[0102] Although the invention is shown and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made to the details within the range and range of equivalents of the claims without departing from the invention.

[0103] First embodiment

[0104] exist Figures 1A to 14B 1 shows a first embodiment of a door assembly 100 incorporating aspects of the present invention. The door assembly 100 generally includes a door 102 (only the front panel of which is shown). The door 102 may be, for example, a glove box door for a vehicle. Although not shown, the door is mounted on an opening, such as an opening formed in a dashboard of a vehicle. As is known in the art, the door 12 is hinged to the opening and can be moved between a closed position and an open position.

[0105] In the closed position of the door 102, the front surface 107 of the door is flush with the surface of the instrument panel. In the open position of the door 102, the door 102 protrudes from the surface of the instrument panel. A striker (not shown) is provided at the periphery of the opening of the instrument panel.

[0106] The door 102 may be a unitary component or comprised of multiple components mounted together. The door 102 comprises a generally rectangular shape having a generally rectangular recessed area 106 on its front surface 107. Two protrusions 115 and 119 protrude outwardly from the rear surface of the door 102 in a rearward direction.

[0107] The projection 115 includes an aperture extending therethrough. A hollow square clip 121 is mounted into the aperture in the projection 115, with each inwardly facing side of the clip 121 including a resilient tab 129 that accommodates lateral movement of a pawl located therein.

[0108] The projection 119 has a free end 131 which is narrower than the rest of the projection 119. Fig.13D As best shown. An elongated recess 133 or channel is formed on the rearwardly facing surface of the free end 131. Figures 13A-13DThe functions of the protrusions 115 and 119 are described in more detail.

[0109] The latch assembly 104 is mounted to the door 102 to releasably hold the door 102 in a closed position. The latch assembly 104 is at least partially positioned within the recessed area 106 of the door 102 so that the front surface of the paddle 400 of the latch assembly is flush with or slightly recessed relative to the front surface 107 of the door 102. Alternatively, the paddle 400 may protrude slightly or significantly, depending on design decisions. The latch assembly 104 is mounted to the recessed area 106 of the door 102 by a threaded fastener 109 and a clip 307 on the housing 300 of the latch assembly 104. As will be described later with reference to the method of assembling the door assembly 100.

[0110] The fastener 109 together with the clip 307 constitutes a means for mounting the latch assembly 104 to the door 102. It should be understood that the means for mounting can vary. For example, the means for mounting can include a plurality of clips, a plurality of fasteners, snaps, clamps, welds, adhesives, barbs, grooves, prongs or surfaces, for example, or any other means that can be used to mount the latch assembly 104 to the door 102.

[0111] Now refer to Figure 1B , Fig.14A and Fig. 14B , at least a portion of the latch assembly 104 (including the rotor 500 and the two pawls 112, 114) protrudes from the rear surface 110 of the door 102 and passes through an opening 113 formed in the recessed area 106. The pawls 112 and 114 are configured to releasably engage a striker on the vehicle opening. When the pawls 112 and 114 are engaged with the striker, the door 102 is held in the closed position. The engagement between the free ends 112a and 114a of the pawls 112 and 114, respectively, and the corresponding striker prevents the door 102 from moving from the closed position to the open position. When the pawls 112 and 114 are disengaged from the striker, the door 102 is either held in the open position or can be easily moved to the open position.

[0112] Opposite the free end 112a and 114a of each pawl 112 and 114 are posts 120 and 127, respectively, connected to the rotor 500 of the latch assembly 104. Fig.14A As shown, the post 120 of the pawl 112 includes a shaft 128a extending from the end of the pawl 112, a bulbous portion 128b at the free end of the shaft 128a, and an annular channel 128c defined between the shaft 128a and the bulbous portion 128b. Although not explicitly shown, it should be understood that the post 127 of the pawl 114 is substantially the same as the post 120. It should be understood that the connection between the pawls 112 and 114 and the rotor 500 can be any type of connection (fixed or releasable) and is not limited to the connection shown.

[0113] Now refer to Figure 1B and 13A - Fig.13D , the pawl 114 is positioned to pass through the clip 121 on the door 102 and is mounted above the protrusion 119 on the door 102. The pawl 114 includes a guide section 123 that interacts with the protrusion 119. The guide section 123 includes an opening 124 formed at a widened area of ​​the pawl 114. Two prongs 125 extend into the opening 124 and extend toward each other from opposite sides of the opening 124. The prongs 125 are close to but do not cross the central axis "E" ( Fig.13A ). Each fork tine 125 is v-shaped and the tip of the v-shaped tip faces the central axis E.

[0114] Fork teeth 126 are formed on the sides of the opening 124 adjacent to the two sides where the fork teeth 125 are installed. The fork teeth 126 extend along the axis E. In addition, as shown in FIG. Fig.13A As shown, tine 126 extends along central axis E to a length such that it passes over tine 125. Tine 126 is positioned at a height above tine 125 such that tines 125 and 126 do not contact each other. Fig. 13C As shown. The prongs 125 and 126 can be formed integrally with the pawl 114 or provided on a separate component mounted in the opening 124. The prongs 125 and 126 are flexible. The prong 125 interacts with the side of the free end 131 of the protrusion 119, as shown. Fig.13D As shown, the fork tine 126 interacts with the recess 133 formed in the free end 131. Figures 13A-13D The interaction between the pawl 114 and the protrusion 119 is described in more detail.

[0115] Figure 2 An exploded view of the latch assembly 104 is shown. The major components of the latch assembly 104 are a base housing 300, a user-operated paddle 400, a rotor 500, a lock barrel 600, torsion springs 700 and 800, and optionally, two pawls 112 and 114. The base housing 300 can be mounted to the front side of the door and remains fixed in place (i.e., stationary) during operation of the latch assembly 104. The paddle 400 pivots relative to the front surface 302 of the housing 300 about a pivot axis A (see FIG. 1 ). Fig. 12C ) is pivotally mounted. The rotor 500 is pivotally mounted about a concentric axis B (see Fig. 9C , Fig. 10C and Fig. 11C) is rotatably mounted to the rear surface 304 of the housing 300. The pawls 112 and 114 (which may or may not be considered to form part of the latch assembly 104) are mounted to the rotor 500. The lock cylinder 600 is mounted to the housing 300 and is aligned with the opening 402 in the paddle 400. The lock cylinder 600 is configured to lock or unlock the latch assembly 104. The lock cylinder 600 is an optional component and may be omitted. The torsion spring 700 is connected to the paddle 400 to hold the paddle 400 in place. Figure 1A The second torsion spring 800 is connected to the rotor 500 to bias the rotor 500 to a rotational position corresponding to the closed state of the latch assembly 104 (ie, wherein the pawls 112 and 114 are engaged with the striker).

[0116] The various components of the latch assembly 104 will now be described in greater detail.

[0117] Figure 3A-3G The base housing 300 of the latch assembly 104 is depicted, having a generally rectangular body to which the other components of the latch assembly 104 are mounted. A recess 301 extends through the housing 300 (unless the latch assembly 104 does not include a lock cylinder 600). The outer barrel of the lock cylinder 600 is secured within the recess 301.

[0118] The base housing 300 includes a clip 307 for mounting the door 102. The clip 307 is formed on one side of the housing 300. The clip 307 is a flexible tab or prong that extends outward from the side of the housing 300. The clip 307 may also be referred to herein as a retaining feature, and the retaining feature may be, for example, a post, a surface, a clamp, a slot, or a protrusion.

[0119] Two arcuate ribs 310 protrude from the side wall 311 of the housing 300. The ribs 310 are configured to be positioned within corresponding arcuate slots 404 provided on the side wall 311 of the paddle 400. The slots 404 are longer (measured in length or arc length) than the ribs 310 to enable the paddle 400 to pivot relative to the housing 300 (compare Fig. 12A and Fig. 12B Due to the engagement between the groove 404 and the rib 310 , the paddle 400 can pivot about the axis A relative to the housing 300 .

