3v, and a horizontal bar 23h. That is, the opening side frames 21 and 23 are formed in the same shape that is straight along the connection surface P so that the hood can be connected without any gap on the connection surface P.

The opening-side frame (rod-like body) 21 is removably inserted into a shaft hole (described below) formed in the fittings 41, 41.
Numeral 1 is attached to pivot shafts 27a provided on the wall surfaces 13b of the connecting tray 13. Further, the width between the lower ends of the opening-side frame 21 is equal to the wall thickness 13b.
It is smaller than the distance b by the clearance required for mounting and turning. Thereby, the opening side frame 2
1 can rotate between an installation state erected along the connection surface P and a storage state stored in the storage tray 11 along the tray surface 11a. In addition, the opening side frame 21 is stored in a state of being floated from the tray surface 11 a by the length of the fitting 41.

Hereinafter, a support structure for supporting the opening-side frame 21 will be described in more detail with reference to FIGS. The rotating structure according to the present invention is applied to the supporting structure, and the rotating structure is configured to be rotatable around a wall surface 13b as a supporting member and a rotating shaft 27a. It is composed of an attachment (rotating body) 41 connected to the wall 13b via the rotation shaft 27a, and a tray surface 13a capable of contacting and supporting the lower surface 41a of the attachment 41.

The mounting member 41 is an L-shaped bent bracket formed along the wall surface 13b. One side of the L-shape has a shaft hole into which the lower end of the opening side frame 21 is inserted and supported. It is a formed tubular portion (supporting portion) 41b.
Further, the other side of the L-shape is formed at the end located farther from the cylindrical portion 41b through the rotating shaft 27a.
The flat portion 41c is axially attached to 3b.

In the installation state in which the opening side frame 21 is erected along the connecting surface P, the lower surface 4 of the flat portion 41c
1a is in contact with and supported by the tray surface 13a. for that reason,
The attachment 41 and the opening-side frame 21 can rotate toward the end-side frame 22 while the opening-side frame 23
Rotation to the side is prevented. That is, the tray surface 13
“a” functions as rotation preventing means for preventing rotation of the attachment 41 as a rotating body and fixing the same in a predetermined direction with respect to the wall surface 13b as a support member.

The lower surface 41a of the flat portion 41c is
The ends 41d and 41e are machined into an arc shape centering on the rotation shaft 27a. Thereby, the mounting fixture 4
It is possible to prevent the end portion 41d from being pressed against the tray surface 13a and the end portion 41e from being pressed against the mounting member 41 supporting the opening side frame 23 when the rotating member 1 rotates, thereby realizing a smooth rotation of the mounting member 41. Is done.

On the other hand, the end side frame 22 includes two vertical posts 22v, 22v and a horizontal bar 22h and is formed in a substantially U-shape. Similarly, the end side frame 24 includes two vertical posts 24v, 24v and a horizontal bar 24h, and is formed in a substantially U-shape.

The opening-side frame (rod-like body) 22 is removably inserted into fittings (rotary bodies and support parts) 42 whose lower ends are straight extensions of the vertical posts 22v. Then, the end side frame 22
Are connected to rotating shafts (connecting members) 28a, 28a provided on walls 11e, 11f (see FIG. 3) as supporting members via shaft holes formed in the distal ends of the mounting members 42, 42. Axle-mounted.

The width between the lower ends of the end frames 22 is smaller than the distance between the wall surfaces 11b and 11d by the clearance required for mounting and turning. In addition, the tips of the attachments 42 are located at the lower end corners of the walls 11e and 11f near the wall 11c, respectively.
a. As a result, the end-side frame 22 pivots between an installation state in which the storage tray 11 is installed upright along the wall surface 11c and a storage state in which the storage tray 11 is stored along the tray surface 11a. be able to. Further, since the rotating shafts 28a are formed on the extension of the end side frame 22, the end side frame 22 is stored in the storage tray 11 without any interval along the tray surface 11a. Thus, the opening-side frame 21 is overlaid on the folded end-side frame 22, and is folded down.

