Description: RATCHETING PAWL LATCH BACKGROUND OF THE INVENTION 1. Field of Invention The present invention relates to the field of latch assemblies. 2. Brief Description of the Prior Art Latch assemblies are relied on in many applications for securing items, such as panels, together. For example, containers, cabinets, closets, compartments and the like may be secured with a latch. An important use for latches is in the automotive field, where there is a desire and need to access automotive compartments, such as, for example, the trunk or passenger compartments of vehicles, as well as interior compartments such as a glove box. Various latches for panel closures have been employed where one of the panels such as a swinging door or the like is to be fastened or secured to a stationary panel or compartment body. The prior art devices generally utilize a locking member which is spring loaded externally by one or more separately provided torsion springs. For example, some prior art devices rely upon a lock which comprises rigid metal parts and requires additional biasing members for operation of the assembly. SUMMARY OF THE INVENTION The present invention relates to a latching system 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. An example of a use of the present latching system is in connection with automobile glove boxes or other compartments which are to be secured for storage of items therein. The present invention provides a novel ratcheting pawl latch assembly with a spring locking member which provides the locking member with its own internal spring force when the locking member is deflected by an actuating lever. The actuating lever can be provided in the form of a handle or paddle. The spring locking member enables a force from a handle of the latch assembly to be transmitted to a pawl which selectively engages and disengages a keeper member. When the keeper member engages the pawl, the pawl is rotated until the locking member slips in behind it. The pawl is provided with a torsional spring member which causes a force load from the spring member to be supplied to the pawl. When the paddle is rotated or swingably moved away from the panel surface to which it is attached, the spring locking member is engaged and is lowered and retracted out of the way of the pawl. The pawl is disengaged from the keeper with the actuation of the paddle, which causes the spring locking member to release from its engagement with the pawl, whereupon the torsional pawl spring member which provides a force load to the pawl, releases its force load to return the pawl to its unlocked position away from engagement with the keeper. The keeper wire is thereby disengaged and the paddle or handle is reset with a spring loading mechanism to its original position. The present invention also provides a locking mechanism in which a key can selectively lock and unlock the latch assembly. In addition, the present invention also provides a means whereby the handle or paddle can be offset from the pawl and locking member. This offers greater flexibility for selecting a location for the latch and for greater alternative placements when utilizing this latch as described herein. It is a principal object of the present invention to provide a novel latch assembly which is selectively engagable with a keeper member, and includes a spring locking member which is spring-loaded with its own spring force for engaging and releasing a pawl from a keeper member when a handle is actuated. It is another object of the present invention to provide a locking member which is comprised of spring steel or plastic. Another object of the present invention is to provide a lock which can be operated by a key or other operator, such as radio, infrared, electronic or other means, which selectively engages the locking member against movement.

The second slot 27 extends through the housing body 24, and is generally perpendicular in relation to the first slot 26, as shown in the rear perspective view of the latch assembly of Fig. 2. The latch assembly 10 also includes a pawl 28 shown pivotally connected to the latch housing 12 with suitable attachment means such as the pawl pivot members 29,30 which are provided extending outwardly from the pawl 28 at opposite sides thereof. The pivot members 29, 30 can also be provided as a single pivot member extending through the pawl 28. A pair of annular portions 31 are provided on the pawl pivot members 29,30. The annular portions 31 may be provided integral with the pawl pivot members 29,30 or can be separately provided in the form of rings or washer members which can be provided on the pawl pivot member 29,30. The annular portions 31 facilitate centering of the pawl 28 within the housing 12 in the centering slots 45a, 45b provided in the housing 12 (Fig. 1) . The pawl 28 is installed onto the housing 12 by snap-fit placement of the pawl pivot members 29,30 into the pawl pivot recesses 32,33 disposed in the housing 12. A pair of guide slots 34,35 is provided on the housing leading from the edge of the housing to the pawl pivot recesses 32,33 for guiding the pawl pivot members 29,30, in the direction of arrow "b" into the pawl pivot recesses 34,35. As shown in Fig. 1, the pawl 28 is provided having a body portion 36 with a pair of pawl pivot members 29,30 extending therefrom. The pawl 28 has a locking engagement portion 37 and is provided with a pawl slot 38 to retain the keeper member 100 shown in Fig. 3. Preferably the keeper member 100 is attached to the stationary panel or compartment (not shown) at a position