Claims
- 1. A height adjustable support leg comprising:a leg member; and a glide device comprising a housing having a cavity and an opening defining a mouth of said cavity, said housing having a bottom surface adapted to engage a floor; a shaft threadably engaging said leg member, said shaft rotatably mounted in said housing, and wherein said housing is not rotatably movable relative to said leg member about a horizontal axis; and an actuator disposed in said cavity and mounted to a bottom end of said shaft, wherein said shaft and said actuator have concentric axes of rotation, and wherein a portion of said actuator is exposed in said mouth of said cavity.
- 2. The support leg of claim 1 wherein said actuator comprises a disk member.
- 3. The support leg of claim 2 wherein said disk member comprises a plurality of apertures positioned about a perimeter of said disk member, wherein said apertures are shaped to receive a tool that can be manipulated by a user to rotate the disk.
- 4. The support leg of claim 1 wherein said mouth of said cavity faces forward.
- 5. The support leg of claim 1 wherein said mouth opens to a side of said housing.
- 6. A height adjustable glide device for supporting a leg member on a floor, said glide device comprising:a housing having a cavity and an opening defining a mouth of said cavity, said housing having a bottom surface adapted to engage said floor, and wherein said housing further comprises a base portion and a stem portion extending upwardly from said base portion; a shaft adapted to threadably engage said leg, wherein said shaft is disposed in said stem portion and is rotatably mounted in said housing; and an actuator disposed in said cavity and mounted to a bottom end of said shaft, wherein said shaft and said actuator have concentric axes of rotation, and wherein a portion of said actuator is exposed in said mouth of said cavity.
- 7. The glide device of claim 6 wherein said shaft further comprises a shoulder engaging a top of said stem when said shaft is disposed in said stem.
- 8. The glide device of claim 7 wherein a top portion of said shaft located above said shoulder is adapted to threadably engage said leg.
- 9. A height adjustable glide device for supporting a leg on a floor, said glide device comprising:a housing comprising: a base portion having a cavity and an opening defining a mouth of said cavity, said base portion having a bottom surface adapted to engage said floor; and a stem portion extending upwardly from said base portion; an actuator disposed in said cavity and rotatably mounted to said housing, wherein a portion of said actuator is exposed in said mouth of said cavity, a shaft disposed in said stem portion and adapted to threadably engage said leg, said shaft having a bottom end mounted to said actuator and a shoulder engaging a top of said stem portion, said shaft and said actuator having concentric axes of rotation.
- 10. The glide device of claim 9 wherein said actuator comprises a disc member, wherein an edge portion of said disc protrudes from said mouth of said cavity for access by a user.
- 11. A method for adjusting the height of a support leg supported on a floor comprising:providing a support leg; providing a glide device comprising a housing having a cavity and an opening defining a mouth of said cavity, said housing having a bottom surface adapted to engage said floor, a shaft threadably engaging said support leg, wherein said shaft is rotatably mounted in said housing, and an actuator disposed in said cavity and mounted to a bottom end of said shaft, wherein said shaft and said actuator have concentric axes of rotation, and wherein a portion of said actuator is exposed in said mouth of said cavity; moving said portion of said actuator exposed in said mouth of said cavity; rotating said actuator about said axis of rotation in response to said moving said portion of said actuator; and rotating said shaft about said axis of rotation in response to said rotating of said actuator and threadably engaging said support leg with said shaft, and thereby moving said support leg in a generally vertical direction without rotating said support leg relative to said housing about a horizontal axis.
- 12. The method of claim 11 wherein said housing further comprises a base portion and a stem portion extending upwardly from said base portion, and wherein said shaft is disposed in said stem portion.
- 13. The method of claim 12 wherein said shaft further comprises a shoulder engaging a top of said stem.
- 14. The method of claim 13 wherein said shaft comprises a top portion located above said shoulder, wherein said top portion threadably engages said support leg.
- 15. The method of claim 11 wherein said actuator comprises a disk member.
- 16. The method of claim 15 wherein said disk member comprises a plurality of apertures positioned about a perimeter of said disk member, and wherein said moving said portion of said actuator comprises inserting a tool in at least one of said apertures and moving said tool.
- 17. The method of claim 11 wherein said mouth of said cavity faces forward.
- 18. The method of claim 11 wherein said mouth of said cavity opens to a side of said housing.