[0120] More generally, rib 310 may be referred to as a paddle mounting portion of housing 300. It should be appreciated that the connection between housing 300 and paddle 400 may be different than that shown and described. For example, paddle 400 may be connected to housing 300 by, for example, a post, clip, shaft, fastener, pin, or hinge.

[0121] A hollow barrel 312 protrudes rearwardly from a rear surface 304 of the housing 300. The barrel 312 is colinear with the recess 301, and the interior of the barrel 312 defines at least a portion of the recess 301. The barrel 312 is interrupted by two flexible tines 314 located on opposite sides of the barrel 312. Each tine 314 includes a barb 316 at its end, and each tine 314 is configured to flex relative to the barrel 312. The barbs 316 are configured to connect to the grooves 506 formed in the rotor 500. The engagement between the barbs 316 and their respective grooves 506 retains the rotor 500 to the housing 300. The grooves 506 are longer (measured in length or arc length) than the barbs 316, so that the rotor 500 can rotate relative to the housing 300 without disengaging from the housing 300 (compare Fig. 9C , Fig. 10C and Fig. 11C ).

[0122] The engagement between the housing 300 and the rotor 500 can be varied. For example, the tines 314 can be fixed (rather than flexible) and keyed with slots formed in the rotor 500. In addition, the interface between the barrel 312 and the hollow space 530 formed by the cylindrical inner wall 501 can be switched so that the inner diameter of the barrel 312 (rather than the outer diameter of the barrel 312) is the interface with the rotor 500, as shown.

[0123] More generally, the barrel 312 and the tines 314 may be referred to as the rotor mounting portion of the housing 300. It should be appreciated that the connection between the housing 300 and the rotor 500 may be different than that shown and described. For example, the rotor 500 may be connected to the housing 300 by, for example, a post, clamp, barb, surface, fastener, clip, or shaft.

[0124] The rotor mounting portion of the housing 300, the rotor 500 and the lock cylinder 600 at least partially overlap each other along the axis "B" and are concentrically aligned along the same axis "B". This arrangement results in a reduced depth "D" of the latch assembly 104 (see Fig. 9B ), which results in a reduction in the depth of the recess 106 required to accommodate the latch assembly 104 in the glove box door 102, thereby increasing the available storage space in the glove box. Conversely, if the rotor mounting portion, the rotor, and the lock cylinder are offset from each other and do not overlap, such an arrangement results in an increase in the depth of the latch assembly, increasing the depth of the recess 106 required to accommodate the enlarged latch assembly in the glove box door 102, thereby reducing the available storage space in the glove box.

[0125] Two alignment pins 318 ( Figure 3A ) protrudes from the rear surface 304 of the housing 300. Each pin 318 is configured to be inserted into a hole 130 ( Figure 1B ) for alignment purposes.

[0126] Two tracks 320 are formed on opposing side walls 311 of the housing 300. When the paddle 400 is pivoted, a post 407 on the paddle 400 travels in a corresponding track 320. The post 407 interacts with the track 320 to limit the pivoting action of the paddle 400 beyond a predetermined point and assists in preventing the paddle 400 from detaching from the housing 300. Each track 320 is an indentation formed in the side wall 311. The track 320 protrudes into and is at least partially formed on a shoulder 317 formed on the underside of the rear surface 304 of the housing 300.

[0127] Figure 4A-4G The paddle 400 of the latch assembly 104 is depicted. The paddle 400 includes a generally rectangular front surface 410 in the form of a wall. An opening 402 for accommodating the lock cylinder 600 is defined in the surface 410. If the lock cylinder 600 is omitted, the opening 402 can be omitted. An end 412 of the front surface 410 farthest from the slot 404 is configured to be grasped by a user of the latch assembly 104. Opposing side walls 414 and 416 protrude downwardly from the front surface 410. The side wall 414 includes one of the two slots 404, and a circular leg 420 extending downwardly from the wall 414 at a position adjacent to the slot 404. The circular leg 420 is configured for rotating the rotor 500, as will be described later. One of the two posts 407 extends inwardly from the bottom edge of the side wall 414 toward the side wall 416. The side wall 416 includes the other of the two slots 404. The other of the two posts 407 extends inwardly from the bottom edge of the side wall 416 toward the side wall portion 414. As described above, in the assembled form of the latch assembly 104, each post 407 is positioned within one of the tracks 320 of the housing 300.

[0128] Figure 5A-5E The rotor 500 of the latch assembly 104 is depicted. The rotor 500 is a generally circular body that is capable of rotating relative to the housing 300 against the bias of the spring 800. Two crescent-shaped recesses 510a and 510b (individually or collectively referred to as recesses 510) are defined on the periphery of the rotor 500. Each recess 510 is configured to releasably couple with one of the posts 120 and 127 of the pawls 112 and 114, respectively. The posts 120 and 127 are capable of pivoting within the recesses 510 without being separated from the recesses 510 during operation.

[0129] Each recess 510 is defined by a C-shaped clamp having a non-continuous perimeter. The non-continuous perimeter defines an opening 511 through which a post 120 or 127 can be inserted into the C-shaped clamp (depending on a method of mating the post with the rotor). Figure 5BAs shown, an annular rib 513 projects around the periphery of each recess 510. The rib 513 is positioned between the front and rear surfaces of the rotor 500. In assembled form, the rib 513 is positioned within a corresponding recess 128c in the pawls 112 and 114.

[0130] Various prior art latch designs include a post on the rotor that couples to a recess on the pawl (i.e., the opposite of the post and recess arrangement in latch assembly 100). Positioning posts 120 and 127 on pawls 112 and 114 and recess 510 on rotor 500 to receive posts 120 and 127 provides the ability to bias pawls 120 and 127 into engagement with rotor 500 in the event of rapid deceleration or a crash. This arrangement also provides additional rigidity, allowing pawl 112 to rotate without pivoting pawl 112.

[0131] The rotor 500 includes a bottom wall 512 having a stepped surface. In the assembled form of the latch assembly 104, the bottom wall 512 is oriented generally parallel to the rearwardly facing surface 304 of the housing 300. A generally cylindrical inner wall 501 and a generally cylindrical outer wall 503 protrude orthogonally from the bottom wall 512.

[0132] An annular recess or channel 502 is defined on the forward side of the rotor 500 and is formed between walls 501 and 503. Recess 502 is sized to receive the helical body of spring 800. Recess 504 intersects and is tangential to annular recess 502. Recess 504 is defined on the periphery of the rotor 500 and forms a shoulder 505 where recess 504 intersects a peripheral surface 507 of the rotor 500. One of the free legs of spring 800 is positioned in recess 504 and the leg is placed on shoulder 505.

[0133] Two grooves 506 are formed at the base of the inner wall 501 of the rotor 500. The grooves 506 are circumferentially positioned relative to each other along the circumference of the inner wall 501. As described above, the barbs 316 of the housing 300 are configured to be connected to the grooves 506 so that the rotor 500 is rotatably mounted to the housing 300. The grooves 506 extend into the bottom wall 512. In operation, the rotor 500 can be rotated until the ends of the grooves 506 contact the fixed barbs 316 of the housing 300. As described above, the housing 300 (and its barbs 316) are stationary, and the rotor 500 rotates relative to the fixed housing 300.

[0134] The inner wall 501 forms a hollow space 530 for receiving the end of the lock cylinder 600. The post 514 protrudes upward from the center of the bottom wall 512 in the same direction as the inner wall 501. A crescent-shaped opening 515 extends through the bottom wall 512. The post 604 of the lock cylinder 600 is movably positioned in the crescent-shaped opening 515. The crescent-shaped opening 515 includes a crescent-shaped groove defined by two opposite ends 515a and 515b. The central axis of the crescent-shaped opening 515 is roughly aligned with the rotation axis "B" of the rotor 500. The post 514 is configured to increase the rigidity of the rotor 500 at the interface between the post 604 and the opening 515.

