[0050] FIG. 1 illustrates a carriage system 100 according to an embodiment. The carriage system 100 may include a carriage assembly 102 which is mounted to an accessory 104. In the illustrated example of FIG. 1, the accessory 104 is a grill. It should be understood that the accessory 104 may be any of a multitude of accessories (e.g., tools, baskets, lighting sources, coolers, etc.). The carriage assembly 102 may include a tabletop assembly 106 connected to a lower shelf assembly 108 via a linkage assembly 110. A pair of rear wheels 112 and a pair of front wheels 114 may support the linkage assembly 110. In the illustrated example of FIG. 1, the carriage system 100 is in a deployed configuration 116.

[0051] The tabletop assembly 106 may include a first support beam 120 connected to a second support beam 122 via a first crossbar 124 and a second crossbar 126. In some embodiments, the second crossbar 126 extends through the first support beam 120 and the second support beam 122. The first support beam 120 and the second support beam 122 may support a tabletop 128. In some embodiments, the tabletop 128 is ellipsoid, ovoid, and / or rounded, though any number of shapes are foreseeable. The tabletop assembly 106 is preferably articulably connected to the linkage assembly 110, as will be explained in greater detail below.5HB: 4917-3871-6768.1Aty. Docket No.535634-266

[0052] The linkage assembly 110 may include a first support leg 130 and a second support leg 132 pivotably connected to the first support beam 120 and the second support beam 122, respectively. The first support leg 130 can be connected to the second support leg 132 via a third crossbar 134. Additionally, the linkage assembly 110 can include a third support leg 136 and a fourth support leg 138. The third support leg 136 may include a first pivot end 140 and a first fixed end 142. The fourth support leg 138 may include a second pivot end 144 and a second fixed end 146. The third support leg 136 may be pivotably connected to the first support leg 130 at the first pivot end 140. The fourth support leg 138 may be pivotably connected to the second support leg 132 at the second pivot end 144. The first fixed end 142 may be connected to the second fixed end 146 via a fourth crossbar 148. The first support leg 130 may be further connected to the second support leg 132 via a fifth crossbar 150 located along the first support leg 130 and the second support leg 132 between the second crossbar 126 and the third crossbar 134. The first support leg 130 and the second support leg 132 may be substantially parallel to one another. A first distance DI between the first pivot end 140 and the second pivot end 144 is preferably less than a second distance D2 between the first fixed end 142 and the second fixed end 146.

[0053] The linkage assembly 110 further may include a first support arm 160 and a second support arm 162. The first support arm 160 may be pivotably connected to the first support beam 120 and the first support leg 130. The second support arm 162 may be pivotably connected to the second support beam 122 and the second support leg 132. A kickstand 164 and a first foot 166 preferably extend outwardly from the first support leg 130 and the second support leg 132, respectively. In some embodiments, the kickstand 164 may be rectilinear. In some embodiments, the kickstand 164 may include rounded corners. Additionally, the first support arm 160 may be connected to the second support arm 162 via a sixth crossbar 168. The rear wheels 112 are preferably rotatably connected to the first support leg 130, the second support leg 132, and / or the third crossbar 134. In some embodiments, the third crossbar 134 forms an axle for the rear wheels 112. Further, the front wheels 114 may be casters such that they are swivelably connected to the third support leg 136, the fourth support leg 138, and / or the fourth crossbar 148. In some embodiments, the front wheels 114 include integral brakes.

[0054] The lower shelf assembly 108 may include a forward portion 170 pivotably connected to a rear portion 172 and the fourth crossbar 148. The rear portion 172 may further be pivotably connected to the fifth crossbar 150. A front edge 174 of the forward portion 170 is preferably wider than the rear portion 172. Thus, the forward portion 170 may be at least partially tapered. In the deployed configuration 116, the lower shelf assembly 108 is preferably6HB: 4917-3871-6768.1Aty. Docket No.535634-266 substantially parallel to the tabletop 128, and the forward portion 170 is unfolded from and substantially colinear or coplanar with the rear portion 172.

[0055] The carriage assembly 102 further may include a latch assembly 180 configured to retain and pivotably release the tabletop assembly 106 relative to the linkage assembly 110. Thus, by actuating the latch assembly 180, the carriage system 100 may be selectively moved into and released from the deployed configuration 116, as will be explained in greater detail below.

