DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred embodiments will be described wherein
The invention is a load floor latch. Referring to FIG. 1 and FIG. 2, the load floor latch 10 comprises a hoop actuation means 12 and a pawl member 14. The latch 10 is attached to the lid 16 and is engaged with the lid support 18. The lid 16 is supported by a frame 20 and is shown with an attached lid carpet 22.
The hoop actuation means 12 is best illustrated in FIGS. 3 through 7. The hoop actuation means 12 is comprised of a hoop actuation element 24, having a hoop handle 26 with an aperture 28 integrally attached to the proximal end of L-shaped arms 30,32. The L-shaped arms 30,32 have detent features 34,36,38,40 on their outer sides that snap into recesses 34A,36A,38A, and 40A on the hoop legs element 42. The hoop legs element 42 comprises two identical sections 42A,42B connected by a center shaft 44. Each section 42A,42B of the hoop legs element 42 terminates into a pair of snap-in shafts 46,48 positioned parallel with shaft 44 which allows for rotational movement of the hoop actuation means 12 when inserted into lid 16 (described below). The central area of the L-shaped arms comprise stops 30A,32A which limit the rotation of the hoop actuator element 12 to 90 degrees when the latch 10 and lid 16 are detached from the frame 20 (not shown) in the open position. The stops 30A,30B abut the camming surfaces 43A,43B on the hoop legs element 42. Strength ribs 50,52,54,56 located on the topside of each section 42A,42B of the hoop legs element 42 are in contact with the lid 16 during actuation of the latch (described below).
The pawl member 14 is best illustrated in FIG. 8. The pawl member 14 comprises a pawl body portion 58 integral at one end with a living spring 60 terminating with a pawl tail 62, and a slam action ramped element 64 on the opposite end. The living spring 60 flexes during opening and (slam action) closing of the latch 10 based on the displacement of the slam action ramped element 64 (described below). The pawl tail 62 fits into the pawl tail slot 66 (not shown) located between the lid 16 and lid cover 23 to resist movement of the latch 10 when engaged (described below).
The lid 16 and lid cover 23 are best illustrated in FIGS. 9, 10, 11 and 12. The lid 16 is prepared with sidewalls 68,70 having recesses 68A and 70A for insertion of the snap-in shafts 46,48 of the hoop legs element 42. Positioning tab sidewalls 69,71 perpendicular to the recess sidewalls 68,70 have attached v-shaped self positioning tabs 69A 71A to align the snap-in shafts 46,48 for insertion into recesses 68A,70A in the lid 16. The central sidewalls 72,74 are substantially perpendicular to the positioning tab sidewalls 69,71 and form a slot 75 for the pawl member 14.
The lid cover 23 is one piece having a pawl tail aperture 76 and a diagonal camming surface 78 for use as a camming means for the living spring 60 of the pawl member 14 (described below). The diagonal camming surface 78 protrudes upward from the top side 23A of the lid cover 23. The lid cover 23 is attached to the lid 16 by a variety of means such as welding or fixing prior to attachment of the latch 10.
The assembly of the latch and attachment of the latch to the lid is best illustrated in FIGS. 13 through 21. The hoop legs element 42 is attached to the lid 16 by inserting the snap-in shafts 46,48 located on the identical hoop legs element 42A,42B in the recesses 68A,70A on sidewalls 68,70. The snap-in shafts 46,48 flex inward as they slide along sidewalls 68,70 of the lid 16 and are guided into the recesses 68A,70A by the positioning tabs 69A,71A. Once in place, the snap in shafts 46,48 are free to rotate in the recesses 68A,70A.
After the installation of the hoop actuation element, the pawl member 14 is installed by sliding the pawl body 58 along the bottom side 16A of the lid 16 until the slam action ramped element 64 contacts the shaft 44 of the hoop actuator means 12, thereafter inserting the pawl tail 62 into the pawl tail slot 66 formed between the lid 16 and the diagonal camming surface 78. Thus, the pawl member 14 is maintained in place between the shaft 44 and the diagonal camming surface 78 of the lid cover 23. When the latch 10 is installed into the lid 16 and the lid cover 23, the shaft 44 of the actuation assembly 12 is positioned at the base of the slam action ramped element 64 in the closed and engaged position with the lid support 18 (not shown). In the engaged position, the hoop handle 26 is substantially perpendicular to the lid 16. After disengagement, the hoop actuation element 28 can be rotated 90 degrees and become substantially parallel, positioned 180 degrees, to the lid 16. This will ensure that the hoop handle 26 will not be broken or stepped on when in the open position detached from the frame 20 (not shown).
