Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a foldable storage bed unit.

<Prior art and its problems> A bed that pivots to a shelf for storing small items, books, etc. so that it can be freely converted between a folded state in an upright position and a unfolded state in a horizontal position, and a folding method for use in the unfolded state. Although retractable bed units are known, conventional products are as long as the human body, so even when folded, they are still quite bulky and very heavy, making them particularly difficult to transport up stairs in apartment complexes. The problem is that it is extremely inconvenient and requires hard labor to access the elevators and the entrances of each home.

<Means for solving the problems> The present invention was devised to eliminate such inconveniences and to improve stability and robustness during use, and for this purpose, a structure as a foldable storage bed unit was devised. Above, an organizing shelf made of wood with an integrated frame in the form of a square box with an open front; and also made of wood with an integrated framework in the form of a square box, slightly smaller than the organizing shelf and with an open top to accommodate mats. and a bed with supporting legs, with the rear side of the bed facing the lower part of the storage shelf from the inside, and the both sides of the bed being assembled to the both sides of the storage shelf by a pair of horizontal pivot shafts. ,
The bed is designed as a unit that can be converted into a horizontal unfolded state and a folded state in which the open front of the storage shelf is closed. Both connecting plates are formed separately from the middle position in the longitudinal direction and are attached and integrated at the dividing boundary of the organizing shelf and the dividing boundary of the bed, respectively, by screw fasteners or other fixing devices. In addition to being detachably connected, a horizontal fulcrum shaft extending along the axis of the rotation axis is separately extended from both connecting plates attached to the dividing boundary of the bed, and one fulcrum shaft is located corresponding to the fulcrum shaft. Alternatively, the bed can be organized by installing a plurality of leg seats integrally upright from the dividing boundary of the bottom plate of the organizing shelf, and rotatably fitting the fulcrum shaft to the upper end of the leg seats. When folded against a shelf,
It is characterized by the fact that the leg seat is set to be buried inside it.

<Example> Below, the specific configuration of the present invention will be described in detail based on the illustrated example.As is clear from the overall unfolded usage state of Figures 1 and 2, the bed unit can be used to store books and various small items. It consists of a unit body consisting of a sorting shelf A, such as the above, and a bed B, which is attached to the front side of the sorting shelf A with a rotational support that can be opened and closed, and the bed B can be folded as shown in Figures 3 and 4. In addition to being able to be stored inside the organizing shelf A, the bed unit as a whole can also be divided into separate types as shown in FIG. 5 during transportation.

First, the organizing shelf A is made of decorative plywood or other wood made of a top plate 11, a bottom plate 12, a pair of left and right side plates 13, and a back plate 14, and is integrated into a square box shape with a constant depth W1 with an open front. ing. 1
5 is a horizontal partition plate that divides the inside of the frame into upper and lower halves, and the upper space is used for organizing books, small items, etc., and the required number of shelves 1 whose mounting height can be adjusted are installed.
6 and vertical partition plates 17 to further subdivide the area. On the other hand, the lower space defined by the horizontal partition plate 15 is arranged so that the bed B can be freely rotated and partially received without any trouble.

Moreover, the sorting shelf A is divided into two pieces, left and right, from the middle position in the longitudinal direction (left and right direction), and the dividing line is indicated by the symbol C in the figure. A pair of adjacent horizontal connecting plates 18 are also attached and integrated in advance at the boundary. The pair of left and right connecting plates 18 are removably connected to each other via screw fasteners 19 using a plurality of bolts and nuts or other suitable fixing devices.

In that case, the depth dimension W2 of the connecting plate 18, the partition plates 15, 17, and the shelf board 16 is shorter than the overall depth dimension W1 of the above-mentioned organizing shelf A, so that the bed B can be placed in front of them. Acceptance and storage space is now secured. In other words, the depth dimension W3 of the storage space is set to be slightly larger than the thickness dimension T of the bed B including the mat 20, and the bed B is rotated into the upright folded state as shown in FIG. At this time, it can be received and buried in the storage space of the organizing shelf A without any problem, and the overall size can be made smaller and flat.

In the figure, the connecting plate 18 is replaced by a horizontal partition plate 15.
In other words, the partition plate 15 is made to hang long enough to penetrate into the space below the partition plate 15, so as to increase the strength of the organizing shelf A itself. Although the circular arc notch 21 is machined, as described above, it is only necessary that a part of the bed B can be received in the lower space without any hindrance to rotational movement.

Next, the bed B is made up of a bottom plate 22 made of plywood or other wood, a pair of left and right side plates 23, a front plate 24, and a rear plate 25, which are integrated into a square box shape with a constant depth and an open upper surface. Inside the mat 2
0 is inserted and fixed in a removable manner. The framework of the bed B has a similar shape, which is slightly smaller than that of the above-mentioned organizing shelf A, and thus the third and fourth beds have a similar shape.
When folded as shown in the figure, the open front surface of the organizer shelf A is neatly covered by the bottom plate 22 of the bed B. The size and shape of the bottom plate 22 are such that it slightly overhangs the outline of the frame formed by the pair of left and right side plates 23, the front plate 24, and the rear plate 25.