More specifically, when the end frame 22 is installed upright, the side surface 42
a is in contact with and supported by the wall surface 11c. Therefore, the attachment 42 and the end-side frame 22 can rotate toward the opening-side frame 21, but are prevented from rotating outward from the tray unit 10. That is, the wall surface 11c serves as a rotation preventing means for preventing rotation of the mounting member 42 as a rotating body and fixing the mounting member 42 in a predetermined direction to the wall portion 11e (or 11f) as a supporting member. Function.

The both side surfaces of the mounting member 42 are formed into circular arcs with their ends 42d and 42e being centered on the rotating shaft 28a. Accordingly, it is possible to prevent the end 42d from being pressed against the wall surface 11c and the end 42e from being pressed against the tray surface 11a during rotation of the fixture 42, and smooth rotation of the fixture 42 is realized.

On the other hand, the opening-side frame 23 is constructed in the same manner as the opening-side frame 21, and the end-side frame 24 is constructed in the same manner as the end-side frame 24 so as to be erected and housed. Omitted.

When the opening-side frames 21 and 23 and the end-side frames 22 and 24 are erected, the fittings 41 and 42 are respectively engaged with the locking members 30 (for example, using elasticity such as a leaf spring). More preferably, it is temporarily fixed so as to maintain an upright state. The locking strength of the locking member is set such that the opening side frames 21 and 23 and the end side frames 22 and 24 can be locked and released by the locking member with one hand.
Accordingly, the opening side frames 21 and 23 and the end side frames 22 and 24 can be reliably erected, and a gap can be prevented from being generated between the closed opening side frames 21 and 23.

Further, as shown in FIG. 2 (a), when a storage object S such as a garbage bag is stored in the interior of the simple type house 1, either one of the opening side frames 23 and 21 is connected to the connection surface. P in the direction away from the opening side frame 23.2
An interval larger than the size of the storage object S may be made between 1. Here, in order to facilitate the movement of the opening-side frames 23, 21, the handles 29, 29 are attached to the horizontal bars 21h, 23h.
May be attached.

Further, as shown in FIG. 4, on the opening side frames 21 and 23, springs (biasing means) 31...
It may be attached to. Thus, by opening the trunk in the stowed state and raising the end side frames 22 and 24 which are tilted upward and stored, the opening side frames 21 and 23 which are tilted downward and stored are springs 31. Is automatically erected by the
Can be automatically extended to a hood-like installation state. When the container S is accommodated in the interior, the opening-side frames 21 and 23 are moved by applying an external force in a direction away from the connection plane P to accommodate the container S, and then the handle 29 is released. The moved opening-side frame 21 (or 23) is automatically returned to the connection plane P by the urging force of the spring 31, and the opening is closed. That is, the tray surface 13a serving as the rotation preventing means is a means for exerting a force, which balances with the urging force of the spring 31 serving as the urging means, on the attachment 41.

Also, in place of the support structure shown in FIG.
It is also possible to use the frame support structure shown in FIG. As shown in the drawing, the support structure includes two mounting members (rotating members) that are mounted on the supporting member 52 via a supporting member (supporting member) 52 and rotating shafts (connecting members) 54.
51 (51); springs (biasing means) for constantly biasing each of the fittings 51 in one of the rotation directions.
53;

The above-mentioned support fitting 52 is a fitting having an L-shaped cross-section composed of a horizontal surface portion 52b fixed to the tray surface 13a via bolts and a vertical surface portion 52a perpendicular to the horizontal surface portion 52b. . Note that the vertical surface portion 52a
Also serves as the wall surface 13b described above.