Referring to FIG. 22, the latch 10 is in the closed position and engaged with the lid support 18 by the slam action ramped element 64. In the closed position, the hoop shaft 44 remains at the bottom of the slam action element 64 of the pawl member 14. The snap in shafts 46,48 remain extended in the lid recesses 68A,70A of the lid 16. The living spring 60 of the pawl member 14 is in the relaxed position.
The latch 10 in the activated position is best illustrated in FIG. 23. Activation of the latch 10 is accomplished by pulling the hoop handle 26 upward which forces the hoop shaft 44 to slide upward along the slam action ramped element 64 thereby forcing the pawl member 14 backward, thus forcing the living spring 60 to flex, allowing the slam action ramped element 64 of pawl member 14 to disengage from the lid support 18. As the hoop handle 26 is pulled upward, it rotates slightly backward, thereby causing the hoop legs element to contact the bottom lid surface 16A thereby limiting the rotation of the hoop handle 26.
The raised disengaged latch 10 is best illustrated in FIG. 24. As the latch 10 is raised, the shaft 44 remains at the top of the slam action ramped element 64 of the pawl member 14 thereby causing continued force on the living spring 60 which is maintained in the flexed position. The snap in shafts 46,48 remain in contact with the lid 16 and the pull force is maintained against the lid 100 when lifted.
The latch 10 and attached lid 16 are closed by slam action of the pawl member 14. The latch 10 and lid 16 are aligned and forced downward, contacting the lid support 18 thereby forcing the pawl member 14 backward compressing the living spring 60. The backward movement of the pawl member 14 allows the slam action ramped element 64 to be displaced so as to pass the lid support 18 and then snap back engaging the lid support 18 in the closed position.
Another embodiment of the latch in accordance with the present invention is illustrated in FIGS. 25 through 32. The latch 210 in the present embodiment is similar in both structure and function to many of the features already described in detail with respect to the latch 10, and for this reason, only the differences in the latch 210 from the latch 10 will be described herein for the sake of brevity, Also, for ease of reference, portion in this embodiment similar to the latch 10 will describing using the same number designation except beginning with 210.
FIGS. 25–32 refer to the second embodiment of the present invention. The lid 216 of the second embodiment comprises a pawl holder 280 located between the central sidewalls 272,274 which form a slot 275 for the pawl member 214. The pawl holder 280 is designed to receive the pawl tail 262 of the pawl member 214. The top skin 216B of the lid 216 has a cutout 217 for access to the pawl tail 262. The lid cover 223 is flat with a pawl tail aperture 272.
The pawl member is attached to the lid 216 by sliding the pawl member 214 along the bottom side 216A of the lid 216 until the slam action ramped element 264 contacts the shaft 244 of the hoop actuator means 212, thereafter inserting the pawl tail 262 into the pawl tail holder 280, thus maintaining the pawl member 214 in place between the shaft 244 and the pawl tail holder 280 in the relaxed position. During activation and (slam action) closing of the latch 210, the pawl tail holder 280 is used as a camming means for the flexed movement of the living spring 260 of the pawl member 214.

Assembling the latch is accomplished by simply inserting the handle 714 between the living spring 716 and handle snap-in leg 722.
Referring to FIGS. 80–81, the process of installing a latch 710 in a lid is illustrated. First, the bezel lid hook 724 is inserted into the opening 736 defined within the lid 738, so that the edge 740 closest to the end of the lid 738 is secured within the channel 34. Next, the latch 10 is rotated downward. The bezel lid snap-in leg's ramp 732 strikes the opposite edge 742 of the opening 736, causing the bezel lid snap-in leg 728 to bend so that the hook 730 can pass the edge 742. Once the hook 730 clears the edge 742, the bezel lid snap-in leg 728 returns to its original position, wherein the hook 730 engages the lid 738, securing the latch 710 within the lid 738. To improve the appearance of the lid, a carpet 744 may be secured to the lid 738 and surrounding frame 746, illustrated in FIGS. 82 and 83. The handle 714 is dimensioned and configured so that it will clear both standard carpet 744 and the taller luxury carpet 744.