such that when the swinging panel to which the latch assembly 10 is attached is rotated to engage the keeper member 100, the keeper member 100 will be below the arm portion of the upper flange 25 for engagement with the pawl 28. The pawl 28 is also shown having an arm portion 39 extending from the pawl body 36. A pawl torsional spring 40 is shown installed on the pawl 28, and having downwardly extending tail portions 41,42 and arms 43,44 extending vertically therefrom. The vertical spring arms 43,44 extend from the respective coil portions 46 of the torsional spring 40 and connect to form a slot 47 for receiving the pawl arm 39 therein for engagement therewith. The paddle 11 in Fig. 1 is shown having an actuation arm 48 extending rearwardly therefrom and a paddle retaining pin 49 extending rearwardly therefrom. Extending from the housing body 24 is a spring retaining socket 50 which is disposed in the area of the paddle retaining pin 49. A paddle compression spring 51 is installed on the retaining pin 49 and is held in part by the socket 50, as shown by arrow n c." The spring 51 provides a bias when the handle 11 is lifted so that after actuation takes place the handle 11 is returned to its original position by the force of the compression spring 51. As shown in Fig. 2, the actuation arm 48 of the paddle 11 is provided to engage the engaging end 52 of the spring locking member 53 (Fig. 1) . The spring locking member 53 is provided to extend through the lateral second slot 27 disposed in the lower portion of the housing 12. At the opposite end of the paddle engaging end 52 of the spring locking member 53 is the retaining portion 54 which is shown having a slot 55 provided therein for accommodating a locking pin 56 of a lock plug 23 which is disposed within the lock socket 22. The spring locking member 53 is preferably comprised of a spring steel composition or plastic composition such as for example acetal, or any suitable like flexible member which is also durable enough to withstand the forces of actuation of the latch assembly. In addition, the retaining portion 54 of the locking member 53 is provided with a positioning tab 59 which engages a positioning stop 58 on the housing 12. This facilitates alignment of the locking pin 56 within the slot 55, by maintaining the locking member 53 in a desired position (see Fig. 4) . The positioning stop 58 is shown comprising a detent 58a which extends downward in relation to the positioning tab 59. The positioning tab 59 is preferably provided as a spring member for deflection by the positioning stop 58 as the locking member 53 is slidably moved in parallel relation in the horizontal direction shown by the path of double arrow "d" , from one side to the other of the positioning stop 58. This is accomplished by the selective engagement of the lock plug pin 56 by the user with a key or other operating device. As shown in Fig. 4, the latch 10 is in the unlocked position with the paddle engaging portion 52 of the locking member 53 seen positioned below the actuation arm 48 or the paddle 11 for selective engagement therewith when the paddle 11 is drawn forward. Referring to Fig. 4, in order to lock the assembly, the lock pin 56 is rotated to slide the locking member 53 to the right in the direction of arrow "d" to draw the paddle engaging portion 52 of the locking member 53 out of the reach of the paddle actuation arm 48. In the locked position, while not shown, the positioning tab 59 will be caused to be moved to the right of the positioning stop 58 by the movement of the lock pin 56 and will thus prevent the paddle engaging portion 52 of the locking member 53 from being able to engage the paddle actuation arm 48 when the paddle 11 is lifted. The spring locking member 53 is also provided with a pawl engaging portion 57 which engages the locking arm 37 of the pawl 28. The latch assembly 10 is actuated by lifting the paddle 11 in an upward direction (away from the surface to which the latch assembly 10 is mounted) . The actuation arm 48 of the paddle 11 engages the paddle engaging portion 52 of the locking member 53 (Fig. 2) and the engaging portion 52 is lowered within the lateral second slot 27 of the housing 12. By actuating the locking member 53, it is lowered a distance such that the pawl engaging portion 57 of the locking member 53, which engages the pawl locking arm 37, is moved out of engagement with the pawl locking arm 37 thereby freeing up the pawl 28 for pivoting. The bias provided by the pawl torsional spring 40 releases the pawl 28 from its vertical (Fig. 1 and Fig. 3) position and allows the pawl 28 to rotate to disengage the keeper member 100, thereby opening the compartment or panel to which the latch assembly 10 is attached. The keeper member 100 is shown in Fig. 3 comprising a striker wire, but may comprise any like suitable member such as a bar, claw, or other suitable attachment member. A notched portion 65 is shown in the back of the pawl 36 to provide clearance for the locking member 53, when the pawl 36 is released, as shown in Fig. 2. This facilitates the relief of stress upon the spring locking member 53 when the pawl is in its released (Fig. 2) position. Suitable mounting means are provided to retain the latch assembly 10 on a panel or mounting surface. For example, installation of the latch assembly 10 to a panel may be accomplished with the mounting means shown in Fig. 2 comprising apertures 60,61,62 and guide pins 63,64 for facilitating the fastening of the latch assembly to a panel, such as for example, a glove box of an automobile.