The vertical shaft 52a is provided with the rotating shafts 54.5.
4 are formed with arc-shaped guide holes (guide portions) 52c, 52c having substantially the respective centers.
51 is a vertical surface 52 through pins (protrusions) 51c 51c inserted (inserted) into the guide holes 52c 52c.
a. The arc-shaped guide hole 52
Each of c and 52c is formed so as to have a central angle of about 90 degrees toward the in-plane direction of the horizontal plane portion 52b with reference to the in-plane direction of the connection plane P. Also, the guide hole 52c
The width of 52c is slightly larger than the shaft diameter of the pins 51c.

The above-mentioned fittings 51, 51 are provided with pins 51c,
A main body 51a, 51a supported by the support fitting 52 via the rotating shafts 54, 51c;
51b.

The main body 51a is provided with a vertical post 2
A flat metal fitting whose longitudinal direction is the extension direction of 1v / 23v, and an end portion 51 located near the horizontal surface portion 52b.
d and 51d are formed into a substantially semicircular shape centered on each of the rotating shafts 54. In addition, the support portion 51b
51b is formed with a shaft hole into which the opening-side frames 21 and 23 are inserted and supported, and has a main body 51a.
Pinned to.

The springs 53, 53
A coil spring wound around 54, one end of which is provided on a fixing tool 5 provided on a horizontal surface portion 52b of the support fitting 52;
5.55, and the other end is attached to the mounting tool 51.5.
1 is engaged. The attachments 51 supporting the opening side frame 21 are always attached to the end side frame 24 by the springs 53 and the attachments 51 supporting the opening side frame 23 are attached to the end side frame 22 by the springs 53. Be inspired.

The attachments 51 can be independently rotated one by one, and the following description will be made with reference to an example of the turning operation of the attachment 51 that supports the opening side frame 21.

With respect to the opening side frame 21, the spring 5
When a force (external force) is applied in the opposite direction (indicated by an arrow A in FIG. 5A) to the urging force by the force 3, the opening-side frame 21 (that is, the mounting tool 51) at the time when the force exceeds the urging force
Can be turned in the direction of the end-side frame 22. When the attachment 51 rotates, the pin 51c fixed to the attachment 51 moves in the guide hole 52c. Therefore, the mounting tool 51 can rotate in the direction of arrow A until the pin 51c and one end 52c 'of the guide hole 52c are in contact with each other, that is, until the opening frame 21 is parallel to the tray surface 11a. It is.

On the other hand, when the force in the direction of arrow A is released,
The opening side frame 21 receives the urging force of the spring 53 and automatically returns to the opening side frame 23 direction. When the pin 51c comes into contact with the other end 52c "of the guide hole 52c, further rotation of the fixture 51 is prevented, the opening-side frame 21 returns to the connecting surface P, and the opening is closed. That is, in the frame support structure shown in Fig. 5A, the mounting tool 5 is formed by the pin 51c and the guide hole 52c.
One rotation preventing means is constituted.

The end portion 51d of the attachment 51 is formed into a substantially semicircular shape as described above, and when the attachment 51 rotates, the attachment 51 is moved to the horizontal surface portion 52b of the support fitting 52 or the adjacent attachment. 51 can be prevented from being pressed.

In FIG. 5 (a), a guide hole 52c formed as a guide portion and a projecting portion so as to penetrate the vertical surface portion 52a of the support fitting 52, and is fixed to the fixture 51 and freely penetrates the guide hole 52c. Although the combination with the pin 51c described above has been described as an example, the present invention is not particularly limited to this. For example, an arc-shaped groove portion (guide portion) formed on the vertical surface portion 52a and centered on the rotation shaft 54, and a projection structure (projection portion) inserted into the groove portion so as to be relatively movable with respect to the groove portion. Can also be used.

Further, depending on the shape of the main body 51a of the mounting member 51, an arcuate and concave guide may be used.
In a, a protrusion may be provided on the vertical surface 52a of the support fitting 52. In this case, when the attachment 51 rotates, the lower end of the attachment 51 and the horizontal surface 5
2b may be pressed against, for example, the attachment 51
Is required to be spaced apart from the horizontal surface 52b.

