Abstract

A double door gate apparatus having a frame, a main gate and a secondary gate. The outer ends of the main and secondary gates are pivotally mounted to the frame. The inner ends of the main and secondary gates confront each other and swing in both ways independently of the other. The main and secondary gates are openable independently of the other. Prior to being opened, each of the main and secondary gates is lifted upwardly on its respective pivot axis to be disengaged from the frame. Portions of the frame work as stops to signal that the main and secondary gates have been lifted sufficiently to be openable.

First claim

What is claimed is:

1. A double door gate apparatus, comprising:
a) a frame having a first vertical support member, a second vertical support member, and a horizontal support member, the first and second vertical support members being spaced apart, and the first and second vertical support members engaged to the horizontal support member;
b) a main gate having an outer end and an inner end, the outer end of the main gate mounted to the first vertical support member of the frame on a first pivot axis, the inner end of the main gate swingable to open and close the main gate relative to the frame, the inner end of the main gate being swingable over the horizontal support member of the frame;
c) a second gate having an outer end and an inner end, the outer end of the second gate mounted to the second vertical support member of the frame on a second pivot axis, the inner end of the second gate being swingable to open and close the second gate relative to the frame, the inner end of the second gate being swingable over the horizontal support member of the frame, and the inner end of the second gate being adjacent to the inner end of the main gate when the main and second gates are in a closed position;
d) wherein the frame is an open top frame such that no horizontal support members extend from the first vertical support member to the second vertical support member other than said horizontal support member over which the main and second gates swing;
e) wherein the main gate is slideable vertically up and down on the first pivot axis, and wherein the second gate is slideable vertically up and down on the second pivot axis;
f) wherein the main gate comprises a first outer end vertical support member, a first inner end vertical support member, a first lower horizontal support member, a first upper horizontal support member, and a first internal support network of elongate members;
g) wherein the second gate comprises a second outer end vertical support member, a second inner end vertical support member, a second lower horizontal support member, a second upper horizontal support member, and a second internal support network of elongate members;
h) wherein the main gate is openable relative to the frame independently of the second gate such that the main gate is swingable relative to the frame when the second gate is fixed in a closed position to the frame;
i) wherein the second gate is openable relative to the frame independently of the main gate such that the second gate is swingable relative to the frame when the main gate is fixed in a closed position to the frame;
j) wherein the main gate is openable relative to the frame when the second gate is openable relative to the frame such that the main gate and second gate are concurrently swingable relative to the frame; and k) wherein the main gate includes a latch that is engagable with the horizontal support member and wherein the main gate is first lifted vertically to disengage the latch mechanism from the horizontal support member before the main gate is pivoted toward the open position.

2. The double door gate apparatus of claim 1 , wherein the main gate is engagable to and disengagable from the second gate such that the main gate is openable and closeable relative to the second gate and such that the second gate is openable and closeable relative to the main gate.

3. The double door gate apparatus of claim 1 , wherein the main gate is engagable to and disengagable from the horizontal support member of the frame such that the main gate is openable and closeable relative to the horizontal support member of the frame.

4. The double door gate apparatus of claim 1 , wherein the second gate is engagable to and disengagable from the horizontal support member of the frame such that the second gate is openable and closeable relative to the horizontal support member of the frame.

5. The double door gate apparatus of claim 1 , wherein the second gate is engagable to and disengagable from the second vertical support member of the frame such that the second gate is openable and closeable relative to the second vertical support member of the frame.

6. The double door gate apparatus of claim 1 , wherein the frame includes a first upper portion on the first vertical support member working as a first stop to limit vertical sliding of the main gate on the first pivot axis, and wherein the frame includes a second upper portion on the second vertical support member working as a second stop to limit vertical sliding of the second gate on the second pivot axis.

7. The double door gate apparatus of claim 1 , wherein, prior to opening the main gate relative to the frame, the main gate must be disengaged from the second gate and lifted vertically along the first pivot axis.

8. The double door gate apparatus of claim 1 , wherein, prior to opening the second gate relative to the frame, the second gate must be disengaged from the main gate and lifted vertically along the second pivot axis.

9. The double door gate apparatus of claim 1 , wherein the main gate and second gate are liftable along the first and second pivot axes, respectively, and engagable to each other concurrently.

10. The double door gate apparatus of claim 1 , wherein the main gate includes upper and lower inner ends, wherein the second gate includes upper and lower inner ends, and wherein the upper inner end of the main gate is engagable to and disengagable from the upper inner end of the second gate, and wherein the lower inner end of the main gate is engagable to and disengagable from the horizontal support member of the frame.

11. The double door gate apparatus of claim 1 , wherein the second gate includes a lower inner end and an outer upper end, wherein the lower inner end of the second gate is engagable to and disengagable from the horizontal support member of the frame, and wherein the outer upper end of the second gate is engagable to and disengagable from the second vertical support member of the frame.

12. The double door gate apparatus of claim 1 , and further comprising first and second shafts and first and second hand wheels, the first hand wheel turnable on the first shaft, the second hand wheel turnable on the second shaft, the first shaft engaged to the frame and the first hand wheel bringing pressure to bear on the first vertical support member when the first hand wheel is turned, the second shaft engaged to the frame and the second hand wheel bringing pressure to bear on the second vertical support member when the second hand wheel is turned to secure the double door gate apparatus at a location.

13. A double door gate apparatus, comprising:
a) a frame having a first vertical support member, a second vertical support member, and a horizontal support member, the first and second vertical support members being spaced apart, and the first and second vertical support members engaged to the horizontal support member;
b) a main gate having an outer end and an inner end, the outer end of the main gate mounted to the first vertical support member of the frame on a first pivot axis, the inner end of the main gate swingable to open and close the main gate relative to the frame, the inner end of the main gate being swingable over the horizontal support member of the frame;
c) a second gate having an outer end and an inner end, the outer end of the second gate mounted to the second vertical support member of the frame on a second pivot axis, the inner end of the second gate being swingable to open and close the second gate relative to the frame, the inner end of the second gate being swingable over the horizontal support member of the frame, and the inner end of the second
