Handrail locking mechanism
View Patent ↗A locking mechanism associated with a handrail is provided. A pair of slots is provided on opposite side surfaces of the housing. Each of the side surfaces is adjacent to the side open end. A bracket is affixed to any one of the side surface of the housing. A locking member is pivotally coupled to the bracket. The first arm of the locking member is configured to selectively engage with the pair of slots to retain the handrail in the upright position. On exerting a force in an upward direction on a second arm of the locking member the first arm is selectively released from the pair of slots to allow the handrail to move from an upright position to a collapsed position.
1. A locking mechanism associated with a handrail, the locking mechanism comprising:
a housing configured to receive the handrail partially therein, the housing having a top open end configured to accommodate the handrail in an upright position, the housing having a side open end configured to accommodate the handrail in a collapsed position;
a pair of slots provided on opposite side surfaces of the housing, wherein each of the side surfaces is adjacent to the side open end;
a bracket affixed to any one of the side surface of the housing; and
a locking member pivotally coupled to the bracket, the locking member comprising:
a first arm configured to selectively engage with the pair of slots to retain the handrail in the upright position, wherein the first arm extends in a first direction; and
a second arm attached to the first arm, wherein the second arm extends in a second direction, the second direction being parallel to and opposite to the first direction, such that on exerting a force in an upward direction on the second arm, the second arm is configured to selectively release the first arm from the pair of slots to allow the handrail to move from the upright position to the collapsed position.
2. The locking mechanism of claim 1 , wherein the locking mechanism is positioned at a base portion of the handrail.
3. The locking mechanism of claim 1 , wherein a length of the first arm is greater than a width of the housing, such that the first arm is configured to engage with the pair of slots.
4. The locking mechanism of claim 1 , wherein the bracket is positioned on the side surface of the housing having one of the pair of slots.
5. The locking mechanism of claim 1 , wherein the locking member includes a slot provided vertically for pivotally coupling the locking member with the bracket, such that the locking member is configured to move in a vertically upward direction along the slot based on the exertion of the force.
6. The locking mechanism of claim 1 , wherein a gripping surface is provided on an inner facing side of the second arm.
7. The locking mechanism of claim 1 further comprising a base plate coupled to a bottom portion of the housing, the base plate configured to attach the locking mechanism to a surface.
8. The locking mechanism of claim 1 , wherein the pair slots and the bracket are provided on an upper portion of the housing.
9. The locking mechanism of claim 1 , wherein the housing has a C shaped cross section.
10. A handrail assembly comprising:
a handrail; and
a locking mechanism associated with the handrail, the locking mechanism comprising:
a housing configured to receive the handrail partially therein, the housing having a top open end configured to accommodate the handrail in an upright position, the housing having a side open end configured to accommodate the handrail in a collapsed position;
a pair of slots provided on opposite side surfaces of the housing, wherein each of the side surfaces is adjacent to the side open end;
a bracket affixed to any one of the side surface of the housing; and
a locking member pivotally coupled to the bracket, the locking member comprising:
a first arm configured to selectively engage with the pair of slots to retain the handrail in the upright position, wherein the first arm extends in a first direction; and
a second arm attached to the first arm, wherein the second arm extends in a second direction, the second direction being parallel to and opposite to the first direction, such that on exerting a force in an upward direction on the second arm, the second arm is configured to selectively release the first arm from the pair of slots to allow the handrail to move from the upright position to the collapsed position.
11. The handrail assembly of claim 10 , wherein the locking mechanism is positioned at a base portion of the handrail.
12. The handrail assembly of claim 10 , wherein a length of the first arm is greater than a width of the housing, such that the first arm is configured to engage with the pair of slots.
13. The handrail assembly of claim 10 , wherein the bracket is positioned on the side surface of the housing having one of the pair of slots.
14. The handrail assembly of claim 10 , wherein the locking member includes a slot provided vertically for pivotally coupling the locking member with the bracket, such that the locking member is configured to move in a vertically upward direction along the slot based on the exertion of the force.
15. The handrail assembly of claim 10 , wherein a gripping surface is provided on an inner facing side of the second arm.
16. The handrail assembly of claim 10 further comprising a base plate coupled to a bottom portion of the housing, the base plate configured to attach the locking mechanism to a surface.
17. The handrail assembly of claim 10 , wherein the pair slots and the bracket are provided on an upper portion of the housing.
18. The handrail assembly of claim 10 , wherein the housing has a C shaped cross section.
19. The handrail assembly of claim 10 , wherein the handrail has at least one of a rectangular, a square, and a circular cross section.
20. A machine comprising:
a power source;
a frame; and
a handrail assembly attached to the frame, the handrail assembly comprising:
a handrail; and
a locking mechanism associated with the handrail, the locking mechanism comprising:
a housing configured to receive the handrail partially therein, the housing having a top open end configured to accommodate the handrail in an upright position, the housing having a side open end configured to accommodate the handrail in a collapsed position;
a pair of slots provided on opposite side surfaces of the housing, wherein each of the side surfaces is adjacent to the side open end;
a bracket affixed to any one of the side surface of the housing; and
a locking member pivotally coupled to the bracket, the locking member comprising:
a first arm configured to selectively engage with the pair of slots to retain the handrail in the upright position, wherein the first arm extends in a first direction; and
a second arm attached to the first arm, wherein the second arm extends in a second direction, the second direction being parallel to and opposite to the first direction, such that on exerting a force in an upward direction on the second arm, the second arm is configured to selectively release the first arm from the pair of slots to allow the handrail to move from the upright position to the collapsed position.