Further, it is also possible to use a support structure shown in FIG. 5B instead of the frame support structure described above. This support structure is obtained by processing the lower ends of the contact surfaces of the fittings 51 into gears in the support structure shown in FIG. In other words, two attachments (rotating bodies) 51, 51 are connected to the support fittings (supporting members) 52 via different rotating shafts (connection members) 54, 54, and each of the attachment portions 51 51 has arc-shaped gear portions 51e around the corresponding rotation shafts 54, 54,
The gear 51e has a support structure in which the gears 51e mesh with each other.

The gear 51e provided on the mounting tool 51
Are each 1/4 arc-shaped (center angle 90 degrees) provided so as to face the corresponding guide hole 52c with the corresponding rotation shaft 54 as a reference point, and the pin 51c is connected to the guide hole 52c.
When moving from one end 52c 'to the other end 52c ", the gears 51e and 51e are always meshed with each other. Therefore, if one of the supports 51 and 51 is rotated, the supports 51 and 5 are rotated.
The other one is driven in the opposite direction.

More specifically, by moving the opening side frame 21 in the direction of the end side frame 22 (direction of arrow A), the opening side frame 23 is driven in the direction of the end side frame 24 and When the frame 21 returns to the connection surface P by the urging force of the spring 53, the opening side frame 23 can also return to the connection surface P by the follow-up due to the meshing between the gear portions 51e and 51e and the urging force of the spring 53. it can. Therefore, for example, when storing items S such as garbage bags inside the simplified house 1, one of the opening-side frames 21 and 23 is moved in a direction away from the connecting surface P, so that the opening S is opened. The other of the side frames 21 and 23 can also be driven in a direction away from the connection surface P, and the opening interval between the opening frames 21 and 23 can be easily secured.

For the convenience of storing the opening side frames 21 and 23 in the storage trays 11 and 12, respectively, the fittings 51 and
More preferably, 51 indicates a rotation operation at the same angle about the corresponding rotation shafts 54. Therefore, the number of teeth provided on each of the gear portions 51e and the distance from the corresponding rotating shaft 54 to the gear portions 51 are usually set to be equal. FIG. 5 (b)
In the configuration shown in FIG.
The gear 51 is formed by processing a part of the gear 51 into a gear shape. However, the gear portion may be provided separately from the fixture 51 as long as the gear 51 can be rotated integrally with the corresponding fixture 51.

Further, since one of the fittings 51 is driven by the other, the opening frame 21 (or the opening frame 23) can be compared with the frame supporting structure shown in FIG. The force required to move the same in the direction of the end-side frame 22 (or the end-side frame 23) by about the same amount increases. For this reason, it is more preferable to set the urging force of the spring 53, which is the urging means, to be weaker than in the support structure shown in FIG.

In the frame supporting structure shown in FIG. 5B, one of the fittings 51 is driven by the other by the meshing of the gears 51e as described above. Therefore, one of the springs 53, the guide hole 52c as the rotation preventing means and the pin 51
Either one of the combinations with c can be omitted.

In some cases, the guide holes 52c
It is also possible to omit all 52c and pins 51c. Even in this case, 1) providing the spring 53 on at least one of the attachments 51, 2) that the gear portions 51e, 51e are meshed, and 3) the attachments 51, 51 By satisfying the condition that they are in contact with each other (for example, the connection plane P),
The opening / closing operation (rotating operation / rotation preventing operation) of the opening side frames 21 and 23 described above can be realized.

The opening-side frames 21 and 23 and the end-side frames 2 and 24 are erected or the storage trays 11.
2 is the same as that of the support structure shown in FIG.

