Abstract
A shutter with an emergency exit has blocks attached to it. The projection of the blocks from the shutter match the projection of hinges that hold the emergency exit, such that the shutter winds evenly around a drum in a shutter box. The shutter also has reinforced horizontal shutter materials directly above and directly below the emergency exit to keep the shutter horizontally balanced as the shutter is wound into or out of the shutter box. The shutter also includes shock absorbing material where the emergency exit and the shutter meet. The shock absorbing material reduces noise from the contact of the emergency exit and the shutter and also prevents smoke from transferring from one side of the shutter to the other.
Claims13
A shutter apparatus comprising:
- a shutter having a plurality of vertically coupled horizontal shutter materials, each of said horizontal shutter materials having equal top and bottom widths;
- a shutter box equipped with the means for winding said shutter into and out of said shutter box;
- a guide rail set up at both sides of said shutter and guiding an ascent and descent motion of said shutter;
- an emergency exit at one side of a suitable part of said shutter to ascent and descent with said shutter;
- hinges connecting said emergency exit to said shutter such that said emergency exit pivots about said hinges between an open position and closed position;
- a block attached between ends of said shutter materials to correct a winding unbalance of said shutter in said shutter box caused by said hinges projecting from said shutter materials;
- a projection height of said block from said shutter materials being the same height as a projection height of said hinges from said shutter materials such that said shutter winds evenly into said shutter box;
- a bottom bar having the length to cover an entire width of said shutter;
- both ends of said bottom bar being inserted into said guide rail;
- said bottom bar fixedly attached at a lowest shutter material of said shutter;
- and
- a shock absorbing material mounted on said emergency exit such that said shock absorbing material is between said emergency exit and said shutter except where said shutter and said emergency exit are hingably connected when said emergency exit is in said closed position, whereby said shock absorbing material prevents smoke from leaking around a perimeter of said emergency exit.

A shutter apparatus comprising:
- a plurality of vertically coupled shutter materials;
- said plurality including shorter ones of Said plurality of shutter materials which are shorter than a remainder of said plurality of shutter materials;
- an emergency exit attached to said shorter ones of said plurality of shutter materials by hinges;
- a shutter box including means for winding said plurality of shutter materials around a drum in said shutter box;
- means for preventing a winding unbalance including blocks attached between ends of said shorter ones of said plurality of shutter materials;
- a projection height of said blocks out of said shutter corresponding to another projection height of said hinges such that said shutter winds evenly around said drum;
- and
- shock absorbing material placed where said emergency exit contacts said shutter whereby noise is reduced and smoke is prevented from infiltrating said shutter apparatus.

- at least one block attached between said hinges and another end of said shorter ones of said vertically coupled shutter materials to correct a winding unbalance of said shutter in said shutter box caused by said hinges projecting from said shutter;
- and
- a projection height of said at least one block being the same height as a projection height of said hinges from said shutter such that said shutter winds evenly into said shutter box.
