DESCRIPTION:
BRIEF SUMMARY
This invention relates to a lectern or stand which is primarily intended for use by musicians providing a support for receiving sheet music or full score. The prior art is exemplified by one known construction of fully folding music stand comprising a tripodal base carrying a vertical column on which is mounted a support for music formed from a number of pivotally interconnected slats which allow the support to be folded for storage or carriage. This known construction is relatively flimsy and in particular is easily knocked over. In addition, the structure is not substantial enough to be of use to conductors who require a stand or lectern of a more stable nature. In addition, the known construction is quite difficult to erect and collapse and can catch the user's fingers. Moreover, it is fixed in position by thumb screws in threaded metal holes which wear out and there is no special arrangement for carrying it.
One of the objects of this invention is to provide a lectern or stand which has improved stability and which may be collapsed into neat component parts to fit into a music case, and in particular into a specifically designed carrying case.
Broadly, and in accordance with one aspect of this invention, there is provided a stand for supporting music or the like comprising a tripodal base member including three legs each pivotally connected connected at their one ends to a base couple, a vertical support column with a lower section slidably embraced by the base coupling, each leg having a strut pivotably connected at one end to an intermediate point on the leg and at the other end to a lower part of the lower section of the vertical support column, whereby the legs may be swung from a first stored position in which they lie in parallel juxtaposed relationship when the base coupling is remote from the lower part of the vertical support to an extended in use position to form a tripod structure when the base coupling is moved adjacent said lower part, the column comprising a plurality of telescopically slidable sections with the topmost section including a connector for element with a support, the connector permitting relative angular adjustment between the support and telescopic column.
Although the construction described and claimed herein refers to a tripod base member it is to be understood that four, or more, legs could be provided without departing from the essence of this invention.
Preferably the lower telescopic section is slidable within the base coupling and tie legs are capable of inward pivoting so as to lie parallel and circumferentially around the said lowermost telescopic member.
An advantage of adopting a construction of this nature is that when the three ground support legs are folded inwardly to lie in parallel relationship, the cross section between said legs may accommodate the lowermost section of the telescopic support with the length of this section being comparable to the length of the legs. The further telescopic sections all nest within the lower section and thus the overall length of the stand may be significantly reduced to a dimension which enables same to be accommodated within a case specifically designed for holding sheet music as example.
The support for the music may comprise a rigid rectangular plate or board and includes a means permitting releasable coupling with the connector end of the uppermost telescopic section. The connector permits angular adjustment such that the facing plane of the support may be positioned at the most convenient angle for a user.
Further and preferred features of this invention will be described in conjunction with the accompanying drawings which show one constructional embodiment by way of an example.
Referring to the drawings:
Figure 1 shows the music stand in an in use position,
FIG. 2 shows the tripod support part in a collapsed position,
FIG. 3 shows the tripod support with the telescopic sections extended but with the legs collapsed,
FIG. 4 is a view as in FIG. 3 but with the legs in the open in use position,
FIGS. 5 to 7 show details