[0056] Referring to FIG. 2, the latch assembly 180 may include a latch 182 pivotably connected to the second support leg 132 and a first rod 184. The latch assembly 180 further may include a lever plate 186 pivotably connected to a pivot end 188 of the second support leg 132, the first rod 184, and a second rod 190. The second rod 190 is preferably slidably supported by a slide bracket 192 mounted to the second support beam 122. The second rod 190 may include a pulling actuator 194 such as a pull tab, a squeezable handle or trigger, or another suitable actuator. The pulling actuator 194 may enable a user to manually pull or otherwise move the second rod 190. In some embodiments, one or more pull wires or cables may be connected between latch 182 and the pulling actuator 194. The pull cable(s) may be provided in lieu of the first rod 184 and the second rod 190. In some embodiments, a first pull cable may be connected between the lever plate 186 and the latch 182 in lieu of the first rod 184 and a second pull cable may be connected between the lever plate 186 and the pulling actuator in lieu of the second rod 190. In some embodiments, a single pull cable may be connected between the pulling actuator and the latch 182 and may be provided in lieu of the first rod 184, the second rod 190, and the lever plate 186.

[0057] The first support leg 130 and the second support leg 132 may define a first slot 200 and a second slot 202, respectively. The sixth crossbar 168 is preferably slidably received in the first support leg 130 and the second support leg 132 via the first slot 200 and the second slot 202, respectively. When the carriage system 100 is in the deployed configuration 116, a hook portion 204 of the latch 182 may catch and retain the sixth crossbar 168. Thus, the latch 182 may selectively prevent the sixth crossbar 168 from sliding along the first slot 200 and the second slot 202.

[0058] In operation, when the second rod 190 is pulled, e.g., via the pulling actuator 194, in a first direction 206 outwardly away from the second support leg 132, tension may be applied to a lever arm 208 of the latch 182 via the second rod 190, the lever plate 186, and the first rod 184. More specifically, the second rod 190 preferably pulls on a first lever branch 210 of the lever plate 186, thus pivoting the lever plate 186 relative to the second support leg 132.7HB: 4917-3871-6768.1Aty. Docket No.535634-266As the lever plate 186 pivots, a second lever branch 212 of the lever plate 186 may pull on the first rod 184. The first rod 184 may then pull on the lever arm 208, thus pivoting the latch 182 relative to the second support leg 132. In some embodiments, movement or pivoting of the latch 182 may be actuated via one or more pull cables connected between the pulling actuator 194 and the latch 182. For example, a second pull cable connected between the pulling actuator 194 and the lever plate 186 may be pulled outwardly via the pulling actuator 194, causing the lever plate 186 to pivot. A first pull cable connected between the lever plate 186 and the latch 182 may be pulled via pivoting of the lever plate 186 to cause the latch 182 to pivot. In some embodiments, a single pull cable may be provided that can cause the latch 182 to pivot when pulled outwardly via the pulling actuator 194.

[0059] As the latch 182 pivots, the hook portion 204 may move away from and release the sixth crossbar 168 so that it can slide along the first slot 200 and the second slot 202. Thus, the first support arm 160 and the second support arm 162 are preferably released to pivot relative to the first support beam 120 and the second support beam 122, respectively. Consequently, the first support leg 130 and the second support leg 132 are preferably released to pivot relative to the first support beam 120 and the second support beam 122, respectively.

[0060] Further in operation, as the sixth crossbar 168 slides toward the latch 182, the sixth crossbar 168 may contact and slide along a ramp portion 214 of the latch 182, thus pivoting the latch 182 relative to the second support leg 132. When the sixth crossbar 168 slides toward the lever arm 208 and beyond the ramp portion 214, the latch 182 preferably snapably pivots back toward the sixth crossbar 168, thus catching the sixth crossbar 168 in the hook portion 204. In some embodiments, the latch assembly 180 is spring-loaded to return to a retaining position 216 in which the hook portion 204 overshadows the second slot 202.

[0061] Referring to FIG. 3, when the carriage system 100 is in a first intermediate configuration 220, the first support arm 160 and the second support arm 162 are pivoted relative to, and align with, the first support beam 120 and the second support beam 122, respectively. Additionally, in the first intermediate configuration 220, the first support beam 120 and the first support arm 160 may each pivot relative to, and align with, the first support leg 130 and the second support beam 122 and the second support arm 162 may each pivot relative to, and align with, the second support leg 132. Movement of the sixth crossbar 168 along the first slot 200 and the second slot 202 described above with reference to FIG. 2 may allow the carriage system 100 to move between the deployed configuration 116 of FIG. 1 and the first intermediate configuration 220 of FIG. 3. Moreover, as the sixth crossbar 168 moves along the first slot 200 and the second slot 202, the pivoting movement of the first support beam 120,8HB: 4917-3871-6768.1Aty. Docket No.535634-266 the second support beam 122, the first support arm 160, and the second support arm 162 allows the tabletop assembly 106 to pivot relative to the first support leg 130 and the second support leg 132 to move the carriage system 100 between the deployed configuration 116 and the first intermediate configuration 220.

