Front pull latch
A latch that can be unlatched with a force exerted on a front handle of a drawer or other enclosure. The latch includes an end cap that interacts with a cam surface of a body and, upon doing so, disengages the catch from an opening on a strike plate or cabinet body. When the catch is disengaged, the latch can allow for the opening of the enclosure. The latch therefore allows for a simple forward motion to open and close the latch, and further allows the latch to be used with many different enclosures.
1. A latch for an enclosure including an opening, the latch comprising:
an end cap having an end cap portion and a first cam surface;
a handle coupled to the end cap and configured to rotate the end cap;
a body having a body cam surface that engages the end cap portion to cause the body to move linearly inwardly when the end cap portion abuts the body cam surface, the body further includes a catch that is adapted to engage or disengage the opening based on linear movement of the body;
a spring adapted to bias the body in an outwardly direction; and
a holder adapted to receive the body and having an abutment that is adapted to receive the spring to bias the body in the outwardly direction, the holder includes a second cam surface that is adapted to engage the first cam surface when the end cap is rotated.
2. The latch of claim 1 , wherein the body further includes an extension adapted to receive the spring.
3. The latch of claim 2 , wherein the extension is rod shaped and is adapted to be inserted through the spring along a central axis of the spring.
4. The latch of claim 1 , wherein the end cap includes a tab adapted to prevent lateral movement of the end cap, the holder includes an aperture adapted to receive the tab, and the tab is movably disposed in the aperture when the end cap is rotated.
5. The latch of claim 1 , wherein the abutment includes a recess that is adapted to receive the spring.
6. The latch of claim 1 , wherein the end cap includes a protrusion that is adapted to couple to the enclosure.
7. An enclosure that is adapted to open and close, the enclosure comprising:
a latch including;
an end cap having an end cap portion and a first cam surface;
a body having a body cam surface that engages the end cap portion to cause the body to move linearly inwardly when the end cap portion abuts the body cam surface, the body further includes a catch that is adapted to engage or disengage an opening of the enclosure based on linear movement of the body;
a spring that is adapted to bias the body in an outwardly direction; and
a holder that is adapted to receive the body and having an abutment that is adapted to receive the spring to bias the body in the outwardly direction, the holder includes a second cam surface that is adapted to engage the first cam surface when the end cap is rotated;
a handle coupled to the latch at the end cap; and
an enclosure body that is adapted to receive the handle and the latch.
8. The enclosure of claim 7 , wherein the body further includes an extension that is adapted to receive the spring.
9. The enclosure of claim 8 , wherein the extension is rod shaped and is adapted to be inserted through the spring along a central axis of the spring.
10. The enclosure of claim 7 , wherein the end cap includes a tab that is adapted to prevent lateral movement of the end cap, the holder includes an aperture that is adapted to receive the tab, and the tab is movably disposed within the aperture during rotation of the end cap.
11. The enclosure of claim 7 , wherein the abutment includes a recess that is adapted to receive the spring.
12. The enclosure of claim 7 , wherein the end cap includes a protrusion that couples to the enclosure body.
13. The enclosure of claim 7 , wherein the end cap is coupled to the handle and movement of the handle causes rotation of the end cap.
14. The enclosure of claim 13 , wherein movement of the handle causes the end cap portion to abut the body cam surface to cause the body to move linearly inwardly to disengage the catch from the opening.
15. A method of allowing an enclosure to be opened, comprising:
providing a latch including an end cap having an end cap portion and a first cam surface, a body having a body cam surface that engages the end cap portion to cause the body to move linearly inwardly when the end cap portion abuts the body cam surface, the body further including a catch that is adapted to engage or disengage an opening of the enclosure based on linear movement of the body, a spring that is adapted to bias the body in an outwardly direction, and a holder that is adapted to receive the body and having an abutment for that is adapted to receive the spring to bias the body in the outwardly direction, the holder including a second cam surface that is adapted to engage the second cam surface when the end cap is rotated;
rotating a handle coupled to the end cap;
disengaging the catch from the opening in response to the rotation of the handle.
