Utility Model Registration No. 3124723

  In the above shelf device, when changing the height position of the shelf board, the shelf holder (connecting part side) is tilted upward, and the insertion board is removed from the locking hole to raise and lower the shelf holder with respect to the shelf column. On the other hand, since the insertion plate is simply inserted into the locking hole, the insertion plate comes off when the upward force is applied, and the shelf holder itself tilts up and drops off. is there.

  Further, since the shelf holder itself must be inclined when the shelf holder is attached or detached, a space capable of allowing the inclination in the shelf column is required. For this reason, the box-shaped shelf pillar (the front plate) protrudes larger than the mounting wall surface and narrows the accommodation space such as the closet, and there is a disadvantage that the appearance is bad.

  The present invention eliminates the above-described problems, can firmly hold the mounting state of the shelf support with respect to the shelf column, can be easily attached and detached, and can effectively utilize a narrow accommodation space such as a closet. It aims at providing the shelf apparatus excellent in external appearance.

In order to achieve this object, the shelf device of the present invention has the following configuration.
The shelf device is inserted into a pair of mounting columns and a pair of mounting columns arranged in a series of a plurality of left and right polygonal mounting holes at regular intervals in the plane of the flat plate portion where both sides are curved and the gap between the mounting walls is small. A shelf holder in which a pair of left and right insertion locking portions provided with a retaining portion at the leading end is urged outward, a linear inner short side that constitutes the polygonal mounting hole, and a linear shape It is characterized by comprising dropout prevention means comprising an outer long side and a displacement prevention oblique side connecting the lower end of the inner short side and the lower end of the outer long side.

  In the shelf apparatus having such a configuration, the pair of left and right insertion locking portions of the shelf support are urged in the expanding direction, while the shelf pillar has a linear inner short side that forms a polygonal mounting hole, Since a drop prevention means comprising a linear outer long side and a displacement prevention oblique side connecting the lower end of the inner short side and the lower end of the outer long side is provided, a pair of left and right insertion locks on the mounting hole By simply reducing the distance between the facing parts and inserting it, it can be easily installed and removed, making it easy to load and unload.

  Furthermore, the insertion locking portion inserted into the mounting hole and returned to the expansion state is prevented from moving in the shrinking direction by the displacement prevention oblique side, so that the mounting state is firmly and safely maintained, and it falls off from the mounting hole which is not intended. The fear of is resolved.

  In addition, because the shelf column is curved on both sides of the flat plate and the gap between the mounting wall and the mounting wall is small, the protrusion from the mounting wall to the front is small, and it is possible to use the storage space such as a closet with little space effectively. There is no protrusion and the appearance is good.

  Further, by attaching the cover body to the insertion inclined portion that is inclined upward in the outward direction of the shelf holder, the shelf board load placed on the upper surface of the cover body acts as a pressing force in the expanding direction on the insertion locking portion. Furthermore, it has an excellent effect of achieving the object of the invention, such as being able to strongly prevent the insertion locking part from falling off.

Hereinafter, specific embodiments of a shelf device according to the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of the shelf device.
The shelf device includes a shelf column 1, a shelf holder 3 that is attached to and detached from the shelf column 1, and a drop-off prevention means 2 that is provided in the mounting holes 14 and 14 a of the shelf column 1 itself.

  The shelf column 1 is a molded product made of sheet metal such as stainless steel, and includes a strip-shaped flat plate portion 11 and curved side surface portions 12 in which both sides of the flat plate portion 11 are bent inward. In the plane of the flat plate portion 11, screw holes 13 and a pair of left and right mounting holes 14, 14a having a predetermined interval are arranged in a column at appropriate positions.

The degree of curvature of the curved side surface portion 12 of the shelf column 1 is set such that a gap substantially corresponding to the thickness of the retaining portion 35 of the shelf support 3 described later is opened between the back surface of the flat plate portion 11 and the mounting wall surface X. .

  The shelf holder 3 is made of a metal such as a stainless plate, for example, and the rear ends of the opposing walls 31, 31 opened at a predetermined interval are connected via the connecting portion 32, and the opposing interval between the opposing walls 31, 31 is opened outward. Energized in the direction. The upper end 31b of the opposing walls 31 and 31 is provided with an insertion inclined portion 36 that extends and inclines upward.

Further, insertion locking portions 33, 33 are provided with the upper ends of the front ends 31a of the opposing walls 31, 31 extending forward, and a retaining portion in which the tips of the insertion locking portions 33, 33 are bent outward. 34 and 34 are provided.
Moreover, the lower part of the front end 31a of both opposing walls 31 and 31 forms the abutting parts 35 and 35 extended and bent inward. The abutting portion 35 is in contact with the surface of the flat plate portion 11 in a state where the insertion locking portions 33 and 33 are fitted in the mounting holes 14 and 14a.

