Description

Technical Field

[0001] This disclosure relates to chairs for children, and particularly, but not exclusively, to high chairs for children. Background Technology

[0002] Young children are often placed in chairs, especially high chairs, while eating or being fed. High chairs provide a comfortable seating position for children to eat or engage in other seated activities. High chairs are typically constructed so that a child sitting in a high chair is at a similar height to an adult when seated. This allows children sitting in high chairs to interact more easily with adults sitting at a table and increases the convenience for seated adults to feed the child.

[0003] Because of the height of the high chair seat, it is important that high chairs include appropriate support components (such as legs) to reduce the risk of the high chair tipping over when a child is sitting in it. Therefore, high chairs typically have a large footprint and can take up significant space in a room, such as around a table. Summary of the Invention

[0004] According to one aspect of this disclosure, a chair for children, such as a high chair, is provided, the chair comprising: a seat assembly; a front leg assembly pivotally coupled to the seat assembly; a rear leg assembly pivotally coupled to the seat assembly; a locking mechanism configured to selectively lock the front leg assembly and / or the rear leg assembly relative to the seat assembly to restrict pivoting of the front leg and / or the rear leg relative to the seat assembly; and an actuator operable to unlock the locking mechanism so that the assembled front leg and rear leg can pivot relative to the seat assembly.

[0005] The front and rear support leg assemblies may have proximal and distal ends, and their proximal ends may be connected to the seat assembly. The front and rear support leg assemblies may pivot relative to the seat assembly between a deployed configuration and a stored configuration, in which the distal ends of the front and rear support leg assemblies are spaced apart from each other, and in the stored configuration, the distal ends of the front and rear support leg assemblies are closer together than in the deployed configuration.

[0006] The actuator may include a foot pedal. The actuator may be mounted on the rear outrigger assembly.

[0007] The chair can be configured such that, while operating the actuator to unlock the locking mechanism, pushing the seat assembly of the chair, for example in the longitudinal direction of the chair (such as forward), causes the front leg assembly and the rear leg assembly to move toward the storage configuration.

[0008] The chair may further include a leg assembly link configured to connect to a front leg assembly and a rear leg assembly. The leg assembly link may be configured to allow the front and rear leg assemblies to move together between the unfolded configuration and the stored configuration.

[0009] The outrigger assembly link may include a rotary link element pivotally connected to the seat assembly. The outrigger assembly link may further include a front link element for connecting the front outrigger assembly to the rotary link element. The outrigger assembly link may further include a rear link element for connecting the rear outrigger assembly to the rotary link element. At least one of the front and rear link elements may be arcuate. The rotary link element may be connected to the seat assembly at a location deviating from a straight line extending from the locations where the front and rear link elements connect to the rotary link element.

[0010] The locking mechanism may include a front guide member coupled to the seat assembly, wherein the front guide member includes one or more front guide surfaces. The locking mechanism may further include a front support pin coupled to the front support leg assembly. The actuator may be operable to move the front support pin from a locked position to an unlocked position, in which the front support pin can engage the front guide surfaces to restrict pivoting of the front support leg assembly relative to the seat assembly, and in the unlocked position, the front support pin does not engage the front guide surfaces, thereby allowing the front support leg assembly to pivot relative to the seat assembly.

[0011] The front guide component may include a front deployment guide surface and a front storage guide surface. When the front outrigger assembly is in the deployed position, the front outrigger pin can engage with the front deployment guide surface. When the front outrigger assembly is in the storage position, the front outrigger pin can engage with the front storage guide surface.

[0012] The locking mechanism may include a front outrigger pin moving portion movably, for example, slidably, coupled to the front outrigger assembly. The front outrigger pin moving portion may be configured to engage the front outrigger pin as the front outrigger pin moving portion moves relative to the front outrigger assembly, thereby allowing the front outrigger pin to move between a locked position and an unlocked position. The actuator may be configured to move the front outrigger moving portion to move the front outrigger pin between the locked and unlocked positions.

[0013] The locking mechanism may include a rear guide member coupled to the seat assembly, wherein the rear guide member includes one or more rear guide surfaces. The locking mechanism may further include a rear support leg pin coupled to the rear support leg assembly. The actuator may be operable to move the rear support leg pin from a locked position to an unlocked position, in which the rear support leg pin can engage the rear guide surfaces to restrict pivoting of the rear support leg assembly relative to the seat assembly, and in the unlocked position, the rear support leg pin does not engage the rear guide surfaces, thereby allowing the rear support leg assembly to pivot relative to the seat assembly.

[0014] The rear guide component may include a rear deployment guide surface and a rear storage guide surface. When the rear support leg assembly is in the deployed position, the rear support leg pin can engage with the rear deployment guide surface. When the rear support leg assembly is in the storage position, the rear support leg pin can engage with the rear storage guide surface.

