Abstract

A support fixture for musical instruments, and more particularly, an improved support mechanism is provided incorporating a spin-lock type mechanism which permits quick and easy assembly while providing a sturdy and durable arrangement. The assembly mechanism of the invention is particularly suited for musical instruments stands to be used by small children.

Claims

1. A support for a musical instrument comprising:

a base member for placement on a support surface, said base member comprising a support rod defining a longitudinal axis and a key member disposed proximate one end of said support rod;

an attachment plate adapted to be affixed to an instrument, said attachment comprising an aperture adapted to receive said key member; and

locking means for securing said attachment plate to said base member at a locked position, wherein said base member is rotated relative to said attachment plate a predetermined angle from an unlocked position to said locked position.

2. The support according to claim 1, wherein said key member being adapted to pass into said aperture.

3. The support according to claim 2, wherein said attachment plate defines first and second opposed abutment surfaces.

4. The support according to claim 3, wherein said base member further comprises a tightening member.

5. The support according to claim 4, wherein said key member abuts said first abutment surface and said tightening member abuts said second abutment surface at said locked position.

6. The support according to claim 4, wherein said tightening member is threading disposed on said support rod to adjust a tightening force between said base member and said attachment plate.

7. The support according to claim 3, wherein said first abutment surface comprises at least one tang projecting therefrom.

8. The support according to claim 7, wherein said key member comprises at least one wing member adapted to abut said at least one tang at said locked position.

9. The support according to claim 1, wherein said attachment plate remains at a first position along said longitudinal axis during said relative rotation.

10. The support according to claim 1, wherein said key member is formed to congruously engage said aperture, said at least one wing member being adapted to pass through said aperture.

11. A support for a musical instrument comprising:

a base member for placement on a support surface, said base member comprising a support rod defining a longitudinal direction and a key member disposed proximate one end of said support rod, said key member having a plurality of projections extending radially from said rod;

an attachment plate adapted to be affixed to an instrument, said attachment comprising an aperture adapted to receive said key member; and

locking means for securing said attachment plate to said base member at a locked position, wherein said base member is adapted for angular rotation relative to said attachment plate while maintaining a fixed relative position in said longitudinal direction with respect to said attachment plate to change said locking means from an unlocked position to said locked position.

12. The support according to claim 11, wherein said attachment plate comprises at least one tang adapted to abut at least one of said plurality of projections at said locked position.

13. The support according to claim 11, wherein said base member further comprises a tightening member.

14. The support according to claim 13, wherein said tightening member is threading disposed on said support rod to adjust a tightening force between said base member and said attachment plate.

15. The support according to claim 11, wherein said key member is formed to congruously engage said aperture, at least one of said plurality of projections being adapted to pass through said aperture.