[0062] Referring to FIG. 4, when the carriage system 100 is in a second intermediate configuration 230, the lower shelf assembly 108 is preferably folded. More specifically, the third support leg 136 is pivoted relative to the first support leg 130 via a first pivot lobe 232 extending from the first support leg 130. Similarly, the fourth support leg 138 is pivoted relative to the second support leg 132 via a second pivot lobe 234 extending from the second support leg 132. Thus, in the second intermediate configuration 230, the third support leg 136 and the fourth support leg 138 may contact and / or may be substantially parallel with the first support leg 130 and the second support leg 132, respectively. In the second intermediate configuration 230, the forward portion 170 and the rear portion 172 of the lower shelf assembly 108 are preferably folded to contact one another and / or are substantially parallel. Further, in the second intermediate configuration 230, the forward portion 170 and the rear portion 172 preferably nest between the third support leg 136 and the fourth support leg 138. Additionally, in the second intermediate configuration 230, the fourth crossbar 148 may contact, and / or may be substantially perpendicular with, the first support leg 130 and the second support leg 132. Also, in the second intermediate configuration 230, the rear wheels 112 may nest between the front wheels 114.

[0063] In some embodiments, the carriage system 100 may include an actuator that may be manually actuated via the user to move the carriage system 100 to the second intermediate configuration 230. The actuator for the second intermediate configuration may be a different actuator from the pulling actuator 194. In some embodiments, the carriage system 100 includes a lower actuator, e.g., a pedal or kickplate, that can be actuated via a user’s foot for moving the carriage system 100 to the second intermediate configuration 230. Such a lower actuator may be positioned proximate, and / or may extend from, the lower shelf assembly 108 in some embodiments.

[0064] The carriage system 100 may be moved between the deployed configuration 116 of FIG. 1, the first intermediate configuration 220 of FIG. 3, and the second intermediate configuration 230 in any order. For example, the carriage system 100 may be moved from the deployed configuration 116 to the first intermediate configuration 220 and then to the second intermediate configuration 230. Additionally or alternatively, the carriage system 100 may be9HB: 4917-3871-6768.1Aty. Docket No.535634-266 moved from the deployed configuration 116 to the second intermediate configuration 230 and then to the first intermediate configuration 220.

[0065] Referring to FIG. 5, the carriage system 100 may be placed into a collapsed configuration 240, which is a combination of the first intermediate configuration 220 of FIG. 3 and the second intermediate configuration 230 of FIG. 4. When the carriage system 100 is in the collapsed configuration 240, the first support arm 160 is preferably pivoted relative to and aligns with the first support beam 120. Additionally, in the collapsed configuration 240, the first support beam 120 is also preferably pivoted relative to and aligns with the first support leg 130. Further, in the collapsed configuration 240, the third support leg 136 may be pivoted relative to the first support leg 130 via the first pivot lobe 232. Thus, in the collapsed configuration 240, the third support leg 136 preferably contacts and / or is substantially parallel with the first support leg 130. Additionally, in the collapsed configuration 240, the fourth crossbar 148 may contact, and / or may substantially be perpendicular with, the first support leg 130. Also, in the collapsed configuration 240, the rear wheels 112 may nest between the front wheels 114. Further, in the collapsed configuration 240, a first plane Pl defined by a first lower edge 242 of the first foot 166 and a second lower edge 244 along a circumference C of the rear wheels 112 is preferably substantially parallel with the first support beam 120, the first support leg 130, and / or the third support leg 136. Also, in the collapsed configuration 240, a first rear edge 246 of the kickstand 164 and a second rear edge 248 along the circumference C may define an offset distance O.

[0066] When the carriage system 100 is in a collapsed configuration 240, the second support arm 162 may be pivoted relative to and aligns with the second support beam 122 (as shown in FIG. 3). Additionally, in the collapsed configuration 240, the second support beam 122 may also be pivoted relative to and align with the second support leg 132. Further, in the collapsed configuration 240, the fourth support leg 138 may be pivoted relative to the second support leg 132 via the second pivot lobe 234. Thus, in the collapsed configuration 240, the fourth support leg 138 preferably contacts and / or is substantially parallel with the second support leg 132. Additionally, in the collapsed configuration 240, the fourth crossbar 148 preferably contacts and / or is substantially perpendicular with the second support leg 132.

[0067] When the carriage system 100 is in the collapsed configuration 240, the lower shelf assembly 108 may be folded, as shown in FIG. 4. More specifically, the forward portion 170 and the rear portion 172 of the lower shelf assembly 108 may be folded to contact one another and / or are substantially parallel. Further, in the collapsed configuration 240, the10HB: 4917-3871-6768.1Aty.

