Description

The invention relates to a device with disinfectant dispensing function, in particular a door handle, an operating handle, a keyboard accessory device or the like. According to the preamble of claim 1

Such a door handle is, for example, with the subject of KR 20160063660 A1 become known, in which by touching a door handle a jet of a disinfectant spray is discharged against the hand.

This door latch consists of a jacket tube with a recess in which a spring-loaded handle is arranged, which is connected at one end to an actuating pin which acts on the discharge end of a liquid nozzle, which is arranged at the front end of a cartridge filled with a liquid.

Upon actuation of the spring-loaded lever, the pin actuates the dispensing valve on the liquid container and opens the valve, which dispenses a disinfecting liquid over a channel extending along the lateral surface of the door handle.

Disadvantage of this arrangement is that a liquid container filled with an overpressure is assumed, which means that the storage and the arrangement of the disinfecting liquid in a container filled with overpressure is difficult and costly.

Another disadvantage is that the operation is cumbersome and not reliable, because only an actuating pin is directed against the nozzle of the cartridge by the spring-loaded pivoting handle, which in turn is then opened and emits the disinfectant via a channel.

This has the further disadvantage that it depends on a good seal between the discharge end of the cartridge and the subsequent liquid channel, which is not always secured. In addition, this sealing compound can pollute or fail.

Another disadvantage is that the disinfectant is discharged only under the influence of the pressure in the container in a longitudinal direction of the doorknob channel, whereby a non-uniform distribution of the disinfectant over the surface of the doorknob is given and the further disadvantage is that in this area between Channel and the discharge end of the channel disinfectant may remain, which may be encrusted or dirty.

Therefore, the disinfecting effect of the known arrangement is not sufficient and not safe to operate.

With the subject of US 2006/0267299 A1 a device for disinfecting push rods of shopping carts has become known, in which a metering valve is actuated spring-loaded due to a push of a button, a disinfectant liquid removed from a liquid container and applied to a non-woven paper, so that the possibility exists that by reciprocating the device along the push bar a disinfection of the push bar is possible. Disadvantage of this arrangement is that the shopping cart with continuous push rods rarely occur, so that the application of such a device is limited.

Another disadvantage is that the housing is large and is not suitable for disinfecting the palms of a user, but only for disinfecting the push bar of the shopping cart. This has the disadvantage that users with contaminated hands decontaminate the push bar and thus the cleaning effect is called into question.

With the subject of WO 2013/153168 A1 a door handle according to the preamble of claim 1 is shown, in which a cantilevered pivoting lever operates with its free pivotable end on a double-acting metering valve, which removes a disinfecting liquid from a container and sprayed via a spray nozzle against the inside of the handle.

This has the disadvantage that when gripping the handle, only the finger outer sides of the hand are disinfected, but not the palms, which are usually subject to greater pollution.

Another disadvantage is the relatively long channel guide after the arranged at the operating end of the pivot lever metering valve is dependent on long hose-bound supply paths to supply the arranged in the interior of the liquid container liquid to a spray nozzle.

Another disadvantage of the cited document is that it is the handle is not a doorknob, but a bow handle, which is mounted pivotally, which can lead to surprise moments when a user a door or another container with such a bow handle wants to open. The Surprise moment is that the bow handle is not fixed, but just in one side is pivotally mounted, which can lead to irritation in the operation.

This has the disadvantage that the operation of the bow handle is not possible when opening a container, but only when closing, namely, when a corresponding closing pressure is exerted on the bow handle so that it pivots about its pivot bearing in a closing direction and so that its actuating end acts against the arranged at the operating end metering valve.

Thus, only the delivery of a spray when closing a container is possible, but not when opening.

The invention therefore has the task of starting from the WO 2013/153168 A1 to develop a device with disinfectant dispensing function so that a reliable delivery of a disinfectant in any direction of actuation of the device is possible and that further ensures a reliable delivery of a disinfectant in the smallest space.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

According to a preferred feature, it is provided that the liquid container is received in a secured position in the hollow profile of the jacket tube and that the jacket tube is at least partially surrounded on its outer periphery by the pivot lever. This results in a particularly space-saving design.

Another preferred feature of the invention is that the device, in particular the door handle or the operating handle or keyboard accessory device are formed as a jacket tube, in the interior of which a liquid container is received, in or on which a metering valve is arranged and that the device in its formation as a jacket tube the doorknob or the actuating handle or the keyboard accessory is at least partially overlapped by a pivot lever which is connected to an associated actuating button which is adapted to act on the disposed on or in the liquid container metering valve.

Under a doorknob, the invention understands a one-sided latch handle. Under an operating handle, the invention means all known types of actuation for the operation of machines and devices, in particular stirrup handles, swivel or push handles, knobs, rotary lever and the like. Under a keyboard accessory device, the invention means an accessory to a keyboard or a keyboard-receiving device on the disinfectant accessory is detachably or permanently attached.

When the realization of the invention in the form of a door handle is described in the following description, this is not to be understood as limiting. This is done for the sake of simplicity of description. The following description therefore applies to all parts mentioned above.

