Description

  The present invention relates to a storage for storing articles and the like.

2. Description of the Related Art A storage for storing articles and the like includes a side wall and a bottom plate that define a storage space, and has a structure in which articles are placed and stored on the bottom plate. Such storage may need to be moved. For example, in stationary storage furniture such as cabinets, baskets, and bookshelves, when stored, articles stored to facilitate movement. It was a troublesome work.
In addition, there is storage furniture in which wheels such as casters are provided at the bottom, but when there is no need to move, there is a problem that the wheels are exposed and the appearance is not good.

In the following Patent Document 1, a movable storage furniture that can be moved as needed is proposed.
This movable storage furniture is configured such that a carriage housing space is formed between the furniture body and the floor surface, and the carriage is accommodated in the carriage housing space. Further, a female screw member is provided on the bottom plate of the furniture body, and a male screw member that advances and retreats from the lower surface of the bottom plate toward the upper surface of the carriage is screwed into the female screw member to constitute a furniture body lifting means.
In the movable storage furniture, with the above configuration, when movement is necessary, the male screw member is advanced from the bottom surface of the bottom plate toward the carriage housing space, and is brought into contact with the top surface of the carriage. Furthermore, by advancing the male screw member, the furniture body is lifted with respect to the cart, and the caster of the cart can roll. On the other hand, when it is not necessary to move, the lower end of the side plate of the furniture body is in contact with the floor surface by retracting the male screw member from the carriage housing space and away from the upper surface of the carriage, and the furniture body is connected to the floor surface. It is set as the structure stably mounted.

JP 2002-85177 A (see FIG. 1)

  However, in the movable storage furniture described in Patent Document 1, it is necessary to move the furniture main body up and down with respect to the carriage accommodated in the carriage accommodation space. That is, since it is necessary to move up and down the furniture main body in which the article is stored, in the state of moving, the load of the stored article and the furniture main body is applied to the lifting means, and the operation of the lifting means is relatively large. There was a problem of requiring power. In addition, since the furniture main body in which the article is stored moves up and down, it is also conceivable that the stored article moves in the furniture main body when moving up and down.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a storage that can be easily switched between a state in which the storage is prevented from moving and a state in which the storage can be easily moved. .

  In order to achieve the above object, a storage according to the present invention has a wheel on the lower side, and stores a bottom plate on which articles are placed, the bottom plate so as to surround the bottom plate, and the bottom plate. And a support portion that supports the bottom end of the side wall in a state of floating from the floor surface. To do.

  In the storage according to the present invention, a stepped portion facing the upper surface of the peripheral edge of the bottom plate may be provided around the inner peripheral surface of the side wall.

  In any one of the storages according to the present invention, the storage may have a substantially rectangular shape in plan view, and the support portions may be provided in the vicinity of the four corners.

  In any one of the storages according to the present invention, the support portion is supported in a state where the lower end of the side wall is floated from the floor surface, and the support state is released, and the side wall is allowed to descend. It is good also as a structure switched to two steps with the cancellation | release state to perform.

  In any one of the storages according to the present invention, the support portion is attached to the inner peripheral side of the side wall, and a slide portion that can be moved up and down with respect to the bottom plate, and an advanced state of the slide portion. And holding the lower end of the side wall by bringing the slide portion into an advanced state and bringing the bottom plate side end portion of the slide portion into contact with the contacted portion on the upper surface of the bottom plate. It is good also as a structure supported in the state floated from the floor surface.

According to the storage according to the present invention, when it is not necessary to move the storage (normal use state or the like), the lower end of the side wall can be obtained by lowering the side wall (downward position). Is brought into contact with the floor surface, the movement of the storage is blocked, and is not easily moved (hereinafter sometimes referred to as a movement blocking state). In this state, since the lower end of the side wall stored so as to surround the bottom plate is in contact with the floor surface, the wheels are not exposed and the appearance is good.
On the other hand, when it is desired to move the storage, the wheels of the bottom plate are rotated by moving the side wall upward with respect to the bottom plate and supporting the lower end of the side wall from the floor surface by the support portion. The storage can be easily moved (hereinafter, sometimes referred to as a movable state).
Switching from the movement preventing state to the movable state can be performed by moving the side wall upward with respect to the bottom plate having wheels and supporting the lower end of the bottom plate from the floor surface by the support portion. It is not necessary to move the whole or the bottom plate up and down. Therefore, the articles stored in the storage and placed on the bottom plate do not move due to the vertical movement of the entire storage or the bottom plate.
In addition, since it is not necessary to move up and down the bottom plate on which the article is placed and the load of the article is applied, the load of the placed article and the bottom plate is switched between the movement-prevented state and the movable state of the storage. Can be done without receiving.