Also, the rear plate 25 of the bed B is connected to the front plate and both side plates 23.
The horizontal partition plate 15 of the organizer shelf A and the rear plate of the bed B when used in the unfolded state as shown in Figures 1 and 2. 25, so that no unsightly open space is created between the upper and lower sides.

In addition, the mat 20 is stabilized inside the frame of bed B by pillow material or perforated plywood, etc. not shown in the diagram.
It is also supported to prevent moisture from accumulating. 2
Reference numeral 6 indicates a ventilation hole that is opened through the front plate 24, side plate 23, etc. of the bed B in order to effectively release the moisture.

The bed B is attached to the lower part of the organizing shelf A by a pair of left and right horizontal pivot shafts 27 so as to be convertible between a horizontal unfolded state and an upright folded state. The attached balance weight D prevents the product from accidentally falling forward from the folded state and unfolding.

That is, in FIGS. 6 to 14, which clearly show this,
Reference numeral 28 denotes a metal dish box that is fixed and integrated from the inside to the lower part of each side plate 13 forming the sorting shelf A by a plurality of bolts 29. Tension coil spring 30
However, the overall structure is enclosed and installed in a parallel state. 3
Reference numeral 1 denotes an adjustment plate that locks the rear end of the spring 30, and is held by a plurality of fixing pins 32 that are integrally planted inward from the tray box 28 itself.
Adjustment bolt 3 inserted from the outside of the tray box 28
It is in a screwed relationship with 3. The adjustment bolt 33
By moving the spring 30 forward and backward in advance, the tension of the spring 30 can be changed in strength.
Note that 34 is an engagement elongated hole for the fixing pin 32, which is formed through the adjustment plate 31.

Further, 35 is a rotating plate that forms a pair with the above-mentioned adjustment plate 31, and the front end portion of the above-mentioned spring 30 is entirely locked to this rotating plate. Reference numeral 36 denotes a reinforcing plate attached and fixed to the outer surface of the side plate 23 of the bed B.
It is parallel to the inner rotating plate 35, and the rotating plate 35
and reinforcing plate 36 are assembled by a pivot 27 so as to be able to rotate integrally with each other. Moreover,
The rotation axis 27 also passes through the side plate 23 of the bed B and is exposed inside the bed B.

When the bed B is rotated by approximately 90 degrees to the folded state of standing up against the storage shelf A, the rotating plate 35, which rotates together with the reinforcing plate 36, opens the tray box as shown in Fig. 13. When the springs 30 in 28 are fully restored in the contraction direction and the bed B is rotated by about 90 degrees from its folded state to its horizontal unfolded state, the rotating plate 35 that also performs the rotational movement is activated. As shown in FIG. 14, the spring 30 is forcibly expanded.

Therefore, if the bed B is raised up from its unfolded state to a height position that reaches a certain rotation angle, the bed B will automatically rotate until it reaches the final position where it is completely buried inside the storage shelf A. However, the storage shelf A and the bottom plate 22 of the bed B are kept in a folded state in close contact with each other, so that even a child can operate the folding operation easily and without the risk of jamming the operator's hands.
On the other hand, when converting the bed B to its deployed state, such as laying it down horizontally, the tensile force of the spring 30 acts against the bed B.
There is no need to worry about the accidental falling down or the resulting impact.

The bed B is also divided into two pieces, a pair of left and right pieces, from the same dividing line C as the above-mentioned organizing shelf A, and a pair of adjacent connecting plates 37 are provided at the dividing boundary. It is also an integrated accessory. The connecting plate 37 reinforces the frame of the bed B, and spacers 3 are inserted in a certain mutual gap S facing each other, as shown in FIGS. 7, 8, and 16.
8 and are removably connected and integrated by screw fasteners 39 such as bolts and nuts and other fixing devices.

Reference numeral 40 denotes a pair of parallel fulcrum shafts extending horizontally from each of the connecting plates 37 toward the gap S, and as is clear from FIGS. It is located on the same line Y-Y that coincides with the axis. 41 is also the connecting plate 3
7 is a fixed plate fixed by screws 42 or the like, and a fulcrum shaft 40 is integrally welded thereto in a penetrating state as shown in FIG.

43 is a pair of leg seats facing into the mutual gap S of the connecting plate 37, and has an L-shaped cross section facing each other, and the lower end thereof is connected to the bottom 1 of the plate in the organizing shelf A.
It is fixed to the corresponding location of 2 with screws 44 or the like. The remaining upper end portion is fitted to the fulcrum shaft 40 so as to be relatively rotatable, and the bed B can rotate about the fulcrum shaft 40 while being stably supported from below by the leg seats 43. It has come to be used. In addition, 45 is a retaining ring.

46 is placed on the bed B in order to allow the rotating movement.
The leg seat relief notch is located on the dividing line C and is formed at the corner of the bottom plate 22 and the rear plate 25. In any case, bed B has its leg seat 4.
Since it is stably supported from below by 3, if it is divided into separate types,
This allows it to maintain its robustness even when used horizontally. Furthermore, when the bed B is folded upright with respect to the storage shelf A, the leg seats 43 are buried inside the bed.

