CLAIMS

1. A passageway comprising a plurality of sections, the sections comprising at least one section that is extendable and retractable, the at least one section including: a frame structure having a pair of upright members;

a pair of slide track assemblies disposed proximately to the respective upright members, each of the slide track assemblies including a slide track and a slide block, the slide track having a cavity and a channel, the slide block configured to ascend, descend, and rotate within the cavity, the slide block including a guide block that extends from the slide block at least partially through the channel;

a scissor bar assembly secured to the pair of upright members and to the pair of slide track assemblies such that the pair of upright members is enabled to extend and retract with respect to each other along at least one arcuate path, wherein the guide block limits rotation of the slide block within the slide track to rotation of the guide block within the channel.

2. The passageway of claim 1, wherein the slide track is defined by a back wall, perpendicular sidewalls, and angled sidewalls that extend from the perpendicular sidewalls, wherein the angled sidewalls define the channel.

3. The passageway of claim 1, wherein the slide block has a generally round cross-section.

4. The passageway of claim 1, wherein the slide block includes an alignment guide block, the alignment guide block including an arm and the guide block that is secured to the arm, the arm being secured within the channel of the slide block.

5. The passageway of claim 1, wherein the scissor bar assembly includes a scissor bar, the scissor bar including a first connector and a second connector.

6. The passageway of claim 5, wherein the first connector is pivotably secured within the channel of the slide block.

7. The passageway of claim 5, wherein the second connector is pivotably secured to an upright member.

8. The passageway of claim 1, wherein the pair of upright members comprises a pair of reciprocally mating members.

9. The passageway of claim 8, wherein a first mating member comprises a back, flared sides, and an arcuate receiving recess, and a second mating member comprises a back, flared sides, and an arcuate protrusion, wherein the arcuate protrusion is enabled to align with the arcuate receiving recess.

10. The passageway of claim 9, wherein the arcuate protrusion includes a band that extends at least partially along the arcuate protrusion, the band configured to interface with the arcuate receiving recess.

11. The passageway of claim 8, further comprising a pair of wheel assemblies secured to the mating members.

12. The passageway of claim 1, further comprising an arch member secured to the upright members, the arch member including a plurality of curved sections and a plurality of corresponding notched sections, the curved sections extending along a top portion of the arch member and the notched sections extending along a bottom portion of the arch member, wherein the notched sections are welded to provide stiffness to the arch member and mitigate splay of the upright members.
