What is claimed is: 1. A shelter, comprising: a number of vertical support legs at spaced peripheral intervals beneath a canopy; a number of mounting members; a center mounting member extending upwardly from the vertical support legs; and truss sections extending from the mounting members and the center mounting member, wherein the truss sections include a number of pairs of arm members with terminal ends connected to one or more of the mounting members and the center mounting member, wherein the mounting members each have a mounting base with a number of bosses to limit the pivotal movement of the arm members and the arm members are pivotally connected to an outer side surface area of the bosses; and wherein a particular one of the number of bosses includes a limit stop member extending laterally and outwardly from an exterior of the particular boss, wherein the limit stop member is configured for wedging a particular arm member against movement with respect to the particular boss. 2. The shelter of claim 1, wherein the number of bosses include slot members. 3. The shelter of claim 1, wherein the number of bosses extend laterally outwardly from the mounting base. 4. The shelter of claim 1, wherein the limit stop member is juxtaposed to the particular boss to limit the pivotal movement of the particular arm member. 5. The shelter of claim 1, wherein the arm members include a collar at one end. 6. The shelter of claim 1, wherein the mounting members are pivotally connected to the arm members with a bolt and a pivot shaft inserted through aligned bores on the terminal ends of the arm members and the number of bosses. 7. The shelter of claim 6, wherein the pivot shaft is a fixed hollow pivot shaft and the bolt is a hex bolt. 8. A shelter assembly, comprising: telescoping vertical support legs at spaced peripheral intervals beneath a canopy; a telescoping center support member; and a number of truss sections each including a number of arm members, a first end of the arm members connected to a free mounting member, and a second end of the arm members connected to a mounting member on the vertical support legs or the center support member, wherein each of the mounting members, free mounting members, and the center support member have a number of bosses each including a first bore extending therethrough and a stabilizing member extending outwardly and laterally from the boss, wherein the first and second ends of the arm members each have a bore aligned with the first bore, are pivotally mounted in juxtaposition to one of the number of bosses, and have their path of pivotal movement limited by the stabilizing member; and wherein the first end of the arm members is pivotally mounted along an outer side surface area of one of the number of bosses. 9. The shelter assembly of claim 8, wherein the second end of the arm members is pivotally mounted on an outer side surface area of one of the number of bosses. 10. The shelter assembly of claim 8, wherein the number of bosses each include a hexagonal seat portion. 11. The shelter assembly of claim 8, wherein the stabilizing member includes an upper concave lip portion and a lower outwardly extending portion. 12. The shelter assembly of claim 11, wherein the upper concave portion has a curved side wall. 13. The shelter assembly of claim 8, wherein the mounting members include an adjustable locking member with a lever control including a release pin and a spring member mounted under compression between the lever control and a base mounting member and wherein the spring member is resiliently urging the lever control in a direction causing the release pin to engage mutually aligned bores on the telescoping vertical leg. 14. A device for locking telescoping members into place, comprising: a base mounting member adapted to be slidably mounted on the telescoping members an adjustable locking member having a lever control including a release pin and a spring member mounted under compression between the lever control and the base mounting member; and a protective sleeve member covering the lever control and the spring member, wherein the protective sleeve member and the lever control are pivotally connected to the base mounting member and are configured to prevent foreign objects from entering the spring member; wherein the spring member is resiliently urging the lever control in a direction causing the release pin to engage mutually aligned bores on the base mounting member and the telescoping members. 15. The device of claim 14, wherein the adjustable locking member is mounted on a lower end of the telescoping member. 16. The device of claim 14, wherein the spring member is mounted on an underside of the lever control. 17. The device of claim 14, wherein the protective sleeve member and the lever control are held in place with a pin running through a common pivot point of the protective sleeve member and the lever control. 18. The device of claim 14, wherein the lever control has a pressure pad. 19. The device of claim 14, wherein the spring member is mounted under compression between the lever control and the base mounting member such that additional compression of the spring member to a particular deflection by operation of the lever control causes the release pin to disengage the mutually aligned bores. 20. A device for locking telescoping members into place, comprising: a base mounting member adapted to be slidably mounted on the telescoping member an adjustable locking member having a lever control including a release pin and a spring member mounted under compression between the lever control and the base mounting member; and a protective sleeve member covering the lever control and the spring member; wherein the spring member is resiliently urging the lever control in a direction causing the release pin to engage mutually aligned bores on the base mounting member and the telescoping members; and wherein the protective sleeve member and the lever control are pivotally connected to the base mounting member and are held in place with a pin running through a common pivot point of the protective sleeve member and the lever control. 21. The device of claim 20, wherein the spring member is mounted under compression between the lever control and the base mounting member such that additional compression of the spring member to a particular deflection by operation of the lever control causes the release pin to disengage the mutually aligned bores.
