Door Designs

[0014] FIGS. 3A and 3B show a first door design of the present disclosure. FIG. 3A shows the doors in respective closed positions, and FIG. 3B shows the doors in respective open positions.

[0015] The recreational vehicle 300 includes a first door 302 and a second door 304. When in the closed position shown in FIG. 3A, the first door 302 and the second door 304 are attached to each other (e.g., latched to each other). For example, one or both of the doors can include a handle that a user can pull, rotate, and/or push to latch or unlatch one of the doors to the other door. In certain embodiments, the doors are designed such that the first door 302 needs to be opened (or at least unlatched from the second door 304) before the second door 304 can be opened.

[0016] As shown in FIG. 3A, the first door 302 and the second door 304 can have lengths (in the horizontal direction) that are substantially similar to each other such that each door covers approximately half of the entryway opening of the recreational vehicle 300.

[0017] The first door 302 is coupled to a pillar 306 of the recreational vehicle 300 such that the first door 302 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the first door 302 to the pillar 306 to allow the first door 302 to rotate between open and closed positions. The first door 302 can rotate around an axis that extends substantially along a vertical direction.

[0018] The second door 304 is a sliding door. The second door 304 is coupled to the body of the recreational vehicle 300 via one or more door tracks 308A (shown in FIG. 3A), 308B (FIG. 3B), and 308C (FIG. 3B). The door tracks 308-308C can include a slot in which a portion of the second door 304 extends through. The second door 304 can include rollers or similar features that fit into respective door tracks 308A-C such that the second door 304 can be slid open and slid closed. In certain embodiments, the one or more door tracks 308A-C are factory door tracks that are utilized for the second door 304 after the original factory sliding door is removed and replaced by the first door 302 and the second door 304. The second door 304 is shorter lengthwise compared to the original factory sliding door. And either or both of the first door 302 and the second door 304 can include windows (shown in dotted lines in FIGS. 3A and 3B).

[0019] FIGS. 4A and 4B show a second door design of the present disclosure. FIG. 4A shows the doors in respective closed positions, and FIG. 4B shows the forward doors in respective open positions.

[0020] The recreational vehicle 400 includes a first door 402 and a second door 404. In certain embodiments, the recreational vehicle 400 includes a third door 406 while in other embodiments a stationary body panel is positioned in place of where the third door 406 is shown in FIGS. 4A and 4B. In embodiments that feature the third door 406, the third door 406 can be a sliding door or a rotatable door.

[0021] The first door 402 is positioned above the second door 404. When in the closed position shown in FIG. 4A, the first door 402 and the second door 404 are attached to each other (e.g., latched to each other). For example, one or both of the doors can include a handle that a user can pull, rotate, and/or push to latch or unlatch one of the doors to the other door. In certain embodiments, the doors are designed such that the first door 402 needs to be opened (or at least unlatched from the second door 404) before the second door 404 can be opened.

[0022] As shown in FIG. 4A, the first door 402 is longer than the second door 404 in the vertical direction. For example, the first door 402 can have a length in the vertical direction that is approximately twice the length of the second door 404. In the horizontal direction, the first door 402 and the second door 404 can have lengths that are substantially similar to each other.

[0023] The first door 402 is coupled to an upper portion 408 (e.g., an upper frame, a ceiling) of the recreational vehicle 400 such that the first door 402 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the first door 402 (at a first end of the first door 402) to the upper portion 408 to allow the first door 402 to rotate between open and closed positions. As the first door 402 moves from the closed position to the open position, a second end of the first door 402 rotates with respect to the one or more hinges approximately 90 degrees (e.g., 90 degrees+/?10 degrees). In certain embodiments, one or more assist devices 410 (e.g., motors, actuators, struts such as gas struts) are coupled to the first door 402 such that opening and/or closing the first door 402 requires less force from a user.

[0024] The second door 404 is coupled to a lower portion 412 (e.g., a lower frame, a floor) of the recreational vehicle 400 such that the second door 404 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the second door 404 (at a first end of the second door 404) to the lower portion 412 to allow the second door 404 to rotate between open and closed positions. As the second door 404 moves from the closed position to the open position, a second end of the second door 404 rotates with respect to the one or more hinges such that the second door 404 either touches the ground or hovers above the ground. In certain embodiments, the second door 404 rotates between 90 and 180 degrees such as approximately 125 degrees (e.g., 125 degrees+/?10 degrees). In certain embodiments, one or more assist devices (e.g., motors, actuators, struts such as gas struts) are coupled to the second door 404 such that opening and/or closing the second door 404 requires less force from a user.

[0025] The second door 404 can include one or more steps 414. When the second door 404 is closed, the steps 414 are positioned within the recreational vehicle 400 and face the interior of the recreational vehicle 400. The steps 414 help passengers with entering or exiting the recreational vehicle 400. In other embodiments, the second door 404 includes a ramp instead of steps such so that passengers can use a wheelchair to enter and exit the recreational vehicle 400.

[0026] FIGS. 5A and 5B show a third door design of the present disclosure. FIG. 5A shows the doors in respective closed positions, and FIG. 5B shows the doors in respective open positions. The third door design is similar to the second door design but utilizes a single third upper door. The recreational vehicle 500 includes a first door 502, a second door 504, and a third door 506.

[0027] The first door 502 is positioned above the second door 504. When in the closed position shown in FIG. 5A, the first door 502 and the second door 504 are attached to each other (e.g., latched to each other). For example, one or both of the doors can include a handle that a user can pull, rotate, and/or push to latch or unlatch one of the doors to the other door. In certain embodiments, the doors are designed such that the first door 502 needs to be opened (or at least unlatched from the second door 504) before the second door 504 can be opened.

