ABSTRACT:
A record player turntable has a substantially flat circular metallic top and an integral substantially cylindrical downwardly extending metallic flange and a resilient mat having a circular top portion covering the aforesaid circular metal top portion and having an integral downwardly extending resilient flange gripping the said metallic flange. The connection between the horizontal metal turntable top and its connected vertically extending flange consists of an integral diagonal web of the metallic flange flared downwardly and outwardly. This web has grooves providing for a lodgment and gripping action on the part of the circular downwardly extending rim of the inverted pan-shaped plastic mat that covers the turntable top and it also forms part of the exposed substantially cylindrical lateral face of the turntable. A horizontally outwardly facing annular groove is formed in the aforesaid web adjacent its upper end, and an annular vertically upwardly facing groove providing a substantially square annular shoulder or bead remaining between said annular grooves is also formed in the web. The upper lip of the horizontal outwardly facing groove is preferably tapered externally downwardly and outwardly to assist expansion of the flange radially during application of the mat. A mat of organic composition of some elasticity (molded elastic polymeric material) has a disc-like top and a depending outwardly flaring frustoconical flange, the lower edge and margin of which flange is forced into the upwardly facing annular groove of the metal turntable, and simultaneously a substantially radially inwardly projecting rib on the inside surface of the depending flange of the mat is forced into the horizontally facing groove where said rib of the mat is held against vertical upward displacement partially by its circumferential grip in tension and, if desired, partly by the radial inward compression produced upon forcing the lower margin of the flange of the mat into the upwardly facing circular groove formed in the aforesaid web. The finished turntable gives the appearance of a thick plastic cushion bounded at its lower side edge by a polished metal band.