As shown in FIG. 6, springs (biasing means) 32... For biasing the end frames 22 and 24 in the direction in which they are erected (one direction in the rotational direction) are also attached. It can also be attached to the tools 42. Thus, by opening the trunk in the stowed state, the opening side frames 21 and 23 and the end side frames 22 and 24 are automatically erected, and the nets 25 and 26 are automatically spread to the hood-like installation state. Can be. In this case, in order to prevent the end frames 22 and 24 from jumping up when the end frames 22 and 24 are folded over the opening frames 21 and 23 and stored, the storage trays 11 and 12 are provided with the end frames. A frame fixing member (not shown) for fixing the frames 22 and 24 may be provided. That is, when the springs 31 are provided only on the opening side frames 21 and 23, the springs 31 are pressed from above by the end side frames 22 and 24, so that it is not necessary to provide such a frame fixing member.

Further, as a supporting structure for supporting the end side frames 22 and 24, for example, a frame supporting structure shown in FIGS. 7A and 7B can be applied. The support structure includes a support (support member) 62; an attachment (rotary body) 61 that is pivotally mounted on the support 62 via a pin 64 that is a rotation shaft (connection member). .
In the following description, among the four support structures for supporting the end-side frames 22 and 24, a support structure provided on the wall surface 11b to support one end of the end-side frame 22 will be described as an example. I do.

The mounting bracket 62 includes mounting surfaces 62c, 62c fixed to the wall surface 11b via bolts;
A support surface portion 62a connected to the mounting surface portions 62c and 62c via the pins 64; connecting surface portions 62b and 62b for connecting the mounting surface portions 62c and 62c to the support surface portion 62a and fixing the support surface portion 62a in a floating state from the mounting surface portions 62c and 62c; It is a bracket composed of:

A pin 62c (projection A) is fixed to the support surface 62a, and a linear guide hole 62d as a guide hole A is formed in the support surface 62a.
Is supported by the support surface portion 62a via a pin 64 loosely inserted (inserted) into the guide hole 62d. The width of the guide hole 62d is formed slightly larger than the shaft diameter of the pin 64. Further, the support fitting 62 is attached to the wall surface 11b so that the linear guide hole 62d has a vertically extending direction.

The mounting member 61 includes a main body 61a supported by a support metal 62 via pins 64 and 62c,
The support portion 61b is included.

The main body 61a is a substantially square plate-like metal fitting, and has a guide hole 6 having an arc portion 63a and a linear succeeding portion 63c provided continuously with the arc portion 63a.
3 (guide portion A) is formed. This guide hole 63
Is slightly larger than the shaft diameter of the pin 62c, and the pin 62c is freely inserted (inserted) into the guide hole 63. The arc portion 63a is centered on the pin 64,
9 from the 1d direction to the side 61e direction (in the direction of arrow B)
It is provided so as to have an angle of 0 degree (the central angle of the arc), and the linear succeeding portion 63c is connected to the side 6 of the main body 61a.
It is provided to have an extension direction parallel to 1c and 61d.

On the other hand, the supporting portion 61b is
And a shaft hole in which one end of the end-side frame 22 is inserted and supported.
It is pinned along one side 61c of 1a.

As shown by the solid line in FIG. 7A, in a state before the end frame 22 is erected (a state in which the frame is stored in the storage tray 11, etc.), the mounting tool 61 has vertical sides 61e and 61f. It is supported and fixed to the support bracket 62 so that it faces in the direction, that is, the support portion 61b (that is, the end frame 22) and the subsequent portion 63c are parallel to the tray surface 11a.

The pin 64 is located at the upper end 62d 'of the guide hole 62d, and is at the center of the arc 63a as described above. For this reason, the mounting tool 61 is set in the direction in which the end frame 22 is erected around the pin 64 (FIG. 7).
(In the direction of arrow B in (a), it can be rotated up to 90 degrees.

When the attachment 61 is rotated 90 degrees in the direction of arrow B, the pin 62c relatively moves in the arc portion 63a and reaches the boundary 63b between the arc portion 63a and the following portion 63c (FIG. 7A). Medium and two-dot chain lines). At this time, the mounting portion 61
Side 61c, 61d, support portion 61b, guide hole 62d,
In addition, the subsequent portion 63c is oriented vertically.

