Abstract
Abstract A pair of engine side shield structures are provided at the opposite sides of a vehicle engine and are supported on the frame of the vehicle. Each side shield structure includes a fixed baffle plate section, and upper and lower access doors which overlap the baffle section. The upper and lower doors are pivotally connected along lower edges thereof for swingable movement between respective closed positions wherein the panels are disposed vertically, one above the other, so as to block access to the inside of the engine compartment, and open positions wherein they are displaced angularly from their closed positions so as to permit access to the inside of the engine compartment. Integral with the lower door is an operator support structure which is located in the engine compartment when the lower door is in its closed position and which is located alongside the vehicle frame and projects outwardly therefrom to provide an operator support when the lower door is in its open position. Associated with the first door is a latch mechanism which can be padlocked in place so as to prevent unauthorized opening of the engine compartment, a further latch mechanism being associated with the second door and located such that it is entirely inside the engine compartment when the upper and lower doors are in their closed positions. A third latch mechanism is associated with the lower door and must be released before the first door can be opened to provide access to the latch mechanism associated with the second door.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
340 words
In an industrial vehicle of a type including a longitudinal frame supported on rotatable ground-engaging means, an engine mounted on the frame and located in an engine compartment bounded at top and upper side portions by a hood, at bottom and lower side portions by said frame and at opposite intermediate side portions by a pair of side shield structures extending between said frame and said hood, the improvement comprising: at least one of the side shield structures including a longitudinal upright door support means fixed to said frame and extending upwardly alongside said engine between the frame and hood; said support means including a baffle plate having upper and lower horizontal longitudinally extending edges respectively spaced below and above said hood and frame and inwardly from a bend line located substantially halfway between and extending parallel to said upper and lower edges; a first longitudinal door normally located in a closed position wherein it is vertically disposed beside and outwardly of a lower portion of said baffle plate and cooperate therewith to form a downwardly and inwardly directed passage leading to the engine compartment, said first door being pivotally mounted, adjacent to lower edge thereof, to said door support means for vertical swinging movement about a first horizontal, longitudinal axis from said closed position to an open position; a second longitudinal door normally located in a closed position wherein it is vertically disposed beside and outwardly of an upper portion of said baffle plate including said upper edge and cooperates therewith to define an upwardly and inwardly directed passage leading to the engine compartment; and said second door being pivotally mounted, adjacent a lower edge thereof, to said door support means for vertical swinging movement about a second horizontal, longitudinal axis from said closed position to an open position; latching means for releasably latching said first and second doors in their closed positions; and said first and second doors cooperating with said baffle plate to block manual access to the compartment when said doors are in their closed positions.
Claim 2
Dependent Claim
340 words
In an industrial vehicle of a type including a longitudinal frame supported on rotatable ground-engaging means, an engine mounted on the frame and located in an engine compartment bounded at top and upper side portions by a hood, at bottom and lower side portions by said frame and at opposite intermediate side portions by a pair of side shield structures extending between said frame and said hood, the improvement comprising: at least one of the side shield structures including a longitudinal upright door support means fixed to said frame and extending upwardly alongside said engine between the frame and hood; said support means including a baffle plate having upper and lower horizontal longitudinally extending edges respectively spaced below and above said hood and frame and inwardly from a bend line located substantially halfway between and extending parallel to said upper and lower edges; a first longitudinal door normally located in a closed position wherein it is vertically disposed beside and outwardly of a lower portion of said baffle plate and cooperate therewith to form a downwardly and inwardly directed passage leading to the engine compartment, said first door being pivotally mounted, adjacent to lower edge thereof, to said door support means for vertical swinging movement about a first horizontal, longitudinal axis from said closed position to an open position; a second longitudinal door normally located in a closed position wherein it is vertically disposed beside and outwardly of an upper portion of said baffle plate including said upper edge and cooperates therewith to define an upwardly and inwardly directed passage leading to the engine compartment; and said second door being pivotally mounted, adjacent a lower edge thereof, to said door support means for vertical swinging movement about a second horizontal, longitudinal axis from said closed position to an open position; latching means for releasably latching said first and second doors in their closed positions; and said first and second doors cooperating with said baffle plate to block manual access to the compartment when said doors are in their closed positions.
Claim 3
Dependent Claim
233 words
The industrial vehicle defined in claim 1 wherein said ground-engaging means includes upwardly extending inner surface means located beside and spaced outwardly from only a part of the one side shield structure, as considered in the longitudinal dimension of the latter; said first door extending substantially the entire length of the one side shield structure, as considered in the longitudinal dimension of the latter; and including a first and second longitudinally adjacent portions respectively extending coextensive with and being longitudinally displaced from the inner surface means of said ground-engaging means; said first and second portions respectively having heights, as considered with the first door in its closed position, which are less than and greater than the distance that the inner surface means is spaced from the one side shield structure and an operator support structure being integral with the first door and including a first and second support means respectively integral with said first and second portions of said first door and disposed so as to be located within said engine compartment when the first door is closed and so as to project outwardly horizontally when the first door is open; and said first support means being located so as to extend longitudinally between the engine compartment and ground-engaging means, when the first door is open, at a level above said second support means, the latter being located longitudinally of said ground-engaging means.
Claim 4
Dependent Claim
40 words
The vehicle defined in claim 2 wherein the baffle plate has a first end spaced from one end of the one side shield structure and said second portion of said first plate overlaps said first end of the baffle plate.