[0015] The locking mechanism includes a rear outrigger pin moving portion that is movably, for example, slidably connected to the rear outrigger assembly. The rear outrigger pin moving portion may be configured to engage the rear outrigger pin as the rear outrigger pin moving portion moves relative to the rear outrigger assembly, so that the rear outrigger pin can move between the locked position and the unlocked position.

[0016] The actuator may be configured to move the rear support leg travel portion to move the rear support leg pin between the locked position and the unlocked position. The chair may further include a cable extending from the actuator to the locking mechanism. Operating the actuator can pull the cable. The locking mechanism may be configured to move the rear support leg pin to the unlocked position when the cable is pulled by the actuator. For example, the cable may be coupled to the rear support leg pin travel portion.

[0017] The locking mechanism may include a pin link. The pin link may be configured to operably connect the front outrigger pin to the rear outrigger pin such that when the locking mechanism causes the rear outrigger pin to move to the unlocked position, the front outrigger pin moves to the unlocked position. The pin link may be configured to connect a movable portion of the front outrigger pin to a movable portion of the rear outrigger pin, such that the movable portions of the front and rear outrigger pins move together.

[0018] The locking mechanism may include a front guide member coupled to the seat assembly, wherein the front guide member includes one or more front guide surfaces. The locking mechanism may further include a front support pin coupled to the front support leg assembly. The front support pin may be configured to engage one of the front guide surfaces to restrict pivoting of the front support leg assembly relative to the seat assembly. The actuator may be operable to move the front support pin to prevent the pin from engaging the front guide surface, thereby allowing the front support leg assembly to pivot relative to the seat assembly.

[0019] The chair may include a locking assembly disposed on either lateral side of the chair, the locking assembly being used to lock the positions of the front support leg assembly and the rear support leg assembly on the two lateral sides of the chair.

[0032] refer to Figure 1 and Figure 2 The chair 10 (e.g., a high chair) arranged according to this disclosure includes a seat assembly 100, which includes a seat 110. The seat 110 includes a seat base 112 for a child to sit on, a seat back 114, and a first sidewall 116a and a second sidewall 116b located on respective lateral sides of the seat base 112.

[0033] The chair 10 further includes a front leg assembly 20 and a rear leg assembly 30. The front and rear leg assemblies are used to support the seat assembly 100 above a surface on which the chair 10 is placed (such as a floor). As shown, the front leg assembly 20 is connected to the seat assembly in a position that is further forward on the chair 10 in the longitudinal direction (perpendicular to the seat back) than the rear leg assembly 30. Furthermore, when the chair 10 is in an unfolded configuration, as... Figure 1 As shown, the front support leg assembly 20 can extend forward from the seat assembly 100, and the rear support leg assembly 30 can extend rearward from the seat assembly, for example, to provide stable support for the seat assembly 100 above the surface on which the chair 10 stands.

[0034] The chair 10 may further include a tray 40 configured to be attached to the seat assembly 100 to provide a table for a child sitting on the seat 110. For example, the tray 40 may be attached to a decorative part of the chair, such as a backrest extending across the child's knees when the child is seated. Additionally or alternatively, the tray 40 may be attached to a first sidewall 116a and / or a second sidewall 116b of the seat assembly. When the tray 40 is attached to the seat assembly 100 and the chair 10 is in an unfolded configuration (e.g., ...), Figure 1 As shown, the pallet surface 42 of the pallet can be substantially horizontal.

[0035] The front leg assembly 20 includes a first leg 22 and a second leg 24 disposed on each lateral side of the seat assembly. As described in more detail below, the first and second legs are coupled to the seat assembly at the proximal ends 22a and 24a of the first and second legs, respectively. The legs extend downward (optionally forward) away from the seat assembly 100, for example. The front leg assembly 20 further includes a footrest 26 extending between the distal ends 22b of the first leg and the distal ends 24b of the second leg (e.g., laterally between the distal ends 22b and 24b of the first and second legs). When the chair is placed on a surface such as a floor, the distal ends 22b and 24b of the first and second legs and / or the footrest 26 can contact the surface to support the seat assembly 100 above the surface.

[0036] The rear leg assembly 30 includes a first leg 32 and a second leg 34 disposed on each lateral side of the seat assembly. As described in more detail below, the first and second legs are coupled to the seat assembly at the proximal ends 32a and 34a of the first and second legs, respectively. The legs extend downward (optionally rearward) away from the seat assembly 100, for example. The rear leg assembly 30 further includes a footrest 36, which extends between the distal ends 32b of the first leg and the distal ends 34b of the second leg (e.g., laterally between the distal ends 22b of the first leg and the distal ends 24b of the second leg). When the chair is placed on a surface such as a floor, the distal ends 32b of the first leg and the distal ends 34b of the second leg and / or the footrest 36 can contact the surface to support the seat assembly 100 above the surface.

