PERCUSSION MUSICAL INSTRUMENT
Abstract
A percussion type musical instrument is formed as a
representation of a flower having radiating petals. Each petal
consists of an open bottom echo chamber and an elliptical tone bar
secured to the top of the chamber by snap-type fastening means
formed integrally with the chamber. The chambers are integrally
formed with a hub section mounted to a downwardly extending
stem-like post. Another hub section or cap is snap-connected to the
first hub section and frictionally engages the upper end of the
post to prevent rotation of the echo chambers about the post.

Description
This invention relates to percussion musical instruments in
general, and more particularly relates to a novel construction for
a xylophone-type instrument.
Conventional xylophones are constructed of rectangular bars and
resonators arranged in a row. As a practical matter this prior art
construction has proven to be relatively bulky and costly.
In contrast, the device of the instant invention comprises
elliptical tone bars, each mounted to the top of an elongated open
bottom echo chamber constituting an arm radiating from a hub
element. The hub element and all of the arms are integrally formed
of molded plastic material. Also integrally molded with the arms
are L-shaped holding elements which secure the tone bars to the
arms. This radiating circular array of elliptical tone bars is
arranged to simulate the petals of a flower, thereby resulting in a
musical instrument of novel appearance.
Accordingly, a primary object of the instant invention is to
provide a percussion type musical instrument of novel
construction.
Another object is to provide a musical instrument of this type in
which the tone bars are elliptical.
Still another object is to provide a musical instrument of this
type in which the echo chambers are integrally formed with a hub
section and holding means for mounting the tone bars.
A further object is to provide a musical instrument of this type
which is relatively compact and inexpensive to construct.
These objects as well as other objects of this invention will
become readily apparent after reading the following description of
the accompanying drawings in which:
FIG. 1 is a perspective of a musical instrument constructed in
accordance with teachings of the instant invention.
FIG. 2 is a vertical cross-section through the musical instrument
of FIG. 1.
FIG. 3 is a plan view of the echo chamber member.
FIG. 4 is a cross-section taken through line 4--4 of FIG. 3 looking
in the direction of arrows 4--4.
FIG. 5 is a plan view of one of the elliptical tone bars.
FIG. 6 is a fragmentary cross-section taken through line 6--6 of
FIG. 2 looking in the direction of arrows 6--6.
FIG. 7 is a bottom view of the hub cap member.
Now referring to the figures. Musical instrument 10 includes
plastic pot 11 having horizontal partition 12 which simulates soil
level in pot 11. Partition 12 is provided with a central aperture
through which stem or post 13 extends, with the lower end of post
13 being frictionally engaged by the interior walls of circular
recess 14 provided inside of pot 11 at the bottom thereof.
Two-petal plastic leaf member 15 is disposed with its central
connecting portion 16 adjacent the upper surface of partition 12.
Post 13 extends through a central aperture in connecting portion 16
and is frictionally engaged by the walls of this aperture.
The upper end of post 13 is entered into the central aperture in
downward extension 17 of cap or hub section 20. The latter is
constructed of plastic material and is provided with four holding
elements 18 entered into apertures 21 in hub section 22 of echo
chamber member 25. Elements 18 are disposed behind ledges 23 to
hold cap 20 in its operative position. Interior slot 24 in hub
section 22 receives complementary rib 26 (FIG. 7) in cap 20 to
establish the relative angular position between hub sections 20 and
22. Radiating from hub section 22 and formed integrally therewith
are eight equally spaced arms 31-38. The arms are graduated in
length, with arm 31 being the longest and arm 38 being the
shortest. Each of the arms 31-38 is formed as an elongated open
bottom echo chamber. At the top of each arm 31-38 are a pair of
inverted oppositely facing L-shaped holding elements 51, 52 formed
integrally therewith.
Holding elements 51, 52 extend into the respective apertures 53, 54
in each of the eight elliptical tone bars 41-48 constructed of
metal sheet material. The spacing between apertures 53 and 54 for
each of the tone bars 41-48 is such that it corresponds to the
spacing between only a single set of holding elements 51, 52 so
that each of the tone bars 41-48 is mounted to the proper echo
chamber arm 31-38, respectively. An annular felt pad 57 is mounted
to each holding element 51, 52 to provide a soft resting place for
tone bars 41-48 and spaces them slightly above the upper surfaces
of echo chamber arms 31-38. However, the major spacing function is
achieved by ribs 58 formed on the upper surfaces of arms 31-38
adjacent holding elements 51, 52. This mounting of tone bars 41-48
to arms 31-38 is in a loose fashion so that each tone bar 41-48 is
free to vibrate at its characteristic frequency when struck by head
63 of hammer 65. Preferably, each of the tone bars is constructed
of anodized aluminum.
Both hub cap 20 and echo chamber member 25 are molded of high
density polyethylene so that holding elements 18, 51, 52 are
deflectable from their normal holding positions, and return to
these normal positions after deflecting forces are released to act
as snap-type retaining means. It is noted that the orientation of
hub cap extension 17 is such that with post 13 held vertical, the
plane containing echo chamber arms 31-38 is inclined so that the
tone bar having the lowest characteristic frequency (longest tone
bar 41) extends to a higher point than any of the other tone bars
42-48.
Partition 12 is also provided with aperture 61 which removably
receives handle 62 of hammer 65. Hammer head 63 is designed to
simulate a bee and includes wooden body 64 and plastic wings
66.
Thus it is seen that the instant invention provides a novel
construction for a percussion-type musical instrument including a
set of elliptical tone bars arranged in circular radiating fashion
to simulate the petals of a flower. All of the echo chambers are
integrally formed of molded plastic material, with the molding also
including hook-like holding elements for maintaining the tone bars
mounted to their respective echo chambers.
Although there have been described preferred embodiments of this
novel invention, many variations and modifications will now be
apparent to those skilled in the art. Therefore, this invention is
to be limited, not by the specific disclosure herein, but only by
the appending claims.