  In the storage according to the present invention, if a stepped portion facing the upper surface of the peripheral edge of the bottom plate is provided around the inner peripheral surface of the side wall, the gap between the side wall and the bottom plate is made inconspicuous. Can do. That is, since the storage according to the present invention is configured such that the side wall can be moved up and down with respect to the bottom plate, the relative movement between the inner peripheral surface of the side wall and the outer peripheral end surface of the bottom plate is allowed. Although it is necessary to provide a clearance (clearance), the clearance can be made inconspicuous by providing the stepped portion. It is also possible to prevent the stored items from falling from the gap.

In any one of the storages according to the present invention, if the storage is substantially rectangular in plan view, and the support portions are provided in the vicinity of the four corners, the lower end of the side wall is floated from the floor surface, When the movable state is set, the loads on the side walls and the like can be efficiently supported by the support portions provided near the four corners.
Further, by providing support portions in the vicinity of the four corners, the support portions can be made inconspicuous even when the support portions are provided so as to protrude from the inner peripheral surface of the side wall.

  In any one of the storages according to the present invention, the support portion is supported in a state where the lower end of the side wall is floated from the floor surface, and the support state is released to allow the side wall to descend. If the structure can be switched to two stages of the release state, for example, the movement prevention state can be achieved by a simple operation, compared to a case where the support unit switches between the movement prevention state and the movable state by a screw operation or the like. It is possible to switch between the released state and the support state in which the movable state is achieved.

  In any one of the storages according to the present invention, the support portion is attached to the inner peripheral side of the side wall, and a slide portion that can be moved up and down with respect to the bottom plate, and an advanced state of the slide portion are maintained. And a bottom plate side end portion of the slide portion is brought into contact with a contact portion on the upper surface of the bottom plate so that the lower end of the side wall is placed on the floor. If the structure is supported so as to float from the surface, the vertical movement direction of the side wall and the advancing and retreating direction of the support portion with respect to the bottom plate of the slide portion are both in the vertical direction. Accordingly, the support portion can be operated in conjunction with or in association with the vertical movement of the side wall. For example, compared with an aspect in which the support portion is configured by a slide portion that moves forward and backward in the horizontal direction, Good operability when switching between the movable states.

Next, an example of the movement blocking state and the movable state in the storage 1 configured as described above and a procedure for switching these states will be described with reference to FIGS. 1 and 4.
<Movement blocked state>
In this movement prevention state, as shown in FIG. 1, the support 5 is in the release state, and the bottom plate side end portion 5 c (see FIG. 4B) of the slide column 5 a is on the upper surface of the bottom plate 6. The amount of advance of the slide column body 5a from the lower end opening of the guide tube 5e is small, being regulated by contacting the contacted portion 6b (same surface as the upper surface in the illustrated example). In this state, the entire bottom plate 6 including the casters 7 is accommodated in the lower portion 3c of the side wall 3, and the lower end 3a of the side wall 3 is in contact with the floor surface 9 over the entire circumference. . In this state, the storage 1 is prevented from moving due to the frictional resistance between the lower end 3a of the side wall 3 and the floor surface 9, and is not easily moved.

<Switching to movable state>
When switching from the movement preventing state to the movable state, as shown in FIG. 4A, the lid 2 is removed from the upper end of the side wall 3, and the side wall 3 is lifted upward. As the side wall 3 moves upward, the guide tube 5e fixed to the crosspiece member 4 moves upward. On the other hand, the slide column body 5a is in a state where the bottom plate side end portion 5c is regulated by the contacted portion 6b of the bottom plate 6 by its own weight and is not moved up and down. Thus, the side wall 3 is lifted, the slide column 5a and the guide cylinder 5e are relatively moved in the vertical direction, and the locking projection 5b of the slide column 5a is the lower end of the slide groove 5f of the guide cylinder 5e. The locking projection 5b is rotated and the slide column body 5a is rotated along the circumferential direction, and the locking projection 5b is locked in the locking groove 5g to obtain the locked state.

