Motorized door screen and shade assembly
View Patent ↗A motorized door shade assembly is disclosed, including a housing containing a motor. The motor operates a gear assembly to open and close a shade screen via a pull bar. Two or more springs biased to pull the pull bar, the pull bar moving along a track system configured to lock a zipper into at least one track. The pull bar moves horizontally to open and close the shade screen.
1 . A motorized door shade assembly comprising:
a housing containing a motor, the motor to operate a gear system including at least one pulley and a cord spooled about the pulley to open and close a shade screen via a pull bar;
two or more springs biased to maintain tension on the cord during motorized extension and retraction of the pull bar, the pull bar moving along a track system configured to lock a zipper into the track system, wherein the track system comprises a pair of channels, wherein one of the channels is configured to receive and engage the zipper fixed to opposing vertical edges of the shade screen, the zipper being guided and retained within the channels during extension and retraction, and
wherein the pull bar moves horizontally to extend and retract the shade screen along at least one of a top, bottom, or side edge of the shade screen to extend and retract the shade screen, maintaining the zipper in continuous alignment with the track system, and wherein the shade screen is rollable upon a roller concealed within the housing when in a retracted position.
2 . The motorized door shade assembly of claim 1 , wherein the shade screen is constructed of a sufficiently flexible material to be retained within the housing.
3 . The motorized door shade assembly of claim 1 , wherein the housing contains the roller to roll and unroll the shade screen when transitioning between an extended position and a retracted position.
4 . The motorized door shade assembly of claim 1 , wherein the track system is positioned on a top portion and a bottom portion of the housing.
5 . The motorized door shade assembly of claim 4 , wherein the track system permits the sliding engagement between the track system and the shade screen.
6 . The motorized door shade assembly of claim 1 , wherein the gear system is comprised of a plurality of gears operated via the motor, the gear system contained within the housing.
7 . The motorized door shade assembly of claim 1 , wherein the gear system is attached to the cord connected to the pull bar to move the pull bar between the retracted position and the extended position.
8 . The motorized door shade assembly of claim 1 , wherein the at least one pulley includes a plurality of pulleys to receive the cord.
9 . A motorized door shade assembly, comprising:
a housing including a left side portion, a right side portion, a top portion and a bottom portion, the housing containing a motor, the motor to operate a gear system including at least one pulley and a cord spooled about the pulley to open and close a shade screen via a pull bar; and
two or more springs biased to maintain tension on the cord during motorized extension and retraction of the pull bar, the pull bar moving along a track system configured to lock a zipper into the track system provided on the top portion and the bottom portion, the track system including at least one channel to permit the sliding engagement between the shade screen and the track system, wherein the track system comprises a pair of channels, wherein one of the channels is configured to receive and engage the zipper fixed to opposing vertical edges of the shade screen, the zipper being guided and retained within the channels during extension and retraction, and
wherein the pull bar moves horizontally to extend and retract the shade screen along at least one of a top, bottom, or side edge of the shade screen to extend and retract the shade screen, maintaining the zipper in continuous alignment with the track system, and wherein the shade screen is rollable upon a roller concealed within the housing when in a retracted position.
10 . The motorized door shade assembly of claim 9 , wherein the shade screen is constructed of a sufficiently flexible material to be retained within the housing.
11 . The motorized door shade assembly of claim 9 , wherein the housing contains the roller to roll and unroll the shade screen when transitioning between an extended position and a retracted position.
12 . The motorized door shade assembly of claim 9 , wherein the gear system is comprised of a plurality of gears operated via the motor, the gear system contained within the housing.
13 . The motorized door shade assembly of claim 9 , wherein the gear system is attached to the cord connected to the pull bar to move the pull bar between the retracted position and the extended position.
14 . The motorized door shade assembly of claim 9 , wherein the at least one pulley includes a plurality of pulleys to receive the cord.
15 . A motorized door shade assembly, comprising:
a housing including a left side portion, a right side portion, a top portion and a bottom portion, the housing containing a motor, the motor to operate a gear system including at least one pulley and a cord spooled about the pulley to open and close a shade screen via a pull bar; and
at least one spring biased to maintain tension on the cord during motorized extension and retraction of the pull bar in a lateral motion via the gear system, the gear system to spool the cord wrapped around the pulley attached to the pull bar, the pull bar moving along a track system configured to lock a zipper into the track system provided on the top portion and the bottom portion, the track system including at least one channel to permit the sliding engagement between the shade screen and the track system, wherein the track system comprises a pair of channels, wherein one of the channels is configured to receive and engage the zipper fixed to opposing vertical edges of the shade screen, the zipper being guided and retained within the channels during extension and retraction, and
wherein the pull bar moves horizontally to extend and retract the shade screen along at least one of a top, bottom, or side edge of the shade screen to extend and retract the shade screen, maintaining the zipper in continuous alignment with the track system, and wherein the shade screen is rollable upon a roller concealed within the housing when in a retracted position.
