Abstract
Abstract A percussion instrument comprises an oblong plastic block having a generally rectangular block portion with a front face and top and bottom surfaces, and a flange extending outwardly from the sides and rear. An elongated slot in the front face extends rearwardly to the rear flange, and laterally between the side flanges. The block has a raised ridge on the top face adjacent the front face for striking. In addition, landings are formed in the flanges which, together with a cooperating bracket assembly, act as a means for mounting the block.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
A percussion instrument in the form of an oblong, plastic block comprising: a generally rectangular block portion having front, top, and bottom faces and an elongated slot in the front face extending substantially the width and depth of the block portion; a flange extending outwardly on either side and to the rear of said block portion, said flange including at least one mounting means; and a raised striking ridge extending along the top face adjacent the front face.
Claim 2
Dependent Claim
78 words
A percussion instrument in the form of an oblong, plastic block comprising: a generally rectangular block portion having front, top, and bottom faces and an elongated slot in the front face extending substantially the width and depth of the block portion; a flange extending outwardly on either side and to the rear of said block portion, said flange including at least one mounting means; and a raised striking ridge extending along the top face adjacent the front face.
Claim 3
Dependent Claim
58 words
An instrument as defined in claim 1, wherein said flange is formed of a plurality of outwardly tapered flange sections including a pair of laterally oriented side flange sections, a rearwardly oriented rear flange section, and a pair of connecting flange sections between the rear and side flange sections and oriented at approximately a 45° angle relative thereto.
Claim 4
Dependent Claim
45 words
An instrument as defined in claim 2, wherein the mounting means comprises a landing formed in each of the side flange sections and the rear flange section, each landing being defined by parallel top and bottom surfaces, and wherein each landing includes a hole therethrough.
Claim 5
Dependent Claim
33 words
An instrument as defined in claim 3, wherein each of the flange sections is frusto-conical in cross-section to define a vertical, outside face, and wherein said landings extend inwardly from said outside faces.
Claim 6
Dependent Claim
19 words
An instrument as defined in claim 4, wherein said ridge, in cross-section, has substantially a rearwardly extending teardrop shape.
Claim 7
Dependent Claim
94 words
An instrument as defined in claim 3, wherein the mounting means further comprises a mounting bracket means including a flat, plate portion shaped to be selectively received in said landings and positioned against one of the landing surfaces, said plate portion further having bolt-receiving means, aligned with the landing holes, and bolt means having a threaded portion insertable through the hole of the landing into the bolt-receiving means of the plate portion, and further having a head for bearing against the other surface of the landing for securing said bracket means to said landing.
Claim 8
Dependent Claim
82 words
A percussion instrument in the form of an oblong, plastic block, comprising: a generally rectangular block portion having front, top and bottom faces and an elongated slot in the front face extending substantially the width and depth of the block portion; a flange extending outwardly from at least one of the two sides and the rear of said block portion, said flange including at least one mounting means; and a raised striking ridge extending along said top face adjacent said front face.
Claim 9
Dependent Claim
82 words
A percussion instrument in the form of an oblong, plastic block, comprising: a generally rectangular block portion having front, top and bottom faces and an elongated slot in the front face extending substantially the width and depth of the block portion; a flange extending outwardly from at least one of the two sides and the rear of said block portion, said flange including at least one mounting means; and a raised striking ridge extending along said top face adjacent said front face.
Claim 10
Dependent Claim
44 words
An instrument as specified in claim 7 wherein said flange comprises at least one outwardly tapered flange section and wherein said at least one mounting means comprises a landing formed in said flange section, said landing being defined by parallel top and bottom surfaces.
Claim 11
Dependent Claim
136 words
A percussion instrument in the form of an oblong, plastic block, comprising: a generally rectangular block portion having front, top and bottom faces and an elongated slot in the front face extending substantially the width and depth of the block portion, said slot being spaced closer to one of said top and bottom faces than the other forming unequal wall thicknesses between said slot and said faces; and a flange integral with said block portion extending outwardly from at least one of the two sides and the rear of said block portion, said flange including at least one mounting means, said flange comprising at least one outwardly tapered flange section and wherein said at least one mounting means comprises a landing formed in said flange section, said landing being defined by parallel top and bottom surfaces.
Claim 12
Dependent Claim
136 words
A percussion instrument in the form of an oblong, plastic block, comprising: a generally rectangular block portion having front, top and bottom faces and an elongated slot in the front face extending substantially the width and depth of the block portion, said slot being spaced closer to one of said top and bottom faces than the other forming unequal wall thicknesses between said slot and said faces; and a flange integral with said block portion extending outwardly from at least one of the two sides and the rear of said block portion, said flange including at least one mounting means, said flange comprising at least one outwardly tapered flange section and wherein said at least one mounting means comprises a landing formed in said flange section, said landing being defined by parallel top and bottom surfaces.
Claim 13
Dependent Claim
24 words
An instrument as specified in claim 9 wherein said flange extends outwardly from both of said sides and said rear of said block portion.
Claim 14
Dependent Claim
19 words
An instrument as specified in claim 9 wherein said unequal wall thicknesses are in the ratio of approximately 2:1.
