Abstract
Abstract Motherboards and cards (herein "boards") mounted in computer enclosures must be supported on X, Y and Z axes to resist shock and vibration. This requires that four edges of the board be supported. Because of the high cost of such boards their lengths are made as small as possible, and this dimension is the direction of insertion of the board. A guide is attached to the leading edge of the board having a depending foot which engages fasteners formed on the base of the chassis of the enclosure. Thus the inner edge of the board is supported along two axes. Two side edges of the board are held in tracks and the outer edge is held at the point of insertion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
A front edge guide for securing a board in an enclosure, the board having a leading edge formed with slots and channel engaging means and the enclosure having a base and leg engaging means on the base, said guide comprising a channel shaped to detachably engage the leading edge, first means cooperable with the channel engaging means to hold said channel attached to the board, legs depending from said channel, and third means on said legs shaped to engage the leg-engaging means to limit movement of said guide relative to the enclosure along Y and Z axes, said first means comprising a pair of vertical elements shaped and positioned to be received in the slots, the distance between said elements being greater than the distance between the slots, said guide being flexible so that said guide bends vertically to permit insertion of one said element in a slot and then another said element in another slot and then pushed inwardly to seat said elements in the slots and said channel gripping the leading edge.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
38 words
A guide according to claim 1 in which the leg engaging means include fasteners on the base and in which said third means comprises forward extending feet on the lower ends of said legs fitting under the fasteners.
Claim 4
Dependent Claim
192 words
In combination a board having a leading edge and channel engaging means, and an enclosure having a base, a panel upstanding from said base formed with an opening into which said board fits, and leg engaging means on said base, and a guide, said guide comprising a channel shaped to detachably engage said leading edge, first means cooperable with said channel engaging means to hold said channel attached to said board, legs depending from said channel, and third means on said legs shaped to engage said leg engaging means to limit movement of said guide relative to said base along Y and Z axes, said first means comprising a pair of vertical elements and said channel engaging means being formed with slots in said leading edge to receive said elements, the distance between said elements being greater than the distance between said slots, said guide being flexible so that said guide may bend vertically to permit insertion of one said element in one said slot and then another said element in another said slot and then pushed inward to seat said elements in said slots and said channel gripping said leading edge.
Claim 5
Dependent Claim
192 words
In combination a board having a leading edge and channel engaging means, and an enclosure having a base, a panel upstanding from said base formed with an opening into which said board fits, and leg engaging means on said base, and a guide, said guide comprising a channel shaped to detachably engage said leading edge, first means cooperable with said channel engaging means to hold said channel attached to said board, legs depending from said channel, and third means on said legs shaped to engage said leg engaging means to limit movement of said guide relative to said base along Y and Z axes, said first means comprising a pair of vertical elements and said channel engaging means being formed with slots in said leading edge to receive said elements, the distance between said elements being greater than the distance between said slots, said guide being flexible so that said guide may bend vertically to permit insertion of one said element in one said slot and then another said element in another said slot and then pushed inward to seat said elements in said slots and said channel gripping said leading edge.
