Abstract

A child and pet security gate is disclosed for use in larger passageways. The security gate includes multiple (at least three) telescopically sliding panels that extend to close the passageway and retract to minimum width. The extension and retractive relative sliding movement is progressive; thus, only one panel moves relative to another until it reaches its fully extended or retracted position. The security gate also includes mounting hardware that permits the gate to either hingeably pivot or to be removed for storage. A latching member securely closes the gate and is operable only by an adult.

Claims27

Dependent claims

A security gate for a passageway comprising:

at least three gate panel means;
connection means for connecting each of said gate panel means to adjacent gate an panel means for relative telescoping movement with respect thereto, with the gate panel means together moveable between a retracted and extended gate positions to open and close the passageway, wherein the relative movement from the retracted to the extended position is the reverse of the movement from the extended to the retracted position;
and control means for controlling the relative movement of said gate panel means between said retracted and extended gate positions so that relative movement is permitted between only two panels at a given time;
wherein said control means is constructed and arranged so that said relative movement is progressive as said gate panels are moved between said extended and retracted positions;
and
wherein said control means comprises:
first control member means mounted on at least one of said gate panel means for movement relative thereto between extended and retracted positions;
first biasing means for normally urging the first control member means to said extended position;
said first control member means comprising first projection means projecting laterally from one face of the gate panel means with the first control member means in its extended position, said first projection means constructed and disposed to be engaged by an adjacent gate panel means as it is moved toward its retracted gate position and to thereby cause the first control member means to move to its retracted position;
said first control member means further comprising second projection means projecting laterally from the opposite face of the gate panel means with the first control member means in its extended position, said second projection member means in its extended position, said second projection means being constructed and arranged to abuttably engage an adjacent gate panel means and prevent relative retractive movement therebetween, the second projection means being retracted from said abuttable engagement when the first control member means is moved to its retracted position.

7 more elements

A security gate for a passageway defined by opposed first and second members, comprising:

gate means having first and second sides sized to substantially occupy the width between said opposed members;
hinge means for mounting the first side of said gate means to said first opposed member and to permit the gate means to swing between open and closed positions;
and gate closure means for releasably connecting the second side of said gate means to the second opposed member of said passage, the gate closure means comprising:
first latching means disposed on the second side of said gate means and comprising a first elongated latching rail mounted to the second side of the gate means, and first alignable retention means disposed on said first latching rail;
second latching means mountable on the second opposed member of said passageway and comprising a second elongated latching rail, and second alignable retention means disposed on said second latching rail;
the first and second alignable retention means being constructed and arranged for mutual retaining engagement when alignably disposed, wherein one of said first and second alignable retention means comprise substantially vertical projecting pin means, and the other of said first and second alignable retention means comprise projecting loop means, the loop means being disposed to vertically receive the pin means in said mutual retaining engagement;
and interlocking means for releaseably interlocking the first and second latching means when the first and second alignable retention means are in mutual retaining engagement, the irterlocking means comprising an interlocking member mounted on said first latching rail, wherein the interlocking means is constructed and disposed to automatically interlock the first and second latching rails when said pin means is fully inserted into said loop means, the interlocking member comprising a deflectable leg member with a pawl member projecting therefrom, and a receptacle is formed in said second latching rail disposed to receive and retain the pawl member when said pin means is fully inserted into said loop means.

A security gate for a passageway defined by opposed first and second members comprising:

gate means having first and second sides sized to substantially occupy the width between said opposed members;
hinge means for mounting the first side of said gate means to said first opposed member and to permit the gate means to swing between open and closed positions;
and gate closure means for releasably connecting the second side of said gate means to said second opposed member;
the hinge means comprising:
a first hinge member mounted on the first side of the gate means;
a second hinge member mountable to the first opposed member of said passageway;
connection means for releasably and hingeably connecting the first and second hinge members for hinged, pivotal movement;
and latching means for releasably latching the first and second hinge members when they are hingeably connected, wherein the latching means comprises a latching member disposed on said first hinge member, the latching member comprising a deflectable leg member with a pawl member projecting from, and the first hinge member comprises a bearing member disposed to engageably deflect the pawl member and to be retained thereby when the pin means is fully inserted into said loop means.
