Abstract
A price totem includes a carriage for carrying the display numbers at one or more vertical spaced number locations. The carriage has upper and lower portions which can be collapsed relative to each other enabling the construction of a large carriage which can still have its numbers changed at a single number changing station, which is accessible at ground level.
Claims21
An indicating mechanism for a price display device comprising a frame defining a vertical slideway, a carriage slidably mounted in the slideway for movement between a display position and a storage position, the carriage defining a plurality of vertically spaced number locations such that the locations can be successively disposed adjacent a number changing station as the carriage moves between its display and storage positions, characterised in that the carriage comprises upper and lower portions each bearing at least one number location, the portions being movably interconnected for relative vertical sliding movement whereby the carriage can be contracted into the storage position.
An indicating mechanism for a price display device comprising a frame defining a vertical slide way, a carriage mounted in the slideway for movement between a display position and a number change position adjacent a number changing station, the carriage defining a number location and counterbalance means for counterbalancing the weight of the carriage, including a pulley mounted on the frame above the carriage and a counterbalance weight connected to an upper part of the carriage by a flexible elongate member which passes over the pulley characterized in that the mechanism includes a further pulley located below the number changing station and a further flexible member connected to the weight, extending around the further pulley to the lower part of the carriage to form, with the carriage, a closed loop with the counterbalance means, whereby the carriage can be moved vertically in the desired direction by pulling on the further flexible member.