[0028] As shown in FIG. 5A, the first door 502 is longer than the second door 504 in the vertical direction. For example, the first door 502 can have a length in the vertical direction that is approximately twice the length of the second door 504. In the horizontal direction, the first door 502 and the second door 504 can have lengths that are substantially similar to each other.

[0029] The first door 502 is coupled to an upper portion 508 (e.g., an upper frame, a ceiling) of the recreational vehicle 500 such that the first door 502 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the first door 502 (at a first end of the first door 502) to the upper portion 508 to allow the first door 502 to rotate between open and closed positions. As the first door 502 moves from the closed position to the open position, a second end of the first door 502 rotates with respect to the one or more hinges approximately 90 degrees (e.g., 90 degrees+/?10 degrees). In certain embodiments, one or more assist devices 510 (e.g., motors, actuators, struts such as gas struts) are coupled to the first door 502 such that opening and/or closing the first door 502 requires less force from a user.

[0030] The second door 504 is coupled to a lower portion 512 (e.g., a lower frame, a floor) of the recreational vehicle 500 such that the second door 504 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the second door 504 (at a first end of the second door 404) to the lower portion 512 to allow the second door 504 to rotate between open and closed positions. As the second door 504 moves from the closed position to the open position, a second end of the second door 504 rotates with respect to the one or more hinges such that the second door 504 either touches the ground or hovers above the ground. In certain embodiments, the second door 504 rotates between 90 and 180 degrees such as approximately 125 degrees (e.g., 125 degrees+/?10 degrees). In certain embodiments, one or more assist devices (e.g., motors, actuators, struts such as gas struts) are coupled to the second door 504 such that opening and/or closing the second door 504 requires less force from a user.

[0031] The second door 504 includes one or more steps 514. When the second door 504 is closed, the steps 514 are positioned within the recreational vehicle 500 and face the interior of the recreational vehicle 500. The steps 514 help passengers with entering or exiting the recreational vehicle 500. In other embodiments, the second door 404 includes a ramp instead of steps such so that passengers can use a wheelchair to enter and exit the recreational vehicle 400.

[0032] The third door 506 is positioned above a stationary panel 516 and can be coupled to the upper portion 508 of the recreational vehicle 500 such that the third door 506 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the third door 506 (at a first end of the third door 506) to the upper portion 508 to allow the third door 506 to rotate between open and closed positions. The third door 506 can be latched to the stationary panel 516 in the closed position and unlatched to move to the open position. For example, the third door 506 can include a handle, latch, etc. that is used to unlatch the third door 506 from the stationary panel 516.

[0033] As the third door 506 moves from the closed position to the open position, a second end of the third door 506 rotates with respect to the one or more hinges approximately 90 degrees (e.g., 90 degrees+/?10 degrees). In certain embodiments, one or more assist devices (e.g., motors, actuators, struts such as gas struts) are coupled to the third door 506 such that opening and/or closing the third door 506 requires less force from a user.

[0034] When in the open position, the third door 506 (and the first door 502) can function similar to an awning and provide shelter from rain and/or shade. The third door 506 can be positioned above a kitchen area of the recreational vehicle 500. For example, a stovetop or countertop can be positioned immediately behind the stationary panel 516.

[0035] FIGS. 6A and 6B show a fourth door design of the present disclosure. FIG. 6A shows the doors in respective closed positions, and FIG. 6B shows the doors in respective open positions. The fourth door design is similar to the third door design but utilizes a second door that opens around a vertical axis instead of a horizontal axis. The recreational vehicle 600 includes a first door 602, a second door 604, and a third door 606.

[0036] The first door 602 is positioned above the second door 604. When in the closed position shown in FIG. 6A, the first door 602 and the second door 604 are attached to each other (e.g., latched to each other). For example, one or both of the doors can include a handle that a user can pull, rotate, and/or push to latch or unlatch one of the doors to the other door. In certain embodiments, the doors are designed such that the first door 602 needs to be opened (or at least unlatched from the second door 604) before the second door 604 can be opened.

[0037] As shown in FIG. 6A, the first door 602 and the second door 604 can have lengths (in the horizontal direction) that are substantially similar to each other such that each door covers approximately half of the entryway opening of the recreational vehicle 600. Further, in the vertical direction, the first door 602 and the second door 604 can have lengths that are substantially similar to each other.

[0038] The first door 602 is coupled to an upper portion 608 (e.g., an upper frame, a ceiling) of the recreational vehicle 600 such that the first door 602 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the first door 602 (at a first end of the first door 602) to the upper portion 608 to allow the first door 602 to rotate between open and closed positions. As the first door 602 moves from the closed position to the open position, a second end of the first door 602 rotates with respect to the one or more hinges approximately 90 degrees (e.g., 90 degrees+/?10 degrees). In certain embodiments, one or more assist devices 610 (e.g., motors, actuators, struts such as gas struts) are coupled to the first door 602 such that opening and/or closing the first door 602 requires less force from a user.

[0039] The second door 604 is coupled to a pillar 612 of the recreational vehicle 600 such that the second door 604 can be rotated (e.g., pivoted or swung) to the open position. For example, one or more hinges can couple the second door 604 to the pillar 612 to allow the second door 604 to rotate between open and closed positions. The second door 604 can rotate around an axis that extends substantially along a vertical direction. When in the closed position, the second door 604 can be latched to a stationary panel 614.
