Description

[Detailed description of the invention] Single-column bookcases include self-supporting single-column bookcases that can stand on their own by having the lower ends of the shelf struts integrally fixed to a horizontal support member or horizontal stand, and those that have these components or There was a single-post bookshelf with low stability without a stand, but in the latter single-post bookshelf with low stability, both the upper and lower ends of the shelf support need to be firmly fixed to the ceiling and floor, respectively. Of course, even with the former self-supporting single-post bookshelf, if the shelf height is high, the stability is relatively low, so a horizontal connecting member was attached to the upper end of each shelf support with bolts and nuts. However, it is possible to prevent one or a small number of shelf supports from falling by supporting them with other shelf supports, but to prevent the entire single-post bookshelf from falling due to horizontal force such as an earthquake, The horizontal connecting member must be connected to pillars, beams, ceilings, etc. of the building, and the horizontal connecting member must be extended not only to the location where the single-post bookshelf is installed, but also beyond this location. Not only does this impair the appearance, but the connection between the horizontal connecting member and the building structure is complicated.

Furthermore, with single-post bookcases in which the upper end of the shelf support is connected to the pillars, beams, walls, etc. of the building via horizontal connection members, if the building vibrates due to an earthquake or strong wind, the vibration of the building is directly transmitted to the shelf support. There were cases where stored items fell from the shelves.

Furthermore, since the upper end of the shelf support did not protrude upward to the left beyond the mounting position of the uppermost shelf board, the horizontal connecting member came close to above the heads of passersby and users, giving them a feeling of oppression.

The present invention relates to an improvement of a single-column bookshelf that overcomes these difficulties, and the lower part of the shelf support is provided with support legs at the lower end that are oriented perpendicular to the shelf frontage surface.
In a single-column bookshelf connected by horizontal joints along the shelf frontage surface, the upper end of the shelf support, which protrudes further upward from the shelf top plate mounting position, is oriented in a direction perpendicular to the shelf frontage surface. With the U-shaped intermediate channel material, which is connected by a U-shaped channel material and has a receiving piece integrally fixed to the end thereof, oriented in the direction along the shelf frontage surface, the U-shaped channel material and the receiving piece are connected. It is characterized in that the U-shaped channel material and the U-shaped intermediate channel material are integrally connected by inserting and screwing bolts over the area. The object of the present invention is to provide a single-post bookshelf that can firmly and stably stand up on its own.

As described above, the present invention is a single-column bookcase in which the lower part of the shelf support, which has support legs oriented at right angles to the shelf frontage at the lower end, is connected by a horizontal joint material along the shelf frontage. In this case, the upper ends of the shelf supports that protrude further above the shelf top plate mounting position are connected with a U-shaped channel member oriented in a direction perpendicular to the shelf frontage surface, and a receiving piece is integrally fixed to the end. U did
With the U-shaped intermediate channel material oriented in the direction along the shelf frontage surface, a bolt is inserted and screwed across the U-shaped channel material and the receiving piece to connect the U-shaped channel material and the U-shaped channel material. Because it is integrally connected with the shaped intermediate channel material, it can resist horizontal force in any direction and stand reliably on its own, making it extremely stable. Because it can stand on its own regardless of the situation, it is completely unaffected by the vibrations of the building caused by earthquakes, strong winds, etc., and books can be stored securely.

In addition, in the present invention, both the channel material and the intermediate channel material that connect the shelf supports to each other are formed in a U-shape with the opening facing upward, and the bottom of the channel material is a smooth surface. It has a good appearance, and lighting electric wires can be conveniently wired in the recessed part of the channel material, and a fluorescent light or the like can be arranged at the bottom of the channel material to facilitate the smooth handling of books.

Moreover, in the present invention, since the members that connect the upper ends of the shelf supports in a continuous manner vertically and horizontally are both U-shaped channels, the receiving piece fixed to the end of the intermediate channel material is connected to the channel material with bolts. At this time, the bolt can be easily screwed and tightened by inserting the hand through the upper opening of the channel material.

Further, in the present invention, since the connecting member is connected to the upper end of the shelf support that protrudes above the position where the top plate of the shelf is attached, the appearance is excellent and a fluorescent light or a display board can be attached.

An embodiment of the present invention illustrated in the drawings of FIGS. 1 to 8 will be described below. Reference numeral 1 denotes a steel hollow column that is significantly longer than a normal shelf column and has a hollow rectangular cross section; A large number of elongated locking holes (not shown) are provided vertically at regular intervals in the center of the front and rear surfaces 1a of the support 1, and a horizontal support with approximately the same cross-sectional shape as the support 1 is provided at the lower end of the support 1.
