Definitions

  • the present invention relates to a door assembly, particularly to a door assembly with a door shutter which is vertically moved to open or close the door on which the door assembly is installed.
  • a roller door assembly could be very advantageously used as a door for some special sites, for example, a garage or a factory since such a door assembly has a relatively simple structure, can be easily driven by electricity and can conceal an inside of the garage or factory when the door is closed.
  • a door assembly generally consists of a motor mounted on a top of the door, a reduction gearing coupled with the motor, a roller coupled with the reduction gearing and laterally extending through the top of the door, a pair of guiding channels defined on two sides of the door, a door shutter made of a plurality of steel strips pivotably connected with each other and having a top edge fixedly connected with the roller and two side edges guided by the guiding channels.
  • the roller rotates to extend the roller door shutter whereby the door shutter can follow the guiding channels to move downwardly to close the door.
  • the roller rotates to wind up the door shutter therearound to open the door.
  • roller door assembly is proved to be able to function well, it still has the following disadvantages.
  • the present invention therefore is aimed to provide an improved door assembly with a vertically-moved door shutter to mitigate and/or obviate the aforementioned problems.
  • An objective of the present invention is to provide a door assembly which has the advantages of the conventional roller door assembly but without the disadvantages thereof.
  • Another objective of the present invention is to provide a door assembly with a door shutter vertically moved wherein when the door assembly is operated little noise will be generated.
  • a further objective of the present invention is to provide a door assembly with a door shutter vertically moved wherein a movement of the door shutter will not cause scratches on surfaces of the door shutter.
  • a still further objective of the present invention is to provide a door assembly with a door shutter vertically moved wherein when the door shutter is driven to move upwardly to open the door, the door shutter does not wind up on a drive wheel and an idling wheel of the present invention which are rotatably mounted on an axle, so that the weight of the door shutter will not entirely supported by the axle, whereby even when the door shutter is relatively heavy since it has a large length, the diameter of the axle does not need to be increased.
  • a main portion of a door assembly 1 in accordance with the present invention comprises a pair of mounting plates 10, 10' for mounting the door assembly 1 on two sides of a top of a door (not shown).
  • An axle 20 is fixedly mounted on the two mounting plates 10, 10' and extended therebetween.
  • a drive wheel 22 and an idling wheel 22' are rotatably mounted on the axle 20 and located respectively near the mounting plate 10 and 10'.
  • a pair of springs 24, 24' respectively have a first end fixedly connected with the drive wheel 22 and the idling wheel 22' and a second end fixedly connected with one of a pair of anchors 26, 26' which in turn are fixedly mounted on the axle 20.
  • the springs 24, 24' When the drive wheel 22 and idling wheel 22' rotate, the springs 24, 24' are twisted. Such springs 24, 24' are used to store energy when a door shutter 30 is driven to move downwardly. The energy stored in the springs 24, 24' is used to facilitate the lifting of the door shutter 30.
  • a bracket 102 is fixedly attached to an inside of the mounting plate 10.
  • An electric driving mechanism 14 is used to drive the drive wheel 22.
  • the driving mechanism 14 includes a motor 144 mounted on the bracket 102, and a reduction gearing/clutch unit 142 having an input side coupled with the motor 144 and an output side selectively coupled with the drive wheel 22 by controlling the position of a control rod 146.
  • the control rod 146 When the control rod 146 is moved to a specific position, the drive wheel 22 is decoupled from the reduction gearing/clutch unit 142 whereby the door shutter 30 of the present door assembly 1 is manually motivated. Alternatively, the door shutter 30 can be motivated by the motor 144.
  • Taiwan Utility Model Patent No. 94656 Since the driving mechanism 14 is not concerned with the inventive characteristics of the present invention and has been disclosed by Taiwan Utility Model Patent No. 94656, a detailed description thereof is omitted here.
  • a door shutter guiding channel consisting of a horizontal guiding channel 40, an arc-shaped guiding channel 12 and a vertical guiding channel 42 is defined on each of the mounting plates 10, 10' and extends therefrom. However, in the drawings only the guiding channel concerning the mounting plate 10 is shown.
  • the arc-shaped guiding channel 12 is defined by a block 122 having a configuration like a right-angled triangle and defining an arc-shaped side and an arc-shaped plate 124 opposite to the arc-shaped side.
  • the horizontal guiding channel 40 is defined by a first pair of flat steel plates 402, 404 horizontally extending inwardly respectively from rear, top ends of the block 122 and plate 124 to a position wherein the length of the horizontal guiding channel 40 is substantially the same as that of the door shutter 30.
  • the vertical guiding channel 42 is defined by a second pair of flat steel plates 422, 424 vertically extending downwardly respectively from front, bottom ends of the block 122 and plate 124 to a bottom of the door.
  • Each of the drive wheel 22 and idling wheel 22' is made of hard plastics and defines a series of teeth 222 around its circumferential periphery.
  • the door shutter 30 is made of a single spring steel sheet and is formed to have a corrugated/ribbed configuration with a plurality of concave portions 302 and convex portions 304. When the door shutter 30 is extended around the drive wheel 22 and idling wheel 22' (as better seen in Fig.
  • the upper portion of the door shutter 30 is guided to run along the horizontal guiding channels 40 and supported by the flat steel plates 404 defining the channels 40, rather to wind up on the drive wheel 22 and idling wheel 22' so that the weight of the door shutter 30 will not be supported entirely by the axle 20.
  • the noise generated due to the drive wheel 22 and idling wheel 22' engaging the door shutter 30 is not significant.
  • Fig. 4 shows a preferred embodiment of the door shutter 30.
  • the door shutter 30 includes a plurality of sliders 32 fixedly attached at an underside of some of the convex portions 304 and configured to have a semi-circular shape with a tip protruding from the two lateral edges of the door shutter 30.
  • the door shutter 30 is guided to move along the guiding channels, only the tip of each of the sliders 32 will contact inner walls of the guiding channels.
  • two flexible strips 34 made of nylon fabric or the like are attached to two sides of a surface of the door plate 30 which will be in contact with the flat steel plates 404, 424 and the arc-shaped plate 124, when the door shutter 30 is driven to move along the guiding channels.