[0135] A bearing surface 520 is defined on the peripheral surface 507 of the rotor 500. In operation, the leg 420 of the paddle 400 bears on the bearing surface 520 to cause the rotor 500 to rotate against the bias of the spring 800, as will be described later.

[0136] One or more of the housing 300, the paddle 400, and the rotor 500 may be constructed of plastic and made by an injection molding process, or constructed of metal (such as aluminum) and made by, for example, a casting process. Other acceptable materials and material forming processes are known to those skilled in the art.

[0137] Fig. 6A and Figure 6B The lock cylinder 600 of the latch assembly 104 is depicted. The lock cylinder 600 is rotatably mounted to the housing 300 and radially aligned with the opening 402 in the paddle 400. A shoulder 602 formed on the top end of the lock cylinder 600 is disposed on the forward facing side 302 of the housing 300. The outer body of the lock cylinder 600 is rotationally fixed relative to the housing 300. The lock cylinder 600 includes an internal cylinder 603 that is rotatable relative to the housing 300 and the outer body of the lock cylinder 600. A post 604 extends from the internal cylinder 603 and is rotatable with the internal cylinder 603. The lock cylinder 600 is a solid body except for a series of internal wafers 607 that are configured to extend and retract in a lateral direction relative to the internal cylinder 603.

[0138] The post 604 extends from the rear surface of the lock cylinder 600. As is known in the art, the post 604 can rotate about the central axis B of the lock cylinder 600 when a suitable key (not shown) is inserted into the keyhole of the inner cylinder 603 of the lock cylinder 600 and rotated in the inner cylinder 603. A crescent-shaped recess 606 is formed on the rear end of the lock cylinder 600 at a position adjacent to the post 604. In the assembled form, the post 514 of the rotor 500 is movably seated in the recess 606.

[0139] As is known in the art, the inner cylinder 603 is configured to be moved between an unlocked state and a locked state using a key. In the locked state of the lock cylinder 600, the paddle 400 is prevented from moving. Figure 1A The initial state shown is rotated about axis A. The key is installed so that the contact piece 607 is retracted and disengaged from the housing 300, which allows the lock cylinder 600 to rotate with the key. In the unlocked state, the user can rotate the paddle 400 to Figure 1A The original state shown and rotated away from the original state. It should be understood that Figure 1A In the initial state of the paddle 400 shown, the pawls 112 and 114 are engaged with their respective strikers. In the initial state of the paddle 400, the lock cylinder 600 can be locked or unlocked.

[0140] The lock cylinder 600 may be different than shown and described. As a non-limiting example, the lock cylinder 600 may be electronically operated. As another alternative, the lock cylinder may be omitted from the latch assembly 104 as a whole. If the lock cylinder 600 is omitted, the paddle 400 will not require the hole 402. The geometry, location and structure of the post 604 may vary. The lock cylinder 600 may be mounted to the paddle 400 (or other components) in a variety of ways.

[0141] Figure 7 The torsion spring 700 of the latch assembly 104 is shown. The torsion spring 700 is connected to the paddle 400 for holding the paddle 400 in place. Figure 1A In the original position of the paddle 400, the rearward surface 405 ( Figure 4B ) faces (and is parallel to) the front surface 302 of the housing 300 ( Figure 3B ).

[0142] The torsion spring 700 includes a spiral body 702 having two free ends 704 and 706. The free ends 704 and 706 extend in opposite directions along independent axes that are both oriented parallel to the central axis of the spiral body 702.

[0143] In the assembled form of the latch assembly 104, the spiral body 702 is positioned in a recess 303 ( Figure 3B ). The end 704 of the spring 700 is either positioned in an aperture or against a surface of the recess 303 of the housing 300, while the other end 706 of the spring 700 is positioned against the rearward surface 405 of the paddle 400.

[0144] Figure 8Shown is a torsion spring 800 of the latch assembly 104. The torsion spring 800 is connected to the rotor 500 for biasing the rotor 500 to a rotational position corresponding to the closed state of the latch assembly 104 (ie, wherein the pawls 112 and 114 are engaged with the striker).

[0145] The torsion spring 800 includes a spiral body 802 having two free ends 804 and 806. The free ends 804 and 806 extend in opposite directions along independent axes that are both oriented parallel to the central axis B of the spiral body 802. In the assembled form of the latch assembly 104, the spiral body 802 of the spring 800 is mounted within the annular recess 502 formed on the front side of the rotor 500, as described above.

[0146] Although not shown, a shock absorber formed of a soft material may be disposed between the rear surface of the paddle 400 and the top surface of the housing 300 in order to limit the generation of sound when the paddle moves to the original position.

[0147] Now describing the assembly process of the latch assembly 104, the lock cylinder 600 is installed in the recess 301 of the housing 300 so that the outer core 300 is fixed to the housing 300 and the inner cylinder 603 (and the post 604) can rotate relative to the housing 300.

[0148] The spiral body 802 of the spring 800 is mounted on the cylinder 312 of the housing 300. The free end 806 of the spring 800 is then positioned in the groove 306 of the housing 300. The rotor 500 is then moved on the cylinder 312 of the housing 300. The free end 804 of the spring 800 is positioned in the recess 504 of the rotor 500. The rotor 500 is then rotated to wind the spring 800. The rotor 500 is continued to move on the cylinder 312 and rotated to a suitable position so that the barb 316 of the housing 300 is finally retained in the groove 506 of the rotor 500.

[0149] The spiral body 702 of the spring 700 is positioned in the recess 303 ( Figure 3B ). The end 704 of the spring 700 is positioned in the aperture or against the surface of the recess 303 of the housing 300. The paddle 400 is then mounted to the housing 300 by positioning the ribs 310 in the corresponding grooves 404 of the paddle 400. The other end 706 of the spring 700 is positioned against the rearward surface 404 of the paddle 400. The point at which the end 706 of the spring 700 contacts the paddle 400 is located behind the axis A so as to bias the paddle 400 to the home position.

[0150] It should be noted that before assembling the paddle, a separate resilient element can be installed to act as a shock absorber between the housing and the underside of the paddle. This will serve to reduce the noise when releasing the paddle.

[0151] It should also be noted that the lock cylinder 600 may be installed last and after the entire assembly is installed and mounted in the door system. There may be applications where the lock cylinder is installed near the end of a vehicle production line. This does not exclude the lock being installed earlier and supplied as a complete unit, but even in this case, the lock is installed after the paddle is installed.

[0152] It should also be noted that a passage that allows access to the retention contact piece on the lock cylinder is formed in the housing (close to 309). By this method, when the pick is opened to full rotation, a tool can be accessed to the lock cylinder retention contact piece and allow the removal and maintenance of the lock cylinder.

[0153] The latch assembly 104 is now assembled and ready to be assembled to the door 102 to form the door assembly 100 .

[0154] To assemble the door assembly 100, the latch assembly 104 (now assembled) is moved toward the opening 113 in the door 102 until the clip 307 of the housing 300 is aligned with the slot 122 ( Figure 1B ) to form a snap, clamp or other engagement. Thereafter, the rear surface 304 of the housing 300 is placed against the front surface of the door 102, and the pins 318 on the housing 300 are aligned with the holes 130 ( Figure 1B ) is positioned. The fastener 109 is then moved from the rear side of the door 102 through the hole 117 of the door and into the hole 309 at the rear surface 304 of the housing 300. The fastener 109 is threadedly fastened to the hole 309 in the housing 300, thereby captivating the latch assembly 104 to the door 102.

[0155] Assembly of the latch assembly 104 to the door 102 is accomplished by the snap-fit ​​engagement described above (by means of items 307 and 122) and only a single fastener 109 engaging from the rear surface of the door 102. This mounting scheme allows for ease of assembly and precision of assembly.

[0156] The post 120 of the pawl 112 is installed in the recess 510a of the rotor 500. The end 114a of the pawl 114 is then positioned to pass through the clip 121 ( Figure 1B ) in the opening. The post 127 of the pawl 114 is then installed in the recess 510b of the rotor 500.

