Lock for frame

A display apparatus including

• a screen and
• a frame system supporting the screen, the frame system having a plurality of frame members, a hinge coupling two of the frame members together, and a lock positioned to block relative movement of the frame members, the lock including first and second interactive members, the first interactive member having a key, and the second interactive member having a key-receiving portion that receives the key of the first interactive member to block relative movement of the frame members when the key is positioned in the key-receiving portion and to permit relative movement of the frame members when the key is spaced apart from the key-receiving portion.

A display apparatus including

• a screen and
• a frame system supporting the screen, the frame system having at least first and second frame members, a hinge coupling the first and second frame members together, and a lock positioned to block relative movement of the first and second frame members, the hinge including a first hinge member, a second hinge member pivotally coupled to the first hinge member, a third hinge member, and a fourth hinge member pivotally coupled to the third hinge member, the first and third hinge members being rigidly coupled to the first frame member, the second and fourth hinge members being rigidly coupled to the second frame member, the second hinge member being positioned between the first hinge member and the second frame member, and the third hinge member being positioned between the fourth hinge member and the second frame member.

A display apparatus including:

• a screen;
• and
• a frame system supporting the screen, the frame system having a plurality of frame members, a hinge coupling two of the frame members together, and a lock positioned to block movement of the frame members coupled together by the hinge, the frame members coupled together by the hinge cooperating to define a longitudinal axis and a transverse profile, at least a portion of the lock being positioned within the transverse profile, the lock including first and second lock members that move relative to one another to permit the frame members to move relative to one another, a portion of the first lock member being positioned within the transverse profile and a portion of the first lock member being positioned outside of the transverse profile, at least one of the frame members coupled together by the hinge being tubular and having an outer wall, two ends, and an aperture positioned between the two ends, at least one of the first and second lock members being movable relative to the other lock member due to force applied to the lock, the force being transmitted through the aperture.

A display apparatus including:
