Option board holder for use in a computer

Claim 2

An option board holding apparatus for use in a computer to accommodate a plurality of option boards which can be plugged into expansion slots to extend the computer's capability, said computer having a front chassis, said front chassis having an upper slot and a lower slot, said option board holding means comprising: an option board holding plate; a plurality of pairs of rail portions provided on the rear surface of said holding plate, each pair of said rails defining a channeled groove for slidably receiving and retaining one side vertical edge of an option board; upper downturned depending resilient latch means extending from said board holding plate in the direction opposite to the direction of said rail portions, said upper latch means having beveled reinforcing side sections for being slidably received in the upper slot; lower downturned depending resilient latch means extending from said board holding plate in the direction opposite to the direction of said rail portions, said lower latch means having beveled reinforcing side sections for being slidably received in the lower slot; and elongated resilient middle latch means provided on said holding plate for engaging the lower slot, the uppermost edge thereof for abutting against a corresponding upper periphery of said lower slot.

Claim 3

An option board holding apparatus according to claim 1, wherein said upper resilient latch means have cantilevered slits provided on the periphery thereof.

Claim 4

An option board holding apparatus according to claim 1, wherein each of said reinforcing sides of said upper and lower downturned depending resilient latch means has a beveled section for slidingly contacting with said slots.

Claim 5

An option board holding apparatus according to claim 1, wherein said elongated resilient middle latch means is cantilevered by slits provided on the periphery thereof.

Claim 6

An option board holding apparatus according to claim 4, wherein said uppermost free edge is extended from said front chassis in the opposite direction to said rail portions.

Claim 7

An option board holding apparatus according to claim 1, wherein each of said reinforcing sides of said upper and lower downturned depending resilient latch means has a beveled section for sliding contacting with said slots.

Claim 8

An option board holding apparatus for use in a computer to accommodate a plurality of option boards which can be plugged into expansion slots to extend the computer's capability, said computer having a front chassis, said front chassis having pairs of upper and lower slots, said option board holding means comprising: an option board holding plate: a plurality of pairs of rail portions provided on the rear surface of said holding plate, each pair of said rails defining a channeled groove for slidably receiving and retaining one side vertical edge of an option board; upper hooks, each upper hook formed from a square flap punched out from an upper part of said holding plate and comprises of a first portion connected to said plate and extending rearward therefrom and a second hook portion extending from said first portion substantially parallel to said plate for engaging with a lower periphery of a corresponding one of said upper slots, said first portion having at least a pair of slanted reinforcing side ribs extending parallel to each other; lower hooks extending rearward from the lower end of said holding plate, each lower hook having a first portion connected to said holding plate and a second hook portion extending from the first portion for engaging with the lower periphery of a corresponding one of said lower slots, said first portion having a pair of slanted reinforcing side ribs extending parallel to each other; and elongated resilient latch means having upper resilient faces provided on said holding plate for engaging with a corresponding one of said lower slots with the upper resilient faces thereof abutting against corresponding upper peripheries of said lower slots.

Claim 9

An option board holding apparatus for use in a computer to accommodate a plurality of option boards which can be plugged into expansion slots to extend the computer's capability, said computer having a front chassis, said front chassis having pairs of upper and lower slots, said option board holding means comprising: an option board holding plate: a plurality of pairs of rail portions provided on the rear surface of said holding plate, each pair of said rails defining a channeled groove for slidably receiving and retaining one side vertical edge of an option board; upper hooks, each upper hook formed from a square flap punched out from an upper part of said holding plate and comprises of a first portion connected to said plate and extending rearward therefrom and a second hook portion extending from said first portion substantially parallel to said plate for engaging with a lower periphery of a corresponding one of said upper slots, said first portion having at least a pair of slanted reinforcing side ribs extending parallel to each other; lower hooks extending rearward from the lower end of said holding plate, each lower hook having a first portion connected to said holding plate and a second hook portion extending from the first portion for engaging with the lower periphery of a corresponding one of said lower slots, said first portion having a pair of slanted reinforcing side ribs extending parallel to each other; and elongated resilient latch means having upper resilient faces provided on said holding plate for engaging with a corresponding one of said lower slots with the upper resilient faces thereof abutting against corresponding upper peripheries of said lower slots.