[0157] like Fig.14A and Fig. 14BAs best shown in FIG. 5 , posts 120 and 127 may be inserted into their respective recesses 510 from two different directions orthogonal to each other. More specifically, as shown in FIG. Fig.14A As shown, posts 120 and 127 can be inserted into their respective recesses 510 in the front-to-back direction. Fig. 14B As shown, posts 120 and 127 may be inserted into their respective recesses 510 in the left-right direction via opening 511. The mating orientation of posts 120 and 127 in their respective recesses 510 prevents posts 120 and 127 from accidentally being removed from their recesses 510.

[0158] The guide section 123 of the pawl 114 comes to rest on the free end of the projection 119 on the door 102 .

[0159] The door assembly 100 is now assembled and ready for operation. It should be understood that the above description of assembling the latch assembly 104 and the door assembly 100 is not limited to any steps or order of steps and may vary from what is described without departing from the scope and spirit of the present invention.

[0160] The method of operation of the door assembly 100 is now described. Fig.9A , Fig. 9B , Fig. 9C and Fig. 12A The latch assembly 104 is shown in the closed and locked position, because the lock cylinder 600 is maintained in the locked state, thereby preventing the paddle 400 from pivoting outwardly from its original position shown in these figures. More specifically, as shown in FIG. Fig. 9C As clearly shown, because the post 604 of the lock cylinder 600 is positioned against the end 515a of the crescent-shaped opening 515 of the rotor 500, the paddle 400 is prevented from pivoting outwardly. If a user attempts to pivot the paddle 400 while the latch assembly 104 is held in the locked position, the rounded leg 420 of the paddle 400 will bear against the bearing surface 520 of the rotor 500, thereby causing the rotor 500 to rotate in a counterclockwise direction, such as from Fig. 9C However, the rotor 500 will be prevented from rotating in the counterclockwise direction due to the engagement between the locking post 604 and the end 515a of the crescent-shaped opening 515. Before the paddle 400 can be pivoted to the open position, the lock cylinder 600 must be unlocked (thus moving the post 604).

[0161] Now turn to Fig. 10A , Fig. 10B , Fig. 10C and Fig. 12A The user inserts the key into the key hole 605 of the lock cylinder 600 and rotates the inner cylinder 603 (see Fig. 10C ), thereby converting the lock cylinder 600 from a locked state to an unlocked state, as is known in the art. Fig.9Aand Fig. 10A The orientation of the key hole 605 in FIG. Fig. 10C , the unlocking inner cylinder 603 causes the post 604 of the lock cylinder 600 to move away from the end 515a of the opening 515 of the rotor 500 and become centered (or substantially centered) within the opening 515. At this stage, the latch assembly 104 is still in the closed position, however, because the post 604 no longer abuts the end 515a of the opening 515 of the rotor 500, the rotor 500 is now able to rotate in a counterclockwise direction. In the closed position of the latch assembly 104, the door assembly 100 cannot be moved relative to the opening of the motor vehicle in which the door assembly 100 is installed without rotating the paddle 400, as will be described below.

[0162] Now go to Fig.11A Figure 11B Fig. 11C and Fig. 12B To move the latch assembly 104 to the open position, the user then overcomes the bias of the spring 700 and moves the paddle 400 in an outward direction about the axis A (see Fig. 12B As the paddle 400 rotates outward, the groove 404 slides on its corresponding rib 310 of the housing 300. Fig. 11B As shown, the paddle 400 rotates relative to the lock cylinder 600. At the same time, the round leg 420 of the paddle 400 is supported on the support surface 520 of the rotor 500, thereby causing the rotor 500 to rotate in the counterclockwise direction, such as from Fig. 11C Since the post 604 is spaced apart from the end 515a of the opening 515 of the rotor 500, the rotor 500 is free to rotate in the counterclockwise direction against the bias of the spring 800.

[0163] As the rotor 500 rotates, the slots 506 of the rotor 500 travel over the tines 314 of the housing 300. Additionally, as the rotor 500 rotates, the pawls 112 and 114 move inwardly toward the housing 300 (compare Fig. 10B and Fig. 11B As the pawl 114 moves inward, the fork teeth 125 ( Fig.13D ) slides along the side of the protrusion 119. The posts 120 and 127 can rotate relative to their respective recesses 510 (of the rotor 500).

[0164] Rotation of the paddle 400 and rotor 500 toward the open position stops once (i) the tines 314 bear against the ends of their respective slots 506, (ii) the ribs 310 bear against the ends of their respective slots 404, and / or (iii) the posts 407 on the paddle 400 contact the shoulders 317 on the housing 300. At this point, the legs 420 of the paddle 400 remain in contact with the bearing surfaces 520 of the rotor 500 to avoid disengagement from the rotor 500. In the open position of the latch assembly 104, the door assembly 100 can be moved relative to the opening of the motor vehicle in which the door assembly 100 is installed.

[0165] When the user releases the paddle 400, the spring 700 returns the paddle 400 to the Fig. 12A At the same time, the spring 800 causes the rotor 500 to rotate clockwise back to the original position. Fig. 10C The spring 800 also returns the paddle to its original position due to the engagement between the leg 420 and the bearing surface 520. As the rotor 500 rotates in the clockwise direction, the pawls 112 and 114 move outwardly and away from the housing 300 so that the ends 112a and 114a of the pawls 112 and 114, respectively, can engage a striker (not shown) on the opening of the motor vehicle in which the door assembly 100 is installed.

[0166] The user then closes the door assembly 100, thereby concealing the opening in the motor vehicle and causing the ends 112a and 114a of the pawls 112 and 114, respectively, to engage a striker (not shown) on the opening of the motor vehicle.

[0167] At this stage, the lock cylinder 600 is still in the unlocked state. As is known in the art, the user can insert the key into the keyhole 605 of the lock cylinder 600 (if not already inserted) and rotate the inner cylinder 603, thereby converting the lock cylinder 600 from the unlocked state to the locked state. Locking the inner cylinder 603 causes the column 604 of the lock cylinder 600 to move toward and bear on the end 515a of the opening 515 of the rotor 500, thereby preventing the rotor 500 from rotating in the counterclockwise direction and preventing the latch assembly 104 from being opened. In the locked state of the latch assembly 104, the pawl, paddle and rotor are all locked in place and prevented from rotating. This feature provides improved safety and performance in impact situations and can reduce BSR (shock, squeak and rattle).

[0168] Now refer to Figures 13A-13D In the event that the door assembly 100 moves, for example due to normal use or accident, the guide section 123 of the pawl 114 limits the unintended deflection travel of the pawl 114 relative to the door 102. More specifically, the prongs 125 of the guide section 123 press against the side of the free end 131 of the protrusion 119, such as Fig.13DAs shown, the pawl 114 is limited or prevented from deflecting along the axis F (see Fig.13D The tines 126 of the guide section 123 are hard stops that interact with the recess 133 formed at the free end 131 of the projection 119 to limit or prevent the pawl 114 from deflecting downwardly along the axis G (see Fig. 13C ). The prongs 125 and 126 are bendable to accommodate a limited amount of deflection. The prongs 125 and 126 are configured to help reduce vibration and noise in the pawl 114 by limiting the movement and deflection of the pawl 114 under vibration conditions.

[0169] It should be understood that the above description of the operation of the latch assembly 104 and the door assembly 100 is not limited to any order of steps and that the order of steps shown and described may be varied without departing from the scope and spirit of the present invention.

[0170] Second embodiment

[0171] exist FIG. 15A to FIG. 24B A second embodiment of a door assembly 900 incorporating aspects of the present invention is shown in FIG. The door assembly 900 is similar in structure and function to the Figures 1A to 1C The door assembly 100 of FIG. 1 and only the differences between these door assemblies will be described below. The pawl of the door assembly 900 and the protrusion on the door 902 for supporting the pawl are not shown.