At this time, the guide hole 62d and the trailing portion 63c extend in the opposite direction with respect to the pin 64 and the pin 62c, respectively. More specifically, the guide hole 6
2d extends downward with reference to the pin 62c,
3c extends upward with reference to the pin 64. Therefore, if the mounting tool 61 is dropped in the direction of gravity (directly below), the pin 64 fixed to the mounting tool 61 is moved to the guide hole 62.
d moves from its upper end 62d 'to its lower end 62d "(relative movement with respect to the guide hole 62d), and the pin 62c fixed to the support fitting 62 moves inside the following part 63c from its boundary 63b to its tip 63c. 'And the state shown in FIG. 7B is obtained.

In the state shown in FIG. 7B, since the pin 62c is disengaged from the arc portion 63a and is located at the following portion 63c, the rotation of the attachment 61 is stably prevented. Further, the support portion 61b is oriented vertically, and the end side frame 22
Is erected perpendicularly to the tray surface 11a. The storage of the end side frame 22 in the storage tray 11 is performed in the opposite operation to that described above, that is, when the pin 62 c is
This can be easily performed by pulling the mounting tool 61 directly upward until it comes into contact with b, and then rotating the mounting tool 90 by 90 degrees in the direction opposite to the arrow B.

In the above description, “guide hole 62
d and the subsequent portion 63c are sequentially connected to the pin 64 and the pin 62c.
Are extended in the opposite directions with respect to each reference. "In other words, the intermediate point between the pin 64 and the pin 62c (more precisely, the intermediate point between the axes of the pins 64 and 62c) is used as the reference. This means that the guide hole 62d and the following portion 63c satisfy the relationship of “substantially point symmetry”. here,
"Substantially point symmetry" means that a line segment connecting the center points in the width direction of the guide holes 62d and a line segment connecting the center points in the width direction of the succeeding portion 63c are point-symmetric, for example, And the guide hole 62d and the subsequent portion 63c are formed with different widths.

The shape of the subsequent portion 63c is not particularly limited as long as it is a concave structure extending in a direction deviating from a virtual extension line of the arc portion 63a so as to be distinguished from the arc portion 63a.

Further, the end side frames 22 and 24 do not necessarily need to be erected perpendicularly to the tray surfaces 11a and 12a. That is, the size of the mounting angle of the support portion 61b to the main body portion 61a and the size of the central angle of the arc portion 63a can be appropriately set in accordance with the desired standing angle of the end side frames 22 and 24.

7 (a) and 7 (b), a guide hole 62d as a guide hole A and a projection A are provided on the support fitting 62 side.
A pin 62c is provided as the
A guide hole 63 as a guide portion A and a pin 64 as a rotation shaft are provided on one side, but the guide portion A and the rotation shaft are provided on the support fitting 62 side. Alternatively, a configuration in which the protrusion A and the guide hole A are provided on the attachment 61 side may be adopted.

The end side frames 22 and 24 according to the present invention
May further have a configuration shown in FIG. 7 (c). The difference between this support structure and the support structure shown in FIGS. 7A and 7B is that 1) a guide hole 65 corresponding to the guide hole 62d is formed on the mounting fixture 61 side, and 2).
The point is that a pin 66 corresponding to the pin 64 is fixed to the support fitting 62 side. That is, the attachment (rotary body) 61
A guide hole 63 as a guide portion A and a guide hole 65 as a guide hole portion B into which a pin 66 serving as a rotation shaft is relatively movably inserted are provided, and a support fitting (support member) is provided.
62 has a configuration in which a pin 62c as a projection A is provided.

[0086] The arc portion 63a is formed so that the pin 66 serves as its center when the mounting member 61 rotates, and the pin 62c is formed between the following portion 63c and the guide hole 65 by the boundary portion 62b. In order, the pins 62
c and the pins 66 are formed so as to extend in the same direction (both upwards) with respect to each other (FIG. 7C).
Middle, see the location shown by the two-dot chain line).