[0037] The seat assembly 100 further includes a first leg attachment assembly 120 and a second leg attachment assembly 130. As shown, the first leg attachment assembly 120 and the second leg attachment assembly 130 can be coupled to the seat, for example, to a corresponding lateral side of the seat 110. The front leg assembly 20 and the rear leg assembly 30 can be coupled to the first leg attachment assembly 120 and the second leg attachment assembly 130. Specifically, the first legs 22, 32 of the front leg assembly and the rear leg assembly can be coupled to the first leg attachment assembly 120, for example, at their proximal ends 22a, 32a, and the second legs 24, 34 of the front leg assembly and the rear leg assembly can be coupled to the second leg attachment assembly 130, for example, at their proximal ends 24a, 34a. Figure 3 and Figure 4 As shown, the first and second legs of the front and rear outrigger assemblies can be pivotally connected to the outrigger attachment assemblies 120 and 130 via outrigger pivot connector 140. The front and rear outrigger assemblies 20 and 30 may not have connectors at their distal ends, for example, at a location closer to the distal end of the outrigger assembly than the proximal end. Specifically, the front and rear outrigger assemblies may not be directly or indirectly connected to each other at their distal ends.

[0038] The leg assemblies 20 and 30 can be arranged relative to the seat assembly 100 in the unfolded configuration of the chair (e.g., Figure 1 (as shown) and storage configurations (such as) Figure 2 The chair can move between the front and rear leg assemblies (as shown), for example, it can pivot. In the unfolded configuration, the distal ends of the front and rear leg assemblies are spaced apart from each other, for example, in the longitudinal direction of the chair. In the storage configuration, the distal ends of the front and rear leg assemblies are closer together than in the unfolded position.

[0039] like Figure 1 As shown, in the unfolded configuration, the first leg 22 and the second leg 24 of the front leg assembly 20 can extend from the seat assembly 100 in directions having downward and forward components, and the first leg 32 and the second leg 34 of the rear leg assembly 30 can extend from the seat assembly 100 in directions having downward and rearward components. In other words, the front leg assembly 20 can extend from the seat assembly in a direction that is at an angle (e.g., a non-zero angle) relative to the direction in which the rear leg assembly 30 extends from the seat assembly. In the unfolded configuration, the chair 10 can have its maximum dimension in the longitudinal direction of the chair, for example, between the distal ends of the front leg assembly and the distal ends of the rear leg assembly. Therefore, in the unfolded configuration, the leg assemblies 20 and 30 can provide a stable base for the chair.

[0040] like Figure 2As shown, in the storage configuration, the first leg 22 and the second leg 24 of the front leg assembly 20 can extend from the seat assembly 100 in a substantially downward direction, and the first leg 32 and the second leg 34 of the rear leg assembly can also extend from the seat assembly 100 in a substantially downward direction. In other words, the front leg assembly 20 and the rear leg assembly 30 can extend from the seat assembly 100 in a substantially parallel direction. In the storage configuration, compared to the unfolded configuration, the longitudinal dimension of the chair (e.g., between the distal ends of the front leg assembly and the distal ends of the rear leg assembly) can be reduced, which can improve the storage convenience of the chair 100.

[0041] like Figure 2 As shown, in the storage configuration, tray 40 can be coupled to front support leg assembly 20 or rear support leg assembly 30. For example, the front or rear support leg assembly may include a crossbar 44 extending (e.g., laterally) between the first legs 22, 32 and the second legs 24, 34 of the front or rear support leg assembly, and tray 40 can be coupled to the crossbar. Seat assembly 100, front / rear support leg assembly 20, and / or tray 40 can be configured such that the same couplings provided on the tray can be interchangeably coupled to the seat (e.g., decorative portions of the seat (such as a web)) and the front / rear support leg assembly (e.g., coupled to the crossbar) as needed. Figure 2 As shown, when the pallet is connected to the front outrigger assembly or the rear outrigger assembly, the pallet surface 42 of the pallet can be substantially parallel to the first and second outriggers of the respective outrigger assembly.

[0042] refer to Figure 3 , Figure 4 and Figure 5 The chair 10 further includes a locking mechanism 300. The locking mechanism 300 is configured to selectively lock the front leg assembly 20 and the rear leg assembly 30, for example, in an unfolded configuration and / or a stored configuration, thereby preventing movement of the front and rear leg assemblies relative to the seat assembly 100 (e.g., pivoting about the leg pivot connector 140). The locking mechanism 300 can be configured to lock rotation of the front and rear leg assemblies at proximal ends of the front and rear leg assemblies. The locking mechanism 300 can be mounted on the seat assembly, for example, integrated into the first and / or second leg attachment assemblies.

