Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to storage furniture, particularly to improvement of the grounding portion thereof.

Conventional technology Conventionally provided storage furniture such as chests of drawers, water closets, bookshelves, cabinets, cabinets, etc.
The lower end of the architrave is designed to touch the installation surface such as tatami or the floor.

Problems to be Solved by the Invention Although such conventional storage furniture provides stability when installed, it is inconvenient because it cannot be easily moved when rearranging or moving. This problem can be solved, for example, by equipping storage furniture with casters, but this is not preferable because it lacks installation stability and makes the appearance unsightly.

The present invention was made with the aim of eliminating these conventional problems.

Means for Solving the Problem The present invention includes an externally operated cylinder installed at a suitable location within an architrave provided at the lower end of storage furniture.
The present invention relates to storage furniture characterized in that it is provided with a moving member that moves in and out of the lower end of the architrave as the piston rod of the cylinder advances and retreats.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the architrave of the storage furniture, 2 is a cylinder provided at a suitable position within the architrave 1, and 3 is a cylinder that protrudes and retracts from the lower end of the architrave 1 as the piston rod 21 of the cylinder 2 advances and retreats. It is a moving member.

The architrave 1 may be integrated with or separate from the main body 4 of the storage furniture, and the figure shows a case where it is separate, and a top plate 11 is integrally provided at its upper end.

The cylinder 2 is fixed downwardly on the lower surface of the top plate 11 at a suitable location within the architrave 1, for example at each corner thereof, and then the inside of the chamber 22 is connected to the side of the architrave 1 via a conduit 24. The front chamber 23 is connected to an inlet 25 for a control fluid, such as air, provided in the front chamber 23, while the interior of the front chamber 23 is communicated with the atmosphere via an intake/outlet port (not shown) (see FIG. 3). It is preferable that the injection port 25 is provided with various known types of check valves (not shown) that can be opened appropriately by external operation. As the air supply means, for example, a manual or foot-operated air pump, a motor-driven compressor, or the like may be used.

The moving member 3 is placed at the tip of the piston rod 21 of the cylinder 2 when the rod 21 is withdrawn.
It is provided so that it is immersed in the architrave 1 and protrudes downward from the lower end of the architrave 1 when advanced. In the diagram,
Although the case where the moving member 3 is provided directly at the tip of the rod 21 is shown, depending on the storage space,
It may be provided to move up and down at a position laterally shifted from the rod 3 via a suitable intermediate member. Casters are usually used as the moving member 3, but instead of the casters, for example, a slider molded from a synthetic resin with good lubricity may be used.

When the storage furniture according to the present invention is normally installed, the piston rod 21 is in the retracted position as shown in FIG. The lower end of the ring 1 is in contact with the installation surface and supports the entire weight of the storage furniture. Therefore, the installation condition is stable during this normal time,
Moreover, since the moving member 3 and other accessories are completely invisible from the outside, there is no difference in appearance from ordinary storage furniture.

Now, in the state shown in FIG.
When a fluid such as air is forced into the rear chamber 22 of the cylinder 2 through the piston rod 4 and the piston rod 21 is moved from the retracted position to the advanced position, the moving member 3 provided on the rod 21 moves below the lower end of the architrave 1. The architrave 1 protrudes from the architrave 1 and is grounded in place of the lower end of the architrave 1. Since all the weight of the storage furniture is supported by the moving member 3, the storage furniture can be easily moved using the moving member 3. This state is shown in FIG. 3, and the rear chamber 22 of the cylinder 2 maintains an air pressure that balances the weight of the stored furniture, for example, about 1 to 5 kg/cm ² .

When the injection port 25 is externally operated in the state shown in FIG.
1, while exhausting the air in the rear chamber 22, the moving member 3 sinks into the architrave 1 as the storage furniture descends, and conversely, the lower end of the architrave 1 It is grounded in place of member 3, and returns to the normal installation state shown in FIG. 1 again, in preparation for the next moving operation.

Effects As described above, in the present invention, the movable member is made to be able to come and go in and out of the architrave of the storage furniture, and the movable member is grounded in place of the architrave when projected, so that
Ease of movement can be ensured without compromising stability during normal installation or the external appearance, making it extremely convenient for moving or rearranging.

Fig. 1 is a vertical sectional view of the main part showing an embodiment of the present invention, Fig. 2 is a bottom view of Fig. 1, and Fig. 3 is the main part showing a situation in which the moving member is grounded in place of the architrave. FIG. In the figure, 1 is the architrave, 11 is the top plate, 2 is the cylinder, 21 is the piston rod, 22 is the rear chamber, 23 is the front chamber, 24 is the conduit, 25 is the injection port, and 3 is the moving member. It is.
