Lockable hinge assembly
The present invention relates to a hinge joint mechanism. The hinge joint mechanism comprises a fixed component including a plurality of curved portions and at least one straight portion; a movable component including a plurality of curved portions and a plurality of straight portions; said hinge joint mechanism provides a relative rotation between the two surfaces of the hinge joints to rotate the movable component by a desired amount relative to the fixed component. The hinge joint mechanism of the invention provides a proper sealing in the joints to avoid liquid or any such kind of material to move across it.
1. A lockable hinge assembly comprising:
a first hinge member, the first hinge member comprising an outer convex surface;
a second hinge member hingedly attached to the first hinge member; and
a locking member provided at an attachment of the first hinge member and the second hinge member, the locking member being capable of sliding axially between a locked position and an unlocked position between the first and second hinge members, wherein in the unlocked position, the locking member is in contact with at least one of the first and second hinge members;
wherein in the locked position, the locking member restricts a relative movement of the first hinge member and second hinge members, and wherein in the unlocked position, the first hinge member can move relative to the second hinge member;
wherein the locking member comprises a curved panel, the curved panel providing an inner concave surface and an outer convex surface, wherein the inner concave surface of the curved panel contours against the outer convex surface on the first hinge member; and
wherein at least a portion of one of the first and second hinge members is partially enclosed within the other of the first and second hinge members.
2. The lockable hinge assembly as claimed in claim 1 , wherein the first hinge member and second hinge member join together without the need for a separate interlocking pin.
3. The lockable hinge assembly as claimed in claim 1 , wherein the first hinge member is stationary and the second hinge member is movable.
4. The lockable hinge assembly as claimed in claim 1 , wherein the first hinge member is movable and the second hinge member is stationary.
5. The lockable hinge assembly as claimed in claim 1 , wherein both the first hinge member and the second hinge member are movable.
6. The lockable hinge assembly as claimed in claim 1 , wherein at least a part of the locking member meshes with the first hinge member.
7. The lockable hinge assembly as claimed in claim 1 , wherein at least a part of the locking member meshes with the second hinge member.
8. The lockable hinge assembly as claimed in claim 1 , wherein the locking member is slid either manually or automatically.
