Abstract
Abstract An improved racquet construction for paddle ball games and the like including a pair of spaced-apart opposed striking faces having sandwiched therebetween a honeycomb-like network comprising a light weight, high strength composition, especially aluminum. The honeycomb network conforms generally to the blade configuration and extends integrally into a handle portion for the racquet to become a part thereof. An edging strip, preferably comprising aluminum, is provided at the periphery of said sandwich construction and extends into said handle portion. The sandwich construction may be maintained by means of a suitable adhesive whereby said striking faces may be bonded to said edging strip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
263 words
A bat for paddle ball games and the like comprising a substantially rigid composite construction including a blade portion and a handle portion said blade portion being so dimensioned as to define an area which comprises a substantial majority of the area of said bat with said handle portion extending outwardly from said blade portion in substantially the same plane thereof and being so dimensioned as to define the remaining area of said bat, said blade portion comprising a pair of generally parallel, spaced-apart substantially solid, planar striking members having sandwiched therebetween a honeycomb-like network of a lightweight metallic composition, said honeycomb-like network having walls which are substantially perpendicular to said members at substantially all points of contact therewith and which form openings which are covered by said striking members, said honeycomb-like network conforming generally to said blade portion configuration and being slightly smaller than said striking members thereby forming a peripheral margin of space between the outer peripheral edges of said honeycomb-like network, an edging strip for said bat provided in said peripheral margin, said honeycomb-like network, each of said striking members, and said edging strip extending substantially the length of the handle portion for said bat and forming an integral part thereof, said edging strip engaging and being secured to the outer peripheral edge of each of said striking members, and means disposed on the handle portion for gripping the bat, whereby the bat is sufficiently rigid to withstand high-velocity impact of a Heavy ball of the paddle ball type without significant fulcruming of the blade portion about the handle portion.
Claim 2
Dependent Claim
263 words
A bat for paddle ball games and the like comprising a substantially rigid composite construction including a blade portion and a handle portion said blade portion being so dimensioned as to define an area which comprises a substantial majority of the area of said bat with said handle portion extending outwardly from said blade portion in substantially the same plane thereof and being so dimensioned as to define the remaining area of said bat, said blade portion comprising a pair of generally parallel, spaced-apart substantially solid, planar striking members having sandwiched therebetween a honeycomb-like network of a lightweight metallic composition, said honeycomb-like network having walls which are substantially perpendicular to said members at substantially all points of contact therewith and which form openings which are covered by said striking members, said honeycomb-like network conforming generally to said blade portion configuration and being slightly smaller than said striking members thereby forming a peripheral margin of space between the outer peripheral edges of said honeycomb-like network, an edging strip for said bat provided in said peripheral margin, said honeycomb-like network, each of said striking members, and said edging strip extending substantially the length of the handle portion for said bat and forming an integral part thereof, said edging strip engaging and being secured to the outer peripheral edge of each of said striking members, and means disposed on the handle portion for gripping the bat, whereby the bat is sufficiently rigid to withstand high-velocity impact of a Heavy ball of the paddle ball type without significant fulcruming of the blade portion about the handle portion.
Claim 3
Dependent Claim
22 words
A bat as set forth in claim 1 wherein said honeycomb-like network and each of said striking surfaces comprise an aluminum composition.
Claim 4
Dependent Claim
246 words
A bat for paddle ball games and the like comprising a substantially rigid composite construction including a blade portion and a handle portion, said blade portion being so dimensioned as to define an area which comprises a substantial majority of the area of said bat with said handle portion extending outwardly from said blade portion in substantially the same plane thereof and being so dimensioned as to define the remaining area of said bat, said blade portion comprising a pair of generally parallel spaced apart substantially solid, planar striking members having sandwiched therebetween a honeycomb-like network of lightweight metallic composition, said honeycomb-like network having walls which are substantially perpendicular to said members at substantially all points of contact therewith and which form openings which are covered by said striking members, said honeycomb-like network conforming generally to said blade portion configuration and being slightly smaller than said striking members thereby forming a peripheral margin of space between the outer peripheral edges of said honeycomb-like network, an edging strip for said bat provided in said peripheral margin and engaging the outer peripheral edge of each of said striking members, said honeycomb-like network, each of said striking surfaces and said edging strip extending substantially the length of the handle portion for said bat and forming an integral part thereof, whereby the bat is sufficiently rigid to withstand high-velocity impact of a heavy ball of the paddle ball type without significant fulcruming of the blade portion about the handle portion.
Claim 5
Dependent Claim
