Abstract

The present invention relates to a latching device for securing two panels together such as those of storage structures in which an enclosure is secured by means of a door or panel which will remain in a closed position until released. The present latching system is usually used in connection with automobile glove boxes or other compartments which are to be secured for storage of items therein. The latching device has a housing, actuation means and a pawl in communication with a movable retention means. The latching device can be electrically or manually operated.

4. The latch assembly of claim 3, wherein the pawl is mounted to the hook-like shaped member for pivoting, the mounting location being outside of the sidewall from which the hook-like shaped member extends.

5. The latch assembly of claim 4, wherein the hook-like shaped member is bifurcated having a pair of spaced apart hook-shaped flanges.

6. The latch assembly of claim 5, wherein each of the hook-shaped flanges carries a recession, these recessions being juxtaposed, and wherein the pawl has a pair of pivot spindles extending from opposite sides of the pawl, the pawl being snapably mountable into the hook-shaped flange recessions.

7. The latch assembly of claim 1, wherein the locking member carries a collar at a point along the extension thereof.

8. The latch assembly of claim 6, wherein the locking member carries a collar at a point along the extension thereof.

9. The latch assembly of claim 8, wherein said spring positioned inboard of the locking member and operating against the solenoid from which the locking member extends is position inboard of said locking member collar.

10. The latch assembly of claim 9, also including lateral tabs, one each extending from each of the hook-shaped flanges.

11. The latch assembly of claim 10, wherein each of the lateral tabs is positioned on the outboard face of the respective hook-shaped flange.

12. A latch assembly for releasably securing a first member to a second member, said second member having a keeper in a fixed positional relationship therewith, the latch assembly comprising:

an elongate housing having two opposing walls thereto and a hook-like shaped member extending outwardly from an outside of a said wall thereof, said hook-like shaped member being bifurcated having a pair of spaced apart hook-shaped flanges;

a pair of lateral tabs, one each extending from each of the hook-shaped flanges, on an outboard face thereof;

a pawl pivotally attached to said housing and pivotably movable between a closed position and an open position, said pawl engaging said keeper in said closed position;

a spring member biasing said pawl to said open position; and

means positioned within said housing and operating parallel to a longitudinal axis thereof for intercepting the pivotal movement of said pawl for holding said pawl in said closed position;

a spring positioned inboard of said intercepting means and operating to bias the intercepting means to extend outwardly toward said pawl;

wherein said pawl extends outwardly from said housing transversely to said longitudinal axis thereof and in adjacent proximity to said housing hook-like shaped member.

13. The latch assembly of claim 12, wherein the housing includes an opening in a sidewall thereof, the pawl operating though this opening and being mounted for the pivoting movement at a point outside of the sidewall of the housing.

14. The latch assembly of claim 13, wherein the pawl is mounted to the hook-like shaped member for pivoting, the mounting location being outside of the sidewall from which the hook-like shaped member extends.

15. The latch assembly of claim 14, wherein the hook-like shaped member is bifurcated having a pair of spaced apart hook-shaped flanges.

16. The latch assembly of claim 15, wherein each of the hook-shaped flanges carries recession, these recessions being juxtaposed, and wherein the pawl has a pair of pivot spindles extending from opposite sides of the pawl, the pawl being snapably mountable into the hook-shaped flange recessions.

17. The latch assembly of claim 16, wherein said intercepting and holding means includes:

a solenoid supported within said housing and operating parallel to said longitudinal axis thereof; and

a locking member extending from said solenoid parallel to said longitudinal axis of said housing and actuated by said solenoid, said locking member being movable to selectively intercept said pivotably movable pawl.

18. A latch assembly for engaging a keeper, comprising:

an elongate housing having walls and a longitudinal axis and sidewalls thereto and a hook-like shaped member, said hook-like shaped member being connected to one of said walls of said housing, and being bifurcated having a pair of spaced apart hook-shaped flanges;

a pair of lateral tabs, one each extending from each of the hook shaped flanges, on an outboard face thereof;

at least one pawl pivotally attached to said housing and pivotably movable between a first position and a second position, said pawl engaging said keeper in said second position; and

means positioned within said housing and operating parallel to said longitudinal axis thereof for intercepting the pivotal movement of said pawl thereby prohibiting said pawl from pivoting;

wherein said pawl extends outwardly from said housing transversely to said longitudinal axis thereof and in adjacent proximity to said housing hook-like shaped member

wherein said intercepting means includes a solenoid and a locking member; and

a spring positioned to bais said locking member towards said pawl and away from said solenoid.

19. The latch of claim 18, also including a catch bar supported by said housing for translational and pivotal movement, said catch bar being movable between locked and unlocked positions;

wherein said pawl is supported by said housing proximate said hook-like structure, said pawl being movable between a closed keeper engaging position and an open position, said pawl being biased toward said open position, and said pawl having a bottom lug; and

also including a catch bar biasing means for biasing said catch bar toward engagement with said bottom lug; and