[0071] The linkage assembly 410 may include the first support leg 130 and the second support leg 132 pivotably connected to the first support beam 420 and the second support beam 422, respectively. The first support leg 130 may be connected to the second support leg 132 via the third crossbar 134. Additionally, the linkage assembly 410 may include a third support leg 436 and the fourth support leg 438. The third support leg 436 may include a first pivot end 440 and a first fixed end 442. The fourth support leg 438 may include a second pivot end 444 and a second fixed end 446. The third support leg 436 is preferably pivotably connected to the first support leg 130 at the first pivot end 140. The fourth support leg 438 is preferably pivotably connected to the second support leg 132 at the second pivot end 444. The first fixed11HB: 4917-3871-6768.1Aty. Docket No.535634-266 end 442 is preferably connected to the second fixed end 446 via the fourth crossbar 148. As above, the first support leg 130 may be further connected to the second support leg 132 via the fifth crossbar 150 located along the first support leg 130 and the second support leg 132 between the second crossbar 426 and the third crossbar 134. The first support leg 130 and the second support leg 132 are preferably substantially parallel to one another. Similarly, the third support leg 436 and the fourth support leg 438 are preferably substantially parallel to one another.

[0072] The linkage assembly 410 further may include the first support arm 160 and the second support arm 162. The first support arm 160 may be pivotably connected to the first support beam 420 and the first support leg 130. The second support arm 162 may be pivotably connected to the second support beam 422 and the second support leg 132. A kickstand 464 and the first foot 166 may extend from the first support leg 130 and the second support leg 132. In some embodiments, the kickstand 464 may be at least partially rounded, ovoid, and / or elliptical. Additionally, the first support arm 160 may be connected to the second support arm 162 via the sixth crossbar 168. The rear wheels 412 are preferably rotatably connected to the first support leg 130, the second support leg 132, and / or the third crossbar 134. In some embodiments, the third crossbar 134 forms an axle for the rear wheels 412. Further, the front wheels 414 may be casters and are swivelably connected to the third support leg 436, the fourth support leg 438, and / or the fourth crossbar 148. In some embodiments, the front wheels 414 include integral brakes.

[0073] The lower shelf assembly 408 may include a forward portion 470 pivotably connected to a rear portion 472 and the fourth crossbar 148. The rear portion 472 may be further pivotably connected to the fifth crossbar 150. The forward portion 470 and the rear portion 472 are preferably substantially identical. A kickplate 474 may extend from the forward portion 470 beyond the fourth crossbar 148. In the deployed configuration 416, the forward portion 470 is preferably unfolded from and substantially colinear or coplanar with the rear portion 472.

[0074] The carriage assembly 402 further may include a latch assembly 480 configured to retain and pivotably release the tabletop assembly 406 relative to the linkage assembly 410. Thus, by actuating the latch assembly 480, the carriage system 400 may be selectively moved into and released from the deployed configuration 416, as will be explained in greater detail below.

[0075] Referring to FIG. 8, in a separated configuration 418, the accessory 404 is removed from the tabletop 428, which defines keyhole openings 476. Each keyhole opening12HB: 4917-3871-6768.1Aty. Docket No.535634-266476 may include a hole portion 478 and a slot portion 482. The slot portion 482 is preferably narrower than the hole portion 478. Further, the brackets 432 may be connected to the accessory 404. The fasteners 430 may extend through the brackets 432. More specifically, to move from the deployed configuration 416 of FIG. 7 to the separated configuration 418, the fasteners 430 may be loosened, the accessory 404 may be translated across the tabletop 428 to shift the fasteners 430 within the keyhole openings 476, and the accessory 404 may be lifted away from the carriage assembly 402, as indicated by arrow 488. It should be appreciated that the fasteners 430 preferably remain in the brackets 432 in the separated configuration 418.

[0076] Referring to FIG. 9, the latch assembly 480 is mounted to the tabletop 428 via a slider bracket 490, which defines a slot 492. A shuttle 494 may be slidably engaged with the slider bracket 490. More specifically, a first tab 496 of the shuttle 494 may extend through and be captured in the slot 492. Thus, the first tab 496 preferably slidably engages the slider bracket 490 and limits movement of the shuttle 494 relative to the tabletop 428. The shuttle 494 may include a second tab 498 configured to be pulled by a user. Pulling the shuttle 494 outwardly relative to the slider bracket 490 preferably actuates the latch assembly 480.

[0077] Referring to FIG. 10, in some embodiments, the fastener 430 extends through the bracket 432 and may include a bolt 500 threadably engageable with a nut 502, e.g., a wingnut. The bolt 500 may include a shank 504 and a head 506. The head 506 is preferably smaller in diameter than the hole portion 478 and wider than the slot portion 482 (shown in FIG. 8). Thus, when the shank 504 is in the slot portion 482, the fastener 430 may be retained in the tabletop 428 (shown in FIG. 8). Further, when the shank 504 is in the hole portion 478, the head 506 may pass through the hole portion 478 and the fastener 430 may be removed from the tabletop 428 (shown in FIG. 8). Additionally, the fastener 430 may remain in the bracket 432 when the accessory 404 is removed from the tabletop 428 (shown in FIG. 8). The fastener 430 may extend through a foot portion 508 of the bracket 432. A connector portion 510 preferably extends from the foot portion 508 and connects to the accessory 404 (shown in FIG. 8).

