This invention relates to backboards for use. in basketball games and the like. .The main purpose of the invention is to provide a board which is light and durable, and has the desirable characteristics of woodlboards, but still is not subject to warping or cracking, and which presents a perfectly plain and hard surface. In thisrespect the improved board is not inferior to glass boards but avoidsthe weight and fragile characteristics of boards of that class. x V
A further object of the invention is to provide a basket-ball back-board having a core 7 of softer, lighter and more resilient 'material than its surface material or casing, and
thus to combinelth'e desirable qualities of resilience and lightness with a good wearing surface. g 1
An illustrative embodiment of. this invenin the accompanying drawings in which I Figure. 1 isa perspective view of a baskee ball goal, showing the Wall, the backboard V mounted on the wall, and the basket mounted on the board in the manner required by the (rules of the game of basket-ball, V

The invention may be carried out by the use of manufacturedboards wherein a fibrous I core is sheathed in metaL- The core is preferably formed of a plurality of veneer'sheets andis covered with a non-corrosive metallic casing, all compactly pressed together.
Referring to the drawings, the backboard 1 consists of a wooden laminated body portion 2 which is covered by a sheet metal casing consisting of a sheet 3 which is glued to the .back of the body portion, and the sheet 4 which is glued to'the face of the body portion 1 2.- The'sheet 4 is bent around the edges of I 59 interiorv board.