However, although in the figure, the leg seat 43 and the fulcrum shaft 40 are attached to each of the divided bed B as a pair on the left and right, for example, it is possible to freely insert and remove the left and right pair of the fulcrum shaft 40 to fit the male and female. It is also possible to omit one of the leg seats 43 by using a double shaft.

Further, the ends of the pivot shafts 27 facing into the bed B are pivotally connected to the support legs 47 of the bed B, and when the bed B is unfolded, the support legs 47 are automatically exposed and the bed is opened. The supporting legs 47 are maintained in a stable supporting state, and when the bed B is folded, the supporting legs 47 are automatically buried so that they cannot be seen from the outside world.

That is, at the end of the pivot shaft 27 facing inside the frame of the bed B, as is clear from FIGS.
is fixedly installed, and a reciprocating rod 5 is connected to the distal end of the rotating arm 48 via a pivot pin 49.
The rear ends of 0 are connected. Reference numeral 51 is a sheath tube screwed into the threaded portion of the front end of the rod 50, which passes through the front plate 24 of the bed B, and is connected to the support leg 47.
The upper ends of the two are welded together so that they intersect at right angles. Therefore, the amount by which the supporting legs 47 protrude from the front plate 24 of the bed B can be adjusted in advance to be large or small depending on the degree to which the sheath tube 51 and the rod 50 are screwed together.

52 is an engagement pin that is integrally planted from the circumferential surface of the sheath tube 51; 53 is a frame plate that is fixed to the side plate 23 of the bed B from the inside with screws 54, etc.; It is held in a state where it passes through the frame plate 53. Reference numeral 55 denotes an arc-shaped grooved cam with an opening formed in the frame plate 53, into which the sheath tube 51 is attached.
The engagement pin 52 is always engaged.

When the bed B is rotated to the folded state, the reciprocating rod 50 is moved backward by the rotating arm 48, and this movement causes the engagement pin 52 of the sheath tube 51 to engage with the groove cam 55 of the frame plate 53. Via
The support leg 47 is integrated with the sheath tube 51 and rotates approximately 90 degrees as shown in FIG.
7 is in a buried state covered by the bottom plate 22.

Further, when the bed B is rotated from the folded state to the horizontal unfolded state, the advance/retreat rod 50
moves forward automatically, and the support leg 47 integrated with the sheath tube 51 rotates about 90 degrees in the opposite direction to move the bed B.
can be stably supported from below. The structure is such that there is no need to add a separate manual operation to move the supporting legs 47 of the bed B in and out.

<Effects of the invention> As described above, in the foldable storage bed unit according to the invention, there is a storage shelf A made of wood with an integrated frame in the form of a square box with an open front, and a storage shelf A made of wood as well. It consists of a bed B with support legs 47 integrated into the frame in a square box shape that is slightly smaller than the above and whose top surface is open so that the mat 20 can be received, and the rear of the bed B is inserted from the inside to a position below the above-mentioned organizing shelf A. While facing the side panels 13 of the storage shelf A, move the side panels 23 of the bed B to the left and right horizontal pivot shafts 2.
7, the bed B is defined as a unit body that can be converted into a horizontal unfolded state and a folded state in which the open front of the storage shelf A is closed. Both connecting plates 18 and 37 are formed as a pair of left and right pieces, divided from the middle position in the longitudinal direction, and attached and integrated to the dividing boundary of the organizing shelf A and the dividing boundary of the bed B, respectively. , all screw fasteners 1
9, 39 or other fixing devices, and both connecting plates 3 attached to the dividing boundary of the bed B.
From 7, horizontal fulcrum shafts 40 extending along the axis of the rotation pivot 27 are separately extended, while the fulcrum shafts 4
One or more leg seats 43 located corresponding to 0,
The fulcrum shaft 4 is integrally erected from the dividing boundary of the bottom plate 12 in the sorting shelf A, and the fulcrum shaft 4 is attached to the upper end of the leg seat 43.
0 is rotatably fitted, so that when the bed B is folded against the organizing shelf A, the leg seats 43 are set to be buried inside it.
This has the effect of reliably solving the problems of the prior art mentioned at the beginning.

That is, by removing the mat 20 from bed B and disassembling both the connecting plates 37 of bed B and both connecting plates 18 of organizing shelf A, it is divided into two separate types as shown in FIG. can,
In its compact and lightweight state, packaging and transportation can be carried out rationally.

In addition, since the bed B is supported not only by the pivot shaft 27 for rotation with respect to the storage shelf A, but also by the leg seat 43 attached on the dividing line C, the bed B cannot be unfolded horizontally when in use. The condition is also extremely stable.
It can be kept strong. Moreover, since the fulcrum shaft 40 that fits into the leg seat 43 is disposed on the same axis as the rotation axis 27, the rotation of the bed B with respect to the organizing shelf A is also extremely smooth and stable. Even children can easily perform this operation. Therefore, it can be said that it is extremely useful in practice.
