[0001]

[Industrial applications]

 The present invention relates to a shelf including a mounting portion for a column and a shelf body.

[0002]

[Prior art]

 Conventionally, as a shelf as described above, the mounting portion and the shelf body are welded, or the mounting portion 9 has a triangular plate-shaped upper wall portion 11 and two ends of the upper wall portion 11 as shown in FIG. There has been one in which a pair of side wall portions 13 extending downward from the edge is formed, and the side wall portions 13 and the shelf main body 10 formed of a plate material are connected using a mounting tool such as a bolt 21 or a rivet.

[0003]

[Problems to be solved by the device]

 However, with the above-described configuration, welding work or mounting work such as bolt tightening is performed using a dedicated device such as a welding machine or a dedicated tool such as a spanner. As a result, the work of connecting the mounting portion and the shelf body was inefficient.

An object of the present invention is to improve the work efficiency of the connecting work between the mounting portion and the shelf body.

[0005]

[Means for Solving the Problems]

 A shelf according to the present invention comprises a mounting portion for a column and a shelf main body, and a first characteristic configuration is that the mounting portion and the shelf main body are engaged with each other to connect them. Engaging portions are formed, and at least one of the engaging portions retracts due to the mutual abutment due to their approach movement to allow the engagement, and is urged to return to the engaged state side. It is composed of an elastic engagement type.

A second characteristic configuration is that the mounting portion includes a triangular plate-shaped upper wall portion and a pair of side wall portions extending downward from two end edges of the upper wall portion. The mating portion is formed by forming a projection-shaped or hole-shaped fitting portion on each of the pair of side wall portions, and the shelf body is formed of a plate material, and the engagement portion of the shelf body is In a pair of elastic tongues integrally formed so as to enter between the pair of side wall portions in the engaged state, contact the side wall portion, and project from the shelf body to the mounting portion side. The elastic engagement type is formed by forming a hole-shaped or protrusion-shaped fitting portion that fits in the fitting portion on the mounting portion side.

A third characteristic configuration is that one of the mounting portion and the shelf main body is elastically deformed to contact with the contacted contacting portion on the other side in the engagement state to connect with the mounting portion. An elastic body for urging the separation body for urging the shelf body toward the separation side is provided.

In a fourth characteristic configuration, the elastic body is configured to urge along a direction along a shelf mounting surface, and the shelf between the attachment portion and the shelf body by the urging force of the elastic body. A guide part is formed on the mounting part and the shelf body so as to contact the mounting part and the shelf body so that the mounting part and the shelf body move closer to each other along with the relative movement along the mounting surface. is there.

[0009]

[Action]

 According to the first characteristic configuration of the present invention, the mounting portion and the shelf body are connected by moving them toward each other and engaging the engaging portions with each other.

According to the second characteristic configuration of the present invention, the mounting portion and the shelf body are moved closer to each other so that the fitting portion formed on the side wall portion of the mounting portion and the elastic tongue formed on the shelf body. The connection is made by fitting the formed fitting portion.

According to the third characteristic configuration of the present invention, when the attachment portion and the shelf main body are connected by being moved closer to each other against the urging force of the elastic body to the distant side, the urging force of the elastic body on the distant side is used. Even if there is looseness in the engagement state between the engaging portions, the engagement state can be made stable.

According to the fourth characteristic configuration of the present invention, when the mounting portion and the shelf main body are moved close to each other against the biasing force of the elastic body and connected, the mounting portion and the shelf main body are separated by the biasing force of the elastic body. Along with the relative movement in the direction along the shelf mounting surface, the guide portion guides the guide portion so that the mounting portion and the shelf main body are moved closer to each other in the vertical direction, and the mounting portion and the shelf main body are moved in the vertical direction. Can be closely attached.

[0013]

[Effect of device]

 According to the first characteristic configuration of the present invention, the mounting portion and the shelf body can be connected by simply moving the engaging portions toward each other and engaging them without using a mounting bracket or a dedicated tool. Since it is possible to improve the work efficiency of the connection work between the mounting part and the shelf body.

According to the second characteristic configuration of the present invention, the engaging portion is configured while effectively utilizing the configuration of the mounting portion for robust construction and the original configuration of the shelf main body made of the plate material. By doing so, we were able to improve the work efficiency of the connection work while maintaining a sturdy structure.

According to the third characteristic configuration of the present invention, it is possible to suppress the rattling that occurs due to the engagement type connection due to the urging force of the elastic body. Therefore, while improving the connection work efficiency. However, I decided to get a shelf without rattling.

According to the fourth characteristic configuration of the present invention, by utilizing the rattling that occurs because of the engagement type, the mounting portion and the shelf body are brought into close contact with each other in the vertical direction as much as possible, and the shelf mounting that can be easily seen by the user is displayed. I was able to make the surface beautiful.
