Abstract

Abstract An inner seal boot, outer support boot cover, and bezel frame arrangement for enclosing the gap between the movable shift lever and an opening through which the lever of a vehicle transmission passes. The one-piece rubber boot cover has an upper conical-shaped sheath portion, an intermediate frusto-conical shaped flexible bellows portion, and a lower composite laminated base portion sealing enclosing a substrate core of thin sheet metal. The bellows portion has its lowermost convolute terminating in a groove defined in part by the substrate core with the groove dimensioned for releasable locking engagement of the bezel frame rectangular opening.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 364 words
In an outer boot cover and bezel frame assembly for a floor mounted manually operated vehicle transmission pivotal gear shift lever extending upwardly from an opening in a generally horizontal floor portion, wherein an improved attaching arrangement for said assembly comprising: a one-piece outer boot cover molded of elastomeric material having an upper flexible conical-shaped sheath portion tapering upwardly to a circular shift lever circular passage, an intermediate generally frusto-conical shaped flexible bellows portion formed with a plurality of convolutions having a generally rectangular shape in horizontal plan, each said bellows portion convolution having a generally rectangular outline in horizontal plan, and a lower composite laminated rigid base portion defined by a substrate core of sheet metal; said composite rigid base portion in the shape of an upstanding collar interconnecting a lower outwardly projecting foot flange adapted to be secured to said floor portion and an upper inwardly projecting rigid stop flange, said stop flange having interior opposed longitudinal and transverse edges defining a rectangular shaped opening having a predetermined length and width; said bellows portion having a series of flexible convolutions defined by alternating outer crests and inner troughs with the lower most crest terminating in a locking groove having a trough defined by planar upstanding flexible bight wall, said bight wall extending upwardly from said composite stop flange to its adjacent lower most convolute defining a predetermined groove height substantially equal to but slightly greater than the thickness of said bezel frame, with said bight wall having a rectangular exterior periphery determined by said rigid base portion stop flange rectangular shaped opening; said bezel frame having a rectangular shape in plan and formed with a central rectangular shaped aperture having a predetermined length and width substantially equal to but slightly greater than the length and width, respectively, of said base portion central rectangular opening, whereby with said bezel frame central opening receiving said shift lever and boot cover therethrough such that said lowermost of bellows convolution outer crest portion being resiliently deformed inwardly enabling said bezel frame to be moved downwardly until said bezel frame being seated on said base portion stop flange with its rectangular opening releasably engaging said locking groove.
Claim 2
Dependent Claim 364 words
In an outer boot cover and bezel frame assembly for a floor mounted manually operated vehicle transmission pivotal gear shift lever extending upwardly from an opening in a generally horizontal floor portion, wherein an improved attaching arrangement for said assembly comprising: a one-piece outer boot cover molded of elastomeric material having an upper flexible conical-shaped sheath portion tapering upwardly to a circular shift lever circular passage, an intermediate generally frusto-conical shaped flexible bellows portion formed with a plurality of convolutions having a generally rectangular shape in horizontal plan, each said bellows portion convolution having a generally rectangular outline in horizontal plan, and a lower composite laminated rigid base portion defined by a substrate core of sheet metal; said composite rigid base portion in the shape of an upstanding collar interconnecting a lower outwardly projecting foot flange adapted to be secured to said floor portion and an upper inwardly projecting rigid stop flange, said stop flange having interior opposed longitudinal and transverse edges defining a rectangular shaped opening having a predetermined length and width; said bellows portion having a series of flexible convolutions defined by alternating outer crests and inner troughs with the lower most crest terminating in a locking groove having a trough defined by planar upstanding flexible bight wall, said bight wall extending upwardly from said composite stop flange to its adjacent lower most convolute defining a predetermined groove height substantially equal to but slightly greater than the thickness of said bezel frame, with said bight wall having a rectangular exterior periphery determined by said rigid base portion stop flange rectangular shaped opening; said bezel frame having a rectangular shape in plan and formed with a central rectangular shaped aperture having a predetermined length and width substantially equal to but slightly greater than the length and width, respectively, of said base portion central rectangular opening, whereby with said bezel frame central opening receiving said shift lever and boot cover therethrough such that said lowermost of bellows convolution outer crest portion being resiliently deformed inwardly enabling said bezel frame to be moved downwardly until said bezel frame being seated on said base portion stop flange with its rectangular opening releasably engaging said locking groove.
Claim 3
Dependent Claim 107 words
The outer boot cover and bezel frame attaching arrangement as set forth in claim 1, wherein said bezel frame periphery formed with a downwardly projecting lip flange located a predetermined vertical distance above said floor portion with said bezel frame supported on said stop flange, carpeting overlying said floor portion having a rectangular opening conforming to the periphery of said foot flange, said carpeting having a predetermined thickness greater than said lip flange predetermined distance above said floor portion located on said floor portion, whereby upon said bezel frame engaged in said locking groove said carpeting being releasably captured between said lip flange and said floor portion.
Claim 4
Dependent Claim 56 words
The outer boot cover and bezel frame attaching arrangement as set forth in claim 1, wherein said lower most convolute crest portion extends laterally outwardly a predetermined dimension beyond said transition wall at least equal to twice the width dimension of said stop flange so as to releasably engage said bezel frame in said locking groove.
Claim 5
Dependent Claim 28 words
The outer boot cover and bezel frame attaching arrangement as set forth in claim 1, wherein an inner seal boot is provided for sealing covering said floor opening.