[0172] The latch assembly 904 of the door assembly 900 is mounted to the door 902 to releasably retain the door 902 in a closed position. Fig.16 Depicted is an exploded view of a latch assembly 904 of door assembly 900. The major components of latch assembly 904 are base housing 910, user operated paddle 912, rotor 914, torsion springs 916 and 918, lock cylinder 920, and optionally two pawls (not shown).

[0173] exist Figures 17A-17G The base housing 910 shown in FIG. 1 is similar to the housing 300, and only the major differences between those housings will be described below. An alignment pin 930 protrudes from a rear surface 932 of the housing 910. The pin 930 is aligned along the centerline of the housing 910. The pin 930 is configured to be inserted into a hole 934 ( Fig. 15B ) for alignment purposes.

[0174] There are also two prongs 936 protruding from the rear surface 932 of the housing 910 at the same end as the pin 930. The prongs 936 are located on opposite corners of the rear surface 932. Each prong 936 includes a barb at its free end, and the prongs are configured to snap into a recess 938 provided in the door 902 ( Fig. 15B), so that the fastener 993 (not shown in this figure, but in Fig.25B 902 for retention purposes prior to mounting the base housing 910 to the door 902. Fasteners are guided through holes 940 in the door 902 and threaded into holes 942 in the housing 910 for securing the base housing 910 (and the entire latch assembly 904) to the door 902.

[0175] It is noted that with proper design and control, fasteners can be eliminated from the assembly and the unit can be held in the door by using only the tines.

[0176] A clip 944 in the form of a flexible flap or prong is formed on and extends outwardly from one side of the housing 902. A rib 946 extends outwardly along the centerline of the clip 944. The clip 944 is configured to be inserted into a recess 948 formed on the side of a rectangular recessed area 949 of the door 902. The top end of the recess 948 includes a channel 950 for receiving the rib 946 of the clip 944. During assembly of the latch assembly 904 to the door 902, the engagement between the rib 946 and the channel 950 is used as a locating feature.

[0177] Pin 954 protrudes from opposing side walls 958 and 959 of housing 910. Pin 954 is sized to be received in a blind channel 955 formed in paddle 912 (see FIG. Fig.18B ). A through hole 956 is formed through the side walls 958 and 959 of the housing 910 for receiving a pin 960. Fig.16 As shown, the pin 960 has an annular release portion (or cutout) 962 formed in a central region thereof. In the assembled form of the latch assembly 904, a protrusion 964 extending from the inner surface of the housing 910 is placed in the release portion 962 of the pin 960, and the engagement between the protrusion 964 of the housing 910 and the release portion 962 of the pin 960 holds the pin 960 in the through hole 956 of the housing 910. The pin 960 is positioned to pass through the center of the spiral body of the spring 916, which is used to bias the paddle 912 to the original position.

[0178] Pin 960 may also be retained by other methods not described herein.

[0179] A hole 970 is formed through the housing 910 to receive the lock cylinder 920. Two inwardly extending angled projections 972 are positioned at diametrically opposed locations along the inner circumference of the hole 970. The projections 972 engage surfaces on the lock cylinder 920 and are configured to secure the lock cylinder 920 within the hole 970 while allowing the lock cylinder 920 to rotate within the hole 970.

[0180] The number and pattern of two inwardly extending projections 972 used may be varied as desired to accommodate the details of the lock cylinder design.

[0181] exist Figures 18A-18G The paddle 912 shown in FIG. 1 is similar to the paddle 400, and only the major differences between these paddles will be described below. The paddle 912 includes opposing side walls 973 and 974. Each side wall 973 and 974 defines an arcuate blind channel 955, and each channel 955 is sized to receive one of the pins 954 on the housing 910. Another arcuate channel 976 is defined on each side wall 973 and 974, and each channel 976 is sized to receive one end of a pin 960.

[0182] To assemble the paddle 912 to the housing 910, the pin 954 is inserted into the channel 955 until the hole 956 of the housing 910 is aligned with the arcuate channel 976. Thereafter, the pin 960 is inserted through the channel 976 and the hole 956 until the release portion 962 of the pin 960 engages with the protrusion 964 of the housing 910, thereby capturing the paddle 912 to the housing 910.

[0183] Now go to Figure 22A-22C , Fig.24A and Fig. 24B , the paddle 912 can surround the housing 910 in the closed position ( Fig.22A ) and the open position ( Fig. 22B ). When the paddle 912 pivots from the closed position to the open position, channel 976 slides on pin 960, while channel 955 slides on pin 954. The arc forming the pivot is defined by two separate pins (on each side of the paddle 912) riding in an arc segment around the same center. The arcs of channels 955 and 976 are concentric.

[0184] In the open position of the paddle 912, the pin 960 bears against the end of the channel 976 and the wall 977 ( Fig.18B ) is supported at position 981 on the outer wall 979 of the housing 910 ( Fig. 17B ) on, thereby preventing the paddle 912 from further rotating beyond the open position shown. In other words, in the open position of the paddle 912, further rotation of the paddle 912 is prevented by features located at the opposite ends of the housing 910.

[0185] A shock absorber 983 formed of a soft material such as rubber or plastic is positioned within an aperture formed in the housing 910, and the shock absorber 983 is positioned to contact the underside of the paddle 912 in the closed position of the paddle 912. When the paddle 912 returns to the closed position, the shock absorber 983 reduces the noise generated between the housing 910 and the paddle 912, such as Fig.23A and Fig.23C shown.

[0186] It will be noted that the housing and the bumper form a directed channel or passageway to allow access to the lock retaining contacts as previously described.

[0187] exist Figure 19A-19E The rotor 914 shown in FIG. 5 is similar to the rotor 500, and only the major differences between those rotors will be described below. The rotor 914 includes a body 980 having a circular bottom wall 982. Two arcuate cutouts 984 surround the outer periphery of the wall 982 at diametrically opposed locations. Each cutout 984 includes an enlarged opening 985 for receiving one of the barbs 986 of the housing 910. To assemble the rotor 914 to the housing 910, the barbs 986 are first positioned through the corresponding enlarged opening 985 in the rotor 914, and the rotor 914 is rotated to space the barbs 986 from its opening 985. The barbs 986 retain the rotor 914 to the housing 910.

[0188] The dimensions of the barbs 986 and the associated notches 985 can be formulated so that the orientation of the installation can be controlled. In other words, the dimensions of one barb and one associated notch can be larger than the dimensions of the other pair to prevent the wrong orientation of the installation. In addition, the number of barbs required for installation can be varied.

[0189] An annular wall 987 extends from the bottom side of the bottom wall 982 and defines an inner space 987a in the annular wall 987, in which the distal end of the lock cylinder 920 is positioned. A straight rib 988 is provided on the underside of the wall 982 and is located in the inner space 987a to interact with the post 990 of the lock cylinder 920, as will be described later. An annular channel 987b surrounds the wall 987 and is sized to receive the spring 918.

[0190] exist Fig. 20A and Fig. 20B The lock cylinder 920 shown in FIG. 1 is similar to the lock cylinder 600, and only the main differences between these lock cylinders will be described below. The lock cylinder 920 includes a column 990, which extends from an inner cylinder 994 and can rotate with the inner cylinder 994 (similar to the column 604). The cross-section of the column 990 has a rectangular shape, and a release portion is provided in the column.

[0191] Now turn to Figure 21A-Figure 21C ,exist Fig.21A In the unlocked and closed state of the latch assembly 904 shown, the post 990 of the lock cylinder 920 is spaced apart (in the circumferential direction) from the rib 988 of the rotor 914. Therefore, the paddle 912 and the rotor 914 are free to rotate toward the open position. Fig.21BIn the open and unlocked state of the latch assembly 904 shown, the paddle 912 has been pivoted to the open position and the rotor 914 has been rotated by the paddle 912. In the open position, the posts 990 of the lock cylinder 920 remain spaced apart (in the circumferential direction) from the ribs 988 of the rotor 914. Fig. 21C In the closed and locked state of the latch assembly 904 shown in FIG. 1 , the post 990 of the lock cylinder 920 has been rotated (i.e., by rotating the key in the lock cylinder 920) so that the post 990 bears on the rib 988 of the rotor 914, thereby preventing the rotor 914 from rotating counterclockwise (e.g., Fig. 21C ), which also prevents rotation of the paddle 912 toward the open position.

