BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a positioning foot for an instrument stand, and more particularly to a positioning foot having a spike alternatively extending out of the positioning foot to cope with different surfaces of performance sites.
2. Description of Related Art
A stand for a musical instrument is to support the music instrument, such as a drum, while the instrument is played. A firm grip to the performance surface is crucial such that the performer is able to play the instrument without any distraction. With reference to FIG. 9, a conventional stand (50) for musical instruments is shown and has legs (51) extending out from the stand (50). Each leg (51) is provided with a rubber sheath (60) surrounding the free end of the leg (51). Because the conditions of the performance sites vary, the rubber sheath (60) may not provide a firm grip to the performance surface and the stand may slide during the performance. Accordingly, the performer is not able to play the instrument without the interruption of correcting the stand.
To overcome the shortcomings, the present invention tends to provide an improved positioning foot to mitigate the aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an improved positioning foot for an instrument stand. The positioning foot has a spike alternatively extending out of the positioning foot such that the positioning foot is able to cope with different terrain and still provide stable grip to the performance surface.
Another objective of the present invention is to provide a positioning foot having a pad adapted to be securely mounted on a distal end of the stand leg to provide a firm grip to the surface.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1 and 2, the positioning foot for an instrument stand (10) having legs (11) extending out of the instrument stand (10) has a pad (20) and a spike (30).
The pad (20) is made of rubber and has a through hole (21) laterally defined through the pad (20) and two grooves (22) each oppositely defined in a side face of the pad (20).
The spike (30) is L-shaped and divided into an engaging end (31) and a connecting end (32). The engaging end (31) has a sharp distal end and the connecting end (32) has an outer thread formed on an outer periphery of the connecting end (32). A knob (33) has a hole (330) extending through the knob (33) to correspond to the connecting end (32) of the spike (30).
With reference to FIGS. 3 and 4, it is noted that when the positioning foot of the present invention is in assembly, the connecting end (32) is extended through the through hole (21) of the pad (20) and then the knob (33) is threadingly connected to the connecting end (32) of the spike (30), whereas the engaging end (31) is received in either one of the grooves (22) of the pad (20). Preferably, the leg (11) also has an extension hole (110) in alignment with the through hole (21) such that when the connecting end (32) is extended through the through hole (21), the connecting end (32) also extends through the extension hole (110) of the leg (11) (as shown in FIG. 4).
With reference to FIGS. 5, 6, 7 and 8, when the performance surface is slippery and the rubber pad (20) is unable to provide a firm grip to the surface, the operator may unscrew the knob (33) to loosen engagement between the engaging end (31) and an inner face defining the corresponding groove (22) and then push the knob (33) to allow the engaging end (31) to extend out of the groove (22). Downward pivotal movement of the spike (30) enables the engaging end (31) to point to the surface to be engaged. Thereafter, the operator tightens the knob (33) to secure the spike (30) to the pad (20). Thus the engaging end (31) engages with the performance surface and is able to provide a firm grip to the performance surface and the instrument stand (20) is able to stably support the instrument (not shown) thereon.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
