Definitions

  • the present invention relates to a method for pulling in towel loops and towel ends intended for drying on a towel dispenser, the towel being pulled from this towel roll from a towel roll with a fresh towel over a rotatably mounted feed roller by means of a weight roller lying behind a cover in a pull-in towel loop behind this cover a towel roll with used towel is wound according to CH-A-491 635, and on a device for carrying out the method.
  • part of a long cloth towel web hangs out of the dispenser in a loop.
  • the hands are dried on this loop. If the loop is pulled, a predetermined length of clean cloth towel comes out of the cloth towel dispenser; at the same time, the same length of fabric towel is pulled into the back of the dispenser so that the loop remains the same length.
  • This towel dispenser system has two hygienic disadvantages.
  • the first disadvantage can be seen after each hand drying: The damp, crumpled and often dirty stain in the towel resulting from drying remains visible to everyone until a fresh piece of towel is pulled on.
  • the second disadvantage shows up after the towel roll with the fresh towel has been used up: The end of the towel is pulled out of the dispenser at the front and hangs vertically downwards, sometimes even on the floor, when you let it go.
  • This hanging towel can and will - as practice shows - continue to be used for drying, whereby the cloth towel dispenser, designed as a disposable towel dispenser, is devalued as a hanging device for a "community towel " .
  • a towel tensioning and retraction device for use with a towel rail dispenser contains a weight and / or spring load of an inner towel loop.
  • the spring or weight load pulls the loop down and thus tightens it, even while the hands are drying. After the towel roll is used up, the end of the cloth towel is pulled inside the towel dispenser.
  • DE-A-1 958 891 describes a towel rail dispenser which is provided with an adjustable timer lock which is intended to prevent the towel loop from being pulled out too long.
  • the construction is relatively complicated and the towel loop hangs freely.
  • a shaft in a towel rail dispenser is temporarily blocked for two or more full rotations, the blocking period being adjustable by means of two suction cups adhering to one another by means of an air inlet valve.
  • This device also only determines the length of the pulled-out cloth, the towel loop used not being drawn in.
  • tissue towel dispensers in which the towel is pulled in by motor, so that both those from the last drying of the hands became dirty Place in the towel loop or pulled into the dispenser so that it is no longer visible, and also that the towel hanging down after the fresh towel roll has been used up completely disappears into the dispenser. With a mechanically retractable towel loop, this is also pulled while the hands dry, which is uncomfortable for the user.
  • the invention is therefore based on the object to eliminate the disadvantages of the known and to provide a method and an apparatus for pulling in towel loops and towel ends on a towel dispenser, in which the towel loop is drawn in only after a predetermined time for drying the hands, and with simple means and without the supply of external energy, i.e. without an electric drive, enable the pulling in of the cloth towel loop and the cloth towel end, whereby the device can either serve as an adapter for existing cloth towel dispensers or as a component of newly manufactured cloth towel dispensers.
  • the advantage of the invention is to be seen in that the towel is drawn in after each hand drying and the towel end is drawn in after the fresh towel roll has been used up and is only secured after a predetermined time.
  • the subject matter according to claim 2 for carrying out the method according to claim 1 relates to a device according to the preamble (cf. CH-A-491 635).
  • the object is achieved by the characterizing features.
  • the weight roller pulls the front part of the towel loop tightly towards the front of the dispenser and the bottom of the dispenser, and the rest of the loop disappears behind the cover.
  • the feed roller is expediently rough, so that the frictional force between the surface of the roller and the cloth towel is increased.
  • the friction wheel as a gear and the lever-shaped friction surface are formed by a lever with at least one tooth.
  • the device according to claim 4 has the further development that in the interior of the cover on both side walls of the cover guide strips for vertical insertion of the weight roller located in the towel loop are provided, that in addition one of these guide strips is attached as a horizontal obstacle strip to one of the side walls mentioned and that this guide bar, which is designed as an obstacle bar, engages in the vertical guide direction of the towel loop.
  • This design prevents the towel from being pulled out with the weight roller.
  • the cloth towel loop with the weight roller is first pushed up from its fall line in one pull, and the ends of the weight roller are stopped by these obstacle bars. This prevents the fabric towel from being pulled out with the weight roller.
