Abstract
A double-door lock assembly includes a first lock and a second lock which are mounted to a first door and a second door, respectively. The first lock includes a first rotary member, a first magnetic member and a linkage member. The second lock includes a second rotary member having a driving portion and a second magnetic member, The first and second rotary members can be driven to rotate together to open or close the first and second doors simultaneously when the first and second magnetic members are attracted to each other and the driving portion on the second rotary member contacts against the linkage member on the first rotary member.
Claims23
A lock assembly for operating a first door and a second door simultaneously or individually, the lock assembly comprising:
- a first lock designed to be mounted to the first door and including a first handle set, a first rotary member rotated by the first handle set, at least one first magnetic member and a linkage member, the at least one first magnetic member and the linkage member are disposed on and moved with the first rotary member, the linkage member is movably disposed in an accommodation hole of the first rotary member and able to be moved into or protruded from the accommodation hole, a first end of the linkage member has a blocking surface;
- and
- a second lock designed to be mounted to the second door and including a second handle set, a second rotary member rotated by the second handle set, at least one second magnetic member and a driving portion, the at least one second magnetic member and the driving portion are disposed on and moved with the second rotary member, wherein when the at least one first magnetic member and the at least one second magnetic member are attracted to each other and the linkage member is protruded from the accommodation hole, the driving portion contacts against the blocking surface of the linkage member such that the first and second rotary members are able to be rotated simultaneously.
A lock assembly for operating a first door and a second door simultaneously or individually, the lock assembly comprising:
- a first lock designed to be mounted to the first door and including a first handle set, a first rotary member rotated by the first handle set and a linkage member disposed on and moved with the first rotary member, the linkage member is moveably disposed in an accommodation hole of the first rotary member and able to be moved into or protruded from the accommodation hole, a first end of the linkage member has a blocking surface and an inclined guide surface located on different sides of the first end;
- and
- a second lock designed to be mounted to the second door and including a second handle set, a second rotary member rotated by the second handle set and a driving portion disposed on and moved with the second rotary member, wherein the first and second rotary members are able to be rotated simultaneously when the driving portion contacts against the blocking surface of the linkage member protruded from the accommodation hole, and wherein the first and second rotary members are able to be separated from each other when the driving portion contacts against the inclined guide surface of the linkage member protruded from the accommodation hole to push the linkage member into the accommodation hole.
