Storage cabinet with latching mechanism
View Patent ↗A storage cabinet having a latching mechanism that can be unlatched by the use of either an upper actuator or a lower actuator is provided. The upper actuator may comprise a hand knob while the lower actuator may comprise a foot pedal. Thus, if an operator has his arms full and wants to open the doors of the cabinet, he can simply do so by actuating the foot pedal. Alternately, the doors of the cabinet may be opened by actuating the hand knob. This design affords the operator much flexibility in accessing the storage cabinet. A storage cabinet with a latching mechanism that is protected from damage under abusive conditions is also provided.
1. A latching mechanism for a storage cabinet comprising:
a top and bottom plate assembly comprising a top plate and a bottom plate;
a middle plate positioned between the top plate and the bottom plate;
an upper actuator operatively connected to the middle plate; and
a lower actuator operatively connected to the top and bottom plates;
wherein both actuators operate independently of each other to unlatch the latching mechanism.
2. The latching mechanism of claim 1 further comprising at least one connecting rod extending between the top plate and the bottom plate, thereby operatively connecting the top and bottom plates together.
3. The latching mechanism of claim 1 wherein the top plate and the bottom plate each comprise at least one set of protruding fingers.
4. The latching mechanism of claim 3 further comprising a rod engaged with each set of protruding fingers.
5. The latching mechanism of claim 1 further comprising a pair of rails slidably engaged with lateral edges of the latching mechanism to enable the latching mechanism to slide between a latched position and an unlatched position.
6. The latching mechanism of claim 1 wherein the upper actuator comprises a hand knob.
7. The latching mechanism of claim 1 wherein the lower actuator comprises a foot pedal.
8. The latching mechanism of claim 1 wherein the upper actuator is operated by hand.
9. The latching mechanism of claim 1 wherein the lower actuator is operated by foot.
10. A storage cabinet comprising:
a cabinet, the cabinet including at least one door;
a plurality of latches mounted onto the at least one door;
a latching mechanism mounted onto the cabinet for engaging the latches, the latching mechanism comprising a top plate, a middle plate, and a bottom plate, the middle plate being positioned between the top plate and the bottom plate;
an upper actuator operatively connected to the middle plate; and
a lower actuator operatively connected to the top and bottom plates;
wherein both actuators operate independently of each other to unlatch the latching mechanism of the storage cabinet.
11. The storage cabinet of claim 10 further comprising at least one connecting rod extending between the top plate and the bottom plate, thereby operatively connecting the top and bottom plates together.
12. The storage cabinet of claim 10 wherein the top plate and the bottom plate each comprise at least one set of protruding fingers.
13. The storage cabinet of claim 12 further comprising a rod engaged with each set of protruding fingers, each rod engaging one of said latches when the at least one door is in a latched position.
14. The storage cabinet of claim 10 further comprising a pair of rails slidably engaged with lateral edges of the latching mechanism to enable the latching mechanism to slide between a latched position and an unlatched position.
15. The storage cabinet of claim 14 further comprising a locking mechanism for preventing movement of the latching mechanism to the unlatched position.
16. The storage cabinet of claim 10 wherein each latch includes a slot for engaging a rod, a ramp portion, and a tang portion.
17. The storage cabinet of claim 10 wherein the upper actuator comprises a hand knob.
18. The storage cabinet of claim 10 wherein the lower actuator comprises a foot pedal.
19. A storage cabinet comprising:
a cabinet, the cabinet including at least one door;
a plurality of latches mounted onto the at least one door;
a latching mechanism mounted onto the cabinet for engaging the latches, the latching mechanism comprising a top plate, a middle plate, and a bottom plate;
two rails positioned along the edges of the latching mechanism;
a plurality of rods, each rod engaging one of said latches when the at least one door is in a latched position;
an upper actuator operatively connected to the middle plate; and
a lower actuator operatively connected to the top and bottom plates;
wherein when the upper actuator is moved upwardly, the middle plate slides along the rails and moves upwardly, causing the top and bottom plates to move upwardly, thereby lifting the rods out of engagement with the latches and placing the latching mechanism in an unlatched position; and
wherein the lower actuator is unaffected by the upward movement of the upper actuator.
