Description: LOAD FLOOR SLAM-ACTION PAWL LATCH CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. Application No. 09/163,254 filed September 30, 1998 and claims priority from U.S. Application No. 60/110,384 filed December 1, 1998. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of latches and more particularly to slam action latches in which a handle is lifted to release the latch from engagement. 2. Brief Description of the Prior Art Slam-action latches are known in the art and are employed in a number of applications. Generally, latches coming within this category operate by forcing a pawl into engagement with a keeper. For example, where a first panel member has a pawl and a second panel member, such as, for example, a cabinet, has a keeper thereon, slamming shut the first panel member against the second panel member secures the panels. In many cases, floor compartments of vehicles need to be secured so that when the vehicle is operating, the floor panel will not become detached. A loose or detached panel can cause the compartment contents to escape and further can damage the panel and floor if repeated slamming of the door panel and frame occurs. A floor panel generally covers areas or compartments which must be readily accessed for maintenance and storage purposes. A latch is needed which will secure a floor panel upon closing the panel and which can be readily actuated to release the floor panel to thereby provide access to the area below the panel. SUMMARY OF THE INVENTION The present invention provides a latch having a housing which holds a handle, a pawl member and a spring which biases a pawl into engagement with a keeper member. The latch handle retracts the pawl from engagement with a keeper member by engaging the pawl. As the handle is lifted it pivots relative to the housing to engage the pawl and draw the pawl away from the keeper member. The pawl is retracted against the bias of the spring member. When the handle is released, the spring member then returns the pawl to its engaging position. The latch can be closed by slamming the panel to which it is mounted shut. Alternately, the handle can be lifted to move the pawl out of the way of the keeper while the panel is closed, and then the handle can be released to allow the pawl to extend so as to be engaged by the keeper member. The housing preferably provides a gripping area or recess for facilitating grasping of the handle by a user. The housing can further provide a barrier to the compartment covered by the floor panel so that no objects inadvertently fall into the compartment through the latch. It is a primary object of the present invention to provide a latch which is useful for securing a first panel or member to a second panel or member. It is another object of the present invention to provide a latch which can be used in an installation where the latch is mounted on a closure panel to regulate entry into an enclosure covered by the closure panel and provide a barrier to prevent a user's hand or fingers, or objects, from inadvertently entering the compartment. Another object of the present invention is to provide a novel latch which can secure one or more panels or members together, for release upon actuating a handle of the latch. Another object of the present invention is to accomplish the above oϋjects by providing a spring-biased latch which can be closed by slam-action. Another object of the present invention is to provide a latch which can be used in connection with panels of automobiles, such as, for example, a floor panel, to regulate access to and from an area or compartment. Another object of the present invention is to provide a novel latch which can be constructed from few components. Another object of the present invention is to provide a latch winch can be mounted to a closure panel by snap-fitting a housing into a panel cut-out. Another object of the present invention is to provide a detent mechanism for holding the handle in a preferred position relative to the housing. Another object of the present invention is to provide a drag mechanism for imparting a resistance to the handle when it is pivoted. Another object of the present invention is to accomplish the above objects where a single spring element is used to bias the pawl into a latching engagement with a keeper and to bias the handle into a closed position.

Grip facilitating means can also be provided on the handle 12, shown best in Fig. 13, comprising an extended or thicker portion 70. The latch 10 preferably comprises barrier means for guarding against inadvertent access to the compartment being covered by the closure panel (not shown) to which the latch 10 is mounted. The barrier means preferably comprises a lower surrounding flange portion 75 which is provided as a portion of the housing 11 in the area below the handle 12. The surrounding flange 75 is spaced from the handle gripping portion 17 to provide adequate access for gripping the handle 12, while providing a barrier to items, debris, and the like from passing through the latch assembly 10 to the closure compartment (not shown). The surrounding flange 75 further prevents inadvertent entry of a user's fingers or hand into the closure compartment when the latch 10 is actuated. While not shown, it is also conceivable that a lock can be utilized with the present latch. For example, a lock cylinder may be integrated with the housing 11 to prevent the handle or pawl movement to take place when locked. This could be achieved, for example, with a lockplug. For example, the lockplug can be installed in the handle 12 or housing 11 to selectively secure the handle 12 to the housing 11 to prevent relative movement thereof and thereby prevent the latch 10 from being opened. In Figs. 18-38 are illustrated the components of another embodiment of a load door latch in accordance with the present invention. For the sake of brevity, only portions of the present embodiment which differ from the load floor latch 10 will be described herein. In Figs. 25-31 is illustrated a handle 212. As illustrated in the bottom plan of Fig. 30, the handle 212 includes coring within its bottom surface 240, which operates to reduce the amount of material required for manufacture of this component. As should be understood, while a specific geometry of coring is illustrated in Fig. 30, any desired geometry can be provided for the same purpose. In addition, as illustrated in Fig. 30, the handle 212 as compared with the handle 12 does not incorporate the features of the members 55 and 56 and supporting elements 62 and 63 which have been eliminated. In Figs. 18-24 is illustrated a housing 211 of the present embodiment. As illustrated in the bottom plan view of Fig. 23 and the perspective view of Fig. 24, the housing 211 includes a plurality of coring depressions 250 within its upper and lower surfaces, which operate to reduce the amount of material for this component and accordingly also the weight. As should be understood, the number and configuration of the depressions 250 can be adjusted where desired.