<Moving state>
If each support 5 is locked as described above, the slide column body 5a is held in a state where the slide column body 5a is greatly advanced from the lower end opening of the guide tube 5e, and the bottom plate side end portion 5c is held by each contact of the bottom plate 6. As shown in FIG. 4A, the side wall 3 is supported by the support members 5 with respect to the bottom plate 6 with the lower end 3a of the side wall 3 floating from the floor surface 9 as shown in FIG. .
In the above support state, the lower end 3a of the side wall 3 is lifted from the floor surface 9, so that the frictional resistance between the lower end 3a of the side wall 3 and the floor surface 9 is eliminated, and the casters 7 provided on the bottom plate 6 roll. It becomes possible, and it will be in the movable state which can move the said storage 1 easily.
In this movable state, when the storage 1 is viewed from the side, a part of each caster 7 is exposed from the lower opening of the side wall 3, and the bottom plate 6 is stored in the lower part 3 c of the side wall 3. is there.

It should be noted that a space to the extent that each caster 7 can roll is formed between the floor surface 9 and the lower end 3a of the side wall 3 in the movable state. The amount of advancement of the slide portion (in this embodiment, slide column body 5a) to the bottom plate 6 side with respect to the attachment portion (in this embodiment, guide tube 5e) to the side wall 3 in the support 5 and the holding state for holding the advancement state. What is necessary is just to set suitably the position of the part (In this embodiment, the latching protrusion 5b of the slide pillar 5a, and the latching groove 5g of the guide cylinder 5e).
Further, for example, the above-described locking grooves may be provided at a plurality of locations along the height direction of the slide groove so that the degree of floating of the lower end 3a of the side wall 3 from the floor surface 9 in this movable state can be changed. Good.

<Switching to the movement blocking state>
On the other hand, when switching from the movable state to the movement-preventing state, on the contrary, by changing each support tool 5 from the locked state to the released state, the slide column body 5a and the guide cylinder 5e Movement along the relative vertical direction is possible. Thereby, the lowering of the side wall 3 is allowed, the side wall 3 is lowered, the lower end 3a of the side wall 3 is brought into contact with the floor surface 9, and the switching to the movement preventing state is performed.

As described above, in the storage 1 according to the present embodiment, the movement preventing state in which the storage 1 is prevented from moving and the movable state in which the storage 1 can be easily moved are easily switched. Can do.
Further, the side wall 3 is moved upward with respect to the bottom plate 6 having the casters 7, and the side walls 3 are supported with respect to the bottom plate 6 by the respective support tools 5 in a state where the lower end 3 a is floated from the floor surface 9. Since it is configured, it is not necessary to move the entire storage, the bottom plate, etc. up and down. Therefore, the article 8 stored in the storage 1 and placed on the bottom plate 6 is not moved by vertical movement. Further, since there is no need to move the bottom plate 6 on which the load of the article 8 is loaded and the load of the article 8 is moved up and down, switching between the movement preventing state and the movable state of the storage 1 is performed. This can be done without receiving a load of 6 or the like.

Furthermore, in this embodiment, the storage 1 is substantially rectangular in plan view, and each support 5 is provided in the vicinity of its four corners. When floated and in the movable state, the load on the side wall 3 and the like can be efficiently supported by the respective support tools 5 provided in the vicinity of the four corners.
Moreover, even when each support tool 5 is attached to the crosspiece member 4 and the support tool 5 protrudes from the inner peripheral surface 3b of the side wall 3 as in the present embodiment, it is provided near the four corners. These support tools 5 can be made inconspicuous.

  Furthermore, in the present embodiment, each of the support members 5 described above is in the locked state, and supports the lower end 3a of the side wall 3 in a state where it floats from the floor surface 9, and releases this support state. In this structure, the side wall 3 can be switched to a two-stage state in which the side wall 3 is allowed to descend. Therefore, for example, compared to a case where a support portion that switches between the movement-prevented state and the movable state by a screw operation or the like is used, a release state that makes the movement-prevented state and a support state that makes the movable state by a simple operation And can be switched.

