Abstract
The invention generally relates to a latch apparatus having a locking live bolt. One embodiment of the invention is a latch apparatus having a housing with opposed plates that are spaced apart and secured to each other by support arms formed from the plates. A live bolt of the apparatus is slidably mounted in the housing and horizontally actuated between an extended and a retracted position. A live bolt hub is mounted in the housing and actuates the live bolt. A slide, actuated by a rotatable cam, is mounted in the housing and moves vertically between a first position and a second position. In the first position the slide is disengaged from the live bolt, and in the second position the slide locks the live bolt in an extended position.
Claims21
A latch apparatus, comprising;
- a housing having opposed plates, the plates being spaced apart and secured to each other by support arms;
- a live bolt slidably mounted in the housing and horizontally actuated between an extended and a retracted position;
- a live bolt hub mounted in the housing and contacting the live bolt to actuate the live bolt between the extended and retracted positions;
- a slide mounted in the housing and moving vertically between a first position disengaged from the live bolt and a second position engaging the live bolt, the slide including a flexible arm, the flexible arm having a first end integrally formed with the slide and a second end defining a cam engaging surface;
- and
- a cam arranged and configured to engage the cam engaging surface to actuate the slide between the first position and the second position;
- wherein in the first position, the live bolt is free to move between the extended and retracted positions, and in the second position, the slide locks the live bolt in the extended position.
A latch apparatus, comprising;
- opposed plates secured to each other, the plates forming a housing;
- a live bolt slidably mounted in the housing and horizontally actuated between an extended and a retracted position;
- a slide mounted in the housing and moving vertically between a first position disengaged from the live bolt, and a second position engaging the live bolt to lock the live bolt in the extended position, the slide comprising a flexible arm with a cam engaging surface;
- and
- a cam permanently mounted between the opposed plates and configured to actuate the slide between the first position and the second position, the cam including a cam arm defining a generally curved cam surface;
- wherein the cam engages the cam engaging surface to bend the flexible arm while actuating the slide between the first and second positions.
A latch apparatus, comprising;
- a housing having opposed plates, the plates being spaced apart and secured to each other by support arms;
- a live bolt slidably mounted in the housing and horizontally actuated between an extended and a retracted position;
- a live bolt hub mounted in the housing and contacting the live bolt to actuate the live bolt between the extended and retracted positions;
- a slide mounted in the housing vertically above the live bolt hub and movable vertically between a first position disengaged from the live bolt and a second position engaging the live bolt, the slide including a contact arm, wherein the contact arm is flexible, is flexibly formed with the slide, and is coupled to the slide at only one end of the contact arm;
- arm
- a cam arranged and configured to engage the contact arm and move the contact arm towards the slide during rotation of the cam thereby actuating the slide between the first position and the second position, the cam being positioned in the housing vertically above the live bolt hub;
- wherein in the first position, the live bolt is free to move between the extended and retracted positions, and in the second position, the slide locks the live bolt in the extended position.