Therefore, if the attachment 61 is dropped in the direction of gravity (directly below), the pins 6 fixed to the support
6 is a guide hole 65 extending from its lower end 65 'to its upper end 6'.
The pin 62c, which is relatively moved to 5 "and is fixed to the support bracket 62,
From the front end portion 63c 'to the end portion 63c', and the state shown by the solid line in FIG.

In the state shown by the solid line in FIG.
Since 2c is displaced from the arc portion 63a and is located at the succeeding portion 63c, the rotation of the attachment 61 is stably prevented. Further, the support portion 61b is oriented vertically, and the end side frame 22 is erected perpendicularly to the tray surface 11a.
The storage of the end-side frame 22 in the storage tray 11 is performed in the reverse of the above-described operation, that is, the mounting tool 61 is pulled up directly until the pin 62c contacts the boundary 63b. Fixture 61 in the opposite direction to its standing
This can be easily performed by rotating the lens by 0 degrees.

In the above description, "the protrusion moves relative to the inside of the guide" means 1) when the protrusion moves inside the guide, and 2) when the guide moves relative to the protrusion. Shall mean both. This is because the relationship between the projection A and the guide A, the rotation axis and the guide hole A
The same applies to the relationship with B.

The nets 25 and 26 are connected to the storage tray 11.
The hoods supported by the opening-side frames 21 and 23 and the end-side frames 22 and 24 and connected to each other at the connection plane P are formed on 12. Also,
The material and shape of the nets 25 and 26 can be appropriately selected according to the application.

The opening-side frames 21 and 23 and the end-side frames 22 and 24 are removably inserted into fittings 41 and 42 and assembled to the storage trays 11 and 12 and the connection tray 13. As described above, since the hood portion 20 of the simplified house 1 can be completely removed from the tray portion 10, maintenance such as cleaning and component replacement can be easily performed.

Next, the operation when the simplified type house 1 having the above configuration is used for collecting dust will be described.

The trunk, which is the simple house 1 in the housed state, is brought to the garbage collection point, the trunk is opened, and the end frames 22 and 24 that are housed by being tilted upward are tilted downward. Opening frame 2 stored
1 and 23 are automatically erected by springs 31 ...
The nets 25 and 26 are automatically spread to the hood-like installation state, and the central opening of the hood 20 is closed.

When storing a garbage bag (storage object S) in the simplified type house 1, one of the handles 29 of the opening side frames 21 and 23 is used.
With one hand to form an opening and accommodate the garbage bag. And after the garbage bag is stored, the handle 2 that holds the frame
9 is released, the opening-side frame 21 (or 23) is automatically returned to the connecting surface P by the urging force of the springs 31 and the opening is closed.

At the time of collection by a garbage truck, both the opening side frames 21 and 23 are moved to an open position at a predetermined angle and fixed by a fixing stopper (not shown), so that the center of the hood portion 20 is enlarged. Open and take out the trash bag.

After use, when folding the hood section 20 into the tray section 10, the opening side frames 21 and 23 are moved down to the storage position, and the end side frames 22 and 24 are laid thereon. Here, the nets 25 and 26 are automatically folded into the storage trays 11 and 12 as the end frames 22 and 24 are tilted. For this purpose, for example, a wire with a habit or a loose spring is appropriately disposed on the nets 25 and 26.

When the storage trays 11 and 12 with the hood 20 folded are folded in a trunk shape, for example, the end of the storage tray 12 is lifted and the connection tray 13 is lifted.
The trunk is closed so as to cover the storage tray 11 centered on. At this time, the ends of the wall surfaces 12b and 12d of the storage tray 12 bent at 90 degrees are
When the storage tray 12 is rotated by more than 90 degrees to contact the end of the tray surface 13a extending to the outside of the b.13b, the connection tray 13 also supports the connection portion with the storage tray 11 as a fulcrum. To rotate. In this manner, the connected storage trays 11 and 12 and the connected tray 13 can be easily folded into a trunk simply by rotating one storage tray so as to cover the other storage tray above.
