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 snapconnected to the first hub section and frictionally engages the upper end of the post to prevent rotation of the echo chambers about the post.

sum 20$ 2 PERCUSSION MUSICAL INSTRUMENT 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. I

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 ceritral 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 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 4148 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 I2 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.