[0192] Third embodiment

[0193] exist FIG. 25A to FIG. 31F A third embodiment of a door assembly 1000 incorporating aspects of the present invention is shown in FIG. The door assembly 1000 is similar in structure and function to the FIG. 15A to FIG. 24B The door assemblies 900 are described below only those differences between the door assemblies.

[0194] The non-locking latch assembly 1004 of the door assembly 1000 is mounted to the door 1002 to releasably hold the door 1002 in a closed position. The latch assembly 1004 of the door assembly 1000 is mounted to the door 1002 in the same manner as the latch assembly 904.

[0195] from Fig.25C The sequence of assembling the latch assembly 1004 to the door 1002 is shown initially, with the latch assembly 1004 being moved toward the door 1102. Fig.25D , the latch assembly 1004 is tilted (angled) and moved to the door 1002, and the clip 944 of the latch is positioned within the recess 948 in the door 1002, as described above. Fig.25A , the latch assembly 1004 is rotated into the recess of the door 1002 until the clips on the latch assembly 1004 connect to their respective openings (in the door 1002). Fig.25B , fastener 993 is mounted to door 1002 and latch assembly 1004.

[0196] Figure 26A-Figure 26E Depicted is a latch assembly 1004 and two pawls 1006 and 1008 mounted to the latch assembly 1004. The pawls 1006 and 1108 operate in substantially the same manner as the pawls of the latch assembly 104.

[0197] Figure 27-28BA non-locking latch assembly 1004 of the door assembly 1000 is depicted. The main components of the latch assembly 1004 are: a base housing 1010, a user-operated paddle 1012, a rotor 1014, torsion springs 916 and 918, and optionally two pawls (not shown in this figure). Common features between the latch assembly 1004 and the latch assembly 904 will not be described herein.

[0198] Figure 29A-29F The paddle 1012 shown in FIG. 1 is substantially similar to the paddle 912, except that the paddle 1012 includes a square opening 1015 on one side surface thereof. The opening 1015 is Figure 32-Figure 38 1014. The latch assembly 1100 of the fourth embodiment of the present invention is shown in Figure 1002. Although not shown, the opening 1015 in the paddle 1012 may be replaced with a blind cavity, ledge, or bearing surface against which the locking pin may abut without departing from the scope of the present invention. The third embodiment is non-locking, and the opening 1015 does not serve any particular purpose for the non-locking embodiment.

[0199] Figure 30A-Figure 30F The base housing 1010 shown in FIG. 1 is substantially similar to the housing 910, except that the housing 1010 includes a square opening 1016 on one side surface thereof. The square opening 1016 is Figure 32-Figure 38 In addition, the opening 1018 in the housing 1010 is sized to receive (only) different types of lock cylinders in the locking type of the latch assembly. Two outwardly protruding ramps 1020 and 1022 are defined on the top and bottom sides of the housing 1010. The radius of curvature of the ramp 1022 is smaller than the radius of curvature of the ramp 1020. Each of the ramps 1020 and 1022 is configured to interact with a surface or recess formed on the inner side of the paddle 1012 to help guide the rotation of the paddle 1012 around the base housing 1010. As shown Fig.34C As best shown, a groove 1011 is formed on the bottom wall of the housing 1010, which is used to retain the spring tongue, as will be referred to in Figure 32-Figure 38 The locking type of the latch assembly 1100 shown in the fourth embodiment is described.

[0200] exist Figure 31A-Figure 31F Rotor 1014 shown in FIG. 1 is substantially similar to rotor 914 , except that rotor 1014 does not include internal ribs (such as ribs 988 ) configured to interact with a lock.

[0201] In operation, from Fig.25AStarting with the latch assembly 1004 in the closed position shown in FIG. 1 , the user rotates the paddle 1012 in an outward direction to overcome the bias of the spring 916. Fig.25D The paddle 1012 operates in the same manner as described with reference to the second embodiment. When the paddle 1012 is rotated outward, the rounded leg 1020 of the paddle 1012 bears against the bearing surface 1022 of the rotor 1014, thereby causing the rotor 1014 to rotate in a counterclockwise direction (e.g., from the left) against the bias of the spring 916. Fig.25B 1004). As the rotor 1014 rotates, the slots 1024 of the rotor 1014 move over the tines 1026 of the housing 1010. Also, as the rotor 1014 rotates, the pawls 1006 and 1008 move inwardly toward the housing 1010 and disengage from their corresponding strikers (in the vehicle dashboard). In the open position of the latch assembly 1004, the door assembly 1000 can move relative to the opening of the motor vehicle in which the door assembly 1000 is installed.

[0202] When the user releases the paddle 1012, the spring 916 returns the paddle 1012 to the Fig.25A and Fig.28B 1000 is shown in the original position. In addition, due to the bearing engagement between the leg 1020 and the bearing surface 1022 of the rotor 1014, the spring 918 returns the paddle 1012 to the original position. As described above, the paddle 1012 rests on the shock absorber 983 to prevent BSR. When the rotor 1014 rotates in the clockwise direction, the pawls 1006 and 1008 move outward and away from the housing 1010, so that the free ends of the pawls 1006 and 1008 can respectively engage with the striker (not shown) on the opening of the motor vehicle to which the door assembly 1000 is installed. The user then closes the door assembly 1000, thereby concealing the opening in the motor vehicle, and causing the free ends of the pawls 1006 and 1008 to respectively engage with the striker (not shown) on the opening of the motor vehicle.

[0203] Fourth embodiment

[0204] exist Figure 32 to Figure 38 A fourth embodiment of a locking latch assembly 1100 incorporating aspects of the present invention is shown in FIG. The locking latch assembly 1100 may be used with Fig.25A The latch assembly 1100 is similar in structure and function to the FIG. 25A to FIG. 31F The non-locking latch assembly 1004 is different from the non-locking latch assembly 1004 in that the latch assembly 1100 is configured to lock the door 1002 in a closed position.

[0205] The locking latch assembly 1100 generally includes all of the components of the latch assembly 1004 and additionally includes: an electronic lock 1102 for selectively locking and unlocking the latch assembly 1100; and a lock pin 1104 that is moved between a locked position and an unlocked position by the lock 1102 against the bias of a spring tongue 1106.

[0206] The electronic lock 1102 includes a motor housing 1110 that houses an electric motor having an output shaft 1111. A gear 1112 having a plurality of gear teeth is non-rotatably connected to the output shaft 1111 of the motor in a keyed manner so that the gear 1112 rotates with the output shaft 11111. The motor housing 1110 is fixed in a hole 1018 in the housing 1010 by a spring tongue 1019 defined in the interior of the housing 1010. Although not shown, the electronic lock 1102 includes wires for connecting to a power source (e.g., a vehicle battery) in the vehicle. The rotor 1014 has a central opening 1025 through which the wires can pass. The electronic lock 1102 or a receiver unit connected thereto is configured to receive commands wirelessly (e.g., short-range radio transmission, Bluetooth, RFID, etc.) from a key memory (keyfob, remote control key) having a transmitter, however, the lock 1102 can also receive commands through a wired connection in the vehicle. The lock 1102 can also be electrically controlled using a simple switch. The lock 1102 is not visible from the outside of the door assembly.

[0207] The lock 1102 is also more broadly referred to herein as an "actuator" because the lock 1102 can be a button or a lock cylinder that can be manually actuated.

[0208] The motor of lock 1102 has a large gear ratio (e.g., 100:1) so that the system cannot be back-driven. More specifically, the large gear ratio prevents locking pin 1104 from being manually pushed back into housing 1010, thereby unlocking latch assembly 1100 in a manual, unauthorized manner.