[0078] Referring to FIG. 11, when the carriage system 400 is in a first intermediate configuration 520, the first support arm 160 and the second support arm 162 may be pivoted relative to and align with the first support beam 420 and the second support beam 422, respectively. Additionally, in the first intermediate configuration 520, the first support beam 120 and the second support beam 122 may also be pivoted relative to and align with the first support leg 130 and the second support leg 132, respectively.13HB: 4917-3871-6768.1Aty. Docket No.535634-266

[0079] The carriage system 400 may be movable from the deployed configuration 416 of FIG. 7 to the first intermediate configuration 520 via actuation of the latch assembly 480. For example, the shuttle 494 may be operable as a pulling actuator that causes the latch assembly 480 to selectively allow or prevent pivoting movement of the first support beam 420, the second support beam 422, the first support arm 160, and the second support arm 162 relative to the support legs 130, 132. The latch assembly 480 may operate similar to the latch assembly 180 described above, e.g., with reference to FIG. 2. Further, by actuating and / or pushing the kickplate 474 (e.g., via a user’s foot) away from the tabletop 428, the carriage system 400 may be selectively moved into one or more additional configurations, as will be explained in greater detail below.

[0080] Referring to FIG. 12, when the carriage system 400 is in a second intermediate configuration 530, the lower shelf assembly 408 is at least partially folded. More specifically, the third support leg 436 may be pivoted relative to the first support leg 130 via the first pivot lobe 232 extending from the first support leg 130. Similarly, the fourth support leg 438 may be pivoted relative to the second support leg 132 via the second pivot lobe 234 extending from the second support leg 132. In the second intermediate configuration 230, the forward portion 470 and the rear portion 472 of the lower shelf assembly 408 pivot relative to another. Additionally, in the second intermediate configuration 230, the forward portion 470 and the rear portion 472 may pivot relative to the fourth crossbar 148 and the fifth crossbar 150.

[0081] In some embodiments, at least one biasing element, such as a torsion spring, may be operably coupled to at least one of the third and fourth support legs 436, 438 proximate the respective pivot lobes 232, 234. For example, a biasing element, e.g., a torsion spring, may be operably coupled between the third support leg 436 and the first pivot lobe 232. Additionally or alternatively, a biasing element, e.g., a torsion spring, may be operably coupled between the fourth support leg 438 and the second pivot lobe 234. The biasing element(s) may be operable to bias the support legs 436, 438 away from the first support leg 130 and the second support leg 132, respectively. In this way, the biasing element(s) may provide a biasing force that urges the carriage system 400 from the second intermediate configuration 530 to the deployed configuration 416 of FIG. 7, at least with respect to the lower shelf assembly 408. At least one retaining member or catch 542, e.g., at least one spring clip, may engage at least one of the third and fourth support legs 436, 438 to releasably retain the lower shelf assembly 408 in the second intermediate configuration 530. The at least one catch 542 may extend from at least one of the first and second support legs 130, 132. When the at least one catch 542 is released,14HB: 4917-3871-6768.1Aty. Docket No.535634-266 the lower shelf assembly 408 may be urged toward the deployed configuration 416 via the at least one biasing element.

[0082] Referring to FIG. 13, the carriage system 400 may be placed into a collapsed configuration 540. When the carriage system 400 is in the collapsed configuration 540, the first support arm 160 is pivoted relative to and aligns with the first support beam 420. Additionally, in the collapsed configuration 540, the first support beam 420 is also preferably pivoted relative to and aligns with the first support leg 130. Further, in the collapsed configuration 540, the third support leg 436 is preferably pivoted relative to the first support leg 130 via the first pivot lobe 232. Also, the catch 542 extending from the first support leg 130 may snapably receive and retain the third support leg 436. In some embodiments, the catch 542 snaps onto a button 544 protruding from the third support leg 436. Thus, in the collapsed configuration 540, the third support leg 436 may contact and / or may be substantially parallel with the first support leg 130. Additionally, in the collapsed configuration 540, the fourth crossbar 148 may contact and / or may be substantially perpendicular with the first support leg 130. Also, in the collapsed configuration 540, the rear wheels 412 preferably nest between the front wheels 414. Further, in the collapsed configuration 540, a first plane Pl defined by the first lower edge 242 of the first foot 166 and a second lower edge 546 of the rear wheels 412 may be substantially parallel with the first support beam 420, the first support leg 130, and / or the third support leg 436. Also, in the collapsed configuration 540, a first rear edge 548 of the kickstand 464 and a second rear edge 550 of the rear wheels 412 may define an offset distance O.