In particular, in this embodiment, as the side wall 3 moves up and down, the guide cylinder 5e attached to the side wall 3 and the slide column body 5a relatively move up and down due to the weight of the slide column body 5a and the restriction of the bottom plate 6. Since it is configured to move, switching between the locked state and the released state of each support tool 5 can be performed by a simple operation.
That is, in the above-described support 5, when the side wall 3 is moved up and down, the slide column body 5 a moves forward and backward with respect to the guide cylinder 5 e attached and fixed to the side wall 3. In addition, for example, the operability is better than the aspect in which the support portion is configured by a slide portion that moves back and forth in the horizontal direction.

In the present embodiment, the storage 1 is illustrated as having a substantially rectangular shape in plan view. However, the storage case 1 may have another polygonal shape, circular shape, or elliptical shape in plan view. May be. In this case, a plurality of support tools similar to those described above may be arranged uniformly, or if there are corners, support tools may be provided in the vicinity of each corner.
In the present embodiment, the lid body 2 is illustrated as a lid body 2 that closes the opening for opening and closing the article of the storage 1 so as to be freely opened and closed. An openable door-type lid body may be used. Alternatively, such a lid may not be provided.

Furthermore, in the present embodiment, the article loading / unloading opening of the storage 1 is open upward, but it may be open to the side. In this case, a top plate may be provided at the upper end of the side wall, and an opening may be provided in a part of the side wall. For example, when it is set as a rectangular parallelepiped shaped storage, it is good also as an aspect which comprises a side wall with a pair of side plate, a back plate, and a base ring. In this case, for example, the back plate portion is always in a state of floating from the floor surface without adopting an aspect in which the entire periphery of the lower end 3a of the side wall 3 can be brought into contact with the floor surface as in the present embodiment. Also good. Thus, the contact of the lower end of the side wall with the floor surface is not limited to a mode in which the entire periphery can be contacted, and so as not to impair the appearance in the installation state (normal use state) of the storage, It is good also as an aspect which can contact | abut only a part of lower end of a side wall in the state lowered | hung according to the frictional resistance with the floor surface, etc. in a movement prevention state.
In addition, in the case where the lid is provided in the side opening in this way, an open / close door type lid may be used.

Furthermore, in the drawing, the side wall 3 is shown as being integrally formed in a rectangular tube shape, but four side walls 3 may be configured by connecting four plate members, or integrally. It may be formed.
Further, when the movable state is set, a handle or the like may be provided on the outer peripheral side of the side wall so that the side wall can be easily lifted.
Furthermore, in this embodiment, although the aspect which attached the four casters 7 to the lower surface of the baseplate 6 is illustrated, the number of these casters 7 and the location to provide are not restricted to the thing of an illustration. For example, it is good also as an aspect which provides the some recessed part opened downward on the lower side of a baseplate, accommodates a part of caster in each these recessed parts, and attaches each.
Furthermore, the wheels for easily moving the storage 1 are not limited to the casters 7 whose direction is freely changed, and the wheels may be configured by roller members or rolling members whose directions are fixed. Or you may make it comprise a wheel combining these roller members and a caster member.

Moreover, in this embodiment, although the step part which faces the peripheral part upper surface 6a of the baseplate 6 is comprised by the crosspiece member 4 fixed to the inner peripheral surface 3b of the side wall 3, such a crosspiece-like step part is formed. May be formed integrally with the side wall. Or you may make it form such a step part by making the thickness of a side wall into different upper and lower sides, or making the vertical cross-sectional shape of a side wall into a staircase shape.
Or you may make it not provide such a step part. In this case, you may make it attach each above-mentioned support tool 5 to the internal peripheral surface 3b of the side wall 3 directly.
Further, a retaining portion such as a projection for preventing the bottom plate 6 from slipping off or a cross member may be provided on the inner peripheral surface of the side wall 3 near the lower end 3a. According to this, for example, when the movable state is set, it is possible to prevent the side wall from being lifted up excessively, and to prevent the bottom plate 6 from coming out of the lower opening of the side wall 3.

