Abstract

An appliance lock includes a housing and a lid movable between an open and closed positions. First and second sliders supported for movement by the housing. A striker is attachable to the other of the appliance body and lid. The striker is connectable with the housing upon movement of the lid to the closed position. The striker has a first portion for engaging and moving the first slider from a first position to a second position upon lid movement to the closed position. The striker has a second portion for engaging and moving the second slider from a first position to a second position upon lid movement to the closed position. The first and second sliders being in the second positions enables activation of the appliance. Structure minimizes the ability to move the first and second sliders to the second position by substantially anything but the striker.

First claim

What is claimed is:

1. An appliance lock comprising:
a housing attachable to one of an appliance body and a lid that is movable relative to the body between an open position and a closed position;
a first slider supported for movement by the housing;
a second slider supported for movement by the housing;
a striker attachable to the other of the appliance body and lid and connectable with housing upon movement of the lid to the closed position, the striker having a first portion for engaging and moving the first slider from a first position to a second, different position located along a moving path from the first position upon movement of the lid to the closed position, the striker having a second portion for engaging and moving the second slider from a first position to a second, different position located along the same moving path as the first slider from the first position upon movement of the lid to the closed position;
a switch assembly for electrical connection to a controller;
wherein the switch assembly interfaces with the first and second sliders when the first and second sliders being in the second position, providing indication that the lid is closed; and
wherein the first and second sliders being in the second positions provides indication that the lid is closed; and
structure to minimize the ability to simultaneously move the first and second sliders to the second position by substantially anything but the striker and thereby prevent activation of the appliance.

2. The appliance lock of claim 1 wherein the structure includes a separator attached to the housing and located between the sliders and wherein the first and second portions of the striker span the separator.

3. The appliance lock of claim 1 wherein the structure includes the sliders being spaced apart a predetermined distance and wherein the first and second portions of the striker span the predetermined distance.

4. The appliance lock of claim 1 further including a switch operatively connected to at least one of the first and second sliders to prevent activation of the appliance when the first and second sliders are in the first positions.

5. The appliance lock of claim 1 further including a third slider operably connected the first slider to move in unison with the first slider to the second position.

6. The appliance lock of claim 1 further including a mechanism to retain a slider in the second position and thereby blocking movement of the lid from the closed position when the appliance is activated.

7. The appliance lock of claim 1 wherein movement of the first and second sliders is reciprocally linear.

8. The appliance lock of claim 1 wherein the first portion of the striker engages only the first slider and the second portion of the striker engages only the second slider.

9. An appliance lock comprising:
a housing attachable to one of an appliance body and a lid that is movable relative to the body between an open position and a closed position;
a first slider supported for movement by the housing;
a second slider supported for movement by the housing;
a striker attachable to the other of the appliance body and lid and connectable with the housing upon movement to the lid to the closed position, the striker having a first portion for engaging and moving only the first slider from a first position to a second, different position located along a moving path from the first position upon movement of the lid to the closed position, the striker having a second portion for engaging and moving only the second slider from a first position to a second, different position located along the same moving path as the first slider from the first position upon movement of the lid to the closed position;
a switch assembly for electrical connection to a controller;
wherein the switch assembly interfaces with the first and second sliders when the first and second sliders being in the second position, providing indication that the lid is closed; and
wherein the first and second sliders being in the second positions provides indication that the lid is closed; and
a separator attached to the housing and located between the first and second sliders, the first and second portions of the striker span the separator, the separator minimizes the ability to simultaneously move the first and second sliders to the second position by substantially anything but the striker and thereby prevent activation of the appliance when the lid is not closed position.

10. The appliance lock of claim 9 further including a switch operatively connected to at least one of the first and second sliders to prevent actuation of the appliance when the first and second sliders are in the first positions.

11. The appliance lock of claim 10 further including a mechanism to retain a slider in the second position and thereby blocking movement of the lid from the closed position when the appliance is activated.

12. The appliance lock of claim 9 wherein the second slider is position within first slider.

13. The appliance lock of claim 9 wherein movement of the first and second sliders is reciprocally linear.

14. An appliance lock comprising:
a housing attachable to one of an appliance body and a lid that is movable relative to the body between an open position and a closed position;
a first slider supported for movement by the housing;
a second slider supported for movement relative to the housing in unison with the first slider;
a third slider supported for movement relative to the housing; and
a striker attachable to the other of the appliance body and lid and operatively connectable with the housing upon movement to the lid to the closed position, the striker having a first portion for engaging and moving only the second slider from a first position to a second, different position located along a moving path from the first position upon movement of the lid to the closed position, the striker having a second portion for engaging and moving only the third slider from a first position to a second, different position located along the same moving path as the second slider from the first position upon movement of the lid to the closed position;
a switch assembly for electrical connection to a controller;
wherein the switch assembly interfaces with the first and third sliders when the first and third sliders being in the second position, providing indication that the lid is in closed position.

15. The appliance lock of claim 14 wherein the second and third sliders are spaced apart a predetermined distance, the first and second portions of the striker span the predetermined distance, the spaced apart sliders minimize the ability to move the second and third sliders to the second position by substantially anything but the striker and thereby prevent activation of the appliance when the lid is not in the closed position.

16. The appliance lock of claim 15 further including a separator and located between the second and third sliders, the first and second portions of the striker span the separator, the separator minimizes the ability to simultaneously move the second and third sliders to the second position by substantially anything but the striker and thereby prevent activation of the appliance when the lid is not closed position.

17. The appliance lock of claim 14 further including a switch operatively connected to at least one of the sliders the sliders to prevent activation of the appliance when the second and third sliders are in the first positions.

18. The appliance lock of claim 14 further including a mec
