DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD AND BACKGROUND OF THE INVENTION
The invention relates to a towel dispenser, particularly for hand-drying.
There is the need in towel dispensing for the loop or the like exposed for use, connecting the clean portion to the soiled portion of the toweling web and permitting subsequent incremental dispensing, to be taken up or shortened and thus make it ready for permitting dispensing of a fresh towel portion in extending the length of the loop, whereby the loop may hang down non-tensioned for a predetermined time or may be continuously subjected to the tension of a take-up force so that after being released by the user it is immediately taken up.
OBJECTS OF THE INVENTION
The invention is based on the object of defining a towel dispenser in which the disadvantages of known configurations are avoided and which, more particularly, offers the possibility of ensuring an effective take-up in many of its different operating conditions and/or to permit simple handling.
SUMMARY OF THE INVENTION
In accordance with the invention the toweling web can be dispensed from a clean storage and, depending thereon, transferred into one or more soiled storages, towel dispensing expediently operating a toweling take-up, a loop take-up and/or an energy storage, the stored energy of which serves to tensioningly pull the loop to the dispenser, e.g. on timeout of a timer, or to take over a soiled portion of the toweling loop into the final soiled storage. The timeout of the timer may commence during or after dispensing of the clean toweling portion to the loop.
Preferably, the energy storage is charged manually or by pulling-down the toweling web so that it always contains sufficient energy, irrespective of the operating condition of the dispenser, to take up the loop or to transfer the last trailing end of the toweling web totally into the cabinet. Such an operating condition may also be the one which is provided for extracting the soiled toweling web or for inserting a fresh toweling web or it may be the one resulting when the last end of the clean toweling web is totally taken up or transferred into the soiled storage, namely e.g. wound up. Expediently, the energy storage for each towel dispensing action is charged so that the energy stored thereby is sufficient for taking up a length of toweling web which is at least 10% greater than the toweling web length dispensed immediately before.
To prevent overcharging of the energy storage thereby, e.g. a mechanical spring storage having a tensioned storage spring, expediently an overtensioning safeguard is provided. In the case of a spiral spring at least one end may be defined by friction only, so that it is moved on loading with respect to the input/or output drive transfer member connected thereto, thus making a further tensioning of the spring no longer possible whilst, however, retaining the maximum possible spring tension.
To avoid take-up or to retain the stored energy or in corresponding operating conditions, the energy storage or the take-up mechanism is expediently blocked from outputting energy. If, e.g. the take-up mechanism is not subjected to the holding effect by the toweling web, expediently a corresponding blocking action is engaged. For this purpose a sensing or strobe member may be provided which senses the presence of the toweling web upstream of the soiled storage or of a drivable take-up roller in a passage slot or downstream of the intake position of the associated loop leg into the dispenser and, when not present, to engage the blocking. The sensing member may, however, also sense the operating status of the dispenser mechanically, namely e.g. whether both slot limits in the using position are closely located together or separated from each other e.g. so that the toweling web can be replaced, i.e. in this case too, a blocking being provided. As a result of this the energy storage is discharged neither when the toweling web is totally taken up nor when the dispenser is opened so that after having inserted a fresh toweling web sufficient drivi
