Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case where articles are placed in a horizontal state when a shelf is used, and when the shelf is not used, the shelf is rotated to be almost vertical to make space in front of the shelf. A mounting shelf that does not narrow, is attached to left and right columns that are stretched and fixed by stretching up and down.For example, on a kitchen sink, stretch the columns up and down between the sink and the hanging cabinet. The present invention relates to a mounting shelf that becomes a temporary storage shelf in accordance with a cooking operation when a plurality of shelves are fixed between the supports and a plurality of shelves are attached.

[0002]

2. Description of the Related Art Conventionally, when using a shelf board mounted on a wall,
There were mounting shelves that could be perpendicular or parallel to the wall, depending on when not in use. In addition, there was also a column that could expand and contract and be fixed by stretching it up and down. However, there is no combination of the above-mentioned mounting shelf and a strut support, and the mounting shelf which is placed leaning along the wall so as not to be in the way when not in use is very effective in its use. However, its commercial value was low because it was difficult to mount it on a wall surface, or it was not allowed to leave scratches such as screw holes on the wall surface.

[0003]

SUMMARY OF THE INVENTION The present invention is directed to a mounting shelf which can be placed horizontally when used as described above, and which can be placed vertically when not in use, without leaving a screw hole or the like on a mounting wall. It is an object of the present invention to enable a mounting shelf to be mounted at any desired position without being mounted or having a vertical wall surface.

[0004]

As means for solving the above-mentioned problems, the mounting shelf according to the first aspect of the present invention expands and contracts,
A strut fixed by being stretched up and down is opposed to the left and right, and a shelf is rotatably mounted on the front surface of the strut. When formed in this way, the column is fixed by extending the column up and down, and a rotatable shelf plate is provided on the front surface of the column. This eliminates the need for additional mounting brackets such as nails and screws, and further damages the mounting position. The mounting shelf can be installed without imposing. The mounting shelf according to the second aspect of the present invention is the mounting shelf according to the first aspect, wherein the base end of the shelf is pivotally supported, and the shelf is kept horizontal when the shelf is used.
It is characterized in that it is configured to maintain a substantially vertical state when not in use. When the shelf is formed in this manner, the shelf can be held in a horizontal state when used, the depth of the shelf can be widened and a large number of articles can be placed, and when the shelf is not used, the shelf is held in a substantially vertical state. , The work space can be widened and the work efficiency can be increased. A mounting shelf according to a third aspect of the present invention is the mounting shelf according to the first or second aspect of the present invention, wherein the left and right side frame supporting portions of the shelf board are pivotally connected to the left and right shelf board support fittings, respectively. The two shelves support brackets are engaged with appropriate positions of the left and right strut struts and a shelf is erected. With such a configuration, the rotatable shelf can be installed at an arbitrary height, so that the shelf can be installed at a height corresponding to the size and shape of the object to be mounted.

[0012] The assembling of the shelf is performed first by the side frame 12 of the shelf plate 12.
b is the upper support piece 13b and the lower support piece 13c of the shelf support 13.
And a shaft hole 12c formed in the side frame 12b of the shelf board.
And a shaft hole 13e provided in the shelf support 13 and aligning the shaft 14 from the outside to rotate the shelf 12 vertically between the upper support 13b and the lower support 13c of the shelf support 13. Support freely. A set screw 15 is screwed into the inward rear piece 13f of the shelf support 13 from the rear to fix the shelf 12 and the support 1 described later.

Next, the assembling of the column 1 will be described. A fixing device 4 composed of an inner cylinder 6 and a set screw 7 is covered and fixed to the upper end of the large-diameter outer tube column 2. The boss 9c of the height adjusting tool 5 composed of the base plate 8, the frame piece 9 and the rotating nut
Insert into the lower end of the box and fix it.

The inner tubular column 3 is a small-diameter round pipe in which a plurality of small holes 3a are arranged in a row. A hole in a cylindrical boss 3c provided at the upper end at the center of the lower surface of the pressure contact plate 3d of the approximately rhombic plate 3b in plan view. Then, the upper end of the small diameter pipe is inserted and fixed. When the lower end of the inner tubular column 3 is inserted into the inner cylindrical body 6 covered with the upper end of the outer tubular column 2, it becomes a stretchable column.

In order to install the mounting shelf, two columns and a shelf plate are prepared. First, the push screw of the column fixing member is loosened, and the outer column and the inner column are stretched and retracted. Temporarily install it between the upper frame and the lower frame where the table shelf is to be installed, obtain the approximate size, and screw it in until the tip of the set screw of the fixing tool faces the small hole of the inner pipe column. Disable stretching. Next, the set screw provided at the rear end of the shelf support is loosened, and the support is inserted from the inside into the gap between the rear end of the upper support piece of the shelf support and the rear piece of the shelf support. Then, the shelf board is fixed to the column by screwing in the set screw.

Then, the mounting shelf is set up between the upper frame and the lower frame at the place where the mounting shelf is to be installed, and the rotating nut of the height adjusting tool provided at the lower end of the outer tube is rotated. The support is fixed by extending the support and widening the space between the press-contact plate at the upper end of the support and the base plate at the lower end so that the support is stretched. The shelves can be relocated to any position up and down by loosening the push screw provided at the rear end of the shelf support even after the shelf is installed.

[0017]

According to the first aspect of the present invention, the column is fixed by vertically extending the column, and a rotatable shelf plate is provided on the front surface of the column, so that mounting brackets such as nails and screws are separately required. In addition, the mounting shelf can be installed without damaging the mounting location. According to the invention described in claim 2,
When the shelf is used, it is held in a horizontal state, the depth of the shelf is widened, and many items can be placed.When the shelf is not used, it is held almost vertically, and the depth of the shelf is reduced. Work space can be expanded and work efficiency can be improved. Claim 3
According to the described invention, the rotatable shelf can be installed at an arbitrary height, so that the shelf can be installed by changing the position of the shelf to a height corresponding to the size or shape of the mounted object. .
