Benefits of technology
The present invention provides a method and structures for a low profile frictional slide mechanism for information technology equipment. The mechanism is designed to have minimal negative effects and overcome problems of previous arrangements. The mechanism includes predefined selected materials for the different parts to prevent galling and have rigidity and strength. The rail sections have wings to reduce rotation of the drawer and prevent rail locking when moved inwardly. Overall, this invention provides a more efficient and reliable mechanism for low-profile sliding in information technology equipment.
Problems solved by technology
Due to the high planar density requirements in information technology equipment, such as known server systems by International Business Machines Corporation of Armonk, N.Y., there is limited space available to place all required features and card components on a base planar.
Due to design requirements limited vertical space is available for a low-profile sliding drawer used in information technology equipment (ITE), computer or server system.
For example, limited vertical space is available for the low-profile sliding drawer used for a storage expansion drawer with an extendable direct access storage device (DASD) cage or drawer.
Due to design requirements a vertical slide mechanism can not be incorporated into such a storage expansion drawer.
Previous slide rail designs have had problems, for example, with metal particulate and other contaminates both interfering with the slide motion and contaminating electronics in the downstream airflow.

A method and structures are provided for implementing a low profile sliding drawer used in information technology equipment (ITE). A low-profile slide mechanism having a substantially horizontal cross section telescopes outwardly a predefined length and includes a plurality of rail sections that are interconnected with shouldered T pins, with sliding of the rail sections occurring on the T pin shoulders spacing apart the rail sections from an associated base pan and drawer. Each of the rail sections is movable a set amount of an overall length of the slide mechanism. The low-profile slide mechanism is friction based and includes different predefined selected materials forming the shouldered T pins and the rail sections to prevent galling and having predefined rigidity and strength.
Description
FIELD OF THE INVENTION[0001]The present invention relates generally to the data processing field, and more particularly, relates to a method and structures for implementing a low profile slide mechanism used in information technology equipment (ITE).DESCRIPTION OF THE RELATED ART[0002]High-density information technology equipment (ITE) advantageously is configured to meet the customer's processing and storage requirements. Various components are provided in high-density ITE, such as blade servers, manufactured by International Business Machines Corporation. Blade servers fit in a single chassis like books in a bookshelf and each is an independent server, with its own processors, memory, storage, network controllers, operating system and applications. The blade server simply slides into a bay in the chassis and plugs into a mid-plane or backplane, sharing power, fans, switches, and ports with other blade servers.[0003]Due to the high planar density requirements in information technol...
