Abstract

Abstract An apparatus for reducing the aerodynamic drag of a refrigerated trailer of the type having a front wall and a refrigeration unit on the front wall. The apparatus comprises a wind deflector configured to reduce the aerodynamic drag of the refrigerated trailer. The wind deflector is attached to the refrigeration unit for movement between a drag-reducing position and an access position in which the wind deflector is displaced from the drag-reducing position to provide improved access to the refrigeration unit.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 127 words
An apparatus for reducing the aerodynamic drag of a refrigerated cargo carrying vehicle of the type having a front wall and a refrigeration unit on said front wall, said apparatus comprising: a wind deflector for at least partially enclosing the refrigeration unit and configured to reduce the aerodynamic drag of the vehicle; and means for attaching the wind deflector to the refrigeration unit for movement between a drag reducing position in which the wind deflector at least partially encloses the refrigeration unit to reduce the aerodynamic drag of the vehicle when the vehicle is moving forward whereby access to the refrigeration unit is limited and an access position in which the wind deflector is displaced from the drag-reducing position to provide increased access to the refrigeration unit.
Claim 2
Independent Claim 127 words
An apparatus for reducing the aerodynamic drag of a refrigerated cargo carrying vehicle of the type having a front wall and a refrigeration unit on said front wall, said apparatus comprising: a wind deflector for at least partially enclosing the refrigeration unit and configured to reduce the aerodynamic drag of the vehicle; and means for attaching the wind deflector to the refrigeration unit for movement between a drag reducing position in which the wind deflector at least partially encloses the refrigeration unit to reduce the aerodynamic drag of the vehicle when the vehicle is moving forward whereby access to the refrigeration unit is limited and an access position in which the wind deflector is displaced from the drag-reducing position to provide increased access to the refrigeration unit.
Claim 3
Dependent Claim 20 words
An apparatus as defined in claim 1 wherein the wind deflector is spaced from the vehicle in the drag-reducing position.
Claim 4
Dependent Claim 34 words
An apparatus as defined in claim 1 wherein said attaching means attaches the wind deflector solely to the refrigeration unit and the wind deflector is unattached to the vehicle except via the refrigeration unit.
Claim 5
Dependent Claim 36 words
An apparatus as defined in claim 1 wherein the refrigeration unit has control means and the wind deflector has a removed region through which access can be had to the control means in the drag-reducing position.
Claim 6
Dependent Claim 43 words
An apparatus as defined in claim 4 wherein said wind deflector includes a generally forwardly facing wind deflecting wall and the removed region is in said wall adjacent a lower edge and adjacent a side edge of said wall in the drag-reducing position.
Claim 7
Dependent Claim 33 words
An apparatus as defined in claim 1 wherein the vehicle has at least one handhold and the wind deflector has a recess to at least partially accommodate the handhold in the drag-reducing position.
Claim 8
Dependent Claim 51 words
An apparatus as defined in claim 1 wherein the wind deflector has a curved forwardly facing wind deflecting wall, said curved forwardly facing wind deflecting wall having an opening to provide air to the refrigeration unit and otherwise being continuous and devoid of openings for providing access to the refrigeration unit.
Claim 9
Dependent Claim 30 words
An apparatus as defined in claim 1 wherein said attaching means mounts the wind deflector on the refrigeration unit for pivotal movement between said drag-reducing position and said access position.
Claim 10
Dependent Claim 28 words
An apparatus as defined in claim 8 including locking means on the refrigeration unit and on said wind deflector for holding the wind deflector in the drag-reducing position.
Claim 11
Dependent Claim 68 words
An apparatus as defined in claim 9 wherein said wind deflector has upper and lower edge portions in said drag-reducing position, said wind deflector pivots between said positions thereof about a pivot axis located adjacent said upper edge portion, said locking means being coupled to said wind deflector adjacent said lower edge, and sealing means between said lower edge portion and said refrigeration unit in said drag-reducing position.
Claim 12
Dependent Claim 34 words
An apparatus as defined in claim 9 wherein said attaching means attaches the wind deflector solely to the refrigeration unit and the wind deflector is unattached to the vehicle except via the refrigeration unit.
Claim 13
Dependent Claim 79 words
An apparatus as defined in claim 11 wherein said wind deflector is spaced from the vehicle in the drag-reducing position, the refrigeration unit has control means, the wind deflector has a curved forwardly facing wind deflecting wall having a single opening therein to provide air to the refrigeration unit, said wind deflector having a removed region adjacent a lower edge thereof in the drag-reducing position through which access can be had to the control means in the drag-reducing position.
Claim 14
Independent Claim 104 words
An apparatus for reducing the aerodynamic drag of a refrigerated cargo carrying vehicle of the type having a front wall and a refrigeration unit on said front wall, said apparatus comprising: a wind deflector for at least partially enclosing the refrigeration unit and configured to reduce the aerodynamic drag of the vehicle; and means for attaching the wind deflector solely to the refrigeration unit with the wind deflector at least partially enclosing the refrigeration unit to reduce the aerodynamic drag of the refrigerated vehicle when the vehicle is moving forward whereby the wind deflector is unattached to the vehicle except via the refrigeration unit.
Claim 15
Independent Claim 104 words
An apparatus for reducing the aerodynamic drag of a refrigerated cargo carrying vehicle of the type having a front wall and a refrigeration unit on said front wall, said apparatus comprising: a wind deflector for at least partially enclosing the refrigeration unit and configured to reduce the aerodynamic drag of the vehicle; and means for attaching the wind deflector solely to the refrigeration unit with the wind deflector at least partially enclosing the refrigeration unit to reduce the aerodynamic drag of the refrigerated vehicle when the vehicle is moving forward whereby the wind deflector is unattached to the vehicle except via the refrigeration unit.
Claim 16
Dependent Claim 18 words
An apparatus as defined in claim 13 wherein the wind deflector is out of contact with the vehicle.
Claim 17
Dependent Claim 32 words
An apparatus as defined in claim 13 wherein the refrigeration unit has control means and the wind deflector has a removed region through which access can be had to the control means.
Claim 18
Dependent Claim 39 words
An apparatus as defined in claim 15 wherein said wind deflector includes a generally forwardly facing wind deflecting wall and the removed region is in said wall adjacent a lower edge and adjacent a side edge of said wall.
Claim 19
Dependent Claim 33 words
An apparatus as defined in claim 13 wherein the vehicle has at least one handhold and the wind deflector has a recess to at least partially accommodate the handhold in the drag-reducing position.
Claim 20
Dependent Claim 48 words
An apparatus as defined in claim 13 wherein the wind deflector has a curved forwardly facing wind deflecting wall, said curved forwardly facing wind deflecting wall has an opening to provide air to the refrigeration unit, and said wind deflector has a top opening and a bottom opening.
Claim 21
Dependent Claim 56 words
An apparatus as defined in claim 8 wherein the wind deflector has at least one notch in the lower edge thereof which exposes a region of the refrigeration unit and said apparatus includes locking means coupled to said region and said wind deflector adjacent said notch for releasably locking the wind deflector in the drag-reducing position.
Claim 22
Dependent Claim 20 words
