Description

[Detailed description of the invention] Single-post shelves include self-supporting single-post shelves that can stand on their own by integrally fixing the lower end of the shelf support to a horizontal support member or horizontal stand, and two types of single-post shelves that can stand on their own by integrally fixing the lower end of the shelf support to a horizontal support member or horizontal stand. There was a single-post shelf with low stability without a base, but in the latter single-post shelf 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 column shelf, if the shelf is high, stability is relatively low, so a horizontal connecting member is attached to the upper end of each shelf support with bolts and nuts. In this case, one or a few of the many shelf supports can be prevented from falling by supporting them with other shelf supports, but in order to prevent the entire single-post shelf from falling due to horizontal force such as an earthquake, , the horizontal connecting member must be connected to pillars, walls, ceilings, etc. of the building, and the horizontal connecting member must be extended not only to the location where the single-post shelf is installed, but also beyond this location. This not only impairs the appearance but also complicates the connection between the horizontal connecting member and the building structure.

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.

Furthermore, with a single-post type shelf in which the upper end of the shelf support is connected to the building's pillar, wall, etc. via a horizontal connection member, if the building vibrates due to an earthquake or strong wind, the vibration of the building will be directly transmitted to the shelf support. There were cases where stored items fell from the shelves.

The present invention relates to an improvement of a single-layer, single-column bookshelf that overcomes these difficulties. In a single-layer, single-column bookshelf connected by horizontal horizontal joint members, the upper ends of the leg supports are connected by a U-shaped channel member oriented in a direction perpendicular to the shelf frontage surface, and A notch is provided on the upper edge of the side piece at the upper end of the support of the U-shaped channel material, and protrusions that engage with the notch are formed at both ends of the U-shaped intermediate channel material. A receiving piece is integrally fixed to the inner surface, and a protrusion of the U-shaped intermediate channel material oriented in a direction parallel to the horizontal joint member is engaged with a notch of the U-shaped channel material, and the U-shaped The U-shaped channel material and the U-shaped intermediate channel material are integrally connected by inserting and screwing one bolt between the channel material and the receiving piece, and its purpose and purpose are The point of this invention is to provide a single-layer, single-post type bookshelf that allows a group of single-post type shelves to firmly and stably stand on its own regardless of the building.

In the present invention, as described above, the upper ends of the shelf supports are not only connected by a U-shaped channel material oriented in a direction perpendicular to the shelf frontage surface, but also in a U-shaped channel material oriented in a direction along the shelf frontage surface. The end of the intermediate channel material and the U-shaped channel material are rigidly connected by a receiving piece and one bolt, so they can resist horizontal forces in any direction and reliably. It can stand on its own and has a high degree of stability, and the shelf support can stand on its own independent of the building.

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 screwing and fixing work of the bolt can be easily performed by inserting the hand through the upper opening of the channel material.

Further, in the present invention, a notch is provided at the upper end edge of the side part at the upper end position of the support of the U-shaped channel material, and protrusions that engage with the notch are formed at both ends of the U-shaped intermediate channel material. At the same time, the receiving piece is integrally fixed to the inner surface of the U-shaped intermediate channel.
In contrast to the U-shaped channel material described above, the U-shaped intermediate channel material does not become twisted or slanted even when screwed with a single bolt, and can be accurately and easily aligned to a predetermined position. Since only one bolt is required and the number of parts is small, assembly work can be carried out efficiently and assembly accuracy can be improved.

The embodiment shown in FIGS. 1 to 6 will be described below. Reference numeral 1 is a steel hollow column that has a hollow rectangular cross section and is significantly longer than an ordinary shelf column. A large number of elongated locking holes (not shown) are provided vertically at regular intervals, and a horizontal support leg 2 with approximately the same cross-sectional shape as the support support 1 is integrated with the support support 1 by welding or the like at the lower end of the support support 1. It is fixed in an inverted T shape.
