Description: LOAD FLOOR LATCH CROSS-REFERENCE TO RELATED APPLICATIONS This is a continuation-in-part of US application serial no. 09/255,586, filed on February 22, 1999, the complete disclosure of which is herein incorporated by reference. BACKGROUND OF THE INVENTION 1. Field of the nvention 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. 2. Brief Description of the Prior Art Slam-action latches are known in the art and are employed in a number of applications for securing one or more panels together. 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 mounted on it and a second panel member, such as, for example, a cabinet, has a keeper mounted thereon, slamming shut the first panel member against the second panel member can secure the panels with the latch. In many instances, separately provided spring members are utilized to bias the pawl into engagement with a keeper member. Thus, when a panel to which the latch is installed is closed, the pawl engages a keeper. The utilization of a separately provided spring member often increases the cost of the latch and the time for assembly or construction of the latch In some cases, complex mechanisms are required to maintain spring members and align them with a pawl so the pawl can be regulated to operate and engage and disengage a keeper A need exists for a latch which can provide an improvement over the prior art in that it will be less costly to produce and less time-consuming to assemble SUMMARY OF THE INVENTION The present invention provides a novel slam latch having a handle and a housing with a pawl member which is disposed to engage a keeper member to secure a first member, such as a door or floor panel, to a second member, such as a frame or floor. Preferably, the latch can be installed on a closure panel and the keeper member on another panel or frame. The latch handle, upon actuation, retracts the pawl from engagement with a keeper member by contacting the pawl member and forcing the pawl member out from engagement with the keeper to release the latch and permit the closure panel to be opened. The pawl member is a living spring member which permits it to be deflected by engagement with the handle. The pawl member is connected to the housing and extends therefrom. Handle mounting elements pivotally connect the handle to the housing. The pawl member is provided as a flexible member, and preferably is a living spring member, which can be deflected by the handle. A locking mechanism is employed to permit locking of the latch so that the pawl will not be released from the keeper member. An object of the present invention is to provide a novel latch which can secure one or more members together, such as panels or the like, for selective release by actuating a handle of the latch. Another object of the present invention is to accomplish the above objects 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 vehicles to regulate access to and from an area or compartment, such as, for example, a floor panel and a floor storage compartment. Another object of the present invention is to provide a novel latch having a pawl member which is also a living spring member. Another object of the present invention is to provide a locking mechanism which can secure the latch against unauthorized opening. Another object of the present invention is to accomplish the above objects wherein the handle is positioned by positioning elements relative to the housing. Another object of the present invention is to provide resistance when the pawl member is being opened or closed with the handle. Another object of the present invention is to provide one or more elements associated with the handle to increase the latching force of the pawl relative to a keeper.

Preferably, the latch 10 can be installed on a floor panel of a vehicle to regulate access to and from a compartment. Locking means is also provided to lock the latch 10 against unauthorized opening. The locking means is shown comprising a lockplug 15 which has a key slot 16 therein. The locking means further includes retaining means for retaining the lockplug 15 on the housing 1 1. The retaining means is shown in Fig. 2 comprising a retaining member 23 which is disposed on a connecting end 27 of the lockplug 15 located on the lockplug end opposite of the key slot 16 end. Fig. 2 shows the retaining member 23 during assembly, where it is partially installed on the lockplug connecting end 27. The retaining member 23 has an assembly slot 24 having a circular slot portion 25 and a narrow slot portion 26 extending from the circular slot portion 25. The circular slot portion 25 is configured for placement over the connecting end 27 of the lockplug 15. Preferably, the retaining member 23 includes connecting means for connecting it to the connecting end 27 of the lockplug 15 to secure it thereto for corresponding rotational movement with the lockplug 15. 