  • At least one opening for removing the weight roller is expediently provided in the bottom of the cover and adjoins a side wall. This training ensures an easy way to take the weight roller out of the cover after the cloth towel has been used up.
  • the device according to the invention can be designed as an adapter for attachment under an already existing towel dispenser, which is of great economic importance, or that this device for a newly manufactured towel dispenser into the interior of this towel dispenser behind the cover of the towel dispenser fully or at least partially installed.
  • the device With the exception of the addition of the fresh towel, the device is maintenance-free and does not require any external energy, i. H. In particular, there are no installation and safety problems in the wet rooms.
  • the additional manipulation required when changing the towel roll is easy. It consists in pulling the weight roller lying on the bottom of the cover out of the cover, advantageously through the weight roller removal opening according to claim 6, in the bottom of the cover, and putting it back together with the towel loop behind the cover.
  • a cloth towel dispenser 1 known per se is provided with a cover 1 '.
  • This cover 1 ' is provided with a bulge 1 ", the task of which is to gain sufficient space between a cloth towel H and the cover 1' for touching the cloth towel H without having to touch the cover 1 'with wet hands
  • the cloth towel H is passed from a towel roll 2 with a fresh towel to a towel roll 3 with a used towel through a slot 4 for the exit of the fresh towel.
  • the towel roll 3 with a used towel is stored in the cover 1 'by means of a storage 3'.
  • This bearing 3 ' enables the axis of this towel roll 3 to be displaced while the diameter of this towel roll 3 is being enlarged.
  • the cover 1' of the towel dispenser 1 is provided at the bottom with a slot 5 for pulling in the used towel Towel loop, which is located outside the dispenser and is used for drying by hand symbolically represented as a circle and provided with an arrow indicating the direction of the train.
  • E is a stop mechanism known per se for limiting the pulling out of the cloth towel H.
  • a pull-in towel loop 7 is located behind a cover 9.
  • This cover 9 forms an interior 9 ', which has an extension 9 "in the area of the towel pull-in.
  • the towel H is passed from the towel roll 2 between a deflection roller A and a first roller B into the slot 4.
  • a second roller C is non-positively connected to the first roller B via a gear D. This means that when the deflection roller A is rotated by pulling the outer towel loop 6, the parts B, D, C the rotational movement on the towel roller Transfer the used towel 3.
  • the cover 9, which in turn is provided with a feed opening 12, is fastened in the area of the slot 5 to the lower part of the cloth towel dispenser 1.
  • a weight roller 10 is located in the feed towel loop 7. Both the top cover 1 'and the lower cover 9 are fastened to a wall 11.
  • Reference numeral 13 denotes a bottom of the cover 9 on which a buffer 33 is shown in simplified form.
  • FIG. 2 essentially corresponds to FIG. 1.
  • a towel end 8 is shown in broken lines.
  • the towel end 8 would hang freely from the cover 1 'if the pull-in towel loop 7 pulled with the weight roller 10 were not present.
  • the dotted line clearly shows one of the disadvantages of the prior art.
  • FIG. 4 shows a phase in which the outer towel loop 6 was tensioned again with the aid of the weight roller 10.
  • the towel dispenser 1 is prepared for further use.
  • FIG. 1 shows the phase in which the blocked feed roller 15 prevents the cloth towel H from being drawn in behind the cover 9 for a predetermined time interval and forms a conveniently usable towel loop 6 while the feed delay device 31 is operating.
  • the weight roller 10 is prevented by the blocked feed roller 15 from pulling in the towel loop 6 behind the cover 9.
  • the mechanism that causes this is housed in the area of the feed roller 15 and is shown in detail in FIGS. 6 to 10.
  • FIG. 6 shows in a perspective and schematic drawing the most important elements of a retraction device 35.
  • the cloth towel H wraps around the feed roller 15 at least in a quarter of the circumference.
  • the feed roller 15 is coated with an emery cloth. This has the effect that the cloth towel H adheres sufficiently to the feed roller 15 in order to transmit the forces necessary for the functioning of the feed delay device 35.