Alternatively, the bezel 712 and lid 738 may be made from one-piece construction, preferably by injection molding. Because the bezel 712 and lid 738 will be formed from one solid piece, there is obviously no need to install a separate bezel 712 within the lid 738. Once the one-piece bezel 712 and lid 738 was molded, completing the assembly would only require inserting the handle 714 between the living spring 716 and the handle snap-in leg 722.
The operation of the latch 710 is illustrated in FIGS. 83 through 87. The latched position of the latch 710 is shown in FIGS. 82 and 86. In this position, the pawl 718 fits within an opening 748 defined within the frame 746, thereby securing the lid 738 in its closed position. The handle 714 hangs downward against the handle snap-in leg 722, thereby keeping the handle out of the way of any person's feet that may be on top of the lid 738. To open the lid 738, the handle 714 is first raised to the position shown in FIGS. 84 and 87 to facilitate grasping. Continued pulling on handle 714 disengages the pawl from the opening 748, so that further pulling on handle 714 raises the lid 738 to the position shown in FIG. 85. The storage compartment 750 below lid 738 can now be accessed.
To close and secure the lid 738, the lid 738 can simply be slammed shut. As the lid 738 closes, the pawl's ramped surface 720 will strike the frame 746, bending the living spring 716 so that the pawl 718 can pass by the frame 746 and enter the opening 748. Once the pawl 718 enters the opening 748, living spring 716 returns to its original position, so that the pawl 718 engages the frame 746, securing the latch 710 in its latched position.

The button 814 is now installed in the housing 812, and is biased outward by the spring 868. To install the ejector, first the spring 870 is placed over the ejector's spring guide 852. Next, the ejector's shafts 850 are snapped into the housing's apertures 836. The ejector 816 is now biased upward by the spring 870. The latch 810 is now fully assembled.
Referring to FIG. 96, the latch is illustrated installed within a frame 854, securing a lid or load floor 856. The latch 810 is installed in the frame 854 by first inserting the latch 810 into an opening within the frame 854. Referring to FIG. 97, a lid support 858 is then placed on top of the housing's horizontal flange 26. The lid support 858 includes at least two downwardly protruding tabs 860, terminating in barbs 862. The tabs 860 are inserted through the hole 840, bending inward to allow the barbs 862 to pass through the hole 840. An additional hole. 864 is defined within the frame 854, corresponding to the hole 840. Once the barbs 862 clear both the hole 840 and the hole 864, the tabs 860 return to their original position so that the barbs 862 engage the edge of hole 64, thereby securing both the lid support 858 and latch 810 within the frame 854. Lastly, a retainer 866 is inserted into the hole 840, between the tabs 860, thereby preventing the tabs 860 from bending inward, as would be necessary to disengage the lid support 858 from the frame 854.
The operation of the latch 810 is best illustrated in FIGS. 97 through 102. FIGS. 97 and 100 illustrate the lid 856 closed and the button 814 biased outward by the spring 868, so that the lid 856 is secured in its closed position by the pawl 872. The stop tabs 848 engage the edges of the slots 832, thereby preventing further outward movement of button 814. The ejector 816 is forced down by the lid 856, so that the spring 870 is compressed. Pushing inward on the button 814 disengages the pawl 872 from the lid 856, as illustrated in FIGS. 98 and 101. Once the pawl 872 is disengaged from the lid 856, the spring 870 biases the ejector 816 upward, raising the lid 856 a sufficient height so that it may be easily grasped, as illustrated in FIGS. 99 and 102. The ejector 816 stops moving upward when it strikes the ejector stop 838. The button 814 is free to return to its outward position to which it is biased by the spring 868.
The lid 856 is closed by slamming it shut. The lid will strike the button 814, pushing the pawl 872 inward to permit the lid 856 to pass. The lid will depress the ejector 816 as it passes the pawl 872. Once the lid 856 clears the pawl 72, the spring 868 will bias the button 814 outward until the stop tabs 848 engage the edges of the slots 832, so that the pawl secures the lid 856 closed.
A ninth embodiment of the latch 910 is illustrated in FIGS. 103 through 110. The principal difference between the first and second embodiments is the lack of an ejector in the ninth embodiment. Therefore, the housing 912 does not have aperture 836 and a ejector stop 838. This portion of the housing 912 is filled by inner housing wall 912A. The remainder of the latch 910 is identical to the latch of the eight embodiment 810.
