Gate Latch Preventing Rotation Until Lifted
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety gates often compromise security due to automatic closure features that allow rotational movement, making it easier for children or pets to open the gate, and lack effective mechanisms to prevent rotation until the gate is lifted.
Innovation Solution
A gate latch system with a latch bolt and operator that slide in different directions, combined with a hinge arrangement that locks the gate in a closed position, requiring the gate barrier to be lifted before allowing rotation, enhancing security by preventing rotational movement until the gate is opened vertically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional safety gates employ automatic closure features that allow rotational movement, then the gate can be easily opened by children or pets, but the ease of operation for adults is improved
Solution Approach 1:
The latch system dynamically changes its state based on gate position. When the gate is in the closed position, the latch bolt is engaged with the latch receptacle, preventing rotation. When the gate is lifted to the open position, the latch bolt disengages from the receptacle, allowing rotational movement. This dynamic behavior resolves the contradiction by providing security when closed and ease of operation when opening.
Solution Approach 2:
The hinge arrangement is configured to require lifting the gate barrier to an upper position before the latch bolt can disengage from the receptacle. This preliminary action of lifting必须先 occur before the gate can rotate open, ensuring that children or pets cannot simply push the gate open while maintaining easy operation for adults who can perform the lifting motion.
2Ease of operation
If the gate allows rotational movement without lifting, then opening is simpler, but security against children or pets is reduced
Solution Approach 1:
The latch system applies preliminary anti-action by preventing rotational movement when the gate is in the closed position through engagement of the latch bolt with the latch receptacle. This counteracts any attempt by children or pets to push the gate open by applying resistance in the form of the engaged latch, while still allowing simple lifting motion for proper opening.
3Device complexity
If the latch bolt and operator slide in the same direction, then the mechanism is simpler, but the ability to prevent rotation until lifting is reduced
Solution Approach 1:
The latch operator is configured to slide in a first direction while the latch bolt slides in a second direction that is different from the first direction. This dimensional change in the sliding directions allows the operator to move independently from the bolt, enabling the operator to disengage from the bolt before the gate rotates, thereby preventing rotation until lifting occurs while maintaining reasonable mechanism simplicity.

AI summary
A gate includes a gate barrier and a hinge configured to allow the gate barrier to rotate about a rotation axis and translate along the rotation axis. The gate may include a gate latch coupled to the gate barrier, where the gate latch includes a latch bolt and a latch operator. The latch bolt may be configured to slide between an engaged position and a disengaged position in a first direction (e.g., a horizontal direction). The latch operator may be engaged with the latch bolt and configured to slide between a locking position and an unlocking position in a second, different direction (e.g., an inclined direction).
