Abstract

A hinge device having a way to detach one hinge member from another includes a fender mounting plate with a pivot pin secured thereto, a hood mounting plate having a pivot pin engaging slot, an elongated pawl having a latch plate engaging end, the pawl secured to the hood mounting plate, a latch plate rotatably secured to the hood mounting plate in a spaced relationship with the elongated pawl where the latch plate has a pawl engaging slot shaped to engage the pawl latch plate engaging end, a pivot pin engaging slot shaped to engage the pivot pin, and a pawl unlock surface that contacts the latch plate engaging end when the elongated pawl is not engaged with the pawl engaging, whereby a user can detach one hinge member from another by withdrawing the elongated pawl, translating one hinge member in relation to the other, and thereby rotating the latch plate, which disengages the latch plate and hood mounting plate from the pivot pin and separates the hinge members.

Claims

1. A hinge device having means to detach one hinge member from another comprising:

a fender mounting plate having a pivot pin secured thereto;

a hood mounting plate having a pivot pin engaging slot;

an elongated pawl having a latch plate engaging end, the pawl slideably secured to the hood mounting plate; and

a latch plate rotatably secured to the hood mounting plate in a spaced relationship with the elongated pawl, the latch plate comprising;

a pawl engaging slot shaped to engage the pawl latch plate engaging end;

a pivot pin engaging slot shaped to engage the pivot pin; and

a pawl unlock surface that contacts the latch plate engaging end of the elongated pawl when the elongated pawl is not engaged with the pawl engaging slot;

whereby a user can detach one hinge member from another by withdrawing the pawl, translating one hinge member in relation to the other, thereby rotating the latch plate, which disengages the latch plate and hood mounting plate from the pivot pin and separates the hinge members.

2. The device of claim 1, the latch plate comprising a stop surface for contacting the latch plate engaging end of the elongated pawl and adapted to prevent the latch plate from rotating when the hinge members are detached.

3. The device of claim 2, the latch plate further comprising a stop engaging surface adapted to engage the stop when the hinge members are detached.

4. The device of claim 3, wherein the pawl engaging slot is adjacent to the latch plate pivot pin engaging slot, the latch plate pivot pin engaging slot is adjacent to the stop engaging surface, the stop engaging surface is adjacent to the pawl unlock surface, and the pawl unlock surface is adjacent to the pawl engaging slot.

5. The device of claim 1, further comprising a return spring secured on a spring first end to the pawl and secured on a spring second end to the hood mounting plate, whereby the pawl is pulled into the pawl engaging slot when the latch plate is rotated into an attached position.

6. The device of claim 1, the pawl further comprising a handle on an end opposite the latch plate engaging end, whereby a user can pull the pawl to disengage the device.

7. The device of claim 1, further comprising a latch plate retaining screw adapted to rotatably secure the latch plate to the hood mounting plate.

8. The device of claim 1, the hood mounting plate comprising a plurality of collinear slots for slidably securing the pawl to the hood mounting plate.

9. The device of claim 8, further comprising pawl mounting screws secured to the pawl corresponding to the hood mounting plate slots.

10. The device of claim 9, further comprising shoulder washers disposed on the pawl mounting screws.

11. A detachable hood mounting system comprising:

a first side hinge assembly comprising;

a first side hood mounting plate having a first side pivot pin engaging slot;

an elongated pawl having a latch plate engaging end, the pawl slidably secured to the hood mounting plate;

a latch plate rotatably secured to the first side hood mounting plate in a spaced relationship with the pawl, the latch plate comprising;

a pawl engaging slot shaped to engage the pawl latch plate engaging end;

a pivot pin engaging slot shaped to engage a pivot pin; and

a pawl unlock surface that contacts the latch plate engaging end when the pawl is not engaged with the slot;

a first side striker pivot pin; and

a first side fender mounting plate to which the first side pivot pin is secured; and

a second side hinge assembly comprising;

a second side hood mounting plate;

a second side pivot pin; and

a second side fender mounting plate.

12. The system of claim 11, the first side hood mounting plate comprising a stop protruding from the plate adapted to prevent the latch plate from rotating when the hinge members are detached.

13. The system of claim 12, the latch plate further comprising a stop engaging surface adapted to engage the stop when the hinge members are detached.

14. The system of claim 13, wherein the pawl engaging slot is adjacent to the latch plate pivot pin engaging slot, the latch plate pivot pin engaging slot is adjacent to the stop engaging surface, the stop engaging surface is adjacent to the pawl unlock surface, and the pawl unlock surface is adjacent to the pawl engaging slot.

15. The system of claim 11, further comprising a return spring secured on a spring first end to the pawl and secured on a spring second end to the first side hood mounting plate, whereby the pawl is pulled into the pawl engaging slot when the latch plate is rotated into an attached position.

16. The system of claim 11, the pawl further comprising a handle on an end opposite the latch plate engaging end, whereby a user can pull the pawl to disengage the device.

17. The system of claim 11, further comprising a latch plate retaining screw adapted to rotatably secure the latch plate to the first side hood mounting plate.

18. The system of claim 11, the first side hood mounting plate comprising a plurality of collinear slots for slidably securing the pawl to the first side hood mounting plate.

19. The system of claim 18, further comprising pawl mounting screws secured to the pawl corresponding to the first side hood mounting plate slots.

20. The system of claim 19, further comprising shoulder washers disposed on the pawl mounting screws.