Advantageous feature of the invention is therefore that a conventional door handle or an operating handle is replaced by a special door handle or a special operating handle, wherein the operating handle or the door handle is formed as a hollow tubular casing, in the interior of a form-adapted liquid container is inserted and fixed there, wherein on or in the liquid container, a double-acting metering valve is arranged, which in its construction according to a metering valve 7 of the US 2006/0267299 A1 equivalent.

With the formation of the doorknob in the manner of a hollow casing tube, in which a liquid container is used, in which the metering valve is integrated either inside or outside, there is the advantage of a small footprint, because now the doorknob is hollow according to the invention and as Recording space for the liquid container is used.

The actuation of the metering valve via a pivot lever, as in principle from the WO 2013/153168 A1 is known, however, the essential difference in the invention is that the pivot lever is preferably designed as a half or quarter or Achtel round tube, which is adapted to the outer diameter of the jacket tube and the jacket tube partially positively surrounds with game, so that so lowest possible height is achieved.

The pivot lever is therefore adapted to the shape of the doorknob and therefore requires no further space and is therefore not comparable to the bow handle, as in the WO 2013/153168 A1 has been described.

Thus, a favorable operation is achieved in the smallest space, because instead of the operation of the doorknob itself is now touched by hand on the pivot lever, which preferably corresponds in its contour, shape and color of the doorknob, and thus the pivot lever is spring-loaded by a small amount operated against an associated pivot bearing, wherein the spring is compressed. This will be a on the inside of the Swivel lever arranged actuating button pressed against the metering valve, and the metering valve is actuated thereby and promotes a liquid jet out of the liquid container.

It is advantageous that the liquid container directly a spray nozzle is attached, the liquid-conducting into the interior of the liquid container into it therefore there are no long fluid transmission paths and no channels that could pollute or crust.

Thus, from the directly on the liquid container arranged spray nozzle, a spray is discharged upward through a suitable recess in the jacket tube and passes through another, approximately aligned thereto arranged recess in the pivot lever and thus reaches the inner surface of the palm.

Thus, the advantage is achieved that no longer the fingers are wetted from the outside, as with the WO 2013/153168 A1 the case is, but that the inside of the palm is disinfected, which is associated with particular advantages in terms of the disinfecting effect.

Another advantage is that can be driven at a wetted palm along the door handle to achieve even a further distribution of the disinfectant on the handle designed as a pivot lever.

This achieves a large-area distribution of the disinfectant via the pivoting lever. At the same time, larger areas of the hand are wetted with the disinfectant.

This achieves a superior wetting effect and an improved disinfecting effect on account of the advantages according to the invention.

In an advantageous embodiment, it is provided that the liquid container is elastic in itself, z. B. consists of a strong film as z. B. in refill containers for soaps and the like are known.

In another embodiment, it can be provided that the liquid container consists of a relatively rigid plastic material, which has on the actuating side an approximately window-shaped actuating surface, which is sealingly covered with a flexible membrane. The size of the actuating surface may correspond to that of a cent piece.

The actuating button of the pivot lever then presses on the flexible membrane and displaces it elastically into the interior of the liquid container. It can also be arranged on the inside of the flexible membrane Betätigungsnoppe, which operates directly on the arranged in the interior of the liquid container, double-acting metering valve.

Of course, it is possible that the actuating knob eliminates the flexible diaphragm and the flexible diaphragm directly actuates the metering valve.

The double-acting metering valve sucks on actuation spring-loaded via a first check valve liquid out of the interior of the liquid container and promotes this due to the pressure load in an ejection space, where it is supplied to the spray nozzle and is injected via a second check valve from the spray nozzle.

As stated above, such a double-acting metering valve is in the US 2006/0267299 A1 described in detail and is to be used for the purposes of the present invention.

In another embodiment of the invention, it may be provided that instead of the one-sided pivot bearing of a semicircular or at least profiled pivot lever whose profile is adapted to the outer profile of the casing tube, now a flexible tube is used, which instead of the pivot bearing a flexible pivotal connection to the Casing tube has.

Thus, the trained as a partial tube pivot lever is resiliently formed in itself and can be operated directly as a spring plate omitting the return spring.

In a further embodiment, it can be provided that the arrangement according to the invention is also provided for attachment to push rods of shopping carts. The same device described above is used, i. H. it is the jacket tube clamped onto the push rod, and then sits on the radially outer side of the jacket tube, the liquid container, which is covered by a jacket tube covering about quarter-tube or semi-tubular pivot lever.

Here, too, a clipping of the device on the push bar of a shopping cart can be done and a disinfection as soon as the palm is pressed onto the semi or quarter tubular pivot lever so that then from the liquid container, a spray against the (inside) palm is delivered.

Likewise, it is possible in a further development that not the pivot lever is designed as a cantilevered pivot lever, but as a plate which has no pivot bearing, but spring loaded on both sides, as in the KR 2016/0063660 A1 is described.

In a further embodiment, the device can be clamped to a computer keyboard.

The subject invention of the present innovation is not only the subject of the individual claims, but also from the combination of individual protection claims with each other.
