Description
- The invention relates to a component retention mechanism, and more particularly to a component retention mechanism for mounting and locking computer hardware components in place within a computer hardware rack structure.
- The computer hardware rack structure is a known structure for housing commercial grade computer hardware components. These rack structures contain different apertures, cavities, slots, and corresponding mounting mechanisms for supporting and locking in place the different computer hardware components.
- Where there is a demand for multiple computer components in compact areas, computer hardware rack structures often provide for slidably mounting components. Each component typically is attached to a tray, and the tray is positioned in the rack where it is able to captively slide. If a user needs to gain access to a particular component, the tray is slid out of the component rack, providing the desired access. Once the user is finished with the component, the tray is slid back into the component rack. Often threaded fasteners (such as, e.g., screws) secure the tray to the rack in a closed position.
- However, the computer hardware rack structure, in some instances, may become undesirably crowded with the various computer hardware components. Thus, it is difficult to install and remove components from within the rack structure. In some cases, a user is limited to using a single hand to install or remove a component because of the configuration of the rack structure. It can be even more difficult to manage the insertion and removal of the threaded fasteners that secure the trays in place. There is, in most instances, not an option to leave the components un-fastened (i.e., not use threaded or other fasteners to secure the component in place) because during the operation of the system, shock or vibration can cause the component to unseat itself.
- There exists in the art a need for a component retention mechanism that enables a user to remove, install, and secure a component within a rack or base structure in a simple manner, without the use of difficult to manage fasteners. Aspects of the present invention embody further solutions in this art.
- A component retention mechanism, in accordance with one example embodiment of the present invention, has a bolt receiver mounted to a base structure into which the component to be installed mounts. The base structure can be, e.g., a computer hardware rack structure. A spring casing mounts to the component to be installed. A spring having a first end and a second end mounts within the spring casing. At least one locking bolt extends from one of the first and second ends of the spring, such that the locking bolt engages with the bolt receiver to retain the component in the base structure as desired.
- The component retention mechanism, according to one aspect of the present invention, has at least one lever extending from the spring enabling spring compression and corresponding manipulation of the locking bolt or bolts through each bolt receiver.
- The component retention mechanism, according to still another aspect of the present invention, has a first locking bolt extending from the first end of the spring and a second locking bolt extending from the second end of the spring. The component retention mechanism with this configuration further includes a first lever extending from the first end of the spring and a second lever extending from the second end of the spring. The first and second levers enable spring compression.
- The component retention mechanism, in accordance with another aspect of the present invention, includes the bolt receiver with a first support arm having a first ramp and a second support arm having a second ramp, the first and second ramps enabling engagement with the first and second locking bolts. The bolt receiver can include at least one support arm having a bevel tip for better receiving each of the locking bolts.
- A computer hardware rack structure, in accordance with one aspect of the present invention, includes at least one component retention mechanism for mounting and locking components in place within the rack structure. The component retention mechanism has a bolt receiver mounted to the rack structure, a spring casing mounting to the at least one component, a spring having a first end and a second end and mounted within the spring casing, and at least one locking bolt extending from one of the first and second ends of the spring. The locking bolt engages with the bolt receiver to retain the component in the rack structure.
- A method of mounting a component in a base structure according to one aspect of the present invention includes the steps of pinching at least one lever in a spring casing to compress at least one spring and retract at least one bolt. The method further includes placing the component having the spring casing mounted thereto into the base structure. The method concludes with releasing the at least one lever in the spring casing to expand the spring and extend the at least one locking bolt to engage with a bolt receiver, locking the component in place.
- The method can further include a pinching step wherein the step comprises pinching two levers to compress two springs and retract two locking bolts. The method continues with the releasing step comprising releasing the two levers to expand the two springs and extend the two locking bolts to engage with the bolt receiver.