[0209] exist FIG. 37A to FIG. 37F The locking pin 1104 shown in FIG. 1 is an elongated body having at least partially a square or rectangular cross-section. Specifically, the locking pin 1104 includes an axially extending first end 1113 having triangular gear teeth 1116 on the side facing the gear 1112. Fig.34A 1102, the gear teeth 1116 are configured to mesh with the gear 1112 of the lock 1102. The axially extending second end 1118 is parallel to and spaced apart from the first end 1113. The shoulder 1115 extends transversely between the ends 1113 and 1118. Two parallel prongs 1117 extend the shoulder 1115 in a direction transverse to the first end 1113 at the intersection of the shoulder 1115 and the first end 1113.

[0210] The second end 1118 of the locking pin 1104 is configured to retain the latch assembly 1100 in the locked configuration when the locking pin 1104 is moved to the extended and locked position. Fig.34A and Fig.34B Specifically, in the locked state of the locking pin 1104, the second end 1118 is positioned to at least partially pass through the hole 1016 in the housing 1010 and the hole 1015 in the paddle 1012. Therefore, the second end 1118 of the locking pin 1104, the hole 1016 in the housing 1010, and the hole 1015 in the paddle 1012 are axially aligned.

[0211] It has been found that compared to conventional locks that act closer to the pivot point of the paddle, the forwardmost edge 1123 of the housing 1010 (see Fig.30F ) (i.e., an edge of the housing 1010 opposite the axis of rotation defined at least in part by the pin 960), engaging the locking pin 1104 with the paddle 1102, increasing the resulting locking load. In other words, the locking strength of the latch assembly 1100 is greater than the locking strength of a conventional paddle lock in which the locking pin engages the paddle near the pivot point of the paddle.

[0212] exist Fig.38 The spring tongue 1106 is shown in FIG. 1 and is made of a thin flexible and elastic material such as metal or plastic. The spring tongue 1106 includes an elongated body having a first end 1120 and a second end 1121, the first end being fixedly mounted in a slot 1011 formed in the housing 1010, the second end 1121 being opposite the first end 1120. The second end 1121 is folded over itself, and a gap is formed between the folds. In the assembled form, as shown in FIG. Fig.33E As best shown, the second end 1121 of the spring tongue 1106 is mounted to the fork 1117 of the locking pin 1104. The spring tongue 1106 is configured to bias the movable locking pin 1104 relative to the fixed housing 1010. Specifically, the spring tongue 1106 is biased to cause the locking pin 1104 to move in a direction that is substantially perpendicular to the locking pin 1104. Fig.34B and Fig.35B 1010 and 1011. The spring tongue 1106 need not be a separate component, but may be co-molded or integrally formed with the housing 1010 or the locking pin 1104. In addition, the spring may also be in other forms, such as a coil spring or a torsion spring.

[0213] FIG. 33A to FIG. 33E The sequential process of assembling the lock 1102, the lock pin 1104, the spring tongue 1106 and the damper 983 into the latch assembly 1100 is shown.

[0214] In operation, from Fig.34A and Fig.34BBeginning in the closed and locked position of the latch assembly 1100 shown, the second end 1118 of the locking pin 1104 is positioned to pass through the hole 1016 in the housing 1010 and at least partially through the hole 1015 in the paddle 1012, thereby preventing a user from rotating the paddle 1012 relative to the housing 1010.

[0215] The user then sends a signal to the lock 1102, which causes the motor of the lock 1102 to rotate the gear 1112 in a clockwise direction (eg, Fig.34A As shown), this causes the locking pin 1104 to translate out of the hole 1015 of the paddle 1012, overcoming the bias of the spring tongue 1106. Fig.35A As depicted in. Once the locking pin 1104 is separated from the hole 1015 of the paddle 1012, the latch assembly 1100 remains in the unlocked position. Then, the user can rotate the paddle 1012 to open the door 1002, as described with reference to the third embodiment.

[0216] To lock the door 1002, the user sends a signal to the lock 1102, which causes the motor of the lock 1102 to rotate the gear 1112 in a counterclockwise direction (eg, Fig.34A ), which causes the locking pin 1104 to translate into the hole 1015 of the paddle 1012 against the bias of the spring tongue 1106. Once the locking pin 1104 is positioned in the hole 1015 of the paddle 1012, the latch assembly 1100 remains in the locked position.

[0217] It should be noted that the lock 1102 and the lock pin 1104 are separated from the pawls 1006, 1008 and the rotor 1014 so that the pawls 1006, 1008 can translate even when the paddle 1012 is locked by the lock pin 1104. Therefore, the door 1002 can be moved to the closed position even when the latch assembly 1100 is locked. This feature prevents damage to the latch assembly 1100 in the event that the door 1002 is closed while the latch assembly 1100 is locked. It is also noted that the lock pin 1104 has a limited number of teeth (e.g., one) so that the gear teeth 1116 do not mesh with the gear 1112 at the moment when the lock pin 1104 has reached the locked or unlocked position. Instead, the gear 1112 can continue to rotate without causing damage to the gear 1112 or the lock pin 1104. However, at the moment when the rotation of gear 1112 stops, spring tongue 1106 pulls locking pin 1104 toward the center of gear 1112 to engage teeth 1116 with teeth of gear 1112. Therefore, when the driving direction of gear 1112 is reversed, locking pin 1104 and gear 1112 are engaged so that locking pin 1104 can move in the opposite direction.

[0218] The bias of the spring tongue 1106 also protects against gear stripping or motor stalling. The ability of the teeth 1116 on the locking pin 1104 to disengage the gear 1112 on the motor prevents an overload condition of the locking pin 1104 at the end of its travel. The spring tongue 1106 ensures that the teeth 1116 re-engage the gear 1112 for reverse actuation as desired.

[0219] Fifth embodiment

[0220] Figure 45A-Figure 45D and Fig.46 Depicts a schematic diagram for an AND gate component such as Figures 25A-25D A fifth exemplary embodiment of a locking latch assembly 1800 for use with a door assembly (or similar) as shown in FIG. The locking latch assembly 1800 is generally similar to Fig.32 The latch assembly 1100 of FIG. 1 is shown in FIG. 1 , and only two main differences between them will be described below. The common components between these latch assemblies share the same reference numerals.

[0221] The paddle 1808 of the latch assembly 1800 includes an aperture 1809 through which a lock cylinder (not shown) is positioned to lock or unlock the latch assembly 1800. Fig. 6A and 6B Further details about the lock cylinder are described.

[0222] Figure 47-Figure 52 Depicted for assembly Fig.45A 1806, rotor 1804, and base housing 1802 of latch assembly 1800. Fig.47 and Fig.48 Initially, the spring 1806 is mounted to the rotor 1804 by positioning the coiled portion of the spring 1806 into an annular recess 1810 formed on one side of the rotor 1804. One free end 1811 of the spring 1806 is positioned into a first spring mounting recess 1812 extending tangentially from the annular recess 1810. Referring now to Fig.49 , the other free end 1813 of the spring 1806 is wound around the rotor 1804, thereby tightening the coiled portion of the spring 1806, and the other free end is inserted into a second spring mounting recess 1814 formed on the side surface of the rotor 1804. The rotor 1804 and the spring 1806 now constitute a subassembly.

[0223] Now refer to Fig.50 and Fig.51 , by positioning the barbs 1816 on the housing 1802 into corresponding slots 1818 formed in the rotor 1804 (similar to Fig. 11CThe subassembly of rotor 1804 and spring 1806 is mounted to the underside of base housing 1802. Fig.52 , the rotor 1804 is rotated in the direction indicated by the arrow until one of the barbs 1816 on the housing 1802 snaps onto a protruding surface 1820 formed on the rotor 1804. Thereafter, the subassembly of the rotor 1804 and the spring 1806 is rotatably connected to the housing 1802. The free end 1813 of the spring 1806 is positioned against a stop 1822 formed on the outer surface of the housing 1802. The spring 1806 biases the rotor 1804 to move in a direction in relation to the housing 1802. Fig.52 Rotate in the direction opposite to the direction of the arrow shown.