[0043] Figure 3 , Figure 4 and Figure 5One of the outrigger attachment assemblies 120 and 130 and a locking assembly 300 disposed on one side (lateral side) of the seat assembly 100 are shown. It should be understood that similar locking assemblies may be disposed on the other side of the seat assembly for selectively locking the front and rear outrigger assemblies, for example, in an deployed configuration and / or a stored configuration, to the other side of the seat assembly. For example, the outrigger attachment assembly and locking mechanism disposed on the other side of the seat assembly could be… Figure 3 , Figure 4 and Figure 5 The image shows a mirror image of the leg attachment assembly and locking mechanism. Furthermore, it should be understood that, in the description of the locking mechanism, unless otherwise stated, references to components located on each lateral side of the chair refer to components located on the same side as the described locking mechanism.

[0044] The leg attachment assembly 120 may include a housing portion 122 and a cover portion 124, the cover portion 124 being engageable with the housing portion 122 to form an interior space 126. The housing portion 122 and / or the cover portion 124 may form a leg opening 128 on either side (e.g., either longitudinal side) of the leg attachment assembly for a leg of a leg assembly to be attached to a particular leg attachment assembly to pass through and enter the interior space 126. The leg assembly may be engaged with the leg attachment assembly within the interior space 126 of the leg attachment assembly. As shown, the leg opening 128 may be sized and shaped to allow the leg assemblies 20, 30 to move between an deployed configuration and a stored configuration. The housing portion 122 and / or the cover portion 124 and / or the distal ends 22a, 32a of the legs of the leg attachment assembly may be constructed (e.g., shaped) such that a portion of the interior space 126a is surrounded (e.g., substantially completely surrounded) by the housing portion 122, the cover portion 124, and / or the distal ends of the legs. As described below, components (e.g., moving parts) of the locking mechanism 300 of the chair 10 can be arranged within a portion of the interior space 126a to reduce the risk of items becoming trapped by components of the locking mechanism 300. In particular, enclosing the moving parts of the locking mechanism within a portion of the interior space can reduce the risk of fingers becoming trapped.

[0045] The locking mechanism 300 includes a front guide member 310 and a rear guide member 320. The front and rear guide members can be coupled (e.g., fixedly coupled) to the seat assembly 100, such as to the leg attachment assemblies 120, 130. For example, the front and rear guide members can be coupled to the housing portion 122. The front guide member 310 includes one or more guide surfaces 312, 314. In particular, the front guide member may include an unfolding guide surface 312 and a storage guide surface 314. Similarly, the rear guide member 320 includes one or more guide surfaces 322, 324. In particular, the rear guide member may include an unfolding guide surface 322 and a storage guide surface 324. As shown, the front and rear guide members 310 and 320 may include plates, and the guide surfaces may be surfaces extending around holes formed in the plates.

[0046] The locking mechanism 300 further includes a front outrigger pin 332 and a rear outrigger pin 334. The front and rear outrigger pins are respectively coupled (e.g., movably coupled) to the front outrigger assembly 20 and the rear outrigger assembly 30. Specifically, the front outrigger pin 332 is movable relative to the front outrigger assembly 20 between a locked position and an unlocked position. In the locked position, the front outrigger pin is capable of engaging guide surfaces 312, 314 of the front guide member 310; in the unlocked position, the front outrigger pin 332 does not engage the guide surfaces of the front guide member. The front outrigger pin can be positioned relative to the front pivot axis P. F The front outrigger assembly 20 moves between the locked and unlocked positions in a parallel direction about the front pivot axis P. F Relative to the movement of the seat assembly, the front pivot axis P F For example, it is defined by the outrigger pivot connector 140 that connects the front outrigger assembly to the seat assembly. When the front outrigger pin 332 is in the unlocked position, the front outrigger pin can retract into the hollow interior of the first front outrigger 22.

[0047] Similarly, the rear outrigger pin 334 is movable relative to the rear outrigger assembly 30 between a locked position and an unlocked position. In the locked position, the rear outrigger pin 334 engages with the guide surfaces 322, 324 of the rear guide member 320; in the unlocked position, the rear outrigger pin 334 does not engage with the guide surfaces of the rear guide member. The rear outrigger pin can be positioned relative to the rear pivot axis P. R The rear outrigger assembly 30 moves between the locked and unlocked positions in a parallel direction about the rear pivot axis P. R Relative to the movement of the seat assembly, the rear pivot axis P R For example, it is defined by the outrigger pivot connector 140 that connects the rear outrigger assembly to the seat assembly. When the rear outrigger pin 334 is in the unlocked position, the rear outrigger pin can retract into the hollow interior of the first rear outrigger 32.

