Vehicle door system and method of operation
A vehicle comprises a side wall shaped to define a door opening and a door-exclusion zone. The door-exclusion zone has a maximum height that is higher than a bottom edge of the door opening and lower than a top edge of the door opening. The vehicle also includes a rail joined to a major surface of the side wall, an arm assembly pivotably anchored at a first end thereof to the side wall, and a door having a closed-door position aligned with the door opening. A first portion of the door is slidably engaged with the rail and a second portion of the door is pivotably coupled to a second end of the arm assembly.
1. A vehicle comprising:
a. a side wall shaped to define a door opening and a door-exclusion zone, the door-exclusion zone comprising at least one of a wheel well, a cargo compartment and an air conditioner, the door-exclusion zone having a maximum height that is higher than a bottom edge of the door opening and lower than a top edge of the door opening;
b. a rail joined to a major surface of the side wall;
c. an arm assembly pivotably anchored at a first end thereof to the side wall; and
d. a door having a closed-door position aligned with the door opening, a first portion of the door being slidably engaged with the rail and a second portion of the door being pivotably coupled to a second end of the arm assembly, the arm assembly and the rail being arranged to constrain movement of the door between the closed-door position and an open-door position higher in its entirety than the door-exclusion zone in its entirety, to a travel-path that does not impinge upon the door-exclusion zone,
wherein the door movement constrained to the travel-path includes, in a door-opening mode, an upward vector and a longitudinal vector toward the door-exclusion zone, and in a door-closing mode, a downward vector and a longitudinal vector away from the door-exclusion zone.
2. A vehicle comprising:
a. a side wall shaped to define a door opening and a door-exclusion zone, the door-exclusion zone comprising at least one of a wheel well, a cargo compartment and an air conditioner, the door-exclusion zone having a maximum height that is higher than a bottom edge of the door opening and lower than a top edge of the door opening;
b. a rail joined to a major surface of the side wall;
c. an arm assembly pivotable anchored at a first end thereof to the side wall; and
d. a door having a closed-door position aligned with the door opening, a first portion of the door being slidably engaged with the rail and a second portion of the door being pivotably coupled to a second end of the arm assembly, the arm assembly and the rail being arranged to constrain movement of the door between the closed-door position and an open-door position higher in its entirety than the door-exclusion zone in tis entirety, to a travel-path that does not impinge upon the door-exclusion zone,
wherein the door opening is disposed between the door-exclusion zone and an end of the vehicle nearest the to the door-exclusion zone, and the door movement constrained to the travel-path includes, in a door-opening mode, a longitudinal vector away from the end of the vehicle nearest to the door-exclusion zone.
3. A vehicle comprising:
a. a side wall shaped to define a door opening and a door-exclusion zone, the door-exclusion zone comprising at least one of a wheel well, a cargo compartment and an air conditioner, the door-exclusion zone having a maximum height that is higher than a bottom edge of the door opening and lower than a top edge of the door opening;
b. a rail joined to a major surface of the side wall;
c. an arm assembly pivotable anchored at a first end thereof to the side wall; and
d. a door having a closed-door position aligned with the door opening, a first portion of the door being slidably engaged with the rail and a second portion of the door being pivotably coupled to a second end of the arm assembly, the arm assembly and the rail being arranged to constrain movement of the door between the closed-door position and an open-door position higher in its entirety than the door-exclusion zone in tis entirety, to a travel-path that does not impinge upon the door-exclusion zone,
wherein the side wall is formed to include a door pocket therewithin, the major surface is a major internal surface of the door pocket, and the arm assembly is pivotably anchored at a first end thereof within the door pocket.
4. The vehicle of claim 3 , wherein the travel-path is disposed entirely within a volume consisting of the doorframe and the door pocket.
5. A method of operating a vehicle, the vehicle comprising: (i) a side wall shaped to define a door opening and a door-exclusion zone comprising at least one of a wheel well, a cargo compartment and an air conditioner, the door-exclusion zone having a maximum height that is higher than a bottom edge of the door opening and lower than a top edge of the door opening, (ii) a rail joined to a major surface of the side wall, (iii) an arm assembly pivotably anchored at a first end thereof to the side wall, and (iv) a door comprising a first portion slidably engaged with the rail and a second portion pivotably coupled to a second end of the arm assembly, the method comprising:
a. opening the door by moving the door from a closed-door position aligned with the door opening to an open-door position higher in its entirety than the door-exclusion zone in its entirety, along a travel-path constrained by arrangement of the arm assembly and rail to avoid impingement upon the door-exclusion zone; and
b. closing the door by moving the door along the travel-path from the open-door position to the closed-door position,
wherein (i) the closing includes (A) moving the door in a downward vector and (B) moving the door in a lateral vector away from the door-exclusion zone, and (ii) the opening includes: (A) moving the door in an upward vector and (B) moving the door in a lateral vector toward the door-exclusion zone.
6. A method of operating a vehicle, the vehicle comprising: (i) a side wall shaped to define a door opening and a door-exclusion zone comprising at least one of a wheel well, a cargo compartment and an air conditioner, the door-exclusion zone having a maximum height that is higher than a bottom edge of the door opening and lower than a top edge of the door opening, (ii) a rail joined to a major surface of the side wall, (iii) an arm assembly pivotably anchored at a first end thereof to the side wall, and (iv) a door comprising a first portion slidable engaged with the rail and a second portion pivotably coupled to a second end of the arm assembly, the method comprising:
a. opening the door by moving the door from a closed-door position aligned with the door opening to an open-door position higher in its entirety than the door-exclusion zone in its entirety, along a travel-path constrained by arrangement of the arm assembly and rail to avoid impingement upon the door-exclusion zone; and
b. closing the door by moving the door along the travel-path from the open-door positon to the closed-door position,
wherein the side wall is formed to include a door pocket therewithin, the major surface is a major internal surface of the door pocket, and the arm assembly is pivotably anchored at a first end thereof within the door pocket.
7. The method of claim 6 , wherein the travel-path is disposed entirely within a volume consisting of the doorframe and the door pocket.
