Abstract

A stop device that is used to prevent unauthorized opening of sliding closures, such as windows and doors, which is esthetically pleasing, is adjustable in length and includes removable decorative accessory items. The stop device includes first and second elongated extension members and a locking mechanism. The locking mechanism includes first and second levers which engage the first and second members, respectively, to lock the first and second members with respect to the locking mechanism.

Claims7

Dependent claims

A stop device, for use with a closure having a sliding panel movable with respect to a frame, comprising:

a first elongated extension member;
a second elongated extension member;
and a locking mechanism;
said locking mechanism having a locked position and an unlocked position, said first elongated extension member being slidably movable between a fully extended first position and a non-extended second position when said locking mechanism assumes said unlocked position, said second elongated extension member being slidably movable between a fully extended first position and a non-extended second position when said locking mechanism assumes said unlocked position, said first position of said first elongated extension member being opposed to said first position of said second elongated extension member, said first elongated extension member and said second elongated extension member being parallel to each other, each said member being fixedly engaged within said locking mechanism when said locking mechanism assumes said locked position, said locking mechanism comprising:
a housing;
a first lever;
a second lever;
a first pair of springs;
and a second pair of springs;
said housing having a central cavity therethrough which slidably receives said members therethrough, said housing having a first aperture for receiving said first lever therethrough, said housing having a second aperture for receiving said second lever therethrough, each said lever having a central cavity therethrough which slidably receives said members therethrough, said first lever being of a length to extend from within said housing outwardly from said first aperture, said second lever being of a length to extend from within said housing outwardly from said second aperture, said first pair of springs being in contact with said first lever, and said second pair of springs being in contact with said second lever,
wherein:
when said locking mechanism is in said locked position, said first pair of springs applies tensional force against said first lever to force said first lever into contact with said first member and restricts movement of said first member, and said second pair of springs applies tensional force against said second lever to force said second lever into contact with said second member and restricts movement of said second member.