[0048] When the guide surfaces 312, 314, 322, and 324 of the front and rear guide components are surfaces extending around holes formed in the guide components, the engagement of the front support pin 332 and the rear support pin 334 with the guide surfaces can correspond to the front support pin and the rear support pin received in the respective openings.

[0049] The front outrigger pin can be biased to move toward its locked position. Similarly, the rear outrigger pin can be biased to move toward its locked position. For example, the locking mechanism 300 may include a biasing element, such as a coil spring, configured to bias the front and rear outrigger pins toward their locked positions.

[0050] When the front outrigger pin 332 engages with one of the guide surfaces 312 and 314 of the front guide member, the engagement between the front outrigger pin and one of the guide surfaces serves to resist or prevent movement (e.g., pivoting) of the front outrigger assembly 20 relative to the seat assembly 100. Similarly, when the rear outrigger pin 334 engages with one of the guide surfaces 322 and 324 of the rear guide member, the engagement between the rear outrigger pin and one of the guide surfaces serves to resist or prevent movement (e.g., pivoting) of the rear outrigger assembly relative to the seat assembly.

[0051] Figure 4 The diagram shows an arrangement in which the front support leg assembly 20 is in the unfolded configuration of the chair 10 and the rear support leg assembly 30 is in the stored configuration of the chair. As shown, when the front support leg assembly 20 is in the unfolded configuration, the front support leg pin 332 is aligned with the unfolding guide surface 312 of the front guide plate 310. Therefore, when the front support leg pin 332 is in the locked position, the front support leg pin can engage with the unfolding guide surface 312. It should be understood that when the front support leg assembly is in the stored configuration, the front support leg pin 332 can be aligned with the stored guide surface 314 of the front guide plate. Therefore, when the front support leg assembly is in the stored configuration and the front support leg pin is in the locked position, the front support leg pin 332 can engage with the stored guide surface 314.

[0052] Similarly, as shown in the figure, when the rear outrigger assembly 30 is in the storage configuration, the rear outrigger pin 334 is aligned with the storage guide surface 324 of the rear guide plate 320. Therefore, when the rear outrigger pin is in the locked position, the rear outrigger pin 334 can engage with the storage guide surface 334. Similarly, it should be understood that when the rear outrigger assembly 30 is in the deployed configuration, the rear outrigger pin 334 can be aligned with the deployment guide surface 322 of the rear guide plate 320. Therefore, when the rear outrigger assembly 30 is in the deployed configuration, and the rear outrigger pin is in the locked position, the rear outrigger pin 334 can engage with the deployment guide surface 322.

[0053] refer to Figure 5The locking mechanism 300 may further include a front outrigger pin moving portion 342 and a rear outrigger pin moving portion 344. The front outrigger pin moving portion 342 may be movably (e.g., slidably) coupled to the front outrigger assembly 20, for example, coupled to the first outrigger 22. In this way, the front outrigger pin moving portion may be movable (e.g., slidable) relative to the front outrigger assembly 20. Specifically, the front outrigger pin moving portion 342 may be positioned relative to the front pivot axis P. F The movement occurs in a vertical direction. Furthermore, the front outrigger pin moving portion 342 can move in a direction perpendicular to the direction in which the front outrigger pin 332 moves between the locked and unlocked positions. For example, the front outrigger pin moving portion 342 can slide in a direction along the first outrigger 22, such as between the proximal end 22a and the distal end 22b of the first outrigger. The front outrigger pin moving portion 342 can be configured to engage the front outrigger pin 332 to, for example, cause the front outrigger pin to move between the locked and unlocked positions as the moving portion moves. For example, the front outrigger moving portion 342 may include a beveled surface, and the front outrigger pin may include a complementary beveled surface. The beveled surface and the complementary beveled surface can be configured to engage each other to cause the front outrigger pin to move between the locked and unlocked positions as the moving portion 342 moves.

[0054] In the illustrated arrangement, the locking mechanism 300 is configured such that when the current outrigger pin moving portion 342 moves toward the proximal end of the front outrigger assembly, the front outrigger pin moving portion engages the front outrigger pin 332 to move the front outrigger pin toward the unlocked configuration. The locking mechanism 300 can also be configured such that when the current outrigger pin moving portion 342 moves toward the distal end of the front outrigger assembly, the front outrigger pin moving portion engages the front outrigger pin 332 to move the front outrigger pin toward the locked position. Alternatively, the front outrigger pin 332 can be moved toward the locked position by means of a biasing member (such as a coil spring) that biases the front outrigger pin toward the locked position. As shown, the locking mechanism 300 may include a biasing element 346 (such as a coil spring) configured to move the front outrigger pin moving portion 342 toward the distal end of the front outrigger assembly, for example, toward the position where the front outrigger pin has moved to the locked position.