Furthermore, the support portion for supporting the side wall 3 with respect to the bottom plate 6 in a state where the lower end 3a of the side wall 3 is floated from the floor surface 9 is not limited to the above-described support 5 and various modes can be applied. is there. In addition, the number of support tools and the mounting position are not limited to the positions shown in the figure, and when a plurality of support tools are provided in the vicinity of the four corners, or when the above-described step portions are provided, the above steps are provided. It is good also as an aspect which provides the slide part which advances / retreats toward the upper surface of the baseplate 6 from the lower surface (step surface) of a part. That is, it is good also as an aspect which accommodates a slide part in a side wall or a crosspiece member so that advancement / retraction is possible.
Moreover, you may make it provide instead of the aspect which provides a support tool in a side wall side like this embodiment in the baseplate side. For example, a guide portion attached to the bottom plate, a slide portion that moves up and down along the guide portion toward a contacted portion (for example, a step portion) on the side wall, and a holding portion that holds the advanced state of the slide portion It is good also as a thing provided. In such a state, the slide part is in the advanced state, and the forward end of the slide part is brought into contact with the contacted part of the side wall so that the lower end of the side wall is lifted from the floor surface. Thus, the side wall can be supported by the support portion with respect to the bottom plate. That is, a guide part is provided on either the inner peripheral side of the side wall or the bottom plate, and a slide part (advance / retreat part) that can be advanced and retracted vertically along the guide part and toward the other contacted part. ) And a support portion for supporting the advanced state of the advance / retreat portion may be provided.

Further, as shown in the figure, the support portion is not limited to the support portion in which switching between the locked state and the released state is performed in two stages, and for example, the support portion may be configured by a female screw portion and a male screw member. That is, the female screw portion is a guide portion provided on either one of the above, the male screw member is the slide portion (advance / retreat portion), and the slide portion (advance / retreat portion) is advanced as the screwed portion between the male screw member and the female screw portion. The male screw member may be grasped as a holding portion that is held in a state where the male screw member is advanced and retracted by a screw operation toward the other contacted portion. According to this, the vertical movement of the side wall is interlocked by this screw operation. Alternatively, in the present embodiment, the slide column body 5a as the slide portion is regulated by its own weight and the upper surface of the bottom plate 6, and the side wall 3 is moved up and down in conjunction with the vertical movement of the side wall 3, thereby serving as a guide portion. The support 5 is configured to move forward and backward with respect to the guide cylinder 5e. However, the slide column body 5a may be manually slid and switched in two steps as described above.
Furthermore, in this embodiment and each of the above-described examples, a configuration in which a slide part (advance / retreat part) that moves up and down is brought into contact with a contact part of the bottom plate or the side wall and the lower end of the side wall is supported in a floating state. However, a relative vertical movement between the bottom plate and the side wall may be locked by a slide part (advancing and retreating part) that moves back and forth in the horizontal direction, and the lower end of the side wall may be supported in a floating state from the floor surface. For example, a slide part (advancing / retracting part) such as a slide piece or a male screw member that advances (protrudes) from the peripheral end part of the bottom plate toward the inner peripheral surface of the side wall, and a guide for guiding the sliding part (advancing / retracting part). On the other hand, a concave portion that receives the slide portion (advance / retreat portion) may be provided on the inner peripheral surface of the side wall, and the support portion may be configured by the slide portion (advance / retreat portion) and the concave portion. Similarly to the above, the support portion having the slide piece that advances and retreats in the horizontal direction can be switched in two stages by sliding, and the operability is good.

Alternatively, instead of providing a slide part (advance / retreat part) that advances and retreats in the vertical direction or the horizontal direction as described above, and a holding part that holds the slide part (advancement / retraction part) in the advanced state or a receiving recess, For example, the bottom plate (or side wall) is provided with a guide portion having a vertical sliding groove and a horizontal locking groove, and the side wall (or bottom plate) is provided with a locking member that can be rotated or slid in the horizontal direction. The locking member may be moved along the slide groove and the locking groove of the guide portion of the bottom plate (or the side wall) so as to be a support portion that can be switched between the locked state and the released state.
In addition, in the support portion that can be switched in two stages as described above, a mode in which a spring member or the like is provided in the guide portion or the like so that the side wall is lifted to automatically lock the side that supports the floated state. It is good.
Further, in each of the above examples, the mode in which the operation for switching the support portion is performed from the inner peripheral side of the side wall has been described, but the operation portion of the support portion is configured so that the operation can be performed from the outer peripheral side of the side wall. You may do it.