  A cover body 4 is detachably disposed on the shelf receiver 3. The cover body 4 has an inclined groove portion 42 that is inclined upward and outward on the back side of both sides of the rubber rectangular flat plate 41. The rectangular flat plate 41 has a wall thickness 41a at the center and is gradually set to a thin wall 41b outward (see FIG. 6). The insertion inclined portion 36 is slidably fitted into the inclined groove portion 42, and a shelf board (not shown) is placed on the upper surface of the cover body 4.

  The drop-off prevention means 2 prevents the opposing distance between the opposing walls (insertion locking portions 33, 33) 31 and 31 biased in the opening direction in the reduction direction. This drop-off preventing means is disposed in the pair of left and right mounting holes 14 and 14a of the shelf column 1 itself. That is, the drop prevention means 2 constitutes the mounting holes 14 and 14a themselves.

  The pair of left and right mounting holes 14, 14 a are vertically long polygonal shapes opened symmetrically on the left and right sides of the imaginary width center Y of the flat plate portion 11, and have a straight inner short side 21 and a straight outer long side 22. And a displacement prevention hypotenuse 23.

  The displacement prevention hypotenuse 23 is set to the hypotenuse (see FIG. 5) connecting the lower end 21a of the inner short side 21 and the lower end 22a of the outer long side 22. 1 to 4 showing the embodiment, it is set as a hypotenuse that connects the inner side 24a of the flat bottom surface 24 continuous with the lower end 22a of the outer long side 22 and the lower end 21a of the inner short side 21.

  The reason why the same displacement prevention oblique side 23 is provided not only on the lower side but also on the upper side of the mounting holes 14 and 14a is that the shelf pillar 1 is used both upside down. 23 is not required.

  In the shelf apparatus having such a configuration, the shelf column 1 is screwed to the mounting wall surface X as shown in FIG. The front ends 12 a of the left and right curved side surface portions 12 are in contact with the wall surface X, and the opening interval (gap) 12 b between the wall surface X and the back surface of the flat plate portion 11 corresponds to the approximate thickness of the retaining portion 34. Therefore, the retaining portion 34 with little protrusion of the shelf column 1 and located in the gap is held between the flat plate portion 11 and the mounting wall surface X, and a stronger retaining is achieved.

  As shown in FIG. 6, the load W relating to the cover body 4 is such that the component force W1 of the shelf board load W placed on the upper surface of the cover body 4 is the opposing walls (insertion locking portions 33, 33) 31, 31. Acts as a pressing force V in the expanding direction, and further prevents the insertion locking portion 33 from falling off.

  As shown in FIG. 2, the opposing walls (insertion locking portions 33, 33) 31, 31 are pressed inward to reduce the distance between the spring-biased insertion locking portions 33, 33. In this state, the insertion locking portions (retaining portions 34, 34) 33, 33 are inserted into the corresponding mounting holes 14, 14a. In this state, as shown in the explanatory view of FIG. 7A, the insertion locking portions 33 and 33 are in contact with the inner short side 21.

  As shown in FIG. 3, when the pressure on the opposing walls (insertion locking portions 33, 33) 31, 31 is released, the insertion locking portions 33, 33 return to the current state in the expanding direction, and the retaining portions 34, 34. Is in contact with the outside of the mounting hole 14 (14a) in the plane of the flat plate portion 11. In this state, as shown in the explanatory view of FIG. 7B, the insertion locking portions 33 and 33 are in contact with the outer long side 22.

  Here, when the shelf support (insertion locking portions 33, 33) 3 is pushed down as shown in FIG. 4, the lower ends 33a of the insertion locking portions 33, 33 are flat bottoms as shown in the explanatory view of FIG. It is localized in a shape fitted into the surface 24. The displacement prevention hypotenuse 23 has an ascending slope with a large inclination angle from the flat bottom surface 24, and has a large frictional resistance to prevent displacement of the insertion locking portions 33, 33 into a reduced state, that is, displacement to FIG. 7A. To do.

  FIG. 7D shows the operation of the dropout prevention means 2 shown in FIG. That is, the displacement prevention hypotenuse 23 is set to the hypotenuse connecting the lower end 21 a of the inner short side 21 and the lower end 22 a of the outer long side 22. In this embodiment, since there is no flat bottom surface 24, the lower end 33 a of the insertion locking portions 33, 33 is positioned in a state of riding on the lower portion 23 a of the displacement prevention hypotenuse 23. Accordingly, the point load acts intensively on the inner side of the lower end 33a of the insertion locking portions 33, 33, and the frictional resistance is further increased, and the displacement of the insertion locking portions 33, 33 to the reduced state is strongly prevented. Is done.