[0055] In other arrangements, the locking mechanism 300 may be configured such that when the current outrigger pin moving portion 342 moves toward the distal end of the front outrigger assembly, the front outrigger pin moving portion engages the front outrigger pin to move the front outrigger pin toward the unlocked configuration, and when the current outrigger pin moving portion 342 moves toward the proximal end of the front outrigger assembly, the front outrigger pin moves toward the locked configuration.

[0056] The rear outrigger pin moving portion 344 can be movably (e.g., slidably) coupled to the rear outrigger assembly 30 (e.g., coupled to the first outrigger 32). In this way, the rear outrigger pin moving portion 344 can be movable, for example, slidably relative to the rear outrigger assembly 30. The rear outrigger pin moving portion 344 can be positioned relative to the rear pivot axis P. R The rear outrigger pin moving portion 344 can move in a direction perpendicular to the direction in which the rear outrigger pin 334 moves between the locked and unlocked positions. For example, the rear outrigger pin moving portion can slide along the first leg 32 of the rear outrigger assembly (e.g., in a direction extending between the proximal and distal ends of the rear outrigger assembly). The rear outrigger pin moving portion 344 can be configured to engage the rear outrigger pin 334 so as to move the rear outrigger pin between the locked and unlocked positions, for example, when the front outrigger pin moving portion 344 moves. For example, the rear outrigger moving portion 344 may include a beveled surface, and the rear outrigger pin 334 may include a complementary beveled surface. The beveled surface and the complementary beveled surface can be configured to engage each other to cause the rear outrigger pin to move between the locked and unlocked configurations when the rear outrigger pin moving portion moves.

[0057] In the illustrated arrangement, the locking mechanism 300 is configured such that when the rear outrigger pin moving portion 344 moves toward the distal end of the rear outrigger assembly, the rear outrigger pin moving portion engages the rear outrigger pin 334 to move the rear outrigger pin toward the unlocked position. The locking mechanism 300 can also be configured such that when the rear outrigger pin moving portion 344 moves toward the proximal end of the rear outrigger assembly, the rear outrigger pin moving portion engages the rear outrigger pin 334 to move the rear outrigger pin toward the locked position. Alternatively, the rear outrigger pin 334 can be moved toward the locked position by means of a biasing member (such as a coil spring) that biases the rear outrigger pin toward the locked position. As shown, the locking mechanism 300 may include a biasing element 348 (such as a coil spring) configured to move the rear outrigger pin moving portion 344 toward the proximal end of the rear outrigger assembly, for example, toward the position where the rear outrigger pin has moved to the locked position.

[0058] In other arrangements, the locking mechanism 300 may be configured such that when the rear outrigger pin moving portion 344 moves toward the proximal end of the rear outrigger assembly, the rear outrigger pin moving portion engages the rear outrigger pin to move the rear outrigger pin toward the unlocked position, and when the rear outrigger pin moving portion 342 moves toward the distal end of the rear outrigger assembly, the rear outrigger pin moves toward the locking configuration.

[0059] refer to Figure 6 , Figure 7 and Figure 8The chair 10 further includes an actuator 700 operable to unlock the locking mechanism 300, thereby enabling the front leg assembly 20 and the rear leg assembly 30 to move (e.g., pivot) relative to the seat assembly 100, for example, between an unfolded configuration and a stored configuration.

[0060] The actuator 700 can be a foot-operated actuator, such as a foot pedal. In the illustrated arrangement, the foot pedal is located on the footrest 36 of the rear support leg assembly. However, in other arrangements, the foot pedal may be located on the footrest 26 of the front support leg assembly. Alternatively, the actuator 700 can be any other type of actuator, such as a hand-operated button, slider, or lever. Furthermore, in other arrangements, the actuator 700 may be located in any other position on the chair 10, such as on the seat assembly 100, for example, on one or both of the support leg attachment assemblies 120 and 130.

[0061] As shown, the chair 10 may further include a cable 710 extending from the actuator 700 to the locking mechanism 300. The cable may extend between the actuator 700 and the locking mechanism 300 disposed in the leg attachment assembly 120, passing through the hollow interior of the first leg 32 of the rear leg assembly. The actuator 700 may be configured to pull the cable 710 when the actuator is actuated.

[0062] Briefly return to Figure 5 The locking mechanism is configured such that when the actuator 700 pulls the cable 710, it causes the rear outrigger pin 334 to move to the unlocked position. Specifically, the cable 710 can be coupled to the rear outrigger pin moving portion 344, and when the actuator 700 pulls the cable 710, the rear outrigger pin moving portion 344 can move (e.g., slide) toward the distal end of the rear outrigger assembly, thereby moving the rear outrigger pin 342 toward the unlocked position, as described above.