[0083] When the carriage system 400 is in the collapsed configuration 540, the second support arm 162 may be pivoted relative to, and aligns with, the second support beam 422. Additionally, in the collapsed configuration 540, the second support beam 422 also may be pivoted relative to, and aligns with, the second support leg 132. Further, in the collapsed configuration 540, the fourth support leg 438 is preferably pivoted relative to the second support leg 132 via the second pivot lobe 234. In some embodiments, a catch 542 extending from the second support leg 132 may snapably receive and retain the fourth support leg 438. Thus, in the collapsed configuration 540, the fourth support leg 438 preferably contacts and / or is substantially parallel with the second support leg 132. Additionally, in the collapsed configuration 540, the fourth crossbar 148 may contact and / or may be substantially perpendicular with the second support leg 132. Thus, the first support arm 160 and the second support arm 162 may nest between the first support leg 130 and second support leg 132.15HB: 4917-3871-6768.1Aty. Docket No.535634-266Similarly, the first support leg 130 and the second support leg 132 may nest between the first support beam 420 and the second support beam 422.

[0084] When the carriage system 400 is in the collapsed configuration 540, the lower shelf assembly 408 is folded. More specifically, the forward portion 470 and the rear portion 472 of the lower shelf assembly 408 may contact one another and / or may be substantially parallel. Further, in the collapsed configuration 540, the forward portion 470 and the rear portion 472 may nest between the third support leg 436 and the fourth support leg 438.

[0085] The latch assembly 480 further may include a lever plate 486 pivotably connected to the pivot end 188 of the second support leg 132, a first rod 484, and a second rod 560. The second rod 560 may be further connected to the shuttle 494. In some embodiments, the latch assembly 480 is spring-loaded to return to a retaining position 516. Here again, at least one pull wire or cable may be included in lieu of the first rod 484 and the second rod 560 and, in some instances, the lever plate 486. The shuttle 494 may be utilized as the pulling actuator in this example; however, any suitable pulling actuator may be included to allow the user to manually control the latch assembly 480.

[0086] FIGS. 14 and 15 illustrate an example of the carriage system 400, shown without the accessory 404, transitioning from the deployed configuration 416 (FIG. 14) to the collapsed configuration 540 (FIG. 15). The shuttle 494 or other pulling actuator may be pulled or moved, e.g., in the outward direction indicated by arrow 562 in FIG. 14. Actuation of the shuttle 494 may allow the first support arm 160 and the first support beam 420 to pivot relative to the first support leg 130 and allow the second support arm 162 and the second support beam 422 to pivot relative to the second support leg 132. Thereby, the tabletop assembly 406 may rotate or pivot relative to the first and second support legs 130, 132 in the direction indicated by the arrow 564 in FIG. 14. This may move the carriage system 400 to the first intermediate configuration 520 (FIG. 11). Before, during, or after moving the carriage system 400 to the first intermediate configuration 520 via actuation of the shuttle 494, the kickplate 474 may be actuated or pushed, e.g., via a user’s foot, in the direction indicated by arrow 566 to move the carriage system 400 to the second intermediate configuration 530 (FIG. 12). Actuating the kickplate 474 may allow the lower shelf assembly 408 to fold in the upward direction indicated by the arrow 568. Additionally, actuating the kickplate 474 may allow the third support leg 436 to pivot relative to the first support leg 130 and allow the fourth support leg 438 to pivot relative to the second support leg 132. The relative pivoting movement of the third and fourth support legs 436, 438 and the folding of the lower shelf assembly 408 may allow the front wheels 414 to move in the direction indicated by arrow 570 toward the rear wheels 412. When16HB: 4917-3871-6768.1Aty. Docket No.535634-266 the carriage system 400 is moved to the collapsed configuration 540 shown in FIG. 15, the at least one catch 542, e.g., at least one spring clip, may releasably engage at least one of the third and fourth support legs 436, 438.

[0087] FIG. 16 illustrates a carriage system 600 according to an embodiment. The carriage system 600 may include the carriage assembly 402 connected to an accessory 604. In the illustrated example of FIG. 1, the accessory 604 is a basket. It should be understood that the accessory 604 may be any of a multitude of accessories (e.g., tools, lighting sources, coolers, etc.). The carriage assembly 402 may include the tabletop assembly 406 connected to the lower shelf assembly 408 via the linkage assembly 410. The pair of rear wheels 412 and the pair of front wheels 414 preferably support the linkage assembly 410. In the illustrated example of FIG. 16, the carriage system 600 is in a deployed configuration 616. The accessory 604 is preferably removably connected to the tabletop 428 in the same manner as discussed above with respect to the accessory 404.

