Claims22
A portable, variable width gate for doorways and the like, comprising:
- first and second gate sections of predetermined height and width, each comprising
- a rectangular external frame defined by top and bottom substantially horizontal cross members and substantially vertical side members;
- a substantially horizontal middle cross member disposed between the top and bottom members and interconnecting the side members;
- a mesh section interconnecting the respective frame members;
- means for connecting the gate sections for free relative sliding movement between a first position of minimum gate width and a second position of maximum gate width;
- and operator means for fixing the relative positions of the first and second gate sections at a predetermined width comprising:
- handle drive means carried by the middle cross member of one of said gate sections for movement through first and second ranges of positions;
- drivable means carried by the middle cross member of the other of said gate sections;
- the handle drive means comprising a first operative portion engageable with the drivable means and cooperable therewith to effective relative movement between the first and second gate sections when the handle drive means is moved through the first position range, and a second operative portion incapable of engaging the drivable means when the handle drive means is moved through said second position range;
- and means for selectively fixing the handle drive means in a plurality of discrete positions within said first position range.

A variable width gate for doorways and the like defined by opposed supports, comprising:
- first and second gate sections each having a predetermined width defined by opposite sides;
- means for connecting the gate sections for free relative sliding movement between a first position of minimum gate width and a second position of maximum gate width;
- hinge means disposed on one side of one of the gate sections for pivotally connecting the gate to one of the opposed doorway supports;
- first latching means disposed on the opposite side of the other of said gate sections;
