Abstract

A safety gate has a gate frame, a pivotable fence, a latch device and a fence stopper. The gate frame has a base, two side frames and a block formed on the base. The pivotable fence is mounted within the gate frame. One side of the pivotable fence is pivotally mounted within the gate frame by a pivoting element. The latch device has a first pin member and a first latch member respectively having two magnets corresponding to each other. The fence stopper abuts against the block to limit the pivotable fence to be unidirectionally pivotable. The attraction force between the magnets and a restoring force of the pivoting element return the pivotable fence back within the gate frame. The fence stopper and the block abut against each other to avoid the circumstance when the pivotable fence is slammed too hard and the latch device is not securely locked.

Claims

1. A safety gate comprising:

a gate frame having;

a base having;

a top;

two ends; and

a block mounted on the top of the base; and

a first side frame and a second side frame respectively mounted on two locations of the top of the base adjacent to the two ends of the base;

a pivotable fence pivotally mounted within the first side frame, the second side frame and the base, and having;

a first side bar being adjacent to the first side frame;

a second side bar being adjacent to the second side frame and having a top;

multiple intermediate bars mounted between the first side bar and the second side bar; and

a pivoting element mounted on the top of the second side bar, and pivotally mounted on the top of the second side frame; and

a latch device having at least one pin and latch assembly, wherein one of the at least one pin and latch assembly is mounted between the first side frame and the first side bar of the pivotable fence and has a first pin member and a first latch member, the first pin member and the first latch member engage each other and respectively have two magnets, the magnet of the first pin member is adjacent to the magnet of the first latch member, and the magnets of the first pin member and the first latch member attract each other.

2. The safety gate as claimed in claim 1, wherein

the first pin member has a first rod mounted in the first pin member and being extendable beyond one end of the first pin member facing the first side bar and is restorable to the inside of the first pin member, and

the first latch member has a first slot formed in the first latch member, facing the first rod for the first rod to engage the first slot, and having a first bevel surface formed on a bottom wall of the first slot in a vertical direction.

3. The safety gate as claimed in claim 1, wherein the pivoting element has a restoring force pivoting the pivotable fence back within the first side frame and the second side frame, and enables the pivotable fence to be moved up and down within a preset range.

4. The safety gate as claimed in claim 2, wherein the pivoting element has a restoring force pivoting the pivotable fence back within the first side frame and the second side frame, and enables the pivotable fence to be moved up and down within a preset range.

5. The safety gate as claimed in claim 3, wherein the latch device has two pin and latch assemblies, and the other pin and latch assembly has:

a second pin member mounted in the bottom of the pivotable fence, facing the first side frame and having a second rod mounted on and resiliently extendable beyond a side of the second pin member; and

a second latch member mounted on a bottom of the first side frame to align with the second pin member for the second pin member to engage the second latch member.

6. The safety gate as claimed in claim 4, wherein the latch device has two pin and latch assemblies, and the other pin and latch assembly has:

a second pin member mounted in the bottom of the pivotable fence, facing the first side frame and having a second rod mounted on and resiliently extendable beyond a side of the second pin member; and

a second latch member mounted on a bottom of the first side frame to align with the second pin member for the second pin member to engage the second latch member.

7. The safety gate as claimed in claim 5 further comprising a fence stopper, wherein the fence stopper is mounted on a location on the bottom of the pivotable fence corresponding to the block of the gate frame and has two stops respectively mounted on two sides of the pivotable fence, and each stop is pivotable toward the base to abut against the base and the block so as to block the pivotable fence to be unidirectionally pivotable.

8. The safety gate as claimed in claim 6 further comprising a fence stopper, wherein the fence stopper is mounted on a location on the bottom of the pivotable fence corresponding to the block of the gate frame and has two stops respectively mounted on two sides of the pivotable fence, and each stop is pivotable toward the base to abut against the base and the block so as to block the pivotable fence to be unidirectionally pivotable.
