In a shelter according to claim 1 wherein said at least one boss includes slot members. 3. In a shelter according to claim 1 wherein said at least one boss extends laterally outwardly from said mounting members. 4. In a shelter according to claim 1 wherein said limit stop member interlocks with said arm member. 5. In a shelter according to claim 1 wherein said arm member includes a collar at one end. 6. In a shelter according to claim 1 wherein said pivotally connecting means includes the bolt member and the hollow shaft member inserted through aligned bores on said terminal ends of said arm members and said boss. 7. In a shelter according to claim 1 wherein said pivotally connecting means includes the hollow shaft member being a fixed hollow pivot shaft, and the bolt member being a hex bolt. 8. A device for locking telescoping members into place comprising: an adjustable locking member defined by a right angle lever control including a release pin and a spring member mounted under compression between said right angle lever control and a base mounting member, wherein said spring member is mounted at a right angle to said release pin, said spring member resiliently urging said right angle lever control in a direction causing said release pin to engage mutually aligned bores on said telescoping members, and wherein said spring member is mounted on an underside of said right angle lever control. 9. A device according to claim 8 wherein each of said telescoping members has a lower end, and wherein the adjustable locking member is adapted to be mounted on a respective lower end of said telescoping members. 10. A device according to claim 8 wherein said right angle lever control includes a protective sleeve member. 11. In a shelter assembly having vertical support members, a center support structure and arm members interconnecting said vertical support members and said center support structure, the improvement comprising: an adjustable locking member for adjusting the angle of extension between said arm members, said vertical support members and said center support structure; and said adjustable locking member defined by a base member, a right angle lever member including a push member located at a right angle to a retention pin, a spring member mounted below a pin member on said push member resiliently urging said pin member in a direction causing said retention pin to engage with mutually aligned bores on said vertical support members. 12. In a shelter assembly according to claim 11 wherein said right angle lever member includes opposing side panels. 13. In a shelter assembly according to claim 12 wherein said base member includes corresponding, opposing side panels with said opposing side panels of said right angle lever member. 14. In a shelter assembly according to claim 11 wherein said right angle lever member includes a pressure pad. 15. In a shelter having a canopy being surmounted on a collapsible frame, said frame having support members including vertical support legs, a center support extending upwardly into engagement with an undersurface of said canopy and truss members, the improvement comprising: means for positioning said frame in an upper locked position; said vertical support legs including upper and lower slidable sleeve members having mutually aligned bores, an upper terminal end of said upper sleeve member engaging said undersurface of said canopy; a base mounting member mounted on said vertical support leg, said base mounting member having a bore, and said position locking means defined by a spring member mounted under compression between a right angle pin lever member and said base mounting member, wherein said spring member is mounted at a right angle to said pin lever member, said spring member resiliently urging said pin lever member in a direction causing a retention pin mounted on an opposite end of said pin lever member to engage with said aligned bores on said sleeve members and said bore on said base mounting member, and wherein said retention pin is mounted at a right angle to said spring member. 16. In a shelter according to claim 15 wherein said position locking means is mounted near said upper terminal end of said upper sleeve member. 17. In a shelter according to claim 15 wherein said upper terminal end of said upper sleeve member includes a lock stop. 18. In a shelter a canopy being surmounted on a frame, said frame having vertical support legs, a center support extending outwardly into engagement with an undersurface of said canopy and truss sections having arm members extending from said vertical support legs and said center support, the improvement comprising: means mounted for adjusting the height of said vertical support legs; said vertical support legs including upper and lower slidable sleeve members having mutually aligned bores; and a base mounting member mounted on said vertical support leg, said base mounting member having a bore, and said adjusting means defined by a right angle release button having a spring member mounted under compression between said right angle release button and said base mounting member, said spring member resiliently urging said right angle release button in a direction causing a retention pin mounted on said release button to engage with said mutually aligned bores on said sleeve members and said bore on said base mounting member, and wherein said retention pin is mounted at a right angle to said spring. 19. In a shelter having a canopy and a collapsible frame including vertical support legs at spaced peripheral intervals beneath said canopy and a telescoping center support member and truss sections extending from said vertical support legs and said center support including arm members having terminal ends, the improvement comprising: slidable mounting members located on an upper end of said vertical support legs; said mounting members each having at least two bosses with a bore therethrough, said arm members including an aligned bore and pivotally mounted in juxtaposition to said bosses; position locking members included on said mounting members for increasing the angle of extension between said vertical support legs and said arm members; said vertical support legs having mutually aligned bores; and said position locking members defined by a spring member mounted under compression between a right angle pin lever member and a base mounting member, said spring member resiliently urging said pin lever member in a direction causing a retention pin mounted on an opposite end of said pin lever member to engage with said aligned bores, wherein said retention pin is mounted at a right angle to said spring member, and wherein said vertical support legs include a lock stop secured to an upper terminal end of said vertical support leg. 20. In a shelter according to claim 19 wherein said bosses include a stabilizer member extending laterally outwardly from an outer side surface of said bosses. 21.