[0224] Now go to Figure 53-54B The base housing 1802 of the locking latch assembly 1800 includes a rotation limiter 1840 extending from the axial side thereof. Each rotation limiter 1840 is a surface that is configured to engage with a corresponding surface 1842 formed on the paddle 1808 to limit the paddle 1808 from rotating beyond Fig.54B The open position shown. The surface 1842 on the paddle is heel-shaped and is located inside the hollow paddle 1808 and hidden from view. It should be noted that other components of the locking latch assembly 1800 that act in coordination with the rotation limiter 1840 can also prevent the paddle 1808 from rotating beyond Fig.54B Shown in open position.

[0225] Sixth embodiment

[0226] Fig.55 is used with Figure 25A-Figure 25D a bottom view of a sixth exemplary embodiment of a locking latch assembly 1900 for use with a door assembly, and Fig.56A and Fig.56B The pawl 1908 is shown mounted to the latch assembly 1900. The latch assembly 1900 is generally similar to Fig.45A The latch assemblies 1800 are identical and only the main differences between them will be described below.

[0227] The rotor 1902 of the latch assembly 1900 includes four crescent-shaped recesses 1904a-1904d (individually or collectively referred to as recesses 1904) defined on the periphery of the rotor 1900. The recesses 1904a-1904d are evenly spaced approximately ninety degrees around the periphery of the rotor 1902. Each recess 1904 is configured to releasably couple to one of the posts 120 and 127 of the pawls 112 and 114, respectively, for example, as described above with reference to Figure 5B described.

[0228] It should be noted that the rotor 1804 of the latch assembly 1800 may be provided with recesses 1904a and 1904b, however, unlike the rotor 1804, the rotor 1902 further includes two additional recesses 1904c and 1904d. The recesses 1904c and 1904d are provided as an alternative to the use of the recesses 1904a and 1904b. More specifically, when it is desired to be in a "side pull" arrangement (similar to Figure 1A When the locking latch assembly 1900 is used in a "vertical lift" arrangement, the two pawls are connected to the recesses 1904a and 1904b. Alternatively, when it is desired to use the locking latch assembly 1900 in a "vertical lift" arrangement, as shown in FIG. Fig.56A and Fig.56B As shown, the two pawls 1908 are connected to the recesses 1904c and 1904d. Fig.56A and Fig.56B , the pawls are shown mounted to recesses 1904c and 1904d (only), and the pawls are shown rotating rotor 1902 in these views.

[0229] It should be noted that the number of recesses 1904 and the spacing between them can vary. For example, rotor 1902 can include only two recesses 1904 and 1904, and the orientation of the pawl can be changed to switch between the vertical lift and the side pull arrangement.

[0230] It should also be noted that any of the latch assemblies shown herein may be used in either a side-pull configuration or a vertical lift configuration.

[0231] Alternative arrangements for actuators

[0232] Figure 39-Figure 44 An alternative arrangement for an actuator that moves a locking pin or locking pin-like member is shown.

[0233] Fig.39 Shows the lock Fig.32 Schematic diagram of an alternative arrangement of a paddle 1012 of a locking latch assembly, wherein the alternative arrangement includes a motor-driven clock spring 1200. The clock spring 1200 is wound or unwound by a shaft 1202 of a motor. When the clock spring 1200 is unwound, the end 1204 is positioned to pass through the opening 1016 of the housing 1010 and at least partially through the opening 1015 of the paddle 1012, thereby locking the paddle 1012 in a fixed position. Rotating the shaft 1202 of the motor in the opposite direction retracts the end 1204 of the paddle 1012 from the opening 1015 of the paddle 1012, thereby releasing and unlocking the paddle 1012. Shown is the locked position of the paddle 1012.

[0234] Fig.40 Shows the lock Fig.321012 of a locking latch assembly, wherein the alternative arrangement includes a motor-driven eccentric member 1302. The eccentric member 1302 is rotated by a shaft 1202 of a motor 1304 on which the eccentric member is non-rotatably mounted. To lock the paddle 1012 in a fixed position, the eccentric member 1302 is rotated so that the eccentric portion 1306 having a large diameter is positioned through the opening 1016 of the housing 1010 and at least partially through the opening 1015 of the paddle 1012, thereby preventing the paddle 1012 from moving relative to the housing 1010. To unlock the paddle 1012, the eccentric member 1302 is rotated so that the eccentric portion 1306 having a large diameter is disengaged from the opening 1015 of the paddle 1012, thereby allowing the paddle 1012 to move relative to the housing 1010.

[0235] Fig.41 Shown for Fig.40 The alternative motor-driven eccentric member of the arrangement includes a motor-driven crescent cam 1402. The crescent cam 1402 is driven by a gear 1404, and the crescent cam 1402 replaces Fig.40 The eccentric member 1302 shown in FIG. 1 and the gear 1404 can be connected to Fig.40 Motor 1304.

[0236] Fig.42 Shows the lock Fig.32 1012 , wherein the alternative arrangement includes a motor driven rack and pinion. A gear 1502 powered by an output shaft of a motor (not shown) meshes with gear teeth 1505 on a top rack 1504 and gear teeth on a bottom rack 1506. The bottom rack 1506 is optional. To lock the paddle 1012 in a fixed position, the gear 1502 is rotated so that the top rack 1504 moves through the opening 1016 of the housing 1010 and at least partially through the opening 1015 of the paddle 1012, thereby preventing the paddle 1012 from moving relative to the housing 1010. To unlock the paddle 1012, the gear 1502 is rotated in the opposite direction so that the top rack 1504 moves out of the opening 1015 of the paddle 1012, thereby allowing the paddle 1012 to move relative to the housing 1010.

[0237] Fig.43 Shows the lock Fig.32Schematic diagram of yet another alternative arrangement of a paddle of a locking latch assembly of , wherein the alternative arrangement includes a motor driven and spring loaded rack and pinion. A gear 1602 powered by an output shaft of a motor (not shown) engages with gear teeth 1605 on a lower surface of a rack 1604. Two springs 1608a and 1608b biasing the rack 1604 in opposite directions bias the rack 1604 to a center position. One end of each spring 1608a and 1608b is mounted to the rack 1604, and the opposite end of each spring 1608a and 1608b is mounted to a stationary fixed point. To lock the paddle 1012 in a fixed position, the gear 1602 is rotated so that the rack 1604 overcomes the bias of the spring 1608a and moves through the opening 1016 of the housing 1010 and at least partially through the opening 1015 of the paddle 1012, thereby preventing the paddle 1012 from moving relative to the housing 1010. To unlock the paddle 1012, the gear 1602 is rotated in the opposite direction so that the rack 1604 moves out of the opening 1015 of the paddle 1012 against the bias of the spring 1608b, thereby allowing the paddle 1012 to move relative to the housing 1010. The rack 1604 has no teeth over the length 1609 on either side of the teeth 1605 to prevent damage to the rack 1604.

[0238] Fig.44 Shows the lock Fig.32 Schematic diagram of yet another alternative arrangement of a paddle for a locking latch assembly. Fig.44 The arrangement shown in Fig.43 The arrangement shown is substantially the same except that Fig.44 The arrangement shown in is biased by flexible movable springs 1702a and 1702b. More specifically, movable springs 1702a and 1702b extend from the top surface of rack 1701. The interaction between movable springs 1702a, 1702b and fixed posts 1704a, 1704b, respectively, centers rack 1701. More specifically, when gear 1705 rotates rack 1701 toward the locked position, movable spring 1702b deflects against fixed post 1704b, and when gear 1705 rotates in the opposite direction, movable spring 1702b returns to its initial form. Conversely, when gear 1705 rotates rack 1701 toward the unlocked position, movable spring 1702a deflects against fixed post 1704a, and when gear 1705 rotates in the opposite direction, movable spring 1702a returns to its initial form.
