  • Patent number: 4472606
    Abstract: This invention relates to a holder and mounting arrangement which can be mounted at any angle to various surfaces, for use with a radio telephone handset. Operation of the holder will permit insertion or removal of the handset from either end. The geometry of the retainer member allows pivoting action of either pair of spring washer set which enables the user to lift either the front or rear edge of the handset to clear the recess and slide it free of the guiderails for operation. The assembly is adaptable to various mounting surfaces within the passenger compartment of any vehicle. During operation, the grooved handset is inserted between the top rails of the retainer member and pushed along the guiderails, which lifts the retainer member against the spring load of the captivated spring washers until the handset is seated in the associated central cavity of the base member.
