Stepless shelf adjusting structure for rack

Abstract

A stepless shelf structure for rack includes a main post having a longitudinal and forward opened and reduced slide way; a plurality of sliding members movably connected to the slide way for connecting to a shelf each. Each of the sliding members includes a rearward slide block having an expanded rear portion for slidably receiving in the forward reduced slide way. A locating recess is formed at a lower side of each slide block to receive a transverse locating body. An adjusting lever is forward extended from the locating body for controlling the locating body to press or not press against two lateral outer wall surfaces of the forward reduced opening of the slide way. When the locating body is controlled not to press against the outer wall surfaces of the slide way, the shelf connected to the slide member may be adjusted to a different height.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an adjusting structure for rack, and more particularly to an adjusting structure for rack that allows stepless adjustment of a shelf and ensures stable locating of the shelf when the same bears an increased load.BACKGROUND OF THE INVENTION[0002]Most conventional racks have shelves that are fixedly mounted on the racks and can not be adjusted in height. Therefore, a user could not adjust the shelves to different heights on the racks according to actual needs or depending on different shapes and volumes of articles to be laid on the shelves. Therefore, the conventional racks are not convenient for use and a lot of spaces thereof are wasted. There has been developed a stepless adjustable rack, which allows a user to adjust the shelves to different heights according to actual needs, so as to effectively utilize every space on the rack. The conventional stepless adjustable rack mainly includes at least one main post, a pluralit...

Benefits of technology

[0006]A primary object of the present invention is to provide a stepless shelf adjusting structure for rack, so that any shelf of a rack may be freely adjusted to any desired height on a main post.

[0007]Another object of the present invention is to provide a stepless shelf adjusting structure for rack, which allows a shelf connected to the rack via the adjusting structure to bear an increased load without becoming unstable.

[0008]To achieve the above and other objects, the stepless shelf adjusting structure for rack according to a preferred embodiment of the present invention includes a main post having a longitudinally extended and forward opened and reduced slide way; and a plurality of sliding members movably connected at a rear end to the slide way and firmly connected at a front end to a shelf each. Each of the sliding members includes a rearward extended slide block having an expanded rear portion for slidably receiving in the forward reduced slide way. A locating recess is formed at a lower side of each slide block to receive a transverse locating body of a locating element. An adjusting lever of the locating element is forward extended from the locating body for controlling the locating body to press or not press against two lateral outer wall surfaces of the forward reduced opening of the slide way. When the locating body is controlled not to press against the outer wall surfaces of the slide way, the sliding member and accordingly, the shelf connected to that sliding member may be displaced and adjusted to a different height. And, when the locating body is controlled to press against the outer wall surfaces of the slide way, the shelf connected to the main post via the sliding member may be firmly located on the main post to bear an increased load without becoming unstable.

Problems solved by technology

Most conventional racks have shelves that are fixedly mounted on the racks and can not be adjusted in height.

Therefore, a user could not adjust the shelves to different heights on the racks according to actual needs or depending on different shapes and volumes of articles to be laid on the shelves.

Therefore, the conventional racks are not convenient for use and a lot of spaces thereof are wasted.

In the above described conventional stepless adjustable rack, while the automatic pressing of the cut edge of the support bracket against the inner wall surface of the dovetail groove allows stepless height adjustment of the support bracket, it does not allow the support bracket to bear a large load.

As a result, things positioned on the shelf supported on the support bracket are subject to the risk of falling and becoming damaged, and the conventional stepless adjustable rack is not practical for use.
