or pulled out.

Furthermore, in the present invention, when the decks 3 and 4 are in the stored state as shown by solid lines, the lower part of the In the illustrated case, the position of the pivot point Q between the deck 3 and the link 6 is set in advance so that it is slightly upward.

In this case, the link 6 is not expandable and has a fixed length, and when the decks 3 and 4 are stored, it is held at an angle as shown in the figure, and the decks 3 and 4 are connected to the opening 2 of the cabinet 1. The pivot point P is held slightly lower than the
By rotating the link 6 counterclockwise around , the pivot point Q moves in the direction of the opening 2, and the
Push up so that the drawer can be pulled out from opening 2,
At this time, the position of the pivot point P is set in advance so that the decks 3 and 4 do not move freely to the left in the figure, and are connected to the lower deck 3 at the pivot point Q.

Further, the guide shaft 7 is provided approximately on the extension of the non-cross section when the decks 3 and 4 are in the stored state, and as described above, the line R connecting the center O of the guide shaft 7 and the pivot point P of the link 6 Than,
The reason why the pivot point Q between the link 6 and the lower deck 3 is set slightly upward is to allow the decks 3 and 4 to be stored and held in the approximately horizontal state shown by the solid line in the figure without using a stopper or the like. This is to facilitate the expansion of drawers on decks 3 and 4.

In the above configuration, the decks 3 and 4 are folded and stored in the cabinet 1 in the state shown by the solid line in the figure.
When the end of the upper deck 4 is pulled up from the stowed state, the lower deck 3, which is hinged to this, will rotate counterclockwise on the drawing paper with the link 6 centered on the pivot point P. Because of this rotation, the pivot point Q between the link 6 and the deck 3 moves upwards, whereby the decks 3 and 4 are pulled up and protrude from the opening 2.

If the deck 4 is further pulled up and rotated clockwise, it will come into contact with the upper edges 1' of the cabinets 1 to 1 and become horizontal, as shown by the broken line in the figure, but at this time, the lower deck 3 will move toward the left on the drawing paper. While moving to the upper edge of the cabinet 1, it is horizontally placed on the upper edge of the cabinet 1, so that the bibulous plate 3.4 is pulled out and unfolded into a flat plate, forming a table surface.

When the decks 3 and 4 are pulled out and unfolded in this way, the link 6 is held tilted to the left of the perpendicular line passing through the pivot point P, so the decks 3 and 4 are moved back and folded. It is maintained in the expanded state without being crushed.

When the left end of the deck 3 is pulled up from the above-mentioned deployed state, the amphibious plates 3 and 4 are bent from the hinge 5, so when the deck 3 moves further to the right, the other deck 4 moves counterclockwise while being guided by the guide shaft 7. It rotates in the rotational direction and tilts toward deck 3,
It moves to above the opening 2 of the cabinet 1 while being gradually folded.

When the decks 3, 4 are then pushed into the cabinet 1-1, the link 6 rotates clockwise, so that the deck 3.4 is lowered and folded into the cabinet 1 at the same time.

Note that the guide shaft 7 guides the deck 4 during the above-mentioned pulling out and storage, respectively.

As explained above, according to the folding table of the present invention, the decks 3 and 4 which are hinged to each other so that they can be folded and unfolded are guided by the link 6 that connects the cabinet 1 and the deck 3, and the deck 4. It is supported by the guide shaft 7 and stored and held in the cabinet 1 in a folded state, and when one side end of the decks 3 and 4 is pulled up from the stored state, the link 6 rotates and the link 6 and By moving the pivot point Q with the deck 3 upward, the amphibious plates 3 and 4 are pulled up in a tilted state, and then protrude from the opening 2 and can be further expanded into a flat plate shape. When pulling out or storing the cabinet 1, the decks 3 and 4 move little in the left-right direction but move a lot in the vertical direction, so it is sufficient to make the internal dimensions of the cabinet 1 slightly larger than the width of the decks 3 and 4. This has the effect of allowing a larger deck to be stored in a cabinet of a certain size and making the table surface wider than in conventional cases.

In addition, the decks 3 and 4 are folded and stored or pulled out and unfolded using the guide shaft 7 as a guide by the rotation of the link 6, so that the folding and unfolding operations can be performed smoothly and easily. Since the pull-out means can be formed by one link 6 and the guide shaft 7, the structure can be simplified and manufactured at low cost.