[0063] In some arrangements, cable 710 or another cable may be connected to the front outrigger pin moving portion 342, for example as an addition or alternative to cable connection to the rear outrigger pin moving portion 344. In such an arrangement, locking mechanism 300 may be configured such that actuator 700 of traction cable 710 (and optionally another cable) moves the front outrigger pin moving portion 342, thereby moving the front outrigger pin 332 to the unlocked position.

[0064] The locking mechanism 300 may further include a pin link 500. The pin link 500 may be configured to operably connect the front outrigger pins 332 and 334 to the rear outrigger pin, such that when the rear outrigger pin moves to the unlocked position, the front outrigger pin also moves to the unlocked position. In other arrangements, such as where cable 710 or other cables are connected to the front outrigger pin moving portion 342 as an alternative to connecting cables to the rear outrigger pin moving portion 344, the front outrigger pin 332 may be operably connected to the rear outrigger pin 334, such that when the front outrigger pin moves to the unlocked position, the rear outrigger pin also moves to the unlocked position.

[0065] As shown in the figure, the pin linkage 500 may include a cable 510. The first end 510a of the cable can be connected to the rear outrigger pin moving part 344, and the second end 510b of the cable can be connected to the front outrigger pin moving part 342. When one of the front and rear outrigger pin moving parts moves due to the action of the actuator 700 and the cable 710, the cable 510 can pull the other of the front and rear outrigger pin moving parts, causing the other of the front and rear outrigger pin moving parts to move simultaneously.

[0066] Return to reference Figure 7 and Figure 8 The actuator 700 includes a housing portion 702 forming an internal space 704 of the actuator 700 and a cover portion 706 for closing the internal space. The actuator 700 further includes a slider 708 disposed within the internal space 704. The slider 708 may be movably (e.g., slidably) coupled to the housing portion 702. A cable 710 (e.g., a first end 710a of a cable) is coupled to the slider 708. The cover portion 706 includes a wedge 706a extending into the internal space 704. The cover portion 706 may be elastically deformable and may be configured such that deforming the cover portion (e.g., by pressing the cover portion) causes the wedge 706a to engage the slider 708. The wedge may include a ramp 706b, and the slider may include a complementary ramp 708a. The actuator can be configured such that when the cover portion deforms, the wedge 706a (e.g., the ramp 706b) engages the complementary ramp 708a of the slider, and the engagement between the wedge and the ramp causes the slider to move (e.g., slide) and pull the cable 710.

[0067] When chair 10 includes a locking assembly 300 on either lateral side of the chair, the chair may include another cable 720 extending from actuator 700 to a locking mechanism disposed on the other lateral side of the chair (in... Figure 6(As shown in the diagram). For example, another cable 720 may extend between the actuator 700 and the locking mechanism 300 through the hollow interior of the second leg 34 of the rear support leg assembly 30. In such an arrangement, the actuator 700 may include another slider 709 disposed within the actuator's internal space 704 and movably (e.g., slidably) coupled to the housing portion 702. Another cable 720 (e.g., a first end 720a of another cable) may be coupled to the other slider 709. The other slider 709 may include a complementary ramp 709a. The actuator 700 may be configured such that deformation of the cover portion 704 causes a wedge 704a (e.g., another ramp 706c of wedge 706a) to engage the other slider (e.g., the complementary ramp 709a of the other slider). Engagement between the wedge and the complementary ramp 709a of the other slider may cause the slider to move (e.g., slide) and pull the other cable 720. As described above, another cable (e.g., the second end of another cable) can be connected to the locking mechanism 300 on the other side of the chair in the same way that cable 710 is connected to the locking mechanism 300.

[0068] like Figure 7 and Figure 8 As shown, inclined surfaces 706b and 7076c can be formed on opposite lateral sides of the wedge, and slider 708 and another slider 709 can be driven to move away from wedge 706a in opposite lateral directions. Figure 7 and Figure 8 In this arrangement, one cable and another cable cross each other within the housing 702 to connect to a slider or another slider disposed on opposite sides of the housing. When slider 708 and another slider 709 are driven to move in opposite lateral directions, the two cables 710, 720 are thus pulled in opposite lateral directions to actuate locking mechanism 300, which is disposed in leg attachment assemblies 120, 130 on opposite lateral sides of the chair 10.

[0069] Due to the elastically deformable nature of the cover portion 706, releasing the cover portion causes the wedge 706a to move away from the slider 708 and the other slider 709. The sliders 706 and 709 can be biased to return to their initial positions, for example, before being driven to move by the wedge block. Furthermore, due to the biasing elements 346 and 348 provided in the locking mechanism 300, the locking mechanism can return to a locked configuration when the actuator is released. For example, the front support pin 332 and the rear support pin 334 can return to the locked position.

