A hinge for pivotally joining a first frame member and a second frame member of a frame of a stroller may include a first housing portion, a second housing portion, a release actuator and a locking member. The first housing portion may be operably coupled to the first frame member. The second housing portion may be operably coupled to the second frame member. The release actuator may be configured to operate to enable the hinge to shift between a locked state and an unlocked state. The locking member may be configured to move in an axial direction responsive to shifting between the locked state and the unlocked state. The external periphery of the locking member may include a first incline surface that engages both the first housing portion and the second housing portion in the locked state.

1. A stroller comprising: a seat for supporting a passenger;a frame configured to support the seat, the frame comprising at least a first frame member and a second frame member; anda hinge configured to pivotally engage the first and second frame members to each other,wherein the hinge comprises: a first housing portion operably coupled to the first frame member,a second housing portion operably coupled to the second frame member,a release actuator configured to operate to enable the hinge to shift between a locked state and an unlocked state, anda locking member configured to move in an axial direction responsive to shifting between the locked state and the unlocked state,wherein the locking member is formed in a substantially frustoconical shape, andwherein an external periphery of the locking member comprises a first incline surface that engages both the first housing portion and the second housing portion in the locked state. 2. The stroller of claim 1, wherein the first housing portion defines a substantially frustoconically shaped receiving space to receive the locking member, an internal periphery of the receiving space comprising a second incline surface configured to engage the first incline surface when the locking member is in the locked state. 3. The stroller of claim 2, wherein the first housing portion includes a locking insert forming an annulus, an outer periphery of the annulus being fixedly engaged with the first housing portion, and an inner periphery of the annulus forming the receiving space. 4. The stroller of claim 2, wherein the first housing portion and the locking member each include corresponding teeth and apertures configured to be in registration with each other, the first and second incline surfaces being formed on the corresponding teeth and apertures. 5. The stroller of claim 4, wherein the hinge further comprises a spring provided coaxially with the locking member to bias the locking member into the locked state, and wherein the sliding engagement of the ramp surfaces and ramps overcomes a force of the spring to transition the locking member into the unlocked state. 6. The stroller of claim 1, wherein the release actuator comprises a plurality of ramp surfaces configured to engage corresponding ramps of the locking member, the ramp surfaces and ramps providing sliding engagement of the release actuator to transition the locking member into the unlocked state. 7. The stroller of claim 6, wherein the sliding engagement of the ramp surfaces and ramps is initiated responsive to manual actuation of an operator coupled to the release actuator via a cable. 8. The stroller of claim 1, wherein the hinge further comprises a restraining assembly configured to hold the locking member in the locked state. 9. The stroller of claim 8, wherein the restraining assembly comprises a head portion configured to be disposed between a base of the locking member and a surface of the first housing portion or the second housing portion to inhibit axial motion of the locking member to retain the locking member in the locked state. 10. The stroller of claim 8, wherein the restraining assembly comprises restraining protrusions disposed at the release actuator and restraining apertures disposed at a base of the locking member, and wherein the restraining protrusions are configured to slide within corresponding ones of the restraining apertures when the locking member is in or transitioning to the unlocked state. 11. The stroller of claim 10, wherein the release actuator comprises orientation ramps positioned on an interior surface of the release actuator to engage orientation guide slots disposed on a hub of the locking member. 12. The stroller of claim 1, wherein the locking member has a first diameter at a base of the locking member and a second diameter at a top of the locking member, the first diameter being larger than the second diameter. 13. The stroller of claim 12, wherein the receiving space comprises a third diameter at a base of the receiving space and a fourth diameter at a top of the receiving space, the third diameter being larger than the fourth diameter, and wherein the fourth diameter is less than the first diameter and greater than the second diameter. 14. The stroller of claim 1, wherein a radial spring is provided to impart a rotational force on the release actuator to bias the release actuator to hold the locking member in the locked state. 15. A hinge for pivotally joining a first frame member and a second frame member of a frame of a stroller, the hinge comprising: a first housing portion operably coupled to the first frame member,a second housing portion operably coupled to the second frame member,a release actuator configured to operate to enable the hinge to shift between a locked state and an unlocked state, anda locking member configured to move in an axial direction responsive to shifting between the locked state and the unlocked state,wherein the locking member is formed in a substantially frustoconical shape, andwherein an external periphery of the locking member comprises a first incline surface that engages both the first housing portion and the second housing portion in the locked state. 16. The hinge of claim 15, wherein the first housing portion defines a substantially frustoconically shaped receiving space to receive the locking member, an internal periphery of the receiving space comprising a second incline surface configured to engage the first incline surface when the locking member is in the locked state. 17. The hinge of claim 16, wherein the first housing portion includes a locking insert forming an annulus, an outer periphery of the annulus being fixedly engaged with the first housing portion, and an inner periphery of the annulus forming the receiving space, and wherein the first housing portion and the locking member each include corresponding teeth and apertures configured to be in registration with each other, the first and second incline surfaces being formed on the corresponding teeth and apertures. 18. The hinge of claim 15, wherein the release actuator comprises a plurality of ramp surfaces configured to engage corresponding ramps of the locking member, the ramp surfaces and ramps providing sliding engagement of the release actuator to transition the locking member into the unlocked state.
