Description

Rail member of sliding bookshelf

[0001] The present invention relates to a rail member of a sliding bookshelf, and more particularly, to a rail member of a sliding bookshelf that can easily adjust the horizontality of a rail member that guides the sliding of a sliding bookshelf, thereby ensuring the safety of the sliding bookshelf and preventing noise generation.

[0002] As is well known, a bookshelf is a device designed to hold or place documents or books, and is installed in places such as libraries or office storage rooms.

[0003] Recently, there has been a growing trend towards mobile bookshelves to efficiently store a large amount of material in a small space.

[0004] These mobile bookshelves are designed to increase storage space for records by installing bookshelves on rails laid on the floor of the bookshelf, allowing the bookshelves to be moved.

[0005] As prior art related to rails of a mobile bookshelf, Republic of Korea Utility Model Publication No. 20-2000-0008438 (publication date May 15, 2000), Republic of Korea Utility Model Registration No. 20-0188084 (registration date April 24, 2000), Republic of Korea Patent Registration No. 10-1424153 (registration date July 22, 2014), and Republic of Korea Patent Registration No. 10-0910397 (registration date July 27, 2009) are disclosed.

[0006] The above-described conventional technology has the technical gist of a movable bookshelf sliding along a rail installed on the floor.

[0007] However, the above-described conventional technology had a problem in that, when the floor is not level, the front-back and / or left-right horizontality of the rails installed on the floor could not be adjusted.

[0008] Rails that are not in a horizontal state like this can cause noise due to friction when the mobile bookshelf slides, and can cause the mobile bookshelf to tip over due to imbalance and movement, which can lead to injury to people using the mobile bookshelf.

[0009] The present invention has been devised to solve the conventional problems as described above, and an object of the present invention is to provide a rail member of a sliding bookshelf that can easily adjust the horizontality of a rail member that guides the sliding of a sliding bookshelf, thereby preventing noise generation during sliding of the sliding bookshelf and preventing overturning, thereby improving safety.

[0010] In order to achieve the above object, the present invention is a technical idea of ​​a rail member that guides left-right sliding of a rolling wheel provided at the bottom of a sliding bookshelf, comprising: a guide member disposed on the floor to guide left-right rolling of the rolling wheel; a front rail base having a front guide slit formed integrally to be connected to the front of the guide member and exposed along the front; a rear rail base having a rear guide slit formed integrally to be connected to the rear of the guide member and exposed along the rear; a sliding holder having a tap hole vertically penetrating toward the floor and slidably coupled to each of the front guide slit and the rear guide slit; and a balance bolt that is screwed into the tap hole of the sliding holder and comes into contact with the floor to adjust the horizontal balance of the front rail base and the rear rail base.

[0011] The present invention may further include a stopper formed on the exposed upper and lower ends of the front guide slit and the rear guide slit to prevent the front of the sliding holder from being detached.

[0012] The above sliding holder may include a sliding block that is slidably coupled along the front guide slit and the rear guide slit, and a holder block that is exposed through the interlocking rim and has the tap hole.

[0013] At this time, the holder block can be formed thinner than the thickness of the sliding block.

[0014] The above guide member, the front rail base, and the rear rail base can be integrally formed by extrusion molding of a metal material.

[0015] According to the present invention implemented with the above-described solution, a plurality of sliding holders arranged at predetermined intervals along the front guide slit and the rear guide slit are screwed with balance bolts to easily adjust the horizontal balance of the rail member, thereby preventing noise and overturning during sliding of the sliding bookshelf, thereby improving safety.
