Abstract
Abstract A desk having a desk top defining a work surface, an adjoining upright wall panel along at least one edge of the desk top, and an electrical cord transition assembly for a slot in the at least one edge of the desk top, at the juncture between the desk top and wall panel. The transition assembly includes a grommet which snugly lines the slot, and a grommet cover which is pivotally attached to the slot via a substantially vertically oriented pivot axis. The grommet cover may be easily assembled with the grommet, even when the grommet is individually preassembled with the slot, but difficult to remove without removing the assembly from the slot. Cooperative elements of the grommet and grommet cover form a tactile detent when the grommet cover is in a position which closes the grommet and associated slot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
127 words
In a desk having a desk top defining a work surface, and an adjoining upright wall panel at a predetermined edge of the desk top, an electrical cord transition assembly for accommodating an electrical plug of an electrically energizable object on the work surface which requires access to an electrical receptacle below the work surface, comprising: an inwardly extending slot defined by the predetermined edge of the desk top, a grommet lining said slot, and a grommet cover pivotally attached to said grommet via a substantially vertically oriented pivot axis, whereby the grommet cover substantially covers the slot in a predetermined first position, and may be pivoted away from said first position to a temporary second position which exposes the slot for passage of an electrical plug.
Claim 2
Dependent Claim
127 words
In a desk having a desk top defining a work surface, and an adjoining upright wall panel at a predetermined edge of the desk top, an electrical cord transition assembly for accommodating an electrical plug of an electrically energizable object on the work surface which requires access to an electrical receptacle below the work surface, comprising: an inwardly extending slot defined by the predetermined edge of the desk top, a grommet lining said slot, and a grommet cover pivotally attached to said grommet via a substantially vertically oriented pivot axis, whereby the grommet cover substantially covers the slot in a predetermined first position, and may be pivoted away from said first position to a temporary second position which exposes the slot for passage of an electrical plug.
Claim 3
Dependent Claim
57 words
The desk of claim 1 wherein at least a portion of the predetermined edge of the desk top is spaced from the wall panel by a dimension selected to enable a cord to be moved along the work surface after an electrical plug on the end of the cord has been inserted through the grommet lined slot.
Claim 4
Dependent Claim
53 words
The desk of claim 1 wherein the grommet cover is dimensioned such that when the grommet cover is in the closed position there is a predetermined dimension between the grommet cover and the wall panel, enabling the grommet cover to be pivoted away from the closed position without interference with the wall panel.
Claim 5
Dependent Claim
40 words
The desk of claim 1 including co-operable members on the grommet and grommet cover which define a detent which holds the grommet cover in the first position until a manually applied force applied to the grommet cover overcomes the detent.
Claim 6
Dependent Claim
80 words
The desk of claim 4 wherein the co-operable members include a depending resilient leg member on the grommet cover having an integral outwardly extending shoe, and first and second spaced members on the grommet oriented to provide a predetermined interference with said shoe as the grommet cover is pivoted and approaches the first position, said first and second spaced members holding said shoe between them when said interference is overcome as the grommet cover is pivoted to the first position.
Claim 7
Dependent Claim
116 words
The desk of claim 1 wherein the grommet cover includes a lower flat surface having a plurality of circumferentially spaced resilient locking fingers depending therefrom, each of said locking fingers having a predetermined outwardly extending hook a predetermined dimension from said lower flat surface, and wherein the grommet includes a tubular portion having upper and lower surfaces, said tubular portion defining an opening which extends between said upper and lower surfaces, said locking fingers of the grommet cover being disposed in the opening defined by said tubular member, with the outwardly extending hooks extending over a portion of the lower surface of the tubular portion, to hold the grommet cover in assembled relation with the grommet.
Claim 8
Dependent Claim
67 words
The desk of claim 6 wherein the opening defined by the tubular portion of the grommet is round, having a larger diameter at the upper surface than at the lower surface and a smoothly converging wall portion therebetween, with the diameter at the lower surface being selected to provide the locking action provided by the outwardly extending hooks on the depending locking fingers of the grommet cover.
Claim 9
Dependent Claim
75 words
The desk of claim 7 wherein the lower flat surface of the grommet cover includes a depending resilient leg member having a detent shoe extending outwardly therefrom, the lower surface of the tubular portion has two spaced members for receiving the detent shoe when the grommet cover is in the first position, and the smoothly converging wall portion includes a slot dimensioned to receive the shoe during assembly of the grommet cover with the grommet.
Claim 10
Dependent Claim
86 words
The desk of claim 1 wherein at least a portion of the predetermined edge of the desk top is spaced from the wall panel by a dimension selected to provide an elongated opening which enables an electrical cord to be moved along the work surface after an electrical plug on the end of the cord has been inserted through the grommet lined slot, and wherein the wall panel is incompressible to the extent that a three wire electrical plug cannot be inserted through said elongated opening.
Claim 11
Dependent Claim
48 words
The desk of claim 1 wherein the grommet has a wall portion which lines the slot, and including flanges on the wall portion which extend uniformly outward from edges which define the slot, on both the work surface side of the table top, and on the opposing side.
