Abstract
A rotary card holder comprises a rotary card wheel, which at its respective opposite ends is non-rotatably secured to hand wheels, with a stationary axle, about which the card wheel rotates, extending through the card wheel and the hand wheels and having secured non-rotatably to its opposite ends respective end caps with which respective free ends of a wire support frame are non-rotatably secured. Each end cap carries a flexible polypropylene strip which has a free end extending from the periphery thereof to engage in a selected one of a series of grooves in the inside periphery of the hand wheels. In this way the card wheel is retained in its adjusted position each time it is adjusted and a ‘clicking’ indication is produced during adjustment.
Claims42
A rotary card holder comprising a rotary member mounted by a support assembly for rotation relative thereto and having means for holding a plurality of cards, in use, manually operable means for turning the rotary member, and flexible means, between the support assembly and said manually operable means or said rotary member, the flexible means retaining the rotary member in a position to which it h been turned, in use, by said manually operable means, and including means for producing an audible indication as the rotary member turns, in use.
A holder as claimed in claim 5, wherein said hand wheel is non-rotatably fixed to said rotary member by a spigot of the rotary member being received in a boss of the hand wheel.
- 17.A holder as claimed in claim 16, wherein said end cap is non-rotatably fitted onto an end of an axle extending through the rotary member and about which the rotary member is rotatable, in use.
A holder as claimed in claim 17, wherein said end of the axle is non-rotatably received in a friction cap which is itself non-rotatably secured in a bore in a hub part of said end cap.
A rotary card holder comprising a rotary member mounted by a support assembly for rotation relative thereto and having means for holding a plurality of cards, in use, a hand wheel non-rotatably fixed to the rotary member, for turning it, and a material strip between the support assembly and said hand wheel or said rotary member, the strip having a free end which interferes with projections around an inner periphery of the hand wheel, when the rotary members is turned, in use, by the hand wheel, there by producing an audible indication as the rotary member turns, in use.
A rotary card holder comprising a rotary member mounted by a support assembly for rotation relative thereto and having means for holding a plurality of cards, in use, manually operable means for turning the rotary member, and flexible mean, between the support assembly and said manually operable means or said rotary member, the flexible means retaining the rotary member in a position to which it has been turned, in use, by said manually operable means, and producing an audible indication as the rotary member turns, in use, the support assembly comprising a wire frame having a base part to support the holder on a surface, in use, and respective spaced free ends engaged with end caps non-rotatably secured at the respective opposite ends of an axle extending through the rotary member for rotation of the rotary member relative to said axle, in use.
A rotary card holder comprising a rotary member mounted by a support assembly for rotation relative thereto and having means for holding a plurality of cards, in use, a hand wheel non-rotatably fixed to the rotary member, for turning it, the hand wheel being at one end of the rotary member and there being at a side of the hand wheel, remote from said one end, part of said support assembly, and flexible means acting between said hand wheel and said part of the support assembly, said part of said support assembly being an end cap which protrudes into an outer open side of the hand wheel, the flexible means retaining the rotary member in a position to which it has been turned, in use, by said manually operable means.