[0088] FIGS. 17 and 18 illustrate another example of a carriage system 700 that may transition between a deployed configuration 702 (FIG. 17) and a collapsed configuration 704 (FIG. 18). The carriage system 700, similar to the carriage systems 100, 300, 400, and 600, may include a carriage assembly 706 connected to an accessory 708 such as a grill, basket, tool, lighting source, cooler, or any other suitable accessory. The carriage assembly 706 may enable the carriage system 700 to transition between the deployed configuration 702 and the collapsed configuration 704. In the deployed configuration 702, the carriage assembly 706 may provide stable support for the accessory 708 for use by a user. In the collapsed configuration 704, the carriage assembly 706 may enable easy and comfortable transport of the accessory 708. In some embodiments, the carriage assembly 706 is supported by a plurality of wheel units 710 that provide mobility to the carriage system 700. The wheel units 710 may be selectively locked or otherwise rendered substantially immobile, e.g., via integrated brakes, when desired, such as when the carriage system 700 is in the deployed configuration 702.

[0089] The carriage assembly 706 may include a tabletop assembly 712 connected to a lower shelf assembly 714 via a linkage assembly 716. The linkage assembly 716 may include a first pair of support legs 718 and a second pair of support legs 720 that are pivotable relative to the first pair of support legs 718. The second pair of support legs 720 may extend between the lower shelf assembly 714 and middle portions of the first pair of support legs 718, and the second pair of support legs 720 may be pivotable at the ends proximate to the first pair of support legs 718. The first pair of support legs 718 may extend between the tabletop assembly 712 and the lower shelf assembly 714. The tabletop assembly 712 may be pivotable relative17HB: 4917-3871-6768.1Aty. Docket No.535634-266 to the first pair of support legs 718. A pair of support arms 722 may extend between the first pair of support legs 718 and the tabletop assembly 712. The tabletop assembly 712 may be pivotable relative to the pair of support arms 722. The pair of support arms 722 may be slidable along or relative to the first pair of support legs 718 toward and away from the tabletop assembly 712. The first pair of support legs 718, the second pair of support legs 720, and the pair of support arms 722 may cooperatively define a X-shape or scissor-shape profile of the linkage assembly 716 when the carriage system 700 is in the deployed configuration.

[0090] To transition the carriage system 700 from the deployed configuration 702 to the collapsed configuration 704, the second pair of support legs 720 and the pair of support arms 722 may move relative to the first pair of support legs 718. For example, the second pair of support legs 720 may pivot relative to and move toward the first pair of support legs 718 in the direction indicated by the arrows 724, 726 in FIG. 17. The lower shelf assembly 714 may also fold in the upward direction indicated by the arrow 728 to allow the movement of the second pair of support legs 720 toward the first pair of support legs 718. The pair of support arms 722 may slide along or relative to the first pair of support legs 718 in the direction indicated by the arrow 730. The tabletop assembly 712 may pivot relative to the first pair of support legs 718 in the direction indicated by the arrow 732 and relative to the pair of support arms 722 in the direction indicated by the arrow 734. The relative movement of the tabletop assembly 712, the lower shelf assembly 714, the second pair of support legs 720, and the pair of support arms 722 to the first pair of support legs 718 allows the carriage system 700 to be compactly folded as shown in FIG. 18 in the collapsed configuration 704 whereby the carriage system 700 can be towed or moved easily for transporting the accessory 708.

[0091] Referring to FIG. 19, the carriage system 700 may include a latch assembly 736 that selectively locks the carriage system 700 in the deployed configuration 702 (FIG. 17) or the collapsed configuration 704 (FIG. 18). The latch assembly 736 may include a pulling actuator 738, e.g., a squeezable handle or trigger, that is operably connected to a pull wire or cable 740. The pulling actuator 738 can be manipulated, e.g., pulled or squeezed, by a user, e.g., via their hand, which causes the pull cable 740 to unlatch or disengage the latch assembly 736. When the latch assembly 736 is disengaged, the carriage system 700 may be movable between the deployed configuration 702 and the collapsed configuration 704. The pulling actuator 738 is illustrated as being positioned on a handle of the tabletop assembly 712; however the pulling actuator 738 may be positioned at any suitable location.

[0092] A kickplate 742 may also be positioned proximate the lower shelf assembly 714 and may allow a user to exert a force, e.g., via their foot, to facilitate folding the lower shelf18HB: 4917-3871-6768.1Aty. Docket No.535634-266 assembly 714 and / or moving the second pair of support legs 720 to move the carriage system 700 to the collapsed configuration 704 (FIG. 18). In some embodiments, biasing elements 744, e.g., torsion springs, may exert an outward biasing force on the second pair of support legs 720 that can be overcome via the force exerted on the kickplate 742. Preferably, as shown in FIG. 19, the pulling actuator 738 is positioned proximate the tabletop assembly 712 and the kickplate is positioned proximate the lower shelf assembly 714 at suitable locations that are simultaneously accessible by the user. In this way, the user may manipulate the pulling actuator 738 and exert a force on the kickplate 742 concurrently, or nearly concurrently, to easily reconfigure the carriage system 700 from the deployed configuration 702 to the collapsed configuration 704, and / or vice versa.