[0070] In other arrangements, the cover portion 706 may not be elastically deformable, but may include a button movable relative to the housing portion 702. The button may include a wedge 706a and may be movable relative to the housing portion to engage a slider 708 and another slider 709. In such an arrangement, the actuator 700 may include a biasing element (such as a coil spring) configured to bias the button toward a portion in which the wedge does not cause the slider and the other slider to correspondingly pull a cable and another cable.

[0071] return Figure 5 The chair 10 may further include a leg assembly link 550. The leg assembly link is configured to connect the front leg assembly 20 and the rear leg assembly 30 together, and cause the front and rear leg assemblies to move together between the chair's unfolded and stored configurations. In other words, the leg assembly link 550 is configured such that when one of the front leg assembly 20 and the rear leg assembly 30 moves from the unfolded configuration to the stored configuration, the leg assembly link causes the other of the front and rear leg assemblies to move from the unfolded configuration to the stored configuration. Similarly, when one of the front leg assembly 20 and the rear leg assembly 30 moves from the stored configuration to the unfolded configuration, the leg assembly link 550 causes the other of the front and rear leg assemblies to move from the stored configuration to the unfolded configuration.

[0072] As shown, the outrigger assembly link 550 may include a rotating link element 552 pivotally connected to the seat assembly 100 (e.g., connected to the outrigger attachment assembly 120). The rotating link element 552 may be configured about a pivot axis P. L The pivot axis P rotates relative to the seat assembly. L It can rotate parallel to the front pivot axis P of the front outrigger assembly and the rear outrigger assembly. F and / or rear pivot axis P R The outrigger assembly link 550 may further include a front link element 554. A first end 554a of the front link element may be coupled (e.g., pivotally coupled) to the front outrigger assembly 20, for example, to the proximal end of the first outrigger 22, and a second end 554b of the front link element may be coupled to a swivel link element. As shown, the front link element 554 may be arc-shaped. The outrigger assembly link 550 may further include a rear link element 556. A first end 556a of the rear link element may be coupled (e.g., pivotally coupled) to the rear outrigger assembly 30, for example, to the proximal end of the first outrigger 32, and a second end 556b of the rear link element may be coupled to a swivel link element. As shown, the rear link element may be straight.

[0073] The rotating link element 552 can be connected to the seat assembly 100 at a position that deviates from a straight line that extends from the position where the second end 554b of the front link element connects to the rotating link element and the position where the second end 556b of the rear link element connects to the rotating link element.

[0074] As shown in the figure, the front link element 554 can be connected to the front outrigger assembly 20 at a location on the front outrigger assembly, at a location on the front pivot axis P. F On the side opposite the distal end of the front outrigger assembly. Similarly, the rear link element 556 can be connected to the rear outrigger assembly 30 at a location on the rear pivot axis P. R The side opposite to the distal end of the rear support leg assembly.

[0075] Referring to Figure 9, the process of reconfiguring chair 10 from an unfolded configuration to a storage configuration will now be described. For example... Figure 9a and Figure 9b As shown, the chair 10 can initially tilt backward, causing the front support leg assembly (e.g., the distal end of the front support leg assembly) to be lifted off the ground. The seat assembly 100 can then be pushed forward while the actuator 700 is actuated, for example, to unlock the locking mechanism 300. Figure 9b , Figure 9c and Figure 9d As shown, pushing the seat assembly forward while the actuator is actuated causes the front outrigger assembly 20 and the rear outrigger assembly 30 to move together from the deployed configuration to the storage configuration. The actuator 700 can then be released to lock the front and rear outrigger assemblies in the storage configuration via the locking mechanism 300.

[0076] Referring to Figure 10, the process of reconfiguring the chair 10 from a storage configuration to an unfolded configuration will now be described. Figure 10a and Figure 10b As shown, the seat assembly 100 can initially be pulled backward while the actuator 700 is actuated, for example to unlock the locking mechanism 300. Figure 10b and Figure 10c As shown, the seat assembly 100 can be pushed forward. Pulling the seat assembly backward and / or pushing it forward while the actuator 700 is actuated can cause the front outrigger assembly 20 and the rear outrigger assembly 30 to move together from a storage configuration to an deployed configuration. Figure 10c and Figure 10d As shown, the chair 10 can then be tilted forward to an upright position and the actuator 700 released. The front and rear support leg assemblies can then be locked in the unfolded configuration via the locking mechanism 300.

[0077] Using the process shown in Figures 9 and 10, the chair can be reconfigured between the unfolded and stored configurations using only one hand.
