Abstract
A combination lock is provided, the combination lock having a rotary latch configured for rotation between a locked position and an unlocked position, the rotary latch rotating in a first plane; and a bolt configured for movement between a first position and a second position along a second plane the second plane being oriented at a different location than the first plane, the bolt engaging the rotary latch in the first position such that rotation of the rotary latch from the locked position to the unlocked position is prevented.
Claims19
A combination lock, comprising:
- a rotary latch configured for rotation between a locked position and an unlocked position, the rotary latch being rotatably secured to a housing of the combination lock, wherein the rotary latch rotates in a first plane, the rotary latch has an opening at one end and a shoulder portion at an opposite end each being aligned with each other and in the first plane;
- and
- a bolt configured for movement between a first position and a second position along a second plane in response to operation of the combination lock, the second plane being oriented at a different location than the first plane, the bolt further comprising a portion configured to engage the shoulder portion of the rotary latch when the rotary latch is in the locked position and the bolt is in the first position such that rotation of the rotary latch from the locked position to the unlocked position is prevented by the portion of the bolt engaging the shoulder portion of the rotary latch and wherein the bolt is movably mounted to the housing, wherein the housing further comprises an extended housing portion extending from the housing wherein the housing and the extended housing each define an interior area, the extended housing portion surrounding and enclosing a shaft the rotary latch rotates on.
A combination lock, comprising:
- a rotary latch configured for rotation between a locked position and an unlocked position, the rotary latch being rotatably secured to a housing of the combination lock, wherein the rotary latch rotates in a first plane, the rotary latch has an opening at one end and a shoulder portion at an opposite end each being aligned with each other and in the first plane;
- and
- a bolt configured for movement between a first position and a second position along a second plane in response to operation of the combination lock, the second plane being oriented at a different location than the first plane, the bolt further comprising a portion configured to engage the shoulder portion of the rotary latch when the rotary latch is in the locked position and the bolt is in the first position such that rotation of the rotary latch from the locked position to the unlocked position is prevented by the portion of the bolt engaging the shoulder portion of the rotary latch and wherein the bolt is movably mounted to the housing, wherein bolt further comprises, a first leg portion and a second portion, the first leg portion connecting the portion and the second portion of the bolt and wherein the portion and the second portion are each separated from each other by the first leg portion and the second portion is located in a plane parallel to the second plane and wherein the first leg portion is located in a plane parallel to the first plane, wherein the shoulder portion rotates within an interior portion of an enclosed extended portion of the housing of the combination lock and wherein a portion of the rotary latch extends outwardly from an opening in the extended housing portion of the combination lock, wherein the extended housing portions extends away from a sidewall of the housing.
A method of locking and unlocking a combination lock, comprising:
- rotatably mounting a rotary latch to a housing of the combination lock for rotation between a locked position and an unlocked position, wherein the rotary latch rotates in a first plane, the rotary latch having an opening at one end and a shoulder portion at an opposite end each being aligned with each other and in the first plane;
- and
- movably mounting a bolt to the housing of the combination lock for movement between a first position and a second position along a second plane in response to operation of the combination lock, the second plane being oriented at a different location than the first plane, the bolt further comprising a portion configured to engage the shoulder portion of the rotary latch when the rotary latch is in the locked position and the bolt is in the first position such that rotation of the rotary latch from the locked position to the unlocked position is prevented by the portion of the bolt engaging the shoulder portion of the rotary latch, wherein the housing further comprises an extended housing portion extending from the housing wherein the housing and the extended housing portion each define an interior area, the extended housing portion surrounding and enclosing a shaft the rotary latch rotates on.