  • the friction wheel 19 is connected by a slip clutch 19, 17, 18 to the feed roller 15 via an axle 16 of the feed roller 15.
  • the slip clutch which in the example shown here consists of two friction flanges 17 and at least one friction clutch spring 18 that compresses them, is shown in a separate state for reasons of clarity.
  • friction flanges 17 press on both sides of the end faces of the friction wheel 19, the friction flanges 17 being slidably arranged on the parts of the journal 16 formed with a square profile and being under pressure from the friction clutch spring 18. Only the right friction clutch spring 18 is shown, the left one is not visible because it partly lies in the cavity of the round part of the journal 16 and is partly covered by the left friction flange 17.
  • the friction wheel 19 is rotatably mounted on a round part of the journal 16. As already mentioned, the friction wheel 19 is rotated on both sides with the friction flanges 17, as in a three-part friction clutch, until the friction wheel 19 stops, as will be described later.
  • the slip clutch 19, 17, 18 is adjusted so that when you turn the friction wheel 19, the weight roller 10 can be raised and lowered.
  • the journal 16 and a pin 37 of the lever 20 are mounted in a bearing plate 36.
  • the friction wheel 19 is in engagement with the lever 20.
  • This engagement part is shown in FIGS. 9 and 10 with abstracted components and in FIGS. 7 and 8 with practically realizable components, FIGS. 7 and 9 being the one end position and the one 8 and 10 show the other end position of the reciprocating lever 20.
  • the friction surface of the lever 20 is provided with the reference number 21. This friction surface 21 ends at point 22.
  • the center of gravity 23 of the lever 20 according to FIGS. 9 and 10 illustrates that it is pulled to the right by its own weight G.
  • the lever 20 is a sector of a large friction wheel. According to the rest position shown in FIGS. 7 and 9, it is not in engagement with the friction wheel 19, but thanks to its appropriately arranged center of gravity 23 it leans against the friction surface 24 of the friction wheel 19 with one end 22 of the friction surface 21.
  • the distance that the cloth towel H has to travel to bring the lever 20 into the position just described is relatively short. If more is pulled out of the opening 12 of the cover 9 than is necessary for the lever actuation, the friction clutch begins to play. That is, the feed roller 15 continues to rotate, but the friction wheel 19 stops. The friction wheel 19 tries to turn the lever 20 because, as shown in FIGS. 8 and 10, it is still engaged. This, however, remains pressed against the stop 29 in this position.
  • the weight roller 10 begins via the fabric towel H on the feed roller 15 and from here on that of the smaller torque, due to the blocked friction clutch again, on the friction wheel 19, and thus on the lever 20 to act. This force tries to move the lever 20 to its rest position. However, it can only do this when the suction cups 26 and 27 have come loose due to the penetration of air between them.
  • suction cups 26 and 27 are provided with an adjustable air supply (valve) known per se, the period of time during which the towel loop 6 should exist can be regulated.
  • the friction wheel 19 and the lever 20 can also be replaced by a gear and a toothed segment lever.
  • This device consists of guide strips 30 and 31, which are each attached to the inside of the two side walls 32 of the lower cover 9 directly below the feed opening 12 of the lower cover 9.
  • Towel loop 7 They are sized to feed Towel loop 7 can slide past them undisturbed, but which detects the somewhat wider weight roller 10.
  • the weight roller 10 lying in the pull-in towel loop 7 is inserted at the top through the opening 12 behind the cover 9, the weight roller 10 is forced forward by the guides 30 and then again by the guides 31 into the center of the shaft-shaped space.
  • the cloth towel H glides undisturbed past the guides 30 and 31.
  • FIG. 13 shows a front view of the lower part of the pull-in towel loop 7 with the weight roller 10.
  • the solution according to the invention can easily be integrated into sanitary units.
  • an entire washing unit can be equipped in an aesthetically perfect way from a washbasin, soap dispenser, towel dispenser together with the feed mechanism according to the invention.
  • the lower cover 9 of the towel loop 7 with the weight roller 10 can be realized in the simplest way, also as previously shown, as a shaft or in the manner of a shaft.
