Abstract

A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

First claim

What is claimed is:

1. A pressurized gate apparatus that is engaged between first and second vertically running surfaces and off a floor extending between the two vertically running surfaces, comprising:
a) a barrier frame in generally a first plane;
b) a gate engaged to the barrier frame and swingable into and out of the barrier frame and into and out of said first plane, said gate having a pivot side and a latch side;
c) the barrier frame having a first inner vertical support member, a first outer vertical support member, a first upper horizontally extending portion, and a first lower horizontally extending portion, the first inner and outer vertical support members extending parallel to each other, the first upper and lower horizontally extending portions extending parallel to each other, the first inner vertical support member being adjacent to the pivot side of the gate, the first inner vertical support member having an axis;
d) the barrier frame further having a second inner vertical support member, a second outer vertical support member, a second upper horizontally extending portion, and a second lower horizontally extending portion, the second inner and outer vertical support members extending parallel to each other, the second upper and lower horizontally extending portions extending parallel to each other, the second inner vertical support member being adjacent to the latch side of the gate, the second inner vertical support member having an axis, the second lower horizontally extending portion having an axis;
e) a first and upper pivot connection between the gate and the barrier frame;
f) a second and lower pivot connection between the gate and the barrier frame;
g) the barrier frame being a pressure frame and including first and second ends, the first end including the first inner and outer vertical support members, the second end including the second inner and outer vertical support members;
h) each of the second inner and outer vertical support members of the second end of the barrier frame manufactured to be obtuse relative the axis of the second lower horizontally extending portion of the barrier frame;
i) said gate being between said first and second ends;
j) the first and second ends being relatively squeezable together between said two vertically running surfaces to thereby resiliently push back against the vertically running surfaces such that the barrier frame is fixed between the two vertically running surfaces and off the floor and such that the axis of each of the second inner and outer vertical support members and the axis of the second lower horizontally extending portion are pushed into about a right angle relationship;
k) the first and second ends being relatively squeezable together by first, second, third, and fourth screw apparatus, the first screw apparatus engaging the first upper horizontally extending portion of the barrier frame, the second screw apparatus engaging the first lower horizontally extending portion of the barrier frame, the third screw apparatus engaging the second upper horizontally extending portion of the barrier frame, and the fourth screw apparatus engaging the second lower horizontally extending portion of the barrier frame, the first and second screw apparatus engaging the first vertically running surface, the third and fourth screw apparatus engaging the second vertically running surface;
l) the gate including first, second, third, and fourth corner portions, the gate engaging the barrier frame at each of the first, second, third, and fourth corner portions, the first and upper pivot connection being engaged at the first corner portion, the second and lower pivot connection being engaged at the second corner portion, an upper latch being engaged at the third corner portion and extending between the third corner portion and the barrier frame, and a lower latch being engaged at the fourth corner portion and extending between the fourth corner portion and the barrier frame;
m) said first and upper and second and lower pivot connections establishing a swing axis on which the gate swings, said swing axis being oblique relative to the vertical axis of the first inner vertical support member; and
n) the first and upper pivot connection between the gate and the barrier frame comprising:
i) a swinging portion that is fixed to the gate such that, when the gate swings, the swinging portion swings with the gate;
ii) a receiver portion that is fixed to the frame, the receiver portion receiving the swinging portion that is fixed to the gate;
iii) the receiver portion having a face, the face having a flat portion; and
iv) the flat portion being disposed obliquely relative to the vertical axis of the first inner vertical support member, the swinging portion riding on the flat portion.

2. A pressurized gate apparatus that is engaged between first and second vertically running surfaces and off a floor extending between the two vertically running surfaces, comprising:
a) a barrier frame in generally a first plane;
b) a gate engaged to the barrier frame and swingable into and out of the barrier frame and into and out of said first plane, said gate having a pivot side and a latch side;
c) the barrier frame having a first inner vertical support member, a first outer vertical support member, a first upper horizontally extending portion, and a first lower horizontally extending portion, the first inner and outer vertical support members extending parallel to each other, the first upper and lower horizontally extending portions extending parallel to each other, the first inner vertical support member being adjacent to the pivot side of the gate, the first inner vertical support member having an axis;
d) the barrier frame further having a second inner vertical support member, a second outer vertical support member, a second upper horizontally extending portion, and a second lower horizontally extending portion, the second inner and outer vertical support members extending parallel to each other, the second upper and lower horizontally extending portions extending parallel to each other, the second inner vertical support member being adjacent to the latch side of the gate, the second inner vertical support member having an axis, the second lower horizontally extending portion having an axis;
e) a first and upper pivot connection between the gate and the barrier frame;
f) a second and lower pivot connection between the gate and the barrier frame;
g) the barrier frame being a pressure frame and including first and second ends, the first end including the first inner and outer vertical support members, the second end including the second inner and outer vertical support members;
h) each of the second inner and outer vertical support members of the second end of the barrier frame manufactured to be obtuse relative the axis of the second lower horizontally extending portion of the barrier frame;
i) said gate being between said first and second ends;
j) the first and second ends being relatively squeezable together between said two vertically running surfaces to thereby resiliently push back against the vertically running surfaces such that the barrier frame is fixed between the two vertically running surfaces and off the floor and such that the axis of each of the second inner and outer vertical support members and the axis of the second lower horizontally extending portion are pushed into about a right angle relationship;
k) the first and second ends being relatively squeezable together by first, second, third, and fourth screw apparatus, the first screw apparatus engaging the first upper horizontally extending portion of the barrier frame, the second screw apparatus engaging the first lower horizontally extending portion of the barrier frame, the third screw apparatus engaging the second upper horizontally extending portion of the