[0093] Referring to FIG. 20, the pull cable 740 may be operably coupled to a first pivotable latch 746 positioned between one of the support arms 722 and one of the support legs 718. The first latch 746 may pivot to selectively engage and disengage a crossbar 748 extending between the pair of support arms 722. The crossbar 748 may extend slightly outward or beyond the pair of support arms 722 and may be received in slots 750 defined in inner surfaces of the first pair of support legs 718. FIG. 20 shows the slot 750 defined in one of the support legs 718. The slots 750 and the crossbar 748 may guide the sliding movement of the pair of support arms 722 relative to the first pair of support legs 718. The first latch 746 may engage the crossbar 748 between one of the support arms 722 and one of the support legs 718 to limit or prevent the sliding movement of the pair of support arms 722. Referring to FIG. 21, actuating the pulling actuator 738 (FIG. 19) may cause the pull cable 740 to pivot the first latch 746 such that the first latch 746 disengages the crossbar 748, thereby allowing the sliding movement of the pair of support arms 722. The first latch 746 may selectively engage the crossbar 748 as shown in FIG. 20 when the carriage system is in the deployed configuration 702 (FIG. 17) and may disengage the crossbar 748 as shown in FIG. 21 when the user desires to move the carriage system 700 to the collapsed configuration 704 (FIG. 18). When the carriage system 700 moves to the deployed configuration 702 from the collapsed configuration 704, the first latch 746 may re-engage the crossbar 748 to releasably lock the pair of support arms 722 relative to the first pair of support legs 718.

[0094] Still referring to FIGS. 20 and 21, the pull cable 740 may also be operably coupled to a second pivotable latch 752. The second latch 752 may be pivotably connected to the same one of the first pair of support legs 718 as the first latch 746. The second latch 752 may pivot to selectively engage and disengage a pin 754 on one of the support legs 720. As can be seen in FIGS. 20 and 21, actuating the pulling actuator 738 to cause pivoting movement19HB: 4917-3871-6768.1Aty. Docket No.535634-266 of the first latch 746 also causes pivoting movement of the second latch 752. In this way, actuation of both latches 746, 752 can advantageously be controlled via a single pulling actuator 738.

[0095] Referring to FIG. 22, the second latch 752 may engage the pin 754 on one of the support legs 720 when the carriage system 700 is in the collapsed configuration 704. Engagement between the second latch 752 and the pin 754 may facilitate limiting or preventing the second pair of support legs 720 from prematurely moving outward relative to the first pair of support legs 718 from the biasing force exerted via the biasing elements 744. In this way, engagement between the second latch 752 and the pin 754 may facilitate maintaining the carriage system 700 in the collapsed configuration 704 until the pulling actuator 738 (FIG. 19) is actuated. Referring to FIG. 23, when the user desires to move the carriage system 700 from the collapsed configuration 704 to the deployed configuration 702, the user may actuate the pulling actuator 738 which causes the second latch 752 to disengage the pin 754.

[0096] When the second latch 752 disengages the pin 754, the biasing force via the biasing elements 744 may then be released, causing the second pair of support legs 720 to pivot and move away from the first pair of support legs 718. As shown in FIGS. 22 and 23, the biasing elements 744, e.g., torsion springs, may be operably coupled between the first pair of support legs 718 and the second pair of support legs 720. In particular, the biasing elements 744 may be positioned at or proximate pivoting points 756 between the pairs of support legs 718, 720. In some embodiments, a crossbeam 758 may extend between the second pair of support legs 720 and working ends of the biasing elements 744 may exert a force on the crossbeam 758. The force exerted on the crossbeam 758 may cause the second pair of support legs 720 to pivot and move outward relative to the first pair of support legs 718.

[0097] Referring to FIGS. 24 and 25, in some embodiments, the carriage system 700 may include a dampener or shock absorber 760 operable to dampen or absorb shocks experienced by the carriage system 700 when transitioning between the deployed configuration 702 (FIG. 24) and the collapsed configuration (FIG. 25). The dampener 760 may be coupled between the tabletop assembly 712 and the linkage assembly 716. For example, the dampener 760 may be coupled between the tabletop assembly 712 and one of the first pair of support legs 718. In some embodiments, the dampener 760 may be coupled between the tabletop assembly 712 and the lower shelf assembly 714, and / or between the linkage assembly 716 and the lower shelf assembly 714. Preferably, at least one end of the dampener 760 is pivotable or swivelable, e.g., via a ball joint 762, to allow the dampener 760 to follow the movement of the carriage20HB: 4917-3871-6768.1Aty.
