Abstract
A shutter which has a number of wide slats connected to each other by a hinge mechanism with the slats remaining separate so that an opening for a side gate can be formed at a desired position on the shutter. The slats of the side gate are connected vertically to each other or horizontally with other slats and the connection can be released at any time desired. The side gate provided at a part of the shutter allows access even when the shutter is closed, yet the side gate can be folded as a part of the shutter.
Claims15
A shutter comprising a number of slats connected to each other by a hinge mechanism in which the slats are connected yet separable, an opening for a side gate formed at a desired position, and having slats and a handle comprising vertical and horizontal connecting rods, wherein the slats of the side gate are releasably connected vertically to each other by the vertical rods and are horizontally connected to the shutter slats by the horizontal rods, whereby the horizontal connection is releasably connected and some of said horizontal rods which connect the side gate to the shutter in order to shut the side gate and the handle which operates the rods are connected by wires and upon releasing the horizontal connection, said side gate slats are simultaneously vertically connected.
A shutter capable of repeatedly sliding on guide posts from a closed position to an open position such that said shutter includes a multiplicity of rollers some of which are larger than others, said shutter being stored on support means when in the open position, said shutter comprising:
- a plurality of slats having ends and longitudinal edges;
- a plurality of roller hinge mechanisms arranged for rolling on said guide posts and said support means;
- said hinge mechanism comprising
- connecting means which includes pairs of larger rollers and pairs of smaller rollers arranged alternately to connect said slats to one another such that said longitudinal edges of said slats are adjacent when said shutter is in the closed position and are separable yet connected when in open positions.
A side gate for a shutter, said shutter being made of a plurality of slats wherein said slats are connected at either end yet remain separable, said side gate comprising:
- portions of said plurality of shutter slats;
- a locking mechanism comprising vertical locking means capable of vertically locking said slat portions together, and
- horizontal locking means capable of horizontally locking said slat portions together with said shutter slats, whereby unlocking said slat portions with said shutter simultaneously locks the slat portions together;
- and
- horizontal hinge means capable of hinging said slat portions to said shutter slats.