1 e , when the lockplug key (not shown) is rotated in the key slot 16 The retaining member connecting means is shown comprising a pair of tapered walls 30, 31 provided on opposite sides of the narrow slot portion 26 The lock plug 15, preferably, is configured for snap-fit installation of the retaining member 23 onto the connecting end 27 by first positioning the circular slot portion 25 over the lockplug connecting end 27, and then sliding the retaining member 23, from its Fig. 2 position, over the connecting end 27 of the lockplug 15, to its installed position as shown in Figs 6 and 7 The retaining member 23 has a first cam slot 34 with an opening 39 Likewise, the retaining member 23 also has a second cam slot 35 having an enlarged slot portion to facilitate installation of the retaining member 23 on the lockplug connecting end 27 First and second pin members, respectively, 36, 37 are provided on the housing 11 to facilitate holding the retaining member 23 The opening 39 of the first cam slot 34 allows the first cam slot 34 to be moved along the first pin member 36, and the enlarged slot portion of the second cam slot 35 facilitates installation and movement of the second cam slot 35 along the second pin member 37 As shown in Fig 3, the lockplug 15 preferably has an annular groove 28 disposed at the connecting end 27 This permits the retaining member 23 to slide along the groove 28 and snap the narrow slot portion 26 onto the connecting end 27 The tapered walls 30, 31 maintain the retaining member 23 on the connecting end 27 of the lockplug 15 Preferably, the groove 28 has at least two vertical components, such as the vertical wall 29, only one side being shown, there being an identical vertical wall portion on the opposite side. Referring to Figs. 4 and 5, the handle 12 is provided with an aperture 70 to permit the lockplug 15 to be installed therein. A pair of locking legs 71, 72 is disposed on opposite sides of the aperture 70. The locking legs 71, 72 preferably comprise generally L-shaped members. The lockplug 15 is provided with an upper ring portion 75 which is disposed to rotate with a key (not shown). The lockplug 15 has notches 73, 74 disposed in the upper ring portion 75 which are rotated to block the locking legs 71, 72 of the handle 12 and to release the locking legs 71, 72 when the notches 72, 73 are aligned with the locking legs 71, 72. In Fig. 1, the locking legs 71, 72 are shown positioned in a horizontal alignment. In this (Fig. 1) position, the handle 12 is restrained from lifting relative to the housing 11, and the pawl member 13 cannot be moved to unlatch the latch 10 from a keeper. Fig. 3 shows the position of the handle locking legs 71, 72, which are vertically disposed in relation to the notches 72, 73. When the upper ring portion 75 of the lockplug is rotated in either a clockwise or counterclockwise direction, and the notches 72, 73 are aligned with the locking legs 71, 72 of the handle (Fig. 3), the handle 12 can then be lifted for pivoting to engage the pawl member 13. The pawl member 13 is retracted rearwardly into the housing when the handle 12 is fully pivoted (as shown best in its Fig. 10 position). The housing 11 has a cut-out portion 32 disposed in the vicinity of the pawl member 13 to permit the pawl member 13 to be retracted with the handle 12 and/or deflected inwardly, toward the housing 1 1. Preferably, the housing includes flange members 77, 78 disposed on each side of the pawl member 13 and extending parallel to the length of the pawl member 13. The flange members 77, 78 are provided to facilitate clearance of the latch 10 with a keeper member or surface. Referring now to Figs. 6 and 7, the retaining member 23 is installed on the connecting end 27 of the lockplug 15. The housing first pin member 36 and second pin member 37 extend outwardly from the rear surface 38 of the housing 1 1. The first cam slot 34 and second cam slot 35 are positioned for movement along the respective first pin member 36 and second pin member 37 when the lockplug 15 is operated by turning a key (not shown) to rotate the upper ring or locking member 75. The retaining member 23 rotates with the upper ring or locking member 75 of the lockplug 15. The retaining member 23 is shown in Fig. 6, with the lock in the open position, and can be rotated from that position, along the direction of arrow "a," to the latch's locked position (Fig. 7). When the lockplug 15 is in the locked position, the lockplug upper ring or locking member 75 secures the handle 12 against pivotal movement, i.e. lifting, by retaining the locking legs 71, 72 of the handle 12.. During the movement from the open position to the closed or locked position, the retaining member 23 travels along the first and second pin members 36, 37 which facilitate guiding of the retaining member movement. The retaining member 23 secures the lockplug 15 to the housing 1 1 and prevents the lockplug 15 from otherwise being lifted out of the latch 10 with the handle 12. When the lockplug 15 interferes with the locking legs 71, 72 of the handle 12, then the handle 12 is not able to freely move and it cannot pivot to engage the pawl member 13. Reference now being made to Fig. 8, wherein the pawl member 13 is shown having a leg portion 40 which is connected to the housing 11 and extends downwardly from the housing flange 14. Preferably, the pawl member 13 comprises a living spring member, which, as shown in Fig. 10, permits the pawl member 13 to be moved along a generally radial path through the movement of the leg portion 40 when the handle 12 is actuated.
